Sealing gasket and camera assembly

Abstract

The application provides a sealing gasket and a camera assembly. The sealing gasket and the mounting piece are in close contact and sealed to seal a wire hole on the mounting piece. The sealing gasket comprises a main body and a first sealing lip. The main body is located between the camera and the mounting piece. The main body is provided with a wire outlet hole which is in communication with the wire hole. The first sealing lip is extended from the main body and surrounds the periphery of the wire outlet hole. When the first sealing lip is in close contact and sealed with the mounting piece, the first sealing lip surrounds the periphery of the wire hole to seal the wire hole. Compared with the way of sealing the wire hole by inserting a plug into the wire hole of the mounting piece, the sealing gasket has high size tolerance for the wire hole, solves the problem of sealing failure caused by the size of the wire hole, and improves the sealing effect. Meanwhile, when the camera side wire is connected, the connecting wire of the camera can be pressed and then passed out after the first sealing lip, so that the sealing gasket is suitable for the camera with bottom wire and side wire, and the cost is saved without the need to purchase the camera according to the assembly scene.

Description

Technical Field

[0001] This application relates to the field of sealing, and more particularly to a sealing gasket and a camera assembly. Background Technology

[0002] Cameras of the same model offer two installation methods depending on the installation scenario: bottom-out and side-out. Bottom-out installation requires drilling holes in the mounting bracket for cable routing. Its advantage is that the connecting cables are not exposed after camera installation, contributing to a cleaner, more aesthetically pleasing product and protecting the wiring harness from damage. Side-out installation does not require drilling holes in the mounting bracket; the cables are routed externally after installation. Its advantages include simple deployment and easier after-sales maintenance. Both cable routing options are used in practice, and the choice is generally determined by the specific application scenario.

[0003] In related technologies, bottom-out cameras have an integrated sealing plug on their connecting cable. This sealing plug is inserted into a mounting hole on the mounting surface to achieve a seal. However, the sealing plug has strict requirements on the size of the mounting hole, which can easily lead to seal failure. Furthermore, bottom-out and side-out cameras are not interchangeable, requiring the purchase of cameras with different cable exit methods depending on the installation scenario, thus increasing costs. Utility Model Content

[0004] This application provides a sealing gasket and a camera assembly. The sealing gasket has better sealing performance and is suitable for cameras with both bottom and side cable exits.

[0005] This application provides a sealing gasket for sealing against a mounting component that carries a camera, thereby sealing a cable passage hole on the mounting component. The cable passage hole is for the camera's connecting cable to pass through. The sealing gasket includes a main body and a first sealing lip. The main body is located between the camera and the mounting component. The main body has a cable exit hole that communicates with the cable passage hole. The first sealing lip extends from the main body and surrounds the periphery of the cable exit hole. When the first sealing lip is sealed against the mounting component, the first sealing lip surrounds the periphery of the cable passage hole.

[0006] Furthermore, the first sealing lip includes an inner side surface near the outlet hole and an outer side surface opposite to the inner side surface, wherein the angle between the inner side surface and the vertical direction is greater than the angle between the outer side surface and the vertical direction.

[0007] Furthermore, the sealing gasket also includes a second sealing lip, which surrounds the periphery of the outlet hole, and the first sealing lip surrounds the outside of the second sealing lip.

[0008] Furthermore, the first height of the first sealing lip extending from the main body is greater than the second height of the second sealing lip extending from the main body.

[0009] Furthermore, the sealing gasket also includes a protrusion extending from the main body, the protrusion and a portion of the second sealing lip forming a first recessed groove, the first recessed groove being located on the outer side of the cable outlet in the radial direction and communicating with the cable outlet, and a portion of the second sealing lip being located on the outer side of the first recessed groove in the radial direction. When the camera is in the side-outlet state, the connecting wire squeezes the second sealing lip, and the first recessed groove is used to accommodate the connecting wire.

[0010] Furthermore, the convex bulge, a portion of the first sealing lip, and a portion of the second sealing lip form a second recessed groove. Along the radial direction of the cable outlet, the second recessed groove and the first recessed groove are located on opposite sides of the portion of the second sealing lip. When the camera is in the side-outlet state, the connecting wire squeezes the second sealing lip, and the first recessed groove and the second recessed groove are used to accommodate the connecting wire.

