The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

The electronic device according to the embodiment of the present application, which may be a mobile phone, a tablet, a computer, an electronic watch, or the like, is described below with reference to fig. 1 and fig. 2.

Taking a mobile phone as an example, the electronic device includes: a camera 1 and a laser filtering device 2.

Wherein, camera 1 is used for collecting the object reverberation of being shone, assembles the light to the sensitization chip on, and the sensitization chip can convert light signal into the signal of telecommunication, and the sensitization chip is located one side of camera 1 formation of image end. The laser filtering device 2 includes: a laser protection filter 24. The laser protection filter 24 is capable of cutting off laser light within a specific wavelength range, and the laser protection filter 24 also has a transmission characteristic for other laser light outside the specific wavelength range. The laser protection filter 24 may adopt filters having absorption and/or reflection characteristics for laser light in different specific wavelength ranges, and the laser protection filter 24 may be used to absorb and/or reflect laser light in a specific wavelength range, so as to transmit other laser light outside the specific wavelength range.

Because the laser is generated by atom stimulated radiation, the frequency, the emission direction, the initial phase, the polarization direction and the like of the emitted photons are consistent with those of incident photons, and the laser has the following characteristics: firstly, laser luminance is high, can produce high temperature through gathering shining on the object. Secondly, the laser has good monochromaticity and extremely narrow wavelength range, for example, the wavelength width emitted by a helium-neon gas laser can reach 10 nm. Thirdly, the laser has good directionality and the light beams are relatively concentrated. Fourth, coherence is good. Because the wavelength range of the laser is extremely narrow, the energy of the laser incident into the camera 1 can be reduced through the laser protection filter 24, and the damage of the photosensitive chip is avoided.

Thus, the laser protection filter 24 can be movably disposed on one side of the camera 1, and the laser protection filter 24 can be switched between the first position and the second position.

Under the condition that the laser protection filter 24 is at the second position, the laser protection filter 24 exposes the shooting end of the camera 1, and the camera 1 is in a light-transmitting state. As shown in fig. 2, at this time, since the camera 1 is not provided with the laser protection filter 24, external laser light will converge through the camera 1, the power density (optical power per unit area) of the laser light when reaching the camera 1 is not very high, and when the laser light reaches the photosensitive chip, the laser light is focused to the minimum, the power density reaches the maximum value, and the thermal accumulation effect of the continuous laser light at this time may damage the photosensitive chip.

Under the condition that the laser protection filter 24 is at the first position, the laser protection filter 24 shields the shooting end of the camera 1, and the camera 1 is in a filtering state. As shown in fig. 3, when external laser penetrates through the camera 1, the laser protection filter 24 can sufficiently reflect laser which is easy to damage the photosensitive chip, and transmit other laser, so that a laser shooting effect can be ensured, and damage to the photosensitive chip is avoided.

The application provides an electronic equipment, through set up the laser filter device including laser protection filter in electronic equipment, because laser protection filter can cut off the laser in the specific wavelength range, laser protection filter can switch between the first position of sheltering from the camera and the second position that exposes the camera for when having the laser of specific wavelength in the scene, can control laser protection filter and remove to the first position and cut off the laser of specific wavelength, make the camera have the function of anti laser damage. When guaranteeing electronic equipment shooting effect from this, will easily cause the laser of damage to sensitization chip can the abundant reflection or absorb, avoid laser to cause the damage to sensitization chip for electronic equipment has the function of anti laser damage, promotes user experience.

Based on the above-described embodiment, as shown in fig. 1 and 2, the laser filter device 2 includes: a first laser protection filter 21 and a second laser protection filter 22. The first laser protection filter 21 cuts off a laser wavelength different from that of the second laser protection filter 22.

When the wavelength of the incident laser is the same as the wavelength of the laser cut off by the first laser protection filter 21, the first laser protection filter 21 moves to the first position. The second laser protection filter 22 is moved to the second position. When the wavelength of the incident laser is the same as the wavelength of the laser cut off by the second laser protection filter 22, the second laser protection filter 22 moves to the first position. The first laser protection filter 21 is moved to the second position. By arranging two laser protection filters capable of cutting off different wavelengths, the camera 1 can be shielded by adjusting the corresponding laser protection filters according to the wavelength of incident laser.

