Of course, if the sectional shapes of the protrusion and the X-direction through hole 113 are symmetrical, the third tenons 311 at both ends of the third support rod 31 may not be reversely arranged.

As shown in fig. 2 to 10, in this embodiment, the mortise and tenon structure between the support rods is further fixed by the bolts 6. The tenon-and-mortise structure is further fixed through the bolt 6, and the splicing firmness between the supporting rods is further improved. Specifically, the spliced eye has all been seted up to two of a pair of mortise-tenon structure structurally, and after mortise-tenon structure concatenation, insert bolt 6 in the spliced eye, with two fixed structures of mortise-tenon structure. For example, in the above embodiment, the spacing of Y direction and perpendicular to battery piece coating film support plate direction between each bracing piece has been realized through tenon fourth of twelve earthly branches structure and has been fixed, through grafting bolt 6, can increase the spacing of X direction and fix, has improved the concatenation fastness, and grafting convenient operation.

Further, in the present embodiment, the plug 6 is a cylindrical plug or a U-shaped plug. The cylindrical bolt is a single bolt, and the corresponding inserting holes are one; the U-shaped bolt can be an integral structure, also can be for the one end of two cylindricality bolts to connect, forms the U-shaped structure, and the spliced eye that corresponds is two, can further improve the stability of pegging graft through the U-shaped bolt. And selecting the bolt 6 with a proper shape according to the connection form of the tenon-and-mortise structure. Of course, the shape of the plug hole can be circular, square, trapezoidal, triangular, etc., and correspondingly, the cross-sectional shape of the plug pin 6 is matched with the shape.

As shown in fig. 2-8, 10-14, 16, 17, the inner side of the modular frame is provided with a recess 7 for mounting the edge of the modular support plate 5. Specifically, the both sides face of the perpendicular to battery piece coating film support plate of bracing piece has seted up recess 7 along length direction, so sets up, and the edge grafting of modularization backup pad 5 is installed in the inside recess 7 of modularization frame, has realized the equipment of modularization backup pad 5 with the modularization frame, compares in current fixed through the screw mode, does not need special instrument to dismantle and assemble, and it is more convenient to use.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
