Fig. 1 is one of the state diagrams of an electronic device 100 shown in accordance with an example embodiment. Fig. 2 is a second schematic diagram illustrating a state of the electronic device 100 according to an exemplary embodiment. As shown in fig. 1 and fig. 2, the electronic device 100 may include a housing 101 and a camera module 200 located inside the electronic device 100. Wherein the housing 101 may include an opening 1011 on a 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 interior of the housing 101 through the opening 1011. Therefore, when a user needs to use the camera module 200 to take a picture, the user can control the part of the camera module to extend out, so that the camera module is switched from the state shown in fig. 1 to the state shown in fig. 2; when the photographing requirement is not met, the electronic device 100 is controlled to retract into the electronic device 100, so that the front photographing function of the electronic device 100 is guaranteed, meanwhile, the display area of the electronic device 100 is prevented from being occupied, and the screen occupation ratio of the electronic device 100 is improved.

The camera module 200 may include a camera assembly 1 and a driving assembly 2. The driving assembly 2 can cooperate with the camera head assembly 1, so that the camera head assembly 1 can be driven to slide relative to the casing 101 when the driving assembly 2 is in an operating state.

Specifically, the camera head assembly 1 may include a camera head main body 11 and a camera head holder 12, as shown in fig. 3, the camera head main body 11 may include a lens 111 and an image sensor 112, and the like, and external image information may be acquired by cooperation of the lens 111 and the image sensor 112 and other electronic components of the camera head main body 11. The camera holder 12 may be used to fix the camera body 11, for example, the camera holder 12 may include a receiving cavity, in which at least a portion of the camera body 11 is disposed, and external image information can be acquired through the receiving cavity. Of course, the camera body 11 is described above as an exemplary embodiment, but the camera body 11 may also include other electronic components.

The drive assembly 2 may include a drive body 21 and a stroke push rod 22 cooperating with the drive body 21. The drive body 21 may include a motor and a lead screw connected to the motor, the lead screw being connected to the stroke rod 22. Therefore, when the motor rotates, the lead screw is driven to rotate, and further the stroke push rod 22 is driven to perform reciprocating translation through the lead screw, so that the stroke push rod can be driven to perform reciprocating movement. Alternatively, in other embodiments, the drive body 21 may include a motor and a gear train engaged with the motor, and the stroke push rod 22 may include a rack engaged with a final gear of the gear train, whereby when the motor rotates, the gear train rotates, thereby causing the stroke push rod 22 to translate back and forth by engaging the rack.

The stroke push rod 22 cooperates with the camera head bracket 12 to drive the camera head bracket 12 to perform reciprocating translation. Specifically, in one embodiment, as shown in fig. 4, one of the camera holder 12 and the stroke push rod 22 may include an elastic portion 3 and a first groove 4, a depth direction (a direction indicated by an arrow a in fig. 4) of the first groove 4 is perpendicular to a predetermined direction (a direction indicated by an arrow B in fig. 4), and the other of the camera holder 12 and the stroke push rod 22 extends into the first groove 4 and contacts an inner wall of the first groove 4 to drive the camera holder 12 to slide in the predetermined direction.

Based on this, the acting force between the stroke push rod 22 and the camera bracket 12 can be transmitted through the elastic part 3, and the hard connection between the stroke push rod 22 and the camera bracket 12 is avoided. When the stroke push rod 22 or the camera bracket 12 is subjected to abnormal acting force along the preset direction, at least part of the acting force can be buffered through the elastic part 3, and the risk that the camera assembly 1 slides under abnormal conditions is reduced. Especially, when a user presses the camera assembly 1 or the electronic device 100 falls carelessly to cause the portion of the camera assembly 1 extending to be stressed, the elastic part 3 can buffer part of the acting force, so that the force acting on the driving assembly 2 is reduced, the risk that the driving assembly 2 is forced to rotate is reduced, and the service life of the driving assembly 2 is prolonged.

In one embodiment, as shown in fig. 4, the camera bracket 12 may include a bracket main body 121 and an elastic part 3, the bracket main body 121 is connected to the camera main body 11, and the elastic part 3 may be connected to an end of the bracket main body 121 near the stroke push rod 22 so that the stroke push rod 22 extends into the first groove 4.

In another embodiment, as shown in fig. 5, the stroke rod 22 may include a rod body 221 and an elastic part 3, and the rod body 221 is engaged with the driving body 21 and connected with the elastic part 3. Based on this, when the driving body 21 is in the operating state, the driving pusher body 221 is moved in the direction indicated by the arrow B, and the elastic portion 3 is moved therewith to transmit the force to the camera holder 12, so that the camera holder 12 is moved in the direction indicated by the arrow B.

In each of the above embodiments, as shown in fig. 6, it is assumed that the elastic portion 3 and the first groove 4 are both located on the stroke push rod 22. Then, the stroke push rod 22 may further include a second groove 222, and the elastic portion 3 may be disposed in the second groove 222, so as to accommodate the elastic portion 3, avoid the elastic portion 3 from protruding outward, facilitate reducing the space occupation of the stroke push rod 22, and facilitate reducing the volume of the camera module 200.

Of course, as shown in fig. 7, when the elastic part 3 and the first recess 4 are both located on the camera holder 12, the camera holder 12 may include a second recess 122, and the elastic part 3 is disposed in the second recess 122. Details are not described herein.

Based on the technical solution of the present disclosure, as shown in fig. 8, take the case that 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, and as shown in fig. 7, 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 inwardly recessing the same side surface on the elastic part 3. In this way, the force can be transmitted by the part of the stroke push rod 22 extending into the first groove 41 and the part of the stroke push rod 22 extending into the first groove 42, so that the part of the stroke push rod 22 extending into the first groove 4 is broken.

In another embodiment, as shown in fig. 9, the

first grooves

41 and 42 may also be recessed and run from different side surfaces on the elastic portion 3. For example, as shown in fig. 9, first groove 41 and first groove 42 are recessed inwardly by a set of opposing surfaces on resilient portion 3. Based on this, the acting force can be transmitted to both sides of the camera support 12, which is beneficial to preventing the camera support 12 from inclining and providing the stability of the movement of the camera assembly 1.

Of course, the above description only takes the example that the number of the first grooves 4 is two, and the number of the first grooves 4 may also be three or more in other embodiments, and the disclosure does not limit this. In addition, when the elastic portion 3 and the first groove 4 are both located on the stroke pushing rod 22, a plurality of first grooves 4 may also be present, which may specifically refer to the embodiment shown in fig. 8 and 9, and will not be described herein again.

In the above embodiments, the stroke push rod 22 and the portion of the camera head bracket 12 extending into the first groove 4 are tightly fitted with the first groove 4, so as to prevent the stroke push rod 22 and the camera head bracket 12 from being separated. For example, the stroke push rod 22 can be tightly matched with the first groove 4 on the camera bracket 12; alternatively, the camera bracket 12 may be a close fit with the first groove 4 on the stroke push rod 22. In an embodiment, the stroke push rod 22 and the part of the camera support 12 extending into the first groove 4 can be adhered to the inner wall of the first groove 4 to realize fixation.

In the above embodiments, the elastic portion 3 may be made of one or more materials of silicone, rubber, and latex; the first recess 4 may be of any shape. For example, the first recess 4 may be of regular shape, for example, the first recess 4 may be cylindrical or square. For another example, the first groove 4 may also be irregular, and the portion extending into the first groove 4 may be designed and matched as needed.

Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
