Problems solved by technology

[0004] The invention provides a high-voltage control box for a power electronic converter of a new energy vehicle, which has the beneficial effects of preventing bolts from being separated from threaded holes due to up and down vibrations, good anti-slip wire effect, and good fastening effect, and solves the problems mentioned in the background technology above. Under continuous vibration, the bolts will vibrate up and down, and the threaded holes are easy to slip, which makes the bolts fall off directly from the screw holes, which affects the fixing of the device

Abstract

The invention relates to the technical field of new energy automobile accessories, and discloses a new energy automobile power electronic converter high-voltage control box which comprises a base and an outer shell arranged at the upper end of the base, a built-in element is fixedly installed on the base, and a fixing mechanism is fixedly installed on one side of the outer shell. The fixing mechanism comprises an L-shaped clamping plate fixedly installed at one end of the outer shell and a connecting plate fixedly installed at one end of the base, threaded holes are formed in the L-shaped clamping plate and the connecting plate, bolts are connected into the threaded holes in a threaded mode, a rubber sleeve is further fixedly installed on the connecting plate, the rubber sleeve and the threaded holes are communicated with each other, and the connecting plate is fixedly connected with the base. An expansion opening is formed in the surface of the rubber sleeve in the circumferential direction. The inner wall of the rubber sleeve is attached to the bolt, friction force is increased, up-and-down movement of the bolt is limited, the bolt is prevented from being separated from the threaded hole due to up-and-down vibration, and the anti-thread-slipping effect and the fastening effect are good.

Description

technical field [0001] The invention relates to the technical field of new energy automobile accessories, in particular to a high-voltage control box for a power electronic converter of a new energy automobile. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. The power battery voltage of new energy vehicles is mostly 200-400V. If the high-voltage electrical appliances such as motor controller, air conditioning system, DC / DC system and charging system are directly connected to the power battery, the power battery wiring harness will be messy, which will increase the cost. It also takes up the space of the whole vehicle and increases the potential safety hazar...
