Description

Seat heating surface sleeve

Technical Field

The invention belongs to the technical field of vehicle seats, and particularly relates to a seat heating surface sleeve, which is used for improving the comfort of passengers and the internal environment of a cabin by intelligently adjusting the surface temperature of the seat heating surface sleeve.

Background

With the rapid development of the automobile industry and the upgrading of the consumption level of people, people have higher and higher requirements on the comfort of automobiles, particularly for automobile seats, the existing automobile seats generally adopt leather and textile fabrics as surface materials, and materials such as polyurethane foam and the like are filled in the surface materials, so that the comfort of the seats is better. However, in cold weather, passengers are fully aware of the desire for a warm microenvironment in the vehicle cabin. Particularly, in the automobile seat, people often enter the automobile, the first contact is mostly the seat, the first feeling is also seat transmission, if the automobile is cold, passengers enter the automobile, the first feeling is that the passengers are expected to be warm instead of cold, so the seat can be heated in a short time after entering the automobile, and the problem of warming the passengers is a problem which is urgently needed to be solved at present.

Secondly, energy conservation and emission reduction are the work which is highly valued by the whole society at present, and especially the popularization of new energy automobiles, a larger market is developed for green travel. At present, although the air conditioning device of the left-right independent type in the automobile can quickly heat the air in the automobile cabin, the fuel or power consumption is also obvious. Furthermore, the interior of the vehicle is mainly heated by the air conditioner, and body parts not in the flow direction of the hot air may not be heated. In the using process of the air conditioner, firstly, impurities and bacteria on the filter element of the air conditioner are easily blown out to harm the health of passengers and induce respiratory diseases; secondly, the air conditioner can make the car glass cover the vapor in the driving process, has increased driver's danger of driving. Therefore, it is imperative to find a cost-competitive warming solution to improve the comfort of the seat and cabin environment.

Traditional car seat surface intensification mainly relies on the heating pad, and the heating pad is resistance wire, carbon fiber and PTC etc. materials and compound commonly used, and the seat heating pad advantage is that the air conditioner intensifies faster than in the car, and the first sensation of passenger also is that the cushion warms up earlier. But the disadvantages are also very significant, such as:

1) the heating pad is required to be attached to the foam or sewed below the surface sleeve, and the processing technology is increased;

2) the heat quantity is too low, the speed of transferring the heat to the surface of the dough cover is slow, and the energy consumption is high;

3) the installation and arrangement requirements are too high;

4) if the glue is adopted for fixation, the smell and the environmental protection are affected;

5) there is a problem that heat generation is not uniform, heat aggregation is easily generated, and local high temperature is easily generated.

At present, the compounding process of the automobile seat fabric is developing towards the direction of high performance, green and environmental protection. Graphene is used as a heat dissipation carrier, the graphene coating can emit 6-14 μm far infrared rays after being conductively heated through the conductive ink coating, the far infrared rays are used for nursing human bodies, the far infrared rays are close to the vibration frequency of cell molecules in the human bodies, after permeating into the human bodies, the far infrared rays can cause the resonance of atoms and molecules of human cells, the resonance absorption is realized, the vibration friction heat generation thermal reaction is realized between the molecules, the capillary vessel is expanded, the blood circulation is accelerated, the effects of quick body warming and physical therapy are achieved, and high heat can be continuously supplied, which cannot be achieved by the traditional resistance wires, carbon fibers and PTC heating.

A bamboo charcoal fiber layer and a corium layer are sequentially bonded on one side of the flexible netted heat conducting layer from inside to outside, and an aluminum foil layer and a non-woven fabric layer are sequentially bonded on the other side of the flexible metal netted heat conducting layer from inside to outside. The flexible netted heat-conducting layer is woven by the vertically and horizontally woven conductive heating wires, and the problems that the heating wire structure is low in heating efficiency, short in service life, easy to generate convex marks at long-term pressed positions and the like exist.

The graphene heating fabric comprises a heating layer, two insulating layers arranged on two sides of the heating layer, a temperature measuring layer arranged on the outer side of one insulating layer and a covering layer covering the outer side of the temperature measuring layer. Graphene materials can increase the area that generates heat, even heating, advantages such as accurate temperature control, simultaneously, because only describe to the production technology and the flow of raw and other materials in the embodiment, though have ambient temperature and detect, but lack personnel's monitoring, for example the response mechanism that car seat face cover generates heat, car seat has bought the cover rather than having certain difference moreover.

Patent CN109435394A (2019) provides a flexible graphene heating fabric with a real-time temperature monitoring function, which includes a heating temperature measuring layer and insulating layers on two sides. The fabric can be used for heating local parts in a targeted manner, and has the advantages of uniform heating and accurate temperature control. However, as the composite process of the heating fabric adopts bonding to obtain the flexible graphene heating fabric which is more suitable for wearable protective equipment and clothes, the composite process and the application of the heating fabric and the seat cover are not mentioned.

Patent CN106183716B (2020) provides a heating panel for a vehicle that improves the cold problem of the knees of rear passengers by providing heat to the passengers through far infrared radiation. The heating plate installed on the rear surface of the seat back of the vehicle seat is made of a flexible material and has a foldable structure, but is affected by limitation of the curved surface shape of the rear surface of the seat, thus being not beneficial to the overall shape, and the installation process is relatively complicated.
