In addition, the embodiments of the present application described below with reference to the drawings are exemplary only for explaining the embodiments of the present application and are not to be construed as limiting the present application.

Referring to fig. 1 to 3, an embodiment of the present application provides a control method of a driving mechanism 10, the control method includes:

02: acquiring an operation instruction for the display screen 20;

03: acquiring a target voltage of the detecting member 14 according to the operation instruction;

04: the driving assembly 11 is controlled to drive the display screen 20 to move according to the target voltage and the real-time voltage output by the detecting piece 14;

05: detecting whether the driving assembly 11 is locked; and

06: And under the condition that the driving assembly 11 is not locked, the step of controlling the driving assembly 11 to drive the display screen 20 to move according to the target voltage and the real-time voltage output by the detection piece 14 is performed back until the real-time voltage is equal to the target voltage.

Referring to fig. 3, the control method of the driving mechanism 10 can be applied to the driving mechanism 10, and the driving mechanism 10 according to the embodiment of the application includes a driving assembly 11, a detecting member 14 and one or more processors 15. The driving assembly 11 is used for driving the display screen 20 to move. The detecting element 14 is used for outputting a voltage according to the motion parameter of the display screen 20. One or more processors 15 are electrically connected to both the drive assembly 11 and the sensing element 14.

The display 20 is a device for displaying images, text, and video, and for example, the display 20 of the present application can display navigation information of the vehicle 100, status monitoring information of the vehicle 100, entertainment video information, and the like. Specifically, the driving assembly 11 can drive the display screen 20 to move to adjust the position of the display screen 20, so that the use requirement of the user on the display screen 20 can be ensured. It should be noted that the display 20 may include, but is not limited to, an Organic LIGHT EMITTING Diode (OLED), a Thin film transistor liquid crystal display (Thin-Film Transistor Liquid CRYSTAL DISPLAY, TFT-LCD), a capacitive touch screen (CAPACITIVE TOUCH PANEL, CTP), and the like.

For example, when the user needs to adjust the angle of the display screen 20, the user can speak a voice command to the display screen 20 to "increase the angle of the display screen 20", in which case the processor 15 can acquire the voice command and take the voice command as an operation command for the display screen 20. Also for example, when the user needs to adjust the angle of the display screen 20, the user can click a virtual key (for example, a key for "adjusting the screen angle") on the display screen 20, in which case the processor 15 can acquire a touch operation when the user clicks the virtual key, and take the touch operation as an operation instruction for the display screen 20. For another example, when the user needs to adjust the operation state of the display screen 20, the user can send a remote control instruction to the display screen 20 through another device at a position far from the display screen 20, in which case the processor 15 can acquire the remote control instruction and use it as an operation instruction for the display screen 20.

The drive assembly 11 is a component for connection to the display screen 20 and is capable of providing powered support for movement of the display screen 20. In some embodiments, the driving assembly 11 may include a driving member 111 and a transmission member 113, where the display 20 and the driving member 111 are connected to the transmission member 113, and when the driving member 111 works, the driving force of the driving member 111 can act on the display 20 through the transmission member 113 to drive the display 20 to move. Referring to fig. 4, in an embodiment of the present application, the driving assembly 11 is used to drive the display 20 between a first limit position and a second limit position. It should be noted that the driving member 111 may be a motor or a hydraulic pump. The transmission member 113 may include, but is not limited to, a rack and pinion structure, a worm and gear structure, or a gear set structure, etc.

Specifically, in some embodiments, the first limit position may be a limit position where the driving assembly 11 can drive the display screen 20 to move toward the left end in fig. 4, in other words, in a case where the driving assembly 11 drives the display screen 20 to move to the first limit position, the driving assembly 11 stops working to make the display screen 20 in the first limit position, or the driving assembly 11 drives the display screen 20 to move reversely (toward the right end in fig. 4); the second limit position may be a limit position at which the driving assembly 11 can drive the display screen 20 to move toward the right end in fig. 4, in other words, in a case where the driving assembly 11 drives the display screen 20 to move to the second limit position, the driving assembly 11 stops operating to bring the display screen 20 to the second limit position, or the driving assembly 11 drives the display screen 20 to move reversely (toward the left end in fig. 4).

Referring to fig. 2 to 4, in some embodiments, the driving mechanism 10 may further include a limit switch 12 and a blocking member 13, where one of the limit switch 12 and the blocking member 13 is disposed at a first limit position, and the other of the limit switch 12 and the blocking member 13 is disposed at a second limit position. The limit switch 12 is an electrical component capable of changing the on-off state according to the stroke position of a moving part (for example, the display screen 20, etc.), the limit switch 12 can be electrically connected with the processor 15, and the limit switch 12 can output different signals according to the on-off state thereof, for example, can output a closing signal when turned on (closed), and can output an opening signal when turned off. The blocking member 13 is a structure capable of blocking the movement of the moving part, and the blocking member 13 may be a protrusion. In the embodiment of the present application, only the case where the limit switch 12 is disposed at the first limit position and the stopper 13 is disposed at the second limit position will be described.

Specifically, in the case that the driving assembly 11 drives the display screen 20 to move so as to close the limit switch 12, the display screen 20 is located at the first limit position or the second limit position; in the case that the driving assembly 11 drives the display screen 20 to move to collide with the blocking member 13, the display screen 20 is located at the second limit position or the first limit position. It should be noted that, in the present application, the limit switch 12 is located at the first limit position, and the blocking member 13 is located at the second limit position, that is, the display screen 20 is located at the first limit position when the driving assembly 11 drives the display screen 20 to move so as to close the limit switch 12; in the case that the driving assembly 11 drives the display screen 20 to move to collide with the blocking member 13, the display screen 20 is located at the second limit position.

The detecting element 14 is an element for outputting a voltage according to a motion parameter of the display 20, for example, the detecting element 14 may output different voltages to the processor 15 according to different motion parameters of the display 20. The motion parameter may be a deflection angle of the display screen 20 or a moving distance of the display screen 20, and the like, and is not limited herein. In the present application, the motion parameter is the deflection angle of the display screen 20, and accordingly, the operation instruction for the display screen 20 may be: the deflection angle of the display screen 20 is controlled such that the display screen 20 is located at the first limit position, the second limit position, or any position between the first limit position and the second limit position.

