The following description of the embodiments of the present utility model will be made with reference to the accompanying drawings and detailed description, wherein it is to be understood that the embodiments described below are merely some, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
In order to improve the convenience of disabled people, a wheelchair ramp design is additionally arranged at the front end of the wheelchair riding device, so that the wheelchair can conveniently go up and down; meanwhile, in order to meet the requirements of various wheelchair models, the front wheels are fixed, the rear wheels are in an open rubber roller fixing design, the umbrella structural design is achieved, the left and right distance adjustment of the transmission shaft 8 is achieved, and the use requirements of wheelchairs of different models are met. In order to facilitate the equipment not to occupy too much space when being used in a home environment, the novel wheelchair riding device is disassembled and designed, so that the novel wheelchair riding device is convenient to install when being used and to decompose when not being used; by designing the transmission mechanism, the product can realize the adjustment of power and resistance under the drive of the low-power motor, thereby assisting the participants in movement; the software control system is designed to realize the control of the torque of the motor so as to achieve the effect of adjusting the motion strength; the data collection, analysis and display system is designed to achieve real-time display of the length of movement, distance, current speed and average speed.
The wheelchair can roll to the parallel track groove 2 through the slope track groove 1 and is fixed manually.
After a user puts the wheelchair on a transmission shaft 8 of the novel wheelchair riding device for driving the wheelchair to rotate, the front wheels are fixed in the parallel track grooves 2 through the front roller baffle 3, so that the stability and safety of the wheelchair are ensured when the user exercises. Then, the motor 7 is started to be switched on and switched off, according to the physical energy level of the user, the user can adjust the physical energy level to a required movement mode and a required difficulty mode through a man-machine interaction interface of an upper computer or a mobile phone APP, the WIFI module transmits data to the raspberry pie, the raspberry pie is processed and then is converted into a motor torque control command, the torque of the motor 7 is adjusted to a target value, so that the movement mode of the wheelchair is changed, and the user can continuously push the wheelchair to move by using both hands to achieve the purpose of exercise, as shown in fig. 4.
Specifically, the function of the wheelchair riding device is divided into three parts, the first part of the wheelchair riding device is composed of a structure, four upright seat bearings 12, parallel track grooves 2 and a motor 7 are fixed on a motor seat 9 by screws, the mode saves the occupied space of equipment, two opposite driving wheels 6 are connected by a transmission shaft 8, and the wheelchair can roll to the parallel track grooves 2 by a slope track groove 1 and is fixed manually.
The second part is a wheelchair power driving device, after the motor 7 receives an instruction transmitted by a data line, the torque of the motor 7 is controlled to be a target value, so that the riding mode of the wheelchair is changed, if the riding mode is a power assisting mode, namely the strength of the upper limb of a user is poor, the driving wheel 6 drives the main wheel of the wheelchair to move, and the auxiliary movement function is realized; in the resistance mode, that is, when the upper limb strength of the user is normal or at a good level, the driving wheel 6 rotates reversely (assuming that the rotation direction of the user is the positive direction), and the effect of exercising the upper limb is achieved.
The third part is a control system, a man-machine interaction interface and a mobile phone terminal APP. The man-machine interaction interface is similar to a mobile phone APP and can display buttons and stop buttons in two working modes, namely a motion mode and a difficulty mode, wherein the motion mode is divided into a power-assisted mode and a resistance mode, and the difficulty mode is divided into a simple mode, a common mode and a difficult mode. The user needs to select whether the movement mode is the assistance or the resistance, then selects the required difficulty mode, does not need to start the control system, and can start the control system by itself only when the user rotates the wheelchair, and the control system automatically matches the corresponding mode according to the direction of the user rotating the wheelchair (different muscle groups exercised in different rotation directions), and the motor stops rotating when the user presses a stop button after training. The mode is adjusted at any time according to the current strength and the physical state, so that the aim of training is fulfilled, the set difficulty mode corresponds to different torque sizes, the torque is transmitted to the raspberry group computer for processing through the WIFI signal, the torque is converted into a motor signal, and then the motor signal is transmitted to the motor through the data line, and real-time control of the motor is realized. The Qt software is used for developing and designing a man-machine interaction interface and a mobile phone terminal APP, controls with different functions such as push buttons, radio buttons and labels are designed, custom controls meeting the requirements are designed by using a signal and slot mechanism, and the functions of selecting a motion mode and displaying speed and distance data are realized. The user can train under the guidance of other people, and the man-machine interaction interface of the upper computer is operated. When the user is alone, the wheelchair can be used for operating by using the mobile phone.
The control system simulates different resistances of different scenes by changing the torque of the motor 7 through torque control, and is designed with a self-starting function; a personal computer interaction interface is designed on the upper computer for display, so that a user can interact with the system through the personal computer interaction interface. The user realizes different operation modes of the controller through the man-machine interaction interface. The modes of the control system comprise a motion mode and a difficulty mode; the sport mode is divided into a booster mode and a resistance mode. When the movement mode is a power-assisted mode, the two driving wheels 6 and the main wheel of the wheelchair rotate in opposite directions, so that the main wheel of the wheelchair is driven to move to play a role in power assistance; when the movement mode is the resistance mode, the two driving wheels 6 and the main wheel of the wheelchair rotate in the same direction, and the main wheel of the wheelchair is prevented from rotating to play a role in resistance. The difficulty mode is divided into three modes of simplicity, common and difficulty, and each mode corresponds to torques with different magnitudes set in a program and plays a role in adjusting the power assistance and the resistance. Meanwhile, the mobile phone APP is designed to be convenient for a user to operate independently, so that the problem that an upper computer is inconvenient to use is solved. The overall workflow diagram is shown in fig. 1.
The control system also comprises a raspberry group computer provided with a ROS (Robot Operating System) system; the self-starting function is that when a user rotates the wheelchair main wheel 6, the system detects that the motor 7 is subjected to friction rotation, and the control program is started automatically; the man-machine interaction interface of the upper computer is developed based on an ROS and Qt (application program development framework) platform, and the display interface comprises options of a movement mode and a difficulty mode, movement duration, wheelchair real-time speed, average speed and riding distance; the interface of the mobile phone APP comprises a stop button, a motion mode and a difficulty mode.
