Description

Technical Field

[0001] This application relates to the field of folding device technology, specifically to a pressing component, a pressing bracket, and an electronic device. Background Technology

[0002] With the development of technology, various electronic devices have gradually become an indispensable part of life. Taking mobile phones as an example, in order to improve user experience and increase the functionality of mobile phones, the screens of mobile phones are getting larger and larger. In order to increase the screen area while reducing the size of the mobile phone, foldable phones have emerged. Current foldable phones use two main bodies connected by a folding mechanism to support the screen, and the screen can be opened or closed relative to each other, realizing the unfolded and folded state of the screen. Different circuit modules are located within the two main bodies. To enable electrical connection and communication between the two circuit modules within the two main bodies, current foldable phones use a through-axis flexible printed circuit board (FPC) to electrically connect the two circuit modules.

[0003] To ensure the sealing of the through-shaft hole where the through-shaft FPC passes through the body of the electronic device, a press-fit bracket is usually installed for sealing. However, the current press-fit bracket has poor sealing performance for the through-shaft hole. Utility Model Content

[0004] This application provides a pressing component, a pressing bracket, and an electronic device. The electronic device includes a housing, a through-shaft circuit board, and a pressing bracket. The through-shaft circuit board passes through a folding mechanism via a first mounting hole and a second mounting hole in the housing. The elastic element of the pressing bracket seals the first and second mounting holes, thereby improving the sealing performance.

[0005] In a first aspect, this application provides an electronic device. It includes: a housing comprising a first housing, a second housing, and a folding mechanism, the folding mechanism connecting the first and second housings, the folding mechanism being used to unfold or fold the first and second housings relative to each other, wherein the first housing has a first mounting hole, the second housing has a second mounting hole, the first and second mounting holes being located on opposite sides of the folding mechanism; a through-shaft circuit board, one end fixed to the first housing, the opposite end passing through the first mounting hole and the second mounting hole sequentially, and fixed to the second housing; and a first pressing bracket, mounted in the first mounting hole and fixing a portion of the through-shaft circuit board to the first housing, the first pressing bracket including a connected pressing member and an elastic member, at least a portion of the elastic member abutting between the pressing member and the inner wall of the first mounting hole, and at least a portion of the elastic member abutting between the pressing member and the through-shaft circuit board.

[0006] In this application, by setting a through-shaft circuit board, the circuits located in the first housing and the circuits located in the second housing can be made conductive, thereby realizing communication and power transmission. Through the design of the elastic element, when the first pressing bracket is installed at the first mounting hole, the elastic element can form a seal between the pressing component and the inner wall of the first mounting hole, improving the sealing performance at the first mounting hole. Furthermore, because the elastic element is elastic, by applying installation pressure to the first pressing bracket, the elastic element can undergo elastic compression deformation upon contact with the inner wall of the first mounting hole, and the elastic restoring force of the elastic element can further improve the sealing performance at the first mounting hole.

[0007] In this application, the elastic element is designed so that when the first pressing bracket is installed at the first mounting hole, the elastic element can form a seal between the pressing component and the through-shaft circuit board, thereby improving the sealing performance at the first mounting hole. Furthermore, because the elastic element is elastic, applying installation pressure to the first pressing bracket causes it to undergo elastic compression deformation upon contact with the through-shaft circuit board. The elastic restoring force of the elastic element further enhances the sealing performance at the first mounting hole.

[0008] In this application, the design of the elastic element can form a seal at the first mounting hole, thereby preventing external debris such as external liquids or dust from entering the housing, and thus preventing external debris from damaging or interfering with the components inside the housing.

[0009] The elastic element can wrap around the pressing part circumferentially to form a circumferential wrapping of the pressing part, thereby enabling the pressing part to form a seal between the entire circumference of the pressing part and the inner wall of the first mounting hole and the through-shaft circuit board, thus improving the sealing performance at the first mounting hole.

[0010] In some possible implementations, the portion of the elastic element that abuts against the inner wall of the first mounting hole has a first compression amount, which is in the range of 0.05 mm to 0.2 mm.

[0011] In this implementation, the first compression amount is designed as described above so that the portion of the elastic element that abuts against the inner wall of the first mounting hole has sufficient compression amount, thereby enabling the elastic element to have sufficient deformation recovery force to abut against the inner wall of the first mounting hole, which helps to improve the sealing performance between the first pressing bracket and the inner wall of the first mounting hole.

[0012] In some possible implementations, the portion of the elastic element that abuts against the through-shaft circuit board has a second compression amount, which is in the range of 0.05 mm to 0.2 mm.

[0013] In this implementation, the second compression amount is designed as described above so that the elastic element has sufficient compression at the point of contact with the through-shaft circuit board, thereby giving the elastic element sufficient deformation recovery force to contact the through-shaft circuit board and fix the through-shaft circuit board to the first wall, which helps to improve the sealing between the first pressing bracket and the through-shaft circuit board.

[0014] In some possible implementations, the pressing component includes a connected base plate and a protrusion. The protrusion protrudes from one side of the base plate, pointing from a first end to a second end of the base plate. The size of the base plate is larger than the size of the protrusion. The base plate is fixed to a first housing. At least a portion of an elastic element is disposed on the protrusion, which is disposed within a first mounting hole. At least a portion of the elastic element abuts against the inner wall of the first mounting hole and between the protrusion and the through-shaft circuit board.

[0015] In this implementation, at least a portion of the elastic element abuts against the inner wall of the first mounting hole, thereby improving the sealing performance between the protrusion and the inner wall of the first mounting hole. At least a portion of the elastic element also abuts against the protrusion and the through-shaft circuit board, further improving the sealing performance between the protrusion and the through-shaft circuit board.

[0016] In some possible implementations, the surface of the bump away from the base plate is provided with a first groove, the elastic element includes a first elastic part and a first protrusion, the first elastic part at least partially covers the bump, the first elastic part at least partially covers the bottom of the first groove, the first protrusion is located in the first groove and protrudes from the first elastic part, and the first protrusion abuts between the first elastic part and the through-shaft circuit board.

[0017] In this implementation, the design of the first groove avoids contact between the first pressing bracket and the movable part of the through-shaft circuit board, thus preventing noise problems. Furthermore, by covering the bottom of the first groove with the first elastic part, contact between the base plate and the through-shaft circuit board can be prevented, thus avoiding damage to the circuit board. The design of the first protrusion improves the sealing between the first elastic part and the through-shaft circuit board.

[0018] In some possible implementations, the thickness of the first elastic part is in the range of 0.2 mm to 0.5 mm.

[0019] In this implementation, the thickness of the first elastic portion is designed as described above, which provides sufficient deformation for the first elastic portion while avoiding excessive installation resistance or insufficient strength of the first pressing bracket. Specifically, the lower limit of the thickness of the first elastic portion provides sufficient deformation. When the overall size of the first pressing bracket remains unchanged, the upper limit of the thickness of the first elastic portion prevents the size of the pressing component from being too small, thus failing to provide sufficient support strength; when the overall size of the pressing component remains unchanged, the upper limit of the thickness of the first elastic portion prevents the overall size of the first pressing bracket from being too large, resulting in excessive installation resistance.

[0020] In some possible implementations, the height of the first protrusion protruding from the first elastic part is in the range of 0.2 mm to 1 mm.

[0021] In this implementation, the height of the first protrusion protruding from the first elastic part is designed as described above, which can provide sufficient deformation while avoiding excessive installation resistance of the first pressing bracket.

[0022] In some possible implementations, the inner wall of the first mounting hole has a convex wall, and at least a portion of the first elastic portion abuts against the convex wall.

[0023] In this implementation, the thickness design of the first elastic part provides sufficient deformation space for the contact between the elastic element and the convex wall, which is beneficial for the elastic element to form the first deformation at the contact with the convex wall, thereby improving the sealing performance of the contact between the first elastic part and the convex wall.

[0024] In some possible implementations, the inner wall of the first mounting hole includes a first wall, a second wall, a third wall, and a fourth wall. The first and third walls are arranged opposite each other, and the first, third, and folding mechanisms are arranged in the same direction. The third wall is closer to the folding mechanism than the first wall. The second and fourth walls are arranged opposite each other. The portion of the first wall near the opening of the first mounting hole is inclined away from the folding mechanism compared to the third wall. The third wall has a convex wall. The electronic device also includes a support plate and a first adhesive backing. The support plate is mounted on the portion of the first wall that is inclined relative to the third wall, and the first adhesive backing is mounted between the support plate and the through-shaft circuit board.

