DETAILED DESCRIPTION

[0031] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0032] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise," "include," etc. used herein indicate the presence of the features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0033] All terms used herein, including technical and scientific terms, have the meanings commonly understood by those skilled in the art, unless otherwise defined.

For example, “a system having at least one of A, B, and C” should include but is not limited to systems having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, and C, etc. When expressions such as “at least one of A, B, or C, etc.” are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art. For example, “a system having at least one of A, B, or C” should include but is not limited to systems having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, and C, etc.

[0035] It should also be noted that directional terms such as "upper," "lower," "front," "back," "left," and "right" mentioned in the embodiments are merely references to the directions in the accompanying drawings and are not intended to limit the scope of protection of this disclosure. Throughout the drawings, identical elements are represented by identical or similar reference numerals. Conventional structures or configurations will be omitted where they may cause confusion in understanding this disclosure.

[0036] When a foldable or rollable electronic device is in use, the electronic device is in an unfolded state, with the screen unfolded to ensure visibility. When in the stored state, the electronic device is in a folded or rolled state, and the screen folds or rolls along with the electronic device to reduce the size of the electronic device and improve its storage portability. In the related art, adjacent supports of at least two supports for supporting the screen are generally connected by a rotating shaft. Due to the thickness of the rotating shaft, the adjustment of the screen in the unfolded state, folded state, or rolled state is restricted, causing the screen to be damaged by tensile or compressive forces, which affects the service life of the screen.

[0037] The first aspect of the present disclosure provides an electronic device, which may be a computer, a mobile phone, or the like. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the electronic device includes a first body 1, a second body 2, and a screen 3. The second body 2 is capable of rotating relative to the first body 1. The screen 3 may include a first portion 321 and a second portion 322. The first portion 321 is disposed on the first target surface 11 of the first body 1, and the second portion 322 is disposed on the second target surface 21 of the second body 2. The target rotation axis A for the relative rotation of the first body 1 and the second body 2 may be coplanar with the first target surface 11, and / or the target rotation axis A for the relative rotation of the first body 1 and the second body 2 may be coplanar with the second target surface 21.

[0038] It should be noted that the first body 1 and the second body 2 represent supporting components for supporting the screen 3. The first body 1 and the second body 2 may be plate-shaped structures that can achieve relative rotation, and are usually used as main components of an electronic device.

[0039] Reference Figure 1 and Figure 2 As shown, the second body 2 and the first body 1 can be connected to each other by means of, but not limited to, a slider and a slide groove, a pivot, a hinge or any other connecting component to achieve relative rotation around the target rotation axis A.

[0040] Furthermore, screen 3 can be a display screen based on flexible organic light-emitting diode technology. Screen 3 includes multiple layers of materials, including a substrate, a cathode, an organic light-emitting layer, and an anode. The substrate of screen 3 can be made of a flexible material such as polyimide, which has the ability to bend and fold.

[0041] The screen 3 can be installed on the first body 1 and the second body 2 by, but not limited to, bonding, magnetic attraction, plug-in embedding or any other connection method. The screen 3 includes a first portion 321 and a second portion 322. The first portion 321 is provided on the first target surface 11 ( Figure 1 The second portion 322 is provided on the second target surface 21 ( Figure 1 the bottom surface of the second body 2).

[0042] The first target surface 11 represents a planar area that can be in contact with the first portion 321 by bonding, magnetism, plugging, embedding, etc. The first portion 321 represents a portion where the screen 3 and the first body 1 are relatively stationary.

[0043] The second target surface 21 represents a planar area that can be in contact with the second portion 322 by bonding, magnetic attraction, plugging, embedding, etc. The second portion 322 represents a portion where the screen 3 and the second body 2 are relatively stationary.

[0044] The first portion 321 and the second portion 322 are respectively disposed on the first target surface 11 of the first body 1 and the second target surface 21 of the second body 2 , thereby achieving installation and positioning of the screen 3 .

[0045] The target rotation axis A of the relative rotation between the first body 1 and the second body 2 satisfies the coplanar condition with the first target surface 11 and / or the second target surface 21 .

[0046] Reference Figure 1 and Figure 2 As shown, the target rotation axis A can be located at position A of the intersection line formed by the extension surface of the first target surface 11 and the extension surface of the second target surface 21, that is, the target rotation axis A and the first target surface 11 and the second target surface 21 meet the coplanar condition.

[0047] It is understandable that the target rotation axis A may also be located on the extension plane of the first target plane 11, but slightly offset from the extension plane of the second target plane 21. In this way, the target rotation axis A and the first target plane 11 meet the coplanar condition.

[0048] The target rotation axis A may also be located on an extension plane of the second target plane 21, but slightly offset from the extension plane of the first target plane 11. In this way, the target rotation axis A and the second target plane 21 meet the coplanar condition.

[0049] It should be noted that the user manipulates the first and second bodies 1, 2 to cause them to rotate relative to each other about the target rotation axis A. This allows the first target plane 11 and the second target plane 21 to be roughly coplanar, allowing the screen 3 to be unfolded for use. Alternatively, the first target plane 11 and the second target plane 21 can be adjusted to form an angle, allowing the electronic device and screen 3 to be folded or rolled up, thereby reducing the size of the electronic device when stored and improving portability.

[0050] According to the electronic device provided in this embodiment, the relative positions of the first body 1 and the second body 2 can be adjusted so that the electronic device and the screen 3 can be unfolded for use or folded and curled. During the relative rotation of the first body 1 and the second body 2 around the target rotation axis A, since the target rotation axis A and the first target surface 11 and / or the second target surface 21 meet the coplanar condition, the distance between the target rotation axis A and the screen 3 is shortened, so that the target rotation axis A and the screen 3 are closer. Avoid the screen 3 being subjected to tensile force or extrusion force due to the distance between the rotating axis of the relative rotation of the first body 1 and the second body 2 and the screen 3. In this way, by setting the target rotation axis A and the first target surface 11 or the second target surface 21 to meet the coplanar condition, the tensile force or extrusion force on the screen 3 can be effectively reduced, the damage to the screen 3 can be weakened, and the service life of the screen 3 can be extended.

[0051] In an exemplary embodiment, referring to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the first body 1 and the second body 2 rotate relative to each other to form a target trajectory through the mating component 4. The mating component 4 is provided on the first body 1 and / or the second body 2, or connected between the first body 1 and the second body 2, so that the first body 1 and the second body 2 have a first state in which a first angle is formed and a second state in which a second angle is formed.

