[0003] However, most tablet cases on the market currently only offer basic protection, and some integrated keyboard cases have many shortcomings. For example, most cases connect the keyboard to the cover using traditional hinges or magnetic connections, which not only results in a large folded size but also makes the hinges or connecting shafts prone to damage, affecting lifespan. Furthermore, the connection points lack stable electrical connection design, easily leading to problems such as poor keyboard contact and disconnection. Existing cases with charging functions often have their charging ports located on the edge of the keyboard or cover, taking up space and limiting practicality. Utility Model Content

[0004] This invention aims to at least partially solve one of the problems in related technologies. Therefore, one of the objectives of this invention is to provide a thin and stable tablet protective case that achieves stable protection, efficient input, stable support, and a thin and light design for tablets, thereby improving the user experience.

[0005] A thin and stable tablet protective case includes a cover plate, a keyboard, and a spindle. The spindle is connected between the cover plate and the keyboard and is electrically connected to the keyboard. The spindle is a flat shaft with a rounded cuboid cross-section. One end of the spindle is provided with a charging port for providing power input to the keyboard or the tablet computer connected to the tablet protective case.

[0006] Furthermore, the bottom edge of the spindle is on the same plane as the bottom surface of the keyboard.

[0007] Furthermore, the spindle includes a fixed body and a rotating part. One side of the fixed body is fixedly connected to the cover plate, and the other side is rotatably connected to one end of the rotating part. The other end of the rotating part is connected to the keyboard, and the keyboard is electrically connected to the fixed body through the rotating part.

[0008] Furthermore, after the tablet case is connected to the tablet computer, the bottom edge of the tablet computer maintains a horizontal distance of 14 mm to 16 mm between it and the front row of keys on the keyboard.

[0009] Furthermore, the keyboard adopts a six-row key design, which includes an additional first row of hotkeys. The first row of hotkeys is located in the top area of ​​the keyboard, and the hotkeys may include, but are not limited to, function keys, shortcut keys, or system control keys.

[0010] Furthermore, the top surface, sides, and key areas of the keyboard are not covered by the covering material; only the bottom surface of the keyboard is covered by the covering material.

[0011] Furthermore, the covering material is waterproof leather.

[0012] Furthermore, the keyboard also includes a handwriting area, which is designed to be fully covered by a glass panel.

[0013] Furthermore, the cover plate includes a foldable A plate and a B plate, with one side of the A plate pivotally connected to the main shaft and the other side of the B plate pivotally connected to the B plate.

[0014] Furthermore, both plate A and plate B are made of fiberglass board material with a density of 0.8 g / cm³.

[0015] Compared with the prior art, the technical solution provided in this application has the following advantages: This application directly connects the cover plate and the keyboard via a spindle, replacing the traditional distributed connection structure (such as separate hinges or magnetic components), achieving integrated assembly of the cover plate and keyboard, reducing the number of parts, assembly complexity, and failure risk; and by utilizing the electrical connection between the spindle and the keyboard, it eliminates the need for additional wires or wireless connection modules, ensuring the stability of keyboard power supply and signal transmission, avoiding wireless connection disconnection, delay, or wire tangling problems, and improving the overall structural reliability and smoothness of use. The spindle adopts a flat shaft design, which significantly reduces the space occupied compared to the traditional cylindrical shaft, making the tablet protective case thinner and more portable after folding, suitable for everyday storage scenarios such as backpacks and tote bags; its cross-section is a rounded cuboid design, which avoids the safety hazards caused by sharp edges (such as scratching hands or snagging clothing), and can better fit the planar structure of the cover plate and keyboard, improving the overall appearance and grip comfort. The charging port located at one end of the spindle can flexibly power the keyboard, eliminating the need to carry multiple chargers or adapters. This is especially suitable for situations where users need to extend their battery life while working or studying on the go. At the same time, the charging port is integrated into the spindle rather than the cover or the edge of the keyboard, avoiding taking up the protective space of the cover or the keyboard operating area, optimizing the overall layout and improving ease of use.

