Description

Technical Field

[0001] This utility model belongs to the field of chassis technology, and specifically relates to a mechanical compensation cover and a chassis equipped with the cover. Background Technology

[0002] As computer chassis have evolved, their internal structures have become increasingly complex. When chassis modules are blind-molded, manufacturing tolerances can lead to misalignment of functional boards and connectors on the backplane. Please refer to... Figure 1 In standard operation, a compensating pad 19 is placed on the cover plate to press the function board together, ensuring that the function board and the backplane connector are properly inserted.

[0003] However, the compensating gaskets for this type of pressing function board are directly glued to the cover plate during installation. These glued gaskets are prone to aging and reduced clamping force over long-term use, affecting product reliability. Furthermore, the compensating gaskets are generally made of rubber, which can be susceptible to unreliable adhesion, leading to gasket detachment. Detached rubber gaskets leave behind debris within the equipment, requiring multiple maintenance checks throughout the equipment's lifespan. Utility Model Content

A gap is also provided between the first limiting boss and the second limiting boss to allow the first movable slider to move in a direction perpendicular to the cover plate, and the second limiting boss and the first limiting boss are restricted in moving in a direction perpendicular to the cover plate by the movable gap.

[0010] As a further improvement to the above technical solution, chamfers are also provided at the corners where the first and second movable sliders form an acute angle.

[0011] As a further improvement to the above technical solution, the power structure consists of a through hole on the third moving slider, a threaded hole on the slide rail, and a screw that mates with the threaded hole.

[0029] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0031] Reference Figure 2 , Figure 3 A mechanical compensation cover plate 1 includes several slide rails 2 disposed on the cover plate 1. Each slide rail 2 has a fixed slider 3 and a third movable slider 6 disposed at both ends. The fixed slider 3 and the third movable slider 6 are disposed opposite each other at both ends of the slide rail 2, and the third movable slider 6 is movable at the end of the slide rail 2 via a power structure 7. A first movable slider 4 and a second movable slider 5 are also disposed on the slide rail 2 between the fixed slider 3 and the third movable slider 6. In this embodiment, at least two first movable sliders 4 are disposed, and the second movable slider 5 is disposed between two adjacent first movable sliders 4. Adjacent sliders are in wedge-face sliding contact. Specifically, the end faces of the first movable slider 4 and the second movable slider 5 that contact each other are respectively set as wedge surfaces. The end faces of the fixed slider 3 and the first movable slider 4 that contact each other, and the surfaces of the third movable slider 6 and the first movable slider 4 that contact each other are also wedge surfaces. When wedge-face contact is used, the acute-angled surface pushes the obtuse-angled surface to slide along the wedge surface, causing the structure with the obtuse-angled surface to move in a direction perpendicular to the slide rail. In this application, the direction in which the movable slider slides along the slide rail 2 toward the fixed slider 3 is defined as forward, and the opposite direction is backward. The direction in which the movable slider moves perpendicular to the cover plate 1 and away from the cover plate 1 is defined as upward, and the opposite direction is downward.

[0032] Reference Figure 3In this embodiment, the first movable slider 4, the second movable slider 5, and the third movable slider 6 are all movable sliders that can slide on the slide rail 2. When the third movable slider 6, located at the end, is pushed by the power structure 7, it slides forward along the slide rail 2, pushing the first movable slider 4, which is in contact with its wedge surface, and it moves upward while sliding along the slide rail 2. The sliding of the first movable slider 4 provides a thrust to the second movable slider 5. The second movable slider 5 pushes the next first movable slider 4, which is in contact with its wedge surface, and at the same time, it provides a reverse force to the previous first movable slider 4 due to the wedge surface contact. The two forces along the slide rail 2 and in opposite directions cancel each other out, so the previous first movable slider 4 only moves upward. The next first movable slider 4 pushed by the second movable slider 5 also moves along the wedge surface due to the thrust. In this way, as long as sufficient thrust is applied, multiple first movable sliders 4 and second movable sliders 5 can be set. The wedge surface of the last first movable slider 4 is in contact with the wedge surface on the fixed slider 3. The fixed slider 3 can only provide a reverse thrust to the first movable slider 4 and no longer pushes the next first movable slider 4. This structure, which relies entirely on the wedge-shaped contact between different sliders to move the first moving slider 4 up and down, achieves the compensation and support process for the functional boards inside the chassis through a purely mechanical means. Compared to the support of the compensation pad 19, which is glued to the cover plate 1, this method not only avoids the aging and detachment of the pad after long-term use, but also allows for the use of metal materials to support the mechanical structure of this invention. This further increases the lifespan of the mechanical compensation structure and enhances its long-term reliability.

