Description
New energy automobile high voltage wire harness fixed establishment Technical Field The utility model relates to the technical field of automobile wire harness fixing, in particular to a high-voltage wire harness fixing mechanism of a new energy automobile. Background In the new energy automobile industry, the high-voltage wire harness is used as a key component for transmitting electric energy, and the reliability of fixation is crucial. With the development of new energy automobile technology, the requirement for fixing the high-voltage wire harness is continuously improved, and the high-voltage wire harness fixing device is especially aimed at fixing high-voltage wires with different diameters. At present, the existing high-voltage wire harness fixing technology of the new energy automobile has obvious defects. Most fixing devices can only be adapted to high-voltage cables with specific diameter ranges, and when cables with different diameters are faced, the fixing devices with different specifications often need to be replaced, so that the operation is complex and the cost is high. This not only increases the difficulty of automobile production and maintenance, but also reduces the working efficiency. In addition, some fixed modes are not stable enough to fix the cable, and in the automobile driving process, because of factors such as vibrations influence, the cable of different diameters appears not hard up aversion easily, probably leads to the electrical connection trouble, influences the normal operating of car, brings the potential safety hazard even. In summary, the existing high-voltage harness fixing technology has the problems of poor adaptability, unstable fixing and the like in the aspect of fixing the high-voltage cables with different diameters, and a novel fixing mechanism which can flexibly adapt to the high-voltage cables with different diameters and is reliable in fixing is needed. Disclosure of utility model (One) solving the technical problems Aiming at the defects of the prior art, the utility model provides a high-voltage wire harness fixing mechanism of a new energy automobile, which solves the problems in the prior art. (II) technical scheme The high-voltage wire harness fixing mechanism for the new energy automobile comprises a fixing block, wherein a mounting hole is formed in the front side of the fixing block, a thorn shaft penetrating through the mounting hole is arranged on the fixing block, the fixing block and the thorn shaft are in rotary connection, a mounting groove communicated with the mounting hole is formed in one end of the fixing block, a worm wheel and a worm meshed with each other are arranged on the mounting groove, a rotating shaft connected with the thorn shaft is arranged on the worm wheel, the worm wheel and the rotating shaft are rotated to enable the thorn shaft to rotate, a fixing belt is arranged on the back side of the fixing block and penetrates through the mounting hole under the driving of the thorn shaft, and the fixing belt is made to form a ring shape with different diameters. Further, the top wall of the mounting hole of the fixed block is provided with a jack, the bottom wall is provided with a countersink, the thorn shaft is correspondingly provided with a through hole, and the jack, the through hole and the countersink can reach a coaxial state along with the rotation of the thorn shaft in the mounting hole of the fixed block, so that the central lines of the jack, the through hole and the countersink are overlapped.
