In the case where it is impossible to observe whether the protruding portion is inserted into the card slot, by rotating the cover plate to push the PCIE card to continue moving into the PCIE card bracket, the protruding portion is completely inserted into the card slot, realizing the blind plugging action.

[0007] To achieve the above object, the present invention provides the following technical solution: A blind insertion structure at the PCIE card end of a server, including a PCIE card bracket and a PCIE card. The PCIE card bracket is a box-shaped structure with an opening at one end. A card slot is provided on the inner wall of the PCIE card bracket opposite to the opening. The bottom edge of the opening of the PCIE card bracket is also connected with a cover plate through a rotating shaft. When the cover plate rotates to the horizontal state, its top surface is flush with the bottom wall of the PCIE card bracket for supporting the PCIE card. A locking chute is also provided on the top surface of the cover plate;

[0008] Limiting plates for guiding are fixed on both symmetric sides of the PCIE card. A protruding part inserted into the card slot is fixed on one side of the PCIE card adjacent to the two limiting plates. A locking component sliding along the locking chute is installed on the other side of the PCIE card opposite to the protruding part. The locking component slides in the locking chute and drives the cover plate to rotate around the rotating shaft. When the cover plate rotates to the vertical direction and seals the opening of the PCIE card bracket, the protruding part is inserted into the card slot and the circuit is connected.

[0009] Further, one end port of the limiting plate facing the protruding part is a bevel for guiding the PCIE card to be inserted into the PCIE card bracket. There are two upper and lower limiting plates on the same side.

[0010] Further, a contact is provided in the card slot, and the wire harness led out by the contact passes through the PCIE card bracket. The gold finger of the protruding part inserted into the card slot contacts the contact in the card slot for circuit connection.

[0011] Further, the locking chute includes chute one and chute two. Chute one and chute two are connected. One ends of chute one and chute two both penetrate through the other side of the cover plate opposite to the rotating shaft, and the other ends of chute one and chute two do not penetrate through the cover plate. Among them, the end port of chute two facing the rotating shaft is semi-circular.

[0012] Further, the center of the rotating shaft and the center of the semi-circular port of chute two are on the same line, and the width of chute one is smaller than the width of chute two.

[0013] Further, the locking component includes a locking column, a connecting rod, a support seat, a support rod and a spring. The support seat is fixed on the PCIE card. The support rod is fixed in the support seat. One end of the connecting rod is inserted into the support seat and penetrated by the support rod. The other end of the connecting rod is fixed to the locking column. The spring is sleeved on the support rod, and both ends of the spring are fixed to the connecting rod and the support seat.

[0014] Further, the PCIE card is inserted from the opening of the PCIE card bracket. The locking column is inserted into chute two, and the connecting rod passes through chute one. The locking column abuts against the semi-circular opening of chute two for driving the cover plate to rotate around the rotating shaft to seal the opening.

[0015] Further, a strip-shaped groove is provided on the cover plate, and a handle covering half of the strip-shaped groove is also fixed on the cover plate.

[0016] A server includes a housing that supports a PCIE card bracket. A hole groove is provided on one side surface of the housing. The opening of the PCIE card bracket is aligned with the hole groove. When the cover plate seals the opening of the PCIE card bracket, it is flush with the outer wall of the housing. A circuit board is also provided inside the housing, and the wire harness led out by the contacts is inserted on the circuit board.

[0017] Further, a baffle for locking the cover plate is also provided on the outer wall of the housing beside the hole groove. The baffle rotates around the axis on the housing to the horizontal position to block the cover plate.

[0018] The technical effects and advantages of the present invention:

[0019] 1. The PCIE card bracket is fixed inside the housing. Only need to open the cover plate and let the cover plate rotate in the hole groove, so as to expose the opening of the PCIE card bracket.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Refer to Figure 1 , a server, including a housing body 6 for supporting the PCIE card bracket 1. A hole groove is provided on one side surface of the housing body 6. The opening of the PCIE card bracket 1 is aligned with the hole groove, and when the cover plate 11 seals the opening of the PCIE card bracket 1, it is flush with the outer wall of the housing body 6. A circuit board is also provided inside the housing body 6, and the wire harness led out by the contacts is inserted on the circuit board.

[0035] The PCIE card bracket 1 is fixed inside the housing 6. Only need to open the cover plate 11 and let the cover plate 11 rotate in the hole groove, so as to expose the opening of the PCIE card bracket 1. At this time, it is not necessary to remove the PCIE card bracket 1 from the server, and the PCIE card 2 can be inserted into the PCIE card bracket 1 through the hole groove, which simplifies the card insertion steps. Compared with the existing method of first removing the PCIE card bracket 1 from the server and then inserting the PCIE card 2 into the PCIE card bracket 1, the existing disassembly steps adopt a multiple disassembly method, and the disassembly method is cumbersome, resulting in the inability to achieve the purpose of blind insertion or blind disassembly.

