Description

Technical Field

[0001] The present application belongs to the technical field of camera modules, and specifically relates to a driving motor, a camera module and an electronic device. Background Art

[0002] The miniature camera motors used in portable electronic devices such as smartphones and tablets have movable gaps in the lens or chip due to focusing and anti-shake requirements. When the electronic device is shaken or subjected to other external forces, it is easy to produce abnormal impact noises, affecting the user experience.

[0003] Usually, a buffer component can be set on the carrier to provide buffering between the carrier and the shell. However, the buffer component in the prior art has limited buffering effect on the carrier. When the carrier is heavy or subjected to a large external force, the camera motor will still make obvious abnormal noises. Therefore, how to further improve the buffering effect on the carrier has become an urgent problem to be solved. Summary of the Invention

[0004] The present application aims to provide a driving motor, a camera module and an electronic device, which at least solve the problem in the related art that when the electronic device encounters shaking or other external forces, it is easy to produce abnormal impact noise.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] In a first aspect, the present application proposes a drive motor, comprising:

[0007] case;

[0008] A carrier is located in the housing and is used to carry the lens. The carrier is capable of moving relative to the housing along a first direction.

[0009] At least one first shock absorbing assembly is provided on the housing, wherein the first shock absorbing assembly is provided on two opposite sides of the housing along a first direction, and the first shock absorbing assembly protrudes from the housing toward the interior of the housing;

[0010] At least one second shock-absorbing component is arranged on the carrier. Along the first direction, a second shock-absorbing component is arranged on one side of the carrier and / or the other side of the carrier. The second shock-absorbing component protrudes from the outer surface of the carrier and faces the first shock-absorbing component.

[0011] In a second aspect, the present application proposes a camera module, comprising:

[0012] lens;

[0013] As in the driving motor of the first aspect, the lens is arranged on the driving motor.

[0014] In a third aspect, the present application proposes an electronic device, comprising:

[0015] power supply;

[0016] lens;

[0017] As in the driving motor of the first aspect, the power supply is electrically connected to the driving motor, and the lens is disposed on the driving motor.

[0018] In an embodiment of the present application, when the carrier moves along the first direction in the shell, the second shock-absorbing assembly can flexibly abut against the first shock-absorbing assembly, jointly preventing direct collision between the carrier and the shell, so as to enhance the buffering protection effect between the carrier and the shell along the first direction, and enhance the effect of reducing abnormal collision noise, thereby extending the service life of the drive motor.

[0019] Shock-absorbing structures are provided on both the shell and the carrier. When the carrier moves in the shell, a soft-to-soft collision is formed between the shell and the carrier, thereby achieving maximum shock-absorbing and buffering effect. Even if the carrier is heavy or the driving motor is subjected to a large external force, the first shock-absorbing assembly and the second shock-absorbing assembly can effectively play a buffering effect to prevent the driving motor from making abnormal noises.

[0050] Refer to the following Figures 1 to 23 Describe the driving motor, camera module and electronic device according to some embodiments of the present application.

[0051] The embodiment of the present application provides a driving motor, combined with Figure 1 and Figure 2 As shown, the drive motor 10 includes a housing 100, a carrier 200, a first shock-absorbing assembly 300, and a second shock-absorbing assembly 400. The carrier 200 is located within the housing 100 and is used to support the lens. The carrier 200 is movable relative to the housing 100 along a first direction Z. There is at least one first shock-absorbing assembly 300 and at least one second shock-absorbing assembly 400. The first shock-absorbing assembly 300 is disposed on the housing 100, with the first shock-absorbing assembly 300 disposed on opposite sides of the housing 100 along the first direction Z. The first shock-absorbing assembly 300 protrudes from the interior of the housing 100. The second shock-absorbing assembly 400 is disposed on the carrier 200, with the second shock-absorbing assembly 400 disposed on one side and / or the other side of the carrier 200 along the first direction Z. The second shock-absorbing assembly 400 protrudes from the outer surface of the carrier 200 and faces the first shock-absorbing assembly 300.

[0052] In this embodiment, the lens is mounted on a carrier 200, which is typically magnetically encased and suspended. The carrier 200 is located within the housing 100, and a drive assembly is capable of driving the carrier 200 to move relative to the housing 100, thereby adjusting the position of the lens.

[0053] The carrier 200 can move relative to the housing 100 along the first direction Z. Figure 2 As shown, 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.

