Description
Technical Field
[0001] The utility model relates to the technical field of keyboards, in particular to a split type wireless ergonomic keyboard. Background Art
[0002] The keyboard is currently the most common way to input text. As the current mainstream human-computer interaction device, physical keyboards have a huge ownership and sales volume in the market. However, except for conventional keyboards, it is difficult to find well-designed ergonomic keyboards on the market.
[0003] The lifting of the hand is the vertical posture. Most ordinary standard keyboards are not designed with a vertical lifting angle, but the keyboard itself is often thick, and most standard ordinary keyboards do not have a keyboard wrist rest, which causes the hand to be actively lifted for a long time when typing. Controlling the lifting of the wrist requires continuous force from the upper forearm muscles, which often causes forearm soreness. What's worse, due to the vertical lifting angle being too high, the wrist is suspended in the air for a long time, the wrist cannot be supported, and eventually the wrist becomes fatigued, the typing speed is reduced, and in severe cases, diseases such as arthritis may even occur.
[0004] For some keyboards equipped with wrist rests, the problem of vertical lifting angle is indeed improved to a certain extent, but the position of the wrist rest often cannot fit the wrist well. Due to individual differences and different hand sizes of typists, a single-size wrist rest is often difficult to meet the needs of everyone. In extreme cases, it may lead to the occurrence of cumulative diseases such as carpal tunnel syndrome.
[0005] Carpal tunnel syndrome is a type of discomfort caused by damage to the central nerve in the wrist. Excessive flexion or extension of the wrist causes inflammation and swelling of the sheath in the carpal tunnel, which compresses the median nerve and injures the median nerve. It is characterized by the excitement or loss of local nerve function in the fingers, causing numbness, tingling, no gripping sensation, and muscle atrophy and loss of flexibility. Its incidence rate in women is 3-10 times that of men. Therefore, the keyboard must be designed appropriately to avoid a non-straight wrist state. Therefore, it is necessary to reduce the longitudinal lifting angle of the keyboard to keep the arm and wrist in a nearly straight line.
[0006] As a human-computer interaction device that is in direct contact with the operator, it is extremely important to design a keyboard with excellent ergonomic design. Excellent ergonomic design can not only improve input efficiency and reduce operator fatigue, but also avoid injuries to the user's body such as carpal tunnel syndrome, tenosynovitis and other cumulative injury-related diseases. It is also very helpful in increasing product sales. To this end, the present application proposes a split wireless ergonomic keyboard. Utility Model Content

[0040] The split wireless ergonomic keyboard provided by the utility model solves the problem of poor ergonomic design that is common in keyboards on the market to a certain extent through the coordinated design of multiple structures. The keyboard design not only makes the typing process more comfortable and reduces fatigue and human body load, but also adopts the concept of a split keyboard. The keyboard design scheme can continue to be developed and has great expansion potential.
[0041] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0042] Embodiment 1:
[0043] Please refer to Figure 1 - Figure 4 , a split type wireless ergonomic keyboard, comprising:
[0044] The keyboard body 1 and the keyboard body 2 are symmetrically arranged, the upper end surfaces of the keyboard body 1 and the keyboard body 2 are inclined, and a button part 3 is arranged above the keyboard body 1 and the keyboard body 2. The button parts 3 on the keyboard body 1 and the keyboard body 2 are inclined at their ends close to each other.
[0045] The overall keyboard adopts a split structure, and the overall layout of the keyboard is also considered from the perspectives of the left hand and the right hand; the split keyboard can well solve a series of problems caused by the close distance between the two hands brought by the conventional keyboard, so this application adopts a split design, dividing the keyboard into two parts: keyboard body 1 and keyboard body 2. Such a design can not only make the left and right hands work at the same level, but also help to develop correct typing habits. The overall keyboard adopts a split design, dividing the keyboard into two operating parts for the left and right hands, and a Bluetooth module is used for information transmission between the two keyboards.
[0046] The optimal wrist tilt angle is between 0°-5°. Exceeding this angle will cause the forearm muscles to be in an over-stretched state, which will lead to poor blood supply for a long time, which is the main cause of muscle soreness. Therefore, in this application, the upper end surfaces of the keyboard body 1 and the keyboard body 2 2 are longitudinally inclined with an inclination angle of 5°, and the end of the keyboard body 1 and the keyboard body 2 2 close to the palm is the low end.
[0047] A magnetic support seat 4 is provided at the upper end of the keyboard body 1 and the side away from each other, and a side lifting plate 5 is provided at the lower end of the keyboard body 1 and the side away from each other. Specifically, the lateral tilt angle of the keyboard is directly related to the bones and muscles of the forearm. The appropriate lateral tilt angle has a direct impact on reducing the tension of the forearm muscles. When both hands are placed on the table in a relaxed state, the angle is between 20°-45°. Therefore, in the present application, when the side lifting plate 5 is unfolded, the lateral lifting angle of the keyboard body 1 and the keyboard body 2 2 is set to 0°-40°. Furthermore, in order to meet different usage habits, when the side lifting plate 5 is unfolded, the lifting angle of the keyboard body 1 and the keyboard body 2 2 is set to five gears, and the five gears are 0°, 10°, 20°, 30°, and 40° respectively.
[0048] As for the storage of the keyboard, since the keyboard is of a unique split structure, you only need to fold up the side lifting plate 5 and fit the keyboard body 1 and the keyboard body 2 2 together front and back. The magnetic support seat 4 located on one side of the keyboard body 1 and the keyboard body 2 2 has a magnetic design and can automatically align and fit the keyboard body 1 and the keyboard body 2 2 and play an effective supporting role to prevent accidental touches caused by squeezing each other inside the keyboard.
