Description
Technical Field
The utility model relates to a fixed knot of children's seat constructs, especially relates to a dead lever structure under steel aluminium hybrid car seat ISOFIX.
Background
ISOFIX (International Standards Organization FIX) child safety seat attachment system. ISOFIX is a new standard for the placement of child seats in automobiles. The effect is that the installation of the child seat becomes quick and simple, the rigid connection and it is safer. The ISOFIX-equipped child seat can be easily fixed in an ISOFIX interface of an automobile, so that the safety is improved;
the ISOFIX interface is already assembled in the automobile when the automobile leaves the factory. The child seat manufacturer installs the ISOFIX joint on the child seat. Thus, the ISOFIX child seat can be easily fixed in the ISOFIX interface of the automobile.
The ISOFIX interface devices in automobiles are also graded according to the size of the seats to be accommodated by the child seat, and are graded into 7 grades according to the size of the seat to be accommodated by the child seat, and generally, automobile manufacturers produce automobile seats accommodating all ISOFIX size grades. In addition, the ISOFIX universal and semi-universal seats are only seats suitable for use by children under the age of about 4 and from 0 to 18 kg. Other groups only use special types and can only match with individual vehicle types. The interface on a typical vehicle is not visible.
In the prior art, the ISOFIX dead lever of steel seat mostly is the steel wire and bends and form, then on direct welding or weld the seat skeleton through linking bridge, its structural strength required height, and figure 1 shows, prior art's linking bridge 1 and prior art backrest tubular beams 2 and prior art's dead lever 3 are all steel, so adopt the welded mode just can fix each other usually.
In the structural design of the aluminum alloy seat framework, if the ISOFIX lower fixing rod is made of aluminum materials, the strength of the ISOFIX lower fixing rod cannot meet the requirements of regulations, so that the ISOFIX lower fixing rod still adopts a steel wire structure, but because the framework main body is of an aluminum alloy structure, the problem of solving the steel-aluminum mixed connection process is faced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a fixed knot constructs, can satisfy the skeleton main part and adopt aluminum alloy structure ISOFIX lower dead lever to adopt steel material's manufacturing process requirement to solve the problem of steel aluminium hybrid connection technology.
The technical scheme of the utility model a dead lever structure under steel aluminium hybrid car seat ISOFIX is provided, it includes: aluminium system backrest tubular beam, aluminium system support frame, steel connecting plate rivet, steel dead lever, steel connecting plate, its characterized in that:
the steel fixing rod is formed by bending a steel wire, and the steel connecting plate is used for realizing the connection between the steel fixing rod and the aluminum supporting frame; the steel connecting plate is L-shaped and comprises a first part parallel to the aluminum supporting frame and a second part vertical to the aluminum supporting frame, wherein bent parts at two ends of the steel fixing rod are fixedly connected with the first part of the steel connecting plate in a welding mode; the second part of the steel connecting plate is fixedly connected with the aluminum support frame through a steel connecting plate rivet; the aluminum support frame is fixed with the aluminum backrest tubular beam.
Further, the aluminum support frame is designed with a support frame through hole.
Further, the diameter of the steel wire is 6 mm.
The utility model has the advantages that:
(1) the structure part is simple in process, the aluminum alloy fixing support is formed by adopting an extrusion process, the structure is simple, but the strength is good, and the whole structure can well meet the requirement of regulation strength.
(2) The structure well solves the problem of the connection process between steel and aluminum mixtures.

Detailed Description
The technical solution of the present invention is further explained in detail with reference to fig. 2-3.
As shown in fig. 2, the fixing rod structure under ISOFIX of the steel-aluminum hybrid car seat according to the embodiment includes: the structure comprises an aluminum seat backrest tubular beam 4, a support frame through hole 5, an aluminum support frame 6, a steel connecting plate rivet 7, a steel fixing rod 8 and a steel connecting plate 9;
the steel fixing rod 8 is formed by bending a steel wire with the diameter of 6mm and is used for installing and fixing the automobile child seat.
As shown in fig. 3, the steel connecting plate 9 is mainly used for connecting the steel fixing rod 8 and the aluminum supporting frame 6. The steel connecting plate 9 is L-shaped and comprises a first part parallel to the aluminum supporting frame 6 and a second part perpendicular to the aluminum supporting frame 6, wherein bent parts at two ends of the steel fixing rod 8 are fixedly connected with the first part of the steel connecting plate 9 in a welding mode.