[0054] Along the first direction Z, first shock absorbing assemblies 300 are provided on two opposite sides of the shell 100, and the first shock absorbing assemblies 300 protrude from the shell 100 toward the inside of the shell 100, that is, first shock absorbing assemblies 300 are provided on the upper and lower sides of the inner wall of the shell 100, and the first shock absorbing assemblies 300 are located between the carrier 200 and the shell 100. The first shock absorbing assembly 300 can buffer the carrier 200, avoid direct contact between the carrier 200 and the shell 100, thereby preventing direct collision between the carrier 200 and the shell 100, and reducing abnormal noise generated during collision.

[0055] Along the first direction Z, a second shock absorbing assembly 400 is provided on one side and / or the other side of the carrier 200. The second shock absorbing assembly 400 protrudes from the outer surface of the carrier 200 and is located between the carrier 200 and the housing 100. The second shock absorbing assembly 400 is disposed opposite the first shock absorbing assembly 300, that is, the second shock absorbing assembly 400 faces the first shock absorbing assembly 300. When the carrier 200 moves within the housing 100 along the first direction Z, the second shock absorbing assembly 400 can flexibly abut against the first shock absorbing assembly 300, thereby jointly preventing direct collision between the carrier 200 and the housing 100. This enhances the buffering protection between the carrier 200 and the housing 100 along the first direction Z, improves the effect of reducing abnormal collision noise, and extends the service life of the drive motor 10.

[0056] In this embodiment, shock-absorbing structures are provided on both the shell 100 and the carrier 200. 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 achieving a maximized shock-absorbing and buffering effect. Even if the carrier 200 is heavy or the drive motor 10 is subjected to a large external force, the first shock-absorbing assembly 300 and the second shock-absorbing assembly 400 can effectively play a buffering effect to prevent the drive motor 10 from making abnormal noises.

[0057] The soft-on-soft impact buffering structure in this embodiment provides a larger buffering and shock-absorbing space, and the overall effect can reduce noise by 10dB to 20dB.

[0058] Exemplarily, the number of the first shock absorbing assembly 300 and the second shock absorbing assembly 400 can be multiple, the first shock absorbing assembly 300 is distributed along the circumference of the shell 100, and the second shock absorbing assembly 400 is distributed along the circumference of the carrier 200. The first shock absorbing assembly 300 and the second shock absorbing assembly 400 are evenly distributed and the number is the same. For example, the number of the first shock absorbing assembly 300 and the second shock absorbing assembly 400 are both 4. Of course, in other embodiments, the number of the first shock absorbing assembly 300 and the second shock absorbing assembly 400 is not limited to 4.

[0059] In some embodiments provided in this application, Figure 1 and Figure 2As shown, optionally, the first shock absorbing assembly 300 includes a first shock absorbing member 310 and a second shock absorbing member 320. The housing 100 includes a base 110 and an outer shell 120. The first shock absorbing member 310 is disposed on a side of the base 110 facing the carrier 200, and the carrier 200 is movable relative to the base 110 along a first direction Z. The outer shell 120 is sleeved on the base 110, with the carrier 200 located between the base 110 and the outer shell 120. The second shock absorbing member 320 is disposed on a side of the outer shell 120 facing the carrier 200.

[0060] In this embodiment, the housing 120 is disposed on the base 110. For example, the housing 120 can be bonded or fixed to the base 110 via a connector. A receiving space is formed between the housing 120 and the base 110. The carrier 200 is located in the receiving space and can move along the first direction Z within the receiving space.

[0061] The first shock absorber 310 is disposed on the base 110 and is located between the carrier 200 and the base 110 . When the carrier 200 moves toward the base 110 , the first shock absorber 310 cushions the carrier 200 and prevents the carrier 200 from directly hitting the base 110 .

[0062] The second shock absorber 320 is provided on the housing 100 and is located between the carrier 200 and the housing 100 . When the carrier 200 moves toward the housing 100 , the second shock absorber 320 has a buffering effect on the carrier 200 to prevent the carrier 200 from directly hitting the housing 100 .

[0063] Along the first direction Z, the second shock absorbing assembly 400 is disposed on one or both sides of the carrier 200. For example, the second shock absorbing assembly 400 is disposed on the side of the carrier 200 facing the carrier 200, or the second shock absorbing assembly 400 is disposed on the side of the carrier 200 facing the housing 100. Alternatively, the second shock absorbing assembly 400 is disposed on both the side of the carrier 200 facing the carrier 200 and the side facing the housing 100.