[0025] In this implementation, by setting the first wall portion to be inclined relative to the third wall, it is possible to avoid excessive bending of the through-shaft circuit board at the first wall, which could cause damage. It also provides a larger fixing surface for the through-shaft circuit board, which is beneficial to improving the stability of the through-shaft circuit board at the first mounting hole.

[0026] In some possible implementations, the protrusion further includes a first surface, a second surface, a third surface, and a fourth surface, arranged sequentially along the circumference of the protrusion. The first and third surfaces are positioned opposite each other, and the first and third surfaces, along with the folding mechanism, are arranged in the same direction. The third surface is closer to the folding mechanism than the first surface. The second and fourth surfaces are positioned opposite each other, and the surface connects the first, second, third, and fourth surfaces. The opening of the first groove is located on the surface and penetrates the first and third surfaces. A first elastic portion covers the first, second, third, and fourth surfaces, the surface, and the bottom of the first groove. A first protrusion extends in the direction from the second surface to the fourth surface. The portion of the first elastic portion covering the first surface abuts against the first wall, the portion of the first elastic portion covering the second surface abuts against the second wall, the portion of the first elastic portion covering the third surface abuts against the protruding wall, and the portion of the first elastic portion covering the fourth surface abuts against the fourth wall.

[0027] In this implementation, the thickness design of the first elastic portion provides sufficient deformation space for the elastic member at the contact point with the second wall, which facilitates the formation of the first deformation at this point. Similarly, the thickness design of the first elastic portion provides sufficient deformation space for the contact point between the elastic member and the fourth wall, which also facilitates the formation of the first deformation at this point. Finally, the thickness design of the first elastic portion provides sufficient deformation space for the contact point between the elastic member and the convex wall, which further facilitates the formation of the first deformation at this point.

[0028] In some possible implementations, the base plate has a first connecting surface and a second connecting surface. The first connecting surface connects the bottom of the first groove near the first surface to the edge of the base plate. The second connecting surface connects the third surface to the edge of the base plate. The first connecting surface is inclined relative to the second connecting surface, and the distance between the end of the first connecting surface near the edge of the base plate and the bottom surface of the base plate is smaller than the distance between the end of the first connecting surface near the first groove and the bottom surface of the base plate. The electronic device also includes a second adhesive backing, which is installed between the first connecting surface and the through-shaft circuit board.

[0029] In this implementation, the second adhesive can be disposed on opposite sides of the first adhesive on the through-shaft circuit board. The second adhesive can be bonded between the through-shaft circuit board and the first pressing bracket to improve the sealing performance and connection stability between the first pressing bracket and the through-shaft circuit board.

[0030] In this implementation, since the openings of the first connecting surface and the first wall near the first mounting hole are both inclined, and the inclined surfaces are in the same direction, the first connecting surface, the second adhesive, the through-shaft circuit board, the first adhesive, the support plate, and the openings of the first wall near the first mounting hole are stacked sequentially, and the fit between adjacent components is high, which helps to improve the sealing performance between the first wall, the through-shaft circuit board, and the first pressing bracket. Furthermore, the second adhesive also prevents direct contact between the first connecting surface and the through-shaft circuit board, thus avoiding damage to the through-shaft circuit board or the generation of abnormal noise.

[0031] In some possible implementations, the first shell has two first fixing holes, which are located on both sides of the first mounting hole along the arrangement direction of the second and fourth walls. The bottom plate has two second fixing holes, which are located at both ends of the bottom plate, and the two second fixing holes and the two first fixing holes are arranged opposite each other.

[0032] In this implementation, the two second fixing holes and the two first fixing holes are arranged opposite each other, which is beneficial to forming a fixed connection between the base plate and the first shell through the second fixing holes and the first fixing holes, so that the first pressing bracket is fixedly installed on the first shell, which can improve the sealing stability at the first mounting hole.

[0033] In some possible implementations, the elastic element includes a first elastic portion and a second protrusion, the second protrusion protruding from the first elastic portion. The first elastic portion at least partially covers the protrusion, and the second protrusion abuts against the inner wall of the first elastic portion and the first mounting hole.

[0034] In this implementation, the sealing performance between the press-fit component and the inner wall of the first mounting hole is further improved by the setting of the second protrusion.

[0035] In some possible implementations, the base plate has a connecting surface. The elastic element includes a first elastic portion and a second elastic portion connected together, the first elastic portion covering at least a portion of the protrusion, the second elastic portion covering at least a portion of the connecting surface, and the second elastic portion abutting between the connecting surface and the first shell.

[0036] In this implementation, by providing a second elastic part, the second elastic part can elastically abut against the connection surface and the first shell, thereby filling and sealing the gap between the base plate and the first shell, thus further improving the sealing performance at the first mounting hole.

[0037] The second elastic portion can cover the first connecting surface, allowing it to elastically abut against the first connecting surface and the through-shaft circuit board. This increases the sealing area between the press-fit component and the through-shaft circuit board, improving the sealing effect. Furthermore, there is no need to provide a second adhesive layer between the first connecting surface and the through-shaft circuit board, simplifying the process of installing the first press-fit bracket into the first mounting hole.

[0038] The second elastic part can cover the second connecting surface so that the third protrusion can elastically abut against the surface of the second connecting surface and the surface of the protrusion near the opening of the first mounting hole.

[0039] In some possible implementations, the second elastic part has a third protrusion that abuts against the first shell.

[0040] In this implementation, the sealing between the base plate and the first shell can be further improved by setting the third protruding post.

[0041] In some possible implementations, the elastic element also covers the surface of the bump away from the base plate.

[0042] In this implementation, the use of elastic elements can prevent collisions between the surface and the through-shaft circuit board, thus avoiding damage to the through-shaft circuit board or abnormal noise.

[0043] In some other possible implementations, the electronic device also includes a buffer that covers the surface of the bump away from the base plate.

[0044] In this implementation, the elastic element may not cover the surface of the bump. By providing a buffer on the surface of the bump, it is possible to prevent contact with the through-shaft circuit board and thus avoid abnormal noise.

[0045] In some possible implementations, the elastic element is connected to the press-fitted part via injection molding.

[0046] In this implementation, since the elastic element is formed by injection molding on the pressing element, the connection stability between the elastic element and the pressing element is high, thereby making the overall structural stability of the first pressing bracket high, which is beneficial to improving the sealing effect of the first pressing bracket on the first mounting hole.

[0047] In some possible implementations, the pressing member has multiple second grooves, the elastic member has multiple protrusions, the protrusions fill the second grooves, and the multiple protrusions correspond one-to-one with the multiple second grooves.

[0048] In this implementation, since the pressing component is provided with multiple second grooves, the injection-molded elastic component can form multiple protrusions, which can further enhance the bonding force between the elastic component and the second grooves, thereby improving the connection stability and thus helping to improve the sealing effect of the first pressing bracket on the first mounting hole.

[0049] In some possible implementations, the electronic device also includes a sealant. The sealant fills the space formed by the first pressing bracket, the first housing, and the elastic element; and / or, the sealant fills the space formed by the first pressing bracket, the through-shaft circuit board, and the elastic element.

[0050] In this implementation, by using sealant, the first mounting hole can be further sealed, which helps to further improve the sealing performance of the first mounting hole.

[0051] The sealant can be applied via dispensing. Due to the elastic element, the sealant can prevent uncured sealant from flowing into the housing during dispensing, thus preventing it from adhering to the through-shaft circuit board or other components inside the housing. This, in turn, avoids abnormal noises during the unfolding and folding of the housing.

[0052] In some possible implementations, the electronic device further includes a second pressing bracket, which is mounted in the second mounting hole and fixes the portion of the through-shaft circuit board to the second housing. The second pressing bracket includes a pressing element and an elastic element. The pressing element of the second pressing bracket is symmetrically arranged with respect to the folding mechanism with respect to the pressing element of the first pressing bracket, and the elastic element of the second pressing bracket is symmetrically arranged with respect to the elastic element of the first pressing bracket with respect to the folding mechanism.

