Embodiments of the present application provide examples of various specific processes and materials, but one of ordinary skill in the art will recognize the application of other processes and/or the use of other materials.
Generally, the camera module needs to adjust the focal length to adapt to different application scenes, when adjusting the focal length, the lens of the lens module moves along the optical axis, and in the process of movement, water or dust in the outside air can enter the inside of the camera module through gaps among components of the camera module, so that internal elements of the camera module are influenced, imaging quality is further influenced, and even the camera module is damaged. To solve this problem, the present application provides a lens module 10 (shown in fig. 1) and a terminal 100 (shown in fig. 12).
Referring to fig. 1 to 3, a lens module 10 according to an embodiment of the application includes a first component 11, a second component 12, a third component 13 and a fourth component 14. The first component 11 is formed with a receiving cavity 115, at least a portion of the second component 12 is received in the receiving cavity 115, and the second component 12 is capable of moving along the optical axis direction of the lens module 10 to extend or retract relative to the first component 11. The third part 13 is mounted between the first part 11 and the second part 12, the third part 13 being arranged to seal a first gap 119 between the first part 11 and the second part 12. The fourth part 14 is mounted to the second part 12 and moves together with the second part 12 when the second part 12 moves relative to the first part 11, and the fourth part 14 is adapted to co-seal the first gap 119 with the third part 13.
In the lens module 10 according to the embodiment of the application, the third member 13 and the fourth member 14 are disposed between the first member 11 and the second member 12, and the third member 13 and the fourth member 14 seal the first gap 119 between the first member 11 and the second member 12 together, and in the case where the second member 12 is in the retracted state, the fourth member 14 abuts against the third member 13, and/or the fourth member 14 abuts against the first member 11 to bear the lateral pressure. Under the condition that the second component 12 is in the extending state, the lateral pressure borne by the fourth component 14 disappears, so that the third component 13 and the fourth component 14 can have a better sealing effect, impurities such as water and dust are not easy to enter the accommodating cavity 115 through the first gap 119 between the first component 11 and the second component 12, elements in the accommodating cavity 115 can be well protected, and the problem that the imaging quality of the lens module 10 is reduced or even damaged due to the fact that external water or dust enters the lens module 10 is avoided.
The lens module 10 will be described in detail with reference to the accompanying drawings.
With continued reference to fig. 1 to 3, the lens module 10 includes a first component 11, a second component 12, a third component 13 and a fourth component 14.
Specifically, the first member 11 may be formed with a receiving cavity 115, and at least a portion of the second member 12 is received within the receiving cavity 115. It is understood that the second member 12 may be partially received in the receiving cavity 115, or the second member 12 may be entirely received in the receiving cavity 115. Further, the second member 12 is movable in the housing chamber 115, and the second member 12 is movable in the optical axis direction with respect to the first member 11. For example, the second part 12 may be moved towards the object side 101 with respect to the first part 11, and the second part 12 may also be moved towards the image side 102 with respect to the first part 11. The housing cavity 115 may be used to house other functional devices (such as the image sensor 19) of the lens module 10, and the first component 11 may provide protection for the functional devices housed in the housing cavity 115 so that the functional devices mounted in the housing cavity 115 are not easily damaged, and the first component 11 may be provided with a connection portion (such as a connection hole, a buckle, etc.) connected to an external structure, through which the first component 11 may be mounted on the external structure, and further the lens module 10 may be mounted on the external structure (such as the mobile phone housing 20 (shown in fig. 12), the tablet housing, the substrate assembly, etc.).
Referring to fig. 3, in some embodiments, the third component 13 is installed between the first component 11 and the second component 12, and is used for sealing a first gap 119 formed between the first component 11 and the second component 12, so that when the second component 12 moves along the optical axis direction relative to the first component 11, the first gap 119 formed between the first component 11 and the second component 12 is sealed, and the functional device accommodated in the accommodating cavity 115 is prevented from being damaged due to external impurities such as water or dust entering the lens module 10.
