Description

Seats, headrests and vehicles Technical Field

[0001] The present application relates to the field of smart vehicles, and more particularly, to a seat, a headrest, and a vehicle. Background Art

[0002] With the development of intelligent vehicles, vehicles have evolved from being just a means of transportation to a mobile vehicle that integrates travel, entertainment, and leisure. The headrests in vehicle seats currently on the market primarily provide simple support. The audio system in the vehicle is too simple, preventing users from experiencing it individually. A music headrest can provide users with a partitioned, independent experience. Because the audio wiring harness in the music headrest is physically connected to the seat wiring harness in the seat back, the music headrest cannot be removed from the seat back. This prevents the seat back from reclining, impacting the user's sleeping experience.

[0003] Summary of the Invention

[0004] The present application provides a seat, a headrest and a vehicle, which can realize that the headrest can be inserted into or pulled out from the seat back, satisfying the user's listening effect and sleeping experience, thereby helping to improve the user experience.

[0005] In a first aspect, the present application provides a seat comprising a seat back, the seat back comprising a connector, the connector comprising a signal transmission structure and a seat wiring harness, the signal transmission structure abutting against an inner wall of a headrest rod, the seat wiring harness being connected to the signal transmission structure.

[0006] Based on the above technical solution, by installing a connector in the seat back, the signal can be transmitted through the seat wiring harness, the signal transmission structure on the connector, and the headrest rod to the speaker in the headrest, allowing the headrest to be removed from the seat back and inserted. This not only satisfies the user's listening experience, but also improves the user's sleeping experience.

[0007] In some possible implementations, the seat back further includes a headrest guide sleeve, and the headrest rod can be inserted into the headrest guide sleeve and can also be pulled out from the headrest guide sleeve.

[0008] In some possible implementations, the position of the connector in the seat back is fixed.

[0009] Exemplarily, the headrest guide sleeve includes an opening through which the headrest rod can be inserted or removed. The connector can be arranged below the opening.

[0010] In some possible implementations, the signal transmission structure may be connected to the inner wall of the headrest rod via magnetic force.

[0011] In combination with the first aspect, in certain implementations of the first aspect, the connector further includes a snap-fit ​​structure, and when the connector is in the first state, the snap-fit ​​structure is snap-fitted to the inner wall of the headrest rod.

[0012] Based on the above technical solution, a snap-fit ​​structure is provided on the connector, which can snap into place with the inner wall of the headrest rod. This allows the connector to move with the rod as the user adjusts the rod upward or downward, preventing it from falling off the rod. This helps ensure that signals are transmitted through the seat wiring harness, signal transmission structure, and headrest rod to the headrest speakers, thereby ensuring a consistent listening experience for the user during movement of the rod.

[0013] In some possible implementations, the connector is in a first state, including: the connector is located in an inner wall of the headrest rod.

[0014] In some possible implementations, the snap-fit ​​structure is located below the signal transmission structure.

[0015] In combination with the first aspect, in certain implementations of the first aspect, the seat back further includes an upper plug-in structure and a lower plug-in structure, the lower plug-in structure includes a transverse locking mechanism and a locking block structure, the lower plug-in structure is arranged on the outside of the headrest rod, and when the connector is in the second state, the connector drives the lower plug-in structure to move and when the lower plug-in structure is inserted into the upper plug-in structure, the transverse locking mechanism is triggered to squeeze the locking block structure, so that the locking block structure is engaged with the clamping structure.

[0016] Based on the above technical solution, the connector can drive the lower plug-in structure to move, and when the lower plug-in structure is inserted into the upper plug-in structure, the transverse locking mechanism is triggered to squeeze the locking block structure, thereby engaging the locking block structure with the clamping structure. The interaction force between the clamping structure and the inner wall of the headrest rod disappears, so that the connector remains in the seat back while the headrest rod is removed. This facilitates the front seat back to be flattened and connected to the rear seat cushion, providing users with more sleeping space and helping to improve their sleeping experience.

[0017] In some possible implementations, the connector is in the second state, including: the connector moves upward along with the headrest rod.

[0018] In some possible implementations, the upper plug-in structure is located outside the lower plug-in structure, and a space is included between the upper plug-in structure and the headrest rod, and the lower plug-in structure can move in the space.

