TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a seat structure and a vehicle. BACKGROUND

[0002] The front row seats of the car currently prefer to use music headrests. The sound of the music headrest needs to be fixed inside the headrest and needs to be connected with a wire harness and a connector to connect the electrical signal to realize the function of playing music and the like. However, the wire harness and the connector of the music headrest usually need to be fixed inside the headrest and on the framework to meet the good electrical performance connection and ensure the normal sound output function.

[0003] In the related art, the wire harness and the connector arranged inside the headrest can easily cause inconvenience in adjusting the headrest up and down and taking the headrest off the seat. Therefore, how to improve the use convenience of the seat structure is a technical problem to be solved at present. SUMMARY

[0004] The present application provides a seat structure and a vehicle. The seat structure according to the present application improves the use convenience.

[0005] In order to achieve the above-mentioned purpose, the main technical scheme adopted by the present application includes: In a first aspect, the present application provides a seat structure, comprising a headrest rod, a first wiring terminal, a second wiring terminal, a seat framework and a sleeve: the headrest rod is sleeved with the first wiring terminal, and the headrest rod is fixedly connected with the first wiring terminal through a first locking member; at least part of the second wiring terminal is sleeved on the headrest rod, and the second wiring terminal is selectively fixedly connected with the headrest rod through a second locking member; the sleeve is fixedly arranged on the seat framework, and the headrest rod and the second wiring terminal are movably arranged in the sleeve along the axial direction of the sleeve.

[0006] According to the seat structure provided by the first aspect of the present application, the second locking member can lock the second wiring terminal and the headrest rod to prevent the first wiring terminal and the second wiring terminal from being disconnected during the up and down movement of the headrest rod, so that the stable assembly of the headrest rod and the wiring terminal can be realized, and the assembly position of the second wiring terminal can be flexibly adjusted to adapt to different wiring requirements, greatly improving the assembly flexibility and use convenience of the headrest. At the same time, the double fixing structure of the first locking member and the second locking member can effectively avoid the disconnection and looseness of the first wiring terminal and the second wiring terminal during the up and down movement of the headrest rod, guarantee the reliability and stability of the wiring connection, reduce the occurrence of problems such as poor contact and line disconnection, and the overall structure is convenient to disassemble and assemble without the need for complex tools.

[0007] Optionally, the second wiring terminal comprises a first segment and a second segment connected in sequence, and the first segment is sleeved on the headrest rod. The second locking member comprises a first body part and a first elastic part, the first body part is clamped between the sleeve and the first section along the radial direction of the sleeve, the first section is provided with a first opening, the headrest rod is provided with a first groove, and the first elastic part is selectively matched with the first opening and the first groove.

[0008] In the above scheme, the coaxial and accurate butt joint of the second wiring terminal and the headrest rod can be realized by sleeving the first section on the headrest rod, which helps to improve the wiring stability, and the first body part can be fixed and installed by relying on the radial clamping of the sleeve and the first section, so that the structure is compact. At the same time, the cooperation of the first elastic part, the first opening and the first groove can conveniently realize the quick locking and fixing or unlocking and sliding of the second wiring terminal and the headrest rod, the operation is simple and does not require special tools, the elastic part is clamped into the groove to form reliable limiting when locking, preventing the terminal from loosening when the headrest rod is lifted and ensuring stable wiring conduction.

[0009] Optionally, the first elastic part, the first opening and the first groove are two, the two first openings are oppositely arranged along the radial direction of the sleeve, the two first grooves are oppositely arranged, and each first elastic part is selectively matched with the corresponding first opening and first groove.

[0010] In the above scheme, a bilateral symmetrical locking structure can be formed, so that the second wiring terminal is balanced in force, the locking firmness and stability of the second wiring terminal and the headrest rod are greatly improved, the terminal deflection, loosening and headrest rod rotation caused by unilateral locking are effectively reduced, the wiring conduction is reliably ensured, at the same time, the two first elastic parts on both sides are synchronously clamped into or separated from the corresponding matching positions, the unlocking and adjustment are smooth and non-stuck, the locking positioning is accurate, the stress loss can be dispersed, and the service life of the locking member is prolonged; at the same time, self-centering is realized by relying on bilateral symmetrical cooperation, the coaxiality of the second wiring terminal and the headrest rod is ensured, the wiring is prevented from being offset to pull the line, and the structure is adapted to the compact space in the radial direction of the sleeve, and the locking reliability, adjustment convenience and structural durability are considered.

