[0038] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0039] Example 1

[0040] This embodiment provides a protective device, including a protective cover 1 and a cover plate 3.

[0041] The protective cover 1 is installed on the frame 8. The protective cover 1 covers the outside of the MSD5 and the controller 6. The MSD5 is installed on the controller 6. The controller 6 is installed on the frame 8 through the connecting rod 7. The protective cover 1 has a through hole on its side wall for the connecting rod 7 to pass through. The protective cover 1 has a window 9 on its side wall, which is opposite to the MSD5.

[0042] For example, see Figure 1 The MSD5 is integrated into the controller 6, which is an all-in-one controller. The controller 6 is mounted on the frame 8 via two connecting rods 7, which are L-shaped. (See also...) Figure 2MSD5 and controller 6 are both located inside the protective cover 1. The protective cover 1 has two through holes on the side wall near the frame 8, which are used for two connecting rods 7 to pass through. That is, one end of the connecting rod 7 is welded to the controller 6, and the other end of the connecting rod 7 extends through the through hole to the outside of the protective cover 1 and is connected to the frame 8 by bolts.

[0043] The protective cover 1 can be an assembly of sheet metal bent parts, meaning that multiple bent plates can be assembled into a protective cover assembly using bolts. The protective cover 1 can be fixed to the frame 8 by two support rods 10. Additionally, a window 9 is provided on the side wall of the protective cover 1, see [reference needed]. Figure 3 The planar dimensions of window 9 are larger than those of MSD5, meaning that staff can fully access MSD5 through window 9, facilitating subsequent maintenance.

[0044] Cover plate 3 is installed over window 9. When no maintenance is required, cover plate 3 can seal window 9.

[0045] In summary, the protective device provided in this embodiment, by adding a protective cover 1, protects the MSD5 from corrosion by rainwater and other contaminants. Simultaneously, a window 9 is provided on the side wall of the protective cover 1, allowing the MSD5 to be exposed by opening the cover plate 3, facilitating quick disassembly of the MSD5 and providing sealing protection without hindering maintenance. Furthermore, the protective cover 1 also protects the controller 6 from the effects of rainwater and other contaminants, thus meeting the protection and usage requirements of high-voltage electrical components in new energy vehicles.

[0046] Based on the above technical solution, in the technical solution provided in this embodiment, the cover plate 3 can be hinged to the side wall of the protective cover 1. Specifically, the cover plate 3 is hinged to the side wall of the protective cover 1 via a hinge 2.

[0047] For example, see Figure 2-3 The cover plate 3 can be opened by flipping it outwards, making it convenient for staff to inspect and maintain. The cover plate 3 can be closed by rotating it until it is parallel to the side wall of the protective cover 1; the operation is simple and convenient.

[0048] Hinge 2 can be connected to the protective cover 1 and the cover plate 3 by bolts. Hinge 2 can also be connected to the protective cover 1 and the cover plate 3 by welding.

[0049] To improve the stability of the cover plate 3 when closed, a locking part 4 may be provided on the cover plate 3, and a mating part 400 adapted to the locking part 4 is provided on the side wall of the protective cover 1. See Figure 4 The locking part 4 can be a conventional locking component, such as a door lock or a push-button rotary lock.

[0050] Example 2

[0051] Based on Embodiment 1, this embodiment provides a specific implementation of the locking part 4: the locking part 4 includes a body 401, a sliding rod 402, and a spring 403.

[0052] The main body 401 is mounted on the cover plate 3. A slide 404 is provided on the side wall of the main body 401, and a slot is provided on the side wall of the mating part 400.

[0053] One end of the sliding rod 402 extends into the slide rail 404, and the other end of the sliding rod 402 is embedded in the slot. A toggle rod 406 is provided on the side wall of the sliding rod 402, and an operation hole 405 is provided on the side wall of the body 401 for the toggle rod 406 to pass through.

[0054] One end of the spring 403 is connected to the inner wall of the slide rail 404, and the other end of the spring 403 is connected to the sliding rod 402.

[0055] For example, see Figure 5 When the cover plate 3 is parallel to the side wall of the protective cover 1, the mating part 400 is located on the right side of the main body 401. A slide rail 404 extending in the left-right direction is provided on the right side wall of the main body 401, and the sliding rod 402 is slidably disposed within the slide rail 404. The left end of the spring 403 is fixedly connected to the inner wall of the slide rail 404, and the right end of the spring 403 is fixedly connected to the left end of the sliding rod 402. At this time, the spring 403 is in its natural state, and the right end of the sliding rod 402 extends into the groove of the mating part 400.

[0056] To facilitate the movement of the sliding rod 402, an operating hole 405 is provided on the side wall of the main body 401. The operating hole 405 is a strip-shaped hole extending in the left and right direction. A toggle rod 406 is provided on the side wall of the sliding rod 402. The end of the toggle rod 406 away from the sliding rod 402 extends to the outside of the main body 401 through the operating hole 405. In this way, the operator can move the toggle rod 406 from the outside, thereby moving the sliding rod 402.

[0057] Based on the above structure, when the cover plate 3 is closed, the groove of the mating part 400 limits the sliding rod 402, preventing it from rotating, and thus preventing the cover plate 3 from rotating, thus ensuring the cover plate 3 remains stable when closed. When it is necessary to open the cover plate 3, by moving the toggle lever 406 to the left, the sliding rod 402 moves upward, the spring 403 is compressed and shortened, the sliding rod 402 disengages from the groove, and the cover plate 3 can be rotated and opened. The operation is simple and convenient. When it is necessary to close the cover plate 3 again, by moving the toggle lever 406 to the left, the sliding rod 402 moves upward, and the cover plate 3 can be rotated and closed.

[0058] The operating hole 405 can also limit the movement of the lever 406, preventing the sliding rod 402 from sliding too much or even disengaging from the slide rail 404.

[0059] The end of the lever 406 may be provided with an external thread, and the side wall of the sliding rod 402 may be provided with a screw hole. The lever 406 is screwed into the screw hole for easy assembly and disassembly.

[0060] To facilitate maintenance by staff, the window 9 should be large enough, and the corresponding cover 3 should also be large. This means that a large amount of space needs to be reserved during the flipping of the cover 3; otherwise, the cover 3 cannot be opened smoothly, leading to maintenance difficulties. However, the space inside the frame 8 is usually quite narrow, and the cover 3 may interfere with other components during the outward flipping process.

[0061] To avoid the aforementioned problems, the cover plate 3 can be hinged to the side wall of the protective cover 1 via a hinge shaft 11, instead of being hinged via a hinge. For example... Figure 6 As shown, the cover plate 3 is located outside the window 9, and the hinge shaft 11 is perpendicular to the side wall of the protective cover 1, so that the cover plate 3 can rotate on a plane parallel to the side wall of the protective cover 1. This avoids the need for the cover plate 3 to be flipped outward to open, and there is no need to reserve a large space for movement.

[0062] Specifically, such as Figure 7 As shown, by moving the lever 406 to the left, the sliding rod 402 moves to the left, the spring 403 is compressed and shortened, the sliding rod 402 disengages from the slot, and the cover plate 3 can be rotated downwards to open. The operation is simple and convenient.

[0063] It is worth noting that the distance between the mating part 400 and the cover plate 3 should be large enough to avoid interference between the cover plate 3 and the mating part 400 during the rotation process.
