[0058] The embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

[0059] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application.

[0060] This application discloses a detection method, the flowchart of which is shown below. Figure 1 As shown, it includes:

[0061] Step S11: Determine the target correspondence between the rotational torque and rotation angle of the shaft structure when the shaft structure is in the target state. The target state represents the switching of the rotating component in the shaft structure based on the first shaft and the second shaft.

[0062] Step S12: Based on the target correspondence when the rotating shaft structure is in the target state, determine whether the rotating shaft structure meets the conditions.

[0063] For electronic devices that rotate two bodies via a hinge to change the angle between them, such as laptops, the hinge connecting the two bodies may experience jamming or free travel during the change of the angle.

[0064] Based on this, in this solution, the hinge structure is tested to determine whether it meets the conditions. If the hinge structure meets the conditions, it can be determined that there will be no problems such as jamming or empty travel during the rotation process, and the hinge structure that meets the conditions can be applied to electronic devices. If the hinge structure does not meet the conditions, it can be determined that there may be problems such as jamming or empty travel during the rotation process, and the hinge structure may need to be adjusted before it can be applied to electronic devices to ensure the user experience of the electronic devices.

[0065] The rotating shaft structure involved in this embodiment may include at least a first rotating shaft and a second rotating shaft, that is, both the first rotating shaft and the second rotating shaft can be rotated as rotating components, such as... Figure 2 The diagram shows a rotating shaft structure including two rotating shafts, including: a first rotating shaft 21, a second rotating shaft 22, and a connecting member 23 between the first rotating shaft 21 and the second rotating shaft 22. The first rotating shaft 21 can rotate relative to the connecting member 23, and the second rotating shaft 22 can also rotate relative to the connecting member 23.

[0066] The first rotating shaft 21 and the second rotating shaft 22 are provided with grooves. When the end of the connecting piece 23 that contacts the first rotating shaft 21 slides into the groove of the first rotating shaft 21 (e.g., Figure 2 When the first rotating shaft 21 (marked with groove 211) is rotated, the first rotating shaft 21 stops rotating, and the second rotating shaft 22 rotates instead; as the second rotating shaft 22 rotates, the end of the connector 23 that contacts the second rotating shaft 22 slides into the groove of the second rotating shaft 22 (the groove of the second rotating shaft 22 is in...). Figure 2 (not shown in the image), at this time, the second rotating shaft 22 stops rotating. If it continues to rotate, the end of the connector 23 that is in contact with the first rotating shaft 21 slides out of the groove of the first rotating shaft 21, and the rotation of the first rotating shaft 21 is switched back.

[0067] Taking the application of a hinge structure in a laptop as an example, the first hinge in the hinge structure is fixed to the first body of the laptop (such as the body where the keyboard is located), and the second hinge in the hinge structure is fixed to the second body of the laptop (such as the body where the display screen is located). When the first hinge rotates as a rotating component, the first body rotates, and when the second hinge rotates as a rotating component, the second body rotates.

[0068] Specifically, such as Figure 3 The diagram shows a schematic of the rotation of two shafts when the shaft structure, including two rotating shafts, is applied to an electronic device. Figure 3 In this context, "Bottom" represents the first axis of rotation, and "Top" represents the second axis of rotation. When the angle between the first and second bodies is 0 degrees, the rotation angle between the first and second axes is also 0 degrees, and the first and second axes appear as follows: Figure 3The effect shown in part a; as the rotating structure rotates, the first rotating shaft (Bottom) rotates first as a rotating component until it reaches the first angle (e.g., 100 degrees), as shown in part a. Figure 3 As shown in section b; when the first angle (e.g., 100 degrees) is reached, the rotating component switches from the first axis (Bottom) to the second axis (Top), and rotates from the second axis (Top) until the second angle (e.g., 280 degrees) is reached. Figure 3 As shown in section c, at this point, the end of the connector that contacts the first rotating shaft slides into the groove of the first rotating shaft, the first rotating shaft stops rotating, and the second rotating shaft begins to rotate; when the second angle is reached (e.g., 280 degrees), the rotating component switches from the second rotating shaft (Top) to the first rotating shaft (Bottom), until 360 degrees are reached, as shown. Figure 3 As shown in section d, at this time, the end of the connector that contacts the second rotating shaft slides into the groove of the second rotating shaft, and the end of the connector that contacts the first rotating shaft slides out of the groove of the first rotating shaft, and the first rotating shaft continues to rotate.

[0069] Therefore, in a shaft structure comprising two shafts, when the rotating component (first shaft or second shaft) rotates, a switching of the rotating component occurs, i.e., the rotating component switches from the first shaft to the second shaft, or vice versa. During this process, the switching of the rotating component will cause jamming or idle travel in the shaft structure. However, if the rotating component does not switch, such as when the rotating component remains the first shaft, the rotation of the shaft structure will not experience jamming or idle travel, and there is no need to determine whether the shaft structure meets the conditions at this time.

[0070] Therefore, it is necessary to inspect the rotating shaft structure when the rotating components switch to determine whether the rotating shaft structure will experience jamming or idle travel, that is, to determine whether the rotating shaft structure meets the conditions.

[0071] The switching of rotating components in the shaft structure can be characterized by the target state. When the rotating components in the shaft structure switch, it is determined that the shaft structure is in the target state. Therefore, during the rotation of the shaft structure, it is necessary to detect the shaft structure to determine whether the shaft structure is in the target state. When the shaft structure is in the target state, the target correspondence between the rotational torque and the rotation angle of the shaft structure is determined.