[0011] Furthermore, the sealing gasket also includes a fixing part extending from the main body and a buckle disposed on the fixing part. The fixing part forms a cable outlet channel, which communicates with the cable outlet hole to allow the connecting cable to pass through. The fixing part is assembled into the through hole of the camera housing, and the buckle is fastened and fixed to the housing.

[0012] Furthermore, the main body is provided with a first assembly hole for the fastener to pass through and be assembled to the second assembly hole of the mounting member. The sealing gasket also includes a third sealing lip surrounding the periphery of the first assembly hole, and the third sealing lip fits and seals against the mounting member.

[0013] Furthermore, the first assembly hole is connected to the third assembly hole of the camera, and the fastener passes through the third assembly hole and the first assembly hole in sequence before being assembled in the second assembly hole.

[0014] This application also provides a camera assembly, including a camera and the sealing gasket.

[0015] The sealing gasket of this embodiment surrounds the cable exit hole via a first sealing lip. When the first sealing lip is in contact with the mounting component for sealing, it surrounds the cable exit hole to seal it. Compared to the method of inserting a plug into the cable exit hole of the mounting component, this method has greater tolerance for the size of the cable exit hole, solving the problem of sealing failure caused by the size of the cable exit hole and improving the sealing effect. At the same time, when the camera cable exits from the side, the camera cable can be pushed through the first sealing lip and then passed through. The sealing gasket is compatible with both bottom-exit and side-exit cameras, eliminating the need to purchase additional cameras according to the assembly scenario and saving costs.

[0026] Here, in conjunction with the accompanying drawings, the technical solutions in the embodiments (or "embodiment modes") of the present application will be clearly and completely described. When the following description involves the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0027] If there are terms related to directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), then such terms are only used to explain the relative positional relationships and movement conditions between components in a specific posture (as shown in the accompanying drawings); if this specific posture changes, then the directional indication or positional relationship also changes accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0028] Refer Figures 1 to 6 , the embodiment mode of the present application provides a camera assembly 100, including a sealing gasket 1 and a camera 2. The camera 2 is installed on a mounting member 3. The mounting member 3 is provided with a wire passing hole 31 for the connecting wire 21 of the camera 2 to pass through. The sealing gasket 1 is used to fit and seal with the mounting member 3 carrying the camera 2 to seal the wire passing hole 31.

[0029] The mounting member 3 can be a vehicle body or other support structures.

[0030] The sealing gasket 1 can be made of silica gel, rubber, etc.

[0031] The sealing gasket 1 includes a main body portion 11 and a first sealing lip 12. The main body portion 11 is located between the camera 2 and the mounting member 3. The main body portion 11 is provided with a wire outlet hole 111. The wire outlet hole 111 is communicated with the wire passing hole 31 for the connecting wire 21 of the camera 2 to pass through. The first sealing lip 12 extends from the main body portion 11 and surrounds the periphery of the wire outlet hole 111. When the first sealing lip 12 fits and seals with the mounting member 3, the first sealing lip 12 surrounds the periphery of the wire passing hole 31.

[0032] The sealing gasket 1 surrounds the periphery of the wire outlet hole 111 through the first sealing lip 12. When the first sealing lip 12 fits and seals with the mounting member 3, the first sealing lip 12 surrounds the periphery of the wire passing hole 31 to seal the wire passing hole 31 and prevent water leakage at the wire passing hole 31. Compared with the method of using a rubber plug inserted into the wire passing hole of the mounting member to achieve sealing, it has a greater tolerance for the size of the wire passing hole 31, solves the problem of sealing failure caused by the size of the wire passing hole 31, and improves the sealing effect; at the same time, refer Figure 3 When the camera 2 exits from the side, the connecting wire 21 of the camera 2 can be squeezed through the first sealing lip 12 and then passed through. The first sealing lip 12 does not affect the passage of the connecting wire 21. The sealing gasket 1 is compatible with both bottom-exit and side-exit cameras 2, eliminating the need to purchase additional cameras 2 according to the assembly scenario, thus saving costs. The sealing gasket 1 and the connecting wire 21 are supplied separately, simplifying the structure of the connecting wire 21 and increasing its versatility.

