Technical Field

[0001] This application relates to the field of electronic device technology, and more specifically, to a hinge assembly, assembly method, and foldable electronic device. Background Technology

[0002] Foldable electronic devices combine flexible displays with hinges, offering a larger screen experience when unfolded compared to traditional electronic devices, while maintaining superior portability when folded compared to traditional mobile phones. The doors of foldable electronic devices are all one-piece panels, installed by a rotating slot design. However, due to size limitations, the assembly and disassembly of the doors and the housing frame are quite cumbersome. Therefore, improving the efficiency of foldable device assembly and disassembly is a pressing issue. Summary of the Invention

[0003] This application provides a hinge assembly, an assembly method, and an electronic device. The hinge assembly and assembly method provided by this application simplify the installation process of the hinge assembly, improve the efficiency of hinge assembly and disassembly, and reduce the cost of hinge assembly repair.

[0004] In a first aspect, a hinge assembly is provided for use in a foldable electronic device. The hinge assembly includes: a door panel, the door panel including a first part, a second part, and a connector, the first part extending along a first direction, the first part including an axially disposed first end and a second end, the second part being detachably connected to the first end via the connector, the first direction being the axial direction of the hinge assembly; and a first housing support, the door panel being rotatably connected to the first housing support via the second part.

[0005] Based on the above technical solution, by designing the door panel as two separate parts, the installation sequence of the door panel during the installation of the hinge assembly can be changed, which is beneficial to improving the efficiency of the hinge assembly and disassembly.

[0006] In conjunction with the first aspect, in some implementations of the first aspect, the first housing support is provided with a first mounting groove at one end along the first direction, and the second part is accommodated in the first mounting groove.

[0008] In conjunction with the first aspect, in some implementations of the first aspect, the second part includes a first groove, the first end portion being located in the first groove, the depth of the first groove being greater than or equal to the thickness of the first end portion.

[0009] Based on the above technical solution, after the first end is installed into the first groove, since the depth of the first groove is greater than or equal to the thickness of the first end, the thickness of the door panel will not be too thick, which is beneficial to reducing the thickness of the hinge assembly.

[0010] In conjunction with the first aspect, in some implementations of the first aspect, the first portion includes a first protrusion projecting toward the first housing support, the first protrusion extending along the first direction from the second end toward the first end; the first housing support includes a second mounting groove in which the first protrusion is located, the second mounting groove including an open end on one side along the first direction and a stop end on the other side.

[0011] Based on the above technical solution, when the door panel is installed on the first housing bracket, it can be positioned by the first protrusion and the second mounting groove, which helps to improve the convenience of assembling and disassembling the pivot assembly.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the shape of the first protrusion includes an arcuate shape, and the second mounting groove includes an arcuate groove corresponding to the first protrusion.

[0013] Based on the above technical solution, after the door panel and the first housing bracket are installed, the door panel and the first housing bracket can rotate due to the arc-shaped surface of the first protrusion, thereby improving the flexibility of the pivot assembly.

[0015] In some possible implementations, the second housing support is provided with a third mounting groove at one end along the first direction, and the second end is accommodated in the third mounting groove.

[0016] Based on the above technical solution, since the first base and the second base are fixedly connected and the door panel is two separate parts, the hinge assembly can avoid damaging the first base and the second base when disassembling, and the door panel can be removed from the hinge assembly, which improves the convenience of disassembling the hinge assembly and reduces the cost of repairing the hinge assembly.

[0017] In conjunction with the first aspect, in some implementations of the first aspect, the first end portion includes a first through hole, the second portion includes a second through hole, and the connector passes through the first through hole and the second through hole to connect the first portion and the second portion.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, the connector includes any one of a rivet, a pin, or a screw.

[0019] Based on the above technical solution, the first part and the second part are connected by the first through hole of the first part and the second through hole of the second part and the connector, which makes the connection between the first part and the second part more reliable, and the first part and the second part can be separated by removing the connector, thus improving the flexibility of the shaft assembly during installation and disassembly.

[0020] Secondly, an assembly method is provided for a pivot assembly, the pivot assembly comprising: a door panel including a first part, a second part, and a connector, the first part extending along a first direction, the first part including an axially disposed first end and a second end, the second part being detachably connected to the first end via the connector, the first direction being the axial direction of the pivot assembly; a first housing bracket, the door panel being rotatably connected to the first housing bracket via the second part, the first housing bracket having a first mounting groove at one end along the first direction, the second part being accommodated in the first mounting groove; the method comprising: placing the second part in the first mounting groove of the first housing bracket; sliding the first end of the first part toward the second part along the first direction until it contacts the second part; and connecting the first part and the second part via the connector.

