[0047] See also Figures 1 to 3 In an embodiment of the control structure 100 proposed in the present invention, the control structure 100 includes: a rotating disk 10 and an infrared component 30. The outer edge of the rotating disk 10 is provided with a blocking member 13, and the blocking member 13 rotates with the rotating disk 10 to form a rotating path; the infrared component 30 includes an infrared emitting head 31 and an infrared receiving head 33. The infrared emitting head 31 and the infrared receiving head 33 are arranged opposite to each other and are respectively located on both sides of the rotating path.

[0048] Among them, the arrangement direction of the infrared emitting head 31 and the infrared receiving head 33 can be set parallel to the rotation plane of the rotating disk 10. At this time, the infrared emitting head 31 and the infrared receiving head 33 are respectively located on the inside and outside of the rotation path of the barrier 13 of the rotating disk 10. In addition, the arrangement direction of the infrared emitting head 31 and the infrared receiving head 33 can also be set vertically to the rotating disk 10; for example, the rotating disk 10 is placed horizontally, and the infrared emitting head 31 and the infrared receiving head 33 are respectively located above and below the rotating disk 10, and are respectively located above and below the barrier 13 on the outer wall of the rotating disk 10 (the barrier 13 at this time is similar to the setting form of the teeth in the gear). Of course, the arrangement direction of the infrared emitting head 31 and the infrared receiving head 33 and the positional relationship of the rotating disk 10 can also be set in other reasonable and effective ways according to actual conditions, which will not be repeated here.

[0049] It can be understood that this embodiment proposes a control structure 100, when used to adjust parameters (such as volume, etc.) in an electronic device 1000, the rotating disk 10 can be rotated in different rotation directions, and the blocking effect of the blocking member 13 on the infrared path of the infrared component 30 is utilized to obtain data such as the rotation direction, rotation angle, and the number of times the blocking member 13 passes through the infrared component 10 of the rotating disk 10, so as to use these data to quickly adjust the parameters (such as volume, etc.) in the electronic device 1000. In this way, the control method of mechanical buttons in the related art is replaced, the inconvenience caused by mechanical buttons is avoided, and the convenience of adjusting parameters (such as volume, etc.) on the electronic device 1000 can be improved.

[0050] Taking the volume control of the electronic device 1000 as an example, the specific process of controlling the volume using the above control structure 100 includes at least the following methods:

[0051] (1) The infrared component 30 can be used to identify whether the rotating disk 10 rotates clockwise or counterclockwise, so the clockwise rotation and counterclockwise rotation of the rotating disk 10 can be set to increase the volume and decrease the volume respectively. It can be understood that the barrier 13 has at least two ways to pass through the infrared light emitted by the infrared emitting head 31, see Fig.10 , where the circle is a cross-sectional schematic diagram of infrared rays, and the shaded portion is the portion of the infrared rays blocked by the barrier 13. It can be understood that when the barrier 13 passes through the infrared rays in different directions, the distribution of the shadows in the circle diagram is different. Fig.10 Take the case where the middle barrier 13 passes through the infrared ray as an example. When the barrier 13 passes through the infrared ray emitted by the infrared emitting head 31 from the left, the circular diagram shows the left shadow. When the barrier 13 passes through the infrared ray emitted by the infrared emitting head 31 from the right, the circular diagram shows the right shadow. The left shadow and the right shadow respectively represent: the infrared receiving head 33 does not receive the infrared signal on the left and the infrared receiving head 33 does not receive the infrared signal on the right. In this way, it can be distinguished whether the barrier 13 passes through the infrared ray from the left or the right, so as to judge whether the rotating disk 10 rotates clockwise or counterclockwise, and then control the parameters of the electronic device 1000 such as the increase or decrease of the volume, just as rotating the rotating disk 10 clockwise increases the volume, and rotating the rotating disk 10 counterclockwise decreases the volume.

