Detailed Implementation

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0040] Please see Figure 1 and Figure 2This application provides a seat that can be used in automobiles as car seats, in offices as office chairs, even as dining tables as dining chairs, or as study chairs, etc. The application is not limited to any particular type of seat, as long as it can regulate temperature and utilize heat energy for charging to supply electrical energy to other devices, it is protected under this application. The seat includes a main body 1, an inner liner 2, and one or more temperature-controlled power generation devices 3. The main body 1 refers to the overall frame of the seat, including the supporting structure and the seat's outer covering, which can be made of fabric, leather, etc., without limitation. The inner liner 2 is located inside the main body 1 and is mainly used to fill the internal space of the main body 1. The inner liner 2 can be made of polyurethane foam. At least one mounting groove is defined in the inner liner 2, and the temperature-controlled power generation device 3 is located within the mounting groove. By using the temperature-controlled power generation device 3 to regulate the temperature of the seat cover, the comfort of use is improved. The temperature-controlled power generation device 3 can also use the temperature difference between the packaging cover and the inner lining 2 to convert heat energy into electrical energy to achieve the purpose of charging. In turn, the seat can be used as a temporary charging device to charge other devices.

[0041] Please see Figure 2 and Figure 3 The temperature-controlled power generation device 3 is connected to an external power source 7. Relying on the electrical energy provided by the external power source 7, it releases and absorbs heat to regulate temperature. The temperature-controlled power generation device 3 includes an energy storage device 31, an energy conversion component 32, and a mode switching device 33. The energy storage device 31 stores and releases energy; this energy storage device 31 can be a battery. The energy conversion component 32 is connected to the energy storage device 31 and the external power source 7. The mode switching device 33 is connected to the energy conversion component 32, the energy storage device 31, and the external power source 7. The mode switching device 33 is used to connect the energy conversion component 32 and the energy storage device 31, allowing the energy conversion component 32 to convert heat energy into electrical energy and charge the energy storage device 31. Alternatively, the mode switching device 33 can connect the energy conversion component 32 and the external power source 7, allowing one side of the energy conversion component 32 to absorb or release heat based on the electrical energy provided by the external power source 7. Here, "one side of the energy conversion component 32" refers to the side closest to the packaging surface, facilitating temperature control of the packaging surface and its vicinity.

[0042] The technical solution provided in this application utilizes a mode switching device 33 to switch the circuit between the energy conversion component 32 and the energy storage device 31, and between the energy conversion component 32 and the external power supply 7. This allows the temperature-controlled power generation device 3 to achieve both temperature control and energy recovery, converting heat energy into electrical energy to charge the energy storage device 31 and reducing energy waste. Furthermore, both temperature control and energy recovery are achieved using the energy conversion component 32, eliminating the need for additional energy conversion components for temperature control or energy recovery, thus saving costs.

[0043] In some embodiments, see Figure 2 and Figure 3 The energy conversion component 32 includes multiple energy conversion units 321 connected in series. Each energy conversion unit 321 is composed of a P-type semiconductor 3212 and an N-type semiconductor 3211 directly connected by a conductive element, such as a copper or aluminum sheet, forming a continuous current path. When the external power supply 7 supplies power, the current flows sequentially through each energy conversion unit 321, achieving efficient heat conduction between the seat surface and interior through the Peltier effect. Furthermore, the series-connected energy conversion component 32 significantly increases the total output voltage and enhances power generation capacity by superimposing the thermoelectric potential of each energy conversion unit 321. Multiple energy conversion units 321 are evenly distributed in different areas of the seat, which can capture local temperature differences more widely and avoid the efficiency reduction caused by insufficient temperature difference in a single unit. This results in a more uniform temperature distribution during temperature control, improving comfort. It maximizes energy recovery efficiency during power generation, and the series layout simplifies circuit complexity, reduces modular assembly costs, and is suitable for flexible adaptation to seats of different sizes.

[0044] Furthermore, along the direction of current flow, the mode switching device 33 is connected to the energy conversion unit 321 at the beginning, and the energy storage device 31 and the external power supply 7 are both connected to the energy conversion unit 321 at the end. By connecting the mode switching device 33 to the energy conversion unit 321 at the beginning of the current flow direction, and connecting the energy storage device 31 and the external power supply 7 to the energy conversion unit 321 at the end, a unidirectional series path is formed. This allows the current to flow from the beginning through all the energy conversion units 321 to the energy storage device 31 at the end in charging mode, thereby increasing the total output voltage by superimposing the thermoelectric potential generated by each unit. At the same time, the centralized connection of the external power supply 7 and the energy storage device 31 at the end simplifies the circuit design for multi-mode switching and reduces connection node losses.

