[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-Figure 3 As shown, the technical solution adopted by the present invention is as follows: a battery pack high and low voltage wiring harness arrangement device, comprising an inverted U-shaped upper shell 4, the top of which is fixedly connected to a first support plate 1 and a second support plate 2.

[0028] The top surfaces of the first support plate 1 and the second support plate 2 are flush, and the first support plate 1 and the second support plate 2 are symmetrical about the middle of the upper shell 4. This allows for a gap between the first support plate 1 and the second support plate 2, making it easier to place the low-voltage wiring harness between the first support plate 1 and the second support plate 2.

[0029] A pressure plate 3 is rotatably mounted on the top of the second support plate 2, one end of which is movably mounted on the top surface of the first support plate 1. The pressure plate 3 blocks the top between the first support plate 1 and the second support plate 2, thereby positioning the low-voltage wiring harness between the first support plate 1 and the second support plate 2.

[0030] The two ends of the top surface of the second support plate 2 are fixedly connected to the mounting plates, and the sides of the two mounting plates away from the first support plate 1 are extended to the outside of the second support plate 2. The pressing plate 3 is rotatably connected between the two mounting plates.

[0031] The ends of the two mounting plates away from the first support plate 1 are both rotatably penetrated by a connecting shaft 12, and one end of the two connecting shafts 12 is fixedly connected to the pressing plate 3. The pressing plate 3 can be rotated by the connecting shaft 12.

[0032] The ends of the two connecting shafts 12, away from the pressure plate 3, extend outside the corresponding mounting plate. A torsion spring is sleeved around each end of the connecting shafts 12. One end of the torsion spring is fixedly connected to the outer surface of the corresponding connecting shaft 12, and the other end is fixedly connected to the side of the corresponding mounting plate. The torsion springs act to position the pressure plate 3 on top of the first support plate 1.

[0033] A plurality of clamping blocks 8 are provided on both side surfaces of the upper shell 4 so as to be slidably spaced apart by springs 9 .

[0034] A U-shaped lower shell 5 slides inside the upper shell 4. Several positioning slots are spaced apart on both sides of the lower shell 5. These slots correspond to latches 8, one end of which is movably positioned within the corresponding slot. By positioning the latches 8 within the slots, the lower shell 5 is positioned within the upper shell 4.

[0035] Connecting blocks 10 are fixedly connected to the two outer sides of the upper shell 4 at the clamping blocks 8. A plurality of slide slots 15 are provided on both sides of the upper shell 4, each corresponding to a clamping block 8. The slide slots 15 extend into the corresponding connecting blocks 10, and the clamping blocks 8 slide within the slide slots 15.

[0036] One end of the spring 9 is fixedly connected to one side of the block 8, and the other end of the spring 9 is fixedly connected to the end surface of the corresponding chute 15. When the spring 9 is in the natural state, one end of the block 8 extends out of the chute 15.

[0037] The top of both sides of the lower shell 5 is provided with an inclined surface 7, which gradually tilts from bottom to top toward the middle of the lower shell 5. The inclined surface 7 abuts against the corresponding block 8. When the lower shell 5 is installed, the inclined surface 7 can push the block 8 to move.

[0038] One end of the clamping block 8 close to the spring 9 is coaxially fixedly connected with a slide rod 13, and the spring 9 is sleeved on the corresponding slide rod 13. The other end of the slide rod 13 slides through the end surface of the corresponding slide groove 15.

[0039] Two connecting plates 14 are rotatably provided at one end of each clamping block 8 , and the connecting plates 14 are in abutment with the outer surface of the upper shell 4 .

[0040] A rotating shaft 11 is fixedly inserted through one end of the slide bar 13 extending outside the connecting block 10. Two connecting plates 14 at the ends of the clamping block 8 are rotatably connected to the ends of the corresponding rotating shafts 11. The rotating shafts 11 enable the connecting plates 14 to rotate. The handle 6 is fixedly connected to the same side of the two connecting plates 14. When the handle 6 is in the vertical position, the rotating shaft 11 is located slightly above the center of the connecting plates 14, and one end of the clamping block 8 is located within the lower housing 5.

[0041] Working principle:

[0042] In the initial state, the handle 6 is in a vertical state and the spring 9 is in a compressed state. The spring 9 pushes the block 8 to the outside of the slide 15, and under the action of the elastic force of the spring 9, one side of the connecting plate 14 abuts against the outer surface of the upper shell 4.

[0043] When in use, place the high-voltage wiring harness in the lower shell 5. Move the upper shell 4 to the top of the lower shell 5 so that the upper shell 4 and the lower shell 5 correspond to each other. Push the upper shell 4 downward, and the inclined surface 7 will be located in the upper shell 4 first.

[0044] Inclined surface 7 contacts block 8. As upper shell 4 moves downward, inclined surface 7 compresses block 8, causing block 8 to slide toward the inside of slot 15 and compressing spring 9. Simultaneously, one end of slide rod 13 slides toward the outside of connecting block 10, causing shaft 11 to move. Connecting plate 14, no longer restrained by upper shell 4, now rotates.

[0045] The lower shell 5 is completely positioned within the upper shell 4, with the slide grooves 15 corresponding to the positioning grooves. The spring 9 pushes the block 8 toward the interior of the positioning groove, simultaneously driving the slide rod 13 to move until the connecting plate 14 continues to abut against the outer surface of the upper shell 4, thereby securing the lower shell 5 within the upper shell 4.

[0046] The pressing plate 3 is rotated so that one end of the pressing plate 3 leaves the first supporting plate 1 , and the connecting shaft 12 is rotated to twist the torsion spring.

[0047] Place the low-voltage wiring harness between the first support plate 1 and the second support plate 2. Rotate one end of the pressure plate 3 to the top of the first support plate 1. The torsion spring forces the pressure plate 3 to rest on top of the first support plate 1. This allows the pressure plate 3 to position the low-voltage wiring harness between the first support plate 1 and the second support plate 2. Separate the high-voltage and low-voltage wiring harnesses to achieve their proper arrangement.

[0048] When the lower shell 5 needs to be removed, the handle 6 is rotated to the side away from the lower shell 5. The connecting plate 14 is rotated, and the connecting plate 14 pulls the slide bar 13 to move through the rotating shaft 11, so that the block 8 slides into the inside of the slide groove 15 and compresses the spring 9.

[0049] Until the handle 6 is rotated 90 degrees and is in a horizontal position, gradually loosen the handle 6. Under the action of the elastic force of the spring 9, one side of the connecting plate 14 abuts against the outer surface of the upper shell 4. At this time, the block 8 leaves the positioning groove and is in the initial position. The upper shell 4 can be moved upward and removed.

[0050] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
