In this preferred embodiment of the present application, the second lens group 112 is a movable group, disposed on the carrier 32 of the driving assembly 30. The driving mechanism 33 drives the carrier 32, causing the second lens group 112 to move along the optical axis, thereby achieving optical zoom.
[0064] The base 31 has a receiving space 310, wherein the lens group 11 and the reflective component 40 of the lens assembly 10 are disposed in the receiving space 310 of the base 31. The imaging component 20 is fixed to one of the outer sides of the base 31. The driving mechanism 33 of the driving component 30 is disposed on the base 31, wherein the driving mechanism 33 may be, but is not limited to, a magnetic driving device composed of a coil and a magnet pair, a piezoelectric actuator, or an SMA actuator.

[0067] The driving mechanism 30 further includes at least one buffer structure 35, wherein the buffer structure 35 is disposed on the carrier 32 to reduce or mitigate noise generated by collision during the movement of the carrier 32. In this preferred embodiment of the present application, the driving mechanism 33 drives the carrier 32 to move relative to the base 31 along the optical axis of the lens group 11, wherein there is at least one movable gap 301 between the carrier 32 and the base 31 along the optical axis of the lens group 11, and at least a portion of the buffer structure 35 protrudes from the movable gap 301. When the movement of the carrier 32 along the optical axis exceeds a preset stroke, the buffer structure 35 protruding from the carrier 32 first collides with the base 31, thereby avoiding direct collision between the carrier 32 and the base 31. That is, the buffer structure 35 absorbs and mitigates the impact force, thereby reducing the noise of the impact.
[0068] Preferably, in this preferred embodiment of the present application, the movable gap 301 is formed at one end of the carrier 32 facing the object side and at one end facing the image side, and the movable gap 301 is formed at both ends of the carrier 32.

The carrier 32 further includes a carrier connecting portion 323, wherein the carrier connecting portion 323 connects the carrier bottom 321 and the carrier sides 322, and the carrier connecting portion 323 is located at the ends of the carrier bottom 321 and the carrier sides 322. It is worth mentioning that the carrier bottom 321, the carrier sides 322, and the carrier connecting portion 323 of the carrier 32 form a receiving space for accommodating the second lens group 112, that is, the second lens group 112 is fixed in the receiving space of the carrier 32.
[0070] The base 31 includes a base body 311 and a stop structure 312, wherein the stop structure 312 is integrally formed in the base body 311.

It is worth mentioning that an movable gap 301 is formed between the carrier 32 and the stop structure 312 of the base 31. More specifically, the movable gap 301 is formed between one end of the carrier 32 and the stop structure 312. The gear shift structure 312 further includes a first gear shift member 3121 and a second gear shift member 3122, wherein the first gear shift member 3121 is located on the object side of the second gear shift member 3122, and the movable gap 301 is formed between the carrier 32 and the first gear shift member 3121; and / or the movable gap 301 is formed between the carrier 32 and the second gear shift member 3122.
[0071] The buffer structure 35 is fixed to the two carrier sides 322 of the carrier 32, so that when the carrier 32 exceeds the preset stroke, the carrier 32 can collide with the stop structure 312 of the base 31 in the direction along the optical axis through the buffer structure 35 fixed to the carrier side 322. The impact force is absorbed and mitigated by the buffer structure 35, thereby reducing the noise of the impact.
[0072] like Figure 3 and Figure 4As shown, the buffer structure 35 includes a structural member 351 and at least one flexible member 352, wherein the structural member 351 and the flexible member 352 are connected, the flexible member 352 is supported by the structural member 351, and is held in the movable gap 301 between the carrier 32 and the stop structure 312 of the base 31. The structural member 351 of the buffer structure 35 is disposed on the carrier side 322 of the carrier 32, wherein the flexible member 352 of the buffer structure 35 protrudes from the structural member 351 toward the movable gap 301 on the outer side of the carrier side 322.
