[0047] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0048] The camera module and the electronic device provided by the practical new embodiment will be described in detail below in combination with specific embodiments and application scenarios. Figures 1-16

[0049] In the first aspect, as shown in Figure 1 and Figure 2 , the present application embodiment provides a camera module 1, comprising: a base 11, a flip cover 12, a camera, a drive member 13 and a damping structure;

[0050] The camera is arranged on the flip cover 12, the flip cover 12 is rotatably arranged on the base 11, the drive member 13 is connected with the flip cover 12 to drive the flip cover 12 to rotate relative to the base 11.

[0051] The damping structure is arranged between the flip cover 12 and the base 11, and when the drive member 13 is in the off or standby state, the damping structure is used to control the side surface of the flip cover 12 to be attached to the base 11 to eliminate the virtual position error.

[0052] It can be understood that the flip cover 12 is provided with a first hinge member, the base 11 is provided with a second hinge member, and the first hinge member and the second hinge member can be rotatably matched to realize the rotation of the flip cover 12 relative to the base 11; wherein the rotation angle of the flip cover 12 relative to the base 11 can be configured to be between 0° and 270°.

[0053] The camera is detachably mounted on the flip cover 12, and the lens of the camera faces away from the base 11 on one side of the flip cover 12, so as to avoid the rotation of the flip cover 12 relative to the base 11 affecting the normal work of the camera.

[0054] ​Further, the damping structure does not affect the flipping movement of the cover 12 relative to the base 11, and the damping structure can control the cover 12 to hover at any flipping angle relative to the base 11, especially when the driving member 13 is in the off or standby state, and the damping structure is used to ensure that one side of the cover 12 facing the base 11 is kept in contact with the base 11.

[0055] Exemplarily, the damping structure can be two friction surfaces capable of achieving sliding contact, which are arranged on the first and second hinge members one by one.

[0056] Of course, the damping structure can also be a hydraulic damping assembly or an elastic damping assembly arranged between the cover 12 and the base 11, as long as it can ensure that the cover 12 is kept in contact with the base 11 when the driving member 13 is in the off or standby state.

[0057] When the driving member 13 is in the off or standby state, the flipping angle of the cover 12 relative to the base 11 can be considered as 0°, and when the driving member 13 is in the working state, the flipping angle of the cover 12 relative to the base 11 can be considered as greater than 0°.

[0058] The side of the base 11 facing the cover 12 is provided with a groove structure 1101, and when the flipping angle of the cover 12 relative to the base 11 is 0°, the cover 12 is arranged in the groove structure 1101, and the side of the cover 12 facing the base 11 is in contact with the groove bottom surface of the groove structure 1101.

[0059] As can be seen from the above, by arranging the damping structure between the cover 12 and the base 11, the position of the cover 12 relative to the base 11 can be limited by the damping structure when the driving member 13 is in the off or standby state, so that the cover 12 does not appear to open a certain angle relative to the base 11 under the driving of the driving member 13, and the camera module 1 is in the closed state, the virtual position error between the cover 12 and the base 11 is eliminated, the appearance of the camera module 1 arranged on the electronic equipment is ensured, and the camera module 1 is not easy to be physically damaged due to accidental touch.

[0060] In some embodiments, as shown in Figure 2 , Figure 3 , Figure 7 and Figure 11 , the cover 12 has a first hinge shaft 121, and the first hinge shaft 121 is connected with the driving member 13; the base 11 is provided with a first shaft sleeve 111, and the first hinge shaft 121 is rotatably inserted into the first shaft sleeve 111;

[0061] The damping structure comprises an elastic piece 1401, which is arranged between the circumferential wall of the first hinged shaft 121 and the inner wall of the first shaft sleeve 111 and abuts against the first hinged shaft 121.

[0062] It can be understood that, since the first hinged shaft 121 is rotatably inserted into the first shaft sleeve 111, the flip cover 12 is flipped relative to the middle axis of the first shaft sleeve 111 relative to the base 11. The output end of the driving piece 13 is connected with the first hinged shaft 121, so as to drive the flip cover 12 to flip relative to the base 11 through the first hinged shaft 121.