[0033] Reference Figure 5 , Figure 6 In this embodiment, to minimize the thrust required between the support structure and the second movable slider 5, while ensuring stability during the wedge-shaped sliding process between the first movable slider 4 and the second movable slider 5, both the first movable slider 4 and the second movable slider 5 positioned between the two sets of first movable slider 4 are arranged in an isosceles trapezoidal shape. The isosceles trapezoidal first movable slider 4 and the second movable slider 5 are arranged in opposite directions perpendicular to the cover plate 1. The two sets of inclined sides on the isosceles trapezoidal first movable slider 4 and the second movable slider 5 have the same inclination angle, and the two sets of inclined sides with the same inclination angle slide in contact respectively. When this wedge-shaped surface with identical angles on both sides is subjected to force, it can generate the same magnitude of thrust on both sides of the first movable slider 4 simultaneously, ensuring the stability of the first movable slider 4 during upward movement. Furthermore, the smaller thrust simplifies the installation process and makes it more convenient and quick to use.

[0034] Reference Figure 7In this embodiment, the fixed slider 3 and the third movable slider 6 are arranged in a right-angled trapezoid, and the inclined side of the right-angled trapezoid has the same angle as the hypotenuse of the adjacent first movable slider 4. The right-angled sides of the fixed slider 3 and the third movable slider 6 are located on the outermost sides at both ends of the slide rail 2, and the two hypotenuses on the fixed slider 3 and the third movable slider 6 contact the hypotenuses of the two adjacent first movable sliders 4, pushing the adjacent first movable sliders 4. The same wedge angle ensures that the first movable slider 4 is subjected to the same force, and also ensures the stability of the first movable slider 4 during upward movement. Moreover, the smaller thrust simplifies the installation process and makes it more convenient and quick to use.

[0035] As one embodiment of this application, the contact position between the movable slider and the slide rail 2 is provided with a slide rail 8 that cooperates with the slide rail 2. The slide rail 8 cooperates with the slide rail 2 and is restricted on the slide rail 2 while realizing sliding, thus avoiding the separation of the two adjacent wedge surfaces due to excessive thrust of the power structure 7.

[0036] Reference Figure 4-7 Specifically, the slide rail 2 includes an elongated main body mounted on the cover plate 1 and first limiting bosses 9 protruding from both sides of the top of the main body; the movable slider is provided with a slide rail 8 extending in the front-back direction, and the two sides of the movable slider that contact the cover plate 1 are also provided with second limiting bosses 11 extending into the slide rail. The difference is that a gap is provided between the first limiting bosses 9 and the second limiting bosses 11, allowing the first movable slider 4 to move in a direction perpendicular to the cover plate, and the second limiting bosses 11 and the first limiting bosses 9 have a blocking function to limit the extreme position of the movable slider moving in a direction perpendicular to the cover plate 1. This movable gap setting allows the movable slider to slide on the slide rail 2 via the slide rail 8 while also moving within the movable gap range in a direction perpendicular to the cover plate 1. This achieves height adjustment of the first movable slider 4 perpendicular to the cover plate 1, allowing it to be used in chassis with different compensation requirements. It can also be used to adjust the compensation height when the modules inside the chassis become loose due to prolonged use in the same chassis, increasing the product's applicability while ensuring the performance.

[0037] Furthermore, during the sliding process of two adjacent wedge surfaces, due to the movable gap between the moving slider and the slide rail 2, uneven force can easily cause an angular shift between them, resulting in the acute angle directly contacting the opposing wedge surface and causing structural jamming. Therefore, a chamfer 10 is provided at the acute angle corner of the first moving slider 4 and the second moving slider 5. The chamfer 10 can produce a certain angle change when in contact with the opposing wedge surface, thereby adjusting the angle of the moving slider during contact and ensuring smooth operation of the overall structure. The chamfer 10 can be set as an angled corner or a rounded corner.

