Abstract
The invention discloses a hexagonal one-way wheel carrier, which is a wheel of stair climbing vehicles, stair climbing wheelchairs or obstacle crossing vehicles. The hexagonal one-way wheel carrier structurally comprises one-way wheels 1, a wheel carrier (hexagonal star carrier) 2 and pin shaft assemblies 3, the wheel carrier is also known as a hexagonal star carrier and is formed by drilling a central slotted hole and one-way wheel slotted holes in an approximately hexagonal plate. The principle is that the hexagonal star carrier (2) does not revolve and two one-way wheels rotate to realize forward movement when the wheel carrier travels on flat ground, the one-way wheels (1) rotate to a step, then the rotation of the one-way wheels (1) is obstructed, the hexagonal star carrier (2) revolves to roll over onto the step, and the one-way wheels (1) then rotate when the wheel carrier climbs the step, the two one-way wheels (1) are firstly landed, the one-way wheels (1) rotate until one one-way wheel (1) is suspended, then the hexagonal star carrier (2) revolves until the suspending wheel is landed, the center of gravity of the hexagonal star carrier (2) tilts forwards, the hexagonal star carrier (2) continuously revolves until the two one-way wheels (1) are landed, and the one-way wheels (1) rotate until one one-way wheel (1) is suspended when the wheel carrier goes downstairs.
Description
One, affiliated technical field
The present invention's " six unidirectional wheel carriers " is a kind of wheel assembly, can be used as the wheel of upstairs going cart, stair-climbing wheel chair and barrier-exceeding vehicle.Device is mainly comprised of " hexagram frame " and " one-way wheel ", can realize the revolution of hexagram frame and one-way wheel rotation.
Two, background technology:
1 the present invention's " unidirectional six wheel carriers " technical characterictic:
A: wheel carrier (hexagram frame)---shape is as twist drill centre bore and the omni-directional wheel hole of Magen David, and wheel carrier can single, doublely be arranged.
B: one-way wheel.
A+B: one-way wheel is assemblied in respectively six angles of hexagram frame by bearing pin assembly.
2 existing similar techniques:
At present, the stair-climbing wheel chair product being comprised of multi-corner star-shape frame and one-way wheel has a lot, is respectively three unidirectional wheel carriers, four unidirectional wheel carriers, five unidirectional wheel carriers.
2.1 stair-climbing wheel chairs for disabled persons, its technical characterictic A1 '+B, triangle starframe and one-way wheel combination.
Advantage: while climbing building, can realize the revolution of triangle starframe and one-way wheel rotation and automatically switch.
Shortcoming: in the time of downstairs, wheel carrier is turned over suddenly, easily causes concussion.
Referring to Intellectual Property in China net: proprietary term " stair-climbing wheel chair for disabled persons ", number of patent application CN201210330871.0.
2.2 four-wheels " stair-climbing wheel chair ", its technical characterictic A2 '+B, four jiaos of starframes and one-way wheel combination.
Advantage: while climbing building, can realize four jiaos of starframe revolution and one-way wheel rotation and automatically switch.
Shortcoming: in the time of downstairs, wheel carrier is turned over suddenly, easily causes concussion.
Referring to Intellectual Property in China net: proprietary term " stair-climbing wheel chair ", number of patent application CN201120194189.4.
2.3 5 take turns " stair-climbing wheel chair " its technical characterictic A3 '+B, pentalpha frame and one-way wheel combination.
Advantage: while climbing building, can realize the revolution of pentalpha frame and one-way wheel rotation and automatically switch.In the time of downstairs, move smooth and easy.
Shortcoming: when poor hour of stair or shoulder height, wheel carrier was turned over suddenly, easily causes concussion.
Referring to Intellectual Property in China net: proprietary term " stair-climbing wheel chair ", number of patent application: CN200910041584.6.
Three, summary of the invention:
1 technical problem solving:
The automatic switchover of wheel carrier revolution and one-way wheel rotation when realizing cat ladder, and further reduce the concussion that wheel carrier is turned over and brought, hereby apply for " unidirectional six wheel carriers " patent.
2 technical schemes of implementing:
2.1 concrete structures:
One-way wheel on six angles of hexagram frame each one, by bearing pin assembly, be arranged on hexagram frame hole, hexagram frame can be single, double row.One-way wheel is common roller, can only realize one-directional rotation.Hexagram frame is formed by similar hexagonal twist drill centre bore, one-way wheel hole.Bearing pin assembly comprise bearing pin uh groan nut.
2.2 practical functions:
Wheel carrier can automatic turning when running into step, and one-way wheel can roll in the single direction of level.
3 beneficial effects:
(1) simple in structure, only there are two critical pieces.
(2) powerful, can realize the switching of the revolution of hexagram frame and rotation, also can stable action to lower step.
(3) cost economic, one-way wheel is ordinary wheel, and hexagram frame is also convenient to processing.
Four, accompanying drawing explanation:
The unidirectional wheel carrier of Fig. 1 six (single) front view.
The unidirectional wheel carrier of Fig. 2 six (single) axonometric drawing.
The unidirectional wheel carrier of Fig. 3 six (double) front view.
The unidirectional wheel carrier of Fig. 4 six (double) axonometric drawing.
In figure: 1 is unidirectional, 2 wheel carriers (hexagram frame), 3 bearing pin assemblies.Bearing pin assembly (3) is comprised of bearing pin (3.1), bearing pin nut (3.2).
Five, the specific embodiment:
Fig. 1, Fig. 2, Fig. 3, Fig. 4:
1 concrete structure: one-way wheel (1) is arranged on respectively each angle of hexagram frame (2) by bearing pin assembly (3), hexagram frame (2) is drilled with center slotted eye and one-way wheel hole.
2 operation principles:
While putting down away, hexagram frame (2) does not revolve round the sun, two one-way wheels (1) rotation, and realization moves forward.
During cat ladder, one-way wheel (1) certainly goes to and approaches step, and one-way wheel (1) rotation is afterwards obstructed, and hexagram frame (2) revolution, rolls up step, omni-directional wheel (1) rotation again
In the time of downstairs, originally two one-way wheels (1) land, it is unsettled that one-way wheel (1) goes to an one-way wheel (1) certainly, hexagram frame (2) revolution afterwards to unsettled wheel lands, hexagram frame (2) center of gravity leans forward, and hexagram frame (2) continues revolution to two one-way wheels (1) and lands.
Claims (1)
1. " six unidirectional wheel carriers " claim:
Totally 1 of claim, wherein independent claims are 1,0 of dependent claims.
Independent claims:
A: wheel carrier (hexagram frame)---shape is as twist drill center slotted eye and the omni-directional wheel slotted eye of Magen David, and wheel carrier can be single and double.
B: one-way wheel.
A+B: one-way wheel is assemblied in respectively each angle of hexagram frame by bearing pin assembly.
