Abstract

A mobile rack type battery box is constructed to include two hollow rectangular cover shells symmetrically fastened together by screws, each cover shell having at least one longitudinal inside groove for receiving electric wires and ventilation, and a plurality of battery cells mounted in the holding space defined within the cover shells and horizontally abutted against one another.

Claims

1. A mobile rack type battery box comprising:

two symmetrical cover shells fastened together and defining a holding space, said cover shells each having a horizontal base wall, a vertical front wall, a vertical back wall, a vertical left sidewall, and a vertical right sidewall, said horizontal base wall having at least one longitudinal inside groove for receiving electric wires; and

a plurality of battery cells mounted in said holding space and horizontally abutted against one another.

2. The mobile rack type battery box as claimed in claim 1, wherein said cover shells each have an opening in the respective vertical back wall;

the opening of the vertical back wall of one of said cover shells is mounted with a power output socket for output of battery power from said battery cells;

the opening of the vertical back wall of the other of said cover shells is blocked with a sealing plate.

3. The mobile rack type battery box as claimed in claim 1, wherein the vertical left and right sidewalls of said cover shells each have a plurality of beveled ribs disposed at an inner side and adapted for friction engagement with said battery cells to hold said battery cells inside said cover shells.

4. The mobile rack type battery box as claimed in claim 1, wherein said cover shells each comprise two partition plates bilaterally inwardly protruded from the respective vertical back wall, said partition plates each having a vertical locating groove facing each other and adapted for holding a main circuit board inside said cover shells.

5. The mobile rack type battery box as claimed in claim 4, wherein said cover shells each further comprise two vertical locating grooves respectively disposed in one of said partition plate and the respective left sidewalls for the positioning of a circuit board holding said socket and a sealing plate selectively.

6. The mobile rack type battery box as claimed in claim 1, wherein the horizontal base wall of each of said cover shells has a plurality of positioning elements disposed on the inside and adapted for securing said battery cells in place.

7. The mobile rack type battery box as claimed in claim 6, where said positioning elements are upright locating rods respectively upwardly protruded from an inner side of the horizontal base wall of each of said cover shells.

8. The mobile rack type battery box as claimed in claim 1, wherein the horizontal base wall of each of said cover shells has a plurality of longitudinal ribs and longitudinal grooves alternatively arranged in parallel on the outside such that a plurality of mobile rack type battery boxes can be arranged in a stack by engaging the longitudinal ribs of one cover shell of one mobile rack type battery box into the longitudinal grooves of one cover shell of another mobile rack type battery box.

9. The mobile rack type battery box as claimed in claim 8, wherein said cover shells each have a recess disposed in the respective vertical front sidewall for the mounting of a locating plate to secure two mobile rack type battery boxes in a stack.

10. The mobile rack type battery box as claimed in claim 1, wherein said battery cells are storage battery.
