Description

Upper Limb Rehabilitation Training Device

Technical field:

The invention relates to a rehabilitation training device, in particular to a patient's upper limb exercise rehabilitation training device.

Background technique:

Hemiplegia, cerebral palsy, and paraplegia often result in varying degrees of disability in the upper limbs, which not only brings inconvenience to the patient's life, but also creates a mental burden. Rehabilitation treatment is a very important promotion factor for patients to recover their daily living ability and return to society. At present, there are many devices to help patients perform upper limb rehabilitation training, but the hand movement of the upper limb training provided by the existing devices is usually only a movement on one plane, or the trainer has a complex structure and high cost, and cannot be used by ordinary patients. For daily training.

Invention content:

The purpose of the present invention is to avoid the disadvantages of the above-mentioned prior art, and provide a simple and compact upper limb rehabilitation training device, which is easy to be grafted on other rehabilitation equipment, has rich hand gestures, can provide multi-dimensional space movement, and is low in cost.

The technical scheme that the present invention solves technical problem adopts is:

The structural feature of the present invention is to comprise a frame, a support plate positioned above the frame;

A longitudinal handle is fixedly connected to the support plate, and a handle is arranged on the upper end of the longitudinal handle;

Between the frame and the support plate, two sets of planar linkages whose motion planes are perpendicular to each other are provided; The other end of the rod is hinged on the support plate;

The two groups of planar linkages share a support rod, one end of the support rod is fixed on the frame, and the other end is connected to the support plate through a spherical pair; a cross hinge is used to connect the connection rod and the support plate.

Structural features of the present invention also are:

Set two synchronous pulleys whose axes are parallel to each other and whose axes are parallel to the movement plane of one of the linkage mechanisms, wherein the crank in the linkage mechanism whose movement plane is parallel to the axis of the synchronous pulley and the corresponding synchronous pulley The transmission is carried out by the bevel gear, and the crank in the other set of connecting rods is directly driven by the corresponding synchronous pulley.

The cross hinge is a hinge shaft set in the shape of a "ten". The "ten" hinge shaft forms a rotary pair with the support fixed on the support plate on one axis, and connects with the connecting shaft on the other axis. The rod forms a rotary joint.

A ball joint is arranged between the connecting rod and the crank.

A return spring is arranged between the upper part of the support rod and the support plate.

A swivel joint is formed between the handle and the longitudinal handle.

Compared with the prior art, the beneficial effects of the present invention are reflected in:

1. The present invention is simple and compact, and can be easily integrated into other rehabilitation equipment.

2. The support plate of the present invention can rotate in two vertical planes, so that the movement forms of the upper limbs are diversified.

3. In the present invention, a rotary pair structure can be arranged between the handle and the longitudinal handle, so that the handle can be held in various postures relative to the body.

4. The present invention can form a spherical pair by setting a ball joint between the connecting rod and the crank, so that the support plate can not only move in two planes within a certain range, which not only increases the movement form, but also reduces the impact on the mechanism. manufacturing precision requirements.

5. In the present invention, by setting a return spring between the upper part of the support rod and the support plate, not only the support plate has the ability to maintain a balanced position, but also the hand movement has a flexible link, which plays a certain protective role.

6. The setting of the bevel gear in the present invention converts the motion on two vertical planes into one plane motion, so that the drive can come from one power source, and the drive mode is simplified.

Detailed ways:

Referring to Fig. 1 and Fig. 2, the device includes a frame 1 and a support plate 2 above the frame 1;

A longitudinal handle 3 is fixedly connected to the support plate 2, and a handle 4 is arranged on the upper end of the longitudinal handle 3;

Between the frame 1 and the support plate 2, two sets of planar linkages whose motion planes are perpendicular to each other are set; The other rod end of 6 is hinged on the support plate 2;

Two groups of planar linkages share a support rod 7, one end of the support rod 7 is fixed on the frame 1, and the other end is connected with the support plate 2 through a spherical pair; a cross hinge is used between the connecting rod 6 and the support plate 2.

Set two synchronous pulleys 8 whose axes are parallel to each other and whose axes are parallel to the movement plane of one of the linkage mechanisms, wherein the crank 5 in the linkage mechanism whose movement plane is parallel to the axis of the synchronous pulley is synchronized with the corresponding set The pulley 8 is driven by the bevel gear 9, and the crank in the other set of linkages is directly driven by the corresponding synchronous pulley.

Referring to Fig. 3, the cross hinge is provided with a "ten" hinge shaft 10 in the form of a "ten". On the other axis, it forms a rotary pair with the connecting rod 6.