[0073] In this preferred embodiment of the present application, the buffer structure 35 includes two flexible members 352, wherein the flexible members 352 are symmetrically disposed at both ends of the structural member 351.
[0074] The flexible component 352 has a buffer cavity 3520, which can increase the elasticity of the flexible component 352, enabling it to better absorb and disperse energy when subjected to impact, thereby improving the overall buffering effect; it can also reduce stress concentration of the flexible component 352 when subjected to impact, extending its service life; in addition, the buffer cavity 3520 of the flexible component 352 can also help reduce noise by absorbing and isolating sound waves, thereby improving the acoustic performance of the product.
[0075] The structural component 351 is fixed to the carrier 32. It is made of a rigid material, such as metal or plastic, and is suitable for supporting the flexible component 352 and maintaining the shape of the buffer structure. The flexible component 352 is made of a flexible material such as silicone or sponge, which is suitable for deformation and absorbs impact, thereby reducing noise.

As an example, in a specific example of this application, the structural member 351 includes two longitudinal structural frames 3512, and the longitudinal structural frames 3512 are disposed at both ends of the transverse structural frame 3511. Preferably, the transverse structural frame 3511 is substantially parallel to the optical axis of the lens group 11, and the longitudinal structural frame 3512 is substantially perpendicular to the optical axis of the lens group 11.
[0077] The two ends of the transverse structural frame 3511 of the structural member 351 are connected to the longitudinal structural frame 3512, wherein the transverse structural frame 3511 is located at the top of the longitudinal structural frame 3512, and the longitudinal structural frame 3512 supports the transverse structural frame 3511.

That is, the buffer cavity 3520 is spaced between the movable gap 301 between the carrier side portion 322 of the carrier 32 and the base 31. When subjected to impact, it can better absorb and disperse energy, thereby improving the overall buffering effect. It can also reduce the stress concentration of the side flexible member 3521 when subjected to impact, thereby extending its service life. In addition, the buffer cavity 3520 of the flexible member 352 can also help reduce noise by absorbing and isolating sound waves, thereby improving the acoustic performance of the product.
[0079] In this preferred embodiment of the present application, the buffer structure 35 has two side flexible members 3521, and the side flexible members 3521 are symmetrically arranged on both sides of the structural member 351.

[0080] It is worth mentioning that the buffer cavity 3520 of the flexible member 352 is a cavity formed in the side flexible member 3521. When the side flexible member 3521 deforms, the buffer cavity 3520 provides buffering to facilitate the dispersion of energy.
[0081] The side flexible member 3521 of the flexible member 352 further includes a deformable portion 3522 and at least one fixed portion 3523 integrally extending from the end of the deformable portion 3522, wherein a buffer cavity 3520 is formed between the fixed portion 3523 and the deformable portion 3522.

When the flexible member 352 is subjected to impact or collision, the deformable portions 3522 located on both sides of the buffer cavity 3520 can provide balanced support, which can not only improve the buffering effect, but also allow the flexible member 352 to quickly rebound after the force is removed.
[0083] The fixing portion 3523 of the side flexible member 3521 further includes a first fixing portion 35231, a second fixing portion 35232, and a fixing connection portion 35233 connecting the first fixing portion 35231 and the second fixing portion 35232, wherein the first fixing portion 35231, the second fixing portion 35232, and the fixing connection portion 35233 of the fixing portion 3523 are an integral structure. The first fixing portion 35231 extends integrally from one end of the deformable portion 3522, and the second fixing portion 35232 extends integrally from the other end of the deformable portion 3522, that is, the deformable portion 3522 is fixed to one side of the longitudinal structural frame 3512 by the fixing portion 3523.
[0084] The longitudinal structural frame 3512 is provided with mounting holes corresponding to the fixing part 3523, wherein the first fixing part 35231, the second fixing part 35232 and the fixing connection part 35233 of the fixing part 3523 are embedded in the mounting holes of the longitudinal structural frame 3512, thereby fixing the side flexible member 3521 to one side of the longitudinal structural frame 3512.
