Description

Technical Field

[0001] This utility model relates to the field of headlight technology, specifically to a height-adjustable headlight for a three-wheeled electric vehicle. Background Technology

[0002] During vehicle manufacturing, the headlight height must be rigorously adjusted to meet compliance requirements. However, this adjustment process is time-consuming, directly increasing labor costs in the production process and impacting overall production efficiency. Meanwhile, users must navigate complex and varied road conditions while driving—whether it's the ramps and inclines of urban roads or the winding mountain roads of the suburbs, the vehicle's driving posture changes significantly. Furthermore, different drivers have varying visual needs regarding headlight height due to differences in height and seating habits. However, most enclosed electric tricycles on the market currently use a fixed headlight height design, leading to numerous problems: when climbing hills, the headlights are offset upwards, resulting in insufficient illumination of the nearby road surface and affecting the driver's judgment of obstacles at close range; when descending hills, the headlights are excessively lowered, limiting visibility of distant road conditions and significantly increasing driving risks. In addition, fixed headlights cannot match the individual needs of drivers, severely reducing nighttime driving safety and passenger comfort.

[0003] Currently, a utility model patent with publication number CN223204171U discloses a headlight height adjustment mechanism for electric vehicles. It includes an adjusting screw, an adjusting mechanism rotatably mounted on the adjusting screw, and an adjusting disc connected to the lower headlight housing at one end. The adjusting mechanism includes an adjusting seat, on which a connector for connecting to the upper headlight housing is held. The adjusting disc includes a turntable with a ring-shaped rack on one side. After the upper and lower headlight housings are assembled, a hole is left on the lower housing corresponding to the position of the adjusting disc. A Phillips screwdriver is passed through the hole and engages with the rack to rotate the adjusting disc. The rotation of the adjusting disc drives the adjusting screw to rotate. The adjusting seat is rotatably connected to the adjusting screw, causing the adjusting seat to move. Since the adjusting seat is fixed to the upper headlight housing, it moves the upper headlight housing, thereby adjusting its position and achieving the effect of adjusting the headlight position. This allows users to adjust the headlight position according to their needs, improving the adaptability of the headlight.

[0004] As can be seen from the above-disclosed technical content, as existing technology, the utility model with announcement number CN223204171U allows the adjustment disc to be rotated by passing a Phillips screwdriver through a hole and engaging with a rack. The rotation of the adjustment disc drives the adjustment screw to rotate, and the adjustment seat is connected to the adjustment screw, causing the adjustment seat to move. Since the adjustment seat is fixed to the headlight upper shell, it drives the headlight upper shell to move, thereby adjusting the position of the headlight upper shell. However, this patent requires the intervention of a worker with a screwdriver during adjustment, which is not very convenient to use, especially when driving, making it difficult to operate.

[0013] The adjustable headlight of this utility model for a three-wheeled electric vehicle is described below with reference to the accompanying drawings.

[0014] In Embodiment 1 of this application, as Figures 1 to 3 As shown, the height-adjustable headlight of this three-wheeled electric vehicle (hereinafter referred to as "the present invention") includes a headlight front shell 1 and a headlight rear shell 5. Two trunnion brackets 51 are symmetrically installed in the headlight adjustment cavity 4 of the headlight rear shell 5. Height-adjusting trunnions 31 are fixedly installed on both sides of the lamp bead fixing bracket 32 ​​of the headlight body 3. The trunnion brackets 51 are movably sleeved with the height-adjusting trunnions 31. A rotatable control screw 6 is installed in the opening of the headlight rear shell 5. The threaded end of the control screw 6 is screwed to the adjusting nut 36 movably installed under the lamp bead fixing bracket 32 ​​through the bracket. The adjusting nut 36 is movably installed in the through hole reserved on the lower bracket of the lamp bead fixing bracket 32 ​​through the side pivot or rubber sleeve. A lamp bead circuit board 34 is fixedly installed on the lamp bead fixing bracket 32. A lens 2 is set at the front of the lamp bead circuit board 34. Lamp beads 35 are installed on the side of the lamp bead circuit board 34 facing the lens 2. The front of the headlight rear shell 5 is closed by the headlight front shell 1. The outer end of the control screw 6 is fixedly connected to a universal joint. The universal joint is connected to a knob in the cab through a pivot.

