A vehicle lamp structure, a vehicle lamp module and a vehicle

Abstract

This utility model discloses a vehicle lamp structure, a vehicle lamp module, and a car, including: a lamp holder; and a lamp body assembly mounted on the lamp holder via a rotating shaft. The axis of the rotating shaft extends laterally, and the center of gravity of the lamp body assembly is located below the rotating shaft. The lamp body assembly can rotate relative to the lamp holder around the rotating shaft under its own weight to maintain the light emission direction. In the technical solution of this utility model, when the front wheels of a vehicle suddenly lift up due to a speed bump or a sudden road surface bulge, the lamp body assembly does not lift up under its own weight, thus maintaining a stable light emission direction and preventing it from lifting up with the front of the vehicle, avoiding glare for oncoming vehicles and pedestrians. Simultaneously, by stabilizing the headlight illumination angle, it improves vehicle driving safety. This utility model, through the stabilizing structure of the headlight body, suppresses the sudden lifting of the headlight's light path due to speed bumps or road surface bulges. This stabilizing mechanism can be achieved simply by setting the center of gravity of the lamp body assembly; the structure is simple, safe, and reliable.

Description

Technical Field

[0001] This utility model relates to the field of automotive lighting, and in particular to an automotive lighting structure, an automotive lighting module, and an automobile. Background Technology

[0002] Existing and traditional light sources are generally statically arranged, especially with the increasing use of LED light-emitting chips, where the light source and related optical components are directly or indirectly fixed. This causes the headlight beam to suddenly rise when a car goes over a speed bump or a sudden bulge in the road, and the low beam beam will also rise suddenly, causing pedestrians or drivers ahead to be shone with the light, resulting in eye discomfort and unpleasantness. At the same time, the unstable beam of the headlights also poses a risk to driving and affects driving safety.

[0003] In summary, the problems existing in the relevant technologies urgently need to be solved. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a vehicle lamp structure, a vehicle lamp module and a car.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] Firstly, a vehicle headlight structure includes:

[0007] Lamp holder;

[0008] The lamp body assembly is mounted on the lamp holder via a rotating shaft. The axis of the rotating shaft extends laterally, and the center of gravity of the lamp body assembly is located below the rotating shaft. The lamp body assembly can rotate relative to the lamp holder around the rotating shaft under its own weight to maintain the light emission direction.

[0009] In conjunction with the first aspect, in some implementations of the first aspect, the lamp assembly is able to rotate downwards relative to the lamp holder from its original position around the pivot axis under its own gravity when the front of the vehicle is lifted, so as to maintain the light emission direction.

[0010] In combination with the first aspect and the above-described implementations, in some implementations of the first aspect, the lamp holder is provided with a limiting structure, which is used to cooperate with the lamp body assembly to restrict the lamp body assembly from rotating upward about the rotating axis relative to the lamp holder from its original position.

[0011] In combination with the first aspect and the above-described implementations, in some implementations of the first aspect, the limiting structure includes a limiting rib disposed on the lamp holder, the limiting rib extending from the lamp holder toward the lamp body assembly, and cooperating with the top of the lamp body assembly above the rotating shaft.

[0012] In combination with the first aspect and the above-described implementations, in some implementations of the first aspect, the lamp holder is provided with a pivot seat on both sides of the lamp body assembly, and the lamp body assembly is mounted on the pivot seat via pivots on both sides.

[0013] In combination with the first aspect and the above-described implementations, in some implementations of the first aspect, the lamp body assembly includes a first reflector lampshade, the lamp holder is provided with a first light source, the rear side of the first reflector lampshade is provided with a light source avoidance hole, and the first light source passes through the light source avoidance hole and is located inside the reflector lampshade.

[0014] In combination with the first aspect and the above-described implementations, in some implementations of the first aspect, the lamp assembly includes a second reflector and a second light source, the second reflector and the second light source being fixedly connected to form an assembly.