[0063] The elastic piece 1401 can be a deformable elastic piece or an elastic sleeve, and when the first hinged shaft 121 is inserted into the first shaft sleeve 111, the elastic piece 1401 is deformed in the gap between the circumferential wall of the first hinged shaft 121 and the inner wall of the first shaft sleeve 111 under the extrusion of the first hinged shaft 121, so as to apply an elastic force to the circumferential wall of the first hinged shaft 121. This makes the first hinged shaft 121 have a certain damping force when rotating in the first shaft sleeve 111, and ensures that the flip cover 12 is kept in close contact with the base 11 under the action of the damping force when the driving piece 13 is in the off or standby state.

[0064] In some embodiments, as shown in Figure 3 and Figure 11 , the circumferential wall of the first hinged shaft 121 is provided with a groove 1211 extending along the circumference of the first hinged shaft 121; the elastic piece 1401 is annular and embedded in the groove 1211; and the elastic piece 1401 abuts between the groove bottom of the groove 1211 and the inner wall of the first shaft sleeve 111.

[0065] Specifically, the elastic piece 1401 can be a rubber ring or a silica gel ring, the thickness of the elastic piece 1401 in the axial direction is adapted to the groove width of the groove 1211, and the thickness of the elastic piece 1401 in the radial direction is greater than the groove depth of the groove 1211, so as to realize that the elastic piece 1401 abuts between the groove bottom of the groove 1211 and the inner wall of the first shaft sleeve 111.

[0066] In some embodiments, as shown in Figure 3 and Figure 7 , in order to ensure that the first hinged shaft 121 rotates smoothly in the first shaft sleeve 111 and that the first hinged shaft 121 can uniformly receive the damping force in rotation, the circumferential wall of the first hinged shaft 121 is provided with a plurality of grooves 1211, which are sequentially and spaced apart along the axial direction of the first hinged shaft 121; and the elastic piece 1401 is provided with a plurality of elastic pieces 1401, which are embedded in the plurality of grooves 1211 one by one.

[0067] Exemplarily, the two grooves 1211 are arranged at two ends of the first shaft sleeve 111, one of which is arranged at the end of the first shaft sleeve 111 close to the cover 12, and the other of which is arranged at the end of the first shaft sleeve 111 away from the cover 12. This design realizes the arrangement of two elastic members 1401 between the peripheral wall of the first hinge shaft 121 and the inner wall of the first shaft sleeve 111, which not only ensures that the first hinge shaft 121 is uniformly subjected to damping force in rotation, but also prevents the cover 12 from being unable to turn due to excessive damping force.

[0068] In some embodiments, as shown in Figure 5 , Figure 9 and Figure 10 , the first hinge shaft 121 is internally provided with a plug-in hole 1210, the inner wall of the plug-in hole 1210 is provided with a first plane 12101 and a second plane 12102, the first plane 12101 and the second plane 12102 are opposite to each other and are arranged in parallel;

[0069] The driving member 13 comprises a driving motor 131 and a rotating shaft 132 in transmission connection with the driving motor 131, the side wall of the rotating shaft 132 is provided with a third plane 1321 and a fourth plane 1322, the third plane 1321 and the fourth plane 1322 are opposite to each other and are arranged in parallel; the rotating shaft 132 is inserted into the plug-in hole 1210, the third plane 1321 and the first plane 12101 are attached, and the fourth plane 1322 and the second plane 12102 are attached.

[0070] It can be understood that when the driving member 13 drives the cover 12 to turn towards the side away from the base 11, the third plane 1321 on the side wall of the rotating shaft 132 cooperates with the first plane 12101 in the plug-in hole 1210, which can effectively reduce the possible rotation virtual position of the driving member 13 in driving the cover 12 to turn.

[0071] Correspondingly, when the driving member 13 drives the cover 12 to turn towards the side close to the base 11, the fourth plane 1322 on the side wall of the rotating shaft 132 cooperates with the second plane 12102 in the plug-in hole 1210, which can effectively reduce the possible rotation virtual position of the driving member 13 in driving the cover 12 to turn.

[0072] Further, the distance between the third plane 1321 and the fourth plane 1322 is smaller than the diameter of the rotating shaft 132, and the diameter of the rotating shaft 132 is smaller than the inner diameter of the plug-in hole 1210.

