Description

Technical Field

[0001] This invention relates to a handle module and a rack system, and more particularly to a handle module that facilitates the effortless mounting of electronic devices to a rack and a rack system incorporating the handle module. Background Technology

[0002] With the rapid development of cutting-edge technologies such as the Internet of Things (IoT), edge computing, and artificial intelligence, electronic devices with massive information processing capabilities, such as servers, play an indispensable role. Generally, multiple electronic devices can be installed in racks to improve space utilization. However, there is a need to remove and reinstall electronic devices after they are installed in the rack. For example, when maintenance or repair is required, the electronic device needs to be removed from the rack, and then reinstalled after the maintenance or repair is completed. If the installation and removal methods for electronic devices from racks are not ideal, it may affect work efficiency and safety. Therefore, improving the installation and / or removal methods for electronic devices from racks is an ongoing goal for relevant industry players. Summary of the Invention

[0003] According to one embodiment of the present invention, a handle module is provided for mounting on a housing of an electronic device. The handle module includes a handle and a force-saving component. The handle is rotatably mounted on the housing. The force-saving component includes a first force-saving element and a second force-saving element. The first force-saving element is mounted on the handle, and the second force-saving element is mounted on the housing corresponding to the first force-saving element. An attraction force exists between the first and second force-saving elements, and this attraction force increases as the handle moves from an open position to a closed position.

[0004] According to another embodiment of the present invention, a rack system is provided, comprising a rack, an electronic device, and a handle module. The electronic device includes a housing. The handle module is disposed in the housing. The handle module includes a handle and a force-saving component. The handle is rotatably disposed in the housing. The force-saving component includes a first force-saving element and a second force-saving element. The first force-saving element is disposed in the handle, and the second force-saving element is disposed in the housing corresponding to the first force-saving element. An attraction force exists between the first and second force-saving elements. The attraction force increases as the handle moves from an open position to a closed position, and when the handle is in the closed position, the electronic device is mounted on the rack.

[0005] Compared to existing technologies, this invention incorporates a force-saving component in the handle module. The attraction between the first and second force-saving components allows the handle module to reduce the force required to mount electronic devices onto the rack when used for mounting electronic devices. Furthermore, it prevents the handle from popping out at high speed when the electronic devices are removed from the rack, thus improving safety. Attached Figure Description

[0066] This invention uses terms such as "first," "second," etc., to describe elements, regions, layers, and / or sections. However, it should be understood that these terms are only used to distinguish one element, region, layer, and / or section from another, and do not inherently imply or represent any prior ordinal number of the element, nor do they represent the arrangement order of one element with another, or the order of manufacturing methods. Therefore, without departing from the scope of the specific embodiments of this invention, the first element, region, layer, and / or section discussed below may also be referred to as the second element, region, layer, and / or section. The terms used in the claims may not be the same as those in the description, and may be replaced by first, second, third… according to the order of the elements declared in the claims.

[0067] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the rack system 10 according to an embodiment of the present invention. Figure 2 yes Figure 1 A top view of the rack system 10 in the middle. Figure 1 and Figure 2 In the middle, electronic device 200 has not yet been installed on rack 300. Figure 3 yes Figure 2 An enlarged view of section A. (See image below.) Figure 1 As shown, the rack system 10 includes a rack 300, an electronic device 200, and a handle module 100. The electronic device 200 includes a housing 210, and the handle module 100 is disposed on the housing 210 of the electronic device 200. The user can install the electronic device 200 onto the rack 300 with the assistance of the handle module 100. Figure 1 In this example, an electronic device 200 is installed within a rack 300, but the invention is not limited thereto. In some embodiments, multiple electronic devices 200 may be installed within the rack 300, and the multiple electronic devices 200 may be arranged along a vertical direction (in this case, direction Z). To clearly show the portion of the handle module 100 obscured by the housing 210, Figure 2 Lieutenant General Figure 1 The shell portion 211 is omitted, and the boundary of the shell portion 211 is marked with a dashed line DL1.

