Please refer to FIG. 1 , which is a schematic structural diagram of an embodiment of a camera seal provided by the present invention.

The camera seal 10 shown in Figure 1 may include a silicone sleeve 12 and a heat shrink tube 14. The silicone sleeve 12 is used to cover the outer periphery of the camera for sealing, and the heat shrink tube 14 is used to cover the outer periphery of the camera. A local area of the outer periphery of the silicone sleeve 12 is used to tightly set the silicone sleeve 12 on the camera head.

Specifically, the heat shrinkable tube 14 may be made of ethylene-vinyl acetate copolymer, or may also be made of other heat shrinkable materials. After the silicone sleeve 12 is set on the periphery of the camera head, the heat shrink tube 14 is set on the outer circumference of the silicone sleeve 12, and then the heat shrink tube 14 is heated to shrink, thereby pressing and fixing the silicone sleeve 12 on the camera head. Therefore, The silicone sleeve 12 is not easy to fall off from the camera, thereby ensuring a smooth installation process. Moreover, since the silicone sleeve 12 and the heat shrink tube 14, that is, the seal 10, can be firmly set on the periphery of the camera, the seal 10 is not integral as a whole. It is no longer easy to deform, so it also reduces the occurrence of poor sealing effect due to the deformation and twisting of the seal 10 during the installation process, thereby improving the sealing effect and avoiding dust, water, etc. from entering the camera and affecting the camera. Image effects improve user experience. At the same time, it is also avoided that the seal 10 needs to be reinstalled due to deformation during the installation process, or the shape of the seal 10 needs to be repeatedly adjusted.

Among them, the heat shrinkable tube 14 can be in the shape of a circle, or it can be a tube with a certain length in the axial direction, which can realize the function of heating and shrinking toward the axis.

As shown in Figures 2 and 3, Figure 2 is a schematic cross-sectional structural diagram of the area where the camera is located in an embodiment of a mobile terminal provided by the present invention. Figure 3 is an exploded view of the area where the camera is located in an embodiment of a mobile terminal provided by the present invention. Schematic. Figure 2 shows a camera assembly formed by fixing the camera seal 10 on the camera 20, and the camera assembly is installed on a device. The device on which the camera 20 is installed is the mobile terminal 30. It is understandable that in some other embodiments, the device on which the camera 20 is installed can also be other electronic devices. The camera 20 of this embodiment is installed on the casing 32 of the mobile terminal 30. The casing 32 is provided with a mounting hole 320, and the seal 10 is set around the periphery of the camera 20. The camera 20 and the seal 10 are installed In the mounting hole 320, there is a gap between the inner wall 322 of the mounting hole 320 and the outer wall 200 of the camera 20. Even if the gap is a tiny gap, dust, water, etc. can still enter the camera 20 through the gap and affect the image. Effect. The thickness of the silicone sleeve 12 of the seal 10 is greater than the width of the gap. After the seal 10 is placed around the periphery of the camera 20, since the silicone sleeve 12 can be compressed, it does not prevent the seal 10 and the camera 20 from being installed into the installation hole together. 320, and because the thickness of the silicone sleeve 12 is greater than the width of the gap, the silicone sleeve 12 completely fills the gap, thereby preventing dust, water, etc. from entering the camera 20.

Specifically, the cross-sectional shape of the silicone sleeve 12 can be consistent with the cross-sectional shape of the camera 20 , and the cross-sectional shape of the heat shrink tube 14 can also be consistent 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 can be in the shape of a ring, and the overall silicone sleeve can be in the shape of a circular tube.

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 a square ring, the silicone sleeve 12 as a whole can be in the shape of a square tube, and the cross-section shape of the heat shrink tube 14 is also in the shape of a square ring. shape, the heat shrinkable tube 14 can be in the shape of a square tube as a whole.

The square tubular silicone sleeve 12 of this embodiment includes a side wall 120 and a top wall 122. The top wall 122 is formed by extending inwardly from the top circumference of the side wall 120. The top wall 122 can cover the edge area of the top of the camera 20. Moreover, the top wall 122 of this embodiment has a larger area at the four corners of the silicone sleeve 12 .

