SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims at providing a motor damping mechanism and automatic vending machine that crashproof just can close tightly the door.
The utility model adopts the technical proposal that:
a motor damping mechanism for a vending machine door closing, comprising: the control panel, the motor and the rack; the control panel is used for driving the motor to rotate forwards and backwards; the motor is electrically connected with the control board and is arranged on the cabinet body, and an output shaft of the motor is provided with a gear; one end of the rack is pivotally connected to the cabinet door, and the other end of the rack is meshed with the gear.
Further, motor damping mechanism still includes installing support and gyro wheel, motor, gyro wheel, gear and rack all install in on the installing support, the installing support is fixed in the cabinet body, the gyro wheel attached in the rack rear side is in order to be used for compressing tightly rack and gear.
Furthermore, an output shaft of the motor is provided with an upper flange bearing and a lower flange bearing which are positioned on the upper side and the lower side of the gear.
Furthermore, the winding of the motor is connected with an A/D conversion unit for collecting voltage signals.
Preferably, the motor is a permanent magnet direct current brush motor.
This technical scheme still includes an automatic vending machine, including the cabinet body, with cabinet body articulated and the cabinet door that can kick-back and above-mentioned motor damping mechanism.
The utility model has the advantages that: the utility model discloses a motor damping mechanism that motor gear and rack constitute, driving motor reversal production resistance is with balanced resilience force when the cabinet door is kick-backed to avoid the cabinet body acutely to shake, and corotation increase resilience force when the cabinet door is close to the cabinet body, can close the cabinet door better, reduce the gap between the cabinet door and the cabinet body.

Detailed Description
As shown in fig. 1 and fig. 2, for the utility model discloses a motor damping mechanism for closing a door of an automatic vending machine, include: a control board (not shown), a motor 100, and a rack 200; the control board is used for driving the motor 100 to rotate forwards and backwards; the motor 100 is electrically connected with the control board and is arranged on the cabinet 500, and an output shaft thereof is provided with a gear 300; the rack 200 is pivotally connected to the cabinet door 400 at one end and engaged with the gear 300 at the other end.
Its theory of operation does, when opening the door, motor 100 is out of work, wait that the user loosens when cabinet door 400, rack 200 follows cabinet door 400 gyration, gear 300 with rack 200 meshing drives the rotation of motor 100 output shaft, thereby motor 100 winding produces induced voltage, control panel driving motor 100 reversal, motor 100 reversal produces the resistance with balanced resilience force, thereby avoid the violent vibrations of cabinet body 500, when cabinet door 400 is close to cabinet body 500 under motor 100 effect, cabinet door 400 tends to quiescent condition, control panel driving motor 100 corotation increases the resilience force this moment, can close cabinet door 400 better, reduce the gap between cabinet door 400 and the cabinet body 500.
As a further improvement of the present technical solution, the motor 100 mechanism of the present technical solution further includes a mounting bracket 600 and a roller 700, the motor 100, the roller 700, the gear 300 and the rack 200 are all mounted on the mounting bracket 600, the mounting bracket 600 is fixed to the cabinet 500, and the roller 700 is attached to the rear side of the rack 200 for compressing the rack 200 and the gear 300, thereby preventing the gear 300 from slipping.
In order to prolong the service life of the motor 100, an upper flange bearing 800 and a lower flange bearing 900 which are positioned at the upper side and the lower side of the gear 300 are arranged on the output shaft of the motor 100, so that the smoothness of the gear 300 during rotation is improved.
The induced voltage of the winding of the motor 100 is collected through the A/D conversion unit and fed back to the control board, the winding of the motor 100 is connected with the A/D conversion unit to be used for collecting voltage signals, and when the induced voltage disappears, the cabinet door 400 stops rebounding. Of course, other arrangements for collecting the induced voltage of the motor windings are possible, such as conventionally known voltage transformers. In this embodiment, the preferred motor 100 is a permanent magnet dc brush motor, and other electromagnetic motors, such as a shunt excitation dc motor and a series excitation dc motor, may also be used.
As shown in fig. 4, the technical solution further includes an automatic vending machine, which includes a cabinet 500, a door 400 hinged to the cabinet 500 and capable of rebounding, and the motor damping mechanism.
To sum up, the utility model discloses a motor damping mechanism that motor gear and rack 200 constitute, driving motor 100 reversal production resistance is with balanced resilience force when cabinet door 400 kick-backs to avoid cabinet body 500 to acutely shake, and corotation increase resilience force when cabinet door 400 is close to cabinet body 500, can close cabinet door 400 better, reduce the gap between cabinet door 400 and the cabinet body 500.
The above is only the preferred embodiment of the present invention, the present invention is not limited to the above embodiment, and the technical solution of the present invention is all within the protection scope of the present invention as long as the present invention is realized by the substantially same means.
