[0080] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0081] This application proposes a seat structure. Figures 1 to 12 These are some embodiments of the present application.

[0082] See also Figures 1 to 3 In some embodiments of the present application, the seat structure includes a seat body 1 and an adjustment component 4, the seat body 1 includes a first body portion 11 and a second body portion 12, the adjustment component 4 is connected to the seat body 1, and the adjustment component 4 is used to adjust the seat body 1 so that the seat body 1 switches between a first state and a second state; that is, the seat body 1 can be adjusted, when the seat body 1 is in one working state, the second body portion 12 on the seat body 1 can be used for passengers to sit on, and when the seat body 1 is in another working state, the first body portion 11 on the seat body 1 can be used for people to sit on.

[0083] See also Figure 4 The seat body 1 has a first state and a second state. When the seat body 1 is in the first state, the first body part 11 is a seat and the second body part 12 is a backrest; when the seat body 1 is in the second state, the first body part 11 is a backrest and the second body part 12 is a seat.

[0084] It should be noted that the application scenario of the seat structure proposed in this application is not limited. The seat structure can be installed in indoor environments, such as offices, conference halls, etc.; it can also be installed in outdoor environments, such as entertainment facilities with seats, etc.; it can also be installed in vehicles.

[0085] In some embodiments of the present application, the seat structure is installed on a vehicle for description. That is, in some embodiments of the present application, when the second body portion 12 of the seat structure is for a person to sit on, the person sitting on the second body portion 12 faces the front of the vehicle; when the first body portion 11 of the seat structure is for a person to sit on, the person sitting on the first body portion 11 faces the rear of the vehicle; that is, by adjusting the seat body 1 through the adjustment component 4, the direction of the person sitting on the seat body 1 can be adjusted.

[0086] In the technical solution of the present application, the seat body 1 is adjusted by providing an adjustment component 4 so that both the first body part 11 and the second body part 12 on the seat body 1 can be used for passengers to sit on; that is, in this embodiment, the functions of the first body part 11 and the second body part 12 of the seat body 1 can be switched to meet the diverse needs of the passengers.

[0087] In some embodiments of the present application, the adjustment component 4 is a flip component 40, which is connected to the seat body 1. The flip component 40 is used to flip the seat body 1 so that the seat body 1 can switch between the first state and the second state; that is, the seat body 1 can be flipped along with the flip component 40, so that the functions of the first body part 11 and the second body part 12 of the seat body 1 can be switched.

[0088] The structure of the seat body 1 is adjusted by flipping, so that the avoidance space required for adjusting the seat structure is smaller; that is, when the seat structure is assembled on the vehicle, the avoidance space required for adjusting the seat structure is smaller.

[0089] It can be understood that since the seat body 1 is adjusted by flipping the flip assembly 40, when the function of the first body part 11 or the second body part 12 of the seat body 1 is switched, the passengers sit on the first body part 11 and the second body part 12 respectively, that is, when the passengers sit on the first body part 11 and the second body part 12, the orientation of the passengers in the vehicle is also different.

[0090] In some embodiments of the present application, the flip assembly 40 includes a connecting portion 401, which is connected to the seat body 1 and is configured to drive the seat body 1 to flip; that is, in this embodiment, the seat body 1 achieves a flipping function by connecting to the connecting portion 401.

[0091] In some embodiments of the present application, the flipping assembly 40 also includes a first torsion spring 402, which is connected to the connecting part 401 so as to undergo elastic deformation when the connecting part 401 drives the seat body 1 to flip; that is, in this embodiment, the first torsion spring 402 will undergo elastic deformation when the seat body 1 flips, thereby utilizing its own elastic force to assist the seat body 1 in resetting when the seat body 1 is reset.

[0092] For example, in one embodiment, the first body 11 of the seat body 1 is for people to sit on. When the seat body 1 is flipped to the second body 12 for people to sit on, the first torsion spring 402 undergoes elastic deformation, thereby using its own elastic force to assist the seat body 1 in flipping when the seat body 1 is flipped again to the first body 11 for people to sit on.

[0093] In some embodiments of the present application, the seat structure also includes a fixing component 30, and a flipping component 40 is movably arranged on the fixing component 30, and the fixing component 30 is configured to support the flipping component 40; in this embodiment, the seat structure can be fixed in a position to be fixed by the fixing component 30, so that people can use it.

