Description

Technical Field

[0001] The utility model relates to the technical field of keyboard shafts, and more specifically, to an integral locking screw structure of a Magic Control keyboard shaft. 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 hinge has the following problems when in use:

[0004] (1) When a user uses a keyboard in a quiet workplace, when the keyboard is turned on, the keyboard will make noise due to direct friction of the internal structure during rotation. The noise generated by the direct friction of the internal structure is subtle but is particularly amplified in a quiet environment. It not only affects the user using the keyboard, but also disturbs other people around. In addition, the noise generated by this friction usually means that there is a large friction between the components. This continuous high-intensity friction will accelerate the wear of each component. Over time, this wear will continue to accumulate, greatly shortening the service life of each component, and thus reducing the service life of the entire keyboard;

[0005] (2) Secondly, when the keyboard and iPad are not in use, they are in a closed state. However, in this closed state, a slight collision or shaking may cause the keyboard to open accidentally during daily carrying, causing inconvenience to the user. During use, after the user adjusts the angle, slight vibrations in the surrounding environment may cause the keyboard angle to change, which not only affects the user's input efficiency, but may also cause the user to frequently adjust the keyboard angle, increasing the cumbersomeness of use.

[0006] The utility model can reduce the noise generated by friction during rotation, thereby increasing the service life of the product, and can achieve 0-degree self-locking when not in use, and can be rotated to open 70 degrees for self-locking and limiting when in use. Utility Model Content

[0007] The present invention aims to solve the technical problems raised by the above-mentioned background technology and provides an integral locking screw structure for the Magic Keyboard shaft.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an integral locking screw structure of a Magic Control keyboard shaft, comprising: a first bracket, a second bracket assembly is provided at both ends of the left and right ends of the first bracket, the second bracket assembly is threadedly connected to a connecting bracket, a first mounting groove is provided on both sides of the upper end of the first bracket, a cover plate is threadedly connected to the first mounting groove, the second bracket assembly includes a second bracket, an axis core, a torsion spring limiter, a torsion spring, and a flat gasket, and a self-locking part, a limit gasket, a spring group and a nut are respectively provided on the upper end of the connecting bracket from left to right.

[0009] A further preferred solution is that a first screw hole is provided in each of the first placement grooves, a first connecting hole is provided on the cover plate, and the cover plate is threadedly connected to the first placement groove through the first connecting hole and the first screw hole.

[0010] A further preferred solution is that a second placement groove is provided on the outer end surface of the first placement groove, a first connecting member is fixedly installed in the second placement groove, and the first connecting member is clamped between the first bracket and the second bracket assembly.

[0011] A further preferred solution: a groove is opened inside the second bracket, and the shaft core passes through the torsion spring limiter, torsion spring, flat gasket, connecting bracket, self-locking part, limit gasket, spring plate group and nut in sequence and is placed in the groove opened in the second bracket.

[0012] A further preferred solution is that the shaft core is provided with a second connecting hole, and the shaft core is threadedly connected to the first bracket by a screw passing through the second connecting hole.

[0013] A further preferred solution is that a third connecting hole is provided at the bottom of the connecting bracket, and the connecting bracket is threadedly connected to the second bracket through the third connecting hole.

[0014] A further preferred solution is that a self-locking groove is provided on the inner side surface of the connecting bracket, a self-locking boss is provided on the left end of the self-locking member, and the self-locking groove, the self-locking boss and the limiting gasket are rotatably matched.

[0015] Beneficial effects:

[0016] 1. By providing the second mounting slot and the first connecting member, relative movement between the first bracket and the second bracket assembly is inevitable during use of the Magic Keyboard. Without the first connecting member, the two components would be in direct contact, which would result in increased wear due to the high coefficient of friction. The first connecting member is sandwiched between the first bracket and the second bracket assembly. Its material generally has a low coefficient of friction, which can effectively reduce friction between the two. This not only reduces wear on the components and extends the service life of the keyboard, but also makes the keyboard operation smoother, improving the user experience. At the same time, by reducing friction, it can further reduce noise generation, providing users with a quieter usage environment.

[0017] 2. By providing a self-locking groove, a self-locking boss and a limiting gasket, when the keyboard is in the closed state (0 degrees), the self-locking boss cooperates with the self-locking groove to firmly lock the keyboard to prevent accidental opening. When the keyboard is rotated to about 70 degrees, it self-locks again to ensure the stability of the keyboard at this commonly used angle. This multi-angle self-locking function meets the user's requirements for keyboard angles in different usage scenarios, while also improving the safety of the keyboard and avoiding misoperation or damage to the device due to unstable angles. The limiting gasket plays a role in limiting the position and increasing stability during the self-locking process. It is arranged in conjunction with the self-locking groove and self-locking boss to ensure that the keyboard is accurately positioned in the self-locking state without shaking or offsetting, thereby improving the overall stability and reliability of the keyboard.