[0021] Based on the above technical solution, the door panel can be pushed into the first housing bracket and the first base in the first direction during the installation of the pivot assembly, avoiding the need to slide the door panel into the first housing bracket in the second direction, which can improve the convenience and efficiency of the pivot assembly assembly process.

[0022] In conjunction with the second aspect, in some implementations of the second aspect, the method further includes: during the process of sliding the first end of the first portion toward the direction of the second portion to contact the second portion, pushing the first protrusion from the open end into the second mounting groove, and causing the first protrusion to contact the stop end; wherein the rotating shaft assembly further includes: the first portion including the first protrusion protruding toward the first housing support, the first housing support including the second mounting groove, the second mounting groove including the open end on one side along the first direction and the stop end on the other side.

[0023] Based on the above technical solution, during the installation of the hinge assembly, the cooperation between the first protrusion and the second mounting groove facilitates the accuracy of the door panel positioning during installation and improves the efficiency of the hinge assembly installation.

[0024] In conjunction with the second aspect, in some implementations of the second aspect, the method further includes: before placing the second part in the first mounting groove of the first housing bracket, connecting the first housing bracket to the first base, connecting the second housing bracket to the second base, and fixing the first base to the second base; wherein the rotating shaft assembly further includes: the first base, the first housing bracket being rotatably or slidably connected to the first base; the second housing bracket, the first housing bracket and the second housing bracket being arranged along the first direction; the door panel being rotatably connected to the second housing bracket through the second end; and the second base, the first base and the second base being arranged along the first direction, the second base being rotatably or slidably connected to the second housing bracket.

[0025] Based on the above technical solution, during the installation of the hinge assembly, due to the detachable design of the door panel, the door panel can be the last component installed into the hinge assembly. During the disassembly of the hinge assembly, the door panel can be removed from the hinge assembly first, avoiding damage to the first and second bases, improving the efficiency of the hinge assembly during installation and disassembly, and reducing the cost of repairing the hinge assembly.

In the embodiments of this application, the y-axis is also referred to as the first direction, the x-axis as the second direction, and the z-axis can be the thickness direction of the foldable electronic device. It is understood that the coordinate system settings of the foldable electronic device can be flexibly set according to actual needs, and are not specifically limited here.

[0064] Figure 1 This is a schematic diagram of the structure of a foldable electronic device provided in an embodiment of this application. The foldable electronic device can be a mobile phone, tablet computer, watch, e-reader, laptop computer, wearable device, or other electronic device with folding functionality. Figure 1 The illustrated embodiment uses a foldable phone as an example.

[0065] like Figure 1As shown, the foldable electronic device 100 may include a flexible display screen 110 and a housing assembly 120. The housing assembly 120 has a receiving space for accommodating the components of the foldable electronic device 100. The housing assembly 120 also serves to protect and support the foldable electronic device 100. The flexible display screen 110 is disposed in the receiving space of the housing assembly 120 and connected to the housing assembly 120.

[0066] The flexible display screen 110 may include a first display unit 111, a second display unit 112, and a foldable display unit 113. The foldable display unit 113 may be connected between the first display unit 111 and the second display unit 112.

[0067] The housing assembly 120 may include a first housing 121, a second housing 122, and a hinge assembly 123. The first housing 121 supports a first display unit 111, and the second housing 122 supports a second display unit 112. The hinge assembly 123 connects the first housing 121 and the second housing 122 and supports a foldable display unit 113. The hinge assembly 123 enables rotation between the second housing 122 and the first housing 121 to support the flexible display screen 110 switching between an unfolded state and a folded state.

[0068] The first housing 121 may include a first middle frame 1211 and a first back cover 1212 connected together. The first display portion 111 of the flexible display screen 110 is supported on the first middle frame 1211 of the first housing 121. The first back cover 1212 is located on the side of the first middle frame 1211 away from the first display portion 111, and the first back cover 1212 can be replaced by a display screen (e.g., an LCD display screen, an OLED display screen, etc.). A receiving cavity is formed between the first middle frame 1211 and the first back cover 1212, which is used to accommodate electronic components such as a motherboard, a camera module, and a battery. Based on this, the first housing 121 can be connected to the hinge assembly 123 via the first middle frame 1211, or it can be connected to the hinge assembly 123 via the first back cover 1212.

