Description

Technical Field

[0001] This application relates to the field of electronic devices, and more particularly to a connection component, a cabinet component, and a data center system. Background Technology

[0002] With the increase in mobile users and digital transformation, customers' demand for data processing is constantly growing. This increase in data processing needs necessitates an increase in the number of servers. Servers typically consist of racks and functional components housed within them. When more servers are added, multiple servers need to be combined into a single rack, i.e., connected together. However, in existing technologies, the connection devices used for combining racks result in a long merging time and significant errors in the spacing between multiple racks.

[0003] Therefore, a new type of component is urgently needed to solve the above problems. Utility Model Content

[0004] This application provides a connection component, a rack component, and a data center system, which can solve the above-mentioned problems.

[0005] In a first aspect, this application provides a connecting assembly. The connecting assembly includes a tube body, a stud, and an expansion member. The first end of the tube body has an expansion section with a slot extending axially along the tube body. The stud includes a column and a threaded head, the threaded head being located at the first end of the column, and at least a portion of the outer circumferential surface of the column having external threads. The expansion member has a through hole, at least a portion of the inner wall of the through hole having internal threads, and the outer circumferential surface of the expansion member having a protrusion. The column passes through the tube body, the threaded head protrudes at the second end of the tube body, the expansion member is located at the first end of the tube body, the internal thread is threaded onto the external thread, the protrusion and the slot slide in axial direction along the tube body, and the outer diameter of the expansion member is larger than the inner diameter of the expansion section.

[0006] In this embodiment, when the connecting assembly is used to connect the first and second cabinets, the tube can pass through the first and second cabinets. The expansion section on the tube can be located in the through hole of the first or second cabinet. The stud passes through the tube, with the screw head located at the first end of the stud and the second end of the stud having an external thread. The expansion member is screwed to the second end of the stud, driving the screw head to rotate. The expansion member will move towards the screw head along the axial direction of the tube. Since the outer diameter of the expansion member is larger than the inner diameter of the expansion section, the expansion member can cause the expansion section to expand radially during the movement, so that the outer circumferential surface of the expansion section abuts against the inner wall of the first through hole. The expansion member will then be unable to continue moving towards the screw head along the axial direction of the tube. At this time, the connecting assembly connects the first and second cabinets, and the expansion member abuts against the inner wall of the first through hole, so that the through holes of the first and second cabinets are coaxially arranged along the axial direction of the tube, ensuring that the first and second cabinets are flush. Continuing to drive the screw head to rotate will cause the expansion component to move the second and first cabinets to one side of each other, thus aligning the first and second cabinets together. In this method, when connecting the first and second cabinets, one worker simply passes the connecting component through the first through hole on the first cabinet and the through hole on the second cabinet, and then drives the screw head to rotate to achieve the connection and alignment of the first and second cabinets. This simplifies the operation process of connecting and aligning the first and second cabinets and improves the efficiency of connecting and aligning multiple cabinets.

[0007] In one embodiment, there are multiple slits and protrusions, and the multiple slits and multiple protrusions are arranged in a one-to-one correspondence. This ensures that the expansion member can move along the axial direction of the tube body.

[0008] In one embodiment, multiple slits are evenly distributed around the axis of the tube in the expansion section, and multiple protrusions are evenly distributed on the outer peripheral surface of the expansion member. The multiple slits are evenly arranged in the expansion section, which can divide the expansion section into multiple expansion petals of the same size. Each expansion petal is subjected to the same expansion force from the expansion member, so that the outer peripheral surface of the expansion section can relatively evenly abut against the inner wall of the through hole in the cabinet.

[0009] In one embodiment, the outer diameter of the expansion member gradually decreases from the first end to the second end of the tube. This allows the expansion section to gradually expand as the expansion member moves towards the end where the screw head is located.

[0010] In one embodiment, the inner diameter of the expansion section gradually decreases from the first end to the second end of the tube. This makes it easier for the expansion component to mate with the expansion section.

[0011] In one embodiment, the connecting assembly further includes a positioning plate, with the second end of the tube body connected to the positioning plate, the positioning plate extending radially along the tube body. The connecting assembly also includes an anti-rotation component connected to the positioning plate, and the anti-rotation component and the expansion tube are located on the same side of the positioning plate. The positioning plate and the anti-rotation component ensure that no relative rotation occurs between the tube body and the studs when the connecting assembly connects the cabinet.

[0012] The number of anti-rotation components can be two, three, or four, and the anti-rotation components are set on both sides of the pipe body.