[0094] In some embodiments of the present application, the seat structure can be fixed to the floor of the vehicle through the fixing assembly 30 so as to allow passengers to sit on it.

[0095] In some embodiments of the present application, the fixing assembly 30 includes a fixing portion 31, the fixing portion 31 includes a connecting end 310, and the flipping assembly 40 is configured to be rotatably mounted on the connecting end 310 of the fixing portion 31; wherein the seat body 1 can be rotatably mounted on the connecting end 310 on the fixing portion 31 through the flipping assembly 40, so that the seat body 1 can rotate around the fixing portion 31.

[0096] In some embodiments of the present application, the flipping assembly 40 includes a first torsion spring 402, which is installed on the connecting end 310 and undergoes elastic deformation when the seat body 1 is flipped. That is, in this embodiment, the first torsion spring 402 undergoes elastic deformation when the seat body 1 is flipped, thereby utilizing its own elastic force to assist the seat body 1 in resetting when the seat body 1 is reset; for example, in one embodiment, the first body 11 of the seat body 1 is for people to sit on, and when the seat body 1 is flipped to the second body 12 for people to sit on, the first torsion spring 402 undergoes elastic deformation, thereby utilizing its own elastic force to assist the seat body 1 in flipping when the seat body 1 is flipped again to the first body 11 for people to sit on.

[0097] In some embodiments of the present application, the flipping assembly 40 includes a first torsion spring 402 and a connecting portion 401, the connecting portion 401 is rotatably mounted on the connecting end 310 of the fixing portion 31, one end of the first torsion spring 402 is connected to the connecting portion 401, and the other end is connected to the connecting end 310 of the fixing portion 31; that is, in this embodiment, when the seat body 1 flips around the fixing portion 31, the first torsion spring 402 will undergo elastic deformation, thereby utilizing its own elastic force to assist the seat body 1 in resetting when the seat body 1 is reset.

[0098] In some embodiments of the present application, the fixing component 30 includes a fixing portion 31, the fixing portion 31 includes a connecting end 310, the connecting end 310 is located on one side of the fixing portion 31 in the first direction, and the flipping component 40 is configured to be rotatably mounted on the connecting end 310; that is, in this embodiment, the flipping component 40 is opposite to the fixing portion 31 in the fixing component 30 in the first direction, so that the fixing portion 31 can support the flipping component 40 while avoiding the structural setting of the fixing portion 31 from interfering with the movement of the flipping component 40.

[0099] In some embodiments of the present application, the connecting portion 401 is located at one side of the fixing portion 31 in the first direction to avoid interference between the connecting portion 401 and the fixing portion 31 during rotation.

[0100] In some embodiments of the present application, the flip assembly 40 includes a connecting portion 401, which is rotatably mounted on the fixing portion 31 and connected to the seat body 1; wherein the seat body 1 can be rotatably mounted on the fixing portion 31 through the connecting portion 401, so that the seat body 1 can rotate around the fixing portion 31.

[0101] In some embodiments of the present application, the rotation angle of the seat body 1 is 90°.

[0102] In some embodiments of the present application, the fixing assembly also includes a limiting portion 32; wherein the limiting portion 32 is connected to the fixing portion 31 and is configured to limit the seat body 1; that is, in this embodiment, the limiting portion 32 can limit the movement of the seat body 1 to improve the stability of the seat body 1 when the seat body 1 is for people to sit on.

[0103] It is understandable that there is no limitation on the connection method between the limiting portion 32 and the fixing portion 31 ; the fixing portion 31 and the limiting portion 32 may be directly connected or connected via other components.

[0104] In some embodiments of the present application, the limiting portion 32 includes two limiting sub-portions 321, and the two limiting sub-portions 321 are arranged at intervals along the first direction to limit the seat body 1 in the first direction; that is, in this embodiment, the two limiting sub-portions 321 can limit the movement of the seat body 1 in the first direction to improve the stability of the seat body 1 when the seat body 1 is for people to sit on.

[0105] Among them, there is a certain gap between the two limiting sub-portions 321 in the first direction. A part of the seat body 1 may be located between the two limiting sub-portions 321, or a component connected to the seat body 1 may be located between the two limiting sub-portions 321, so as to realize the limiting sub-portion 321 limiting the seat body 1 in the first direction.

