However, the buffer component in the related art has limited buffering effect on the carrier. When the carrier weight is large or is subjected to a large external force, the camera motor still produces obvious noise. Therefore, how to further improve the buffering effect on the carrier becomes a problem to be solved. SUMMARY

[0041] The driving motor, camera module and electronic device according to some embodiments of the present application will be described below with reference to FIGS. 1-23.

[0042] Embodiments of the present application provide a driving motor, as shown in FIG. 1 and FIG. 2, the driving motor 10 comprises a housing 100, a carrier 200, a first damping assembly 300 and a second damping assembly 400. The carrier 200 is located in the housing 100, and the carrier 200 is used to carry a lens, and the carrier 200 can move relative to the housing 100 along a first direction Z. The number of the first damping assembly 300 and the second damping assembly 400 is at least one, the first damping assembly 300 is arranged on the housing 100, and the first damping assembly 300 is arranged on opposite sides of the housing 100 along the first direction Z, and the first damping assembly 300 protrudes into the housing 100. The second damping assembly 400 is arranged on the carrier 200, and the second damping assembly 400 is arranged on one side of the carrier 200 and / or the other side of the carrier 200 along the first direction Z, and the second damping assembly 400 protrudes from the outer surface of the carrier 200, and the second damping assembly 400 faces the first damping assembly 300.

[0043] In this embodiment, the lens is used to be mounted on the carrier 200, and the carrier 200 is usually wrapped by magnetic force, so as to be in a suspended state. The carrier 200 is located in the housing 100, and the driving assembly can drive the carrier 200 to move relative to the housing 100, so as to realize the adjustment of the position of the lens.

[0044] The carrier 200 can move relative to the housing 100 along the first direction Z, as shown in FIG. 2, the direction indicated by the arrow at Z is the first direction Z, and the first direction Z is the optical axis direction of the lens. When the carrier 200 drives the lens to move along the first direction Z, the driving motor 10 can realize the focusing function.

[0045] Along the first direction Z, the first damping assembly 300 is arranged on opposite sides of the housing 100, and the first damping assembly 300 protrudes into the housing 100, that is, the first damping assembly 300 is arranged on the upper and lower sides of the inner wall of the housing 100, and the first damping assembly 300 is located between the carrier 200 and the housing 100. The first damping assembly 300 can play a buffering role for the carrier 200, so as to avoid the direct contact between the carrier 200 and the housing 100, thereby preventing the direct collision between the carrier 200 and the housing 100, and reducing the abnormal sound generated when colliding.

[0046] Along the first direction Z, one side of the carrier 200 and / or the other side of the carrier 200 is provided with a second shock absorption assembly 400 protruding from the outer surface of the carrier 200, the second shock absorption assembly 400 is located between the carrier 200 and the shell 100, and the second shock absorption assembly 400 is arranged opposite to the first shock absorption assembly 300, that is, the second shock absorption assembly 400 faces the first shock absorption assembly 300. When the carrier 200 moves in the shell 100 along the first direction Z, the second shock absorption assembly 400 can flexibly abut the first shock absorption assembly 300, and together hinder the direct collision between the carrier 200 and the shell 100, so as to improve the buffering protection effect between the carrier 200 and the shell 100 along the first direction Z, and improve the effect of reducing collision noise, and prolong the service life of the driving motor 10.

[0047] In the embodiment, the shell 100 and the carrier 200 are both provided with shock absorption structures, and when the carrier 200 moves in the shell 100, a soft-to-soft collision is formed between the shell 100 and the carrier 200, thereby realizing a maximized shock absorption and buffering effect. Even if the carrier 200 is heavy or the driving motor 10 is subjected to a large external force, the first shock absorption assembly 300 and the second shock absorption assembly 400 can effectively play a buffering effect and prevent the driving motor 10 from emitting noise.

[0048] The soft-to-soft impact buffering structure in the embodiment has a larger buffering and shock absorption space, and the comprehensive effect can reduce noise by 10 dB to 20 dB.