[0013] Secondly, this application provides a data cabinet assembly, which may include a first cabinet, a second cabinet, and a connecting component as described in any of the technical solutions in the first aspect; the first cabinet may include a first through hole, the second cabinet may include a second through hole, the first through hole and the second through hole are coaxially arranged, the connecting component may pass through the first through hole and the second through hole, and an expansion section is located inside the first through hole or the second through hole; wherein, the outer peripheral surface of the expansion section is used to abut against the inner wall of the first through hole or the second through hole.

[0014] In this embodiment, when the connecting assembly connects the first cabinet and the second cabinet, the tube in the connecting assembly passes through the first through hole and the second through hole. The expansion section in the tube can be located in the first through hole or the second through hole. The stud passes through the tube, and the expansion member cooperates with the stud. Driving the stud can move the expansion member along the axial direction of the tube, so that the expansion member drives the expansion section to expand radially. The expansion section can abut against the inner wall of the first through hole or the second through hole, so that the first cabinet and the second cabinet are also coaxially arranged along the axial direction of the tube, making the first cabinet and the second cabinet flush. Moreover, when the expansion section abuts against the inner wall of the first through hole or the second through hole, continuing to drive the stud can tighten the first cabinet and the second cabinet, so that the first cabinet and the second cabinet are connected side by side.

[0015] In one embodiment, the first cabinet includes a first frame and a first cover plate, with the first cover plate surrounding the first frame. The second cabinet includes a second frame and a second cover plate, with the second cover plate surrounding the second frame. Specifically, a first through-hole is provided in the first frame, and a second through-hole is provided in the second frame. More specifically, there can be multiple first through-holes evenly distributed on the first frame, and multiple second through-holes evenly distributed on the second frame, with each of the multiple first and multiple second through-holes corresponding to the other.

[0016] Thirdly, this application also provides a data center system, including electronic equipment and rack components as described in any of the technical solutions of the second aspect, wherein the electronic equipment is housed in a first rack and a second rack. The electronic equipment may be a battery module, server, router, disk drive, or monitor, etc. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0027] As the demand for data processing continues to increase, the number of servers used by users also needs to increase, which in turn requires an increase in the number of server racks to accommodate them. Multiple servers need to be grouped together to ensure sufficient spacing between them and to minimize vertical movement of the racks. In existing technologies, connectors are typically located at the top of the rack, which results in a larger space occupied by the rack along its height and a longer time required to connect adjacent racks.

[0028] Therefore, a new connection component is urgently needed to solve the above problems.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0034] The first frame 21b may include a first connecting frame 211, a second connecting frame 212, and a third connecting frame 213, with the third connecting frame 213 connecting the first connecting frame 211 and the second connecting frame 212. The first connecting frame 211 includes two first sub-connecting frames 211a and two first sub-connecting frames 211b. The two first sub-connecting frames 211a are arranged in parallel, and the two first sub-connecting frames 211b are also arranged in parallel. One of the first sub-connecting frames 211b connects the first ends of the two first sub-connecting frames 211a, and the other first sub-connecting frame 211b connects the second ends of the two first sub-connecting frames 211a.

The third sub-connecting frame 213a, the first sub-connecting frame 211a and the second connecting frame 212a are connected to each other to form the aforementioned side opening. The third sub-connecting frame 213a, the first connecting frame 211b and the second connecting frame 212b are connected to each other to form the aforementioned side opening.

[0035] The second cabinet 22 may include a second frame 22b and a second cover plate. The second cover plate is provided with openings on the top, bottom, and sides of the second frame 22b, forming a sealed accommodating space within the second frame 22b. The second cabinet 22 may also include a second partition 22a, which divides the accommodating space within the second frame 22b into multiple sub-spaces, each of which can accommodate the same or different electronic devices 30.

[0036] The second frame 22b may include a fourth connecting frame 221, a fifth connecting frame 222, and a sixth connecting frame 223. The sixth connecting frame 223 connects the fourth connecting frame 221 and the fifth connecting frame 222. The fourth connecting frame 221 includes two fourth sub-connecting frames 221a and two fourth sub-connecting frames 221b. The two fourth sub-connecting frames 221a are arranged in parallel, and the two fourth sub-connecting frames 221b are also arranged in parallel. One of the fourth sub-connecting frames 221b connects the first ends of the two fourth connecting frames 221a, and the other fourth connecting frame 221b connects the second ends of the two fourth connecting frames 221a. The two fourth sub-connecting frames 221a and the two fourth connecting frames 222b are connected to each other to form an opening on the top surface of the second frame 22b.

