[0002] Currently, the structure of a servo motor mainly includes a rotor, stator, encoder, etc. When using a servo motor, it is necessary to connect the servo motor to a driver. The encoder inside the servo motor feeds back signals to the driver, and the driver adjusts the motor speed and torque according to the feedback value and the target value.
[0003] However, existing modular servo motors do not have corresponding protective structures during use. For example, China has authorized a modular integrated servo motor with the following utility model publication number: CN218771659U: This motor includes a motor body module, a drive module, and a motor component module that are electrically connected to each other. The drive module includes a driver and a driver housing. The driver is located inside the driver housing, and the driver housing has mounting holes. The drive module is detachably connected to the motor body module and the motor component module through the mounting holes. The motor component module includes multiple motor components, and the motor component module is detachably connected to the motor body module.
[0004] The modular servo motors in the above-mentioned existing technologies lack corresponding protective structures, which limits the application environment of the servo motors. For example, they are not suitable for use in confined spaces or liquid environments. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0023] Please see Figure 1-3This utility model provides a technical solution: a servo motor based on a modular assembly structure, including a base 1, a servo motor 2, a protective housing 3, and a top protective plate 7. A through groove 14 is formed on the top of the base 1, and a shock-absorbing pad 13 is adhered to the bottom of the through groove 14. The servo motor 2 is placed on top of the shock-absorbing pad 13, which dampens the vibration of the servo motor 2 and protects it. The protective housing 3 is fitted onto the outer surface of the servo motor 2. An extension plate 11 extends from the bottom outer surface of the protective housing 3, and the bottom of the extension plate 11 contacts the top of the base 1. A slot 15 is formed on the top of the base 1, located on the outer surface of the through groove 14. A locking block is engaged within the slot 15, and the top of the locking block is fixedly connected to the bottom of the extension plate 11. The top of the protective housing 3 is engaged with the top of the top protective plate 7, and the bottom of the top protective plate 7 contacts the top of the servo motor 2. An mounting bracket is fixedly connected to both ends of the protective housing 3. Mounting plate 5 is connected to base 1 by fixing bolts 6. After the servo motor 2 is assembled, it is placed on base 1, and then the servo motor 2 is fitted with protective housing 3. During use, the protective housing 3 is locked in place by a locking block in slot 15 to improve its sealing performance. An extension plate 11 is provided at the bottom of the protective housing 3. The extension plate 11 keeps the gap between base 1 and protective housing 3 away from the servo motor 2. A drainage groove 4 is provided on base 1 at slot 15. When used in a liquid environment, the existing technology generally sets a mounting base to prevent the bottom of the servo motor 2 from contacting the ground. Therefore, the drainage groove 4 will not come into contact with the liquid. However, there is water vapor in the environment. When water vapor enters from the gap between extension plate 11 and base 1, it can be drained out from the drainage groove 4 to protect the main body of the servo motor 2.
[0024] Please see Figure 1 This utility model provides a new embodiment in which the protective housing 3 has a notch at the bottom of the output shaft end of the servo motor 2. The notch is a groove opened from the bottom to the top. By opening the notch, the output shaft is not stuck after the protective housing 3 is fitted onto the surface of the servo motor 2. However, considering that the servo motor 2 will be exposed at the notch, waterproof coating can be applied here after assembly.
[0025] Please see Figure 2 This utility model provides a new embodiment in which an arc-shaped extension plate 8 is fixedly connected to the top of the top protective plate 7. The arc-shaped extension plate 8 has bent portions 10 at both ends, and several reinforcing ribs 9 are provided at the bottom. By setting the top protective plate 7 on the top of the servo motor 2, as... Figure 2As shown, the top protective plate 7 is arc-shaped, which can guide falling objects to the side of the base 1 and protect the servo motor 2. The bottom of the arc-shaped extension plate 8 is provided with reinforcing ribs 9 to improve the strength of the top protective plate 7. The setting of the bending part 10 can not only prevent assembly personnel from being scratched during assembly and make it easier for assembly personnel to pick up, but also further improve the strength of the top protective plate 7.
[0026] Please see Figure 2 This utility model provides a new embodiment in which a sealing strip 12 is provided at the gap between the extension plate 11 and the base 1, and waterproof sealing is achieved by the sealing strip 12, so that the servo motor 2 can be better used in different environments.
[0027] Working principle: During assembly, the assembler assembles the servo motor 2 using existing technology, then places the servo motor 2 into the through slot 14 of the base 1, and then fits the servo motor 2 into the protective housing 3. At this time, the protective housing 3 will be snapped into the base 1. Then, the protective housing 3 is fixed to the base 1 by fixing bolts 6. Finally, the top protective plate 7 is inserted above the protective housing 3, thus completing the assembly of the servo motor 2.
[0028] Finally, apply waterproof coating to the gaps to complete the final assembly.
[0029] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
