Description

Technical Field

[0001] This utility model belongs to the field of energy-absorbing box technology, specifically relating to a high-efficiency adaptive automotive energy-absorbing box component. Background Technology

[0002] Currently, common energy-absorbing boxes, as the core component of car bumper systems, are usually installed between the car's anti-collision beam and the body's longitudinal beams. They are mostly metal pleated structures that absorb energy through plastic deformation. However, in actual use, the energy absorption efficiency of the energy-absorbing box is relatively simple and difficult to adapt to different collision speeds. The overall energy absorption effect is not ideal, and the maintenance cost is high, which needs to be addressed. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a high-efficiency adaptive automotive energy-absorbing box assembly that combines a viscous damper with an energy-absorbing box to solve the above problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a high-efficiency adaptive automotive energy-absorbing box assembly, including an energy-absorbing box body detachably connected between the automotive anti-collision beam and the vehicle body longitudinal beam. The internal cavity of the energy-absorbing box body is divided into several chambers by several partitions fixed therein. Both the energy-absorbing box body and the partitions are metal pleated structures. A viscous damper can be detachably installed in each chamber.

[0005] Preferably, the front end of the energy-absorbing box body is open and fixedly fitted with a front mounting plate, and the rear end is closed and fixedly fitted with a rear mounting plate. The front mounting plate is fixedly connected to the vehicle anti-collision beam by several bolts, and the rear mounting plate is fixedly connected to the vehicle body longitudinal beam by several bolts.

[0006] Preferably, the energy-absorbing box body and the partition are both made of aluminum alloy or high-strength steel with a pleated structure.

[0007] Preferably, the front end of the viscous damper is flush with the front end of the energy-absorbing box body, and a threaded post is fixed on the rear end. The threaded post extends from the rear end of the energy-absorbing box body and is threaded with a nut.

[0008] The beneficial effects of this invention are as follows: By combining a viscous damper with an energy-absorbing box, multi-stage energy absorption is achieved through the shear energy dissipation of the damping fluid and the energy dissipation of the pore jet in the viscous damper. That is, the viscous damper has no effect or negligible effect at low speeds (15km / h), plays a certain role at 30km / h, and works together with the energy-absorbing box to improve the energy absorption capacity to a certain extent, reducing or preventing damage to the longitudinal beams of the vehicle body. At 50km / h and above, it can fully exert its energy dissipation function and work in synergy with the energy-absorbing box to significantly consume the impact collision energy of the vehicle while reducing the collision acceleration. The energy dissipation capacity can be matched according to the speed, which can adapt to different collision speeds and further enhance the energy absorption effect, resulting in better safety performance. In addition, the detachable design of the energy-absorbing box body and the viscous damper facilitates quick disassembly and replacement of the energy-absorbing box and the viscous damper, making it more flexible and convenient to use. Due to the effect of the viscous damper, the damage rate of the vehicle body longitudinal beam can be effectively reduced. At the same time, the viscous damper can be reused, thereby effectively reducing maintenance costs, increasing economic maintenance value, and making it more practical. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0015] like Figures 1 to 4 As shown, a high-efficiency adaptive automotive energy-absorbing box assembly includes an energy-absorbing box body 3 that is detachably connected between an automotive anti-collision beam 1 and a vehicle body longitudinal beam 2. The internal cavity of the energy-absorbing box body 3 is divided into several chambers 5 by several partitions 4 fixed therein. Both the energy-absorbing box body 3 and the partitions 4 are metal corrugated structures. Each chamber 5 is detachably equipped with a viscous damper 6.

[0016] By combining the viscous damper 6 with the energy-absorbing box, multi-stage energy absorption is achieved through the shear energy dissipation of the damping fluid and the energy dissipation of the pore jet in the viscous damper 6. That is, the viscous damper 6 has no effect or negligible effect at low speed (15km / h), plays a certain role at 30km / h, and works together with the energy-absorbing box to improve the energy absorption capacity to a certain extent, reducing the damage to the longitudinal beam 2 of the vehicle body or preventing damage. At 50km / h and above, it can give full play to its energy dissipation function and work together with the energy-absorbing box to significantly consume the impact collision energy of the vehicle while reducing the collision acceleration. The energy dissipation capacity can be matched according to the speed, which can adapt to different collision speeds and further enhance the energy absorption effect, resulting in better safety performance. Furthermore, the detachable design of the energy-absorbing box body 3 and the viscous damper 6 facilitates quick disassembly and replacement of both components, making them more flexible and convenient to use. Due to the function of the viscous damper 6, the damage rate of the vehicle's longitudinal beams 2 can be effectively reduced. Simultaneously, the viscous damper 6 is reusable, thereby effectively reducing maintenance costs, increasing economic maintenance value, and making it more practical. The viscous damper 6 can utilize existing technology, and its internal damping fluid can be silicone oil, magnetorheological fluid, hydraulic oil, water, or other liquids.

[0017] In this embodiment, the front end of the energy-absorbing box body 3 is open and fixedly fitted with a front mounting plate 7, and the rear end is closed and fixedly fitted with a rear mounting plate 8. The front mounting plate 7 is fixedly connected to the vehicle anti-collision beam 1 by several bolts 9, and the rear mounting plate 8 is fixedly connected to the vehicle body longitudinal beam 2 by several bolts 9, so as to facilitate the installation, fixation and quick removal of the energy-absorbing box body 3.

[0018] In this embodiment, both the energy-absorbing box body 3 and the partition 4 are made of aluminum alloy or high-strength steel with a pleated structure to ensure the energy absorption effect of the entire energy-absorbing box.

[0019] In this embodiment, the front end of the viscous damper 6 is flush with the front end of the energy-absorbing box body 3, and a threaded post 10 is fixedly provided on the rear end. The threaded post 10 extends from the rear end of the energy-absorbing box body 3 and is threadedly fitted with a nut 11, so as to facilitate the installation, fixation and quick removal of the viscous damper 6. When disassembling the viscous damper 6, simply remove the entire energy-absorbing box from between the vehicle anti-collision beam 1 and the vehicle body longitudinal beam 2, and then unscrew the nut 11 to remove the original viscous damper 6 from the energy-absorbing box body 3.

[0020] 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.