[0072] The rotational torque of a shaft structure refers to the torque required to cause deformation or overcome internal friction during rotation. It is a core indicator for evaluating the damping performance of a shaft and directly affects whether the shaft can stably remain at any angle. Therefore, to ensure that the shaft structure does not experience jamming or idle travel during rotation, it is necessary to ensure that the relationship between the rotational torque and the rotation angle remains constant. That is, regardless of the rotation angle, the relationship between the rotational torque and the rotation angle should be the same or similar. If the relationship between the rotational torque and the rotation angle changes significantly within a certain angle or range, it can be determined that the shaft structure does not meet the requirements at that angle or within that range. In this case, the shaft structure may experience jamming or idle travel.

[0073] For example, in a rotating shaft structure, when the rotation angle between the first and second rotating shafts is a first angle (e.g., 100 degrees), the relationship between rotational torque and rotation angle changes significantly compared to the relationship when the rotation angle is less than the first angle (e.g., less than 100 degrees). Therefore, it can be determined that when the rotation angle between the first and second rotating shafts is the first angle, the rotating shaft structure may experience jamming or idle travel. In this case, it can be determined that the rotating shaft structure does not meet the conditions.

[0074] The detection method disclosed in this embodiment determines the target correspondence between the rotational torque and rotation angle of the rotating shaft structure when it is in a target state. The target state characterizes the switching between the first and second rotating shafts of the rotating components in the rotating shaft structure. Based on the target correspondence when the rotating shaft structure is in the target state, it determines whether the rotating shaft structure meets the conditions. This solution determines that the rotating shaft structure is in a target state based on the switching between the first and second rotating shafts of the rotating components in the rotating shaft structure, and determines the target correspondence between the rotational torque and rotation angle of the rotating shaft structure when it is in the target state. Based on this, it determines whether the rotating shaft structure meets the conditions, thereby realizing the detection of the rotating shaft structure to determine whether problems such as jamming or idle travel will occur during the application of the rotating shaft structure.

[0075] This embodiment discloses a detection method, the flowchart of which is as follows: Figure 4 As shown, it includes:

[0076] Step S41: Determine the target correspondence between the rotational torque and rotation angle of the rotating shaft structure when the rotating shaft structure is in the target state. The target state represents the switching of the rotating component in the rotating shaft structure based on the first rotating shaft and the second rotating shaft.

[0077] Step S42: Based on the target correspondence when the shaft structure is in the target state, determine the rotational torque and rotational angle curve when the shaft structure is in the target state;

[0078] Step S43: By analyzing the rotational torque and rotational angle curves of the shaft structure in the target state, determine whether the shaft structure meets the conditions.

[0079] The target correspondence between the rotational torque and rotational angle of the rotating shaft structure is determined when the rotating shaft structure is in the target state. The target state represents the switching between the rotating components in the rotating shaft structure based on the first rotating shaft and the second rotating shaft. Based on the target correspondence when the rotating shaft structure is in the target state, it is determined whether the rotating shaft structure meets the conditions. This is to enable the judgment of whether the rotating shaft structure meets the conditions by using the target correspondence between the rotational torque and rotational angle of the rotating shaft structure, so as to avoid problems such as jamming or empty stroke of the rotating shaft structure during application.

[0080] When determining whether a rotating shaft structure meets the conditions based on the target correspondence when the rotating shaft structure is in the target state, the target correspondence can be specifically adjusted to the rotational torque and rotational angle curve of the rotating shaft structure. The change of the curve can clearly and directly determine whether the rotating shaft structure meets the conditions.

[0081] Specifically, the state of the rotating structure can be detected first. When the rotating shaft structure is detected to be in the target state, the target correspondence between the rotational torque and rotation angle of the rotating shaft structure is determined. That is, this target correspondence is only determined when the rotating shaft structure is in the target state. Then, based on the target correspondence when the rotating shaft structure is in the target state, the rotational torque and rotation angle curve of the rotating shaft structure in the target state is determined. That is, the determined rotational torque and rotation angle curve is only the curve corresponding to the rotating shaft structure in the target state, and does not include the data corresponding to the rotating shaft structure when it is not in the target state.

[0082] For example: In a rotating shaft structure, when the rotation angle between the first and second rotating shafts is between 70 and 120 degrees, and the rotating shaft structure is determined to be in the target state (e.g., the rotating component of the rotating shaft structure switches from the first rotating shaft to the second rotating shaft), then the curve of rotational torque versus rotational angle between the first and second rotating shafts when the rotation angle is between 70 and 120 degrees is plotted. Figure 5 The figure shown is a schematic diagram of the rotational torque versus rotational angle curve when the shaft structure is in the target state.

[0083] When the rotating shaft structure is in the target state, multiple different target rotation angles can be determined. The angle difference between adjacent target rotation angles is less than a certain threshold to ensure the accuracy of the constructed rotational torque versus rotational angle curve. The rotational torque corresponding to each target rotation angle is recorded, and a coordinate system is constructed. In this coordinate system, the horizontal axis represents the rotational angle, and the vertical axis represents the rotational torque. The points corresponding to each recorded target rotation angle and its corresponding rotational torque in this coordinate system are determined, and the determined points are connected to form the rotational torque versus rotational angle curve.

[0084] The detection method disclosed in this embodiment determines the target correspondence between the rotational torque and rotational angle of the rotating shaft structure when it is in a target state. Based on this target correspondence, a curve of rotational torque versus rotational angle is determined for the rotating shaft structure in the target state. Analysis of this curve determines whether the rotating shaft structure meets the conditions. In this solution, the target correspondence of the rotating shaft structure in the target state is plotted as a curve of rotational torque versus rotational angle. This allows for direct determination of whether the rotating shaft structure meets the conditions using this curve. Analysis of the rotating shaft structure through the curve is clear and precise, improving the accuracy of determining whether the rotating shaft structure meets the conditions and effectively avoiding problems such as jamming or void formation in the rotating shaft structure during practical applications.