[0069] Similarly, the second housing 122 may also include a second middle frame 1221 and a second back cover 1222 connected together. The second display portion 112 of the flexible display screen 110 is supported on the second middle frame 1221 of the second housing 122. The second back cover 1222 is located on the side of the second middle frame 1221 away from the second display portion 112, and the second back cover 1222 may also be replaced by a display screen (e.g., an LCD display screen, an OLED display screen, etc.). A receiving cavity is formed between the second middle frame 1221 and the second back cover 1222, which is used to accommodate electronic components such as sub-boards, speaker modules, arrays, and batteries. Based on this, the second housing 122 can be connected to the pivot assembly 123 via the second middle frame 1221, or it can be connected to the pivot assembly 123 via the second back cover 1222.

[0070] Figure 1 The foldable electronic device 100 shown is in an unfolded state. In the unfolded state, the angle between the first back cover 1212 and the second back cover 1222 can be approximately 180°. That is, in... Figure 1 In the unfolded state shown, the flexible display screen 110 has a first display unit 111, a foldable display unit 113, and a second display unit 112 arranged sequentially along the x-axis, allowing the foldable electronic device 100 to fold laterally. In other embodiments, when the flexible display screen 110 is in the unfolded state, the first display unit 111, the foldable display unit 113, and the second display unit 112 can also be arranged sequentially along the y-axis, allowing the foldable electronic device 100 to fold vertically. When the flexible display screen 110 is in the unfolded state, it enables large-screen display, providing users with richer information and a better user experience.

[0071] Figure 2 yes Figure 1 This is a schematic diagram illustrating one possible folded state of the foldable electronic device. Wherein, Figure 2 The foldable electronic device 100 is shown in its inward folded state. Figure 2 The inward folding state shown can be, for example, a left-right inward folding state or a top-bottom inward folding state. (The following is in conjunction with...) Figure 1 and Figure 2 This describes one possible folding state of the foldable electronic device 100.

[0072] In this application, the foldable electronic device 100 being in a folded state can mean that the foldable electronic device 100 is currently bent, and the degree of bending of the foldable electronic device 100 is at its maximum. At this time, the first back cover 1212 and the second back cover 1222 can be arranged parallel to each other, spaced apart from each other, and facing each other, and the distance between the first back cover 1212 and the second back cover 1222 is the minimum; similarly, the first display unit 111 and the second display unit 112 can be arranged parallel to each other, spaced apart from each other, and facing each other, and the height between the first display unit 111 and the second display unit 112 is the minimum. At this time, the first display unit 111 and the second display unit 112 can be considered to be located on different planes.

[0073] Please see Figure 1 and Figure 2 When the foldable electronic device 100 is in the inward folded state, the first back cover 1212 and the second back cover 1222 can approach each other, and the first display unit 111 and the second display unit 112 can approach each other. The first back cover 1212, the second back cover 1222, and the hinge assembly 123 can form a screen-accommodating area for accommodating the flexible display screen 110. That is, the flexible display screen 110 can be accommodated in the space between the first back cover 1212 and the second back cover 1222.

[0074] In another possible implementation, the foldable electronic device 100 can also be folded outwards. When the foldable electronic device 100 is in the outward-folded state, the first back cover 1212 and the second back cover 1222 can be brought close to each other, and the first display unit 111 and the second display unit 112 can be brought close to each other. The first display unit 111, the second display unit 112, and the foldable display unit 113 can form a housing area for accommodating the first back cover 1212, the second back cover 1222, and the hinge assembly 123. That is, the first back cover 1212, the second back cover 1222, and the hinge assembly 123 can be accommodated within the space between the first display unit 111 and the second display unit 112.

[0075] Figure 3 This is a partial structural diagram of a foldable electronic device 100.

[0076] It should be noted that, Figure 3 The schematic diagram illustrates some of the components included in the pivot assembly 123, the actual shape, size, position, and construction of which are not affected by the actual shape, size, position, and construction of the components. Figure 3 Restrictions.

