Description

Technical Field

[0001] This application belongs to the technical field of electronic device design, and particularly relates to an electronic module and an electronic device. Background Art

[0002] With the development of technology, electronic devices are more and more widely used. An electronic device (such as a mobile phone) usually has an electronic module, and different electronic modules have different functions, so as to enrich the functions of the electronic device. The electronic module can be an image acquisition module, so that the electronic device has a shooting function. When a user uses a mobile phone to take a picture, it is easy for the mobile phone to be unstable due to human shaking or other reasons, so that the functional components (such as a lens assembly) of the image acquisition module are likely to shift, and it is easy to cause poor image quality obtained by the mobile phone. To improve the imaging quality, it is necessary to make the functional components move more precisely to more precisely adjust the shifted functional components, so as to perform anti-shake.

[0003] The electronic module related to the related technology detects the stroke of the functional component by setting a capacitor, fixing one plate of the capacitor, and setting the other plate to move with the functional component to change the capacitance value of the capacitor, so that the functional component can move more precisely. However, in this structure, one plate of the capacitor will move with the functional component, resulting in difficulty in stably realizing electrical connection of this plate, so that the capacitor is difficult to be stably electrically connected, and further resulting in a greater design difficulty for the electronic module. Summary of the Utility Model

[0004] The utility model discloses an electronic module and an electronic device to solve the problem that the electronic module related to the related technology is difficult to stably realize the electrical connection of the capacitor, resulting in a greater design difficulty.

The first plate and the second plate are spaced apart and relatively fixed on the base, and a gap is formed therebetween. At least part of the dielectric is arranged in the gap;

[0008] The functional component can move along a preset direction. As the functional component moves, the dielectric moves along the preset direction relative to the first electrode plate and the second electrode plate, so as to change the penetration amount of the dielectric in the gap. The capacitance value of the capacitor changes with the change of the penetration amount, so as to detect the stroke of the functional component in the preset direction.

[0009] In a second aspect, the present application discloses an electronic device. The disclosed electronic device includes a housing and the above-mentioned electronic module, and the electronic module is arranged in the housing.

[0010] The technical solution adopted by the present utility model can achieve the following technical effects:

[0011] The electronic module disclosed in the embodiment of the present application improves the structure of the electronic module involved in the related art. By setting the functional component to include a dielectric, by fixing the first electrode plate of the capacitor and the second electrode plate of the capacitor at intervals and relatively on the base, and forming a gap therebetween, and by arranging at least part of the dielectric in the gap, and at the same time arranging the functional component movably on the base, the functional component can move along a preset direction, so that the dielectric can move along the preset direction relative to the first electrode plate and the second electrode plate as the functional component moves, so as to be able to change the penetration amount of the dielectric in the gap. The capacitance value of the capacitor changes with the change of the penetration amount, so as to be able to detect the stroke of the functional component in the preset direction. This structure changes the capacitance value of the capacitor by the movement of the dielectric in the gap, so that it is not necessary for the first electrode plate or the second electrode plate to move, making it easier to achieve a stable electrical connection between the first electrode plate and the second electrode plate, and further making it easier to achieve a stable electrical connection of the capacitor, which is beneficial to reducing the design difficulty of the electronic module.

[0030] Please refer to Figures 1 to 7 , this application embodiment discloses an electronic module, and the disclosed electronic module includes a base 100, a functional component 200, and a capacitor 300.

[0031] The base 100 is a basic component of the electronic module. The base 100 is used to provide an installation position for other components of the electronic module. Among them, the functional component 200, the first electrode plate 310, the second electrode plate 320, and the driving mechanism described later are all provided on the base 100. In addition, the base 100 is also used to form some functional spaces or structures, such as the stator described later.

