Description

Technical Field

[0001] This invention relates to the field of new energy vehicle bumper technology, specifically a reinforced front bumper for electric new energy vehicles with internal support. Background Technology

[0002] With the global energy transition and the deepening popularization of environmental protection concepts, electric new energy vehicles have become the mainstream direction of the automotive industry development due to their core advantages of zero emissions, low noise, and high efficiency, and their market penetration rate continues to rise. Compared with traditional fuel vehicles, electric new energy vehicles have significant differences in body structure. The power battery pack is usually located at the bottom of the vehicle, which fundamentally changes the load distribution and impact resistance requirements of the front of the vehicle, and puts forward higher requirements for the structural strength and adaptability of the front protective components of the vehicle. As a core protective component at the front of a car body, the front bumper not only plays a crucial role in absorbing impact energy and reducing damage to the main body during low-speed collisions, but also needs to consider pedestrian protection, aerodynamic optimization, and overall vehicle aesthetics. In the field of electric new energy vehicles, the front bumper also needs to coordinate with the layout of high-voltage components at the front of the vehicle to provide safety protection for precision components such as charging ports, radars, and sensors, preventing them from being damaged in collisions, bumps, or complex road conditions, and ensuring the stable operation of the vehicle's power system and intelligent driving functions. Existing electric new energy vehicle front bumpers rely solely on external structures for energy absorption and collision protection. This results in a significant reduction in their energy absorption and collision protection effectiveness after the external shape deforms. For example, the car bumper disclosed in publication number CN106904138A only uses a rigid structure composed of a first shell, a second shell, and a connecting rod to absorb energy and protect against collisions. Furthermore, it only relies on springs to enhance the energy absorption and collision protection effect after the rigid structure composed of the first shell, the second shell, and the connecting rod deforms. As a result, its energy absorption and collision protection effect is poor and cannot improve the safety of new energy vehicles. Therefore, a reinforced front bumper with internal support for electric new energy vehicles is needed to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide an internally supported reinforced front bumper for electric new energy vehicles, in order to solve the problem mentioned in the background art that the existing front bumpers for electric new energy vehicles have poor energy absorption and anti-collision effects and cannot improve the safety of new energy vehicles.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An internally supported reinforced front bumper for electric new energy vehicles includes a bumper body and energy-absorbing boxes welded to its rear side. The energy-absorbing boxes are evenly distributed on the rear side of the bumper body and are perpendicular to the bumper body. The bumper body has an internal counteracting support mechanism, which includes arc-shaped plates at both ends inside the bumper body. The bumper body also has a reverse-pressure reinforcing mechanism, which includes a mounting column that can be moved through the bumper body. The bumper body is an arc-shaped hollow structure with equal-angle distributions about its arc center. A support plate is provided in front of the energy-absorbing boxes and is fixedly connected to the mounting column. The mounting column and the bumper body are concentric arc structures. Each energy-absorbing box has a mounting block welded to its opposite end, and the mounting block has a pre-drilled mounting hole for mounting it to the new energy vehicle.

[0005] Preferably, the offsetting support mechanism further includes an energy-absorbing plate disposed inside the bar body, and the number of sets of energy-absorbing plates is the same as the number of mounting columns.

[0006] Preferably, each group contains two energy-absorbing panels, and the two energy-absorbing panels in each group are installed in opposite directions. The energy-absorbing panels are all arched structures, and the arched surfaces of the two energy-absorbing panels in the same group are arranged opposite each other.

[0007] Preferably, the energy-absorbing plate is an elastic steel plate with an arched shape facing the arc of the bar.

[0008] Preferably, a reinforcing plate is provided between the energy-absorbing plates in the same group, and the two ends of the reinforcing plate are integrally welded to the corresponding energy-absorbing plate. The reinforcing plate is movably penetrated by the corresponding mounting column, and a second spring is sleeved on the outside of each mounting column. The two ends of the second spring are respectively located between the inner arc surface of the bar body and the reinforcing plate.

[0009] Preferably, each set of energy-absorbing plates has two arched plates in its internal area, and the two arched plates are respectively set on one side of the reinforcing plate and on the outer arc surface inside the bar. The arched surfaces of the two arched plates are also arranged opposite each other, and the two arched plates are also elastic steel plates. The arched plates are movably penetrated by the corresponding mounting columns.

