Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides the following technical solutions: the utility model provides an electric vehicle controller, including last protective housing 2 and lower protective housing 1, the roof of last protective housing 2 and the diapire of lower protective housing 1 are provided with buffering subassembly 6 respectively, and be connected with upper bracket 5 and lower carriage 9 on two buffering subassemblies 6 respectively, the top both sides of lower carriage 9 are fixed with U type seat 8 respectively, be provided with controller body 3 on two U type seats 8, upper bracket 5 bottom both sides are fixed with a fixed plate 4 respectively, the bottom both sides of fixed plate 4 are connected with bracing piece 7, the bottom of bracing piece 7 be fixed with one with the universal wheel 71 of U type seat 8 top contact.

The buffer assembly 6 comprises four elastic air bags 62 distributed in a circumferential array, and two ends of each elastic air bag 62 are respectively connected with a first guide pipe 61 and a second guide pipe 63, so that the gas flowing around the controller body 3 is accelerated, and the hot gas is conveniently and quickly discharged.

Vent 12 has been seted up respectively to four side outer walls of upper protective housing 2 and lower protective housing 1, and the inside embedding of vent 12 has filter screen 121, is convenient for ventilate the heat dissipation to controller body 3, reduces the entering of the dust in the air simultaneously.
