snap mechanism

Abstract

A buckle mechanism includes a housing, a first buckle member and a second buckle member. The housing has a first clamping groove and a second clamping groove. The first buckle member is slidably arranged in the housing and has a first clamping portion. The second buckle member is rotatably arranged in the housing and has a second clamping portion. When the first buckle member is in a first locking position, the second buckle member is rotatable between a second locking position and a second unlocking position. When the second buckle member is in the second unlocking position and the first buckle member is slid from the first locking position to a first unlocking position, the first buckle member pushes the second buckle member to rotate towards the second locking position, so that the second clamping portion blocks the second clamping groove.

Description

Technical Field

[0001] This invention relates to a snap-fit ​​mechanism, and more particularly to a snap-fit ​​mechanism that ensures the correctness and safety of assembly and disassembly. Background Technology

[0002] Servers are used in network systems to serve various computers or portable electronic devices. Currently, some servers are equipped with multiple detachable modules (e.g., adapter modules, docking stations, etc.) to meet diverse functional requirements. For easy maintenance, these modules are assembled and disassembled using snap-fit ​​mechanisms. However, if the snap-fit ​​mechanism fails to securely lock the module, it may fall and be damaged during assembly or disassembly, potentially causing injury to the user. Summary of the Invention

[0003] The present invention provides a snap-fit ​​mechanism that can ensure the correctness and safety of assembly and disassembly, thereby solving the above-mentioned problems.

[0004] According to one embodiment, the latching mechanism of the present invention includes a housing, a first latching member, and a second latching member. The housing has a first latching groove and a second latching groove. The first latching member is slidably disposed in the housing and has a first latching portion. The second latching member is rotatably disposed in the housing and has a second latching portion. When the first latching member is in a first locked position, the first latching portion blocks the first latching groove, and the second latching member can rotate between a second locked position and a second unlocked position. When the second latching member is in the second unlocked position, and the first latching member slides from the first locked position to the first unlocked position, the first latching portion moves away from the first latching groove, and the first latching member pushes the second latching member to rotate toward the second locked position, so that the second latching portion blocks the second latching groove.

[0005] In summary, the latching mechanism of the present invention is equipped with a slidable first latching member and a rotatable second latching member. The first latching member can slide between a first locked position and a first unlocked position to assemble or disassemble the first assembly module. When the first latching member is in the first locked position, the second latching member can rotate between a second locked position and a second unlocked position to assemble or disassemble the second assembly module. When the second latching member is in the second unlocked position, and the first latching member slides from the first locked position to the first unlocked position, the first latching member pushes the second latching member to rotate toward the second locked position. In other words, when the first latching member is in the first unlocked position, the first latching member limits the second latching member, preventing the second latching member from rotating toward the second unlocked position. At this time, if the second assembly module is assembled onto the housing, the second assembly module cannot be disassembled; if the second assembly module is not yet assembled onto the housing, the second assembly module cannot be assembled. Therefore, only when the first latch securely locks the first assembly module to the housing (i.e., the first latch is in the first locked position) can the user operate the second latch to rotate between the second locked position and the second unlocked position to assemble or disassemble the second assembly module. This ensures the correctness and safety of assembling and disassembling the assembly module.

[0006] The advantages and spirit of the present invention can be further understood from the following detailed description of the invention and the accompanying drawings. Attached Figure Description

Figure 9 for Figure 8 Exploded view of the latching mechanism 1, the first assembly module 30, the second assembly module 32, and the third assembly module 34. Figure 10 for Figure 8 The locking mechanism 1 in the middle is shown in a perspective view of locking the second assembly module 32.

[0068] like Figures 1 to 4As shown, the latching mechanism 1 includes a housing 10, a first latching member 12, a second latching member 14, and a third latching member 16. The latching mechanism 1 can be applied to servers to latch multiple detachable assembly modules (e.g., adapter modules, base modules, etc.) onto the housing 10, enabling the server to meet various functional requirements. Furthermore, the latching mechanism 1 can also be applied to other devices requiring latching, depending on the specific application. It should be noted that the latching mechanism 1 of this invention has a generally symmetrical structure; therefore, the first latching member 12, the second latching member 14, the third latching member 16, and their corresponding components are provided on both sides of the latching mechanism 1.