[0019] In some possible implementations, the transverse dimension between the upper plug-in structure and the headrest rod is greater than or equal to the transverse dimension of the lower plug-in structure, so that the lower plug-in structure can move in the space.

[0020] In some possible implementations, when the transverse dimension between the upper plug-in structure and the headrest rod is greater than the transverse dimension of the lower plug-in structure, the difference between the transverse dimension between the upper plug-in structure and the headrest rod and the transverse dimension of the lower plug-in structure is less than or equal to a predetermined difference. Thus, when the dimension between the upper and lower plug-in structures is small, the transverse locking mechanism can be squeezed by the upper plug-in structure when the lower plug-in structure is inserted into the upper plug-in structure, thereby causing the transverse locking mechanism to squeeze the locking block structure.

[0021] In some possible implementations, the upper plug-in structure is fixedly connected to the headrest guide sleeve.

[0022] In combination with the first aspect, in certain implementations of the first aspect, the clamping structure includes a support arm and a spring, the upper end of the support arm rotates around a fixed point on the connector, the lower end of the support arm is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the connector.

[0023] Based on the above technical solution, when the connector is inserted into the headrest rod, the spring in the clamping structure is compressed, and an interaction force is formed between the support arm and the inner wall of the headrest rod, so that the connector can be clamped with the inner wall of the headrest rod.

[0024] In some possible implementations, the connector includes a plurality of snap-fit ​​structures. For example, the connector includes two snap-fit ​​structures, and the two snap-fit ​​structures can be symmetrically arranged.

[0025] In combination with the first aspect, in certain implementations of the first aspect, the seat back includes a lower plug-in structure, the lower plug-in structure includes a locking block structure and the lower plug-in structure is fixedly connected to the connector, the locking block structure is connected to the headrest rod sleeve or by magnetic force, and when the locking block structure is in the third state, the locking block structure drives the lower plug-in structure and the connector to move in a first direction, and the first direction is from the bottom of the seat to the top of the seat.

[0026] Based on the above technical solution, by connecting the locking block structure with the headrest rod sleeve or by magnetic force, the locking block structure can drive the lower plug-in structure and the connector to move upward or downward during the upward or downward movement of the headrest rod, thereby preventing the connector from falling off the headrest rod, helping to ensure that the signal is transmitted to the headrest audio through the seat wiring harness, signal transmission structure, and headrest rod, thereby ensuring the user's listening experience during the movement of the headrest rod.

[0027] In some possible implementations, the locking block structure is in a third state, including: the headrest rod is not pulled out from the seat back.

[0028] In combination with the first aspect, in certain implementations of the first aspect, the locking block structure includes a recessed portion, the seat back further includes an upper plug-in structure, the upper plug-in structure includes a transverse locking mechanism, and the transverse locking mechanism cooperates with the recessed portion. When the locking block structure is inserted into the upper plug-in structure, the transverse locking mechanism squeezes the recessed portion to stop the lower plug-in structure and the connector from moving.

[0029] Based on the above technical solution, when the locking block structure drives the lower plug-in structure to insert into the upper plug-in structure, it triggers the transverse locking mechanism in the upper plug-in structure to squeeze the recessed portion of the locking block structure, thereby stopping the movement of the lower plug-in structure and the plug-in component. This allows the headrest rod to be removed from the seat back while the plug-in component remains in the seat back. This facilitates the front seat back to be flattened and connected to the rear seat cushion, providing users with more sleeping space and helping to improve their sleeping experience.

[0030] In some possible implementations, one side of the upper plug-in structure is in contact with the headrest rod.

[0031] In some possible implementations, the upper plug-in structure can be fixedly connected to the headrest guide sleeve. When the locking block structure is inserted into the upper plug-in structure, the transverse locking mechanism can compress the locking block structure, thereby stopping the locking block structure, the lower plug-in structure, and the connector. This allows the headrest rod to be removed from the headrest guide sleeve.

[0032] In some possible implementations, the upper plug-in structure can move within a certain range. When the locking block structure is inserted into the upper plug-in structure, the transverse locking mechanism can compress the locking block structure. At this time, the upper plug-in structure, the locking block structure, the lower plug-in structure, and the connector can continue to move upward due to the interaction between the locking block structure and the headrest rod. When the upper plug-in structure contacts the headrest guide sleeve, the upper plug-in structure stops moving, thereby causing the locking block structure, the lower plug-in structure, and the connector to stop moving. This allows the headrest rod to be pulled out of the headrest guide sleeve.