[0032] The functional component 200 is the core component for realizing the functions of the electronic module. The capacitor 300 is used to detect the stroke of the functional component 200 in a preset direction. The functional component 200 includes a dielectric 210. The capacitor 300 includes a first electrode plate 310 and a second electrode plate 320. The first electrode plate 310 and the second electrode plate 320 are spaced apart and relatively fixed to the base 100, and a gap 330 is formed therebetween. Specifically, the capacitor 300 can be a parallel plate capacitor. The dielectric 210 is at least partially disposed in the gap 330. Specifically, the dielectric 210 can be a liquid crystal polymer or mica. The specific material of the dielectric 210 is not limited in the embodiments of this application.

[0033] The functional component 200 is movably disposed on the base 100 such that during a specific working process, the functional component 200 can move along a preset direction. As the functional component 200 moves, the dielectric 210 moves relative to the first electrode plate 310 and the second electrode plate 320 along the preset direction to change the penetration amount of the dielectric 210 in the gap 330. The capacitance value of the capacitor 300 changes with the change of the penetration amount to detect the stroke of the functional component 200 in the preset direction. That is to say, this structure changes the capacitance value of the capacitor 300 through the movement of the dielectric 210, and both the first electrode plate 310 and the second electrode plate 320 are fixed to the base 100, so that the first electrode plate 310 and the second electrode plate 320 are not arranged to be movable, avoiding the disconnection of the electrical connection between the first electrode plate 310 and the second electrode plate 320 easily caused by the movement after the electrical connection between the first electrode plate 310 and the second electrode plate 320, and thus facilitating the realization of the stable electrical connection between the first electrode plate 310 and the second electrode plate 320 to facilitate the realization of the stable electrical connection of the capacitor 300.

[0034] Specifically, when at least a part of the dielectric 210 is disposed in the gap 330, the projection of the part of the dielectric 210 extending into the gap 330 in the distribution direction of the first electrode plate 310 and the second electrode plate 320 at least partially overlaps with the projections of the first electrode plate 310 and the second electrode plate 320 in their distribution direction, so that the projections of the dielectric 210, the first electrode plate 310 and the second electrode plate 320 in the distribution direction of the first electrode plate 310 and the second electrode plate 320 have a first overlapping area.

[0035] During a specific working process, the dielectric 210 moves along the preset direction with the functional component 200, thereby changing the penetration amount. The change of the penetration amount causes the change of the first overlapping area, thereby causing the change of the capacitance value of the capacitor 300. That is to say, the capacitance value of the capacitor 300 changes with the stroke of the functional component 200 in the preset direction, so that the change of the capacitance value of the capacitor 300 corresponds to different sizes of the stroke of the functional component 200 in the preset direction respectively.

[0036] The electronic module disclosed in the embodiments of the present application improves the structure of the electronic module involved in the related art. By setting the functional component 200 to include a dielectric 210, fixing the first electrode plate 310 and the second electrode plate 320 of the capacitor 300 at intervals and oppositely on the base 100, forming a gap 330 therebetween, and at least partially disposing the dielectric 210 in the gap 330, and simultaneously disposing the functional component 200 movably on the base 100, the functional component 200 can move along a preset direction, so that the dielectric 210 can move relative to the first electrode plate 310 and the second electrode plate 320 along the preset direction as the functional component 200 moves, so as to be able to change the insertion amount of the dielectric 210 in the gap 330, and the capacitance value of the capacitor 300 changes with the change of the insertion amount, thereby being able to detect the stroke of the functional component 200 in the preset direction.

[0037] This structure changes the capacitance value of the capacitor 300 through the movement of the dielectric 210 in the gap 330, so that it is not necessary for the first electrode plate 310 or the second electrode plate 320 to move, making it easier to achieve a stable electrical connection between the first electrode plate 310 and the second electrode plate 320, and further easier to achieve a stable electrical connection of the capacitor 300, which is beneficial to reducing the design difficulty of the electronic module.

