Abstract
Description
Technical Field
[0001] The utility model relates to training equipment, in particular to a foot training exercise device, belonging to the technical field of training equipment. Background Art
[0002] Foot training is a common type of training in rehabilitation training. Current foot training generally drives the knee joint to drive the foot linkage, allowing patients to perform leg lifting training, promote blood circulation in the patient's legs, and promote the rehabilitation of the patient's lower limbs. The current equipment lacks an effective way to obtain the patient's lower limb force, making it difficult to judge the patient's force situation, and it is impossible to make an objective evaluation and arrangement of the training process and effect. Many current foot movement devices do not have resistance, and training with power assistance can achieve better results and is a recognized method in rehabilitation training. Currently, power-assisted devices often use electromagnetic resistance, motors applying reverse current to generate resistance, and other modes. The structure is relatively complex, and the training resistance and constant resistance provided during a training stroke. Summary of the invention
[0003] The purpose of the present invention is to overcome the above problems existing in current foot training and to provide a foot training exercise device.
[0004] To achieve the purpose of the utility model, the following technical solutions are adopted: a foot training exercise device, comprising a chassis, two parallel guide rails fixedly connected to the chassis, each guide rail is equipped with a slider, a first bracket fixedly connected to the slider, the inner ring of the first rod end joint bearing is connected to the first bracket through an axis, the rod end of the first joint bearing is fixedly connected to one end of the spring, the rod end of the second rod end joint bearing is fixedly connected to the other end of the spring, the inner ring of the second rod end joint bearing is connected to the second bracket through an axis, the second bracket is fixedly connected to one end of the beam-type weighing sensor, the other end of the beam-type weighing sensor is fixedly connected to the chassis, the length direction of the spring and the guide rail are both horizontal, a vertical mounting block is fixedly connected to the slider, a footrest is fixedly connected to the mounting block, the footrest is rotatably connected to the footrest through an axis, and a foot restraint is fixedly connected to the footrest.
[0005] Furthermore, a laser ranging sensor is installed on the first bracket.
[0006] Furthermore, the lower portion of the mounting block is fixedly connected to a plate, which is fixedly connected to the slider, and a long slit is opened on the chassis, and the plate is located in the long slit.
[0007] The positive and beneficial technical effects of the present utility model are as follows: This exercise device can detect the movement force of the foot, and the spring can provide a certain resistance during movement. The greater the spring is stretched, the greater the resistance it provides. Variable resistance training can be provided during one stroke, improving the training effect, which will be specifically described in detail in combination with the specific embodiments.

[0012] The present utility model will be further explained in detail in combination with the drawings. The marks in the drawings are as follows: 1: Chassis; 2: Plate; 3: Mounting block; 4: Footrest; 5: Shaft; 6: Foot pedal; 7: Foot restraint strap; 8: Long slot; 9: Guide rail; 10: Slide block; 11: First bracket; 12: First rod end joint bearing; 13: Spring; 14: Second rod end joint bearing; 15: Second bracket; 16: Beam type load cell; 17: Laser distance sensor;
[0013] The horizontal and vertical directions in the present utility model are for clearer explanation and do not represent the actual directions during use.
[0014] As shown in the attached drawings, a foot training exercise device includes a chassis 1. Two parallel guide rails 9 are fixedly connected to the chassis. Sliders 10 are fitted on the guide rails. The following components are provided on both sliders: A first bracket 11 is fixedly connected to the slider. The inner ring of a first rod end joint bearing 12 is connected to the first bracket 11 by a shaft. The rod end of the first rod end joint bearing 1 is fixedly connected to one end of a spring 13. The rod end of a second rod end joint bearing 14 is fixedly connected to the other end of the spring. The inner ring of the second rod end joint bearing 14 is connected to a second bracket 15 by a shaft. The second bracket 15 is fixedly connected to one end of a beam type load cell 15. The other end of the beam type load cell 16 is fixedly connected to the chassis. It is defined that the length direction of the spring and that of the guide rail are both horizontal. A vertical plate member 2 is fixedly connected to the slider. A long slot 8 is provided on the box body. The plate member is located in the long slot. The length direction of the long slot is the same as that of the guide rail. An installation block 3 is fixedly connected to the plate member 2. A footrest 4 is fixedly connected to the installation block. A foot pedal 6 is rotatably connected to the footrest by a shaft 5. In this way, the foot pedal can rotate around the shaft to simulate the action of standing on tiptoe. A foot restraint strap 7 is fixedly connected to the foot pedal.
[0015] As a further optimization, a laser distance sensor is installed on the first bracket. The beam type load cell and the laser distance sensor are both connected to a controller.
[0016] In this application, the beam type load cell (which can be calibrated before use) can obtain the pressure of the patient on the left and right foot pedals, and can detect the patient's exertion during the training process. To prevent the spring from breaking during long-term use, an optoelectronic distance sensor is added to the spring lower seat to implement feedback on the distance. The spring force obtained by the load cell and the distance change collected by the optoelectronic distance sensor are used to calculate the stability of the elastic coefficient K through the formula F = k△x. When the spring coefficient K value exceeds the set safety value, the spring needs to be replaced. This improves the safety and stability of the device.
[0017] This device can be used alone or in combination with a lower limb training device. When in use, the foot is restrained by the foot restraint strap. The patient's foot drives the footrest to drive the slider to move. During the movement of the slider, the spring exerts a force on the beam type load cell, and the magnitude of the force on the sole of the foot can be detected. Moreover, the reaction force generated by the spring forms a training resistance, improving the training effect.
[0018] After elaborating on the embodiments of the present invention in detail, those skilled in the art can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent application. Any simple modifications, equivalent changes, and decorations made to the above embodiments based on the technical essence of the present invention all belong to the scope of the technical solution of the present invention, and the present invention is not limited to the embodiments described in the specification either.
