Ventilated and heated seating structure

technical field

The utility model relates to a seat cushion, in particular to a ventilated and heated seat structure.

Background technique

In high latitudes or cold regions, due to the low temperature of the weather, the car seats are often icy, which will make the user feel uncomfortable when sitting, although today's cars are equipped with heating equipment to improve this situation , but under long-term riding, the car seat will continue to absorb the temperature of the human body, and it is easy to produce a cold feeling. It can be seen that the effect of the car's heating equipment on improving the coldness of the seat is limited.

In the existing technology, the industry has developed a car seat heating device to improve it. The heating device mainly supplies external electric energy to the electric heating element installed inside it, and then the electric heating element converts the electric energy into heat energy to have a heating effect. , so the car seat can increase the temperature or maintain a constant temperature, and the user will not feel cold when riding for a long time.

However, the existing heating device is sandwiched between two insulating layers, and the two insulating layers can be made of soft insulating materials such as rubber and foam, so it can be seen that the thermal conductivity of the two insulating layers is not good. The heating effect conducted to the surface of the seat cushion is limited, resulting in poor heating efficiency of the heating device. Although the industry has added perforations to the insulating layer to improve thermal conductivity through the penetration of the perforations, when the weight of the user puts pressure on the seat chair, the perforation is squeezed and cannot maintain the original aperture. Therefore, the poor heat conduction of the heating device still needs to be improved.

Please refer to Fig. 1, the ventilated and heated seating structure of the utility model is installed in a car seat 1, and the car seat 1 includes: a seat part 2 for the user to sit on and an end shaft connected to the seat part 2 A back portion 3 extending upward is slightly L-shaped as a whole; and the back portion 3 has the same composition as the seat portion 2 , and the seat portion 2 is used for implementation description.

Please refer to Fig. 2, the sitting structure of the utility model that can be ventilated and heated includes:

An outer layer 10 is to cover the surface of the seat portion 2, and the outer layer 10 is provided with a large number of pores, wherein the outer layer 10 can be any one of genuine leather, artificial leather with hole skin, and woven cloth with a layer of mesh. made up of species.

An inner inner layer 20 is located under the outer layer 10 and is glued and covered with a non-woven fabric 22 on the bottom surface of a foam body 21, and then punched to form a plurality of air holes 211, 221 at the same time, so that the foam body 21 The size and position of the air holes 211 and the air holes 221 of the non-woven fabric 22 are all corresponding as shown in FIG. It can be stitched with the outer layer 10, and the non-woven fabric 22 can increase the strength and toughness of the inner layer 20 and block the transmission of abnormal sound.

An electric heating layer 30 is arranged below the inner layer 20. The electric heating layer 30 has a pad body 31 made of soft material. A linear electric heating element 33 is installed on the pad body 31 and its two ends are connected with a The electric wire 35 is connected, and several through holes 37 are formed between the bends of the electric heating element 33; wherein, the electric heating element 33 can be composed of heat-generating materials such as thermal resistors, electric heating wires, or made in the form of a printed circuit, and the electric heating element The member 33 receives external power from the wire 35 and emits heat.

A three-dimensional distribution layer 40 is located below the electric heating layer 30, and the three-dimensional distribution layer 40 is composed of a plurality of elastic supports 42 between two air-permeable mesh layers 41, wherein the surfaces of the two air-permeable layers are provided with a plurality of air holes, The elastic supporting body 42 is composed of a plurality of independent supporting columns, so air flow passages are naturally formed between the elastic supporting bodies 42 .
