Description

Technical Field

[0001] This utility model relates to the field of tablet computer accessories, specifically a tablet case with a keyboard and a capacitive pen. Background Technology

[0002] Currently, most tablet cases on the market suffer from limited functionality. On one hand, most tablet cases merely function as a protective shell, lacking the crucial feature of a keyboard. In daily office work and study scenarios, people often have a need for extensive text input. Relying solely on the tablet's built-in virtual keyboard results in low input efficiency and a poor tactile experience. Existing tablet cases do not provide a physical keyboard for use with tablets, significantly limiting their efficient application in word processing and other areas, causing considerable inconvenience to users.

[0003] On the other hand, while capacitive pens are indispensable tools for tablet drawing and handwriting annotation, few tablet cases are designed with dedicated storage and support functions for them. Most common tablet cases on the market lack a suitable place to store the capacitive pen, forcing users to store it separately. This not only increases the risk of losing the pen but also prevents it from being easily accessible when needed, disrupting the continuity of use. Furthermore, there are virtually no designs to charge the pen or facilitate its integration with the tablet, limiting its use to issues such as battery life and compatibility, thus hindering its ability to fully utilize its auxiliary function in tablet use.

[0004] Therefore, tablet cases that lack keyboards and capacitive pen compatibility are unable to meet the needs of people in diverse tablet usage scenarios and can no longer adapt to the current requirements for integrated and multifunctional tablet accessories.

[0005] Therefore, there is an urgent need for a tablet case that can compensate for these functional deficiencies, has a keyboard, and complete capacitive pen functions to solve these problems. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of existing tablet cases that are limited in function and lack comprehensive functions related to keyboard and capacitive pen compatibility, and to provide a tablet case with a keyboard and capacitive pen.

[0007] Within this tablet case, the various components work together to form a complete and practical circuit connection. When the tablet is placed inside the case, the tablet connector passes through the edge of the case and electrically connects to the tablet. Simultaneously, this connector connects to a circuit board embedded within the case, which in turn connects to the keyboard. This creates a circuit channel between the tablet and the keyboard, allowing users to perform text input and other operations on the tablet via the keyboard. This significantly improves input efficiency and user experience, meeting the needs of daily office work, study, and other scenarios.

[0008] Furthermore, since the keyboard and the charging pen sleeve on the flexible connecting skin are also electrically connected, while the tablet powers the keyboard through the tablet plug and circuit board, the electrical energy received by the keyboard can also be further conducted along the circuit to the charging pen sleeve. The charging pen sleeve contains a capacitive pen, and after the electrical energy is transferred to the charging pen sleeve, it can wirelessly charge the capacitive pen inside the sleeve, ensuring that the capacitive pen always has sufficient power. This allows users to easily take out the capacitive pen at any time and perform operations such as drawing and handwriting annotations on the tablet, making the whole process seamless and convenient.

[0009] This design integrates multiple functions into one tablet case, effectively compensating for the functional deficiencies of existing tablet cases, meeting the diverse needs of people using tablets in different scenarios, and conforming to the current requirements of integrated and multifunctional tablet accessories, bringing users a better user experience.

[0010] This application provides a tablet case with a keyboard and a capacitive pen, comprising:

[0011] The tablet case and keyboard are provided. The tablet case is provided with a flexible connecting skin that is fixedly connected to the outer shell of the keyboard. The flexible connecting skin is provided with a charging pen sleeve that is electrically connected to the keyboard. The charging pen sleeve contains a capacitive pen.

[0012] The tablet plug extends through the edge of the tablet cover into the cavity where the tablet is placed.

[0015] Furthermore, a second ribbon cable board is also provided on the circuit board, and a second ribbon cable board socket is provided on the keyboard. The second ribbon cable board extends into the inside of the keyboard housing and is plugged into the second ribbon cable board socket.

[0016] Furthermore, the keyboard also contains embedded wires, and the charging pen sleeve contains embedded electromagnetic coils for charging the capacitive pen. One end of the wires is electrically connected to the keyboard, and the other end is electrically connected to the electromagnetic coils.

[0017] Furthermore, the charging pen sleeve also contains a magnetic block that magnetically connects with the capacitive pen.

[0018] Furthermore, the charging pen sleeve is equipped with a spring-loaded component, which includes a cooperating spring and a hook. The hook slides inside the charging pen sleeve under the action of the spring to lock the capacitive pen and pop it out when pressed.

[0019] Furthermore, the tablet case also has magnetic strips on the edges that magnetically attach to the capacitive pen.

[0020] Furthermore, a plate support plate is hinged to the back of the plate cover.

[0021] Furthermore, finger slots are also provided on the back of the tablet case.

[0022] Furthermore, the tablet case also has a camera hole.

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0045] According to one embodiment of the present invention, such as Figures 1-8 As shown, a tablet case with a keyboard and a capacitive stylus includes:

[0046] The tablet cover 1 and the keyboard 2 are provided. The tablet cover 1 is provided with a flexible connecting skin 3 that is fixedly connected to the outer shell of the keyboard 2. The flexible connecting skin 3 is provided with a charging pen cover 4 that is electrically connected to the keyboard 2. The charging pen cover 4 is provided with a capacitive pen 5.