[0077] In some possible implementations, such as Figure 3 As shown, the pivot assembly 123 may include a first base 124, a door panel 125, and a first housing bracket 126.

[0078] Two first housing brackets 126 are rotatably connected to opposite sides of the first base 124, allowing the pivot assembly 123 to switch between an unfolded and folded state. A door panel 125 is connected to the first housing brackets 126, so that the rotation of the first housing brackets 126 simultaneously rotates the door panel 125. The two first housing brackets 126 are respectively connected to the first housing 121 and the second housing 122. The mutual movement between the first housing brackets 126 drives the mutual movement of the first housing 121 and the second housing 122, allowing the foldable electronic device to switch between an unfolded and folded state. The first housing brackets 126 can be rotatably connected to the first base 124 via pivots, hinges, etc., but this embodiment does not limit this.

[0079] It is understood that in the pivot assembly 123 provided in this application embodiment, the first housing bracket 126 and the door panel 125 are located on one side of the first base 124 along the first direction, and the first housing bracket 126 and the door panel 125 are also provided on the other side of the first base 124 along the first direction. That is, the first base 124 is the center of the pivot assembly 123, and the first housing brackets 126 on both sides of the first base 124 along the first direction drive the door panels 125 on both sides to rotate.

[0080] The door panel 125 can be used to support part of the flexible display screen 110. The material of the door panel 125 includes, but is not limited to, plastic and metal. The door panel 125 can be in the form of a plate or a block, and no specific limitation is made here.

[0081] It should be noted that the first base 124 and the first housing bracket 126 are located on the side of the door panel 125 that faces away from the flexible display screen 110.

[0082] The door panel 125 is an important component of the hinge assembly 123 of the foldable electronic device 100. When the foldable electronic device 100 is in the unfolded state, the door panel 125 provides physical support for the flexible display screen 110, ensuring the screen's flatness and stability. When the foldable electronic device 100 is in the folded state, the gaps between the door panels 125 provide space for the flexible display screen 110 to be rolled up, preventing damage to the screen due to excessive pressure.

[0083] In the assembly process of the foldable electronic device 100, an arc-shaped protrusion is usually designed on the door panel 125 and a sliding groove is designed on the housing support. The door panel and the housing support are assembled together by rotation.

[0084] The embodiments of this application are described with reference to one side of the rotating shaft assembly, and the other side of the rotating shaft assembly along the first direction is also applicable to the description of the embodiments of this application.

[0085] Figure 4aThis is an exploded schematic diagram of a rotating shaft assembly provided in an embodiment of this application. Figure 4b This is an exploded schematic diagram of a rotating shaft assembly provided in an embodiment of this application.

[0086] Figure 4a The pivot assembly 123 shown includes a first housing bracket 126, a second housing bracket 128, a door panel 125, a first base 124, and a second base 127.

[0087] The first housing bracket 126 and the second housing bracket 128 are arranged along a first direction on the same side of the door panel 125, and the first base 124 and the second base 127 are arranged along the first direction on the opposite side of the door panel 125. Since the door panel 125 adopts an integrated design, during the assembly of the hinge assembly 123, the first housing bracket 126, the first base 124, and the door panel 125 must be assembled first, and then the second housing bracket 128 and the second base 127 must be assembled together to complete the assembly of the hinge assembly 123. Alternatively, the second housing bracket 128, the second base 127, and the door panel 125 can be assembled first, and then the first housing bracket 126 and the first base 124 can be assembled together to complete the assembly of the hinge assembly 123.

[0088] It should be noted that in the foldable electronic device 100, the first base 124 and the first housing support 126 are located on the side of the door panel 125 away from the flexible display screen 110, and the second base 127 and the second housing support 128 are located on the side of the door panel 125 away from the flexible display screen 110.

[0089] like Figure 4a and Figure 4b As shown, the first housing bracket 126 and the first base 124 are first connected, and then a portion of the door panel 125 is connected to the first housing bracket 126. The connection between the door panel 125 and the first housing bracket 126 can be achieved through an arc-shaped protrusion on the door panel 125 and a sliding groove on the first housing bracket 126, allowing the door panel 125 to slide into the first housing bracket 126 along a second direction. Figure 4a As shown, a portion of the door panel 125 slides into a groove on the first housing bracket 126 in the direction indicated by the arrow.