[0106] See also Figure 3 and Figure 5 In some embodiments of the present application, the seat structure also includes a slide rail assembly 13, a fixed assembly 30 is slidably arranged on the slide rail assembly 13, and the slide rail assembly 13 is installed on the floor of the vehicle; that is, in this embodiment, since the seat body 1 is installed on the fixed assembly 30, the fixed assembly 30 can move on the slide rail assembly 13, that is, the seat body 1 can also move along the slide rail assembly 13 to adjust the position of the seat body 1 in the vehicle, thereby improving the flexibility of the seat structure.

[0107] It should be noted that, since the seat body 1 in the present application can be flipped by the flip assembly 40 and can also move along the extension direction of the slide rail assembly 13, please refer to Figure 4 In some embodiments of the present application, the second main body portion 12 is used for passengers to sit on. When the second main body portion 12 needs to be switched to the first main body portion 11 for passengers to sit on, the seat body 1 is flipped through the flip assembly 40. At this time, the relative position of the seat body 1 on the vehicle changes. The seat body 1 can be operated to slide on the slide rail assembly 13, and then the seat body 1 can be restored to its initial position before flipping; that is, the flipping function of the seat body 1 can be realized without changing the sitting position of the passengers.

[0108] Among them, the seat structure in the embodiment of the present application can be applied to vehicles with multiple rows of seats, such as vehicles with three rows of seats. After the seats in the middle row are flipped and slid, they will not occupy the riding space of passengers in the other two rows of seats, thereby improving the diverse needs of passengers while ensuring the comfort of passengers.

[0109] In some embodiments of the present application, the fixing assembly 30 includes a fixing portion 31 and a limiting portion 32, that is, the fixing portion 31 and the limiting portion 32 can both move along the slide rail 14; wherein, the fixing portion 31 and the limiting portion 32 can be directly slidably installed on the slide rail 14, or can be slidably installed on the slide rail 14 through other components, which is not limited here.

[0120] In some embodiments of the present application, the connecting component 8 includes a connecting member 81 and a matching member 82, the connecting member 81 is arranged on the seat body 1 and / or the flipping component 40; the matching member 82 is arranged on the fixing portion 31; wherein, the connecting member 81 and the matching member 82 cooperate with each other to limit the rotation of the seat body 1; that is, in this embodiment, when the second body portion 12 or the first body portion 11 is for passengers to sit on, the connecting member 81 and the matching member 82 cooperate with each other to limit the flipping of the seat body 1, thereby ensuring the safety of the passengers.

[0121] There is no limitation on the connection relationship between the connecting member 81 and the matching member 82, which may be a snap connection or a screw connection.

[0122] Among them, since the seat body 1 and the flip assembly 40 are connected to each other, the connection between the connecting member 81 and at least one of the seat body 1 and the flip assembly 40 can ensure that the assembly of the connecting member 81 and the matching member 82 can limit the flipping of the seat body 1.

[0123] See also Figure 6 and Figure 7 In some embodiments of the present application, one of the connecting member 81 and the mating member 82 includes a first mating portion 811, and the other includes a second mating portion 821, and the first mating portion 811 and the second mating portion 821 are interlocked; that is, in this embodiment, the first mating portion 811 and the second mating portion 821 are interlocked to limit the flipping of the seat body 1, thereby ensuring the safety of the passengers.

[0124] In some embodiments of the present application, one of the first matching portion 811 and the second matching portion 821 includes a hook, and the other includes a hook rod, and the hook and the hook rod are interlocked.

[0125] See also Figure 4 and Figure 5 In some embodiments of the present application, the first mating portion 811 includes a hook, and the second mating portion 821 includes a hook rod.

[0126] In some embodiments of the present application, the connecting member 81 includes an abutment portion 813, which is arranged on the seat body 1 and / or the flip assembly 40 and abuts against the fixing assembly 30 to limit the first matching portion 811 or the second matching portion 821 arranged on the connecting member 81 from approaching the fixing assembly 30; that is, in this embodiment, the abutment portion 813 is provided to avoid the seat body 1 being pressed down by its own gravity or the passenger sitting on the seat body 1, thereby preventing the first matching portion 811 or the second matching portion 821 from abutting against the fixing assembly 30 and causing damage.

