Description

Technical Field

[0001] This utility model relates to the field of electric vehicle lighting technology, and in particular to an electric vehicle headlight that is easy to adjust the beam height. Background Technology

[0002] Electric bicycles are a type of personal transportation that combines traditional bicycles with electric-assisted technology. They are environmentally friendly, convenient, and economical. As an environmentally friendly mode of transportation, electric bicycles are becoming increasingly popular in urban traffic. The headlights of electric bicycles are crucial for the safety of riding them at night.

[0003] Traditional electric vehicle headlights are mostly fixed in place, making it impossible to adjust the beam according to actual road conditions. This can easily cause glare to oncoming vehicles or insufficient illumination for the vehicle itself. Although some vehicles are equipped with manual adjustment mechanisms, these require the vehicle to be stopped, which is inconvenient.

[0004] Therefore, to address the above issues, an electric vehicle headlight with adjustable beam height can be designed. Through electric control, the beam height of the electric vehicle headlight can be adjusted during riding, providing timely and quick adjustments to adapt to different road conditions. Utility Model Content

[0005] To overcome the problem that traditional electric vehicle headlights are mostly fixed and cannot be adjusted according to actual road conditions, which can easily cause glare to oncoming vehicles or insufficient lighting for the vehicle itself, some vehicles are currently equipped with manual adjustment mechanisms, but these require the vehicle to be stopped, making them inconvenient to use.

[0006] The technical solution of this utility model is as follows: an electric vehicle headlight that facilitates adjustment of light height, comprising a lamp housing, a lamp body, a reflector, and a micro motor. A partition is fixedly installed inside the lamp housing, and two sets of first mounting seats are symmetrically fixedly installed on the upper end of the partition. The lamp body passes through the partition through a notch on the surface of the partition and is rotatably connected to the first mounting seats. Two sets of second mounting seats are symmetrically fixedly installed inside the lamp housing, and the reflector is rotatably connected between the two sets of second mounting seats. The light-emitting end of the lamp body is located inside the reflector. The micro motor is fixedly installed on the upper end of the partition, and a lead screw is fixedly installed on the output end of the micro motor. The lead screw is rotatably connected to the lamp housing, and an internally threaded rack is threadedly connected to the outer periphery of the lead screw. A residual gear is fixedly installed on the rear side of the reflector, and the residual gear meshes with the internally threaded rack.

[0007] Preferably, the interior of the lamp housing is divided by a partition, and the lamp body, together with the reflector, can illuminate the front of the lamp housing. The lamp body and the reflector can be rotatably connected to the interior of the lamp housing by the first mounting base and the second mounting base. The screw driven by the micro motor can drive the internal thread rack to move up and down, thereby driving the residual gear to rotate and adjusting the angle of the reflector, thus adjusting the height of the emitted light and ensuring good lighting for riding electric vehicles at night.

[0008] Preferably, a base plate is fixedly installed on the upper end of the lamp body, and multiple sets of heat dissipation fins are fixedly installed on the upper end of the base plate.

[0009] Preferably, multiple ventilation holes are provided on both sides of the lamp housing, and the ventilation holes are located at the upper end of the partition.

[0010] Preferably, the lamp housing has a plug-in portion on its outer periphery, and a transparent lampshade is provided on the front side of the lamp housing. The transparent lampshade is connected to the lamp housing by the plug-in portion.

[0011] Preferably, two sets of guide plates are fixedly installed inside the lamp housing. The guide plates are located below the partition, and the internal threaded rack is slidably connected between the two sets of guide plates.

[0012] Preferably, a flexible rubber sheet is fixedly installed inside the notch on the surface of the partition, and the flexible rubber sheet is fitted around the outside of the lamp body.

[0013] Preferably, multiple sets of wire holes are provided on the rear side of the lamp housing, and a fixing sleeve is fixedly installed inside the wire holes.

[0014] The beneficial effects of this utility model are:

[0015] The lamp body, in conjunction with the reflector, illuminates the front of the lamp housing. A micro motor drives a lead screw to rotate, causing an internal threaded rack to rise and slide. A guide plate guides the internal threaded rack to move stably, which in turn drives a residual gear to rotate. This, in turn, causes the reflector to rotate inside the second mounting bracket. The lamp body, inside the first mounting bracket, follows the reflector's rotation, allowing for adjustment of the reflector's angle. This enables riders to adjust the height of the emitted light during riding, adapting to different road conditions and ensuring good illumination for nighttime electric vehicle riding.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 3 and Figure 4 This utility model provides an embodiment of an electric vehicle headlight with adjustable beam height, comprising a lamp housing 1, a lamp body 2, a reflector 3, and a micro motor 4. A partition 101 is fixedly installed inside the lamp housing 1. Two sets of first mounting seats 201 are symmetrically fixedly installed on the upper end of the partition 101. The lamp body 2 passes through a notch on the surface of the partition 101 and is rotatably connected to the first mounting seats 201. Two sets of second mounting seats 301 are symmetrically fixedly installed inside the lamp housing 1. The reflector 3 is rotatably connected between the two sets of second mounting seats 301. The light-emitting end of the lamp body 2 is located inside the reflector 3. The micro motor 4 is fixedly installed on the upper end of the partition 101. A lead screw 401 is fixedly installed on the output end of the micro motor 4 and is rotatably connected to the lamp housing 1. The lead screw 401 is threadedly connected to an internally threaded rack 402. A residual gear 302 is fixedly installed on the rear side of the reflector bowl 3, and the residual gear 302 meshes with the internally threaded rack 402. The interior of the lamp housing 1 is divided by a partition 101. The lamp body 2, in conjunction with the reflector bowl 3, can illuminate the front of the lamp housing 1. The lamp body 2 and the reflector bowl 3 can be rotatably connected to the interior of the lamp housing 1 by a first mounting base 201 and a second mounting base 301. The lead screw 401 is driven to rotate by a micro motor 4, which can drive the internally threaded rack 402 to rise and slide. The internally threaded rack 402 pushes the residual gear 302 to rotate, which can adjust the angle of the reflector bowl 3, thereby adjusting the height of the emitted light and ensuring good lighting for riding electric vehicles at night.