[0069] The first latching member 12 is slidably disposed in the housing 10. In this embodiment, the housing 10 may have a first sliding portion 100, and the first latching member 12 may have a first sliding groove 120. The first sliding portion 100 is disposed in the first sliding groove 120, such that the first latching member 12 can be in a first locked position (e.g., Figure 3 (as shown) and the first unlock position (as shown) Figure 6 The first latch 12 can slide back and forth relative to the housing 10 through the cooperation of the first sliding part 100 and the first latch 12. In practical applications, two first sliding parts 100 and two first sliding grooves 120 can be provided at appropriate positions on the housing 10 and the first latch 12, so that the first latch 12 can slide back and forth relative to the housing 10 through the cooperation of the first sliding part 100 and the first sliding groove 120.

[0070] like Figure 3 and Figure 4 As shown, the housing 10 has a first slot 101, and the first latching member 12 has a first latching portion 122. In practical applications, two first slots 101 and two first latching portions 122 can be provided at appropriate positions on the housing 10 and the first latching member 12. When the first latching member 12 is in the first locked position, the first latching portion 122 will block the first slot 101, such as... Figure 3 As shown. When the first latching member 12 slides from the first locking position to the first unlocking position, the first latching part 122 will move away from the first latching groove 101, as... Figure 6 As shown.

[0071] like Figure 2 and Figure 4As shown, the housing 10 may have two first positioning holes 102a and 102b, and the first latching member 12 may have a first positioning part 124, wherein the first positioning part 124 engages with one of the two first positioning holes 102a and 102b to position the first latching member 12 in a first locked position or a first unlocked position. In this embodiment, when the first latching member 12 is in the first locked position, the first positioning part 124 engages with the first positioning hole 102a to position the first latching member 12 in the first locked position; when the first latching member 12 is in the first unlocked position, the first positioning part 124 engages with the first positioning hole 102b to position the first latching member 12 in the first unlocked position.

[0072] like Figure 4 As shown, the housing 10 may have a first through hole 103, and the first latching member 12 may have a first operating portion 126, wherein the first operating portion 126 is exposed in the first through hole 103. Therefore, the user can push the first operating portion 126 through the first through hole 103 to slide the first latching member 12 between a first locked position and a first unlocked position. In this embodiment, the first operating portion 126 may be a hole, but is not limited thereto. In another embodiment, the first operating portion 126 may also be a protrusion or other structures operable by the user.

[0073] The second latching member 14 is rotatably disposed within the housing 10. In this embodiment, the second latching member 14 can be pivotally connected to the housing 10 via a pivot 18, such as... Figure 3 As shown. Furthermore, the housing 10 may have a second sliding portion 104, and the second latching member 14 may have a second sliding groove 140. The second sliding portion 104 is disposed in the second sliding groove 140, such that the second latching member 14 can be in a second locked position (e.g., Figure 3 (as shown) and the second unlock position (as shown) Figure 5 Rotate between (as shown).

[0074] like Figure 3 and Figure 4 As shown, the housing 10 has a second slot 105, and the second latching member 14 has a second latching portion 142. When the second latching member 14 is in the second locked position, the second latching portion 142 will block the second slot 105, such as... Figure 3 As shown. When the second latching member 14 rotates from the second locking position to the second unlocking position, the second latching part 142 will move away from the second latching groove 105, as... Figure 5 As shown.

[0075] like Figure 2 and Figure 4As shown, the housing 10 may have two second positioning holes 106a and 106b, and the second latching member 14 may have a second positioning portion 144, wherein the second positioning portion 144 engages with one of the two second positioning holes 106a and 106b to position the second latching member 14 in a second locked position or a second unlocked position. In this embodiment, when the second latching member 14 is in the second locked position, the second positioning portion 144 engages with the second positioning hole 106a to position the second latching member 14 in the second locked position; when the second latching member 14 is in the second unlocked position, the second positioning portion 144 engages with the second positioning hole 106b to position the second latching member 14 in the second unlocked position.

