[0037] Figure 1 This is one of the schematic diagrams showing states of an electronic device 100 according to an exemplary embodiment. Figure 2 FIG. 2 is a second state diagram of an electronic device 100 according to an exemplary embodiment. Figure 1 , Figure 2 As shown, the electronic device 100 may include a housing 101 and a camera module 200 located inside the electronic device 100. The housing 101 may include an opening 1011 located on the side wall of the housing 101, and a portion of the camera module 200 may reciprocate relative to the housing 101 to extend out of the housing 102 through the opening 1011, or retract into the housing 101 through the opening 1011. In this way, when a user needs to use the camera module 200 to take a photo, the camera module 200 may be controlled to extend partially so that it can be moved out of the housing 102. Figure 1 The displayed status switches to Figure 2 and when there is no need to take pictures, it is controlled to retract into the electronic device 100, so that while ensuring the front camera function of the electronic device 100, it avoids occupying the display area of ​​the electronic device 100 and improves the screen-to-body ratio of the electronic device 100.

[0038] The camera module 200 may include a camera assembly 1 and a driving assembly 2. The driving assembly 2 may cooperate with the camera assembly 1, so that when the driving assembly 2 is in a working state, the camera assembly 1 may be driven to slide relative to the housing 101.

[0039] Specifically, the camera assembly 1 may include a camera body 11 and a camera bracket 12. Figure 3 As shown, the camera body 11 may include a lens 111 and an image sensor 112, etc., and external image information can be obtained through the cooperation of the lens 111 and the image sensor 112 and other electronic components of the camera body 11. The camera bracket 12 can be used to fix the camera body 11. For example, the camera bracket 12 may include a receiving cavity, and at least a part of the camera body 11 is disposed in the receiving cavity, and external image information can be obtained through the receiving cavity. Of course, the above is only an exemplary embodiment to illustrate the camera body 11. Of course, the camera body 11 may also include other electronic components.

[0040] The driving assembly 2 may include a driving body 21 and a travel push rod 22 that cooperates with the driving body 21. The driving body 21 may include a motor and a lead screw connected to the motor, and the lead screw is connected to the travel push rod 22. Therefore, when the motor rotates, the lead screw is driven to rotate, and the travel push rod 22 is further driven to reciprocate through the lead screw, thereby driving the travel push rod to reciprocate. Alternatively, in other embodiments, the driving body 21 may include a motor and a gear set that cooperates with the motor, and the travel push rod 22 may include a rack that cooperates with the end gear of the gear set, so that when the motor rotates, the gear set rotates, thereby driving the travel push rod 22 to reciprocate through engagement with the rack.

[0041] The travel push rod 22 cooperates with the camera bracket 12 to drive the camera bracket 12 to reciprocate. Specifically, in one embodiment, Figure 4 As shown, one of the camera bracket 12 and the travel push rod 22 may include an elastic portion 3 and a first groove 4, and the depth direction of the first groove 4 ( Figure 4 direction indicated by arrow A) and the preset direction ( Figure 4 The camera bracket 12 and the other side of the travel push rod 22 extend into the first groove 4 and contact with the inner wall of the first groove 4 to drive the camera bracket 12 to slide along the preset direction.

[0042] Based on this, the travel push rod 22 and the camera bracket 12 can transmit the force through the elastic part 3, avoiding the rigid connection between the travel push rod 22 and the camera bracket 12. In addition, when the travel push rod 22 or the camera bracket 12 is subjected to an abnormal force in a preset direction, at least part of the force can be buffered by the elastic part 3, reducing the risk of the camera assembly 1 sliding under abnormal conditions. In particular, when the user presses the camera assembly 1, or the electronic device 100 accidentally falls and causes the extended part of the camera assembly 1 to be subjected to force, part of the force can be buffered by the elastic part 3, reducing the force acting on the drive assembly 2, reducing the risk of the drive assembly 2 being forced to rotate, and helping to extend the service life of the drive assembly 2.

