[0047] The embodiments of this utility model will now be described in detail. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0048] To save space, existing electronic devices are typically designed with a foldable structure, generally consisting of a first part 11 and a second part 12 that can rotate relative to each other. Examples include foldable screen phones, laptops 1, and foldable displays. During use, foreign objects 2 can easily fall between the rotating first part 11 and the second part 12. If these foreign objects 2 are not removed promptly when folding the first part 11 and the second part 12, damage to at least one of them can easily occur.

[0049] Taking laptop 1 as an example. (For reference...) Figure 9 As shown, laptop computer 1 has a screen section and a main unit section that can rotate relative to each other. Typically, the screen section is the part with the display screen, and the main unit section is the part with the keyboard, CPU, processor, and other major computer components. Due to bad habits, some users habitually place miscellaneous items, such as pens, headphones, and external hard drives, on the main unit section of laptop computer 1. If these miscellaneous items are not removed promptly when closing laptop computer 1, the screen section of laptop computer 1 is prone to damage such as... Figure 8 The screen breakage issue shown here not only causes financial loss to users, but also creates significant inconvenience for their normal work and daily life.

[0050] Therefore, this application provides an electronic device to at least solve the above-mentioned problems. The electronic device described in this application can be an electronic product having a first part 11 and a second part 12 that have a rotating connection, such as a foldable screen phone, a foldable display screen, or a laptop computer 1. Taking a laptop computer 1 as an example, see below. Figure 1 , Figure 2 As shown, the first part 11 can be the screen portion, and the second part 12 can be the main body portion. Taking a foldable screen phone as an example, the first part 11 can be the first foldable screen, and the second part 12 can be the second foldable screen. This application does not limit the specific product type of the electronic device.

[0051] For reference Figure 1As shown, the electronic device described in this application further includes a position sensor 13, a pressure detection unit 14, and an alert unit 15. The position sensor 13 is disposed at at least one of the first part 11 and the second part 12. In other words, the position sensor 13 can be disposed only on the first part 11, only on the second part 12, or simultaneously on both parts 11 and 12. The position sensor 13 can detect the relative position information between the first part 11 and the second part 12, and send a first activation signal when the first part 11 and the second part 12 are in a preset position. The preset position can be the position where the first part 11 and the second part 12 are rotated closer to each other to a certain extent, for example, the preset position can be the position where the first part 11 and the second part 12 are at an angle of 60 degrees, 45 degrees, 30 degrees, etc. The first activation signal indicates that the user may have performed an operation of folding and closing the first part 11 and the second part 12, which is used to activate the pressure detection unit 14 to detect pressure.

[0052] For reference Figure 2 and Figure 3 As shown, the number and location of position sensors 13 depend on the actual needs and the type of sensor used. For example, position sensors 13 can be a Hall switch 131 located on one of the first part 11 and the second part 12, and a permanent magnet 132 located on the other of the first part 11 and the second part 12, to detect the angular position information between the first part 11 and the second part 12. The number can be one, two, three, or even more. Position sensors 13 can also be proximity switches, photoelectric sensors, or other sensors that can detect the displacement of the first part 11 and the second part 12. These sensors are located at either the first part 11 or the second part 12 to detect the distance position information between a certain part of the first part 11 and a certain part of the second part 12.

[0053] For reference Figure 2 and Figure 4As shown, the pressure detection unit 14 is disposed at at least one of the first part 11 and the second part 12, and is electrically connected to the position sensor 13. In other words, the pressure detection unit 14 can be disposed only on the first part 11, only on the second part 12, or simultaneously on both the first part 11 and the second part 12. The pressure detection unit 14 can receive a first activation signal from the displacement sensor, and after receiving the first activation signal, detect the pressure information of at least one of the first part 11 and the second part 12. If the pressure information exceeds a preset range, it indicates that there is a foreign object 2 between the first part 11 and the second part 12. At this time, the pressure detection unit 14 sends a second activation signal. The second activation signal means that there is a foreign object 2 between the first part 11 and the second part 12, which prevents the rotational closing movement between the first part 11 and the second part 12, and causes the pressure on the first part 11 and the second part 12 to rise abnormally.

[0054] For reference Figure 1 and Figure 9 As shown, the reminder unit 15 is electrically connected to the pressure detection unit 14 to receive the second activation signal from the pressure detection unit 14. Upon receiving the second activation signal, the reminder unit 15 issues a reminder message 17 to remind the user to remove the foreign object 2 in a timely manner, preventing damage to the first part 11 and the second part 12 of the electronic device during the flipping and closing process due to the presence of the foreign object 2. This ensures the service life of the electronic device and effectively reduces the risk of property loss for the user.

