[0001] This application relates to the field of flexible screens, and more particularly to an electronic device and a method for removing foreign objects. Background Technology

[0002] Flexible screens, characterized by their bendability, are widely used in the displays of various electronic devices to achieve adjustable screen sizes. To meet the requirement of scalable display sizes, flexible screens on electronic devices can be configured as rollable screens, meaning the screen can increase or decrease in size along a roll.

[0003] However, there may be foreign objects between the flexible screen and the roll, which may damage the flexible screen. Summary of the Invention

[0005] An electronic device, comprising:

[0006] A flexible screen includes a visible portion located on a first body of an electronic device and an invisible portion located on a second body of the electronic device. When the size of the visible portion increases, the size of the invisible portion decreases, and when the size of the visible portion decreases, the size of the invisible portion increases.

[0007] A hinge is formed around which the flexible screen extends, creating a visible portion and an invisible portion. The invisible portion is located on one side of the hinge, and the visible portion is located on the other side of the hinge.

[0008] A fan structure, located on one side of the rotating shaft, is capable of generating airflow;

[0009] An air guide structure is used to direct the airflow formed by the fan structure to a gap, which is the gap formed between the flexible screen and the rotating shaft.

[0016] The change in the state of the flexible screen includes at least one of the following: the visible part of the flexible screen switches from a display state to a non-display state; the visible part of the flexible screen switches from a non-display state to a display state; or the size of the visible part of the flexible screen increases or decreases.

[0017] Furthermore,

[0018] The controller adjusts the rotation direction of the cooling fan based on the foreign object removal command, so as to form an airflow toward the second air outlet through the air guide structure;

[0019] or,

[0020] The controller controls the first air outlet to close and the second air outlet to open based on the foreign object removal command.

[0021] Furthermore,

[0022] The rotating shaft has a hollow structure, and multiple openings are provided on the wall of the rotating shaft;

[0023] The fan structure is located at the first end of the rotating shaft. The airflow generated by the fan structure enters the interior of the rotating shaft through the opening at the first end of the rotating shaft, and is blown from the interior of the rotating shaft to the gap between the flexible screen and the non-first end of the rotating shaft through the opening at the non-first end of the rotating shaft.

[0024] Furthermore, a slider is provided inside the rotating shaft.

[0025] The slider can slide inside the rotating shaft to remove foreign objects from inside the rotating shaft.

[0026] Furthermore,

[0027] The slider is formed based on the fan structure and the airflow that enters the interior of the rotating shaft slides inside the rotating shaft.

[0028] A method for removing foreign objects includes:

[0029] If it is determined that the electronic device currently meets the foreign object removal conditions, a foreign object removal command is generated.

[0030] Based on the foreign object removal command, the air guide structure of the electronic device is controlled to blow the airflow generated by the fan structure toward the gap between the flexible screen and the hinge of the electronic device.

[0031] The flexible screen includes a visible portion on a first body of the electronic device and an invisible portion on a second body of the electronic device. When the size of the visible portion increases, the size of the invisible portion decreases, and when the size of the visible portion decreases, the size of the invisible portion increases. The flexible screen bypasses the pivot to form a visible portion and an invisible portion. The invisible portion is located on one side of the pivot, and the visible portion is located on the other side of the pivot. A gap is formed between the flexible screen and the pivot.

[0032] Furthermore, the step of controlling the airflow structure of the electronic device based on the foreign object removal command to blow the airflow formed by the fan structure toward the gap between the flexible screen and the hinge of the electronic device includes:

[0034] Furthermore, the step of controlling the airflow structure of the electronic device based on the foreign object removal command to blow the airflow formed by the fan structure toward the gap between the flexible screen and the hinge of the electronic device includes:

[0035] Based on the foreign object removal command, the second air outlet in the fan structure, which is in the same direction as the gap between the flexible screen and the pivot, is opened, so that the air guide structure blows the airflow generated by the fan structure through the second air outlet to the gap between the flexible screen and the pivot of the electronic device.

[0036] Furthermore, determining that the electronic device currently meets the foreign object removal conditions includes:

[0037] It is determined that the state of the flexible screen of the electronic device has changed;

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] This application discloses an electronic device, the schematic diagram of which is shown below. Figure 1 As shown, it includes:

[0050] Flexible screen 11, hinge 12, fan structure 13 and air guide structure 14.