[0010] Preferably, the reverse pressure reinforcing mechanism further includes a pressure guide sleeve fitted on the outside of each energy-absorbing box, and a spring is provided between the pressure guide sleeve and the rear side of the bar body, the spring being fitted on the outside of the corresponding energy-absorbing box.

[0011] Preferably, the mounting block is fixedly connected to a support seat on the side facing the bar body, and each support seat is axially connected to a pressure guide arm. One end of the pressure guide arm is axially connected to the end of the corresponding mounting column, and the other end of the pressure guide arm contacts and supports the side of the corresponding pressure guide sleeve facing away from the bar body.

[0012] Preferably, the pressure guide arm is H-shaped, and the ratio of the distance from the rotation center of the pressure guide arm to its two ends is not less than three, and the distance from the rotation center of the pressure guide arm to the end of its connecting mounting column is relatively long.

[0013] Preferably, only the outermost energy-absorbing box is connected to one pressure-guiding arm, and the energy-absorbing boxes in the middle position are all connected to two pressure-guiding arms.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The internally supported reinforced front bumper for electric new energy vehicles has an offsetting support mechanism inside the bumper body to enhance the rigidity and strength of the bumper body, thereby improving the bumper body's anti-collision and energy absorption effect. In addition, a reverse-pressure reinforcing mechanism is also provided on the bumper body, which can increase the support capacity of the offsetting support mechanism and the impact resistance of the energy absorption box before the bumper body is impacted, greatly improving the safety of new energy vehicles. 1. Setting up arched energy-absorbing plates and arched plates, and having the outer arc surfaces of the energy-absorbing plates and arched plates in the same group face each other, can greatly improve the strength of the bar. In addition, by setting reinforcing plates between the energy-absorbing plates in the same group, the deformation of the bar can cause the energy-absorbing plates to deform, and the reinforcing plates must be torn. This method will greatly increase the strength of the bar, which will help to further improve the strength of the bar. 2. Before the bumper is impacted, the support plate is impacted first. After the support plate is impacted, the mounting column connected to it will move to the rear of the bumper. Then, through the rotation of the pressure guide arm, the pressure guide sleeve will squeeze the spring, resulting in the bumper being subjected to pressure in the opposite direction of the impact force. This method can greatly reduce the impact force on the energy absorption box, thereby helping to improve the energy absorption effect of the energy absorption box. Combined with the greatly strengthened bumper, it can greatly improve the safety of new energy vehicles. Attached Figure Description

[0017] 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.

[0018] Please see Figures 1-8 The present invention provides the following technical solution: Example 1: To address the problem that previous electric new energy vehicle front bumpers relied solely on their external shape for energy absorption and collision prevention, resulting in poor energy absorption and collision prevention performance, the following technical solution is provided: a reinforced front bumper for electric new energy vehicles with internal support, comprising a bumper body 1 and energy-absorbing boxes 5 welded to its rear side. The energy-absorbing boxes 5 are evenly distributed on the rear side of the bumper body 1 and are set perpendicular to the bumper body 1. The bumper body 1 has an internal offset support mechanism, which includes arc-shaped plates 12 set at both ends inside the bumper body 1. Each energy-absorbing box 5 has a mounting block 3 welded to its opposite end of the bumper body 1, and the mounting block 3 has pre-drilled mounting holes for mounting it onto the new energy vehicle.

[0019] The offsetting support mechanism also includes energy-absorbing plates 13 installed inside the lever body 1. The number of groups of energy-absorbing plates 13 is the same as the number of mounting columns 4. Each group has two energy-absorbing plates 13, and the two energy-absorbing plates 13 in each group are installed in opposite directions. The energy-absorbing plates 13 are all arched structures, and the arched surfaces of the two energy-absorbing plates 13 in the same group are arranged opposite each other. The energy-absorbing plates 13 are elastic steel plates, and their arches are set towards the arc line of the lever body 1. A reinforcing plate 10 is provided between the energy-absorbing plates 13 in the same group, and the two ends of the reinforcing plate 10 are integrally formed with the corresponding energy-absorbing plate 13. The reinforcing plate 10 is movably penetrated by the corresponding mounting column 4 through the welding process. Each mounting column 4 is fitted with a spring 11 on its outer side. The two ends of the spring 11 are respectively located between the inner arc surface inside the bar body 1 and the reinforcing plate 10. Two arched plates 14 are provided in the internal area of ​​each set of energy-absorbing plates 13. The two arched plates 14 are respectively located on one side of the reinforcing plate 10 and on the outer arc surface inside the bar body 1. The arched surfaces of the two arched plates 14 are also arranged opposite each other. The two arched plates 14 are also elastic steel plates. The arched plates 14 are movably penetrated by the corresponding mounting column 4.

