[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0023] The following is for reference. Figures 1-3 The headrest 10 according to an embodiment of this application is described. The headrest 10 includes a headrest guide rod 11, a headrest body 12, a mounting base 13, a speaker 14, and a drive assembly 15.

[0024] The headrest body 12 covers a portion of the outer periphery of the headrest guide rod 11. A mounting base 13 is housed within the headrest body 12 and connected to the headrest guide rod 11. A speaker 14 is housed within the headrest body 12 and movably mounted on the side wall 131 of the mounting base 13. A drive assembly 15 is mounted within the mounting base 13 and is drively connected to the speaker 14; the drive assembly 15 is adapted to drive the speaker 14 to move along the side wall 131 of the mounting base 13.

[0025] Currently, most existing seat headrests and speaker systems are fixed designs and lack adjustment functions. Due to differences in height among drivers and passengers, the functional experience of using the headrest speakers varies greatly. For users whose height does not match the seat, it is difficult to find a comfortable listening posture, and the sound effect is also greatly reduced, affecting the comfort of riding and user satisfaction.

[0026] In this regard, this application provides a seat headrest 10, which can adjust the position of the speaker 14 to meet the functional experience of drivers and passengers of different heights.

[0027] Specifically, the headrest 10 may include a headrest guide rod 11, a headrest body 12, a mounting base 13, a speaker 14, and a drive assembly 15. The headrest guide rod 11 can be connected to the seat body of the vehicle to fix the headrest 10 to the seat body. The headrest body 12 can cover part of the outer periphery of the headrest guide rod 11. Optionally, the headrest body 12 can be filled with a foam structure. The mounting base 13 can be housed inside the headrest body 12 and can be connected to the headrest guide rod 11. Optionally, the mounting base 13 and the headrest guide rod 11 can be detachably connected by snap-fit ​​or plug-in, or the mounting base 13 and the headrest guide rod 11 can be detachably connected by screws or bolts, or the mounting base 13 and the headrest guide rod 11 can be directly welded together at the contact surface.

[0028] Furthermore, the speaker 14 can be housed inside the headrest body 12, and the speaker 14 can emit sound to the outside through the headrest body 12. The speaker 14 is movably mounted on the side wall 131 of the mounting base 13. It is understood that the speaker 14 can change its position by moving along the side wall 131 of the mounting base 13. Specifically, the speaker 14 can move in the height direction of the headrest 10, thereby ensuring that the speaker 14 can be positioned to correspond to the head of drivers and passengers of different heights, allowing them to be in a comfortable listening posture and meeting their needs. The drive assembly 15 can be installed inside the mounting base 13. Optionally, the drive assembly 15 and the mounting base 13 can be detachably connected by screws or bolts, or by snap-fit ​​or plug-in connection. The drive assembly 15 can drive the speaker 14 to move along the side wall 131 of the mounting base 13, thereby providing power for the movement of the speaker 14.

[0029] In some embodiments, the user can adjust the position of the speaker 14 by clicking the central control screen, thereby outputting an adjustment signal using the up and down buttons on the steering wheel. This signal is transmitted to the domain controller via a combination switch, and the domain controller controls the drive component 15 to move the speaker 14. Specifically, the user can output a signal from the steering wheel switch, which communicates with the combination switch via LIN communication. The combination switch communicates with the domain controller via CAN communication. The domain controller converts the received signal into an electrical signal to control the forward and reverse rotation of the drive component 15. Optionally, the user can click the central control screen to bring up the speaker 14 position adjustment option for the seat headrest 10. A dialog box will pop up, indicating that the position of the speaker 14 on the seat headrest 10 can be adjusted using the steering wheel buttons. By pressing the up and down buttons on the steering wheel, different LIN signals are transmitted to the combination switch. The combination switch then converts the received LIN signals into CAN signals and transmits them to the domain controller. The domain controller then converts the CAN signals into electrical signals and sends them to the drive component 15. The forward and reverse rotation of the drive component 15 achieves the up and down movement of the speaker 14. It should be noted that, as Figures 1-3 The headrest assembly and speaker shown are existing structures, and a simplified structural diagram is provided here.

[0030] In short, the headrest 10 of this application embodiment has a mounting base 13, a speaker 14, and a drive assembly 15. The mounting base 13 can be housed inside the headrest body 12, the speaker 14 is housed inside the headrest body 12, and the drive assembly 15 is mounted inside the mounting base 13. The drive assembly 15 can drive the speaker 14 to move along the side wall 131 of the mounting base 13, thereby enabling the speaker 14 to move in the height direction. Therefore, the headrest 10 can adjust the position of the speaker 14 to match drivers and passengers of different heights, thereby satisfying the functional experience of drivers and passengers of different heights.

