Detailed Description

The invention is described in further detail below with reference to the accompanying drawings:

referring to fig. 1-3, the invention relates to an intelligent mobile furniture platform manual-automatic integrated clutch, which comprises a hand wheel 1, a sleeve 2, an adjusting screw rod 3, a movable rod 4, a bearing 5, a snap spring 6, a gasket 7, a screw 8, a clutch shaft 9, a driving sprocket 10 and a driving motor 11, wherein a first guide flat key 12 is arranged at the left end of the movable rod 4, and the movable rod 4 is connected with the sleeve 2 through the first guide flat key 12; the right end of the movable rod 4 is arranged in the clutch shaft 9 through the bearing 5, the movable rod 4 on the inner side of the bearing is also sleeved with the clamp spring 6 for preventing the bearing 5 from falling off, and the clamp spring 6 is clamped in a clamp spring groove 13 on the inner wall of the clutch shaft; the movable rod can be arranged to comprise a large-diameter part, a middle-diameter part and a small-diameter part which are sequentially connected, a first guide flat key is arranged on the large-diameter part, a clamp spring is sleeved outside the middle-diameter part, a bearing is sleeved outside the small-diameter part, the adjusting screw rod 3 is arranged in the movable rod 4 in a penetrating mode and in threaded connection with the adjusting screw rod 3, one end of the adjusting screw rod 3 is in threaded connection with the hand wheel 1, a threaded hole 14 is formed in the other end of the adjusting screw rod 3, and the screw 8 penetrates through the gasket 7 to be in threaded connection with the threaded hole; a second guide flat key 15 is arranged on a motor shaft of the driving motor 11, the motor shaft of the driving motor penetrates through the driving chain wheel 10 to be connected with the clutch shaft 9 through the second guide flat key 16, and two bosses 17 matched with the grooves 16 on the driving chain wheel are arranged on the end face, close to the driving chain wheel 10, of the clutch shaft 9.

Referring to fig. 4, when the movable furniture platform is installed, the movable furniture platform is firstly installed on a fixed support which is fixed on a longitudinal beam of the movable furniture platform, the fixed support comprises two transverse plates and two vertical plates, a sleeve is fixedly arranged in one vertical plate in a penetrating way, the other vertical plate is fixed on the longitudinal beam, and a motor shaft of a driving motor sequentially penetrates through the longitudinal beam, the vertical plates and a driving chain wheel to be matched with a clutch shaft.

Referring to fig. 5, when the present invention is in an automatic mode, i.e. an intelligent control electric mode, a control system 18 on the movable furniture platform controls a driving motor 11, the boss 17 of the clutch shaft 9 engages with the groove 16 of the driving sprocket 10, and the driving motor operates according to a command, and the driving sprocket 10 is transmitted to a driven sprocket 20 on the movable furniture platform through a chain 19 to drive the driven sprocket 20 to rotate, so that the movable furniture platform moves according to the command of the control system.

When the manual mode is used, please refer to fig. 6, that is, when a power failure or a fault occurs and manual operation is required, the hand wheel 1 is only required to be rotated, the hand wheel 1 drives the movable rod 4 to make horizontal linear motion leftward in the sleeve 2 through the adjusting screw rod 3, and further drives the clutch shaft 9 to make horizontal linear motion leftward, and the clutch shaft 9 and a motor shaft of the driving motor 11 are connected through the second guiding flat key 15, so that the clutch shaft 9 keeps directional horizontal movement in the moving process; finally, the boss 17 of the clutch shaft 9 is disengaged from the groove 16 of the driving sprocket 10; when the furniture platform is moved, the driven sprocket 20 drives the driving sprocket 10 to rotate, and the driving sprocket 10 is idle at the moment because the driving sprocket 10 is disengaged from the clutch shaft 9 and is not matched with the driving motor 11 by a key groove, so that the furniture platform is moved manually.

When the incoming call is recovered or the intelligent electric mode is reused after the fault is eliminated, the hand wheel 1 is rotated reversely, the hand wheel 1 drives the movable rod 4 to do horizontal linear motion rightwards in the sleeve 2 through the adjusting screw rod 3, and further drives the clutch shaft 9 to do horizontal linear motion rightwards, and the clutch shaft 9 and the motor shaft of the driving motor 11 are connected through the second guide flat key 15, so that the clutch shaft 9 keeps directional horizontal movement in the moving process; and finally, the boss 17 of the clutch shaft 9 is meshed with the groove 16 of the driving sprocket 10, the driving motor works according to the instruction, and the driving sprocket 10 is transmitted to a driven sprocket 20 on the movable furniture platform through a chain 19 to drive the driven sprocket 20 to rotate, so that the movable furniture platform moves according to the instruction of a control system. Because the clutch shaft 9 is matched with the movable rod 4 by the bearing 5, when the clutch shaft 9 rotates, the outer ring of the bearing 5 actually rotates, and the inner ring of the bearing is installed on the movable rod 4, so that the movable rod 4, the adjusting screw rod 3 and the hand wheel 1 are all static even if the driving motor 11 drives the clutch shaft 9 and the driving chain wheel 10 to rotate.