[0073] It can be understood that the diameter of the rotating shaft 132 is the diameter of the arc-shaped side wall of the rotating shaft 132 excluding the third plane 1321 and the fourth plane 1322, and the inner diameter of the plug-in hole 1210 is the diameter of the arc-shaped inner wall of the plug-in hole 1210 excluding the first plane 12101 and the second plane 12102.

[0074] In the prior art, in some assembly scenarios, a rectangular shaft body is used in combination with a shaft body-adapted plug-in shaft sleeve. Although this design can avoid the occurrence of rotational virtual position of the shaft body and the shaft sleeve during rotation, it is difficult to insert the shaft body into the shaft sleeve due to processing errors. In another scenario, a "D"-shaped shaft body is used in combination with a shaft body-adapted plug-in shaft sleeve. Although this design facilitates the insertion of the shaft body into the shaft sleeve, the shaft body does not have rotational virtual position when rotating in one rotational direction relative to the shaft sleeve, but has rotational virtual position when rotating in the other rotational direction relative to the shaft sleeve.

[0075] However, in the embodiment, the interval between the third plane 1321 and the fourth plane 1322 is less than the diameter of the rotating shaft 132, and the diameter of the rotating shaft 132 is less than the inner diameter of the plug-in hole 1210, so that the rotating shaft 132 can be smoothly inserted into the plug-in hole 1210, the processing difficulty of the rotating shaft 132 is reduced, the assembly of the flip cover 12 on the base 11 is facilitated, and the rotating shaft 132 does not have rotational virtual position relative to the first hinge shaft 121 regardless of the clockwise rotation or the counterclockwise rotation of the rotating shaft 132.

[0076] In some embodiments, as shown in Figure 2 and Figure 3 In order to facilitate the installation of the flip cover 12, the flip cover 12 also has a second hinge shaft 122, and the first hinge shaft 121 and the second hinge shaft 122 are arranged on both sides of the flip cover 12 along the rotating shaft 132 of the flip cover 12; the base 11 is also provided with a second shaft sleeve 112, and the second shaft sleeve 112 is detachably connected with the base 11; and the second hinge shaft 122 is rotatably inserted into the second shaft sleeve 112.

[0077] Based on the scheme shown in the above embodiment, the assembly process of the camera module 1 is described in detail. Figures 5 to 8

[0078] As shown in Figure 5 The driving motor 131 and the gear assembly are installed in the corresponding housing of the driving member 13, the output end of the driving motor 131 is connected with the input end of the gear assembly, and the output end of the gear assembly is connected with the rotating shaft 132. The gear assembly is used to achieve speed control between the driving motor 131 and the rotating shaft 132.

[0079] As shown in Figure 6 The rotating shaft 132 of the driving member 13 is arranged opposite to the first shaft sleeve 111 of the base 11, and the driving member 13 is installed on the first side edge of the base 11 in this direction by using bolts.

[0080] As shown in Figure 7 ​As shown in the drawings, after the elastic member 1401 is sleeved on the first hinge shaft 121 of the flip cover 12, the first hinge shaft 121 is arranged opposite to the first shaft sleeve 111 of the base 11, then the first hinge shaft 121 is inserted into the first shaft sleeve 111 in this direction, and the rotating shaft 132 is inserted into the insertion hole 1210 of the first hinge shaft 121.

[0081] As shown in the drawings, the second shaft sleeve 112 is arranged opposite to the second hinge shaft 122 of the flip cover 12, and the second shaft sleeve 112 is sleeved on the outside of the second hinge shaft 122 in this direction. The driving member 13 is installed on the second side edge of the base 11 by means of a bolt, and the first side edge and the second side edge are arranged opposite to the rotating shaft 132 line of the flip cover 12. Figure 8

[0082] In some embodiments, as shown in the drawings, the damping structure further comprises a first magnetic attraction member 1411 and a second magnetic attraction member 1412; the first magnetic attraction member 1411 is arranged on the flip cover 12, and the second magnetic attraction member 1412 is arranged on the base 11; when the driving member 13 is in the shutdown or standby state, the first magnetic attraction member 1411 and the second magnetic attraction member 1412 are attracted to each other. Figure 2 Figure 4 Figure 12 It can be understood that when the driving member 13 controls the flip angle of the flip cover 12 to be 0°, the first magnetic attraction member 1411 and the second magnetic attraction member 1412 are attracted to each other to ensure that the side of the flip cover 12 facing the base 11 is attached to the base 11. This design can assist the elastic member 1401 shown in the above embodiment to prevent the flip cover 12 from opening relative to the base 11 under the driving of the driving member 13, thereby ensuring that the camera module 1 is in a closed state.

