Description

Bus seat skeleton

Technical field

The utility model is related to seating art field, more particularly to a kind of bus seat skeleton.

Background technology

Required as automobile industry product is light-weighted, client it is also proposed more strict requirements to the weight of product. The backrest frames overwhelming majority is metal backrest used in the automobile chair of in the market, and manufacturing procedure is complicated, spends more In terms of man-hour, energy resource consumption, production raw materials for plastics production can save more energy than production raw material metal.Thermoplastic composite The cost that material is reused is smaller, and environment is hardly polluted.The density that it has is small, linear expansion coefficient compared with It is small, the shrinkage factor during product molding can be reduced（The precision of product size can be improved）Composite wood is greatly expanded etc. advantage Metal parts on material use in daily life, gradually alternative metals and timber, such as car.But the intensity of plastics Not strong with shock resistance, often service life is shorter for the product of preparation.The applying date is on November 27th, 2009, Application No. 200910199483. 1 Chinese patent, discloses a kind of car seat back frame of plastic material, and the skeleton is by moulding Expect that material is integrally formed, and the skeleton has the shell along its circumferentially extending, and the cross section of the shell is " n " type, And the inner side of the shell of the n tee sections has cellular reinforcement.Although the setting of reinforcement is improved to a certain extent The service life of product, but plastics differ greatly compared with the intensity and impact property of metallic article.

The content of the invention

The purpose of this utility model is to provide that a kind of lightweight, intensity is high, service life length bus seat skeleton.

The purpose of this utility model is realized in the following manner：Bus seat skeleton, including n shape frameworks, in n shape frameworks Inner side is provided with reinforcement A, and backboard is connected with the inside of two side frames of n shape frameworks, and the backboard includes backrest plate face, The first reinforcement group, the second reinforcement group, the 3rd reinforcement group, the 4th reinforcement group, horizontal centre are provided with backrest plate face Reinforcement and vertical centre reinforcement, the first reinforcement group are symmetrical along vertical centre reinforcement with the second reinforcement group, the Three reinforcement groups and the 4th reinforcement group are symmetrical along vertical centre reinforcement, the first reinforcement group and the 3rd reinforcement group edge Horizontal centre reinforcement is symmetrical, and the second reinforcement group and the 4th reinforcement group are symmetrical along horizontal centre reinforcement, the One reinforcement group includes first reinforcement parallel with side frame, and the first reinforcement is vertical with the second reinforcement, and the first reinforcement is worn Cross the second reinforcement with the 3rd reinforcement to intersect, the 3rd reinforcement intersects with the 4th reinforcement and the 5th reinforcement respectively, the 4th Reinforcement is parallel with the second reinforcement, and the 4th reinforcement intersects with the 6th reinforcement and the 7th reinforcement respectively, the 6th reinforcement Arranged in a crossed manner with the 7th reinforcement, the 3rd reinforcement and the 7th reinforcement intersect with horizontal centre reinforcement respectively, horizontal centre Reinforcement intersects with the 8th reinforcement, and the 8th reinforcement intersects with the 9th reinforcement, and the 9th reinforcement and the tenth reinforcement are along Two reinforcements are symmetrical, the angle and the 11st reinforcement and the second reinforcement between the 8th reinforcement and the second reinforcement it Between angle it is equal, the 11st reinforcement intersects with the 12nd reinforcement.

The backboard upper and lower ends are provided with crossbeam, and cross rail inner is provided with reinforcement B.

The n shapes framework, backboard and crossbeam thermoplastic composite are integrally formed.

The reinforcement B is " N " type.

9th reinforcement is parallel with the second reinforcement.

The reinforcement A is " Z " type.

The beneficial effects of the utility model are：The utility model is simple and reasonable, can be used instead of metallic framework, safety Reliably, long lifespan, it is not only lighter than metallic framework in weight, and it is easy to processing and recycling.