In this embodiment, the top wall 122 is also provided with a ridge 124. When the camera 20 is installed on the mobile terminal 30, the middle frame 34 and other components of the mobile terminal 30 will press the camera 20 toward the housing 32, so that The protruding ribs 124 press the housing 32 of the mobile terminal 30 tightly to act as a seal. It can be understood that in some embodiments, the camera 20 can be sealed only by the convex rib 124 of the top wall 123, and the side wall 120 does not have a sealing effect. Alternatively, the convex rib 124 and the side wall 120 can also be used for sealing together. effect.

The outer surface of the side wall 120 of the silicone sleeve 12 can be provided with a receiving groove 126 , wherein the heat shrink tube 14 is disposed in the receiving groove 126 , and the receiving groove 126 can be provided along the side wall 120 of the silicone sleeve 12 The middle or end of the axis.

Specifically, when the accommodating groove 126 is disposed in the middle of the side wall 120 , the entire heat shrinkable tube 14 is completely disposed in the accommodating groove 126 . At this time, the circumference of the heat shrink tube 14 can be set to be larger than the circumference of the area of the side wall 120 outside the accommodating groove 126 , so that the heat shrink tube 14 can be inserted into the position of the accommodating groove 126 . It is understandable that the circumference of the heat shrinkable tube 14 can also be set to be smaller than the circumference of the area of the side wall 120 outside the accommodating groove 126, and at the same time larger than the outer circumference of the camera 20. Since the silicone sleeve 12 can deform, Therefore, the silicone sleeve 12 can be adjusted to deform, and then the heat shrink tube 14 can be inserted into the accommodation groove 126 of the silicone sleeve 12. Before heating the heat shrink tube 14, the side wall 120 outside the accommodation groove 126 can be In this area, the heat shrink tube 14 can be stuck in the receiving groove 126 to facilitate the positioning of the heat shrink tube 14 .

When the accommodating groove 126 is provided at the end of the side wall 120 along the axial direction of the silicone sleeve 12, the circumference of the heat shrink tube 14 can be set to be smaller than the circumference of the accommodating groove 126 of the side wall 120, or it can be is greater than the circumference of the receiving groove 126 of the side wall 120 . At this time, the entire heat shrink tube 14 can be sleeved in the accommodating groove 126 , or one end of the heat shrink tube 14 can be sleeved on the outer periphery of the silicone sleeve 12 , and the other end of the heat shrink pipe 14 can be sleeved on the outer periphery of the silicone sleeve 12 . The periphery of the camera 20 .

Among them, the accommodating groove 126 can be formed in various ways. For example, it can be formed directly when the silicone sleeve 12 is injection molded, or it can be formed by digging, Formed in such a way.

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 is not It will protrude from the outer surface of the silicone sleeve 12, so it will not affect the close contact between the silicone sleeve 12 and the inner wall 322 of the mounting hole 320, ensuring the sealing effect of the seal 10.

It is worth mentioning that in some embodiments, the receiving groove 126 may not be provided on the side wall 120 of the silicone sleeve 12 , and the entire heat shrink tube 14 may be directly placed outside the side wall 120 , or may be a heat shrink tube. One end of 14 is sleeved on the side wall 120 , and the other end is sleeved on the camera 20 . When the accommodating groove 126 is not provided, after heating the heat shrink tube 14 , the heat shrink tube 14 can be shrunk to compress the silicone sleeve 12 until the outer surface of the heat shrink tube 14 is flush with the outer surface of the side wall 120 Or dented.

Specifically, the side wall 120 of this embodiment is also provided with convex ribs 128 extending along the axial direction of the silicone sleeve 12 . The convex ribs 128 can play a role in the process of installing the camera 20 and the seal 10 into the installation hole 320 . It has a guiding role, and can also strengthen the hardness of the side wall of the silicone sleeve 12, reduce the deformation of the silicone sleeve 12, and increase the tightness of the connection between the silicone sleeve 12 and the inner wall 322 of the mounting hole 320, further strengthening the dustproof and waterproof Effect.
