Description

TECHNICAL FIELD

[0002] With the development of technology, the popularity of foldable electronic devices is also increasing. Currently, the screen closure of foldable electronic devices is achieved by installing one or more pairs of magnets on the middle frame. The screen closure state of the folding screen is maintained by using the mutual attraction of the magnet pair to prevent the folding screen from accidentally unfolding.

[0003] In some related technologies, foldable electronic devices use permanent magnets to achieve screen attraction. In order to prevent the folding screen from accidentally unfolding, the attraction force is usually designed to be strong, which makes it more difficult for users to unfold the folding screen and requires overcoming the strong attraction of the permanent magnet.

[0004] In another related technology, foldable electronic devices use electromagnets to achieve screen attraction. However, electromagnets are usually small in size, and under the condition of small excitation current provided by the mobile phone battery and power supply architecture, the force between electromagnets will be greatly reduced. Without power, the magnetic attraction of the electromagnet will be weak, and the foldable electronic device does not have enough magnetic attraction to maintain the closed state, which is easily accidentally unfolded, affecting the user's experience.

[0043] In order to make the technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail in combination with the drawings.

[0044] As Figure 1As shown, the embodiment of the present application provides a foldable shell, which comprises a first shell 1, a second shell 2, a first magnetic module 3, a second magnetic module 4 and a control device.

[0045] The first shell 1 and the second shell 2 are rotationally connected, and the first magnetic module 3 is installed on the first shell 1.

[0046] The second magnetic module 4 is installed on the second shell 2, and the second magnetic module 4 comprises a magnetic piece 41 and a coil 42 wound around the outer periphery of the magnetic piece 41. The control device is electrically connected with the coil 42, and the control device is used to control the current direction of the coil 42, so as to change the magnetic polarity of the second magnetic module 4, so that the second magnetic module 4 is attracted or repelled with the first magnetic module 3. Wherein, the magnetic piece 41 is a permanent magnet with coercive force lower than 500kA / m.

[0047] Exemplarily, the first shell 1 and the second shell 2 are respectively provided with a recess, the first magnetic module 3 is installed in the recess of the first shell 1, and the second magnetic module 4 is installed in the recess of the second shell 2.

[0048] Exemplarily, as shown, Figure 4 The magnetic piece 41 is substantially columnar, and the coil 42 is wrapped around the outer periphery of the magnetic piece 41. Wherein, the vertical direction is the height direction of the magnetic piece 41.

[0049] The foldable shell has a closed state and an unfolded state. As shown, Figure 2 When the first shell 1 and the second shell 2 are stacked along the thickness direction, the foldable shell is in the closed state; when the first shell 1 and the second shell 2 are distributed side by side and substantially located in the same plane, the foldable shell is in the unfolded state.

[0050] Exemplarily, the foldable shell is applied to foldable electronic devices such as mobile phones, notebook computers, tablet computers, wearable devices and vehicle-mounted devices, and the foldable shell is a middle frame of the foldable electronic devices.

[0051] Exemplarily, the control device comprises a control piece such as a CPU (Central Processing Unit) and a SoC (System on Chip), and further comprises a power module and a switch, the control piece, the power module and the switch are electrically connected with each other, the power module is used to supply power to the coil 42, and the switch is used to change the current direction input to the coil 42. Specifically, the control piece sends an electric signal to the switch, so that the switch changes the current direction input to the coil 42 by the power module after receiving the electric signal, thereby changing the magnetic polarity of the second magnetic module 4, so that the second magnetic module 4 is attracted or repelled with the first magnetic module 3.

[0052] In this embodiment, the second magnetic module 4 is an electromagnet structure, and the first magnetic module 3 can be a permanent magnet or an electromagnet. When the first magnetic module 3 is an electromagnet, the structure of the first magnetic module 3 can be the same as that of the second magnetic module 4, or can be different from that of the second magnetic module 4.

