[0002] With the increasing diversification of people's vehicle scenes, camping activities away from the hustle and bustle of the city and into nature have become a trend. People usually need to rest in the car when camping. In order to improve the user experience, the seats of the current car are designed to be able to be laid down so that people can lie down and rest. In addition, with the improvement of people's living standards, the requirement for the in-car sound is also getting higher and higher. In order to improve the effect of the sound, an independent sound is usually arranged in the headrest of the front seat.

[0003] When people go camping, there are usually many items placed in the trunk of the car, so it is not convenient to lay down the rear seat. Therefore, the front seat is laid down, and the laid-down front seat is docked with the rear seat to form a spacious and comfortable resting area. However, due to the limited space in the car, after the front seat is laid down, the headrest of the front seat will interfere with the rear seat, so that the front seat cannot be docked with the rear seat. Therefore, when the front seat is laid down again, the headrest of the front seat needs to be removed.

[0004] For the seat with an independent sound arranged in the headrest of the front seat, the wire harness of the sound in the headrest is usually connected together with the wire harness of the seat back, so that the headrest and the backrest are not convenient to disassemble. Therefore, the seat headrest with an independent sound arranged in the current stage is usually not detachable from the seat back, so that the front seat cannot be docked with the rear seat after being laid down, which affects the experience of people when resting.

[0068] In order for those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings.

[0069] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0070] With the increasing popularity of vehicles, the functions of vehicles are also increasingly diversified, and people are increasingly traveling, camping and other activities by car. People often need to rest in the car when traveling or camping. In order to meet the needs of people, the backrest of the seat of the current vehicle is usually designed to be able to be folded down.

[0071] Sometimes, people need to rest for a long time, in order to rest more comfortably, the backrest of the front seat is folded down and aligned with the rear seat to increase the rest area. However, due to the limited space in the vehicle, when the backrest of the front seat is folded down and aligned with the rear seat, the headrest of the front seat needs to be removed. For the front seat with independent audio in the headrest, since the audio harness and the backrest harness are connected together, the removal of the headrest is extremely inconvenient due to the influence of the audio harness and the backrest harness.

[0072] Based on this, the present application provides a vehicle, which comprises a seat, the seat can be a front seat or a rear seat, and the seat is taken as a front seat for illustration in the present application. The backrest of the seat can be folded down to facilitate people to lie down and rest. The vehicle can be an electric vehicle, a fuel vehicle, a hybrid vehicle, a gas vehicle, a solar vehicle, etc.

[0073] Figure 1 is a partial structure schematic view of a seat according to an exemplary embodiment, in order to facilitate the disassembly of the headrest and the backrest of the seat, as shown in Figure 1 the seat comprises a headrest 1, a backrest 2, an audio 3, a headrest harness 4 and a seat headrest mounting structure 5, Figure 2 is one of structure schematic views of the seat headrest mounting structure 5 according to an exemplary embodiment, as shown in Figure 2As shown in the figure, the seat further comprises a backrest wire harness 6, the backrest 2 is located below the headrest 1; the headrest 1 and the backrest 2 are connected through the seat headrest mounting structure 5, and the backrest wire harness 6 and the headrest wire harness 4 are also electrically connected through the seat headrest mounting structure 5.

[0074] As shown in the figure, Figure 2 the seat headrest mounting structure 5 comprises a support 51 and a connecting piece 52, Figure 3 is a schematic diagram of the structure of the seat headrest mounting structure 5 according to an exemplary embodiment, as shown in the figure, Figure 3 the seat headrest mounting structure 5 further comprises a first connector 53 and a second connector 54. The first end of the connecting piece 52 is connected with the headrest 1, the second connector 54 is connected to the second end of the connecting piece 52, and the second connector 54 is used to connect with the headrest wire harness 4.

[0075] Specifically, the connecting piece 52 can be a conduit, a wire slot, etc. One end of the headrest wire harness 4 is connected with the sound 3, and the other end of the headrest wire harness 4 passes through the inside of the connecting piece 52 and is connected with the second connector 54.

