[0024] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.
[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.
[0026] Example 1
[0027] This application provides a guiding structure, such as Figure 1 and Figure 2 As shown, it includes: a pair of first guide rails 1, which can be relatively disposed in the mounting space 2 in the electronic device housing 40, the distance between the pair of first guide rails 1 is adapted to the width of the first functional module 10 and the second functional module 20, and the pair of first guide rails 1 are respectively provided with a clearance area 101 at a preset position in a first direction extending along the first guide rail 1, the clearance area 101 is used to adapt the length of the first guide rail 1 to the length of the second functional module 20; and a first mounting module 3, which can be disposed in the mounting space 2 and slidably connected to the pair of first guide rails 1, for adjusting the distance between the first guide rails 1 to limit the displacement of a third functional module 30 of other sizes in the mounting space 2.
[0028] The guide structure provided in this application is applicable to electronic devices such as servers, computers, and communication equipment, and aims to solve the problem that traditional guide rails are difficult to adapt to functional modules of different specifications.
[0029] Within the mounting space 2 of the electronic device housing 40, a pair of first guide rails 1 are arranged opposite each other. One end of the housing 40 may have an opening to facilitate the installation of the first functional module 10, the second functional module 20, or the third functional module 30 into the mounting space 2. The distance between the first guide rails 1 is such that it can be adapted to the width dimensions of the first functional module 10 (e.g., a board of a specific specification) and the second functional module 20 (a board of another specification).
[0030] Simultaneously, clearance areas 101 can be set at preset positions along a first direction extending from the pair of first guide rails 1. For example, clearance areas 101 can be set in the middle or a specific length section of the first guide rail 1 in the direction extending from the opening of the housing 40 into the installation space 2. The setting of clearance areas 101 allows the first guide rail 1 to adapt to the length of the second functional module 20. When the length of the second functional module 20 is short, the setting of clearance areas 101 allows the second functional module 20 to be installed smoothly without interfering with the first guide rail 1.
[0031] The guiding structure also includes a first mounting module 3, which can be slidably connected to a pair of first guide rails 1 within the mounting space 2. This allows the mounting space 2 to accommodate third functional modules 30 of different sizes (other specifications of boards besides the first functional module 10 and the second functional module 20). For example, when a smaller third functional module 30 is installed in the mounting space 2, the first mounting module 3 can be assembled with the pair of first guide rails 1 firstly to adjust the distance between the first guide rails 1. In this case, the first guide rails 1 and the first mounting module 3 together restrict the displacement of the third functional module 30 within the mounting space 2, achieving stable installation of the third functional module 30.
[0032] The guide structure provided in this application embodiment, through the adjustable distance between a pair of first guide rails 1 and the setting of the avoidance area 101, enables the installation space 2 to adapt to a variety of functional modules of different specifications, realizing effective guidance and limiting of functional modules during insertion and removal operations, no longer limited to the installation of a certain type of board, avoiding the problem of redesigning the guide rail every time the board is replaced, greatly improving the flexibility in practical applications and reducing costs.
[0033] In some embodiments, the first guide rail 1 is arranged along the depth direction of the installation space 2, and the first guide rail 1 is provided with a first slide groove. The first functional module 10 can be slidably connected to the electronic device through the first slide groove. The first slide groove is used to limit the displacement of the first functional module 10 relative to the electronic device in the width and height directions of the installation space 2.
[0034] In the mounting space 2 within the electronic device housing 40, a first guide rail 1 is installed along the depth direction of the mounting space 2 (i.e., extending inward from the opening of the housing 40 to the interior). Taking a server chassis as an example, the server chassis has a certain depth space inside, and the first guide rail 1 is fixedly installed on the inner walls of both sides of the chassis along this depth direction, forming a pair of opposing guide rail structures.
[0035] A first groove is formed on the first guide rail 1. The shape and size of the first groove are designed according to the edge structure of the first functional module 10. For example, the first groove can be a recess with a specific width and depth, the width of which is slightly larger than the thickness of the edge of the first functional module 10, to ensure that the first functional module 10 can be smoothly inserted into the first groove.