[0018] 3. In summary, the overall locking screw structure of the Magic Keyboard hinge is provided with a first bracket, a second bracket and a connecting bracket. The first bracket serves as the basis of the structure and provides a stable support platform for the entire hinge system. The second bracket assembly works closely with the first bracket to jointly build a sturdy frame. The groove opened inside the second bracket provides a placement space for the shaft core and other related components, so that the various components can be combined together in an orderly manner to form a stable hinge structure. The connecting bracket is connected to the second bracket through a thread and cooperates with multiple components on the shaft core to firmly connect the entire hinge system. The self-locking parts, limit washers, spring clip groups and nuts arranged on the upper end of the connecting bracket cooperate with each other to realize the locking and adjustment functions of the hinge structure, which not only ensures the stability of the keyboard during use, but also allows users to adjust the angle of the keyboard according to their needs, providing users with a more comfortable use experience.

[0025] The following is a combination of the appended examples of the present invention Figure 1-Figure 5 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0026] See also Figure 1-5In an embodiment of the present invention, an integral locking screw structure of a magic control keyboard shaft includes: a first bracket 1, a second bracket assembly 2 is provided at both ends of the left and right sides of the first bracket 1, the second bracket assembly 2 is internally threadedly connected to a connecting bracket 3, a first mounting groove 101 is opened on both sides of the upper end of the first bracket 1, a cover plate 105 is internally threadedly connected to the first mounting groove 101, the second bracket assembly 2 includes a second bracket 201, an axis core 202, a torsion spring limiter 204, a torsion spring 205, and a flat gasket 206, and a self-locking part 303, a limit gasket 305, a spring group 306 and a nut 307 are respectively provided on the upper end of the connecting bracket 3 from left to right, and the first mounting groove 101 is opened on both sides. A first screw hole 102 is provided, and a first connecting hole 106 is opened on the cover plate 105. The cover plate 105 is threadedly connected to the first placement groove 101 through the first connecting hole 106 and the first screw hole 102. Several connecting holes are evenly distributed on one side of the first bracket 1 and the second bracket assembly 2. The connection between the first bracket 1 and the second bracket assembly 2 is achieved through the connecting holes, so that the Magic Keyboard can be closely combined with the tablet device to provide a stable usage experience for the user. The upper end of the connecting bracket 3 is sequentially provided with a self-locking part 303, a limiting gasket 305, a spring group 306 and a nut 307 from left to right. These components work together to achieve locking and adjustment of the shaft structure. The shaft core 202 serves as the core component of rotation. Under the support of the second bracket 201, it works in conjunction with other components connected at both ends. The torsion spring 205 provides a certain amount of resistance and auxiliary force when the keyboard is opened and closed or the angle is adjusted through its elastic force. The torsion spring limiter 204 ensures that the torsion spring 205 works within a certain range to prevent it from excessive deformation or failure. The self-locking member 303 further enhances the stability of the connection to prevent the screws from loosening during use. The limiting gasket 305 and the spring group 306 adjust the rotation performance of the shaft by controlling the tightness and elasticity of the connection. When the user applies external force to open the keyboard, the shaft core 202 starts to rotate, driving the second bracket assembly 2 and the first bracket 1 connected at both ends to move. The torsion spring 20 During this process, the shaft 202 is compressed or stretched, generating an elastic force, which provides a certain resistance to the opening of the keyboard, making the opening process smoother. As the opening angle of the keyboard increases, the self-locking member 303, the limit washer 305, and the spring assembly 306 work together to limit the rotation range of the shaft to prevent damage caused by excessive opening. At the same time, the user can adjust the angle of the keyboard according to their needs. During the adjustment process, the shaft core 202 continues to rotate, and the elastic force of the torsion spring 205 will also change accordingly to adapt to different angle requirements. When the user closes the keyboard, the external force causes the shaft core 202 to rotate in the opposite direction, and the torsion spring 205 gradually returns to its original state, providing a certain auxiliary force for closing the keyboard.

[0027] In an embodiment of the present invention, a second mounting groove 103 is provided on the outer end surface of the first mounting groove 101, and a first connecting member 104 is fixedly installed in the second mounting groove 103. The first connecting member 104 is clamped between the first bracket 1 and the second bracket assembly 2. The second mounting groove 103 provided on the outer end surface of the first mounting groove 101 is a specific installation area. In this area, the first connecting member 104 is fixedly installed. The first connecting member 104 is clamped between the first bracket 1 and the second bracket assembly 2. During the use of the Magic Keyboard, relative movement will inevitably occur between the first bracket 1 and the second bracket assembly 2. If the first connecting member 104 is not present, the two components are in direct contact, which will lead to increased wear due to the large friction coefficient, and will also cause greater resistance to be felt during operation. When it is clamped between the first bracket 1 and the second bracket assembly 2, it can effectively reduce the friction between the two. This not only reduces the wear of the components and extends the service life of the keyboard, but also makes the operation of the keyboard smoother, improving the user experience. At the same time, by reducing friction, it reduces the generation of noise. It can play a role in buffering and shock absorption, making the keyboard quieter during use and providing users with a more comfortable working or entertainment environment.