It should be noted that in some embodiments, the detecting member 14 may include, but is not limited to, a potentiometer, an angle sensor, a gyroscope, or the like. In the present application, the detecting member 14 is a potentiometer. Specifically, the potentiometer may be disposed on the display screen 20 and move along with the display screen 20, so as to more intuitively detect the turning angle of the display screen 20 and output voltages with different magnitudes according to different turning angles. Wherein, when the display screen 20 is located at the first limit position, the voltage output by the potentiometer is the reference voltage, and in this case, the deflection angle of the display screen 20 is 0 °; during the movement of the display screen 20 from the first limit position towards the second limit position, the voltage output by the potentiometer gradually increases to the end voltage, i.e. in the case of the movement of the display screen 20 to the second limit position, the voltage output by the potentiometer is the end voltage. Of course, it will be appreciated that in other examples, in the case where the driving member 111 is a motor, the potentiometer may also be disposed on the output shaft of the motor and rotate with the output shaft, so as to detect the turning angle of the display screen 20.

The processor 15 is a component for analyzing and processing data and issuing instructions to or controlling an actuator (e.g., the drive assembly 11, etc.). The processor 15 may be one or more. The processor 15 can be communicatively connected (including wired connection or wireless connection) to the detecting member 14 to obtain voltage data output by the detecting member 14 according to the motion parameters of the display screen 20, and obtain target voltage data output by the detecting member 14 according to the operation command, and analyze and process the data to obtain an analysis result, and further issue a control command to the component of the executing mechanism according to the analysis result to control the executing mechanism, so that the executing mechanism performs the related operation according to the execution command (for example, the driving component 11 drives the display screen 20 to move according to the control command). Referring to fig. 5, in an embodiment of the present application, one or more processors 15 are capable of executing the methods 02, 03, 04, 05, and 06, i.e., the one or more processors 15 are configured to obtain operation instructions for the display 20; acquiring a target voltage of the detecting member 14 according to the operation instruction; the driving assembly 11 is controlled to drive the display screen 20 to move according to the target voltage and the real-time voltage output by the detecting piece 14; detecting whether the driving assembly 11 is locked; and under the condition that the driving assembly 11 is not locked, returning to the step of controlling the driving assembly 11 to drive the display screen 20 to move according to the target voltage and the real-time voltage output by the detecting piece 14 until the real-time voltage is equal to the target voltage.

For example, when the processor 15 obtains an operation instruction for the display screen 20, where the operation instruction is to control the display screen 20 to deflect to a central position (a distance between the central position and the first limit position and a distance between the central position and the second limit position) of the first limit position and the second limit position, the detecting element 14 can output a corresponding voltage U according to a deflection angle of the display screen 20 corresponding to the central position, where the voltage U is a target voltage, the processor 15 can obtain the target voltage and a real-time voltage (a voltage corresponding to a current deflection angle of the display screen 20) output by the detecting element 14, control the driving assembly 11 to drive the display screen 20 to move, and detect whether the driving assembly 11 is locked, and under a condition that the driving assembly 11 is not locked, continuously control the driving assembly 11 to drive the display screen 20 to move until the real-time voltage is equal to the target voltage, so that the display screen 20 can move to a position (the central position) indicated by the operation instruction.

In some embodiments, assuming that when the display 20 is located at the first limit position, the voltage output by the detecting element 14 is U1, when the display 20 is located at the second limit position, the voltage output by the detecting element 14 is U2, when the driving component 11 drives the display 20 to move from the first limit position to the second limit position, the deflection angle of the display 20 is α, and at this time, if the deflection angle of the display 20 corresponding to the operation instruction for the display 20 is β, the target voltage U may be:

In the control method of the driving mechanism 10 according to the embodiment of the present application, the driving mechanism 10 can obtain the target voltage of the detecting element 14 according to the operation command, and control the driving assembly 11 to drive the display screen 20 to move according to the target voltage and the real-time voltage output by the detecting element 14, and detect whether the driving assembly 11 is locked or not when the driving assembly 11 drives the display screen 20 to move, and return to execute the step of controlling the driving assembly 11 to drive the display screen 20 to move according to the target voltage and the real-time voltage output by the detecting element 14 until the real-time voltage is equal to the target voltage, so that on one hand, the stability of the driving assembly 11 driving the display screen 20 to move can be improved; on the other hand, the driving assembly 11 can be prevented from still driving the display screen 20 to move when locked, so that the driving assembly 11 is damaged, the service life of the driving mechanism 10 can be prolonged, and the use safety of a user is ensured.

Referring to fig. 2-5, in some embodiments, 04: the driving assembly 11 is controlled to drive the display screen 20 to move according to the target voltage and the real-time voltage output by the detecting piece 14, and the method comprises the following steps:

041: when the target voltage is smaller than the real-time voltage, the driving assembly 11 is controlled to drive the display screen 20 to move towards the direction of the first limit position;

043: in the case that the target voltage is equal to the real-time voltage, controlling the driving assembly 11 to stop working;

045: in the case that the target voltage is greater than the real-time voltage, the driving assembly 11 is controlled to drive the display screen 20 to move towards the direction where the second limit position is located.

Referring to fig. 3, the one or more processors 15 are capable of executing the methods 041, 043 and 045, that is, the one or more processors 15 are configured to control the driving assembly 11 to drive the display 20 to move toward the direction of the first limit position when the target voltage is less than the real-time voltage; in the case that the target voltage is equal to the real-time voltage, controlling the driving assembly 11 to stop working; in the case that the target voltage is greater than the real-time voltage, the driving assembly 11 is controlled to drive the display screen 20 to move towards the direction where the second limit position is located.