In some embodiments, the fourth component 14 is mounted to the second component 12, moves with the second component 12 as the second component 12 moves relative to the first component 11, and the fourth component 14 cooperates with the third component 13 to seal the first gap 119. Specifically, when the second member 12 moves (retracts) relative to the first member 11 in the direction from the object side 101 to the image side 102 of the lens module 10, the third member 13 and the fourth member 14 come closer together, and with the second member 12 in the retracted state, the fourth member 14 collides with the third member 13 and the fourth member 14 collides with the first member 11 to bear the lateral pressure; or with the second part 12 in the retracted state, the fourth part 14 only interferes with the third part 13 to withstand lateral pressure; or in the case of the second part 12 in the retracted state, the fourth part 14 only interferes with the first part 11 to withstand lateral pressure. When the second part 12 moves relative to the first part 11 along the direction from the image side 102 to the object side 101 of the lens module 10, the third part 13 and the fourth part 14 gradually move away from each other, and the lateral pressure born by the fourth part 14 disappears when the second part 12 is in the state of being completely extended. It should be noted that in some embodiments, the retracted state may be a fully retracted state or a partially retracted state.
It should be noted that, the fourth component 14 bears the lateral pressure, which is favorable for improving the dustproof and waterproof effects of the lens module 10, and avoiding the problem that the imaging effect of the lens module 10 is poor or even damaged due to the fact that external impurities such as water or dust enter the lens module 10. In one example, the lateral pressure experienced by the fourth part 14 may be generated by interference with the third part 13; in another example, the lateral pressure experienced by the fourth part 14 may be generated by interference with the first part 11; in yet another example, the lateral pressure exerted by the fourth member 14 may be caused by interference with both the first member 11 and the third member 13; in another example, the lateral pressure experienced by the fourth component 14 may also be generated by interference with other components, without limitation.
Referring to fig. 2 and 3, in some embodiments, the lens module 10 may further include a fifth component 15, where the fifth component 15 includes a driving member 151 for driving the second component 12 to move along the optical axis relative to the first component 11. Specifically, the fifth component 15 may drive the second component 12 to move toward the object side 101 and toward the image side 102 of the lens module 10 relative to the first component 11. For example, when shooting with the lens module 10 is required, the fifth component 15 may drive the second component 12 to move from the initial position toward the object side 101 of the lens module 10; when the lens module 10 is not required to be used, the fifth component 15 may drive the second component 12 to move towards the image side 102 of the lens module 10 to return to the initial position of the lens module 10.
In certain embodiments, the drive 151 has a first rotational speed during movement of the second part 12 relative to the first part 11 when the second part 12 is moved to subject the fourth part 14 to lateral pressure; the second part 12 is moved such that the fourth part 14 is not subjected to lateral pressure, the drive 151 has a second rotational speed, which is greater than the first rotational speed.
Specifically, when the second component 12 moves relative to the first component 11 in the direction from the image side 102 to the object side 101 of the lens module 10, in the case where the fourth component 14 first collides with the third component 13 and/or the fourth component 14 first collides with the first component 11, that is, when the fourth component 14 receives a lateral pressure from the third component 13 and/or from the first component 11, the driving piece 151 has a first rotation speed; with the movement of the second part 12, the driving member 151 has a second rotational speed in case the fourth part 14 becomes free from interference with the third part 13 and/or the fourth part 14 becomes free from interference with the first part 11, i.e. the fourth part 14 is not subjected to lateral pressure. When the second component 12 moves along the object side 101 to the image side 102 of the lens module 10 relative to the first component 11, the driving member 151 has a second rotation speed when the fourth component 14 does not collide with the third component 13 and/or the fourth component 14 does not collide with the first component 11, i.e. the fourth component 14 is not subjected to lateral pressure; with the movement of the second part 12, the drive 151 has a first rotational speed in case the fourth part 14 becomes in conflict with the third part 13 and/or the fourth part 14 becomes in conflict with the first part 11, i.e. the fourth part 14 is subjected to lateral pressure from the third part 13 and/or from the first part 11.
