Description
Technical field
The present invention relates to a kind of seat, especially one kind can be installed on subway, EMUs, the seat of convenient commutation.
Background technology
At present in the EMUs running of operation during commutation traveling, be mostly by rotary seat conversion direction, so as to
It is identical with current of traffic improving ride quality.Due to limited space between front and rear row seat during rotary seat, therefore often
Secondary commutation will front and rear row operate simultaneously and cause great inconvenience.
The content of the invention
In order to overcome the shortcomings of that the commutation of existing seat is inconvenient, comfort level is poor, the present invention provides that a kind of commutation is convenient, carries
Rise the commutation seat of comfort level.
The technical solution adopted for the present invention to solve the technical problems is：
One kind commutation seat, including backrest, kinematic link, outboard gears connecting rod, inboard gear connecting rod, bearing and driving cog
The kinematic link, the inner side of the kinematic link and the upper end of inboard gear connecting rod are fixed respectively in wheel, the both sides of the backrest
It is hinged, outside and the upper end of outboard gears connecting rod of the kinematic link are hinged, the lower end of the inboard gear connecting rod is provided with interior
Side toothed region, the inner side toothed region is engaged with travelling gear, and the travelling gear is arranged on bearing, and the inboard gear connects
The lower end of bar is connected with bearing by bearing；The lower end of the outboard gears connecting rod is provided with outside toothed region, the outside profile of tooth
Portion engages with travelling gear, and the lower end of the outboard gears connecting rod is connected with bearing by bearing.
Further, the outside toothed region is outboard gears, and the outboard gears are fixed with the lower end of outboard gears connecting rod；
The lower end of the inboard gear connecting rod is in partial gear, and the partial gear is inner side toothed region.
Further, the seat also includes handrail and protection shell, and handrail is connected with backrest, and the protection shell is fixed
In the both sides of bearing.
Further, the rest base is distributed the screw for fixing seat.
The present invention technology design be：For convenience of seat commutation, the present invention can just reach commutation using only invertible back support
Purpose, and the angle of inclination that commutate rear backrest and seat remain to keep certain not only simplify seat switch operation and guarantor
The comfortableness of seat is held.It is contemplated that the present invention may be use with subway, so as to improve present city in the seat of rows that adopts
Chair, lifts ride quality.
Beneficial effects of the present invention are mainly manifested in：The commutation armchair structure is simple, easy to operate, only need to promote handrail
Dynamic backrest carries out being inverted to the commutation for completing seat, and backrest can keep certain inclination angle with bearing before and after seat commutation
Degree, improves the comfortableness of seat.

Specific embodiment
Below in conjunction with the accompanying drawings the invention will be further described.
With reference to Fig. 1~Fig. 8, one kind commutation seat, including backrest 12, kinematic link 21, outboard gears connecting rod 22, inner tines
The kinematic link 21 is fixed respectively in wheel connecting rod 23, bearing 14 and travelling gear 24, the both sides of the backrest 12, and the transmission connects
The inner side of bar 21 is hinged with the upper end of inboard gear connecting rod 23, and the outside of the kinematic link 21 is upper with outboard gears connecting rod 22
End is hinged, and the lower end of the inboard gear connecting rod 23 is provided with inner side toothed region, and the inner side toothed region is engaged with travelling gear 24,
The travelling gear 24 is installed on base 14, and the lower end of the inboard gear connecting rod 23 is connected with bearing 14 by bearing；Institute
The lower end for stating outboard gears connecting rod 22 is provided with outside toothed region, and the outside toothed region is engaged with travelling gear 24, the outside
The lower end of gear connecting rod 22 is connected with bearing 14 by bearing.
Further, the outside toothed region is outboard gears, and the outboard gears are fixed with the lower end of outboard gears connecting rod；
The lower end of the inboard gear connecting rod is in partial gear, and the partial gear is inner side toothed region.
Further, the seat also includes handrail 11 and protection shell 13, and handrail 11 is connected with backrest 12, the protection
