Description
Technical field
The utility model relates to treadmill field, more particularly, to a kind of device for adjusting treadmill multifreedom motion and
Treadmill.
Background technique
Treadmill is mostly to drive treadbelt to make one passively to run or walk about at different rates by motor.
Six degree of freedom, object have six-freedom degree, the i.e. shifting along x ', three y ', z ' rectangular co-ordinate axis directions in space
Dynamic freedom degree and the rotational freedom around these three reference axis.Any one all has six in space without controlled object
A independent movement.If taking certain constraint measure, the six-freedom degree of object is eliminated, then object is positioned completely.Ginseng
According to Fig. 1, the supporting point of certain rule setting is pressed using six, the principle of constrained body six-freedom degree is known as six point locations original
Reason.
Referring to Fig. 2-4, the prior art generally passes through the rigging position for changing pedestal 101 and front column 102, rear column 103
Relationship realizes the adjustment to 104 angle of treadmill belt, i.e., when needing to be promoted the angle of treadmill belt 104, angular adjustment motor 105
Driving angle adjusts threaded rod 106 and rotates, can band since angular adjustment threaded rod 106 and adjustment seat 107 are threadedly engaged
Dynamic adjustment seat 107 moves upwards, until vertical plate connecting shaft 108 rotates and is upwardly into the front column groove 1010 of top with after
In stake pocket 1011, at the same horizontal sliding axis 109 move to front front vertical plate positioning groove 1012 and back vertical plate positioning it is recessed
It in slot 1013, stops operation, realizes that angle adjusts upward；Angular adjustment motor 105 inverts, and angle can be realized and adjust downwards.
This prior art is equivalent to origin and is located at pedestal 101 and 109 tie point of horizontal sliding axis, is x ' with 101 width direction of pedestal
Axis direction is y ' axis direction with 101 length direction of pedestal, the adjusting of this angle in the prior art, only to x ' axis rotation side
To the i.e. adjusting in one degree of freedom direction cannot achieve multiple degrees of freedom adjusting.
Existing treadmill usually controls the lifting of the treadmill gradient by a lift motor, and the gradient of treadmill is only
There are the adjusting in one degree of freedom, the i.e. angular adjustment of ascents and descents, is unable to rugged road in simulating natural environment
Road road surface.
Training, can only train the tissues such as human muscle, ligament and joint, including brain to exist on existing treadmill
The locomitivity of interior kinesitherapy nerve in one direction.In the natural environment, since road is rugged and rough, the landform on road surface
Include not only upward slope descending, include thes case where each inclined-plane.Human motion tissue and kinesitherapy nerve situation to be treated are wanted
More complicated than existing treadmill slope change is more.The treadmill of existing only two angles of raising and lowering adjustment, human body participate in
The joint of movement and the direction of motion of musculature are fixed and invariable, balanced capacity and flexibility training limitation to human body
It is very big.And if the tissues such as human synovial and muscle can be transferred multiple by so that treadmill is can be realized multiple degrees of freedom adjusting
Movement on direction, to greatly increase the flexible of people, strength, balance, posture and cardio-pulmonary function.
Applicants have discovered that at least there is following technical problem in the prior art:
Adjusting of the gradient of treadmill only in one degree of freedom, the i.e. angular adjustment of ascents and descents, cannot simulate
Rugged pavement of road in natural environment.
