[0034] 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, and 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.

[0035] like Figures 1-3 As shown, this application embodiment provides a seat, including a seat body, a headrest 30, a first connector 40, and a second connector 50; a plug-in seat 101 extending inside the seat body is provided at the top of the seat body, the plug-in seat 101 has a guide channel extending vertically, and the top of the guide channel is an opening; the headrest 30 integrates electrical units such as audio equipment, and the headrest 30 is provided with a headrest guide rod 301, which can be plugged into the guide channel; the first connector 40 is disposed on the headrest guide rod 301 and electrically connected to the electrical units in the headrest 30, the first connector 40 on the headrest guide rod 301... Driven by 1, it can slide along the guide channel. Specifically, the headrest guide rod 301 is hollow and has wiring, and the first connector 40 is fixed to the end of the headrest guide rod 301; the second connector 50 is set in the guide channel and electrically connected to the wiring in the seat body. The first connector 40 can be plugged into the second connector 50 and electrically connected; wherein, the plug-in seat is provided with a first limiting structure and a second limiting structure. The first limiting structure limits the second connector 50 in the insertion direction of the first connector 40, and the second limiting structure limits the second connector 50 in the withdrawal direction of the first connector 40.

[0036] With this configuration, the power supply units, such as the audio system, are integrated into the headrest 30 and connected by wiring. A first connector 40 for connection is provided at the end of the wiring. The seat body has a plug-in socket 101 providing a plug-in point for the headrest guide rod 301. The seat body also has wiring for supplying power to the power supply units in the headrest 30, with a second connector 50 for connection at the end of the wiring. Since the first connector 40 is located on the headrest guide rod 301 and the second connector 50 is arranged in the guide channel of the plug-in socket 101, the headrest guide rod 301 is inserted into the guide channel. At the same time, the first connector 40 also moves under the drive of the headrest guide rod 301, and pushes the second connector 50 against the first limiting structure until the first connector 40 and the second connector 50 are plugged in and electrically connected. When the headrest 30 needs to be removed, during the process of pulling out the headrest guide rod 301, the first connector 40 drives the second connector 50 upward and is pushed against the second limiting structure until the first connector 40 and the second connector 50 are disengaged. This solves the problem in the prior art of how the headrest 30 of the vehicle seat can have a quick disassembly and assembly function while having a music function.

[0037] Furthermore, the position restriction of the second connector 50 relies on the first and second limiting structures, thus making it easier to control production and design costs, which is beneficial for product development.

[0038] It should be noted that there are generally two headrest guide rods 301 and two plug-in sockets 101. The headrest guide rods 301 and plug-in sockets 101 on both sides can use the design scheme provided in this application, or only one side of the headrest guide rods 301 and plug-in sockets 101 can use the design scheme provided in this application, while the other side uses the conventional design in the prior art.

[0039] In some optional embodiments, the connector 101 is provided with a snap-fit ​​structure capable of engaging the headrest guide rod 301, so that the headrest guide rod 301 can slide and be fixed along the connector 101; a sliding interval is formed between the first limiting structure and the second limiting structure, so that the second connector 50 can slide with the first connector 40 within the sliding interval. It should be noted that the side wall of the headrest guide rod 301 is provided with multiple spaced slots, and the snap-fit ​​structure can engage with the slots. The snap-fit ​​structure can adopt conventional designs in the prior art.

[0040] In this configuration, considering that the headrest 30 in existing vehicle seats has a height adjustment requirement, in order to adapt to this design, the sliding space of the second connector 50 is constrained in the guide channel by controlling the spacing design between the first limiting structure and the second limiting structure, so that the second connector 50 can follow the first connector 40 to achieve position adjustment.

[0041] In some alternative embodiments, the first limiting structure is a bottom stop 102 that blocks the second connector 50. The bottom stop 102 can specifically be a mesh structure, frame structure, or solid structure connected to the bottom of the connector 101. This structure is simple to implement and facilitates cost control.

[0042] Of course, in addition to the above methods, it is also feasible to have a protrusion on the second connector 50 and a groove on the inner wall of the guide channel to accommodate the protrusion, with the closed end of the groove serving as the first limiting structure to stop the protrusion.

[0043] In some other alternative embodiments, the second limiting structure is a top stop 103 that blocks the second connector 50, and the orthographic projection of the top stop 103 does not overlap with the orthographic projection of the first connector 40 in the extension direction of the guide channel, that is, the top stop 103 and the first connector 40 are offset to allow the first connector 40 to pass through.