[0085] Furthermore, in the detection method disclosed in this embodiment, determining the target correspondence between the rotational torque and rotation angle of the shaft structure when the shaft structure is in the target state can also be:

[0086] During the rotation of the shaft structure, the rotation angle between the first shaft and the second shaft is detected; the correspondence between the rotational torque and the rotation angle of the shaft structure during the rotation is constructed; and the target correspondence between the rotational torque and the rotation angle of the shaft structure when the shaft structure is in the target state is determined from the correspondence.

[0087] That is, as long as the shaft structure is in the process of rotation, the correspondence between the rotational torque and the rotation angle of the shaft structure is determined, and the target correspondence is determined from the correspondence between the rotational torque and the rotation angle of the shaft structure.

[0088] Specifically, as long as the rotating shaft structure is detected to be in the process of rotation, the angle between the first rotating shaft and the second rotating shaft is detected, the rotational torque of the rotating shaft structure is determined, and the correspondence between the rotational torque and the rotational angle of the rotating shaft structure is constructed. This correspondence includes not only the correspondence between the rotational torque and the rotational angle when the rotating shaft structure is in the target state, but also the correspondence between the rotational torque and the rotational angle when the rotating shaft structure is in a non-target state. That is, the constructed correspondence between the rotational torque and the rotational angle is a complete relationship corresponding to the rotation of the rotating shaft structure.

[0089] After determining the complete correspondence during the rotation of the shaft structure, the target correspondence when the shaft structure is in the target state can be extracted from the complete correspondence. For example, record the complete correspondence between rotational torque and rotation angle during the complete process of the shaft structure from the start to the end of rotation. Then, extract the correspondence between rotational torque and rotation angle when the shaft structure is in the target state (e.g., the rotation angle between the first shaft and the second shaft is 70-120 degrees) from the recorded complete correspondence. This correspondence is the target correspondence.

[0090] Specifically, after extracting the target correspondence of the shaft structure in the target state from the complete correspondence of the records, the curve corresponding to the target correspondence can be constructed, that is, the rotational torque and rotation angle curve when the shaft structure is in the target state can be constructed, so as to determine whether the shaft structure meets the conditions based on the curve.

[0091] Alternatively, after determining the complete correspondence during the rotation of the shaft structure, a complete rotational torque and rotational angle curve can be directly constructed based on this complete correspondence. That is, the curve includes the rotational torque and rotational angle curves during the complete process of the shaft structure from the start of rotation to the end of rotation, so as to directly determine the curve portion corresponding to the shaft structure in the target state from the complete rotational torque and rotational angle curves, and determine whether the shaft structure meets the conditions based on the curve portion.

[0092] like Figure 6 As shown, the complete rotational torque and rotational angle curves are constructed, including curve a and curve b. Curve a is the rotational torque and rotational angle curve corresponding to the rotational angle between the first and second shafts in the shaft structure expanding from 0 degrees to 360 degrees. Curve b is the rotational torque and rotational angle curve corresponding to the rotational angle between the first and second shafts in the shaft structure closing from 360 degrees to 0 degrees. Figure 6 The regions where the relationship between rotational torque and rotational angle changes can be clearly identified. These regions represent the target relationship when the shaft structure is in the target state. Figure 6The diagram contains parts a1 and a2, and parts b1 and b2. Part a1 represents the curve portion where the rotation angle between the first and second rotating shafts continuously increases and where the shaft switches from the first to the second rotating shaft, with a rotation angle range of 70-120 degrees. Part a2 represents the curve portion where the rotation angle between the first and second rotating shafts continuously increases and where the shaft switches from the second to the first rotating shaft, with a rotation angle range of 240-280 degrees. Part b1 represents the curve portion where the rotation angle between the first and second rotating shafts continuously decreases and where the shaft switches from the first to the second rotating shaft, with a rotation angle range of 280-240 degrees. Part b2 represents the curve portion where the rotation angle between the first and second rotating shafts continuously decreases and where the shaft switches from the second to the first rotating shaft, with a rotation angle range of 120-70 degrees.

[0093] It should be noted that, for Figure 6 The description of the medium degree range is for illustrative purposes only and is not intended to be limiting.

[0094] This embodiment discloses a detection method, the flowchart of which is as follows: Figure 7 As shown, it includes:

[0095] Step S71: Determine the target correspondence between the rotational torque and rotation angle of the shaft structure when the shaft structure is in the target state. The target state represents the switching of the rotating component in the shaft structure based on the first shaft and the second shaft.

[0096] Step S72: Based on the target correspondence when the shaft structure is in the target state, determine the rotational torque and rotational angle curve when the shaft structure is in the target state;

[0097] Step S73: Determine multiple sets of adjacent points on the curve of rotational torque versus rotational angle, with each set of adjacent points including two adjacent torque detection points;

[0098] Step S74: Determine the slope of the straight line formed by each group of adjacent points;

[0099] Step S75: Based on the comparison results between the slopes and slope ranges corresponding to multiple sets of adjacent points, determine whether the rotating shaft structure meets the conditions.

[0100] The target correspondence between the rotational torque and rotational angle of the rotating shaft structure is determined when the rotating shaft structure is in the target state. The target state represents the switching between the rotating components in the rotating shaft structure based on the first rotating shaft and the second rotating shaft. Based on the target correspondence when the rotating shaft structure is in the target state, it is determined whether the rotating shaft structure meets the conditions. This is to enable the judgment of whether the rotating shaft structure meets the conditions by using the target correspondence between the rotational torque and rotational angle of the rotating shaft structure, so as to avoid problems such as jamming or empty stroke of the rotating shaft structure during application.

