Background

In the cloud domain, a server (server) plays a key role, which can provide and implement various cloud services required by network users, and with the advancement of science and technology, the server has been widely applied to different fields such as games, language processing, finance, biomedicine, search engines, electronic commerce, social network media, and the like.

In order to achieve the purposes of adaptability, compatibility, management convenience, cost saving and the like, the appearance size of most server cases adopts a universal industrial standard. The heights of industrial housings such as server housings are each based on the standard unit of U (1u =44.45mm =1.75 inches) in accordance with the specification set by the american Electronic Industry Association (EIA) as a standard. The number of server chassis commonly available in the market varies from 1U to 7U, depending on the actual needs of the user.

For a server chassis with a higher height, such as more than 4U, the side walls of the server chassis are more easily or have a higher probability of being inclined outward or turned outward due to the influence of the manufacturing process or internal elements, and in order to avoid this problem, a cross bar (bar) connecting the two opposite side walls is commonly found on the server chassis with a higher height, so as to avoid the occurrence of the condition that the side walls are inclined outward or turned outward by fixing the distance between the two side walls.

On the other hand, for similar reasons, the expansion module installed in the server chassis may also have a case that the housing is deformed or shifted, and for example, the housing of the PCIe expansion module is also generally a hollow box structure, so that after the expansion module is installed in the server chassis, an unsupported portion (e.g., a terminal) of the housing is easily deformed along with the increase of the number of the PCIe cards accommodated.

Therefore, it is necessary to consider the problem that the server chassis and the internal module case thereof are deformed.

Therefore, it is desirable to provide an electronic device and a fixing support assembly thereof to solve the above problems.

In the present embodiment, the fixed support assembly 1 may comprise a support body 100, a plurality of first engaging members 110, a plurality of second engaging members 120, and an actuating mechanism 130. Generally, the first engaging member 110, the second engaging member 120 and the actuating mechanism 130 are movably disposed on the supporting body 100, the first engaging member 110 and the second engaging member 120 are divided into two groups of members in a one-to-one matching manner, the two groups of members are disposed at two opposite ends of the supporting body 100, the actuating mechanism 130 can simultaneously link the two groups of first engaging members 110 and the two groups of second engaging members 120, so as to drive the first engaging member 110 and the second engaging member 120 of each group to engage with the adjacent chassis side wall 911 and the expansion unit housing 810, respectively. Since the two sets of the first engaging members 110 and the second engaging members 120 have substantially the same or similar configurations, for the sake of brief description, the fixed support assembly 1 will be described below by taking only the related contents of one set of the first engaging members 110 and the second engaging members 120 as an example.

In the present embodiment, the supporting body 100 is a portion of the fixing support assembly 1 that can cross over the chassis 910 to be fixed to the chassis side walls 911 on two opposite sides of the chassis 910 respectively. The support body 100 is defined as having a long axis direction LD, which is an extending direction of the long side of the support body 100. The hook structures 101 are respectively located at two opposite ends of the supporting body 100, and the hook structures 101 are in an inverted hook shape at the two opposite ends of the supporting body 100, and can be hung on the top edge of the case side wall 911. In addition, in the present embodiment, the supporting body 100 may further include a plurality of receiving spaces S, which are grooves formed at two opposite ends of the supporting body 100 and surrounded by the plate material. As shown in the figure, the accommodating spaces S are respectively adjacent to the hook structures 101.

The first engaging member 110 and the second engaging member 120 are slidably disposed on the supporting body 100, and both are accommodated in the accommodating space S. Moreover, the opposite sides of the first engaging member 110 are respectively connected to the actuating mechanism 130 and the second engaging member 120, so that the actuating mechanism 130 can drive the second engaging member 120.

In detail, in the present embodiment, the width of the first engaging member 110 is substantially equal to or slightly less than the width of the accommodating space S, and the inner wall surface of the accommodating space S formed by the first engaging member 110 and the supporting body 100 may be respectively provided with a sliding slot extending along the long axis direction LD and a guiding post slidably disposed on the sliding slot, so that when the first engaging member 110 is accommodated in the accommodating space S, the first engaging member 110 is guided or limited by the inner wall surface of the supporting body 100 and the sliding slot and the guiding post and can only be slidably disposed in the accommodating space S along the long axis direction LD. Herein, the first engaging member 110 can slide between a first engaging position (shown in fig. 5) and a first disengaging position (shown in fig. 8).

The partial structure of the first engaging member 110 can pass through the supporting body 100 to the outside of the accommodating space S. Therefore, in this embodiment, the support main body 100 may further include first through holes 104, the first through holes 104 are respectively communicated with one side of the accommodating space S facing the case side wall 911, the first engaging member 110 may include a positioning post 111, and the positioning post 111 is protruded from one side of the first engaging member 110 facing the case side wall 911 so as to penetrate through the first through holes 104 of the support main body 100.

