Embodiment 1

[0032] In this embodiment, a method for installing a vehicle door sill is provided, including the following steps:

[0033] S1. Provide a sill inner panel 1. The sill inner panel 1 is a steel sheet metal part provided with an upper section 11, a middle section 12 and a lower section 13. The middle section 12 is formed between the upper section 11 and the lower section 13. The middle section 12 and the body floor 3 pass through points Connected by welding to form the skeleton structure of the vehicle body;

[0034] S2. Provide a threshold outer panel 2, the threshold outer panel 2 is installed along the lateral direction of the vehicle, and the top wall 21 of the threshold outer panel 2 is fixedly connected to the upper section 11;

[0035] S3. The side wall 22 of the sill outer panel 2 close to the sill inner panel 1 is fixedly connected with the lower section 13 .

[0036] In the installation method of the vehicle door sill in this embodiment, the steel plate door sill inner...

Embodiment 2

[0043] In this embodiment, continue to refer to figure 2 , provides a vehicle threshold structure, the vehicle threshold structure adopts the installation method of the above-mentioned embodiment to be installed on the vehicle body, including the threshold inner panel 1 and the threshold outer panel 2 of aluminum profiles; the threshold inner panel 1 is a steel sheet metal part, and the threshold inner panel Panel 1 is provided with upper section 11, middle section 12 and lower section 13, middle section 12 is formed between upper section 11 and lower section 13; It is fixedly connected with the side wall 22 of the threshold outer panel 2 close to the threshold inner panel 1 . In the vehicle threshold structure in this embodiment, the threshold inner panel 1 is an integrally formed steel sheet metal part, and the position of the door opening adopts the steel threshold inner panel, which is fixedly connected with the vehicle body floor 3 to form a vehicle body skeleton structu...

Abstract

The invention discloses a vehicle threshold mounting method and a vehicle threshold structure thereof. The mounting method comprises the following steps: providing a threshold inner plate being a steel plate sheet metal part provided with an upper section, a middle section and a lower section, the middle section being formed between the upper section and the lower section, and the middle section being connected with a vehicle body floor in a spot welding mode; forming a vehicle body framework structure; providing a threshold outer plate, installing the threshold outer plate transversely alongthe vehicle, and fixedly connecting the top wall of the threshold outer plate with the upper section; and fixedly connecting the side wall, close to the threshold inner plate, of the threshold outer plate with the lower section. Compared with the prior art, by means of the mode that the threshold inner plate of the steel plate is connected with the threshold outer plate of the aluminum profile andthe spot welding framework of the threshold inner plate and the vehicle body, the precision requirement can be met without other supports or reinforcing pieces, the overall structure is simple, partsdo not need to be polished and adjusted, and the matching performance with peripheral parts is good; and the sealing problem of the seam allowance surface of the vehicle door is effectively solved.

Description

technical field [0001] The invention relates to the technical field of automobile body-in-white, in particular to a vehicle door sill installation method and a vehicle door sill structure. Background technique [0002] The automobile door sill assembly is one of the main connection structures between the side wall and the floor. With the development of the automobile industry, there are more and more new energy vehicles on the market, which require the structure of the body in white to be lighter and stronger. Aluminum profiles are gradually It has entered the field of vision of automobile design, especially in the threshold beam area. Because new energy batteries are installed inside, the threshold position not only needs to meet the driver safety requirements of conventional fuel vehicles, but also needs to protect the battery to meet the safety of the battery in the event of a collision. Requirements, the sill beam structures on the market are all designed with aluminum p...