[0076] The support 51 is connected to the backrest 2, and the support 51 is used to set the first connector 53 and part of the backrest wire harness 6. Specifically, Figure 4 is a cross-sectional view of the first connector 53 and the second connector 54 at the second limit position according to an exemplary embodiment, as shown in the figure, Figure 4 the support 51 has a sliding channel 511 inside, the first connector 53 is arranged in the sliding channel 511, and the backrest wire harness 6 is connected with the first connector 53.

[0077] The second end of the connecting piece 52 and the second connector 54 can both extend into the sliding channel 511, and the second connector 54 can be detachably connected with the first connector 53. When connecting the headrest 1 with the backrest 2, the second end of the connecting piece 52 can be extended into the sliding channel 511. Since the second connector 54 is connected to the second end of the connecting piece 52, the second connector 54 will extend into the sliding channel 511 together with the second end of the connecting piece 52, and be connected with the first connector 53 located in the sliding channel 511, so that the connection between the connecting piece 52 and the support 51 is realized through the connection between the first connector 53 and the second connector 54, and the connection between the headrest 1 and the backrest 2 is realized. In addition, the connection between the first connector 53 and the second connector 54 also realizes the connection between the backrest wire harness 6 and the headrest wire harness 4.

[0078] Since the first connector 53 and the second connector 54 can be detachably connected, the first connector 53 and the second connector 54 can be conveniently connected and detached, thereby facilitating the connection and detachment of the support 51 and the connecting piece 52, and further facilitating the installation and detachment of the headrest 1 and the backrest 2. For the seat provided with the sound 3 in the headrest 1, the backrest wire harness 6 and the headrest wire harness 4 are also connected through the first connector 53 and the second connector 54. When the first connector 53 and the second connector 54 are convenient to connect and detach, the backrest wire harness 6 and the headrest wire harness 4 are also convenient to connect and detach.

[0079] Therefore, when it is necessary to lay down the front row of backrests 2 and align with the rear row of seats, the headrest 1 and the backrest 2 can be conveniently separated, and the backrest wire harness 6 and the headrest wire harness 4 can be conveniently separated, thereby avoiding the inconvenience of the headrest 1 and the backrest 2 caused by the connection of the headrest wire harness 4 and the backrest wire harness, and further facilitating the alignment of the front row of seats with the rear row of seats after being laid down, thereby improving the experience of people when resting.

[0080] The connection of the first connector 53 and the second connector 54 can realize the electrical connection of the backrest wire harness 6 and the headrest wire harness 4. Specifically, the seat further comprises a first terminal and a second terminal. One of the first terminal and the second terminal is arranged on the first connector 53 and electrically connected with the backrest wire harness 6. The other of the first terminal and the second terminal is arranged on the second connector 54 and electrically connected with the headrest wire harness 4. The first terminal and the second terminal can be inserted together.

[0081] When the first connector 53 and the second connector 54 are connected together, the first terminal and the second terminal can be inserted together, thereby realizing the electrical connection of the backrest wire harness 6 and the headrest wire harness 4 through the connection of the first terminal and the second terminal, so as to make the backrest wire harness 6 and the headrest wire harness 4 conductive.

[0082] In addition, in order to facilitate the adjustment of the height of the headrest 1, the first connector 53 can move along the extension direction of the sliding channel 511. Specifically, the first connector 53 can slide between a first limit position and a second limit position, and the first limit position is located on the side of the second limit position close to the headrest 1.

[0083] When the first connector 53 is located at the second limit position and the second connector 54 is separated from the first connector 53, the movement of the second connector 54 in the direction away from the headrest 1 can be connected with the first connector 53, that is, when the second connector 54 extends into the sliding channel 511, it will move from the first limit position to the second limit position and contact the first connector 53, until it moves to the second limit position, the first connector 53 will no longer move, and the second connector 54 will continue to press the first connector 53 to connect them.

[0084] It should be noted that, as shown in Figure 4 The limiting boss 512 is arranged at the second limit position to block the first connector 53 when the first connector 53 moves to the second limit position.

[0085] When the first connector 53 and the second connector 54 are clamped, the first connector 53 and the second connector 54 can be moved together in the sliding channel 511 by pulling the push head, so as to adjust the height of the headrest 1.

