Description

Technical fields:

[0001] This utility model relates to the field of PCIE installation, and specifically to a PCIE expansion card disassembly and assembly structure. Background technology:

[0002] PCI Express (PCIe) is a high-speed serial computer expansion bus standard that uses a point-to-point serial communication architecture, replacing the traditional PCI and AGP buses. Its advantages include high bandwidth (e.g., PCIe 4.0 x16 single-lane can reach 32GB / s), low latency, and scalability (flexible adaptation to different devices through x1 / x4 / x8 / x16 lane configuration). PCIe supports hot-swapping and full-duplex communication, and is widely used in high-performance devices such as graphics cards, SSDs, and network cards. Its backward compatibility design ensures a smooth generational transition. The current PCIe 6.0 standard further increases the transmission rate to 64GT / s while maintaining electrical compatibility with older versions.

[0003] Chinese Patent Publication No. CN 220271846 U discloses a PCIe card fixing structure, including a bracket, a PCIe card, and a limiting mechanism. The bracket has a card slot; the PCIe card is inserted into the card slot; the limiting mechanism includes a guide rod, a telescopic spring, and a limiting member. The guide rod is connected to the bracket and passes through the limiting member through a guide hole. The telescopic spring is sleeved on the guide rod, allowing the limiting member to move along the guide rod from a first position to a second position. When the limiting member is in the first position, it avoids the PCIe card; when it is in the second position, it contacts the PCIe card. This utility model, through the coordinated operation of the guide rod, the telescopic spring, and the limiting member, enables tool-free installation and removal of the PCIe card, facilitating rapid installation and removal of the PCIe card.

[0004] As described in the aforementioned patent, most PCIe cards on the market are currently installed by fixing one end, and the PCIe card is inserted into the card slot and uses an interference fit to spring into place. However, this method of installation is not stable enough. When the unfixed end of the PCIe card is subjected to a pulling force, it is easy to come out of the card slot, resulting in unstable contact and even damage to the PCIe card.

[0005] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a PCIE expansion card disassembly and assembly structure.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a PCIE expansion card disassembly and assembly structure, comprising: a card slot for inserting a PCIE card, a locking member that can swing and fasten one end of the PCIE card is provided on the side of the card slot, a contact part for pressing and fastening with the locking member at the lower end of the PCIE card, and an unlocking block that contacts the locking member and can push the locking member to swing and release the contact part from its limit is provided on the side of the contact part.

[0008] Furthermore, in the above technical solution, the end of the locking member is provided with a lower contact platform for facilitating its swinging, and the lower end of the unlocking block is provided with a contact groove for engaging with the lower contact platform.

[0009] Furthermore, in the above technical solution, the lower contact platform is provided with a lower multi-level step area, the contact groove is set in a V-shape to press against the lower contact platform, and one side of the contact groove is formed with an upper multi-level step area corresponding to the lower multi-level step area.

[0010] Furthermore, in the above technical solution, a limiting structure for vertical positioning is provided between the upper part of the unlocking block and the PCIE card. This limiting structure vertically limits the unlocking block above the lower contact platform and prevents the unlocking block from swaying during the process of pushing the locking element to swing and unlock.

[0011] Furthermore, in the above technical solution, the limiting structure includes a mounting plate disposed on one side of the PCIE card and a limiting platform disposed on the unlocking block and in horizontal contact with and pressing against the mounting plate.

[0012] Furthermore, in the above technical solution, the unlocking block is fixed to the lower end of the mounting plate by the first screw and extends downward, and the limiting platform is in horizontal contact with the lower end surface of the mounting plate.

[0013] Furthermore, in the above technical solution, the upper end of the unlocking block is provided with a threaded hole post for connection with the first screw.

[0014] Furthermore, in the above technical solution, one end of the slot is provided with a support platform for hinged support of the locking element, and the lower end of the locking element is hinged to the support platform through a pin, which is located between the lower contact platform and the slot.

[0015] Furthermore, in the above technical solution, the locking member is provided with a locking groove for the contact part to extend into. One end of the locking groove is provided with a stop part that can engage with the contact part. The bottom of the locking groove is provided with an upper locking step that can drive the locking member to swing after pressing against the contact part, so that the stop part engages with the contact part. The upper locking step and the lower contact platform are located on both sides of the pin.

[0016] Furthermore, in the above technical solution, the support platform is provided with a locking groove for limiting the locking fastener after it is engaged with the contact part, and the locking fastener is provided with a locking block that can swing and elastically engage into the locking groove.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention uses an unlocking block that presses against the locking element on the PCIe card. When the PCIe card is inserted into the card slot, the contact part pushes the locking element to swing and engage with the contact part, thereby locking and fixing one end of the PCIe card. When the PCIe card is removed, after one end of the PCIe card is lifted, the unlocking block swings with the PCIe card and applies pressure to the locking element, thereby pushing the locking element to swing and unlock the contact part, so that the PCIe card can be smoothly pulled out of the card slot, realizing the removal of the PCIe card. This structure can not only solve the problem of inconvenient removal and installation of large PCIe cards, but also eliminates the need for an extended unlocking device to operate the locking element to unlock. The structure is simple and the removal and installation are efficient. Attached image description:

