The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1-3, an electronic device 100 according to an embodiment of the invention includes: a body 10, a screen 20, and a jacking assembly 30. The body 10 is a hollow frame structure, and the screen 20 is mounted on one side of the body 10 to facilitate human-computer interaction through the screen 20. The screen 20 and the main body 10 enclose a receiving cavity 11. The jacking assembly 30 includes a lead screw 31 and a jacking member 32. The screw 31 is rotatably mounted on the body 10 and is in driving fit with the jack-up member 32, and the jack-up member 32 is received in the receiving cavity 411 and moves in a direction perpendicular to the screen 20 under the driving action of the screw 31 to jack up a part of the screen 20 and form at least one protrusion 21 on the outer surface of the screen 20. In this embodiment, at least one protrusion 21 can simulate a physical key to input information, because the middle protrusion of each physical key and a gap is formed between two adjacent physical keys. Therefore, the user can find the corresponding key by touching the touch without looking at the screen 20, thereby inputting information to the electronic device 100, i.e. a so-called "touch typing" input mode.

In the present embodiment, the screen 20 is a flexible touch screen, which is an inductive liquid crystal display device capable of receiving input signals such as contacts, when a graphical button on the screen is touched, the tactile feedback system on the screen can drive various connecting devices according to a pre-programmed program to replace a mechanical button panel, and an audio/video effect is produced by the liquid crystal display screen; meanwhile, the flexible touch screen can be stretched and bent under stress, so that the screen 20 can be changed into a shape suitable for different requirements.

It is understood that the electronic device 100 further includes a battery, a microprocessor (CPU), and a circuit board (not shown) received in the receiving cavity 11. The battery is used for providing power for the electronic equipment; the microprocessor is used for interpreting and processing data in the software of the electronic device 100 and executing corresponding control instructions; the circuit board is used as a support body of electronic components of the electronic equipment and is used as a carrier for electrical connection among the electronic components.

The screen 20 comprises a touch detection component and a touch screen controller, wherein the touch detection component is positioned in front of the screen 20 and is used for detecting the touch position of a user and receiving and sending the touch position to the touch screen controller; the touch screen controller receives touch information from the touch point detecting device, converts the touch information into touch point coordinates, sends the touch point coordinates to the microprocessor, and receives and executes commands sent by the microprocessor. Preferably, the screen 20 is a capacitive screen, the surface of the capacitive screen is coated with a transparent conductive layer ITO, the voltage is connected to four corners, the small direct current is distributed on the surface of the screen to form a uniform electric field, when a user touches the screen with a finger, the human body is used as one pole of the coupling capacitor, the current is collected from the four corners of the screen to form the other pole of the coupling capacitor, and the touch screen controller calculates the relative distance from the current to the touch position to obtain the touch coordinate.

In the present embodiment, the lifting member 32 includes a mounting plate 321 and at least one head 322. The mounting plate 321 is substantially rectangular plate-shaped and is adapted to the shape and size of the screen 20; at least one head 322 is mounted on the side of the mounting plate 321 facing the screen 20. The mounting plate 321 is provided with a screw hole 323 corresponding to the screw rod 31. One end of the screw rod 31 is received in the receiving cavity 11 and screwed into the screw hole 323 of the mounting plate 321, and the other end is rotatably mounted on the bottom wall of the receiving cavity 11. One end of the screw 31, which is far away from the mounting plate 321, extends out of the receiving cavity 11 and forms a handle 311 on the outer side, so that a user can rotate the screw 31 through the handle 311.

In this embodiment, a bearing 12 is installed at a position of the body 10 corresponding to the lead screw 31, an outer ring of the bearing 12 is fixedly connected with the body 10, and an inner ring of the bearing 12 is sleeved on the lead screw 31 and is fixedly connected with the lead screw 31. The friction between the screw 31 and the body 10 can be effectively reduced by adding a bearing 12 on the body 10.

