[0033] The following is for reference. Figures 1-4The seat structure 100 according to the embodiment of the present utility model is simpler in overall structure and has a higher degree of integration. The seat frame body 1 can be flipped and stored through the first angle adjuster 3, and the seat structure 100 can be connected to the vehicle body through the mounting bracket 2. The installation process is simpler and more convenient, reducing installation and maintenance costs. The external structure is flat and simple, and the use effect is good.

[0034] like Figures 1-4 As shown, a seat structure 100 according to an embodiment of the present invention includes: a seat frame body 1, a mounting bracket 2, a first angle adjuster 3, and a first driving component 4.

[0035] The seat frame body 1 includes a backrest frame 11 and a seat cushion frame 12. The backrest frame 11 is rotatably connected to the seat cushion frame 12. The seat frame body 1 is the main frame structure of the seat structure 100, used to install and support other structures of the seat structure 100. The backrest frame 11 and the seat cushion frame 12 are the main components of the seat frame body 1. The backrest frame 11 is mainly used to support the back of the driver and passenger, reducing the pressure on the back during long-term driving or sitting. The seat cushion frame 12 is mainly used to support the legs and buttocks of the driver and passenger. The backrest frame 11 and the seat cushion frame 12 have sufficient structural strength to meet the riding needs and riding comfort of the driver and passenger.

[0036] Meanwhile, the backrest frame 11 is located on the upper side of the seat cushion frame 12. The backrest frame 11 is rotatably connected to the seat cushion frame 12, allowing the backrest frame 11 to rotate relative to the seat cushion frame 12. The backrest frame 11 can rotate relative to the seat cushion frame 12 in a direction that is closer to or farther away from the seat cushion frame 12. Therefore, when the seat structure 100 is applied to a vehicle, when the backrest frame 11 rotates to a certain angle relative to the seat cushion frame 12, it can be used for the driver and passengers to sit. When the backrest frame 11 rotates towards the seat cushion frame 12 and fits against the seat cushion frame 12, it can be used for the storage of the seat structure 100. It can be used for the driver and passengers to sit or lie down. Furthermore, the rotation of the backrest frame 11 relative to the seat cushion frame 12 can adjust the angle between the backrest frame 11 and the seat cushion frame 12 to meet the seating needs of different passengers. In this way, the comfort and versatility of the seat structure 100 can be improved.

[0037] It should be noted that the backrest frame 11 and the seat cushion frame 12 can be rotatably connected by an angle adjuster or other rotating mechanism.

[0038] The mounting bracket 2 is located below the seat cushion frame 12. The mounting bracket 2 is used to fix the seat cushion frame 12 relative to the floor. For example, the mounting bracket 2 can be connected to the bottom of the seat cushion frame 12 and can also be connected to the floor to connect the seat cushion frame 12 to the floor. Simultaneously, the mounting bracket 2 is fixedly connected to the floor, thus supporting the seat cushion frame 12 and, consequently, the seat structure 100. The mounting bracket 2 can be detachably connected to the floor using fasteners such as bolts, or it can be connected using snap-fit ​​or screw-fit methods.

[0039] Thus, by placing the mounting bracket 2 below the seat cushion frame 12, the mounting bracket 2 can be positioned close to the floor, facilitating the connection between the mounting bracket 2 and the floor, which in turn facilitates the connection between the seat structure 100 and the floor. Furthermore, by placing the connection structure between the seat structure 100 and the floor at the bottom of the seat structure 100, the seat structure 100 can be installed using the bottom, reducing the exposure of the connection structure and making the external structure of the seat structure 100 flat and simple.

[0040] The first adjuster 3 and the first drive member 4 are both installed inside the seat frame 12. The seat frame 12 is rotatably connected to the mounting bracket 2 via the first adjuster 3. The first drive member 4 is poweredly connected to the first adjuster 3 to drive the first adjuster 3 to rotate the seat frame 12 relative to the mounting bracket 2.

