[0061] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0062] According to the first aspect of the present application, referring to Figures 1 to 8 The present application provides a seat. The seat includes a seat body 1, a position adjustment mechanism 2, an angle adjustment mechanism 3 and a headrest 4. The position adjustment mechanism 2 is connected to the seat body 1. The angle adjustment mechanism 3 is connected to the position adjustment mechanism 2. The headrest 4 is connected to the angle adjustment mechanism 3. The angle adjustment mechanism 3 is configured to adjust the inclination angle of the headrest 4. The position adjustment mechanism 2 is configured to adjust the position of the angle adjustment mechanism 3 in the width direction of the seat body 1.

[0063] In an embodiment of the present application, a position adjustment mechanism 2 and an angle adjustment mechanism 3 are provided between the seat body 1 and the headrest 4. The angle adjustment mechanism 3 can adjust the inclination angle of the headrest 4, and the position adjustment mechanism 2 can adjust the installation position of the headrest 4 in the width direction of the seat body 1. Thus, it can accommodate drivers or passengers of different heights and body shapes, and can also adjust the position of the headrest 4 in the width direction of the seat or adapt to different models of headrests 4.

[0064] It is understandable that when the angle adjustment mechanism 3 adjusts the tilt angle of the headrest 4, the rotation connection between the headrest 4 and the angle adjustment mechanism 3 is used as the rotation center, so that the upper end of the headrest 4 rotates toward the direction close to the driver's or passenger's head or the headrest 4 rotates away from the driver's or passenger's head. Based on the angle adjustment of the headrest 4, the tilt angle of the headrest 4 can be adjusted according to the driver's or passenger's own body shape, driving habits and hobbies to obtain the best support and fit. Such personalized adjustment can ensure that the driver's head and neck are comfortably supported and reduce the fatigue caused by long-term driving. And by adjusting the angle of the headrest 4, the driver or passenger can maintain an appropriate distance and angle between the head and the headrest 4, effectively reducing the pressure on the cervical spine and avoiding cervical fatigue or discomfort.

[0065] Since the angle adjustment mechanism 3 is installed on the position adjustment mechanism 2, when the position adjustment mechanism 2 adjusts the position of the angle adjustment mechanism 3 in the width direction of the seat body 1, the installation position of the headrest 4 can be adjusted. When the headrest 4 is installed on the position adjustment mechanism 2 through only one angle adjustment mechanism 3, the position adjustment mechanism 2 can drive the headrest 4 to move in the width direction of the seat body 1 to meet different usage requirements. When the headrest 4 is installed on the position adjustment mechanism 2 through two angle adjustment mechanisms 3, the two angle adjustment mechanisms 3 can be driven to move closer to or farther from each other, thereby meeting different models of headrests 4.

[0066] In some embodiments, the headrest 4 is provided with speakers 42 on opposite sides in the width direction thereof. The speakers 42 may adopt a high-quality surround sound system, which not only provides immersive auditory enjoyment, but also supports noise cancellation, creating a quieter driving environment for the driver.

[0067] In some embodiments, Figure 3 and Figure 4 As shown, the angle adjustment mechanism 3 includes a fixed seat 31, a rotating seat 32 and a first locking assembly 33. The fixed seat 31 is connected to the position adjustment mechanism 2. The rotating seat 32 is rotatably mounted on the fixed seat 31. The headrest 4 is connected to the rotating seat 32. The first locking assembly 33 is connected to the fixed seat 31 and is used to lock the position of the rotating seat 32.

[0068] It is understandable that the headrest 4 can be driven to adjust the angle by rotating the rotating seat 32 on the fixed seat 31, and the first locking assembly 33 is used to lock the position of the rotating seat 32 to achieve the fixed position of the headrest 4. When the tilt angle of the headrest 4 needs to be adjusted, the first locking assembly 33 is in an unlocked state so that the rotating seat 32 and the fixed seat 31 can rotate relative to each other. After the tilt angle of the headrest 4 is adjusted, the first locking assembly 33 is in a locked state so that the rotating seat 32 and the fixed seat 31 cannot rotate relative to each other.