[0085] The deformable portion 3522 of the side flexible member 3521 extends integrally from the fixed portion 3523 and protrudes outward. The deformable portion 3522 is located on the side away from the carrier 32 relative to the fixed portion 3523 and is opposite to the stop structure 312 of the base 31. The deformable portion 3522 further includes a first deformable unit 35221, a second deformable unit 35222, and a third deformable unit 35223 located between the first deformable unit 35221 and the second deformable unit 35222. The first deformable unit 35221, the second deformable unit 35222, and the third deformable unit 35223 are an integral structure.
[0086] The first deformation unit 35221 is connected to the first fixing portion 35231 of the fixing portion 3523, and the second deformation unit 35222 is connected to the second fixing portion 35232 of the fixing portion 3523. The first deformation unit 35221 and the second deformation unit 35222 are located on both sides of the third deformation unit 35223 and protrude outwards, i.e., the first deformation unit 35221 and the second deformation unit 35222 protrude in a direction away from the carrier 32. The third deformation unit 35223 is located between the first deformation unit 35221 and the second deformation unit 35222 and protrudes inwards, i.e., the third deformation unit 35223 extends in a direction closer to the carrier 32. The deformation portion 3522 of the side flexible member 3521 forms an approximate "3" or approximate... The buffer cavity 3520 is in the shape of a letter. It is worth noting that the specific shape of the deformable part 3522 is merely an example and not a limitation.
[0087] The first deformation unit 35221 of the deformable portion 3522 integrally extends from the first fixing portion 35231 of the fixing portion 3523, and a compressible first buffer cavity 201 is formed between the first deformation unit 35221 and the first fixing portion 35231; the second deformation unit 35222 of the deformable portion 3522 integrally extends from the second fixing portion 35232 of the fixing portion 3523, and a compressible second buffer cavity 202 is formed between the second deformation unit 35222 and the second fixing portion 35232; the third deformation unit 35223 of the deformable portion 3522 is opposite to the fixed connection portion 35233 of the fixing portion 3523, and a compressible third buffer cavity 203 is formed between the third deformation unit 35223 and the fixed connection portion 35233. It is understood that, in this preferred embodiment of the present application, the compressible width of the third buffer cavity 203 is smaller than the compressible width of the first buffer cavity 201 or the second buffer cavity 202. It is also understood that, in this preferred embodiment of the present application, the buffer cavity 3520 is composed of the first buffer cavity 201, the second buffer cavity 202, and the third buffer cavity 203, which are interconnected.
[0088] like Figure 7 and Figure 8The diagram illustrates another optional embodiment of the side flexible member 3521 of the buffer structure described in the preferred embodiment of this application. The first deformation unit 35221 of the deformable portion 3522 integrally extends from the first fixing portion 35231 of the fixing portion 3523, and a compressible first buffer cavity 201 is formed between the first deformation unit 35221 and the first fixing portion 35231; the second deformation unit 35222 of the deformable portion 3522 integrally extends from the second fixing portion 35232 of the fixing portion 3523, and a compressible second buffer cavity 202 is formed between the second deformation unit 35222 and the second fixing portion 35232; the third deformation unit 35223 of the deformable portion 3522 is connected to the fixed connection portion 35233 of the fixing portion 3523. It is understood that in this preferred embodiment of this application, the buffer cavity 3520 is composed of mutually spaced first buffer cavities 201 and second buffer cavities 202. The deformable portion 3522 and the fixed portion 3523 of the side flexible member 3521 form two D-shaped or B-shaped buffer cavities 3520.
[0089] It is understood that the side flexible member 3521 of the above-described structure of this application helps to maintain its shape when not subjected to impact. Preferably, the dimension of the third deformation unit 35223 of the side flexible member 3521 along the direction of movement perpendicular to the carrier 32 is smaller than the dimension of the first deformation unit 35221 along the direction of movement perpendicular to the carrier 32, and smaller than the dimension of the second deformation unit 35222 along the direction of movement perpendicular to the carrier 32.
