Description

Technical Field

[0001] This invention relates to a fixed structure, and more particularly to a disassembly and assembly mechanism and expansion equipment. Background Technology

[0002] Many electronic devices on the market use mounting structures to fix electronic devices to each other. For example, a bracket is used to fix a hard drive, optical drive or display adapter to a computer, or a substrate is used to attach a touch panel to a smartphone.

[0003] However, current electronic devices are usually installed inside electronic devices through fixed structures, making it difficult to replace electronic devices. Summary of the Invention

[0004] In view of the above, in some embodiments, an expansion device is provided, including a housing and a disassembly / assembly mechanism. The housing has a latching hole. The disassembly / assembly mechanism includes a transmission assembly and an operating component. The transmission assembly is disposed within the housing and includes a rotating component, a connecting component, and a latching component. The rotating component is pivotally connected to the housing, the connecting component connects the rotating component and the latching component, and a portion of the latching component is exposed in the latching hole. The operating component is disposed within the housing and connected to the transmission assembly. The operating component drives the transmission assembly, causing a portion of the latching component to be movably disposed within the latching hole.

[0005] In some embodiments, the transmission assembly further includes a thrust rod connected between the operating member and the rotating member. The operating member drives the thrust rod, causing the thrust rod to move in conjunction with the rotating member, the connecting member, and the latching member.

[0006] In some embodiments, the operating member is adapted to move between an initial position and an operating position, and the latching member is adapted to move between a first position and a second position. When the operating member moves from the initial position to the operating position, the operating member drives the transmission assembly to move, and the latching member moves from the first position to the second position.

[0007] In some embodiments, the buckle hole has an engaging surface, and when the buckle is in a first position, a portion of the buckle is close to the engaging surface, and when the buckle is in a second position, a portion of the buckle is away from the engaging surface.

[0008] In some embodiments, the rotating component may be a turntable, and the linkage may include a connecting rod. The two ends of the connecting rod are pivotally connected to the turntable and the latching component, respectively. When the operating component drives the rotating component to rotate, the rotating component drives the transmission component, causing the connecting rod to move the latching component from the first position to the second position.

[0009] In some embodiments, the disassembly mechanism further includes an ejector that is movably inserted through a perforation in the housing, and the housing further includes a cantilever base, with an elastic element connecting the ejector and the cantilever base.

[0010] In some embodiments, the transmission assembly further includes a lever arm fixed between the thrust rod and the turntable.

[0011] In some embodiments, the disassembly mechanism further includes a torsion spring fixed between the turntable and the housing.

[0012] In some embodiments, the rotating member may be a rotating shaft, and the connecting member is formed by extending outward from the radial surface of the rotating shaft. When the operating member drives the rotating member to rotate, it drives the connecting member to push against the latching member, causing the latching member to move from the first position to the second position.

[0013] In some embodiments, the transmission assembly further includes a first force transmission rod connected between the operating member and the rotating member. The first force transmission rod is adapted to abut against the rotating member and to move the latching member between a first position and a second position.

[0014] In some embodiments, the disassembly and assembly mechanism further includes a first elastic element disposed between the housing and the first force transmission rod.

[0015] In some embodiments, the disassembly mechanism further includes an ejector, the housing further includes a through hole, the ejector is disposed in the through hole, and the rotating shaft includes an ejector portion adapted to abut against the ejector.

[0016] In some embodiments, the disassembly and assembly mechanism further includes an ejector and a rotating member, the housing further includes a through hole, the transmission assembly further includes a second force transmission rod, the ejector is disposed through the through hole, the rotating member is adjacent to the ejector, one end of the second force transmission rod is connected to the operating member, the other end of the second force transmission rod is adjacent to the rotating member, and the second force transmission rod is adapted to abut against the rotating member.

[0017] In some embodiments, the transmission assembly further includes a limiting member and a second elastic member, the second elastic member being disposed between the housing and the limiting member, the limiting member contacting the other end of the second force transmission rod, and the limiting member being adapted to be pushed against the second elastic member by the second force transmission rod.

[0018] In some embodiments, the second force transmission rod includes a first guide surface, and the limiting member includes a second guide surface, with the second guide surface correspondingly disposed on the first guide surface.

[0019] In some embodiments, the expansion device is adapted to be combined with an electronic device, the electronic device having a latching part, the housing having a through hole corresponding to the latching part, the latching part being correspondingly disposed in the through hole and a limiting member, the limiting member being adapted to engage with the latching part.

[0020] In some embodiments, a disassembly / assembly mechanism is provided, adapted to a housing, the housing having a latching hole. The disassembly / assembly mechanism includes a transmission assembly and an operating component. The transmission assembly, disposed within the housing, includes a rotating component, a connecting component, and a latching component. The rotating component is pivotally connected to the housing, the connecting component connects the rotating component and the latching component, and a portion of the latching component is exposed within the latching hole. The operating component is disposed within the housing and connected to the transmission assembly. The operating component drives the transmission assembly, causing a portion of the latching component to be movably disposed within the latching hole.

[0021] Accordingly, according to some embodiments, an operating component located in the housing drives a transmission assembly, allowing the latching component to move within the latching holes in the housing. This enables the assembly / disassembly mechanism to perform assembly or disassembly operations, simplifying the process for the user without requiring them to reach into the housing. Therefore, the assembly / disassembly mechanism, through the linkage between the operating component and the transmission assembly, is used to assemble or detach the expansion device from the electronic device.

[0149] Figure 1 This is a schematic diagram illustrating the appearance of the expanded device 100 according to some embodiments. For example... Figure 1 As shown, in some embodiments, the expansion device 100 has a disassembly mechanism 1, through which the expansion device 100 can be assembled to an electronic device for electrical connection, thereby expanding the functionality of the electronic device. The electronic device may be, for example, a thin client, a smartphone, or a tablet computer.

[0150] Following on, such as Figure 1 As shown, for example, in some embodiments, the expansion device 100 is an expansion dock, and the expansion device 100 has a plurality of electrical interfaces C available for expanding the number of electrical interfaces C of the electronic device. In some embodiments, the expansion device 100 may also be a hard disk drive (HDD), optical disc drive, touch panel, or graph card to expand the storage, retrieval, or display functions of the electronic device.