The two fifth sub-connecting frames 222a are arranged in parallel, and the two fifth sub-connecting frames 222b are also arranged in parallel. One fifth sub-connecting frame 222b connects the first ends of the two fifth sub-connecting frames 222a, and the other fifth sub-connecting frame 222b connects the second ends of the two fifth sub-connecting frames 222a. The two fifth sub-connecting frames 222a and the two fifth sub-connecting frames 222b are connected to each other to form the bottom opening of the second frame 22b. The sixth connecting frame 223 may include four sixth sub-connecting frames 223a.

[0037] The structures of the first cabinet 21 and the second cabinet 22 in the above embodiments can also be the same. Here, "the same" can refer to the fact that the structures of the first frame 21b and the second frame 22b are the same. When specifically setting up the first cabinet 21 and the second cabinet 22, the number and position of the first partition 21a in the first cabinet 21 and the second partition 22a in the second cabinet 22 can be different.

[0038] Figure 3 This is a partial cross-sectional view of the cabinet assembly provided in an embodiment of this application. Figure 4 This is a schematic diagram of a rack assembly provided in an embodiment of this application. (Refer to...) Figure 2 , Figure 3 and Figure 4The first cabinet 21 includes a first through hole 2130, and the second cabinet 22 includes a second through hole 2230. Specifically, the first through hole 2130 can be provided in the third sub-connecting frame 213a, and the first through hole 2130 penetrates the third sub-connecting frame 213a along the arrangement direction of the first cabinet 21 and the second cabinet 22. Furthermore, each third sub-frame 213a can have multiple first through holes 2130, which are spaced apart along the extension direction of the third sub-frame 213a, and the axial direction of the first through holes 2130 is perpendicular to the extension direction of the third sub-frame 213a. Correspondingly, the second through hole 2230 can be provided on the sixth sub-connecting frame 223a. Along the arrangement direction of the first cabinet 21 and the second cabinet 22, the second through hole 2230 penetrates the sixth sub-connecting frame 223a, and the number of second through holes 2230 on each sixth sub-frame 223a can be multiple, with the multiple second through holes 2230 spaced apart along the extension direction of the sixth sub-frame 223a. In the corresponding third sub-connecting frame 213a and sixth sub-connecting frame 223a, the multiple first through holes 2130 and the multiple second through holes 2230 are provided in a one-to-one correspondence. When merging the first cabinet 21 and the second cabinet 22, there can be multiple connecting components 40. Multiple connecting components 40 pass through the corresponding first through hole 2130 and second through hole 2230. The expansion section 410 of the connecting component 40 is located in the first through hole 2130 or the second through hole 2230. When the connecting component 40 connects the first cabinet 21 and the second cabinet 22, and the connecting component 40 passes from the first cabinet 21 to the second cabinet 22, the outer peripheral surface of the expansion section 410 in the connecting component 40 will abut against the inner wall of the second through hole 2230 under the action of the expansion member 42, so as to ensure that the second cabinet 22 will not move along the radial direction of the second through hole 2230. Moreover, when the outer peripheral surface of the expansion section 410 in the connecting component 40 abuts against the inner wall of the second through hole 2230, it will continue to drive the connecting component 40 to rotate, so as to tighten the first cabinet 21 and the second cabinet 22. Alternatively, the connecting component 40 can also extend from the second cabinet 22 toward the first cabinet 21. The outer peripheral surface of the expansion section 410 in the connecting component 40 will abut against the inner wall of the first through hole 2130 under the action of the expansion member 42. When the number of cabinets in the data center system or cabinet assembly needs to be increased, the cabinet assembly may also include a third cabinet, a fourth cabinet, and a fifth cabinet, etc. The structure of the third cabinet, the fourth cabinet, and the fifth cabinet is the same as the structure of the first cabinet 21. When the connecting component 40 connects the third cabinet to the first cabinet or the second cabinet, the connection method is the same as that of the first cabinet and the second cabinet.

[0039] The connection components will be described in more detail below.

