The present application is described below with reference to specific embodiments in conjunction with the accompanying drawings:

as shown in fig. 1-7, the present embodiment provides an image capturing module, which includes a lens 100 and a motor 200 driving the lens 100 to stretch and retract, wherein a gap is formed between a housing 201 of the motor 200 and a lens barrel of the lens 100 to reserve a stretching space of the lens 100, and dust easily enters the motor 200 from the gap and even moves onto an optical filter, thereby affecting imaging of the camera. Therefore, in this embodiment, the camera module further includes the sealing sleeve 300, the sealing sleeve 300 is sleeved at the upper end of the lens barrel of the lens 100, the bottom surface of the sealing sleeve 300 is attached to the top surface of the housing 201 of the motor 200, it can be understood that the sealing sleeve 300 covers and shields the gap between the lens barrel and the housing 201 of the motor 200, dust or other impurities can be effectively prevented from entering the motor 200 through the gap, the sealing sleeve 300 is connected with the lens barrel in a sleeved mode, under the condition of ensuring connection tightness, the installation efficiency is high, and the outer wall of the lens 100 cannot be worn and influenced.

In the storage or transportation process of the camera module, the lens 100 of the camera module faces upwards, the bottom surface of the sealing sleeve 300 is attached to the top surface of the shell 201, dust or other impurities cannot enter the shell 201 easily through the gap between the sealing sleeve 300 and the shell 201, the dustproof effect is good, meanwhile, the sealing sleeve 300 is not connected with the motor 200, the sealing sleeve 300 does not affect the expansion and contraction of the lens 100, the sealing sleeve 300 does not need to be detached, and the sealing sleeve 300 can also play a dustproof role in the process of installing the camera module to a terminal.

As one embodiment, the sealing sleeve 300 is a rubber sealing sleeve or a silicone sealing sleeve, and the rubber or silicone sealing sleeve is soft in material and has a strong capability of recovering to an initial state after elastic deformation. Referring to fig. 6, the sealing sleeve 300 is cylindrical, and the height of the telescopic barrel is h ₁ When the lens 100 is extended to the limit height, the distance between the bottom end of the sealing sleeve 300 and the top surface of the housing 201 of the motor 200 is h ₂ Let h ₁ ≥h ₂ When the lens 100 is restored to the initial position, the sealing sleeve 300 is deformed by extrusion, the sealing sleeve 300 is closely attached to the housing 201 of the motor 200, and the dustproof effect is good. Meanwhile, the density of rubber or silica gel is low, and correspondingly, the weight of the sealing sleeve 300 is low, so that the pressure of the motor 200 for driving the lens 100 to move can be reduced.

Further, the sealing sleeve 300 is in the shape of a truncated cone, i.e. sealingThe bottom edge of the sleeve 300 is thinner, and is easy to deform, so that the sealing performance of the sealing sleeve 300 is improved when the lens 100 is in the initial state, and as another implementation manner, the sealing sleeve 300 can be made to be thin-walled, and at the moment, the height value of the telescopic lens barrel is h ₃ The height difference h between the bottommost end of the joint of the sealing sleeve 300 and the lens barrel and the bottommost end of the sealing sleeve 300 in a natural state ₄ Let 0 < h ₃ ≤h ₄ It can be understood that even if the lens barrel extends to the limit height, the bottom end of the sealing sleeve 300 can still contact with the top surface of the housing 201 of the motor 200, when the lens barrel is retracted to the initial state, since the side wall of the sealing sleeve 300 is thin, the sealing sleeve 300 will deform, so that part of the inner wall of the sealing sleeve is attached to the top surface of the housing 201, i.e. the contact area between the sealing sleeve 300 and the housing 201 is enlarged, the sealing performance is improved, the dustproof effect is good, i.e. no matter whether the lens 100 is in the use state, the sealing sleeve 300 can play a dustproof role, and the thin-walled sealing sleeve 300 has low weight, so that the requirement on the power of the motor 200 can be reduced. Further, the bottom end of the sealing sleeve 300 is provided with an inclined plane 331, when the lens 100 is in an initial state, the inclined plane 331 is attached to the top surface of the motor 200, and the contact area is increased through the contact of the surfaces, so that the dustproof effect is improved.

