Description

Technical Field

[0001] This utility model relates to the field of keyboard technology, and in particular to a waterproof and dustproof keyboard. Background Technology

[0002] In modern office and daily life, keyboards, as indispensable computer input devices, are used in increasingly diverse scenarios. From everyday office desks to home entertainment environments, from public places like cafes to mobile outdoor work environments, keyboards are frequently exposed to various complex environments. However, the traditional keyboards widely used in the market today have significant shortcomings in terms of waterproofing and dustproofing, making it difficult to meet users' needs in different scenarios. The structural design of most traditional keyboards results in numerous gaps between the keycaps and the keyboard body. While these gaps facilitate flexible key operation, they also become channels for dust, debris, and liquid intrusion. In mechanical keyboards, there are gaps at the interface between the switches and the PC mounting plate, which cannot effectively prevent dust and water from entering. Therefore, existing traditional keyboards, due to their lack of waterproofing and dustproofing, exhibit significant vulnerability to various liquid splashes and dust intrusion during daily use, limiting their stable application in many scenarios. There is an urgent need for a new type of keyboard with good waterproofing and dustproofing performance to solve these problems and meet users' growing demands for keyboard reliability and durability. To this end, we propose a waterproof and dustproof keyboard. Utility Model Content

[0003] The main purpose of this utility model is to provide a waterproof and dustproof keyboard, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A waterproof and dustproof keyboard includes a bottom shell, a PCB board is mounted on the inner bottom of the bottom shell, a PC positioning plate is mounted on the PCB board, a switch is embedded and snapped into the PC positioning plate, a protective structure is attached to the upper surface of the PC positioning plate, and keycaps are snapped onto each switch.

[0006] Preferably, the protective structure includes a silicone membrane, a perimeter enclosure seal installed around the silicone membrane, a lifting ring installed on the perimeter enclosure seal, a shaft hole opened in the silicone membrane, and a shaft seal fixed around the shaft hole.

[0007] Preferably, the enclosure side seal is tightly attached to the inner perimeter of the bottom shell to form a compression seal, and the upper edge of the enclosure side seal is four millimeters higher than the upper surface of the silicone film.

[0008] Preferably, the shaft hole is provided in multiple parts according to the shape of the shaft body, and the shaft body is nested in the shaft hole. The shaft side seal is tightly attached to the periphery of the shaft body, and the upper surface of the shaft side seal is three millimeters higher than the upper surface of the silicone film.

[0009] Preferably, the shaft side seals are all located on the inner side directly below the corresponding keycaps, and two lifting rings are provided on each of the four sides of the enclosure side seals.

[0010] Preferably, a USB connector is electrically mounted on the PCB board, and a preset socket is provided on the surface of the bottom shell behind the USB connector.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this invention, the keyboard features a protective structure. The groove formed by the combination of the silicone film, the switch edge seal, and the surrounding edge seal can hold a certain amount of water and provide a certain degree of sealing when water is splashed. This prevents water from flowing into the PCB board through the gaps between the PC positioning plate and the switches, as well as between the PC positioning plate and the bottom shell, which could cause short circuits and key malfunctions. Additionally, during daily use, the gaps between the keycaps allow external dust to easily enter, which falls directly onto the silicone film. For subsequent cleaning, the keycaps are removed, the keyboard is turned upside down, and the protective structure is slowly peeled off using the four lifting rings to separate it from the PC positioning plate. After separation, the protective structure can be cleaned by washing with water, and after drying, it can be reinstalled on the PC positioning plate. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Example 1:

[0021] like Figure 1-5 As shown, a waterproof and dustproof keyboard includes a bottom shell 1, a PCB board 2 installed on the inner bottom of the bottom shell 1, a PC positioning plate 3 installed on the PCB board 2, a switch 4 embedded and snapped into the PC positioning plate 3, a protective structure 5 attached to the upper surface of the PC positioning plate 3, and keycaps 6 snapped into each switch 4.

[0022] The protective structure 5 includes a silicone membrane 51, a perimeter sealing edge 52 installed around the silicone membrane 51, a lifting ring 53 installed on the perimeter sealing edge 52, a shaft hole 55 opened in the silicone membrane 51, and a shaft sealing edge 54 fixed around the shaft hole 55.

[0023] Specifically, the shaft edge seal 54 is tightly nested around the shaft body 4, sealing the edge of the shaft body to prevent water stains and dust from entering through the gap between the shaft body 4 and the PC positioning plate 3. At the same time, the shaft edge seal 54, the silicone film 51 and the enclosure edge seal 52 form an enclosure storage structure that can store enough spilled water to prevent water from seeping in.

[0024] The enclosure side seal 52 is tightly attached to the inner perimeter of the bottom shell 1 to form a compression seal, and the upper edge of the enclosure side seal 52 is four millimeters higher than the upper surface of the silicone film 51.

[0025] Specifically, the edge seal 52 mainly stores spilled water by being higher than the silicone film 51, and the edge seal 52 is close to the inner edge of the bottom shell 1 to form a seal, preventing water and dust from entering the core PCB board 2 layer, thereby effectively protecting the internal circuit.

[0026] Multiple shaft holes 55 are provided according to the shape of the shaft body 4. The shaft body 4 is nested in the shaft hole 55. The shaft side seal 54 is tightly attached to the periphery of the shaft body 4, and the upper surface of the shaft side seal 54 is three millimeters higher than the upper surface of the silicone film 51.

[0027] Specifically, the shaft hole 55 is set to match the different shaft bodies 4, and the shaft edge seal 54 on the shaft hole 55 is also changed accordingly. When the shaft edge seal 54 is inserted into the periphery of the shaft body 4, it will wrap around the shaft body 4 and press the edge with a certain pressure to seal it. Similarly, the upper surface of the shaft edge seal 54 is set to be three millimeters higher than the upper surface of the silicone film 51 so that excess water can be stored on the silicone film 51 and prevent moisture from entering the interior through its edge seal for a long time.

[0028] The side seals 54 are all located on the inner side directly below the corresponding keycaps 6, and there are two lifting rings 53 on each of the four sides of the side seals 52.

[0029] Specifically, when water is splashed on keycap 6, the water will flow through the edge of keycap 6 into the area around the lower switch edge seal 54, reducing the amount of water remaining in the gap between the switch edge seal 54 and the switch body 4.

[0030] A USB connector 21 is electrically mounted on the PCB board 2, and a preset socket 11 is provided on the surface of the bottom shell 1 behind the USB connector 21.

[0031] Specifically, the USB cable can be inserted into the USB connector 21 through the preset jack 11, and then the other end can be connected to the computer.

[0032] It should be noted that this utility model is a waterproof and dustproof keyboard. In daily use, if water or tea is accidentally spilled onto the keycaps 6 and slides down onto the silicone membrane 51, the water can be contained by the surrounding edge seal 52 and the inner axis edge seal 54 of the silicone membrane 51. This prevents water from entering the PCB board 2 and causing short circuits and keyboard malfunctions. The axis edge seal 54 encapsulates the area around the axis 4, and the surrounding edge seal 52 encapsulates the gap between the PC positioning plate 3 and the bottom shell 1, effectively sealing the gap and preventing water seepage. At the same time, it prevents dust from entering. To clean the dust on the silicone membrane 51, simply remove the keycaps, turn the keyboard upside down, and then slowly peel off the edges of the protective structure 5 using the lifting rings 53 on all four sides to separate it from the PC positioning plate 3. After separation, the protective structure 5 can be cleaned by washing with water. After drying, it can be reinstalled on the PC positioning plate 3 for reuse, thus avoiding the problem of cleaning the gap between the axis 4.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
