Description
Technical Field
[0001] This utility model relates to the field of automotive anti-collision beam technology, specifically a connection structure for a front anti-collision beam of a new energy vehicle. Background Technology
[0002] A crash beam is a device used to absorb collision energy when a vehicle is involved in a collision. It consists of a main beam, an energy-absorbing box, and a mounting plate that connects to the car. Both the main beam and the energy-absorbing box can effectively absorb collision energy when a vehicle is involved in a low-speed collision, minimizing the damage to the longitudinal beams of the vehicle body and thus playing a protective role for the vehicle.
[0003] In existing technologies, some front bumper beams of new energy vehicles use simple welding or a few bolt connections, resulting in a relatively simple structure. This connection method is difficult to install due to the lack of a precise positioning structure, requiring a lot of time for alignment and fixing, leading to low installation efficiency. Moreover, the simple connection method makes the connection stability between the various components of the bumper beam poor. During long-term vehicle operation, the connection parts are prone to loosening due to factors such as vibration, which in turn affects the bumper beam's anti-collision effect.
[0004] In view of this, we have introduced a connection structure for the front anti-collision beam of new energy vehicles. Utility Model Content
[0005] The purpose of this utility model is to provide a connection structure for the front anti-collision beam of a new energy vehicle to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a connection structure for a front anti-collision beam of a new energy vehicle, comprising: a middle frame skeleton, an L-shaped positioning block, and an arc-shaped plate;
[0007] The inner part of the middle frame skeleton has a hollow groove, and the hollow groove and the middle frame skeleton are integrally formed. The hollow groove is provided with a positioning block, which can be fixed to the middle frame skeleton or integrally formed.
[0008] The L-shaped positioning block is disposed on one side of the positioning block, and a connecting plate is disposed on the other side of the L-shaped positioning block. The connecting plate and the L-shaped positioning block are fixedly disposed, or they can be integrally formed.
[0009] A plug is provided on one side of the arc-shaped plate. The plug is fixed to the arc-shaped plate and can also be integrally formed. The plug is inserted into the interior of the middle frame.
[0010] A connecting structure is provided on one side of the connecting plate. Through the cooperation of the assembly frame, assembly slot and assembly block of the connecting structure, the assembly block, assembly frame and connecting plate are installed on the side of the middle frame skeleton.
[0011] Preferably, the connecting structure includes a threaded hole A at the top of the assembly frame, the threaded hole A and the assembly frame being integrally formed, the assembly frame being connected to one side of the connecting plate, the assembly groove being formed inside the assembly frame, the assembly groove and the assembly frame being integrally formed, the assembly block being slidably fitted inside the assembly groove, the surface of the assembly block having a threaded hole B aligned with the threaded hole A, and the four corners of the surface of the assembly frame having threaded holes C, the threaded holes C and the assembly frame being integrally formed.
[0012] Preferably, threaded holes D are provided at the four corners of the surface of the connecting plate. The threaded holes D are aligned with the threaded holes C. The threaded holes C and D are connected by bolts A, and bolts A extend into the interior of the middle frame for fixing. During installation, bolts A are passed through threaded holes C and D, and the threaded part of bolts A extends into the interior of the middle frame. By tightening bolts A, the connecting plate, the assembly frame and the middle frame are tightly connected to achieve a stable fixing effect and ensure the reliability of the connection structure.
[0013] Preferably, the L-shaped positioning block has a screw hole A on its side, and screw hole A and the L-shaped positioning block are integrally formed. The positioning block has a screw hole B on its surface, and screw hole B and the positioning block are integrally formed. Screw hole A and screw hole B are aligned and connected by bolt B. This connection method achieves reliable fixation of the L-shaped positioning block and ensures that the L-shaped positioning block is stably positioned in the slot.
[0014] Preferably, the side of the assembly block is connected to a T-shaped slide rail, which is integrally formed with the assembly block, or it can be fixedly set. The inside of the assembly frame is provided with a T-shaped groove for sliding the T-shaped slide rail. The T-shaped slide rail on the side of the assembly block cooperates with the T-shaped groove inside the assembly frame, so that the assembly block can slide smoothly in the assembly groove and the position can be easily adjusted.
[0015] Preferably, the inner frame of the frame is provided with a sliding groove for sliding the insert block. The sliding groove and the frame are integrally formed. The sliding groove is provided to restrict the movement of the insert block and the arc plate.