[0045] It should be noted that the electrical energy output by the energy storage device 31 is mainly intended for other small power devices, such as mobile phones. The electrical energy input to the energy storage device 31 is converted into electrical energy by the energy conversion component 32. This energy is primarily generated by the temperature difference between the seat surface and the seat interior. This temperature difference can be determined based on actual conditions. For example, in summer, the seat surface is exposed to sunlight, causing its temperature to be much higher than that of the lining 2. This causes charge carriers in the energy conversion unit 321 to move from the high-temperature end (closer to the seat surface) to the low-temperature end (away from the seat surface), accumulating on the side away from the seat surface. This creates a potential difference within the energy conversion unit 321. Simultaneously, this potential difference generates a reverse charge flow. When the thermally moving charge flow reaches dynamic equilibrium with the internal electric field, a stable thermoelectric potential is formed across the energy conversion unit 321, generating a current that flows into the energy storage device 31, thus charging the energy storage device 31.

[0046] In some embodiments, see Figure 2 and Figure 3 Each energy conversion unit 321 includes an N-type semiconductor 3211 and a P-type semiconductor 3212, with the N-type semiconductor 3211 and the P-type semiconductor 3212 connected. Each energy conversion unit 321 forms an independent thermocouple pair by connecting the N-type semiconductor 3211 and the P-type semiconductor 3212. When current flows through, heat absorption or release occurs at the NP junction based on the Peltier effect, achieving precise local temperature control. At the same time, the complementary characteristics of the N-type semiconductor 3211 and the P-type semiconductor 3212 generate a high-efficiency thermoelectric potential through carrier migration at the hot and cold ends during charging mode.

[0047] Furthermore, multiple energy conversion units 321 are arranged in an array, with multiple N-type semiconductors 3211 and multiple P-type semiconductors 3212 arranged alternately. By arranging multiple energy conversion units 321 in an array, and alternating N-type semiconductors 3211 and P-type semiconductors 3212 in both row and column directions (e.g., alternating rows m and m-1 rows of N-type semiconductors 3211 and P-type semiconductors 3212, and alternating columns n and n-1 columns of N-type semiconductors 3211 and P-type semiconductors 3212), a periodically distributed thermocouple pair network is formed. This allows the NP junctions of adjacent units to form a continuous path through conductive elements when current flows through them. The complementary characteristics of the alternating arrangement enhance the uniformity of heat conduction in temperature control mode, avoiding local temperature gradient imbalance. At the same time, in charging mode, the synergistic effect of multiple pairs of N-type semiconductors and P-type semiconductors in the array expands the effective temperature difference coverage area, significantly improving the overall thermoelectric conversion efficiency. Moreover, the regular array layout reduces wire length and connection nodes, reducing resistance loss and thermal stress concentration.

[0048] In some embodiments, in each energy conversion unit 321, an N-type semiconductor 3211 and a P-type semiconductor 3212 constitute a semiconductor device. Each energy conversion unit 321 also includes a first conductive element 322, which is disposed on one side of the semiconductor device. Each first conductive element 322 is connected to the N-type semiconductor 3211 and the P-type semiconductor 3212 in one energy conversion unit 321. Each energy conversion unit 321 achieves the physical connection of the NP junction by fixing the N-type semiconductor 3211 and the P-type semiconductor 3212 to the same plane and jointly constituting the semiconductor device, and by providing the first conductive element 322, such as a copper sheet or an aluminum sheet, on one side, forming a directional current flow path within the unit. When an external power supply 7 is input, the current is evenly distributed from the first conductive element 322 to the N-type and P-type semiconductors 3212. The Peltier effect is used to concentrate the release or absorption of heat on the other side of the semiconductor device, ensuring efficient conversion of hot and cold surfaces within a single energy conversion unit 321. At the same time, the integrated design of the first conductive element 322 reduces the connection interface resistance and thermal resistance, improving energy transmission efficiency.