[0101] In determining whether the rotating shaft structure meets the conditions, the target correspondence when the rotating shaft structure is in the target state can be plotted as a curve of rotational torque and rotational angle when the rotating shaft structure is in the target state. This allows for the determination of whether the conditions are met based on the curve of rotational torque and rotational angle when the rotating shaft structure is in the target state.

[0102] Specifically, multiple sets of adjacent points can be determined on the rotational torque versus rotational angle curve. Each set of adjacent points includes two adjacent torque detection points. The slope of the straight line formed by each set of adjacent points is determined. Based on the comparison results between the slopes and slope ranges corresponding to multiple sets of adjacent points, it is determined whether the shaft structure meets the conditions.

[0103] After obtaining the rotational torque and rotational angle curve when the shaft structure is in the target state, since the curve corresponds to the shaft structure in the target state, the detection method disclosed in this embodiment is to detect whether there will be jamming or empty stroke when the shaft structure is in the target state. Therefore, the rotational torque and rotational angle curve when the shaft structure is in the target state can be directly processed.

[0104] Specifically, multiple torque detection points are determined from the curve, and each pair of adjacent torque detection points on the curve is defined as a group of adjacent points to obtain multiple groups of adjacent points. The slope of the straight line formed by each group of adjacent points is then determined. For example... Figure 8 The diagram shows a schematic of the rotational torque versus rotational angle curve of a rotating shaft structure in a target state. Eight torque detection points are identified in this curve: F1, F2, F3, F4, F5, F6, F7, and F8. These eight torque detection points can form multiple groups of adjacent points, including: (F1, F2), (F2, F3), (F3, F4), (F4, F5), (F5, F6), (F6, F7), and (F7, F8). The slope of the straight line formed by each group of adjacent points can be determined, as shown below. Figure 8 The slope of the straight line formed by the adjacent point group (F2, F3) and the slope of the straight line formed by the adjacent point group (F4, F5) can be determined by the coordinates of each torque detection point in the curve.

[0105] In this embodiment, the condition of whether the shaft structure meets the requirements is determined by the slope of the straight line formed by each group of adjacent points on the curve of rotational torque and rotational angle when the shaft structure is in the target state. Each group of adjacent points includes two adjacent torque detection points. Therefore, when determining the adjacent torque detection points, the distance between the adjacent torque detection points must be limited to a fixed value. This distance can be specifically the difference in rotational angle between two adjacent torque detection points in order to ensure that the slope formed by each group of adjacent points is always within a certain range.

[0106] Specifically, the target angle is determined, which corresponds to the change in the rotation angle between the first and second shafts. On the rotation torque versus rotation angle curve, a torque detection point is determined at each target angle interval, and the target angle interval is between two torque detection points in each group of adjacent points.

[0107] In this embodiment, the change in rotation angle between the first and second rotating shafts is used as a parameter to determine another torque detection point in the adjacent point group. For example, to determine the first torque detection point on the rotation torque versus rotation angle curve, and to determine the second torque detection point in the same group of adjacent points as the first torque detection point, the first rotation angle value of the first torque detection point on the rotation torque versus rotation angle curve can be determined first. Then, a target angle (e.g., 5 degrees, 3 degrees, etc., which remains unchanged after being set on the same rotation torque versus rotation angle curve) is added to the first rotation angle value to obtain the second rotation angle value after adding the target angle. The point on the rotational torque versus rotational angle curve corresponding to the second rotational angle value is determined as the second torque detection point. This second torque detection point can be combined with the first torque detection point as a group of adjacent points. Alternatively, the target angle can be reduced from the first rotational angle value (e.g., 5 degrees, 3 degrees, etc., the target angle remains unchanged after being set on the same rotational torque versus rotational angle curve) to obtain a third rotational angle value with the increased target angle. The point on the rotational torque versus rotational angle curve corresponding to this third rotational angle value is determined as the third torque detection point. This third torque detection point can be combined with the first torque detection point as a group of adjacent points. After determining one group of adjacent points, other groups of adjacent points need to be determined according to the determined target angle until adjacent point groups have been determined at different positions on the rotational torque versus rotational angle curve when the shaft structure is in the target state. Based on these multiple groups of adjacent points, it can be determined whether the shaft structure meets the conditions.

[0108] The slope of the straight line formed by each group of adjacent points is compared with the slope range to obtain the comparison result. Based on the comparison result, it can be determined whether the shaft structure meets the conditions.

[0109] The slope range is preset and can be determined through multiple experiments or obtained through training. The slope range can be 0.2 to -0.2. As long as it is within this slope range, the curve is considered to be relatively smooth and without any pauses.

[0110] The condition can be determined by whether the slope of the straight line formed by each group of adjacent points is within the slope range. After obtaining the conclusion that each group of adjacent points meets the condition, the condition of the rotating shaft structure can be determined based on the conclusion that each group of adjacent points meets the condition.

[0111] If the slope of a straight line formed by a group of adjacent points is within the slope range, it can be determined that the curve segment corresponding to the group of adjacent points is gentle and the curve segment satisfies the condition (i.e., the group of adjacent points satisfies the condition); if the slope of a straight line formed by a group of adjacent points is not within the slope range, it can be determined that the curve segment corresponding to the group of adjacent points is not gentle and the curve segment does not satisfy the condition (i.e., the group of adjacent points does not satisfy the condition).