[0036] The first slide provides a clear guide path for the installation of the first functional module 10. In the width direction of the installation space 2, the side walls of the first slide contact the edge of the first functional module 10, preventing it from swaying left and right. In the height direction of the installation space 2, the bottom and top surfaces of the first slide mate with the upper and lower surfaces of the edge of the first functional module 10, restricting its vertical movement. This limiting effect ensures that the first functional module 10 maintains a stable position within the installation space 2, guaranteeing its normal connection and collaborative operation with other components. The operator only needs to align the first functional module 10 with the first slide and push it in to ensure accurate installation of the first functional module 10 in the predetermined position, avoiding offset or misalignment during installation and improving installation accuracy and efficiency.
[0037] In some embodiments, such as Figure 1 As shown, the avoidance area 101 is disposed in the middle of the first guide rail 1 along the first direction of the first guide rail 1. The distance from the avoidance area 101 to one end of the first guide rail 1 is adapted to the length of the second functional module 20. The avoidance area 101 is used to avoid the connection position between the second functional module 20 and the electronic device.
[0038] A clearance area 101 is formed in the middle of the first guide rail 1, which is arranged along the depth direction inside the electronic device housing 40. Taking a server chassis as an example, the first guide rail 1 extends inward from the chassis opening, and the clearance area 101 is located at the middle position along the length direction of the first guide rail 1. The distance from the clearance area 101 to the end of the first guide rail 1 near the opening of the housing 40 is adapted to the length dimension of the second functional module 20. For example, if the length of the second functional module 20 is 117mm, then the starting position of the clearance area 101 is 117mm from the front end of the guide rail, ensuring that the rear connection position of the module is aligned with the clearance area 101.
[0039] By providing a clearance area 101 in the middle of the guide rail, the guide structure can simultaneously accommodate both the standard-length first functional module 10 and the shorter second functional module 20. For the second functional module 20, the clearance area 101 provides the space required for the connector, avoiding installation interference problems caused by insufficient module length, and significantly improving the versatility of the guide rail system.
[0040] In some embodiments, the avoidance area 101 is a groove structure provided on the first slide, and the groove structure is an arc-shaped groove.
[0041] An arc-shaped groove is machined along the width direction of the first guide rail 1 on the first slide groove of the first guide rail 1 as a clearance area 101. A pair of clearance areas 101 on the first guide rail 1 are arranged opposite to each other. The groove structure can be made into an arc-shaped groove, and the radius of the arc-shaped groove can be determined according to the external dimensions of the rear connector of the second functional module 20. The geometric characteristics of the arc-shaped groove allow it to adapt to connectors of various shapes, including circular, elliptical, or polygonal interfaces. At the same time, the arc-shaped groove forms a continuous curved transition on the guide rail body, avoiding scratches or jamming of the first functional module 10 during use that might occur due to right-angle edges.
[0042] In some embodiments, the first mounting module 3 can occupy part of the space in the height and width directions of the mounting space 2 so that the remaining height and width dimensions of the mounting space 2 are adapted to the height and width dimensions of the third functional module 30; the first mounting module 3 is a cuboid frame structure and can be detachably connected to one side wall of the mounting space 2.
[0043] The first mounting module 3 can be constructed by welding steel plates or beams to form a cuboid frame structure, or by using a one-piece molded plastic frame structure. Its external dimensions are manufactured according to the dimensions of the electronic device mounting space 2. The first mounting module 3 occupies part of the mounting space 2, allowing the remaining dimensions to be adapted to the third functional module 30. The first mounting module 3 can be detachably connected to one side wall of the mounting space 2, via quick-release clips or bolts. After the first mounting module 3 is slidably installed into the mounting space 2 along with a pair of first guide rails 1, it can be detachably connected to one side wall of the mounting space 2, fixing the first mounting module 3 within the mounting space 2. This allows the first mounting module 3 to provide comprehensive support and restraint for the third functional module 30.