[0038] Please refer to Figure 7 , as described above, the first electrode plate 310 and the second electrode plate 320 are opposite to each other, which makes the projections of the first electrode plate 310 and the second electrode plate 320 in their distribution directions overlap with each other, so that the projections of the first electrode plate 310 and the second electrode plate 320 in their distribution directions can have a second overlapping area. The projections of the portions between the first electrode plate 310 and the second electrode plate 320 that are not inserted by the dielectric 210 in the distribution directions of the first electrode plate 310 and the second electrode plate 320 can overlap with each other, so that the projections of the portions between the first electrode plate 310 and the second electrode plate 320 that are not inserted by the dielectric 210 in the distribution directions of the first electrode plate 310 and the second electrode plate 320 can have a third overlapping area.

[0039] Meanwhile, the first electrode plate 310 and the second electrode plate 320 can have a first distance in their distribution directions, the dielectric 210 and the first electrode plate 310 can have a second distance in the distribution directions of the first electrode plate 310 and the second electrode plate 320, and the dielectric 210 and the second electrode plate 320 can have a third distance in the distribution directions of the first electrode plate 310 and the second electrode plate 320.

[0040] When the dielectric 210 is at least partially disposed in the gap 330, the dielectric 210 can be polarized. A partial area of the first electrode plate 310 overlaps with the part of the dielectric 210 extending into the gap 330 in the distribution direction of the first electrode plate 310 and the second electrode plate 320, so that a first equivalent capacitance can be formed between the first electrode plate 310 and the dielectric 210, and the first equivalent capacitance can have a first equivalent capacitance value; the polarized dielectric 210 can form a second equivalent capacitance, and the second equivalent capacitance can have a second equivalent capacitance value; a partial area of the second electrode plate 320 overlaps with the part of the dielectric 210 extending into the gap 330 in the distribution direction of the first electrode plate 310 and the second electrode plate 320, so that a third equivalent capacitance can be formed between the second electrode plate 320 and the dielectric 210, and the third equivalent capacitance can have a third equivalent capacitance value.

[0041] In addition, another partial area of the first electrode plate 310 and another partial area of the second electrode plate 320 overlap in the distribution direction of the first electrode plate 310 and the second electrode plate 320, and the projections of another partial area of the first electrode plate 310 and another partial area of the second electrode plate 320 in the distribution direction of the first electrode plate 310 and the second electrode plate 320 can be offset from the projection of the dielectric 210 in the distribution direction of the first electrode plate 310 and the second electrode plate 320, that is, the dielectric 210 does not extend between another partial area of the first electrode plate 310 and another partial area of the second electrode plate 320, and a fourth equivalent capacitance can be formed between another partial area of the first electrode plate 310 and another partial area of the second electrode plate 320, and the fourth equivalent capacitance can have a fourth equivalent capacitance value.

[0042] Optionally, the second overlapping area can be denoted as s, the first overlapping area can be denoted as s1, the third overlapping area can be denoted as s2, the first distance can be denoted as d, the second distance can be denoted as d1, the thickness of the dielectric 210 can be denoted as d2, the third distance can be denoted as d3, the capacitance value of the capacitor 300 can be denoted as C, the first equivalent capacitance value can be denoted as C1, the second equivalent capacitance value can be denoted as C2, the third equivalent capacitance value can be denoted as C3, the fourth equivalent capacitance value can be denoted as C4, the dielectric constant of the capacitor 300 can be denoted as ε0, and the dielectric constant of the dielectric 210 can be denoted as ε1.

[0043] It should be noted that the distribution direction of the first electrode plate 310 and the second electrode plate 320 can be parallel to the thickness direction of the dielectric 210.

[0044] When the dielectric 210 is at least partially disposed in the gap 330, the first equivalent capacitance, the second equivalent capacitance, and the third equivalent capacitance are connected in series, and the first equivalent capacitance, the second equivalent capacitance, and the third equivalent capacitance connected in series are connected in parallel with the fourth equivalent capacitance. This makes the capacitance value of the capacitor 300 in this case the capacitance value of the fifth equivalent capacitance formed by connecting the first equivalent capacitance, the second equivalent capacitance, and the third equivalent capacitance in series and then connecting them in parallel with the fourth equivalent capacitance.

[0045] Wherein, , , , ; .

[0046] Therefore, it can be obtained that ;

[0047] After integration, it can be obtained that .

