[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4The utility model provides a technical solution: a micromotor protective shell, comprising a protective shell body 1, the protective shell body 1 comprises an upper protective shell 2 and a lower protective shell 3, a plug-in board 4 is arranged at the lower end of the upper protective shell 2, a groove 5 is opened inside the side wall of the lower protective shell 3, and the plug-in board 4 is slidably embedded in the groove 5, a front protective plate 6 is arranged at the front end of the protective shell body 1, an elastic connecting member 7 is arranged at the middle position of the front protective plate 6, and the elastic connecting member 7 has a certain elastic deformation ability, a protective cavity 10 is formed inside the protective shell body 1, and a micromotor body 11 is placed in the protective cavity 10, the inner wall of the upper protective shell 2 is tightly attached to the top of the micromotor body 11, and the inner wall of the lower protective shell 3 is tightly attached to the bottom of the micromotor body 11, so as to realize the locking and fixing of the micromotor body 11, stabilize the micromotor body 11 in the protective shell body 1, protect the micromotor body 11 through the protective shell body 1, improve the structural strength of the micromotor body 11, and prevent it from being damaged under the action of external force.

[0023] Among them, the plug-in board 4 of the upper protective shell 2 is slidably embedded in the groove 5 of the lower protective shell 3, and the upper protective shell 2 can slide relative to the lower protective shell 3. When the upper protective shell 2 moves downward relative to the lower protective shell 3, the height of the protective cavity 10 is reduced, and the elastic connecting piece 7 of the front protective plate 6 undergoes corresponding elastic deformation. When the upper protective shell 2 moves upward relative to the lower protective shell 3, the height of the protective cavity 10 increases, and the elastic connecting piece 7 of the front protective plate 6 undergoes corresponding elastic deformation. By adjusting the extended length of the plug-in board 4, the height of the protective cavity 10 inside the protective shell body 1 is adjusted, and protective cavities 10 of different heights are suitable for micro-motor bodies 11 of different specifications.

[0024] The height of the protection cavity 10 can be adjusted accordingly according to the specifications of the micro-motor body 11 , so that the protection housing body 1 is suitable for micro-motor bodies 11 of different specifications and has good versatility.

[0025] The elastic connecting member 7 is provided with an opening 8 , and when the micro-motor body 11 is placed inside the protective cavity 10 , the output shaft of the micro-motor body 11 can extend out through the opening 8 .

[0026] Among them, an elastic ring 9 is arranged on the inner side of the opening 8, and the elastic ring 9 has a certain elastic force. When the output shaft of the micromotor body 11 extends through the opening 8, the elastic ring 9 relies on its own elastic force to cling to the base of the output shaft, seals the connection, improves the airtightness of the protective shell body 1, and thus improves the protective performance of the protective shell body 1.

[0027] The upper protective shell 2 and the lower protective shell 3 are fixed by a tightening member 14 .

[0028] There are two groups of tightening members 14 , and the two groups of tightening members 14 are respectively located on two sides of the protective shell body 1 .

[0029] Among them, the tightening piece 14 is a tightening screw structure. When the tightening piece 14 is loosened, the upper protective shell 2 and the lower protective shell 3 can slide relative to each other, and the height of the protective cavity 10 can be adjusted. After the adjustment is completed, the tightening piece 14 is tightened to achieve the tightening between the upper protective shell 2 and the lower protective shell 3, and the height of the protective cavity 10 can be adjusted accordingly according to the specifications of the micromotor body 11.

When wiring, the wire body passes through the rubber sleeve 13 and the wiring hole 12 and is connected with the micromotor body 11. The rubber sleeve 13 relies on its own elastic force to tightly adhere to the outside of the wire body, playing a sealing role, improving the sealing of the wiring hole 12, and then improving the airtightness of the protective shell body 1.

[0032] Among them, multiple groups of heat dissipation fins 15 are arranged on the outer surfaces of the upper protective shell 2 and the lower protective shell 3. The multiple groups of heat dissipation fins 15 increase the contact area with the air, thereby increasing the heat dissipation area, improving the heat dissipation effect of the protective shell body 1, and ensuring its heat dissipation effect while protecting the micromotor body 11.

[0033] Among them, the front protective plate 6 is fixed to the upper protective shell 2 and the lower protective shell 3 by screws. When fixing the micromotor body 11, the front protective plate 6 is removed to expose the protective cavity 10 inside the protective shell body 1. After the micromotor body 11 is fixed inside the protective cavity 10, the front protective plate 6 is installed. The front protective plate 6, the upper protective shell 2 and the lower protective shell 3 together constitute the protective shell body 1 to protect the micromotor body 11.

After the adjustment is completed, tighten the top fastener 14 to achieve the fastening between the upper protective shell 2 and the lower protective shell 3. According to the specifications of the micromotor body 11, the height of the protective cavity 10 is adjusted accordingly. The inner wall of the upper protective shell 2 is tightly attached to the top of the micromotor body 11, and the inner wall of the lower protective shell 3 is tightly attached to the bottom of the micromotor body 11. The circuit The wiring is routed through the wiring hole 12 to achieve locking and fixing of the micromotor body 11. After the micromotor body 11 is fixed inside the protective cavity 10, the front protective plate 6 is installed. The elastic connector 7 of the front protective plate 6 undergoes corresponding elastic deformation, and the output shaft of the micromotor body 11 can extend through the opening 8. The elastic ring 9 relies on its own elastic force to cling to the base of the output shaft. Multiple groups of heat dissipation fins 15 improve the heat dissipation effect of the protective shell body 1. The front protective plate 6, the upper protective shell 2 and the lower protective shell 3 together constitute the protective shell body 1 to protect the micromotor body 11.