[0052] The mating component 4 may include but is not limited to a slider and a slide groove, a pivot, a hinge, and the like. The mating component 4 may be provided on the first body 1, and integrally connected to the first body 1, and connected to the second body 2, so that the first body 1 and the second body 2 rotate relative to each other around the target rotation axis A. Alternatively, the mating component 4 may also be provided on the second body 2, and integrally connected to the second body 2, and connected to the first body 1, so that the first body 1 and the second body 2 rotate relative to each other around the target rotation axis A. Alternatively, the mating component 4 may also be two components, namely, a first mating component 4 and a second mating component 4, the first mating component 4 being connected to the first body 1, the second mating component 4 being connected to the second body 2, and the first mating component 4 and the second mating component 4 being connected to each other.

[0053] It can be understood that the matching component 4 is connected between the first body 1 and the second body 2, that is, the matching component 4 is connected between the side walls of the first body 1 and the second body 2 facing each other. Figure 5 and Figure 6 As shown, the mating component 4 spans across the adjacent portions of the first body 1 and the second body 2 , and both ends of the mating component 4 are mated with the adjacent ends of the first body 1 and the second body 2 .

[0054] Furthermore, the first body 1 and the second body 2 are relatively rotated around the target rotation axis A through the matching assembly 4 to adjust between the first state and the second state. In this way, double folding can be achieved.

[0055] Reference Figure 1 As shown, in the first state, the first body 1 and the second body 2 form a first angle, which ranges from -1 to 1 degree. For example, the first angle is -1, 0, 1, and so on. At this point, the first target surface 11 of the first body 1 and the second target surface 21 of the second body 2 are unfolded to form a roughly planar structure, allowing the screen 3 to be in the unfolded state to meet the user's visualization needs.

[0056] Reference Figure 2 As shown, in the second state, the first body 1 and the second body 2 form a second angle, which ranges from 120 degrees to 135 degrees. For example, the second angle is 120 degrees, 125 degrees, 130 degrees, 135 degrees, and so on. At this time, the first target surface 11 of the first body 1 and the second target surface 21 of the second body 2 are in a folded state, thereby reducing the occupied volume of the electronic device and meeting the user's need for portability.

[0057] In an exemplary embodiment, the second body 2 includes a plurality of second bodies, two of which are alternately arranged with the first body 1, and the mating component 4 is arranged between the adjacent first body 1 and the second body 2, so that the adjacent first body 1 and the second body 2 rotate relative to each other around the target rotation axis A to the first state or the second state.

[0058] Furthermore, two second bodies 2 can be provided, and one first body 1 can be provided, and the first body 1 and the second body 2 are provided alternately, that is, they are arranged in sequence as a second body, a first body and another second body in a direction perpendicular to the target rotation axis.

[0059] In this case, the mating component 4 is disposed between adjacent first bodies 1 and second bodies 2 to connect the two second bodies 2 to the first body 1 and enable the adjacent first bodies 1 and second bodies 2 to rotate relative to each other around the target rotation axis A to the first state or the second state.

[0060] This allows for a three-fold fold. In the first position, compared to the two-fold position described above, the area of ​​the plane formed by the first and second bodies 1 and 2 can be increased, thereby increasing the area of ​​the screen 3 and meeting the user's need for a larger screen 3. When the user needs to store the electronic device, the user adjusts the first and second bodies 1 and 2 to the second position, effectively reducing the length of the electronic device and the space it occupies when stored, meeting the user's need for convenient storage and improving the user experience.

[0061] In an exemplary embodiment, referring to Figure 3 、 Figure 4 、 Figure 8 and Figure 9 As shown, a plurality of first bodies 1 and second bodies 2 are provided, and the first bodies 1 and second bodies 2 are alternately connected end to end to form a support structure 7. The mating assembly 4 is provided between adjacent first bodies 1 and second bodies 2. The support mechanism 7 represents a support component for supporting the screen 3.

[0062] In the first state, the support structure 7 forms an unfolded plane for supporting the screen 3. During the adjustment from the first state to the second state, the adjacent first and second bodies 1 and 2 in the support structure 7 rotate relative to each other about the target rotation axis A toward the screen 3, so that in the second state, the support structure 7 curls and extends from the first end to the second end from the inside to the outside. The target trajectory of the relative rotation of the adjacent first and second bodies 1 and 2 from the first end to the second end of the support structure 7 decreases, causing the second angle formed by the adjacent first and second bodies 1 and 2 in the second state to increase.

[0063] The number of the first bodies 1 and the second bodies 2 and the area of ​​the screen 3 can be adjusted according to actual needs, and the first bodies 1 and the second bodies 2 can be alternately arranged in a direction perpendicular to the target rotation axis A.

[0064] Adjacent first bodies 1 and second bodies 2 are alternately connected end to end through the matching assembly 4 to form a support structure 7, so that the adjacent first bodies 1 and second bodies 2 in the support structure 7 can rotate relative to each other around the target rotation axis A to adjust between the first state and the second state.

[0065] It should be noted that by changing the size of the mating component 4, the travel of the target trajectory of relative rotation of the adjacent first and second bodies 1, 2 from the first end to the second end of the adjustment support structure 7 is successively reduced. That is, by reducing the size of the mating component 4 in the direction of the motion trajectory, the travel of the mating component 4 along the motion trajectory is reduced, thereby reducing the travel of the target trajectory of relative rotation of the adjacent first and second bodies 1, 2.

[0066] In such an embodiment, in the extension direction from the first end to the second end of the support structure 7, the size of the mating component 4 in the direction of the motion trajectory is reduced sequentially according to actual needs to reduce the stroke of the target trajectory of the relative rotation of the adjacent first body 1 and the second body 2, so that the second angle formed by the adjacent first body 1 and the second body 2 in the second state increases sequentially, thereby realizing the curling and circling extension from the inside to the outside from the first end to the second end of the support structure 7.

[0067] In an exemplary embodiment, referring to Figure 1 and Figure 2 As shown, the mating assembly 4 includes a first mating portion 41 and a second mating portion 42. The first mating portion 41 is disposed on the first body 1. The second mating portion 42 is disposed on the second body 2. The second mating portion 42 slidably engages with the first mating portion 41. The first mating portion 41 can restrict the first target rotation trajectory of the second mating portion 42, allowing the first body 1 to rotate relative to the second body 2 about the target rotation axis A.