[0015] In combination with the first aspect and the above-mentioned implementation methods, in some implementation methods of the first aspect, the lamp holder is provided with a damper, and the rotating shaft is connected to the damper through a transmission structure.

[0016] In a second aspect, a vehicle lighting module includes the vehicle lighting structure described in any implementation of the first aspect.

[0017] Thirdly, an automobile includes the headlight module described in any implementation of the second aspect.

[0018] One of the above technical solutions has at least one of the following advantages or beneficial effects:

[0019] In this invention, the lamp assembly is mounted on the lamp holder via a pivot, and the center of gravity of the lamp assembly is positioned below the pivot. This ensures that when the vehicle's front wheels roll over a speed bump or a sudden road surface bulge, the lamp assembly remains stable under its own weight, preventing it from lifting up with the vehicle's front end and avoiding glare for oncoming vehicles and pedestrians. Furthermore, by stabilizing the headlight's beam angle, driving safety is improved. This invention, through its stabilizing structure, suppresses the sudden lifting of the headlight beam due to speed bumps or road surface bulges. This stabilizing mechanism is achieved simply by adjusting the center of gravity of the lamp assembly, resulting in a simple, safe, and reliable structure.

[0030] in, Figure 3 The reference direction coordinate system of this utility model embodiment is given below, in conjunction with Figure 3The embodiments of this utility model will be described in the directions shown.

[0031] See Figures 1-4 This utility model provides a vehicle lamp structure, particularly suitable for automotive headlights. The lamp structure includes a lamp holder 100 and a lamp body assembly 200. The lamp holder 100 is the base of the entire lamp structure and can be directly or indirectly installed on the vehicle body during use. The lamp body assembly 200 is mounted on the lamp holder 100 via a pivot 201. The axis of the pivot 201 extends laterally, i.e., along the width direction of the vehicle body. The center of gravity of the lamp body assembly 200 is located below the pivot 201, for example, directly below the pivot 201. From the perspective of mass distribution, the lamp body assembly 200 is vertically mounted on the lamp holder 100. The lamp body assembly 200 can rotate relative to the lamp holder 100 around the pivot 201 under its own weight to maintain the light emission direction. In other words, after the lamp holder 100 is adjusted in posture, for example, the front end of the lamp holder 100 is raised, the lamp body assembly 200 can rotate relative to the lamp holder 100 around the rotation axis 201 under its own gravity to maintain the light output direction.

[0032] Combination Figures 1-4 In this invention, the headlight structure is installed at the front of the vehicle body. The headlight assembly 200 is mounted on the lamp holder 100 via a pivot 201. Furthermore, the center of gravity of the headlight assembly 200 is positioned below the pivot 201. This ensures that when the vehicle's front wheels roll over a speed bump or a sudden road surface bulge, the headlight assembly 200 remains stationary under its own weight, maintaining a stable light output direction and preventing it from lifting with the vehicle's front end. This avoids glare for oncoming vehicles and pedestrians and improves vehicle safety by stabilizing the headlight's illumination angle. This invention, through its stabilizing headlight structure, suppresses the sudden lifting of the headlight's beam due to speed bumps or road surface bulges. This stabilizing mechanism is achieved simply by adjusting the center of gravity of the headlight assembly 200, resulting in a simple, safe, and reliable structure.

[0033] In some embodiments, see Figures 1-4 When the front of the vehicle is lifted, the lamp assembly 200 can rotate downwards around the pivot 201 relative to the lamp holder 100 from its original position under its own gravity to maintain the light emission direction. Specifically, the lamp assembly 200 is installed at the front of the vehicle. When the front wheels of the vehicle drive over a speed bump or a suddenly raised road surface and the vehicle is suddenly lifted, the lamp holder 100 rotates relative to the ground plane, but the lamp assembly 200 does not lift up under its own gravity, thus maintaining a stable light emission direction and not lifting up with the front of the vehicle.

[0034] In some embodiments, see Figure 3The lamp holder 100 is provided with a limiting structure 101, which is used to cooperate with the lamp body assembly 200 to limit the lamp body assembly 200 from rotating upward about the pivot 201 relative to the lamp holder 100 from its original position, thereby preventing the lamp cover from rotating upward.