[0036] Example 1: Refer to Figure 2 , Figure 4 , Figure 7 , which is the first embodiment of the present invention, provides a blind insertion structure at the PCIE card end of a server. The blind insertion structure at the PCIE card end of the server includes a PCIE card bracket 1 and a PCIE card 2. The PCIE card bracket 1 is a box-shaped structure with an opening at one end. A card slot 3 is provided on the inner wall of the PCIE card bracket 1 opposite to the opening. The bottom edge of the opening of the PCIE card bracket 1 is also connected with a cover plate 11 through a rotating shaft 12. When the cover plate 11 rotates to the horizontal state, its top surface is flush with the bottom wall of the PCIE card bracket 1, and is used to support the PCIE card 2.

[0037] When the rotation angle of the cover plate 11 is 0° - 90°, when the cover plate 11 rotates to the horizontal position, it is at 0°. At this time, the top surface of the cover plate 11 is flush with the bottom wall of the PCIE card bracket 1, and a part of the PCIE card 2 is placed on the cover plate 11, so that the PCIE card 2 and the opening of the PCIE card bracket 1 are on the same horizontal plane, so as to first place the PCIE card 2 at the opening position of the PCIE card bracket 1 to initially realize the blind insertion step.

[0038] Limit plates 21 for guiding are fixed on both symmetric sides of the PCIE card 2. One end port of the limit plate 21 facing the convex part 22 is a slope, which is used to guide the PCIE card 2 to be inserted into the PCIE card bracket 1. There are two upper and lower limit plates 21 on the same side. A convex part 22 inserted into the card slot 3 is fixed on one side of the PCIE card 2 adjacent to the two limit plates 21. The convex part 22 is inserted into the card slot 3 and the circuit is connected. Contacts are provided in the card slot 3, and the wire harness led out by the contacts passes through the PCIE card bracket 1. The gold finger of the convex part 22 inserted into the card slot 3 contacts the contacts in the card slot 3 for circuit connection.

[0039] The raised portion 22 of the PCIE card 2 is used to determine the insertion direction, so that one side of the raised portion 22 is aligned with the opening of the PCIE card bracket 1. The inclined limiting plates 21 are arranged on both sides of the PCIE card 2 to reduce the front end size to facilitate the insertion of the PCIE card 2 and the limiting plate 21. The opening size of the PCIE card bracket 1 is matched with the size of the PCIE card 2 and the limiting plate 21. Since the port of the limiting plate 21 close to the raised portion 22 is the narrowest, the PCIE card 2 slides on the cover plate 11 to guide a part of the PCIE card 2 to be inserted into the opening of the PCIE card bracket 1. When the PCIE card 2 is fully inserted into the opening of the PCIE card bracket 1, due to the inclined structure of the limiting plate 21, the angle of the PCIE card 2 is slowly corrected, thereby realizing a blind insertion operation.

[0040] When the PCIE card 2 is fully inserted into the PCIE card bracket 1, the outer wall of the limit plate 21 contacts the inner wall of the PCIE card bracket 1 to achieve the purpose of limitation, and the protrusion 22 is inserted into the card slot 3, and the gold finger contacts the contact point in the card slot 3 to complete the insertion of the PCIE card 2. After the insertion, the cover plate 11 is rotated 90°, and the cover plate 11 is against the PCIE card 2, thereby improving the firmness of the connection between the PCIE card 2 and the PCIE card bracket 1.

[0041] Example 2: Reference Figures 2 - 9 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment. During the implementation of the first embodiment, it is found that the process of the protrusion 22 being inserted into the card slot 3 is blocked by the PCIE card bracket 1, and it is impossible to know whether the protrusion 22 is completely inserted into the card slot 3.

[0042] In order to solve the above problem, this embodiment cooperates with the locking component 5 and the locking groove 4 to allow the locking component 5 to slide and drive the cover 11 to rotate, so that the protrusion 22 is inserted into the card slot 3. The cover 11 can rotate 90°, and ensure that when the cover 11 contacts the opening of the PCIE card bracket 1, the protrusion 22 is fully inserted into the card slot 3, and the gold finger of the card slot 3 contacts the contact in the card slot 3 to ensure that the blind-inserted protrusion 22 is fully inserted into the card slot 3.

[0043] A locking component 5 that slides along the locking groove 4 is installed on the other side of the PCIE card 2 opposite to the protrusion 22. The locking component 5 slides in the locking groove 4 and drives the cover 11 to rotate around the rotation axis 12. When the cover 11 rotates to a vertical direction and seals the opening of the PCIE card bracket 1, a locking groove 4 is also opened on the top surface of the cover 11. A strip groove is provided on the cover 11. A handle 111 covering half of the strip groove is also fixed on the cover 11. The handle 111 does not completely seal the strip groove. A fulcrum is provided on the cover 11 by inserting a finger into the strip groove and pressing the handle 111.