[0068] The first matching portion 41 can be provided at one end of the first body 1 close to the second body 2 ( Figure 1 The first matching portion 41 may be an arcuate groove. That is, the first matching portion 41 may be an arcuate groove with the target rotation axis A as the center and a preset radius.

[0069] The second matching portion 42 can be provided at one end of the second body 2 close to the first body 1. The second matching portion 42 is an arcuate portion that slidably matches the arcuate groove. The arcuate portion is located in the arcuate groove and can slide along the arcuate groove.

[0070] Reference Figure 1 and Figure 2As shown, due to the sliding fit between the arcuate groove and the arcuate portion, when the first body 1 and the second body 2 are driven to rotate relative to each other from the first state to the second state under the action of an external force, the arcuate groove restricts the motion trajectory of the arcuate portion. That is, the arcuate portion slides from the right end to the left end within the arcuate groove, causing the arcuate portion to form an arcuate trajectory with a predetermined radius and a target rotation axis A as the center, thereby rotating counterclockwise along the first target rotation trajectory. This further guides the second body 2 to rotate counterclockwise relative to the first body 1 about the target rotation axis A. The reverse process is similar and will not be further described here.

[0071] In this embodiment, by providing the first mating portion 41 and the second mating portion 42, the first mating portion 41 limits the first target rotation trajectory of the second mating portion 42, so that the first body 1 rotates relative to the second body 2 about the target rotation axis A. The target rotation axis A and the first target surface 11 and / or the second target surface 21 are coplanar, thereby reducing the distance between the target rotation axis A and the screen 3, bringing the target rotation axis A closer to the screen 3. This can effectively reduce the tensile or compressive forces on the screen 3, reduce damage to the screen 3, and extend the service life of the screen 3.

[0072] In an exemplary embodiment, referring to Figure 1 and Figure 2 As shown, the first matching portion 41 can be provided at one end of the first body 1 close to the second body 2 ( Figure 1 The second matching portion 42 can be provided at one end of the second body 2 close to the first body 1 ( Figure 1 the right end of the second body 2).

[0073] It can be understood that the positions of the first matching portion 41 and the second matching portion 42 can be interchanged, that is, the first matching portion 41 can be set at one end of the second body 2 close to the first body 1, and the second matching portion 42 can be set at one end of the first body 1 close to the second body 2.

[0074] In this way, the adjacent first bodies 1 and second bodies 2 are connected to each other through the first matching portion 41 and the second matching portion 42 that are slidably matched, so that double folding can be achieved.

[0075] In an exemplary embodiment, the second body 2 includes a plurality of second bodies 2 , and two of the plurality of second bodies 2 are alternately arranged with the first body 1 .

[0076] In the first state, the first body 1 and the second body 2 are arranged in the same direction of extension, for example, the direction of extension can be horizontally from left to right. The first end (the left end of the first body 1) and the second end (the right end of the first body 1) of the first body 1 are respectively provided with a first mating portion 41 and a second mating portion 42. The second body 2 located upstream (the second body 2 located to the left of the first body 1) is provided with the second mating portion 42 at its end proximal to the first body 1 (the right end of the second body), and the second body 2 located downstream (the second body 2 located to the right of the first body 1) is provided with the first mating portion 41 at its end proximal to the first body 1 (the left end of the second body 2).

[0077] In this way, the first body 1 and the two second bodies 2 are connected to each other through the first matching parts 41 and the second matching parts 42 provided between adjacent first bodies 1 and second bodies 2 and slidingly matched with each other, so that three-folding can be achieved.

[0078] In an exemplary embodiment, referring to Figure 1 、 Figure 2 and Figure 4 As shown, a plurality of first and second bodies 1 and 2 are provided. In a first state, a first mating portion 41 and a second mating portion 42 are respectively provided at the first end (the left end of the first and second bodies 1 and 2) and the second end (the right end of the first and second bodies 1 and 2) of the first and second bodies 1 and 2 in the same arrangement and extension direction, and the first mating portion 41 of the first body 1 and the second mating portion 42 of the adjacent second body 2 are slidably engaged, and the second mating portion 42 of the first body 1 and the first mating portion 41 of the adjacent second body 2 are slidably engaged.

[0079] In this way, a plurality of adjacent first bodies 1 and second bodies 2 are connected to each other through the first matching parts 41 and the second matching parts 42 that are slidably matched, thereby achieving multi-folding.

[0080] It is understood that, in the direction in which the first and second bodies 1 and 2 extend to each other, the end of the first body 1 located at the endmost, away from the adjacent second body 2, may be provided with the first mating portion 41 or the second mating portion 42, or the first mating portion 41 or the second mating portion 42 may be omitted. The end of the second body 2 located at the endmost, away from the first body 1, may be provided with the first mating portion 41 or the second mating portion 42, or the first mating portion 41 or the second mating portion 42 may be omitted. Thus, depending on actual needs, the first mating portion 41 and the second mating portion 42 at the end in the direction in which the first and second bodies 1 and 2 extend to each other may be omitted, thereby reducing costs.

[0081] In an exemplary embodiment, referring to Figure 1 and Figure 2As shown, the electronic device includes a limiting mechanism 5. In a first state, the limiting mechanism 5 generates resistance against relative sliding of the first mating portion 41 and the second mating portion 42 to maintain the first state. During the adjustment from the first state to the second state, an external force is applied to counteract the resistance of the limiting mechanism 5 to allow the second mating portion 42 to slide with the first mating portion 41 and adjust to the second state.

[0082] Specifically, the limiting mechanism 5 may include but is not limited to a snap assembly, a torsion spring, a pin, etc., which is determined according to actual needs.

[0083] Reference Figure 1 As shown, in the first state, the limiting mechanism 5 can form a resistance against the relative sliding of the first matching part 41 and the second matching part 42 through the locking force of the snap assembly, the elastic force of the torsion spring or the limiting resistance of the pin, thereby preventing the first matching part 41 and the second matching part 42 from sliding relative to each other, thereby maintaining the first state.

