Description
Technical field
The present invention relates to desk field more particularly to a kind of electric up-down desks.
Background technique
Currently, the desk that student uses mostly is unable to adjust height, thus the student for being difficult to adapt to different heights uses, and makes
Incorrect at sitting posture of student, reading and writing tires out uncomfortable, seriously affects student's corporally normal development.Part can as shown in Figure 1
The desk of hand adjustment height, when it is hand to suitable height when, no longer adjust height, substantially used with common student
Desk difference is little.
Summary of the invention
To solve existing technical problem, the present invention provides a kind of electric up-down desks can be right by Electronic control
Student plays the role of adjusting desk height in study and reminds student.
Particular content of the present invention is as follows: a kind of electric up-down desk, including desk ontology, crossbeam, electric machine support, motor are total
At, buzzer, cradle, reset switch, lift adjustment switch and power switch；The desk ontology is equipped with control desk desktop
The elevating mechanism of lifting, elevating mechanism are connected with crossbeam, and the electric machine support and motor assembly are arranged on crossbeam, motor assembly
Elevating mechanism movement is controlled, the buzzer, cradle, reset switch, lift adjustment switch and power switch are total with motor
At electrical connection.
Further, the crossbeam includes left crossbeam and right crossbeam, is equipped with left drive shaft and left coupling, institute in left crossbeam
It states and is equipped with right screw mandrel, battery and right transmission shaft in the right crossbeam, and the battery is fixed on the right crossbeam；Institute
The output shaft for stating motor assembly passes through left coupling, right screw mandrel and left drive shaft respectively, right transmission shaft is connected；The left biography
Moving axis, right transmission shaft are connected with the elevating mechanism of desk ontology respectively
Further, the battery, the power switch and the motor assembly are connected in series；It is the buzzer, described
Setting switch, lift adjustment switch are connected with the motor assembly respectively；The cradle and the battery are in parallel, and
There is a negative line to be connected with the motor assembly.
Further, the motor assembly includes motor body and control panel, when electric up-down desk is arranged and runs, institute
It states motor body and is inverted to stall position, the control panel motor body Hall umber of pulse will reset at this time and mark this position to be
Zero-bit；Control panel controls motor body again and is just going to stall position, the Hall umber of pulse of record motor body operating at this time, and marks
Remember that this position is 100%.
Further, when electric up-down desk works, power switch closure, lift adjustment is closed the switch, the motor sheet
Body drives elevating mechanism operation；The motor assembly records the Hall umber of pulse of this operation, former if motor body rotates forward
