Abstract
Description
Technical Field
[0001] The invention relates to the technical field of network hardware, in particular to a keyboard connecting device and a keyboard. Background Art
[0002] As electronic games become increasingly popular, the design and function optimization of keyboards, as one of the core devices for game control, are crucial to improving the player experience. Especially in high-intensity game competitions, players tend to adopt specific operating habits, such as the "standard" layout of using the left hand to control the keyboard and the right hand to control the mouse, in order to maximize operating efficiency and reaction speed. In this operating mode, the frequency of use of keys on the keyboard is highly concentrated in several key areas required for game control, while a large number of non-essential keys on traditional full-size keyboards are often ignored, which has led to the birth of one-handed keyboards designed specifically for games.
[0003] As the leader in this field, one-handed mechanical keyboards have won the favor of many game enthusiasts with their precise positioning, fast-response mechanical keys, and key layout optimized for games. However, in actual use, players' hands are prone to sweating, which may not only interfere with the accurate triggering of keys and affect the accuracy of game operations, but also the long-term accumulation of sweat may corrode the surface material of the keyboard, shorten the service life of the keyboard, and even affect the appearance. In addition, players' operating habits are not static. They often adjust their postures according to the game situation and personal comfort, including frequently shaking or rotating their wrists in order to achieve the best operating state. However, the existing one-handed mechanical keyboard design does not fully take this dynamic demand into account. The palm rest cannot be adaptively adjusted according to the player's hand posture, causing players to have to frequently manually adjust the keyboard position to maintain a comfortable operating angle. This not only interrupts the smoothness of the game, but may also cause fatigue in the wrist and arm.

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] See also Figure 1 - Figure 8 The present invention provides a technical solution: a keyboard connection device and a keyboard, comprising a shell 1, a storage compartment 6 is provided on the top of the shell 1, an air bag 10 is provided on the inner wall of the storage compartment 6, an air inlet pipe 12 and an air outlet pipe 13 are fixedly installed on the side wall of the air bag 10, an air inlet hole 7 and an air outlet hole 8 are provided on the side wall of the shell 1, the inner walls of the air inlet hole 7 and the air outlet hole 8 are plugged with the air inlet pipe 12 and the air outlet pipe 13, a rubber sheet 4 is clamped on the side wall of the shell 1 near the air inlet hole 7, a hand rest 3 is fixedly installed on the top of the rubber sheet 4, a plurality of connection holes 11 are provided on the inner wall of the air bag 10, and keys 2 are plugged into the inner walls of the connection holes 11.
[0019] It should be noted that the accommodation chamber 6 is provided on the top of the housing 1 and is used to install and fix the airbag 10, providing a closed and stable space for the airbag 10 to ensure that it can work normally; Furthermore, the airbag 10 is arranged on the inner wall of the accommodation chamber 6, and exchanges gas with the inside of the palm rest 3 through the air inlet pipe 12 and the air outlet pipe 13. When the user presses the button 2, the gas inside the airbag 10 is blown to the palm of the user through the palm rest 3; Furthermore, the air inlet pipe 12 and the air outlet pipe 13 are respectively fixedly installed on the side walls of the airbag 10. The air inlet pipe 12 is used to inflate the airbag 10, and the air outlet pipe 13 is used to discharge the gas in the airbag 10, thereby realizing the connection between the airbag 10 and the external environment, making it convenient for users to perform inflation and deflation operations.
[0020] Furthermore, the rubber sheet 4 is clamped on the side wall of the shell 1 near the air inlet 7, serving as a supporting part of the palm rest 3, and at the same time has a certain sealing property to prevent gas leakage from the air inlet 7, thereby enhancing the stability of the palm rest 3 and ensuring the sealing property of the airbag 10.
[0021] See also Figure 4 , Figure 5The present invention provides a technical solution: a keyboard connecting device and a keyboard, comprising a connecting seat 21 fixedly installed at the bottom of a palm rest 3, a supporting plate 20 fixedly installed at the bottom of the connecting seat 21, a connecting shaft 22 fixedly installed at the bottom of the supporting plate 20, a gear 19 fixedly installed at the center of the surface of the connecting shaft 22, a screw rod 25 meshingly connected at the bottom of the gear 19, a first fixed seat 16 fixedly installed at the side end of the screw rod 25, a first support rod 17 rotatably installed on the outer wall of the screw rod 25 close to the first fixed seat 16, a fixing ring 18 fixedly installed on the top of the first support rod 17, a second support rod 23 fixedly installed on the side wall of the fixing ring 18, and a second fixed seat 24 fixedly installed at the bottom of the second support rod 23.
