Description

[Technical field]

[0001] The present invention relates to the technical field of electronic accessories, and more particularly to a built-in wired keyboard cover. [Background technology]

[0002] With the progress of society, modern work is no longer limited to sitting in the office, and more flexible working styles are preferred. In addition, there are more and more situations where work must be done on the move when traveling. Compared to laptops, young people tend to use tablets more, and with the development of technology, the performance of current tablets is very high and can fully handle basic office work. In addition, in order to use tablets more conveniently, a cover with a keyboard is usually required.

[0003] Currently, there are two ways to connect a keyboard cover to a tablet: wireless and wired. Here we will explain the wired method. Looking at the published technical document "CN218675980U 'Keyboard with Magic Track Pivot Type Magnetic Levitation Cover Connected by Data Cable'", we can see that the technical solution is that the cable is exposed to the outside, which looks bad, and the wired method occupies the tablet interface, so the tablet cannot be charged during use, which affects the usage time. Summary of the Invention [Problem to be solved by the invention]

[0004] SUMMARY OF THE PRESENT EMBODIMENT The objective of the present invention is to provide a built-in wired keyboard cover to solve the problems raised in the background art mentioned above. [Means for solving the problem]

[0005] To achieve this goal, the present invention provides the following technical suggestions: The self-contained wired keyboard cover includes a keyboard component and an attached cover, both of which can be rotated relative to each other by a connecting part. The keyboard component has a built-in controller 1, which is electrically connected to the charging port, and the charging port is located on one side of the keyboard component. The mounting cover has a slot for storing the tablet, a retractable support part on the opposite side of the slot, and a controller 2 is installed inside the mounting cover, which is electrically connected to a cable. The cable is arranged on the inner edge of the mounting cover along the outside of the slot, and a notch 1 is provided on one side of the mounting cover, a connector is placed in the notch 1, and the connector is electrically connected to the cable.

[0006] The connection components include flexible printed circuit boards that are electrically connected to controller 1 and controller 2, respectively.

[0007] Furthermore, the notch 1 forms a placement slot, and a through hole is provided at the bottom of this placement slot so that the connector can pass through.

[0008] A space is provided inside the mounting cover to avoid voids, corresponding to the location of the volume buttons on the tablet, and two buttons are movably connected to the space, and the buttons extend outside the mounting cover.

[0009] One side of the mounting cover is provided with an arc-shaped notch 2, which corresponds to the power button of the tablet.

[0010] The mounting cover is provided with a groove for storing the touch pen, with several fixing convex corners provided on both sides of the groove, and parts for snapping into place at the ends of the groove.

[0011] The mounting cover has an outer diameter larger than that of the keyboard component, and a flange is provided on the outer periphery of the mounting cover to enclose and form an accommodating space that is adapted to accommodate the keyboard component.

[0012] The controller has a built-in gyro sensor. A 3.5mm audio jack is provided on one side of the keyboard component, and this audio jack is electrically connected to the controller. Effect of the Invention

[0013] This invention has less transmission delay between the keyboard component and the tablet due to the wired connection, and when charging is required, the tablet can be charged by connecting an external power source to the charging port of the keyboard component through the cooperation of controller 1, flexible printed circuit board, controller 2, cable and connector, which solves the problem of not being able to charge during use, meets the needs of users and improves the practicality of the keyboard cover. In addition, the cable is placed on the inner edge of the mounting cover along the outside of the slot, and the cable is hidden in a small space, so it is not visible from the outside and improves the aesthetics. Also, since the cable is not directly connected to the keyboard component, adjusting the rotation angle of the mounting cover and the keyboard component does not affect the guidance, and the pulling problem can be avoided. Other features and advantages of the present invention will be described in detail in the specific embodiments described below. [Brief description of the drawings]

[0015] Specific embodiment BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a semiconductor device according to an embodiment of the present invention; FIG. The keyboard cover of the present invention adopts a wired method, which reduces the delay in connection with the keyboard and is more stable. Specifically, it includes a keyboard component 1 and a mounting cover 2, both of which can be rotated by a connecting part 3. This feature does not restrict the appearance, and the usage is the same as that of the keyboard cover of the existing technology. The connecting part 3 is a flexible connecting strip, which can be bent at a large angle.

[0016] Furthermore, the keyboard component 1 has a built-in controller 12, which is electrically connected to the charging port 11. The charging port 11 is disposed on one side of the keyboard component 1. The mounting cover 2 has a slot 21, and a retractable support part 22 is disposed on the opposite side of the slot 21. The mounting cover 2 has a controller 2 23 disposed inside thereof, which is electrically connected to a cable 241. The cable 241 is connected to a connector 242, and the connection part 3 has a built-in flexible printed circuit board 4. The printed circuit board 4 is electrically connected to the controller 1 12 and the controller 2 23, respectively.

[0017] The slot 21 occupies most of the mounting cover 2, and there is a small space around the periphery of the slot 21 for mounting other components. In this embodiment, the cable 241 is arranged along the inner edge of the mounting cover 2 on the outside of the slot 21 and is hidden from view, which makes for a beautiful appearance. The cable 241 is fixed with a snap to prevent noise during use. A notch 251 is provided on one side of the mounting cover 2, which corresponds to the interface of the tablet, and a connector 242 is arranged within the notch 251.

