Description

Technical Field

[0001] This utility model relates to the technical field of automotive safety accessories, and in particular to a vehicle energy-absorbing box. Background Technology

[0002] Collision safety performance is one of the main aspects of vehicle body structural safety design. Its main purpose is to reduce the degree of injury to occupants caused by a collision. This requires the vehicle body structure to have the ability to absorb energy and resist deformation. That is, when a vehicle is involved in a collision, its collision energy must be absorbed by specific parts of the vehicle body structure to minimize the acceleration of the vehicle impact.

[0003] Currently, most vehicles utilize the chassis structure itself to absorb energy, with structures such as the front and rear bulkheads and doors directly absorbing collision energy. However, this method has poor energy absorption, and the energy generated during a collision can easily be transferred directly to the chassis, posing safety hazards to occupants and electrical components. While there are existing anti-collision devices for vehicles that are bolted to movable beams in the chassis to absorb collision energy, these movable beams are costly and heavy, increasing the overall weight of the vehicle. Utility Model Content

[0004] To address the above shortcomings, this utility model proposes a vehicle energy-absorbing box, in which an arc-shaped hole is provided on the first upright plate and a notch is provided on the second upright plate, thereby guiding the first and second upright plates to generate rotational deformation during collision, which is beneficial to better absorb collision energy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vehicle energy-absorbing box includes: a fixing plate for fixing to the frame of a bus; a cylindrical first upright plate is provided on the upper surface of the fixing plate; a collision plate is provided on the upper part of the first upright plate; multiple arc-shaped holes are distributed circumferentially on the outer peripheral wall of the first upright plate; the arc-shaped holes are spirally arranged from bottom to top along the outer peripheral wall of the first upright plate; a second upright plate is provided inside the first upright plate; the second upright plate is perpendicular to the fixing plate; multiple notches are provided vertically at intervals on the two opposite side walls of the second upright plate; the opening direction of the notches faces the inner wall of the second upright plate.

[0007] Furthermore, the second upright plate has a plurality of circular holes in the middle along the vertical direction, the notches being semi-circular holes, and the center of each circular hole being located on the line connecting the centers of two semi-circular holes on the same horizontal plane.

[0008] Furthermore, there are two second upright plates, which are arranged in a cross shape on the fixed plate, and the centers of the two circular holes located on the same horizontal plane intersect.

[0009] Furthermore, multiple arc-shaped holes located on the same horizontal plane form a group, and multiple groups of arc-shaped holes are provided. The multiple groups of arc-shaped holes are distributed at intervals along the vertical direction on the first vertical plate, and the multiple arc-shaped holes and the corresponding semi-circular holes are alternately arranged along the vertical direction.

[0010] Furthermore, the fixing plate has a first through hole, and the collision plate has a second through hole, with the midpoint of the first through hole and the midpoint of the second through hole being concentrically arranged.

[0011] Furthermore, the fixing plate is rectangular in shape, and mounting holes are provided at each of the four corners of the fixing plate. The mounting holes are used to connect to the frame of the bus by bolts.

[0012] Furthermore, the collision plate is circular, and the midpoint of the second through hole is concentric with the center of the collision plate.

[0013] Furthermore, the fixing plate, the first upright plate, and the second upright plate are an integral structure, and the collision plate is welded to the inner wall of the first upright plate.

[0014] Compared with existing technologies, this utility model has the following beneficial effects:

[0015] 1. The first vertical plate has multiple angled arc-shaped holes, which can cause the first vertical plate to undergo torsional deformation during collision and collapse, which is beneficial for absorbing collision energy;

[0016] 2. The second vertical plate can strengthen the overall structure of the energy-absorbing box, and through the multiple notches and circular holes, it can further guide the first vertical plate to collapse around its center, preventing the first vertical plate from deforming too much in the radial direction.

[0017] 3. The overall structure is simple, which helps to reduce weight and material costs, and improves the economy of vehicle operation and maintenance;

[0018] 4. The mounting plate is connected to the vehicle frame with bolts, which simplifies the installation of the energy-absorbing box and makes it easier to replace the energy-absorbing box after a collision. Attached Figure Description

[0029] See Figures 1 to 4A vehicle energy-absorbing box includes: a fixing plate 100 for fixing to the frame of a bus; a cylindrical first upright plate 110 is provided on the upper end surface of the fixing plate 100; a collision plate 120 is provided on the upper part of the first upright plate 110; a plurality of arc-shaped holes 111 are distributed circumferentially on the outer peripheral wall of the first upright plate 110; the arc-shaped holes 111 are spirally arranged from bottom to top along the outer peripheral wall of the first upright plate 110; a second upright plate 130 is provided inside the first upright plate 110; the second upright plate 130 is perpendicular to the fixing plate 100; a plurality of notches 131 are provided vertically at intervals on the two side walls of the second upright plate 130; the opening direction of the notches 131 faces the inner wall of the second upright plate 130.