[0044] Furthermore, in some preferred embodiments, the top stop 103 is continuously or dispersedly distributed around the center line of the guide channel so that the first connector 40 passes through the center of the top stop 103.

[0045] With this configuration, the top stop 103 encloses a narrow section in the guide channel, reducing the local passage area of ​​the guide channel. The top stop 103 forms a circumferential limit on the first connector 40, and plays an auxiliary alignment role when the first connector 40 is about to be inserted into the second connector 50, which is conducive to accurate insertion into the second connector 50. Moreover, the top stop 103 is equivalent to forming a circumferential limit on the end of the headrest guide rod 301, so that even if the headrest guide rod 301 has a certain length, it is not easy to wobble in the insertion seat 101, thus improving the user's quality perception.

[0046] Furthermore, in some optional embodiments, the inner sidewall of the top stop 103 is provided with vertically extending protrusions, which are strip-shaped bodies that protrude relative to the inner sidewall of the top stop 103. Multiple protrusions are provided and distributed around the center line of the guide channel. The sidewall of the first connector 40 contacts and slides with the protrusions to form a damped sliding fit.

[0047] With this configuration, when the multiple protrusions slide in contact with the first connector 40, a small air channel is formed between adjacent protrusions. When the first connector 40 passes through the top stop 103, air damping is generated. This not only helps the first connector 40 slide smoothly, but also prevents the first connector 40 from disengaging from the plug socket 101 at the moment the first connector 40 and the second connector 50 are pulled apart, ensuring a safe operating feel when the headrest 30 is pulled out.

[0048] Of course, in addition to the above methods, it is also feasible to have a protrusion on the second connector 50 and a groove on the inner wall of the guide channel to accommodate the protrusion, with the closed end of the groove serving as a second limiting structure to stop the protrusion.

[0049] In some alternative embodiments, the plug-in base 101 is composed of two parts. The plug-in base 101 includes a guide rod cylinder 1011 and a slide rail cylinder 1012. The slide rail cylinder 1012 is disposed below the guide rod cylinder 1011 and communicates with the guide rod cylinder 1011 to form a guide channel in the guide rod cylinder 1011 and the slide rail cylinder 1012. The headrest guide rod 301 can slide along the guide rod cylinder 1011. The second connector 50 is slidably connected in the slide rail cylinder 1012, and the slide rail cylinder 1012 is provided with a first limiting structure and a second limiting structure. Specifically, the top opening of the slide rail cylinder 1012 is provided with a second limiting structure, and the bottom end of the slide rail cylinder 1012 is provided with a first limiting structure.

[0050] This configuration and modular design allow the guide rod cylinder 1011 to use the conventional design in the existing technology, which means it meets the functional requirement of being plugged into the headrest guide rod 301. In this way, only the slide rail cylinder 1012 structure needs to be added to the guide rod cylinder 1011, which helps to control production and development costs.

[0051] It should be noted that, in conjunction with the aforementioned embodiments, the buckle structure can be set on the guide rod cylinder 1011; preferably, the slide rail cylinder 1012 is integrally connected with the bottom stop body 102 and the top stop body 103.

[0052] Furthermore, in some optional embodiments, the slide rail 1012 is fixedly connected to the seat back frame, which may be by welding. The guide rod 1011 can use existing installation methods.

[0053] In some other specific embodiments, the first connector 40 is a male connector and the second connector 50 is a female connector. With this configuration, the male connector is generally smaller than the female connector. Designing the first connector 40 as a male connector makes it easier to reduce its size and facilitates a design where the second connector 50 is blocked by the top stop 103, while the first connector 40 can pass through smoothly.

[0054] Of course, in addition to the above methods, it is also feasible to set the first connector 40 as a female connector and the second connector 50 as a male connector, and to widen the male connector; or, it is also feasible to set the first connector 40 and the second connector 50 as magnetic connectors.

[0055] The seats provided in this application can be either front seats or rear seats.

[0056] Generally, the main body of a seat includes a backrest and a seat cushion.

[0057] In some other specific embodiments, the seat provided in this application is a front seat. The seat body includes a front seat cushion 20 and a front backrest 10 rotatably connected to the front seat cushion 20. After the headrest 30 is detached from the front backrest 10, the front backrest 10 can rotate to connect with the rear seat. With this configuration, after the headrest 30 is quickly detached, the front seat can connect with the rear seat to form an extended reclining area, giving the vehicle a campervan function.

[0058] Based on the aforementioned seat, this application also provides a vehicle that includes the aforementioned seat. Since the vehicle has the aforementioned seat, the beneficial effects brought by the seat are described above and will not be repeated here.