[0076] like Figure 4 As shown, the housing 10 may have a second through hole 107, and the second latching member 14 may have a second operating portion 146, wherein the second operating portion 146 is exposed in the second through hole 107. Therefore, the user can push the second operating portion 146 through the second through hole 107 to rotate the second latching member 14 between a second locked position and a second unlocked position. In this embodiment, the second operating portion 146 may be a hole, but is not limited thereto. In another embodiment, the second operating portion 146 may also be a protrusion or other structures operable by the user.

[0077] The third latching member 16 is slidably disposed in the housing 10. In this embodiment, the housing 10 may have a third sliding portion 108, and the third latching member 16 may have a third sliding groove 160. The third sliding portion 108 is disposed in the third sliding groove 160, such that the third latching member 16 can be in a third locked position (e.g., Figure 3 (as shown) and the third unlock position (as shown) Figure 7 The third latch 16 can slide between the housing 10 and the third latch 16 (as shown). In practical applications, two third sliding parts 108 and two third sliding grooves 160 can be provided at appropriate positions on the housing 10 and the third latch 16, so that the third latch 16 can slide back and forth relative to the housing 10 through the cooperation of the third sliding parts 108 and the third sliding grooves 160. In this embodiment, the first latch 12 and the third latch 16 can be arranged in parallel, that is, the sliding directions of the first latch 12 and the third latch 16 can be parallel to each other.

[0078] like Figure 3 and Figure 4 As shown, the housing 10 has a third slot 109, and the third latching member 16 has a third latching portion 162. In practical applications, two third slots 109 and two third latching portions 162 can be provided at appropriate positions on the housing 10 and the third latching member 16. When the third latching member 16 is in the third locked position, the third latching portion 162 will block the third slot 109, such as... Figure 3As shown. When the third latch 16 slides from the third locking position to the third unlocking position, the third latch part 162 will move away from the third latch slot 109, as... Figure 7 As shown. In this embodiment, the opening direction D1 of the first slot 101 is opposite to the opening direction D3 of the third slot 109 (e.g., Figure 4 As shown), therefore, the first assembly module 30 and the third assembly module 34 are assembled to the housing 10 in opposite directions (as shown). Figure 8 and Figure 9 (As shown). Furthermore, the opening direction D2 of the second slot 105 is the same as the opening direction D3 of the third slot 109 (as shown). Figure 4 As shown), therefore, the third assembly module 34 and the second assembly module 32 are sequentially assembled into the housing 10 in the same direction (as shown). Figure 8 and Figure 9 (As shown).

[0079] like Figure 2 and Figure 4 As shown, the housing 10 may have two third positioning holes 110a and 110b, and the third latching member 16 may have a third positioning portion 164, wherein the third positioning portion 164 engages with one of the two third positioning holes 110a and 110b to position the third latching member 16 in a third locked position or a third unlocked position. In this embodiment, when the third latching member 16 is in the third locked position, the third positioning portion 164 engages with the third positioning hole 110a to position the third latching member 16 in the third locked position; when the third latching member 16 is in the third unlocked position, the third positioning portion 164 engages with the third positioning hole 110b to position the third latching member 16 in the third unlocked position.

[0080] like Figure 4 As shown, the housing 10 may have a third through hole 111, and the third latching member 16 may have a third operating portion 166, wherein the third operating portion 166 is exposed in the third through hole 111. Therefore, the user can push the third operating portion 166 through the third through hole 111 to slide the third latching member 16 between a third locked position and a third unlocked position. In this embodiment, the third operating portion 166 may be a hole, but is not limited thereto. In another embodiment, the third operating portion 166 may also be a protrusion or other structures operable by the user.

