[0057] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.
[0058] Example 1
[0059] like Figure 1 As shown, this embodiment provides an electronic product 200, which can be applied to various electronic fields such as entertainment and exercise. The electronic product 200 includes an electronic body 10 and a rotary control component 100a. The rotary control component 100a is independently configured from the electronic body 10 and can be used remotely relative to the electronic body 10. The rotary control component 100a includes a control component 40, which is signal-connected to the electronic body 10.
[0060] As the actuator of the electronic product 200, the rotary control component 100a can be driven by the user to perform rotation and other actions by applying external force to the rotary control component 100a. The rotary control component 100a can record its own rotation angle and other attitude changes, and then transmit the attitude changes to the control component 40. The control component 40 processes the attitude changes and generates a control signal, which is then transmitted to the electronic body 10, which executes the corresponding instructions.
[0061] like Figures 1 to 4 As shown, this embodiment provides a rotary control component 100a for information interaction with the aforementioned electronic body 10. The rotary control component 100a includes a substrate 20, a rotating component 30, a magnetic component 50, a magnetic signal detection component 60, and a control component 40.
[0062] A rotating member 30 is rotatably connected to one side of the substrate 20. The user can drive the rotating member 30 to rotate, causing a change in its orientation. A magnetic member 50 is disposed on the rotating member 30 and generates a magnetic field. When the rotating member 30 rotates, the magnetic field generated by the magnetic member 50 changes. A magnetic signal detection member 60 is disposed on the substrate 20, located within the magnetic field of the magnetic member 50, and configured to detect changes in the magnetic field of the magnetic member 50.
[0063] The control component 40 is disposed on the substrate 20 or the rotating member 30, and the control component 40 is signal connected to the magnetic signal detection member 60 and the electronic body 10. The control component 40 is configured to receive the magnetic field change signal detected by the magnetic signal detection member 60, process the magnetic field change signal into a control signal, and the control component 40 is also configured to transmit the control signal to the electronic body 10 to control the electronic body 10 to execute corresponding instructions.
[0064] Thus, this application independently sets up the rotary control component 100a and the electronic body 10, allowing them to be used, stored, and transported separately. This not only avoids making the electronic product 200 too large but also facilitates its storage and transportation. Furthermore, the magnetic component 50 is mounted on the rotating component 30, and the magnetic signal detection component 60 is mounted on the substrate 20. When the rotating component 30 rotates relative to the substrate 20, the magnetic component 50 also rotates relative to the magnetic signal detection component 60, so that the magnetic signal detection component 60 can detect changes in the magnetic field of the magnetic component 50. Meanwhile, the control component 40 is directly mounted on the base plate 20 or the rotating component 30, enabling the rotary control component 100a to not only acquire signals but also directly process the acquired signals, thereby directly sending control signals to the electronic body 10 to control the electronic body 10 to directly execute corresponding instructions. This not only avoids setting up a relay station between the rotary control component 100a and the electronic body 10 to realize the processing of acquired signals and the transmission of control signals, but also enables the rotary control component 100a to be paired with different electronic bodies 10, improving the applicability of the rotary control component 100a.
[0065] Please combine Figures 2 to 5 In one embodiment, the substrate 20 is a circular plate or a square plate, and a mounting cavity 22 is formed in the substrate 20, and the control component 40 is housed in the mounting cavity 22.
[0066] A mounting opening 23 is provided on the side of the substrate 20 away from the rotating member 30. The mounting opening 23 communicates with the mounting cavity 22 to facilitate the placement and removal of components such as the control assembly 40 inside the mounting cavity 22. The rotary control assembly 100a also includes a mounting cover 90, which is detachably connected to the substrate 20 by fasteners such as bolts, and seals the mounting opening 23.
[0067] Furthermore, the control component 40 includes a circuit board 41, a control module 42, and a signal transmission module 43.
[0068] The circuit board 41 can be fixed to the inner wall of the mounting cavity 22 by means of adhesive bonding, bolts, screws, etc. The control module 42 and the signal transmission module 43 are mounted on the circuit board 41, and are electrically connected via wires on the circuit board 41, further enabling signal transmission between the control module 42 and the signal transmission module 43. The magnetic signal detection element 60 is wired to the circuit board 41, and is electrically connected to the control module 42 via wires, further enabling signal transmission between the control module 42 and the magnetic signal detection element 60.
