Description

This disclosure relates to technology for mounting electronic devices on a rack.

Several electronic devices such as servers may be mounted together on a rack or the like. For example, Patent Document 1 discloses that electronic devices are mounted on a rack by supporting the sides of the electronic devices on mounting rails fixed to the rack posts.

Patent Document 2 also discloses a shelf into which multiple units can be inserted. At this time, the units are inserted into the shelf by fitting the rails of the units into rails that extend along the depth direction of the shelf.

JP 2020-150010 A Japanese Patent Application Publication No. 11-162560

The manager of the electronic devices and racks described above performs various management tasks, such as installing the racks and maintaining and replacing the electronic devices and various parts. During this time, electronic devices may be inserted or removed from the racks.

In the case of a rack structure such as that of Patent Document 1, various cables are directly connected to the back of the electronic devices mounted on the rack. Therefore, when inserting or removing an electronic device, the administrator must go to the back of the electronic device to insert or remove the various cables.

The shelf disclosed in Patent Document 2 has a connector attached to the backboard on the rear side of the shelf that mates with the connector of the unit. Therefore, when a unit is inserted into the shelf, the connector on the shelf mates with the connector on the unit. At this time, in order to mate the connectors, the shelf rails need to be installed at a fixed angle to the backboard. Therefore, for example, if the shelf rails are misaligned with the backboard, the connectors may not mate properly.

This disclosure was made in consideration of the above-mentioned problems, and one of its objectives is to provide a rack mounting structure etc. that can assist in management work related to racks that mount electronic devices.

The rack mounting structure according to one aspect of the present disclosure is a structure for mounting an electronic device on a rack, and includes a pair of guide members attached to both sides of the electronic device, a pair of rails fixed to the support columns of the rack along the insertion/removal direction of the electronic device relative to the rack and supporting each of the guide members from below so that they can move in the insertion/removal direction, and a power connector fixed to one end of at least one of the pair of rails and engaging with the power supply unit of the electronic device when the electronic device is inserted into the rack.

The rack according to one aspect of the present disclosure is a rack for mounting electronic devices, and includes a support pillar, a pair of rails fixed to the support pillar of the rack along the insertion/removal direction of the electronic device relative to the rack, supporting guide members attached to both sides of the electronic device from below so that the guide members are movable in the insertion/removal direction, and a power connector fixed to one end of at least one of the pair of rails and engaging with the power supply unit of the electronic device when the electronic device is inserted into the rack.

Embodiments of the present disclosure are described below with reference to the drawings.

First Embodiment
An overview of the rack mounting structure of the first embodiment will be described.

First, the rack 1 in this disclosure will be described. FIG. 1 is a perspective view showing an example of the rack 1. As shown in FIG. 1, the rack 1 includes a rail 20, a power connector 30, and a support 50. The rack 1 mounts electronic equipment 100.

Figure 2 is a perspective view showing an example of a rack mounting structure 1000. As shown in Figure 2, the rack mounting structure 1000 includes a guide member 10, rails 20, and a power connector 30. A pair of guide members 10 are attached to both side surfaces of the electronic device 100. The electronic device 100 is mounted on the rack by each of the guide members 10 being supported by the pair of rails 20. At this time, the power connector 30 engages with the power supply unit of the electronic device 100.

In this way, the rack mounting structure 1000 shows a structure for mounting at least one electronic device 100 on the rack 1. Note that, although the example in FIG. 1 shows the rack 1 mounting one electronic device 100, this is not limited to this example. For example, the rack 1 may include multiple pairs of rails 20 and power connectors 30. For example, multiple electronic devices 100 are mounted on the rack 1 by fixing the pairs to the support 50 so as to stack multiple layers.

Note that the electronic device 100 is, for example, a server device, but is not limited to this example. The electronic device 100 may be any type of communication device.

Next, the rack mounting structure 1000 will be described in detail. FIG. 3A is a first perspective view showing an example of a configuration including the rack mounting structure 1000. In the example of FIG. 3A, guide members 10-1 and 10-2 are attached to the side of the electronic device 100. In the following figures, for the sake of explanation, the reference symbols are distinguished for each configuration. For example, the guide member 10 is distinguished from the guide members 10-1 and 10-2. When the guide members 10-1 and 10-2 are not distinguished, they are simply referred to as the guide member 10. In addition, in this disclosure, as with the guide member 10, when the components marked with the reference symbols x-n (x and n are integers of 1 or more) are not distinguished from each other, the reference symbol given to the component is simply represented as x. For example, when the rails 20-1 and 20-2 are not distinguished from each other, they are referred to as the rail 20, and when the power connectors 30-1 and 30-2 are not distinguished from each other, they are referred to as the power connector 30.