[0151] Figure 2 An exploded view of the expanded device 100 is provided for the purpose of drawing some embodiments. For example... Figure 2 As shown, in some embodiments, the expansion device 100 includes a housing 10. The housing 10 has a snap-fit ​​hole 13. In some embodiments, the expansion device 100 is used in conjunction with a disassembly / removal mechanism 1, which includes a transmission assembly 20 and an operating member 30. The transmission assembly 20 is disposed inside the housing 10 and includes a rotating member 21, a connecting member 22, and a snap-fit ​​member 23. The rotating member 21 is pivotally connected to the housing 10, the connecting member 22 connects the rotating member 21 and the snap-fit ​​member 23, and a portion of the snap-fit ​​member 23 is exposed outside the snap-fit ​​hole 13. The portion of the snap-fit ​​member 23 may be a snap-fit ​​portion 232. The operating member 30 is located outside the housing 10 and is connected to the transmission assembly 20. The operating member 30 drives the transmission assembly 20, causing a portion of the snap-fit ​​member 23 to be movably disposed within the snap-fit ​​hole 13.

[0152] In this way, the user operates the operating member 30 located on the housing 10, which drives the transmission component 20, allowing part of the latch 23 to move within the latch hole 13. This enables the disassembly and assembly mechanism 1 to perform assembly or disassembly operations, thus simplifying the disassembly and assembly process without requiring the user to reach into the housing 10. Therefore, the disassembly and assembly mechanism 1, through the linkage between the operating member 30 and the transmission component 20, is used to assemble or disassemble the expansion device 100 into the electronic device.

[0153] In some embodiments, a portion of the aforementioned fastener 23 may be exposed outside the fastening hole 13. This can be interpreted as the portion of the fastener 23 passing through the fastening hole 13 and moving away from the housing 10, thus the portion of the fastener 23 is located outside the housing 10. For example... Figure 2 and Figure 9 The relationship between the buckle portion 232 of the buckle member 23 and the buckle hole 13 is shown. In some embodiments, a portion of the buckle member 23 is movably disposed within the buckle hole 13. This can be interpreted as a portion of the buckle member 23 passing through the buckle hole 13 and being movable toward the edge of the buckle hole 13, for example... Figure 2 and Figure 5 The relationship between the buckle portion 232 and the buckle hole 13 of the buckle member 23 shown. Figure 3 The drawing is based on some embodiments, with the perspective from bottom to top, for the expansion device 100 (e.g. Figure 2 An exploded view of a partial part (shown). Please refer to [the diagram]. Figures 1 to 3 As shown, in some embodiments, the housing 10 includes a cover 14, a cover 11, a base 12, a receiving hole H1, a through hole 15, a plurality of openings H2, and a first slide rail portion 16.

[0154] Continuing on the above, in some embodiments, the cover 11 is located between the base shell 12 and the cover 14. The cover 11 is correspondingly disposed on the base shell 12, and the cover 14 is fitted over the cover 11. In some embodiments, the cover 11 may be made of metal, and the cover 14 may be made of plastic, so that when the housing 10 is impacted, the impact generated by the cover 11 can be buffered, and the components inside the housing 10 can be protected by the base shell 12.

[0155] In some embodiments, the cover 11 and the base shell 12 of the housing 10 may be different components. Each component may be integrally made of metal material by casting, drawing or stamping, or may be integrally made of plastic by injection molding. Alternatively, each component may be integrally made of plastic and other materials (e.g., metal) by embedded injection molding. In some embodiments, the housing 10 may also be integrally made of a single component.

[0156] As described above, since the structures of the cover 11 and the housing 14 are largely the same in some embodiments, the following description mainly uses the cover 11 as an example. The cover 11 of the housing 10 includes a cover plate 111, a first side plate 112, a second side plate 113, and a third side plate 114. The first side plate 112, the second side plate 113, and the third side plate 114 of the cover 11 extend from three adjacent side edges of the cover plate 111, respectively. The second side plate 113 is connected between the first side plate 112 and the third side plate 114, and the first side plate 112 and the third side plate 114 are disposed opposite to each other. The base shell 12 of the housing 10 includes a base 121 and a fourth side plate 122. The fourth side plate 122 of the base shell 12 extends from one side edge of the base 121. The fourth side plate 122 is connected between the first side plate 112 and the third side plate 114, and the fourth side plate 122 is disposed opposite to the second side plate 113.

[0157] Continuing on the above, the housing 10 may be provided with at least one snap hole 13, which penetrates the cover plate 111 and the cover 14, for at least one snap fastener 23 to use in the at least one snap hole 13. The housing 10 may be provided with at least one through hole 15, which penetrates the cover plate 111 and the cover 14, for at least one ejector 40 to use in the at least one through hole 15.

[0158] In some embodiments, such as Figure 2 As shown, the number of snap holes 13 in the housing 10 can be four, and the number of through holes 15 can be two, but the present invention is not limited thereto. Each snap hole 13 of the housing 10 passes through the cover plate 111 and the casing 14, and each through hole 15 passes through the cover plate 111 and the casing 14, respectively. The four snap holes 13 of the housing 10 include two side-by-side snap holes 13 and two other side-by-side snap holes 13. Two of the snap holes 13 are adjacent to the first side plate 112, and the other two snap holes 13 are adjacent to the third side plate 114. The direction of the two snap holes 13 toward the other two snap holes 13 is equal to the direction of the first side plate 112 toward the third side plate 114 (in this case, opposite to the X-axis direction), and the connection distance between the two snap holes 13 is equal to the connection distance between the other two snap holes 13. One through hole 15 of the housing 10 is adjacent to the first side plate 112 and the fourth side plate 122, and the other through hole 15 is adjacent to the third side plate 114.

[0159] In some embodiments, the buckle hole 13 includes opposing engaging surfaces 131 and disengaging surfaces 132. More specifically, the direction of the engaging surface 131 of the buckle hole 13 adjacent to the first side plate 112 toward the disengaging surface 132 is equal to the direction of the first side plate 112 toward the third side plate 114. The direction of the engaging surface 131 of the buckle hole 13 adjacent to the third side plate 114 toward each disengaging surface 132 is opposite to the direction of the first side plate 112 toward the third side plate 114.

[0160] In some embodiments, the receiving hole H1 of the housing 10 is located on the first side plate 112 and adjacent to the second side plate 113, and extends through the cover 14. In some embodiments, the receiving hole H1 may also be located on the cover plate 111, the second side plate 113, the third side plate 114 or the fourth side plate 122, without limiting the invention thereto.

[0161] In some embodiments, a plurality of openings H2 in the housing 10 are located on the second side plate 113 and penetrate the cover 14, and the plurality of openings H2 are used for the plurality of electrical interfaces C to pass through. In some embodiments, each opening H2 may also be located on the cover plate 111, the first side plate 112, the third side plate 114 or the fourth side plate 122, without limiting the present invention.

