Description

Technical Field

[0001] This utility model relates to the field of seating, specifically a seat cushion with pressure-sensitive heating and ventilation. Background Technology

[0002] A seat cushion is a home or office product used to improve the comfort, support, and protection of a seat. It is widely used in homes, offices, cars, and other places.

[0003] The heating function of existing car seat cushions is usually achieved by using electric heating wires. The heating wires are placed in the seat cushion. When heating the car seat, the heating wires need to be kept powered on, which requires manual control of the power supply. If the goal is to make the seat warm as soon as someone sits down, a device to detect whether someone is sitting on it needs to be installed in the circuit of the heating wires, which would increase the cost of the seat cushion.

[0004] Therefore, a new type of seat cushion with pressure-sensitive heating and ventilation needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a seat cushion with pressure-sensitive heating and ventilation to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure-sensitive heating and ventilation seat cushion, comprising a seat cushion body formed by foaming a foamed material, a covering cover provided on the outside of the body, and a plurality of heating pads provided between the body and the covering cover; the heating pads include piezoelectric ceramics and a high-temperature resistant heat-conducting layer covering the outside of the piezoelectric ceramics, the piezoelectric ceramics generate heat when subjected to pressure, and the heat is conducted to the covering cover through the high-temperature resistant heat-conducting layer, the covering cover being provided with a plurality of ventilation holes.

[0007] Preferably, the bottom of the main body is provided with a support, and the support is provided with a fan that cooperates with the ventilation holes.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] In this invention, a heating pad is installed on the seat cushion, and a piezoelectric ceramic is installed inside the heating pad. The piezoelectric ceramic will heat up when it is subjected to pressure. When the user sits on the seat cushion, the heating pad will heat the seat cushion. When the user leaves, the seat cushion will stop heating. In addition, multiple ventilation holes are opened on the seat cushion, which can be used in hot weather. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] All electronic components in this application are controlled by an external controller.

[0016] Example 1

[0017] Please refer to Figure 1-3 As shown, this utility model provides a seat cushion with pressure-sensitive heating and ventilation, including a seat cushion body 1 made of foamed material, a covering cover 2 on the outside of the body 1, and a plurality of heating pads between the body 1 and the covering cover 2; the heating pads include piezoelectric ceramics 3 and a high-temperature resistant heat-conducting layer 4 covering the outside of the piezoelectric ceramics 3. When the piezoelectric ceramics 3 is subjected to pressure, it generates heat, which is conducted to the covering cover 2 through the high-temperature resistant heat-conducting layer 4. The covering cover 2 is provided with a plurality of ventilation holes 5.

[0018] The main body 1 is made of foamed material, which can be high-resilience polyurethane foam. The cover 2 covers the outside of the main body 1 and can be made of genuine leather. There are multiple heating pads, which are composed of piezoelectric ceramics 3 and high-temperature resistant heat-conducting layers 4. The high-temperature resistant heat-conducting layers 4 encapsulate the piezoelectric ceramics 3 inside. The high-temperature resistant heat-conducting layers 4 can be made of heat-conducting silicone as the base material and ceramic particles as the filler. When the heating pads are under pressure, the piezoelectric ceramics 3 will heat up, and the heat emitted will be transferred to the cover 2 through the high-temperature resistant heat-conducting layers 4. Heat will be generated when the passenger sits on it. Ventilation holes 5 are opened on the cover 2. The foamed material is a porous material to improve the breathability.

[0019] Specifically, the bottom of the main body 1 is provided with a support 6, and the support 6 is provided with a fan 7 that cooperates with the ventilation hole 5. The support 6 can support the seat cushion, and the fan 7 is fixedly installed on the support 6. The fan 7 can be purchased directly from the market. The sweat on the cover 2 is blown into the ventilation hole 5 to improve the ventilation effect of the seat cushion.

[0020] Example 2

[0021] The rest of the structure remains unchanged. The difference from Embodiment 1 is that the high-temperature heat-conducting layer 4 is made of carbon fiber electric heating cloth. The current generated by the piezoelectric ceramic 3 will be passed into the carbon fiber electric heating cloth, which can further improve the heating effect.

[0022] Example 3

[0023] The rest of the structure remains unchanged. The difference from Embodiment 1 is that the heating pad is filled with thermally conductive silicone grease. The thermally conductive silicone grease-filled heating pad can improve the heat conduction effect and improve the thermal utilization rate of the piezoelectric ceramic 3.

[0024] Example 4

[0025] The other structures remain unchanged. The difference from Embodiment 1 is that the rear end of the main body 1 is provided with a connecting buckle 8, and the front part of the bottom of the main body 1 is provided with a felt 9. The connecting buckle 8 can be inserted into the gap between the seat support and the seat back, and the felt 9 can be connected to the seat leg rest, which facilitates the installation of this seat cushion.