[0112] After determining whether each group of adjacent points meets the conditions, if it is determined that all curve segments in the curve meet the conditions (i.e., each group of adjacent points in all adjacent point groups meets the conditions), then it can be determined that the curve is smooth, that is, the pivot structure meets the conditions.

[0113] Alternatively, if it is determined that the slope of a certain number of adjacent point groups in a set of adjacent points is not within the slope range, then the rotation axis structure is deemed not to meet the condition. For example, if the target number is 2, then the rotation axis structure is deemed not to meet the condition if the slope of 2 adjacent point groups is not within the slope range. It should be noted that these 2 adjacent point groups do not necessarily have to be adjacent point groups on the curve under the same target state, but rather the total number of adjacent point groups on the curve under multiple different target states whose slopes are not within the slope range. Multiple different target states can be, for example,... Figure 6 As shown, Figure 6 a1, a2, b1, and b2 represent various different target states, although Figure 6 a1, a2, b1, and b2 are all in the target state, but they correspond to different switching states between the first and second rotating axes.

[0114] In addition, when determining whether the shaft structure meets the conditions, it is necessary to determine the rotational torque and rotational angle curves of the shaft structure in each target state, and to determine whether the rotational torque and rotational angle curves of the shaft structure in each target state meet the conditions. Only when the curves corresponding to each target state meet the conditions can it be determined that the shaft structure meets the conditions.

[0115] If the curve corresponding to one (or a number of) target states does not meet the conditions, or if one (or a number of) curve segments in the curves corresponding to one target state does not meet the conditions, then it can be determined that the rotating shaft structure does not meet the conditions.

[0116] The detection method disclosed in this embodiment, after determining the rotational torque and rotational angle curves of the rotating shaft structure in the target state based on the target correspondence, determines multiple sets of adjacent points on the rotational torque and rotational angle curves. Each set of adjacent points includes two adjacent torque detection points. The slope of the straight line formed by each set of adjacent points is determined. Based on the comparison results between the slopes and slope ranges corresponding to the multiple sets of adjacent points, it is determined whether the rotating shaft structure meets the conditions. This scheme, after determining the rotational torque and rotational angle curves of the rotating shaft structure in the target state, determines whether the rotating shaft structure meets the conditions based on the slope of the straight line formed by each set of adjacent points on the curve. By determining the slope between adjacent points on the curve, the determination of whether the rotating shaft structure meets the conditions is achieved, ensuring the efficiency of the determination and providing the accuracy of the determination.

[0117] Furthermore, in the detection method disclosed in this embodiment, if it is determined that the slope corresponding to each group of adjacent points in multiple groups of adjacent points is within the slope range, and the rotating shaft structure is determined to meet the condition, it may further include:

[0118] If the slope corresponding to each group of adjacent points in a plurality of adjacent points is determined to be within the range of the first slope, the rotating shaft structure is determined to satisfy the first condition; if the rotating shaft structure satisfies the first condition, the range of rotation angles between the first and second rotating shafts and the trend of rotation angle changes when the rotating shaft structure is currently in the target state are determined; the second slope range is determined based on the range of rotation angles and the trend of rotation angle changes; if the slope corresponding to each group of adjacent points in a plurality of adjacent points is determined to be within the range of the second slope, the rotating shaft structure is determined to satisfy the second condition, and the accuracy of the rotating shaft structure satisfying the second condition is higher than the accuracy of satisfying the first condition.

[0119] When determining whether the shaft structure meets the conditions, the judgment can be divided into two parts: first, determine whether the shaft structure is qualified (i.e., determine whether the shaft structure meets the first condition); and second, based on the determination that the shaft structure is qualified, further determine whether the shaft structure meets the higher precision requirements (i.e., determine whether the shaft structure meets the second condition).

[0120] The qualification of the rotating shaft structure can be determined by whether the slope of each group of adjacent points falls within a first slope range. This first slope range is applicable to the determination range of curve slope under any target state; that is, this first slope range is applicable to conditions such as... Figure 6Determine whether any one of the curve segments (a1, a2, b1, and b2) is qualified.

[0121] When the shaft structure is in the target state, each part of the curve in the curve of rotational torque versus rotational angle (corresponding to) Figure 6 If the slope of each set of adjacent points (a1, a2, b1, and b2) is within the range of the first slope, then the shaft structure is qualified. In this case, the shaft structure can be applied to electronic devices and will not experience jamming or empty travel during use.

[0122] If the hinge structure is to be applied to high-precision electronic devices, further evaluation is needed to determine whether it can meet the higher precision requirements. This involves determining the range of rotation angles between the first and second hinges and the trend of these angle changes when the hinge structure is currently in the target state. In other words, it's about determining the rotation angles corresponding to the current rotation process of the hinge structure. Figure 6 Is it part a1, part a2, part b1, or part b2?

[0123] Determine the trend of the rotation angle change, that is, determine whether the rotation angle increases or decreases during the rotation of the shaft structure. If it increases, meaning the shaft structure is switching from a smaller rotation angle to a larger rotation angle, then it corresponds to... Figure 6 Curve a in the diagram; if the rotation angle is continuously decreasing, meaning the shaft structure is switching from a larger rotation angle to a smaller rotation angle, then it can be determined that it corresponds to... Figure 6 Curve b in the diagram.

[0124] By determining the range of rotation angles, it is possible to pinpoint whether the current target state during rotation corresponds to the target state of switching from the first axis to the second axis, or the target state of switching from the second axis to the first axis.