[0033] In some possible implementations, a space is formed between the upper plug-in structure and the headrest rod, and the locking block structure can move in the space. The locking block structure cooperates with the upper plug-in structure, so that the locking block structure can be smoothly inserted into the upper plug-in structure.

[0034] In some possible implementations, the recessed portion is an opening provided on the locking block structure, and the size of the transverse locking mechanism matches the size of the opening, so that when the locking block structure is inserted into the upper plug-in structure, the transverse locking mechanism squeezes the locking block structure through the opening.

[0035] In some possible implementations, the lower plug-in structure includes a space, and the plug-in component can be accommodated in the space.

[0036] In combination with the first aspect, in some implementations of the first aspect, the signal transmission structure is a retractable spring.

[0037] In some possible implementations, the connector includes a plurality of retractable springs.

[0038] Exemplarily, the connector includes four retractable springs.

[0039] In combination with the first aspect, in certain implementations of the first aspect, when the connector is not inserted into the headrest rod, the area of ​​the first cross-section of the retractable spring is smaller than the area of ​​the cross-section of the inner cavity of the headrest rod and the area of ​​the second cross-section of the retractable spring is larger than the area of ​​the cross-section of the inner cavity of the headrest rod, and the first cross-section is a cross-section close to the top of the seat back.

[0040] Based on the above technical solution, the cross-sectional area of ​​the top of the retractable reed is smaller than the cross-sectional area of ​​the inner cavity of the headrest rod, which can ensure that the connector can be smoothly inserted into the headrest rod when the headrest rod is inserted into the seat back; the cross-sectional area of ​​the retractable reed other than the top is larger than the cross-sectional area of ​​the inner cavity of the headrest rod, so that after the connector is inserted into the headrest rod, the retractable reed can abut against the inner wall of the headrest rod, so that the signal is transmitted to the speaker in the headrest through the seat wiring harness, the retractable reed and the headrest rod.

[0041] In a second aspect, the present application provides a headrest, which includes a speaker, a speaker wiring harness and a headrest rod, wherein one end of the speaker wiring harness is connected to the speaker and the other end of the speaker wiring harness is connected to the headrest rod, and the headrest rod transmits a signal to the speaker through the speaker wiring harness.

[0042] Based on this technical solution, the audio wiring harness in the headrest is connected to the speaker at one end and to the headrest rod at the other. This eliminates the need to connect the audio wiring harness to the wiring harness in the seatback, making it easier to remove the headrest from the seatback. When the front seatback is folded flat and connected to the rear seat cushion, it provides users with more sleeping space, helping to improve their sleeping experience.

[0043] In combination with the second aspect, in certain implementations of the second aspect, the other end of the audio wiring harness is connected to the inner wall of the headrest rod, and an insulating material is provided between the inner wall and the outer wall of the headrest rod.

[0044] Based on the above technical solution, by providing insulating material between the inner wall and the outer wall of the headrest rod, harm to the user during signal transmission can be avoided.

[0046] In combination with the third aspect, in certain implementations of the third aspect, the connector further includes a snap-fit ​​structure, and when the connector is inserted into the headrest rod, the snap-fit ​​structure is snap-fitted with the inner wall of the headrest rod.

[0047] In combination with the third aspect, in certain implementations of the third aspect, the seat back further includes an upper plug-in structure and a lower plug-in structure, the lower plug-in structure includes a transverse locking mechanism and a locking block structure, the lower plug-in structure is arranged on the outside of the headrest rod, when the headrest rod is pulled out from the seat back, the connector drives the lower plug-in structure to move and when the lower plug-in structure is inserted into the upper plug-in structure, the transverse locking mechanism is triggered to squeeze the locking block structure, so that the locking block structure is engaged with the clamping structure.

[0048] In combination with the third aspect, in certain implementations of the third aspect, the clamping structure includes a support arm and a spring, the upper end of the support arm rotates around a fixed point on the connector, the lower end of the support arm is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the connector.