[0051] The flexible screen 11 includes a visible portion located on a first body of the electronic device and an invisible portion located on a second body of the electronic device. When the size of the visible portion increases, the size of the invisible portion decreases, and when the size of the visible portion decreases, the size of the invisible portion increases.

[0052] The flexible screen 11 passes around the pivot 12, forming a visible part and an invisible part. The invisible part is located on one side of the pivot 12, and the visible part is located on the other side of the pivot 12.

[0053] The fan structure 13 is located on one side of the rotating shaft 12 and is capable of generating airflow;

[0054] The air guide structure 14 is used to guide the airflow formed by the fan structure 13 to the gap, which is the gap formed between the flexible screen 11 and the rotating shaft 12.

[0055] The electronic device includes a first body and a second body. The display screen of the electronic device is a flexible screen. A portion of the flexible screen is located on the first body of the electronic device, and another portion is located on the second body of the electronic device. The portion of the flexible screen located on the first body of the electronic device is the visible portion, and the portion of the flexible screen located on the second body of the electronic device is the invisible portion. The visible portion of the flexible screen can display the output image of the electronic device, while the invisible portion of the flexible screen does not display an image.

[0056] The dimensions of the visible and invisible portions of a flexible screen can change. When the visible portion of the flexible screen decreases, the reduced portion is adjusted to become invisible, and the size of the invisible portion increases. This increased portion is the same as the reduced portion of the visible portion. In other words, the visible portion of the flexible screen used to display the output image in the electronic device decreases. Conversely, when the visible portion of the flexible screen increases, the size of the invisible portion decreases, and the reduced portion of the invisible portion is adjusted to become the increased portion of the visible portion. In other words, the visible portion of the flexible screen used to display the output image in the electronic device increases.

[0057] The flexible screen is designed to rotate around a pivot, creating a visible and an invisible portion. The invisible portion is located on one side of the pivot, and the visible portion is on the other side. When the size of the visible portion of the flexible screen increases or decreases, the screen moves along the pivot, thus increasing or decreasing the size of the visible portion.

[0058] When the flexible screen moves around the pivot, a narrow gap is formed between the flexible screen and the pivot. If there are foreign objects in this gap, such as dust, hair, or pieces of paper, the foreign objects in the gap may damage the flexible screen as the flexible screen moves along the pivot, such as scratching the flexible screen.

[0059] To prevent the flexible screen from being damaged by foreign objects in the gaps, this solution uses an air guide structure to direct the airflow generated by the fan structure to the gaps, thereby blowing away the foreign objects and preventing them from damaging the flexible screen, thus improving the service life of the flexible screen.

[0060] The hinge can be located at the second body of the electronic device, or at the connection between the first body and the second body.

[0061] The portion of the flexible screen on one side of the pivot is invisible, and the portion of the flexible screen on the other side of the pivot is visible. If the invisible portion is located on the first side of the pivot and the visible portion is located on the second side of the pivot, then the first side of the pivot is the second body, and the second side of the pivot is the first body.

[0062] The fan structure and the air guide structure are located on the same side of the rotating shaft. For example, if both the fan structure and the air guide structure are located on the first side of the rotating shaft, that is, on the second body of the electronic device, the air guide structure and the fan structure will not affect the output content displayed on the visible part. The air guide structure directs the airflow generated by the fan structure to the gap between the rotating shaft and the flexible screen, so that the airflow can blow away foreign objects in the gap and prevent foreign objects in the gap from damaging the flexible screen when the flexible screen moves along the rotating shaft.

[0063] The electronic device disclosed in this embodiment includes: a flexible screen, a hinge, a fan structure, and an air guide structure. The flexible screen includes a visible portion located on a first body of the electronic device and an invisible portion located on a second body of the electronic device. When the size of the visible portion increases, the size of the invisible portion decreases; conversely, when the size of the visible portion decreases, the size of the invisible portion increases. The flexible screen bypasses the hinge, forming both the visible and invisible portions. The invisible portion is located on one side of the hinge, and the visible portion is located on the other side. The fan structure is disposed on one side of the hinge and is capable of generating airflow. The air guide structure directs the airflow generated by the fan structure to a gap formed between the flexible screen and the hinge. This solution uses the air guide structure to direct the airflow generated by the fan structure to the gap between the flexible screen and the hinge, so that foreign objects in the gap can be blown away by the airflow, avoiding damage to the flexible screen and improving its service life.