[0086] When the first connector 53 is at the first limit position and the second connector 54 is clamped with the first connector 53, moving the second connector 54 in the direction close to the headrest 1 can disengage the first connector 53, that is, when the first connector 53 and the second connector 54 move together in the direction close to the headrest 1 to the first limit position, the first connector 53 will no longer move, so that the first connector 53 continues to move in the direction close to the headrest 1, which can disengage the first connector 53 and the second connector 54, so as to remove the headrest 1.

[0087] It should be noted that, as shown in Figure 3 The push-away part 513 is arranged at the first limit position, and the push-away part 513 can block the first connector 53 moving to the first limit position.

[0088] The push-away part 513 can be a blocking boss arranged at the first limit position in the sliding channel 511, or can be formed by the structure of the support 51 itself.

[0089] Specifically, as shown in Figure 2 and Figure 3 The support 51 includes a fixed guide pipe 514, a clamping piece 515 and an adjusting guide pipe 516. The fixed guide pipe 514 is fixedly connected to the backrest 2. The fixed guide pipe 514 includes a first guide pipe 5141 and a second guide pipe 5142. The first guide pipe 5141 is welded to the framework of the backrest 2. The second guide pipe 5142 is located in the first guide pipe 5141, and both ends of the second guide pipe 5142 extend out of the first guide pipe 5141. Elastic abutting protrusions are arranged on the outer side walls of both ends of the second guide pipe 5142. The abutting protrusion at one end of the second guide pipe 5142 abuts against the end of the first guide pipe 5141, and the abutting protrusion at the other end of the second guide pipe 5142 abuts against the end of the first guide pipe 5141, so that the first guide pipe 5141 and the second guide pipe 5142 are clamped together.

[0090] Figure 5 is a cross-sectional structure schematic view of the support 51 according to an exemplary embodiment, as shown in Figure 5As shown, the fixed conduit 514 has a through channel 5143 in communication with the sliding channel 511, and the through channel 5143 can be a space inside the second conduit 5142. The end of the second conduit 5142 away from the headrest 1 can extend into the end of the adjusting conduit 516 close to the headrest 1 and be connected with the headrest 1, so that the through channel 5143 is in communication with the sliding channel 511, and at this time, the end of the second conduit 5142 away from the headrest 1 is located in the sliding channel 511, and the end of the second conduit 5142 away from the headrest 1 can form the push-away part 513.

[0091] In addition, Figure 6 is a cross-sectional view of the first connector 53 and the second connector 54 according to an exemplary embodiment, and is a cross-sectional view of the first connector 53 and the second connector 54 in the first limit position, as shown in Figure 2 、 Figure 3 and Figure 6 As shown, the end of the second conduit 5142 away from the headrest 1 is also provided with a clamping protrusion 51421 with elasticity, the end of the adjusting conduit 516 close to the headrest 1 is provided with a clamping opening 5161, the end of the adjusting conduit 516 close to the headrest 1 is sleeved on the end of the second conduit 5142 away from the headrest 1, and the clamping opening 5161 is clamped with the clamping protrusion 51421, so that the end of the adjusting conduit 516 close to the headrest 1 is clamped with the end of the fixed conduit 514 away from the headrest 1. The adjusting conduit 516 and the fixed conduit 514 are connected by clamping, which is convenient for installation and disassembly.

[0092] The sliding channel 511 is located in the adjusting conduit 516, and when the headrest 1 is installed on the backrest 2, the second end of the connecting piece 52 needs to pass through the sliding channel 511 and then extend into the sliding channel 511, so that the second connector 54 extends into the sliding channel 511 to clamp the second connector 54 with the first connector 53; the through channel 5143 and the sliding channel 511 can make the connecting piece 52 extend into the backrest 2 more, so that the connecting piece 52 is more firmly supported by the backrest 2, so that the headrest 1 is more firmly fixed.

[0093] The clamping piece 515 is arranged at the end of the fixed conduit 514 close to the headrest 1 and can be clamped with the connecting piece 52; specifically, the clamping piece 515 is fixedly connected to the end of the second conduit 5142 close to the headrest 1, and after the connecting piece 52 extends into the through channel 5143, the connecting piece 52 can be clamped with the clamping piece 515.

