Description

Knob Structure of Electronics

The present invention relates to a knob structure of an electronic product, and more particularly, to a knob structure improvement of an electronic product provided on a front panel to perform various controls.

In general, most electronic products are provided with a plurality of knobs and operated by their manipulations, and an example thereof is illustrated in FIG. 1. As shown in the drawing, a knob assembly 30 having a plurality of pressing protrusions 34 each having a unique function is provided on its front surface. And it is provided with a front panel 10 having a plurality of through holes 12 to which each pressing projection 34 is coupled. The knob assembly 30 is mainly provided inside the main chassis (not shown) to press the switch 22 installed on the main PC 20 for processing an electrical signal, the front panel 10 It is configured to allow the user to selectively press the projections 34 protruding through the through holes 12 formed on the user.

According to FIG. 2, the knob assembly 30 has a base 31 and a plurality of elastic pieces 32 extending upwardly from the base 31 and retaining a predetermined elasticity with respect to the base 31. Protruding in the vertical direction from the upper end of the elastic piece 32 is provided with a pressing projection 34 protruding into the through-hole 12 of the front panel 10, the elastic piece 32 by pressing the pressing projection 34 It is comprised so that a certain angle rotation may be performed backward. In addition, the lower end of each of the elastic piece 32 is projected in the opposite direction to the pressing projection 34, the working piece 36 is arranged so that the end thereof corresponds to the upper surface of the switches 22 on the main PC ratio 20 It is constructed integrally.

On both sides of the base 31, a fixing piece 38 having a fixing hole 38a extending upward and press-fitted to the high information (not shown) of the front panel 10 is integrally formed.

In the conventional knob structure having such a configuration, when the pressing protrusion 34 is pressed, the elastic piece 32 is elastically rotated backwards by a predetermined angle relative to the base 31. Therefore, the operation piece 36 which is integrally formed with the elastic piece 32 rotates downward and pressurizes the switch 22. When the force is removed, the pressing projection 34 is caused by the elastic restoring force of the elastic piece 32. It will return to its original position.

However, the knob as described above has a problem in that the pressing projections 34 are formed at the same height, so that the space utilization efficiency of the front panel 10 is lowered.

That is, in the conventional knob structure as described above, since the switches 22 on the main PC ratio 20 are arranged side by side, in the design of the knob, they are designed side by side along the arrangement of the switches, as shown in FIG. Likewise, the through holes 12 are formed on the front panel 10 side by side. Therefore, a dance space is generated in the upper part of the through space, which is disadvantageous in terms of design, and has a problem that the size of the front panel 10 is enlarged, resulting in the compactness of the electronic product.

In order to compensate for this, a method of changing the arrangement of a plurality of knobs integrally is being developed. For example, another PC is installed vertically on the main PC 20 to install a switch there. And the way to configure the knob to fit the switch has been developed, which can vary the design, but the switch 22 on the main PC ratio 20 is arranged in a horizontal state as illustrated in Figures 1 and 2 It is still not applicable to the type installed.

Accordingly, the present invention was conceived in view of the above-described conventional problems, and its purpose is to provide a variety of shapes while integrating a plurality of knobs, thereby improving the space utilization efficiency of the front panel. In providing a knob structure.

3 shows an exploded view of the knob structure according to the present invention. According to the present invention, the front panel 100 includes a plurality of through holes 110. A knob assembly 300 having a plurality of pressing protrusions inserted through the through holes 110 is provided. The knob assembly 300 is mainly provided inside the main chassis (not shown) to operate the switch 210 installed on the main PC 200 to process the electrical signal, on the front panel 100 Protrudes through the through-holes 110 formed in the user is configured to selectively press to operate.

The knob assembly 300 includes a base 302 and a plurality of first elastic pieces 310 extending upward from the base 302 and having a predetermined elasticity with respect to the base 302. First pressing protrusions 312 protruding forward from the upper ends of the first elastic pieces 310 and protruding into the through holes 110 of the front panel 100 are provided to press the first pressing protrusions 312. The first elastic piece 310 is configured to achieve a predetermined angle of rotation backward. In addition, the first operation is projected in the opposite direction to the first pressing projection 312 at the lower end of each of the first elastic piece 310, the end of the first operation is arranged so as to correspond to the upper surface of the switches 210 on the main PC 200 (200) Pieces 314 are integrally constructed.

On both sides of the base 302, a pair of fixing pieces 330 having a fixing hole 332 which is extended upward and press-fitted into the high information 130 of the front panel 100 is integrally formed.

Meanwhile, at least one second elastic piece 320 having a height higher than that of the first elastic piece 310 protrudes upward from the outer side of the first elastic piece 310. The second elastic piece 320 may be configured by extending any one selected first elastic piece. The second elastic piece 320 is integrally formed with a second pressing protrusion 322 protruding through the through hole 120 of the front panel 100 at an upper end thereof. In addition, a second end of the second elastic piece 320 protrudes in a direction opposite to the second pressing protrusion 322, that is, rearward, and an end thereof is arranged to correspond to the selected switch 210 on the main PC 200. The operating piece 324 is configured integrally.

According to the present invention, the second elastic projection 322 is formed at an arbitrary position of the extension piece 326 by forming an extension piece 326 crossing the upper portion of the first elastic pieces at the upper end of the second elastic piece 320. It is preferable to form. An end of the extension piece 326 is connected to any one of the pair of fixing pieces 330 by a connection piece 328. The connecting piece 328 is configured to be thinner than the extension piece 326 to facilitate deformation, and in the process of connecting the fixing piece 330 and the extension piece 326, at least two bends 328a are provided to the second pressing protrusion. It is configured to allow the second elastic piece 320 to elastically rotate rearward when pressing 322.

According to the present invention having such a configuration, as shown in FIG. 4, when the first pressing protrusion 312 is pressed, the first elastic piece 310 rotates backward, so that the first operating piece 314 corresponds to a switch ( 210 will be activated.

On the other hand, when the second pressing protrusion 322 is pressed, the second elastic piece 320 is rotated to the rear so that the second operating piece 324 operates the switch 210 corresponding thereto. In this case, the second elastic piece 320 is elastically deformed at the lower end thereof and rotates rearward, and the connecting piece 328 is extended to allow the second elastic piece 320 to rotate.

When the external pressure, that is, the pressing force of the pressing protrusions is removed, the first elastic piece 310 and the second elastic piece 320 are returned to their original positions. At this time, the connecting piece 328 also helps the second elastic piece 320 to return to its original position by the elastic restoring force.

According to the present invention, since the upper shape of the second elastic piece 320 may be arbitrarily changed, the second pressing protrusion 322 arranged at a position different from the first pressing protrusion 312 may be configured to implement diversification of the design. Done.

As described above, the knob structure of the electronic product according to the present invention comprises a plurality of first elastic pieces each having a pressing protrusion and an operating piece, and at least one second elastic piece having at least higher than the first elastic pieces. At the same time, the upper end of the second elastic piece is elastically fixed to the fixing piece by the connecting piece so that the position of the pressing protrusions does not have to be arranged in a line, so the layout design of the pressing protrusions is easy. In addition to being able to be applied to the form in which the PCB is arranged in a horizontal state, it has the effect that can contribute to the compactness of the product by reducing the dancing space.
