Description

Technical Field

[0001] This invention relates to the field of computer keyboard technology, and more particularly to a composite computer input keyboard. Background Technology

[0002] As a core device for human-computer interaction, computer input keyboards are indispensable computer accessories in scenarios such as office work, entertainment, and industrial control. With the development of computer technology and the diversification of user needs, composite computer input keyboards have integrated one or more functional structures such as touchpad, numeric keypad, customizable function key area, and shortcut operation module on the basis of traditional alphanumeric keypad. At the same time, they also take into account additional requirements such as dust protection and ergonomic support. With the characteristics of multi-functional integration and ease of use, they are widely used in desktop computers, portable terminal accessories, industrial control terminals and other scenarios, becoming the mainstream development direction of keyboard products.

[0003] However, some multi-function computer keyboards come with a dust cover, which is used when not in use to prevent dust from accumulating between the keycaps and key holes. But during use, it's easy to forget to use the cover when leaving your seat, which reduces the keyboard's lifespan. In addition, some office workers are increasingly prone to tenosynovitis due to prolonged working hours. Currently, some office workers use wrist rests to reduce wrist strain, but these rests are small and lightweight, making them easy to lose and inconvenient. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technical problems in the prior art by proposing a composite computer input keyboard.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A composite computer input keyboard includes a cover plate and a keyboard body. The keyboard body has a first mounting slot inside, and a motor is fixedly connected inside the first mounting slot. A rotating rod is fixedly connected to the output end of the motor. The rotating rod is driven by a mounting rod, which is fixedly connected to a first bevel gear. The first bevel gear meshes with a second bevel gear, which is fixedly connected to a connecting rod. Connecting blocks are symmetrically fixedly connected to the surface of the connecting rod, and the connecting blocks are fixedly connected to the cover plate. A threaded rod is fixedly connected to the rotating rod, and a sliding plate is threadedly connected to the threaded rod. The sliding plate is slidably connected to a slot, and the slot is fixedly connected to a support rod. The support rod is fixedly connected to a pull plate, and the pull plate is slidably connected to a storage compartment. A connecting box is piped into the storage compartment, and a flexible support plate is slidably connected to the connecting box. A tension spring is fixedly connected to one side of the flexible support plate, and the end of the tension spring away from the flexible support plate is fixedly connected to the connecting box.

[0006] The above technical solution further includes: A fixing block is fixedly connected to the side of the keyboard body. The fixing block is rotatably connected to the connecting rod. A square groove is opened on the side of the keyboard body. The square groove is rotatably connected to the first bevel gear. A belt is driven to the rotating rod. An installation rod is driven to the end of the belt away from the rotating rod.

[0007] A keyboard keypad is located on top of the keyboard body.

[0008] A rod is fixedly connected inside the groove, and the rod is slidably connected to the sliding plate.

[0009] The pull plate contains a chemically stable inert gas.

[0010] By incorporating a chemically stable inert gas inside the pull plate, the inert gas's non-reactive, easily controllable shape, and stable support force provides stable power support for the extension and retraction of the wrist pad. This ensures that the support height and shape remain fixed after the soft support plate extends, avoiding support failure caused by gas leakage or deformation. At the same time, the inert gas's stable chemical properties prevent deterioration or corrosion during long-term use, effectively improving the stability and durability of the wrist pad's telescopic structure and ensuring the continuity and reliability of wrist support.

[0011] The surface of the sliding plate is provided with a second setting groove, which is fixedly connected to the connecting box.

[0012] By setting a second setting groove on the surface of the sliding plate and fixing the second setting groove to the connecting box, the integrated linkage between the connecting box and the sliding plate is realized. This allows the sliding action of the sliding plate to be accurately transmitted to the connecting box, ensuring smoother flow and transmission of inert gas between the pull plate and the connecting box. It also avoids gas transmission obstruction caused by loose connection or misalignment, thereby ensuring the synchronicity and accuracy of the extension and retraction of the soft support plate. This allows the extension and retraction of the wrist pad to be precisely linked with the opening and closing of the keyboard dust cover, improving the transmission coordination and operation smoothness of the overall structure.

[0013] A support plate is fixedly connected to the surface of the storage compartment.