[0041] Specifically, the first angle adjuster 3 and the first drive component 4 are detachably connected to the seat frame 12, allowing the first angle adjuster 3 and the first drive component 4 to be installed using the internal space of the seat frame 12. This makes the internal structure of the seat frame 12 more compact and more integrated, and allows the first angle adjuster 3 and the first drive component 4 to be hidden inside the seat frame 12, so as to keep the external structure of the seat frame 12 flat and simple.

[0042] The first angle adjuster 3 adjusts the angle, and the first drive component 4 is a power source with a driving function. The first angle adjuster 3 is connected to the seat cushion frame 12, and the seat cushion frame 12 is also connected to the mounting bracket 2 through the first angle adjuster 3. Thus, the first angle adjuster 3 enables rotation between the seat cushion frame 12 and the mounting bracket 2. The first drive component 4 is powered by the first angle adjuster 3, so the driving force of the first drive component 4 can be transmitted to the first angle adjuster 3, which can drive the first angle adjuster 3 to rotate the seat cushion frame 12 relative to the mounting bracket 2. This enables the seat frame body 1 to rotate relative to the mounting bracket 2. Since the mounting bracket 2 is connected to the floor, the seat frame body 1 can rotate relative to the floor, so as to realize the flipping and storage or sitting use of the seat frame body 1. The flipping process uses the first angle adjuster 3, which makes the entire drive structure simpler, lowers the cost, and reduces the number of parts required for the flipping mechanism, thereby reducing the weight of the seat structure 100 and achieving lightweighting of the seat structure 100.

[0043] Therefore, by rotating the backrest frame 11 relative to the seat cushion frame 12, the angle between the backrest frame 11 and the seat cushion frame 12 can be adjusted, and by rotating the seat cushion frame 12 relative to the floor, the angle between the seat cushion frame 12 and the floor can be adjusted. In this way, the combined use of the backrest frame 11 and the seat cushion frame 12 can improve the riding comfort of the driver and passengers and meet the usage needs of different drivers and passengers.

[0044] The first angle adjuster 3 has a self-locking structure inside, which can lock the seat frame 12 when it rotates relative to the floor to the required angle, so as to maintain the stability of the angular posture of the seat frame 12 relative to the floor, improve the reliability and stability of the seat frame 12 adjustment, and the first angle adjuster 3 has a self-locking mechanism, so there is no need to set a separate locking structure between the floor and the seat frame 12, reducing the setting of locking structures and unlocking mechanisms, and reducing the setting cost of the seat structure 100.

[0045] According to the seat structure 100 of this utility model embodiment, by setting up a first angle adjuster 3, a first driving component 4, a mounting bracket 2 and a seat frame body 1 for cooperative use, the first driving component 4 can drive the first angle adjuster 3 to rotate the seat frame body 1 relative to the mounting bracket 2, which can realize the flipping and storage of the seat frame body 1. Moreover, the first angle adjuster 3 is cleverly used to realize the angle adjustment of the seat cushion frame 12, which can reduce the setting cost of the drive structure. The first angle adjuster 3 and the first driving component 4 are both installed inside the seat cushion frame 12, and the seat cushion frame 12 is connected to the mounting bracket 2 through the first angle adjuster 3, the first driving component 4, the seat cushion frame 12 and the mounting bracket 2 can be integrated into one unit. The seat structure 100 can be connected to the vehicle interior floor through the mounting bracket 2, which makes the installation process simpler and more convenient, reduces installation and maintenance costs, and has a high degree of overall structural integration, a flat and simple external structure, and better performance.

[0046] In some embodiments, the seat frame 12 has a connection socket 121, and the mounting bracket 2 includes a first connecting part 21, which extends into the connection socket 121 and is connected to the first angle adjuster 3.

[0047] Specifically, the first connecting part 21 extending to the connecting socket 121 is connected to the first adjuster 3, allowing the mounting bracket 2 to be connected to the first adjuster 3 via the first connecting part 21. The seat cushion frame 12 is also provided with a connecting socket 121, allowing the first connecting part 21 to pass through the connecting socket 121 and connect to the first adjuster 3 inside the seat cushion frame 12, facilitating the connection between the first connecting part 21 and the first adjuster 3. Furthermore, the mounting bracket 2 is connected to the floor, allowing the first adjuster 3 to be connected to the floor via the first connecting part 21, thereby enabling the seat cushion frame 12 to be rotatably connected to the floor via the first adjuster 3.

