[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0023] Reference Figures 1 to 5 As shown, an insulated tubular motor of the present embodiment includes an outer tube 1, wherein the material of the outer tube 1 is metal, and a motor assembly 2, a reducer 3 and a shell 4 are arranged in the outer tube 1. The reducer 3 is a planetary gear reduction group, and the material of the shell 4 can be plastic. A accommodating space is formed in the shell 4, wherein components such as a circuit board and a power board can be installed in the accommodating space, and the motor assembly 2 is located between the reducer 3 and the shell 4. The motor assembly 2 includes a tubular body 21, and an insulating tube 5 is arranged between the tubular body 21 and the outer tube 1. The arrangement of the insulating tube 5 insulates the tubular body 21 in the motor assembly 2 from the outer tube 1, and can prevent the outer tube 1 from being charged when the motor assembly 2 leaks electricity, thereby improving safety. One end of the insulating tube 5 is connected to the shell 4 and / or the other end of the insulating tube 5 is connected to the reducer 3. The insulating tube 5 is positioned and installed to prevent the insulating tube 5 from loosening and increase the firmness of the insulating tube 5.

[0024] Preferably, one end of the insulating tube 5 is clamped to the shell 4, and the other end of the insulating tube 5 is abutted against the reducer 3; of course, the other end of the insulating tube 5 can also be clamped to the reducer 3; the method of clamping only one end is more convenient for installation.

[0025] Reference Figure 3 As shown, a first step 41 is formed on one end of the housing 4 facing the motor assembly 2. One end of the insulating tube 5 and / or one end of the tube body 21 abut against the first step 41. The first step 41 can support one end of the insulating tube 5 and locate its installation position.

[0026] A specific implementation scheme may be as follows: one end of the insulating tube 5 is longer than the end of the tube body 21 on the same side, so that the insulating tube 5 abuts against the first step 41, and the tube body 21 does not abut against the first step 41. The tube body 21 may abut against the housing 4 below the first step 41 or at another position.

[0027] Alternatively, the length of one end of the insulating tube 5 may be shorter than the length of the end of the tube body 21 on the same side. In this case, the structure of the housing 4 facing the insulating tube 5 is changed, and the first step 41 extends toward the insulating tube 5, so that insulation between the tube body 21 and the outer tube 1 is achieved through the housing 4.

[0028] The material of the housing 4 may also be plastic;

[0029] Preferably, one end of the insulating tube 5 and one end of the tube body 21 are both against the first step 41 ; this simplifies installation and increases the installation stability of the tube body 21 .

[0030] Reference Figure 3 As shown, a plurality of clamping members 42 are formed at the first step 41, wherein the clamping members 42 are integrally formed with the housing 4. In this embodiment, there are two clamping members 42, which are symmetrically arranged. A clamping groove 51 adapted to the clamping member 42 is formed at one end of the insulating tube 5 and / or one end of the tube body 21.

[0031] Preferably, one end of the insulating tube 5 and one end of the tube body 21 are both provided with a card slot 51 adapted to the card member 42;

[0032] The thickness of the clamp 42 is equal to the sum of the thicknesses of the insulating tube 5 and the tube body 21 ; when the clamping groove 51 is engaged with the clamp 42 , the tube body 21 will not protrude from the first step 41 , so that the tube body 21 will not interfere with the installation of the outer tube 1 .

[0033] Reference Figure 3 、 Figure 5 As shown, a plurality of countersunk holes 211 are provided at one end of the tube body 21 facing the shell 4, wherein the number of the countersunk holes 211 is two, and correspondingly, the number of the threaded holes 43 is also two, and the countersunk holes 211 are located between the two clamps 42, that is, the countersunk holes 211 and the clamps 42 are spaced apart, and a threaded hole 43 corresponding to the countersunk hole 211 is provided at one end of the shell 4 facing the tube body 21, and the shell 4 and the tube body 21 are connected by screws to increase the connection firmness between the shell 4 and the tube body 21.

[0034] Reference Figure 2 As shown, a second step 31 is formed on one end of the reducer 3 facing the motor assembly 2, and the other end of the insulating tube 5 and / or the other end of the tube body 21 abuts against the second step 31, and the second step 31 is opposite to the first step 41;

[0035] Preferably, the other end of the insulating tube 5 and the other end of the tube body 21 are both against the second step 31, and the second step 31 plays a role in supporting the tube body 21 and the insulating tube 5, and also locates the installation position of the tube body 21 and the insulating tube 5;

[0036] The second step 31 cooperates with the first step 41 to limit the movement of the insulating tube 5 and the tube body 21 along the central axis thereof.

[0037] A stroke detection mechanism is provided between the motor assembly 2 and the housing 4 , and detection is performed through the stroke detection mechanism.

[0038] Reference Figure 6As shown, the stroke detection mechanism includes a Hall plate 61, on which two Hall sensors 62 are provided. A magnetic ring is fixedly connected to the output end of the motor assembly 2 facing the Hall plate 61. The motor assembly 2 includes two output ends, one of which is connected to the reducer 3, and the other is connected to the magnetic ring. The magnetic ring has a plurality of N poles and S poles circumferentially arranged along its central axis, wherein the N poles and S poles are arranged at intervals.

[0039] When the output end rotates, the rotation distance and rotation direction of the output end can be detected through the induction of the Hall sensor 62, thereby detecting the stroke.

[0040] The insulating tube 5 is made of plastic, which reduces the overall weight and also reduces the cost.

[0041] The above are only preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
