Description

Technical Field

[0001] This invention relates to the field of automotive bumpers, specifically a high-impact automotive bumper. Background Technology

[0002] With the increasing prevalence of automobiles in people's daily lives, and in the current era of rapid development in the automotive industry with increasingly fierce competition among car manufacturers, both manufacturers and consumers have higher and higher requirements for the quality of car appearance. As the largest exterior component of a car, the front bumper's installation and matching with surrounding parts directly affects the quality of the car's appearance. Furthermore, as a front body panel, the front bumper assembly provides protection for front-side components and pedestrians in the event of a low-speed collision.

[0003] The truck front bumper, installed on the lower front side of the truck cab, is a safety device that absorbs and mitigates external impacts, protecting the front of the vehicle. It protects the vehicle and driver during a collision. Existing heavy-duty truck bumpers typically employ hydraulic or honeycomb energy-absorbing structures to ensure energy absorption. However, in a collision, these structures often have a large impact area, resulting in limited buffer travel and potentially severe vehicle damage. Furthermore, the energy-absorbing components are often located in the center, leaving the edges and corners vulnerable to damage to the front of the vehicle.

[0004] Therefore, the present invention provides a high-buffer travel car bumper, which is based on the existing heavy truck surround bumper. It can achieve the first layer of energy absorption buffer in front of the vehicle and on the side through the front energy absorption barrier and the side barrier, and achieve the second layer of energy absorption buffer through the energy absorption buffer plate. At the same time, the impact-resistant component provides energy absorption buffer for the first layer of energy absorption buffer and the second layer of energy absorption buffer, thereby reducing the impact force of instantaneous impact. Summary of the Invention

[0005] The purpose of this invention is to provide a high-impact automotive bumper to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-impact car bumper, comprising:

[0007] The bumper body is mounted on the front side of the truck's front end. The bumper body has a bumper frame, a front trim panel, and hinges. The front trim panel is installed on the front side of the bumper frame, and hinges are provided on both sides of the bumper frame.

[0008] The positive energy-absorbing barrier is distributed on the inner side of the front decorative panel. The positive energy-absorbing barrier includes multiple barriers, each of which has an energy-absorbing layer on its inner side. The two adjacent barriers are connected by an energy-absorbing folding plate.

[0009] Lateral baffles are distributed on both sides of the bumper frame. The ends of the lateral baffles near the bumper frame are movably connected to the bumper frame through multi-degree-of-freedom hinges.

[0010] Energy-absorbing buffer plates are located behind the front energy-absorbing barrier plates. There are two sets of energy-absorbing buffer plates, and their near ends are connected by a telescopic belt. The far ends of the two sets of energy-absorbing buffer plates are movably connected to the hinge pins on the side of the bumper frame.

[0011] The impact-resistant component is connected between the energy-absorbing buffer plate and the lateral barrier plate. The impact-resistant component includes an impact-resistant linkage and a multi-degree-of-freedom connector.

[0012] The lateral stabilization assembly is installed on the rear side of the lateral barrier plate. The lateral stabilization assembly includes a stabilizing seat, an upper support arm, a lower support arm, a reinforcing beam, a buffer damper, and a base frame. The stabilizing seat is fixed to the rear side of the lateral barrier plate, and the upper support arm and lower support arm are respectively hinged to the upper and lower sides of the stabilizing seat.

[0013] Preferably, the energy-absorbing baffle is composed of multiple baffles connected together. The energy-absorbing baffle can be freely bent and extended. An elastic strap is fixed to two adjacent baffles by bolts. The positive energy-absorbing baffle can absorb energy by bending through the energy-absorbing baffle after being subjected to force, and the energy is absorbed by the deformation of the elastic strap.

[0014] Preferably, the impact-resistant link includes impact-resistant hydraulic rods and movable nodes, wherein multiple impact-resistant hydraulic rods are provided, and two adjacent impact-resistant hydraulic rods are connected by movable nodes.

[0015] Preferably, the reinforcing beam is connected to the front and rear sides of the upper and lower support arms by pins, and the buffer damper is connected between the lower support arm and the reinforcing beam.

[0016] Preferably, the multi-degree-of-freedom connector is connected to the front and rear ends of the impact-resistant link and is respectively connected to the back side of the energy-absorbing buffer plate and the side of the lateral barrier plate.

[0017] Preferably, the energy-absorbing layer includes a substrate, a molybdenum foam energy-absorbing block, an energy-absorbing damper, and a plastic plate. The molybdenum foam energy-absorbing block is bonded to the front side of the substrate. The molybdenum foam energy-absorbing block has several grooves, and each groove is fitted with an energy-absorbing damper. The energy-absorbing damper is a hydraulic damper, and a plastic plate is provided at the front end of the hydraulic damper.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention can achieve a first layer of energy absorption buffer in front of and to the side of the vehicle through a forward energy absorption barrier and a side barrier, and a second layer of energy absorption buffer through an energy absorption buffer plate. At the same time, the impact-resistant component provides hydraulic energy absorption buffer for the first and second layers of energy absorption buffer. Due to the high buffer stroke, the instantaneous impact force can be greatly reduced.

[0020] 2. The positive energy-absorbing barrier plate of the present invention adopts the design of an energy-absorbing folding plate. The energy-absorbing folding plate can be bent and stretched freely. When the positive energy-absorbing barrier plate is subjected to force, the energy-absorbing folding plate bends to absorb energy, and the energy is buffered by the deformation of the elastic belt, thereby buffering the impact force.

[0021] 3. When the positive energy-absorbing barrier fails due to excessive impact force, the installed energy-absorbing buffer plate can block the positive energy-absorbing barrier plate and achieve buffer energy absorption through impact bending of the telescopic belt. At the same time, the impact-resistant component provides buffer support to prevent the energy-absorbing buffer plate from being damaged by excessive impact force.

[0022] 4. The lateral barrier provided by the present invention plays a role in blocking the side of the vehicle front. When the vehicle front is subjected to lateral impact force, the lateral barrier acts as the first layer of barrier. At the same time, the impact-resistant component and the lateral stabilization component can also provide buffer support to ensure the lateral buffer of the vehicle front.
