Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a seat heating pad mechanism that is resistant to stretching and compression for use in automotive massage seats. Background Technology

[0002] Seat heating, as an important component of car seats, primarily enhances passenger comfort. With continuous technological advancements, most high-end car models now offer massage and seat heating features. However, current models have flaws in the placement of these features, leading to heating failures and a feeling of foreign objects during massage. Furthermore, the heating layer in the massage area frequently suffers damage due to friction. Utility Model Content

[0003] In view of the above problems, the purpose of this utility model is to provide a seat heating pad mechanism that is resistant to stretching and compression for use in car massage seats, so as to improve the wear resistance and compression resistance of the heating pad mechanism and fundamentally overcome the shortcomings of the prior art.

[0004] This utility model provides a tensile and compressive resistant seat heating pad mechanism suitable for car massage seats, comprising: a seat, a massage mechanism installed on the seat, and a heating mechanism. The heating mechanism on the seat is located above the massage mechanism. The improvement is that the heating mechanism includes: a bottom substrate, an electrode layer, a heating layer, and a top substrate arranged sequentially from bottom to top. The bottom substrate and the top substrate are fixed by thermal bonding or adhesive connection. The electrode layer is printed with copper foil or silver paste and is set on the bottom surface of the heating layer. The heating layer uses a heating element and a TPU (thermoplastic polyurethane elastomer) substrate covering the heating element. The bottom substrate and the top substrate are made of wear-resistant and waterproof fabric. The electrode layer is connected to a power source through leads. When the electrode layer is energized, it supplies power to the heating element, causing the heating element to generate heat.

[0005] As a preferred embodiment of this invention, the electrode layer is arranged on both sides of the heating layer, avoiding the massage head position of the massage mechanism, to prevent heating failure and foreign body sensation caused by massage.

[0006] As a preferred embodiment of this invention, the heating element is one of resistance wire, carbon fiber, or graphene heating film.

[0007] As a preferred embodiment of this invention, the heating mechanism is provided with a separate NTC thermistor sensing area. The heating power of the NTC thermistor sensing area is the same as that of the heating area of ​​the heating mechanism. The NTC thermistor in the NTC thermistor sensing area is used for temperature detection feedback.

[0008] The beneficial effects of this utility model are as follows:

[0009] 1. The bottom substrate and the top substrate of this utility model are thermally bonded or glued together, which protects and waterproofs the key heating layer and electrode layer.

[0010] 2. The heating layer of this utility model uses TPU substrate to cover the heating element, ensuring wear resistance and extrusion resistance.

[0011] 3. This utility model uses a lead wire structure at the slot and power connection to ensure connection strength and stability.

[0012] 4. The NTC thermistor of this utility model is arranged in a separate NTC sensing area, and its heating power is the same as that of other heating areas, so as to realize temperature detection feedback.

[0013] 5. The electrode layer of this utility model is arranged on both sides of the massage area, avoiding the movement space of the massage head, to ensure the stability of the electrode. Attached Figure Description

The electrode layer 3 is printed with copper foil or silver paste and is set on the bottom surface of the heating layer 4. The heating layer 4 uses a heating element and a TPU (thermoplastic polyurethane elastomer) substrate covering the heating element. The bottom substrate 2 and the top substrate 5 are made of wear-resistant and waterproof fabric. The electrode layer 3 is connected to a power source through a lead wire 7. After the electrode layer 3 is energized, it supplies power to the heating element, causing the heating element to generate heat.
