Rotating arm guide rail connecting structure

Abstract

The tumbler guide rail connecting structure comprises a vehicle body, a vehicle door, a guide rail, a tumbler and a tumbler seat, the guide rail is arranged on the inner surface of the vehicle door, the upper portion and the lower portion of a vehicle door frame or the side wall of one side of the vehicle door frame, the guide rail is composed of a linear section and a curved section, the linear section is arranged in the sliding direction of the door, and the curved section is connected to one end of the linear section; one end of the rotating arm is connected to the rotating arm base in a restrained and rotating mode, the other end of the rotating arm is provided with two or more rollers, the rollers rotate on roller shafts, the roller shafts are fixed to the rotating arm, and the rollers are restrained to roll on the guide rail. According to the structure on the passenger car, a middle guide rail does not need to be arranged on the side wall of the car body, and the sliding door can stably operate when opened or closed; or the structure can be applied to a non-bearing body motor bus, a middle guide rail is arranged on the side wall of the body without damaging the profile of the door frame skeleton, and the door is closed and opened by rotating the rotating arm to cross over the door frame.

Description

technical field [0001] The invention relates to the field of mechanical structures, in particular to a connecting structure of a rotating arm guide rail. Background technique [0002] The sliding door of the car needs to first slide the sliding door out of the body for a certain distance and then slide to the side. For example, in the current structure of the sliding door of MPV vehicles, a guide rail is fixed from the inside of the vehicle body to the surface of the vehicle body, and a roller trolley is connected to the inner surface of the vehicle door to roll in the guide rail chute to realize the sliding door to the side after the door leaves the vehicle body surface, so that there are guide rails on the surface of the vehicle body. Not pretty. However, for non-load-bearing structures such as buses, the guide rails from the body to the body surface cannot be used. Because the non-load-bearing body door frames of buses are made of profiles, the use of the above-mentioned...

Problems solved by technology

For example, the current structure of the sliding door of MPV is that guide rails are fixed from the inside of the car body to the surface of the car body, and the inner surface of the door is connected with a roller trolley that rolls in the guide rail chute to realize that the door leaves the body surface and then slides to the side to open the door, so that there are guide rails on the body surface. unsightly

And for the body of non-load-bearing structure, such as a bus, the guide rail from the body to the surface of the body cannot be used. Because the door frame of the non-load-bearing body of the bus is made of profiles, the use of the above-mentioned guide rails needs to be extended from the surface of the body through the profile of the door frame. It is not allowed to destroy the door frame made of profiles when entering the body, it will damage the strength of the door frame
