[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Several support rods 4 are fixedly connected to the mounting base plate 1. The two connecting shafts 3 between two adjacent positioning plates 2 share a support rod 4 and are respectively fixedly connected to the two sides of the support rods 4. Several positioning plates 2 are away from the U-shaped slot 202 at one end and close to the mounting base plate 1 at one side. Two symmetrically arranged L-shaped slots 203 are opened, and several first telescopic holes 102 are opened at the end of the mounting base plate 1 away from the connecting shaft 3. Connecting components are connected in the several first telescopic holes 102, and the other ends of several connecting components are respectively connected to the L-shaped slots 203.

[0027] like Figure 1 - Figure 5As shown, a mounting bracket for fixing the power harness of a new energy vehicle in the utility model is similar to the existing mounting bracket structure for fixing the power harness of a new energy vehicle, such as a wiring harness mounting bracket for fixing the power harness of a new energy vehicle disclosed in the patent with announcement number CN220163807U. The main improvement of the utility model is that a certain wiring harness in the mounting bracket can be disassembled and repaired separately to avoid the disorder of other wiring harnesses during maintenance, such as Figures 1 to 7 As shown, when the mounting bracket for fixing the power harness of a new energy vehicle in the utility model is used, after the mounting base plate 1 is fixedly installed, the power harness is installed in the mounting groove 101, and then the U-shaped groove 202 on the positioning plate 2 is close to the connecting shaft 3 on the mounting base plate 1, and the U-shaped groove 202 is sleeved on the connecting shaft 3, and then the positioning plate 2 is turned toward the mounting base plate 1 through the connecting shaft 3, and covered on the mounting base plate 1, so that the positioning groove 201 covers the top of the mounting groove 101, and the power harness is fixed between the mounting groove 101 and the positioning groove 201, and the connecting shaft 3 is used. The connecting assembly fixes the other end of the positioning plate 2, thereby completing the installation and fixation of a single power harness. When one of the power harnesses on the mounting base plate 1 fails or needs to be repaired, the corresponding positioning plate 2 can be removed from the mounting base plate 1 to maintain the separate power harness, thereby avoiding the scattering of other power harnesses during disassembly and affecting the maintenance work. At the same time, after completing the maintenance and inspection, it is only necessary to install and fix the disassembled power harness, and there is no need to reinstall and fix the power harnesses on other mounting base plates 1, which makes the installation operation more convenient.

[0028] like Figure 1 - Figure 6 As shown, the connecting assembly includes a pressing rod 5, a return spring 6 and an L-shaped hook rod 7. A sliding groove 103 is provided through the middle position of the first telescopic hole 102 close to one side of the positioning plate 2. One end of the return spring 6 is fixedly connected to one end of the inner wall of the first telescopic hole 102, and the other end of the return spring 6 is fixedly connected to the pressing rod 5. The pressing rod 5 is slidably connected to the first telescopic hole 102, and the L-shaped hook rod 7 is slidably connected to the sliding groove 103. One end of the L-shaped hook rod 7 is fixedly connected to one end of the pressing rod 5 close to the return spring 6, and the other end passes through the sliding groove 103 and is slidably connected to the L-shaped slot 203. When using the connecting assembly to fix the end of the positioning plate 2, the pressing rod 5 is pressed into the first telescopic hole 102, driving the L-shaped hook rod 7 to move inward, and then the positioning plate 2 approaches and rests on the mounting base plate 1. At this time, the end of the L-shaped hook rod 7 is located in the L-shaped groove 203 of the positioning plate 2. Then, the pressing rod 5 is released, and the return spring 6 drives the pressing rod 5 and the L-shaped hook rod 7 to move outward, thereby hooking the end of the L-shaped hook rod 7 in the L-shaped groove 203, and cooperating with the connection between the other end connecting shaft 3 and the U-shaped groove 202 to complete the installation and fixation of the positioning plate 2. When removing the positioning plate 2, the reverse operation can be performed.