It should be noted that, the friction load and the dust-proof and water-proof effect generated during the whole process of ejecting (moving in the direction from the image side 102 to the object side 101) and retracting (moving in the direction from the object side 101 to the image side 102) of the lens module 10 are positively correlated, that is, the greater the mutual pressing between the fourth member 14 and the third member 13 and/or the mutual pressing between the fourth member 14 and the first member 11, a higher dust-proof and water-proof level can be achieved, however, these pressing will cause the ejection initial state (ejecting from the fully retracted state) and the additional friction load will be generated near the fully retracted state (lateral pressure will be generated during the retracting process), and although the additional friction load can increase the dust-proof and water-proof effect (level), the greater the power of the driving member required to overcome the friction load to achieve the full ejection or the full retracting will also increase the volume of the driving member, and the life of the sealing material will be affected. If the fourth member 14 and the third member 13 are pressed against each other and/or the fourth member 14 and the first member 11 are pressed against each other, the lateral pressure is controlled to be in a small range, and the output power of the driving member is small, and the volume of the corresponding driving member is small, but the waterproof effect is reduced, and the low waterproof level cannot meet the current market demand. Therefore, a trade-off needs to be made between the dustproof and waterproof effect and the output power (or volume) of the driving motor.
In the lens module 10 of the present application, the second rotation speed of the driving member 151 is designed to be greater than the first rotation speed of the driving member 151 when the fourth member 14 is not subject to the lateral pressure, so that the characteristic that the driving member 151 has high torque at low rotation speed can be utilized, and the additional friction load caused by the mutual extrusion can be partially offset by the high torque generated at low rotation speed. Specifically, during the extension of the second member 12, in the ejection initial state, the driving member 151 drives the second member 12 to move toward the object side 101 at the lower first rotational speed (ejection/extension), and when the ejection initial state is ended, that is, the pressing between the fourth member 14 and the third member 13 is disappeared, and the pressing between the fourth member 14 and the first member 11 is also disappeared, the driving member 151 is restored to the higher second rotational speed; during retraction of the second part 12, the second part 12 is initially driven by the driving member 151 at a higher second rotational speed towards the image side 102 (retraction/retraction), and when approaching the fully retracted state, i.e. the compression between the fourth part 14 and the third part 13 and/or the compression between the fourth part 14 and the first part 11 is also generated, the driving member 151 is operated at a lower first rotational speed.
In an actual usage scenario, the working time of the pop-up lens module 10 is shorter (the time in the pop-up state is shorter), and the non-usage state of the lens module 10 (the time in the retracted state) is longer.
In the lens module 10 of the present application, since the additional friction load (lateral pressure) applied to the fourth component 14 is at least partially offset in the non-use state, the purpose of improving the waterproof and dustproof effects of the lens module 10 can be achieved without replacing the driving element 151 with a larger output power, and the problem that the volume of the driving element 151 is increased due to the increase of the output power of the driving element 151 is avoided, so that the volume of the lens module 10 is increased, and the production cost is increased. When the fourth component 14 is not subjected to additional lateral pressure, the rotation speed of the driving member 151 is controlled to be the second rotation speed, so that the sensitivity of the second component 12 to the movement of the first component 11 along the optical axis is ensured, and the user experience is improved. Therefore, the lens module 10 of the application can realize that the pop-up lens module 10 achieves a general dustproof and waterproof grade (such as life dustproof and waterproof, IP 54) in the pop-up state and achieves a dustproof and waterproof grade (such as IP 68) higher than the pop-up state under the premise of smaller volume (power) of the driving piece 151.
Referring to fig. 3 to 6, fig. 3 to 6 illustrate an embodiment of a lens module 10 according to the present application.
Specifically, referring to fig. 3 and 4, the third component 13 includes a first sub-portion 131 and a second sub-portion 133, and the first sub-portion 131 and the second sub-portion 133 may be connected in an inclined manner, so that the first sub-portion 131 and the second sub-portion 133 together form a groove 135, wherein a concave side of the groove 135 faces the object side 101 of the lens module 10. It will be appreciated that in one embodiment, the first sub-portion 131 is inclined towards the object side 101 of the lens module 10. In another embodiment, the second sub-portion 133 is inclined toward the object side 101 of the lens module 10. In yet another embodiment, the first sub-portion 131 and the second sub-portion 133 are both inclined towards the object side 101 of the lens module 10.
