The camera module 10 will be described in detail with reference to the drawings.

With continued reference to fig. 1, 5, 7, and 9, the camera module 10 includes a first component 11, a second component 12, and a third component 13.

Specifically, the first member 11 may be formed with a receiving cavity 111, the receiving cavity 111 may be used to receive a functional device (e.g., the second member 12, the image sensor 15, etc.), the first member 11 may provide protection for the functional device received in the receiving cavity 111, so that the functional device mounted in the receiving cavity 111 is not easily damaged, and the first member 11 may be provided with a connecting portion (e.g., a connecting hole, a buckle, etc.) connected to an external structure, so as to mount the first member 11 on the external structure through the connecting portion, and further mount the camera module 10 on the external structure (e.g., a mobile phone shell, a tablet shell, a substrate assembly, etc.).

In some embodiments, the camera module 10 shown in fig. 1, 5, 7 and 9 may further include a driving member, and a driving structure for driving the second member 12 to move relative to the first member 11.

Specifically, the fourth component 14 can drive the second component 12 to move relative to the first component 11 toward the object side 101 and the image side 102 of the camera module 10. For example, when shooting with the camera module 10 is required, the fourth component 14 may drive the second component 12 to move from the initial position toward the object side 101 of the camera module 10; when the camera module 10 is not needed, the fourth component 14 can drive the second component 12 to move toward the image side 102 of the camera module 10 to return to the initial position of the camera module 10. The driving structure in the camera module 10 of the embodiment shown in fig. 1 and 5 is the same, and is not shown in fig. 1 and 5.

In one example, the moving member 142 may be a self-driving member that can autonomously move on the guide rail 141. In another example, the moving member 142 may be a driven member, the driven member is connected to a driving element, and the moving member 142 may move on the guide rail 141 under the driving of the driven element (e.g., a motor). In another example, the moving element 142 may be deformed after being powered on to drive the second component 12 to move along the object side relative to the first component 11, and the moving element 142 may be restored after being powered off to drive the second component 12 to move along the image side relative to the first component 11.

Referring to fig. 1 to 4, fig. 1 to 4 show an embodiment of a camera module 10 according to the present application.

Specifically, the first member 11 includes a first sub-member 112, and the first sub-member 112 may be a hollow structure, such that the first sub-member 112 may be formed with a first sub-cavity 1121, and the first sub-cavity 1121 may at least partially receive the second member 12. It will be appreciated that the second member 12 may be partially received within the first sub-cavity 1121, or the second member 12 may be fully received within the first sub-cavity 1121. It should be noted that, the first sub-member 112 is a hollow structure, which means that the inside of the first sub-member 112 is hollow, and one side or both sides of the first sub-member 112 are provided with openings. The first sub-assembly 112 can be coupled to an external structure (a circuit board), and the camera module 10 can be mounted on the external structure. For example, the first sub-assembly 112 may be fixedly mounted to the external structure by fasteners such as screws.

Referring to fig. 1, the first sub-assembly 112 includes a first side and a second side opposite to each other, the first side is the same side as the object side 101 of the camera module 10, and the second side is the same side as the image side 102 of the camera module 10. The first component 11 may further include a second sub-component 113, and the second sub-component 113 may be of a hollow construction (explained above), the second sub-component 113 being mounted to a first side of the first sub-component 112. In one example, the second sub-member 113 can be fixedly mounted on the first sub-member 112 by a fastener such as a screw, and the second sub-member 113 can also be mounted on the first sub-member 112 by gluing or the like.

Specifically, when the second sub-member 113 is mounted on the first sub-member 112, the second sub-member 113 and the first sub-member 112 may form a second sub-cavity 1132 together, and the second sub-cavity 1132 and the first sub-cavity 1121 may form the receiving cavity 111 together. In one example, second subchamber 1132 may be adapted to receive at least a portion of third member 13 to fixedly mount third member 13 to first member 11, as shown in fig. 1. Of course, the second sub-cavity 1132 may also be used for accommodating other components, which are not listed here.

