Abstract
The utility model provides a body frame structure of a medium passenger car, relating to the field of automobiles. The car body frame structure is a rectangular pentahedron which is formed by the mutual connection of a plurality of horizontal connecting rods, longitudinal connecting rods and slanted connecting rods; the pentahedron consists of a front surface, a rear surface, a left surface, a right surface and a top surface of the car body frame; the connecting rods at the middle part and the middle-lower part of the left surface and the right surface of the car body frame are arranged densely; the right surface of the car body frame is provided with two car door frames formed by the connecting rods; the car door frame comprises a front car door frame and a rear car door frame; and the longitudinal connecting rod positioned at the front of the car body frame is an arc-shaped connecting rod. As the body structure of the large passenger car adopts the mutual connection of the connectingrods by welding, the structure can be produced and manufactured by using small-sized equipment without using grinding tools, and is characterized by short production period, small investment, fast result, capability of reducing the integral cost of the car body frame structure and the like.
Description
Technical field
The utility model relates to automotive field, is specifically related to a kind of car body frame structure of medium bus.
Background technology
The auto body framed structure is the vitals in the automobile, be connected with vehicle chassis below the car body frame structure, evaporator, blower fan, heating installation of car door, glass vehicle window, car light, pneumatic pilot line, electric control circuit, A/C etc. are housed, so the auto body framework is a kind of important foundation part that is used to install various functional components on body shell.In the prior art the auto body framework all by sheet material by compression molding, spot-welded on is generally adopted in connection between the sheet material, this body shell load-carrying capacity, impact resistance is relatively poor, promptly its intensity of body shell and the rigidity of producing with this kind mode is all relatively poor, because the volume of medium-sized or above passenger vehicle is bigger, the length of car body, wide size is all very big, if adopt grinding tool mold pressing body shell parts, employed equipment and grinding tool also can be very huge, if the output of every kind of vehicle is all lower, adopt said method processing body shell, then can cause the very high of body shell cost, even some enterprise just can't realize.In case and body shell occurs just needing integral replacing after impaired, the person also can increase the cost and the maintenance difficulty of automotive servicing, therefore is necessary existing body shell is improved.
The utility model content
The purpose of this utility model is to overcome defective of the prior art, design a kind of car body frame structure of medium bus, this car body frame structure can be manufactured with midget plant, and does not need grinding tool, the little instant effect of investment with short production cycle can reduce the whole cost of the framed structure of vehicle body.
For achieving the above object, the technical solution of the utility model is to adopt a kind of car body frame structure of medium bus, this car body frame structure is by some transverse links, the rectangle pentahedron that longitudinal rod and oblique connecting rod are interconnected to constitute, described pentahedron comprise body shell before, after, a left side, the right side and end face, on a described body shell left side, the described connecting rod dense arrangement in the middle part on the right side and middle and lower part, be provided with two door cases that constitute by connecting rod on the described body shell right side, described door case comprises the preceding doorframe of car, doorframe behind the car, being positioned at body shell fwd longitudinal rod is the arc shaped connecting rod.
Wherein, be connected for circular arc between the connecting rod on the front, rear, left and right face boxed rod of described body shell and the end face.
Wherein, described oblique connecting rod is arranged in the described connecting rod dense arrangement.
Wherein, the joint of described some transverse links, longitudinal rod and oblique connecting rod is in the same place by welding, riveted joint, bolted connection, or has attaching parts to connect.
Wherein, described framed structure leaves the groove that wheel is installed at the left and right side of body shell.
Wherein, be provided with the glass installation frame at the first half periphery of described body shell, the lower part of described body shell is connected with the vehicle body backplate.
Wherein, doorframe is arranged on the forward right side of body shell before the described car, and doorframe is arranged on the middle part of body shell behind the described car.
Advantage of the present utility model and beneficial effect are: because the car body frame structure of this medium bus has adopted the mode of connecting rod welding to interconnect, therefore its available midget plant is manufactured, and do not need grinding tool, this car body frame structure has the little instant effect of investment with short production cycle, can reduce the characteristics such as whole cost of car body frame structure.
