Description

Technical Field

[0001] The utility model relates to the technical field of keyboard shafts, and more specifically, to an elliptical main shaft of a magic keyboard. Background Art

[0002] The Magic Keyboard is used by Apple companies such as iPhones and tablets, supports M1-MAC, and has Bluetooth, Lightning port, and wireless. It is a keyboard that assists mobile terminals. When using the Magic Keyboard, in order to facilitate use, it is generally supported by a panel and a device. The rotation of the panel is generally achieved through a hinge.

[0003] However, the existing Magic Keyboard's oval spindle has the following problems when in use:

[0004] (1) When adjusting the angle between the Magic Keyboard and iPad for use, the angle can easily change due to slight external force or vibration. For example, when a user's arm accidentally touches the keyboard or iPad while typing, the angle may shift, affecting the user experience and the accuracy of operation.

[0005] (2) Secondly, users may excessively rotate the keyboard and iPad when adjusting the angle, causing excessive pressure on the connecting parts. Such excessive rotation may cause unnecessary distortion and wear of the internal components of the hinge mechanism, such as the shaft core and sleeve, thereby reducing the service life of the entire elliptical main shaft.

[0006] This utility model can form a stable connection state after the user adjusts the Magic Keyboard and iPad to a specific angle, effectively preventing angle changes caused by slight external force collision or vibration, and can limit the rotation angle to prevent the connection part from being subjected to excessive pressure. Utility Model Content

[0007] The present invention aims to solve the technical problems raised by the above-mentioned background technology and provides an elliptical main axis of a magic control keyboard.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an elliptical main shaft of a magic control keyboard, comprising: a first aluminum alloy plate, a second aluminum alloy plate nested at the bottom of the first aluminum alloy plate, sealing covers are provided at both ends of the left and right sides of the second aluminum alloy plate, a rotating shaft mechanism is embedded in the bottom of the first aluminum alloy plate, a torsion spring mechanism is provided on the other side of the rotating shaft mechanism, the rotating shaft mechanism includes an axis core, a limit block, a sleeve, a convex bump, a silencer, a spring assembly and a nut, one end of the axis core passes through the limit block, the sleeve, the convex bump, the silencer, the spring assembly in sequence and is threadedly connected to the nut, and the torsion spring mechanism includes a torsion spring fixed axis A, a torsion spring and a torsion spring fixed axis B.

[0009] A further preferred solution is that a first through groove is provided at the bottom of the first aluminum alloy plate, the rotating shaft mechanism is placed in the first through groove, and the number of the rotating shaft mechanisms is two.

[0010] A further preferred solution: a second through groove is opened in the middle of the second aluminum alloy plate, and the second through groove is nested outside the first through groove at the bottom of the first aluminum alloy plate. Sealing grooves are opened at both ends of the second aluminum alloy plate, and the sealing grooves are connected to the second through grooves, and the sealing cover is embedded in the sealing groove.

[0011] A further preferred solution: a limiting block, a sleeve, a convex bump, a silencer and a spring assembly are nested in sequence on the left side of the shaft core surface, a limiting boss is fixedly mounted on one end of the sleeve, a groove is provided on the other end of the sleeve, and a self-locking boss is fixedly installed on one end of the convex bump.

[0012] A further preferred solution is that the limiting boss is matched with the limiting block, the self-locking boss is matched with the groove, and the other end of the shaft core is interference fit with the first aluminum alloy plate.

[0013] A further preferred solution is that the torsion spring fixed axis A is interference-connected with the rotating shaft on one side, and the torsion spring is connected between the torsion spring fixed axis A and the torsion spring fixed axis B.

[0014] Beneficial effects:

[0015] 1. By providing a self-locking boss and groove, and utilizing the rotational cooperation between the self-locking boss and the groove, when the shaft sleeve and the convex hull rotate relative to each other, the self-locking boss on one end of the hull will cooperate with the groove on the other end of the shaft sleeve at a specific angle. This cooperation is similar to a mechanical lock. When the self-locking boss enters the groove, a stable connection state is formed, thereby limiting further relative rotation of the shaft sleeve and the hull, realizing the self-locking function. When using the Magic Keyboard, users may need to fix the keyboard and iPad at a specific angle to meet different usage requirements. The self-locking function ensures that after adjusting to the desired angle, the spindle can stably maintain the angle and will not change the angle due to slight external force or vibration, thereby improving the stability and reliability of use.

