Detailed Description
An exercise device for upper limb trainers to relieve muscle fatigue, which comprises a shell 1, a rack 3, a motor 7 and a spring 10;
the motor 7 is arranged in the shell 1, and the rack 3 penetrates through the shell 1 and can move relative to the shell 1;
the motor 7 is connected with the speed reducer 6, the end part of the speed reducer 6 is provided with a gear 8, and the gear 8 is meshed with the rack 3 penetrating through the shell 1 (the part positioned in the shell 1);
one end of the spring 10 is connected to one end of the rack 3.
The motor 7 is connected with the single chip microcomputer 5, and the single chip microcomputer 5 is connected with a Flexicity sensor 9 used for being connected with the arm of a user.
The other end of the spring 10 is provided with a pull ring for convenient holding by hand.
The present invention will be described in detail below:
the utility model discloses can adopt complete mechanical mode operation, stimulate spring 10 promptly and resume the training, when feeling chicken fatigue, manual control motor 7 is opened (opens the motor and makes its corotation or reversal) for gear 8 drives rack 3 and pops out, avoids user's muscle damage.
Of course, as an extension, an automatic method may also be adopted: the sensor is attached near the most obvious part of biceps brachii muscle during exercise.
The structure of the device is shown in figure 3, the bottom of a shell 1 is connected with four fixing devices 2 through screws, one side of the inside of the shell is connected with a singlechip 5 and a motor 7 as shown in figure 5, the motor 7 is connected with a speed reducer 6, the end part of the speed reducer 6 is provided with a gear 8, the gear 8 is meshed with a rack 3, a hook at the front end of the rack 3 is connected with a spring 10 outside the shell,
the single chip 5 is connected with a Flexiface sensor 9 outside the shell.
When the patient needs to carry out rehabilitation training, the utility model discloses upper limbs muscle recovery unit passes through four fixing device 2 of 1 lower extreme of shell and fixes in a department. Inside devices such as singlechip 5 and motor 7 of being equipped with of shell, Flexiforce sensor 9 comes out through 1 left sides of shell, connects and user's arm department, and user's accessible extension spring tempers the muscle, and when detecting muscle fatigue, the shell is inside to rotate through motor 7 and makes gear 8 drive rack 3 pop out, avoids user's muscle damage.
Specifically, the method comprises the following steps: the automatic control mode is adopted, the fatigue information of the arm is firstly obtained, then the collected information is processed and analyzed, and then the upper limb recovery training is controlled. The user experiences fatigue during rehabilitation, which manifests itself as tremors in the arm muscles. Through the detection of arm muscle tremor, the rehabilitation training of the user can be assisted to avoid secondary injury of the trainer. And the training effectiveness of the user can be judged by detecting the muscle expansion degree, and the optimal training intensity of the user is searched.
That is to say, place Flexiforce sensor device in training person upper limbs muscle department, detection circuitry device integrated installation is in square shell, the shell lower extreme has fixing device to fix on the desktop, there is the opening in the front side, there is connecting plate (rack) to stretch out, connecting spring on connecting plate (rack), there is the Flexiforce sensor in its left side to be used for tying up and detect muscle strength signal at training person's forearm, when detecting muscle fatigue, connecting plate (rack) on the shell can stretch out, reduce training person and exert oneself. That is, the automatic mode can determine the training state of the muscle of the user through the detection of the degree of muscle expansion, and determine the optimal training intensity of the patient through the detection of the degree of muscle expansion of the arm. The Flexiforcesensor is placed at the muscle belly of the target muscle of a user, collected arm muscle expansion force signals are sent to the single chip microcomputer A/D conversion interface after passing through the conversion circuit, and data are sent to the upper computer through serial port communication to complete subsequent data processing and analysis. The muscle tremor condition is used as the muscle fatigue standard, the tremor of the muscle is monitored by adopting a frequency spectrum method, the training of a user is assisted, the extending length of the connecting plate (rack) is adjusted, the elasticity of the spring is changed, and the purpose of avoiding the user from being injured is achieved. Specifically, the method comprises the following steps: the product can be mainly divided into three parts. Firstly, a muscle force measuring platform is built, and the collected muscle force information is processed and analyzed. Firstly, the characteristics of three information sources of myoelectricity, electroencephalogram and muscle force are compared, and the necessity of taking a muscle force signal as a signal source is explained. And then a muscle strength detection platform consisting of a sensor, an amplifying circuit, a single chip microcomputer and an upper computer is built. The pressure generated when the arm muscles expand is collected through a Flexiforcer sensor, the pressure is amplified and then is subjected to A/D conversion through a single chip microcomputer, the pressure is transmitted to an upper computer through serial port communication, Matlab is used for analyzing time domain and frequency domain of the muscle force, the fatigue condition of the muscle is compared under the condition that the arm bears a load, the muscle fatigue characteristic is obtained, and the factors influencing the muscle fatigue are summarized. A new method for determining the optimal training intensity of a user by detecting the degree of expansion of arm muscles is provided. Secondly, a Bayesian normalized BP neural network is applied to predict muscle fatigue. In order to improve the accuracy of predicting muscle fatigue by a gradient descent method neural network, Bayesian normalization back propagation is proposed for improvement. Through the formula derivation of the Bayes normalized neural network, the feasibility and the advantages of the model are explained, and the feasibility of the model is verified through Matlab simulation, so that the muscle fatigue is predicted. That is, the user reaches the effect of tempering the muscle through extension spring, but when user's muscle fatigue reaches the limit, in order to prevent user's muscle damage, add the sensor at user's arm department, detect arm muscle strength signal, when user's muscle is tired, the spring pops out from the shell makes the user no longer exert power. The shell is provided with a fixing device and can be fixed through an adjusting screw; the sensor is a Flexiforcesensor which is connected with a conversion circuit in the shell and transmits detected muscle force signals to the singlechip. The spring is fixed in shell one end, and the spring is hung in the junction, and when the singlechip detected muscle fatigue, the shell was connected out with the spring and is popped out.
Referring to fig. 3, the device is detachable, can exchange springs 10 with different elastic strengths, and is convenient to move.
To sum up, this application can make the rack remove through the adjustment motor when muscle is tired, changes the elasticity of spring, realizes avoiding user's injured purpose.
