[0048] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0049] A vehicle seat 100 and a vehicle body according to the present application will be described below with reference to the accompanying drawings.

[0050] like Figures 1 to 3 As shown, a specific embodiment of the present application provides a vehicle seat 100, including a headrest body 1 and an audio module 3, wherein the audio module 3 is arranged in the headrest body 1 and includes an audio component 31 and a driving component 32, and the driving component 32 is connected to the audio component 31 and is used to drive the audio component 31 to extend out of the headrest body 1.

[0051] Specifically, the vehicle seat 100 includes a headrest body 1 and an audio module 3 built into the headrest body 1. Since the audio module 3 is close to the passenger's head, the audio module 3 can provide the passenger with a better listening experience. The audio module 3 includes an audio component 31 and a headrest body 1. The audio component 31 is arranged inside the headrest body 1. Due to the wrapping of the headrest body 1, the propagation of the sound played by the audio component 31 will be affected. In the present application, the driving component 32 drives the audio component 31 to extend out of the headrest body 1 when the audio component 31 plays the sound, thereby avoiding the interference of the headrest body 1 on the sound propagation, thereby improving the passenger's listening experience.

[0052] Furthermore, when the audio component 31 stops playing, the driving component 32 drives the audio component 31 to be folded into the headrest body 1, thereby facilitating the passengers to sit, thereby improving the practicality of the vehicle seat 100.

[0053] Overall, compared with providing a sound system outside the headrest body 1 to improve the listening experience, providing the sound system module 3 inside the headrest body 1 can reduce the space inside the vehicle occupied by the vehicle seat 100 .

[0054] It should be noted that, in the present application, unless otherwise specified, "left-right direction", "front-back direction" and "up-down direction" all refer to directions based on the passenger sitting on the vehicle seat 100, and the directional words used, such as "up" and "down", refer to the two sides opposite to each other in the up-down direction; "left" and "right" refer to the two sides opposite to each other in the left-right direction, and "front" and "rear" refer to the two sides opposite to each other in the front-back direction; "inside" refers to the inside of a component having an internal space, and "outside" refers to the outside of a component having an internal space, for example, the inside of the headrest body 1 and the outside of the headrest body 1.

[0055] In some embodiments, a receiving groove 4 is opened on the side of the headrest body 1 along the left-right direction, the audio component 31 is disposed in the receiving groove 4 , and the driving component 32 is used to drive the audio component 31 to extend out of the notch of the receiving groove 4 .

[0056] Specifically, there are two receiving slots 4, which are respectively arranged on the left and right sides of the headrest body 1. The slot of the receiving slot 4 on the left side is opened to the left, and the slot of the receiving slot 4 on the right side is opened to the right. There are also two audio modules 3, which are respectively installed in the two receiving slots 4. The audio component 31 on the right side is driven to extend to the right by the driving component 32, and the audio component 31 on the left side is driven to extend to the left by the driving component 32. Surround sound is formed by the audio components 31 arranged on both sides, thereby further improving the listening experience of passengers.

[0057] Furthermore, the audio component 31 is rotatably connected to the groove wall of the accommodating groove 4 , and the extension of the audio component 31 is achieved by rotation, thereby shortening the extension path of the audio component 31 .

[0058] Those skilled in the art can understand that the present application is not limited to the above-mentioned rotational extension method, but can also be a translational extension method, which includes horizontal extension, vertical extension, etc., and other methods and structural forms that can achieve the extension of the audio component 31 should also fall within the scope of protection of the present application.

[0059] like Figure 4 and Figure 5 As shown, preferably, the audio component 31 includes a fan-shaped columnar shell 311 and a speaker 312 arranged in the fan-shaped columnar shell 311, and the fan-shaped columnar shell 311 is connected to the groove wall of the accommodating groove 4 through rotation and cooperates with the driving component 32, so as to realize the rotation and extension of the speaker 312.

[0060] Specifically, the fan-shaped columnar housing 311 includes a central shaft portion 3111, an arc-shaped plate portion 3112, and two radius portions connecting the central shaft portion 3111 and the two ends of the arc-shaped plate portion 3112, wherein the two radius portions are respectively a first radius portion 3113 relatively close to the inside along the circumference of the arc-shaped plate portion 3112 and a second radius portion 3114 relatively close to the outside along the circumference of the arc-shaped plate portion 3112. The central shaft portion 3111 is rotatably connected to the rear groove wall 41 of the receiving groove 4, the first radius portion 3113 is relatively close to the rear groove wall 41 of the receiving groove 4, the second radius portion 3114 is relatively far from the rear groove wall 41 of the receiving groove 4, the arc-shaped plate portion 3112 forms an acoustic mesh surface 5, and the power amplifier end of the speaker 312 is arranged toward the acoustic mesh surface 5.

