As an important facility to ensure the safety of the place and regulate the order of vehicle traffic, the performance and stability of the vehicle access control device are crucial. Efficient and reliable vehicle access control device not only can improve the safety of the place, but also can improve the efficiency of vehicle traffic and reduce traffic congestion. However, with the continuous expansion of application scenarios and the improvement of people's requirements for access control management, the traditional vehicle access control device gradually exposes some shortcomings, prompting the continuous innovation and improvement of related technology.

[0003] At present, in the field of vehicle access control, some traditional access control opening and closing devices adopt relatively complex mechanical structure. For example, some access control systems use chain transmission and multiple gear combination to realize the opening and closing of the door body. Its technical principle is to drive the chain by motor, and the chain drives the gear set to run, so as to make the door body move along the track or rotate around the shaft. Some use hydraulic drive, rely on hydraulic pump to pressurize hydraulic oil into hydraulic cylinder, push piston to move to control the opening and closing of the door body. These traditional structures often involve many mechanical parts, such as chain, chain wheel, gear, piston, hydraulic cylinder, etc.

[0004] However, there is a obvious problem in the prior art, that is, the opening and closing device has many components. The contact area between components increases, which inevitably increases the friction in the long-term operation process. For example, the meshing between chain and chain wheel, gear and gear, and the reciprocating motion of piston in hydraulic cylinder will produce friction. The increase of friction not only leads to energy loss, but also increases the running energy consumption of access control device, and accelerates the wear of components. Frequent wear requires more frequent replacement of components, which increases maintenance cost and maintenance workload. Moreover, with the aggravation of component wear, the running stability of access control device will be affected, which is easy to appear jam, door opening and closing is not smooth and other problems, seriously affecting the normal traffic of vehicle, reducing the practicability of vehicle access control device, therefore a vehicle access control device is proposed to solve the above problems.

[0031] Opening and closing assembly includes electric push rod 7, and the inside fixedly connected with connecting block 8 of electric push rod 7 output end, and connecting block 8 selects steel material, has certain strength and toughness, can stably connect the output end of electric push rod 7 with connecting rod 9, guarantees the effective transmission of power, and the inside slidingly connected with connecting rod 9 of connecting block 8, and connecting rod 9 adopts stainless steel material, and stainless steel has good corrosion resistance and wear resistance, is not easy to rust and wear and tear in the long-term sliding and rotating process, and one end of connecting rod 9 is rotatably connected in the inside of hollow board 2, and the other end of connecting rod 9 is fixedly connected with opening and closing door 3, and opening and closing door 3 generally adopts aluminum alloy or galvanized steel plate material.Aluminum alloy material opening and closing door 3 light in weight, is convenient for electric push rod 7 drive, and has certain corrosion resistance, and the bottom of opening and closing door 3 is provided with blocking component;

[0032] Specifically, when using the vehicle access control device, the operator first starts the electric push rod 7, and the output end drives the connecting block 8 to move. The movement of the connecting block 8 will pull the connecting rod 9 on the inner wall to rotate inside the hollow board 2. With the rotation of the connecting rod 9, it will drive the opening and closing door 3 on the outer wall to rotate accordingly. The rotation of the opening and closing door 3 will further drive the baffle 4 at the bottom to rotate together. Through this mechanical linkage mechanism, precise control of the opening and closing of the opening and closing door 3 is achieved, ensuring that vehicles can smoothly pass through the access control device, improving the automation and safety of the access control system. This design not only improves the efficiency of vehicle passage, but also reduces the error of manual operation, improving the performance and reliability of the entire access control system.

[0033] Reference Figure 1 And Figure 3The blocking assembly comprises a baffle 4 fixedly connected at the top of the bottom of the opening and closing door 3, the bottom of the opening and closing door 3 is fixedly connected with a hollow column 5 made of stainless steel. The stainless steel has excellent corrosion resistance and high strength, and can effectively resist rain in outdoor environment. The hollow column 5 is fixedly connected with a fixed column 10 made of steel inside. The steel has good comprehensive mechanical properties, and has strength and toughness.

[0036] Then when the opening and closing door 3 falls to the ground, the hollow column 5 moves together. Then the movement of the hollow column 5 drives the second sliding column 14 inside to fall to the ground. After being stressed, the second sliding column 14 drives the spring 13 on the outer wall to contract. The contraction of the spring 13 drives the second sliding column 14 and the first sliding column 12 to move inside the hollow column 5, achieving the effect of relieving the impact force when falling to the ground.
