Detailed ways

In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

FIG. 1 schematically shows a head-mounted smart device 1 according to an embodiment of the present invention as a whole. As shown in FIG. 1 , the head-mounted smart device 1 (hereinafter simply referred to as the smart device 1 ) includes a smart component 100 and a headband 200 connected to the smart component 100 . The headband 200 is configured to be foldable. For example, the headband 200 is provided with an elastic member 300 made of a shape memory alloy, and the elastic member 300 is thermally connected with the smart assembly 100 .

In this way, by utilizing the shape memory properties of the shape memory alloy, the extended state and the storage state of the headband 200 can be precisely controlled, thereby facilitating the storage of the smart device 1 and the use of the user. In another embodiment, the headband 200 is connected to the smart device 1 in a detachable manner.

When the smart component 100 is working, each electronic component of the smart component 100 will generate heat, so that the smart component 100 forms a heating element of the smart device 1 . For example, for smart glasses, when the smart component 100 is working, its temperature may reach above 40°C. In this case, the transformation temperature of the shape memory alloy used in the present invention is between 40°C and 45°C. In addition, when the temperature of the shape memory alloy is lower than its transformation temperature, the elastic member 300 is in a folded state; when the temperature of the shape memory alloy is higher than its transformation temperature, the elastic member 300 is in an extended state. In this way, the deformation of the elastic member 300 can be controlled by the ambient temperature and the heat dissipated by the smart assembly 100 , so as to precisely control the extended state and the storage state of the headband 200 .

For example, when the ambient temperature is 15°C, after the smart device 1 is taken out of the storage box, the elastic member 300 can be preheated to a temperature higher than the transformation temperature of the shape memory alloy, so that the elastic member 300 becomes stretched state, the headband 200 also conforms to the extended state for use by the user. In this case, the heat dissipated by the smart component 100 can keep the elastic member 300 in an extended state. When accommodating the smart device 1, the temperature of the elastic member 300 needs to be lowered below its transition temperature, and there is no need to pay special attention to the folded shape of the elastic member 300, which is determined by the characteristics of the shape memory alloy. Therefore, it is greatly convenient for the user to store the smart device 1 . In this case, the elastic member 300 forms at least one folded area of the headband 200 .

In addition, the elastic sheet 300 also has very good elasticity above the transformation temperature of the shape memory alloy. In this way, the deformability of the headband 200 can be greatly improved to adapt to the shape of the head of different users.

In a specific embodiment, the shape memory alloy is TiNi alloy or TiNiCu alloy. By controlling the element ratio of the alloy and an appropriate heat treatment process, the transformation temperature of the alloy can be controlled between 40°C and 45°C, which will not be repeated here.

As described above, when the smart assembly 100 is working, each electronic component of the smart assembly 100 will generate heat. The heating of the electronic components may cause the operation speed of the smart device 100 to be slowed down, and may even cause the delay of images and/or sounds, which may result in poor user experience. In the smart device 1 of the present application, the smart component 100 can not only dissipate heat to the surrounding environment through itself, but also the heat generated by the smart component 100 can be transferred to the elastic member 300 on the headband to assist heat dissipation, which is equivalent to increasing the heat dissipation of the smart component 100 area. Therefore, the headband 200 with the elastic member 300 can greatly improve the heat dissipation capability of the smart assembly 100 , thereby improving the user's experience of using the smart device 1 .

In one embodiment, the elastic member 300 is configured as an elastic metal sheet body 301 . The elastic metal sheet body 301 has good heat transfer and heat dissipation performance, thereby helping to dissipate heat to the smart component 100 . In addition, the elastic metal sheet body 301 is easier to deform and has good elasticity due to its smaller thickness, which helps to stably wear the smart device 1 on the head, and the user can also see a more stable image, thereby The user experience is further improved.

