[0031] The following reference Figures 1 - 6Describing the seat cushion assembly 100 according to an embodiment of the present utility model, when the seat cushion 11 is lifted, the leg rest plate 13 can slide out or be pushed into the seat cushion mounting skeleton 14, and the leg rest plate 13 can rotate relative to the seat cushion mounting skeleton 14 after sliding out, so that the leg rest plate 13 forms a comfortable state for supporting the occupant's legs. The structure of the leg rest plate 13 is simple and the operation is simple.

[0032] As Figures 1 - 6 shown, the seat cushion assembly 100 according to an embodiment of the present utility model includes: a seat cushion mounting skeleton 14, a seat cushion 11 and a leg rest plate 13.

[0033] Among them, an installation space is provided inside the seat cushion mounting skeleton 14, the seat cushion 11 is rotatably mounted above the seat cushion mounting skeleton 14, and the seat cushion 11 is adapted to be lifted or lowered relative to the seat cushion mounting skeleton 14; when the leg rest plate 13 is installed in the installation space, it is hidden under the seat cushion 11; among them, a sliding groove 140 is provided on the side of the seat cushion mounting skeleton 14, a rotating shaft 132 is provided on the outer side of the leg rest plate 13, the rotating shaft 132 slides along the sliding groove 140, a baffle 111 is provided on the side of the seat cushion 11, when the leg rest plate 13 is located in the installation space, the baffle 111 limits the rotating shaft 132, after the seat cushion 11 is lifted, the baffle 111 releases the limit on the rotating shaft 132, and the leg rest plate 13 can slide out or be pushed into the seat cushion mounting skeleton 14, and the leg rest plate 13 is adapted to rotate downward along the sliding groove 140 after sliding out in place.

[0034] In practice, the seat 1 includes a seat cushion 11 and a seat backrest 12, the seat 1 is installed on the body floor 2, and the seat cushion 11 is installed on the seat cushion mounting skeleton 14 and supported by the seat cushion mounting skeleton 14, that is, the leg rest plate 13 is movably installed on the seat cushion mounting skeleton 14. When the occupant does not use the leg rest plate 13, the leg rest plate 13 is hidden under the seat cushion 11. When the occupant needs to use the leg rest plate 13, the leg rest plate 13 is slid out along the seat cushion mounting skeleton 14, and the leg rest plate 13 is rotated downward after sliding out, so that the leg rest plate 13 is adjusted to a suitable position to improve the comfort of the occupant's legs.

[0035] Further, during actual operation, lifting the seat cushion 11 can slide out the leg rest plate 13, and then rotate the leg rest plate 13 downward; that is to say, when the seat cushion 11 is not lifted, the baffle 111 of the seat cushion 11 can limit the rotation shaft 132 to limit the leg rest plate 13, and when the seat cushion 11 is lifted and the baffle 111 does not limit the rotation shaft 132, the leg rest plate 13 can slide out smoothly. In addition, lifting the seat cushion 11 is also convenient for observing the state of the leg rest plate 13 during the sliding out process. When the leg rest plate 13 is not in use, first rotate the leg rest plate 13 upward to make the leg rest plate 13 return to a position where it is easy to slide along the seat cushion mounting skeleton 14, and then push the leg rest plate 13 to slide the leg rest plate 13 toward the position close to the seat back 12, and lower the seat cushion 11 to limit the leg rest plate 13, so that the leg rest plate 13 is hidden under the seat cushion 11.

[0036] In addition, the seat cushion mounting skeleton 14 is provided with an opening that opens toward the outside of the seat cushion 11, and the seat cushion 11 is provided with an installation space. Referring to Figure 3 As shown, the seat cushion mounting skeleton 14 includes a top plate 142 and two side plates 141. The two side plates 141 are respectively connected to both sides of the top plate 142 and extend downward. The two side plates 141 and the top plate 142 form an installation space. Each side plate 141 is provided with a sliding groove 140. Both sides of the leg rest plate 13 are provided with rotation shafts 132. When the leg rest plate 13 slides out or is pushed into the installation space of the seat cushion mounting skeleton 14, the rotation shafts 132 can slide along the sliding grooves 140, so that the leg rest plate 13 can slide smoothly. And when the leg rest plate 13 slides out, the rotation shafts 132 can rotate downward along the sliding grooves 140; when it is necessary to retract the leg rest plate 13, the rotation shafts 132 rotate upward along the sliding grooves 140, and the leg rest plate 13 is pushed into the installation space so that the leg rest plate 13 is hidden under the seat cushion 11.