Specifically, as can be seen from the above embodiment, in the process of detecting whether the target voltage is greater than the current voltage, if the result of the analysis by the processor 15 is that the target voltage is not greater than the current voltage, that is, the target voltage is less than or equal to the real-time voltage, the processor 15 can analyze whether the target voltage is equal to the current voltage again, where when the processor 15 determines that the target voltage is less than the real-time voltage, the processor 15 can determine that the current position of the display screen 20 is closer to the second limit position than the position corresponding to the target voltage, thereby, the processor 15 can control the driving component 11 to drive the display screen 20 to move towards the direction of the first limit position, so that the display screen 20 can move to the position indicated by the operation command, and when the display screen 20 moves to the position indicated by the operation command, the target voltage is equal to the real-time voltage; when the result obtained by the analysis of the processor 15 is that the target voltage is equal to the real-time voltage, the processor 15 can determine that the current position of the display screen 20 is the position corresponding to the target voltage, in which case the driving assembly 11 does not need to drive the display screen 20 to move, in other words, the processor 15 can control the driving assembly 11 to stop working; if the result obtained by the analysis of the processor 15 is that the target voltage is greater than the real-time voltage, the processor 15 can determine that the current position of the display screen 20 is closer to the first limit position than the position corresponding to the target voltage, so that the processor 15 can control the driving assembly 11 to drive the display screen 20 to move towards the second limit position, so that the display screen 20 can move to the position indicated by the operation instruction, and when the display screen 20 moves to the position indicated by the operation instruction, the target voltage is equal to the real-time voltage.

If the driving element 111 in the driving element 11 fails or the display element 20 is blocked by an external force during the driving element 11 drives the display element 20 to move toward the first limit position or the second limit position, the driving element 11 is blocked, at this time, the driving element 11 cannot drive the display element 20 to rotate, but the driving element 111 still works normally, i.e. the rotation speed of the driving element 111 is 0, but still outputs torque, so that the driving element 111 will be damaged, and the use safety of the user will be affected. Specifically, referring to fig. 2 and 6, in some embodiments, detecting whether the driving assembly 11 is locked includes:

051: acquiring the current voltage of the driving assembly 11;

052: under the condition that the current voltage is larger than a preset voltage threshold value, confirming that the driving assembly 11 is locked;

053: in case the current voltage is less than or equal to the voltage threshold, it is confirmed that the driving assembly 11 is not locked.

Referring to fig. 3, the one or more processors 15 are capable of performing the methods 051, 052 and 053, i.e. the one or more processors 15 are used to obtain the current voltage of the driving assembly 11; under the condition that the current voltage is larger than a preset voltage threshold value, confirming that the driving assembly 11 is locked; in case the current voltage is less than or equal to the voltage threshold, it is confirmed that the driving assembly 11 is not locked.

Specifically, in some embodiments, the driving mechanism 10 may further include a sampling member 16, where the sampling member 16 is electrically connected to both the driving assembly 11 and the processor 15, and the sampling member 16 is capable of detecting the current of the driving assembly 11, converting the detected current signal into a voltage value, and outputting the voltage value to the processor 15. It should be noted that in some embodiments, the sampling member 16 may be a resistor or an element capable of detecting a voltage. Where the sampling member 16 is a resistor, the sampling member 16 can convert the current passing through the driving member 111 in the driving assembly 11 into a voltage value to be output as the current voltage of the driving assembly 11 to the processor 15.

More specifically, referring to fig. 4, in some embodiments, in a case where the driving assembly 11 drives the display screen 20 to move toward the first limit position or the second limit position, the processor 15 can obtain the current voltage of the driving assembly 11, that is, the processor 15 can obtain the current voltage of the driving member 111, where if the current voltage is greater than a preset voltage threshold, the current voltage of the driving member 111 is too high, and at this time, the driving member 111 is easy to be overloaded or damaged, so that the processor 15 can determine that the driving assembly 11 is locked; if the current voltage is less than or equal to the voltage threshold, the driving element 111 is still operating normally, and at this time, the processor 15 can determine that the driving assembly 11 is not locked, so that the processor 15 can analyze whether to control the driving assembly 11 to operate according to whether the driving assembly 11 is locked, thereby preventing the driving assembly 11 from being damaged, further ensuring the use safety of the user, and prolonging the service life of the driving assembly 11.

The preset voltage threshold may be a threshold value for determining whether the voltage of the driving component 11 is in a normal operation. The preset voltage frequency may be known data, which may be an empirical value obtained before the driving mechanism 10 leaves the factory, a set value manually input after the driving mechanism 10 leaves the factory, or an empirical value obtained by the processor 15 processing historical data after the driving mechanism 10 leaves the factory. For example, the preset voltage threshold may be 1V, and if the current voltage of the driving component 11 is less than or equal to 1V, the processor 15 can determine that the driving component 11 is not locked; if the current voltage of the drive assembly 11 is greater than 1V, the processor 15 can determine that the drive assembly 11 is locked.

Further, referring to fig. 2, 7 and 8, in some embodiments, detecting whether the driving assembly 11 is locked includes:

054: acquiring the current voltage of the driving assembly 11;

055: recording the times M when the current voltage is greater than a preset voltage threshold value in the process of driving the display screen 20 to move by the driving assembly 11; and

056: In case the recorded number M is greater than a preset number threshold, it is confirmed that the driving assembly 11 is locked.

Referring to fig. 3, the one or more processors 15 are capable of performing the methods of 055, 055 and 056, i.e., the one or more processors 15 are configured to obtain the current voltage of the drive assembly 11; recording the times M when the current voltage is greater than a preset voltage threshold value in the process of driving the display screen 20 to move by the driving assembly 11; and confirming that the driving assembly 11 is locked up in case that the recorded number of times M is greater than a preset number of times threshold.

Specifically, referring to fig. 4, in some embodiments, when the driving assembly 11 drives the display screen 20 to move toward the first limit position or the second limit position, the processor 15 can acquire data of the current voltage of the multiple driving assembly 11, that is, the processor 15 can acquire data of the current voltage of the multiple driving element 111, where if the current voltage acquired by the processor 15 is greater than a preset voltage threshold, the processor 15 can record the data of the multiple M, and at this time, the number of times M recorded by the processor 15 is 1; after that, the driving assembly 11 can still continue to drive the display screen 20 to move towards the first limit position or the second limit position, the processor 15 continues to acquire the current voltage of the driving assembly 11, if the current voltage acquired again by the processor 15 is still greater than the preset voltage threshold, the processor 15 can record again, at this time, the number of times M recorded by the processor 15 is 2, and under the condition that the steps of 053 and 054 are repeated by the processor 15 until the number of times M recorded by the processor 15 is greater than the preset number of times threshold, the processor 15 determines that the driving assembly 11 is blocked.