[0125] If the current position is determined based on the trend of rotation angle change, then... Figure 6 If curve a is found in the graph, and the current rotation angle range corresponds to the first angle range (e.g., 70 degrees - 120 degrees), then it can be determined that the rotating structure is currently switching from the first axis of rotation to the second axis of rotation. Therefore, it can be directly determined that the current state corresponds to the first target state. Figure 6 The a1 part of the middle curve a, in determining the specific first target state ( Figure 6 After the a1 part in the middle, the second slope range 1 corresponding to the first target state can be determined, and the slope corresponding to each group of adjacent points in the current first target state can be compared with the second slope range 1 to determine whether the rotating shaft structure satisfies the second condition.

[0126] Alternatively, if the current value is determined based on the trend of the rotation angle change, then... Figure 6 If curve b is found in the graph, and the current rotation angle range corresponds to the second angle range (e.g., 240 degrees - 280 degrees), then it can be determined that the rotating structure is currently switching from the first axis of rotation to the second axis of rotation. Therefore, it can be directly determined that the current state corresponds to the second target state. Figure 6 The b2 portion of curve b, in determining the current corresponding second target state ( Figure 6 After (b2 part), the second slope range 2 corresponding to the second target state can be determined, and the slope corresponding to each group of adjacent points in the current second target state can be compared with the second slope range 2 to determine whether the rotating shaft structure satisfies the second condition.

[0127] Of course, based on the trend and range of rotation angle changes, other target states corresponding to the current rotating structure can also be determined, such as... Figure 6 a2 part or Figure 6 Part b1 in the diagram will not be explained in detail here. It should be noted that in this embodiment, the second slope range corresponding to different types of target states is different, so as to ensure that the slope corresponding to each group of adjacent points in the currently determined multiple groups of adjacent points is compared with the second slope range corresponding to its current specific target state, thereby ensuring the accuracy of the comparison result.

[0128] If it is determined that the slope corresponding to each group of adjacent points is within the range of the second slope, then the shaft structure satisfies the second condition, meaning that the shaft structure has reached a higher precision requirement and can be applied to electronic devices with higher precision requirements. If it is determined that the slope corresponding to a certain number of adjacent points is not within the range of the second slope, then the shaft structure does not satisfy the second condition. In this case, the shaft structure has not reached a higher precision requirement and cannot be applied to electronic devices with higher precision requirements. However, since it has satisfied the first condition, the shaft structure can be applied to electronic devices with lower precision requirements to ensure the application rate of the shaft structure.

[0129] This embodiment discloses a detection method, the flowchart of which is as follows: Figure 9 As shown, it includes:

[0130] Step S91: Determine the target correspondence between the rotational torque and rotation angle of the rotating shaft structure when the rotating shaft structure is in the target state. The target state characterizes the switching of the rotating component in the rotating shaft structure based on the first rotating shaft and the second rotating shaft.

[0131] Step S92: Based on the target correspondence when the shaft structure is in the target state, determine the rotational torque and rotational angle curve when the shaft structure is in the target state;

[0132] Step S93: Determine multiple sets of adjacent points on the curve of rotational torque versus rotational angle, with each set of adjacent points including two adjacent torque detection points;

[0133] Step S94: Determine the angle range;

[0134] Step S95: On the rotational torque versus rotational angle curve, determine the variation data of rotational torque at multiple adjacent points within each angle range;

[0135] Step S96: Based on the data of the change in rotational torque within each angle range, determine whether the shaft structure meets the conditions.

[0136] The target correspondence between the rotational torque and rotational angle of the rotating shaft structure is determined when the rotating shaft structure is in the target state. The target state represents the switching between the rotating components in the rotating shaft structure based on the first rotating shaft and the second rotating shaft. Based on the target correspondence when the rotating shaft structure is in the target state, it is determined whether the rotating shaft structure meets the conditions. This is to enable the judgment of whether the rotating shaft structure meets the conditions by using the target correspondence between the rotational torque and rotational angle of the rotating shaft structure, so as to avoid problems such as jamming or empty stroke of the rotating shaft structure during application.

[0137] In determining whether the rotating shaft structure meets the conditions, the target correspondence when the rotating shaft structure is in the target state can be plotted as a curve of rotational torque and rotational angle when the rotating shaft structure is in the target state. This allows for the determination of whether the conditions are met based on the curve of rotational torque and rotational angle when the rotating shaft structure is in the target state.

[0138] Specifically, multiple sets of adjacent points can be determined on the rotational torque versus rotational angle curve when the shaft structure is in the target state. Each set of adjacent points includes two adjacent torque detection points. The determination of torque detection points on the curve can be as follows: Figure 8 As shown, it will not be elaborated further here.

[0139] This embodiment differs from the previous embodiment. The previous embodiment used slope judgment to determine whether the shaft structure meets the conditions, while this embodiment uses the change data of rotational torque at multiple adjacent points within a certain angle range for judgment. That is, on the curve, the change data of rotational torque at multiple adjacent points within each angle range is determined.

[0140] The angle range can be predetermined, such as 10 degrees. Within this angle range, multiple sets of adjacent points can be included. The torque change value of each set of adjacent points is determined, and the absolute values ​​of the torque change values ​​of each set of adjacent points within this angle range are added together. The sum is determined as the rotational torque change data of multiple sets of adjacent points within this angle range. It is then determined whether this change data exceeds a certain range. If it exceeds a certain range, it can be determined that the rotational torque change within this angle range is too large. In this case, it can be determined that there is an anomaly within this angle range, and it can be further determined that the shaft structure does not meet the conditions. However, if the shaft structure is in the curve of the target state, and the rotational torque change data of each angle range does not exceed the certain range, it can be determined that the rotational torque change within each angle range is normal. In this case, it can be determined that there is no anomaly within each angle range, and it can be determined that the shaft structure meets the conditions.

