Description

Technical Field

[0001] This utility model belongs to the field of barrier gate technology, and specifically relates to a buffer mechanism for vehicle entry and exit barriers. Background Technology

[0002] A barrier gate, also known as a vehicle barrier, is an electromechanical integrated device used to control the entry and exit of vehicles. Widely used in parking lots, residential entrances and exits, toll stations, and other scenarios, it is one of the core facilities for intelligent security and traffic management. Its core structure includes a housing, motor, gearbox, transmission mechanism, gate arm, and control system. The motor drives the gate arm to rise, fall, or fold, thus enabling the passage and interception of vehicles. Modern barrier gates often integrate intelligent technologies and can be linked with systems such as license plate recognition, IC card reading and writing, and Bluetooth recognition, supporting automatic recognition and passage without manual operation. Based on the gate arm type, they can be divided into straight-arm barrier gates, curved-arm barrier gates, and fence barrier gates, adapting to different widths and environmental requirements. They feature rapid response, stable operation, and security protection (such as obstacle detection and rebound), playing a crucial role in regulating vehicle traffic order and improving management efficiency.

[0003] There are two types of barrier gates: those that can automatically identify passing vehicles and those that cannot. Barrier gates that can automatically identify passing vehicles can automatically lift when a vehicle is run over, while those that cannot require manual control. When a barrier gate that can automatically identify vehicles runs over a vehicle, it is easy to damage the vehicle because the surface of a traditional barrier gate does not have a buffer protection structure, thus causing certain property damage. Utility Model Content

[0004] The purpose of this utility model is to provide a buffer mechanism for vehicle entry and exit gates, which has the advantage of preventing damage to vehicles when the gate presses on them.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a vehicle entry / exit gate buffer mechanism, including a gate arm, a plurality of main mounting seats rotatably connected to the surface of the gate arm, a secondary mounting seat provided on one side of the main mounting seats, a plurality of fixing screws threadedly connected to one side of the main mounting seats and the secondary mounting seats, a plurality of spring push rods bolted to the surface of both the main mounting seats and the secondary mounting seats, and an arc-shaped plate bolted to the piston end of each corresponding spring push rod, the arc-shaped plate providing a buffering effect through the spring push rods, and when the gate arm contacts the vehicle, the spring push rods can offset the impact force to protect the gate arm and the vehicle.

[0006] In summary, this utility model has the following beneficial effects: 1. To address the problem of dual damage to both equipment and vehicle caused by direct impact between existing barrier gate arms and vehicles (especially the roof of taller vehicles) due to misoperation or improper vehicle positioning, this utility model incorporates a buffer structure on the barrier arm consisting of an arc-shaped plate, spring push rods, and mounting seats. Several main mounting seats and their corresponding auxiliary mounting seats are rotatably connected to the barrier arm, and several spring push rods are bolted to multiple sides of each mounting seat. Finally, the piston ends of the corresponding groups of spring push rods are bolted to an arc-shaped plate. This ensures that when the barrier arm descends and comes into contact with a vehicle, the arc-shaped plate contacts the vehicle body first, and the impact force is then transmitted to multiple spring push rods. The spring push rods absorb and disperse the impact energy through their internal elastic elements, transforming a rigid collision into a flexible buffer. This effectively avoids barrier arm deformation, damage to the drive mechanism, and damage to the vehicle's paint or structure caused by hard contact, achieving dual protection for both the barrier gate system and the vehicle. 2. To ensure the long-term stable operation of the buffer unit on the gate arm, preventing movement or loosening, and to facilitate initial installation and subsequent maintenance, this invention first welds several retaining rings onto the surface of the gate arm. These retaining rings are arranged in pairs at both ends of each main and auxiliary mounting base. This ensures that the position of the mounting base can be quickly determined during installation, and effectively limits the axial movement of the mounting base during use, preventing it from sliding freely on the gate arm and ensuring the accuracy of the buffer force point and the overall stability of the structure. Secondly, several fixing screws are used to connect the main and auxiliary mounting bases, forming an openable clamping structure. This allows the entire buffer unit to be easily fitted onto the designated section of the gate arm and firmly fixed by tightening the screws. The installation and disassembly processes are very simple, ensuring that all buffer components remain in their designed positions under dynamic working conditions. Attached Figure Description

[0009] The present invention will be further described in detail below with reference to the accompanying drawings.

[0010] As one embodiment of this utility model, reference is made to Figure 1-3 A vehicle entry / exit barrier gate buffer mechanism includes a gate arm 1. Three main mounting seats 3 are rotatably connected to the surface of the gate arm 1. A secondary mounting seat 4 is located on one side of each main mounting seat 3. Four sets of fixing screws 6 are threadedly connected to one side of each main mounting seat 3 and secondary mounting seat 4. Two sets of spring push rods 5 are bolted to each of the four sides of the surfaces of the main mounting seats 3 and secondary mounting seats 4. An arc-shaped plate 2 is bolted to the piston end of each set of spring push rods 5. The core of this invention is that when the gate arm 1 falls and accidentally contacts a vehicle, the arc-shaped plate 2 will first contact the vehicle body. The impact force is then absorbed and dispersed by the multiple spring push rods 5, transforming a rigid collision into a flexible buffer. This effectively avoids gate arm deformation, damage to the drive mechanism, and damage to the vehicle's paint or structure, achieving dual protection for both the barrier gate and the vehicle.

