[0038] The specific implementation of the present invention will be further explained in detail below by describing the optimal embodiment with reference to the accompanying drawings.

[0039] A ventilated headrest assembly includes a headrest main body, wherein a ventilation mechanism 4 is arranged inside the headrest main body; the present invention provides the headrest with a ventilation function by installing the ventilation mechanism 4 inside the headrest, thereby facilitating air blowing and cooling of the head of an occupant and improving the comfort of the head area of ​​the occupant in the vehicle.

[0040] The ventilated headrest assembly disclosed in the present invention mainly includes a headrest body, which is the main structure of the headrest assembly. In the present invention, a ventilation mechanism 4 is provided in the headrest body; the ventilation mechanism 4 is mainly used for air supply, so as to facilitate the head blowing operation of passengers in the headrest body area.

[0041] The headrest body described in the present invention includes a headrest body; the headrest body is the main structure of the headrest body, which is convenient for the occupant to lean his head on during subsequent use, and a ventilation channel 11 is provided on the headrest body described in the present invention; the ventilation channel 11 mainly plays a connecting role, facilitating the gas blown out by the ventilation mechanism 4 to pass through the headrest body to blow air to the occupant's head.

[0042] At the same time, in the present invention, the ventilation mechanism 4 is connected to the headrest body; the ventilation mechanism 4 can supply air to the ventilation channel 11; the types of ventilation mechanisms 4 are relatively large, and the ventilation mechanism 4 is detachably connected to the headrest body. The ventilation mechanism 4 can select a motor plus a fan, or it can be a conventional ventilation pump structure. After the mechanism is started, gas can be blown out, which is convenient for blowing the main area of ​​the headrest.

[0043] Furthermore, the headrest body described in the present invention includes a headrest frame 3 and a foam matrix connected to the headrest frame 3; the headrest frame 3 plays a good supporting role, ensuring the overall structural strength of the headrest body, and the foam matrix is ​​made of soft material as a whole, which can provide soft support for the head of the occupant and ensure the riding comfort of the occupant.

[0044] In the present invention, the ventilation mechanism 4 is arranged on the headrest frame 3. Such an arrangement facilitates the installation and arrangement of the ventilation mechanism 4 on the headrest body.

[0045] At the same time, in the present invention, the foaming substrate and the ventilation mechanism 4 are arranged on opposite sides of the headrest frame 3; the headrest frame 3 is provided with ventilation holes 31; the ventilation channel 11 on the foaming substrate, and the ventilation holes 31 are connected with the ventilation channel 11; the gas provided by the ventilation mechanism 4 passes through the ventilation holes 31 and enters the ventilation channel 11 of the foaming substrate, and the gas can be discharged through the channel, so that the gas passes through the headrest body and blows to the head of the occupant.

[0046] Furthermore, the foaming base in the present invention includes a headrest base 2 and a headrest foam 1. The headrest base 2 and the headrest foam 1 can be made of foam material. The headrest base 2 is an arc-shaped block structure as a whole, and the headrest foam 1 is a rectangular block structure. Such a setting is convenient for contact with the head of the occupant, ensuring the contact area between the foaming base and the head of the occupant, and ensuring the comfort of the occupant's head.

[0047] In addition, in the present invention, the ventilation channel 11 is arranged on the headrest foam body 1, and the headrest foam body 1 is connected to the headrest frame 3 through the headrest base 2; a connecting through hole 21 is provided on the headrest base 2; the connecting through hole 21 is connected with the ventilation hole 31; in the present invention, based on the above design, the connection between the headrest foam body 1, the headrest base 2 and the headrest frame 3 is facilitated. During the actual connection, the headrest base 2 is fixed on the headrest frame 3, and the connection method between the two is various, which can be selected according to needs, such as gluing and the like. In addition, in the present invention, the connecting through hole 21 and the ventilation hole 31 are arranged relative to each other, which facilitates the gas supplied by the subsequent ventilation mechanism 4 to enter the ventilation channel 11 on the headrest foam body 1; thereby facilitating the subsequent air outlet operation.

