Abstract

The utility model discloses a back-row seat of a truck. The back-row seat comprises a backrest framework, a base framework and an annular moving foot support, wherein the rear end of the base framework is hinged to the backrest framework, the hinge end of the annular moving foot support is hinged to the bottom of the front end of the base framework, and an annular moving foot support synchronous turning mechanism capable of enabling the annular moving foot support and the base framework to turn and fold synchronously is arranged between the drive end of the annular moving foot support and the backrest framework. The back-row seat has the advantages that the annular moving foot support and the base framework can be folded synchronously, the usable space of a cab is increased, and the space utilization rate of the cab is improved.

Description

Truck back seat

Technical field

The utility model relates to automotive seat, is specifically related to truck back seat.

Background technology

The structure that is installed at present the truck back seat of truck cap back seat is: comprise backrest frames, be fixed with base skeleton on backrest frames, be fixed with the gyration foot support in order to base for supporting skeleton in the bottom, outer end of base skeleton; The shortcoming of this truck back seat is to overturn foldingly, no matter whether truck back seat is idle, all needs fixedly to take larger operator's compartment back seat space, has greatly reduced the degree of utilization in truck cap space.

Utility model content

The purpose of this utility model is to provide the folding truck back seat of a kind of energy.

For achieving the above object, the utility model has adopted following technical scheme: described truck back seat, comprise: backrest frames, base skeleton and gyration foot support, rear end and the backrest frames of base skeleton are hinged, the front bottom end of the pin jointed end of gyration foot support and base skeleton is hinged, and is provided with and can makes gyration foot support and base skeleton synchronize the gyration foot support synchronous turnover mechanism that upset folds between the drive end of gyration foot support and backrest frames.

Further, aforesaid truck back seat, wherein: the structure of described gyration foot support synchronous turnover mechanism is: comprise gyration pull bar, the drive end of the drive end of gyration pull bar and gyration foot support is hinged, the backrest frames of the pin jointed end of gyration pull bar and base skeleton below is hinged, and the shape of gyration pull bar guarantees that base skeleton and gyration foot support can completely inwardly overturn and fold.

Further, aforesaid truck back seat, wherein: the front end at base skeleton is also provided with base hook.

By the enforcement of technique scheme, the beneficial effects of the utility model are: in the time that truck back seat is on the shelf, can pack up folding to base skeleton and gyration foot support, thereby increase the utilized space of operator's compartment, improve the space availability ratio of operator's compartment.

Accompanying drawing explanation

Fig. 1 is the structural representation of truck back seat described in the utility model.

Fig. 2 is the structural representation of the left apparent direction of Fig. 1.

Fig. 3 is the view that the base skeleton shown in Fig. 1 and gyration foot support overturn while packing up.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As Fig. 1, Fig. 2, shown in Fig. 3, described truck back seat, comprise: backrest frames 1, base skeleton 2 and gyration foot support 3, the rear end of base skeleton 2 is hinged with backrest frames 1 by the first adapter shaft 4, the pin jointed end of gyration foot support 3 is hinged by the second adapter shaft 5 and the front bottom end of base skeleton 2, between the drive end of gyration foot support 3 and backrest frames 1, be provided with and can make gyration foot support 3 and base skeleton 2 synchronize the gyration foot support synchronous turnover mechanism that overturns and fold, in the present embodiment, the structure of described gyration foot support synchronous turnover mechanism is: comprise gyration pull bar 6, the drive end of gyration pull bar 6 is hinged by the 3rd adapter shaft 7 and the drive end of gyration foot support 3, the pin jointed end of gyration pull bar 6 is hinged by the 4th adapter shaft 8 and the backrest frames 1 of base skeleton 2 belows, the shape of gyration pull bar 6 can guarantee that base skeleton 2 and gyration foot support 3 can completely inwardly overturn and fold, this gyration foot support synchronous turnover mechanism simple in structure, installation and maintenance are convenient, can not only realize gyration foot support 3 inwardly overturns and folds together with backrest frames 1, increase the utilized space of operator's compartment, and when truck back seat is in the time using state, gyration pull bar 6 just in time stretching between gyration foot support 3 and backrest frames 1, gyration foot support 3 can more stably be supported base skeleton 2, thereby gyration foot support 3 can not be shaken in vehicle traveling process, stability and the safety of equipment are improved, in the present embodiment, front end at base skeleton 2 is also provided with base hook 9, in practical operation, can match with base hook 9 by conventional backpack strip, realizing the base skeleton 2 folding overturning is fixed, after the completely inside upset of base skeleton 2 and gyration foot support 3 folds, one end of backpack strip can be fixed on backrest frames 1, the other end of backpack strip is hooked on base hook 9, thereby complete the fixing of base skeleton 2 that upset is folded and gyration foot support 3, easy to operate.

Principle of work of the present utility model is as follows: the front end of base skeleton 2 is upwards lifted, base skeleton 2 is upwards overturn around the first adapter shaft 4, base skeleton 2 drives gyration foot support 3 upward movements that are hinged with it, the drive end upward movement of the moving pull bar 6 of gyration foot support 3 Timing Belt rotating rings, makes gyration pull bar 6 upwards rotate around the 4th adapter shaft 8; Along with the continuation of base skeleton 2 is upwards overturn, the drive end of gyration foot support 3 can inwardly rotate around the second adapter shaft 5 under the effect of contraction of gyration pull bar 6, until base skeleton 2 completely inwardly overturns and folds with gyration foot support 3, thereby complete base skeleton 2 and the inside folding of synchronizeing of gyration foot support 3, increased the utilized space in operator's compartment; The above-mentioned front end that has completed the base skeleton 2 folding is overturn downwards around the first adapter shaft 4, base skeleton 2 synchronously drives the gyration foot support 3 being hinged with it to move downward, gyration foot support 3 drives the drive end of gyration pull bar 6 to move downward, and gyration pull bar 6 is rotated around the 4th adapter shaft 8; Along with the continuation of base skeleton 2 is overturn downwards, the drive end of gyration foot support 3 can outwards rotate around the second adapter shaft 5 under the effect of contraction of gyration pull bar 6, until base skeleton 2 turn to initial position with gyration foot support 3, at this moment gyration pull bar 6 just in time stretching between gyration foot support 3 and backrest frames 1, gyration foot support 3 can more stably be supported base skeleton 2, by aforesaid operations, complete base skeleton 2 and outwards launched action with synchronizeing of gyration foot support 3; In the time that truck back seat is on the shelf, the upset of base skeleton 2 being synchronizeed with gyration foot support 3 is packed up like this, thereby has increased the utilized space of operator's compartment, has improved the space availability ratio of operator's compartment.