[0052] (2) When the rotating disk 10 is rotated, the control structure 100 uses the infrared component 30 to obtain the number of times the blocking member 13 passes through the infrared component 30. Since each time the blocking member 13 blocks infrared rays, it corresponds to a certain angle of rotation of the rotating disk 10. Therefore, by multiplying the obtained number of times and the angle corresponding to the rotation of one blocking member 13, the angle of rotation of the rotating disk 10 at this time can be calculated, and the volume of the corresponding value can be increased or decreased.

[0053] (3) Whenever the blocking member 13 passes through the infrared component 30, the control structure 100 can recognize this action using the infrared component 30, and at this time, the electronic device 1000 can increase or decrease a preset volume value.

[0054] See also Figures 1 to 3 In an embodiment of the control structure 100 proposed in the present invention, the arrangement direction of the infrared emitting head 31 and the infrared receiving head 33 is set parallel to the rotation plane of the rotating disk 10; the infrared emitting head 31 and the infrared receiving head 33 are respectively located on the side of the rotating path facing the rotation center of the rotating disk 10 and the side of the rotating path away from the rotation center of the rotating disk 10.

[0055] It can be understood that the arrangement of the infrared emitting head 31, the infrared receiving head 33 and the rotating disk 10 can relatively reduce the volume of the control structure 100. Furthermore, the infrared emitting head 31, the infrared receiving head 33 and the rotating disk 10 can be arranged on the same straight line. Among them, the number of barriers 13 can be determined according to the size of the rotation path, and the size of the rotation path can be determined according to the size of the rotating disk 10: when the rotating disk 10 is small, only one barrier 13 can be set on the outer edge of the rotating disk 10. At this time, it takes less time to rotate the rotating disk 10 for one circle, and one barrier 13 can meet the demand of adjustment and control to a certain extent. When the rotating disk 10 is large, a plurality of barrier 13 arranged at intervals can be set on the outer edge of the rotating disk 10. At this time, it takes a long time to rotate the rotating disk 10 for one circle, and a plurality of barrier 13 need to be arranged in sequence along the circumference of the rotating disk 10 to improve the interaction efficiency with the infrared component 30, thereby meeting the demand of adjustment and control. Furthermore, the infrared emitting head 31 and the infrared receiving head 33 are respectively located at the inner side and the outer side of the rotating path. The infrared emitting head 31 and the infrared receiving head 33 may also be respectively located at the outer side and the inner side of the rotating path. Both settings are acceptable.

[0056] It should be noted that the blocking member 13 rotates with the rotating disk 10 to form an annular rotating path; therefore, the inner side of the rotating path refers to the area surrounded by the annular rotating path, that is, the side of the rotating path facing the rotation center of the rotating disk 10; the outer side of the rotating path refers to the area outside the area surrounded by the annular rotating path, that is, the side of the rotating path away from the rotation center of the rotating disk 10.

[0057] See also Figures 2 to 4 In an embodiment of the control structure 100 proposed by the present invention, the control structure 100 further includes a disk rack 50, and the rotating disk 10 is covered on the disk rack 50 and is rotatable relative to the disk rack 50;

[0058] A mounting groove 59 is formed on the surface of the disk rack 50 facing away from the rotating disk 10. The mounting groove 59 penetrates the outer wall of the disk rack 50 and forms a through opening.

[0059] One of the infrared emitting head 31 and the infrared receiving head 33 is accommodated in the installation groove 59 and is arranged toward the through opening; the other of the infrared emitting head 31 and the infrared receiving head 33 is arranged on the outer side of the blocking member 13 and is arranged toward the through opening.

