Abstract
Description
Technical Field
[0001] This application relates to the field of non-contact sensing technology, and more particularly to a multi-directional input device, a control handle, and a control device. Background Technology
[0002] Multi-directional input devices are widely used in control applications such as game controllers. These devices include joysticks, which allow for flexible operation in the X and Y directions, enabling precise directional control, similar to that of a game controller. Currently, multi-directional input devices primarily use a carbon film layer as the sensor to detect changes in the joystick's direction. However, carbon films have a short lifespan and are easily affected by environmental factors. After prolonged use, the carbon layer may experience voltage shifts, leading to unstable sensor output signals and impacting the overall performance of the device. Especially in high-temperature and high-humidity environments, the resistance of the carbon film may become abnormal, causing the device to malfunction. Furthermore, dust and other foreign matter easily accumulate on the surface of the carbon film during use. These impurities can affect the sliding contact of the terminals on the carbon film, leading to poor contact at the moving contacts, affecting signal transmission, and potentially causing input delays or misoperations, thus impacting the user experience.

[0014] The multi-directional input device provided in this application, through the sliding of an operating component, drives a first sliding component and a second sliding component to slide along a first direction and a second direction, respectively. Simultaneously, it drives a first metal plate and a second metal plate to slide as well.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0028] To further illustrate the technical means and effects adopted by this application in achieving its intended purpose, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments.
[0029] Please see Figure 1 and Figure 2 This application provides a multi-directional input device 100, including a housing 10, a circuit board 20, a first inductor assembly 30, a sliding assembly 40, an operating member 50, and a second inductor assembly 60. The first inductor assembly 30 includes a first inductor structure 31 and a first metal sheet 61 corresponding to the first inductor structure 31. The second inductor assembly 60 includes a second inductor structure 32 and a second metal sheet 62 corresponding to the second inductor structure 32. The housing 10 has a cavity 13, which is combined with... Figure 4 The housing 10 also has an opening 14 communicating with the cavity 13. The circuit board 20 is at least partially located within the cavity 13, at the bottom of the housing 10, and has a first electrical connection portion 21 and a second electrical connection portion 22. An operating member 50 is disposed within the cavity 13, with at least a portion of the operating member 50 extending from the opening 14. A first inductor structure 31 and a second inductor structure 32 are disposed on the circuit board 20, with the first inductor structure 31 electrically connected to the first electrical connection portion 21 and the second inductor structure 32 electrically connected to the second electrical connection portion 22. A sliding assembly 40 is housed within the cavity 13, and includes a first sliding member 41 and a second sliding member 42. The first sliding member 41 slides along a first direction X, and the second sliding member 42 slides along a second direction Y, which is different from the first direction X. The first metal plate 61 is disposed on the first sliding member 41 and faces the first inductor structure 31, and the second metal plate 62 is disposed on the second sliding member 42 and faces the second inductor structure 32. The operating member 50 is used to drive the first sliding member 41 and the second sliding member 42 to slide along the plane defined by the first direction X and the second direction Y, thereby driving the first metal plate 61 and the second metal plate 62 to move on the corresponding first inductor structure 31 and the second inductor structure 32. The first inductor structure 31 and the second inductor structure 32 are used to sense the inductance changes generated by the movement of the first metal plate 61 and the second metal plate 62, and reflect the position changes of the operating member 50 through the inductance changes, thereby outputting the signal of the operating member 50 in the first direction X and the second direction Y.
[0030] In this application, the sliding of the operating member 50 causes the first sliding member 41 and the second sliding member 42 to slide along the first direction X and the second direction Y, and simultaneously causes the first metal piece 61 and the second metal piece 62 to slide as well. When the first metal piece 61 and the second metal piece 62 slide over the corresponding first inductor structure 31 and the second inductor structure 32, the corresponding first inductor structure 31 and the second inductor structure 32 generate inductance changes due to sensing the movement of the corresponding first metal piece 61 and the second metal piece 62, thereby obtaining the inductance values of the first inductor component 30 and the second inductor component 60. The circuit board 20 obtains the position of the first metal piece 61 and the second metal piece 62 by detecting the output signal of the inductance values of the first inductor component 30 and the second inductor component 60. Through the positional relationship between the metal pieces and the sliding member 40, the positional change of the operating member 50 is obtained, thereby realizing the detection of signal input of the operating member 50 in the first direction X and the second direction Y, and thus realizing the multi-directional input device 100 to input corresponding signals according to the user's corresponding operation of the operating member 50. The multi-directional input device 100 can detect signal input at any point in the first direction X and the second direction Y, with strong stability and high resistance to inductive vibration failure.