[0064] When the first shock absorber 310 faces the second shock absorber 400, a soft-to-soft buffer structure is formed between the carrier 200 and the base 110. When the second shock absorber 320 faces the second shock absorber 400, a soft-to-soft buffer structure is formed between the carrier 200 and the housing 100.

[0065] The first shock absorber 310 and the second shock absorber 320 are made of elastic materials capable of buffering impact. For example, the first shock absorber 310 and the second shock absorber 320 can be made of TPU (Thermoplastic polyurethanes), TPE (Thermoplastic rubber) or silicone material.

[0066] In some embodiments provided in the present application, in combination with Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 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, the first metal piece 510 is 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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 avoiding 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.

[0071] The first metal piece 510 can be mounted in the first mounting hole 111, or the first metal piece 510 is mounted 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.

[0072] Of course, in other embodiments, the first damping piece 310 can be directly injection molded on the base 110.

[0073] In some embodiments provided in the present application, as shown in Figure 6 Optionally, the first damping piece 310 is provided with a first hollow cavity 311, and the first hollow cavity 311 has an opening 315, and the opening 315 is located on a side of the first damping piece 310 away from the carrier 200, and the first hollow cavity 311 is located in the first mounting hole 111.

[0074] In this embodiment, when the first damping piece 310 deforms, the first hollow cavity 311 provides space for the deformation of the first damping piece 310, which can improve the deformation amount of the first damping piece 310 when it is impacted, and is beneficial to improve the buffering effect of the first damping piece 310 on the carrier 200.

[0075] When the first damping piece 310 deforms, the first mounting hole 111 limits the first damping piece 310, avoiding large torsional deformation of the first damping piece 310, thereby avoiding the first damping piece 310 from being separated from the first metal piece 510, and ensuring the installation stability of the first damping piece 310.

[0076] The opening 315 of the first hollow cavity 311 is located on a side of the first damping piece 310 away from the carrier 200, and when the first damping piece 310 contacts the carrier 200, the first damping piece 310 can stably deform, avoiding deflection of the first damping piece 310.

[0077] Of course, in other embodiments, the first hollow cavity 311 can be a closed cavity, that is, the first damping piece 310 does not have an opening 315.

[0078] In some embodiments provided in the present application, as shown in Figure 6 Optionally, the first damping piece 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 from the base 110 towards the carrier 200, 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.

[0079] In this embodiment, the first shock absorbing portion 312 and the second shock absorbing portion 313 protrude from the base 110 toward the carrier 200, so that the first shock absorbing portion 312 and the second shock absorbing portion 313 can provide a buffering effect on the carrier 200. D1 is the distance between the first shock absorbing portion 312 and the carrier 200, and D2 is the distance between the second shock absorbing portion 313 and the carrier 200. D1 is smaller than D2, that is, the distance between the first shock absorbing portion 312 and the carrier 200 is smaller than the distance between the second shock absorbing portion 313 and the carrier 200. When the carrier 200 approaches the base 110 along the first direction Z, the first shock absorbing portion 312 first flexibly abuts against the carrier 200 and generates elastic deformation. When the carrier 200 continues to move, the second shock absorbing portion 313 flexibly abuts against the carrier 200 again, reducing the contact area between the first shock absorbing member 310 and the carrier 200 at the moment of abutment, thereby reducing the adhesion force between the first shock absorbing member 310 and the carrier 200, and avoiding the occurrence of sticking between the first shock absorbing member 310 and the carrier 200.

[0080] In one possible application, the first shock absorbing portion 312 is located at the center of the first shock absorbing member 310, and the second shock absorbing portion 313 is arranged around the circumference of the first shock absorbing portion 312, or there are multiple second shock absorbing portions 313, and the multiple second shock absorbing portions 313 are evenly distributed along the circumference of the first shock absorbing portion 312.

[0081] In another possible application, the second shock absorber 313 is located at the center of the first shock absorber 310, and the first shock absorber 312 is arranged around the circumference of the second shock absorber 313, or there are multiple first shock absorbers 312, and the multiple first shock absorbers 312 are evenly distributed along the circumference of the second shock absorber 313.