[0090] It is understood that the deformation of the buffer structure 35 in the above preferred embodiment of this application can be reduced, so that in the periscope camera module, the space reserved in the direction of motion of the moving part of the drive component 30 does not need to be too large compared with the stator part, which is conducive to reducing the size of the drive component 30.
[0091] It is worth mentioning that when the carrier 32 is driven to move toward the stop structure 312 of the base 31, the side flexible member 3521 impacts the stop structure 312 of the base 31 before the carrier 32. During this impact, the buffer cavity 3520 of the side flexible member 3521 is compressed, with the third buffer cavity 203 corresponding to the third deformation unit 35223 being fully compressed first, and the third deformation unit 35223 contacting the fixed connection portion 35233 or the longitudinal structural frame 3512 first. The first buffer cavity 201 corresponding to the first deformation unit 35221 and the second buffer cavity 202 corresponding to the second deformation unit 35222 are then fully compressed. Therefore, before the carrier 32 collides with the stop structure 312 of the base 31, the side flexible member 3521 of the buffer structure 35 can form a two-stage buffer, further reducing the impact noise. The first stage significantly absorbs the impact force, and the second stage absorbs a smaller amount of impact force. It should be understood that during the compression of the third buffer cavity 203, the first buffer cavity 201 and the second buffer cavity 202 may also be partially compressed. However, the deformation of the third buffer cavity 203 is greater than that of the first buffer cavity 201 and the second buffer cavity 202, and the deformation of the third buffer cavity 203 is completed before the first buffer cavity 201 and the second buffer cavity 202 are fully compressed.
[0092] As an example, in a specific example of this application, the third buffer cavity 203 corresponding to the third deformable portion 35223 has a lateral dimension of 0.2mm-1mm, preferably 0.3mm-0.7mm, including the end values. Within the above range, noise can be effectively reduced, and the shape of the side flexible member 3521 can be maintained when not subjected to impact.
[0093] It should be noted that within the rated stroke of the drive assembly 30, the side flexible member 3521 will not contact the stop structure 312 of the base 31. That is, the arrangement of the side flexible member 3521 will not affect the normal movement of the carrier 32, and within the rated stroke of the drive assembly 30, the side flexible member 3521 and the stop structure 312 of the base 31 are kept at a distance.
[0094] The flexible member 352 further includes at least one top flexible member 3524, wherein the top flexible member 3524 is disposed on the transverse structural frame 3511 of the structural member 351, and the top flexible member 3524 is spaced between the carrier 32 and the housing 34. The top flexible member 3524 can prevent the carrier 32 from directly colliding with the housing 34 when the carrier 32 moves away from the base 31.
[0095] The transverse structural frame 3511 of the structural member 351 is provided with corresponding openings, wherein the top flexible member 3524 is fixed at the opening of the transverse structural frame 3511 and the top flexible member 3524 is embedded in the transverse structural frame 3511 to increase the bonding strength.
[0096] It should be understood that when the drive assembly 30 includes two or more carriers 32, the active gap 301 is formed between two adjacent carriers 32, that is, the buffer structure 35 is disposed in one of the carriers 32 and spaced apart from the other adjacent carrier 32. When one of the carriers 32 is driven, the buffer structure 35 disposed in the carrier 32 impacts the other adjacent carrier 32.
[0097] like Figure 9 As shown, the buffer structure 35 is mounted on the carrier side 322 of the carrier 32. The carrier side 322 has at least one insertion slot 3221 corresponding to the structural member 351 of the buffer structure 35. The insertion slot 3221 is formed at the end of the carrier side 322, and the longitudinal structural frame 3512 of the structural member 351 of the buffer structure 35 can be inserted into the insertion slot 3221. It is worth noting that the insertion slot 3221 of the carrier 32 is adapted to accommodate the longitudinal structural frame 3512 of the structural member 351 and the fixing portion 3523 of the flexible member 352.
