Description

Technical Field

[0001] This utility model relates to the field of multifunctional leather keyboard technology, and more specifically, to a multifunctional leather keyboard. Background Technology

[0002] In some existing technologies, a mounting shell is attached to one side of the keyboard case to hold a tablet, creating a simplified laptop. This design aims to meet users' dual needs for portability and functionality during mobile work and study. However, traditional methods of connecting the mounting shell and the keyboard case typically involve screws, clips, or adhesive. These methods present several inconveniences in practical use. Specifically, screw fixing requires the use of screwdrivers or other specialized tools for tightening and loosening, which is particularly difficult in low-light or confined spaces. Clip-on fixing, while relatively simple, often requires operating multiple clips simultaneously and applying considerable force, making it prone to damage due to improper operation. Adhesive fixing, while easy to install, can easily damage the surface of the keyboard case during disassembly, and its adhesive strength decreases after repeated use, affecting the fixing effect. Therefore, the installation and disassembly of the mounting shell and keyboard case in existing technologies are usually cumbersome, requiring specialized tools and hindering convenient separation and assembly, thus impacting the user experience and practicality of the product.

[0003] Secondly, while some devices achieve convenient installation and removal of the mounting shell and the leather keyboard body through the cooperation of certain components, these methods improve the convenience of installation and removal to a certain extent. However, their structural design is relatively simple and crude, mainly manifested in the imperfect locking mechanism. In daily use, their stability is insufficient, and they are easily affected by various external forces, leading to structural loosening or even detachment. Specifically, when the user moves the device, the leather keyboard will be subjected to external forces such as vibration and impact. These external forces will generate repeated stress impacts on the connection points, causing the originally firmly connected components to gradually loosen. When the user types on the keyboard, the striking force will be transmitted through the keyboard body to the connection points. Over time, this will cause the components to shift and loosen, resulting in a decrease in connection strength. When the connection points completely detach, the tablet may fall and be damaged, causing economic losses and inconvenience to the user. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a multifunctional leather keyboard case to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional leather keyboard case, comprising a keyboard body, a fixed sleeve on one side of the keyboard body, a quick-release lever and a quick-release sleeve detachably disposed within the fixed sleeve, the quick-release sleeve being detachably fitted onto one end of the quick-release lever, a rotating plate rotatably disposed on the outer side of the quick-release sleeve, the rotating plate having a circular hole and an arc-shaped groove, the circular hole being located at one end of the arc-shaped groove, a limiting sleeve slidably disposed on the outer side of the quick-release sleeve, a circular rod fixedly connected to one side of the limiting sleeve, and a circular plate fixedly disposed on the circular rod. Furthermore, the circular plate is provided in two places. A rotating sleeve is provided on the outer side of the quick-release sleeve. An unlocking groove is opened in the rotating sleeve with a variable diameter. A rotating frame is fixedly provided on one side of the rotating sleeve. An unlocking plate is slidably provided in the unlocking groove. A limiting rod is slidably provided in the rotating frame. A limiting plate is connected to one end of the limiting rod. Multiple limiting grooves are opened on the outer side of the quick-release sleeve. A quick-release groove is opened on the outer side of the quick-release rod. One end of the limiting rod is inserted into the limiting groove. A quick-release block is fixedly connected to one side of the unlocking plate. The quick-release block is inserted into the quick-release groove.

[0008] The present invention is further configured such that a mounting shell is movably provided on one side of the keyboard body, a connecting sleeve is fixedly provided on one side of the mounting shell, and one end of the quick-release lever passes through the fixed sleeve and the connecting sleeve and enters the inside of the quick-release sleeve.

[0009] The present invention is further configured such that a plurality of damping plates are detachably provided in the fixed sleeve, thereby providing a plurality of detachable damping plates in the fixed sleeve.

[0010] The present invention is further provided that each of the plurality of damping sheets has a rubber ring at both ends.

[0011] The present invention is further configured such that a spring is connected to one side of the limiting sleeve, the spring is movably sleeved on the outside of the round rod, and the other end of the spring abuts against one side of the rotating plate. Through the elastic restoring action of the spring, the limiting sleeve can automatically return to the initial position after the operation is completed, which simplifies the operation process.