[0084] During the adjustment process from the first state to the second state, an external force is applied to counteract the resistance of the limiting mechanism 5, that is, a torque is applied to the ends of the first body 1 and the second body 2 that are separated from each other, causing them to move toward the screen, and a torque is applied to the ends of the first body 1 and the second body 2 that are close to each other, causing them to move away from the screen. For example, an external force greater than the snap-fitting force of the snap assembly, or greater than the elastic force of the torsion spring, or an external force capable of pulling out a pin can be applied to the first body 1 and the second body 2. In this way, the applied external force can counteract the resistance of the limiting mechanism 5 to the first mating portion 41 and the second mating portion 42, allowing the second mating portion 42 to slide with the first mating portion 41, so that the first body 1 rotates relative to the second body 2 about the target rotation axis A, thereby adjusting from the first state to the second state.

[0085] In this embodiment, the limiting mechanism 5 forms a resistance against the relative sliding of the first mating portion 41 and the second mating portion 42 to maintain the first state, thereby maintaining the screen 3 in the unfolded state, allowing the user to view the screen 3 and achieve visualization of the screen 3. This prevents the electronic device from being accidentally subjected to an external force that is less than the resistance of the limiting mechanism 5, causing the first body 1 to rotate relative to the second body 2, thereby causing the screen 3 to fold or bend, thereby affecting the user experience.

[0086] Furthermore, when the user needs to store and fold the electronic device, by applying an external force greater than the resistance of the limiting mechanism 5, the first body 1 and the second body 2 can be rotated relative to each other, thereby adjusting to the second state, realizing the folding or bending of the electronic device, reducing the volume occupied by the electronic device, and meeting the needs of storage portability.

[0087] In an exemplary embodiment, referring to 1 and Figure 2As shown, the limiting mechanism 5 includes a recessed portion 51 and a raised portion 52. The recessed portion 51 is provided on the first body 1. The raised portion 52 is provided on the second body 2 and protrudes outwards for engaging with or separating from the recessed portion 51.

[0088] In the first state, the recessed portion 51 and the raised portion 52 engage to form resistance against relative sliding of the first and second mating portions 41, 42, and engage with the mutually abutting first ends of the first and second mating portions 41, 42, maintaining the first state. In the second state, the recessed portion 51 and the raised portion 52 separate, the first end of the first mating portion 41 contacts the second mating portion 42, and the second ends of the first mating portion 41 and the second ends of the second mating portion 42 abut against each other, preventing the second body 2 from rotating relative to the first body 1, maintaining the second state.

[0089] Specifically, the recessed portion 51 can be provided on the first body 1 or on other components connected to the first body 1. The raised portion 52 can be provided on the first body 1 or on other components connected to the first body 1, depending on actual needs.

[0090] The width of the recessed portion 51 is smaller than the maximum width of the raised portion 52. Under the action of an external force, the recessed portion 51 can slightly deform to allow the raised portion 52 to pass through the recessed portion 51 and enter the recessed portion 51, thereby forming a snap connection with the recessed portion 51, or to allow the raised portion 52 to pass through the recessed portion 51 and detach from the recessed portion 51.

[0091] Furthermore, under the action of an external force, the protrusion 52 can move with the second body 2 and be inserted into the recess 51. During the insertion into the recess 51, the protrusion 52 causes the diameter of the recess 51 to slightly deform, thereby increasing the diameter to allow the protrusion 52 to be inserted into the recess 51. Subsequently, the recess 51 returns to its original position, causing the protrusion 52 to be stuck in the recess 51, forming a resistance that prevents the first body 1 from rotating relative to the second body 2.

[0092] An external force greater than the resistance formed by the recessed portion 51 and the raised portion 52 is applied to the first body 1 and the second body 2, so that the raised portion 52 can move with the second body 2 and disengage from the recessed portion 51 to separate from the recessed portion 51, thereby removing the restrictions on the first body 1 and the second body 2 and allowing the first body 1 to rotate around the target rotation axis A relative to the second body 2.

[0093] Furthermore, in the first state, the recessed portion 51 is engaged with the raised portion 52 to form a resistance to prevent the first body 1 from rotating relative to the second body 2. Figure 1 the right end of the first matching portion 41) and the first end of the second matching portion 42 ( Figure 1The right end of the second matching portion 42 in the middle is in contact with each other, restricting the ends of the first body 1 and the second body 2 that are away from each other from rotating in a direction away from the screen 3, thereby maintaining the first state.

[0094] During the adjustment from the first state to the second state, an external force greater than the resistance formed by the recessed portion 51 and the raised portion 52 is applied to the first body 1 and the second body 2, so that the raised portion 52 is separated from the recessed portion 51, thereby removing the restriction on the first body 1 and the second body 2. Figure 2 The right end of the first matching portion 41) contacts the second matching portion 42, and the second end of the first matching portion 41 ( Figure 2 The left end of the first matching portion 41) and the second end of the second matching portion 42 ( Figure 1 The left end of the second matching portion 42 in the middle abuts against each other to prevent the second body 2 from rotating relative to the first body 1, so as to maintain the second state.

[0095] According to an embodiment of the present disclosure, by setting a limit mechanism 5, it is convenient for the user to adjust the first body 1 and the second body 2 to rotate relative to each other to the first state or the second state, and maintain them in the first state or the second state, so that the user can adjust the electronic device according to his own needs and meet the user's needs for convenience of use and storage.

[0096] In an exemplary embodiment, the first body 1 and / or the second body 2 extends outward to form a connecting portion 6, which forms a first mating portion 41. In the first state, the connecting portions 6 between adjacent first bodies 1 and second bodies 2 abut against each other to form an abutting surface 61.

[0097] Reference Figure 1 and Figure 2 As shown, in the case where one first body 1 and one second body 2 are provided, the end of the first body 1 close to the second body 2 ( Figure 1 The left end of the first body 1 in the middle extends toward the direction close to the second body 2 to form a connecting portion 6, so that the first matching portion 41 formed on the side of the connecting portion 6 close to the screen 3 is matched with the second matching portion 42 of the second body 2. The end of the second body 2 away from the first body 1 ( Figure 1 The left end of the second body 2 in the middle can be provided with a connecting portion 6, or it can be omitted, depending on actual needs.

[0098] It is understandable that the positions of the connecting portion 6 and the second matching portion 42 can be interchanged, that is, the connecting portion 6 is provided on the second body 2 , which will not be described in detail here.

