Abstract
Description
Technical Field
[0001] This utility model relates to the field of protection frame technology, and in particular to a controller redundancy protection frame for electric vehicle anti-collision buffer. Background Technology
[0002] The purpose of an electric vehicle redundancy controller is to provide backup control for critical systems, ensuring the safety and functionality of the vehicle in the event of a failure. During installation, the controller is typically installed inside a protective frame first, and then the protective frame is fixed to the vehicle.
[0003] Existing protective frames are typically metal frames, housing the controller for protection. However, these frames are prone to deformation and damage upon impact, which can lead to damage to the internal controller, resulting in poor impact protection. Furthermore, the protective frame cannot buffer the controller during impact, causing the entire impact force to be transferred to the controller, leading to damage and poor performance. Therefore, we propose a redundant protective frame for the controller's impact buffer in electric vehicles. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a redundant protection framework for the controller of an electric vehicle anti-collision buffer.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a redundant protection frame for the controller of an electric vehicle anti-collision buffer is designed, including a shell, a protective frame inside the shell, a mounting plate inside the protective frame, and a controller body mounted on the top of the mounting plate;
[0006] There is a gap between the outer edge of the protective frame and the inner edge of the outer shell, and a first support plate is installed at the corner of the protective frame, with the other end of the first support plate fixed at the corner of the outer shell.
[0007] The two adjacent first support plates, the protective frame, and the side of the outer shell form a receiving cavity. A pair of second support plates are symmetrically installed inside each receiving cavity. One end of each pair of second support plates is fixed to the inner wall of the outer shell, and the other end of each pair of second support plates is fixed to the side of the protective frame.
[0008] Two guide rods are symmetrically installed inside the protective frame. Each guide rod has a connecting block symmetrically slidably connected to its side. A second U-shaped block is fixedly installed on the top of each connecting block. A connecting rod is rotatably connected inside the second U-shaped block. The other end of each connecting rod is rotatably connected to the first U-shaped block, and the first U-shaped block is fixed to the bottom of the mounting plate.
[0009] Each guide rod is fitted with a buffer spring on its side. One end of each buffer spring rests against the side of the protective frame, and the other end of each buffer spring rests against the side of the corresponding connecting block.
[0010] Preferably, each pair of second support plates is inclined, and the end of each pair of second support plates near the protective frame is fixed to both sides of the protective frame.
[0011] Preferably, energy-absorbing boxes are installed at both ends of the outer shell, and creases are provided on the sides of the energy-absorbing boxes.
[0012] Preferably, a connecting plate is connected between two connecting blocks on the same side, and a damper is installed on one side of each connecting plate, with the other end of the damper fixed to the side of the protective frame.
[0013] Preferably, there is a gap between the edge of the mounting plate and the inner wall of the protective frame.
[0014] Preferably, the top of the housing is provided with a top cover that covers the opening at the top of the housing, and the edge of the top cover is fastened to the edge of the top of the housing by bolts.
[0015] Preferably, a cushioning pad is installed at the bottom of the top cover. The cushioning pad is made of cushioning rubber material, and when the top cover covers the top of the housing, the bottom of the cushioning pad is in contact with the top of the controller body.

[0017] 1. The energy-absorbing box can absorb and eliminate the impact force on the shell. The first and second support plates can support the shell and the protective frame to prevent the shell from being severely deformed or damaged over a large area due to collision, thus improving the anti-collision effect.
[0018] 2. Through the cooperation of the connecting rod with the first U-shaped block and the second U-shaped block, the horizontal or vertical impact on the controller body can cause the connecting block to slide along the guide rod, thereby controlling the extension and contraction of the buffer spring, buffering and eliminating the impact force, avoiding damage to the controller body, and improving the buffering effect.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Reference Figures 1-5 A redundant protection frame for a controller of an electric vehicle anti-collision buffer includes a housing 1, a protective frame 9 inside the housing 1, a mounting plate 8 inside the protective frame 9, a controller body 7 mounted on the top of the mounting plate 8, and the controller body 7 connected to the internal components of the electric vehicle through wires. The controller body 7 can provide backup control for the key systems of the electric vehicle, so that the safety and function of the vehicle can be maintained when a malfunction occurs.
[0027] like Figure 1 and Figure 5 As shown, there is a gap between the outer side of the protective frame 9 and the inner side of the outer shell 1, and a first support plate 2 is installed at the corner of the protective frame 9. The other end of the first support plate 2 is fixed at the corner of the outer shell 1. The first support plate 2 can support the protective frame 9 and the outer shell 1, increase the structural strength of the outer shell 1 and the protective frame 9, and improve the anti-collision effect.
[0028] like Figure 1 and Figure 5 As shown, two adjacent first support plates 2, the protective frame 9, and the side of the outer shell 1 form a receiving cavity 11. A pair of second support plates 5 are symmetrically installed inside each receiving cavity 11. One end of each pair of second support plates 5 is fixed to the inner wall of the outer shell 1, and the other end of each pair of second support plates 5 is fixed to the side of the protective frame 9. In actual use, the second support plates 5 can support the outer shell 1 and the protective frame 9, increase the structural strength of the outer shell 1 and the protective frame 9, and improve the anti-collision effect.