[0048] Among them, such as Figure 3 and Figure 4 As shown, a connecting slot 121 can be provided at the bottom of the seat cushion frame 12. The connecting slot 121 extends through the bottom of the seat cushion frame 12, allowing the first connecting part 21 to extend into the connecting slot 121 and connect to the first angle adjuster 3. The connecting slot 121 and the first connecting part 21 are designed to fit together, facilitating the insertion of the first connecting part 21 through the connecting slot 121 and reducing the opening size at the bottom of the seat cushion frame 12, resulting in higher structural integrity. Furthermore, the first connecting part 21 is positioned closer to the first angle adjuster 3, facilitating the connection between the first connecting part 21 and the first angle adjuster 3.

[0049] Furthermore, the first connecting part 21 can be constructed as a connecting plate. The first connecting part 21 and the first angle adjuster 3 can be detachably connected by fasteners such as bolts. This not only achieves the connection between the two, but also ensures high reliability through bolt connection, which is beneficial to improving the support strength of the seat frame 12 and improving the working stability and reliability of the first angle adjuster 3.

[0050] In some embodiments, the seat frame 12 is provided with a connecting seat 122, the connecting seat 122 having a second connecting portion 1221, and the first connecting portion 21 and the second connecting portion 1221 are arranged facing each other along the axial direction of the first drive member 4.

[0051] Specifically, the connecting seat 122 is provided with a second connecting part 1221 for connecting to the first angle adjuster 3, so that the connecting seat 122 can be connected to the first angle adjuster 3 through the second connecting part 1221. The connecting seat 122 is disposed inside the seat frame 12, so that the seat frame 12 can be connected to the first angle adjuster 3 through the second connecting part 1221. The second connecting part 1221 and the first connecting part 21 are distributed opposite each other along the axial direction of the first driving member 4. That is, at least a part of the connecting seat 122 and at least a part of the mounting bracket 2 can be distributed opposite each other along the axial direction of the first driving member 4, so that the connecting seat 122 and the mounting bracket 2 can be close to the output end of the first driving member 4, which facilitates the connection of the connecting seat 122 and the mounting bracket 2 to the first angle adjuster 3.

[0052] In actual design, the connecting seat 122 and the seat frame 12 can be integrally formed, or the connecting seat 122 and the seat frame 12 can be detachably connected.

[0053] The first angle adjuster 3 includes a first disc 31 and a second disc 32, which are rotatably connected. The first disc 31 is connected to the first connecting part 21, and the second disc 32 is connected to the second connecting part 1221.

[0054] Specifically, the first disc 31 and the second disc 32 rotate in coordination, so that the angle between them can be adjusted by the relative rotation of the first disc 31 and the second disc 32. It is possible to set one of the first disc 31 and the second disc 32 as a movable part and the other as a fixed part to facilitate relative rotation between the first disc 31 and the second disc 32. The following description takes the first disc 31 as a fixed part and the second disc 32 as a movable part as an example.

[0055] Furthermore, such as Figure 3As shown, connecting the first disc body 31 to the first connecting part 21 allows the first disc body 31 and the first connecting part 21 to be connected as one unit, thereby connecting the first disc body 31 to the mounting bracket 2 to fix the first angle adjuster 3. Connecting the second disc body 32 to the second connecting part 1221 allows the second disc body 32 and the second connecting part 1221 to be connected as one unit, thereby connecting the second disc body 32 to the connecting seat 122 to connect the seat frame 12 to the first angle adjuster 3.

[0056] Thus, when it is necessary to adjust the angle of the seat cushion frame 12 relative to the floor, the driving force of the first driving component 4 can be transmitted to the second disc 32, driving the second disc 32 to rotate relative to the first disc 31, which in turn drives the connecting seat 122 to rotate relative to the mounting bracket 2, thereby enabling the seat cushion frame 12 to rotate relative to the floor. Its structure is simple, assembly is convenient, and the rotation process is straightforward, which can shorten the flipping time of the seat frame body 1 and improve the adjustment efficiency of the seat frame body 1.

