Abstract
The utility model discloses a kind of low floor vehicle chair of glass fibre reinforced plastic, back cushion skeleton is made up of with the steel plate of stud the end of at least three levels, and back cushion skeleton is fixed with back cushion; Seat cushion framework be U-steel be spliced into the framework beam of square frame-shaped and side with stud, seat cushion is fixed on seat cushion framework; The side girders of seat is L shape and side straps " U " shape mouth, builtin-nut block is had in " U " shape mouth of side girders, be fixed on builtin-nut block by the stud on back cushion skeleton in " U " shape mouth that the both sides of back cushion skeleton and back cushion are inserted into side girders standing portion, be fixed on builtin-nut block by the stud on it in " U " shape mouth that the both sides of seat cushion framework and seat cushion are inserted into side girders level, seat cushion framework is fixed on the floor box mount pad of low floor vehicle.The utility model structure is simple, can solve the long-time seat that uses easily loosens and dismantles difficult problem, improves traveling comfort, can meet the requirement of vehicle weight-saving.
Description
Technical field
The utility model belongs to urban rail transit technology field, specifically relates to a kind of low floor vehicle chair of glass fibre reinforced plastic.
Background technology
Along with the development of urban track traffic, the car body lightweight of guideway vehicle, fire resistance, damping noise reduction and travelling comfort are important subject always.The design concept of " people-oriented ", not only requires that vehicle possesses higher safety, more needs the design indicates hommization of vehicle, traveling comfort.Low floor vehicle more and more welcomed by the people, but the seat on low floor vehicle is also diversified, the existing stainless seat also having glass-felt plastic.Existing chair of glass fibre reinforced plastic great majority by cushion frame, back cushion and seat cushion three part form, mounting means is first arranged on steel structure of car body by cushion frame, and then back cushion and seat cushion are inserted in the draw-in groove of skeleton respectively, then with bolt, chair of glass fibre reinforced plastic face and cushion frame are linked together.Because back cushion and seat cushion directly insert in skeleton draw-in groove, make the dismounting difficulty of seat, efficiency is low, and the seat after dismounting can not keep in repair again and seat easily damages in unloading process, and the cost of seat is increased.And be connected and fixed by means of only the clamping force inserting skeleton draw-in groove, if used for a long time, there will be loosening, in motion, rocking appears in seat, and then has influence on the traveling comfort that passenger takes.This chair of glass fibre reinforced plastic self structure makes the total weight of seat too large, is also not suitable for vehicle weight-saving target.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art, provide a kind of structure simple, can effectively avoid using for a long time seat to occur loosening, the low floor vehicle chair of glass fibre reinforced plastic of dismounting difficulty, thus reach low floor vehicle weight-saving object.
The purpose of this utility model is achieved through the following technical solutions, a kind of low floor vehicle chair of glass fibre reinforced plastic, and back cushion skeleton is made up of with the steel plate of stud the end of at least three levels, and back cushion skeleton is fixed with back cushion; Seat cushion framework be U-steel be spliced into the framework beam of square frame-shaped and side with stud, seat cushion is fixed on seat cushion framework; The side girders of seat is L shape and side straps " U " shape mouth, builtin-nut block is had in " U " shape mouth of side girders, be fixed on builtin-nut block by the stud on back cushion skeleton in " U " shape mouth that the both sides of back cushion skeleton and back cushion are inserted into side girders standing portion, be fixed on builtin-nut block by the stud on it in " U " shape mouth that the both sides of seat cushion framework and seat cushion are inserted into side girders level, seat cushion framework is fixed on the floor box mount pad of low floor vehicle.
In order to realize the purpose of this utility model better, described seat cushion framework is near the both ends of the framework beam at seat edge with seat adapter plate, and screw is fixed through side girders and seat adapter plate nut.
In order to realize the purpose of this utility model better, described back cushion is provided with builtin-nut block, is fixed on the steel plate of back cushion skeleton by stud.
In order to realize the purpose of this utility model better, described seat cushion is provided with builtin-nut block, is fixed on the framework beam of seat cushion framework by stud.
In order to realize the purpose of this utility model better, the framework material of described back cushion skeleton, seat cushion framework and seat adapter plate all adopts Q345E.
The beneficial effect of the utility model low floor vehicle chair of glass fibre reinforced plastic is, by changing the skeleton structure of seat and the connection mode with back cushion and seat cushion, and then solve long-time use, the problem that seat easily loosens and dismounting is difficult, structure is simple, easy installation and removal, improves traveling comfort, can meet the requirement of vehicle weight-saving.

Detailed description of the invention
For making goal of the invention of the present utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, carry out knowing to the technical solution of the utility model and intactly describe, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
See accompanying drawing, the utility model low floor vehicle chair of glass fibre reinforced plastic, back cushion skeleton 1 is made up of with the steel plate of stud the end of four levels, and back cushion 3 is provided with builtin-nut block 8, is fixed on back cushion skeleton 1 by stud; Seat cushion framework 2 for U-steel be spliced into the framework beam of square frame-shaped and side with stud, be embedded with nut block 8 in seat cushion 4, be fixed to by stud on the framework beam of seat cushion framework 2; The side girders 6 of seat is L shape and side straps " U " shape mouth, builtin-nut block 8 is had in " U " shape mouth of side girders 6, be fixed on builtin-nut block 8 by the stud on back cushion skeleton 1 in " U " shape mouth that the both sides of back cushion skeleton 1 and back cushion 3 are inserted into side girders 6 standing portion, be fixed on builtin-nut block 8 by the stud on it in " U " shape mouth that the both sides of seat cushion framework 2 and seat cushion 4 are inserted into side girders 6 level, seat cushion framework 2 is fixed on the floor box mount pad 5 of low floor vehicle.
In order to improve intensity, at seat cushion framework 2 near the both ends of the framework beam at seat edge with seat adapter plate 7, screw is fixed with nut through side girders 6 and seat adapter plate 7.
The framework material of back cushion skeleton 1, seat cushion framework 2 and seat adapter plate 7 all adopts Q345E.Because framework material adopts Q345E, back cushion 3 and seat cushion 4 adopt has good mechanical properties, light specific gravity, good toughness, resistance to fire-retardant glass fiber reinforced plastics composite material, therefore, light than other seat-weights similar.
The chair of glass fibre reinforced plastic dismounting of this mounting means is easier.
