In some examples, the dust-proof structure 40 may be attached only to the first bottom surface 211, or the dust-proof structure 40 may be attached only to the second bottom surface 31. By connecting the dustproof structure 40 to the first bottom surface 211 or the second bottom surface 31, the dustproof structure 40 can be prevented from blocking the relative movement between the driving structure 22 and the housing 21, which may affect the normal use of the motor 20.

In other examples, the dust-proof structure 40 may connect the first bottom surface 211 and the second bottom surface 31 at the same time. Through the mode that dustproof construction 40 connects in first bottom surface 211 and second bottom surface 31 simultaneously, can make dustproof construction 40 play the effect of the isolated dust of better sealed to improve dustproof construction 40's dustproof effect.

In some embodiments, the mounting structure 30 is provided separately from the driving structure 22, i.e., the mounting structure 30 is additionally provided in a space between the driving structure 22 and the lens barrel 11. By adopting the mounting structure 30 which is arranged separately, the structure of the driving structure 22 or the lens barrel 11 does not need to be improved, and the improvement cost of the components is reduced. It is understood that the mounting structure 30 may be a plastic or a metal member, and is not particularly limited thereto.

Mounting structure 30 and drive structure 22, perhaps, the integrative mode that sets up of mounting structure 30 and lens cone 11, on the one hand, can improve mounting structure 30 and drive structure 22 or mounting structure 30 and lens cone 11 overall structure's stability, be favorable to the stability of module 100 of making a video recording, on the other hand need not additionally to set up mounting structure 30 and can realize the equipment of dustproof construction 40 of being convenient for, improves the utilization ratio of part, reduces the equipment of part simultaneously. It is understood that the integral arrangement may be a manner that the mounting structure 30 and the driving structure 22 are integrally formed, or a manner that the mounting structure and the driving structure are separately formed and then fixedly mounted together and are not easily separated from each other, which is not particularly limited.

The following description will be given taking an example in which the attachment structure 30 is provided separately from the drive structure 22 and the lens barrel 11.

As shown in fig. 2, 3 and 4, in some embodiments, the mounting structure 30 may be a ring-shaped bracket, and the mounting structure 30 is provided with an avoiding structure 32 corresponding to the dust-proof structure 40. Along the optical axis direction, dodge the structure and locate one side of mounting structure 30's light-emitting side, through dodging structure 32's design, can increase dustproof construction 40 along the activity space of optical axis direction, when avoiding mounting structure 30 and casing 21 to collide, influence dustproof construction 40's motion.

In some embodiments, the avoidance structure 32 comprises at least one of a chamfered structure, a stepped structure, or a funnel structure. By designing the avoiding structure 32 to be at least one of a chamfer structure, a step structure or a funnel structure, an avoiding space can be ensured to exist before the mounting structure 30 and the dustproof structure 40, and the influence on the movement of the dustproof structure 40 when the mounting structure 30 collides with the shell 21 is avoided.

Illustratively, the avoiding structure 32 is a chamfered structure, a distance D from a connection point of the dust-proof structure 40 and the avoiding structure 32 to the first inner wall surface 212 of the housing 21 in a direction perpendicular to the optical axis of the lens 10, a maximum distance of movement of the driving structure 22 toward the light exit side in the optical axis direction of the lens 10 is h, a chamfer angle of the chamfered structure is θ, and θ, D, h satisfy the following relation: tan theta is less than h/D. By defining the relationships among D, θ, and h, it is ensured that when the bypass structure 32 is a chamfered structure, the chamfered structure does not interfere with the movement of the dust-proof structure 40, and the movement of the motor 20 is not affected.