[0020] according to Figures 1-3 as well as Figure 7 When in use, the bumper is installed on the new energy vehicle through the mounting holes on the mounting block 3; When a collision occurs at the front of a new energy vehicle, the impact energy is transferred to the lever 1. After receiving the impact energy, the lever 1 will deform. During the deformation of the lever 1, the outer arc surfaces of the two energy-absorbing plates 13 in different groups will be squeezed, thereby offsetting part of the impact force. When the impact force is large and the reinforcing plate 10 is torn, the outer arc surfaces of the two energy-absorbing plates 13 in different groups will undergo large deformation along with the bar body 1. During the above process, the energy-absorbing plate 13, the arched plate 14, and the reinforcing plate 10 can greatly enhance the strength of the bar body 1, ensuring that it can withstand greater impact forces, thereby helping to improve the safety of new energy vehicles.

[0021] Example 2: To address the problem that the lack of buffering between the energy-absorbing box 5 and the bumper body 1 during the use of previous electric new energy vehicles resulted in a large impact force on the energy-absorbing box 5, leading to poor energy absorption performance, the following technical solution is provided: Specifically, a reverse-pressure reinforcing mechanism is also provided on the bumper body 1, and the reverse-pressure reinforcing mechanism includes a mounting column 4 that moves through the bumper body 1. The bumper body 1 has an arc-shaped hollow structure, and the bumper body 1 is equidistant from its arc center. A support plate 2 is provided in front of the energy-absorbing box 5, and the support plate 2 is fixedly connected to the mounting column 4. The mounting column 4 and the bumper body 1 have a concentric arc structure.

[0022] The reverse pressure reinforcement mechanism also includes a pressure guide sleeve 8 fitted on the outside of each energy-absorbing box 5, and a spring 9 is provided between the pressure guide sleeve 8 and the rear side of the bar body 1. The spring 9 is fitted on the outside of the corresponding energy-absorbing box 5. The mounting block 3 is fixedly connected to the support seat 6 on the side facing the bar body 1, and each support seat 6 is axially connected to a pressure guide arm 7. One end of the pressure guide arm 7 is axially connected to the end of the corresponding mounting column 4, and the other end of the pressure guide arm 7 contacts and supports the side of the corresponding pressure guide sleeve 8 facing away from the bar body 1. The pressure guide arm 7 is H-shaped, and the ratio of the distance from the rotation center of the pressure guide arm 7 to its two ends is not less than three. The distance from the rotation center of the pressure guide arm 7 to the end of the mounting column 4 is relatively long. Only the outermost energy-absorbing box 5 is connected to one pressure guide arm 7, and the middle energy-absorbing boxes 5 are connected to two pressure guide arms 7.

[0023] according to Figures 3-6 When a collision occurs at the front of a new energy vehicle, the support plate 2 will be squeezed first, causing the support plate 2 and the mounting column 4 to gradually approach the bar body 1 until the support plate 2 is tightly attached to the bar body 1. During the movement of the mounting column 4, it will drive the pressure guide arm 7 to rotate. During the rotation of the pressure guide arm 7, it will drive the pressure guide sleeve 8 to move outside the corresponding energy absorption box 5, thereby squeezing the spring 9. During the above process, the bar body 1 will be subjected to pressure in the opposite direction of the impact force, which can delay the deformation time of the energy-absorbing plate 13 and help improve the energy absorption effect of the energy-absorbing plate 13. By delaying the energy absorption effect of the energy-absorbing plate 13, the anti-collision energy absorption effect of the bumper can be further improved, thereby further ensuring the safety of new energy vehicles.
