Description
Technical Field
[0001] The utility model relates to the field related to new energy vehicles, and specifically to a shock-absorbing electric control box for a new energy vehicle. Background Art
[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures.
[0003] The electronic control box is an indispensable component in new energy vehicles, controlling, protecting, and managing electrical energy and serving as the core of the entire electronic control system. Because the powertrains of new energy vehicles differ from those of traditional vehicles, their control systems are more complex than those of ordinary vehicles, making the electronic control box particularly important. It carries out crucial responsibilities such as control, monitoring, and detection, directly impacting the vehicle's performance and safety. During driving, the vibration of the electronic control box can affect the stability and reliability of its internal electronic components. Therefore, developing an electronic control box with vibration reduction capabilities for new energy vehicles is particularly important.
[0004] For example, the Chinese authorized patent with announcement number CN 219734068 U (a shock-absorbing electric control box for new energy vehicles) includes a box body, a box chamber is provided in the box body, two vertical plates are fixedly installed in the box chamber, a plurality of mounting slots are provided on the vertical plates, and limit blocks are movably installed in the mounting slots through shock-absorbing components, and limit rods are movably installed on the plurality of limit blocks, and the plurality of limit rods are fixedly installed with the same mounting frame, and a plurality of groups of dampers and first shock-absorbing springs are used to effectively absorb shock and buffer the mounting frame. With the cooperation of a plurality of groups of second shock-absorbing springs and a plurality of third shock-absorbing springs, the mounting frame is fully buffered and shock-absorbed in the vertical and horizontal directions, thereby reducing the shaking of electronic components inside the electric control box when the car is driving, and reducing the occurrence of falling off at the connection of electronic components, thereby ensuring the normal operation of electronic components inside the electric control box and reducing the occurrence of failure of the electric control box when the new energy vehicle is driving.
[0005] Although the above-mentioned existing technology has the function of all-round buffering and shock absorption in the vertical and horizontal directions, the vertical and horizontal shock absorption relies on two sets of shock absorption systems, each of which is independent, resulting in a large number of shock absorption structures and points, and functional redundancy. Utility Model Content

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new energy vehicle shock-absorbing electric control box, comprising an electric control box body, wherein a shock-absorbing unit is fixedly provided at the lower end of the electric control box body;
[0008] The shock absorbing unit includes two first fixed vertical plates, a first transverse connecting rod is fixed between the two first fixed vertical plates, first sliding blocks are slidably connected to both sides of the outer side of the first transverse connecting rod, and the lower end of the first sliding block is integrally connected to the first fixed seat;

[0010] A rotation linkage rod is provided between the first fixing seat and the second fixing seat on each side, and both ends of the rotation linkage rod extend into the interior of the first fixing seat and the second fixing seat respectively and are rotationally connected to the first fixing seat and the second fixing seat respectively through an axis;

[0012] Preferably, a fixed end is fixed to one end of the damping shock-absorbing rod close to the rotating linkage rod, and a third fixed seat is fixed to one side of the rotating linkage rod close to the damping shock-absorbing rod. The outer end of the fixed end extends to the interior of the third fixed seat and is rotatably connected to the third fixed seat through an axis.
[0013] Preferably, a lower connecting bracket is fixed to the lower end of the electric control box body by bolts, and the lower connecting bracket includes a transverse connecting bracket and a longitudinal connecting bracket, and the transverse connecting bracket is integrally connected between the two longitudinal connecting brackets.
[0014] Preferably, a lower mounting tray is provided on the outside of the electric control box body, and the second fixed vertical plates are fixed to both sides of the lower end surface inside the lower mounting tray.

