Description
Technical field
It the utility model is related to a kind of bicycle quick, and in particular to a kind of foldable bicycle wheel.
Background technology
Walking-replacing tool of the bicycle as people, it is more environmentally friendly, it is not take up space, but traditional this body of bicycle
Product is larger, it has not been convenient to carries and transport, people are directed to standard bicycle produced problem, it has been developed that it is folding voluntarily
Car, its folding mode mainly have two kinds, and one kind is that vehicle frame is folded, and vehicle frame folding is divided into vehicle frame doubling again and vehicle frame shrinks
Fold, vehicle frame doubling is mainly the folding carried out to the bicycle with big wheel, but the cycle frame with big wheel
The volume of bicycle is still bigger after folding, is still inconvenient to carry；It is less voluntarily for wheel that vehicle frame, which shrinks folding,
The folding that car is carried out, and wheel is smaller, the volume after folding is smaller, but relative, and wheel is smaller, adapts to the ability on road surface just
It is poorer, run into rough ground and be also easy to overturn；Another kind is that wheel is folded, and the folding to wheel is main in the prior art
It is by the way that rim of vehicle wheel is segmented, then controls wheel rim attachment means manually and apply pressure to wheel, shrink wheel
It is folded into class rugby ball shape or from rounded constrictions to elliptical shape, but this folding to wheel is needed manually by wheel rim
Snib be pulled to foldable pattern or manually unclamp wheel on locker, then to wheel apply pressure carry out wheel folding
Folded, this mode for folding wheel not only easily makes the hand of user dirty, it is also necessary to applies certain pressure to manpower wheel
The folding of wheel is carried out, use is more troublesome.
Utility model content
For the technical problem in the presence of prior art, the utility model, which provides one kind, will not make user's hand dirty
And a kind of folding type vehicle with electric foldable wheel mechanism that pressure can be carried out wheel folding need not be applied to wheel
Wheel.
To achieve the above object, the utility model employs following technical scheme：
A kind of collapsible wheel, including rubber tyre, wheel hub, some spokes, axletree, the rubber tyre and the wheel hub
Be fixedly connected, be provided with stretch-proof body in the rubber tyre, the spoke is divided into king spoke and elongated spoke, if the wheel hub by
The inclined-plane at dry section segment and king spoke both ends is end to end to form a circular hub, and it is fan-shaped that the segment is divided into first
Body, the second segment, the 3rd segment, four fan-shaped body, each segment in pairs and are centrosymmetric setting on axletree, described
Elongated spoke one end is rotatablely connected with king spoke, and the other end and the 3rd segment are rotatablely connected, and the king spoke both ends are slided respectively
It is dynamic that first segment is installed, and the king spoke is provided with the inclined-plane to match with first segment；The king spoke
It is provided with and folds motor, screw rod is provided with the king spoke, described screw rod one end is connected with folding motor and being engaged by gear, separately
One end is connected with the first segment in king spoke by screw thread；The elongated spoke is set to telescopic or rotary type.
When folding wheel, to motor forward voltage is folded, fold motor and rotate forward, the gear wheel folded on motor drives spiral shell
Bar rotate, two first segments at king spoke both ends are displaced outwardly respectively, in the presence of rubber tyre, wheel from circle to
Ellipticity changes；When opening folding wheel, give and fold motor backward voltage, fold motor reversal, fold the gear wheel on motor
Screw rod is driven to rotate, two first segments at king spoke both ends move into king spoke respectively, in the presence of rubber tyre,
Wheel is changed from ellipse to round shape, ultimately becomes a circle.Collapsible wheel in the utility model uses motor driven
First segment is to moving outside king spoke, and the first segment when moving outside king spoke to will drive other on wheel hub fan-shaped
The movement of body, wheel is folded from circle to ellipse, reduce wheel volume after folding, it is not necessary to people's manual unlocking wheel lock
Tight device or snib, it is not required that manpower manual applies pressure to wheel and folds wheel, will not only make user's hand dirty, simultaneously
It need to only open or close and fold motor and can complete folding to wheel, use is more convenient.
Further, the king spoke both ends are respectively equipped with the projection of two hump shapes, are provided between described two projections
The inclined-plane to match with the first segment；The outside side of the projection is provided with the inclined-plane to match with second segment；
The first segment upper end both sides are provided with projection, and second segment is provided with breach, first segment and described the
Two segments are connected by projection with breach；Convex surface and concave surface are respectively equipped with 3rd segment, four fan-shaped body, it is described
It is connected between second segment, the 3rd segment, four fan-shaped body by the convex surface with concave surface.
, there are the inclined-plane coordinated with the second segment, each sector in the existing inclined-plane to match with the first segment of king spoke again
Agreed between body by male and female face, the structure of wheel hub is more agreed with, improve the intensity of wheel when in use, also
Structure is simplified, makes the structure of wheel hub simpler.
Further, each segment is provided with the tire groove to match with the inner peripheral surface of rubber tyre.
Further, the rubber tyre is provided with tire lockhole, and hollow shaft, each segment are provided with the tire lockhole
It is provided with the segment lockhole corresponding with the tire lockhole.
When mounted, solid shafting is through the hollow shaft in the segment lockhole and rubber tyre in segment, by rubber wheel
Tire is riveted in the tire groove of each segment, due to the pore size of the hollow shaft in tire lockhole and the pore size of segment
Equally, solid shafting will pass through hollow shaft riveting of the segment lockhole simultaneously and in tire lockhole, so the sky set in tire lockhole
Mandrel picture root pillar props up the tire trough rim of each segment, therefore improves the intensity of each segment.
Further, each segment appearance has rubber covering.
Each segment appearance sets rubber to cover, and is the road when in use in order to improve the seal of each segment interface
Sandstone on face will not enter segment interface.
Further, the stretch-proof body is set to one group of closed shape and matched with the shape of the rubber tyre.
Two groups of symmetrical stretch-proof bodies are provided with wheel in the prior art, but the stretch-proof body being segmented is being processed
Complex during manufacture, stretch-proof body is arranged to one group of closed shape by the utility model, and is matched with the shape of rubber tyre,
Such stretch-proof body technique in processing is simple, and more convenient during installation.
Compared to prior art, folding bicycle of the present utility model can carry out wheel folding by motor, it is not necessary to
Hand foldable wheel, use is more convenient, and the use intensity raising of wheel hub, structure are simpler, and the intensity of each segment improves,
The seal of interface is more preferable, and technique when stretch-proof body is processed is simpler, easy for installation.
