[0038] In actual application of this embodiment, the multifunctional cooling pad is used in actual use. The main structure of the cooling pad is composed of a main base 101 and a top sheet 102. A gap cavity is provided between the main base 101 and the top sheet 102. A plurality of cooling modules 2 are provided in the gap cavity. The cooling modules 2 are arranged in an array along a first direction x and a second direction y, and two adjacent cooling modules 2 are arranged at intervals. A gasket assembly 3 and a bracket assembly 4 are provided in the cooling module 2. A pad base 301 is provided on the bottom side of the gasket assembly 3. A flexible sponge layer 303 is provided on the pad base 301, and a heat dissipation pipe 306 arranged in an S-shaped ring is provided on the top of the sponge layer 303. The heat dissipation pipe 306 is used to transport cooling water for cooling. A bracket base 401 is arranged at the bottom of the pad base 301. The bracket base 401 is fixedly arranged on the main base 101, and a guide hole 402 is also arranged in the middle of the bracket base 401. The sliding frame 403 is elastically inserted in the guide hole 402 so that the sliding frame 403 can move elastically in the third direction z. A plurality of guide rods 404 are also arranged circumferentially on the sliding frame 403. The guide rods 404 are slidably assembled on the guide hole 402 to limit the self-rotation of the sliding frame 403 during the sliding process. The sliding frame 403 is movably connected to the pad base 301, and a plurality of cooling The module 2 array is arranged on the main base 101. Therefore, when the cooling pad is in use, when the user's torso lies on the top sheet 102, since the torso part is not completely in contact with the top sheet 102, the top sheet 102 in contact with the torso and the sponge layer 303 at the bottom thereof are deformed under the action of pressure, and at the same time, the sponge layer 303 at this position is subjected to pressure, so that the sponge layer 303 and the pad base 301 move synchronously along the negative direction of the third direction z, and then the sliding frame 403 moves synchronously toward the guide hole 402. A guide unit for controlling the flow of cooling water is arranged between the guide hole 402 and the sliding frame 403. The guide unit adjusts the cooling water flow rate by the pressure. The flow rate of water per unit time, and then when the pressure between the user's torso and the cooling pad is large during the user's sitting or lying process, the temperature will continue to rise due to the poor air flow at the pressure point. At this time, the flow rate of the cooling water at this point is controlled by the guide unit to increase, so that the cooling water can continuously take away the heat at the pressure point during the flow in the heat dissipation pipe 306, and can automatically adjust the heat dissipation position as the user's posture changes to ensure that it is always closely fitted to the heat accumulation area of ​​the human body to achieve precise cooling. When any point on the cooling pad is not subject to pressure, the guide unit at this point is in a closed state to stop the cooling water at this point from flowing, thereby reducing the ineffective cooling process.

[0039] Furthermore, the top sheet 102 can adopt a multi-layer composite structure, the first layer is preferably a PU film layer, which can increase the waterproof penetration performance; the second layer is preferably a printed fabric layer, which can freely choose the style and color; the third layer is preferably a gel layer, which has a cool and soft physical property. It is not only suitable for various fields such as medical care, office, home, outdoor and automobile, but also can be customized according to the needs of the pattern, thickness, size and style.

[0040] Furthermore, the sponge layer 303 preferably adopts a composite sponge layer and a thickened sponge layer.

[0041] Furthermore, an anti-slip layer is provided at the bottom of the main base 101 .

[0042] See also Figure 4 In a preferred embodiment of the present invention, the gasket assembly 3 further includes a side mounting groove 302, and an annular side mounting groove 302 is provided on the side of the pad base 301, and any two adjacent side mounting grooves 302 are connected by a flexible fabric.

[0043] In actual application of this embodiment, the side of the pad base 301 is provided with an inwardly recessed side groove 302, and any adjacent side grooves 302 are connected by flexible fabric assembly, and the flexible fabric is sewn and assembled in the side groove 302, so that when any cooling module 2 is tilted and flipped, the cooling module 2 always maintains a connected state with the other cooling modules 2, avoiding the side cooling module 2 from being recessed under the action of pressure, thereby preventing the comfort of the seat cushion from being affected by local recessing.

[0044] See also Figure 4 In a preferred embodiment of the present invention, the gasket assembly 3 also includes a tube groove 304, a connecting port 305 and an interface tube 307.

[0045] In actual application of this embodiment, a tube groove 304 is provided on the sponge layer 303, and the heat dissipation pipe 306 is embedded in the tube groove 304, and the two ends of the heat dissipation pipe 306 pass through the connecting port 305 respectively and are connected to the interface pipe 307. Since the heat dissipation pipe 306 is embedded in the tube groove 304, the surface of the seat cushion is flat, reducing discomfort during use.

[0046] Furthermore, the heat dissipation pipe 306 is arranged in an S-shaped coil on the top of the sponge layer 303, thereby increasing the flow time of cooling water in the heat dissipation pipe 306, and at the same time increasing the heat exchange area between the surface of the heat dissipation pipe 306 and the external environment, thereby increasing the thermal conductivity and improving the cooling effect.

[0048] In actual application of this embodiment, the regulating valve body 405 is fixedly arranged on the guide hole 402, and the regulating needle 406 is fixedly arranged on the sliding frame 403, so that when the seat cushion is in use, when one side of the sponge layer 303 is subjected to pressure to make the pad base 301 move in the negative direction of the third direction z, the sliding frame 403 moves synchronously in the negative direction of the third direction z. At this time, the regulating needle 406 slides synchronously into the regulating valve body 405 to increase the orifice in the water inlet 407, thereby allowing the cooling water pumped into the water inlet 407 to be input into the regulating valve body 405 along the water inlet 407, and flows along the regulating valve body 405 and the interface pipe 307 to the heat dissipation pipe 306, thereby automatically adjusting the pump flow rate of the cooling water according to the pressure at the point.