[0049] Exemplarily, the number of the first shock absorption assembly 300 and the second shock absorption assembly 400 can be multiple, the first shock absorption assembly 300 is distributed along the circumference of the shell 100, the second shock absorption assembly 400 is distributed along the circumference of the carrier 200, and the first shock absorption assembly 300 and the second shock absorption assembly 400 are uniformly distributed and have the same number, for example, the number of the first shock absorption assembly 300 and the second shock absorption assembly 400 is 4, of course, in other embodiments, the number of the first shock absorption assembly 300 and the second shock absorption assembly 400 is not limited to 4.

[0050] In some embodiments provided in the application, in combination with FIGS. 1 and 2, optionally, the first shock absorption assembly 300 includes a first shock absorption piece 310 and a second shock absorption piece 320. The shell 100 includes a base 110 and an outer shell 120. The first shock absorption piece 310 is arranged on the side of the base 110 facing the carrier 200, and the carrier 200 can move relative to the base 110 along the first direction Z. The outer shell 120 is sleeved on the base 110, the carrier 200 is located between the base 110 and the outer shell 120, and the second shock absorption piece 320 is arranged on the side of the outer shell 120 facing the carrier 200.

[0051] In this embodiment, the shell 120 is arranged on the base 110, and the shell 120 can be bonded or fixed to the base 110 by a connector, for example. The shell 120 and the base 110 form a containing space, and the carrier 200 is located in the containing space, and the carrier 200 can move in the first direction Z in the containing space.

[0052] The first damping member 310 is arranged on the base 110, and the first damping member 310 is located between the carrier 200 and the base 110. When the carrier 200 moves towards the base 110, the first damping member 310 buffers the carrier 200, avoiding the carrier 200 directly impacting the base 110.

[0053] The second damping member 320 is arranged on the shell 100, and the second damping member 320 is located between the carrier 200 and the shell 100. When the carrier 200 moves towards the shell 100, the second damping member 320 buffers the carrier 200, avoiding the carrier 200 directly impacting the shell 100.

[0054] Along the first direction Z, one side or both sides of the carrier 200 are provided with the second damping assembly 400, for example, the side of the carrier 200 facing the carrier 200 is provided with the second damping assembly 400, or the side of the carrier 200 facing the shell 100 is provided with the second damping assembly 400. Alternatively, the side of the carrier 200 facing the carrier 200 and the side of the carrier 200 facing the shell 100 are both provided with the second damping assembly 400.

[0055] When the first damping member 310 and the second damping assembly 400 are opposite, a soft-to-soft buffer structure is formed between the carrier 200 and the base 110. When the second damping member 320 and the second damping assembly 400 are opposite, a soft-to-soft buffer structure is formed between the carrier 200 and the shell 100.

[0056] The first damping member 310 and the second damping member 320 are made of an elastic material capable of buffering impact, and the first damping member 310 and the second damping member 320 can be TPU (Thermoplastic polyurethanes), TPE (Thermoplastic rubber), or silicone material, for example.

[0057] In some embodiments provided in the present application, as shown in FIGS. 2, 3, 4, 5 and 6, optionally, the base 110 is provided with a first mounting hole 111, and the drive motor 10 further comprises a first metal piece 510 connected with the base 110, a part of the first metal piece 510 extends into the first mounting hole 111, the part of the first metal piece 510 extending into the first mounting hole is connected with the first damping piece 310, a part of the first damping piece 310 is located in the first mounting hole 111, and another part of the first damping piece 310 extends out of the first mounting hole 111 towards the carrier 200.

[0058] In this embodiment, the first damping piece 310 is usually installed by injection molding process, however, the structure on the base 110 is complex, and the base 110 is usually provided with other components in the drive motor 10, therefore, the installation space on the base 110 is limited, and it is difficult to inject the first damping piece 310 on the base 110.

[0059] Therefore, when installing the first damping piece 310, the first damping piece 310 is pre-installed on the first metal piece 510, that is, before the first damping piece 310 is installed into the base 110, the first damping piece 310 is injected on the first metal piece 510 externally, at this time, the injection process of the first damping piece 310 is not limited by the space in the base 110.

