Description

Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to a support member and a foldable electronic device. Background Technology

[0002] Foldable electronic devices feature a foldable screen, which includes a folding area and two non-folding areas. The folding area connects the two non-folding areas and can be bent and deformed, allowing the foldable screen to have folded and flattened states. The foldable screen is connected to a hinge, which enables the foldable screen to switch between folded and flattened states.

[0003] To protect the foldable area of ​​the foldable screen, support members are provided on both sides of the foldable screen along the axis of rotation. The steel sheet in the support member is located on the side of the foldable area facing away from the axis of rotation. The soft rubber in the support member is connected to the steel sheet and presses against the side of the foldable area facing away from the axis of rotation. The soft rubber can bend and deform with the foldable area.

[0004] In existing foldable electronic devices, the connection between the steel sheet and the soft rubber is not secure. Utility Model Content

[0005] This application provides a support member and a foldable electronic device, which helps to improve the connection stability between the soft adhesive and the connector.

[0006] In a first aspect, this application provides a foldable electronic device, which includes a foldable screen, a hinge, and a support member. The foldable screen includes a folded area and two non-folded areas. The foldable screen can have a folded state and a flattened state by bending and deforming the folded area. The hinge is connected to the foldable screen. The support member is used to cover the edge of the folded area on one side in a first direction, which is the same as the axis of the hinge. The support member includes a support block, a connector, and a soft adhesive. The connector is connected to the support block, which is located on one side of the folded area in the first direction. The side of the connector away from the support block has a protrusion extending along the first direction. The protrusion has a first end and a second end arranged opposite to each other in a second direction. The first end has a first groove, which can increase the surface area of ​​the first end. The soft adhesive is connected to the first end, which can increase the connection area between the soft adhesive and the first end. At least a portion of the soft adhesive is disposed in the first groove and connected to the groove wall of the first groove. The first groove is located between the two ends of the protrusion in the first direction. The soft adhesive is in contact with the surface of the foldable screen away from the hinge. The first direction and the second direction intersect.

[0007] In this solution, since the first end is provided with a first groove, when the first end is connected to the soft rubber, the presence of the first groove can increase the connection area between the first end and the soft rubber, thereby improving the connection stability between the soft rubber and the first end, further improving the connection stability between the soft rubber and the protrusion, so that the soft rubber and the connector can achieve a stable connection.

[0008] In conjunction with the first aspect, in one possible implementation, in the third direction, the dimension of the end of the protrusion furthest from the support block is between 0.25mm and 3mm, and the third direction is perpendicular to the first direction. Since the first end has a first groove, the connection area between the protrusion and the soft rubber can be increased. Eliminating the through hole on the protrusion also ensures the stability of the protrusion and the soft rubber meets requirements. Eliminating the through hole on the protrusion allows the first and second ends to be closer together. The dimension of the end of the protrusion furthest from the support block in the third direction can be between 0.25mm and 3mm, thereby reducing the maximum dimension of the protrusion in the third direction. This further reduces the dimension of the area where the soft rubber connects to the protrusion in the third direction. When the soft rubber deforms with the folding area, the deformable area of ​​the soft rubber increases, increasing the bending radius of the soft rubber during deformation, thus improving the situation where the deformable area of ​​the soft rubber is prone to fatigue.

[0009] In conjunction with the first aspect, in one possible implementation, the second end is provided with a second groove, and the soft rubber is connected to the second end. A portion of the soft rubber is disposed in the second groove and connected to the groove wall surface of the second groove. The second groove is located between the two ends of the protrusion in the first direction. The soft rubber portion can be disposed in the second groove, and the soft rubber can connect to the groove wall surface of the second groove to increase the connection area between the soft rubber and the second end, thereby improving the connection stability between the soft rubber and the second end, and further improving the connection stability between the soft rubber and the protrusion, enabling a stable connection between the soft rubber and the connector.

[0010] In conjunction with the first aspect, one possible implementation involves symmetrically arranging the first and second ends. This results in a more balanced force distribution when the protrusion connects to the soft adhesive, leading to better connection stability.

[0011] In conjunction with the first aspect, in one possible implementation, the soft rubber wrapping around at least a portion of the first and second ends can increase the connection area between the soft rubber and the protrusion, thereby improving the connection stability between the soft rubber and the protrusion.