[0053] In this implementation, by setting up a pressing bracket, a support plate, a first adhesive backing, and a second adhesive backing, the through-shaft circuit board can be partially fixed in the first mounting hole and the second mounting hole, and the first mounting hole and the second mounting hole can be sealed.

[0054] It should be noted that the symmetrical arrangement of the two pressing brackets is based on the relative positions of the through-shaft circuit board fixed at the first mounting hole and the through-shaft circuit board fixed at the second mounting hole. That is, the through-shaft circuit board is fixed on the inner wall of the first mounting hole away from the second mounting hole, and the through-shaft circuit board is fixed on the inner wall of the second mounting hole away from the first mounting hole. Understandably, some deviation is allowed in the symmetrical arrangement of the two pressing brackets, and it is not strictly limited here.

[0055] Secondly, this application provides a pressing bracket. The pressing bracket includes a pressing member and an elastic member, and the elastic member and the pressing member are connected.

[0056] In this application, the design of the elastic element ensures that when the pressing bracket is installed at the mounting hole, the elastic element can form a seal between the pressing component and the inner wall of the mounting hole, thereby improving the sealing performance at the mounting hole. Furthermore, because the elastic element is elastic, applying installation pressure to the pressing bracket causes it to undergo elastic compression deformation upon contact with the inner wall of the mounting hole. The elastic restoring force of the elastic element further enhances the sealing performance at the mounting hole.

[0057] In this application, the design of the elastic element allows it to form a seal between the press-fit component and the through-shaft circuit board when the press-fit bracket is installed at the mounting hole, thus improving the sealing performance at the mounting hole. Furthermore, because the elastic element is elastic, applying installation pressure to the press-fit bracket causes it to undergo elastic compression deformation upon contact with the through-shaft circuit board. The elastic restoring force of the elastic element further enhances the sealing performance at the mounting hole.

[0058] In this application, the design of the elastic element can form a seal at the mounting hole, thereby preventing external liquids or dust and other external debris from entering the housing, and thus preventing external debris from damaging or interfering with the components inside the housing.

[0059] It should be noted that the pressing bracket provided in this application can be applied to any hole structure that needs to be sealed. This application uses the application of the pressing bracket to the above-mentioned electronic device as an example to illustrate the technical effect.

[0060] The elastic element can wrap around the pressing part circumferentially to form a circumferential wrapping of the pressing part, thereby forming a seal between the pressing part and the inner wall of the mounting hole and the through-shaft circuit board, improving the sealing performance at the mounting hole.

[0061] In some possible implementations, the press-fit component includes a connected base plate and a protrusion, the protrusion protruding from one side of the base plate in a direction from a first end of the base plate to a second end, the base plate being larger than the protrusion. At least a portion of the elastic element is connected to the protrusion.

[0062] In this implementation, at least a portion of the elastic element abuts against the inner wall of the mounting hole, thereby improving the sealing performance between the bump and the inner wall of the mounting hole. At least a portion of the elastic element abuts against the bump and the through-shaft circuit board, further improving the sealing performance between the bump and the through-shaft circuit board.

[0063] In some possible implementations, the surface of the protrusion away from the base plate has a first groove. The elastic element includes a first elastic portion and a first protrusion. The first elastic portion at least partially covers the protrusion, and the first elastic portion at least partially covers the bottom of the first groove. The first protrusion is located in the first groove and protrudes from the first elastic portion.

[0064] In this implementation, the design of the first groove avoids contact between the pressing bracket and the movable part of the through-shaft circuit board, thus preventing noise problems. Furthermore, by covering the bottom of the first groove with the first elastic part, contact between the base plate and the through-shaft circuit board can be prevented, thus avoiding damage to the circuit board. The design of the first protrusion improves the sealing between the first elastic part and the through-shaft circuit board.

[0065] In some possible implementations, the thickness of the first elastic part is in the range of 0.2 mm to 0.5 mm.

[0066] In this implementation, the thickness of the first elastic part, designed as described above, provides sufficient deformation while avoiding excessive installation resistance or insufficient strength of the pressing bracket. Specifically, the lower limit of the thickness of the first elastic part provides sufficient deformation. When the overall size of the pressing bracket remains constant, the upper limit of the thickness of the first elastic part prevents the pressing component from being too small, thus failing to provide sufficient support strength; when the overall size of the pressing component remains constant, the upper limit of the thickness of the first elastic part prevents the overall size of the pressing bracket from being too large, resulting in excessive installation resistance.

[0067] In some possible implementations, the height of the first protrusion protruding from the first elastic part is in the range of 0.2 mm to 1 mm.

[0068] In this implementation, the height of the first protrusion protruding from the first elastic part adopts the above design, which can provide sufficient deformation while avoiding excessive installation resistance of the pressing bracket.

[0069] In some possible implementations, the protrusion includes a first surface, a second surface, a third surface, and a fourth surface, which are arranged sequentially along the circumference of the protrusion. The first and third surfaces are positioned opposite each other, as are the second and fourth surfaces. The surfaces of the first, second, third, and fourth surfaces are connected. The opening of the first groove is located on the surface and penetrates through the first and third surfaces. A first elastic portion covers the first, second, third, and fourth surfaces, the surface, and the bottom of the first groove. The first protrusion extends in the direction from the second surface to the fourth surface.

[0070] In this implementation, the thickness design of the first elastic portion provides sufficient deformation space for the elastic member at the contact point with the second wall, which facilitates the formation of the first deformation at this point. Similarly, the thickness design of the first elastic portion provides sufficient deformation space for the contact point between the elastic member and the fourth wall, which also facilitates the formation of the first deformation at this point. Finally, the thickness design of the first elastic portion provides sufficient deformation space for the contact point between the elastic member and the convex wall, which further facilitates the formation of the first deformation at this point.

[0071] In some possible implementations, the base plate has a first connecting surface and a second connecting surface. The first connecting surface is connected between the bottom of the first groove near the first surface and the edge of the base plate. The second connecting surface is connected between the third surface and the edge of the base plate. The first connecting surface is inclined relative to the second connecting surface. The distance between the end of the first connecting surface near the edge of the base plate and the bottom surface of the base plate is smaller than the distance between the end of the first connecting surface near the first groove and the bottom surface of the base plate.

[0072] In some possible implementations, the base plate is provided with two second fixing holes, which are located at both ends of the base plate along the arrangement direction of the second and fourth surfaces.

[0073] In this implementation, since the openings of the first connecting surface and the first wall near the mounting hole are both inclined, and the inclined surfaces are in the same direction, the first connecting surface, the second adhesive, the through-shaft circuit board, the first adhesive, the support plate, and the openings of the first wall near the mounting hole are stacked sequentially, and the fit between adjacent components is high, which helps to improve the sealing performance between the first wall, the through-shaft circuit board, and the pressing bracket. Furthermore, the second adhesive also prevents direct contact between the first connecting surface and the through-shaft circuit board, thus avoiding damage to the through-shaft circuit board or the generation of abnormal noise.

[0074] In some possible implementations, the elastic element further includes a second protrusion that protrudes from the first elastic portion, and the second protrusion and the first protrusion are located on different sides of the first elastic portion.

[0075] In this implementation, the sealing performance between the press-fit component and the inner wall of the mounting hole is further improved by setting the second protrusion.

[0076] In some possible implementations, the base plate has a connecting surface. The elastic element includes a first elastic portion and a second elastic portion connected together, the first elastic portion covering at least a portion of the protrusion and the second elastic portion covering at least a portion of the connecting surface.

[0077] In this implementation, by providing a second elastic part, the second elastic part can elastically abut against the connection surface and the first shell, thereby filling and sealing the gap between the base plate and the first shell, thus further improving the sealing performance at the mounting hole.

[0078] The second elastic portion can cover the first connecting surface, allowing it to elastically abut against the first connecting surface and the through-shaft circuit board. This increases the sealing area between the press-fit component and the through-shaft circuit board, improving the sealing effect. Furthermore, there is no need to apply a second adhesive backing between the first connecting surface and the through-shaft circuit board, simplifying the process of installing the press-fit bracket into the mounting hole.

[0079] The second elastic part can cover the second connecting surface so that the third protrusion can elastically abut against the surface of the second connecting surface and the surface of the protrusion near the opening of the mounting hole.

