Light-transmitting key with elastic support arm

Technical Field

The present invention provides a transparent button with an elastic support arm, and more particularly to a transparent button with an elastic support arm, which has better transparency and is more stable in use.

Background

The keyboard is a typewriter type device, which is composed of keys of different keyboard technologies and an electronic switch system. The primary function is to input data, which may be used in a computer system to operate other machines or devices. In the 1970 s, typewriters and keyboards replaced punch cards and punch tapes, which became the main input and operation modes of computers, and mice were added after the 1980 s. In general use, a keyboard is used for inputting characters, and characters, numerals, and symbols can be input in application software such as a word processor, a web browser, or a social media.

The keyboard is used by pressing each key to trigger the corresponding effect to generate a signal, thereby achieving the function of inputting data. With the progress of the times, the technical improvement of the key is more and more diversified. In general, a resilient spring or elastic structure is disposed at the center of the lower side of the key, so that the resilient effect is more stable, but if the resilient spring or elastic structure is used, various types of light and shadow effects cannot be generated by using the transparent key. Therefore, if the user wants to view the screen at the lower side, the spring and the elastic structure are placed at the side edge, but the spring effect is not uniform or the spring is not complete when the key is pressed.

Therefore, how to solve the above conventional problems and drawbacks is the direction in which the applicant of the present invention and the related manufacturers engaged in the industry desire to research and improve.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned shortcomings, the applicant of the present invention has searched relevant information, evaluated and considered in many ways, and designed the transparent button with elastic support arm that is more stable and has better transparent effect when pressed through continuous trial and modification based on the years of experience accumulated in the industry.

The utility model discloses a main aim at: the elastic support arm is matched with the elastic contact piece to achieve more stable pressing action and light transmission effect.

To achieve the above object, the main structure of the present invention comprises: the display device comprises a supporting plate, a thin film circuit arranged on the supporting plate, at least one through hole formed in the supporting plate, at least one display piece arranged at the lower side of the supporting plate, at least one light-transmitting key arranged on the supporting plate, at least one elastic supporting arm connected to the edge of the light-transmitting key, at least one jacking convex block arranged at the side of the light-transmitting key, and at least one elastic abutting piece arranged at the lower side of the jacking convex block, wherein the elastic supporting arm comprises a bending connecting section connected with the light-transmitting key, a vertical elastic section connected with the bending connecting section, and a plate end connecting section connected with the vertical elastic section.

Furthermore, a covering part is arranged on the supporting plate.

Furthermore, the covering part is provided with at least one auxiliary positioning hole for the transparent key to partially pass through.

Furthermore, the elastic support arm is formed by extending the light-transmitting key.

Furthermore, a rebound auxiliary support is arranged between the light-transmitting key and the support plate.

Furthermore, the resilient auxiliary support has a plurality of supporting members pivotally connected to the transparent button, and a plurality of pivot shafts respectively disposed on the supporting members.

Furthermore, the supporting plate is provided with a plurality of pivoting parts for pivoting the pivoting shaft.

Furthermore, an extension yielding section is arranged between the bending connecting section and the vertical elastic section.

By means of the structure, the display part and the transparent key are arranged at the through hole of the supporting plate, and meanwhile, the jacking convex block and the elastic support arm are arranged on the side edge of the transparent key, so that the viewing angle of a user can not be blocked completely, and a better transparent ornamental effect can be achieved.

When a user presses the transparent key, the pressing projection is pushed to press the elastic contact element and the elastic support arm is pushed to generate a deformation action, so that the elastic contact element is used for pressing the thin film circuit to generate a corresponding signal. And because the elastic support arm can change the angle of extension through the connection segment of buckling, and install in the backup pad through board end connection segment, so when the elastic support arm warp, then can make perpendicular elastic segment produce deformation, borrow this to accumulate the power way of resilience, give the stable resilience force of printing opacity button with cooperation elastic conflict piece, and owing to have the stable effect of elastic support arm and elastic conflict piece simultaneously, so can let the printing opacity button reach the straight up and down moving effect when pressing, prevent to produce the situation of skew, borrow this stability when strengthening whole pressing.

By means of the technology, the problem that the conventional transparent key is unstable when pressed can be broken through, and the practical progress of the advantages is achieved.

With the above description, the structure of the present technology can be understood, and the advantages of more stable pressing and better transmittance can be achieved according to the corresponding coordination of the structure, and the detailed description will be described below.

Referring to fig. 1 to 4, it is shown that the perspective view to the resilience diagram of the first preferred embodiment of the present invention, when the above-mentioned components are combined, it can be seen clearly from the figure that the user can place the supporting plate 1 at the upper side of the display element 3, align the display element 3 at the position of the through hole 11, and then place the transparent key 4 at the upper side of the through hole 11, so that the pressing protrusion 42 presses against the elastic pressing element 5 and the plate end connecting section 413 of the elastic supporting arm 41 is connected to the supporting plate 1, and the elastic supporting arm 41 can change the extending direction through the bending connecting section 411, thereby further reducing the overall space.

Thus, since the elastic support arms 41 and the elastic contact elements 5 are disposed at the side of the transparent keys 4, the viewing angle of the central display 3 is not obstructed, and the transparency and the viewing quality are improved. When a user presses the transparent key 4, the pressing bump 42 is pushed to press the elastic contact element 5, and at the same time, the vertical elastic section 412 is driven to bend and deform to accumulate elastic force, when the elastic contact element 5 is pressed, the thin film circuit 2 is pressed to generate a corresponding signal, and then the transparent key 4 returns to the original position through the resilience force given by the elastic contact element 5 and the vertical elastic section 412, so that the transparent key 4 can achieve a stable displacement mode similar to straight-up and straight-down, and the movement effect can be more stable when pressed.