[0011] Optionally, the outer diameter of the first section is smaller than the outer diameter of the second section to form a first step surface. The sleeve comprises a third section and a fourth section connected in sequence, the outer diameter of the third section is smaller than the outer diameter of the fourth section to form a second step surface, and the first step surface is selectively abutted with the second step surface.

[0012] In the above scheme, the abutment of the step surfaces provides accurate axial limiting for the axial movement of the second wiring terminal, avoiding the separation of the second wiring terminal from the sleeve to cause jamming and line pulling, so that the second wiring terminal can be kept in the sleeve at all times, ensuring that the second wiring terminal is always within the protection range of the sleeve, preventing the terminal from being exposed to bumps and dust and foreign matter, and further protecting the terminal structure and wiring contact from damage.

[0013] Optionally, the seat structure also includes a third locking element disposed in the second section and configured to optionally restrict axial movement of the second terminal block along the sleeve.

[0014] In the above solution, by locking the relative position of the second terminal and the sleeve with the third locking component, the slight slippage and loosening of the second terminal under the conditions of frequent lifting and lowering of the headrest rod and seat vibration can be reduced. This fundamentally avoids faults such as line pulling, contact offset and poor contact caused by terminal slippage, and ensures the continuity and stability of wiring.

[0015] Optionally, the third locking member includes a second body portion and a second elastic portion. Along the radial direction of the sleeve, the second body portion is sandwiched between the sleeve and the second section. The sleeve is provided with a second opening, and the second elastic portion can optionally engage with the second opening.

[0016] In the above scheme, the cooperation between the second elastic part and the second opening can realize the rapid locking and unlocking of the axial movement of the second terminal. When locked, the elastic part is inserted into the second opening to form a rigid radial limit, which can restrict the sliding of the second terminal along the sleeve axis, reduce terminal displacement under vibration and lifting conditions, avoid line pulling and contact loosening, and ensure stable wiring continuity. When unlocked, the elastic part can be disengaged from the second opening to smoothly adjust the terminal position. The operation is simple and does not require special tools, which greatly improves the convenience of use.

[0017] Optionally, there are multiple second elastic parts and multiple second openings. Multiple second elastic parts are spaced apart along the circumference of the sleeve, and each second elastic part can selectively cooperate with a corresponding second opening.

[0018] In the above scheme, multiple second elastic parts and second openings are arranged at intervals along the circumference of the sleeve to form a multi-point radial locking structure. This greatly improves the axial limiting firmness and circumferential anti-rotation effect of the third locking component on the second terminal. The multi-point synchronous engagement allows the second section to be subjected to uniform force, completely preventing the terminal from sliding along the axial direction of the sleeve and rotating around the circumference, avoiding the offset of the wiring contacts, the twisting and wear of the line, and improving the connection stability.

[0019] Optionally, a guide groove is provided on the inner wall of the sleeve, the guide groove extends along the axial direction of the sleeve, and the second elastic part is slidably disposed in the guide groove.

[0020] In the above solution, the guide groove can provide precise axial sliding guidance for the second section, ensuring that the second terminal block is adjusted without swaying or jamming along the sleeve axis, and always maintains coaxiality with the headrest rod. This avoids wire twisting and contact offset caused by the skewness of the second terminal block, ensuring smooth adjustment and wiring stability. At the same time, the guide groove can form a circumferential anti-rotation limit, completely eliminating circumferential rotation of the second terminal block when it moves with the headrest rod, preventing misalignment of the elastic part and the opening, and locking failure. It also avoids wire entanglement and wear, further enhancing the reliability of wiring continuity.

[0021] Optionally, the seat structure also includes a headrest, which includes a headrest body and a speaker. The headrest body is located at the end of the headrest rod away from the seat frame, and the speaker is located inside the headrest body and is electrically connected to the first terminal block.

[0022] In the above solution, the headrest body is assembled to the end of the headrest rod to form a support. At the same time, the headrest body has a built-in speaker and is electrically connected to the first terminal block, realizing the integration of the headrest support function and the audio playback function. There is no need to install an external speaker. While simplifying the overall structure of the seat, the speaker is brought closer to the ears of the driver and passengers, improving the surround sound and auditory experience of the audio playback.