[0053] In the related art, the existing foldable electronic device realizes the closing and attracting of the two screens by a pair of permanent magnets. The attracting force between the pair of permanent magnets is large, and in the process of closing the foldable screen, if the operation is improper, there is a risk of pinching the fingers. In addition, the foldable electronic device in the prior art will be attracted due to the attracting force between the pair of permanent magnets when the unfolding angle is small, and the unfolding angle cannot be maintained. The second magnetic module 4 in the embodiment of the present application is an electromagnet structure, which can more accurately control the attracting time of the foldable housing through the control device, reduce the risk of pinching the hand, and also can maintain the foldable housing at a smaller unfolding angle.

[0054] Specifically, the first housing 1 and the second housing 2 are rotationally connected by the shaft assembly, the first magnetic module 3 is installed at one end of the first housing 1 away from the shaft assembly, and the second magnetic module 4 is installed at one end of the second housing 2 away from the shaft assembly. The positions of the first magnetic module 3 and the second magnetic module 4 are adapted, that is, in the closed state of the foldable housing, the positions of the first magnetic module 3 and the second magnetic module 4 are opposite, so that the attracting or repelling can be better.

[0055] Coercive force, also known as coercivity or magnetizing force, is one of the characteristics of magnetic materials, and refers to the magnetic field strength required to reduce the magnetization intensity to zero after the magnetic material has been magnetized to magnetic saturation. In the embodiment of the present application, the magnetic member 41 is a low-coercivity permanent magnet with a coercive force of less than 500 kA / m. Under the condition of a small excitation current, the magnetic member 41 can change the magnetic polarity with the change of the excitation current direction, so that the second magnetic module 4 and the first magnetic module 3 attract or repel each other. Compared with the conventional electromagnet of the same volume in the prior art which only uses soft magnetic material, the second magnetic module 4 in the embodiment of the present application introduces a hard magnetic material magnetic member 41, and the magnetic energy product is larger. Under the same excitation current condition, the second magnetic module 4 can provide a larger magnetic attracting force / repelling force, which improves the defect that the conventional electromagnet has a small magnetic attracting force / repelling force.

[0056] In some optional embodiments, the coercive force of the magnetic member 41 is less than 160 kA / m.

[0057] Specifically, when the foldable housing needs to be switched from the closed state to the unfolded state, the control device controls the coil 42 to be powered on, and makes the end of the second magnetic module 4 close to the first magnetic module 3 and the end of the first magnetic module 3 close to the second magnetic module 4 have the same magnetic poles, at this time, the second magnetic module 4 and the first magnetic module 3 repel each other, so that the first housing 1 and the second housing 2 are automatically opened outward by a certain angle and move away from each other, so that the user can unfold the foldable housing more easily; in the process of switching the foldable housing from the unfolded state to the closed state, the control device controls the coil 42 to be powered on, and makes the end of the second magnetic module 4 close to the first magnetic module 3 and the end of the first magnetic module 3 close to the second magnetic module 4 have different magnetic poles, at this time, the second magnetic module 4 and the first magnetic module 3 attract each other, so that the first housing 1 and the second housing 2 move close to each other, and the foldable housing is automatically closed.

[0058] Since the magnetic member 41 is a permanent magnet, when the foldable housing is in the closed state, even if the second magnetic module 4 is not powered on, the second magnetic module 4 has magnetism and can attract the first magnetic module 3, so that the foldable housing maintains the closed posture and avoids being accidentally unfolded.

[0059] The foldable housing provided by the embodiment of the present application can control the magnetic polarity of the second magnetic module 4 by the control device, repel the second magnetic module 4 and the first magnetic module 3 when the foldable housing needs to be unfolded, so that the user can quickly unfold the first housing 1 and the second housing 2 more easily and labor-savingly, and attract the second magnetic module 4 and the first magnetic module 3 when the foldable housing needs to be closed, so that the first housing 1 and the second housing 2 can be reliably attracted; since the coercive force of the magnetic member 41 is low, a small excitation current can change the magnetic polarity, and since the magnetic member 41 is a permanent magnet, it has a large magnetic energy product, and compared with a conventional electromagnet, the magnetic member 41 can generate a larger attractive force / repulsive force under the same excitation current, so as to ensure reliable attraction or repulsion between the first magnetic module 3 and the second magnetic module 4.