[0162] Figure 4 To illustrate the drawing based on some embodiments, for expanding device 100 (e.g.) Figure 2 The partial perspective view shown (without the cover 11 and the casing 14 of the housing 10 removed, retaining a portion of the first pivot member 123 (detailed explanation of the first pivot member 123 will be provided later) and a portion of the first slide rail portion 16. In some embodiments, the housing 10 may be provided with at least one first slide rail portion 16. Figures 3 to 4 As shown, in some embodiments, the number of first slide rail portions 16 of the housing 10 may be two, but the present invention is not limited thereto. Each first slide rail portion 16 is disposed opposite to each other on the cover plate 111, and as... Figures 3 to 4 As shown, the first slide rail portion 16 is adjacent to the first side plate 112, and the other first slide rail portion 16 is adjacent to the third side plate 114.

[0163] like Figures 2 to 4 As shown, in some embodiments, the cover plate 111 of the housing 10 is fixedly provided with a first pivot member 123. The axial direction of the first pivot member 123 is from the cover plate 111 toward the base 121 (i.e., opposite to the Z-axis direction). The first pivot member 123 may be located between a plurality of first slide rail portions 16. In other words, each first slide rail portion 16 is located on opposite sides of the first pivot member 123. In some embodiments, the first pivot member 123 may also be fixed to the base 121, or the first pivot member 123 may also be fixed between the base 121 and the cover plate 111.

[0164] In some embodiments, the transmission assembly 20 of the disassembly and assembly mechanism 1 is disposed within the housing 10, and the transmission assembly 20 includes a push rod 24. The push rod 24 is connected between the operating member 30 and the rotating member 21. The operating member drives the push rod 24, so that the push rod 24 can drive the rotating member 21 to rotate, and the rotating member 21 drives the latching member 23 to move between a first position and a second position through the linkage 22 (the positional states of the first position and the second position will be described later). The push rod 24 is connected to the rotating member 21. The connection includes direct connection and indirect connection. The connection relationship of each component of the transmission assembly 20 is described in detail below.

[0165] In some embodiments, the rotating member 21 may be made of plastic or metal, and the rotating member 21 may be a turntable. The rotating member 21 includes a first pivot 211 and a second pivot 212. The first pivot 211 is located at the center of the rotating member 21, and the second pivot 212 is adjacent to the outer edge of the rotating member 21.

[0166] In some embodiments, the first pivot point 211 of the rotating member 21 is a pivot hole, and the first pivot member 123 of the housing 10 is a pivot shaft. The first pivot point 211 of the rotating member 21 is pivotally mounted on the first pivot member 123 of the housing 10, so the rotating member 21 can rotate relative to the housing 10 along the axial direction of the first pivot member 123 (i.e., opposite to the Z-axis direction). In some embodiments, the first pivot point 211 may also be a pivot shaft, and the first pivot member 123 may also be a pivot hole, without limiting the invention thereto.

[0167] In some embodiments, the disassembly and assembly mechanism 1 further includes a torsion spring 50, one end of which is fixed to the first pivot member 123, and the other two ends of the torsion spring 50 are respectively fixed to the outer edge of the rotating member 21.

[0168] Figure 5 Based on some embodiments, the disassembly and assembly mechanism 1 (e.g.) Figure 1 A partial sectional view (shown) shows the latch 23 in its inactive state. Figures 4 to 5 As shown, each latching member 23 of the transmission assembly 20 may include a latch 231, a second slide rail portion 233, and a base 234. The latch 231 of the latching member 23 has a latching portion 232 at its end, which extends from the end of the latch 231 toward the engaging surface 131 of the latching hole 13. The latch 231 passes through the latching hole 13, and the latching portion 232 at the end of the latch 231 passes through the latching hole 13 and protrudes outside the latching hole 13, as shown... Figure 5 As shown, the latch 232 maintains a gap with the cover plate 111 of the housing 10 to accommodate and engage the housing of the electronic device. In some embodiments, the latch 23 may be provided with two latches 231, which are arranged side by side on the base 234, but the present invention is not limited thereto.

[0169] Figure 6 Based on some embodiments, the disassembly and assembly mechanism 1 (e.g.) Figure 1 Another partial cross-sectional view (shown). Figure 7 Based on some embodiments, the disassembly and assembly mechanism 1 (e.g.) Figure 1 (As shown) is a top-down view before the activity. For ease of illustration, [the diagram is missing]. Figure 7 The boundary of the middle casing 10 is only indicated by dashed lines. Continuing from above, as... Figure 7 As shown, the fastener 23 is provided with a second slide rail portion 233, which is disposed on the base 234 and adjacent to the fastener 231 (please refer to the diagram). Figure 4 ).like Figure 7 As shown, the second slide rail portion 233 has opposing first limiting portions B1 and second limiting portions B2, and a slide rail direction D1, where the slide rail direction D1 is the direction in which the latching member 23 faces the rotating member 21. In some embodiments, the first slide rail portion 16 may be a protruding post, and the first slide rail portion 16 may be disposed on the second slide rail portion 233, so that the latching member 23 is movably disposed on the housing 10 along the slide rail direction D1, and the first slide rail portion 16 is limited between the first limiting portion B1 and the second limiting portion B2.

[0170] In some embodiments, the second slide rail portion 233 of the latching member 23 may include two parallel elongated straight through holes, respectively adjacent to the second side plate 113 and the fourth side plate 122. The first slide rail portion 16 may include two parallel protrusions, respectively adjacent to the second side plate 113 and the fourth side plate 122. The second slide rail portion 233 is correspondingly disposed on the first slide rail portion 16. In some embodiments, the second slide rail portion 233 may also be a protrusion, and the first slide rail portion 16 may also be a through hole or a groove, without limiting the present invention.

[0171] In some embodiments, the transmission assembly 20 may include at least one latching member 23 and at least one linkage member 22, such as Figure 2 As shown, the transmission assembly 20 is provided with two latching members 23 and two connecting members 22 (the number of latching members 23 and connecting members 22 is two in this case, but the invention is not limited thereto), and the connecting members 22 are symmetrically arranged on both sides of the rotating member 21. The latching members 23 are adjacent to the first side plate 112 relative to the other latching member 23. Each latching member 23 is provided with a second slide rail portion 233, and each second slide rail portion 233 cooperates with each first slide rail portion 16, so that the latching member 23 is slidably disposed on the housing 10.