Since the current voltage of the driving component 11 may be occasionally greater than the preset voltage threshold during the movement of the display screen 20 by the driving component 11, for example, the voltage fluctuation of the power source for supplying power to the driving component 11 may affect the current voltage of the driving component 11, and when the power source voltage increases, the current voltage of the driving component 11 also increases; for another example, when the vehicle 100 is traveling on a rough road, the driving unit 11 may shake to generate a reverse resistance, and at this time, if the driving unit 11 is intended to normally drive the display 20 to rotate, the current voltage of the driving unit 11 will increase, and in these cases, the processor 15 will determine that the driving unit 11 is locked, however, the driving unit 11 at this time can still keep operating normally, and if the determination is made only according to the above conditions, erroneous determination is easily caused, resulting in poor intelligence of the driving mechanism 10. However, generally, if the driving assembly 11 is blocked, the current voltage of the driving assembly 11 should be always greater than the preset voltage threshold, so that, compared with the situation that the processor 15 only confirms that the driving assembly 11 is blocked when the current voltage is greater than the preset voltage threshold, the processor 15 confirms that the driving assembly 11 is blocked when the recorded number of times M is greater than the preset number of times threshold, so that the accuracy of the analysis result of the processor 15 can be improved, the processor 15 is prevented from misjudging to affect the normal operation of the driving assembly 11, and the intellectualization of the driving mechanism 10 is enhanced.

The preset frequency threshold may be known data, which may be an empirical value obtained before the driving mechanism 10 leaves the factory, a set value manually input after the driving mechanism 10 leaves the factory, or an empirical value obtained by the processor 15 processing historical data after the driving mechanism 10 leaves the factory. It should be noted that, in some embodiments, the preset number of times threshold may be any integer value greater than or equal to 2 times, 3 times, 4 times, 5 times, 6 times, and so on. For example, in the case where the preset number of times threshold is 4, the processor 15 confirms that the driving assembly 11 is locked in the case where the processor 15 records that the number of times M that the current voltage is greater than the preset voltage threshold is greater than 4, that is, in the case where the processor 15 records that the number of times M that the current voltage is greater than the preset voltage threshold is 5.

In some embodiments, the preset number of times threshold may be consecutive and adjacent ones of the current voltages of the multiple drive assembly 11 acquired by the processor 15. For example, the preset number of times threshold may be 3 times, and if the processor 15 records that the number of times M that the current voltage is greater than the preset voltage threshold is 4 times, the processor 15 confirms that the driving assembly 11 is locked. The number of times M that the current voltage is greater than the preset voltage threshold value may be recorded by the processor 15: the current voltage of the drive assembly 11 acquired by the processor 15 for the first time, the current voltage of the drive assembly 11 acquired by the processor 15 for the second time, the current voltage of the drive assembly 11 acquired by the processor 15 for the third time, and the current voltage of the drive assembly 11 acquired by the processor 15 for the fourth time. In other embodiments, the preset number of times threshold may be several times in succession and at intervals among the current voltages of the multiple drive assembly 11 acquired by the processor 15. For example, the preset number of times threshold may be 3 times, and if the processor 15 records that the number of times M that the current voltage is greater than the preset voltage threshold is 4 times, the processor 15 confirms that the driving assembly 11 is locked. The number of times M that the current voltage is greater than the preset voltage threshold value may be recorded by the processor 15: the current voltage of the drive assembly 11 acquired by the processor 15 for the first time, the current voltage of the drive assembly 11 acquired by the processor 15 for the third time, the current voltage of the drive assembly 11 acquired by the processor 15 for the fifth time, and the current voltage of the drive assembly 11 acquired by the processor 15 for the seventh time.

In some embodiments, the processor 15 may collect the current voltage of the drive assembly 11 at a rate of [10 ms/time, 50 ms/time ]. Specifically, in some embodiments, the collection rate of the current voltage of the driving component 11 by the processor 15 may be any one value or any value between any two values of 10 ms/time, 15 ms/time, 20 ms/time, 25 ms/time, 30 ms/time, 35 ms/time, 40 ms/time, 45 ms/time and 50 ms/time.

If the collection rate of the current voltage of the driving component 11 by the processor 15 is less than 10 ms/time, the collection rate of the current voltage of the driving component 11 by the processor 15 is too fast, so that the processor 15 needs to analyze and process the collected data more quickly, which results in excessive computational load of the processor 15, and further results in processing delay and even computational breakdown; if the collection rate of the current voltage of the driving component 11 by the processor 15 is greater than 50 ms/time, the collection rate of the current voltage of the driving component 11 by the processor 15 is too slow, so that the data collected by the processor 15 cannot reflect the actual change of the current voltage of the driving component 11, and the accuracy of the data processing of the processor 15 is poor. In the application, the collection rate of the processor 15 to the current voltage of the driving component 11 can be [10 ms/time, 50 ms/time ], so that on one hand, the excessive calculation load of the processor 15 caused by the too fast collection rate of the processor 15 to the current voltage of the driving component 11 can be prevented, and the working stability of the processor 15 is ensured; on the other hand, the data collected by the processor 15 can reflect the actual change of the current voltage of the driving assembly 11, so that the accuracy of the data processing of the processor 15 is improved.

Still further, referring to fig. 2 and 5, in some embodiments, detecting whether the driving assembly 11 is locked includes:

057: in the case of locked rotation of the driving assembly 11, controlling the driving assembly 11 to stop working; and/or

058: In case of a locked rotation of the drive assembly 11, a prompt message is issued.

Referring to fig. 3, the one or more processors 15 are capable of executing the methods of 057 and 058, i.e., the one or more processors 15 are configured to control the driving assembly 11 to stop working in case of a locked rotation of the driving assembly 11; and/or in case of a locked rotation of the drive assembly 11.