[0080] In some possible implementations, the second elastic part has a third protrusion.

[0081] In this implementation, the sealing between the base plate and the first shell can be further improved by setting the third protruding post.

[0082] In some possible implementations, the elastic element also covers the surface of the bump away from the base plate.

[0083] In this implementation, the use of elastic elements can prevent collisions between the surface and the through-shaft circuit board, thus avoiding damage to the through-shaft circuit board or abnormal noise.

[0084] In some possible implementations, the elastic element is connected to the press-fitted part via injection molding.

[0085] In this implementation, since the elastic element is formed by injection molding on the pressing part, the connection stability between the elastic element and the pressing part is high, thereby making the overall structure of the pressing bracket highly stable and improving the sealing effect of the pressing bracket on the mounting hole.

[0086] In some possible implementations, the pressing member has multiple second grooves, the elastic member has multiple protrusions, the protrusions fill the second grooves, and the multiple protrusions correspond one-to-one with the multiple second grooves.

[0087] In this implementation, since the pressing part is provided with multiple second grooves, the injection-molded elastic part can form multiple protrusions, which can further enhance the bonding force between the elastic part and the second grooves, thereby improving the connection stability and thus helping to improve the sealing effect of the pressing bracket mounting hole.

[0088] Thirdly, this application provides a pressing member. The pressing member includes a connected base plate and a protrusion, the protrusion protruding from one side of the base plate in a direction pointing from a first end of the base plate to a second end, the size of the base plate being larger than the size of the protrusion. The protrusion has a plurality of second grooves.

[0089] In this application, since the press-fit part is provided with multiple second grooves, the injection-molded elastic part can form multiple protrusions, which can further enhance the bonding force between the elastic part and the second grooves, thereby improving the connection stability and thus helping to improve the sealing effect of the press-fit bracket mounting hole.

[0090] In this application, by providing an elastic element in the pressing component, a seal can be formed at the mounting hole, thereby preventing external debris such as external liquids or dust from entering the housing, and thus preventing external debris from damaging or interfering with the components inside the housing.

[0091] It should be noted that the pressing component provided in this application can be applied to any hole structure that needs to be sealed. This application uses the application of the pressing component to the above-mentioned electronic device as an example to illustrate the technical effect.

[0092] In some possible implementations, the bump includes a first surface, a second surface, a third surface, a fourth surface, and a surface. The first surface, the second surface, the third surface, and the fourth surface are connected end to end along the circumference of the bump. The first surface and the third surface are arranged opposite each other, the second surface and the fourth surface are arranged opposite each other, and the surface connects the first surface, the second surface, the third surface, and the fourth surface. The bump is provided with a first groove, the opening of which is located on the surface and penetrates the first surface and the third surface.

[0093] In this implementation, the design of the first groove avoids contact between the pressing bracket and the movable part of the through-shaft circuit board, thus preventing noise problems. Furthermore, by covering the bottom of the first groove with the first elastic part, contact between the base plate and the through-shaft circuit board can be prevented, thus avoiding damage to the circuit board. The design of the first protrusion improves the sealing between the first elastic part and the through-shaft circuit board.

[0094] In some possible implementations, the base plate has a first connecting surface and a second connecting surface. The first connecting surface is connected between the bottom of the first groove near the first surface and the edge of the base plate. The second connecting surface is connected between the third surface and the edge of the base plate. The first connecting surface is inclined relative to the second connecting surface. The distance between the end of the first connecting surface near the edge of the base plate and the bottom surface of the base plate is smaller than the distance between the end of the first connecting surface near the first groove and the bottom surface of the base plate.

[0095] In this implementation, since the openings of the first connecting surface and the first wall near the mounting hole are both inclined, and the inclined surfaces are in the same direction, the first connecting surface, the second adhesive, the through-shaft circuit board, the first adhesive, the support plate, and the openings of the first wall near the mounting hole are stacked sequentially, and the fit between adjacent components is high, which helps to improve the sealing performance between the first wall, the through-shaft circuit board, and the pressing bracket. Furthermore, the second adhesive also prevents direct contact between the first connecting surface and the through-shaft circuit board, thus avoiding damage to the through-shaft circuit board or the generation of abnormal noise.

[0122] The embodiments of this application are described below with reference to the accompanying drawings.

[0123] 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. "Multiple" refers to at least two.

[0124] The directional terms mentioned in the embodiments of this application, such as "upper", "lower", "inner", "outer", "top", "bottom", "side", etc., 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 element 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.

[0125] In the embodiments of this application, the relative positional relationships mentioned, such as parallel, perpendicular, and aligned, are defined in relation to the current technological level, rather than being absolutely strict. Slight deviations are permissible; approximations of parallelism, perpendicularity, or alignment are all 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.

[0126] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0127] Please refer to the following: Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of an electronic device 10 in an unfolded state according to an embodiment of this application; Figure 2 yes Figure 1 A schematic diagram of the electronic device 10 in a folded state; Figure 3 yes Figure 1 The diagram shows the structure of the electronic device 10 in an intermediate state.

[0128] In some embodiments, the electronic device 10 may include a screen 1 and a housing 2, with the screen 1 mounted on the housing 2. For example... Figure 1As shown, the shell 2 can be unfolded to the unfolded state. Figure 2 As shown, the housing 2 can also be folded into a folded state. Figure 3 As shown, the housing 2 can also be unfolded or folded to an intermediate state, which can be any state between the unfolded state and the folded state. The screen 1 moves with the housing 2, and the housing 2 can drive the screen 1 to unfold or fold, so that the electronic device 10 can be unfolded to the unfolded state or folded to the folded state. When the electronic device 10 is in the folded state, the screen 1 is located on the outside of the housing 2.

[0129] In this embodiment, when the electronic device 10 is in the unfolded state, the screen 1 is flattened and can display in full screen, giving the electronic device 10 a larger display area to improve the user's viewing and operating experience. When the electronic device 10 is in the folded state, its planar dimensions are smaller, making it easier for users to carry and store.

[0130] For example, the housing 2 may include a first housing 21, a second housing 22 and a folding mechanism 23. The folding mechanism 23 may connect the first housing 21 and the second housing 22 and is used to unfold or fold the first housing 21 and the second housing 22 relative to each other.

[0131] In some embodiments, screen 1 may integrate display and touch sensing functions. The display function of screen 1 is used to display images, videos, etc., and the touch sensing function of screen 1 is used to sense user touch actions to achieve human-computer interaction. For example, screen 1 includes a bendable display screen. The display screen may be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a flexible light-emitting diode (FLED) display screen, a MiniLED display screen, a MicroLED display screen, a Micro-OLED display screen, a quantum dot light-emitting diode (QLED) display screen, etc.

[0132] In some embodiments, the electronic device 10 may further include multiple components (not shown in the figures), which are installed inside the housing 2. These components may include, for example, a processor, internal memory, an external memory interface, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a communication module, a camera, an audio module, a speaker, a receiver, a microphone, a headphone jack, a sensor module, buttons, a motor, an indicator, and a subscriber identification module (SIM) card interface, etc.

[0133] It should be understood that in this embodiment, the electronic device 10 is described as having a two-fold structure, that is, the electronic device 10 includes two flat plate parts and a bent portion connecting the two flat plate parts; the two flat plate parts can rotate towards each other to overlap each other (corresponding to the folded state mentioned above), so that the electronic device 10 presents a two-layer form; the two flat plate parts can also rotate away from each other to flatten out (corresponding to the unfolded state mentioned above). In some other embodiments, the electronic device 10 may also have a three-fold or more-fold structure, that is, the electronic device 10 includes three or more flat plate parts, and two adjacent flat plate parts are connected by a bent portion, and two adjacent flat plate parts can rotate relative to each other to overlap each other or rotate away from each other to flatten out. When the electronic device 10 has a three-fold or more-fold structure, the structure of the electronic device 10 can be adapted to the description of the two-fold structure in this embodiment, and this application will not repeat it here.

[0134] Please refer to the following: Figure 4A and Figure 4B , Figure 4A yes Figure 1 A schematic diagram of the mounting portion structure of the housing 2 in some embodiments of the electronic device 10 shown; Figure 4B yes Figure 4A The diagram shown is a partial structural breakdown of the structure in some embodiments.