[0064] This embodiment discloses an electronic device, the structural schematic diagram of which is shown below. Figure 1 As shown, it includes:

[0065] Flexible screen 11, hinge 12, fan structure 13 and air guide structure 14.

[0066] In addition to the same structure as the previous embodiment, the fan structure in this embodiment includes: a cooling fan, a first air outlet, and a second air outlet.

[0067] The cooling fan is used to generate airflow;

[0068] The first air outlet faces the outside of the electronic device, and the air guide structure can guide the airflow generated by the cooling fan through the first air outlet to the outside of the electronic device.

[0069] The second air outlet faces the direction of the hinge, and the air guide structure can guide the airflow generated by the cooling fan through the second air outlet to the gap between the flexible screen and the hinge.

[0070] During operation, electronic devices perform data processing, which can cause the internal components of the device to heat up. Therefore, electronic devices are usually equipped with heat dissipation structures to dissipate heat.

[0071] The heat dissipation structure mainly includes a cooling fan to generate airflow. To achieve the function of dissipating heat from the electronic device, the structure also includes a first air outlet, which faces outwards. When airflow is discharged through the first air outlet, the temperature of the internal components of the electronic device is reduced. A schematic diagram of the airflow discharged through the first air outlet in the heat dissipation structure can be seen as follows: Figure 2 As shown, it includes: a cooling fan 21 and a first air outlet 22. Figure 2 The direction indicated by the middle arrow is the direction in which the airflow is directed through the first air outlet.

[0072] In this solution, in order to achieve the function of cleaning foreign objects between the flexible screen and the hinge through the fan structure, a second air outlet needs to be added to the fan structure.

[0073] The second air outlet faces the direction of the hinge. When the airflow from the heat dissipation structure is discharged through this outlet, it can blow away foreign objects in the gap between the flexible screen and the hinge, effectively preventing damage to the flexible screen and extending its lifespan. A schematic diagram of the airflow from the heat dissipation structure through the second air outlet is shown below. Figure 3 As shown, it includes: a cooling fan 31, a second air outlet 32, and a hinge 33. Figure 3 The direction indicated by the middle arrow is the direction in which the airflow is directed through the second air outlet.

[0074] It should be noted that the fan structure can be as follows: Figure 2 and Figure 3 The fan structure can be located at one end of the hinge in the electronic device; alternatively, it can be located at more than one end of the hinge, but rather starting from one end of the hinge in the electronic device, a fan structure can be installed at regular intervals until the other end of the hinge is reached; or, it can be located in the middle of one side of the hinge in the electronic device; or, it can be located at the other end of one side of the hinge in the electronic device.

[0075] Electronic devices incorporate airflow guidance structures that control the direction of airflow from the fan mechanism; in other words, the airflow guidance structure controls the direction in which the airflow generated by the cooling fan exits. When the electronic device needs cooling, the airflow guidance structure directs the airflow from the fan along... Figure 2 The airflow is directed through the first vent, as indicated by the middle arrow, to dissipate heat from the electronic device to the outside via airflow. When the electronic device needs to be cleared of foreign objects from crevices, the airflow guide structure controls the fan's airflow along... Figure 3The direction indicated by the middle arrow is directed through the second air outlet so that the airflow is blown towards the gap between the flexible screen and the rotating shaft, blowing foreign objects in the gap to the outside of the gap, so as to avoid damage to the flexible screen by foreign objects in the gap.

