Axial actuating device with elastic coupling part

Abstract

The invention relates to an axial actuating device with a flexible link part capable of carrying objects and making the objects actuate, including: a fixed part which is a permanenet magnet, a movement part which is a loop winding and movably arranged in the fixed part; and a link part the integer of which coating out of the fixed part and including: a support part which is a hollow frame and arranged out of the fixed part and sleeved with the fixed part; an actuating part which is a tabulate workpiece and arranged at one side opening of the frame and connected to the movement part; a plurality of connection parts together with the actuating part arranged between the support part and the actuating part at the side opening of the frame, and stretchably connecting the support part and the actuating part. The axial actuating device ensures that the carried objects move in the axial direction without deflection, uses the link part to link the fixed part and the movement part, wherein the link part has an effect for limiting a displacement amount of the movement part and can protect the axial actuating device, also has the effect of shock-absorption and anti-throwing and can protect the whole device from damaging and influence the function.

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