[0049] In combination with the third aspect, in certain implementations of the third aspect, the seat back includes a lower plug-in structure, the lower plug-in structure includes a locking block structure and the lower plug-in structure is fixedly connected to the connector, the locking block structure is sleeved with the headrest rod or connected magnetically, when the headrest rod is pulled out of the seat back, the locking block structure drives the lower plug-in structure and the connector to move in a first direction, and the first direction is from the bottom of the seat to the top of the seat.

[0050] In combination with the third aspect, in certain implementations of the third aspect, the locking block structure includes a recessed portion, the seat back further includes an upper plug-in structure, the upper plug-in structure includes a transverse locking mechanism, the transverse locking mechanism cooperates with the recessed portion, and when the lower plug-in structure is inserted into the upper plug-in structure, the transverse locking mechanism squeezes the recessed portion to stop the lower plug-in structure and the connector from moving.

[0068] As mentioned earlier, with the advancement of intelligent vehicles, vehicles have evolved from being a means of transportation to a mobile vehicle that integrates travel, entertainment, and leisure. The headrests in vehicle seats currently on the market primarily provide simple support. The audio system within the vehicle is too simple, preventing users from experiencing each sound individually. A music headrest can provide users with a partitioned, independent experience. However, because the audio wiring harness in the music headrest is physically connected to the seat wiring harness in the seat back, the music headrest cannot be removed from the seat back. This prevents the seat back from reclining, impacting the user's sleeping experience.

[0069] The present invention provides a seat, headrest, and vehicle with a pluggable headrest structure that solves the problem of headrests being unable to be removed from seat backs. In sleep mode, the user can pull the headrest out of the seat back, allowing the front seat back to lie flat and connect with the rear seat cushion to create a larger sleeping space, thereby enhancing the user's sleep experience.

[0070] Figure 1 shows a schematic structural diagram of a seat 100 provided in an embodiment of the present application. As shown in Figure 1 , seat 100 includes a seat back 120, which includes a connector 122. Connector 122 includes a signal transmission structure 1221 and a seat wiring harness 1222. Signal transmission structure 1221 abuts against the inner wall of a headrest rod 111 in a headrest 110, and seat wiring harness 1222 is connected to signal transmission structure 1222.

[0071] Optionally, the seat back 120 further includes a headrest guide sleeve 121 , and the headrest rod 111 can be inserted into the headrest guide sleeve 121 and can also be pulled out from the headrest guide sleeve 121 .

[0072] Optionally, the position of the connector 122 in the seat back 120 is fixed.

[0073] For example, the headrest guide sleeve 121 includes an opening through which the headrest rod 111 can be inserted or removed. The connector 122 can be disposed below the opening.

[0074] Optionally, the signal transmission structure 1221 and the inner wall of the headrest rod 111 can be connected by magnetic force.

[0075] The seat wiring harness 1222 can transmit sound signals or electrical signals to the signal transmission structure 1221 , and the signal transmission structure 1221 transmits the signal to the audio wiring harness through the headrest rod 111 , thereby transmitting the signal to the audio in the headrest 120 through the audio wiring harness.

[0076] Optionally, the cross-sectional dimensions of the signal transmission structure 1221 match those of the inner wall of the headrest rod 111. This ensures that the signal transmission structure 1221 abuts the inner wall of the headrest rod 111, thereby enabling signal transmission. Furthermore, the headrest rod 111 can serve as a conductive carrier to connect the audio wiring harness and the seat wiring harness 1222.

[0077] Optionally, the connector 122 further includes a snap-fit ​​structure 1223 . When the connector 122 is in the first state, the snap-fit ​​structure 1223 is snap-fitted to the inner wall of the headrest rod 111 .

[0078] Optionally, the connector 122 is in a first state, including: the connector 122 is located in the inner wall of the headrest rod 111 .

[0079] Optionally, the snap-fit ​​structure 1223 is located below the signal transmission structure 1221 .

[0080] Optionally, the clamping structure 1223 includes a support arm 12231 and a spring 12232, the upper end of the support arm 12231 rotates around a point on the connector 122, the lower end of the support arm 12231 is fixedly connected to one end of the spring 12232, and the other end of the spring 12232 is fixedly connected to the connector 122.

