[0025] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0026] Reference below Figure 1-Figure 4 A seat headrest 1 according to an embodiment of the present invention will be described.

[0027] like Figure 1 and Figure 2 As shown, the seat headrest 1 according to the embodiment of the present invention comprises: a surrounding part 10 and a heat exchange component 20. The surrounding part 10 can mainly control the overall appearance of the seat headrest 1, and other components can be installed and designed inside, and the heat exchange component 20 can mainly realize the temperature adjustment of the front and back of the seat.

[0028] like Figure 1 and Figure 2As shown, the upper end of the enclosure 10 is provided with an air inlet 100, and the lower end of the enclosure 10 is provided with an air outlet 101. The upper and lower ends of the enclosure 10 are provided with the air inlet 100 and the air outlet 101 respectively. The air inlet 100 can mainly play the role of air intake, and a large amount of air can enter the seat headrest 1 through the air inlet 100. The air outlet 101 can mainly play the role of air discharge, and the air outlet 101 can blow the internal air out of the seat headrest 1, so as to achieve the temperature change of the seat. Among them, the air outlet 101 can be multiple, and can be arranged side by side or discretely.

[0029] like Figure 1 and Figure 2 As shown, the heat exchange component 20 is arranged in the enclosure 10, and the airflow enters the enclosure 10 from the air inlet 100, and is discharged through the air outlet 101 after heat exchange in the heat exchange component 20. The heat exchange component 20 can be arranged inside the enclosure 10, and the space inside the enclosure 10 can be reasonably utilized to reduce the space occupation, thereby solving the space layout problem of the seat headrest 1. The airflow enters the enclosure 10 from the air inlet 100, and is discharged through the air outlet 101 after heat exchange in the heat exchange component 20. That is to say, a large amount of air can enter the enclosure 10 through the air inlet 100, and after heat exchange in the heat exchange component 20, the air inside the enclosure 10 is blown out of the seat headrest 1 through the air outlet 101, thereby realizing the temperature change of the seat, which can solve the temperature demand of people in a certain area in the car, and the seat headrest 1 is closer to the people sitting in the car, so that heating or cooling can be realized more quickly. It should be noted that the heat exchange component 20 can cooperate with the vehicle air conditioner to achieve cooling of the entire vehicle or increase the heating rate. It can also be used independently of the vehicle air conditioner. On the one hand, since the heat exchange component 20 is directly electrically driven for energy conversion, the temperature fluctuation control can be more precise. On the other hand, the heat exchange component 20 is arranged independently of the vehicle air conditioner, which can prevent the inability to adjust the temperature in the vehicle in time after a vehicle air conditioner failure.

[0030] Therefore, a heat exchange component 20 is directly arranged in the seat headrest 1, and the heat exchange component 20 can cool and heat, thereby solving the temperature demand of people in a certain area in the car, and the seat headrest 1 is closer to the people in the car, so heating or cooling can be achieved more quickly.

[0031] Specifically, Figure 1-Figure 3As shown, the heat exchange assembly 20 includes: a heating element 200 and a cooling element 201. Compared with the heating element 200, the cooling element 201 is arranged close to the air outlet 101. The heating element 200 and the cooling element 201 are components of the heat exchange assembly 20. The heating element 200 can mainly play a heating role, and the cooling element 201 can mainly play a cooling role. The heating element 200 and the cooling element 201 can both achieve temperature adjustment in front of and behind the seat. Compared with the heating element 200, the cooling element 201 is arranged close to the air outlet 101, that is, the heating element 200 and the cooling element 201 are arranged close to one end of the air inlet 100 and the air outlet 101, respectively. It should be noted that the heating element 200 and the cooling element 201 can be other structural forms besides the circular sleeve type. For example, the heating element 200 and the cooling element 201 can both be square stacked types, or the heating element 200 and the cooling element 201 can be other forms of alternating stacking, and even more, the heating element 200 and the cooling element 201 can be used as a module separately.

[0032] Among them, Figure 1-Figure 3 As shown, the heating element 200 is connected to the inner wall of the enclosure 10, and the airflow entering from the air inlet 100 passes through the heating element 200 to the refrigeration element 201, or the heating element 200 defines an airflow channel between the air inlet 100 and the refrigeration element 201, and the heating element 200 selectively heats the airflow in the airflow channel. The heating component 200 is connected to the inner wall of the surrounding component 10, and the airflow entering from the air inlet 100 passes through the heating component 200 to the refrigeration component 201. A large amount of air can enter the surrounding component 10 through the air inlet 100, and the airflow passes through the heating component 200 to the refrigeration component 201, or the heating component 200 defines an airflow channel between the air inlet 100 and the refrigeration component 201, and the heating component 200 selectively heats the airflow in the airflow channel. The heating component 200 can also define an airflow channel between the air inlet 100 and the refrigeration component 201, and the heating component 200 selectively heats the internal airflow, thereby realizing temperature adjustment in front of and behind the seat.

[0033] In addition, if Figure 1-Figure 3 As shown, the heating element 200 is a PTC heating element or a film heating element. Both the PTC heating element and the film heating element can play a heating role. The heating element 200 is set as one of the PTC heating element and the film heating element. At this time, the heating element 200 is more in line with the actual working conditions and can achieve temperature conversion. Among them, the heating element 200 can be constructed in other forms besides the PTC heating element or the film heating element.

