[0066] Please refer to Figures 1 to 6 , Figure 1 is a perspective view of the stroller 1 according to an embodiment of the present invention, Figure 2 is Figure 1 a perspective view of the seat 12 in Figure 3 is Figure 2 a side view of the seat 12 in Figure 4 is Figure 3 a side view after the first backrest support 122 in Figure 5 is Figure 4 a side view after the second backrest support 124 in Figure 6 is Figure 5 a side view after the seat 12 is folded in

[0067] As Figure 1 shown, the stroller 1 includes a frame 10 and a seat 12, wherein the seat 12 is detachably disposed on the frame 10. As Figures 2 to 6 shown, the seat 12 includes a seat board 120, a first backrest support 122, a second backrest support 124, a third backrest support 126, a first sliding sleeve 128, a second sliding sleeve 130, a backrest link 132, an armrest 134, an armrest fixing seat 136, an armrest link 138, and a canopy 140. It should be noted that the stroller 1 of the present invention is generally a left-right symmetric structure. Therefore, some of the components described in the present invention are provided on both sides of the stroller 1.

[0068] As Figures 2 to 6As shown, the second backrest support member 124 is telescopically connected to the first backrest support member 122, and the third backrest support member 126 is telescopically connected to the second backrest support member 124 and pivotally connected to the seat plate 120. Therefore, the first backrest support member 122, the second backrest support member 124, and the third backrest support member 126 can slide relative to each other to be folded or unfolded, and the third backrest support member 126 can rotate relative to the seat plate 120 to be folded or unfolded. The first sliding sleeve 128 is disposed on the first backrest support member 122, and the second sliding sleeve 130 is disposed on the second backrest support member 124. Therefore, the first sliding sleeve 128 will slide as the first backrest support member 122 slides, and the second sliding sleeve 130 will slide as the second backrest support member 124 slides.

[0069] As Figures 2 to 6 shown, the backrest link 132 is pivotally connected to the seat plate 120 and the second sliding sleeve 130. Therefore, when the second backrest support member 124 slides relative to the third backrest support member 126, the second sliding sleeve 130 will drive the backrest link 132 to rotate, thereby driving the third backrest support member 126 to rotate relative to the seat plate 120. In addition, the armrest 134 is detachably connected to the armrest fixing seat 136, the armrest fixing seat 136 is pivotally connected to the second sliding sleeve 130, and the armrest link 138 is pivotally connected to the armrest fixing seat 136 and the backrest link 132. Therefore, when the second sliding sleeve 130 drives the backrest link 132 to rotate, the backrest link 132 will also drive the armrest link 138 to rotate, thereby driving the armrest fixing seat 136 and the armrest 134 thereon to rotate. Furthermore, the awning 140 is pivotally connected to the first sliding sleeve 128. Therefore, the awning 140 will slide as the first sliding sleeve 128 slides, and the awning 140 can rotate relative to the first backrest support member 122.

[0070] As Figures 3 to 6 shown, when the first backrest support member 122, the second backrest support member 124, and the third backrest support member 126 slide relative to each other to be folded or unfolded, the second sliding sleeve 130 can drive the third backrest support member 126 to be folded or unfolded relative to the seat plate 120 through the backrest link 132, so that the seat 12 is folded or unfolded as a whole. At the same time, the second sliding sleeve 130 can also drive the armrest 134 to be folded or unfolded synchronously through the backrest link 132 and the armrest link 138. Furthermore, the awning 140 will also slide as the first sliding sleeve 128 slides, and the user can rotate the awning 140 to fold or unfold the awning 140. Thereby, the user can conveniently and quickly fold or unfold the seat 12. The present invention achieves a three-stage folding through the telescopic arrangement of the first backrest support member 122, the second backrest support member 124, and the third backrest support member 126. Thereby, the overall height of the seat 12 can be effectively reduced after being folded, as Figure 6 shown.

[0071] Please refer to Figure 7 ,Figure 7 Yes Figure 6 Side view of the seat 12 equipped with the backrest structure 142. As Figure 7 shown, the seat 12 may further include a backrest structure 142, wherein the backrest structure 142 may include a first plate body 1420 and a second plate body 1422 pivotally connected to each other. In practical applications, the backrest structure 142 is used for the seat cloth to be sleeved thereon.

