Axial actuating device with elastic coupling part

Abstract

This invention is an axial actuating device with flexible link part, and it can be used to carry objects and make the objects moving along the bearing, which including: the fixed part, the movement part, and the link part. The link part is used to combine the fixed part and the movement part to make the two parts forming mutual axial link state, and the fixed part and the movement part respectively fix the magnet and the coil, so when imposing the current to the movement part, the movement part can generate a relative displacement according to the current size and position, to achieve the purpose of providing the axial displacement, and meanwhile, since the mobile energy comes from the mutually exclusive force of the magnetic field, so it also has shockproof effect.

Description

technical field [0001] The invention is an axial actuating device with an elastic coupling part, especially an axial actuating device applied to a digital imaging device. Background technique [0002] Drive systems that can be carried around and used at any time generally have the characteristics of small size, light weight, and easy storage. Relatively, they may be dropped due to negligence, resulting in internal damage or malfunction. Therefore, the dependence on the protective device is bound to increase, but the increase of the protective device may also increase the number of components, resulting in increased volume, increased weight, and difficult storage, so that the original advantages no longer exist. Furthermore, from the point of view of light, thin, short, and small design concepts, the smaller size will inevitably increase the difficulty of assembly, resulting in an increase in cost. [0003] In portable electronic devices, motors are widely used. The growth r...

Problems solved by technology

[0004] Generally, there are several types of designs for connecting components, and these designs have their disadvantages: 1. Spring type, in which the spring presses the brush, because the axial length is too long, it is not suitable for miniaturization, and the mechanical spring Its rigidity coefficient is large, that is, it must overcome a large elastic force

2. The linear bearing type is just the opposite of the spring, it occupies a large space in the radial direction, and must have a positioning device, otherwise the displacement control cannot be performed

3. Leaf spring type, this design is the most commonly used coupling component on the market at present. It occupies a small space and is very suitable for miniaturization. It has a shockproof effect and is not suitable for products that are easy to fall
