Abstract

A handlebar folding mechanism comprises an installation base, handlebars and a limiting component and is characterized in that the handlebars are in a hinged connection with the installation base; and the limiting component is located in space which is formed between the handlebars on two sides when the limiting component plays a role in limiting so as to push or pull the handlebars on the two sides. The handlebar folding mechanism provided by the invention has the advantages that the overall width of the folded handlebars is reduced, and thus a constraint factor is removed for the width of a whole folded bicycle.

Description

Handlebar folding mechanism

Technical field

The present invention relates to a kind of handlebar folding mechanism, be specially a kind of bicycle handle bar folding mechanism.

Background technology

The demand of people to folding bicycle is that its volume of requirement is more and more less, and the car load thickness after wherein folding still can't allow consumer satisfaction, and cannot fold very narrow bicycle handle bar is that bicycle cannot continue one of restraining factors reducing folded size.

Summary of the invention

The object of this invention is to provide a kind of handlebar folding mechanism, reduce folding after the width of handlebar assembly, thus provide further space for the folding of vehicle.

To achieve these goals, the invention provides a kind of handlebar folding mechanism, comprise mount pad, handlebar, limit element, it is characterized in that: handlebar is articulated with mount pad, limit element area of space between the handlebar of both sides and both sides handlebar is produced rise thrust or pulling force when playing position-limiting action.

Described handlebar folding mechanism also comprises deflecting bar, and described limit element moves reciprocatingly along the axial direction of deflecting bar.

Described limit element and mount pad hinged, when handlebar launch need spacing time, limit element turns between the handlebar of both sides around hinged axle center.

Described handlebar folding mechanism also comprises elastic element, and the masterpiece that described elastic element produces is used for limit element.

Good effect of the present invention: the handlebar overall width after folding diminishes, and then the width after car load is folded has lacked restraining factors.

Detailed description of the invention

Embodiment 1

As shown in Figure 1, handlebar 42 each side has a handlebar 42, handlebar 42 is hinged with mount pad 41, the end face of one end that handlebar 42 is positioned at inside mount pad 41 produces one piece of special-shaped schistose texture, in the motion process of handlebar 42, this limit, some, schistose texture edge and spacing jacking block 43 come in contact, spacing jacking block 43 head both sides have tapering, bear column rod member below spacing jacking block 43 insert deflecting bar 45 inside and make cliding friction, make spacing jacking block 43 reciprocating along the axis of deflecting bar 45, an extension spring 44 is provided with between spacing jacking block 43 and mount pad 41, extension spring 44 produces pulling force makes spacing jacking block 43 have the trend of upward movement.

Handlebar launches:

As shown in Figure 1 during state, directly overturn both sides handlebar 42, make handlebar 42 toward horizontal motion, the schistose texture of handlebar 42 termination is rotated, and produces the application force that downforce makes spacing jacking block 43 overcome extension spring 44 move downward, to state shown in Fig. 2 spacing jacking block 43.

As Fig. 3, handlebar 42 has moved to level attitude, the schistose texture of both sides constitutes the opening of band tapering, opening section start width is greater than spacing jacking block 43 head width, spacing jacking block 43 is driven upward movement by extension spring 44, until spacing jacking block 43 two sides withstand the schistose texture of handlebar 42 head completely, handlebar 42 is fixed.

Handle bar folding process:

As shown in Figure 4, spacing jacking block 43 bears one handle structure and stretches out beyond mount pad 41 by the groove of mount pad 41 side, downward pressure is applied to described handle arrangement, spacing jacking block 43 is made to move downward lower position, handlebar 42 falls downwards under gravity, after handlebar 42 folds into vertical position, and release handle, the schistose texture of the upper surface of spacing jacking block 43 upwardly handlebar 42, the pulling force that extension spring 44 produces makes handlebar 42 keep folded state.

Embodiment 2

Embodiment two and the difference of embodiment one are that limiting stopper 46 and mount pad 41 are hinged, and as shown in Figure 5, when needing spacing, limiting stopper 46 is toward mount pad 41 interior overturn, and limiting stopper 46 embeds between both sides handlebar 42.What the supporting elastic element of limiting stopper 46 adopted is spring 47.

Claims

1. a handlebar folding mechanism, comprises mount pad, handlebar, limit element, it is characterized in that: handlebar is articulated with mount pad, limit element area of space between the handlebar of both sides and produce both sides handlebar and rise thrust or pulling force when playing position-limiting action.

2. handlebar folding mechanism according to claim 1, is characterized in that: described handlebar folding mechanism also comprises deflecting bar, and described limit element moves reciprocatingly along the axial direction of deflecting bar.

3. handlebar folding mechanism according to claim 1, is characterized in that: described limit element and mount pad hinged, when handlebar launch need spacing time, limit element turns between the handlebar of both sides around hinged axle center.

4. the handlebar folding mechanism according to Claims 2 or 3, is characterized in that: described handlebar folding mechanism also comprises elastic element, and the masterpiece that described elastic element produces is used for limit element.