[0068] like Figure 2 As shown, the electronic device 200 may also include a local unit 220 and a heat dissipation device 230 disposed within the housing 210. Figure 2 The boundary of the unit 220 and the heat dissipation device 230 is marked by a dashed line DL2. For example... Figure 2As shown, the unit 220 is disposed within the housing 210 on the side near the handle module 100 (here, the front side), and the heat dissipation device 230 is disposed within the housing 210 on the side away from the handle module 100 (here, the rear side). The heat dissipation device 230 is used to cool the unit 220. The unit 220 may be, for example, a server, but is not limited thereto. The heat dissipation device 230 may be, for example, a liquid cooling device, a fan, or heat sink fins, but is not limited thereto. In this embodiment, the heat dissipation device 230 is described as a liquid cooling device. The heat dissipation device 230 includes a first liquid cooling connector 231, and the rack 300 includes a second liquid cooling connector 310 corresponding to the first liquid cooling connector 231. The first liquid cooling connector 231 is used to mate with the second liquid cooling connector 310 for exchanging cooling liquid. During the guiding stroke of the first liquid cooling connector 231 and the second liquid cooling connector 310 mate, resistance is generated between the first liquid cooling connector 231 and the second liquid cooling connector 310, and the resistance pushes the unit 220 outward from the rack 300.

[0069] Please refer to Figure 9 This is a schematic diagram of the connection between the first liquid cooling connector 231 and the second liquid cooling connector 310 according to an embodiment of the present invention. For the sake of simplicity, Figure 9 Only the first liquid cooling connector 231, the second liquid cooling connector 310, and part of the frame 300 are shown in the drawing; other components are omitted. Figure 9 As shown, the first liquid cooling connector 231 may include a shaft tube portion AP, and the second liquid cooling connector 310 may include a sleeve portion SP. When the first liquid cooling connector 231 is moved so that the end T1 of its shaft tube portion AP aligns with the end T2 of its sleeve portion SP, as... Figure 9 As shown in Part A, the first liquid cooling connector 231 and the second liquid cooling connector 310 begin to mate. As the first liquid cooling connector 231 continues to move, its shaft tube portion AP is inserted into the sleeve portion SP and positioned within the sleeve portion SP, as... Figure 9 As shown in Part B, the first liquid cooling connector 231 and the second liquid cooling connector 310 are docked. The aforementioned "guide stroke" refers to the distance QC that the shaft tube AP moves from the start of docking to the completion of docking. According to one embodiment of the present invention, the guide stroke (i.e., the distance QC) for the docking of the first liquid cooling connector 231 and the second liquid cooling connector 310 can be 40 millimeters (mm).

[0070] Please refer to the following: Figure 2The handle module 100 includes a handle 110 and a force-saving component (not otherwise labeled). The force-saving component includes a first force-saving element 131 and a second force-saving element 132. The first force-saving element 131 is disposed on the handle 110, and the second force-saving element 132 is disposed on the housing 210 corresponding to the first force-saving element 131. There are attraction forces AF1 and AF2 between the first force-saving element 131 and the second force-saving element 132, where attraction force AF1 is the force acting on the first force-saving element 131, and attraction force AF2 is the force acting on the second force-saving element 132. When the handle 110 is in the open position (e.g., ...), Figure 2 Move the indicated position to the closed position (e.g., the position shown). Figure 7 , Figure 8 During the process (as shown in the figure), the attractive forces AF1 and AF2 will increase. Therefore, the attractive forces AF1 and AF2 between the first force-saving component 131 and the second force-saving component 132 can act as an aid in mounting the electronic device 200 onto the rack 300, thereby reducing the resistance encountered by the electronic device 200 in mounting onto the rack 300, such as friction or the resistance generated between the aforementioned first liquid cooling connector 231 and the second liquid cooling connector 310, thus facilitating the effortless mounting of the electronic device 200 onto the rack 300.

[0071] In detail, Figure 2 In the middle, handle 110 is in the open position. At this time, the first liquid cooling connector 231 and the second liquid cooling connector 310 have not yet begun to connect or are about to begin connecting (see...). Figure 9 (Part A of the invention). An included angle A1 exists between the handle 110 and the housing 210, and the included angle A1 may be less than or equal to 90 degrees. According to one embodiment of the invention, when the handle 110 is in the open position, the included angle A1 may be 60 to 80 degrees, for example, 70 degrees. Figure 3 As shown, when the handle 110 is in the open position, the abutment portion 320 of the frame 300 and the abutment top 112 of the handle 110 do not abut against each other.

