Description

Node sliding parts

This model generally relates to a latch system for sliding parts of a node, and more specifically, to a handle latch mechanism (lever-latch mechanism). The handle latch mechanism provides a firmer connection with the electronic chassis and uses less The space is used to allow more airflow through the node sliding parts.

Computer housings and other types of electronic equipment are usually assembled in a vertical rack structure. There are multiple cabinets in each rack structure, and the cabinets contain electronic equipment. This assembly technique is often referred to as "rack assembly" and is often used with, for example, server-type computers. A typical data center may have thousands of rack structures.

The electronic equipment in a single chassis can be arranged in multiple nodes, and the nodes can be dedicated to certain functions or include certain types of equipment. Each node contains a shell and is usually called a "node sliding part". For example, there may be a plurality of computing node sliding parts and a plurality of storage node sliding parts. The computing node sliding components may include a baseboard management controller (BMC), a platform controller hub (PCH), a power supply, and one or more central processing units (CPU). Regardless of function, each node sliding component must be assembled to the chassis and provide an internal path for transferring heat from the electronic components. The case usually includes a fan, which draws air from the sliding parts of the node to transfer heat through convection.

In the conventional system, the node sliding parts are attached to the chassis via fasteners, such as screws. One benefit of these conventional fastening systems is that they provide a firm connection between the chassis and the sliding parts of the node. However, these conventional fastening systems require extra time to remove the node sliding components from the chassis. They also require the operator to carry tools to perform removal and attachment.

In order to overcome these problems, a toolless fastening system has been developed. The toolless fastening system relies on a handle to attach the node sliding part to the chassis. FIG. 1A shows a single node sliding part 10 of the prior art. The single node sliding part 10 includes a front input/output (I/O) bracket 12. As shown in the figure, the handle 14 is in the locked position. In the locked position, the engagement arm (not shown) of the handle 14 overlaps with the opening in the chassis on one side of the single node sliding part 10. In order to release the single node sliding part 10 from the chassis, the button 16 is pressed, and the handle 14 can be unscrewed from the front input-output bracket 12. Then, the single node sliding part 10 can be removed from the chassis. Similarly, FIG. 1B shows a two-node sliding component 20 in the prior art. The two-node sliding component 20 includes a front input/output (I/O) bracket 22 and a handle 24. The height of the double-node sliding component 20 is twice that of the single-node sliding component 10. In order to release the dual-node sliding member 20 from the chassis, the button 26 is pressed and the handle 24 can be unscrewed from the front input/output bracket 22 to disengage the handle 24 from the chassis.

The button-released lever system in the node sliding part of the prior art has some problems. First of all, because the electronic parts contained in the node sliding parts generate heat, it is desired to maximize the airflow into the front input and output bracket to enhance the heat transfer from the electronic parts. The button release handle system in the node sliding part of the prior art utilizes the critical space on the front input and output bracket, resulting in less airflow. Secondly, the button release handle system also suffers from connection and strength issues. The button may be unintentionally engaged to release the handle. Vibration and impact on the sliding parts of the node may cause the button to be released accidentally, or damage the front input and output bracket or the sliding parts of the node.

The present disclosure aims at the improvement of the handle mechanism. Among other benefits, it provides a node sliding part that is easy to install and remove, allows an increase in air flow into the node sliding part, and reduces the risk of damage or separation of the node sliding part during impact and vibration.

Figure 2 shows a dual-node sliding component 30 with a housing, which contains various electronic modules and components. The top cover of the housing of the dual-node sliding component 30 has been removed in Figure 2 to expose the internal electronic components. The housing of the dual-node sliding component 30 includes a removable front bracket 32 that includes various input and output ports, such as a universal serial bus (USB) port, a mini universal serial bus port, a plug for a card, and the like. The handle 40 is located on or adjacent to the front support 32. The handle 40 is used to connect the dual-node sliding component 30 to the electronic chassis, which will be described in more detail in FIGS. 8A to 8C.

Figure 3 shows an exploded view of the handle 40 in Figure 2. The handle 40 includes a fitting portion 42 that allows the handle 40 to be pivotally fitted to the dual node sliding part 30. As shown in the figure, the assembling part 42 includes a hole 43 for receiving a pin structure in the dual-node sliding member 30, as shown in FIG. 5. The handle 40 rotates around the pin structure. Other assembly techniques can also be used.