[0049] Furthermore, the energy conversion component 32 also includes a plurality of second conductive elements 323. The second conductive elements 323 are disposed on the side of the energy conversion unit 321 away from the first conductive element 322, and each second conductive element 323 is connected to two adjacent semiconductors in two adjacent energy conversion units 321. By providing a plurality of second conductive elements 323, such as copper or aluminum sheets, on the side of the energy conversion unit 321 away from the first conductive element 322, each second conductive element 323 is directly connected across adjacent semiconductors in two adjacent energy conversion units 321, such as between the P-type semiconductor 3212 of the left energy conversion unit 321 and the N-type semiconductor 3211 of the right energy conversion unit 321, forming a continuous series current path. By leveraging the complementary semiconductor characteristics of adjacent units, the total output voltage is increased through the temperature difference superposition effect in charging mode. At the same time, in temperature control mode, the current is ensured to flow evenly through all units to enhance the consistency of heat conduction. The short-distance direct connection design of the second conductive element 323 reduces the wire length and contact resistance, thereby reducing energy loss and the risk of local overheating. Furthermore, the modular connection method facilitates large-scale assembly and replacement of faulty units. Thus, while optimizing thermoelectric conversion efficiency and improving system reliability, it also achieves a compact structure and a significant reduction in production costs.

[0050] In some embodiments, see Figure 3 and Figure 5The mode switching device 33 includes a first switch 331, which is used to turn on the external power supply 7 and the energy conversion component 32, and control the current in the energy conversion component 32 to flow in a first direction to form a heating circuit. By setting the first switch 331, such as a metal-oxide-semiconductor field-effect transistor (MOSFET) or a relay as the mode switching device 33, the positive terminal of the external power supply 7 is connected to the first end of the energy conversion component 32, and the negative terminal of the external power supply 7 is connected to the end. When the first switch 331 is closed, the driving current of the external power supply 7 flows through all the energy conversion units 321 in the first direction. Based on the Peltier effect, heat is concentrated on one side of the energy conversion component 32 to form a heating circuit. Its directional current control avoids reverse current interference. At the same time, the single conduction mode of the series path simplifies the circuit logic and reduces the complexity of multi-switch coordination.

[0051] Furthermore, the mode switching device 33 includes a second switch 332, which is used to turn on the external power supply 7 and the energy conversion component 32, and control the current in the energy conversion component 32 to flow in a second direction to form a cooling circuit, wherein the first direction is opposite to the second direction. By setting a second switch 332, such as a MOSFET or a relay, connected in parallel with the first switch 331 in the opposite direction between the external power supply 7 and the energy conversion component 32, when the second switch 332 is closed, the external power supply 7 drives the current to flow through the energy conversion component 32 in a second direction opposite to the first direction. Based on the Peltier effect, one side of the energy conversion component 32 absorbs heat to form a cooling circuit. By independently controlling the two switches to switch on and off at different times, the cooling and heating modes can be switched quickly. Moreover, the reverse current path and the forward current path share the same series structure, without the need to add additional circuit branches. This retains the efficient temperature difference superposition characteristics of the series layout, and gives the system the ability to switch between cooling and heating flexibly through bidirectional current control. At the same time, it avoids multi-path cross interference, reduces circuit complexity and energy consumption, thereby significantly improving the user's freedom to adjust the seat temperature in real time while ensuring cooling efficiency and temperature control accuracy, and meeting the dynamic comfort needs in complex environments.

[0052] In some embodiments, the mode switching device 33 includes a third switch 333, which is used to turn on the energy storage device 31 and the energy conversion component 32 so that the energy conversion component 32 converts thermal energy into electrical energy and charges the energy storage device 31. By setting a third switch 333, such as a MOSFET or relay, the energy storage device 31 and the energy conversion component 32 are independently connected. When a temperature difference is detected between the seat surface and the interior, the third switch 333 is closed, cutting off the external power supply circuit 7 and conducting the current path from the energy conversion component 32 to the energy storage device 31. This allows each energy conversion unit 321 to directly convert thermal energy into electrical energy based on the Seebeck effect and input it into the energy storage device 31. Its independent control logic avoids circuit conflicts with the heating / cooling mode. At the same time, the charging efficiency is improved by superimposing the thermoelectric potential of all units in the series structure. There is no need to add an additional dedicated power generation circuit module. The energy recovery capability is maximized by utilizing the multi-unit synergy of the existing energy conversion component 32. Thus, while simplifying the system architecture and reducing energy consumption, it enables continuous waste heat power generation in the vehicle's off-state or non-temperature-controlled state, enhancing the practicality and environmental adaptability of energy self-circulation.

