Description

Technical Field

[0001] This invention relates to a button control device. Background Technology

[0002] Remote control of non-intelligent, non-digital, or third-party products such as air conditioners and refrigerators via a network has always been a challenge. Therefore, there is a growing demand for a remote control device that can control these existing non-intelligent, non-digital, or third-party products.

[0003] As a typical remote control device, such as a known panel-controlled robotic arm, which includes a two-dimensional or three-dimensional moving arm, it can perform movement (or rotation), positioning, and click operations. However, its movement and positioning are relatively complex. Due to the need to perform mechanical motion, it requires high precision, has complex implementation technology, and is relatively expensive.

[0006] Patent Document 1: CN212096383U Summary of the Invention

[0007] This invention is made to solve the above-mentioned technical problems. Its purpose is to provide a button control device that can control a variety of devices through a simple structure. It has a wide range of applications and can remotely control non-intelligent, non-digital or third-party products, while preventing accidental operation.

[0008] One aspect of the present invention relates to a button control device, comprising: a controller for controlling a magnetic force generating element in a pressing device to generate magnetic force when a pressing command is received; at least one pressing device having a magnetic force generating element, the pressing device using the magnetic force generated by the magnetic force generating element to press a controlled object; and a fixing device for positioning the pressing device relative to the controlled object.

[0009] According to this button control device, the controller can generate magnetic force in the magnetic force generating element of the pressing device when a pressing command is received, and use the magnetic force generated by the magnetic force generating element to press the controlled object. Therefore, pressing the controlled object can be achieved through the controller. In addition, the pressing device is positioned relative to the controlled object by a fixing device, which can reliably prevent accidental operation. Moreover, the layout of the pressing device can be adjusted only according to the position of the button of the controlled object, and it can be widely used for various controlled objects.

[0010] Ideally, the pressing device includes a housing and a coil and an iron core that serve as magnetic force generating elements. The housing houses the magnetic force generating elements, and one end of the iron core protrudes from the bottom of the housing facing the object being controlled.

[0011] According to this button control device, when the coil is energized, it generates a magnetic force. This magnetic force is concentrated in the magnetic core and then acts directly on the button being controlled through the lower surface of the iron core exposed from the outer shell. This allows for sufficient pressing force to be applied to the button, achieving reliable pressing.

[0012] In addition, the controller is used to control the magnetic force generating element to generate magnetic force when a press command is received from the cloud server.

[0013] Based on this structure, the button control device can receive pressing commands from the cloud server to achieve remote control.

[0014] Ideally, the pressing device also includes a manual operation section and a shield. The manual operation section is used to accept manual operation and includes a pressing part, a pressing rod, a force-applying component, and a switch. A groove is provided on the pressing rod, and at least one limiting component is provided in the range corresponding to the groove by penetrating the peripheral wall of the outer shell. The groove and the limiting component are configured such that when the pressing part is pressed down until the upper end face of the groove abuts against the limiting component, the lower end face of the pressing rod contacts the switch, thereby turning on the switch. The force-applying component is sandwiched between the lower end face of the pressing rod and the upper surface of the shield. After the manual operation is released, the pressing rod rises under the action of the force-applying component, releasing the contact with the switch, and the switch is turned off.

[0015] According to the button control device with this structure, the power switch can be manually operated by providing a manual operation part. In addition, by providing a slide groove and a limiting member, the contact and release between the pressing rod and the power switch can be reliably realized, and the pressing rod and pressing part can be prevented from falling off the housing.

[0016] In addition, the controller is used to control the magnetic force generating element to generate magnetic force when the on / off switch is turned on.

[0017] According to the button control device of this structure, when the controller detects that the on / off switch is turned on, it causes the magnetic force generating element to generate magnetic force, thereby pressing the controlled object.

[0018] Ideally, the fixing device is formed as a housing for housing the controlled object. The housing includes a top plate, a bottom plate, and a side plate. A perforated area is provided on the top plate, which is located at a position corresponding to the button area of ​​the controlled object. Multiple through holes are provided in the perforated area, which are used to fasten the pressing device to the top plate through fasteners, and the controlled object is fixed inside the housing.

[0019] The button control device based on this structure can fix the pressing device in the corresponding position according to the position of the button of the controlled object, and can be widely used in various controlled objects.

