Detailed Description
The present invention will be further described with reference to the accompanying drawings. The utility model provides a gravity turns to children's tricycle, its includes frame 1, and the mid-mounting of frame 1 has seat 2, and the forward-mounted of frame 1 has handlebar 3, its characterized in that: the front end of the frame 1 is hinged with a swing frame 4, the swing frame 4 is arranged in a protruding manner, the bottom of the swing frame 4 is provided with a steering hole 5, a steering frame 6 is rotatably arranged in the steering hole 5 through a hinge shaft 7 in the middle of the steering frame 6, a limiting column 8 is arranged on the steering frame 6 and is placed in a limiting groove 9 on the swing frame 4, a reset spring 10 is arranged between the two ends of the limiting groove 9 and the two sides of the limiting column 8, the reset spring 10 pushes the steering frame 6 to be always in a neutral state, and the two ends of the steering frame 6 are respectively provided with a front wheel 11; the tail of the frame 1 is provided with a tail frame 12, the tail frame 12 is connected with the frame 1 through a rotating seat, the tail frame 12 and the frame 1 can axially rotate for a certain included angle, and the tail end of the tail frame 12 is provided with a rear wheel 13.
The middle part of the bogie 6 is provided with a rotating seat 14, the articulated shaft 7 is arranged on the central point of the rotating seat 14, and the limiting columns 8 are symmetrically distributed on the rotating seat 14.
The top of the rocking frame 4 is provided with a positioning seat 15, the rotating seat 14 is coaxially matched with the positioning seat 15, and the rotating seat 14 is positioned in the positioning seat 15 to rotate.
The rotating seat comprises a fixed tube 16 fixed at the tail part of the frame 1, a positioning groove 17 is arranged on the fixed tube 16, an outer sleeve 18 and an inner insertion tube 19 are arranged on the tail frame 12, an active area 20 is arranged between the outer sleeve 18 and the inner insertion tube 19, the fixed tube 16 is arranged in the active area 20, and a fixing screw passes through a mounting hole on the outer sleeve 18 and then passes through the positioning groove 17 to be connected with a positioning hole on the inner insertion tube 19.
The working principle is as follows: the bassinet in the present case adopts preceding double round, the three wheel structure that falls of back single round because the front wheel is the directive wheel, uses behind the double round, and the front wheel of unilateral has better support nature when it turns to promote its stability that turns to, promote the security of bassinet.
When a user needs to turn, the frame is inclined towards one side needing to turn, the front wheel on the turning side is forced to be stressed and increased by gravity, so that the friction force between the front wheel and the ground is improved, the speed of the front wheel on the turning side is forced to be lower than that of the other side, the bogie deflects around a turning hole of the swing frame by utilizing the speed difference, and finally the turning is realized. In a similar way, in order to keep the contact stability of the rear wheel with the ground when the rear wheel is steered, the tail frame 12 is connected with the frame 1 through the rotating seat, and the tail frame 12 and the frame 1 can axially rotate for a certain included angle.