In some embodiments, the camera module 10 shown in fig. 1, 5, 7, and 9 can further include a third sub-assembly for mounting to the first sub-assembly 112. For example, referring to fig. 7 and 9, in some embodiments, the second side of the first member 11 is an open side. The first component 11 may further include a third sub-component 114, the third sub-component 114 may be mounted on a second side of the first sub-component 112, and the third sub-component 114 may have an image sensor 15 and the like mounted thereon. The third sub-component 114 can be fixedly mounted on the second side of the first sub-component 112 by means of bonding, welding, screwing, and the like, and furthermore, a sealing strip and the like can be further provided between the third sub-component 114 and the first sub-component 112 to seal the gap between the third sub-component 114 and the first sub-component 112, so that impurities such as water and dust are not easy to enter the receiving cavity 111 from the gap between the first sub-component 112 and the third sub-component 114, and further, the safety of the component (such as the image sensor 15) mounted in the receiving cavity 111 is ensured. The third sub-component of the camera module 10 according to the embodiment shown in fig. 1 and 5 is the same as the first sub-component, and is not shown in fig. 1 and 5.

Referring to fig. 1, 5, 7 and 9, the second member 12 can be installed in the receiving cavity 111, and the second member 12 can move in the receiving cavity 111 and then move relative to the first member 11. For example, the second member 12 may be moved toward the object side 101 with respect to the first member 11, and the second member 12 may be moved toward the image side 102 with respect to the first member 11. The second sub-member 113 may be formed with an avoiding hole 1133, and when the second component 12 is located at the initial position, the second component 12 may be completely accommodated in the accommodating cavity 111. When the camera module 10 needs to be used, the fourth component 14 can drive the second component 12 to move, so that the second component 12 can protrude out of the accommodating cavity 111 from the avoiding hole 1133. This can save the volume of the camera module 10, and the camera module 10 can be mounted on the terminal 100 (shown in fig. 11) to reduce the volume of the terminal 100.

Referring to fig. 1, 5, 7 and 9, the second component 12 includes a lens barrel 121, a frame 122 and a lens 123, the lens barrel 121 can be accommodated in the accommodating cavity 111, and the lens barrel 121 can move relative to the first component 11. Specifically, the lens barrel 121 may be connected to the fourth component 14, such that the lens barrel 121 may be driven by the fourth component 14 to move relative to the first component 11, thereby changing the installation position of the lens barrel 121 in the receiving cavity 111. The lens barrel 121 can be provided with an accommodating cavity 1211, and the accommodating cavity 1211 can be used for accommodating the lens frame 122. The frame 122 can be fixedly mounted in the cavity 1211, the frame 122 can have a mounting cavity 1221, and the mounting cavity 1221 can be used to receive the lens 123. The lens 123 can be fixedly mounted in the mounting cavity 1221 of the frame 122 such that the lens 123 is more stable and the lens 123 is less likely to separate from the frame 122 when the second member 12 is moved. For example, the inner surface of the frame 122 can be formed with a plurality of mounting grooves into which the lenses 123 can be mounted and snapped so that the lenses 123 do not fall off the frame 122. When the lens barrel 121 moves relative to the first member 11, the frame 122 and the lens 123 can move together with the lens barrel 121. The number of the lens 123 may be plural, and the lens 123 may include a concave lens, a convex lens, a half-reflecting half-transmitting mirror, and the like, which are not listed here.

Referring to fig. 1, in some embodiments, the camera module 10 may further include a sealing ring 16, the sealing ring 16 may be mounted on a side of the second member 12 facing the image side 102, and the sealing ring 16 may be located in the receiving cavity 111. When the second member 12 moves to the first position, the sealing ring 16 may contact with an inner surface of the top wall of the first sub-cavity 1121, so that the sealing ring 16 may seal a gap between the second member 12 and the top wall of the first sub-cavity 1121, and when impurities such as water, dust, and the like enter the first sub-cavity 1121 through the third member 13, the sealing ring 16 may prevent the impurities such as water, dust, and the like from contacting sensitive elements such as an image sensor and the like located in the first sub-cavity 1121. Further, a protrusion 161 may be further disposed at an end of the sealing ring 16 away from the second component 12, and water needs to flow over the protrusion 161 to enter the bottom of the first sub-cavity 1121, so that the sealing ring 16 may have a better waterproof effect.

Referring to fig. 1 and 2, the third member 13 is installed between the first member 11 and the second member 12, and the third member 13 may seal a gap between the first member 11 and the second member 12. Through setting up third part 13, impurity such as water, dust can be avoided passing through the clearance between first part 11 and second part 12 and get into and accept chamber 111 for elements such as image sensor that install in accepting chamber 111 are difficult for receiving the influence of impurity such as water, dust. In one example, the third component 13 may be mounted within the second sub-cavity 1132 formed by the first sub-component 112 and the second sub-component 113, with the third component 13 being more stable by the constraint of the first sub-component 112 and the second sub-component 113.

