Problems solved by technology

[0004] The purpose of the present invention is to provide a retractable mechanism for convenient opening and closing of the door panel in the vehicle-mounted toilet, so as to solve the problem that in the existing vehicle-mounted toilets, swing doors are mostly used, and locks are arranged inside the swing doors. The structure is simple and the use cost is low, but it takes up The space is large, and it is extremely inconvenient for the elderly, children, sick and disabled. Users need to open the bathroom door by themselves, which is prone to falls during driving; after entering the bathroom, the door panel needs to be closed and locked, which is inconvenient to use during driving , the general electric door opening button is set on the armrest, although it is convenient, it is easy to touch by mistake; in case of emergency, such as motor damage, power failure, etc., the general electric door cannot be opened manually, and it needs to be opened with a crowbar or after maintenance , using a crowbar will damage the door panel and cause too much loss, maintenance will delay time, and the user will be trapped inside for a long time