[0072] The first force-saving component 131 is fixed to the surface of the handle 110 facing the housing 210 (unless otherwise labeled), and the second force-saving component 132 is rotatably disposed on the housing 210, wherein the second force-saving component 132 is rotatably disposed on the housing portion 211 (see See Figure 1 The inner surface of the handle module 100. Specifically, the handle module 100 may further include a carrier 133 and a fixed shaft 134. A second force-saving component 132 is fixedly connected to the carrier 133, which may be made of, for example, metal or plastic, thus facilitating processing or molding. The fixed shaft 134 connects the carrier 133 to the housing 210, and also serves as a pivot for the rotation of the carrier 133 relative to the housing 210. The second force-saving component 132 can rotate relative to the housing 210 via the carrier 133 and the fixed shaft 134.

[0073] The handle module 100 may further include another carrier (not shown) and a locking fastener 136. A first effort-saving component 131 is fixedly connected to the other carrier, which can be embedded in the receiving space (not shown) of the handle 110. The locking fastener 136 is used to fix the other carrier to the handle 110. However, the present invention is not limited thereto. In some embodiments, the first effort-saving component 131 can be directly embedded in the receiving space of the handle 110 and partially protrude from or not protrude from the surface of the handle 110 facing the housing 210, or it can be fixed to the handle 110 by adhesive.

[0074] The first force-saving element 131 and the second force-saving element 132 can be magnetic elements, such as magnets or coils. In this case, the attractive forces AF1 and AF2 are magnetic forces, and the magnetic poles of the first force-saving element 131 facing the second force-saving element 132 are different from the magnetic poles of the second force-saving element 132 facing the first force-saving element 131, allowing the first force-saving element 131 and the second force-saving element 132 to attract each other. Since the second force-saving element 132 is rotatably mounted on the housing 210, when the handle 110 rotates relative to the housing 210, it causes the first force-saving element 131 to rotate relative to the housing 210 as well. This facilitates the rotation of the second force-saving element 132 under the influence of the first force-saving element 131, thereby helping to maintain the strength of the attractive forces AF1 and AF2 between the second force-saving element 132 and the first force-saving element 131. For more details, please refer to [reference needed]. Figure 6 Related explanations.

[0075] Please refer to the following at the same time Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 4 yes Figure 2 An external schematic diagram of the center handle module 100. Figure 5 yes Figure 4 An exploded view of the handle module 100. The handle module 100 also includes a plate 120, which is fixed to the housing 210, wherein the handle 110 is pivotally mounted on the plate 120.

[0076] In this embodiment, the plate 120 includes a first slide rail 123 and a second slide rail 124, and the handle 110 includes a first guide post 114 and a second guide post 115. The first guide post 114 and the second guide post 115 are pivotally disposed in the first slide rail 123 and the second slide rail 124, respectively. The first guide post 114 can serve as the active shaft for driving the plate 120 to move, and the second guide post 115 can serve as the guide shaft for guiding the rotation of the handle 110. Thus, the handle module 100 is a dual-axis handle module, but it is not limited to this. In other embodiments, the handle module 100 can also be configured as a single-axis handle module. In this embodiment, the first guide post 114 and the second guide post 115 are cylinders and are integrally formed on the handle 110, but it is not limited to this. In some embodiments, the first guide post 114 and the second guide post 115 can be screws, studs, or steel posts, and can be fixed to the handle 110 by locking.

[0077] The same handle module 100 contains two plates 120, respectively disposed above and below the handle 110. Each plate 120 corresponding to the handle 110 includes two first guide posts 114 respectively disposed on the upper and lower surfaces of the handle 110, and each plate 120 corresponding to the handle 110 includes two second guide posts 115 respectively disposed on the upper and lower surfaces of the handle 110. However, the present invention is not limited thereto; in other embodiments, the number of plates 120, first guide posts 114, and second guide posts 115 can be adjusted according to actual needs. Figure 2 , Figure 3 When the handle 110 is in the open position, the first guide post 114 is in the first position of the first slide rail 123, and the second guide post 115 is in the first position of the second slide rail 124.

