Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage cabinets for automotive hybrid power testing, and more specifically, it relates to a high-voltage cabinet for automotive hybrid power testing. Background Art

[0002] In the existing technology, there are some inconveniences in the operation of high-voltage cabinets for automotive hybrid power testing, especially when connecting to the outside world. These inconveniences are mainly reflected in two aspects.

[0003] Firstly, the existing high-voltage cabinets for automotive hybrid power testing need to be connected to multiple cables during use. These cables undertake the important task of transmitting high-voltage electric energy to ensure the accuracy and effectiveness of the test. However, due to the large number of cables and the complex connection method, the existing equipment cannot be conveniently fixed. This results in problems such as loosening, poor contact, or short circuit of the cables during use, thus affecting the stability and safety of the test. In addition, the unstable connection of the cables may also pose a safety hazard to the operators, especially in a high-voltage environment. Once an accident occurs, the consequences will be unimaginable.

[0004] Secondly, the inconvenience of the existing high-voltage cabinets for automotive hybrid power testing in fixing multiple cables is also reflected in the maintenance and replacement of the equipment. Due to the complex cable connection, when a certain cable needs to be replaced or repaired, the operator needs to spend a lot of time and energy for disassembly and assembly. This not only reduces the work efficiency but also may increase the risk during the operation. Especially in an emergency, this inconvenient fixing method may pose a threat to the safety of the operator. Content of the Utility Model

[0030] Please refer to Figures 1-5, A high-voltage cabinet for automotive hybrid testing, comprising a cabinet body 1 and a top plate 2. The top plate 2 is installed on the cabinet body 1. A fixing mechanism is provided on the top plate 2. The fixing mechanism includes a fixing sleeve 3, a return mechanism, a shrinkage sleeve 4, a slider 5, a push plate 6, a rubber strip 7, a push rod 8, a spring 9 and a pushing mechanism. There are multiple fixing sleeves 3, and the multiple fixing sleeves 3 are respectively installed on the top plate 2. The return mechanism is installed on the fixing sleeve 3. The shrinkage sleeve 4 is installed in the fixing sleeve 3. The slider 5 is slidably connected in the shrinkage sleeve 4. One end of the spring 9 is connected to the slider 5, and the other end of the spring 9 is connected to the push plate 6. Multiple rubber strips 7 are installed on the push plate 6, and the rubber strips 7 abut against the side wall of the cable. And a top hole 10 and a bottom hole 11 are formed on the push plate 6. The top hole 10 and the bottom hole 11 are respectively threadedly connected with the push rod 8. The pushing mechanism is installed on the fixing sleeve 3. The return mechanism includes a receiving sleeve 12, a return spring 13 and a push sleeve 14. The receiving sleeve 12 is fixedly installed on the side wall of the fixing sleeve 3. The return springs 13 are respectively connected between the receiving sleeve 12 and the push sleeve 14. The push sleeve 14 is slidably connected to the fixing sleeve 3. Multiple vertical grooves 15 are formed on the side wall of the fixing sleeve 3. A push block 16 is slidably provided in each vertical groove 15. The push block 16 is installed on the slider 5. The push sleeve 14 abuts against the multiple push blocks 16. Multiple scales 17 are equidistantly formed on the side wall of the fixing sleeve 3. The push sleeve 14 fits on the scales 17. The pushing mechanism includes a compression spring 18 and a thrust bearing 19. A compression spring 18 is installed on each slider 5. The thrust bearing 19 is slidably installed in the fixing sleeve 3. The compression spring 18 abuts against the thrust bearing 19. A threaded pipe 20 is threadedly provided in the fixing sleeve 3. The threaded pipe 20 abuts against the thrust bearing 19. A hexagonal groove 21 is formed on the side wall of the threaded pipe 20. Multiple fitting springs 22 are provided in the threaded pipe 20. The multiple fitting springs 22 respectively fit on the side wall of the cable. A base 23 is provided on the lower end surface of the cabinet body 1. The base 23 is installed on an external device.

[0031] In this embodiment, when the cable needs to be fixed, first pass the cable through the fixing sleeve 3, then rotate the threaded pipe 20 to make the slider 5 slide along the shrinkage sleeve 4 through the thrust bearing 19 and the compression spring 18, and then make the multiple push plates 6 approach each other, so that the rubber strips 7 abut against the side wall of the cable. When stable fixing is required, only need to install the push rod 8 in the inner bottom hole 11. As the push plate 6 fits against the side wall of the cable, at this time the push rod 8 abuts against the slider 5, and the spring 9 at the position of the bottom hole 11 cannot expand or contract, so pressure will be applied at this point, thus ensuring effective fixing. When the cable is pulled outwards, there will be a greater resistance, thus ensuring the stability of the fixing. And the corresponding position can be observed through the scale 17, thus ensuring the stability of the fixing. When it needs to be untied, only need to loosen the threaded pipe 20, and the convenience of untying can be ensured by the return spring 13.

[0032] More specifically, when conducting automotive hybrid testing, first place the corresponding components into the cabinet 1 for connection. Therefore, external cable power supply is required. Then fix the cable to carry out the corresponding testing process.

[0033] In summary, when the overall equipment is in use or operation: when it is necessary to fix the cable, first pass the cable through the fixing sleeve 3, and then rotate the threaded pipe 20 to make the slider 5 slide along the shrinkage sleeve 4 through the thrust bearing 19 and the compression spring 18. Then make the multiple push plates 6 approach each other, so that the rubber strip 7 abuts against the side wall of the cable. When stable fixation is required, only need to install the ejector rod 8 in the inner bottom hole 11. As the push plate 6 fits against the side wall of the cable, at this time the ejector rod 8 abuts against the slider 5, and the spring 9 at the position of the bottom hole 11 cannot expand or contract. Therefore, pressure will be applied at this point, thus ensuring effective fixation. When the cable is pulled outwards, there will be a greater resistance, thus ensuring the stability of the fixation. And the corresponding position can be observed through the scale 17, thus ensuring the stability of the fixation. When it is necessary to untie, only need to loosen the threaded pipe 20, and the return spring 13 can ensure the convenience of untying.

[0034] When conducting automotive hybrid testing, first place the corresponding components into the cabinet 1 for connection. Therefore, external cable power supply is required. Then fix the cable to carry out the corresponding testing process.