[0020] As another method, the fixing device includes a column, a first fixing part, a connecting rod, and a second fixing part. The column is located in an area where the pressing device can press the controlled object. One end of the connecting rod is fixed to the column through the first fixing part, and the other end of the connecting rod is fixed to the pressing device directly above the controlled object through the second fixing part. By adjusting the first fixing part, the pressing device is fixed in the height direction to a position where magnetic force can be applied to the controlled object.

[0021] Based on this button control device, control of the controlled object can be achieved through a simpler structure.

[0022] In addition, the controlled object is a remote control with a display screen, and there is also an exposed area on the top panel to expose the display screen.

[0023] The button control device based on this structure allows the control status of the controlled object to be confirmed through the exposed area.

[0024] Alternatively, the control object can be a single button.

[0025] Ideally, it also includes a shooting element, and the controller is also used to activate the shooting element to shoot the controlled object when it receives a shooting instruction from the cloud server.

[0026] According to this button control device, the camera of the capturing element can take a picture of the display screen of the controlled object and save the picture in the controller. If the controlled object does not have a display screen, the controller can activate the capturing element to capture the pressing process, or a part of the pressing process, such as the moment a button of the controlled object is pressed, upon receiving a capturing command.

[0027] In addition, it includes a magnetic sheet, which is disposed on the end face of the controlled object near the pressing device, and the magnetism of the magnetic sheet is the same as that generated by the magnetic force generating element.

[0028] The button control device based on this structure, by setting up a magnetic sheet, can better press the controlled object through magnetic force, ensuring the stability of operation. Attached Figure Description

[0066] The present invention will be further described below with reference to specific embodiments and accompanying drawings. More details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions and derivations based on actual application situations without departing from the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0067] Furthermore, in the figures, the same symbols are sometimes used to mark the same components, and repeated descriptions are sometimes omitted. Additionally, in the figures, dimensions and shapes are sometimes exaggerated to facilitate understanding of the invention. Furthermore, in the following detailed description, directional terms such as "upper," "lower," "inner," "outer," "longitudinal," and "transverse" are used for illustrative purposes and not for limitation.

[0068] (First Implementation)

[0069] First, refer to Figures 1-9 The general structure of the button control device according to the first embodiment of the present invention will be described.

[0070] like Figure 1As shown, the button control device 1 of the first embodiment of the present invention mainly includes at least one pressing device 10, a housing 20 serving as a fixing device, and a controller 30. The housing 20 is configured to fix and position the pressing device 10 relative to the remote controller 50, which is the object to be controlled, and to house the controller 30. Here, a remote controller with a display screen will be used as an example for explanation. Figure 6 This is a schematic diagram showing the controlled object of the button control device according to the first embodiment of the present invention, (a) is a top view, and (b) is a side view. Figure 6 As shown, the remote control 50, which is the object of control, is roughly rectangular in shape and includes multiple buttons 51 (in... Figure 6 (a) shows only one) and display screen 52, which is used to display the current control status of remote control 50.

[0071] As an example, the housing 20 is formed in the shape of a rectangular box, including a top plate 21, a bottom plate 22, and side plates 23. Figure 5 As shown, the top plate 21 is rectangular when viewed from above. A perforated area A1 and an exposed area A2 are provided on the top plate 21. The perforated area A1 is located at a position corresponding to the button area of ​​the remote control 50, and multiple through holes 211 are evenly distributed within the perforated area A1. Figure 5 (Only a portion of the through-hole is shown in the diagram). The exposed area A2 is used to expose the display screen 52 of the remote control 50, which is the object to be controlled. The base plate 22 is formed in a shape corresponding to the top plate 21, and the side plate 23 is used to connect the base plate 22 and the top plate 21. In addition to accommodating the object to be controlled, the housing 20 also houses a controller 30, which is fixed to the upper surface of the base plate 22, for example.

[0072] Various known methods can be used to position the controlled object relative to the housing 20. For example: using right-angled plastic sheets to block the controlled object and fixing the plastic sheets to the cover plate with bolts and nuts; or filling the gaps around the controlled object with foam plastic sheets to achieve the purpose of fixation; or placing the controlled object in a box with an opening at the top, covering the box with a cover plate, and then tightening the cover plate and the four sides of the box with screws; or using extendable bolts for positioning. Any method that can position the controlled object relative to the housing 20 is acceptable.

[0073] like Figure 2As shown, the pressing device 10 mainly includes a pressing part 11, a pressing rod 12, a housing 13, a spring 14 as a force-applying component, a tactile switch 15 as an on / off switch, an iron core (e.g., a silicon steel rod 16) and a coil 17 as a magnetic force generating element, a partition 18 as a shielding component, and a gasket 19 as a clamping component. The pressing part 11, the pressing rod 12, the spring 14, and the tactile switch 15 constitute a manual operation part. The partition 18 is used to shield the manual operation part from the influence of the magnetic force generated by the magnetic force generating element.

