The guide blocks are located inside the guide groove and are movably connected to it.
[0010] As an improved technical solution, the two sets of buffer plates are fixedly connected at the ends away from the shell by a connecting plate. The connecting plate is provided in two sets, which intersect each other and form an X shape.
[0011] As an improved technical solution, the inner side of the buffer support is provided with a base plate, the base plate is located between two sets of lifting members, both ends of the base plate are fixedly connected to the buffer support, a lower shell is fixedly connected to the surface of the base plate, an upper shell is provided on the top of the lower shell, one end of the upper shell is located inside the lower shell and is fixedly connected to it, and a compression spring is fixedly connected inside the lower shell.

[0030] like Figures 1 to 6 As shown in the figure, this embodiment provides a car buffer device, which includes a buffer support 1, a support plate 2 on the top of the buffer support 1, and an inclined groove 101 on the bottom of the buffer support 1. There are two sets of inclined grooves 101 that correspond to each other, and a lifting member is provided on the inner side of the buffer support 1.
[0031] The lifting component includes an electric push rod 3 located inside the buffer support 1. The output end of the electric push rod 3 is fixedly connected to a drive block 4. The surface of the drive block 4 is in the shape of an inclined surface 5. The inclined surface 5 is located at the bottom of the inclined groove 101 and fits against it. The bottom of the drive block 4 is equipped with moving wheels 6, which are evenly distributed at the bottom of the drive block 4. The lifting component is provided in two sets, which correspond to each other and correspond to the inclined groove 101. The lifting component is located inside the shaft pit, and the buffer support 1 is located inside the shaft pit and fits against its inner side. The height of the buffer support 1 can be adjusted by setting the lifting component. By lowering the buffer support 1, it can be moved away from the bottom of the car, avoiding the car from contacting the buffer structure and thus easily triggering its movement. In addition, by raising the buffer support 1, it is convenient to inspect and maintain the buffer structure.
[0032] A housing 7 is fixedly connected to the inner side of the buffer support 1. The housings 7 are evenly distributed at the four corners of the buffer support 1 and are inclined at 45 degrees. A slide rod 8 is fixedly connected inside the housing 7. A buffer spring 9 is sleeved on the surface of the slide rod 8. A buffer plate 10 is fixedly connected to the top of the buffer spring 9. The bottom of the buffer spring 9 is fixedly connected to the housing 7. The buffer plate 10 can drive the operation of the buffer spring 9, thereby achieving the purpose of buffering. At the same time, the slide rod 8 can also give the buffer spring 9 a guiding force, preventing it from getting tangled when squeezed.
[0033] One end of the buffer plate 10 extends to the outside of the housing 7. A guide groove 701 is provided on the inner side of the housing 7. Guide blocks 1001 are fixedly connected to both sides of the buffer plate 10. The guide blocks 1001 are located inside the guide groove 701 and are movably connected to it, which can ensure the stability of the buffer plate 10 when it is raised and lowered, and prevent it from getting stuck on the surface of the slide bar 8.
[0034] The two sets of corresponding buffer plates 10 are fixedly connected at the ends away from the housing 7 by connecting plates 11. There are two sets of connecting plates 11, which cross each other and form an X shape, which can more evenly disperse the impact force of the car.
[0035] The inner side of the buffer support 1 is provided with a base plate 12, which is located between two sets of lifting members. Both ends of the base plate 12 are fixedly connected to the buffer support 1. A lower shell 13 is fixedly connected to the surface of the base plate 12. An upper shell 14 is provided on the top of the lower shell 13. One end of the upper shell 14 is located inside the lower shell 13 and is fixedly connected to it. A compression spring 15 is fixedly connected inside the lower shell 13.
[0036] An extrusion block 16 is movably connected inside the upper shell 14. A bearing plate 17 is provided on the top of the upper shell 14. The extrusion block 16 passes through the upper shell 14, and its two ends are fixedly connected to the compression spring 15 and the bearing plate 17, respectively. The bearing plate 17 is located at the bottom of the connecting plate 11 and is fixedly connected to it. It can provide buffering force for the central part of the connecting plate 11, and avoid the connecting plate 11 relying solely on the buffering structure at the four corners of the buffer support 1 for buffering, thereby evenly dispersing the impact force of the car.
[0037] The inner side of the support plate 2 is fixedly connected to the force plate 18 and the first guide rod 19. The force plate 18 is cross-shaped, and the first guide rod 19 is evenly distributed at the four corners of the support plate 2. The end of the first guide rod 19 away from the support plate 2 is fixedly connected to the buffer plate 10 and the connecting plate 11.
[0038] A second guide rod 20 is fixedly connected to the bottom of the force plate 18. The bottom of the second guide rod 20 is fixedly connected to the connecting plate 11, which can prevent the car from directly contacting the buffer spring 9 and the compression spring 15, thereby extending the service life of the buffer spring 9 and the compression spring 15, and at the same time, it can make the impact force of the car more evenly distributed.
[0039] In use, the electric push rod 3 can be activated to retract, causing the drive block 4 to move towards the electric push rod 3. The inclined surface 5 of the drive block 4 slowly separates from the buffer support 1. As the drive block 4 separates and due to its own weight, the buffer support 1 slowly contacts the surface of the pit until one end of the drive block 4 is completely disconnected from the inclined groove 101, and the buffer support 1 is in complete contact with the ground. This increases the distance between the buffer support 1 and the car, thus preventing the pressure generated by personnel walking from causing the car to contact the buffer structure and trigger its operation, thereby improving the comfort of personnel.
[0040] Conversely, the electric push rod 3 can be activated to push the drive block 4 towards the inclined groove 101, so that it slowly lifts the buffer support 1, which can facilitate the maintenance of the buffer structure by the staff and thus improve work efficiency.
[0041] When the car is damaged and falls, it will directly contact the support plate 2. The force plate 18 can strengthen the support plate 2 and distribute the impact force of the support plate 2. When the support plate 2 is impacted, it will descend through the first guide rod 19 and the second guide rod 20, causing the connecting plate 11 to descend as a whole. During the descent, the connecting plate 11 will drive the buffer plate 10 to slide down along the surface of the slide rod 8 and compress the buffer spring 9 to deform it, thereby achieving the purpose of dispersing the impact force.
[0042] Simultaneously, when the connecting plate 11 descends, it also disperses the impact force to the extrusion block 16 through the bearing plate 17. As it descends, the compression spring 15 is compressed and deformed, thus dispersing the impact force at the center of the connecting plate 11. When used in conjunction with the buffer spring 9, the impact force can be dispersed more evenly, improving the overall buffering effect. Furthermore, through the combined use of the first guide rod 19, the second guide rod 20, the extrusion block 16, the connecting plate 11, and the force-bearing plate 18, the impact force of the car can be prevented from directly contacting the buffer spring 9 and the compression spring 15, making the stress and wear of both more even, thereby increasing their service life.
[0043] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