[0172] Please refer to Figures 2 to 7The linkage 22 of the transmission assembly 20 can be a link. The linkage 22 may include a first link end 221, a second link end 222, and a linkage direction D3. The first link end 221 of the linkage 22 can be pivotally connected to the base 234 of the latching member 23, and the second link end 222 can be pivotally connected to the second pivot point 212 of the rotating member 21. The linkage direction D3 of the linkage 22 is from the first link end 221 toward the second link end 222. There is an angle θ1 between the linkage direction D3 and the slide rail direction D1. The linkage direction D3 needs to be rotated about the second pivot point 212 as the axis along an axial direction opposite to the first pivot member 123 to coincide with the slide rail direction D1. The angle θ1 is, for example, 15 degrees, 30 degrees, or 45 degrees.

[0173] In some embodiments, the lever arm 25 may include a first lever arm end 251, a second lever arm end 252, and a lever arm direction D5. The first lever arm end 251 may be fixed to the side edge of the rotating member 21, and the lever arm direction D5 is the direction in which the first lever arm end 251 faces the second lever arm end 252.

[0174] In some embodiments, the thrust rod 24 may include a first thrust rod end 241, a second thrust rod end 242, and a thrust direction D6. The second thrust rod end 242 of the thrust rod 24 may be pivotally connected to the first lever arm end 251 of the lever arm 25. The thrust direction D6 is the direction from the first thrust rod end 241 to the second thrust rod end 242, and there is an angle ω1 between the thrust direction D6 and the lever arm direction D5. The thrust rod 24 is indirectly connected to the rotating member 21 through the lever arm 25. In some embodiments, the thrust rod 24 of the transmission assembly 20 may also be directly connected to the rotating member 21 without the need for connection through the lever arm 25, depending on the specific application requirements.

[0175] In some embodiments, the operating member 30 of the disassembly and assembly mechanism 1 is located outside the housing 10 and is correspondingly disposed in the receiving hole H1 of the housing 10. In some embodiments, the operating member 30 includes an operating part 31 and a connecting part 32, with the connecting part 32 extending from the operating part 31. The area of ​​the operating part 31 is larger than the area of ​​the receiving hole H1 of the housing 10, and the area of ​​the receiving hole H1 is larger than the area of ​​the connecting part 32. Therefore, the connecting part 32 can pass through the receiving hole H1 and connect to the outside, so that the operating part 31 is located outside the housing 10. The connecting part 32 of the operating member 30 is fixedly connected to the first thrust rod end 241 of the thrust rod 24. Furthermore, as with the aforementioned connection relationship between the thrust rod 24, the rotating member 21, the linkage member 22, and the latching member 23, the operating member 30 can actuate the transmission assembly 20.

[0176] In some embodiments, the disassembly mechanism 1 further includes an ejector 40, which, for reference, is described below. Figure 2 and Figure 6The ejector 40 includes a limiting block 42 and opposing ejector surfaces 41 and base surfaces 43. The ejector surfaces 41 pass through each through hole 15, and the limiting block 42 is located between the ejector surfaces 41 and the base surface 43. The area of ​​the limiting block 42 is larger than the area of ​​each cross section from the ejector surfaces 41 to the limiting block 42 in the ejector 40. In some embodiments, a cantilever seat J is fixed to the cover plate 111 adjacent to the through hole 15. An elastic element 70 is provided on each cantilever seat J, and the base surface 43 is located at one end of the elastic element 70. The elastic element 70 abuts against the ejector 40 and provides the ejector 40 with a deformation capacity, allowing the ejector 40 to protrude from the through hole 15.

[0177] The following explains the linkage relationship between the operating component 30 and the transmission assembly 20. Figure 8 Based on some embodiments, the disassembly and assembly mechanism 1 (e.g.) Figure 1 (See diagram) Top view of the activity. Figure 9 Based on some embodiments, the disassembly and assembly mechanism 1 (e.g.) Figure 1 The diagram shows a partial sectional view (as shown) illustrating the movable state of the fastener 23. Please refer to the diagram for further details. Figures 2 to 9 When the electronic device is combined with the expansion device 100, the operating member 30 is in an initial position, and the operating part 31 of the operating member 30 is located at the position furthest from the receiving hole H1. Meanwhile, please also refer to... Figure 2 and Figure 5 The fastener 23 is in the first position, at which time the fastening part 232 of the fastener 23 approaches the engaging surface 131 of the fastening hole 13 (e.g., Figure 5 The upper surface of the cover 14 is fastened by the buckle 232 shown. The projection of the buckle 232 of the buckle member 23 toward the buckle hole 13 (in this case, opposite to the z direction) falls on the cover 14, so that the disassembly and assembly mechanism 1 can fasten the outer shell of the electronic device between the buckle 232 and the housing 10, and then fasten the expansion device 100 to the electronic device.

[0178] Simultaneously, the second limiting portion B2 of the second slide rail portion 233 abuts against the first slide rail portion 16. In some embodiments, when the latching member 23 is in the first position, the second limiting portion B2 of the second slide rail portion 233 and the first slide rail portion 16 may also maintain a gap, so that the latching portion 232 of each latching member 23 has enough space to move and abut against the engaging surface 131 of each latching hole 13. In some embodiments, since the ejector 40 is connected to each cantilever seat J by an elastic member 70, when the latching member 23 is in the first position and the expansion device 100 is fastened to the electronic device, the ejector 40 will be pushed by the electronic device and move towards the cantilever seat J, thereby squeezing each elastic member 70 and causing the elastic member 70 to accumulate deformation energy.

[0179] When the user wants to separate the expansion device 100 from the electronic device, after applying an operating force to the operating part 31, the operating member 30 will move from its initial position toward the receiving hole H1. The thrust rod 24, which is fixed to the operating member 30, will be driven by the operating member 30 to move in the thrust direction D6 and generate a thrust along the thrust direction D6. Since the rotating member 21 and the thrust rod 24 are connected by the lever arm 25, the lever arm 25 will convert the thrust transmitted from the thrust rod 24 into a tangential force of the rotating member 21, causing the rotating member 21 to generate torque and rotate along an axis opposite to that of the first pivot member 123. In addition, since the lever arm 25 increases the distance between the first pivot member 123 of the rotating member 21 and the point of force application, it can amplify the torque generated by the rotating member 21.

[0180] In some embodiments, since the angle ω1 between the thrust direction D6 of the thrust rod 24 and the lever arm direction D5 (in this case, in the same direction as the y-axis) of the lever arm 25 is 90 degrees, and the connection of the lever arm direction D5 is through the first pivot 211 of the rotating member 21, the lever arm 25 can completely convert the thrust into a tangential force, thereby improving the efficiency of the operating force applied to the operating member 30. In some embodiments, the angle between the thrust direction D6 of the thrust rod 24 and the lever arm direction D5 of the lever arm 25 can also be 60 degrees or 75 degrees, depending on the application requirements.

