The following describes the method for preventing electromagnetic interference of the sliding assembly and the driving assembly according to the embodiments of the present invention with reference to the accompanying drawings.

In order to describe the speed change method for preventing electromagnetic interference according to the embodiment of the present invention more clearly, the following first describes the structure of the electronic device of the present invention.

Specifically, in order to reduce the influence on the screen ratio of the hardware devices such as the front camera installed on the front panel of the electronic device, the present invention proposes a sliding component, which controls the front camera when needed by sliding the sliding component. It slides out and is accommodated in the main body of the electronic device when not needed, so that it does not occupy the front panel of the electronic device when the functional services of components such as the front camera are not performed.

Specifically, as shown in FIGS. 1 to 4 , the electronic device 100 according to the embodiment of the present invention includes a body 10 , a sliding component 20 and a driving component 50 . The sliding assembly 20 is used for sliding between a first position A accommodated in the body 10 and a second position B exposed from the body 10 . The driving assembly 50 is used for driving the sliding assembly 20 to slide between a first position accommodated in the body and a second position exposed from the body.

Of course, in order for the driving assembly 50 to know the driving sliding assembly 20 to slide to a corresponding position, the electronic device must also include a detection assembly 30 for detecting the current position of the sliding assembly 20. In the embodiment of the present invention, the detection assembly 30 is used to detect sliding The position of the assembly 20, the detection assembly 30 includes a magnetic field generating element 32, a Hall element 34 and a processor 36, the magnetic field generating element 32 and the Hall element 34 are respectively fixed on the body 10 and the sliding assembly 20, and the processor 36 is used to receive the Hall element 36. The detection signal value output by the element 34 is used to determine the current relative position of the sliding assembly 20 relative to the body 10 according to the detection signal value.

It is worth noting that here "the magnetic field generating element 32 and the Hall element 34 are respectively fixed on the body 10 and the sliding assembly 20" includes two cases, one is that the magnetic field generating element 32 is fixed on the body 10, and the Hall element 34 is fixed On the sliding assembly 20 , secondly, the magnetic field generating element 32 is fixed on the sliding assembly 20 , and the Hall element 34 is fixed on the body 10 . In addition, the magnetic field generating element 32 and the Hall element 34 may be placed opposite to each other in the vertical direction, and may also be placed opposite to each other in the horizontal direction. That is to say, as long as the magnetic field generating element 32 and the Hall element 34 can generate relative motion, the specific positions of the magnetic field generating element 32 and the Hall element 34 are not limited.

In some embodiments, the body 10 is formed with a chute 16 , and the sliding assembly 20 is accommodated in the chute 16 when the first position A is located. In this way, the sliding assembly 20 can be slid between the first position A and the second position B through the sliding groove 16 .

Specifically, the body 10 includes a casing 12 and a display assembly 14, and the casing 12 and the display assembly 14 are combined together to form a closed structure. The chute 16 is opened in the housing 12 so as to realize the sliding back and the sliding out of the sliding assembly 20 . It can be understood that the chute 16 can be provided on any side of the housing 12 . Preferably, the chute 16 is opened on the top edge of the housing 12 . This can conform to the user's usage habits.

The display assembly 14 includes a touch panel (not shown) and a cover 142 . The touch panel includes a display module (not shown) and a touch layer (not shown) disposed on the display module. The display module is, for example, a liquid crystal display module (LCD Module, LCM). Of course, the display module can also be a flexible display module. The touch layer is used for receiving a user's touch input to generate a signal for controlling the content displayed by the display module and a signal for controlling the sliding of the sliding component 20 .

The material of the cover plate 142 may be made of transparent materials such as glass, ceramics or sapphire. Since the cover plate 142 is an input part of the electronic device 100, the cover plate 142 is often subjected to contact such as bumps or scratches. For example, when a user puts the electronic device 100 into a pocket, the cover 142 may be scratched and damaged by a key in the user's pocket. Therefore, the material of the cover plate 142 may be a material with relatively high hardness, such as the above sapphire material. Alternatively, a hardened layer may be formed on the surface of the cover plate 142 to improve the scratch resistance of the cover plate 142 .

The touch panel and the cover 142 are bonded and fixed together by, for example, Optical Clear Adhesive (OCA). The optical adhesive not only bonds and fixes the touch panel and the cover 142 , but also transmits light emitted by the touch panel.

In order to more clearly illustrate the function of the sliding assembly 20 according to the embodiment of the present invention, referring to FIG. 5 , in some embodiments, the electronic device 100 includes a front camera 42 , the sliding assembly 20 includes a carrier 22 , and the front camera 42 is provided with on the carrier 22 . In this way, the front camera 42 can slide with the slide assembly 20 . Of course, the user can open the front camera 42 and close the front camera 42 as the trigger signal, that is to say, when the user opens the front camera 42, the sliding component 20 is triggered to slide out, and when the user closes the front camera 42, Trigger slide assembly 20 to slide back. In this way, the user only needs to open or close the front camera according to the existing habits, and does not need to perform another operation on the sliding component 20, which can facilitate the use of the user.

