Detailed Implementation

[0025] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. 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.

[0026] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0027] In the following description, the terms "first" and "second" are used merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first" and "second" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0028] In related technologies, known solutions for adjusting shaft torque rely on manual adjustment based on work experience. These technologies require a long adjustment time and have low accuracy, resulting in both low precision and low efficiency in shaft torque adjustment.

[0029] The aforementioned methods for adjusting the hinge torque provided by related technologies suffer from long adjustment times and low accuracy, resulting in both low precision and low efficiency. The method of this application addresses these issues by obtaining a first parameter and a first torque change value of the hinge, where the first parameter characterizes the relationship between the torque change value and the angle; determining a first angle corresponding to the first torque change value based on the first parameter; and adjusting the hinge torque based on the first angle. This intelligently adjusts the hinge torque, automatically determining the required adjustment angle for the laptop's hinge torque without requiring manual intervention. It also automatically loosens or tightens the corresponding locking nut mechanism to precisely adjust the laptop's hinge torque to meet specifications. The process is stable, reducing the time required for hinge torque adjustment and thus improving both precision and efficiency. Therefore, compared to the long adjustment time and low precision of related technologies, the hinge torque adjustment method of this application significantly improves both precision and efficiency.

[0030] The processing flow of the shaft torque adjustment method provided in the embodiments of this application is described below. See [link to relevant documentation]. Figure 1 , Figure 1 This is a schematic flowchart of the shaft torque adjustment method provided in the embodiments of this application. Figure 1 , will combine Figure 1 Steps S101-S103 shown will be explained.

[0031] Step S101: Obtain the first parameter and the first torque change value of the shaft. The first parameter is used to characterize the relationship between the torque change value of the shaft and the angle.

[0032] In some embodiments, the first parameter may include a parameter characterizing the relationship between the torque variation of the shaft and the angle. The torque of the shaft can be generated by rotational friction between the cam, concave wheel, shim, rotating bearing, and shaft. A spring applies a normal force to the friction surfaces of the cam, concave wheel, shim, rotating bearing, and shaft. There are four pairs of friction surfaces between the cam, concave wheel, shim, rotating bearing, and shaft. Simplifying these four pairs of friction surfaces to one pair, the torque variation of the shaft... With angle The relationship between them can be expressed by the following formula (1): (1) The first parameter X can be represented by the following formula (2): (2) Where R is the outer diameter of the friction surface. Let be the inner diameter of the friction surface, and r be the inner diameter of a unit micro-ring. The normal force acting on a unit micro-ring. Let F be the coefficient of kinetic friction between the friction surfaces, and F be the normal force exerted by the spring on the friction surfaces of the cam, concave wheel, washer, rotating bearing, and rotating shaft. The width of the unit micro-ring. The coefficient of kinetic friction between the friction surfaces of the rotating bearing and the rotating shaft. The coefficient of kinetic friction between the friction surfaces of the gasket and the rotating bearing. The coefficient of kinetic friction between the friction surfaces of the concave wheel and the washer is given. Let be the coefficient of kinetic friction between the friction surfaces of the cam and the concave wheel, K be the elastic coefficient of the spring, and L be the screw pitch of the locking nut mechanism.

[0033] In some embodiments, before step S101, the shaft torque adjustment method may further include: obtaining a first pressure corresponding to the friction surface of the shaft; in response to the first pressure satisfying a preset pressure threshold, obtaining a first number of sample angles of the shaft and a sample torque corresponding to each sample angle; and determining a first parameter based on the sample angles and sample torques.

[0034] In some embodiments, the first pressure may include: the normal pressure applied by the spring to the friction surfaces of the cam, concave wheel, washer, rotating bearing, and shaft. The preset pressure threshold may include a pre-set minimum normal pressure applied by the spring to the friction surfaces of the cam, concave wheel, washer, rotating bearing, and shaft. The sample angle may include: the angle change value of the locking nut mechanism corresponding to the shaft. The sample torque may include: the torque change value of the shaft corresponding to the angle change value of the locking nut mechanism. One sample angle of a shaft corresponds to one sample torque. The sample angle and sample torque are proportional. In response to the first pressure being greater than or equal to the preset pressure threshold, it is determined that the first pressure meets the preset pressure threshold. The first quantity may include N, where N is a positive integer; the specific quantity is not limited in this application embodiment.

[0035] In the specific implementation of determining the first parameter based on sample angle and sample torque, it may include: determining a first quotient of each sample torque and the sample angle corresponding to the sample torque; determining the average value of the first quotient based on a first quantity; and determining the average value of the first quotient as the first parameter.