[0098] The insertion groove 3221 of the carrier side portion 322 extends longitudinally from the top end of the carrier side portion 322 to the bottom end of the carrier side portion 322. The carrier side portion 322 is further provided with an adhesive groove 3222, which is formed at the top end of the carrier side portion 322. When the longitudinal structural frame 3512 of the structural member 351 of the buffer structure 35 is inserted into the insertion groove 3221, adhesive can be applied in the adhesive groove 3222 to fix the structural member 351 of the buffer structure 35 to the carrier 32.
[0099] The insertion slot 3221 of the carrier side 322 is a slot structure with a large opening at the top and a gradually decreasing opening downwards. The top opening of the insertion slot 3221 is larger than the longitudinal structural frame 3512 of the structural member 351. After the longitudinal structural frame 3512 of the structural member 351 is inserted into the insertion slot 3221, glue can be further applied from the top opening of the insertion slot 3221 to reinforce the structure. It is understood that in this preferred embodiment of the application, the gradual decrease in the opening of the insertion slot 3221 of the carrier side 322 from top to bottom facilitates the insertion of the longitudinal structural frame 3512 of the structural member 351 and makes glue application easier. It is worth noting that the height of the glue does not exceed the height of the top flexible member 3524.
[0100] The top of the carrier side portion 322 is further provided with a groove corresponding to the top flexible member 3524. When the structural member 351 is installed onto the carrier side portion 322, the top flexible member 3524 is correspondingly installed above the groove. It is worth mentioning that the lateral dimension of the groove in the carrier side portion 322 is larger than the dimension of the lower part of the top flexible member 3524 in the lateral direction, so as not to affect the overall installation accuracy of the buffer structure 35.
[0101] like Figure 10 The above-described preferred embodiment of the buffer structure 35 is another optional implementation thereof, wherein the buffer structure 35 further includes at least one buffer member 353, wherein the buffer member 353 is disposed on the stop structure 312 of the base 31, and the buffer member 353 is opposite to the side flexible member 3521, that is, the buffer member 353 and the side flexible member 3521 are aligned. When the carrier 32 is driven to move toward the stop structure 312 of the base 31, the side flexible member 3521 disposed on the carrier 32 collides with the buffer member 353, avoiding collision between the carrier 32 and the base 31, thereby reducing the noise generated by the collision.
[0102] Preferably, in this preferred embodiment of the present application, the buffer 353 is made of silicone or sponge. More preferably, the buffer 353 is fixed to the inner side of the first stop member 3121 and / or the second stop member 3122 of the stop structure 312. The buffer 353 has a wavy buffer surface, wherein the buffer surface faces the side flexible member 3521.
[0103] like Figure 11The diagram illustrates a specific embodiment of a buffer structure 35A according to another preferred embodiment of this application. The buffer structure 35A includes a structural member 351A and a side flexible member 3521A disposed on the structural member 351A. It is worth noting that in this preferred embodiment of the application, the buffer structure 35A is disposed on the side of the carrier 32 facing the first stop member 3121 of the base 31 and / or on the side facing the second stop member 3122 of the base 31. That is, in this preferred embodiment, the buffer structure 35A can be disposed on one or both sides of the carrier 32.
[0104] Unlike the first preferred embodiment described above, the lateral flexible member 3521A is disposed at one end of the structural member 351A. Specifically, the structural member 351A includes a transverse structural frame 3511A and a longitudinal structural frame 3512A disposed at the end of the transverse structural frame 3511A, and the longitudinal structural frame 3512A is substantially perpendicular to the transverse structural frame 3511A. It is worth mentioning that, in this preferred embodiment of the present application, one end of the transverse structural frame 3511A of the structural member 351A is connected to the longitudinal structural frame 3512A, wherein the transverse structural frame 3511A is located at the top of the longitudinal structural frame 3512A, and the longitudinal structural frame 3512A supports the transverse structural frame 3511A. As an example, the structural member 351A is an L-shaped bracket, wherein the structural member 351A is fixed to the side of the carrier 32 facing the first stop member 3121 and / or the side facing the second stop member 3122.