[0011] Furthermore, four sets of retaining rings 7 are welded to the surface of the gate arm 1. The two sets of retaining rings 7 are located at the two ends of the main mounting seat 3 and the auxiliary mounting seat 4, respectively, and the retaining rings 7 are used to limit the movement of the main mounting seat 3 and the auxiliary mounting seat 4.

[0012] Based on the above technical concept, it should be noted that when installing the buffer structure, the main mounting seat 3 and the auxiliary mounting seat 4 are fitted onto the surface of the gate arm 1, and the main mounting seat 3 and the auxiliary mounting seat 4 are exactly located between the corresponding two sets of retaining rings 7. Then, four sets of fixing screws 6 are passed through the auxiliary mounting seat 4 and connected to the inside of the main mounting seat 3. This completes the fixing of the main mounting seat 3 and the auxiliary mounting seat 4. It can be understood that the retaining rings 7 are set to provide precise axial positioning for the mounting seats, preventing them from sliding arbitrarily on the surface of the gate arm 1, and ensuring the accuracy of the buffer force point; while the screw connection method facilitates the installation and disassembly of the entire buffer unit, jointly ensuring the long-term stability and reliability of the structure. Furthermore, the main mounting base 3 and the auxiliary mounting base 4 can rotate on the surface of the gate arm 1. The retaining ring 7 can limit the sliding of the main mounting base 3 and the auxiliary mounting base 4 to prevent them from sliding freely on the surface of the gate arm 1. After the main mounting base 3 and the auxiliary mounting base 4 are installed, the spring push rod 5 and the arc plate 2 are installed and fixed. When the gate arm 1 presses against the top of the vehicle, the arc plate 2 will make direct contact with the top of the vehicle. The impact force generated will be offset by the spring push rod 5, thus completing the protection of the gate arm 1 and the vehicle.

[0013] In one embodiment of this utility model, reference is made to Figure 1-2 , Figure 4 Three sets of connecting brackets 8 are welded between the main mounting base 3 and the rotating shell 9. The rotating shell 9 is rotatably connected to one end of the gate arm 1. Two sets of connecting brackets 8 are welded between two adjacent sets of main mounting bases 3, and another set of connecting brackets 8 is welded between the main mounting base 3 and the rotating shell 9.

[0014] Furthermore, three sets of positioning holes 11 are provided on the surface of the rotating shell 9, and three sets of push rods 10 are welded to the surface of the rotating shell 9, and the push rods 10 are arranged in a rectangular shape. A fixed base 12 is fixedly sleeved at one end of the gate arm 1, and spring grooves 14 are provided on all four sides of the surface of the fixed base 12, and the spring grooves 14 are arranged in a cylindrical shape.

[0015] Furthermore, a telescopic spring 15 is connected to one side of the inner wall of the spring groove 14 via a spring fixing member, and a cone 13 is connected to the other end of the telescopic spring 15 via a spring fixing member, and the cone 13 is detachably connected to the positioning hole 11.

[0016] Based on the above technical concept, it should be noted that when the arc plate 2, which has been in contact with the vehicle multiple times, becomes worn, continued use may easily damage the vehicle. Therefore, this utility model proposes a rotational switching method to solve this problem. Specifically, the push rod 10 can be rotated, causing the rotating shell 9 to rotate on the surface of the fixed base 12. Since the surface of the cone 13 is inclined, when the cone 13 is squeezed by the positioning hole 11, it will retract into the spring groove 14, and the telescopic spring 15 will be compressed. Thus, the cone 13 will not obstruct the rotation of the rotating shell 9. When the rotating shell 9 rotates, it will cause the four sets of arc plates 2 to rotate synchronously, thereby switching the damaged arc plate 2. When the new arc plate 2 is switched to a position where it can contact the vehicle, the compressed telescopic spring 15 will reset and push the cone 13 outward. The pushed-out cone 13 will be positioned inside the positioning hole 11, thus completing the fixation of the rotating shell 9 and the arc plate 2. This design enables rapid replacement of worn parts. When a new arc-shaped plate 2 is switched to a position where it can contact the vehicle, the compressed telescopic spring 15 returns to its original position and pushes the cone 13 outward. The pushed cone 13 is then positioned inside the new positioning hole 11, completing the fixation. The solution proposed in this invention greatly extends the overall service life of the buffer mechanism and significantly reduces long-term maintenance costs and time.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
