Description

Technical Field

[0001] This application relates to the field of foldable electronic products technology, and in particular to a shielding component, a folding mechanism, and an electronic device. Background Technology

[0002] In recent years, flexible displays have been widely used in various foldable electronic devices due to their lightweight, thinness, and durability. Foldable electronic devices also include folding devices to support the flexible displays. These folding devices typically consist of two housings and a folding mechanism connecting the two housings. The two housings fold or unfold relative to each other through the movement of the folding mechanism, which in turn causes the flexible displays to fold or unfold.

[0003] There is a gap between the folding mechanism and the edge of the flexible display screen. In the prior art, a shielding component is used to cover the gap. However, when the electronic device is dropped, the shielding component is prone to impact with the flexible display screen, which affects the service life of the electronic device. Utility Model Content

[0004] This application provides a shielding component, a folding mechanism, and an electronic device. The shielding component within the folding mechanism has high connection reliability with the main shaft, thereby improving the service life of the electronic device.

[0005] In a first aspect, this application provides a shielding member. The shielding member is applied to a folding mechanism and is mounted on the main shaft of the folding mechanism. The end of the main shaft is provided with a first groove. The shielding member includes a second part and a first protrusion. The second part is disposed in the first groove, and the first protrusion is fixed to the second part. Along a first direction, the projection of the first protrusion overlaps with at least a portion of the second part, wherein the first direction is the direction in which the first protrusion points to the second part.

[0006] By setting the projection of the first protrusion to overlap with at least a portion of the second portion, when the shielding member is installed in the first groove within the spindle, the first protrusion is located between the second portion and the first groove. This helps to reduce the gap between the second portion and the first groove, reduce the space in which the shielding member can move within the first groove, and thus improve the reliability of the connection when the shielding member is installed in the first groove.

[0007] In some possible implementations, the shielding element includes a first part, the first part and the second part are fixedly connected, a first protrusion is disposed at one end of the second part facing the first part, and at least part of the first part is disposed on the spindle.

[0008] Understandably, when the rotating shaft mechanism falls, the first protrusion will abut against the groove wall of the first groove to block the rotation of the shielding component. By setting the first protrusion at the end of the second part away from the first part, the torque of the abutment force when the shielding component rotates is increased, thereby effectively reducing the amount of rotation of the shielding component and improving the reliability of the electronic device.

[0009] In some possible implementations, there are two first bumps, which are spaced apart along the second direction and are respectively close to the two ends of the second part in the second direction, wherein the second direction is set at an angle to the first direction.

[0010] In some possible implementations, the size of the first bump in the second direction is equal to the size of the second part in the second direction, and / or the size of the first bump in the third direction is equal to the size of the second part in the third direction, wherein both the second direction and the third direction are set at an angle to the first direction.

[0011] In some possible implementations, the second part has a recess, which is located on opposite sides of the first protrusion. By providing a recess in the second part, the recess can be used to accommodate other structural components within the folding mechanism.

[0012] In some possible implementations, the recess extends to the edge of the second portion in the third-direction direction, wherein the third-direction direction is set at an angle to the first direction. By setting the recess to extend to the edge of the second portion in the third-direction direction, it is advantageous for other mechanical components within the folding mechanism to be installed within the recess.

[0013] In some possible implementations, the first protrusion includes a first top edge, which connects to the first groove and is located on the side of the first protrusion closer to the opening of the first groove; in the third direction, the distance between the first top edge and the opening of the first groove is greater than or equal to 0 and less than or equal to 0.35 mm, wherein the third direction is set at an angle to the first direction.

[0014] By setting the distance range between the first top edge of the first protrusion and the opening of the first groove in the third direction, the distance between the first top edge and the bottom end of the second part (i.e., the rotation center of the shielding member) can be increased, which also increases the torque of the resisting force on the shielding member, thereby effectively reducing the amount of rotation of the shielding member and improving the reliability of the electronic device.

[0015] In some possible implementations, in the third direction, the ratio of the size of the first bump to the size of the second part in the third direction is greater than or equal to 0.05 and less than or equal to 1, and the third direction is set at an angle to the first direction.

[0016] By setting a range for the ratio of the size of the first protrusion in the third direction to the size of the second part in the third direction, the structural strength of the first protrusion is ensured to be sufficient to provide a stop function.

[0017] In some possible implementations, the shielding element includes a first part, and the second part includes a second protrusion located on the same side of the shielding element as the first protrusion, with at least a portion of the second protrusion disposed on the spindle.

[0018] By adding a second protrusion, the contact area between the first part and the spindle can be increased, thereby improving the connection strength between the first part and the spindle. In addition, adding a second protrusion helps to disperse stress concentration in the first part, preventing the first part from breaking or cracking under stress, and improving the structural strength of the shielding component.

[0019] Secondly, this application provides a folding mechanism. The folding mechanism includes a main shaft and a shielding member as described in any of the possible implementations above, the shielding member being mounted on the main shaft.

[0020] In some possible implementations, the spindle has a first groove, and at least part of the first protrusion is located within the first groove.

[0021] By setting the first protrusion to be located within the first groove and between the second part and the first groove, it is beneficial to reduce the gap between the second part and the first groove, reduce the space for the shielding member to move within the first groove, thereby improving the reliability of the connection when the shielding member is installed in the first groove.

[0022] In some possible implementations, a protrusion is provided in the first groove, and at least part of the protrusion extends into the recess of the shielding member.

[0023] When the electronic device falls and the shielding component rotates, the end of the second part can rotate to abut against the protrusion, which can also stop the rotation of the shielding component, thereby reducing the amount of rotation of the shielding component and reducing the possibility of the shielding component hitting the flexible display screen when it falls over.

[0024] Thirdly, this application also provides another folding mechanism. The folding mechanism includes a main shaft, a shielding member, and a first protrusion. The main shaft is provided with a first groove, at least a portion of the shielding member is installed in the first groove, and the first protrusion is fixed to the side of the first groove facing the shielding member.