Specifically, the third component 13 includes a contact portion 131 contacting the second component 12, and the contact portion 131 may contact an outer surface of the second component 12, so that there is no gap or a small gap between the third component 13 and the second component 12, and the third component 13 may serve to better seal the gap between the second component 12 and the first component 11. When the contact portion 131 moves along the first direction a and the second direction B, the contact portion 131 is always located in the first sub-cavity 1121, so that the contact portion 131 can achieve a better sealing effect.

Further, with reference to fig. 1 and fig. 2, the third component 13 further includes a main body 132, and the main body 132 can be fixedly mounted on the first component 11, so that the third component 13 can be fixedly mounted on the first component 11. For example, the main body portion 132 may be engaged with the first member 11 such that the main body portion 132 is fixedly attached to the first member 11. More specifically, the main body portion 132 may be mounted in the first sub-cavity 1121, and the first sub-component 112 and the second sub-component 113 are respectively clamped on both sides of the main body portion 132, so that the main body portion 132 may be more securely mounted in the first component 11.

In the embodiment shown in fig. 1 and 2, the main body 132 is provided with a groove 1321, the second sub-component 113 is provided with a protrusion 1134, and the protrusion 1134 can cooperate with the groove 1121 to limit the installation position of the main body 132. Of course, in other embodiments, the main body 132 may have a protrusion and the second sub-member 113 may have a groove. Alternatively, the main body 132 may be provided with a protrusion and the first sub-member 112 may be provided with a groove. Alternatively, the main body 132 is provided with a recess, and the first sub-member 112 is provided with a projection.

Referring to fig. 1 and fig. 2, the contact portion 131 may be connected to the main body portion 132 at a pivot, and the contact portion 131 may move along the first direction a and the second direction B relative to the pivot. Specifically, when the second member 12 moves toward the object side 101 with respect to the first member 11, the contact portion 131 may move in the first direction a with respect to the fulcrum, and when the second member 12 moves toward the image side 102 with respect to the first member 11, the contact portion 131 may move in the second direction B with respect to the fulcrum, and the first direction a is opposite to the second direction B. The contact part 131 can move along with the second component 12, so that the friction force between the third component 13 and the second component 12 is reduced, and the phenomenon that the sealing effect of the third component 13 is influenced due to abrasion caused by friction between the third component 13 and the second component 12 caused by movement of the second component 12 is avoided. In one example, the first direction a is counterclockwise and the second direction B is clockwise.

The third component 13 may be made of a flexible material, such as rubber, silicon gel, etc., so that the third component 13 may have good flexibility to facilitate the elastic deformation of the contact portion 131 relative to the main body portion 132. Further, the size of the contact portion 131 may be smaller than that of the body portion 132, or the size of a portion where the contact portion 131 is connected to the body portion 132 may be smaller, so that the contact portion 131 may move in the first direction a and the second direction B with respect to the fulcrum.

Further, when the contact portion 131 moves along the first direction a and the second direction B, the contact portion 131 can stretch or contract, so that the contact portion 131 is always in contact with the second component 12 during the movement of the second component 12, and impurities such as water and dust are effectively prevented from entering the receiving cavity 111 during the movement of the second component 12. For example, during the movement of the contact portion 131 from the first position to the second position, the contact portion 131 will move along the first direction a, and the size of the contact portion 131 gradually decreases and then gradually increases. More specifically, a portion of the contact portion 131 near the fulcrum (e.g., a third, a half, a quarter, etc. of the contact portion 131) is corrugated, so that a deformation space for the contact portion 131 to elongate or shorten is larger.

With continued reference to fig. 1 and 2, in one embodiment, the contact portion 131 includes a first end 1311 and a second end 1312 opposite to each other, the first end 1311 is fixedly connected to the body portion 132, and the second end 1312 is capable of contacting the second component 12 to seal a gap between the second component 12 and the first component 11. Second end 1312 is movable about first end 1311, and as second end 1312 is in contact with second part 12, second end 1312 will follow second part 12 as second part 12 moves relative to first part 11. For example, when second member 12 is moved toward image side 102 relative to first member 11, second end 1312 will move in second direction B about first end 1311, as shown in fig. 4; when the second part 12 moves towards the object side 101 relative to the first part 11, the second end 1312 will move around the first end 1311 in the first direction a, as shown in fig. 3; thus, the second end 1312 is always in contact with the second member 12, and the waterproof and dustproof effects of the camera module 10 are improved.