[0069] The signal transmission module 43 is connected to the electronic body 10 via wireless connection technology such as Bluetooth. After the magnetic signal detector 60 detects a change in the magnetic field signal, the magnetic signal detector 60 transmits the change in the magnetic field signal to the control module 42. The control module 42 processes the change in the magnetic field signal to obtain a control signal, which is then transmitted to the electronic body 10 via the signal transmission module 43, thereby directly controlling the electronic body 10 to execute the corresponding instructions.
[0070] The magnetic signal detection element 60 is a Hall sensor. The Hall sensor's detection of magnetic field changes and the control module 42's processing of the magnetic field change signal are common methods in the prior art, and those skilled in the art can design them accordingly based on actual applications. For example, the magnetic field can be decomposed according to three mutually perpendicular X-axis, Y-axis, and Z-axis in a three-dimensional Cartesian coordinate system. The magnetic signal detection element 60 detects the changes in the magnetic field components along the X and Y axes, and the control module 42 calculates the rotation angle and direction of the rotating element 30 based on the component changes detected by the magnetic signal detection element 60. It is worth noting that the direction of the Z-axis is parallel to the direction of the rotation axis Z of the rotating element 30. Simultaneously, the control module 42 has preset control signals corresponding to the commands for each attitude change of the rotating element 30. After retrieving the corresponding control signal based on the calculated attitude change, the control module 42 transmits the control signal to the electronic body 10 through the signal transmission module 43.
[0071] Furthermore, the instructions executed by the electronic body 10 can be action instructions or display instructions. Action instructions refer to the electronic body 10 being used as an entertainment product, where the electronic screen displays characters capable of different actions, and the user controls these characters to perform corresponding actions by rotating the rotating component 30. Display instructions refer to the electronic body 10 being used as a health product, where, when the user controls the rotating component 30 to rotate, the control module 42 calculates data such as calories burned and other exercise metrics based on the rotation angle of the rotating component 30, and then controls the electronic body 10 to display the corresponding calorie value.
[0072] It is understood that, in another embodiment, the mounting cavity 22 may also be formed within the rotating member 30, thereby mounting the control component 40 within the rotating member 30. The control component 40 within the rotating member 30 can be remotely connected to the magnetic signal detection component 60 on the substrate 20 via Bluetooth or other means.
[0073] In another embodiment, the control module 42 may have at least two built-in modes, such as an entertainment mode and a health management mode, and a corresponding algorithm module may be set for each mode. When the rotary control component 100a is used in conjunction with the electronic main body 10 for entertainment, the user can select the entertainment mode built into the rotary control component 100a, so that when the user rotates the rotating part 30, the control module 42 can issue corresponding action commands. When the rotary control component 100a is used in conjunction with the electronic main body 10 for health management, the user can select the health management mode built into the rotary control component 100a, so that when the user rotates the rotating part 30, the control module 42 can issue corresponding display commands.
[0074] Thus, the rotary control component 100a of this application can preset multiple modes within the control module 42, and has preset algorithm modules corresponding to each mode. It can directly calculate the command signal in the corresponding mode based on the attitude change of the rotating component 30, thereby enabling the rotary control component 100a to work based on different usage scenarios, improving the applicability of the rotary control component 100a, and enabling it to be used with different types of products.
[0075] Please combine Figures 2 to 4In one embodiment, the rotating member 30 is rotatably connected to the top surface of the substrate 20 along the direction of gravity. The rotating member 30 can be a circular plate, a square plate, a columnar member, etc., and its specific shape can be selected according to actual design requirements. The magnetic member 50 is annular in shape, and its axis is parallel to the rotation axis Z of the rotating member 30. The magnetic member 50 has an N pole portion and an S pole portion, both of which are semi-circular in shape, so that the N pole portion and the S pole portion constitute an annular magnetic member 50.
[0076] In some implementations, the rotating member 30 can be used as a knob, and the user can rotate the rotating member 30 by hand.
[0077] In some other implementations, the rotating member 30 can be used as a rotating pedal, which can be driven to rotate by the user by foot pedal.
[0078] Please combine Figures 2 to 4 In one embodiment, the rotary control assembly 100a further includes a first bracket 70 and a second bracket 80. The first bracket 70 is detachably connected to the rotating member 30, and the magnetic member 50 is disposed on the first bracket 70. The second bracket 80 is detachably connected to the substrate 20, and the magnetic signal detection member 60 is disposed on the second bracket 80. Thus, the magnetic member 50 and the magnetic signal detection member 60 can be quickly disassembled and assembled by assembling and disassembling the first bracket 70 and the second bracket 80, facilitating the replacement of the magnetic member 50 and the magnetic signal detection member 60 with suitable models or sizes according to actual needs.