[0076] The electronic device disclosed in this embodiment includes: a flexible screen, a hinge, a fan structure, and an air guiding structure. The fan structure includes: a cooling fan, a first air outlet, and a second air outlet. The cooling fan generates airflow. The first air outlet faces outward of the electronic device, and the air guiding structure directs the airflow generated by the cooling fan through the first air outlet to the outside of the electronic device. The second air outlet faces the direction of the hinge, and the air guiding structure directs the airflow generated by the cooling fan through the second air outlet to the gap between the flexible screen and the hinge. This solution provides two air outlets in different directions for the fan structure, enabling the cooling fan to perform different functions through these outlets. Specifically, the first air outlet dissipates heat from the electronic device, while the second air outlet clears foreign objects from the gap between the flexible screen and the hinge. This solution requires only simple modifications to the existing structure to achieve the cooling fan's different functions, ensuring both heat dissipation for the electronic device and the lifespan of the flexible screen.

[0077] Furthermore, the electronic device disclosed in this embodiment may also include:

[0078] The controller generates a foreign object removal command when it determines that the state of the flexible screen has changed, and controls the air guide structure to blow air through the second air outlet to the gap between the flexible screen and the rotating shaft based on the foreign object removal command.

[0079] The changes in the state of the flexible screen include at least one of the following: the visible part of the flexible screen switches from a display state to a non-display state, the visible part of the flexible screen switches from a non-display state to a display state, or the size of the visible part of the flexible screen increases or decreases.

[0080] Specifically, electronic devices can monitor the status of the flexible screen, such as determining whether the visible part of the flexible screen has switched from a display state to a non-display state. If the visible part of the flexible screen switches from a display state to a non-display state, it indicates that the electronic device has switched from a powered-on state to a powered-off state or a standby state. At this time, it is necessary to clean the gap between the flexible screen and the hinge to ensure that there are no foreign objects in the gap and to avoid damage to the flexible screen. If it is determined that the visible part of the flexible screen is always in a display state, that is, it has not switched states, then it is not necessary to clean the gap between the flexible screen and the hinge to save energy.

[0081] Determine whether the visible portion of the flexible screen has switched from a non-display state to a display state. If it has, it indicates that the electronic device has switched from a power-off or standby state to a powered-on state. In this case, the gap between the flexible screen and the hinge needs to be cleaned to ensure that there are no foreign objects in the gap, thus avoiding damage to the flexible screen. If the visible portion of the flexible screen is always in a non-display state, i.e., no state switch has occurred, then there is no need to clean the gap between the flexible screen and the hinge to save energy.

[0082] Determine whether the visible portion of the flexible screen has increased or decreased in size. If it has, the flexible screen will move relative to the pivot. In this case, it is necessary to clean the gap between the flexible screen and the pivot to prevent foreign objects in the gap from damaging the flexible screen during its movement. If it has not changed in size, the gap does not need to be cleaned to save energy.

[0083] When a change in the state of the flexible screen is detected, the controller can generate a foreign object removal command based on the change in the state of the flexible screen, and control the fan structure and / or air guide structure based on the foreign object removal command, so that the air guide structure can blow the airflow generated by the fan structure through the second air outlet to the gap between the flexible screen and the rotating shaft, thereby achieving the purpose of cleaning foreign objects in the gap and ensuring that the flexible screen is not damaged.

[0084] The controller in the electronic device can control the state of the fan structure and / or air guide structure based on the foreign object removal command. Specifically, the controller can control whether the fan structure is in a running state or a stopped state. If the fan structure is in a running state, the controller can also control the opening of the first air outlet or the second air outlet in the fan structure to blow the airflow generated by the fan structure to the outside of the electronic device or to the gap between the flexible screen and the hinge. If the fan structure is controlled based on the foreign object removal command, the second air outlet in the fan structure can be opened based on the foreign object removal command. Alternatively, the controller can control the closing of the first air outlet or the second air outlet in the fan structure. If the controller controls the fan structure based on the foreign object removal command, the first air outlet in the fan structure can be closed based on the foreign object removal command. In this case, the second air outlet must be in the open state.

[0085] In addition, the controller can also control the rotation direction of the cooling fan in the fan structure based on the foreign object removal command. By adjusting the rotation direction of the fan structure, the airflow generated by the fan structure can be directed to the second air outlet through the air guide structure. For example, when the rotation direction of the fan structure is the first direction, the airflow generated by the cooling fan can be directed to the first air outlet through the air guide structure; when the rotation direction of the fan structure is the second direction, the airflow generated by the cooling fan can be directed to the second air outlet through the air guide structure.