[0060] The first damping piece 310 and the first metal piece 510 form an assembly, and the above assembly is installed on the base 110, the first metal piece 510 can be fixed on the base 110 by welding or bonding, the installation mode of the first metal piece 510 is simple, thereby improving the convenience of installing the first damping piece 310 on the base 110.

[0061] The base 110 is provided with the first mounting hole 111, at least a part of the first damping piece 310 is located in the first mounting hole 111, and another part of the first damping piece 310 protrudes out of the base 110 towards the carrier 200, so that the first damping piece 310 can hinder the carrier 200 from contacting the base 110, the first mounting hole 111 provides a space for the first damping piece 310 to deform, improves the deformation amount of the first damping piece 310, and further improves the buffering effect of the first damping piece 310 on the carrier 200.

[0062] The first metal piece 510 can be supported in the first mounting hole 111, or the first metal piece 510 is installed outside the first mounting hole 111, and the first metal piece 510 is bent so that a part of the first metal piece 510 extends into the first mounting hole 111.

[0063] Of course, in other embodiments, the first damping piece 310 can be directly injected on the base 110.

[0064] In some embodiments provided in the present application, as shown in FIG. 6, optionally, the first damping member 310 is provided with a first hollow cavity 311, the first hollow cavity 311 has an opening 315, the opening 315 is located on the side of the first damping member 310 away from the carrier 200, and the first hollow cavity 311 is located in the first mounting hole 111.

[0065] In this embodiment, when the first damping member 310 deforms, the first hollow cavity 311 provides space for the deformation of the first damping member 310, which can improve the deformation amount of the first damping member 310 when it is impacted, and is beneficial to improve the buffering effect of the first damping member 310 on the carrier 200.

[0066] When the first hollow cavity 311 is located in the first mounting hole 111, when the first damping member 310 deforms, the first mounting hole 111 limits the first damping member 310, avoiding the first damping member 310 from being twisted and deformed too much, thereby avoiding the first damping member 310 from being separated from the first metal member 510, and ensuring the installation stability of the first damping member 310.

[0067] The opening 315 of the first hollow cavity 311 is located on the side of the first damping member 310 away from the carrier 200, when the first damping member 310 contacts the carrier 200, the first damping member 310 can stably deform, avoiding the first damping member 310 from being deflected.

[0068] Of course, in other embodiments, the first hollow cavity 311 can be a closed cavity, that is, the first damping member 310 does not have an opening 315.

[0069] In some embodiments provided in the present application, as shown in FIG. 6, optionally, the first damping member 310 includes: a first damping part 312 and a second damping part 313, the first damping part 312 and the second damping part 313 are connected, the first damping part 312 and the second damping part 313 protrude towards the carrier 200 from the base 110, and the distance between the first damping part 312 and the carrier 200 is less than the distance between the second damping part 313 and the carrier 200.

[0070] In this embodiment, the first damping part 312 and the second damping part 313 protrude towards the carrier 200 from the base 110, so that the first damping part 312 and the second damping part 313 can play a buffering role on the carrier 200. D1 is the distance between the first damping part 312 and the carrier 200, and D2 is the distance between the second damping part 313 and the carrier 200. D1 is less than D2, that is, the distance between the first damping part 312 and the carrier 200 is less than the distance between the second damping part 313 and the carrier 200. When the carrier 200 moves towards the base 110 along the first direction Z, the first damping part 312 first flexibly abuts against the carrier 200 and elastically deforms, and when the carrier 200 continues to move, the second damping part 313 flexibly abuts against the carrier 200 again, thereby reducing the contact area between the first damping part 310 and the carrier 200 at the abutting moment, and reducing the adhesion between the first damping part 310 and the carrier 200, thereby avoiding the occurrence of adhesion between the first damping part 310 and the carrier 200.

[0071] In a possible application, the first damping part 312 is located at the center of the first damping part 310, and the second damping part 313 is arranged in the circumferential direction of the first damping part 312, or the number of the second damping parts 313 is multiple, and the multiple second damping parts 313 are uniformly distributed along the circumferential direction of the first damping part 312.

