[0047] In this embodiment, the central headrest component 10 of the headrest 100 includes a central cover 11, a central foam 12, and a central cover plate 13, wherein the central cover 11, the central foam 12, and the central cover plate 13 are arranged sequentially from the front to the rear of the headrest and are connected. Specifically, the central foam 12 is fixed to the central cover plate 13 via the central cover 11. The side wing headrest component 20 of the headrest 100 includes a left wing cover 21, a right wing cover 24, a left wing foam 22, a right wing foam 25, a left wing cover plate 23, and a right wing cover plate 26, wherein the left wing cover 21 and the right wing cover 24 are located on the left and right sides of the central cover 11, the left wing foam 22 and the right wing foam 25 are located on the left and right sides of the central foam 12, and the left wing cover plate 23 and the right wing cover plate 26 are located on the left and right sides of the central cover plate 13, respectively. The right wing foam 25 is fixed to the right wing cover plate 26 via the right wing cover 24. The left wing foam 22 is fixed to the left wing cover plate 23 by the left wing surface sleeve 21.

[0048] In this embodiment, the headrest body 30 of the headrest 100 further includes a headrest middle cover 31, a headrest back cover 32, a headrest back foam 33, and a headrest back cover 34. The headrest middle cover 31, headrest back cover 32, headrest back foam 33, and headrest back cover 34 are arranged sequentially from the front to the rear of the headrest 100 and are connected. The connecting assembly 40 is connected to the headrest middle cover 31 and the middle headrest component 10. The left wing cover 23 and the right wing cover 26 are fixed to the headrest middle cover 31. The headrest back foam 33 is fixed to the headrest back cover 32 via the headrest back cover 34, and then the headrest back cover 32 is fixed to the headrest middle cover 31.

[0049] In this embodiment, the headrest 100 also includes two headrest rods 61, which are connected to the headrest back cover 32 via headrest positioning pins 62.

[0050] In this embodiment, the connecting assembly 40 includes a middle panel 44, a gear 42, and a rotating member 43. The middle panel 44 is disposed between the middle headrest component 10 and the headrest body 30, and is connected to the middle headrest component 10. A rack structure 451 is provided on the side of the middle panel 44 facing the rear of the seat, and the gear 42 is disposed on the side of the middle panel 44 facing the rear of the seat and meshes with the rack structure 451. The rotating member 43 is rotatably connected to the headrest body 30, and the gear 42 is sleeved on the rotating member 43. The rotating member 43 is configured to protrude to the outer side of the headrest 100 so that it rotates when operated, thereby driving the gear 42 to rotate, thereby driving the middle panel 44 to move the middle headrest component 10 vertically. See details below. Figure 2 Here, the connecting assembly 40 also includes an intermediate connecting plate 45, which is fixed to the intermediate panel 44 by four screws. A rack structure 451 is located on the side of the intermediate connecting plate 45 facing away from the intermediate panel 44. A knob 41 is provided on one end of the rotating member 43 protruding to the outside of the headrest 100. The occupant can rotate the knob 41 to drive the rotating member 43 to rotate the gear 42, causing the rack structure 451 to move up and down. This, in turn, causes the intermediate connecting plate 45 to move the intermediate panel 44 up and down, ultimately moving the intermediate headrest component 10 up and down. The rack structure 451, gear 42, and rotating member 43 are all hidden inside the headrest 100; the occupant can only see the knob 41 from the outside, thus improving the aesthetics of the headrest 100. In other embodiments, the up and down movement of the intermediate headrest component 10 can also be achieved through other structures. The knob 41 is installed after all components of the headrest 100 are installed.

[0051] In this embodiment, see details. Figure 2 , Figure 2 This is the back structure of the headrest cover 31. The headrest cover 31 of the headrest body 30 is connected to the middle panel 44, and a through groove is provided in the middle position, which is opposite to the rack structure 451. The gear 42 is located on the side of the headrest cover 31 facing the back of the seat and is located at the through groove to mesh with the rack structure 451. The rotating member 43 is rotatably connected to the headrest cover 31. Here, the width of the rack structure 451 is the same as the length of the gear 42, and the size of the through groove is set according to the width of the rack structure 451. The width of the through groove can be set to be the same as the width of the rack structure 451, or it can be set to be greater than the width of the rack structure 451, so as not to affect the up and down movement of the rack structure 451.