When the electronic device 100 is switched to the input mode, the input interface a appears on a part of the screen 20. In this embodiment, a squared figure input interface a is taken as an example, and the squared figure input interface a is generally used in electronic devices such as mobile phones and PADs, and is formed by putting 26 letter packets into a 3 × 3 key grid, thereby forming an input interface a suitable for ergonomics. Correspondingly, the number of the plugs 322 is nine, and the nine plugs 322 are respectively located below the screen 20, and the arrangement of the nine plugs 322 on the mounting plate 321 corresponds to the arrangement of the nine key grids in the nine-grid input interface a. In the present embodiment, the height H1 of each plug 322 is 1 mm-15 mm, preferably 3 mm-8 mm, but not limited thereto.

When the user does not need to input information, or the user does not need to move out of the screen 20 to input information, the screen 20 of the electronic device 100 is a smooth screen with a flat surface like a common screen, and the nine headers 322 on the jacking pieces 32 are respectively positioned below the screen 20 and do not apply pressure to the screen 20.

When a user needs to move out of the screen 20 for inputting information, i.e. needs to switch to the "touch typing" mode, the screw 31 drives the jacking member 32 to move in a direction perpendicular to the screen 20, so as to lift nine jacks 322 on the jacking member 32 and abut against the lower surface of the screen 20; the screw 31 further drives the nine jacks 322 of the jack 32 to rise, and the nine key areas in the nine-grid input interface a of the flexible screen 20 are respectively subjected to upward supporting forces of the corresponding jacks 322, so that the nine key areas are deformed and protrude out of other areas of the screen 20, thereby forming nine protruding portions 21 simulating physical keys.

It is understood that the number of the convex portions 21 in the above-described embodiment is not limited to nine, and the arrangement is not limited to the nine-key-grid arrangement in the nine-square input interface a. Different numbers and different arrangements of the plugs 322 can be set according to actual needs. In some embodiments, the number and arrangement of the protruding portions 21 may be set according to the size of the screen 20 of the electronic device 100. For example, a screen 20 of less than 6 inches is more suitable for the input rules of the squared figure. Preferably, the number of protrusions 21 required for the input rule using the grid is 9-20, preferably 16. Because, in this case, the size of the screen 20 is small, the tension of the screen 20 determines that it is not appropriate to use the denser key protrusions; meanwhile, if too many protrusions 21 are formed on the small-sized screen 20, an uneven feeling of distinction is not easily generated between every two adjacent protrusions 21, and thus the user cannot input information quickly in the "touch typing" mode. For the screen 20 with more than 6 inches, the input rule of the squared figure and the input rule of the 26 letters can be simultaneously applied; in particular, more than 8 inches of screen 20 is more suitable for 26 letter input rules. Preferably, the number of bosses 21 required for the 26-letter input rule is 26-35.

In the present embodiment, the key region formed by the plurality of protrusions 21 is located on the lower side of the screen 20 of the electronic device 100 (i.e. the side of the screen 20 close to the user when the user normally uses the electronic device 100), and its area occupies 1/4-2/3 of the area of the screen 20. It can be understood that the ratio of the area of the key region formed by the plurality of protrusions 21 on the screen 20 is not too small or too large, and when it is too small, it is difficult to form a good concave-convex feeling between the plurality of protrusions 21; if the finger is too large, the finger operation range of the user can be exceeded, the efficiency of inputting information by the user is reduced, and the single-hand operation is not easy.

The jacking assembly 30 further comprises a guide for guiding the movement of the mounting plate 321. In this embodiment, the guiding element is a guiding post 33, the guiding post 33 is fixedly disposed in the receiving cavity 11 of the body 10, the mounting plate 321 is provided with a guiding hole 324 corresponding to the guiding post 33, the guiding post 33 slidably penetrates through the guiding hole 324, and the mounting plate 321 moves under the guiding cooperation effect of the guiding post 33 and the guiding hole 324. Preferably, the number of the guide posts 33 and the number of the guide holes 324 are two, and may be one or more than two.

