Abstract
The utility model discloses a desktop flatness control device for an electric lifting desk, which comprises mains supply, wherein the mains supply is connected with an MCU (Microprogrammed Control Unit) and a power module respectively; a switch power supply is arranged at the input end of the MCU; a relay is arranged at the input end of the power module; the output end of the power module is connected with an angle sensor module and a motor main control unit respectively; the angle sensor module is connected with the MCU; and the MCU is connected with the relay and used for controlling the relay. By the desktop flatness control device for the electric lifting desk, a system can be protected immediately when a desktop is inclined, the desktop flatness is detected by the angle sensor module in real time, the angle sensor module can output a desktop out-of-flatness signal to the MCU once the desktop is inclined, and the MCU sends out a control signal after receiving the desktop out-of-flatness signal so as to enable the relay to act continuously, so that a power supply of the motor main control unit is cut off and the desktop is in the flat state all the time.
Description
Technical field
The utility model relates to a kind of desktop flatness control device of electric elevatable table.
Background technology
Traditional lift control system, general by gathering the feedback signal of d.c. motor, and convert feedback signal to the electric pushrod stroke by certain algorithm, thus the synchronous operation of many electric pushrods controlled, when the electric pushrod of lift control system, during the situations such as the appearance worm gear skids, slide nut tooth, the feedback signal of d.c. motor output is normal, but running part goes wrong, and desk will not controlled run-off the straight, cause damage, there is certain defect in this control mode.
The utility model content
The purpose of this utility model is to provide the desktop flatness control device of electric elevatable table.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The desktop flatness control device of electric elevatable table, comprise civil power, civil power connects respectively MCU control module and power module, the input end of MCU control module is provided with Switching Power Supply, it is characterized in that: the input end of power module is provided with relay, the output terminal of power module is connection angle sensor assembly and motor main control unit respectively, and the angular transducer module connects the MCU control module, and the MCU control module connects and pilot relay.
The utility model is owing to having adopted technique scheme; can guarantee when desktop occurs tilting; system enters protection at once; detect in real time the flatness of desktop by the angular transducer module; in case find the desktop run-off the straight; the angular transducer module will be exported desktop out-of-flatness signal to the MCU control module; the MCU control module is after receiving this signal; send control signal and make the relay effect; thereby cut off the power supply of motor main control unit; lift control system is maintained the original state, be unlikely to desk and further draw badly, cause unnecessary secondary to damage.The utility model is simple in structure, and reliable operation is practical.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the theory diagram of the desktop flatness control device of the utility model electric elevatable table.
Embodiment
As shown in Figure 1, desktop flatness control device for the utility model electric elevatable table, comprise civil power, civil power connects respectively MCU control module and power module, the input end of MCU control module is provided with Switching Power Supply, and the input end of power module is provided with relay, and the output terminal of power module is connection angle sensor assembly and motor main control unit respectively, the angular transducer module connects the MCU control module, and the MCU control module connects and pilot relay.Detect in real time the flatness of desktop by the angular transducer module, in case find the desktop run-off the straight, the angular transducer module will be exported desktop out-of-flatness signal to the MCU control module, the MCU control module is after receiving this signal, send control signal and make the relay effect, thereby the power supply of cut-out motor main control unit maintains the original state lift control system, be unlikely to desk and further draw badly, cause unnecessary secondary to damage.
