Description

Technical Field

[0001] This utility model relates to the field of bicycle auxiliary equipment technology, specifically an anti-collision and anti-tipping device for children's bicycles. Background Technology

[0002] Children's bicycles, as the name suggests, are bicycles designed for children. In today's society, children's growth is of great importance, and parents cultivate various skills in their children from a young age. As a result, riding a bicycle has become a common choice for parents. However, during the process of children learning to ride a bicycle, they are prone to falling or colliding with other dangerous things, which is quite troublesome.

[0003] As disclosed in the prior art, Chinese utility model publication CN213502736U discloses an anti-collision and anti-tipping device for children's bicycles, including a seat, handlebars, anti-collision protection device, connecting shaft, interlocking connecting shaft, front wheel, connecting rod, pedals, outer anti-tipping universal wheel, connecting frame, frame, and rear wheel. The bottom of the seat is welded to the middle of the upper surface of the frame via the frame rod. The bottom of the handlebars is fixedly connected to the interlocking connecting shaft with screws. The anti-collision protection device is installed on the outer surface of the frame. A sponge layer is embedded in the outer layer of the anti-collision protection device. The inner side of the sponge layer is firmly connected to the buffer layer. The vertical ends on the left and right sides of the buffer layer are embedded in the buffer groove and connected to the buffer spring. The inner wall of the buffer layer is provided with a connecting plate and is fixedly connected with screws. The bottom of the connecting plate is fixedly connected to the upper end of the shock-absorbing spring.

[0004] As can be seen from the above-mentioned anti-collision and anti-tipping devices for children's bicycles, children are prone to falling or colliding while learning to ride a bicycle. Although the above-mentioned anti-collision and anti-tipping devices can play a certain role in preventing tipping in actual use, the overall structure is large and it is troublesome to disassemble and assemble, making it inconvenient to store. Moreover, after the child has learned to ride a bicycle, the device may actually hinder the child's normal riding. Therefore, we need to propose an anti-collision and anti-tipping device for children's bicycles. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-collision and anti-tipping device for children's bicycles, which can not only effectively reduce the danger of children falling or colliding while riding and improve riding safety, but also make it easy to disassemble and install the anti-collision and anti-tipping device for storage. At the same time, it prevents the anti-collision and anti-tipping device from affecting the child's normal riding after the child learns to ride a bicycle, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides: an anti-collision and anti-tipping device for a children's bicycle, including a frame, a front fork frame mounted at the front end of the frame, mounting frames connected to both sides of the front fork frame, an anti-collision buffer assembly movably inserted inside the mounting frames, a front anti-collision frame connected to the end of the connecting rod of the anti-collision buffer assembly, and an anti-collision pad detachably mounted on the surface of the front anti-collision frame; fixed frames mounted on both sides of the frame, side mounting members detachably mounted on the surface of the fixed frames, and an anti-tipping support assembly connected to the bottom end of the side mounting members via a fixed plate; and a side anti-tipping frame connected to the outer side of the fixed plate.

[0007] Preferably, the anti-collision buffer assembly includes: a mounting base slidably connected to one end of the surface of the connecting rod, and positioning strips connected to both sides of the mounting base; wherein the surface of the positioning strips is movably inserted into the inner wall of the mounting frame, and a limit stop is connected to one side of the mounting base on the surface of the connecting rod.

[0008] Preferably, a buffer spring is provided inside the mounting base, the buffer spring is sleeved on the surface of the connecting rod, and one end of the buffer spring is connected to the inner surface of the limiting stop plate.

[0009] Preferably, the surface of the anti-collision pad is connected to a locking part, and the locking part is bolted to the surface of the front anti-collision frame.

[0010] Preferably, the anti-tipping support assembly includes: a connecting plate movably mounted on the surface of the fixed plate, and an anti-tipping caster wheel movably mounted on the bottom end of the connecting plate; wherein, a compression spring is provided below the fixed plate, and the compression spring is fitted onto the surface of the connecting plate.

[0011] Preferably, a locking positioning rod is connected to the surface of the fixing frame, and the side mounting component is movably mounted on the surface of the locking positioning rod.

[0012] Preferably, a connecting bracket is connected to the outer side of the fixing plate, and the side anti-tipping bracket is connected to the outer end of the connecting bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model, through the coordinated design of a frame, front anti-collision frame, side anti-tipping frame, anti-collision buffer assembly, and anti-tipping support assembly, effectively cushions the impact of a collision during riding by using the anti-collision pad and the buffer spring inside the mounting seat that works with the connecting rod, ensuring the child's smooth and safe riding. Simultaneously, the anti-tipping casters mounted on the side mounting brackets on the surface of the fixed frame provide balance, effectively reducing the likelihood of the bicycle tipping over. The front anti-collision frame and side anti-tipping frame can be easily disassembled and stored by the mounting frame and the positioning strips on both sides of the mounting seat, as well as the fixed frame and side mounting brackets. This also prevents the anti-collision and anti-tipping devices from interfering with the child's normal riding after they have learned to ride. Attached Figure Description