[0135] In some embodiments, the electronic device 10 may further include a pressing bracket 3, a through-shaft circuit board 4, a support plate 5, a first adhesive 6, and a second adhesive 7. The first housing 21 may have a first mounting hole 211, and the second housing 22 may have a second mounting hole 221, located on opposite sides of the folding mechanism 23. One end of the through-shaft circuit board 4 may be fixed to the first housing 21, and the other end may pass through the first mounting hole 211 and the second mounting hole 221 sequentially, and be fixed to the second housing 22. At the first mounting hole 211, the pressing bracket 3, the support plate 5, the first adhesive 6, and the second adhesive 7 work together to seal the first mounting hole 211 and partially fix the through-shaft circuit board 4. At the second mounting hole 221, the pressing bracket 3, the support plate 5, the first adhesive 6, and the second adhesive 7 work together to seal the second mounting hole 221 and partially fix the through-shaft circuit board 4.

[0136] In this embodiment, by setting the through-shaft circuit board 4, the circuit located in the first housing 21 and the circuit located in the second housing 22 can be connected, thereby realizing communication and power transmission. By setting the pressing bracket 3, the support plate 5, the first adhesive 6 and the second adhesive 7, the through-shaft circuit board 4 can be partially fixed in the first mounting hole 211 and the second mounting hole 221, and the first mounting hole 211 and the second mounting hole 221 can be sealed.

[0137] It should be noted that, Figure 4A The structure shown only illustrates a portion of the structure on which the housing 2 is installed. In other embodiments, the housing 2 may also have more or fewer structures installed.

[0138] For example, the pressing bracket 3 installed in the first mounting hole 211 and the pressing bracket 3 installed in the second mounting hole 221 can have the same structure. When the electronic device 10 is in the unfolded state, the pressing bracket 3 installed in the first mounting hole 211 and the pressing bracket 3 installed in the second mounting hole 221 can be symmetrically arranged relative to the folding structure.

[0139] It should be noted that the symmetrical arrangement of the two pressing brackets 3 is based on the relative positions of the through-shaft circuit board 4 fixed at the first mounting hole 211 and the through-shaft circuit board 4 fixed at the second mounting hole 221. That is, the through-shaft circuit board 4 is fixed with the inner wall of the first mounting hole 211 away from the inner wall of the second mounting hole 221, and the through-shaft circuit board 4 is fixed with the inner wall of the second mounting hole 221 away from the inner wall of the first mounting hole 211. It is understood that the symmetrical arrangement of the two pressing brackets 3 can allow for some deviation, and is not strictly limited here.

[0140] For ease of subsequent description, the pressing bracket 3 installed at the first mounting hole 211 is designated as the first pressing bracket 3a, and the pressing bracket 3 installed at the second mounting hole 221 is designated as the second pressing bracket 3b. The structure of the first pressing bracket 3a will be described in detail later; therefore, it is understood that the second pressing bracket 3b may include at least a portion of the structure of the first pressing bracket 3a.

[0141] Please refer to the following: Figures 5 to 7 , Figure 5 yes Figure 4A A partial structural diagram of the shell 2 in some embodiments is shown; Figure 6 yes Figure 4A The diagram shows the structure in some embodiments after being cut along line A1-A1; Figure 7 yes Figure 4A The diagram shows the structure after being cut along line A2-A2 in some embodiments.

[0142] Please see Figure 5 In some embodiments, the inner wall of the first mounting hole 211 may include a first wall 2111, a second wall 2112, a third wall 2113 and a fourth wall 2114. The first wall 2111 and the third wall 2113 are arranged opposite to each other. The first wall 2111, the third wall 2113 and the folding mechanism 23 are arranged in the same direction. The third wall 2113 is closer to the folding mechanism 23 than the first wall 2111. The second wall 2112 and the fourth wall 2114 are arranged opposite to each other.

[0143] The portion of the first wall 2111 near the opening of the first mounting hole 211 may be tilted toward the side away from the folding mechanism 23 relative to the third wall 2113.

[0144] The third wall 2113 may have a convex wall 2115.

[0145] The first shell 21 is provided with two first fixing holes 212, which are located on both sides of the first mounting hole 211 along the arrangement direction of the second wall 2112 and the fourth wall 2114.

[0146] Please see Figure 6 In some embodiments, the support plate 5 may be installed on the portion of the first wall 2111 that is inclined relative to the third wall 2113, and the first adhesive 6 may be installed between the support plate 5 and the through-shaft circuit board 4.

[0147] In this embodiment, by setting a portion of the first wall 2111 to be inclined relative to the third wall 2113, it is possible to avoid damage to the through-shaft circuit board 4 due to excessive bending at the first wall 2111, and it is also possible to provide a larger fixing surface for the through-shaft circuit board 4, which is beneficial to improving the stability of the installation of the through-shaft circuit board 4 at the first mounting hole 211.

[0148] For example, the second adhesive 7 can be disposed on opposite sides of the first adhesive 6 on the through-shaft circuit board 4. The second adhesive 7 can be bonded between the through-shaft circuit board 4 and the first pressing bracket 3a to improve the sealing performance and connection stability between the first pressing bracket 3a and the through-shaft circuit board 4.

[0149] Please refer to the following: Figure 6 and Figure 7 In some embodiments, the first pressing bracket 3a can fix a portion of the through-shaft circuit board 4 to the first housing 21. The first pressing bracket 3a may include a connected pressing member 31 and an elastic member 32. At least a portion of the elastic member 32 may abut between the pressing member 31 and the inner wall of the first mounting hole 211.

[0150] In this embodiment, the elastic element 32 is designed so that when the first pressing bracket 3a is installed at the first mounting hole 211, the elastic element 32 can form a seal between the pressing member 31 and the inner wall of the first mounting hole 211, thereby improving the sealing performance at the first mounting hole 211. Furthermore, because the elastic element 32 is elastic, by applying installation pressure to the first pressing bracket 3a, the elastic element 32 can undergo elastic compression deformation after contacting the inner wall of the first mounting hole 211. The elastic restoring force of the elastic element 32 can further improve the sealing performance at the first mounting hole 211.

[0151] In some embodiments, at least a portion of the elastic element 32 may abut between the press-fit element 31 and the through-shaft circuit board 4.

[0152] In this embodiment, the elastic element 32 is designed so that when the first pressing bracket 3a is installed at the first mounting hole 211, the elastic element 32 can form a seal between the pressing member 31 and the through-shaft circuit board 4, thereby improving the sealing performance at the first mounting hole 211. Furthermore, because the elastic element 32 is elastic, by applying installation pressure to the first pressing bracket 3a, the elastic element 32 can undergo elastic compression deformation after contacting the through-shaft circuit board 4. The elastic restoring force of the elastic element 32 can further improve the sealing performance at the first mounting hole 211.

[0153] In this embodiment, the design of the elastic element 32 can form a seal at the first mounting hole 211, thereby preventing external debris such as external liquids or dust from entering the interior of the housing 2, and thus preventing external debris from damaging or interfering with the components inside the housing 2.

[0154] For example, the elastic member 32 can wrap around the pressing member 31 circumferentially to form a circumferential wrapping of the pressing member 31, thereby enabling the pressing member 31 to form a seal between the entire circumference and the inner wall of the first mounting hole 211 and the through-shaft circuit board 4, thus improving the sealing performance at the first mounting hole 211.

[0155] For example, the elastic member 32 can elastically abut against the through-shaft circuit board 4 to fix the through-shaft circuit board 4 to the first wall 2111 to seal the gap between the portion of the through-shaft circuit board 4 located on the first wall 2111 and the pressing member 31.

[0156] The second adhesive 7 can be offset from the elastic element 32 and located on the side near the opening of the first mounting hole 211 at the contact point between the elastic element 32 and the through-shaft circuit board 4. This allows the second adhesive 7 to strengthen the seal at the through-shaft circuit board 4 and improve the sealing performance of the first mounting hole 211 at the first wall 2111. In some other embodiments, the second adhesive 7 may not be provided between the through-shaft circuit board 4 and the first pressing bracket 3a, and the seal between the pressing element 31 and the first wall 2111 may be achieved solely through the elastic element 32.

