Description

The seating structure that can ventilate and heat

Technical field

The utility model relates to a kind of seat and back cushion, refers to a kind of seating structure of the heating of ventilating especially.

Background technology

At high latitude or cold district, because the weather temperature is a low-temperature condition, cause automotive seat often to present ice-cold situation, feel uncomfortable when this can allow the user just sit,, take down for a long time though automobile has all been matched heating arrangement and improved this situation now, automotive seat still can continue to draw human body temperature, and be easy to generate ice-cold sensation, and hence one can see that, and the heating arrangement of automobile is improved the ice-cold effect of seat and is just seemed limited.

In the existing skill, the heating arrangement that industry is just developed automotive seat improves, this heating arrangement mainly passes through by supplying with external electric energy to its inner set electrothermal piece, by electrothermal piece electric energy is changed into heat energy and has heating effect again, so automotive seat just can improve temperature or keep constant temperature, then the user takes for a long time and does not also have ice-cold sensation.

Yet, existing heating arrangement is for being located among two insulating barriers, this two insulating barrier can be the rubber material, soft insulating materials such as bubble silk floss, the heat conductivity of hence one can see that this two insulating barrier is not good yet, the heats that then is transmitted to the seat cushion top layer is limited, and then cause the efficiency of heating surface of this heating arrangement unclear, though industry adds perforation at this insulating barrier, by improveing permeability of heat by running through of perforation, but when user's weight applies pressure to seat, then perforation is squeezed and can not keeps aperture originally, and therefore, bad still the remaining of the heat conduction of heating arrangement improved.

The specific embodiment

For more understanding the utility model effect, lift following preferred embodiment now and cooperate graphic being described further, wherein:

See also Fig. 1, the utility model can ventilate the heating the seating structure be to be installed in the automotive seat 1, these automotive seat 1 include: a portion 2 of taking for the user and be connected in the back 3 that these 2 ends axially extend up, and it is slightly L-shaped on the whole; And this back 3 is identical with these 2 compositions, does implementation with this one 2 now.

See also Fig. 2, the utility model can ventilate the heating the seating structure include:

One uppermost layer 10 is the surfaces that coat this one 2, is provided with most pores in this uppermost layer 10, and wherein this uppermost layer 10 can adopt corium, pegamoid to mount a layer hole skin, weave cotton cloth and mount layer screen cloth any constitutes.

One endonexine 20, be to be located at the below of this uppermost layer 10 and it pastes an adhesive-bonded fabric 22 by a foam sponge body 21 bottom surfaces gummed, punching and form most pores 211,221 simultaneously again, be all corresponding as shown in Figure 3 with the size and the position of the pore 221 of adhesive-bonded fabric 22 with the pore 211 of this foam sponge body 21, and most pores 211,221 of this endonexine 20 than the pore of this uppermost layer 10 greatly and in correspondence with each other, wherein this endonexine 20 is to sew up with this uppermost layer 10, and this adhesive-bonded fabric 22 can increase the toughness of this endonexine 20 and intercept different sound and up transmits.

One electrothermal layer 30, it is the below of being located at this endonexine 20, pad 31, the one linear electrothermal pieces 33 that this electrothermal layer 30 has a soft materials are installed on this pad 31 and its two ends pick out with an electric wire 35 respectively, and several through holes 37 are formed between the bending of this electrothermal piece 33; Wherein, this electrothermal piece 33 can be heating material groups such as resistance to heat, heating wire and constitutes or make in the printed wire mode, and this electrothermal piece 33 is received external power supplys and sent heat energy by this electric wire 35.

One three-dimensional branching off layer 40, it is the below of being located at this electrothermal layer 30, this three-dimensional branching off layer 40 is provided with most elastic supports 42 by two ventilative 41 of stratum reticulares and is formed, wherein this two air-permeable layer surface is provided with most pores, 42 of this elastic supports by majority independently pillar stiffener constituted, so form airflow channel naturally in 42 of this elastic supports.

One foam sponge body 50 is to be made of foam material, and this foam sponge body 50 is located at these three-dimensional branching off layer 40 belows and is provided with the below that a main air intake 51, one tanks 52 are formed at this main air intake 51.

One support body 60 is the skins that are coated on this foam sponge body 50.

By this, the installation and the description of operation of present embodiment are as follows:

At first; above-mentioned each layer body packed in this one 2 in regular turn; and tank 52 installings one fan 70 in this foam sponge body 50; the one anti-backplate 71 of pressing is installed in this fan 70 tops; the area that should anti-press backplate 71 is greater than the area of these fan 70 end faces and can protect this fan 70 when user's weight presses down; and this fan 70 can agitate air-flow and its skin to be provided with a safety net 73, so can prevent this fan 70 and outside direct contact.

Then, as Fig. 4 and shown in Figure 5, external power supply is connected to the electric wire 35 of this electrothermal layer 30, generate heat after then the electrothermal piece 33 of this electrothermal layer 30 receives electric energy, at this moment, this fan 70 sucks an air-flow, this air-flow enters via the main airway 51 of this foam sponge body 50 and by this three-dimensional branching off layer 40, and absorb the heat energy that this electrothermal piece 33 generates, and then this air-flow forms a heating installation and each through hole 37 by this electrothermal layer 30, at last by this endonexine 20 and uppermost layer 10; By this, this seating structure can be adjusted the temperature of this one 2, improves the ice-cold situation of this one 2 and improves travelling comfort.

Wherein, each pore of this uppermost layer 10, endonexine 20, electrothermal layer 30 and three-dimensional branching off layer 40 or through hole 37 are in correspondence with each other, and form a multiple field flow dividing structure, so the air-flow that this fan 70 sucks is subjected to the shunting guiding of each layer body, and then can scatter equably, therefore, this air-flow can not allow the user not feel well because this air-flow concentrates place output except the heat energy that the electrothermal piece 33 that can absorb this electrothermal layer 30 is all sidedly generated yet.

In addition, when user's weight when the lower compression, this three-dimensional branching off layer 40 can provide the effect of a resilient mounting and can to keep passage smooth and easy, thus smooth and easy when allowing this air-flow up flow, and then make heat conduction efficiency better.

Moreover, except previous embodiment, as shown in Figure 6, it is another preferred embodiment of seating structure that the utility model can ventilate and heat, its with aforementioned different be in: this fan 70A installs in plug-in mode, this fan 70A has the lead main air intake 51A of this seating structure 10A of a guide duct 73A, and is installed in this support body 60A by colluded part 75A by at least two elasticity; By this, can reduce production costs, promote market competition advantage.
