DETAILED DESCRIPTION

[0021] The utility model is further described in conjunction with the accompanying drawings and embodiments.

[0022] like Figures 1 to 4 As shown, a motor housing foot structure described in the utility model includes a housing body 1, a foot 2, a heat sink 3, a clamping block 4, a clamping groove 5, and a junction box mounting seat 6;

[0023] The shell body is installed on the foot 2; the outer surface of the shell body 1 is provided with the heat sink 3, and the heat sink 3 is evenly distributed on the outer surface of the shell body 1 in a ring shape; the shell body 1 is provided with four evenly distributed clamping blocks 4; the clamping blocks 4 are clamped on four vertical heat sinks 3; the four clamping blocks 4 are connected to form a square structure; the clamping groove 5 is provided above the foot 2; when the clamping block 4 is clamped in the clamping groove 5, the shell body 1 and the foot 2 are also fixedly connected by bolts; the top of the shell body 1 is provided with the junction box mounting seat 6. Among the four clamping blocks 4, two of the clamping blocks 4 that are not clamped with the clamping groove 5 are anti-collision structures, which further improves the protection level of the device.

[0024] The snap-in groove 5 is provided with a first step 51 and a second step 52; the snap-in block 4 is provided with a first protrusion 41 and a second protrusion 42; the first protrusion 41 is snapped on the first step 51 when the shell body 1 and the base 2 are fixed; the bottom of the second protrusion 42 abuts against the second step 52 when the shell body 1 and the base 2 are fixed; the bottom of the snap-in groove 5 and the upper end of the second protrusion 42 are respectively provided with the first threaded hole 7 and the second threaded hole 8; the first threaded hole 7 and the second threaded hole 8 are internally threadedly connected with bolts.
