Description

Technical Field

[0001] This utility model relates to the field of bicycle lamp technology, and in particular to a rotating bicycle lamp with an adjustable illumination angle. Background Technology

[0002] In cycling scenarios, bicycle lights are a key component for ensuring cycling safety at night or in low-light conditions. Their installation stability and the adaptability of the illumination angle directly affect their performance.

[0003] Most bicycle lights on the market currently use a single fixed structure, such as simply attaching to the handlebars with a clip or a single strap. This method of fixing is easily affected by bumps during riding, causing the light to rotate back and forth or loosen and shift, thus shifting the illumination position and increasing riding safety hazards. At the same time, the beam angle of existing bicycle lights is mostly designed to be fixed, making it inconvenient to adjust flexibly according to actual road conditions.

[0004] To address this, we designed a rotating bicycle light with an adjustable illumination angle. Utility Model Content

[0005] This utility model discloses a rotating bicycle light with an adjustable illumination angle, which aims to solve the technical problems of existing bicycle lights.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable-angle rotating bicycle light includes a mounting assembly and a light adjustment assembly. The mounting assembly includes two locking sleeves, both of which have bottom openings. Two locking plates are symmetrically arranged at the bottom of the locking sleeves. Rectangular insertion holes are formed on the surface of the locking plates, and rubber tightening straps are inserted into the inner walls of the rectangular insertion holes. The two locking sleeves are used to be fitted onto the surface of the bicycle's lateral handlebars, and the rubber tightening straps are used to bind and limit the longitudinal handlebars of the bicycle.

[0007] In a preferred embodiment, the surface of the rubber tightening band has two corresponding threaded holes, the inner wall of the threaded holes is threaded with a locking screw, the surface of the locking screw is threaded with a locking nut, the locking nut overlaps with the surface of the rubber tightening band, and the end of the locking screw away from the locking nut is fixedly connected with an operating knob.

[0008] In a preferred embodiment, the headlight adjustment assembly includes a support base fixedly connected between two locking sleeves. A positioning adjustment cylinder is fixedly connected to the upper surface of the support base, and an extension plate is fixedly connected to the front end of the support base. Two fixed seats are symmetrically arranged on the lower surface of the extension plate. A movable block is rotatably connected between the two fixed seats via a rotating shaft. An LED headlight is fixedly connected to the top of the movable block.

[0009] In a preferred embodiment, an adjusting screw is rotatably connected to the inner bottom wall of the positioning adjusting cylinder, an adjusting block is threadedly connected to the surface of the adjusting screw, and two symmetrically positioned guide plates are fixedly connected to the front of the adjusting block, with a movable connecting rod rotatably connected between the two guide plates.

[0010] In a preferred embodiment, two L-shaped plates are fixedly disposed on the back of the LED vehicle light, and a movable shaft is rotatably connected between the two L-shaped plates. The end of the movable connecting rod away from the guide plate is fixedly connected to the surface of the movable shaft.

[0011] In a preferred embodiment, the surface of the positioning adjustment cylinder is provided with a strip-shaped guide hole, the position of which corresponds to the guide plate, and both guide plates are slidably connected to the inner wall of the strip-shaped guide hole. The top end of the adjustment screw extends to the outside of the positioning adjustment cylinder and is fixedly connected with an adjustment knob.

[0012] As can be seen from the above, the adjustable-angle rotating bicycle light provided by this utility model has the following technical effects.

[0013] Firstly, the mounting components employ a dual-fixation design using locking sleeves and rubber tightening straps. The two locking sleeves precisely fit over the horizontal surface of the bicycle handlebars, while the rubber tightening straps securely restrain the vertical handlebars, creating a cross-fixation structure that significantly reduces the risk of the light loosening or shifting due to bumps during riding, ensuring stable illumination. The rubber tightening straps are adjusted via locking screws and nuts, maintaining a consistent level of fixation over a long period and preventing the light from shifting forward or backward during riding.

[0014] Secondly, by setting up the headlight adjustment component, turning the adjustment knob can drive the adjustment screw to rotate, causing the adjustment block to move up and down along the positioning adjustment cylinder. Then, through the movable linkage, the LED headlight is pushed and pulled to rotate around the fixed base shaft. The adjustment process is smooth and the angle is controllable, which can accurately adapt to the lighting needs of different road conditions (such as flat roads, uphill, and downhill) and avoid the light being too close or too far, affecting riding safety.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 An adjustable rotating bicycle light includes a mounting assembly 1 and a light adjustment assembly 2. The mounting assembly 1 includes two locking sleeves 101, both of which are designed as arc-shaped structures with open bottoms to fit the cylindrical profile of the bicycle handlebars for easy installation. Two locking plates 102 are symmetrically fixed to the bottom edge of each locking sleeve 101.

[0022] Each locking plate 102 has a rectangular insertion hole 103 in the middle, the diameter of which matches the width of the rubber tightening band 104. Two rubber tightening bands 104 pass through the rectangular insertion holes 103 of the locking plates 102 on both sides of the same locking sleeve 101, and the two ends of the rubber tightening bands 104 extend to the outside of the locking plates 102, forming a binding structure around the longitudinal handlebar of the bicycle. At this time, the two locking sleeves 101 are horizontally fitted on the horizontal section of the bicycle handlebar, and the rubber tightening bands 104 are longitudinally bound to the vertical section of the handlebar. The horizontal and vertical cross-fixing greatly reduces the risk of the bicycle light loosening due to riding bumps and improves the installation stability.

