DETAILED DESCRIPTION

[0016] 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.

[0017] Reference Figure 1-2 A battery pack charging port protection structure includes a shell 9, one side of the shell 9 has an open groove cavity 16, the shell 9 is located on the side of the groove cavity 16 and is rotatably connected to a cover plate 11 through a second hinge 10, a magnetic attraction member is arranged between the cover plate 11 and the shell 9, the shell 9 has a first through hole 6 for a plug connector 5 to pass through, the plug connector 5 is fixed to the shell 9 through an adjustable bracket, and the adjustable bracket has at least two installation angles for installing the plug connector 5.

[0018] The device inserts the plug end of the plug connector 5 into the groove cavity 16 through the first through hole 6, and closes the groove cavity 16 through the cover plate 11, which can play a role in protecting the plug connector 5. The plug connector 5 is assembled with the shell 9 through an adjustable bracket. The adjustable bracket has at least two installation angles for installing the plug connector 5, so that the device can meet the installation requirements of the plug connector 5 at various installation angles, and is more flexible to use.

[0019] refer to Figure 2 As an embodiment, the adjustable bracket includes a support rod 1 fixed to the back of the shell 9, the end of the support rod 1 is rotatably connected to the support plate 4 through the first hinge 2, the support plate 4 is fixed to the plug connector 5 through the first fastener 3, and the plug connector 5 generally has 2-6 assembly holes when leaving the factory, generally 4, so the plug connector 5 can be fixed to the support plate 4 by bolts, and the shell 9 is provided with an adjustment plate 14 in the groove cavity 16, and the adjustment plate 14 is provided with a second through hole 15, the upper wall of the second through hole 15 abuts against the top surface of the plug connector 5, and the lower wall of the second through hole 15 abuts against the bottom surface of the plug connector 5, and the adjustment plate 14 can be adjusted up and down relative to the shell 9.

[0020] The plug connector 5 is fixed on the support plate 4, and the support plate 4 can rotate relative to the support rod 1, so the support plate 4 can be changed to different angles to adapt to different installation angles of the plug connector 5. The free end of the plug connector 5 is limited in the second through hole 15 of the adjustment plate 14. After the relative position of the adjustment plate 14 and the shell 9 is fixed, the support plate 4 will not be able to continue to rotate around the first hinge 2, that is, the relative position of the plug connector 5 and the shell 9 is fixed.

[0021] As an implementation method, the shell 9 is embedded and fixed in the battery pack body to achieve hidden installation protection.

[0022] As an implementation method for adjusting the adjustment plate 14 up and down, the shell 9 is provided with a plurality of adjustment holes 8 along the vertical direction.

The second fastener 7 is installed in different adjustment holes 8, and the plug connector 5 can be fixed at different installation angles.

[0023] The upper wall and the lower wall of the second through hole 15 are both arc-shaped surfaces, which can better adapt to the changes in different angles of the plug connector 5 and have a certain rotation margin to avoid mechanical jamming. Furthermore, the upper wall and the lower wall of the second through hole 15 are fixedly connected with elastic rubber strips, which can not only play a good sealing role, but also have a certain elastic deformation amount, further avoiding mechanical jamming when adjusting the upper and lower positions of the adjustment plate 14.

[0024] Furthermore, a piece of elastic rubber sheet is fixed on the back of the adjustment plate 14 to improve the sealing effect.

[0025] As a magnetic attraction method, the magnetic attraction part includes a magnet block 12, which is fixed on the side of the cover 11 close to the slot 16, and the magnet block 12 is arranged on the side of the cover 11 away from the second hinge 10. The shell 9 has a ferromagnetic metal part that is magnetically attracted to the magnet block 12. When the cover 11 swings down, the magnet block 12 and the ferromagnetic metal part of the shell 9 are magnetically attracted together; a handle 13 is fixed to the side of the cover 11 away from the slot 16, and the handle 13 makes it easier to open the cover 11.

[0026] As an implementation mode, the wall thickness of the shell 9 ranges from 3 mm to 6 mm. In this embodiment, the thickness of the shell 9 is 3 mm. In other embodiments, the thickness of the shell 9 can also be 3 mm, 5 mm or 6 mm, etc. It can be flexibly set according to needs and is not limited here.

[0027] As an implementation mode, the flatness of the side of the shell 9 facing the cover plate is less than 0.2, and the roughness is less than 1.6. At each assembly point, fasteners need to use waterproof glue to ensure the sealing of the hinge and the shell 9, improve the sealing of the shell 9, and then ensure the normal use of the battery pack.

[0028] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technical solution, concept, and design obtained by equivalent replacement or change based on the technical solution and utility model concept of the utility model by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
