Smart terminal

Abstract

This application relates to a smart terminal, including a rotating ring and a detection component. The rotating ring is rotatably disposed on the outer periphery of a camera decorative component, and the rotating ring has several hovering angles relative to the camera decorative component. The detection component is positioned and connected to a back cover. When the rotating ring is at different hovering angles relative to the camera decorative component, the detection component has corresponding electrical states. For any two adjacent hovering angles, the hovering angle lies between the two adjacent hovering angles. After rotating towards one adjacent hovering angle, the change in the electrical state of the rotating ring differs from the change in the electrical state after rotating towards another adjacent hovering angle. This avoids the need for thumb-based swiping touch operations on the smart terminal screen, thus preventing the risk of the smart terminal falling from the user's hand. In addition, the arrangement of the rotating ring and the detection component allows users to control the smart terminal more accurately and conveniently.

Description

Technical Field

[0001] This application relates to the field of intelligent product technology, and in particular to an intelligent terminal. Background Technology

[0002] For smartphones and other smart devices, users typically control the device via touchscreen. In parameter adjustment operations, users can slide their fingers across the screen to change parameters in response to the movement of their fingers. For example, when a camera app is open, sliding a finger across a designated area can adjust the camera module's focus.

[0003] However, when holding and operating a smart device with one hand, the thumb can only slide a small distance on the screen at a time due to the limited screen size. Otherwise, if the thumb moves too much, the smart device may fall off the user's hand. Utility Model Content

In parameter adjustment operations, the processing unit can adjust the parameter settings accordingly based on the rotation direction and range of the ring. This avoids the need for thumb-based sliding touch operations on the smart terminal screen, thus preventing the smart terminal from slipping out of the user's hand.

[0013] In one embodiment, the detection assembly further includes an insulating contact; the insulating contact abuts between a first conductive contact in one detection assembly and a second conductive contact in another detection assembly.

Detailed Implementation

[0034] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, integral connections, mechanical connections, electrical connections, direct connections, indirect connections via an intermediate medium, or internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0038] Combination Figure 1 As shown, this application provides a smart terminal 100. Exemplarily, the smart terminal 100 is a mobile phone, a PDA that can be held in one hand, or a flat-screen computer.

[0039] Specifically, the smart terminal 100 includes a body, a screen connected to the front side of the body, a camera module 20 connected to the back side of the body, and a back cover 30 connected to the back side of the body. The back cover 30 is provided with a camera decorative component 31, which covers the camera module 20, serves a decorative purpose on the back cover 30, and also provides protection for the camera module 20.

[0040] Specifically, the smart terminal 100 also includes a processing unit housed in the device body.

[0041] Combination Figure 1 and Figure 2As shown, the smart terminal 100 also includes a rotating ring 40 and a detection component 50. The rotating ring 40 is rotatably disposed on the outer periphery of the camera decorative component 31, and the rotating ring 40 has several hovering angles relative to the camera decorative component 31. The detection component 50 is positioned and connected to the back cover 30. When the rotating ring 40 is at different hovering angles relative to the camera decorative component 31, the detection component 50 has corresponding electrical states. For any two adjacent hovering angles, the hovering angle lies between the two adjacent hovering angles. After rotating towards one of the adjacent hovering angles, the change in the electrical state of the rotating ring 40 is different from the change in the electrical state of the rotating ring 40 after rotating towards the other adjacent hovering angle.

[0042] The smart terminal 100 of this application allows for free movement of the index or middle finger when held in one hand. By undulating the finger, the rotating ring 40 can rotate relative to the camera decorative assembly 31 at different hovering angles. Since the electrical state of the detection component 50 changes differently when the rotating ring 40 rotates relative to the camera decorative assembly 31 in different directions, the processing unit of the smart terminal 100 can determine the rotation direction and the range of the hovering angle change of the rotating ring 40 based on the characteristics of the electrical state change. In parameter adjustment operations, the processing unit can adjust the parameter settings accordingly based on the rotation direction and range of the rotating ring 40. This avoids the need for thumb swiping on the screen of the smart terminal 100, thus preventing the smart terminal 100 from slipping from the user's hand.

[0043] Optionally, the detection component 50 can detect the rotation of the rotating ring 40 to enable the selection and switching of various lenses in the camera module 20.

[0044] Optionally, the detection component 50 detects the rotation of the rotating ring 40, enabling parameter adjustment in the professional mode of the camera function.

[0045] Optionally, the detection component 50 can also detect the rotation of the rotating ring 40, and can also be used for operations such as web browsing, document reading, and video switching.

[0046] Optionally, the detection component 50 can detect the rotation of the rotating ring 40, which can also be used for track switching or fast forwarding in a music player, or to customize sound effects.