[0057] In some embodiments, there are two mounting brackets 2, two connecting seats 122, and two first angle adjusters 3. The first connecting parts 21 of the two mounting brackets 2, the second connecting parts 1221 of the two connecting seats 122, and the two first angle adjusters 3 are matched in a one-to-one correspondence. The first driving member 4 is located between the two connecting seats 122 and is connected to the two first angle adjusters 3 respectively.

[0058] Specifically, such as Figure 1 and Figure 2 As shown, the mounting bracket 2, connecting seat 122, and first angle adjuster 3 work together to form a set of angle adjustment mechanisms. Two mounting brackets 2, two connecting seats 122, and two first angle adjusters 3 are set up to cooperate in a one-to-one correspondence. That is, through the one-to-one cooperation of the first connecting part 21 of the two mounting brackets 2, the two connecting seats 122, and the two first angle adjusters 3, two sets of angle adjustment mechanisms can be formed. The mounting bracket 2 is connected to the floor, and the connecting seat 122 is connected to the seat cushion frame 12. The angle of the seat cushion frame 12 relative to the floor can be adjusted by the two sets of angle adjustment mechanisms, which can improve the angle adjustment efficiency of the seat cushion frame 12.

[0059] Among them, such as Figure 2 As shown, the first driving member 4 is located between the two connecting seats 122, which allows the first driving member 4 to be arranged between the two connecting seats 122. The first driving member 4 is connected to the two first angle adjusters 3 respectively, so that the output end of the first driving member 4 is connected to the two first angle adjusters 3 respectively, so that the driving force of the first driving member 4 can be transmitted to the two first angle adjusters 3, and the first driving member 4 can drive the two first angle adjusters 3 to move simultaneously.

[0060] Therefore, through the above arrangement, the first driving component 4 occupies the space between the two connecting seats 122, allowing the first driving component 4 to be close to the two first angle adjusters 3, facilitating the connection between the first driving component 4 and the two first angle adjusters 3. Furthermore, the overall arrangement of the first driving component 4 and the two sets of angle adjuster mechanisms is more compact, and all structures are located within the seat cushion frame 12, resulting in a flat and simple external structure of the seat cushion frame 12. Moreover, the first driving component 4 can be configured as a single unit, reducing the number of driving structures required and lowering installation costs.

[0061] It should also be noted that the two mounting brackets 2, the two connecting seats 122 and the two first angle adjusters 3 are spaced apart at both ends of the lateral side of the seat cushion frame 12, and the two mounting brackets 2, the two connecting seats 122 and the two first angle adjusters 3 can be symmetrically distributed along the lateral side of the seat cushion frame 12, so that the overall structure of the seat cushion frame 12 is symmetrical and regular.

[0062] In some embodiments, the seat structure 100 further includes a drive shaft 5, which is connected between the second discs 32 of the two first angle adjusters 3, and the drive shaft 5 passes through the first connecting portion 21.

[0063] Specifically, the drive shaft 5 has the function of transmitting power, such as Figure 3 and Figure 4 As shown, the drive shaft 5 is connected between the second discs 32 of the two first angle adjusters 3. This allows the drive shaft 5 to be positioned between the two second discs 32, and the driving force at the drive shaft 5 can be transmitted to the second discs 32 of the two first angle adjusters 3 respectively, enabling the two second discs 32 to rotate relative to their corresponding first discs 31, thus fulfilling the rotation requirements of the two first angle adjusters 3. Furthermore, the drive shaft 5 passes through the first connecting part 21, allowing it to be close to the second discs 32, facilitating connection between the output end of the drive shaft 5 and the second discs 32. Both axial ends of the drive shaft 5 pass through the two first connecting parts 21 and connect to the two second discs 32. The drive shaft 5 and the first connecting parts 21 can be spaced apart circumferentially along the drive shaft 5, thus avoiding interference between the drive shaft 5 and the first connecting parts 21 during movement and ensuring the stability of the seat frame 12 during its flipping process.

