Embodiment Construction

[0030] Hereinafter, one embodiment of the joining structure of the present invention will be described with reference to the drawings. The joining structure of the present invention includes two members (a first member and a second member), and the longitudinal end of the second member is joined to the side portion of the first member in the longitudinal direction to form a T-shape. In this embodiment, an example in which the cross member 20 constituting the frame of the vehicle body is connected to the side member 10 , that is, an example in which the first member is the side member 10 and the second member is the cross member 20 will be described.

[0031] use Figure 1 to Figure 5 , and this embodiment will be described. Such as figure 1 As shown, the side members 10 of this embodiment are members constituting the vehicle body frame and extend in the vehicle front-rear direction, and the side members 10 are members arranged in pairs on both sides in the vehicle width dir...

Abstract

The invention provides a connecting structure which can improve the rigidity of a bending load acting on a T-shaped connecting part. In a connecting structure, a second part 20 is connected to a first part 10 to form a T-shape, wherein a first upper surface 11a and a flange 25 are connected together through the connecting parts 30a, 30b. First curved ribs 15a, 16a are arranged on the rear of the first upper surface 11a, separated and removed from the second part 20 with corners 22b, 23b as starting points, and then flex in a first direction and extend in the first direction. second curved ribs 15b, 16b and the first curved ribs 15a, 16a and are opposite. The first curved ribs 15a and 16a and the second curved ribs 15b, 16b cross each other at two points and define enclosed areas 15c, 16c. ; The enclosed areas 15c, 16c overlap with the connecting area of the connecting parts 30a, 30b.

Description

technical field [0001] The present invention relates to a joining structure in which two members formed of fiber-reinforced resin materials are joined in a T-shape. Background technique [0002] As a structure for joining members constituting the framework of the vehicle body, there is a joining structure in which members intersect in a T-shape. For example, the joint between the side beam and the cross beam has a T-shaped joint structure. The side member is a member extending in the vehicle front-rear direction, and the cross member is a member extending in the vehicle width direction. Since a joint between these members is subjected to a bending load or a torsional load, the joint is sometimes reinforced with a reinforcing member or the like. It is required for such a reinforcing member to be able to increase strength and also to be able to disperse stress. As for the joint between these members, for example, as disclosed in Patent Document 1, there is known a technique...