[0048] For the convenience of recording, can be denoted as A, and can be denoted as B, that is, .

[0049] It should be noted that the dielectric 210 moves along the preset direction with the functional component 200. Therefore, the distance between the first electrode plate 310 and the second electrode plate 320 in their distribution direction, the distance between the dielectric 210 and the first electrode plate 310 in the distribution direction of the first electrode plate 310 and the second electrode plate 320, and the distance between the dielectric 210 and the second electrode plate 320 in the distribution direction of the first electrode plate 310 and the second electrode plate 320 can all remain unchanged, that is, the first distance, the second distance, and the third distance can all remain unchanged. Optionally, the thickness of the dielectric 210 can be the same in the extending direction, which makes the first distance, the second distance, the third distance, and the thickness of the dielectric 210 all constants, so that both A and B are constants.

[0050] As described above, , so the first overlapping area (i.e., s1) can be obtained based on the capacitance value of the capacitor 300 (i.e., C), where the first overlapping area is the area of the overlapping part of the dielectric 210, the first electrode plate 310, and the second electrode plate 320 projected in the distribution direction of the first electrode plate 310 and the second electrode plate 320. In the specific working process, the dielectric 210 moves along the preset direction with the functional component 200, and the penetration amount changes. The change in the penetration amount causes the first overlapping area to change, that is, different sizes of the first overlapping area respectively correspond to different sizes of the penetration amount, and different sizes of the penetration amount correspond to different sizes of the stroke of the functional component 200 in the preset direction. This enables, after obtaining different sizes of the first overlapping area based on the capacitance values of different sizes of the capacitor 300, the corresponding different sizes of the stroke of the functional component 200 in the preset direction to be obtained respectively, so that the corresponding different sizes of the stroke of the functional component 200 in the preset direction can be obtained based on the capacitance values of different sizes of the capacitor 300. That is to say, the relationship between the capacitance value of the capacitor 300 and the stroke of the functional component 200 in the preset direction can be obtained through the above calculation model. Determining the stroke of the functional component 200 in the preset direction according to the magnitude of the capacitance value of the capacitor 300 is not the inventive point of this application and will not be elaborated here.

[0051] In the embodiment of the present application, the electronic module can be an image acquisition module. Correspondingly, the functional component 200 can be a lens module. The electronic module can also include a driving mechanism. The driving mechanism can be arranged on the base 100 and connected to the lens module for driving the lens module to move along the preset direction, so as to be able to automatically drive the lens module to move, which is beneficial to improving the automation degree of the image acquisition module, and the driving mechanism can drive the lens module to move more precisely, and the driving mechanism can quickly respond and thus drive the lens module to move efficiently.

[0052] Of course, the electronic module can also include a manual driving part. The manual driving part can be arranged on the base 100 and connected to the lens module for manually driving the lens module to move along the preset direction through the manual driving part. This structure is relatively simple and easy to implement, and is beneficial to reducing the cost of the electronic module.

[0053] In one embodiment, the capacitor 300 can include a first sub-capacitor 301. The first sub-capacitor 301 can include a first sub-electrode plate 311 of the first electrode plate 310 and a second sub-electrode plate 321 of the second electrode plate 320. The dielectric 210 can include a first sub-dielectric 211. The preset direction can include a first direction. The gap 330 can include a first sub-gap 331.

[0054] The first sub-plate 311 and the second sub-plate 321 can be fixedly arranged on the base 100 at intervals and opposite to each other, and a first sub-gap 331 can be formed therebetween. In this case, the first sub-capacitor 301 can be a parallel-plate capacitor. The first dielectric 211 can be at least partially arranged in the first sub-gap 331. Specifically, the first dielectric 211 can be a liquid crystal polymer or mica. The embodiments of the present application do not limit the specific material of the first dielectric 211.