It should be noted that, the groove 135 formed by the first sub-portion 131 and the second sub-portion 133 can be used for accommodating impurities such as water or dust entering the first gap 119 from the outside, so as to avoid the problem that the imaging effect of the lens module 10 is deteriorated or even damaged due to the impurities entering the lens module 10 directly through the first gap 119.
In some embodiments, the second sub-portion 133 remains in interference with the second component 12 in the event that the driver 151 drives the second component 12 along the optical axis relative to the first component 11. Specifically, during the movement of the fifth member 15 to drive the second member 12 from the initial position (fully retracted state, shown in fig. 3) toward the object side 101 of the lens module 10, the second sub-portion 133 remains in contact with the second member 12; during the fifth part 15 drives the second part 12 from the fully ejected state (similar to that shown in fig. 8) of the lens module 10 to move towards the initial position, the second sub-portion 133 also keeps in contact with the second part 12, so that the second sub-portion 133 always seals the first gap 119 between the first part 11 and the second part 12, and the waterproof and dustproof effects of the lens module 10 are improved. In one example, the first sub-portion 131 is fixedly connected to the first member 11. In another example, the second sub-portion 133 is fixedly coupled to the second member 12. In yet another example, the first sub-portion 131 is fixedly connected with the first component 11 and the second sub-portion 133 is fixedly connected with the second component 12. Wherein, in the case that the first sub-portion 131 is fixedly connected with the first member 11 and the second sub-portion 133 is fixedly connected with the second member 12, the second sub-portion 133 can move together with the second member 12, and at this time, the third member 13 may have the same length as the stroke amount of the second member 12 moving relative to the first member 11; the third member 13 may be deformable within the amount of travel of the second member 12 relative to the first member 11 such that the third member 13 always seals the first gap 119 between the first member 11 and the second member 12. The fixing connection of the above embodiment may be, for example, adhesion, welding, or screws, which are not limited herein. In the lens module 10 of the present application, the second sub-portion 133 is kept in contact with the second component 12, so that the first gap 119 between the first component 11 and the second component 12 is sealed, and impurities such as water and dust are not easy to enter the accommodating cavity 115 from the first gap 119, so that the safety of elements (such as the image sensor 19) installed in the accommodating cavity 115 is ensured.
Referring to fig. 4, in some embodiments, in a direction from an object side 101 to an image side 102 of the lens module 10, an outer peripheral wall of the second component 12 includes a first section 121, a second section 123, and a third section 125 that are sequentially connected. The diameter of the first segment 121 is smaller than the diameter of the third segment 125, and the diameter of the second segment 123 gradually increases in the direction from the object side 101 to the image side 102 of the lens module 10. In some embodiments, the third component 13 may be made of a flexible material, such as rubber, silicone, etc., so that the third component 13 has better flexibility, so that the second sub-portion 133 of the third component 13 can elastically deform when abutting against the second component 12. Specifically, in the case where the driving member 151 drives the second member 12 to protrude along the optical axis with respect to the first member 11, the second sub-portion 133 of the third member 13 can move in the direction from the first segment 121 to the third segment 125 of the outer circumferential wall of the second member 12, so that the movement of the third member 13 can be buffered to some extent, and serious abrasion of the third member 13 due to excessive friction load is avoided, which affects the service life of the third member 13. In addition, since the diameter of the third section 125 is larger than that of the first section 121, the third section 13 receives greater lateral pressure from the side wall of the second section 12 when the second section 12 is in the extended condition, so that the waterproof and dustproof effects of the lens module 10 can be improved.
Referring again to fig. 4, in one embodiment, the fourth component 14 may include a first sub-component 141 and a second sub-component 143, and the first sub-component 141 and the second sub-component 143 may be connected by bending, so that the first sub-component 141 and the second sub-component 143 together form a recess 147, where the recess 147 faces the image side 102 of the lens module 10. It will be appreciated that in one embodiment, the first sub-member 141 is inclined towards the image side 102 of the lens module 10. In another embodiment, the second sub-member 143 is inclined toward the image side 102 of the lens module 10. In yet another embodiment, both the first sub-member 141 and the second sub-member 143 are inclined towards the image side 102 of the lens module 10.
