Abstract

The utility model discloses a keycap structure, which contains a keycap structure, a connection structure and a reinforcing component; wherein the reinforcing component is positioned at the bottom of the keycap through the connection structure; as the keycap and the reinforcing component are separately molded, thus not only simplifying the manufacturing method and avoiding the deficiency that the surface of the keycap shrinks when be molded cause the traditional arrangement of the reinforcing component; moreover, as the keycap structure or realistic needs to manufacture the different trends, thickness, heights or the materials of the reinforcing component, so as to achieve the aim of reinforcing the keycap.

Description

The keycap structure

Technical field

The utility model relates to a kind of keycap structure, particularly relate to the keycap structure that a kind of keycap and reinforcing element separate moulding, can simplify manufacture method, and can be according to the reinforcing element of keycap structure or the different trends of actual required making, thickness, height or material, really reach the purpose of strengthening keycap, be applicable to computer, mobile phone, or the button manufacturer of PDA(Personal Digital Assistant) and association area thereof.

Background technology

Computer, mobile phone, or the button of PDA(Personal Digital Assistant) and correlated product thereof, have the difference of length size or external form according to the function difference, and in appropriate location, keycap bottom ribs or balancing pole are set according to the structure difference, can on average force on the whole button when guaranteeing to push, the phenomenon that unlikely generation is crooked or the application of force is uneven, wherein, because the space key length is the longest, the setting of its ribs or balancing pole is more indispensable; The way of dealer's custom is that with regard to the mode of one-body molded ribs, it has following main disappearance in the one-body molded ribs structure in keycap bottom at present:

Based on the frivolous miniaturization demand of product, the thinning that also becomes of keycap thickness, and ribs often causes key cap surface to shrink, influence outward appearance if design is improper or thickness is too big, makes the rising of moulding disqualification rate;

The layout of ribs is subject to the keycap polycrystalline substance, can't reach the purpose of uniform balance pressing force.

See also Fig. 1, it is No. the 6726093rd, U.S.'s patent of invention " Keyboard and key structurewith scissors-shaped frame ", this case is on a keycap 1a bottom and a base 4a guide runner 11a, 43a to be set respectively, and the first end 31a, the second end 32a with balancing pole 3a is arranged in this guide runner 11a, 43a respectively again; Though the problem that this case structure can avoid tradition may cause key cap surface to shrink in the one-body molded ribs in keycap bottom, still there is following disappearance:

At scissor construction 2a design, be not suitable for other form button;

This balancing pole 3a and scissor construction 2a are interlaced, cause the difficulty in the assembling;

The area of keycap 1a and base 4a must be strengthened, keycap 1a bottom level is increased,, cause volume and weight to increase to hold this guide runner 11a, 43a.

Complex structure, cost height.

See also TaiWan, China patent application case shown in Figure 2 number No. 93216053 " keyboard structure " again, it is to extend a junction 14 in keycap 1 bottom, terminal one-body molded balancing pole 16 at this connecting portion 14, these balancing pole 16 two ends are arranged in a pair of trip 26 separately rotationally, this case emphasizes that it not only can reach the purpose of balance button by said structure, can reduce cost simultaneously, yet with this case structure and first graph structure mutually more as can be known, the connecting portion 14 of this case and the set-up mode of this balancing pole 16, the first end 31a for the balancing pole 3a of this U.S.'s case of Fig. 1, the conversion of the second end 32a framework, this trip 26 is equivalent to the guide runner 43a of Fig. 1, this connecting portion 14 is equivalent to the second end 32a of Fig. 1, it is one-body molded with this keycap 1 being in this connecting portion 14 than big-difference, yet, because one-body molded event, not only make the structure complicated of keycap 1, can't solve simultaneously the problem that traditional one-body molded ribs causes key cap surface to shrink easily again, moreover, in limited space, keycap 1 bottom, complicated connecting portion 14 must be set, balancing pole 16 and trip 26 or the like member, its intensity that can reach is made us doubt.

The utility model content

Because the disappearance of prior art, main purpose of the present utility model is to propose a kind of keycap structure, its reinforcing element is arranged at the bottom surface of keycap by syndeton, because this keycap is to separate moulding with this reinforcing element, not only can simplify manufacture method, avoid tradition because of the shortcoming that reinforcing element causes the key cap surface moulding to shrink is set, and can reach the purpose of reinforcement keycap really according to the reinforcing element of keycap structure or the different trends of actual required making, thickness, height or material.

For achieving the above object, the utility model proposes a kind of keycap structure, it comprises:

One keycap, tool one bottom surface;

One connecting structure; And

One reinforcing element is arranged at the bottom surface of this keycap by this syndeton.

Preferably, this reinforcing element is flat plate body.

Preferably, this reinforcing element is provided with at least one shaft of rib.

Preferably, this shaft of rib is formed in one or separately takes shape on this reinforcing element.

Preferably, the trend of this shaft of rib is for being parallel to each other or mutually vertical, or interlaced one of them or its combination, or can be bending and be the strip shape body of arbitrary shape.

Preferably, this connecting structure is can chimeric mutually hole and male member.

Preferably, this hole is arranged on this reinforcing element, and this male member is arranged at this keycap bottom and corresponds to this hole place.

Preferably, this male member becomes tight fit with this hole.

Preferably, this male member is arranged in and melts with heat behind this hole or viscose is fixed again.

Preferably, this connecting structure is grab and groove.

Preferably, this grab is arranged at this keycap bottom, and this groove is arranged at this reinforcing element and corresponds to this grab place.

Preferably, this connecting structure is anchor clamps, by its chucking power in order to this connector of clamping.

Preferably, the material of this reinforcing element and this connecting structure is one of them or its combination such as metal, plastics, composite material.

Preferably, this connecting structure can separate moulding or one-body molded with this keycap.

Advantage of the present utility model is, its reinforcing element is arranged at the bottom surface of keycap by syndeton, because keycap is to separate moulding with reinforcing element, not only can simplify manufacture method, avoid tradition because of the shortcoming that reinforcing element causes the key cap surface moulding to shrink is set, and can reach the technique effect of strengthening keycap really according to the reinforcing element of keycap structure or the different trends of actual required making, thickness, height or material.
