Technical Field

[0001] This utility model mainly relates to the field of automotive parts technology, specifically to a wiring harness for an electric vehicle motor controller. Background Technology

[0002] Electric vehicle motor controller wiring harnesses are used to neatly separate and position multiple wires and cables, avoiding their messy distribution inside the vehicle. This makes the wiring inside the vehicle clearer and more orderly. The fasteners firmly fix the wiring harness to the vehicle body and can also prevent it from shaking or falling off during driving, ensuring the stability and reliability of the wiring harness.

[0003] Application No. CN202123211561.0 discloses an electric vehicle motor controller wiring harness, including a wire core. The wire core is provided with multiple binding components. The bottom of the binding components is provided with an installation component. The bottom of the installation component is fixedly connected to an installation plate. The binding components include an upper bracket and a lower bracket located at the upper and lower ends of the wire core, respectively. Multiple grooves are formed between the upper bracket and the lower bracket. The left and right ends of the upper bracket are fixedly connected to a first fixing block. The left and right ends of the lower bracket are fixedly connected to a second fixing block. The bottom of the second fixing block is provided with a slot. A bracket is rotatably connected between the front and rear ends of the first fixing block.

[0004] In the aforementioned prior art, multiple binding components are provided on the outer surface of the wire core, which can effectively separate and fix multiple wire cores, avoiding the high heat generated by the entanglement of multiple wire cores. However, it can only fix wire cores of a fixed specification, and its application range is small. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0030] See attached document Figure 1-5 An electric vehicle motor controller wiring harness includes a mounting frame 1, on which a plurality of wiring harness mechanisms 2 are arranged linearly. Each wiring harness mechanism 2 includes an upper wiring harness block 201 and a lower wiring harness block 202 that are distributed vertically opposite to each other. Wiring harness grooves 212 are provided at opposite ends of the upper wiring harness block 201 and the lower wiring harness block 202. The wiring harness grooves 212 are symmetrically distributed on both sides and are inclined outward in the direction from the inside to the outside.

[0031] The lower wire harness block 202 has a vertically extending first fixing rod 203 and a toothed plate 205 respectively provided on both sides of its top.

[0032] A first spring 204 is sleeved on the first fixing rod 203 to drive the upper wire bundle block 201 to slide upward on the first fixing rod 203;

[0033] The toothed plate 205 is movably connected to the movable slot 2011 opened on the upper wire harness block 201, and is locked by the snap fastener assembly 206.

[0034] In this embodiment, a cable of the motor controller is passed between the upper cable tie block 201 and the lower cable tie block 202. Then, the upper cable tie block 201 is pressed down so that it slides downward on the first fixing rod 203 until the side wall of the cable is tightly attached to the inner wall of the two cable tie grooves 212. Then, the toothed plate 205 is locked in the movable groove 2011 with the buckle assembly 206, thus completing the fixing of one cable. Similarly, the remaining cables can be fixed. The cable tie grooves 212 are symmetrically distributed on both sides and are inclined outward in the direction from the inside to the outside, so cables of different radius specifications can be fixed.

[0035] In the above embodiment, a rubber pad 207 is fitted to the inner wall of the cable tray 212 to increase the friction between the cable and the cable, prevent the cable from slipping, and also avoid damage to the cable.

[0036] The upper wire harness block 201 has a sliding groove 2012 on one side that communicates with the movable groove 2011. The buckle assembly 206 includes a movable plate 2061 that is slidably connected to the sliding groove 2012. One end of the movable plate 2061 is provided with an inclined block 2062 that matches the toothed plate 205, and the other end is provided with a baffle 2063. The baffle 2063 is slidably connected to a second fixing post 2064 symmetrically arranged on the upper wire harness block 201. A second spring 2065 is sleeved on the second fixing post 2064 to drive the baffle 2063 to slide inward on the second fixing post 2064.

[0037] In this embodiment, when the upper cable bundle block 201 is pressed down and slides downward on the first fixed rod 203, the first spring 204 is stretched downward, and the inclined block 2062 moves downward simultaneously. The teeth of the toothed plate 205 push against the inclined block 2062, so that the inclined block 2062 moves outward in the slide groove 2012 and leaves the teeth. At this time, the second spring 2065 is compressed. When the inclined block 2062 is aligned with the teeth again, the compressed second spring 2065 returns to its original state, which can drive the inclined block 2062 to lock into the teeth. Similarly, repeating the above steps can lock the upper cable bundle block 201 at different heights, thereby adapting to cables of different radii. In addition, the upper cable bundle block 201 can be driven upward by the first spring 204 to make the locking effect better.

[0038] The bottom of the lower wire harness block 202 is fixedly installed with a connecting sleeve 208. The connecting sleeve 208 is slidably connected to the mounting frame 1. The mounting frame 1 has a plurality of first positioning holes 101 arranged in a linear pattern. The first positioning holes 101 and the second positioning holes 2081 on the connecting sleeve 208 are matched with each other and are jointly equipped with positioning screws 209.

[0039] In this embodiment, after the connecting sleeve 208 slides on the mounting bracket 1, when the second positioning hole 2081 aligns with one of the first positioning holes 101, the positioning screw 209 can be installed into the two aligned positioning holes to lock it in the current position. Similarly, it can be locked in other positions, thereby enabling the adjustment of the spacing between two adjacent cable harnesses 2, which is used to adjust the spacing between two adjacent cables according to the actual situation.

[0040] The top of the upper cable bundle 201 is provided with a fixing plate 210. The fixing plate 210 is made of transparent material and has a slot 2101 on the top. A writing board 211 is inserted into the slot 2101. The writing board 211 is marked with the corresponding label of the cable, so that multiple cables can be quickly identified and distinguished.

[0041] The mounting bracket 1 has mounting base plates 102 fixedly installed at both ends of its bottom, which are used to install the device in the corresponding position on the car by screws.

[0042] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.

[0043] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art.
