Multiple direction operational and controlled key

Abstract

A multi-directional control button is installed on a small electronic device with an upper cover, which can absorb assembly and manufacturing tolerances. It includes a micro-rod switch and a movable guide button, and the movable guide button is used for fine-tuning the multi-directional control. The upper and lower relative positions of the button and the upper cover of the small electronic device enable the multi-directional control button to fit tightly into an opening of the upper cover, wherein the movable guide button adopts a two-piece design in which the body is matched with a bushing, and the bushing The upper end is movably connected with the main body, and the other end below the shaft sleeve is tightly sleeved on the micro-rod switch, and the elastic member disposed between the main body and the shaft sleeve is pressed upward against the main body. In addition, the multi-direction control button also includes an elastic support for supporting the movable guide button so that the movable guide button maintains a horizontal position.

Description

technical field [0001] The invention relates to a button design, in particular to a multi-directional control button used on a small electronic device. Background technique [0002] With the rapid development of the high-tech industry and the ever-changing technology, many electronic products are introduced from the old to the new. In recent years, the functions of portable products have become more and more diversified, allowing users to flexibly use them to handle personal daily work or personal affairs regardless of occasions and time constraints, and also allow people to access information with their fingers and take the information with them. . For example, personal digital assistants (Personal Digital Assistance, PDA), regardless of commercial or personal use, are increasingly popular among consumers for their unique portability and simple user interface. In order to make portable products more humanized and more convenient to carry, their app...

Problems solved by technology

Generally, to solve the phenomenon of unequal size of the gap, it will take advantage of the visual blind spot to increase the gap between the guide button 210 and the upper cover 220, for example, keep a gap of 1mm between the button and the upper cover, so that the generated Compared with more than a dozen tolerances, it is not obvious. However, this method of increasing the gap highlights the gaps between the product components that are not sealed, and the appearance of the product is not delicate enough.

[0007] In addition, when the user indirectly operates and controls the micro-lever switch 230 below it by pressing the guide button 210, the design of the guide button 210 will directly affect the user's sense of touch and whether it is easy to operate, such as figure 2 As shown, the traditional guide button 210 adopts a one-piece design, which is only an extension structure sleeved on the micro-lever switch 230. When manufacturing tolerances occur, it often causes tilting or keying. When pressing, it is stiff due to the direct transmission of the force of the micro-rod switch and lack of flexibility.
