Technical Field

[0001] The utility model relates to the technical field of children's bicycles, in particular to an anti-collision and anti-fall device for children's bicycles. Background Art

[0002] Children's bicycles are bicycles designed for children aged 4-8. They usually have smaller wheel diameters and saddles suitable for children's height. Children's bicycles are often used for children to learn to ride bicycles.

[0003] Most children's bicycles have poor anti-collision and anti-fall functions. When riding children's bicycles, because children's bodies are not fully developed and their limb coordination ability is still poor, they may lose balance and fall during riding, or fail to operate in time and cause a collision, causing injury to the children.

[0004] Therefore, in order to solve the above problems, a collision and fall prevention device for children's bicycles can be designed, which can be installed on the frame of children's bicycles, so that ordinary children's bicycles have collision and fall prevention functions, ensuring the safety of children's riding. Utility Model Content

[0005] In order to overcome the poor anti-collision and anti-fall functions of most children's bicycles, when riding children's bicycles, because children's bodies are not fully developed and their limb coordination ability is still poor, they may lose balance and fall during riding, or fail to operate in time and cause a collision, causing injuries to children.

[0006] The technical solution of the utility model is: an anti-collision and anti-fall device for a children's bicycle, comprising a bicycle body, a mounting frame, a mounting block, a rotating rod, a fixing seat, an anti-fall spring, a damper, an auxiliary wheel, an anti-collision frame and a buffer spring; a mounting block is provided at the bicycle body frame, a rotating rod is provided on one side of the mounting block, a mounting frame is provided on the outer side of the rotating rod, the rotating rod is rotatably connected to the mounting frame, a fixing seat is provided on the outer side of the mounting frame, an anti-fall spring is provided at the bottom of the fixing seat, a damper is provided on the inner side of the anti-fall spring, an auxiliary wheel is provided at the bottom of the anti-fall spring, an anti-collision frame is provided on one side of the mounting frame, and a buffer spring is provided on the inner side of the mounting frame.

[0007] Preferably, the fixing device is installed on the bicycle body, the mounting block is used to fix the mounting frame to the training wheel and the anti-collision frame, and the rotating rod is connected to the mounting frame through rotation, so that the device can adapt to the front and rear frames and different children's bicycles with the same set of structures. The anti-fall spring is installed on the fixing seat to absorb the kinetic energy of the child before falling through the training wheel when falling, thereby reducing the injury to the child. The damper is used to compress the anti-fall spring smoothly, and the buffer spring is used to absorb the impact force during collision, thereby reducing the injury to the child.

[0008] Preferably, one side of the mounting block is in an inwardly concave arc shape, and mounting threaded connectors are provided on both sides of the mounting block; the mounting block is connected and fixed by the mounting threaded connectors so that the rotatable rod can be fixed to the bicycle body.

[0009] Preferably, fixed blind holes are provided on the outer side of the rotating rod, and multiple groups of fixed blind holes are provided, and the fixed blind holes are arranged in a ring shape; the rotation of the rotating rod is conveniently restricted by the fixed blind holes.

[0010] Preferably, a rotating hole is provided on both sides of the mounting frame, a fixing hole is provided above the rotating hole, and a fixing screw is provided in the fixing hole; the rotating hole facilitates the rotation of the rotating rod, and the fixing hole accommodates the fixing screw to limit the rotation of the rotating rod.

[0011] Preferably, two sets of anti-falling guide rods are provided between the fixing seat and the auxiliary wheel, and the anti-falling guide rods are slidably connected to the fixing seat; the movement of the auxiliary wheel is guided by the anti-falling guide rods.

[0012] Preferably, two groups of sliding holes are opened on one side of the mounting frame, and anti-collision push blocks are provided on the inner side of the anti-collision frame. There are two groups of anti-collision push blocks, and the spacing between the sliding holes is equal to the spacing between the anti-collision push blocks; the sliding holes facilitate the sliding of the sliding guide rod, and the anti-collision push blocks are used to compress the buffer spring.

[0013] Preferably, a sliding guide rod is provided in the sliding hole, and a limit block is provided at one end of the sliding guide rod; the movement trajectory of the anti-collision frame is guided by the sliding guide rod.

[0014] Beneficial effects of the utility model:

[0015] 1. Compared with traditional children's bicycles, which have poor anti-collision and anti-fall functions, children may lose their balance and fall during riding, or crash due to inaccurate operation, which may cause injuries to children. This device provides a cushioning for children when they lose their balance and fall or are about to crash while learning to ride a children's bicycle, thereby reducing injuries to children and protecting their safety.

[0016] The anti-fall spring is compressed to cushion the child's fall, reducing the child's kinetic energy when falling and minimizing the risk of injury to the child. When the anti-fall frame contacts the object, the anti-fall push block compresses the buffer spring, the sliding guide rod slides in the sliding hole, guiding the movement of the anti-fall frame, and the limit block prevents the sliding guide rod from separating from the mounting frame. The damping has low movement capacity under rapid impact, so no damping is set in the buffer spring, so that the buffer spring can quickly absorb the impact force, reducing the impact force on the child and minimizing the injury to the child. This solves the problem that most children's bicycles have poor anti-collision and anti-fall functions. When riding a children's bicycle, because the child's body is not fully developed and the limb coordination ability is still poor, he may lose balance and fall during riding, or collide due to insufficient operation, which may cause injury to the child.

