Abstract

The invention provides a bicycle, which can be folded only by one step, also can be unfolded only by one step, and can be automatically locked when unfolded for a cycling state. Two ends of a core shaft of a hinge are provided with flanges, outer rings of the hinge are pressed close to the outer faces of the flanges, and clamping blocks and the outer rings jointly clamp the flanges. When the bicycle is completely unfolded, with the angle rising of the inner faces, the axial sizes of the flanges are increased enough to make axial contact conical faces between the outer rings and the flanges appressed mutually, so that all hinges are sufficiently fastened. By means of longitudinally folding the bicycle, all parts of the whole bicycle are connected with one another by the hinges, and rotate around the axes of the hinges along the longitudinal face of the bicycle to complete folding and unfolding.

Description

Folding bicycle and self-locking hinge thereof

Technical field:

The invention belongs to folding bicycle.

Background technology:

Current folding bicycle, the folding and expansion of full car all needs several steps actions just can complete, and all needs just can ride after manual locking.

Summary of the invention:

Technical matters to be solved by this invention is for above-mentioned prior art present situation, provides a kind of as long as a step action is just collapsible, also as long as a step action is just deployable, and the bicycle of locking voluntarily launching riding condition.

For this reason, the present invention takes longitudinal folding, (being longitudinally working direction and the above-below direction of bicycle). and full car point forward wheel components, rear wheel part, saddle parts and mobile jib parts, tie component, each parts interconnect by hinge respectively.Folding and while launching each parts be to have rotated along the longitudinal surface of bicycle and around hinge axle center, hinge axle center is perpendicular to the longitudinal surface of bicycle.

In order to lock voluntarily the expansion riding condition of bicycle, there is flange at the two ends of the mandrel of described hinge, and the outside of flange is pressed close in the outer ring of hinge, and the contact surface of the two is circular conical surface.Clamp is housed on outer ring, and clamp is pressed close to again the inner face of flange, clamped flanges together with outer ring simultaneously.On the circumferencial direction of the inner face of flange, at relative proper motion car, approach the residing position of clamp while launching and have lift angle, the axial dimension of flange is increased gradually with lift angle.Clamp is fixing by filling on outer ring, the increase of axial dimension can make the axial circular conical surface that contacts of outer ring and flange draw close mutually, while launching completely to bicycle, flange axial dimension has been increased to is enough to make the axial circular conical surface that contacts of outer ring and flange to be close to mutually, each hinge is obtained enough fastening.

For obtaining enough structural strengths, the two ends of each hinge respectively arrange a flange and outer ring, clamp, and certainly, the flange of hinge and outer ring, clamp also can only respectively arrange one, can lock equally hinge.

Bicycle is when launching to ride, and each parts are at grade, needs to make it dislocation when folding in Different Plane.For this reason, when two adjacent components are connected with the mandrel of hinge or outer ring respectively, all will have a suitable angle, two angular dimension equidirectionals are contrary. and like this, during expansion, two angles are cancelled each other, and two parts remain on same plane.When folding, two angle sums are exactly two parts needed angles that misplace. and certainly, for different parts, this angle is different, in specific embodiment below, will provide these angles.

In addition, the junction when rear wheel part and the expansion of saddle parts, is provided with tapered pin and taper hole, in the side of tapered pin and taper hole, is provided with lateral pin hole, is also provided with lateral pin and spring.When bicycle launches completely, tapered pin taper hole is carved and is closed, make rear wheel part and saddle parts in this combination, when taking saddle, people makes this combination close and firm more, the lateral pin hole that now tapered pin and taper hole side arrange just in time overlaps, and lateral pin is ejected to be inserted in lateral pin hole, pins the combination of tapered pin and taper hole, the deployed condition of car is locked and fastening, and cyclist gets off or collides the locking of the deployed condition that can not affect car and fastening.

Tie component has a bending, and when bicycle launches completely, bending is seizing hinge just in time, thereby together with mobile jib parts, forward wheel components is formed firmly and supported.

Accompanying drawing explanation:

Fig. 1 be bicycle launch completely can be when riding schematic diagram, Fig. 2 is the schematic diagram of bicycle while collapsing, Fig. 3 is the schematic diagram of car hinge while collapsing, Fig. 4 is the schematic diagram of car exhibition hinge while opening.

Specific embodiment:

As Fig. 1 Fig. 2: full car divides forward wheel components (12), rear wheel part (21), saddle parts (13) and mobile jib parts (15), tie component (25), and each parts interconnect by hinge (14) (16) (17) (23) (26) respectively.Folding and while launching each parts be to have rotated along the longitudinal surface of bicycle and around hinge axle center, hinge axle center is perpendicular to the longitudinal surface of bicycle.