[0090] After the assembly of the hinge assembly 123 is halfway complete, the second housing bracket 128 and the second base 127 need to be connected, and then the other part of the door panel 125 is installed to the second housing bracket 128. At this time, attention must be paid to the sliding installation between the door panel 125 and the second housing bracket 128, as well as the possible interference at the connection position between the first base 124 and the second base 127. Therefore, the one-piece design of the door panel 125 is very disadvantageous for the installation of the hinge assembly 123.

[0091] To ensure the stability of the pivot assembly 123, the first base 124 and the second base 127 need to be fixedly connected, for example, by welding or gluing. After the pivot assembly 123 is installed, the first base 124 and the second base 127 cannot be disassembled without destructive disassembly. This means that if the door panel 125 needs to be removed during the maintenance of the pivot assembly 123, the first base 124 and the second base 127 need to be destructively disassembled, which results in excessively high maintenance costs for the pivot assembly 123.

[0092] To simplify the assembly and disassembly process of the hinge assembly, embodiments of this application provide a hinge assembly that simplifies the installation and disassembly of the door panel through a split design, thereby improving the efficiency of hinge assembly assembly and reducing the maintenance cost of the hinge assembly.

Figure 7 This is a schematic diagram of a door panel 125 provided in an embodiment of this application. Figure 8 yes Figure 7 A schematic exploded view of door panel 125 shown. Figure 9 This is a schematic diagram of a first housing support 126 provided in an embodiment of this application.

[0094] Understandable, Figure 5 The illustration schematically shows some of the components included in the pivot assembly. The actual shape, size, position, and construction of these components are not affected by the actual shape, size, position, and construction of the pivot assembly. Figure 5 Restrictions.

[0095] Combination Figures 5 to 9 The pivot assembly 123 includes a door panel 125, which includes a first part 1251, a second part 1252, and a connector 1253. The first part 1251 extends along a first direction and includes an axially arranged first end 1251a and a second end 1251b. The second part 1252 is detachably connected to the first end 1251a via the connector 1253. The first direction is the axial direction of the pivot assembly 123.

[0096] The pivot assembly 123 also includes a first housing bracket 126, and the door panel 125 is rotatably connected to the first housing bracket 126 via a second part 1252.

[0097] In some possible implementations, a first mounting groove 1261 is provided at one end of the first housing support 126 along a first direction, and a second part 1252 is accommodated in the first mounting groove 1261.

[0098] The second part 1252 may have a structure with an arc-shaped wall, and the first mounting groove 1261 may have a structure with an arc-shaped groove. Alternatively, the second part 1252 may have a structure with an arc-shaped groove, and the first housing support 126 may have a structure with an arc-shaped wall at one end along the first direction, so that the door panel 125 is rotatably connected to the first housing support 126 through the second part 1252.

[0099] In some possible implementations, the pivot assembly 123 may also include a first base 124, with the first housing support 126 rotatably or slidably connected to the first base 124.

[0100] It should be noted that the connection of the connector 1253 to the first end 1251a and the second part 1252 means that the connector 1253 can fix the first part 1251 and the second part 1252 together, so that the first part 1251, the second part 1252 and the connector 1253 become a whole, or the first part 1251, the second part 1252 and the connector 1253 can be separated into three independent parts by removing the connector 1253.

[0101] Figure 10a , Figure 10b , Figure 10c , Figure 10d , Figure 10e and Figure 10f This is a schematic diagram of the installation process of the rotating shaft assembly 123 provided in the embodiments of this application.

[0102] like Figure 10a and Figure 10b As shown, the first base 124 and the first housing bracket 126 can be assembled first, and then the second part 1252 of the door panel 125 can be installed into the first mounting groove 1261 of the first housing bracket 126. In other words, the door panel 125 can be installed after all other components of the pivot assembly 123 except the door panel 125 have been assembled.

[0103] like Figure 10c As shown, the second part 1252 of the door panel 125 has been installed into the first housing bracket 126. During installation, the first end 1251a of the first part 1251 of the door panel 125 can be slid in along a first direction toward the second part 1252, as shown. Figures 10c to 10d The changes, as smooth as... Figure 10e In the indicated state, the first end 1251a contacts the second part 1252, and the first part 1251 and the second part 1252 are connected by the connector 1253, thereby fixing the first part 1251 and the second part 1252 of the door panel 125 together, completing the installation of the door panel 125 and forming... Figure 10f The state shown.