[0025] Fourthly, this application provides an electronic device including a flexible display screen, a first housing, a second housing, and a folding mechanism as described in any of the above possible embodiments. The folding mechanism connects the first housing and the second housing and is used to enable the first housing and the second housing to be folded or unfolded relative to each other. The first housing, the second housing, and the folding mechanism together support the flexible display screen. Attached Figure Description

[0045] The following embodiments of this application will be described in conjunction with the accompanying drawings.

[0046] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Rotary connection" refers to a connection where the components can rotate relative to each other after connection. The directional terms mentioned in the embodiments of this application, such as "up," "down," "left," "right," "inner," and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0047] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly specifying the number of technical features. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In this context, an integrally formed structural component refers to a component in which one part is connected to another part during the formation of that component, without requiring further processing (such as bonding, welding, snap-fit ​​connections, or screw connections) to join the two parts.

[0048] Furthermore, the mathematical concepts mentioned in the embodiments of this application, such as parallel and perpendicular, are limitations specific to the current technological level, rather than absolute and strict mathematical definitions. Slight deviations are permissible; approximations of parallelism or perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0049] Please refer to the following: Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of an electronic device 1000 in the open state according to an embodiment of this application. Figure 2 yes Figure 1 The diagram shows the structure of the electronic device 1000 when it is in the closed state. Figure 3 yes Figure 2 A partial structural schematic diagram of the electronic device 1000 shown.

[0050] The electronic device 1000 can be a foldable electronic product such as a mobile phone, tablet computer, or laptop computer. This application uses a mobile phone as an example for illustration. Of course, other types of electronic devices 1000 can also adopt a similar structure, which will not be elaborated upon below.

[0051] In some embodiments, the electronic device 1000 may include a flexible display screen 100 and a folding device 200, wherein the flexible display screen 100 is mounted on the folding device 200. For example... Figure 1 As shown, the folding device 200 can be unfolded to an open state; as Figure 2 As shown, the folding device 200 can also be folded to a closed state; the folding device 200 can also be unfolded or folded to an intermediate state, which can be any state between the open and closed states. The flexible display screen 100 moves with the folding device 200, and under the drive of the folding device 200, the flexible display screen 100 can also be unfolded or folded, so that the entire electronic device 1000 can be unfolded to an open state or folded to a closed state.

[0052] The flexible display screen 100 can integrate display and touch sensing functions. The display function of the flexible display screen 100 is used to display text, images, videos, etc., while the touch sensing function is used to detect user touch actions to achieve human-computer interaction. The flexible display screen 100 can be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, a mini organic light-emitting diode (MOLED) display, a micro light-emitting diode (MLED) display, or a quantum dot light-emitting diode (QLED) display.

[0053] In this embodiment, as Figure 1 As shown, the flexible display screen 100 may include a first display area 100a, a third display area 100c, and a second display area 100b arranged sequentially. The folding device 200 may include a first housing 1, a second housing 2, and a folding mechanism 3. The folding mechanism 3 is connected between the first housing 1 and the second housing 2, and is used to enable the first housing 1 and the second housing 2 to be folded or unfolded relative to each other. The first housing 1, the second housing 2, and the folding mechanism 3 together support the flexible display screen 100. Specifically, the portion of the flexible display screen 100 corresponding to the first housing 1 is the first display area 100a, which is fixed to the first housing 1; the portion of the flexible display screen 100 corresponding to the second housing 2 is the second display area 100b, which is fixed to the second housing 2; and the portion of the flexible display screen 100 corresponding to the folding mechanism 3 is the third display area 100c. The movement of the folding mechanism 3 allows the first housing 1 and the second housing 2 to open or close relative to each other. During the process of the first housing 1 and the second housing 2 unfolding or folding relative to each other, the first housing 1 drives the first display area 100a to rotate, the second housing 2 drives the second display area 100b to rotate, and the third display area 100c deforms under the influence of the first display area 100a, the second display area 100b, and the folding device 200. The third display area 100c may be partially fixed to the folding device 200 or not fixed at all; this embodiment does not limit this.

[0054] For example, the first housing 1 may include a first middle frame 11 and a first rear cover 12. The first rear cover 12 is located on one side of the first middle frame 11, and the first display area 100a may be connected to the other side of the first middle frame 11. The first rear cover 12, the first middle frame 11, and the first display area 100a may together form a first accommodating space 13. The first accommodating space 13 may be used to accommodate other structural components within the electronic device 1000, such as batteries and circuit boards. The first rear cover 12 and the first display area 100a may be connected to the first middle frame 11 by adhesive bonding or snap-fitting, or the first middle frame 11 and the first rear cover 12 may be integrally formed structural components; this application does not limit this. The first rear cover 12 may be a glass screen or a battery cover.

[0055] For example, the second housing 2 may include a second middle frame 21 and a second rear cover 22. The second rear cover 22 and the second display area 100b are respectively connected to opposite sides of the second middle frame 21. The second accommodating space 23 is formed by the second rear cover 22, the second middle frame 21 and the second display area 100b, and is used to accommodate other structural components within the electronic device 1000. This application embodiment does not limit the scope of the embodiments. The second rear cover 22 may be a glass screen or a battery cover.

[0056] like Figure 1 As shown, the first housing 1 and the second housing 2 can be opened relative to each other to an open state, so that the folding mechanism 3, the folding device 200, and the electronic device 1000 are all in an open state, and the flexible display screen 100 can unfold along with the folding device 200. For example, when the folding device 200 is in the open state, the first housing 1 can be spliced ​​with the second housing 2, and the included angle between the first housing 1 and the second housing 2 can be approximately 180°. The flexible display screen 100 can be in a flat state, and the first display area 100a, the third display area 100c, and the second display area 100b are all located on the same plane, so that the flexible display screen 100 can perform full-screen display, and the electronic device 1000 can have a larger planar size to improve the user's viewing and operating experience.

