The invention provides a vehicle-mounted vending machine which comprises a cabinet body, a lifting platform and a pickup opening. Guide rails facilitating the vertical motion of the lifting platform are arranged in the middle of the cabinet body, the pickup opening is formed in the upper side of the position, at the upper ends of the guide rails, of the cabinet body, a lifting motor driving the lifting platform to vertically move is arranged at the bottom or the top of the position, at the lower ends of the guider rails, of the cabinet body, and a lifting transmission mechanism driving the lifting platform to do synchronous movement is connected between the lifting motor and the lifting platform. Separation plates which divide an inner cavity of the cabinet body into a left warehouse and a right warehouse are arranged at the positions, on two sides of the guide rails, inside the cabinet body, goods channels are arranged at the bottoms of the warehouses respectively, a plurality of driving wheels feeding goods in the warehouses into the goods channels are arranged on the upper sides of the goods channels, track pushing devices for conveying the goods to the lifting platform are arranged in the goods channels, and correction mechanisms preventing articles from being transverse in the goods channel conveying process are arranged in the positions, above the track pushing devices, of the goods channels. The correction mechanisms effectively prevent a vehicle-mounted movable platform from influencing article conveying in the moving process, and the reliability of outputting the goods is improved.
