Detailed Description
In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.
Example 1, as shown in fig. 1 to 3, the present embodiment is directed to improving the connection strength between a passenger car body stamping part 3 and a floor frame section steel 2, and includes a member body 1, in the present embodiment, the member body 1 includes a fixing part 11 fixedly connected with the floor frame section steel 2 and a stamping part 12 fixedly connected with the passenger car body stamping part 3, and a reinforcing part 13 is further disposed between the fixing part 11 and the stamping part 12, in the present embodiment, the cross section of the fixing part 11 is U-shaped, that is, the fixing part 11 is integrally disposed in a groove shape, and is clamped at the bottom of the section steel, the side edges thereof are in contact with both sides of the section steel, the bottom is combined with the bottom of the section steel, in the present embodiment, carbon dioxide arc welding plug welding is used for fixing, the reinforcing part 13 includes a reinforcing plate 131 connected with the bottom of the fixing part 11 and side plates 132 disposed on, the reinforcing plate 131 is disposed obliquely downward, and the height of the side plate 132 is disposed flush with the fixing portion 11, so that a part of the side plate 132 is also fixed to the section steel by the arc welding. And the stamping part 12 comprises a stamping fixing plate arranged along the outer edge of the reinforcing part 13, and the stamping fixing plate is vertically arranged with the side plate 132.