[0064] Furthermore, the drive shaft 5 passes through the first connecting part 21 and is connected to the second disc body 32. The first connecting part 21 is used to connect to the first disc body 31, and the second connecting part 1221 is used to connect to the second disc body 32. In this way, the two first connecting parts 21 are arranged circumferentially between the two second connecting parts 1221, and at least part of the two first connecting parts 21 are located inside the seat frame 12, reducing the exposure of the connection structure of the two first angle adjusters 3. This is beneficial to improving the integrated setting of the internal structure of the seat frame 12 and can keep the external structure of the seat frame 12 flatter.

[0065] In some embodiments, the output end of the first driving member 4 is provided with a driving gear ring 41, which is sleeved on the outside of the transmission shaft 5 and engages with the transmission shaft 5 in a circumferential transmission manner.

[0066] Specifically, the drive gear ring 41 is located at the output end of the first drive member 4, meaning that the power of the first drive member 4 is output through the drive gear ring 41. Furthermore, by sleeved around the transmission shaft 5, the drive gear ring 41 and the transmission shaft 5 can achieve circumferential transmission cooperation. This sleeved connection improves the reliability of their circumferential cooperation, thereby enhancing the reliability of power transmission between them. In practical use, the driving force of the first drive member 4 is transmitted to the drive gear ring 41. The rotation of the drive gear ring 41 drives the transmission shaft 5 to rotate, and since the transmission shaft 5 is connected to the two first angle adjusters 3, the rotation of the two first angle adjusters 3 can be achieved.

[0067] In the actual design, a spline groove can be set in the center of the drive gear ring 41, and the transmission shaft 5 can be constructed as a spline shaft, which can realize the transmission cooperation between the drive gear ring 41 and the spline shaft. The spline cooperation can effectively improve the installation accuracy of the drive gear ring 41 and the transmission shaft 5, and has a strong load-bearing capacity. It can effectively improve the reliability of power transmission from the drive gear ring 41 to the transmission shaft 5, and thus effectively improve the reliability of the first drive component 4 driving the first angle adjuster 3 to move.

[0068] It should be noted that the first driving component 4 may include a drive motor and a reduction mechanism. The output end of the reduction mechanism is connected to the transmission shaft 5. Through the cooperation of the drive motor and the reduction mechanism, the power required for the rotation of the first angle adjuster 3 can be met, so as to ensure the stable rotation of the first angle adjuster 3.

[0069] In some embodiments, the connecting seat 122 further has a third connecting portion 1222, which is used for rotatably connecting with the backrest frame 11.

[0070] Specifically, such as Figure 3 As shown, the connecting seat 122 is provided with a third connecting part 1222 for connecting with the backrest frame 11. This allows the connecting seat 122 to be connected to the backrest frame 11 via the third connecting part 1222. By rotatably connecting the third connecting part 1222 to the backrest frame 11, the backrest frame 11 and the third connecting part 1222 can rotate relative to each other, thereby achieving relative rotation between the backrest frame 11 and the connecting seat 122. Furthermore, the connecting seat 122 is connected to the seat cushion frame 12. Thus, through the connecting action of the third connecting part 1222, relative rotation between the backrest frame 11 and the seat cushion frame 12 can be achieved.

[0071] It should be noted that the third connecting part 1222 can be spaced apart from the second connecting part 1221 and distributed on the connecting seat 122. The connecting seat 122 is connected to the first angle adjuster 3 through the second connecting part 1221 and to the backrest frame 11 through the third connecting part 1222. The connecting seat 122 is also connected to the seat cushion frame 12. In this way, the connection between the three structures can be realized through one connecting seat 122, and the relative movement between the backrest frame 11 and the seat cushion frame 12 and the movement of the seat cushion frame 12 relative to the floor can be realized. The overall structure is simpler, easier to assemble, and easier to maintain.

