[0030] Please refer to Figure 1 , Figure 1 which is a schematic diagram of a partial structure of a scooter shown in an exemplary embodiment of the present application.

[0031] The present application provides a scooter, which can be a manual scooter or an electric scooter. The scooter includes a wheel 10 and a shock-absorbing frame 100. Among them, when the wheel 10 is excited, vibrations can be generated. In Figure 1In the illustrated embodiment, the wheel 10 includes a front wheel 11 and a rear wheel 12. During driving, the front wheel 11 and the rear wheel 12 can generate vibrations when excited by an uneven ground.

[0032] The shock-absorbing frame 100 includes a frame 20 and a shock-absorbing assembly 30. The frame 20 includes a front fork assembly 21 and a rear fork assembly 22 that are arranged front and rear and connected ( Figure 1 the X direction in [[ ]] is the front-rear direction of the frame 20). The shock-absorbing assembly 30 includes a first shock absorber 31, a second shock absorber 32, a third shock absorber 33, and a fourth shock absorber 34. The first shock absorber 31 and the second shock absorber 32 are disposed below the front fork assembly 21, supported between the front wheel 11 and the front fork assembly 21, and symmetrically arranged on the left and right sides of the front wheel 11 ( Figure 1 the Y direction in [[ ]] is the left-right direction of the frame 20). The third shock absorber 33 and the fourth shock absorber 34 are disposed below the rear fork assembly 22, supported between the rear wheel 12 and the rear fork assembly 22, and symmetrically arranged on the left and right sides of the rear wheel 12.

[0033] According to the above description, the first shock absorber 31 and the second shock absorber 32 are symmetrically arranged on the left and right sides of the front wheel 11 and supported between the front wheel 11 and the front fork assembly 21. The third shock absorber 33 and the fourth shock absorber 34 are symmetrically arranged on the left and right sides of the rear wheel 12 and supported between the rear wheel 12 and the rear fork assembly 22. This makes the shock-absorbing assembly 30 evenly arranged in the front, rear, left, and right directions of the frame 20. When the wheel 10 generates vibrations and transmits them to the frame 20, the first shock absorber 31, the second shock absorber 32, the third shock absorber 33, and the fourth shock absorber 34 can work together to achieve balanced shock absorption and better comfort experience.

[0034] In one embodiment, the first shock absorber 31 and the third shock absorber 33 are located on the same side of the frame 20, for example, the left side. The second shock absorber 32 and the fourth shock absorber 34 are located on the same side of the frame 20, for example, the right side. Among them, the symmetry center line O of the first shock absorber 31 and the second shock absorber 32 is collinear with the symmetry center line O of the third shock absorber 33 and the fourth shock absorber 34. With this arrangement, the first shock absorber 31, the second shock absorber 32, the third shock absorber 33, and the fourth shock absorber 34 are more evenly distributed on both sides of the frame 20, the supporting force received by the frame 20 is more uniform, and the shock absorption balance is further improved.

[0035] In a specific embodiment, the distance between the first shock absorber 31 and the second shock absorber 32 is equal to the distance between the third shock absorber 33 and the fourth shock absorber 34. The four are distributed in a rectangular structure, and the span of the first shock absorber 31 and the second shock absorber 32 in the left-right direction is equal to the span of the third shock absorber 33 and the fourth shock absorber 34 in the left-right direction. In this way, the span in the front-rear direction is equal, and the structure is relatively more compact.

[0036] In another specific embodiment, the distance between the first shock absorber 31 and the second shock absorber 32 is smaller than the distance between the third shock absorber 33 and the fourth shock absorber 34. The four are distributed in a trapezoidal structure, and the span between the first shock absorber 31 and the second shock absorber 32 in the left-right direction is smaller than the span between the third shock absorber 33 and the fourth shock absorber 34 in the left-right direction, so that the front and rear spans are unequal, and the support stability of the frame 20 is better.

[0037] Please refer to Figure 2 , Figure 2 for Figure 1 Schematic diagram of the front wheel 11 and the front fork assembly 21 shown in FIG.

