DETAILED DESCRIPTION

[0019] Clearly, the described embodiments are merely a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all the other embodiments obtained by the ordinary skilled in the art without making creative labor are within the scope of protection of the present utility model.

[0020] Please refer to Figures 1-5 The utility model provides an embodiment: a detachable high voltage distribution box device installed on the power battery, including distribution box main part 1, its rear end is equipped with interface 4, can be convenient and battery pack etc connect and use, for distribution box main part 1, its inside mainly is equipped with distribution box, direct current charging interface, high voltage distribution wire harness etc., distribution box as core component, is responsible for the power battery assembly delivery electric energy distribution to each high voltage electrical equipment, and possesses high voltage loop overload and short circuit protection function, when alternating current charges, charging current will flow into power battery for its charging through distribution box, when the vehicle normal driving, current from power battery sequentially passes through direct current bus, distribution box, motor controller high voltage wire, motor controller and motor three phase wire reaches drive motor, produces driving force, more mature technology, here do not repeat, and its top fixed installation has cover plate 2 (can be fixedly connected through screw etc., can be convenient to detach and open, is convenient for internal overhaul etc. Operation), and its both ends are symmetrically welded with mounting plate 6, is connected with vertical board 5 through plug-in mechanism, vertical board 5 is welded on mounting frame 3, for mounting frame 3, only part of the diagram, it is front engine compartment or spare box etc. Position, according to the actual situation of assembling electric automobile, more mature technology, here do not repeat.

[0021] Please refer to Figures 1-5And in order to facilitate the installation and disassembly operation of the distribution box body 1 and the mounting frame 3, the quick disassembly and repair operation can be facilitated when failure occurs, which is more simple and convenient. The mounting plate 6 is symmetrically provided with a guide groove 7 of the plug-in mechanism (convenient for plug-in and pull-out operation of the positioning column 14 of the positioning mechanism), a plug-in hole 8 is formed below the guide groove 7, a plug-in block 9 is movably plugged in the plug-in hole 8, and a rubber pad 12 is attached to the end of the plug-in block 9. In order to facilitate installation and positioning, a sliding cavity 17 of the sliding assembly is formed in the vertical plate 5, a moving plate 16 is connected in the sliding cavity 17 through two springs 18, the moving plate 16 slides in the sliding cavity 17, and the end away from the spring 18 is welded and fixed with the plug-in block 9. The plug-in block 9 slides out of the sliding cavity 17, and the plug-in block 9 located outside the sliding cavity 17 and the mounting plate 6 located below the plug-in hole 8 are both provided with a positioning hole 10 of the positioning mechanism, and a positioning column 14 is plugged in the positioning hole 10.