[0044] By occupying part of the space with the first mounting module 3, the standard mounting space 2 can be converted into space suitable for the smaller third functional module 30, avoiding the cost of designing a separate chassis for the smaller module. Furthermore, since the first mounting module 3 is removable, when it is necessary to replace functional modules of different sizes, only the corresponding frame needs to be removed and replaced, without any modification to the chassis.
[0045] In some embodiments, such as Figure 2 As shown, the first mounting module 3 is provided with a accommodating space 301. The first mounting module 3 is also provided with a pair of second guide rails 302 located in the accommodating space 301. The second guide rails 302 are provided with second sliding grooves. The third functional module 30 can be slidably connected to the electronic device through the second sliding grooves of the pair of second guide rails 302. The second sliding grooves are used to limit the displacement of the third functional module 30 relative to the electronic device in the width and height directions of the third functional module 30.
[0046] The first mounting module 3 has a frame structure with a receiving space 301, the size of which is adapted to the third functional module 30. The first mounting module 3 includes a base plate. Inside the receiving space 301, a pair of second guide rails 302 are symmetrically mounted on the base plate, extending along the depth direction of the mounting space 2. Each second guide rail 302 has a second sliding groove, the openings of which face each other. The third functional module 30 can be slidably connected to the first mounting module 3 via the pair of second sliding grooves, thus being installed within the mounting space 2.
[0047] The second slide provides a clear guide path for the installation of the third functional module 30. In the width direction of the installation space 2, the two side walls of the second slide contact the edge of the third functional module 30 to prevent the third functional module 30 from swaying left and right; in the height direction of the installation space 2, the bottom and top surfaces of the second slide mate with the upper and lower surfaces of the edge of the third functional module 30 to restrict the vertical movement of the third functional module 30.
[0048] The first installation module 3 allows the smaller third functional module 30 to be stably inserted into the installation space 2. The operator only needs to align the third functional module 30 with the second slide and push it in to ensure that the third functional module 30 is accurately installed in the predetermined position, avoiding offset or misalignment during the installation process and improving the accuracy and efficiency of the installation.
[0049] In some embodiments, the first mounting module 3 is provided with a slider 303 on one side facing the first guide rail 1, and the first mounting module 3 is slidably connected to the first guide rail 1 through the slider 303.
[0050] On both sides of the first mounting module 3, i.e., on the side facing the first guide rail 1, sliders 303 are installed by injection molding or screw fixing. For example, the first mounting module 3 can be a cuboid frame structure, with a slider 303 installed at preset intervals along its length on its left and right side walls. The sliders 303 can be made of high-strength plastic material, and their bottoms can be designed with ball bearings to reduce friction during sliding.
[0051] When the third functional module 30 needs to be installed, the first mounting module 3 can be pushed so that its slider 303 slides smoothly in the first groove of the first guide rail 1. After the first mounting module 3 reaches the predetermined position, the first mounting module 3 is fixed to the housing 40 by the locking mechanism (such as screws, buckles, etc.) on the first mounting module 3.
[0052] The sliding connection method makes the installation and adjustment of the first mounting module 3 simple and convenient, requiring no professional tools or complicated installation procedures, thus reducing installation difficulty, installation time, and labor costs. At the same time, the guide rail and the first mounting module 3 can be reused, avoiding the increased costs caused by frequent guide rail replacements due to changes in functional module specifications.
[0053] In some embodiments, such as Figure 3 As shown, the guide structure also includes a second mounting module 4, which can occupy part of the space in the height direction of the mounting space 2 so that the remaining height dimension of the mounting space 2 is adapted to the height dimension of the second functional module 20.
[0054] The second mounting module 4 can adopt a frame structure made of high-strength alloy or steel, such as U-shaped, L-shaped, or square. Its horizontal width matches the width of the mounting space 2 within the electronic device, while the vertical height is designed according to the space required. The second mounting module 4 can be bolted to the top of the mounting space 2. To accommodate functional modules of different heights, the second mounting module 4 can be designed with a replaceable modular structure. Various frame structures with different vertical heights can be prepared according to actual needs. When a second functional module 20 of a different height needs to be installed, simply disassemble the original frame structure and replace it with a new frame structure of the corresponding height; no large-scale modification of the electronic device is required.
