Embodiment 2
On the basis of embodiment 1, as shown in figure 5, being removably connected with seat on platform frame body provided in this embodiment
Structure.The chair base structure includes support rod 12 and seat, and 12 lower end of support rod detachably connects with the first folded frame 1
It connects, upper end is connected with seat (not shown).
It should be noted that this platform uses brushless motor two, controlled using intelligent chip, realizes and move ahead, retreat, is left
Right turn has electrodeless variable-speed by the two-dimentional rocking bar control on control box.The application speed can be limited intelligently, make platform safety
Easy to operate, operation is reliable.Battery uses built-in rechargeable type lithium battery, has charging cycle charge and discharge often, electricity
The light-weight feature in pond, exempts from battery maintenance.Detection of obstacles function is met when there are auditory tone cues when retrogressing, advancing, and cooperates intelligence
Mobile phone shows battery capacity.Facilitate trip, and can be product charging with automobile power source.Subsequent controller can stand or sit
On chair.Platform is foldable, has feature small in size, easy to carry
In addition, used in this application is brushless motor, realize that speed control value AD conversion, left and right two is brushless by controller
The output of motor PWM wave, travel speed detection, battery supply voltage real-time monitoring, and number is mutually passed by bluetooth and smart phone APP
According to function.This product platform and common Medical wheelchair realize good hardware interface, realize that old man or disabled person are accessible out
It goes and obtains the real-time treatment of guardian.
Atmel corp's single-chip microcontroller can be used as control chip to carry out power circuit design in hardware aspect, intelligently fill
Electric system, real-time voltage monitoring system reliably protect lithium battery.Two-way voltage signal AD conversion system and two-way PWM
Signal converts seamless output.Motor-drive circuit devises overcurrent and rotation-clogging protection.In software aspects, using modularization programming and
Structured programming.Software real-time is good, has upgrading space.This product structure is simple, user-friendly.
Have superior speed adjusting performance using brushless motor, be mainly manifested in: (can stepless speed regulation) easy to adjust adjusts the speed model
Width is enclosed, low-speed performance is good (detent torque is big, and starting current is small), runs smoothly, low noise is high-efficient.System worked well electricity
Pressure is 36V, and maximum operating currenbt 10A, peak power output is 360W (single-wheel).Brushless motor has electric mechanical band-type brake system
System, it is necessary to there is electric signal to open band-type brake, motor just can be rotated.
Specifically, the application straight forward principle are as follows: when detecting speed signal is to move ahead, and left and right turn signal
When no steering requires, two-way pwm signal pulsewidth is identical, and realizes that two wheel speeds are identical by left and right two-wheeled velocity measuring, and product is
Directly to moving ahead, while travel speed is detected, no more than upper limit value built in speed.Similarly, when speed signal is to retreat, and nothing
When steering requires, upper limit value that platform retreats and the speed that retreats no more than is advanced.It is required when having progress signal and having to turn to
When, PWM generator carries out two-wheel drive PWM pulse-width controlled according to turn signal digital quantity, is less than the revolving speed of a wherein wheel another
The revolving speed of one wheel, to realize steering.And according to the size of turn signal digital quantity, realize the change of turning radius.
The control of product is based on the industrial rocking bar of two dimension, the output of two-way non-contact type Hall linear element.Reliably and without mill
Damage overcomes the problem inaccurate using common potentiometer bring numerical value.Control box can be placed on wheelchair and take on people's handrail
(taking people and having a normal thinking has manipulation ability), is voluntarily controlled by taking people, can also put on wheelchair handle, be controlled by guardian
System.
The part that this product guardian stands or sits, it is foldable, there is wheelchair assistance platform small in size, carries flexibly,
Using extensive.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
