For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

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

[0042] like Figure 1 As shown, a seat frame 10 according to an 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. The seat frame 10 can stably support the weight of the seat assembly 100 and the passenger, ensuring that it is not 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 Figures 1-3 As shown, the support panel assembly 2 is arranged on the base 1. 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, a drive mechanism 3 is provided on the base 1 to raise or lower the support panel assembly 2. Passengers can adjust the height of the support panel assembly 2 to meet their needs. A leg rest adjustment panel 4 is provided on the base 1 and connected to the support panel assembly 2. This increases the support area for the passenger's legs, providing better support for their legs during the ride and reducing leg fatigue.

[0047] The leg rest adjustment panel 4 is configured to move rearward at its upper end when the support panel assembly 2 is raised, allowing for personalized adjustments based on the body shape and needs of different passengers. Regardless of height, weight, or size, passengers can adjust the leg rest adjustment panel 4 to find the most comfortable sitting position for them, providing a more pleasant and comfortable ride in the vehicle seat assembly 100. This personalized design makes the vehicle seat assembly 100 more ergonomically sound and provides more attentive service to passengers.

[0048] Specifically, a rotating rod 41 is fixed to the upper end of the leg rest adjustment panel 4, which 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 about the rotating rod 41, and the leg rest adjustment panel 4 can be adjusted to a position that matches the support panel assembly 2, achieving ergonomic seat support for the passenger.

[0049] 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 to realize 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. 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, so that the passengers have a higher riding comfort.

[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 by a connecting rod mechanism 5.

The two groups of connecting rod mechanisms 5 can better support the support panel assembly 2 and the leg rest adjusting panel 4, so that the positions of the support panel assembly 2 and the leg rest adjusting panel 4 are more reliable, and the seat framework 10 has a better support effect on the passenger.

[0054] Further, as shown in Figure 3 and Figure 4 , the first connecting rod mechanism 51 includes a front connecting rod 511, a rear connecting rod 512 and an upper connecting rod 513.

[0055] Further, as shown in Figure 3 and Figure 4 the driving mechanism 3 comprises an angle adjusting disc 31 and a driving motor 32, the angle adjusting disc 31 is rotatably arranged on the base 1, and the angle adjusting disc 31 is fixedly connected with 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 with the angle adjusting disc 31, and is used for driving the angle adjusting disc 31 to rotate. The driving motor 32 drives the angle adjusting disc 31 to rotate, the automation of the driving mechanism 3 can be realized, the angle adjusting disc 31 is fixedly connected with the front connecting rod 511, when the driving motor 32 drives the angle adjusting disc 31 to rotate, the front connecting rod 511 rotates, the front connecting rod 511 rotates relative to the base 1, the front connecting rod 511 drives the upper connecting rod 513 to move, the rear connecting rod 512 rotates relative to the base 1, the lifting or lowering of the upper connecting rod 513 is realized, and the lifting or lowering of the support panel assembly 2 fixedly connected with the upper connecting rod 513 is realized.

[0056] Specifically, as shown in Figure 3 and Figure 4 the angle adjusting disc 31 is two, and is arranged on two bases 1 respectively, a connecting rod 33 is arranged between the two angle adjusting discs 31, the driving motor 32 is connected with one of the angle adjusting discs 31, and the two angle adjusting discs 31 rotate synchronously under the driving action of the connecting rod 33, the driving of the two groups of first driving mechanisms 3 can be realized.