[0157] For example, the elastic member 32 can elastically abut against the first wall 2111, the second wall 2112, the third wall 2113 and the fourth wall 2114 respectively to seal the gap between the inner wall of the first mounting hole 211 and the pressing member 31.

[0158] The elastic contact between the elastic element 32 and the convex wall 2115 can be considered as the elastic contact between the elastic element 32 and the third wall 2113.

[0159] Please refer to the following: Figures 8A to 9A , Figure 8A yes Figure 4A The diagram shown is a schematic representation of the first pressing bracket 3a in some embodiments. Figure 8B yes Figure 8A A schematic diagram of the first pressing bracket 3a shown from another perspective; Figure 9A yes Figure 8A The diagram shown is a partial structural breakdown of the structure in some embodiments.

[0160] In some embodiments, the pressing member 31 may include a connected base plate 311 and a protrusion 312, the protrusion 312 protruding from one side of the base plate 311 in a direction from a first end of the base plate 311 to a second end, and the size of the base plate 311 being larger than the size of the protrusion 312.

[0161] It should be noted that the direction from the first end of the protrusion 312 to the second end refers to the direction from any first end of the base plate 311 to any other second end of the base plate 311. For example, the direction from the first end of the protrusion 312 to the second end can include the length direction, width direction, diagonal direction, etc. of the protrusion 312. Understandably, in the direction from the first end of the base plate 311 to the second end, the size of the base plate 311 is larger than the size of the protrusion 312. That is, in the arrangement direction of the base plate 311 and the protrusion 312, the orthographic projection of the protrusion 312 onto the base plate 311 all fall within the base plate 311.

[0162] For example, the elastic element 32 can wrap around the protrusion 312 circumferentially.

[0163] The protrusion 312 includes a first surface 3121, a second surface 3122, a third surface 3123, a fourth surface 3124, and a surface 3125. The first surface 3121, the second surface 3122, the third surface 3123, and the fourth surface 3124 are sequentially connected end-to-end along the circumference of the protrusion 312. The first surface 3121 and the third surface 3123 are positioned opposite each other, as are the second surface 3122 and the fourth surface 3124. The surface 3125 is located on the side of the protrusion 312 facing away from the base plate 311, and it connects the first surface 3121, the second surface 3122, the third surface 3123, and the fourth surface 3124. The elastic element 32 may cover the first surface 3121, the second surface 3122, the third surface 3123, the fourth surface 3124, and the surface 3125. In some other embodiments, the elastic element 32 may not cover the surface 3125.

[0164] The protrusion 312 may have a first groove 3126, the opening of which is located on surface 3125 and extends through the first surface 3121 and the third surface 3123. It should be noted that... Figure 9A The size and position of the first groove 3126 are for illustrative purposes only and can be adjusted according to actual applications. It is understood that in some other embodiments, the surface 3125 of the protrusion 312 may not have the first groove 3126.

[0165] For example, the base plate 311 may have a connecting surface 3111, which can connect the periphery of the base plate 311 to the periphery of the protrusion 312.

[0166] The connecting surface 3111 may include a first connecting surface 3111a and a second connecting surface 3111b. The first connecting surface 3111a is connected between the bottom 3127 of the first groove 3126 near the first surface 3121 and the edge of the base plate 311. The second connecting surface 3111b is connected between the third surface 3123 and the edge of the base plate 311.

[0167] The first connecting surface 3111a may be inclined relative to the second connecting surface 3111b, and the distance between the end of the first connecting surface 3111a near the edge of the base plate 311 and the bottom surface of the base plate 311 is smaller than the distance between the end of the first connecting surface 3111a near the first groove 3126 and the bottom surface of the base plate 311.

[0168] For example, the base plate 311 may be provided with two second fixing holes 3112, which are located at both ends of the base plate 311 along the arrangement direction of the second surface 3122 and the fourth surface 3124.

[0169] Please refer to the following: Figures 9A to 11 , Figure 9B yes Figure 8B The first pressing bracket 3a shown is cut open along line BB in some embodiments. Figure 10 yes Figure 6 The diagram shown illustrates the amount of compression of the elastic element 32 in some embodiments of the structure. Figure 11 yes Figure 7 The diagram shown illustrates the compression amount of the elastic element 32 in some embodiments of the structure.

[0170] It should be noted that, Figure 9B The base plate 311 and the protrusion 312 are divided by dashed lines, which can be understood as follows: Figure 9B The boundary between the base plate 311 and the protrusion 312 is not strictly defined. In some other embodiments, the boundary between the base plate 311 and the protrusion 312 may be located elsewhere.

[0171] Please see Figure 9A and Figure 9B In some embodiments, the elastic member 32 may include a first elastic portion 321 and a first protrusion 322. The first protrusion 322 may protrude from the first elastic portion 321. The first elastic portion 321 covers the first surface 3121, the second surface 3122, the third surface 3123, the fourth surface 3124, the surface 3125, and the bottom 3127 of the first groove 3126. The first protrusion 322 is located in the first groove 3126 and protrudes from the first elastic portion 321. The first protrusion 322 extends in the direction from the second surface 3122 to the fourth surface 3124.

[0172] For example, the thickness d0 of the first elastic portion 321 is in the range of 0.2 mm to 0.5 mm. For instance, the thickness d0 of the first elastic portion 321 can be, but is not limited to, 0.2 mm, or 0.25 mm, or 0.3 mm, or 0.35 mm, or 0.4 mm, or 0.45 mm, or 0.5 mm, or other values ​​between 0.2 mm and 0.5 mm.

[0173] In this embodiment, the thickness d0 of the first elastic part 321 adopts the above-described design, which can provide sufficient deformation for the first elastic part 321 while avoiding excessive installation resistance or insufficient strength of the first pressing bracket 3a. Specifically, the lower limit of the thickness d0 of the first elastic part 321 can provide sufficient deformation. When the overall size of the first pressing bracket 3a remains unchanged, the upper limit of the thickness d0 of the first elastic part 321 can prevent the size of the pressing part 31 from being too small, thus failing to provide sufficient support strength; when the overall size of the pressing part 31 remains unchanged, the upper limit of the thickness d0 of the first elastic part 321 can prevent the overall size of the first pressing bracket 3a from being too large, resulting in excessive installation resistance.

[0174] For example, the height h1 of the first protrusion 322 protruding from the first elastic portion 321 can be in the range of 0.2 mm to 1 mm. For instance, the height h1 of the first protrusion 322 protruding from the first elastic portion 321 can be, but is not limited to, 0.2 mm, or 0.3 mm, or 0.4 mm, or 0.5 mm, or 0.6 mm, or 0.7 mm, or 0.8 mm, or 0.9 mm, or 1 mm, or other values ​​between 0.2 mm and 1 mm.

[0175] In this embodiment, the height h1 of the first protrusion 322 protruding from the first elastic part 321 is designed as described above, which can provide sufficient deformation while avoiding excessive installation resistance of the first pressing bracket 3a.

[0176] Please see Figure 10 and Figure 11 In some embodiments, the portion of the elastic element 32 that abuts against the inner wall of the first mounting hole 211 may have a first compression amount, which is in the range of 0.05 mm to 0.2 mm. For example, the first compression amount may be, but is not limited to, 0.05 mm, or 0.08 mm, or 0.11 mm, or 0.14 mm, or 0.17 mm, or 0.2 mm, or other values ​​between 0.05 mm and 0.2 mm.

[0177] In this embodiment, the first compression amount is designed as described above so that the portion of the elastic member 32 that abuts against the inner wall of the first mounting hole 211 has sufficient compression amount, thereby enabling the elastic member 32 to have sufficient deformation recovery force to abut against the inner wall of the first mounting hole 211, which is beneficial to improving the sealing performance between the first pressing bracket 3a and the inner wall of the first mounting hole 211.

[0178] In some embodiments, the portion of the elastic element 32 that abuts against the through-shaft circuit board 4 may have a second compression amount, which is in the range of 0.05 mm to 0.2 mm. For example, the second compression amount may be, but is not limited to, 0.05 mm, or 0.08 mm, or 0.11 mm, or 0.14 mm, or 0.17 mm, or 0.2 mm, or other values ​​between 0.05 mm and 0.2 mm.

