Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

A compact electric element bracket for a new energy battery box is shown in figure 1 and comprises a switching bracket 1 and a rectangular bracket 4; wherein, switching support 1 is installed on rectangular support 4 along the bottom, and switching support 1 passes through hexagon socket head cap screw 2 with rectangular support 4 and is connected, and switching support 1, rectangular support 4 assembly form the major structure of the neotype electric elements support of cost to be used for in the new forms of energy battery case.

Switching support 1 is the sheet metal component after the laser cutting unloading shaping of bending, can select the steel sheet, bends into the L type, and electrophoresis is done on the surface. The L-shaped structure has a wide side 1.1 and a narrow side 1.2 perpendicular to each other. As shown in fig. 3 and 4, a rectangular bracket is arranged on the narrow side 1.2 of the adapter bracket and connected with the hole 1.3, so that the adapter bracket and the rectangular bracket can be conveniently assembled; the wide edge 1.1 is provided with an electric element parallel connection hole 1.4 for installing the battery element.

The rectangular support 4 is formed by extrusion of an aluminum ingot through a die, namely an aluminum profile, and the section of the rectangular support 4 is of a rectangular cavity structure.

As shown in fig. 3 and 4, a bottom hole 4.1 of a press rivet nut is formed in the top plane of the rectangular support 4, the press rivet nut 3 is press-riveted in the bottom hole 4.1 of the press rivet nut, and the inner hexagon bolt 2 is connected with the press rivet nut 3 in a matching manner after passing through the rectangular support and connecting the hole 1.3, so that the transfer support 1 and the rectangular support 4 are assembled in a fixing manner of the press rivet nut and the inner hexagon bolt. The assembly of the inner hexagon bolt is changed from the previous sleeve wrench into the inner hexagon wrench, so that the occupation of space is reduced to a certain extent.

The inner hexagon bolt 2 is an inner hexagon fastening bolt and a standard part; the press-riveting nut 3 is a through-hole press-riveting nut and a standard part; after the pressure riveting nut 3 is pressure riveted with the rectangular support 4, the pressure riveting nut 3 is ensured not to be higher than the top plane of the rectangular support 4.

As shown in fig. 2, a fabrication hole 4.2 for assembling the press-riveting nut 3 is formed in the bottom plane of the rectangular support 4, and the fabrication hole 4.2 is an avoiding hole of a lower die used when the press-riveting nut 3 is press-riveted, so that the press-riveting nut 3 can be assembled on the rectangular support 4. The fabrication hole 4.2 is opened according to the diameter of the minimum riveting lower die, the diameter is two wall thicknesses less than the horizontal width of the rectangular support 4, the section size of the rectangular support 4 is reduced to the maximum extent, and the space is saved.

Two ends of the bottom plane of the rectangular support 4 are provided with notches 4.3 in the shape of a semicircular groove, the notches are welding process grooves, the notches in the shape of the semicircular groove enable a welding bead to move inwards, the welding size of the end is increased equivalently, and welding is firmer.

From this, it is right the utility model discloses a compact electric elements support for new forms of energy battery box compares with traditional electric elements support, has following technical advantage:

traditional electric elements support accessory contains three accessory, is C template, triangular beam, switching support respectively, and this novel electric elements support disclosed simplifies to two parts, switching support 1, rectangle support 4 promptly for the design of electric elements support is more compact, thereby can save new forms of energy battery box inner space, and more batteries can be assembled in the space-saving, and then improve the energy density of whole battery package.

For traditional electrical component accessories, a C-shaped plate and a triangular beam are required to be welded, the triangular beam and a box body are required to be welded, four welding passes are required, the welding is complicated, the occupied space of parts is large, the welding distance is too small in the limited space of a battery box, and the risk is caused during welding; and this novel electric elements support that discloses, switching support 1 adopts hexagon socket head cap screw and connects in parallel with rectangular support 4, and electric elements support's compact structure only needs to weld rectangular support 4 and box, and the welding bead reduces to the twice, simplifies the welding procedure and can also reduce the welding risk. The design of the semicircular groove-shaped notch enables the welding bead to move inwards, which is equivalent to increase the welding size of the end part, and enables the welding to be firmer.

Rectangular support 4 and switching support 1 are connected through hexagon socket head cap screw + pressure rivet nut complex mode, adopt during the assembly hexagon socket head cap spanner can, reduce occupation space to a certain extent.
