As shown in fig. 1 to 5, the invention provides a clutch device of a transmission mechanism for intelligent furniture, which comprises a fixed shaft 1, a clutch hanging table 2, a limiting ring 3, a magnet roller 4, a corner sleeve 5, a driving gear 6 and a driven gear 7, wherein the clutch hanging table 2 is sleeved on the fixed shaft 1, a central shaft 61 of the driving gear 6 is sleeved on the clutch hanging table 2, the corner sleeve 5 is sleeved on the central shaft 61 of the driving gear 6, the limiting ring 3 is sleeved outside the corner sleeve 5, the magnet roller 4 is adsorbed on the clutch hanging table 2, the driven gear 7 is covered on the clutch hanging table 2, and the magnet roller 4 is positioned between the corner sleeve 5 and the driven gear 7 and adsorbed on the clutch hanging table 2 and the corner sleeve 5. Wherein, the clutch hanging table 2 is fixedly connected with the fixed shaft 1, and the angle sleeve 5 is fixedly connected with the driving gear 6.

The clutch hanging table 2 comprises a platform part 21 and a protruding part 22 extending downwards from the platform part 21, a mounting hole 23 is formed in the protruding part 22, and the magnet roller 4 is adsorbed on the platform part 21. In this embodiment, the shapes of the fixed shaft 1, the central shaft 61 of the driving gear 6, the corner sleeve 5 and the mounting hole 23 are regular polygons, and the fixed shaft 1 is inserted into the mounting hole 23, so that the fixed shaft 1 and the mounting hole 23 can be fixedly connected, and the central shaft 61 of the driving gear 6 and the corner sleeve 5 can also be fixedly connected. The number of the magnet rollers 4 is the number of sides of a polygon, the platform part 21 is circular, and the magnet rollers 4 are uniformly distributed in the circumferential direction of the platform part 21.

The limiting ring 3 comprises a ring body 31 and a plurality of convex parts 32 extending upwards from the ring body 31, and a hollow part capable of accommodating the magnet roller 4 is formed between the adjacent convex parts 32. In this embodiment, the number of the protruding portions 32 is the number of the polygonal sides, the protruding portions 32 are used for limiting, when the driving gear 6 drives the corner sleeve 5 to rotate, since the clutch hanging table 2 is fixed, the magnet rollers 4 are attracted to the platform portion 21 and the corner sleeve 5 due to magnetic force, and since the corner sleeve 5 is polygonal, when the corner sleeve 5 rotates, the magnet rollers 4 are ejected outwards due to the transition of the sides of the corner sleeve 5 to the corners, at this time, due to the limiting effect of the protruding portions 32, the magnet rollers 4 cannot move towards the left and right sides, and the top and the bottom of the magnet rollers are managed by the platform portion 21 and the ring body 31, so that the magnet rollers can be ejected outwards only, and therefore the magnet rollers can be smoothly ejected into the driven gear 7, and further drive the driven gear 7 to rotate. When a certain driving gear 6 rotates for a certain angle in the opposite direction, the magnet roller 4 is brought back by the angle sleeve 5 due to magnetic force to return and disengage from the driven gear 7, and in addition, when an external device is tapped at the time of sudden power failure, the magnet roller 4 can also return and disengage from the driven gear 7.

The magnet roller 4 includes a steel sleeve 41 and a magnet 42 disposed inside the steel sleeve 41. The steel sleeve 41 protects the magnet 42 and prevents the magnet 42 having a high brittleness from being broken.

The angle sleeve 5 and the clutch hanging table 2 are made of iron-containing materials, so that the magnetic attraction effect can be generated between the angle sleeve and the magnet roller 4. The limiting ring 3 and the driven gear 7 are made of non-magnetic materials.

The outer side surface of the central shaft of the driving gear 6 is formed with snap teeth 62 for snapping the corner sleeve 5, so as to realize the stable connection of the driving gear 6 and the corner sleeve 5.

The driven gear 7 includes a cover 71 and a gear portion 72 extending upward from the cover 71, wherein the cover 71 is adapted to cover the clutch mount 2, and the like, and when assembled, a side wall of the cover 71 is located between the clutch mount 2 and a side wall of the driving gear 6.

The clutch hanging table comprises a fixed shaft 1, a clutch hanging table 2, a limiting ring 3, a magnet roller 4, a corner sleeve 5, a driving gear 6 and a driven gear 7, wherein when the driving gear 6 rotates, the corner sleeve 5 rotates along with the driving gear, the magnet roller 4 is pushed outwards and is supported against the inner wall of the driven gear 7, and therefore the driven gear 7 is driven to rotate; when the driving gear 6 rotates reversely, the magnet roller 4 returns, the driven gear 7 does not rotate along with the driving gear 6 any more, and the magnet roller 4 can return as long as the cabinet door is tapped, so that the cabinet door can be opened and closed manually, and the automatic and manual free switching of the cabinet door can be realized.

Appropriate changes and modifications to the embodiments described above will become apparent to those skilled in the art from the disclosure and teachings of the foregoing description. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention are also intended to fall within the scope of the appended claims.
