Description

Technical Field

[0001] This application belongs to the field of electric bicycle accessories, specifically relating to a headlight panel assembly for an electric bicycle. Background Technology

[0002] Headlights are one of the most important lighting devices for electric bicycles. As a crucial safety accessory, they are typically installed at the front of the vehicle, such as on the front panel or front fork. When riding at night or in low-light conditions, headlights provide sufficient illumination for the rider to clearly see the road conditions and potential obstacles ahead, enabling them to make correct driving decisions. This is the most basic function of electric bicycle headlights. Headlights also serve a warning function; at night or in poor visibility conditions, the headlights alert other road users to the presence of the electric bicycle, thus reducing the risk of traffic accidents. The headlights help riders clearly identify their direction of travel, especially on winding roads, where they aid in better route selection. Furthermore, electric bicycle headlights enhance overall safety. For example, headlights using high-efficiency light sources such as LEDs significantly reduce energy consumption while increasing brightness and illumination distance, allowing riders to maintain clear visibility even at night or in adverse weather conditions.

[0003] However, existing electric bicycle headlights are usually exposed to the outside, making them susceptible to environmental factors such as rainwater and dust entering the headlight, which can damage the light fixture or cause circuit failures, increasing maintenance costs. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a headlight panel assembly for electric bicycles, which protects the headlight, reduces external influences, and extends the service life of the headlight.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An electric bicycle headlight panel assembly includes a front panel connected to the main body of the electric bicycle. The inner side of the front panel is connected to a slide rail body. The front of the front panel has a headlight opening positioned corresponding to the headlight. The headlight opening has an openable and closable sliding cover. The sliding cover slides along the slide rail body. One end of the sliding cover is rotatably connected to a connecting rod assembly. Both sides of the connecting rod assembly are connected to a transmission assembly. The transmission assembly is connected to the power output shaft of the motor.

[0007] Furthermore, the slide body includes two parallel folded side plates and a base plate connected to the bottom of the two side plates. The side plates have a first guide slide and a second guide slide. The second guide slide is located in the folded part of the side plate and is arranged along the length of the side plate. A guide shaft is rotatably connected inside the second guide slide. The guide shaft includes a straight rod part and a first enlarged part located at one end of the straight rod part. The end of the straight rod part away from the first enlarged part is fixedly connected to a sliding cover. The first guide slide includes a straight section and a raised section communicating with the straight section. The raised section is located at the end of the straight section and is raised upward. The base plate has an opening for installing headlights. Two parallel sliding grooves are formed on the base plate between the two first guide slides.

[0008] Furthermore, both the first guide slide and the second guide slide are through grooves set on the side plate. The inner walls of both the first guide slide and the second guide slide are provided with protrusions protruding into the slide. The protrusions are set along the first guide slide and the second guide slide. The first enlarged part of the guide shaft is set on the second guide slide outside the protrusion. The first enlarged part is used to prevent the guide shaft from falling out of the second guide slide.

[0009] Furthermore, the sliding cover includes a cover plate, two side ears fixed to the top of the cover plate and arranged opposite each other, and a connecting post fixed to the bottom of the cover plate. The connecting post has a positioning hole for fixed connection with the guide shaft, and each of the two side ears has a first through hole.

[0010] Furthermore, the linkage assembly includes a first linkage rotatably connected to one end of the sliding cover, a rotating block rotatably connected to the first linkage, a sliding block connected to the rotating block, and a plurality of second linkages penetrating the sliding block. Both ends of the first linkage are respectively disposed within a first guide slide, and each end of the first linkage has a second enlarged portion. The first linkage between the two side plates is rotatably connected to a first through hole, and the second enlarged portion is located within the first guide slide and abuts against a protrusion within the first guide slide. The second enlarged portion is used to prevent the first linkage from detaching from the first guide slide. The rotating block is concave, and a fixing rod is provided within the notch formed by the rotating block. The rotating block is rotatably connected to the first linkage between the two side ears. The sliding block is gate-shaped and includes a horizontal main body, an extension part located below the main body, and a protrusion part extending from the main body. The main body has multiple second through holes penetrating the main body, for example, there can be two second through holes. The extension part is located in a slide groove and slides along the slide groove. The outer surface of the extension part is provided with multiple ribs. The ribs reduce the contact area with the slide groove, thereby reducing friction and improving sliding efficiency. The protrusion part extends into the notch of the rotating block and has a third through hole. The fixed rod is rotatably connected to the third through hole. The number of second connecting rods corresponds to the number of second through holes. The second connecting rods are rotatably connected to the second through holes and both ends extend out of the side plate through the first guide slide.

[0011] Furthermore, the transmission assembly includes gear plates symmetrically arranged on both sides of the slide body, gears corresponding to and meshing with the gear plates, a fourth through hole on the gear plate, a second connecting rod located outside the side plate extending into the fourth through hole and fixedly connected to the gear plate, teeth meshing with the gears on the lower part of the gear plate, and the gears being coaxially fixedly connected to the power output shaft of the motor.

[0012] Furthermore, the motor is fixed to the back of the base plate of the slide body. The motor is connected to the slide body through a motor cover. The motor can be, for example, a bidirectional brushless motor. The motor cover has threaded holes around its perimeter. The motor is placed inside the motor cover, and the motor cover is threadedly connected to the slide body, thereby fixing the motor to the back of the base plate of the slide body.

[0013] Furthermore, a gear cover is provided on the outside of the gear plate to protect the transmission components. The gear cover is threadedly connected to the slide body, for example.

[0014] Beneficial effects:

[0015] This utility model discloses a headlight panel assembly for an electric bicycle. By setting a slide rail body, it provides stable support for the sliding cover, linkage assembly, and transmission assembly. First and second guide slide rails on the side plate ensure the stability and accuracy of the sliding cover during sliding, preventing it from shaking or deviating from its trajectory during operation. A linkage assembly, including a first link, a rotating block, a sliding block, and a second link, enables flexible connection between the transmission assembly and the sliding cover, ensuring normal opening of the sliding cover. A motor drives the transmission assembly, which in turn opens or closes the sliding cover via the linkage assembly, simplifying operation. This electric bicycle headlight panel assembly allows for normal headlight use by opening the sliding cover when needed and closing the cover when the headlight needs to be hidden, reducing headlight exposure time and extending headlight lifespan. Integrating the linkage assembly, sliding cover, transmission assembly, and motor onto the slide rail body reduces the overall size of the headlight panel assembly, making it easy to install on an electric bicycle.