[0036] As an example, the preset pressure threshold is 0.5N, and the first quantity is 3. First, the first pressure corresponding to the friction surface of the shaft is obtained as 0.6N. In response to the first pressure of 0.6N being greater than the preset pressure threshold of 0.5N, the sample angle of the shaft (10°) and the corresponding sample torque (1N) are obtained. m; Obtain the sample angle of the rotating shaft (20°) and the corresponding sample torque (2.1N) at 20°. m; Obtain the sample angle of 30° on the rotating shaft and the corresponding sample torque of 3.3N. m. Determine the sample torque 1N. The first quotient of m and the sample angle of 10° is 0.1; the sample torque is determined to be 2.1 N. The first quotient of m and the sample angle 20° is 0.105; the sample torque is determined to be 3.3 N. The first quotient of m and the sample angle 30° is 0.11. The average value of the first quotient is determined to be 0.105. The average value of the first quotient, 0.105, is determined as the first parameter.

[0037] Step S102: Based on the first parameter, determine the first angle corresponding to the first torque change value.

[0038] In some embodiments, step S102 may include: determining a second quotient between a first torque change value and a first parameter; and determining the second quotient as a first angle. The first torque change value of the shaft may include the difference between the standard torque value of the shaft and the torque value before the torque change. The first angle is positive when the first torque change value is positive, and negative when the first torque change value is negative. The standard torque value of the shaft is a preset torque value.

[0039] As an example, the first torque change value is 3.5N. m, the first parameter is 0.105. The first torque change value is determined to be 3.5 N. The second quotient of m and the first parameter 0.105 is 33.33. Therefore, the first angle is determined to be 33.33°.

[0040] Step S103: Adjust the torque of the rotating shaft based on the first angle.

[0041] In some embodiments, step S103 may include: determining the rotation angle and rotation direction of the locking nut mechanism corresponding to the rotating shaft based on the first angle; and rotating the locking nut mechanism based on the rotation angle and rotation direction to adjust the torque of the rotating shaft.

[0042] As an example, the tightening direction of the locking nut mechanism is clockwise, and the loosening direction is counterclockwise. With a first angle of 33.33°, the rotation angle of the locking nut mechanism corresponding to the rotating shaft is determined to be 33.33°, and the rotation direction is clockwise. Based on the rotation angle and rotation direction, the nut included in the locking nut mechanism is rotated 33.33° clockwise to adjust the torque of the rotating shaft.

[0043] In some embodiments, after step S103, the shaft torque adjustment method may further include: obtaining a second torque change value of the shaft; determining a third quotient of the second torque change value and a first angle, and using the third quotient as a second parameter; and updating the first parameter based on the second parameter. The second torque change value of the shaft may include the difference between the adjusted torque value and the torque value before adjustment.

[0044] As an example, the second torque change value is 3N. m, the first angle is 33.33°. The second torque change value is determined to be 3N. The third quotient of m and the first angle 33.33° is 0.090. Therefore, the second parameter is determined to be 0.090.

[0045] For updating the first parameter based on the second parameter, the specific implementation may include: storing the second parameter in a parameter set; determining the number of times the parameter set is stored; in response to the number of times the parameter set is stored meeting a preset storage count threshold, determining the average value of the second parameter corresponding to all storage counts, and resetting the storage count to zero; replacing the first parameter based on the average value of the second parameter corresponding to all storage counts. The preset storage count threshold may include a pre-set minimum number of storage counts. Preferably, it is 100 times, but this application embodiment does not limit the specific number of storage counts. In response to the number of times the parameter set is stored being greater than or equal to the preset storage count threshold, it is determined that the number of times the parameter set is stored meets the preset storage count threshold. Each time a second parameter is stored in the parameter set, the storage count of the parameter set increases by one.

[0046] As an example, the preset storage count threshold is 3 times. The second parameter 1 is 0.9, the second parameter 2 is 0.8, and the second parameter 3 is 1. Storing the second parameter 1 into parameter set A determines that parameter set A has been stored 1 time; storing the second parameter 2 into parameter set A determines that parameter set A has been stored 2 times; storing the second parameter 3 into parameter set A determines that parameter set A has been stored 3 times. In response to the fact that the storage count of parameter set A is 3 times, which equals the preset storage count threshold of 3 times, the average value of the second parameters 1, 2, and 3 is determined to be 0.9, and the storage count is reset to zero. Finally, the first parameter is replaced based on the average value of the second parameters, which is 0.9.

[0047] In some embodiments, the processing flow of the shaft torque adjustment method is illustrated. Figure 2 ,like Figure 2 As shown, it includes: Step S201: Obtain the first pressure corresponding to the friction surface of the rotating shaft.

[0048] Step S202: In response to the first pressure meeting a preset pressure threshold, obtain the sample angles of a first number of rotating shafts and the sample torque corresponding to each sample angle.

