Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a buffer structure of an automobile shock absorber. Background Art

[0002] The buffer structure of a car shock absorber is an important component inside the shock absorber. Its main function is to provide an additional damping effect when the shock absorber compression stroke is about to end and the shock absorber piston is close to its stroke limit, so as to prevent the internal parts of the shock absorber from being damaged due to impact, while improving ride comfort and vehicle handling. When using a car, people often need to adjust the damping of the buffer structure of the car shock absorber in order to improve comfort or adapt to different driving environments.

[0003] Automobile shock absorbers with adjustable damping often adjust the damping by rotating the adjusting nut. However, the adjusting nut often lacks a corresponding fixing structure. As a result, due to vibration and impact during vehicle driving, the unfixed adjusting nut may become loose, causing the damping setting to change, affecting the vehicle's handling and comfort, and may also increase the risk of accidents during emergency avoidance or high-speed driving.

[0004] In view of this, a buffer structure of an automobile shock absorber is proposed. Utility Model Content

[0025] The buffer structure of the automobile shock absorber of the utility model comprises a first mounting seat 1, a piston rod 2 fixedly connected to the first mounting seat 1 and a threaded rod 4 sleeved on the outside of the piston rod 2, the threaded rod 4 is fixedly connected to the second mounting seat 3 at one end away from the first mounting seat 1, an adjusting block 5 is threadedly connected to the threaded rod 4, a shock-absorbing spring 6 is provided between the adjusting block 5 and the first mounting seat 1, the first mounting seat 1 is rotatably connected to the first mounting block 7, the adjusting block 5 is fixedly connected to the second mounting block 8, the second mounting block 8 is fixedly connected to an elastic telescopic rod 9, the protruding end of the elastic telescopic rod 9 is fixedly connected to a locking head 10, the locking head 10 is slidably connected to two first locking blocks 12, and the locking head 10 is fixedly connected to two second locking blocks 13. A locking groove 11 is provided on the first mounting block 7 for cooperating with the first locking block 12 and the second locking block 13 to lock the first mounting block 7 and the second mounting block 8. That is, the locking head 10 locks the first block and the second mounting block 8 through the first locking block 12 and the second locking block 13.

[0026] Among them, the size of the locking groove 11 is adapted to the size of the locking head 10, the two first locking blocks 12 and the two second locking blocks 13 are symmetrically arranged on both sides of the locking head 10, and the side of the first locking block 12 away from the second locking block 13 and the side of the second locking block 13 away from the first locking block 12 are both inclined. A receiving groove 15 is provided on the locking head 10 for the two first locking blocks 12 to retract inward when passing through the locking groove 11. The two first locking blocks 12 are slidably connected in the receiving groove 15, as shown in FIG. Figure 5 Locking, when the distance between the first locking block 12 and the second locking block 13 is the same as the thickness of the first mounting block 7.

[0027] Specifically, both sides of the two first locking blocks 12 are fixedly connected with a first slider 14 with a T-shaped cross-section, and a first sliding groove 141 for the sliding of the first slider 14 is opened in the storage groove 15. A second spring 16 is fixedly connected between the two first locking blocks 12. After the protruding end of the elastic telescopic rod 9 is pulled downward, when the first locking block 12 moves to the locking groove 11, the first locking block 12 will be retracted toward the storage groove 15 under the action of the inclined surface until it passes the locking groove 11 and pops out to lock and limit.

[0028] In addition, the elastic telescopic rod 9 includes a main rod 91 fixedly connected to the second mounting block 8 and a sub-rod 92 slidably arranged in the main rod 91, two limit blocks 93 are fixedly connected to the sub-rod 92, and a limit groove 94 that is adapted to the size of the limit block 93 is provided on the main rod 91. A first spring 95 is fixedly connected to the bottom of the sub-rod 92, one end of the first spring 95 is fixedly connected to the sub-rod 92, and the other end of the first spring 95 is fixedly connected to the bottom wall of the cavity of the main rod 91. The limit block 93 and the limit groove 94 are used to prevent the sub-rod 92 from rotating relative to the main rod 91.

[0029] like Figure 3 As shown, an arc-shaped slider 17 with a T-shaped cross-section is fixedly connected to the first mounting block 7, and an annular groove 18 that is adapted to the size of the arc-shaped slider 17 is provided on the first mounting seat 1. The annular groove 18 is used to enable the first mounting block 7 to rotate along the first mounting seat 1. In the specific setting, an adjusted locking component, such as a card strip or a card block, can be provided between the annular groove 18 and the arc-shaped slider 17 to prevent the adjusted arc-shaped slider 17 from rotating.

[0030] When using this device, the damping of the shock-absorbing spring 6 is adjusted by rotating the adjusting block 5. After the adjustment is completed, the first mounting block 7 is rotated to the bottom of the second mounting block 8, and then the auxiliary rod 92 is pulled to lock the locking head 10 and the first mounting block 7. At this time, the first spring 95 is in a stretched state, but since the first limit block 93 is limited by the locking groove 11, the first mounting block 7 and the second mounting block 8 will be tightened to prevent the adjusted adjusting block 5 from moving.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
