Description

Technical Field

[0001] This utility model relates to the field of keyboards, and in particular to a keyboard based on PET membrane switches. Background Technology

[0002] A keyboard is an input device that enables human-computer interaction by triggering electronic signals through key presses. It is one of the core peripherals of electronic products such as computers, mobile phones, and industrial control equipment. PET membrane switch-based keyboards are tactile keyboards that use PET as the core circuit carrier and achieve key functions through a combination of multiple flexible films. They have significant advantages such as being thin, flexible, weather-resistant, long-lasting, and customizable, making them a commonly used type of keyboard today.

[0003] In existing keyboards based on PET mortise switches, support pads are often extended onto the keyboard to improve operator hand comfort. However, in existing keyboards, the position of these support pads is fixed and cannot be adjusted relative to the keyboard body, resulting in limited flexibility and adaptability. Furthermore, the support pads only provide auxiliary support and do not offer cooling for the hands in hot weather, rendering their effectiveness limited. Additionally, existing keyboards use flip-up support blocks to tilt the keyboard, but these blocks are prone to damage and detachment, leading to inconsistent stability. Utility Model Content

[0018] 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.

[0019] like Figures 1-5 As shown, a keyboard based on a PET membrane switch includes a base shell 1, inside which a PET membrane switch 2 is located. A cover plate 3 is connected to the base shell 1, and buttons 4 are mounted on the cover plate 3. The lower surface of the base shell 1 has a first anti-slip support block 5 and a second anti-slip support block 6, and a cooling support assembly 7. The second anti-slip support block 6 has a storage groove 8. A threaded connector 9 is located on the base shell 1 at the second anti-slip support block 6, and a supporting rubber head 10 is mounted on the threaded connector 9. The supporting rubber head 10 has a groove 11, and the threaded connector 9 is threadedly connected to the base shell 1, passing through the storage groove 8 on the second anti-slip support block 6. The PET membrane switch 2 has a spring-loaded protrusion, and the buttons 4 correspond one-to-one with the spring-loaded protrusions on the PET membrane switch 2.

[0020] When using the keyboard, it is placed on the first anti-slip support block 5 and the second anti-slip support block 6 on the lower surface of the bottom shell 1. After connecting the cable, the keyboard is activated by striking the button 4 on the cover plate 3 to touch the PET membrane switch 2, thereby sending an electrical signal to achieve the purpose of input. If an auxiliary support structure is needed during keyboard use, the cooling support component 7 can be installed on the bottom shell 1 of the keyboard. The cooling support component 7 provides auxiliary support for the hand, improving the comfort of using the keyboard. When needed, the cooling support component 7 can be adjusted to increase the flexibility and adaptability of use. When using the keyboard in hot weather, water can be injected into the support component of the cooling support component 7 to cool it down.

[0021] When using the keyboard, to change the keyboard's tilt angle, insert a tool into the groove 11 on the support rubber head 10, rotate the support rubber head 10, and the threaded connector 9 rotates in the storage groove 8 on the second anti-slip support block 6, thereby moving relative to the bottom shell 1 to change the purpose of the support rubber head 10 and thus change the keyboard's tilt angle. When the keyboard needs to be placed horizontally, rotate the threaded connector 9 until the support rubber head 10 is retracted into the storage groove 8. At this time, when the keyboard is placed, it is supported only by the first anti-slip support block 5 and the second anti-slip support block 6, and the keyboard can be used in a horizontal state.

[0022] According to the above implementation scheme, the cooling support assembly 7 includes a fixing strip 701, a movable plate 702, and a limiting block 703. The fixing strip 701 has grooves at both ends, and connecting screws are installed in the grooves. The fixing strip 701 is fixed to the bottom shell 1 by the connecting screws. The fixing strip 701 has movable holes. The movable plate 702 is fixedly connected to the limiting block 703, and the movable plate 702 is located in the movable holes on the fixing strip 701, contacting the bottom shell 1. The cooling support assembly 7 also includes a support base 704, a rotating connecting base 705, a water injection connector 706, and an end cap 707. The support base 704 is fixedly connected to the rotating connecting base 705, and the rotating connecting base 705 is rotatably connected to the movable plate 702. The support base 704 has a cavity. The water injection connector 706 is fixed to the end of the support base 704 and communicates with the cavity inside the support base 704. The end cap 707 is connected to the water injection connector 706.

[0023] When installing the cooling support assembly 7, the movable plate 702 is placed in the through hole on the fixed strip 701. The fixed strip 701 is installed onto the base shell 1 using connecting screws. The end of the movable plate 702 is provided with a support base 704 via a rotating connecting seat 705. After the cooling support assembly 7 is installed, it can be used. During use, the support base 704 provides auxiliary support for the hands, improving the comfort of using the keyboard. At the same time, the movable plate 702 can move on the fixed strip 701, thereby changing the distance between the support base 704 and the base shell 1, which facilitates the adjustment of the position of the support base 704 according to the actual situation, making it highly adaptable. When the keyboard is used at an angle, the end of the movable plate 702, in conjunction with the support rubber head 10, supports the keyboard. The support base 704 rotates relative to the movable plate 702 via the rotating connecting seat 705, without affecting the horizontal placement of the support base 704. When using the device in hot weather, the end cap 707 can be removed, and the keyboard can be held vertically with the water inlet 706 facing upwards. Water can then be poured into the support base 704 through the water inlet 706, and the end cap 707 can be closed before use. At this time, the water inside the support base 704 can effectively absorb the heat from the hands to cool them down, preventing discomfort caused by sweaty hands and further improving work comfort. When the water in the support base 704 is no longer needed, the end cap 707 can be opened and the water in the support base 704 can be poured out. The structure is simple and the effect is good.

[0024] It should be noted that, through the cooling support component 7, the support base 704 is mounted on the movable plate 702 via the rotating connecting seat 705, ensuring horizontal placement when the keyboard is tilted. The movable plate 702 can move on the fixing strip 701, facilitating changes in the distance between the support base 704 and the keyboard body, thus improving flexibility and adaptability. The support base 704 is hollow inside, and when used with the water injection connector 706 and end cap 707, water can be injected into the support base 704, giving it a better heat absorption effect. This makes the cooling support component 7 more versatile. Through the threaded connector 9 and the support rubber head 10, the support rubber head 10 has a groove 11. The position of the support rubber head 10 relative to the bottom shell 1 can be adjusted using the threaded connector 9, which adjusts the keyboard tilt angle while ensuring stability after adjustment and preventing it from falling off. At the same time, the threaded connector 9 and the support rubber head 10 can be screwed into the storage groove 8 without affecting the horizontal placement of the keyboard.

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.