[0181] Since the first link end 221 and the second link end 222 of the linkage 22 are respectively connected to the latching member 23 and the rotating member 21, when the rotating member 21 rotates along an axis opposite to that of the first pivot member 123, the latching member 23 will be driven by the linkage 22 to generate a pulling force component toward the rotating member 21 and move away from the first position. Furthermore, since the movement direction of the latching member 23 is limited by the first slide rail portion 16 and the second slide rail portion 233, the latching member 23 is restricted to linear motion relative to the housing 10 along the slide rail direction D1 and to move toward the rotating member 21. During the above linkage process, such as... Figure 5 and Figure 9 As shown, the buckle 231 of the buckle 23 gradually moves away from the engaging surface 131, and the first limiting part B1 of the second slide rail 233 moves toward the first slide rail 16.

[0182] Continuing on, when the operating force is continuously applied to the operating member 30, when the operating part 31 of the operating member 30 is located closest to the receiving hole H1, the operating member 30 is in the operating position. In the operating position, the angle ω2 between the thrust direction D6 and the lever arm direction D5 of the lever arm 25 will be smaller than the angle ω1 in the initial position (please refer to the reference). Figure 7 In the operating position, the angle θ2 between the linkage direction D3 and the slide rail direction D1 will be greater than the angle θ1 in the initial position (please refer to the reference). Figure 7 At this point, the fastener 23 moves away from the first position and to the second position (e.g., the fastener 23 is moved by...). Figure 5 The first position is moved to Figure 9 (Second position). When the latching member 23 is in the second position, the second limiting portion B2 of the second slide rail portion 233 is adjacent to the first slide rail portion 16, and the latching portion 232 of the latching member 23 is away from the engaging surface 131 and the housing of the electronic device, causing the expansion device 100 to be unfastened to the electronic device. At the same time, the elastic member 70 gradually releases deformation energy, thereby pushing the ejector 40 toward the through hole 15 and pushing the electronic device away from the expansion device 100. In addition, since the limiting block 42 is confined within the through hole 15 of the housing 10, the ejector 40 will not detach from the housing 10 through the through hole 15 during the above-mentioned activities.

[0183] Following on, such as Figure 7 and Figure 8 As shown, when the operating force applied to the operating member 30 is released, since the rotating member 21 is no longer subjected to the operating force, the torsion spring 50 will release the deformation energy accumulated in the above process, thereby causing the rotating member 21 to rotate along the axial direction of the first pivot member 123. Therefore, the rotating member 21, in conjunction with the latching member 23, returns from the second position to the first position (please refer to...). Figure 5 and Figure 9 ), and the operating component 30 is moved from the operating position back to the initial position.

[0184] In some embodiments, such as Figure 2 As shown, the disassembly and assembly mechanism 1 further includes an electrical connector 60, which is exposed outside the housing 10. This allows the disassembly and assembly mechanism 1 to directly connect to an electronic device, thereby expanding the functionality of the device 100 by enabling electrical connection with electronic devices. In some embodiments, the electrical connector 60 may be disposed adjacent to the latching member 23, but this is not a limitation.

[0185] Figure 10 This is a schematic diagram illustrating the assembly of the expansion device 100” and the electronic device 200” according to some embodiments. Figure 11 The diagram is an exploded view of an expansion device 100” and an electronic device 200” according to some embodiments. In some embodiments, the expansion device 100” and the electronic device 200” are two display panels, and the expansion device 100” can be assembled or detached from the electronic device 200” through the disassembly mechanism 1” on the expansion device 100” and the assembly hole 202” on the electronic device 200”.

[0186] Figure 12 This is a schematic diagram illustrating the assembly of the expansion device 100' and the electronic device 200' according to some embodiments.

Figure 13 As shown, in some embodiments, the disassembly and assembly mechanism 1' includes a housing 10', a transmission assembly 20', and an operating component 30'.

[0187] like Figure 13 As shown, in some embodiments, the housing 10' of the disassembly and assembly mechanism 1' includes a cover 11', a base shell 12', and a cover 14'. The cover 11' is located between the base shell 12' and the cover 14'. The cover 11' is correspondingly disposed on the base shell 12', and the cover 14' is fitted onto the cover 11'.

[0188] like Figure 13 As shown, in some embodiments, the cover plate 111' of the shell cover 11' is provided with a first groove E1', a second groove E2', and a third groove E3'. The first groove E1', the second groove E2', and the third groove E3' are all formed by the cover plate 111' being recessed towards the base shell 12', forming an accommodating space with the cover shell 14'. The first groove E1' is adjacent to the first side plate 112' and the second side plate 113'. The second groove E2' is adjacent to the first side plate 112' and the fourth side plate 122'. The third groove E3' is adjacent to the third side plate 114', and the third groove E3' is located in the middle position between the second side plate 113' and the fourth side plate 122'. However, the positions of the grooves are not limited to this.

Figure 12 An exploded view of a partial part (shown). Figure 15 For drawing Figure 13 The L-shaped guide line provides a view for expanding the device 100' and the electronic device 200' (e.g., ...). Figure 12 An exploded view of a partial part (as shown). Figure 13 and Figure 15As shown above, the cover plate 111' of the shell cover 11' is provided with a first guide rail portion 16', a first pivot portion 17', a third guide rail portion 18', a fifth guide rail portion 19', and a limiting hole H3'. The first guide rail portion 16' is adjacent to the first groove E1' and the second side plate 113'. The first pivot portion 17' is adjacent to the second groove E2' and the fourth side plate 122'. The direction of the first guide rail portion 16' toward the first pivot portion 17' is equal to the direction of the second side plate 113' toward the fourth side plate 122' (in this case, opposite to the Y-axis). The third guide rail portion 18' is adjacent to the third groove E3', and the third guide rail portion 18' is farther away from the third side plate 114' than the third groove E3'. The fifth guide rail portion 19' is adjacent to the third guide rail portion 18', and the fifth guide rail portion 19' is closer to the third side plate 114' and the fourth side plate 122' than the third guide rail portion 18'. The limiting hole H3' is adjacent to the third guide rail section 18'.