In the example of FIG. 3A, rail 20-1 is fixed to posts 50-1 and 50-2, and rail 20-2 is fixed to posts 50-3 and 50-4. Note that, although four posts are used in the example of FIG. 3A, this is not limiting. It is sufficient that rail 20-1 and rail 20-2 are each fixed to one or more posts. There may also be five or more posts.

Power connector 30-1 is fixed to rail 20-1, and power connector 30-2 is fixed to rail 20-2. Power connector 30-1 is connected to power supply cable 40-1, and power connector 30-2 is connected to power supply cable 40-2. Note that in the example of FIG. 3A, two power connectors are used, but the power connectors are not limited to this example. For example, if electronic device 100 has one power supply unit, power connector 30 may be fixed to only one of rails 20 depending on the position of the power supply unit. In this way, the number of power connectors may vary depending on the number of power supply units of electronic device 100.

3A is defined as a view of the electronic device 100 as seen from the front side. In the example of FIG. 3A, the electronic device 100 is mounted on the rack 1 by being inserted in the direction of the arrow (towards the rear of the electronic device 100). At this time, the rail 20 movably supports the guide member 10. For example, the guide member 10 slides in the direction of the arrow while being supported from below by the rail 20, thereby inserting the electronic device 100 into the rack 1. The inserted electronic device 100 is removed from the rack 1 by being removed in the opposite direction of the arrow (towards the front of the electronic device 100). In this way, the rail 20 is fixed to the support 50 of the rack 1 along the insertion/removal direction of the electronic device 100 relative to the rack 1. The rail 20 supports each of the guide members 10 movably in the insertion/removal direction.

The power supply unit 35 is located on the rear surface of the electronic device 100. The power supply unit 35 fits into the power connector 30. More specifically, the power supply unit 35-1 fits into the power connector 30-1, and the power supply unit 35-2 fits into the power connector 30-2. This allows power to be supplied to the electronic device 100.

Figure 3B is a second perspective view showing an example of a configuration including the rack mounting structure 1000. More specifically, Figure 3B is a view of the electronic device 100 mounted on the rack 1, as seen from the rear side of the electronic device. As shown in Figure 3B, when the electronic device 100 is inserted into the rack 1, the power connector 30 fits into the power supply unit 35 of the electronic device 100.

The power connector 30 is fixed to one end of at least one of the pair of rails 20. For example, as shown in FIG. 3B, the power connector 30 is fixed to the end of the rail 20 on the rear side of the electronic device 100.

Thus, the rack mounting structure 1000 of the first embodiment is a structure for mounting the electronic device 100 on the rack 1, and includes a pair of guide members 10 attached to both sides of the electronic device 100. The rack mounting structure 1000 also includes rails that are fixed to the support posts 50 of the rack 1 along the insertion/removal direction of the electronic device 100 relative to the rack 1, and support each of the guide members 10 from below so that they can move in the insertion/removal direction. The rack mounting structure 1000 also includes a power connector that is fixed to one end of at least one of the pair of rails 20, and that engages with the power supply unit 35 of the electronic device 100 when the electronic device 100 is inserted into the rack 1.

This allows the administrator to insert and remove the electronic device 100 along the rail 20. Then, when the electronic device 100 is inserted into the rack 1, the power supply unit 35 of the electronic device 100 fits into the power connector 30 fixed to the rail 20. Therefore, the administrator does not necessarily need to move to the back of the electronic device 100 to connect the power supply unit 35 of the electronic device 100. Also, for example, no matter what angle the rail 20 is installed at relative to the support 50, the administrator can easily align and connect the power supply unit 35 and the power connector 30. In other words, the rack mounting structure 1000 of the first embodiment can support management work related to racks that mount electronic devices.

Second Embodiment
Next, a rack mounting structure according to a second embodiment will be described. In the second embodiment, a further example of the rack mounting structure 1000 described in the first embodiment will be described.

Figure 4 is a first perspective view showing an example of a configuration including a rack mounting structure 1000 of the second embodiment. The rack mounting structure 1000 of the second embodiment includes a guide member 10, a rail 20, a power connector 30, a support 50, and a fixing member 60. The rack 1 also includes a rail 20, a power connector 30, and a support 50.

