[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Example 1, please refer to Figures 1-4 A copper busbar assembly and copper busbar protective sleeve for electric vehicles, comprising: The protective cover body 100 has a protective cover 300 rotatably connected to its side via a pivot 200. The copper busbar body 400 is assembled inside the protective sleeve body 100; The protective cover body 100 is equipped with a fixing chamber 501 on its side, and the protective cover 300 is equipped with an anti-slip pad 512 on its side. A transmission plate 502 is fixedly connected to the outer side of the rotating shaft 200. By pressing your fingers on both sides of the anti-slip pad 512 and pinching the protective cover 300 through the anti-slip pad 512, you can rotate the protective cover 300 clockwise around the rotating shaft 200. This opens the protective cover 300 on the protective cover body 100. The rotating shaft 200, which rotates at a certain angle, simultaneously drives the transmission plate 502 fixedly connected to it to rotate.

[0027] The protective sleeve body 100 has a through-rotating rod 506 internally connected. A transmission component for transmission is assembled between the transmission plate 502 and the rotating rod 506. The transmission component includes a hydraulic chamber 503 that passes through the fixed chamber 501. One end of the hydraulic chamber 503 is slidably connected to a transmission rod 504 via a piston. The transmission rod 504 is located at the top of the transmission plate 502 and is fixed to the transmission plate 502. The other end of the hydraulic chamber 503 is slidably connected to a transmission rod 505 via a piston. A transmission plate 507 is fixedly connected to the outside of the rotating rod 506. The transmission plate 507 is located on the side of the transmission rod 505 and is fixed to the transmission rod 505. A limit cam 508 is fixedly connected to the top of the rotating rod 506. When the rotating rod 506 rotates, it drives the cam 508, which is fixedly connected to it, to rotate. The protruding part of the cam 508 then rotates to both sides of the copper busbar body 400 to provide isolation support for the copper busbar body 400 on both sides.

[0028] A ratchet 509 is fixedly connected to the outer side of the rotating shaft 200, and a pawl 511 is connected to the bottom of the fixing chamber 501 via a spring 510. The pawl 511 and the ratchet 509 engage. In this way, after the protective cover 300 is flipped over, the device uses the cam 508 to initially restrict the multiple copper busbar bodies 400, improving the stability of the copper busbar bodies 400 inside the protective cover body 100 after the protective cover 300 is opened.

[0029] In use, press your fingers on both sides of the anti-slip pad 512, pinch the protective cover 300 through the anti-slip pad 512, and rotate the protective cover 300 clockwise around the pivot 200. This opens the protective cover 300 on the main body 100 of the protective sleeve. The pivot 200, rotating at a certain angle, simultaneously drives the transmission plate 502, which is fixedly connected to it, to rotate. This causes the transmission plate 502 to drive the transmission rod 504, which is fixedly connected to it, to move a certain distance. In conjunction with the hydraulic chamber 503, which is slidably connected to the transmission rod 504 via a piston, the transmission rod 504, during its movement, squeezes the oil originally stored in the hydraulic chamber 503. The oil in the hydraulic chamber 503, under pressure, flows towards the side closer to the transmission rod 505, causing the transmission rod 505, which is slidably connected to the hydraulic chamber 503 via a piston, to move out of the hydraulic chamber 503. The moving transmission rod 505... The transmission plate 207, which is fixedly connected to it, moves, causing the transmission plate 207 to drive the rotating rod 1 506, which is fixedly connected to it, to rotate. The rotating rod 1 506, which is in a rotating state, can drive the cam 508, which is fixedly connected to it, to rotate. The protruding part of the cam 508 then rotates to the two sides of the copper busbar body 400, providing isolation and support for the copper busbar body 400 on both sides. When the rotating shaft 200 rotates clockwise, it can drive the ratchet 509, which is fixed to the outside of the rotating shaft 200, to rotate clockwise synchronously. As the ratchet 509 rotates clockwise, the pawl 511 can intermittently stretch the spring 1 510 to move back and forth a certain distance, thereby avoiding the teeth on the ratchet 509. Through the setting of the ratchet 509 and the pawl 511, the protective cover 300 is restricted to this state after it is opened. When it is necessary to reset the protective cover 300, the restriction on the ratchet 509 can be released by moving the pawl 511 downward.

[0030] Example 2, please refer to Figures 1-6 Based on Embodiment 1, a limiting component 600 is installed inside the protective sleeve body 100. The limiting component 600 includes a hydraulic chamber 601 that penetrates the protective sleeve body 100. One end of the hydraulic chamber 601 is slidably connected to a force-bearing rod 602 via a piston. When the protruding part of the cam 508 rotates to the positions on both sides of the copper busbar body 400, the cam 508 can press the force-bearing rod 602 and drive the force-bearing rod 602 to move downward.

[0031] One end of the hydraulic chamber 2 601 is slidably connected to an arc-shaped rod 603 via a piston, and the other end of the hydraulic chamber 2 601 is slidably connected to an arc-shaped rod 604 via a piston. A spring 2 605 is fitted to the bottom of the force-bearing rod 602, and the end of the spring 2 605 away from the force-bearing rod 602 is fitted to the inner wall of the hydraulic chamber 2 601. An inclined plate 606 is fixedly connected to the side of the arc-shaped rod 603. When the arc-shaped rod 603 extends out of the hydraulic chamber 2 601, it can drive the inclined plate 606 fixedly connected to it to move. In conjunction with the rotating cam 508, the support effect of the two inclined plates 606 on this side on the copper busbar body 400 can be expanded.