[0014] By fixing a support plate to the surface of the storage chamber, the support plate provides a stable structural support for the storage chamber, effectively dispersing the internal pressure generated by the filling and releasing of inert gas. This prevents the storage chamber from deforming and cracking due to long-term pressure. At the same time, the support plate can fix the installation position of the storage chamber, preventing it from shifting or shaking during equipment operation. This ensures the stability of the inert gas storage and transmission structure, provides a solid structural foundation for the normal expansion and contraction of the wrist pad, and extends the overall service life of the equipment.

[0015] The surface of the flexible support plate is provided with a soft pad to support the wrist.

[0016] By incorporating a soft pad on the surface of the support board to support the wrist, the flexible contact characteristics of the pad allow for a closer fit between the wrist and the support board. This effectively disperses the localized pressure on the wrist during prolonged typing, relieving fatigue in the wrist muscles and joints, and reducing the probability of tenosynovitis caused by long hours of office work. At the same time, the soft pad reduces direct friction between the wrist and the hard board, improving the comfort of wrist support and making the ergonomic protection effect of this design more significant, thus meeting the needs of long hours of office work.

[0017] The keyboard keypad has multiple sets of keys on its surface.

[0018] Through the synchronized design of the dust cover and wrist rest, the dust cover can precisely avoid multiple sets of keys when opening and closing, allowing the keys on the keypad to be completely exposed and unobstructed during use, ensuring normal input operation for the staff. When not in use, the dust cover can completely cover the surface of the keypad, providing comprehensive protection for multiple sets of keys, effectively preventing dust and impurities from entering the gaps between the keycaps and key holes, avoiding problems such as key jamming and poor contact, improving the sensitivity and stability of key use, and extending the service life of the keyboard keypad and the entire device.

[0019] The present invention has the following beneficial effects: 1. In this invention, the automatic opening and closing control of the dust cover is achieved through the linkage of the sensor motor, transmission components and gear meshing structure. There is no need for staff to manually operate the dust cover to close and open. From a technical point of view, this completely avoids the problem of existing keyboards where dust enters the gap between the keycaps and key holes due to people forgetting to close the dust cover, causing keyboard failure. It effectively reduces the corrosion of dust on the internal structure of the keyboard, significantly improves the stability of the composite computer input keyboard, and extends the overall service life of the keyboard.

[0020] 2. In this invention, the linkage transmission structure of the dust cover is integrated with the automatic telescopic expansion structure of the wrist pad. The rotation of the transmission component drives the flow of inert gas between the cavities, realizing the automatic ejection and retraction of the wrist pad. There is no need for staff to place and take out the wrist pad separately, which solves the problems of small size and easy loss of existing independent wrist pads. At the same time, it provides stable wrist support for staff who type for long periods of time, effectively relieves wrist fatigue, reduces the probability of tenosynovitis caused by long-term office work, and improves the ergonomic user experience of the composite computer input keyboard.

[0026] In one embodiment, a keyboard keypad 7 is provided on top of the keyboard body 4.

[0027] In one embodiment, for the aforementioned groove 24, a rod 22 is fixedly connected inside the groove 24, and the rod 22 is slidably connected to the sliding plate 23.

[0028] In one embodiment, the pull plate 18 is provided with a chemically stable inert gas inside.

[0029] In this embodiment, by setting a chemically stable inert gas inside the pull plate 18, the characteristics of the inert gas—no chemical reaction, easy shape control, and stable support force—provide stable power support for the extension and retraction of the wrist pad. This ensures that the support height and shape of the soft support plate 21 remain fixed after extension, avoiding support failure caused by gas leakage or deformation. At the same time, the inert gas is chemically stable and will not deteriorate or corrode due to long-term use, effectively improving the stability and durability of the wrist pad's telescopic structure and ensuring the continuity and reliability of wrist support.

[0030] In one embodiment, the slide plate 23 has a second mounting groove 9 on its surface, and the second mounting groove 9 is fixedly connected to the connecting box 16.