[0012] In conjunction with the first aspect, in one possible implementation, the protrusion is provided with a through hole located between a first end and a second end, and at least a portion of the soft adhesive is disposed within the through hole. The soft adhesive, being disposed within the through hole, can connect with the inner wall of the through hole. While the protrusion has a through hole, by providing a first groove at the first end of the protrusion, the connection area between the soft adhesive and the protrusion can be further increased, thereby further improving the connection stability between the protrusion and the soft adhesive.

[0013] In conjunction with the first aspect, in one possible implementation, the rotating shaft is provided with a first limiting groove, and the support block is provided with at least one third groove at one end along the thickness direction of the rotating shaft. When one end of the support block along the thickness direction of the rotating shaft is positioned in the first limiting groove, the at least one third groove is connected to the groove wall of the first limiting groove by adhesive. By providing at least one third groove at one end of the support block located in the first limiting groove, the surface area of ​​the support block in the first limiting groove can be increased, thereby increasing the connection area between the adhesive and the end of the support block located in the first limiting groove, making the connection between the support block and the groove wall of the first limiting groove more secure.

[0014] In conjunction with the first aspect, in one possible implementation, the foldable device further includes a back shell located on the side of the hinge away from the foldable screen. The back shell has a second limiting groove, and the support block has at least one third groove at one end along the thickness direction of the hinge. When the end of the support block along the thickness direction of the hinge is positioned in the second limiting groove, the at least one third groove is connected to the groove wall of the second limiting groove by adhesive. By providing at least one fourth groove at the end of the support block located in the second limiting groove, the surface area of ​​the support block in the second limiting groove can be increased, thereby increasing the connection area between the adhesive and the end of the support block located in the second limiting groove, making the connection between the support block and the groove wall of the second limiting groove more secure.

[0015] In conjunction with the first aspect, in one possible implementation, the support block also has a boss at one end along the thickness direction of the rotating shaft, and the boss is connected to the adhesive. The boss is connected to the wall of the first limiting groove or the second limiting groove via the adhesive. By providing a boss at one end of the support block located in the first limiting groove or the second limiting groove, the connection area between the support block at the end of the first limiting groove or the second limiting groove and the adhesive can be increased, thereby improving the connection stability between the support block and the rotating shaft or the back shell.

[0016] Secondly, this application provides a support member, which includes a support block, a connector, and a soft rubber; the connector is connected to the support block, and a protrusion extending in a first direction is provided on the side of the connector away from the support block.

[0017] The protrusion includes a first end and a second end arranged opposite to each other in the second direction. The first end is provided with a first groove. The soft rubber is connected to the first end. At least a portion of the soft rubber is disposed in the first groove and connected to the groove wall of the first groove. The first groove is located between the two ends of the protrusion in the first direction, and the first direction intersects with the second direction.

[0018] In conjunction with the second aspect, in one possible implementation, in the third direction, the dimension of the protrusion at the end furthest from the support block is greater than or equal to 0.25 mm and less than or equal to 3 mm, and the third direction is perpendicular to the first direction.

[0019] In conjunction with the second aspect, in one possible implementation, the second end is provided with a second groove, the soft rubber is connected to the second end, at least a portion of the soft rubber is disposed in the second groove and connected to the groove wall surface of the second groove, the second groove being located between the two ends of the protrusion in the first direction.

[0020] In conjunction with the second aspect, in one possible implementation, the first and second ends are symmetrically arranged.

[0021] In conjunction with the second aspect, in one possible implementation, soft rubber wraps around at least a portion of the first and second ends.

[0022] In conjunction with the second aspect, in one possible implementation, the protrusion is provided with a through hole located between the first end and the second end, and at least a portion of the soft rubber is disposed in the through hole.

[0023] In conjunction with the second aspect, in one possible implementation, one end of the support block is provided with a third groove or boss. Attached Figure Description

[0042] To more clearly illustrate the technical solutions in the embodiments or background art of this application, the application will be further described in detail below with reference to the accompanying drawings.

[0043] This application provides a foldable electronic device, which can be a mobile phone, tablet, computer, television, etc.

[0044] Please see Figure 1 , Figure 2 and Figure 3The foldable electronic device 10 includes a foldable screen 100, a hinge 200, and a support 300. The foldable screen 100 includes a folding area 110 and two non-folding areas 120. The folding area 110 connects the two non-folding areas 120. The folding area 110 can be bent and deformed. The foldable screen 100 can have a folded state and a flattened state through the bending and deformation of the folding area 110.

