Description

Technical Field

[0001] This utility model relates to the field of highway ETC lane technology, specifically to a collision avoidance and buffer protection device for electromechanical equipment in highway ETC lanes. Background Technology

[0002] The ETC lane electromechanical equipment anti-collision buffer protection device is a safety protection facility installed around ETC lane electromechanical equipment, such as toll booths, antennas, and traffic lights. It is mainly used to reduce the risk of vehicles colliding with electromechanical equipment and reduce accident losses and casualties.

[0003] The ETC lane electromechanical equipment anti-collision buffer protection device on the highway absorbs the kinetic energy of the vehicle impact through the deformation of the device itself, reduces the impact force of the collision, and protects the electromechanical equipment body and internal components from serious damage.

[0004] In the initial design phase, the parameters and performance of the energy-absorbing module were determined based on the typical collision energy of a small car, which is generally the impact load generated at a low speed and with a small mass. However, when encountering a collision with a large truck in actual operation, the large truck itself has a large mass and strong inertia, and the collision will generate an energy impact far exceeding that of a small car. Due to the limited energy threshold designed to be adapted, the energy-absorbing module will quickly reach its limit in the face of the high energy input of the truck collision, and its energy absorption process such as material deformation and structural collapse will be unable to continuously and fully dissipate the impact energy. This makes it difficult for the energy-absorbing module to effectively buffer and unload the force, causing more of the impact force to be transmitted to the downstream electromechanical equipment, which greatly increases the risk of equipment damage.

[0005] Therefore, a collision avoidance and buffer protection device for electromechanical equipment in highway ETC lanes is proposed to address the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a collision avoidance and buffer protection device for electromechanical equipment in ETC lanes on highways, in order to solve the problem that when encountering a large truck collision in actual operation scenarios, the energy absorption module is limited by its energy threshold design and cannot continuously and fully dissipate the impact energy in the face of the high energy input of the truck collision. As a result, the energy absorption module is unable to effectively buffer and unload the force, and more of the impact force is transmitted to the downstream electromechanical equipment, which greatly increases the risk of equipment damage.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The highway ETC lane electromechanical equipment anti-collision buffer protection device includes an energy-absorbing module, an outer covering steel plate fixedly installed on the outside of the energy-absorbing module, a main support structure fixedly connected to the lower end of the energy-absorbing module, and an anti-collision structure fixedly connected to the lower end of the main support structure.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figures 1-6 This utility model provides a technical solution:

[0030] The ETC lane electromechanical equipment anti-collision buffer protection device includes an energy-absorbing module 1, an outer covering steel plate 2 fixedly installed on the outside of the energy-absorbing module 1, a main support structure 3 fixedly connected to the lower end of the energy-absorbing module 1, and an anti-collision structure 4 fixedly connected to the lower end of the main support structure 3; the main support structure 3 includes a support frame 31, a guide groove 32 is opened at the center of the upper end of the support frame 31, a trigger rod 33 is slidably connected to the outside of the guide groove 32, a warning post 34 is fixedly connected to the upper end of the support frame 31, a return spring 35 is fixedly connected to the outer side of the lower end of the warning post 34, and a limit block 36 is fixedly connected to the outer ring of the return spring 35; the anti-collision structure 4 includes an anti-corrosion chamber 41, a sliding groove 42 is opened inside the anti-corrosion chamber 41, a compression spring 43 is fixedly connected to the bottom of the inner side of the sliding groove 42, a secondary anti-collision device 44 is fixedly connected to the upper end of the compression spring 43, the secondary anti-collision device 44 includes an anti-collision rod 441, a buffer post 442 is rotatably connected to the outside of the anti-collision rod 441, and an energy-absorbing hole 443 is opened inside the buffer post 442.

[0031] As a further implementation of the above technical solution: multiple energy-absorbing holes 443 are provided, and the shape of the energy-absorbing holes 443 is elliptical. The energy-absorbing holes 443 are distributed in a circular array on the inner side of the buffer column 442. When the buffer column 442 rotates or is subjected to force, energy is absorbed through the deformation of the hole wall, thereby improving the energy absorption efficiency of the buffer column 442. Under the premise of ensuring the structural strength of the buffer column 442, the opening is used to achieve weight reduction, avoid the device being too heavy and increasing the installation and maintenance costs, while maintaining the protective performance.

