[0031] This application makes improvements and innovations and proposes the following embodiments.
[0032] In some embodiments, please refer to Figures 1 to 4 , a temperature control device for an automobile seat is provided, including: A seat main body 1; the seat main body 1 includes a seat cushion frame 11 and a backrest frame 12; the seat cushion frame 11 is arranged on the vehicle frame; a seat cushion body 13 is arranged on the seat cushion frame 11, and a backrest body 14 is arranged on the backrest frame 12; A temperature control structure 2; the temperature control structure 2 includes: a water tank 22, temperature control pipe fittings 21, a blower 23, an air duct 24, a heater 25, and a cooler 26; the water tank 22 is fixedly arranged in the vehicle frame and is located below the seat cushion frame 11; the water tank 22 has a water inlet and a water outlet, and a water pump 27 is arranged on the water outlet; the temperature control pipe fittings 21 are all communicated with the water inlet and the water outlet of the water tank 22 to form a water cooling circuit; the temperature control pipe fittings 21 penetrate through the seat cushion body 13 and the backrest body 14; the blower 23 is fixedly connected to the seat cushion frame 11, and the outlet of the blower 23 is communicated with the air duct 24; the air duct 24 is fixedly connected to the backrest frame 12, and the air outlet of the air duct 24 is located inside the backrest body 14; the heater 25 is arranged inside the water tank 22, and the cooler 26 is fixedly arranged outside the water tank 22.
[0033] Wherein, the outlet of the blower 23 also extends into the seat cushion body 13 and is communicated with the seat cushion body 13. The blower 23 blows air into the seat cushion body 13, and after being evenly dispersed by the seat cushion body 13, it flows out of the seat cushion body 13, thereby taking away the heat of the user and keeping the seat cushion dry. The outside of the water tank 22 is made of copper, and the cooling part of the cooler 26 is fixedly attached to the outside of the water tank 22. The copper water tank 22 can improve the heat conduction efficiency, facilitating the cold source of the cooler 26 to enter the water tank 22. The seat cushion frame 11 and the backrest frame 12 are rotatably connected.
[0034] The air inlet of the blower 23 is communicated with the air outlet of the vehicle-mounted air conditioner through a pipeline. By introducing the air-conditioned air into the automobile seat, the heating and cooling efficiency of the seat can be improved.
[0035] Enhanced ventilation of the seat cushion body 13 and the backrest body 14 is achieved by setting the blower 23, which timely removes the heat and moisture generated by the user, ensuring that the seat cushion body 13 and the backrest body 14 are dry and breathable, and improving the comfort of use.
[0036] The air from the blower 23 can also accelerate the heat dissipation of the temperature control pipe fitting 21, quickly dissipate the water heated or cooled by the heater 25 or the cooler 26 in the heat dissipation pipe fitting, transfer the heat or cold to the user, realize the temperature adjustment of the seat, and improve the comfort of the seat use.
[0037] At the same time, the cooperation of the temperature control pipe fitting 21 with the heater 25 and the cooler 26 can avoid using heating wires for heating, thereby avoiding the occurrence of electric leakage or burning the sponge and causing a fire.
[0038] In one solution, the temperature control pipe fitting 21 includes a main pipe 211, branch pipes 212, and a return pipe 213; the main pipe 211 is communicated with the water outlet of the water tank 22; the main pipe 211 and the return pipe 213 are communicated through the branch pipes 212; the number of the branch pipes 212 is multiple, and the multiple branch pipes 212 are arranged at intervals along the extension direction of the main pipe 211; the return pipe 213 is communicated with the water inlet of the water tank 22. The multiple branch pipes 212 are arranged at intervals along the extension direction of the main pipe 211, which can make the cold or heat evenly distributed on the seat cushion body 13 and the backrest body 14. Improve the user experience.
[0039] Specifically, the sizes of the main pipe 211, the branch pipes 212, and the return pipe 213 located in the seat cushion body 13 are smaller than those of the main pipe 211, the branch pipes 212, and the return pipe 213 located in the backrest body 14. This design can ensure that the water flow rate in the seat cushion body 13 is the same as that in the backrest body 14. Ensure that the cooling capacity and heating capacity of the seat cushion body 13 and the backrest body 14 are basically the same.