[0024] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0025] See Figures 1 to 6As shown, a PCIe expansion card disassembly and assembly structure includes a card slot 2 for inserting a PCIe card 1. A locking member 3 is provided on the side of the card slot 2, which can swing and fasten one end of the PCIe card 1. A contact part 11 is provided at the lower end of the PCIe card 1 for pressing and fastening with the locking member 3. An unlocking block 12 is provided on the side of the contact part 11, which contacts the locking member 3 and can push the locking member 3 to swing and release the contact part 11 from its limit. An unlocking block 12 is installed on the PCIe card 1, pressing against the locking member 3. When the PCIe card 1 is inserted into the card slot 2, the contact part 11 pushes the locking member 3 to swing and engage with the contact part 11, thus locking and fixing one end of the PCIe card 1. When the PCIe card 1 is removed, after one end of the PCIe card 1 is lifted, the unlocking block 12 swings with the PCIe card 1, applying pressure to the locking member 3, thereby pushing the locking member 3 to swing and unlock the contact part 11, allowing the PCIe card 1 to be smoothly pulled out of the card slot 2, thus removing the PCIe card 1. This structure not only solves the problem of inconvenient installation and removal of large PCIe cards 1, but also eliminates the need for an extended unlocking device to operate the locking member 3 to unlock. The structure is simple and the installation and removal are efficient.

[0026] The locking element 3 has a lower contact platform 31 at its end for easy swinging, and the unlocking block 12 has a contact groove 121 at its lower end for engaging with the lower contact platform 31. The contact groove 121 and the lower contact platform 31 are pressed together to achieve positioning of the locking element 3 and the unlocking block 12, preventing the contact groove 121 from loosening during use after the PCIE card 1 is installed.

[0027] The lower contact platform 31 is provided with a lower multi-step area 311, and the contact groove 121 is V-shaped and presses against the lower contact platform 31. One side of the contact groove 121 is formed with an upper multi-step area 122 corresponding to the lower multi-step area 311. By providing the lower multi-step area 311 and the upper multi-step area 122 in the lower contact platform 31 and the contact groove 121 respectively, not only can the PCIE card 1 be prevented from shaking after installation, but also the unlocking block 12 can be prevented from sliding when pushing the locking member 3 to swing during the removal of the PCIE card 1. This ensures that the unlocking block 12 applies stable force to the locking member 3 during the removal process and does not slip.

[0028] A limiting structure for vertical positioning is provided between the upper part of the unlocking block 12 and the PCIE card 1. This limiting structure vertically limits the unlocking block 12 above the lower contact platform 31 and prevents the unlocking block 12 from swaying during the process of pushing the locking member 3 to swing and unlock.

[0029] The limiting structure includes a mounting plate 13 disposed on one side of the PCIe card 1 and a limiting platform 123 disposed on the unlocking block 12 and horizontally contacting and pressing against the mounting plate 13. The unlocking block 12 is fixed to the lower end of the mounting plate 13 by a first screw 14 and extends downward, with the limiting platform 123 horizontally contacting and pressing against the lower end surface of the mounting plate 13. By setting the limiting platform 123 on the unlocking block 12 to contact and press against the mounting plate 13, the unlocking block 12 will not swing due to the reaction force when it applies force to the locking member 3, ensuring that the unlocking block 12 can smoothly push the locking member 3 to swing for a long time.

[0030] See Figure 1 As shown, in Embodiment 1, the upper end of the unlocking block 12 is provided with a threaded hole post 124 for connecting with the first screw 14. In this embodiment, the first screw 14 is first inserted through the mounting plate 13 and then inserted into the threaded hole post 124 to fix it to the unlocking block 12, thereby realizing the installation of the unlocking block 12. This installation method can effectively hide the first screw 14, making the appearance more aesthetically pleasing.

[0031] See Figure 2 As shown, in Embodiment 2, the first screw 14 passes through the unlocking block 12 first and is then fixed to the mounting plate 13 by a threaded structure. This method simplifies the installation of the unlocking block 12, and the shape and structure of the unlocking block 12 are also simpler, making it easier to process and produce.

[0032] One end of the slot 2 is provided with a support platform 21 for hinged support of the locking fastener 3. The lower end of the locking fastener 3 is hinged to the support platform 21 by a pin 22, which is located between the lower contact platform 31 and the slot 2.

[0033] The locking member 3 is provided with a locking groove 32 for the contact part 11 to extend into. One end of the locking groove 32 is provided with a stop part 321 that can be engaged with the contact part 11. The bottom of the locking groove 32 is provided with an upper locking step 322 that can drive the locking member 3 to swing after pressing against the contact part 11, so that the stop part 321 is engaged with the contact part 11. The upper locking step 322 and the lower contact platform 31 are located on both sides of the pin 22.

[0034] The support platform 21 is provided with a locking groove 211 for limiting the locking fastener 3 after it is engaged with the contact part 11. The locking fastener 3 is provided with a locking block 33 that can swing and elastically engage into the locking groove 211.

[0035] In summary, this utility model effectively secures one end of the PCIe card 1 by setting a locking element 3 on the side of the card slot 2 and engaging it with the contact part 11. Specifically:

[0036] When installing PCIe card 1, after PCIe card 1 is inserted into slot 2, contact part 11 contacts locking step 322 and pushes locking fastener 3 to swing so that stop part 321 swings and engages with contact part 11, locking one end of PCIe card 1 and realizing PCIe card 1 installation. At the same time, locking block 33 swings with locking fastener 3 into slot 211 to prevent locking fastener 3 from swinging and unlocking when PCIe card 1 is pulled out directly.

[0037] When removing PCIe card 1, first lift the other end of PCIe card 1. When the other end of PCIe card 1 is lifted, one end of PCIe card 1 swings, causing the unlocking block 12 to push the lower contact platform 31 of the locking member 3, pushing the locking member 3 to swing. After the locking member 3 swings, the stop part 321 disengages from the limiting pressure on the contact part 11 as the locking member 3 swings. At this time, PCIe card 1 can be pulled out of the card slot 2, realizing the removal of PCIe card 1.

[0038] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