[0141] like Figure 10 The diagram shows the rotational torque versus rotational angle curves when the shaft structure is in the target state. It includes multiple torque detection points, such as F4 (x1, y1), F5 (x2, y2), F6 (x3, y3), and F7 (x4, y4). Specifically, the coordinates of torque detection point F4 are (x1, y1), meaning the rotational angle of F4 is x1 and the rotational torque is y1; the coordinates of torque detection point F5 are (x2, y2), meaning the rotational angle of F5 is x2 and the rotational torque is y2; the coordinates of torque detection point F6 are (x3, y3), meaning the rotational angle of F6 is x3 and the rotational torque is y3; and the coordinates of torque detection point F7 are (x4, y4), meaning the rotational angle of F7 is x4 and the rotational torque is y4.

[0142] This allows us to determine multiple sets of adjacent points, such as: the first set of adjacent points (F4, F5), the second set of adjacent points (F5, F6), and the third set of adjacent points (F6, F7). If the determined angle range is the same as |x4-x1|, then we need to determine the absolute value of the torque change value of each set of adjacent points, namely: |y2-y1|, |y3-y2|, and |y4-y3|. Then, we add the absolute values ​​of the torque change values ​​of the three sets of adjacent points together to get the rotational torque change data A within that angle range. The rotational torque change data A is: A = |y2-y1| + |y3-y2| + |y4-y3|. We then determine whether this change data exceeds the predetermined range, thereby determining whether the shaft structure meets the conditions.

[0143] If the change in rotational torque data A is determined to be within the predetermined range, the shaft structure is deemed to meet the conditions; if the change in rotational torque data A is determined to be within the predetermined range, the shaft structure is deemed to not meet the conditions.

[0144] For example, if the predetermined range is 2.1, and A ≤ 2.1, then it can be determined that the change in rotational torque within this angle range is within the normal range, and the shaft structure meets the conditions; if A > 2.1, then it can be determined that the change in rotational torque within this angle range is large, and the shaft result does not meet the conditions.

[0145] Furthermore, based on the variation data of rotational torque within each angle range, it can be determined whether the shaft structure meets the conditions. This can be achieved by: for any target state of the shaft structure, the predetermined range corresponding to the variation data of rotational torque within each angle range is the same. That is, as long as the shaft structure is in any target state, the variation data of rotational torque within each angle range is within the first predetermined range (e.g., less than or equal to 2.1). Then, it can be determined that the shaft structure meets the first condition. Meeting the first condition means that the shaft structure is qualified and can be applied to electronic devices. Moreover, there will be no jamming or empty travel during the application process.

[0146] In order to enable the rotating shaft structure to be applied to electronic devices with higher precision requirements, the precision of the rotating shaft result can be further judged. That is, for each target state, a second predetermined range can be provided, and the second predetermined range corresponding to different target states can be different.

[0147] For example: If the rotating shaft structure is determined to be in a certain position... Figure 6 If the target state corresponds to part a1, then the second predetermined range corresponding to the target state corresponding to part a1 is determined. For example, if it is 2.0, then it is necessary to determine whether the change data of rotational torque in each angle range under the current target state is greater than 2.0 (the second predetermined range corresponding to the target state corresponding to part a1). If the change data is greater than 2.0, then it can be determined that the shaft structure does not meet the second condition under the current target state and cannot be applied to electronic devices with higher precision. When the change data of rotational torque of the shaft structure in each angle range under each target state is within the first predetermined range, then it can be determined that the shaft structure is qualified and can be applied to electronic devices with low precision requirements. At this time, it is not necessary to continue to judge whether the change data of rotational torque under other target states exceeds the corresponding second predetermined range.

[0148] If the change in rotational torque within each angle range in the target state corresponding to part a1 is no greater than 2.0, then the shaft structure can continue to rotate. When it is determined that the shaft structure is in a certain position... Figure 6If the target state corresponds to part a2, then the second predetermined range corresponding to the target state corresponding to part a2 is determined. For example, if it is 1.8, then it is necessary to determine whether the change data of rotational torque in each angle range under the current target state is greater than 1.8 (the second predetermined range corresponding to the target state corresponding to part a2). If the change data is greater than 1.8, then it can be determined that the shaft structure does not meet the second condition under the current target state and cannot be applied to electronic devices with higher precision. When the change data of rotational torque of the shaft structure in each angle range under each target state is within the first predetermined range, then it can be determined that the shaft structure is qualified and can be applied to electronic devices with low precision requirements. At this time, it is not necessary to continue to judge whether the change data of rotational torque under other target states exceeds the corresponding second predetermined range.

[0149] If the change in rotational torque within each angle range under the target state corresponding to section a2 is no greater than 1.8, then it can be further determined whether the change in torque under other target states exceeds the corresponding second predetermined range. When it is determined that the shaft is in... Figure 6 If the target state corresponds to part b2, then the second predetermined range corresponding to the target state corresponding to part b2 is determined. For example, if it is 1.6, then it is necessary to determine whether the change data of rotational torque in each angle range under the current target state is greater than 1.6 (the second predetermined range corresponding to the target state corresponding to part b2). If the change data is greater than 1.6, then it can be determined that the shaft structure does not meet the second condition under the current target state and cannot be applied to electronic devices with higher precision. When the change data of rotational torque of the shaft structure in each angle range under each target state is within the first predetermined range, then it can be determined that the shaft structure is qualified and can be applied to electronic devices with low precision requirements. At this time, it is not necessary to continue to judge whether the change data of rotational torque under other target states exceeds the corresponding second predetermined range.