[0032] As a further implementation of the above technical solution: the reset spring 35 is set on the outer side of the lower end of the warning post 34 and the inner side of the limiting block 36. The limiting block 36 is set on the upper end of the secondary anti-collision device 44. One end of the limiting block 36 is rotatably connected to the outer side of the warning post 34. The anti-collision rod 441 connecting the warning post 34 and the secondary anti-collision device 44 realizes the force transmission connection between the main support structure 3 and the anti-collision structure 4.

[0033] As a further implementation of the above technical solution: the anti-corrosion chamber 41 is set underground, the sliding groove 42 is a vertically opened groove, the number of sliding grooves 42 is the same as the number of secondary anti-collision devices 44, the inner dimensions of the sliding groove 42 are adapted to the lower end dimensions of the secondary anti-collision device 44, the upper end of the secondary anti-collision device 44 and the upper end of the support frame 31 are located on the same horizontal plane, providing a vertical sliding track for the anti-collision rod 441 of the secondary anti-collision device 44, ensuring the stability of the displacement direction of the anti-collision rod 441, and allowing the compression spring 43 to accurately absorb energy.

[0034] As a further implementation of the above technical solution: the guide groove 32 is an elongated groove, the length of the guide groove 32 extends along the length direction of the support frame 31, the width of the guide groove 32 is adapted to the width of the trigger rod 33, and the length of the guide groove 32 is 1.2 times the length of the trigger rod 33, which limits the sliding trajectory of the trigger rod 33, ensures that the trigger rod 33 is displaced in a preset direction when impacted, avoids force transmission disorder caused by sliding deviation, and improves the accuracy of trigger response;

[0035] As a further implementation of the above technical solution: the warning post 34 is a cylindrical structure, and the warning posts 34 are evenly distributed along the upper end of the support frame 31. There are multiple warning posts 34. The reset spring 35 is sleeved on the lower outer side of the warning post 34. The number of reset springs 35 corresponds one-to-one with the number of warning posts 34, providing an installation reference for the reset springs 35, and enabling energy absorption by means of spring deformation.

[0036] As a further implementation of the above technical solution: the compression spring 43 is located between the bottom of the inner side of the sliding groove 42 and the lower end of the secondary anti-collision device 44. The anti-collision rod 441 is slidably connected to the inner side of the sliding groove 42. The upper end of the anti-collision rod 441 passes through the support frame 31 and is in close contact with the lower end of the limiting block 36. The number of anti-collision rods 441 and limiting blocks 36 corresponds one-to-one. During the upward sliding process of the anti-collision rod 441, it absorbs a large amount of energy through large compression deformation, serving as the secondary energy absorption core of the device to cope with strong impact forces.

[0037] Workflow: The vehicle first contacts the outer steel plate 2 covering the outer side of the energy-absorbing module 1. The outer steel plate 2 acts as an initial buffer and disperses the impact force, transferring the impact force to the energy-absorbing module 1. After being subjected to force, the energy-absorbing module 1 transmits the force to the main support structure 3 fixedly connected at the lower end. At the same time, if the impact force of the large vehicle causes the trigger rod 33 to be subjected to force, and the energy-absorbing module 1 is unable to withstand the impact force of the large vehicle and is damaged, the large vehicle will hit the trigger rod 33. The trigger rod 33 will slide along the elongated guide groove 32 opened at the center of the upper end of the support frame 31 in the main support structure 3, triggering the initial response. Under the action of the impact force, the trigger rod 33 will move towards the limiting block 36, while pressing one end of the inclined surface of the limiting block 36. The rotation of the limiting block 36 will drive... When the return spring 35 is compressed, one end of the limit block 36 rotates relative to the outside of the warning post 34, absorbing some energy through spring deformation. At the same time, the limit block 36 will move from the upper end of the anti-collision bar 441 to the surface of the support frame 31. At this time, the anti-collision bar 441, which is compressed at the bottom of the inner side of the sliding groove 42, will quickly bounce out according to the elastic force of the compression spring 43, and the bottom will still be located inside the sliding groove 42. The buffer post 442 rotates synchronously during the impact force of the large vehicle and the sliding process of the anti-collision bar 441. Due to the rotation and force of the buffer post 442, the impact energy is further dispersed and absorbed through structural deformation. The energy-absorbing holes 443 complete the absorption and dissipation of impact energy through material deformation, gradually reducing the impact force and preventing damage to the electromechanical equipment.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
