Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a camera sealing member according to the present invention.
The camera sealing member 10 shown in fig. 1 may include a silicone sleeve 12 and a heat shrink tube 14, wherein the silicone sleeve 12 is used for being sleeved on the periphery of the camera to perform a sealing function, and the heat shrink tube 14 is used for being sleeved on a local area of the periphery of the silicone sleeve 12 to tightly sleeve the silicone sleeve 12 on the camera.
Specifically, heat shrink tube 14 may be made of ethylene-vinyl acetate copolymer, or may be made of other heat shrink materials. After the periphery of the camera is sleeved with the silica gel sleeve 12, the periphery of the silica gel sleeve 12 is sleeved with the heat shrinkage tube 14, and then the heat shrinkage tube 14 is heated to shrink the heat shrinkage tube, so that the silica gel sleeve 12 is tightly pressed and fixed on the camera, therefore, the silica gel sleeve 12 is not easy to fall off from the camera, smoothness of the installation process is ensured, the periphery of the camera can be firmly sleeved with the silica gel sleeve 12 and the heat shrinkage tube 14, namely the sealing element 10, the whole sealing element 10 is not easy to deform, and poor sealing effect caused by deformation, distortion, inexistence and the like of the sealing element 10 in the installation process is reduced, so that the sealing effect is improved, dust, water and the like are prevented from entering the camera to influence the image effect, and user experience is improved. At the same time, the occurrence of the need to reinstall the seal 10 due to deformation of the seal 10 during installation, or the need to repeatedly adjust the shape of the seal 10, is avoided.
The heat shrinkable tube 14 may be a ring-shaped tube or a tube having a certain length in the axial direction, and may be heated to shrink toward the axial center.

Fig. 2 shows a camera head assembly formed by fixing the camera head sealing member 10 to the camera head 20, and the camera head assembly is mounted on a device. The device on which the camera 20 is mounted is a mobile terminal 30, and it will be appreciated that in other embodiments, the device on which the camera 20 is mounted may be other electronic devices. The camera 20 of the present embodiment is mounted on the housing 32 of the mobile terminal 30, wherein a mounting hole 320 is provided on the housing 32, the sealing member 10 is sleeved on the periphery of the camera 20, the camera 20 and the sealing member 10 are mounted in the mounting hole 320, and a gap exists between the inner wall 322 of the mounting hole 320 and the outer wall 200 of the camera 20, and even if the gap is a tiny gap, dust, water and the like can still enter the camera 20 from the gap, so as to affect the image effect. The thickness of the silicone sleeve 12 of the sealing member 10 is greater than the width of the gap, and after the sealing member 10 is sleeved on the periphery of the camera 20, the silicone sleeve 12 can be compressed, so that the sealing member 10 and the camera 20 are not prevented from being installed in the installation hole 320 together, and the silicone sleeve 12 completely fills the gap because the thickness of the silicone sleeve 12 is greater than the width of the gap, so that dust, water and the like can be prevented from entering the camera 20.
Specifically, the cross-sectional shape of the silicone sleeve 12 may be kept uniform with the cross-sectional shape of the camera 20, and the cross-sectional shape of the heat shrinkage tube 14 may also be kept uniform with the cross-sectional shape of the camera 20. For example, if the cross-sectional shape of the camera is circular, the cross-sectional shape of the silicone sleeve may be circular, and the entire silicone sleeve may be circular.
For another example, the cross-sectional shape of the camera 20 in this embodiment is square, the cross-sectional shape of the silicone sleeve 12 is square ring, the overall silicone sleeve 12 may be square pipe, the cross-sectional shape of the heat shrinkage tube 14 is also square ring, and the overall heat shrinkage tube 14 may be square pipe.

When the accommodating groove 126 is provided at the end of the side wall 120 in the axial direction of the silicone sleeve 12, the circumference of the heat shrinkage tube 14 may be smaller than the circumference of the side wall 120 at the accommodating groove 126, or may be larger than the circumference of the side wall 120 at the accommodating groove 126. At this time, the whole heat shrinkage tube 14 may be sleeved in the accommodating groove 126, or one end of the heat shrinkage tube 14 may be sleeved on the outer periphery of the silica gel sleeve 12, and the other end of the heat shrinkage tube 14 may be sleeved on the outer periphery of the camera 20.
The accommodating groove 126 may be formed in various ways, for example, may be formed directly during injection molding of the silicone sleeve 12, or may be formed by digging, cutting, or the like on the surface of the silicone sleeve 12 after the silicone sleeve 12 is molded.
In some embodiments, the outer surface of the heat shrink tube 14 is flush with the outer surface of the side wall 120, or the outer surface of the heat shrink tube 14 is recessed inward relative to the outer surface of the side wall 120, so that the heat shrink tube 14 does not protrude from the outer surface of the silicone sleeve 12, and thus the close contact between the silicone sleeve 12 and the inner wall 322 of the mounting hole 320 is not affected, and the sealing effect of the sealing member 10 is ensured.
It should be noted that, in some embodiments, the side wall 120 of the silica gel sleeve 12 may not be provided with the accommodating groove 126, and the whole heat shrinkage tube 14 may be directly sleeved outside the side wall 120, or one end of the heat shrinkage tube 14 may be sleeved on the side wall 120, and the other end may be sleeved on the camera 20. In the case that the receiving groove 126 is not provided, after the heat shrinkage tube 14 is heated, the heat shrinkage tube 14 may be shrunk to compress the silicone sleeve 12 until the outer surface of the heat shrinkage tube 14 is flush or recessed with respect to the outer surface of the sidewall 120.
Specifically, the side wall 120 of the present embodiment is further provided with a rib 128 extending along the axial direction of the silica gel sleeve 12, and the rib 128 can play a guiding role in the process of installing the camera 20 and the sealing member 10 into the mounting hole 320, and can also strengthen the hardness of the side wall of the silica gel sleeve 12, reduce the deformation of the silica gel sleeve 12, further increase the connection tightness between the silica gel sleeve 12 and the inner wall 322 of the mounting hole 320, and further strengthen the dustproof and waterproof effects.