The end of the L-shaped hook rod 7 is provided with an inclined surface, and when the positioning plate 2 is flipped downward, the edge of the L-shaped slot 203 abuts against the inclined surface of the L-shaped hook rod 7, so that without pressing the pressing rod 5, the L-shaped hook rod 7 is pressed and pushed inward through the inclined surface, so that the end of the L-shaped hook rod 7 enters the L-shaped slot 203, and is finally hooked in the L-shaped slot 203 through the action of the return spring 6, so that the installation of the positioning plate 2 on the installation base plate 1 is completed more conveniently and quickly.

[0030] like Figure 5 - Figure 7 As shown, the first extrusion assembly includes a first arc-shaped extrusion plate 8 and two first extrusion springs 9, the same end of the two first extrusion springs 9 are respectively fixedly connected to the two ends of the positioning groove 201, and the other ends of the two first extrusion springs 9 are respectively fixedly connected to the two ends of the first arc-shaped extrusion plate 8, and both ends of the first arc-shaped extrusion plate 8 do not exceed the two ends of the positioning groove 201. The two first extrusion springs 9 push and squeeze the two ends of the first arc-shaped extrusion plate 8 toward the direction of the mounting base plate 1 at the same time, thereby squeezing and fixing the internal power harness in the positioning groove 201 and the mounting groove 101.

[0031] like Figure 5 - Figure 7 As shown, both ends of the first arc-shaped extrusion plate 8 near the first extrusion spring 9 are fixedly connected with fixing rings 10, and threaded rods 11 are rotatably connected inside the two fixing rings 10. The other ends of the two threaded rods 11 penetrate the positioning plate 2 and are threadedly connected to the positioning plate 2. When the first arc-shaped extrusion plate 8 does not squeeze the internal power harness firmly, the threaded rod 11 can be rotated to push the first arc-shaped extrusion plate 8 inward through the fixing ring 10, so that it is squeezed more firmly on the power harness and the power harness is more firmly fixed.

[0032] like Figure 1 - Figure 7 As shown, one end of the threaded rod 11 away from the fixing ring 10 is fixedly connected with a hand-tightening block 12. When the threaded rod 11 is rotated, the hand-tightening block 12 can be used to more conveniently rotate the threaded rod 11.

[0033] like Figure 1 - Figure 4As shown, the second extrusion assembly includes a second arc-shaped extrusion plate 13, two extrusion rods 14 and two second extrusion springs 15. The two ends of the installation slot 101 away from the positioning plate 2 are both provided with second telescopic holes 104. One end of the two second extrusion springs 15 is respectively fixedly connected to the two second telescopic holes 104, and the other end is respectively fixedly connected to the two extrusion rods 14. The two extrusion rods 14 are respectively slidably connected to the two second telescopic holes 104, and one end of the two extrusion rods 14 away from the second extrusion springs 15 is respectively fixedly connected to the two ends of the second arc-shaped extrusion plate 13. When the power harness is installed in the installation slot 101, the power harness is placed on the second arc-shaped extrusion plate 13, and the second arc-shaped extrusion plate 13 is pushed toward the positioning plate 2 by the second extrusion spring 15 and the extrusion rod 14, and the power harness is extruded and fixed between the installation slot 101 and the positioning slot 201 in cooperation with the first arc-shaped extrusion plate 8 on the positioning plate 2.

[0034] like Figure 1 - Figure 4 As shown, an anti-slip ring 16 is fixedly connected to the outer wall of the extrusion rod 14 near one end of the second extrusion spring 15, and an anti-slip groove 105 is provided on the inner wall of the second telescopic hole 104 near one end of the second arc-shaped extrusion plate 13, and the anti-slip ring 16 is slidably connected to the anti-slip groove 105. Through the connection between the anti-slip ring 16 and the anti-slip groove 105, the second extrusion spring 15 can be prevented from pushing the extrusion rod 14 out of the second telescopic hole 104, thereby improving the connection stability of the second extrusion assembly.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
