DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] Embodiment 1

[0042] Referring to Figures 1-4 The damping mechanism provided in the embodiment comprises a front wheel damping assembly, which comprises a front wheel damper A1, a front axle swing arm A3 made of aluminum alloy material by cold forging, and a U-shaped front wheel damping arm A2, and the three are fixed in a triangular structure.

[0043] The front wheel damping arm A2 comprises a middle rod A21 at the lower part thereof, and a side rod I A22 and a side rod II A23 connected at both ends of the middle rod A21 respectively, and the middle part of the middle rod A21 is connected with the axle of the front wheel A.

[0044] One end of the front wheel damper A1 is hinged with the upper end of the side rod I A22, so that the front wheel damping arm A2 and the front wheel damper A1 can rotate adaptively relative to each other. The other end of the front wheel damper A1 is hinged with the front axle swing arm A3, so that the front wheel damper A1 can rotate adaptively relative to the front axle swing arm A3 about the hinged center line of the front axle swing arm A3 and the front wheel damper A1.

[0045] The lower end of the front axle swing arm A3 is hinged with the side rod II A23, so that the front wheel damping arm A2 can rotate adaptively relative to the front axle swing arm A3 about the hinged center line of the front axle swing arm A3 and the front wheel damping arm A2.

[0046] The upper end of the front axle swing arm A3 is connected with the stand pipe C of the scooter, and the lower end of the front axle swing arm A3 is located outside the upper end, that is, it is inclined outward from top to bottom, which can not only strengthen the strength, but also provide enough space for the front wheel shock absorber, and facilitate the disassembly and assembly of the front wheel shock absorber.

[0047] The front wheel shock absorber A1 is installed at a certain angle with the axis (X axis, the right direction is positive) parallel to the road surface with the connecting point of the front wheel shock absorber A1 and the side rod I A22 as the axis (rotation point). Specifically, the installation angle of the front wheel shock absorber A1 ranges from -30° to the same angle as the center axis of the stand pipe C. Within the above angle range, the side rod I A22 is located in front of the side rod II A23, and the front axle swing arm A3 is located behind the stand pipe C. Preferably, as shown in Figure 2 The installation angle of the front wheel shock absorber A1 is -30°, and the rear end of the front wheel shock absorber A1 is connected to the lower part of the front axle swing arm A3; as shown in Figure 4 The installation angle of the front wheel shock absorber A1 is 30°, and the rear end of the front wheel shock absorber A1 is connected to the upper part of the front axle swing arm A3. More preferably, as shown in Figure 3 The installation angle of the front wheel shock absorber A1 is 0°, at this time, the front wheel shock absorber A1 is parallel to the road surface, and the weight requirement of the front wheel shock absorber A1 is reduced to the minimum value. A shorter stroke front wheel shock absorber A1 can be used to reduce the cost. The multi-angle installation mode of the front wheel shock absorber A1 makes the front wheel shock absorber A1 realize free installation, and the appropriate installation angle of the front wheel shock absorber A1 can be selected according to different vehicle models and installation space size, so as to facilitate the disassembly and maintenance of the front wheel shock absorber A1.

[0048] The above-mentioned front wheel shock absorber A2 is two and is arranged in a left-right alignment with the front axle swing arm A3 as the center. The two front wheel shock absorber A2 are an integral structure, which increases the structural stability. The front wheel shock absorber A1 and the front axle swing arm A3 are respectively located between the left front wheel shock absorber A2L and the right front wheel shock absorber A2A2R. This arrangement makes the gap between the two front wheel shock absorbers A2 and the front wheel shock absorber A1 and the front axle swing arm A3 more compact and reasonable, and also increases the support effect on the front wheel A.

[0049] The connecting part of the upper end of the two side rods IA22 is provided with a mounting seat A24, which is hinged with the front end of the front wheel shock absorber A1. The connecting part of the upper end of the two side rods IIA23 is inwardly recessed to form a mounting opening which is matched with the lower end of the front axle swing arm A3. The lower end of the front axle swing arm A3 is mounted in the mounting opening by the front axle swing arm fixing shaft A31 which is made of high-strength steel. This arrangement not only makes full use of the space and reduces the overall size of the shock absorbing mechanism, but also ensures the stability of the mounting. The front axle swing arm A3 is a hollow frame. Under the premise of ensuring the strength of the hollow frame, the weight of the front axle swing arm A3 is reduced, making the scooter more lightweight. The rear end of the front wheel shock absorber A1 is hinged inside the hollow frame. This arrangement makes full use of the space and makes the structure between the front wheel shock absorber A1 and the front axle swing arm A3 more compact.