[0081] like Figure 3 and Figure 5 As shown, when the first latching member 12 is in the first locked position and the third latching member 16 is in the third locked position, the first latching part 122 blocks the first latching groove 101, the third latching part 162 blocks the third latching groove 109, and the second latching member 14 can be in the second locked position (e.g., Figure 3 (as shown) and the second unlock position (as shown) Figure 5Rotate between (as shown).

[0082] like Figure 5 and Figure 6 As shown, when the second latching member 14 is in the second unlocking position and the first latching member 12 slides from the first locking position to the first unlocking position, the first latching part 122 moves away from the first slot 101, and the first latching member 12 pushes the second latching member 14 to rotate toward the second locking position, so that the second latching part 142 blocks the second slot 105.

[0083] like Figure 5 and Figure 7 As shown, when the second latching member 14 is in the second unlocking position and the third latching member 16 slides from the third locking position to the third unlocking position, the third latching part 162 moves away from the third slot 109, and the third latching member 16 pushes the second latching member 14 to rotate toward the second locking position, so that the second latching part 142 blocks the second slot 105.

[0084] like Figures 8 to 10 As shown, the latching mechanism 1 can be used to latch the first assembly module 30, the second assembly module 32, and the third assembly module 34. When the latching mechanism 1 is applied to a server, the first assembly module 30 and the third assembly module 34 can be server adapter modules, and the second assembly module 32 can be a server base module. In practical applications, the adapter module can be equipped with a solid-state drive, expansion card, and / or other electronic components; the base module can be equipped with a server board, riser cable module, network interface card (NIC), and / or other electronic components; and the housing 10 can be equipped with a switchboard, riser card module, and / or other electronic components.

[0085] In this embodiment, the first assembly module 30 has a first protrusion 300, the second assembly module 32 has a second protrusion 320, and the third assembly module 34 has a third protrusion 340. It should be noted that the number and position of the first protrusion 300, the second protrusion 320, and the third protrusion 340 correspond to the number and position of the first slot 101, the second slot 105, and the third slot 109, respectively.

[0086] When a user wishes to assemble or disassemble the first assembly module 30, the user can first operate the first latch 12 to slide it to the first unlocking position (e.g., Figure 6(As shown), the first protrusion 300 of the first assembly module 30 is then inserted into or removed from the first slot 101. When the first latch 12 is in the first unlocking position, the first latch 12 will limit the second latch 14, preventing the second latch 14 from rotating toward the second unlocking position. At this time, if the second assembly module 32 is assembled onto the housing 10, the second assembly module 32 cannot be disassembled; if the second assembly module 32 is not yet assembled onto the housing 10, the second assembly module 32 cannot be assembled. After the first protrusion 300 of the first assembly module 30 is inserted into the first slot 101, the user can operate the first latch 12 to slide to the first locking position (e.g., Figure 3 As shown), the first latching part 122 latches the first protrusion 300 into the first latching groove 101 (as shown). Figure 8 (As shown), to lock the first assembly module 30 onto the housing 10.

[0087] Similarly, when a user wants to assemble or disassemble the third assembly module 34, the user can first operate the third latch 16 to slide to the third unlocking position (e.g., Figure 7 (As shown), the third protrusion 340 of the third assembly module 34 is then inserted into or removed from the third slot 109. When the third latch 16 is in the third unlocking position, the third latch 16 will limit the second latch 14, preventing the second latch 14 from rotating toward the second unlocking position. At this time, if the second assembly module 32 is assembled onto the housing 10, the second assembly module 32 cannot be disassembled; if the second assembly module 32 is not yet assembled onto the housing 10, the second assembly module 32 cannot be assembled. After the third protrusion 340 of the third assembly module 34 is inserted into the third slot 109, the user can operate the third latch 16 to slide to the third locking position (as shown). Figure 3 As shown), the third latching part 162 latches the third protrusion 340 into the third latching groove 109 (as shown). Figure 8 (as shown), to lock the third assembly module 34 onto the housing 10.

