[0035] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0036] Please see Figure 1 The bicycle 1000 of this utility model includes a child riding mechanism 100, a frame 200, a front wheel 300, a rear wheel 400, a seat post 500, and a handlebar 600 mounted on the frame 200. The lower end of the handlebar 600 is assembled and connected to the front wheel 300. Since the specific structures of the handlebar 600, seat post 500, rear wheel 400, front wheel 300, and frame 200 are well known in the art and are not improvements of this application, they will not be described in detail here.

[0037] Combined Figures 2 to 5 The child seating mechanism 100 includes a support frame 10 and a seat 20 for children to sit in. The support frame 10 has upper and lower support sections 11 and a transverse support section 12, which are arranged at an angle. The upper and lower support sections 11 provide support in the vertical direction, and the transverse support section 12 provides support in the vertical direction. The transverse support section 12 has a first assembly structure 121 at the end away from the upper and lower support sections 11 for assembly and connection with the upright (specifically the seat post 500) of the bicycle 1000. The upper and lower support sections 11 have a second assembly structure 111 at the end away from the transverse support section 12 for assembly and connection with the crossbeam 210 of the bicycle 1000. Therefore, with the cooperation of the first assembly structure 121 and the second assembly structure 111, the child riding mechanism 100 can be assembled on both the crossbeam 210 and the seat post 500 of the frame 200, so that the child riding mechanism 100 will not interfere with the front end 600 of the bicycle 1000, and thus will not affect the steering operation of the front end 600.

[0038] The seat 20 is mounted on the transverse support section 12, which provides support for the seat 20. The seat 20 also features a grip structure 30 for children to hold onto, making the child seating mechanism 100 resemble a saddle, thus allowing children to ride in a straddling position. It should be noted that although... Figures 1 to 9 The image shows the grip structure 30 being provided by the seat 20. However, depending on actual needs, the grip structure 30 can also be provided by the support frame 10 (specifically, by the transverse support section 12). Therefore, it is not considered... Figures 1 to 9The above is a limited description. For more specific details, please see the description below.

[0039] like Figure 4 and Figure 5 As shown, as an example, the seat 20 can be arranged in an adjustable position along the length of the transverse support section 12 (as indicated by double arrow A). An operating element 40 is provided between the seat 20 and the transverse support section 12 for locking or unlocking the seat 20 and the transverse support section 12. Therefore, with the help of the operating element 40, the operator can flexibly adjust the position of the seat 20 on the transverse support section 12 according to actual needs, better meeting the child's seating needs. Specifically, in conjunction with... Figures 4 to 9 As an example, seat 20 is located above the transverse support section 12 and includes a seat frame 21 and a soft seat cushion 22 covering the seat frame 21. The seat frame 21 has an internal thread structure 211, and the transverse support section 12 has an adjustment section 122 that runs vertically through it. The operating member 40 passes through the adjustment section 122 from below and is threadedly connected to the internal thread structure 211. This design facilitates the operator's adjustment of the seat 20's position, and the flexible seat cushion 22 ensures that children do not feel tired after sitting for extended periods. The seat cushion 22's coverage of the seat frame 211 facilitates the manufacture of seat 20 using in-mold molding, thus simplifying the manufacturing process of seat 20. Furthermore, the seat frame 211 ensures that seat 20 has sufficient support rigidity. More specifically, in Figure 4 and Figure 5 As an example, the adjustment section 121 is an elongated hole extending along the length of the transverse support section 12 to meet the need for the seat 20 to be adjustable over a wide range.

[0040] Combination Figures 2 to 9 As an example, the child seating mechanism 100 also includes a screw 50 (see...). Figure 5 The front end of the seat frame 21 is bent upward to form a raised structure 212 for assembly with the grip structure 30. Screws 50 pass through the grip structure 30 and the raised structure 212 in the vertical direction to lock the grip structure 30 and the raised structure 212 together. This design allows the grip structure 30 to be mounted on the seat 20, facilitating assembly and disassembly between the grip structure 30 and the seat 20. Furthermore, the design of the raised structure 212 provides more operating space for the screws 50 to lock or release the grip structure 30 and the raised structure 212. Obviously, depending on actual needs, a one-piece manufacturing process can also be used to make the grip structure 30 and the seat 20 a single unit; therefore, it is not necessary to... Figures 2 to 9 As shown is for illustrative purposes only. Additionally, the grip structure 30 is higher than the seat 20 to facilitate a child's gripping and operation; furthermore, the grip structure 30 is a ring-shaped structure, such as, but not limited to, a ring-shaped structure that is smaller at the bottom and larger at the top, further facilitating a child's gripping and operation; and at... Figure 9In the middle, the seat 20 is a downward convex arc shape, so that the seat 20 can better fit the child and also prevent the child from running around in the length direction of the transverse support section 12, thus increasing the stability of the ride.