[0179] In this embodiment, the second compression amount is designed as described above so that the elastic member 32 has sufficient compression at the point of contact with the through-shaft circuit board 4, thereby giving the elastic member 32 sufficient deformation recovery force to contact the through-shaft circuit board 4 and fix the through-shaft circuit board 4 to the first wall 2111, thereby improving the sealing between the first pressing bracket 3a and the through-shaft circuit board 4.

[0180] Please see Figure 10 In some embodiments, the base plate 311 can be fixed to the first shell 21, the protrusion 312 is disposed in the first mounting hole 211, and at least a portion of the elastic member 32 abuts against the inner wall between the protrusion 312 and the first mounting hole 211 to improve the sealing between the protrusion 312 and the inner wall of the first mounting hole 211.

[0181] In some embodiments, at least a portion of the elastic element 32 abuts between the protrusion 312 and the through-shaft circuit board 4 to improve the sealing between the protrusion 312 and the through-shaft circuit board 4. The first surface 3121, the third surface 3123, and the folding mechanism 23 are arranged in the same direction, with the third surface 3123 closer to the folding mechanism 23 than the first surface 3121.

[0182] For example, the portion of the first elastic part 321 covering the third surface 3123 can abut against the convex wall 2115. The first deformation of the first elastic part 321 here can be found in [reference needed]. Figure 10 In d1, the first elastic part 321 is indented due to pressure. Figure 10 The dashed line in the figure illustrates the outer contour of the first elastic part 321 before deformation at the convex wall 2115.

[0183] In this embodiment, due to the design of the thickness d0 of the first elastic part 321, sufficient deformation space is provided at the abutment of the elastic member 32 and the convex wall 2115, which is beneficial for the elastic member 32 to form the first deformation at the abutment of the convex wall 2115.

[0184] For example, the portion of the first elastic part 321 covering the bottom 3127 of the first groove 3126 can be disposed opposite to the through-shaft circuit board 4, and the first protrusion 322 can abut between the first elastic part 321 and the through-shaft circuit board 4. The second deformation of the first protrusion 322 in this case can be found in [reference needed]. Figure 10In d1, the first protrusion 322 is dented due to pressure. Figure 10 The dashed line in the figure illustrates the outer contour of the first protrusion 322 before it deforms at the through-shaft circuit board 4.

[0185] In this embodiment, the design of the first protrusion 322 protruding from the height h1 of the first elastic part 321 provides sufficient deformation space for the elastic member 32 at the point of contact with the through-shaft circuit board 4, which is beneficial for the elastic member 32 to form the first deformation at the point of contact with the through-shaft circuit board 4.

[0186] In this embodiment, the design of the first groove 3126 allows for clearance of the through-shaft circuit board 4, thereby preventing the first pressing bracket 3a from contacting the movable part of the through-shaft circuit board 4 and causing abnormal noise. In addition, by covering the bottom 3127 of the first groove 3126 with the first elastic part 321, it is also possible to prevent the base plate 311 from contacting the through-shaft circuit board 4 and damaging the through-shaft circuit board 4.

[0187] The second adhesive 7 can be installed between the first connecting surface 3111a and the through-shaft circuit board 4.

[0188] In this embodiment, since the portions of the first connecting surface 3111a and the first wall 2111 near the opening of the first mounting hole 211 are both inclined, and the inclined surfaces are in the same direction, the first connecting surface 3111a, the second adhesive 7, the through-shaft circuit board 4, the first adhesive 6, the support plate 5, and the portion of the first wall 2111 near the opening of the first mounting hole 211 are stacked sequentially, and the fit between adjacent components is high, which helps to improve the sealing performance between the first wall 2111, the through-shaft circuit board 4, and the first pressing bracket 3a. In addition, the provision of the second adhesive 7 can also prevent direct contact between the first connecting surface 3111a and the through-shaft circuit board 4, thus avoiding damage to the through-shaft circuit board 4 or the generation of abnormal noise.

[0189] It should be noted that when the second adhesive backing 7 is not provided, the first connecting surface 3111a can be covered by the elastic element 32 to improve the sealing performance at this point.

[0190] Please see Figure 9A and Figure 11 For example, the portion of the first elastic part 321 covering the second surface 3122 can abut against the second wall 2112. The first deformation of the first elastic part 321 here can be seen in... Figure 11 In d3, the first elastic part 321 is dented due to pressure. Figure 11 The outline of the first elastic part 321 before deformation at the second wall 2112 is shown by dashed lines.

[0191] In this embodiment, due to the design of the thickness d0 of the first elastic part 321, sufficient deformation space is provided for the elastic member 32 at the abutment of the second wall 2112, which is conducive to the formation of the first deformation at the abutment of the elastic member 32 and the second wall 2112.

[0192] For example, the portion of the first elastic part 321 covering the fourth surface 3124 can abut against the fourth wall 2114. The first deformation of the first elastic part 321 here can be found in [reference needed]. Figure 11 In d4, the first elastic part 321 is dented due to pressure. Figure 11 The dashed lines in the diagram illustrate the outer contour of the first elastic part 321 and the fourth wall 2114 before deformation occurs at the point of contact.

[0193] In this embodiment, due to the design of the thickness d0 of the first elastic part 321, sufficient deformation space is provided at the abutment of the elastic member 32 and the fourth wall 2114, which is conducive to the formation of the first deformation at the abutment of the elastic member 32 and the fourth wall 2114.

[0194] For example, the two second fixing holes 3112 and the two first fixing holes 212 are arranged opposite each other, which is beneficial to form a fixed connection between the base plate 311 and the first shell 21 through the second fixing holes 3112 and the first fixing holes 212, so that the first pressing bracket 3a is fixedly installed on the first shell 21, which can improve the sealing stability at the first mounting hole 211.

[0195] Please refer to the following: Figure 12A and Figure 12B , Figure 12A yes Figure 4A The diagram shown illustrates a structure in which sealant 8 is provided in some embodiments. Figure 12B yes Figure 12A The diagram shows the structure after being cut along line CC in some embodiments.

[0196] In some embodiments, the electronic device 10 may further include a sealant 8, which may fill the space formed by the first pressing bracket 3a, the first shell 21 and the elastic member 32, and / or the sealant 8 may fill the space formed by the first pressing bracket 3a, the through-shaft circuit board 4 and the elastic member 32.

[0197] In this embodiment, by providing sealant 8, the first mounting hole 211 can be further sealed, which helps to further improve the sealing performance of the first mounting hole 211.

[0198] The sealant 8 can be applied via dispensing, for example, as shown in the following reference. Figure 12AAs shown, adhesive is applied along the periphery of the first pressing bracket 3a. The uncured sealant 8 can flow into the space formed by the first pressing bracket 3a, the first shell 21 and the elastic member 32 through its own fluidity. The sealant 8 can also fill the space formed by the first pressing bracket 3a, the through-shaft circuit board 4 and the elastic member 32. After curing, it forms the sealant 8.

[0199] In this embodiment, due to the setting of the elastic element 32, the elastic sealant 8 can block the uncured sealant 8 during the dispensing process, preventing the uncured sealant 8 from flowing into the interior of the housing 2, thereby preventing the sealant 8 from sticking to the through-shaft circuit board 4 or other components inside the housing 2, and thus preventing abnormal noise problems from occurring during the unfolding and folding of the housing 2.

[0200] Among them, the material of sealant 8 can be a hot melt adhesive or other waterproof adhesive that can be applied through a dispensing process.

[0201] It should be noted that, Figure 12B The position, size, and shape of the sealant 8 shown are for illustrative purposes only. The sealant 8 can be filled in any gap between the first pressing bracket 3a and the first shell 21, and its position, size, and shape are not limited. In some other embodiments, the electronic device 10 may not have the sealant 8.

[0202] Please refer to the following: Figure 9A , Figure 13A and Figure 13B , Figure 13A yes Figure 9A A schematic diagram of the elastic element 32 in the first pressing bracket 3a shown from another perspective; Figure 13B yes Figure 8A The diagram shows the structure of the first pressing bracket 3a cut along line DD in some embodiments.

[0203] In some embodiments, the elastic element 32 can be injection molded to the press-fit element 31. In other words, the first press-fit support 3a can be formed by injection molding based on the press-fit element 31.