[0022] like Figure 1 - Figure 5As shown, this application provides a thin and stable tablet protective case, including a cover plate 10, a keyboard 20, and a spindle 30. The spindle 30 is connected between the cover plate 10 and the keyboard 20, and is electrically connected to the keyboard 20. The spindle 30 is a flat shaft with a rounded cuboid cross-section. One end of the spindle 30 is provided with a charging port 33, which is used to provide power input to the keyboard 20 or the tablet computer 40 connected to the tablet protective case.

[0023] The spindle 30, as the core component connecting the cover plate 10 and the keyboard 20, adopts a flat, rounded cuboid structure design. This structure ensures the support strength of the spindle 30 while avoiding safety hazards caused by sharp edges. One end of the spindle 30 (e.g., the right side) has a Type-C charging port 33, which supports a 5V / 2A power supply specification. It can be connected to a power adapter via an external power cord to power the keyboard 20. Simultaneously, when the tablet computer 40 is fixedly connected to the cover plate 10, it can be charged via the tablet's built-in data cable connected to the charging port 33, meeting the simultaneous power supply needs of multiple devices.

[0024] Furthermore, the bottom edge of the spindle 30 is on the same plane as the bottom surface of the keyboard 20.

[0025] This design ensures that the tablet case remains stable when placed on a flat surface such as a desktop, preventing the case from tilting due to the protrusion of the spindle 30, which could affect the stability of the keyboard 20 input or the tablet's placement.

[0026] Furthermore, the spindle 30 includes a fixed body 31 and a rotating part 32. One side of the fixed body 31 is fixedly connected to the cover plate 10, and the other side is rotatably connected to one end of the rotating part 32. The other end of the rotating part 32 is connected to the keyboard 20, and the keyboard 20 is electrically connected to the fixed body 31 through the rotating part 32.

[0027] The fixed connection between the fixed body 31 and the cover plate 10 ensures the support strength of the cover plate 10, while the rotating part 32 can realize multi-angle rotation between the keyboard 20 and the cover plate 10 (the rotation angle range can be designed to be 0°-180°) to meet the user's usage needs in different scenarios (such as upright tablet office, tilted movie viewing, etc.); at the same time, the electrical connection design between the rotating part 32 and the fixed body 31 can avoid setting up additional wires, reduce the risk of connection failure, and ensure the stability of power supply and data transmission for the keyboard 20.

[0028] The spindle 30 consists of a fixed body 31 and a rotating part 32. The fixed body 31 is made of ABS plastic and is fixedly connected to one side (such as the bottom edge) of the A plate 11 of the cover plate 10 by screws, providing high connection strength and preventing it from easily falling off. The rotating part 32 is made of metal alloy (such as aluminum alloy) and is rotatably connected to the fixed body 31 via a damping shaft. The rotation damping is adjustable to ensure smooth and wobbly rotation and allows for positioning at any angle within the range of 0°-180°. The other end of the rotating part 32 is fixedly connected to the keyboard 20 via a snap-fit ​​structure. Simultaneously, the rotating part 32 has copper conductive contacts inside, which contact the wires inside the fixed body 31 and the circuit module of the keyboard 20, achieving an electrical connection between the keyboard 20 and the spindle 30. This ensures stable transmission of input signals from the keyboard 20 and avoids latency issues associated with wireless connections.

[0029] Furthermore, after the tablet protective case is connected to the tablet computer 40, the bottom edge of the tablet computer 40 maintains a horizontal distance of 14 mm to 16 mm between it and the front row of keys of the keyboard 20.

[0030] This spacing design is ergonomic, preventing discomfort to users' hands from being too close to the bottom of the tablet when using the keyboard 20 for input. It also provides space for heat dissipation at the bottom of the tablet, preventing the tablet from overheating and affecting performance due to prolonged use.

