Abstract
The invention discloses a mounting structure of a safety belt of a rear seat of a truck. The mounting structure of the safety belt of the rear seat of the truck comprises two rear seat safety belt buckle assemblies and two mounting components, each mounting component is located in a cavity formed between the rear side wall of a rear floor and a rear floor reinforcing plate and comprises a component body and welding nuts, the component body comprises a bottom and three turnover lateral surfaces, a weld joint surface is arranged at the lower end of the bottom, the welding nuts are welded on the bottom, the mounting component is welded and fixed on the rear floor reinforcing plate through welded flanges and the weld joint surface, and the bottom of the component body is firmly jointed with the rear floor; the rear seat safety belt buckle assemblies are connected with the welding nuts on the corresponding mounting components through screws of mounting parts on the assemblies. The mounting structure of the safety belt of the rear seat of the truck is capable of effectively using the bending resistance coefficients of the cavity section, improving the mounting intensity of the rear seat safety belt of the truck, solving the problem of plastic deformation of the rear floor made of a cold rolled low-carbon steel plate, and meeting the requirements of the national mandatory regulations.
Description
Technical field
The present invention relates to automobile body components, be specifically related to a kind of lorry rear row seat belt mounting structure.
Background technology
Car belt is as national compulsory laws and regulations requirement, and in automobile design, to safety strap, mounting structure intensity, the installing space etc. on vehicle body requires all higher.
Existing lorry rear row seat belt mounting structure as shown in Figure 6, comprise two rear row seat safety belt lock catch assemblies 1, rear floor 2, two installation components 6 and installation component deep beams 5, described installation component is simple schistose texture, it is directly welded and fixed with the bottom surface on rear floor, two rear row seat safety belt lock catch assemblies are assemblied in respectively on corresponding installation component, cross section is that U-shaped installation component deep beam is welded on two installation components, forms a rectangular cavity and plays the effect of strengthening structural strength.But existing lorry rear row seat belt mounting structure is mainly subject to twisting action power, fails to make full use of the bending resistant section coefficient of this rectangular cavity.Adopt Q/BQB403-2003(cold continuous rolling mild steel plate and steel band on rear floor) when series material, rear floor plastic deformation in existing belt mounting structure is serious, analyze through CAE demonstration, above-mentioned cavity cross section exists and draws routed risk, can not meet the requirement of strength of the belt anchorage point in the test method of national compulsory regulation GB14167-2006 " car belt attachment point ".
Summary of the invention
The object of the present invention is to provide a kind of lorry rear row seat belt mounting structure, to improve the fixed installation intensity of rear row seat safety strap, make it meet state compulsion laws and regulations requirement.
Lorry rear row seat belt mounting structure of the present invention, comprise two rear row seat safety belt lock catch assemblies and two installation components, described rear row seat safety belt lock catch assembly comprises the installation portion that is provided with screw rod, in the chamber that described installation component forms between the rear sidewall on rear floor and rear floor brace panel, this rear floor brace panel and rear floor welded are fixed, described installation component comprises member bodies and welded nut, member bodies is an integrated sheet-metal part, it comprises bottom surface and three sides that are folded into, described side lays respectively at the left end of bottom surface, right-hand member and upper end, be provided with welding binding face in the lower end of bottom surface, be equipped with outside welding flange in lateral edge, described welded nut is weldingly fixed on the bottom surface of member bodies, installation component is weldingly fixed on the brace panel of rear floor by described welding flange and welding binding face, the Yu Hou floor, bottom surface of member bodies fits tightly, the screw rod of described two rear row seat safety belt lock catch assemblies by the installation portion on it connects with the welded nut on corresponding installation component respectively.
Further, described welded nut is T-shaped welded nut.
Beneficial effect of the present invention is: by installation component being assemblied in the chamber that Yu Hou floor, rear floor brace panel forms, utilize the attachment point of this chamber as rear row seat safety strap, this installation component is compared with existing sheet installation component, structural strength is higher, and this installation component has played to described chamber the effect of strengthening.Therefore mounting structure of the present invention can effectively utilize the bending coefficient in chamber cross section, thereby improve the installation strength of lorry rear row seat safety strap, solve the problem that adopts the rear floor plastic deformation of cold continuous rolling mild steel plate, made this mounting structure can meet the requirement of state compulsion regulation.