In another embodiment, the thickness of the elastic metal sheet body 301 may be greater than or equal to 0.1 mm and less than or equal to 3.5 mm, preferably greater than or equal to 0.3 mm and less than or equal to 1.2 mm, more preferably 0.8 mm. The inventor found that the elastic metal sheet body 301 with this thickness is relatively light and thin, not only has better heat dissipation capacity, but also has a fast deformation speed when the temperature is higher than the transformation temperature of the shape memory alloy, and has a small weight and good elasticity. It helps to reduce the weight of the smart device 1, and the wearing of the smart device 1 is also more stable.

As shown in FIG. 2 , the elastic member 300 is provided in the body 201 . In this way, the elastic member 300 cannot be seen from the outside, thereby improving the aesthetics of the smart device 1 . In a preferred embodiment, the body 201 is provided with a plurality of heat dissipation holes 310 extending to the elastic member 300 (as shown in FIG. 1 ). The heat dissipation holes help to improve the heat dissipation capability of the elastic member 300 without affecting the aesthetics of the smart device 1 .

In one embodiment, as shown in FIG. 3 , an accommodating groove 202 is provided in the body 201 , and the elastic member 300 is installed in the accommodating groove 202 . More preferably, the elastic member 300 and the main body 201 are also fixedly connected together by screws, so that the elastic member 300 is arranged in the main body 201 .

In a specific embodiment, for the elastic metal sheet body 301 , screw holes are preset on the elastic metal sheet body 301 , and screw holes are correspondingly preset on the main body 201 . After being installed in the accommodating groove 202, the screw holes on the elastic metal body 301 are aligned with the screw holes on the main body 201, and then the screws are installed in the two screw holes, thereby fixing the elastic metal body 301 on the main body 201.

In another specific embodiment, as shown in FIG. 4 , two accommodating cavities 204 are provided at intervals on the body 201 , and a groove 205 is formed between the two accommodating cavities 204 . The accommodating cavity 204 and the groove 205 together form the accommodating groove of the body 201 . The body 201 also includes a cover plate (not shown) that fits into the groove 205 . Both ends of the elastic metal sheet body 301 are respectively inserted into the two receiving cavities 204 (as shown by the dotted lines in FIG. 4 ), and the whole is located in the groove 205 . The cover plate is detachably installed in the groove 205 and covers the elastic metal sheet body 301 , so that the elastic metal sheet body 301 is arranged in the main body 201 .

In another embodiment, the body is a plastic part, so that the elastic metal sheet body 301 can be directly fixed in the body 201 by injection molding.

A signal line 210 is also provided in the headband 200 of the smart device 1 to realize data transmission. As shown in FIG. 3 , the signal line 210 extends over the elastic member 300 in a fixed attachment manner. For the planar elastic metal sheet body 301 , it is more beneficial to fix the signal line 210 . In the embodiment shown in FIG. 4 , the signal line 210 may also extend over the elastic metal sheet body 301 in a fixed attachment manner. For example, the signal line 210 may be fixedly attached to the elastic metal sheet 301 by means of adhesive or by forming an extension groove on the surface of the elastic metal sheet 301 . When the headband 200 is accommodated, the elastic metal sheet body 301 may have a larger bending radius (eg, a bending radius of 2 mm to 100 mm, preferably 1.5 mm to 2.5 mm, more preferably 1.8 mm). Therefore, when the elastic metal sheet body 301 is bent, the signal wire 210 fixedly attached to the elastic metal sheet body 301 will bend with a larger bending radius according to the bending of the elastic metal sheet body 301 , which reduces the number of signal wires. 210 The probability of accidental breakage increases the service life of the smart device 1 .

FIG. 5 schematically shows the whole of glasses 6 for augmented reality according to another embodiment of the present invention. The glasses 6 are similar to the smart device 1 described above, and only the differences between the two are described here. As shown in FIG. 5 , the glasses 6 include a spectacle frame 600 and a temple 700 connected to the spectacle frame 600 . The smart component 100 as described above is provided on the eyeglass frame 600, and the elastic metal sheet 701 made of shape memory alloy is provided on the temple 700 (in FIG. 5, the temple 700 is cut away and shown ). The elastic metal sheet body 701 is thermally connected to the smart assembly 100 and forms a folded portion of the temple 700 . The elastic metal sheet body 701 is the same as the elastic metal sheet body 301 described above, so it also has shape memory, good heat transfer and heat dissipation performance and has a large bending radius. In this way, the traditional mechanical axis for realizing the folding of the temples 700 is omitted in the glasses 6 , thereby greatly reducing the number of parts of the glasses 6 and reducing the manufacturing difficulty and manufacturing cost of the glasses 6 .

