[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a BMS battery management system housing waterproof structure, such as Figure 1 , Figure 2 and Figure 3 As shown, the shell waterproof structure includes a lower shell 1, an upper shell 2 hinged on one side of the lower shell 1 for sealing the open end of the lower shell 1, a flip plate 3 rotatably mounted on the lower shell 1 for storing tools, a limit assembly arranged inside the lower shell 1 for limiting the rotation angle of the upper shell 2, and a transmission assembly arranged inside the lower shell 1 for flipping the flip plate 3.

[0026] It should be noted that the flip plate 3 is rotatably installed inside the lower shell 1, and the flip plate 3 and the lower shell 1 constitute a shell for accommodating the BMS battery management system. The side wall of the flip plate 3 is fixedly installed with a lower buckle, and the side wall of the upper shell 2 is provided with an upper buckle that matches the lower buckle, so that the upper shell 2 can seal the BMS battery management system after the cover is closed.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in order to drive the flip plate 3 to reset when the upper shell 2 is covered, the transmission assembly includes a ring 11 slidably mounted on the inner side wall of the lower shell 1, a connecting rope 8 arranged inside the lower shell 1, penetrating the lower shell 1 and connecting the ring 11 with the flip plate 3, and a mounting block 7 fixedly mounted on the inner wall of the lower shell 1 and used to limit the connecting rope 8, one end of the connecting rope 8 is fixedly connected to the radial outer wall of the ring 11, and the other end of the connecting rope 8 is fixedly connected to the side wall of the flip plate 3, and a plurality of mounting blocks 7 are provided, and the plurality of mounting blocks 7 are all fixedly mounted on the inner wall of the lower shell 1 and are all slidably connected to the connecting rope 8.

[0028] Furthermore, when the ring 11 slides downward, the connecting rope 8 is pulled to slide in the mounting block 7, and then the flip plate 3 is pulled by pulling the connecting rope 8, and the flip plate 3 rotates. When the ring 11 slides to the lowest position, the flip plate 3 is reset to overlap with the lower shell 1, and then the upper shell 2 covers the upper and lower shells 1, so that a closed chamber is formed inside the lower shell 1.

[0029] Furthermore, when the collar 11 slides upward, the connection rope 8 releases the pulling of the flip plate 3, the flip plate 3 rotates, and a notch is left in the lower shell 1, thereby increasing the operating space for the operator.

[0030] like Figure 2 and Figure 3 As shown, the limit assembly includes a connecting rod 6 whose two ends are hinged to the inner wall of the lower shell 1 and the inner wall of the upper shell 2 respectively, and a sliding block 10 slidably installed inside the lower shell 1. The sliding block 10 passes through the connecting rod 6 and extends to the interior of the lower shell 1. The ring 11 is sleeved on the radial outer wall of the sliding block 10. A sliding groove is opened inside the lower shell 1, and the inner wall of the sliding groove slides in fit with the side wall of the sliding block 10.

[0031] Specifically, when the upper shell 2 is opened from the opening of the lower shell 1, one end of the connecting rod 6 is driven to slide, and then the other end of the connecting rod 6 is pulled to slide upward on the inner wall of the lower shell 1, driving the ring 11 to slide upward, so that the flip plate 3 is flipped out of the lower shell 1, so that the flip plate 3 is driven to flip when the upper shell 2 is opened.

[0032] like Figure 5As shown, the transmission assembly further includes a pressure spring 9 sleeved on the connecting rope 8 , and one end of the pressure spring 9 is fixedly connected to the side wall of the lower housing 1 .

[0033] Specifically, when the upper shell 2 covers the lower shell 1, the connecting rope 8 pulls the flip plate 3 to squeeze the top pressure spring 9. The top pressure spring 9 has a tendency to push the flip plate 3 to rotate in real time. When the upper shell 2 is opened, the top pressure spring 9 pushes the flip plate 3 to rotate, which facilitates the use of the flip plate 3.

[0034] like Figure 3 As shown, a storage portion for storing tools is provided on the flip plate 3, and a fixing block 4 is fixedly connected to the side wall of the flip plate 3. There are multiple fixing blocks 4, and at least two fixing blocks 4 are symmetrically arranged on both sides of the storage portion. A covering plate 5 for covering the storage portion is slidably connected inside the fixed block 4.

[0035] Furthermore, the operator can place the tools required for maintenance in the accommodating portion, and slide the cover plate 5 to cover the accommodating portion, so that the tools are not easily dumped out when placed in the accommodating portion. When the upper shell 2 is opened for maintenance, the flip plate 3 rotates, and then the operator takes out the cover plate 5, which facilitates the access to the tools in the accommodating portion.

[0036] like Figure 1 and Figure 2 As shown, a sealing gasket is fixedly connected to the side wall of the flip plate 3 , which is in contact with the upper shell 2 and is used to improve the sealing performance of the inner cavity of the lower shell 1 .

[0037] Specifically, by providing the sealing gasket, the sealing performance of the inner cavity of the lower shell 1 is improved, so that the BMS battery management system is not easily invaded by water vapor, thereby extending the service life of the BMS battery management system.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