[0088] Therefore, only when the first latching member 12 and the third latching member 16 securely lock the first assembly module 30 and the third assembly module 34 onto the housing 10 (i.e., the first latching member 12 is in the first locked position and the third latching member 16 is in the third locked position) can the user operate the second latching member 14 to rotate between the second locked position and the second unlocked position to assemble or disassemble the second assembly module 32. This ensures the correctness and safety of the assembly and disassembly of the assembly module. After the second protrusion 320 of the second assembly module 32 is inserted into the second slot 105, the user can operate the second latching member 14 to rotate to the second locked position (e.g., ...). Figure 3 As shown), the second latching part 142 latches the second protrusion 320 into the second latching groove 105 (as shown). Figure 10 (As shown), to lock the second assembly module 32 onto the housing 10.

[0089] In another embodiment, the buckling mechanism 1 of the present invention may omit the first buckling member 12 or the third buckling member 16 described above, depending on the actual application.

[0090] Please see Figure 11 , Figure 11 for Figure 1 The latching mechanism 1 is shown in a three-dimensional view from another perspective.

[0091] like Figure 11 As shown, the latching mechanism 1 may further include a fourth latching member 20, wherein the fourth latching member 20 and its corresponding components are provided on both sides of the latching mechanism 1. The fourth latching member 20 may also be slidably disposed in the housing 10 and opposite to the second latching member 14. The second latching member 14 and the fourth latching member 20 respectively latch the opposite ends of the second assembly module 32 to lock the second assembly module 32 onto the housing 10. It should be noted that the detailed structure and working principle of the fourth latching member 20 are roughly the same as those of the first latching member 12 and the third latching member 16 described above, and will not be repeated here.

[0092] Please see Figures 12 to 17 , Figure 12 This is a partial perspective view of the latching mechanism 1' according to another embodiment of the present invention. Figures 13 to 15 Assemble the first assembly module 30 to Figure 12 A partial 3D view of the process of the latching mechanism 1' in the middle. Figure 16 and Figure 17 For the first assembly module 30 self Figure 12 A partial perspective view of the disassembly process of the latching mechanism 1'. It should be noted that, in order to clearly show the operation process of the first latching component 12 and the first assembly module 30, Figures 13 to 17 The shell 10 in the middle is represented by a dashed line.

[0093] like Figure 12 As shown, the latching mechanism 1' further includes an elastic element 22, wherein the two ends of the elastic element 22 are respectively connected to the housing 10 and the first latching member 12. The elastic element 22 is used to keep the first latching member 12 tending towards the first locking position (i.e., towards the direction of arrow A1). In this embodiment, the elastic element 22 may be a tension spring, but is not limited thereto. The elastic element 22 may also be other elements that can keep the first latching member 12 tending towards the first locking position, depending on the actual application. In this embodiment, the first latching portion 122 of the first latching member 12 has a first guide slope 128, and the first latching member 12 has a second guide slope 130 and a limiting groove 132, wherein the second guide slope 130 is opposite to the first latching portion 122, and the limiting groove 132 is adjacent to the second guide slope 130.

[0094] The first latching member 12 of the latching mechanism 1' can be used to latch the first assembly module 30, wherein the first assembly module 30 has a first protrusion 300. For example... Figure 13 As shown in Figure 14, when the first protrusion 300 of the first assembly module 30 is inserted into the first slot 101 of the housing 10, the first protrusion 300 pushes against the first guide slope 128, causing the first latching part 122 to move away from the first slot 101 in the direction of arrow A2. Furthermore, when the first protrusion 300 pushes against the first guide slope 128, the first latching member 12 is stretched in the direction of arrow A2. Figure 12 The elastic element 22 is shown. Next, as... Figure 15 As shown, when the first protrusion 300 is fully inserted into the first slot 101, Figure 12 The elastic element 22 shown will cause the first latching element 12 to return to its original position in the direction of arrow A1, so that the first latching part 122 latches the first protrusion 300 into the first slot 101, thereby locking the first assembly module 30 onto the housing 10. In other words, the user only needs to place the first protrusion 300 of the first assembly module 30 into the first slot 101 of the housing 10, and the automatic latching effect can be achieved through the configuration of the first guide slope 128 and the elastic element 22.