[0033] In one embodiment, the sealing gasket 1 further includes a second sealing lip 13, which surrounds the periphery of the outlet hole 111, and the first sealing lip 12 surrounds the outside of the second sealing lip 13.

[0034] The first sealing lip 12 and the second sealing lip 13 provide two seals when the second sealing lip 13 surrounds the periphery of the wire outlet 111, further improving the sealing effect and effectively preventing water leakage at the wire outlet 31. Simultaneously, even when the wire outlet 111 is larger than the diameter of the space enclosed by the second sealing lip 13, the first sealing lip 12 still provides a seal, ensuring the sealing effect and effectively preventing water leakage at the wire outlet 31. Meanwhile, [further details omitted]. Figure 3 When the camera 2 exits from the side, the connecting wire 21 of the camera 2 can be squeezed through the second sealing lip 13 and then passed through. The second sealing lip 13 does not affect the passage of the connecting wire 21. The sealing gasket 1 is compatible with both bottom-exit and side-exit cameras 2, so there is no need to purchase a separate camera 2 according to the assembly scenario, thus saving costs.

[0035] The first sealing lip 12 and the second sealing lip 13 can be set separately or simultaneously. When only the first sealing lip 12 is set, the first sealing lip 12 can also be located at the position of the second sealing lip 13.

[0036] In one embodiment, the main body 11 is provided with a first assembly hole 112 for the fastener 4 to pass through and be assembled to the second assembly hole 32 of the mounting member 3. The sealing gasket 1 also includes a third sealing lip 14 surrounding the periphery of the first assembly hole 112, the third sealing lip 14 fitting and sealing the mounting member 3 to seal the second assembly hole 32.

[0037] The sealing gasket 1 can also seal the second assembly hole 32 to prevent water leakage at the second assembly hole 32, thereby providing better sealing performance.

[0038] It should be noted that in this specification, the concept of the lip edge can also be understood as the skirt edge. For example, the first sealing lip edge 12 can also be the first sealing skirt edge, the second sealing lip edge 13 can also be the second sealing skirt edge, and the third sealing lip edge 14 can also be the third sealing skirt edge.

[0039] In one embodiment, the first assembly hole 112 is located inside the first sealing lip edge 12 and outside the second sealing lip edge 13.

[0040] In one embodiment, one or more first assembly holes 112 can be provided, and the quantity can be adjusted according to actual needs.

[0041] In one embodiment, the camera 2 is provided with a third assembly hole 22, and the first assembly hole 112 is communicated with the third assembly hole 22. The fixing member 4 passes through the third assembly hole 22 and the first assembly hole 112 in sequence and is assembled in the second assembly hole 32. The setting of the fixing member 4 facilitates the assembly and disassembly of the camera 2.

[0042] In another embodiment, the camera 2 can also be snap-fixed to the mounting member 3.

[0043] Refer Figures 7 to 8 , in one embodiment, the first sealing lip edge 12 includes an inner side surface 121 close to the wire outlet hole 111 and an outer side surface 122 disposed opposite to the inner side surface 121. The included angle between the inner side surface 121 and the vertical direction is greater than the included angle between the outer side surface 122 and the vertical direction. That is, in the natural state, the first sealing lip edge 12 is inclined as a whole towards the direction of the outer side surface 122. When the first sealing lip edge 12 is pressed, it will deform as a whole towards the direction of the outer side surface 122, preventing the first sealing lip edge 12 from failing to seal due to inconsistent deformation directions after being pressed.

[0044] Refer Figure 5 and Figures 9 to 10 , in one embodiment, the sealing gasket 1 further includes a fixing portion 16 extending from the main body portion 11 and a buckle 17 provided on the fixing portion 16. The fixing portion 16 encloses a wire outlet channel 161, and the wire outlet channel 161 is communicated with the wire outlet hole 111 for the connecting wire 21 to pass through. The fixing portion 16 is assembled into the through hole 231 of the housing 23 of the camera 2, and the buckle 17 is snap-fixed to the housing 23, increasing the stability of the sealing gasket 1, and the sealing gasket 1 is convenient for assembly and disassembly.

