Abstract
The utility model relates to an enclose behind public transit car skeleton, including a lower extreme open -ended rectangular frame A, in the rectangular frame A from last under in proper order the level be equipped with a web beam, no. Two web beam and no. Three web beam, the rectangular frame A inboard still be equipped with one with the parallel and lower extreme open -ended rectangular frame B of rectangular frame A, three limits of rectangular frame B all are the arc, rectangular frame A and rectangular frame B connect fixedly through a plurality of perpendicular to rectangular frame A and the planar joining profile of rectangular frame B, the portion of placing still is equipped with a display panel installing zone behind the public transit car skeleton. The utility model has the advantages of: the utility model discloses technical scheme adopts full constructed of aluminium, greatly reduced the tare, the utility model discloses three limits of technical scheme's rectangular frame B all are the arc makes the appearance lines more smooth, and it is pleasing to the eye to have improved the product, the utility model discloses before can improving, encloses technical scheme's additional strengthening stability.
Description
Technical field
The utility model relates to a kind of aluminium profile structure, especially a kind of back wall of bus skeleton.
Background technology
At present, bus body structure form mainly contains: 1, Non-carrying type, has independent vehicle frame, vehicle body and vehicle frame flexible-disc joint, and carrying main body is vehicle frame; 2, half bearing-type, has independent vehicle frame, and vehicle body and vehicle frame are rigidly connected, and carrying main body is based on vehicle frame, and body portion participates in carrying.Can be there is chassis and vehicle body displacement in these two kinds traditional structures, vehicle body is easily out of shape and distortion, and integral strength is weak, and complete vehicle quality is large, and centroid position is high when being subject to clashing into, dynamic property and fuel economy poor.
For this reason, Chinese patent CN101503099A discloses one " the motorcoach unitary body of scale rectangular tube chassis ", comprise underframe, the two ends, left and right of underframe are fixed on left-side skeleton and right side wall skeleton respectively, left, at least one skeleton in right side wall skeleton is interval with along the longitudinal direction two inlet regions, the entrance underframe of bridge joint between described underframe is included in bottom the side wall frame at place, each inlet region and the side wall frame of offside, described underframe also comprises the transition chassis frame be connected between adjacent entries underframe, ledge structure is equipped with between each entrance underframe and transition chassis frame.Transition chassis frame need be set foot on by ledge structure by entrance underframe during passenger loading; Need be depressed by transition chassis frame by ledge structure and get off during passenger getting off car.Due to the existence of ledge structure, not only increase the height of vehicle body, and getting on or off the bus of passenger is brought inconvenience, often there will be passenger and block up in the situation of each inlet region.
At present, body framwork on market is made of iron, vehicle body is heavier, and energy resource consumption is larger, and also some body framwork adopts aluminum simultaneously, but structure is also unchanged, thus directly affects the various aspects of performance of vehicle body, therefore, be just badly in need of developing a kind of back wall that can meet the bus skeleton of the Combination property of all-aluminium body, through retrieval, do not find the same or analogous technical scheme with the utility model.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of back wall that can meet the bus skeleton of the Combination property of all-aluminium body.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of back wall of bus skeleton, it is characterized in that: the rectangular frame A comprising a lower ending opening, in described rectangular frame A under upper successively level be provided with a deep beam, No. two deep beams and No. three deep beams, and the rectangular frame B of lower ending opening parallel with rectangular frame A is also provided with inside described rectangular frame A, three limits of described rectangular frame B are all curved, described rectangular frame A and rectangular frame B is connected and fixed by some connection profiles perpendicular to rectangular frame A and rectangular frame B plane.
Further, after described bus skeleton, upper part is also provided with a display panel installing zone.
The utility model has the advantage of: technical solutions of the utility model adopt all-aluminium construction, greatly reduce tare; The all curved profile lines that make in three limits of the rectangular frame B of technical solutions of the utility model are more smooth, improve product attractive in appearance; The reinforcement structure of technical solutions of the utility model can improve front wall stability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the back wall of the utility model bus skeleton.
Fig. 2 is the lateral plan of the back wall of the utility model bus skeleton.
Detailed description of the invention
The back wall of a kind of bus skeleton as depicted in figs. 1 and 2, comprise the rectangular frame A51 of a lower ending opening, in rectangular frame A51 under upper successively level be provided with a deep beam, No. two deep beams and No. three deep beams, and the rectangular frame B52 of lower ending opening parallel with rectangular frame A51 is also provided with inside rectangular frame A51, three limits of rectangular frame B52 are all curved, and rectangular frame A51 and rectangular frame B52 is connected and fixed by some connection profiles perpendicular to rectangular frame A51 and rectangular frame B52 plane.
After the bus skeleton of technical solutions of the utility model, upper part is also provided with a display panel installing zone.
Technical solutions of the utility model adopt all-aluminium construction, greatly reduce tare; The all curved profile lines that make in three limits of the rectangular frame B52 of technical solutions of the utility model are more smooth, improve product attractive in appearance; The reinforcement structure of technical solutions of the utility model can improve front wall stability.
More than show and describe groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. the back wall of a bus skeleton, it is characterized in that: the rectangular frame A comprising a lower ending opening, in described rectangular frame A under upper successively level be provided with a deep beam, No. two deep beams and No. three deep beams, and the rectangular frame B of lower ending opening parallel with rectangular frame A is also provided with inside described rectangular frame A, three limits of described rectangular frame B are all curved, and described rectangular frame A and rectangular frame B is connected and fixed by some connection profiles perpendicular to rectangular frame A and rectangular frame B plane.