[0104] In some possible implementations, the first end 1251a includes a first through hole 1251a1, the second part 1252 includes a second through hole 1252b, and the connector 1253 passes through the first through hole 1251a1 and the second through hole 1252b to connect the first part 1251 and the second part 1252.

[0105] Slide the first end 1251a of the first part 1251 of the door panel 125 toward the second part 1252 along the first direction, as follows: Figures 10c to 10d The changes, as smooth as... Figure 10e In the indicated state, the first end 1251a contacts the second part 1252, aligning the first through hole 1251a1 with the second through hole 1252b. Then, the connector 1253 passes through the first through hole 1251a1 and the second through hole 1252b, fixing the first part 1251 and the second part 1252 of the door panel together, thus completing the installation of the door panel 125 and forming... Figure 10f The state shown.

[0106] Based on the above technical solution, by designing the door panel as two separate parts, the installation sequence of the door panel during the installation of the hinge assembly can be changed, which is beneficial to improving the efficiency of the hinge assembly and disassembly.

[0107] In some possible implementations, the first portion 1251 of the door panel 125 further includes a first protrusion 1254 protruding toward the first housing support 126. The first protrusion 1254 extends along a first direction from the second end 1251b toward the first end 1251a. The first housing support 126 includes a second mounting groove 1262 in which the first protrusion 1254 is located. The second mounting groove 1262 includes an open end 1262a on one side along the first direction and a stop end 1262b on the other side along the first direction.

[0108] In some possible implementations, the shape of the first protrusion 1254 includes an arc shape, the arc surface of the first protrusion 1254 is tangent to the second direction, and the second mounting groove 1262 includes an arc-shaped groove corresponding to the first protrusion 1254.

[0109] Figure 11a This is a schematic diagram of the structure of a rotating shaft assembly 123 provided in an embodiment of this application. Figure 11b yes Figure 11a A schematic exploded diagram. Figure 11c yes Figure 11a A schematic exploded diagram. Figure 11d This is a schematic diagram of a first housing support provided in an embodiment of this application. Figure 11e yes Figure 11d A magnified view of a portion of the image. Figure 11f and Figure 11gThis is a schematic diagram of the installation process of the rotating shaft assembly 123 provided in the embodiments of this application. Figure 12a yes Figure 11f A schematic cross-sectional view of section AA. Figure 12b yes Figure 11g A schematic cross-sectional view of section BB.

[0110] Combination Figures 11a-12b As the first part 1251 slides toward the second part 1252 along the first direction, the first protrusion 1254 can enter through the open end 1262a of the second mounting groove 1262. During the sliding of the first part 1251 along the first direction, the first protrusion 1254 gradually approaches the stop end 1262b and then contacts or abuts against the stop end 1262b, i.e., from... Figure 11d The state shown has changed to Figure 11e The state shown completes the installation of the first part 1251 of the door panel 125. The first protrusion 1254 and the second mounting groove 1262 can be used to position the first part 1251 of the door panel 125 during installation with the first housing bracket 126.

[0111] When the first protrusion 1254 is arc-shaped and the second mounting groove 1262 includes an arc-shaped groove, the first protrusion 1254 and the second mounting groove 1262 can also enable the first housing bracket 126 and the door panel 125 to rotate relative to each other.

[0112] Based on the above technical solution, after the door panel and the first housing bracket are installed, the door panel and the first housing bracket can rotate due to the arc-shaped surface of the first protrusion, thereby improving the flexibility of the pivot assembly.

[0113] It should be noted that, Figure 11d The state of the rotating shaft assembly 123 shown can be compared with... Figure 10d correspond, Figure 11e The state of the rotating shaft assembly 123 shown can be compared with... Figure 10f and Figure 11a correspond.

[0114] In some possible implementations, there may be multiple first protrusions 1254 and multiple second mounting slots 1262.

[0115] Based on the above technical solution, when the door panel is installed on the first housing bracket, it can be positioned by the first protrusion and the second mounting groove, which helps to improve the convenience of assembling and disassembling the pivot assembly.

[0116] In some possible implementations, the second part 1252 includes a first groove 1252a, the bottom wall of which is away from the plane where the door panel 125 is located, and a second through hole 1252b located on the bottom wall of the first groove 1252a.

[0117] The first end portion 1251a is located in the first groove 1252a, and the depth of the first groove 1252a is greater than or equal to the thickness of the first end portion 1251a.