[0045] In another embodiment, the sealing gasket 1 is not fixed to the camera 2, but can be fixed to the mounting component 3. After the camera 2 is fixed to the mounting component 3, the sealing gasket 1 can be fitted and sealed to the outer shell 23 of the camera 2.

[0046] In one embodiment, the first height h1 of the first sealing lip 12 extending from the main body 11 is greater than the second height h2 of the second sealing lip 13 extending from the main body 11, which can better adapt to the case where the surface of the mounting member 3 is curved.

[0047] In one embodiment, the sealing gasket 1 further includes a protrusion 15 extending from the main body 11. The protrusion 15 and a portion of the second sealing lip 13 form a first recessed groove 151. The first recessed groove 151 is located radially outside the outlet hole 111 and communicates with the outlet hole 111, and a portion of the second sealing lip 13 is located radially outside the first recessed groove 151.

[0048] Combination Figure 3 When the camera 2 is in the side-out state, the connecting wire 21 presses against the second sealing lip 13, and the first recessed groove 151 is used to accommodate the connecting wire 21, which can reduce the gap between the camera 2 and the mounting part 3. This not only increases the stability of the camera 2, but also avoids the problem that the third sealing lip 14 cannot fit with the mounting part 3.

[0049] When the camera 2 is in the bottom-out state, the second sealing lip 13 located on the outer side of the first recess 151 in the radial direction fits and seals with the mounting part 3, which can prevent water from entering the first recess 151.

[0050] In one embodiment, the convex bulge 15, a portion of the first sealing lip 12, and a portion of the second sealing lip 13 form a second recessed groove 152. Along the radial direction of the outlet hole 111, the second recessed groove 152 and the first recessed groove 151 are located on opposite sides of the portion of the second sealing lip 13. That is, the second sealing lip 13 separates the first recessed groove 151 and the second recessed groove 152.

[0051] Combination Figure 3 When the camera 2 is in the side-out state, the connecting wire 21 presses against the second sealing lip 13. The first recessed groove 151 and the second recessed groove 152 are used to accommodate the connecting wire 21, which can reduce the gap between the camera 2 and the mounting part 3. This not only increases the stability of the camera 2, but also avoids the problem that the third sealing lip 14 cannot fit with the mounting part 3.

[0052] When the camera 2 is in the bottom cable exit state, the second sealing lip 13 located on the outer side of the first recess 151 in the radial direction is in contact with and sealed to the mounting member 3, and the first sealing lip 12 located on the outer side of the second recess 152 in the radial direction is in contact with and sealed to the mounting member 3, which can prevent water from entering the first recess 151 and the second recess 152.

[0053] In one embodiment, the first recessed groove 151 is connected to the second recessed groove 152, that is, the second sealing lip 13 is not provided between the first recessed groove 151 and the second recessed groove 152, and the second sealing lip 13 is not closed in the circumferential direction. In this case, it is convenient for the cable to run when the cable exits from the side, and when the cable exits from the bottom, it is sealed by the first sealing lip 12 to prevent water from entering the first recessed groove 151 and the second recessed groove 152.

[0054] When the camera 2 is in the side-outlet state, the connecting line 21 may or may not squeeze the first sealing lip 12.

[0055] In one embodiment, the housing 23 of the camera 2 is provided with a receiving groove (not shown) to receive the protrusion 15.

[0056] In one embodiment, the convex bulge 15 abuts against the housing 23 to improve the sealing effect and also increase the stability between the sealing gasket 1 and the camera 2.

[0057] In one embodiment, the fixing part 16 has a certain height, the height of the protrusion 15 is less than the height of the fixing part 16, and the buckle 17 is located above the protrusion 15 along the protruding direction of the fixing part 16.

[0058] The sealing gasket 1 is sealed to the surface of the mounting component 3 by the first sealing lip 12, which has a large tolerance for the size of the wire hole 31, improving versatility and sealing performance; the sealing performance is improved by the two seals; at the same time, the first sealing lip 12 and the second sealing lip 13 do not affect the side exit of the camera 2, so that the camera 2 has both bottom and side exit methods, and different exit methods can be selected according to different scenarios, which improves versatility and reduces costs.

[0059] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
