Background

Currently, due to the rapid development of the technology industry such as computers, many electronic products require an input device such as a keyboard for operation. However, no matter indoors, outdoors or in a harsh environment, foreign substances such as water or dust may penetrate into the input device and be easily damaged. In addition, each key on the keyboard is provided with marks such as characters and diagrams, which are beneficial for an operator to identify and input correct instructions, but the exposed keys also easily cause the problems of difficult identification and the like caused by abrasion after the marks are used for a long time.

Therefore, the existing input device can cover each key through the waterproof film, the waterproof film is also matched with the position and the shape of each key to form a concave shape and a convex shape, and the waterproof and dustproof functions and the purpose and the effect of protecting the keycap mark and the like can be achieved through the covering and the arrangement of the waterproof film.

Please refer to fig. 1 and fig. 2, which are a schematic exploded perspective view of the waterproof keyboard and the base of the present invention and an exploded perspective view thereof, respectively. The invention provides a waterproof keyboard structure which can be conveniently assembled on a notebook computer, namely the waterproof keyboard structure is assembled on a base 1 of the notebook computer as shown in figure 1, has waterproof and dustproof effects and can maintain good hand feeling such as knocking, pressing and the like. As shown in fig. 2, the waterproof keyboard structure includes a keyboard module 2 and a keyboard frame 3; wherein:

the keyboard module 2 is mainly composed of a plurality of keys 20 arranged, each key 20 corresponds to a circuit board 21, the circuit board 21 can be a thin film circuit board, a conduction point (not shown) is formed below each key 20 through the thin film circuit, and the corresponding instruction can be transmitted through the circuit board 21 due to the fact that each key 20 contacts the conduction point when being pressed, so that the purpose of instruction input is achieved. In addition, as shown in fig. 3, by disposing the keys 20 on the circuit board 21, a key surface F1 formed by the keys 20 and an assembly surface F2 opposite to the key surface F1 can be defined for the keyboard module 2, wherein the assembly surface F2 is the back surface of the circuit board 21, and the back surface is not provided for the keys 20.

Referring to fig. 2 and 3, the keyboard frame 3 is used to surround the keyboard module 2, and may have a frame 30 stacked on the keyboard module 2 and a grating structure 31 integrally formed in the frame, where the grating structure 31 corresponds to the outside of the plurality of keys 20 of the keyboard module 2.

In view of the above, the present invention mainly forms an elastic waterproof layer 4 on the keyboard frame 3 by two-shot injection (double injection) or insert molding (insert molding), the elastic waterproof layer 4 is adhered to the frame 30 of the keyboard frame 3, and has a coating layer 40 covering the surface of the keyboard module 2 (i.e. the key surface F1) and a flange 41 extending from the periphery of the coating layer 40, the flange 41 has a sealing ring 410 protruding outward and continuously surrounding the keyboard frame 3, and the keyboard frame 3 and the elastic waterproof layer 4 are assembled on the keyboard module 2. More specifically, the coating layer 40 has ribs 400 corresponding to and adhered to the grid structure 31 of the keyboard frame 3, and a plurality of protective films 401 integrally formed between the ribs 400, each protective film 401 corresponds to and covers each key 20, and a distance d exists between each protective film 401 and the surface of each corresponding key 20; in other words, the inner surface of each overcoat film 401 is not bonded to the surface of each key 20.

As shown in fig. 1 and 4, the base 1 of the notebook computer is provided with a receiving space 10, and the keyboard module 2 is assembled into the receiving space 10 with the assembling surface F2 facing the base 1 and the keyboard frame 3. Accordingly, since the flange 41 of the elastic waterproof layer 4 is tightly attached to the base 1, the elastic sealing ring 410 is pressed and deformed by the inner wall 100 of the accommodating space 10, and a waterproof ring is formed between the two. In addition, the elastic waterproof layer 4 is made of liquid silicone, and a covalent bond is formed at the interface between the elastic waterproof layer 4 and the keyboard frame 3.

As shown in fig. 4, the keyboard frame 3 further has an insertion portion 32 extending downward from the periphery of the frame 30, the insertion portion 32 is sandwiched between the keyboard module 2 and the inner wall 100 of the accommodating space 10, a slot 101 recessed downward around the inner wall 100 is formed in the accommodating space 10, and the insertion portion 32 is further inserted into the slot 101. Through the above-mentioned equipment and cooperation structure, and further strengthen the steadiness that combines between keyboard module 2 and base 1 to improve the sealed effect to elastic waterproof layer 4. In other words, since the flange 41 is clamped between the embedded portion 32 and the inner wall 100 of the accommodating space 10, the clamping force applied to the elastic waterproof layer 4 is relatively large, so that the waterproof effect is relatively good, and the embedded portion 32 can also increase the contact area between the elastic waterproof layer 4 and the inner wall 100 of the accommodating space 10, so as to further improve the waterproof property. Furthermore, the sealing ring 410 on the flange 41 protrudes toward the inner wall 10 of the accommodating space 10, the flange 41 is pressed into the slot 101, and the sealing ring 410 is pressed by the inner wall of the slot 101 and the embedded portion 32, so that the waterproof performance can be further improved.

Therefore, the waterproof keyboard structure can be obtained through the structural composition.

Preferably, as shown in fig. 5, in the present invention, the protective films 401 of the elastic waterproof layer 4 are respectively covered on the keys 20, and the distance d exists between the protective films 401 and the surfaces of the keys 20, which means that the protective films 401 are not adhered to the surfaces of the keys 20. Therefore, when each key 20 is hit or touched, each protective film 401 has a sufficient amount of deformation without being deformed by the influence of the pressing stroke of the key 20; and each key 20 is not affected by the adhesion of the protective film 401 during the stroke of pressing. That is, the keys are deformed or pressed under the action of force without mutual interference, so that the pressing stroke of the keys 20 can be further maintained on the premise of achieving the waterproof and dustproof functions and protecting the surface marks of the keys 20, and the influence on the knocking hand feeling is avoided.

The embodiment also provides an assembling method of the waterproof keyboard structure, which comprises the following steps:

a) preparing a base 1 and a keyboard module 2, wherein the base 1 is provided with an accommodating space 10, and the keyboard module 2 comprises a key 20 surface and an assembly surface opposite to the key 20 surface;

b) arranging an elastic waterproof layer 4 on a keyboard frame 3 in a double-material injection or insert molding mode;

c) fixing the keyboard frame 3 and the elastic waterproof layer 4 to the keyboard module 2;

d) assembling the keyboard module 2 with its assembling surface facing the base 1 and the keyboard frame 3 into the accommodating space 10;

e) so that the elastic waterproof layer 4 is tightly attached to the base 1 to form a waterproof ring.

However, the above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, so that all changes in the equivalent techniques and means used in the specification and drawings of the present invention are also included in the scope of the present invention, and it is obvious that the present invention is also encompassed by the present invention. The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
