Embodiment Construction

[0057] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0058] like figure 1 , figure 2 As shown, in the frame connection structure of the present invention, the end of the side window lower rail 2 is connected to the column 1 through the middle corner bracket 7, and the side window lower rail 2 is perpendicular to the column 1, and one end of the short waist column 3 passes through the middle corner. The corner code 7 is connected with the middle part of the side window lower rail 2, the other end of the short waist column 3 is connected with the middle part of the side cabin door upper rail 4 through the middle corner code 7, and the short waist column 3 is perpendicular to the side window lower rail 2 And perpendicular to the upper longitudinal beam 4 of the side ha...

Abstract

The invention relates to a connection structure of a vehicle frame. The connection structure of the vehicle frame is located below a vehicle window on the side of a vehicle body frame and above a side cabin door; lower side window longitudinal beams and upper side window longitudinal beams are connected among stand columns; short-waist stand columns are connected between the lower side window longitudinal beams and the upper side window longitudinal beams; the above members are connected through middle corners; inner skins are arranged on sides of the stand columns, the short-waist stand columns, the lower side window longitudinal beams and the upper side cabin door longitudinal beams; reinforcing beams are arranged on the other sides of the inner skins away from the members; and all the members are made of aluminum alloy or magnesium alloy and are connected through rivets. The invention ensures that the intensity of the connection structure of the vehicle frame is not lower than that of the traditional connection structure of the steel vehicle frame, lightens the weight of the vehicle frame and prolongs the service life of the vehicle frame.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a component connection structure used in the frame of a passenger car. Background technique [0002] There are three main types of existing passenger car skeleton structures: [0003] The first type is non-load-bearing. Cars have a rigid frame, also known as a chassis frame. The main body of the vehicle body is suspended on the vehicle frame and connected by elastic elements, mainly relying on the vehicle frame to bear the load, and the vehicle body does not participate in the force bearing. This kind of non-load-bearing body is relatively cumbersome, high in mass, high in the center of mass of the car, and poor in high-speed driving stability. [0004] The second type is semi-loaded. The car with semi-loaded body does not have a rigid frame, but only strengthens the front wall, side wall, rear wall, chassis and other parts. The body and the chassis together form the r...
