How to make a child bed auto-swing mechanism

The device for swinging a children's bed can be made independently; it has a pendulum mechanism. The pendulum mechanism may be longitudinal or transverse. Longitudinal is designed to swing the bed along its long side, while the transverse helps to swing the bed along the short side. Such a device is best suited for standard sizes of a bed made of wood, such as birch or beech.

The device is characterized by the simplest mechanism of action. It works on the principle of the famous “desktop perpetual motion machine”. A coil is located in a special stand, and a magnet must be placed in its swinging part. The magnet should preferably be neodymium and have the shape of a washer; its diameter can be from 8 mm to 15 mm. After the “engine” is rocked to the side, it will swing from side to side until the batteries are sitting in it. A wired coil is recommended as a sensor. The magnetic system should be as compressed as possible, the magnet should produce its movements with minimal gaps. This allows you to achieve the highest efficiency of the device.

In order for this device to be able to move the bed, it is necessary to provide for the displacement of the coil relative to the magnet, being in equilibrium. For convenience, it is recommended to create the ability to remote control. For this, a normal Chinese pulse is suitable, the cost of which is very low. The remote must have 4 buttons. For each button, you need to set your own command - start, stop, more and less.

Such a device has several advantages:

1. Silent - there are no motors and gears in it. If desired, you can additionally create sound insulation, but even without it, the device does not make noise.
2. Easy installation on the bed. Any person who has absolutely no knowledge in this area can cope with this task.
3. Universal - the construction is suitable for use on almost any type of bed.
4. Perhaps remote control - this allows you to swing the crib from a calm state.

This device is able to adapt to the frequency of natural oscillations of the bed, and is also able to push it at certain points that a person will ask using a remote control.