[0023] Secondly, embodiments of this application provide a vehicle including the seat structure described in any of the embodiments.

[0024] According to the second aspect of the present application, the vehicle, having the seat structure described in any embodiment, can achieve smooth lifting and lowering adjustment of the headrest rod, and can reduce the occurrence of loosening of the first and second wiring terminals through the limiting of the second locking member, ensuring the continuous and stable power supply and signal transmission of the audio system, effectively avoiding problems such as sound interruption, noise, and poor wiring contact under vehicle driving bumps and vibrations, and improving the reliability and convenience of the vehicle audio system.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0034] High-end car models currently favor the use of music headrests for their front seats. The speakers in these headrests need to be fixed inside, requiring wiring harnesses and connectors to receive electrical signals and enable music playback. However, ensuring proper electrical connection and sound output from the speakers, while maintaining the wiring harnesses and connectors within the headrest and frame, presents challenges for adjusting the headrest's height and removing it from the seat.

[0035] Currently, "magnetic" quick-connect devices and "conductive mechanical structures" have appeared on the market. The magnetic design may cause magnetic interference that affects the EMC performance of the whole vehicle, while the mature conductive mechanical structure has more parts and is more complex to assemble.

[0036] Therefore, improving the ease of use of seat structures is a technical problem that urgently needs to be solved.

[0037] In view of this, in order to improve the ease of use of the seat structure, this application proposes a seat structure in which a first terminal 200 is sleeved on a headrest rod 100, and the headrest rod 100 and the first terminal 200 are fixedly connected by a first locking member 600. At least a portion of a second terminal 300 is sleeved on the headrest rod 100, and the second terminal 300 is selectively fixedly connected to the headrest rod 100 by a second locking member 700. The second locking member 700 can lock the second terminal 300 to the headrest rod 100 to prevent the first terminal 200 and the second terminal 300 from colliding during the up and down movement of the headrest rod 100. The headrest rod 100 and the second terminal 300 can be detached, thus achieving a stable assembly and allowing for flexible adjustment of the assembly position of the second terminal 300 to accommodate different wiring requirements, significantly improving the assembly flexibility and ease of use of the headrest. At the same time, the dual fixing structure of the first locking member 600 and the second locking member 700 effectively prevents the headrest rod 100 from detaching from or loosening from the first terminal 200 and the second terminal 300 when moving up and down, ensuring the reliability and stability of the wiring connection, reducing the occurrence of problems such as poor contact and wire detachment, and the overall structure is easy to disassemble and assemble without complicated tools.

[0038] The following is based on the appendix Figure 1 -Appendix Figure 5 This application describes the seat structure and vehicle proposed in its embodiments.

[0039] According to the first aspect of the embodiment of this application, a seat structure is provided. Please refer to... Figure 1 and Figure 2 It includes a headrest rod 100, a first terminal block 200, a second terminal block 300, a seat frame 400, and a sleeve 500.

[0040] The headrest rod 100 is fitted with the first terminal 200, and the headrest rod 100 and the first terminal 200 are fixedly connected by the first locking member 600. Specifically, the first terminal 200 can be used as the female terminal of the audio wiring, the headrest rod 100 can be fitted on the outside of the first terminal 200, and the first locking member 600 can prevent the headrest rod 100 and the first terminal 200 from sliding or loosening relative to each other. The first locking member 600 can fix the headrest rod 100 and the first terminal 200 together to ensure the reliability of the audio wiring and avoid poor circuit contact due to loose terminals during use of the headrest.

[0041] In a specific embodiment, the first locking member 600 is constructed as a protrusion on the first terminal 200, and the headrest rod 100 is provided with a fixing hole that mates with the protrusion, thereby fixing the first terminal 200 and the headrest rod 100.

[0042] The sleeve structure fits the axial layout of the headrest rod 100, resulting in a high degree of fit. No additional adapter structure is required, simplifying the wiring and assembly process. At the same time, it can provide a precise docking reference for the second terminal block 300, avoiding wiring misalignment.

[0043] At least a portion of the second terminal block 300 is sleeved on the headrest rod 100. The second terminal block 300 is selectively fixedly connected to the headrest rod 100 by the second locking member 700. It is understood that the second terminal block 300 can be used as the male terminal of the audio wiring. The second terminal block 300 can cooperate with the first terminal block 200 to achieve electrical connection, thereby providing power or transmitting signals to electronic components such as audio equipment.

