[0002] As living standards continue to improve, consumers are paying more and more attention to the car riding experience, and the cooling performance of car seats is receiving increasing attention, becoming one of the key factors consumers consider when choosing a car.

[0003] Traditional seats use a suction cooling method to cool the body. The principle is to have air inlets on the seat surface, and a fan draws air in through these inlets, creating an airflow. This airflow then passes through the seat's interior and exits from the base or backrest, carrying away heat generated by the body. However, this suction cooling method has relatively low air pressure, limiting the amount of heat it can remove and resulting in poor cooling effectiveness. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a seat assembly, a vehicle seat, and a vehicle, which can improve the cooling effect of the seat assembly.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0041] like Figure 1 As shown, this utility model embodiment provides a seat assembly 100, which can be applied to vehicles, furniture seats, or commercial seats.

[0042] Please combine Figure 2The seat assembly 100 includes a backing structure 10 and a fan 20. The backing structure 10 is provided with a first vent 101 and a second vent 102. The air inlet of the fan 20 is connected to the first vent 101, and the air outlet of the fan 20 is connected to the second vent 102. The fan 20 is used to draw airflow from the backing structure 10 toward the side where the passenger is located through the first vent 101, and to blow airflow out toward the backing structure 10 toward the side where the passenger is located through the second vent 102.

[0043] When the fan 20 is started, the fan 20 draws air from the first vent 101, creating a negative pressure in the first vent 101. At this time, the air outside the first vent 101 is drawn in by the negative pressure and forms an airflow that enters the first vent 101. The airflow entering the first vent 101 is transported to the second vent 102 by the fan 20 and blown out towards the side of the structure 10 toward the passenger through the second vent 102. In this way, an airflow path is formed that can cool the passenger.

[0044] In this embodiment of the invention, by providing a first vent 101 and a second vent 102 on the abutment structure 10, when the fan 20 draws air from the first vent 101, the air forms a drawn-out airflow outside the first vent 101, thereby bringing the heat generated by the passenger into the first vent 101, thus achieving the first cooling effect on the passenger; furthermore, under the suction of the fan 20, the airflow in the first vent 101 is blown through the second vent 102 towards the side of the abutment structure 10 where the passenger is located, thereby promoting air circulation on the side of the abutment structure 10 where the passenger is located and accelerating the evaporation of the passenger's sweat, thus achieving the second cooling effect on the passenger and improving the passenger's comfort with the airflow. This utility model embodiment uses the first ventilation port 101 and the second ventilation port 102 to draw in and blow airflow to the side of the passenger abutting the structure 10, which can achieve a good cooling effect, meet the requirements of rapid cooling, improve the comfort of the passenger, and realize the reuse of the airflow drawn in by the first ventilation port 101, thereby improving the utilization rate of airflow and saving energy and protecting the environment.

[0045] To prevent passengers from obstructing the second air vent 102 on the abutment structure 10 when sitting on the seat assembly 100, such as Figure 1As shown, in some embodiments, the abutment structure 10 includes an abutment body 11 and side wings 12. The abutment body 11 is the part that contacts the passenger, and the side wings 12 are disposed around the periphery of the abutment body 11. A first vent 101 is located on the abutment body 11, and a second vent 102 is located on the side wings 12. The abutment body 11 is mainly used to provide forward abutment for the passenger, that is, it is mainly used to abut against the passenger's buttocks or back, etc. The side wings 12 are mainly used to provide lateral abutment for the passenger, that is, it is mainly used to abut against the side of the passenger's thighs or arms, etc. Normally, when a passenger sits on the seat assembly 100, their body will mainly only abut against the abutment body 11, and rarely directly against the side wings 12.

[0046] In this embodiment, the first vent 101 on the main body 11 and the second vent 102 on the side wing 12 can jointly generate airflow and cool the passenger under the action of the fan 20. By setting the second vent 102 on the side wing 12, which is located around the main body 11, the passenger can avoid blocking the second vent 102 on the side wing 12 and affecting the airflow to a certain extent. This ensures the effective airflow at the side wing 12, which is beneficial to improving the passenger's feeling of airflow and ensuring the cooling effect of the seat assembly 100.

[0047] In some embodiments, the side wing 12 includes a first side portion 121, which is disposed on at least one side of the body 11 in the width direction and extends along the length direction of the body 11, and the first side portion 121 is provided with a plurality of second vents 102 at intervals.