[0072] In another possible application, the second damping part 313 is located at the center of the first damping part 310, and the first damping part 312 is arranged in the circumferential direction of the second damping part 313, or the number of the first damping parts 312 is multiple, and the multiple first damping parts 312 are uniformly distributed along the circumferential direction of the second damping part 313.

[0073] Of course, in other embodiments, the side of the first damping part 310 facing the carrier 200 is a planar structure, or the side of the first damping part 310 facing the carrier 200 is provided with multiple groups of protruding structures, so as to reduce the contact area between the first damping part 310 and the carrier 200 and prevent the adhesion between the first damping part 310 and the carrier 200.

[0074] In a possible embodiment, the first damping part 310 further comprises a sixth damping part 314, the sixth damping part 314 and the second damping part 313 are connected, and the distance between the second damping part 313 and the carrier 200 is less than the distance between the sixth damping part 314 and the carrier 200. As shown in FIG. 6, D3 is the distance between the sixth damping part 314 and the carrier 200, and D2 is less than D3. In this way, the adhesion between the first damping part 310 and the carrier 200 is further reduced.

[0075] The buffering structure provided on the base 110 in this embodiment has good effects on large loads.

[0076] In some embodiments provided in the present application, as shown in FIG. 6, the base 110 is optionally provided with a limiting boss 520 protruding from the base 110 towards the carrier 200.

[0077] In this embodiment, when the carrier 200 moves towards the base 110, the first damping member 310 plays a buffering role for the carrier 200, however, when the moving amount of the carrier 200 is large, the first damping member 310 is excessively compressed, resulting in the carrier 200 being close to the base 110. In this embodiment, the limiting boss 520 is provided on the base 110, protruding from the base 110 towards the carrier 200, when the carrier 200 is close to the base 110, the carrier 200 abuts against the limiting boss 520 and stops moving, and the limiting boss 520 limits the position of the carrier 200. Avoiding the carrier 200 directly abutting against the base 110.

[0078] The base 110 is usually provided with electrical components and other components, and the limiting position of the carrier 200 is limited by the limiting boss 520, avoiding the carrier 200 colliding with the electrical components on the base 110, so as to protect the electrical components provided on the base 110.

[0079] Specifically, the distance between the limiting boss 520 and the carrier 200 is greater than the distance between the second damping part 313 and the carrier 200, so that the carrier 200 abuts against the second damping part 313 before abutting against the limiting boss 520, so as to ensure the buffering protection effect of the second damping part 313 on the carrier 200.

[0080] In some embodiments provided in the present application, as shown in FIG. 2, the second damping assembly 400 is optionally provided on the side of the carrier 200 facing the shell 120 along the first direction Z, the second damping assembly 400 is oppositely arranged with the second damping member 320, and the first damping member 310 is oppositely arranged with the carrier 200.

[0081] In this embodiment, in order to meet the thickness requirement of the driving motor 10, the second damping assembly 400 is only provided on the side of the carrier 200 facing the shell 100, of course, in other embodiments, the second damping assembly 400 can also be provided on the side of the carrier 200 facing the base 110.

[0082] The base 110 is usually an injection molding structure, and the shell 120 is usually a metal structure, therefore, the hardness of the shell 120 is usually greater than the hardness of the base 110, and in the same case, the impact sound of the carrier 200 impacting the shell 120 is greater than the impact sound of the carrier 200 impacting the base 110. When the driving motor 10 has a thickness limit, the second damping assembly 400 is provided on the side of the carrier 200 facing the shell 120, so as to ensure that a soft-to-soft buffering structure is formed between the carrier 200 and the shell 120, so as to reduce the impact sound when the carrier 200 and the shell 120 contact.

[0083] In some embodiments provided in the present application, as shown in FIG. 7, FIG. 8 and FIG. 9, the shell 120 is provided with a second mounting hole 121, the first part 321 of the second damping member 320 faces the shell 120, the shell 120 is used to support the first part 321, and the second part 322 of the second damping member 320 faces the second mounting hole 121, so that the second mounting hole 121 avoids the second part 322.