In one embodiment, the second sub-portion 133 includes a first side (not shown) and a second side (not shown) opposite to each other, wherein the first side is the same as the object side 101 of the lens module 10, and the second side is the same as the image side 102 of the lens module 10. With the second part 12 in the retracted state, the second sub 143 abuts the second sub 133 of the third part 13, i.e. the second sub 143 abuts the first side of the second sub 133, and the second sub 143 is located in the recess 135 of the third part 13 such that the fourth part 14 cooperates with the third part 13 to seal the first gap 119 between the first part 11 and the second part 12. The recess 147 formed by the first sub-member 141 and the second sub-member 143 is used to avoid the second sub-portion 133, so as to avoid the second sub-portion 133 from being excessively engaged with the second sub-member 143, and the driving member 151 needs to consume a large output power to drive the second component 12 to move (particularly, to extend). In the present embodiment, the fourth member 14 is spaced from the first member 11, so that the driving member 151 cannot drive the lens module 10 to move along the optical axis direction due to excessive friction load between the fourth member 14 and the first member 11.
Referring to fig. 5, in another embodiment, the fourth component 14 may include a first sub-piece 141 and a second sub-piece 143, the second sub-piece 143 extending from the first sub-piece 141. The first sub-member 141 and the second sub-member 143 have a recess 147 therebetween, wherein the recess 147 faces the image side 102 of the lens module 10. Specifically, with the second component 12 in the retracted state, the second sub 143 interferes with the first component 11 to seal the first gap 119 between the first component 11 and the second component 12. In addition, the second sub-portion 133 of the third component 13 keeps contact with the second component 12, so that external water or dust is not easy to enter the lens module 10, and the waterproof and dustproof effects of the lens module 10 are improved.
Referring to fig. 6, in yet another embodiment, the fourth component 14 may include a first sub-piece 141, a second sub-piece 143, and a third sub-piece 145, the third sub-piece 145 extending from the second sub-piece 143. Specifically, the second sub-member 143 includes a first side and a second side opposite to each other, the first sub-member 141 is located on the first side of the second sub-member 143, the third sub-member 145 is located on the second side of the second sub-member 143, and the first side of the second sub-member 143 is located farther from the first component 11 (closer to the second component 12 as viewed in a transverse direction perpendicular to the optical axis) than the second side of the second sub-member 143. Specifically, with the second component 12 in the retracted state, the second sub 143 abuts the second sub 133 of the third component 13 and is located within the recess 135 of the third component 13, and the third sub 145 abuts the first component 11 to seal the first gap 119 between the first component 11 and the second component 12. That is, the second sub-component 143 and the second sub-portion 133, and the third sub-component 145 and the first component 11 all collide with each other, so that the fourth component 14 and the third component 13 together form a plurality of collision surfaces with the first component 11, and further the fourth component 14 receives greater lateral pressure, and impurities such as external water and dust can enter the lens module 10 after passing through the plurality of collision surfaces, thereby improving the waterproof and dustproof performance of the lens module 10.
It should be noted that, in some embodiments, the first sub-member 141 and the second sub-member 143 may be connected by bending, so that a recess 147 is formed between the first sub-member 141 and the second sub-member 143, and in the case that the second member 12 is in the retracted state, the recess 147 is used to avoid the second sub-portion 133 from being engaged with the fourth member 14 too tightly, so that the driving member 151 needs to consume a large output power to drive the second member 12 to move (especially, to extend).
In some embodiments, the number of the third sub-members 145 of the fourth member 14 may be plural, and the plurality of the third sub-members 145 are spaced apart in the optical axis direction. The third sub-components 145 may all collide with the first component 11, or the third sub-components 145 may simultaneously collide with the first component 11 and the third component 13, so that a plurality of collision surfaces are formed between the fourth component 14 and the third component 13 and between the fourth component 11, and impurities such as external water and dust can enter the lens module 10 after sequentially passing through the plurality of collision surfaces, thereby improving the waterproof and dustproof effects of the lens module 10.