In order to lock voluntarily the expansion riding condition of bicycle, there is flange (4) at mandrel (3) two ends of described hinge, and the outside of flange (4) is pressed close in the outer ring (1) of hinge, and the contact surface of the two is circular conical surface.Clamp (6) is housed on outer ring (1), clamp (6) is pressed close to again the inner face of flange (4) simultaneously, clamped flanges (4) together with outer ring (1), on the circumferencial direction of the inner face of flange (4), when relative proper motion car approaches expansion, there is lift angle (11) the residing position of clamp (6), the axial dimension of flange (4) is increased gradually with lift angle (11), clamp (6) is fixing by filling on outer ring (1), the increase of axial dimension can make the axial circular conical surface that contacts of outer ring (1) and flange (4) draw close mutually, while launching completely to bicycle, flange (4) axial dimension has been increased to is enough to make the axial circular conical surface that contacts of outer ring (1) and flange (4) to be close to mutually, each hinge is obtained enough fastening.

For obtaining enough structural strengths, the two ends of each hinge respectively arrange a flange (4) and outer ring (1), clamp (6), certainly, the flange of hinge (4) and outer ring (1), clamp (6) also can only respectively arrange one, can lock equally hinge.

Bicycle is when launching to ride, and each parts are at grade, needs to make it dislocation when folding in Different Plane.For this reason, as Fig. 3 Fig. 4: when two adjacent components (7) and (10) are connected with the mandrel (3) of hinge or outer ring (1) respectively, all to there be a suitable angle (8) and (9), two angular dimension equidirectionals are contrary. like this, during expansion, two angles are cancelled each other, and two parts remain on same plane.When folding, two angle sums are exactly two parts needed angles that misplace. certainly, and for different parts, this angle is different, for hinge (14), should not need this two angles, for hinge (16), these two angle sums are 10 ° of left and right, and for hinge (17), these two angle sums are 5 ° of left and right, for hinge (23), these two angle sums are 12 ° of left and right, and for hinge (26), these two angle sums are 2 ° of left and right.

In addition, junction when rear wheel part and the expansion of saddle parts, be provided with tapered pin (24) and taper hole (20), side at tapered pin (24) and taper hole (20) is provided with lateral pin hole, is also provided with lateral pin (18) and spring (19).When bicycle launches completely, tapered pin (24) taper hole (20) is carved and is closed, make rear wheel part and saddle parts in this combination, when taking saddle, people makes this combination close and firm more, the lateral pin hole that now tapered pin (24) and taper hole (20) side arrange just in time overlaps, lateral pin (18) is ejected to be inserted in lateral pin hole, pin the combination of tapered pin and taper hole, the deployed condition of car is locked and fastening, and cyclist gets off or collides the locking of the deployed condition that can not affect car and fastening.

Tie component (25) has a bending (22), when bicycle launches completely, and bending (22) just in time seizing hinge (16), thus together with mobile jib parts, forward wheel components is formed firmly and supported.

To of the present invention, make to be used as an explanation below: as Fig. 1: bicycle is in deployed condition, start to fold, the right hand is held the rear end of hinge (17) and lateral pin (18), when lateral pin (18) is pulled out, the right hand is mentioned, rear wheel part (21) is sagging, while left hand is held handlebar and is drawn close towards the right hand, forward wheel components (12) clockwise rotates around hinge (14), by pull bar (25) and hinge (23), pull rear wheel part (21) to clockwise rotate around hinge (16) simultaneously, saddle parts are at the same time by rotating counterclockwise from recoiling hinge (17), full car collapses into Fig. 2 state.

During expansion, right-hand man is intersected, left hand is held handlebar, the right hand is held saddle, separates both hands when mentioning, and each parts are done rotation contrary when folding, vehicle is deployable, people takes saddle, and each hinge makes the axial circular conical surface that contacts of outer ring (1) and flange (4) be close to mutually under the effect of clamp (6) and lift angle (11), and each hinge is all locked.Now, tapered pin (24) and taper hole (20) are carved and are closed, make rear wheel part and saddle parts in this combination, when taking saddle, people make this in conjunction with more firm, now, the lateral pin hole that tapered pin (24) taper hole (21) side arranges just in time overlaps, and lateral pin (18) is ejected to be inserted in lateral pin hole, the combination of pinning tapered pin and taper hole, the deployed condition of car is locked.
