A kind of gait rehabilitation robot for realizing walking foot pose
Technical field
The present invention relates to a kind of robots in rehabilitation medical instrument field, and in particular to one kind can be realized people in normal row
The gait rehabilitation robot of foot pose when walking.
Background technique
Cerebral apoplexy is a kind of world wide disease of high incidence, its presence has seriously affected the life of the mankind and has been good for
Health.Cerebral apoplexy has a serious impact walking function, have analysis shows, the cerebral apoplexy survivor close to 2/3 will lose walking
Ability.Therefore, walking ability is recaptured, the key link that standing balance function is patients with cerebral apoplexy rehabilitation is restored.Through clinic
Studies have shown that repeating and illness can be effectively relieved in accurate rehabilitation training.For this target, the developed countries such as America and Europe are developed
Lokomat, the robots such as ALEX, LOPES, to help patient to complete rehabilitation training are gone out.However, such robot system is multiple
Miscellaneous, cost is high, and general family is difficult to undertake the medical expense of great number, and such equipment is chiefly used in recovery centre, patient exercise
Limited time, effect are difficult to be guaranteed.Therefore, it is necessary to develop a kind of small-sized, home-use lower limb rehabilitation robot.
By the retrieval discovery to existing technical literature, China Patent No. 201410073019.9 discloses a kind of " household
Small-sized lower limb rehabilitation exercising machine people ", the robot can generate a kind of class elliptical orbit similar with body gait, but with
Normal gait has larger difference.China Patent No. 201210277695.9 discloses " a kind of moving by bondage foot and shank band
Carry out the device of gait training " motion profile for being closer to normal gait is generated by planar linkage combined mechanism, but fail
Realize foot gesture when walking.China Patent No. 201110160875.4 discloses " pedal gait rehabilitation trainer phalanx
The rehabilitation institution in joint ", the mechanism have a driving capability of thigh, shank, ankle and phalanx, but and people in normal walking
Posture still has bigger difference.U.S. Patent number WO2013033855A3 discloses " Gait training apparatus for
Generating a natural gait pattern ", which can be good at realizing normal foot pose, but still need to
The complicated control system of design realizes robot speed's control.
Summary of the invention
The present invention In view of the above shortcomings of the prior art, provides a kind of gait rehabilitation for realizing walking foot pose
Robot.According to the target foot pose that the physical trait of patient and the design of rehabilitation teacher, design match with patient, make
It can be designed that the healing robot mechanism for particular patient or specific objective group with the present invention, driven and suffered from by robot
Person's foot is further driven to patient's lower limb and completes corresponding rehabilitation training.It is a feature of the present invention that mechanism of the present invention can be accurately real
Existing foot pose of the people in normal walking, and only need that robot speed's control can be completed using uniform speed electric motor, thus manufacture
It is at low cost, control system is simple, can satisfy general family's use demand.
In order to solve the above technical problems, a kind of gait rehabilitation robot for realizing walking foot pose proposed by the present invention,

Frame, which corresponds, to be connected;Every set end effector mechanism includes track generating unit and posture control unit;The track occurs single
Member includes the first crank successively driven by the transmission device, the rotation grooved cam being arranged on first crank and installation
The first cam bawl in the rotation grooved cam, one end of first cam bawl and a push rod is hinged, the push rod
The other end be fixed with sliding block, the sliding block interacts cooperation with the sliding slot being fixed on the fixed frame, and the sliding block is successively
It is hinged with first connecting rod, second connecting rod, third connecting rod and the first swing rod, the second connecting rod is cut with scissors with first crank simultaneously
It connects;The posture control unit includes the second crank driven by the transmission device, is set with second on second crank
Cam bawl, the fixed frame are equipped with fixed grooved cam, and second cam bawl is inlaid in the fixed grooved cam, institute
It states the second cam bawl and is hinged with a guide block, the guide block is successively hinged with fourth link, the second swing rod, the 5th connecting rod and steps on
Plate;The guide block slides on second crank under the drive of second cam bawl;Second swing rod with it is described
First swing rod and the third connecting rod are articulated with a hinge joint simultaneously;The pedal is hinged with the third connecting rod simultaneously;Left and right
The first crank or the second crank in the end effector mechanism of two sets of side are installed accordingly with 180 ° of phase differences;The transmission device will
The power of power device passes to the first crank and the second crank simultaneously.
The present invention has the advantages that lower limb rehabilitation robot mechanism of the present invention can generate compared with the prior art
Normal human's gait track, while can be realized foot gesture of the people in normal walking, overcoming the prior art cannot be accurate
Realize the deficiency of foot pose of the people in normal walking.In addition, the present invention need to only use a uniform speed electric motor to carry out robot
Speed control simplifies robot control system, reduces manufacturing cost, and then is suitable for general family and uses.Compared with ectoskeleton
For robot, the present invention relieves constraint of the robot to patient legs, and comfort is more preferably.