[0044] Meanwhile, the second terminal 300 can be freely adjusted along the axial direction of the headrest rod 100 to adapt to wiring requirements of different line lengths and headrest lifting strokes. This prevents the first terminal 200 and the second terminal 300 from disengaging when the headrest rod 100 moves, ensuring wiring reliability. Furthermore, both the first terminal 200 and the second terminal 300 are coaxially sleeved on the headrest rod 100, enabling coaxial connection, reducing the occurrence of line bending and pulling, and improving the connection convenience and reliability of the first terminal 200.

[0045] The sleeve 500 is fixed to the seat frame 400. Along the axial direction of the sleeve 500, the headrest rod 100 and the second terminal 300 are movably disposed within the sleeve 500. The sleeve 500 connects the seat frame 400 to form a stable support, providing precise guidance for the axial movement of the headrest rod 100 and the second terminal 300, ensuring that the headrest rod 100 moves in a straight line during lifting and lowering, reducing the occurrence of swaying and jamming, and improving the smoothness of headrest adjustment.

[0046] Meanwhile, the sleeve 500 encapsulates the headrest rod 100 and the second terminal block 300 inside, isolating them from external dust, debris, and bumps during seat use, protecting the terminal blocks and wiring from damage, and preventing exposed wiring from being snagged or worn.

[0047] In addition, the sleeve 500 receives the radial load of the headrest rod 100 and transmits it to the seat frame 400, avoiding direct contact between the headrest rod 100 and the frame, thus preventing wear. At the same time, it does not occupy extra space in the seat, simplifies the overall layout of the seat, improves structural compactness, reduces assembly difficulty, and achieves integrated headrest lifting and wiring functions.

[0048] In a specific embodiment, the sleeve 500 is divided into two parts: the sleeve body and the guide sleeve. The sleeve body and the guide sleeve are respectively fixed to the seat frame 400 by the mounting bracket. The headrest rod 100 slides in the guide sleeve, and the second terminal 300 slides in the sleeve body. This arrangement helps to improve the coaxiality of the headrest rod 100 during installation and vertical adjustment, and further improves the ease of use.

[0049] In other embodiments, please refer to Figure 1 and Figure 2 The second terminal 300 includes a first segment 310 and a second segment 320 connected in sequence, with the first segment 310 sleeved on the headrest rod 100; The second locking member 700 includes a first body portion 710 and a first elastic portion 720. Along the radial direction of the sleeve 500, the first body portion 710 is sandwiched between the sleeve 500 and the first segment 310. The first segment 310 is provided with a first opening 311, and the headrest rod 100 is provided with a first groove 101. The first elastic portion 720 can selectively cooperate with the first opening 311 and the first groove 101.

[0050] In the above scheme, the second terminal 300 and the headrest rod 100 can be precisely connected coaxially by the first segment 310 sleeved on the headrest rod 100, which helps to improve the stability of the wiring. The second locking member 700 can be fixedly installed by the sleeve 500 and the first segment 310 radially clamping the first body part 710. The structure is compact. At the same time, the cooperation between the first elastic part 720, the first opening 311, and the first groove 101 can easily realize the quick locking and fixing or unlocking and sliding of the second terminal 300 and the headrest rod 100. The operation is simple and no special tools are required. When locking, the elastic part is inserted into the groove to form a reliable limit, preventing the terminal from loosening when the headrest rod 100 is raised and lowered, and ensuring stable wiring.

[0051] It also utilizes the self-resetting characteristics of the elastic structure to achieve automatic locking, improving adjustment and assembly efficiency. The overall structure has a high degree of integration, does not occupy extra space, and balances connection reliability, adjustment convenience and lightweight structure.

[0052] In a specific embodiment, when the headrest rod 100 is fitted with the first terminal 200, the first elastic part 720 extends into the first opening 311 and abuts against the inner wall of the first groove 101, thereby realizing the connection and fixation between the first terminal 200 and the headrest rod 100.

[0053] When the first terminal 200 and the headrest rod 100 are disengaged, the first elastic part 720 can still extend into the first opening 311, and at this time the first body part 710 can still be fitted onto the outer peripheral wall of the first section 310.