[0095] When the user wants to disassemble the first assembly module 30, the user must first operate the first latch 12 from the first locking position (e.g., Figure 15 As shown) Towards the first unlock position (as shown) Figure 17 As shown, the first latch 12 slides from the first locked position to the first unlocked position, and the second guide ramp 130 pushes against the first protrusion 300, causing the first protrusion 300 to move away from the first slot 101. Figure 16 As shown. Next, when the first protrusion 300 passes the second guide ramp 130, the first protrusion 300 will sink into the limiting groove 132 due to the weight of the first assembly module 30 itself (as shown). Figure 17 As shown), this restricts the first latch 12 from resetting to the first locked position. The user can then detach the first assembly module 30 from the housing 10. After the first protrusion 300 disengages from the limiting groove 132, Figure 12 The elastic element 22 shown will cause the first latching element 12 to reset in the direction of arrow A1, so that the first latching part 122 will block the first slot 101 again.

[0096] In this embodiment, the first assembly module 30 may have a first connector 302, and a second connector 112 may be installed in the housing 10. In this embodiment, the first connector 302 may be a slot connector, and the second connector 112 may be a gold finger connector, but is not limited thereto. When the first assembly module 30 is assembled in the housing 10, the first connector 302 is connected to the second connector 112, such as... Figure 15 As shown. When the second guide slope 130 of the first latching member 12 pushes against the first protrusion 300 of the first assembly module 30, the first assembly module 30 will drive the first connector 302 to move away from the second connector 112, so that the first connector 302 is at least partially disengaged from the second connector 112, as shown. Figure 16 As shown. This makes it easier for users to remove the first assembly module 30 later.

[0097] also, Figure 1 The first fastener 12 of the fastening mechanism 1 can Figure 12 The first latching member 12 of the latching mechanism 1' is replaced. When the first latching member 12 of the latching mechanism 1' is in the first unlocking position, the first latching member 12 of the latching mechanism 1' can also limit the second latching member 14, so that the second latching member 14 cannot rotate toward the second unlocking position. Of course, Figure 1 The third fastener 16 of the fastening mechanism 1 can also Figure 12 Replace the first fastener 12 of the fastening mechanism 1' in the middle.

[0098] In summary, the latching mechanism of the present invention is equipped with a slidable first latching member, a rotatable second latching member, and a slidable third latching member. The first latching member can slide between a first locking position and a first unlocking position to assemble or disassemble a first assembly module. The third latching member can slide between a third locking position and a third unlocking position to assemble or disassemble a third assembly module. When the first latching member is in the first locking position and the third latching member is in the third locking position, the second latching member can rotate between the second locking position and the second unlocking position to assemble or disassemble a second assembly module. When the second latching member is in the second unlocking position and the first latching member slides from the first locking position to the first unlocking position, the first latching member pushes the second latching member to rotate toward the second locking position. When the second latching member is in the second unlocking position and the third latching member slides from the third locking position to the third unlocking position, the third latching member also pushes the second latching member to rotate toward the second locking position. In other words, when the first latching member is in the first unlocking position and / or the third latching member is in the third unlocking position, the first latching member and / or the third latching member will limit the second latching member, preventing it from rotating towards the second unlocking position. At this time, if the second assembly module is assembled onto the housing, it cannot be disassembled; if the second assembly module is not yet assembled onto the housing, it cannot be assembled. Therefore, only when the first and third latching members securely lock the first and third assembly modules onto the housing (i.e., the first latching member is in the first locking position and the third latching member is in the third locking position) can the user operate the second latching member to rotate between the second locking position and the second unlocking position to assemble or disassemble the second assembly module. This ensures the correctness and safety of the assembly and disassembly of the assembly module. It should be noted that the latching mechanism of the present invention may omit the aforementioned first or third latching member, depending on the actual application. Furthermore, the present invention can also achieve an automatic latching effect through the configuration of the first guide ramp and the elastic member.