[0032] Inside the protective sleeve body 100, a support plate 608 is rotatably connected via a rotating rod 607. The support plate 608 is located on the side of the arc-shaped rod 604 and is fixed to the arc-shaped rod 604. When the arc-shaped rod 604 extends from the hydraulic chamber 601, it drives the fixedly connected support plate 608 to rotate. The support plate 608 then rotates to the side of the copper busbar body 400, providing auxiliary support for the copper busbar body 400. In this way, the stability of the copper busbar body 400 inside the protective sleeve body 100 is further improved after the protective cover 300 is opened.

[0033] In use, based on Embodiment 1, when the protruding part of cam 508 rotates to the positions of both sides of the copper busbar body 400, cam 508 can squeeze the force rod 602 and drive the force rod 602 to move downward. This, combined with the hydraulic chamber 601 which is slidably connected to the force rod 602 via a piston, causes the force rod 602 to squeeze the oil originally stored in the hydraulic chamber 601 during its downward movement. The oil in the hydraulic chamber 601, under this pressure, flows towards the side closer to the arc-shaped rod 603 and the arc-shaped rod 604. This causes the arc-shaped rod 603, which is slidably connected to the hydraulic chamber 601 via a piston, to extend out of the hydraulic chamber 601. The arc-shaped rod 603 then drives the inclined plate 606, which is fixedly connected to it, to move, coordinating with the rotated cam. 508, which can expand the supporting effect of the two inclined plates 606 on the copper busbar body 400; at the same time, the oil drives the arc rod 604, which is connected to the hydraulic chamber 601 by a piston, to extend out from the hydraulic chamber 601, and the support plate 608 is rotatably connected to the protective sleeve body 100 through the rotating rod 607, so that the arc rod 604 extending from the hydraulic chamber 601 drives the support plate 608, which is fixedly connected to it, to rotate. The support plate 608 then rotates to the side position of the copper busbar body 400, providing auxiliary support for the copper busbar body 400; when the cam 508 resets, the force rod 602 loses the effect of the cam 508 and can be reset under the action of the spring 605. Similarly, the arc rod 603 and the arc rod 604 are reset.

[0034] Example 3, please refer to Figures 1-8 Based on Embodiments 1 and 2, an auxiliary component 700 is assembled on the outer side of the protective cover body 100. The auxiliary component 700 includes a hydraulic chamber 3 701 assembled on the side of the protective cover 300. A compression block 1 702 and a compression block 2 703 are slidably connected to both sides of the hydraulic chamber 3 701 via pistons. When the protective cover 300 needs to be reset, two fingers pinch the compression block 1 702 and the compression block 2 703 from both sides. This, combined with the hydraulic chamber 3 701 which is slidably connected to the compression block 1 702 and the compression block 2 703 via pistons, causes the compression block 1 702 and the compression block 2 703 to move into the hydraulic chamber 3 701, compressing the oil originally stored in the hydraulic chamber 3 701.

[0035] A hydraulic hose 704, connected to the side of hydraulic chamber three 701, is mounted on the side of the fixed chamber 501. A hydraulic chamber four 705 is mounted on the side of the fixed chamber 501. The end of the hydraulic hose 704 away from hydraulic chamber three 701 is mounted on the top of hydraulic chamber four 705 and connected to it. A connecting rod 706 is slidably connected to the bottom of hydraulic chamber four 705 via a piston. The connecting rod 706 is located on the side of pawl 511 and is fixed to pawl 511. When the connecting rod 706 is removed from hydraulic chamber four 705, it can drive the pawl 511, which is fixed to it, to move downward, thereby releasing the pawl 511 from restricting the ratchet 509. At this time, two fingers can simultaneously pinch the protective cover 300 and rotate it counterclockwise to complete the reset, making the device more convenient to use.

[0036] In use, based on Embodiments 1 and 2, when the protective cover 300 needs to be reset, two fingers pinch the compression block 702 and compression block 703 from both sides respectively. This, combined with the hydraulic chamber 701 which is slidably connected to compression blocks 702 and 703 via a piston, causes compression blocks 702 and 703 to move into the hydraulic chamber 701, compressing the oil originally stored in the hydraulic chamber 701. The compressed oil then flows into the hydraulic hose 704, which is connected to the hydraulic chamber 701, thus pushing the oil in the hydraulic hose 704... When the hydraulic hose 704 is compressed, some of the oil inside is squeezed and flows into the hydraulic chamber 705, which is connected to the hydraulic hose 704. This causes some of the oil in the hydraulic chamber 705 to flow towards the connecting rod 706, which in turn causes the connecting rod 706, which is connected to the hydraulic chamber 705 by a piston, to move out of the hydraulic chamber 705. The connecting rod 706 then causes the pawl 511, which is fixedly connected to it, to move downward, thereby releasing the pawl 511 from the ratchet 509. At this point, two fingers can simultaneously pinch the protective cover 300 and rotate it counterclockwise to complete the reset.
