Problems solved by technology

[0004] In the existing leg energy-absorbing device, the first connecting piece and the second connecting piece are connected by a nylon bolt, and when a frontal high-speed collision occurs, the nylon bolt is cut off quickly, and the first connecting piece moves along the axis of the second connecting piece. There is no energy-absorbing mechanism capable of absorbing the forces of a high-speed collision

Embodiment 1

[0040] Such as Figure 1 ~ Figure 3 as shown, figure 1 Schematic diagram of the structure of the first energy-absorbing device provided in the embodiment of the present application; figure 2 A schematic diagram of the X-direction of the first energy-absorbing device provided in the embodiment of the present application; image 3 It is a schematic diagram of the Y-direction of the first energy-absorbing device provided in the embodiment of the present application.

[0041] An energy-absorbing device 1 includes a first support plate 11 and a second support plate 12, at least two energy-absorbing plates 13 are arranged between the first support plate 11 and the second support plate 12, and the two ends of the energy-absorbing plates 13 Connect with the first support plate 11 and the second support plate 12 respectively; set at least one guide bend on the energy-absorbing plate 13, when the first support plate 11 moves toward the second support plate 12 along the first directio...

Embodiment 2

[0054] Such as Figure 4 as shown, Figure 4 It is a schematic diagram of the X-direction of the second energy-absorbing device provided by the embodiment of the present application.

[0055] Furthermore, along the first direction Z, the length of the energy-absorbing plate 13 in the second direction Y increases sequentially.

[0056] Specifically, the projection of the energy-absorbing plate 13 on the projection plane is a right-angled trapezoid, and the projection plane is perpendicular to the first support plate 11 and parallel to the second direction Y.

[0057] As mentioned above, as the length of the energy-absorbing plate 13 in the second direction Y increases sequentially, the compression resistance also gradually increases. Shorter, the first guide bend 131 is easily deformed, thereby absorbing the energy generated by the impact to achieve active energy absorption; because the length of the third guide bend 133 in the second direction Y is longer, the resistance of ...

Embodiment 3

[0059] Such as Figure 5 as shown, Figure 5 It is a schematic diagram of the second viewing angle of the third energy-absorbing device provided in the embodiment of the present application.

[0060] Specifically, along the first direction Z, the angles of the guide bends increase sequentially.

[0061] As mentioned above, the angles at the guide bends increase sequentially along the first direction Z. Since the angle at the first guide bend 131 is relatively small, the first guide bend 131 is easily deformed to absorb the impact. The generated energy maximizes the effect of energy absorption; the angle at the third guide bend 133 is relatively large, and the compression resistance is relatively high, so that it can withstand a relatively large impact.

[0062] Based on the same technical concept, the present invention also provides a vehicle, for details, reference may be made to the following embodiments.

[0063] A vehicle comprises a plurality of energy-absorbing device...

Abstract

The invention relates to the technical field of vehicle safety, in particular to an energy absorption device and a vehicle. The energy absorption device comprises a first support plate and a second support plate, and at least two energy absorption plates are arranged between the first support plate and the second support plate; the two ends of each energy absorption plate are connected with the first support plate and the second support plate separately; the direction from the first support plate to the second support plate is defined as a first direction; each energy absorption plate is provided with at least one guide bending part; and when the first support plate is moved towards the second support plate in the first direction, the energy absorption plates can be bent at the guide bending parts. In case of collision accident of the vehicle, the energy absorption plates can be bent at the guide bending parts, and crumpled from one end of each guide bending part under the guide effects of the guide bending structures of the energy absorption plates in sequence one by one, so that energy generated due to collision is absorbed through crumple deformation; and active energy absorption is achieved, so that injury to legs of passengers is reduced greatly.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to an energy absorbing device and a vehicle. Background technique [0002] With the rapid development of the economy, automobiles have become the main means of transportation for people to travel. The increase in the use of automobiles has led to frequent collision accidents. Due to the limited space of the vehicle, when a car collides and deforms the front panel parts of the car, it is easy to cause great damage to the thighs, calves and feet of the occupants. In car frontal collision accidents, the incidence rate of leg injuries is only behind the head. Because lower limb injuries are not fatal, they are often ignored by people. [0003] In the existing leg energy-absorbing device, a first connecting piece and a second connecting piece are arranged between the first footrest and the second footrest, and a collapse energy-absorbing mechanism is arranged on the first connect...
