Description

Technical Field

[0001] This utility model relates to the field of electric bicycle technology, and in particular to a light fixing device for an electric bicycle. Background Technology

[0002] Electric bicycles are a type of green and environmentally friendly transportation tool that is primarily powered by electricity and supplemented by human riding. They combine the advantages of traditional bicycles and electric motors, allowing riders to pedal or use a battery-powered motor for power, thus saving effort and increasing speed.

[0003] Currently, although electric bicycles are generally equipped with basic lighting systems when they leave the factory, their brightness is low and their illumination range is limited, making it difficult to meet the safety riding needs at night or in bad weather. Users often need to install additional high-brightness external lights to improve the lighting effect. However, the existing methods of fixing external lights usually use simple clamps, adhesive patches or single-point screws, which have problems such as inconvenient installation, loose structure, and poor shock resistance. They cannot adapt to the installation environment of different models, and the disassembly and assembly process is cumbersome and not conducive to daily maintenance.

[0004] To address the aforementioned issues, a device for fixing the headlights of electric bicycles is needed. Utility Model Content

[0005] To overcome the shortcomings of vehicle lights not being able to adapt to the installation environment of different vehicle models, this utility model provides a vehicle light fixing device for electric bicycles.

[0006] The technical solution of this utility model is as follows: a light fixing device for an electric bicycle, comprising a mounting frame, a lead rod, a guide rod, a fixing plate, a docking plate, a mounting plate, fixing screws, and a light. The mounting frame has symmetrical docking grooves on the left and right sides inside. The lead rod is threadedly connected to the bottom left side of the mounting frame, and the guide rod is slidably connected to the bottom right side of the mounting frame. The top of the lead rod is rotatably connected to the fixing plate, and the top of the guide rod is connected to the fixing plate. The docking plates are engaged inside the two docking grooves. The mounting plate is provided at the bottom of the mounting frame, and three fixing screws are provided on the mounting plate. All three fixing screws are threaded with the mounting frame. The light is installed at the bottom of the mounting plate.

[0007] As an improvement to the above solution, it also includes a pin. The top of the mounting frame is symmetrically provided with first fixing grooves on the left and right sides, and the top of the docking plate is symmetrically provided with second fixing grooves on the left and right sides. Pins are engaged between the two first fixing grooves and the two second fixing grooves at the same position.

[0008] As an improvement to the above solution, a pull ring is also included, with a pull ring attached to the top of each pin.

[0009] As an improvement to the above solution, a connecting rod is also included, with the bottom of the lead screw connected to the connecting rod.

[0010] As an improvement to the above solution, the bottom of the docking plate is provided with multiple semi-circular grooves.

[0011] As an improvement to the above solution, the bottom of the fixing plate is provided with multiple semi-circular grooves.

