Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1 - Figure 4 The utility model provides a technical solution: a seamless leg support structure of a car seat, comprising a seat cushion 100, a leg support mechanism 200 is arranged at the left end of the seat cushion 100, the leg support mechanism 200 does not affect sitting on the seat, and the use area of ​​the seat cushion 100 can be adjusted as needed, the legs of the user sitting down can be supported, the convenience and comfort of the entire car seat are increased, and the application range of the seat cushion 100 is improved, the leg support mechanism 200 comprises an arc-shaped support plate 201 located at the left end of the seat cushion 100, the arc-shaped support plate 201 is L-shaped as a whole, and the vertical end of the arc-shaped support plate 201 is convenient to extend to the left end of the seat cushion 100, and an adjusting member 206 for driving the arc-shaped support plate 201 to move is arranged at the bottom of the seat cushion 100, the adjusting member 206 is convenient for adjusting the angle of the arc-shaped support plate 201, and it is convenient to unfold or fold it, and the leg support mechanism 200 also includes a driving motor 205 installed on the lower surface of the seat cushion 100;

[0024] The adjusting component 206 includes a rotating shaft 2061 horizontally installed below the seat cushion 100, and two rotating gears 2062 are fixedly sleeved on the rotating shaft 2061. The rotating gears 2062 are engaged with the adjusting rod 2063 to conveniently drive the arc-shaped support plate 201 to move. An adjusting rod 2063 that is movable and passes through the vertical plate 202 and is fixed to the inner side of the arc-shaped support plate 201 is engaged below the rotating gear 2062. The two adjusting rods 2063 are symmetrically distributed to provide stable support for the arc-shaped support plate 201.

[0025] In this embodiment, preferably, the adjusting rod 2063 is provided with an annular tooth 2064 meshing with the rotating gear 2062, so that the meshing annular tooth 2064 can be moved as the rotating gear 2062 rotates. The lower surface of the seat cushion 100 is provided with a support plate 2065 sleeved on the rotating shaft 2061, which does not affect the rotation of the rotating shaft 2061, thereby increasing the stability of the rotating shaft 2061.

[0026] In this embodiment, preferably, a driving motor 205 is provided at the rear end of the rotating shaft 2061, and the driving motor 205 can drive the rotating shaft 2061 to rotate in place. A stabilizing seat 204 is provided between the middle position of the rotating shaft 2061 and the lower surface of the seat cushion 100, and a bearing is embedded between the rotating shaft 2061 and the stabilizing seat 204 to support the rotating shaft 2061 without affecting its rotation.

[0027] In this embodiment, preferably, two guide support rods 203 that movably penetrate the vertical plate 202 are vertically arranged on the inner side of the arc-shaped support plate 201. The guide support rods 203 do not affect the movement of the arc-shaped support plate 201, but can support the arc-shaped support plate 201 to increase the bearing strength of the arc-shaped support plate 201.

[0028] In summary, when the area of ​​the seat cushion 100 needs to be adjusted and the user's legs need to be supported, the drive motor 205 can be operated to drive the rotating shaft 2061 to rotate in place, and synchronously drive the rotating gear 2062 to rotate. The annular tooth 2064 meshing with it moves to the left as the rotating gear 2062 rotates, thereby driving the adjustment rod 2063 to move to the left, and driving the arc-shaped support plate 201 to move to the left synchronously, thereby adjusting the supporting position of the arc-shaped support plate 201 for the legs, thereby increasing the stability and comfort of the seat cushion 100. The position adjustment of the arc-shaped support plate 201 is convenient and quick, which reduces the trouble of manual operation and increases the practicality and applicability of the seat cushion 100.

[0029] Example 2

[0030] Reference Figure 5 , which is the second embodiment of the utility model, and this embodiment is different from the previous embodiment.

[0031] In this embodiment, preferably, a support member 300 is provided between the arc-shaped support plate 201 and the seat cushion 100. By providing the support member 300, the arc-shaped support plate 201 can be guided and supported when it is unfolded, the moving stability of the arc-shaped support plate 201 is increased, and the bearing strength and usage strength of the arc-shaped support plate 201 are increased. The support member 300 includes a longitudinal plate 301 longitudinally fixed to the upper surface of the seat cushion 100, and two transverse plates 302 are provided between the left side of the longitudinal plate 301 and the left end of the seat cushion 100. Guide frames 303 are provided on the front and rear surfaces of the transverse plates 302. The guide frame 303 is a rectangular frame, which is convenient for supporting a slider 304 to be located in a rectangular slide of the rectangular frame. A support slider 304 is slidably provided in the guide frame 303. The support slider 304 can be I-shaped when viewed from the side, and the sliding connection between the two will not be detached up and down. A connecting plate 305 is provided between the upper surface of the support slider 304 and the lower surface of the arc-shaped support plate 201.

[0032] In this embodiment, preferably, a seat back 101 is rotatably provided at the right end of the seat cushion 100, and a leather cover is provided on the seat back 101. Subsequently, a leather cover may also be provided on the seat cushion 100 and the leg support mechanism 200 to protect the two.

[0033] In summary, when the arc-shaped support plate 201 moves, it drives the connecting plate 305 and the supporting slider 304 to move in the rectangular slideway in the guide frame 303. The supporting slider 304 is slidingly connected to the guide frame 303, so that the arc-shaped support plate 201 will not be offset when moving, and the stability is increased. The supporting slider 304 and the connecting plate 305 support the arc-shaped support plate 201, thereby increasing the bearing strength and usage strength of the arc-shaped support plate 201.