[0084] In this embodiment, the first part 321 of the second damping member 320 is arranged opposite to the shell 120, the shell 120 supports the first part 321, so that the second damping member 320 has a larger contact area with the shell 120, preventing the second damping member 320 from being separated from the shell 120. The second mounting hole 121 can avoid the second part 322 of the second damping member 320, and when the second part 322 deforms, the second part 322 is not blocked by the shell 120, improving the deformation amount of the second damping member 320, and further improving the buffering effect of the second damping member 320 on the carrier 200.

[0085] In some embodiments provided in the present application, as shown in FIG. 9, the first part 321 is connected with the second part 322, the first part 321 passes through the second mounting hole 121, the first part 321 is provided with a plug-in groove 323, the shell 120 is plugged into the plug-in groove 323, and the second part 322 is arranged opposite to the second mounting hole 121.

[0086] In this embodiment, the first part 321 is provided with the plug-in groove 323, the shell 120 is plugged into the plug-in groove 323, so that the second damping member 320 is installed on the shell 120, and the plug-in groove 323 and the shell 120 cooperate to limit the second damping member 320, improving the installation stability of the second damping member 320.

[0087] The second part 322 is arranged opposite to the second mounting hole 121, the second mounting hole 121 provides an avoiding space for the deformation of the second part 322, so that the shell 120 can avoid the deformation of the second damping member 320, improving the deformation amount of the second damping member 320, and further improving the buffering effect of the second damping member 320 on the carrier 200.

[0088] In other embodiments, a groove can be provided on the shell 120, and the second part 322 of the second damping member 320 is arranged opposite to the groove, so as to form an avoiding space between the second part 322 and the groove.

[0089] In a possible application, the second damping member 320 is fixed on the shell 120 by injection molding.

[0090] In other embodiments, the insertion slot 323 can be arranged on the housing 120, and a portion of the second damping member 320 is injection molded into the housing 120.

[0091] In some embodiments provided in the present application, as shown in FIG. 10, the side of the housing 120 facing away from the carrier 200 is provided with a receiving slot 122, which is used to accommodate the first part 321, so that the side of the housing 120 facing away from the carrier 200 is flush with the first part 321.

[0092] Since the housing 120 needs to be inserted into the insertion slot 323, the side of the housing 120 facing the carrier 200 and the side of the housing 120 facing away from the carrier 200 are both covered with the second damping member 320.

[0093] The receiving slot 122 is arranged on the side of the housing 120 facing away from the carrier 200, and the first part 321 on the outer side of the housing 120 can be accommodated in the receiving slot 122, so that the first part 321 does not protrude from the outer surface of the housing 120, ensuring that the second damping member 320 and the outer surface of the housing 120 are flush. The second damping member 320 does not protrude from the outer surface of the housing 120, thereby avoiding interference between the second damping member 320 and other components outside the drive motor 10, and avoiding the second damping member 320 from being detached from the housing 120 due to external interference.

[0094] In some embodiments, as shown in FIG. 11, the drive motor 10 further comprises a second metal member 530 arranged on the housing 120, the housing 120 is provided with a second mounting hole 121, a portion of the second damping member 320 is arranged on the second metal member 530, and another portion of the second damping member 320 is arranged opposite to the second mounting hole 121.

[0095] The second damping member 320 is usually installed by injection molding process, however, in the case of limited installation space on the housing 120, it is difficult to injection mold the second damping member 320 on the base 110.

[0096] Therefore, when installing the second damping member 320, the second damping member 320 is pre-assembled on the second metal member 530, that is, before the second damping member 320 is assembled into the housing 120, the second damping member 320 is injection molded on the second metal member 530 externally, and at this time, the injection molding process of the second damping member 320 is not limited by the space in the housing 120.

[0097] The second damping member 320 and the second metal member 530 form an assembly, and the assembly is mounted on the shell 120. The second metal member 530 can be fixed on the shell 120 by welding or bonding. The second metal member 530 is simple to install, thereby improving the convenience of installing the second damping member 320 on the shell 120.

[0098] The shell 120 is provided with a second mounting hole 121. The second mounting hole 121 provides a space for the second damping member 320 to deform, improves the deformation amount of the second damping member 320, and improves the buffering effect of the second damping member 320 on the carrier 200.