[0030] The vehicle energy-absorbing box with the above structure is simple in design, which helps reduce weight and material costs, and improves the economy of vehicle operation and maintenance. When the collision plate 120 is impacted, the force generated by the impact is transmitted to the first upright plate 110 and the second upright plate 130, thereby driving plastic deformation through the first upright plate 110 and the second upright plate 130 to absorb the impact kinetic energy. Among them, the arc-shaped hole 111 provided in the first upright plate 110 can cut off the local force transmission path, forcing the force transmission to concentrate at the uncut position, thereby guiding the first upright plate 110 to rotate around its center. Finally, the first upright plate 110 continuously compresses and twists to consume the impact energy generated by the collision. In addition, the second upright plate 130 not only strengthens the overall structure of the energy-absorbing box, which helps to prevent the first upright plate 110 from deforming radially during the collision, but also, through the notch 131 provided in the side wall of the first upright plate 110, can further guide the first upright plate 110 to rotate around its center, which is conducive to better consuming the impact energy.

[0031] It is understandable that the fixed plate 100, the first upright plate 110, the second upright plate 130 and the collision plate 120 are all made of steel plates, which not only helps to reduce material costs, but also utilizes the plastic deformation of metal under the impact to generate crushing, thereby converting internal energy into deformation energy, which helps to better absorb a portion of the vehicle collision energy.

[0032] See Figures 1 to 4 Furthermore, the second vertical plate 130 has multiple circular holes 132 arranged vertically in the middle, and the notch 131 is a semi-circular hole. The center of each circular hole 132 is located on the line connecting the centers of two semi-circular holes on the same horizontal plane. Specifically, the second vertical plate 130 has multiple semi-circular holes and circular holes 132 arranged vertically, which can intermittently cut off the transmission of local forces along the vertical direction of the second vertical plate 130. This is beneficial for better guiding the second vertical plate 130 to drive the first vertical plate 110 to generate rotational deformation around its center, so as to better dissipate collision energy.

[0033] See Figures 1 to 4Furthermore, two second upright plates 130 are provided, arranged in a cross shape on the fixed plate 100, with the centers of the two circular holes 132 on the same horizontal plane intersecting. Specifically, the arrangement of the two second upright plates 130 not only facilitates further enhancement of the internal structural strength of the energy-absorbing box, but also helps to evenly transmit the force generated by the collision to the first upright plate 110.

[0034] See Figures 1 to 3 Furthermore, multiple arc-shaped holes 111 located on the same horizontal plane are grouped together, and multiple groups of arc-shaped holes 111 are provided. These multiple groups of arc-shaped holes 111 are distributed at intervals along the vertical direction on the first vertical plate 110. The multiple arc-shaped holes 111 and the corresponding semi-circular holes are alternately arranged along the vertical direction, which is beneficial to intermittently cutting off the transmission path of the collision force along the vertical direction of the first vertical plate 110, thereby driving the first vertical plate 110 to compress and spirally deform during the collision, which is beneficial to better consume the collision energy.

[0035] See Figures 1 to 3 Furthermore, the fixing plate 100 has a first through hole 101 and the collision plate 120 has a second through hole 121. The midpoint of the first through hole 101 and the midpoint of the second through hole 121 are concentrically set, thereby reducing the weight of the energy-absorbing box by opening holes, which is beneficial to improving the lightweight of the product.

[0036] See Figures 1 to 3 Furthermore, the fixing plate 100 is rectangular, and mounting holes 102 are provided at each of its four corners. The mounting holes 102 are used to connect to the bus frame via bolts. Specifically, the bolt connection method facilitates the quick fixing of the energy-absorbing box to the required anti-collision position on the frame, and allows for rapid replacement after the energy-absorbing box is damaged in a collision, thus improving the efficiency of energy-absorbing box installation and disassembly.

[0037] See Figures 1 to 3 Furthermore, the collision plate 120 is circular, and the midpoint of the second through hole 121 is concentric with the center of the collision plate 120, which facilitates the formation of a hollow cylinder by the collision between the first upright plate 110 and the collision plate 120, and helps the collision plate 120 to uniformly transfer the collision energy to the first upright plate 110.

[0038] Furthermore, the fixing plate 100, the first upright plate 110, and the second upright plate 130 are an integral structure, and the collision plate 120 is welded to the inner wall of the first upright plate 110. It is understood that during installation, the fixing plate 100, the first upright plate 110, and the second upright plate 130 are fixed together by welding, and then the collision plate 120 is welded to the end face of the first upright plate 110, ultimately forming an integral energy-absorbing box, which helps simplify the manufacturing difficulty of the energy-absorbing box.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