[0040] In one solution, the cooler 26 is externally coated with a heat insulation layer. Setting the heat insulation layer can reduce the cold loss of the cooler 26 and ensure that more cold can be absorbed by the water tank 22.
[0041] Specifically, the temperature control pipe fitting 21 is a plastic pipe with toughness. The plastic pipe with toughness is easy to bend, deform and be stretched, which can facilitate the temperature control pipe fitting 21 to adapt to the extrusion of users with different weights and still ensure no breakage after being impacted to different degrees, reducing the occurrence of the phenomenon of the temperature control pipe fitting 21 breaking and leaking water.
[0042] In one solution, the seat cushion body 13 and the backrest body 14 sequentially include a foam sponge 141, a mesh layer 142, and a bracket 143 from the inside to the outside; the foam sponge 141 is located inside the bracket 143, and the mesh layer 142 is sleeved on the bracket 143; the bracket 143 is fixedly connected to the backrest frame 12. The foam sponge 141 is provided with good softness and air permeability, improving the comfort of the seat body. The mesh layer 142 facilitates the smooth outflow of air from the seat body, improving the heat dissipation effect. At the same time, the mesh layer 142 has good tensile strength, and sleeving it on the bracket 143 can improve the strength of the seat body.
[0043] In one solution, the bracket 143 is an elastic arc-shaped rod. The mesh layer 142 is sleeved on the bracket 143 to form a space for accommodating the foam sponge 141, with a reasonable design. When the mesh layer 142 is under pressure, the foam sponge 141 undergoes elastic deformation, and the bracket 143 also undergoes elastic deformation, absorbing energy and reducing the impact force.
[0044] Specifically, the outside of the mesh layer 142 is covered with a genuine leather cover, and a plurality of evenly distributed holes are opened on the genuine leather cover, ensuring that wind can flow out from the holes and ensuring the comfort of the user.
[0045] In one solution, the cooler 26 is a thermoelectric cooler 26. Using the thermoelectric cooler 26, it has no noise, no vibration, does not require a refrigerant, is small in size and light in weight, and is suitable for being assembled on an automobile.
[0046] Specifically, the thermoelectric cooler 26 refers to using the thermoelectric effect of a semiconductor to produce cooling capacity. After the power is turned on, electron-hole pairs are generated near the upper contact point, the internal energy decreases, the temperature drops, and heat is absorbed from the outside, which is called the cold end. At the other end, due to the recombination of electron-hole pairs, the internal energy increases, the temperature rises, and heat is released to the environment, which is called the hot end. The temperature difference and cooling capacity generated by a pair of semiconductor thermoelectric elements are very small. A practical thermoelectric cooler 26 is composed of many pairs of thermoelectric elements connected in parallel and in series, also called a thermopile. A single-stage thermopile can obtain a temperature difference of about 60 °C, that is, the cold end temperature can reach -10 to -20 °C.
[0047] In one solution, it further includes a controller 3; the blower 23, the cooler 26, the heater 25, and the water pump 27 are all electrically connected to the controller 3. The controller 3 is used to control the start and stop of the blower 23, the cooler 26, the heater 25, and the water pump 27 to cooperate to achieve the adjustment of the temperature of the car seat. The degree of automation of temperature adjustment is improved.
[0048] In one solution, it further includes a temperature sensor 4 and a humidity sensor 5, and both the temperature sensor 4 and the humidity sensor 5 are electrically connected to the controller 3; the temperature sensor 4 and the humidity sensor 5 are both arranged within the foamed sponge 141 layer. The temperature sensor 4 and the humidity sensor 5 can transmit temperature and humidity signals to the processor in real time, and the processor controls the power of the blower 23 and the power of the water pump 27, the cooler 26 or the heater 25 to be adjusted so that the temperature and humidity are at a predetermined value, realizing the automatic adjustment of temperature and humidity and improving the temperature adjustment automation degree of the temperature adjustment structure 2.
[0049] Specifically, both the temperature sensor 4 and the humidity sensor 5 are close to the mesh layer 142; the temperature and humidity of the user at this moment can be detected better and more accurately.
