DETAILED DESCRIPTION

[0034] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0035] like Figure 3-8 As shown, the present invention discloses a server card extraction aid structure, comprising a slot 3 capable of inserting a server card and an extraction aid component 4; the slot 3 is used for inserting a gold finger of the server card to achieve a secure installation and signal connection of the server card;

[0036] The auxiliary extraction assembly 4 includes a linkage plate 42, a support seat 43, a torsion spring device and a mounting shell 41 positioned and mounted with the slot 3; the mounting shell 41 is a rectangular shell structure with an upper opening;

[0037] The support seat 43 is installed at the left end of the installation shell 41 so as to slide and retract up and down. A first protrusion 432 is provided on the right side of the support seat 43. A support spring 433 capable of exerting an elastic force on the support seat 43 is provided on the installation shell 41, that is, the support seat 43 is a shell structure with an opening at the bottom. The support spring 433 is arranged inside the support seat 43 and supported by the bottom surface of the installation shell 41.

[0038] The torsion spring device is rotatably mounted on the right end of the mounting housing 41, and is provided with a swing arm 451, a connecting frame and a second protrusion 457. The swing arm 451 provides an ejection elastic force through the torsion spring device; the connecting frame is T-shaped, including a connecting rod 453 connected to the torsion spring device and a hanging rod 454 connected to the end of the connecting rod 453 away from the torsion spring device;

[0039] The linkage plate 42 is placed on the upper side of the bottom surface of the mounting housing 41 and can slide left and right. The left end of the linkage plate 42 is bent to form a first limiting portion 423 that can engage and limit the first convex block 432. The right end of the linkage plate 42 is bent to form a hanging portion 422 connected to the connecting frame. The hanging portion 422 is in a "冂" shape, and a notch for the hanging rod 454 to enter and exit is provided inside it. The hanging rod 454 is placed in the space formed by the hanging portion 422, and a vertical notch through which the connecting rod 453 can pass is provided on the outside of the hanging portion 422;

[0040] An unlocking elastic piece 46 is also installed on the mounting housing 41, and a second limiting portion 461 that can engage and limit the second convex block 457 is provided on the unlocking elastic piece 46.

[0041] When the server card is inserted into the slot 3, the left and right sides of the lower part of the server card will respectively press down on the upper ends of the support seat 43 and the swing arm 451. The torsion spring device rotates against the elastic force of the coil spring 456, and the second convex block 457 is engaged and limited by the second limiting portion 461 on the unlocking elastic piece 46; at the same time, the linkage plate 42 is pushed to the left through the connecting rod 453 and the hanging rod 454, so that the first limiting portion 423 engages and limits the first convex block 432, thereby realizing the reliable installation of the server card. When the server card is pulled out, the unlocking elastic piece 46 is operated to release the engagement and limitation of the second convex block 457 by the second limiting portion 461 on it. Under the torsional force of the torsion spring device, the right end of the server card is jacked up by the end of the swing arm 451; at the same time, the hanging portion 422 is pulled to the right through the connecting rod 453 and the hanging rod 454, so that the linkage plate 42 moves to the right, thereby releasing the engagement and limitation of the first convex block 432 by the first limiting portion 423. The support seat 43 jacks up the left end of the server card under the supporting elastic force of the support spring 433; forces are applied to both the left and right ends of the server card to realize the balanced and stable auxiliary pulling out of the server card. The overall structure is simple, occupies a small space, can be flexibly installed and used, and will not interfere with other components; it is convenient to use and can efficiently and simply realize the disassembly and assembly actions of the server card; and the plugging and unplugging are labor-saving and safe, without the need to use production line jigs and fixtures, etc., reducing production costs.

[0042] Among them, the torsion spring device includes a coil spring shaft 455, a coil spring 456 and a torsion spring chamber 45 that are fixedly installed on the mounting housing 41. The coil spring shaft 455 and the torsion spring chamber 45 are respectively connected to the inner and outer sides of the coil spring 456; the swing arm 451, the connecting frame and the second convex block 457 are respectively fixedly installed on the torsion spring chamber 45. By positioning the inner end of the coil spring 456 through the coil spring shaft 455, the torsion spring chamber 45 (together with the swing arm 451, the connecting frame, and the second convex block 457) can have a torsional elastic force in one direction, and the structure is simple and easy to implement.

[0043] The end of the swing arm 451 away from the torsion spring bin 45 is rotatably mounted with a rotation support block 47. The rotation support block 47 is rotatably connected to the end of the swing arm 451 to ensure that its upper surface is always in contact with the lower part of the server card, thereby ensuring the reliability of assisting the extraction of the server card.