As shown in FIG. 4, there are a pair of guide members 10. The guide members 10 are attached to both side surfaces of the electronic device 100. Here, the surface of the electronic device 100 in the -y-axis direction is referred to as the front surface, and the surface in the +y-axis direction is referred to as the back surface. The surface of the electronic device 100 in the +x-axis direction is referred to as the right side surface, and the surface in the -x-axis direction is referred to as the left side surface. For example, guide member 10-1 is attached to the left side surface of the electronic device 100, and guide member 10-2 is attached to the right side surface of the electronic device 100. Each of the guide members 10 is fixed to the side surface of the electronic device 100 with a screw or the like.

In the example of FIG. 4, rail 20-1 is fixed to posts 50-1 and 50-2, and rail 20-2 is fixed to posts 50-3 and 50-4. In this way, a pair of rails 20 exists. Each of the rails 20 movably supports each of the guide members 10. For example, the electronic device 100 is inserted into the rack 1 by the guide member 10 sliding in the +y-axis direction while being supported by the rail 20.

An example of the support structure of the guide member 10 by the rail 20 will be described. FIG. 5 is a diagram showing an example of the support structure. Specifically, FIG. 5 is a cross-sectional view along the x-axis direction showing a part of the rail 20 and the guide member 10 when the electronic device 100 is mounted on the rack 1. In the example of FIG. 5, the guide member 10-2 and the rail 20-2 attached to the right side surface of the electronic device 100 are shown. The rail 20 has a guide structure. In the example of FIG. 5, the rail 20-2 is formed with a support portion and a movement limiting portion as an example of the guide structure. The support portion and the movement limiting portion are formed on the rail 20-2 along the y-axis direction. The support portion supports the guide member 10 from below. In addition, the movement limiting portion faces the upper surface of the support portion and limits the upward movement of the guide member 10.
For example, the guide member 10 has a protrusion formed along the y-axis direction. In the example of Fig. 5, the guide member 10-2 has a protrusion that protrudes in the +x-axis direction. At this time, the protrusion of the guide member 10 is inserted between the support portion and the movement limiting portion. At this time, the guide member 10 is supported by the support portion of the rail 20-2.

In this way, the rail 20 includes a guide structure. The guide structure has a support portion that supports the guide member from below along the insertion/removal direction, and a movement limiting portion that faces the upper surface of the support portion and limits the upward movement of the guide member.

As a result, the administrator can use the guide structure to move the electronic device 100, making it easy to correct the position of the electronic device 100. In addition, the movement limiting section limits the upward movement of the guide member 10 (in the +z-axis direction). Therefore, the rack mounting structure 1000 can reduce the possibility that the guide member 10 will come off the rail 20 and the electronic device 100 will fall.

Figure 6 is a second perspective view showing an example of a configuration including the rack mounting structure 1000 of the second embodiment. Figure 6 shows the rack mounting structure 1000 when the electronic device 100 is inserted into the rack 1. When the electronic device 100 is inserted as shown in Figure 6, the power connector 30 fixed to the rail 20 fits into the power supply unit 35 of the electronic device 100.

At this time, the power connector 30 may have a floating structure. FIG. 7 is a diagram illustrating an example of a floating structure. FIG. 7 shows the power supply unit 35 and the power connector 30 as viewed from the +z axis direction. When the power supply unit 35 and the power connector 30 are mated, the mating axes of the power supply unit 35 and the power connector 30 must match. In the example of FIG. 7, there is a misalignment between the mating axis A of the power supply unit 35 and the mating axis B of the power connector 30. The floating structure is a structure that moves to eliminate the misalignment when mating is performed in a situation where there is a misalignment. In the example of FIG. 7, pressure is applied to the power connector 30 from the power supply unit 35 when mating. Then, the power connector 30 moves in a direction (-x axis direction) in which the mating axis B approaches the mating axis A by a spring or the like.

In this way, the power connector 30 has a structure that allows it to move in a direction in which the mating axis of the power connector 30 coincides with the mating axis of the power supply unit 35. This allows it to absorb any misalignment in the mating axes of the power supply unit 35 and the power connector 30.

The fixing member 60 fixes the electronic device 100 to the rack 1. More specifically, after the electronic device 100 is inserted into the rack 1, the fixing member 60 is adjusted to fix the electronic device 100 to the rack 1.

