[0034] The utility model discloses a sealing cover of a lamp, which can adapt to assembly holes of various apertures and shapes. In addition, the utility model also discloses a lamp and a vehicle with the sealing cover.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0037] Conventional lamps usually have mounting holes on their housings for mounting other components, such as optional testing equipment or other functional parts. When these mounting holes do not need to be mounted with other components, they will exist as through holes, which will affect the safety inside the lamp.

[0038] Therefore, it is necessary to design a sealing cover for sealing the assembly hole. Currently, the sealing cover is usually a hard plastic part, which is fixed at the assembly hole of the lamp housing by a rotating clamping installation method; in some methods, the sealing cover can also be made of rubber material and pressed into the assembly hole of the lamp housing by an interference fit.

[0039] Due to different spatial structure requirements, the size of the assembly hole on the lamp hole is uncertain and the type may be different. For example, the assembly hole may be a threaded hole. This requires the development of sealing covers with different aperture sizes and shapes, resulting in increased development costs.

[0040] Based on the above problems, the present application discloses a sealing cover of a lamp, which can be deformed under the extrusion of external force after being inserted into the assembly hole to seal the assembly hole.

[0041] Specific, combined Figures 1 to 4 As shown, the sealing cover 1 in the present application comprises a first section 11 , a second section 12 and a third section 13 .

[0042] Among them, the first section 11, the second section 12 and the third section 13 are arranged in sequence along the axial direction, that is, one end of the second section 12 is fixedly connected to the first section 11, and the other end of the second section 12 is fixedly connected to the third section 13, and the three are connected to form a structure extending along the axial direction. The second section 12 is an elastic section, which is used to cooperate with the assembly hole of the lamp. Specifically, the cooperation method includes but is not limited to interference fit. When the first section 11 is squeezed axially toward the second section 12, the first section 11 can be deformed along the radial surface, and the area of ​​the radial surface of the first section 11 increases. And / or, when the third section 13 is squeezed axially toward the second section 12, the third section 13 can be deformed along the radial surface, and the area of ​​the radial surface of the third section 13 increases.

[0043] It should be noted that the radial surface in the present application is a surface perpendicular to the axial direction, and after the first section 11 and the third section 13 are deformed, they can maintain the deformed state.

[0044] Through the above-mentioned arrangement, the first section 11 and the third section 13 in the present application can both be deformed along the radial surface, and the area along the radial surface increases after deformation. By increasing the area of ​​the first section 11 and / or the third section 13, assembly holes of various sizes can be covered, and assembly holes of different shapes and sizes can be adapted, thereby improving the application scope of the sealing cover 1 and effectively reducing the research and development cost of developing sealing covers for different assembly holes separately.

[0045] In some embodiments, the radial area of ​​the first section 11 after deformation is smaller than the radial area of ​​the third section 13 after deformation. When using the sealing cover 1, the first section 11 can be inserted into the interior of the lamp housing, while the third section 13 is exposed outside the lamp housing, so that the third section 13 with a larger area is used to block the outside of the lamp housing, which is more conducive to increasing the blocking surface and improving the sealing effect; and the larger blocking surface can also further increase the scope of application. After the first section 11 with a smaller area is inserted into the interior of the lamp housing, it can be deformed to offset the inner wall of the lamp housing, thereby ensuring the stability of the sealing cover 1 after installation on the lamp housing.

[0046] See also Figure 1 and Figure 3 As shown, the first section 11, the second section 12 and the third section 13 in the present application are coaxially arranged, and both the first section 11 and the third section 13 are arc surfaces. The coaxial arrangement is adopted to ensure that the circumferential sealing effect of the sealing cover 1 is more stable and avoid the occurrence of poor sealing. In addition, the coaxial arrangement method can ensure that the deformation size of the radial surface in each direction is basically the same during the deformation of the first section 11 and the third section 13.

[0047] In the present application, the first section 11 and the third section 13 are both arc surfaces, which can also ensure that the deformation sizes in all directions along the radial surface are substantially the same during the extrusion of the first section 11 and the third section 13, so as to better seal the assembly hole. It can be understood by those skilled in the art that the shapes of the first section 11, the second section 12 and the third section can be set according to different needs, and the above-mentioned arc surfaces are only exemplary descriptions, and other shapes are also within the protection scope.