[0074] The outer casing 13 is made of a non-magnetic material and is formed as a bottomed cylindrical shape with an open top. The pressing part 11 is formed as a circular plate with an outer diameter approximately the same as the outer diameter of the outer casing 13. In addition, to clearly indicate the function of the button being controlled, a sticker L can be provided on the upper surface of the pressing part 11, on which the function of the corresponding button, such as on or off, is recorded. The pressing rod 12 is formed as a rod with an outer diameter approximately the same as or slightly smaller than the inner diameter of the outer casing 13, and its upper end is connected to the lower surface of the pressing part 11. Furthermore, a groove 121 is formed in the recess of the outer periphery of the pressing rod 12. A plurality of screws f1 (two shown in the figure) serving as limiting members are arranged in a range corresponding to the groove 121, penetrating the peripheral wall of the outer casing 13. The positional relationship between the groove 121 and the plurality of screws f1 is such that when the pressing part 11 is pressed down until the upper end face of the groove 121 abuts against the screws f1, the lower end face of the pressing rod 12 can contact the tactile switch 15, thereby turning on the tactile switch 15. When the button is released, the spring 14's rebound force causes the pressing rod 12 to rise and disengage from the tactile switch 15, thus disconnecting the tactile switch 15. By providing the slide groove 121 and multiple screws f1 acting as limiting elements, the contact and disengagement of the pressing rod 12 with the tactile switch 15 can be reliably achieved. Furthermore, the pressing rod 12 and the pressing part 11 are prevented from detaching from the housing 13.

[0075] A partition 18, serving as a shield, is fixed to the inner wall of the housing 13 by multiple screws (two shown in the diagram) f2. This partition 18 shields the magnetic force generated by the coil 17, which will be described later. A tactile switch 15 is mounted on the upper surface of the partition 18. A spring 14 is clamped between the lower end face of the pressing rod 12 and the upper surface of the partition 18. After manual operation is released, the pressing rod 12 is pushed upward by the elastic force of the spring 14, releasing its contact with the tactile switch 15, thus disengaging the tactile switch 15. Furthermore, a gasket 19, serving as a clamping element, is provided on the lower surface of the partition 18. The gasket 19 is used to clamp the coil 17 and the silicon steel rod 16, which are magnetic force generating elements, to prevent them from wobbling.

[0076] The upper end face of the silicon steel rod 16 is pressed together by a gasket 19, and the lower end face protrudes from a through hole 131 located at the center of the bottom of the outer casing 13, so that the magnetic force can directly act on the button of the control object below. A coil 17 is wound around the silicon steel rod 16. When the coil 17 is energized, the coil 17 generates a magnetic force, which is concentrated in the silicon steel rod 16, which serves as the magnetic core, and then acts directly on the button of the control object through the lower surface of the silicon steel rod 16 exposed from the outer casing 13. In this embodiment, a silicon steel rod 16 is shown, but its material is not limited to this; for example, it can be any material that can generate magnetic force, such as iron.

[0077] In addition, multiple mounting holes 132 are provided around the bottom of the housing 13. For example... Figure 3 As shown, the mounting hole 132 is used to cooperate with the through hole 211 provided on the cover plate 21. The pressing device 10 is fixed relative to the cover plate 21 by passing the screw f3, which serves as a fastener, through the through hole 211 and the mounting hole 132.

[0078] The following describes the tactile switch 15 and its electrical connections. Figure 4 This is a schematic diagram showing the wiring of the magnetic force generating element according to the first embodiment of the present invention. Here, a tactile switch 15 with dimensions of 6*6*5 and a stroke of 2.5mm will be used as an example for explanation. This tactile switch 15 has, for example, four solder feet, which can be fixed to the partition 18 by folding them up. Switch lines l1 and l2 are respectively spot-welded to two solder feet of the tactile switch 15. One end of the coil 17 is connected to the high-level line l3, and the other end is connected to the ground line l4. The aforementioned switch lines l1, l2, high-level line l3, and ground line 14 pass through the through hole k provided in the housing 13 and are respectively connected to the controller 30 and the grounding member G.

