[0025] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0026] Embodiment 1

[0027] Reference Figures 1 to 5 As shown, the portable charging plug structure for a split-port lithium battery on a forklift provided in this embodiment includes a plug body 3, and the plug body 3 is connected to the battery body 2 through a power line 4, such as Figure 1 As shown, the battery body 2 is assembled in the frame 1 of the forklift. The power cord 4 has a certain length, which allows the plug body 3 to move within a certain range. Among them, a plug fixing portion 13 is provided on the shell of the battery body, and the plug body 3 and the plug fixing portion 13 are fixed by a magnetic attraction structure. In this way, when not charging or the charging cable is long enough, the plug body 3 is fixed to the plug fixing portion 13 of the battery body 2 by magnetic attraction, and the connection is firm. When charging is required and the charging cable is not long enough, the plug body 3 can be directly removed, such as by applying a certain external force to directly remove the plug body 3, and move it to the direction close to the charger for charging. There is no need to move the vehicle or find tools to remove the plug. The operation is simple and efficient, and it can be applied to a variety of working conditions.

[0028] Specifically, in this embodiment, the magnetic attraction structure includes a first magnetic attraction fitting 11 disposed on the plug body 3 and a second magnetic attraction fitting 12 disposed on the plug fixing portion 13, wherein the first magnetic attraction fitting 11 is a non-magnetic iron piece, and the second magnetic attraction fitting 12 is a magnetized permanent magnet. The first magnetic attraction fitting 11 and the second magnetic attraction fitting 12 are both rectangular block structures, that is, the first magnetic attraction fitting 11 is a rectangular iron plate, and the second magnetic attraction fitting 12 is a rectangular magnet; in this way, when the first magnetic attraction fitting 11 and the second magnetic attraction fitting 12 are attracted, the contact surface is larger and the magnetic attraction is more secure.

[0029] The first magnetic fitting 11 is locked on the plug body 3 by bolts 21. Specifically, screw holes 111 are provided at the four ends of the first magnetic fitting 11. The iron plate structure is adopted, and the screw holes 111 are easily obtained by tapping. The matching structure of the bolts 21 and the screw holes 111 is more solid and more convenient to assemble. Four bolts 21 are provided on the plug body 3, and the four bolts 21 are respectively connected to the four screw holes 111 of the first magnetic fitting 11, so as to realize the stable installation of the first magnetic fitting 11 and the plug body 3.

[0030] The second magnetic attraction fitting 12 is locked on the shell of the battery body 2 by two countersunk bolts 22. The countersunk bolts 22 can be buried in the second magnetic attraction fitting 12 without protruding from the surface of the second magnetic attraction fitting 12. Therefore, it will not affect the magnetic attraction effect of the first magnetic attraction fitting 11 and the second magnetic attraction fitting 12.

[0031] The plug fixing portion 13 is a mounting boss 131 protruding from the shell surface of the battery body 2, and the second magnetic attraction fitting 12 is locked on the mounting boss 131 by two countersunk bolts 22. The arrangement of the mounting boss 131 can ensure that the countersunk bolts 22 and the shell of the battery body 2 have sufficient connection depth and will not penetrate the shell of the battery body 2, resulting in a better assembly effect. Of course, in other embodiments, the structure of the plug fixing portion 13 is not limited to this.

[0032] This embodiment also provides a forklift, which at least includes the portable charging plug structure used for the split-port lithium battery on the forklift as described above.

[0035] At the same time, the first magnetic attraction fitting 11 can be covered in the outer shell of the plug body 3 by in-mold injection molding, so that the plug body 3 and the first magnetic attraction fitting 11 are fixedly connected.

[0036] Of course, in other embodiments, the connection between the first magnetic attraction fitting 11 and the plug body 3, and the connection between the second magnetic attraction fitting 12 and the shell of the battery body 2 can be fixed by bonding, snapping, etc.