[0086] In addition, the controller can also control the rotation speed of the cooling fan in the fan structure based on foreign object removal commands. Different rotation speeds create airflow of varying intensities, allowing for the removal of foreign objects of different sizes from the gap between the flexible screen and the hinge. The rotation speed of the cooling fan can be specifically determined based on the size of the foreign object in the gap to achieve complete removal and thus protect the flexible screen.

[0087] Furthermore, when the controller controls the fan structure based on the foreign object removal command, it can further control the speed of the cooling fan in the fan structure based on whether the electronic equipment has heat dissipation requirements.

[0088] When the state of the flexible screen changes, a foreign object removal command is generated. Based on the foreign object removal command, the air guide structure is controlled to blow airflow through the second air outlet to the gap between the flexible screen and the rotating shaft. The speed of the cooling fan in the fan structure can be adjusted.

[0089] At this point, if it is determined that the electronic device has no heat dissipation requirement, the speed of the cooling fan can be controlled to the first speed. If the electronic device has a heat dissipation requirement, the speed of the cooling fan can be controlled to the second speed. The second speed is greater than the first speed, so as to ensure that the airflow generated by the cooling fan can not only meet the heat dissipation requirement, but also supply the airflow required to remove foreign objects from the gap between the flexible screen and the hinge.

[0090] The controller controls the state of the air guiding structure, specifically: the controller can control the air guiding structure to be in different states to control the air guiding direction of the air guiding structure. When the controller controls the air guiding structure to be in the first state, the air guiding direction of the air guiding structure is the first air outlet of the fan structure. That is, at this time, the air guiding structure can guide the airflow generated by the cooling fan in the fan structure to the first air outlet. When the controller controls the air guiding structure to be in the second state, the air guiding direction of the air guiding structure is the second air outlet of the fan structure. That is, at this time, the air guiding structure can guide the airflow generated by the cooling fan in the fan structure to the second air outlet.

[0091] This embodiment discloses an electronic device, the structural schematic diagram of which is shown below. Figure 1 As shown, it includes:

[0092] Flexible screen 11, hinge 12, fan structure 13 and air guide structure 14.

[0093] In addition to the same structure as the previous embodiment, the rotating shaft in this embodiment is a hollow structure with multiple openings on its wall.

[0094] The fan structure is located at the first end of the rotating shaft. The airflow generated by the fan structure enters the interior of the rotating shaft through the opening at the first end of the rotating shaft, and is blown from the interior of the rotating shaft to the gap between the flexible screen and the non-first end of the rotating shaft through the opening at the non-first end of the rotating shaft.

[0095] The flexible screen wraps around the pivot, forming both visible and invisible portions, such as... Figure 4 As shown, it includes: the visible portion 41 of the flexible screen, the invisible portion 42 of the flexible screen, and the hinge 43.

[0096] The fan structure is located at the first end of the first side of the shaft, such as Figure 3 As shown, in order to ensure that the airflow generated by the fan structure can completely blow through the gap between the flexible screen and the hinge, the hinge needs to be designed as a hollow structure. A cross-sectional diagram of the hollow hinge is shown below. Figure 5 As shown.

[0097] Multiple openings are provided on the wall of the hollow rotating shaft. The airflow generated by the fan structure enters the interior of the rotating shaft through the opening at the first end of the first side. Then, the airflow reaches the outside of the rotating shaft through other openings and enters the gap between the flexible screen and the rotating shaft, such as... Figure 6 As shown, it includes: a fan structure 61, a rotating shaft 62, and a plurality of openings 63 on the wall of the rotating shaft.

[0098] The fan structure 61 generates airflow, which enters the hollow structure of the rotating shaft through the opening on the wall of the rotating shaft at the position corresponding to the fan structure 61. The airflow flows inside the hollow structure of the rotating shaft. When the airflow flows inside the hollow structure of the rotating shaft, if the airflow encounters the opening 63, part of the airflow will reach the outside of the hollow structure of the rotating shaft through the opening. For the airflow that reaches the outside of the hollow structure of the rotating shaft, part of it will reach the gap between the flexible screen and the rotating shaft. This part of the airflow can remove foreign objects in the gap at the opening.