Specifically, in some embodiments, when the processor 15 determines that the driving assembly 11 is locked, the processor 15 can control the driving assembly 11 to stop working (for example, the processor 15 can control the external power supply to stop supplying power to the driving assembly 11), so that the current voltage of the driving assembly 11 is prevented from being too large to be damaged, and the use safety of a user is ensured. In other embodiments, the drive mechanism 10 may further include a reminder (not shown) that is electrically connected to the processor 15. In the event that the processor 15 determines that the drive assembly 11 is locked, the processor 15 can control the reminder to operate so that the reminder sends a reminder message to the user to alert the user that the drive assembly 11 is locked. The prompting piece comprises, but is not limited to, an indicator light, a loudspeaker, a buzzer, a vibration motor and the like. It should be noted that, when the user receives the prompt message, that is, when the user knows that the driving assembly 11 is locked, the user can send an instruction to the processor 15 to control the driving assembly 11 to stop working. In still other embodiments, the one or more processors 15 are further capable of performing the method of 059, i.e., the one or more processors 15 are further configured to control the drive assembly 11 to stop working and send a prompt message in the event of a locked-up of the drive assembly 11. Specifically, when the processor 15 determines that the driving assembly 11 is locked, the processor 15 can control the driving assembly 11 to stop working, and meanwhile, the processor 15 can also control the prompt to work so that the prompt sends prompt information to the user, thereby preventing misoperation of the user under the condition of unknowing and ensuring use safety of the user. It can be understood that in any case, if the processor 15 confirms that the driving assembly 11 is blocked, the processor 15 can execute the methods in steps 057, 058 and 059, so that the use safety of the user can be ensured, and the service life of the driving assembly 11 can be prolonged.

It will be appreciated that in some embodiments, after the driving assembly 11 is locked, and the processor 15 controls the driving assembly 11 to stop working and/or issue a prompt message, the user can issue an operation instruction for the display screen 20 again, at which time, the processor 15 can execute all the steps in the above embodiments again.

Since the mechanical resistance inside the driving mechanism 10 will become larger when the ambient temperature of the driving mechanism 10 is low, if the normal movement of the display screen 20 is still desired, the voltage of the driving component 11 needs to be increased, however, in the case that the voltage of the driving component 11 is increased to be greater than the preset voltage threshold, the processor 15 will determine that the driving component 11 is locked, but at this time, the current voltage of the driving component 11 needs to be kept greater than the preset voltage threshold by the user to ensure the movement of the display screen 20. In summary, if the preset voltage threshold is a constant value, the processor 15 is likely to misjudge, resulting in poor intelligence of the driving mechanism 10. Thus, in some embodiments, different ambient temperatures correspond to different voltage thresholds, with lower ambient temperatures corresponding to higher voltage thresholds. It should be noted that, in some embodiments, the voltage threshold may be 0.8V at an ambient temperature of-10 ℃; in the case of an ambient temperature of-20 ℃, the voltage threshold may be 1.0V; in the case of an ambient temperature of 10 ℃, the voltage threshold may be 0.5V.

Specifically, in some embodiments, the drive mechanism 10 may further include a temperature sensor 17, with the temperature sensor 17 being configured to detect an ambient temperature at which the drive mechanism 10 is located. Wherein the temperature sensor 17 can be communicatively coupled to the processor 15 to enable the processor 15 to obtain an ambient temperature detected by the temperature sensor 17 and adjust the voltage threshold based on the ambient temperature. The lower the ambient temperature of the driving mechanism 10 is, the higher the voltage threshold is, so that the driving assembly 11 can be prevented from being unable to increase the voltage to drive the display screen 20 to move when the ambient temperature of the driving mechanism 10 is lower, the accuracy of the analysis result of the processor 15 is improved, the processor 15 is prevented from misjudging to influence the normal operation of the driving assembly 11, and the intellectualization of the driving mechanism 10 is enhanced.

In other embodiments, different ambient temperature intervals correspond to different voltage thresholds, with lower ambient temperature intervals corresponding to higher voltage thresholds. It should be noted that, in some embodiments, the voltage threshold may be 0.5V where the ambient temperature is greater than 0 ℃; in the case where the ambient temperature is less than-15 ℃, the voltage threshold may be 1.0V; in the case of an ambient temperature of [ -15 ℃,0 ℃), the voltage threshold may be 0.8V.

Specifically, in some embodiments, the processor 15 is capable of acquiring the ambient temperature detected by the temperature sensor 17 and adjusting the voltage threshold according to the temperature interval in which the ambient temperature is located. The lower the environmental temperature interval where the driving mechanism 10 is located is, the higher the voltage threshold is, so that the driving assembly 11 can be prevented from being incapable of increasing the voltage to drive the display screen 20 to move when the environmental temperature where the driving mechanism 10 is located is lower, the accuracy of the analysis result of the processor 15 is improved, the processor 15 is prevented from misjudging to influence the normal operation of the driving assembly 11, and the intellectualization of the driving mechanism 10 is enhanced.

Since the driving mechanism 10 is easy to generate errors when the driving mechanism 10 is used for a long time, for example, errors occur in the detection of the deflection angle of the display screen 20 by the detecting element 13, and the errors can be increased continuously along with the time, so that the voltage output by the detecting element 13 is inconsistent with the actual voltage. Thus, referring to fig. 2, 9 and 10, in some embodiments, the control method further includes:

01: the driving mechanism 10 is controlled to perform an initializing operation.

Referring to fig. 3, one or more processors 15 are capable of performing the method of 01, i.e., the one or more processors 15 are configured to control the drive mechanism 10 to perform an initialization operation.

Specifically, in some embodiments, step 01 may be performed before step 02, that is, before the processor 15 obtains the operation instruction for the display screen 20, the processor 15 can control the driving mechanism 10 to perform the initialization operation, so as to implement calibration of the detection of the deflection angle of the display screen 20 by the detection member 13, and prevent the detection by the detection member 13 from generating an error, thereby ensuring accuracy of implementation of the operation instruction by the processor 15.

It should be noted that, in some embodiments, if step 01 is performed before step 02, the processor 15 can control the driving mechanism 10 to perform the initialization operation according to the initialization operation instruction output by the user. The initialization operation instruction is different from the "operation instruction for the display screen 20" in the above embodiment. The initialization command may be a voice control command, a touch control command, a non-touch control command, a remote control command, etc. issued by the user, which is not limited herein. For example, when the user needs to perform an initialization operation, the user can make a sound, such as speaking "perform initialization", in which case the processor 15 can acquire the sound of "perform initialization" made by the user and take the sound as an initialization operation instruction. Also for example, when the user needs to perform an initialization operation, the user can click a virtual key (for example, a key for "performing initialization") on the display screen 20, in which case the processor 15 can acquire a touch operation at the time of the virtual key clicked by the user and take the touch operation as an initialization operation instruction. For another example, when the user needs to perform the initialization operation, the user can send a remote control instruction to the display screen 20 through another device at a position distant from the display screen 20, in which case the processor 15 can acquire the remote control instruction and take it as the initialization operation instruction.