In addition to the front camera 42 , the carrier 22 may also carry other functional devices 40 , such as a light sensor, a proximity sensor, an earpiece 44 , etc., as shown in FIG. 1 . These functional devices 40 can be exposed from the body 10 as the sliding assembly 20 slides out according to the user's input to work normally, or can be accommodated in the body 10 according to the user's input as the sliding assembly 20 slides back. In this way, the display assembly 14 can be provided with as few through holes as possible, which is beneficial to meet the design requirements of the full screen of the electronic device 100 .

Specifically, when the light sensor is carried on the carrier 22, the light sensor can be arranged on the top of the carrier 22, that is to say, when the sliding component 20 is completely accommodated in the chute 16, the light sensor can still be removed from the carrier 22. The top of the piece 22 is exposed, thereby sensing light in real time.

Please refer to FIG. 6 , when the carrier 22 carries the proximity sensor and the receiver 44, the user can answer and hang up the phone as a trigger signal, that is to say, when the user answers the phone, the trigger sliding component 20 slides out, When the user hangs up the phone, the sliding component 20 is triggered to slide back. In this way, the user only needs to answer or hang up the phone according to the existing habits, and does not need to perform another operation on the sliding component 20, which can be convenient for the user to use.

It can be understood that a plurality of functional devices 40 may be carried on the same carrier 22, or may be carried on multiple carriers. When a plurality of functional devices 40 are carried on the same carrier 22, the plurality of functional devices 40 can be arranged longitudinally, and the processor 36 can control whether the functional devices 40 provided at the lower part of the carrier 22 are slid out by controlling the sliding distance of the sliding assembly 20. exposed. When multiple functional devices 40 are carried on the same multiple carriers 22 , the processor 36 can select the functional device 40 to be exposed by controlling the sliding of a certain carrier 22 .

Referring to FIG. 7 , in some embodiments, the sliding assembly 20 includes a threaded hole 24 disposed in the middle of the carrier 22 and a rotating screw 26 matched with the threaded hole 24 . The chute 16 includes a groove 162 disposed opposite the threaded hole 24 and located at the bottom of the chute 16 . The electronic device 100 includes the drive assembly 50 disposed in the groove 162 . The drive assembly 50 includes a drive motor 52 connected to the processor 36 and an output shaft (not shown) connected to the bottom of the rotating lead screw 26 .

It is understood that the processor 36 can control the sliding of the sliding assembly 20 by controlling the driving motor 52 . When the user commands the sliding assembly 20 to slide from the first position A to the second position B, the processor 36 controls the driving motor 52 to rotate forward, so that the output shaft drives the rotating screw 26 to rotate in the threaded hole 24 , thereby making the sliding assembly 20 rotate. Slide from the first position A to the second position B. When the user commands the sliding assembly 20 to slide from the second position B to the first position A, the processor 36 controls the driving motor 52 to reverse, so that the output shaft drives the rotating screw 26 to rotate in the threaded hole 24, thereby causing the sliding assembly 20 to rotate. Slide from the second position B to the first position A. It is worth noting that "from the first position A to the second position B" and "from the second position B to the first position A" here refer to the direction of sliding, rather than the starting point and end point of the sliding.

The electronic device 100 of the embodiment of the present invention uses the Hall element 34 and the magnetic field generating element 32 to determine the current relative position of the sliding assembly 20 , and can detect the sliding assembly 20 in real time when the functional device 40 such as the front camera is carried on the sliding assembly 20 . state to determine the position of the functional device 40 .

It can be understood that the functional devices 40 such as the front camera 42 need to be exposed from the main body 10 , otherwise they cannot work normally. The electronic device 100 according to the embodiment of the present invention carries the functional device 40 on the sliding assembly, so that the functional device 40 is accommodated in the main body 10 when it does not need to work, and is exposed from the main body 10 along with the sliding assembly 20 when it needs to work. In this way, there is no need to open a through hole on the display assembly 14 for exposing the functional device 40 such as the front camera 42, thereby increasing the screen ratio and improving the user experience.

In the related art, the current position of the current sliding assembly 20 is known by the magnetic field signal strength between the magnetic field generating element 32 and the Hall element 34. For example, the magnetic field signal strength and the current sliding-out position of the sliding assembly 20 are calibrated in advance according to a large amount of experimental data. Therefore, the corresponding sliding-out position is matched according to the currently detected magnetic field signal strength.

