Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, and in particular to a fall-proof bicycle with an auxiliary support structure. Background Technology

[0002] With the rapid development of society and people's increasing emphasis on healthy lifestyles, bicycles, as an environmentally friendly, economical, and healthy mode of transportation, are receiving more and more attention. Especially in the process of children's growth, learning to ride a bicycle is not only a basic life skill, but also an important way to enhance physical coordination, balance, and independence. However, for beginners, especially children, it is easy to lose balance and fall while riding, which may not only lead to physical injury, but also cause psychological fear, thereby affecting children's interest and confidence in riding.

[0003] To help children learn riding skills, most children's bicycles on the market are equipped with two training wheels. These training wheels provide extra support by increasing the stability of the vehicle, helping children gradually master balance. However, the design of traditional training wheels has the following problems: First, traditional training wheels are usually fixed to the frame with bolts, and their angle and height cannot be adjusted. Although this design can provide stable support in the early stages of learning, as children gradually master balance, the fixed training wheels will limit the normal handling and flexibility of the vehicle, making it difficult to meet the learning needs at different stages. Second, as children's balance ability improves, the training wheels should be able to gradually reduce their contact area with the ground to encourage children to rely more on their own abilities to maintain balance. However, due to structural limitations, traditional training wheels cannot achieve this goal, making it difficult for children to transition from completely relying on training wheels to independent balance riding.

[0004] To address the aforementioned issues, a fall-resistant bicycle with an adjustable auxiliary support structure was developed. Utility Model Content

[0005] In order to overcome the shortcomings of traditional children's bicycles, such as fixed and non-adjustable training wheels, difficulty in gradually reducing dependence according to children's balance ability, and impact on the riding experience, this utility model provides a fall-proof bicycle with an adjustable auxiliary support structure.

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: a fall-resistant bicycle with an auxiliary support structure, comprising a frame, handlebars, a braking system, a front tire assembly, a seat, a rear tire assembly, pedals, a chain drive assembly, an arc-shaped guide rail, a swivel, an auxiliary support wheel, a lever, and a buckle. The frame consists of six main structures: a front fork, head tube, top tube, bottom tube, seat post, and rear fork. The handlebars are mounted on the head tube structure, and the braking system is installed on the handlebars. The front tire assembly is mounted on the front fork structure. The seat is slidably mounted on the upper end of the seat post structure. The rear tire assembly is mounted on the rear fork structure. The vehicle is equipped with a foot pedal assembly, and a chain drive assembly is provided between the foot pedal assembly and the rear tire assembly. Two arc-shaped guide rails are fixed to the rear fork structure of the frame. Multiple circular holes are provided on the arc-shaped guide rails. An auxiliary support wheel is rotatably mounted on each arc-shaped guide rail via a pivot. The two auxiliary support wheels are located on both sides of the rear tire assembly and can rotate along the arc-shaped guide rails with the pivot as the center. A square locking hole is provided on the bracket of the auxiliary support wheel. A locking rod is provided in the square locking hole. One end of the locking rod is a square structure that matches the square locking hole on the auxiliary support wheel, and the other end is a circular rod structure that cooperates with the circular hole on the arc-shaped guide rail. A buckle is sleeved on the rear end of the locking rod.

[0007] Furthermore, it also includes an arc-shaped support frame, an arc-shaped buffer block, and a damping shock absorber. The arc-shaped support frame is fixed to the front fork structure of the frame. The arc-shaped support frame is located above the front tire assembly. Multiple damping shock absorbers are installed on the arc-shaped support frame, and multiple damping shock absorbers are connected to one arc-shaped buffer block.

[0008] Furthermore, it also includes a fixed cylinder, a telescopic cylinder, and a buffer spring. The fixed cylinder is provided inside the seat post structure of the frame. One end of the telescopic cylinder is slidably disposed inside the fixed cylinder. The other end of the telescopic cylinder is connected to the seat cushion. The buffer spring is connected between the telescopic cylinder and the fixed cylinder.

[0009] Furthermore, it also includes a mudguard, which is provided on the rear fork structure of the frame and is located above the rear tire assembly.

[0010] Furthermore, it also includes limiting blocks, which are symmetrically distributed on the foot pedal of the foot pedal assembly.

[0011] Furthermore, it also includes a placement rack, which is provided on the upper tube structure of the frame.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. Through the design of arc-shaped guide rail, rotating shaft, locking rod and buckle, the auxiliary support wheel can realize the angle adjustment function. This design makes it convenient to adjust the contact area between the auxiliary support wheel and the ground according to the learning needs of different stages, gradually reduce the dependence on the auxiliary support wheel, and help children transition from complete dependence on the auxiliary support wheel to independent balance riding.

[0013] 2. Through the combined design of the arc-shaped buffer block and the damping shock absorber, the impact force generated by the front tire assembly during a collision can be significantly absorbed, reducing damage to the frame and rider, and further improving riding safety.

[0014] 3. Through the design of the fixed cylinder, telescopic cylinder and buffer spring between the seat and seat post structure, it can effectively absorb the impact of bumps caused by uneven road surfaces, reduce the rider's discomfort in complex road conditions, and improve the overall riding experience.