[0082] Of course, in other embodiments, the side of the first shock absorber 310 facing the carrier 200 is a planar structure, or the side of the first shock absorber 310 facing the carrier 200 is provided with multiple groups of protrusion structures to reduce the contact area between the first shock absorber 310 and the carrier 200 and prevent the first shock absorber 310 from adhering to the carrier 200.

[0083] In a possible embodiment, the first shock absorbing member 310 further includes a sixth shock absorbing portion 314, the sixth shock absorbing portion 314 is connected to the second shock absorbing portion 313, and the distance between the second shock absorbing portion 313 and the carrier 200 is smaller than the distance between the sixth shock absorbing portion 314 and the carrier 200. Figure 6 As shown, D3 is the distance between the sixth shock absorbing portion 314 and the carrier 200 , and D2 is smaller than D3 . Through the above-mentioned method, the adhesion force between the first shock absorbing member 310 and the carrier 200 is further reduced.

[0084] The buffer structure provided on the base 110 in this embodiment has a better effect in the case of heavy loads.

[0085] In some embodiments provided in this application, Figure 6 As shown, optionally, a limiting boss 520 is provided on the base 110 , and the limiting boss 520 protrudes from the base 110 toward the carrier 200 .

[0086] In this embodiment, when the carrier 200 moves toward the base 110, the first shock absorber 310 acts as a buffer for the carrier 200. However, when the carrier 200 moves significantly, the first shock absorber 310 is excessively squeezed, causing the carrier 200 to come close to the base 110. In this embodiment, a limiting protrusion is provided on the base 110. The limiting boss 520 protrudes from the base 110 toward the carrier 200. When the carrier 200 comes close to the base 110, the carrier 200 abuts the limiting boss 520 and stops moving. The limiting boss 520 limits the position of the carrier 200, preventing the carrier 200 from directly contacting the base 110.

[0087] The base 110 is usually provided with components such as electrical components. The limiting boss 520 limits the extreme position of the carrier 200 to prevent the carrier 200 from colliding with the electrical components on the base 110, thereby protecting the electrical components provided on the base 110.

[0088] Specifically, the distance between the limiting boss 520 and the carrier 200 is greater than the distance between the second shock absorbing part 313 and the carrier 200, so that the carrier 200 can only abut against the limiting boss 520 after abutting against the second shock absorbing part 313, thereby ensuring the buffering protection effect between the second shock absorbing part 313 and the carrier 200.

[0089] In some embodiments provided in this application, Figure 2 As shown, optionally, along the first direction Z, a second shock absorbing assembly 400 is provided on the side of the carrier 200 facing the housing 120 . The second shock absorbing assembly 400 is arranged opposite to the second shock absorbing member 320 , and the first shock absorbing member 310 is arranged opposite to the carrier 200 .

[0090] In this embodiment, in order to meet the thickness requirement of the driving motor 10, a second shock-absorbing assembly 400 is only provided on the side of the carrier 200 facing the shell 100. Of course, in other embodiments, a second shock-absorbing assembly 400 may also be provided on the side of the carrier 200 facing the base 110.

[0091] The base 110 is typically an injection-molded structure, and the housing 120 is typically a metal structure. Therefore, the hardness of the housing 120 is typically greater than that of the base 110. Under the same conditions, the impact sound produced by the carrier 200 striking the housing 120 is louder than the impact sound produced by the carrier 200 striking the base 110. If the drive motor 10 is limited in thickness, a second shock-absorbing assembly 400 is provided on the side of the carrier 200 facing the housing 120 to ensure a soft-to-soft buffer structure is formed between the carrier 200 and the housing 120, thereby reducing the impact sound produced when the carrier 200 and the housing 120 make contact.

[0092] In some embodiments provided in this application, Figure 7 、 Figure 8 and Figure 9 As shown, optionally, a second mounting hole 121 is provided on the shell 120, the first part 321 of the second shock absorber 320 faces the shell 120, the shell 120 is used to support the first part 321, and the second part 322 of the second shock absorber 320 faces the second mounting hole 121, so that the second mounting hole 121 avoids the second part 322.