[0040] Figure 5 This is a schematic diagram of a connection component provided in an embodiment of this application. Figure 6This is a cross-sectional view of a connection component provided in an embodiment of this application. Figure 4 The direction of X in the middle is from the first end to the second end of the tube 41, as shown in the reference. Figure 1 , Figure 3 , Figure 5 and Figure 6The connecting assembly 40 may include a tube body 41, a stud 43, and an expansion member 42. The first end of the tube body 41 has an expansion section 410 with a slot 411 extending axially along the tube body. The stud 43 includes a column body 430 and a screw head 431, the screw head 431 being fixed to the first end of the column body 430. At least a portion of the outer peripheral surface of the column body 430 has external threads. The expansion member 42 has a through hole 421, at least a portion of the inner wall of the through hole 421 having internal threads, and a protrusion 420 on the outer peripheral surface of the expansion member 42. The column 430 passes through the tube 41, the screw head 431 is exposed at the second end of the tube 41, the expansion member 42 is located at the first end of the tube 41, the second end of the column 430 can pass through the through hole 421 of the expansion member 42, the external thread on the column 430 is screwed into the internal thread in the through hole 421, the protrusion 420 and the gap 411 slide in the axial direction of the tube 41, and the outer diameter of the expansion member 42 is larger than the inner diameter of the expansion section 410. When the connecting assembly 40 is used to connect the first cabinet 21 and the second cabinet 22, the tube 41 passes through the first through hole 2130 on the first cabinet 21 and the second through hole 2230 on the second cabinet 22, and the expansion section 410 on the tube 41 is located in the first through hole 2130. The stud 43 is inserted into the tube 41, and the screw head 431 in the stud 43 can be located on one side of the first cabinet 21. The expansion member 42 is located on one side of the second cabinet 22, and the expansion member 42 is screwed to the second end of the stud 43's column 430, driving the screw head 431 to rotate. The expansion member 42 will move along the tube 41. As the expansion member 42 moves axially towards the screw head 431, its outer diameter is larger than the inner diameter of the expansion section 410. During this movement, the expansion member 42 can cause the expansion section 410 to expand radially until the outer circumferential surface of the expansion section 410 abuts against the inner wall of the first through hole 2130. At this point, the expansion member 42 can no longer move axially towards the screw head 431. The connecting assembly 40 then connects the first cabinet 21 and the second cabinet 22, and the first cabinet 21 and the second cabinet 22 are coaxially arranged along the axial direction of the tube 41, ensuring that the first cabinet 21 and the second cabinet 22 are flush. Continuing to drive the screw head 431 to rotate, the expansion member 42 will cause the second cabinet 22 and the first cabinet 21 to move to the same side, thus tightening and merging the first cabinet 21 and the second cabinet 22. In this method, when connecting the first cabinet 21 and the second cabinet 22, a worker passes the connecting component 40 through the first through hole 2130 on the first cabinet 21 and the second through hole 2230 on the second cabinet 22, and then drives the screw head 431 to rotate to realize the connection of the first cabinet 21 and the second cabinet 22. This simplifies the operation process of connecting the first cabinet 21 and the second cabinet 22 and improves the efficiency of connecting multiple cabinets.

[0041] When connecting the first cabinet 21 and the second cabinet 22, the tube 41 can also pass through the second through hole 2230 on the second cabinet 22 and the first through hole 2130 on the first cabinet 21 in sequence. The stud 43 is inserted into the tube 41, and the screw head 431 in the stud 43 can be located on one side of the second cabinet 22. The expansion member 42 is located on one side of the second cabinet 22, and the expansion member 42 is screwed to the second end of the stud body 430 in the stud 43, driving the screw head 431 to rotate. 2 will move along the axial direction of the tube body 41 toward the screw head 431. Since the outer diameter of the expansion member 42 is larger than the inner diameter of the expansion section 410, the expansion member 42 can make the expansion section 410 radially expand during the movement until the outer diameter of the expansion section 410 abuts against the inner wall of the second through hole 2230. Then the expansion member 42 will be unable to continue moving along the axial direction of the tube body 41 toward the screw head 431. At this time, the connecting assembly 40 can also connect the first cabinet 21 and the second cabinet 22.

[0042] When the inner wall of the through hole 421 has internal threads, the inner diameter of the part of the through hole 421 with internal threads is smaller than the inner diameter of the part without internal threads, so as to ensure that when the stud 43 is engaged with the expansion member 42, the inner wall of the expansion member 42 will not obstruct the rotation of the stud.

[0043] The expansion section 410 can have multiple slits 411, and similarly, the expansion member 42 can have multiple protrusions 420. The number of slits 411 on the expansion section 410 can be greater than the number of protrusions 420 on the expansion member 42, as long as one protrusion 420 corresponds to one slit 411. In some embodiments, the number of slits 411 can be the same as the number of protrusions 420, with multiple slits 411 corresponding one-to-one with multiple protrusions 420, and the multiple slits 411 are evenly distributed around the axis of the tube body 41 on the expansion section 410, while the multiple protrusions 420 are evenly distributed on the outer peripheral surface of the expansion member 42. Because the multiple slits 411 are evenly distributed on the expansion section 410, the force on each part of the expansion section 410 is relatively uniform when the expansion section 410 expands under the action of the expansion member 42.

[0044] The expansion section 410 may include a plurality of expansion lobes 412, which may be spaced apart around the axis of the tube body 41, and the distance between two adjacent expansion lobes 412 is the same, and the distance between two adjacent expansion lobes 412 is the gap 411 mentioned above.