By mounting the lens barrel 11 in the mounting hole 33, the connection between the mounting structure 30 and the lens barrel 11 can be ensured. By connecting the outer wall surface 34 of the mounting structure 30 to the driving structure 22, it is ensured that the mounting structure 30 is connected between the driving structure 22 and the lens barrel 11, thereby facilitating the assembly of the dustproof structure 40. By protruding the second bottom surface 31 from the side of the driving structure 22 facing the first bottom surface 211, the mounting structure 30 can be ensured to move relative to the housing 21 under the driving of the driving structure 22, so as to adjust the distance between the first bottom surface 211 and the second bottom surface 31 along the optical axis direction of the lens 10, so that the first bottom surface 211 and the second bottom surface 31 tend to or are approximately located on the same plane, thereby facilitating the assembly of the dustproof structure 40.

In some embodiments, the attachment of the mounting structure 30 to the drive structure 22 includes at least one of a threaded connection, a glued connection, or a snap-fit connection. At least one connection mode of threaded connection, glue joint or buckle connection is adopted, so that the connection between the mounting structure 30 and the driving structure 22 is tighter, and the separation between the mounting structure 30 and the driving structure 22 is avoided.

Illustratively, the driving structure 22 has a second inner wall surface 221, when the mounting structure 30 and the driving structure 22 are connected by glue, an end surface of the mounting structure 30 facing the light incident side is a first end surface 35, the first end surface 35 and a part of the outer wall surface 34 of the mounting structure 30 together form a receiving portion 36, and the receiving portion 36 is used for receiving a glue medium connecting the mounting structure 30 and the driving structure 22. By using the manner that the first end surface 35 of the mounting structure 30 and the outer wall surface 34 together form the receiving portion 36, the glue can be dispensed on the first end surface 35, and then the glue can overflow to the space between the outer wall surface 34 and the second inner wall surface 221 of the driving structure 22 through the outer wall surface 34, so that the process of dispensing between the mounting structure 30 and the driving structure 22 is effectively simplified, and the bonding area between the mounting structure 30 and the driving structure 22 is effectively increased.

In some embodiments, a first groove 351 is formed on the first end surface 35, a first groove 341 is formed on the outer wall surface 34 of the mounting structure 30 corresponding to the first groove 351, the first groove 341 penetrates through the first end surface 35 and is communicated with the first groove 351, and the first end surface 35, the first groove 351 and the first groove 341 together form a receiving portion 36; the first groove 351 has a first wall face 3511 facing the driving structure 22, the first groove 341 has a second wall face 3411 facing the driving structure 22, and a distance between the first wall face 3511 and the second inner wall face 221 is larger than a distance between the second wall face 3411 and the second inner wall face 221 in a direction perpendicular to the optical axis of the lens. Through set up first recess 351 on first terminal surface 35, and be provided with the first cell body 341 with first recess 351 intercommunication on the outer wall 34, when the point is glued, can make gluey medium can flow to first cell body 341 along first recess 351, first cell body 341 can receive more gluey medium simultaneously to increase the area of gluing between mounting structure 30 and the drive structure 22, make the connection of the two more inseparable. Meanwhile, the distance between the first wall surface 3511 and the second wall surface 221 is limited to be larger than the distance between the second wall surface 3411 and the second wall surface 221, so that the outflow speed of the adhesive medium from the first groove 341 can be reduced, that is, the probability of overflow of the adhesive medium of the first groove 341 is reduced, the probability of the adhesive medium falling onto the dustproof structure 40 is further reduced, and the influence of the adhesive medium on the dustproof effect of the camera module is avoided.

By the foregoing, should dodge structure 32 and locate one side of mounting structure 30 towards dustproof construction 40, and should dodge structure 32 and can be the chamfer structure, it is visible, on the optical axis direction of camera lens, should dodge structure 32 and be located the below of first cell body 341, thus, the design of dodging structure 32 can also provide the direction to the gum medium that overflows from first cell body 341, thereby make the gum medium can overflow to should dodge structure 32 on, avoid the gum medium overflow to dustproof construction 40, thereby can avoid the gum medium overflow to dustproof construction and influence the condition of the dustproof effect of the module of making a video recording.