[0022] It should be noted that the palm rest 3 directly contacts the user's wrist, provides comfortable support for the user, reduces wrist fatigue, and can better fit the user's wrist through adaptive adjustment to enhance the gaming experience; Furthermore, the gear 19 is fixedly mounted at the center of the surface of the connecting shaft 22, meshing with the screw 25, transmitting the rotational force, and realizing the adjustment of the tilt angle of the hand rest 3, which can accurately respond to the swing of the wrist; When the user swings his wrist during the game, the gear 19 on the connecting shaft 22 will rotate according to the swing direction and amplitude of the wrist. This rotation will be transmitted to the screw 25, causing it to move along a specific trajectory. At the same time, the first support rod 17 will rotate accordingly under the support of the screw 25, thereby changing the left and right tilt amplitude of the palm rest 3. The fixing ring 18 and the second support rod 23 allow the palm rest 3 to swing back and forth.
[0023] See also Figure 7 The present invention provides a technical solution: a keyboard connecting device and a keyboard, comprising a second connecting tube 14 fixedly installed inside the side wall of a rubber sheet 4 close to a shell 1, a limiting column 26 fixedly installed on the inner wall of the second connecting tube 14, a pillar 27 fixedly installed on the inner wall of the limiting column 26, a second chuck 28 slidably installed on the outer wall of the pillar 27, a first chuck 15 fixedly installed on the end of the pillar 27, an outer wall of the first chuck 15 slidably installed on the inner wall of a chuck slot 34 opened inside the first connecting tube 9, a chuck slot 33 opened on the side wall of the first chuck 15, a spring 31 fixedly installed on the inner wall of the chuck slot 33, and a chuck slot 32 fixedly connected to the other end of the spring 31.
[0024] It should be noted that the support column 27 is fixedly mounted on the inner wall of the limiting column 26 and serves as a sliding track for the second chuck 28; Furthermore, the first chuck 15 is fixedly mounted on the end of the support 27, and is slidably mounted on the inner wall of the chuck slot 34 inside the first connecting tube 9, and cooperates with the chuck slot 34 to achieve the connection between the hand rest 3 and the housing 1; Furthermore, the spring 31 is fixedly mounted on the inner wall of the column slide slot 33 to provide elastic force for the column 32, ensuring that the column 32 can be tightly fixed on the inner wall of the chuck slide slot 34. The second chuck 28 is slidably mounted on the outer wall of the support 27 to unlock the fixation between the first chuck 15 and the first connecting pipe 9 .
[0025] See also Figure 1 , Figure 6 The present invention provides a technical solution: a keyboard connecting device and a keyboard, including a rotating shaft 38 fixedly installed at the bottom of the shell 1, a first connecting arm 36 rotatably installed on the inner wall of the rotating shaft 38, a sliding shaft 37 rotatably installed at the bottom of the first connecting arm 36, and a bottom plate 35 slidably installed at the bottom of the sliding shaft 37.
[0026] It should be noted that the first connecting arm 36 is rotatably mounted on the inner wall of the rotating shaft 38, connecting the housing 1 and the sliding shaft 37, so as to adjust the tilt angle of the housing 1. When the hand rest 3 swings back and forth, the housing 1 is driven to move in the opposite direction, thereby changing the tilt angle of the housing 1. Furthermore, through the swinging of the palm rest 3 and the sliding adjustment of the sliding shaft 37 on the top of the bottom plate 35, the user can conveniently adjust the tilt angle of the housing 1 to improve the comfort and convenience of use.
[0027] See also Figure 6 The present invention provides a technical solution: a keyboard connecting device and a keyboard, including a first limiting groove 41, a second limiting groove 42, and a third limiting groove 43 are opened on the top of a bottom plate 35, a second connecting arm 39 is slidably installed on the inner wall of the second limiting groove 42, and the top of the second connecting arm 39 is rotatably connected to the bottom of the shell 1, and a third connecting arm 40 is slidably installed on the inner wall of the third limiting groove 43, and the top of the third connecting arm 40 is rotatably connected to the bottom of the shell 1.
[0028] It should be noted that the bottom plate 35 is located at the bottom of the overall structure and serves as a supporting base. At the same time, the multiple limit grooves thereon are used to limit and guide the movement of other connecting arms, thereby achieving tilt angle adjustment and stable support of the housing 1.
[0029] See also Figure 7 The present invention provides a technical solution: a keyboard connecting device and a keyboard, including a first connecting tube 9 having a second stop column 30 slidably mounted on the side wall, a second connecting tube 14 having a first stop column 29 fixedly mounted on the side wall, and the first stop column 29 abuts against the second stop column 30.
