Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp lighting, in particular to a lens bracket component, a vehicle lamp module and a car. Background Art

[0002] The lens is the most basic optical element that makes up the lighting module in vehicle lamps. It is located at the front end of the lighting module. The sunlight hitting the lens will be refracted to form a focus or a near focus. The sunlight at different angles will be refracted through the lens to form a focal plane or a near focal plane. This focal plane area forms a high temperature due to the concentrated energy. If the material of the parts in the lighting module is not heat-resistant enough, the area intersecting with this focal plane will be melted or scorched after a long time, causing safety hazards.

[0003] At present, there are two main commonly used solutions. One is to prevent focusing by blocking with metal parts. That is, add a metal anti-focusing plate to the surface of the focused area on the lower side of the inner surface of the lens holder, or extend the rear metal parts such as the heat sink forward to the focused area of ​​the lens holder to block it. However, the solution of blocking the focusing area of ​​the lens holder with metal parts requires adding parts and installation procedures, which will increase the manufacturing cost of the product. Another solution is to prevent focusing by digging through the lens holder. That is, dig through the structure of the focused area on the lower side of the lens holder to avoid the focal plane area so that the lens holder will not be focused. However, this method requires digging through a larger area to completely avoid the focusing plane, so it will significantly weaken the structural strength of the parts, causing the parts to vibrate, and also affect the appearance.

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In the description of the present utility model, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0025] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0026] Example 1

[0027] Please refer to Figure 1 and Figure 3 As shown, this embodiment provides a lens holder assembly, which includes: a lens holder 100 and a lens 200, the lens 200 is arranged on the lens holder 100, a protective baffle 300 is arranged in the lens holder 100, the external light is converged by the lens 200 to form a focusing plane, and the protective baffle 300 is arranged in the light path between the lens 200 and the focusing plane.

[0028] The lens 200 is an optical element that can converge the light emitted through it. The conventional lens 200 has a spherical surface on one side and a flat surface or a concave surface or a convex surface on the other side. On the one hand, the lens 200 can protect the internal light source and other electronic components to prevent damage to the headlight. On the other hand, the lens 200 refracts the light emitted by the headlight light source so that the light emitted by the light source can illuminate the corresponding area and ensure the illumination of the lighting pattern. Please refer to Figure 3 As shown, in actual use, the spherical surface of the lens 200 faces outwards, directly facing the sunlight. Under the effect of the curvature of the lens 200 itself, the sunlight passing through the lens 200 from the outside will be focused. When the sunlight is focused on one point, it will form a high temperature. The lens bracket 100 on the headlight assembly is mostly made of plastic material, which is difficult to withstand the high temperature of the focused light and is prone to melting at high temperatures, which will cause damage to the lens bracket 100 on the headlight assembly, posing certain safety hazards. Please refer to Figure 1 and Figure 2 As shown, the lens support assembly provided in this embodiment blocks the focused sunlight passing through the lens 200 by setting a protective baffle 300 in the lens support 100, thereby protecting the lens support 100. In this embodiment, the protective baffle 300 is arranged on the optical path between the lens 200 and the focusing plane, which can block the external light passing through the lens 200 and prevent the light from being directly focused on the lens support 100. Due to the difference in factors such as the altitude of the sun and the position of the headlights, the focus of the sunlight after being refracted by the lens 200 is not the same. As the angle of sunlight changes, these focuses will form a focusing plane or an approximate focal plane (hereinafter referred to as the focusing plane). The lens support assembly provided in this embodiment sets the protective baffle 300 between the lens 200 and the focusing plane. When the refracted light is irradiated on the protective baffle 300, it is not fully focused. The energy of the light is relatively dispersed, so it will not cause excessive local temperature, thereby avoiding the situation where the lens support 100 is burned due to the lens 200 focusing sunlight.

[0029] Furthermore, in some implementations of this embodiment, the protective baffle 300 is detachably connected to the lens bracket 100 .

[0030] The protective baffle 300 can be detachably connected to the lens bracket 100 by any existing method such as threaded connection, stud connection, etc. On the one hand, the detachable connection structure can facilitate the adjustment of the position of the protective baffle 300 during installation, ensuring that the protective baffle 300 can block the focused light passing through the lens 200 to the greatest extent without affecting the normal lighting light of the headlight passing through the lens 200. On the other hand, the detachable connection structure also facilitates the replacement of the protective baffle 300. In some extreme cases, the protective baffle 300 may be damaged. In this case, only the protective baffle 300 needs to be replaced, and the lens bracket 100 can be reused, thereby increasing the service life of the lens bracket 100.