[0099] In the case where the second body 2 includes a plurality of second bodies 2, two of the plurality of second bodies 2 are alternately arranged with the first body 1, and in the case where the first body 1 and the second body 2 are provided in plurality, the first end ( Figure 1 The first body 1 and the left end of the second body 2 are both provided with a connecting portion 6, and the second end ( Figure 1 A second matching portion 42 is provided at the right end of each of the first body 1 and the second body 2.

[0100] Furthermore, in the first state, the connecting parts 6 between the adjacent first bodies 1 and second bodies 2 abut against each other to form an abutment surface 61, thereby generating resistance that prevents the end of the first body 1 and the second body 2 away from the target rotation axis A from continuing to rotate in the direction away from the screen, further improving the stability of the first body 1 and the second body 2 in maintaining the first state.

[0101] In an exemplary embodiment, the side of the connecting portion 6 facing away from the screen ( Figure 1 The top surface of the middle connecting portion 6 forms a naturally transitioning curved surface 62 with the abutting surface 61. By providing the naturally transitioning curved surface 62, the outer contour of the connecting portion 6 is free from sharp edges and corners, reducing the risk of scratches and bumps on the electronic device, and improving the user experience.

[0102] Furthermore, by providing the arc surface 62, the space occupied by the outer contour of the connecting portion 6 can be reduced, thereby further reducing the volume of the electronic device in the second state and improving the portability of the electronic device.

[0103] In an exemplary embodiment, the recessed portion 51 and the raised portion 52 are respectively provided on two adjacent abutment surfaces 61, that is, the recessed portion 51 and the raised portion 52 are respectively provided on the abutment surfaces 61 on opposite sides of the same connecting portion 6. In this way, the recessed portion 51 and the raised portion 52 are integrated into the connecting portion 6 to facilitate integrated processing and molding, thereby improving processing and production efficiency.

[0104] In an exemplary embodiment, referring to Figure 5 and Figure 6As shown, the mating assembly 4 includes a first mating portion 41, a second mating portion 42 and an adapting portion 43. The first mating portion 41 is provided on the first body 1. The second mating portion 42 is provided on the second body 2. The adapting portion 43 includes a first adapting cavity 431 and a second adapting cavity 432. The first adapting cavity 431 is rotationally engaged with the first mating portion 41. The second adapting cavity 432 is movably engaged with the second mating portion 42. The adapting portion 43 is capable of limiting the second target rotation trajectory of the relative movement of the first mating portion 41 and the second mating portion 42, so that the first body 1 rotates relative to the second body 2 around the target rotation axis A. The adapting portion 43 rotates relative to the first body 1 and the second body 2, so that the second adapting cavity 432 rotates in a direction toward the second body 2.

[0105] Reference Figure 5 and Figure 6 As shown, the first matching portion 41 can be provided at one end of the first body 1 close to the second body 2 ( Figure 5 The left end of the first body 1 in the figure). It is understandable that the first matching portion 41 can also be set at other positions of the first body 1 or other components connected to the first body 1. The second matching portion 42 can be set at one end of the second body 2 close to the first body 1 ( Figure 5 It is understandable that the second matching portion 42 may also be provided at other positions of the second body 2 or at other components connected to the second body 2.

[0106] Reference Figure 5 and Figure 6 As shown, the two ends of the adapting portion 43 are bent toward the first mating portion 41 and the second mating portion 42 to form a first adapting cavity 431 that rotates with the first mating portion 41 and a second adapting cavity 432 that flexibly engages with the second mating portion 42. By providing the first and second adapting cavities 431, 432, the first mating portion 41 is restricted from rotating relative to the adapting portion 43 about the first mating cavity 431, while the second mating portion 42 simultaneously deflects relative to the adapting portion 43, achieving a second target rotation trajectory in which the first and second mating portions 41, 42 simultaneously rotate about the target rotation axis, thereby driving the first body 1 to rotate relative to the second body 2 about the target rotation axis A, thereby adjusting to the first state or the second state.

[0107] During the process of adjusting from the first state to the second state, the adapter part 43 rotates relative to the first body 1 and the second body 2, and the second adapter cavity 432 rotates in a direction toward the second body 2, so as to further reduce the space occupied by the outer contour formed by the adapter part 43 when adjusting to the second state, thereby reducing the volume of the electronic device and further improving the convenience of carrying the electronic device.

[0108] In an exemplary embodiment, referring to Figure 5As shown, the first matching portion 41 can be provided at one end of the first body 1 close to the second body 2 ( Figure 5 The second matching portion 42 is provided at one end of the second body 2 close to the first body 1 ( Figure 5 The adapting portion 43 is arranged between the adjacent first matching portion 41 and the second matching portion 42.

[0109] It is understandable that the positions of the first mating portion 41 and the second mating portion 42 can be interchanged, that is, the first mating portion 41 can be provided at an end of the second body 2 close to the first body 1, and the second mating portion 42 can be provided at an end of the first body 1 close to the second body 2. The adapting portion 43 is provided between adjacent first mating portions 41 and second mating portions 42, and is mated with the first mating portion 41 and the second mating portion 42, respectively.

[0110] In this way, the adjacent first bodies 1 and second bodies 2 are connected to each other through the first matching portion 41 , the second matching portion 42 and the adapting portion 43 , thereby achieving double folding.

[0111] In an exemplary embodiment, the second body 2 includes a plurality of second bodies 2 , and two of the plurality of second bodies 2 are alternately arranged with the first body 1 .

[0112] In the first state, the first body 1 and the second body 2 are arranged in the same extending direction, for example, the extending direction can be horizontally from left to right. The first end (the left end of the first body 1) and the second end (the right end of the first body 1) of the first body 1 are respectively provided with a first mating portion 41 and a second mating portion 42. The second body 2 located upstream (the second body 2 located to the left of the first body 1) is provided with the second mating portion 42 at one end near the first body 1 (the right end of the second body). The second body 2 located downstream (the second body 2 located to the right of the first body 1) is provided with the first mating portion 41 at one end near the first body 1 (the left end of the second body 2). An adaptor portion 43 is provided between each set of adjacent first mating portions 41 and second mating portions 42, and is respectively adapted to engage with the first mating portion 41 and the second mating portion 42.

[0113] In this way, the first body 1 and the two second bodies 2 are connected to each other through the first matching portion 41 , the second matching portion 42 and the adapting portion 43 provided between the adjacent first bodies 1 and the second bodies 2 , so as to achieve triple folding.

