Description

Technical Field

[0001] This application generally relates to the field of automotive technology, and specifically to an assembly structure for an automotive seat heating pad. Background Technology

[0002] With the continuous development of technology in the field of vehicle transportation, people's requirements for vehicle ride comfort are increasing, and many seats are equipped with features such as massage, ventilation, and heating. In order to prevent the seat heating pad from falling off or shifting during use and causing heat accumulation problems, the market usually uses adhesive (using double-sided tape to fix the seat heating pad to the seat foam) and sewing (first sewing the seat heating pad to the cover, and then assembling it onto the seat) as fixing methods.

[0003] Currently, in existing technologies, when heating functions are jointly developed and designed with lumbar support and massage, the heating pad is usually fixed using a multi-point sewing area. However, this technology has significant drawbacks: it wastes the sewing time of seat manufacturers and increases assembly costs. Furthermore, because seat manufacturers need to consider both the aesthetics and comfort of the seat structure, the seat's structural features (such as suspension or other shaped grooves) often lack sewing areas. Without sewing, the heating pad will fold under heating conditions, leading to heat accumulation. When heating and ventilation are jointly developed and designed, the market typically uses double-sided adhesive to attach the heating pad to the foam, but some substrates can generate noise during actual use.

[0017] 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 relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0018] 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.

[0019] Example 1 Please refer to Figures 1-3This application provides an assembly structure for a car seat heating pad, wherein the car seat has a bearing surface for supporting a human body, comprising: The seat body includes a foam structure 1 and a seat cover 2. The seat cover 2 is located on the side of the foam structure 1 near the bearing surface and is fixedly connected to the foam structure 1. Multiple snap-fit ​​holes 3 are provided through the foam structure 1. Heating pad 4 is disposed between seat cover 2 and foam structure 1; The fixing structure has multiple corresponding snap-fit ​​holes 3. The fixing structure is connected to the heating pad 4 and / or the seat cover 2. The fixing structure passes through the corresponding snap-fit ​​hole 3 and snaps into the foam structure 1 to fix the heating pad 4.

[0020] In this embodiment, the seat cover 2 serves as the surface layer that comes into direct contact with the driver and passengers, providing a comfortable feel and an aesthetically pleasing appearance; the heating pad 4 is an electrothermal component that raises the surface temperature of the seat by generating heat, thereby improving seating comfort; and the foam structure 1 is shaped according to ergonomic principles, providing stable support and a reasonable pressure distribution for the occupant. Working principle: This application utilizes multiple snap-fit ​​holes 3 drilled through the foam structure 1, and a fixing structure passes through the corresponding snap-fit ​​holes 3 to snap-fit ​​and fix it to the foam structure 1. The fixing structure is connected to the heating pad 4 and / or the seat cover 2. This fixing method eliminates the need for traditional double-sided adhesive or multi-point sewing, avoiding the noise and odor problems that may be caused by double-sided adhesive, and solving the drawbacks of multi-point sewing, such as wasted labor time, increased assembly costs, and the heat accumulation caused by the heating pad 4 folding due to the limited sewing area caused by the seat shape structure. At the same time, the snap-fit ​​fixing method is simple to operate and can ensure that the heating pad 4 is stably placed between the seat cover 2 and the foam structure 1, effectively preventing it from falling off or shifting during use. It takes into account both the aesthetics of the seat structure and the riding comfort, bringing a better riding experience to the user.

[0021] In some embodiments, the fixing structure is connected to the heating pad 4 via a first base fabric 61.

[0022] In this embodiment, as Figure 1 and Figure 2As shown, the first base fabric 61 is a flexible material. One end of the first base fabric 61 is connected to the heating pad 4, and the other end is connected to the fixed structure. This design effectively absorbs the stress and deformation generated during seat use through flexible connection, avoiding localized wear or abnormal noise that may be caused by rigid connection. The selection of the base fabric material ensures connection strength while also taking into account the requirements of lightweight and low odor, making it particularly suitable for passenger vehicle environments with strict control over noise and volatile organic compounds. This embodiment provides a stable and durable intermediate connection solution, significantly reducing the risk of the heating pad 4 loosening or shifting under long-term vibration and temperature changes, and improving the overall reliability and service life of the system.

[0023] In some embodiments, the fixing structure is a first clip 5, which is connected to the first base fabric 61, and the first clip 5 passes through the corresponding snap-fit ​​hole 3 and is snap-fitted and fixed to the foam structure 1.