[0190] like Figures 13 to 14 As shown, the cover 14' has snap holes 13', through holes 15', and through holes H4'. In some embodiments, the cover 14' has two snap holes 13' and four through holes 15', two of which are correspondingly disposed in the first groove E1', and the two through holes 15' are arranged between the two snap holes 13', and are arranged sequentially from the first side plate 112' toward the third side plate 114'. The connection direction of the two snap holes 13' and the two through holes 15' is equal to the connection direction of the first guide rail portion 16' and the first pivot portion 17' (which is opposite to the Y-axis direction in this case). One through hole 15' corresponds to the second groove E2', so that the through hole 15' and the bottom of the groove of the second groove E2' form an accommodating space. The other through hole 15' corresponds to the third groove E3', so that the through hole 15' and the bottom of the groove of the third groove E3' form an accommodating space. The through hole H4' corresponds to the limiting hole H3'. The engagement surface 131' and the unengaging surface 132' of the buckle hole 13' are configured the same as those of the engagement surface 131 and the unengaging surface 132 of the buckle hole 13, and will not be described again here.

[0191] like Figures 13 to 15 As shown, in some embodiments, the housing 14' is provided with a second pivot 123A' and a third pivot 123B'. The second pivot 123A' is disposed on the side of the housing 14' facing the cover 11', and is located between the connection between the snap hole 13' and the through hole 15' and the connection between the first guide rail portion 16' and the first pivot portion 17'. The axial direction of the second pivot 123A' is equal to the direction of the first guide rail portion 16' toward the first pivot portion 17' (in this case, opposite to the Y-axis direction). The third pivot 123B' is disposed on the housing 14', and the axial direction of the third pivot 123B' is equal to the direction from the fourth side plate 122' toward the second side plate 113' (in this case, the same as the Y-axis direction), and the third pivot 123B' is adjacent to the through hole 15'.

[0192] like Figures 12 to 14 As shown, in some embodiments, the transmission assembly 20' includes a rotating member 21', a connecting member 22', a locking member 23', a thrust rod 24', a first force transmission rod 25', and a second force transmission rod 26'.

The thrust rod 24' is connected to the first force transmission rod 25', and the first force transmission rod 25' is connected to the second force transmission rod 26'. The thrust rod 24' can drive the first force transmission rod 25' to push against the rotating member 21', causing the rotating member 21' to move the locking member 23' between a first position and a second position via the connecting member 22'. The first force transmission rod 25' can also drive the second force transmission rod 26' to move. The connection includes direct and indirect connections; the connection relationships of the various components of the transmission assembly 20' are described in detail below. The relative relationship between the latching member 23' and the latching hole 13' in the first and second positions is the same as the aforementioned relative relationship between the latching member 23 and the latching hole 13 in the first and second positions. The latching member 23' in the first position allows the expansion device to be fastened to the electronic device, and the latching member 23' in the second position allows the expansion device to be unfastened to the electronic device. These details will not be repeated here.

[0193] In some embodiments, the rotating member 21' of the transmission assembly 20' may be a rotating shaft, with one end of the rotating member 21' adjacent to the second side plate 113' and the other end adjacent to the fourth side plate 122'. For example... Figure 12 As shown, the second pivot member 123A' includes multiple partitions, each partition having a pivot hole. The rotating member 21' is coaxial with the second pivot member 123A'. The rotating member 21' is pivotally mounted on the second pivot member 123A' of the cover 14', and the rotating member 21' can rotate along the axial direction of the second pivot member 123A' (in this case, the direction opposite to the Y-axis).

[0194] Following on, such as Figure 14As shown, the rotating member 21' includes an ejector portion 21A' extending from the side edge of the rotating member 21' and adjacent to the through hole 15'. In some embodiments, the rotating member 21' may include three ejector portions 21A' arranged side-by-side along the axial direction of the rotating member 21'. The linkage 22' of the transmission assembly 20' is formed by extending outward from the side edge of the rotating member 21' (shaft), which may be the radial surface of the shaft. In some embodiments, the linkage 22' includes two protrusions 22A' arranged side-by-side, arranged side-by-side along the axial direction of the rotating member 21'. The linkage 22' and the rotating member 21' may be integrally formed or spliced ​​together.

Figure 17 For drawing Figure 16 The AA guide line view is for the disassembly and assembly mechanism 1' and electronic device 200' (e.g. Figure 12 A partial sectional view (shown) shows the state of the disassembly / assembly mechanism before it is activated. Figure 17 As shown, the fastening member 23' includes a fastener 231', a fastening portion 232', a return member 233', and a fixing base 234'.

When the buckle 231' moves in an unlocking direction, maintaining a gap between the buckle 231' and the engaging surface 131', the expansion device 100' can be released from the electronic device 200'. The unlocking direction can be away from the engaging surface 131' or towards the release surface 132'. In some embodiments, the return member 233' is a spring, disposed between the buckle 231' and the fixing base 234'.

[0196] like Figure 13 and Figure 16As shown, in some embodiments, the first force transmission rod 25' includes a first force transmission portion 251' and a second force transmission portion 252' respectively disposed at both ends of the first force transmission rod 25', and is provided with a second guide rail portion 253' and a second pivot portion 254'.

[0199] In some embodiments, the disassembly / assembly mechanism 1' may be provided with a first elastic element 70'.

[0200] In some embodiments, the second force transmission rod 26' is provided with a third force transmission portion 261' and a fourth force transmission portion 262'.

The first guide surface 264', the first contact surface 265', and the pushing surface 266' are provided at the periphery of the fourth force transmission portion 262'. The first guide surface 264' is connected between the first contact surface 265' and the pushing surface 266'. The pushing surface 266' is provided on the side of the fourth force transmission portion 262' facing the third side plate 114'.

The third guide rail portion 18' can be restricted to move between the third limiting portions I3' and the fourth limiting portions I4' of the fourth guide rail portion 263'. In some embodiments, the third guide rail portion 18' includes two side-by-side protrusions, and the fourth guide rail portion 263' includes two side-by-side linear elongated through holes, thus the third guide rail portion 18' is restricted to linear movement between the third limiting portions I3' and the fourth limiting portions I4' of the fourth guide rail portion 263'.

[0201] Please refer to Figures 13 to 16In some embodiments, the transmission assembly 20' may further include a limiting member 90' and a second elastic member 71'. The limiting member 90' of the transmission assembly 20' includes a second guide surface 91', a second contact surface 92', a limiting hole 93', and a sixth guide rail portion 94'. The second guide surface 91' and the second contact surface 92' are connected and disposed at the periphery of the limiting member 90', and the second guide surface 91' and the second contact surface 92' can contact the first guide surface 264' and the first contact surface 265', respectively.

