Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] An embodiment of the present application provides a headrest.

[0024] like Figures 1 to 3 As shown, the headrest includes a support component 1 and a ventilation component 2, an air outlet cavity 111 is formed in the support component 1, the ventilation component 2 is connected to the air outlet cavity 111, an air outlet hole 121 is opened on one side of the support component 1, the air outlet hole 121 is connected to the air outlet cavity 111, and the ventilation component 2 is used to ventilate to the outside of the support component 1 through the air outlet cavity 111 and the air outlet hole 121.

[0025] Please see further Figure 2 and Figure 3 The headrest of the embodiment of the present application is mainly used to be installed on the seat of the vehicle. The support assembly 1 is used to support the head, neck and other parts of the vehicle occupant. Since an air outlet cavity 111 is formed in the support assembly 1, and an air outlet hole 121 connected to the air outlet cavity 111 is opened on the side of the support assembly 1 used to support the occupant. The ventilation assembly 2 passes through the side of the support assembly 1 away from the occupant and is connected to the air outlet cavity 111. The ventilation assembly 2 can ventilate the air outlet cavity 111, and a pressure difference is formed between the air outlet cavity 111 and the external environment of the support assembly 1. The air in the air outlet cavity 111 will pass through the air outlet hole 121 to the outside, that is, blow to the neck and the rear end of the head of the occupant. Since the temperature of the air introduced into the air outlet cavity 111 by the ventilation assembly 2 can be adjusted, the head and neck of the vehicle occupant can be blown through the air outlet hole 121 to achieve temperature adjustment of the head, neck and other parts, thereby improving the comprehensiveness of the air conditioning adjustment function in the vehicle for the temperature adjustment of the occupant's body, and effectively improving the driving and riding comfort of the occupant.

[0026] Optionally, the ventilation component 2 includes a ventilation duct 21, a blowing piece 22 and a temperature regulating piece 23, one end of the ventilation duct 21 is connected to the air outlet cavity 111, and the blowing piece 22 is arranged in the ventilation duct 21; the temperature regulating piece 23 is arranged on the ventilation duct 21, and is used to adjust the temperature of the air in the ventilation duct 21.

[0027] Please see further Figure 1 In this embodiment, the blowing member 22 can be a variety of devices capable of blowing air, such as a positive displacement fan, a turbine fan, and a jet fan. The thermostat 23 can be an air conditioning heating and cooling module. The ventilation duct 21 is a hollow tubular structure, and one end of the ventilation duct 21 penetrates the support assembly 1 and is connected to the air outlet cavity 111. The blowing member 22 can be arranged at one end of the ventilation duct 21 away from the support assembly 1. The thermostat 23 can be arranged on the pipe wall outside the ventilation duct 21, and can also be arranged inside the ventilation duct 21. The air blown into the ventilation duct 21 by the blowing member 22 can be heated or cooled by the thermostat 23, so that the temperature of the occupants can be adjusted whether it is cold or hot, thereby expanding the scope of application.

[0028] Optionally, the ventilation assembly 2 further includes a heat sink 24 , a mounting hole is opened on the ventilation duct 21 , the temperature regulating component 23 is embedded in the mounting hole, and the heat sink 24 is installed on a side of the temperature regulating component 23 away from the ventilation duct 21 .

[0029] Please see further Figure 1 and Figure 3 In this embodiment, the thermostat 23 is embedded in the mounting hole (not shown in the figure), and can be located in the ventilation duct 21 as a whole, or partially located in the ventilation duct 21 and partially located outside the ventilation duct 21. A heat sink 24 is provided on the side of the thermostat 23 facing away from the ventilation duct 21. The heat sink 24 has good thermal conductivity. The heat sink 24 can be made of materials with good thermal conductivity such as aluminum alloy and copper alloy. The heat generated during the operation of the thermostat 23 exchanges heat with the heat sink 24, is transferred to the heat sink 24, and then exchanges heat with the surrounding air through the heat sink 24, and transfers the heat to the outside air, thereby reducing the temperature of the thermostat 23, avoiding the thermostat 23 being at a high operating temperature all the time, and extending the service life of the thermostat 23.

[0030] Optionally, the ventilation assembly 2 further includes a heat dissipation fan 25 , which is installed on a side of the heat dissipation plate 24 away from the temperature adjustment component 23 .

[0031] Please see further Figure 1The cooling fan 25 is arranged on the heat sink 24. After the heat generated during the operation of the temperature control component 23 is transferred to the heat sink 24, the cooling fan 25 starts to work and the blades rotate, so that the air moves along the heat sink 24 toward the outside, forming a higher air flow speed, accelerating the air flow near the heat sink 24, and improving the efficiency of transferring the heat on the heat sink 24 to the outside, thereby improving the heat dissipation effect of the temperature control component 23.