[0054] In a specific embodiment, the projections of the first body portion 710 and the first elastic portion 720 along the axial direction of the headrest rod 100 can be annular, and the second locking member can be an annular clamp.

[0055] In a specific embodiment, along the axial direction of the headrest rod 100, the projections of the first body portion 710 and the first elastic portion 720 can be an open annulus, and the second locking member can be an open annular clamp.

[0056] In other embodiments, there are two first elastic portions 720, two first openings 311, and two first grooves 101 arranged opposite each other along the radial direction of the sleeve 500. Each first elastic portion 720 may selectively engage with the corresponding first opening 311 and first groove 101.

[0057] In the above scheme, a double-sided symmetrical locking structure can be formed, so that the second terminal 300 is subjected to balanced force, which greatly improves the locking firmness and stability of the second terminal 300 and the headrest rod 100, effectively reduces the occurrence of terminal misalignment, loosening and rotation of the headrest rod 100 caused by unilateral locking, and ensures reliable wiring. At the same time, the two first elastic parts 720 on both sides simultaneously engage or disengage from the corresponding mating positions, and the unlocking adjustment is smooth and without jamming, and the locking positioning is accurate.

[0058] In addition, it can disperse stress loss and extend the service life of the locking components; at the same time, it relies on the symmetrical cooperation on both sides to achieve self-centering, ensuring the coaxiality of the second terminal 300 and the headrest rod 100, avoiding wiring offset and pulling of the line, and the structure is suitable for the radial compact space of the matching sleeve 500, taking into account the locking reliability, adjustment convenience and structural durability.

[0059] In other embodiments, please refer to Figure 2 , Figure 3 and Figure 4 The outer diameter of the first segment 310 is smaller than the outer diameter of the second segment 320 to form the first step surface 312; The sleeve 500 includes a third segment 510 and a fourth segment 520 connected in sequence. The outer diameter of the third segment 510 is smaller than the outer diameter of the fourth segment 520 to form a second stepped surface 511. The first stepped surface 312 may optionally abut against the second stepped surface 511.

[0060] In the above scheme, the abutting cooperation between the first step surface 312 and the second step surface 511 provides a precise axial limit for the second terminal 300 to move along the axial direction of the sleeve 500, thereby preventing the second terminal 300 from disengaging from the sleeve 500 and causing jamming or wire pulling.

[0061] In other words, the abutting fit between the first step surface 312 and the second step surface 511 can provide precise axial limit for the second terminal 300 to move axially along the sleeve 500. This can fundamentally prevent the second terminal 300 from coming out of the inner cavity of the sleeve 500 when it moves with the headrest rod 100, completely eliminate interference between the second terminal 300 and other structures of the seat after it comes out, ensure that the headrest rod 100 can rise and fall smoothly and without obstruction throughout the entire process, and avoid adjustment failure and component wear caused by jamming.

[0062] At the same time, it can strictly limit the axial movement boundary of the second terminal 300, prevent the terminal from excessively sliding and causing the wiring to be excessively pulled or bent, effectively protect the insulation layer of the wiring and the wiring joint, avoid the wiring from cracking, breaking, poor contact and other faults caused by pulling, and ensure the conductivity stability and service life of the seat wiring system.

[0063] This design secures the second terminal 300 within the sleeve 500, ensuring that the second terminal 300 is always within the protective range of the sleeve 500, preventing the exposed terminal from being bumped or exposed to dust and debris, and further protecting the terminal structure and wiring contacts from damage.

[0064] In addition, the clear limit boundary can prevent excessive misalignment between the second terminal 300 and the first terminal 200, maintain the coaxial connection of the two terminals, avoid poor contact caused by the offset of the wiring contacts, and take into account both adjustment flexibility and wiring reliability. There is no need to add additional limit blocks or other components. The limit is achieved by relying on the structure of the step surface itself, which simplifies the structural design while improving the accuracy and durability of the limit.

[0065] The stepped structure of the first step surface 312 and the second step surface 511 forms a physical anti-foolproof system, which can quickly calibrate the assembly alignment of the second terminal 300 and the sleeve 500, greatly improving assembly efficiency and eliminating the need for additional measurement and debugging.

[0066] When the first step surface 312 and the second step surface 511 come into contact, they can disperse the axial force on the second terminal 300, avoid local pressure deformation, and enhance the connection stability between the second terminal 300 and the sleeve 500. At the same time, the stepped outer diameter design is adapted to the radial compact space of the headrest rod 100 and the sleeve 500, without occupying extra assembly space, and has a high degree of structural integration.

