Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of cabinet, concretely is a kind of anti-pinch hand hanging basket and storage cabinet. BACKGROUND
[0002] The existing cabinet hanging basket anti-pinch hand device mainly relies on the current fluctuation of detection motor to realize its anti-pinch hand function.This technical principle is based on the basic principle that the current consumption of motor changes when encountering external resistance in the running process.Specifically, the working current of motor is relatively stable when driving the hanging basket to lift.However, when the hanging basket encounters obstacles (such as human hand) in the lifting process, the motor will increase current consumption because it needs to overcome additional resistance.This current fluctuation is detected by the sensor in the anti-pinch hand device and used as a trigger signal to make the motor stop running, thereby preventing the occurrence of pinch accidents.However, this anti-pinch hand device based on current fluctuation has obvious limitations.Firstly, the current fluctuation of motor needs to reach a certain threshold to be accurately detected by the sensor.This means that only when the blocking force is large enough to cause the current fluctuation to exceed the preset threshold, the anti-pinch hand device will trigger the stop.In actual use, this often means that the person will still feel pain after being pinched because the blocking force must be large enough to trigger the protection mechanism.Secondly, the current fluctuation of motor can be affected by various factors such as power voltage fluctuation, load change of motor itself, etc.These factors can cause false triggering or missed triggering, affecting the reliability and accuracy of the anti-pinch hand device.In addition, the sensitivity of the anti-pinch hand device based on current fluctuation may differ for different types of obstacles (such as fingers, objects, etc.).In some cases, the device may not be able to detect small obstacles in time, thereby failing to effectively prevent pinch accidents.
[0003] In summary, although the existing cabinet hanging basket anti-pinch hand device can achieve anti-pinch hand function to some extent, its detection principle based on motor current fluctuation has obvious limitations.In order to improve the safety and reliability of the anti-pinch hand device, more advanced and sensitive detection technologies need to be explored, such as using sensors to directly detect obstacles to achieve faster and more accurate response to pinch accidents.
