Description

Technical Field

[0001] The utility model relates to automobile parts, in particular to a welding assembly of an automobile seat lower frame. Background Art

[0002] The seat lower frame welding assembly is an important component of the commercial vehicle seat structure. As a structural part directly connected to the vehicle body, it is also the main structure to ensure the safety of the driver. Common seat lower frame welding assembly structures are as follows: Figure 1 As shown, the left and right support plates have a complex structure, and the lower support plate is reinforced with corrugated plates. These corrugated plates are stamped parts and therefore expensive to manufacture. With the rapid development of the industry, lightweight and low-cost products are becoming the mainstream development trend for this type of seat lower frame welded assembly, while maintaining basic strength requirements. Therefore, it is necessary to optimize the structure of the existing seat lower frame welded assembly. Utility Model Content

[0003] The utility model aims to provide a welding assembly for a lower frame of an automobile seat.

[0004] The technical solution adopted by the present invention to solve its technical problems is:

[0005] A car seat lower frame welding assembly, comprising:

[0009] The right side support member is installed on the bottom load-bearing frame and is located on the right side of the bottom load-bearing frame. The right side support member and the left side support member support the seat base.

[0010] A lower transition member is mounted on the bottom bearing member and is engaged with the bottom of the left supporting member and the right supporting member, and the lower transition member transitions and reinforces the bottom of the left supporting member and the right supporting member;

[0011] The upper transition component is connected to the top of the left supporting component and the right supporting component, and the upper transition component is used to transition and strengthen the top of the left supporting component and the right supporting component.

[0012] Specifically, the bottom bearing member includes:

[0013] A bottom carrier plate, which is formed by processing a metal plate. A set of connecting openings are provided inside it, and the bottom carrier plate can be installed in the vehicle body through connecting bolts adapted to it;

[0014] A bearing side edge, which is formed at the edge of the bottom carrier plate, extends along the circumference of the bottom carrier plate, and protrudes downward from the bottom carrier plate. An installation space for the bearing reinforcement member is formed by the bearing side edge and the bottom carrier plate.

[0015] The bearing reinforcement member includes:

[0016] Reinforcing square tubes. There is a set of reinforcing square tubes, and each reinforcing square tube is made of a metal pipe fitting. It is welded to the bottom surface of the bottom carrier plate and is parallel to each other. There is a gap between adjacent reinforcing square tubes, and the bottom carrier plate is structurally strengthened by the reinforcing square tubes.

[0017] In an embodiment of the present utility model, the height of the reinforcing square tube is greater than the height of the bearing side edge. When the bottom carrier plate is installed in the vehicle body, the bottom of the reinforcing square tube abuts against the vehicle body. The reinforcing square tube is used instead of the common corrugated plate stamping part, reducing the stamping processing and welding processes, and the production cost is reduced.

[0018] The left support member includes:

[0019] A supporting left plate, which is formed by stamping a metal plate. It is located above the left side of the bottom carrier plate and is arranged vertically;

[0020] A left side surrounding frame, which is formed at the edge of the supporting left plate and is folded inward to the supporting left plate. The left side surrounding frame structurally strengthens the supporting left plate, and its bottom is welded to the top of the bottom carrier plate.

[0021] The right support member includes:

[0022] A supporting right plate, which is formed by stamping a metal plate. It is located above the right side of the bottom carrier plate and is arranged vertically;

[0023] A right side surrounding frame, which is formed at the edge of the supporting right plate and is folded inward to the supporting right plate. The right side surrounding frame structurally strengthens the supporting right plate, and its bottom is welded to the top of the bottom carrier plate.

[0024] The lower transfer member includes:

[0025] A front lower side square tube, which is welded to the top of the bottom carrier plate, and its two ends are respectively joined to the front lower sides of the left side surrounding frame and the right side surrounding frame;

[0026] A rear lower side square tube, which is welded to the top of the bottom carrier plate, and its two ends are respectively joined to the rear lower sides of the left side surrounding frame and the right side surrounding frame.

[0027] The upper transfer member includes:

[0028] A front upper side tube, which is located above the bottom carrier plate, and its two ends are respectively welded to the front upper sides of the left side frame and the right side frame;

[0029] A rear upper side tube, which is located above the bottom carrier plate, and its two ends are respectively welded to the rear upper sides of the left side frame and the right side frame.

[0030] In an embodiment of the present utility model, the thicknesses of the bottom carrier plate, the left support plate, and the right support plate are 2 mm. Changing the material thickness from 2.5 mm to 2 mm can reduce the weight.

[0031] The advantages of the present utility model are as follows:

[0032] Through the mutual cooperation and reinforcement of the bottom bearing member, the bearing reinforcement member, the left and right side support members, and the upper and lower transfer members of the welding assembly of the vehicle seat lower frame, the structural strength and stability of the entire seat lower frame are significantly improved. The reinforcing square tubes, the left side frame, the right side frame, and the square tubes for upper and lower transfer all play an important role in structural reinforcement, enabling the seat lower frame to withstand greater loads and impacts. Using reinforcing square tubes instead of traditional corrugated plate stampings reduces the stamping and welding processes, thereby reducing production costs. By optimizing the use of materials, changing the thicknesses of the bottom carrier plate, the left support plate, and the right support plate from 2.5 mm to 2 mm not only ensures the necessary strength and stiffness but also reduces the overall weight, further reducing material costs.