[0078] The handle 110 may include a first positioning part 113 (see Figure 5In this embodiment, the first positioning portion 113 is exemplified as a recess formed on the surface of the handle 110. The plate 120 may include a second positioning portion 121 and a hole 122. The second positioning portion 121 is disposed in the hole 122, and a protrusion 121a is formed on the surface of the second positioning portion 121 facing the handle 110. When the handle 110 is in the open position, the protrusion 121a of the second positioning portion 121 can be correspondingly inserted into the first positioning portion 113, thereby engaging the first positioning portion 113 and the second positioning portion 121 with each other. In other words, in this embodiment, the first positioning portion 113 has a concave structure and the second positioning portion 121 has a convex structure, and they engage with each other through a concave-convex fit. In other embodiments, the structures of the first positioning portion 113 and the second positioning portion 121 can be interchanged, that is, the first positioning portion 113 has a convex structure and the second positioning portion 121 has a concave structure. Furthermore, in this embodiment, the second positioning part 121 is an independent component that can be separated from the plate 120, but it is not limited to this. In some embodiments, the second positioning part 121 can be integrally formed on the surface of the handle 110. Through the engaging relationship between the first positioning part 113 and the second positioning part 121, free wobbling when the handle 110 is in the open position can be prevented, thereby improving safety in use.

[0079] Please refer to Figure 7 and Figure 8 , Figure 7 yes Figure 1 Another top view of the rack system 10, in which electronic devices 200 are installed on rack 300. Figure 8 yes Figure 7 Enlarged view of section B. Figure 7 When handle 110 is in the closed position, the first liquid cooling connector 231 and the second liquid cooling connector 310 have completed their docking stroke (see...). Figure 9 Part B). Figure 8 As shown, when the handle 110 is in the closed position, one end of the handle 110 is snapped into the housing 210, and the other end of the handle 110 abuts against the frame 300. Here, the top 112 of the handle 110 abuts against the receiving part 320 of the frame 300, and the first force-saving member 131 and the second force-saving member 132 are in contact with each other.

[0080] In detail, the first force-saving component 131 and the second force-saving component 132 have attractive forces AF1 and AF2. When the handle 110 is in the closed position, the first force-saving component 131 and the second force-saving component 132 are attracted to each other and come into contact under the action of attractive forces AF1 and AF2.

[0081] The electronic device 200 may further include a latching member 240, which includes a latching part 241, a release button 242, and a mounting base 243. The mounting base 243 is fixed to the housing 210. The latching part 241 is retractably disposed on the mounting base 243, specifically retractably disposed laterally (i.e., parallel to direction X). The latching part 241 includes a guide surface 241a and a stop surface 241b. The release button 242 can drive the latching part 241 to extend or retract. When the release button 242 is pressed, the latching part 241 retracts into the mounting base 243. When the release button 242 is released, the latching part 241 extends out of the mounting base 243. Figure 8 The state shown is as described. How the release button 242 drives the extension and retraction of the latching part 241 is well known to those skilled in the art and will not be described in detail here.

[0082] The handle 110 may further include a latch 111 disposed at one end of the handle 110. The latch 111 includes a pushing surface 111a and a resisting surface 111b. When the handle 110 is about to enter the closed position, the pushing surface 111a of the latch 111 contacts the guide surface 241a of the latching part 241, causing the latching part 241 to retract into the fixing seat 243. After the pushing surface 111a leaves the guide surface 241a, the latching part 241 extends out of the fixing seat 243, and the stop surface 241b of the latching part 241 abuts against the resisting surface 111b of the latch 111, thereby restricting the movement of the latch 111 away from the housing 210 and preventing the handle 110 from popping out. In other words, when the handle 110 is in the closed position, the handle 110 can be latched onto the housing 210 by the latching member 240. To release the latch of the handle 110, press the release button 242 to drive the latch part 241 to retract into the fixing seat 243. In the absence of a stop surface 241b, the latch part 111 can move freely away from the housing 210.

[0083] In other embodiments, the electronic device 200 may omit the latch 240. Since there is an attraction AF1 and AF2 between the first force-saving element 131 and the second force-saving element 132, when the handle 110 is in the closed position, the attraction between the first force-saving element 131 and the second force-saving element 132 can also prevent the handle 110 from popping out.