[0099] Of course, in other embodiments, the second damping member 320 can be directly injection molded on the shell 120.

[0100] As shown in FIG. 12, in some embodiments, the second damping member 320 includes a Mylar damping member and / or a foam damping member.

[0101] The second damping member 320 can be made of Mylar, or the second damping member 320 can be made of foam, or the second damping member 320 can include both Mylar and foam. The second damping member 320 can be directly attached to the inner side of the shell 120, so that the second damping member 320 serves as an impact buffering component of the carrier 200. The second damping member 320 in the embodiment has the advantages of saving space, simple process, and low cost.

[0102] As shown in FIG. 9, in some embodiments, the second damping assembly 400 includes a third damping portion 410 and a fourth damping portion 420. Along the first direction Z, the third damping portion 410 is arranged on the side of the carrier 200 facing the shell 100, and the fourth damping portion 420 is arranged on the side of the third damping portion 410 facing the first damping assembly 300. The fourth damping portion 420 and the third damping portion 410 are arranged in a stepped manner.

[0103] The third damping portion 410 and the fourth damping portion 420 can buffer the carrier 200. The fourth damping portion 420 and the third damping portion 410 are arranged in a stepped manner, so that the fourth damping portion 420 can protrude from the surface of the third damping portion 410.

[0104] D4 is the distance between the third damping part 410 and the first damping assembly 300, and D5 is the distance between the fourth damping part 420 and the carrier 200, and D5 is smaller than D4. When the carrier 200 moves towards the shell 120 along the first direction Z, the fourth damping part 420 first flexibly abuts against the first damping assembly 300 and elastically deforms, and when the carrier 200 continues to move, the third damping part 410 flexibly abuts against the second damping part 320, thereby reducing the contact area between the second damping assembly 400 and the first damping assembly 300 at the abutting moment, reducing the adhesion between the second damping assembly 400 and the first damping assembly 300, and avoiding the adhesion phenomenon between the second damping assembly 400 and the first damping assembly 300.

[0105] The fourth damping part 420 is arranged opposite to the first damping assembly 300, so as to form a soft-to-soft buffer between the fourth damping part 420 and the first damping assembly 300. When the moving amount of the carrier 200 is large, the buffer effect of the fourth damping part 420 is limited, and in order to avoid the carrier 200 directly rigidly contacting the shell 100, the third damping part 410 is arranged opposite to the shell 100, so as to further protect the carrier 200 and the shell 100 through the third damping part 410.

[0106] The stepped structure can also ensure the structural stability and damping function stability of the second damping assembly 400.

[0107] As shown in FIG. 9, in some embodiments, optionally, the second damping assembly 400 further comprises a fifth damping part 430, the fifth damping part 430 is arranged on the fourth damping part 420, the fifth damping part 430 is arranged opposite to the first damping assembly 300, and the fifth damping part 430 and the fourth damping part 420 are arranged in a stepped manner.

[0108] The fifth damping part 430 is arranged on the fourth damping part 420, so that a multi-stage stepped structure is formed on the second damping assembly 400, and the adhesion phenomenon between the second damping assembly 400 and the second damping part 320 is further weakened.

[0109] Of course, in other embodiments, more stages of stepped structures can also be arranged, which will not be described here.

[0110] In the embodiment, the fifth damping part 430 is arranged opposite to the second part 322 in the second damping part 320, the fifth damping part 430 and the second part 322 perform a first-stage soft-to-soft buffer, and since the shell 120 avoids the second part 322, the fifth damping part 430 and the second part 322 have a good buffer effect. The fourth damping part 420 is arranged opposite to the first part 321 in the second damping part 320, and the fourth damping part 420 and the first part 321 form a second-stage soft-to-soft buffer. The third damping part 410 is arranged opposite to the shell 120, thereby forming a third-stage buffer.

[0111] In combination with FIGS. 2 and 13, in some embodiments, the side portion of the carrier 200 is optionally provided with a second shock absorption assembly 400, so that a part of the second shock absorption assembly 400 is located between the side portion of the carrier 200 and the side portion of the shell 100.

