Description

Technical Field

[0001] This application relates to the field of computer equipment technology, and in particular to a board insertion and removal aid structure. Background Technology

[0002] A server is a computer that manages resources and provides services to users. Servers are typically categorized as file servers, database servers, and application servers. Servers are designed with a higher degree of integration; they also require greater operability and maintainability during installation and maintenance. With advancements in science and technology, design and manufacturing capabilities have continuously improved, leading to increased integration and smaller sizes of various types of internal server boards. However, when operating space is limited, operators cannot directly install or disassemble these boards.

[0003] Therefore, in view of the above-mentioned technical problems, how to improve the operability of board plug-in and plug-out when the operating space is limited is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this application is to provide a board insertion and removal assistance structure. This structure limits the six degrees of freedom of the board by a cover plate and a handle, and the handle extends the operable space of the board in its insertion and removal direction, thereby improving the board insertion and removal operability.

[0005] To achieve the above objectives, this application provides a board insertion and removal assist structure, which includes a handle that engages with the board and extends the length of the board in its insertion and removal direction. The handle is provided with a recessed groove, and engagement portions are provided on both sides of the recessed groove and located on the handle. The board is used to be placed in the recessed groove, and the two sides of the board are respectively engaged with the two recessed grooves. A limiting plate corresponding to the position of the engagement portion is provided on the end face of the handle, and the end face of the board abuts against the end face of the limiting plate.

[0006] A slidable cover plate is provided on the end face of the handle away from the limiting plate. The slidable cover plate is used to slide towards the plate, and the slidable cover plate engages with the handle. The engaged cover plate abuts against the end face of the plate away from the limiting plate.

[0007] The cover plate and the limiting plate are used together to limit the plate and the handle to be in the same plane.

[0008] Preferably, the handle is provided with two parallel elongated holes that are aligned with the insertion and removal direction of the card, and the cover plate is provided with a limiting member corresponding to the position of the two elongated holes. The limiting member passes through the elongated holes and is used to limit the cover plate to slide only along the length direction of the elongated holes.

[0009] Preferably, any of the limiting members includes:

[0010] A limiting block is located inside the elongated hole and is slidably disposed with respect to the elongated hole;

[0011] A limiting ring is located at the end of the limiting block away from the cover plate and abuts against the end face of the handle away from the cover plate, and the diameter of the limiting ring is greater than the width of the elongated hole.

[0012] Preferably, the elongated hole is provided with an annular groove, the diameter of which is larger than the diameter of the limiting ring. The limiting ring is used to extend into and pass through the annular groove, and after sliding with the sliding block, the limiting ring abuts against the end face of the handle away from the cover plate.

[0013] Preferably, the limiting block is elongated, and the two sides of the elongated block abut against and slide against the inner wall of the elongated hole.

[0014] Preferably, the cover plate is U-shaped, and the two sides of the U-shaped structure are used to abut against the end face of the plate.

[0015] Preferably, the handle is provided with a pull hole.

[0016] Preferably, both the handle and the cover are made of plastic.

[0017] Preferably, the end face of the cover plate facing the handle is provided with a circular groove, and the end face of the handle facing the cover plate is provided with a circular protrusion, and the circular groove and the circular protrusion engage after the cover plate slides.

[0018] Preferably, the circular protrusion is squeezed into the circular groove by plastic deformation and engages with the circular groove.

[0019] Compared to the aforementioned background technology, the board insertion / removal assistance structure of this application features a recessed groove on the handle. The recessed groove's outline shape is identical to that of the board. After engaging with the board, the groove limits five degrees of freedom of the board through the engagement part and the limiting plate. A cover plate, slidably connected to the handle, further limits the sixth degree of freedom, ensuring a stable engagement between the board and the handle. Furthermore, for situations where the server's depth, width, and height are severely limited in two directions, while the other direction has ample space, the handle of this application extends the length of the board in its insertion / removal direction while engaging with it. Therefore, regardless of whether space is limited in any dimension, the use of this insertion / removal assistance structure is not affected, improving the operability of the board insertion / removal.

