Commodity vending robot and cabin door driving mechanism
Technical Field
The embodiment of the invention relates to the field of commodity selling, in particular to a commodity selling robot and a cabin door driving mechanism.
Background
The commodity vending robot is a new concept vending mode, a user can order on the internet through a mobile terminal or the internet, and the robot can automatically move to the position of the user according to the position information of the ordering user to sell the commodity. After the commodity vending robot reaches the position of the user, the cabin door can be automatically opened by the commodity vending robot, and the commodity is selected by the user.
The inventor has found that existing hatch mechanisms include two hatches, an annular ring gear, two gears meshed with the annular ring gear, and two small motors driving the movement of the two hatches. Because two small-size motors need to follow two hatch doors and move together respectively, and can have some cables on the motor inevitably, in addition because the cable is flexible, cause the condition of strain or fracture very easily in some special cases, influence the normal operating of motor.