[0037] That is to say, by setting the installation space, the leg rest plate 13 can be hidden in the seat cushion mounting skeleton 14, so as to be hidden under the seat cushion 11 when the seat cushion 11 is lowered. At the same time, the cooperation of the rotation shafts 132 and the sliding grooves 140 can make the leg rest plate 13 more smoothly pushed into or slid out from under the seat cushion 11.

[0038] Therefore, the leg rest plate 13 of the embodiment of the present utility model is different from the multi-link mechanism used in the prior art. The leg rest plate 13 has a simple structure and is convenient to operate. When in use, lift the seat cushion 11 to slide out the leg rest plate 13 and rotate it downward to keep the legs of the occupant in a comfortable state, and no electric control is required, and manual operation is sufficient, reducing the use of electric energy. And when not in use, first lift the seat cushion 11, and then rotate the leg rest plate 13 upward and push it to the bottom of the seat cushion 11 to save space.

[0039] In some embodiments, after the leg rest plate 13 slides out relative to the seat cushion mounting frame 14, it is in the slid-out state, and after being pushed in, it is in the hidden state. The sliding groove 140 includes a main groove 1401, a front-end groove 1402, and a rear-end groove 1404. The main groove 1401 extends along the front-rear direction of the seat cushion 11. The front-end groove 1402 and the rear-end groove 1404 are respectively located at the front end and the rear end of the main groove 1401. When the leg rest plate 13 is in the slid-out state, the rotating shaft 132 is rotatable within the front-end groove 1402. The rear-end groove 1404 extends rearward along the main groove 1401. A resisting portion 1405 is formed between the rear-end groove 1404 and the main groove 1401. When the leg rest plate 13 is in the hidden state, the rotating shaft 132 is pressed against the resisting portion 1405.

[0040] Specifically, the front-end groove 1402 refers to the position of the seat cushion 11 away from the seat backrest 12, and the rear-end groove 1404 refers to the position close to the seat backrest 12. When the leg rest plate 13 slides out from within the seat cushion mounting frame 14, the rotating shaft 132 of the leg rest plate 13 slides along the main groove 1401 into the front-end groove 1402, and the rotating shaft 132 slides from the main groove 1401 into the front-end groove 1402 and rotates downward within the front-end groove 1402, so as to support the legs of the occupant by the leg rest plate 13 and improve the comfort of the occupant's legs.

[0041] Combined Figure 3 and Figure 4 As shown in the figure, when the leg rest plate 13 returns from the slid-out state to the hidden state, the leg rest plate 13 rotates upward, causing the rotating shaft 132 to rotate upward within the front-end groove 1402. Then, the leg rest plate 13 is pushed, so that the leg rest plate 13 approaches the position of the rear-end groove 1404. The height of the main groove 1401 is smaller than the height of the main groove 1401, thereby forming a resisting portion 1405 at the junction of the front-end groove 1402 and the main groove 1401. After the leg rest plate 13 moves downward under the seat cushion 11 in the direction close to the seat backrest 12, the rotating shaft 132 abuts against the resisting portion 1405. At this time, the leg rest plate 13 is pushed into place towards the inside of the seat cushion mounting frame 14. Thus, by setting the front-end groove 1402 and the rear-end groove 1404, the front-end groove 1402 can limit the outward sliding of the leg rest plate 13, and at the same time provide a rotating space for the rotating shaft 132 of the leg rest plate 13, facilitating the adjustment of the state of the leg rest plate 13. The setting of the rear-end groove 1404 facilitates the formation of the resisting portion 1405 between the rear-end groove 1404 and the main groove 1401 to limit the backward pushing of the leg rest plate 13.

[0042] In some embodiments, the front-end groove 1402 is configured to be inclined downward along the main groove 1401.

