Abstract
Description
Technical Field
[0001] This application generally relates to the field of vehicle technology, and specifically to a car seat heating pad structure and a car seat. Background Technology
[0002] In the field of heating pads for comfort functions such as car seats, the durability of the heating pad is one of the core indicators for measuring product quality. The key lies in the stability of the bond between the heating wire and the substrate, as well as the heating wire's own resistance to damage. Currently, the mainstream manufacturing processes for heating pads in the industry are mainly divided into two categories: hot pressing and sewing. The hot pressing process involves heat-pressing the heating wire with adhesive particles to the substrate, bonding the two together. This process can, to some extent, fix the position of the heating wire. The sewing process, on the other hand, directly sews the heating wire to the substrate, achieving similar integration.
[0003] However, after the heating pad manufactured using the above process is assembled into the car seat assembly, its grooved area corresponds precisely to the pressure point of the human thigh. During use, this area not only bears significant continuous force, but the seat cover strip also experiences frequent friction with the heating wires. Furthermore, because traditional hot-pressing and sewing processes do not specifically address this critical stress and friction area, the heating wires are often completely fixed in the grooved area, unable to adapt to changes in force and friction. This results in concentrated stress on the heating wires in this area, making them highly susceptible to breakage, wear, and other damage, severely impacting the heating pad's lifespan and safety. Utility Model Content
[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a car seat heating pad structure and car seat that can improve the durability of the heating wire in the groove area and effectively solve the problems of wire breakage, wear and tear.
[0005] In a first aspect, this application provides a car seat heating pad structure, comprising: A substrate, wherein a heating wire is connected to the surface of the substrate; The portion of the heating wire corresponding to the grooved area of the seat is the first heating segment, and the portion of the heating wire corresponding to the non-grooved area of the seat is the second heating segment. The first heating segment is connected to the substrate through a three-point connection, so that the first heating segment can be bent in the grooved area to adapt to the force and friction in the grooved area.
[0006] According to the technical solution provided in this application, the heating wire is connected to the substrate by hot pressing.
[0007] According to the technical solution provided in this application, the outer wall of the first heating section is provided with three uniformly distributed adhesive particles. The adhesive particles are heated and melted by hot pressing to connect the first heating section to the substrate. The outer wall of the second heating section is covered with adhesive particles. The adhesive particles are heated and melted by hot pressing to form an adhesive particle layer in the second heating section and connect it with the substrate.
[0008] According to the technical solution provided in this application, the granules are thermoplastic granules.
[0009] According to the technical solution provided in this application, the heating wire is connected to the substrate by sewing.
[0010] According to the technical solution provided in this application, the two ends and the middle part of the first heating section are connected to the substrate by sewing thread; The second heating section is connected to the substrate by continuous or intermittent sewing along its length using sewing thread.
[0011] According to the technical solution provided in this application, the heating wire includes: The heating wires are multi-stranded and covered with an outer sheath.
[0012] Secondly, this application provides a car seat, including: seat foam, seat cover and the above-mentioned car seat heating pad structure; The seat foam has grooves, the openings of which face the seat cover, and the grooves and the seat cover form the cross-groove area: The car seat heating pad structure is located between the seat foam and the seat cover, and the portion of the car seat heating pad structure corresponding to the cross-groove area contacts the inner wall of the groove.
[0013] As can be seen from the above technical solution, this application has at least the following beneficial effects: This application provides a car seat heating pad structure, including: a substrate, with heating wires connected to the surface of the substrate; the portion of the heating wire corresponding to the groove area of the seat is a first heating segment, and the portion of the heating wire corresponding to the non-groove area of the seat is a second heating segment; the first heating segment is connected to the substrate by a three-point connection, so that the first heating segment can be bent in the groove area, thereby adapting to the force and friction in the groove area.
[0014] This application designates the portion of the heating wire corresponding to the groove-crossing area as the first heating segment. The first heating segment is connected to the substrate using a three-point connection, allowing it to bend freely in the groove-crossing area. This effectively adapts to stress variations in the groove-crossing region, solving the problem of localized stress concentration caused by rigid connections in traditional heating pads at the groove location. Furthermore, the three-point connection of the first heating segment reduces the rigid pulling between the heating wire and the substrate, lowering the risk of breakage or detachment of the heating wire due to repeated friction and effectively extending the service life of the heating pad structure.

[0027] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0029] like Figure 1 and Figure 6 As shown, this application provides a car seat heating pad structure, including: Substrate 1, with heating wire 2 connected to its surface; The portion of the heating wire 2 corresponding to the groove area 3 of the seat is the first heating section 4, and the portion of the heating wire 2 corresponding to the non-groove area of the seat is the second heating section 6. The first heating section 4 is connected to the substrate 1 through a three-point connection, so that the first heating section 4 can be bent at the groove area 3, thereby adapting to the force and friction of the groove area 3.