[0047] Optionally, the rotation detection of the rotating ring 40 by the detection component 50 can also be used for quick function activation in the screen-off state, such as quickly opening the camera or turning on the flashlight. In other embodiments, the rotation detection of the rotating ring 40 by the detection component 50 supports custom functions defined by other users.

[0048] Understandably, in addition to reducing the risk of the smart terminal 100 falling off the user's hand, the rotating ring 40 has several hovering angles relative to the camera decoration assembly 31 within one rotation range, and there is no limit to the number of rotations of the rotating ring 40 relative to the camera decoration assembly 31 in any direction, thus improving the accuracy in parameter adjustment operations.

[0049] For example, in traditional technology, zoom adjustment for camera functions typically involves displaying an adjustment area on the screen with a slider. The user moves the slider within this area using their finger to adjust the focal length. When the slider reaches one edge of the adjustment area, the focal length is adjusted to its minimum; when it reaches the other edge, it's adjusted to its maximum. However, due to screen size limitations, the width of the adjustment area is finite, resulting in a relatively dense distribution of focal length values, making precise control of the focal length using touchscreens difficult.

[0050] In this application, the hovering angle of the rotating ring 40 can be made to correspond one-to-one with the specific focal length value. Since the number of rotations of the rotating ring 40 is not limited, the focal length value can be precisely controlled within a large focal length range.

[0051] Understandably, the rotating ring 40 increases the interaction methods between the user and the smart terminal 100, allowing the user to operate the smart terminal 100 more conveniently. On the one hand, when the user needs to operate the smart terminal 100, there is no need to unlock the screen first; the user can directly use the rotating ring 40 to quickly activate pre-set functions. On the other hand, when operating with one hand, for some trigger areas on the screen that the thumb cannot directly touch, rotating the ring 40 replaces touching those trigger areas, thus allowing the user to maintain the habit of one-handed operation and avoiding the need to use the other hand to operate trigger areas that are inaccessible with one hand.

[0052] In some implementations, combined Figure 2 As shown, the detection component 50 is disposed on the inner circumference of the rotating ring 40, so that the detection component 50 and the rotating ring 40 are distributed along a plane that is perpendicular to the thickness of the body. This helps to reduce the space occupied by the detection component 50 and the rotating ring 40 along the thickness of the body and avoids affecting the thickness of the smart terminal 100.

[0053] In some other embodiments, the detection component 50 and the rotating ring 40 may be arranged opposite each other along the thickness direction of the machine body.

[0054] Optionally, combined Figure 2As shown, the rear cover 30 is connected to a guide rail structure 32, which defines the rotation axis of the rotating ring 40. Exemplarily, the guide rail structure 32 is made of metal. Exemplarily, the guide rail structure 32 defines the position of the rotating ring 40 from either the inner or outer circumferential side.

[0055] In some implementations, combined Figure 2 As shown, the smart terminal 100 also includes a rolling contact 60 movably connected to the back cover 30. An elastic structure 70 abuts against the rolling contact 60 and the back cover 30. The rotating ring 40 is provided with a plurality of positioning grooves 44, which are distributed circumferentially along the rotating ring 40. When the rotating ring 40 is at a hovering angle, the rolling contact 60 is at least partially accommodated in the positioning groove 44 under the elastic force of the elastic structure 70. Understandably, when the rotating ring 40 tends to rotate relative to the camera decorative assembly 31 under the action of an external force, the side surface of the positioning groove 44 abuts against the rolling contact 60, causing the rolling contact 60 to move in the direction of exiting the positioning groove 44, and causing compression of the elastic structure 70. Therefore, when it is necessary to move the rotating ring 40 away from the hovering angle, it is necessary to overcome the elastic force of the elastic structure 70, so that the rotating ring 40 can be stabilized at the hovering angle.

[0056] Exemplarily, the positioning groove 44 is recessed relative to the inner circumferential surface of the rotating ring 40, and the rolling contact 60 is disposed on the inner circumferential side of the rotating ring 40, forming a laterally distributed structure between the rolling contact 60 and the rotating ring 40. The rolling contact 60 is radially disposed between the elastic structure 70 and the rotating ring 40. When the rotating ring 40 is at a hovering angle, the rolling contact 60 and the positioning groove 44 are radially opposite each other, which facilitates control of the thickness of the smart terminal 100. Exemplarily, the movement path of the rolling contact 60 is defined between the camera decorative assembly 31 and other structures of the back cover 30, and this movement path is radially disposed along the camera decorative assembly 31.

[0057] For example, the positioning grooves 44 are evenly distributed along the inner circumferential surface of the rotating ring 40.

