This ensures that the angle between the first adjusting arm 32 and the second adjusting arm 33 is constant, thus ensuring that the relative position of the first adjusting arm 32 and the second adjusting arm 33 remains constant. For example, the first adjusting arm 32, the second adjusting arm 33, and the main lever 31 may be integrally formed, or may be separately provided and then assembled.

The second mounting portion 20 to which the adjusting lever 3 is rotatably connected, that is, the main lever 31 is connected to the second mounting portion 20 of the rocker arm 2 in a penetrating manner will be described below.

Since the adjustment of the damper 4 depends on the position change of the first adjusting arm 32, the first adjusting arm 32 may be disposed inside the rocker arm 2 or outside the rocker arm 2, but for convenience of adjustment by a common user, in this embodiment, the first adjusting arm 32 is disposed outside the rocker arm 2, so that the user can directly and manually adjust the position of the first adjusting arm 32 to change the position of the damper 4, thereby adjusting the softness of the damper 4.

In this embodiment of the present application, the length of the first adjusting arm 32 is set to be greater than the length of the second adjusting arm 33, since the position of the first adjusting arm 32 is changed to adjust the position of the shock absorber 4, so that the effective arm length of the shock absorber 4 in the compression process and the height of the base 1 relative to the ground are adjusted, and the shock absorber 4 is connected with the second adjusting arm 33, when the buffering direction of the shock absorber 4 and the length direction of the second adjusting arm 33 are in the same straight line, the distance between the base 1 and the bottom surface is the smallest, in order to make the smallest distance between the base 1 and the bottom surface meet the running requirement of the scooter, the total length of the shock absorber 4 and the second adjusting arm 33 is required, because the shock absorber 4 can play the role of buffering and damping, the length of the shock absorber 4 should be as long as possible, at this moment, the length of the second adjusting arm 33 will be shortened, so that the length of the first adjusting arm 32 is set to be greater than the length of the second adjusting arm 33 according to the difference between the first adjusting arm 32 and the second adjusting arm 33.

In some embodiments, referring to fig. 3, a plurality of first positioning portions 6 are provided around the first mounting portion 12 or around the second mounting portion 20, the plurality of first positioning portions 6 being disposed at intervals along the circumferential direction of the main lever 31; the first adjusting arm 32 is detachably connected with any one of the first positioning portions 6 by a locking member. Therefore, the first adjusting arm 32 can be adjusted in a plurality of positions, so that the effective arm length of the shock absorber 4 in the compression process and the height of the base 1 relative to the ground can be freely adjusted between a plurality of gears, the hardness of the shock absorber 4 can be adjusted, different road conditions can be met, the position of the first adjusting arm 32 can be directly adjusted by a common user, and the adjustment reliability and convenience of the shock absorber 4 are greatly improved.

It should be noted that, since the first adjusting arm 32 is rotated along the circumferential direction of the main lever 31 to change the position, the plurality of first positioning portions 6 are disposed at intervals along the circumferential direction of the main lever 31, that is, the plurality of first positioning portions 6 are distributed in an arc shape, so that the first adjusting arm 32 can be detachably connected with the corresponding first positioning portion 6 to fix the current position of the first adjusting arm 32 no matter the first adjusting arm 32 rotates to any position.

For example, referring to fig. 3, the main lever 31 is rotatably connected to the second mounting portion 20 provided on the rocker arm 2, and a plurality of first positioning portions 6 may be disposed on the rocker arm 2 and distributed around the second mounting portion 20 in an arc shape, where when the first adjusting arm 32 is detachably connected to a different first positioning portion 6, the position of the first adjusting arm 32 may be changed, so that the position of the damper 4 connected to the second adjusting arm 33 may be changed, and further, the purpose of adjusting the hardness degree of the damper 4 and the height of the base 1 relative to the bottom surface may be achieved.

In some embodiments, referring to fig. 3, an end of the first adjusting arm 32 away from the main lever 31 is provided with a connecting hole 34, and the first positioning portion 6 is a positioning hole; the locking member is a retractable pin or screw that passes through the attachment aperture 34 and the locating aperture to lock the current position of the first adjustment arm 32. Therefore, the damper 4 can be adjusted without disassembling parts for common users, and the reliability and convenience of adjustment are greatly improved.

In some embodiments, the distances between adjacent two first positioning portions 6 are equal. Therefore, the rotation angle of the first adjusting arm 32 can be kept consistent each time, that is, the adjustable gear angle of the shock absorber 4 each time is the same, and the effect of accurately adjusting the softness degree of the shock absorber 4 can be realized by adjusting the detachable fixation between the first adjusting arm 32 and different first positioning parts 6 by a user.

There are a plurality of gear positions that the damper 4 of the damper structure 200 of the embodiment of the present application can adjust. When the adjusting lever 3 is attached to the swing arm 2, as shown in fig. 5, for example, the length direction of the second adjusting arm 33 is completely coincident with the buffer direction of the shock absorber, the length CD of the second adjusting arm 33 is used to extend the length BC of the shock absorber to the greatest extent, so that the height of the base 1 with respect to the ground is highest, and in order to maintain this state, the first adjusting arm 32 is fixed in alignment with the corresponding first positioning portion 6. The rocker arm 2 is extended to the lowest position at this time, that is, the highest state of the vehicle body when the wheel 100 is grounded. At the moment, the highest ground clearance is provided, and the ground relief obstacle is effectively prevented from rubbing the bottom of the vehicle body and supporting the bottom. Is suitable for driving on off-road pavement.