[0093] In this embodiment, the first portion 321 of the second shock absorber 320 is disposed opposite the housing 120. The housing 120 supports the first portion 321, thereby ensuring a larger contact area between the second shock absorber 320 and the housing 120 and preventing the second shock absorber 320 from separating from the housing 120. The second mounting hole 121 allows for the second portion 322 of the second shock absorber 320 to be avoided. When the second portion 322 deforms, it is not blocked by the housing 120. This increases the deformation capacity of the second shock absorber 320 and, in turn, enhances the cushioning effect of the second shock absorber 320 on the carrier 200.

[0094] In some embodiments provided in this application, Figure 9 As shown, optionally, the first part 321 is connected to the second part 322, the first part 321 passes through the second mounting hole 121, and the first part 321 is provided with a plug-in slot 323, the shell 120 is plugged into the plug-in slot 323, and the second part 322 is arranged opposite to the second mounting hole 121.

[0095] In this embodiment, a plug-in slot 323 is provided on the first part 321, and the shell 120 is plugged into the plug-in slot 323, so that the second shock absorber 320 is installed on the shell 120. The plug-in slot 323 and the shell 120 cooperate in such a way that the shell 120 limits the second shock absorber 320, thereby improving the installation stability of the second shock absorber 320.

[0096] The second part 322 is arranged opposite to the second mounting hole 121, and the second mounting hole 121 provides an avoidance space for the deformation of the second part 322, so that the shell 120 can avoid the deformation of the second shock absorber 320, thereby increasing the deformation that the second shock absorber 320 can produce, and thereby improving the buffering effect of the second shock absorber 320 on the carrier 200.

[0097] In other embodiments, a groove may be provided on the housing 120 , and the second portion 322 of the second shock-absorbing member 320 is disposed opposite to the groove, thereby forming an escape space between the second portion 322 and the groove.

[0098] In a possible application, the second shock-absorbing member 320 is fixed to the housing 120 by injection molding.

[0099] In other embodiments, the inserting slot 323 may be provided on the housing 120 , and a portion of the second shock absorbing member 320 may be injection molded into the housing 120 .

[0100] In some embodiments provided in this application, Figure 10 As shown, optionally, a receiving groove 122 is provided on the side of the housing 120 facing away from the carrier 200 , and the receiving groove 122 is used to receive the first portion 321 so that the side of the housing 120 facing away from the carrier 200 is flush with the first portion 321 .

[0101] 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 shock-absorbing member 320 .

[0102] A receiving groove 122 is provided on the side of the housing 120 facing away from the carrier 200. The first portion 321, located on the outward side of the housing 120, can be received in the receiving groove 122, so that the first portion 321 does not protrude from the outer surface of the housing 120, ensuring that the second shock absorber 320 is flush with the outer surface of the housing 120. The second shock absorber 320 does not protrude from the outer surface of the housing 120, thereby preventing the second shock absorber 320 from interfering with other components outside the drive motor 10 and preventing the second shock absorber 320 from being separated from the housing 120 due to external interference.

[0103] In some embodiments, optionally, as Figure 11 As shown, the drive motor 10 also includes: a second metal part 530, the second metal part 530 is arranged on the outer shell 120, the outer shell 120 is provided with a second mounting hole 121, a part of the second shock absorber 320 is arranged on the second metal part 530, and the other part of the second shock absorber 320 is arranged opposite to the second mounting hole 121.

[0104] The second shock absorbing member 320 is usually installed by using an injection molding process. However, when the installation space on the housing 120 is limited, it is difficult to injection-mold the second shock absorbing member 320 on the base 110 .

[0105] Therefore, when installing the second shock absorber 320, the second shock absorber 320 is pre-installed on the second metal part 530, that is, before the second shock absorber 320 is installed into the outer shell 120, the second shock absorber 320 is first injection molded on the second metal part 530 on the outside. At this time, the injection molding process of the second shock absorber 320 is not limited by the space inside the outer shell 120.

[0106] The second shock absorber 320 and the second metal member 530 form an assembly, which is then installed together on the housing 120. The second metal member 530 can be fixed to the housing 120 by welding or bonding. The installation method of the second metal member 530 is simple, thereby improving the convenience of installing the second shock absorber 320 on the housing 120.

[0107] The housing 120 is provided with a second mounting hole 121 , which provides an escape space for the second shock absorber 320 when it is deformed, thereby increasing the deformation amount that the second shock absorber 320 can produce, thereby improving the buffering effect of the second shock absorber 320 on the carrier 200 .

[0108] Of course, in other embodiments, the second shock-absorbing component 320 may also be directly injection-molded onto the housing 120 .

