The sliding seat 102 has a first end surface 102a and a second end surface 102b which are opposite to each other.

The application processor mainly processes an operating system, a user interface, application programs and the like, and the baseband processor mainly processes wireless communication. It will be appreciated that the baseband processor described above may not be integrated into the processor.

The memory 104 may be used for storing software programs and modules, and the processor 103 executes various functional applications and data processing of the electronic device 100 by operating the software programs and modules stored in the memory 104. The memory 104 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program required for at least one function, and the like; the storage data area may store data created according to use of the electronic device, and the like. Further, the memory 104 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

In one possible example, the at least one control parameter range includes a first control parameter range, a second control parameter range, and a third control parameter range, where a total stroke corresponding to a first stroke, a second stroke, and a third stroke is a maximum stroke of the sliding seat 102, the first stroke includes an initial position of the maximum stroke in the current sliding direction of the sliding seat 102, the third stroke includes an end position of the maximum stroke in the current sliding direction of the sliding seat 102, the first stroke is a stroke corresponding to the first control parameter range, the second stroke is a stroke corresponding to the second control parameter range, and the third stroke is a stroke corresponding to the third control parameter range;

the first speed corresponding to the first control parameter range is greater than the third speed corresponding to the third control parameter range and is less than the second speed corresponding to the second control parameter range.

In this possible example, in the aspect of controlling the driving mechanism 105 to drive the sliding seat 102 to slide at the target speed according to the target speed description information, the processor 103 is specifically configured to: when the target control parameter range is the third control parameter range, controlling the driving mechanism 105 to drive the sliding seat 102 to slide according to the third speed; and is used for detecting the actual position of the sliding seat 102 when the sliding seat 102 is determined to be at a first target position through the current value of the control parameter, wherein the first target position is a position where the sliding seat 102 corresponding to the control instruction stops sliding; and is used for controlling the driving mechanism 105 to drive the sliding seat 102 to slide from the actual position to the first target position when the actual position is detected to be different from the first target position.

In this possible example, the electronic device 100 further comprises a target sensor 107, and in terms of the detection of the actual position of the sliding seat 102, the processor 103 is specifically configured to: detecting a reference value of a target sensor 107, the target sensor 107 being any one of: a Hall sensor, an infrared sensor; and for determining the actual position of the slide shoe from the reference value.

Referring to fig. 2, fig. 2 is a schematic flow chart of a speed control method according to an embodiment of the present application, applied to the electronic device shown in fig. 1A-1C, the electronic device including a sliding seat and a driving mechanism, as shown in the figure, the speed control method includes:

s201, when detecting a control instruction for the sliding seat, the electronic device obtains at least one control parameter range for the driving mechanism according to the control instruction, wherein each control parameter range is a value set of the control parameter corresponding to a preset stroke in advance, the preset stroke is a part or all of the stroke of the sliding seat, and different control parameter ranges correspond to different preset strokes;

wherein, the sliding seat comprises a plurality of functional devices, such as any one or more of the following: the control instruction for the sliding seat may be a control instruction for different functional devices in the plurality of functional devices, for example, a control instruction for a camera module in the plurality of functional devices, such as a shooting start instruction or a video start instruction corresponding to a plurality of application programs, a control instruction for a receiver module in the plurality of functional devices, such as a call instruction for a telephone application, or a voice receiving instruction corresponding to a chat-type interactive application, and the like, which is not limited herein.

For example, the plurality of functional devices corresponding to the video call starting instruction for the chat interactive application are respectively a camera module and a receiver module, and for example, the functional device corresponding to the starting instruction for the camera application may be a camera module.

The control parameter is a control parameter for controlling the driving mechanism to drive the sliding seat by the electronic device, for example, the number of steps of the stepping motor in the driving mechanism or the number of cycles of the stepping motor, and is not limited herein.

The number of the control parameter ranges corresponding to different control instructions is different, for example, the control instruction is a control instruction for a camera module, the sliding seat needs to slide out of the accommodating groove of the middle frame, so that 3 control parameter ranges can be set to correspond to 3 sections of preset strokes respectively, or the control instruction is a control instruction for a receiver, a small part of the sliding seat needs to slide out of the accommodating groove of the middle frame, so that one control parameter range can be set to correspond to 1 section of preset strokes, therefore, the number of the control parameter ranges corresponding to different control instructions is flexible and changeable, and is not limited herein.

S202, the electronic device determines a current numerical value of the control parameter and determines a target control parameter range to which the current numerical value belongs;

if the control parameter is the number of steps of the stepping motor, the current numerical value is the number of steps currently rotated by the stepping motor, and if the control parameter is the number of cycles, the current numerical value is the total number of control pulses correspondingly sent to the stepping motor when the driving mechanism drives the sliding seat to the current position.