[0045] To ensure that the expansion member 42 can gradually expand the expansion section 410 along the axial direction of the tube body 41 as it slides along the expansion section 410, the outer diameter of the expansion member 42 gradually decreases from the first end to the second end of the tube body 41. Thus, as the expansion member 42 slides from the first end to the second end of the tube body 41, the end with the smaller outer diameter will first engage with the expansion section 410 through the cooperation of the protrusion 420 and the gap 411. As the expansion member 42 slides towards the second end of the tube body 41, the relatively larger outer diameter end of the expansion member 42 gradually engages with the expansion section 410, causing the expansion section 410 to gradually expand and abut against the inner wall of the second through hole 2230 in the second cabinet 22 and the inner wall of the first through hole 2130 in the first cabinet 21.

[0046] In the above embodiments, when specifically configuring the expansion section 410, to enhance the stability of the fit between the outer circumferential surface of the expansion member 42 and the expansion section 410, the inner diameter of the expansion section 410 gradually decreases from the first end to the second end of the tube body 41. This gradual decrease in the inner diameter of the expansion section 410 can be understood as the section of the expansion section 410 furthest from the screw head gradually decreasing from the first end to the second end of the tube body 41. Alternatively, it can be considered that the inner guide surface of the expansion section 410 is funnel-shaped from the first end to the second end of the tube body 41, with the larger opening located at the first end of the tube body 41, to mate with the smaller outer diameter end of the expansion member 42, thus facilitating the fit between the expansion member 42 and the expansion section 410.

[0047] When specifically setting the protrusion 420, in order to prevent the protrusion 420 from protruding beyond the largest part of the outer diameter of the expansion member 42, the diameter of the protrusion 420 can be gradually increased from the first end of the tube body 41 to the second end of the tube body 41, so as to ensure that the protrusion 420 can fit with the gap 411, and when fitting with the gap 411, the protrusion 420 will not be exposed outside the expansion section 410.

[0048] Figure 7 for Figure 2 The enlarged view at point A in the middle, continue to refer to... Figure 3 , Figure 5 , Figure 6 and Figure 7The connecting assembly 40 also includes a positioning plate 44. The second end of the tube body 41 is fixedly connected to the positioning plate 44, which extends radially along the tube body 41. The positioning plate 44 and the tube body 41 can be integrally formed, or they can be fixedly connected by welding or bonding. On the surface of the positioning plate 44 used to position the tube body 41, an anti-rotation component 45 can also be provided, meaning the tube body 41 and the anti-rotation component 45 are located on the same side of the positioning plate 44. When the connecting assembly 40 is used to connect the first cabinet and the second cabinet, the tube body 41 passes through the first through hole 2130 and the second through hole 2230. The positioning plate 44 is flush with the third sub-connecting frame 213a of the first cabinet, and the anti-rotation component 45 can pass through the positioning hole 2131 provided on the third sub-connecting frame 213a. The anti-rotation component 45 cooperates with the positioning hole 2131 to prevent the positioning plate 44 from rotating with the stud 43, thereby preventing the tube body 41 from rotating. Furthermore, the rotating component 45, in conjunction with the positioning hole 2131, ensures that the positioning plate 44 will not move relative to the third sub-connecting frame 213a, thus guaranteeing the coaxiality of the tube 41 and the second through hole 2230 connected to the positioning plate 44. Simultaneously, it also ensures the coaxiality of the tube 41 and the second through hole 2230 after the expansion section 410 expands, so that after radial expansion, the outer circumferential surface of the expansion section 410 abuts against the inner wall of the second through hole 2230, thereby ensuring the coaxiality of the first through hole 2130 and the second through hole 2230, and consequently, ensuring that the heights of the first cabinet and the second cabinet are consistent.

[0049] There can be two anti-rotation components 45, which are symmetrically arranged on both sides of the tube body 41. The positioning plate 44 can be provided with multiple mounting holes, which can be countersunk holes. The mounting holes can be used to install the anti-rotation components 45. The multiple mounting holes can be spaced apart along the extension direction of the positioning plate. The arrangement of multiple mounting holes can ensure that at least one mounting hole can be corresponding to the positioning hole 2131 provided on the third sub-connecting frame 213a, and ensure that at least one anti-rotation component 45 can cooperate with the third sub-connecting frame 213a.

[0050] In the above embodiments, the connecting assembly 40 may further include a gasket 46, which is disposed between the screw head 431 and the positioning plate 44. Additionally, the positioning plate 44 may be rectangular, rhomboid, or circular in shape.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