[0030] The substrate 1 serves as the basic flexible carrier for the entire heating pad structure. It possesses excellent breathability and flexibility, making it suitable for conforming to the complex shapes of seat surfaces. The substrate 1 provides a base plane for the fixing and distribution of the heating wires 2. Here, the substrate 1 can be, for example, non-woven fabric or other flexible, breathable materials.
[0031] Heating wire 2 generates heat by being energized, thus providing heat to the seat. Specifically, as shown... Figure 4 and Figure 9 As shown, the heating wire 2 includes multiple heating wires 9, and the multiple heating wires 9 are covered with an outer sheath 10. The heating wires 9 are used to generate heat when energized, and the outer sheath 10 wraps around the heating wires 9, which serves to insulate and protect the heating wires 9.
[0032] The groove-crossing area 3 refers to the area on the seat surface where grooves exist, such as the area where friction and deformation are most frequent due to the movement of the human thigh during seat use. The non-groove-crossing area refers to the flat area of the seat surface without grooves, where stress and deformation are minimal.
[0033] Based on the positional correspondence between the heating wire 2 and the trench-crossing region 3 and the non-trench-crossing region, the heating wire 2 is divided into a first heating segment 4 and a second heating segment 6. The second heating segment 6 can be connected to the substrate 1 using conventional methods in the art. Since the trench-crossing region 3 requires greater flexibility from the heating wire 2 than the non-trench-crossing region, the connection between the first heating segment 4 and the substrate 1 adopts a three-point connection method. That is, the first heating segment 4 is fixed to the substrate 1 only at three discrete points, such as the two ends and the middle, rather than being continuously and fully covered. This connection method allows the first heating segment 4 of the heating wire 2 to have bendability in the trench-crossing region 3, and can deform according to the force in the trench-crossing region, thereby reducing the tensile stress between it and the substrate 1 and reducing the risk of breakage and detachment.
[0034] like Figure 1 As shown, the heating wire 2 is connected to the substrate 1 by hot pressing. Here, hot pressing refers to the process of applying temperature and pressure to the connection part through heating equipment, so that the connecting material (such as adhesive granules 12) melts and then bonds and fixes the heating wire 2 to the substrate 1.
[0035] Specifically, such as Figure 2 As shown, the outer wall of the first heating section 4 is provided with three evenly distributed rubber particles 12. The rubber particles 12 are heated and melted by hot pressing to connect the first heating section 4 to the substrate 1. Here, the rubber particles 12 at the above three locations are melted by hot pressing to fix the first heating section 4 of the heating wire 2 to the substrate 1, so that the part of the first heating section 4 other than the three fixed points can be bent freely to adapt to the force and friction in the cross-groove area 3.
[0036] like Figure 3 As shown, the outer wall of the second heating section 6 is covered with adhesive granules 12. These granules 12 are heated and melted by hot pressing to form an adhesive particle layer 7 in the second heating section 6, which then connects to the substrate, allowing the heating wire 2 to be fixed to the substrate 1 over a large area. Figure 5 As shown, since the non-cross-groove area is under stable stress and does not require high flexibility, the adhesive particles 12 form a continuous adhesive particle layer 7 in the second heating section 6, which can enhance the connection strength between the heating wire 2 and the substrate 1, prevent the heating wire 2 from shifting, and ensure heating uniformity.
[0037] In addition, the aforementioned granules 12 are, for example, thermoplastic granules.
[0038] Furthermore, such as Figure 6 As shown, the heating wire 2 is connected to the substrate 1 by sewing. Here, sewing means using sewing thread 8 to sew the heating wire 2 to the substrate 1.
[0039] Specifically, such as Figure 7 and Figure 10As shown, the two ends and the middle part of the first heating section 4 are connected to the substrate 1 by sewing thread 8; so that the part of the first heating section 4 except for the three fixed points on it can be bent freely to adapt to the force and friction in the cross-groove area 3.
[0040] like Figure 8 As shown, the second heating section 6 is connected to the substrate 1 by continuous or intermittent sewing along its length using sewing thread 8; by continuous or intermittent sewing along its length using sewing thread 8, relatively dense fixing points are formed, which enhances the connection stability of the non-cross-groove area and prevents the heating thread 2 from loosening.
[0041] This application also provides a car seat, including: seat foam 11, seat cover 5, and the above-mentioned car seat heating pad structure; The seat foam 11 has a groove, the opening of which faces the seat cover 5, and a cross-groove area 3 is formed between the groove and the seat cover 5. The car seat heating pad structure is located between the seat foam 11 and the seat cover 5, and the part of the car seat heating pad structure corresponding to the groove area 3 is in contact with the inner wall of the groove.
[0042] This car seat possesses the functions and advantages of the aforementioned car seat heating pad structure, which will not be elaborated upon here.
[0043] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
