Description

Technical Field

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

[0002] An electric scooter is a small personal mobility device powered by a battery and driven by an electric motor. It typically features a standing or sitting footrest, two (or three) wheels, a vertical steering bar, and handlebars. Users control direction and balance by shifting their body weight and turning the handlebars. Its core features include compactness, lightweight design, ease of operation, and energy efficiency, making it widely used for short-distance urban commuting, shared mobility, and leisure activities.

[0003] Currently, most electric scooters use rigid front forks or simple spring shock absorption structures, which have limited shock absorption effects and are difficult to effectively cope with multi-directional impacts on complex road surfaces. Especially when riding at high speeds or on bumpy roads, vibrations are directly transmitted to the handlebars and pedals, affecting riding comfort and handling stability. Existing shock-absorbing front forks mostly use a single vertical shock absorption method, which lacks the ability to absorb lateral forces and torques. In addition, the structure is loose and the linkage efficiency of various components is low, resulting in sluggish shock absorption response and insufficient energy dissipation. Long-term use can easily lead to problems such as component wear or oil leakage.

[0004] Therefore, how to provide shock-absorbing front forks for electric scooters is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to propose a shock-absorbing front fork for electric scooters. This shock-absorbing front fork employs a multi-link linkage mechanism to convert impact into longitudinal displacement. It efficiently buffers and absorbs energy through a spring and hydraulic composite system, resulting in a stable and compact structure that effectively reduces vibration and improves riding comfort, handling, and safety, thereby solving the problems mentioned in the background art.

[0006] According to an embodiment of the present invention, an electric scooter shock-absorbing front fork includes a scooter pedal and a pole tube. A third connecting shaft is provided at the top of the outer wall of the pole tube. Two connecting rods are hinged to each other on both sides of the outer wall of the third connecting shaft. A support connecting shaft is rotatably connected between the ends of the connecting rods away from the pole tube. A movable rod is provided in the middle of the outer wall of the support connecting shaft. A shock absorber housing is fixedly connected to the bottom end of the movable rod. The top of the inner wall of the shock absorber housing is slidably connected to the movable rod. A helical spring is fixedly connected to the outer wall of the bottom end of the movable rod. A base plate is fixedly connected to the bottom end of the helical spring.

[0007] As a preferred embodiment of this utility model: the base plate is fixedly connected to the shock absorber housing, a base rod is fixedly connected to the bottom end of the base plate, and a second connecting shaft passes through the outer wall of the base rod.

[0008] As a further preferred embodiment of this utility model: the outer wall of the second connecting shaft is rotatably connected to both the front and rear sides of the outer wall, and the outer wall of the second connecting shaft is rotatably connected to the front fork connecting plate.

[0009] As a further preferred embodiment of this utility model: the end of the connecting rod away from the second connecting shaft is rotatably connected to a connecting shaft, and the connecting shaft is rotatably connected to the upright tube.

[0010] As a further preferred embodiment of this utility model: the left ends of the two connecting rods are respectively rotatably connected to rotating shafts, the outer walls of the rotating shafts are provided with front fork connecting plates, the bottom ends of the front fork connecting plates are threadedly connected with connecting pins, and the outer walls of the connecting pins are provided with rollers.

[0011] As a further preferred embodiment of this utility model: a piston rod is fixedly connected to the middle of the bottom end of the movable rod, and a hydraulic block is slidably connected to the bottom end of the piston rod.

[0012] As a further preferred embodiment of this utility model: a connector is provided at the top of the pole tube, and a telescopic pole tube is snapped into the top of the connector. A scooter handle is fixedly connected to both sides of the top of the telescopic pole tube.

[0013] As a further preferred embodiment of this utility model: a roller is provided in the middle of the right side of the scooter pedal, and a diagonal connecting rod is fixedly connected to the top left side of the scooter pedal, with the end of the diagonal connecting rod away from the scooter pedal being fixedly connected to the upright tube.