[0029] It should be noted that, as Figure 1As shown, each pair of second support plates 5 is inclined, and the end of each pair of second support plates 5 closest to the protective frame 9 is fixed to both sides of the protective frame 9. When a collision occurs, the second support plates 5 will deform or bend to both sides under external pressure, such as... Figure 5 As indicated by the middle arrow, it will not cause damage to the controller body 7, further improving the anti-collision effect.
[0030] like Figure 1 and Figure 4 As shown, energy-absorbing boxes 4 are installed at both ends of the outer shell 1. The sides of the energy-absorbing boxes 4 are provided with creases 3. Under the action of the creases 3, the outer surface of the energy-absorbing boxes 4 can be corrugated. When the energy-absorbing boxes 4 are hit by an external object, the energy-absorbing boxes 4 will bend and deform along the creases 3 to absorb the impact force generated by the collision and improve the anti-collision effect.
[0031] like Figure 2 and Figure 3 As shown, two guide rods 15 are symmetrically installed inside the protective frame 9. Each guide rod 15 has a connecting block 16 symmetrically slidably connected to its side. A second U-shaped block 14 is fixedly installed on the top of each connecting block 16. A connecting rod 13 is rotatably connected inside the second U-shaped block 14. The other end of each connecting rod 13 is rotatably connected to a first U-shaped block 10, which is fixed to the bottom of the mounting plate 8. A buffer spring 12 is fitted onto the side of each guide rod 15. One end of each buffer spring 12 abuts against the side of the protective frame 9, and the other end abuts against the side of the corresponding connecting block 16. When the outer casing 1 is impacted by an external object, the controller body 7 inside the outer casing 1 will move horizontally due to inertia. This will cause the connecting block 16 to move via the connecting rod 13, which in turn will push the buffer spring 12 to extend and retract. The deformation generated during the extension and retraction of the buffer spring 12 will buffer and eliminate the impact force, thus providing buffer protection for the controller body 7 and improving its performance.
[0032] It should be noted that when the vehicle encounters bumpy road sections during operation, the controller body 7 will sway up and down due to inertia. Simultaneously, the controller body 7, through the mounting plate 8, will cause one end of the connecting rod 13 to move up and down. This, in turn, under the action of the first U-shaped block 10 and the second U-shaped block 14, causes the connecting rod 13 to slide along the guide rod 15, thereby controlling the extension and retraction of the buffer spring 12 to provide cushioning protection for the controller body 7.
[0033] like Figure 3 As shown, a connecting plate 17 is connected between two connecting blocks 16 on the same side. A damper 18 is installed on one side of each connecting plate 17. The other end of the damper 18 is fixed to the side of the protective frame 9. The vibration of the buffer spring 12 can be controlled by the damper 18, so that the extension and contraction of the buffer spring 12 remains stable.
[0034] It should be noted that, as Figure 1 and Figure 2 As shown, the top of the outer casing 1 is provided with a top cover 6, which covers the top opening of the outer casing 1. The edge of the top cover 6 is fastened to the top edge of the outer casing 1 by bolts. A buffer pad 19 is installed at the bottom of the top cover 6. The buffer pad 19 is made of buffer rubber material. When the top cover 6 covers the top of the outer casing 1, the bottom of the buffer pad 19 contacts and connects with the top of the controller body 7. The top cover 6 can cover the inside of the outer casing 1, so that the controller body 7 is in a sealed space, thus protecting the controller body 7. When the controller body 7 moves, it will be buffered and protected by the buffer pad 19, thereby improving the protection effect.
[0035] Specifically, when this utility model is subjected to a collision, the energy-absorbing box 4 is first impacted by the external object. The energy-absorbing box 4 will deform along the crease 3. During the deformation process, it will absorb the impact force. The remaining impact force is transmitted to the outer shell 1. The outer shell 1 and the protective frame 9 are supported by the first support plate 2 and the second support plate 5, so that the outer shell 1 and the protective frame 9 will not undergo large deformation or damage. At the same time, under the action of the impact force on the outer shell 1, the mounting plate 8 and the controller body 7 will swing horizontally under the action of inertia. During the swing, the mounting plate 8 will drive the connecting block 16 to move under the action of the connecting rod 13. When the connecting block 16 moves, it will drive the buffer spring 12 to extend and retract. The deformation generated by the buffer spring 12 can eliminate the impact force, thereby buffering and protecting the controller body 7 and improving the use effect.
[0036] Furthermore, such as Figure 1 and Figure 5 As shown, there is a gap between the edge of the mounting plate 8 and the inner wall of the protective frame 9, so that the mounting plate 8 will not collide with the edge of the protective frame 9 when it moves.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