In some embodiments, the fourth component 14 may also be made of a flexible material, such as rubber, silica gel, etc., so that the fourth component 14 may have better flexibility, so that elastic deformation can be generated when the fourth component 14 collides with the third component 13 or the first component 11, and damage to the lens device caused by rigid collision between the fourth component 14 and the third component 13 or the first component 11 is avoided.
Referring to fig. 7 to 11, fig. 7 to 11 illustrate another embodiment of the lens module 10 of the present application.
The third member 13 in the present embodiment is the same as the third member 13 in the embodiment shown in fig. 3, and the fourth member 14 in the present embodiment is the same as the fourth member 14 in the embodiment shown in fig. 3, and therefore, the structures of the third member 13 and the fourth member 14 in the present embodiment are not described in detail here. The seventh member 17 in this embodiment is substantially the same as the third member 13 in the embodiment shown in fig. 3, and the eighth member 18 in this embodiment is substantially the same as the fourth member 14 in the embodiment shown in fig. 3, so only the differences between the seventh member 17 and the third member 13, and between the eighth member 18 and the fourth member 14 will be described below.
Referring to fig. 7, in some embodiments, the lens module 10 may further include a sixth component 16, a seventh component 17, and an eighth component 18. Specifically, the sixth member 16 is formed with a housing chamber 165, and the first member 11, the second member 12, the third member 13, and the fourth member 14 are housed in the housing chamber 165. The fifth part 15 is also used to drive the first part 11 in relation to the sixth part 16 along the optical axis. The seventh part 17 is mounted between the first part 11 and the sixth part 16 and serves to seal a second gap 169 between the first part 11 and the sixth part 16. An eighth member 18 is mounted to the first member 11 and moves with the first member 11, the eighth member 18 for co-sealing the second gap 169 with the seventh member 17.
Wherein, referring to fig. 8, in certain embodiments, the seventh member 17 is held in abutment with the first member 11 to seal a second gap 169 between the first member 11 and the sixth member 16. The outer side wall of the first part 11 comprises a first section, a second section and a third section (not shown) which are connected in sequence. The diameter of the first section is smaller than that of the third section, and the diameter of the second section gradually increases in the direction from the object side 101 to the image side 102 of the lens module 10. In this way, the seventh part 17 can be better deformed flexibly in order to better deform the first part 11 when it moves along the optical axis relative to the sixth part 16, achieving a better sealing effect. Meanwhile, the diameter of the first section is smaller than that of the third section, and therefore, when the first member 11 starts to move from the fully retracted state in the direction of the object side 101 along the optical axis, the seventh member 17 receives less friction, so that the driving piece 151 can better drive the first member 11 to extend. Furthermore, after the first part 11 is fully extended, the seventh part 17 can be flexibly deformed to remain in interference with the outer peripheral wall of the first part 11, improving the sealing effect between the first part 11 and the sixth part 16. The first, second and third sections on the outer side wall of the first member 11 in this embodiment are substantially the same as the first, second and third sections 121, 123 and 125 on the outer side wall of the second member 12 shown in fig. 4.
Referring to fig. 9, in one embodiment, the eighth component 18 may include a first sub-component 181 and a second sub-component 183, and the first sub-component 181 and the second sub-component 183 may be connected by bending, so that the first sub-component 181 and the second sub-component 183 together form a recess, where the recess faces the image side 102 of the lens module 10. With the first component 11 in the retracted state, the second sub-element 183 abuts the second sub-portion 173 of the seventh component 17, i.e. the second sub-element 183 abuts the second sub-portion 173, such that the seventh component 17 cooperates with the eighth component 18 to seal the second gap 169 between the first and sixth components 11, 16. So that the external water or dust is not easy to enter the inside of the lens module 10, and the waterproof and dustproof effects of the lens module 10 are improved.
Referring to fig. 10, in another embodiment, the eighth member 18 may include a first sub-member 181 and a second sub-member 183, the second sub-member 183 extending from the first sub-member 181. The first sub-element 181 and the second sub-element 183 have a recess therebetween, wherein the recess faces the image side 102 of the lens module 10. Specifically, with the first component 11 in the retracted state, the second sub 183 abuts the sixth component 16 to seal the second gap 169 between the first component 11 and the sixth component 16. In addition, the second sub-portion 173 of the seventh member 17 is kept in contact with the first member 11, so that external water or dust is not easy to enter the inside of the lens module 10, and the waterproof and dustproof effects of the lens module 10 are improved.