[0094] As shown in Figure 5As shown, the clamping piece 515 comprises a clamping guide post 5151, a clamping spring 5152 and a clamping switch 5153, the connecting piece 52 is provided with a plurality of clamping grooves, the clamping spring 5152 can drive the clamping guide post 5151 to extend into the clamping groove, so that the clamping piece 515 is clamped with the connecting piece 52, thereby fixing the connecting piece 52 with the fixed guide pipe 514, avoiding the shaking of the connecting piece 52 to affect the fixing of the headrest 1. The clamping switch 5153 can push the clamping guide post 5151 out of the clamping groove, so that the clamping piece 515 is disengaged from the connecting piece 52, so as to pull out the connecting piece 52 from the support piece 51, or make the second end of the connecting piece 52 slide in the support piece 51, so as to adjust the height of the headrest 1. After the height is adjusted to the right position, the connecting piece 52 is fixed by the clamping piece 515.

[0095] The clamping of the first connector 53 and the second connector 54 can also be clamped between the first limit position and the second limit position, or at the first limit position. At this time, a connecting rod can be provided on the first connector 53, and a long strip-shaped through hole is provided on the side wall of the adjusting guide pipe 516, so that the connecting rod extends out of the adjusting guide pipe 516. Thus, the position of the first connector 53 can be adjusted outside the adjusting guide pipe 516 by the connecting rod, and the first connector 53 is fixed by the connecting rod, so as to clamp the first connector 53 and the second connector 54 between the first limit position and the second limit position.

[0096] Moreover, such a setting can first fix the connecting piece 52 by the clamping piece 515, and then clamp the first connector 53 and the second connector 54, thereby improving the flexibility of clamping the first connector 53 and the second connector 54.

[0097] On this basis, in order to simplify the clamping mode of the first connector 53 and the second connector 54, the clamping of the first connector 53 and the second connector 54 can be realized by the clamping groove 55 and the clamping boss 56. For example, Figure 7 is a schematic view of the connection relationship between the first connector 53 and the second connector 54 according to an example embodiment, as shown in Figure 7 As shown, one of the first connector 53 and the second connector 54 is provided with a clamping plate 531, that is, the clamping plate 531 can be provided on the first connector 53, or can be provided on the second connector 54.

[0098] Figure 8 is a second cross-sectional view of the first connector 53 and the second connector 54 at the second limit position according to an example embodiment, as shown in Figure 8As shown, the seat headrest mounting structure 5 further comprises a clamping groove 55 and a clamping boss 56, one of which is arranged on the clamping plate 531, and the other of which is arranged on the other one of the first connector 53 and the second connector 54.

[0099] That is, if the clamping plate 531 is arranged on the first connector 53, the clamping groove 55 is arranged on the clamping plate 531, and the clamping boss 56 is arranged on the second connector 54, or the clamping groove 55 is arranged on the second connector 54, and the clamping boss 56 is arranged on the clamping plate 531; if the clamping plate 531 is arranged on the second connector 54, the clamping groove 55 is arranged on the clamping plate 531, and the clamping boss 56 is arranged on the first connector 53, or the clamping groove 55 is arranged on the first connector 53, and the clamping boss 56 is arranged on the clamping plate 531.

[0100] The clamping boss 56 is matched with the clamping groove 55 and can be clamped with the clamping groove 55, so that the clamping plate 531 is detachably clamped with the other one of the first connector 53 and the second connector 54, thereby enabling the first connector 53 and the second connector 54 to be detachably clamped.

[0101] The clamping boss 56 can be made elastic, or the clamping groove 55 can be made elastic, or the clamping plate 531 can be made elastic, so that the clamping boss 56 and the clamping groove 55 are clamped tightly by extrusion under the action of elasticity.

[0102] Here, the clamping plate 531 is arranged on the first connector 53 as an example, at this time, the second connector 54 comprises a clamping column 541, the clamping groove 55 is arranged on one of the clamping plate 531 and the clamping column 541, and the clamping boss 56 is arranged on the other one of the clamping plate 531 and the clamping column 541.

