[0032] Embodiment 1

[0033] The flip screen is connected to the output end of the drive motor. The drive motor outputs torque to drive the flip screen to open or close. During this process, there are certain safety hazards. For example, it may cause harm to the user during the opening or closing process. Therefore, most existing flip screens are provided with an anti-pinch control mechanism. In the prior art, the anti-pinch control method for the flip screen is: preset a fixed current threshold, obtain the real-time drive current of the drive motor, and determine whether there is a stall during the current flip process by comparing the real-time drive current of the drive motor with the current threshold. If it is determined that there is a stall, the anti-pinch mechanism is triggered. This control method in the prior art is simple to implement, but in actual applications, in order to take into account image factors such as product differences, environmental temperature, bumpy road conditions, and gravity forces at different angles, the current threshold is often set relatively large, which will result in too large anti-pinch force for the flip screen, and there are large differences in anti-pinch forces among different products, which also poses safety hazards. In this regard, please refer to Figure 1 , the embodiments of the present application provide an anti-pinch control method for a flip screen, including: steps S110 to S140.

[0034] Step S110, obtain the actual current from the motor driver, where the actual current is used to control the drive motor to output a first torque to drive the flip screen to flip in a first direction.

[0035] In this embodiment, the output end of the driving motor is connected to the flipping screen, and the actual current is used to control the driving motor to output a first torque to drive the flipping screen to flip in a first direction, where the first direction is the clockwise direction or the counterclockwise direction centered on one end of the flipping screen.

[0036] It should be noted that the actual current used to control the output torque of the driving motor is specifically obtained from the motor driver, or obtained through a current sensor, or obtained through other means according to the actual situation. The actual current in this application is the actual consumption current of the driving motor. The magnitude of the current value of the actual current is positively correlated with the current load of the driving motor. The greater the load, the greater the actual current; the smaller the load, the smaller the actual current.

[0037] In one embodiment, please refer to Figure 2 , before obtaining the actual current from the motor driver, it further includes: step S100.

[0038] Step S100, monitor the flipping speed of the flipping screen, and determine whether to obtain the actual current according to the flipping speed.

[0039] In this embodiment, the flipping speed of the flipping screen can be measured by a Hall sensor. It can be understood that when the flipping speed of the flipping screen abnormally decreases or the flipping stops during the flipping process, it can be considered that there may be an obstacle during the current flipping process. At this time, it is necessary to obtain the actual current and further determine according to the actual current.

[0040] In one embodiment, determining whether to obtain the actual current according to the flipping speed includes: determining whether the flipping speed is less than or equal to a preset flipping speed. If so, it is determined to obtain the actual current.

[0041] In this embodiment, when the flipping speed is less than or equal to the preset flipping speed, it can be determined that the current flipping process is abnormal. Further, obtain the actual current to determine whether it is necessary to trigger the anti-pinch mechanism of the flipping screen.

[0042] Step S120, determine the base current according to the actual current.

[0043] In this embodiment, the base current is the minimum current value required for the driving motor to drive the flipping screen to flip normally. The actual current is the current actually consumed when the driving motor drives the screen to flip. When the screen flips normally, the base current will follow the actual current, that is, the base current ≈ the actual current; when the screen flipping is abnormal, such as stalling, the actual current will mutate. At this time, there is a difference between the actual current and the base current. Specifically, the base current is obtained by filtering the actual current, filtering the mutated part in the actual current to resist the influence brought by the current mutation.

[0044] It can be understood that the base current determined according to the actual current can maintain the minimum current value required for the normal flipping of the flipping screen.

[0045] In one embodiment, determining the base current according to the actual current includes: performing filtering processing on the actual current by using a preset filtering algorithm to obtain the base current.

[0046] In this embodiment, please refer to Figure 3 , Figure 3 , which shows a schematic diagram of the actual current and the base current described in the embodiment of the present application. In the figure, the line Iq represents the actual current, and the line Iq_basic represents the base current obtained after filtering the actual current. It can be seen from the figure that in the present application, the base current follows the actual current but resists the influence caused by the current mutation in the actual current.

[0047] By comparing the current difference between the actual current and the base current, it can be determined whether an abnormality occurs in the current flipping process of the flipping screen. It can be understood that the base current represents the minimum current value required for the driving motor when the flipping screen flips normally. Therefore, under normal circumstances, the actual current should be close to the base current. If the current difference between the actual current and the base current meets the preset current condition, it is determined that an abnormality occurs in the flipping at this time.

[0048] Step S130, determining whether the actual current and the base current meet the preset current condition.

[0049] In this embodiment, if the actual current and the base current meet the preset current condition, it can be determined that the current flipping is abnormal at this time, and the anti-pinch mechanism is further triggered. Otherwise, it is determined that the current flipping is normal, and the flipping continues to the preset target position.