[0045] A support member 300 is disposed on one side of the folding area along a first direction. The support member 300 is used to shield the edge of the folding area 110 on one side of the first direction, the axial direction of which is parallel to the axial direction of the rotating shaft 200. The support member 300 can be used to protect the folding area 110 and prevent other objects from directly colliding with the folding area 110.

[0046] In the embodiments provided in this application, the number of support members 300 in the foldable electronic device 10 is two. The two support members 300 are respectively located on both sides of the folding area 110 in the first direction. The two support members 300 can protect the folding area 110 on both sides of the first direction and prevent the folding area 110 from being bumped or knocked on both sides of the first direction.

[0047] Please see Figure 4 and Figure 5 The support member 300 includes a support block 310, a connector 320, and a soft rubber 330. The connector 320 is connected to the support block 310. The support block 310 is located on one side of the folding area 110 in a first direction. The side of the connector 320 away from the support block 310 has a protrusion 321 extending in the first direction. The protrusion 321 has a first end 3211 and a second end 3213 arranged opposite to each other in a second direction. The first end 3211 is connected to the soft rubber 330. The first end 3211 is uneven, which can increase the connection area between the first end 3211 and the soft rubber 330, thereby improving the connection stability between the soft rubber 330 and the first end 3211.

[0048] Please refer to the embodiments provided in this application. Figure 4 and Figure 6The first end 3211 has a first groove 3212, and at least a portion of the soft rubber 330 is disposed in the first groove 3212, allowing the soft rubber 330 to connect with the groove wall of the first groove 3212. Because the first end 3211 has the first groove 3212, when the first end 3211 is connected to the soft rubber 330, the presence of the first groove 3212 increases the connection area between the first end 3211 and the soft rubber 330, thereby improving the connection stability between the soft rubber 330 and the first end 3211, and further improving the connection stability between the soft rubber 330 and the protrusion 321. The first groove 3212 is located between the two ends of the protrusion 321 in the first direction, and at least a portion of the soft rubber 330 is disposed in the first groove 3212. The first groove 3212 can limit the movement of the soft rubber 330, thereby preventing the soft rubber 330 from detaching from the protrusion 321 in the first direction away from the support block 310.

[0049] Please see Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The projection of the first groove 3212 onto the thickness direction of the pivot 200 can be triangular, rectangular, arc-shaped, etc., and the first groove 3212 can also be other irregular shapes. This application does not limit the specific shape of the first groove 3212. The projection of the first end 3211 onto the thickness direction of the pivot 200 can be wavy, sawtooth-shaped, etc., and the first end 3211 can also be other irregular shapes. This application does not limit the specific shape of the first end 3211. The thickness direction of the pivot 200 is perpendicular to the first direction. When the foldable screen is in a flattened state, the thickness direction of the pivot 200 is in the same direction as the thickness direction of the foldable screen.

[0050] In the embodiments provided in this application, the soft adhesive 330 covers at least a portion of the protrusion 321, which increases the connection area between the soft adhesive 330 and the protrusion 321, thereby improving the connection stability between the soft adhesive 330 and the protrusion 321. The soft adhesive 330 is connected to the second end 3213, wherein the second end 3213 is uneven, which increases the connection area between the second end 3213 and the soft adhesive 330, thereby improving the connection stability between the soft adhesive 330 and the second end 3213.

[0051] Specifically, the second end 3213 is provided with a second groove 3214, and a portion of the soft rubber 330 can be disposed in the second groove 3214. The soft rubber 330 can connect with the groove wall surface of the second groove 3214 to increase the connection area between the soft rubber 330 and the second end 3213, thereby improving the connection stability between the soft rubber 330 and the second end 3213, and further improving the connection stability between the soft rubber 330 and the protrusion 321. The second groove 3214 is located between the two ends of the protrusion 321 in the first direction. The soft rubber 330 can also be at least partially disposed in the second groove 3214. The second groove 3214 can limit the soft rubber 330, thereby preventing the soft rubber 330 from detaching from the protrusion 321 towards the support block 310 in the first direction.

[0052] The projection of the second groove 3214 onto the thickness direction of the rotating shaft 200 can be triangular, rectangular, or arc-shaped, etc., and the second groove 3214 can also be other irregular shapes. This application does not limit the specific shape of the second groove 3214. The projection of the second end 3213 onto the thickness direction of the rotating shaft 200 can be wavy, sawtooth, etc., and the second end 3213 can also be other irregular shapes. This application embodiment does not limit the specific shape of the second end 3213.