[0024] Specifically, the fixing structure can use a plastic clip 5, which is firmly connected to the first base fabric 61 and passes through the corresponding snap-fit ​​hole 3 in the foam structure 1, ultimately forming a snap-fit ​​fixation with the foam structure 1. This snap-fit ​​method eliminates the traditional sewing or gluing process, which not only effectively avoids the noise that may be caused by the aging of adhesive materials, but also significantly reduces the labor time and cost consumption caused by sewing. At the same time, the mechanical snap-fit ​​ensures that the heating pad 4 can remain flat and stable under various usage conditions, which is especially suitable for composite seat structures with multi-functional configurations such as ventilation and massage. While simplifying the assembly process, it improves the overall reliability and comfort of the product.

[0025] In some embodiments, the first base fabric 61 is respectively disposed on the edge of the heating pad 4 and / or on the heating area of ​​the heating pad 4; the snap-fit ​​hole 3 corresponds to the position of the first base fabric 61.

[0026] Specifically, the first base fabric 61 is respectively disposed on the outer edge of the heating pad 4 and on the heating area; wherein, the heating area refers to the area on the heating pad 4 where heating wires are arranged, and the first base fabric 61 is precisely arranged to avoid the heating wires in this area; in this embodiment, the heating area is located in the middle of the heating pad 4; at the same time, the snap-fit ​​holes 3 on the foam structure 1 also correspond to the position of the first base fabric 61. This arrangement enables the heating pad 4 to obtain uniform and reliable fixing force in multiple key parts, effectively avoiding wrinkling, displacement or folding caused by local stress concentration or insufficient fixing points during long-term use. Especially when the seat cover 2 has complex structures such as suspension or shaping grooves, this fixing strategy targeting the edge and middle of the heating pad 4 can better adapt to the deformation requirements of different areas, while maintaining the flatness of the heating pad 4 surface, preventing connection failure due to frequent pressure or vibration, and further improving the working stability and service life of the heating pad 4.

[0027] In some embodiments, the first base fabric 61 and the heating pad 4 are integrally molded structures.

[0028] Specifically, such as Figure 3 As shown, the first base fabric 61 and the heating pad 4 adopt an integral molding structure, that is, the first base fabric 61 is directly extended from the heating pad 4 substrate through cutting, molding or other processing methods. This structure eliminates additional connectors or sewing steps, which not only simplifies the production process and reduces the number of parts and assembly costs, but also avoids abnormal noise or reliability problems caused by the detachment or aging of additional connectors. The integrally molded first base fabric 61 ensures the mechanical connection strength while ensuring the integrity and surface flatness of the heating pad 4, which is especially suitable for seating areas with limited space or high comfort requirements. This design further improves the structural durability and operational stability of the heating pad 4 under long-term vibration and temperature cycling.

[0029] In some embodiments, a groove 9 is provided on the side of the foam structure 1 near the seat cover 2, and a seat soft layer 10 is provided in the groove 9. A heating pad 4 is provided on the side of the seat soft layer 10 near the seat cover 2. A second through hole 11 is provided on the seat soft layer 10 corresponding to the fixing structure. The fixing structure passes through the second through hole 11 and the snap-fit ​​hole 3 in sequence and snaps and fixes itself to the foam structure 1.

[0030] Specifically, a groove 9 is provided on the side of the foam structure 1 near the seat cover 2, and a seat soft layer 10 is provided in the groove 9 to further improve the comfort and support uniformity. The heating pad 4 is placed on the seat soft layer 10 and below the seat cover 2, so as to provide heating function while maintaining the soft touch of the seat surface. Corresponding to the position of the fixing structure, the seat soft layer 10 also has a second through hole 11, so that the fixing structure can pass through the second through hole 11 and the snap-fit ​​hole 3 on the foam structure 1 in sequence, and finally achieve a stable snap-fit ​​with the foam structure 1. This layout not only realizes the reliable fixing of the heating pad 4, effectively preventing it from shifting or wrinkling during long-term use, but also reduces stress concentration through the cushioning effect of the seat soft layer 10, avoiding discomfort or abnormal noise caused by local pressure. It is especially suitable for high-end seat configurations that integrate ventilation, massage and other functions, and can maintain the integrity and comfort of the structure under complex use conditions.

[0031] Example 2 Please refer to Figures 4-9 The present application provides an assembly structure for a car seat heating pad. The similarities between this embodiment and Embodiment 1 will not be repeated here, but the differences are as follows: The fixing structure is set on the side of the seat cover 2 near the foam structure 1. The heating pad 4 is provided with a first through hole 62 corresponding to the fixing structure. The fixing structure passes through the first through hole 62 and the snap-fit ​​hole 3 in sequence and is snap-fitted to the foam structure 1.