[0067] Meanwhile, the stepped structure is easy to process, requiring no additional limiting components, simplifying the overall structural design and reducing manufacturing costs.

[0068] In other embodiments, please refer to Figure 1 and Figure 2 The seat structure also includes a third locking element 800, which is disposed in the second section 320 and configured to selectively restrict the axial movement of the second terminal 300 along the sleeve 500.

[0069] In the above solution, by locking the relative position of the second terminal 300 and the sleeve 500 with the third locking member 800, the slight slippage and loosening of the second terminal 300 under the conditions of frequent lifting and lowering of the headrest rod 100 and seat vibration can be reduced, fundamentally avoiding faults such as line pulling, contact offset and poor contact caused by terminal slippage, and ensuring the continuity and stability of wiring.

[0070] Meanwhile, when the third locking component 800 is unlocked, it does not affect the normal adjustment of the second terminal 300 along the axial direction of the sleeve 500, adapting to the wiring requirements of different headrest heights. When locked, it forms a rigid limit, meeting the ultimate stability requirements in fixed use scenarios and ensuring adjustment flexibility.

[0071] In addition, the third locking component 800 is located in the second section 320, away from the compact mating area inside the sleeve 500, providing ample space for disassembly and assembly. It can quickly complete locking or unlocking operations without disassembling core components such as the headrest rod 100 and the sleeve 500, greatly improving the convenience of later debugging and maintenance. Moreover, this structure is based on the second section 320 body and does not require modification of the original structure of the sleeve 500 and the headrest rod 100. It does not occupy the internal radial space of the sleeve 500 and does not affect the smoothness of the lifting and lowering of the headrest rod 100.

[0072] In a specific embodiment, when the second terminal 300 and the headrest rod 100 move together in the sleeve 500, the third locking member 800 abuts against the inner wall of the sleeve 500 and slides on the inner wall of the sleeve 500. When the second terminal 300 and the headrest rod 100 move to a specific position, that is, when the third locking member 800 slides to the locked position, the third locking member 800 can lock the second terminal 300 and the sleeve 500, thereby preventing the second terminal 300 from moving along the axial direction of the sleeve 500.

[0073] In other embodiments, please refer to Figure 1 and Figure 2 The third locking member 800 includes a second body portion 810 and a second elastic portion 820. Along the radial direction of the sleeve 500, the second body portion 810 is sandwiched between the sleeve 500 and the second section 320. The sleeve 500 is provided with a second opening 530. The second elastic portion 820 can selectively cooperate with the second opening 530.

[0074] In the above scheme, the cooperation between the second elastic part 820 and the second opening 530 can realize the rapid locking and unlocking of the axial movement of the second terminal 300. When locked, the elastic part is engaged in the second opening 530 to form a rigid radial limit, which can restrict the sliding of the second terminal 300 along the axial direction of the sleeve 500, reduce terminal displacement under vibration and lifting conditions, avoid line pulling and contact loosening, and ensure stable wiring continuity. When unlocked, the elastic part is disengaged from the second opening 530 to smoothly adjust the terminal position. The operation is simple and does not require special tools, which greatly improves the convenience of use.

[0075] Meanwhile, the radial clamping installation method allows the force on the locking component to be distributed radially along the sleeve 500, with no axial stress concentration, making it less prone to deformation and failure. Combined with the self-resetting characteristics of the elastic part, the locking fit is high and the limiting accuracy is strong. It can also form a circumferential limit on the second body part 810 with the help of the inner wall of the sleeve 500, preventing the locking component from rotating and deviating, and further improving the limiting reliability.

[0076] In other embodiments, there are multiple second elastic portions 820 and second openings 530. Multiple second elastic portions 820 are spaced apart along the circumference of the sleeve 500, and each second elastic portion 820 can selectively cooperate with a corresponding second opening 530.

[0077] In the above scheme, the second elastic part 820 and the second opening 530 are both set as multiple and are arranged at intervals along the circumference of the sleeve 500 to cooperate with each other, which can form a circumferential multi-point radial locking structure. This greatly improves the axial limiting firmness of the third locking part 800 on the second terminal 300 and the circumferential anti-rotation effect. The multi-point synchronous engagement can make the second section 320 evenly stressed, completely eliminating the terminal from sliding along the axial direction of the sleeve 500 and rotating around the circumference, avoiding the offset of the wiring contacts, the twisting and wear of the line, and improving the connection stability.

