Embodiment
Referring to figs. 1 to Fig. 3, a kind of full landform compliant wheel of the utility model, including wheel hub 10, wheel rim 20 and radially connected
Four spokes 30 between wheel hub 10 and wheel rim 20, along the circumferential direction equally spaced arrangement, wheel rim 20 are also right for four spokes 30
The head and the tail combination of Ying Yousi sections sectional rim is formed, and every section of sectional rim, which is connected with movable wheel rim 22 by fixing wheel rim 21, to be formed, respectively
Corresponding fixed wheel rim 21 is fixedly connected with the outboard end of spoke 30, and movable wheel rim 22 passes through bearing pin and the outboard end of spoke 30
Portion is hinged, so as to which movable wheel rim 22 can rotate around pin joint so that and fixed wheel rim 21 separates with the movable activity of wheel rim 22, its
In, the fixed end of wheel rim 21 is supported with the movable end of wheel rim 22 to be contacted so that each section of fixed wheel rim 21 is connected with movable wheel rim 22
Circle is kept into, even if that is, movable wheel rim 22 is under the action of the centrifugal force, will not also be moved radially outward the circular wheel beyond wheel
Exterior feature, especially fixed wheel rim 21 and the outside of movable wheel rim 22 are equipped with tire, can guarantee that fixed wheel rim 21 and movable wheel rim 22 it
Between be flexible contact.
Elastic member 40 is also respectively connected between wheel hub 10 and movable wheel rim 22, elastic component 40 can be with elastic telescopic
Mobile, the end of elastic component 40 is supported on movable wheel rim 22, living when running into ground obstacle so as to the movable wheel rim 22
Driving wheel rim 22 can overcome the elastic force of elastic component 40 to be rotated around pin joint to contract, to change the outer table skeleton of wheel,
So that wheel realizes that Multi-contact or face contact with ground, when the movable wheel rim 22 leaves ground, in the bullet of elastic component 40
Property power effect under, movable wheel rim 22, which is displaced outwardly resetting, make it that wheel reverts to circular contour, i.e., sectional rim 20 is completely at oneself
Rounded profile is to maintain under right state.
Wherein, four radial skew of spoke 30 arrangements, the outboard end of each spoke 30 are fixedly connected with fixed wheel rim 21,
The medial end of each spoke 30 is overlapped on the middle part of adjacent spokes 30 so that it is in well shape that four spokes 30, which are connected,.
Preferably, elastic component 40 includes radially fixed pipe fitting 41 in the outside of wheel hub 10, accommodated in pipe fitting 41
Spring 42, and part are sleeved on the inner support rod member 43 of pipe fitting 41, and one end and the spring 42 in pipe fitting 41 of supporting bar 43 are supported
Contact, the other end of supporting bar 43 are flexibly connected with movable wheel rim 22, so as to when movable wheel rim 22 contacts with ground obstacle
When, interference is supported by barrier, supporting bar 43 can overcome the elastic force of spring 42 to move radially inwardly, and movable wheel rim 22 is around hinge
Contact is rotated to contract, to change the outer table skeleton of wheel.Wherein, movable wheel rim 22 radially inside inwardly protruding formation flange
221, the other end of supporting bar 43 forms the groove 431 mutually chimeric with flange 221, when movable wheel rim 22 rotates around pin joint,
Supporting bar 43 moves radially simultaneously, and the groove 431 of the end of supporting bar 43 can slide back and forth along flange 221.
Movable wheel rim 22 around pin joint rotate when, between the other end of movable wheel rim 22 and adjacent spoke formed slide
The relation of mating connection, specifically, four spokes 30 form by the arc spoke 31 of two intervals side by side, two arc spokes 31
Between form chute 32, the other end of movable wheel rim 22, which is stretched out, to be embedded in the chute 32, so as to form sliding connection.
Space between two arc spokes 31 is additionally provided with baffle plate 33, and baffle plate 33 can effectively improve the rigidity of structure of spoke 30, and
And wheel, in the water body environment downward driving such as marsh, mud, radially-arranged baffle plate 33 contacts with water body, can provide certain anti-
To motive force, wheel-slip idle running is avoided the occurrence of.
The full landform compliant wheel of the utility model is adapted to different terrain traveling, for example, when the ground row in big rise and fall
When sailing, when wheel runs into ground obstacle, movable wheel rim can rotate to contract around pin joint, change the appearance wheel of wheel
It is wide so that Multi-contact can be realized between barrier and wheel, provides more contact points for wheel rolling, wheel is easier to cross
Obstacle.When in ground runs such as marsh, mud, movable wheel rim is contacted with ground to the flexible soil body such as contract, marsh, mud
The region inwardly shunk into movable wheel rim, so as to increase Vehicle surface profile and soil body contact area, reduce ground connection
Pressure, moreover, the baffle plate between two arc spokes further increases wheel and contact area of ground, avoid the occurrence of wheel-slip
Idle running.
Embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not limited to
Embodiment is stated, in the technical field those of ordinary skill possessed knowledge, this practicality can also not departed from
Various changes can be made on the premise of new objective.
