Embodiment
The present invention will be described with reference to the accompanying drawings and examples.
The outstanding feature of the present invention is the steering structure for improving existing short distance walking-replacing tool, is directed to first below
This steering structure is illustrated.
As depicted in figs. 1 and 2, rotating shaft 16-9 has deep groove ball bearing 16-6, bearing by the boss 9-2 location and installations of rotating shaft
Bearing block 16-7 is installed on 16-6, is positioned and is determined at deep groove ball bearing 16-5, rotating shaft by boss 9-3 by bearing block 16-7 boss
Position, which is provided with axle fixture 16-10, rotating shaft 16-9 two ends and is separately installed with pad 16-4 and lock washer 16-3, prevents each zero
Part is loosened, and being respectively equipped with round nut 16-2 outside lock washer 16-3 is fixed.16-1,16-13 points of elastic steel sheet fixture
It is not fixed on bearing block 16-7 and axle fixture 16-10, elastic steel sheet 16-15 passes through trimmer 16-14 through rotating shaft 16-9
It is connected with elastic steel sheet fixture 16-1,16-13.The structure is applied to the instrument of riding being divided into two-part car body, preceding
Part is control direction part, and rear portion is divided into gravity center of human body's pedal part.
The rotation that bearing block 16-7 is arranged on the handlebar of the first half such as bicycle for instrument of riding can drive bearing block
16-7 rotation, and axle fixture 16-10 is affixed to pedal body part, makes fixed；Bearing block 16-'s 7 turns
It is dynamic to drive elastic steel sheet fixture 16-1 to rotate, elastic steel sheet 16-15 is twisted deformation, and elastic steel sheet fixture 16-
13 are mounted on axle fixture 16-10, are fixed, i.e. side deformation only occurs for elastic steel sheet 16-15, and spring
Steel disc 16-15 makes flexible, is or else that can rebound automatically in the case of elasticity when twisting, it is achieved thereby that the machine
The auto-reset function of structure.Ambassador's spring steel plate is crossed in order to avoid windup-degree to follow the string, This structure increases limit function,
Limiting plate 16-8 on bearing block 16-7, when bearing block 16-7 rotates, drives limiting plate 16-8 to move, and axle
Fixture 16-10 is fixed, axle fixture 16-10 is touched when limiting plate 16-8 is moved to after certain angle, so as to stop
Motion prevents spring steel plate 16-15 from failing.
Front frame 4-1 is driven to rotate when handlebar 15 is rotated, front frame 4-1 and Rear frame 4-2 is by steering assembly 16
Connection, steering assembly 16 uses bolt connection, axle fixture 16-10 and Rear frame by bearing block 16-7 and front frame 4-1
4-2 uses bolt connection, steering assembly 16 is integrally formed with vehicle frame, when handlebar drives front frame 4-1 to rotate, front frame 4-
(bearing block 16-7 and elastic steel sheet fixture 16-1 connects to be fixed for 1 torsion drive steering assembly bottom bracket 16-7 rotation
Connect) so as to drive elastic steel sheet 16-15 to twist deformation, and spring steel plate 16-15 make it is flexible, when twisting again
It can automatically be rebounded in the case of not following the string, then the bearing block 16- in steering assembly 16 is driven when elastic steel sheet 16-15 rebounds
7 set back, and bearing block drives vehicle frame forward part 4-1 to set back, so as to realize stability of the car body in turning.Whole mistake
Journey, Rear frame 4-2 makes steady motionless, and the inclination of handlebar drives front frame 4-1 inclination, make integral body in turning flexibly from
Such as, while also reducing radius of turn.
The three-wheel short distance walking-replacing tool that the present embodiment is provided, except with good turning function, stability is safe
Outside, it can also be folded in handlebar, vehicle seat, trailing wheel, pedal many places, the boot of automobile can be put into after folding, makes whole vehicle body
Structure is more compact and flexible, is convenient for carrying；Can flexibly it be shuttled in small space in traveling.Car body many places are folded below and carried out in detail
Describe in detail bright.
As shown in fig. 6, the oscillating bar assembly 3 that vehicle seat 2 is made up of four swing rods altogether realizes the positioning of state in figure, and pass through four
Individual positioning hole is attached with Screw, every swing rod is rotated relative to positioning hole, and four swing rods are parallel to each other installation,
Car body both sides are illustrated by taking Fig. 6 visual angles as an example here into symmetrical structure, and swing rod 17 is parallel with swing rod 18 to be installed, for connecting
Front frame 4-1 and vehicle seat 2, swing rod side are fixed on front frame 4-1 by Screw 1, opposite side Screw and vehicle seat 2
It is hinged, the parallelogram sturcutre constituted using two swing rods makes vehicle seat 2 be rotated relative to front frame 4-1, due to pendulum
Bar 17 is designed with swing rod 18 for symmetrical expression, when oscillating bar assembly 3 is moved to such as figure position, and swing rod 18 reaches pole by the limitation of swing rod 17
Extreme position, but due to the mechanical feature on parallel four side, swing rod can only achieve the position and can not move, therefore vehicle seat 2 is extensible
So far without sliding, it is achieved thereby that the positioning of vehicle seat 2.
As shown in Fig. 7 to Figure 11, pedal 5 is fixedly connected with articulated elements 6, and pedal mounting seat 7 and Rear frame 4-2, which is fixed, to be connected
Connect,
Articulated elements 6 is hinged with pedal mounting seat 7 by Screw, allows pedal 5 relative to pedal mounting seat 7
Rotate, realize folding of the pedal relative to Rear frame 4-2, when pedal horizontal deploys, the confined planes 20 of articulated elements 6 pass through pedal
The confined planes 19 of mounting seat 7 are supported, to realize the horizontal location for keeping pedal 5.
Trailing wheel employs folding design, and referring to Figure 10, trailing wheel 11 is connected by trailing wheel mounting bracket 10 with oscillating rod 9,
Trailing wheel mounting bracket 10 is connected with oscillating rod 9 by articulated manner, it is possible to achieve mutually rotated, and oscillating rod 9 and Rear frame 4-2 leads to
Cross copper sheathing 14 to be fixedly connected, swing rod 9 is mutually rotated relative to Rear frame 4-2, two oscillating rods 9 apply parallel four side
Shape mechanical feature makes trailing wheel 11 realize folding switching, when trailing wheel 11 opens in order to fix the position of trailing wheel 11, pacifies on pedal 5
Equipped with pedal rear wheel bar supporting pad 12, pedal rear wheel bar supporting pad 12 is into "convex" shaped shape, and type top half is embedded in two pendulum
Between lever 9, to ensure the position of trailing wheel, make car two smooth-rides of trailing wheel 11 in the process of moving.
Handlebar uses folding handlebar, and handlebar 15 is arranged in handlebar mounting hole 13, the folding of handlebar 15 when folding the car
It is folded, such as Figure 12, ride the car when handlebar 15 expansion such as Fig. 3.
