DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] Please refer to Figures 1-6 The wire harness fixing structure of the new energy automobile motor in the embodiment includes a fixed plate 1, a rotating shaft assembly 2 is fixedly connected above the fixed plate 1, a fixed block 3 is fixedly installed above the rotating shaft assembly 2, a wire harness tube 4 is fixedly installed on the fixed block 3, and a sealing mechanism 5 is arranged on the wire harness tube 4. The rotating shaft assembly 2 is composed of a bearing, a shaft sleeve, a shaft shoulder, a key groove, and a retaining ring. The assembly can give the wire harness tube 4 the function of rotation, which is convenient for storing the wire harness on the motor of the vehicle.

[0023] The closing mechanism 5 comprises a movable cavity 501, and the inner wall of the wire harness tube 4 is provided with the movable cavity 501. The inner wall of the movable cavity 501 is slidably connected with an arc-shaped sealing plate 502. The left side of the wire harness tube 4 is provided with a clamping groove matched with the right end of the arc-shaped sealing plate 502. The right side of the arc-shaped sealing plate 502 is fixedly provided with two limiting guide plates 503 extending to the outside of the wire harness tube 4. The right side of the wire harness tube 4 is provided with two sliding grooves matched with the limiting guide plates 503. The inner walls of the two sliding grooves are slidably connected with the outer walls of the two limiting guide plates 503. The ends of the two limiting guide plates 503 extending to the outside of the wire harness tube 4 are fixedly connected with a connecting plate 504. When the wires of the automobile motor are stored in the wire harness tube 4, the staff only needs to pull the connecting plate 504 to drive the arc-shaped sealing plate 502 in the movable cavity 501 to displace. The two limiting guide plates 503 on the plate displace at the same time to guide and limit the movement of the arc-shaped sealing plate 502 to avoid displacement or jamming. When the right end of the arc-shaped sealing plate 502 moves into the clamping groove provided on the left side of the wire harness tube 4, the closing state is realized. Therefore, the design can effectively improve the effect of fixing the messy cables of the wire harness tube 4, and can also effectively prevent the escape of the cables due to shaking during the movement of the vehicle.

[0024] In the case implementation, the inner wall of the wire harness tube 4 is provided with a rubber pad 6. When the cable passes through the inside of the wire harness tube 4, the rubber pad 6 is used for transition, which can play the roles of wear resistance, waterproofness, sealing and insulation.

[0025] In the case implementation, the right end of the fixed block 3 is provided with a limiting assembly 7. The limiting assembly 7 comprises a threaded sleeve 701 and a threaded bolt 702. The right end of the fixed block 3 is provided with the threaded sleeve 701. The inner wall of the threaded sleeve 701 is threadedly connected with the threaded bolt 702. A plurality of positioning holes 101 matched with the threaded bolt 702 are uniformly provided on the fixed plate 1. By providing the threaded sleeve 701, the threaded bolt 702 and the positioning holes 101, the connection between the fixed block 3 and the fixed plate 1 can be strengthened after the angle of the wire harness tube 4 is determined.

[0026] In the case implementation, two fixing holes 102 are provided on the left and right sides of the fixed plate 1. A fixing bolt 8 is arranged on each fixing hole 102. By providing the fixing holes 102 and the fixing bolts 8, the wire harness fixing structure can be firmly connected with the body panel of the new energy vehicle, and the connection effect is also strong.

[0027] In the implementation, the following steps are performed:

[0028] 1) First, fix the fixed plate 1 with the body panel of the vehicle;

[0029] 2) Then arrange the harness on the automobile motor, and all of these harnesses are received into the harness tube 4;

[0030] 3) Then adjust the limiting assembly 7, and make the fixed block 3 and the harness tube 4 angle fixed;

[0031] 4) Finally, control the closing mechanism 5, and make the arc-shaped closing plate 502 close the opening on the harness tube 4, thus the fixing of the harness is completed.

[0032] In conclusion, the harness fixing structure of the new energy automobile motor, by setting the closing mechanism 5, when the wires of the automobile motor are received into the harness tube 4, the staff only needs to pull the connecting plate 504, and uses the connecting plate 504 to drive the arc-shaped closing plate 502 inside the movable cavity 501 to displace, and the two limiting guide plates 503 on the plate can guide and limit the movement of the arc-shaped closing plate 502 at the same time, avoiding the displacement or jamming, and when the right end of the arc-shaped closing plate 502 moves to the left side of the card slot on the harness tube 4, the closing state is realized, thus the design can effectively improve the effect of fixing the messy cables of the harness tube 4, and can also effectively prevent the escape phenomenon of the cables due to shaking when the vehicle is moving, and solves the problem that the structure uses the limiting ring to ensure that the cables in the containing part do not escape, and if used for a long time, the limiting ring will continuously rub against the surface of the cables, and this friction is easy to cause damage to the cables or the limiting ring, and once the limiting ring is damaged, the cables inside the structure will also escape.
