Description

Technical Field

[0001] The utility model relates to the field of keyboards, in particular to a small-volume keyboard with a combined arrangement. Background Art

[0002] A keyboard is a device used to input commands and data to operate computer equipment. It also refers to a set of function keys systematically arranged to operate a machine or device (such as a typewriter or computer keyboard). A keyboard is also part of a keyboard instrument and can refer to instruments that use a keyboard, such as pianos, digital pianos, or electronic keyboards. Keyboards are useful for typing practice.

[0003] The keyboard is the most commonly used and primary input device. It allows users to enter English letters, Chinese characters, numbers, punctuation marks, and other symbols into computers, thereby issuing commands and inputting data. Some keyboards also feature various shortcut keys. Over time, standalone products with various shortcut functions have gradually appeared on the market. These products come with dedicated drivers and configuration software, allowing for customized operation on compatible computers.

[0004] However, the existing numeric keypad generally has 60 keys, which include a numeric keypad, an alphabetical keypad, and a control keypad. The existing 60-key keyboard generally does not have a dedicated directional keypad. The main problems are: 1. Setting the directional key will increase the length of the keyboard, affecting its portability; 2. According to conventional thinking, the directional keys are generally set in the right area, so simply adding 4 keys affects the overall layout of the keyboard, and the keyboard coordination is poor, and it is also inconvenient to use; 3. In normal use, the length of the 60-key keyboard is relatively short, so the operation range of the right hand is relatively small, and only a single little finger can be used for operation, which affects its convenience of use. Utility Model Content

[0005] The main purpose of the utility model is to propose a small-volume keyboard with a combined arrangement, aiming to improve the existing small keyboard layout. After adding a directional keyboard, it is convenient to use without affecting the coordination of the overall layout, and is easy to operate.

[0006] To achieve the above-mentioned purpose, the present invention proposes a small-volume keyboard arranged in a modular manner, comprising a frame and 64 keys movably arranged on the frame.

[0007] The keys include a long strip editing key area consisting of 14 keys, a letter key area located below the long strip editing key area, a control key area located outside the letter area, and a direction key area located in the middle of the lower part of the frame. The direction key area is in an inverted "T" shape. The letter key area has 26 keys, and the direction key area has 4 keys.

[0008] Two spacebar keys (also known as Spacebar keys) are provided at the bottom of the control key area, and an avoidance area is formed between the two spacebars. The "up" key of the direction key area is located in the avoidance area. A protruding wedge block is provided at the bottom end of the middle part of the frame, and the lower part of the direction key area is provided on the wedge block.

[0009] In the actual design, through a reasonable layout, the small-volume keyboard has basic keys (such as numeric keys, letter keys, function keys and direction keys). By placing the direction key area in the center, the overall length of the keyboard does not change. At the same time, the space keys set at two intervals can effectively coordinate the left and right fingers to hit the keys, which is convenient for use. The layout of the wedge block and the frame makes the overall design of the keyboard have better aesthetics and design sense, which differentiates it from existing keyboards and improves its market competitiveness.

[0021] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0024] like Figures 1 to 4 As shown, a small-volume keyboard arranged in a modular manner includes a frame 2 and 64 keys movably arranged on the frame.

[0025] The keys include a long strip editing key area 11 consisting of 14 keys, a letter key area 12 located below the long strip editing key area 11, a control key area 13 located outside the letter area, and a direction key area 14 located in the middle of the lower part of the frame 2. The direction key area is in an inverted "T" shape. The letter key area 12 has 26 keys, and the direction key area has 4 keys.

[0026] Two spacebar keys 31 (also called Spacebar keys) are provided at the bottom of the control button area 13, and an avoidance area 32 is formed between the two spacebar keys 31. The "up" key 33 of the direction button area is located in the avoidance area 32. A protruding wedge block 4 is provided at the bottom end of the middle part of the frame, and the lower part of the direction button area is provided on the wedge block 4.

[0027] In the actual design, a reasonable layout is used to make the small-volume keyboard have basic keys (such as numeric keys, letter keys, function keys and direction keys). By placing the direction key area in the center, the overall length of the keyboard does not change. At the same time, the space keys 31 arranged at two intervals can effectively coordinate the left and right hand fingers to hit the keys, thereby facilitating use. The layout of the wedge block 4 and the frame makes the overall design of the keyboard have better aesthetics and design sense, which is differentiated from existing keyboards and improves market competitiveness.

[0028] Specifically, the frame is in a trapezoidal shape with a high top and a low bottom, and the keys are arranged in a stepped pattern. When the keyboard is reduced in size, the span of the fingers becomes smaller, so by increasing the height of the frame, the feeling of the fingers hanging in the air is reduced, thereby improving the convenience and comfort of use.

[0029] In an embodiment of the present invention, the keyboard is provided with six rows of keys, the number of which from top to bottom is: 14 keys, 14 keys, 13 keys, 13 keys, 7 keys and 3 keys. A reasonable layout can facilitate daily use without increasing the length of the keyboard.

[0030] Specifically, the two sides of the wedge block 4 are symmetrical inclined surfaces 41, and the two inclined surfaces 41 gradually extend from top to bottom toward the middle, which facilitates the accommodation of the direction keys while ensuring aesthetics.

[0031] In this embodiment of the present invention, the frame is provided with identically sized lighting zones 5 on both sides of the fifth row of keys. Each lighting zone 5 has three spaced-apart light-transmitting points 51. The identically sized lighting zones 5 make the keyboard more symmetrical, facilitating coordinated left-hand and right-hand use. Furthermore, the lighting zones 5 can be used to display different functions, such as uppercase and lowercase letters.

[0032] Specifically, notches 60 are provided at the two corner ends of the upper wall of the frame, and transparent light guides 6 are provided in the notches, thereby improving the overall lighting effect of the keyboard.

[0033] In the embodiment of the present invention, the light guide 6 is arranged in a curved shape, and the lower wall of the light guide 6 is a concave and convex prismatic block 61. The light guide 6 can be snap-fitted or adhesively bonded, making it easy to install. The prismatic block (similar to a diamond pattern) can ensure light scattering while preventing glare, effectively improving the keyboard's aesthetics and differentiating it from existing keyboards.

[0034] Specifically, a PCB board is provided in the frame, and the PCB board (not shown) is provided with a light-emitting body (not shown), and the light-emitting body is an LED lamp. The button is made of transparent or translucent material, thereby ensuring a predetermined lighting effect. At the same time, the light-emitting body can also be set at the position of the light guide 6, thereby realizing the lighting effect of the light guide.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the practical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