[0055] For reference Figure 2 and Figure 3As shown, in some embodiments of this application, the position sensor 13 specifically includes a Hall switch 131 and a permanent magnet 132. The Hall switch 131 is disposed at one of the first part 11 and the second part 12, and the permanent magnet 132 is disposed at the other of the first part 11 and the second part 12. The Hall switch 131 is used to detect the position information of the permanent magnet 132 and is triggered and sends the first activation signal when the permanent magnet 132 moves to a preset position. The preset position can be the position when the first part 11 and the second part 12 rotate closer to each other to a certain extent. For example, taking a laptop 1 as an example, the Hall switch 131 can be disposed at the screen part of the laptop 1, and the permanent magnet 132 can be disposed at the main body part of the laptop 1. Alternatively, the Hall switch 131 can be disposed at the main body part of the laptop 1, and the permanent magnet 132 can be disposed at the screen part of the laptop 1. The Hall switch 131 and the permanent magnet 132 face each other in the direction of relative rotation between the screen part and the main body part. The preset position can be the position when the screen portion of the laptop 1 is at an angle of 60 degrees, 45 degrees, 30 degrees, etc., between the main body portion and the screen portion. In this embodiment, the preset position is preferably the position when the first portion 11 and the second portion 12 are at an angle of 60 degrees.

[0056] When the permanent magnet 132 moves, the magnetic field exerted by the permanent magnet 132 on the Hall switch 131 also changes accordingly. Based on the Hall effect, the semiconductor device in the Hall switch 131 generates an electron flow, thereby outputting an electrical signal. The angle between the first part 11 and the second part 12 can be determined based on the electrical signal output by the Hall switch 131. When the permanent magnet 132 is in a predetermined position, the Hall switch 131 is triggered and sends a first activation signal. Detecting the angle provides a more intuitive reflection of the user's action of flipping and closing the first part 11 and the second part 12. Compared to using a displacement sensor to reflect the user's action of flipping and closing the first part 11 and the second part 12, this method effectively simplifies the control logic for detecting the closing action using a displacement sensor, thus making it more feasible.

[0057] For reference Figure 1 and Figure 4As shown, in some embodiments of this application, the pressure detection unit 14 includes a pressure sensor 141 and a first controller 142. The pressure sensor 141 is a sensor that detects the magnitude of pressure on the current part. The first controller 142 can be a control board integrated with the pressure sensor 141, or it can be a control element independently of the pressure sensor 141 but electrically connected to it. The pressure sensor 141 is located on the side of the second part 12 facing the first part 11 to detect the pressure information between the first part 11 and the second part 12 when they rotate towards each other. When the first part 11 and the second part 12 rotate towards each other to achieve the flip-close of the electronic device, if a foreign object 2 is sandwiched between the first part 11 and the second part 12, the side of the second part 12 facing the first part 11 will be squeezed by the foreign object 2, resulting in an abnormally high pressure on a portion of that side. The pressure sensor 141 can detect the pressure information on the second part 12. The first controller 142 makes a judgment based on the pressure information detected by the pressure sensor 141. When the pressure on the second part 12 exceeds the preset range, it indicates that there is a foreign object 2 between the first part 11 and the second part 12. At this time, the first controller 142 sends a second activation signal. This setting helps the pressure sensor 141 to accurately detect the foreign object 2, with a low probability of false detection or false alarm, and can effectively ensure the accuracy of foreign object 2 detection when the electronic device flips and closes the first part 11 and the second part 12.

[0058] It should be noted that the location and number of pressure sensors 141 depend on actual needs. For example, taking a laptop 1 as an example, the pressure sensors 141 can be installed on the main unit of the laptop 1, which serves as the second part 12, specifically on the side of the main unit facing the screen, i.e., on the side of the main unit with the keyboard. Multiple pressure sensors 141 can be arranged, such as simultaneously distributed in the keyboard area and the outer bezel area of ​​the keyboard. When a foreign object 2 is sandwiched between the main unit and the screen, the pressure sensors 141 are triggered, detect abnormal pressure information, and transmit the pressure information to the first controller 142 for analysis and processing.