[0079] Furthermore, a first mounting groove 71 is formed on the side of the first bracket 70 near the substrate 20, and the extending direction of the first mounting groove 71 is parallel to the direction of the rotation axis Z. The magnetic component 50 is housed in the first mounting groove 71, and the outer peripheral surface of the magnetic component 50 abuts against the inner wall of the first mounting groove 71 to limit the magnetic component 50. The magnetic component 50 can be fixed to the first bracket 70 by means of adhesive bonding or the like.
[0080] The second bracket 80 has a second mounting groove 81 on the side near the rotating member 30, and the extension direction of the second mounting groove 81 is parallel to the direction of the rotation axis Z. The magnetic signal detection member 60 is housed in the second mounting groove 81, and the outer peripheral surface of the magnetic signal detection member 60 abuts against the inner wall of the second mounting groove 81 to limit the magnetic signal detection member 60. The magnetic signal detection member 60 can also be fixed to the second bracket 80 by means of adhesive bonding or other methods.
[0081] Please combine Figures 2 to 4In one embodiment, the rotating member 30 has a rotating groove 31 on the side near the substrate 20. The rotating groove 31 is cylindrical and extends parallel to the direction of the rotation axis Z. A second protrusion 21 protrudes from the side of the substrate 20 near the rotating member 30. The second protrusion 21 is cylindrical and fits into the rotating groove 31. The second protrusion 21 extends parallel to the direction of the rotation axis Z and is rotatably housed within the rotating groove 31. A rotating bearing may be provided between the outer peripheral surface of the second protrusion 21 and the inner peripheral surface of the rotating groove 31.
[0082] The bottom wall of the rotating groove 31 has a first retaining groove 310, the extension direction of which is parallel to the direction of the rotation axis Z. The first bracket 70 is retained in the first retaining groove 310 to limit its position. In addition, both the bottom walls of the first bracket 70 and the first retaining groove 310 can have connecting holes, so that the first bracket 70 can be fixed to the bottom wall of the first retaining groove 310 by bolts or other fasteners to prevent the first bracket 70 from shaking.
[0083] The second protrusion 21 has a second receiving groove 210 at one end near the rotating member 30. The bottom wall of the second receiving groove 210 has a second retaining groove 211. Both the second receiving groove 210 and the retaining groove 211 extend parallel to the direction of the rotation axis Z. The second bracket 80 is held within the second retaining groove 211 to limit its position. Furthermore, both the bottom walls of the second bracket 80 and the retaining groove 211 can have connecting holes, allowing the second bracket 80 to be fixed to the bottom wall of the retaining groove 211 using bolts or other fasteners, preventing the second bracket 80 from shaking.
[0084] Example 2
[0085] like Figure 6 and Figure 7 As shown, this embodiment provides a rotary control component 100b, including a substrate 20, a rotating component 30, a magnetic component 50, a magnetic signal detection component 60, a first support 70, and a second support 80.
[0086] Along the direction of gravity, the rotating member 30 is rotatably connected to the top surface of the substrate 20. A first protrusion 32 protrudes from the side of the rotating member 30 near the substrate 20, and a second protrusion 21 protrudes from the side of the substrate 20 near the rotating member 30. Both the first protrusion 32 and the second protrusion 21 are cylindrical structures, and the extending directions of both the first protrusion 32 and the second protrusion 21 are parallel to the direction of the rotation axis Z.

[0088] A first receiving groove 320 is formed at one end of the first protrusion 32 near the substrate 20, and the extending direction of the first receiving groove 320 is parallel to the direction of the rotation axis Z. A first holding groove 310 is formed on the bottom wall of the first receiving groove 320, and the first bracket 70 is held in the first holding groove 310 to limit the position of the first bracket 70.
[0089] Furthermore, the mounting cavity 22 is connected to the second receiving groove 210, and the second bracket 80 is connected to the inner wall of the mounting cavity 22 on the side near the second receiving groove 210.

In addition, the second retaining groove 211 is connected to the second receiving groove 210, and the diameter of the opening connecting the second receiving groove 210 and the second retaining groove 211 is larger than the outer diameter of the magnetic signal detection element 60, so that the magnetic signal detection element 60 is at least partially located within the second receiving groove 210, facilitating the magnetic signal detection element 60's ability to sense changes in the magnetic field of the magnetic element 50.
