[0025] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the embodiments and the accompanying drawings.
[0026] See also Figure 1The bicycle system 1000 of the utility model comprises a child seat mechanism 100 and a bicycle 200. Optionally, Figure 1 In the embodiment, as an example, the bicycle 200 is a foldable bicycle, which is convenient for carrying when going out and reduces the space occupied. Obviously, according to actual needs, the bicycle 200 can also be made into a non-foldable bicycle. Figure 1 Meanwhile, the bicycle 200 comprises a frame 210 and a front wheel 220, a rear wheel 230 and a seat post 240 mounted on the frame 210. Optionally, Figure 1 As an example, the seat post 240 is equipped with a main seat cushion 250 which is higher than the child seat cushion 20 (described below) to prevent the child sitting on the child seat cushion 20 from blocking the field of vision of the user sitting on the main seat cushion 250. It should be noted that since the specific structures of the seat 240, the front wheel 220 and the rear wheel 230 respectively assembled with the frame 210 are well known in the art, they will not be described in detail here.
[0027] Recombination Figure 2 The child seat mechanism 100 includes a load-bearing frame 10 and a child seat cushion 20. The load-bearing frame 10 has a front end 11 and a rear end 12 for assembly and connection with the bicycle 200. The load-bearing frame 10 extends a connection bracket 30 for assembly and connection with the child seat cushion 20 upwardly at a position between the front end 11 and the rear end 12, so that the load-bearing frame 10 provides a load-bearing support for the child seat cushion 20 through the connection bracket 30. The front end 11 of the load-bearing frame 10 is provided with a clamp groove 13 that penetrates the front end 11 forward, backward and downward, and the clamp groove 13 separates the front end 11 of the load-bearing frame 10 into a first side arm 111 and a second side arm 112. The front end 11 of the load-bearing frame 10 is clamped on the cross beam 211 of the frame 210 from above by means of the clamp groove 13, and the cross beam 211 provides support for the load-bearing frame 10 from below; and the first side arm 111 and the second side arm 112 also clamp the cross beam 211 together to ensure a stable installation and prevent the front end 11 of the load-bearing frame 10 from accidentally falling off from the cross beam 211. The rear end 12 of the load-bearing frame 10 is assembled and connected to the seat rod 240, and the seat rod 240 provides support for the rear end 12 of the load-bearing frame 10. Specifically, Figure 1As an example, the load-bearing frame 10 has an arc-shaped curved section 14 and a straight section 15 at a position between the front end 11 and the rear end 12 thereof. The arc-shaped curved section 14 is connected to the front end 11 of the load-bearing frame 10 forward, and the arc-shaped curved section 14 passes over the connecting bracket 30 backward, and the straight section 15 is connected to the arc-shaped curved section 14 and the rear end 12 of the load-bearing frame 10 respectively; such a design is that the gravity acting on the child seat cushion 20 is mainly borne by the arc-shaped curved section 14, while the straight section 15 only shares part of the gravity, thereby effectively increasing the load-bearing capacity of the load-bearing frame 10, and thus better meeting the riding needs of children. More specifically, as follows:
[0028] like Figures 2 to 4 As shown, as an example, the child seat mechanism 100 further includes a protective rubber pad 40 located in the clamp groove 13, and the protective rubber pad 40 is respectively in close contact with the first side arm 111 and the second side arm 112; with the help of the protective rubber pad 40, the scratches and damages to the cross beam 211 of the frame 210 are effectively avoided, thereby extending the service life of the bicycle 200, and the shock absorption effect between the front end 11 of the load-bearing frame 10 and the cross beam 211 of the frame 210 can be appropriately increased. Specifically, Figure 4 As an example, the clamp groove 13 and the protective rubber pad 40 are both in an inverted "U" shape to better match the profile of the crossbeam 211 of the frame 210, so that the front end 11 of the load-bearing frame 10 is better in close contact with the crossbeam 211 of the frame 210; Obviously, according to actual needs, the shapes of the clamp groove 13 and the protective rubber pad 40 can also be other shapes, so it is not used in this example. Figure 4 Limits shown.
[0029] like Figures 1 to 5 As shown in FIG. 1 , as an example, a footrest structure 50 is provided on the first side arm 111 and the second side arm 112 and is arranged along the left and right directions of the load-bearing frame 10 . The footrest structure 50 is located outside the clamp groove 13 . With the help of the footrest structure 50 , it is convenient for children to place their feet, thereby improving the comfort of children. Figure 1 and Figure 3 As an example, the footrest structure 50 includes a hollow cylinder 51 and a locking screw 52 inserted into the cylinder 51. The locking screw 52 also passes through the cylinder 51 and is threadedly connected to the corresponding first side arm 111 or second side arm 112. This simplifies the structure of the footrest structure 50 on the one hand, and facilitates the assembly and disassembly of the footrest structure 50 on the other hand. In addition, since the locking screw 52 is hidden in the cylinder 51, it will not collide with the outside world. It should be noted that although Figures 2 to 5 It is shown that both the first side arm 111 and the second side arm 112 are provided with a footrest structure 50. Obviously, according to actual needs, the first side arm 111 or the second side arm 112 can also be provided with a footrest structure 50; Figures 2 to 5The figure is limited. In addition, "the locking screw 52 also passes through the cylinder 51 and is threadedly connected to the corresponding first side arm 111 or second side arm 112" means: when the first side arm 111 is provided with a footrest structure 50, the locking screw 52 is threadedly connected to the first side arm 111; when the second side arm 112 is provided with a footrest structure 50, the locking screw 52 is threadedly connected to the second hoop arm 112; when the first side arm 111 and the second side arm 112 are provided with footrest structures 50, the locking screw 52 of the footrest structure 50 on the first side arm 111 is threadedly connected to the first side arm 111, and the locking screw 52 of the footrest structure 50 on the second side arm 112 is threadedly connected to the second side arm 112.
