[0002] At present, most mobile terminal cameras support auto focus function. When using the auto focus function to take photos, the camera can automatically focus and track according to different shooting objects, so as to ensure that the focus of the photos taken is correct and the pictures are clear. Among them, the main principle of camera auto focus is to adjust the position of the camera lens according to the current scene, so the position of the camera lens in the mobile terminal is not fixed.

[0003] However, when the camera is not needed, shaking of the mobile terminal may cause the components in the camera to collide with each other, generating abnormal noise. Summary of the invention

[0031] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0032] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0033] In actual applications, when the camera is in working state, the autofocus mode is usually turned on. At this time, the position of the camera lens module needs to be adjusted according to the current scene to ensure that the focus of the photo is correct and the picture is clear. The position adjustment here refers to adjusting the relative position of the lens and other structures of the camera (such as sensors). When the camera is in standby state, the lens module does not need to be adjusted, but the components in the lens module are still in a free state, and their position relationship is unstable.

[0034] Therefore, if Figure 1 As shown, an embodiment of the present invention provides a camera 100 and exemplarily shows the structure of the camera 100 when it is in a standby state to solve the above-mentioned problems.

[0035] Figure 1In the embodiment, the camera 100 includes a camera assembly 10, a transmission mechanism 20 and a support frame 30; the support frame 30 has a first side 31 ( Figure 2 The second side edge 32 ( Figure 2 The third side 33 ( Figure 2 ) and the fourth side 34 ( Figure 2 The transmission mechanism 20 is placed on any side of the support frame 30 , and the camera assembly 10 is placed in the support frame 30 and extends out from the first side 31 of the support frame 30 .

[0036] It is understandable that, in the camera assembly 10 , the portion extending from the first side 31 of the supporting frame 30 is the lens module 11 .

[0037] In the embodiment of the present invention, when the camera 100 is in the standby state, the transmission mechanism 20 extends along the direction from the support frame 30 to the camera assembly 10 until the transmission mechanism 20 abuts against the camera assembly 10 .

[0038] In a specific application, after the transmission mechanism 20 abuts against the camera assembly 10, the position of the camera assembly 10 is fixed, and the components in the camera assembly 10 are usually connected to each other. Therefore, when the mobile terminal shakes, not only will the components in the camera assembly 10 no longer collide with each other, but the camera assembly 10 will also not collide with the support frame 30, thereby effectively solving the problem of the components in the camera 100 colliding with each other and generating abnormal noises.

[0039] The camera provided in the embodiment of the present invention, when the camera function is not turned on, fixes the camera assembly on the support frame through a transmission mechanism, so that the position of the internal structure of the camera is fixed, effectively solving the problem of collision and abnormal noise between the inside of the camera assembly and between the camera assembly and the support frame, while reducing the wear of the camera and increasing its service life.

[0040] like Figure 2 As shown, the embodiment of the present invention also shows the detailed structure of the camera assembly 10 to explain the above in detail. Figure 1 The structure of the camera 100, Figure 2 In the figure, the camera assembly 10 includes a lens module 11 and a lens mover module 12.

[0041] The lens mover module 12 includes a first motor mover 121 and a second motor mover 122 , and the first motor mover 121 and the second motor mover 122 are arranged on the peripheral side surface of the lens module 11 .

[0042] like Figure 1 and Figure 2As shown, after the transmission mechanism 20 extends along the direction from the support frame 30 to the camera assembly 10 , the abutment between the transmission mechanism 20 and the camera assembly 10 can be manifested as abutment with the first motor mover 121 , or abutment with the second motor mover 122 .

[0043] or Figure 3 As shown, there are two transmission mechanisms 20. After extending along the direction from the support frame 30 to the camera assembly 10, the abutment between the transmission mechanism 20 and the camera assembly 10 can be manifested as the two transmission mechanisms 20 abutting against the first motor mover 121 and the second motor mover 122 respectively.

