Problems solved by technology

In the prior art, the rear section of the side beam and the front section of the side beam are generally groove-shaped sheet metal parts with a cross-section in the shape of "Ji", and the notches of the rear section of the side beam and the front section of the side beam all face the interior of the car, and the rear section of the side beam The front end of the side beam and the rear end of the front section of the side beam are directly superimposed and overlapped together. The position of the large assembly needs to be adjusted many times when the vehicle door sill side beam of this structure is finally hoisted and welded. The rear section of the side beam and the side beam The front section cannot be spliced ​​together in the up and down direction, making assembly difficult

Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] Such as Figure 1 to Figure 6 A vehicle door sill side beam shown includes a U-shaped beam rear section 1 and a front section 2 of the side beam, the rear section 1 of the side beam and the front section 2 of the side beam are sheet metal parts, and the rear section 1 of the side beam It includes a first bottom wall 3 extending in the front-rear direction, a first upper side wall 4 extending leftward from the upper edge of the first bottom wall 3 , and a first lower side wall extending leftward from the lower edge of the first bottom wall 3 5. The front end of the upper half of the first bottom wall 3 is a first overlapping portion 6 protruding forward from the front end of the lower half of the first bottom wall 3, and the first overlapping portion 6 is directed from bottom to top. Tilting to the left, the front end of the lower half of the first bottom wall 3 is a...

Abstract

The invention relates to an automobile door sill side beam which comprises a side beam rear section and a side beam front section, wherein the side beam rear section comprises a first bottom wall, a first upper side wall and a first lower side wall; the front end part of the upper half of the first bottom wall is a first overlapping-connection section which protrudes forwardly from the front end part of the lower half of the first bottom wall; the front end part of the lower half of the first bottom wall is a second overlapping-connection section; the side beam front section comprises a secondbottom wall, a second upper side wall and a second lower side wall; the rear end part of the upper half of the second bottom wall is a fifth overlapping-connection section; the rear end part of the lower half of the second bottom wall is a sixth overlapping-connection section which protrudes backwardly from the rear end part of the upper half of the second bottom wall; the first overlapping-connection section and the fifth overlapping-connection section are overlapped and connected; the first overlapping-connection section is positioned on the right side of the fifth overlapping-connection section; the second overlapping-connection section and the sixth overlapping-connection section are overlapped and connected; and the second overlapping-connection section is positioned on the left sideof the sixth overlapping-connection section. The automobile door sill side beam is capable of reducing the assembly difficulty, improving the stability of the overlapping connection, and reducing theoccurrence of dripping of welding sealant.

Description

technical field [0001] The invention relates to auto parts, in particular to an automobile door sill side beam. Background technique [0002] In order to reduce the upper part process and simplify the process flow, the upper part of the large assembly is generally used at present, and the threshold area is an important overlapping area between the large assemblies. Its structural form determines whether it meets the operability and threshold of the welding process. The tightness of the inner space. Segmented car door sill side beams include the rear section of the side beam and the front section of the side beam. The rear section of the side beam and the front section of the side beam are respectively welded on two large assemblies. During the assembly process, the two large assemblies are hoisted and welded. Then weld the rear section of the side beam and the front section of the side beam into one body. In the prior art, the rear section of the side beam and the front se...
