Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a modular interlocking bumper anti-collision beam assembly. Background Technology

[0002] In the field of automotive safety, the bumper anti-collision beam assembly is one of the core components of a vehicle's passive safety system, and its performance directly affects occupant protection and the extent of vehicle damage in a collision. Traditional bumper anti-collision beam structures typically employ a one-piece design, with the anti-collision beam fixed to the bumper shell via rigid connectors. This design relies on a single energy-absorbing structure, primarily utilizing the plastic deformation of the anti-collision beam itself and a small number of energy-absorbing boxes at the front end to absorb collision energy. This type of design suffers from the following technical drawbacks:

[0003] Traditional energy-absorbing boxes are mostly single-stage structures that absorb energy through the deformation of metal sheets during a collision. However, the deformation pattern is uncontrollable, especially in low-speed collisions, where the energy-absorbing box fails before it has fully deformed, causing the impact force to be directly transmitted to the vehicle's longitudinal beams and resulting in a dent in the middle of the vehicle body. In addition, the lateral openings of traditional energy-absorbing boxes are mostly symmetrical designs, resulting in excessively fast deformation rates and making it difficult to optimize energy absorption efficiency.

[0004] In existing bumper assemblies, the buffer material is usually made of a single material (such as foam or rubber) and filled between the anti-collision beam and the guard plate, lacking a multi-level buffer mechanism. In low-speed collisions, the buffer material is prone to failure due to insufficient compression, and cannot effectively disperse impact energy; in high-speed collisions, a single buffer layer is difficult to work synergistically with the energy absorption box, resulting in discontinuous energy absorption. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a modular interlocking bumper anti-collision beam assembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A modular, interlocking bumper anti-collision beam assembly is characterized by comprising an anti-collision beam and a bumper, wherein the anti-collision beam is embedded in the rear side of the bumper, the bumper includes a fixed bracket, a protective plate is fixedly mounted on the front side of the fixed bracket, connecting ear plates are symmetrically arranged on both sides of the fixed bracket, the fixed bracket is a bending bracket, a groove is provided between the upper part of the fixed bracket and the protective plate, the groove is filled with buffer rubber, and a hydraulic buffer is fixedly mounted between the connecting ear plates and the protective plate.

[0008] Both ends of the anti-collision beam are equipped with a first energy-absorbing box and a first mounting plate. It also includes at least one energy-absorbing component arranged between the two first energy-absorbing boxes. The energy-absorbing component includes a second energy-absorbing box, a second mounting plate installed at the rear end of the second energy-absorbing box, and an insert block fixedly installed at the front end of the second energy-absorbing box. The front end of the insert block is inserted into the front end of the anti-collision beam, and the front end of the second energy-absorbing box contacts and presses against the anti-collision beam.

[0009] Preferably, the anti-collision beam consists of two horizontal beams arranged one above the other, with a transition space between the two beams, and the front end of the insert block is inserted into the transition space.

[0010] Preferably, the second energy-absorbing box is equipped with a spring inside, and the two ends of the spring abut against the second mounting plate and the insert block, respectively.

[0011] Preferably, the second energy-absorbing box has side openings on its sides, and the corresponding side openings on two adjacent sides are alternately arranged.

[0012] Preferably, a pressure block is fixedly connected to the front end of the second energy-absorbing box, and the second energy-absorbing box contacts and presses against the anti-collision beam through the pressure block.

[0013] Preferably, both ends of the two crossbeams are fixed by welding with reinforcing plates.

[0014] Preferably, there are two energy-absorbing components, located on both sides of the middle of the anti-collision beam.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] Multi-stage energy absorption optimization and a combined energy-absorbing structure (first energy-absorbing box + independent energy-absorbing components) form a dual buffer mechanism. During a collision, the anti-collision beam compresses the second energy-absorbing box, and the elastic deformation of the internal springs significantly reduces the transmission of impact force, effectively reducing the deformation of the vehicle's central section. A buffer rubber groove is installed between the bending frame fixing bracket and the guard plate, forming a three-stage buffer system with the hydraulic damper, absorbing impact energy even at low speeds.

[0017] The second energy-absorbing box adopts an asymmetrical alternating design for its side openings, which slows down the deformation rate of the energy-absorbing box. Compared with the traditional symmetrical opening structure, it improves energy absorption efficiency and provides better collision protection performance.

