Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, specifically a convenient two-in-one convertible children's bicycle. Background Technology

[0002] Children's bicycles, as an important tool for children's exercise and recreation during their growth, are widely popular in the market. Currently, children's bicycles on the market are constantly evolving in design and manufacturing processes, achieving progress in frame structure, braking systems, and comfort features to meet children's daily riding needs.

[0003] However, existing children's bicycles generally have a significant drawback: they cannot switch between gliding and pedaling modes. For younger children who have not yet mastered riding skills, the gliding function helps them gradually become familiar with balance and directional control. As children's riding ability improves, pedaling can better train their leg muscle strength and body coordination.

[0004] However, existing children's bicycles lack the ability to switch between these two modes, which limits their usability for children of different ages and riding abilities. This not only restricts the usage scenarios of children's bicycles but also affects the richness and continuity of children's riding experience to some extent. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a convenient two-in-one convertible children's bicycle to solve the technical problem that existing children's bicycles cannot switch between gliding and riding modes, resulting in significant limitations in overall use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a convenient two-in-one convertible children's bicycle, including a frame, wherein the frame includes a frame body, a first locking hole and a second locking hole;

[0007] The first locking hole and the second locking hole are formed on the frame body. The bottom of the frame body is connected to a sliding module. The sliding frame of the sliding module includes a first mating hole and a first corresponding hole. The first mating hole, the first corresponding hole and the first locking hole and the second locking hole are correspondingly connected. The first mating hole and the first corresponding hole are formed on the sliding frame.

[0008] The first mating hole, the first corresponding hole, the first locking hole, and the second locking hole are respectively connected by bolts, and the second mating hole, the second corresponding hole, the first locking hole, and the second locking hole are respectively connected by bolts.

[0009] The bottom of the frame body can also be connected to a self-propelled module. The self-propelled module includes a self-propelled frame, a second mating hole and a second corresponding hole, and the second mating hole, the second corresponding hole and the first locking hole and the second locking hole are correspondingly connected. The second mating hole and the second corresponding hole are opened on the self-propelled frame.

[0010] The frame also includes a rear wheel frame, rear wheel mounting holes, a front wheel mounting sleeve, and a seat mounting sleeve. The two sets of rear wheel mounting holes are coaxially formed inside the rear wheel frame. The front wheel mounting sleeve is located at the front end of the frame body, and the handlebar assembly is installed inside the front wheel mounting sleeve. The seat mounting sleeve is located at the top middle of the frame body, and the seat assembly is installed inside the seat mounting sleeve.

[0011] The self-propelled module also includes sprocket mounting holes, which are located inside the self-propelled frame.

[0012] By adopting the above technical solution, its unique design allows for convenient switching between gliding and self-propelled modes, fully meeting the needs of children of different ages and riding abilities.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Example 1

[0023] A convenient two-in-one convertible children's bicycle, such as Figure 1-5 As shown, it consists of a frame 1, a gliding module 2, and a self-propelled module 3. The frame 1 is made of high-strength aluminum alloy and manufactured through precision casting, which ensures sufficient strength while reducing the overall weight and making it easy for children to operate.

[0024] The frame 1 includes a frame body 101, a rear wheel frame 102, a rear wheel mounting hole 103, a front wheel mounting sleeve 104, a seat mounting sleeve 105, a first locking hole 106, and a second locking hole 107. The rear wheel frame 102 is integrally formed with the frame body 101. The two sets of rear wheel mounting holes 103 are coaxially formed inside the rear wheel frame 102 for mounting the rear wheel axle.

[0025] The front wheel mounting sleeve 104 is welded to the front end of the frame body 101 and can fit tightly with the handlebar assembly. The seat mounting sleeve 105 is located at the top middle of the frame body 101 and can securely install the seat assembly. The first locking hole 106 and the second locking hole 107 are opened at the bottom of the frame body 101 for connecting the gliding module 2 or the self-propelled module 3. The frame body 101 has a hollow structure inside, which facilitates the installation of the gliding module 2 or the self-propelled module 3.

