Abstract
The utility model discloses a driver for an electric adjustment device, which comprises a guide rail, a motor, a control circuit, a screw mandrel arranged in the guide rail and a moving bell sleeved on the guide rail. The moving bell is connected with the screw mandrel in a spinning mode; the screw mandrel and the motor are connected through a worm and gear; the motor is connected with a control circuit; and two ends of the guide rail are provided with travel control switches. The utility model has the characteristics of controllable travel and prevention of burning of the electric motor causes by overcurrent, and is suitably applied to products such as an electric bed, an electric chair, an electric lifting table, and the like.
Description
Technical field
The utility model relates to the assembly that a kind of motorized adjustment device is used, particularly a kind of motorized adjustment device driver that is used to regulate lifting on products such as beddo, electrically propelled chair and electric up-down table.
Background technology
The problem that existing motorized adjustment device driver exists is: stroke is not easy control, and motor burns out easily.
Summary of the invention
The purpose of this utility model is to provide a kind of motorized adjustment device driver.
The stroke that is existing motorized adjustment device driver exists to be solved in the utility model is not easy to control the problem that burns out easily with motor.
In order to achieve the above object, the technical scheme that the utility model provides is: it comprises guide rail, motor, control circuit, be located at the screw mandrel in the guide rail, bell alives, the work bell that is placed on the guide rail is rotatably connected on the screw mandrel, be connected by worm and gear between screw mandrel and the motor, motor is connected with control circuit.Two ends at guide rail are provided with travel control switch.
The utlity model has the stroke may command and prevent the advantage that motor burns out because of excess current, very be adapted at using on the products such as beddo, electrically propelled chair and electric up-down table.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, the utility model comprises guide rail (2), motor M (4), is located at screw mandrel (5) and the control circuit in the guide rail (2), bell alive (6), the work bell (6) that is placed on the guide rail (2) is rotatably connected on the screw mandrel (5).Be connected by worm and gear between screw mandrel (5) and the motor M (4).Motor M (4) is connected with control circuit.Two ends at guide rail (2) are provided with travel control switch.Travel control switch comprises descending stroke gauge tap SW1 (3), upward stroke gauge tap SW2 (1), diode D1 and diode D2.Descending stroke gauge tap SW1 (3) is identical with upward stroke gauge tap SW2 (1) structure, and descending stroke gauge tap SW1 is connected with upward stroke gauge tap SW2.Be parallel with diode D1 and diode D2 respectively on descending stroke gauge tap SW1 (3) and the upward stroke gauge tap SW2 (1).Descending stroke gauge tap SW1 (3), upward stroke gauge tap SW2 (1) are connected with motor M (4).
Control circuit comprises relay J 1, relay J 2, triode Q1, triode Q2, triode Q3 and resistance R 3.Triode Q1 is connected with relay J 1, relay J 2, and triode Q3 is connected with triode Q2, triode Q1, resistance R 3.Triode Q1, triode Q2, triode Q3 and resistance R 3 constitute circuit overcurrent protection.
The control of relay J 1 of the present utility model, J2 can be by the hand controller control that is provided with separately.Control circuit of the present utility model also is can be external separately, is located in the independent controller.
Bell alive of the present utility model (6) slides by screw mandrel (5), and screw mandrel (5) is rotated by worm and gear by motor M (4).
Working method of the present utility model:
One, the forward or reverse of motor M (4) control: under the normal condition, descending stroke gauge tap SW1 (3) and upward stroke gauge tap SW2 (1) are in normally off, a switch in two of manual switches that hand controller is set is separately pressed, a corresponding relay J 1 or J2 adhesive, connect and be DC24V, and another relay J 2 or J1 be by normally closed ground connection, the output interface energising, motor M (4) is rotated, and two switches of hand controller are controlled the forward or reverse of motor M (4) respectively.
Two, Stroke Control: when the bell alive (6) that is driven by motor M (4) slides into the termination of guide rail (2), descending stroke gauge tap SW1 (3) or upward stroke gauge tap SW2 (1) disconnect, electric current ends by diode is anti-phase, motor M (4) is out of service, when motor M (4) commutation, by the anti-phase starter motor M of diode (4), make the travel switch of disconnection be in normally off, thereby realize motor M (4) operate as normal.
Three, motor M (4) is carried out overcurrent protection: motor M (4) electric current is by resistance R 6 samplings; when electric current reaches ratings; by stall (overcurrent) protection and the stall lock function of triode Q1, triode Q2, triode Q3 realization motor M (4), the manual switch that must unclamp hand controller behind the rotation-clogging protection just can unlock.
Claims (3)