[0069] It should be noted that the rotating shaft 312 of the rotating seat 32 and the fixing seat 31 is arranged along the width direction of the seat body 1 .

[0070] In some embodiments, Figure 4 As shown, the fixing seat 31 is provided with a first mounting groove 311 with a notch away from the position adjustment mechanism 2. A rotating shaft 312 is rotatably connected in the first mounting groove 311. The rotating seat 32 is connected to the rotating shaft 312. The first end of the rotating shaft 312 passes through the first mounting groove 311 and is connected to the first locking assembly 33.

[0071] It is understandable that the first mounting groove 311 is used to rotatably connect the rotating seat 32, and the rotating seat 32 and the fixed seat 31 are rotatably mounted through the rotating shaft 312. The first end of the rotating shaft 312 passes through the first mounting groove 311 and is connected to the first locking assembly 33, so that the first locking assembly 33 can lock the position of the rotating shaft 312. When the position of the rotating shaft 312 is locked by the first locking assembly 33, the rotating seat 32 and the fixed seat 31 cannot rotate relative to each other. In this way, the position locking of the headrest 4 after the tilt angle is adjusted is achieved.

[0072] It should be noted that the rotating seat 32 is configured with a connecting portion 321 extending toward the first mounting groove 311, the connecting portion 321 extends into the first mounting groove 311, and is connected to the rotating shaft 312. Therefore, the rotating seat 32 does not need to be accommodated in the first mounting groove 311, and the size of the fixed seat 31 and the first mounting groove 311 can be reduced, which is conducive to the miniaturization design of the position adjustment mechanism 2.

[0073] In some embodiments, the connecting portion 321 is relatively fixed to the rotating shaft 312 so that the connecting portion 321 cannot rotate in the first mounting groove 311 after the rotating shaft 312 is locked, thereby ensuring that the position of the headrest 4 can be locked.

[0074] In some embodiments, Figure 6 As shown, the first locking assembly 33 includes a first driving member 331, a transmission member 332 and a first locking member 333. The first driving member 331 is connected to the fixing seat 31. The transmission member 332 is connected to the first driving member 331. The first locking member 333 is connected to the transmission member 332. The first end of the rotating shaft 312 passes through the first mounting groove 311 and is connected to the second locking member 334. The transmission member 332 is configured to drive the first locking member 333 to connect with the second locking member 334 to lock the position of the rotating shaft 312. Alternatively, the first locking member 333 is driven to disconnect from the second locking member 334 to unlock the rotating shaft 312.

[0075] It is understandable that the first driving member 331 can drive the first locking member 333 to move through the transmission member 332. When the first locking member 333 is connected to the second locking member 334, the first locking member 333 and the second locking member 334 cooperate to lock the position of the rotating shaft 312. When the first locking member 333 and the second locking member 334 are separated from each other, the connection between the first locking member 333 and the second locking member 334 is disconnected, the first locking member 333 is in a free state, and the rotating shaft 312 can rotate so that the headrest 4 can be adjusted in angle.

[0076] In some embodiments, the first driving member 331 is an electric motor, etc. The transmission member 332 is a structure capable of transmitting power, including but not limited to a gear transmission mechanism, a chain transmission mechanism, a belt transmission mechanism, a worm wheel 3243 worm 3242 transmission mechanism, etc.

[0077] It should be noted that the first mounting groove 311 faces upward and is a through groove in the thickness direction of the seat body 1 (ie, the length direction of the vehicle) to prevent the groove wall of the first mounting groove 311 from interfering with the rotation of the connecting portion 321 in the first mounting groove 311 .

[0078] In some embodiments, Figure 5 As shown, one of the first locking member 333 and the second locking member 334 is a tooth sleeve, and the other is a locking tooth. The tooth sleeve is sleeved on the locking tooth to lock the position of the rotating shaft 312.