[0026] The sliding frame 201 of the sliding module 2 is made of high-strength aluminum alloy and is machined, which has good strength and corrosion resistance. The sliding frame 201 is provided with a first mating hole 202 and a first corresponding hole 203. The diameter of the holes is the same as the first locking hole 106 and the second locking hole 107 on the frame 1. The positions of the first mating hole 202 and the first corresponding hole 203 are precisely corresponding to the first locking hole 106 and the second locking hole 107 to ensure accurate alignment during installation.

[0027] The self-propelled frame 301 of the self-propelled module 3 is also made of high-strength aluminum alloy and is machined. The self-propelled frame 301 is provided with a second mating hole 302, a second corresponding hole 303 and a sprocket mounting hole 304. The diameter of the second mating hole 302 and the second corresponding hole 303 are the same as the connection method of the frame 1 and the sliding module 2.

[0028] The sprocket mounting hole 304 is located inside the bicycle frame 301 and is used to install the main sprocket. The bicycle module 3 is equipped with rubber tires as the rear wheel and rubber tires as the front wheel. The tire surface has anti-slip treads to increase friction with the ground and improve riding safety. In addition, the bicycle module 3 also includes a chain, a main sprocket, and a secondary sprocket. The main sprocket is installed in the sprocket mounting hole 304, and the secondary sprocket is installed on the rear wheel axle. The main sprocket and the secondary sprocket are connected and meshed with each other through the chain to realize power transmission.

[0029] glider assembly

[0030] When children are young and have not yet mastered riding skills, assemble the bicycle into gliding mode. First, align the first mating hole 202 of the gliding module 2 with the first locking hole 106 at the bottom of the frame body 101, and align the first corresponding hole 203 with the second locking hole 107. Use an M8 bolt to pass through the mating hole and the locking hole, and then tighten it with a nut to ensure a firm connection.

[0031] Next, insert the handle assembly into the front wheel mounting cylinder 104, and fix the handle position by tightening the fastening bolts on the cylinder wall. Then insert the seat assembly into the seat mounting cylinder 105, adjust it to a suitable height, and fix the seat using the matching fastening device. Finally, check whether each connection part is stable and whether the gliding wheels rotate flexibly. After confirming that everything is correct, the gliding vehicle assembly is complete.

[0032] Bicycle assembly

[0033] When a child’s riding ability improves and it is necessary to convert the glider into a bicycle, first use a tool to unscrew the bolts connecting the glider module 2, remove the glider module 2 from the frame body 101, and then align the second mating hole 302 of the bicycle module 3 with the first locking hole 106, align the second corresponding hole 303 with the second locking hole 107, connect with an M8 bolt and tighten the nut.

[0034] Next, install the main sprocket into the sprocket mounting hole 304, ensuring a secure installation. Install the auxiliary sprocket on the rear wheel axle, so that the main sprocket and auxiliary sprocket are connected and engaged through the chain. Since the bicycle module 3 and the frame 1 are connected by a rotatable connection, after installation, rotate the bicycle module 3 to rotate along the first locking hole 106, adjusting the distance between the main sprocket and auxiliary sprocket, thereby adjusting the chain tension to ensure the chain is in a suitable tension, avoiding excessive looseness that could cause the chain to fall off or excessive tightness that could affect the smoothness of riding. Finally, check whether the chain is installed correctly, whether the tire pressure is sufficient, and whether the connections of each component are secure, ensuring that the bicycle can be used safely.

[0035] Use and Maintenance

[0036] During use, children can choose between gliding mode or bicycle mode according to their own situation. After use, regularly check all parts of the bicycle, such as whether the bolts are loose, the tire wear, and the chain lubrication. Tighten the bolts in time if they are loose; replace the tires when they are severely worn; and lubricate the chain with special bicycle lubricant when it is dry to ensure that the bicycle is always in good working order and to ensure the safety and experience of children riding.