[0031] like Figure 1As shown, in some embodiments of this application, the drive assembly 15 may include a drive member 151, a first transmission member 152 and a second transmission member 153. The drive member 151 may have a drive shaft 1511. Optionally, the drive member 151 may be configured as a drive motor, and the drive shaft 1511 may be the output shaft of the motor. The first transmission member 152 can be driven to the drive shaft 1511, and the second transmission member 153 can be driven to the first transmission member 152. The second transmission member 153 is also connected to the speaker 14. The drive member 151 can be used to drive the second transmission member 153 to move along the side wall 131 of the mounting base 13. It can be understood that the drive member 151 can drive the first transmission member 152 to move, the first transmission member 152 drives the second transmission member 153 to move, and the second transmission member 153 is connected to the speaker 14, thereby driving the speaker 14 to move. Specifically, the first transmission member 152 and the second transmission member 153 can be a gear and a rack. The rack can be fixedly connected to the speaker 14. The gear drives the rack to move through transmission, thereby driving the speaker 14 to move. The above driving method can improve the stability of the speaker 14 when it moves. Alternatively, the second transmission member 153 can be formed with a rack, the rack can cooperate with the gear, and the second transmission member 153 is fixedly connected to the speaker 14.

[0032] like Figure 2 As shown, in some embodiments of this application, the sidewall 131 of the mounting base 13 may have a sliding channel 132. The sliding channel 132 may extend along the extending direction of the sidewall 131. The speaker 14 may have a connecting portion 141, which may pass through the sliding channel 132 and be connected to the second transmission member 153, thereby realizing the connection between the speaker 14 and the second transmission member 153. Optionally, the connecting portion 141 and the second transmission member 153 may be detachably connected by screws or bolts, or the connecting portion 141 and the second transmission member 153 may be detachably connected by snap-fit ​​or plug-in. By providing the connecting portion 141, it can be ensured that the second transmission member 153 is located inside the mounting base 13, while the speaker 14 can slide along the outer surface of the sidewall 131, resulting in better sound transmission of the speaker 14.

[0033] like Figure 2 As shown, in some embodiments of this application, the dimension of the speaker 14 along the width direction of the mounting base 13 is greater than the dimension of the sliding channel 132 along the width direction. It can be understood that the width of the speaker 14 along the width direction of the mounting base 13 is greater than the width of the sliding channel 132, thereby preventing the speaker 14 from falling into the mounting base 13 through the sliding channel 132 when sliding, and ensuring the stability of the speaker 14 when sliding.

[0034] like Figure 3As shown, in some embodiments of this application, the seat headrest 10 further includes a limiting structure 16. The limiting structure 16 can be connected to the second transmission member 153, and a portion of the limiting structure 16 can pass through the sliding channel 132 to clamp on both sides of the side wall 131 of the mounting base 13 along its thickness direction. It can be understood that the limiting structure 16 can clamp on the outer and inner surfaces of the side wall 131, thereby achieving the limiting of the limiting structure 16 and the side wall 131 along the thickness direction. By connecting the limiting structure 16 to the second transmission member 153, it can be ensured that the second transmission member 153 can move along the extension direction of the side wall 131, while also serving to limit the second transmission member 153.

[0035] Furthermore, the sidewall 131 of the mounting base 13 has an inner wall and an outer wall on both sides along its thickness direction. The limiting structure 16 may include a first limiting bracket 161 and a second limiting bracket 162. The first limiting bracket 161 can be housed inside the mounting base 13 and can be connected to the second transmission member 153. The first limiting bracket 161 can be connected to the inner wall via a first pulley 163. The second limiting bracket 162 can be connected to the second transmission member 153, and a portion of the second limiting bracket 162 can pass through the sliding channel 132 to allow the limiting structure 16 to be clamped at the inner and outer walls. The second limiting bracket 162 is connected to the outer wall via a second pulley 164. By providing the first pulley 163 and the second pulley 164, the friction between the first limiting bracket 161 and the second limiting bracket 162 and the sidewall 131 can be reduced to facilitate the sliding of the second transmission member 153. In some embodiments, the number of first pulleys 163 and second pulleys 164 can both be multiple. Multiple first pulleys 163 can slide along the inner wall, and multiple second pulleys 164 can slide along the outer wall. By setting multiple first pulleys 163 and multiple second pulleys 164, the friction between the first limiting bracket 161 and the second limiting bracket 162 and the side wall 131 can be further reduced.

[0036] like Figure 1 As shown, in some embodiments of this application, the drive assembly 15 further includes a first transmission gear 154 and a second transmission gear 155. The first transmission gear 154 can be drivenly connected to the drive shaft 1511, and the second transmission gear 155 can be drivenly connected to the first transmission gear 154. Optionally, the second transmission gear 155 can mesh with the first transmission gear 154. An intermediate shaft 1551 can be provided on the second transmission gear 155. The intermediate shaft 1551 can be drivenly connected to the first transmission member 152. This arrangement can adjust the speed of the drive member 151 to meet actual adjustment requirements.

[0037] like Figure 1As shown, in some embodiments of this application, the drive assembly 15 further includes a third transmission gear 156 and a fourth transmission gear 157. The third transmission gear 156 can be sleeved on the intermediate shaft 1551 and can be drivenly connected to the intermediate shaft 1551. The fourth transmission gear 157 can be drivenly connected to the third transmission gear 156. Optionally, the fourth transmission gear 157 can mesh with the third transmission gear 156. The fourth transmission gear 157 can be provided with a transmission shaft 1571, which can be drivenly connected to the first transmission member 152. By setting the third transmission gear 156 and the fourth transmission gear 157, the overall transmission can be made smoother and vibration can be reduced. In some embodiments, the third transmission gear 156 and the fourth transmission gear 157 can be constructed as bevel gears. This configuration can change the direction of force transmission, which is helpful for the arrangement of the transmission mechanism and reduces the space occupied by the transmission gears.