Further, referring to fig. 2, 4 and 5, the sealing sleeve 300 includes a socket portion 310, a telescopic portion 320 and a lap portion 330 sequentially arranged along a bus direction, the inner diameter of the socket portion 310 is smaller than that of the lap portion 330, the socket portion 310 is sleeved at the upper end of the lens barrel, the lap portion 330 is attached to the top surface of the motor 200, and flexibility of the sealing sleeve 300 in deformation is improved through the telescopic portion 320, so that in the process of telescopic lens 100, the inclined surface 331 at the bottom end of the sealing sleeve 300 can keep surface contact with the top surface of the motor 200.

The socket part 310 is annular, and the annular inner wall surface of the socket part 310 is tightly attached to the lens barrel, so that the contact area between the socket part 310 and the lens barrel is increased, the friction between the inner wall of the socket part 310 and the outer wall of the lens barrel is increased, and the tightness between the sealing sleeve 300 and the lens barrel is further improved. One end of the sleeving part 310 is connected with one end of the telescopic part 320, referring to fig. 4, the bottom end of the sleeving part 310 is connected with the telescopic part 320, so that the sleeving part 310 is conveniently sleeved on a lens barrel when the sealing sleeve 300 is installed, wherein the bottom end of the sleeving part 310 is the end of the sleeving part close to the motor 200, and the sleeving part 310 can provide supporting force for the telescopic part 320 when the telescopic part 320 is compressed in such a connection mode, so that the lap joint part 330 is kept in surface contact with the top surface of the motor 200 in the compression process of the sealing sleeve 300.

Referring to fig. 7, as an alternative embodiment, the telescopic portion 320 is disposed between the socket portion 310 and the overlap portion 330, one end of the telescopic portion is connected to one end of the socket portion near the motor, the other end is connected to the overlap portion, the thickness of the telescopic portion 320 is smaller than the thickness of the socket portion 310 and the average thickness of the overlap portion 330, and the telescopic portion 320 with a smaller thickness is softer and more easily deformed by using the characteristics of rubber materials, so that the overlap portion 330 is kept in contact with the top surface of the motor 200 under the condition that the telescopic amplitude of the lens 100 is lower.

Further, in this embodiment, at least one fold ring 321 is disposed on the expansion portion 320, referring to fig. 2 and 4, the fold ring 321 is in a wavy shape along the axial section of the sealing sleeve 300, and the fold portion of the sealing sleeve 300 is stretched during the process of driving the lens 100 to extend, so that the length of the fold portion increases, and the expansion width of the lens 100 increases under the condition that the overlap portion 330 is kept in contact with the top surface of the motor 200. Further, in the present application, the telescopic portion 320 of the sealing sleeve 300 sleeved on the lens barrel is in a compressed state, and when the telescopic portion 320 is compressed, the bottom surface of the overlap portion 330 is attached to the top surface of the housing 201 of the motor 200. Referring to fig. 5, specifically, when the lens 100 is extended to a limited height, the telescopic portion 320 is still in a compressed state, and at this time, the telescopic portion 320 has an elastic force that returns to a natural state, and the elastic force is transferred to the overlap portion 330 and finally acts on the top surface of the housing 201, and since the whole sealing sleeve 300 is in a frustum shape, the elastic force generated by compression of the telescopic portion 320 will enable a stronger friction force between the overlap portion 330 and the top surface of the housing 201, so that the bottom surface of the overlap portion 330 and the top surface of the motor 200 remain closely attached, and good sealing performance is maintained. Referring to fig. 4, it can be understood that when the lens 100 is in an initial state, i.e., the lens 100 is in a state where it cannot be further retracted, the compression part is further compressed, the elastic force of the compression part returning to the natural state is greater, the friction between the bottom surface of the overlap part 330 and the top surface of the motor 200 is greater, and the sealing performance is better. It should be noted that, referring to fig. 1, when the telescopic portion 320 is compressed, the outer diameter of the overlap portion 330 is smaller than the width of the housing 201 of the motor 200, and even if the lens 100 is in the initial state, the outer diameter of the overlap portion 330 is smaller than the width of the top surface of the motor 200, so as to ensure the sealing effect of the sealing sleeve 300.

Considering that the taper of the sealing sleeve 300 changes during the expansion and contraction process of the lens 100, in order to ensure that the bottom surface of the overlap portion 330 is attached to the top surface of the motor 200, referring to fig. 4 and 5, in this embodiment, two fold rings 321 are disposed on the expansion and contraction portion 320, the fold rings 321 are not only expandable but also bendable, and by disposing two fold rings 321 on the sealing sleeve 300, the difficulty in bending the expansion and contraction of the lens 320 is reduced, so that the expansion and contraction of the lens 100 is facilitated, and the conduction of the elastic force of the fold rings 321 is not affected when the fold rings 321 are compressed.