[0057] like Figure 2 and Figure 3As shown, the first housing 1 and the second housing 2 can be closed relative to each other to a closed state, so that the folding mechanism 3, the folding device 200, and the electronic device 1000 are all in a closed state, and the flexible display screen 100 can fold along with the folding device 200. When the folding device 200 is in the closed state, the first housing 1 and the second housing 2 can partially or completely abut against each other, and the included angle between the first housing 1 and the second housing 2 can be approximately 0°. In this embodiment, when the folding device 200 is in the closed state, the flexible display screen 100 can be relatively closed and located between the first housing 1 and the second housing 2. The first display area 100a and the second display area 100b are arranged face to face, and the third display area 100c is deformed into a bent shape, so that the third display area 100c can be approximately "teardrop-shaped". In other embodiments, the third display area 100c can also be "U-shaped", "baseball-shaped", or other shapes, which are not limited in this application.

[0058] When the folding device 200 is in the closed state, so that the electronic device 1000 is in the closed state, the electronic device 1000 can have a small planar size, making it easy for users to hold, carry, and store. Among these, in Figure 2 In the illustrated embodiment, when the folding device 200 is in the closed state, the flexible display screen 100 can be located inside the folding device 200, enclosed by the first housing 1 and the second housing 2 of the folding device 200. In some other embodiments, when the folding device 200 is in the closed state, the flexible display screen 100 can be located outside the folding device 200, exposed relative to the first housing 1 and the second housing 2. This embodiment of the present application does not limit this.

[0059] In some embodiments, the first housing 1 and the second housing 2 may be opened or closed relative to each other to an intermediate state, so that the folding mechanism 3, the folding device 200 and the electronic device 1000 are all in an intermediate state, and the flexible display screen 100 will also deform according to the state of the folding device 200 to meet the user's viewing needs from different angles.

[0060] For ease of description, exemplarily, the definitions are as follows: Figure 1 The length direction of the electronic device 1000 shown is the first direction, such as the X direction; the width direction of the electronic device 1000 is the second direction, such as the Y direction; and the height direction of the electronic device 1000 is the third direction, such as the Z direction. Any two of the first, second, and third directions are perpendicular to each other. In some other embodiments, the coordinate system of the electronic device 1000 can also be flexibly set according to specific needs, and this application embodiment does not limit this.

[0061] In this embodiment, such as Figure 1 and Figure 2As shown, the direction of the relative rotation axis of the first housing 1 and the second housing 2 can be parallel to the first direction, that is, the folding mechanism 3 and the folding device 200 can be relatively flattened or folded along the rotation axis parallel to the first direction, wherein the first direction can be the length direction of the electronic device 1000. Thus, when the electronic device 1000 is in a closed state, the size of the electronic device 1000 in the second direction becomes smaller, making it easier for the user to carry, wherein the second direction can be the width direction of the electronic device 1000. In other words, the electronic device 1000 can be folded left and right, and the folding and flattening of the electronic device 1000 affects its width. This embodiment is illustrated using the example of "the direction of the rotation axis of the electronic device 1000 being parallel to the first direction." In other embodiments, the rotation axis of the electronic device 1000 can also be parallel to the second direction, and the electronic device 1000 can be folded up and down, with the folding and flattening affecting its length. This application embodiment does not limit this.

[0062] It should be noted that, Figure 1 , Figure 2 , Figure 3 The accompanying drawings below only schematically illustrate some components included in the electronic device 1000; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 , Figure 2 , Figure 3 As well as the limitations of the accompanying figures below.

[0063] For example, the electronic device 1000 may further include multiple components (not shown in the figure), which are housed within the first accommodating space 13 and / or the second accommodating space 23. These multiple components may include, but are not limited to, a processor, an internal processor, an external storage interface, a universal serial bus (USB) interface, a charging management module, a power management module, an antenna, a communication module, an audio module, a speaker, a receiver, a microphone, a headphone jack, a sensor module, and a subscriber identification module (SIM) card interface. The electronic device 1000 may have more or fewer components than described above, may combine two or more components, or may have different component configurations. This application does not specifically limit the number, type, or location of the modules within the electronic device 1000.

[0064] It is understood that in this embodiment, the electronic device 1000 is described as having a two-fold structure, that is, the electronic device 1000 includes two shells that can be bent relative to each other. In some other embodiments, the electronic device 1000 may also have a three-fold or more-fold structure, that is, the electronic device 1000 may include three or more shells that are bent relative to each other, and any two adjacent shells are connected by a folding mechanism 3. When the electronic device 1000 has a three-fold or more-fold structure, the structure of the electronic device 1000 can be adapted by referring to the description of the two structures in this embodiment, and this application will not repeat it here.

[0065] The following is an example illustrating the implementation structure of the folding mechanism 3.

[0066] Please refer to the following: Figure 1 and Figure 4 , Figure 4 yes Figure 1 The diagram shows the structure of the spindle assembly 31.

[0067] In some embodiments, the folding mechanism 3 may include a main shaft assembly 31 and connecting components (not shown in the figures). The connecting components may all be connected to the main shaft assembly 31 and can be unfolded or folded relative to the main shaft assembly 31. The connecting components are also connected between the first housing 1 and the second housing 2. By moving the connecting components relative to the main shaft assembly 31, the first housing 1 and the second housing 2 can move relative to the main shaft assembly 31, thus achieving relative movement between the first housing 1 and the second housing 2. Multiple connecting components can be arranged at intervals along the length extension direction of the main shaft 32. The coordinated movement of multiple connecting components makes the movement of the first housing 1 and the second housing 2 during relative unfolding or folding more stable and reliable. In this embodiment, the length extension direction of the main shaft assembly 31 may be parallel to a first direction; that is, the connecting components can cause the first housing 1 and the second housing 2 to be relatively flattened or folded along a rotation axis parallel to the first direction. In this case, the first housing 1 and the second housing 2 are located on opposite sides of the main shaft 32 in the second direction.

