For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Reference below Figure 1-Figure 5 A seat frame 10 according to an embodiment of the present invention is described.

[0042] like Figure 1 As shown, the seat frame 10 according to the embodiment of the present invention includes a base 1, a support panel assembly 2, a driving mechanism 3, a leg support adjustment panel 4 and a connecting rod mechanism.

[0043] Specifically, the seat frame 10 is used in a vehicle, and the seat frame 10 can stably support the weight of the seat assembly 100 and the passengers, ensuring that it will not be deformed or damaged during driving, and has good load-bearing capacity.

[0044] The base 1 can be fixed on the vehicle body, and the seat frame 10 can be installed on the vehicle body to achieve a force transmission effect with the vehicle body. When a vehicle collision accident occurs, the seat frame 10 can absorb part of the impact energy and provide necessary protection for passengers through its sturdy structure to reduce the risk of injury.

[0045] like Figure 1-Figure 3 As shown, the support panel assembly 2 is arranged on the base 1, and the support panel assembly 2 is used as the main force-bearing part when the passenger sits on the seat, contacting the passenger's buttocks and thighs and providing support.

[0046] Furthermore, the driving mechanism 3 is arranged on the base 1, and is used to drive the support panel assembly 2 to rise or fall, and the passenger can adjust the height of the support panel assembly 2 according to their needs to meet the different needs of the passengers. The leg rest adjustment panel 4 is arranged on the base 1 and connected to the support panel assembly 2. The leg rest adjustment panel 4 can increase the support area of ​​the passenger's legs, so that the passenger's legs can be better supported during the ride, thereby reducing leg fatigue.

[0047] The leg rest adjustment panel 4 is configured to move the upper end backward when the support panel assembly 2 is raised, and can be adjusted according to the stature and needs of different passengers. Regardless of height, weight or thinness, passengers can find the most suitable sitting posture by adjusting the leg rest adjustment panel 4, and passengers can enjoy a more pleasant and comfortable riding experience on the vehicle seat assembly 100. This personalized design makes the vehicle seat assembly 100 more ergonomic and provides more considerate services for passengers.

[0048] Specifically, a rotating rod 41 is fixed to the upper end of the leg rest adjustment panel 4, and the rotating rod 41 is rotatably connected to the front end of the support panel assembly 2. When the support panel assembly 2 is raised or lowered, the leg rest adjustment panel 4 can rotate around the rotating rod 41 as an axis, and the leg rest adjustment panel 4 can be adjusted to a position that matches the support panel assembly 2, thereby achieving ergonomic seat support for passengers.

[0049] In addition, the leg rest adjustment panel 4 is constructed so that the upper end moves backward when the support panel assembly 2 is lifted. At this time, the lower end position of the leg rest adjustment panel 4 remains unchanged, and the leg rest adjustment panel 4 rotates, thereby realizing the angle adjustment function of the leg rest adjustment panel 4. When the support panel assembly 2 is displaced, the upper end of the leg rest adjustment panel 4 can move forward or backward according to the displacement of the support panel assembly 2, and the leg rest adjustment panel 4 can adjust its own position and angle according to the displacement direction of the support panel assembly 2, so that the leg rest adjustment panel 4 and the support panel assembly 2 can maintain a more ergonomic shape, thereby increasing the riding comfort of passengers.

[0050] In addition, the adjustment of the leg rest adjustment panel 4 can be driven by the movement of the support panel assembly 2. The adjustment of the leg rest adjustment panel 4 does not require the addition of other driving structures. The manufacturing cost of the seat frame 10 is low, and the adjustment of the leg rest adjustment panel 4 is more convenient.

[0051] The base 1, the support panel assembly 2 and the leg rest adjustment panel 4 are connected together through a connecting rod mechanism 5. The base 1 can provide support for the support panel assembly 2 and the leg rest adjustment panel 4, so as to facilitate the assembly of the seat frame 10. And the connecting rod mechanism 5 facilitates the driving of the leg rest adjustment panel 4 by the support panel assembly 2. The connecting rod mechanism 5 includes a first connecting rod mechanism 51, which connects the base 1 and the support panel assembly 2. The driving mechanism 3 is used to drive the first connecting rod mechanism 51 to move so as to drive the support panel assembly 2 to rise or fall. The first connecting rod mechanism 51 can convert the kinetic energy of the driving mechanism 3 into the kinetic energy of the support panel assembly 2, so as to realize the driving of the support panel assembly 2 and increase the driving reliability of the support panel assembly 2.

[0052] According to the seat frame 10 of the embodiment of the present invention, the driving mechanism 3 is arranged on the base 1 to drive the support panel assembly 2 to be lifted or lowered, the leg rest adjustment panel 4 is arranged on the base 1 and connected to the support panel assembly 2, and the rotating rod 41 at the upper end of the leg rest adjustment panel 4 is rotatably connected to the front end of the support panel assembly 2. When the support panel assembly 2 is lifted or lowered, the leg rest adjustment panel 4 can rotate with the rotating rod 41 as the axis, and the leg rest adjustment panel 4 can be adjusted to a position that matches the support panel assembly 2 to achieve ergonomic seat support for passengers. The first connecting rod mechanism 51 connects the base 1 and the support panel assembly 2, and the driving mechanism 3 is used to drive the first connecting rod mechanism 51 to move to drive the support panel assembly 2 to be lifted or lowered. The first connecting rod mechanism 51 can convert the kinetic energy of the driving mechanism 3 into the kinetic energy of the support panel assembly 2, realize the driving of the support panel assembly 2, and increase the reliability of the driving of the support panel assembly 2. The leg rest adjustment panel 4 of the seat frame 100 can be adjusted by the movement of the support panel assembly 2. The leg rest adjustment panel 4 does not require the addition of other driving structures, and the manufacturing cost of the seat frame 100 is relatively low.