[0014] The beneficial effects of this utility model are:

[0015] This electric scooter's shock-absorbing front fork uses a multi-link mechanism (including links one, two, three, and the movable rod) to work together to convert road impacts into longitudinal displacement, which is then buffered by a combination of coil springs and hydraulic piston rods, significantly improving shock absorption efficiency and energy absorption capacity. The upright tube and diagonal linkage enhance the overall structural stability, and the telescopic upright tube design accommodates users of different heights. The front fork connecting plate and rollers are integrated to enable flexible steering.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the shock-absorbing front fork of the electric scooter includes a scooter footboard 1 and a pole tube 4. A third connecting shaft 21 is provided at the top of the outer wall of the pole tube 4. Two connecting rods 25 are hinged to the two sides of the outer wall of the third connecting shaft 21, with connecting rods 3 9 passing through them. A support connecting shaft 23 is rotatably connected between the ends of the connecting rods 3 9 away from the pole tube 4. A movable rod 10 is provided in the middle of the outer wall of the support connecting shaft 23. A shock absorber housing 12 is fixedly connected to the bottom end of the movable rod 10. The top of the inner wall of the shock absorber housing 12 is slidably connected to the movable rod 10. A coil spring 18 is fixedly connected to the bottom outer wall of the movable rod 10. A base plate 17 is fixedly connected to the bottom end of the coil spring 18. The base plate 17 is fixedly connected to the shock absorber housing 12. A base rod 14 is connected, and a second connecting shaft 20 passes through the outer wall of the base rod 14. Connecting rods 3 are rotatably connected to both the front and rear sides of the outer wall of the second connecting shaft 20, and the outer wall of the second connecting shaft 20 is rotatably connected to the front fork connecting plate 11. Connecting shaft 19 is rotatably connected to the end of connecting rod 3 away from the second connecting shaft 20, and connecting shaft 19 is rotatably connected to the upright tube 4. Rotating shaft 24 is rotatably connected to the left end of connecting rod 5. Front fork connecting plate 11 is provided on the outer wall of rotating shaft 24. Connecting pin 13 is threaded between the bottom ends of front fork connecting plate 11. Roller 2 is provided between the outer walls of connecting pin 13. Piston rod 15 is fixedly connected to the middle of the bottom end of movable rod 10, and hydraulic block 16 is slidably connected to the bottom end of piston rod 15.

[0026] When the electric scooter encounters a bump, the force applied to the pedal 1 causes the connecting rod 3 at the bottom of the upright tube 4 to move downwards, driving the connecting rods 5 and 9 on both sides to rotate and press down around the left end. The connecting rod 9 pushes the movable rod 10 downwards, compressing the coil spring 18 and piston rod 15 inside the shock absorber housing 12. The spring generates a reverse elastic force after being compressed, which is transmitted back to the connecting rods 9 and 5 via the movable rod 10, and finally achieves buffering and shock absorption through the upright tube 4. Throughout the process, the connecting rod 3, the base plate 17, the connecting shaft 19, the second connecting shaft 20, and other auxiliary components work together to complete the force transmission and shock absorption functions.

[0027] refer to Figure 1 , Figure 2 As shown, a connector 6 is provided at the top of the pole tube 4, and a telescopic pole tube 7 is snapped onto the top of the connector 6. Both sides of the top of the telescopic pole tube 7 are fixedly connected to scooter handles 8. A roller 2 is provided in the middle of the right side of the scooter pedal 1. A diagonal connecting rod 22 is fixedly connected to the top of the left side of the scooter pedal 1. The end of the diagonal connecting rod 22 away from the scooter pedal 1 is fixedly connected to the pole tube 4.

[0028] The connector 6 allows for adjustment of the height of the telescopic pole tube 7. The 3 diagonal connecting rods 22 connect the scooter pedal 1 and the pole tube 4. The rollers 2 enable movement of the scooter pedal 1.

[0029] Working principle:

[0030] When the electric scooter encounters bumps during movement, the scooter footboard 1 experiences a downward force, and the connecting rod 3 at the bottom of the outer wall of the upright tube 4 experiences a downward force. Simultaneously, the ends of the connecting rods 2 and 5 on both sides of the shock-absorbing assembly near the upright tube 4 move downward, also causing the ends of the connecting rods 3 and 9 near the upright tube 4 to move downward. Due to the downward force on connecting rods 3 and 9 and connecting rods 2 and 5, they rotate downward around their left connection point. Connecting rod 3 and 9 causes the hinged movable rod 10 to move downward. The movable rod 10 pushes the coil spring 18 and piston rod 15 on the inner wall of the shock absorber housing 12 at the bottom to move downward. The coil spring 18 experiences a downward compressive force, and the piston rod 15 causes the hydraulic block 16 to move downward. When the coil spring 18 loses its downward force, it is compressed and generates a reverse elastic force. This force is transmitted through the coil spring 18 to the movable rod 10, then through the movable rod 10 to the connecting rod 3 and 9, and finally through the upright tube 4 to the connecting rod 2 and 5, thus achieving a buffering effect against bumps.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