[0016] 2. By providing a limiting boss and a limiting block, the limiting boss at one end of the sleeve cooperates with the limiting block. When the shaft core rotates, the sleeve also rotates. The limiting boss contacts the limiting block during the rotation process, and the position of the limiting block is fixed. When the limiting boss contacts the limiting block, the rotation angle of the sleeve reaches its limit. This contact restricts further rotation of the sleeve and the shaft core connected to it, thereby limiting the rotation angle of the hinge mechanism. When using the Magic Keyboard, if there is no limiting function, the user may over-rotate the keyboard and iPad, causing damage to the connection part or affecting the user experience. The limiting function can ensure that the hinge mechanism rotates within a safe angle range, avoiding damage to the device due to excessive rotation;

[0017] 3. In summary, the elliptical main shaft of the Magic Keyboard is equipped with structures such as a rotating shaft mechanism and a torsion spring mechanism. In terms of the rotating shaft mechanism, the shaft core passes through the limit block, the shaft sleeve, the convex bump, the silencer and the shrapnel assembly in sequence and is threadedly connected to the nut. The various components work together to ensure the smoothness and accuracy of the rotation. At the same time, the shaft sleeve reduces the friction between the shaft core and other components, the silencer effectively reduces the noise generated during the rotation process, and the shrapnel assembly provides a damping sense for the rotating shaft, further enhancing the comfort and stability of the operation. The torsion spring fixed shaft A, the torsion spring and the torsion spring fixed shaft B in the torsion spring mechanism cooperate with each other, and the torsion spring fixed shaft A is interference connected with the rotating shaft on one side, ensuring the firmness and stability of the connection. When the rotating shaft rotates, the torsion spring fixed shaft A drives the torsion spring to generate torque, so that the main shaft can automatically reset or maintain a specific angle position after rotating to a certain angle, providing great convenience for users.

[0025] The following is a combination of the appended examples of the present invention Figures 1-6 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0026] See also Figure 1-6In an embodiment of the present invention, an elliptical main shaft of a magic control keyboard includes: a first aluminum alloy plate 1, a second aluminum alloy plate 2 is nested at the bottom of the first aluminum alloy plate 1, and sealing covers 3 are provided at both ends of the left and right sides of the second aluminum alloy plate 2. A rotating shaft mechanism 4 is embedded and installed at the bottom of the first aluminum alloy plate 1, and a torsion spring mechanism 5 is provided on the other side of the rotating shaft mechanism 4. The rotating shaft mechanism 4 includes a shaft core 401, a limit block 402, a shaft sleeve 403, a convex bulge 406, a silencer 408, a spring assembly 409 and a nut 410. One end of the shaft core 401 passes through the limit block 402, the shaft sleeve 403, the convex bulge 406, the silencer 408, the spring assembly 409 and is threadedly connected to the nut 410. The torsion spring mechanism 5 includes a torsion spring fixed shaft A501, a torsion spring 502 and a torsion spring fixed shaft B503. The left and right ends of the second aluminum alloy plate 2 are respectively provided with sealing grooves 202, which are communicated with the second through groove 201, and the sealing cover 3 is embedded in the sealing groove 202. The first aluminum alloy plate 1 and the second aluminum alloy plate 2 provide a solid frame for the entire spindle structure. The aluminum alloy material has the advantages of high strength, light weight, and corrosion resistance, which can ensure the stability and reliability of the spindle during long-term use. The nested design of the two layers of aluminum alloy plates may help to improve the integrity and stability of the structure, and may also provide better protection for the internal rotating shaft mechanism 4 and the torsion spring mechanism. The sealing cover 3 is arranged on the second aluminum alloy plate. The left and right ends of the gold plate 2 are tightly matched with the sealing groove 202 to play a sealing role, which can prevent impurities such as dust and moisture from entering the interior of the main shaft, thereby protecting the internal rotating shaft mechanism 4 and the torsion spring mechanism 5 from damage. The shaft core 401 is the core component of the rotating shaft mechanism 4. It passes through the limit block 402, the shaft sleeve 403, the convex bump 406, the silencer 408, the shrapnel assembly 409 and is threadedly connected with the nut 410 to realize the function of the rotating shaft. The torsion spring fixed shaft A501, the torsion spring 502 and the torsion spring fixed shaft B503 constitute the torsion spring mechanism 5. The torsion spring 502 can provide a certain torque, so that the main shaft can automatically reset or maintain a specific angular position after rotating to a certain angle. When the user needs to adjust the angle between the Magic Keyboard and the iPad, external force is applied to rotate the keyboard or iPad around the elliptical main axis. The shaft core 401 in the hinge mechanism 4, with the cooperation of the shaft sleeve 403 and other components, achieves smooth rotation. At the same time, the torsion spring mechanism 5 generates corresponding torque according to the angle of rotation. After the user adjusts the keyboard and iPad to the desired angle, the external force is stopped. At this time, the torque of the torsion spring mechanism 5 keeps the keyboard and iPad at this angle position. During use, the shaft sleeve 403 reduces the friction between the shaft core 401 and other components, ensuring smooth rotation. The sound-absorbing plate 408 provides a quiet use environment by absorbing and reducing the noise generated by friction.