[0047] The tablet plug 6 extends through the wrapping edge of the tablet sleeve 1 into the cavity where the tablet computer is placed.

[0048] Circuit board 7 is embedded in the flat panel sleeve 1 and is electrically connected to the flat panel plug 6 and the keyboard 2.

[0049] In this embodiment, the various components in the tablet case 1 work together to form a complete and practical circuit connection link. When the tablet is placed inside the tablet case 1, the tablet plug 6 passes through the edge of the tablet case 1 and is electrically connected to the tablet. At the same time, the tablet plug 6 is connected to the circuit board 7 embedded in the tablet case 1, and the circuit board 7 is electrically connected to the keyboard 2. In this way, a circuit connection channel is built between the tablet and the keyboard 2, which allows the user to perform text input and other operations on the tablet through the keyboard 2, greatly improving input efficiency and operation feel, and meeting the usage needs of daily office, study and other scenarios.

[0050] Furthermore, since the keyboard 2 and the charging pen sleeve 4 on the flexible connecting skin 3 are also electrically connected, when the tablet computer supplies power to the keyboard 2 through the tablet plug 6 and the circuit board 7, the electrical energy obtained by the keyboard 2 can also be further conducted along the circuit to the charging pen sleeve 4. The charging pen sleeve 4 contains the capacitive pen 5. After the electrical energy is transferred to the charging pen sleeve 4, it can wirelessly charge the capacitive pen 5 inside the sleeve, ensuring that the capacitive pen 5 always has sufficient power. This allows users to easily take out the capacitive pen 5 at any time and perform operations such as drawing and handwriting annotations on the tablet computer. The whole process is seamless and convenient.

[0051] Through this design, Tablet Case 1 integrates multiple functions, effectively making up for the functional deficiencies of the existing Tablet Case 1, meeting the diverse needs of people using tablets in different scenarios, conforming to the current requirements of integrated and multifunctional tablet accessories, and bringing users a better user experience.

[0052] In one possible implementation, such as Figure 4 and Figure 6 As shown, the flat plug 6 is provided with a first ribbon cable board 8, and the circuit board 7 is provided with a first ribbon cable board socket 9. The first ribbon cable board 8 extends into the flat sleeve 1 and is plugged into the first ribbon cable board socket 9.

[0053] When this embodiment is implemented, as follows: Figure 4 and Figure 6 As shown, a slider 10 is provided on the flat plug 6, and the first ribbon cable board 8 is fixed on the slider 10 and electrically connected to the flat plug 6. A groove 11 is provided on the back of the flat sleeve, and the first ribbon cable board socket 9 of the circuit board 7 is located in the groove 11 and is plugged into (i.e., electrically connected to) the first ribbon cable board 8. The advantage of this design is that, Figure 3 and Figure 4 As shown, the tablet plug 6 is a Type-C plug, and the Type-C plug is located inside the cavity where the tablet is placed in the tablet sleeve 1. In order to smoothly insert the tablet into the cavity, the tablet plug 6 is set as a sliding structure, as shown. Figure 4 As shown, when the tablet plug 6 slides to the left, the plug will be removed from the cavity where the tablet is placed. After it is removed, the tablet can be easily placed into the cavity. Then, the tablet plug 6 is inserted into the tablet's Type-C interface, thus realizing the circuit connection between the computer and the circuit board 7.

[0054] In one possible implementation, such as Figure 5 As shown, the circuit board 7 is also provided with a second ribbon cable board 12, and the keyboard 2 is provided with a second ribbon cable board socket 13. The second ribbon cable board 12 extends into the housing of the keyboard 2 and is plugged into the second ribbon cable board socket 13.

[0055] In this embodiment, the second ribbon cable 12 extends from the circuit board 7 and is precisely inserted into the corresponding second ribbon cable socket 13 inside the keyboard 2 housing, so that power can be smoothly transmitted from the circuit board 7 to the keyboard 2, providing stable power support for the normal use of the keyboard 2, and ensuring that the user will not experience input interruption due to unstable circuit connection when using the keyboard 2 for text input and other operations.

[0056] In one possible implementation, such as Figure 7 As shown, a wire 14 is also embedded in the keyboard 2, and an electromagnetic coil 15 for charging the capacitive pen 5 is embedded in the charging pen sleeve 4. One end of the wire 14 is electrically connected to the keyboard 2, and the other end is electrically connected to the electromagnetic coil 15.

