Description

Technical Field

[0001] The utility model relates to a children's bicycle with a stable and collision-proof structure, belonging to the technical field of children's bicycles. Background Art

[0002] A children's bicycle is a bicycle suitable for children aged 4-8 years old. It is ridden by a driving mechanism acting on the rear wheel. It has various wheel diameters and styles, with or without a balance wheel. Some children's bicycles are also equipped with a protective wheel, i.e. a balance wheel, which can help the rider maintain balance. Therefore, when purchasing, pay attention to whether it is equipped with one balance wheel on each side. Do not remove it at will during use to avoid the child's rollover.

[0003] According to the authorized patent CN202222074271.4, this patent provides an anti-collision mechanism to facilitate adjustment of the protective position of the arc-shaped anti-collision pad, so as to maximize the buffering and collision prevention of children of different heights during riding, significantly improving the safety of children's riding. However, in the event of a collision, it is basically the front end of the bicycle that collides, and there is no anti-collision buffering mechanism at the front end of the bicycle. At the same time, when the adult is not around the child, it cannot be discovered in time. At the same time, the existing children's bicycles cannot protect the waist of the child according to the child's height. Utility Model Content

[0004] The purpose of the utility model is to provide a children's bicycle with a stable and anti-collision structure. The utility model has a simple structure and is easy to use. It can perform anti-collision and buffering treatment on the front end of the bicycle, and can alarm when a collision occurs. The waist guard plate of the seat can be adjusted according to the height of the child, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A children's bicycle with a stable and anti-collision structure comprises a bicycle body, a seat is fixedly connected to the top of the bicycle body, an anti-collision alarm mechanism is fixedly connected to the outer side of the bicycle body, and a waist protection mechanism is fixedly connected to the outer side of the seat.

[0007] The anti-collision alarm mechanism includes a connecting rod, a stabilizing plate is fixedly connected to the outer side of the connecting rod, a buffer tube is fixedly connected to the outer side of the stabilizing plate, a nylon rod is movably connected to the inside of the buffer tube, a force-bearing plate is fixedly connected to the outer side of the nylon rod, a shock-absorbing spring is fixedly connected to the outer side of the buffer tube, a sponge is fixedly connected to the outer side of the force-bearing plate, a connecting rod is fixedly connected to the inner side of the force-bearing plate, an extrusion cover is fixedly connected to the outer side of the connecting rod, a power box is fixedly connected to the outer side of the stabilizing plate, an elastic switch is fixedly connected to the outer side of the power box, and an alarm is fixedly connected to the top of the power box.

[0008] The waist protection mechanism includes a limit plate, a lifting groove is provided inside the limit plate, an extension plate is movably connected inside the lifting groove, a threaded tube is fixedly connected to the outer side of the limit plate, a screw is threadedly connected inside the threaded tube, and a positioning hole is provided inside the extension plate.

[0009] Furthermore, the stabilizing plate is fixedly connected to the outside of the bicycle body through a connecting rod, the buffer tubes are symmetrically distributed on the outside of the stabilizing plate, and the stabilizing plate is fixedly connected to the front end of the bicycle body through the connecting rod.

[0010] Furthermore, the force-bearing plate and the sponge body are located in front of the bicycle body, and one end of the shock-absorbing spring away from the buffer tube is fixedly connected to the outside of the force-bearing plate. Through the coordinated use of the force-bearing plate and the sponge body, preliminary buffering treatment can be performed on the impact.

[0011] Furthermore, the connecting rod and the extrusion cover are located between the force-bearing plate and the stabilizing plate, and the extrusion cover and the elastic switch are on the same plane. The force-bearing plate is subjected to impact force, so that the connecting rod drives the extrusion cover to squeeze the elastic switch.

[0012] Furthermore, the alarm is electrically connected to the power box, and the extension plate is movably connected to the inside of the lifting slot. When the elastic switch is squeezed, the power box is energized, thereby causing the alarm to sound, thus alerting adults.

[0013] Furthermore, the positioning holes are evenly distributed inside the extension plate, and one end of the screw rod is located inside the positioning hole. The screw rod is located inside the positioning hole, so that the extension plate inside the lifting slot is positioned.

[0014] The beneficial effects of the utility model are:

[0015] The utility model is provided with a bicycle body, a connecting rod is fixedly connected to the outside of the bicycle body, and a stabilizing plate is fixedly connected to the outside of the bicycle body through the connecting rod. When the front end of the bicycle body is impacted, the impact force can be preliminarily buffered by the cooperation of the sponge body and the force-bearing plate. At this time, the force-bearing plate is moved. Since a shock-absorbing spring is fixedly connected to the outside of the force-bearing plate, the impact force is buffered. The nylon rod is moved back and forth inside the buffer tube to eliminate the generated potential energy. At this time, the connecting rod is driven to move by the movement of the force-bearing plate, so that the extrusion cover outside the connecting rod squeezes the elastic switch outside the power box. Since the power box is electrically connected to the alarm, the alarm on the top of the power box will sound, thereby reminding adults far away.