[0058] For example, combined Figure 3 As shown, when the vertical space of the smart terminal 100 is ample, the positioning groove 44 is recessed relative to the rotating ring 40 along the thickness direction of the body. The rotating ring 40 and the rolling contact 60 are opposite each other along the thickness direction of the body, that is, the rolling contact 60 is located between the rotating ring 40 and the body, forming a vertically distributed structure between the rolling contact 60 and the rotating ring 40. The rolling contact 60 is positioned between the elastic structure 70 and the rotating ring 40 along the thickness direction of the body. Understandably, when the smart terminal 100 is a low-end mobile phone or a rugged phone, the vertical space is relatively ample.

[0059] Understandably, the predetermined number of hovering angles corresponds to the number of positioning slots 44. For example, the predetermined number of hovering angles is consistent with the number of positioning slots 44.

[0060] Optionally, a plurality of rolling contacts 60 are evenly distributed along the outer periphery of the camera trim assembly 31 to provide support for the rotating ring 40 from different angles. Exemplarily, the number of rolling contacts 60 is eight, and the interval between any two adjacent rolling contacts 60 is 45°. In other embodiments, other numbers of rolling contacts 60 may be used.

[0061] Understandably, the specific number of positioning grooves 44 determines how frequently the rotating ring 40 will stop due to resistance during rotation. The magnitude of the rotational resistance experienced by the rotating ring 40 is determined by the elastic force of the elastic structure 70, the depth of the positioning grooves 44, and the chamfer radius of the sidewalls of the positioning grooves 44. Understandably, if the rotational resistance is large, it can prevent the rotating ring 40 from rotating erroneously and triggering, eliminating the need for additional locking structures for the rotating ring 40.

[0062] Optionally, the rolling contact 60 is a ball. In other embodiments, the rolling contact 60 may also be a cylindrical or disc-shaped structure.

[0063] Optionally, the elastic structure 70 may be a compression spring, a sheet spring, or other structure capable of generating elastic force on the rolling contact 60.

[0064] Alternatively, the resilient structure 70 may be a separate, detachable component. Exemplarily, a receiving space for the resilient structure 70 is defined between the camera trim assembly 31 and other structures of the rear cover 30, and one end of the resilient structure 70 is abutted. Understandably, the other end of the resilient structure 70 abuts against the rolling contact 60.

[0065] In some other embodiments, the elastic structure 70 is an integrally connected structure with the back cover 30 or the camera trim assembly 31.

[0066] In some implementations, combined Figure 3 As shown, the smart terminal 100 also includes a sealing member 80. The sealing member 80 is disposed on the outer periphery of the camera decorative assembly 31 and on the inner periphery of the rotating ring 40. Understandably, the sealing member 80 can fill the gap between the camera decorative assembly 31 and the rotating ring 40, preventing liquid or dust from entering the interior of the smart terminal 100 through this gap. Exemplarily, the sealing member 80 is ring-shaped.

[0067] Optionally, when the rotating ring 40 is at the hovering angle, the rolling contact 60 and the groove are positioned opposite each other along the thickness direction of the machine body. The seal 80 is located on the side of the rotating ring 40 closest to the machine body. The seal 80 is located on the outer periphery of all rolling contacts 60, thereby facilitating the assembly of the seal 80.

[0068] Optionally, the seal 80 and the rolling contact 60 are disposed opposite each other along the thickness direction of the machine body. For example, the seal 80 is disposed on the side of the rolling contact 60 facing away from the machine body.

[0069] In some implementations, combined Figure 2 As shown, the detection assembly 50 includes a Hall sensor 51. The rotating ring 40 has a plurality of first trigger portions 41, a plurality of second trigger portions 42, and a plurality of third trigger portions 43. The first trigger portions 41 and the third trigger portions 43 are each magnetic, and the magnetic directions of the first trigger portions 41 and the third trigger portions 43 are opposite. The first trigger portions 41, the second trigger portions 42, and the third trigger portions 43 are sequentially distributed circumferentially along the rotating ring 40. When the rotating ring 40 is at a hovering angle, one of the first trigger portions 41, the second trigger portions 42, and the third trigger portions 43 is positioned opposite to the Hall sensor 51.

[0070] For example, the first trigger part 41 and the third trigger part 43 of the rotating ring 40 are respectively formed of magnetic material.

[0071] For example, when the rotating ring 40 is at the hovering angle, one of the first trigger part 41, the second trigger part 42 and the third trigger part 43 is arranged radially opposite to the Hall sensor 51.

[0072] In some other embodiments, when the rotating ring 40 is at a hovering angle, the first trigger 41, the second trigger 42, or the third trigger 43 may be opposite to the Hall sensor 51 along the thickness direction of the fuselage.