[0114] Multiple first bodies 1 and second bodies 2 are provided. In the first state, first matching portions 41 and second matching portions 42 are respectively provided at the first end (the left end of the first body 1 and the second body 2) and the second end (the right end of the first body 1 and the second body 2) of the same arrangement extension direction of the first body 1 and the second body 2, and the adapting portion 43 is provided between adjacent first matching portions 41 and second matching portions 42.

[0115] In this way, a plurality of adjacent first bodies 1 and second bodies 2 are connected to each other through the first matching portion 41 , the second matching portion 42 and the adapting portion 43 , thereby achieving multi-folding.

[0116] In an exemplary embodiment, adjacent fitting portions 43 abut against each other to form contact portions 433. Thus, the abutment of adjacent fitting portions 43 can produce a support and limit effect, reducing the risk of separation and gap formation between the first body and the second body in the first state, and also achieving a compact layout, avoiding space waste, and reducing the size of the electronic device.

[0117] In an exemplary embodiment, referring to Figure 5 As shown, the adapting portion 43 faces one side of the screen 3 ( Figure 5 The bottom surface of the middle adapting portion 43) forms a first curved surface 434 with a natural transition to the contact portion 433. This allows the distance between the first curved surfaces 434 of adjacent adapting portions 43 to gradually increase from top to bottom. During the adjustment process from the first state to the second state, the first curved surfaces 434 of adjacent adapting portions 43 form a clearance space, allowing for relative rotation of adjacent adapting portions 43, to avoid the risk of interference caused by abutment between adjacent adapting portions 43.

[0118] In an exemplary embodiment, referring to Figure 5 、 Figure 6 and Figure 7 As shown, the adapting portion 43 faces away from the side of the screen 3 ( Figure 5 The top surface of the middle connecting portion 6 forms a naturally transitioning second curved surface 435 with the contact portion 433. By providing the naturally transitioning second curved surface 435, the outer contour of the connecting portion 6 is free of sharp edges and corners, reducing the risk of scratches and bumps on the electronic device, and improving the user experience.

[0119] Furthermore, by providing the second curved surface 435 , the space occupied by the outer contour of the connecting portion 6 can be reduced, thereby further reducing the volume of the electronic device in the second state and improving the portability of the electronic device.

[0120] In an exemplary embodiment, referring to Figure 5 and Figure 6 As shown, the first matching portion 41 and the second matching portion 42 each include a support arm 411 and a terminal end 412. The first end ( Figure 5 The bottom end of the middle support arm 411 is located on the side of the first body 1 or the second body 2 facing away from the screen 3 ( Figure 5 The end 412 is provided at the second end of the support arm 411 opposite to the first end ( Figure 5The end 412 includes an arc portion 4121 rotatably engaged with the adapting portion 43 and a connecting arm 4122 connected between the arc portion 4121 and the arm 411 .

[0121] The length of the connecting arm 4122 of the second matching portion 42 is greater than that of the connecting arm 4122 of the first matching portion 41 , and the arc portion 4121 of the first matching portion 41 is rotationally engaged with the first adapting cavity 431 .

[0122] In the first state, the first end of the second adapting cavity 432 ( Figure 5 The second end of the second fitting cavity 432 is in contact with the arc portion 4121 of the second matching portion 42. In the second state, the second end of the second fitting cavity 432 is opposite to the first end ( Figure 5 The left end of the second adapting cavity 432 in the middle abuts against the arc portion 4121 of the second matching portion 42, and the adapting portion 43 abuts against the connecting arm 4122 of the first matching portion 41 and the connecting arm 4122 of the second matching portion 42.

[0123] The first end of the support arm 411 can be connected to the first body 1 or the second body 2 and extend toward the adapting portion 43. The end 412 can be provided at the second end of the support arm 411. The arc portion 4121 of the end 412 of the first mating portion 41 is rotatably engaged with the first adapting cavity 431. The arc portion 4121 of the end 412 of the second mating portion 42 is slidably engaged with and rotatably contacts the second adapting cavity 432.

[0124] Reference Figure 5 As shown, in the first state, the first end of the second adapting cavity 432 abuts the arc portion 4121 of the second matching portion 42. At this time, the first body 1 and the second body 2 abut each other, and the first target surface 11 and the second target surface 21 are roughly coplanar, so that the screen 3 is in the unfolded state.

[0125] When adjusting from the first state to the second state, an external force is applied to the first body 1 and the second body 2, so that the first body 1 rotates relative to the second body 2 around the target rotation axis A. At the same time, the arc portion 4121 of the end 412 of the second matching portion 42 slides toward the second end of the second adapting cavity 432 and rotates relative to the second adapting cavity 432 until it moves to the second end of the second adapting cavity 432. At this time, the adapting portion 43 abuts against the connecting arm 4122 of the first matching portion 41 and the connecting arm 4122 of the second matching portion 42, as shown in FIG. Figure 6 In the second state, the screen 3 is in a folded and bent state.

[0126] In such an embodiment, by setting the adapter part 43, the first matching part 41 and the second matching part 42, the second target rotation trajectory of the relative movement of the first matching part 41, the second matching part 42 and the adapter part 43 is limited, so that the first body 1 and the second body 2 abut against each other and rotate relative to each other around the target rotation axis A, thereby adjusting between the first state and the second state, which is convenient for adjusting the screen 3 of the electronic device to an unfolded state or a folded and bent state according to the actual needs of the user, and the operation is convenient.

[0127] In an exemplary embodiment, referring to Figure 5 and Figure 6 As shown, the electronic device includes a restraint mechanism 53 disposed in the second fitting cavity 432 of the fitting portion 43. In the first state and the second state, the restraint mechanism 53 cooperates with the fitting portion 43 to generate resistance that prevents the second fitting portion 42 from moving relative to the second fitting cavity 432, thereby maintaining the first state and the second state.

[0128] When adjusting between the first state and the second state, an external force is applied to counteract the resistance of the constraint mechanism 53 so that the second matching portion 42 moves relative to the second adapting cavity 432 to allow the first body 1 and the second body 2 to rotate relative to the first state or the second state.

[0129] The restraint mechanism 53 includes but is not limited to a snap-fit ​​portion, a telescopic portion, a clamping assembly, etc., and is specifically determined according to actual needs.