[0103] For example, the clamping boss 56 is arranged on the clamping plate 531, and the clamping groove 55 is arranged on the clamping column 541, the position of the clamping groove 55 can be on the side surface of the clamping column 541, or on the bottom surface of the clamping column 541, and the position of the clamping boss 56 corresponds to the position of the clamping groove 55. When the first connector 53 and the second connector 54 are clamped, only the clamping column 541 and the clamping plate 531 need to be in contact, and then extruded to make the clamping boss 56 enter the clamping groove 55; when the first connector 53 and the second connector 54 are separated, only the clamping column 541 and the clamping plate 531 need to be forced to move away from each other, so that the clamping boss 56 exits the clamping groove 55.

[0104] Specifically, in the first limit position, the first connector 53 is blocked by the limiting boss 512, that is, the clamping plate 531 is blocked, and when the second connector 54 is continuously pushed away from the headrest 1, the clamping column 541 will extrude the clamping plate 531, so that the clamping boss 56 is clamped into the clamping groove 55; in the second limit position, and when the first connector 53 and the second connector 54 are clamped, the clamping plate 531 will be blocked by the pushing part, and when the second connector 54 is continuously pulled towards the headrest 1, that is, the clamping column 541 is pulled, so that the clamping boss 56 is out of the clamping groove 55, so that the first connector 53 and the second connector 54 are separated.

[0105] Figure 9 It is a second cross-sectional view of the first connector 53 and the second connector 54 in the first limit position according to an exemplary embodiment, in order to effectively separate the clamping plate 531 and the clamping column 541, as shown in the figure, the push-away part 513 is arranged in the sliding channel 511, and is located on the side of the clamping plate 531 close to the headrest 1, that is, the push-away part 513 is located in the first limit position. Figure 9

[0106] Along the extension direction of the channel, the projection of the push-away part 513 at least partially coincides with the projection of the clamping plate 531, and does not coincide with the projection of the clamping column 541, that is, when the first connector 53 and the second connector 54 are in the clamped state, they are synchronously moved to the first limit position, and the push-away part 513 can only contact the clamping plate 531, so as to block the clamping plate 531, and the push-away part 513 cannot block the clamping column 541, so as to ensure that the clamping plate 531 and the clamping column 541 can be smoothly separated.

[0107] In some embodiments, as shown in Figure 4 and Figure 7 The first connector 53 further comprises a base 532, and the side of the base 532 close to the headrest 1 is provided with a positioning boss 5321, the clamping plate 531 and the positioning boss 5321 are arranged in a direction perpendicular to the extension direction of the sliding channel 511, and the clamping plate 531 is connected with the base 532.

[0108] The base 532 is used for supporting the positioning boss 5321 and the clamping plate 531, the positioning boss 5321 can be arranged at the center position of the base 532, and the clamping plate 531 is arranged at the edge position close to the base 532, or the positioning boss 5321 can be arranged at the edge position of the base 532, and the clamping plate 531 is arranged at the center position of the base 532.

[0109] ​In order to avoid the first connector 53 from being offset in the direction perpendicular to the extension direction of the sliding channel 511, the side wall of the base 532 is usually in contact with the inner side wall of the sliding channel 511 to limit the displacement of the base 532 in the direction perpendicular to the extension direction of the sliding channel 511 through the inner side wall of the sliding channel 511, thereby facilitating the butt joint of the second connector 54 and the second connector 54.

[0110] It should be noted that the base 532 can be circular, square, oval, polygonal, etc., and correspondingly, the sliding channel 511 can also be circular, square, oval, polygonal, etc.

[0111] It is taken as an example to illustrate that the positioning boss 5321 is arranged at the center position of the base 532, the clamping plate 531 is arranged at the position adjacent to the edge of the base 532, and the clamping boss 56 is arranged on the clamping plate 531, and the clamping groove 55 is arranged on the clamping column 541.