[0118] Still Figure 8 As shown, the second part 1252 is provided with a first groove 1252a. When the first part 1251 slides toward the second part 1252, the first end 1251a can enter the first groove 1252a of the second part 1252. Since the depth of the first groove 1252a is greater than or equal to the thickness of the first end 1251a, the dimension of the door panel 125 in the thickness direction will not increase, which can avoid the thickening of the hinge assembly 123 leading to the thickening of the foldable electronic device 100.

[0119] The first groove 1252a can also play a guiding and positioning role during the installation of the first part 1251, which is beneficial to the installation of the first part 1251.

[0120] Based on the above technical solution, after the first end is installed into the first groove, since the depth of the first groove is greater than or equal to the thickness of the first end, the thickness of the door panel will not be too thick, which is beneficial to reducing the thickness of the hinge assembly.

[0121] In some possible implementations, the pivot assembly 123 further includes a second housing support 128 and a second base 127. The first housing support 126 and the second housing support 128 are arranged along a first direction. The door panel 125 is rotatably connected to the second housing support 128 through a second end 1251b. The first base 124 and the second base 127 are arranged along the first direction. The second base 127 and the second housing support 128 are located on both sides of the door panel 125 along a second direction. The second base 127 and the second housing support 128 are rotatably or slidably connected. The first base 124 and the second base 127 are fixedly connected.

[0122] In some possible implementations, the second housing support 128 is provided with a third mounting groove 1281 at one end along the first direction, and the second end 1251b is accommodated in the third mounting groove 1281.

[0123] The second end 1251b may have a structure with an arc-shaped wall, and the third mounting groove 1281 may have a structure with an arc-shaped groove. Alternatively, the second end 1251b may have a structure with an arc-shaped groove, and one end of the second housing support 128 along the first direction may have a structure with an arc-shaped wall, so that the door panel 125 is rotatably connected to the second housing support 128 through the second end 1251b.

[0124] In some possible implementations, the first base 124 and the second base 127 may be fixedly connected by welding.

[0125] During the installation of the pivot assembly 123, the first base 124 and the first housing bracket 126 can be connected together first, and then the second base 127 and the second housing bracket 128 can be connected together. Then the first base 124 and the second base 127 can be connected. After the installation of the base and the housing bracket is completed, the second part 1252 of the door panel 125 can be installed in the first mounting groove 1261 of the first housing bracket 126. Then the first part 1251 can be slidably installed along the first direction until it contacts the second part 1252. Then the first part 1251 and the second part 1252 can be fixed by the connector 1253.

[0126] Based on the above technical solution, since the first base and the second base are fixedly connected and the door panel is two separate parts, the hinge assembly can avoid damaging the first base and the second base when disassembling, and the door panel can be removed from the hinge assembly, which improves the convenience of disassembling the hinge assembly and reduces the cost of repairing the hinge assembly.

[0127] Based on the above technical solution, the door panel 125 can be the last component installed in the pivot assembly 123. This avoids the possibility of interference between the first base 124 and the second base 127, which could cause damage to the first base 124 or the second base 127, when the door panel 125 is installed first. Furthermore, when removing the pivot assembly 123, the door panel 125 can be removed first, avoiding destructive disassembly of the base and reducing the cost of maintaining the pivot assembly 123.

[0128] It should be noted that since the second part of one end of the door panel along the first direction is installed in the first mounting groove, and the second end of the door panel is installed in the third mounting groove, it can be considered that the door panel is snapped onto the first housing bracket and the second housing bracket. Alternatively, along the first direction, the distance between the first mounting groove and the third mounting groove is approximately equal to the length of the door panel along the first direction. If the door panel were a one-piece design, one end of the door panel could not be pushed into the first mounting groove of the first housing bracket along the first direction.

[0129] In some possible implementations, the first housing support and the second housing support may be integral to form the first housing support, and the first base and the second base may be integral to form the first base. In this case, the first mounting groove and the third mounting groove are respectively provided on both sides of the first housing support along the first direction.

[0130] In some possible implementations, the connector 1253 can be a rivet that passes through the first through hole 1251a1 and the second through hole 1252b to rivet the first part 1251 and the second part 1252.

[0131] In some possible implementations, the connector 1253 can be a pin that passes through the first through hole 1251a1 and the second through hole 1252b to interference-connect the first part 1251 and the second part 1252.

