Abstract

The invention provides a thrust mechanism of a supporting tube of a semi-automatic folding moped, which can realize automatic folding, saves labor and can be rapidly and conveniently used. The invention is characterized by comprising a handle, a switch and the supporting tube, wherein the handle is installed on a main bearing base, the switch is in electrical control connection with a thrustor, the supporting tube is positioned within the maximum pushing stroke of the push rod of the thrustor, the lower end of the supporting tube supports a rear fork, and a through hole in which the supporting tube can slide up and down is arranged at the part, which is positioned within the maximum pushing stroke of the push rod of the thrustor, in the rear fork.

Description

A kind of thrust mechanism of supporting tube of semi-automatic folding moped

(1) technical field

The present invention relates to the morpet technical field, be specially a kind of thrust mechanism of supporting tube of semi-automatic folding moped.

(2) background technology

Existing folding bicycle, it comprises vehicle frame, assembly, front-wheel, the trailing wheel with expansion and folder function, the electric-control system that is arranged on the saddle on the vehicle frame and drives front-wheel or trailing wheel.For the ease of carrying, reduce storage space, existing folding bicycle, its vehicle frame adopts one or more foldable structure, realizes folder function, is to pull pine or fastening through manual operation but fold, relatively effort, very inconvenience.

(3) summary of the invention

To above-mentioned technological deficiency, the invention provides a kind of thrust mechanism of supporting tube of semi-automatic folding moped, it can realize auto-folder, uses laborsaving, quick and easy.

Its technical scheme is such: it is characterized in that: it comprises handle, switch; Said handle is installed on the primary load bearing seat; Said switch and thruster electricly connect; Support tube is positioned at the maximum stroke that promotes of push rod of thruster, and the lower end of support tube is supported in the back chain stay, and the maximum position that promotes in the stroke of the push rod that is in thruster in the back chain stay is provided with and can holds the through hole that support tube slides up and down;

It is further characterized in that: said switch is installed on the side-lower of said handle, and the bottom of said handle contacts with switch in rotation; Said switch is installed on the position of controlling of said handle.

After the present invention adopted said structure, handle was through switch control thruster, and thruster control support tube can realize that like this power-assist of battery-driven car is folding, and is quick, convenient; Just need not launch by foot's strength, safe and reliable, quick and easy.

Fig. 2 is in the structural representation of folded state for using boosted vehicle of the present invention;

Fig. 3 is a textural association scheme drawing of the present invention.

(5) specific embodiment

See Fig. 3, the present invention includes handle 8, handle 8 is installed on primary load bearing seat 20; The side-lower of handle 8 is provided with switch 9; The bottom of handle 8 contacts with switch 9 in rotation, and switch 9 electricly connects with thruster 15, and support tube 14 is positioned at the maximum stroke that promotes of push rod of thruster 15; The lower end of support tube 14 is supported in back chain stay 17, and the maximum position that promotes in the stroke of the push rod that is in thruster 15 of back chain stay 17 is provided with and can holds the through hole that support tube 14 slides up and down; This is the embodiment 1 of thrust mechanism (among Fig. 1, Fig. 2, through hole is covered by primary load bearing seat 20).

The another kind of structure of the thrust mechanism of support tube 14 is exactly that the position of controlling of handle 8 is provided with switch 9 and (does not express among Fig. 1; Mention handle 8 like this; Can realize action to switch 9), switch 9 electricly connects with thruster 15, and is identical among other structures and the embodiment 1.

When vehicle frame by deployed condition when rugosity is changed, angle of inclination handle 8 receives the power of putting forward, (handle 8 is installed on primary load bearing seat 20 through the return torsion spring to overcome the application force of return torsion spring; Inclination certain angle during installation, in order that the switch 9 of control sidepiece, if switch 9 is installed on the position of controlling of handle 8; Then normal mounting just can), utilize the stressed principle of single-point fixed vertical, handle 8 is whole to rotate around attachment points; The punching press shape face of 8 lower end side of shaking hands can be oppressed the switch 9 that is fitted on the primary load bearing seat 20 and touched slide bar, makes its conducting, gives thruster 15 working signals that are arranged on the chain stay 17 of back; Strut bar 14 is withstood in the parallel release of thruster 15 inner core push rod fast speedes, forces strut bar 14 and back chain stay 17 acting point to break away from; When handle 8 stressed transmissions are perpendicular to the ground; Strut bar 14 has broken away from back chain stay 17, and stay tube 12 is along the parallel obliquely downslide of the sleeve pipe 26 of primary load bearing seat 20 in the companion, and last strut bar 14 stretches into the 12b of spacing hole and realizes folding vehicle frame;

Meanwhile; Other parts of whole vehicle frame, with shake hands 8 with primary load bearing seat 20 places of being rotationally connected be fulcrum, the boxed rod 6 in the four-bar linkage structure, lower link 7 rotate respectively and between the preceding Connection Block 3, primary load bearing seat 20; The free end of pipe box 24, bar 23 progressively separates in the decoupling rod; Decoupling rod length overall lengthening, vertical distance dwindles until two bars almost to press close between boxed rod, the lower link, and front fork 2, preceding standpipe 4, handlebar 5 and front-wheel 1 lean on to trailing wheel; And flexible power-assisted pull bar 22 chain stay 17 after jack-up under the lower link that rotates 7 promotions; Back, the back chain stay 17 edge chain stay 17 and the place of being rotationally connected of primary load bearing seat 20 are rotated along clockwise direction; Trailing wheel 18 to front-wheel near; Withstand the lower surface (see figure 2) of the leading section of back chain stay 17 until locating part 13-2, thereby realized the folding and locking of vehicle frame.Whole folding process fast, conveniently.

Among the present invention, thruster 15 genus market existing procucts.Among Fig. 1, Fig. 2, front-wheel 1, front fork 2, preceding standpipe 4, handlebar 5, boxed rod 6, lower link 7, saddle pipe 10, first shackle member 11, middle stay tube 12, second shackle member 13, strut member 13-1, locating part 13-2, battery 16, trailing wheel 18,

microcontroller

19,21 switches, flexible power-assisted pull bar 22, motor 23, pipe box 24, saddle 25, the 12b of spacing hole, locating part 12a.