[0031] Furthermore, the keyboard 20 adopts a six-row key design, which includes an additional first row of hotkeys 21. The first row of hotkeys 21 is located in the top area of ​​the keyboard 20. The hotkeys may include, but are not limited to, function keys, shortcut keys, or system control keys.

[0032] The keyboard 20 adopts a six-row key design, including an additional first row of hotkeys 21 located at the top of the keyboard 20. These hotkeys may include, but are not limited to, function keys (such as F1-F12), shortcut keys (such as quickly opening a browser or document software), or system control keys (such as adjusting brightness, volume, or locking the screen). Compared to the traditional five-row key design, the six-row key design increases the hotkey area, significantly improving operational efficiency and meeting users' needs for quick function access, making it particularly suitable for office scenarios.

[0033] Furthermore, the top surface, sides, and key areas of the keyboard 20 are not covered by the covering material; only the bottom surface of the keyboard 20 is covered by the covering material.

[0034] This design ensures heat dissipation performance of the top surface and key area of ​​the keyboard 20, and prevents the covering material from affecting the key feel. At the same time, the covering material on the bottom surface can protect the bottom of the keyboard 20 from wear or dust, balancing practicality and feel.

[0035] Furthermore, the covering material is waterproof leather.

[0036] Waterproof leather not only has excellent waterproof performance, preventing liquid splashes from damaging the internal circuitry of the keyboard, but also enhances the overall texture of the protective case. The leather material is soft, making it easy to fold and store, and it also has a certain degree of anti-slip performance, making it more stable when placed.

[0037] Furthermore, the keyboard 20 also includes a handwriting area 22, which is designed to cover the entire area and has a glass panel on its surface.

[0038] The full-area handwriting area 22 provides a larger writing space to meet users' needs for large-scale handwriting input, drawing, etc.; the glass panel has high light transmittance, high smoothness and wear resistance, the pen stroke is smooth when writing and it is not easy to scratch, which can maintain a good user experience for a long time. At the same time, the glass panel is easy to clean and can be quickly wiped clean after stains.

[0039] Furthermore, the cover plate 10 includes a foldable A plate 11 and a B plate 12, with one side of the A plate 11 pivotally connected to the main shaft 30 and the other side pivotally connected to the B plate 12.

[0040] The foldable design of the A-board 11 and the B-board 12 allows for multi-angle support of the cover plate 10: when the tablet is placed on the A-board 11, the tilt angle of the A-board 11 can be adjusted by folding the B-board 12 (e.g., 30°-60°), meeting the viewing angle needs of users in different scenarios such as typing, watching movies, and reading; at the same time, the folded cover plate 10 can completely cover the front and back of the tablet computer 40, improving protection performance and preventing the tablet screen and back from being scratched or damaged by collision.

[0041] The inner side of plate A11 is provided with a silicone anti-slip pad. When the tablet computer 40 is placed on plate A11, the silicone pad can increase friction and prevent the tablet from sliding. One side of plate A11 is pivotally connected to the fixing body 31 of the main shaft 30 through a damping hinge, and the other side is pivotally connected to plate B12 through the same damping hinge. The size of plate B12 is the same as that of plate A11. When folding protection is required, plate B12 can be folded towards plate A11 to completely cover the screen of tablet computer 40. The inner side of plate B12 is provided with microfiber velvet to prevent scratching the tablet screen.

[0042] Furthermore, both the A plate 11 and the B plate 12 are made of fiberglass board material with a density of 0.8 g / cm³.

[0043] Fiberglass board material has the characteristics of high strength and lightweight, with a density of only 0.8 grams per cubic centimeter, which is much lower than that of traditional metal or plastic materials. This can significantly reduce the overall weight of the protective case and improve portability. At the same time, fiberglass board has excellent impact resistance and wear resistance, which can effectively protect the tablet computer from damage caused by accidental collisions or drops, and it is not easily deformed after long-term use.

[0044] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