[0055] The driving mechanism can be used to drive the lens assembly to move along the first direction for anti-shake movement. The first dielectric 211 can move along the first direction relative to the first sub-plate 311 and the second sub-plate 321 as the lens assembly moves, so as to change the first penetration amount of the first dielectric 211 in the first sub-gap 331. The capacitance value of the first sub-capacitor 301 can change with the change of the first penetration amount, so as to detect the stroke of the lens assembly in the first direction, so that the lens assembly can perform anti-shake movement in the first direction more accurately.

[0056] Specifically, when the first dielectric 211 is arranged in the first sub-gap 331, the projection of the part of the first dielectric 211 extending into the first sub-gap 331 in the distribution direction of the first sub-plate 311 and the second sub-plate 321 can overlap with the projection of the first sub-plate 311 and the second sub-plate 321 in their distribution direction, so that the projections of the first dielectric 211, the first sub-plate 311 and the second sub-plate 321 in the distribution direction of the first sub-plate 311 and the second sub-plate 321 can have a first overlapping area.

[0057] In the specific working process, the first dielectric 211 can move along the first direction with the lens assembly, so as to change the first penetration amount. The change of the first penetration amount causes the change of the first overlapping area, so that the capacitance value of the first sub-capacitor 301 changes. That is to say, the capacitance value of the first sub-capacitor 301 can change with the stroke of the lens assembly in the first direction, so that the change of the capacitance value of the first sub-capacitor 301 can respectively correspond to different stroke sizes of the lens assembly in the first direction. Similarly, the relationship between the capacitance value of the first sub-capacitor 301 and the stroke of the lens assembly in the first direction can be obtained through the calculation model as described above, and this part will not be elaborated here.

[0058] In an alternative technical solution, the base 100 may be provided with a first mounting hole 101. The first mounting hole 101 may be a rectangular hole. The first sub-plate 311 and the second sub-plate 321 may be respectively disposed on two opposite hole walls of the first mounting hole 101, so that the first sub-plate 311 and the second sub-plate 321 can be fixedly arranged opposite to and spaced from each other on the base 100. In this case, the first sub-gap 331 may be located in the first mounting hole 101, and the first sub-dielectric 211 may be at least partially disposed in the first sub-gap 331 in the first mounting hole 101. This structure can make full use of the base 100, avoid additionally providing a mounting portion for the first sub-capacitor 301, is beneficial to cost saving, and can avoid wasting space due to additionally providing a mounting portion for the first sub-capacitor 301.

[0059] In a further technical solution, the capacitor 300 may further include a second sub-capacitor 302. The second sub-capacitor 302 may include a third sub-plate 312 of the first plate 310 and a fourth sub-plate 322 of the second plate 320. The dielectric 210 may further include a second sub-dielectric 212. The preset direction may further include a second direction. The gap 330 may further include a second sub-gap 332. It should be noted that the first direction may be perpendicular to the second direction.

[0060] The third sub-plate 312 and the fourth sub-plate 322 may be fixedly arranged opposite to and spaced from each other on the base 100, and a second sub-gap 332 may be formed therebetween. In this case, the second sub-capacitor 302 may be a parallel plate capacitor. The second sub-dielectric 212 may be at least partially disposed in the second sub-gap 332. Specifically, the second sub-dielectric 212 may be a liquid crystal polymer or mica. The present application embodiment does not limit the specific material of the second sub-dielectric 212.

[0061] The driving mechanism may be used to drive the lens assembly to move along the second direction for anti-shake movement. The second sub-dielectric 212 may move along the second direction relative to the third sub-plate 312 and the fourth sub-plate 322 as the lens assembly moves, so as to change the second insertion amount of the second sub-dielectric 212 in the second sub-gap 332. The capacitance value of the second sub-capacitor 302 may change with the change of the second insertion amount, so as to detect the stroke of the lens assembly in the second direction. This structure enables the lens assembly to perform anti-shake movement in the first direction and the second direction more accurately, so as to perform anti-shake movement more effectively, and better improve the quality of the image obtained by the image acquisition module.

