[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a clutch type motor rotor structure.

[0026] The utility model provides Figure 1-3 A clutch motor rotor structure shown includes a housing 1 and a stator 2 arranged on the inner wall of the housing 1, a main shaft 3 is rotatably provided at the end of the housing 1, a rotor 4 is sleeved on the outer side of the main shaft 3, an end cover 5 is provided at the end of the housing 1, a mounting bolt 20 is threadedly passed through the end cover 5 and the housing 1, a drive shaft 6 is rotatably provided at the side of the end cover 5, a connecting plate 7 is fixedly provided at one end of the drive shaft 6, a friction plate 8 is provided inside the connecting plate 7 through an elastic sliding mechanism, an extrusion plate 9 is fixedly provided at the end of the main shaft 3, and the friction plate 8 and the extrusion plate 9 are arranged in cooperation;

[0027] A cylinder 10 is fixedly provided on the side wall of the end cover 5, and the end of the piston rod of the cylinder 10 passes through the end cover 5 and is fixedly provided with a plurality of push rods 11. A ball 21 is rollingly embedded on one end of the plurality of push rods 11 close to the friction plate 8, and a synchronous ring 12 is fixedly sleeved on the outer sides of the plurality of push rods 11. The push rods 11 are matched with the friction plate 8, and the elastic sliding mechanism includes a plurality of slide rods 13. The plurality of slide rods 13 are slidably penetrated through the interior of the connecting plate 7 and inserted into the friction plate 8. A plurality of slots for mating with the slide rods 13 are provided on the surface of the friction plate 8, and a quick release mechanism is provided between the slide rods 13 and the slots. A first spring 14 is provided on the rod wall sleeve of the slide rod 13, and the two ends of the first spring 14 are fixedly connected to the slide rod 13 and the connecting plate 7 respectively.

[0028] During the operation of the motor, the oil cylinder 10 starts and pushes the multiple push rods 11 through the synchronous ring 12, so that the multiple push rods 11 push the friction plate 8. At this time, the friction plate 8 is close to the extrusion plate 9 under the connection of the multiple slide bars 13 and the first spring 14 and finally squeezes and contacts with the extrusion plate 9. At this time, under the action of extrusion friction, when the rotor 4 drives the main shaft 3 to rotate, the synchronous rotation of the extrusion plate 9 and the friction plate 8 can make the drive shaft 6 rotate quickly. When the drive shaft 6 needs to be stopped quickly in a power-off environment, the oil in the oil cylinder 10 shrinks. At this time, the multiple first springs 14 are not squeezed and drive the friction plate 8 away from the extrusion plate 9 through the slide bar 13. At this time, the main shaft 3 is separated from the drive shaft 6, and the drive shaft 6 can be stopped quickly.

[0029] In order to facilitate the removal and replacement of the friction plate 8 after the friction plate 8 has been used for a long time, Figure 2-3 As shown, the quick release mechanism includes a card block 15, a card slot is opened on the inner side wall of the slot, a movable slot is opened on the tube wall of the slide rod 13, the card block 15 is slidably arranged in the movable slot, and a movable plate 16 is fixedly arranged at the bottom, two second springs 17 are fixedly arranged between the movable plate 16 and the inner wall of the movable slot, guide slots are opened on both sides of the inner wall of the movable slot, guide plates 19 are fixedly arranged on both sides of the movable plate 16, the guide plate 19 is slidably arranged in the guide slot, the card block 15 is inserted into the card slot, and a push block 18 is fixedly arranged on the surface of the movable plate 16, and the push block 18 passes through the movable slot and extends to the outside.

[0030] When the friction plate 8 needs to be replaced, the mounting bolts 20 are unscrewed to separate the end cover 5 and the casing 1, exposing the friction plate 8, and then the multiple push blocks 18 are pressed so that the push blocks 18 drive the movable plate 16 and the card block 15 to be pulled out from the inside of the card slot, and the second spring 17 is squeezed. At this time, the friction plate 8 can separate the multiple slide bars 13 and complete the disassembly. When installing the friction plate 8, the friction plate 8 is directly moved close to the slide bar 13. Through the inclined surface of the card block 15, the card block 15 can be squeezed and quickly stuck into the card slot, thereby completing the installation of the friction plate 8, so that the friction plate 8 can be stably extruded and connected inside the motor, thereby improving the stability of the motor during operation.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