[0048] Furthermore, in the present invention, the headrest foam body 1 is embedded in the headrest base 2; the headrest base 2 is provided with an embedded sink groove 22, and the headrest foam body 1 is arranged in the embedded sink groove 22; the embedded sink groove 22 provided on the headrest base 2 of the present invention plays a storage role, which facilitates the placement and arrangement of the headrest foam body 1 on the headrest base 2. In addition, in the present invention, the embedded sink groove 22 is located in the middle area of ​​the headrest base 2; so that the inner side wall of the embedded sink groove 22 can limit the circumferential position of the headrest foam body 1, and in the present invention, the headrest foam body 1 can be bonded to the headrest base 2 by glue; based on such a setting, the stability of the headrest foam body 1 in the headrest base 2 is guaranteed.

[0049] Furthermore, in the present invention, the ventilation channel 11 includes an air duct groove 101 and a through hole group 102 arranged on the headrest foam body 1; the air duct groove 101 and the through hole group 102 are connected to each other; the through hole group 102 is arranged on the side of the headrest foam body 1 away from the headrest base 2, that is, when used subsequently, it is arranged on the side close to the occupant, and the air duct groove 101 is close to the side of the headrest base 2. When used subsequently, the ventilation mechanism 4 supplies gas to the air duct groove 101, and the gas then flows from the air duct groove 101 to the through hole group 102, and then is discharged to the outside through the through hole group 102 to blow on the occupant's head, thereby realizing ventilation and cooling of the occupant's head.

[0050] In the present invention, the depth of the air duct groove 101 is less than the thickness of the headrest foam body 1; such a configuration makes the air duct groove 101 equivalent to being disposed on one side of the headrest foam body 1, so that the flatness of the headrest foam body 1 close to the passenger side can be ensured as much as possible, thereby ensuring the comfort of the passenger.

[0051] In addition, the through hole group 102 in the present invention includes a plurality of single through holes 113, each of which extends from the air duct groove 101 on the headrest foam body 1 to a side away from the air duct groove 101; the plurality of single through holes 113 ensure the ventilation of the headrest foam body 1, and the present invention can ensure that the gas blown out by the ventilation mechanism 4 can pass through and blow to the head area of ​​the occupant through the coordinated use of the air duct groove 101 and the plurality of single through holes 113, thereby improving the riding comfort of the occupant.

[0052] Furthermore, the air duct sink 101 in the present invention includes a plurality of spaced-apart, parallel-distributed single sinks 111, the single sinks 111 being a part of the air duct sink 101, the single sinks 111 being inclined, and two or more adjacent single sinks 111 being connected by at least one connecting sink 112; such a setting enables the headrest foam body 1 to form a grid structure close to the foaming substrate side, which is convenient for the subsequent gas circulation, and in addition, the connecting sink 112 plays a connecting role, and when the gas supplied by the ventilation mechanism 4 enters one or more single sinks 111, it can be diffused through the connecting sink 112, and gas is distributed in each single sink 111 as much as possible, and such a setting can increase the wind outlet area of ​​the headrest, which is beneficial to blowing multiple areas of the occupant's head, and realizing cooling operations in more areas of the occupant's head.

[0053] In the present invention, the single body sink 111 is arranged at an angle of 45 degrees to the horizontal plane, and the connecting sink 112 is arranged to intersect with the single body sink 111; it is generally required that the connecting sink 112 and the single body sink 111 are arranged perpendicular to each other. Such an arrangement can achieve the connection between the single body sinks 111 at the shortest distance. At the same time, at the intersection of the connecting sink and the single body sink 111, it is required to use an arc surface transition. Such an arrangement can reduce the running resistance of the gas in the air duct sink 101, which is beneficial to ensure the diffusion range of the gas in the headrest body.