[0059] For reference Figure 1 and Figure 5As shown, in some embodiments of this application, the pressure detection unit 14 includes a pressure sensor 141 and a first controller 142. The pressure sensor 141 is disposed on the side of the second part 12 that contacts the external bearing surface, to detect the pressure information between the second part 12 and the external bearing surface. If a foreign object 2 is sandwiched between the first part 11 and the second part 12, the pressure information between the second part 12 and the external bearing surface will also increase. The pressure sensor 141 can detect the pressure information received on the second part 12. The first controller 142 makes a judgment based on the pressure information detected by the pressure sensor 141. When the pressure received on the second part 12 exceeds a preset range, it indicates that a foreign object 2 is sandwiched between the first part 11 and the second part 12. At this time, the first controller 142 issues a second activation signal. The above configuration increases the placement range of the pressure sensor 141, allowing the pressure sensor 141 to be placed more flexibly in electronic devices.

[0060] For reference Figure 5 As shown, taking laptop computer 1 as an example, the main body of laptop computer 1 is the second part 12 that comes into contact with an external bearing surface, such as a desktop or tabletop on which laptop computer 1 is placed. A miniature precision pressure sensor 141 is provided on the side of the main body that contacts the external bearing surface. This pressure sensor 141 can detect an abnormal increase in pressure between the main body and the external bearing surface. This abnormal increase indicates that there is a foreign object 2 on laptop computer 1.

[0061] To ensure the accuracy of the data read by the pressure sensor 141, the weight of each laptop 1 is calibrated to an accurate value at the factory. Customers can also calibrate the weight of the laptop 1 within the laptop 1 system to prevent weight changes over prolonged use. When a user closes the laptop lid, a downward force may be applied, potentially affecting the accuracy of the data read by the pressure sensor 141. To prevent false alarms, the pressure sensor 141 can be positioned in a location on the main unit where the downward pressure from closing the lid is less significant. Simultaneously, the preset range within the first controller 142 can be revised based on user habits. This means that the downward pressure applied to the main unit by the user when closing the laptop 1's screen is included in the preset range within the first controller 142. The pressure value within this preset range combines the downward pressure from the user closing the lid with the pressure exerted on the laptop 1 due to its total weight. If the pressure data read by the pressure sensor 141 exceeds this preset range, it indicates the presence of a foreign object 2 on the laptop 1.

[0062] In some embodiments of this application, the electronic device further includes a second controller. The second controller is electrically connected to the position sensor 13 and the pressure detection unit 14, respectively, and is used to set a preset position and a preset range. For example, in the laptop 1, the second controller can be a computer system component of the laptop 1. The user can operate the computer system to specifically set the preset position and preset range according to their own habits or preferences. This allows the electronic device to adjust the foreign object 2 detection settings according to user habits and preferences, thus enabling the electronic device to better suit the user's usage habits and needs, thereby improving the user experience.

[0063] For reference Figure 6 As shown, in some embodiments of this application, the electronic device further includes an electromagnet 16. The electromagnet 16 is disposed at a location in the first part 11 or the second part 12 where the permanent magnet 132 is not present, and is electrically connected to a Hall switch 131. When the Hall switch 131 in the position sensor 13 sends a first activation signal, the electromagnet 16 receives the first activation signal and is energized. At this time, the electromagnet 16 is magnetic, and along the rotation direction of the first part 11 and the second part 12, the electromagnet 16 and the permanent magnet 132 are arranged opposite each other and their polarities repel each other. When the permanent magnet 132 tends to continue approaching the electromagnet 16, the electromagnet 16 can provide a repulsive force to prevent the permanent magnet 132 from continuing to approach. This means that the first part 11 and the second part 12 are affected by the repulsive force between the permanent magnet 132 and the electromagnet 16, and are not easily allowed to continue to flip and approach each other. When the user flips and closes the first part 11 and the second part 12 roughly, the repulsive force between the permanent magnet 132 and the electromagnet 16 can provide a certain amount of damping to remind the user to pay attention to the foreign object 2 between the first part 11 and the second part 12. At the same time, it can also prevent the first part 11 and the second part 12 from being damaged due to the rough closing action.

[0064] For reference Figure 7 As shown, in some embodiments of this application, the electronic device further includes an electromagnet 16, and the electromagnets 16 are arranged in pairs. One of the electromagnets 16 in the same pair is disposed on the first portion 11, and the other of the electromagnets 16 in the same pair is disposed on the second portion 12.