[0043] In practice, when the front slot 1402 slopes downward along the main body slot 1401, after the leg rest plate 13 slides out, the rotating shaft 132 slides from the main body slot 1401 to the bottom of the front slot 1402, that is, the rotating shaft 132 moves downward, thereby reducing the height of the leg rest plate 13. Subsequently, the rotating shaft 132 of the leg rest plate 13 rotates within the front slot 1402 to cause the leg rest plate 13 to rotate downward, so that the leg rest plate 13 moves to a suitable position to support the legs of the occupant, improving the comfort of the occupant's legs.

[0044] In some embodiments, the seat cushion assembly 100 further includes a limit pin 131. The limit pin 131 is connected to the outer side wall of the leg rest plate 13 and is spaced parallel to the rotating shaft 132. A clamping interface 1403 is provided at the top of one end of the main body slot 1401 close to the front slot 1402. When the leg rest plate 13 is in the slid-out state and the rotating shaft 132 rotates to the lowest position within the front slot 1402, the limit pin 131 is clamped in the clamping interface 1403 for limiting.

[0045] In practice, after the leg rest plate 13 slides out relative to the seat cushion mounting frame 14, the rotating shaft 132 is located within the front slot 1402 of the sliding slot 140 and presses against the bottom wall of the sliding slot 140. When the leg rest plate 13 rotates downward, the rotating shaft 132 rotates within the front slot 1402 of the sliding slot 140. At this time, the limit pin 131 is clamped in the clamping interface 1403 as the leg rest plate 13 rotates, thereby preventing the leg rest plate 13 from continuing to rotate downward and improving the stability of the leg rest plate 13.

[0046] Wherein, rotating shafts 132 and limit pins 131 are provided on both sides of the leg rest plate 13. The positional relationship between the rotating shaft 132 and the limit pin 131 on each side is the same, and sliding slots 140 are provided on both sides of the seat cushion mounting frame 14. The shapes of the sliding slots 140 designed on each side are the same, and a clamping interface 1403 is provided on each sliding slot 140. Thus, the rotating shafts 132 on both sides of the leg rest plate 13 can slide and rotate along the corresponding sliding slots 140, and the limit pins 131 on both sides of the leg rest plate 13 can also be correspondingly clamped in the clamping interfaces 1403 of the corresponding sliding slots 140, improving the smoothness of the movement of the leg rest plate 13 and also limiting the downward rotation angle of the leg rest plate 13.

[0047] In some embodiments, when the leg rest plate 13 is in the hidden state, the rotating shaft 132 presses against the resisting portion 1405 and the limit pin 131 is located within the rear slot 1404 and presses against the inner wall of the rear slot 1404.

[0048] Specifically, when the leg rest plate 13 moves from the extended state to the hidden state, the leg rest plate 13 rotates upward, the limit pin 131 disengages from the clamping interface 1403, and after the leg rest plate 13 is pushed into the installation space in the direction close to the seat backrest 12 and is in place, when the rotating shaft 132 abuts against the abutting portion 1405, the limit pin 131 abuts in the rear end groove 1404. That is to say, in actual design, the height of the limit pin 131 designed along the height direction of the seat 1 is slightly higher than that of the rotating shaft 132, so that the limit pin 131 can be located in the rear end groove 1404, and the rotating shaft 132 abuts against the abutting portion 1405, limiting the sliding distance of the leg rest plate 13 in the direction close to the seat backrest 12.

[0049] In some embodiments, the baffle 111 is provided with limit openings 112 at the front and rear positions of the seat cushion 11. When the leg rest plate 13 slides to the hidden state, the seat cushion 11 is lowered and the rotating shaft 132 extends out of the limit opening 112 at the rear end, so that the baffle 111 limits the leg rest plate 13. When the leg rest plate 13 slides to the extended state, the seat cushion 11 is lowered and the baffle 111 presses against the limit pin 131 at the limit opening 112 at the front end to limit the leg rest plate 13.

[0050] In practice, there are two baffles 111 on the seat cushion 11, and they are respectively located on both sides of the seat cushion 11. Each baffle 111 is fixedly connected to the seat cushion 11. When the leg rest plate 13 is in the hidden position, after the seat cushion 11 is lowered, the rotating shaft 132 extends into the limit opening 112 at the rear end of the baffle 111, so that the baffle 111 limits the rotating shaft 132 through the limit opening 112 at the rear end to prevent the rotating shaft 132 from moving forward, so that the leg rest plate 13 can be stably hidden under the seat cushion 11.