[0050] The middle part of the intermediate rod A21 is provided with a front wheel shaft positioning hole A26 at the lower end. The front wheel shaft of the front wheel A is connected with the front wheel shaft positioning hole A26. The specific installation method is as follows: the front wheel shaft of the front wheel A passes through the front wheel shaft positioning hole A26 on one side of the intermediate rod A21, the front wheel A disc brake, the front wheel A bearing in turn, and then passes through the front wheel A bearing on the other side and the front wheel shaft positioning hole A26 in turn, so that the front wheel shaft of the front wheel A leaves the same length on both sides of the front axle swing arm A3. The two sides are respectively sleeved with flat pads and elastic pads, the nuts are tightened, the decorative cover is covered, the screws are tightened, and the decorative cover is fixed.

[0051] The front wheel shock absorber A1 is one of a spring shock absorber, a hydraulic shock absorber and an air shock absorber. For example, when driving on urban roads, the air pressure shock absorber can be selected to improve the driving comfort; when driving on highways, the hydraulic shock absorber can be selected to improve the driving stability; when driving on rough roads, the hydraulic shock absorber can be selected to improve the driving stability and passability.

[0052] The shock absorbing principle of this embodiment will be described in detail below with the front wheel shock absorber A1 as a spring shock absorber as an example:

[0053] Referring to Figure 6force analysis diagram, the front tire is pressed over the protrusion, the front tire is subjected to an upward force, which will make the front tire upward, and the force is transmitted to the front wheel shock absorber arm A2, the force is shunted to the side rod IA22 and the side rod IIA23 through the U-shaped front wheel shock absorber arm A2, and then transmitted to the front axle swing arm A3 through the side rod IIA23, the front axle swing arm A3 will be subjected to an upward force and lifted up, since the front axle swing arm A3 and the front wheel shock absorber arm A2 are axially limited by the front axle swing arm fixing shaft A31, only the circumferential movement can be made. The upward force on the front tire is axially limited by the front axle swing arm fixing shaft A31, part of the force is absorbed by the front axle swing arm fixing shaft A31 and the front axle swing arm A3 and transmitted upward, and part of the force will make the front wheel shock absorber arm A2 and the front tire move in a circular motion with the front axle swing arm fixing shaft A31 as the center, and the force is transmitted to the side rod IA22, and the front axle swing arm A3 is transmitted obliquely to the spring shock absorber, at this time the direction of the force is further turned, the spring shock absorber is subjected to the obliquely transmitted force F1, and the spring is elastically deformed to offset part of the force from the side rod IA22. The other part of the force shunted to the side rod IA22 through the U-shaped front wheel shock absorber arm A2, the force on the side rod IA22 is turned and transmitted upward to the spring shock absorber, at this time the direction of the force is turned again, the spring shock absorber is subjected to the obliquely transmitted force F2, and the spring is elastically deformed, at this time the spring shock absorber is subjected to the force in both left and right directions, and the deformation reaches the maximum state. The spring characteristics will make it return to its original state, and the spring can slow down the direct release of the force in the process of returning to its original state, the slowed-down released force will offset part of the forces in the two directions F1 and F2, the remaining force is weakened by the shock absorber and transmitted to the front axle swing arm A3, and the force transmitted to the front axle swing arm A3 is shunted, part of the force is further turned in direction and transmitted to the vertical pipe C, and the other part is transmitted to the frame D. Each turning of the force will lose part of the force, part of the force is absorbed by the front shock absorbing mechanism, and part of the force is further absorbed by the frame D. When continuously subjected to an upward force (the front tire continuously presses over multiple protrusions), the force arm is lengthened by the intermediate rod A21, and the force direction is turned multiple times by the structure of the entire front wheel shock absorbing assembly, and the release speed of the slowed-down force of the spring shock absorber is further slowed down, the force not yet released by the spring shock absorber in the first reverse direction will be offset by the second forward force (opposite to the transmission direction of the released force of the spring shock absorber returning to its original state), the third forward force can offset the force not yet released by the second spring shock absorber in the reverse direction, and so on, each force (forward force) can offset part of the elastic deformation force (i.e. the released force of the spring shock absorber returning to its original state) of the previous force, so as to make the shock absorbing mechanism play the maximum shock absorbing effect, the force transmitted to the human body is smaller and the vibration is less obvious, and the user's control is more stable, which invisibly enhances the safety of the user during driving.

Most preferably, as shown in Figure 5 The mounting angle of the front wheel shock absorber A1 is 180°, at which time the front wheel shock absorber A1 is parallel to the road surface, the requirement for the front wheel shock absorber A1 is reduced to the minimum value, a shorter stroke front wheel shock absorber A1 can be used, and the cost is reduced.