[0053] In the embodiments provided in this application, when the connector 320 is connected to the soft rubber 330, an insert injection molding process can be used to connect the protrusion 321 and the soft rubber 330 together. For example, the connector 320 can be placed in a mold, and injection molding material to form the soft rubber 330 can be injected into the mold, causing the soft rubber 330 to be molded and injection molded onto the connector 320. When injecting the injection molding material into the mold, the injection molding material can be injected into the first groove 3212 and / or the second groove 3214, thereby enabling a stable connection between the protrusion 321 and the soft rubber 330.

[0054] Please refer to the embodiments provided in this application. Figure 7 and Figure 11While the first end 3211 of the protrusion 321 has a first groove 3212 and / or the second end 3213 of the protrusion 321 has a second groove 3214, a through hole 3215 can also be provided between the first end 3211 and the second end 3213. The through hole 3215 can penetrate the surface of the protrusion 321 away from the rotating shaft 200 and the surface of the protrusion 321 near the rotating shaft 200 along the thickness direction of the rotating shaft 200. A portion of the soft rubber 330 can be disposed in the through hole 3215, and the soft rubber 330 can be connected to the inner wall of the through hole 3215. While the protrusion 321 has a through hole 3215, by providing a first groove 3212 at the first end 3211 of the protrusion 321 and / or a second groove 3214 at the second end 3213, the connection area between the soft rubber 330 and the protrusion 321 can be further increased, and the connection stability between the protrusion 321 and the soft rubber 330 can be further improved.

[0055] Please refer to the embodiments provided in this application. Figure 12The soft rubber 330 wraps around the protrusion 321. When the foldable device is flattened, the size of the soft rubber 330 in the third direction is larger than the size of the protrusion 321. A portion of the soft rubber 330 is attached to the surface of the folding area 110 facing away from the pivot axis, and the soft rubber extends to the two non-folding areas 120 at both ends along the third direction. When the soft rubber is projected onto the folding area 110 along the thickness direction of the pivot axis, the size of the soft rubber 330 in the third direction is between 4mm and 7mm, and the size of the end of the protrusion 321 away from the support block 310 is between 0.25mm and 3mm. The ratio of the size of the end of the protrusion 321 away from the support block 310 to the size of the soft rubber in the third direction is between 3 and 8. At least a portion of the soft rubber 330 is disposed in the through hole 3215, so that when the soft rubber 330 is connected to the protrusion 321, a stable connection can be achieved between the soft rubber 330 and the connector 320. However, the through-hole 3215 will occupy the third-direction dimension of the protrusion 321, making the third-direction dimension of the protrusion 321 relatively large. For example, the third-direction dimension of the protrusion 321 is greater than 3mm. When the foldable screen is folded, the folding area 110 deforms. A portion of the folding area 110 will fold to the side of the first end 3211 away from the second end 3213 in the third-direction direction, and a portion of the folding area 110 will flip to the side of the second end 3213 away from the first end 3211 in the third-direction direction. It should be noted that the protrusion 321 is rigid. The material of the protrusion 321 can be stainless steel, aluminum alloy, titanium alloy, etc. The protrusion 321 can be a sheet structure. The protrusion 321 can be pressed against the surface of the folding area 110 away from the hinge 200 by the soft adhesive 330. When the foldable screen is folded, the soft adhesive 330 deforms with the folding area 110, but the area where the soft adhesive 330 connects to the protrusion 321 cannot deform. If the size of the protrusion 321 in the third direction is too large (e.g., greater than 3mm), the area where the soft rubber 330 connects to the protrusion 321 in the third direction will be relatively large, and the deformable area of ​​the soft rubber 330 will be relatively narrow. When the soft rubber 330 is deformed, the deformable areas of the soft rubber 330 on both sides of the protrusion 321 in the third direction will have rounded corners with small radii (small R-angles). During the long-term folding process of the foldable screen, the soft rubber 330 is prone to fatigue in the area where the small R-angles appear, which will lead to creases in the deformable area of ​​the soft rubber 330, which is not conducive to the aesthetics of the soft rubber 330.

