[0002] An electric vehicle refers to a mechatronic personal transportation vehicle that uses a storage battery as an auxiliary energy source and is installed with a motor, a controller, a storage battery, a throttle grip, a brake lever and other control components and a display instrument system on the basis of an ordinary bicycle. The electric vehicle is powered by a lithium battery. The lithium battery uses a lithium metal or lithium alloy as the anode material and uses a non-aqueous electrolyte solution. At present, in the process of using a lithium battery, in many cases, multiple lithium batteries need to be combined for use.
[0003] When the existing lithium battery for an electric bicycle is in use, there are still some problems. At present, most of the lithium batteries used do not have a connection structure during the combination process, which leads to being directly placed together at the use position. During the moving use process, collisions are very likely to occur, which is not conducive to ensuring the combination use effect and stability. At the same time, during the installation of the lithium battery box, the cover plate on its top needs to be connected by multiple bolts, which is rather troublesome during installation and disassembly.

[0009] Further, the clamping rods are symmetrically distributed at the bottom of the cover plate, and the clamping rods are movably connected inside the moving holes.
[0010] Further, the moving holes are in communication with the grooves, and the bottom of the clamping rod is located inside the positioning holes.
[0011] Further, the connecting plate is movably connected inside the installation box, and the outer diameter of the moving rod is smaller than the inner diameter of the connecting hole.
[0012] Further, the screw rod is rotationally connected to the outside of the stabilizing plate through the rotating rod, and the screw rod is meshed and connected with the threaded hole.
[0013] The beneficial effects of the present utility model are as follows:
[0014] (1) By providing the box body, when it is necessary to connect two box bodies, first, the connecting plate on the outside of the box body is clamped into the groove of another box body. At this time, the cover plate drives the sealing plate to be installed at the bottom of the box body, so that the clamping rod at the bottom of the cover plate moves downward inside the moving hole, and thus the bottom of the clamping rod is clamped in the positioning hole inside the connecting plate.

At this time, the connecting plate can be positioned. Then, the rotating rod rotates inside the rotating tube, so that the rotating rod drives the screw rod to rotate, and the screw rod is meshed and connected with the threaded hole inside the box body, thereby installing the cover plate. This installation method replaces the connection with multiple bolts, thus saving a lot of time. BRIEF DESCRIPTION OF THE DRAWINGS

A clamping rod 7 is fixedly connected to the bottom of the cover plate 2. A moving hole 8 is opened in the inner wall of the box body 1.
[0025] Specifically, as Figure 1 shown, the grooves 4 are symmetrically distributed in the inside of the box body 1. The number of the connecting plates 5 is the same as that of the grooves 4, and the two are on the same plane. The clamping rods 7 are symmetrically distributed at the bottom of the cover plate 2, and the clamping rods 7 are movably connected to the inside of the moving holes 8. The moving holes 8 are in communication with the grooves 4. The bottom of the clamping rod 7 is located in the positioning hole 6.
[0026] In this embodiment: By providing the box body 1, when it is necessary to connect two box bodies 1, first, the connecting plate 5 on the outside of the box body 1 is snapped into the groove 4 of another box body 1. At this time, the cover plate 2 drives the sealing plate 3 to be installed at the bottom of the box body 1, so that the clamping rod 7 at the bottom of the cover plate 2 moves downward inside the moving hole 8, so that the bottom of the clamping rod 7 is clamped in the positioning hole 6 inside the connecting plate 5. At this time, the connecting plate 5 inside the groove 4 can be positioned, improving the stability between the box bodies 1 and achieving the effect of preventing shaking.
[0027] Example 2 Please refer to Figure 1 、 Figure 2 and Figure 4 , the difference between this embodiment and Embodiment 1 is that: A connecting plate 9 is fixedly connected to the outside of the cover plate 2, a connection hole 10 is opened inside the connecting plate 9, an installation box 11 is fixedly connected to the outside of the box body 1, a movable pipe 12 is fixedly connected to the outside of the installation box 11, a moving rod 13 is movably connected inside the movable pipe 12, a stabilizing plate 14 is fixedly connected to the outside of the moving rod 13, a rotating pipe 15 is fixedly connected to the outside of the stabilizing plate 14, a rotating rod 16 is rotatably connected inside the rotating pipe 15, a screw rod 17 is fixedly connected to the outside of the rotating rod 16, and a threaded hole 18 is opened in the inner wall of the box body 1.
