Description

Technical Field

[0001] This utility model belongs to the field of automotive seat ventilation technology, and particularly relates to a seat ventilation and heating device, an automotive seat, and an automotive. Background Technology

[0002] Car seats can be categorized by shape (split seats, bench seats); by function (fixed, removable, adjustable); and by seating capacity (single, double, multi-seat). Based on performance, seats have evolved from early fixed seats to multi-functional power-adjustable seats, including air-cushioned seats, electric seats, stereo seats, recovery seats, and finally electronically adjustable seats. They can also be categorized by material (leather seats, cloth seats, etc.). There are also seats for special purposes, such as child seats and racing seats. Car seat cushions are a major consumer product for car owners. Choosing a comfortable and practical car seat cushion is especially important depending on the season.

[0003] Currently, existing car seats can be equipped with heating functions, but their heating mechanisms are mainly conducted through heating pads placed on the A-side of the seat (the surface in contact with the passenger). Due to the limitations of the seat shape, the heating pads cannot cover the entire passenger contact surface of the seat. In addition, since the heating pads are placed on the A-side, there are inherent safety risks caused by passenger knee pressure, buttocks, and massage movements. Utility Model Content

[0023] The present invention provides a seat ventilation and heating device in further detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description.

[0024] Example 1

[0025] See Figure 1-2 A seat ventilation and heating device includes: an air bag 1, a fan 3, a heating pad 2, and a heating module.

[0026] The air bag 1 is installed on the backrest and / or seat cushion of the seat. The air bag 1 exhausts air to the seat surface. The air bag 1 has a first surface and a second surface. The first surface is the surface close to the seat A surface (the seat A surface is the surface that contacts the passenger). The second surface is the surface away from the seat A surface. The first surface and the second surface each have a plurality of first air outlets.

[0027] The fan 3 is installed in the seat and connected to the air bag 1 to provide airflow to the air bag 1;

[0028] The heating pad 2 is fixed to the first surface and / or the second surface of the air bag 1. The heating pad is electrically connected to the heating module. An NTC thermistor is installed inside the heating pad and is electrically connected to the heating module.

[0029] The heating pad 2 can be attached to the first surface of the air bag 1, or to the second surface of the air bag 1, or both. With the heating pad 2 fixed to both surfaces of the air bag 1, it is heated by the heating module. Because the heating pad 2 is fixed to the surface of the air bag 1, when the air bag 1 discharges air to the user, it can also deliver hot air to the user. The heating module can control the temperature of the air blown out by the air bag 1 using an NTC thermistor (calibrated according to customer needs), thereby fully transferring hot air of different temperatures to the seat surface and improving user comfort.

[0030] The surface area of ​​heating pad 2 can be larger than the area of ​​the first or second surface of air bag 1 (e.g.) Figure 1 It can also be smaller than the area of ​​the first or second surface of the air bag 1, or the same as the area of ​​the first or second surface of the air bag 1 (e.g., Figure 2 (This is not restricted.)

[0031] To increase the ventilation of the heating pad 2, the heating pad 2 is provided with multiple second air outlets 4, so that the air discharged from the air bag 1 is discharged from the heating pad 2, and the first air outlet and the second air outlet 4 are connected.

[0032] In some embodiments, the air bag 1 is glued and fixed to the back of the seat foam, or the air bag 1 is glued and fixed to the front of the seat foam. The seat foam is provided with a third air outlet communicating with the first air outlet on the air bag 1. The structure is simple and easy to install. Preferably, taking into account the heating pad 2, the air bag 1 is glued and fixed to the front of the seat foam.

[0033] Furthermore, the back or front of the seat foam is provided with a mounting compartment for embedding the air bag 1, which saves installation space and facilitates installation. Here, the front of the seat foam is the side closest to the user, and the back of the seat foam is the side away from the user.

[0034] In some embodiments, the seat ventilation and heating device further includes a ventilation duct 7, one end of which is connected to a fan 3 and the other end to the air bag 1, so that the fan 3 can be installed on the back of the car seat and the air can be delivered to the air bag 1 through the ventilation duct 7.

[0035] In some embodiments, the air bag 1 has a cavity 5 containing a plurality of reinforcing columns 6; or in another embodiment, the air bag 1 is 3D ventilated memory foam.

[0036] The ventilation and heating device in this embodiment has a heating pad 2 that fits the seat, which is suitable for different types of vehicle seats, improves the comfort of use, and fully meets the user's needs. It uses a fan 3 to blow air and spreads the airflow evenly through the air bag 1. After the heating pad 2 is heated by electricity, it can ventilate and heat the car seat cushion and backrest, thereby fully transferring air of different temperatures to the seat surface.