[0032] Specifically, such as Figures 4-9 As shown, the fixing structure is located on the side of the seat cover 2 near the foam structure 1. The heating pad 4 has a first through hole 62 corresponding to the fixing structure. The fixing structure can pass through the first through hole 62 and the corresponding snap-fit ​​hole 3 on the foam structure 1 in sequence, and finally form a snap-fit ​​fixation with the foam structure 1. This application makes full use of the original structure of the seat cover 2 to realize the positioning and installation of the heating pad 4 without adding any additional parts to the heating pad 4, which simplifies the structural complexity of the heating pad 4 body. At the same time, the cooperation between the first through hole 62 and the snap-fit ​​hole 3 realizes precise alignment and mechanical interlocking, effectively restricting the movement of the heating pad 4 in all directions, avoiding misalignment and wrinkles caused by long-term use or temperature changes, improving the working stability and service life of the heating pad 4, and is especially suitable for application scenarios with high requirements for the shape integrity of the seat cover 2.

[0033] In some embodiments, the fixing structure is a second base fabric 7 and a second clip 8, with one end of the second base fabric 7 connected to the seat cover 2 and the other end connected to the second clip 8.

[0034] Specifically, such as Figure 9 As shown, the fixing structure consists of a second base fabric 7 and a second locking strip 8. One end of the second base fabric 7 is connected to the seat cover 2, and the other end is connected to the locking strip. In this embodiment, the fixing components are pre-set on the seat cover 2 without any modification to the heating pad 4, thereby simplifying the structure of the heating pad 4 and maintaining its versatility. Through the flexible connection of the second base fabric 7, the second locking strip 8 can adaptively align and pass through the corresponding holes on the heating pad 4 and the foam structure 1, ultimately achieving a snap-fit ​​fixation with the foam structure 1. This design not only makes full use of the existing structure of the seat cover 2, reducing the overall complexity of the system and the number of parts, but also enhances the flexibility and fault tolerance during the assembly process, while ensuring that the heating pad 4 remains flat and stable during long-term use, making it particularly suitable for applications that require frequent disassembly or maintenance.

[0035] In some embodiments, the first through hole 62 is respectively provided on the edge of the heating pad 4 and / or on the heating area of ​​the heating pad 4; the snap-fit ​​hole 3 corresponds to the position of the first through hole 62.

[0036] Specifically, the first through-hole 62 is respectively set on the edge area and the heating zone of the heating pad 4; wherein, the heating zone refers to the area on the heating pad 4 where heating wires are arranged, and the first through-hole 62 is precisely arranged in this area to avoid the arrangement of heating wires; in this embodiment, the heating zone is set in the middle of the heating pad 4; at the same time, the snap-fit ​​hole 3 on the foam structure 1 also corresponds to the position of the first through-hole 62. This arrangement enables the heating pad 4 to be uniformly and reliably fixed in multiple key stress areas such as the edge and the middle, effectively dispersing local stress and avoiding wrinkling, displacement or folding caused by insufficient fixation during long-term use. Especially when the seat cover 2 has complex structures such as suspension or shaping grooves, this multi-point fixing strategy can better adapt to the deformation characteristics of different areas, while maintaining the flatness of the heating pad 4 surface, enhancing its vibration resistance and fatigue resistance, thereby comprehensively improving the working stability and service life of the heating pad 4.

[0037] In some embodiments, a plurality of staple grooves 12 are provided on the central axis of the heating pad 4, and a first through hole 62 is provided between two adjacent staple grooves 12.

[0038] Specifically, multiple staple slots 12 are provided on the central axis of the heating pad 4, and the first through holes 62 located on the central axis are respectively set between two adjacent staple slots 12. This layout design realizes the optimized allocation of functional areas on the heating pad 4. The staple slots 12 can be used to assist in positioning or fixing additional components such as heating wire harnesses, while the reasonable arrangement of the first through holes 62 avoids functional interference with the staple slots 12. By setting the first through holes 62 and staple slots 12 at intervals on the central axis, it is ensured that the heating pad 4 obtains uniform and reliable fixing force at multiple points, effectively preventing collapse or wrinkling in the middle area due to insufficient support, and ensuring the safety and neatness of electrical connections. This compact and orderly design is particularly suitable for high-end seating platforms that integrate multiple comfort functions, achieving a unity of structural stability and functional integrity in a limited space, while providing convenience for standardized installation on the production line.
