Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and more specifically, to a vehicle light and a vehicle. Background Technology

[0002] The LED light source of a vehicle headlight is fixed to a light panel, which is typically mounted on the housing using snap-fit ​​or threaded connections. During the installation, transportation, and use of vehicle headlights, contact and friction with air and people generate a large amount of static electricity. Because the components on the light panel are small, highly integrated, have thin insulating films, and low electrostatic breakdown voltage, these components are highly susceptible to breakdown or failure due to static electricity when directly fixed to the housing, leading to light panel malfunction. This can not only cause temporary or permanent failure of some signal functions of the headlight but also pose serious safety hazards.

[0003] To prevent components in vehicle lights from failing due to electrostatic discharge, existing technologies employ two main measures: one is to add a shielding box to the light panel for protection, and the other is to add a ground wire in the light wiring harness that contacts the internal metal / aluminized parts. However, the former suffers from large space requirements and low utilization, while the latter leads to an increase in the number of components developed and higher costs.

[0004] Therefore, how to effectively reduce the risk of breakdown or failure of internal components of vehicle lights due to static electricity has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0044] The core of this utility model is to disclose a vehicle lamp that effectively reduces the risk of breakdown or failure of internal components due to static electricity.

[0045] Another key aspect of this invention is the disclosure of a vehicle that includes the aforementioned headlights.

[0046] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the embodiments below are not limited to those necessary for the solution of the utility model as described in the claims. It should be noted that, for ease of description, only the parts relevant to the utility model are shown in the drawings. Unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0047] Creepage distance refers to the shortest distance from two adjacent conductors or a single conductor to the insulating edge of a metal surface. In this invention, the creepage distance refers to the shortest distance from which static electricity enters the vehicle lamp from the outside and reaches the lamp panel 400. The arrows in each figure indicate the creepage path of static electricity.

[0048] Combination Figures 1-15The vehicle light disclosed in this utility model includes a lamp housing 100, a lamp cover, a bracket 200, a lamp plate 400, and a connector 300. The lamp housing 100 includes a housing body and a first connecting part. The housing body is connected to the lamp cover and forms an installation space. A first connecting hole 101 is provided on the housing body. The first connecting part includes a first positioning tube post 110 with an annular cross-section. The first positioning tube post 110 is disposed in the installation space and connected to the housing body and communicates with the first connecting hole 101. A plurality of first protruding rings 111 are protruding on the outer peripheral wall of the first positioning tube post 110. Each first protruding ring 111 is arranged sequentially along the axial direction of the first positioning tube post 110. The bracket 200 includes a bracket body and a second connecting part. The lamp panel 400 and the second connecting part are both connected to the bracket body. The lamp panel 400, the second connecting part and the bracket body are all arranged in the installation space. The second connecting part is provided with a second connecting hole 201 and a positioning ring groove 210. The second connecting hole 201 is located in the middle of the positioning ring groove 210 and communicates with the first connecting hole 101. The connector 300 passes through the first connecting hole 101 and is threadedly connected to the second connecting hole 201. The first positioning tube 110 is embedded in the positioning ring groove 210.

[0049] Combination Figure 11 and Figure 12 When external static electricity passes through the first connection hole 101, under the action of the first positioning post 110, it needs to pass through the inner circumferential wall, bottom wall, and outer circumferential wall of the positioning ring groove 210 in sequence before reaching the installation space, greatly extending the creepage distance. By adjusting the axial dimensions of the first positioning post 110 and the positioning ring groove 210, the creepage distance can be adjusted. Typically, the creepage distance is set to be greater than or equal to 25mm to keep it within the static electricity elimination range and avoid affecting the function of the lamp board 400.

[0050] Compared to existing technologies, the vehicle lamp disclosed in this utility model effectively extends the creepage distance through the embedded cooperation of the first positioning post 110 and the positioning ring groove 210, thereby preventing static electricity from being transferred to the lamp plate 400, preventing static electricity failure, and greatly improving the safety performance of the vehicle lamp. At the same time, by setting the first convex ring 111, a tight fit between the first connecting part and the second connecting part is ensured, reducing the probability of static electricity entering the installation space. In addition, the vehicle lamp disclosed in this utility model also has the advantages of low cost, simple structure, and small space occupation.

Along the axial direction of the second connecting hole 201, each first protruding ring 111 is embedded in each first ring groove 214 in a corresponding manner, so that a wavy gap is formed between the outer peripheral wall of the positioning ring groove 210 and the outer peripheral wall of the first positioning tube 110, thereby greatly extending the creepage distance.

[0053] The first convex ring 111 directly abuts against the outer peripheral wall of the positioning ring groove 210, or, in one embodiment, in combination with Figure 7 and Figure 8 Multiple second protruding rings 212 are provided on the outer peripheral wall of the positioning ring groove 210. Each second protruding ring 212 is arranged sequentially along the axial direction of the positioning ring groove 210. Figure 10 and Figure 11 Along the axial direction of the second connecting hole 201, the first convex ring 111 and the second convex ring 212 are staggered and abut against each other, so that there are multiple tightly fitted abutment positions between the positioning ring groove 210 and the first positioning tube post 110, thereby achieving the isolation of static electricity and reducing the probability of static electricity entering the installation space.

[0054] To further extend the creepage distance, the first connecting part also includes a second positioning post 120 with an annular cross-section. The second positioning post 120 is disposed in the installation space and connected to the housing body. The second positioning post 120 is coaxially arranged with the first positioning post 110 and is disposed on the outer ring of the first positioning post 110. The second positioning post 120 is sleeved on the outside of the second connecting part. The creepage distance can be further extended and the anti-static capability of the vehicle lamp can be improved through the embedded cooperation between the second positioning post 120 and the second connecting part.

[0055] Accordingly, multiple third protruding rings 121 can be provided on the inner peripheral wall of the second positioning column 120. The third protruding rings 121 are arranged sequentially along the axial direction of the second positioning column 120 to extend the creepage distance on the inner peripheral wall of the second positioning column 120.

[0056] In one embodiment, a plurality of second annular grooves 213 are provided on the outer peripheral wall of the second connecting part, and each second annular groove 213 is arranged sequentially along the axial direction of the second connecting hole 201; along the axial direction of the second connecting hole 201, each third protruding ring 121 is embedded in each second annular groove 213 in a corresponding manner, so that a wavy gap is formed between the outer peripheral wall of the second connecting part and the inner peripheral wall of the second positioning tube 120, thereby greatly extending the creepage distance.

[0057] In another embodiment, the third protruding ring 121 abuts against the outer peripheral wall of the second connecting part, or, a plurality of fourth protruding rings 211 are provided on the outer peripheral wall of the second connecting part, and each fourth protruding ring 211 is arranged sequentially along the axial direction of the second connecting hole 201; along the axial direction of the second connecting hole 201, the third protruding ring 121 and the fourth protruding ring 211 are staggered and abut against each other, so that there are multiple tightly fitted abutting positions between the second connecting part and the second positioning tube post 120, thereby achieving the isolation of static electricity and reducing the probability of static electricity entering the installation space.

[0058] The first convex ring 111 and the third convex ring 121 described above are integrally formed with the first positioning post 110 and can be manufactured by integral molding. The second convex ring 212 and the fourth convex ring 211 are integrally formed with the second positioning post 120 and can be manufactured by integral molding.