[0012] The present invention is further configured such that a connecting spring is movably sleeved on the outer side of the limiting rod, and the two ends of the connecting spring are respectively connected to the limiting plate and the limiting frame. The connecting spring connects the limiting plate and the limiting frame, forming an elastic connection mechanism, which can provide a stable restoring force during the sliding of the limiting rod, ensuring that the limiting rod can be accurately inserted into the limiting groove.

[0013] The present invention is further configured such that one end of the limiting rod and the edge of the inner wall of the limiting groove are both designed with rounded corners. The rounded corner design eliminates sharp edges, making the limiting rod easier to insert and remove from the limiting groove, and reducing jamming caused by interference from sharp corners.

[0014] The present invention is further configured such that the quick-lock slot is formed in a ring structure on the outside of the quick-lock rod. Through the ring structure design, the quick-lock block can be inserted into the quick-lock slot from any direction, which improves the fault tolerance of assembly and simplifies the alignment operation.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a multi-functional leather keyboard case, which has the following advantages:

[0017] 1. By incorporating a quick-release mechanism consisting of components such as a quick-release lever, quick-release sleeve, rotating sleeve, quick-release block, and unlocking plate, convenient installation and disassembly between the mounting shell and the keyboard body are achieved. When disassembly is required, first rotate the rotating sleeve in the forward direction to lock the quick-release lever and quick-release sleeve. Then, remove the quick-release lever and quick-release sleeve to separate the mounting shell from the keyboard body. The entire process does not require the use of screwdrivers or other professional tools, making the operation simple and intuitive. When assembly is required, pass the quick-release lever through the fixing sleeve and connecting sleeve from one side, and then fit the quick-release sleeve onto the outside of the quick-release lever from the other side. With the reset operation of the rotating sleeve and other components, the connection between the mounting shell and the keyboard body can be quickly completed. This design effectively solves the problems of existing technologies, such as screw fixing requiring professional tools, buckle locking requiring simultaneous operation of multiple buckle points and application of large force, and adhesive fixing easily damaging the surface of the leather case during disassembly. It also avoids the inconvenience of increased operation difficulty in low light or confined spaces, significantly improving the user experience and practicality of the product.

[0018] 2. This device is designed with a multi-locking mechanism, including a rotating plate, a round rod, a round plate, a limiting rod, a limiting plate, a limiting groove, and a connecting spring. This ensures the structural stability of the mounting shell and the keyboard body after connection. After connection, the limiting rod is inserted into the limiting groove to form a lock. Then, by operation, the round rod and round plate cooperate to limit the limiting sleeve to one side of the rotating plate, preventing the limiting sleeve from sliding easily. The inner wall of the limiting sleeve limits the outer wall of the limiting plate, preventing the limiting plate and limiting rod from sliding outward. The limiting rod and limiting groove cooperate to limit the rotating frame, preventing the rotating frame and rotating sleeve from rotating accidentally. This multi-locking design effectively solves the problems of imperfect locking mechanisms and insufficient connection strength in existing technologies. It can effectively resist the vibration and impact forces generated by the user during movement, avoiding the problem of repeated stress impacts on the connection parts caused by these external forces, which leads to the gradual loosening of the components. It also solves the problem of the impact force transmitted to the connection parts by the keyboard body during use, which leads to the long-term accumulation of component displacement and loosening. It prevents the connection parts from completely falling off, causing the tablet to fall and be damaged, resulting in economic losses and inconvenience to the user, and ensuring the stability and reliability of the connection.