[0056] Please refer to the embodiments provided in this application. Figure 6 , Figure 8 , Figure 9 and Figure 10Because the first end 3211 has a first groove 3212 and / or the second end 3213 has a second groove 3214, the connection area between the protrusion 321 and the soft rubber 330 can be increased. Eliminating the through hole 3215 on the protrusion 321 also ensures the stability of the protrusion 321 and the soft rubber 330 meets the requirements. Specifically, in the third direction, the dimension of the end of the protrusion 321 furthest from the support block 310 is greater than or equal to 0.25 mm and less than or equal to 3 mm. The dimension of the end of the protrusion 321 away from the support block 310 in the third direction can be 0.5mm, 1mm, 1.5mm, 2mm, or 2.5mm. Other values ​​are also possible. This application embodiment does not limit the specific value of the dimension of the end of the protrusion 321 away from the support block 310 in the third direction.

[0057] By removing the through hole 3215 on the protrusion 321, the first end 3211 and the second end 3213 can be closer together, thereby reducing the maximum size of the protrusion 321 in the third direction. This further reduces the size of the area where the soft rubber 330 connects to the protrusion 321 in the third direction. When the soft rubber 330 deforms with the folding area 110, the deformable area of ​​the soft rubber 330 becomes larger, which can increase the bending radius of the soft rubber 330 during deformation, thereby improving the situation where the deformable area of ​​the soft rubber 330 is prone to fatigue.

[0058] In the embodiments provided in this application, since the protrusion 321 is located on the side of the folding area 110 away from the pivot 200, and the soft adhesive 330 covering the protrusion 321 is attached to the surface of the foldable screen away from the pivot 200, the size of the protrusion 321 in the third direction is too large (e.g., greater than 3mm). This will also restrict the deformation of the folding area 110 when the foldable screen 100 is folded, resulting in rounded corners with small radii in the folding area 110 when the foldable screen 100 is folded, causing creases in the folding area 110, which is not conducive to the aesthetics of the foldable screen 100. Reducing the maximum size of the protrusion 321 in the third direction, and further reducing the size of the area where the soft adhesive 330 connects to the protrusion 321 in the third direction, can reduce the constraint of the protrusion 321 on the deformation of the folding area 110, thereby increasing the bending radius of the folding area 110 during deformation, and further improving the situation where the folding area 110 is prone to fatigue during deformation.

[0059] The maximum dimension of protrusion 321 in the third direction refers to the dimension of the projection of protrusion 321 in the third direction when it is projected onto support block 310 along the first direction. In the embodiments provided in this application, the maximum dimension of protrusion 321 in the third direction can be the dimension of the end of protrusion 321 away from support block 310 in the third direction.

[0060] In the embodiments provided in this application, the third direction is perpendicular to the first direction, and the second direction can be parallel to the third direction or form an angle with the third direction.

[0061] The perpendicularity defined in this application is not limited to absolute perpendicular intersection (with an included angle of 90°). Factors such as design tolerances and structural flatness are allowed to result in non-absolute perpendicular intersections. Small angular range errors are allowed, such as assembly error ranges of 80 to 100 degrees, which can all be understood as perpendicular relationships.

[0062] The third direction can be parallel to the second direction. The parallelism defined in this application is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism. It allows for situations where the parallelism is not absolute due to factors such as assembly tolerance, design tolerance, and structural flatness. It also allows for errors within a small angular range, such as within 10 degrees of assembly error. All of these can be understood as a parallel relationship.

[0063] In the embodiments provided in this application, the first end 3211 and the second end 3213 can be asymmetrically arranged, the positions of the first groove 3212 and the second groove 3214 are asymmetrical, or the sizes of the first groove 3212 and the second groove 3214 are different. Alternatively, the first end 3211 and the second end 3213 can be symmetrically arranged. In this case, the positions of the first groove 3212 and the second groove 3214 are symmetrical, and the sizes of the first groove 3212 and the second groove 3214 are the same. This results in a more balanced force distribution when the protrusion 321 connects to the soft adhesive 330, and better connection stability between the protrusion 321 and the soft adhesive 330.

[0064] In the embodiments provided in this application, the connector 320 further includes a body 322, which is connected to the protrusion 321. The body 322 can be integrally formed with the protrusion 321. The body 322 can be a sheet-like structure. The surface of the body 322 away from the protrusion 321 is connected to the support block 310, which can increase the connection area between the body 322 and the support block 310, thereby improving the connection stability between the body 322 and the support block 310. The body 322 can be welded or bonded to the support block 310.
