As a device that directly contacts the driver and passengers, the seat plays a pivotal role in the user experience and is also one of the factors that distinguish the level of automobile manufacturers. Conventional seat back panels generally simply lay the fabric single leather flat on the lower mold of the aluminum mold, and then after the mold is completely closed, the polyurethane material is poured and matured to achieve one-piece foaming to make the finished back panel. The back panel and the luminous LOGO cannot be formed in one piece, and the customer's need to add a LOGO of any size and font at any position on the back panel cannot be met. Utility Model Content

[0003] In view of the defects of the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a seat back panel with luminous lines that realizes integrated formation of the back panel and the luminous LOGO and can meet customer needs.

[0004] In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions: an integrated foamed seat back panel with luminous wire, comprising a back panel body and a back panel fabric, and also comprising a luminous wire, the luminous wire is sewn on the back panel fabric, the back panel body and the back panel fabric are integrally foamed, and the back panel fabric is located on the outside of the back panel body, and both ends of the luminous wire pass through the back panel body respectively, leaving wiring heads for connecting with the seat wiring harness.

[0005] Preferably, when the back panel body, back panel fabric and light-emitting wire are foamed in the mold, the back panel fabric is placed at the bottom of the mold, and the terminal ends of the light-emitting wire extend out through the notch of the lower mold frame of the mold and are placed outside the back panel as a whole.

[0006] Preferably, the back panel body is formed by polyurethane foaming and has a Shore hardness of 50 or more.

[0007] Preferably, the overall thickness of the back panel body and the back panel fabric is 3-4 mm.

[0008] Preferably, the back panel fabric is made of PU or PVC.

[0009] Preferably, the sewing shape of the luminous line is a logo pattern.

[0010] The beneficial effects of the utility model are as follows: by sewing the luminous line to the designated area of ​​the back panel fabric, the back panel and the luminous LOGO can be integrated into one, and the needs of customers who want to add a LOGO of any size and font at any position on the back panel can be met. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a schematic diagram of the structure of the seat back panel (with a star-shaped luminous LOGO);

[0012] Figure 2 It is a structural schematic diagram of the lower mold of the mold;

[0013] In the figure: 1-back panel body, 2-back panel fabric, 3-light line, 4-mold lower mold, 4a-notch. DETAILED DESCRIPTION

[0014] In order to better understand the improvements made by the present invention relative to the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0015] like Figure 1 As shown, an integrated foamed seat back with luminous lines is mainly composed of a backboard body 1, a backboard fabric 2 and a luminous line 3. The luminous line 3 is sewn on the backboard fabric 2. The luminous line 3 is sewn in a logo pattern, such as a star pattern. The luminous material in the luminous line 3 is sensitive to the heating temperature. During the casting process, the upper mold and the lower mold 4 need to be controlled differently. The upper mold 5 is required to be kept at 45-65°C, and the lower mold 4 is required to be kept at 40-60°C.

[0016] The back panel body 1 and the back panel fabric 2 are formed by integral foaming, and the back panel fabric 2 is located outside the back panel body 1. When the back panel body 1, the back panel fabric 2 and the light-emitting line 3 are foamed in the mold, the back panel fabric 2 is placed at the bottom of the mold 4. Figure 2 As shown, the terminal ends of the light-emitting wire 3 extend through the notch 4a of the frame of the lower mold 4 and are placed outside the back panel as a whole, so that the two ends of the light-emitting wire 3 pass through the back panel body 1 and leave terminal ends for connecting with the seat wiring harness.

[0017] The back panel body 1 is preferably formed by polyurethane foam with a Shore hardness of more than 50 to meet the hardness requirements of the seat back panel. The material of the back panel fabric 2 is preferably PU or PVC, and the overall thickness of the back panel body 1 and the back panel fabric 2 is 3-4mm to achieve a lightweight seat.

[0018] During the production process, the luminous wire 3 is first sewn on the outer side of the back panel fabric 2 according to the required LOGO pattern, the back panel fabric 2 with the luminous LOGO sewn is fixed on the lower mold 4 of the mold, and then the mold is closed for closed mold casting, and the mold is opened after curing.

[0019] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
