Referring to fig. 4, the magnetic element 600 is indirectly connected to the driving unit 200 and can rotate synchronously with the rotating shaft 400 when the driving unit 200 drives the rotating shaft 400 to rotate. The induction circuit board 30 is close to the proximal side of the case 10 and fixed relative to the case 10 to induce a change in its magnetic field during rotation of the magnetic member 600. In the present embodiment, the sensing circuit board 30 is located on the outer side surface of the casing 10, and the magnetic member 600 is axially spaced from the sensing circuit board 30, so as to prevent the sensing circuit board 30 from being damaged due to the axial movement of the rotating shaft 400. The magnetic member 600 may be a magnet or a magnet.

Referring to fig. 3, the box 10 includes a first housing 11 and a second housing 12, and the first housing 11 and the second housing 12 can be relatively covered or separated. When the first housing 11 and the second housing 12 are covered, a chamber is defined therebetween, and the driving unit 200 is located in the chamber. When the first housing 11 and the second housing 12 are separated, it is possible to facilitate installation or removal of the driving unit 200, the rotation shaft 400, and the like. As shown in fig. 3 and 4, the first housing 11 is provided with a through escape hole 101 in the thickness direction, and the second housing 12 is provided with a through protruding hole 102 in the thickness direction. When the box 10 is in an assembled state, the avoiding hole 101 and the extending hole 102 are both communicated with the chamber defined by the first shell 11 and the second shell 12, and the center line of the avoiding hole 101 and the center line of the extending hole 102 are located on the same straight line. The distal end of the rotation shaft 400 is protruded out of the case 10 through the protrusion hole 102 to be connected to an external component, corresponding to the position where the protrusion hole 102 is provided on the case 10.

Referring to fig. 3, the container 10 further includes a cover 110, and the cover 110 is spaced apart from the rotating assembly 20 by a predetermined distance. Specifically, the cover 110 is connected to the first housing 11. As shown in fig. 4, when the transmission device is in an assembled state, the sealing cover 110 covers the first casing 11 and completely covers the avoiding hole 101 formed in the first casing 11 in the axial direction, so as to further prevent dust and other impurities from entering the inside of the box 10 through the avoiding hole 101.

The sensing circuit board 30 has a sensing element, which can be a hall element or other elements for detecting the change of the magnetic field of the magnetic element 600. When the magnetic member 600 rotates, the magnetic field changes, and the sensing element on the sensing circuit board 30 senses the magnetic field change and performs further processing. The line connecting the center point of the sensing element on the sensing circuit board 30 and the center point of the magnetic member 600 is located on the same line as the center axis of the rotating shaft 400, so as to improve the detection accuracy.

Because the shaft end cover 210 and the sealing cover 110 are spaced at a certain distance in the axial direction, that is, the shaft end cover 210 does not contact the sealing cover 110, the sensing circuit board 30 may be disposed on the inner side surface of the sealing cover 110, or may be disposed on the outer side surface of the sealing cover 110, and is not affected by the shaking of the shaft end cover 210. In this embodiment, the sensing circuit board 30 is disposed on the outer side surface of the cover 110, so that the sensing circuit board 30 is located outside the casing 10, which can prevent the sensing circuit board 30 from being corroded by the water vapor entering from the distal end of the rotating shaft 400 to cause corrosion and aging, and prolong the service life of the sensing circuit board 30.

Referring to fig. 3, a baffle 111 is formed on an outer side surface of the cover 110, and the baffle 111 protrudes from the outer side surface of the cover 110 by a predetermined height. In the present embodiment, the projection of the baffle 111 in the thickness direction of the cover 110 is a closed ring, that is, the baffle 110 defines a receiving area 112. The induction circuit board 30 is at least partially embedded in the accommodating area 112, and the side of the induction circuit board 30 on which the induction element is arranged faces the accommodating area 112.

The magnetic member 600 is positioned within the cylinder 230 and fixed with respect to the cylinder 230. When the sleeve 220 is driven by the gear set to rotate, the sleeve 220, the shaft cover 210 and the rotating shaft 400 rotate synchronously around the same straight line, the magnetic field of the magnetic member 600 located in the shaft cover 210 changes in the rotating process, and the sensing circuit board 30 located on the outer side surface of the cover 110 senses the magnetic field change of the magnetic member 600 to know the rotating angle of the rotating shaft 400.

Referring to fig. 4, the proximal end of the cylinder 230 passes through the avoiding hole 101 and extends out of the housing 10, and the cylinder 230 and the cover 110 are spaced apart from each other by a predetermined distance, so that the shaft cover 210 does not contact the cover 110, the shaft cover 210 is prevented from exerting a force on the cover 110 during the movement, and the sensing circuit board 30 located on the outer side of the cover 110 is prevented from being affected.