[0028] Please see Figures 1-5A multifunctional leather keyboard case includes a keyboard body 1. A fixing sleeve 2 is provided on one side of the keyboard body 1. A quick-release lever 3 and a quick-release sleeve 4 are detachably provided in the fixing sleeve 2. The quick-release sleeve 4 is detachably fitted onto one end of the quick-release lever 3. A rotating plate 5 is rotatably provided on the outer side of the quick-release sleeve 4. The rotating plate 5 has a round hole 6 and an arc-shaped groove 7, with the round hole 6 located at one end of the arc-shaped groove 7. A limiting sleeve 8 is slidably fitted onto the outer side of the quick-release sleeve 4. A round rod 9 is fixedly connected to one side of the limiting sleeve 8. A round plate 10 is fixedly provided on the round rod 9, and the round plate 10 has two locations. A rotating sleeve 11 is provided, and an unlocking groove 12 is provided in the rotating sleeve 11 with a variable diameter. A rotating frame 13 is fixedly provided on one side of the rotating sleeve 11. An unlocking plate 14 is slidably provided in the unlocking groove 12. A limiting rod 15 is slidably provided in the rotating frame 13. A limiting plate 16 is connected to one end of the limiting rod 15. Multiple limiting grooves 17 are provided on the outside of the quick-lock sleeve 4. A quick-lock groove 18 is provided on the outside of the quick-lock rod 3. One end of the limiting rod 15 is inserted into the limiting groove 17. A quick-lock block 19 is fixedly connected to one side of the unlocking plate 14. The quick-lock block 19 is inserted into the quick-lock groove 18.

[0029] The keyboard body 1 has a movable mounting shell 20 on one side, and a connecting sleeve 21 is fixedly mounted on one side of the mounting shell 20. One end of the quick-release lever 3 passes through the fixed sleeve 2 and the connecting sleeve 21 and enters the inside of the quick-release sleeve 4.

[0030] The fixed sleeve 2 is provided with multiple detachable damping plates 22.

[0031] Each of the multiple damping plates 22 has a rubber ring 23 at both ends.

[0032] In this embodiment, when it is necessary to separate the mounting shell 20 and the keyboard body 1, firstly, rotate the rotating plate 5 in the forward direction, so that the rotating plate 5 drives the circular hole 6 and the arc groove 7 to rotate in the forward direction. When the circular hole 6 rotates to a position concentric with the circular plate 10, stop rotating the rotating plate 5. Then push the limiting sleeve 8. The limiting sleeve 8 will drive the circular rod 9 and the circular plate 10 on one side to gradually slide into the circular hole 6. The limiting sleeve 8 will cooperate with the rotating plate 5 to compress the spring 24. When the spring 24 is compressed to its limit, the circular plate 10 near the limiting sleeve 8 just slides through the circular hole 6 and moves to the other side of the rotating plate 5. Then rotate the rotating plate 5 in the reverse direction, so that the rotating plate 5 drives the circular hole 6 and the arc groove 7 to rotate in the reverse direction. At this time, the circular rod 9 will enter the arc groove 7. When the circular rod 9 is at one end of the arc groove 7, stop rotating the circular plate 10. At this time, the limiting sleeve 8 no longer limits the outer wall of the limiting plate 16. Then rotate the rotating sleeve 11 in the forward direction. The sleeve 11 will drive the rotating frame 13 on one side to rotate in the forward direction, and the rotating frame 13 will drive the limiting rod 15, the limiting plate 16 and the connecting spring 25 to rotate in the forward direction. Then the inner wall of the limiting groove 17 will press one end of the limiting rod 15. Due to the rounded corner structure design at the edge of the inner wall of the limiting groove 17, one end of the limiting rod 15 will slide out of the limiting groove 17, and the other end of the limiting rod 15 will drive the connecting spring 25 to be stretched outward through the limiting plate 16. At the same time, the rotating sleeve 11 will drive the inner variable diameter opening of the unlocking groove 12 to rotate in the forward direction. Then the unlocking plate 14 will move in the unlocking groove 12 and drive the quick-lock block 19 installed on one side to slide outward, so that the quick-lock block 19 will gradually slide out of the quick-lock groove 18. Then the quick-lock rod 3 and the quick-lock sleeve 4 will be pulled to both sides respectively, so that the quick-lock rod 3 and the quick-lock sleeve 4 can be removed. Then the mounting shell 20 can be removed from one side of the keyboard body 1.

[0033] Please see Figure 3 and Figure 4 As a further implementation of the overall equipment: a spring 24 is connected to one side of the limiting sleeve 8, the spring 24 is movably sleeved on the outside of the round rod 9, and the other end of the spring 24 abuts against one side of the rotating plate 5.

[0034] A connecting spring 25 is movably sleeved on the outside of the limiting rod 15, and the two ends of the connecting spring 25 are connected to the limiting plate 16 and the limiting frame, respectively.