[0038] In one embodiment, the first shock absorber 31 includes a first shock absorber cylinder 310 and a first shock absorber rod 311 which is telescopically arranged in the first shock absorber cylinder 310, the first shock absorber cylinder 310 is connected to the wheel axle of the front wheel 11, and the first shock absorber rod 311 is connected to the front fork assembly 21. The first shock absorber 31 can be a hydraulic shock absorber or a spring shock absorber, and the shock absorbing medium can be a compressible oil or elastic member, so that the vibration transmitted to the first shock absorber rod 311 can be attenuated by the oil or the elastic member. Among them, the first shock absorber rod 311 can extend in the vertical direction or extend obliquely backward. In this embodiment, the front wheel 11 is more likely to bounce up and down and forward and backward when stimulated, so the extension direction of the first shock absorber rod 311 can be set based on the bouncing direction of the front wheel 11, so that the shock absorbing medium can absorb and mitigate the vibration in a more limited manner, and the shock absorbing effect is better.

[0039] Please continue to refer to Figure 2 In one embodiment, the frame 20 further includes a connecting portion 23 disposed on the front fork assembly 21 and connected to the first shock absorber rod 311, and the extending direction of the connecting portion 23 is collinear with the length direction of the first shock absorber rod 311 or parallel to each other. In one case, the extending direction of the connecting portion 23 is collinear with the length direction of the first shock absorber rod 311, which facilitates the connection between the first shock absorber rod 311 and the connecting portion 23, and the structure also appears to be more integrated and simple. In another case, the extending direction of the connecting portion 23 is parallel to the length direction of the first shock absorber rod 311, for example, the first shock absorber rod 311 and the connecting portion 23 can be connected by a curved adapter to achieve the parallelism of the first shock absorber rod 311 and the connecting portion 23. In this way, during the vibration transmission process, due to the bending of the adapter, part of the vibration will be absorbed and borne by the adapter, and the vibration transmitted to the connecting portion 23 via the first shock absorber rod 311 will be smaller. The connecting portion 23 can adopt a connecting portion of a tubular structure, which is light in weight and has good bending resistance.

[0040] It should be noted that on the other side of the front fork assembly 21, the second shock absorber 32 can adopt the same setting method as the first shock absorber 31, which will not be elaborated here. The second shock absorber 32 can adopt a hydraulic shock absorber or a spring shock absorber.

[0041] In one embodiment, as Figure 2 shown, the shock-absorbing frame 100 further includes a shielding plate 50, the shielding plate 50 shields the side of the front wheel 11 facing the front fork assembly 21, and the shielding plate 50 is fixedly connected to the first shock absorber cylinder 310. With such a setting, the shielding plate 50 can be used to shield the gravel lifted by the vibration of the front wheel 11. In Figure 2 the illustrated embodiment, the shielding plate 50 can shield the water or mud lifted by the rotation of the front wheel 11.

[0042] Please refer to Figure 3 , Figure 3 which is Figure 1 the front view of a partial structure of the scooter shown in

[0043] In one embodiment, the frame 20 further includes a hinge portion 24 provided on the rear fork assembly 22. The hinge portion 24 is provided with a first hinge end 241 and a second hinge end 242. The shock-absorbing frame 100 further includes a connecting rod 40. One end of the connecting rod 40 is hinged to the first hinge end 241, and the other end of the connecting rod 40 is connected to the rear wheel 12. The third shock absorber 33 includes a third shock absorber cylinder 330 and a third shock absorber rod 331 telescopically disposed in the third shock absorber cylinder 330. The third shock absorber cylinder 330 is hinged to the second hinge end 242, and the third shock absorber rod 331 is hinged to the connecting rod 40. Each hinge axis extends in the left-right direction of the frame 20, and each hinge point is distributed at the three vertices of a triangle.

[0044] In the above solution, the connecting rod 40 is hinged to the first hinge end 241, and the third shock absorber cylinder 330 and the third shock absorber rod 331 are respectively hinged to the second hinge end 242 and the connecting rod 40, which increases the degree of freedom when the third shock absorber 33 is connected to the rear fork assembly 22. Specifically, when the rear wheel 12 is excited to generate vibration, the vibration impact force causes the connecting rod 40 to rotate at the first hinge end 241. At this time, the third shock absorber rod 331 is squeezed. However, since the third shock absorber rod 331 is hinged to the connecting rod 40 and the third shock absorber cylinder 330 is hinged to the second hinge end 242, the torque generated by the squeezing force can cause the third shock absorber cylinder 330 and the third shock absorber rod 331 to generate rotational displacement, avoiding damage to the third shock absorber 33 due to torque.