[0015] The utility model patent CN223204171U discloses a headlight height adjustment mechanism for electric vehicles (hereinafter referred to as "the patent"). A Phillips screwdriver, inserted through a hole and engaged with a rack, rotates an adjustment disc. The rotation of the disc drives an adjustment screw, which is connected to an adjustment seat. This allows the adjustment seat to move the adjustment screw, and since the adjustment seat is fixed to the headlight housing, it moves the headlight housing, thus adjusting its position. However, this patent requires a worker to use a screwdriver for adjustment, making it inconvenient, especially while driving. In contrast, this invention allows direct adjustment of the headlight height from inside the driver's cab by rotating a knob, which drives a shaft and universal joint, operating a control screw 6. The thread of the control screw 6 drives an adjustment nut 36, and the bracket of the adjustment nut 36 causes the headlight body 3 to rise and fall around a height adjustment trunnion 31. This allows for simple and convenient direct adjustment of the headlight height from inside the driver's cab.

[0016] To further optimize the working efficiency of this application and enable the control screw 6 to be locked when not in use, a control screw locking gear 61 is fixedly installed at one end of the control screw 6 located on the outside of the headlight rear housing 5. The spring locking mechanism 7 of the headlight rear housing 5 engages with the control screw locking gear 61. The tooth sides of the control screw locking gear 61 are gently sloping, and the locking pin of the spring locking mechanism 7 is attached to the tooth surface of the control screw locking gear 61. When the control screw locking gear 61 rotates, the teeth can push up the locking pin, allowing the control screw 6 to rotate smoothly. When the control screw 6 is not rotating, the locking pin is pressed against the two teeth of the control screw locking gear 61 under the action of the spring, achieving the locking purpose. To ensure the stable operation of the headlight for a long time, a circuit board heat sink 33 is fixedly installed at the rear of the lamp bead fixing bracket 32. For waterproofing, a rubber sealing ring is provided between the control screw 6 and the headlight rear housing 5. The headlight front housing 1 is made of tempered glass.

[0017] When in use, simply install the height-adjustable headlights on the three-wheeled electric vehicle and connect the corresponding wiring equipment to put it into operation.

[0018] When this utility model is used, its specific operation is as follows: In use, the driver directly turns the knob in the cab, which drives the rotating shaft and universal joint to operate the control screw 6. The thread of the control screw 6 drives the adjusting nut 36, and the bracket of the adjusting nut 36 drives the headlight body 3 to tilt around the height adjusting trunnion 31 in the trunnion bracket 51 of the headlight rear housing 5, thereby raising and lowering the light path height. The headlight height can be easily and conveniently adjusted directly in the cab.

[0019] The adjusting nut 36 is connected to the bracket or control plate at the lower part of the lamp bead fixing bracket 32 ​​via rotating shafts or rubber sleeves on both sides. When the adjusting nut 36 is connected to the bracket or control plate at the lower part of the lamp bead fixing bracket 32 ​​via rotating shafts on both sides, a gap is reserved between the rotating shaft and the bracket or control plate so that the adjusting nut 36 will not be jammed when the control screw 6 is operated. When the adjusting nut 36 is connected to the lamp bead fixing bracket 32 ​​via rubber sleeves, it can be ensured that the adjusting nut 36 and the bracket or control plate at the lower part of the lamp bead fixing bracket 32 ​​are flexibly connected when the adjusting nut 36 moves back and forth, with sufficient play to ensure smooth control. When the adjusting nut 36 moves back and forth under the action of the control screw 6, it can drive the headlight body 3 to pitch around the height adjusting trunnion 31 in the trunnion bracket 51 of the headlight rear shell 5.

[0020] In summary, the height-adjustable headlight of the three-wheeled electric vehicle in this embodiment of the utility model allows for easy and convenient adjustment of the headlight height directly from inside the driver's cab by rotating a knob in the cab. This knob drives the rotating shaft and universal joint, which in turn operates the control screw 6. The thread of the control screw 6 drives the adjusting nut 36, and the bracket of the adjusting nut 36 drives the headlight body 3 to rise and fall around the height-adjusting trunnion 31.
