Description

Technical Field

[0001] This utility model relates to the field of highway anti-collision technology, and more specifically, to a highway anti-collision pad energy absorption structure. Background Technology

[0002] Highway crash barriers are safety protection devices installed along highways, at intersections, bridges, and other locations. Their main function is to absorb impact energy during a vehicle collision, reducing damage to the vehicle and its occupants. They typically consist of end caps, energy-absorbing material, side guardrails, crossbars, and rear supports. When a vehicle impacts a crash barrier, the end caps deform, the energy-absorbing material absorbs the collision energy, and the rear supports resist the vehicle's impact force, preventing further forward propulsion and effectively protecting the safety of passengers and reducing the severity of the accident. Highway crash barriers play a crucial role in improving highway traffic safety and reducing accident fatalities.

[0003] A search revealed an existing patent (publication number: CN220521171U) that discloses a highway crash pad structure, belonging to the field of highway crash pads. This highway crash pad structure includes a contact head, a support plate, and an energy-absorbing frame. The energy-absorbing frame includes several energy-absorbing cylinders, and the support plate includes a base plate section and a vertical plate section. Several sliding rods are fixedly installed on the contact head located at the connection between the contact head and the energy-absorbing frame. By setting the energy-absorbing structure of the highway crash pad to the frame structure of the energy-absorbing frame, when a vehicle impacts the energy-absorbing frame, the frame absorbs energy and contracts, achieving a good energy absorption effect. It also eliminates the need for protective beams, avoiding the risk of protective beams directly intruding or inserting into the passenger compartment, thus improving safety. Furthermore, the sliding rods used to limit the direction of contact head advancement move forward with the contact head, preventing reverse intrusion or insertion into the passenger compartment and avoiding interference with safety.

[0004] The aforementioned device presents two problems during use. Firstly, the gravel filling it with tends to accumulate and compact after repeated impacts, weakening its impact-resistant effect. Secondly, in the event of a severe impact, the energy-absorbing frame alone is insufficient to achieve the desired protective effect. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a highway crash pad energy-absorbing structure to solve the problems that the filling of gravel is easy to become dense, which weakens the impact effect, and at the same time, it is difficult to achieve the ideal protective effect through the energy-absorbing frame.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a highway crash pad energy-absorbing structure, comprising: a mounting post; a supporting mounting device mounted on the mounting post, the supporting mounting device being used for installation; a buffer auxiliary device mounted on the supporting mounting device, the buffer auxiliary device being used for buffering; a buffer contact device mounted on the buffer auxiliary device, the buffer contact device being used for auxiliary buffering; and an energy-absorbing device mounted on one side of the buffer contact device, the energy-absorbing device being used for impact energy absorption.

[0007] Preferably, the support installation device includes: a first mounting plate fixedly installed on the top of the mounting column, the first mounting plate having an installation groove, a support plate fixedly installed on the first mounting plate, an extension plate fixedly installed on one side of the support plate, and a diagonal brace fixedly installed between the support plate and the extension plate.

[0008] Preferably, the buffer auxiliary device includes: a connecting column one fixedly installed inside the mounting groove, a buffer spring one movably sleeved on the outer surface of the connecting column one, a movable block movably installed on the outer surface of the connecting column one, and a connecting column two fixedly installed on the top of the movable block.

[0009] Preferably, there are two sets of connecting post one, buffer spring one, movable block and connecting post two, and the two sets of connecting post one, buffer spring one, movable block and connecting post two are symmetrically arranged on the top of the mounting plate one.

[0010] Preferably, the buffer contact device includes: a contact head fixedly installed on the top of the second connecting column, a buffer filling plate fixedly installed inside the contact head, a second buffer spring fixedly installed on one side of the buffer filling plate, a buffer rubber plate fixedly installed on one side of the second buffer spring, the buffer rubber plate being movably installed inside the contact head, and a second mounting plate fixedly installed on one side of the buffer rubber plate.

[0011] Preferably, the energy-absorbing device includes: a mounting ring fixedly installed on one side of the support plate, a sliding rod movably installed on the support plate, the other end of the sliding rod being fixedly connected to one side of the second mounting plate, an energy-absorbing frame fixedly installed between the support plate and the mounting ring, and the interior of the energy-absorbing frame being filled with cushioning foam.

[0012] Preferably, multiple sets of the energy-absorbing frame and the cushioning foam are provided, and the multiple sets of the energy-absorbing frame and the cushioning foam are equidistantly arranged on the inner side of the slide bar.

[0013] Preferably, four sets of mounting rings and slide rods are provided, and the four sets of mounting rings and slide rods are equidistantly arranged on one side of the support plate and the mounting ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a road crash barrier energy-absorbing structure. When a vehicle impacts the barrier, the first point of contact is the contact head in the buffer contact device. Upon impact, the contact head moves backward, compressing the internal buffer filling material and buffer spring two, providing initial cushioning. Simultaneously, the buffer rubber plate also participates in the cushioning, transferring the force to the mounting plate two. The mounting plate two, via a sliding rod, moves the energy-absorbing frame in the energy-absorbing device backward. During compression, the buffer filling foam inside the energy-absorbing frame absorbs a significant amount of impact energy, achieving secondary energy absorption. Simultaneously, the movable block in the buffer auxiliary device slides on the connecting column one, compressing the buffer spring one, further cushioning the vehicle's impact force, reducing damage to the vehicle and its occupants, effectively protecting the safety of passengers and reducing the severity of accidents.
