[0033] Figure 1 The utility model discloses a shock absorber buffer support structure's perspective structure schematic diagram is shown. Figure 2 The utility model discloses a shock absorber buffer support structure's perspective structure schematic diagram is shown. Figure 3 The utility model discloses a shock absorber buffer support structure's perspective structure schematic diagram is shown. Figure 4The utility model discloses a shock absorber buffer support structure, and the main view structure schematic drawing of transmission mechanism is shown when the driven gear moves to the first sector gear from the second sector gear. Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the shock absorber buffer support structure includes base 1, swing arm 2, transmission mechanism 5 and eccentric mechanism 6. Swing arm 2, swing arm 2 is hinged base 1. Eccentric mechanism 6, connect driven gear 55 and swing arm 2. The torque output by drive mechanism 4 is converted into the reciprocating swing of swing arm 2 through eccentric mechanism 6, and then the shock absorber 7 is stretched and compressed. Drive mechanism 4 is continuously operated to continuously stretch and compress shock absorber 7, and the durability detection of shock absorber 7 is performed. Transmission mechanism 5, transmission mechanism 5 includes meshing driving gear 51 and driven gear 55. Driving gear 51 is spliced by first sector gear 511 and second sector gear 513. Second sector gear 513 is arranged in the sector gap 512 of the first sector gear 511. The first sector gear 511 is connected with the drive mechanism 4. When the driven gear 55 meshes with the first sector gear 511, the drive mechanism 4 drives the swing arm 2 to swing through the first sector gear 511 and the driven gear 55. And the second sector gear 513 is not directly connected with the drive mechanism 4, when the driven gear 55 meshes with the second sector gear 513, the torque of the drive mechanism 4 cannot be transmitted to the torque, and then the drive mechanism 4 is simulated to stop. Through the setting of the first sector gear 511 and the second sector gear 513, the drive mechanism 4 can be continuously operated to stop driving the shock absorber 7 periodically, avoid the frequent start and stop of the shock absorber 7, thereby prolonging the service life of the drive mechanism 4, ensuring the working efficiency of the drive mechanism 4, and avoiding the energy loss caused by frequent start and stop. Wherein, along the rotation direction of the driving gear 51, the first sector gear 511 and the second sector gear 513 are connected by the spring 53. The two ends of the shock absorber 7 are connected with the base 1 and the swing arm 2 respectively. After the driven gear 55 is separated from the second sector gear 513, the spring 53 drives the second sector gear 513 to reset, so that when the driven gear 55 is transitioned from the first sector gear 511 to the second sector gear 513, the first sector gear 511 and the second sector gear 513 are attached, and the driven gear 55 is transitioned from the first sector gear 511 to the second sector gear 513 more smoothly.

[0034] In the embodiment, the drive mechanism 4 can be a motor.

[0035] Please refer to Figure 2 、 Figure 3 and Figure 4The first sector gear 511 is fixedly arranged on the first rotating shaft 52. The second sector gear 513 is rotatably arranged on the first rotating shaft 52. The driving mechanism 4 is connected to the first rotating shaft 52. When the driven gear 55 engages the second sector gear 513, the second sector gear 513 rotates around the first rotating shaft 52. At this time, the second sector gear 513 and the driven gear 55 cannot transmit torque, simulating the shutdown of the driving mechanism 4.

[0036] Preferably, the second sector gear 513 comprises a hub 514 and a rim 516. The hub 514 is sleeved on the first rotating shaft 52. The rim 516 is bent between the hub 514, so that the hub 514 and the first sector gear 511 are in the same plane. When the second sector gear 513 rotates around the first rotating shaft 52 and abuts against the first sector gear 511, the second sector gear 513 can no longer rotate around the first rotating shaft 52. At this time, the second sector gear 513 and the driven gear 55 can transmit torque, and the driven gear 55 can smoothly transition from the second sector gear 513 to the first sector gear 511, improving the stability of the transmission mechanism 5. The hub 514 extends circumferentially to form a limiting disc 515. The limiting disc 515 contacts the driving gear 51, increasing the contact area between the second sector gear 513 and the first sector gear 511, thereby enhancing the stability of the second sector gear 513 around the first rotating shaft 52.