[0081] For example, Figures 2 and 3 show a side view and a top view, respectively, of a connector 122 provided in an embodiment of the present application. Taking the signal transmission structure 1221 as an example of a retractable spring 12211, the connector 122 may include the retractable spring 12211, a seat harness 1222, and a snap-on structure 1223.

[0082] Optionally, the connector 122 includes a plurality of snap-fit ​​structures 1223 .

[0083] For example, as shown in FIG. 2 and FIG. 3 , the connector includes two clamping structures 1223 , and the two clamping structures 1223 can be symmetrically arranged.

[0084] Optionally, the connector 122 includes a plurality of retractable springs 12211 .

[0085] Exemplarily, as shown in FIG3 , the connector 122 may include four retractable springs 12211 .

[0086] Optionally, the seat back 120 also includes a first upper plug-in structure 123 and a first lower plug-in structure 124, the first lower plug-in structure 124 includes a first transverse locking mechanism 1241 and a first locking block structure 1242, the first lower plug-in structure 124 is arranged on the outside of the headrest rod 111, and when the connector 122 is in the second state, the connector 122 drives the first lower plug-in structure 124 to move and when the first lower plug-in structure 124 is inserted into the first upper plug-in structure 123, the first transverse locking mechanism 1241 is triggered to squeeze the first locking block structure 1242, so that the first locking block structure 1242 is engaged with the clamping structure 1223.

[0087] Optionally, the connector 122 is in the second state, including: the connector 122 moves upward along with the headrest rod 111 .

[0088] Optionally, the first upper plug-in structure 123 is located outside the first lower plug-in structure 124 , and a space is included between the first upper plug-in structure 123 and the headrest rod 111 , and the first lower plug-in structure 124 can move in the space.

[0089] Optionally, the transverse dimension between the first upper plug-in structure 123 and the headrest rod 111 is greater than or equal to the transverse dimension of the first lower plug-in structure 124 , so that the first lower plug-in structure 124 can move in the space.

[0090] Optionally, when the transverse dimension between the first upper plug-in structure 123 and the headrest rod 111 is greater than the transverse dimension of the first lower plug-in structure 124, the difference between the transverse dimension between the first upper plug-in structure 123 and the headrest rod 111 and the transverse dimension of the first lower plug-in structure 124 is less than or equal to a preset difference. In this way, when the dimension between the first upper plug-in structure 123 and the first lower plug-in structure 124 is small, it can be ensured that when the first lower plug-in structure 124 is inserted into the first upper plug-in structure 123, the first transverse locking mechanism 1241 can be squeezed by the first upper plug-in structure 123, thereby causing the first transverse locking mechanism 1241 to squeeze the first locking block structure 1242.

[0091] Optionally, the first upper plug-in structure 123 is fixedly connected to the headrest guide sleeve 121 .

[0092] For example, Figures 4 and 5 respectively illustrate schematic diagrams of the connector 122 provided in an embodiment of the present application, shown uninserted from the headrest rod 111 and inserted into the headrest rod 111. As can be seen, during the transition from the insertion of the connector 122 into the headrest rod 111, the retractable spring 12211 abuts against the inner wall of the headrest rod 111, and the spring 12232 in the engaging structure 1223 is compressed. This creates an interaction force between the support arm 12231 and the inner wall of the headrest rod 111, allowing the engaging structure 1223 to engage with the inner wall of the headrest rod 111, securing the connector 122 to the headrest rod 111. This ensures that when the user adjusts the height of the headrest 110, the connector 122 remains attached to the headrest 110 and moves with the movement of the headrest rod 111. At the same time, since the connector 122 is inserted into the inner wall of the headrest rod 111, the retractable spring 12211 can be abutted against the inner wall of the headrest rod 111, so that the seat wiring harness 1222, the retractable spring 12211, the headrest rod 111 and the audio wiring harness can be connected and conducted.