[0105] The structure of the side flexible member 3521A is the same as that of the side flexible member 3521 in the preferred embodiment described above, and will not be described in detail here.
[0106] like Figure 12 The driving component 30B shown in another preferred embodiment of this application differs from the above preferred embodiment in that it has a buffer structure 35B, wherein the buffer structure 35B is disposed on the stop structure 312 of the base 31, and the buffer structure 35B and the carrier 32 are separated by the movable gap 301, that is, the buffer structure 35B corresponds to one end of the carrier 32.
[0107] Specifically, the buffer structure 35B includes a structural member 351B and a side flexible member 3521B disposed on the structural member 351B. The side flexible member 3521B is disposed at one end of the structural member 351B. The structural member 351B includes a transverse structural frame 3511B and a longitudinal structural frame 3512B disposed at the end of the transverse structural frame 3511B, and the longitudinal structural frame 3512B is substantially perpendicular to the transverse structural frame 3511B. It is worth mentioning that, in this preferred embodiment of the present application, one end of the transverse structural frame 3511B of the structural member 351B is connected to the longitudinal structural frame 3512B, wherein the transverse structural frame 3511B is located at the top of the longitudinal structural frame 3512B, and the longitudinal structural frame 3512B supports the transverse structural frame 3511B. As an example, the structural member 351B is an L-shaped bracket, wherein the structural member 351B is fixed to the first stop member 3121 and / or the second stop member 3122 of the base 31, and the side flexible member 3521B faces the carrier 32.
[0108] like Figure 13 The diagram shows a drive assembly 30C according to another preferred embodiment of this application. The difference from the above preferred embodiment is the buffer structure 35C, wherein the buffer structure 35C includes at least one flexible member 352C and at least one buffer member 353C. The flexible member 352C is disposed on the carrier side 322 of the carrier 32, and the buffer member 353C is disposed on the stop structure 312 of the base 31. The flexible member 352C and the buffer member 353C are aligned.
[0109] The flexible element 352C is fixed to the carrier side 322 of the carrier 32. A compressible buffer cavity 3520C is formed between the flexible element 352C and the carrier side 322. When the carrier 32 is driven, when the flexible element 352C collides with the buffer element 353C, the buffer cavity 3520C formed between the flexible element 352C and the carrier side 322 can buffer the collision pressure and reduce noise.
[0110] The flexible member 352C includes a side flexible member 3521C and a top flexible member 3524C, wherein the side flexible member 3521C is disposed on the side of the carrier side portion 322 facing the stop structure 312, and the top flexible member 3524C is disposed at the top of the carrier side portion 322. It is worth noting that the side flexible member 3521C and the top flexible member 3524C of the flexible member 352C are an integral structure. Preferably, the flexible member 352C is integrally formed on the carrier side portion 322 of the carrier 32. Optionally, the flexible member 352C is fixed to the carrier side portion 322 of the carrier 32 by adhesive bonding.
[0111] The buffer 353C is disposed on the inner side of the stop structure 312 of the base 31, wherein the buffer 353C is fixed on the inner side of the stop structure 312 by integral molding or adhesive bonding.
[0112] The side flexible member 3521C of the flexible member 352C is facing the buffer member 353C, wherein the outer surface of the side flexible member 3521C facing the buffer member 353C is wavy; the outer surface of the buffer member 353C facing the side flexible member 3521C is wavy.
[0113] like Figure 14 The diagram shows another optional embodiment of the side flexible member 3521 of the buffer structure described in the preferred embodiment of this application. The difference from the preferred embodiment is that the side flexible member 3521 is a solid structure. It is understood that the side flexible member 3521 can provide a buffering effect while reducing deformation, thus allowing the space reserved in the direction of motion of the mover relative to the stator in the periscope camera module to be less than excessively large.