[0130] Reference Figure 5 and Figure 6 As shown, in the first state and the second state, the restraint mechanism 53 cooperates with the adapter portion 43 to press and clamp the second matching portion 42, thereby generating resistance to prevent the second matching portion 42 from moving relative to the second adapter cavity 432, thereby maintaining the first state and the second state.

[0131] When adjusting between the first state and the second state, an external force greater than the resistance of the constraint mechanism 53 can be applied to the first body 1 and the second body 2, so that the second matching part 42 moves relative to the second adapter cavity 432, thereby causing the first body 1 to rotate relative to the second body 2 around the target rotation axis A to adjust from the first state to the second state.

[0132] In this embodiment, the restraining mechanism 53 forms a resistance against sliding of the second mating portion 42 relative to the second adapting cavity 432, thereby maintaining the first state, thereby maintaining the screen 3 in the unfolded state, allowing the user to view the screen 3 and achieve visualization of the screen 3. This prevents the electronic device from being accidentally subjected to an external force less than the resistance of the restraining mechanism 53, causing the first body 1 to rotate relative to the second body 2, thereby causing the screen 3 to fold or bend, thereby affecting the user experience.

[0133] Furthermore, when the user needs to store and fold the electronic device, by applying an external force greater than the resistance of the restraint mechanism 53, the first body 1 and the second body 2 can be rotated relative to each other, thereby adjusting to the second state, realizing the folding or bending of the electronic device, reducing the volume occupied by the electronic device, and meeting the needs of storage portability.

[0134] In an exemplary embodiment, referring to 5 and Figure 6 As shown, the restraint mechanism 53 may include a first limiting portion 531 and a second limiting portion 532 .

[0135] The first limiting portion 531 can be provided at the first end of the second adapting cavity 432 ( Figure 5 The first caliber formed by the first limiting portion 531 and the adapting portion 43 is engaged with the arc portion 4121 of the second matching portion 42 to prevent the second matching portion 42 from moving relative to the second adapting cavity 432 and maintain the first state, or under the action of a preset external force, the first caliber increases and allows the arc portion 4121 of the second matching portion 42 to move to the second end of the second adapting cavity 432 ( Figure 5 The left end of the second adapting cavity 432 in the middle).

[0136] The second limiting portion 532 can be arranged at the second end of the second adapting cavity 432. The second caliber formed by the second limiting portion 532 and the adapting portion 43 is snap-fitted with the arc portion 4121 of the second matching portion 42 to prevent the second matching portion 42 from moving relative to the second adapting cavity 432 and maintain the second state, or under the action of a preset external force, the second caliber increases and allows the arc portion 4121 of the second matching portion 42 to move to the first end of the second adapting cavity 432.

[0137] The diameter of the second fitting cavity 432 can match the end 412 of the second matching portion 42, allowing the end 412 of the second matching portion 42 to slide within the second fitting cavity 432. The first and second limiting portions 531, 532 are formed by the inner wall of the second fitting cavity 432 of the matching portion 43 protruding toward the second fitting cavity 432, thereby reducing the diameter of the second fitting cavity 432 at the positions of the first and second limiting portions 531, 532 to engage with the arc portion 4121 of the second matching portion 42.

[0138] It should be noted that the first limiting portion 531 and the first end of the second adapting cavity 432 can be spaced apart to form a space for accommodating the arc portion 4121 of the second adapting portion 43. The second limiting portion 532 and the second end of the second adapting cavity 432 can be spaced apart to form a space for accommodating the arc portion 4121 of the second adapting portion 43.

[0139] In the first state or the second state, the arc portion 4121 of the second adapter part 43 abuts against the first limiting portion 531 and the second limiting portion 532 respectively. Since the diameter of the second adapter cavity 432 at the position of the first limiting portion 531 and the second limiting portion 532 is smaller than the diameter of the arc portion 4121 of the second adapter part 43, a resistance is generated to prevent the second matching part 42 from sliding relative to the second adapter cavity 432, thereby maintaining the first state or the second state.

[0140] During the adjustment process between the first state and the second state, an external force greater than the resistance of the constraint mechanism 53 is applied to the first body 1 and the second body 2, and the adapter 43 undergoes a slight deformation, thereby increasing the diameter of the second adapter cavity 432 located at the position of the first limiting portion 531 or the second limiting portion 532, thereby allowing the second matching portion 42 to slide relative to the second adapter cavity 432 to adjust to the first state or the second state.

[0141] According to an embodiment of the present disclosure, by providing a restraint mechanism 53, it is convenient for the user to adjust the first body 1 and the second body 2 to rotate relative to each other to the first state or the second state, and maintain them in the first state or the second state, so that the user can adjust the electronic device according to his or her own needs and meet the user's needs for convenience of use and storage.

[0142] In an exemplary embodiment, referring to 2 and Figure 6 As shown, the screen 3 includes a first portion detachable from the first body 1 and / or the second body 2 and a second portion in contact with the first body 1 and the second body 2 , wherein the second portion includes a first portion 321 and a second portion 322 .

[0143] In the first state, the neutral layer of the first portion has a first length of L, where the neutral layer represents a transition layer where the force on the first portion in the thickness direction is zero. In the second state, the first portion is separated from the first body 1 and / or the second body 2 and bent, and the neutral layer of the first portion has a second length of L, where the first length L is the same as the second length L.

[0144] The screen 3 can be flexible and continuously provided. The screen 3 has a certain thickness. The neutral layer represents a transition layer in which the force applied to the screen 3 in the thickness direction is zero.

[0145] The first portion 321 of the screen 3 contacts and cooperates with the first target surface 11 of the first body 1, and the second portion 322 of the screen 3 contacts and cooperates with the second target surface 21 of the second body 2. The first portion of the screen 3 is provided where the first body 1 and the second body 2 are connected.

[0146] In the first state, the first target surface 11 of the first body 1 is roughly coplanar with the second target surface 21 of the second body 2, so that the screen 3 is in the unfolded state, the first part and the second part of the screen 3 are roughly coplanar, and the first length of the neutral layer of the first part is L.

[0147] During adjustment from the first state to the second state, the first body 1 rotates relative to the second body 2 around the target rotation axis A, allowing the first portion to separate from the first body 1 and / or the second body 2 and naturally transition and bend. In the second state, the first portion is roughly arc-shaped.