[0060] In one embodiment, as shown in Figure 5 The second magnetic module 4 further includes a soft magnet 43, and the soft magnet 43 is at least partially connected with the magnetic member 41.

[0061] The soft magnet 43 is a magnetic material that is easy to be magnetized and has a low coercive force and a high magnetic permeability, and the above characteristics of the soft magnet 43 can make the second magnetic module 4 quickly respond to the excitation current and generate a magnetic field, so as to realize the attraction or repulsion between the second magnetic module 4 and the first magnetic module 3.

[0062] Further, the soft magnet 43 includes a first main body 431, as shown in Figure 5As shown, the magnetic member 41 is embedded in the first body 431, and the coil 42 is arranged around the periphery of the first body 431.

[0063] As shown, the first body 431 is provided with an inner cavity, and the magnetic member 41 is embedded in the inner cavity of the first body 431. The volume of the first body 431 is fully utilized, which is conducive to reducing the space occupied by the magnetic member 41 and improving the space utilization.

[0064] Further, as shown, Figure 6 The soft magnetic body 43 further includes a second body 432, which is annular and surrounds the periphery of the coil 42.

[0065] In this embodiment, the second body 432 has a hollow structure, and the coil 42, the first body 431 and the magnetic member 41 are located in the internal space of the second body 432, which can provide certain protection for the coil 42, the first body 431 and the magnetic member 41.

[0066] In some embodiments, the soft magnetic body 43 further includes a base portion 433, which is located at least at the bottom of the first body 431, the magnetic member 41 and the coil 42.

[0067] For example, Figure 7 As shown, the base portion 433 is located at the bottom of the first body 431, the magnetic member 41 and the coil 42, and the first body 431 is connected to the base portion 433 and protrudes relative to the base portion 433.

[0068] Alternatively, as shown, Figure 8 The base portion 433 is located at the bottom of the first body 431, the second body 432, the magnetic member 41 and the coil 42, and the first body 431 and the second body 432 are connected to the base portion 433, and the first body 431 and the second body 432 protrude relative to the base portion 433.

[0069] By providing the base portion 433, support is provided for other elements of the second magnetic module 4, facilitating the overall assembly of the second magnetic module 4 into the second shell 2 and improving the assembly efficiency of the second magnetic module 4.

[0070] In other embodiments, as shown, Figure 9 The soft magnetic body 43 includes a base portion 433 and a side wall portion 434 connected to each other, the side wall portion 434 is a hollow structure, and the base portion 433 and the side wall portion 434 surround to form a containing cavity 435, and the magnetic member 41 and the coil 42 are arranged in the containing cavity 435.

[0071] Specifically, the side wall portion 434 is annular and internally hollow, forming a cylindrical structure with one side having an opening, and the magnetic member 41 and the coil 42 are both located in the accommodating cavity 435 of the soft magnet 43, facilitating the assembly of the second magnetic module 4 into the second shell 2 and improving the assembly efficiency of the second magnetic module 4.

[0072] In one specific embodiment, the magnetic member 41 is an alnico permanent magnet or a ferrite permanent magnet.

[0073] The alnico permanent magnet or the ferrite permanent magnet is a low-coercivity permanent magnet, and the coercivity thereof is usually below 160 kA / m. By setting the magnetic member 41 as an alnico permanent magnet or a ferrite permanent magnet, the magnetic member 41 can change the magnetic polarity under a small excitation current.

[0074] In one embodiment, the first magnetic module 3 is a permanent magnet, which has high energy density and stability and can maintain magnetism for a long time. The first magnetic module 3 as a permanent magnet and the second magnetic module 4 as an electromagnet are used in combination, which can not only ensure that there is enough magnetic force between the first magnetic module 3 and the second magnetic module 4 for attraction or repulsion, but also avoid the risk of hand clamping caused by excessive attraction between the first magnetic module 3 and the second magnetic module 4.

[0075] The foldable shell further comprises a trigger 5 electrically connected to the control device, which is used to send an unfolding signal to the control device, so that the control device controls the second magnetic module 4 to repel the first magnetic module 3.