In other embodiments, step 01 may be performed after step 02 and before step 03, that is, after the processor 15 obtains the operation instruction for the display screen 20 and before the processor 15 obtains the target voltage of the detecting member 14 according to the operation instruction, the processor 15 can control the driving mechanism 10 to perform the initialization operation first, so as to implement calibration of the detecting member 13 for detecting the deflection angle of the display screen 20, prevent errors in detection of the detecting member 13, and ensure accuracy of implementation of the operation instruction by the processor 15. In the present embodiment, the processor 15 can control the driving mechanism 10 to perform the initializing operation in accordance with the operation instruction for the display screen 20 issued by the user.

Further, referring to fig. 2, 3, 4 and 10, in some embodiments, 01: controlling the driving mechanism 10 to perform an initialization operation includes:

011: the control driving assembly 11 drives the display screen 20 to move towards a first limit position;

014: acquiring a first voltage output by the detecting element 14 when the display screen 20 reaches a first limit position;

015: the control driving assembly 11 drives the display screen 20 to move towards the second limit position;

020: acquiring a second voltage output by the detecting element 14 when the display screen 20 reaches a second limit position;

021: acquiring a third voltage according to the first voltage and the second voltage; and

022: The driving assembly 11 is controlled to drive the display screen 20 to move towards the first limit position until the real-time voltage output by the detecting piece 14 is the third voltage.

Referring to fig. 3, the one or more processors 15 are capable of performing the methods 011, 014, 015, 020, 021 and 022, i.e. the one or more processors 15 are configured to control the driving assembly 11 to drive the display screen 20 towards the first extreme position; acquiring a first voltage output by the detecting element 14 when the display screen 20 reaches a first limit position; the control driving assembly 11 drives the display screen 20 to move towards the second limit position; in the case where the display screen 20 reaches the second limit position, the second voltage output by the detecting member 14; acquiring a third voltage according to the first voltage and the second voltage; and controlling the driving assembly 11 to drive the display screen 20 to move towards the first limit position until the real-time voltage output by the detecting piece 14 is the third voltage.

Specifically, in some embodiments, in a case where the processor 15 controls the driving assembly 11 to perform the initializing operation, the processor 15 can control the driving assembly 11 to drive the display screen 20 to move toward the first limit position, and in a case where the display screen 20 reaches the first limit position, obtain the first voltage output by the detecting element 13, where the first voltage is the reference voltage; subsequently, the processor 15 controls the driving assembly 11 to drive the display screen 20 to move from the first limit position to the second limit position, and obtains a second voltage output by the detecting element 13 when the display screen 20 reaches the second limit position, wherein the second voltage is a termination voltage; finally, the processor 15 can obtain a third voltage according to the first voltage and the second voltage, and control the driving assembly 11 to drive the display screen 20 to move towards the first limit position until the real-time voltage output by the detecting element 14 is the third voltage. It should be noted that, in some embodiments, the third voltage may be the first voltage, the second voltage, or any voltage between the first voltage and the second voltage. For example, in the case that the third voltage is half of the sum of the first voltage and the second voltage, the position corresponding to the third voltage is the center position between the first limit position and the second limit position, and in this case, the processor 15 can control the driving assembly 11 to drive the display screen 20 to move toward the first limit position, so that the real-time voltage output by the detecting element 14 is the third voltage, thereby completing the initialization operation of the driving mechanism 10.

In some embodiments, when the processor 15 controls the driving assembly 11 to drive the display screen 20 to move towards the first limit position or the second limit position, and the processor 15 needs to detect whether the driving assembly 11 is locked, and when the processor 15 confirms that the driving assembly 11 is locked, the processor 15 can execute the methods in steps 057, 058 and 059, so that the use safety of the user can be ensured, and the service life of the driving assembly 11 can be prolonged.

It can be understood that, in other embodiments, in the case that the processor 15 controls the driving assembly 11 to perform the initializing operation, the processor 15 can also control the driving assembly 11 to drive the display screen 20 to move toward the second limit position, and in the case that the display screen 20 reaches the second limit position, obtain the second voltage output by the detecting element 14; then, the driving assembly 11 is controlled to drive the display screen 20 to move towards the first limit position, and the first voltage output by the detecting piece 14 is obtained when the display screen 20 reaches the first limit position.

In some embodiments, the third voltage may be a voltage value that is preset and that can be used to determine whether the drive mechanism 10 has completed an initialization operation. The third voltage may be known data, or may be an empirical value obtained before the drive mechanism 10 comes out of the field, or may be a set value manually input after the drive mechanism 10 leaves the factory. In this embodiment, in the case that the processor 15 controls the driving assembly 11 to perform the initializing operation, the processor 15 can directly control the driving assembly 11 to drive the display screen 20 to move until the real-time voltage output by the detecting element 14 is equal to the third voltage, thereby completing the initializing operation.

Referring to fig. 2, 3, 4 and 11, in some embodiments, the control driving mechanism 10 performs an initialization operation, further includes:

012: detecting whether the driving assembly 11 is locked or not in the process that the driving assembly 11 drives the display screen 20 to move towards the first limit position;

0131: when the driving assembly 11 is not locked, and the limit switch 12 is closed, the display screen 20 is confirmed to reach the first limit position;

0133: in the case that the driving assembly 11 is not locked, and the limit switch 12 is not closed, the driving assembly 11 is controlled to drive the display screen 20 to move towards the first limit position.

Referring to fig. 3, the one or more processors 15 are capable of executing the methods 012, 0131, and 0133, i.e., the one or more processors 15 are configured to detect whether the driving assembly 11 is locked during the driving of the display 20 by the driving assembly 11 toward the first limit position; when the driving assembly 11 is not locked, and the limit switch 12 is closed, the display screen 20 is confirmed to reach the first limit position; in the case that the driving assembly 11 is not locked, and the limit switch 12 is not closed, the driving assembly 11 is controlled to drive the display screen 20 to move towards the first limit position.