[0053] In some embodiments, a diode 34 is electrically connected between the energy storage device 31 and the energy conversion component 32. The diode 34 is used to prevent the energy storage device 31 from outputting current to the energy conversion component 32. By connecting a unidirectional diode 34, such as a silicon diode 34 or a Schottky diode 34, in series in the circuit between the energy storage device 31 and the energy conversion component 32, current can only flow from the energy conversion component 32 to the energy storage device 31. In charging mode, the electromotive force generated by the temperature difference is used to achieve stable charging by unidirectionally inputting the energy storage device 31 through the diode 34. At the same time, the high reverse impedance characteristic of the diode 34 blocks the path that the energy storage device 31 may discharge in reverse to the energy conversion component 32 in temperature control mode, avoiding energy loss and semiconductor component overload risk caused by energy backflow. Furthermore, physical isolation of the charging and discharging paths can be achieved without the need for additional complex control circuits. This simplifies system design, reduces maintenance costs, ensures the safety and energy recovery efficiency of the charging and discharging process of the energy storage device 31, and extends the service life of the semiconductor device.

[0054] In some embodiments, see Figure 2 and Figure 3The seat also includes a first heat-conducting element 4 and a second heat-conducting element 5. The first heat-conducting element 4 and the second heat-conducting element 5 are respectively disposed on the side of the temperature-controlled power generation device 3 near the front side of the seat and the side near the rear side of the seat. By attaching the first heat-conducting element 4, such as copper foil, graphite sheet, or ceramic sheet, to the surface of the temperature-controlled power generation device 3 near the front side of the seat, and fixing the second heat-conducting element 5, such as copper foil, graphite sheet, or ceramic sheet, to the surface of the device near the rear side of the seat, the heat from the passenger contact area is quickly transferred to the heat-absorbing end of the energy conversion component 32 using highly thermally conductive materials, and the waste heat from the back of the device is efficiently conducted away from the vehicle body or environment. This achieves bidirectional heat flow optimization management on the front and rear sides, enhances the thermal coupling efficiency between the seat surface and the semiconductor, ensures real-time response and uniform distribution of temperature changes in temperature control mode, and maximizes thermoelectric conversion efficiency through the temperature difference between the front and rear sides in charging mode. The physical isolation design of the dual heat-conducting elements avoids thermal interference between the hot and cold ends, thereby improving user comfort and system energy efficiency while simplifying the thermal management structure and reducing thermal fatigue loss during long-term use.

[0055] In some embodiments, see Figure 2 and Figure 4 The seat also includes a phase change element 6, which is located on the side of the second heat conductor 5 away from the temperature control power generation device 3. By fixing the phase change element 6 to the side of the second heat conductor 5 away from the temperature control power generation device 3, the high latent heat characteristic of the phase change element 6 absorbs the waste heat transferred by the second heat conductor 5 and stores it as phase change energy. When the seat surface temperature fluctuates, the phase change element 6 slowly releases the stored heat through solid-solid phase change to balance the ambient temperature difference. Its sealed encapsulation design avoids material leakage and ensures a tight fit with the second heat conductor 5, thereby delaying heat return and enhancing temperature stability in temperature control mode. At the same time, in charging mode, it improves thermoelectric conversion efficiency by stabilizing the temperature difference between the hot and cold ends, and achieves passive regulation of seat temperature without additional energy input, reducing system energy consumption and extending the life of semiconductor devices, while improving the passenger's comfort experience in dynamic environments.

[0056] Furthermore, the phase change material 6 includes a shell 61 and a phase change material 62, with the phase change material 62 filling the shell 61. The shell 61 is made of rubber, possessing good ductility, allowing it to transform into various shapes under high pressure and preventing leakage of the phase change material 62. The phase change material 62 is erythritol, a bio-based phase change material with a phase change temperature of 118°C. Its raw materials are derived from corn, sugarcane, and other substances. Furthermore, this phase change material 62 undergoes a solid-solid phase change, exhibiting environmental friendliness and leak-proof characteristics.
