Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 5, the child's cycle of the present invention includes a frame 1, a front wheel assembly 2 rotatably disposed at the front portion of the bottom of the frame 1, and a rear wheel assembly 3 rotatably disposed at the rear portion of the bottom of the frame 1.

The front wheel subassembly 2 sets up respectively in the anterior left and right sides in the end of frame 1, thereby children's bicycle still including being used for ordering about the relative frame 1 rotation of front wheel subassembly 2 and make children's bicycle pedal assembly that advances, in this application, pedal assembly corresponds the front wheel subassembly 2 setting of the left and right sides respectively in the left and right sides, and pedal assembly of the left and right sides sets up independently separately, and pedal assembly through the left and right sides drives respectively and corresponds the front wheel subassembly 2 rotation of one side.

The footrest assembly on each side includes a footrest shaft 41 and a footrest 42. The pedal shaft 41 is rotatably provided on the vehicle body frame 1, the front wheel assembly 2 is fixedly provided at one end portion of the pedal shaft 41, and the pedals 42 are rotatably provided at the other end portion of the pedal shaft 41.

Specifically, the pedal shaft 41 includes a first shaft 411, a second shaft 412 and a connecting shaft 413 connected between the first shaft 411 and the second shaft 412, the first shaft 411 and the second shaft 412 are arranged in parallel, and the third shaft 413 can be respectively arranged perpendicular to the first shaft 411 and the second shaft 412 or obliquely intersect the first shaft 411 and the second shaft 412.

The frame 1 includes the bottom support frame 11 that is located the bottom, and bottom support frame 11 sets up respectively in the left and right sides, and in this embodiment, the rear end of the bottom support frame 11 of both sides is fixed to be set up and is formed the U type structure that the opening is preceding together. The front end of the bottom bracket 11 on each side is provided with a shaft hole, and the first shaft 411 is arranged in the shaft hole in a penetrating way and can rotate around the axis line of the first shaft relative to the bottom bracket 11. The front wheel assembly 2 is fixedly arranged at one end part of the first shaft 411 far away from the second shaft 412, and the front wheel assembly 2 is positioned at the outer side of the bottom bracket 11. The pedals 42 are rotatably arranged on the second shaft 412, and the pedals 42 are positioned on the inner side of the bottom bracket 11.

The foot pedal assembly at each side further comprises a foot pedal belt 43, two end parts of the foot pedal belt 43 are respectively and fixedly arranged at the left side and the right side of the foot pedal 42, and a space for placing the feet of the children is arranged between the foot pedal belt 43 and the foot pedal 42. The provision of the tread band 43 serves to secure the feet of the child, preventing the feet of the child from being separated from the tread 42 when the child steps on the tread 42 to move the child's bicycle.

The cycle also includes a bearing 5 disposed between the first shaft 411 and the bottom bracket 11. Specifically, the bearing 5 is located in the shaft hole of the bottom bracket 11, and is sleeved on the first shaft 411. Through the arrangement of the bearing 5, the friction of the pedal shaft 41 relative to the frame 1 during rotation can be reduced, so that the rotation of the pedal shaft 41 is more stable and smooth, and the running of the bicycle is more stable.

In this embodiment, the rear wheel assemblies 3 are respectively disposed at the left and right sides of the frame 1, specifically, the frame 1 further includes a rear wheel support 12, the rear wheel support 12 is a U-shaped structure with a downward opening, and the rear wheel assemblies 3 at the two sides are respectively disposed at a corresponding end portion of the rear wheel support 12.

Rear wheel subassembly 3 of preferred left and right sides is universal wheel subassembly, like this, when children's bicycle marchs, rear wheel subassembly 3 of both sides all can be relative 1 universal rotations of frame, and this makes turning to of children's bicycle easier, can reduce the turning radius when children's bicycle turns simultaneously.

The children's cycle further comprises a seat assembly 6 for seating a child, the seat assembly 6 being arranged on the frame 1, the seat assembly 6 being arranged, in this embodiment, at the rear of the frame 1.

The frame 1 further comprises a grab rail 13 for a child to hold when the child is seated on the seat assembly 6, the grab rail 13 being located in front of the seat assembly 6.

When the left and right feet of the child respectively pedal the pedals 42 on the corresponding side to rotate the front wheel assemblies 2 on the left and right sides at the same rotating speed in the traveling process of the child bicycle, the child bicycle is in a straight-line driving state. When the left and right front wheel assemblies 2 are rotated in the direction a shown in fig. 2, the child bicycle travels straight forward. When the left and right front wheel assemblies 2 are rotated in the direction B shown in fig. 2, the child's bicycle is linearly retreated.

During the linear traveling of the children's bicycle, the pedals 42 on the left and right sides can be located at the same positions in the front-back direction and the height direction, that is, the children can synchronously pedal the pedals 42 on the left and right sides by two feet to enable the children's bicycle to travel. Of course, the pedals 42 on the left and right sides can be located at different positions in the front-back direction and the height direction, that is, the left and right feet of the child can pedal the corresponding pedal 42 back and forth to move the child bicycle.

When the child bicycle needs to turn during the running process, the left and right feet of the child respectively pedal the pedals 42 at different speeds, so that the pedal shafts 41 at the two sides drive the front wheel assembly 2 to rotate at different rotating speeds. If the child bicycle needs to turn right, the rotation speed of the front wheel assembly 2 on the left side is larger than that of the front wheel assembly 2 on the right side by pedaling the pedals 42. Conversely, when the child's bicycle needs to turn left, the rotation speed of the right front wheel assembly 2 is made greater than that of the left front wheel assembly 2 by pedaling the pedals 42.

When the difference between the rotation speeds of the left and right front wheel assemblies 2 is large by pedaling the pedals 42 and the difference exceeds a predetermined value, the child bicycle can be rotated in situ when the rear wheel assembly 3 is a universal wheel assembly.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
