[0020] It should be noted that, unless there is a conflict, the embodiments in this application and the features described in the embodiments can be combined with each other. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] In the embodiments of the present invention, if there are directional indications (such as up, down, left, right, front, back, etc.), they are only used to explain the relative position relationship and movement status of the various components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] In addition, in this utility model, the terms "first," "second," etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of these features.

[0023] Please refer to Figures 1 to 4 The rod-shaped motor of the embodiment of the present invention includes a mover mechanism 10 and a stator mechanism 20 .

[0024] The stator mechanism 20 is provided with a stator guide sleeve 21 and a stator guide ring 22, while the mover mechanism 10 is provided with a mover guide sleeve 11 and a mover guide ring 12. The stator guide ring 22 corresponds to the mover guide sleeve 11, and the stator guide sleeve 21 corresponds to the mover guide ring 12. The mover guide ring 12 is located within the stator guide sleeve 21. The stator guide sleeve 21 causes the mover guide ring 12 to move axially along the inner wall of the stator guide sleeve 21. The stator guide ring 22 is sleeved outside the mover guide sleeve 11, causing the mover guide sleeve 11 to move axially along the stator guide ring 22. This allows the mover mechanism 10 and the stator mechanism 20 to be guided by the stator guide ring 22 and the mover guide sleeve 11, and the stator guide sleeve 21 and the mover guide ring 12. Preferably, the stator guide sleeve 21 and the mover guide sleeve 11 are both cylindrical or tubular. The present utility model has a simple and compact structure.

[0025] In one embodiment, the mover mechanism 10 is mounted in the stator guide sleeve 21. Specifically, the stator guide sleeve 21 adopts an inner cylinder structure (or inner tube structure) and is located within the stator mechanism 20; the mover guide sleeve 11 adopts an outer cylinder structure and is mounted outside the mover mechanism 10. In a specific implementation, the stator guide sleeve 21 can also adopt an outer cylinder structure and be mounted outside the stator mechanism 20, while the mover guide sleeve 11 adopts an inner cylinder structure and is mounted inside the mover mechanism 10. That is, the mover guide sleeve 11 of the mover mechanism 10 is mounted outside the stator mechanism 20. Preferably, the outer diameter of the mover guide sleeve 11 is smaller than the outer diameter of the mover guide ring 12.

[0026] As an embodiment, the outer diameter of the mover guide ring 12 matches the inner diameter of the stator guide sleeve 21 (i.e., the outer diameter of the mover guide ring 12 is less than or equal to the inner diameter of the stator guide sleeve 21), and the outer diameter of the mover guide sleeve 11 matches the inner diameter of the stator guide ring 22 (i.e., the outer diameter of the mover guide sleeve 11 is less than or equal to the inner diameter of the stator guide ring 22). Preferably, the outer diameter of the mover guide ring 12 is equal to the inner diameter of the stator guide sleeve 21, and the outer diameter of the mover guide sleeve 11 is equal to the inner diameter of the stator guide ring 22. The outer diameter of the mover guide ring 12 is larger than the outer diameter of the mover guide sleeve 11, and the inner diameter of the stator guide sleeve 21 is larger than the inner diameter of the stator guide ring 22. In specific implementations, the outer diameter may be slightly larger, so that the gap between the mover mechanism 10 and the stator mechanism 20 is very small (the gap can be less than 0.5 mm), thereby making the overall structure very thin.

[0027] As an embodiment, the stator guide ring 22 is located at the top of the stator guide sleeve 21, and the mover guide ring 12 is located at the bottom of the mover guide sleeve 11, so that when the mover mechanism 10 moves, the upper and lower ends are guided and limited by the action of the stator guide ring 22 on the mover guide sleeve 11 and the action of the stator guide sleeve 21 on the mover guide ring 12, respectively, thereby improving the stability of the movement of the mover mechanism 10.

[0028] As an embodiment, the inner diameter of the stator guide ring 22 is smaller than the outer diameter of the mover guide ring 12 , thereby preventing the mover mechanism 10 from falling out of the stator guide sleeve 21 .

[0029] In one embodiment, an encoder 23 is provided on the exterior or end of the stator mechanism 20. Encoder 23 is a magnetic grating encoder 23. The mover mechanism 10 is provided with a plurality of magnets 13, with the magnetic poles of the magnets 13 arranged in an alternating pattern (N, S, N, S, etc.). The encoder 23 detects the operating position of the rod motor by reading and identifying the magnets 13 on the mover mechanism 10. This utility model eliminates the need for a separate scale attached to the motor, and its feedback method can be used in harsh environments. This utility model can overcome various complex environments and ensure the normal operation of the motor.

[0030] As an embodiment, a buffer pad 14 is provided at the end of the mover mechanism 10 (ie, the end facing the stator mechanism 20). The buffer pad 14 is used to provide buffering and shock absorption when the mover mechanism 10 moves toward the stator mechanism 20 to the end of the operating stroke.

[0031] 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.