[0073] For example, at one hovering angle, the rotating ring 40 is positioned with the second trigger 42 opposite the Hall sensor 51. After rotating counterclockwise from that hovering angle to an adjacent hovering angle, the first trigger 41 is opposite the Hall sensor 51. After rotating clockwise from that hovering angle to another adjacent hovering angle, the third trigger 43 is opposite the Hall sensor 51.

[0074] For example, combined Figure 2As shown, when the first trigger unit 41 is opposite to the Hall sensor 51, the first trigger unit 41 is aligned with the Hall sensor 51 with its P magnetic pole. The Hall sensor 51 is triggered by the P magnetic pole and turns on, outputting a positive voltage. More specifically, when the first trigger unit 41 is directly aligned with the Hall sensor 51 with its P magnetic pole, the positive voltage has its maximum absolute value. As the P magnetic pole gradually moves away from the Hall sensor 51, the absolute value of the positive voltage gradually decreases.

[0075] For example, when the third trigger unit 43 is opposite to the Hall sensor 51, the third trigger unit 43 is aligned with the Hall sensor 51 with its N magnetic pole. The Hall sensor 51 is triggered by the N magnetic pole and turns on, outputting a negative voltage. More specifically, when the third trigger unit 43 is directly aligned with the Hall sensor 51 with its N magnetic pole, the negative voltage has its maximum absolute value. As the N magnetic pole gradually moves away from the Hall sensor 51, the absolute value of the negative voltage gradually decreases.

[0076] For example, the second trigger part 42 is not magnetic, or the magnetism of the second trigger part 42 is weaker than that of the first trigger part 41 or the third trigger part 43. Therefore, when the second trigger part 42 is opposite to the Hall sensor 51, the Hall sensor 51 is in the off state and the output voltage of the Hall sensor 51 is zero.

[0077] For example, the rotating ring 40 has 24 hovering angles. The rotation angle of the rotating ring 40 between two adjacent hovering angles is 15°. The number of the first trigger part 41, the second trigger part 42, and the third trigger part 43 are 8 each.

[0078] In other embodiments, the first trigger 41, the second trigger 42, and the third trigger 43 may be of other quantities.

[0079] For example, combined Figure 4a As shown, when the rotating ring 40 is facing the Hall sensor 51 with the second trigger part 42, after the rotating ring 40 rotates counterclockwise by 15°, the first trigger part 41 faces the Hall sensor 51 with the P magnetic pole, and the output of the Hall sensor 51 transitions from zero to a positive voltage with the largest absolute value.

[0080] For example, combined Figure 4b As shown, when the rotating ring 40 is facing the Hall sensor 51 with the first trigger part 41, after the rotating ring 40 rotates counterclockwise by 15°, the third trigger part 43 faces the Hall sensor 51 with the N magnetic pole, and the output of the Hall sensor 51 transitions from the positive voltage with the largest absolute value to the negative voltage with the largest absolute value.

[0081] For example, combined Figure 4cAs shown, when the rotating ring 40 is facing the Hall sensor 51 with the third trigger 43 facing it, when the rotating ring 40 rotates counterclockwise by 15°, the second trigger 42 faces the Hall sensor 51, and the output of the Hall sensor 51 transitions from the negative voltage with the largest absolute value to zero.

[0082] For example, combined Figure 4d As shown, when the rotating ring 40 is facing the Hall sensor 51 with the second trigger part 42, after the rotating ring 40 rotates 15° clockwise, the third trigger part 43 faces the Hall sensor 51 with the N magnetic pole, and the output of the Hall sensor 51 transitions from zero to the negative voltage with the largest absolute value.

[0083] For example, combined Figure 4e As shown, when the rotating ring 40 is facing the Hall sensor 51 with the third trigger part 43, after the rotating ring 40 rotates 15° clockwise, the first trigger part 41 faces the Hall sensor 51 with the P magnetic pole, and the output of the Hall sensor 51 transitions from the negative voltage with the largest absolute value to the positive voltage with the largest absolute value.

[0084] For example, combined Figure 4f As shown, when the rotating ring 40 is facing the Hall sensor 51 with the first trigger part 41 facing it, after the rotating ring 40 rotates 15° clockwise, the second trigger part 42 faces the Hall sensor 51, and the output of the Hall sensor 51 transitions from the positive voltage with the largest absolute value to zero.

[0085] Specifically, the clockwise and counterclockwise directions mentioned above are the rotation directions observed when facing the back cover 30.

