[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Figure 1 The following is a schematic diagram showing the structure of an embodiment of the thin waterproof keyboard of the utility model. Figure 1 As shown, the thin waterproof keyboard includes: a silicone cover 1, a bottom plate 2 and a circuit board 3.

[0027] Please also refer to Figure 2 The silicone cover 1 includes a key area 11 and an adhesive area 12 arranged around the key area 11. The key area 11 protrudes relative to the adhesive area 12, and, in order to ensure that the keyboard is thin enough, the protrusion corresponds to the thickness of the circuit board 3. The key area 11 includes a key surface 111 and a plurality of key positions 112 protruding relative to the key surface 111, and the silicone cover 1 is integrally formed, so that the silicone cover 1 has good waterproof performance; the adhesive area 12 is bonded to the bottom plate 2, and a cavity is formed between the bottom plate 2 and the key area 11; the circuit board 3 is arranged in the cavity, the top surface of the circuit board 3 abuts the key surface 111, and the bottom surface of the circuit board 3 abuts the bottom plate 2. A corresponding key circuit is arranged on the circuit board 3. When the key position 112 is pressed, it abuts the circuit board 3, and the key circuit corresponding to the key position 112 is connected to generate a corresponding electrical signal.

[0028] Preferably, the bottom plate 2 is a stainless steel bottom plate 2. The silicone cover 1 has a strong adaptability to special environments such as moisture, mold, oily industrial environment, chemical corrosion, etc., and cooperates with the stainless steel bottom plate 2 to improve the keyboard's adaptability to special environments as a whole.

[0029] The novel thin waterproof keyboard of the present embodiment is realized by setting the one-piece formed silicone cover 1 as a key area 11 and an adhesive area 12, bonding the bottom plate 2 and the adhesive area 12 so that a closed cavity just accommodating the circuit board 3 is formed between the key area 11 and the bottom plate 2, and then arranging the circuit board 3 in the closed cavity, thereby achieving a good waterproof effect, so that the keyboard can be used in special environments such as humidity, mold, oily industrial environment, chemical corrosion, etc., and by designing the size of the cavity to match the circuit board 3, the circuit board 3 is just accommodated in the cavity, thereby ensuring that the keyboard is overall thin, more convenient to carry, or convenient to be installed on other devices.

[0030] Furthermore, when the circuit board 3 is installed in the cavity, the top surface of the circuit board 3 abuts against the key surface 111, and the key position 112 protrudes relative to the key surface 111, so that a smaller cavity area is formed between the circuit board 3 and each key position 112. When the key position 112 is pressed, the air in the cavity area is squeezed out. When the key position 112 is released, because the circuit board 3 is in close contact with the key surface 111, the air in the cavity area may not flow back in time, resulting in the pressure in the cavity area being lower than the external pressure, and the key position 112 cannot rebound in time, affecting the normal use of the user. Therefore, based on the above embodiments, in other embodiments, such as Figure 3 and Figure 5 As shown, a plurality of air passages 113 are provided inside the key surface 111 , and each air passage 113 is connected to two adjacent key positions 112 .

[0031] Specifically, by setting an air channel 113 between adjacent key positions 112, when a key position 112 is pressed, the gas can enter the cavity area of ​​other key positions 112 through the air channel 113. When the key position 112 is released, the gas can flow back to the cavity area of ​​the corresponding key position 112 in time through the air channel 113, thereby preventing the key position 112 from not rebounding and affecting user use.

[0032] Further, such as Figure 1 As shown, the thin waterproof keyboard also includes a touchpad assembly 4 and a flat cable 5. A flat cable port 21 is also provided on the bottom plate 2. One end of the flat cable 5 is electrically connected to the touchpad assembly 4, and the other end of the flat cable 5 passes through the flat cable port 21 to be electrically connected to the circuit board 3. The flat cable port 21 is provided with sealant.

[0033] Specifically, by providing the touchpad assembly 4, the thin waterproof keyboard can realize the keyboard and mouse functions. For some special equipment, the touchpad assembly 4 can be directly installed on the corresponding feature equipment without the need to connect a mouse.

[0034] Furthermore, in order to improve the sensitivity and feel of the keys, the thin waterproof keyboard also includes a plurality of key caps 6 , each of which is disposed on a key position 112 .

[0035] Specifically, the key cap 6 is a chocolate key cap, which has a better feel than a silicone key surface, and makes the force on the key cap 6 more uniform, ensuring that the key position 112 can be pressed evenly and accurately realize the corresponding key function.

[0036] Furthermore, in order to improve the practicality of the keyboard in a dark environment, such as Figure 3 and Figure 5 As shown, a avoiding groove 114 is arranged inside the key position 112 , an LED lamp (not shown in the figure) is arranged in the avoiding groove 114 , and a light-transmitting area (not shown in the figure) is arranged on the key cap 6 .

[0037] Specifically, by setting a avoidance groove 114 on the inner side of the key position 112 and installing an LED in the avoidance groove 114, the user can clearly see each key position 112 in a dark environment, thereby improving the practicality of the keyboard in a dark environment and also improving the visual effect when the keyboard is used.

[0038] Furthermore, the light-transmitting area is set to a corresponding symbol shape according to the function realized by each key position 112 .

[0039] Specifically, for example, for the key position 112 corresponding to the letter "A", its light-transmitting area is set to the shape of the letter "A", so that the light emitted by the LED of each key position 112 forms a corresponding letter shape after passing through the light-transmitting area, so as to prompt the user of the function realized by the key position 112.

[0040] Further, such as Figure 2 and Figure 4 As shown, a glue overflow groove 115 is provided on the top surface of the key position 112 , and the key cap 6 is glued to the key position 112 .

[0041] Specifically, by setting a glue overflow groove 115 on the top surface of the key position 112, and then applying glue in the glue overflow groove 115 and bonding it with the key cap 6, the bonding strength between the key position 112 and the key cap 6 is improved to prevent the key cap 6 from falling off.

[0042] Further, such as Figure 2 and Figure 4 As shown, a reinforcing rib 116 is provided in the overflow groove 115 .

[0043] Specifically, in order to reduce the thickness of the keyboard, the overall thickness of the silicone cover 1 is relatively thin, and the thickness of the silicone at the position where the glue overflow groove 115 is set on the key position 112 is even thinner. Therefore, in order to increase the connection strength between the two sides of the glue overflow groove 115, this embodiment sets reinforcing ribs 116 in the glue overflow groove 115 to avoid damage due to the thin thickness of the silicone.

[0044] Further, such as Figure 1 and Figure 5 As shown, a positioning column 117 is disposed inside the key surface 111 , and a positioning hole 31 is disposed at a corresponding position on the circuit board 3 , and the positioning column 117 passes through the positioning hole 31 .

[0045] Specifically, by providing a positioning column 117 on the inner side of the key surface 111 and providing a corresponding positioning hole 31 on the circuit board 3, the circuit board 3 can be installed more quickly and accurately.

[0046] Further, such as Figure 5 As shown, the adhesive area 12 is also provided with a plurality of reserved screw holes 121 .

[0047] Specifically, by providing the reserved screw hole 121, the user can drill holes in the reserved screw hole 121 area according to needs, and then fix it with other devices through screws.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