Figure 8 is a diagram illustrating an example of the mechanism of the fixing member 60. Specifically, Figure 8 is a diagram illustrating the fixing member 60-1 on the left side of the electronic device 100 as viewed from the +z axis direction. The fixing member 60-1 has a screw head 61-1, a screw portion 62-1, and a mounting member 63-1. The mounting member 63-1 is attached to the electronic device 100. The screw head 61-1 is connected to one end of the screw portion 62-1. The screw portion 62-1 penetrates the mounting member 63-1. When the electronic device 100 is inserted into the rack 1, the screw portion 62-1 is inserted into a screw hole provided in the rail 20-1. For example, the administrator rotates the screw head 61-1 to insert the screw portion 62-1 into the screw hole in the +y axis direction. This causes the fixing member 60-1 to engage with the rail 20-1. In other words, the electronic device 100 is fixed to the rack 1. Similarly, the fixing member 60-2 has a screw head 61-2, a threaded portion 62-2, and an attachment member 63-2.

However, this is not limiting, and the fixing member 60 may be structured to engage with the support 50.

In this way, the fixing member 60 is a member that is attached to the electronic device 100, and fixes the electronic device 100 to at least one of the rail 20 and the support 50 when the electronic device 100 is inserted into the rack 1. This allows the rack mounting structure 1000 to fix the inserted electronic device 100 to the rack 1.

The screw head 61 of the fixing member 60 may be formed with a drive portion, which is a hole for inserting a screwdriver or the like. The screw head 61 may also be formed with a handle. For example, the screw head 61 may be formed with unevenness that fits the fingers. This allows the administrator to rotate the screw head 61 by hand, so that when inserting or removing the electronic device 100, the administrator can release and set the fixation by the fixing member 60 without using a tool such as a screwdriver.

The rail 20 has an adjustment mechanism 210. The adjustment mechanism 210 is a mechanism that can adjust the engagement position of the support 50 relative to the rail 20 according to the distance between the support posts 50. In this case, each of the rails 20 is fixed by multiple support posts 50. For example, the rail 20-2 is fixed by support posts 50-3 and 50-4. In this example, the adjustment mechanism 210 can adjust the engagement position of the support post 50-4 relative to the rail 20-2 according to the distance between the support posts 50-3 and 50-4.

FIG. 9 is a first diagram illustrating an example of the adjustment mechanism 210. Specifically, FIG. 9 is a diagram of the rail 20-2 as viewed from the +x-axis direction. In the example of FIG. 9, the rail 20-2 has an adjustment mechanism 210-2 and locking portions 211-2, 212-2, 213-2, and 214-2. The adjustment mechanism 210-2 also has long holes 215-2 and 216-2 and a movable member 217-2. The movable member 217-2 has a locking portion 218-2. The long holes 215-2 and 216-2 are holes that extend in the longitudinal direction of the rail 20-2. That is, the longitudinal direction of the long holes 215-2 and 216-2 is approximately the same as the longitudinal direction of the rail 20-2. The movable member 217-2 is locked to at least one of the long holes 215-2 and 216-2 by a screw or the like. The method of attaching the movable member 217 to the rail 20 is not limited to this example.

Similar to rail 20-2 described here, rail 20-1 has adjustment mechanism 210-1 and locking portions 211-1, 212-1, 213-1, and 214-1. Adjustment mechanism 210-1 also has long holes 215-1 and 216-1 and movable member 217-1. Movable member 217-1 has locking portion 218-1.

For example, the support 50-3 is engaged at one of the engagement portions 211-2, 212-2, 213-2, and 214-2. The engagement portion is, for example, a screw hole. The support 50-3 is engaged with the rail 20-1 by a screw or the like, using the engagement portion. In this way, the rail 20 may have multiple engagement portions. This allows the position of the rail 20 to be adjusted according to the position of the support 50.

For example, the support 50-4 is locked by a screw or the like at the locking portion 218-2 of the movable member 217-2. The movable member 217 is movable within the range of the long holes 215 and 216. The movable member 217-2 may have multiple locking portions. In other words, the adjustment mechanism 210 can be said to be a mechanism that can move at least one locking portion that can be locked with the support 50 in the longitudinal direction of the rail 20.

The movable member 217 is attached to the rail 20 using the long holes 215 and 216. For example, as described above, the movable member 217 may be locked to at least one of the long holes 215 and 216 by a screw. In the example of FIG. 4, the movable member 217 is locked by inserting a screw into both the long holes 215 and 216. However, the method of attaching the movable member 217 to the rail 20 is not limited to this example. FIG. 10 is a second diagram illustrating an example of the adjustment mechanism 210. Specifically, FIG. 10 is a cross-sectional view of the rail 20-2 and the adjustment mechanism 210-2 as viewed from the -y axis direction. In this example, the movable member 217-2 of the adjustment mechanism 210-2 forms a hook-shaped hook portion in the -x axis direction. The hook portion is inserted into each of the long holes 215-2 and 216-2. As shown in FIG. 10, the hooks are bent in the short direction of the long holes 215-2 and 216-2. This connects the rail 20-2 and the movable member 217-2.

