Description

Technical Field

[0001] This utility model relates to a motorcycle headlight assembly technology, and more particularly to an adjustable motorcycle headlight assembly. Background Technology

[0002] Motorcycle headlights are primarily used for nighttime road illumination and are typically mounted at the front of the motorcycle's steering column. They illuminate the road ahead and the surrounding environment when driving at night. Current motorcycle headlight assemblies are usually fixed installations, meaning the tilt angle and illumination distance are not adjustable once installed. Regardless of whether the motorcycle is traveling on flat grasslands or plains, or on rugged mountain roads, the headlight's illumination distance remains the same. However, the lighting requirements differ depending on whether the motorcycle is on a flat or rugged road. On flat roads, the headlights can be positioned slightly further to provide a wider field of vision, allowing for earlier observation of road conditions and timely action. On rugged roads, with their numerous curves, the headlights should be positioned slightly closer to allow for timely observation of curves and better control of the motorcycle's direction.

[0003] Clearly, existing motorcycle headlight assemblies suffer from problems such as the headlight illumination distance not being adjustable, which is not conducive to driving at night under different road conditions. Summary of the Invention

[0004] To address the problems of existing motorcycle headlight assemblies having non-adjustable headlight illumination distance, which is detrimental to nighttime driving under different road conditions, this utility model proposes an adjustable motorcycle headlight assembly.

[0005] This utility model relates to an adjustable headlight assembly for motorcycles, comprising an outer shell, a bottom shell, an inner liner, a lamp body, a lamp holder, a movable base plate, a movable connecting mechanism, and an adjustment mechanism. The outer shell and bottom shell, when snapped together, form the external structure of the headlight. The inner liner, lamp body, lamp holder, movable base plate, movable connecting mechanism, and adjustment mechanism are all installed within the cavity formed by the snapped outer shell and bottom shell. The movable base plate is movably mounted on the front surface of the bottom shell via the movable connecting mechanism and the adjustment mechanism. The lamp holder, lamp body, and inner liner are sequentially fixedly mounted on the movable base plate.

[0006] Furthermore, the movable base plate is movably mounted on the front surface of the bottom shell via a movable connecting mechanism and an adjusting mechanism. This includes: circular through holes on both sides of the upper part of the movable base plate, and a rectangular through hole in the middle of the lower part of the movable base plate; the movable connecting mechanism is a ball-head connecting mechanism, including ball-head bolts and ball caps; there are two ball-head bolts, one end of which is screwed and fixed to the bottom shell, and the other end has a sphere; the ball caps are two semi-circular spherical structures, with a spherical cavity inside the semi-circular sphere, the size of which matches the sphere of the ball-head bolt, and a through gap in the radial direction of the semi-circular sphere; during installation, the two ball-head bolts are screwed onto the upper middle sides of the inner surface of the bottom shell, the movable base plate is fitted onto the ball-head bolts through the circular through holes on both sides of the upper middle part, and the two ball caps are pressed onto the spheres, thereby restricting the axial and vertical / left / right movement of the movable base plate while allowing it to rotate relative to the ball head; the adjusting mechanism includes an adjusting bolt, an adjusting seat, a retaining ring, and an adjusting disc; the front section of the adjusting bolt screw is provided with... The adjusting seat has an external thread, an annular groove in the middle and rear section, and a hexagonal bolt head at the rear end. The adjusting seat is a cubic structure with a clamp with a V-shaped opening at the front end, a cylindrical notch on the outside of the clamp, and a rectangular baffle behind the cylindrical notch. Furthermore, the cubic adjusting seat has an internal thread in its longitudinal direction that matches the external thread of the adjusting bolt. The retaining ring is a hollow disc structure, its inner hole size matching the annular groove in the middle and rear section of the adjusting bolt. The adjusting disc is hollow. The adjusting disc has an inner hole whose size and shape match the head of the adjusting bolt. During installation, the adjusting bolt's screw passes outward through the through hole in the middle of the lower part of the base shell. A retaining ring is fitted onto the screw from one side and engages in a groove in the middle and rear section of the screw, thereby restricting the axial movement of the screw relative to the base shell while allowing it to rotate. The cylindrical notch of the adjusting seat is vertically fitted into the rectangular through hole in the middle of the lower part of the movable base plate. At the same time, the internal thread of the adjusting seat is screwed onto the adjusting screw. The adjusting disc is fitted onto the head of the adjusting bolt.

[0007] Furthermore, the ball head bolt is also provided with a locking nut, which is screwed onto the threaded rod of the ball head bolt.

[0017] The adjustable headlight assembly for motorcycles of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0018] From the appendix Figure 1 , 2 As can be seen from sections 3 and 4, the adjustable headlight assembly for motorcycles of this utility model includes an outer shell 1, a bottom shell 2, an inner liner 3, a lamp body 4, a lamp holder 5, a movable base plate 6, a movable connecting mechanism 7, and an adjustment mechanism 8. The outer shell and bottom shell, when fastened together, form the external structure of the headlight. The inner liner, lamp body, lamp holder, movable base plate, movable connecting mechanism, and adjustment mechanism are installed within the cavity formed by the fastened outer shell and bottom shell. The movable base plate is movably mounted on the front surface of the bottom shell via the movable connecting mechanism and the adjustment mechanism. The lamp holder, lamp body, and inner liner are sequentially fixedly mounted on the movable base plate. With the lamp holder, lamp body, and inner liner sequentially fixedly mounted on the movable base plate, the illumination distance of the headlight can be adjusted by adjusting the movable base plate, allowing the motorcycle headlight to better adapt to different road conditions.