[0031] Furthermore, the inductor assembly designed using a combination of a metal sheet and an inductor structure in this application has a longer service life. Since the metal sheet and inductor structure are not in direct contact, this solves the problems of poor lifespan and voltage shift in the carbon layer caused by carbon film wear. It also avoids the input delay or malfunction caused by dust and foreign matter easily accumulating on the carbon layer surface, which can affect the sliding of terminals on the carbon film. This fundamentally improves the user experience. Simultaneously, the combination of the metal sheet and inductor structure also solves the problem of magnets in Hall effect sensors or TMR joysticks being susceptible to magnetic interference from external magnetic components. Moreover, the design of the metal sheet and inductor structure in this application eliminates the need for magnetic shielding components required for Hall effect sensors or TMR joysticks, thus avoiding the influence of magnetic fields. The combination of the metal sheet and inductor structure also fundamentally improves output accuracy and anti-interference capability.
[0032] In some embodiments, a first metal sheet 61 is disposed above a first inductor structure 31, and a second metal sheet 62 is disposed above a second inductor structure 32. A gap is left between the metal sheets and the inductor structures. When the operating member 50 slides, it moves the first sliding member 41 and the second sliding member 42, and consequently, the first metal sheet 61 and the second metal sheet 62. Along a direction perpendicular to the plane defined by the first direction X and the second direction Y, the first metal sheet 61 is projected onto the first inductor structure 31, and the second metal sheet 62 is projected onto the second inductor structure 32. This expands the sliding range of the metal sheets when the first metal sheet 61 slides relative to the first inductor structure 31, and the second metal sheet 62 slides relative to the second inductor structure 32, thereby increasing the detection range of the metal sheets by the inductor structure.
[0033] In some embodiments, the inductor structure can be a spiral or other shaped coil, and depending on the type of inductor structure, it can be any one of etched PCB inductors, wire-wound inductors, multilayer chip inductors, thin-film inductors, toroidal inductors, air-core inductors, adjustable inductors, integrated inductors, and common-mode inductors.
[0034] In some embodiments, the first inductor structure 31 and the second inductor structure 32 are square in shape to ensure that the sliding direction of the metal sheet is consistent, thereby improving the range of inductance value changes detected by the inductor structure. In some embodiments, the metal sheet can be made of ferromagnetic or conductive materials (such as copper or aluminum), and different metal sheet materials can be selected to meet different operating frequencies. Furthermore, this application can also adjust the signal input characteristics by designing the number of turns, shape, core material of the inductor, and the material, shape, and size of the metal sheet in the inductor structure.
[0035] Combination Figure 3 In some embodiments, the housing 10 includes a first housing 11 and a second housing 12, with the first housing 11 located above the second housing 12, and the first housing 11 and the second housing 12 enclosing each other to form a cavity 13. An opening 14 is located on the first housing 11. The first housing 11 and the second housing 12 are detachably connected, and the first housing 11 and the second housing 12 are connected and fixed by means of snap-fit, plug-in, or magnetic attraction. A connector 15 is provided on the second housing 12, covering the bottom of the second housing 12 and extending to the sidewalls of the first housing 11 and the second housing 12. The connector 15 includes a fixing plate 151 and a connecting plate 152, with multiple connecting plates 152 provided, spaced apart around the periphery of the fixing plate 151. The connecting plates 152 have locking holes 153, and multiple locking blocks 111 are spaced apart along the circumference of the outer sidewall of the first housing 11. The locking blocks 111 are engaged in the locking holes 153 to lock the first housing 11 and the second housing 12 together. The fixing plate 151 has a roughly annular outline, allowing for a secure connection between the first housing 11 and the second housing 12 by means of equally spaced connecting plates 152. The second housing 12 also has multiple positioning holes 121, and the first housing 11 has multiple positioning posts 112 facing the second housing 12. The number of positioning posts 112 corresponds one-to-one with the number of positioning holes 121. The positioning posts 112 are fitted into the positioning holes 121, enabling rapid installation of the first housing 11 and the second housing 12.