[0086] As can be seen from the above process, starting from any hovering angle, the Hall sensor 51 can output different voltage states after rotating in different directions, thus distinguishing the rotation direction of the rotating ring 40. For example, the output terminal of the Hall sensor 51 is electrically connected to the processing unit. The processing unit can determine the rotation amplitude of the rotating ring 40 by combining the output change records of the Hall sensor 51, and determine the adjustment range of the corresponding parameters.

[0087] Understandably, combined Figure 2 As shown, the number of Hall sensors 51 can be one, which helps to reduce the space occupied by the detection component 50 and reduce the hardware cost of the detection component 50.

[0088] In other embodiments, the number of Hall sensors 51 may be multiple.

[0089] Understandably, since the camera module 20 uses a large amount of magnetic materials and electromagnetic induction structures, there may be interference from the first trigger unit 41, the second trigger unit 42, or the third trigger unit 43. To mitigate this interference, a high-sensitivity Hall sensor 51 and a first trigger unit 41, the second trigger unit 42, or the third trigger unit 43 with low magnetic field strength can be selected. The mutual magnetic field interference generated between the first trigger unit 41, the second trigger unit 42, or the third trigger unit 43 and the camera module 20 can be used to perform calibration operations on the camera module 20.

[0090] In some embodiments, the rotating ring 40 is provided with positioning grooves 44 in the first trigger part 41, the second trigger part 42, and the third trigger part 43 respectively. When the rotating ring 40 is at the hovering angle, the first trigger part 41, the second trigger part 42, or the third trigger part 43 abuts against the rolling contact member 60.

[0091] For example, the rolling contact 60 is made of ferromagnetic material, and when the first trigger part 41 or the third trigger part 43 of the rolling contact 60 is opposite to each other, a magnetic attraction is generated between the rolling contact 60 and the first trigger part 41 or the third trigger part 43.

[0092] In some implementations, combined Figure 5 As shown, the rotating ring 40 has several resistor segments connected sequentially along the circumference. One resistor segment is circumferentially adjacent to another, while other resistor segments are circumferentially positioned between each other. The resistivity of the resistor segments increases progressively as they move from one resistor segment through others. The detection component 50 includes corresponding first conductive contact 52 and second conductive contact 53, the circumferential spacing between them corresponding to the extension arc of the resistor segments. The first conductive contact 52 and second conductive contact 53 form conductive contacts with the resistor segments. At least two detection components 50 are distributed circumferentially along the rotating ring 40.

[0093] Understandably, each of the circumferentially connected resistance segments has resistivity. For the coupled first conductive contact 52 and second conductive contact 53, both are in conductive contact with the annular structure formed by the resistance segments. The processing unit, electrically connected to the first conductive contact 52 and second conductive contact 53, can identify the resistance value between them. Since there is a difference in resistivity between adjacent resistance segments, and the resistance segments rotate with the rotating ring 40, the detected resistance value between the first conductive contact 52 and second conductive contact 53 will change when the rotating ring 40 rotates. Each detection component 50 corresponds to a different angular range on the outer periphery of the camera decorative component 31. Based on the resistance changes detected by the first conductive contact 52 and second conductive contact 53 in each detection component 50, the processing unit can identify the rotation direction and rotation angle of the rotating ring 40.

[0094] Understandably, there is no electromagnetic interference between the resistor segment and the camera module 20, thus avoiding the need to calibrate the camera module 20.

[0095] For example, the number of resistance segments is the same as the number of detection components 50. In the same detection component 50, the circumferential spacing between the first conductive contact 52 and the second conductive contact 53 is approximately equal to the extension arc of the resistance segment. For example, for any two adjacent detection components 50, the second conductive contact 53 of one detection component 50 and the first conductive contact 52 of the other detection component 50 are arranged close to each other but insulated from each other, so that the circumferential spacing between the conductive contact and the second conductive contact 53 is approximately equal to the extension arc of the resistance segment.

[0096] For example, combined Figure 5 As shown, the number of resistor segments and the number of detection components 50 are both three. Three equal division points are marked on the outer periphery of the camera decorative component 31, namely points A, B, and C. These three division points divide the outer periphery of the camera decorative component 31 into three arc-shaped sections: section AB, section BC, and section AC. The interval between the three division points is 120°. Correspondingly, the arc of each of the three resistor segments is approximately 120°. From the perspective of facing the back cover 30, points A, B, and C are distributed counterclockwise.

[0097] At any hovering angle of the rotating ring 40, each resistor segment corresponds to the AB, BC, or AC intervals in the circumferential direction. Any one of the AB, BC, and AC intervals can correspond to one or two resistor segments in the circumferential direction.

[0098] Understandably, the first detection component 50 is used to measure the resistance value of the resistance segment corresponding to the AB interval. The first conductive contact 52 of the first detection component 50 is located at point A, and the second conductive contact 53 of the first detection component 50 is located at point B.