Referring to fig. 11, in yet another embodiment, the eighth component 18 includes a first sub-component 181, a second sub-component 183, and a third sub-component 185, the third sub-component 185 extending from the second sub-component 183. Specifically, the second sub-element 183 includes a first side and a second side opposite to each other, the first sub-element 181 is located on the first side of the second sub-element 183, the third sub-element 185 is located on the second side of the second sub-element 183, and the first side of the second sub-element 183 is located farther from the sixth component 16 (closer to the first component 11 as viewed in a direction perpendicular to the optical axis) than the second side of the second sub-element 183. Specifically, with the first component 12 in the retracted state, the second sub 183 abuts the second sub 173 of the seventh component 17, and the third sub 185 abuts the sixth component 16 to seal the second gap 169 between the first component 11 and the sixth component 16. That is, the second sub-component 183 and the second sub-portion 173, and the third sub-component 185 and the sixth sub-component 16 are all in contact with each other, so that the eighth component 18 and the seventh component 17 together form a plurality of contact surfaces with the sixth component 16, and further the eighth component 18 receives a greater lateral pressure, and impurities such as external water and dust can enter the lens module 10 after passing through the plurality of contact surfaces, thereby further improving the waterproof and dustproof performance of the lens module 10.

Referring again to fig. 8, in some embodiments, the second component 12 includes a barrel assembly 127, a lens unit 128, and a second cover 129. The lens barrel assembly 127 is accommodated in the first cam cylinder 111 and is rotatably connected to the first cam cylinder 111. Specifically, the lens barrel assembly 127 may be a hollow structure such that the lens unit 128 may be received within the lens barrel assembly 127 and move together with the lens barrel assembly 127. Note that the hollow structure of the lens barrel assembly 127 means that the interior of the lens barrel assembly 127 is hollow. Wherein the lens barrel assembly 127 is rotatably connected with the first cam barrel 111.
In some embodiments, the second cover 129 is mounted on top of the barrel assembly 127, and the fourth member 14 is sandwiched between the top of the barrel assembly 127 and the second cover 129.

In one embodiment, the fourth member 14 and the second cover plate 129 may be provided separately, i.e., the fourth member 14 is sandwiched between the top of the barrel assembly 127 and the second cover plate 129, and cooperates with the third member 13 provided between the first member 11 and the second member 12 to seal the first gap 119 between the first member 11 and the second member 12. The fourth component 14 and the second cover plate 129 can be separately arranged, so that the size of the fourth component 14 can be conveniently adjusted to be suitable for different third components 13, and the waterproof and dustproof effects of the lens module 10 are ensured.
In another embodiment, the fourth member 14 and the second cover plate 129 may be integrally formed, i.e., the fourth member 14 and the second cover plate 129 are mounted together on top of the barrel assembly 127 and cooperate with the third member 13 to seal the first gap 119 between the first member 11 and the second member 12. The fourth component 14 and the second cover plate 129 are integrally formed, so that the assembly of the lens module 10 is facilitated, the processing technology of the fourth component 14 and the second cover plate 129 is simplified, and the production cost is reduced.
With continued reference to fig. 8 and 9, in some embodiments, the sixth member 16 includes a first shell 161 and a second shell 163. The first case 161 includes a top wall. The second housing 163 includes a top wall. Wherein the second housing 163 is combined with the first housing 161 to form a cavity 167, the driving member 151 is mounted on the first housing 161 and located outside the cavity 167, the seventh member 17 is sandwiched between the top wall 1611 of the first housing and the top wall 1631 of the second housing, and the eighth member 18 is fixed to the second cam cylinder 113.

The eighth member 18 is interposed between the first cover plate 117 and the outer peripheral wall of the second cam cylinder 113, and cooperates with the seventh member 17 to seal the second gap 169 between the first member 11 and the sixth member 16. Thereby improving the waterproof and dustproof effects of the lens module 10.