The specific operation of "detecting whether the driving assembly 11 is blocked" in step 012 in the present embodiment is substantially identical to the specific operation of "detecting whether the driving assembly 11 is blocked" in step 05 in the above embodiment, and a detailed description thereof will not be repeated here. Specifically, in some embodiments, in the case where the processor 15 controls the driving assembly 11 to drive the display screen 20 to move toward the first limit position, if the processor 15 detects that the driving assembly 11 is not locked, and the limit switch 12 is closed, the processor 15 can determine that the display screen 20 reaches the first limit position, and in this case, the processor 15 can acquire the first voltage output by the detecting element 14; if the processor 15 detects that the drive assembly 11 is not locked and the limit switch 12 is not closed, it is indicative that the display screen 20 does not reach the first limit position, in which case the processor 15 can continue to control the drive assembly 11 to drive the display screen 20 towards the first limit position.

Referring to fig. 2, 3, 4 and 12, in some embodiments, the control driving mechanism 10 performs an initialization operation, further includes:

0135: in the case of a locked rotation of the drive assembly 11, the return execution control drive assembly 11 drives the display screen 20 to move toward the first limit position in accordance with a user input.

Referring to fig. 3, the one or more processors 15 are capable of executing the method in 0135, i.e. the one or more processors 15 are configured to control the drive assembly 11 to drive the display screen 20 towards the first extreme position in response to user input back to execute the control in case of a locked rotation of the drive assembly 11.

Specifically, in some embodiments, after the driving component 11 is locked, and the processor 15 controls the driving component 11 to stop working and/or send out prompt information, the user can input new instruction information, and the processor 15 can execute step 011 again according to the new instruction information output by the user, that is, the processor 15 can control the driving component 11 to drive the display screen 20 to move towards the first limit position again according to the new instruction information input by the user. For example, in the case where the new instruction information input by the user is "move again", the processor 15 can control the driving assembly 11 again to drive the display screen 20 to move toward the first limit position; when the new instruction information input by the user is "end", the processor 15 ends the present operation, and when the user does not input any new instruction information, the processor 15 can end the present operation. It can be appreciated that, if the processor 15 controls the driving assembly 11 to drive the display screen 20 to move toward the first limit position again, the processor 15 can control the driving assembly 11 to stop working and/or send out a prompt message again.

Referring to fig. 2, 3, 4 and 10, in some embodiments, the control driving mechanism 10 performs an initialization operation, and further includes:

016: in case the display 20 reaches the first limit position, a timer is started;

017: detecting whether the driving assembly 11 is blocked or not in the process that the driving assembly 11 drives the display screen 20 to move towards the second limit position;

0181: stopping timing and recording timing duration under the condition that the driving assembly 11 is blocked;

0191: if the time duration is greater than or equal to the preset time duration, confirming that the display screen 20 reaches the second limit position;

0193: in the case that the time duration is less than the preset time duration, confirming that the display screen 20 is still located between the first limit position and the second limit position; and

0183: In the case that the driving assembly 11 is not locked, the driving assembly 11 is continuously controlled to drive the display screen 20 to move towards the second limit position.

Referring to fig. 3, the one or more processors 15 are capable of executing the methods 016, 017, 0181, 0191, 0193 and 0183, i.e. the one or more processors 15 are adapted to start a timer in case the display 20 reaches the first limit position; detecting whether the driving assembly 11 is blocked or not in the process that the driving assembly 11 drives the display screen 20 to move towards the second limit position; stopping timing and recording timing duration under the condition that the driving assembly 11 is blocked; if the time duration is greater than or equal to the preset time duration, confirming that the display screen 20 reaches the second limit position; in the case that the time duration is less than the preset time duration, confirming that the display screen 20 is still located between the first limit position and the second limit position; and under the condition that the driving assembly 11 is not blocked, continuously controlling the driving assembly 11 to drive the display screen 20 to move towards the second limit position.

The specific operation of "detecting whether the driving assembly 11 is blocked" in the step 017 in the present embodiment is substantially identical to the specific operation of "detecting whether the driving assembly 11 is blocked" in the step 05 in the above embodiment, and the description thereof will not be repeated here.

Specifically, in certain embodiments, the drive mechanism 10 may also include a timer (not shown). When the processor 15 controls the driving assembly 11 to drive the display screen 20 to reach the first limit position and the driving assembly 11 starts to drive the display screen 20 to move towards the second limit position, the processor 15 controls the timer to start timing, and when the driving assembly 11 drives the display screen 20 to move towards the second limit position and the processor 15 confirms that the driving assembly 11 is blocked, the processor 15 controls the timer to stop timing and records the timing duration. If the processor 15 analyzes that the time period is greater than or equal to the preset time period, the display screen 20 is confirmed to reach the second limit position; if the processor 15 analyzes that the time duration is less than the preset time duration, it is determined that the display screen 20 is still located between the first limit position and the second limit position, that is, the processor 15 can determine that the display screen 20 is not located at the second limit position and the driving assembly 11 is locked, in which case the processor 15 can control the driving assembly 11 to stop working and/or send out a prompt message. In some embodiments, the time period is: the drive assembly 11 is controlled from the processor 15 to begin driving the display screen 20 from the first extreme position toward the second extreme position until the processor 15 confirms the total length of time it takes for the drive assembly 11 to lock.

In one embodiment, the initial data of the timer may be 0, that is, when the display 20 reaches the first limit position and the timer starts to count, the data of the timer is 0, in which case the processor 15 can directly acquire the data on the timer when the timer stops counting, that is, the counting duration. For example, when the timer stops counting, the data on the timer is 3 seconds, and then 3 seconds is the counting time length. In another embodiment, the initial data of the timer may not be 0, in which case, in the case where the timer stops counting, the processor 15 can acquire the difference between the data on the timer and the initial data of the timer, and take the difference as the counting duration. For example, when the initial data of the timer is 1s and the timer stops counting, the data on the timer is 5 seconds, the difference obtained by the processor 15 is 4 seconds, and at this time, 4 seconds is the counting time length.

The predetermined time period may be a minimum time period required by the processor 15 to control the driving assembly 11 to drive the display screen 20 to rotate from the first limit position to the second limit position. The preset time period may be known data, which may be an empirical value obtained before the driving mechanism 10 leaves the factory, a set value manually input after the driving mechanism 10 leaves the factory, or an empirical value obtained by the processor 15 processing historical data after the driving mechanism 10 leaves the factory. For example, the preset duration may be 3 seconds, and if the timed duration is greater than or equal to 3 seconds, the processor 15 confirms that the display 20 reaches the second limit position; in the event that the timed duration is less than 3 seconds, the processor 15 confirms that the display 20 is still between the first and second extreme positions, at which point the processor 15 can continue to control the drive assembly 11 to drive the display 20 toward the second extreme position.