[0099] The second detection component 50 is used to measure the resistance value of the resistance segment corresponding to the BC interval. The first conductive contact 52 of the second detection component 50 is located at point B, and the second conductive contact 53 is located at point C.

[0100] The third detection component 50 is used to measure the resistance value of the resistance segment corresponding to the AC interval. The first conductive contact 52 of the third detection component 50 is located at point C, and the second conductive contact 53 is located at point A.

[0101] For example, the three resistive segments are, in sequence, a first resistive segment 451, a second resistive segment 452, and a third resistive segment 453. The resistivity of the third resistive segment 453 is greater than that of the second resistive segment 452, and the resistivity of the second resistive segment 452 is greater than that of the first resistive segment 451. The arc lengths of the first resistive segment 451, the second resistive segment 452, and the third resistive segment 453 are the same. Viewed from the rear cover 30, the first resistive segment 451, the second resistive segment 452, and the third resistive segment 453 are distributed counterclockwise. Understandably, the resistivity of a resistive segment is related to the material used in that resistive segment.

[0102] Combination Figure 5 As shown, at a predetermined hovering angle, the circumferential position of the first resistor segment 451 corresponds perfectly to the AB interval, the circumferential position of the second resistor segment 452 corresponds perfectly to the BC interval, and the circumferential position of the third resistor segment 453 corresponds perfectly to the AC interval. At this time, the resistance value detected by the first detection component 50 is the smallest, the resistance value detected by the third detection component 50 is the largest, and the resistance value detected by the second detection component 50 is an intermediate value.

[0103] Combination Figure 6aAs shown, during the rotation of the rotating ring 40 clockwise by 120° from the predetermined hovering angle, the first resistance segment 451 gradually moves away from the AB interval, while the second resistance segment 452 gradually moves into the AB interval. Since the resistivity of the second resistance segment 452 is greater than that of the first resistance segment 451, the resistance value detected by the first detection component 50 gradually increases. Similarly, the second resistance segment 452 gradually moves away from the BC interval, while the third resistance segment 453 gradually moves into the BC interval, and the resistance value detected by the second detection component 50 gradually increases. Simultaneously, the third resistance segment 453 gradually moves away from the AC interval, while the first resistance segment 451 gradually moves into the AC interval. Because the difference in resistivity between the first resistance segment 451 and the third resistance segment 453 is relatively large, the resistance value detected by the third detection component 50 decreases more rapidly.

[0104] Combination Figure 6a As shown, after the rotating ring 40 rotates 120° clockwise from the predetermined hovering angle, the circumferential position of the second resistance segment 452 corresponds perfectly to the AB interval, the circumferential position of the third resistance segment 453 corresponds perfectly to the BC interval, and the circumferential position of the first resistance segment 451 corresponds perfectly to the AC interval. At this time, the resistance value detected by the third detection component 50 is the minimum, the resistance value detected by the second detection component 50 is the maximum, and the resistance value detected by the first detection component 50 is an intermediate value. Understandably, after a further 120° clockwise rotation, the circumferential position of the third resistance segment 453 corresponds perfectly to the AB interval, the circumferential position of the first resistance segment 451 corresponds perfectly to the BC interval, and the circumferential position of the second resistance segment 452 corresponds perfectly to the AC interval.

[0105] Combination Figure 6b As shown, during the process of rotating ring 40 rotating 120° counterclockwise from the predetermined hovering angle, the first resistance segment 451 gradually moves away from the AB interval, while the third resistance segment 453 gradually moves into the AB interval. Because the resistivity of the third resistance segment 453 is significantly different from that of the first resistance segment 451, the resistance value detected by the first detection component 50 increases rapidly. Simultaneously, the second resistance segment 452 gradually moves away from the BC interval, while the first resistance segment 451 gradually moves into the BC interval. Because the resistivity of the second resistance segment 452 is less than that of the first resistance segment 451, the resistance value detected by the second detection component 50 gradually decreases. At the same time, the third resistance segment 453 gradually moves away from the AC interval, while the second resistance segment 452 gradually moves into the AC interval. Because the resistivity of the second resistance segment 452 is less than that of the third resistance segment 453, the resistance value detected by the third detection component 50 gradually decreases.

[0106] Combination Figure 6bAs shown, after the rotating ring 40 rotates counterclockwise by 120° from the predetermined hovering angle, the circumferential position of the third resistance segment 453 corresponds perfectly to the AB interval, the circumferential position of the first resistance segment 451 corresponds perfectly to the BC interval, and the circumferential position of the second resistance segment 452 corresponds perfectly to the AC interval. At this time, the resistance value detected by the second detection component 50 is the minimum, the resistance value detected by the first detection component 50 is the maximum, and the resistance value detected by the third detection component 50 is an intermediate value. Understandably, after a further counterclockwise rotation of 120°, the circumferential position of the second resistance segment 452 corresponds perfectly to the AB interval, the circumferential position of the third resistance segment 453 corresponds perfectly to the BC interval, and the circumferential position of the first resistance segment 451 corresponds perfectly to the AC interval.