[0109] like Figure 12 As shown, in some embodiments, optionally, the second shock absorber 320 includes: a Mylar shock absorber and / or a foam shock absorber.

[0110] The second shock absorber 320 can be made of Mylar, or foam, or can include both Mylar and foam. The second shock absorber 320 can be directly attached to the inner side of the housing 120, thereby acting as a shock absorber for impact with the carrier 200. The second shock absorber 320 in this embodiment has the advantages of space saving, simple manufacturing, and low cost.

[0111] like Figure 9 As shown, in some embodiments, optionally, the second shock absorbing assembly 400 includes: a third shock absorbing portion 410 and a fourth shock absorbing portion 420. Along the first direction Z, the third shock absorbing portion 410 is arranged on the side of the carrier 200 facing the shell 100, and the fourth shock absorbing portion 420 is arranged on the side of the third shock absorbing portion 410 facing the first shock absorbing assembly 300. The fourth shock absorbing portion 420 and the third shock absorbing portion 410 are distributed in a stepped manner.

[0112] The third shock absorbing portion 410 and the fourth shock absorbing portion 420 can buffer the carrier 200. The fourth shock absorbing portion 420 and the third shock absorbing portion 410 are distributed in a stepped manner, so that the fourth shock absorbing portion 420 can protrude from the surface of the third shock absorbing portion 410.

[0113] D4 is the distance between the third damping portion 410 and the first damping assembly 300, and D5 is the distance between the fourth damping portion 420 and the carrier 200, with D5 being smaller than D4. When the carrier 200 approaches the housing 120 along the first direction Z, the fourth damping portion 420 first flexibly abuts against the first damping assembly 300 and undergoes elastic deformation. As the carrier 200 continues to move, the third damping portion 410 then flexibly abuts against the second damping portion 320, reducing the contact area between the second damping assembly 400 and the first damping assembly 300 at the moment of abutment. This reduces the adhesion between the second damping assembly 400 and the first damping assembly 300, thereby preventing sticking between the second damping assembly 400 and the first damping assembly 300.

[0114] The fourth shock absorbing portion 420 and the first shock absorbing assembly 300 are arranged opposite each other, thereby forming a soft-on-soft buffer between the fourth shock absorbing portion 420 and the first shock absorbing assembly 300. When the carrier 200 moves a large amount, the buffering effect of the fourth shock absorbing portion 420 is limited. To prevent the carrier 200 from directly and rigidly contacting the housing 100, the third shock absorbing portion 410 is arranged opposite the housing 100, thereby further protecting the carrier 200 and the housing 100 through the third shock absorbing portion 410.

[0115] The stepped structure can also ensure the structural stability and shock absorbing function stability of the second shock absorbing assembly 400 .

[0116] like Figure 9 As shown, in some embodiments, optionally, the second shock absorbing assembly 400 further includes: a fifth shock absorbing portion 430, the fifth shock absorbing portion 430 is arranged on the fourth shock absorbing portion 420, the fifth shock absorbing portion 430 is arranged opposite to the first shock absorbing assembly 300, and the fifth shock absorbing portion 430 and the fourth shock absorbing portion 420 are distributed in a stepped manner.

[0117] The fifth shock absorbing part 430 is provided on the fourth shock absorbing part 420 , so that a multi-step structure is formed on the second shock absorbing assembly 400 , further reducing the sticking phenomenon between the second shock absorbing assembly 400 and the second shock absorbing member 320 .

[0118] Of course, in other embodiments, more levels of stepped structures may be provided, which will not be described in detail here.

[0119] In this embodiment, the fifth shock absorbing portion 430 is disposed opposite the second portion 322 of the second shock absorbing element 320. The soft-to-soft interaction between the fifth shock absorbing portion 430 and the second portion 322 provides a first-level buffer. Because the housing 120 avoids the second portion 322, the fifth shock absorbing portion 430 and the second portion 322 have a good buffering effect. The fourth shock absorbing portion 420 is disposed opposite the first portion 321 of the second shock absorbing element 320. The soft-to-soft interaction between the fourth shock absorbing portion 420 and the first portion 321 provides a second-level buffer. The third shock absorbing portion 410 is disposed opposite the housing 120, providing a third-level buffer.