[0016] Preferably, a plurality of connecting spring rods are installed on the outer side of the longitudinal connecting frame at equal distances from front to back, and a vertical sliding plate is commonly fixed to the other ends of the plurality of connecting spring rods on each side.
[0017] Preferably, the inner periphery of the upper end of the lower mounting tray is integrally connected with an outer fixing frame, and vertical poles are fixed at the front and rear ends between the two longitudinal parts of the outer fixing frame and the lower end surface of the lower mounting tray, and the vertical sliding plate slides up and down along the vertical poles.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] 1. Significantly Improved Shock Absorption: The shock-absorbing unit utilizes a dual transverse connecting rod and sliding block design, coupled with a rotating linkage rod and damping shock-absorbing rods. This design allows for flexible response to up-and-down pitch and forward-and-backward forces, effectively dispersing and absorbing impact forces and ensuring the stability of the electronic control box under complex road conditions. Because the shock-absorbing structures on each side can slide in the same direction or simultaneously inward or outward, only two damping shock-absorbing rods are required for shock absorption. This solves the current problem of relying on two independent damping systems for vertical and lateral vibration absorption, resulting in a large number of damping structures, numerous locations, and functional redundancy.
[0020] 2. Enhanced structural strength: Through the design of the horizontal and vertical connecting frames of the lower connecting bracket, the combination of the connecting spring rod and the vertical sliding plate, and the limited sliding structure of the vertical sliding plate and the vertical pole, the overall connectivity and stability of the electric control box are enhanced, and the impact resistance is improved.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0029] See also Figure 1-6 , an embodiment provided by the utility model:
[0030] Connection between the electric control box body and the shock absorbing unit: The lower end of the electric control box body 1 is fixed with a lower connecting bracket 2 by bolts. The lower connecting bracket 2 consists of a transverse connecting frame 8 and a longitudinal connecting frame 9. The transverse connecting frame 8 is integrally connected between the two longitudinal connecting frames 9. The lower connecting bracket 2 enhances the supporting stability of the electric control box body 1. The shock absorbing unit 10 is arranged at the lower end of the electric control box body 1, and includes two first fixed vertical plates 11 and two second fixed vertical plates 13, which are respectively connected by a first transverse connecting rod 12 and a second transverse connecting rod 14. The first sliding block 17 and the second sliding block 19 are respectively slidably connected to the first transverse connecting rod 12 and the second transverse connecting rod 14, and are rotatably connected to the rotating linkage rod 21 through the first fixed seat 18 and the second fixed seat 20, thereby realizing flexible movement of the shock absorbing structure. This structural design enables the shock absorbing unit to flexibly respond to horizontal and vertical forces, and effectively disperse and absorb vibration energy. Damping and shock-absorbing rod configuration: The third fixed plate 16 is fixed to the center of the exterior of the second transverse connecting rod 14. A damping and shock-absorbing rod 22 is positioned between the third fixed plate 16 and the rotating linkage rod 21. One end of the damping and shock-absorbing rod 22 is fixedly connected to the third fixed plate 16, while the other end is pivotally connected to the rotating linkage rod 21 via a fixed end 23 and a third fixed seat 24. This allows for the regulation and transmission of the damping force. The damping and shock-absorbing rod provides a stable damping force, effectively suppressing the shaking of the electrical control box and improving the shock absorption effect. Lower mounting tray and connecting spring rod: The electrical control box body 1 is externally provided with a lower mounting tray 3. The second fixed plate 13 is fixed to both sides of the lower end surface of the lower mounting tray 3. A middle fixing block 15 is fixed to the center of the lower end surface of the lower mounting tray 3. The third fixed plate 16 is fixed to the upper end of the middle fixing block 15. Multiple connecting spring rods 7 are mounted equidistantly from front to back on the exterior of the longitudinal connecting frame 9. The other ends of the multiple connecting spring rods 7 on each side are commonly secured to a vertical sliding plate 6. This design allows the main body of the electrical control box to slide smoothly when it moves forward or backward, acting as a connection, primarily through the damping rods 22. The inner periphery of the upper end of the lower mounting tray 3 is integrally connected to the outer fixing frame 4. Vertical rods 5 are fixed to the front and rear ends between the two longitudinal portions of the outer fixing frame 4 and the lower end surface of the interior of the lower mounting tray 3. Vertical sliding plates 6 slide up and down along the vertical rods 5, ensuring that the main body of the electrical control box maintains a stable motion trajectory during vibration reduction, preventing damage to internal components caused by shaking.
[0031] Working principle: When bumping up and down, the distance between the electric control box body 1 and the lower mounting tray 3 changes passively due to the bumping, and the rotating linkage rod 21 rotates from an inclined state to a nearly horizontal state or the inclined angle is enlarged, and the second sliding block 19 slides outward along the second transverse connecting rod 14; the rotating linkage rod 21 rotates and drives the third fixed seat 24 to move, pulling the damping shock-absorbing rod 22 to extend or compress together, and the damping shock-absorbing rod 22 provides damping force to achieve a shock-absorbing effect.
[0032] When braking or accelerating, the electronic control box is subjected to the force in the forward direction or the reverse direction of the vehicle, and the two first sliding blocks 17 and the two second sliding blocks 19 move in the same direction, so that the shock-absorbing structure on the shock-absorbing unit 10 moves in the same direction at the same time, and one of the damping shock-absorbing rods 22 is extended and the other is compressed. The damping shock-absorbing rod 22 provides damping force to achieve a shock-absorbing effect.
[0033] When there are up and down bumps and front and rear forces, the above two shock absorption processes are superimposed, so that the movement trajectory of the shock absorption structure on each side of the shock absorption unit 10 is different, and the two damping shock absorption rods 22 have different damping effects, but also provide damping force for shock absorption.
[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
