Electromagnetic power driving mechanism and care device with the driving mechanism

Abstract

The invention discloses an electromagnetic power driving mechanism and a care device with the driving mechanism. The electromagnetic driving mechanism comprises magnetic components, two groups of independent elastic components, and a movable part; the magnetic components are arranged at two sides of the movable part and one end of the movable part; each magnetic component comprises a coil, an ironblock and a magnet; the coil is sleeved on the iron block, the magnet is arranged on the elastic component, the magnet and the iron block sleeved with the coil are arranged at intervals; the coil ispowered on so that the iron block sleeved with the coil produces the magnetism, thereby driving the magnet to move; the magnet drives the connected elastic component to move, thereby driving the movable part connected with the elastic component to move. Through the adsorption relation between the iron block and the magnet, the magnet movement is controlled, the magnet drives two groups of independent elastic components to differentially move, thereby controlling the movable part connected with the elastic component to move; the balanced differential driving can obviously reduce the noise produced by the movable part in vibration and the vibratory sensation on the shell, the customer experience is better, and the service life is longer.

Description

【Technical field】 [0001] The invention relates to the technical field of motor drive, in particular to an electromagnetic power drive mechanism and a nursing device with the drive mechanism. 【Background technique】 [0002] With the improvement of people's living standards, people's demand for electric products is increasing, especially in personal care products, such as cleaning brush products, which use automatic control methods to realize automatic movement of the brush head, such as rotation, Reciprocating up and down motion, left and right motion, etc. [0003] The automatic driving mode in the prior art is to use a motor to realize the reciprocating rotary drive of the movable part through a converter. It generally faces problems such as large size and heavy weight, high cost, high noise, insufficient life, and high manufacturing precision requirements. [0004] For this reason, many existing products propose the method of direct drive of electromagnetic force, especi...

Problems solved by technology

However, in many designs, it is often necessary to set multiple sets of expensive special-shaped magnets. In order to ensure accuracy and life strength, a large number of metal components are used, and the final manufacturing cost is too high, which is not conducive to market promotion.

Most of the existing products and due to the congenital deficiencies in the design, there is almost an insurmountable problem that the user feels too much vibration when using it, which causes discomfort.