[0051] When the leg rest plate 13 needs to be used, the seat cushion 11 is lifted. At this time, the baffle 111 is disengaged from the limit of the rotating shaft 132, the leg rest plate 13 is pulled out, the rotating shaft 132 slides along the sliding groove 140. After sliding in place, the rotating shaft 132 slides into the front end groove 1402, the leg rest plate 13 is rotated downward, the limit pin 131 and the clamping interface 1403 are clamped, the seat cushion 11 is lowered, and the baffle 111 abuts against the limit pin 131 at the limit opening 112 at the front end, thereby further improving the limiting effect on the leg rest plate 13.

[0052] In some embodiments, the seat cushion assembly 100 further includes a support structure 15. The support structure 15 is connected to the lower part of the seat cushion mounting frame 14 and supports the leg rest plate 13 when the leg rest plate 13 rotates to the lowest position.

[0053] In practice, the support structure 15 can be connected to the seat cushion mounting frame 14 by screws or the like. When the leg rest plate 13 is in the hidden state, the support structure 15 is located below the leg rest plate 13 and at one end away from the seat backrest 12. When the leg rest plate 13 is pulled out and rotated downward, the bottom surface of the leg rest plate 13 is supported by the support structure 15 near the seat cushion mounting frame 14, thereby further improving the stability of the leg rest plate 13. The width of the support structure 15 in the vehicle width direction is greater than or equal to the width of the leg rest plate 13, so as to support the position of the leg rest plate 13 in the entire width direction, so that the support structure 15 is uniformly stressed when supporting the leg rest plate 13 in the width direction.

[0054] In some embodiments, the support structure 15 includes a support plate 151 and a connecting plate 152. There are two connecting plates 152, which are respectively connected to both sides of the seat cushion mounting frame 14. The support plate 151 is connected between the two connecting plates 152 and has a distance from the seat cushion mounting frame 14 in the height direction. The support plate 151 supports the leg rest plate 13.

[0055] In practice, the two connecting plates 152 are respectively connected to both sides of the seat cushion mounting frame 14. The support plate 151 is located below the seat cushion mounting frame 14 and has a distance from the seat cushion mounting frame 14. By setting the support structure 15 as the support plate 151 and the connecting plate 152, the weight of the support structure 15 can be reduced, and at the same time, the leg rest plate 13 is mainly supported by the support plate 151; and the distance between the support plate 151 and the seat cushion mounting frame 14 can leave a certain rotation space for the leg rest plate 13 to be pulled out and rotated downward. While not interfering with the rotation of the leg rest plate 13, it can support the leg rest plate 13 after the leg rest plate 13 rotates in place.

[0056] In some embodiments, the seat cushion 11 and the seat cushion mounting frame 14 are rotatably connected through a seat cushion rotating shaft 16. When the seat cushion 11 is lifted, the rotation angle of the seat cushion 11 relative to the seat cushion mounting frame 14 is 35-50°.

[0057] In practice, if the seat cushion 11 is lifted, the rotation angle of the seat cushion 11 relative to the seat cushion mounting frame 14 is 40°. At this time, the baffles 111 on both sides of the seat cushion 11 can be disengaged from the rotating shaft 132, so that the rotating shaft 132 can slide out toward the front end of the seat 1 when the leg rest plate 13 is pulled. By limiting the lifting angle of the seat cushion 11 and the seat cushion mounting frame 14, it is not necessary to lift the seat cushion 11 significantly each time, so that after the leg rest plate 13 is pushed into the seat cushion mounting frame 14, the seat cushion 11 can be quickly lowered, saving manpower and being convenient to operate.

[0058] The embodiment of the present utility model also discloses a vehicle, which includes the above-mentioned seat cushion assembly 100. After the seat cushion 11 is lifted, the sliding out or pushing in of the leg rest plate 13 is manually controlled, with simple operation, low cost, and simple structure. Moreover, the leg rest plate 13 can be hidden under the seat cushion 11, making it convenient and comfortable for the occupant to use the leg rest plate 13 and improving the riding experience of the occupant.