[0055] By occupying part of the space in the height direction by the second mounting module 4, the standard height mounting space 2 can be adjusted to a height suitable for a specific functional module, providing additional support and fixation for the functional module and avoiding the problem of module shaking due to excessive space.
[0056] In some embodiments, the second mounting module 4 is a cuboid frame structure that can be detachably connected to one side wall of the mounting space 2.
[0057] The second mounting module 4 can adopt a cuboid frame structure, assembled from high-strength alloy profiles or steel, with internal reinforcing ribs to enhance structural strength. The second mounting module 4 can be detachably connected to one side wall of the mounting space 2 via bolts, clips, or other connection methods. This detachable connection method makes disassembly and installation of the second mounting module 4 simple and convenient, requiring no complex tools. When it is necessary to replace functional modules of different heights or to maintain the second mounting module 4, disassembly and installation can be completed quickly, reducing maintenance time and labor costs.
[0058] Example 2
[0059] This application provides an electronic device, such as... Figures 4 to 6As shown, it includes: a first functional module 10, a second functional module 20, or a third functional module 30; a housing 40, which encloses an installation space 2 for placing the first functional module 10, the second functional module 20, or the third functional module 30; a guide structure, including a pair of first guide rails 1, which can be relatively disposed within the installation space 2 in the housing 40 of the electronic device, the distance between the pair of first guide rails 1 being adapted to the width of the first functional module 10 and the second functional module 20, and the pair of first guide rails 1 respectively having a clearance area 101 at a preset position in a first direction extending along the first guide rail 1, the clearance area 101 being used to allow the first guide rail 1 to adapt to the length of the second functional module 20; and a first mounting module 3, which can be disposed within the installation space 2 and slidably connected to the pair of first guide rails 1, for adjusting the distance between the first guide rails 1 to limit the displacement of the third functional module 30 of other sizes within the installation space 2.
[0060] The first functional module 10, the second functional module 20, and the third functional module 30 can be three different sizes of boards in a rack-mount server, with a pluggable structure for easy replacement and maintenance. For example, the dimensions of the first functional module 10 are 200mm long × 139mm wide × 37mm high, the dimensions of the second functional module 20 are 117mm long × 139mm wide × 15mm high, and the dimensions of the third functional module 30 are 117mm long × 76mm wide × 15mm high.
[0061] The housing 40 can be the outer shell of a chassis. Inside the housing 40 is an installation space 2. The depth and height dimensions of the installation space 2 are adapted to the length and height dimensions of the first functional module 10. The distance between a pair of first guide rails 1 within the installation space 2 is adapted to the width dimension of the first functional module 10, so that the first functional module 10 can be inserted into the installation space 2 via the pair of first guide rails 1.
[0062] In the middle of the first guide rail 1 along its extension direction, a clearance area 101 is set to accommodate the 117mm length of the second functional module 20. The length of this area is adapted to the length of the second functional module 20, i.e., 117mm. The clearance area 101 can adopt an arc-shaped groove structure to facilitate the installation of the rear connection position of the second functional module 20.
[0063] The first mounting module 3 can be a cuboid frame structure, with sliders 303 mounted on its two sides facing the first guide rail 1. When the third functional module 30 needs to be installed, the first mounting module 3 can be slidably connected to the first guide rail 1 via the sliders 303, and then the first mounting module 3 can be slid along the first guide rail 1. The space within the mounting space 2, excluding the first mounting module 3, forms a space suitable for the installation of the third functional module 30.
[0064] Through the first guide rail 1, the clearance area 101, and the slidable and adjustable first mounting module 3, the electronic device can accommodate three different specifications of circuit boards (first functional module 10, second functional module 20, and third functional module 30). Circuit boards of different widths, lengths, and heights can be installed without redesigning the guide rail, greatly improving the compatibility of the electronic device with different functional modules, meeting diverse usage needs, and allowing for flexible configuration of device functions in practical applications.
[0065] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