[0054] Furthermore, in the present invention, a wind-blocking layer 6 is provided on the side of the headrest foam body 1 close to the headrest base body 2; in the present invention, the wind-blocking layer 6 plays a covering and blocking role, and in subsequent use, it is mainly covered in the air duct groove 101 to avoid problems such as air leakage on the side of the air duct groove 101 close to the headrest base body 2; in the present invention, the wind-blocking layer 6 can be made of a non-woven fabric layer; the wind-blocking layer 6 is attached to the headrest foam body 1; the two can be connected by gluing or the like; in the present invention, the wind-blocking layer 6 covers the air duct groove 101, so that the air duct groove 101 is equivalent to an internal trough structure, which is convenient for regional limitation of the gas entering the headrest foam body 1 and ensuring the air output of the headrest.

[0055] In addition, in the present invention, the wind-blocking layer 6 is provided with ventilation holes 61 ; the ventilation holes 61 , the connecting holes 21 and the ventilation holes 31 are connected in sequence; such a configuration facilitates the gas supplied by the ventilation mechanism 4 to enter the headrest foam body 1 .

[0056] Furthermore, the headrest frame 3 in the present invention is a plastic frame; the provision of the plastic frame can reduce the overall weight of the headrest body while ensuring the headrest body.

[0057] The headrest body described in the present invention also includes a headrest rear decorative cover 5; the headrest rear decorative cover 5 is hollow to form a placement cavity; the headrest rear decorative cover 5 plays a shielding and protective role, and at the same time, an internal cavity can be formed to facilitate the placement of the headrest body; the headrest rear decorative cover 5 described in the present invention is connected to the headrest frame 3; the two can be connected by bolts or by snap-on connection.

[0058] Furthermore, in the present invention, the ventilation mechanism 4 includes a ventilation pump, and the operation of the ventilation pump can supply air to the headrest body, and the ventilation pump includes a pump housing, and the setting of the pump housing facilitates the installation of the ventilation pump on the headrest frame 3.

[0059] In addition, in the present invention, the ventilation pump is connected to the headrest frame 3 through a fastening component; the provision of the fastening component facilitates the connection between the ventilation pump and the headrest frame 3. Specifically, in the present invention, the fastening component includes a support column provided on the headrest frame 3; the pump housing is overlapped on the support column; and subsequently, the pump housing is connected to the support column by bolts passing through the pump housing. Such a provision facilitates the installation and use of the ventilation pump on the headrest frame 3.

[0060] In addition, the ventilated headrest assembly described in the present invention includes two ventilation mechanisms 4, and the two ventilation mechanisms 4 are distributed at intervals on the headrest frame 3, and the ventilation pumps in the two ventilation mechanisms 4 are connected by the same wiring harness assembly 41; such a configuration can reduce the use of the wiring harness assembly 41 while ensuring the air supply. The two ventilation mechanisms 4 disclosed in the present invention are symmetrically arranged on the headrest frame 3, and the wiring harness assembly 41 is arranged on the headrest frame 3 through wiring harness buckles; the headrest frame 3 of the present invention has an arc-shaped structure as a whole, so the two ventilation mechanisms 4 are arranged at the upper end of the headrest frame 3, and the air outlet directions of the two ventilation mechanisms 4 are arranged to intersect, and such a configuration can better ensure the diffusion of gas in the air duct sink 101.

[0061] A seat assembly comprises the ventilated headrest assembly. Specific embodiment:

[0063] The ventilated headrest assembly disclosed in the present invention mainly comprises a headrest foam body 1, a headrest base body 2, a headrest frame 3, a ventilation mechanism 4 and a headrest rear decorative cover 5; the headrest foam body 1, the headrest base body 2, the headrest frame 3, the ventilation mechanism 4 and the headrest rear decorative cover 5 are connected in sequence.

[0064] The ventilated headrest assembly disclosed in the present invention can provide a ventilation system and a comfortable pattern foaming structure in addition to normal adjustment without affecting the normal function of the headrest, thereby increasing the comfort of the headrest area.

[0065] The size of this headrest is similar to that of a conventional headrest, and the setting of the ventilation mechanism 4 can improve the comfort and experience of seat use.