[0035] Both the end of the limiting rod 15 and the edge of the inner wall of the limiting groove 17 adopt a rounded corner structure design.

[0036] The quick-release slot 18 is a ring structure located on the outside of the quick-release lever 3.

[0037] More specifically, when the mounting shell 20 needs to be assembled onto one side of the keyboard body 1, firstly, multiple damping plates 22 are stacked and filled into the fixing sleeve 2. Then, rubber rings 23 are installed on both sides of the damping plates 22. Next, the connecting sleeve 21 is concentrically aligned with the fixing sleeve 2. Then, the quick-release lever 3 passes through the fixing sleeve 2 and the connecting sleeve 21 from one side. Then, the quick-release sleeve 4 is fitted onto the outside of the quick-release lever 3 from the other side, so that the quick-release sleeve 4 and the quick-release lever 3 cooperate to compress the damping plates 22, and the rubber rings 23 on both sides of the connecting sleeve 21 are compressed to the outside of the connecting sleeve 21. Then, the process is reversed. Rotating the rotating sleeve 11 causes it to drive one side of the rotating frame 13 to rotate in the opposite direction. This, in turn, causes the limiting rod 15, the limiting plate 16, and the connecting spring 25 to rotate in the opposite direction. Simultaneously, the rotating sleeve 11 causes the inner unlocking groove 12 to rotate in the opposite direction. Then, the unlocking block causes one side of the quick-locking block 19 to gradually slide inward and reset, so that the quick-locking block 19 re-locks into the quick-locking groove 18. At this point, the rotating frame 13 drives the limiting rod 15 and other components to rotate to the position corresponding to the original limiting groove 17. Then, the connecting spring 25 resets and pulls the limiting plate. 16. This causes the limiting plate 16 to slide the limiting rod 15 inward to reset. Then, one end of the limiting rod 15 will slide into the original limiting groove 17. Then, the rotating plate 5 will rotate clockwise again, causing the rotating plate 5 to drive the circular hole 6 and the arc groove 7 to rotate clockwise. When the circular hole 6 rotates to the position concentric with the circular plate 10, the spring 24 pushes the limiting sleeve 8 to slide and reset. Then, the limiting sleeve 8 will drive the circular rod 9 on one side and the two circular plates 10 to slide and reset. When the spring 24 is fully reset, the circular plate 10 at the top of the circular rod 9 slides to the original side of the rotating plate 5, and then... Rotating the rotating plate 5 in the opposite direction causes the circular hole 6 and the arc groove 7 to rotate and reset to a position that does not correspond to the circular plate 10 and the circular rod 9. Then, the circular rod 9 and the top circular plate 10 cooperate to limit the limiting sleeve 8 to one side of the rotating plate 5, so that the limiting sleeve 8 cannot slide easily. Then, the inner wall of the limiting sleeve 8 limits the outer wall of the limiting plate 16, so that the limiting plate 16 and the limiting rod 15 cannot slide outward. Then, the limiting rod 15 and the limiting groove 17 cooperate to limit the rotating frame 13, preventing the rotating frame 13 and the rotating sleeve 11 from rotating unexpectedly, thereby ensuring the connection stability.