In some embodiments, as shown in fig. 2 and 3, the electronic device further comprises: laser detection device 3, laser detection device 3 set up in one side of laser filter device 2, and in order to promote detection accuracy, laser filter device 2 and laser detection device 3 generally set up in same one side of electronic equipment. The laser detection device 3 is used for detecting the wavelength and the energy of laser in a scene, and comprises: a laser detection filter 31 and an energy detector 32.

The laser light transmitted by the laser detection filter 31 matches the laser wavelength cut off by the laser protection filter 24. The laser detection filter 31 is a transmission filter having a transmission characteristic for the laser light in a specific wavelength range and having a reflection and/or absorption characteristic for the light in other wavelength ranges. Energy detector 32 sets up the transmission end at laser detection filter 31, and energy detector 32 is used for detecting the wavelength and the energy of scene internal laser, because only the laser in specific wavelength range can see through laser detection filter 31, other light is reflected for energy detector 32 can only detect a specific laser, makes laser detection device 3 can detect the intensity of specific laser accurately, promotes laser detection device 3's detection control accuracy. So that the energy detector 32 can switch the laser protection filter 24 between the first position and the second position according to the detection result.

If the energy detector 32 detects that there is laser in a specific wavelength range in the scene, or if the intensity of the detected laser reaches a threshold value, the laser protection filter 24 corresponding to the specific wavelength range shields the shooting end of the camera 1.

If the energy detector 32 does not detect the laser light in the specific wavelength range in the scene, or detects that the intensity of the laser light in the specific wavelength range does not reach the threshold value, the laser protection filter 24 is moved away to expose the shooting end of the camera 1.

As necessary, as shown in fig. 2 and 3, the laser filter device 2 may be provided with a plurality of laser protection filters 24. Wherein the laser wavelengths cut off by any two laser protection filters 24 are different. Correspondingly, the electronic equipment further comprises: the laser detection device 3 includes: a plurality of laser detection filters 31. Any laser detection filter 31 is opposite to the energy detector 32, and the laser transmitted by any laser detection filter 31 matches the laser wavelength cut by one laser protection filter 24 in the plurality of laser protection filters. That is, the laser detection filters 31 correspond to the laser protection filters 24 one by one, and the same energy detector 32 is used to detect the energy of the laser light of different wavelengths.

For example, the laser filter device 2 includes: a first laser protection filter 21, a second laser protection filter 22 and a third laser protection filter 23. The laser wavelengths cut by the first laser protection filter 21, the second laser protection filter 22 and the third laser protection filter 23 are different.

The laser detection device 3 includes: the optical filter comprises a first laser detection optical filter, a second laser detection optical filter and a third laser detection optical filter. The first laser detection filter corresponds to the first laser protection filter 21, and only the laser cut by the first laser protection filter 21 can pass through. The second laser detection filter corresponds to the second laser protection filter 22, and only the laser cut off by the second laser protection filter 22 can pass through. The third laser detection filter corresponds to the third laser protection filter 23, and only the laser cut by the third laser protection filter 23 can pass through.

In the working process, when the energy detector 32 detects that the wavelength of the incident laser is the same as the wavelength of the laser cut off by the first laser protection filter 21 and the intensity of the laser reaches the threshold value, the first laser protection filter 21 moves to the first position. The second laser protection filter 22 and the third laser protection filter 23 are moved to the second position. When the energy detector 32 detects that the wavelength of the incident laser is the same as the wavelength of the laser cut off by the second laser protection filter 22 and the intensity of the laser reaches the threshold value, the second laser protection filter 22 moves to the first position. The first laser protection filter 21 and the third laser protection filter 23 move to the second position. When the energy detector 32 detects that the wavelength of the incident laser is the same as the wavelength of the laser cut off by the third laser protection filter 23 and the intensity of the laser reaches the threshold value, the third laser protection filter 23 moves to the first position. The first laser protection filter 21 and the second laser protection filter 22 move to the second position. By arranging three laser protection filters capable of cutting off different wavelengths, the camera 1 can be shielded by adjusting the corresponding laser protection filters according to the wavelength of incident laser.

In another embodiment, as shown in fig. 2 and 3, the laser filtering device 2 includes a plurality of laser protection filters 24, wherein the wavelengths of the laser lights cut off by any two laser protection filters are different, and since it is difficult for a single laser detection device 3 to detect laser lights of a plurality of specific wavelength ranges and corresponding intensities, the electronic device further includes: and in the plurality of laser detection devices 3, the laser light passed through the laser detection filter 31 in each laser detection device 3 matches the laser wavelength cut off by one laser protection filter 24 in the plurality of laser protection filters 24.