[0031] In this embodiment, by setting a second setting groove 9 on the surface of the slide plate 23 and fixing the second setting groove 9 to the connecting box 16, the integrated linkage between the connecting box 16 and the slide plate 23 is realized, so that the sliding action of the slide plate 23 can be accurately transmitted to the connecting box 16, ensuring smoother flow transmission of inert gas between the pull plate 18 and the connecting box 16, avoiding gas transmission obstruction caused by loose connection or misalignment, thereby ensuring the synchronicity and accuracy of the extension and retraction of the soft support plate 21, so that the extension and retraction of the wrist pad can be accurately linked with the opening and closing of the keyboard dust cover, improving the transmission coordination and operation smoothness of the overall structure.

[0032] In one embodiment, a support plate 20 is fixedly connected to the surface of the storage compartment 19.

[0033] In this embodiment, by fixing a support plate 20 to the surface of the storage chamber 19, the support plate 20 provides a stable structural support for the storage chamber 19, effectively dispersing the internal pressure generated by the filling and releasing of inert gas in the storage chamber 19, preventing the storage chamber 19 from deforming or cracking due to long-term pressure. At the same time, the support plate 20 can fix the installation position of the storage chamber 19, preventing it from shifting or shaking during equipment linkage, ensuring the stability of the inert gas storage and transmission structure, providing a solid structural foundation for the normal extension and contraction of the wrist pad, and extending the overall service life of the equipment.

[0034] In one embodiment, the soft support plate 21 described above has a soft pad on its surface to support the wrist.

[0035] In this embodiment, by setting a soft pad on the surface of the soft support plate 21 to support the wrist, the soft pad's flexible contact characteristics allow the wrist to fit more closely with the soft support plate 21. This effectively disperses the local pressure exerted on the wrist during long-term typing, relieves fatigue in the wrist muscles and joints, and reduces the probability of workers developing tenosynovitis due to prolonged office work. At the same time, the soft pad reduces direct friction between the wrist and the hard plate, improving the comfort of wrist support and making the ergonomic protection effect of this design more significant, thus meeting the needs of long-term office work.

[0036] In one embodiment, the keyboard keypad 7 has multiple sets of keys on its surface.

[0037] In this embodiment, the synchronous linkage design of the dust cover and wrist rest enables precise avoidance of multiple sets of keys when the dust cover opens and closes, allowing the keys of the keypad 7 to be completely exposed and unobstructed during use, ensuring normal input operation for the staff. When not in use, the dust cover can completely cover the surface of the keypad 7, providing comprehensive protection for multiple sets of keys, effectively preventing dust and impurities from entering the gaps between the keycaps and key holes, avoiding problems such as key jamming and poor contact, improving the sensitivity and stability of key use, and extending the service life of the keyboard keypad and the overall device.

[0038] The working principle of the composite computer input keyboard in this invention is as follows: First, if the operator wants to use the keyboard, the output end of control 13 is rotated. Then, the output end of 13 drives 12 to rotate. Then, 12 drives 10 to rotate via 11. Then, the rotation of 10 drives 41 to rotate. Then, the rotation of 41 engages with 42. Then, 42 drives 3 to rotate. Then, 2, which is symmetrically arranged on the surface of 3, drives 1 to rotate, thereby exposing the keys on the surface of 7 for use. At the same time, when 12 rotates, it drives 14 to rotate. Then, the rotation of 14 drives 23 to slide. Then, the sliding of 23 drives 19 to move. However, 15 is fixed to the side of 24, so 15 drives 18 to compress the inert gas inside 19, thereby allowing the inert gas to enter the interior of 16. After the gas enters the interior of 16, it pushes up 21. Then, 21 pulls 17, increasing the pulling force of 17. At this time, 21 slides along the inner side of 16, thus providing a place for the operator to type.

[0039] When not in use, the output of 13 is rotated in reverse, then 12 drives 14 to rotate, and when 14 rotates, 23 re-enters 24. The interlayer between 18 and 19 gradually increases, and 17 pulls 21 to squeeze the inert gas inside 16 back into 19. Before 23 completely enters 24, 21 completely enters 16. The rotation of 12 will use 11 to drive 10 to rotate, and then 10 drives 41 and 42 to mesh. Then 32 will drive 2 on the surface of 3 to cover 1 on the surface of 7.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