[0038] In summary, during the use or operation of the overall device: when it is necessary to separate the mounting shell 20 and the keyboard body 1, first rotate the rotating plate 5 in the forward direction, causing the rotating plate 5 to drive the circular hole 6 and the arc groove 7 to rotate in the forward direction. When the circular hole 6 rotates to a position concentric with the circular plate 10, stop rotating the rotating plate 5. Then push the limiting sleeve 8. The limiting sleeve 8 will drive the circular rod 9 and the circular plate 10 on one side to gradually slide into the circular hole 6. The limiting sleeve 8 will cooperate with the rotating plate 5 to compress the spring 24. When the spring 24 is compressed to its limit, the circular plate 10 near the limiting sleeve 8 will just slide through the circular hole 6 and move to the other side of the rotating plate 5. Then rotate the rotating plate 5 in the reverse direction, causing the rotating plate 5 to drive the circular hole 6 and the arc groove 7 to rotate in the reverse direction. At this time, the circular rod 9 will enter the arc groove 7. When the circular rod 9 is at one end of the arc groove 7, stop rotating the circular plate 10. At this time, the limiting sleeve 8 no longer limits the outer wall of the limiting plate 16. Then rotate the rotating sleeve in the forward direction. 11. The rotating sleeve 11 will drive the rotating frame 13 on one side to rotate in the forward direction, and the rotating frame 13 will drive the limiting rod 15, the limiting plate 16 and the connecting spring 25 to rotate in the forward direction. Then the inner wall of the limiting groove 17 will press one end of the limiting rod 15. Due to the rounded corner structure design at the edge of the inner wall of the limiting groove 17, one end of the limiting rod 15 will slide out of the limiting groove 17, and the other end of the limiting rod 15 will drive the connecting spring 25 to be stretched outward through the limiting plate 16. At the same time, the rotating sleeve 11 will drive the inner variable diameter opening of the unlocking groove 12 to rotate in the forward direction. Then the unlocking plate 14 will move in the unlocking groove 12 and drive the quick-lock block 19 installed on one side to slide outward, so that the quick-lock block 19 will gradually slide out of the quick-lock groove 18. Then the quick-lock rod 3 and the quick-lock sleeve 4 will be pulled to both sides respectively, so that the quick-lock rod 3 and the quick-lock sleeve 4 can be removed. Then the mounting shell 20 can be removed from one side of the keyboard body 1.

[0039] When the mounting shell 20 needs to be assembled onto one side of the keyboard body 1, firstly, multiple damping plates 22 are stacked and filled into the fixing sleeve 2. Then, rubber rings 23 are installed on both sides of the damping plates 22. Next, the connecting sleeve 21 is concentrically aligned with the fixing sleeve 2. Then, the quick-release lever 3 passes through the fixing sleeve 2 and the connecting sleeve 21 from one side. Then, the quick-release sleeve 4 is fitted onto the outside of the quick-release lever 3 from the other side, so that the quick-release sleeve 4 and the quick-release lever 3 cooperate to squeeze the damping plates 22, and the rubber rings 23 on both sides of the connecting sleeve 21 are squeezed to the outside of the connecting sleeve 21. Then, the reverse rotation is performed. The rotating sleeve 11 causes one side of the rotating frame 13 to rotate in the opposite direction. This, in turn, causes the limiting rod 15, the limiting plate 16, and the connecting spring 25 to rotate in the opposite direction. Simultaneously, the rotating sleeve 11 causes the inner unlocking groove 12 to rotate in the opposite direction. Then, the unlocking block causes one side of the quick-locking block 19 to gradually slide inwards and reset, allowing the quick-locking block 19 to re-engage in the quick-locking groove 18. At this point, the rotating frame 13 causes the limiting rod 15 and other components to rotate to the position corresponding to the original limiting groove 17. Finally, the connecting spring 25 resets and pulls the limiting plate 16. This causes the limiting plate 16 to slide the limiting rod 15 inward to reset. Then, one end of the limiting rod 15 will slide into the original limiting groove 17. Then, the rotating plate 5 will rotate forward again, causing the rotating plate 5 to drive the circular hole 6 and the arc groove 7 to rotate forward. When the circular hole 6 rotates to the position concentric with the circular plate 10, the spring 24 pushes the limiting sleeve 8 to slide back to reset. Then, the limiting sleeve 8 will drive the circular rod 9 on one side and the two circular plates 10 to slide back to reset. When the spring 24 is fully reset, the circular plate 10 at the top of the circular rod 9 slides to the original side of the rotating plate 5, and then reverses again. Rotating the rotating plate 5 causes the circular hole 6 and the arc groove 7 to rotate and reset to a position that does not correspond to the circular plate 10 and the circular rod 9. Then, the circular rod 9 and the top circular plate 10 cooperate to limit the limiting sleeve 8 to one side of the rotating plate 5, so that the limiting sleeve 8 cannot slide easily. Then, the inner wall of the limiting sleeve 8 limits the outer wall of the limiting plate 16, so that the limiting plate 16 and the limiting rod 15 cannot slide outward. Then, the limiting rod 15 and the limiting groove 17 cooperate to limit the rotating frame 13, preventing the rotating frame 13 and the rotating sleeve 11 from rotating unexpectedly, thereby ensuring the connection stability.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