In this embodiment, the fixing support assembly 1 may further include an elastic element 161, and the elastic element 161 may be a tension spring and may be engaged between the first engaging element 110 and the inner wall surface of the accommodating space S to provide an elastic restoring force so as to normally pull the first engaging element 110 toward one side of the accommodating space S where the first through hole 104 is formed, i.e., normally force the first engaging element 110 to slide from the first disengaging position to the first engaging position, so that the positioning pillar 111 of the first engaging element 110 protrudes from the first through hole 104 or protrudes out of the first through hole 104. However, the elastic member is not limited to be a tension spring, for example, in the fixing and supporting assembly of other embodiments, the elastic member between the first engaging member and the inner wall surface of the accommodating space may be a compression spring interposed between the other side of the first engaging member and the inner wall surface of the accommodating space, so as to normally push the first engaging member to the first engaging position.

The second engaging member 120 is slidably disposed on the supporting body 100, and the second engaging member 120 can be linked with the first engaging member 110. In detail, the supporting body 100 may further include a plurality of guiding elements 105, and the guiding elements 105 may be, but are not limited to, screws or bolts additionally screwed or riveted in the accommodating space S, or may be, but are not limited to, protruding structures integrally formed on the supporting body 100 and located in the accommodating space S. The second engaging member 120 is substantially plate-shaped and may have a plurality of assembling grooves 123, an extending direction of the assembling grooves 123 is substantially perpendicular to the long axis direction LD of the supporting body 100, and the guiding member 105 penetrates through the assembling grooves 123, so that the second engaging member 120 is guided or limited by the assembling grooves 123 and the guiding member 105 and can be slidably disposed in the accommodating space S only along a direction substantially perpendicular to the long axis direction LD. Here, the second engaging member 120 can slide between a second engaging position (shown in fig. 5) and a second disengaging position (shown in fig. 8).

The second engaging member 120 also has a partial structure capable of passing through the supporting body 100 to the outside of the accommodating space S. Therefore, in the embodiment, the supporting body 100 may further include second through holes 106, the second through holes 106 are respectively communicated with one side of the accommodating space S facing the expanding unit housing 810, and the second engaging member 120 may include a hook portion 121 so as to penetrate through the second through holes 106 of the supporting body 100.

In this embodiment, the fixing support assembly 1 may further include an elastic element 162, where the elastic element 162 may be an extension spring, and may be engaged between the second engaging element 120 and the inner wall surface of the accommodating space S to provide an elastic restoring force, so as to normally pull the second engaging element 120 toward the side of the accommodating space S where the second through hole 106 is formed, that is, normally force the second engaging element 120 to slide from the second disengaged position to the second engaging position, so that the hook portion 121 of the second engaging element 120 protrudes from the second through hole 106 or protrudes out of the second through hole 106. However, the elastic member is not limited to a tension spring, for example, in the fixing support assembly of other embodiments, the elastic member between the second engaging member and the inner wall surface of the accommodating space may be a compression spring interposed between the other side of the second engaging member and the inner wall surface of the accommodating space, so as to normally push the second engaging member to the second engaging position.

In the present embodiment, the second engaging member 120 is slidably interposed between the first engaging member 110 and the supporting body 100, in other words, the first engaging member 110 is slidably stacked on the second engaging member 120. Moreover, in order to couple the first engaging member 110 and the second engaging member 120, the first engaging member 110 is provided with a mounting protrusion 113 protruding toward the surface of the second engaging member 120, the second engaging member 120 further has a guiding groove 125, the extending direction of the guiding groove 125 forms an angle with the slidable direction of the second engaging member 120 (i.e. the direction perpendicular to the long axis direction LD of the supporting body 100) and the slidable direction of the first engaging member 110 (i.e. the long axis direction LD), and the mounting protrusion 113 is slidably disposed through the guiding groove 125. Thus, when the first engaging member 110 slides along the long axis direction LD, the second engaging member 120 can be driven to slide along the direction perpendicular to the long axis direction LD by the cooperation of the mounting protrusion 113 and the guiding groove 125. In other words, when the first engaging member 110 slides along the long axis direction LD between the first disengaging position and the first engaging position, the second engaging member 120 can be driven to slide along a direction perpendicular to the long axis direction LD between the second disengaging position and the second engaging position.

