Background technique

Television sets have already become one of the necessary home appliances for every household. Many people get information by watching TV programs. In order to further explore possible business opportunities, many system manufacturers provide diversified service items through TV programs, so that more people can obtain the required services through TV programs.

Take the current digital TVs equipped with network camera modules as an example, all of them have the function of supporting network video. When the user end and the remote end are connected by image and video, the user end can transmit the image of the user end (including the user and the background behind him) to the remote end through the network camera module of the video product.

However, the IP camera modules equipped with digital TVs in the market can be roughly divided into plug-in IP camera modules and built-in IP camera modules. For the plug-in network camera module, the signal wires are exposed to the digital TV, so complicated wiring will make the digital TV unattractive as a whole, and the signal wires often accumulate dust, causing troubles for users to clean. For the built-in network camera module, when the user terminal stops using the network camera module, hackers may still activate the network camera module through the network, and obtain the image of the user terminal without warning, endangering the user The privacy and security of end users.

The second tooth 142b of the movable gear 142 is annularly disposed on the second side surface 142a and meshes with the first tooth 140b of the fixed gear 140 (as shown in FIG. 5A ). The second side surface 142a of the movable gear 142 is perpendicular to the rotational axis of the movable gear 142 (as shown by the dotted line in FIG. Axis of rotation. In addition, the camera module 16 of the electronic device 1 has a groove 160 . The outer edge of the movable gear 142 engages with the groove 160 of the camera module 16 . The elastic member 18 of the electronic device 1 is accommodated in the groove 160 of the camera module 16 and is located between the movable gear 142 of the transmission module 14 and the bottom of the groove 160 . Since the camera module 16 is limited by the casing 10 in the rotational axis of the fixed gear 140 and the transmission gear, the elastic member 18 is compressed between the movable gear 142 of the transmission module 14 and the bottom of the groove 160 .

In other words, the camera module 16 of the electronic device 1 is driven by the movable gear 142 of the transmission module 14 , and then rotates relative to the casing 10 to selectively assume the open state shown in FIG. 2A or the closed state shown in FIG. 2B .

As shown in FIG. 5B , in this embodiment, when an external force is applied to the camera module 16, so that the camera module 16 drives the movable gear 142 to rotate relative to the fixed gear 140, the second tooth 142b of the movable gear 142 will be in contact with that of the fixed gear 140. The first tooth 140b is disengaged, and the movable gear 142 will move away from the first side surface 140a of the fixed gear 140, and compress the elastic member 18 toward the bottom of the groove 160 of the camera module 16 (that is, the movable gear 142 will move toward the bottom of the groove 160 in FIG. 5B in the direction indicated by the thick arrow). That is to say, this embodiment is a specially designed connection mechanism between the fixed gear 140 and the movable gear 142, so when the torque generated by the external force on the movable gear 142 and the fixed gear 140 is greater than the elastic force of the elastic member 18, the movable gear 142 will It will move toward the elastic member 18 and retreat relative to the fixed gear 140 (because the second tooth 142b of the movable gear 142 will be squeezed by the first tooth 140b of the fixed gear 140 and climb to the top of the first tooth 140b). With the above connection mechanism, the electronic device 1 of this embodiment can protect the transmission module 14, avoiding the worm 144 of the transmission module 14, the first transmission gear set 146a, the second transmission gear set 146b, and the third transmission gear set. 146c, the fourth transmission gear set 146d, the fixed gear 140 or the movable gear 142 are damaged.

In fact, when the external force makes the camera module 16 rotate relative to the housing 10, the second tooth 142b of the movable gear 142 will reciprocally engage and separate from the first tooth 140b of the fixed gear 140, which involves the external force making the camera module 16 It depends on the angle of rotation relative to the housing 10. After the external force disappears, the elastic force of the elastic member 18 will push the movable gear 142 towards the fixed gear 140, so that the second tooth 142b of the movable gear 142 is meshed with the first tooth 140b of the fixed gear 140 again, so that the camera module 16 can be Driven by the drive module 12 as usual.

As shown in FIG. 2A , in this embodiment, the camera module 16 of the electronic device 1 has opposite first side walls 162 and second side walls 164 .