[0019] From the appendix Figure 4 , 5As can be seen from section 6, as one of the preferred technical solutions, the movable base plate is movably mounted on the front surface of the bottom shell through a movable connecting mechanism and an adjusting mechanism. This includes having circular through holes on both sides of the upper part of the movable base plate and a rectangular through hole in the middle of the lower part of the movable base plate. The movable connecting mechanism is a ball-head connecting mechanism, including a ball-head bolt 7-1 and a ball cap 7-2. There are two ball-head bolts, one end of which is screwed and fixed to the bottom shell, and the other end has a ball. There are two ball caps, each a semi-circular sphere, located inside the semi-circular sphere. The device features a spherical cavity whose size matches the sphere of the ball-head bolt. A through-hole is provided radially within the semi-circular sphere. During installation, two ball-head bolts are screwed onto the upper middle sides of the inner surface of the bottom shell. The movable plate is fitted onto the ball-head bolts through the circular through-holes on both sides of the upper middle section. Two ball caps are pressed onto the sphere, thereby restricting the axial, vertical, left-right, and vertical movement of the movable plate while allowing it to rotate relative to the ball head. The adjustment mechanism includes an adjusting bolt 8-1, an adjusting seat 8-2, a retaining ring 8-3, and an adjusting disc 8- 4; The adjusting bolt has an external thread at the front, an annular groove at the middle and rear, and a hexagonal bolt head at the rear; The adjusting seat is a cubic structure, with a clamp with a V-shaped opening at the front end, a cylindrical notch on the outside of the clamp, and a rectangular baffle behind the cylindrical notch; Furthermore, the cubic adjusting seat has an internal thread that matches the external thread of the adjusting bolt in the longitudinal direction; The retaining ring is a hollow disc structure, and its inner hole size matches the annular groove at the middle and rear of the adjusting bolt. The adjusting disc is a hollow disc structure, and the size and shape of its inner hole match the bolt head of the adjusting bolt. During installation, the screw of the adjusting bolt passes outward through the through hole in the middle of the lower part of the bottom shell. The retaining ring is fitted onto the screw from one side and engages in the groove in the middle and rear section of the screw, thereby restricting the axial movement of the screw relative to the bottom shell while allowing it to rotate. The cylindrical notch of the adjusting seat is vertically engaged in the rectangular through hole in the middle of the lower part of the movable base plate. At the same time, the internal thread of the adjusting seat is screwed onto the adjusting screw. The adjusting disc is fitted onto the bolt head of the adjusting bolt. Because a ball joint connection mechanism is used to connect the movable base plate to the bottom shell, that is, a ball cap is used to install the movable base plate on the ball of the ball head bolt, while ensuring that the movable base plate cannot move axially, vertically, horizontally, or vertically, it can also rotate relative to the ball head bolt, thereby changing the tilt angle of the headlight and adjusting the illumination distance of the headlight. The adjusting mechanism uses an adjusting seat engaged in the rectangular through hole in the middle of the lower part of the movable base plate, which ensures that the lower part of the movable base plate cannot move vertically, horizontally, or vertically, while allowing for slight left and right rotation. Since the adjusting bolt is rotatably fixed to the bottom shell, when the adjusting plate rotates, the rotation of the adjusting bolt will drive the adjusting seat to move axially along the adjusting bolt, and the movable base plate clamped on the adjusting seat will also rotate relative to the ball head bolt, thereby adjusting the tilt angle of the headlight, that is, adjusting the illumination distance of the headlight.The slight left and right rotation of the movable base plate can prevent interference when the movable base plate rotates relative to the ball head bolt.

[0020] As one of the preferred technical solutions, the ball head bolt is further provided with a locking nut 7-3, which is screwed onto the threaded rod of the ball head bolt (see Appendix). Figure 4 , 5 When the ball head bolt is screwed to the set height, the lock nut can be tightened downwards to lock the ball head bolt, thus preventing it from rotating freely due to bumps and vibrations during motorcycle operation, which could cause the movable base plate to loosen.

[0021] As one of the preferred technical solutions, the adjusting disc is further provided with a stop tooth, which is located axially on the outer circle of the adjusting disc and points towards the bottom surface of the bottom shell (see Appendix). Figure 4 , 6 Setting a stop tooth on the adjustment disc can prevent the brake disc from rotating randomly due to bumps and vibrations during motorcycle operation, thus preventing the headlight's illumination distance from changing erratically.

[0022] Obviously, the beneficial technical effect of this utility model of adjustable headlight assembly for motorcycles is that it can conveniently adjust the illumination distance of the headlight, so that the motorcycle headlight can better adapt to different road conditions.
