DETAILED DESCRIPTION

[0013] This embodiment shows a kind of electric motorcycle wire harness fixing structure, as Figures 2-5As shown, the metal bracket 21 comprises a welding portion 41 and a wrapping portion 42 located on one side of the welding portion 41, the welding portion 41 is fixedly connected with the wrapping portion 42, and the wrapping portion 42 is matched with the shape of the rubber-coated structure 2 of the wire harness in shape. In use, the welding portion 41 is fixed to the vehicle frame 1 by welding, so as to mount the metal bracket 21 on the vehicle frame 1, the welding portion 41 is located on one side of the vehicle frame 1 and is matched with the shape of the vehicle frame 1 in shape, so as to ensure the reliability of the connection, and the wrapping portion 42 is located on the side of the welding portion 41 away from the vehicle frame 1 and is matched with the shape of the rubber-coated structure 2 in shape, so as to enable the wrapping portion 42 to semi-enclose the rubber-coated structure 2.

[0014] The wrapping portion 42 is a frame structure, a support plate 44 is arranged on the middle portion of the wrapping portion 42 away from the welding portion 41, and a gap is arranged between the support plate 44 and the welding portion 41, preferably, the support plate 44 extends along the axial direction of the rubber-coated structure 2, so as to facilitate the passage of the cable tie 24 through the gap. The cable tie 24 is tightened to form a ring after passing through the bottom of the wrapping portion 42, the ring passes through the gap between the support plate 44 and the wrapping portion 42, and the wrapping portion 42 and the cable tie 24 enclose a containing space for fixing the rubber-coated structure 2. In use, the rubber-coated structure 2 is located above the support plate 44, and the cable tie 24 encloses the rubber-coated structure 2 after passing through the gap between the support plate 44 and the welding portion 41, that is, the rubber-coated structure 2 is bundled by the cable tie 24. The cable tie 24 in the embodiment is not limited, and any cable tie 24 commonly used on the market can be used as long as the parameters and performance requirements are met.

[0015] The embodiment no longer needs the bolt and the pressing plate 23 to fix the rubber-coated structure 2 of the wire harness on the vehicle frame 1, but fixes the rubber-coated structure 2 on the vehicle frame 1 by welding the metal bracket 21 on the vehicle frame 1 and bundling the rubber-coated structure 2 on the metal bracket 21 by the cable tie 24, so that the size of the metal bracket 21 can be smaller, the position of welding is lower, and the welding position can be flexibly selected. In addition, the bolt and the pressing plate 23 for fixing the rubber-coated structure 2 are no longer needed, but the rubber-coated structure 2 is bundled by the common cable tie 24, the number of mounting accessories is reduced, the mounting process is reduced, and the production cost is reduced.

[0016] The embodiment can be further improved as follows:

[0017] 1) As shown in Figure 3 and Figure 4 in order to improve the strength of the metal bracket 21, the wrapping portion 42 is provided with a reinforcing plate 43, and the reinforcing plate 43 is perpendicular to the support plate 44.

[0018] 2) As shown in Figure 5As shown, to ensure the bundling quality of the cable ties 24, the rubber-coated structure 2 is provided with a circumferentially extending limiting protrusion 25. There are two cable ties 24, located on either side of the limiting protrusion 25. This improves the bundling effect of the cable ties 24 and prevents them from tangling after crossing. Furthermore, a limiting channel matching the width of the cable ties 24 is formed between the limiting protrusion 25 and the side of the wrapping portion 42. That is, the distance between the limiting protrusion 25 and the side of the wrapping portion 42 is approximately the same as the width of the cable ties 24, thereby limiting the cable ties 24 and preventing movement and loosening caused by bumps and vibrations during vehicle operation.

[0019] 3) The welding part 41, the wrapping part 42, the support plate 44 and the reinforcing plate 43 of the metal bracket 21 are integrally molded, thereby improving the reliability of the metal bracket 21 itself and making it easy to install and disassemble.
