The spring is a key component of the chassis suspension system, and its working principle is to support the mass of the car body. When the car is stationary, the spring is in a static position; when driving, the spring is compressed or rebounded with the ups and downs of the road surface, converting the ups and downs of the road surface into acceptable body vibration.

[0003] As shown in the application document with the prior art announcement number CN213799146U, it includes a base plate, a driving wheel module, a shock absorbing module, and a guide module. The guide rails, sliders, and shock absorbers in the guide module are arranged vertically in parallel; the motor mounting flange in the driving wheel module and the lower end of the guide rail fixing plate in the guide module are fixed together by screws, the driving module is connected to the lower end of the shock absorber, the base plate is connected to the upper end of the shock absorber, and the slider fixing plate in the guide module is fixed to the bottom of the base plate by screws. This technical solution adopts the method of the joint action of the guide rail, slider and shock absorber, which not only solves the disadvantages of the indoor AGV shock absorption system with small shock absorption stroke and poor impact resistance; compared with the independent suspension chassis, this technical solution has the advantages of good shock absorption effect, waterproof and dustproof, compact layout, high space utilization, adaptability to outdoor harsh environment requirements, simple structure, and easy installation.

[0004] However, the structure of the above technical solution is relatively complicated, and the spring is exposed to the outside, which causes the adhesion of external impurities such as dust and rainwater to corrode and damage the spring, thereby affecting the performance of the spring.

[0025] like Figure 1-5 As shown, the buffer assembly includes a mounting bracket 3 arranged at the bottom of the chassis seat 1, the mounting bracket 3 is arranged on the side of the driving wheel 2 close to the chassis seat 1, a screw 4 is arranged at the bottom end of the mounting bracket 3, the top end of the screw 4 passes through the mounting bracket 3 and extends to the inside of the chassis seat 1, the outer wall of the screw 4 is threadedly connected to the chassis seat 1 and the mounting bracket 3, the top end of the screw 4 is externally sleeved with a spring 5 and a movable part 6, the movable part 6 is arranged at the bottom of the spring 5; the spring 5 is externally sleeved with a telescopic tube 7, the top and bottom ends of the telescopic tube 7 are both installed with connecting rings 8, the two connecting rings 8 are both threadedly connected with fixing rings 9, and the two fixing rings 9 are respectively installed on the movable part 6 and the side of the chassis seat 1 close to the telescopic tube 7.

[0026] As shown in 4 and 6, a connecting shaft 10 is installed on the side of the driving wheel 2 close to the movable part 6, and the end of the connecting shaft 10 away from the driving wheel 2 is movably connected to the movable part 6 through a bearing; an active cavity 11 is opened inside the end of the movable part 6 close to the driving wheel 2, and a motor 12 is installed inside the active cavity 11, and the output shaft of the motor 12 passes through the movable part 6 and is fixed to the connecting shaft 10. The connecting shaft 10 is driven to rotate by the motor 12, and the connecting shaft 10 then synchronously drives the driving wheel 2 to rotate, thereby realizing the movement of the chassis seat 1, and dustproof nets 13 are embedded on the front and rear sides of the movable part 6. Through the setting of the dustproof net 13, dust in the air can be blocked to prevent dust from flowing into the active cavity 11 with air, and to prevent dust from adhering to and affecting the performance of the motor 12.

[0027] like Figure 4 As shown, sliders 14 are installed on both sides of the front and rear ends of one end of the movable part 6 close to the mounting bracket 3, and a slide groove 15 is provided on one side of the mounting bracket 3 close to the slider 14.