[0076] For example, the trigger 5 is a key assembly, which can be a physical key installed on the first shell 1 or the second shell 2, or a virtual key on a display screen. When the foldable shell is in a closed state, after a user presses the trigger 5, the trigger 5 sends an unfolding signal to the control device, and after receiving the unfolding signal, the control device controls the coil 42 to be energized, so that the second magnetic module 4 repels the first magnetic module 3, and the first shell 1 and the second shell 2 automatically pop out to a certain angle and move away from each other, making it easier for the user to unfold the foldable shell.

[0077] Alternatively, the trigger 5 can also be a voice recognition module, which can recognize voice commands issued by the user and send an unfolding signal to the control device.

[0078] By setting the trigger 5, when it is necessary to unfold the foldable shell, it is not necessary to manually find the middle position between the first shell 1 and the second shell 2 and then manually unfold, but only needs to operate the trigger 5, so that the control device controls the second magnetic module 4 to repel the first magnetic module 3, and the first shell 1 and the second shell 2 automatically pop out, which is simple and easy to operate and saves effort, and is conducive to improving the user's experience.

[0079] The foldable shell further comprises a detection member 6 electrically connected to the control device, the detection member 6 is configured to send a closing signal to the control device when the first shell 1 and the second shell 2 are close to each other, so that the control device controls the second magnetic module 4 to be attracted to the first magnetic module 3.

[0080] The detection member 6 is installed on the first shell 1 or the second shell 2, and is configured to detect the relative position of the first shell 1 and the second shell 2. When the foldable shell is switched from the unfolded state to the closed state, the detection member 6 sends a closing signal to the control device. After receiving the closing signal, the control device controls the coil 42 to be energized, and the second magnetic module 4 is attracted to the first magnetic module 3, thereby realizing automatic adsorption and closing of the first shell 1 and the second shell 2, and preventing the foldable shell from being accidentally unfolded in the closed state.

[0081] The detection member 6 can be a distance sensor, an angle sensor, etc. In a specific embodiment, the detection member 6 is an angle sensor, as shown in Figure 3 , the detection member 6 is configured to detect the angle of the included angle a between the first shell 1 and the second shell 2, that is, the unfolding angle of the foldable shell.

[0082] For example, when the detection member 6 detects that the included angle a between the first shell 1 and the second shell 2 gradually decreases, and the included angle a is less than or equal to a preset angle, the detection member 6 sends a closing signal to the control device. For example, the preset angle is less than 10°, for example, the preset angle is 5°. Through this setting, when the unfolding angle of the foldable shell is greater than the preset angle, the foldable shell can be maintained at this unfolding angle. When the unfolding angle of the foldable shell gradually decreases to be less than or equal to the preset angle, the first magnetic module 3 and the second magnetic module 4 will be attracted to each other, so that the foldable shell is switched to the closed state. At the same time, since the preset angle is relatively small, the first shell 1 and the second shell 2 cannot clamp the fingers when they are automatically adsorbed and closed, thereby reducing the risk of finger clamping injury.

[0083] The first magnetic module 3 and the second magnetic module 4 can be one or more.

[0084] For example, the first magnetic module 3 and the second magnetic module 4 are both multiple, and the multiple first magnetic modules 3 are distributed at intervals on the first shell 1, and the multiple second magnetic modules 4 are distributed at intervals on the second shell 2. For example Figure 1 , the first magnetic module 3 and the second magnetic module 4 are both two. Through this setting, it is ensured that the first shell 1 and the second shell 2 are reliably attracted, and the foldable shell is prevented from being accidentally unfolded in the closed state.

[0085] The embodiment of the present application also provides a foldable electronic device comprising the foldable shell provided by any of the above embodiments.

[0086] Exemplarily, the foldable electronic device is a mobile phone, a notebook computer, a tablet computer, a wearable device, a vehicle-mounted device, etc.

[0087] In this application, the terms "first" and "second" are used only for descriptive purposes, and are not to be construed as indicating or implying relative importance. The term "a plurality" means two or more, unless expressly specified otherwise.

[0088] Other embodiments of the present application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. It is intended that the present application cover any and all variations of the application that come within the scope of the present application, along with all of the equivalents thereof.