In fig. 5, arrow F is the elastic force provided by the spring of the shock absorber 4 along the expansion direction of the spring, AO is the arm of force acting on the rotating shaft a, ao≡bo, BD reaches the maximum value at this time, which represents that the vehicle body height is adjusted to the highest position.

It should be noted that, the plurality of first positioning portions 6 need to include the first positioning portion 6 that can correspond to the first adjusting arm 32 when the length direction of the second adjusting arm 33 is completely overlapped with the buffering direction of the shock absorber, so that the scooter can have the highest height of the scooter body, adapt to the driving of the off-road surface, and enrich the drivable road condition of the scooter.

The first adjusting arm 32 is adjusted to the rightmost position as shown in fig. 6, and the length CD of the second adjusting arm 33 is used for increasing the arm AO and reducing the height of the vehicle body. At this time, the arm of force of the damper 4 reaches the maximum state, and the vehicle body height is adjusted to the minimum state. After the ground clearance of the vehicle body is reduced, the gravity center is more stable and safer. Since the arm of force is adjusted to the maximum, the total travel of the shock absorber 4 is the shortest and the hardest, and is suitable for driving on a flat road.

As shown in fig. 7, the first adjusting arm 32 is adjusted to the leftmost state, and a part of the length CD of the second adjusting arm 33 is used to reduce the arm AO, and a part is used to secure a certain vehicle body height. At this time, the arm of force of the damper 4 reaches a minimum state, and the vehicle body height is still in a high state. Because the moment arm is adjusted to the minimum, the total stroke of the shock absorber 4 is longest and the shock absorber is softest, is suitable for running in the state of the maximum fluctuation of the off-road pavement, and can ensure the running comfort.

Of course, the first adjusting arm 32 may be adjusted between the leftmost and rightmost positions according to the driving requirement, so that the adjusting range of the degree of hardness of the damper 4 is wider, and a larger degree of freedom of adjusting the damper 4 is provided for the user.

In some embodiments, referring to fig. 8, two or more connection holes 34 are provided on the second adjusting arm 33 along the length direction of the second adjusting arm 33, and the damper 4 is rotatably connected to any one of the connection holes 34 on the second adjusting arm 33. The connecting position of the shock absorber 4 on the second adjusting arm 33 can be flexibly adjusted, and the arm of force of the shock absorber 4 can be flexibly adjusted, so that the arm of force of the shock absorber 4 can be adjusted through the position change of the first adjusting arm 32, and can be adjusted through the connection of the shock absorber 4 with different connecting holes 34 on the second adjusting arm 33, the adjusting range is wider, the adjusting range of the softness of the shock absorber 4 is larger, and the scooter can be ensured to run on the road surface of more different road conditions.

In some embodiments, referring to fig. 9, a plurality of second positioning portions 7 are provided on a side of the first positioning portion 6 near the main lever 31, the plurality of second positioning portions 7 are provided at intervals along the circumferential direction of the main lever 31, and the first positioning portion 6 and the second positioning portion 7 are staggered in the radial direction of the main lever 31; the first adjusting arm 32 is provided with two connecting holes 34 along the length direction of the first adjusting arm 32, and one connecting hole 34 near the main lever 31 is used for connecting the second positioning part 7. Through setting up second location portion 7, first adjustment arm 32 just can be with first location portion 6 or second location portion 7 detachable connection to make the gear that first adjustment arm 32 can be adjusted more, the gear that the degree of softness of bumper shock absorber 4 was adjusted just more also, makes the regulation of bumper shock absorber 4 finer and smoother.

Specifically, taking the point M, N in fig. 9 as an example, when the mounting pin connecting the first adjusting arm 32 and the first positioning portion 6 is replaced with N from the point M, the first adjusting arm 32 rotates by an angle MDN, and the third hole cannot be punched between the M, N points due to the space requirement of interference between the adjacent first positioning portions 6, so that a finer adjusting effect cannot be generated. But staggers the connection line of M, N points at the positions with different radiuses, and arranges K points, and simultaneously corresponds to one connecting hole 34 on the first adjusting arm 32, which is close to the main rod 31, so that the rotatable smaller-angle adjustment of the first adjusting arm 32 can be completed. In this example, the +_mdk=1/2 +_mdn.

It should be noted that, the second positioning portion 7 and the first positioning portion 6 have the same structure and are both hole structures, so that the first adjusting arm 32 and the second positioning portion 7 can be detachably connected by directly inserting a pin or a screw into the corresponding connecting hole 34 on the second positioning portion 7 and the first adjusting arm 32, which is more convenient for the operation of a common user to adjust the shock absorber 4.

In some embodiments, the distances between two adjacent second positioning portions 7 are equal.
