An explosion-proof control box for battery car

Abstract

The invention provides an explosion-proof type control box for an electromobile, and relates to the technical field of control boxes. The control box comprises a control box body, a control box cover, a box body mounting plate, a cable import device, an electronic control assembly and a direct current contactor; the control box body is a rectangular shell and is provided with an opening facing upwards, a bulge connection part is arranged circumferentially on the outer edge of the rectangular shell with the opening, the thickness of the bulge connection part is larger than the thickness of the wall of the rectangular shell, the control box cover is a rectangular plate matching with the bulge connection part, two pieces of box body mounting plates are mounted on one side face of the rectangular shell, several cable import devices are mounted on the other side face of the rectangular shell, four supporting heaved parts are arranged on the bottom of the inner side of the rectangular shell, supporting plates are arranged on the mounting space formed by the four supporting bulge parts, and the electronic control assembly is arranged on the supporting plates. The technical effects that the control box is applicable to multiple types of anti-explosion electromobile and the fixed mounting is facilitated by the control box are achieved.

Description

technical field [0001] The invention relates to the technical field of control boxes, in particular to an explosion-proof control box for battery vehicles. Background technique [0002] The control box is a box used to install electrical control components. It is used to prevent the internal control components from being damaged by external force impact. The existing control boxes generally only have protection functions. Generally, they are installed inside the control box Circuit breakers, contactors, magnetic starting devices, buttons and indicator lights, etc., when the control box is used in a harsh environment, explosive gas can easily damage the internal components when it enters the control box through the gap. In order to avoid the occurrence of the above situation, In actual use, the control box is set far away from the dangerous area, but once the equipment fails to cut off the power supply in time, the current explosion-proof control box applied to the battery ca...
