Problems solved by technology

[0002] When children use karts and other vehicles with exposed structures, there are great safety hazards. The angle between some rods is easy to pinch children, especially during the steering process. The steering of the four-wheeled stroller needs to achieve synchronous parallel steering of the front wheels. Generally, the connecting rod structure is used, but the connecting rod structure is very easy to generate the angle between the rods when turning, and it is easy to pinch and shear, which will cause harm to children's safety.
[0003] Therefore, the safety standards for children's vehicles at home and abroad have the requirements of preventing exposed structures such as squeezing and shearing that are easy to injure children's limbs. The general activity gap cannot be in the range of 5-13mm; , in the design of children's vehicles, a structure that completely closes the relevant mechanisms is often used, which costs a lot

Embodiment 2

[0028] The difference from embodiment 1 is that the steering limit structure of this embodiment is located on the operating lever, see image 3 , image 3 A and image 3 B. A limit screw hole 26 is set on the joystick outer sleeve 34, and a limit waist hole 27 is set on the joystick inner sleeve 25, and the left and right steering limit control is performed through the limit screw 28.

Embodiment 3

[0030] The difference from Embodiment 1 is that the steering limit structure is not implemented on the fan-shaped shielding plate, but is implemented on the operating mechanism, that is, the outer tube and inner rod of the operating rod.

[0031] Steering lever 21 also can adopt the curved rod that can adjust length, relies on end bending to avoid dangerous crack or gap, and precisely adjusts steering angle. The steering lever 21 is composed of a curved rod outer sleeve 29 and a curved rod inner sleeve 30. Both ends of the curved rod outer sleeve 29 are equipped with internal threads, and one end of the curved rod inner sleeve 30 is equipped with external threads and the other end is equipped with assembly holes. , after the assembly and connection of the inner casing 30 of the curved rod and the outer casing 29 of the curved rod, the length can be adjusted by using the thread, and the steering lever 21 is assembled and connected with the steering fork 19, thereby completing th...

Abstract

An extrusion-proof and clapping-proof steering structure belongs to the technical field of baby carriages, and comprises two suspension front wheel shafts (18), two steering fork-levers (19), a steering lever (21), a front frame (20) and an extrusion-proof and clapping-proof component; the suspension front wheel shafts (18) and one end of the steering fork-levers (19) are hinged and fixed with two ends of the front frame (20) in the bilateral symmetry manner; the other end of the two steering fork-levers (19) are symmetrically hinged with the left and the right ends of the steering lever (21); a poke groove is arranged in the middle of the steering lever (21); an eccentric shaft which is inserted into the poke groove is controlled by the baby carriage mechanism and can poke the steering lever move to the left and right; the two steering fork-levers (1), the steering lever (21) and the front frame (20) form a link mechanism of a parallelogram; the extrusion-proof and clapping-proof component is filled in a medial angle of the fork-levers and the steering lever; and the minimal medial crevice is larger than 13mm when the parallelogram swings from left to right. The invention guarantees that the exposed structure does not result in extrusion and clapping with a simple structure, fulfills the international toy safety standard, and reduces the manufacture cost.

Description

technical field [0001] The invention belongs to the technical field of children's vehicles, and in particular relates to an orientation structure of a children's vehicle, which is suitable for four-wheeled children's vehicles such as karts with unclosed mechanical structures such as steering transmission. Background technique [0002] When children use karts and other vehicles with exposed structures, there are great safety hazards. The angle between some rods is easy to pinch children, especially during the steering process. The steering of the four-wheeled stroller needs to achieve synchronous parallel steering of the front wheels. Generally, a connecting rod structure is adopted, but when the connecting rod structure is turned, the angle between the rods is likely to be squeezed and sheared, which will cause harm to children's safety. [0003] Therefore, the safety standards for children's vehicles at home and abroad have the requirements of preventing exposed structures ...