In some embodiments, the fifth guide rail portion 19' includes two parallel protrusions, and the sixth guide rail portion 94' includes two parallel linear elongated through holes, thus the fifth guide rail portion 19' is restricted to linear movement between the fifth limiting portion I5' and the sixth limiting portion I6' of the sixth guide rail portion 94'. One end of the second elastic member 71' is fixed to a side edge of the limiting member 90' away from the second contact surface 92', and the other end of the second elastic member 71' is fixed to the cover 11'.

[0202] Figure 20 For drawing Figure 16 The GG guide line view shows the disassembly mechanism 1' and electronic device 200' (e.g., Figure 12 A partial sectional view (shown) shows the state of the disassembly / assembly mechanism before it is activated. Figure 16 As shown, in some embodiments, the limiting hole 93' has opposing first limiting hole end 931' and second limiting hole end 932', the second limiting hole end 932' being closer to the second contact surface 92' than the first limiting hole end 931'. In some embodiments, the limiting hole 93' is adapted to engage with a latching portion 203' of the electronic device 200' via the first limiting hole end 931'. The second elastic member 71' is adapted to provide the limiting member 90' with a deformation energy, causing the limiting member 90' to engage or disengage from the latching portion 203'.

[0203] Figure 18 For drawing Figure 16 The BB guide line view is for the disassembly and assembly mechanism 1' and electronic device 200' (e.g. Figure 12 A partial cross-sectional view (shown) showing the state of the disassembly and assembly mechanism before it is activated. Figure 19 For drawing Figure 16 The FF guide line view is for the disassembly mechanism 1' and electronic device 200' (e.g., Figure 12The diagram shows a partial cross-sectional view of the disassembly / assembly mechanism before its operation. Please refer to the diagram. Figure 13 , Figure 14 and Figure 18 , Figure 19 In some embodiments, the disassembly / assembly mechanism 1' includes an ejector 40', which includes a limiting block 42' and opposing ejector surfaces 41' and base surfaces 43'. The base surface 43' is adjacent to the bottom of the groove relative to the ejector surface 41'. The limiting block 42' is located between the ejector surface 41' and the base surface 43', and the area of ​​the limiting block 42' is larger than the area of ​​the through hole 15'. The area of ​​the through hole 15' is larger than the area of ​​each cross section from the ejector surface 41' to the limiting block 42' in the ejector 40', so that the ejector 40' can be inserted through the through hole 15' without falling off the expansion device 100'. In some embodiments, each ejector 40' is accommodated in the receiving space formed by the bottom of the through hole 15' and the first groove E1', another ejector 40' is accommodated in the receiving space formed by the bottom of the through hole 15' and the second groove E2', and another ejector 40' is accommodated in the receiving space formed by the bottom of the through hole 15' and the third groove E3'.

[0204] like Figure 14 and Figure 16 As shown, in some embodiments, the disassembly and assembly mechanism 1' may be provided with a rotating member 80', which is pivotally mounted on the third pivot member 123B' of the housing 10', and the rotating member 80' is disposed between the fourth force transmission part 262' of the second force transmission rod 26' and one of the ejector members 40'.

[0205] In some embodiments, such as Figure 13 and Figure 16 The operating component 30' of the disassembly and assembly mechanism 1' shown is located outside the housing 10 and is correspondingly disposed in the receiving hole H1' of the housing 10'. The operating component 30' is connected to the first thrust rod end 241' of the thrust rod 24'. Furthermore, similar to the connection relationship between the thrust rod 24', the first transmission rod 25', the second transmission rod 26', the rotating component 21', the linkage component 22', and the latching component 23', when the operating component 30' is pushed, the transmission assembly 20' can be moved in conjunction. The configuration of the operating component 30' is the same as that of the operating component 30, and will not be described in detail here.

[0206] Figure 21 To illustrate the drawing based on some embodiments, the expansion device 100' (e.g.) Figure 12 The top view shown is shown in the figure, with some parts omitted. The boundary of the housing 10' is indicated by dashed lines. This is the state when the operating component 30' is not pressed. In this state, the operating component 30' is in the initial position. Figure 22 To illustrate the drawing based on some embodiments, the expansion device 100' (e.g.) Figure 12Another top view (shown below), omitting some parts, shows the housing 10' with its boundary indicated by dashed lines, indicating the state when the operating element 30' is pressed down. In this state, the operating element 30' is in the operating position. Please refer to the diagram below. Figures 13 to 22 As shown, when the user wishes to separate the expansion device 100' from the electronic device 200', they can press the operating member 30' to move the operating member 30' from the initial position to the operating position. The following explains the linkage relationship between the operating member 30' and the transmission assembly 20'.

[0207] like Figure 21 As shown, when the operating member 30' is in its initial state, the operating part 31' of the operating member 30' is located at the position furthest from the receiving hole H1' of the housing 10'. The ejector part 21A' of the rotating member 21' is away from the three ejector parts 40' and the protrusion 22A' is away from the fastener 231' of the latching member 23', at which time the latching member 23' is in the first position. The rotating member 80' is away from the other ejector part 40'. At this time, the first guide rail part 16' abuts against the second limiting part I2' of the second guide rail part 253' of the first force transmission rod 25'. The third guide rail part 18' abuts against the fourth limiting part I4' of the fourth guide rail part 263' of the second force transmission rod 26', and the fifth guide rail part 19' abuts against the sixth limiting part I6' of the sixth guide rail part 94' of the limiting member 90'. The second guide surface 91' of the limiting member 90' contacts the first guide surface 264' of the second force transmission rod 26', and the first limiting hole end 931' of the limiting member 90' is engaged with the latching part 203' of the electronic device 200' (see reference). Figure 16 The fourth force transmission part 262' of the second force transmission rod 26' is away from the rotating part 80'.

[0208] like Figure 21 and Figure 22 As shown, when the user applies an operating force to the operating part 31', the operating member 30' will move toward the receiving hole H1', ​​and the thrust rod 24' fixed to the operating member 30' will be driven by the operating member 30' to move in the thrust direction D6', and generate a thrust along the thrust direction D6'.

[0209] like Figures 13 to 22 As shown, since the first force transmission part 251' of the first force transmission rod 25' is connected to the second thrust rod end 242' of the thrust rod 24' and the first force transmission rod 25' is pivotally connected to the first pivot part 17' of the cover 11' via the second pivot part 254', the first force transmission rod 25' converts the thrust transmitted from the thrust rod 24' into torque, causing the first force transmission rod 25' to rotate around the first pivot part 17' as an axis. The second force transmission part 252' of the first force transmission rod 25' contacts and pushes against the rotating member 21', and the first elastic member 70' adjacent to the first force transmission part 251' accumulates deformation energy. Simultaneously, the first limiting part I1' of the second guide rail part 253' moves towards the first guide rail part 16'.