[0023] Please see Figure 1 and Figure 2 In this embodiment, a base plate 202 is fixedly installed on the upper end of the lamp body 2, and multiple sets of heat dissipation fins 203 are fixedly installed on the upper end of the base plate 202. By setting the base plate 202, the heat generated by the lamp body 2 during operation can be absorbed, and the heat dissipation area can be increased and the heat dissipation efficiency can be improved by increasing the heat dissipation area through the heat dissipation fins 203. Multiple sets of ventilation holes 102 are opened on both sides of the lamp housing 1, and the ventilation holes 102 are located at the upper end of the partition plate 101. By setting the ventilation holes 102, the heat discharged by the micro motor 4 and the heat dissipation fins 203 above the partition plate 101 can be discharged from the lamp housing 1 in a timely manner. A plug-in part 103 is opened on the periphery of the lamp housing 1, and a transparent lamp cover 104 is provided on the front side of the lamp housing 1. The transparent lamp cover 104 is connected to the lamp housing 1 through the plug-in part 103. The plug-in part 103 is used to connect and fix the transparent lamp cover 104 to the lamp housing 1, and the transparent lamp cover 104 is used to shield and protect the inside of the lamp housing 1.

[0024] Please see Figure 2 and Figure 4 In this embodiment, two sets of guide plates 403 are fixedly installed inside the lamp housing 1. The guide plates 403 are located below the partition 101, and the internal threaded rack 402 is slidably connected between the two sets of guide plates 403. By setting the guide plates 403, the lifting and sliding of the internal threaded gear can be guided, making its movement stable. A flexible rubber sheet 5 is fixedly installed inside the notch on the surface of the partition 101. The flexible rubber sheet 5 is sleeved on the periphery of the lamp body 2. By setting the flexible rubber sheet 5, the notch on the surface of the partition 101 can be blocked without affecting the rotation of the lamp body 2 following the reflector bowl 3, preventing the upper and lower spaces of the partition 101 from affecting each other. Multiple sets of wire holes 6 are opened on the rear side of the lamp housing 1. A fixing sleeve 601 is fixedly installed inside the wire holes 6. By setting the wire holes 6, it is convenient for the lamp body 2 and the micro motor 4 to be connected to the outside of the lamp housing 1. By setting the fixing sleeve 601, the connected wires can be stably covered to prevent the connected wires from becoming loose.

[0025] When in operation, the lamp body 2, in conjunction with the reflector bowl 3, can emit light to illuminate the front of the lamp housing 1. The micro motor 4 drives the lead screw 401 to rotate, which in turn drives the internal thread rack 402 to rise and slide. The guide plate 403 guides the rising and falling of the internal thread rack 402, allowing it to rise and fall stably. The internal thread rack 402 then drives the residual gear 302 to rotate, which in turn drives the reflector bowl 3 to rotate inside the second mounting base 301. The lamp body 2 will follow the reflector bowl 3 to rotate inside the first mounting base 201, thereby adjusting the angle of the reflector bowl 3 and adjusting the height of the emitted light to ensure good lighting for riding electric vehicles at night.

[0026] The substrate 202 can absorb the heat generated by the lamp body 2 during operation, and the heat dissipation fins 203 can increase the heat dissipation area and improve the heat dissipation efficiency. The partition 101 is used to separate the inside of the lamp housing 1, reducing the impact of the heat generated by the heat dissipation fins 203 and the micro motor 4 on the reflector bowl 3 below. The ventilation hole 102 can promptly dissipate the heat above the partition 101. Due to the obstruction of the partition 101, a small amount of dust entering the inside of the lamp housing 1 through the ventilation hole 102 will not be adsorbed on the surface of the reflector bowl 3, ensuring good light output.

[0027] Through the above steps, the internal threaded rack 402 drives the residual gear 302 to rotate, which can adjust the angle of the reflector bowl 3, thereby adjusting the height of the emitted light. The height of the lighting can be adjusted during riding to adapt to different road conditions and ensure good lighting for electric vehicles at night. This solves the problem that traditional electric vehicle headlights are mostly fixed and cannot be adjusted according to actual road conditions, which can easily cause glare to oncoming vehicles or insufficient lighting for the vehicle itself. Although some vehicles are equipped with manual adjustment mechanisms, they require stopping to operate, which is inconvenient.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