[0049] Step S203: Determine the first quotient of the sample torque and the sample angle corresponding to the sample torque for each sample.

[0050] Step S204: Determine the average value of the first quotient based on the first quantity.

[0051] Step S205: Determine the average value of the first quotient as the first parameter.

[0052] As an example, for steps S201-S205, in specific implementation, the preset pressure threshold is 0.5N, and the first quantity is 3. First, the first pressure corresponding to the friction surface of the rotating shaft is obtained as 0.5N. In response to the first pressure of 0.5N being equal to the preset pressure threshold of 0.5N, the sample angle of the rotating shaft of 10° and the sample torque of 1.1N corresponding to the sample angle of 10° are obtained. m; Obtain the sample angle of the rotating shaft -20° and the corresponding sample torque of -2.2N. m; Obtain the sample angle of the rotating shaft -30° and the corresponding sample torque of -3.3N. m. The sample torque is determined to be 1.1 N. The first quotient of m and the sample angle 10° is 0.11; the sample torque is determined to be -2.2N. The first quotient of m and the sample angle -20° is 0.11; the sample torque is determined to be -3.3N. The first quotient of m and the sample angle -30° is 0.11. The average value of the first quotient is determined to be 0.11. The average value of the first quotient, 0.11, is determined as the first parameter.

[0053] The specific explanations for each step S201-S205 are the same as those for step S101 above, and will not be repeated here.

[0054] In some embodiments, the processing flow of the shaft torque adjustment method is illustrated. Figure 3 ,like Figure 3 As shown, it includes: Step S301: Determine the second quotient of the first torque change value and the first parameter.

[0055] Step S302: Determine the second quotient as the first angle.

[0056] Step S303: Based on the first angle, determine the rotation angle and rotation direction of the locking nut mechanism corresponding to the rotating shaft.

[0057] Step S304: Based on the rotation angle and rotation direction, rotate the locking nut mechanism to adjust the torque of the shaft.

[0058] As an example, for steps S301-S304, in specific implementation, the first torque change value is -3.5N. m, the first parameter is 0.105. The first torque change value is determined to be -3.5N. The second quotient of m and the first parameter 0.105 is -33.33. Therefore, the first angle is determined to be -33.33°. The tightening direction of the locking nut mechanism is clockwise, and the loosening direction is counterclockwise. With the first angle at -33.33°, the rotation angle of the locking nut mechanism corresponding to the shaft is determined to be 33.33°, and the rotation direction is counterclockwise. Based on the rotation angle and direction, the nut included in the locking nut mechanism is rotated counterclockwise by 33.33° to adjust the torque of the shaft.

[0059] The specific descriptions of the first torque change value, first parameter, first angle, rotation angle and rotation direction of the locking nut mechanism in steps S301-S304 are the same as those in step S102 above, and will not be repeated here.

[0060] In some embodiments, the processing flow of the shaft torque adjustment method is illustrated. Figure 4 ,like Figure 4 As shown, it includes: Step S401: Obtain the second torque change value of the shaft.

[0061] Step S402: Determine the third quotient of the second torque change value and the first angle, and use the third quotient as the second parameter.

[0062] Step S403: Store the second parameter into the parameter set.

[0063] Step S404: Determine the number of times the parameter set is stored.

[0064] In step S405, in response to the storage count of the parameter set meeting the preset storage count threshold, the average value of the second parameter corresponding to all storage counts is determined, and the storage count is reset to zero.

[0065] Step S406: Replace the first parameter based on the average value of the second parameter corresponding to all storage times.

[0066] As an example, for steps S401-S406, in specific implementation, the second torque change value 1 is 3N. m, the first angle 1 is 33.33°. The second torque change value is determined to be 3N. The third quotient 1 of m and the first angle 33.33° is 0.09. Therefore, the second parameter a is determined to be 0.090; the second torque change value 2 is -2N. m, the first angle 2 is -20°, and the second torque change value is determined to be -2N. The third quotient of m and the first angle -20° is 2, which is 0.1. Therefore, the second parameter b is determined to be 0.1.

[0067] The preset storage count threshold is 2 times. The second parameter a is 0.09, and the second parameter b is 0.1. Storing the second parameter a into parameter set B determines that parameter set B has been stored once; storing the second parameter b into parameter set B determines that parameter set B has been stored twice. Since the storage count of parameter set B is 2 times, which equals the preset storage count threshold of 2 times, the average value of the second parameter a and the second parameter b is determined to be 0.095, and the storage count is reset to zero. Finally, the first parameter is replaced based on the average value of the second parameter, 0.095.

[0068] The specific explanations for each step S401-S406 are the same as those for step S103 above, and will not be repeated here.

