[0047] Please refer to Figures 1 to 9 , Figure 1 which is a perspective view of the baby carriage 1 according to an embodiment of the present invention, Figure 2 is Figure 1 a perspective view of the baby carriage 1 in Figure 3 after removing the seat 24, Figure 2 and is a side view of the baby carriage 1 in Figure 4 is Figure 2The perspective view of the stroller 1 in a semi-folded state Figure 5 is Figure 4 the side view of the stroller 1 in Figure 6 is Figure 2 the perspective view of the stroller 1 after being folded Figure 7 is Figure 6 the side view of the stroller 1 in Figure 8 is Figure 6 the perspective view of the stroller 1 from another perspective in Figure 9 is the sectional view of the sliding member 12 and the seat fixing base 14

[0048] As Figures 1 to 8 shown, the stroller 1 includes a frame 10, a sliding member 12, a seat fixing base 14, a folding operation mechanism 16, a locking mechanism 18, a first fixing member 20, a second fixing member 22, and a seat 24. 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

[0049] As Figures 1 to 8 shown, in this embodiment, the frame 10 includes a front link 100, a cross bar 102, a handle 104, a front foot 106, a rear foot 108, a rear link 110, and a linkage member 112. The front link 100 is pivotally connected to the front foot 106. The cross bar 102 is disposed on the handle 104. The linkage member 112 is pivotally connected to the handle 104. The front link 100, the linkage member 112, and the rear link 110 are pivotally connected to each other. The handle 104, the rear link 110, and the rear foot 108 are pivotally connected to each other. Therefore, the handle 104 can drive the front foot 106 and the rear foot 108 to fold or unfold through the front link 100, the rear link 110, and the linkage member 112

[0050] As Figures 1 to 8 shown, in this embodiment, the handle 104 may include an upper handle 1040, a first lower handle 1042, and a second lower handle 1044. The first lower handle 1042 and the second lower handle 1044 are respectively pivotally connected to the upper handle 1040, so that the upper handle 1040, the first lower handle 1042, and the second lower handle 1044 can pivot relative to each other to fold or unfold. The folding operation mechanism 16 may be disposed on the upper handle 1040, and the locking mechanism 18 may be disposed at the pivotal connection of the upper handle 1040 and the second lower handle 1044. The locking mechanism 18 is used to lock the upper handle 1040 and the second lower handle 1044. The folding operation mechanism 16 is used to drive the locking mechanism 18 to unlock the upper handle 1040 and the second lower handle 1044 to fold the stroller 1. In this embodiment, the linkage member 112 may be pivotally connected to the first lower handle 1042, and the cross bar 102 may be disposed on the second lower handle 1044

[0051] AsFigure 2 , Figure 4 As shown in Figure 9 , the cross bar 102 is disposed relative to the front link 100. The slider 12 is rotatably connected to the front link 100. The seat fixing base 14 is rotatably connected to the cross bar 102 and slidably connected to the slider 12. In this embodiment, the slider 12 is rotatably connected to the front link 100 by a first fixing member 20, and the seat fixing base 14 is rotatably connected to the cross bar 102 by a second fixing member 22. As shown in Figure 9 , the first fixing member 20 can be connected to one end of the slider 12, so that a first shaft hole 26 is formed between the first fixing member 20 and the slider 12. Therefore, the front link 100 can pass through the first shaft hole 26, so that the slider 12 is rotatably connected to the front link 100. In addition, the second fixing member 22 can be connected to one end of the seat fixing base 14, so that a second shaft hole 28 is formed between the second fixing member 22 and the seat fixing base 14. Therefore, the cross bar 102 can pass through the second shaft hole 28, so that the seat fixing base 14 is rotatably connected to the cross bar 102. In this embodiment, the bottom of the seat fixing base 14 may have a chute 140. The slider 12 can be disposed in the chute 140, so that the seat fixing base 14 is slidably connected to the slider 12.

[0052] As shown in Figures 2 to 8 , when the frame 10 is folded, the front link 100 and the cross bar 102 move relatively away from each other, so that the seat fixing base 14 slides downward relative to the slider 12 (that is, the seat fixing base 14 slides in the direction of the ground relative to the slider 12). As shown in Figure 1 and Figure 2 , the seat 24 is detachably disposed on the seat fixing base 14. When the seat 24 is disposed on the seat fixing base 14, the seat fixing base 14 will drive the seat 24 to slide downward, thereby reducing the overall height after the frame 10 is folded, which is beneficial to the storage or transportation of the stroller 1.

[0053] In another embodiment, the slider 12 can also be rotatably connected to the cross bar 102 or an element between the cross bar 102 and the front link 100, and the seat fixing base 14 can also be rotatably connected to the front link 100. When the frame 10 is folded, the front link 100 moves downward, and the cross bar 102 moves upward, so that the front link 100 and the cross bar 102 move relatively away from each other. At this time, the seat fixing base 14 slides upward relative to the slider 12, thereby reducing the overall height after the frame 10 is folded, which is beneficial to the storage or transportation of the stroller 1.

[0054] ​​​​​​​​​​Therefore, according to different applications, the slider 12 can be rotatably connected between the cross bar 102 and the front link 100, and the seat fixing base 14 can be rotatably connected to the cross bar 102 or the front link 100. When the frame 10 is folded, the front link 100 will move relatively away from the cross bar 102, causing the seat fixing base 14 to slide relative to the slider 12.

[0055] Therefore, according to the above technical solution, the stroller of the present invention has at least the following advantages and beneficial effects: When the frame of the stroller of the present invention is folded, the front link will move relatively away from the cross bar, causing the seat fixing base to slide relative to the slider. When a seat is provided on the seat fixing base, the seat fixing base will drive the seat to slide, thereby reducing the overall height after the frame is folded, which is beneficial for the storage or transportation of the stroller.

[0056] 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 modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
