Single self-locking Magic Keyboard Hinge

Abstract

This utility model discloses a single self-locking Magic Keyboard hinge, comprising alloy component one and alloy component two. Both ends of alloy component one are fitted with hinge assemblies, and alloy component two is respectively mounted on one end of the hinge assembly. Sealing components are installed on the ends of alloy component two furthest from alloy component one. This utility model, by installing a hinge assembly between alloy component one and alloy component two, causes a torsion spring in the hinge assembly to rotate when either alloy component one or alloy component two rotates. This provides a certain torque for the keyboard and protective case within the Magic Keyboard during rotation, and allows for self-locking at 0 degrees and 70 degrees, facilitating keyboard use at a specific angle.

Description

Technical Field

[0001] This utility model relates to the field of keyboard hinge technology, specifically a hinge for a single self-locking Magic Keyboard. Background Technology

[0002] The Magic Keyboard is used in Apple products such as iPhones and iPads. It supports the M1-MAC and features Bluetooth, Lightning, and Wi-Fi. It is a keyboard designed to assist mobile devices. When using the Magic Keyboard, it typically uses a panel to support the device for ease of use, and the panel's rotation is usually achieved through a hinge.

[0003] Currently, the Magic Keyboard consists of two parts: a protective case and a keyboard that are rotatably connected. During use, it is necessary to maintain a certain angle between the keyboard and the protective case, and to ensure that there is a certain torque when the keyboard and the protective case rotate to prevent accidental rotation. Based on this, a single self-locking Magic Keyboard hinge is proposed. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figures 1 to 4 As shown, the single self-locking Magic Keyboard hinge in this embodiment includes alloy part 1 and alloy part 2. Alloy part 1 and alloy part 2 are respectively provided with useful mounting holes for connecting alloy part 1 and alloy part 2 to the keyboard and panel. Hinges are installed at both ends of alloy part 1, and alloy part 2 is installed at one end of each hinge assembly. The hinge assembly is used to realize the rotation between alloy part 1 and alloy part 2. A sealing assembly is installed at the end of alloy part 2 away from alloy part 1. The sealing assembly is used to seal the outer end of alloy part 2 to prevent dust from entering.

[0025] The rotating shaft assembly includes a shaft core 301, a torsion spring 302, a bushing 303, a second limiting member 304, a self-locking member 305, a limiting ring 306, a spring washer 307, and a nut 308. One end of the shaft core 301 is fitted with the torsion spring 302. The bushing 303 is fitted onto the surface of the shaft core 301 on one side of the torsion spring 302. The second limiting member 304 is fitted onto the surface of the shaft core 301 on one side of the bushing 303. The self-locking member 305 is fitted onto the surface of the shaft core 301 on one side of the limiting member 304. The shaft core 301 on one side of the self-locking member 305... A limiting ring 306 is fitted onto the surface of shaft core 301. A spring washer 307 is fitted onto the surface of shaft core 301 on one side of the limiting ring 306. A nut 308 is threaded onto the surface of shaft core 301 on one side of the spring washer 307. When the shaft assembly is in the working chamber, the bushing 303 rotates. The bushing 303 rotates the torsion spring 302, so that the shaft assembly has a certain torque when it rotates. By rotating the nut 308, the nut 308 compresses the torsion spring 302 through various components, thereby adjusting the rotation torque of the shaft assembly.

[0026] Specifically, the surfaces of the shaft cores 301 on both sides of the torsion spring 302 are fitted with limiting components 5. Each limiting component 5 has a limiting through hole. The two ends of the torsion spring 302 are located inside the limiting through holes. The two limiting components 5 fix and install the torsion spring 302. The rotation of the bushing 303 drives the limiting components 5 to rotate, thereby rotating the torsion spring 302.

[0027] Furthermore, the shaft core 301 has a fixed end 3011 and a threaded end 3012 at both ends. The torsion spring 302, bushing 303, limiter 304, self-locking component 305, limit ring 306, spring washer 307 and nut 308 are respectively sleeved on the surface of the threaded end 3012. Both ends of alloy part 1 and alloy part 2 are provided with slots 6. The fixed end 3011 is located inside the slot 6 inside alloy part 1, and the bushing 303 is located inside the slot 6 inside alloy part 2. The fixed end 3011 and the slot 6 on alloy part 1 are interference-fitted, and the bushing 303 and the slot 6 on alloy part 2 are interference-fitted, so as to realize the installation of the rotating shaft assembly and realize the rotation function of alloy part 1 and alloy part 2.

[0028] Furthermore, a washer 7 is installed on the surface of the threaded end 3012 on one side of the limiting member 5, and an mounting member 8 is installed on the surface of the threaded end 3012 on one side of the washer 7. The mounting member 8 is used to install the washer 7. The washer 7 prevents the torsion spring 302 and the self-locking member 305 from making direct contact, so that the rotating assembly rotates more smoothly.

[0029] Furthermore, both ends of the bushing 303 are provided with mounting grooves. The two limiting members 5 are located inside the mounting groove on one side, while the limiting member 304, the self-locking member 305, and the limiting ring 306 are located inside the mounting groove on the other side. One end of the self-locking member 305 is provided with a self-locking groove 9, and the limiting ring 306 is provided with a self-locking boss 10. The self-locking boss 10 and the self-locking groove 9 work together. When the alloy part 2 drives the bushing 303 to rotate, the self-locking groove 9 on the self-locking member 305 contacts the self-locking boss 10, thereby achieving self-locking and limiting of the rotating shaft assembly at 0 degrees and 70 degrees.

[0030] Furthermore, the sealing assembly includes a sealing cap 401 and an O-ring 402. The surface of the sealing cap 401 is provided with an annular groove 11, and the O-ring 402 is located inside the annular groove 11. The O-ring 402 is located inside the groove 6 on the outer side of the alloy part 2. The sealing cap 401 and the O-ring 402 achieve a seal on the outer end of the alloy part 2, ensuring the overall dustproof and waterproof function of the shaft and increasing the overall aesthetics.

[0031] The usage method of this embodiment is as follows: When in use, alloy part 1 and alloy part 2 are connected to the keyboard and the panel respectively. When rotating, alloy part 2 drives the bushing 303 to rotate, and the bushing 303 drives the limiting part 5 at one end of the torsion spring 302 to rotate, so that the keyboard and the panel can be opened. At the same time, the opening torque is large and the closing torque is small. Meanwhile, the limiting ring 306 rotates on the surface of the self-locking part 305. When the self-locking boss 10 on the limiting ring 306 rotates into the self-locking groove 9 on the self-locking part 305, the 0-degree and 70-degree self-locking of the rotating shaft is achieved.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
