[0026] It should be noted that the matching gear 33 should be coaxially arranged with the rotating shaft 4, so that the headrest frame 2 can form a swinging action around the rotating shaft 4 when the headrest frame 2 is driven, and the jamming problem caused by different shafts is avoided, and the smoothness of the action of the headrest frame 2 is ensured.

[0027] In some possible implementation manners, the seat frame 1 adopts the structure as shown in Figure 3 . Referring to Figure 3 , the rear side of the seat frame 1 is provided with two extension seats 11 extending rearward and symmetrically located on both sides of the headrest frame 2, the rotating shaft 4 is provided with two rotating shafts 4 and is connected to the two extension seats 11 one by one, and the rotating shaft 4 is connected to the side of the headrest frame 2 and extends outward.

[0028] In the embodiment, the rear side of the seat frame 1 is provided with the extension seat 11, the rotating shaft 4 can be conveniently connected to the extension seat 11, the headrest frame 2 is rotatably connected to the seat frame 1, and the headrest frame 2 can smoothly swing forward and backward. The rotating shaft 4 is arranged at the position close to the rear part of the extension seat 11, that is, the rotating shaft 4 is spaced apart from the seat frame 1 by a certain distance, when the headrest frame 2 swings forward and backward, the headrest frame 2 has a certain distance from the seat frame 1, so that the position interference between the headrest frame 2 and the seat frame 1 is avoided, and the space requirement of adjustment is met.

[0029] In some embodiments, the matching gear 33 can adopt the structure as shown in Figure 2 . Referring to Figure 2The matching gear 33 is a sector gear, and is fixedly connected to the lower portion of the extension base 11 and arranged adjacent to the headrest frame 2.

[0030] In this embodiment, the headrest frame 2 only needs to swing forward and backward within a certain range during adjustment, and therefore the matching gear 33 in the form of a sector gear can meet the action requirement. The matching gear 33 is connected to the lower portion of the extension base 11 and located close to the headrest frame 2, and can cooperate with the driving gear 32 to effectively drive the headrest frame 2.

[0031] In some embodiments, the above-mentioned feature extension base 11 can adopt the structure as shown in Figure 2 . Referring to Figure 2 , the extension base 11 has a weight-reducing cavity 12 opening downward, and a horizontally extending rotating sleeve 13 is provided through the extension base 11, and the rotating shaft 4 is rotatably connected in the rotating sleeve 13.

[0032] In this embodiment, the extension base 11 has a weight-reducing cavity 12 opening downward, which has a good structural weight-reducing effect and facilitates the arrangement of the rotating sleeve 13. The rotating sleeve 13 is arranged in the horizontal direction, i.e., the left-right direction, and is provided through the extension base 11. The rotating shaft 4 is rotatably connected in the rotating sleeve 13 and extends to the side of the central axis of the headrest frame 2. The rotating shaft 4 and the rotating sleeve 13 are rotatably connected, which can reduce the friction formed during the swinging of the headrest frame 2, and improve the smoothness and convenience of the front and rear position adjustment of the headrest frame 2 and the headrest base.

[0033] Specifically, the outer end of the rotating shaft 4 is provided with a limiting end disc 41, which is connected to the outer end of the rotating shaft 4 through a connecting piece.

[0034] In some possible implementations, the above-mentioned feature headrest frame 2 adopts the structure as shown in Figure 3 . Referring to Figure 3 , the headrest frame 2 is provided with a mounting plate 21, the rotating drive 31 is connected to the mounting plate 21, and the rear side of the mounting plate 21 is connected with a transmission wheel set 5 for transmitting power from the driving gear 32 to the matching gear 33.

[0035] In this embodiment, in order to facilitate the structural installation of the rotating drive 31, the driving gear 32 and other components, the mounting plate 21 is arranged on the rear side of the headrest frame 2. The plate surface of the mounting plate 21 extends in the up-down direction, the rotating drive 31 is connected to the rear side of the mounting plate 21, and the driving gear 32 is connected to the output shaft of the rotating drive 31. The main shafts of the two extend in the left-right direction.