Specifically, in the present embodiment, when the first engaging element 110 slides from the first disengaging position to the first engaging position along the long axis direction LD so that the positioning post 111 protrudes out of or protrudes out of the first through hole 104 of the supporting body 100, the second engaging element 120 can be driven to slide from the second disengaging position to the second engaging position along the direction perpendicular to the long axis direction LD so that the engaging portion 121 protrudes out of or protrudes out of the second through hole 106 of the supporting body 100. Conversely, when the first engaging member 110 slides along the long axis direction LD from the first engaging position to the first disengaging position so that the positioning post 111 is retracted into or less protruded from the first through hole 104 of the supporting body 100, the second engaging member 120 can be driven to slide along the direction perpendicular to the long axis direction LD from the second engaging position to the second disengaging position so that the hook portion 121 is retracted into or less protruded from the second through hole 106 of the supporting body 100. That is, when the first engaging member 110 is located at the first disengaging position, the second engaging member 120 can be linked to be located at the second disengaging position, and when the first engaging member 110 is located at the first engaging position, the second engaging member 120 can be linked to be located at the second engaging position.

On the other hand, in order to enable the actuating mechanism 130 to couple the first engaging member 110, in the present embodiment, the actuating mechanism 130 may include an operating member 131, a plurality of rotating members 132 and a plurality of linking members 133, generally, the operating member 131 may be slidably disposed on the supporting body 100, and may be connected to the linking members 133 through the rotating members 132, and the linking members 133 may be slidably connected between the rotating members 132 and the first engaging member 110, so that the first engaging member 110 may be coupled to the linking members 133 through the rotating members 132 when the operating member 131 is actuated. Since the entire actuating mechanism 130 is substantially symmetrical, the actuating mechanism 130 will be described below only by taking the related contents of the rotating element 132 and the linking element 133 on one side of the actuating mechanism 130 and the connection relationship between the rotating element and the first engaging element 110 as examples.

In this embodiment, the supporting body 100 may further include a plurality of guiding elements 107, the guiding elements 107 may be, but are not limited to, screws or bolts additionally screwed or riveted on the supporting body 100, or may be, but are not limited to, protruding structures integrally formed on the supporting body 100, the operating element 131 may have a plurality of assembling slots 1311, an extending direction of the assembling slots 1311 is substantially perpendicular to the long axis direction LD of the supporting body 100, and the guiding elements 107 are disposed through the assembling slots 1311, so that the operating element 131 is guided or limited by the assembling slots 1311 and the guiding elements 107 and is slidably disposed on the supporting body 100 only along a direction substantially perpendicular to the long axis direction LD.

In this embodiment, the fixing support assembly 1 may further include a plurality of elastic members 163, and the elastic members 163 may be a compression spring and may be engaged between the operation member 131 and the support main body 100 to provide an elastic restoring force so as to normally push the operation member 131 in a direction away from the support main body 100, so that the operation member 131 is maintained in a state exposed in a through hole 108 of the support main body 100.

The rotating member 132 is rotatably disposed on the supporting body 100, and two opposite ends of the rotating member are respectively pivoted to the operating member 131 and the linking member 133, and can be movably connected to the first engaging member 110 through the linking member 133. Thus, when the operation element 131 is driven, the rotation element 132 is driven to rotate, so that the rotation element 132 drives the linking element 133, and the linking element 133 drives the first engaging element 110.

The linking member 133 is generally in a shape of a strip, and the extending direction thereof is substantially parallel to the long axis direction LD of the supporting body 100, and the linking member 133 is slidably disposed on the supporting body 100 and connected between the linking member 133 and the first engaging member 110. In detail, in the present embodiment, the supporting body 100 may further include a plurality of guiding elements 109, the guiding elements 109 may be, but are not limited to, screws or bolts additionally screwed or riveted on the supporting body 100, or may also be, but are not limited to, protruding structures integrally formed on the supporting body 100, the linking element 133 may have a plurality of assembling slots 1331, an extending direction of the assembling slots 1331 is substantially parallel to the long axis direction LD of the supporting body 100, and the guiding elements 109 are disposed through the assembling slots 1331. Thus, the linking member 133 is guided or limited by the assembling slot 1331 and the guiding member 109 and is slidably disposed on the supporting body 100 only along the direction of the long axis LD, so as to be slidable on the supporting body 100 along the long axis LD together with the first engaging member 110. In other words, when the driving linking member 133 moves, the first engaging member 110 is driven to move in the same direction. It should be understood that the linking member 133 can be regarded as an extension of the first engaging member 110, and therefore, in the fixed supporting component of other embodiments, the linking member can also be integrally formed with the first engaging member.

In addition, in the embodiment, the linking element 133 may further have a guiding slot 1332, an extending direction of the guiding slot 1332 forms an angle with a slidable direction of the operating element 131 (i.e. a direction perpendicular to the long axis direction LD) and a slidable direction of the linking element 133 (i.e. the long axis direction LD), and the end of the rotating element 132 may slidably penetrate through the guiding slot 1332, so that when the operating element 131 slides in the direction perpendicular to the long axis direction LD to drive the rotating element 132 to rotate, the rotating element 132 may drive the linking element 133 to slide in the long axis direction LD through cooperation between the end of the rotating element 132 and the guiding slot 1332, and further drive the first engaging element 110 to slide in the same direction.