Specifically, the laser filtering device 2 includes: a first laser protection filter 21, a second laser protection filter 22 and a third laser protection filter 23. The laser wavelengths cut by the first laser protection filter 21, the second laser protection filter 22 and the third laser protection filter 23 are different. The laser detection device 3 is divided into a first laser detection device 33, a second laser detection device 34, and a third laser detection device 35. The laser passed through by the laser detection filter 31 in the first laser detection device 33, the second laser detection device 34 and the third laser detection device 35 is matched with one of the laser wavelengths cut off by the first laser protection filter 21, the second laser protection filter 22 and the third laser protection filter 23, and the energy detectors 32 are arranged in the first laser detection device 33, the second laser detection device 34 and the third laser detection device 35.

In the working process, when the energy detector 32 of the first laser detection device 33 detects that the wavelength of the incident laser is the same as the wavelength of the laser cut off by the first laser protection filter 21 and the intensity of the laser reaches the threshold value, the first laser protection filter 21 moves to the first position. The second laser protection filter 22 and the third laser protection filter 23 are moved to the second position. When the energy detector 32 of the second laser detection device 34 detects that the wavelength of the incident laser is the same as the wavelength of the laser cut-off by the second laser protection filter 22 and the intensity of the laser reaches the threshold value, the second laser protection filter 22 moves to the first position. The first laser protection filter 21 and the third laser protection filter 23 move to the second position. When the energy detector 32 of the third laser detection device detects that the wavelength of the incident laser is the same as the wavelength of the laser cut off by the third laser protection filter 23 and the intensity of the laser reaches the threshold value, the third laser protection filter 23 moves to the first position. The first laser protection filter 21 and the second laser protection filter 22 are moved to the second position.

Based on the above embodiment, the laser filtering device 2 further includes: a drive unit. The driving unit is disposed on one side of the camera 1, and the driving unit is configured to drive the laser protection filter 24 to switch between a first position and a second position.

As shown in fig. 2, when there is a laser with a specific wavelength range in a scene, the laser protection filter 24 may be driven by the driving unit to be at a first position, and the shooting end of the camera 1 is shielded by the laser protection filter 24. When no laser in a specific wavelength range exists in a scene, the laser protective filter 24 can be driven to be in the second position through the driving unit, and the shooting end of the camera 1 is exposed, so that the shooting effect of the camera 1 is improved.

Based on the above embodiment, as shown in fig. 5, the drive unit includes: a memory metal member 25.

The memory metal piece 25 is a special alloy material, mainly made of nickel-titanium alloy, can restore to the original shape after being heated and deformed and cooled, and has memory capacity. A memory metal element 25 is attached to one end of the laser protection filter 24, the memory metal element 25 being switchable between an extended configuration and a retracted configuration. The laser protection filter 24 is driven to switch between a first position and a second position in a state where the memory metal member 25 is switched between the extended configuration and the contracted configuration.

The memory metal part 25 can be a memory metal wire, and the shape of the memory metal part 25 can be adjusted by changing the voltage (or current) applied to the memory metal part 25 under the condition that the shape of the memory metal part 25 is controlled by the voltage (or current). For example, when the voltage applied to the memory metal member 25 reaches a predetermined threshold, the memory metal member 25 is extended, and the memory metal member 25 is converted from the contracted state to the extended state. When the voltage applied to the memory metal member 25 is reduced, the memory metal member 25 contracts and returns from the extended state to the contracted state.

In a non-laser environment, the camera 1 is normally used. In laser environment, for example 450nm laser, detect the energy super threshold when laser detector, can make the feedback through control system, control memory metalwork 25's electric current size makes its intensification shorten, and the laser protection light filter 24 that the drive 450nm corresponds moves the camera top, keeps the separation laser of certain time, avoids sensitization chip burn, can normally shoot simultaneously, and when laser energy was less than the threshold, memory metalwork 25 line cooling extension, the return reaches initial position.

In a laser environment, if the memory metal part 25 is disposed on a side of the laser protection filter 24 away from the camera, the memory metal part 25 drives the laser protection filter 24 to shield the shooting end of the camera 1 when the memory metal part 25 is in an extended state. When the memory metal part 25 is in the contracted state, the memory metal part 25 drives the laser protection filter 24 to expose the shooting end of the camera 1. Alternatively, as shown in fig. 5, the memory metal member 25 is disposed on the side of the laser protection filter 24 close to the camera, and when the memory metal member 25 is in the extended state, the memory metal member 25 drives the laser protection filter 24 to expose the shooting end of the camera 1. Under the condition that the memory metal part 25 is in the contracted state, the memory metal part 25 drives the laser protection filter 24 to shield the shooting end of the camera 1.

