DETAILED DESCRIPTION

[0023] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0024] like Figure 1-Figure 2 As shown, a force-controlled module motor includes a driving end 1 and a feedback end 2. The feedback end 2 is a voice coil motor. The internal energized coil is subjected to a force in a magnetic field, and the magnitude of the force is proportional to the current, thereby generating linear motion or rotational motion. In this application, the output shaft 21 of the voice coil motor performs linear motion. The driving end 1 is an encoder assembly formed by an encoder, which is used to detect the force and displacement of the voice coil motor and control the position and speed of the voice coil motor. The voice coil motor is located in a first housing 3, and the encoder assembly is located in a second housing 4, and the two are isolated from each other. The output shaft 21 of the voice coil motor is connected to the moving end 12 and is located at the front end of the voice coil motor. The encoder assembly at the front end can directly measure the initial motion state of the output shaft 21 and provide accurate starting position information. When the output shaft 21 moves, an electrical signal is generated between the moving end 12 and the fixed end 11. This can reduce interference and delay during signal transmission, more directly reflect the motion state of the output shaft 21, and reduce error accumulation in the intermediate links. At the same time, the encoder assembly at the front end facilitates inspection and calibration during installation and commissioning.

[0025] like Figure 3-Figure 5 As shown, the voice coil motor also includes two short shafts 22. The end of the output shaft 21 away from the voice coil motor penetrates the second shell 4 and is arranged on the outside. The ends of the two short shafts 22 away from the voice coil motor are located in the second shell 4 and on both sides of the output shaft 21. They play a role in enhancing the structural stability of the output shaft 21 and preventing deformation or damage caused by uneven force or vibration. They can also serve as guide shafts to ensure that the output shaft 21 maintains the correct trajectory and position during linear motion and reduces motion errors.

[0026] In this embodiment, the first shell 3 includes a first end cover 31, and the second shell 4 includes a second end cover 41. The first end cover 31 and the second end cover 41 are respectively fixed to the first shell 3 and the second shell 4 by screws. The first end cover 31 and the second end cover 41 are both removable, so that the voice coil motor can be replaced and repaired at any time, and the encoder assembly can be debugged and repaired.

[0027] To improve the stability of the voice coil motor, such as Figure 3-Figure 4As shown, the outer wall surface of the second shell 4 is provided with a mounting surface 42, and the second end cover 41 is provided with a snap-fit ​​surface 43, and the snap-fit ​​surface 43 matches the mounting surface 42. When the snap-fit ​​surface 43 is engaged with the mounting surface 42, the outer wall surface of the second end cover 41 and the outer wall surface of the first shell 3 are on the same horizontal plane. When the snap-fit ​​surface 43 is engaged with the mounting surface 42, the outer wall surface of the second end cover 41 and the outer wall surface of the first shell 3 are on the same horizontal plane, which helps to enhance the structural stability of the entire motor module. By directly connecting the encoder assembly to the output shaft 21 of the voice coil motor and locating it in the second shell 4, the voice coil motor and the encoder assembly are tightly integrated, which not only reduces the connectors and space occupied between the components, but also improves the compactness and reliability of the entire motor module. At the same time, when the encoder assembly needs to be maintained or replaced, the second end cover 41 can be easily removed without disassembling the entire motor module, thereby improving maintenance efficiency and reducing maintenance costs and potential impact on motor performance.

[0028] Furthermore, the second end cover 41 is bent at least once. Multiple bending can improve the stability of the encoder assembly in the second shell 4. The bent second end cover 41 can better cooperate with the first shell 3 to form a tighter sealing structure, optimize the contact area and shape of the second end cover 41 with the first shell 3 and the second shell 4, thereby reducing the generation of vibration and noise.

[0029] like Figure 4-Figure 5 As shown, the fixed end 11 is fixed to the second shell 4 by screws, the output shaft 21 is provided with a fixed surface 211, and the movable end 12 is provided with a fixed portion 121. The fixed surface 211 and the fixed portion 121 match and are connected by screws. By simply tightening and loosening the screws, the fixed end 11 and the second shell 4, and the output shaft 21 and the movable end 12 can be easily connected and separated, which not only simplifies the installation process but also improves work efficiency.

[0030] Furthermore, a heat dissipation area 32 is provided on the outer wall surface of the first shell 3, and the position of the heat dissipation area 32 corresponds to the position of the voice coil motor, so that heat can be directly transferred from the motor to the heat dissipation area 32, reducing the path and resistance of heat transfer. The heat dissipation area 32 corresponds to the position of the voice coil motor, making the overall structure more compact and reducing unnecessary space occupation.

[0031] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they are not intended to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