[0050] Specifically, when the temperature value output by the temperature sensor 4 is between 0 - 10 °C, the corresponding power of the water pump 27 is 10 watts; when the temperature value output by the temperature sensor 4 is between 11 - 20 °C, the corresponding power of the water pump 27 is 15 watts; when the temperature value output by the temperature sensor 4 is between 21 - 50 °C, the corresponding power of the water pump 27 is 25 watts; when the temperature value output by the temperature sensor 4 is greater than 50 °C or less than 0 °C, the corresponding power of the water pump 27 is 30 watts. The power adjustment of the water pump 27 is achieved through a frequency converter, which improves the refrigeration efficiency while ensuring energy consumption.
[0051] The frequency converter is electrically connected to the processor.
[0052] When the difference between the set temperature of the user and the temperature of the temperature sensor 4 is within 10 °C, the power of the blower 23 is 10 watts; when the difference between the set temperature of the user and the temperature of the temperature sensor 4 is more than 11 °C, the power of the blower 23 is 20 watts. When the temperature difference is large, the ventilation volume needs to be increased to ensure better heat dissipation or heating.
[0053] When the temperature value output by the temperature sensor 4 is lower than 30 °C, the heater 25 is started at this time and the cooler 26 is turned off; when the temperature value output by the temperature sensor 4 is higher than 30 °C, the cooler 26 is started at this time and the heater 25 is turned off.
[0054] The processor is electrically connected to the vehicle-mounted processor and the processor is electrically connected to the vehicle-mounted display screen. It is convenient for the user to issue instructions through the vehicle-mounted display screen, and then control the start and stop of the blower 23, the cooler 26, the heater 25, and the water pump 27.
[0055] The processor is powered by the vehicle-mounted power supply, and at the same time, the blower 23, the cooler 26, the heater 25, and the water pump 27 are all connected to the vehicle-mounted power supply.
[0056] Specifically, wires are provided on the main pipe 211, the branch pipe 212, and the return pipe 213. When the wire is broken, it indicates that the pipe body is broken. The wire is connected to a detection sensor 8. When the wire is broken, the current signal flowing into the sensor changes. The detection sensor 8 transmits the signal to the processor, and the processor controls the water pump 27 to stop working.
[0057] The branch pipe 212 is inclined, that is, the two ends of the branch pipe 212 are not on the same horizontal plane, and the branch pipe 212 is a straight pipe. After the water pump 27 stops working, all the water can flow back into the water tank 22, reducing the situation where water flows out of the branch pipe 212 after the branch pipe 212 is broken.
[0058] In one solution, it further includes: a water pressure sensor 6 and a pressure sensor 7; both the pressure sensor 7 and the water pressure sensor 6 are electrically connected to the processor; the water pressure sensor 6 is located at the water outlet of the water pump 27, and the pressure sensor 7 is located inside the seat cushion body 13. The water pressure sensor 6 is provided to detect the water pressure situation. When the water pressure suddenly drops below the threshold during the normal operation of the water pump 27, it indicates that the temperature regulating pipe fitting 21 is broken, and the processor controls the water pump 27 to stop working to prevent more water from flowing out. The pressure sensor 7 is used to automatically start the seat temperature regulation and ventilation after a user sits on the seat. That is, after the pressure value output by the pressure sensor 7 is higher than the threshold, the controller 3 controls the fan 23 and the water pump 27 to start, and at the same time determines whether to start the heater 25 or the cooler 26 according to the temperature value set by the user.
[0059] Specifically, flow sensors are provided at both the water inlet and the water outlet of the water tank 22. When the output value of the flow sensor at the water outlet is greater than the output value of the flow sensor at the water inlet, it indicates that a part of the water flows out of the temperature regulating pipe fitting 21. At this time, the processor controls the water pump 27 to stop working.
[0060] In one solution, a water-absorbing resin layer is provided inside the foamed sponge 141 layer, and the water-absorbing resin layer covers the outside of the temperature regulating pipe fitting 21. The setting of the water-absorbing resin layer can ensure that water is absorbed immediately after leakage, preventing water from flowing out of the seat main body 1 and affecting the user experience.
[0061] Specifically, the water-absorbing resin layer is made of starch and acrylate, and the amount of pure water absorbed is 50 to 100 times its own weight.
[0062] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, replacements, and variations to the above embodiments within the scope of the present invention.