As shown in fig. 5, the electronic device further includes: a housing 4. The housing 4 is provided with a receiving cavity. The memory metal part 25 is connected with the side wall of one end of the accommodating cavity, and the memory metal part 25 is positioned between the first end of the laser protection filter 24 and the side wall of the accommodating cavity. Each laser protection filter further comprises: an elastic member 26. The elastic member 26 may be a spring, and the elastic member 26 is connected to the other end of the receiving cavity, and the elastic member 26 is located between the laser protection filter 24 and the side wall of the receiving cavity. Under the condition that the memory metal part 25 is in the extended state, the memory metal part 25 drives the laser protection filter 24 to move towards the direction away from the camera 1, the shooting end of the camera 1 is exposed, and the elastic part 26 is compressed between the laser protection filter 24 and the side wall of the accommodating cavity in a compressed state. Under the condition that the memory metal part 25 is in the contraction state, the memory metal part 25 drives the laser protection filter 24 to move towards the direction close to the camera 1, the laser protection filter 24 shields the shooting end of the camera 1, and the elastic part 26 at least restores part of the deformation to abut between the laser protection filter 24 and the side wall of the containing cavity.

In order to avoid damage to the laser protection filter 24 during the moving process, a filter carrier can be additionally arranged, and the laser protection filter 24 is arranged on the filter carrier. For example, the elastic member 26 is connected between the first end of the filter carrier and the side wall of the receiving cavity, and the memory metal member 25 is connected between the second end of the filter carrier and the side wall of the receiving cavity.

Based on the above-described embodiment, as shown in fig. 6 and 7, the drive unit includes: a magnetic drive 28 and a coil structure 27. The magnetic driving member 28 is disposed on one side of the camera 1, and the coil structure 27 is connected to the laser protection filter 24. With the coil arrangement 27 energized, the magnetic drive 28 drives the laser protection filter 24 through the coil arrangement 27 to switch between the first position and the second position.

When the laser protection filter 24 is at the second position, if the coil structure 27 is energized, the magnetic driving member 28 generates a lorentz force on the coil structure 27 in a direction close to the camera 1, and the magnetic driving member 28 drives the laser protection filter 24 to move in the direction close to the camera 1 through the coil structure 27 so as to shield the shooting end of the camera 1. Under the condition that the laser protection filter is at the first position, if the current direction is changed, the magnetic driving member 28 generates a lorentz force to the coil structure 27 in a direction away from the camera 1, and the magnetic driving member 28 drives the laser protection filter 24 to move in the direction away from the camera 1 through the coil structure 27 so as to expose the shooting end of the camera 1.

The laser filter device 2 includes: a plurality of laser protection filters 24 and slide rails 29 corresponding to the laser protection filters 24 one to one. Each slide rail 29 is stacked in sequence, and each slide rail 29 extends along one side direction of the camera 1. Each laser protection filter 24 is slidably disposed on a corresponding slide rail 29.

For example, if the laser filter device 2 includes: the first laser protection filter 21, the second laser protection filter 22 and the third laser protection filter 23 are correspondingly arranged on three sliding rails 29 which are sequentially arranged from top to bottom.

Under the condition that the first laser protection filter 21, the second laser protection filter 22 and the third laser protection filter 23 are at the second position, if the corresponding coil structures 27 are energized, the magnetic driving member 28 generates a lorentz force in the direction close to the camera 1 on the corresponding coil structures 27, and the magnetic driving member 28 drives the laser protection filter 24 to move along the slide rail 29 in the direction close to the camera 1 through the coil structures 27 so as to shield the shooting end of the camera 1. Under the condition that the first laser protection filter 21, the second laser protection filter 22 and the third laser protection filter 23 are at the first position, by changing the current direction, the magnetic driving member 28 generates a lorentz force in a direction away from the camera 1 on the corresponding coil structure 27, and the magnetic driving member 28 drives the laser protection filter 24 to move along the slide rail 29 in the direction away from the camera 1 through the coil structure 27, so as to expose the shooting end of the camera 1.

