Vehicle truss-type anti-descending girder structure and connection thereof

Abstract

The invention discloses a vehicle truss-type anti-descending girder structure. The vehicle truss-type anti-descending girder structure comprises a supporting pipe, a lock catch structure and a fixed base, the two ends of the supporting pipe are fixedly connected with the lock catch structure separately, and the lock catch structure is in bolted connection with the fixed base; a communicating holeis transversely formed in the lock catch structure, and the two ends of the supporting pipe are fixed to the communicating hole of the lock catch structure separately. The invention further disclosesthe vehicle truss-type anti-descending girder structure and connection thereof. The supporting pipe replaces a traditional anti-descending girder with a complicated girder system, and is high in rigidity, low in weight and low in manufacturing cost; the upper portion of the supporting pipe is in contact with a lower foam plate at a back row seat, and the situation that the body of a back seat passenger gets hurt before moving downwards when a cushion of the back row seat descends while a vehicle is collided can be effectively lowered; a floor and the upper surface of the fixed base are paved with a carpet, the supporting pipe does not need to be paved with the carpet, and it is avoided that the cavity echoes are generated when the upper surface of the traditional anti-descending girder ispaved with the carpet, and the cavity inside the anti-descending girder cannot be filled.

Description

technical field [0001] The invention belongs to the technical field of automobile rear floor installation, in particular to an automobile truss type anti-submersion beam structure and its connection. Background technique [0002] At present, the rear floor of the vehicle is usually designed relatively flat, and most of them lack the anti-submersion beam of the rear seat. When the car collides, the rear occupants are prone to dive and move forward, causing the rear occupants to be injured. [0003] In order to improve the safety factor of passengers in the rear row, various anti-submersion beam structures have been manufactured and used successively. For example, the Chinese patent application number 201520861810.6 announces a "seat anti-submersion beam", which is composed of an anti-submersion beam body, a left mounting plate, a right mounting plate and two support plates; the two support plates are welded on the anti-submersion Inside the beam body; the left mounting plate...

AI Technical Summary

Problems solved by technology

For example, the Chinese patent application number 201520861810.6 announces a "seat anti-submersion beam", which is composed of an anti-submersion beam body, a left mounting plate, a right mounting plate and two support plates; the two support plates are welded on the anti-submersion Inside the beam body; the left mounting plate and the right mounting plate are installed on the left end and the right end of the anti-submersion beam body respectively, and are respectively welded on the anti-submergence beam body by flanging. The whole anti-submergence beam body is in the form of continuous bending, and the seat The anti-submersion beam is fixed on the upper panel of the rear seat beam and the rear floor by 8 bolts. The mass is large, the installation bolts are many, and the versatility is poor, and the cavity formed inside the anti-submersion beam body is prone to cavity echo; another example is the application The Chinese patent No. 201220356528.9 announced a "car rear floor with a rear seat anti-submersion beam structure", including a rear floor body, and a rear seat is provided above the front end of the rear floor body and directly below the rear seat. The anti-submersion beam, the cross-section of the anti-submersion beam of the rear seat is in the shape of "Ji", the bottom edge and both ends of the anti-submersion beam of the rear seat are welded with the rear floor body to form the first closed cavity, The top surface of the seat anti-submersion beam is provided with mounting holes for installing the rear seat. This type of rear seat anti-submersion beam also has the problems of high quality and poor NHV performance