[0061] It should be noted that, in the present application, the fan-shaped cylindrical shell 311 refers to a cylindrical structure with a fan-shaped cross-section, the central axis portion 3111 refers to the edge formed by translating the center of the fan along the height direction of the cylindrical structure, the arc plate portion 3112 refers to the surface formed by translating the arc of the fan along the height direction of the cylindrical structure, and the radius portion refers to the surface formed by translating the radius of the fan along the height direction of the cylindrical structure.

[0062] Preferably, the second radius portion 3114 is provided with a cover plate 6 for closing the notch of the receiving groove 4. When the sector-shaped columnar housing 311 is received in the receiving groove 4, the notch of the receiving groove 4 is covered by the cover plate 6 on the second radius portion 3114, thereby preventing dust from entering the receiving groove 4 and affecting the performance of the driving assembly 32 and the speaker 312, thereby improving the service life of the vehicle seat 100.

[0063] Specifically, the side of the cover plate 6 facing the second radius portion 3114 is in contact with the second radius portion 3114 and the cover plate 6 is larger than the slot of the receiving slot 4. When the sector-shaped columnar housing 311 is received in the receiving slot 4, the plane where the second radius portion 3114 is located is flush with the plane where the outer edge of the slot of the receiving slot 4 is located, and at the same time, the side of the cover plate 6 facing the second radius portion 3114 is in contact with the outer edge of the slot, thereby reducing the connection structure between the cover plate 6 and the second radius portion 3114 and better sealing the receiving slot 4.

[0064] In some embodiments, the maximum rotation angle of the audio component 31 is greater than 0° and less than or equal to 90°, and the maximum rotation angle of the audio component 31 refers to the angle value that the audio component 31 needs to rotate to extend out of the receiving slot 4.

[0065] Preferably, the maximum rotation angle of the audio component 31 is preferably 35°, the central angle of the fan-shaped cylindrical shell 311 is 70°, the shape of the accommodating groove 4 is a square groove, the central axis portion 3111 is rotatably connected to the outer edge of the rear groove wall 41 of the accommodating groove 4, and when the fan-shaped cylindrical shell 311 rotates 35°, the arc plate portion 3112 is tangent to the front groove wall 42 of the accommodating groove 4, thereby reducing the space occupied by the part of the fan-shaped cylindrical shell 311 extending out of the accommodating groove 4 without affecting the sound propagation of the speaker 312.

[0066] Preferably, a stop structure 7 is provided in the receiving groove 4 , and the stop structure 7 is used to cooperate with the driving assembly 32 to limit the maximum rotation angle of the audio assembly 31 .

[0067] The structure for realizing the rotational connection between the central axis portion 3111 and the outer edge of the rear groove wall 41 of the accommodating groove 4 can be a hinge, a rotating shaft, etc. The above structure is well known to those skilled in the art and does not belong to the core improvement part of the present application, so it will not be repeated here.

[0068] In some embodiments, the driving assembly 32 includes a driving member 321 and a connecting rod mechanism 322 , one end of the connecting rod mechanism 322 is drivingly connected to the driving member 321 , and the other end is connected to the audio assembly 31 and is used to drive the audio assembly 31 to rotate and extend.

[0069] Specifically, the connecting rod mechanism 322 includes a first connecting rod 3221 and a second connecting rod 3222, and the driving member 321 is preferably a motor. One end of the first connecting rod 3221 and one end of the second connecting rod 3222 are rotatably connected by a pin, the other end of the first connecting rod 3221 is connected to the output shaft of the motor, and the other end of the second connecting rod 3222 is rotatably connected to the fan-shaped columnar housing 311 by a pin, and the fan-shaped columnar housing 311, the first connecting rod 3221, the second connecting rod 3222 and the output shaft of the motor all rotate in the same plane.

[0070] Those skilled in the art will appreciate that the present application is not limited to the above-mentioned connecting rod mechanism 322, but may also be other structural forms such as a gear rack structure, a driving member 321 directly driving the central shaft portion 3111 to rotate, and the above-mentioned other structural forms also fall within the protection scope of the present application.

[0071] Furthermore, the rear groove wall 41 of the receiving groove 4 protrudes backward to form a mounting groove 8, the driving member 321 is mounted in the mounting groove 8, the first connecting rod 3221 extends out of the receiving groove 4 and is connected to the driving member 321, the inner side surface of the first radius portion 3113 is provided with a connecting seat 9, and the second connecting rod 3222 passes through the second radius portion 3114 and is rotatably connected to the connecting seat 9. By arranging the driving member 321 in the mounting groove 8 to avoid the driving member 321 occupying the space in the receiving groove 4, the smooth folding of the fan-shaped columnar housing 311 is ensured, and by extending the second connecting rod 3222 into the fan-shaped columnar housing 311 and connecting with the connecting seat 9, the space occupied by the connecting rod mechanism 322 in the receiving groove 4 is reduced, thereby further ensuring the smooth storage of the fan-shaped columnar housing 311.

