AI Technical Summary
Existing garage anti-collision devices can only issue collision warnings and cannot buffer or smoothly decelerate vehicles that are about to go out of control, causing vehicles to crash into walls, resulting in damage and personal injury.
The hydraulic buffer-type anti-collision protection mechanism uses components such as polyurethane composite buffer pads, slow rebound sponges, anti-collision beams, and threaded rods to initially absorb, buffer, and disperse the impact force, and finally intercept the vehicle to prevent it from hitting the wall.
It effectively absorbs and disperses vehicle impact forces, preventing serious vehicle damage, and facilitates device disassembly and maintenance, thereby improving safety.

Technical Field
[0001] This utility model belongs to the field of hydraulic impact buffer technology, specifically a hydraulic buffer anti-collision protection mechanism for garage ramps. Background Technology
[0002] This system is designed to prevent vehicles from running off a ramp due to brake failure or operational errors, and uses hydraulic buffering to absorb impact energy, achieving smooth deceleration and stopping.
[0003] Meanwhile, the announcement (CN214463049U) relates to the field of anti-collision devices, including an anti-collision mechanism installed on the rear side wall away from the main opening of the garage and an alarm mechanism located on the inner top surface of the garage. The top surface of the anti-collision mechanism is fixedly equipped with a cutter. The alarm mechanism includes a pressure alarm fixed on the inner top surface of the garage, a rotating rod, a rotating shaft set on one side of the pressure alarm, and a tension spring set between the inner top surface of the garage and the rotating rod. One end of the rotating rod is rotatably connected to the rotating shaft. A pressure block is fixed on the rotating rod near the lower part of the pressure alarm. The upper top surface of the pressure block is inclined. Under the action of the tension spring, the pressure block can make the pressure alarm and the pressure block face to face. A fixing rod is fixed on the side of the rotating shaft away from the pressure alarm. A tension rope for separating the pressure alarm and the pressure block is fixed between the rotating rod and the fixing rod.
[0004] The aforementioned anti-collision devices at garage entrances and exits can only serve as impact alarms; they cannot buffer the impact of vehicles that are about to go out of control or prevent them from slowing down and stopping smoothly, thus causing the vehicles to crash into the walls, resulting in vehicle damage and personal injury during use.
[0005] Therefore, a hydraulic buffer anti-collision protection mechanism for garage ramps is proposed to address the above problems. Utility Model Content

[0013] By adopting the above technical solution, an impact buffering effect can be achieved.

[0018] 1. This utility model uses a polyurethane composite buffer pad and a slow rebound sponge. The polyurethane composite buffer pad can initially absorb the impact pressure and reduce the subsequent impact pressure. The slow rebound sponge can buffer the impact pressure and disperse some of the pressure, thereby stopping and slowing down the vehicle to prevent the impact from being too severe and causing serious damage to the vehicle.

The crash beam and energy-absorbing box can intercept vehicles with excessive impact force to prevent them from hitting the wall. The threaded rod and threaded groove can be quickly disassembled for inspection and repair, preventing the buffer device from failing to relieve impact pressure due to damage.

[0028] An air inlet 3 is provided on the upper left side of the hydraulic cylinder tube 2 to serve as a stretching air intake. An exhaust port 4 is provided on the upper right side of the hydraulic cylinder tube 2 to serve as a squeezing exhaust. A sealing cover 5 is provided on the outer side of the hydraulic rod 6 to prevent leakage. The right end of the sealing cover 5 is fixed to the middle of the left end of the hydraulic cylinder tube 2.
[0029] The steel plate 8 has six threaded grooves 17 at the center of each of its four corners. Each threaded groove 17 has a threaded rod 9 inside it, which serves to facilitate quick disassembly and installation.
[0030] The right end face of the steel plate 8 is fitted with an energy-absorbing box 2 19 in the middle front side, which serves as a support. The right side of the energy-absorbing box 2 19 has a threaded groove 17 in the middle, and the threaded rod 9 rotates in the middle of the energy-absorbing box 2 19 to facilitate quick replacement.
[0031] Energy-absorbing box 18 is attached to the rear side of the right end face of steel plate 8. A threaded groove 17 is opened in the middle of the right side of energy-absorbing box 18, and the threaded rod 9 rotates in the middle of energy-absorbing box 18. An anti-collision beam 16 is provided on the left end face of energy-absorbing box 18 to play an impact buffering role, and the right end face of anti-collision beam 16 is fixed to the left end face of energy-absorbing box 2 19.

[0033] The working principle and process of a hydraulic buffer anti-collision protection mechanism for garage ramps:
[0034] When using the hydraulic body 1 for impact buffering, first install the hydraulic cylinder pipe 2 and hydraulic rod 6, then install the sealing cover 5 to prevent leakage. Next, install the short column 7 in front of the hydraulic rod 6. To intercept vehicles with excessive impact force hitting the wall, a steel plate 8 is installed on the left side of the short column 7. Energy-absorbing boxes 18 and 19 are then installed in the middle of the left side of the steel plate 8 to work with the anti-collision beam 16 to buffer the impact pressure. To further alleviate the impact pressure, a hollow cube 11 is installed on the left side of the steel plate 8, along with a fixing plate 12 on the left side of the hollow cube 11. Then, a slow rebound sponge 15 is set on the left side of the fixed plate 12, and together with the fixed plate 2 14 set on the left side, it will work together to alleviate the impact pressure and absorb and disperse some pressure. We set a polyurethane composite buffer pad 13 for the initial impact buffer, and then the polyurethane composite buffer pad 13 is set on the left side of the fixed plate 2 14. In order to facilitate the inspection and maintenance of the protection device, we opened threaded grooves 17 on the back of the hollow cube 11, the energy absorption box 18, the energy absorption box 2 19 and the steel plate 8 to tighten the threaded rod 9 for fixation and easy disassembly. In order to facilitate tightening, we set a hexagon 10 on the right side of the threaded rod 9.
