Description

Technical Field

[0001] The present application relates to the field of anti-collision buffer vehicles, and more specifically, to a stable anti-collision device and an anti-collision buffer vehicle. Background Art

[0002] The anti-collision buffer vehicle is one of the important tools used in road protection to protect the safety of personnel during road protection. The structure of the anti-collision buffer vehicle includes a moving vehicle body and an anti-collision device. The anti-collision device is installed at the rear end of the moving vehicle body and can be driven by an oil cylinder installed on the moving vehicle body to flip up and down relative to the moving vehicle body. During use, the oil cylinder drives the protection device to flip to a horizontal state. When a vehicle hits the buffer vehicle from behind, the anti-collision device provides buffering to the moving vehicle body to reduce the harm to construction workers.

[0003] When using the anti-collision buffer vehicle, the anti-collision device is installed on the tail of the vehicle body to relieve the impact force. However, a tailgate is provided at the tail of the vehicle body. During daily use, the tailgate needs to be opened frequently to facilitate loading and unloading of goods. However, the existing anti-collision device is likely to affect the opening and closing of the tailgate, resulting in the anti-collision device affecting the daily use of the vehicle body. At the same time, the existing anti-collision device has a poor impact mitigation effect. For this reason, we propose a stable anti-collision device and an anti-collision buffer vehicle. Summary of the Utility Model

[0004] To make up for the above deficiencies, the present application provides a stable anti-collision device and an anti-collision buffer vehicle, aiming to improve the problems that the anti-collision device is likely to affect the opening and closing of the tailgate and has a poor buffering effect.

[0005] In a first aspect, an embodiment of the present application provides a stable anti-collision device, including a lifting mechanism. The lifting end of the lifting mechanism is connected to a mounting plate. A plurality of buffer components are installed on the side wall of the mounting plate. One end of the plurality of buffer components is connected to the same anti-collision plate. A plurality of protective rods are connected between the anti-collision plate and the mounting plate, and anti-collision tires are also installed on its front surface.

[0006] In a specific implementation, the lifting mechanism includes two hydraulic cylinders. The output shafts of the two hydraulic cylinders are both fixedly connected to lifting blocks. Both lifting blocks are fixedly connected to the side wall of the mounting plate.

[0007] In a specific implementation, the buffer component includes a buffer airbag fixedly installed on the front surface of the mounting plate. One end of the buffer airbag is provided with a telescopic member. One end of the telescopic member is fixedly connected to the back surface of the anti-collision plate.

[0008] In a specific embodiment, the telescopic member includes a connecting plate fixedly installed on the buffer airbag. One end of the connecting plate is fixedly installed with a buffer spring, and one end of the buffer spring is fixedly connected to the back surface of the anti-collision plate.

[0009] In a specific embodiment, several of the protective rods are all bent, and they are all bent towards the outside of the anti-collision plate.

[0010] In a specific embodiment, a chute is formed on the back surface of the mounting plate.

[0011] In a second aspect, the present application further provides an anti-collision buffer vehicle, including

[0012] the above-mentioned stable anti-collision device; and

[0013] a vehicle body, support blocks are fixedly installed on the side walls at both ends of the vehicle body, and two hydraulic cylinders are respectively fixedly installed on the two support blocks.

[0014] In a specific embodiment, a limiting block is fixedly installed at one end of the vehicle body's cargo box. The mounting plate is in contact with the vehicle body's cargo box, and the chute is sleeved on the limiting block.

[0015] The beneficial effects of the present application: By installing a lifting mechanism on the vehicle body, an installation plate is arranged on the lifting mechanism, and several buffer components are installed on the side wall of the installation plate. The buffer components can relieve the impact force.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0023] Please refer to Figures 1-3 , the present application provides a stable anti-collision device, including a lifting mechanism 10. The lifting end of the lifting mechanism 10 is connected with a mounting plate 20. A plurality of buffer assemblies 30 are installed on the side wall of the mounting plate 20. One end of the plurality of buffer assemblies 30 is connected to the same anti-collision plate 40. A plurality of protective rods 50 are connected between the anti-collision plate 40 and the mounting plate 20, and an anti-collision tire 60 is also installed on its front. Specifically, in order to prevent affecting the opening of the rear door of the vehicle body 70 and the dumping of goods, the lifting mechanism 10 is installed on the vehicle body 70, so that the lifting mechanism 10 can drive the mounting plate 20 to move upward, so that the mounting plate 20 moves above the vehicle body 70. At the same time, when the anti-collision plate 40 is impacted, the anti-collision tire 60 can play a preliminary buffering role. When the anti-collision plate 40 is stressed, it will squeeze the protective rod 50 and deform it. During the deformation process of the protective rod 50, the anti-collision plate 40 will also squeeze the buffer assembly 30, so as to improve the anti-collision effect.