[0068] Please see Figure 5 and Figure 6 , Figure 5 yes Figure 4 The diagram shows an exploded view of the spindle assembly 31 in some embodiments. Figure 6 yes Figure 5 The exploded view of the spindle assembly 31 shown from another perspective.

[0069] The spindle assembly 31 may include a spindle 32. The spindle 32 may be a continuous structural component, generally elongated, and its length extension direction corresponds to the length extension direction of the spindle assembly 31. In this embodiment, the length extension direction of the spindle 32 may be parallel to a first direction. The spindle 32 may also have a width direction and a height direction; the width direction of the spindle 32 may be perpendicular to its length extension direction, and the height direction may be perpendicular to both its length extension direction and its width direction. In this embodiment, the width direction of the spindle 32 may be parallel to a second direction, and the thickness direction of the spindle 32 may be parallel to a third direction. For example... Figure 5 As shown, the spindle 32 may include a support part 32a and a rear shell 32b. The support part 32a can be used to install structural components such as connecting parts, and the rear shell 32b can be used to decorate the appearance of the support part 32a.

[0070] Please refer to the reference again. Figure 3 and Figure 4 In some embodiments, the spindle assembly 31 may further include two first components 33, which may be respectively mounted on opposite ends of the spindle 32 in a first direction. The first components 33 can protect the edges of the flexible display screen 100, preventing the edges of the flexible display screen 100 from being exposed. On the one hand, this can improve the appearance of the electronic device 1000, and on the other hand, it can prevent the edges of the flexible display screen 100 from being damaged by collisions. It can also prevent water, dust and other external impurities from penetrating into the electronic device 1000 through the edges of the flexible display screen 100, thus affecting the service life of the internal structural components of the electronic device 1000.

[0071] Please see Figure 5 , Figure 7 and Figure 8 , Figure 7 yes Figure 5 The diagram shows the cross-sectional structure of the main shaft 32 at point AA. Figure 8 yes Figure 5 The diagram shows the cross-sectional structure of the main shaft 32 at BB.

[0072] The spindle 32 may include a first surface 321 and a second surface 322 disposed opposite to each other in a third direction, wherein the first surface 321 is oriented towards the flexible display screen 100 (e.g., ...). Figure 3The second surface 322 is the surface of the main shaft 32 facing away from the flexible display screen 100. The height direction (i.e., the third direction) of the main shaft 32 can be perpendicular to the first surface 321. At least a portion of the first surface 321 can be a support surface of the main shaft 32 for the flexible display screen 100. The first surface 321 can be a plane, a curved surface, or a surface formed by connecting multiple planes and curved surfaces, used to realize the third display area 100c of the electronic device 1000 in different states (e.g., ...). Figure 3 The support shown is not limited in this application. It is understood that the first surface 321 and the second surface 322 can be opposite sides of the same component within the spindle 32, or they can be formed on different components within the spindle 32. The embodiments of this application do not limit this.

[0073] For example, the spindle 32 may include a main body 323 and two bosses 324, which may be fixed to opposite ends of the main body 323 in a first direction. That is, opposite ends of the spindle 32 in the first direction may be formed by two bosses 324, and the spindle 32 may be approximately a long strip structure with protruding ends. The bosses 324 and the main body 323 may be integrally formed, or they may be formed into an integral structure by means of adhesive bonding, welding, etc. The embodiments of this application do not limit this.

[0074] In some embodiments, the boss 324 may protrude relative to the body portion 323 toward the side opposite to the second surface 322.

[0075] Combination Figure 3 and Figure 5As shown in the figure, in the embodiment of the present application, the flexible display screen 100 can be disposed between two bosses 324. The surface of the main body portion 323 facing the flexible display screen 100 can be the supporting surface of the main shaft 32 for the flexible display screen 100. Specifically, the first surface 321 can include a first sub-surface 3211 and a second sub-surface 3212. The first sub-surface 3211 can be formed on the side of the boss 324 away from the second surface 322, and the second sub-surface 3212 can be formed on the side of the main body portion 323 away from the second surface 322. The projection of the flexible display screen 100 in the plane of the second sub-surface 3212 can overlap with the second sub-surface 3212, and the projection of the flexible display screen 100 in the plane of the first sub-surface 3211 is located outside the first sub-surface 3211. That is to say, the flexible display screen 100 is disposed corresponding to the main body portion 323, and the surface of the main body portion 323 facing the flexible display screen 100 (that is, the second sub-surface 3212) is used to support the flexible display screen 100. In other words, in the embodiment of the present application, part of the first surface 321 is the supporting surface of the main shaft 32 for the flexible display screen 100. In some other embodiments, the main shaft 32 may not include two bosses 324, and the entire first surface 321 may be the supporting surface of the main shaft 32 for the flexible display screen 100. The embodiment of the present application does not limit this.

[0076] In addition, as Figure 3 and Figure 5 shown, the boss 324 protrudes from the main body portion 323 toward the side away from the second surface 322. It can be understood that in the third direction, the first sub-surface 3211 can be closer to the flexible display screen 100 than the second sub-surface 3212. It can be understood that the second surface 322 can be various shapes such as a plane or a concave curved surface. That is to say, the maximum dimension of the boss 324 in the third direction can be greater than, less than or equal to the maximum dimension of the main body portion 323 in the third direction. The embodiment of the present application does not limit this.