[0060] Among them, the disk rack 50 can be provided with a limiter, and the limiter limits the rotating disk 10 to rotate on the disk rack 50, and the shape of the disk rack 50 is adapted to the rotating disk 10, so that the rotating disk 10 can be better covered on the disk rack 50. Further, the volume of the rotating disk 10 can be set to be slightly larger than the volume of the disk rack 50, so that the rotating disk 10 can be sleeved on the disk rack 50. Further, the disk rack 50 can be a rotating shaft component, and the rotating disk 10 is fixed on the rotating shaft component. When the rotating shaft component is rotated, the rotating disk 10 can be driven to rotate. That is, the disk rack 50 only needs to be able to support the rotating disk 10 and enable it to rotate. It can be understood that the disk rack 50 is provided to support the rotating disk 10 so that the rotating disk 10 can rotate more stably.

[0061] Among them, the surface of the rack 50 facing away from the rotating disk 10 is provided with a mounting groove 59, which is reserved for placing the infrared receiving head 33 or a space for the infrared receiving head 33. Placing the mounting position of the infrared receiving head 33 within the volume of the rack 50 can well reduce the space volume required by the control structure 100. Furthermore, there are two pairs of infrared components 30, and the two pairs of infrared components 30 are placed at a certain angle to the center of the rack 50, such as 120 degrees, 180 degrees, etc. The waveforms generated by two or more pairs of infrared components 30 are integrated and processed by the processor, which can reduce the occurrence of instruction errors and improve the accuracy of control.

[0062] See also Figure 1 and Figure 4 In an embodiment of the control structure 100 proposed in the present invention, the rotating disk 10 includes a substrate 15 and a blocking member 13. The blocking member 13 is protruded from the surface of the substrate 15 facing the disk rack 50 and is located at the outer edge of the substrate 15. A plurality of blocking members 13 are provided, and the plurality of blocking members 13 are spaced apart along the outer edge of the substrate 15.

[0063] The substrate 15 may be in the shape of a disk. Since disk-shaped objects are more stable when rotating than objects of other shapes, the disk-shaped substrate 15 is conducive to the user to rotate the rotating disk 10 more easily, which is ergonomic. Of course, the substrate 15 may be in various shapes to meet the various differentiated needs of users. Furthermore, a limiting structure may be provided on the blocking member 13 to prevent the rotating disk 10 from shaking easily and to allow the rotating disk 10 to rotate around the disk frame 50. It can be understood that the provision of a plurality of blocking members 13 can improve the sensitivity of the infrared component 30 in detecting rotation changes, thereby improving the sensitivity of the control structure 100.

[0064] See also Figures 2 to 4 In an embodiment of the control structure 100 proposed in the present invention, a first limit block 131 is protrudingly provided on the inner surface of at least one barrier member 13, and the first limit block 131 is spaced apart from the substrate 15 to form a first holding space; a first annular platform 53 is protrudingly provided on the outer wall of the disk rack 50, and the first annular platform 53 is arranged around the circumference of the disk rack 50, and the first annular platform 53 is at least partially inserted into the first holding space in the circumferential direction.

[0065] In this embodiment, three first limit blocks 131 are provided, and the three first limit blocks 131 can not only cooperate well with the disk rack 50 to ensure the rotation stability of the rotating disk 10, but also relatively save the cost of manufacturing the rotating disk 10, thereby achieving the optimal solution of the design. Further, the material of the rotating disk 10 and the disk rack 50 can be TPEE, which has excellent chemical resistance and fatigue resistance, is light in weight, and has an excellent hand feel.

[0066] See also Figures 2 to 4 In an embodiment of the control structure 100 proposed in the present invention, the rotating disk 10 also includes an inner wall 11, which is protruding from the surface of the substrate 15 facing the disk rack 50 and is located at the inner edge of the substrate 15; the inner wall 11 is arranged around the inner edge of the substrate 15, and a second limit block 111 is protruding from the surface of the inner wall 11 facing the blocking member 13, and the second limit block 111 is spaced apart from the substrate 15 to form a second clamping space; a second annular platform 57 is protruding from the inner side wall of the disk rack 50, and the second annular platform 57 is arranged around the circumference of the disk rack 50, and the second annular platform 57 is at least partially inserted into the second clamping space in the circumferential direction.