[0132] In some possible implementations, the connector 1253 can be a screw, with the inner walls of the first through hole 1251a1 and the second through hole 1252b respectively having threads, and the screw passing through the first through hole 1251a1 and the second through hole 1252b to interference fit the first part 1251 and the second part 1252.

[0133] The embodiments of this application also provide an assembly method, which is applied to the rotating shaft assembly provided in any embodiment of this application.

[0134] The assembly method includes: placing the second part in the first mounting groove of the first housing bracket; sliding the first end of the first part toward the second part in the direction of the first direction until it contacts the second part; and connecting the first part and the second part by means of a connector.

[0135] Due to the split design of the door panel, the second part can be installed into the first mounting slot of the first housing bracket first, and then the first part can be connected to the second part.

[0136] Based on the above technical solution, the door panel can be pushed into the first housing bracket and the first base in the first direction during the installation of the pivot assembly, avoiding the need to slide the door panel into the first housing bracket in the second direction, which can improve the convenience and efficiency of the pivot assembly assembly process.

[0137] In some possible implementations, the assembly method further includes: pushing the first protrusion from the open end into the second mounting groove and making the first protrusion contact the stop end while sliding the first end of the first part toward the second part to contact the second part.

[0138] Based on the above technical solution, during the installation of the hinge assembly, the cooperation between the first protrusion and the second mounting groove facilitates the accuracy of the door panel positioning during installation and improves the efficiency of the hinge assembly installation.

[0139] In some possible implementations, the method further includes: connecting the first housing bracket to the first base, connecting the second housing bracket to the second base, and fixing the first base to the second base before placing the second part in the first mounting slot of the first housing bracket.

[0140] It should be noted that since the second part of one end of the door panel along the first direction is installed in the first mounting groove, and the second end of the door panel is installed in the third mounting groove, the door panel can be considered to be snapped onto the first housing bracket and the second housing bracket. If the door panel adopts a one-piece design, it is impossible to first install one end of the door panel into the first mounting groove of the first housing bracket.

[0141] Based on the above technical solution, during the installation of the hinge assembly, due to the detachable design of the door panel, the door panel can be the last component installed into the hinge assembly. During the disassembly of the hinge assembly, the door panel can be removed from the hinge assembly first, avoiding damage to the first and second bases, improving the efficiency of the hinge assembly during installation and disassembly, and reducing the cost of repairing the hinge assembly.

[0142] In some possible implementations, the assembly method further includes: passing the connector through the first through hole and the second through hole to connect the first part and the second part; wherein the first end includes the first through hole, the second part includes the second through hole, and the connector passes through the first through hole and the second through hole to connect the first part and the second part.

[0143] Based on the above technical solution, the first part and the second part are connected by the first through hole of the first part and the second through hole of the second part and the connector, which makes the connection between the first part and the second part more reliable, and the first part and the second part can be separated by removing the connector, thus improving the flexibility of the shaft assembly during installation and disassembly.

The first part 1251 extends along a first direction and includes an axially arranged first end 1251a and a second end 1251b. The second part 1252 is detachably connected to the first end 1251a through the connector 1253. The first direction is the axial direction of the hinge assembly 123. The door panel 125 is used to support the flexible display screen 110. A first housing support 126 is also provided, and the door panel 125 is rotatably connected to the first housing support 126 through the second part 1252.

[0146] In some possible implementations, the hinge assembly 123 of the foldable electronic device 100 further includes: a first base 124, a first housing support 126 rotatably or slidably connected to the first base 124, and the first housing support 126 and the first base 124 being located on the side of the door panel 125 away from the flexible display screen 110.

[0147] In some possible implementations, the hinge assembly 123 of the foldable electronic device 100 further includes: a second housing support 128, wherein the first housing support 126 and the second housing support 128 are arranged along a first direction, and a third mounting groove 1281 is provided at one end of the second housing support 128 along the first direction, and a second end 1251b is accommodated in the third mounting groove 1281; a second base 127, wherein the first base 124 and the second base 127 are arranged along the first direction, and the second base 127 is rotatably or slidably connected to the second housing support 128, and the first base 124 and the second base 127 are fixedly connected, and the second housing support 128 and the second base 127 are located on the side of the door panel 125 away from the flexible display screen 110.