[0012] The beneficial effects of this utility model are as follows: The mounting frame can be directly inserted into the front basket crossbeam from the rear. With the side-inserted docking plate and the pin locking structure, quick positioning and pre-fixation can be achieved. The main assembly can be completed without complicated tools. The lifting and adjusting mechanism of the screw and guide rod linkage drives the fixing plate to move upward, so that the bottom arc groove and the bottom semi-circular groove of the docking plate clamp the horizontal support rod of the front basket, forming a double-point clamping structure, which greatly enhances the overall rigidity and impact resistance of the device and ensures stable operation under bumpy road conditions. At the same time, the structural design fully considers the differences in the size of the front basket and the crossbeam layout of different electric bicycles. The opening width of the mounting frame, the insertion depth of the docking plate, and the adjustment stroke of the clamping mechanism can all be adapted to the installation space of various common models. It effectively solves the problem that traditional external vehicle lights cannot adapt to different vehicle installation environments due to fixed structure and poor compatibility, and significantly improves the versatility and applicability of the device.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0018] Example: A light mounting device for an electric bicycle, such as... Figures 1-3As shown, the system includes a mounting frame 1, a lead screw 3, a guide rod 4, a fixing plate 5, a docking plate 6, a mounting plate 7, a fixing screw 8, a headlight 9, a pin 12, a pull ring 13, and a connecting rod 14. The mounting frame 1 has symmetrical docking grooves 2 inside, used for inserting and limiting the docking plate 6 from the side, achieving lateral fixation and preventing it from sliding left and right. The lead screw 3 is threaded to the bottom left side of the mounting frame 1, and the guide rod 4 is slidably connected to the bottom right side of the mounting frame 1. The top of the lead screw 3 is rotatably connected to the fixing plate 5, and the top of the guide rod 4 is connected to the fixing plate 5. The bottom of the fixing plate 5 has multiple semi-circular grooves for fitting with the lateral support rod of the front basket, forming an upper clamping point and participating in the double-point clamping structure. The docking plate 6 is snapped into the two docking grooves 2. The bottom of the docking plate 6 has multiple semi-circular grooves, which, together with the fixing plate 5, achieve double-layer clamping from top to bottom, enhancing overall rigidity. The bottom of the mounting frame 1... The unit is equipped with a mounting plate 7, which has three fixing screws 8. All three fixing screws 8 are threaded into the mounting frame 1. A vehicle light 9 is installed at the bottom of the mounting plate 7 to provide additional lighting brightness and illumination range for the electric bicycle, improving riding safety at night or in inclement weather. The top of the mounting frame 1 has symmetrical first fixing grooves 10, and the top of the docking plate 6 has symmetrical second fixing grooves 11. Pins 12 are engaged between the two first fixing grooves 10 and the two second fixing grooves 11 at the same position. They are inserted into the first fixing grooves 10 and the second fixing grooves 11 to axially lock the docking plate 6, preventing it from coming out of the docking grooves 2 due to vibration or impact during use, thus improving connection reliability. Each pin 12 is connected to a pull ring 13 at the top, which makes it easy for the user to manually pull out the pin, achieving quick disassembly without tools. The bottom of the lead screw 3 is connected to a connecting rod 14.

[0019] When installing the headlight 9, the operator first aligns the rear of the mounting frame 1 with the crossbeam structure of the electric bicycle's front basket and inserts it into the basket from the rear. The opening size of the mounting frame 1 matches the crossbeam of the basket to ensure initial stable positioning. Then, the connecting plate 6 is inserted laterally into the symmetrically arranged connecting slots 2 inside the mounting frame 1 to achieve lateral restraint and prevent the connecting plate 6 from loosening due to vibration or impact during use. The operator inserts two pins 12 into the first fixing slot 10 at the top of the mounting frame 1 and the corresponding second fixing slot 11 at the top of the connecting plate 6, forming a cross-locking structure. This completes the axial and lateral double fixation of the connecting plate 6, significantly improving connection reliability. Next, the semi-circular groove at the bottom of the connecting plate 6 is accurately fitted onto the lateral support rod at the bottom of the front basket, allowing the entire mounting frame 1 to achieve a rigid connection with the vehicle body through the connecting plate 6. At this point, the mounting frame 1 is initially fixed to the vehicle body structure through mechanical nesting. To further enhance the overall structural stability, the operator manually rotates the connecting plate 6. The connecting rod 14 at the bottom of the mounting frame 1 is fixedly connected to the lead screw 3 and rotates synchronously. Because the lead screw 3 is threaded to the bottom of the mounting frame 1, its rotation generates an upward axial displacement, causing the fixed plate 5, which is rotatably connected to it, to move upward. Simultaneously, the guide rod 4, acting as a guide element, slides within the mounting frame 1 to ensure smooth, unbiased movement. As the lead screw 3 continues to rotate, the fixed plate 5 gradually moves upward until the arc-shaped groove at the bottom of the fixed plate 5 tightly fits and wraps around the same or [missing information - likely a specific component or element] of the front basket. Adjacent crossbars, at this point, the mounting frame 1, the docking plate 6, the fixing plate 5, and the vehicle body crossbar form a clamping double-point fixing structure, that is, both the upper and lower layers hold the crossbar tightly through the arc groove, which greatly improves the vibration and impact resistance and effectively prevents the device from loosening or falling off under bumpy road conditions. Finally, the mounting plate 7 with the vehicle light 9 is placed at the bottom of the mounting frame 1, and three fixing screws 8 are used to fasten it to the mounting frame 1 through threads, providing uniform clamping force to ensure that the mounting plate 7 is firm and reliable. At this point, the vehicle light 9 is fully installed.