[0030] It should be noted that: the first connecting tube 9 is a part of the connection between the hand rest 3 and the housing 1, and a second abutment column 30 is slidably mounted on its side wall, corresponding to the first connecting tube 9, and fixedly mounted on the side wall of the housing 1, and a first abutment column 29 is fixedly mounted on its side wall, and an elastic device (not shown in the figure) is provided on the inner wall, which is used to abut against the second abutment column 30 to realize the clamping function of the hand rest 3; When the hand rest 3 is mounted on the housing 1, the second abutting column 30 abuts against the first abutting column 29. Since an elastic device (not shown in the figure) is provided on the inner wall of the first abutting column 29, when the second abutting column 30 abuts against it, the elastic device (not shown in the figure) is compressed, generating a certain resistance, so that the hand rest 3 is stably clamped on the side wall of the housing 1. When the palm rest 3 needs to be removed, the user needs to push the palm rest 3 toward the outer shell 1 with force. This thrust causes the second support column 30 to further compress the elastic device of the inner wall of the first support column 29 (not shown in the figure). At the same time, the second chuck 28 inside the palm rest 3 begins to contact the clamping column 32. As the thrust increases, the arc-shaped surface of the second chuck 28 begins to squeeze the clamping column 32, causing it to gradually enter the clamping column slot 33. When the clamping column 32 completely enters the clamping column slot 33, the clamping relationship between the palm rest 3 and the outer shell 1 is released, and the palm rest 3 can be easily removed at this time.
[0031] See also Figure 1 The present invention provides a technical solution: a keyboard connection device and a keyboard, including a palm rest 3 having tiny air holes on its surface for blowing air, and the surface material of the palm rest 3 is non-slip rubber.
[0032] It should be noted that: when the user presses the button 2, the compression mechanism of the airbag 10 is triggered, so that the gas inside the airbag 10 is discharged through the tiny pores on the surface of the palm rest 3, and a short blowing action is performed on the palm; Furthermore, the blowing function can quickly remove the sweat on the surface of the palm, keeping the palm dry and improving the user's overall experience.
[0033] See also Figure 8 The present invention provides a technical solution: a keyboard connection device and a keyboard, comprising a housing 1 on which a touch panel 5 is fixedly mounted, and the surface of the touch panel 5 is a frosted texture.
[0034] It should be noted that the frosted surface has a better anti-slip effect, especially when the hands are wet or sweaty, and can effectively prevent accidental sliding or misoperation when the fingers slide on the touch pad 5, thereby improving the safety of use.
[0035] The device utilizes the combination of the airbag 10 and the palm rest 3. When the user presses the button 2, the gas inside the airbag 10 is blown to the palm of the user's hand, which effectively solves the problem that sweating of the hand affects the operation accuracy. At the same time, the palm rest 3 adopts an adaptive adjustment design. The precise adjustment of the tilt angle of the palm rest 3 is achieved through structures such as the gear 19 and the screw 25, which can fit the user's wrist well, reduce wrist fatigue, and improve the gaming experience. The device also has a stable connection and support structure, and the first chuck 15, the second chuck 28, the first support column 29, the second support column 30 and other components ensure the stable connection and support between the hand rest 3 and the housing 1. At the same time, the housing 1 can adjust the tilt angle through multiple connecting arms and the bottom plate 35, which improves the comfort and convenience of use. The surface of the touch panel 5 adopts a frosted texture, which effectively prevents accidental sliding or misoperation when the finger slides on the touch panel 5, thereby improving the safety of use. The technical solution of the present invention can be widely applied to various keyboard scenarios that require long-term use. It can not only improve the user experience, but also effectively extend the service life of the keyboard and reduce keyboard damage and maintenance costs caused by sweaty hands.
[0036] Working principle: When the user is ready to use the keyboard, first make sure that the airbag 10 is filled with gas. The airbag 10 receives gas from the external environment through the air inlet pipe 12 and stores it inside. During use, when the user presses the key 2 on the hand rest 3, the key 2 contacts and compresses the airbag 10 through the connecting hole 11, causing the gas pressure inside the airbag 10 to increase. As the airbag 10 is compressed, the gas inside it is discharged through the air outlet pipe 13 and blows into the palm of the hand through the tiny pores on the surface of the hand rest 3. After the blowing action is completed, the airbag 10 gradually returns to its original state and prepares for the next blowing operation. When the user's wrist swings during the game, the hand rest 3 is adaptively adjusted through the connecting seat 21, the support plate 20 and the connecting shaft 22. The gear 19 on the connecting shaft 22 rotates according to the swing direction and amplitude of the wrist. This rotational action is transmitted to the screw 25 meshing therewith. The screw 25 moves along a specific trajectory during the rotation process, and at the same time drives the first support rod 17 and the second support rod 23 to rotate accordingly, thereby changing the inclination angle of the hand rest 3 to better fit the user's wrist. Through the supporting effect of the fixing ring 18, the hand rest 3 can not only be tilted in the left and right directions, but also can be swung in the front and back directions, further improving its adaptive ability.