S203, the electronic device controls the driving mechanism to drive the sliding seat to slide at a target speed according to target speed description information, wherein the target speed description information is speed description information corresponding to the target control parameter range, and the speed description information is used for representing the speed of the preset stroke corresponding to the control parameter range;

the electronic device is preset with a mapping relation between the control parameter range and the speed, and the speed is the speed at which the electronic device controls the driving mechanism to drive the sliding seat to slide.

In one possible example, the at least one control parameter range includes a first control parameter range, a second control parameter range, and a third control parameter range, where a total stroke corresponding to a first stroke, a second stroke, and a third stroke is a maximum stroke of the sliding seat, the first stroke includes an initial position of the maximum stroke in the current sliding direction of the sliding seat, the third stroke includes an end position of the maximum stroke in the current sliding direction of the sliding seat, the first stroke is a stroke corresponding to the first control parameter range, the second stroke is a stroke corresponding to the second control parameter range, and the third stroke is a stroke corresponding to the third control parameter range;

The maximum stroke of the sliding seat corresponds to the maximum length of a screw rod in the driving mechanism, namely the farthest distance that the sliding seat can extend out of the accommodating groove of the middle frame.

The sliding seat is provided with a sliding seat, a middle frame and a sliding seat, wherein different control instructions correspond to different sliding directions of the sliding seat relative to the middle frame, and a first control parameter range, a second control parameter range and a third control parameter range which correspond to different sliding directions are different; if the current sliding direction of the sliding seat is the direction that the sliding seat tends to the middle frame and retracts into the accommodating groove, the ending position is the position that the sliding seat is completely accommodated in the accommodating groove of the middle frame, and the initial position is the farthest position on the sliding stroke of the sliding seat opposite to the ending position.

For example, the total stroke of the screw rod is 8.5mm, the sliding direction is the direction in which the sliding seat is far away from the middle frame and extends out of the accommodating groove, then the first control parameter range is the control parameter range corresponding to the first stroke (0-0.5mm), the first speed is 1000pps, the second control parameter range is the control parameter range corresponding to the second stroke (0.5mm-7.5mm), the second speed is 2500pps, the third control parameter range is the control parameter range corresponding to the third stroke (7.5mm-8.5mm), and the third speed is 50pps, where unit pps represents the number of pulses per second.

Taking the first stroke as an example, the sliding distance is 0.5mm, the pitch of the stepping motor in the driving mechanism is 2.4mm, the gear box transmission ratio in the stepping motor is 18.06, and the number of turns of the stepping motor is 0.5/(2.4 × 18.06), wherein the stepping motor makes 20 turns, each turn corresponds to 32 cycles inside the motor, the angular speed of the driving mechanism is 2 pi/20 × 32, and the sliding distance corresponding to the sliding seat sliding first stroke corresponds to the first control parameter range, namely, the cycle number is N ═ 0.5/(2.4 × 18.06) ] [2 pi/(2 pi/20 × 32) ] [0.5/(2.4 × 18.06) ] (20 × 32).

It can be seen that, in this example, the electronic device sets the control parameter ranges to three control parameter ranges, and sets the first speed of the stroke including the initial position to a speed value smaller than the second speed and greater than the third speed, so as to ensure that the driving mechanism has sufficient starting force when initially driving the sliding seat, which is beneficial to ensuring the normal operation of the motor, and sets the middle stroke to the second speed, i.e. the maximum speed can ensure that the total sliding duration of the sliding block is within a shorter duration range, which is beneficial to shortening the sliding duration and increasing the sliding speed, and sets the third speed of the stroke including the end position to the minimum speed, thereby avoiding that the sliding seat and the middle frame collide with each other more strongly when sliding to the end position, reducing the loss of devices, and reducing noise.

In this possible example, the controlling the driving mechanism to drive the sliding seat to slide at the target speed according to the target speed description information includes:

when the target control parameter range is the third control parameter range, controlling the driving mechanism to drive the sliding seat to slide according to the third speed;

when the sliding seat is determined to be at a first target position through the current numerical value of the control parameter, detecting the actual position of the sliding seat, wherein the first target position is a position, corresponding to the control instruction, at which the sliding seat stops sliding;

when the actual position is detected to be different from the first target position, controlling the driving mechanism to drive the sliding seat to slide from the actual position to the first target position.

Different control commands correspond to different sliding seat sliding stopping positions, and different control commands correspond to different started functional devices, so that the sliding seats need to slide out at different distances, and the sliding seat sliding stopping positions are different.

The specific implementation manner of detecting the actual position of the sliding seat by the electronic device may be various, for example, the distance between the sliding seat and the middle frame may be obtained by an infrared sensor or a proximity sensor mounted on the middle frame or the sliding seat, so as to determine the actual position of the sliding seat; or the position of the sliding seat may be changed by changing the magnetic flux of the magnetic field through a hall sensor mounted on the middle frame and a magnet mounted on the extension portion of the sliding seat, and the actual position of the sliding seat may be determined by reading the value of the hall sensor, which is not limited herein.