[0127] In some embodiments of the present application, the connecting member 81 also includes a main body 812 and an abutting portion 813, the main body 812 is connected to the seat body 1 and / or the flip assembly 40, and the first matching portion 811 or the second matching portion 821 is arranged on the main body 812; the abutting portion 813 is arranged on the main body 812 and abuts against the fixing assembly 30 to limit the first matching portion 811 or the second matching portion 821 arranged on the main body 812 from approaching the fixing assembly 30; that is, in this embodiment, the abutting portion 813 is arranged to avoid the main body 812 being pressed down due to the gravity of the seat body 1 itself or the passengers sitting on the seat body 1, thereby causing the first matching portion 811 or the second matching portion 821 installed on the main body 812 to abut against the fixing assembly 30 and cause damage.

[0128] In some embodiments of the present application, a first matching portion 811 is disposed on the main body portion 812 , and a second matching portion 821 is disposed on the limiting portion 32 .

[0129] In some embodiments of the present application, the abutment portion 813 can limit the first matching portion 811 from approaching the fixing assembly 30 in the direction of gravity, that is, limit the hook from approaching the fixing assembly 30 to avoid damage to the hook.

[0130] In some embodiments of the present application, the limiting portion 32 includes two limiting sub-portions 321, and the two limiting sub-portions 321 are spaced apart in the first direction; wherein, at least a portion of the first matching portion 811 and at least a portion of the second matching portion 821 are located between the two limiting sub-portions 321; that is, the two limiting sub-portions 321 can protect and limit the first matching portion 811 and the second matching portion 821 in the first direction, and at the same time limit the movement of the main body 812 after the first matching portion 811 and the second matching portion 821 are buckled with each other, so as to limit the movement of the seat body 1.

[0131] It is understandable that, since the first matching portion 811 is connected to the main body portion 812 , the movement restriction of the first matching portion 811 by the two limiting portions 32 can also restrict the movement of the main body portion 812 .

[0132] In some embodiments of the present application, at least a portion of the main body 812 is also located between the two limiting portions 32 .

[0133] In addition, the provision of the two limiting portions 32 can also prevent the body of the passenger from extending into between the first matching portion 811 and the second matching portion 821 and causing injury.

[0134] In some embodiments of the present application, the seat structure also includes an operating member 10, which is disposed on the seat body 1 and is configured to release the flipping restriction of the seat body 1 by the connecting component 8; that is, in this embodiment, the occupant can operate the operating member 10 to release the flipping restriction of the seat body 1 by the connecting component 8, thereby enabling the occupant to flip the seat body 1.

[0135] In some embodiments of the present application, the operating member 10 and the first matching portion 811 are both arranged on the seat body 1, and the operating member 10 is connected to the first matching portion 811 to drive the first matching portion 811 to separate from the second matching portion 821; in this embodiment, the setting of the operating member 10 facilitates the passenger to unlock the seat body 1 to flip the seat body 1.

[0136] It can be understood that since the operating member 10 is connected to the first matching portion 811, when the connecting member 81 includes the first matching portion 811, the operating member 10 is arranged on the seat body 1, that is, the operating member 10 can be arranged on the first body portion 11 or the second body portion 12; when the matching member 82 includes the first matching portion 811, the operating member 10 is arranged on the fixed portion 31; in addition, when the connecting member 81 includes the first matching portion 811, the operating member 10 can also be arranged on the connecting portion 401.

[0137] In some embodiments of the present application, the first matching portion 811 is movably mounted on the main body 812 , and the operating member 10 is transmission-connected to the first matching portion 811 , so as to control the movement of the first matching portion 811 .

[0138] In some embodiments of the present application, two connecting members 81 are provided and are respectively provided on the first main body portion 11 and the second main body portion 12, and two matching members 82 are also provided on the fixing portion 31, so as to respectively connect the connecting members 81 provided on the first main body portion 11 or the second main body portion 12 when the first main body portion 11 or the second main body portion 12 is provided for people to sit on; in addition, two operating members 10 are provided and are respectively provided on the first main body portion 11 and the second main body portion 12, so that the passengers can simultaneously flip the seat body 1 after driving the first matching member 811 and the second matching member 821 to separate.