[0067] In this embodiment, the second limit blocks 111 are also provided with three, and the three second limit blocks 111 are evenly distributed on the surface of the inner wall 11 facing the barrier 13, that is, the angle between every two second limit blocks 111 and the rotation center of the rotating disk 10 is 120 degrees, and the three second limit blocks 111 can not only cooperate well with the disk rack 50 to ensure the rotation stability of the rotating disk 10, but also relatively save the cost of manufacturing the rotating disk 10, thereby achieving the optimal solution of the design. Furthermore, the surface of the rotating disk 10 away from the disk rack 50 is provided with anti-skid patterns. Among them, the anti-skid patterns can be convexly provided on the top surface of the rotating disk 10, or they can be concavely provided on the rotating disk 10, and the anti-skid patterns can also be various shapes, not limited to the shape of this embodiment, and their main function is to increase the friction during rotation and improve the user's convenience of operation.

[0068] See also Figures 2 to 5 In an embodiment of the control structure 100 proposed in the present invention, the surface of the substrate 15 facing the disk rack 50 is provided with an annular rib 151 or an annular groove 51, and the surface of the disk rack 50 facing the substrate 15 is correspondingly provided with an annular groove 51 or annular rib 151; the annular rib 151 and the annular groove 51 are both arranged around the circumference of the disk rack 50, and the annular rib 151 is accommodated in the annular groove 51. Among them, the surface of the substrate 15 facing the disk rack 50 is provided with an annular rib 151, and the surface of the disk rack 50 facing the substrate 15 is provided with an annular groove 51, and the cooperation between the annular rib 151 and the annular groove 51 can reduce the unstable rotation of the rotating disk 10. Among them, the middle part of the rotating disk 10 is hollowed out, which can reduce the weight of the rotating disk 10, facilitate rotation, and save the cost of manufacturing the rotating disk 10.

[0069] In addition, it should be noted that the control structure 100 further includes a mounting plate 90, and a clamping column is provided on the bottom surface of the disk rack 50, and the clamping column is clamped on the mounting plate 90. Among them, there are three clamping columns, and the disk rack 50 can be stably mounted on the mounting plate 90 by using the triangle stability principle. Obviously, the number of clamping columns is not limited to three, as long as the disk rack 50 can be stably mounted on the mounting plate 90. Of course, the disk rack 50 can also be mounted and fixed on the mounting plate 90 by other means such as screw connection.

[0070] See also Figure 6 In an embodiment of the control structure 100 proposed by the present invention, the control structure 100 further includes a plurality of rolling members 70, which are arranged between the rotating disk 10 and the disk rack 50. The rolling members 70 may be cylinders, spheres, etc. In this embodiment, a sphere is used, which has a simple and reliable structure. It can be understood that the configuration of the rolling members 70 can reduce the friction between the rotating disk 10 and the disk rack 50, which is more conducive to the operation of rotating the rotating disk 10 and improves the convenience of operation.

[0071] Furthermore, in order to improve the stability and reliability of the rolling element 70 when cooperating with the rotating disk 10, a plurality of receiving grooves 55 are provided on the surface of the disk frame 50 facing the rotating disk 10, and each rolling element 70 is received in a receiving groove 55. The groove wall of the receiving groove 55 is designed to be in a shape matching the sphere, so as to further improve the stability of the sphere when rotating.

[0072] See also Figure 7 The present invention further provides an electronic device 1000, which includes the control structure 100 as described above. Since the electronic device 1000 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0073] In this embodiment, the electronic device 1000 is a stereo. Of course, it is understandable that the electronic device 1000 can also be other devices, such as a display, a television, a remote controller, a refrigerator, a microwave oven, etc.

