In the exemplary embodiment, the first motor 12, the second motor 21, and the third motor 31 all adopt a control structure of interlocking of forward and reverse rotation, so as to avoid power supply short circuit and electrical appliance failure caused by misoperation.
Indeed, the above description is based on a complete control process of both the front and rear covers opening/closing; there are cases where only the front cover or the rear cover needs to be opened/closed alone during actual use.
In one embodiment, if the front cover or the rear cover needs to be opened separately, the controller operation interface provides the user with the selection of the opening operation to be performed. Specifically, the user selects to open only the front cover, the automatic opening control of the front cover is the same as the opening process of the front cover, after the front cover is opened in place, the control program locks the equipment state to keep the equipment state in the state of opening only the front cover, and after the equipment is repaired or maintained, the equipment is started to execute the closing operation of the front cover through the control of a key switch. The opening of the separate rear cover is similar to this and will not be described further here.
In another embodiment, the key switch comprises a first key switch for controlling the front cover to be opened and a second key switch for controlling the rear cover to be opened. When the front cover needs to be opened, the first key switch is closed, and then the control device of the front cover is triggered to execute the opening operation of the front cover; when the front cover needs to be closed, the first key switch is switched off, and then the control device of the front cover is triggered to execute the front cover closing operation. Similarly, the opening/closing of the rear cover triggers the control device of the rear cover to execute corresponding opening/closing operation through the on-off of the second key switch. For convenience of description, the control device described herein is a general term for the actuator in the housing opening/closing operation described in the exemplary embodiment of the present application.
In another embodiment, the key switch is set as a contact switch, when a key is inserted into the key switch and is rotated to a specified position at the left, the control circuit for opening and closing the front cover is conducted, and the system executes the opening/closing operation of the front cover; when the key is inserted into the key switch and rotates rightwards to a designated position, the control circuit for opening and closing the rear cover is conducted, and the system executes the opening/closing operation of the rear cover. Of course, the left-handed control of the front cover opening and the right-handed control of the rear cover opening after the key is inserted are only described as examples and do not limit the embodiments of the present application.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