[0016] The utility model is provided with a bicycle body, a seat is fixedly connected to the top of the bicycle body, and a limiting plate is fixedly connected to the outer side of the seat. The child's waist can be protected by the extension plate in the lifting groove inside the limiting plate. When the height of the extension plate needs to be adjusted, the screw is first rotated to rotate and move inside the threaded tube. At this time, the screw will move out of the positioning hole, so that the extension plate can be adjusted inside the lifting groove. At this time, the rod is rotated to make one end of the screw enter the positioning hole again, so that the extension plate inside the lifting groove can be fixed, thereby achieving the effect of being able to adjust the height of the waist protection device.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1 Please refer to Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] A children's bicycle with a stable and anti-collision structure comprises a bicycle body 1, a seat 2 is fixedly connected to the top of the bicycle body 1, an anti-collision alarm mechanism 3 is fixedly connected to the outer side of the bicycle body 1, a waist protection mechanism 4 is fixedly connected to the outer side of the seat 2, the anti-collision alarm mechanism 3 comprises a connecting rod 31, a stabilizing plate 32 is fixedly connected to the outer side of the connecting rod 31, a buffer tube 33 is fixedly connected to the outer side of the stabilizing plate 32, a nylon rod 34 is movably connected to the inside of the buffer tube 33, a force-bearing plate 35 is fixedly connected to the outer side of the nylon rod 34, a shock-absorbing spring 36 is fixedly connected to the outer side of the buffer tube 33, a sponge 37 is fixedly connected to the outer side of the force-bearing plate 35, a connecting rod 38 is fixedly connected to the inner side of the force-bearing plate 35, an extrusion cover 39 is fixedly connected to the outer side of the connecting rod 38, a power box 310 is fixedly connected to the outer side of the stabilizing plate 32, an elastic switch 311 is fixedly connected to the outer side of the power box 310, and an alarm 312 is fixedly connected to the top of the power box 310.

[0026] Specifically, Figure 1 As shown, the stabilizing plate 32 is fixedly connected to the outside of the bicycle body 1 through the connecting rod 31, the buffer tube 33 is symmetrically distributed on the outside of the stabilizing plate 32, the force-bearing plate 35 and the sponge body 37 are located in front of the bicycle body 1, and the end of the shock-absorbing spring 36 away from the buffer tube 33 is fixedly connected to the outside of the force-bearing plate 35. The connecting rod 38 and the extrusion cover 39 are located between the force-bearing plate 35 and the stabilizing plate 32, and the extrusion cover 39 and the elastic switch 311 are on the same plane.

[0027] Specifically, the stabilizing plate 32 is fixedly connected to the front end of the bicycle body 1 through the connecting rod 31, and the force-bearing plate 35 and the sponge 37 are used in combination to provide a preliminary buffering treatment for the impact. The force-bearing plate 35 is subjected to the impact force, so that the connecting rod 38 drives the extrusion cover 39 to squeeze the elastic switch 311.

[0028] In this embodiment: by setting up a bicycle body 1, a connecting rod 31 is fixedly connected to the outside of the bicycle body 1, and a stabilizing plate 32 is fixedly connected to the outside of the bicycle body 1 through the connecting rod 31. When the front end of the bicycle body 1 is impacted, the sponge 37 and the force-bearing plate 35 are used in cooperation to preliminarily buffer the impact force. At this time, the force-bearing plate 35 is moved. Since a shock-absorbing spring 36 is fixedly connected to the outside of the force-bearing plate 35, the impact force is buffered. Then, the nylon rod 34 moves back and forth inside the buffer tube 33, thereby eliminating the generated potential energy. At this time, the connecting rod 38 is driven to move by the movement of the force-bearing plate 35, so that the extrusion cover 39 on the outside of the connecting rod 38 squeezes the elastic switch 311 on the outside of the power box 310. Since the power box 310 is electrically connected to the alarm 312, the alarm 312 on the top of the power box 310 will sound, thereby reminding adults in the distance.

[0030] Specifically, Figure 1-4 As shown, the alarm 312 is electrically connected to the power box 310 , the extension plate 43 is movably connected to the inside of the lifting slot 42 , the positioning holes 46 are evenly distributed inside the extension plate 43 , and one end of the screw 45 is located inside the positioning hole 46 .

[0031] Specifically, when the elastic switch 311 is squeezed, the power box 310 is energized, thereby sounding the alarm 312 to warn the adult, and the screw 45 is located inside the positioning hole 46 to position the extension plate 43 inside the lifting slot 42.

[0032] In the present embodiment: a bicycle body 1 is provided, a seat 2 is fixedly connected to the top of the bicycle body 1, and a limiting plate 41 is fixedly connected to the outer side of the seat 2, and the extension plate 43 in the lifting groove 42 inside the limiting plate 41 can protect the child's waist. When it is necessary to adjust the height of the extension plate 43, first, the screw 45 is rotated to rotate and move inside the threaded tube 44, and the screw 45 is moved out of the positioning hole 46, so that the extension plate 43 is adjusted inside the lifting groove 42. At this time, the screw 45 is rotated again to make one end of the screw 45 enter the positioning hole 46 again, so that the extension plate 43 inside the lifting groove 42 can be fixed, thereby achieving the effect of being able to adjust the height of the waist protection device.