[0084] Please refer to Figure 6 , it is Figure 1 Another top view of the rack system 10, in which the electronic device 200 has not yet been installed on the rack 300. Figure 6 In the middle, handle 110 is in the open position (see...) Figure 2 ) and closing position (see Figure 7The handle 110 may be in the intermediate position between the open and closed positions. For example, the handle 110 may be in the process of moving from the open position to the closed position, or the handle 110 may be in the process of moving from the closed position to the open position. At this time, the first guide post 114 may be located in the first position of the first slide rail 123 (see...). Figure 3 ) and the second position (see Figure 8 The second guide post 115 is located between or in the second position of the second slide rail 124 (see...). Figure 3 ) and the second position (see Figure 8 )between.

[0085] In detail, when Figure 6 During the process of moving the handle 110 from the open position to the closed position, the first liquid cooling connector 231 and the second liquid cooling connector 310 are docking. The resistance between the first liquid cooling connector 231 and the second liquid cooling connector 310 will push the electronic device 200 outward (that is, push the electronic device 200 outward along the Y direction). The second force-saving element 132 provided on the housing 210 can provide an inward attraction force AF1 provided on the first force-saving element 131 provided on the handle 110 (see Figure 2 This helps to counteract resistance and allows the electronic device 200 to be mounted on the rack 300 in a less strenuous manner.

[0086] Furthermore, the first force-saving component 131 has a first surface 131a, and the second force-saving component 132 has a second surface 132a facing the first surface 131a. Compared to the case where the second surface 132a is not directly facing the first surface 131a, when the second surface 132a is directly facing the first surface 131a, the attractive forces AF1 and AF2 between the second force-saving component 132 and the first force-saving component 131 (see...) Figure 2 The aforementioned "second surface 132a is directly opposite the first surface 131a" may refer to the second surface 132a being parallel to the first surface 131a, and the second surface 132a and the first surface 131a partially or completely overlapping in a direction perpendicular to the first surface 131a or the second surface 132a.

[0087] It should be noted that when the handle 110 rotates relative to the housing 210, the orientation of the first surface 131a continuously changes. The second force-saving element 132, rotatably mounted on the housing 210, facilitates its rotation under the influence of the first force-saving element 131. This, in turn, helps maintain the second surface 132a facing the first surface 131a, i.e., helps keep the first surface 131a and the second surface 132a parallel. This, in turn, helps maintain the attraction forces AF1 and AF2 between the second force-saving element 132 and the first force-saving element 131 (see...). Figure 2The strength of the magnetic poles can be adjusted. For example, when the first force-saving element 131 and the second force-saving element 132 are magnetic elements, the magnetic pole strength of the first force-saving element 131 and the second force-saving element 132 can be adjusted so that the included angle A1 between the handle 110 and the housing 210 is within a predetermined angle, and the first surface 131a and the second surface 132a can remain parallel. According to an embodiment of the present invention, the aforementioned predetermined angle can be, for example, 60 degrees to 0 degrees.

[0088] when Figure 6 During the process of the handle 110 moving from the closed position to the open position, the first liquid cooling connector 231 and the second liquid cooling connector 310 are disengaging. The resistance between the first liquid cooling connector 231 and the second liquid cooling connector 310 will push the electronic device 200 outward (that is, push the electronic device 200 outward along the Y direction), and the handle 110 will also be driven to pop outward. If the handle 110 pops out too quickly, it may hit the equipment and personnel around the rack system 10, thus affecting the safety of use.

[0089] To address the issue of excessively fast ejection speed of the handle 110, existing handle modules are equipped with a spring. One end of the spring is fixed to the plate 120, and the other end is fixed to the handle 110. The spring provides a force that pulls the handle 110 towards the housing 210, thereby slowing down the ejection speed. However, as the handle 110 approaches the open position, the spring's deformation increases, and the elastic force also increases accordingly. Excessive elastic force may cause the engagement between the first positioning part 113 and the second positioning part 121 to loosen, causing the handle 110 to wobble freely when in the open position. This invention provides an inward attraction AF1 from the first positioning part 131 via the second force-saving part 132, which slows down the ejection speed of the handle 110, improves safety, and is less likely to affect the engagement between the first positioning part 113 and the second positioning part 121.