[0069] Figure 5 The diagram illustrates an application scenario of the shaft torque adjustment method provided in this application embodiment.

[0070] refer to Figure 5 This application describes an scenario where the shaft torque adjustment method provided in this embodiment is applied to the adjustment of the shaft torque of a laptop computer. A torque sensor can be used to measure the torque value of the laptop computer's shaft in real time. An angle sensor can be used to measure the angle of the nut included in the locking nut mechanism corresponding to the shaft in real time. A signal receiver can be used to acquire the shaft torque value measured by the torque sensor and send it to an industrial computer. The signal receiver can also be used to acquire the nut angle measured by the angle sensor and send it to the industrial computer. Test conditions and parameters are sent to the industrial computer. The test conditions may include: torque specifications and a preset pressure threshold. Parameters may include: a first parameter characterizing the relationship between the shaft torque change value and the angle. Based on the test conditions and parameters, the industrial computer determines the nut rotation angle and the shaft torque change value through a shaft torque adjustment algorithm. The nut rotation angle and the shaft torque change value are sent to a motion controller. The motion controller controls a torque testing motor and an electric screwdriver to adjust the nut angle in real time according to the nut rotation angle and the shaft torque change value until the shaft torque value meets the torque specifications. After the laptop's hinge torque is adjusted, the industrial computer outputs the test results, the waveform of the hinge torque, and report data for this adjustment.

[0075] Figure 7 This diagram illustrates another application scenario of the shaft torque adjustment method provided in the embodiments of this application.

[0076] refer to Figure 7 This application provides another scenario for the hinge torque adjustment method, applied to the hinge torque adjustment of a laptop computer. First, the torque value of the laptop computer's hinge is tested to see if it meets a preset torque specification. If the hinge torque value meets the preset torque specification, the torque is deemed acceptable, and the process proceeds to the next workstation without further torque adjustment. If the hinge torque does not meet the preset torque specification, the torque is deemed unacceptable, and the required rotation angle and direction of the nut in the corresponding locking nut mechanism are determined according to the hinge torque adjustment algorithm. Based on the rotation angle and direction, an electric screwdriver is controlled to automatically rotate the nut in the corresponding locking nut mechanism to adjust the hinge torque value. Upon completion of the hinge torque adjustment, the hinge torque value is retested. If the retested torque value meets the preset torque specification, the torque is deemed acceptable, and the process proceeds to the next workstation. If the retested torque value does not meet the preset torque specification, the torque is deemed unacceptable, and the hinge torque value is repeatedly adjusted according to the hinge torque adjustment algorithm until it meets the preset torque specification. Subsequent workstations may include steps in the production of laptops, such as appearance inspection and packaging.

[0077] Understandable. Figure 7 The application scenarios of the shaft torque adjustment method in this application are only some exemplary implementations in the embodiments of this application. The application scenarios of the shaft torque adjustment method in the embodiments of this application include, but are not limited to, those of... Figure 7 The application scenarios of the shaft torque adjustment method shown are illustrated. The method in this embodiment of the application obtains a first pressure corresponding to the friction surface of the shaft; in response to the first pressure satisfying a preset pressure threshold, obtains a first number of sample angles of the shaft and a sample torque corresponding to each sample angle; and determines a first parameter based on the sample angles and sample torques. Thus, a parameter characterizing the relationship between the torque change value and the angle of the shaft can be automatically determined, thereby improving the accuracy and efficiency of shaft torque adjustment. The method in this embodiment of the application determines a second quotient value between the first torque change value and the first parameter; and determines the second quotient value as a first angle. Thus, based on the parameter characterizing the relationship between the torque change value and the angle of the shaft, the angle required to adjust the shaft torque of the laptop can be automatically determined, eliminating the need for the operator to subjectively determine the adjustment angle, thus improving the accuracy and efficiency of shaft torque adjustment. The method in this embodiment of the application determines the rotation angle and rotation direction of the locking nut mechanism corresponding to the shaft based on the first angle; and rotates the locking nut mechanism based on the rotation angle and rotation direction to adjust the shaft torque. In this way, the locking nut mechanism corresponding to the hinge can be automatically loosened or tightened to precisely adjust the torque of the laptop hinge to meet the torque specifications. The process is stable, and the adjustment result of the hinge torque is not affected by personnel changes, thus improving the accuracy and efficiency of hinge torque adjustment. The method of this application embodiment obtains a second torque change value of the hinge; determines a third quotient value between the second torque change value and the first angle, and uses the third quotient value as a second parameter; and updates the first parameter based on the second parameter. In this way, the error of the first parameter caused by the tolerance of the laptop hinge components can be automatically corrected, reducing the working time of laptop hinge torque adjustment, thereby improving the accuracy and efficiency of hinge torque adjustment.
