Description

Technical Field

[0001] This utility model belongs to the field of children's bicycle technology, and in particular relates to a children's learning bicycle with anti-fall protection function. Background Technology

[0002] Children's bicycles are bicycles specifically designed for children to ride. When children are learning to ride, guardians hold the bicycle to keep it stable. However, when the guardians let go of the bicycle, the child's center of gravity shifts slightly, which can lead to a fall. In the process of falling, it is difficult for the guardians to react in time, resulting in the child falling and getting injured. Utility Model Content

[0003] The purpose of this utility model is to provide a children's learning bicycle with anti-fall protection function in order to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a children's learning bicycle with anti-fall protection function, comprising a bicycle body, an auxiliary frame, a first support wheel, two telescopic joints and two second support wheels. The auxiliary frame is fixedly connected to the frame of the bicycle body and surrounds the rear wheel of the bicycle body. The first support wheel is hinged to the auxiliary frame. The two telescopic joints are installed on the auxiliary frame and are located on opposite sides of the rear wheel. The two second support wheels are respectively connected to the two telescopic joints through two support rods.

[0005] As a further description of the above technical solution:

[0006] The axle of the first support wheel, the axles of the two second support wheels, and the axle of the rear wheel are parallel.

[0007] As a further description of the above technical solution:

[0008] The auxiliary frame is provided with a sliding groove, the support rod is slidably connected in the sliding groove, and the second support wheel is hinged to the support rod.

[0009] As a further description of the above technical solution:

[0010] The inner wall of the slide is provided with a limiting groove, and the support rod is provided with a limiting strip, which is inserted into the limiting groove.

[0011] As a further description of the above technical solution:

[0012] The auxiliary frame is equipped with multiple reinforcing ribs.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] In this invention, an auxiliary frame is installed at the rear of the bicycle body. The first support wheel provides structural support for the auxiliary frame, while the telescopic device and the second support wheel support the stability of the bicycle body. When children are learning to ride, both the first and second support wheels are against the ground, providing stability and eliminating their fear. Controlling the telescopic device to retract causes the second support wheel to lift off the ground, allowing children to truly control the two-wheeled bicycle body and find the feeling of riding. Even if the center of gravity is unstable and the child leans to one side during riding, the corresponding second support wheel will provide support, thus preventing the child from falling and getting injured.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a children's learning bicycle with anti-fall protection function, including a bicycle body 1, an auxiliary frame 2, a first support wheel 3, two telescopic devices 4 and two second support wheels 5. The auxiliary frame 2 is fixedly connected to the frame of the bicycle body 1 and surrounds the rear wheel 6 of the bicycle body 1. The first support wheel 3 is hinged to the auxiliary frame 2. The two telescopic devices 4 are installed on the auxiliary frame 2 and are located on opposite sides of the rear wheel 6. The two second support wheels 5 are respectively connected to the two telescopic devices 4 through two support rods 7. The telescopic devices 4 can be servo electric cylinders. When in use, a mobile power supply is installed on the auxiliary frame 2 for power supply. A remote controller can be installed so that the guardian can remotely control the extension and retraction of the telescopic devices 4, thereby controlling the raising and lowering of the second support wheels 5.

[0023] The axle of the first support wheel 3, the axles of the two second support wheels 5, and the axle of the rear wheel 6 are parallel to ensure stable riding.

[0024] The auxiliary frame 2 is provided with a sliding groove 8, the support rod 7 is slidably connected in the sliding groove 8, the second support wheel 5 is hinged to the support rod 7, and the sliding groove 8 has a guiding function for the sliding of the support rod 7;

[0025] The inner wall of the slide groove 8 is provided with a limiting groove 9, and the support rod 7 is provided with a limiting strip 10. The limiting strip 10 is inserted into the limiting groove 9 to ensure the sliding stability of the support rod 7. The limiting effect of the limiting groove 9 on the limiting strip 10 can resist the torsional force on the support rod 7 itself.

[0026] The auxiliary frame 2 is provided with multiple reinforcing ribs 11 to ensure the stability of the structure.

[0027] Working principle: An auxiliary frame 2 is installed at the rear of the bicycle body 1. The first support wheel 3 provides structural support for the auxiliary frame 2. The telescopic device 4 and the second support wheel 5 support the stability of the bicycle body 1. When children are learning to ride, both the first support wheel 3 and the second support wheel 5 are against the ground, providing stability and eliminating children's fear. Controlling the telescopic device 4 to retract will lift the second support wheel 5 off the ground. That is, the telescopic device 4 can be a servo electric cylinder. When in use, a mobile power supply is installed on the auxiliary frame 2 for power supply. A remote controller can be installed so that the guardian can remotely control the extension and retraction of the telescopic device 4, thereby controlling the raising and lowering of the second support wheel 5. The slide groove 8 guides the sliding of the support rod 7, and the limiting groove 9 limits the limiting strip 10, which can resist the torsional force on the support rod 7 itself, allowing children to truly control the two-wheeled bicycle body 1 to ride and find the feeling of riding. Even if the center of gravity is unstable and the child leans to one side during riding, the corresponding second support wheel 5 will provide support, thus preventing the child from falling and getting injured.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