[0066] In the present invention, the headrest foam body 1 and the headrest base 2 are mainly made of foam material, and the headrest frame 3 is mainly supported by plastic. Generally, high-strength plastic material is selected, which has the characteristics of lightness and high strength; the headrest frame 3 is required to be able to effectively bear the headrest and its accessories to ensure structural stability.

[0067] In the present invention, the headrest foam body 1 and the headrest base 2 are made of foam material; in the present invention, the texture on the headrest foam body 1 can adopt various shapes, such as wave shape, grid shape, honeycomb shape, etc., and the ventilation channel 11 is arranged by cleverly designing these textures, and different textures can be adopted according to different shapes.

[0068] The grid-shaped pattern disclosed in the present invention is mainly formed by ventilation channels 11, which are formed by the intersection of multiple single grooves 111 and connecting grooves 112. The grid-shaped pattern forms multiple small channels, which increases the air circulation speed and further improves the heat dissipation effect. The foaming of the pattern helps to reduce the pressure point between the head and the headrest, increase the intrusion amount of the occupant's head and improve comfort.

[0069] The mesh pattern also has the following characteristics:

[0070] 1. Significant ventilation effect: The grid-shaped pattern forms an effective air circulation path through the staggered arrangement of multiple small channels; hot air can be quickly discharged through these small channels to achieve efficient heat dissipation.

[0071] 2. Uniform pressure distribution: The grid-shaped structure can evenly disperse the head pressure, reduce single-point pressure, and improve riding comfort; uniform pressure distribution can also reduce fatigue caused by long-term riding;

[0072] 3. High structural strength: The staggered structure of the grid-shaped pattern has high strength and stability, which can provide sufficient support while ensuring ventilation effect, thereby enhancing the overall durability of the headrest.

[0073] Adapts to various head shapes: The grid-shaped pattern can adaptively adjust according to different head shapes, providing better fit and support, further improving the comfort of the occupants.

[0074] Compared with other texture shapes:

[0075] Wave pattern: Although the wave pattern has certain advantages in ventilation and comfort, it is not as good as the grid pattern in terms of uniform pressure distribution and structural strength. In addition, the manufacturing process of the wave pattern is relatively complicated, which increases the cost.

[0076] Honeycomb pattern: Honeycomb pattern has outstanding performance in strength and lightness, but its complex structural design may increase manufacturing difficulty and cost. At the same time, honeycomb pattern is slightly inferior to grid pattern in terms of uniform pressure distribution.

[0077] Taking all the above factors into consideration, choosing a grid-shaped pattern as the preferred option can not only significantly improve the ventilation effect and ride comfort, but also ensure the structural strength of the headrest and the controllability of manufacturing costs. It is an ideal choice.

[0078] In addition, since the ventilation channel 11 is relatively wide, the present invention also requires that a wind-blocking layer 6 be pasted on the headrest foam body 1; the wind-blocking layer 6 is mainly non-woven fabric; when used, the non-woven fabric is pasted on the headrest foam body 1 to close the ventilation channel 11 to prevent air leakage. When the headrest foam body 1 is installed, the two reserved 40mm ventilation holes 61 are aligned with the ventilation holes 31 on the headrest frame 3; specifically, the non-woven fabric is required to open two 40mm diameter circular ventilation holes 61 at the position of the ventilation mechanism 4.

[0079] Ventilation mechanism 4: a small air suction mechanism is built in; the mechanism is fastened to the headrest plastic with screws, and has the characteristics of low noise and high efficiency; the ventilation mechanism 4 is connected to the seat power supply through a wiring harness, and the user can control the ventilation effect through a switch.

[0080] During the specific installation, the headrest frame 3 is first assembled with the ventilation mechanism 4 and the wiring harness to form a first small assembly, the non-woven fabric and the headrest foam 1 are connected, and then glued and installed on the headrest base 2 to form a second small assembly, and then the first small assembly and the second small assembly, the face cover and the headrest rear trim cover 5 are assembled into a headrest assembly, the headrest is installed on the seat and connected to the wiring harness, and the occupant starts the ventilation mechanism 4 through the switch to start it for use.

[0081] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
