Description

Slide module {Slide module}

The present invention relates to a sliding module for guiding two objects to slide and engage with each other.

In general, in the manner in which the two objects are coupled to each other, as shown in Figure 1 to form a rail portion (1a, 2a) to be joined to the first member 1 and the second member 2 to be bonded to There is a way that the rails (1a, 2a) are slid together and fitted to each other.

By the way, such a conventional sliding coupling structure forms and joins the rail portions 1a and 2a, which protrude high from the first member 1 and the second member 2, so that the space is restricted. It was difficult to apply such a coupling guide structure.

This problem has recently emerged as a problem to be solved in view of the trend toward miniaturization and slimming of various devices. Therefore, there is a need for a new guide structure capable of smoothly sliding two objects even in a narrow space.

In addition, since the structure and shape of the rail portion must be formed differently according to the shape of the member to which the sliding coupling is required, there is a disadvantage in that different rail portions must be manufactured for each member.

In addition, there is a lot of inconvenience in use because the user has to check by visually how much distance the member for sliding operation has moved.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a slide module that can reduce a space required for rail mounting and can be commonly applied to members of different types.

In addition, another object of the present invention is to provide a slide module that is convenient for use by allowing the user to sense the sliding operation state of the slide module without using the visual.
