[0002] New energy vehicles refer to automobiles that use new power systems and are driven entirely or primarily by new energy sources. They mainly include pure electric vehicles, hybrid electric vehicles, and fuel cell vehicles. Pure electric vehicles are powered entirely by rechargeable batteries and propelled by an electric motor. Hybrid electric vehicles combine a traditional internal combustion engine with an electric drive system. Fuel cell vehicles, on the other hand, generate electricity through the chemical reaction of hydrogen and oxygen to power the vehicle.

[0003] The high-voltage systems of new energy vehicles typically operate at several hundred volts or even higher, with significant current intensities. High-voltage lines generate heat during high-current transmission; if this heat is not dissipated effectively and promptly, the line temperature will continue to rise. Excessive temperature not only accelerates the aging of the line insulation materials, reducing their insulation performance and increasing the risk of short circuits, but may also cause fires.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Example: Figure 1-4 As shown in this embodiment, a safety protection device for high-voltage lines in new energy vehicles includes,

[0024] The support assembly 100 includes a fixed base 101, a fixed plate 102 fixedly connected to the end of the fixed base 101, and a support rod 103 installed at the end of the fixed plate 102.

[0025] The protective assembly 200 includes a connector 201 rotatably mounted in the middle of the support rod 103, a support column 202 fixedly mounted in the middle of the connector 201, an inner lever 203 rotatably mounted in the middle of the connector 201, and an outer lever 204 rotatably mounted at one end of the connector 201.

[0026] By adopting the above technical solution, the fixing base 101 is used to install on the support base inside the car, the fixing plate 102 is used to cooperate with the fixing base 101 to install the support rod 103, and the support rod 103 is used to cooperate to install the protective component 200. The protective component 200 can be installed in different positions along the support rod 103 as needed. At the same time, it is convenient to adjust the tilt angle of the protective component 200 along the support rod 103 to support and protect high-voltage cables of different specifications and positions. The adjustment is convenient. The connector 201 is used to connect the support column 202 to the support rod 103. The end of the support column 202 is provided with a groove structure to facilitate the locking of the cable. At the same time, the inner lever 203 and the outer lever 204 located on both sides of the support column 202 are provided on the side wall of the connector 201 to assist the support column 202 in limiting the cable and maintaining the stability of the cable position. Adjusting the position of the inner lever 203 and the outer lever 204 on the side wall of the support column 202 can adapt to the disassembly and maintenance of the cable, and can also adapt to the fixing of cables of different diameters.

[0027] Furthermore, the protective assembly 200 also includes a limiting block 205 fixedly installed at the other end of the connector 201, and a pull rod 206 rotatably installed on the side wall of the limiting block 205. One end of the pull rod 206 is engaged with the end side wall of the limiting block 205, and the other end of the pull rod 206 extends to the outside of the inner lever 203 and the outer lever 204.

[0028] By adopting the above technical solution, the end of the pull rod 206 extends to the side wall of the inner lever 203 and the outer lever 204, which facilitates the adjustment of the inner lever 203 and the outer lever 204 through the connecting parts, or fixes the inner lever 203 and the outer lever 204 to the side wall of the pull rod 206 to adapt to different usage needs.

[0029] Furthermore, the protective assembly 200 also includes a strip groove 207 provided on the side wall of the lever 206, and a handle bolt 208 movably installed in the middle of the strip groove 207. One set of handle bolts 208 is threaded to the side wall of the inner lever 203, and another set of handle bolts 208 is threaded to the side wall of the outer lever 204.

[0030] By adopting the above technical solution, a handle bolt 208 connected to the pull rod 206 is added to the side wall of the inner lever 203 and the outer lever 204. When the pull rod 206 rotates, it can be guided by the side wall groove 207 and, in conjunction with the handle bolt 208, pull the inner lever 203 and the outer lever 204 to adjust their positions, so that the inner lever 203 and the outer lever 204 can cooperate to lock the cable or release the cable.

[0031] Furthermore, the two sets of strip grooves 207 are inclined, and the length of the strip groove 207 on the outer side of the tie rod 206 is greater than the length of the strip groove 207 in the middle position.

[0032] By adopting the above technical solution, the inclined strip groove 207 facilitates the opening of the inner lever 203 and the outer lever 204, or the closing of the inner lever 203 and the outer lever 204 together, with the cooperation of the handle bolt 208, to adjust the connection status between the protective device and the cable, and adapt to the adjustment and protection of the cable.

[0033] Furthermore, the protective assembly 200 also includes a knob 209 threadedly connected to the end side wall of the pull rod 206, and the knob 209 is inserted into the side wall of the limit block 205.

[0034] By adopting the above technical solution, a knob 209 is added to the end of the pull rod 206. Tightening the knob 209 allows the end of the knob 209 to be inserted into the side wall of the limiting block 205. This allows the limiting block 205 to limit the end of the pull rod 206, maintaining the stability of the rotation angle of the pull rod 206, and thus locking the inner lever 203 and the outer lever 204 to prevent the cable from coming loose.

[0035] Furthermore, the protective assembly 200 also includes a fixing member 210 installed on one side of the support rod 103, and a support rod 211 fixedly connected to the end of the fixing member 210, the end of the support rod 211 corresponding to the position of the support rod 103.

[0036] By adopting the above technical solution, a fixing member 210 with a support rod 211 installed on the side wall of the support rod 103 is added to facilitate the support column 202 to provide further support for the wire, so that the cable can extend in different directions and maintain the stability of the cable position.

[0037] Furthermore, the protective assembly 200 also includes a locking block 212 rotatably mounted on the end of the support rod 211, and the side wall of the locking block 212 has a bent edge structure.

[0038] By adopting the above technical solution, a locking block 212 with a bent edge is added to the end of the support rod 211, which facilitates auxiliary support for the line. In particular, at the bend of the line, the locking block 212 can adjust the direction with the line, which can better support the line.

[0039] The specific implementation process of this embodiment is as follows: Adjust the position of the connector 201 along the support rod 103 so that the support column 202 installed at the end of the connector 201 is aligned with the cable. Then rotate the pull rod 206. Guided by the side wall groove 207, and with the help of the handle bolt 208, pull the inner lever 203 and the outer lever 204 to adjust their positions so that the inner lever 203 and the outer lever 204 can cooperate to hold the cable and keep the cable position stable. Then tighten the knob 209 so that the end of the knob 209 is inserted into the side wall of the limit block 205. It can cooperate with the limit block 205 to limit the end of the pull rod 206 and keep the rotation angle of the pull rod 206 stable, thereby holding the inner lever 203 and the outer lever 204 to prevent the cable from coming loose.

[0040] In summary, through the combined use of the support component 100 and the protective component 200, even in the event of partial damage or aging of the high-voltage line, the cable can be supported to prevent leakage and potential contact with high-voltage electricity by passengers and maintenance personnel, thus avoiding the risk of electric shock. In the event of a vehicle collision that exposes the line, the insulating portion at the end of the protective device can act as an isolation layer, ensuring personnel safety. It allows for proper wiring and securing of high-voltage lines, reducing friction between lines and contact with other vehicle components, thereby lowering the possibility of short circuits. The protective component installed inside the protective cover maintains the cable's routing, preventing the cable from burning due to localized overheating caused by compression, and preserving the cable's heat dissipation performance.