[0210] Figure 23 For drawing Figure 16 The AA guide line view is for the disassembly and assembly mechanism 1' and electronic device 200' (e.g. Figure 12 A partial cross-sectional view (shown) shows the state of the disassembly and assembly mechanism during operation. Figure 24 For drawing Figure 16 The BB guide line view is for the disassembly and assembly mechanism 1' and electronic device 200' (e.g. Figure 12 A partial sectional view (as shown) illustrates the state of the disassembly / assembly mechanism during operation. Figures 16 to 24 When the rotating member 21' receives the thrust from the second force transmission part 252', it generates torque, causing the rotating member 21' to rotate along the axial direction of the second pivot member 123A'. The linkage member 22' connected to the rotating member 21' rotates toward the fastener 231' of the latching member 23', thereby pushing the fastener 231' and pushing it toward the fixed seat 234'. As a result, the return member 233' is compressed and deformed. At the same time, the ejector part 21A' of the rotating member 21' rotates toward the base surface 43' of the ejector member 40', thereby pushing the base surface 43' so that the ejector member 40' can protrude out of the through hole 15' and push against the outer casing 201' of the electronic device 200', thereby separating the electronic device 200' from the expansion device 100'.

[0211] Figure 25 For drawing Figure 16 The FF guide line view is for the disassembly mechanism 1' and electronic device 200' (e.g., Figure 12 A partial cross-sectional view (shown) shows the state of the disassembly and assembly mechanism during operation. Figure 26 For drawing Figure 16 The GG guide line view shows the disassembly mechanism 1' and electronic device 200' (e.g., Figure 12 A partial sectional view (as shown) illustrates the state of the disassembly / assembly mechanism during operation. Figures 16 to 26As shown, since the third force transmission part 261' of the second force transmission rod 26' is connected to the push rod 24' through the first force transmission rod 25', when the push rod 24' is moved by the operating force, it drives the second force transmission rod 26' to move. At this time, the fourth force transmission part 262' moves toward the rotating member 80', and the pushing surface 266' of the fourth force transmission part 262' pushes against the rotating member 80', so that the rotating member 80' can rotate along the axial direction of the third pivot member 123B', and then pushes against the ejector member 40', so that the ejector member 40' can protrude out of the through hole 15' and push against the outer casing 201' of the electronic device 200'. Simultaneously, the first guide surface 264' of the second force transmission rod 26' guides the second guide surface 91' of the limiting member 90', causing the first contact surface 265' to contact the second contact surface 92', thereby driving the fifth limiting part I5' of the sixth guide rail part 94' of the limiting member 90' to move towards the fifth guide rail part 19', causing the limiting member 90' to compress the second elastic member 71' and generate deformation energy. At this time, the first limiting hole end 931' of the limiting hole 93' moves away from the latching part 203' of the electronic device 200'.

[0212] like Figure 22 As shown, an operating force is continuously applied to the operating member 30'. When the operating part 31' of the operating member 30' is located at the position closest to the receiving hole H1' of the housing 10', the operating member 30' is in the operating position. In this case, please refer to... Figures 16 to 23 The push rod 24' drives the rotating member 21' to move the locking member 23', which moves between a first position and a second position (e.g., the locking member 23' is moved by...). Figure 17 The first position is moved to Figure 23 (The second position). At this time, the first limiting part I1' of the second guide rail 253' abuts against the first guide rail 16', the third limiting part I3' of the fourth guide rail 263' abuts against the third guide rail 18', and the fifth limiting part I5' of the sixth guide rail 94' abuts against the fifth guide rail 19'. Figure 23 and Figure 26 As shown, when the buckle 23' is in the second position, a gap is maintained between the buckle 231' and the engaging surface 131' of the buckle 23'. This gap is formed by the buckle 231' moving in the unlocking direction (e.g., the buckle 231' facing towards...). Figure 23 The movement to the left causes the latch 232' to unfasten to the housing 201' of the electronic device 200' (as shown in the image). Figure 23 The buckle 232' shown is separated from the upper surface of the housing 201', so that the housing 201' and the buckle 232' do not contact each other, and a gap is also maintained between the latching part 203' of the electronic device 200' and the limiting member 90', thereby allowing the electronic device 200' to be detached from the disassembly and assembly mechanism 1'. Meanwhile, as Figure 24As shown, the ejector surface 41' of the ejector 40' pushes against the housing 201' of the electronic device 200', thereby causing the housing 201' to disengage from the latching portion 232' of the latching member 23'. Furthermore, since the area of ​​the limiting block 42' of the ejector 40' is larger than the area of ​​the through hole 15', the limiting block 42' can be confined within the through hole 15' of the housing 10', preventing the ejector 40' from disengaging from the housing 10' through the through hole 15' during the aforementioned activities.

[0213] Following on from above, please compare them together. Figures 16 to 26 When the operating force applied to the operating member 30' is released, the first elastic member 70', the second elastic member 71', and the return member 233' release the deformation energy accumulated during the above process, thereby causing the latching member 23' to return from the second position to the first position, and causing the first guide rail portion 16' to abut against the second limiting portion I2' of the second guide rail portion 253' of the first force transmission rod 25'. The third guide rail portion 18' abuts against the fourth limiting portion I4' of the fourth guide rail portion 263' of the second force transmission rod 26', and the fifth guide rail portion 19' abuts against the sixth limiting portion I6' of the sixth guide rail portion 94' of the limiting member 90'. The second guide surface 91' of the limiting member 90' contacts the first guide surface 264' of the second force transmission rod 26', and the operating member 30' returns from the operating position to the initial position.

[0214] In summary, according to some embodiments, the disassembly and assembly mechanism switches the operating component outside the housing to the initial or operating position. This causes the operating component to drive the push rod of the transmission assembly, which in turn drives the rotating component, which in turn drives the linkage component, and the linkage component drives the latching component. This positions the push rod and the latching component in a first or second position, enabling the disassembly and assembly mechanism to perform assembly or disassembly operations. Therefore, users can perform these operations without having to reach into the housing, simplifying the assembly and disassembly process. Furthermore, the disassembly and assembly mechanism can assemble expansion devices into the housing of electronic devices, eliminating the need for additional space to accommodate electronic equipment. This facilitates the thinning, miniaturization, and weight reduction of electronic devices.