[0077] As Figure 6 shown, in some examples, the boss 324 can include a first convex portion 3241, a second convex portion 3242 and a third convex portion 3243 connected in sequence along the second direction. The second convex portion 3242 can protrude from the first convex portion 3241 and the third convex portion 3243 toward the side away from the second surface 322. As Figure 6 shown, in the embodiment of the present application, the boss 324 can be approximately in a "convex" shape. The dimension of the first convex portion 3241 in the third direction can be equal to the dimension of the third convex portion 3243 in the third direction, and the dimension of the second convex portion 3242 in the third direction can be greater than the dimension of the first convex portion 3241 in the third direction. The embodiment of the present application does not limit the specific dimension relationship of the first convex portion 3241, the second convex portion 3242 and the third convex portion 3243.

[0078] Please refer to it again. Figure 7 and Figure 8 In some embodiments, the spindle 32 may be provided with a first groove 325, which may be disposed at the end of the spindle 32 (i.e., within the boss 324). The first groove 325 may be formed by at least a portion of the first sub-surface 3211 recessed toward the second surface 322. Exemplarily, the first groove 325 may include an opening 3251, a first bottom wall 3252, a first side wall 3253, and a second side wall 3254. The opening 3251 is used to connect the first groove 325 with the external space. The first side wall 3253 and the second side wall 3254 are at least partially opposite each other in a first direction. The second side wall 3254 is disposed closer to the edge of the spindle 32 than the first side wall 3253, and the first bottom wall 3252 is connected between the first side wall 3253 and the second side wall 3254.

[0079] In this embodiment, the first sidewall 3253 may be parallel to a portion of the second sidewall 3254, or the first sidewall 3253 may be at an obtuse angle to a portion of the second sidewall 3254. In other embodiments, the first sidewall 3253 may be parallel to all of the second sidewalls 3254, or the first sidewall 3253 may be at an angle to all of the second sidewalls 3254; this embodiment does not limit this. The first sidewall 3253 may include a first edge 32531 in a third direction, and the first edge 32531 is connected to the opening 3251.

[0080] For example, the spindle 32 may include a protrusion 326, which may be disposed within the first groove 325 and protrude toward the opening 3251 relative to the first bottom wall 3252. In some examples, the protrusion 326 may be located within the space formed between the first bottom wall 3252 and the second side wall 3254. The protrusion 326 may be integrally formed with the boss 324, or the protrusion 326 may be connected to the first bottom wall 3252 or the second side wall 3254 by means of adhesive bonding, welding, etc., to form an integral structure. This application embodiment does not limit this.

[0081] In some examples, the protrusion 326 may include a third surface 3261 and a fourth surface 3262 arranged at an angle. The extension direction of the third surface 3261 may be parallel to a third direction, and the extension direction of the fourth surface 3262 may be parallel to a first direction. The third surface 3261 may be spaced apart from the first sidewall 3253. The angle between the third surface 3261 and the fourth surface 3262 may be a right angle, an acute angle, or an obtuse angle, etc., and the connection between the first surface 321 and the second surface 322 may also be a rounded corner. This application embodiment does not limit this. In other embodiments, the extension direction of the third surface 3261 may be arranged at an angle to a third direction, and the extension direction of the fourth surface 3262 may be arranged at an angle to the first direction. This application embodiment does not limit this either.

[0082] For example, the number of protrusions 326 in the first groove 325 can be two, and the two protrusions 326 can be spaced apart along the second direction. For example, along the first direction, the projections of the two protrusions 326 can overlap with the first protrusion 3241 and the third protrusion 3243, respectively. In some other embodiments, the number of protrusions 326 can also be one, three or more, and the projections of the protrusions 326 along the first direction can also correspond to the second protrusion 3242. Alternatively, the protrusions 326 can also be approximately elongated, connecting the two opposite sides of the groove wall of the first groove 325 in the second direction, and corresponding to the first protrusion 3241, the second protrusion 3242 and the third protrusion 3243. The embodiments of this application do not limit this. It is understood that in this application embodiment, the protrusion 326, the first groove 325 and the boss 324 at one end of the spindle 32 are described as examples. The number, position and connection relationship of the protrusion 326, the first groove 325 and the boss 324 at the other end of the spindle 32 can be adapted with reference to the relevant content, and this application will not repeat them.

[0083] Please refer to the following: Figure 4 , Figure 9 and Figure 10 , Figure 9 yes Figure 5 The exploded structural diagram of the first component 33 is shown. Figure 10 yes Figure 9 The shielding element 331 shown is a structural schematic diagram from another perspective.

[0084] In some embodiments, the first component 33 may include a shielding member 331, a second structural member 332 and a third structural member 333, with the shielding member 331 mounted on the spindle 32 and the second structural member 332 connected between the shielding member 331 and the third structural member 333, so that the first component 33 is mounted on the spindle 32.

[0085] For example, the shielding member 331 may include a first part 3311, a third part 3312, and a second part 3313 connected sequentially in the second direction. The maximum dimension of the first part 3311 in the second direction may be greater than the maximum dimension of the third part 3312 in the second direction, and the minimum dimension of the third part 3312 in the second direction may be equal to the maximum dimension of the second part 3313 in the second direction. The first part 3311, the third part 3312, and the second part 3313 may be an integrally formed structure, or they may be formed into an integral structure by means of adhesive bonding, welding, etc. This application embodiment does not limit this. The maximum dimension of the third part 3312 in the second direction may be equal to or greater than the minimum dimension of the third part 3312 in the second direction; this application embodiment does not limit this.

[0086] For example, the first part 3311 may include a fixed block 33111 and a second protrusion 33112 that are fixedly connected. The fixed block 33111 may be provided with a second groove 33113. One end of the second groove 33113 facing the third part 3312 may communicate with the external space of the second groove 33113. In a first direction, the second protrusion 33112 protrudes relative to the fixed block 33111 in a direction away from the fixed block 33111. In a third direction, the second protrusion 33112 may be disposed at the end of the fixed block 33111 closer to the third part 3312. The number of second protrusions 33112 may be two, and the two second protrusions 33112 may be spaced apart along the second direction. The embodiments of this application do not limit the shape, number, etc. of the second protrusions 33112. The fixing block 33111 and the second protrusion 33112 can be integrally formed, or the fixing block 33111 and the second protrusion 33112 can also be formed into an integral structure by means of adhesive bonding, welding or other methods. This application embodiment does not limit this.

