Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a shock absorber with adjustable length. Background Art

[0002] Shock absorbers are used to suppress the shock caused by the rebound of springs after absorbing shock and the impact from the road surface. They are widely used in various vehicles to accelerate the attenuation of frame and body vibrations to improve the vehicle's driving smoothness. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jumping.

[0003] For example, the Chinese patent "CN217977182U" discloses "an adjustable shock absorber for new energy vehicles". The shock absorber has the advantages of good shock absorption effect and easy adjustment by setting a fixed plate, an explosion-proof cylinder, a liquid guide tube, a movable rod, a first spring, a connecting plate, a connecting block, a piston, a support rod, a movable shell, a mounting plate, a damper, a movable sleeve, a connecting rod, a slot, a threaded rod and a block. It solves the problem that the existing shock absorbers usually use springs to absorb shock, the shock absorption effect is poor, the length of the shock absorber cannot be adjusted, and some cars have different chassis heights and can only install specific shock absorbers, which reduces the applicability of the shock absorber. However, when adjusting the height of the shock absorber, the slot needs to be aligned with the block to achieve the adjusted fixation, which is inconvenient in actual operation and increases the difficulty of adjustment.

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a length-adjustable shock absorber, including a damping support 4, two suspension rings 1 respectively arranged at both ends of the damping support 4, a spring 3 arranged between the two suspension rings 1, and also including:

[0022] Two mounting seats 2 are respectively abutted against two ends of the spring 3 and connected to two ends of the damping support 4;

[0023] The first adjusting ring 14 is rotatably provided on the hanging ring 1. The end of the mounting seat 2 is provided with a first threaded portion 5. The first adjusting ring 14 is engaged with the first threaded portion 5. The first adjusting ring 14 is rotated to move the hanging ring 1 away from or close to the mounting seat 2.

[0024] In the embodiment of the utility model, when adjusting the height of the entire shock absorber, the first adjusting ring 14 is directly rotated to drive the rotatably connected lifting ring 1 to move, so that the lifting ring 1 is away from the damping pillar 4 to increase the height of the entire shock absorber, or the lifting ring 1 is close to the damping pillar 4 to reduce the height of the entire shock absorber. It can be suitable for different vehicles and has increased applicability to vehicles with different chassis heights.

[0025] Moreover, after the adjustment is completed, the adjustment of the first adjusting ring 14 can be stopped directly to achieve self-locking under the action of the first threaded portion 5. The operation is simple, and the entire shock absorber can be installed in the vehicle while being steplessly adjusted, and the height of the vehicle can be flexibly adjusted. At the same time, the lifting rings 1 at both ends are provided with the same first adjusting ring 14, and the positions of the lifting rings 1 at both ends can be adjusted synchronously to ensure that the spring 3 is located in the center position of the shock absorber, ensure the structural strength of the entire shock absorber, and improve the shock absorption effect.

[0026] Specifically, Figure 2 As shown, a limit rod 6 is provided at the bottom of the lifting ring 1, and the limit rod 6 is passed through the mounting seat 2 to limit the lifting ring 1. Under the action of the limit rod 6, the mounting seat 2 can be limited, so that when the first adjustment ring 14 is rotated, the lifting ring 1 will only move along the axis direction of the limit rod 6. After the shock absorber is installed on the vehicle, the lifting ring 1 at the end of the shock absorber will not be subjected to the torsion brought by the first adjustment ring 14, and the rubber sleeve in the lifting ring 1 will not be squeezed by the torsion force. In addition, a limit block 7 is provided at the end of the limit rod 6, and the limit block 7 is slidably connected to the mounting seat 2. The movement stroke of the lifting ring 1 can be limited by the limit block 7 to prevent the first adjustment ring 14 from slipping out of the mounting seat 2, and also ensure that the mounting seat 2 and the first adjustment ring 14 have enough contact area for normal buffering.

[0027] Based on the above scheme, if Figure 2As shown, the mounting seat 2 is provided with a second adjusting ring 8, and the mounting seat 2 is also provided with a second threaded portion 9. The second adjusting ring 8 is engaged with the second threaded portion 9 and abuts against the end of the spring 3. Specifically, when in use, the second adjusting ring 8 can be rotated to make the second adjusting ring 8 move on the second threaded portion 9 and squeeze the spring 3, thereby changing the initial length of the spring 3, thereby changing the rebound force of the spring 3. The hardness of the shock absorber can be adjusted according to actual needs. When the vehicle needs to move, the length of the spring 3 can be adaptively shortened to complete the sportiness adjustment of the vehicle. When the vehicle needs to be comfortable, the length of the spring 3 can be adaptively increased to complete the comfort adjustment of the vehicle.

[0028] Specifically, Figure 2 As shown, an auxiliary adjustment ring 13 is fixedly provided on the outer peripheral side of the first adjustment ring 14, and the auxiliary adjustment ring 13 and the second adjustment ring 8 are both provided with a plurality of slots 10. Through the function of the plurality of slots 10, the first adjustment ring 14 or the auxiliary adjustment ring 13 can be adjusted more labor-savingly by using external tools to be snapped into the slots 10, which is convenient for operation.

[0029] Specifically, Figure 1 As shown, the thread rotation direction of the second threaded portion 9 is opposite to that of the first threaded portion 5 , and the strokes of the first adjustment ring 14 and the second adjustment ring 8 can be limited by the first threaded portion 5 and the second threaded portion 9 with opposite rotation directions.

[0030] Specifically, Figure 1 As shown, the first threaded portion 5 is provided with a flat opening 11, and the flat opening 11 is provided with a plurality of graduated grooves 12 along the axial direction of the mounting seat 2. When the first adjustment ring 14 is adjusted, the moving distance of the lifting ring 1 can be known through the corresponding graduated grooves 12, so as to perform precise adjustments for vehicles with different chassis heights.

[0031] In summary, the shock absorber of this solution can adjust the position of the suspension ring 1 by rotating the first adjustment ring 14, and can be completed automatically after the first adjustment ring 14 stops moving, without the need for complex adjustment methods, and the first adjustment ring 14 can be slowly moved on the first threaded portion 5 to achieve stepless adjustment, adapting to the installation of different specifications of chassis heights, and synchronously adjusting the positions of the two suspension rings 1 can ensure that the spring 3 is always in the middle position of the shock absorber, ensuring the structural strength of the entire shock absorber and improving the shock absorption effect. At the same time, the second adjustment rings 8 at both ends of the spring 3 can be adjusted to adjust the initial length of the spring 3 to control the elastic force of the spring 3, and the comfort and sportiness of the vehicle can be switched for easy use. Finally, this solution can change the length of the entire shock absorber by changing the position of the suspension ring 1 and change the length of the spring 3 to change the performance of the entire shock absorber.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
