Abstract
The present invention discloses a box cover device extended and retracted in a transmission manner and a control method thereof. The device comprises a transmission gear, a roller shutter shaft gear and a clutch gear. The transmission gear and the roller shutter shaft gear are arranged oppositely, and a clutching space is reserved between the transmission gear and the roller shutter shaft gear. A middle shaft is arranged at the center line of the clutching space vertical to the center connection line of the transmission gear and the roller shutter shaft gear. The box cover device extended and retracted in a clutch type transmission manner of the present invention is convenient and quick to operate and has high working efficiency
Claims11
A box cover device extended and retracted in a transmission manner, comprising a gearbox, a transmission motor, a roller shutter cover and a transmission controller, wherein
- the gearbox comprises a transmission gear, a roller shutter shaft gear and a clutch gear;
- the transmission gear and the roller shutter shaft gear are arranged oppositely, and a clutching space is reserved between the transmission gear and the roller shutter shaft gear;
- a middle shaft is arranged at the center line of the clutching space vertical to the center connection line of the transmission gear and the roller shutter shaft gear;
- the clutch gear sleeves the middle shaft and is engaged with the transmission gear and the roller shutter shaft gear;
- a translation mechanism is arranged between the middle shaft and a gearbox case wall;
- the translation mechanism controls the middle shaft to drive the clutch gear to move close to/away from the transmission gear and the roller shutter shaft gear;
- the clutch gear, the transmission gear and the roller shutter shaft gear form a gear clutch;
- the transmission gear is connected with an output shaft of the transmission motor;
- the output shaft drives the transmission gear to rotate in a forward/reverse manner or stop;
- the roller shutter shaft gear is connected with a roller shutter shaft and drives the roller shutter shaft to rotate in a forward/reverse manner or stop so as to drive a roller shutter cover connected with the roller shutter shaft to extend/retract or stop;
- the roller shutter cover is located at an opened top of a box;
- the roller shutter cover gradually covers the box during extension and uncovers the box during retraction;
- the clutch gear connects/disconnects engagement transmission with the transmission gear and the roller shutter shaft gear when moving close to/away from the transmission gear and the roller shutter shaft gear;
- the transmission controller is connected with the transmission motor;
- the transmission controller receives forward/reverse rotation or stop control signals, then generates relative control commands to control the transmission motor to rotate in a forward/reverse manner or stop.
A control method of the box cover device extended and retracted in a transmission manner, comprising:
- oppositely arranging the transmission gear and the roller shutter shaft gear and reserving a clutching space between the transmission gear and the roller shutter shaft gear;
- arranging a middle shaft at the center line of the clutching space vertical to the center connection line of the transmission gear and the roller shutter shaft gear;
- using the clutch gear to sleeve the middle shaft such that the clutch gear is engaged with the transmission gear and the roller shutter shaft gear;
- arranging a translation mechanism between the middle shaft and the gearbox case wall;
- connecting the transmission gear and the output shaft of the transmission motor;
- connecting the roller shutter shaft gear and the roller shutter shaft;
- connecting the roller shutter shaft and the roller shutter cover;
- placing the roller shutter cover at the opened top of the box;
- connecting the transmission controller and the transmission motor to form a box cover extended and retracted in a transmission manner;
- when the transmission controller receives the extension, retraction or stop control signal for the roller shutter cover, relatively generating the forward/reverse rotation or stop control signal to control the transmission motor to rotate in a forward/reverse manner or stop, driving the roller shutter shaft gear to rotate in a forward/reverse manner or stop through engagement transmission, so as to drive the roller shutter cover to extend, retract or stop;
- using the translation mechanism to control the middle shaft to drive the clutch gear to move away from the transmission gear and the roller shutter shaft gear, so as to release engagement with the transmission gear and the roller shutter shaft gear, wherein the roller shutter shaft gear separates from the engagement transmission with the transmission gear;
- using the translation mechanism to control the middle shaft to drive the clutch gear to move close to the transmission gear and the roller shutter shaft gear, so as to recover engagement with the transmission gear and the roller shutter shaft gear, wherein the roller shutter shaft gear recovers engagement transmission with the transmission gear.