[0044] The mounting housing 41 is also provided with a return spring 424 that elastically supports the linkage plate 42 in the direction of the support seat 43. That is, the return spring 424 has a certain pushing force in the left direction on the linkage plate 42 (the pushing force here is much smaller than the torsion of the coil spring 456). When the server card is inserted, the return spring 424 pushes the linkage plate 42 to the left, which can realize the reliability of the first limit part 423 inserting the first protrusion 432, and can avoid the phenomenon of the connection position of the connection frame and the hanging part 422 being stuck, thereby ensuring the reliability of use.

[0045] The support seat 43 is provided with a slide shaft 431, and the mounting housing 41 is provided with a slide groove 411 capable of guiding the slide shaft 431 in the upward and downward directions. The slide groove 411 guides the slide shaft 431 in the upward and downward directions, thereby ensuring the precision and reliability of the upward and downward sliding of the support seat 43. The upper side of the slide groove 411 has a limiting effect on the slide shaft 431, effectively preventing the support seat 43 from being excessively ejected, and ejecting the server card upward by 10 mm, thereby ensuring that the server card is completely removed from the slot 3, thereby achieving convenient disassembly.

[0046] Among them, a limiting shaft 452 is provided on the swing arm 451, and a limiting groove 412 capable of limiting the limiting shaft 452 is provided on the mounting housing 41. The limiting shaft 452 is limited by the limiting groove 412, so as to limit the downward rotation angle of the torsion spring chamber 45; and when the server card is inserted and installed, the limiting shaft 452 can be manually operated to press down the rotating support block 47. When the limiting shaft 452 is inserted into the limiting groove 412, the second limiting portion 461 is engaged and limited to the second protrusion 457, and at the same time cooperates with the server card to press down the support seat 43, so that the server card can be inserted and installed conveniently.

[0047] The upper end of the unlocking spring 46 is provided with an operating part folded outward, and the lower end of the unlocking spring 46 is riveted to the inner wall of the mounting shell 41. The mounting shell 41 is provided with an operating window 413 for the operating part to extend out for operation. By bending the operating part, the unlocking spring 46 can be elastically bent, so that the second limiting part 461 can unlock the second protrusion 457. The structure is simple, the design is compact, and the practicability is good.

[0048] At least two guide posts 44 are provided on the bottom surface of the mounting housing 41, and a long guide hole 421 capable of left and right guiding with the guide posts 44 is provided on the linkage plate 42. The accuracy and reliability of left and right sliding of the linkage plate 42 can be achieved by slidingly guiding the guide posts 44 with the guide holes 421.

[0049] The slot 3 is positioned and installed by the mounting plate 5 and the guide column 44. The mounting plate 5 is positioned and installed on the guide column 44, and the slot 3 is positioned and installed on the mounting plate 5. The structure design is compact and reasonable, ensuring that the auxiliary pull structure occupies a small space and avoiding interference with other components.

[0050] like Figure 1-2 As shown, the present invention also discloses a PCIE card module, including a bracket 2 and a server card auxiliary extraction structure; the mounting housing 41 is positioned and installed with the bracket 2, and the slot 3 is used for plugging and installing the PCIE card 1. The mounting plate 5 is a single-slot customized riser card, and the slot 3 is opened on the riser card. The server card auxiliary extraction structure realizes the auxiliary extraction operation of the PCIE card 1 and the riser card, and the structure is simple and compact, and will not interfere with other components in the server.

[0051] The server card auxiliary extraction structure and PCIE card module have a simple overall structure, small space, can be flexibly installed and used, and will not interfere with other components; they are easy to use and can efficiently and simply realize the disassembly and assembly of the server card; and the plugging and unplugging is labor-saving and safe, and there is no need to use production line jigs and tooling, thereby reducing production costs. When pulling out the server card, the unlocking spring 46 is operated to release the engagement limit of the second protrusion 457 by the second limit part 461 thereon, and the right end of the server card is lifted upward by the end of the swing arm 451 under the torsion force of the torsion spring device; at the same time, the connecting part 422 is pulled to the right by the connecting rod 453 and the connecting rod 454, so that the linkage plate 42 moves to the right, so that the first limit part 423 releases the engagement limit of the first protrusion 432, and the support seat 43 pushes up the left end of the server card under the support elastic force of the support spring 433; the left and right ends of the server card are jointly applied to achieve balanced and stable auxiliary extraction of the server card.