[0045] Please continue to refer to Figure 3, in one embodiment, the third shock absorber rod 331 extends obliquely forward. With this arrangement, the third shock absorber 33 is obliquely connected between the rear wheel 12 and the hinge portion 24. When the rear wheel 12 generates vibrations, these vibrations can cause the connecting rod 40 to rotate, and then be transmitted along the third shock absorber rod 331 to relieve and absorb the vibrations from the rear wheel 12, meeting the stability requirements of the vehicle frame 20.

[0046] Please refer to Figure 4 , Figure 4 is a schematic diagram of the rear fork assembly 22 provided with the hinge portion 24 and the connecting rod 40.

[0047] The hinge portion 24 can be separately provided from the vehicle frame 20. For example, it can be relatively fixed to the rear fork assembly 22 by means of bolt connection or welding.

[0048] In Figure 4 the illustrated embodiment, there are two hinge portions 24, and the two hinge portions 24 are symmetrically arranged on the left and right sides of the rear wheel 12. There are also two connecting rods 40, and the two connecting rods 40 are symmetrically arranged on the left and right sides of the rear wheel 12. And the hinge portion 24 and the connecting rod 40 on the same side form a group. The third shock absorber 33 is hinged to one group of the hinge portion 24 and the connecting rod 40, and the fourth shock absorber 34 is hinged to the other group of the hinge portion 24 and the connecting rod 40. With this arrangement, the installation structure of the third shock absorber 33 is the same as that of the fourth shock absorber 34, the shock absorption effect is more balanced, and the steering is more stable. It should be noted that the specific installation method of the fourth shock absorber 34 is the same as that of the third shock absorber 33, and will not be elaborated here. The third shock absorber 33 and the fourth shock absorber 34 can adopt hydraulic shock absorbers or spring shock absorbers.

[0049] Please refer to Figure 5 , Figure 5 is a schematic diagram of a scooter 200 shown in an exemplary embodiment of the present application.

[0050] The present application also provides a scooter 200 including but not limited to two-wheel scooters, three-wheel scooters, and four-wheel scooters. The scooter includes the shock-absorbing vehicle frame 100 described above.

[0051] The scooter 200 includes a front wheel 11, a rear wheel 12, a handlebar assembly 60, a pedal assembly 70, and a shock-absorbing vehicle frame 100. The first shock absorber 31 connects the front wheel 11 and the front fork assembly 21, the second shock absorber 32 connects the front wheel 11 and the front fork assembly 21, and the front wheel 11 is rotatable relative to the first shock absorber 31 and the second shock absorber 32. Specifically, the first shock absorber 31 and the second shock absorber 32 jointly support between the front wheel 11 and the front fork assembly 21. The front wheel 11 is rotatably connected to the first shock absorber cylinder 310 at the wheel axle, and is also rotatably connected to the cylinder body of the second shock absorber 32 at the wheel axle.

[0052] The third shock absorber 33 connects the rear wheel 12 and the rear fork assembly 22, and the fourth shock absorber 34 connects the rear wheel 12 and the rear fork assembly 22. The rear wheel 12 is rotatable relative to the third shock absorber 33 and the fourth shock absorber 34. Specifically, the third shock absorber 33 and the fourth shock absorber 34 jointly support between the rear wheel 12 and the rear fork assembly 22. The rear wheel 12 is rotatably connected to the third shock absorber cylinder 330 at the axle, and is also rotatably connected to the cylinder body of the fourth shock absorber 34 at the axle.

[0053] The handlebar assembly 60 is connected above the front fork assembly 21 and is for a human hand to hold. The pedal assembly 70 is located between the front wheel 11 and the rear wheel 12, and is fixedly connected to the front fork assembly 21 and the rear fork assembly 22. The pedal assembly 70 is for a human foot to step on.

[0054] For the scooter 200 adopting the shock-absorbing frame 100 described above, the up-and-down vibration of the frame 20 can be reduced, the direct impact on the human body can be reduced, and the comfort during riding can be improved. At the same time, during turning, the shock-absorbing design of the overall vehicle balance can be utilized to increase the steering stability of the overall vehicle.

[0055] The above are only the preferred embodiments of the present application and are not intended to limit the present application.