[0079] It can be understood that the locking tooth is a structure with a plurality of protruding teeth on the periphery, and the tooth sleeve is a structure with a plurality of tooth grooves on the inner ring. When the tooth sleeve is sleeved on the locking tooth, if the position of one of them is fixed, the other will not be able to rotate. Therefore, when the tooth sleeve is sleeved on the locking tooth, the position of the rotating shaft 312 can be locked.

[0080] In some embodiments, the first locking member 333 is a toothed sleeve, and the second locking member 334 is a locking tooth. That is, the first end of the rotating shaft 312 passes through the first mounting slot 311 and is connected to a toothed sleeve, and the transmission member 332 is connected to a locking tooth. At this time, the end of the toothed sleeve connected to the rotating shaft 312 is a solid structure, and the end of the toothed sleeve away from the rotating shaft 312 forms a slot. When the locking tooth is engaged with the slot, the position of the rotating shaft 312 is locked.

[0081] In some embodiments, the first locking member 333 is a locking tooth, and the second locking member 334 is a gear sleeve. That is, the first end of the rotating shaft 312 passes through the first installation slot 311 and is connected to a locking tooth, and the transmission member 332 is connected to a gear sleeve. At this time, the rotating shaft 312 is coaxially connected with the locking tooth.

[0082] In the embodiment of the present application, the position of the rotating shaft 312 is locked by locking teeth and tooth sleeves. Based on the locking teeth, a plurality of convex teeth can be arranged along the circumference thereof, and the tooth sleeves are also provided with a plurality of tooth grooves adapted thereto, which can increase the range of angle adjustment and make the adjustment and locking process smoother.

[0083] In some embodiments, Figure 6 As shown, the transmission member 332 includes a first gear 3321, a second gear 3322 and a first screw rod 3323. The first gear 3321 is connected to the output shaft of the first driving member 331. The second gear 3322 is meshed with the first gear 3321. The first screw rod 3323 is coaxially connected with the second gear 3322. Among them, the first locking member 333 is configured with a first connecting hole 3331. The first connecting hole 3331 is threadedly connected with the first screw rod 3323.

[0084] It can be understood that the first driving member 331 can drive the first gear 3321 to rotate. The rotation of the first gear 3321 can drive the second gear 3322 to rotate. The rotation of the second gear 3322 can cause the first screw rod 3323 to rotate. Since the first locking member 333 is threadedly connected to the first screw rod 3323 through the first connecting hole 3331, the first screw rod 3323 can drive the first locking member 333 to move. When the first screw rod 3323 drives the first locking member 333 away from the second locking member 334, the first locking mechanism can be switched from the locked state to the unlocked state. After the first screw rod 3323 drives the first locking member 333 to connect with the second locking member 334, the first locking mechanism can be switched from the unlocked state to the locked state.

[0085] In some embodiments, the first gear 3321 and the second gear 3322 are both bevel teeth, and the first gear 3321 and the second gear 3322 are vertically meshed. Thus, the direction of the force can be changed through the transmission of the first gear 3321 and the second gear 3322, so that the force transmitted in the height direction can be converted into a force in the horizontal direction, thereby driving the first screw rod 3323 set in the horizontal direction to rotate based on the rotation of the second gear 3322.

[0086] The embodiment of the present application realizes the action of the first locking member 333 through the gear transmission of the first gear 3321 and the second gear 3322. After the position of the first locking member 333 is adjusted, the transmission self-locking can be realized based on the engagement of the bevel gears, thereby realizing the position fixation of the first locking member 333 to prevent the first locking member 333 and / or the second locking member 334 from being actuated under the action of external force, thereby preventing the first locking mechanism from being unable to lock the rotating shaft 312, thereby preventing the position fixation of the headrest 4 from being unreliable.

[0087] In some embodiments, Figure 5As shown, the first locking member 333 is also configured with a second connecting hole 3332. The fixing seat 31 is provided with a limiting rod 313. The limiting rod 313 is slidably connected to the second connecting hole 3332.