However, it is not difficult to understand that when the external electromagnetic field interferes, the accuracy of the detected electromagnetic signal between the magnetic field generating element 32 and the Hall element 34 will be affected, resulting in inaccurate speed control of the sliding assembly 20. , when the control node of the speed change control of the sliding assembly 20 is at the front, the sliding assembly 20 may be unable to start, and when the control node of the speed change control of the sliding assembly 20 is at the back, the total sliding time of the slider will be increased.

In order to solve the technical problem of inaccurate shifting control due to external electromagnetic interference, the present invention also proposes a shifting method for preventing electromagnetic interference. FIG. 8 shows a shifting method for preventing electromagnetic interference of a sliding assembly according to an embodiment of the present invention. The flowchart, as shown in Figure 8, the method includes:

Step 101, controlling the driving component to start the sliding component according to the preset first speed, and start the timer.

Step 102 , according to the working parameters of the drive assembly, calculate the gliding time of the sliding assembly corresponding to the preset speed-variable gliding distance.

The working parameters include hardware working parameters of the driving component. For example, when the driving component includes a stepping motor, the working parameters include the pulse width modulation period and the number of pulse width modulation cycles required per unit number of steps.

Step 103 , when the sliding time is reached according to the timer, control the driving component to switch from the first speed to the second speed to drive the sliding component to run to the target position, wherein the second speed is greater than the first speed.

It should be understood that, according to the operation mechanism of the sliding component, the driving component controls the sliding component to start from the starting speed, and then switches to the limit speed after a certain position, thereby not only ensuring the smooth start of the driving component, but also shortening the sliding component. Time to reach the target location.

Wherein, in the embodiment of the present invention, the starting speed is represented by the first speed, and the limit speed is represented by the second speed. Obviously, the second speed is greater than the first speed.

In the embodiment of the present invention, considering that the operation of the hardware is generally not disturbed by external magnetic fields, etc., the accuracy of sliding distance measurement in a short distance range based on hardware operating parameters is greater than that obtained based on software operating parameters such as electromagnetic signals. The distance is determined based on the hardware parameters of the drive assembly to determine the moving position of the sliding assembly to realize the grasp and control of its speed change node.

Specifically, the driving component is controlled to start the sliding component according to the preset first speed, and the timer is started, and according to the working parameters of the driving component, the sliding time corresponding to the preset variable speed sliding distance of the sliding component is calculated, wherein the preset sliding distance The variable-speed sliding distance is the distance when the target position of the above-mentioned equilibrium starting speed and sliding time is reached according to the operation mechanism of the sliding component.

Further, when it is known that the sliding time arrives according to the timer, the driving assembly is controlled to switch from the first speed to the second speed to drive the sliding assembly to run to the target position.

That is to say, in the embodiment of the present invention, considering the stability of the operation mechanism of the driving component, the time it takes to drive to the target position at a certain speed is actually relatively fixed. Therefore, whether it moves to the target position is determined based on this time The corresponding target position has high accuracy.

In order to further improve the accuracy of the control of the variable speed nodes of the sliding components, in the actual execution, the corresponding variable speed sliding distance is dynamically set in real time. The details are as follows:

In an embodiment of the present invention, as shown in FIG. 9 , the above step 101 includes:

Step 201: Obtain a first startup instruction.

Wherein, the first start instruction can be set in different forms according to different application scenarios. For example, when the driving component has the function of speech recognition, the first start command is in the form of speech, and for example, when the driving component has the function of semantic recognition, The first activation instruction is in the form of text or the like.

In some embodiments, the first activation instruction may be input by a user. In this way, the sliding of the sliding assembly is achieved. As previously mentioned, the sliding of the sliding assembly can be controlled by controlling a stepper motor according to user input. When receiving the first control command input by the user, the drive assembly controls the stepper motor to rotate forward or reverse, so that the output shaft drives the rotating screw to rotate in the threaded hole, thereby making the sliding assembly slide to a predetermined position.

Of course, the trigger signal can also be set so that the driving assembly controls the sliding assembly to move under certain conditions. For example, when a proximity sensor and an earpiece are carried on the bearer, the user answering the phone and hanging up the phone can be used as trigger signals. For example, when the user answers the call, the triggering drive component controls the sliding component to slide out automatically, and when the user hangs up the call, the sliding component is triggered to slide back automatically. All in all, the sliding of the sliding component can be based on user actions, or it can happen automatically under certain circumstances. Of course, the user can set specific circumstances under which automatic sliding is performed or automatic sliding is turned off.

Step 202 , controlling the drive assembly to activate the sliding assembly from a first position at a preset first speed according to the first activation instruction.

Specifically, as analyzed above, according to the working principle of the drive assembly, the drive assembly is controlled to start the sliding assembly from the first position at a preset first speed according to the first start instruction, and at this time, the first position can be understood as the contraction of the sliding assembly The initial position when entering the electronic device body.