[0139] In some embodiments of the present application, the connecting member 81 is rotatably mounted on the seat body 1 or the flip assembly 40. With such an arrangement, when the passenger sits on the seat body 1, the connecting member 81 can be rotated out from the seat body 1 or the flip assembly 40 to cooperate with the matching member 82 to fix the seat body 1, so as to improve the aesthetics of the seat structure.

[0140] In some embodiments of the present application, two connecting members 81 are provided, and are respectively rotatably installed on the second body portion 12 or the first body portion 11 of the seat body 1. When the passengers sit on the second body portion 12 or the first body portion 11, the connecting members 81 can be rotated out from the second body portion 12 or the first body portion 11 to cooperate with the corresponding matching members 82 to fix the seat body 1; at the same time, when the passengers sit on the second body portion 12 or the first body portion 11, the connecting members 81 located on the first body portion 11 or the second body portion 12 can be rotatably stored in the first body portion 11 or the second body portion 12 to improve the aesthetics of the seat structure.

[0141] In some embodiments of the present application, a first groove is provided on the second main body portion 12, and a connecting member 81 located on the second main body portion 12 is rotatably provided in the first groove, and a first cover plate is movably provided at the opening of the first groove; when the passenger sits on the second main body portion 12, the connecting member 81 pushes open the first cover plate and connects with the matching member 82, and when the passenger sits on the first main body portion 11, the connecting member 81 is rotated and stored in the first groove and the first cover plate covers the opening of the first groove.

[0142] In some embodiments of the present application, a second groove is provided on the first main body portion 11, and a connecting member 81 located on the first main body portion 11 is rotatably provided in the second groove, and a second cover plate is movably provided at the opening of the second groove; when the passenger sits on the first main body portion 11, the connecting member 81 pushes open the second cover plate and connects with the matching member 82, and when the passenger sits on the second main body portion 12, the connecting member 81 is rotated and stored in the second groove and the second cover plate covers the opening of the second groove.

[0143] See also Figure 7 In some embodiments of the present application, a third torsion spring 16 is arranged between the connecting member 81 and the second body portion 12 and the first body portion 11, and the seat structure also includes a winding structure, which is respectively connected to the two connecting members 81 located on the first body portion 11 and the second body portion 12 in a transmission manner. For example, in one embodiment, the seat body 1 is flipped so that the second body portion 12 where the passenger sits is switched to the first body portion 11. At this time, the winding structure releases the restriction on the connecting member 81 located on the first body portion 11, and the connecting member 81 located on the first body portion 11 pushes open the second cover plate and rotates out of the second groove to connect with the matching member 82; at the same time, the winding structure tightens the connecting member 81 located on the second body portion 12, so that the connecting member 81 located on the second body portion 12 rotates into the first groove, and the third torsion spring 16 between the connecting member 81 located on the second body portion 12 and the second body portion 12 is compressed.

[0144] It can be understood that when the seat body 1 is flipped so that the first body part 11 on which the occupant sits is switched to the second body part 12, the third torsion spring 16 compressed between the connecting member 81 and the second body part 12 drives the connecting member 81 on the second body part 12 to rotate out of the first groove and connect with the mating member 82, and the winding structure releases the restriction on the connecting member 81 on the second body part 12.

[0145] Such a configuration makes it unnecessary for the passengers to manually rotate out or store the two connecting members 81 on the first body portion 11 and the second body portion 12 , so that the passengers can easily perform the flipping operation on the seat body 1 .

[0146] In some embodiments of the present application, the flip assembly 40 also includes a first torsion spring 402, one end of the first torsion spring 402 is connected to the connecting part 401, and the other end is connected to the fixing part 31; wherein, the second body part 12 of the seat body 1 is for passengers to sit on, which is the initial state of the seat body 1. When the seat body 1 is flipped so that the first body part 11 is for passengers to sit on, the rotation of the seat body 1 will compress the first torsion spring 402. When the seat body 1 is reset to the second body part 12 for passengers to sit on, the first torsion spring 402 can be released to provide power for the reset of the seat body 1, so as to facilitate the passengers to reset the seat body 1.

[0148] It is understandable that, since the seat body 1 has a certain length in the first direction, a support member 9 is provided between the two flip assemblies 40 to jointly support the seat body 1 , thereby improving the stability of the seat body 1 when the seat body 1 is provided for sitting.