[0044] In one embodiment, one end of the transmission mechanism 20 away from the support frame 30 also matches the contact surface of the first motor mover 121 or the second motor mover 122 .

[0045] For example: when the transmission mechanism 20 contacts the first motor mover 121 and the contact surface of the first motor mover 121 has a groove, the shape of the end of the transmission mechanism 20 away from the support frame 30 can be rectangular; when the contact surface of the first motor mover 121 has a small gap, the shape of the end of the transmission mechanism 20 away from the support frame 30 can be conical.

[0046] By matching the shape of one end of the transmission mechanism 20 with the contact surface of the first motor mover 121 or the contact surface of the second motor mover 122 , the structural reliability of the transmission mechanism 20 after abutting against the first motor mover 121 or the transmission mechanism 20 and the second motor mover 122 is increased.

[0047] Figure 2 In the figure, the first reed 40 and the second reed 50 are also fixed to the support frame 30. One end of the first reed 40 and the second reed 50 are respectively fixed to the second side 32 and the third side 33 of the support frame 30, and the other ends of the first reed 40 and the second reed 50 are also respectively connected to the first motor mover 121 and the second motor mover 122; wherein the second side 32 and the third side 33 are adjacent to the first side 31. It can be seen that the position of the camera assembly 10 in the support frame 30 is not fixed and has a certain degree of mobility.

[0048] In the embodiment of the present invention, the lens mover module 12 is used to provide power for position adjustment in the entire camera assembly 10, wherein the first motor mover 121 and the second motor mover 122 are the parts of the lens mover module 12 that are directly connected to the lens module 11, and the first reed 40 and the second reed 50 are the parts that connect the support frame 30 and the lens module 11. Figure 2It can be seen from the structure of the camera 100 shown that the first motor mover 121 and the second motor mover 122 are key parts for moving the lens module 11. When the transmission mechanism 20 abuts against the first motor mover 121 or the second motor mover 122, or when the two transmission mechanisms 20 abut against the first motor mover 121 and the second motor mover 122 respectively, the first motor mover 121 and the second motor mover 122 are fixed on the support frame 30, which is equivalent to the lens module 11 being fixed on the support frame 30. Therefore, when the mobile terminal shakes, the lens module 11 will not collide with other structures located in the support frame 30, and the first motor mover 121 and the second motor mover 122 will not collide with the support frame 30, thereby generating abnormal noise.

[0049] In a specific application, the two transmission mechanisms 20 are respectively in contact with the first motor mover 121 and the second motor mover 122 , so that the stability of the first motor mover 121 , the second motor mover 122 and the lens module 11 on the support frame 30 can be increased.

[0050] It is understandable that the camera assembly 10 not only includes the lens module 11 and the lens mover module 12, but also has other structures, such as an infrared sensor, a vibration motor, etc. In the embodiment of the present invention, the support frame 30 can also be a part of the camera assembly 10, such as the frame of the vibration motor, wherein the extension or contraction of the transmission mechanism 20 is controlled by the mobile terminal alone and has nothing to do with the lens mover module 12.

[0051] In one embodiment, when the first motor mover 121 and the second motor mover 122 are arranged on the peripheral side of the lens module 11, the positions of the first motor mover 121 and the second motor mover 122 are relative, that is, the distance from the first motor mover 121 to the second motor mover 122 is the width of the lens module 11 in the direction from the second side 32 to the third side 33. When the two transmission mechanisms 20 are respectively in contact with the first motor mover 121 and the second motor mover 122, the stability of the first motor mover 121, the second motor mover 122 and the lens module 11 on the support frame 30 is increased.