[0090] As can be seen from the above, when the electronic device 200 is not yet installed on the rack 300, the handle 110 is in the open position (e.g., Figure 2 As shown, when installing the electronic device 200 onto the rack 300, the user can first grasp the handle 110 and push it to move the electronic device 200 into the rack 300, causing the first liquid cooling connector 231 to align with the second liquid cooling connector 310. Through a labor-saving component, the handle module 100 guides the electronic device 200 to align with the first liquid cooling connector 231 and the second liquid cooling connector 310, significantly improving the labor-saving effect. Once the first liquid cooling connector 231 and the second liquid cooling connector 310 are aligned, the electronic device 200 is installed on the rack 300. In other words, when the electronic device 200 is installed on the rack 300, the first liquid cooling connector 231 and the second liquid cooling connector 310 are fixedly connected; this fixed connection means that there is no relative movement between the first liquid cooling connector 231 and the second liquid cooling connector 310.

[0091] When maintenance or repair requires disengaging the electronic device 200 from the rack 300, the user can press the release button 242 to release the handle 110 from the housing 210. Then, the user can grasp the handle 110 and pull it to move the electronic device 200 out of the rack 300. In other words, when the handle 110 leaves the closed position, the electronic device 200 is released from the rack 300. The force-saving component prevents the handle 110 from popping out rapidly once it is no longer locked to the housing 210.

[0092] In this embodiment, there are two handle modules 100. During operation, the user can hold both handles 110 with both hands to install or remove the electronic device 200 from the frame 300. However, the invention is not limited to this. In some embodiments, there may be only one handle module 100. During operation, the user can hold the handle 110 with one hand and the electronic device 200 on the opposite side of the handle 110 with the other hand. A single handle module 100 can also achieve the effects of saving effort and slowing down the pop-out speed of the handle 110. In this embodiment, the heat dissipation device 230 is a liquid cooling device as an example, but it is not limited to this. When the heat dissipation device 230 is not a liquid cooling device, the handle module 100 can also achieve the effects of saving effort and slowing down the pop-out speed of the handle 110. In this embodiment, the number of the first force-saving component 131 and the second force-saving component 132 in the same handle module 100 is one, but it is not limited to this. The number of the first force-saving component 131 and the second force-saving component 132 can be adjusted according to actual needs. When the same handle module 100 includes multiple first force-saving components 131 and multiple second force-saving components 132, the number of first force-saving components 131 and the number of second force-saving components 132 can be the same. Multiple first force-saving components 131 can be spaced apart on the handle 110, and multiple second force-saving components 132 can be spaced apart on the housing 210 corresponding to multiple first force-saving components 131.

[0093] Please refer to Figure 10 This diagram illustrates the relationship between the distance between the first and second liquid-cooling connectors and the applied force according to an embodiment and a comparative example of the present invention. Specifically, electronic devices are mounted on a frame using a handle module according to an embodiment and a handle module from a comparative example, respectively. During the guiding stroke of the first and second liquid-cooling connectors as they enter the docking position, the applied force of a worker's single hand is measured at different distances between the first and second liquid-cooling connectors. The difference between the handle module of the embodiment and the handle module of the comparative example is that the handle module of the comparative example does not include a force-saving component. Figure 10It is known that when the first liquid cooling connector and the second liquid cooling connector enter the guide stroke, the applied force gradually increases as the gap decreases. When the gap is close to 15mm, the applied force reaches its maximum value of about 70 Newtons (N). When using the handle module of the comparative example, the applied force only decreases slightly at the end of the guide stroke, for example, the stroke with a gap of 15mm to 0mm. However, using the handle module according to the present invention can significantly reduce the applied force required at the end of the guide stroke.

[0094] Compared to existing technologies, this invention incorporates a force-saving component in the handle module. The attraction between the first and second force-saving components allows the handle module to reduce the force required to mount electronic devices onto the rack when used for mounting electronic devices. Furthermore, it prevents the handle from popping out at high speed when the electronic devices are removed from the rack, thus improving safety.

[0095] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made in accordance with the claims of the present invention should be included within the scope of the present invention.