[0032] Optionally, the ventilation duct 21 includes a first connecting section 211, a bending section 212 and a second connecting section 213 connected in sequence, the first connecting section 211 is arranged along a first direction, and the end of the first connecting section 211 away from the bending section 212 is connected to the air outlet cavity 111, the second connecting section 213 is arranged along a second direction, the blowing member 22 is arranged in the second connecting section 213, and the mounting hole is opened on the second connecting section 213, wherein the first direction is different from the second direction.

[0033] Please refer to Figure 1 and Figure 3 In this embodiment, when the headrest is installed on the seat of the vehicle, the first direction is the horizontal direction and the second direction is the vertical direction, that is, the first connecting section 211 is arranged along the horizontal direction and the second connecting section 213 is arranged along the vertical direction. The bending section 212 connects the first connecting section 211 and the second connecting section 213. The arrangement of the bending section 212 can avoid interference between the ventilation duct 21 and the mounting rod on the seat.

[0034] Optionally, the support assembly 1 includes a connecting structure 11 and a supporting structure 12, and an air outlet cavity 111 is provided on the connecting structure 11;

[0035] The supporting structure 12 is installed on a side of the connecting structure 11 facing away from the ventilation assembly 2 , and an air outlet 121 is formed in the supporting structure 12 .

[0036] like Figure 1 As shown, the support assembly 1 includes a connection structure 11 and a support structure 12. The support structure 12 is mounted on the connection structure 11, and an air outlet cavity 111 connected to the ventilation duct 21 is provided on the connection structure 11. An air outlet hole 121 is provided on the support structure 12, and the support structure 12 is used to support the head and neck of the vehicle occupant. When the ventilation assembly 2 is working, air is blown to the occupant through the air outlet hole 121 to adjust the body temperature of the occupant. The support structure 12 can be made of elastic materials such as foam, latex, etc., which can provide a more comfortable support experience for the vehicle occupant.

[0037] Optionally, the support assembly 1 further includes a mesh layer 13, the shape of the mesh layer 13 matches the air outlet cavity 111 and is embedded in the air outlet cavity 111, and the mesh layer 13 is used for guiding air.

[0038] The headrest of the present application is used in a vehicle. Since the space in the vehicle is limited, in order to reduce the space occupied by the headrest, the volume of each structure is as small as possible. Generally speaking, the nozzle area of ​​the ventilation duct 21 will be much smaller than the cross-sectional area of ​​the air outlet cavity 111. Before the grid layer 13 is set, when the ventilation duct 21 blows air into the air outlet cavity 111, since the nozzle area of ​​the ventilation duct 21 is much smaller than the cross-sectional area of ​​the air outlet cavity 111, the air introduced into the air outlet cavity 111 will continue to blow to the outside through the air outlet hole 121 when the space in the air outlet cavity 111 is not filled with the air introduced by the ventilation duct 21. This results in different sizes of wind blown out by the air outlet holes 121 at different positions. The mesh layer 13 of the present embodiment may be a structure having three-dimensional mesh features such as a Miller ventilation layer. After the mesh layer 13 is provided, the ventilation duct 21 ventilates the air outlet cavity 111, and must first pass through the mesh layer 13 filled in the air outlet cavity 111 before reaching the air outlet holes 121. The mesh layer 13 can keep the air outlet volume of each air outlet hole 121 uniform, thereby ensuring the uniformity of the air outlet of the headrest of the present embodiment, and providing a more comfortable experience for the vehicle occupants.

[0039] Optionally, there are multiple air outlet holes 121, and the multiple air outlet holes 121 are arranged in an array on the support structure 12. Figure 1 A plurality of air outlet holes 121 are evenly arranged on the supporting structure 12, further ensuring the air outlet uniformity of the headrest of this embodiment.

[0040] The present application also provides a seat, which includes a seat back 3 and a headrest as described above, wherein the headrest is mounted on the seat back 3, as shown in FIG. Figure 3 As shown, the seat back 3 includes a mounting rod, the "support assembly 1" and the "blowing member 22, the temperature regulating member 23" are respectively located on both sides of the mounting rod, the support assembly 1 is fixed to the mounting rod, one end of the ventilation duct 21 away from the support assembly 1 is fixed to the seat back 3, and the other end is connected to the support assembly 1, and the ventilation duct 21 has a bending section 212 to avoid interference with the mounting rod. Since the technical solution of this embodiment includes all the technical solutions of the above embodiments, it can at least achieve all the technical effects of the above embodiments, which will not be repeated here.

[0041] The embodiment of the present application also provides a vehicle, including the seat as above. Since the technical solution of this embodiment includes all the technical solutions of the above embodiments, it can at least achieve all the technical effects of the above embodiments, which will not be repeated here one by one.
