Description

Technical Field

[0001] The present invention relates to the technical field of consumer electronics, and in particular to a 3D magnetic axis key and a keyboard thereof. Background Art

[0002] With the advancement of consumer electronics, more and more users are looking beyond just daily office tasks to computer keyboards, embracing a sense of technology and convenience. Traditional mechanical keyboard switches (such as Cherry MX, optical switches, and magnetic switches) primarily rely on a switch-type triggering mechanism with a single function (press / release). However, with market demand for high-performance and personalized input, users are increasingly seeking a more refined analog input experience for games like racing and flight simulations, or an alternative input experience to a touchpad. Existing magnetic switch keyboards have limitations: discrete input: Traditional mechanical keyboards only support binary triggering (0 / 1), making continuous and gradual control impossible (e.g., character movement speed or camera rotation rate). Furthermore, they suffer from redundant and inefficient operation, with complex operations relying on multi-key combinations (e.g., "Shift+W" for sprinting), resulting in high finger load and delayed response times. Furthermore, they are rigid in their adaptability to various scenarios: the single 3D magnetic switch key function cannot flexibly respond to diverse software requirements (e.g., pressure-sensitive brushes in design software or frame-level fine-tuning in video editing), requiring frequent peripheral switching between scenarios. Summary of the Invention

[0003] The purpose of the present invention is to provide a 3D magnetic axis joystick module, which combines the continuous control capability of an analog joystick with the integrated layout of a keyboard, breaks through the discrete limitations of digital signals at the physical layer, and realizes a universal input solution of "one axis for multiple uses".

[0004] To solve the above technical problems, the present invention provides a 3D magnetic axis key, comprising a base mounted on a circuit board, a shell buckled with the base, and a press-rebound mechanism fixedly mounted inside the shell, wherein the press-rebound mechanism is fixedly connected to a keycap at one end away from the base, and a magnet is fixedly connected to the other end of the press-rebound mechanism away from the keycap. The key also includes a shaking structure mounted on the base, the shaking structure being rotatably connected to the press-rebound mechanism. And, a reset mechanism is clamped in the shell, and the reset mechanism surrounds the press-rebound mechanism.

[0005] Furthermore, the shaking structure is an arc-shaped ring, the end of the pressing rebound mechanism close to the magnet passes through the shaking structure and is rotatably connected to the inner side wall of the shaking structure in the short axis direction, and the outer side wall of the shaking structure in the long axis direction is rotatably connected to the base. Furthermore, the reset mechanism includes a first annular body slidably connected to the housing, the sliding direction of the first annular body and the housing is a vertical direction, and the first annular body is located between the housing and the press-rebound mechanism. and a first spring installed between the first annular body and the housing, wherein one end of the first annular body is fixedly abutted against the first annular body, and the other end of the first spring is abutted against the housing; And, a second annular body fixedly connected to the press-rebound mechanism, the second annular body is located on the side of the shaking structure away from the base, the second annular body is in conflict with the first annular body, and the second annular body is located on the side of the first annular body away from the keycap.

[0006] Furthermore, the contact angle between the second annular body and the first annular body is an outer chamfer of an arc, and the contact angle between the first annular body and the second annular body is an inner chamfer of an arc.

[0007] Furthermore, a circular groove is formed on the first annular body. The circular groove is located on a side of the first annular body away from the pressing and rebounding mechanism. The first spring is installed in the circular groove.

[0008] Furthermore, a plurality of limiting plates are provided on the outer side of the first circular body. The plurality of limiting plates are distributed on the outer side of the first circular body in a circular matrix and enclose the first circular body to form the circular groove.

[0009] Furthermore, the shell includes a first part that is buckled on the base and slidably connected to the first ring body, and a second part that is integrally formed with the first part. A first circular hole is provided on the second part, and the press-rebound mechanism passes through the first circular hole. The keycap is located on the side of the second part away from the magnet, and the diameter of the keycap is larger than the diameter of the first circular hole.

[0010] Furthermore, the press-rebound mechanism includes a push rod fixedly buckled with the keycap, and the magnet abuts against an end of the push rod away from the keycap; and a first isolation plate wrapping the magnet, wherein the first isolation plate is fixedly connected to the push rod and is located on the outer side of one end of the push rod close to the magnet; and a second spring abutting against an end of the push rod away from the keycap, wherein the second spring is surrounded by an outer side of the first isolation plate; And, a second isolation plate is surrounded by the second spring, the second isolation plate is integrally formed with the second ring body, and the second isolation plate is rotatably connected to the shaking structure.