[0027] In the embodiment of the present invention, a first through-groove 101 is provided at the bottom of the first aluminum alloy plate 1, and the rotating shaft mechanism 4 is placed in the first through-groove 101, and the number of the rotating shaft mechanisms 4 is two. A second through-groove 201 is provided in the middle of the second aluminum alloy plate 2, and the second through-groove 201 is nested outside the first through-groove 101 at the bottom of the first aluminum alloy plate 1. The first through-groove 101 is provided at the bottom of the first aluminum alloy plate 1 for accommodating the rotating shaft mechanism 4. This design embeds the rotating shaft mechanism 4 in the first aluminum alloy plate 1. On the one hand, it can make the overall structure more compact and reduce the occupied space; on the other hand, the aluminum alloy plate can provide certain protection for the rotating shaft mechanism 4 to prevent it from being subjected to external impact or damage. It also provides a more stable installation environment for the hinge mechanism 4. The second through slot 201 cooperates with the first through slot 101, so that the hinge mechanism 4 can be more firmly fixed between the two aluminum alloy plates. The provision of two hinge mechanisms 4 can improve the stability and load-bearing capacity of the entire elliptical main axis. During use, the two hinge mechanisms 4 can share the weight of the keyboard and iPad as well as the pressure generated during operation, thereby reducing the burden of a single hinge mechanism 4 and extending its service life. It can also make the angle adjustment smoother and more uniform. When the user adjusts the angle of the keyboard and iPad, the two hinge mechanisms 4 can rotate synchronously to ensure the accuracy and consistency of the angle adjustment.

[0028] In the embodiment of the present invention, a limit block 402, a sleeve 403, a convex bump 406, a muffler 408 and a spring assembly 409 are nested in sequence on the left side of the surface of the shaft core 401. A limit boss 404 is fixedly arranged on one end of the sleeve 403, and a groove 405 is provided on the other end of the sleeve 403. A self-locking boss 407 is fixedly installed on one end of the convex bump 406. The limit boss 404 is matched with the limit block 402, and the self-locking boss 407 is matched with the groove 405. The other end of the shaft core 401 is interference fit with the first aluminum alloy plate 1. During use, the user applies external force to make the keyboard and iPad rotate around the shaft core 401. The shaft core 401 is effectively The keyboard and iPad are prevented from shaking or loosening during use by the user through the multiple limiting and self-locking structures, and the cooperation of the convex block 406, the shaft sleeve 403 and the shrapnel assembly 409 enables the shaft to provide resistance or lock at a specific angle, thereby achieving accurate angle adjustment and meeting the different usage requirements of users.

[0029] In the embodiment of the present invention, the torsion spring fixed shaft A501 and the rotating shaft on one side are interference connected, and the torsion spring 502 is connected between the torsion spring fixed shaft A501 and the torsion spring fixed shaft B503. The interference connection is a connection method that uses the elastic deformation of the material to tightly combine two components. In this case, the torsion spring fixed shaft A501 and the rotating shaft on one side are interference connected, which can ensure the firmness and stability of the connection. When the rotating shaft rotates, the torsion spring fixed shaft A501 can move with the rotating shaft, thereby driving the torsion spring 502 to generate torque. The advantage of this connection method is that the connection is reliable, not easy to loosen, and can withstand a certain torque and external force. At the same time, the interference connection does not require No additional connectors are required, which simplifies the structural design and reduces costs. When the user adjusts the angle between the Magic Keyboard and the iPad, the hinge rotates, driving the torsion spring fixed axis A501 to move together. The torsion spring 502 is compressed or stretched between the torsion spring fixed axis A501 and the torsion spring fixed axis B503, generating torque. This torque will act on the hinge, causing the hinge to tend to automatically reset. When the user releases the external force, the torque of the torsion spring 502 will prompt the hinge to return to its initial position, realizing the automatic reset function. If the user needs to keep the keyboard and iPad at a specific angle, the torque of the torsion spring 502 can provide a certain resistance to keep the hinge stable at that angle.

[0030] Working principle: The user applies external force to rotate the keyboard or iPad around the elliptical main axis. At this time, the shaft core 401 begins to rotate with the cooperation of the shaft sleeve 403 and other components. At the same time, the torsion spring mechanism 5 generates corresponding torque according to the angle of rotation. As the shaft core 401 rotates, the limit block 402, shaft sleeve 403, convex bump 406, silencer 408 and spring assembly 409 work together to ensure the stability of rotation and the accuracy of angle adjustment. The two shaft mechanisms 4 rotate synchronously, making the angle adjustment more stable and uniform, and sharing the load of the keyboard and iPad. d's weight and the pressure generated during operation. When the user adjusts the keyboard and iPad to the desired angle, the external force is stopped. At this time, the torque of the torsion spring mechanism 5 and the self-locking function of the self-locking boss 407 and the groove 405 keep the keyboard and iPad at this angle. If the user wants the keyboard and iPad to reset automatically, when the external force is released, the torque of the torsion spring 502 will prompt the shaft to return to the initial position. The torsion spring fixed axis A501 drives the torsion spring 502 to generate reverse torque as the shaft moves, thereby realizing the automatic reset function.