It should be understood that "the elastic metal sheet body 701 is thermally connected to the smart component 100" means that the elastic metal sheet body 701 is directly connected to the smart component 100, and may also be indirectly connected through a heat transfer member. In one embodiment, the spectacle frame 600 is made of aluminum or an aluminum alloy, and the elastic metal sheet 701 and the smart component 100 are indirectly connected through the spectacle frame 600 . Aluminum or aluminum alloy has good heat dissipation performance and high heat transfer coefficient, which helps to quickly transfer the heat generated by the smart component 100 to the elastic metal sheet body 701 , thereby further improving the heat dissipation capability of the glasses 6 or the smart component 100 . In addition, the density of aluminum or aluminum alloy is low, which helps to reduce the weight of the glasses 6 , which also helps to improve the user's feeling of using the glasses 6 . Furthermore, the aluminum or aluminum alloy also helps the heat transfer between the eyeglass frame 600 and the elastic metal sheet body 701, thereby helping the temperature of the elastic metal sheet body 701 to quickly reach and maintain above the transformation temperature of the shape memory alloy, Then, the temples 700 are in an extended state.

As mentioned above, the transformation temperature of the shape memory alloy is between 40°C and 45°C, and the temperature may reach above 40°C when the smart component 100 is working. When the temperature of the shape memory alloy is lower than its transformation temperature, the elastic metal sheet 701 is in a folded state; when the temperature of the shape memory alloy is higher than its transformation temperature, the elastic metal sheet 701 is in an extended state. In this way, through the ambient temperature and the heat dissipated by the smart component 100 , the stretched state and the storage state of the elastic metal sheet body 701 can be controlled, so that the temple 700 is in the stretched state or the stored state. For example, when the temperature of the elastic metal sheet body 701 is higher than its transition temperature, the elastic metal sheet body 701 is in an extended state, the temples 700 are extended and the glasses 6 are in a wearable state. When accommodating the glasses 6, the temperature of the elastic metal piece 701 needs to be lowered below the transition temperature thereof.

In one embodiment, the shape memory alloy is a TiNi alloy or a TiNiCu alloy. The inventors discovered that shape memory alloys are also superelastic above the transformation temperature of such shape memory alloys. In this way, the temple 700 has a larger bending range and is less prone to damage, which helps to adapt to the size of the head of different wearers.

Preferably, the elastic metal sheet body 701 is located in the 1/3 area of the temple 700 connected to the spectacle frame 600 . The inventor found that under this structure, when the user wears the glasses 6, the elastic metal sheet 701 will not contact the wearer's face, which avoids the high temperature elastic metal sheet 701 causing discomfort to the wearer's face.

In addition, the temple 700 further includes a main body 710 , and an accommodating groove 711 is provided in the main body 710 , and the elastic metal sheet body 701 is installed in the accommodating groove 711 . The elastic metal sheet body 701 can also be fixedly connected with the main body 710 by screws 712 . The body 710 is provided with a plurality of heat dissipation holes 713 extending to the elastic metal sheet body 701 . A signal line 714 is also provided in the temple 700 , and the signal line 714 extends over the elastic metal sheet body 701 in a fixed attachment manner. These features are similar to those described above and will not be repeated here.

It should be understood that, in this application, the smart assembly 100 may include an image assembly, and when using the smart device 1, the user can wear the headband 200 on the head, and make the smart assembly 100 in front of the eyes, so that the user can The image produced by the smart component 100 can be seen. The smart assembly 100 can be imaged by virtual reality technology, which includes but is not limited to AR technology, VR technology and MR technology. In another embodiment, the smart component 100 may further include a sound component to generate sound adapted to the image. In addition, the smart component 100 may also be a separate audio component.