[0035] Further, see Figure 3 The limiting structure 101 includes a limiting rib disposed on the lamp holder 100. The limiting rib extends from the lamp holder 100 toward the lamp body assembly 200 and engages with the top of the lamp body assembly 200 above the rotating shaft 201. The limiting rib forms a limit at the top of the lamp body assembly 200 to prevent the lamp cover from rotating upward uncontrollably.

[0036] In some embodiments, see Figure 1 , Figure 2 , Figure 4 The lamp holder 100 has pivot seats 102 on both sides of the lamp body assembly 200. The lamp body assembly 200 is mounted on the pivot seats 102 via pivots 201 on both sides. For example, in Figure 4 In the illustrated embodiment, the end of the rotating shaft 201 is an integrally formed ball head, which is mounted on the rotating shaft seat 102. The rotating shafts 201 on both sides of the lamp body assembly 200 are coaxially arranged, jointly defining the rotation axis of the lamp body assembly 200. The lamp body assembly 200 is supported by the rotating shafts 201 on both sides, effectively improving the structural stability of the lamp body assembly 200.

[0037] In some embodiments, see Figure 3 The lamp assembly 200 includes a first reflector lampshade 202, and a lamp holder 100 is provided with a first light source 204. A light source avoidance hole 203 is provided on the rear side of the first reflector lampshade 202. The first light source 204 passes through the light source avoidance hole and is located inside the reflector lampshade. The light from the first light source 204 can be reflected by the first reflector lampshade 202 and emitted outwards along the light emission direction. When the front wheels of the vehicle run over a speed bump or a suddenly raised road surface and are suddenly lifted, the first reflector lampshade 202 does not lift under its own weight, thus maintaining a stable light emission direction and preventing it from lifting with the front of the vehicle. During this process, the first light source 204 does not move with the first reflector lampshade 202. In this embodiment, the lamp assembly 200 includes the first reflector lampshade 202 but does not include the first light source 204; that is, the light emission direction of the lamp assembly 200 is automatically adjusted and maintained by the vertically mounted first reflector lampshade 202. The center of gravity of the first reflector lampshade 202 can be set directly below the center of the pivot 201 by locally adding a counterweight structure or reducing its thickness. In this embodiment, the lamp body assembly 200 includes the first reflector lampshade 202 but does not include the first light source 204, which makes it easier to control the center of gravity, and makes the installation of the second light source and the lamp holder 100 more convenient and stable.

[0038] In some embodiments, the lamp assembly 200 includes a second reflector and a second light source, which are fixedly connected to form a single assembly. In this embodiment, the lamp assembly 200 includes a second reflector and a second light source. When the front wheels of a vehicle roll over a speed bump or a suddenly raised road surface and lift up abruptly, the overall posture of the lamp assembly 200 remains stable under its own gravity, thus maintaining a stable light emission direction and preventing it from lifting up with the front of the vehicle. In this embodiment, the lamp assembly 200 includes a second reflector and a second light source, allowing it to function as a single, integrated assembly, such as a projector headlight. This results in better light emission and greater flexibility in selection.

[0039] In some embodiments, see Figure 4 The lamp holder 100 is equipped with a damper 103, and the rotating shaft 201 is connected to the damper 103 via a transmission structure. For example, in Figure 4 In this embodiment, the rotating shaft 201 is provided with an integrally injection-molded sector tooth 205, and the damper 103 of the lamp holder 100 is provided with a gear, which meshes with the sector tooth for transmission. In this embodiment, damping is increased by the rotating shaft 201 to prevent excessive vibration due to slight shaking.

[0040] The damper 103 can be configured as a friction damper, which can suppress small vibrations through friction. When encountering large vibrations that cause friction to fail, the lamp body assembly 200 can rotate.

[0042] An embodiment of this utility model also provides an automobile, including the headlight module of any of the above embodiments.