[0048] The width direction of the abutment body 11 refers to the direction in which the abutment body 11 is parallel to the left-right direction of the passenger when the passenger abuts against the abutment body 11, that is, the first side portion 121 is located on the left and / or right side of the abutment body 11; when the abutment body 11 is used to abut against the passenger's buttocks, the length direction of the abutment body 11 refers to the direction in which the abutment body 11 is parallel to the passenger's front-back direction; when the abutment body 11 is used to abut against the passenger's back, the length direction of the abutment body 11 refers to the direction in which the abutment body 11 is parallel to the passenger's height direction; the width direction and the length direction of the abutment body 11 are perpendicular.

[0049] In this embodiment, by positioning the first side portion 121 of the side wing 12 on at least one side of the body 11 in the width direction, the obstruction of the second vent 102 on the first side portion 121 by the passenger can be largely avoided, thus ensuring effective airflow at the side wing 12. When a passenger sits on the seat assembly 100, the second vent 102 on the first side portion 121 can generate airflow for the passenger on at least one side of the body 11 in the width direction, thereby achieving a better cooling effect.

[0050] By extending the first side portion 121 along the length direction of the main body 11 and providing multiple second vents 102 at intervals on the first side portion 121, the first side portion 121 can have a large air outlet area. The airflow sent from each of the second vents 102 on the first side portion 121 can cover a large area of ​​the passenger, and the airflow is relatively stable and uniform, which is conducive to improving the cooling effect on the passenger.

[0051] In some embodiments, there are two first side portions 121, which are respectively disposed on both sides of the body 11 in the width direction.

[0052] In some embodiments, the side wing 12 further includes a second side portion 122, which is disposed on at least one side of the abutting body 11 in the length direction and extends along the width direction of the abutting body 11, and the second side portion 122 is provided with a plurality of second vents 102 at intervals.

[0053] In this embodiment, by adding a second side portion 122 and positioning it on at least one side of the body 11 along its length, the obstruction of the second vent 102 on the second side portion 122 by the passenger can be largely avoided, thus ensuring effective airflow at the side wing 12. When a passenger sits on the seat assembly 100, the second vent 102 on the second side portion 122 can generate airflow for the passenger on at least one side of the body 11 along its length, thereby achieving a better cooling effect for the passenger.

[0054] By extending the second side portion 122 along the width direction of the main body 11 and providing multiple second vents 102 at intervals on the second side portion 122, the second side portion 122 can have a large air outlet area. The airflow delivered from each of the second vents 102 on the second side portion 122 can cover a large area of ​​the passenger, and the airflow is relatively stable and uniform, which is conducive to improving the cooling effect on the passenger.

[0055] In some embodiments, the axial extension direction of the first vent 101 intersects the axial extension direction of the second vent 102 on the first side 121. Since the axial extension direction of the first vent 101 disposed on the abutting body 11 is substantially perpendicular to the passenger, that is, the opening of the first vent 101 is perpendicular to the passenger, and since the axial extension direction of the second vent 102 on the first side 121 intersects the axial extension direction of the first vent 101, the opening of the second vent 102 on the first side 121 is also facing the passenger. Thus, airflow can be effectively blown to the passenger through the second vent 102 on the first side 121, ensuring the airflow blowing effect of the first side 121.

[0056] And / or, the extending direction of the axis of the first vent 101 intersects the extending direction of the axis of the second vent 102 on the second side 122. Since the axial extending direction of the first vent 101 provided on the abutment body 11 is substantially perpendicular to the passenger, that is, the opening of the first vent 101 is perpendicular to the passenger, when the extending direction of the axis of the second vent 102 on the second side 122 intersects the extending direction of the axis of the first vent 101, the opening of the second vent 102 on the second side 122 is also facing the passenger. In this way, airflow can be effectively blown to the passenger through the second vent 102 on the first side 121, ensuring the airflow blowing effect of the first side 121.

[0057] When the abutment body 11 is used to abut against the buttocks of a passenger, the first side portion 121 is located on the left and / or right side of the passenger's thigh, and the airflow from the second vent 102 on the first side portion 121 can act on the side of the passenger's thigh and other parts. When the abutment body 11 is used to abut against the back of a passenger, the first side portion 121 is located on the left and / or right side of the passenger's upper body, and the airflow from the second vent 102 on the first side portion 121 can act on the side of the passenger's upper body and other parts.

[0058] When the abutment body 11 is used to abut against the buttocks of the passenger, the second side 122 is located on the front and / or rear side of the lower body of the passenger. When the second side 122 is located on the front side of the lower body of the passenger, the airflow delivered by the second vent 102 on the second side 122 can act on the back of the passenger's knees or calves. When the second side 122 is located on the rear side of the lower body of the passenger, the airflow delivered by the second vent 102 on the second side 122 can act on the lower back or buttocks of the passenger. When the abutment body 11 is used to abut against the back of the passenger, the second side 122 is located on the upper and / or lower side of the passenger's upper body. When the second side 122 is located on the upper side of the passenger's upper body, the airflow delivered by the second vent 102 on the second side 122 can act on the passenger's shoulder, neck, or head. When the second side 122 is located on the lower side of the passenger's upper body, the airflow delivered by the second vent 102 on the second side 122 can act on the passenger's lower back or buttocks.