[0149] In some embodiments of the present application, the support member 9 is fixedly connected to the connecting parts 401 in the two flip assemblies 40; in this embodiment, the seat body 1 is jointly supported by the two connecting parts 401 and the support member 9 to improve the stability of the seat body 1 when the seat body 1 is for people to sit on.

[0150] In some embodiments of the present application, the support member 9 is a frame beam of the seat, and the two spaced-apart connection portions are respectively fixedly connected to the support member 9 to form a frame of the seat and support the seat body 1 .

[0151] In some embodiments of the present application, the seat structure also includes two fixed components 30 and two slide rail components 13, the two fixed components 30 are arranged at intervals along the first direction X, and the two flip components 40 are respectively movably arranged on the two fixed components 30; the two slide rail components 13 are arranged at intervals along the first direction X, and the two fixed components 30 are respectively slidably arranged on the two slide rail components 13; in this embodiment, the two flip components 40 of the seat structure are respectively installed on the two fixed components 30, that is, the two flip components 40 and the support members 9 connecting the two flip components 40 can be supported by the two fixed components 30 to improve the stability of the seat body 1 when flipping and providing passengers with a seat; in addition, the two fixed components 30 are respectively slidably arranged on the two slide rail components 13, so that the seat body 1 can move along the slide rail components 13, while also ensuring the stability of the seat body 1 when sliding.

[0152] In some embodiments of the present application, the seat structure also includes a headrest 3, which is detachably arranged on the first body part 11 or the second body part 12; when the second body part 12 on the seat body 1 is for people to sit on, the headrest 3 can be installed on the first body part 11 of the seat body 1, so that the headrest 3 can support the head and neck of the occupant; when the first body part 11 on the seat body 1 is for people to sit on, the headrest 3 can also be installed on the second body part 12 of the seat body 1, so that the headrest 3 can support the head and neck of the occupant.

[0153] In some embodiments of the present application, a mounting position 2 is provided on both the first main body portion 11 and the second main body portion 12; the headrest 3 can be detachably provided on any mounting position 2 located on the first main body portion 11 and the second main body portion 12; that is, the headrest 3 can be installed on the mounting positions 2 on the first main body portion 11 and the second main body portion 12 respectively according to different usage states of the seat body 1.

[0154] In some embodiments of the present application, at least one mounting position is provided on the first main body portion 11 and the second main body portion 12, and at least one headrest 3 is detachably provided on one mounting position 2; that is, in this embodiment, the number of mounting positions 2 on the first main body portion 11 and the second main body portion 12 and the headrest 3 on the mounting positions 2 are not limited and can be designed according to actual production requirements.

[0155] It can be understood that since the seat structure of the present application requires a small amount of avoidance space in the vehicle when adjusting, the seat structure of the present application can be applied to various types of vehicles, such as vehicles with rows of seats or small and medium-sized vehicles, to meet the different usage needs of passengers.

[0156] See also Figures 8 to 10In some embodiments of the present application, the headrest 3 includes a headrest body 301 and a connecting rod 302, the headrest body 301 is connected to the connecting rod 302, and the connecting rod 302 is movably arranged on the installation position 2; wherein, by movably adjusting the position of the connecting rod 302 on the installation position 2, the distance between the headrest body 301 and the second body part 12 or the first body part 11 is adjusted, that is, the headrest body 301 can adjust its height in the vehicle according to the usage needs of the passengers.

[0157] In some embodiments of the present application, the seat structure also includes a limit assembly 5, which is used to limit the activity state of the connecting rod 302; that is, in this embodiment, the limit assembly 5 can limit the activity of the connecting rod 302 at the installation position 2, and the limit assembly 5 can also release the activity restriction on the connecting rod 302 at the installation position 2.

[0158] In some embodiments of the present application, the limiting assembly 5 includes a limiting member 51, which is movably arranged on the installation position 2, and the limiting member 51 has a first position and a second position; when the limiting member 51 is in the first position, the limiting member 51 abuts against the connecting rod 302, and the connecting rod 302 is fixed on the installation position 2; when the limiting member 51 is in the second position, the limiting member 51 is separated from the connecting rod 302, and the connecting rod 302 is movably arranged on the installation position 2; in this embodiment, when it is necessary to adjust the position of the headrest body 301, the passenger controls the limiting member 51 to be in the second position so that the connecting rod 302 can move freely on the installation position 2, thereby adjusting the height of the headrest body 301 in the vehicle; after the passenger has adjusted the height position of the headrest body 301 in the vehicle, the passenger can control the limiting member 51 to be in the first position, at which time the connecting rod 302 is limited on the installation position 2 of the first body part 11 or the second body part 12 to prevent the headrest 3 from moving during use.