Accordingly, with the arrangement of the first engaging member 110, the second engaging member 120, and the actuating mechanism 130, a user can actuate the first engaging member 110 and the second engaging member 120 to switch positions by only pressing the operating member 131 of the actuating mechanism 130.

Here, please continue fig. 1 and 5 to further refer to fig. 6 to 8 to describe the operation of the fixing support assembly 1, fig. 6 shows a partially enlarged top view schematic diagram of the fixing support assembly when assembled on the case according to an embodiment of the present invention, fig. 7 shows a partially enlarged three-dimensional schematic diagram of the fixing support assembly when assembled on the case according to an embodiment of the present invention, and fig. 8 shows an operation schematic diagram of the fixing support assembly when disassembled according to an embodiment of the present invention.

First, as shown in fig. 1 and fig. 5 to 7, the opposite ends of the fixed supporting component 1 can be respectively engaged with the top edges of the casing side walls 911 on the opposite sides of the casing 910 by the hook structures 101 of the supporting main body 100, so as to restrain the casing side walls 911 on the opposite sides, and prevent the casing side walls 911 from inclining outwards or turning outwards. Moreover, at this time, the first engaging member 110 may be located at the first engaging position, so that the positioning column 111 thereof penetrates through the supporting main body 100 and is disposed through the through hole 9111 of the case sidewall 911, so as to prevent the hook structure 101 from being separated from the case sidewall 911. Therefore, the opposite ends of the supporting body 100 can be stably fixed on the case 910 by inserting the positioning posts 111 of the first engaging member 110 into the case side walls 911.

Meanwhile, the first engaging member 110 can be linked with the second engaging member 120 to make the second engaging member 120 located at the second engaging position, so that the hook portion 121 of the second engaging member 120 passes through the supporting body 100 and is engaged with a fixed column P of the expansion unit housing 810 of the expansion unit 8. Therefore, the opposite ends of the supporting body 100 can support the expansion unit housing 810 by the hook portions 121 of the second engaging members 120, respectively.

Accordingly, by fixing the supporting component 1, the expansion unit housing 810 in the chassis 910 can be engaged while stably supporting and maintaining the relative position relationship of the chassis sidewall 911 of the chassis 910, so as to support the expansion unit housing 810 while preventing the chassis sidewall 911 from tilting outward or turning outward, thereby preventing the expansion unit housing 810 from deforming. That is, the utility model discloses fixed supporting component 1 of embodiment can reach fixed quick-witted case 910, support extension unit casing 810 simultaneously and prevent the quick-witted case 910 and the produced multiple effect of deformation of factors such as manufacturing process or self weight of extension unit casing 810.

When the fixing support assembly 1 is to be disassembled, only simple steps such as operating the operation member 131 of the actuating mechanism 130 are required. As shown in fig. 8, when the user presses the operating element 131 to slide the operating element 131 in a direction perpendicular to the long axis direction LD of the supporting body 100, the operating element 131 can rotate the rotating element 132, so that the rotating element 132 drives the linking element 133 and the first engaging element 110 connected to the linking element 133 to make the first engaging element 110 approach to the operating element 131 along the long axis direction LD, so that the first engaging element 110 slides to the first disengaging position to make the positioning column 111 retract into or protrude less from the supporting body 100, and meanwhile, the second engaging element 120 is linked by the first engaging element 110 to slide to the second disengaging position along the direction perpendicular to the long axis direction LD to make the engaging portion 121 retract into or protrude less from the supporting body 100. Thus, the positioning posts 111 of the first engaging member 110 can be separated from the through holes 9111 of the case sidewall 911, and the hook portions 121 of the second engaging member 120 can be separated from the fixing posts P of the extension unit housing 810. At this time, the supporting body 100 can be removed from the chassis 910 to complete the detachment of the fixing support assembly 1.

Therefore, the fixing and supporting assembly 1 not only has the functions of supporting and fixing the case side wall 911 and the extension unit housing 810, but also can be assembled and disassembled by only one hand in a single step without using additional tools, which is helpful for improving the efficiency of maintenance operation.

However, the aforementioned fixing support assembly 1 is only one exemplary embodiment of the present invention, and the present invention is not limited thereto. For example, referring to fig. 9 to 10, another embodiment of the present invention provides a fixing support assembly 1', which is also applicable to the aforementioned case 910 and the extension unit housing 810, and for the purpose of brief description, only the differences between the fixing support assembly 1' and the fixing support assembly 1 of the aforementioned embodiment will be described below, wherein like or same reference numerals will be used to refer to like or same elements, and the details of the like or same elements can be understood by referring to the aforementioned corresponding paragraphs, and will not be described again.
