Abstract
The invention relates to a key structure. The key structure comprises a key part and a key cap part arranged on the key part, the key part is arranged on a circuit board, a cover plate covers the key structure, the key cap part and the key part are molded by injection, and the key part is fittingly matched with the cover plate. Compared with the prior art, the key structure has the advantages of simple structure, water proofness and dust proofness.
Description
Technical field
The present invention relates to a kind of electronic device, especially relate to a kind of press-key structure.
Background technology
Hand-held product button common in the market, after being used for a while, the font of keytop there will be wearing and tearing obscission, affect product to continue to use, tracing it to its cause, this is determined by the manufacture craft of button itself, this button adopts typography, directly by character printing at keytop, when user at operation push-button time, hand meeting direct friction is to font ink, time is long there will be above-mentioned problem naturally, the hand perspiration of people has certain corrosivity simultaneously, this exacerbates the falling speed of font, this problem is at mobile phone, especially outstanding on remote controller!
For the demand of this kind of button, also has a kind of conventional way, P+R button is called in industry, its specific practice is, button is divided into surface hard transparent plastic (being generally PC material) and the inside elastomeric material (being generally Rubber silica gel) two parts, at transparent plastic medial surface print character, then by plastics together with rubber adhesion, wait hand so in use and just do not reach button character, would not occur that character is by the problem come off that rubs, but this frame mode complex process, cost of manufacture is high, its technique relates to plastic cement injection moulding, rubber is hot-forming, printing, paste assembling and its supporting operation, its production efficiency, yield is all relatively low.
Above-mentioned two kinds of modes, if product has the requirement of water proof and dust proof aspect again, for the how again risk necessarily of button design person and challenge!
Summary of the invention
Object of the present invention is exactly provide to overcome defect that above-mentioned prior art exists that a kind of structure is simple, the press-key structure of water proof and dust proof.
Object of the present invention can be achieved through the following technical solutions:
A kind of press-key structure, described press-key structure comprises the keycap part that key body divides and be located at key body to divide, described key body sets up separately on circuit boards, and this press-key structure is covered with cover plate, described keycap part and key body divide injection mo(u)lding, and described key body divides to mate with cover plate and is connected.
Described key body divides to be made up of TPU material.
Described keycap part is made up of PC rigid plastics.
Described key body divides the buckle being provided with and being connected with cover plate.
Described buckle is provided with multiple.
Compared with prior art, the present invention adopts TPU material and PC rigid plastics double-shot moulding, does not print by the problem come off that rubs, and does not also have the production technology that P+R button is complicated like that; Key body divides employing TPU elastomer, ensures the resilience requirement of button on the one hand, effectively can solve the demand of key hole place water proof and dust proof on the other hand.
Accompanying drawing explanation
Fig. 1 is the structural representation of keycap part of the present invention;
Fig. 2 is the structural representation that key body of the present invention divides;
Fig. 3 is the structural representation after keycap of the present invention and key body combine;
Fig. 4 is the structural representation after the present invention assembles finished product;
Fig. 5 is the side sectional view of Fig. 4.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As shown in Figure 1-Figure 3, a kind of press-key structure, comprise key body and divide 2 and be located at key body and divide keycap part 1 on 2, described keycap part 1 and key body divide 2 injection mo(u)ldings, the color that keycap part 1 and key body divide 2 employings different, plastic double-color moulding process can use the plastics of two kinds of unlike materials and different colours on a plasthetics, and a step injection moulding completes, do not print by the problem come off that rubs, there is no the production technology that P+R button is complicated like that yet.Described key body divides 2 to be made up of TPU material, ensures the resilience requirement of button on the one hand, effectively can solve the demand of key hole place water proof and dust proof on the other hand.Described keycap part 1 is made up of PC rigid plastics.
As shown in fig. 4-5, after above-mentioned press-key structure is installed, key body divides 2 to establish on the circuit board 4, cover plate be located in keycap part 1, key body divides 2 to be provided with the buckle be connected with cover plate, key body divide 2 under the effect be stressed buckle compressed, sealing function can well be played, buckle is provided with multiple, distribution is arranged on the whole circle of button, coordinate the design of cover plate whole circle muscle position, under certain rigid pressure (usually adopting screwed lock to make a concerted effort to realize), make TPU decrement about 25 ~ 30%, effectively can intercept water and dust enters into machine intimate by key hole.
The above is indivedual case study on implementation of the present invention, the interest field that non-invention is advocated; be not limited thereto, be allly familiar with this skill personage, according to the technology contents that the present invention is disclosed; can think easily and slightly change, the protection range not departing from the present invention all should be belonged to.
Claims (5)