[0107] Optionally, the resistive segments are structures independent of the rotating ring 40, and are directly or indirectly connected to the rotating ring 40. For example, the resistive segments are resistive coatings covering the surface of the rotating ring 40. The first conductive contact 52 and the second conductive contact 53 form a longitudinally distributed structure with the rotating ring 40.

[0108] Optionally, the resistance segment is a component of the rotating ring 40, that is, the rotating ring 40 includes several resistance segments.

[0109] Optionally, the first conductive contact 52 and the second conductive contact 53 are disposed on the inner circumferential side of the rotating ring 40, and the detection assembly 50 forms a laterally distributed structure between the rotating rings 40. For example, the resistive segment is a resistive coating covering the inner circumferential surface of the rotating ring 40.

[0110] Optionally, the first conductive contact 52 and the second conductive contact 53 are respectively disposed opposite to the rotating ring 40 along the thickness direction of the housing, and the detection components 50 form a longitudinally distributed structure between the rotating rings 40. For example, one side of the rotating ring 40 faces the housing, and the resistive segment is a coating covering that side of the rotating ring 40.

[0111] Optionally, the first conductive contact 52 and the second conductive contact 53 are conductive balls, so that the first conductive contact 52 and the second conductive contact 53 can both support the rotation of the rotating ring 40 and form conductive contact with the resistive segment to realize the measurement of the resistance value. In some other embodiments, the first conductive contact 52 and the second conductive contact 53 can also be columnar or disc-shaped conductor structures.

[0112] In some embodiments, the first conductive contact 52 and the second conductive contact 53 can be used to replace the rolling contact 60 and cooperate with the positioning groove 44 to stabilize the rotating ring 40 at the hovering angle.

[0113] In some implementations, combined Figure 5As shown, the detection assembly 50 also includes an insulating contact 54. The insulating contact 54 abuts between a first conductive contact 52 in one detection assembly 50 and a second conductive contact 53 in the other detection assembly 50. Understandably, the insulating contact 54 provides rotational support for the rotating ring 40 and also acts as an insulating barrier between adjacent first conductive contacts 52 and second conductive contacts 53.

[0114] Optionally, the insulating contact 54 is made of an insulating ball bearing. Optionally, the first conductive contact 52, the second conductive contact 53, and the insulating contact 54 correspond to the elastic structure 70. Under the supporting action of the elastic structure 70, the first conductive contact 52, the second conductive contact 53, and the insulating contact 54 remain in contact with the rotating ring 40.

[0115] Optionally, the smart terminal 100 is also provided with a rolling contact 60, a first conductive contact 52, a second conductive contact 53 and an insulating contact 54.

[0116] Optionally, at the midpoint between two adjacent resistor segments, no resistive material may be provided; instead, a conductive material can be used to directly connect the two adjacent resistor segments. This midpoint may also have a positioning groove 44.

[0117] Understandably, the inner wall of the positioning groove 44 between the two ends of the resistor segment is covered with a resistive material.

[0118] In some implementations, combined Figure 7 As shown, the rotating ring 40 has a capacitive segment 56. The detection assembly 50 includes a plurality of insulating segments distributed circumferentially. One insulating segment is circumferentially adjacent to another insulating segment, and other insulating segments are circumferentially positioned between one insulating segment and another. The dielectric constant between the insulating segments increases sequentially from one insulating segment through another insulating segment to another insulating segment. When the rotating ring 40 is at a hovering angle, the capacitive segment 56 is positioned opposite to at least one insulating segment.

[0119] Understandably, several insulating segments form a ring structure.

[0120] Understandably, the capacitor segment 56 of the rotating ring 40 is made of capacitor plate material. At any hovering angle, the capacitor segment 56 of the rotating ring 40, together with one or two insulating segments, forms a capacitor structure. The insulating segments serve as the capacitor dielectric in this capacitor structure. The capacitance value of the capacitor structure is related to the dielectric constant of the dielectric material between the plates. When the rotating ring 40 rotates, the insulating segments that form the capacitor structure with the capacitor segment 56 change. Since the dielectric constant between several insulating segments increases sequentially, the capacitance value of the capacitor structure changes accordingly when the rotating ring 40 rotates. Based on the increase or decrease in capacitance value, the processing unit can identify the rotation direction of the rotating ring 40. Based on the difference in capacitance value before and after the change, the processing unit can identify the rotation angle of the rotating ring 40.