[0087] For example, the third part 3312 may be provided with an installation space 3314, which may be located on the same side of the shield 331 as the second protrusion 33112 (denoted as the first side 331a of the shield 331 for distinction), and in the second direction, the installation space 3314 may be located between the two second protrusions 33112.

[0088] For example, the second part 3313 may have a second notch 33131. The second notch 33131 can be used to accommodate connecting materials such as glue or solder for connecting the shielding member 331 to other structural members when the shielding member 331 is installed on other structural members. The second notch 33131 may be located on the first side 331a of the shielding member 331, and / or the second notch 33131 may also be located on the second side 331b of the shielding member 331, where the second side 331b and the first side 331a are opposite sides of the shielding member 331 in a first direction. Furthermore, a first protrusion 3313a may be provided within the second notch 33131 to increase the reliability of the connection when the shielding member 331 is installed on other structural members. The number of second notches 33131 may be one, two, three, or more; this embodiment does not limit this.

[0089] For example, the second portion 3313 may also be provided with a first protrusion 3315. The first protrusion 3315 may be located on the first side 331a of the shielding member 331, and the first protrusion 3315 may extend in a direction away from the second side 331b. Along the first direction, the projection of the first protrusion 3315 overlaps with at least a portion of the second portion 3313. The direction in which the first protrusion 3315 points towards the second portion 3313 may be parallel to the first direction; in other words, the first protrusion 3315 is fixed to the surface of the second portion 3313 facing the first side 331a in the first direction. The number of first protrusions 3315 may be one, two, three, or more, and this embodiment does not limit this. When there are multiple first protrusions 3315, the multiple first protrusions 3315 may be arranged at intervals along the second direction, for example, as shown in the example below. Figure 9 As shown, there can be two first protrusions 3315. Along the second direction, the two first protrusions 3315 can be at least partially opposite each other and spaced apart along the second direction. The two first protrusions 3315 can be respectively close to the opposite ends of the second part 3313 in the second direction. In some other embodiments, the first protrusions 3315 can also be approximately elongated, connecting the opposite ends of the second part 3313 in the second direction. The embodiments of this application do not limit the size, shape, number, and position of the first protrusions 3315.

[0090] In some examples, the first protrusion 3315 may be disposed at the end of the second portion 3313 away from the first portion 3311. The first protrusion 3315 may include a fifth surface 33151. In a first direction, the fifth surface 33151 may be located on the side of the first protrusion 3315 away from the fixing block 33111. In a third direction, the fifth surface 33151 may include a first top edge 3315a and a first bottom edge 3315b, with the first top edge 3315a being closer to the first portion 3311 than the first bottom edge 3315b. The fifth surface 33151 may be a plane, a curved surface, or an inclined surface, and this embodiment of the application does not limit this.

[0091] For example, the second part 3313 may also be provided with a recess 33132 (such as...). Figure 10 As shown), the recess 33132 can be located on the second side 331b of the shielding member 331, that is, the recess 33132 can be located on the opposite sides of the first protrusion 3315 in the second part 3313. The recess 33132 can be formed by a portion of the second part 3313 recessed inward, and the recess 33132 can extend to the side of the second part 3313 away from the first part 3311 (that is, the edge of the second part 3313 in the third direction). The number of recesses 33132 can be one, two, three or more, and this embodiment does not limit this. When there are multiple recesses 33132, the multiple recesses 33132 can be arranged along the second direction, for example, as shown in... Figure 10 As shown, there can be two recesses 33132. The two recesses 33132 can be arranged at intervals near the opposite ends of the shielding member 331 in the second direction, and the recesses 33132 can also connect to the external space of the shielding member 331 in the second direction. In some other embodiments, the recesses 33132 can also be approximately elongated, and the recesses 33132 can penetrate through the opposite sides of the second part 3313 in the second direction. The embodiments of this application do not limit the size, shape, number, and position of the recesses 33132.

[0092] For example, the second structural member 332 can be disposed in the installation space 3314, and the third structural member 333 and the second structural member 332 can be located on the same side of the shielding member 331. The second structural member 332 may have a first notch 3321 at its third-direction end. For instance, when the second structural member 332 is fixed in the installation space 3314 by welding, the stress at the connection between the second structural member 332 and the shielding member 331 is relatively high, which can easily lead to welding cracks. By providing the first notch 3321, the stress concentration point can be dispersed, improving the reliability of the welding process, and also making it easier for the welding torch or welding rod to reach the welding position, reducing the difficulty of welding. The third structural member 333 can be connected to the second structural member 332 by means of insert injection molding, adhesive bonding, snap-fit, screws, etc., which is not limited in this embodiment.

[0093] Please refer to it again. Figure 1 , Figure 3 and Figure 4 For example, the shielding member 331 can be made of sintered metal, the second structural member 332 can be made of materials such as steel sheets or iron sheets, and the third structural member 333 can be made of flexible materials such as rubber. When the first component 33 is mounted on the spindle 32, the shielding member 331 is closer to the boss 324 than the third structural member 333. The flexible display screen 100 can be located on the side of the third structural member 333 facing away from the second surface 322. The two ends of the third structural member 333 in the second direction can be respectively disposed in the first housing 1 and the second housing 2. When the first housing 1 and the second housing 2 are relatively unfolded or relatively folded, the third structural member 333 can also be relatively unfolded or relatively folded. The structural strength of the shielding member 331 and the second structural member 332 is greater than that of the third structural member 333, which can provide effective support for the third structural member 333. In some other embodiments, the third structural member 333 may also be embedded with components such as steel sheets to increase the structural strength of the third structural member. This application does not limit this.

