As shown in fig. 1, the connecting device for the power storage battery 4 and the vehicle body 5 includes a first connecting member 1, a second connecting member 2, and a third connecting member 3. The first connecting part 1 is used for connecting with a power accumulator 4. The second connecting part 2 has a main body 21 arranged between the power battery 4 and the vehicle body 5, and a connecting section 22 fixed to the main body 21, the connecting section 22 being used to connect to the first connecting part 1 after passing through the upper cover 41 of the power battery 4. The third connecting member 3 is connected to the second connecting member 2 for fixing the vehicle body 5. Thus, the power battery 4 is mounted to the vehicle body 5 through the third link 3, the second link 2, and the first link 1 connected in this order in the extending direction from the vehicle body 5 to the power battery 4 for achieving the fixation of the power battery 4.
In one embodiment, as shown in fig. 2, the first connecting member 1 is configured in a rod shape. The lower end of the first connecting piece 1 is connected with a power storage battery 4. For example, the lower end of the first link 1 is connected to a lower tray beam 42 provided on the power storage battery 4. The upper end surface of the first link 1 abuts against the upper cover 41 of the power storage battery 4. An axially extending first threaded bore 11 is provided at the upper end of the first connecting piece 1 for threaded engagement with the connecting section 22. That is to say, the outer wall of the connecting section 22 is provided with an external thread, and the connecting end 22 is in threaded fit with the upper end of the first connecting piece 1 for realizing fixed connection. The arrangement is simple, easy to implement and easy to disassemble.
A first step surface 12 is provided on the first connecting member 1. The first step surface 12 faces the direction of the lower tray beam 42 of the power storage battery 4. That is, a section of the radial cross-sectional area outside the first step surface 12 near the vehicle body 5 is larger than a section outside the first step surface 12 near the power storage battery 4. By providing the first step surface 12, during the installation process, the first step surface 12 can abut against the lower tray beam 42 to play a role of limiting, the lower end of the first step surface 12 continues to extend downward and is inserted into the lower tray beam 42, and the first connecting member 1 above the first step surface 12 is disposed between the lower tray beam 42 and the upper cover 41. Thus, the first connecting member 1 of this structure is easy to install and simple in structure.
A sealing ring 13 is arranged between the upper end surface of the first connecting piece 1 and the upper cover 41 of the power storage battery 4, and is used for sealing the power storage battery 4 and avoiding water leakage into the power storage battery 4. Specifically, a mounting groove 14 is provided on the first connecting member 1. The mounting groove 14 is a circumferentially encircling groove provided between the upper end face and the outer wall face of the first connecting piece 1. The sealing ring 13 is arranged in the mounting groove 14 and sleeved on the outer wall of the upper end of the first connecting piece 1. Preferably, the mounting slot 14 is dovetail shaped such that the slot 14 extends radially inward at the slot bottom. In this form of the mounting groove 14, the sealing ring 13 can be firmly snapped into the mounting groove 14 of the first connecting member 1 during mounting, for preventing the sealing ring 13 from slipping out. When the upper end face of the first connecting part 1 approaches the upper cover 41 of the power accumulator 4, the sealing ring 13 is compressed for sealing the power accumulator 4.