[0072] In some embodiments, the seat structure 100 further includes a second adjuster 6 and a second drive member 7. The second drive member 7 is located inside the backrest frame 11. A portion of the second adjuster 6 is connected to the first drive member 4 and another portion is connected to the third connecting portion 1222. The second drive member 7 is used to drive the second adjuster 6 to rotate the backrest frame 11 relative to the third connecting portion 1222.

[0073] Specifically, such as Figure 2 As shown, the second drive component 7 is located inside the backrest frame 11. If the second drive component 7 can be detachably connected to the backrest frame 11, it can utilize the internal space of the backrest frame 11 for installation, resulting in a more compact and integrated internal structure. Simultaneously, a portion of the second angle adjuster 6 is connected to the first drive component 4, and another portion is connected to the third connecting part 1222. This allows the second drive component 7 to connect to the connecting seat 122 via the second angle adjuster 6. In practical design, an installation space can be formed on the outside of the backrest frame 11, with the second angle adjuster 6 located in this space. The second angle adjuster 6 is encased in a shell to conceal and protect it, and the shell matches the shape of the backrest frame 11, improving their coordination and flatness. Thus, through the above arrangement, the first drive component 4 can be hidden inside the seat cushion frame 12, maintaining a flat and simple external structure for the seat cushion frame 12.

[0074] The second angle adjuster 6 adjusts the angle, and the second drive unit 7 is a power source with a driving function. The second angle adjuster 6 is connected to the backrest frame 11, and the backrest frame 11 is also connected to the connecting seat 122 through the second angle adjuster 6. Thus, the rotation between the backrest frame 11 and the connecting seat 122 can be realized through the second angle adjuster 6. The second drive unit 7 is poweredly connected to the second angle adjuster 6, so the driving force of the second drive unit 7 can be transmitted to the second angle adjuster 6, which can drive the second angle adjuster 6 to rotate the backrest frame 11 relative to the connecting seat 122, thereby realizing the rotation of the backrest frame 11 relative to the seat cushion frame 12, so as to realize the flipping and storage or sitting use of the backrest frame 11. The flipping process uses the second angle adjuster 6, which makes the entire drive structure simpler and lower in cost.

[0075] Therefore, by rotating the backrest frame 11 relative to the seat cushion frame 12, the angle between the backrest frame 11 and the seat cushion frame 12 can be adjusted, and by rotating the seat cushion frame 12 relative to the floor, the angle between the seat cushion frame 12 and the floor can be adjusted. In this way, the combined use of the backrest frame 11 and the seat cushion frame 12 can improve the riding comfort of the driver and passengers and meet the usage needs of different drivers and passengers.

[0076] It should be noted that the arrangement of the second drive member 7 and the second adjuster 6 can be the same as the arrangement of the first drive member 4 and the first adjuster 3. That is, the second adjuster 6 can be constructed as two discs, and the second drive member 7 can be connected to the second adjuster 6 through the transmission shaft 5. There are two second adjusters 6, and the second drive member 7 can be set between the two second adjusters 6. The second drive member 7 can drive the movement of the two second adjusters 6 through the transmission shaft 5, so that the two second adjusters 6 can respectively drive the backrest frame 11 to rotate relative to the seat cushion frame 12.

[0077] It should also be noted that the second angle adjuster 6 is equipped with a self-locking structure, which can lock the backrest frame 11 relative to the seat cushion frame 12 when it is rotated to the required angle, so as to maintain the stability of the angle between the backrest frame 11 and the seat cushion frame 12 and improve the reliability and stability of the adjustment of the backrest frame 11.

[0078] In some embodiments, the seat structure 100 further includes a headrest 8, which is height-adjustable relative to the backrest frame 11. Specifically, the headrest 8 supports the head of the driver / passenger, reduces the burden on the neck muscles, alleviates neck fatigue, and reduces head movement during vehicle operation, thereby improving passenger comfort. Furthermore, the headrest 8 protects the driver / passenger's head from rear-end collisions, reducing head injuries. The height-adjustable connection of the headrest 8 to the backrest frame 11 allows adjustment of its height relative to the backrest frame 11 to meet the needs of different users. Adjusting the height of the headrest 8 relative to the backrest frame 11 also allows for storage or use while seated.

