when the reinforcing spacer 41 is positioned on top of the horizontal connecting portion 32 of the mounting bracket reinforcing rib 3, the inclined plane of the position restriction portion 412 in the reinforcing spacer 41 is flush with (i.e., aligned with) the lower outer side surface of the vertical connecting portion 31 in the mounting bracket reinforcing rib 3. Therefore, the aesthetic degree of the whole structure can be increased, and the limit limiting part 412 is prevented from protruding outwards from the vertical connecting part 31 in the mounting bracket reinforcing rib 3, so that the external cables and other articles are prevented from being collided or scratched.
In particular, an arc-shaped bent transition part 413 is respectively arranged between the horizontal gasket part 411 and each limit constraint part 412 of the reinforcing gasket 41;
the outer surfaces of the arc-shaped bent transition part 413 and the outer surfaces of the horizontal gasket part 411 and the limit restraint part 412 are smooth surfaces.
Therefore, based on the above structural design, the special-shaped mounting nut 4 with the reinforcing gasket 41 of the utility model can be conveniently and smoothly slidably mounted on the top of the horizontal connecting part 32 of the mounting bracket reinforcing rib 3, so as to improve the working efficiency, ensure the close contact between the reinforcing gasket 41 and the top of the horizontal connecting part 32 and enhance the connecting strength when the nut is connected through bolts.
In particular, the horizontal gasket part 411, the limiting and constraining part 412 and the arc-shaped bending transition part 413 of the reinforcing gasket 41 are integrally formed.
In the utility model, in the concrete implementation, the battery box body 1, the box body mounting bracket 2 and the mounting bracket reinforcing rib 3 are integrally welded.
In the present invention, the mounting bracket reinforcing rib 3 is an integrally formed structure.
It should be noted that, for the utility model, in order to ensure that the battery box can only be in a through hole state, when the mounting bolt needs to be mounted from bottom to top, the special-shaped mounting nut 4 is slidably mounted at the mounting bracket reinforcing rib 3, and after the special-shaped mounting nut 4 is perfectly matched with the mounting bracket reinforcing rib 3, the bolt is mounted, because the mounting bolt is screwed, the limit constraint part 412 is in tight contact with the vertical connecting part 31 in the mounting bracket reinforcing rib under the action of the limit constraint part 412 in the special-shaped mounting nut 4, the special-shaped mounting nut 4 cannot rotate with the mounting bolt, and the requirement of screwing the mounting bolt is met;
according to the utility model, when the requirements of customers include two installation modes of installation from bottom to top and installation from top to bottom, the box bodies of the standard box can still be in the same state, and two box body states are avoided.
The utility model can meet the requirements of the two installation modes at the same time, the standard box body installation support is directly provided with the through hole, according to the actual requirements of customers, under the condition that bolts from bottom to top are needed, the utility model can replace back-welding nuts by adopting the special-shaped installation nuts 4 and the corresponding matched structures which are externally arranged, and the battery box only needs to be designed into a box body with the installation hole as the through hole (namely the third butt joint installation hole 51).

When the bolt is installed from bottom to top, the special-shaped installation nut 4 is installed at the horizontal connecting part of the installation support reinforcing rib 3 in a sliding mode from front to back, after the special-shaped installation nut 4 is perfectly matched with the installation support reinforcing rib 3, due to the effect of the limiting and restricting part 412 in the special-shaped installation nut 4, the limiting and restricting part 412 is in tight contact with the vertical connecting part 31 in the installation support reinforcing rib, therefore, when the installation bolt is screwed, the special-shaped installation nut 4 cannot rotate along with the installation bolt, and the screwing requirement of the installation bolt is met.
2. When the bolt needs to be installed from top to bottom, the special-shaped installation nut 4 is installed at the horizontal connecting part of the installation support reinforcing rib 3 in a sliding mode from front to back, and after the special-shaped installation nut 4 is perfectly matched with the installation support reinforcing rib 3, the part, exposed out of the lower portion of the battery bracket 5, of the bolt is fixedly connected through an external fastening nut in a threaded mode. Wherein, because the heterotypic mounting nut 4 also is simultaneously with bolt screw thread fixed connection, consequently, the threaded connection intensity of bolt has been showing to increase.
