[0024] Please see Figure 1 , Figure 2As shown, the miniature motor driver provided in this embodiment includes a housing with a rectangular structure. The housing includes a first plate 110 and a second plate 120 spaced apart and opposite to each other. The first plate 110 is provided with a positioning groove 111, which is located on the side of the first plate 110 and forms an opening on the side of the first plate 110. The second plate 120 is provided with a plurality of line ports 121. The positioning groove 111 is used to determine the assembly position when installing the miniature motor driver. The first plate 110 is provided with four positioning grooves 111, two of which are located on the side of the first plate 110 near the fifth plate 150, and the other two are located on the side of the first plate 110 near the sixth plate 160, providing positioning on both sides of the first plate 110.

[0025] According to a specific embodiment of this application, the housing further includes a third plate 130, a fourth plate 140, a fifth plate 150, and a sixth plate 160 that are perpendicular to the first plate 110 and the second plate 120. The third plate 130 and the fourth plate 140 are arranged opposite each other, and the fifth plate 150 and the sixth plate 160 are arranged opposite each other. The first plate 110, the second plate 120, the third plate 130, the fourth plate 140, the fifth plate 150, and the sixth plate 160 together form a rectangular structure, which occupies a small overall space and facilitates the design of the installation location.

[0026] According to a specific embodiment of this application, a strip-shaped post 180 is provided between any two adjacent plates of the third plate 130, fourth plate 140, fifth plate 150, and sixth plate 160. The strip-shaped post 180 has a fan-shaped cross-section and an arc-shaped surface 181, with the arc-shaped surface 181 facing outwards from the housing. The strip-shaped post 180 rounds the corners of the housing, reducing the volume at the corners and preventing scratches to the operator or other wiring.

[0027] According to a specific embodiment of this application, a recessed groove 170 is provided on the fifth plate 150 and the sixth plate 160. The recessed groove 170 includes a bottom wall 171 located at the bottom of the recessed groove 170 and side walls 172 located around the bottom wall 171. The side walls 172 near the third plate 130 and the fourth plate 140 are inclined relative to the third plate 130 and the fourth plate 140. By providing the recessed groove 170, the volume of the housing is further reduced. At the same time, when installing the small motor driver, the housing needs to be positioned by screws or studs in conjunction with the positioning groove 111. The recessed groove 170 provides assembly space for the screws or studs, so that after the small motor driver is assembled, the screws or studs are hidden in the recessed groove 170, saving space.

[0028] According to a specific embodiment of this application, first heat dissipation grooves 190 are provided at intervals on the third plate 130 and the fourth plate 140, with the first heat dissipation grooves 190 located near the first plate 110. According to a specific embodiment of this application, second heat dissipation grooves 191 are provided on the fifth plate 150 and the sixth plate 160, extending to the side wall 172. According to a specific embodiment of this application, third heat dissipation grooves 192 are provided at intervals on the strip column 180 near the first plate 110, and the third heat dissipation grooves 192 communicate with the corresponding adjacent second heat dissipation grooves 191. The arrangement of the first heat dissipation grooves 190, the second heat dissipation grooves 191, and the third heat dissipation grooves 192 improves the heat dissipation effect of the small motor driver.

[0029] According to a specific embodiment of this application, four first positioning holes 151 are spaced apart on the fifth plate 150. The first positioning holes 151 are used to position the housing by engaging studs during assembly. According to a specific embodiment of this application, four second positioning holes 161 are spaced apart on the sixth plate 160. The second positioning holes 161 are used to position the housing by engaging studs during assembly. The four first positioning holes 151 and four second positioning holes 161 further position the housing on the fifth plate 150 and the sixth plate 160 to facilitate the installation of a small motor driver.

[0030] In summary, the small motor driver in the embodiments of this application has a simple overall structure, small size, small footprint, and is easy to install. The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
