Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, and in particular to an inverted shock-absorbing front fork structure. Background Technology

[0002] When using bicycles, inverted suspension forks are often used. The design feature of an inverted suspension fork is that the configuration of the shock-absorbing components is reversed, which changes the vertical position of the shock absorber. Therefore, it is very important to be able to sense the speed at the first moment while riding.

[0003] In existing technologies, some inverted shock-absorbing fork structures exhibit slow response times during use, failing to effectively absorb and disperse impact forces in a timely manner. This delay not only affects riding stability and comfort but also increases the risk of system failure under high-intensity riding conditions. Therefore, an inverted shock-absorbing fork structure is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an inverted shock-absorbing front fork structure, which aims to improve the problem that some devices in the prior art cannot respond in time, resulting in increased device delay.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An inverted shock-absorbing front fork structure includes a connecting column, a connecting frame fixedly connected to the outside of the connecting column, a combination frame fixedly connected to the bottom of the connecting column, two fixing rings fixedly connected to the top of the connecting frame, an actuating inner tube fixedly connected to the bottom of the two fixing rings, a fixing assembly for fixing fixedly connected to the outside of the actuating inner tube, a connecting assembly for connection fixedly connected to the bottom of the actuating inner tube, the connecting assembly including a connecting block, an anti-rotation plate fixedly connected to the bottom of the connecting block, and a support frame rotatably connected to the rear outer side of the two connecting blocks.

[0007] As a further description of the above technical solution:

[0008] The connecting assembly includes two connecting blocks. The two connecting blocks are externally fixedly connected to the bottom of the actuating inner tube. A connecting ring is fixedly connected to the front side of the two connecting blocks. A fastening plate is fixedly connected to the outside of the connecting ring. A fixing post is fixedly connected to the adjacent side of the two fastening plates.

[0009] As a further description of the above technical solution:

[0010] The fixing component includes a fixing frame, which is externally fixedly connected to the outside of the connecting column, and the fixing frame has multiple holes and slots inside;

[0011] As a further description of the above technical solution:

[0012] The two actuating inner tubes are externally coupled to an outer tube, and the outer side of the actuating inner tube slides inside the outer tube through an internal connecting ring;

[0013] As a further description of the above technical solution:

[0014] The outer part of the connecting frame is at the bottom top of the combined frame, and the outer part of the actuating inner tube passes through the interior of the combined frame and the connecting frame.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the speed can be quickly sensed from the bottom through the connecting block. Its design can reflect the speed in the first time. This fast feedback mechanism ensures that the system can react to speed changes in real time, improves the overall response performance of the device, thereby enhancing the controllability of riding, and at the same time can better reduce delay.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1 to 3 , Figure 7 This utility model provides an embodiment of an inverted shock-absorbing front fork structure, including a connecting column 1. A connecting frame 202 is fixedly connected to the outside of the connecting column 1, which is designed to improve the stability and deformation resistance of the overall structure. A combination frame 204 is fixedly connected to the bottom of the connecting column 1. The function of the combination frame 204 is to support and integrate various components from the connecting frame 202. Two fixing rings 201 are fixedly connected to the top of the connecting frame 202. An actuating inner tube 203 is fixedly connected to the bottom of the two fixing rings 201, which can ensure good connection performance and durability. A fixing component for fixing is fixedly connected to the outside of the actuating inner tube 203. A connecting component for connection is fixedly connected to the bottom of the actuating inner tube 203. The connecting component includes a connecting block 206, which has excellent load-bearing capacity and is convenient for docking and fixing with other parts. An anti-rotation plate 208 is fixedly connected to the bottom of the connecting block 206, which is designed to prevent damage to the motor shaft. A support frame 207 is rotatably connected to the rear of the two connecting blocks 206 for adjusting other structures.

[0029] The connecting assembly includes two connecting blocks 206, which are externally fixedly connected to the bottom of the actuating inner tube 203. A connecting ring 303 is fixedly connected to the front of the two connecting blocks 206. A fastening plate 304 is fixedly connected to the outside of the connecting ring 303. The connecting ring 303 has a ring structure and is externally fixedly connected to the fastening plate 304. The fastening plate 304 has the function of ensuring the overall structure is tight. A fixing post 305 is fixedly connected to the adjacent side of the two fastening plates 304. The design of the fixing post 305 enables the entire structure to maintain high stability and reliability during use, effectively preventing loosening or displacement.

[0030] Reference Figure 5 and Figure 6 The fixing component includes a fixing frame 301, which is designed to form a robust connection point to provide necessary support and stability. The fixing frame 301 is externally fixed to the outside of the connecting column 1. The fixing frame 301 has multiple slots 302 inside, which can effectively reduce the overall weight while maintaining the strength of the structure. The two actuating inner tubes 203 are externally coupled to an outer tube 205, which is cylindrical in shape and has its other side cut off to ensure that it can slide smoothly during the movement of the inner tubes. The wall thickness of the outer tube 205 is optimized to ensure sufficient strength without deformation when subjected to external impact and internal pressure. The outer side of the actuating inner tube 203 slides inside the outer tube 205 through an internal connecting ring 303. Through this sliding design, the actuating inner tube 203 can move flexibly. The outer side of the connecting frame 202 is at the bottom and top of the combined frame 204, and the outer side of the actuating inner tube 203 passes through the interior of the combined frame 204 and the connecting frame 202.

[0031] Working Principle: First, the connecting column 1 serves as the core support of the entire device, and its exterior is fixedly connected to the connecting frame 202, providing the necessary basic stability. During riding, the impact force from uneven road surfaces is first absorbed by the connecting frame 202 and transmitted to other components through the connecting column 1, reducing the direct impact of vibration. Then, the bottom of the connecting column 1 is fixedly connected to the combination frame 204. The design of the combination frame 204 allows it to bear various components and forces from the connecting frame 202, making the overall structure more stable. The two fixing rings 201 at the top of the connecting frame 202 provide additional connection points, and the bottom of the actuating inner tube 203 is fixedly connected, ensuring a tight connection between these components and helping to maintain good connection performance and durability during use. The bottom of the connecting block 206 is fixedly connected to an anti-rotation plate 208. This design prevents the torsional force generated by the motor shaft during operation from causing potential damage to other components, thereby protecting the overall performance of the electric bicycle. Meanwhile, a support frame 207 is rotatably connected to the outer rear side of the two connecting blocks 206, allowing for precise adjustment during actual use. A connecting ring 303 is fixedly connected to the outer front side of the two connecting blocks 206, and a fastening plate 304 is fixedly connected to its exterior. The annular connecting ring 303 and the fastening plate 304 combine to form a robust connection. The design of these fastening plates 304 not only ensures the overall tightness of the structure but also enhances the reliability of the connection, preventing loosening or displacement caused by vibrations generated during riding.

[0032] The fixing frame 301, as a structural support component, is securely fixed to the outside of the connecting column 1, providing the necessary stability and a robust connection point for the entire device. The fixing frame 301 has multiple slots 302 inside; this design effectively reduces the overall weight while maintaining necessary strength, ensuring safety under dynamic loads. During operation, the two actuating inner tubes 203 are coupled through the outer tube 205. The outer tube 205 is cylindrical, with one side cut open; this design allows the actuating inner tube 203 to slide freely inside, ensuring dynamic fit between the pipes during operation. When the actuating inner tube 203 is subjected to external impact or movement, the inner tube slides smoothly inside the outer tube 205, helping to buffer the force acting on the structure. Its bottom-driven actuation design allows for immediate contact and release of the released velocity, further improving performance.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