[0037] In some embodiments, the transmission wheel set 5 can adopt the structure as shown in Figure 2 . Figure 2 The transmission wheel set 5 comprises a transmission shaft 51, a first gear 52 and a second gear 53. The transmission shaft 51 is rotationally connected to the mounting plate 21 in the horizontal direction. The first gear 52 is sleeved on the middle part of the transmission shaft 51 and is engaged with the driving gear 32. The second gear 53 is arranged at the end of the transmission shaft 51 and is engaged with the matching gear 33.

[0038] In this embodiment, the transmission shaft 51 is arranged at the rear side of the mounting plate 21 through the shaft seat 55 arranged on the mounting plate 21. The shaft seat 55 is provided with two, and the two ends of the transmission shaft 51 are rotationally connected to the shaft seat 55 one by one. The first gear 52 of the transmission wheel set 5 is engaged with the driving gear 32. The first gear 52 transmits power to the second gear 53 through the transmission shaft 51, and then transmits power to the matching gear 33 through the second gear 53, so that the effective transmission of power is realized, and the arrangement of the structure is facilitated.

[0039] In some embodiments, the second gear 53 and the matching gear 33 can adopt the structure as shown in Figure 2 . Figure 2 The second gear 53 and the matching gear 33 are respectively provided with two. The two second gears 53 are connected to the two ends of the transmission shaft 51 one by one, and the two matching gears 33 are engaged with the two second gears 53 one by one.

[0040] In this embodiment, the first gear 52 is arranged in the middle part of the transmission shaft 51 and is engaged with the driving gear 32. The second gear 53 and the matching gear 33 are each provided with two. The two matching gears 33 are connected below the two extension seats 11 one by one. The two second gears 53 are located at the two ends of the transmission shaft 51 and are engaged with the two matching gears 33 one by one. The power of the same rotary driving member 31 is output to the two ends of the transmission shaft 51, forming the same driving of the two sides of the headrest frame 2, ensuring the balance of the position force of the two sides of the headrest frame 2 during the front and rear swinging process, and improving the smoothness of the adjustment.

[0041] In some embodiments, the transmission wheel set 5 can adopt the structure as shown in Figure 2 . Figure 2 Figure 2 The transmission wheel set 5 further comprises a third gear 54 rotationally connected to the side of the headrest frame 2. The third gear 54 is located between the second gear 53 and the matching gear 33, and is engaged with the second gear 53 and the matching gear 33 respectively.

[0042] In this embodiment, in order to improve the efficiency of power utilization, a third gear 54 is also provided on both sides of the headrest frame 2. The third gear 54 is located below the mating gear 33. Through the meshing of the two, the driving force acts tangentially along the rotating shaft 4, avoiding the inability to adjust due to the action of the component force, so that the driving force is effectively utilized and the generation of useless work is reduced.

[0043] In some possible implementations, the headrest adjustment structure also includes a controller 6, which is electrically connected to the rotary drive 31 and is used to send control commands to the rotary drive 31. The controller 6 can be electrically connected to the rotary drive 31, and control commands can be sent to the rotary drive 31 to control its start and stop actions. By setting the controller 6, automatic operation can be achieved, avoiding the tedious manual control of the rotary drive 31.

[0044] Specifically, a one-click re-memory function can be set up, and the scenarios to be memorized can be preset in the controller 6, such as driving position, rest position and standby position. By selecting different scenarios, the controller 6 sends instructions to the rotary drive 31 to meet the automatic adjustment requirements.

[0045] Based on the same inventive concept, this application also provides a vehicle, which includes a headrest frame adjustment structure. The headrest frame 2 of the vehicle is rotatably connected to the rear side of the seat frame 1 via a rotating shaft 4. The drive gear 32 is driven by a rotary drive component 31, which, under the action of a cooperating gear 33, causes the headrest frame 2 to swing back and forth, thereby allowing the headrest to effectively conform to the passenger's neck. This structure facilitates the adjustment of the headrest frame 2's tilt position according to the driver's needs, improving operational convenience and enhancing the vehicle's intelligence.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
