Description

A lower limb health training device

Technical field:

The utility model relates to a lower limb health training device, which belongs to the field of rehabilitation medicine and sports fitness equipment.

Background technique:

The increasing degree of aging society, stroke, spinal cord injury and other reasons lead to the reduction of limb function and movement, or even complete loss, which seriously affects the quality of life. Rehabilitation treatment is an effective way to restore motor function. The traditional one-on-one rehabilitation treatment method between physical therapists and patients has the disadvantages of high labor intensity and high treatment costs. Therefore, rehabilitation training equipment is an effective way to solve this contradiction. Since the middle of the last century, many achievements have been made in rehabilitation training equipment, such as single-degree-of-freedom, exoskeleton, suspension and so on. But they have the following deficiencies: complex operation, single movement form, difficulty in simulating human space movement, inability to adapt to training of various subjects, etc. It has certain practical significance to develop a human lower limb rehabilitation training device that can realize various trajectory movements in the plane .

Utility model content:

In order to overcome the defects of the prior art, the purpose of this utility model is to provide a lower limb health training device with a simple and compact structure, a wide range of applications, and can be used in the rehabilitation and fitness training of the lower limbs.

The utility model solves the technical problem and adopts the following technical solutions:

A lower limb health training device:

The health training device includes a lower limb training machine and an adjustment device, and the adjustment device includes an angle adjustment mechanism and a horizontal motion mechanism that drives the horizontal displacement of the angle adjustment mechanism;

The lower limb training machine is fixed on the cover plate of the angle adjustment mechanism.

The angle adjustment mechanism includes the cover plate, the base plate, and the linear push rod; the cover plate and the base plate are hinged at the bottom edge, one end of the linear push rod is hinged with the middle of the cover plate, and the other One end is hinged with the front edge of the bottom plate to form a four-bar mechanism.

The horizontal motion mechanism includes a motor, a lead screw, a guide rail and a slide block. One end of the lead screw is connected to the output shaft of the motor through a coupling, and the other end is connected to the middle of the slide block to form a spiral pair. The guide rail is used to support and guide the slider; the bottom plate of the angle adjustment mechanism is fixed on the slider.

Compared with the prior art, the beneficial effects of the utility model are reflected in:

The angle adjustment frame includes the rear end of the cover plate and the rear end of the bottom plate hinged to form a rotary pair; one end of the linear push rod is hinged to the middle of the cover plate, and the other end is hinged to the rear end of the bottom plate to form a four-bar mechanism structure, and the linear push rod drives the cover plate to rotate , for the height adjustment of the rehabilitation trainer to adapt to different users.

The utility model can quickly adjust the position of the training machine, because the slider is stuck on the guide rail to form a sliding pair, so that the lower limb rehabilitation training machine can adapt to the distance adjustment of different groups of people and people of different heights.

The utility model can carry out trajectory planning in the vertical plane, and realize the trajectory planning in the vertical plane through the linkage of the training machine, the linear push rod and the motor; it meets the needs of users for different training trajectories and different training ranges.

The utility model has wide application range, various rehabilitation training modes, and can realize active/passive training.

The utility model has a compact and flexible structure, can be retracted freely, occupies a small space, and is applicable to various bodies such as seats, wheelchairs, and beds.

During active training, the utility model can not only be used as a rehabilitation trainer to restore limbs, but also can be used as a fitness apparatus to enhance physical fitness.

Figure 1 is a schematic diagram of the front view of the utility model; Figure 2 is a top view; Figure 3 is a left view.

Labels in the figure: 1 motor, 2 lead screw, 3 guide rail, 4 slider, 5 bottom plate, 6 cover plate, 7 trainer, 8 linear push rod.

The utility model will be further described below through specific embodiments in conjunction with the accompanying drawings.

Detailed ways:

Embodiment: The lower limb health training device of the present utility model: it includes a lower limb training machine and an adjustment device, and the adjustment device includes an angle adjustment mechanism and a horizontal movement mechanism that drives the horizontal displacement of the angle adjustment mechanism.

Referring to the accompanying drawings, the training machine 7 is fixed on the cover plate 6 of the angle adjustment mechanism.

The angle adjustment mechanism includes a cover plate 6, a bottom plate 5, and a linear push rod 8; the bottom edge of the cover plate 6 is hinged to the bottom edge of the bottom plate 5, and the linear push rod is between the facing surfaces of the cover plate and the bottom plate, and the linear push rod One end of 8 is hinged with the middle part of cover plate 6, and the other end is hinged with the front edge portion of base plate 5 to form a four-bar mechanism.

The horizontal motion mechanism includes a motor 1, a screw 2, a guide rail 3 and a slider 4. One end of the screw is connected to the output shaft of the motor 1 through a coupling, and the other end is connected to the middle of the slider 4 to form a spiral pair. The guide rail 3 is used To support and guide the slider 4; the bottom plate 5 of the angle adjustment mechanism is fixed on the slider 4.

In a specific setting, the above-mentioned linear push rod 8 may be driven by electric, hydraulic, pneumatic or other methods, and this embodiment adopts electric drive.

The utility model can be applied to the training and recovery of people whose motor functions of the lower limbs have declined or lost, and helps them easily realize rehabilitation training under various standard motion trajectories. For ordinary people with sound lower limb functions, they can also carry out health training to help them enhance their physical ability.