[0017] 3. When installing the device, place the two mounting blocks tightly against both sides of the bicycle tire frame, connect and tighten the mounting blocks using the mounting threaded connectors, align the rotating hole with the rotating rod, insert the rotating rod into the mounting bracket, and after adjusting the mounting bracket to a horizontal state, insert the fixing screws into the fixing holes and tighten them so that the fixing screws are inserted into the fixing blind holes, fix the rotating rod and the mounting bracket, and complete the installation of the device.

[0025] See also Figure 2 In this embodiment, one side of the mounting block 301 is concavely arc-shaped, and mounting threaded connectors 303 are provided on both sides of the mounting block 301. The mounting block 301 is connected and fixed by installing the threaded connector 303, so that the rotating rod 302 can be fixed to the bicycle body 1. The outer side of the rotating rod 302 is provided with a fixing blind hole 304, and there are multiple groups of fixing blind holes 304. The fixing blind holes 304 are arranged in a ring. The rotation of the rotating rod 302 is easily restricted by the fixing blind holes 304. Rotation holes 201 are opened on both sides of the mounting frame 2, and a fixing hole 202 is opened above the rotating hole 201. A fixing screw 203 is provided in the fixing hole 202. The rotation of the rotating rod 302 is facilitated by the rotating hole 201, and the fixing hole 202 is used to accommodate the fixing screw 203 to restrict the rotation of the rotating rod 302.

[0026] See also Figure 3 In this embodiment, two sets of anti-falling guide rods 401 are provided between the fixed seat 4 and the auxiliary wheel 7. The anti-falling guide rods 401 are slidably connected to the fixed seat 4, and the movement of the auxiliary wheel 7 is guided by the anti-falling guide rods 401.

[0027] See also Figure 4 In this embodiment, two groups of sliding holes 204 are opened on one side of the mounting frame 2, and an anti-collision push block 801 is provided on the inner side of the anti-collision frame 8. Two groups of anti-collision push blocks 801 are provided. The spacing between the sliding holes 204 is equal to the spacing between the anti-collision push blocks 801. The sliding holes 204 facilitate the sliding of the sliding guide rod 901, and the anti-collision push block 801 is used to compress the buffer spring 9. A sliding guide rod 901 is provided in the sliding hole 204, and a limiting block 902 is provided at one end of the sliding guide rod 901. The movement trajectory of the anti-collision frame 8 is guided by the sliding guide rod 901.

[0028] When installing the device, the two mounting blocks 301 are placed tightly against the two sides of the tire frame of the bicycle body 1, and the mounting blocks 301 are connected and tightened using the mounting threaded connectors 303. After aligning the rotating hole 201 with the rotating rod 302, the rotating rod 302 is inserted into the mounting frame 2. After adjusting the mounting frame 2 to a horizontal state, the fixing screws 203 are inserted into the fixing holes 202 and tightened. The fixing screws 203 are inserted into the fixing blind holes 304, and the rotating rod 302 is fixed to the mounting frame 2 to complete the installation of the device.

[0029] When the child loses balance and falls, the auxiliary wheel 7 on the falling side compresses the anti-fall spring 5, causing the auxiliary wheel 7 to move toward the fixed seat 4. The anti-fall guide rod 401 guides the movement of the auxiliary wheel 7, and the damper 6 ensures the smooth movement of the auxiliary wheel 7. The compression of the anti-fall spring 5 provides a buffer for the child's fall, reducing the kinetic energy of the child's fall and minimizing the harm to the child.

[0030] When impacted, the anti-collision frame 8 contacts the object and uses the anti-collision push block 801 to compress the buffer spring 9. The sliding guide rod 901 slides in the sliding hole 204 to guide the movement of the anti-collision frame 8. The limit block 902 prevents the sliding guide rod 901 from separating from the mounting frame 2. The damping has low movement ability when subjected to rapid impact. Therefore, no damping is set in the buffer spring 9, so that the buffer spring 9 can quickly absorb the impact force, reduce the impact force on the child, and reduce the injury to the child.

[0031] Through the above steps, the fixing device is installed on the bicycle body 1, the mounting block 301 is used to fix the mounting frame 2 to the auxiliary wheel 7 and the anti-collision frame 8, and the rotating rod 302 is connected to the mounting frame 2 for rotation, so that the device can adapt to the front and rear frames and different children's bicycles with the same set of structures. The anti-fall spring 5 is installed on the fixing seat 4 to absorb the kinetic energy of the child before falling through the auxiliary wheel 7 when falling, thereby reducing the damage to the child. The damper 6 is used to compress the anti-fall spring 5 smoothly, and the buffer spring 9 is used to absorb the impact force during collision, thereby reducing the damage to the child.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