The control time length for controlling the driving device by the electronic device is set for the first target position, and the control time length can enable the driving device to control the sliding seat to accurately reach the first target position, but the step loss phenomenon can occur in the rotating process of the stepping motor in the driving device, so that the control time length of the electronic device is short, and the sliding seat cannot reach the first target position, namely the actual position is different from the target position.

The specific implementation manner of the electronic device controlling the driving mechanism to drive the sliding seat to slide from the actual position to the first target position may be various, for example, the control duration may be determined again first, and the sliding seat is controlled to reach the target position according to the control duration, or the actual position may be detected in parallel during the driving of the sliding seat by the driving mechanism, and when it is detected that the actual position is the same as the first target position, the driving mechanism is stopped being controlled to drive the sliding seat.

Therefore, in the example, when the electronic device controls the driving mechanism to move the sliding seat to the first target position, the electronic device detects the actual position where the sliding seat arrives, and when the actual position is different from the target position, the electronic device controls the driving mechanism, so that the phenomenon of step loss of the motor is effectively avoided, and the accuracy of the position where the sliding seat stops sliding is ensured.

In this possible example, said detecting the actual position of said sliding seat comprises

Detecting a reference value of a target sensor, wherein the target sensor is any one of the following: a Hall sensor, an infrared sensor;

determining the actual position of the sliding seat according to the reference value.

The target sensor may be one or more sensors of any one of the sensors, which is not limited herein, and different sensors or different numbers of sensors correspond to different reference values, for example, when the target sensor is one hall sensor, the reference value is a value fed back by the hall sensor, and when the target sensor is two hall sensors, the reference value may be a difference between values fed back by the two hall sensors, which is not limited herein.

The specific implementation manner of determining the actual position of the sliding seat according to the reference value may be that the actual position is determined according to a mapping relationship between pre-stored reference values and positions, different reference values correspond to different mapping relationships, and the pre-stored mapping relationship is determined by a technical developer before the electronic device leaves a factory, according with the mapping relationship of each electronic device, by testing numerical values of the sensor at different positions of the sliding seat.

It can be seen that, in this example, after the electronic device is driven by the driving mechanism, the current actual position is detected by the target sensor to determine whether the motor has a step loss phenomenon, which is beneficial to ensuring that the sliding seat can reach the first target position when the driving is completed, so that the accuracy of the driving control is improved.

In one possible example, the method further comprises:

when the target control parameter range is in the first control parameter range or the second control parameter range and the speed of the driving mechanism driving the sliding seat to slide is detected to be smaller than a preset speed threshold value, executing a first operation and a second operation in parallel, wherein the first operation is displaying a prompt message blocked by an obstacle, and the second operation is controlling the driving mechanism to stop driving the sliding seat to slide.

The preset speed threshold is an empirical value, and is preset in the electronic device by a technical developer before the electronic device leaves a factory, where the preset speed threshold may include one or two, and when the preset speed threshold is one, for example, 900pps, 800pps, and the like, and when the preset speed threshold is two, the preset speed threshold may correspond to different control parameter ranges, for example, the preset speed threshold corresponding to the first control parameter range is 900pps, and the preset speed threshold corresponding to the second control parameter range is 2000pps, and the like, and is not limited herein.

It can be seen that, in this example, the electronic device detects that the drive mechanism drives the gliding speed of sliding seat is less than preset speed threshold, when speed is not conform to the speed under the electronic device control promptly, it shelters from to confirm that there is the barrier, for example can be people's hand, object etc., remind the user when the barrier shelters from, the user can remove the barrier according to the suggestion message, be favorable to indicateing drive control's intelligence, stop to drive the sliding seat simultaneously and slide, be favorable to avoiding sliding by force under the barrier condition and leading to mechanical damage, in addition, carry out first operation and second operation in parallel and effectively reduced serial operation's duration, promote control speed.

In one possible example, the method further comprises:

when the position of the sliding seat is detected not to be at the second target position, acquiring the acceleration of the electronic device;

and when the electronic device is determined to be in a falling state according to the acceleration, controlling the driving mechanism to drive the sliding seat to slide to the second target position.

The second target position is a position when the sliding seat is completely accommodated in the accommodating groove, and the specific implementation manner of determining that the electronic device is in the falling state according to the acceleration may be that the acceleration of the electronic device is detected to be suddenly changed and the changed acceleration lasts for a preset duration, or may be that the acceleration of the gravity acceleration of the electronic device is detected to be suddenly changed and the changed acceleration lasts for a preset duration, which is not limited herein.

Therefore, in the example, when the electronic device is not completely accommodated in the accommodating groove at the position of the sliding seat, the acceleration of the electronic device is monitored, and when the electronic device is determined to be in a falling state through the acceleration, the sliding seat is immediately and completely accommodated in the accommodating groove, so that the damage degree of the sliding seat in the falling process is reduced.