[0023] Each rubber tightening band 104 has threaded holes at both ends. The locking screw 105 passes through the threaded hole at one end of the rubber tightening band 104 and exits at the other end to be threadedly connected to the locking nut 106. The lower surface of the locking nut 106 is tightly overlapped with the upper surface of the rubber tightening band 104. The operating knob 107 is fixed to the top of the locking screw 105.

[0024] Rotating the control knob 107 drives the locking screw 105 to rotate, which in turn drives the locking nut 106 to move down along the screw, thereby compressing the rubber tightening band 104 and achieving a tight bond to the longitudinal handlebars. Installation and disassembly can be completed without additional tools. At the same time, the self-locking property of the threaded connection can maintain the fixing force for a long time, preventing the lights from loosening back and forth during riding.

[0025] The headlight adjustment assembly 2 is used to adjust the angle of the LED headlight 206. It includes a support base 201, the lower surface of which is fixed to the middle of the upper surface of two locking sleeves 101 by bolts to form a stable support platform. The positioning adjustment cylinder 202 is a cylindrical structure with an open top. Its lower surface is welded to the rear end of the upper surface of the support base 201, and the axis of the positioning adjustment cylinder 202 is perpendicular to the support base 201. The extension plate 203 is fixed to the front edge of the support base 201, and the extension plate 203 is on the same horizontal plane as the support base 201, extending forward to the front of the handlebars to provide installation space for the LED headlight 206.

[0026] Two fixed seats 204 are symmetrically distributed and fixed on both sides of the lower surface of the extension plate 203. The movable block 205 is a rectangular block, and its two sides are rotatably connected to the through holes of the two fixed seats 204 through the pivot. The movable block 205 can rotate up and down around the pivot. The upper surface of the LED headlight 206 is fixed to the lower surface of the movable block 205 by bolts. The lighting direction of the LED headlight 206 is facing the front of the handlebars. The rotation of the movable block 205 can directly drive the LED headlight 206 to rotate synchronously, providing a basis for angle adjustment.

[0027] The bottom end of the adjusting screw 208 is rotatably connected to the center of the inner bottom wall of the positioning adjusting cylinder 202 via a bearing. The top end of the adjusting screw 208 passes through the top opening of the positioning adjusting cylinder 202 and extends out of the cylinder body. The adjusting block 209 is a cylindrical block with a threaded hole in its middle that is adapted to the adjusting screw 208. The adjusting block 209 is sleeved on the surface of the adjusting screw 208 through the threaded hole.

[0028] Two guide plates 210 are welded to the center of the front of the adjusting block 209, and the guide plates 210 extend forward to the outside of the positioning adjusting cylinder 202; a strip-shaped guide hole 214 is provided in the center of the front of the positioning adjusting cylinder 202, and the two guide plates 210 pass through the two sides of the strip-shaped guide hole 214 respectively. The strip-shaped guide hole 214 can limit the movement direction of the guide plates 210 and improve the stability of the angle adjustment.

[0029] Two L-shaped plates 212 are symmetrically fixed on both sides of the middle of the back of the LED vehicle light 206. The movable shaft 213 is rotatably connected between the two L-shaped plates 212. The bottom end of the movable connecting rod 211 is rotatably connected between the two guide plates 210 through a bearing, and the top end is fixed in the middle of the movable shaft 213. When the guide plate 210 moves up and down with the adjusting block 209, the movable connecting rod 211 can rotate around the bottom end and push and pull the movable shaft 213, thereby driving the LED vehicle light 206 to rotate up and down around the rotating shaft of the fixed seat 204 to achieve the adjustment of the illumination angle.

[0030] The adjustment knob 215 is a circular plastic knob, with its lower surface fixed to the top of the adjustment screw 208. By rotating the adjustment knob 215, the adjustment screw 208 can be driven to rotate synchronously, thereby controlling the lifting and lowering direction of the adjustment block 209, and ultimately realizing the angle adjustment of the LED vehicle light 206. When the adjustment knob 215 is rotated clockwise, the adjustment block 209 rises, and the movable connecting rod 211 pushes the front end of the LED vehicle light 206 upward, raising the illumination angle (suitable for downhill road conditions); when the adjustment knob 215 is rotated counterclockwise, the adjustment block 209 falls, and the movable connecting rod 211 pulls the front end of the LED vehicle light 206 downward, lowering the illumination angle (suitable for uphill road conditions). The adjustment process is smooth and the angle is controllable.

[0031] Working principle: When installing the bicycle light structure, place the two locking sleeves 101 on the appropriate positions of the bicycle handlebars, ensuring that the support base 201 and the extension plate 203 face the front of the handlebars; pass the two rubber tightening straps 104 through the rectangular insertion holes 103 of the locking plates 102 on both sides of the same locking sleeve 101, wrap them around the longitudinal handlebars, insert the locking screw 105 into the threaded hole of the rubber tightening strap 104 and tighten the locking nut 106; manually rotate the operating knob 107 to drive the locking screw 105 to rotate, causing the locking nut 106 to move down and compress the rubber tightening strap 104 until the rubber tightening strap 104 fits tightly against the longitudinal handlebars, completing the double fixation of the bicycle light.