[0088] It can be understood that based on the first screw rod 3323 driving the first locking piece 333 to move, it is necessary to utilize the sliding cooperation between the limit rod 313 and the second connecting hole 3332 to achieve the anti-rotation limit of the first locking piece 333, ensuring that the first locking piece 333 can only slide in the width direction of the seat body 1 under the drive of the first screw rod 3323.

[0089] In some embodiments, a first limiting portion 314 is disposed at one end of the limiting rod 313 away from the fixing seat 31 .

[0090] It is understandable that if Figure 4 and Figure 5 As shown, the first limiting portion 314 can limit the sliding range of the first locking member 333 so that the first locking member 333 can only move within the range from the fixing seat 31 to the first limiting portion 314, thereby preventing the first locking member 333 from falling off from the limiting rod 313.

[0091] In some embodiments, the first limiting portion 314 is integrally formed with the limiting rod 313. The first limiting portion 314 and the limiting rod 313 can both be set to be cylindrical. The diameter of the first limiting portion 314 is greater than the diameter of the limiting rod 313. The aperture of the second connecting hole 3332 is the same as the diameter of the limiting rod 313.

[0092] In some embodiments, Figure 4 and Figure 5 As shown, the second end of the rotating shaft 312 passes through the first installation slot 311 and is connected to the second limiting portion 315 .

[0093] It can be understood that the second limiting portion 315 can prevent the second end of the rotating shaft 312 from falling off from the fixing seat 31 , so as to achieve reliable fixation of the rotating shaft 312 .

[0094] In some embodiments, the second limiting portion 315 may be integrally formed with the rotating shaft 312 , or the second limiting portion 315 may be welded or connected to the rotating shaft 312 in other ways.

[0095] In some embodiments, the second position-limiting portion 315 may also be connected to a driving mechanism. The driving mechanism may drive the second position-limiting portion 315 to rotate, so that the second position-limiting portion 315 drives the rotating shaft 312 to rotate, thereby realizing the motorized adjustment of the tilt angle of the headrest 4. Alternatively, the second position-limiting portion 315 only has the effect of limiting and preventing falling off, in which case the tilt angle of the headrest 4 may be adjusted manually.

[0096] It should be noted that, regardless of manual adjustment or electric adjustment, the structural setting of the angle adjustment mechanism 3 in the embodiment of the present application can make the tilt angle adjustment range of the headrest 4 larger, and better adaptable to the height and body shape of the user. At the same time, the adjustment process is smoother, and the locking and unlocking processes are also smoother and more reliable, which improves the user experience.

[0097] In some embodiments, Figure 7 As shown, the rotating seat 32 is configured with a second mounting groove 322 with a notch facing away from the fixed seat 31. A mounting notch 323 connected to the second mounting groove 322 is formed on the side surface of the rotating seat 32. A second locking assembly 324 is arranged in the mounting notch 323. The headrest 4 is connected to the second mounting groove 322. The second locking assembly 324 is used to lock the position of the headrest 4.

[0098] It is understandable that the second mounting groove 322 is used to connect the headrest 4 to achieve mutual connection between the headrest 4 and the rotating seat 32. Since the headrest 4 is fixed to the rotating seat 32, when the rotating seat 32 rotates along the fixed seat 31, the tilt angle of the headrest 4 can be adjusted. The side surface of the rotating seat 32 is configured with a mounting notch 323 connected to the second mounting groove 322, so that the second locking assembly 324 is set in the mounting notch 323, thereby, the position of the headrest 4 can be locked by the second locking, and the headrest 4 and the rotating seat 32 can be reliably fixed.

[0099] The headrest 4 can be inserted into the second mounting groove 322 from the upper side of the rotating seat 32. When the fixing column 41 of the headrest 4 is locked by the second locking assembly 324, the headrest 4 and the rotating seat 32 can be fixed to each other, ensuring that the headrest 4 will not fall off the rotating seat 32 and the position will not shift during use.

[0100] In some embodiments, the fixing column 41 is a circular column, and the second mounting groove 322 is a circular groove.