[0065] Electromagnet 16 is electrically connected to Hall switch 131. When Hall switch 131 in position sensor 13 sends a first activation signal, electromagnet 16 receives the first activation signal and is energized. At this time, electromagnet 16 is magnetic, and along the rotation direction of the first part 11 and the second part 12, the positions of the same pair of electromagnets 16 are opposite each other and their polarities repel each other. When the pair of electromagnets 16 tend to move closer to each other, the pair of electromagnets 16 can provide a repulsive force to prevent the pair of electromagnets 16 from moving closer. This means that the first part 11 and the second part 12 are not easily flipped and moved closer to each other due to the repulsive force between the pair of electromagnets 16. When the user flips and closes the first part 11 and the second part 12 in a rough manner, the repulsive force between the pair of electromagnets 16 can provide a certain damping to remind the user to pay attention to the foreign object 2 between the first part 11 and the second part 12. At the same time, it can also prevent the first part 11 and the second part 12 from being damaged due to the rough closing action.

[0066] In some embodiments of this application, the electronic device is specifically a laptop computer 1. The first part 11 is the screen portion of the laptop computer 1, and the second part 12 is the main unit portion of the laptop computer 1.

[0067] Position sensor 13 is disposed on the screen portion and the main unit portion to detect the angle information between the screen portion and the main unit portion in real time. Pressure detection unit 14 is disposed on the main unit portion.

[0068] When the user adjusts the screen portion of the laptop 1, changing the angle between the screen portion and the main unit, the position sensor 13 detects the positional change and checks whether the screen portion and the main unit are moving closer together. If the screen portion and the main unit are not moving closer together, it means the user has only adjusted the screen, and the position sensor 13 does not need to perform any further action.

[0069] If the position sensor 13 detects that the screen portion and the main unit portion are moving closer together, i.e., the angle between the main unit portion and the screen portion is decreasing, the position sensor 13 begins to determine whether the angle between the main unit portion and the screen portion reaches or is less than a preset value. If the angle between the main unit portion and the screen portion does not reach or is less than the preset value, it means that the user has only adjusted the screen, and the position sensor 13 does not need to take any further action.

[0070] If the angle between the main unit and the screen reaches or is less than a preset value, the position sensor 13 sends a first activation signal to activate the pressure detection unit 14. The pressure sensor 141 of the pressure detection unit 14 collects the pressure information on the second part 12, i.e., the main unit, and sends the pressure information to the first controller 142 of the pressure detection unit 14 for judgment. If the detected pressure information does not exceed the preset range set in the first controller 142, it indicates that the angle between the main unit and the screen of the laptop 1 is normal, the user can continue to close the lid, and the pressure sensor 141 and the first controller 142 will not continue to operate.

[0071] If the detected pressure exceeds the preset range set in the first controller 142, it indicates that there is a foreign object 2 between the main body and screen of the laptop 1. (See reference...) Figure 9 As shown, at this time, the first controller 142 sends a signal to the reminder unit 15. The reminder unit 15 issues a reminder message 17 to prompt the user to remove the foreign object 2 in a timely manner. At the same time, the Hall switch 131 detects whether the user has stopped closing the lid. If the user has stopped closing the lid, the pressure sensor 141 continues to detect the pressure information until the pressure information meets the preset range. At this time, the reminder unit 15 ends the reminder. If the user continues to close the lid, the first activation signal of the Hall switch 131 can be sent to the electromagnet 16 to activate and power the electromagnet 16. At this time, the electromagnet 16 repels the permanent magnet 132 in the position sensor 13, or repels the electromagnet 16 paired with it, to prevent the user from continuing to close the lid.

[0072] For reference Figure 10 As shown, if the user removes the foreign object 2 and the pressure information detected by the pressure sensor 141 returns to the preset range, the reminder unit 15 stops reminding, and the user closes the laptop 1 normally. If the pressure information read by the pressure sensor 141 still exceeds the preset range after the user removes the foreign object 2, the reminder unit 15 continues to remind to prevent the presence of other uncleaned foreign objects 2. If the pressure information read by the pressure sensor 141 still exceeds the preset range after the user removes all foreign objects 2, the user can reset the preset range and other control parameters through the second controller, i.e., the laptop 1's own system.

[0073] In some embodiments of this application, reference may be made to Figure 9 As shown, the reminder unit 15 specifically comprises at least a portion of the display area of ​​the screen. Upon receiving the second activation signal, the reminder unit 15 displays reminder information 17.