[0020] Specifically, the handle of this structure has a recessed groove, and on both sides of the recessed groove and on the handle, there are opposing engaging parts. The card is placed in the recessed groove and engages with the handle through the engaging parts, achieving four degrees of freedom limitation for the card within its own plane. Additionally, a limiting plate corresponding to the engaging parts is provided on the end face of the handle, and the end face of the card abuts against the end face of the limiting plate, thereby achieving a fifth degree of freedom limitation for the card. A cover plate is provided on the end face of the handle away from the limiting plate. The slidable cover plate slides towards the card, and the slidable cover plate abuts against the end face of the card away from the limiting plate, thereby achieving a sixth degree of freedom limitation for the card. Finally, by extending the length of the handle in the insertion and removal direction of the card, the operability of the card is improved. This structure is simple, stable, reliable, and easy to operate. Of course, this application uses one type of card as an example, but is not limited to this type of card. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper," "lower," "front," and "rear" is based on the orientation or positional relationship shown in the accompanying drawings. It is used only for the convenience of describing this application and for simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] like Figures 1 to 3 As shown, in this embodiment, a board insertion / removal aid structure is provided. This structure includes a handle 1 that engages with the board 3 and extends the length of the board 3 in its insertion / removal direction. It should be noted that the board 3 is typically inserted into a slot. The insertion / removal direction refers to the direction of movement generated when the board 3 is vertically inserted into or vertically removed from the slot. The handle 1 extends the length of the board 3 in its insertion / removal direction; that is, the total length of the handle 1 after engaging with the board 3 is greater than the length of the board 3 itself. Furthermore, a recessed groove 15 is provided on the handle 1, which... Figure 1 It can be seen that the recessed groove 15 is used to place the board 3, and two locking parts 16 are provided on both sides of the recessed groove 15 and on the handle 1. The two locking parts 16 are respectively locked to the two sides of the board 3.

[0030] It should be noted that, in order to improve the stability of the board 3 within the recessed groove 15, the outline shape of the recessed groove 15 can be set to be the same as the outline shape of the upper part of the board 3, thereby ensuring a tight connection between the two. The snap-fit ​​part 16 can be set according to the actual outline shape of the board 3, but it is necessary to ensure that the snap-fit ​​part 16 can snap into the board 3 to limit the plane direction of the board 3. Specifically, the snap-fit ​​part 16 can limit the insertion and removal direction of the board 3 through the snap-fit ​​protrusions or grooves. In addition, the handles 1 on the left and right sides of the recessed groove 15 can limit the left and right directions of the board 3, thereby limiting the four degrees of freedom of the board 3.

[0031] Additionally, a limiting plate 14 corresponding to the position of the engaging part 16 is provided on the end face of the handle 1. The end face of the plate 3 abuts against the end face of the limiting plate 14. Specifically, the plate 3 located in the recessed groove 15, since both sides of the plate 3 are located within the engaging part 16 and engaged with it, allows the end face of the plate 3 located within the engaging part 16 to abut against the limiting plate 14, thereby limiting the fifth degree of freedom of the plate 3 through the limiting plate 14. In other words, the height of the limiting plate 14 needs to be higher than the plane where the handle 1 is located, and the end face of the limiting plate 14 abutting against the plate 3 is made so that the end face of the handle 1 is flush, ensuring that the plate 3 can be stably engaged with the handle 1. Of course, for the limiting of the plate 3, the engaging part 16 and the plate 3 do not need to be perfectly engaged; a certain amount of room for movement can be left, but it is necessary to ensure that the handle 1 does not detach from the plate 3. Similarly, the setting of the limiting plate 14 is also the same.