Detailed Implementation

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figures 1-4 A crash-resistant bicycle with an auxiliary support structure includes a frame 1, handlebars 101, a braking system 102, a front tire assembly 2, a seat 3, a rear tire assembly 4, pedals 5, a chain drive assembly 6, an arc-shaped guide rail 7, a pivot 701, an auxiliary support wheel 8, a lever 9, a buckle 901, a mudguard 16, a limiting block 17, and a mounting bracket 18. The frame 1 consists of six main components: a front fork, head tube, top tube, down tube, seat tube, and rear fork. The handlebars 101 are mounted on the head tube of the frame 1, and the brakes are installed on the handlebars 101. System 102, the top tube structure of frame 1 is provided with a storage rack 18, which can be used to place water bottles, providing convenient storage space for users. The front fork structure of frame 1 is equipped with a front tire assembly 2. The seat post structure of frame 1 is slidably mounted on the upper end of the seat post structure. The rear fork structure of frame 1 is equipped with a rear tire assembly 4. The rear fork structure of frame 1 is provided with a mudguard 16, which is located above the rear tire assembly 4, and is used to block mud and water splashed during riding, keeping the frame and rider clean. The lower end of the seat post structure of frame 1 The bicycle frame 1 is equipped with a pedal assembly 5, on which symmetrically distributed limiting blocks 17 are provided. The design of the limiting blocks 17 can prevent the foot from slipping off the side of the pedal during riding, thereby improving riding safety. A chain drive assembly 6 is provided between the pedal assembly 5 and the rear tire assembly 4. Two arc-shaped guide rails 7 are fixed to the rear fork structure of the frame 1. Five round holes are opened on the arc-shaped guide rails 7. An auxiliary support wheel 8 is rotatably mounted on each arc-shaped guide rail 7 via a pivot 701. The two auxiliary support wheels 8 are located on the left and right sides of the rear tire assembly 4, respectively. The auxiliary support wheel 8 can rotate along the arc-shaped guide rail 7 with the pivot 701 as the center, thereby achieving angle adjustment. The bracket of the auxiliary support wheel 8 has a square locking hole, and a locking rod 9 is set in the square locking hole. One end of the locking rod 9 is a square structure that matches the square locking hole on the auxiliary support wheel 8, and the other end is a round rod structure that cooperates with the round hole on the arc-shaped guide rail 7. The locking rod 9 passes through the square locking hole of the auxiliary support wheel 8 and then locks into the round hole of the arc-shaped guide rail 7, thereby fixing the auxiliary support wheel 8 at different angles. The rear end of the locking rod 9 is fitted with a buckle 901 to prevent the locking rod 9 from falling off.

[0025] When children use this bicycle, the auxiliary support wheel 8 provides balance support, helping them maintain a straight line and preventing falls. During the learning period, the contact area between the auxiliary support wheel 8 and the ground can be adjusted according to the child's balance ability at different stages. For example, initially, a larger contact area can be used to enhance stability, and later the contact area can be gradually reduced to encourage children to balance independently and reduce their dependence on the auxiliary support wheel 8. The actual steps for adjusting the auxiliary support wheel 8 are as follows:

[0026] First, remove the buckle 901 on the lever 9, then pull out the lever 9 to release the angle restriction of the auxiliary support wheel 8. Next, rotate the auxiliary support wheel 8 around the pivot 701 to a suitable angle, ensuring that the square locking hole of the auxiliary support wheel 8 is aligned with the round hole on the arc guide rail 7. Then, insert the lever 9 into the square locking hole and lock its rear end into the round hole on the arc guide rail 7. Put the buckle 901 on the rear end of the lever 9 to ensure that the lever 9 is fixed and prevents it from falling off. Through the above steps, the angle of the auxiliary support wheel 8 can be gradually adjusted upward along the position of the round hole on the arc guide rail 7, so that the auxiliary support wheel 8 gradually reduces the contact area with the ground, thereby helping children transition from complete reliance on the auxiliary wheel to independent balance riding.

[0027] Example 2: Based on Example 1, please refer to... Figure 5 It also includes an arc-shaped support frame 10, an arc-shaped buffer block 11, and a damping shock absorber 12. The arc-shaped support frame 10 is fixed to the front fork structure of the frame 1. The arc-shaped support frame 10 is located above the front tire assembly 2. Five damping shock absorbers 12 are installed on the arc-shaped support frame 10. The five damping shock absorbers 12 are connected to an arc-shaped buffer block 11.

[0028] When the front tire assembly 2 of the bicycle collides with a wall or other object during riding, the arc-shaped buffer block 11 acts as the first line of protection, directly contacting the object and bearing the initial impact force. At this time, the arc-shaped buffer block 11 transmits the impact force to the damping shock absorber 12 connected to it. The damping shock absorber 12 effectively absorbs most of the impact force through its internal damping element, and the remaining impact force is further transmitted to the arc-shaped support frame 10, thereby significantly reducing damage to the frame 1 and injury to the rider.

[0029] Please see Figure 6 and Figure 7 It also includes a fixed cylinder 13, a telescopic cylinder 14 and a buffer spring 15. The fixed cylinder 13 is provided inside the seat post structure of the frame 1. One end of the telescopic cylinder 14 is slidably provided inside the fixed cylinder 13. The other end of the telescopic cylinder 14 is connected to the seat cushion 3. A buffer spring 15 is connected between the telescopic cylinder 14 and the fixed cylinder 13.

[0030] When riding on uneven roads, the impact force generated by the bumpy road will be transmitted to the seat 3 through the frame 1. At this time, the telescopic cylinder 14 slides axially in the fixed cylinder 13 and compresses the buffer spring 15. The buffer spring 15 absorbs the impact force through its own elastic properties, thereby reducing the discomfort felt by the rider due to the bumpy road and protecting the frame 1 structure from excessive impact damage.

[0031] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