[0016] Preferably, the inner frame of the frame has a cavity, which is integrally formed with the frame. An airbag is connected inside the cavity, and a silicone pad is connected to one side of the arc plate. The silicone pad is in contact with the airbag. Due to the contact between the silicone pad and the airbag, the airbag is compressed under impact. The cavity containing the airbag is located inside the frame, and the airbag will deform when compressed, using the compressibility of gas to further absorb and disperse the impact force.
[0017] Preferably, the threaded hole B and the threaded hole A are connected by bolt C. After the threaded hole A on the top of the assembly frame is aligned with the threaded hole B on the surface of the assembly block, they are connected by bolt C to fix the assembly block and the assembly frame.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] (1) By using insert blocks and sliding grooves, bolt B to connect positioning blocks and L-shaped positioning blocks, bolt A to connect assembly frames and connecting plates and fix them to the middle frame skeleton, the entire anti-collision beam connection structure is accurately positioned and easy to operate during installation, which improves installation efficiency. At the same time, this multi-component cooperative connection method enhances the connection stability between components and ensures that the anti-collision beam will not easily loosen during vehicle operation.
[0020] (2) The sliding fit of the T-shaped slide rail and T-shaped slide groove between the assembly block and the assembly frame makes it easy to fine-tune the position of the assembly block during installation, ensuring that the threaded hole A and the threaded hole B are accurately aligned, which facilitates the subsequent installation of bolt C. The fastening connection of multiple bolts (bolt A, bolt B, bolt C) further ensures the stability of the connection structure, enabling the anti-collision beam to better withstand the huge external force generated during the collision.
[0021] (3) The buffer structure composed of the arc plate, silicone pad and airbag plays an important role in the collision. The arc plate, as the direct force-bearing component, initially disperses the impact force; the elastic buffer of the silicone pad and the gas compression buffer of the airbag form a multi-level buffer mechanism, which can more effectively absorb the collision energy, reduce the damage to the key components of the vehicle and the people in the vehicle, and improve the safety performance of new energy vehicles.
[0022] (4) By placing the airbag inside the cavity of the mid-frame, it can absorb the impact force during a collision, thereby reducing the stress on the mid-frame and other front structures of the vehicle, helping to maintain the integrity of the vehicle structure and reducing the repair cost and difficulty of the vehicle after a collision.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a connection structure for a front anti-collision beam of a new energy vehicle, including: a middle frame 1, the middle frame 1 having a slot 2 inside, and a positioning block 4 being provided inside the slot 2;
[0030] L-shaped positioning block 6, the L-shaped positioning block 6 is disposed on one side of positioning block 4, and a connecting plate 7 is disposed on the other side of L-shaped positioning block 6;

Through the cooperation of the assembly frame 9, assembly groove 10 and assembly block 13 of the connecting structure, the assembly block 13, assembly frame 9 and connecting plate 7 are installed on the side of the middle frame skeleton 1.
[0033] The connecting structure includes a threaded hole A11 on the top of the assembly frame 9, which is integrally formed with the assembly frame 9. The assembly frame 9 is connected to one side of the connecting plate 7. The assembly groove 10 is formed inside the assembly frame 9, and is integrally formed with the assembly frame 9. The assembly block 13 slides inside the assembly groove 10. The surface of the assembly block 13 has a threaded hole B14, which is aligned with the threaded hole A11. Threaded holes C12 are formed at the four corners of the surface of the assembly frame 9, and are integrally formed with the assembly frame 9.
[0034] The connecting plate 7 has threaded holes D8 at its four corners. The threaded holes D8 are aligned with the threaded holes C12. The threaded holes C12 and D8 are connected by bolts A, which extend into the interior of the middle frame 1 for fixing. During installation, bolts A are passed through the threaded holes C12 and D8, with the threaded portion of bolts A extending into the interior of the middle frame 1. By tightening bolts A, the connecting plate 7, the assembly frame 9, and the middle frame 1 are tightly connected, achieving a stable fixing effect and ensuring the reliability of the connection structure.
[0035] The L-shaped positioning block 6 has a screw hole A17 on its side, and the screw hole A17 and the L-shaped positioning block 6 are integrally formed. The positioning block 4 has a screw hole B5 on its surface, and the screw hole B5 and the positioning block 4 are integrally formed.