[0034] Of course, if Figure 1-Figure 3As shown, the refrigeration component 201 is constructed as a semiconductor refrigeration plate in the form of a Tesla valve structure. The semiconductor refrigeration plate can mainly play a refrigeration role. The refrigeration component 201 is constructed as a semiconductor refrigeration plate in the form of a Tesla valve structure. At this time, the refrigeration component 201 is more in line with the actual working conditions, and can achieve temperature conversion, cooling, and the cooling area is more accurate. It should be noted that the slit area composed of the Tesla valve structure is a necessary area after the air temperature is adjusted regardless of whether the seat headrest 1 is in heating mode or cooling mode. The airflow flowing through the slit has a unidirectional conduction effect, which can prevent the heat exchange component 20 from generating a backdraft phenomenon when the air is discharged and generating noise that affects the comfort of the occupants. Among them, the refrigeration component 201 can be constructed in other forms besides the semiconductor refrigeration plate.

[0035] Furthermore, if Figure 4 As shown, the seat headrest 1 also includes: an energy storage component, which is arranged in the surrounding component 10, and the refrigeration component 201 is provided with a cold end 202 and a hot end 203, the cold end 202 is arranged adjacent to the air outlet 101, the hot end 203 is arranged adjacent to the air inlet 100, and the hot end 203 is connected to the energy storage component. The energy storage component is a component of the seat headrest 1, which can mainly play an energy storage role, the energy storage component is arranged in the surrounding component 10, and the surrounding component 10 is provided with an energy storage component inside, the refrigeration component 201 is provided with a cold end 202 and a hot end 203, the cold end 202 is arranged adjacent to the air outlet 101, and the hot end 203 is arranged adjacent to the air inlet 100, the cold end 202 and the hot end 203 are components of the refrigeration component 201, the cold end 202 and the hot end 203 are respectively arranged at one end adjacent to the air inlet 100 and the air outlet 101, and the hot end 203 is connected to the energy storage component.

[0036] Among them, the energy storage component can be a heat storage component. It can be understood that when the cold end 202 is cooling, the hot end 203 will generate heat. At this time, the heat can be passed into the heat storage component for storage, thereby improving the cooling effect of the cold end 202. Moreover, when the heat exchange component 20 needs to heat, the heat stored in the heat storage component can also be dissipated, thereby improving the heating effect of the heat exchange component 20.

[0037] In addition, Figure 1 and Figure 2 As shown, the seat headrest 1 also includes: a duct member 30, which is connected between the cooling member 201 and the air outlet 101 to form an outlet duct. The duct member 30 can mainly adjust the air flow and send the low-temperature or high-temperature airflow to the corresponding area. The duct member 30 is connected between the cooling member 201 and the air outlet 101 to form an outlet duct. One end of the duct member 30 is connected to the cooling member 201, and the other end is connected to the air outlet 101. An outlet duct is formed between the cooling member 201 and the air outlet 101, so that the low-temperature or high-temperature airflow can be sent to the corresponding area.

[0038] It should be noted that if Figure 1 and Figure 2 As shown, the air outlet 101 includes: a first air outlet 102 and a second air outlet 103. The first air outlet 102 is arranged opposite to the front of the seat, and the second air outlet 103 is arranged opposite to the rear of the seat. The first air outlet 102 and the second air outlet 103 are components of the air outlet 101, and both can play the role of air outlet. The first air outlet 102 and the second air outlet 103 can blow the internal air out of the seat headrest 1, so as to achieve the temperature change of the seat. The first air outlet 102 is arranged opposite to the front of the seat, and the second air outlet 103 is arranged opposite to the rear of the seat. The first air outlet 102 and the second air outlet 103 are arranged opposite to the front and rear of the seat respectively. Through the first air outlet 102 and the second air outlet 103, the internal air is blown out of the seat headrest 1 to achieve the air temperature change, and the temperature change area is more accurate. Among them, the first air outlet 102 and the second air outlet 103 are not limited to the area in front of the seat and behind the seat where there are people, and can also blow obliquely.

[0039] In addition, if Figure 1 and Figure 2 As shown, the seat headrest 1 also includes: a first air guide 40 and a second air guide 50, the first air guide 40 can be opened and closed at the first air outlet 102, and the second air guide 50 can be opened and closed at the second air outlet 103.

Among them, the first air guide 40 and the second air guide 50 can decide to open the first air guide 40 or the second air guide 50 according to user needs, or open them at the same time. The first air guide member 40 and the second air guide member 50 may be blades in the form of louvers.

[0040] Optionally, the seat headrest 1 further includes: a temperature sensor, which is arranged at the air inlet 100 and / or the air outlet 101. The temperature sensor can be mainly used to detect and feedback temperature data, and the temperature sensor is arranged at the air inlet 100 and / or the air outlet 101. The temperature sensor can be arranged at the air inlet 100 or the air outlet 101, and can also be arranged at the air inlet 100 and the air outlet 101 respectively.

[0041] Specifically, Figure 1 and Figure 2As shown, the seat headrest 1 further includes: an air suction member 60, which is arranged in the surrounding member 10, and the air suction member 60 is arranged opposite to the air inlet 100.

When the suction fan 40 starts working, a large amount of air is introduced into the air suction member 60 through the air inlet 100. Among them, the air suction member 60 can be a blower.

[0042] Of course, if Figure 1 and Figure 2 As shown, the seat headrest 1 further includes: a fixing member 70, the fixing member 70 is arranged on the inner wall of the surrounding member 10, and the air suction member 60 is arranged on the fixing member 70.

[0043] like Figure 1 and Figure 2 As shown, the heating and cooling process of the seat headrest 1 is as follows: when the person in front of or behind the seat in the car has a heating demand, the function is turned on: the air suction member 60 and the heating member 200 start working, a large amount of air is introduced into the air suction member 60 through the air inlet 100, and after absorbing the heat of the heating member 200, the temperature rises and flows through the slit area formed by the Tesla valve structure, and then passes through the air duct member 30, reaches the first air guide member 40 and the second air guide member 50, and the air supply direction is controlled by the air supply angle fixed by the first air outlet 102 and the second air outlet 103, and blows out of the headrest to achieve air conditioning.
