[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0027] Referring to Figure 1 , Figure 2 and Figure 3 as shown, wherein, Figure 1 is a schematic structural diagram of a specific embodiment of the present invention, Figure 2 is a schematic structural diagram of the third main frame 8 in the embodiment of the present invention, Figure 3 is a schematic structural diagram of the lever-type quick clamping member 9 in the embodiment of the present invention.

[0028] A portable bicycle child seat includes a main body and a seat board 1. Among them, the main body includes a first main frame 2 and a second main frame 3. The first main frame 2 and the second main frame 3 are cross-rotationally connected, and in this embodiment, the rotation connection points of the first main frame 2 and the second main frame 3 are all in the middle thereof.

[0029] A first clamping portion 4 for the bicycle triangular frame to be inserted and clamped is fixedly arranged at the bottom end of the first main frame 2, and a second clamping portion 5 is fixedly arranged at the bottom end of the second main frame 3. In addition, a limiting portion for limiting the rotation separation angle between the first main frame 2 and the second main frame 3 is arranged on the second main frame 3. The limiting portion includes a limiting rod 6, and the limiting rod 6 is located on the rotation path of the first main frame 2. It should be noted that the first clamping portion 4 and the second clamping portion 5 are on the same plane.

[0030] One side of the seat board 1 is rotatably connected to the first main frame 2. There are also two sets of roller groups 7, which are respectively arranged at the bottom ends of the first main frame 2 and the second main frame 3.

[0031] It should be noted that in this embodiment, the rotational connection between the first main frame 2 and the second main frame 3 enables this product to present a highly practical function of being foldable and storable. When folding, only the first main frame 2 and the second main frame 3 need to be directly rotated; when this product needs to be installed on a bicycle for use, only the first main frame 2 and the second main frame 3 need to be rotated and unfolded. When the limiting rod 6 abuts against the first main frame 2, the limiting rod 6 restricts the unfolding angle of the main body, and then the first clamping part 4 and the second clamping part 5 can be clamped on the triangular frame of the bicycle. It has the advantages of strong clamping versatility and being convenient for daily carrying.

[0032] It should be noted that in this embodiment, one side of the seat board 1 is set in an adjustable manner that can be flipped up and down with the first main frame 2. When not in use, the seat board 1 can be flipped up to change to a storage state, and when in use, only the seat board 1 needs to be flipped down. During the process of flipping down the seat board 1, one side of the seat board 1 will gradually approach the second main frame 3. When one side of the seat board 1 abuts against the second main frame 3, the seat board 1 is in a state ready for use.

[0033] More preferably, in this embodiment, there is also a third main frame 8. The third main frame 8 passes through the first main frame 2, and the first main frame 2 is fixedly provided with a lever-type quick clamping member 9 for clamping the third main frame 8; one end of the third main frame 8 away from the first main frame 2 is provided with a third clamping part 10. The first clamping part 4, the second clamping part 5, and the third clamping part 10 are all in the same plane. In this embodiment, the lever-type quick clamping member 9 is a commonly used clamping component on a bicycle, such as the clamping member for adjusting the height of the saddle, which will not be elaborated here.

[0034] It should be noted that the setting of the third main frame 8 enables this product to add a positioning component, which can not only further improve the stability effect, but also play a role in improving the adaptability of this product when encountering a bicycle with a relatively large triangular frame. By adjusting the length of the third main frame 8, and then clamping the third clamping part 10 on the third triangular frame of the bicycle.

[0035] More preferably, in order to improve the riding stability of this product, in this embodiment, one side of the seat board 1 is provided with a positioning groove 11 for the second main frame 3 to be inserted into and limit the further downward flipping of the seat board 1 when the seat board 1 is flipped to the use state. Therefore, during riding, the second main frame 3 can not only bear the weight of the seat board 1, but also achieve a positioning effect.

[0036] For further refinement, in this embodiment, a self-locking hinge (not shown in the figure) that restricts the rotation of the seat plate 1 is provided at the rotational connection between the seat plate 1 and the first main frame 2. It should be noted that the self-locking hinge is a commonly used limit locking component in daily life. In this embodiment, it locks the unfolded and folded states of the seat plate 1, playing a role in positioning and locking the seat plate 1, and will not be elaborated further here.

[0037] More preferably, in this embodiment, the limiting part further includes a fixing member 12. The fixing member 12 is fixed to the second main frame 3, and a plurality of adjustment holes 13 for the limiting rod 6 to pass through are provided on the fixing member 12. Such an adjustable setting enables the rotational unfolding angle of the main body to be adjusted according to actual needs, further improving the flexibility and practicality of this product. Further, the adjustment holes 13 can be linearly evenly distributed in a direction away from the second main frame 3 or distributed in the length direction parallel to the second main frame 2. In this embodiment, the adjustment holes 13 are linearly evenly distributed in a direction away from the second main frame 3.

[0038] More preferably, a receiving groove 14 for inserting and receiving one end of the third main frame 8 is provided at the top of the second main frame 3. Handles 15 are provided at the tops of both the first main frame 2 and the second main frame 3. The roller group 7 includes universal wheels.

[0039] It should be noted that this product can also be used as a trolley. At this time, the third main frame 8 can be inserted and received in the receiving groove 14, and the setting of the handle also facilitates the pushing of this product.

[0040] As an improvement to the above solution, the first clamping part 4, the second clamping part 5, and the third clamping part 10 are all clamping members 16. The clamping member 16 is provided with a clamping groove 17, and the clamping groove 17 is arranged to gradually contract from the groove opening to the groove bottom. The contracting setting enables this product to be applicable to many bicycles on the market, and can improve the flexibility and practicality of this product.

[0041] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