[0112] In order to further enable the first connector 53 and the second connector 54 to be more accurately butt jointed, a positioning groove is formed on the side of the clamping column 541 away from the headrest 1, the positioning groove is matched with the positioning boss 5321, and the positioning boss 5321 can extend into the positioning groove.

[0113] After the second connector 54 extends into the sliding channel 511, it will move from the first limit position to the second limit position and be in contact with the first connector 53, at this time, the positioning boss 5321 will enter the positioning groove, and through the connection of the positioning boss 5321 and the positioning groove, the positioning of the first connector 53 and the second connector 54 can be realized, so that the first connector 53 and the second connector 54 are accurately aligned, thereby facilitating the accurate clamping of the first connector 53 and the second connector 54.

[0114] After the first connector 53 and the second connector 54 are butt jointed, the side wall of the positioning groove and the side surface of the clamping column 541 are both located between the positioning boss 5321 and the clamping plate 531, so that the side surface of the clamping column 541 is in contact with the clamping plate 531 and is extruded with each other, thereby enabling the clamping boss 56 to be clamped into the clamping groove 55.

[0115] It should be noted that in the direction perpendicular to the extension direction of the sliding channel 511, the distance between the side surface of the clamping column 541 and the positioning boss 5321 is equal to the distance between the side wall of the positioning groove and the side surface of the clamping column 541.

[0116] The base 532 comprises a support base 5322 and a plurality of connecting plates 5323, the plurality of connecting plates 5323 are arranged at intervals around the extension direction of the sliding channel 511, the plurality of connecting plates 5323 are all located above the support base 5322 and connected with the support base 5322, and one clamping plate 531 is arranged between two adjacent connecting plates 5323, and the clamping plate 531 is connected with the two adjacent connecting plates 5323. The clamping plate 531 has one end close to the headrest 1 and one end away from the headrest 1, both of which are free ends. When the clamping plate 531 has elasticity, the clamping plate 531 can effectively elastically deform under the pressure of the clamping column 541, so that the clamping plate 531 can be effectively clamped with the clamping column 541.

[0117] On this basis, in order to make the clamping plate 531 more easily elastically deform, a plurality of notches 5311 extending along the extension direction of the sliding channel 511 are formed on the clamping plate 531, so as to reduce the resistance of the connecting plate 5323 to the clamping plate 531 when the clamping plate 531 elastically deforms, so that the clamping plate 531 can more easily deform.

[0118] In addition, the side surface of the base 532 is fitted with the side wall of the sliding channel 511, that is, the side surface of the clamping plate 531 close to the side wall of the sliding channel 511 and the side surface of the connecting plate 5323 close to the side wall of the sliding channel 511 are fitted with the side wall of the sliding channel 511. At this time, the clamping plate 531 will be limited by the side wall of the sliding channel 511 when it elastically deforms. To avoid this situation, as shown in Figure 2 An avoiding space 5111 is formed on the side wall of the sliding channel 511, the avoiding space 5111 corresponds to the clamping plate 531 one by one, and the avoiding space 5111 can reserve a movement space for the clamping plate 531 when the clamping plate 531 deforms, so that the clamping plate 531 can effectively elastically deform, so that the clamping plate 531 can be effectively clamped and separated with the clamping column 541.

[0119] It should be noted that the avoiding space 5111 can be a groove, a through hole, etc. In the embodiment, the avoiding space 5111 comprises an avoiding through hole 51112 and an avoiding groove 51111, the avoiding through hole 51112 is located at the first limit position, and is used for reserving a movement space for the clamping plate 531 when the first connector 53 and the second connector 54 are clamped at the first limit position; the avoiding groove 51111 is located at the second limit position, and is used for reserving a movement space for the clamping plate 531 when the first connector 53 and the second connector 54 are separated at the second limit position.

[0120] In some embodiments, in order to make the first connector 53 and the second connector 54 more easily separated at the first limit position, as shown in Figure 9As shown, a first guide slope 5131 can be arranged at the end of the push-away portion 513 away from the headrest 1, the end of the first guide slope 5131 close to the clamping plate 531 is away from the side wall of the sliding channel 511, and the end of the first guide slope 5131 away from the clamping plate 531 is close to the side wall of the sliding channel 511.

