[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0025] REFERENCE Figures 1-3The utility model provides a kind of waterproof structure of electric vehicle controller, including base 1, the outer wall of both sides of base 1 is fixedly connected with mounting bracket 2, the inside of base 1 is provided with four groups of electric capacity, and top is provided with corresponding terminal, the surface of mounting bracket 2 is equipped with two groups of annular grooves, and inside detachably installed bolt, so that cooperation bolt can be fixed in the inside of electric vehicle, the surface of two mounting brackets 2 is detachably installed with upper cover 4 by quick release assembly 3, the surface of upper cover 4 is equipped with the empty slot of fitting socket 5, so that when the whole of upper cover 4 is installed, it can be just connected in the outside of socket 5, the bottom end of base 1 inner wall is provided with three sockets 5.

[0026] Referring to Figure 2 And Figure 3 The surface of upper cover 4 is equipped with glue pouring port 6, by being equipped with glue pouring port 6 and by injecting colloid into the cavity formed by base 1 and upper cover 4, so that waterproof space can be formed by using colloid.

[0027] Referring to Figure 1 And Figure 3 Quick release assembly 3 includes fixed block 31, the side wall of fixed block 31 is elastically connected with clamping block 33 by tension spring 32, clamping block 33 is rotatably connected to the inside side wall of fixed block 31, one end of tension spring 32 is clamped to the outside side wall of fixed block 31, the other end of tension spring 32 is clamped to the side wall of the top end of clamping block 33, the effect of tension spring 32 is to automatically reset after clamping block 33 rotates around fixed block 31 to remove the clamping limit of positioning block 34, the side wall of the bottom end of clamping block 33 is clamped with positioning block 34, the clamping between the two, so that upper cover 4 and base 1 can be quickly spliced, so that the inside is in a sealed state, and the quick release structure can quickly open upper cover 4 to overhaul the inside of base 1.