[0079] Figure 8 This is a schematic diagram showing the communication line of the button control device according to the first embodiment of the present invention. Figure 8 As shown, switch lines l1, l2 and high-level line l3 are connected to controller 30, and ground line l4 is connected to grounding component G. Controller 30 controls one or more pressing devices 10 in the button control device 1 based on instructions from cloud server 80. Optionally, controller 30 can also activate the shooting element 43 based on shooting instructions from cloud server 80, so that the shooting element 43 can take a picture of the display screen of remote control 50.

[0080] The structure of the button control device according to the first embodiment of the present invention has been generally described above. Next, the operation of the button control device with the above structure, i.e., the control method, will be described.

[0081] <Manual Operation>

[0082] The operator selects the pressing device 10 to be pressed as needed. When the operator manually presses the pressing part 11, the pressing rod 12 moves downward until the upper end face of the slide groove 121 abuts against the screw f1. At this time, the lower end face of the pressing rod 12 can contact the tactile switch 15, so that the switch lines l1 and l2 are connected. The controller 30 detects the connection state of the tactile switch 15, thereby determining that there is a manual pressing action by the operator, and at the same time determining the controlled object and the number of presses. The controller 30 detects this connection state as receiving a pressing command, and energizes the high-level line l3. The energizing time is, for example, 0.3-1 second, and an appropriate time can be set according to the actual situation, such as 0.5 seconds. After the coil 17 is energized, it will cause the silicon steel rod 16 to generate a strong magnetic force. This magnetic force repels the strong neodymium magnet M on the upper surface of the button 51 of the remote control 50, thereby producing a pressing action on the button 51 of the remote control 50. The controller 30 can also send a return instruction to the cloud server indicating that a manual operation has been performed. This return instruction may include, for example, the controlled object and the number of presses. In the case of manual operation, the number of presses is 1.

[0083] If the button control device 1 also includes a camera element 43, such as a camera with LEDs, a shooting command can be sent from the cloud server 80 to the controller 30 via the communication device 70. Upon receiving the shooting command, the controller 30 activates the camera and LEDs of the camera element 43 to capture a picture of the controlled object. If the controlled object 50 includes a display screen 52, the camera of the camera element 43 can be used to take a picture of the display screen 52 of the controlled object 50, and the result can be saved in the controller 30. Then, the controller 30 turns off the camera and LEDs and uploads the result to the cloud server 80. In the cloud server 80, image and text recognition is performed on the result to determine the display information of the display screen 52.

[0084] If the controlled object does not include a display screen, the controller 30 may activate the camera and LED light of the shooting element 43 to shoot the pressing process, or a part of the pressing process, such as the moment when the button 51 of the controlled object 50 is pressed, upon receiving a shooting command.

[0085] Remote Operation

[0086] The operator can send a pressing command from the cloud server 80 to the controller 30 via the communication device 70. This command may include, for example, the object to be pressed, the number of presses, etc. Upon receiving the pressing command, the controller 30 energizes the high-level line 13 of the pressing device 10 corresponding to the object to be pressed for 0.3-1 second. The energizing time can be set appropriately according to the actual situation, for example, 0.5 seconds. Similarly, when the coil 17 is energized, it generates a strong magnetic force in the silicon steel rod 16. This magnetic force repels the strong neodymium magnet M on the upper surface of the button 51 on the remote control 50, thereby pressing the button 51. When multiple presses are required, it is best to allow a specified interval, such as 0.2 seconds, between each operation to allow the pressed button 51 to reset. This is because the magnetic force generating element of the pressing device 10 will not generate magnetic force within the specified time, and the repulsive force between the silicon steel rod 16 and the strong neodymium magnet M on the upper surface of the button 51 of the remote control 50 will disappear, thus no longer generating a pressing action.

[0087] Similarly, if the button control device 1 also includes a camera element 43, such as a camera with LEDs, a shooting command can be sent from the cloud server 80 to the controller 30 via the communication device 70. Upon receiving the shooting command, the controller 30 activates the camera and LEDs of the camera element 43 to take a picture. If the controlled object 50 includes a display screen 52, the camera of the camera element 43 can be used to take a picture of the display screen 52 of the controlled object 50, and the picture result can be saved in the controller 30. Then, the controller 30 turns off the camera and LEDs and uploads the picture result to the cloud server 80. In the cloud server 80, image and text recognition is performed on the picture result to determine the display information of the display screen 52.

[0088] If the control object 50 does not include a display screen, the controller 30 may activate the camera and LED light of the shooting element 43 to shoot the pressing process, or a part of the pressing process, such as the moment when the button 51 of the control object 50 is pressed, upon receiving a shooting command.