It will be appreciated that the lead screw 31 is arranged parallel to the guide post 33. When the screw 31 and the guide post 33 are disposed perpendicular to the screen 20, and accordingly, the screw hole 323 and the guide hole 324 are straight holes, the mounting plate 321 performs vertical lifting movement under the screwing action of the screw 31 and the screw hole 323 and the guiding cooperation action of the guide post 33 and the guide hole 324; when the screw 31 and the guide post 33 can be disposed obliquely to the screen 20, the screw hole 323 and the guide hole 324 are correspondingly inclined holes, and the mounting plate 321 performs an inclined lifting motion under the screwing action of the screw 31 and the screw hole 323 and the guiding cooperation action of the guide post 33 and the guide hole 324.

It will be appreciated that the guide post 33 may be circular in cross-section, and accordingly, the guide hole 324 is a circular hole; the guide post 33 may also be square in cross-section, and accordingly, the guide hole 324 should also be a square hole, so as to further prevent the mounting plate 321 from rotating; but is not limited thereto as long as the sectional shape of the guide post 33 is maintained to match the shape of the guide hole 324 and the sliding of the guide mounting plate 321 is facilitated.

In this embodiment, a limiting portion 331 is protruded from one end of the lead screw 31 and/or the guide post 33 close to the screen 20 along the radial direction, and the limiting portion 331 is substantially in a ring structure. The outer diameter of the limiting portion 331 is larger than the diameter of the screw hole 323 and/or the guide hole 324, so as to limit the mounting plate 321 from moving in the direction of the screen 20, and further prevent the top 322 from pressing the screen 20 excessively. Preferably, the distance S between the position-limiting portion 331 and the screen 20 is smaller than the height H1 of the head 322, and the difference between the height H1 of the head 322 and the distance S between the screen 20 is the height H2 of the protrusion 21, in this embodiment, the height H2 of the protrusion 21 ranges from 1mm to 10mm, preferably from 3mm to 8mm, but is not limited thereto.

Referring to fig. 4, according to an electronic apparatus of another embodiment of the invention, the jacking assembly 30 further includes a driving unit 34, and the driving unit 34 is fixedly disposed on an inner sidewall of the receiving cavity 11 and connected to the screw 31. The driving unit 34 is electrically connected to the microprocessor of the electronic device 100, and when the microprocessor of the electronic device 100 receives an instruction from a user and needs to switch the input mode to the "touch mode", the driving unit 34 is actuated to drive the screw 31 to rotate, thereby achieving the effect of automatically switching the input mode. Preferably, the driving unit 34 is a servo motor and can perform a forward and reverse rotation motion, but is not limited thereto.

It is understood that a function key such as "bump" may be further disposed on the input interface a of the screen 20 or the body 10, and the function key is electrically connected to the microcontroller for activating the driving unit 34. In practical applications, when the user needs to switch the "touch typing" input mode, the "convex" key is pressed to feed back the request information of the user to a microcontroller in the electronic device 100, and then the microcontroller controls the driving unit 34 to drive the lead screw 31 to rotate, so as to drive the jacking piece 32 to jack up a part of the screen 20 and form the convex portion 21 on the outer surface of the screen 20. The convex part 21 enables the surface of the screen 20 to have concave-convex touch, and the user identifies the input area where the finger is located according to the concave-convex touch, so that the user does not need to look at the key area all the time, the accurate input of information can be realized, and the input efficiency is effectively improved.

The electronic device 100 jacks up a part of the screen 20 through the jack-up component 30, and forms the convex part 21 on the outer surface of the screen 20, and the convex part 21 corresponds to the key grid in the input interface a of the screen 20, so as to simulate a physical key to input information. Because the middle of each solid key protrudes and a gap is formed between every two adjacent solid keys. Therefore, the user can find the corresponding key by touching the touch without looking at the screen 20, so that the input efficiency of the user is obviously improved, and the use experience of the user is effectively improved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