[0032] A slidable cover plate 2 is provided on the end face of the handle 1 away from the limiting plate 14. The slidable cover plate 2 can slide towards the plate 3. In this embodiment, the end face of the cover plate 2 is fitted with the end face of the handle 1. The slidable cover plate 2 can engage with the handle 1, and the engaged cover plate 2 is used to abut against the end face of the plate 3 away from the limiting plate 14. It should be noted that the fitted sliding arrangement of the cover plate 2 and the handle 1 is also to improve the stability of the plate 3 after it is limited. The end face of the cover plate 2 facing the handle 1 can be flush with the end face of the handle 1 facing the cover plate 2, thereby maximizing the restriction of the movement space of the plate 3 in the engaging part 16, thereby reducing the possibility of the plate 3 shaking.

[0033] It should be noted that the aforementioned design of the latching part 16, the limiting plate 14, and the cover plate 2 can all provide sufficient space for the movement of the card 3, thereby enhancing the adaptability of the structure to accommodate cards 3 of different thicknesses. However, it is necessary to ensure that the card 3 cannot detach from the reserved space. In other words, provided that the sliding cover plate 2 covers the latching part 16, a certain gap can be maintained between the cover plate 2 and the latching part 16. Since different types of cards 3 may have different thicknesses, sufficient space can be provided to accommodate various types of cards 3. Similarly, the limiting plate 14 can be designed in the same way. It is worth noting that the gap between the cover plate 2 and the latching part 16, and the gap between the limiting plate 14 and the latching part 16, should not be too large to accommodate cards 3 of smaller thicknesses. Of course, the thickness of the latching part 16 can also be increased to improve the applicability of the structure to cards 3 of different thicknesses. Naturally, in situations where operating space is limited, the design can be adjusted according to the actual situation, which will not be elaborated here.

[0034] The cover plate 2 and the limiting plate 14 are used together to limit the plate 3 and the handle 1 to be in the same plane. Here, "in the same plane" means that the plate 3 and the handle 1 partially or completely overlap in the thickness direction. The purpose here is to ensure that the plate 3 can be engaged with the locking part 16. At the same time, the limiting plate 14 limits the fifth degree of freedom of the plate 3, and the cover plate 2 limits the sixth degree of freedom of the plate 3, thereby completing the limitation of all six degrees of freedom of the plate 3.

[0035] In summary, the board 3 insertion / removal assistance structure of this application provides a recessed groove 15 on the handle 1, the outline of which is the same as that of the board 3. After engaging with the board 3, the locking part 16 and the limiting plate 14 limit the five degrees of freedom of the board 3, and the cover plate 2, which is slidably disposed with the handle 1, limits the sixth degree of freedom of the board 3, thereby ensuring a stable engagement between the board 3 and the handle 1. In addition, for situations where the space in two of the server's depth, width, and height directions is severely limited, while the space in the other direction is relatively abundant, the handle 1 of this application extends the length of the board 3 in its insertion / removal direction while engaging with the board 3. Therefore, regardless of whether the space is limited in any dimension, the use of the insertion / removal assistance structure is not affected, improving the operability of the board 3.

[0036] Specifically, the handle 1 of this structure is provided with a recessed groove 15, and on both sides of the recessed groove 15 and on the handle 1, there are opposing engaging parts 16. The plate 3 is placed in the recessed groove 15 and engages with the handle 1 through the engaging parts 16, thereby limiting the plate 3 to four degrees of freedom in its own plane. In addition, a limiting plate 14 corresponding to the position of the engaging part 16 is provided on the end face of the handle 1. The end face of the plate 3 abuts against the end face of the limiting plate 14, thereby limiting the plate 3 to the fifth degree of freedom. A cover plate 2 is provided on the end face of the handle 1 away from the limiting plate 14. The slidable cover plate 2 slides towards the plate 3, and the slid-out cover plate 2 abuts against the end face of the plate 3 away from the limiting plate 14, thereby limiting the plate 3 to the sixth degree of freedom. Finally, by extending the length of the handle 1 in the insertion and removal direction of the plate 3, the operability of the plate 3 is improved.