The handle 40 includes an engaging arm 44 for engaging the electronic case. In the embodiment shown, the engagement arm 44 is near the assembly portion 42 but may be located far away from the assembly portion 42 in other embodiments. The actuating arm 46 of the handle 40 is located on the opposite side of the fitting part 42 opposite to the engaging arm 44. Adjacent to the terminal end of the handle 40, the actuating arm 46 includes a bore 48 and a slot 49 for connecting to the latch 50.

The latch 50 slides in the slot 49, whereby the release portion 52 of the latch 50 is on one side of the handle 40 and the hook portion 54 is on the other side of the handle 40 facing the dual node sliding member 30. The latch 50 is maintained on the handle 40 by a pin or screw 58 which extends through the through hole 48 on the handle 40 and the assembly hole 56 in the central area of the latch 50. The latch 50 can pivot about the screw 58, but is deflected to the closed position by the spring mechanism 60, which is held in the groove 49 in a compressed state. Therefore, when the release portion 52 is manually actuated by the user, the user's action resists the force of the spring mechanism 60.

Figures 4A and 4B are perspective views of the two-node sliding member 30 with the front bracket 32, showing more details. Figure 4A shows the actuating arm 46 of the handle 40 in the first position (Figure 3). In the first position, the engagement arm 44 of the handle 40 (Figure 3) locks the dual-node sliding member 30 to the electronic chassis . Figure 4B shows the actuating arm 46 of the handle 40 in the second position (Figure 3). In the second position, the engaging arm 44 of the handle 40 (Figure 3) is released from the electronic chassis. As shown in Figure 4A, the user applies force to the release portion 52 of the latch 50, causing the hook portion 54 (not shown in Figure 4A) of the latch 50 to be released from the snap mechanism 65 on the front bracket 32 . As shown in FIG. 4B, once the hook portion 54 of the latch 50 is released from the buckle mechanism 65, the handle 40 is unscrewed from the front bracket 32. In this way, the dual-node sliding member 30 does not require any tools to release it from the electronic chassis.

Figure 4A also assists in showing an advantage of the thermal control of the handle 40. In the illustrated embodiment, the dual-node sliding component 30 includes a baseboard management controller (BMC) 66, and the baseboard management controller 66 may include a carrier board (for example, an M.2/M.3 carrier board). The baseboard management controller 66 is an example of an electronic component usually included in the two-node sliding component 30, and substantially generates an amount of heat. Because of the low profile of the handle 40 and there is actually no need to use the larger button mechanism for releasing the handle 40 that exists in the system of the prior art, the larger exposed area is used to allow the air holes on the front bracket 32 to escape from the double node. The outside of the sliding member 30 receives an air flow 70 (as shown by a straight arrow). As the velocity of the airflow 70 entering the air hole on the handle 40 increases, the convection of the airflow 70 (indicated by the curved arrow near the baseboard management controller 66) in the dual-node sliding member 30 comes from the baseboard management controller 66 (and other components) ) The heat transfer is enhanced. For example, due to the design of the handle 40 compared to the conventional handle system, the airflow rate in this area is increased by 15%. Therefore, the power of the baseboard management controller 66 and other cards can be increased. It should be understood that due to other required components, such as various input and output ports, the entire front bracket 32 may not include air holes. The front bracket 32 may also require other bus bars and interconnect components, such as a peripheral component interconnect express (PCIe) slot 72 for receiving cards and drives. Accordingly, by minimizing the area of the front bracket 32 required by the handle 40, more area can also be used for other input and output components.

Fig. 5 shows the inside of the double-node sliding member 30 in the corner area circled in Fig. 4B. The assembly bracket assembly 80 for the handle 40 is attached to the three inner surfaces of the front bracket 32. The assembly bracket assembly 80 includes a pin 82 that fits through the hole 43 in the assembly portion 42 of the handle 40 (Figure 3). The assembly bracket assembly 80 includes a plurality of fasteners 84 to be retained on the front bracket 32. The fastener 84 may include rivets, screws, and/or threaded caps for receiving screws. As shown in Figure 5, the fastener 84 includes five rivets and two screw caps. The screw cap receives screws from the outside of the dual-node sliding part 30, and the screws maintain the entire front bracket 32 on the dual-node sliding part 30. Therefore, when those screws are removed, the front bracket 32 can be removed from the dual node sliding part 30, but the assembly bracket assembly 80 and the handle 40 are still attached to the front bracket 32 by five rivets.