Further, referring to fig. 1 and fig. 2, the contact portion 131 further includes a limiting end 1313, and in the process that the second end 1312 rotates around the first end 1311, the limiting end 1313 can abut against the main body 132 or the first component 11, so that the limiting end 1313 can limit the rotation stroke of the second end 1312, and prevent the second end 1312 from being separated from the second component 12 due to an excessively large rotation range of the second end 1312, thereby ensuring the waterproof and dustproof performance of the camera module 10 when the second component 12 moves.

In one embodiment, referring to fig. 2, the number of the position-limiting ends 1313 is two, namely, the first position-limiting end 1314 and the second position-limiting end 1315, and the contact portion 131 includes a first side and a second side opposite to each other, and the first side is farther away from the first sub-assembly 112 (closer to the object side 101) than the second side. The first position-limiting end 1314 is located at the first side of the contact portion 131, the second position-limiting end 1315 is located at the second side of the contact portion 131, and during the movement of the second end 1312 along the first direction a, the first position-limiting end 1314 can abut against the main body portion 132, and the second end 1312 cannot move continuously along the first direction a; in the process that the second end 1312 moves along the second direction B, the second position-limiting end 1315 can abut against the main body 132, and the second end 1312 cannot move continuously along the second direction B, so that the first position-limiting end 1314 and the second position-limiting end 1315 respectively limit the stroke of the second end 1312 in the first direction a and the second direction B, and the second end 1312 is effectively prevented from being separated from the second member 12 due to an excessively large rotation range of the second end 1312 in the first direction a and the second direction B.

In the embodiment shown in fig. 1, the shape of the contact portion 131 is a cross shape, but the shape of the contact portion 131 is not limited to the cross shape, and may be other shapes, which are not listed here.

In addition, the number of the contact portions 131 may be plural, for example, the number of the contact portions 131 may be two, three, four, five, six, seven, eight, or more. Every contact site 131 includes the contact surface with the contact of second part 12, and the contact surface looks interval of a plurality of contact sites 131 sets up at a plurality of contact surface intervals, and impurity such as water, dust need pass through a plurality of contact surfaces in proper order just can get into and receive the chamber 111 in, have promoted camera module 10's waterproof dustproof performance.

Referring to fig. 1, in some embodiments, the lens barrel 121 may be formed with a light inlet 1212, and the light may enter the lens 123 through the light inlet 1212. However, impurities such as moisture and dust in the outside air are also likely to enter the lens 123 through the light inlet 1212, so that the lens 123 is contaminated, and the function of the lens 123 is affected. Therefore, the camera module 10 may further include a light-transmitting protective cover 17, and the protective cover 17 may be mounted on the lens barrel 121 and seal the light inlet 1212, so that impurities such as moisture and dust in the outside air are not easily introduced into the lens 123. The protective cover 17 may be made of transparent plastic or transparent glass.

Referring to fig. 5 and 6, fig. 5 and 6 show another embodiment of the camera module 10 of the present application.

The first component 11 in this embodiment is the same as or approximately the same as the first component 11 in the embodiment shown in fig. 1 to 4, the second component 12 in this embodiment is the same as or approximately the same as the second component 12 in the embodiment shown in fig. 1 to 4, and the main body 132 of the third component 13 in this embodiment is the same as or approximately the same as the main body 132 of the third component 13 in the embodiment shown in fig. 1 to 4, so that detailed description is not provided herein.

Referring to fig. 5 and 6, the contact portion 131 includes a first sub-contact portion 1316 and a second sub-contact portion 1317, the fulcrum includes a first fulcrum and a second fulcrum, the first sub-contact portion 1316 is connected to the main body portion 132 at the first fulcrum, the first sub-contact portion 1316 extends from the first fulcrum along the third direction, and the first sub-contact portion 1316 contacts the second component 12, so that the first sub-contact portion 1316 may seal a gap between the first component 11 and the second component 12. The first sub-contact portion 1316 can be flexibly deformed, so that the first sub-contact portion 1316 can move relative to the first fulcrum, and therefore, when the second component 12 moves relative to the first component 11, the first sub-contact portion 1316 can be flexibly deformed to follow the second component 12, so that abrasion of the first sub-contact portion 1316 caused by friction between the second component 12 and the first sub-contact portion 1316 is reduced, and the sealing effect of the first sub-contact portion 1316 is improved.