[0079] It should be noted that, as Figure 2 As shown, the headrest 8 can be connected to the top of the backrest frame 11 via a lifting mechanism 81. The lifting mechanism 81 can be used in conjunction with a drive motor and gear racks, worm gears, etc., to automatically drive the headrest 8 to rise and fall relative to the backrest frame 11. The lifting mechanism 81 can also be used to manually adjust the rise and fall of the headrest 8.

[0080] The seat structure 100 also includes a control module, which controls the headrest 8 to rise and fall relative to the backrest frame 11, controls the backrest frame 11 to rotate relative to the seat cushion frame 12, and controls the seat cushion frame 12 to rotate relative to the floor.

[0081] Specifically, the control module is used to control the flipping state of the seat frame body 1. For example, the control module can be electrically connected to the lifting mechanism 81 of the headrest 8, the second drive component 7 of the backrest frame 11, and the first drive component 4 of the seat cushion frame 12. This allows the control module to control the lifting mechanism 81 to raise and lower the headrest 8 relative to the backrest frame 11, control the second drive component 7 to drive the second adjuster 6 to rotate the backrest frame 11 relative to the seat cushion frame 12, and control the first drive component 4 to drive the first adjuster 3 to rotate the seat cushion frame 12 relative to the floor. The control module can perform these control processes individually or simultaneously according to usage requirements to meet different needs.

[0082] Simultaneously, when the seat frame 1 needs to be stored, the headrest 8 can be lowered relative to the backrest frame 11 for storage via the control module. The backrest frame 11 can also be moved closer to the seat cushion frame 12 for storage, and the seat cushion frame 12 can be flipped backward relative to the floor to be stored in the trunk at the rear of the vehicle, thus achieving a magical storage mechanism for the seat structure 100. Throughout the entire control process, the movements of the headrest 8, backrest frame 11, and seat cushion frame 12 can be synchronized to shorten the storage time of the seat frame 1 and improve the storage efficiency of the seat structure 100.

[0083] In this embodiment, by placing the first drive member 4 and the first angle adjuster 3 inside the seat cushion frame 12, and by placing the second drive member 7 inside the backrest frame 11, and by allowing the headrest 8 to rise and fall relative to the backrest frame 11, the overall vertical height of the seat structure 100 can be reduced. This reduces the vertical space occupied by the entire seat frame body 1 during the flipping and storage process of the seat structure 100. Furthermore, by pre-adjusting the headrest 8, the space occupied in the front-to-back direction during the flipping process of the seat frame body 1 can be further reduced, making it suitable for small vehicle spaces. The entire seat structure 100 has a high degree of integration, with no excessive protruding structures after flipping. When the seat structure 100 is stored, the interior space can be freed up, forming a continuous and regular large space for the placement of different items or for passenger rest, thus improving space utilization.

[0084] This utility model also proposes a vehicle.

[0085] According to the vehicle of this utility model embodiment, a seat structure 100 of any of the above embodiments is provided. The seat structure 100 can be applied to the first row, second row, or third row of seats in the vehicle, expanding the application scenarios of the seat structure 100. The seat structure 100 is provided with a seat cushion frame 12, a backrest frame 11, a headrest 8, a first angle adjuster 3, a first drive component 4, a second angle adjuster 6, and a second drive component 7. Through the cooperative use of the above structures, the headrest 8, the backrest frame 11, and the seat cushion frame 12 can be stored respectively. The first angle adjuster 3 and the first drive component 4 are both installed inside the seat cushion frame 12, which can integrate the first angle adjuster 3, the first drive component 4, the seat cushion frame 12, and the mounting bracket 2 into one unit. The seat structure 100 can be connected and fixed to the vehicle floor through the mounting bracket 2, which can realize the connection between the seat structure 100 and the vehicle body. The installation process is simpler and more convenient, reducing installation and maintenance costs. Moreover, the overall structure has a high degree of integration, a flat and simple external structure, and better performance.