[0148] According to an embodiment of the present disclosure, since the target rotation axis A of the relative rotation of the first body 1 and the second body 2 satisfies the coplanar adjustment with the first target surface 11 and / or the second target surface 21, the distance between the target rotation axis A and the screen 3 is effectively reduced, and the tensile force or extrusion force exerted on the screen 3 during the adjustment process between the first state and the second state is effectively reduced, so that the second length L of the neutral layer of the first part in the second state is the same as the first length L.

[0149] In an exemplary embodiment, the electronic device may further include at least one set of battery compartments 8 disposed at the ends of the support structure 7 , wherein in the second state, the area of ​​the first end of the support structure 7 forms a cavity for accommodating the battery compartments 8 .

[0150] Battery compartments 8 are used to house batteries and optimize heat dissipation in electronic devices. Battery compartments 8 are provided at the ends of support structure 7, including but not limited to hinges and snap-on assemblies. Battery compartments 8 can be provided in one or two groups, located at one or both ends of support structure 7.

[0151] In this embodiment, since the support structure 7 curls and extends from the first end to the second end from the inside out, the area at the first end of the support structure 7 forms a space for accommodating the battery compartment 8. In this way, the battery compartment 8 can utilize the space formed by the first end of the support structure 7, further improving the space utilization of the electronic device, reducing the size of the electronic device, and improving the storage portability of the electronic device.

[0152] In one exemplary embodiment, as shown in FIG3 , a rotatable bracket 9 is provided on the side of the first body 1 or the second body 2 facing away from the screen 3. The bracket 9 includes, but is not limited to, being mounted to the first body 1 or the second body 2 via a pivot, hinge assembly, or other rotating assembly to support the electronic device on a base surface in a first state. The angle between the screen 3 and the base surface can be adjusted to suit the user's needs, thereby enhancing the user experience.

[0153] The second aspect of the present disclosure provides an electronic device, referring to Figure 5 、 Figure 6 and Figure 7As shown, the electronic device includes a first body 1, a second body 2 and a screen 3. The first body 1 is provided with a first track surface 12. The second body 2 is provided with a second track surface 22 that abuts against the first track surface 12, so that the second body 2 can rotate around the target rotation axis A relative to the first body 1. The screen 3 may include a first part and a second part. The first part is provided on the first target surface 11 of the first body 1, and the second part is provided on the second target surface 21 of the second body 2. The first target surface 11 is connected to the first track surface 12, and the second target surface 21 is connected to the second track surface 22. The target rotation axis A is located on the first track surface 12 and / or the second track surface 22.

[0154] Reference Figure 5 As shown, in the first state, the sidewalls of the first body 1 and the second body 2 contact each other to form a contact surface. The contact surface of the first body 1 and the first target surface 11 can be connected by a smoothly transitioned arc surface to form a first track surface 12. Similarly, the contact surface of the second body 2 and the second target surface 21 can be connected by a smoothly transitioned arc surface to form a second track surface 22.

[0155] The first track surface 12 and the second track surface 22 represent contact surfaces during the relative motion of the first body 1 and the second body 2 , and may be arc surfaces with a specific curvature to guide the relative rotational motion trajectory of the first body 1 and the second body 2 .

[0156] Reference Figure 6 and Figure 7 As shown, during the relative rotation of the first body 1 and the second body 2 under the action of an external force, since the first track surface 12 and the second track surface 22 are arc surfaces, the first track surface 12 of the first body 1 and the second track surface 22 of the second body 2 abut against each other to form a virtual contact line, that is, the target rotation axis A.

[0157] When the second body 2 moves relative to the first body 1 , the second track surface 22 rotates and rolls relative to the first track surface 12 , so that the contact line moves along the first track surface 12 and the second track surface 22 , that is, the first track surface 12 and the second track surface 22 define the motion trajectory of the target rotation axis A.

[0158] It is understandable that, referring to Figure 1 As shown, in the first state, the facing sidewalls of the first body 1 and the second body 2 can form a contact surface. The contact surface of the first body 1 and the first target surface 11 can be connected by a smoothly transitioned arc surface to form a first trajectory surface (not shown). Similarly, the contact surface of the second body 2 and the second target surface 21 can be connected by a smoothly transitioned arc surface to form a second trajectory surface (not shown), with the target rotation axis A located on the first trajectory surface and / or the second trajectory surface.

[0159] In such an embodiment, the target rotation axis A is located on the first track surface 12 and / or the second track surface 22, thereby reducing the distance between the target rotation axis A and the screen 3, avoiding the screen 3 being subjected to tensile force or extrusion force due to the distance between the rotating axis of the relative rotation of the first body 1 and the second body 2 and the screen 3, thereby reducing damage to the screen 3 and extending the service life of the screen 3.

[0160] Based on similar inventive concepts, this electronic device and the first body and the second body in the above-mentioned embodiment all feature a supporting component for supporting the screen 3. The first body 1 rotates around the target rotation axis A relative to the second body 2. This electronic device has similar or identical features to the above-mentioned embodiment, and also has similar or identical functions based on these features. The target rotation axis A for the relative rotation of the first body 1 and the second body 2 can meet the coplanar condition with the second target surface 21, and the target rotation axis A can also be located on the first trajectory surface and / or the second trajectory surface. For this reason, it will not be described in detail.

[0161] According to the electronic device provided in this embodiment, the relative positions of the first body 1 and the second body 2 can be adjusted so that the electronic device and the screen 3 can be unfolded for use or folded and curled. During the relative rotation of the first body 1 and the second body 2 around the target rotation axis A, since the target rotation axis A and the first target surface 11 or the second target surface 21 meet the coplanar condition, the distance between the target rotation axis A and the screen 3 is reduced, so that the target rotation axis A and the screen 3 are infinitely close to coincide with each other. This avoids the screen 3 being subjected to tensile force or extrusion force due to the distance between the rotating axis of the relative rotation of the first body 1 and the second body 2 and the screen 3. In this way, by setting the target rotation axis A and the first target surface 11 or the second target surface 21 to meet the coplanar condition, the tensile force or extrusion force on the screen 3 can be effectively reduced, the damage to the screen 3 can be weakened, and the service life of the screen 3 can be extended.

Although each embodiment has been described separately above, this does not mean that the measures in each embodiment cannot be used in combination to advantage.
