Description

Technical Field

[0001] This utility model relates to the field of vehicle frame technology, specifically a novel vehicle frame. Background Technology

[0002] In the structure of a bicycle, the frame is the core load-bearing component, and its performance directly affects riding safety and practicality. Most existing bicycle frames use welded metal tubing or a one-piece molded structure, primarily fulfilling the basic functions of supporting the frame and connecting various components. However, the issue of safety warnings during nighttime riding has long remained unresolved. Traditional bicycle frames lack active lighting or warning functions, relying solely on additional devices such as bells and reflective stickers. Reflective stickers require external light sources to function, and in dimly lit environments without streetlights, their warning effect on vehicles approaching from the side and rear is weak. Additional lights are often fixed to the handlebars or seat, offering limited illumination and failing to adequately alert surrounding road users, thus increasing the risk of collisions. Furthermore, some bicycle frames reduce the amount of tubing in pursuit of lightweight design, resulting in a trade-off between structural strength and warning functions, failing to meet safety requirements in complex road conditions at night. Therefore, developing a new type of frame that integrates nighttime riding warning functions while maintaining structural stability has become a key direction for improving the safety of cycling at night. Utility Model Content

[0017] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6 This utility model provides a novel bicycle frame, including: a rear fork 300, on which a visual warning unit 400 is installed. The visual warning unit 400 can transmit visually perceptible warning information to the rear of the frame by means of light reflection or self-illumination. The visual warning unit 400 includes a connecting tube 410 and an arc-shaped warning element 420. It should be noted that when the bicycle is driven at night, the visual warning unit 400 on the rear fork 300 can transmit visually perceptible warning information to the rear of the frame through the arc-shaped warning element 420 by means of light reflection or self-illumination. Light reflection usually means that the headlights of the vehicle behind shine onto the arc-shaped warning element 420, and the arc-shaped warning element 420 provides a visual reminder to the vehicle behind by reflecting light. Self-illumination usually means that the arc-shaped warning element 420 is connected to a power source and actively emits light to provide a visual reminder to the vehicle behind.

[0018] Example 1: As Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the rear fork includes a rear fork top tube and a rear fork bottom tube. The rear fork top tube and the rear fork bottom tube are fixedly connected by two connecting tubes. The ends of the connecting tubes that connect to the rear fork top tube and the rear fork bottom tube have the same diameter. The connecting tubes, the rear fork top tube, and the rear fork bottom tube can form a tube with a diameter that increases sequentially from bottom to top. An arc-shaped warning element matching the inner diameter of the connecting tube is mounted on the connecting tube through a recessed mounting groove. When the arc-shaped warning element is embedded in the connecting tube, the outer wall of the arc-shaped warning element smoothly transitions with the outer wall of the connecting tube. It is conceivable that the connectors at both ends of the connecting tube 410 are inserted into the upper tube 310 and the lower tube 320 of the rear fork respectively for fixed connection. The connection can be fixed by thread or welding. The connecting tube 410 has a support plate inside to increase the overall strength of the rear fork 300. The two ends of the connecting tube 410 have the same diameter as the upper and lower parts of the rear fork 300, respectively, so as to maintain the integrity and strength of the rear fork 300. The arc-shaped warning piece 420 is completely embedded in the recessed mounting groove of the connecting tube 410, so that the arc-shaped warning piece 420 and the connecting tube 410 form a complete tubular shape, thereby increasing the strength of the connecting tube 410 and the aesthetics of the vehicle body.

[0019] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a seat tube 100 is installed on the upper end of the rear fork 300, and a rear fork support rod 600 is fixedly installed on the bottom end of the rear fork 300. The other end of the rear fork support rod 600 is connected to the lower surface of the seat tube 100. One end of the upper tube 500 is installed on the seat tube 100 near the upper surface of the rear fork 300, and one end of the lower tube 200 is installed on the seat tube 100 near the lower surface of the rear fork support rod 600. The other end of the upper tube 500 is fixedly connected to the other end of the lower tube 200. It is worth noting that the seat post 100, down tube 200, rear fork 300, top tube 500, and rear fork support 600 can be welded together to form the main body of the bicycle frame. During the assembly of the frame, the connecting tube 410 can be installed on the rear fork 300. After the connecting tube 410 is installed, the arc-shaped warning piece 420 can be assembled. After the bicycle frame is assembled, related components such as the seat, steering wheel, and wheels can be assembled to form a complete bicycle. When the bicycle is ridden at night, the arc-shaped warning piece 420 can remind vehicles behind.