[0036] See Figure 3 and Figure 4The circuit board 20 is disposed on the second housing 12. A portion of the circuit board 20 extends out of the housing 10 from the connection between the first housing 11 and the second housing 12 for electrical connection with other components. A first electrical connection portion 21 and a second electrical connection portion 22 are disposed on the surface of the circuit board 20 opposite to the second housing 12. The first electrical connection portion 21 and the second electrical connection portion 22 are spaced apart, and the first electrical connection portion 21 and the second electrical connection portion 22 are electrically connected to the corresponding first inductor structure 31 and the second inductor structure 32 through terminals.
[0037] In some embodiments, the second housing 12 is provided with a boss 122, and the circuit board 20 has an opening 23, through which the boss 122 protrudes. A first slider 41 and a second slider 42 are disposed on the boss 122. The first slider 41 and the second slider 42 are located above the circuit board 20. The first slider 41 and the second slider 42 are generally block-shaped structures. The first slider 41 has a first through hole 411, and the second slider 42 has a second through hole 421. The first slider 41 and the second slider 42 are stacked, with the first through hole 411 and the second through hole 421 at least partially overlapping. A portion of the operating member 50 is placed in the first through hole 411 and the second through hole 421. When the operating member 50 slides, it drives the first sliding member 41 and the second sliding member 42 to slide simultaneously, thereby causing the first metal piece 61 and the second metal piece 62 to slide in the first direction X and the second direction Y. The first inductor structure 31 and the second inductor structure 32 sense the change in inductance value caused by the movement of the first metal piece 61 and the second metal piece 62, and input the corresponding sliding amount signal of the first metal piece 61 and the second metal piece 62 through the first electrical connection part 21 and the second electrical connection part 22. Then, the corresponding signal is output from the output terminal of the circuit board 20 to determine the position of the metal piece. By fixing the positional relationship between the metal piece and the sliding component 40, the position of the operating member 50 in the first direction X and the second direction Y is determined.
[0038] In some embodiments, the surface of the first sliding member 41 facing the second housing 12 is provided with a first mounting post 412, and a first mounting hole 61 is formed on the first metal sheet 61. The first metal sheet 61 is assembled and fixed to the first mounting post 412 through the first mounting hole 611 to fix the first metal sheet 61 to the first sliding member 41. Two first mounting posts 412 are provided to improve the stability of the assembly of the first metal sheet 61. The surface of the second sliding member 42 facing the second housing 12 is provided with a second mounting post 422, and a second mounting hole 621 is formed on the second metal sheet 62. The second metal sheet 62 is fixed to the second mounting post 422 through the second mounting hole 621 to fix the second metal sheet 62 to the second sliding member 42. Two second mounting posts 422 are provided to improve the stability of the assembly of the second metal sheet 62.
[0039] See Figure 3, Figure 4 and Figure 5 In some embodiments, the multi-directional input device 100 includes a support frame 43 housed within a cavity 13. A first slider 41 and a second slider 42 are located between the support frame 43 and the second housing 12, and are slidably connected to the support frame 43. The surface of the support frame 43 facing the first slider 41 has a first protrusion 431, and the first slider 41 has a first groove 413 slidably connected to the first protrusion 431. The first protrusion 431 is disposed along a first direction X. When the operating member 50 slides, the first slider 41 slides along the first direction X through the sliding connection between the first protrusion 431 and the first groove 413. Simultaneously, the surface of the support frame 43 facing the second slider 42 has a second protrusion 432, and the second slider 42 has a second groove 423 slidably connected to the second protrusion 432. The second protrusion 432 is arranged along the second direction Y. The second slider 42 is slidably connected to the second groove 423 through the second protrusion 432. When the operating body slides, the second slider 42 can slide along the second direction Y, so that the first slider 41 and the second slider 42 can slide smoothly and steadily through the cooperation of the groove and the protrusion, thereby improving the user experience. The first slider 41 and the second slider 42 are both generally rectangular in shape. In some embodiments, the support frame 43 is generally square in shape. The support frame 43 includes a support plate 434 and a support column 435 disposed on the support plate 434 facing the second housing 12. The support plate 434 has through holes, and the operating body is accommodated in the first through hole 411 and the second through hole 421 through the through holes. The support column 435 is stably disposed on the second housing 12, and the first slider 41 and the second slider 42 slide between the second housing 12 and the support frame 43, so as to provide sliding space for the sliding of the first slider 41 and the second slider 42. In some embodiments, four support columns 435 are provided, and the four support columns 435 are located at the four corners of the support frame 43.
