[0036] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0037] See also Figures 1-6 An outdoor stroller includes a stroller base 1 and a front enclosure unit 2 arranged at the front end of the stroller base 1, a rear enclosure unit 3 arranged at the rear end of the stroller base 1, a left enclosure unit 4 arranged at the left end of the stroller base 1, and a right enclosure unit 5 arranged at the right end of the stroller base 1. As one embodiment, the left enclosure unit 4 and the right enclosure unit 5 have the same structure.

[0038] Among them, the cart base 1 includes a foldable base body 11 and cross bars 12 arranged at the front and rear ends of the base body 11. Each cross bar 12 is fixed with at least one vertical rod 13. As one embodiment, corresponding vertical rods 13 are respectively fixed at the two end corners of each cross bar 12, so that corresponding vertical rods 13 are respectively arranged at the four end corners of the cart base 1. The cross bars 12 are arranged in a horizontal state, and the vertical rods 13 are arranged in a longitudinal state.

[0039] In this embodiment, the base body 11 includes two parts that rotate with each other, and the outer ends of the two parts are rotatably connected to the crossbar 12 or the vertical rod 13 respectively.

[0040] Corresponding to the base body 11, the left surround unit 4 and the right surround unit 5 can also be folded and folded or opened synchronously with the base body 11. The folding and opening referred to here are similar to the foldable carts in the prior art. The specific structure can refer to the existing design structure, such as the public patent document CN208036335U.

[0041] Of course, the cart base 1 is also provided with a handle 14 and several rollers 15. If the handle 14 is installed on the front unit 2, the handle 14 can be in a rotatable connection form or a fixed connection form; if corresponding rollers 15 are respectively provided at the four end corners of the cart base 1, they can be specifically provided at the two ends of the two cross bars 12.

[0042] This embodiment mainly provides a detailed explanation of the capacity expansion of the cart.

[0043] In this embodiment, the front enclosure unit 2, the rear enclosure unit 3, the left enclosure unit 4 and the right enclosure unit 5 respectively have a folded first state and an unfolded second state. The folded first state is as follows: Figure 1 As shown, the second state of the expansion is as follows Figure 3 As shown, as a further design, the left side unit 4 and the right side unit 5 can further have a third state of semi-expanded, such as Figure 2 shown.

[0044] In this embodiment, the front enclosure unit 2, the rear enclosure unit 3, the left enclosure unit 4, and the right enclosure unit 5 are respectively rotatably connected to the cart base 1 or rotatably connected to the corresponding upright poles 13 to enhance their stability during state transitions.

[0045] In this embodiment, corresponding first limiting members 6 are respectively connected to the front enclosure unit 2 and the rear enclosure unit 3. The first limiting members 6 may be flexible pull ropes or rigid rod-shaped components. The first limiting members 6 are used to limit the front enclosure unit 2 and the rear enclosure unit 3, including limiting the first state of folding and limiting the second state of unfolding.

[0046] Specifically, one end of the first limiting member 6 is connected to the front enclosure unit 2 and the rear enclosure unit 3, and the connection method can be a fixed connection method or a detachable fixed connection method. The other end (outer end) of the first limiting member 6 is a detachable connection method, and this end is used to be connected to the vertical pole 13 and the cart base 1. When the front enclosure unit 2 and the rear enclosure unit 3 are in the first folded state, the outer end of the first limiting member 6 is connected to the cart base 1 to limit the front enclosure unit 2 and the rear enclosure unit 3 in this state; when the front enclosure unit 2 and the rear enclosure unit 3 are in the second unfolded state, the outer end of the first limiting member 6 is connected to the vertical pole 13 to limit the front enclosure unit 2 and the rear enclosure unit 3 in this state.

[0047] There are many ways to connect the outer end of the first limiting member 6 with the vertical rod 13 and the cart base 1. For example, a pin is set on the vertical rod 13 and the cart base 1, and a ring that matches the pin is set on the outer end of the first limiting member 6. After the ring is put on the pin, it can play a positioning role; other methods including magnetic attraction, latches, and snap-fit parts are also applicable.

[0048] In this embodiment, a second stopper 7 is rotatably connected to the vertical rod 13. The second stopper 7 is provided with a movable slot 71. The left and right enclosure units 4 and 5 are each provided with a connecting pin (not shown) that cooperates with the movable slot 71. The connecting pin is freely movable within the movable slot 71. When the left and right enclosure units 4 and 5 are in the second, unfolded state, the connecting pin moves to the outermost end of the movable slot 71, and is restrained by the wall of the movable slot 71 for further movement, thereby restraining the left and right enclosure units 4 and 5 in the second, unfolded state. When the left and right enclosure units 4 and 5 are in the first, folded state, the second stopper 7 remains between the left and right enclosure units 4 and the vertical rod 13, and between the right and right enclosure units 5 and the vertical rod 13.

[0049] Furthermore, the middle portion of the movable groove 72 also includes an inner groove opening 72 for limiting the connecting pin, such as Figure 5 As shown, the inner groove opening 72 is connected to the movable groove 71, and a concave is formed on the wall of the movable groove 71 so that the connecting pin can be inserted therein. When the connecting pin is inserted into the inner groove opening 72, the left surrounding unit 4 and the right surrounding unit 5 are in the third state of semi-expanded, and at this time the left surrounding unit 4 and the right surrounding unit 5 are limited, as shown in FIG. Figure 2 shown.

[0050] Regarding the limiting of the left and right surround units 4, 5 in the first folded state, in this embodiment, a third limiting member 8 is provided on the vertical pole 13, and a connecting head (not shown in the figure) that cooperates with the third limiting member 8 is provided on the left and right surround units 4, 5. As one implementation method, the third limiting member 8 is rotatably provided on the vertical pole 13, and includes a recess 81 that cooperates with the connecting head. When the left and right surround units 4, 5 are in the first folded state, the third limiting member 8 is rotated, and the recess 81 is engaged with the connecting head to limit the left and right surround units 4, 5 in this state. Of course, the third limiting member 8 can also be rotatably provided on the left and right surround units 4, 5, and the connecting head is provided on the vertical pole 13.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
