Abstract
Description
Technical Field
[0001] The invention relates to the technical field of electric vehicle lighting equipment, and in particular to an electric vehicle headlamp. Background Art
[0002] With the increasing popularity of electric vehicles, night driving safety has become a focus of attention. The design of traditional electric vehicle headlights mainly focuses on providing lighting for the road ahead, but the lighting for the sides and surrounding environment is insufficient, which to some extent affects the safety of electric vehicles driving at night. Specifically, when an electric vehicle approaches other vehicles, pedestrians or obstacles, due to the strong light from traditional headlights, the difference between the front and side brightness of the electric vehicle is too large, which may cause the other driver to lose visibility of the area around the electric vehicle, and fail to remind oncoming vehicles that there are other road users near the electric vehicle, increasing the risk of accidents when meeting oncoming vehicles.
[0003] Some solutions currently available on the market include adding additional auxiliary lamps, such as turn signals and body marker lights, but these solutions often require additional space for installation and cannot dynamically adjust the lighting range according to actual driving conditions. In addition, the body marker lights can only indicate the width of the lamp body itself, rather than forming a certain safety warning area around the electric vehicle. Therefore, it is particularly important to develop an electric vehicle headlight system that can effectively enhance the side warning effect and reduce the glare problem of oncoming vehicles. Summary of the invention

[0018] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.
[0019] It should be noted that in the drawings, the size and relative size of the elements may be exaggerated for the purpose of clarity and / or description. Thus, the size and relative size of each element are not necessarily limited to the size and relative size shown in the drawings. In the specification and drawings, the same or similar reference numerals indicate the same or similar parts.
[0020] An embodiment of the present invention provides an electric vehicle headlamp, see Figure 1-3 , including a lamp body 1 capable of emitting light, and side lighting components 2 arranged on both sides of the lamp body 1, the lamp body 1 irradiates the front of the vehicle body to provide lighting, and the side lighting components 2 irradiate the sides to provide lateral lighting.
[0021] The side lighting assembly 2 includes a lamp bead 21 fixed to the outer edge of the lamp body 1, and a connecting plate 22 connected to the outer side of the lamp body 1. The connecting plate 22 is provided with a through hole 221 for allowing the light from the lamp bead 21 to pass through. A folding plate 23 is provided outside the connecting plate 22. The folding plate 23 includes a connecting section 231 that is perpendicular to the plate body of the connecting plate 22, and a reflecting section 232 that is bent from the connecting section 231 to the top of the through hole 221. The light emitted by the lamp bead 21 is reflected by the reflecting section 232 and irradiates to both sides of the lamp body 1 and forms a light spot on the side or lower side of the lamp body 1.
[0022] According to an embodiment of the present invention, the front end of the lamp body 1 has a cylindrical portion 11, and two limiting rings 12 are arranged in parallel around the outer side of the cylindrical portion 11; a plurality of recessed holes 13 are evenly and equidistantly provided on the outer wall surface of the cylindrical portion 11, and a lamp bead 21 is arranged in each recessed hole 13; the connecting plate 22 is arc-shaped; specifically, a sliding groove 121 is provided on the inner side of the limiting ring 12, and arc-shaped convex ridges 24 slidably connected to the sliding groove 121 are arranged on both sides of the connecting plate 22; the connecting plate 22 is restricted between the two limiting rings 12 and is relatively slidably connected to the outer wall surface of the cylindrical portion 11. Preferably, the connecting plates 22 are symmetrically slidably connected to the two sides of the cylindrical portion 11.
[0023] A plurality of through holes 221 are equidistantly provided on the connecting plate 22, and a folding plate 23 is provided outside each through hole 221. The number of through holes 221 is not less than the number of lamp beads 21, and the distance between adjacent through holes 221 is equal to the distance between adjacent lamp beads 21. When the electric vehicle is running, the light emitted by the plurality of lamp beads 21 is reflected by the reflecting section 232, and forms spaced, eye-catching planar light spots on both sides of the lamp body 1 (electric vehicle). A safe distance that can indicate the outline is formed on both sides of the electric vehicle, so that when vehicles meet, the oncoming driver can judge the distance from the electric vehicle through the plurality of planar light spots, thereby improving safety. And there are other vehicles, people or obstructions very close to the electric vehicle on the side of the electric vehicle. When the electric vehicle is approaching, the light spot will fall on it instead of the ground, destroying the continuity of the spaced planar light spot on the ground and warning the oncoming vehicles; and especially when meeting with the oncoming vehicles, the side lighting assembly 2 can effectively provide light for pedestrians and the like appearing from the side and rear of the electric vehicle from the headlight 1 of the front side lamp body, forming a bright area on the rear side of the electric vehicle headlight body, reducing the brightness difference between the side and front areas of the electric vehicle, solving the problem of dark and invisible areas appearing in the rear area of the electric vehicle headlight due to glare when the oncoming vehicles are traveling towards each other and observing the road conditions, making it less likely for the oncoming vehicles to have accidents due to "ghosts" appearing near the electric vehicle, and indirectly improving the safety of the electric vehicle drivers themselves.
[0024] In the embodiment of the present invention, the angle between the connecting section 231 and the reflecting section 232 of the folding plate 23 connected to the outside of each connecting plate 22 gradually decreases from top to bottom; the angle between the connecting section 231 and the reflecting section 232 is in the range of 135°-145°. By rotating the connecting plate 22, the lamp beads 21 can be made to face different through holes 221. When the connecting plate 22 is rotated upward, the angle between the reflecting section 232 and the connecting section 231 illuminated by all the lamp beads 21 becomes larger, that is, the spacing between the light spots formed by the reflected light on the ground becomes larger, and the safety distance of the electric vehicle becomes larger, otherwise, it becomes smaller; therefore, by rotating the connecting plate 22, the reflection direction of the reflected light can be adjusted, and the distance of the light spots can be controlled, so that the driver can adjust it according to his own situation.
[0025] A frame 3 capable of completely covering all folding plates 23 is fixed to the outside of the connecting plate 22 . The frame 3 wraps all folding plates 23 with a transparent acrylic plate to achieve dustproof and waterproof properties for the reflective sections 232 of the folding plates 23 .
[0026] In addition, a focusing lens 7 is arranged in the through hole 221, and the light emitted by the lamp bead 21 passes through the focusing lens 7 and then reflects through the reflection section 232, thereby improving the brightness and conspicuity of the light spot. The focusing lens 7 in this embodiment can be made of transparent plastic or resin material, and its structure is a convex lens with a thick middle and thin edges.
[0027] In some specific embodiments, the surface of the cylindrical portion 11 is provided with a plurality of limiting holes 14 at equal intervals, and the distance between each adjacent limiting hole 14 is equal to the distance between adjacent lamp beads 21; a short plate 4 is fixedly connected to the side of the connecting plate 22, and a guide hole 41 is provided on the short plate 4, and a plug 5 is plugged and connected in the guide hole 41, and a spring 6 is provided on the outer cover of the plug 5, and the two ends of the spring 6 are respectively fixedly connected to the ends of the short plate 4 and the plug 5, and the plug 5 can be plugged and pulled in the limiting hole 14 to fix the position of the connecting plate 22. Pulling out the plug 5 can slide the connecting plate 22, and when the connecting plate 22 moves into place, the plug 5 is inserted into the limiting hole 14 close to it, thereby fixing the position of the connecting plate 22; the plug-in fixing structure can be provided at each end of the connecting plate 22 to ensure the stability of the connecting plate 22.