[0057] In this embodiment, when the tablet computer supplies power to the keyboard 2 via the tablet plug 6 and circuit board 7, the electrical energy is conducted along the wires 14 embedded in the keyboard 2. Since the other end of the wires 14 is connected to the electromagnetic coil 15 inside the charging pen sleeve 4, the electrical energy can smoothly reach the electromagnetic coil 15. After receiving the electrical energy, the electromagnetic coil 15 can wirelessly charge the capacitive pen 5 placed inside the charging pen sleeve 4 using the principle of electromagnetic induction. This ensures that the power of the capacitive pen 5 is replenished in a timely manner, so that the user does not have to worry about the capacitive pen 5 running out of power. The user can conveniently pick up the capacitive pen 5 at any time to draw, write annotations, and perform other operations on the tablet computer, ensuring the continuity and convenience of the usage process.

[0058] In one possible implementation, such as Figure 7 As shown, the charging pen sleeve 4 is also provided with a magnetic block 16 that is magnetically connected to the capacitive pen 5.

[0059] In this embodiment, the magnetic block 16 ensures that the capacitive pen 5 is firmly held in place after being placed in the charging pen sleeve 4, preventing it from easily falling out during daily carrying or when the tablet sleeve shakes, thus providing excellent fixation. Simultaneously, when the user needs to remove the capacitive pen 5, only a slight external force is required to easily remove it from the charging pen sleeve 4. This ensures the stability of the capacitive pen 5 while minimizing inconvenience in retrieval, further optimizing the tablet sleeve's functionality for storing and using the capacitive pen 5.

[0060] In one possible implementation, such as Figure 8 As shown, the charging pen sleeve 4 is provided with a spring-loaded component 17. The spring-loaded component 17 includes a spring 171 and a hook 172 that cooperate with each other. The hook 172 slides inside the charging pen sleeve 4 under the action of the spring 171, so as to lock the capacitive pen 5 and pop it out when pressed.

[0061] In this embodiment, when the capacitive pen 5 is inserted into the charging pen sleeve 4, its body first contacts the inclined surface of the hook 172. As the capacitive pen 5 continues to press down, the hook 172 slides laterally along the first guide groove of the charging pen sleeve 4 under the elastic force of the spring 171, until the snap-fit ​​structure at the end of the hook 172 is embedded in the positioning groove on the side of the charging pen sleeve 4. At this time, the spring 171 is in a compressed and energy-storing state. When it is necessary to remove the capacitive pen 5, the user applies vertical pressure, causing the tip of the capacitive pen 5 to squeeze the hook 172, triggering the unlocking of the hook 172. This forces the hook 172 to slide in the opposite direction along the second guide groove of the charging pen sleeve 4, causing the snap-fit ​​structure to disengage from the positioning groove. The compressed spring 171 instantly releases its elastic potential energy, pushing the capacitive pen 5 upwards, so that part of the capacitive pen 5 is exposed in the charging pen sleeve 4, making it easy for the user to grasp and use.

[0062] In one possible implementation, such as Figure 2 As shown, the edge of the flat plate sleeve 1 is also provided with a magnetic strip 18 that is magnetically fixed to the capacitive pen 5.

[0063] In this embodiment, the presence of the magnetic strip 18 provides an additional layer of secure fixation for the capacitive pen 5. When the capacitive pen 5 is not in use, in addition to being placed inside the charging pen sleeve 4 and secured by the magnetic block 16, it can also be attached to the magnetic strip 18 on the edge of the tablet sleeve 1. In certain special scenarios, such as when the tablet sleeve needs to be quickly moved and the capacitive pen 5 is not temporarily placed in the charging pen sleeve 4, the capacitive pen 5 can be securely fixed to the tablet sleeve 1 by the magnetic strip 18, preventing loss. This also makes it easier for the user to quickly find and retrieve the capacitive pen 5 when needed, increasing the flexibility and convenience of placing the capacitive pen 5.

[0064] In one possible implementation, such as Figure 1 and Figure 3 As shown, a flat plate support plate 19 is also hinged to the back of the flat plate sleeve 1.

[0065] In this embodiment, the tablet support plate 19 can be adjusted in angle according to the user's needs. In scenarios such as watching videos, conducting video conferences, or using the tablet as an e-reader, the user can flip the tablet support plate 19 to a suitable angle and then place the tablet case 1 on a flat surface such as a table, allowing the tablet to be supported by the tablet support plate 19, creating a comfortable viewing or operating angle. This reduces user fatigue from holding the tablet for extended periods and better meets the diverse needs for tablet placement angles in different usage scenarios, enhancing the practicality and multifunctionality of the tablet case 1.

[0066] In one possible implementation, such as Figure 1 and 4 As shown, the back of the flat plate sleeve 1 is also provided with a finger groove 20.

[0067] In this embodiment, the main function of the finger groove 20 is to facilitate the user to fasten the tablet support plate 19 fixed to the back of the tablet case 1. When the tablet support plate 19 needs to be opened for use, the user can insert their fingers into the finger groove 20 and, with the cooperation of the fingers and the finger groove 20, easily apply appropriate external force to rotate the tablet support plate 19 around the hinge to a suitable position to provide support for the tablet computer inside the tablet case 1.

[0068] In one possible implementation, such as Figure 1 As shown, the flat panel 1 also has a camera hole 21.

[0069] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