[0030] like Figures 1 to 3 and Figure 5 As shown, as an example, the rear end 12 of the load-bearing frame 10 includes a fixed clamping block 121 and a dynamic clamping block 122. The dynamic clamping block 122 and the fixed clamping block 121 jointly enclose a clamping space 123, so that when the rear end 12 of the load-bearing frame 10 is assembled with the seat rod 240, the seat rod 240 can pass through the rear end 12 of the load-bearing frame 10 from the clamping space 123; a quick release assembly 60 is inserted into the dynamic clamping block 122 and the fixed clamping block 121 along the left and right directions of the load-bearing frame 10, and the quick release assembly 60 is also located outside the clamping space 123. The quick release assembly 60 is used to drive the dynamic clamping block 122 to move closer to the fixed clamping block 121, so as to meet the operator's need to use the quick release assembly 60 to make the dynamic clamping block 122 and the fixed clamping block 121 clamp or release the seat rod 240. Specifically, Figure 2 , Figure 3 and Figure 5 In the embodiment, as an example, the child seat mechanism 100 further includes a protective rubber pad 70 located in the clamping space 123, and the protective rubber pad 70 is respectively in close contact with the dynamic clamping block 122 and the fixed clamping block 121, so that the seat post 240 is effectively avoided from being scratched and damaged by the protective rubber pad 70, thereby extending the service life of the bicycle 200. In addition, the shock absorption effect between the rear end 12 of the load-bearing frame 10 and the seat post 240 can be appropriately increased. More specifically, as an example, the front end 11 of the load-bearing frame 10, the connecting bracket 30, the arc-shaped curved section 14, the straight section 15 and the fixed clamping block 121 are all carbon fiber structures, and the dynamic clamping block 122 and the quick release assembly 60 are all aluminum structures. Such a design can ensure that the child seat mechanism 100 is light and durable as a whole, for example, the load-bearing capacity is as high as about 100 kilograms.
[0031] Compared with the prior art, by virtue of the design that "a clamp groove 13 is provided on the front end 11 of the load-bearing frame 10 and penetrates the front end 11 forward, backward and downward, and the clamp groove 13 separates the front end 11 of the load-bearing frame 10 into a first side arm 111 and a second side arm 112", the front end 11 of the load-bearing frame 10 is conveniently clamped on the cross beam 211 of the frame 210 from above the cross beam 211 of the frame 210 by virtue of the clamp groove 13, thereby facilitating the assembly and disassembly operations between the load-bearing frame 10 and the cross beam 211 of the frame 210, without the need for complicated tools, thus saving time and effort; and when the front end 11 of the load-bearing frame 10 is clamped on the cross beam 211 of the frame 210, the first side arm 111 and the second side arm 112 also jointly clamp the cross beam 211, so as to increase the safety and stability of the connection while providing a strong load-bearing capacity. In addition, since the child seat mechanism 100 is respectively assembled and connected with the seat post 240 and the crossbeam 211 of the frame 210, there will be no interference when the rear wheel 230 of the bicycle 200 is folded, so that the bicycle 200 occupies a small space and is easy to carry when going out.
[0032] In summary, the bicycle system 100 of the present invention has the following four major features:
[0033] (1) The protective rubber pad 40 and the protective rubber pad 70 are used to provide personalized protection for the bicycle 100.
[0034] (2) The combination of the “clamp groove 13, the first side arm 111 and the second side arm 112” and the “fixed clamp block 121, the dynamic clamp block 122 and the quick-release assembly 60” not only provides a strong load-bearing capacity, but also ensures the stability and safety of the connection with the bicycle, and facilitates users to quickly install and disassemble without the need for complex tools, saving time and effort.
[0035] (3) The design of "the front end 11 of the load-bearing frame 10, the connecting bracket 30, the arc-shaped curved section 14, the straight section 15 and the fixed clamp block 121 are all carbon fiber structures, and the dynamic clamp block 122 and the quick-release assembly 60 are all aluminum structures" ensures that the child seat mechanism 100 is light, strong and durable as a whole.
[0036] (4) Multifunctionality and portability: The bicycle system 1000 of the utility model is a multifunctional product that has both a child seat function and a cycling travel function, and is a convenient companion for daily commuting and family travel. At the same time, it is light and easy to carry, providing a safe and comfortable riding environment for children at any time, and does not take up too much space. These features together constitute the unique charm of this product, which is not only highly practical, but also humanized in design, bringing great convenience and fun to users' travel.
[0037] It is worth noting that the direction indicated by arrow A in the drawings is the direction from front to back of the load-bearing frame 10, and the direction indicated by arrow B in the drawings is the direction from left to right of the load-bearing frame 10. In addition, since the specific structure of the quick-release assembly 60 is well known in the art, it will not be described in detail here.
