Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harnesses, specifically to a short-distance stepped high-voltage bracket. Background Technology

[0002] The high-voltage systems of new energy vehicles place special demands on wiring harness fixation: they must ensure absolute safety under high-voltage conditions, preventing short circuits or fires caused by loose or worn wiring, while also effectively resisting the continuous vibrations and impacts that are unavoidable during vehicle operation. Traditional single-material fixation solutions struggle to balance structural strength and cushioning performance. This led to this innovative design: using a simple, rigid metal bracket as the fixing base, its precisely designed clamping structure combined with the synergistic effect of elastic rubber components. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model provides a short-distance stepped high-voltage support to solve at least one of the above-mentioned technical problems.

[0004] The technical solution of this utility model is: a short-distance stepped high-voltage support, comprising a support body, characterized in that the support body is a stepped iron support, the iron support includes an upper support, a connecting plate and a lower support, the upper support is connected to the upper end of the connecting plate, and the lower support is connected to the lower end of the connecting plate;

[0005] The connection between the upper support and the connecting plate is arc-shaped, and the connection between the upper support and the connecting plate is provided with a first reinforcing rib. The connection between the lower support and the connecting plate is arc-shaped, and the connection between the lower support and the connecting plate is provided with two second reinforcing ribs.

[0006] The top of the upper support is provided with an extension plate that bends upward, the end of the lower support bends downward, and a rectangular slot is provided in the center of the end of the lower support.

[0007] This invention provides reliable structural support and installation positioning through an iron bracket, while rubber components flexibly wrap and clamp the high-voltage cables, absorbing vibration energy. This combination of rigid metal support and flexible rubber protection aims to effectively address the challenges of fixing and protecting high-voltage cable harnesses under complex operating conditions with a simple and efficient structure, thereby improving the overall reliability of the system. The bending structure enhances torsional stiffness. The elastic deformation of the rubber components can absorb more than 80% of high-frequency vibration energy, preventing wear on the cable insulation layer. The overall solution meets the IP67 protection rating while reducing weight by 40% and increasing installation efficiency by 50% compared to traditional clamps. Its standardized interface design is compatible with mainstream vehicle platforms, significantly reducing the failure rate of high-voltage systems.

[0008] Further preferably, a circular bolt hole is provided in the center of the upper support, and the mounting position of the bolt hole is on the same straight line as the mounting position of the extension plate.

[0009] This facilitates subsequent modular assembly.

[0010] Further preferably, the diameter of the bolt hole is the same as the width of the extension plate.

[0011] This allows for a better fit with subsequent assembled components.

[0012] Further preferably, a square mounting hole is provided in the center of the lower bracket, and the position of the square mounting hole is on the same straight line as the position of the rectangular slot.

[0013] It is used for assembly with other components via rectangular slots and square mounting holes.

[0014] Further preferably, the width of the square mounting hole is the same as the width of the rectangular slot.

[0015] The fit with subsequent components has been optimized.

[0016] In a further preferred embodiment, the first reinforcing rib is located between the two second reinforcing ribs.

[0017] This ensures the strength of the connection. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Reference Figure 1 and Figure 2As shown, a short-distance stepped high-voltage support includes a support body, which is a stepped iron support. The iron support includes an upper support 1, a connecting plate 2, and a lower support 3. The upper support is connected to the upper end of the connecting plate, and the lower support is connected to the lower end of the connecting plate. The connection between the upper support and the connecting plate is arc-shaped, and a first reinforcing rib 4 is provided at the connection between the upper support and the connecting plate. The connection between the lower support and the connecting plate is arc-shaped, and two second reinforcing ribs 5 are provided at the connection between the lower support and the connecting plate. The top of the upper support has an upwardly bent extension plate 6, and the end of the lower support is bent downward, with a rectangular groove 7 in the center of the end of the lower support.

[0023] This invention provides reliable structural support and installation positioning through an iron bracket, while rubber components flexibly wrap and clamp the high-voltage cables, absorbing vibration energy. This combination of rigid metal support and flexible rubber protection aims to effectively address the challenges of fixing and protecting high-voltage cable harnesses under complex operating conditions with a simple and efficient structure, thereby improving the overall reliability of the system. The bending structure enhances torsional stiffness. The elastic deformation of the rubber components can absorb more than 80% of high-frequency vibration energy, preventing wear on the cable insulation layer. The overall solution meets the IP67 protection rating while reducing weight by 40% and increasing installation efficiency by 50% compared to traditional clamps. Its standardized interface design is compatible with mainstream vehicle platforms, significantly reducing the failure rate of high-voltage systems.

[0024] Further optimization involves a circular bolt hole 8 in the center of the upper support, with the bolt hole's mounting position aligned with the extension plate's mounting position. This facilitates subsequent modular assembly.

[0025] Further optimization involves ensuring that the diameter of the bolt holes matches the width of the extension plate. This allows for a better fit with subsequent assembled components.

[0026] Further preferably, a square mounting hole 9 is formed in the center of the lower bracket, and the position of the square mounting hole is aligned with the position of the rectangular slot. The rectangular slot and the square mounting hole are used for assembly with other components.

[0027] Further optimization involves ensuring that the width of the square mounting hole matches the width of the rectangular slot. This improves the fit with subsequent components during assembly.

[0028] Further optimization involves positioning the first reinforcing rib between the two second reinforcing ribs. This ensures the connection strength.

[0029] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