[0062] Specifically, when the second sub-dielectric 212 is disposed in the second sub-gap 332, the projection of the portion of the second sub-dielectric 212 extending into the second sub-gap 332 in the distribution direction of the third sub-plate 312 and the fourth sub-plate 322 can overlap with the projections of the third sub-plate 312 and the fourth sub-plate 322 in their distribution direction, so that the projections of the second sub-dielectric 212, the third sub-plate 312 and the fourth sub-plate 322 in the distribution direction of the third sub-plate 312 and the fourth sub-plate 322 can have a second overlapping area.

[0063] During the specific working process, the second sub-dielectric 212 can move along the second direction with the lens assembly, thereby changing the second sub-extension amount. The change of the second sub-extension amount causes the change of the second overlapping area, thereby causing the change of the capacitance value of the second sub-capacitor 302. That is to say, the capacitance value of the second sub-capacitor 302 can change with the stroke of the lens assembly in the second direction, so that the change of the capacitance value of the second sub-capacitor 302 can respectively correspond to different sizes of strokes of the lens assembly in the second direction. Similarly, the relationship between the capacitance value of the second sub-capacitor 302 and the stroke of the lens assembly in the second direction can be obtained through the calculation model as described above, and this part will not be elaborated here.

[0064] Optionally, the base 100 can be provided with a second mounting hole 102. The second mounting hole 102 can be a rectangular hole. The third sub-plate 312 and the fourth sub-plate 322 can be respectively disposed on two opposite hole walls of the second mounting hole 102, so that the third sub-plate 312 and the fourth sub-plate 322 can be fixed to the base 100 relatively and at intervals. In this case, the second sub-gap 332 can be located in the second mounting hole 102, and the second sub-dielectric 212 can be at least partially disposed in the second sub-gap 332 in the second mounting hole 102. This structure can make full use of the base 100, avoid additionally setting an installation part for the second sub-capacitor 302, is beneficial to cost saving, and can avoid wasting space by additionally setting an installation part for the second sub-capacitor 302.

[0065] In a further technical solution, the capacitor 300 can further include a third sub-capacitor 303. The third sub-capacitor 303 can include a fifth sub-plate 313 of the first plate 310 and a sixth sub-plate 323 of the second plate 320. The dielectric 210 can further include a third sub-dielectric 213. The preset direction can further include a third direction. The gap 330 can further include a third sub-gap.

[0066] The fifth sub-plate 313 and the sixth sub-plate 323 can be fixedly arranged on the base 100 at intervals and oppositely, and a third sub-gap can be formed therebetween. In this case, the third sub-capacitor 303 can be a parallel-plate capacitor. The third sub-dielectric 213 can be at least partially arranged in the third sub-gap. Specifically, the third sub-dielectric 213 can be a liquid crystal polymer or mica. The embodiments of the present application do not limit the specific material of the second sub-dielectric 212.

[0067] The driving mechanism can be used to drive the lens module to move along the third direction for anti-shake movement. The third sub-dielectric 213 can move relative to the fifth sub-plate 313 and the sixth sub-plate 323 along the third direction as the lens module moves, so as to change the third sub-insertion amount of the third sub-dielectric 213 in the third sub-gap. The capacitance value of the third sub-capacitor 303 can change with the change of the third sub-insertion amount, so as to detect the stroke of the lens module in the third direction. This structure enables the lens module to perform anti-shake movement in the third direction more accurately, so as to further reduce shake during shooting and improve the quality of the image obtained by the image acquisition module.

[0068] It should be noted that the third direction can be perpendicular to the first direction and the second direction respectively. Optionally, one of the first direction, the second direction and the third direction can be parallel to the optical axis of the lens module, and the other two can be parallel to each other and perpendicular to the optical axis of the lens module respectively. When the driving mechanism drives the lens module to move along one of the first direction, the second direction and the third direction that is parallel to the optical axis of the lens module, focusing can be achieved. This structure is beneficial for the image acquisition module to achieve more accurate focusing, thereby improving the quality of the image obtained by the image acquisition module.