[0020] like Figures 1-3 , Figure 5 and Figure 6 As shown, the arc-shaped warning component 420 includes a lamp body 421, which is fitted into a recessed mounting groove of the connecting pipe 410. The outer wall of the lamp body 421 smoothly transitions with the outer wall of the connecting pipe 410. The lamp body 421 is equipped with a power supply or is connected to an external power supply. It is clear that when the bicycle is riding at night, the lamp body 421 has a built-in power supply or is connected to an external power supply. When the lamp body 421 receives power, it will emit light. When the lamp body 421 is lit, it can remind vehicles behind to pay attention to the vehicle in front, improving the safety of riding the bicycle at night. In addition, the outer peripheral surface of the lamp body 421 matches the size of the recessed mounting groove of the connecting tube 410, which can increase the stability of the connecting tube 410. Furthermore, the arc curvature of the light-emitting side of the lamp body 421 is the same as the arc curvature of the outer surface of the connecting tube 410, which can increase the aesthetics of the connecting tube 410.

[0021] like Figure 1 , Figure 2 , Figures 4-6 As shown, the arc-shaped warning component 420 also includes a reflector 422, which is fitted into the recessed mounting groove of the connecting pipe 410, and the outer wall of the reflector 422 smoothly transitions with the outer wall of the connecting pipe 410. It should be considered that when a bicycle is riding at night, when the headlights of a following vehicle shine on the surface of the reflector 422, the reflector 422 will reflect light to visually alert the following vehicle. The outer circumference of the reflector 422 matches the size of the recessed mounting groove of the connecting tube 410, which can increase the stability of the connecting tube 410. In addition, the arc curvature of the light-emitting side of the reflector 422 is the same as the arc curvature of the outer surface of the connecting tube 410, which can increase the aesthetics of the connecting tube 410.

[0022] Example 2: Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the visual warning unit 400 also includes a mounting part 430, a push-out part 440 and a protective part 450. The arc-shaped warning part 420 is connected to the connecting pipe 410 through the mounting part 430. The push-out part 440 and the protective part 450 are respectively mounted on the mounting part 430. It should be noted that the mounting component 430 can fix the arc-shaped warning component 420 on the connecting pipe 410. After the arc-shaped warning component 420 is installed, the protective component 450 can protect one side of the mounting component 430. When the arc-shaped warning component 420 needs to be removed, the push-out component 440 can push the arc-shaped warning component 420 out of the recessed mounting groove of the connecting pipe 410.

[0023] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the mounting component 430 includes an internally threaded post 431, a mounting base 432, a connecting groove 433, and a bolt 434. Two internally threaded posts 431 are symmetrically fixedly installed on the back of the arc-shaped warning component 420. Two mounting bases 432 are fixedly installed on the inner wall of the connecting pipe 410 near the internally threaded posts 431. A connecting groove 433 is provided through the mounting base 432 and the connecting pipe 410. A bolt 434 is connected through the connecting groove 433. The bolt 434 is connected to the internally threaded post 431 by threads. It is conceivable that the arc-shaped warning piece 420 is inserted into the recessed mounting groove of the connecting pipe 410. When the arc-shaped warning piece 420 is inserted, it can drive the internal threaded post 431 to align with the connecting groove 433 on the mounting base 432. After the internal threaded post 431 aligns with the connecting groove 433, the bolt 434 can be inserted into the connecting groove 433, and the bolt 434 can be threadedly connected to the internal threaded post 431 by rotating the bolt 434. When the bolt 434 is threadedly connected, the internal threaded post 431 can be fixed on the mounting base 432.

[0024] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the ejector 440 includes an ejector spring 441 and an annular top plate 442. The ejector spring 441 is fixedly installed on the mounting base 432, and the annular top plate 442 is fixedly installed on the end of the ejector spring 441 near the arc-shaped warning member 420. It is understood that when the arc-shaped warning element 420 is installed, it can drive the internal threaded post 431 to be inserted into the annular top plate 442 and the ejector spring 441. When the internal threaded post 431 is inserted, the annular top plate 442 will contact the back of the arc-shaped warning element 420. At the same time, the arc-shaped warning element 420 can squeeze the surface of the annular top plate 442. When the annular top plate 442 is squeezed, it can compress the ejector spring 441. When the arc-shaped warning element 420 moves to the designated position, it can be fixed by the bolt 434. When the arc-shaped warning piece 420 is being repaired, the bolt 434 needs to be removed. When the bolt 434 is being removed, the annular top plate 442 can move by the elastic force of the ejector spring 441. When the annular top plate 442 moves, it will push the arc-shaped warning piece 420 out of the recessed mounting groove of the connecting pipe 410, so that the arc-shaped warning piece 420 can be quickly removed.

[0025] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the protective component 450 includes a cover plate 451, a sealing plug 452, and a groove 453. The cover plate 451 is movably installed in the connecting groove 433. The sealing plug 452 is fixedly installed on the side of the cover plate 451 near the bolt 434. The other side of the cover plate 451 is provided with a groove 453 for disassembly. It should be considered that after the arc-shaped warning piece 420 is installed, the cover plate 451 can be inserted into the connecting groove 433. When the cover plate 451 is inserted, it can drive the sealing plug 452 to be squeezed to the end of the bolt 434 for sealing. When bolt 434 needs to be removed, fingers can be inserted into groove 453 to rotate and pull cover plate 451, thereby allowing for quick removal of cover plate 451.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