[0050] In one embodiment, please refer to Figure 4 , step S130 includes: steps S131 to S134.

[0051] Step S131, determining the current difference according to the actual current and the base current.

[0052] In this embodiment, please refer to again Figure 3 , Figure 3 in, the line Iq_target represents the target current, where Iq_target = |Iq - Iq_basic|, that is, Figure 3 the target current in represents the current difference between the actual current and the base current.

[0053] Step S132, if the current difference is greater than the preset current value, record the duration for which the current difference is greater than the preset current value.

[0054] In this embodiment, if the current difference is greater than the preset current value, the duration during which the current difference is greater than the preset current value is recorded, and further, it is determined whether to trigger the anti-pinch mechanism according to the duration. Figure 3 The preset current value is not shown.

[0055] In one embodiment, the method further includes: if the current difference is less than or equal to the preset current difference, it is determined that the actual current and the base current do not meet the preset current condition.

[0056] In this embodiment, if the current difference is less than or equal to the preset current difference, it is determined that the actual current and the base current do not meet the preset current condition, that is, the current flipping process is normal, and the driving motor drives the flipping screen to continue flipping.

[0057] Step S133, determine whether the duration is greater than the preset time threshold. If so, it is determined that the actual current and the base current meet the preset current condition.

[0058] It can be understood that if the actual current continuously exceeds the base current by more than the preset time threshold, for example, 50 ms, it can be determined that the current flipping process is abnormal, and then the anti-pinch mechanism is triggered.

[0059] Compared with the prior art, in which it is determined whether to trigger the anti-pinch mechanism according to the difference between the actual current and a fixed preset current threshold, the judgment accuracy of this application by monitoring the difference between the actual current and the base current is higher. Since the base current changes with the change of the actual current, and the magnitude of the actual current is affected by the load size and changes, when the load changes suddenly, by comparing the difference between the actual current and the base current, it can be quickly determined whether the current flipping is abnormal, and then the anti-pinch mechanism is triggered.

[0060] It can be understood that in this judgment method in the prior art, since the preset current threshold is fixed, and in order to take into account influencing factors such as product differences, environmental temperature, bumpy road conditions, and gravity forces at different angles, the preset current threshold is generally set relatively large. When the load changes suddenly, the actual current changes suddenly, but the mutated actual current is still less than the preset current threshold. At this time, the flipping screen will continue to flip, causing the actual current to continue to increase until it is greater than the preset current threshold, and then the anti-pinch mechanism is triggered. In the prior art, in order to ensure the judgment consistency of different products, the preset current threshold is set relatively large, which will lead to an excessive anti-pinch torque, and thus pose a safety hazard. However, this control method in this application improves the control accuracy and avoids the problem of excessive anti-pinch torque.

[0061] Step S134, if not, it is determined that the actual current and the base current do not meet the preset current condition.

[0062] In this embodiment, if the duration is less than or equal to a preset time threshold, it is determined that the actual current and the base current do not meet the preset current condition.

[0063] Step S140, if so, control the flip screen to flip in the second direction, where the second direction is opposite to the first direction.

[0064] In this embodiment, if the first direction is the clockwise direction, the second direction is the counterclockwise direction; if the first direction is the counterclockwise direction, the second direction is the clockwise direction. It can be understood that when the actual current and the base current meet the preset current condition, the anti-pinch mechanism is triggered, which specifically includes: sending an anti-pinch signal to the drive motor so that the drive motor outputs a second torque, and driving the flip screen to change the flipping direction to achieve anti-pinch.

[0065] In one embodiment, the controlling the flip screen to flip in the second direction includes: sending an anti-pinch signal to the drive motor to control the drive motor to output a second torque, and driving the flip screen to flip to a preset position in the second direction.

[0066] In this embodiment, for example, if an abnormality occurs during the clockwise flipping of the flip screen, an anti-pinch signal is sent to the drive motor. When the anti-pinch signal is received, the drive motor first stops outputting the first torque to control the flip screen to flip clockwise, and then changes the torque output direction to output a second torque to control the flip screen to flip counterclockwise.

[0067] The flip screen anti-pinch control method provided by the embodiment of the present application obtains the actual current from the motor driver, where the actual current is used to control the drive motor to output a first torque to drive the flip screen to flip in the first direction; determines the base current according to the actual current; determines whether the actual current and the base current meet the preset current condition; if so, controls the flip screen to flip in the second direction, where the second direction is opposite to the first direction, improving the anti-pinch control accuracy of the flip screen, reducing the anti-pinch torque of the flip screen, and further improving the safety performance of the flip screen.