[0089] The structure and control method of the button control device 1 according to the first embodiment of the present invention have been described above. The button control device 1 according to the above embodiment can achieve the following technical effects.

[0090] (1) It can send instructions from the cloud server to the controller of the button control device through the communication device to remotely control the controlled object, and can realize intelligent control of existing non-intelligent, non-digital or third-party products.

[0091] (2) The structure is simple. It only needs to generate magnetic force through a magnetic force generating element to realize the pressing action of the controlled object, and the pressing action can be easily released.

[0092] (3) It can be operated manually and remotely through a single device.

[0093] (4) A pressing device is set for the button of a control object to achieve reliable operation.

[0094] (5) The layout of the pressing device can be adjusted according to the position of the button of the controlled object, and it can be widely used in various controlled objects.

[0095] The above describes an example where the remote control 50 with a display screen 52 is the controlled object. In the case where the controlled object is a control panel fixed to a wall, such as the control panel of a central air conditioning system, as... Figure 9 As shown, simply provide an opening at the bottom plate 22 of the housing 20, embed the control panel C1 into the opening, and place the strong neodymium magnet M on the surface of the buttons of the control panel C1.

[0096] (Second Implementation)

[0097] Figure 10 This is a schematic diagram illustrating the button control device according to the second embodiment of the present invention and its application scenario.

[0098] The main differences between the button control device of the second embodiment of the present invention and the button control device of the first embodiment are: 1) it is applicable to control objects in the form of a single button, and 2) the structure of the fixing device. The following mainly describes the structure of the fixing device; for structures identical to those in the first embodiment, the same symbols are sometimes used, and detailed descriptions are omitted.

[0099] First, such as Figure 10 As shown, the button control device of the second embodiment of the present invention uses a single button C2 as the control object.

[0100] Secondly, the fixing device in the second embodiment mainly includes a column 41, a first fixing part 45, a connecting rod 44, and a second fixing part 46. The column 41 is located within the area where the button C2 can be pressed by the pressing device 10. One end of the connecting rod 44 is fixed to the column 41 by the first fixing part 45, and the other end of the connecting rod 44 is fixed to the pressing device 10 directly above the button C2 by the second fixing part 46. By adjusting the first fixing part 45, the pressing device 10 can be fixed in the height direction at a position where magnetic force can be applied to the button C2.

[0101] After the pressing device 10 is operated manually or remotely, the controller 30 causes the magnetic force generating element of the pressing device 10 to generate a magnetic force, which repels the strong neodymium magnet (not shown) disposed on the upper surface of the button C2, thereby generating a pressing action on the button C2.

[0102] According to the button control device of the second embodiment, control of the controlled object can be achieved through a simpler structure.

[0103] The embodiments and variations of the present invention have been described above. However, it should be understood that this disclosure is not limited to the above embodiments and structures. This disclosure also includes various variations and modifications within the equivalent scope. In addition, various combinations and methods, and further combinations and methods that include only one element or more or less thereof, also fall within the scope and spirit of this disclosure.

[0104] For example, in the embodiments described above, the simultaneous manual and remote operation is exemplified by a single pressing device 10. However, the present invention is not limited to this; when manual operation is not required, the components for manual operation can be omitted, for example... Figure 2 (a) The components above the pad 19 (pressing part 11, pressing rod 12, spring 14, tactile switch 15, partition 18). At this time, the outer casing 13 is formed as a sealed shell to house the coil 17 and silicon steel rod 16, which are magnetic force generating elements. After receiving the pressing command sent from the cloud server 80 through the communication device 70, the controller 30 energizes the high-level line 13, causing the coil 17 and silicon steel rod 16 to generate a strong magnetic force, thereby producing a pressing action on the button of the controlled object.

[0105] Furthermore, in the above embodiments, coil 17 and silicon steel rod 16 were described as examples of magnetic force generating elements, but the present invention is not limited to this, and any device capable of generating magnetic force may be used.

[0106] Furthermore, the above example illustrates a configuration where a pressing device corresponds to a single button. However, the invention is not limited to this. In cases where two or more adjacent buttons are typically pressed simultaneously, it is also possible to configure each button with a strong neodymium magnet M, and to apply pressing force to the two or more adjacent buttons simultaneously using a single pressing device.

[0107] Furthermore, if the button of the controlled object itself has magnetic force, the strong neodymium magnet M can be omitted.