[0120] Combine Figure 2 and Figure 13 As shown, in some embodiments, optionally, a second shock absorbing assembly 400 is provided on the side of the carrier 200 , so that a portion of the second shock absorbing assembly 400 is located between the side of the carrier 200 and the side of the housing 100 .

[0121] A portion of the second shock absorbing assembly 400 extends to the side of the carrier 200 , preventing the side of the carrier 200 from directly contacting the side of the housing 100 .

[0122] Although the carrier 200 does not need to move directly perpendicular to the first direction Z, when the electronic device is impacted or dropped, the carrier 200 may deviate a certain amount relative to the housing 100, which may cause the carrier 200 to strike the housing 100. Therefore, a portion of the second shock-absorbing assembly 400 is disposed between the side of the carrier 200 and the side of the housing 100 to prevent the side of the carrier 200 from directly striking the side of the housing 100, prevent rigid contact between the carrier 200 and the housing 100, and reduce the damage rate of the carrier 200 and the housing 100.

[0123] Combine Figure 16 and Figure 17 As shown, in some embodiments, optionally, the first end surface 440 of the second shock absorbing assembly 400 faces the side of the housing 100 , and a circumferential edge of the first end surface 440 is provided with a chamfered corner 450 .

[0124] The end face of the second shock absorbing assembly 400 facing the side of the shell 100 is set as the first end face 440, and the circumferential edge of the first end face 440 is processed and formed with a chamfer 450. When the carrier 200 moves toward the side of the shell 100, the first end face 440 contacts the side of the shell 100. The chamfer 450 can reduce the contact area between the first end face 440 and the shell 100, thereby reducing the adhesion force between the first end face 440 and the shell 100, and avoiding the occurrence of sticking between the first end face 440 and the shell 100.

[0125] In other embodiments, a recessed structure may be formed on the first end surface 440 . The recessed structure may reduce the contact area between the first end surface 440 and the housing 100 , thereby reducing the adhesion between the first end surface 440 and the housing 100 .

[0126] In other embodiments, the first end surface 440 is a spherical surface, so as to reduce the contact area between the first end surface 440 and the housing 100 .

[0127] Combine Figure 13 、 Figure 14 、 Figure 16 and Figure 18 As shown, in some embodiments, optionally, second shock absorbing assemblies 400 are provided on both sides of the carrier 200 along the second direction X, and a second shock absorbing assembly 400 is provided on one side of the carrier 200 along the third direction Y. The second direction X and the third direction Y are both perpendicular to the first direction Z. The drive motor 10 further includes a ball bearing 600. The ball bearing 600 is located between the other side of the carrier 200 and the housing 100 along the third direction Y. The carrier 200 moves relative to the carrier 200 along the first direction Z via the ball bearing 600.

[0128] The carrier 200 can move relative to the housing 100 along the first direction Z. A ball 600 is provided between the carrier 200 and the housing 100 to reduce the friction force on the carrier 200 during movement and ensure the stability and smoothness of the movement of the carrier 200 relative to the housing 100.

[0129] Along the second direction X, the second shock-absorbing assembly 400 is provided on both sides of the carrier 200. Therefore, when the carrier 200 shakes along the second direction X, both sides of the carrier 200 can be cushioned by the second shock-absorbing assembly 400. Along the third direction Y, the second shock-absorbing assembly 400 is provided on one side of the carrier 200, and the balls 600 are distributed on the other side of the carrier 200. To ensure that the carrier 200 can slide stably along the balls 600, the second shock-absorbing assembly 400 is not provided on the other side of the carrier 200 to prevent the balls 600 from contacting the second shock-absorbing assembly 400 of the soft structure.

[0130] Combine Figure 14 、 Figure 15 、 Figure 16 and Figure 17 As shown, the second shock absorbing assembly 400 includes a third shock absorbing member 480 and a fourth shock absorbing member 490 . The third shock absorbing member 480 protrudes from the carrier 200 in two adjacent directions, and the fourth shock absorbing member 490 protrudes from the carrier 200 in only a single direction.

[0131] Combine Figure 16 、 Figure 17 and Figure 19As shown, in some embodiments, optionally, a part of the second shock absorption assembly 400 protrudes out of the side of the carrier 200, and a second hollow cavity 460 is arranged on the part of the second shock absorption assembly 400 protruding out of the side of the carrier 200.