[0018] Modular and replaceable design: the energy-absorbing components and crash beams can be quickly connected via plugs to form independent, detachable units. After an accident, only the damaged energy-absorbing components need to be replaced. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] like Figures 1 to 5 As shown

[0027] This embodiment provides a modular, interlocking bumper anti-collision beam assembly, including an anti-collision beam 1 and a bumper 2. The anti-collision beam 1 is embedded in the rear side of the bumper 2. The bumper 2 includes a fixed bracket 21, a protective plate 22 is fixedly mounted on the front side of the fixed bracket 21, and connecting ear plates 23 are symmetrically arranged on both sides of the fixed bracket 21. The fixed bracket 21 is a bent bracket, and a groove 24 is provided between the upper part of the fixed bracket 21 and the protective plate 22. The groove 24 is filled with buffer rubber 25, and a hydraulic buffer 26 is fixedly mounted between the connecting ear plates 23 and the protective plate 22. This utility model features an embedded anti-collision beam 1 and bumper 2, resulting in higher strength. The modular design facilitates installation and disassembly.

[0028] Both ends of the anti-collision beam 1 are equipped with a first energy-absorbing box 5 and a first mounting plate 3. It also includes at least one energy-absorbing component 4 arranged between the two first energy-absorbing boxes 5. The energy-absorbing component 4 includes a second energy-absorbing box 41, a second mounting plate 42 installed at the rear end of the second energy-absorbing box 41, and an insert block 43 fixedly installed at the front end of the second energy-absorbing box 41. The front end of the insert block 43 is inserted into the front end of the anti-collision beam 1, and the front end of the second energy-absorbing box 41 contacts and presses against the anti-collision beam 1.

[0029] The first energy-absorbing box 5 is welded and fixed to the anti-collision beam 1. The first mounting plate 3 is welded to the first energy-absorbing box 5. The anti-collision beam 1 is installed on the car by mounting the first mounting plate 3. On this basis, an energy-absorbing component 4 is set. The energy-absorbing component 4 and the anti-collision beam 1 are independent units that can be combined and separated. Specifically, this is achieved by inserting the plug 43 into the middle of the anti-collision beam 1. During installation, the energy-absorbing component 4 is first installed on the car using the second mounting plate 42, and then the anti-collision beam 1 is installed on the car. When installing the anti-collision beam 1, the plug 43 is inserted into the front end of the anti-collision beam 1. When the car suffers a frontal collision, the anti-collision beam 1 compresses the second energy-absorbing box 41, and the second energy-absorbing box 41 absorbs energy and provides protection, thereby effectively reducing the deformation of the middle of the car and protecting the occupants and car parts. The modular structure makes the components easy to replace.

[0030] The anti-collision beam 1 consists of two horizontal beams arranged one above the other, with a transition space 11 between them. The front end of the insert block 43 is inserted into the transition space 11. By setting two beams, the overall width of the anti-collision beam 1 can be increased, thereby allowing the second energy-absorbing box 41 to be larger and provide better protection. Further, the instruction manual 4 states that a spring 44 is installed inside the second energy-absorbing box 41, with both ends of the spring 44 pressing against the second mounting plate 42 and the insert block 43, respectively. The elastic deformation of the spring 44 provides a buffering effect to reduce impact force.

[0031] The second energy-absorbing box 41 has side openings 411 on each side, with corresponding side openings 411 alternating on adjacent sides. Traditionally, instead of alternating openings, each side has the same number and height of openings, resulting in rapid deformation and poor energy absorption during energy absorption. This design, however, causes uneven deformation on adjacent sides, resulting in a slower deformation rate and better protection. Furthermore, a pressure block 45 is fixedly connected to the front end of the second energy-absorbing box 41, allowing it to contact and press against the anti-collision beam 1. The pressure block 45 prevents direct contact between the second energy-absorbing box 41 and the anti-collision beam 1, facilitating installation.

[0032] Two energy-absorbing components 4 are provided, located on either side of the middle of the anti-collision beam 1, to improve the buffering and energy absorption effect. In this embodiment, both ends of the two beams are welded and fixed by reinforcing plates 12 to increase the bonding strength.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