[0049] After investigation, it was found that few users are willing to spend more time to adapt to the new keyboard. At the same time, according to the concept of ergonomics, machine design should be people-oriented, so that the keyboard can adapt to human hands. Therefore, the overall layout of the keyboard of this application has not been changed significantly, the order of commonly used keys has not changed, and small adjustments have been made to special keys, only changing the specific position of the keys on the keyboard.
[0050] Overall, the keyboard adopts a surround layout, with the keys arranged around the fingers and based on the different lengths of the fingers and the inclination angle of the keyboard. In this arrangement mode, the commonly used keys are close to the trigger distance of each finger, shortening the overall cumulative typing distance.
[0051] Embodiment 2:
[0052] The split wireless ergonomic keyboard provided in Example 1 is further optimized, specifically, as follows: Figure 5 As shown, the key part 3 on the keyboard body 1 is divided into a reserved key, a modification key, and an additional key; the modification key is located above the reserved key, and the additional key is located on one side of the reserved key and the modification key.
[0053] The reserved keys are:
[0054] Numeric keys, letter keys, ESC key, · key, TAB key, CAPS LOCK key, SH I FT key, fn key, control key, opt i on key, command key, space key;
[0055] Modifier keys include:
[0056] Brightness down key, brightness up key, previous key, play / pause key, next key, task manager key;
[0057] Additional keys include:
[0058] Customize key 1, customize key 2, customize key 3, customize key 4, customize key 5, customize key 6.
[0059] It can be seen that, since the basic numeric and letter keys need to be retained for regular input, the numeric keypad, edit keys, function keys and F keys on the full-size keyboard are deleted, six custom keys are added on the left side according to the size of the keyboard, and the top-level shortcut keys are set at a farther distance from the top hand;
[0060] The left-hand key area includes an auxiliary area and a main area. The auxiliary area mainly includes custom 1 to custom 6 keys, which are mainly used for user-defined programming. They are designed to solve common key combination situations and define complex combinations such as Ctrl+C and Ctrl+V to one key, thereby improving key efficiency and reducing false touch rates. The main area includes numeric keys, letter keys, auxiliary keys, and shortcut keys.
[0061] The main design idea is to eliminate the sense of disconnection between the use of keyboard and mouse. The 6 custom buttons in the left-hand area allow users to customize them to replace commonly used mouse operations, such as switching software, switching tabs, opening commonly used software, etc., so that most operations can be completed on the keyboard. Reducing the number of times your hands leave the keyboard is the best choice.
[0062] Embodiment 3:
[0063] The split wireless ergonomic keyboard provided in Example 1 is further optimized, specifically, as follows: Figure 6 As shown, the key part 3 on the keyboard body 2 is divided into a reserved key, a modification key, and an additional key; the modification key is located above the reserved key.
[0064] The reserved keys are:
[0065] Numeric keys, letter keys, minus key, equal sign key, DELETE key, left bracket key, right bracket key, comma key, semicolon key, quotation mark key, ENTER key, comma key, period key, slash key, SHIFT key, command key, space key;
[0066] Reserved keys also include:
[0067] ↑ key, ↓ key, ← key, → key;
[0068] Modifier keys include:
[0069] Search, Do Not Disturb, Volume Down, Volume Up, Mute.
[0070] It can be seen that since regular input requires retaining basic numeric keys and letter keys, the numeric keypad, editing keys, function keys and F keys on the full-size keyboard are deleted, and the top-level shortcut keys are set at a farther distance from the top hand according to the size of the keyboard.
[0071] The right-hand keypad includes numeric keys, letter keys, arrow keys, modifier keys, crossover keys, and security keys.
[0072] Overall, this key takes into account all daily input requirements, and there are corresponding keys for special needs.
[0073] Embodiment 4:
[0074] The split wireless ergonomic keyboard provided in Example 1 is further optimized, specifically, as follows: Figure 6 As shown, a fingerprint recognition button is provided at the upper end of the keyboard body 2 and at the upper right corner of the key portion 3. The fingerprint recognition button is provided at the upper right corner of the keyboard to facilitate unlocking and starting the computer.
[0075] Embodiment 5:
[0076] The split wireless ergonomic keyboard provided in Example 1 is further optimized, specifically, as follows: Figure 2 As shown, a charging port 6 is provided on one side of the keyboard body 1 and the keyboard body 2 2 ; and a wireless charging coil is provided inside the keyboard body 1 and the keyboard body 2 2 .
[0077] The keyboard has two charging modes: wired charging and wireless charging.
[0078] When a faster charging speed is needed, a cable can be used to connect the charging port 6 on the side of the keyboard. The left and right keyboards have separate charging ports 6 for fast charging.
[0079] When used with the matching mouse pad, the mouse pad has a built-in wireless charging coil that matches the wireless charging coil on the back of the keyboard for wireless charging, eliminating the complicated charging steps and allowing seamless charging while typing to maintain adequate battery life.
[0080] Embodiment 6:
[0081] The split wireless ergonomic keyboard provided in Example 1 is further optimized, specifically, as follows: Figure 4 As shown, an external port is arranged on the outer side of the keyboard body 1.
[0082] The side of the keyboard supports the connection of accessory components, such as USB-A, USB-C and Apple Magsafe mobile phone holder. In this way, the keyboard can adopt modular design as much as possible while ensuring the original function, giving the keyboard huge expansion space and potential.