In some embodiments, the dust-proof structure 40 is an annular structure, i.e., the dust-proof structure 40 may be a dust-proof ring sheet, a dust-proof ring film, or the like. Through designing dustproof construction 40 for the loop configuration, can be so that dustproof construction 40 can avoid the logical light position of camera lens 10, guarantee the formation of image quality of the module of making a video recording.

It is understood that when the dust-proof structure 40 is connected to both the first bottom surface 211 and the second bottom surface 31, the outer ring side 41 of the dust-proof structure 40 is disposed on the first bottom surface 211, and the inner ring side 42 is disposed on the second bottom surface 31. Through setting up the outer loop side 41 of dustproof construction 40 in first bottom surface 211, the mode that inner loop side 42 set up in second bottom surface 31, can open drive structure 22 for the clearance of casing 21 and the logical light position separation of camera lens 10, guarantee that the dust that produces in the module 100 of making a video recording can fall into between the inner loop side 42 of dustproof construction 40 and outer loop side 41 and can not enter into the logical light position of camera lens 10, also can not fall into on the filter yet to the imaging quality of module of making a video recording has been avoided the dust to cause the influence.

In some embodiments, the side of the dust-proof structure 40 facing the light incident side, and/or the side facing the light emergent side, is coated with a dust-proof adhesive. That is, the dust-proof adhesive may be applied to the side of the dust-proof structure 40 facing the light incident side, or the dust-proof adhesive may be applied to the side of the dust-proof structure 40 facing the light exiting side, or the dust-proof adhesive may be applied to both the side of the dust-proof structure 40 facing the light incident side and the side facing the light exiting side. Like this, at dustproof construction 40 towards the one side of income light side, and/or, towards the one side coating dustproof glue of light-emitting side, can further carry out the separation to the dust through dustproof glue to further improve dustproof construction 40 dustproof effect.

In some embodiments, the dust-proof structure 40 may be connected to the mounting structure 30 and the driving structure 22 by thermal compression, or may be connected by coating an adhesive layer between the dust-proof structure 40 and the mounting structure 30 or the driving structure 22, which is not particularly limited in this embodiment.

It is understood that in other embodiments, the dust-proof structure 40 may be made of a material with elasticity and ductility, such as Polydimethylsiloxane (PDMS), Thermoplastic polyurethane elastomer (TPU), and nano-film, and when the housing 21 and the driving structure 22 move relatively, the dust-proof structure 40 can deform adaptively with the movement without affecting the normal use of the motor 20.

Referring to fig. 6 and 7, in some embodiments, when the first bottom surface 211 or the second bottom surface 31 is connected to the dust-proof structure 40, especially when there is a height difference between the first bottom surface 211 and the second bottom surface 31 along the optical axis, the image capturing module further includes a connecting member 50, and the connecting member 50 is connected to the second bottom surface 31 or the first bottom surface 211, so that the connecting member 50 can compensate for the height difference between the first bottom surface 211 and the second bottom surface 31 along the optical axis, and prevent dust from falling onto the filter through a gap between the dust-proof structure 40 and the second bottom surface 31 or the first bottom surface 211.

As shown in fig. 3, for example, when the second bottom surface 31 is connected to the dust-proof structure 40, the connecting member 50 is connected to the first bottom surface 211 to form a first accommodating space a with an opening facing the mounting structure 30, and one side of the dust-proof structure 40 departing from the second bottom surface 31 extends into the first accommodating space a; when the first bottom surface 211 is connected to the dust-proof structure 40 (as shown in fig. 6), the connecting member 50 is connected to the second bottom surface 31 to form a second accommodating space b with an opening facing the mounting structure 30, and one side of the dust-proof structure 40 departing from the first bottom surface 211 extends into the second accommodating space b. In this way, the dustproof structure 40 can have a sufficient moving space between the housing 21 and the connecting piece 50 or between the mounting structure 30 and the connecting piece 50, so that the path of dust from the motor to the photosensitive area of the camera module is increased, and the dustproof effect of the dustproof structure 40 is further improved.