[0011] Furthermore, a second circular hole is provided at the bottom of the base, and a diameter of the second circular hole is larger than a diameter of the press-rebound mechanism.

[0012] The present invention also provides a keyboard equipped with the above-mentioned 3D magnetic axis key.

[0013] Compared with the existing technology, the present invention has the following advantages: a 3D magnetic axis button realizes conventional signal input by pressing and releasing the button with the user's finger on the push-and-rebound mechanism. When a function similar to a joystick of a game controller is needed, the user rotates the push-and-rebound mechanism, and the mechanism shakes along the shaking structure. The magnet follows the movement, which is detected by the Hall effect sensor and outputs an analog signal to the chip, thus achieving multi-directional triggering, pressure grading, and dynamic response. The reset mechanism also resets the push-and-rebound mechanism, realizing automatic and repeated input of multi-frequency signals.

[0014] In addition to the two conventional press and release commands of the 3D magnetic axis key input, users can also shake the press-rebound mechanism, and the reset mechanism will reset the press-rebound mechanism after shaking. In this way, the binary trigger limitation of the traditional magnetic axis keyboard is broken, and multi-dimensional precise control is achieved. It also supports 360° direction recognition and pressure grading (such as light push to slow down, heavy push to sprint), improving the accuracy of game control (such as character movement / perspective adjustment) and design software (such as brush strength).

[0015] It has precise operation, and can replace multiple key combinations (such as WASD shift or shortcut keys) with a single finger, reducing operation delays and improving operation efficiency.

[0016] It can also be used in more scenarios, such as the physical joystick module or pressure axis customizable mapping function (such as video timeline zoom, drone control), solving the pain point of multi-tool switching. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figures 1 to 7 The present invention provides a 3D magnetic axis key 100, including a base 20 mounted on a circuit board 10, a shell 30 buckled with the base 20, and a press-rebound mechanism 40 fixedly installed inside the shell 30, wherein the end of the press-rebound mechanism 40 away from the base 20 is fixedly connected to a keycap 80, and the end of the press-rebound mechanism 40 away from the keycap 80 is fixedly connected to a magnet 50. The key also includes a shaking structure 60 mounted on the base 20, the shaking structure 60 is rotatably connected to the press-rebound mechanism 40; and a reset mechanism 70 clamped in the shell 30, the reset mechanism 70 surrounds the press-rebound mechanism 40.

[0020] In practice, the keyboard 200 is a revolutionary input device, the core of which is the ability to accurately detect and dynamically adjust the travel of each 3D magnetic axis key 100. The circuit board 10 is a PCB board, on which the MCU main control chip and the Hall sensor are integrated to process the movement signal from the magnet 50 in each 3D magnetic axis key 100. A plurality of 3D magnetic axis keys 100 are mounted on the circuit board 10, forming the mechanical input end of the keyboard. The structure of each 3D magnetic axis key 100 includes a base 20 fixedly buckled on the circuit board 10, a shell 30 fixedly buckled on the base 20, and a press-and-release mechanism 40 that realizes the conventional pressing and releasing function in the Z-axis direction. The press-and-release mechanism 40 passes through the shell 30, and the end outside the shell 30 is a cross-column design that is compatible with the mainstream keycaps 80 on the market. A magnet 50 is fixedly connected to the end of the press-and-release mechanism 40 away from the keycap 80. When the user presses the press-and-release mechanism 40, it will drive the magnet 50 inside it to move downward, and the magnet 50 will contact with the keycap fixed on the P The distance between the Hall sensors on the CB continuously changes. The Hall sensors sense the continuous changes in the magnetic field strength (and / or angle) generated by the magnet 50 and output a continuously changing analog voltage signal proportional to the current magnetic field strength (i.e., the distance between the magnets 50). The main control MCU (also soldered to the PCB) continuously reads these analog signals at high speed. Using an algorithm, the MCU converts these analog signal values ​​into the precise 100-degree travel distance of the 3D magnetic axis button (in millimeters or as a percentage of 0-100%) in real time and determines the output command based on the user's configuration (trigger point, reset point). In addition, in this embodiment, the user can shake the press-and-rebound mechanism 40 on the basis of the conventional press and release command inputs of the two conventional magnetic axis 3D magnetic axis buttons 100, and the reset mechanism 70 can be used to reset the press-and-rebound mechanism 40 after shaking. In this way, the binary trigger limitation of the traditional magnetic axis keyboard is broken through, and multi-dimensional precise control is achieved. It also supports 360° direction recognition and pressure grading (such as light push to slow down, heavy push to sprint), improves the accuracy of game control (such as character movement / perspective adjustment) and design software (such as brush strength), and has operational sophistication; and can replace multiple key combinations (such as WASD displacement or shortcut keys) with a single finger, reducing operation delays and improving operation efficiency; and can be applied to more scenarios, such as physical joystick modules or pressure axis customizable mapping functions (such as video timeline zoom, drone control), solving the pain points of multi-tool switching.