[0037] More preferably, a shaft sleeve 54 is arranged on the first rotating shaft 52, and the hub 514 is arranged between the shaft sleeve 54 and the first sector gear 511. The position of the second sector gear 513 on the first rotating shaft 52 is limited by the shaft sleeve 54.

[0038] Please refer to the drawings and Figure 2 The transmission mechanism 5 and the eccentric mechanism 6 are arranged in the housing 3. By including the transmission mechanism 5 and the eccentric mechanism 6 in the housing 3, foreign objects in the transmission mechanism 5 and the eccentric mechanism 6 are reduced, prolonging the service life of the shock absorber buffer support structure.

[0039] Preferably, the driven gear 55 is arranged on the second rotating shaft 56. The second rotating shaft 56 is rotatably connected to the housing 3. The first rotating shaft 52 is also rotatably connected to the housing 3. The transmission mechanism 5 and the eccentric mechanism 6 are supported by the housing 3.

[0040] Please refer to Figure 1 and Figure 2 The eccentric mechanism 6 comprises an eccentric wheel 61 and a crank 62. The crank 62 is eccentrically connected to the eccentric wheel 61. The eccentric wheel 61 and the driven gear 55 are coaxially arranged. One end of the crank 62, which is eccentric to the eccentric wheel 61, is rotatably connected to the swing arm 2. When the driving mechanism 4 drives the eccentric wheel 61 to rotate along the transmission mechanism 5, the eccentric wheel 61 drives the crank 62 to reciprocate, thereby driving the shock absorber 7 to compress and rebound.

[0041] Preferably, a lower hinge seat 11 is arranged on the base 1. An upper hinge seat 21 is arranged on the swing arm 2. The upper hanger ring 71 of the shock absorber 7 is hinged to the upper hinge seat 21 through the fastening bolt 12. The lower hanger ring 72 of the shock absorber 7 is hinged to the lower hinge seat 11 through the fastening bolt 12. The rotary connection between the shock absorber 7 and the base 1, and the rotary connection between the shock absorber 7 and the swing arm 2 are realized.

[0042] The specific working process of the utility model is as follows:

[0043] When the shock absorber 7 is subjected to durability detection, first, the lower hanger ring 72 and the lower hinge seat 11 are rotatably connected through the fastening bolt 12, and the upper hanger ring 71 and the upper hinge seat 21 are rotatably connected through the fastening bolt 12. Then, the driving mechanism 4 is started, and the driving mechanism 4 outputs torque to drive the first rotating shaft 52 to rotate, and the rotating first rotating shaft 52 drives the first sector gear 511 to rotate synchronously. At this time, the driven gear 55 meshing with the first sector gear 511 is driven to rotate by the first sector gear 511, and in turn drives the second rotating shaft 56 and the eccentric wheel 61 connected with the driven gear 55 to rotate. The rotating eccentric wheel 61 drives the crank 62 to reciprocate, and in turn drives the swing arm 2 connected with the crank 62 to swing. The swinging swing arm 2 drives the shock absorber 7 to compress and rebound. Until the driven gear moves from the first sector gear 511 to the second sector gear 513, the second sector gear 513 rotates around the first rotating shaft 52, at this time, the driven gear stops rotating and no longer drives the swing arm 2 to swing. Until the rim 516 of the second sector gear 513 abuts against the first sector gear 511, the second sector gear 513 is limited to rotate by the first sector gear 511, and the driving mechanism 4 outputs torque to the shock absorber 7 along the first rotating shaft 52, the second sector gear 513, the driven gear 55, the second rotating shaft 56, the eccentric and the swing arm 2. Then, with the relative rotation between the driven gear 55 and the second sector gear 513, the driven gear 55 moves to the first sector gear 511 again. At this time, the spring 53 drives the second sector gear 513 to rotate around the first rotating shaft 52, and the second sector gear 513 is reset. The meshing action between the driving gear 51 and the driven gear 55 is repeated, and the driving mechanism 4 continues to operate, which can also simulate the action of stopping the driving mechanism 4.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.