[0132] The carrier 200 moves towards the side of the housing 100, so that the second hollow cavity 460 provides space for the deformation of the second shock absorption assembly 400 when the deformation occurs, which can improve the deformation amount of the second shock absorption assembly 400 and is beneficial to improve the buffering effect of the second shock absorption assembly 400 on the carrier 200.

[0133] Exemplarily, the second hollow cavity 460 can be a closed cavity or a cavity with an open side.

[0134] In combination with Figure 20 and Figure 21 As shown, in some embodiments, optionally, the carrier 200 comprises a support 210, a carrier 220 and a movable piece 230, the carrier 220 is connected to the support 210, and the second shock absorption assembly 400 is arranged on the carrier 220. The movable piece 230 is located between the support 210 and the carrier 220, and the movable piece 230 is capable of moving along the second direction X and the third direction Y relative to the support 210. The movable piece 230 is used for carrying a lens, and a part of the second shock absorption assembly 400 protrudes out of the carrier 220 towards the movable piece 230.

[0135] The support 210 and the carrier 220 define a movement space, and the movable piece 230 is capable of moving along the second direction X and the third direction Y in the movement space. The lens is mounted on the movable piece 230, and thus the movable piece 230 drives the lens to move along the second direction X and the third direction Y, thereby realizing the anti-shake function of the lens.

[0136] The second shock absorption assembly 400 protrudes out of the carrier 220 towards the movable piece 230, and when the movable piece 230 moves relative to the carrier 220, the movable piece 230 can abut against the second shock absorption assembly 400. The second shock absorption assembly 400 plays a buffering role on the movable piece 230, reduces the impact sound when the movable piece 230 moves, and can also reduce the damage rate of the movable piece 230.

[0137] In combination with Figure 20 , Figure 21 and Figure 22 As shown, in some embodiments, optionally, a third hollow cavity 470 is arranged on the second shock absorption assembly 400, and the third hollow cavity 470 protrudes out of the inner wall of the carrier 220 towards the movable piece 230.

[0138] The movable part 230 moves within the support 210 and the bearing part 220 so that when the second shock absorbing assembly 400 is deformed, 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 beneficial to improving the buffering effect of the second shock absorbing assembly 400 on the movable part 230.

[0139] Exemplarily, the third hollow cavity 470 may be a closed cavity or a cavity with open sides.

[0140] In the above embodiment, the first shock absorbing assembly 300 and the second shock absorbing assembly 400 can be flexibly adjusted by replacing elastic materials of different hardness to achieve a balance between performance and cushioning effect.

[0141] In the above embodiments, the characteristics of the buffering and shock absorbing structure include contact characteristics, buffering and shock absorbing characteristics, and second-order or multi-order collision protection characteristics.

[0142] The contact feature is used to increase the buffer space and ensure stable performance to avoid startup delays caused by sticking.

[0143] The cushioning and shock-absorbing features are achieved by using low-hardness elastic material contact and the elastic deformation of the elastic drum surface / hollow cylinder to absorb shock, thereby increasing the cushioning and reducing the impact sound.

[0144] The second-step or multi-step bosses serve as limit protection to ensure the structure and function are intact.

[0145] The entire impact shock absorption process includes: point contact, surface contact, elastic body deformation shock absorption, and second-order / multi-order stop surface protection.

[0146] This embodiment improves the structure of the drive motor 10 by providing a buffering and shock-absorbing structure at the internal collision site. This absorbs and disperses the impact energy, reducing the impact force during collision. This effectively reduces the impact noise generated by the drive motor 10 during operation, improves the quietness of the camera, and enhances the user experience. It also helps protect the integrity of the internal motion structure and improves its reliability in impact resistance.

[0147] like Figure 23 As shown, in an embodiment of the present application, a camera module is proposed, including a lens 700 and a 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 effect as in any of the above embodiments, which will not be repeated here.

[0148] In a possible application, the lens 700 is disposed on the carrier 200 .

[0149] like Figure 23As shown, in an embodiment of the present application, an electronic device is proposed, including: a power supply 800, a lens 700 and a driving motor 10 in any of the above embodiments, the power supply 800 is electrically connected to the driving motor 10, the lens 700 is arranged on the driving motor 10, and the electronic device can achieve the same technical effects as in any of the above embodiments, which will not be repeated here.

[0150] Electronic devices include any of the following: mobile phones, tablet computers, smart wearable devices, and e-books.