[0044] The locking chute 4 includes a first chute 41 and a second chute 42. The first chute 41 and the second chute 42 are connected. One ends of the first chute 41 and the second chute 42 penetrate through the other side of the cover plate 11 opposite to the rotating shaft 12, and the other ends of the first chute 41 and the second chute 42 do not penetrate through the cover plate 11. Among them, the port of the second chute 42 facing the rotating shaft 12 is semi-circular.

[0045] The center of the rotating shaft 12 and the center of the semi-circular port of the second chute 42 are on the same line, and the width of the first chute 41 is smaller than the width of the second chute 42.

[0046] The lock component 5 includes a lock post 51, a connecting rod 52, a support seat 53, a support rod 54 and a spring 55. The support seat 53 is fixed on the PCIE card 2. The support rod 54 is fixed inside the support seat 53. One end of the connecting rod 52 is inserted into the support seat 53 and penetrated by the support rod 54. The other end of the connecting rod 52 is fixed to the lock post 51. The spring 55 is sleeved on the support rod 54, and both ends of the spring 55 are fixed to the connecting rod 52 and the support seat 53.

[0047] The support seat 53 is of a rectangular frame structure. The support rod 54 is in a vertical state, and the port of the connecting rod 52 located inside the support seat 53 will be located in the support seat 53.

[0048] The first chute 41 and the second chute 42 are arranged side by side up and down. After the PCIE card 2 is corrected by the limit plate 21, a part of it is inserted into the PCIE card bracket 1. When the PCIE card 2 is not inserted into the PCIE card bracket 1 and there is no external force, the spring 55 pushes the connecting rod 52 downward and the connecting rod 52 contacts the bottom end of the support seat 53 to limit the position of the downward movement of the connecting rod 52. At this time, the lock post 51 is aligned with the second chute 42.

[0049] The PCIE card 2 is inserted through the opening of the PCIE card bracket 1. The lock post 51 is inserted into the second chute 42, and the connecting rod 52 passes through the first chute 41. The lock post 51 abuts against the semi-circular opening of the second chute 42 to drive the cover plate 11 to rotate around the rotating shaft 12 to seal the opening.

[0050] The limit plate 21 in Embodiment 1 is used to guide the PCIE card 2 to be accurately inserted into the PCIE card bracket 1, adjust the position of the locking post 51 to align with the second chute 42. As the PCIE card 2 is continuously inserted, the locking post 51 slowly inserts into the second chute 42, and the connecting rod 52 passes through the first chute 41. At this time, continue to insert the PCIE card 2 to disengage from the cover plate 11, and the locking post 51 moves to the semi-circular port of the second chute 42. Then continue to push the PCIE card 2. Since the width of the first chute 41 is smaller than that of the second chute 42, the locking post 51 cannot disengage from the first chute 41. As the PCIE card 2 continues to move into the PCIE card bracket 1, and the cover plate 11 can only rotate around the rotating shaft 12, the cover plate 11 will be pulled and rotated by the locking post 51. At this time, just push the cover plate 11 to seal the opening of the PCIE card bracket 1. Instead, the cover plate 11 pushes the PCIE card 2 to continue moving into the PCIE card bracket 1, and the locking post 51 and the connecting rod 52 rise along the support rod 54, and the spring 55 is slowly compressed. When the cover plate 11 rotates to the vertical direction and abuts against the opening of the PCIE card bracket 1, the protruding part 22 is completely inserted into the card slot 3, and the gold fingers of the protruding part 22 contact the contacts in the card slot 3 to achieve circuit conduction. When the PCIE card 2 is completely located in the PCIE card bracket 1 and it is impossible to observe whether the protruding part 22 is inserted into the card slot 3, the blind insertion operation is realized. On the outer wall of the housing 6 beside the hole slot, there is also a baffle for locking the cover plate 11. The baffle rotates around the shaft on the housing 6 to the horizontal position to block the cover plate 11. After the blind insertion is completed, rotate the baffle to abut against the cover plate 11 to prevent the cover plate 11 from rotating around the rotating shaft 12.

[0051] Moreover, it is also convenient to replace the PCIE card 2. Just rotate the baffle in the reverse direction to disengage the cover plate 11 and the baffle. Hold the handle 111 of the cover plate 11 and rotate it around the rotating shaft 12, which will drive the PCIE card 2 to move outwards instead. At this time, the protruding part 22 disengages from the card slot 3. When the cover plate 11 rotates to the horizontal position and cannot rotate further, the PCIE card 2 moves outwards, the locking post 51 disengages from the second chute 42, and the connecting rod 52 disengages from the first chute 41. Finally, take out the PCIE card 2 from the PCIE card bracket 1. The replacement is simple and there is no need to disassemble the server for replacement, which simplifies the steps for blind operation.

[0052] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