[0041] like Figures 1 to 5 As shown, as an example, the first assembly structure 121 is a clamping structure to facilitate quick assembly and disassembly between the transverse support section 12 and the seat post 500; the second assembly structure 111 is an open-bottomed annular structure, which further facilitates quick assembly and disassembly between the upper and lower support sections 11 and the crossbeam 210 of the frame 200; in addition, the two ends of the annular structure are provided with outwardly protruding footrests 213 for children to rest their feet, thereby meeting the needs of children to rest their feet and improving the comfort of children riding. Specifically, in Figures 2 to 5 In this example, the second assembly structure 111 is covered with a plastic layer 112 to increase the gripping force of the second assembly structure 111 on the crossbeam 210, effectively improving the stability between the upper and lower support sections 11 and the crossbeam 210. Furthermore, the foot support structure 213 can be assembled onto the second assembly structure 111 via a threaded connection, or it can be manufactured as a single unit with the second assembly structure 111 using an integrated manufacturing process. It should be noted that since the second assembly structure 111 is covered with a plastic layer 112, it can be manufactured using an in-mold molding method.

[0042] like Figures 3 to 5 and Figures 10 to 12 As shown, as an example, the child seating mechanism 100 also includes a screw 80 and a nut 90. In this case, a first pivot structure 60 is provided on the end of the upper and lower support sections 11 near the end of the transverse bearing section 12. A first through hole 61 for the screw 80 to pass through is provided at the center of the first pivot structure 60. The first pivot structure 60 also has multiple first engagement teeth 62 arranged around the center line of the first through hole 61. Optionally, in… Figure 11 In the example shown, all the first occlusal teeth 62 are arranged in a circle. Obviously, depending on actual needs, all the first occlusal teeth 62 can also be arranged in a ring of less than 360 degrees. Therefore, this is not considered an example. Figure 11 The above is the limit.

[0043] Meanwhile, a second pivot structure 70 is assembled on the end of the horizontal bearing section 12 near the upper and lower support sections 11. A second through hole 71 for the screw 80 to pass through is opened at the center of the second pivot structure 70. The second pivot structure 70 also has multiple second engagement teeth 72 arranged around the center line of the second through hole 71 and cooperating with the first engagement teeth 62. Optionally, in... Figure 12 In the example shown, all the second occlusal teeth 72 are arranged in a circle. Obviously, depending on actual needs, all the second occlusal teeth 72 can also be arranged in a ring of less than 360 degrees. Therefore, it is not considered as such. Figure 12 The above is the limit.

[0044] Furthermore, the screw 80 passes through the first through hole 61 and the second through hole 71 and is threadedly connected to the nut 90. Therefore, by adjusting the position of the nut 90 on the screw 80, the engagement or disengagement between the first engagement tooth 62 and the second engagement tooth 72 can be achieved accordingly. When the first engagement tooth 62 and the second engagement tooth 72 are disengaged, the included angle between the upper and lower support sections 11 and the transverse bearing section 12 can be adjusted to better meet the riding needs of children. Specifically, during the adjustment process between the upper and lower support sections 11 and the transverse bearing section 12, the nut 90 needs to be rotated in the direction of unscrewing the screw 80, so that the nut 90 and the screw 80 release the pressure on the first pivot structure 60 and the second pivot structure 70, thereby allowing the first pivot structure 60 and the second pivot structure 70 to move relative to each other in the axial direction of the screw 80, in preparation for the disengagement of the first engagement tooth 62 and the second engagement tooth 72; after the first engagement tooth 62 and the second engagement tooth 72 disengage, the operator is allowed to rotate the upper and lower support sections 11 and / or the transverse bearing section 12; when the upper and lower support sections 11 and the transverse bearing section 12 are adjusted to the appropriate position, the nut 90 is then rotated in the direction of screwing into the screw 80 until the nut 90 and the screw 80 together engage and fix the first engagement tooth 62 and the second engagement tooth 72. It should be noted that during the angle adjustment process between the upper and lower support sections 11 and the horizontal bearing section 12, since the central angle between two adjacent first meshing teeth 62 is fixed, the angle adjustment is controlled by the number of teeth passed, so the angle adjustment is better controlled.

[0045] It should be noted that, although Figures 10 to 12 The diagram shows the first pivot structure 60 assembled onto the upper and lower support sections 11, and the second pivot structure 70 assembled onto the transverse load-bearing section 12. Clearly, depending on actual needs, a one-piece manufacturing process can also be used to integrate the first pivot structure 60 with the upper and lower support sections 11, and the second pivot structure 70 with the transverse load-bearing section 12. Therefore, it is not necessary to use a one-piece manufacturing process. Figures 10 to 12 The above is for reference only. Also, although... Figures 1 to 5 The diagram demonstrates the assembly connection between the upper and lower support sections 11 and the transverse load-bearing section 12 via a first pivot structure 60, a second pivot structure 70, a screw 80, and a nut 90. Clearly, depending on actual needs, the upper and lower support sections 11 and the transverse load-bearing section 12 can also be directly assembled together, making the angle between them non-adjustable; alternatively, an integrated manufacturing process can be used to make the upper and lower support sections 11 and the transverse load-bearing section 12 a single unit. Therefore, it is not necessary to... Figures 1 to 5 The above is a limited description. Furthermore, regarding… Figure 5In this example, the upper and lower support sections 11 and the horizontal bearing section 12 are each tubular structures, such that the first pivot structure 60 can be inserted into the upper and lower support sections 11, and the second pivot structure 70 can be inserted into the horizontal bearing section 12.

[0046] Compared with existing technologies, by using the grip structure 30 mounted on the support frame 10 or seat 20 for children to hold, children can ride in the child riding mechanism 100 in a riding manner. This reduces the difficulty for riders to control the front of the vehicle 600 and increases the stability and reliability of the ride, while also enhancing the riding experience for children.

[0047] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