The electronic device further includes: a housing 4. The housing 4 is provided with a receiving cavity. The accommodating cavity is provided with a camera 1, a laser filtering device 2, a magnetic driving piece 28 and a plurality of sliding rails 29. The housing 4 includes a retaining wall surrounding the side and a cover plate disposed at the top, and the magnetic driving member 28 drives the laser protection filter 24 to move along the sliding rail 29 in a direction away from or close to the camera 1 through the coil structure 27.

In this embodiment, the coil structure 27 includes: a first coil and a second coil. When the laser protection filter 24 is located at the second position, the first coil is arranged at one end of the laser protection filter 24 close to the camera 1, and the second coil is arranged at one end of the laser protection filter 24 far away from the camera 1.

The magnetic drive 28 comprises: a first permanent magnet and a second permanent magnet. The first permanent magnet and the second permanent magnet can select the magnet for use, and the first permanent magnet and the second permanent magnet can be arranged along the direction of the sliding rail 29, and drive force is applied to the first coil and the second coil through the arrangement of the two permanent magnets, so that each laser protection optical filter can be quickly exposed or shielded at the shooting end of the camera 1. When the laser protection filter 24 is located at the first position, the first permanent magnet is staggered with the first coil, and the second permanent magnet is staggered with the second coil. When the laser protection filter 24 is located at the second position, the first permanent magnet is opposite to the first coil, and the second permanent magnet is opposite to the second coil.

Similarly, in order to avoid damage to the laser protection filter 24 during the moving process, a filter carrier may be added, the laser protection filter 24 is disposed on the filter carrier, the coil structure 27 is disposed on the filter carrier, and the state switching is controlled by controlling the movement of the filter carrier.

In order to facilitate control of the laser filtering means 2 and the laser detection means 3, the electronic device further comprises: and the control system is electrically connected with the energy detector 32 and is used for controlling the laser protection filter 24 to move from the second position to the first position after receiving the laser protection starting signal and controlling the laser protection filter 24 to move from the first position to the second position when not receiving the laser protection starting signal. The laser protection enable signal may be obtained by user input or fed back by the energy detector 32, sending a feedback signal to the control system in case the energy detector detects that the intensity of the laser light reaches a threshold value.

In general, the laser shielding filter 24 cuts one of a red laser beam of 638nm, a green laser beam of 520nm, and a blue laser beam of 450 nm.

At present, laser emitted by a stage laser mainly includes red light (638nm), green light (520nm), blue light (450nm), and the like, and in order to prevent three specific lasers from damaging a photosensitive chip, as shown in fig. 3, three laser protection filters 24 are provided, and the three laser protection filters 24 respectively correspond to three specific lasers of red, green, and blue.

If the laser detection device 3 detects that laser in a specific wavelength range exists in a scene and the intensity of the laser reaches a threshold value, the laser protection filter 24 corresponding to the specific wavelength range is controlled to shield the shooting end of the camera 1 and move to the first position, and other laser protection filters 24 move to the second position to expose the shooting end of the camera 1.

If the laser detection device 3 detects that two or three lasers with specific wavelength ranges exist in a scene and the intensity of the corresponding lasers reaches a threshold value, the two or three laser protection filters 24 corresponding to the two or three specific wavelength ranges are controlled to shield the shooting end of the camera 1 and move to a first position, and the other laser protection filters 24 are left, move away to expose the shooting end of the camera 1 and move to a second position.

If the laser detection device 3 does not detect the laser within the specific wavelength range in the scene, or detects that the intensity of the laser within the specific wavelength range does not reach the threshold value, all the three laser protection filters 24 are moved away to expose the shooting end of the camera 1. Therefore, the photographing effect cannot be influenced because the specific laser filtering is cut off by the laser protection filter 24 in the normal photographing scene.

In a specific example, as shown in fig. 2 and 3, the laser filter device 2 includes: a first laser protection filter 21, a second laser protection filter 22 and a third laser protection filter 23, wherein the first laser protection filter 21 has the reflection and/or absorption characteristics aiming at red specific laser (with the wavelength of 638 nm). The second laser protection filter 22 has reflection and/or absorption characteristics for green specific laser light (wavelength 520 nm). The third laser protection filter 23 has reflection and/or absorption characteristics for blue specific laser light (wavelength 450 nm). That is, the first laser protection filter 21, the second laser protection filter 22, and the third laser protection filter 23 can sequentially cut off red laser light having a laser wavelength of 638nm, green laser light having a wavelength of 520nm, and blue laser light having a wavelength of 450 nm.