[0037] For the slidable cover plate 2, in this embodiment, two parallel elongated holes 11 are provided on the handle 1, which are consistent with the insertion and removal direction of the card 3. A limiting member corresponding to the position of the two elongated holes 11 is provided on the cover plate 2, and the limiting member is provided through the elongated hole 11. The limiting member is used to limit the cover plate 2 to slide only along the length direction of the elongated hole 11. It should be noted that in order to improve the stability of the cover plate 2 sliding relative to the handle 1, the two elongated holes 11 can be set separately on both sides of the handle 1, and there is a certain distance between the two elongated holes 11 to ensure the stability of the cover plate 2 sliding.

[0038] The aforementioned limiting component includes a limiting block 21 and a limiting ring 22. The limiting block 21 is located inside the elongated hole 11 and is slidably disposed with the elongated hole 11. A limiting ring 22 is disposed at the end of the limiting block 21 away from the cover plate 2. The limiting ring 22 abuts against the end face of the handle 1 away from the cover plate 2, and the diameter of the limiting ring 22 is greater than the width of the elongated hole 11, so as to limit the axial movement of the limiting block 21. This will not be described in detail here. For details, please refer to the limiting structure of the sliding block in the prior art.

[0039] It should be noted that, to facilitate the assembly and disassembly of the cover plate 2, an annular groove 12 is provided on the elongated hole 11 in this embodiment. The diameter of the annular groove 12 is larger than the diameter of the limiting ring 22. The limiting ring 22 can pass into the annular groove 12, and after passing into the annular groove 12, the limiting ring 22, after sliding with the sliding block, abuts against the end face of the handle 1 away from the cover plate 2, thereby realizing the detachable assembly and disassembly of the cover plate 2. Of course, the setting of the limiting ring 22 and the annular groove 12 is not limited to the above-mentioned circular structure; it can also be square or other structural forms, but it is necessary to ensure that the two match and can be detachably assembled.

[0040] In addition, in order to improve the sliding stability of the limiting block 21 in the elongated hole 11, the limiting block 21 can be set as an elongated shape that matches the elongated hole 11. The elongated shape has a certain length, and the two sides of the elongated shape can abut against and slide against the inner wall of the elongated hole 11, thereby increasing the possibility of the sliding block shaking in the elongated hole 11.

[0041] Additionally, the cover plate 2 can be configured as a U-shaped structure, with its two sides abutting against the end face of the card 3. In other words, the two sides of the U-shaped structure correspond to the position of the latching part 16, thus limiting the sixth degree of freedom of the card 3 located only within the latching part 16. Of course, the specific configuration of the cover plate 2 is not strictly limited here; the key is to ensure that it can limit the sixth degree of freedom of the card 3 without affecting the normal use of the structure.

[0042] Furthermore, a pull hole 13 can be provided on the handle 1 to facilitate the worker to pull out or insert the board 3; in addition, in order to prevent the structure from causing certain damage to the board 3, the handle 1 and the cover plate 2 can be made of plastic.

[0043] Based on the aforementioned plastic material, a circular groove 23 is provided on the end face of the cover plate 2 facing the handle 1, and a circular protrusion 17 is provided on the end face of the handle 1 facing the cover plate 2. The circular groove 23 engages with the circular protrusion 17 as the cover plate 2 slides. Specifically, during the sliding process of the cover plate 2 relative to the handle 1, the circular protrusion 17 undergoes plastic deformation. When the cover plate 2 slides to the appropriate position, the circular protrusion 17 is squeezed into the circular groove 23 through plastic deformation, thereby achieving the engagement between the cover plate 2 and the handle 1, serving as a limiting function and preventing relative displacement between the assembled handle 1 and the cover plate 2.

[0044] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0045] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
