[0043] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] See also Figures 1 to 4 , an inflatable tunnel parking area side wall anti-collision device, comprising:

[0045] Base 1, which is used to be installed on the side wall of the tunnel parking area;

[0046] a support plate 2 mounted on the front side wall of the base 1 via a fixing mechanism, wherein the fixing mechanism includes telescopic brackets 3 provided on both sides of the front side wall of the base 1, with the ends of the telescopic brackets 3 connected to the opposite side walls of the base 1 and the support plate 2, respectively;

[0047] An inflatable cushion 7 is provided on one side of the base 1 close to the support plate 2. An air pump 6 is also provided on the support plate 2.

[0049] The support plate 2 is also provided with a sensing device 8 and a control system 9. The sensing device 8 is used to monitor the vehicle's movement status and transmit the status information to the control system 9. The control system 9 can control the start and stop of the air pump 6 based on the information. The control system 9 includes a controller, a power supply, and a data processing module. The controller is used to receive signals sent by the sensing device and control the start and stop of the air pump 6 based on the signals. The power supply provides the required power to the control system and the air pump 6. The data processing module is used to process the data from the sensing device to ensure that the device can respond in real time and provide effective protection.

[0050] In the present invention, the control system 9 receives data from the sensing device 8 and calculates and analyzes the speed and distance of the vehicle. When the vehicle speed exceeds the set value or the distance between vehicles is too close, the control system 9 sends relevant control information to the air pump 6 control device, thereby starting the air pump 6 to quickly inflate the air cushion 7. When the vehicle hits the anti-collision plate 5, the anti-collision plate 5 can effectively guide the force of the vehicle's impact to the sides, reducing the force of the frontal impact. Therefore, through the combined action of the shock absorbing device 4 and the air cushion 7, a buffer zone is formed, providing timely protection, so that the impact force gradually dissipates, thereby achieving effective shock absorption and buffering effects, and reducing damage to the vehicle and personnel. The sensing device 8 includes an infrared sensor and a distance sensor, which can monitor the vehicle's motion status in real time; the control system 9 includes a central processing unit and a control module, which can process sensor data and issue control instructions according to a preset program.

By setting the second support plate 451, the third support plate 452 and the third slider 455, the support column 453 transmits the impact force to the third support plate 452, and the third support plate 452 squeezes the connecting rod 457 downward, so that the third slider 455 on the connecting rod 457 squeezes the second spring 456 inward. The second spring 456 produces a shock-absorbing effect during the contraction process, thereby achieving a second shock-absorbing effect.

[0056] Preferably, there are four shock-absorbing components, which are respectively arranged at the four corners between the support plate 2 and the anti-collision plate 5, so as to make the anti-collision plate 5 more stable and avoid tilting.

The inner bottom wall of the movable groove 11 is movably provided with a first tooth block 12. One side of the first tooth block 12 is fixedly connected to one side of the T-shaped slider 322. The inner top wall of the movable groove 11 is fixedly provided with a first rack 13 that meshes with the first tooth block 12. The power switch of the electromagnet 325 is electrically connected to the control system 9.

[0060] In this embodiment, when the vehicle collides with the anti-collision plate 5, the control system 9 controls the electromagnet 325 to be energized, and then the electromagnet 325 is energized to attract the magnet 324, driving the T-shaped slider 322 to slide upward in the T-shaped groove 321, thereby causing the first tooth block 12 to engage with the first rack 13, so that the first slider 32 is fixed in the first slide groove 31, thereby cooperating with the inflatable cushion 5 to absorb the impact force, thereby achieving a shock absorption effect, and at the same time protecting the inflatable cushion 5 from being damaged.

[0061] Preferably, the base 1 is a rectangular plate-like structure with multiple fixing holes on its bottom. It is fixed to the side wall of the tunnel parking area with bolts or expansion bolts to ensure that the device does not move or tilt during operation. The upper surface of the base 1 is provided with multiple mounting holes for installing various components, facilitating assembly and maintenance of the device.

[0062] Preferably, the anti-collision plate 5 is a curved plate that protrudes toward the side away from the base 1 , which can effectively guide the force of the vehicle collision to disperse to both sides, thereby reducing the force of the frontal collision.
