DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Please refer to Figure 1-6 ;

[0030] The keyboard leather cover of the present invention adopts a wired connection method, which reduces keyboard connection delay and is more stable. It specifically includes a keyboard assembly 1 and a mounting cover 2, which are rotated relative to each other via a connecting member 3. Based on the above features, the appearance is not limited, and the specific usage is the same as that of the keyboard leather cover in the prior art, wherein the connecting member 3 can be a flexible connecting strip that can achieve large-angle bending.

[0031] Furthermore, the keyboard assembly 1 has a built-in controller 12, which is electrically connected to a charging interface 11, which is installed on one side of the keyboard assembly 1; a slot 21 is provided in the mounting cover 2, and a retractable support 22 is provided on the side away from the slot 21, and a controller 2 23 is installed inside the mounting cover 2, which is electrically connected to a wire 241, which is connected to a connector 242, and a flexible circuit board 4 is built into the connector 3, which is electrically connected to the controller 12 and the controller 2 23 respectively.

[0032] The slot 21 only occupies most of the area of the installation cover 2. A small amount of space is provided on the periphery of the slot 21 for installing other components. In this embodiment, the wire 241 is located outside the slot 21 and distributed along the inner edge of the installation cover 2. The wire 241 is located in this small space and is covered. It cannot be directly seen from the outside, thereby hiding the wire 241 and making it more beautiful. Preferably, the wire 241 is fixed in place by a locking method to avoid abnormal noise during use. A notch 251 is provided on one side of the installation cover 2. The notch corresponds to the interface of the tablet computer, and the connector 242 is placed in the notch 251.

[0033] In this embodiment, the connector 242 is not connected to the notch 1 251. Since most of the wire 241 is fixed and cannot be stretched, the connector 242 can only swing within a limited range. This can prevent the guide from being excessively stretched and unable to be retracted, which affects the appearance. When in use, the connector 242 is moved out of the notch 1 251 to prevent the connector 242 from extending into the slot 21 and obstructing the tablet computer from being inserted. The tablet computer is then placed in the slot 21 for fixing. There are many specific fixing methods, such as providing an inner buckle near the edge of the slot 21 with the mounting cover 2, or fixing it by interference fit, which can also be referred to the existing technology. Of course, corresponding airtight designs will be provided for the power button, volume button and speaker position of the tablet computer.

[0034] After that, the connector 242 is reset and inserted into the interface of the tablet computer. Preferably, the outer side of the connector 242 is flush with the outer edge of the installation cover 2. Then, the support plate is rotated to unfold it, and the whole is placed on the desktop to support the installation cover 2 to complete the operation before use. At this time, the tablet computer communicates with the keyboard assembly 1 through a wired manner, and the wire 241 is not visible on the outside, making the overall appearance more simple and beautiful. In this embodiment, the keyboard assembly 1 can be equipped with a battery, or the tablet computer can be used to power the keyboard assembly 1.

[0035] Since the connector 242 occupies the interface of the tablet computer, it cannot be charged. In this embodiment, an external power supply can be connected to the charging interface 11 on the keyboard assembly 1. Through the mutual cooperation of controller 1 12, flexible circuit board 4, controller 2 23, wire 241 and connector 242, the tablet computer can be charged. This can solve the problem of being unable to charge during use, meet people's usage needs, and enhance the practicality of the keyboard leather case. If the keyboard assembly 1 has a built-in battery, the battery in the keyboard assembly 1 can also be charged.

[0036] In addition, the wire 241 is not directly connected to the keyboard assembly 1 , so no matter how the rotation angle of the mounting cover 2 and the keyboard assembly 1 is adjusted, it will not affect the guidance, thus avoiding pulling.

[0037] The connector 242 in this embodiment includes a shell portion and a connecting portion. Usually, the shell portion is larger than the connecting portion. For example, the connecting portion is a Type-C interface. In this embodiment, the notch 251 forms a placement position, and a through hole 2512 is provided at the bottom of the groove at the placement position for the connecting portion to pass through. When there is no tablet computer in the slot 21, the connecting portion and the shell portion are respectively placed in the through hole 2512 and the placement groove 2511 for position definition, which plays the role of storage and fixation.

[0038] In the embodiment of the present invention, a clearance position 261 is provided on the inner side of the mounting cover 2 corresponding to the position of the volume button of the tablet computer. The setting of the clearance position 261 can prevent the side wall of the mounting cover 2 from squeezing the button and making the button in the starting state. In addition, two buttons 262 are movably connected to the clearance position 261. The buttons 262 extend to the outside of the mounting cover 2. When the tablet computer is installed in the volume button slot 21, the two buttons 262 are in contact. The user can trigger the volume button through these two buttons, which has a better feel than using a plastic film.

[0039] Furthermore, a second arc-shaped notch 252 is provided on one side of the mounting cover 2. The second arc-shaped notch 252 corresponds to the power button of the tablet computer. After the tablet computer is installed in the slot 21, its power button will extend out of the second arc-shaped notch 252. The arc-shaped design can play a guiding role and avoid cutting hands, providing a better hand feel.

[0040] The mounting cover 2 of the present invention is provided with a groove 271 for placing a stylus. The difference compared with the prior art is that the groove 271 can accommodate two different styluses, but not simultaneously, but one of the two can be selected. The difference between the two styluses is that one is thinner and the other is thicker. In this embodiment, two fixing methods are provided in the groove 271. In order to meet the requirement of being able to accommodate both types of styluses, the groove 271 is relatively thick and long. A number of fixing protrusions 272 are provided on both sides of the groove 271, and a clamping portion 273 is provided at the end of the groove 271. When a thinner stylus is placed, the stylus will avoid all the fixing protrusions 272 and be placed in the groove 271, and then be fixed using the clamping portion 273. When a thicker stylus needs to be fixed, the length of the stylus does not reach the clamping portion 273, and after being placed in the groove 271, it is clamped using the fixing protrusions 272.

[0041] In the embodiment of the present invention, the outer diameter of the mounting cover 2 is larger than the outer diameter of the keyboard assembly 1, and a flange 281 is provided on the outer periphery of the mounting cover 2 to enclose a receiving space 282. The receiving space 282 is adapted to the keyboard assembly 1. When the mounting cover 2 and the keyboard assembly 1 are closed, the keyboard assembly 1 will enter the receiving space 282, thereby protecting the keyboard assembly 1.

[0042] Furthermore, when the user only needs to use the tablet computer for touch control, the keyboard assembly 1 is usually flipped 360° and placed on the back of the tablet computer. When the user picks up the tablet computer to use, the keyboard on the back will be pressed, which will affect normal use. Therefore, in this embodiment, a gyroscope is built into the controller 12. When the keyboard assembly 1 is flipped to a certain angle, the gyroscope will sense the change in angle and use this feature to close the keyboard assembly 1.

[0043] Furthermore, the wire 241 can realize data transmission between the tablet computer and the keyboard assembly 1, and audio is no exception. This embodiment adopts the method of retaining the 3.5MM audio interface 13 to meet different user needs. The audio interface 13 is electrically connected to the controller 12.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0045] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