[0204] In this embodiment, since the elastic element 32 is formed by injection molding on the pressing element 31, the connection stability between the elastic element 32 and the pressing element 31 is high, thereby making the overall structural stability of the first pressing bracket 3a high, which is beneficial to improving the sealing effect of the first pressing bracket 3a on the first mounting hole 211.

[0205] For example, the pressing member 31 may have a plurality of second grooves 313, and the elastic member 32 may have a plurality of protrusions 323, the protrusions 323 filling the second grooves 313, and the plurality of protrusions 323 corresponding one-to-one with the plurality of second grooves 313.

[0206] In this embodiment, since the pressing component 31 is provided with a plurality of second grooves 313, the injection-molded elastic component 32 can form a plurality of protrusions 323, which can further enhance the bonding force between the elastic component 32 and the second grooves 313, thereby improving the connection stability and thus helping to improve the sealing effect of the first pressing bracket 3a on the first mounting hole 211.

[0207] The location, number, and shape of the second groove 313 can be arbitrarily set, as long as they are conducive to improving the bonding force between the injection-molded elastic part 32 and the press-fit part 31.

[0208] The elastic element 32 can be made of elastic injection molding materials such as rubber or silicone (e.g., liquid silicone rubber).

[0209] In some other embodiments, the pressing component 31 and the elastic component 32 can be independent entities. In other words, the elastic component 32 is not formed on the pressing component 31 by injection molding, but is manufactured independently and then further connected to the pressing component 31. The elastic component 32 can be fixedly connected to the pressing component 31 by means of bonding, snap-fitting, threaded connection, etc.

[0210] Please refer to the following: Figure 14A and Figure 14B , Figure 14A yes Figure 8B The first pressing bracket 3a shown is cut open along line BB in some other embodiments; Figure 14B yes Figure 4A The diagram shows a structural schematic in some other embodiments after the structure shown is cut along line A1-A1. Wherein, Figure 14A The first pressing bracket 3a shown is installed on Figure 14B The first mounting hole is located at 211. It should be noted that... Figure 14A and Figure 14B The first pressing bracket 3a shown may include at least a portion of the structure of any of the first pressing brackets 3a in the foregoing embodiments, and the same structures will not be described again here.

[0211] In some embodiments, the elastic member 32 may further include a second protrusion 324, which protrudes from the first elastic portion 321 and may be located on a different side of the first elastic portion 321 from the first protrusion 322. The second protrusion 324 may abut against the inner wall of the first elastic portion 321 and the first mounting hole 211.

[0212] In this embodiment, the sealing performance between the press-fit member 31 and the inner wall of the first mounting hole 211 is further improved by the provision of the second protrusion 324.

[0213] For example, the second protrusion 324 can elastically abut against the protrusion 2115 or the third wall 2113. The deformation of the second protrusion 324 in this case can be found in [reference needed]. Figure 14B In d5, the second protrusion 324 is dented due to pressure. Figure 14B The dashed line in the diagram illustrates the outer contour of the second protrusion 324 before it deforms at this location.

[0214] It should be noted that, Figure 14B The convex wall 2115 in the middle can be compared with Figure 10 The protruding wall 2115 is shorter, and a better sealing effect is achieved by setting a second protruding post 324; or, the electronic device 10 may not have a protruding wall 2115, and the second protruding post 324 may directly and elastically abut against the third wall 2113.

[0215] Please refer to the following: Figure 15A and Figure 15B , Figure 15A yes Figure 8B A schematic diagram of the structure of the first pressing bracket 3a shown in some embodiments after being cut open along line BB; Figure 15B yes Figure 4A The diagram shows a structural schematic in some embodiments after the structure is cut along line A1-A1. Wherein, Figure 15A The first pressing bracket 3a shown is installed on Figure 15B The first mounting hole is located at 211. It should be noted that... Figure 15A and Figure 15B The first pressing bracket 3a shown may include at least a portion of the structure of any of the first pressing brackets 3a in the foregoing embodiments, and the same structures will not be described again here.

[0216] In some embodiments, the elastic element 32 may further include a second elastic portion 325 that covers at least a portion of the connecting surface 3111.

[0217] In this embodiment, by providing a second elastic part 325, the second elastic part 325 can elastically abut against the connection surface 3111 and the first shell 21, thereby filling and sealing the gap between the bottom plate 311 and the first shell 21, thereby further improving the sealing performance at the first mounting hole 211.

[0218] For example, the second elastic portion 325 may have a third protrusion 326, which may abut against the first shell 21.

[0219] In this embodiment, the sealing between the base plate 311 and the first shell 21 can be further improved by setting the third protrusion 326.

[0220] The second elastic portion 325 can cover the second connecting surface 3111b, allowing the third protrusion 326 to elastically abut against the surface of the second connecting surface 3111b and the surface of the protrusion 2115 near the opening of the first mounting hole 211. The deformation of the third protrusion 326 at this location can participate in... Figure 15B In d6, the third protrusion 326 is dented due to pressure. Figure 15B The dashed line in the diagram illustrates the outer contour of the third protrusion 326 before it deforms at this location.

[0221] It should be noted that, Figure 14B The convex wall 2115 in the middle can be compared with Figure 10 The protruding wall 2115 is shorter, so that there is a gap between the first elastic part 321 and the protruding wall 2115. By setting the third protruding post 326 to form a seal on the top side of the protruding wall 2115, the sealing path is changed; or, the electronic device 10 may not have the protruding wall 2115. In this case, the first pressing bracket 3a abuts against the outer surface of the first shell 21, and the third protruding post 326 elastically abuts against the outer surface of the first shell 21 to form a seal.

[0222] Please refer to the following: Figure 16A and Figure 16B , Figure 16A yes Figure 8B A schematic diagram of the structure of the first pressing bracket 3a shown in some embodiments after being cut open along line BB; Figure 16B yes Figure 4A The diagram shows a structural schematic in some embodiments after the structure is cut along line A1-A1. Wherein, Figure 16A The first pressing bracket 3a shown is installed on Figure 16B The first mounting hole is located at 211. It should be noted that... Figure 16A and Figure 16B The first pressing bracket 3a shown may include at least a portion of the structure of any of the first pressing brackets 3a in the foregoing embodiments, and the same structures will not be described again here.

[0223] In some embodiments, the second elastic portion 325 may cover the first connecting surface 3111a, so that the second elastic portion 325 can elastically abut against the first connecting surface 3111a and the through-shaft circuit board 4, thereby increasing the sealing area between the pressing member 31 and the through-shaft circuit board 4, which is beneficial to improving the sealing effect between the pressing member 31 and the through-shaft circuit board 4. In addition, there is no need to further provide a second adhesive 7 between the first connecting surface 3111a and the through-shaft circuit board 4, which simplifies the process of installing the first pressing bracket 3a into the first mounting hole 211.

[0224] It should be noted that in some other embodiments, the elastic member 32 may not have the first protrusion 322; and / or, the third protrusion 326 may elastically abut against the through-shaft circuit board.

[0225] Please refer to the following: Figure 17A and Figure 17B , Figure 17A yes Figure 8B A schematic diagram of the structure of the first pressing bracket 3a shown in some embodiments after being cut open along line BB; Figure 17B yes Figure 4A The diagram shows a structural schematic in some embodiments after the structure is cut along line A1-A1. Wherein, Figure 17A The first pressing bracket 3a shown is installed on Figure 17B The first mounting hole is located at 211. It should be noted that... Figure 17A and Figure 17B The first pressing bracket 3a shown may include at least a portion of the structure of any of the first pressing brackets 3a in the foregoing embodiments, and the same structures will not be described again here.

[0226] In some embodiments, the electronic device 10 may also include a buffer 9 that covers the surface 3125 of the bump 312.

[0227] In this embodiment, the elastic member 32 may not cover the surface 3125 of the protrusion 312. By providing the buffer member 9 on the surface 3125 of the protrusion 312, it is possible to prevent contact with the through-shaft circuit board 4 and thus prevent abnormal noise.

[0228] When the elastic member 32 does not completely cover the bottom 3127 of the first groove 3126, the buffer member 9 can cover the bottom 3127 of the first groove 3126 to prevent contact with the through-shaft circuit board 4 and thus prevent abnormal noise.

[0229] Among them, the cushioning component 9 can be made of Mylar or adhesive backing, etc.