[0031] Optionally, in some implementations of the present embodiment, the protective baffle 300 includes a shielding portion and a connecting portion, the connecting portion is arranged at the edge of the shielding portion, and the connecting portion can be clamped on the lens bracket 100. Specifically, the protective baffle 300 includes a shielding portion for shielding the focused light and connecting portions arranged at the edges of both sides of the shielding portion, and the protective baffle 300 is detachably connected to the lens bracket 100 through the connecting portion. The inner side wall of the lens bracket 100 may be provided with a groove clamped with the connecting portion, and the detachable connection is achieved by clamping the connecting portion into the groove, which has a simple structure and is easy to install. The inner side wall of the lens bracket 100 may be provided with grooves for clamping the protective baffle 300 at different heights. During installation, the installation height of the protective baffle 300 can be adjusted as needed, and the sunlight is prevented from being focused on the protective baffle 300 after passing through the lens 200 to the greatest extent without affecting the lighting effect of the lighting light.

[0032] Optionally, in some other embodiments, the lens holder 100 and the protective baffle 300 are integrally formed.

[0033] Please refer to Figure 1 As shown, in this embodiment, the lens bracket 100 and the protective baffle 300 can be integrally formed by injection molding, additive manufacturing, etc., and the protective baffle 300 and the lens bracket 100 are both made of high temperature resistant materials. It should be noted that since the sunlight passing through the lens 200 does not form a highly concentrated focus on the protective baffle 300, it will not cause the local temperature of the protective baffle 300 to be too high. Therefore, the lens bracket 100 and the protective baffle 300 can withstand temperatures below 70°C-80°C to meet the use requirements. Existing high temperature resistant plastics and metals can meet the above requirements. During production, suitable materials can be selected according to actual needs to reduce production costs. The integral molding of the lens bracket 100 and the protective baffle 300 can also improve the connection strength of the protective baffle 300, and can prevent the protective baffle 300 from being damaged or falling due to external factors such as vibration and collision. The integral molding of the protective baffle 300 and the lens bracket 100 can also reduce the subsequent installation operation steps and improve the installation efficiency of the lens bracket assembly.

[0034] Please refer to Figure 1 As shown, in some implementations of this embodiment, the protective baffle 300 is located in the lower half area of ​​the lens holder 100 .

[0035] It can be understood that in actual use, sunlight always shines downward from the upper oblique direction and passes through the lens 200. Therefore, after being refracted and converged by the lens 200, a focusing point will be formed on the inner bottom wall of the lens holder 100, causing damage to the inner bottom wall of the lens holder 100. Therefore, the protective baffle 300 is set in the lower half of the lens holder 100 to block the light without affecting the lighting function. The protective baffle 300 is set at a certain height above the inner bottom wall of the lens holder 100, and can completely cover the path of the focused light. Ensure that the light is irradiated on the protective baffle 300 before it is highly focused to avoid the formation of a focus with higher energy.

[0036] Optionally, in some implementations of this embodiment, there is a gap between the protective baffle 300 and the lens 200 .

[0037] Please refer to Figure 3 As shown, in this embodiment, the front end of the protective baffle 300 is at a certain distance from the light incident surface of the lens 200 to prevent the light emitted by the light source from being blocked from passing through the primary optical element to the lens 200, thereby avoiding affecting the lighting effect of the headlight. At the same time, there is a gap between the lens 200 and the protective baffle 300, so that the protective baffle 300 is not easily visible from the outside, thereby ensuring a good appearance of the product.

[0038] Optionally, in some implementations of this embodiment, at least one of the protective baffle 300 and the lens bracket 100 is made of infrared transmitting material.

[0039] Infrared transmissive materials refer to materials that can transmit infrared radiation and infrared light. The use of infrared transmissive materials can prevent most of the infrared band of sunlight from being absorbed, thereby reducing the heat energy absorbed by the lens holder 100 and / or the protective baffle 300, further reducing the risk of the lens holder 100 being melted by focused sunlight, and the other properties and prices of this material are similar to those of the raw materials, and will not increase the production cost too much. It should be noted that infrared transmissive materials are a relatively mature prior art, so the specific types of infrared transmissive materials are not limited. During production, suitable materials can be used according to material strength, infrared light transmission efficiency and material cost.

[0042] The vehicle light module provided in this embodiment adopts the above-mentioned lens bracket assembly, which can effectively prevent sunlight from passing through the lens 200 and focusing on the lens bracket 100 to cause damage to the lens bracket 100, thereby ensuring the safety of the vehicle light module and improving the service life of the vehicle light module.