[0074] See also Figure 8 The present invention also provides a control method of an electronic device 1000, comprising the following steps:

[0075] Step S10, using the infrared component 30 to identify the moving direction of the blocking member 13 on the outer edge of the rotating disk 10, so as to obtain the corresponding rotation direction of the rotating disk 10;

[0076] Step S20 , controlling the parameters of the electronic device 1000 according to the rotation direction and the rotation amplitude of the rotating disk 10 .

[0077] It can be understood that the barrier 13 has at least two ways of passing the infrared light emitted by the infrared emitting head 31, see Fig.10 , where the circle is a cross-sectional schematic diagram of infrared rays, and the shaded portion is the portion of the infrared rays blocked by the barrier 13. It can be understood that when the barrier 13 passes through the infrared rays in different directions, the distribution of the shadows in the circle diagram is different. Fig.10Take the case where the middle barrier 13 passes through the infrared ray as an example. When the barrier 13 passes through the infrared ray emitted by the infrared emitting head 31 from the left, the circular diagram shows the left shadow. When the barrier 13 passes through the infrared ray emitted by the infrared emitting head 31 from the right, the circular diagram shows the right shadow. The left shadow and the right shadow respectively represent: the infrared receiving head 33 does not receive the infrared signal on the left and the infrared receiving head 33 does not receive the infrared signal on the right. In this way, it can be distinguished whether the barrier 13 passes through the infrared ray from the left or the right, so as to judge whether the rotating disk 10 rotates clockwise or counterclockwise, and then control the parameters of the electronic device 1000 such as the increase or decrease of the volume, just as rotating the rotating disk 10 clockwise increases the volume, and rotating the rotating disk 10 counterclockwise decreases the volume.

[0078] It should be noted that the greater the rotation amplitude of the rotating disk 10 (for example, the greater the rotation angle), the greater the adjustment amount of the parameter adjustment; the smaller the rotation amplitude of the rotating disk 10 (for example, the smaller the rotation angle), the smaller the adjustment amount of the parameter adjustment. In addition to the rotation angle, the calibration of the rotation amplitude can also be the number of times the barrier 13 passes through the infrared component 30 below or other effective and reasonable methods.

[0079] See also Fig. 9 The present invention further provides a control method for an electronic device 1000. The steps of controlling the parameters of the electronic device 1000 according to the rotation direction and the rotation amplitude of the rotating disk 10 include:

[0080] Step S21, during the rotation of the rotating disk 10, obtaining the number of times the blocking member 13 passes through the infrared component 30;

[0081] Step S22, determining the adjustment measure of the parameter according to the acquired number of times;

[0082] Step S23, according to the rotation direction of the rotating disk 10 and the adjustment scale of the parameter, the control parameter is increased or decreased.

[0083] Among them, when the number of times the blocking member 13 passes through the infrared component 30 is obtained, the control structure 100 can be configured to collect the number of times obtained each time, and perform addition operations on the collected number of times, and only when the rotating disk 10 stops rotating, the calculation result is output, and only when the rotating disk 10 stops rotating, the adjustment amount of the parameter is determined and the parameter adjustment is performed. The control structure 100 can also be configured to output the result every time the blocking member 13 passes through the infrared component 30, so as to adjust the parameter according to the preset adjustment amount corresponding to one "passing", and directly stop rotating. The above two modes can be configured on the control structure 100 at the same time for the user to choose.

[0084] In addition, it should be noted that in order to prevent accidental touch operations, a delay can be set when the rotating disk 10 starts to rotate. For example, when the rotating disk 10 starts to rotate, the number of times the blocking member 13 passes through the infrared component 30 is not collected immediately, but the number is accumulated first, and only when the number reaches a certain number, the accumulated number is collected to prevent the user from accidentally rotating the rotating disk 10.

[0085] It can be understood that this embodiment chooses to determine the adjustment amount of the parameter based on the number of times the blocking member 13 passes through the infrared component 30, and then adjusts the parameter. Since the number of times the blocking member 13 passes through the infrared component 30 is easy to identify and obtain, the adjustment process can be simpler, more reliable, and more accurate.

[0086] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