[0021] Preferably, Figure 1 、 Figure 3 and Figure 4 As described, the rocking structure 60 is an arc-shaped ring, and the end of the pressing and rebounding mechanism 40 close to the magnet 50 passes through the rocking structure 60 and is rotatably connected to the inner wall of the rocking structure 60 in the short axis direction, and the outer wall of the rocking structure 60 in the long axis direction is rotatably connected to the base 20.

[0022] In this way, the arc-shaped ring-shaped hollow structure, while ensuring that the induction of the magnet 50 and the Hall sensor fixed on the PCB board is not affected, the rotational connection between the pressing rebound mechanism 40 and the inner wall of the arc-shaped ring-shaped shaking structure 60 in the short axis direction can realize the left and right shaking of the 3D magnetic axis button 100, and the rotational connection between the outer wall of the shaking structure 60 in the long axis direction and the base 20 can realize the front and back shaking of the 3D magnetic axis button 100.

[0023] Preferably, Figure 1 and Figure 4 The reset mechanism 70 includes a first annular body 71 that is slidably connected to the shell 30, the sliding direction of the first annular body 71 and the shell 30 is a vertical direction, the first annular body 71 is located between the shell 30 and the press-rebound mechanism 40, and a first spring 72 installed between the first annular body 71 and the shell 30, one end of the first annular body is fixedly abutted against the first annular body 71, and the other end is abutted against the shell 30; and a second annular body 73 that is fixedly connected to the press-rebound mechanism 40, the second annular body 73 is located on the side of the shaking structure 60 away from the base 20, the second annular body 73 is in contact with the first annular body 71, and the second annular body 73 is located on the side of the first annular body 71 away from the keycap 80.

[0024] During implementation, a plurality of sliding grooves with vertical sliding directions are opened on the inner wall of the shell 30 , and a protrusion integrally formed on the first annular body 71 is slidably connected along the sliding grooves, and a first spring 72 is installed between the first annular body 71 and the shell 30 . When the user needs to input a command for the shaking direction freedom, the finger presses the keycap 80 and shakes the pressing and rebounding mechanism 40. The end of the pressing and rebounding mechanism 40 away from the keycap 80 shakes along the shaking structure 60, and drives the second circular body 73 integrally formed with it to shake. One side of the second circular body 73 pushes the first circular body 71 to slide upward along the inner wall of the shell 30, and the first spring 72 is also squeezed by the first circular body. When the user releases the finger, under the elastic force of the first spring 72, the first circular body 71 slides downward along the inner wall of the shell 30. The side of the first circular body 71 away from the keycap 80 presses down the raised side of the second circular body 73 until the pressing and rebounding mechanism 40 returns to the vertical state, thereby realizing the automatic reset of the physical structure of the shaking command.

[0025] Preferably, Figure 5 and Figure 6 As described above, the contact angle between the second annular body 73 and the first annular body 71 is an outer chamfer of an arc, and the contact angle between the first annular body 71 and the second annular body 73 is an inner chamfer of an arc.

[0026] In this way, when the user shakes the 3D magnetic axis button 100, the interaction between the first circular body 71 and the second circular body 73 is more smoothly transitioned, bringing a smoother 3D magnetic axis button 100 feedback experience.

[0027] Preferably, a circular groove 711 is formed on the first annular body 71 . The circular groove 711 is located on a side of the first annular body 71 away from the pressing and rebounding mechanism 40 . The first spring 72 is installed in the circular groove 711 .