Further, with continued reference to FIG. 9 , the above step 103 includes:

Step 203 , setting the speed change gliding distance according to the first position, and calculating the glide time corresponding to the preset speed change gliding distance of the sliding component according to the operating parameters of the drive assembly.

With the use of the sliding assembly, under the influence of dust and the like, even if the sliding assembly retracts into the initial position of the electronic device body, the initial position may not be exactly the same. Therefore, the variable speed sliding distance is set in real time according to the current first position.

Specifically, the shifting sliding distance is set according to the first position, so that even if the current first position is different from the previous first position, since the current shifting sliding distance is set according to the current first position, the determined shifting sliding distance is the same as the current first position. The current position of the sliding assembly is consistent with the actual situation. According to the working parameters of the driving assembly, the calculated sliding time of the sliding assembly and the preset sliding distance of the speed change is relatively accurate, thereby ensuring the accuracy of the control of the speed change node of the sliding assembly. .

In an embodiment of the present invention, as shown in FIG. 10 , the above step 101 includes:

Step 301: Obtain a second startup instruction.

Similarly, the second startup instruction can be set in different forms according to different application scenarios. For example, when the driving component has the function of speech recognition, the second startup instruction is in the form of speech, and for example, when the driving component has the function of semantic recognition , the second start instruction is in text form, etc.

In some embodiments, the second activation instruction may be input by the user. In this way, the sliding of the sliding assembly is achieved. As previously mentioned, the sliding of the sliding assembly can be controlled by controlling a stepper motor according to user input. When receiving the second control command input by the user, the drive assembly controls the stepper motor to rotate forward or reverse, so that the output shaft drives the rotating screw to rotate in the threaded hole, thereby making the sliding assembly slide to a predetermined position.

Of course, the trigger signal can also be set so that the driving assembly controls the sliding assembly to move under certain conditions. For example, when a proximity sensor and an earpiece are carried on the bearer, the user answering the phone and hanging up the phone can be used as trigger signals. For example, when the user answers the call, the triggering drive component controls the sliding component to slide out automatically, and when the user hangs up the call, the sliding component is triggered to slide back automatically. All in all, the sliding of the sliding component can be based on user actions, or it can happen automatically under certain circumstances. Of course, the user can set specific circumstances under which automatic sliding is performed or automatic sliding is turned off.

Step 302 , controlling the drive assembly to activate the sliding assembly from a third position at a preset first speed according to the second activation instruction, wherein the third position is located between the first position and the second position.

Wherein, the first position is the initial position when the sliding assembly is retracted into the electronic device body, and the second position is the position where the sliding assembly is shifting gears.

Further, continuing to refer to FIG. 10 , the above step 103 includes:

Step 303: Set the speed change gliding distance according to the distance difference between the third position and the first position, and calculate the glide time corresponding to the preset speed change gliding distance of the sliding component according to the operating parameters of the drive assembly.

It should be understood that, due to insufficient power or other reasons, the fault stops at the third position between the first position and the second position. At this time, after the fault is eliminated, for example, after the electronic device is connected to the charging power source, the Two start instructions, thus, according to the second start instruction, the drive assembly is again controlled to start the sliding assembly from the third position according to the preset first speed. The distance difference between the position and the first position is used to set the speed change gliding distance, and the speed change gliding distance is set according to the remaining required gliding distance, and then, according to the working parameters of the drive assembly, the glide time corresponding to the preset speed change gliding distance of the sliding component is calculated.

Among them, the way of calculating the taxiing time is different in different application scenarios. In some possible embodiments, when the driving motor 52 in FIG. 7 is a stepping motor, the pulse width modulation period of the stepping motor and the unit step are obtained. Calculate the required number of pulse width modulation cycles, and calculate the sliding time corresponding to the sliding component and the preset variable speed sliding distance according to the pulse width modulation period and the number of pulse width modulation cycles.

In this embodiment, under different application scenarios, according to the pulse width modulation period and the pulse width modulation cycle number, the ways of calculating the taxiing time corresponding to the sliding component and the preset variable speed taxiing distance are different:

As a possible implementation, the product of the pulse width modulation period and the number of pulse width modulation cycles is used as the glide time. In this embodiment, it can be understood that the pulse width modulation period is the time occupied by each pulse width. The glide time can be obtained by multiplying the width modulation period and the total number of pulse width modulation cycles.

As another possible implementation, obtain the speed ratio of the stepping motor, the total number of steps in one revolution of the stepping motor, and the distance in which the large gear rotates one revolution, and apply a preset algorithm to the variable speed glide distance, pulse width modulation period, Calculate the speed ratio of the pulse width modulation cycle number, the total number of steps, and the distance of one revolution of the large gear to obtain the taxiing time. Among them, according to different application scenarios, the content included in the above preset algorithm is different. For example, the preset algorithm is the formula:

t=Tpwm*L*A*B*C/D
