Description

Technical Field

[0001] The invention relates to a seat backboard manufacturing process, and in particular to a roller-pressed seat backboard frame structure and a manufacturing method thereof. Background Art

[0002] The seat back panel is part of the seat back support frame, and a rectangular tubular support frame is usually arranged around the back panel to ensure the support performance of the seat.

[0003] The back panel is generally a plastic plate or a metal plate, and is mainly formed by a mold. In the existing manufacturing process, different molds need to be developed for the back panels of different models due to the different sizes of the back panels, and the manufacturing cost has always been high.

[0004] At the same time, the existing back panel is preset with a flange structure for hanging the face cover. Due to the limitation of this factor, it is difficult to use other manufacturing processes to replace the existing molding process for the back panel when solving the problem of high manufacturing cost. Summary of the Invention

[0005] In view of this, the present invention provides a roller-pressed seat back panel frame structure, which can use the same roller-pressing equipment to manufacture back panels of different sizes, thereby solving the technical problem of high cost of traditional back panel manufacturing processes.

[0006] To achieve the above purpose, the technical solution of the present invention is as follows:

[0007] A roller-pressed seat backboard frame structure comprises a backboard body, a support tube is provided on the circumferential edge of the backboard body, and a flange structure for hanging a face cover is provided on the outer side of the support tube.

[0008] By adopting the above structure, the flange structure of the original car seat back panel used for hanging the cover is integrated into the outer support tube, thereby reducing the processing steps and overall manufacturing difficulty of the back panel. The back panel body has a plate structure and can be formed by a process such as roll pressing and then connected to the support tube as a whole, making the back panel design more flexible and compatible with more car models, reducing the investment in molds and equipment when producing back panels of different car models.

[0009] Preferably, the back panel is a rectangular plate, and the support tubes are provided in four sets, each welded to the four side edges of the back panel. With this structure, when the back panel is formed using a roller pressing process, the roller width can be adjusted to adapt the back panel to different vehicle models, thereby reducing manufacturing costs.

[0010] Preferably, the ends of the support tubes are each provided with an inclined surface, and the ends of two adjacent support tubes are welded together via the inclined surface. The above structure is adopted to facilitate rapid welding and installation.

[0011] Preferably, the backboard body is a rectangular plate, and the support tubes are provided in four sets, with two opposing sets of support tubes integrally roll-formed with the backboard body, and two other opposing sets of support tubes welded to the side edges of the backboard body. With this structure, the spacing between the two sets of support tubes integrally formed with the backboard body can also be adjusted by adjusting the rolling width of the rolling equipment.

[0012] The present invention also provides a method for manufacturing a seat backboard frame structure, which includes first using a rolling process to form the backboard body, then using a rolling process to integrally form the support tube and the flanging structure, and finally connecting the support tube to the edge of the backboard body.

[0013] By adopting the above method, the back panel can be made suitable for different car models by adjusting the rolling width of the rolling equipment, which solves the technical problem that the traditional molding process requires the development of different molds.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By transferring the back panel's circumferential flange structure to the support tube, the back panel can be formed using a roll-forming process, and then the support tube can be welded to the back panel. The roll-forming process allows the back panel to be tailored to different vehicle models by adjusting the roll width of the roll-forming equipment, thus resolving the high cost associated with developing different molds for traditional molding processes.

[0017] Figure 2 This is a schematic diagram of the exploded structure of the backplane frame structure embodiment 1;

[0020] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0021] Example 1

[0022] like Figure 1 and 2The structure shown is a roll-formed seat back frame structure consisting of a back panel body 1 and four sets of support tubes 2. The back panel body 1 is a rectangular plate, and the outer sides of the four sets of support tubes 2 are each equipped with a U-shaped flange structure 2a for attaching a seat cover. Two opposing sets of support tubes 2 are roll-formed integrally with the back panel body 1, while the other two opposing sets of support tubes 2 are welded to the side edges of the back panel body 1.

[0023] Furthermore, to ensure the strength of the skeleton and facilitate installation, the four groups of support tubes 2 are all rectangular square tubes, and the cross-sections of the two rectangular square tubes integrally roll-formed with the backboard body 1 have two layers of rectangular holes 2c.

[0024] The manufacturing method of the above-mentioned seat back panel frame structure is: first, use a rolling process to integrally form the back panel body 1 and the support tubes 2 and flange structures 2a at its left and right ends, then use a rolling process or other process to separately form the other two support tubes 2 and the flange structures 2a thereon, and finally weld the separately formed support tubes 2 to the front and rear ends of the back panel body 1.

[0025] When the backboard body 1 and the support tubes 2 at its left and right ends are integrally formed by a rolling process, backboards with different widths can be manufactured by adjusting the rolling width of the rolling equipment.

[0026] Example 2

[0027] like Figure 3 and 4 The figure shows a roll-formed seat back frame structure consisting of a back panel body 1 and four sets of support tubes 2. The back panel body 1 is a rectangular plate, and the outer sides of the four sets of support tubes 2 are each provided with a U-shaped flange structure 2a for attaching the seat cover. The four sets of support tubes 2 are all rectangular square tubes and are connected to the four side edges of the back panel body 1 by welding.

[0028] The above-described seat back frame structure is manufactured by first forming the back panel body 1 using a roll-forming process, then forming four support tubes 2 and the flange structures 2a thereon using a roll-forming process or other process, and finally welding the four support tubes 2 to the circumferential edges of the back panel body 1. When forming the back panel body 1 using a roll-forming process, back panels of varying widths can be manufactured by adjusting the roll-forming width of the roll-forming equipment.

[0029] Furthermore, in the prior art, after the support tube 2 is assembled and connected to the back panel body 1, a component that can press the end of the support tube 2 needs to be installed at the place where the adjacent support tubes 2 are connected. The assembly process is relatively cumbersome. For this reason, the end of the support tube 2 can be designed as an inclined surface 2b, and the ends of the two adjacent support tubes 2 are welded together through the inclined surface 2b to achieve the purpose of simplifying the assembly process.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