[0099] Except for the opening at the first end on the first side, airflow can flow from the inside of the hollow structure to the outside through each opening on the rotating shaft. This allows foreign objects at different locations in the gap between the flexible screen and the rotating shaft to be removed through the multiple openings on the rotating shaft.

[0100] The higher the rotation speed of the cooling fan in the fan structure, the stronger the airflow. The stronger the airflow distributed to each opening on the shaft, the better it can remove foreign objects that are difficult to remove from the gaps, thereby improving the cleaning effect of foreign objects in the gaps and preventing the flexible screen from being damaged by foreign objects in the gaps.

[0101] The electronic device disclosed in this embodiment includes: a flexible screen, a hinge, a fan structure, and an air guide structure. The hinge is a hollow structure with multiple openings on its walls. The fan structure is located at the first end of the hinge. The airflow generated by the fan structure enters the interior of the hinge through the openings at the first end and is blown from the interior of the hinge to the gap between the flexible screen and the non-first end of the hinge through openings at other locations. This solution, by providing multiple openings on the walls of the hollow hinge, allows the airflow generated by the fan structure to enter the hinge through these openings and reach the gap between the flexible screen and the hinge through openings at other locations. This avoids the situation where the fan structure is only located at the first end of the hinge and can only clean foreign objects in the gap at that first end. Instead, by using openings at different locations on the hinge, foreign objects in different gap locations can be cleaned, ensuring the cleaning effect of foreign objects in the gap and improving the service life of the flexible screen.

[0102] Furthermore, in the electronic device disclosed in this embodiment, a slider may be provided inside the hollow rotating shaft. The slider can slide inside the rotating shaft to remove foreign objects inside the rotating shaft.

[0103] Foreign objects inside the shaft can be removed by airflow or by using a slider.

[0104] If the removal is done using a slider, a slider needs to be installed inside the rotating shaft, such as... Figure 7 As shown, it includes: a rotating shaft 71 and a slider 72.

[0105] The slider slides back and forth inside the rotating shaft, thereby removing foreign objects from inside the rotating shaft to one end of the rotating shaft. This prevents foreign objects from remaining inside the rotating shaft and from entering the gap between the flexible screen and the rotating shaft when foreign objects are removed by airflow.

[0106] Accommodation spaces can be set at both ends of the rotating shaft. When the slider slides to one end inside the rotating shaft, if there are foreign objects inside the rotating shaft, the foreign objects can be pushed into the accommodation space at that end to prevent them from remaining inside the rotating shaft.

[0107] Furthermore, the slider can also slide inside the shaft based on the airflow formed by the fan structure and entering the shaft.

[0108] The slider's movement inside the hinge can be directly achieved based on airflow. That is, the slider's movement inside the hinge does not require the support of other electrical signals. As long as the airflow from the fan structure enters the hinge, the airflow inside the hinge can push the slider to the second end of the hinge. During the process of the airflow pushing the slider to the second end of the hinge, if there are foreign objects at the location where the slider slides, they will be pushed to the second end of the hinge so that they can enter the receiving space at the second end of the hinge, thus preventing them from remaining inside the hinge and thus preventing them from entering the gap between the flexible screen and the hinge and causing damage to the flexible screen.

[0109] When the fan structure no longer generates airflow, or when the airflow generated by the fan structure no longer enters the interior of the shaft, the slider can move from the second end of the shaft back to its original position, which can be: the first end of the shaft, or a position inside the shaft near the first end.

[0110] This embodiment discloses a method for removing foreign objects, the flowchart of which is shown below. Figure 8 As shown, it includes:

[0111] Step S81: If it is determined that the electronic device currently meets the foreign object removal conditions, generate a foreign object removal command;

[0112] Step S82: Based on the foreign object removal command, control the air guide structure of the electronic device to blow the airflow generated by the fan structure toward the gap between the flexible screen and the rotating shaft of the electronic device.

[0113] The flexible screen includes a visible portion on a first body of the electronic device and an invisible portion on a second body of the electronic device. When the size of the visible portion increases, the size of the invisible portion decreases, and when the size of the visible portion decreases, the size of the invisible portion increases. The flexible screen passes around a pivot to form a visible portion and an invisible portion.