[0038] In one embodiment of this utility model, the power structure 7 comprises a through hole 12 on the third movable slider 6, a threaded hole 13 on the slide rail 2, and a screw 14 that engages with the threaded hole 13. When the screw 14 is used, a contact portion 15 is also provided on the rear side of the third movable slider 6. The contact portion 15 does not contain a slide rail 8. The through hole 12 penetrates the contact portion 15 in the front-to-back direction. The screw 14 passes through the through hole 12 on the contact portion 15 and is threadedly connected to the threaded hole 13 on the slide rail 2. When the screw 14 is inserted into the third movable slider 6, the head of the screw 14 abuts against the contact portion 15, and the tail of the screw 14 passes through the contact portion 15 and is threadedly connected to the slide rail 2. Thus, when the screw 14 is rotated, the tail of the screw 14 is screwed into the threaded hole, causing the head of the screw 14 to push the contact portion 15 closer to the end of the slide rail 2, thereby realizing the forward movement of the third movable slider 6 on the slide rail 2 and thus achieving the upward adjustment of the first movable slider 4. Conversely, when the screw 14 is rotated in the opposite direction, a gap is created between the head of the screw 14 and the abutment part 15, and it abuts against the function board. The first movable slider 4, which supports the function board, loses the pushing force of the third movable slider 6. The first movable slider 4 rebounds due to the loss of the reverse force when it abuts against the function board, and there is a gap fit between it and the function board, which can realize the easy disassembly of the mechanical compensation cover.

[0039] Reference Figure 2 When the mechanical compensation cover 1 is used inside the chassis, it also includes a chassis frame 16, a back plate 17, and a sub-plate 18. The sub-plate 18 is a functional board. The back plate 17 is set inside the chassis frame 16 and is parallel to one side of the chassis frame 16. The sub-plate 18 is vertically inserted into the back plate 17. The mechanical compensation cover is set on the chassis frame 16, which is parallel to the back plate 17, and the first movable slider 4 abuts against the sub-plate 18. In use, the back plate 17 is first installed into the chassis frame 16, and then the sub-plate 18 is inserted into the back plate 17. After insertion, the mechanical compensation cover 1, consisting of the compensation mechanism and the cover plate 1, is fastened to the corresponding position in the chassis. The screws 14 on the mechanical compensation mechanism are tightened, and the first movable slider moves along the insertion direction and generates pressure to ensure that the sub-plate 18 and the back plate 17 are fully inserted. Furthermore, the chassis frame 16 is provided with an adjustment hole 1601 for a force-applying tool to pass through and drive the screw to rotate.

[0040] In another embodiment of this utility model, a fixed slider 3 and a third movable slider 6 are respectively provided at both ends of a slide rail 2, and only a first movable slider 4 is provided between the fixed slider 3 and the third movable slider 6. The first movable slider 4 is arranged in an isosceles trapezoid, and both ends of the first movable slider 4 are connected to the fixed slider 3 and the third movable slider 6 by wedge surfaces. In this embodiment, the fixed slider 3 and the third movable slider 6 are arranged in a right-angled trapezoid, and the inclined side of the right-angled trapezoid has the same angle as the hypotenuse of the adjacent first movable slider 4. The outermost right-angled side of the fixed slider 3 and the third movable slider 6 is located in the front-back direction, and the two hypotenuses on the fixed slider 3 and the third movable slider 6 contact the two hypotenuses of the middle first movable slider 4, pushing the adjacent first movable slider 4. When only one first movable slider 4 is provided between the fixed slider 3 and the third movable slider 6 in this embodiment, the length of the first movable slider 4 can be set according to the position of the sub-plate 18 that needs to be supported in the chassis. This structure has fewer contact surfaces during use, resulting in less friction. Therefore, it is easier to use and install, and the fewer contact surfaces also make the overall structure more stable.

[0041] The above description is merely a preferred embodiment of this utility model. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments without departing from the technical scope of this utility model and based on its technical essence shall still fall within the scope of this utility model.