In the embodiment shown in fig. 6, the cross-sectional area of the first sub-contact portion 1316 is gradually smaller along the third direction, so that the first sub-contact portion 1316 can be flexibly deformed better to follow the movement of the second component 12, and a better sealing effect can be achieved. At the same time, the friction between the first sub-contact portion 1316 and the second component 12 will be less, reducing the wear of the first sub-contact portion 1316. When the first sub-contact portion 1316 moves in the first direction a or the second direction B, the position of the first sub-contact portion 1316 relative to the first component 11 changes and the first sub-contact portion 1316 is always located in the receiving cavity 111.

Referring to fig. 5 and 6, the second sub-contact portion 1317 and the main body portion 132 are connected to the second pivot, and the second sub-contact portion 1317 extends from the second pivot along the fourth direction, so that the second sub-contact portion 1317 can contact with the second component 12, and the third component 13 can further seal the gap between the first component 11 and the second component 12 on the basis of sealing the first sub-contact portion 1316, thereby improving the waterproof and dustproof performance of the camera module 10. The contact surface or point of the second sub-contact 1317 with the second member 12 is spaced apart from the contact surface or point of the first sub-contact 1316 with the second member 12 so that the third member 13 may have a better sealing effect.

Further, the second sub-contact 1317 can be flexibly deformed, so that the second sub-contact 1317 can move relative to the second fulcrum, and therefore, when the second component 12 moves relative to the first component 11, the second sub-contact 1317 can be flexibly deformed to follow the second component 12, so that abrasion of the second sub-contact 1317 due to friction between the second component 12 and the second sub-contact 1317 is reduced, and the sealing effect of the second sub-contact 1317 is improved.

In the embodiment shown in fig. 6, the cross-sectional area of the second sub-contact 1317 is gradually smaller along the fourth direction, so that the second sub-contact 1317 can be flexibly deformed better to follow the movement of the second component 12, and a better sealing effect is achieved. At the same time, the friction between the second sub-contact 1317 and the second part 12 will be smaller, reducing the wear of the second sub-contact 1317. When the second sub-contact 1317 moves in the first direction a or the second direction B, the position of the second sub-contact 1317 relative to the first component 11 changes and the second sub-contact 1317 is always located in the receiving cavity 111.

Further, referring to fig. 5 and 6, the third direction and the fourth direction are different, so that the contact portion 131 can seal the gap between the first component 11 and the second component 12 from two different directions, and the sealing performance of the third component 13 is improved. Specifically, the included angle between the third direction and the fourth direction is between 0 ° and 180 °, the third direction is from the first fulcrum to be away from the first sub-component 112, and the fourth direction is from the second fulcrum to be close to the first sub-component 112, so that, when there is a dimensional error between the second component 12 and the first component 11, the first sub-contact portion 1316 can be flexibly deformed in the first direction a according to the dimensional error between the second component 12 and the first component 11, so that the normal force between the first sub-contact portion 1316 and the second component 12 is small, and the second component 12 can move relative to the first component 11 more smoothly. The second sub-contact 1317 may be flexibly deformed in the second direction B according to a dimensional error of the second member 12 and the first member 11, so that a normal force between the second sub-contact 1317 and the second member 12 is small, and the second member 12 may move more smoothly with respect to the first member 11. Accordingly, the first sub-contact portion 1316 and the second sub-contact portion 1317 can preferably suppress excessive increase and decrease of the normal force of the third member 13, so that the waterproof performance of the third member 13 is relatively stable.

Further, referring to fig. 6, the first sub-contact portion 1316 and the second sub-contact portion 1317 are symmetrical with respect to the main body portion 132, that is, the third direction and the fourth direction are symmetrical with respect to the horizontal direction, whereby the first sub-contact portion 1316 and the second sub-contact portion 1317 can better seal the gap between the first member 11 and the second member 12. And, the normal force of the first sub-contact 1316 and the second sub-contact 1317 is the same or approximately the same, when there is a dimensional error of the second member 12 and the first member 11, the first sub-contact 1316 and the second sub-contact 1317 may be flexibly deformed according to the dimensional error of the second member 12 and the first member 11, and the degree of the flexible deformation of the first sub-contact 1316 and the second sub-contact 1317 is the same, so that the first sub-contact 1316 and the second sub-contact 1317 may be more stably contacted with the second member 12.