[0043] In one embodiment, if Figure 4 As shown, the camera bracket 12 may include a bracket body 121 and an elastic part 3, wherein the bracket body 121 is connected to the camera body 11, and the elastic part 3 may be connected to one end of the bracket body 121 close to the travel push rod 22 to facilitate the travel push rod 22 to extend into the first groove 4.

[0044] In another embodiment, if Figure 5As shown, the travel push rod 22 may include a push rod body 221 and an elastic part 3, wherein the push rod body 221 cooperates with the driving body 21 and is connected to the elastic part 3. Based on this, when the driving body 21 is in a working state, the driving push rod body 221 moves in the direction indicated by the arrow B, so that the elastic part 3 moves accordingly, so as to transmit the force to the camera bracket 12, so that the camera bracket 12 moves in the direction indicated by the arrow B.

[0045] In the above embodiments, Figure 6 As shown, it is assumed that the elastic part 3 and the first groove 4 are both located on the travel push rod 22. Then, the travel push rod 22 may also include a second groove 222, and the elastic part 3 may be arranged in the second groove 222 to accommodate the elastic part 3 and prevent the elastic part 3 from bulging outward, which is beneficial to reducing the space occupied by the travel push rod 22 and the volume of the camera module 200.

[0046] Of course, if Figure 7 As shown, when the elastic part 3 and the first groove 4 are both located on the camera bracket 12, the camera bracket 12 may include a second groove 122, and the elastic part 3 is disposed in the second groove 122. The details are not repeated here.

[0047] Based on the technical solution disclosed in this disclosure, Figure 8 As shown, the elastic part 3 and the first groove 4 are both located on the camera bracket 12. The camera bracket 12 may include a plurality of first grooves 4, such as Figure 7 As shown in the figure, the camera bracket 12 may include a first groove 41 and a first groove 42, and the first groove 41 and the first groove 42 may be formed by the same side surface of the elastic part 3 being recessed inwardly. Based on this, the part of the stroke push rod 22 extending into the first groove 41 and the part extending into the first groove 42 can transmit the force together, so that the part of the stroke push rod 22 extending into the first groove 4 is broken.

[0048] In another embodiment, if Fig. 9 As shown, the first groove 41 and the first groove 42 may also be recessed inwardly from different side surfaces of the elastic portion 3. Fig. 9 As shown, the first groove 41 and the first groove 42 are recessed inwardly from a set of opposite surfaces on the elastic part 3. Based on this, the force can be transmitted to both sides of the camera bracket 12, which is beneficial to prevent the camera bracket 12 from tilting and provide stability for the movement of the camera assembly 1.

[0049] Of course, the above description is based on the example that the number of the first grooves 4 is two. In other embodiments, the number of the first grooves 4 can also be three or more, and the present disclosure is not limited to this. In addition, when the elastic portion 3 and the first groove 4 are both located on the stroke push rod 22, there can also be multiple first grooves 4. For details, please refer to Figure 8 and Fig. 9 The illustrated embodiments will not be described in detail here.

[0050] In the above-mentioned embodiments, the travel push rod 22 and the portion of the camera bracket 12 extending into the first groove 4 are tightly matched with the first groove 4 to prevent the travel push rod 22 and the camera bracket 12 from being separated. For example, the travel push rod 22 may be tightly matched with the first groove 4 on the camera bracket 12; or the camera bracket 12 may be tightly matched with the first groove 4 on the travel push rod 22. In one embodiment, the portions of the travel push rod 22 and the camera bracket 12 extending into the first groove 4 may be bonded to the inner wall of the first groove 4 to achieve fixation.

[0051] In the above embodiments, the elastic part 3 can be made of one or more materials selected from silicone, rubber and latex; the first groove 4 can be of any shape. For example, the first groove 4 can be of a regular shape, such as a cylindrical or square shape. For another example, the first groove 4 can be of an irregular shape, and the portion extending into the first groove 4 can be designed and matched as needed.

[0052] In this example, those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the disclosure disclosed herein.