[0078] Multiple sets of second elastic parts 820 cooperate with corresponding second openings 530 to achieve precise locking and positioning of the second terminal 300 in multiple radial positions of the sleeve 500, improving ease of use.

[0079] Meanwhile, the circumferential spacing layout disperses the force loss of a single locking unit, reduces the probability of fatigue deformation and wear failure of the elastic part, and significantly extends the service life of the third locking component 800.

[0080] In other embodiments, please refer to Figure 5 The inner wall of the sleeve 500 is provided with a guide groove 540, which extends along the axial direction of the sleeve 500, and the second elastic part 820 is slidably disposed in the guide groove 540.

[0081] In the above scheme, the guide groove 540 can provide precise axial sliding guidance for the second section 320, ensuring that the second terminal 300 is adjusted without swaying or jamming when it is raised and lowered along the sleeve 500, and always maintains coaxiality with the headrest rod 100, avoiding wire twisting and contact offset caused by the misalignment of the second terminal 300, and ensuring smooth adjustment and wiring stability.

[0082] Meanwhile, the guide groove 540 can form a circumferential anti-rotation limit, completely eliminating the circumferential rotation of the second terminal 300 when it moves with the headrest rod 100, preventing the elastic part from misaligning with the opening and the locking failure, while avoiding wire entanglement and wear, and further enhancing the reliability of wiring continuity.

[0083] In addition, the guide groove 540 can also form a structural protection for the second elastic part 820, preventing the elastic part from directly rubbing and bumping against the inner wall of the sleeve 500 during sliding and locking, reducing wear and deformation of the elastic part, extending the service life of the locking part, and making the structure compact and integrated, easy to process. The guide groove 540 can also precisely limit the sliding path of the second elastic part 820, ensuring that the elastic part is always aligned with the second opening 530, improving the accuracy and convenience of locking and engaging, and taking into account the smoothness of adjustment, the reliability of locking, the durability of structure and overall compatibility.

[0084] In other embodiments, please refer to Figure 1 and Figure 2 The seat structure also includes a headrest 900, which includes a headrest body and a speaker. The headrest body is located at the end of the headrest rod 100 away from the seat frame 400, and the speaker is located inside the headrest body. The speaker is electrically connected to the first terminal 200.

[0085] In the above solution, the headrest body is assembled to the end of the headrest rod 100 to form a support. At the same time, the headrest body has a built-in speaker and is electrically connected to the first terminal 200, realizing the integration of the headrest support function and the audio playback function. There is no need to install an external speaker. While simplifying the overall structure of the seat, the speaker is brought closer to the ears of the driver and passengers, improving the surround sound and auditory experience of the audio playback.

[0086] The audio system draws power from the first terminal 200 and is powered through the headrest rod 100 to achieve concealed wiring, avoiding snagging and wear caused by exposed wiring, making the seat wiring neater and improving the overall aesthetics.

[0087] The secure connection between the headrest rod 100 and the wiring terminal ensures the continuity and stability of the audio power supply and signal transmission, eliminating problems such as sound interruption and noise during headrest height adjustment. Furthermore, the built-in headrest body utilizes the headrest structure to form an acoustic cavity, optimizing audio propagation. Simultaneously, the headrest body protects the audio system from impacts and dust, extending its lifespan. The overall structure enriches the seat's functionality without altering the core layout or affecting the headrest height adjustment function, significantly enhancing driving comfort and entertainment experience while balancing practicality, ease of use, and structural compatibility.

[0088] Secondly, embodiments of this application provide a vehicle including the seat structure described in any of the embodiments.

[0089] According to the second aspect of the present application, the vehicle, having the seat structure described in any embodiment, can achieve smooth lifting and lowering adjustment of the headrest rod 100, and can reduce the occurrence of loosening of the first terminal 200 and the second terminal 300 through the limiting of the second locking member 700, ensuring the continuous and stable power supply and signal transmission of the audio system, effectively avoiding problems such as sound interruption, noise, and poor wiring contact under vehicle driving bumps and vibrations, and improving the reliability and convenience of the vehicle audio system.
