[0022] In the embodiment of the utility model, the directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings), if the specific posture changes, the directional indications also change accordingly.

[0023] In addition, in the utility model, the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one feature.

[0024] Please refer to Figures 1-4 The automobile shock-absorbing motor of the embodiment of the present utility model is composed of a motor mover 10 and a motor stator 20.

[0025] The motor rotor 10 includes a motor shaft 11, a magnetic ring 12, a motor coil 13, and a guide sleeve 14. The motor coil 13 is mounted on the motor shaft 11 via the magnetic ring 12. The guide sleeve 14 is sleeved onto the motor shaft 11, covering the motor coil 13 inside.

[0026] The motor stator 20 includes a motor housing 21, a motor magnet 22, and a guide inner cylinder 23. The guide inner cylinder 23 is disposed within the motor housing 21, and the motor mover 10 is mounted on the guide inner cylinder 23. The motor magnet 22 is disposed between the guide inner cylinder 23 and the motor housing 21, and is encapsulated inside the motor housing 21 by the guide inner cylinder 23.

[0027] The motor spindle 11 is equipped with an inner guide ring 16, whose outer diameter matches the inner diameter of the guide inner cylinder 23. A corresponding outer guide ring 25, whose inner diameter matches the outer diameter of the motor spindle 11, is installed on the inside of the motor housing 21. The inner guide ring 16 is located on the bottom side of the motor spindle 11, while the outer guide ring 25 is located on the top inner side of the motor housing 21. The outer diameter of the inner guide ring 16 is larger than the outer diameter of the guide sleeve 14, while the inner diameter of the outer guide ring 25 is smaller than the inner diameter of the guide inner cylinder 23. Preferably, a gap of 0.1mm-1mm is maintained between the outer diameter of the guide sleeve 14 and the inner diameter of the guide inner cylinder 23. When the motor mover 10 moves to the maximum distance position, the outer guide ring 25 blocks the movement of the inner guide ring 16, ensuring that the motor stator does not disengage. A buffer pad 17 is provided at the bottom end of the motor spindle 11. When the motor mover 10 moves to the minimum distance position, the buffer pad 17 provides a buffer between the bottom end of the motor stator 20 and the motor stator 20.

[0028] The inner guide ring 16 of the present invention is located within the guide inner cylinder 23. The guide inner cylinder 23 provides positional guidance for the inner guide ring 16, causing the inner guide ring 16 to reciprocate linearly along the inner wall of the guide inner cylinder 23. The guide sleeve 14 of the present invention is located within the outer guide ring 25. The outer guide ring 25 provides positional guidance for the guide sleeve 14, causing the guide sleeve 14 to reciprocate linearly along the inner wall of the outer guide ring 25. The present invention utilizes the inner guide cylinder 23, the guide sleeve 14, the inner guide ring 16, and the outer guide ring 25 to form a guide structure, achieving the guiding function. The guide structure is designed to be located between the motor's moving stator, resulting in a thin and compact structure.

[0029] As an embodiment, a water system is provided within the motor spindle 11. The water system comprises multiple S-shaped water channels arranged radially within the motor spindle 11. Specifically, the first and last ends of the S-shaped water channels are located at the top and bottom of the motor spindle 11, respectively. The multiple S-shaped water channels within the motor spindle 11 are connected end to end to form the water system. The water outlet 2 and water inlet 1 of the water system are located on the same side of the top of the motor spindle 11. The design of the water system in this utility model makes the motor structure more compact while improving heat dissipation efficiency.

[0030] As an embodiment, the motor spindle 11 is equipped with an encoder 15 that detects displacement by reading the motor magnet 22. The encoder 15 is located at the bottom of the motor spindle 11. This design eliminates the need for a separate scale attached to the motor, and this feedback method allows the motor to be used in harsh environments. The encoder cable 18 and motor power cable 19 pass through the motor spindle 11. The encoder 15 is connected to the host computer via the encoder cable 18, and the coil is connected to the motor drive circuit via the motor power cable 19.

[0031] As an embodiment, an annular dust cover 24 is provided at the top of the motor housing 21, and a dust groove 26 is recessed on the inner wall of the dust cover 24. The dust cover 24 of the present invention can prevent external dust from entering the guide inner cylinder 23.

[0032] As an embodiment, the motor stator 20 is provided with an air passage connecting the outside and the guide inner cylinder 23. The air passage ensures that the air pressure inside and outside the motor stator 20 is balanced when the motor mover 10 moves.

[0033] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