[0121] Understandably, when a fixed amount of charge is stored between the capacitor segment 56 of the rotating ring 40 and the other electrode portion of the capacitor structure, the processing unit can determine the capacitance value of the capacitor structure based on the voltage value of the capacitor structure. Each insulating segment corresponds to a conductive electrode plate, which is disposed on the side of the insulating segment opposite to the rotating ring 40, and all the electrode plates are distributed circumferentially. Since the insulating segment is located between the conductive electrode plate and the capacitor segment 56, a capacitor structure is formed among the three.

[0122] Understandably, any two adjacent conductive electrode plates are insulated from each other to prevent the charge stored on different conductive electrode plates from escaping and causing monitoring failure of the rotation direction and amplitude. Specifically, each conductive electrode plate is electrically connected to the processing unit.

[0123] For example, during the rotation of the rotating ring 40, the capacitor segment 56 forms an abutting engagement with the rolling contact 60. The rolling contact 60 is conductive, thus enabling it to be used to monitor the voltage of the capacitor structure. The rolling contact 60 maintains electrical isolation from ground.

[0124] In some implementations, combined Figure 7 As shown, the arc of capacitor segment 56 is 120°. The detection component 50 includes three circumferentially distributed insulating segments, each with an arc of 120°. Specifically, the outer periphery of the camera decorative component 31 is divided into three equal points: A, B, and C. The three circumferentially distributed insulating segments are designated as the first insulating segment 551, the second insulating segment 552, and the third insulating segment 553. The circumferential position of the first insulating segment 551 corresponds to the AB interval, the circumferential position of the second insulating segment 552 corresponds to the BC interval, and the circumferential position of the third insulating segment 553 corresponds to the AC interval. The dielectric constants of the first insulating segment 551, the second insulating segment 552, and the third insulating segment 553 decrease sequentially.

[0125] For example, there are three conductive electrode plates, which are distributed circumferentially as a first conductive electrode plate 554, a second conductive electrode plate 555, and a third conductive electrode plate 556, respectively, and correspond to the first insulating segment 551, the second insulating segment 552, and the third insulating segment 553. For example, the first conductive electrode plate 554, the second conductive electrode plate 555, and the third conductive electrode plate 556 are distributed on the inner circumference of the three insulating segments.

[0126] At any hovering angle of the rotating ring 40, the capacitor segment 56 corresponds to one or two of the AB, BC and AC intervals in the circumferential position.

[0127] Combination Figure 7 As shown, at a predetermined hovering angle, the circumferential position of capacitor segment 56 corresponds perfectly to the AB interval. Since the dielectric constant of the first insulating segment 551 is the largest, the capacitance value of the capacitor structure formed between capacitor segment 56 and detection component 50 is at its maximum value.

[0128] Combination Figure 8a As shown, during the process of rotating ring 40 rotating 120° clockwise from the predetermined hovering angle, capacitor segment 56 gradually leaves the AB interval and gradually enters the AC interval. Due to the large difference between the dielectric constant of the third insulating segment 553 and the dielectric constant of the first insulating segment 551, the capacitance value of the capacitor structure decreases rapidly.

[0129] Combination Figure 8a As shown, after the rotating ring 40 rotates 120° clockwise from the predetermined hovering angle, the capacitor segment 56 corresponds perfectly to the AC section. Since the third insulating segment 553 has the smallest dielectric constant, the capacitance value of the capacitor structure is at its minimum. Understandably, after a further 120° clockwise rotation, the capacitor segment 56 corresponds perfectly to the BC section, and the capacitance value of the capacitor structure is at an intermediate value.

[0130] Combination Figure 8b As shown, during the process of rotating ring 40 rotating 120° counterclockwise from the predetermined hovering angle, capacitor segment 56 gradually leaves the AB interval and gradually enters the BC interval. Since the dielectric constant of the second insulating segment 552 is less than that of the first insulating segment 551, the capacitance value of the capacitor structure gradually decreases.

[0131] Combination Figure 8b As shown, after the rotating ring 40 rotates counterclockwise by 120° from the predetermined hovering angle, the capacitor segment 56 corresponds perfectly to the BC interval. Since the dielectric constant of the second insulating segment 552 is in the middle, the capacitance value of the capacitor structure is in the middle value. Understandably, after a further counterclockwise rotation of 120°, the capacitor segment 56 corresponds perfectly to the AC interval, and the capacitance value of the capacitor structure is at its minimum value.

Any modifications and improvements made by those skilled in the art to the technical solutions of this application without departing from the spirit of this application should fall within the protection scope defined by the claims of this application.