[0018] In this embodiment, the connector 242 and the notch 251 are not connected. Most of the cable 241 is fixed and is not stretched. Therefore, the connector 242 moves only within a limited range and is not excessively stretched to spoil the appearance. When using, the connector 242 is removed from the notch 251 and the connector 242 enters the slot 21 so as not to interfere with the insertion of the tablet. Then, the tablet is inserted into the slot 21 and fixed. Specific fixing methods include providing an inner hook on the edge of the slot 21 of the mounting cover 2, or fixing by press-fitting. These can be done according to existing technology. In addition, a space avoidance design is also implemented to accommodate the power button, volume button, and speaker positions of the tablet.

[0019] Then, return the connector 242 to its original position and insert it into the interface of the tablet. Preferentially, place the outer side of the connector 242 parallel to the outer edge of the mounting cover 2, then rotate and unfold the support plate, and place the whole on the desk to support the mounting cover 2, thus completing the operation before use.

[0020] In this state, the tablet communicates with the keyboard component 1 via a wired connection, and the cable 241 is not visible from the outside, making the overall appearance simple and beautiful. In this embodiment, the keyboard component 1 can be equipped with a built-in battery, and a method of supplying power to the keyboard component 1 from the tablet can also be selected.

[0021] The connector 242 occupies the interface of the tablet, so the tablet cannot be charged. To solve this problem, an external power source is connected to the charging port 11 of the keyboard component 1, and the controller 1 12, the flexible printed circuit board 4, the controller 2 23, the cable 241, and the connector 242 cooperate to charge the tablet. In this way, the problem of not being able to charge during use is solved, the usage needs of the user are met, and the practicality of the keyboard cover is improved. If the keyboard component 1 is equipped with a built-in battery, the battery can also be charged.

[0022] Furthermore, since the cable 241 is not directly connected to the keyboard component 1, no matter how the rotation angle of the mounting cover 2 and the keyboard component 1 is adjusted, it is not affected by pulling on the cable 241, and problems caused by pulling can be avoided.

[0023] The connector 242 in this embodiment includes an external case part and a connection part, and the external case part is usually larger than the connection part. For example, when the connection part is a Type-C interface, in this embodiment, a notch 251 is arranged and a through hole 2512 is provided at the bottom, so that the connection part can pass through the through hole 2512. When a tablet is not inserted into the slot 21, the connection part and the external case part are respectively accommodated in the through hole 2512 and the left slot 2511, and the positions are fixed. This plays the role of accommodation and fixing.

[0024] In this embodiment, a clearance 261 is provided inside the mounting cover 2 to correspond to the position of the volume button of the tablet. This design prevents the side wall of the mounting cover 2 from applying pressure to the button, preventing the button from being operated incorrectly. In addition, two buttons 262 are movably connected to the clearance 261, and these buttons 262 extend outside the mounting cover 2, so that when the tablet is inserted into the slot 21, the volume can be adjusted by touching the volume button. This design provides a better operating feel than the method using a plastic film.

[0025] In addition, one side of the mounting cover 2 is provided with an arc-shaped notch 252, which corresponds to the power button of the tablet. When the tablet is inserted into the slot 21, the power button will emerge from the arc-shaped notch 252. This design provides a guiding effect, prevents injury to the hand, and improves the operating feel.

[0026] In this embodiment, the mounting cover 2 is provided with a groove 271 for storing a touch pen. The groove 271 can store up to two different types of touch pens, and the two are not stored at the same time, but one is selected. One is a thin touch pen and the other is a thick touch pen. The groove 271 is relatively long and wide, so it can accommodate both types of pens. Several fixed convex corner points 272 are provided on both sides of the groove 271, and a cut part 273 that can be fixed with a click is provided at the end of the groove 271. A thin pen is stored in the groove 271 avoiding the fixed convex corner points 272, and is fixed by the cut part 273. In the case of a thick pen, the length of the pen does not reach the cut part 273, so it is firmly fixed by the fixed convex corner point 272.

[0027] In this embodiment, the outer diameter of the mounting cover 2 is larger than that of the keyboard component 1, and a protruding edge 281 is provided on the outer periphery of the mounting cover 2, inside which a space 282 capable of accommodating the keyboard component 1 is formed. When the mounting cover 2 and the keyboard component 1 are closed, the keyboard component 1 fits into this space 282 and is protected.

[0028] Furthermore, when a user uses a tablet only by touch operation, the keyboard component 1 is usually rotated 360° and placed on the back of the tablet. In this case, when the tablet is picked up, the keyboard on the back is pressed and cannot be used normally, so in this embodiment, a gyro sensor is built into the controller 12, and when the keyboard component 1 rotates beyond a certain angle, the gyro sensor detects the change in angle, and this characteristic can be used to automatically turn off the keyboard component 1.

[0029] The cable 241 also enables data transfer between the tablet and the keyboard component 1, including audio. In this embodiment, a 3.5mm audio interface 13 is provided to meet user needs. The audio interface 13 is electrically connected to the controller 12.

[0030] The present invention is not limited to the exemplary embodiments described above, and may take different specific forms within the scope of the patent. Therefore, the embodiments are exemplary and not restrictive, and the scope of the present invention should be defined by the appended claims, and all modifications falling within the scope of the claims are intended to be included in the present invention.
