[0025] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, this embodiment provides a crank-slider seat leg rest, including a mounting support 100 and a multi-link telescopic structure 200. The multi-link telescopic structure 200 includes a drive member 210, a drive shaft 220, a drive slide plate 230, and a leg support plate 240. The drive member 210 is mounted on the mounting support 100, and the drive shaft 220 is rotatably mounted on the mounting support 100. The output end of the drive member 210 is connected to the drive shaft 220, and the drive slide plate 230 is fixedly mounted on the drive shaft 220. The leg support plate 240 is slidably disposed on the drive slide plate 230, and a linkage rod 250 is pivotally connected to one end of the leg support plate 240 near the drive shaft 220. The other end of the linkage rod 250 is pivotally connected to the mounting support 100.

[0027] Specifically, during use, the drive unit 210 starts working, which can drive the drive shaft 220 to rotate relative to the mounting bracket 100. When the drive shaft 220 rotates, it can drive the drive slide plate 230 on it to swing up and down. When the drive slide plate 230 swings, it can synchronously drive the leg support plate 240 to swing up and down, and at the same time, it can allow the drive slide plate 230 to slide on the leg support plate 240. Thus, the drive slide plate 230, the leg support plate 240, the linkage rod 250 and the mounting bracket 100 form a crank-slider structure, which allows the leg support plate 240 to extend forward when it is raised, or to retract inward when it is lowered. Through this setting, the storage length of the leg rest can be shortened, the space occupied by the seat leg rest can be reduced, and a multi-link structure can be eliminated, simplifying the structure.

[0028] The mounting support 100 has a pivot seat 110 for connecting the linkage rod 250. The pivot points of the linkage rod and the drive shaft 220 on the mounting support 100 are offset, so that the drive slide plate 230, the leg support plate 240, the linkage rod 250 and the pivot seat 110 of the mounting support 100 can form a crank-slider structure.

[0029] The leg support plate 240 is equipped with a leg support plate 300, which can support the sponge and other structures.

[0030] See Figures 1-10 As shown, in the optional embodiment, the drive slide plate 230 is provided with a guide groove 231, and the leg support plate 240 is provided with a guide slide 260.

[0031] Specifically, a guide groove 231 is provided on the drive slide plate 230, and a guide slide 260 is provided on the leg support plate 240, so that the drive slide plate 230 and the leg support plate 240 can slide smoothly relative to each other.

[0032] See Figures 1-10 As shown, in an optional embodiment, the guide slide 260 includes a first slide plate 261 and a second slide plate 262. The width of both the first slide plate 261 and the second slide plate 262 is greater than the width of the guide groove 231. A spacer support block 263 is provided on the first slide plate 261. The top of the spacer support block 263 can abut against the second slide plate 262, and the outer side of the spacer support block 263 can slide in contact with the guide groove 231. The first slide plate 261 and the second slide plate 262 are connected to each other.

[0033] Specifically, during installation, the first slide plate 261 and the second slide plate 262 are located on the upper and lower sides of the drive slide plate 230, respectively. The first slide plate 261 and the second slide plate 262 are fixed to the leg support plate 240 by bolts, and the drive slide plate 230 is located between the first slide plate 261 and the second slide plate 262, so that the drive slide plate 230 and the leg support plate 240 are stably connected together, and the drive slide plate 230 and the leg support plate 240 can slide relative to each other.

[0034] See Figures 1-10 As shown, in the optional embodiment, the driving component 210 includes a driving motor 211, a driving screw 212, and a driving mounting base 213; the output end of the driving motor 211 is provided with a conversion seat 214, which is slidably inserted into the driving mounting base 213, and the driving mounting base 213 is fixedly mounted on the mounting support 100; the driving screw 212 is inserted into the conversion seat 214, and the driving mounting base 213 has an oblong groove 215 for the driving screw 212 to pass through, so that the driving screw 212 can rotate relative to the driving mounting base 213; one end of the driving screw 212 is connected to the driving shaft 220.

[0035] Specifically, when the drive motor 211 is working, it can move the drive screw 212. When the drive screw 212 moves toward the drive shaft 220, it can drive the drive shaft 220 to rotate. The rotation of the drive shaft 220 can drive the drive slide plate 230 to swing upward. Then the drive slide plate 230 drives the leg support plate 240 to swing upward. Under the action of the pivot seat 110 and the linkage rod 250, the leg support plate 240 moves forward relative to the drive slide plate 230, thereby realizing the unfolding of the leg support plate 240 and the drive slide plate 230.

[0036] When the drive motor 211 drives the drive screw 212 to move, one end of the drive screw 212 swings with the drive slide plate 230, which can drive the drive motor 211 and the conversion seat 214 to rotate relative to the drive mounting seat 213, and the drive screw 212 can swing in the waist-shaped groove 215 of the drive mounting seat 213.

[0037] See Figures 1-10 As shown, in an optional embodiment, a quick-release assembly 400 is provided on the mounting support 100. The quick-release assembly 400 includes a quick-release mounting base 410 and a quick-release connecting plate 420.

A return spring 430 is provided between the quick-release mounting base 410 and the quick-release connecting plate 420. The quick-release connecting plate 420 has a quick-release locking tongue 421.

[0038] Specifically, the quick-release mounting base 410 is fixedly mounted on the mounting bracket 100, and the quick-release connecting plate 420 is slidably mounted on the quick-release mounting base 410. The user can pull the quick-release connecting plate 420 to move, so that the quick-release locking tongue 421 on the quick-release connecting plate 420 can be connected or separated from the quick-release lock cylinder on the car seat, thereby allowing for quick installation or removal of the seat leg rest.

[0039] See Figures 1-10 As shown, in an optional embodiment, the quick-release connecting plate 420 has an unlocking handle 422 that is easy for the user to operate.

[0040] Specifically, an unlocking handle 422 is provided at the end of the quick-release connecting plate 420. Users can pull the unlocking handle 422 to move the quick-release connecting plate 420, thereby completing the unlocking operation.

[0041] See Figures 1-10 As shown, in the optional embodiment, the quick-release mounting base 410 is provided with a positioning pin 423.

[0042] Specifically, a positioning pin 423 is provided on the quick-release mounting base 410 to facilitate blind installation by the user.

[0043] This embodiment provides a car seat, including a crank slider seat leg rest.