[0069] Specifically, when the third sub-dielectric 213 is arranged in the third sub-gap 333, the projection of the part of the third sub-dielectric 213 extending into the third sub-gap 333 in the distribution direction of the fifth sub-plate 313 and the sixth sub-plate 323 can overlap with the projection of the fifth sub-plate 313 and the sixth sub-plate 323 in their distribution direction, so that the projections of the third sub-dielectric 213, the fifth sub-plate 313 and the sixth sub-plate 323 in the distribution direction of the fifth sub-plate 313 and the sixth sub-plate 323 can have a third overlapping area.

[0070] In the specific working process, the third sub-dielectric 213 can move along the third direction with the lens assembly, thereby changing the third sub-insertion amount. The change in the third sub-insertion amount causes the change in the third sub-overlap area, thereby changing the capacitance value of the third sub-capacitor 303. That is to say, the capacitance value of the third sub-capacitor 303 can change with the stroke of the lens assembly in the third direction, so that the change in the capacitance value of the third sub-capacitor 303 can respectively correspond to different sizes of the stroke of the lens assembly in the third direction. Similarly, the relationship between the capacitance value of the third sub-capacitor 303 and the stroke of the lens assembly in the third direction can be obtained through the calculation model described above, and this part will not be elaborated here.

[0071] In an alternative technical solution, the base 100 may be provided with a first mounting groove 103. The fifth sub-plate 313 and the sixth sub-plate 323 may be respectively disposed on two opposite groove walls of the first mounting groove 103, so that the fifth sub-plate 313 and the sixth sub-plate 323 can be fixed to the base 100 relatively and at intervals. In this case, the third sub-gap 333 may be located in the first mounting groove 103, and the third sub-dielectric 213 may be at least partially disposed in the third sub-gap 333 in the first mounting groove 103. This structure can make full use of the base 100, avoid additionally providing a mounting portion for the third sub-capacitor 303, is beneficial to cost saving, and can avoid wasting space by additionally providing a mounting portion for the third sub-capacitor 303.

[0072] In one technical solution, the capacitor 300 may further include a fourth sub-capacitor. The fourth sub-capacitor may include a seventh sub-plate of the first plate 310 and an eighth sub-plate of the second plate 320. The dielectric 210 may further include a fourth sub-dielectric, the gap 330 may further include a fourth sub-gap, and the preset direction may further include a fourth direction. The fourth direction may be a circumferential direction around the optical axis of the lens assembly. That is to say, the lens assembly rotates along the fourth direction.

[0073] The seventh sub-plate and the eighth sub-plate may be fixed to the base 100 at intervals and relatively, and a fourth sub-gap may be formed therebetween. Specifically, the fourth sub-capacitor may be a parallel plate capacitor. The fourth sub-dielectric may be at least partially disposed in the fourth sub-gap. Specifically, the material of the fourth sub-dielectric may be liquid crystal polymer or mica, and the embodiments of the present application do not limit this.

[0074] The driving mechanism can be used to drive the lens assembly to perform anti-shake rotation along the fourth direction. The fourth sub-dielectric can rotate relative to the seventh sub-plate and the eighth sub-plate along the fourth direction as the lens assembly rotates, so as to change the fourth sub-insertion amount of the fourth sub-dielectric in the fourth sub-gap. The capacitance value of the fourth sub-capacitor can change with the change of the fourth sub-insertion amount, so as to detect the stroke of the lens assembly in the fourth direction, so that the lens assembly can move accurately in the fourth direction, that is, the lens assembly can rotate accurately around the optical axis of the lens assembly.

[0075] Specifically, when the fourth sub-dielectric is arranged in the fourth sub-gap, the projection of the part of the fourth sub-dielectric extending into the fourth sub-gap in the distribution direction of the seventh sub-plate and the eighth sub-plate can overlap with the projection of the seventh sub-plate and the eighth sub-plate in their distribution direction, so that the projections of the fourth sub-dielectric, the seventh sub-plate and the eighth sub-plate in the distribution direction of the seventh sub-plate and the eighth sub-plate can have a fourth overlapping area.

