Waterproof keyboard 10 includes a base plate 12, a frame member 14, keys 16, and a waterproof member 18. The number of the keys 16 is plural, and the keys are respectively arranged at corresponding positions of the base plate 12. Each key 16 comprises a lifting supporting mechanism 161, an elastic member 162 and a key cap 163; the bottom end of the lifting supporting mechanism 161 passes through the thin film circuit board 19 to be clamped on the bottom plate 12, and the top end of the lifting supporting mechanism 161 is connected to the keycap 163; the elastic member 162 is disposed between the key cap 163 and the base plate 12, and each key 16 further includes a trigger portion 164, and the key cap 163 is pushed down to make the trigger portion 164 touch the switch 191 of the thin film circuit board 19 to issue a control command. The structural members of the key 16 and the thin film circuit board 19 are not limited to the above embodiment.

The frame member 14 is disposed on the base plate 12, and the frame member 14 has a plurality of lattice structures 20. The number and location of the cells 20 corresponds to the number and location of the keys 16 such that each key 16 may be placed within the corresponding cell 20. Generally, the size of the lattice structure 20 is slightly larger than the size of the key 16 to facilitate assembly, however, practical applications are not limited thereto. The flashing 18 further includes a flashing 22, a first support 24, and a second support 26. The waterproof material 22 is laid on the key 16, and is usually made of leather material to provide a better touch feeling, such as plastic leather material or leather material, for the interface of direct operation of the user.

The waterproof material 22 has a plurality of raised structures 28, the number and positions of which correspond to the number and positions of the keys 16. The plurality of raised structures 28 are aligned with the plurality of lattice structures 20, respectively, to overlie the plurality of keys 16. Particularly, the plurality of raised structures 28 may be connected by the bridging layer 30, or the raised structures 28 and the bridging layer 30 may be integrally formed, so as to prevent liquid from leaking to the key 16 under the waterproof material 22. The first support material 24 is provided on the lower surface of the waterproof material 22. The plurality of lattice structures 32 of the first support material 24 are aligned with the plurality of lattice structures 20, respectively, and the structure body of each lattice structure 32 is abutted against the bridging layer 30 of the waterproof material 22.

The plurality of second support members 26 are disposed between the waterproof member 22 and the plurality of keys 16, respectively. Each second support material 26 is placed in a corresponding ridge structure 28 of the waterproof material 22, and is disposed on a corresponding key 16. The shape and size of the second support material 26 are the same or approximate to the shape and size of the inner bottom surface 281 of the corresponding ridge structure 28. The second support 26 may be a thermoset plastic platen (e.g., FR-4) or a polycarbonate Film (PC Film), and is preferably made of a hard material. The upper surface 261 of the second support 26 is attached to the inner bottom surface 281 of the corresponding bump structure 28, and the lower surface 262 of the second support 26 is attached to the key cap 163 of the key 16; the attachment mode can be adhesion or any bonding mode.

As shown in fig. 3, the width W1 of the second support material 26 is preferably greater than the width W2 of the key cap 163 of the key 16, that is, the plurality of sides 263 of the second support material 26 protrude from the plurality of edges 165 of the key cap 163 to support the waterproof material 22; in other words, a gap may be formed between the edge 165 of the key 16 and the inner wall 282 of the bump structure 28, so that the waterproof material 22 has a better degree of freedom to move during the pressing process, thereby avoiding damaging the operation feel of the key 16. Since the second support material 26 is placed in the corresponding raised structure 28, the width W1 of the second support material 26 may be less than or equal to the width W3 of the inner bottom surface 281 of the corresponding raised structure 28. Further, the distance D1 between the edge 165 of the key 16 and the inner wall 282 of the corresponding bump structure 28 may be between 0.4 and 0.6 mm, and the distance D2 between the edge 321 of each grid structure 32 and the inner wall 282 of the corresponding bump structure 28 may be between 1.1 and 1.7 mm; each lattice structure 32 is spaced from the aligned lattice structure 20 by a distance D3 of between 0.3 and 0.5 mm.

Regarding the assembly mode of the waterproof keyboard 10, the first support material 24 may be first attached to the waterproof material 22 by using a hot melt adhesive or other attachment modes, and then sent to a specific mold to be subjected to hot press molding or other modes to align and attach the grid structures 32 of the first support material 24 to the corresponding bump structures 28 of the waterproof material 22; next, the second support material 26 is placed in the raised structure 28 of the waterproof material 22 by using a hot melt adhesive or other attaching means, and the second support material 26 can be attached to the inner bottom surface 281 of the raised structure 28 by using hot press molding or other means; the waterproof member 18 can be manufactured. The frame 14, the keys 16 and the thin film circuit board 19 may be further assembled to the base plate 12; next, a back adhesive is coated on the key caps 163 of the keys 16, and then attached to the second support 26 of the waterproof member 18, thereby completing the assembly of the waterproof keyboard 10.

Referring to fig. 4, fig. 4 is a schematic diagram illustrating components of a waterproof keyboard 10A according to another embodiment of the present utility model. In this embodiment, elements having the same numbers as those of the previous embodiment have the same features and functions, and the description thereof will not be repeated. Waterproof keyboard 10A includes base 12, frame member 14, keys 16, waterproof member 18, and support 34. If the waterproof keyboard 10A is designed in a large size, the area of the waterproof material 22 will be enlarged correspondingly; the flashing 22 is typically made of a soft material and the present utility model may utilize a support 34 between the flashing 22 and the frame member 14 in order to avoid collapsing of a portion of the flashing 22. The support 34 is used to support a weaker section of the waterproofing material 22, such as the middle section of the long axis of the waterproofing material 22. The material, shape, size and position of the supporting member 34 are not limited to the above embodiments, and may be determined according to practical design requirements.

In summary, the waterproof keyboard of the utility model is provided with the second support material made of hard material in the waterproof material, and the second support material is used for supporting the waterproof material made of soft material, so as to avoid collapse and deformation of the waterproof material, and make the waterproof keyboard have better appearance; and the waterproof material cannot collapse and deform, so that higher freedom degree can be provided when a user presses the key, and better operation handfeel is achieved. Furthermore, if the waterproof keyboard is designed in a large size, a supporting piece can be further arranged, and the supporting piece is arranged between the waterproof material and the frame piece, so that the collapse of partial sections of the waterproof material is avoided, and the waterproof keyboard is ensured to have better appearance and operation handfeel.
