Detailed Description

The present invention will be further described with reference to the following embodiments.

Example 1

A wheelchair lifting control device comprises a control system; the control system comprises a programmable controller and a programmable controller expansion I/O port module; as shown in fig. 1, the input end of the programmable controller is respectively connected with the remote controller, the travel switch and the limit switch; the remote controller circuit is shown in fig. 2, and the remote controller remotely controls the input signal of the programmable controller to ensure the accuracy of the input signal. The travel switch and the limit switch provide in-place signals to be input into the programmable controller when the wheelchair lifting control device is lifted in place. The output end of the programmable controller is connected with the motor driver, the electromagnetic lock and the alarm device; after the programmable controller inputs signals at the input end, corresponding output signals are output to each component according to the preset program and the difference of the input signals, and then each component makes corresponding actions according to the obtained signals. In the embodiment, the electric cylinder is controlled by controlling the motor driver to complete the lifting action of the wheelchair; the programmable controller can also control the work of devices such as an electromagnetic lock, an indicator light, a buzzer and the like. The relay is connected with the programmable controller, the control point range is expanded, the control quantity is increased, and meanwhile, the signal output by the programmable controller is amplified.

When the electromagnetic lock receives a signal of the output end of the programmable controller, the electromagnetic lock is automatically unlocked, and all parts of the wheelchair lifting device can start to act.

The programmable controller and the motor driver are respectively connected with the power module and are powered by the power module.

The power module is provided with a selection switch, and power supplies with different voltages are selected to serve as emergency power supplies of the wheelchair lifting device when the power module is powered off. The motor driver is connected with the electric cylinder, and after the motor driver obtains a signal output by the output end of the programmable controller, the electric cylinder is driven to complete the lifting of the wheelchair.

When the lifting process is interfered by external force or the power is cut off, the output end of the programmable controller outputs a signal to the alarm device, the alarm device is internally provided with a buzzer and an indicator lamp, the buzzer sends out alarm sound, and the indicator lamp sends out in-place signal light. The wheelchair lifting control device is also provided with an ascending button and a descending button, when a user presses the operating button, the wheelchair is controlled to ascend and descend, and when the wheelchair ascends and descends in place, the travel switch and the limit switch can send in-place signals.

The specific use flow of the wheelchair lifting control device is as follows:

1. firstly, rotating a selection switch, and selecting a main power supply or a standby power supply as a power supply of the wheelchair lifting control device;

2. and (4) pressing an unlocking button S1 on the remote controller, electrifying for unlocking, unlocking the electromagnetic lock, and manually pushing out the hoister in the wheelchair lifting control device after unlocking is finished until the limit switch is touched. And after the limit switch is triggered, the push rod is unlocked and locked. After a signal sent by the button S1 and a locking limit signal of the unlocking push rod are triggered, the magnetic attraction lock is unlocked, and then the magnetic attraction lock is manually pushed out of the ramp for 90 degrees and is laid flat.