[0101] In some embodiments, Figure 8 As shown, the second locking assembly 324 includes a second driving member 3241, a worm 3242, a worm wheel 3243 and a cam 3244. The second driving member 3241 is connected to the rotating seat 32. The worm 3242 is connected to the output shaft of the second driving member 3241. The worm wheel 3243 is transmission-connected to the worm 3242. The cam 3244 is rotatably mounted in the mounting notch 323. The cam 3244 is connected to the worm wheel 3243 and rotates under the action of the worm wheel 3243. Among them, the headrest 4 has a fixing column 41. The fixing column 41 is inserted into the second mounting groove 322. The cam 3244 has a protrusion 3245. The protrusion 3245 is used to abut the fixing column 41 to lock the position of the headrest 4.

[0102] It is understandable that the second driving member 3241 can drive the worm 3242 to rotate, and the worm 3242 drives the worm wheel 3243 to rotate. When the worm wheel 3243 rotates, the cam 3244 can be driven to rotate in the installation notch 323. When the protrusion 3245 of the cam 3244 abuts against the fixing column 41, the position of the headrest 4 can be locked.

[0103] It should be noted that mounting shafts are provided on opposite sides of the cam 3244, and the two mounting shafts are rotatably connected to the groove walls on opposite sides of the second mounting groove 322. The rotating seat 32 is also formed with a mounting hole connected to the second mounting groove 322, and the mounting hole is connected to the mounting notch 323 through a channel. One of the mounting shafts is inserted into the channel and penetrates into the mounting hole. The worm gear 3243 can be rotatably installed in the mounting hole. Thus, the worm gear 3243 and the cam 3244 are coaxially connected.

[0104] The embodiment of the present application is based on the transmission method of the worm wheel 3243 and the worm 3242, so that after the second driving member 3241 loses power, the position of the protrusion 3245 can be locked based on the self-locking of the worm wheel 3243 and the worm 3242, ensuring that the headrest 4 will not fall off the rotating seat 32 and the position will not shift during use.

[0105] In some embodiments, Figure 8 As shown, the outer surface of the rotating seat 32 is provided with a first fixing portion 325 and a second fixing portion 326 spaced apart along the height direction thereof. The opposite ends of the worm 3242 are rotatably connected to the first fixing portion 325 and the second fixing portion 326 respectively.

[0106] It is understandable that the first fixing portion 325 and the second fixing portion 326 are used to rotate and fix the worm 3242 so that it can be located outside the rotating seat 32. The first fixing portion 325 and the second fixing portion 326 can be welded to the outer surface of the rotating seat 32; or the first fixing portion 325 and the second fixing portion 326 are integrally formed on the outer surface of the rotating seat 32.

[0107] In some embodiments, bearings are installed on both the first fixing portion 325 and the second fixing portion 326 , and the worm 3242 is connected to the inner ring of the bearing.

[0108] In some embodiments, the second driving member 3241 is fixed to a side of the first fixing portion 325 or the second fixing portion 326 away from the worm 3242. The output shaft of the second driving member 3241 passes through the first fixing portion 325 or the second fixing portion 326 and is coaxially connected to the worm 3242. The second driving member 3241 includes a motor, etc.

[0109] In some embodiments, Figure 2As shown, the position adjustment mechanism 2 includes an adjustment seat 21. The adjustment seat 21 is installed on the seat body 1. A slide groove 211 is configured on a side of the adjustment seat 21 away from the seat body 1. The fixed seat 31 is slidably connected to the slide groove 211.

[0110] It is understandable that the position of the fixing seat 31 is adjusted based on the sliding installation of the fixing seat 31 and the slide groove 211. The slide groove 211 extends along the width direction of the seat body 1, so that the position adjustment direction of the fixing seat 31 is the width direction of the seat, and the fixed position of the headrest 4 in the width direction of the seat body 1 can be changed or different models of headrests 4 can be adapted.