[0121] When the first connector 53 and the second connector 54 are clamped and moved to the first limit position, the end of the clamping plate 531 close to the headrest 1 is in contact with the first guide slope 5131, and under the guidance and blocking of the guide slope, the clamping plate 531 is away from the clamping column 541 in the direction close to the side wall of the sliding channel 511, so that the clamping boss 56 and the clamping groove 55 are separated, and then the first connector 53 and the second connector 54 are separated.

[0122] It should be noted that when the first guide slope 5131 is only arranged at the end of the push-away portion 513 away from the headrest 1, and the end of the clamping plate 531 close to the push-away portion 513 is not a slope, the end of the first guide slope 5131 close to the clamping plate 531 needs to be flush with or located on the side of the clamping plate 531 away from the side wall of the sliding channel 511, so that the clamping plate 531 can effectively contact the first guide slope 5131.

[0123] A second guide slope 5312 can also be arranged at the end of the clamping plate 531 close to the push-away portion 513, the end of the second guide slope 5312 close to the push-away portion 513 is close to the side wall of the sliding channel 511, and the end of the second guide slope 5312 away from the push-away portion 513 is away from the side wall of the sliding channel 511.

[0124] When the first connector 53 and the second connector 54 are clamped and moved to the first limit position, the end of the push-away portion 513 away from the headrest 1 is in contact with the second guide slope 5312, and under the guidance and blocking of the guide slope, the clamping plate 531 is away from the clamping column 541 in the direction close to the side wall of the sliding channel 511, so that the clamping boss 56 and the clamping groove 55 are separated, and then the first connector 53 and the second connector 54 are separated.

[0125] It should be noted that when the second guide slope 5312 is only arranged at the end of the clamping plate 531 close to the push-away portion 513, and the end of the push-away portion 513 close to the clamping plate 531 is not a slope, the end of the second guide slope 5312 close to the push-away portion 513 needs to be flush with or located on the side of the push-away portion 513 close to the side wall of the sliding channel 511, so that the push-away portion 513 can effectively contact the second guide slope 5312.

[0126] The first guide slope 5131 and the second guide slope 5312 can be arranged simultaneously, and in this case, the projection of the first guide slope 5131 and the projection of the second guide slope 5312 partially overlap in the extension direction of the sliding channel 511, so that the first guide slope 5131 and the second guide slope 5312 can effectively contact each other in the first limit position, thereby effectively separating the clamping plate 531 from the clamping post 541.

[0127] In some embodiments, in order to avoid the first connector 53 rotating or sliding in the sliding channel 511 and affecting the clamping of the first connector 53 and the second connector 54, Figure 10 is a schematic top view of the seat headrest mounting structure 5 according to an exemplary embodiment, as Figure 10 As shown, the seat headrest mounting structure 5 further comprises at least one guide groove 57 and at least one guide boss 58, the guide groove 57 and the guide boss 58 both extend along the extension direction of the sliding channel 511, the guide groove 57 is arranged on one of the side surface of the clamping plate 531 close to the side wall of the sliding channel 511 and the side wall of the sliding channel 511; the guide boss 58 is arranged on the other one of the side surface of the clamping plate 531 close to the side wall of the sliding channel 511 and the side wall of the sliding channel 511, one guide boss 58 corresponds to one guide groove 57 and is located in one guide groove 57.

[0128] That is, if the guide groove 57 is arranged on the side surface of the clamping plate 531 close to the side wall of the sliding channel 511, the guide boss 58 is arranged on the side wall of the sliding channel 511; if the guide groove 57 is arranged on the side wall of the sliding channel 511, the guide boss 58 is arranged on the side surface of the clamping plate 531 close to the side wall of the sliding channel 511.

[0129] By arranging the guide boss 58 in the guide groove 57, the first connector 53 can be limited by the guide boss 58 and the guide groove 57 when sliding in the sliding channel 511, so that the first connector 53 will not rotate or shake, thereby making the movement of the first connector 53 more stable, and the second connector 54 can be more accurately connected with the first connector 53, so as to quickly clamp the first connector 53 and the second connector 54.

[0130] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