Referring to fig. 2 and 8, in some embodiments, the fifth component 15 may further include a transmission barrel 153 and a transmission assembly 155. The transmission cylinder 153 is accommodated in a cavity 167 formed by the first case 161 and the second case 163, and is rotatably connected to the second cam cylinder 113. The transmission assembly 155 is mounted to the first case 161, and the driving member 151 is connected to the transmission tube 153 through the transmission assembly 155 and is used for driving the transmission assembly 155 to move so as to drive the transmission tube 153 to rotate. Specifically, a gear bar matched with the transmission assembly 155 is disposed on the peripheral wall of the transmission barrel 153, and when the driving member 151 drives the transmission assembly 155 to move, the transmission assembly 155 is matched with the gear bar to drive the transmission barrel 153 to rotate. It should be noted that, in some embodiments, the transmission barrel 153 and the first cam barrel 111 may be connected by a pin, so that when the driving member 151 drives the transmission assembly 155 to move to rotate the transmission barrel 153, the transmission barrel 153 can drive the first cam barrel 111 to rotate, so that the first component 11 can move along the optical axis direction relative to the sixth component 16. In another embodiment, the first member 11 and the second member 12 may be connected by means of pins so that the second member 12 can be moved in the optical axis direction with respect to the first member 11.
In some embodiments, when the first component 11 moves relative to the sixth component 16 from the image side 102 to the object side 101, the second component 12 can also move relative to the first component 11 from the image side 102 to the object side 101, so that the lens module 10 achieves a two-stage pop-up effect, and the imaging effect of the lens module 10 is improved.
Further, in certain embodiments, the first component 11 may be provided as one or more. Wherein one or more first parts 11 are each arranged between the second part 12 and the sixth part 16.
Specifically, when the first member 11 is provided as one, the first member 11 is provided between the second member 12 and the sixth member 16, wherein the first member 11 is movable (extendable or retractable) with respect to the sixth member 16 in the direction of the optical axis of the lens module 10, and the second member 12 is movable (extendable or retractable) with respect to the first member 11 in the direction of the optical axis of the lens module 10, so that the lens module 10 can achieve two-stage ejection, thereby improving the imaging effect of the lens module 10. When the first member 11 is provided in plural, the plural first members 11 are each provided between the second member 12 and the sixth member 16. For example, the first parts 11 may be provided in two, wherein one first part 11 is provided close to the second part 12 and the other first part 11 is provided close to the sixth part 16 with a gap between the two first parts 11. The first part 11, which is adjacent to the sixth part 16, forms a receiving cavity, and both the first part 11 and the second part 12, which are adjacent to the second part 12, are located in the receiving cavity. Wherein, the first part 11 near the sixth part 16 can move (extend or retract) along the optical axis of the lens module 10 relative to the sixth part 16, the first part 11 near the second part 12 can move (extend or retract) along the optical axis of the lens module 10 relative to the first part 11 near the sixth part 16, and the second part 12 can move (extend or retract) along the optical axis of the lens module 10 relative to the first part 11 near the second part 12, so that the lens module 10 achieves the three-stage popup effect, and the imaging effect of the lens module 10 is improved. Similarly, when the first member 11 is provided in three, the lens module 10 can achieve the effect of four-stage ejection; when the first member 11 is provided in four, the lens module 10 can achieve the effect of five-stage ejection, and the like. That is, the number of the first components 11 can be determined according to the specific usage scenario of the lens module 10, so as to ensure the usage effect of the lens module 10 in different scenarios and improve the applicability of the lens module 10.
It should be noted that, in some embodiments, the gaps formed between the second members 12 may be sealed by providing the third member 13 and the fourth member 14, so as to avoid that when the lens module 10 performs multi-stage ejection, impurities such as external water or dust enter the lens module 10 to reduce or even damage the imaging effect of the lens module 10. In this embodiment, the third member 13 is the same as the third member 13 in the embodiment shown in fig. 3, and the fourth member 14 in the embodiment is the same as the fourth member 14 in the embodiment shown in fig. 3, so the structures of the third member 13 and the fourth member 14 in the embodiment are not described in detail here.