[0112] A part of the second shock absorption assembly 400 extends to the side portion of the carrier 200, avoiding the direct contact between the side portion of the carrier 200 and the side portion of the shell 100.

[0113] Although the carrier 200 does not have the need to move directly along the vertical direction Z, when the electronic device is impacted or falls, the carrier 200 may have a certain amount of offset relative to the shell 100, and the carrier 200 may hit the shell 100 at this time. Therefore, a part of the second shock absorption assembly 400 is arranged between the side portion of the carrier 200 and the side portion of the shell 100, avoiding the direct impact between the side portion of the carrier 200 and the side portion of the shell 100, preventing the rigid contact between the carrier 200 and the shell 100, and reducing the damage rate of the carrier 200 and the shell 100.

[0114] In combination with FIGS. 16 and 17, in some embodiments, the first end face 440 of the second shock absorption assembly 400 faces the side portion of the shell 100, and the circumferential edge of the first end face 440 is provided with a rounded corner 450.

[0115] The end face of the second shock absorption assembly 400 facing the side portion of the shell 100 is set as the first end face 440, and the circumferential edge of the first end face 440 is processed to form a rounded corner 450. When the carrier 200 moves towards the side portion of the shell 100, the first end face 440 contacts the side portion of the shell 100, and the rounded corner 450 can reduce the contact area between the first end face 440 and the shell 100, thereby reducing the adhesion between the first end face 440 and the shell 100, and avoiding the occurrence of the adhesion phenomenon between the first end face 440 and the shell 100.

[0116] In other embodiments, a recess structure can be processed on the first end face 440, which can reduce the contact area between the first end face 440 and the shell 100, thereby reducing the adhesion between the first end face 440 and the shell 100.

[0117] In other embodiments, the first end face 440 is a spherical surface, which is used to reduce the contact area between the first end face 440 and the shell 100.

[0118] In combination with FIGS. 13, 14, 16 and 18, in some embodiments, the two sides of the carrier 200 are optionally provided with the second damping assembly 400 along the second direction X, and one side of the carrier 200 is provided with the second damping assembly 400 along the third direction Y, both the second direction X and the third direction Y being perpendicular to the first direction Z. The driving motor 10 further comprises: a plurality of balls 600 located between the other side of the carrier 200 and the shell 100 along the third direction Y, the carrier 200 moving relative to the carrier 200 along the first direction Z through the balls 600.

[0119] The carrier 200 is capable of moving relative to the shell 100 along the first direction Z, and the balls 600 are arranged between the carrier 200 and the shell 100, which can be used to reduce the frictional force when the carrier 200 moves, and ensure the smoothness and smoothness of the movement of the carrier 200 relative to the shell 100.

[0120] Along the second direction X, the two sides of the carrier 200 are provided with the second damping assembly 400, so that when the carrier 200 shakes along the second direction X, the two sides of the carrier 200 can be buffered by the second damping assembly 400. Along the third direction Y, one side of the carrier 200 is provided with the second damping assembly 400, and the other side of the carrier 200 is distributed with the balls 600. In order to ensure that the carrier 200 can stably slide along the balls 600, the other side of the carrier 200 cannot be provided with the second damping assembly 400, so as to prevent the balls 600 from contacting the soft structure of the second damping assembly 400.

[0121] In combination with FIGS. 14, 15, 16 and 17, the second damping assembly 400 comprises a third damping member 480 and a fourth damping member 490, the third damping member 480 protruding the carrier 200 along two adjacent directions, and the fourth damping member 490 protruding the carrier 200 along a single direction.

[0122] In combination with FIGS. 16, 17 and 19, in some embodiments, a part of the second damping assembly 400 extends out of the side of the carrier 200, and a second hollow cavity 460 is arranged on the part of the second damping assembly 400 extending out of the side of the carrier 200.

[0123] When the carrier 200 moves towards the side of the shell 100, the second hollow cavity 460 provides space for the deformation of the second damping assembly 400 when the second damping assembly 400 deforms, which can improve the deformation amount of the second damping assembly 400 and is beneficial to improve the buffering effect of the second damping assembly 400 on the carrier 200.