[0052] In the embodiment of the present invention, the detailed abutment position between the transmission mechanism 20 and the first motor mover 121 and the second motor mover 122 is not limited, and the abutment position can be any position that can fix the first motor mover 121 and the second motor mover 122 on the support frame 30, such as the top, bottom or middle position of the first motor mover 121 and the second motor mover 122. In the embodiment of the present invention, the above Figure 2 and Figure 3 The structure of the transmission mechanism 20 abutting against the bottom of the first motor mover 121 is only shown as an example. Figure 4The figure only exemplarily shows a structure in which the transmission mechanism 20 is arranged in the support frame 30 and is opposite to the bottom position of the first motor mover 121 .

[0053] like Figure 1 and Figure 4 As shown, the embodiment of the present invention is based on Figure 2 The structure of the camera 100 shown is an exemplary structure of the camera 100 when it is in working state. Figure 4 In the embodiment, the transmission mechanism 20 contracts along the direction from the camera assembly 10 to the supporting frame 30, and the lens module 11 and the lens mover module 12, that is, the lens module 11, the first motor mover 121 and the second motor mover 122, are all in a free state. At this time, according to the autofocus instruction of the mobile terminal, the first motor mover 121 and the second motor mover 122 adjust the position of the lens module 11 to change the relative position of the lens module 11 and other structures (such as sensors) of the camera 100, and finally realize autofocus.

[0054] In the embodiment of the present invention, after the transmission mechanism 20 contracts in the direction from the camera assembly 10 to the support frame 30 , the end of the transmission mechanism 20 away from the support frame 30 returns to the shape before the transmission mechanism 20 abuts against the camera assembly 10 .

[0055] In a specific application, the transmission mechanism may be made of any material with deformation properties, and the embodiment of the present invention does not specifically limit it.

[0056] In one embodiment, the constituent material of the transmission mechanism may be a shape memory alloy, which, after physical deformation, is processed to restore to the state before deformation, thereby producing a shape memory effect. Exemplarily, in an embodiment of the present invention, when the camera is in a standby state, the transmission mechanism is not powered on, and the transmission mechanism is in a cooling state, i.e., a released state, so that it can extend in the direction from the support frame to the camera assembly until the transmission mechanism abuts against the camera assembly. When the camera is in a standby state, the transmission mechanism is powered on, and the transmission mechanism is in a heating state, i.e., a contracted state, so that it can contract in the direction from the camera assembly to the support frame, and the camera assembly is in a free state at this time, so as to achieve automatic focusing.

[0057] An embodiment of the present invention further provides an electronic device, which includes: Figures 1 to 4 Any of the camera structures shown.

[0058] like Figure 5 As shown, an embodiment of the present invention further provides a camera control method, the camera includes a camera assembly and a support frame fixed with a transmission mechanism, the method includes but is not limited to the following steps:

[0059] S501, obtaining the working status of the camera;

[0060] S502: If the camera is in a standby state, control the transmission mechanism to extend along the direction from the support frame to the camera assembly until the transmission mechanism abuts against the camera assembly.

[0061] In the above step S502, after the transmission mechanism abuts against the camera assembly, the position of the camera assembly is fixed, and the components in the camera assembly are usually connected. Therefore, when the mobile terminal shakes, not only will the components in the camera assembly no longer collide with each other, but the camera assembly will also not collide with the supporting frame, which effectively prevents the components in the camera from colliding with each other and generating abnormal noises.

[0062] In the above step S501, the working state of the camera can be obtained by checking whether the driving unit in the camera powers on the camera assembly, such as:

[0063] Detect the power-on status of the drive unit;

[0064] If the driving unit powers on the camera assembly, the camera is in a working state;

[0065] If the driving unit does not power on the camera assembly, the camera is in a standby state.

[0066] In a specific application, after the transmission mechanism extends from the support frame to the camera assembly and the camera assembly abuts, if the driving unit powers on the camera assembly, the transmission mechanism can be controlled to contract from the camera assembly to the support frame at the moment the camera is powered on. At this time, the camera assembly can move normally. Figures 2 to 4 The lens module, the first motor mover and the second motor mover are in a free state.

[0067] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the foregoing embodiments describe the present invention in detail, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or replace some of the technical features therein by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