[0040] See Figure 3 , Figure 4 and Figure 5In some embodiments, the operating member 50 includes a spindle 51, a disk 52 connected to the spindle 51, and a connecting block 53 protruding from the disk 52. The spindle 51 is located outside the housing 10, and the connecting block 53 is disposed in the first through hole 411 and the second through hole 421. The spindle 51 extends out of the housing 10 through the opening 14. The disk 52 is located between the first housing 11 and the support frame 43 and is confined between the first housing 11 and the support frame 43 to prevent the operating member 50 from dislodging from the housing 10 when it moves. The radial length of the connecting block 53 is less than the radial length of the disk 52. Along the direction from the first housing 11 to the second housing 12, a movable hole is formed at the intersection of the first through hole 411 and the second through hole 421. The connecting block 53 is placed in the movable hole and passes through the first sliding member 41 and the second sliding member 42, so that when the operating member 50 slides, it can simultaneously drive the first sliding member 41 and the second sliding member 42 to slide along the first direction X and the second direction Y respectively, so as to drive the first metal piece 61 and the second metal piece 62 to slide along the first direction X and the second direction Y.
[0041] See Figure 2 , Figure 3 and Figure 4 The multi-directional input device 100 also includes a reset assembly 70 disposed within the cavity 13. The reset assembly 70 is located on the outer surface of the disk 52 and is used to reset the operating member 50 after it has slid. The reset assembly 70 has multiple spring pieces 71, with two connected spring pieces 71 intersecting. The multiple spring pieces 71 are distributed sequentially around the center of the disk 52 and form a ring structure. The spring pieces 71 have a C-shaped structure. Each spring piece 71 includes a fixing part 711 located in the middle region, two elastic parts 712 located at both ends of the fixing part 711, and a driving part 713 located at one end of the elastic part 712 away from the fixing part 711. The driving part 713 abuts against the periphery of the disk 52. The fixing part 711 is fixed to the support frame 43 and snapped onto the inner wall of the first housing 11. In order for the spring piece 71 to better provide elastic force to the disk 52, the driving parts 713 at both ends of the spring piece 71 can cover the periphery of the disk 52. The design of multiple C-shaped springs 71 provides good elasticity and stability for the operating element 50, effectively adapting to the movement trajectory of the disk 52 while maintaining good reset function. The fixing part 711 is fixed to the support frame 43 and the first housing 11. This simplified structure not only improves the ease of installation and maintenance of the multi-directional input device 100 but also reduces potential points of failure. Optionally, the number of springs 71 is four.
[0042] See Figure 6This application also provides a control handle 200, including a multi-directional input device 100. The user slides the operating member 50, causing the first sliding member 41 and the second sliding member 42 to slide along the first direction X and the second direction Y, and simultaneously causing the first metal plate 61 and the second metal plate 62 to slide as well. When the first metal plate 61 and the second metal plate 62 move relative to the corresponding first inductor structure 31 and the second inductor structure 32, the first inductor structure 31 and the second inductor structure 32 sense the inductance value generated by the movement of the first metal plate 61 and the second metal plate 62. The circuit board 20 obtains the position of the operating member 50 in the first direction X and the second direction Y by detecting the output signal of the inductance value of the first inductor structure 31 and the second inductor structure 32, thereby realizing that the multi-directional input device 100 realizes the input of corresponding signals according to the user's corresponding operation on the operating member 50.
[0043] See Figure 7 This application also provides a control device 1000, including the aforementioned control handle 200.
[0044] In this application, the multi-directional input device 100 can detect signal input at any point in the first direction X and the second direction Y, exhibiting strong stability and high resistance to inductive vibration failure. The structure combining the metal sheet and the inductor has a long service life. Since the metal sheet and the inductor do not contact each other, this solves the problems of poor lifespan and voltage shift in the carbon layer caused by carbon film wear. It also avoids the input delay or misoperation caused by dust and foreign matter easily appearing on the carbon layer surface, affecting the sliding of terminals on the carbon film, thus fundamentally improving the user experience. Simultaneously, the combination of the metal sheet and the inductor structure also solves the problem of Hall effect sensors or TMR joysticks containing magnets being susceptible to magnetic interference from external magnetic components. Furthermore, the design of the metal sheet and inductor structure in this application eliminates the need for magnetic shielding components required for Hall effect sensors or TMR joysticks, preventing the influence of magnetic fields. This combination of the metal sheet and the inductor structure fundamentally improves output accuracy and anti-interference capability.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