In order to bias the actuating arm 46 of the handle 40 to the open position (FIG. 4B ), the spring mechanism 86 of the assembly bracket assembly 80 acts on the assembly portion 42 of the handle 40. The terminating element 88 limits the rotational movement of the handle 40 about the pin 82. When the handle 40 is moved to the open position, the engaging arm 44 is screwed into the housing of the dual-node sliding component 30, and the terminating element 88 contacts the engaging arm 44. The terminating element 88 limits the total rotation angle of the handle 40 between the first locking position (Figure 4A) and the second release position (Figure 4B) to approximately 80 degrees.

As the front bracket 32 is attached on three different sides, the assembly bracket assembly 80 provides enhanced structural support for the handle 40. As such, there is less risk of accidental detachment of the handle 40 or deformation of the handle 40 or the front bracket 32 due to impact and/or vibration. In addition, the opposite end of the handle 40 is attached to the front bracket 32 by the latch 50 to provide additional structural integrity for the handle 40. Therefore, the assembly of the assembly bracket assembly 80 is to fix the handle 40 at one end and the latch 50 to the other end of the handle 40 to provide more reliability for the node sliding parts during transportation and operation. Compared with the conventional handle system that experienced problems during the 20G impact test, the handle 40 can withstand the 20G impact test on the sliding parts of the node.

FIGS. 6 and 7 respectively show the front view of the dual-node sliding member 30 and the front view of the single-node sliding member 90 described previously. The handle 40 is modular because the same handle 40 can be used on different types of dual-node sliding parts 30 and different types of single-node sliding parts 90. Different node sliding parts 30 and 90 can provide different functions (for example, motherboard sliding parts, hard disk drive (HDD) sliding parts, virtual hard disk drive sliding parts, etc.). As shown in FIG. 6, the handle 40 has a low profile, and the low profile extends along the bottom edge of the front bracket 32. Similarly, in FIG. 7, the handle 40 has a low profile, and the low profile extends along the bottom edge of the front bracket 92 of the single node sliding member 90. The engagement arm 44 of the handle 40 extends outward from the housings of both the dual-node sliding component 30 and the single-node sliding component 90 by the same distance.

From a geometric point of view, the dual-node sliding member 30 in FIG. 6 and the single-node sliding member 90 in FIG. 7 have the same width, but the dual-node sliding member 30 has twice the height of the single-node sliding member 90. In one embodiment, the width of the dual-node sliding member 30 and the single-node sliding member 90 are both approximately 212 mm, the height of the dual-node sliding member 30 is approximately 80 mm, and the height of the single-node sliding member 90 is approximately 40 mm.

8A, 8B, and 8C show an electronic chassis 100 that can accommodate a dual-node sliding component 30 or a single-node sliding component 90 (shown in FIG. 7). As shown in Figure 8A, the electronic case 100 includes a central wall 102 extending along its length. Two dual-node sliding parts 30 are located side by side on both sides of the central wall 102 in the electronic case 100. Each dual-node sliding component 30 slides into the shell of the electronic chassis 100. Each dual-node sliding component 30 includes a connector on the back opposite to the front bracket 32, and the electrical connector of the electronic chassis 100 overlaps with the mechanical connector. When the dual-node sliding member 30 is placed in the final installation position in the electronic chassis 100, the handle 40 for each dual-node sliding member 30 then locks the dual-node sliding member 30 to the central wall 102 or outer wall of the electronic chassis 100 106. During operation, the fan 104 in the electronic chassis 100 introduces air into the front bracket 32 of the dual-node sliding member 30, as shown in Figure 4A.

Fig. 8B is an internal view of the corner of the electronic case 100 of Fig. 8A, and the double-node sliding component 30 is not installed. The outer wall 106 includes a lower opening 108a and an upper opening 108b that can receive the engaging arm 44 of the handle 40 (both shown in FIG. 3). FIG. 8C is an external view of the corner of the electronic case 100, and the engagement arm 44 of the handle 40 is shown in the locked position in the lower opening 108a. When the electronic case 100 accommodates the dual-node sliding component 30 (in FIG. 8A), only the lower opening 108a is used to lock the engaging arm 44 of the handle 40 of the dual-node sliding component 30. When the electronic chassis 100 accommodates a pair of stacked single-node sliding components 90 (FIG. 7 ), the lower opening 108 a is used to lock the engaging arm 44 of the handle 40 of the lower single-node sliding component 90. The upper opening 108b is used to lock the engaging arm 44 of the handle 40 of the upper single node sliding component 90. Although not shown in Figure 8A, the central wall 102 will also have a pair of openings corresponding to the node sliding part on the right hand side of the electronic chassis 100 in Figure 8A.