[0053] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the base 1 is along the left and right directions (such as Figure 1 The connecting rod mechanisms 5 are two groups spaced apart along the left and right directions corresponding to the base 1. The two groups of connecting rod mechanisms 5 can better support the support panel assembly 2 and the leg rest adjustment panel 4, so that the positions of the support panel assembly 2 and the leg rest adjustment panel 4 are more reliable, and the seat frame 10 has a better supporting effect on the passengers.

[0054] Furthermore, if Figure 3 and Figure 4 As shown, the first link mechanism 51 includes a front link 511, a rear link 512 and an upper link 513. The length direction of the front link 511 (eg Figure 1 One end of the rear connecting rod 512 in the length direction is rotatably connected to the base 1 and is located at the rear side of the front connecting rod 511. Figure 1The two ends of the front connecting rod 511 (shown in the fourth direction) are respectively rotatably connected to the end of the front connecting rod 511 away from the base 1 and the end of the rear connecting rod 512 away from the base 1, and the upper connecting rod 513 is fixedly connected to the support panel assembly 2. It can be understood that the driving mechanism 3 drives the front connecting rod 511 to rotate, the front connecting rod 511 is rotatably connected to the upper connecting rod 513, the rear connecting rod 512 is rotatably connected to the upper connecting rod 513 and the base 1, the front connecting rod 511 and the rear connecting rod 512 support the upper connecting rod 513, when the front connecting rod 511 rotates, the front connecting rod 511 and the base 1 rotate relatively, the front connecting rod 511 drives the upper connecting rod 513 to move, the rear connecting rod 512 rotates relatively with the base 1, the upper connecting rod 513 is lifted or lowered, and then the support panel assembly 2 fixedly connected to the upper connecting rod 513 is lifted or lowered.

[0055] Furthermore, if Figure 3 and Figure 4 As shown, the driving mechanism 3 includes an angle adjustment disc 31 and a driving motor 32. The angle adjustment disc 31 is rotatably arranged on the base 1. The angle adjustment disc 31 is fixedly connected to one end of the front connecting rod 511 away from the upper connecting rod 513. The driving motor 32 is arranged on the base 1 and connected to the angle adjustment disc 31, and is used to drive the angle adjustment disc 31 to rotate. The driving motor 32 drives the angle adjustment disc 31 to rotate, which can realize the automation of the driving mechanism 3. The angle adjustment disc 31 is fixedly connected to the front connecting rod 511. When the driving motor 32 drives the angle adjustment disc 31 to rotate, the front connecting rod 511 rotates accordingly, and the front connecting rod 511 and the base 1 rotate relatively. The front connecting rod 511 drives the upper connecting rod 513 to move, and the rear connecting rod 512 rotates relatively with the base 1 to realize the lifting or lowering of the upper connecting rod 513, thereby realizing the lifting or lowering of the support panel assembly 2 fixedly connected to the upper connecting rod 513.

[0056] Specifically, Figure 3 and Figure 4 As shown, there are two angle adjustment discs 31, which are respectively arranged on two bases 1, and a connecting rod 33 is provided between the two angle adjustment discs 31. The driving motor 32 is connected to one of the angle adjustment discs 31. Under the driving action of the connecting rod 33, the two angle adjustment discs 31 rotate synchronously, and the driving of the two groups of first driving mechanisms 3 can be realized.

[0057] By adjusting the drive motor 32, the passenger can control the forward rotation, reverse rotation and stop of the drive motor 32 according to his / her needs, adjust the height of the support panel assembly 2, obtain the height required by the passenger, and meet the passenger's field of vision, safe seat belt 30 position and riding comfort requirements.

[0058] Furthermore, if Figure 4As shown, the connecting rod mechanism 5 also includes an angle adjustment connecting rod 52, one end of the angle adjustment connecting rod 52 in the length direction is rotatably connected to the base 1, and the leg support adjustment panel 4 is provided with an adjustment guide groove 42, which extends along the width direction of the leg support adjustment panel 4. Figure 1 The other end (in the third direction shown) is slidably and rotatably arranged in the adjustment guide slot 42. The angle adjustment link 52 can provide support for the leg support adjustment panel 4, and the angle adjustment link 52 limits the rotation position of the leg support adjustment panel 4 by cooperating with the adjustment guide slot 42, thereby increasing the reliability of the displacement of the leg support adjustment panel 4.

The connecting rod mechanism 5 also includes a second connecting rod mechanism 53. The leg rest extension panel 6 is connected to the support panel assembly 2 through the second connecting rod mechanism 53, so that it can move downward when the support panel assembly 2 is lifted. When the support panel assembly 2 is lifted, the leg rest adjustment panel 4 rotates upward, and the leg rest extension panel 6 can move downward. The passenger is half lying on the seat frame 10, and the passenger's legs can be better supported. When the support panel assembly 2 is lowered, the leg rest adjustment panel 4 rotates downward, and the leg rest extension panel 6 can move upward to avoid the floor of the vehicle, and the passenger sits on the seat frame 10.

[0060] Furthermore, if Figure 4 As shown, the second link mechanism 53 includes a front cross bar 531, a cross bar bracket 532 and an extension link 533.