[0052] In this embodiment, the middle panel 44 has at least one protruding limiting portion 442 on the side facing the rear of the seat. The headrest cover 31 has at least one vertically extending guide groove 311, so that the limiting portion 442 engages with the guide groove 311, thereby guiding and limiting the middle panel 44 during its vertical movement. See details below. Figure 3 The dimensions of the guide groove 311 are set according to the dimensions of the limiting part 442. It is necessary to ensure that the limiting part 442 can pass through the guide groove 311 and move up and down along it. The length and vertical thickness of the limiting part 442 can be set according to specific design requirements. When the middle panel 44 moves to the point where the limiting part 442 abuts against the top of the guide groove 311, the middle panel 44 is at its highest point. When the middle panel 44 moves to the point where the limiting part 442 abuts against the bottom of the guide groove 311, the middle panel 44 is at its lowest point. The travel distance of the middle panel 44 is the length of the guide groove 311 minus the vertical thickness of the limiting part 442. The longer the guide groove 311, the longer the travel distance of the middle panel 44; the shorter the guide groove 311, the shorter the travel distance of the middle panel 44. The middle headrest component 10 moves up and down with the middle panel 44. In this embodiment, the gear 42 and the rotating component 43 are located near the bottom of the guide groove 311.

[0053] In this embodiment, by setting a guide groove 311, the guide groove 311 can limit the left and right movement of the middle panel 44 and restrict the vertical movement of the middle panel 44, thereby improving the stability of the movement of the middle panel 44 and thus improving the stability of the movement of the middle headrest component 10. By limiting the movement of the middle panel 44 and the middle headrest component 10, the situation where the middle panel 44 exceeds the movement range and causes the middle headrest component 10 to fall off the headrest can be avoided.

[0054] In this embodiment, there are two limiting parts 442 and two guide grooves 311. Each limiting part 442 corresponds to one guide groove 311, and the two guide grooves 311 are located on opposite sides of the through groove. See [reference needed] Figure 2 Here, the vertical length of the rack structure 451 can be set to be greater than the vertical length of the guide groove 311.

[0055] In this embodiment, the headrest 100 further includes at least one end cap 70, each end cap 70 being arranged correspondingly to a limiting portion 442. The end cap 70 is disposed on the side of the headrest middle cover 31 away from the middle panel 44, so as to connect with the limiting portion 442 when the limiting portion 442 passes through the corresponding guide groove 311, thereby connecting the middle panel 44 and the headrest middle cover 31. Here, the limiting portion 442 of the middle panel 44 is first passed through the corresponding guide groove 311, and then the end cap 70 is installed from the back of the headrest middle cover 31 at the end of the limiting portion 442. By providing the end cap 70, this embodiment can prevent the limiting portion 442 from sliding out of the guide groove 311, and allow the middle cover 13 and the headrest middle cover 31 to slide together, preventing them from separating.

[0056] This embodiment cleverly utilizes the gear 42 and rack structure 451. The rotation of the gear 42 drives the rack structure 451 to move up and down, thereby moving the middle panel 44 up and down, which in turn moves the middle headrest component 10 up and down. This arrangement can meet the different head height requirements of passengers, providing effective support and improving passenger comfort. (See also...) Figure 7 .

[0057] In a preferred embodiment, the center headrest component 10 includes a center cover 13 disposed on the side of the center panel 44 facing the front of the seat and rotatably connected to the center panel 44 so as to flip relative to the center panel 44 towards the front of the seat when operated. See [reference needed] Figure 6 .

[0058] In this embodiment, the connecting assembly 40 further includes a hinge shaft 50, which is disposed on the top of the intermediate cover plate 13 and is used to connect the intermediate panel 44 and the intermediate cover plate 13, so that the intermediate panel 44 and the intermediate cover plate 13 are rotatably connected. A damper is provided inside the hinge shaft 50. (See [reference]) Figure 4 and Figure 5 , Figure 5 This is a schematic diagram after removing the middle panel 44. In this embodiment, the hinge pivot 50 has a damper positioning function, allowing the middle headrest component 10 to rotate to the desired position for the passenger. In this embodiment, the middle headrest component 10 can be adjusted by simply rotating it manually. Here, a connecting portion 441 is provided at the top of the middle panel 44, and the hinge pivot 50 is located inside the connecting portion 441.

[0059] This embodiment also provides a seat, which includes the headrest 100 described above. Details regarding the headrest 100 will not be provided here.

[0060] This embodiment also provides a vehicle that includes the aforementioned seats. Details regarding the seats will not be elaborated upon here.

[0061] This embodiment provides a new headrest 100 that allows the middle headrest component 10 to be adjusted up and down along the seat and folded towards the front of the seat, meeting the comfort requirements of various passengers and various scenarios. Through the adjustment of the middle headrest component 10, this embodiment can effectively support the head of the passenger for normal sitting, resting or sleeping, effectively improving the comfort of driving and resting.