[0094] Please see Figure 11 and Figure 12 , Figure 11 yes Figure 4 The diagram shows the structure of the main shaft 32 and the shielding member 331. Figure 12 yes Figure 4 The schematic diagram of the main shaft 32 and the shielding member 331 from another perspective.

[0095] When the shielding member 331 is mounted on the spindle 32, the first side 331a of the shielding member 331 can be closer to the flexible display screen 100 relative to the second side 331b of the shielding member 331 (e.g., Figure 3 (As shown in the image) settings.

[0096] In some embodiments, at least a portion of the first part 3311 may be disposed on the boss 324 of the spindle 32. The at least portion of the first part 3311 may be contacted or connected to the first sub-surface 3211 of the boss 324 by means of adhesive or welding. The boss 324 may provide support for the first part 3311, i.e., the shielding member 331.

[0097] Please see Figure 13 , Figure 13 yes Figure 11 The diagram shows a cross-sectional view of the spindle 32 and the shielding member 331 at CC. For example, the second protrusion 3242 can be embedded within the recess 33132. By providing the recess 33132, the reliability of the connection between the shielding member 331 and the first part 3311 (i.e., the shielding member 331) can be improved, and the weight of the shielding member 331 can be reduced, thus lowering the manufacturing cost of the shielding member 331.

[0098] Please refer to the following: Figure 12 and Figure 14 , Figure 14 yes Figure 11 The diagram shows a cross-sectional view of the spindle 32 and the shielding member 331 at point DD. For example, at least a portion of the second protrusion 33112 can be disposed on the side of the boss 324 facing away from the second surface 322 (i.e., the first sub-surface 3211). The second protrusion 33112 can contact the boss 324, or it can be connected to the boss 324 by adhesive, welding, or other means. By providing the second protrusion 33112, the contact area between the first portion 3311 and the spindle 32 can be increased, thereby improving the connection strength between the first portion 3311 and the spindle 32. Furthermore, providing the second protrusion 33112 helps to disperse stress concentration in the first portion 3311, preventing breakage or cracks in the first portion 3311 under stress, and improving the structural strength of the shielding member 331.

[0099] Please see Figure 15 , Figure 15 yes Figure 11 The diagram shows the cross-sectional structure of the main shaft 32 and the shielding member 331 at EE.

[0100] In some embodiments, at least a portion of the shielding member 331 is installed in the first groove 325, and at least a portion of the second portion 3313 can be disposed within the first groove 325 of the spindle 32. The first protrusion 3315 can be located on the side of the shielding member 331 near the first sidewall 3253. For example, the fifth surface 33151 can be located on the side of the first protrusion 3315 near the first sidewall 3253. By disposing at least a portion of the second portion 3313 within the first groove 325 of the spindle 32, the first groove 325 can provide positioning and limiting for the installation process of the shielding member 331, and also increases the contact area between the shielding member 331 and the spindle 32, which is beneficial to improving the reliability of the shielding member 331 when installed on the spindle 32. The second portion 3313 can be connected to the first groove 325 by contact or by adhesive or welding. In this embodiment, the second portion 3313 is described as being bonded to the first groove 325 by adhesive.

[0101] Please see Figure 16 , Figure 16 This is a partial structural diagram of an electronic device 1000 provided by existing technology. It is understood that when the electronic device 1000 is dropped, the flexible display screen 100 will continue to move towards the shielding member 331 due to inertia. After the shielding member 331 is subjected to external impact force, the adhesive between the shielding member 331 and the first sidewall 3253 will be squeezed and deformed. The shielding member 331 will rotate towards the flexible display screen 100 with the second part 3313 as the rotation center, which may cause the flexible display screen 100 to collide with the shielding member 331 and be damaged, affecting the reliability of the electronic device 1000.

[0102] In the embodiments of this application, such as Figure 15 As shown, by setting the first protrusion 3315, the gap between the first sidewall 3253 and the second part 3313 can be reduced. When the electronic device 1000 falls, the first protrusion 3315 can abut against the first sidewall 3253 of the first groove 325 and stop with the first groove 325 to limit the rotation of the shielding member 331, thereby reducing the amount of rotation of the shielding member 331, reducing the possibility of the shielding member 331 hitting the flexible display screen 100 when it falls, and improving the reliability of the electronic device 1000.

[0103] Combination Figure 7 and Figure 15As shown, in some examples, the distance between the first top edge 3315a of the first protrusion 3315 and the opening 3251 of the first groove 325 in the third direction can be greater than or equal to 0 and less than or equal to 0.35 mm. For example, the distance between the first top edge 3315a of the first protrusion 3315 and the opening 3251 of the first groove 325 in the third direction can be 0, 0.1 mm, 0.2 mm, or 0.35 mm, etc. It is understood that when the distance between the first top edge 3315a of the first protrusion 3315 and the opening 3251 of the first groove 325 in the third direction is 0, it can be considered that the first top edge 3315a is flush with the first edge 32531 of the first sidewall 3253 (the first sidewall 3253 is connected to the edge of the opening 3251). By setting the distance range between the first top edge 3315a of the first protrusion 3315 and the opening 3251 (i.e., the first edge 32531) of the first groove 325 in the third direction, the distance between the first top edge 3315a and the bottom end of the second part 3313 (i.e., the rotation center of the shielding member 331) can be increased, and the torque of the resisting force on the shielding member 331 can also be increased, thereby effectively reducing the rotation amount of the shielding member 331 and improving the reliability of the electronic device 1000. Figure 15 In the illustrated embodiment, the first top edge 3315a is located within the first groove 325, and the first top edge 3315a is closer to the second surface 322 relative to the first edge 32531. In other embodiments, the first top edge 3315a may be further away from the second surface 322 relative to the first edge 32531, and this application embodiment does not limit this.

