Description

Technical Field

[0001] This invention specifically relates to a high-buffered anti-collision beam energy-absorbing box. Background Technology

[0002] Automotive crash beams are an important structural component of vehicles, designed to enhance vehicle safety in collisions. These beams are typically located at the front and rear of the vehicle, and their primary function is to absorb and disperse energy during a collision, thereby mitigating injury to vehicle occupants. A key component of the front and rear crash beam assemblies is the energy-absorbing box structure. The left and right sides of the crash beams are connected to the engine compartment longitudinal beams via energy-absorbing boxes, which buffer and release impact forces.

[0003] Existing crash beam energy-absorbing boxes mostly use wave-shaped curved structures for their energy-absorbing plates, which collapse upon impact to absorb energy. The structure is relatively simple and can only absorb energy once. Due to the curved design, the energy-absorbing plate will break at the curved point upon impact, and it cannot maintain the position of the energy-absorbing plate to continuously absorb the impact. Moreover, the energy absorbed in a single impact is relatively small, resulting in poor cushioning and impact protection. Therefore, we propose a high-buffering crash beam energy-absorbing box. Summary of the Invention

[0004] The purpose of this invention is to provide a high-buffered anti-collision beam energy-absorbing box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-buffered anti-collision beam energy-absorbing box, comprising:

[0006] The bottom plate of the box has energy-absorbing plates at both ends, and the energy-absorbing plates are recessed to one side to form a first collapse groove;

[0007] The collapse support is fixed to the bottom plate of the box, and the top of the collapse support is slidably connected to an elastic support that cooperates with the energy-absorbing plate to provide elastic support for one end of the energy-absorbing plate.

[0008] A rubber block is fitted onto the collapsible support, with one end of the rubber block contacting the elastic support to provide support for the elastic support.

[0009] Preferably, the elastic support includes a first elastic support portion, a connecting portion, and a second elastic support portion. The inner side of the second elastic support portion is provided with a connecting hole that cooperates with the collapsible support column. The first elastic support portion is fixed on the second elastic support portion, and the two ends of the first elastic support portion extend downward to form connecting portions, and the connecting portions are fixed to the first collapsible groove.

[0010] Preferably, both the first elastic support portion and the second elastic support portion are arc-shaped, and the arc length of the first elastic support portion is greater than the arc length of the second elastic support portion.

[0011] Preferably, the connecting part and the first elastic support part are integrally formed, and the curvature of the connecting part is the same as the curvature of the first collapse groove.

[0012] Preferably, a groove is formed at the lower end of the outer surface of the collapsible support.

[0013] Preferably, the upper end of the outer surface of the collapsible support is provided with a connecting ring groove that mates with the rubber block, and the outer diameter of the connecting ring groove is the same as the inner diameter of the rubber block.

[0014] Preferably, a buffer groove is provided on the outer surface of the rubber block along its circumference.

[0015] Preferably, a second shrinkage groove is provided on the lower surface of the box bottom plate, and the second shrinkage groove extends to both ends of the box bottom plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By incorporating crumple bars, rubber blocks, and elastic supports, this device avoids the situation where the energy-absorbing box only provides initial cushioning against impact through bent walls. After damage, the walls break at the bent points, resulting in poor energy absorption. This device provides elastic support at the first crumple groove, ensuring that the positions of the two walls remain unchanged during impact, thus improving the continuous energy absorption effect of the two walls. Furthermore, through multi-stage energy buffering, it can absorb more impact energy, effectively improving the cushioning and anti-collision effect. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-5 This invention provides a technical solution: a high-buffered anti-collision beam energy-absorbing box, comprising:

[0026] Box bottom plate 1, with energy-absorbing plates 2 at both ends, and the energy-absorbing plates 2 are recessed to one side to form a first collapse groove 3;

[0027] The collapsible support 4 is fixed to the bottom plate 1 of the box, so that it can better absorb the impact energy by collapsing itself when subjected to a large impact. The top of the collapsible support 4 is slidably connected to an elastic support 6 that cooperates with the energy-absorbing plate 2 to provide elastic support for one end of the energy-absorbing plate 2, so as to maintain the position of the energy-absorbing plate 2 and improve the continuous energy absorption effect of the energy-absorbing plate 2. Moreover, more impact energy can be absorbed through the step-by-step buffering of the elastic support 6.

[0028] Rubber block 5 is fitted onto collapsible support 4, and one end of rubber block 5 is in contact with elastic support 6 to support elastic support 6, so as to facilitate better cushioning effect.

[0029] In this embodiment, preferably, the elastic support 6 includes a first elastic support portion 61, a connecting portion 62, and a second elastic support portion 63. The inner side of the second elastic support portion 63 is provided with a connecting hole 65 that cooperates with the collapsible support column 4. The first elastic support portion 61 is fixed on the second elastic support portion 63, which facilitates the gradual absorption of impact energy through the first elastic support portion 61 and the second elastic support portion 63. The first elastic support portion 61 extends downward at both ends to form connecting portions 62, which facilitates the connection with the first collapsible groove 3 and helps to maintain the position of the energy-absorbing plate 2, thereby improving the impact energy absorption effect of the energy-absorbing plate 2.

[0030] In this embodiment, preferably, both the first elastic support portion 61 and the second elastic support portion 63 are arc-shaped, which facilitates the absorption of more energy through the longer first elastic support portion 61, and the arc length of the first elastic support portion 61 is greater than the arc length of the second elastic support portion 63.

[0031] In this embodiment, preferably, the connecting part 62 and the first elastic support part 61 are integrally formed, and the curvature of the connecting part 62 is the same as the curvature of the first collapse groove 3, so as to facilitate a larger contact area between the connecting part 62 and the first collapse groove 3, thereby improving the support effect and making the force more uniform.

[0032] In this embodiment, preferably, a groove 41 is provided at the lower end of the outer surface of the collapsible support 4, so that the collapsible support 4 can better collapse and absorb energy when it is impacted.

[0033] In this embodiment, preferably, a connecting ring groove 42 that mates with the rubber block 5 is provided on the upper end of the outer surface of the collapsible support 4, and the outer diameter of the connecting ring groove 42 is the same as the inner diameter of the rubber block 5, which facilitates the positioning and installation of the rubber block 5.

[0034] In this embodiment, preferably, a buffer groove 51 is provided on the outer surface of the rubber block 5 along its circumference, so as to facilitate a larger deformation space for the rubber block 5 and improve the energy absorption effect.

[0035] In this embodiment, preferably, a second collapse groove 7 is provided on the lower surface of the box bottom plate 1 to facilitate better energy absorption through collapse, and the second collapse groove 7 extends to both ends of the box bottom plate 1.

[0036] The working principle and usage process of this invention are as follows: In use, the bottom plate 1 is fixed to the car body with brackets and bolts, and the energy-absorbing plate 2 is fixed to the anti-collision beam. When the anti-collision beam is subjected to external impact, the energy-absorbing plate 2 and the first crumple zone 3 deform under force. At the same time, the first elastic support 61 is fixed to the energy-absorbing plate 2 through the connecting part 62, and the first elastic support 61 also deforms under force. Part of the deformation force of the first elastic support 61 is used to keep the two energy-absorbing plates 2 in a parallel state to ensure the energy absorption effect of the energy-absorbing plate 2, and the other part is used to buffer the impact force. At the same time, the second elastic support 63 and the rubber block 5 also deform along with the first elastic support 61. Through the gradual energy transfer, the impact force is weakened, and the buffering effect is gradually improved. When the impact force is large, the crumple column 4 is damaged through the groove 41 to absorb the impact energy and improve the safety of the car body.
