Abstract: A frame structure includes a frame body and an auxiliary frame fixedly connected to the frame body. The frame body has a front bracket and a frame base. The lower end of the front bracket does not connect with the frame base. The upper end portion of the auxiliary frame is connected to the front bracket of the frame body, and the lower end of the auxiliary frame is connected to the frame base at the rear of front wheels of the frame. A trolley with the frame structure can prevent it from leaning forward or overturning, which increases security and stability.

Abstract: Disclosed is a security control device comprising a connector including a male plug having a first electrode, a female socket having a second electrode, a first control component on first electrode side and a second control component on the second electrode side, and a detection control switch. When a current connector and its anterior connector connect, a first control component of the current connector and a second control component of the anterior connector are coupled by way of non-contact sensing after a first electrode of the current connector and a second electrode of the anterior connector contact; and when the two connectors disconnect, the first control component of the current connector and the second control component of its anterior connector are decoupled before the first electrode of the current connector and the second electrode of the front connector separate. Also disclosed are a charging device and a trolley.

Abstract: Disclosed is a mobile self-service method and a system including a movable service terminal configured to acquire, verify and parse user data to obtain flight number information about a user; a background service system configured to interact with the movable service terminal and provide service data in response to a request sent from the movable service terminal. The terminal is further configured to interact with the background service system to verify the flight number information, confirm a corresponding flight, establish real-time indoor positioning information about the movable service terminal, and provide a navigation prompt from the current position to a corresponding boarding gate or a specified position according to the service data and the real-time positioning information. The present invention can provide personalized flight information, positioning and navigation prompts to passengers waiting for flights in airports, provide path planning and estimate the required time.