[0159] In some embodiments of the present application, a toothed structure or a tooth groove is provided on the connecting rod 302 , and the limiting member 51 cooperates with the toothed structure or the tooth groove to limit the movement of the connecting rod 302 .

[0160] It is understandable that in some embodiments of the present application, a limiting member 51 is provided on both the first body portion 11 and the second body portion 12 so that when the headrest 3 is installed on the first body portion 11 and the second body portion 12 , the height of the headrest 3 in the vehicle can be adjusted.

[0161] In some embodiments of the present application, the limit assembly 5 also includes a shell 52, which is arranged on the installation position 2, and the limit member 51 is movably installed in the shell 52; wherein the shell 52 is installed on both the first main body portion 11 and the second main body portion 12, and the shell 52 is made of a hard material, so that the limit member 51 can move in the shell 52.

[0162] In some embodiments of the present application, one end of the connecting rod 302 away from the headrest body 301 extends into the shell 52 and can move relative to the shell 52 to adjust the distance between the headrest body 301 and the shell 52; that is, in this embodiment, the height of the headrest body 301 in the vehicle is adjusted by adjusting the size of the connecting rod 302 extending into the shell 52.

[0163] The connecting rod 302 may be composed of one or more rod segments, and the rod segments may extend into the housing 52. Fig. 9 In some embodiments of the present application, the connecting rod 302 is composed of two rod segments, and the two rod segments are both connected to the headrest body 301 to improve the stability of the headrest body 301 when it is set on the installation position 2.

[0164] In some embodiments of the present application, two rod sections of the connecting rod 302 are connected to each other.

[0165] In some embodiments of the present application, scale marks are provided on the connecting rod 302 , and passengers can adjust the height of the connecting rod 302 in the vehicle according to the scale marks on the connecting rod 302 .

[0166] See also Figures 9 to 11 In some embodiments of the present application, the limiting assembly 5 further includes a driving member 50, which drives the limiting member 51 to switch between the first position and the second position; that is, the movement of the limiting member 51 is controlled by the driving member 50 so that the limiting member 51 abuts against or separates from the connecting rod 302, thereby being able to adjust the height of the headrest 3 in the vehicle.

[0167] In some embodiments of the present application, the driving member 50 includes a first driving member 501, which is disposed on the shell 52 and is used to drive the limiting member 51 to switch between the first position and the second position; that is, the movement of the limiting member 51 is controlled by the first driving member 501 so that the limiting member 51 abuts against or separates from the connecting rod 302, thereby being able to adjust the height of the headrest 3 in the vehicle.

[0168] See also Figures 8 to 10In some embodiments of the present application, the first driving member 501 includes an adjusting portion 5011, which is movably mounted outside the housing 52, and a portion of the limiting member 51 extends from the housing 52 and is located on the movement trajectory of the adjusting portion 5011; the adjusting portion 5011 has a third position, and when the adjusting portion 5011 is in the third position, the adjusting portion 5011 abuts against the limiting member 51 and drives the limiting member 51 to separate from the connecting rod 302; wherein, a portion of the housing 52 is exposed from the first body portion 11 or the second body portion 12, and the adjusting portion 5011 is movably mounted at the exposed position of the housing 52, so that the passengers can directly operate the adjusting portion 5011. That is, the passengers can move the adjusting portion 5011 until the adjusting portion 5011 is in the third position, so that the limiting member 51 cancels the activity restriction on the connecting rod 302 and adjusts the length of the connecting rod 302 inserted into the housing 52.

[0169] In some embodiments of the present application, the adjustment portion 5011 is slidably mounted on the housing 52, so that the movement of the adjustment portion 5011 is relatively simple, which is convenient for passengers to operate.

