The top of the docking portion 65 is symmetrically provided with heat dissipation grooves, which is conducive to allowing external air to circulate with the interior of the lower cover body 1 to dissipate heat inside the lower cover body 1. A dustproof net 66 is embedded in the inner cavity of the heat dissipation groove, which is conducive to shielding external dust and preventing external dust or impurities from entering the interior of the lower cover body 1 at will. A square groove is provided at the bottom of the lower cover body 1, and the docking portion 65 is slidably inserted and connected to the interior of the square groove.

[0041] Working principle of the present invention: When the connection unit is in use, the first plug 7 and the second plug 8 are usually plugged into the multiple sockets respectively, and then the first clamping frame 31, the series plate 32, the second clamping frame 33 and the positioning plate 34 are connected to the upper cover 2, so that the first clamping frame 31 vertically limits the second plug 8, and the second clamping frame 33 vertically limits the first plug 7. At the same time, the positioning plate 34 and the series plate 32 are plugged into the multiple fixing plates 41, and at the same time, the operating frame 48 is pulled to move, so that the operating frame 48 pulls the connecting frame 45 to move, and the connecting frame 45 pulls the auxiliary plate 44 to move, and the auxiliary plate 44 drives the locking plate 43 to slide on the bearing frame 42, and at the same time compresses the spring 47, and the spring 47 generates elastic force on the auxiliary plate 44, and then the bearing frame 42 After being fully connected with the fixing plate 41, the operating frame 48 is relaxed. At this time, the elastic force of the spring 47 causes the auxiliary plate 44 to drive the locking plate 43 to move. The locking plate 43 is connected to the fixing plate 41 to limit the relative position of the carrier frame 42 and the fixing plate 41. At this time, the position of the positioning plate 34 is locked and the first plug 7 and the second plug 8 are locked and fixed. At the same time, the positioning frame 37 is plugged into the clamping column 54, and the position of the clamping column 54 is limited to prevent it from falling off. Then, the mounting portion 63 on the base frame body 61 is used to install it at the designated position of the vehicle. At the same time, the elastic support portion 62 elastically supports the lower cover body 1 to provide buffering protection for the lower cover body 1 and the upper cover body 2. At the same time, the docking portion 65 and the dustproof net 66 dissipate heat from the inside of the lower cover body 1.