[0076] In the specific working process, the fourth sub-dielectric can move along the fourth direction with the lens assembly, so as to change the fourth sub-insertion amount. The change of the fourth sub-insertion amount causes the change of the fourth overlapping area, so that the capacitance value of the fourth sub-capacitor changes. That is to say, the capacitance value of the fourth sub-capacitor can change with the stroke of the lens assembly in the fourth direction, so that the change of the capacitance value of the fourth sub-capacitor can respectively correspond to different sizes of strokes of the lens assembly in the fourth direction. Similarly, the relationship between the capacitance value of the fourth sub-capacitor and the stroke of the lens assembly in the fourth direction can be obtained through the calculation model described above, and this part will not be elaborated here.

[0077] In a further technical solution, both the fourth sub-capacitor and the fourth sub-dielectric can be multiple. The multiple fourth sub-dielectrics can all be arc-shaped dielectrics, and the multiple seventh sub-plates and the multiple eighth sub-plates can all be arc-shaped plates. The multiple seventh sub-plates and the multiple eighth sub-plates can be fixedly arranged at intervals around the circumferential direction of the optical axis of the lens assembly on the base 100. The multiple seventh sub-plates can be respectively distributed at intervals and oppositely to the multiple eighth sub-plates to form multiple fourth sub-gaps distributed around the circumferential direction of the optical axis of the lens assembly and spaced from each other, and the multiple fourth sub-gaps can all be arc-shaped gaps, so that the multiple fourth sub-dielectrics can all move smoothly along the fourth direction in the multiple fourth sub-gaps.

[0078] A plurality of fourth sub-dielectrics can be respectively disposed at least partially in a plurality of fourth sub-gaps. The plurality of fourth sub-dielectrics can all be used to change the fourth sub-insertion amount of the plurality of fourth sub-dielectrics in the plurality of fourth sub-gaps as the lens assembly rotates. After each fourth sub-dielectric leaves the corresponding fourth sub-gap along the fourth direction, it can enter the adjacent fourth sub-gap, avoiding the situation that all the fourth sub-dielectrics are located in the fourth sub-gap or all are located outside the fourth sub-gap, which can easily lead to the capacitance value of the fourth sub-capacitor no longer changing, thereby avoiding the situation that it is difficult to accurately detect the stroke of the lens assembly in the fourth direction, and further being beneficial to improving the reliability of the image acquisition module.

[0079] In an embodiment of the present application, the driving mechanism can include a coil and a magnetic member. The coil can be fixed to the base 100, the magnetic member can be fixed to the lens assembly, the coil can be opposite to the magnetic member, and can be used to drive the lens assembly to move along a preset direction through the magnetic member. In this structure, the coil and the magnetic member do not need to contact, thereby reducing the wear between the two, being beneficial to extending the service life of the driving mechanism, and enabling the driving mechanism to have less noise during operation, being beneficial to realizing the quiet operation of the image acquisition module, and thus being beneficial to improving the user experience.

[0080] When the lens assembly can perform anti-shake movements along the first direction, the second direction, and the third direction, the coil can include a first sub-coil 410, a second sub-coil 420, and a third sub-coil 430, the magnetic member can include a first sub-magnetic member, a second sub-magnetic member, and a third sub-magnetic member.

This structure can reduce the friction between the lens holder 240 and the first carrier 610 through the rolling element 630, thereby reducing the wear of the lens holder 240 and the first carrier 610, which is beneficial to extending the service life of the lens holder 240 and the first carrier 610.

This structure can reduce the friction between the first carrier 610 and the second carrier 620 through the rolling element 630, thereby reducing the wear of the first carrier 610 and the second carrier 620, which is beneficial to extending the service life of the first carrier 610 and the second carrier 620.

[0085] In addition, a rolling element 630 may be provided between the second carrier 620 and the base 100, and the second carrier 620 can move relative to the base 100 along a third direction, so as to be able to drive the lens 230 to move along the third direction through the first carrier 610 and the lens holder 240.