[0170] In some embodiments of the present application, the adjustment portion 5011 has a fourth position. When the adjustment portion 5011 is in the fourth position, the adjustment portion 5011 abuts against the limiting member 51 and drives the limiting member 51 to abut against the connecting rod 302; in this embodiment, the passenger can adjust the adjustment portion 5011 until the adjustment portion 5011 is in the fourth position so that the limiting member 51 can move to the first position, thereby limiting the connecting rod 302.

[0171] In some embodiments of the present application, when the adjusting portion 5011 is in the fourth position, it can also limit the connecting rod 302 together with the limiting member 51 to improve the reliability of the relative fixation between the headrest 3 and the shell 52.

[0172] In some embodiments of the present application, the first driving member 501 also includes an elastic member 5012, which connects the shell 52 and the adjusting portion 5011 to drive the adjusting portion 5011 to move from the third position to the fourth position; in this embodiment, the adjusting portion 5011 is in the fourth position due to the elastic force of the elastic member 5012 in the initial state. At this time, the adjusting portion 5011 will not drive the limiting member 51 to move, and the limiting member 51 can limit the connecting rod 302. When the height of the headrest 3 in the vehicle needs to be adjusted, the passenger needs to drive the adjusting portion 5011 to move, and at the same time drive the limiting member 51 to separate from the connecting rod 302, so that the connecting rod 302 can move freely relative to the shell 52.

[0173] It can be understood that when the elastic member 5012 drives the adjusting portion 5011 to move from the third position to the fourth position, the adjusting portion 5011 can abut against the connecting rod 302 .

[0174] When the passenger cancels the control of the adjustment part 5011, the adjustment part 5011 moves from the third position to the fourth position under the action of the elastic member 5012; the limiting member 51 moves from the second position to the first position under the action of the second driving member 502 to abut the connecting rod 302.

[0175] It should be noted that when the adjusting portion 5011 moves from the fourth position to the third position, it may abut against the limiting member 51 at the same time to drive the limiting member 51 to move, or it may abut against the limiting member 51 after moving a certain stroke to drive the limiting member 51 to move.

[0176] In some embodiments of the present application, the driving member 50 also includes a second driving member 502, at least part of which is disposed on the shell 52, for driving the limiting member 51 to move from the second position to the first position so that the limiting member 51 is separated from the connecting rod 302.

[0177] In some embodiments of the present application, the second driving member 502 includes a driving body 5021 and an output part 5022 connected to the driving body 5021, and the output part 5022 is connected to the limiting member 51 to drive the limiting member 51 to move from the first position to the second position; that is, in this embodiment, the second driving member 502 drives the limiting member 51 to move by electric drive. When the second driving member 502 drives the limiting member 51 to move to the second position, the connecting rod 302 moves in a direction close to the first main body part 11 or the second main body part 12 under the action of gravity, thereby realizing the storage of the seat body 1.

[0178] In addition, the provision of the second driving member 502 also enables the passenger to remove the connecting rod 302 from the housing 52 without operating the adjusting portion 5011 .

[0179] In some embodiments of the present application, the driving component 50 also includes a reset member 503, which is connected to the limiting member 51 to drive the limiting member 51 to move from the first position to the second position, that is, the reset member 503 is used to drive the limiting member 51 to abut against the connecting rod 302.

[0180] See also Figures 9 to 11In some embodiments of the present application, the second driving member 502 includes a second torsion spring 5031, and the second torsion spring 5031 is transmission-connected to the limiting member 51; wherein, the second torsion spring 5031 is in a first state when the limiting member 51 is in the first position, and is in a second state when the limiting member 51 is in the second position, and the compression amount of the second torsion spring 5031 in the second state is greater than the compression amount of the second torsion spring 5031 in the first state; that is, in this embodiment, when the limiting member 51 moves from the first position to the second position, the compression amount of the second torsion spring 5031 increases, and then when the adjusting part 5011 cancels the drive of the limiting member 51, the second torsion spring 5031 can drive the limiting member 51 to move from the second position to the first position due to its own deformation.

[0181] In some embodiments of the present application, one end of the second torsion spring 5031 is connected to the shell body 52, and the other end is connected to the limit member 51; by providing the second torsion spring 5031, when the adjustment part 5011 drives the limit member 51 to move from the first position to the second position, the second torsion spring 5031 will shrink; when the adjustment part 5011 cancels the drive to the limit member 51, the second torsion spring 5031 will return to its initial state, thereby driving the limit member 51 to move from the second position to the first position.