Referring to fig. 2, 3, 4 and 13, in some embodiments, the control driving mechanism 10 performs an initialization operation, further includes:

0185: under the condition that the driving assembly 11 is blocked, acquiring the current voltage detected by the detecting piece 13;

0195: confirming that the display screen 20 reaches the second limit position when the current voltage is greater than or equal to the sum of the first voltage and a preset voltage variation threshold;

0197: in the case that the current voltage is less than the sum of the first voltage and the voltage variation threshold, confirming that the display screen 20 is still located between the first limit position and the second limit position;

Referring to fig. 3, the one or more processors 15 are capable of executing the methods 017, 0185, 0195, 0197 and 0183, i.e., the one or more processors 15 are configured to detect whether the driving assembly 11 is locked during the driving of the display 20 by the driving assembly 11 toward the second limit position; under the condition that the driving assembly 11 is blocked, acquiring the current voltage detected by the detecting piece 13; confirming that the display screen 20 reaches the second limit position when the current voltage is greater than or equal to the sum of the first voltage and a preset voltage variation threshold; in the case that the current voltage is less than the sum of the first voltage and the voltage variation threshold, confirming that the display screen 20 is still located between the first limit position and the second limit position; in the case that the driving assembly 11 is not locked, the driving assembly 11 is continuously controlled to drive the display screen 20 to move towards the second limit position.

Specifically, in some embodiments, in the case where the driving assembly 11 drives the display screen 20 to move toward the second limit position, and the processor 15 confirms that the driving assembly 11 is locked, the processor 15 acquires the current voltage detected by the detecting member 13; if the processor 15 analyzes that the current voltage is greater than or equal to the sum of the first voltage and the preset voltage variation threshold value, confirming that the display screen 20 reaches the second limit position; if the processor 15 analyzes that the current voltage is smaller than the sum of the first voltage and the voltage variation threshold, it is determined that the display screen 20 is still located between the first limit position and the second limit position, that is, the processor 15 can determine that the display screen 20 is not located at the second limit position and the driving assembly 11 is blocked, in which case the processor 15 can control the driving assembly 11 to stop working and/or send out a prompt message.

It should be noted that, in some embodiments, the preset voltage variation threshold may be a minimum variation of the voltage detected by the detecting element 14 when the processor 15 controls the driving assembly 11 to drive the display screen 20 to rotate from the first limit position to the second limit position. The preset voltage variation threshold may be known data, which may be an empirical value obtained before the driving mechanism 10 leaves the factory, a set value manually input after the driving mechanism 10 leaves the factory, or an empirical value obtained by the processor 15 processing historical data after the driving mechanism 10 leaves the factory.

Referring to fig. 2, 3 and 14, in some embodiments, the control method further includes:

07: acquiring the current ambient temperature of the drive assembly 11;

08: recording the number N of strokes when the current ambient temperature is greater than a preset temperature threshold value in the process of driving the display screen 20 to move by the driving assembly 11; and

09: Controlling the driving assembly 11 to stop working under the condition that the recorded number N of strokes is larger than a preset threshold value of strokes; and/or issue a prompt.

Referring to fig. 3, the one or more processors 15 are capable of executing the methods 07, 08 and 09, i.e., the one or more processors 15 are configured to obtain the current ambient temperature of the drive assembly 11; recording the number N of strokes when the current ambient temperature is greater than a preset temperature threshold value in the process of driving the display screen 20 to move by the driving assembly 11; and controlling the driving assembly 11 to stop working under the condition that the recorded number N of strokes is larger than a preset threshold value of strokes; and/or issue a prompt.

Since the high temperature may cause the driving assembly 11 to burn out or increase the power consumption of the driving assembly 11 when the environmental temperature of the driving assembly 11 is too high, in the present application, when the driving assembly 11 drives the display screen 20 to move toward the first limit position or the second limit position, the processor 15 can acquire the data detected by the temperature sensor 17 (the current environmental temperature of the driving assembly 11) multiple times, wherein if the current environmental temperature acquired by the processor 15 is greater than the preset temperature threshold, the processor 15 can record the data M multiple times, and at this time, the number N of times recorded by the processor 15 is 1; afterwards, the driving assembly 11 can still work normally, that is, the driving assembly 11 can still drive the display screen 20 to move towards the first limit position or the second limit position, the processor 15 continues to acquire the data detected by the temperature sensor 17, if the current ambient temperature acquired by the processor 15 again is greater than the preset temperature threshold value, the processor 15 can record again, at this time, the number of strokes N recorded by the processor 15 is 2, and under the condition that the steps of 07 and 08 are repeated by the processor 15 until the recorded number of strokes N is greater than the preset number of strokes threshold value, the processor 15 controls the driving assembly 11 to stop working; and/or issue a prompt.

In some embodiments, when the recorded number of strokes N is greater than the preset threshold, and the controller controls the driving component 11 to stop working, the controller can also control a prompting piece (not shown) to send a prompting message, so that the user knows that the driving component 11 stops working due to the excessive temperature. In addition, in some embodiments, when the recorded number of strokes N is greater than the preset threshold, and the duration of time that the controller controls the driving assembly 11 to stop working is greater than the predetermined duration, the controller controls the driving assembly 11 to start. For example, the predetermined time period may be 3 minutes, and the controller may control the driving assembly 11 to be started when the recorded number of strokes N is greater than a preset threshold number of strokes and the time period during which the controller controls the driving assembly 11 to stop operating is greater than 3 minutes.

The preset threshold value may be known data, which may be an empirical value obtained before the driving mechanism 10 leaves the factory, a set value manually input after the driving mechanism 10 leaves the factory, or an empirical value obtained by the processor 15 processing historical data after the driving mechanism 10 leaves the factory. It should be noted that, in some embodiments, the preset threshold may be any integer value such as 1,2,3,4, 5, and 6 times. For example, in the case that the preset threshold number of strokes is 4 times, the processor 15 controls the driving assembly 11 to stop working in the case that the processor 15 records that the current ambient temperature is greater than the preset threshold number of strokes N is greater than 4 times, that is, in the case that the processor 15 records that the current ambient temperature is greater than the preset threshold number of strokes N is 5 times.