[0048] In some embodiments, the first section 11 and / or the third section 13 are metal parts or plastic parts. The second section 12 is a rubber part. Before the sealing cover 1 is installed on the lamp housing, the first section 11 is a metal sheet or a plastic sheet in a gathered state, so that the first section 11 can smoothly pass through the sealing hole of the lamp housing. When the sealing cover 1 is installed in place, pressing the first section 11 and the third section 13 can deform the metal sheet or the plastic sheet, and the first section 11 and the third section 13 are unfolded after deformation, and the rubber material of the second section 12 fits tightly with the assembly hole to achieve sealing.

[0049] In the present application, the second section 12 is made of rubber material, and of course, it can also be made of other flexible materials. During the deformation of the first section 11, the position where the second section 12 is connected to the first section 11 can bend with the first section 11; and / or, during the deformation of the third section 13, the position where the second section 12 is connected to the third section 13 can bend with the third section 13. It can be understood that the second section 12 is made of a flexible material so that it can bend with the first section 11 and the third section 13, which can avoid hindering the deformation of the first section 11 and the third section 13 during the deformation of the first section 11 and the third section 13, that is, the second section 12 can change with the flexibility.

[0050] Combination Figure 2 and Figure 4 As shown, in some embodiments, the second section 12 is overlapped and bonded to the first section 11, and the second section 12 is overlapped and bonded to the third section 13. In addition, the second section 12 can be connected to the first section 11 and the third section 13 by integral molding or the like. As long as the first section 11, the second section 12 and the third section 13 can be fixedly connected in sequence, they are within the protection scope.

[0051] It should be noted that the second section 12 overlaps and bonds with the first section 11 and overlaps and bonds with the third section 13, which can ensure the stability of the sealing cover 1 after connection, while reducing the use of connectors, which is conducive to the miniaturization design of the sealing cover 1.

[0052] Combination Figures 5 to 9 As shown, the present application also discloses a lamp, comprising a lamp housing 2 and a sealing cover 1. The lamp housing 2 has an assembly hole 21, and the sealing cover 1 is used to connect with the assembly hole 21 and seal and cover the assembly hole 21. It should be noted that the sealing cover 1 is the sealing cover 1 disclosed in the above embodiment, and therefore, the lamp having the sealing cover also has all the above technical effects, which will not be described one by one here.

[0053] See also Figure 6 and Figure 7 It can be seen that the radial dimension of the first section 11 of the sealing cover 1 is initially smaller than the radial dimension of the assembly hole 21, and the radial dimension of the third section 13 is initially larger than the radial dimension of the assembly hole 21. Taking the assembly hole 21 as a circular through hole and the sealing cover 1 as a rotating body as an example, the first section 11 is an arc surface in the initial state, and the maximum length of the arc surface in the radial direction is smaller than the diameter of the assembly hole 21, and the third section 13 is an arc surface in the initial state, and the maximum length in the radial direction is greater than the diameter of the assembly hole 21.

[0054] By adopting the above-mentioned dimensional relationship setting, foolproof installation can be achieved, that is, only the first section 11 can be inserted into the assembly hole 21, while the second section 12 cannot be inserted, which effectively improves the assembly efficiency. In addition, the radial dimension of the first section 11 is smaller than that of the third section 13. When the deformation coefficient is the same, the third section 13 can obtain a larger deformation area.

[0055] Combination Figure 8 and Fig. 9 As shown, after the first section 11 and the third section 13 of the sealing cover 1 are deformed, the first section 11 fits with the inner wall of the lamp housing 2, and the third section 13 fits with the outer wall of the lamp housing 2. After the first section 11 fits with the inner wall of the lamp housing 2, and the third section 13 fits with the outer wall of the lamp housing 2, the sealing cover 1 and the lamp housing 2 can be clamped, that is, the first section 11 and the third section 13 are used to limit the sealing cover 1 along the axial direction of the assembly hole 21, so that the sealing cover 1 is fixed on the lamp housing 2. In this way, not only can the sealing cover 1 be used to block the assembly hole 21 of the lamp housing 2, but also the sealing cover 1 can be fixed on the lamp housing 2 by its own deformation, without the need to fix the sealing cover 1 additionally, so that the function is integrated and the cost is further reduced.

[0056] In addition, the present application also discloses a vehicle, including the lamp disclosed in the above embodiments. Therefore, the vehicle having the lamp also has all the above technical effects, which will not be described one by one here.

[0057] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0058] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