[0083] In some examples, as shown in the drawings, the side of the base 11 away from the flip cover 12 is provided with a mounting groove 1102 for mounting the second magnetic attraction member 1412.

[0084] In actual application, the second magnetic attraction member 1412 is in a sheet shape, and the size of the second magnetic attraction member 1412 can be set according to actual needs to avoid that the magnetic attraction force between the first magnetic attraction member 1411 and the second magnetic attraction member 1412 is too large to affect the normal flip control of the flip cover 12 by the driving member 13. Figure 4 Figure 12 In some examples, as shown in the drawings, the side of the base 11 away from the flip cover 12 is provided with a mounting groove 1102 for mounting the second magnetic attraction member 1412.

[0085] In actual application, the second magnetic attraction member 1412 is in a sheet shape, and the size of the second magnetic attraction member 1412 can be set according to actual needs to avoid that the magnetic attraction force between the first magnetic attraction member 1411 and the second magnetic attraction member 1412 is too large to affect the normal flip control of the flip cover 12 by the driving member 13.

[0086] In some examples, as shown in the drawings, the side of the base 11 away from the flip cover 12 is provided with a mounting groove 1102 for mounting the second magnetic attraction member 1412. In some examples, as shown in the drawings, the side of the base 11 away from the flip cover 12 is provided with a mounting groove 1102 for mounting the second magnetic attraction member 1412.​​​

[0087] In some embodiments, as shown in Figure 2 and Figure 12 , the flip cover 12 comprises a first cover body 1201 and a second cover body 1202; the first cover body 1201 and the second cover body 1202 are connected to form a containing cavity for accommodating the camera between the first cover body 1201 and the second cover body 1202; at least part of the first cover body 1201 is formed as a first magnetic attraction member 1411, and the second cover body 1202 is provided with a light passage opening on the side away from the first cover body 1201, the light passage opening being in communication with the containing cavity and being configured to be arranged opposite to the lens of the camera so that the camera can take pictures of the surrounding environment.

[0088] Wherein, when the driving member 13 is in the off or standby state, the side surface of the first cover body 1201 away from the second cover body 1202 is attached to the base 11.

[0089] In the second aspect, as shown in Figure 13 , Figure 15 and Figure 16 , the utility model also provides an electronic device, including device body 2 and the camera module 1 described in any one of the above, the base 11 and device body 2 are connected.

[0090] It can be understood that the electronic device can be a learning machine and a scanning pen, and the following will be illustrated by taking the learning machine as an example.

[0091] For the learning machine, the base 11 is arranged on the back of the device body 2, and the front of the device body 2 is a display screen. In actual application, the driving member 13 controls the flip cover 12 to flip relative to the base 11, which can change the shooting angle of the camera on the flip cover 12 and ensure that the camera can take pictures of the work placed in different positions on the front side of the device body 2.

[0092] For the camera module 1 of the learning machine in the prior art, when the driving member 13 controls the flip angle of the flip cover 12 to be 0°, due to the non-eliminable gear gap of the driving member 13, the flip cover 12 will have a small opening angle relative to the base 11 (see Figure 14 ), which affects the appearance of the learning machine.

[0093] As shown in Figure 13 , in the embodiment, when the driving member 13 controls the flip angle of the flip cover 12 to be 0°, based on the design of the above damping structure, it can be ensured that the side surface of the flip cover 12 facing the base 11 is attached to the base 11, that is, the camera module 1 is maintained in the closed state.

[0094] As shown in Figure 15 and Figure 16As shown, in actual application, based on the design of the damping structure, the driving member 13 can control the flip cover 12 to flip 180° relative to the base 11, or reach a flip angle greater than 180°, and can maintain the hovering state at these flip angles, ensuring the reliability of the learning machine in use, and widening the use scenarios of the learning machine.