[0028] In the embodiment of the present utility model, a groove is provided inside the second bracket 201, and the shaft core 202 passes through the torsion spring limiter 204, the torsion spring 205, the flat gasket 206, the connecting bracket 3, the self-locking member 303, the limit gasket 305, the spring group 306 and the nut 307 in sequence and is placed in the groove provided in the second bracket 201. The shaft core 202 is provided with a second connecting hole 203, and the shaft core 202 is threadedly connected to the first bracket 1 by passing a screw through the second connecting hole 203. A third connecting hole 302 is provided at the bottom of the connecting bracket 3, and the connecting bracket 3 is threadedly connected to the second bracket 201 through the third connecting hole 302.

[0029] The second bracket 201 serves as an important supporting component. The internal grooves provide space for the shaft core 202 and other related components. This design allows the various components to be combined in an orderly manner to form a stable shaft structure. The shaft core 202 passes through multiple components in sequence, including the torsion spring limiter 204, the torsion spring 205, the flat gasket 206, the connecting bracket 3, the self-locking component 303, the limit gasket 305, the spring group 306 and the nut 307. This through-type design ensures that the various components can work together under the action of the shaft core 202 to realize the various functions of the keyboard shaft. A third connecting hole 302 is provided at the bottom of the connecting bracket 3, which is threadedly connected to the second bracket 201 through this connecting hole. This connection method allows the connecting bracket 3 to be firmly fixed on the second bracket 201, and to work in conjunction with the shaft core 202 and other components. The connecting bracket 3 plays a role in connecting and transmitting force in the entire shaft structure. It connects the shaft core 202 with other components and bears various forces during the use of the keyboard. Through the threaded connection with the second bracket 201, the connecting bracket 3 can ensure that these forces are reasonably transmitted and dispersed, thereby improving the stability and reliability of the entire hinge structure. The shaft core 202 is the core component of the entire hinge structure. It is threadedly connected to the first bracket 1 with screws through the second connecting hole 203. This connection method enables the shaft core 202 to be firmly fixed on the first bracket 1, providing stable support for the entire hinge structure. At the same time, the rotation of the shaft core 202 can drive other components to move together, thereby realizing the opening and closing and angle adjustment of the keyboard. After passing through multiple components, the shaft core 202 is placed in the groove opened in the second bracket, which further ensures the position stability of the shaft core 202. The design of the groove can limit the movement range of the shaft core 202 to prevent it from offsetting or shaking during use.

[0030] The locking cam 305 is actuated by a spring 320 which is adapted to engage the locking cam 301 and engage with the spring 320 which is adapted to engage with the locking cam 301. The locking cam 305 is actuated by a spring 320 which is adapted to engage with the locking cam 301 and engage with the locking cam 301. To enhance stability, when the keyboard is in the closed position (i.e., at 0 degrees), the self-locking boss 304 engages with the self-locking groove 301 at a specific position, achieving a self-locking function. At this point, the keyboard is firmly locked in the closed position and will not open accidentally. When the user needs to use the keyboard, they apply external force to rotate the keyboard. During the rotation process, the self-locking boss 304 gradually disengages from the self-locking groove 301, releasing the self-locking state. As the keyboard rotates open, the shaft core drives other components to move together, achieving the keyboard opening action. When the keyboard is rotated to about 70 degrees, the self-locking boss 304 engages with the self-locking groove 301 again, achieving the self-locking function. At the same time, the limit washer 305 acts as a position limit to prevent the keyboard from excessive rotation.

[0031] Working principle: When using the keyboard, the keyboard is initially in a closed state, the self-locking boss 304 is in a mating state with the self-locking groove 301, the keyboard is firmly locked in the closed state, and the torsion spring 205 is in a natural state or a slightly compressed state. Then the user applies external force to open the keyboard, and the shaft core 202 begins to rotate, driving the second bracket assembly 2 and the first bracket 1 to move, and the first connecting member 104 is clamped between the first bracket 1 and the second bracket assembly 2, reducing friction and noise, and providing a certain buffer for the keyboard. In the process of opening the keyboard, the torsion spring 205 is compressed or stretched, generating elastic force, providing a certain resistance to the opening of the keyboard, making the opening process smoother. As the shaft core 202 rotates, the connecting bracket 3, self-locking member 303, limiting gasket 305, spring group 306 and nut 307 and other components work together, and the self-locking boss 304 gradually disengages from the self-locking boss 304. The locking groove 301 releases the self-locking state, and then the user adjusts the keyboard angle according to his or her needs. The shaft core 202 continues to rotate, and the elastic force of the torsion spring 205 changes accordingly to adapt to different angle requirements. The limiting gasket 305 and the spring group 306 adjust their own position and elasticity according to the angle to control the rotation resistance of the rotating shaft, so that the keyboard can remain stable at different angles. When the keyboard is rotated to about 70 degrees, the self-locking boss 304 cooperates with the self-locking groove 301 again to achieve the self-locking function. The limiting gasket 305 plays a role in limiting the position to prevent the keyboard from excessive rotation. When the user closes the keyboard after use, the external force causes the shaft core 202 to rotate in the opposite direction, and the torsion spring 205 gradually returns to its original state, providing a certain auxiliary force for the closing of the keyboard. The self-locking boss 304 cooperates with the self-locking groove 301 again to return to the locked position of the keyboard closed state.