[0104] In some embodiments, in a first direction, the projection of the first protrusion 3315 and the second portion 3313 at least partially overlap.

[0105] In some implementations, the ratio of the dimension of the first protrusion 3315 in the third-party direction to the dimension of the second portion 3313 in the third-party direction can be greater than or equal to 0.05 and less than or equal to 1. It is understood that the dimension of the first protrusion 3315 in the third-party direction can be the distance between the first top edge 3315a and the first bottom edge 3315b in the third-party direction, and the dimension of the second portion 3313 in the third-party direction can be the distance between the edges of the first top edge 3315a and the edges of the second portion 3313 furthest from the first top edge 3315a in the third-party direction. For example, the ratio of the dimension of the first protrusion 3315 in the third-party direction to the dimension of the second portion 3313 in the third-party direction can be 0.05, 0.2, 0.4, 0.6, 0.9, or 1. By setting the range of the ratio of the dimension of the first protrusion 3315 in the third-party direction to the dimension of the second portion 3313 in the third-party direction, the structural strength of the first protrusion 3315 is ensured to be sufficient to provide a stopping function.

[0106] For example, the dimension of the first protrusion 3315 in the first direction can be greater than or equal to 0.01 mm. The dimension of the first protrusion 3315 in the first direction can be the distance in the first direction between the fifth surface 33151 and the connection between the first protrusion 3315 and the second part 3313.

[0107] It is understood that the fifth surface 33151 of the first protrusion 3315 and the first sidewall 3253 of the first groove 325 can be spaced apart, or the first protrusion 3315 can also contact the first sidewall 3253. This application embodiment does not limit this. In some other embodiments, the first protrusion 3315 can also be disposed on the main shaft 32. For example, the first protrusion 3315 can be fixed on the first sidewall 3253. This application embodiment does not limit this.

[0108] In some embodiments, at least a portion of the protrusion 326 can extend into the recess 33132 of the second portion 3313. When the electronic device 1000 falls and the shielding member 331 rotates, the end of the second portion 3313 can rotate to abut against the third surface 3261 of the protrusion 326, which can also stop the rotation of the shielding member 331, thereby reducing the amount of rotation of the shielding member 331 and reducing the possibility of the shielding member 331 hitting the flexible display screen 100 when it falls over.

[0109] like Figure 15 In the illustrated embodiment, the fifth surface 33151 of the first protrusion 3315 and the first sidewall 3253 of the first groove 325 are spaced apart, as an example. In other embodiments, the first protrusion 3315 and the first groove 325 may have other relative positional relationships. For example:

[0110] Please see Figure 17 , Figure 17 yes Figure 4 The diagram shows the structure of the spindle 32 and the shielding member 331 in some other embodiments. This embodiment can include most of the technical solutions of the previous embodiments. The following mainly describes the differences between the two, and the majority of the same content will not be repeated.

[0111] For example, the fifth surface 33151 of the first protrusion 3315 can contact the first sidewall 3253 of the first groove 325, effectively reducing the gap between the fifth surface 33151 and the first sidewall 3253, which helps to reduce the rotation of the shielding member 331, thereby reducing the impact of the shielding member 331 on the flexible display screen 100 when it falls over (e.g., Figure 3 (as shown) is a possibility.

[0112] like Figure 9In the illustrated embodiment, two first protrusions 3315 are used, and the two first protrusions 3315 are spaced apart along the second direction. In other embodiments, the first protrusions 3315 may have other design options. For example:

[0113] Please see Figure 18 , Figure 18 yes Figure 4 The diagram shows the structure of the shielding member 331 in some other embodiments. This embodiment may include most of the technical solutions of the preceding embodiments. The following mainly describes the differences between the two, while the majority of the same content will not be repeated.

[0114] For example, the first protrusion 3315 can also be approximately elongated, connecting the two opposite ends of the second portion 3313 in the second direction. Correspondingly, the first groove 325 (as shown) Figure 8 The dimensions in the second direction (as shown) can also be adapted. By setting the first protrusion 3315 to be approximately elongated and connecting the two opposite ends of the second part 3313 in the second direction, the area of ​​the surface of the first protrusion 3315 facing the first sidewall 3253 (i.e., the fifth surface 33151) is increased. This is beneficial to increasing the contact area when the first protrusion 3315 abuts against the first sidewall 3253, and to increasing the contact force on the shielding member 331. This effectively reduces the rotation of the shielding member 331 and reduces the impact of the shielding member 331 on the flexible display screen 100 when it falls over (e.g., as shown). Figure 3 This improves the reliability of the electronic device 1000 by providing the possibility of [something shown]. In some other embodiments, the first protrusion 3315 may also be approximately elongated and connect the two opposite ends of the second portion 3313 in the third direction; this embodiment is not limited to this. In this case, the dimension of the first protrusion 3315 in the second direction is equal to the dimension of the second portion 3313 in the second direction. In some other embodiments, the dimension of the first protrusion 3315 in the third direction may also be equal to the dimension of the second portion 3313 in the third direction.

[0115] In the preceding embodiments, the example of the first protrusion 3315 being disposed on the shielding member 331 is described below. Figure 19 As shown, Figure 19 This is a partial structural schematic diagram of another spindle assembly 31 provided in an embodiment of this application.

[0116] For example, the first protrusion 3315 can also be disposed on the side of the first sidewall 3253 facing the shielding member 331. The first protrusion 3315 can be integrally formed with the boss 324, or the first protrusion 3315 can be connected to the first sidewall 3253 by adhesive bonding, welding, or other methods to form an integral structure; this embodiment does not limit this. By fixing the first protrusion 3315 to the first sidewall 3253, the weight of the shielding member 331 can be reduced, making it easier to install the shielding member 331 into the first groove 325.
