Description

Technical Field

[0001] The invention relates to a front shock absorbing structure of a scooter and the scooter, belonging to the technical field of scooters. Background Art

[0002] With the progress of society, people pay more and more attention to environmental protection and green travel. In order to meet the short-distance travel needs of users, various scooters have emerged. Scooters are suitable for use by people of all ages because of their moderate speed, easy to learn and operate, and brake devices. They are especially popular among teenagers. Scooters are prone to bumps when passing through uneven roads, which affects safe driving and comfort. Therefore, it is necessary to set a shock absorbing device on the scooter. At present, the front shock absorption of scooters is often achieved by installing shock absorbers in the axial direction of the connecting rod. This installation method can only maintain shock absorption in the axial direction parallel to the connecting shaft. For users supported on the skateboard, its shock absorption effect is limited. In addition, when the scooter encounters a bumpy road section, its shock absorber is in a compressed state and then elastically reset. If the impact of its elastic force is too large, it will be difficult to turn. Summary of the invention

The front end of the lower rocker arm 5 is connected to the upper universal valve 92, and the rear end of the lower rocker arm 5 is connected to the rear end of the upper rocker arm 4 through the upper rocker arm connection shaft 44. Preferably, the upper universal valve 92 and the lower universal valve 91 are ball valves.

[0023] Specifically, as shown in Figure 4 FIG. 0, the upper rocker arm 4 and the lower rocker arm 5 both have a bifurcated structure. The upper rocker arm 4 includes a front end connecting portion 41, a first bifurcated portion 42 and a second bifurcated portion 43. The front ends of the first bifurcated portion 42 and the second bifurcated portion 43 are both connected to the rear end of the front end connecting portion 41. The lower rocker arm 5 includes a front end connecting portion 51, a first bifurcated portion 52, and a second bifurcated portion 53. The front ends of the first bifurcated portion 52 and the second bifurcated portion 53 are both connected to the rear end of the front end connecting portion 51. The front end connecting portion 41 of the upper rocker arm 4 is fixedly connected to the two connecting rods 3 through a first connecting plate 71.

The upper and lower ends of the front end connecting portion 41 of the upper rocker arm 4 are respectively fixedly connected to the middle openings of the first connecting plate 71 and the middle opening of the second connecting plate 72, so that the front end connecting portion 41 is limited between the first connecting plate 71 and the second connecting plate 72. Since the first connecting plate 71 and the second connecting plate 72 are both fixedly connected to the connecting rod 3, the upper rocker arm 4 is fixedly connected to the two connecting rods 3. The lower universal valve 91 is placed in the middle opening of the third connecting plate 73. By the relative rotation between the upper and lower universal valves 91, the steering of the scooter can be realized. Even when receiving the elastic impact force of the shock absorber 31 and the front shock structure A, the steering of the scooter can be easily realized. And by adding a front shock mechanism to the scooter, during the shock absorption process, the swing arm is larger and the offset angle is larger, having a better shock absorption effect.

The rear bracket 11 is fixedly connected to the rear end of the pedal 1. The two rear connecting plates are arranged oppositely, the two first rear connecting rods 13 are arranged oppositely, and the two second rear connecting rods 14 are arranged oppositely. A first rear connecting rod connecting shaft 134, a second rear connecting rod connecting shaft 135, and a third rear connecting rod connecting shaft 136 are connected between the two first rear connecting rods 13. The first rear connecting rod connecting shaft 134 is hinged to the rear end of the pedal 1. The upper end of the rear shock absorption spring 15 is connected to the rear bracket 11, and the lower end is connected to the third rear connecting rod connecting shaft 135. The two second rear connecting rods 14 are arranged oppositely. One ends of the two second rear connecting rods 14 are respectively hinged to both ends of the second rear connecting rod connecting shaft 135. A fourth rear connecting rod connecting shaft 141 is connected between the other ends of the two second rear connecting rods 14. The rear ends of the two rear connecting plates 12 are respectively connected to the left and right sides of the rear wheel 16. The front ends of the two rear connecting plates 12 are respectively connected to both ends of the first rear connecting rod connecting shaft 134, and the two rear connecting plates 12 are respectively connected to both ends of the fourth rear connecting rod connecting shaft 141.

[0026] Specifically, a main shaft is provided on the rear wheel 16. The main shaft penetrates through the rear wheel 16, and the rear ends of the two rear connecting plates 12 are connected to both ends of the main shaft. As Figure 8 shown in the figure, the cross-section of the first rear connecting rod 16 is in a triangular structure. First fixing holes 131, second fixing holes 132, and third fixing holes 133 are respectively provided at the positions corresponding to the three corners of the first rear connecting rod 16. The first fixing hole 131 and the third fixing hole 132 are respectively close to the pedal 1 and the rear wheel 16. The second fixing hole 132 is located at the middle position between the first fixing hole 131 and the third fixing hole 133. Both ends of the first rear connecting rod connecting shaft 134 are connected between the first fixing holes 131 of the two first rear connecting rods 16. Both ends of the second rear connecting rod connecting shaft 135 are connected between the second fixing holes 132 of the two first rear connecting rods 16. Both ends of the third rear connecting rod connecting shaft 136 are connected between the third fixing holes 133 of the two first rear connecting rods 16.

[0027] It can be seen from the above description that by adding a front shock absorption mechanism to the scooter, during the shock absorption process, the swing arm is larger and the deflection angle is larger, having a better shock absorption effect. Moreover, the relative rotation between the upper and lower universal valves 91 in the front shock absorption mechanism can achieve the steering of the scooter. Even when receiving the elastic impact force of the shock absorber 31 and the front shock absorption structure A, it is also easy to achieve the steering of the scooter. In addition, by setting a multi-link rear shock absorption mechanism, it is convenient to disperse the pressure during shock absorption, making the stress points more dispersed and having a better shock absorption effect.

[0028] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation manners. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection required by the present invention.