[0028] In this way, when assembling and installing the case, the first spring 72 can be placed in the circular groove 711 of the first annular body 71 first, and then the first annular body 71 is inserted into the outer shell 30, which can facilitate installation and separate the first spring 72 from the vertical inner wall of the outer shell 30 to prevent the first spring 72 from being easily stuck between the first annular body 71 and the second annular body 73 when shaking the 3D magnetic axis button 100.

[0029] Preferably, a plurality of limiting plates 712 are provided on the outer side of the first annular body 71 . The plurality of limiting plates 712 are distributed in a circular matrix on the outer side of the first annular body 71 and together with the first annular body 71 form a circular groove 711 .

[0030] During implementation, the number of the limiting plates 712 is greater than two, which can achieve the limitation of the first spring 72 and reduce the material used for the first annular body 71.

[0031] Preferably, the housing 30 includes a first part 31 that is buckled onto the base 20 and slidably connected to the first ring body, and a second part 32 that is integrally formed with the first part 31. A first circular hole 33 is provided on the second part 32, and the press-rebound mechanism 40 passes through the first circular hole 33. The keycap 80 is located on the side of the second part 32 away from the magnet 50, and the diameter of the keycap 80 is larger than the diameter of the first circular hole 33.

[0032] In this way, the first part 31 of the shell 30 is fixed to the base 20 and slides with the first annular body 71, the second part 32 is abutted against the first spring 72, and the pressing rebound mechanism 40 passes through the first circular hole 33 and extends a distance, because the downward movement of the keycap 80 will be limited to the maximum distance by the second part 32, and the extended distance is the maximum depth of the 3D magnetic axis key 100.

[0033] Preferably, the press-rebound mechanism 40 includes a push rod 41 fixedly fastened to the keycap 80, the magnet 50 abuts against the end of the push rod 41 away from the keycap 80; and a first isolation plate 42 that wraps the magnet 50, the first isolation plate 42 is fixedly connected to the push rod 41, and is located on the outside of the end of the push rod 41 close to the magnet 50; and a second spring 43 abuts against the end of the push rod 41 away from the keycap 80, the second spring 43 is surrounded by the outside of the first isolation plate 42; and a second isolation plate 44 surrounded outside the second spring 43, the second isolation plate 44 is integrally formed with the second ring body, and the second isolation plate 44 is rotatably connected to the shaking structure 60.

[0034] During implementation, the end of the push rod 41 away from the base 20 is a cross column design that is compatible with the mainstream keycap 80 on the market and fixedly buckled, and the magnet 50 is pushed by the push rod 41. The first isolation plate 42 and the push rod 41 wrap the magnet 50 to limit the freedom of the magnet 50 in all directions, and a small hole is also opened at the bottom of the first isolation plate 42 to facilitate the induction between the magnet 50 and the Hall sensor. The second spring 43 is installed between the second isolation plate 44 and the first isolation plate 42 and is against the first push rod 41. When the push rod 41 is pressed down, the second spring 43 is compressed by the first push rod 41, and the push rod 41 pushes the magnet 50 on the first isolation plate 42 and the magnet 50 moves downward, and senses the Hall sensor soldered on the circuit board 10, detecting the pressing command and the stroke of the magnet 50, that is, the stroke of the 3D magnetic axis button 10. When the downward pressure of the user's finger is released, under the elastic force of the second spring 43, the push rod 41 is pushed upward by the second spring 43, and the push rod 41 is fixedly engaged with the first isolation plate 42, driving the first isolation plate 42 and the magnet 50 to move upward and reset, and senses the Hall sensor soldered on the circuit board 10, detecting the release command of the 3D magnetic axis button 100.

[0035] Preferably, a second circular hole 21 is formed at the bottom of the base 20 , and the diameter of the second circular hole 21 is larger than the diameter of the pressing and rebounding mechanism 40 .

[0036] In this way, when the push-rebound mechanism 40 is pressed up and down, the push rod 41 pushes the magnet 50 to move downward and can be sensed by the Hall sensor without any obstruction, and the material used for the base 20 is also reduced.

[0037] See also Figure 7 The embodiment of the present application also provides a keyboard 200, which is installed with a 3D magnetic axis key 100 as any one of the above items. Because the 3D magnetic axis key 100 is installed on the keyboard 200, the keyboard 200 of this embodiment includes the beneficial effects corresponding to the 3D magnetic axis key 100 as any one of the above items.
