[0050] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0051] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, this embodiment provides an electric seamless leg rest adjustment device, including a flip component 100, a leg rest bracket 200 and a leg rest sponge seat cover assembly 300; a first shielding plate 110 is provided on the flip component 100, the flip component 100 is arranged at the bottom of the seat basin 400, a second shielding plate 250 is provided on the leg rest bracket 200, and the leg rest sponge seat cover assembly 300 is arranged on the seat basin 400 and the leg rest bracket 200.

[0052] Specifically, when the leg rest is flipped, the flip assembly 100 drives the leg rest bracket 200 to swing, thereby driving the leg rest sponge seat cover assembly 300 to unfold, and when the flip assembly 100 and the leg rest bracket 200 are unfolded, the first shielding panel 110 provided on the flip assembly 100 and the second shielding panel 250 provided on the leg rest bracket 200 can be synchronously unfolded to shield the space under the flip assembly 100 and the leg rest bracket 200, and when the flip assembly 100 drives the leg rest sponge seat cover assembly 300 to shrink, the first shielding panel 110 and the second shielding panel 250 will be synchronously flipped and shrunk, thereby reducing the occupation of the space at the bottom of the seat basin 400.

[0053] See also Figure 1 - Fig.11 As shown, in an optional scheme of the present embodiment, the flip assembly 100 includes a fixed plate 120, an intermediate plate 130, a first rod 140, a second rod 150 and a third rod 160; the fixed plate 120 is arranged at the bottom of the seat basin 400, one end of the fixed plate 120 is pivoted to one end of the intermediate plate 130, the other end of the fixed plate 120 is pivoted to the first rod 140, and the end of the first rod 140 away from the fixed plate 120 is pivoted to the second rod 150; the middle part of the second rod 150 is pivoted to the middle part of the intermediate plate 130, and the end of the second rod 150 away from the first rod 140 is pivoted to the leg support bracket 200; the end of the intermediate plate 130 away from the fixed plate 120 is connected to the leg support bracket 200 through the third rod 160, and both the intermediate plate 130 and the leg support bracket 200 are pivoted to the third rod 160.

[0054] Among them, the flip assembly 100 also includes a first power member 170, which is arranged on the fixed plate 120, and a transmission rod 180 is arranged between the two middle plates 130. The first power member 170 is connected to the transmission rod 180 so that the first power member 170 can drive the middle plate 130 to swing; the transmission rod 180 is located between the fixed plate 120 and the second rod 150.

[0055] Among them, the first shielding plate 110 includes an inner shielding plate 111 and an outer shielding plate 112; the inner shielding plate 111 is fixedly set on the outer wall of the middle plate 130, and the outer shielding plate 112 is rotatably set on the inner shielding plate 111, and a reset torsion spring 113 is set between the outer shielding plate 112 and the inner shielding plate 111.

[0056] A guide rail 114 is provided on the inner shielding plate 111 , and a slide groove adapted to the guide rail 114 is provided on the outer shielding plate 112 .

[0057] The second shielding plate 250 includes a shielding buckle plate 251 and a shielding linkage plate 252; the shielding linkage plate 252 is fixed to the leg support bracket 200, and the shielding linkage plate 252 can abut against the outer shielding plate 112 when the leg support bracket 200 swings and contracts; the shielding buckle plate 251 is clamped on the outer wall of the shielding linkage plate 252. The shielding linkage plate 252 is provided with an abutting groove 253 abutting against the outer shielding plate 112.

[0058] Among them, a U-shaped front support plate 210 is arranged on the leg support bracket 200, a slide rail 201 is arranged on the leg support bracket 200, and the U-shaped front support plate 210 is slidably arranged on the slide rail 201; one end of the leg support sponge seat cover assembly 300 is arranged at the bottom of the U-shaped front support plate 210; and a third shielding plate 220 is arranged on both sides of the U-shaped front support plate 210.

[0059] Among them, a second power member 230 is provided on the leg support bracket 200 , and the second power member 230 is connected to the U-shaped front support plate 210 .

[0060] Among them, a tank chain 240 is arranged at the bottom of the leg support sponge seat cover assembly 300, and the tank chain 240 is fixed on the U-shaped front support plate 210.

[0061] See also Figure 1 - Fig.11As shown, specifically, when the leg support sponge seat cover assembly 300 is retracted, the first power member 170 works to drive the transmission rod 180 to swing, and the transmission rod 180 can drive the middle plate 130 to swing relative to the fixed plate 120. When the middle plate 130 swings, it can drive the second rod 150 and the third rod 160 to swing, and the third rod 160 can pull the front end of the leg support bracket 200 to lift up. Because the transmission rod 180 is located below the second rod 150, the end of the second rod 150 close to the first rod 140 cannot drop when the middle plate 130 swings. Therefore, when the middle plate 130 swings, the end of the second rod 150 close to the first rod 140 is lifted, and the first rod 140 is lifted synchronously, so that the middle plate 130 swings close to the fixed plate 120, and the leg support bracket 200 is pulled close to the middle plate 130 by the second rod 150 and the third rod 160, so that the fixed plate 120, the middle plate 130 and the leg support bracket 200 are folded together to reduce the space occupied by the leg support. Moreover, during the contraction process, the third shielding plates 220 on both sides of the U-shaped front support plate 210 can move with the U-shaped front support plate 210, and the third shielding plates 220 can abut against the leg support sponge seat cover assembly 300, so that the internal structure is shielded by the third shielding plates 220. In addition, the shielding linkage plate 252 of the second shielding plate 250 is installed on the leg support bracket 200, and the shielding buckle plate 251 is buckled on the shielding linkage plate 252. When the second rod 150 and the third rod 160 drive the leg support bracket 200 to swing, The swing of the leg rest bracket 200 drives the shielding linkage plate 252 to swing synchronously. When the shielding linkage plate 252 swings, it can abut against the outer shielding plate 112 of the first shielding plate 110, thereby driving the outer shielding plate 112 to compress the reset torsion spring 113. The outer shielding plate 112 can swing and overlap with the inner shielding plate 111, so that the outer shielding plate 112 will not interfere with the components on the leg rest bracket 200 (when the leg rest is unfolded, the outer shielding plate 112 can be unfolded under the action of the reset torsion spring 113, thereby shielding the internal structure).

[0062] In addition, when the leg rest contracts, the second power part 230 on the leg rest bracket 200 can drive the U-shaped front support plate 210 to retract, and a tank chain 240 is provided on the U-shaped front support plate 210, and the leg rest sponge seat cover assembly 300 is connected to the U-shaped front support plate 210 through the tank chain 240. When the leg rest contracts, the leg rest sponge seat cover assembly 300 located at the tank chain 240 will contract into an S shape, thereby realizing the contraction of the leg rest sponge seat cover assembly 300.

[0063] Among them, a face cover fixing steel wire 260 is provided on the leg support bracket 200, and one end of the face cover is connected to the face cover fixing steel wire 260. During the extension and retraction process of the leg support, the face cover fixing steel wire 260 moves synchronously with the leg support bracket 200, so that the face cover is always in a taut state.

[0064] This embodiment provides a car seat, including an electric seamless leg support adjustment device.

[0065] Specifically, the car seat provided in this embodiment has the advantages of the above-mentioned electric seamless leg support adjustment device compared with the prior art, which will not be described in detail here.