This connection method ensures that the L-shaped positioning block 6 and the positioning block 4 are reliably fixed, and ensures that the L-shaped positioning block 6 is stably positioned in the slot 2.
[0036] The side of the assembly block 13 is connected to a T-shaped slide rail 15. The T-shaped slide rail 15 and the assembly block 13 are integrally formed or fixed. The interior of the assembly frame 9 is provided with a T-shaped groove 16 for sliding the T-shaped slide rail 15. The T-shaped slide rail 15 on the side of the assembly block 13 cooperates with the T-shaped groove 16 inside the assembly frame 9, so that the assembly block 13 can slide smoothly in the assembly groove 10 and the position can be easily adjusted.
[0037] The inner frame 1 has a sliding groove 18 for sliding the insert 19. The sliding groove 18 and the inner frame 1 are integrally formed. The sliding groove 18 is used to restrict the movement of the insert 19 and the arc plate 3.
[0038] The inner cavity 22 of the middle frame 1 is integrally formed with the middle frame 1. An airbag 21 is connected inside the cavity 22. A silicone pad 20 is connected to one side of the arc plate 3. The silicone pad 20 is in contact with the airbag 21. Due to the contact between the silicone pad 20 and the airbag 21, the airbag 21 is compressed under the impact force. The cavity 22 where the airbag 21 is located is located inside the middle frame 1. The airbag 21 will deform when compressed, and the compressibility of the gas will be used to further absorb and disperse the impact force.
[0039] The threaded hole B14 and the threaded hole A11 are connected by bolt C. After the threaded hole A11 on the top of the assembly frame 9 is aligned with the threaded hole B14 on the surface of the assembly block 13, they are connected by bolt C to fix the assembly block 13 to the assembly frame 9.
[0040] Specifically, during use, the insert 19 on one side of the arc plate 3 is inserted into the sliding groove 18 inside the middle frame 1. This insertion method provides the arc plate 3 with a preliminary positioning and installation foundation, so that the arc plate 3 can be stably connected to the middle frame 1. The sliding groove 18 guides the insert 19, which facilitates accurate alignment during installation.
[0041] The positioning block 4 is located in the slot 2 of the middle frame 1. The L-shaped positioning block 6 is set on one side of the positioning block 4. After the screw hole A17 on the side of the L-shaped positioning block 6 is aligned with the screw hole B5 on the surface of the positioning block 4, they are connected by bolt B. This connection method realizes the reliable fixation of the L-shaped positioning block 6 and the positioning block 4, ensuring that the L-shaped positioning block 6 is stable in the slot 2, and providing an accurate positioning reference for subsequent connected components.
[0042] The connecting plate 7 is installed on the side of the middle frame 1 via the L-shaped positioning block 6. The assembly frame 9 is connected to one side of the connecting plate 7. The assembly block 13 slides in the assembly groove 10 inside the assembly frame 9. The T-shaped slide rail 15 on the side of the assembly block 13 cooperates with the T-shaped slide groove 16 inside the assembly frame 9, so that the assembly block 13 can slide smoothly in the assembly groove 10, which is convenient for adjusting the position. After the threaded hole A11 on the top of the assembly frame 9 is aligned with the threaded hole B14 on the surface of the assembly block 13, it is connected by bolt C to fix the assembly block 13 to the assembly frame 9. At the same time, the threaded holes C12 at the four corners of the surface of the assembly frame 9 are aligned with the threaded holes D8 at the four corners of the surface of the connecting plate 7. Bolts A are used to pass through these aligned threaded holes and extend into the middle frame 1 for fixation, thereby firmly installing the connecting plate 7, the assembly frame 9 and the assembly block 13 on the side of the middle frame 1.
[0043] When a new energy vehicle experiences a frontal collision, the impact force first acts on the curved plate 3. The curved plate 3 then transfers the impact force to the silicone pad 20 in contact with it. The silicone pad 20 has a certain degree of elasticity and can initially buffer part of the impact force. Since the silicone pad 20 is in contact with the airbag 21, the airbag 21 is compressed under the impact force. The cavity 22 where the airbag 21 is located is set inside the mid-frame frame 1. The airbag 21 will deform when compressed, and the compressibility of the gas will be used to further absorb and disperse the impact force, reducing the damage to the front structure of the vehicle and the occupants. If the impact force is too large, the mid-frame frame 1 will be used to buffer the impact force for easy use.
[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