[0072] Preferably, the stop structure 7 is disposed on the rear groove wall 41 of the accommodating groove 4 and extends forward. When the stop structure 7 abuts against the connecting rod mechanism 322, the connecting rod mechanism 322 reaches the maximum extension length, and at this time, the audio component 31 reaches the maximum rotation angle.

[0073] Specifically, the stop structure 7 is located outside the first connecting rod 3221 and between the fan-shaped columnar housing 311 and the rear slot wall 41 of the receiving slot 4. When the audio component 31 is received in the receiving slot 4, the stop structure 7 does not contact the audio component 31; after the audio component 31 extends out of the receiving slot 4, the stop structure 7 abuts against the first connecting rod 3221.

[0074] Furthermore, by adjusting the length of the stop structure 7 along the front-rear direction and adjusting the inclination angle of the abutting surface between the stop structure 7 and the connecting mechanism, the maximum rotation angle of the audio component 31 can be changed.

[0075] In some embodiments, an ambient light 10 is disposed on the audio assembly 31 , and the ambient light 10 is activated when the audio assembly 31 is extended out of the headrest body 1 , and is turned off when the audio assembly 31 is retracted into the headrest body 1 .

[0076] Specifically, the atmosphere light 10 is disposed on the cover plate 6 , and the atmosphere light 10 is disposed to coordinate with other lights in the vehicle to improve the driving experience of the passengers.

[0077] In some embodiments, the vehicle seat 100 also includes a headrest audio control unit, which is electrically connected to the audio component 31 and the drive component 32 respectively and is configured to: turn off the audio component 31 when the audio component 31 retracts into the headrest body 1; and start the audio component 31 when the audio component 31 extends out of the headrest body 1.

[0078] Preferably, a sensor electrically connected to the headrest audio control unit is provided on the driving component 32. When the sensor detects that the driving component 32 pushes the audio component 31 to extend, the sensor sends a start signal of the audio component 31 to the headrest audio control unit. When the sensor detects that the driving component 32 pulls the audio component 31 to retract, the sensor sends a shut-down signal of the audio component 31 to the headrest audio control unit.

[0079] Preferably, a sensor electrically connected to the headrest audio control unit is provided on the stop structure 7. When the sensor detects that the connecting rod assembly is in contact with the stop structure 7, the sensor sends a start signal of the audio assembly 31 to the headrest audio control unit; when the sensor detects that the connecting rod assembly is separated from the stop structure 7, the sensor sends a shut-down signal of the audio assembly 31 to the headrest audio control unit.

[0080] It should be noted that the principles and structures of the sensor and the headrest audio control unit are well known to those skilled in the art, and do not belong to the core improvement part of the present application, so they will not be described here in detail.

[0081] like Figure 6 and Figure 7 As shown, in some embodiments, the audio module 3 further includes a mounting shell 2 disposed in the headrest body 1, and the audio component 31 and the driving component 32 are both mounted in the mounting shell 2. Since the headrest body 1 is made of a soft material, the audio component 31 and the driving component 32 are mounted by providing the mounting shell 2, thereby facilitating the installation and replacement of the audio component 31 and the driving component 32.

[0082] In some embodiments, the vehicle seat 100 includes a seat body, and a height adjustment mechanism is provided between the headrest body 1 and the seat body, and the height adjustment mechanism is used to adjust the height of the headrest body 1 relative to the seat body.

The distance between the headrest body 1 and the seat body is adjusted by adjusting the depth of the headrest rods 200 inserted into the seat body, thereby adjusting the height of the vehicle seat 100 relative to the seat body, thereby adapting to people of different heights to improve practicality.

[0084] The present application also provides a vehicle, including a vehicle seat 100 and a vehicle audio device. Since the vehicle adopts all embodiments of the vehicle seat 100, the vehicle has all the beneficial effects brought by the vehicle seat 100.

[0085] In some implementations, the audio module 3 is started and / or shut down synchronously with the vehicle audio device.

[0086] Specifically, the vehicle also includes an on-board audio control unit electrically connected to the on-board audio device, and the on-board audio control unit is electrically connected to the headrest audio control unit, and the on-board audio device is turned on and off by the on-board audio control unit: when the on-board audio control unit turns on the on-board audio device, the on-board audio control unit simultaneously sends an electrical signal to the headrest audio control unit, and the headrest audio control unit controls the audio module 3 to turn on after receiving the electrical signal; when the on-board audio control unit turns off the on-board audio device, the on-board audio control unit simultaneously sends an electrical signal to the headrest audio control unit, and the headrest audio control unit controls the audio module 3 to turn off after receiving the electrical signal.

[0087] It should be noted that the control principle and structure of the vehicle audio control unit and the headrest audio control unit are well known to those skilled in the art, and do not belong to the core improvement part of this application, so they will not be repeated here.
