In the application, the movable lens is a pop-up camera, the movable lens can be hidden in the device body in a non-use state, and the movable lens can be popped out of the device body in a use state to be used for shooting or recording. Wherein the driver 60 is switchable between a first state and a second state. The first state of the actuator 60 may be understood as a state in which the actuator 60 is connected to the micro cloud stage 100, and the second state of the actuator 60 may be understood as a state in which a movable lens is used.

With the driver 60 in the first state, the driver 60 is connected to the heat conductive member 50, and the driver 60 drives the heat conductive member 50 to switch between the first position and the second position. Under the condition that the heat conducting piece 50 is located at the first position, the heat conducting piece 50 is in contact with the automatic focusing module 20, the automatic focusing module 20 and the heat conducting piece 50 are attached to each other, and an air layer cannot be formed between the automatic focusing module 20 and the heat conducting piece 50, so that the heat dissipation efficiency of the electronic equipment is effectively improved, and the risk of heat damage is avoided.

The heat conducting silica gel pad 52 can be attached to the heat conducting plate 51 by the heat conducting gel 53. The heat-conducting silica gel pad 52 is mainly disposed at the position where the heat-conducting plate 51 is located in the second accommodating cavity, so as to ensure that the heat-conducting silica gel pad 52, the heat-conducting plate 51 and the auto-focusing module 20 can correspond to each other. In the case where the heat-conducting member 50 is located at the first position relative to the pan/tilt head motor 30, the heat-conducting silicone pad 52 contacts the auto-focusing module 20, and the heat generated by the auto-focusing module 20 is conducted to the heat-conducting silicone pad 52 and the heat-conducting plate 51, and finally is conducted out through the heat-conducting plate 51.

Under the condition that heat-conducting piece 50 is located the second position, heat-conducting piece 50 breaks away from auto focus module 20, and at this moment, auto focus module 20 can be in the interior activity of cloud platform motor 30, realizes little cloud platform 100's anti-shake function.

In some embodiments of the present invention, as shown in fig. 2 and 3, the transmission member 70 includes a connection block 71 and a first elastic member 72.

Specifically, the connection block 71 is connected to the heat conductive member 50, and the connection block 71 is provided with two first connection holes 711. First elastic member 72 the first elastic member 72 may be a spring column, and the first elastic member 72 is disposed on the connection block 71 along the first direction. Under the condition that the driving member 60 is in the first state, the driving connecting block 71 drives the first elastic member 72 to move in the first direction. When the first current supplied to the electromagnetic coil 622 disappears, the magnet 623 returns to the housing 621, the magnet 623 and the connecting block 71 are separated, and the heat conducting plate 51 automatically returns to the original position (the heat conducting plate 51 is in the second position) under the elastic force of the first elastic member 72.

According to an embodiment of the present invention, referring to fig. 3 and 6, the electronic device further includes a connector 81 and a second elastic member 82.

Specifically, the connector 81 is disposed in the first receiving cavity, and the connector 81 is provided with a second coupling hole 811 extending in the second direction. The second elastic member 82 is disposed on the connector 81 in the first direction, a first end of the second elastic member 82 is connected to the connector 81, and a second end of the second elastic member 82 is connected to the movable lens. The second elastic member 82 may be a spring, and the second elastic member 82 functions to automatically store the pop-up camera back into the inside of the main body of the apparatus when the pop-up camera does not operate.

When the actuator 60 is in the second state, the electromagnetic coil 622 and the magnet 623 interact with each other, the magnet 623 extends into the second connecting hole 811, and the magnet 623 is connected to the connector 81. At this time, the movable member 62 is disengaged from the heat conductive member 50, and the driving member 60 drives the movable lens to move through the connector 81. When the acting force between the electromagnetic coil 622 and the magnet 623 disappears, the magnet 623 returns to the housing 621, the magnet 623 is separated from the connecting block 71, and the movable lens automatically moves to the first accommodating cavity under the elastic action of the second elastic member 82 and is hidden in the device main body.

In the application, the electronic device may be an electronic product such as a mobile phone and a computer, and the movable lens may be a pop-up camera on the mobile phone. The present application, which uses a driving member 60 to drive the heat conducting plate 51 and the movable lens in a switchable manner, can also be applied to drive other components in the electronic device, and is a common implementation scheme of a common motor. Can connect glass apron, whole cloud platform module, realize hiding functions such as camera, cell-phone rear cover warp under the unoperated state.

The electronic equipment can control the micro-holder 100 and the movable lens to respectively realize corresponding functions by switching the driving piece 60 between the first state and the second state, and beneficial scenes of the electronic equipment comprise long exposure, long-time video recording (electronic anti-shaking can be opened), virtualization and the like, so that the risk reduction and the service life of an induction chip are facilitated. The electronic equipment of this application can satisfy little cloud platform 100 at the heat dissipation demand under the work scenes such as anti-shake and non-anti-shake, can satisfy the use needs of activity camera lens again, effectively reduces electronic equipment's occupation space, satisfies electronic equipment lightweight, miniaturization requirement.

The application discloses electronic equipment, under the work sight that need not the anti-shake, perhaps when little cloud platform temperature is too high, eliminate the air bed, close the anti-shake function and carry out quick radiating structure. The technical effect of switchably controlling the two movable mechanisms (the transmission member 70 and the connector 81) by one driving member 60 is to freely switch between controlling the heat-conducting member 50 and controlling the pop-up camera (movable lens). On the premise of not adding an additional motor, the movable heat conducting piece 50 is added to the micro-cloud platform 100, so that the function of reducing the temperature of the induction chip in a static working mode is realized while the anti-shaking performance in a normal working mode is not reduced completely, the function of emergently switching to a non-shaking state after the temperature exceeds an alarm line in the anti-shaking state and keeping the induction chip to continue working at a lower temperature can be realized, and the risk of heat damage is effectively avoided.

The proposal of using a movable heat conducting plate 51 loaded with a heat conducting silica gel pad 52 instead of the heat conducting gel solves the problems of durability and reliability of the heat conducting gel. The heat dissipation performance is improved under the working condition that the anti-shake operation is not required to be started, the junction temperature of the photosensitive chip is reduced, and the risk of thermal damage of the semiconductor is greatly reduced. Beneficial scenes comprise long exposure, long-time video recording (electronic anti-shake can be started), blurring and the like, so that the risk is reduced, and the service life of a chip is prolonged.