[0072] Please refer to Figure 8 and Figure 9 , Figure 8 Yes Figure 2 Partial cross-sectional view of the seat 12 in Figure 9 Yes Figure 8 Combined three-dimensional view of the first engaging member 148, the second engaging member 152 and the driving member 154 in

[0073] As Figure 8 shown, the seat 12 further includes an operating member 144, a first fixing seat 146, a first engaging member 148, a second fixing seat 150, a second engaging member 152, a driving member 154, a traction member 156, a first elastic member 158 and a second elastic member 160. The operating member 144 is disposed on the first backrest support member 122. The first fixing seat 146 is disposed in the second backrest support member 124 and close to the first backrest support member 122. The first engaging member 148 is movably disposed on the first fixing seat 146. The second fixing seat 150 is disposed in the second backrest support member 124 and close to the third backrest support member 126. The second engaging member 152 is movably disposed on the second fixing seat 150. The driving member 154 is movably disposed in the second backrest support member 124. The traction member 156 is connected to the operating member 144 and the driving member 154. In this embodiment, the traction member 156 may be a steel wire, but is not limited thereto. Two ends of the first elastic member 158 respectively abut against the first fixing seat 146 and the driving member 154. Two ends of the second elastic member 160 respectively abut against the second fixing seat 150 and the driving member 154. In this embodiment, the first elastic member 158 and the second elastic member 160 may be springs, but are not limited thereto.

[0074] As Figure 8As shown, the first backrest support member 122 has a first engaging hole 1220, and the third backrest support member 126 has a second engaging hole 1260. When the first backrest support member 122 is unfolded relative to the second backrest support member 124, the first engaging member 148 engages with the first engaging hole 1220 to limit the sliding of the first backrest support member 122 relative to the second backrest support member 124. When the second backrest support member 124 is unfolded relative to the third backrest support member 126, the second engaging member 152 engages with the second engaging hole 1260 to limit the sliding of the second backrest support member 124 relative to the third backrest support member 126. The user can operate the operating member 144 to pull the traction member 156. In this embodiment, the operating member 144 can be a handle pivotally connected to the first backrest support member 122. Therefore, the user can press this handle to pull the traction member 156. When the operating member 144 pulls the traction member 156, the traction member 156 will pull the driving member 154 in the direction of arrow A1. At this time, the driving member 154 will drive the first engaging member 148 and the second engaging member 152 to move in the direction of arrow A2 and disengage from the first engaging hole 1220 and the second engaging hole 1260, so that the first backrest support member 122, the second backrest support member 124, and the third backrest support member 126 can slide relative to each other and fold up.

[0075] As Figure 9 shown, the first engaging member 148 may have a first driving portion 1480, the second engaging member 152 may have a second driving portion 1520, and the driving member 154 may have a first inclined slot 1540 and a second inclined slot 1542. The first driving portion 1480 of the first engaging member 148 is disposed in the first inclined slot 1540 of the driving member 154, and the second driving portion 1520 of the second engaging member 152 is disposed in the second inclined slot 1542 of the driving member 154. As Figure 8 and Figure 9 shown, when the traction member 156 pulls the driving member 154 in the direction of arrow A1, the first inclined slot 1540 will push the first driving portion 1480 to move in the direction of arrow A2 to drive the first engaging member 148 to disengage from the first engaging hole 1220, and the second inclined slot 1542 will push the second driving portion 1520 to move in the direction of arrow A2 to drive the second engaging member 152 to disengage from the second engaging hole 1260. As Figure 8 shown, when the traction member 156 pulls the driving member 154 in the direction of arrow A1, the driving member 154 will compress the first elastic member 158 and the second elastic member 160. When the user releases the operating member 144, the elastic forces generated by the first elastic member 158 and the second elastic member 160 will push the driving member 154 in the opposite direction of arrow A1 to reset the driving member 154.

[0076] Please refer to Figures 10 to 12 , Figure 10 is Figure 2Stereogram after the calf support 162 of the seat 12 in Figure 11 is Figure 2 Partial enlarged view of the seat 12 in Figure 12 is Figure 11 Partial sectional view of the seat 12 in

[0077] As Figures 10 to 12 shown, the seat 12 may further include a calf support 162, and the front end of the seat board 120 may have a receiving groove 1200, wherein the calf support 162 is movably disposed in the receiving groove 1200. In this embodiment, a limiting portion 1202 is provided at the opening of the receiving groove 1200. As Figure 11 and Figure 12 shown, when the calf support 162 is completely received in the receiving groove 1200, the limiting portion 1202 restricts the movement of the calf support 162 to prevent the calf support 162 from detaching from the receiving groove 1200. Therefore, the user can pull out the calf support 162 from the seat 12 for use, or can receive the calf support 162 in the receiving groove 1200 of the seat 12.

[0078] Therefore, according to the above technical solutions, the seat and the stroller of the present invention at least have the following advantages and beneficial effects: The present invention achieves three-stage folding by the telescopic settings of the first backrest support member, the second backrest support member, and the third backrest support member. Thereby, the overall height can be effectively reduced after the seat is folded. In addition, when the first backrest support member, the second backrest support member, and the third backrest support member slide relative to each other to fold or unfold, the second sliding sleeve can drive the third backrest support member to fold or unfold relative to the seat board through the backrest link, so that the whole seat folds or unfolds. At the same time, the second sliding sleeve can also drive the armrest to fold or unfold synchronously through the backrest link and the armrest link. Furthermore, the canopy will also slide as the first sliding sleeve slides, and the user can rotate the canopy to fold or unfold the canopy. Thereby, the user can conveniently and quickly fold or unfold the seat.

[0079] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