[0150] If the change in rotational torque within each angle range under the target state corresponding to part b2 is no greater than 1.6, then the shaft structure can be further determined to be in a state of equilibrium. Figure 6 If the target state corresponding to part b1 exceeds the corresponding second predetermined range, the second predetermined range corresponding to the target state corresponding to part b1 can be 1.9. Then it is necessary to determine whether the change data of rotational torque in each angle range under the current target state is greater than 1.9 (the second predetermined range corresponding to the target state corresponding to part b1). If the change data is greater than 1.9, it can be determined that the shaft structure does not meet the second condition under the current target state and cannot be applied to electronic devices with higher precision. When the change data of rotational torque of the shaft structure in each angle range under each target state is within the first predetermined range, it can be determined that the shaft structure is qualified and can be applied to electronic devices with low precision requirements.

[0151] If the change in rotational torque within each angle range in the target state corresponding to part b1 is no greater than 1.9, and the change in rotational torque within each angle range in the target state corresponding to part b2 is no greater than 1.6, the change in rotational torque within each angle range in the target state corresponding to part a2 is no greater than 1.8, and the change in rotational torque within each angle range in the target state corresponding to part a1 is no greater than 2.0, then it can be determined that the shaft structure meets the second condition and can be applied to electronic devices with higher precision.

[0152] It should be noted that the values ​​2.0, 1.8, 1.6, and 1.9 mentioned in this embodiment are exemplary values ​​within the second predetermined range corresponding to different states of the rotating shaft structure, and are not intended to limit its use.

[0153] Of course, when determining whether the shaft structure meets the conditions, it can be based not only on the variation data of rotational torque at multiple adjacent points within a certain angle range, but also on the slope of the straight line formed by each group of adjacent points. That is, only when the variation data of rotational torque at multiple adjacent points within each angle range is within a predetermined range, and the slope of the straight line formed by each group of adjacent points is within the slope range, can the shaft structure be determined to meet the conditions; otherwise, the shaft structure is determined not to meet the conditions.

[0154] Furthermore, it should be noted that in the detection method disclosed in this embodiment, determining whether the rotating shaft structure is in the target state can be achieved through at least one of the following methods:

[0155] Determining that the rotation angle between the first and second rotating axes is within the target range—that is, as long as the rotation angle between the first and second rotating axes is within the target range—means that the rotating structure is currently in the target state. At this point, the current state needs to be judged to determine whether the current state meets the conditions. It should be noted that the target range is not unique; different target states correspond to different rotation angles between the first and second rotating axes. Therefore, the target range can be set according to different target states.

[0156] If the torque change rate of adjacent torque detection points of the rotating shaft structure is greater than the target value, then the rotating shaft structure is currently in the target state. If the torque change rate of adjacent torque detection points suddenly changes, it indicates that the rotating component is switching, and therefore, it can be determined that the current rotating shaft structure is in the target state.

[0157] Alternatively, the target state can be determined by directly detecting the switching of the rotating component in the shaft structure from the first shaft to the second shaft or vice versa. This means that the switching of the rotating component can be detected directly without monitoring the data during the rotation of the shaft structure.

[0158] The detection method disclosed in this embodiment, after determining the rotational torque and rotational angle curves of the rotating shaft structure in the target state, determines multiple sets of adjacent points on the rotational torque and rotational angle curves. Each set of adjacent points includes two adjacent torque detection points. The angle range is determined, and the variation data of the rotational torque at multiple sets of adjacent points within each angle range on the curve is determined. Based on this variation data, it is determined whether the rotating shaft structure meets the conditions. This solution, when analyzing the rotational torque and rotational angle curves of the rotating shaft structure in the target state, needs to determine the variation data of the rotational torque at multiple sets of adjacent points on the curve within a certain angle range. Based on this variation data, it determines whether the rotating shaft structure meets the conditions. This avoids detecting whether the variation data of rotational torque within a certain angle range is too large, thus realizing the detection of whether the rotating shaft structure meets the conditions, and determining whether problems such as jamming or idle travel will occur during the application of the rotating shaft structure.

[0159] This embodiment discloses a detection device, the structural schematic diagram of which is shown below. Figure 11 As shown, it includes:

[0160] The system comprises a first body 111, a second body 112, a rotating shaft structure 113, a sensor 114, and a processor 115.

[0161] The rotating shaft structure 113 is disposed between the first body 111 and the second body 112, so that the included angle between the first body 111 and the second body 112 changes.

[0162] Sensor 114 is used to determine the rotational torque of the shaft structure 113;

[0163] The processor 115 is used to determine the target correspondence between the rotational torque and rotational angle of the rotating shaft structure 113 when the rotating shaft structure 113 is in the target state. The target state represents the switching of the rotating component in the rotating shaft structure 113 based on the first rotating shaft and the second rotating shaft. Based on the target correspondence when the rotating shaft structure 113 is in the target state, it determines whether the rotating shaft structure 113 meets the conditions.

[0164] The detection device disclosed in this embodiment is based on the detection method disclosed in the above embodiments, and will not be described again here.

[0165] The detection device disclosed in this embodiment determines the target correspondence between the rotational torque and rotation angle of the rotating shaft structure when it is in a target state. The target state characterizes the switching between the first and second rotating shafts of the rotating components in the rotating shaft structure. Based on the target correspondence when the rotating shaft structure is in the target state, it determines whether the rotating shaft structure meets the conditions. This solution determines that the rotating shaft structure is in a target state based on the switching between the first and second rotating shafts of the rotating components in the rotating shaft structure, and determines the target correspondence between the rotational torque and rotation angle of the rotating shaft structure when it is in the target state. Based on this, it determines whether the rotating shaft structure meets the conditions, thereby realizing the detection of the rotating shaft structure to determine whether problems such as jamming or idle travel will occur during the application of the rotating shaft structure.