[0059] like Figure 2 As shown, in some embodiments, the seat assembly 100 further includes a first air guide bag 30 and a second air guide bag 40. The first air guide bag 30 connects the first vent 101 and the air inlet of the fan 20, and the second air guide bag 40 connects the second vent 102 and the air outlet of the fan 20. When the fan 20 is working, the first air guide bag 30 draws airflow from the side of the occupant of the support structure 10 through the first vent 101 against the main body 11, and then delivers it to the second air guide bag 40 through the fan 20. The airflow from the second air guide bag 40 is blown to the side of the occupant of the support structure 10 through the second vent 102 of the first side 121 and the second side 122.

[0060] In this embodiment, by setting a first air guide bag 30 between the first vent 101 and the air inlet of the fan 20, and setting a second air guide bag 40 between the second vent 102 and the air outlet of the fan 20, airflow between the first vent 101, the fan 20 and the second vent 102 is achieved. This provides a stable channel for airflow, effectively prevents leakage of airflow during transmission, ensures that airflow can flow between the first vent 101 and the second vent 102 along a predetermined path, and improves the utilization efficiency of airflow.

[0061] In some embodiments, the seat assembly 100 further includes a base 50 and a backrest 60, the base 50 being used to support the buttocks of the occupant and the backrest 60 being used to support the back of the occupant.

[0062] At least one of the base 50 and the backrest 60 is provided with a backing structure 10. The second side 122 is provided on the side of the base 50 near the backrest 60 or on the side of the backrest 60 near the base 50. In this way, the obstruction of the second vent 102 on the second side 122 by the passenger can be largely avoided, thus preventing the airflow from being affected. The airflow delivered by the second vent 102 on the surface of the second side 122 can act on the lower back or buttocks of the passenger.

[0063] In some embodiments, the fan 20 includes a first fan 21 and a second fan 22; the first air guide bag 30 includes a first air guide sub-bag 31 and a second air guide sub-bag 32; the second air guide bag 40 includes a third air guide sub-bag 41 and a fourth air guide sub-bag 42; the first side portion 121 includes a first side portion 1211 and a second side portion 1212; the first vent 101 includes a first vent and a second vent; the second vent 102 includes a third vent and a fourth vent; and the abutment body 11 includes a first abutment body 111 and a second abutment body 111. The body 112 has a first abutment body 111 located on the backrest 60, the first abutment body 111 having a first ventilation opening, a first side portion 1211 located on at least one side of the first abutment body 111 in the width direction, and the first side portion 1211 having a third ventilation opening. The second abutment body 112 is located on the base 50, the second abutment body 112 having a second ventilation opening, the second side portion 1212 located on at least one side of the second abutment body 112 in the width direction, and the second side portion 1212 having a fourth ventilation opening.

[0064] The first air guide bag 31 connects to the first vent and the air inlet of the first fan 21, and the third air guide bag 41 connects to the third vent and the air outlet of the first fan 21. When the first fan 21 is working, the first air guide bag 31 draws airflow from the side of the backrest 60 where the passenger is located through the first vent that abuts against the main body 111, and then delivers it to the third air guide bag 41 through the first fan 21. The airflow in the third air guide bag 41 is blown to the side of the backrest 60 where the passenger is located through the third vent of the first side 1211 and the second side 122.

[0065] The second air guide bag 32 is connected to the second vent and the air inlet of the second fan 22, and the fourth air guide bag 42 is connected to the fourth vent and the air outlet of the second fan 22. When the second fan 22 is working, the second air guide bag 32 draws airflow from the passenger side of the base 50 through the second vent that abuts against the main body 112, and then delivers it to the fourth air guide bag 42 through the second fan 22. The airflow in the fourth air guide bag 42 is then blown to the passenger side of the base 50 through the fourth vent on the second side 1212.

[0066] Through the above settings, both the base 50 and the backrest 60 can form air intake and air outlet areas, drawing in and blowing air towards the passenger side. In this way, the seat assembly 100 can create airflows at different locations to cool the passenger, covering a large area of ​​the passenger, further promoting air circulation on the passenger side, accelerating the evaporation of sweat, improving the cooling effect, meeting the requirements for rapid cooling, improving the passenger's comfort, and saving energy and protecting the environment.
