Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A foldable keyboard, refer to fig. 1 to 4, the unfolded state in normal use is as shown in fig. 1, a flexible material shell 1 and a keyboard main body 3 are fixed by pressing; when the folding is started, the folding state in which the keyboard main body 3 is folded in two up and down (i.e., in two in the horizontal direction) along the folding mechanism 2 is shown in fig. 2; on the basis of fig. 2, the folded state after folding left and right (i.e. folding in half in the vertical direction) is continued along the gap 6 with a predetermined width left between the keyboard regions which are symmetrical left and right is shown in fig. 3. Because the keyboard main body is wrapped by the flexible material shell, after the keyboard main body is folded twice in the horizontal direction and the vertical direction, the size of the folded keyboard main body is one fourth of the size of the folded keyboard main body when the keyboard main body is unfolded. Meanwhile, due to the light and thin characteristic of the flexible material shell, the whole keyboard is lighter in weight. The keyboard main body is internally embedded with a wireless data connection module 4, the wireless data connection module is used for being connected with computer equipment, wherein the wireless data connection module can be a Bluetooth module, and the computer equipment comprises but is not limited to a PC (personal computer), a tablet computer or a smart phone and the like. The foldable keyboard is connected with the computer equipment through the wireless data connection module, a data line does not need to be configured for the keyboard, the use of a user is facilitated, and the foldable keyboard is simpler.

It can be understood that the folding mechanism can also be used for connecting keyboard regions which are symmetrical left and right, a gap with a preset width can be left between the keyboard regions which are symmetrical up and down, when folding, the folding mechanism is firstly folded left and right along the folding mechanism, and then the folding mechanism is folded up and down along the gap with the preset width, and the folding effect is consistent with the above embodiments.

Further, in one embodiment, as shown in fig. 4, the folding mechanism 2 is a damping spindle 21. Damping refers to the characteristic of any vibration system in vibration that the amplitude of vibration gradually decreases due to external action or the inherent cause of the system, and the quantitative representation of the characteristic. The damping shaft is a device for quickly damping vibration generated after impact and increasing damping.

When the keyboard is unfolded to normally work, the damping rotating shaft can form rigid support for the keyboard main body; when the keyboard main body is folded, the damping rotating shaft can be quickly closed when the speed or the acceleration exceeds an opening and closing threshold value, so that the keyboard regions which are symmetrical up and down of the keyboard main body can be folded crudely and are not easy to loosen. The damping pivot can keep normal resistance between 0 degree and 360 degrees, and life reaches no decay more than 3 ten thousand times, the stable performance, simultaneously, damping pivot simple structure, convenient assembling, the low noise wearability is good, is fit for the folding mechanism as the keyboard.

Further, in one embodiment, as shown in fig. 4, the flexible material housing 1 is made of microfiber leather 11 material. Microfiber leather, namely microfiber-reinforced PU leather, has the characteristics of extremely excellent wear resistance, excellent bending resistance, strong flexibility, air permeability and aging resistance. Because the gap 6 with the preset width is arranged between the keyboard areas which are symmetrical left and right in the keyboard main body, and the microfiber leather wraps the keyboard main body, the keyboard main body is favorably and frequently folded by utilizing the characteristics of bending resistance, wear resistance, strong flexibility and aging resistance of the microfiber leather without influencing the folding effect and the service life; the gap of the preset width may be set according to the thickness of the keyboard body, for example, the preset width may be set to be 4 times of the thickness of the keyboard body.

Further, in one embodiment, the keyboard layout of the keyboard body is a standard full-size keyboard layout. A standard full-size keyboard refers to a keyboard with a key pitch within 19mm-19.5 mm. The key pitch refers to the distance between keys in the main working area of the keyboard, and is approximately equal to the length of one keycap plus the length of one gap. Since the keyboard can be folded twice in the horizontal and vertical directions, the size of the keyboard after being completely folded is small enough, so that the keyboard layout can use a standard full-size keyboard. The standard full-size keyboard layout is beneficial to improving the typing comfort level, and brings better typing experience compared with a non-standard size keyboard.

Further, in an embodiment, as shown in fig. 4, the keyboard main body includes a keyboard upper cover 31, a keyboard lower cover 32, a key flexible circuit board 33, and a key cap 34; the keycaps are positioned on the key flexible circuit board and correspond to the keys on the key flexible circuit board one by one; the key flexible circuit board is arranged between the keyboard upper cover and the keyboard lower cover, and the keyboard upper cover and the keyboard lower cover are fixed through AB glue. The key flexible circuit board is a flexible Printed circuit board which is made of polyimide or polyester film as a base material, has high reliability and flexibility, has the characteristics of high wiring density, light weight, thin thickness and good bending property, and is beneficial to reducing the whole weight of the keyboard and convenient to fold; the AB glue is a different name of two-liquid mixed hardening glue, has high bonding strength, and can bond the keyboard upper cover and the keyboard lower cover through a glue dispensing process.

Further, in an embodiment, as shown in fig. 4, the keyboard main body further includes a flexible circuit board reinforcing plate, and the flexible circuit board reinforcing plate is padded below the key flexible circuit board. Because the key flexible circuit board has the characteristics of light weight and easy breaking, the flexible circuit board reinforcing plate is fixed below the key flexible circuit board, and the key flexible circuit board can be reinforced and reinforced. Preferably, the flexible circuit board reinforcing plate is a glass fiber plate, and the glass fiber plate has the characteristics of sound absorption, sound insulation, heat insulation, environmental protection, flame retardance and the like.

Further, in one embodiment, as shown in fig. 4, the wireless data connection module 4 comprises a bluetooth module printed circuit board 41 and a polymer lithium battery 42, i.e. the keyboard is connected with the computer device via bluetooth. Specifically, the bluetooth module printed circuit board, i.e., the pcb (printed circuit board) may be configured with a bluetooth module, and the polymer lithium battery 42 is used to supply power to the bluetooth module.

Further, in an embodiment, as shown in fig. 1 and 4, the keyboard main body further includes a touch panel module 5, the touch panel module includes a touch panel 51, touch panel keys 52, and a touch panel main plate 53, the touch panel 51 and the touch panel keys 52 are disposed on the touch panel main plate 53, and a mylar sheet is attached to a surface of the touch panel 51. Wherein, Mylar film is a film formed by ester exchange, vacuum polycondensation and biaxial stretching, has the characteristics of stable size, flatness, tear strength, heat and cold resistance, moisture and water resistance, chemical corrosion resistance and the like, and ensures that the touch pad is durable. The touch panel module 5 can be disposed in a lower right keyboard region of the keyboard body according to usage habits for realizing the function of the mouse.
