[0026] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] The definitions of up and down, front and back directions in the present invention are all defined with reference to the directions observed by the child when riding in the stroller. Specifically, the up and down directions in the present invention refer to Figure 2 The upper and lower directions in the present invention refer to the front and rear directions Figure 2 left and right direction in center.

[0028] Embodiment 1

[0029] like Figures 1 to 4As shown, the present invention provides a child stroller, comprising a stroller frame 10 having an unfolded position and a folded position, a front wheel assembly 20, and a rear wheel assembly 30, wherein the stroller frame 10 comprises: a front wheel bracket 100, a rear wheel bracket 200, a push rod bracket 300, and a seat bracket 400, the front wheel bracket 20 is arranged at the lower part of the front wheel bracket 100, and the front wheel bracket 100 comprises a first section connected to the front wheel assembly 20 and a second section bent from the end of the first section and extending upward; the rear wheel assembly 30 is arranged at the lower part of the rear wheel bracket 200, and the rear wheel bracket 200 and the front wheel bracket 10 are connected. 0 can be relatively slidably and relatively rotatably connected, specifically, a sliding member is provided on the rear wheel bracket 200, in this embodiment, the sliding member is a sliding sleeve 201, the sliding sleeve 201 is sleeved on the rear wheel bracket 200, the sliding sleeve 201 can slide along the axial direction of the rear wheel bracket 200, and the sliding sleeve 201 is pivotally connected to the front wheel bracket 100; the rear end of the seat bracket 400 is pivotally connected to the upper end of the second section of the front wheel bracket 100, and the front end of the seat bracket 400 is pivotally connected to the upper end of the rear wheel bracket 200; when the cart frame 10 is in the unfolded position, as shown Figures 1 to 2 As shown, the seat bracket 400 is parallel to the horizontal plane, the rotation connection between the front wheel bracket 100 and the seat bracket 400 is located behind the rotation connection between the rear wheel bracket 200 and the seat bracket 400, and a triangular structure is formed between the front wheel bracket 100, the rear wheel bracket 200 and the seat bracket 400. When the seat bracket 400 is subjected to downward pressure, due to the existence of the triangular structure, the sliding sleeve 201 cannot slide on the rear wheel bracket 200. Without setting a locking mechanism, the stability of the stroller frame 10 can be maintained, making the structure of the child stroller simpler; when the stroller frame 10 is in the folded state When the front wheel bracket 100 is in the forward position, the seat bracket 400 is located in front of the rear wheel bracket 200, the push rod bracket 300 is located behind the rear wheel bracket 200, and the rotation connection between the front wheel bracket 100 and the seat bracket 400 is located in front of the rotation connection between the rear wheel bracket 200 and the seat bracket 400; the push rod bracket 300 is connected to the seat bracket 400, specifically, the push rod bracket 300 extends obliquely from the upper rear to the lower front, and the lower end of the push rod bracket 300 is fixedly connected to the front end of the seat bracket 400 as a whole. In order to improve safety and avoid collision or puncture, the connection is a rounded transition connection.

[0030] To facilitate children to sit in the stroller, the stroller also includes a seat pocket (not shown in the figure), which is formed by a cloth cover and is connected to the seat bracket 400. At the same time, to enhance the safety of children when sitting, the two sides and the rear of the seat pocket are also connected to the push rod bracket 300 to support the child's back and prevent the child from falling from the left and right sides.

[0031] In order to further improve the comfort and safety of children when riding, the stroller frame 10 also includes a support rod 500 , which extends along the left-right direction of the stroller frame 10 and is fixedly connected to the rear end of the seat bracket 400 .

[0032] like Figure 4 As shown, when the stroller frame 10 is in the folded position, the lowest points of the front wheel assembly 20 and the rear wheel assembly 30 form a support plane for supporting the stroller frame 10, so that the stroller frame 10 can stand on its own.

[0033] In order to facilitate pushing the stroller and to facilitate exertion of force and gripping, the stroller also includes a push handle 600, which extends along the left and right directions of the stroller frame 10. In the present embodiment, the push handle 600 is rotatably connected to the upper end of the push rod bracket 300, and the rotational connection between the push handle 600 and the push rod bracket 300 has a position locking function. When the stroller frame 10 is in the unfolded position, the push handle 600 can be locked in the plane where the push rod bracket 300 is located.

[0034] The folding process of the cart frame 10 in this embodiment is described below.

[0035] When the stroller frame 10 is transformed from the unfolded position to the folded position, Figures 2 to 4 As shown, it is only necessary to lift the front end of the seat bracket 400 upwards so that the front wheel assembly 20 and the rear wheel assembly 30 are suspended in the air, and the sliding sleeve 201 can slide on the rear wheel bracket 200 to drive the push rod bracket 300 to flip backwards to be close to the rear wheel bracket 200. At the same time, the front wheel bracket 100 is driven to be close to the rear wheel bracket 200 through the triangular structure, so that the cart frame 10 is transformed to the folded position.

[0036] Embodiment 2

[0037] like Figure 5 As shown, the second embodiment is basically the same as the first embodiment, except that the push handle 600 in the second embodiment is fixedly connected to the push rod bracket 300 as a whole, and the lower end of the push rod bracket 300 is rotatably connected to the front end of the seat bracket 400. Of course, the rotational connection has a position locking function, and when the cart frame 10 is in the unfolded position, the push rod bracket 300 can be maintained in a state of tilting from the upper rear to the lower front.

[0038] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