[0124] Exemplarily, the second hollow cavity 460 can be a closed cavity or a side-open cavity.

[0125] In combination with FIGS. 20 and 21, in some embodiments, the carrier 200 optionally comprises a support 210, a bearing 220 connected to the support 210, and a movable part 230, the second shock-absorbing assembly 400 being arranged on the bearing 220. The movable part 230 is located between the support 210 and the bearing 220 and is movable relative to the support 210 along the second direction X and the third direction Y, and the movable part 230 is configured to carry the lens, and a portion of the second shock-absorbing assembly 400 protrudes out of the bearing 220 towards the movable part 230.

[0126] The support 210 and the bearing 220 define a movement space therebetween, in which the movable part 230 is movable along the second direction X and the third direction Y, and the lens is mounted on the movable part 230, so that the movable part 230 drives the lens to move along the second direction X and the third direction Y, thereby achieving the anti-shake function of the lens.

[0127] The second shock-absorbing assembly 400 protrudes out of the bearing 220 towards the movable part 230, and when the movable part 230 moves relative to the bearing 220, the movable part 230 can abut against the second shock-absorbing assembly 400, which buffers the movable part 230 and reduces the impact sound when the movable part 230 moves, and also reduces the damage rate of the movable part 230.

[0128] In combination with FIGS. 20, 21 and 22, in some embodiments, the second shock-absorbing assembly 400 is provided with a third hollow cavity 470, which protrudes out of the inner wall of the bearing 220 towards the movable part 230.

[0129] The movable part 230 moves in the support 210 and the bearing 220, so that when the second shock-absorbing assembly 400 deforms, the third hollow cavity 470 provides space for the deformation of the second shock-absorbing assembly 400, which can increase the deformation amount of the second shock-absorbing assembly 400 and is conducive to improving the buffering effect of the second shock-absorbing assembly 400 on the movable part 230.

[0130] For example, the third hollow cavity 470 can be a closed cavity or a cavity with an open side.

[0131] In the above embodiments, the first shock-absorbing assembly 300 and the second shock-absorbing assembly 400 can be flexibly adjusted by replacing elastic body materials with different hardnesses to achieve a balance between performance and buffering effect.

[0132] In the above embodiments, the features of the buffering and shock-absorbing structure include contact features, buffering and shock-absorbing features, and second-order or multi-order impact protection features.

[0133] The contact features are used to increase the buffering space and also ensure the stability of the performance and avoid the start-up delay caused by sticking.

[0134] The buffer shock-absorbing feature increases the buffer and reduces the impact sound by using low-hardness elastic material contact, plus the elastic deformation shock-absorbing of the elastic drum surface / hollow cylinder.

[0135] The second-order or multi-order convex platform is used as a limit protection to ensure the structure and function are intact.

[0136] The whole impact shock-absorbing process includes point contact, surface contact, elastic body deformation shock-absorbing, and second-order / multi-order stop surface protection.

[0137] The embodiment improves the structure of the driving motor 10, sets a buffer shock-absorbing structure at the internal impact position, absorbs and disperses the impact energy, reduces the impact force when impacting, can effectively reduce the impact noise generated during the working process of the driving motor 10, improves the quietness of the camera, and can improve the user experience. At the same time, it is also beneficial to protect the integrity of the internal movement structure and improve the reliability of the impact resistance.

[0138] As shown in FIG. 23, in the embodiment of the present application, a camera module is provided, which includes a lens 700 and the driving motor 10 in any of the above embodiments. The lens 700 is arranged on the driving motor 10, and the camera module can achieve the same technical effects as in any of the above embodiments, which will not be described here.

[0139] In a possible application, the lens 700 is arranged on the carrier 200.

The power supply 800 is electrically connected to the driving motor 10, and the lens 700 is arranged on the driving motor 10. The electronic device can achieve the same technical effects as in any of the above embodiments, which will not be described here.

[0141] The electronic device includes any one of the following: a mobile phone, a tablet computer, a smart wearable device, and an electronic book.

[0142] In the description of the present specification, the description of the terms "one embodiment", "some embodiments", "exemplary embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application.
