And a matched structure is arranged below the vehicle body bottom plate assembly 1 corresponding to the positions of the battery box hanging points and the connector. The battery box connector assembly of the present invention is provided on a vehicle body floor assembly 1. Shown as a female connector 3. Due to the error existing in the processing and installation of the bottom plate assembly of the vehicle, the connection of the hanging point part is usually ensured in the connection process of the battery box and the bottom plate assembly, the deviation exists between the connector male head 23 and the connector female head 3 on the bottom plate assembly in sequence, and the multi-degree-of-freedom adjustment of the connector female head 3 is allowed during the installation.
The male and female connector structures are conventional. The female connector 3, as shown in fig. 7, includes the terminals 31, the terminals 311, and the guide sleeve 312, which are embedded in, rigidly connected to, and fixed to a mounting plate 313 for fixing the terminal assembly, as in the prior art, to form a single body. The rectangular shape of the holder plate 313, rather than the circular shape or other shapes, is advantageous in that both the simplification of the structure and the prevention of the rotation of the terminal 31 along the axis can be achieved.
As shown in fig. 3, 10 and 11, the connector bracket plate 4 of the assembly of the present invention in one embodiment is welded under the underbody panel 6.

Forming a basin-like structure. In the first rubber ring sleeve 32 embedded in the peripheral edge of the support plate 313, a clamping groove 39 for clamping the support plate is arranged on the inner wall of the first rubber ring sleeve 32. The clamping groove 39 is U-shaped in section. Three sides can be compressed, so that the rectangular plate of the terminal can move in small amplitude in front, back, left, right, up and down directions. In order to facilitate the installation of the bracket plate 313 clamped in the clamping groove 39, the first rubber ring sleeve comprises at least two parts which are spliced. The splicing part can be a left splicing part, a right splicing part, a front splicing part, a rear splicing part or an upper splicing part and a lower splicing part, and the diagram shows the front splicing part and the rear splicing part. In the embodiment shown, the first rubber ring 32 is rectangular.

I.e. the first rubber ring sleeve is thicker or higher than the second rubber ring sleeve. When the torsion of an X axis and the torsion of a Y axis occur, the first rubber ring sleeve is extruded to deform at the beginning, and when the upper end face of the second rubber ring sleeve is attached to the bottom plate of the connector support plate, the reaction force (torque) of the rubber ring sleeve is increased, so that the overlarge torsion is avoided.
As shown in fig. 9, a section a is taken along a middle wiring position and a section B is taken along a guide sleeve position in order to mount the female connector 3 on the connector bracket plate 4 welded to the underbody.
As shown in fig. 10, the cross section a-a has a structure in which the support plate 313 is embedded around the terminal 311, the first rubber ring 32 is engaged with an edge of the rectangular plate 313, and the first rubber ring is in a U shape that is laid down. There is a gap between second rubber ring 33 and first rubber ring 32.
As shown in fig. 11, section B-B is configured such that guide sleeves 312 are fitted into corresponding holes in rectangular plate 313.
As shown in fig. 8, when the battery box is installed in the vehicle body, the male connector 7 of the battery box is engaged with the female connector 3 fixed to the underbody connector. Even if there is a small amount of positional deviation between the male connector 7 and the female connector 3, as long as the guide pin on the male connector 7 and the guide sleeve on the female connector 3 can be installed in a matching manner first, a small amount of deviation of 6 degrees of freedom can be allowed between the female connector 3 and the connector bracket plate 4 on the vehicle body floor under the elastic deformation of the rubber sleeve 32 and the rubber ring 33, and then the smooth plugging and unplugging between the male connector 7 and the female connector 3 can be realized.
The connector disclosed by the invention has the advantages that the male connector is arranged at the end of the battery box, the female connector is arranged at the end of the vehicle body, the waterproof performance and the drainage function are better, and the risk of water accumulation is avoided.
The connector female head structure can generally realize a slightly larger deviation of the terminal along the X, Y direction, a slightly smaller deviation along the Z direction and a small amount of torsion or rotation around the X, Y, Z direction, namely, the requirement of smooth installation under the condition of a small deviation of 6-degree-of-freedom direction between the connector female head and the male head in the installation process of a power battery box is met. It is also desirable that the connector meet a greater amount of deflection in the direction X, Y and a lesser amount of deflection in the direction Z during actual installation. Further, the offset in the Z direction is controlled by the thickness of the two sides of the first rubber ring sleeve 32 with the U-shaped cross section and the compression performance of the rubber, and the offset in the X, Y direction is controlled by the allowable compression amount caused by the cross section thickness of the rubber ring 33 and the shape of the boss, and is also influenced by the allowable compression amount of the rubber in the middle section of the rubber ring sleeve 32 with the U-shaped cross section, so that the offset in the X direction and the Y direction can meet the offset of not more than 6 mm, the offset in the Z direction of not more than 3 mm and the torsion of 1-3 degrees.