Note that the movable member 217 and the long holes 215, 216 are not limited to this example. For example, there may be one or more long holes. There may be at least one hook portion of the movable member 217, and the number of hook portions may correspond to the number of long holes.

Then, the screw inserted into the support 50-4 is inserted into the locking portion 218-2, so that the support 50-4 locks with the movable member 217-2.

In this way, the rail 20 has multiple locking parts that can be locked to the support posts 50, and an adjustment mechanism 210. The adjustment mechanism 210 is a mechanism that can move at least one locking part that can be locked to the support posts 50 in the longitudinal direction of the rail 20. Here, the adjustment mechanism 210 may have an elongated hole provided in the rail 20, and a movable member 217. In this case, the longitudinal direction of the elongated hole may be the longitudinal direction of the rail 20. The movable member 217 may have at least one locking part and a hook-shaped hook that is inserted into the elongated hole and has a tip that is bent in the lateral direction of the elongated hole.

This allows the position at which the rail 20 is fixed to be adjusted according to the distance between the posts 50.

As described above, the rack mounting structure 1000 of the second embodiment is a structure for mounting the electronic device 100 on the rack 1, and includes a guide member 10 attached to the electronic device 100. The rack mounting structure 1000 also includes a rail 20 that is fixed to the support 50 of the rack 1 along the insertion/removal direction of the electronic device 100 relative to the rack 1 and supports the guide member 10 so that it can move in the insertion/removal direction. The rack mounting structure 1000 also includes a power connector 30 that is fixed to one end of the rail 20 and engages with the power supply unit 35 of the electronic device 100 when the electronic device 100 is inserted into the rack 1.

The rack 1 of the second embodiment is a rack on which electronic device 100 is mounted, and includes a support 50 and a rail 20 that is fixed to the support along the insertion/removal direction of electronic device 100 relative to the rack and supports guide member 10 provided on electronic device 100 so that the guide member 10 can move in the insertion/removal direction. The rack 1 includes a power connector 30 that is fixed to one end of the rail and engages with power supply unit 35 of electronic device 100 when electronic device 100 is inserted into the rack.

This allows the administrator to insert and remove the electronic device 100 along the rail 20. When the electronic device 100 is inserted into the rack 1, the power supply unit 35 of the electronic device 100 fits into the power connector 30 fixed to the rail 20. Therefore, the administrator does not necessarily need to move to the back of the electronic device 100 to connect the power supply unit 35 of the electronic device 100. Also, for example, no matter what angle the rail 20 is installed at relative to the support 50, the administrator can easily align and connect the power supply unit 35 and the power connector 30. In other words, the rack mounting structure 1000 of the second embodiment can support management work related to racks that mount electronic devices.

[Modification 1]
The support structure of the guide member 10 by the rail 20 is not limited to the example in FIG. 5. Specifically, the rail 20 may have a plurality of grooves. For example, in the rail 20-2 in FIG. 5, one or more guide structures may be further formed in the +z-axis direction of the guide structure. In this case, the rail 20-2 supports the guide member 10-2 by inserting a protrusion into any one of the plurality of grooves. This makes it possible to adjust the height of the electronic device 100 on a set of rails.

In addition, if the rail 20 has multiple grooves, the guide member 10 may have multiple protrusions that can be inserted into each of the multiple grooves. In this case, the rail 20 supports the guide member 10 by inserting the protrusions into each of the multiple grooves. As a result, the guide member 10 is supported by the multiple protrusions, allowing the electronic device 100 to be stably mounted.

The protrusion of the guide member 10 may be a roller. For example, the roller rotates to engage with the groove of the guide structure in the z-axis direction, causing the guide member 10 to slide.

[Modification 2]
In the above example, the fixing member 60 fixes the electronic device 100 in the insertion direction relative to the rack 1. The fixing member 60 is not limited to this example.

Figure 11 is a diagram illustrating an example of the mechanism of the fixing member 60 of the second modified example. Figure 11 differs from Figure 8 in the fixing direction of the fixing member 60-1. In the example of Figure 11, the screw portion 62-1 is locked by being inserted into the screw hole in the +x-axis direction.

The present invention has been described above with reference to the embodiments, but the present invention is not limited to the above embodiments. Various modifications that can be understood by a person skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
