Fig. 6 is a schematic flow chart of a control method of the retractable transmission box cover device in this embodiment. At present, the electric roller shutter on the market is only controlled by a 433M remote control key, and if the remote controller is damaged and lost or the remote controller is out of power, the electric roller shutter cannot be used. Meanwhile, since the 433M frequency band belongs to a public frequency band, many other civil devices are used (such as motorcycle keys, automobile keys, electric rolling doors, etc.), and are easily interfered, so that signals are unstable. In this embodiment, the remote control of the housing cover, which is driven to extend and retract, on the housing supports three other control methods in addition to the conventional one.

The first type is especially the control embedded in the original vehicle remote control key on the vehicle box body, and the vehicle key must be carried by a vehicle owner when the vehicle owner uses the vehicle.

Secondly, the small program control, because the popularity of the existing smart phone and the popularity of the social software are very high, based on the social software platform, the small program control of the electric roller shutter is developed, a processor and a Bluetooth module are configured in the transmission controller, the identity information of a user is verified and verified through the data interaction of the small program and a background, and then the Bluetooth module of the box covering device with telescopic transmission is connected, and the box covering device is remotely controlled by receiving control information. The Bluetooth equipment is arranged in the electric roller shutter controller, and a user can control all functions of the electric roller shutter and monitor the state of the electric roller shutter through small program software by using a mobile phone.

And thirdly, the additionally arranged button control is connected to the transmission controller through communication, and the scheme can enable a user to operate the electric roller shutter switch at will under the condition that the user does not leave a control position and needs to open the roller shutter.

Specifically, the control method of the transmission telescopic box body covering device can be implemented by the transmission telescopic box body covering device, and comprises the following steps:

601, arranging a transmission gear and a roller shutter shaft gear oppositely, and reserving a clutch gap in the middle; an intermediate shaft is arranged at the center line of the clutch gap and is vertical to the central connecting line of the transmission gear and the rolling shaft gear; the clutch gear is sleeved on the intermediate shaft and meshed with the transmission gear and the roller shutter shaft gear; a translation mechanism is arranged between the intermediate shaft and the wall of the gearbox shell.

Step 602, connecting the transmission gear with an output shaft of the transmission motor, connecting a roller shutter shaft gear with a roller shutter shaft, connecting a roller shutter cover on the roller shutter shaft, placing the roller shutter cover at the open top cover of the box body, and connecting the transmission controller with the transmission motor to form a transmission telescopic box body cover.

Step 603, when the transmission controller receives the control message of extending, retracting or stopping the roller shutter cover, the transmission controller correspondingly generates a forward rotation, reverse rotation or stop control message to control the transmission motor to rotate forward, reverse or stop, and the transmission controller drives the roller shutter shaft gear to rotate forward, reverse or stop through the meshing transmission belt so as to drive the roller shutter cover to extend, retract or stop.

And step 604, controlling the intermediate shaft to drive the clutch gear to move towards the direction away from the transmission gear and the roller shutter shaft gear through the translation mechanism, releasing the engagement with the transmission gear and the roller shutter shaft gear, and disengaging the roller shutter shaft gear from the engagement transmission of the transmission gear.

Step 605, the intermediate shaft is controlled by the translation mechanism to drive the clutch gear to move towards the direction close to the transmission gear and the rolling shaft gear, the clutch gear is restored to be meshed with the transmission gear and the rolling shaft gear, and the rolling shaft gear is restored to be meshed with the transmission gear for transmission.

The transmission controller placed in the roller shutter box body can detect the received 433MHZ frequency signal, decode the signal, compare the decoded data with the stored remote controller information, if the comparison is successful, the remote controller is considered to be an effective remote control signal, and make corresponding actions (turning on/off the roller shutter and turning on/off the lamp) according to the signal data, if the comparison is failed, the remote controller is considered to be other product signals or interference signals, and does not respond.

Optionally, the transmission telescopic box body covering device further comprises a voltage stabilizer connected between the transmission motor and the power supply, the power supply is controlled to output stable voltage to the transmission motor, the uniform-speed operation of the electric roller shutter is guaranteed, and the problems that the electric roller shutter cannot operate at a uniform speed in the market at present, the roller shutter operates at a high speed under ordinary conditions, and the operation speed of the roller shutter is slowed along with the reduction of the voltage of the battery when the voltage of the power supply is high are solved. The control to the opening and closing position of the electric roller shutter can be set, the control information of the user to the opening and closing position of the electric roller shutter is received, the transmission time for electrifying the driving motor is calculated by combining the total length of the electric roller shutter and the running speed, the power of the driving motor is automatically cut off when the transmission time is reached, and the power is supplied to the driving motor when the control information for recovering the electrification is received. Preferably, the control device can also be used for adjusting the opening and closing speed of the electric roller shutter, receiving a control message of a user on the opening and closing speed of the electric roller shutter, obtaining an adjusted voltage value by combining the operation parameters of the transmission motor and the comparison relation between the voltage of the transmission motor and the operation speed, and controlling the transformer to output the voltage to the transmission motor by adjusting the voltage value.

The motor control part adopts a PID controller mode, and obtains the running speed of the motor in real time through a Hall sensor arranged on a motor shaft; and acquiring the running current of the motor in real time through an on-board IC. The motor driving part is combined with the currently acquired speed and current, and the conduction current of the motor is adjusted in real time in a PWM mode, so that the purpose of uniform running of the roller shutter is achieved. Meanwhile, if the Hall signal is abnormal or the current is abnormal, different sound combinations are sent out through a loudspeaker on the controller to realize abnormal alarm or the electric connection with the transmission motor is cut off in time.

In some alternative embodiments, the translation mechanism is a clutch thread arranged outside the intermediate shaft and cooperating with the wall of the gearbox casing. And (3) screwing a translation push-pull rod and/or a knob and/or a rotary groove at one end of the intermediate shaft, which extends out of the wall of the gear box, and controlling the intermediate shaft to move towards/away from the transmission gear and the roller shutter shaft gear through clutch threads.