[0024] Refer to Figure 1 , the lifting mechanism 10 includes two hydraulic cylinders 110. The output shafts of the two hydraulic cylinders 110 are both fixedly connected with lifting blocks 120. The two lifting blocks 120 are both fixedly connected with the side wall of the mounting plate 20. When setting, the hydraulic cylinder 110 drives the lifting block 120 to move, so as to realize the two lifting blocks 120 driving the same mounting plate 20 to move, thereby preventing affecting the dumping process of goods.

[0025] Refer to Figure 2, the buffer assembly 30 includes a buffer airbag 310 fixedly installed on the front surface of the mounting plate 20. One end of the buffer airbag 310 is provided with a telescopic member 320, and one end of the telescopic member 320 is fixedly connected to the back surface of the anti-collision plate 40. Specifically, the buffer airbag 310 is installed on the mounting plate 20, and the buffer airbag 310 can relieve the impact force. At the same time, in cooperation with the telescopic member 320, the anti-collision ability is improved.

[0026] Refer to Figure 2 , the telescopic member 320 includes a connecting plate 3210 fixedly installed on the buffer airbag 310. One end of the connecting plate 3210 is fixedly installed with a buffer spring 3220, and one end of the buffer spring 3220 is fixedly connected to the back surface of the anti-collision plate 40. It should be noted that after the anti-collision plate 40 is impacted, it will squeeze the buffer spring 3220 to achieve the purpose of several buffer springs 3220 relieving the impact force. At the same time, during the compression process of the buffer spring 3220, it will squeeze the buffer airbag 310 through the connecting plate 3210, so as to achieve the purpose of cooperating to relieve the impact force.

[0027] Refer to Figure 2 , several protective rods 50 are all bent, and they are all bent towards the outside of the anti-collision plate 40. A chute 210 is opened on the back surface of the mounting plate 20. Specifically, the protective rods 50 are bent towards the outside, so that after the anti-collision plate 40 is impacted, it will squeeze several protective rods 50, causing the protective rods 50 to deform and continue to bend outwards to achieve the purpose of relieving the impact force.

[0028] Refer to Figure 4 , an anti-collision buffer vehicle, including

[0029] the above-mentioned stable anti-collision device; and

[0030] a vehicle body 70. Support blocks 710 are fixedly installed on both side walls at both ends of the vehicle body 70. Two hydraulic cylinders 110 are respectively fixedly installed on the two support blocks 710. A limit block 720 is fixedly installed at one end of the hopper of the vehicle body 70. The mounting plate 20 is in contact with the hopper of the vehicle body 70, and the chute 210 is sleeved on the limit block 720. Specifically, the mounting plate 20 slides on the limit block 720 to achieve the purpose of limiting the mounting plate 20 and improving the stability of the mounting plate 20 during the lifting process. The two support blocks 710 are respectively installed on the side walls at both ends of the vehicle body 70 to achieve the purpose of supporting the hydraulic cylinders 110.

[0031] When the stable anti-collision device and the anti-collision buffer vehicle are in use: When it is necessary to open the tailgate of the rear truck bed of the vehicle body 70, two hydraulic cylinders 110 are activated, causing two lifting blocks 120 to drive the same mounting plate 20 upward. Further, the mounting plate 20 is moved above the truck bed of the vehicle body 70, and then the tailgate can be opened. When the rear part of the vehicle body 70 is impacted, the anti-collision plate 40 will squeeze a number of protective rods 50, causing the number of protective rods 50 to bend to relieve the impact force. At the same time, the anti-collision plate 40 will squeeze the buffer spring 3220, causing the buffer spring 3220 to compress and relieve the impact force. The buffer spring 3220 squeezes the buffer airbag 310 through the connecting plate 3210, thereby realizing cooperation and improving the overall buffer effect.

[0032] It should be noted that the specific model and specification of the hydraulic cylinder 110 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method uses the existing technology in this field, so it will not be described in detail here.