The extending directions of the first sub-contact portion 1316 and the second sub-contact portion 1317 are both straight lines, and the included angle formed between the two portions may be 30 °, 50 °, 60 °, 80 °, 90 °, 100 °, 120 °, 135 °, 150 °, and so on, which are not listed here. In other embodiments, the first sub-contact portion 1316 and the second sub-contact portion 1317 may extend in both directions, and the included angle between the tangents of the two arcs may be 30 °, 50 °, 60 °, 80 °, 90 °, 100 °, 120 °, 135 °, 150 °, etc., which are also not enumerated herein.

Of course, the contact portion 131 may further include a third sub-contact portion, a fourth sub-contact portion, a fifth sub-contact portion, or more sub-contact portions, which are not described in detail herein, and are not limited, the plurality of sub-contact portions may be disposed at intervals, and the arrangement of the plurality of sub-contact portions can further improve the waterproof effect.

Referring to fig. 7 and 8, fig. 7 and 8 show a camera module 10 according to still another embodiment of the present disclosure.

Referring to fig. 7 and 8, the third component 13 includes a first sealing member 133, and the first sealing member 133 is mounted on the second component 12 and can move along with the second component 12. When the second component 12 is moved to the first position, the first seal 133 can contact the first sub-component 112 (shown in fig. 7) to seal the gap between the second component 12 and the first sub-component 112, so that impurities such as water, dust, etc. are less likely to enter into the receiving cavity 111 when the second component 12 is in the first position. The portion of the first sealing member 133 that can contact the first sub-member 112 can be regarded as the contact portion 131 of the third member 13, and when the second member 12 moves, the contact portion 131 can move along with the second member 12 so that the position of the contact portion 131 relative to the first member 11 changes and the contact portion 131 is always located in the accommodating cavity 111, so that water and dust are not easily introduced into the accommodating cavity 111. The first position may be a position where the second component 12 is located when the camera module 10 needs to acquire an image.

Specifically, the first sealing member 133 may have a ring shape, such as an O shape, so that the first sealing member 133 may be sleeved on the lens barrel 121, and thus the first sealing member 133 may move along with the lens barrel 121 when the lens barrel 121 moves. Wherein the first sealing element 133 may be made of a flexible material, such as rubber, silicon, etc., and when the first sealing element 133 contacts the first sub-assembly 112, the first sealing element 133 may partially extend into the gap between the second component 12 and the first sub-assembly 112, so that the first sealing element 133 may more tightly seal the gap between the second component 12 and the first sub-assembly 112. In one example, the first sealing member 133 is made of rubber, so that the first sealing member 133 is not easily corroded by water, and can have a long service life and a good sealing effect.

The first sealing element 133 may be directly sleeved on the lens barrel 121 through interference fit, or the first sealing element 133 may be fixed on the lens barrel 121 through adhesion, so that the first sealing element 133 is not easily separated from the lens barrel 121. The first sealing member 133 may be circular, square, polygonal, etc., and the shape of the first sealing member 133 may be correspondingly set according to the shape of the second member 12.

Further, with continuing reference to fig. 7 and 8, the third component 13 may further include a second sealing element 134, the second sealing element 134 is mounted on the second sub-component 113 of the first component 11, when the second component 12 is in the second position, the second sealing element 134 may contact the second component 12, so that the second sealing element 134 may seal a gap between the second component 12 and the second sub-component 113, and further, when the second component 12 is in the second position, water, dust, and the like are not easily affected on the image sensor 15. The second position may be a position in which the camera module 10 is not in operation. Accordingly, the first seal 133 and the second seal 134 make it difficult for water, dust, and the like to damage the elements such as the image sensor 15 and the like when the second member 12 is at the first position and the second position.

The second sealing element 134 may be made of a flexible material, such as rubber, so that the second component 12 and the second sealing element 134 can be attached more closely, and meanwhile, the second sealing element 134 is not easily corroded by liquid, such as water, so as to improve the waterproof performance of the second sealing element 134.

Of course, in other embodiments, the second seal 134 may be disposed on the second component 12, and the second seal 134 may contact the second sub-component 113 when the second component 12 is in the second position, which will not be described in detail herein.

Referring to fig. 7 and 8, in some embodiments, the camera module 10 may further include a blocking member 18, the second sub-cavity 1132 may be configured to receive the blocking member 18, and the blocking member 18 may reduce a gap between the second sub-component 113 and the second component 12, so that impurities such as water and dust outside the camera module 10 are not easy to enter the receiving cavity 111, and the waterproof and dustproof performance of the camera module 10 is improved. Further, barrier 18 may be in contact with second component 12. The blocking member 18 may be made of silicon rubber, etc., and the size of the blocking member 18 is not limited herein.
