Bed provided with protective device

Abstract

The invention discloses a bed equipped with a protective device, comprising: a gear box, in which a driving gear is rotatably installed, and two parallel racks are meshed on the driving gear, and each rack is meshed with two driven gears on both sides of the rack. The gear is fixed; the vibration sensor module is used to detect the vibration frequency of the bed; the microcontroller is used to receive the signal of the vibration sensor module, and generates a corresponding switch signal control command after analysis and processing; the relay module is used to receive the micro-control The switching signal of the device is analyzed and processed to control the relay to open or close; the reduction motor has a driving gear fixed on its main shaft, and one of the power input terminals of the reduction motor is located between the armature of the relay and the electromagnet. The invention detects the vibration of the bed through the vibration sensor module, triggers protective measures, realizes intelligent control of the protective device of the bed, and effectively protects people resting on the bed.

Description

technical field [0001] The invention relates to the field of security technology, in particular to a bed equipped with a protective device. Background technique [0002] An earthquake is a natural phenomenon in which vibrations are caused by the rapid release of energy from the earth's crust, during which seismic waves are generated. Earth's plates are squeezed and collided with each other, causing dislocation and rupture at the edge of the plates and inside the plates, which is the main cause of earthquakes. Earthquake is a severe and unpredictable natural disaster, so it is particularly important to prevent earthquake disasters. Beds are furniture for people to sleep on and are usually placed in bedrooms. After thousands of years of evolution, it is not only a tool for sleeping, but also one of the decorations of the family. Ordinary beds cannot protect the people who sleep on the bed in natural disasters such as earthquakes and other larger vibrations, so many various ...

Problems solved by technology

[0004] However, the existing anti-vibration beds have the following disadvantages: 1. The trigger mechanism of the mechanical structure is not sensitive, and only when the bed is under strong vibration, the protective measures will be triggered; 2. The trigger mechanism of the mechanical structure is too complicated, easy to age, and poor in performance. Stable, high repair rate, the trigger mechanism is prone to failure, unable to effectively protect people resting on the bed, causing a large number of casualties; 3. The trigger mechanism of the complex mechanical structure is large in size, too heavy, takes up a lot of space, and cannot be moved. Convenience: 4. The shape of the anti-shock bed with mechanical structure trigger mechanism is not beautiful enough