[0093] 6 shows a schematic diagram of the headrest rod 111 provided in an embodiment of the present application when it is pulled out of the headrest guide sleeve 121. When the headrest rod 111 is pulled out of the headrest guide sleeve 121, the first lower plug structure 124 is inserted into the first upper plug structure 123 under the drive of the plug connector 122. When the first lower plug-in structure 124 is inserted into the first upper plug-in structure 123, the spring in the transverse locking mechanism 1241 is compressed, thereby pushing the first locking block structure 1242 to move horizontally (for example, the left locking block structure moves to the right and the right locking block structure moves to the left). As a result, the first locking block structure 1242 can squeeze the clamping structure 1223, so that the interaction force between the support arm 12231 and the headrest rod 111 is released (or the interaction force between the support arm 12231 and the headrest rod 111 disappears). In other words, the clamping structure 1223 changes from being engaged with the headrest rod 111 to being engaged with the first locking block structure 1242. The headrest rod 111 can be smoothly removed from the headrest guide sleeve, and the connector 122 can remain in the seat back 120.

[0094] In the above embodiment, the plug connector 122 includes the snap-fit ​​structure 1223 as an example for explanation, but the present invention is not limited thereto. The plug connector 122 may also not include the snap-fit ​​structure 1223 .

[0095] For example, FIG7 and FIG8 respectively show a schematic diagram of the connector 122 provided in an embodiment of the present application not being inserted into the headrest rod 111 and another schematic diagram of the connector 122 being inserted into the headrest rod 111.

[0096] Optionally, the seat back 120 includes a second lower plug-in structure 126, the second lower plug-in structure 126 includes a second locking block structure 1261 and the second lower plug-in structure 126 is fixedly connected to the connector 122, the second locking block structure 1261 is sleeved with the headrest rod 111 or connected by magnetic force, when the second locking block structure 1261 is in the third state, the second locking block structure 1261 drives the second lower plug-in structure 126 and the connector 122 to move in a first direction, and the first direction is from the bottom of the seat to the top of the seat.

[0097] Optionally, the second locking block structure 1261 is in a third state, including: the headrest rod 111 is not pulled out from the seat back 120 .

[0098] Optionally, the second locking block structure 1261 includes a recessed portion 12611, and the seat back 120 also includes a second upper plug-in structure 125, and the second upper plug-in structure 125 includes a second transverse locking mechanism 1251, and the second transverse locking mechanism 1251 cooperates with the recessed portion 12611. When the second locking block structure 1261 is inserted into the second upper plug-in structure 125, the second transverse locking mechanism 1251 squeezes the recessed portion 12611 to stop the second lower plug-in structure 126 and the connector 122 from moving.

[0099] Optionally, one side of the second upper plug-in structure 125 is in contact with the headrest rod 111 .

[0100] Optionally, the second upper plug-in structure 125 can be fixedly connected to the headrest guide sleeve 121. When the second locking block structure 1261 is inserted into the second upper plug-in structure 125, the second transverse locking mechanism 1251 can compress the second locking block structure 1261, thereby stopping the movement of the second locking block structure 1261, the second lower plug-in structure 126, and the connector 122. In this way, the headrest rod 111 can be removed from the headrest guide sleeve 121.

[0101] Optionally, the second upper plug-in structure 125 can move within a certain range. When the second locking block structure 1261 is inserted into the upper plug-in structure 125, the second transverse locking mechanism 1251 can compress the second locking block structure 1261. At this time, the second upper plug-in structure 125, the second locking block structure 1261, the second lower plug-in structure 126, and the connector 122 can continue to move upward due to the interaction between the second locking block structure 1261 and the headrest rod 111. When the second upper plug-in structure 125 contacts the headrest guide sleeve 121, the second upper plug-in structure 125 stops moving, thereby causing the second locking block structure 1261, the second lower plug-in structure 126, and the connector 122 to stop moving. In this way, the headrest rod 111 can be pulled out of the headrest guide sleeve 121.

[0102] Optionally, a space is formed between the second upper plug-in structure 125 and the headrest rod 111, and the second locking block structure 1261 can move in the space. The second locking block structure 1261 cooperates with the second upper plug-in structure 125, so that the second locking block structure 1261 can be smoothly inserted into the second upper plug-in structure 125.

[0103] Optionally, the recessed portion 12611 is an opening provided on the second locking block structure 1261, and the size of the second transverse locking mechanism 1251 matches the size of the opening, so that when the second locking block structure 1261 is inserted into the second upper plug-in structure 125, the second transverse locking mechanism 1251 extends into the opening, thereby squeezing the second locking block structure 1261.

[0104] Optionally, the second lower plug-in structure 126 includes a space, and the plug-in component 122 can be accommodated in the space.