[0111] In some embodiments, Figure 2 and Figure 3 As shown, the position adjustment mechanism 2 also includes a second screw rod 22 and a third driving member 23. The second screw rod 22 is rotatably installed in the slide slot 211. The third driving member 23 is connected to the adjustment seat 21. The third driving member 23 is transmission-connected with the second screw rod 22. The fixing seat 31 is configured with a third connecting hole 316. The third connecting hole 316 is threadedly connected with the second screw rod 22.

[0112] It can be understood that the third driving member 23 drives the second screw rod 22 to rotate, so that the second screw rod 22 drives the fixing seat 31 to slide along the second screw rod 22, so as to adjust the position of the fixing seat 31, thereby adjusting the installation position of the angle adjustment mechanism 3. In this way, the fixing position of the headrest 4 in the width direction of the seat body 1 can be changed or different models of headrests 4 can be adapted.

[0113] It should be noted that the second screw rod 22 extends along the length direction of the slide slot 211 , so that when the second screw rod 22 rotates, the fixing seat 31 is driven to slide along the length direction of the slide slot 211 .

[0114] In some embodiments, the fixing seat 31 is set to be cylindrical. The diameter of the fixing seat 31 can be equal to the width of the slide groove 211. Therefore, based on the cooperation between the slide groove 211 and the fixing seat 31, the fixing seat 31 is prevented from rotating and limited, so as to ensure that the fixing seat 31 can only slide along the extension direction of the slide groove 211 under the action of the second screw rod 22.

[0115] In some embodiments, the fixing seat 31 is set to be square. The side length of the fixing seat 31 can be equal to the width of the slide groove 211. Therefore, based on the cooperation between the slide groove 211 and the fixing seat 31, the fixing seat 31 is prevented from rotating and limited, so as to ensure that the fixing seat 31 can only slide along the extension direction of the slide groove 211 under the action of the second screw rod 22.

[0116] In some embodiments, Figure 2 and Figure 3As shown, the second screw rod 22 has a first thread segment 221 and a second thread segment 222, and two angle adjustment mechanisms 3 are provided. The fixing seats 31 of the two angle adjustment mechanisms 3 are respectively threadedly connected to the first thread segment 221 and the second thread segment 222. The second screw rod 22 is configured to drive the two angle adjustment mechanisms 3 to move closer to each other or away from each other.

[0117] It can be understood that, based on forming two threaded sections on the second screw rod 22 to connect the two angle adjustment mechanisms 3 , the second screw rod 22 is used to drive the two angle adjustment mechanisms 3 to move closer to or away from each other, thereby adapting to different models of headrests 4 .

[0118] The headrest 4 usually has two fixing columns 41. One of the fixing columns 41 is connected to one angle adjustment mechanism 3, and the other fixing column 41 is connected to another angle adjustment mechanism 3, so as to fix the headrest 4 on the seat body 1. Since the spacing between the two fixing columns 41 in different types of headrests 4 is different, the relative positions of the two angle adjustment mechanisms 3 are adjusted based on the second screw rod 22 so that they can adapt to different types of headrests 4, improve the applicability of the seat, and facilitate the installation of the headrest 4.

[0119] In some embodiments, the first thread segment 221 and the second thread segment 222 are symmetrically distributed on the second screw rod 22, and the first thread segment 221 and the second thread segment 222 have opposite thread rotation directions. Thus, the second screw rod 22 can drive the two angle adjustment mechanisms 3 to move toward or away from each other smoothly and symmetrically when rotating.

[0120] When the two angle adjustment mechanisms 3 are close to each other, a small-sized headrest 4 can be adapted. When the two angle adjustment mechanisms 3 are close to each other, a large-sized headrest 4 can be adapted.

[0121] In some embodiments, the third driving member 23 includes an electric motor, etc.

[0122] It should be noted that, based on the structure of the position adjustment mechanism 2, the angle adjustment mechanism 3 and the headrest 4 of the seat, the headrest 4 can be easily and quickly installed on the seat body 1 without complicated steps or tools. The user only needs to follow the instructions or video tutorials to easily complete the installation and adjustment of the headrest 4, which greatly saves the user's time and energy and improves the user experience.
