DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] The terms "first", "second", etc. in this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] As mentioned above, in order to expand the capacity of the storage device, people usually choose to expand the capacity of the storage particles in a limited space when the space on the circuit board has been almost fully utilized. In the same circuit board space, when the storage capacity of a single storage particle increases, the overall storage capacity of the storage device also increases.

[0022] However, expanding the capacity of storage particles is a very challenging technical problem, which involves multiple levels of complexity and technical requirements. First of all, the structure and properties of the storage particles themselves are extremely delicate, and their internal circuit design and material selection have been rigorously scientifically calculated and experimentally verified. Therefore, when expanding their capacity, it is necessary to ensure that the new storage unit is perfectly integrated with the original structure without any conflict or interference. Secondly, various physical and chemical parameters such as temperature, pressure, electric field, etc. need to be precisely controlled during the expansion process to ensure that the newly added storage unit can work stably. Slight changes in these parameters may have a significant impact on the performance of the storage particles, so technicians are required to have extremely high operating precision and rich experience. Moreover, capacity expansion research is not achieved overnight and requires long-term efforts.

[0023] In summary, the research on storage particle expansion requires not only technical personnel to have profound professional knowledge and a deep understanding of storage technology, but also the ability to master and apply these professional knowledge, rich practical experience, and unremitting innovative spirit, and the ability to continuously innovate and try in the long-term research process. Only by overcoming these problems can we find a suitable expansion plan in the process of experiment and realize the improvement of storage particle capacity.

[0024] Considering the difficulty and cycle of implementing the above expansion scheme, in order to realize the expansion of the storage device more quickly and easily, the present application chooses to increase the circuit board space to realize the expansion of the storage device. Adding a circuit board has higher flexibility and scalability. As one of the core components of the storage device, the circuit board can be customized and expanded according to demand. When the storage capacity needs to be increased, the expansion is achieved by adding additional circuit boards or extending the circuit board. Compared with the complex expansion operation of the storage particles themselves, it is simpler, more convenient and easier to implement. Secondly, compared with the expansion of storage particles, adding a circuit board can provide better performance and stability. Because the expansion of storage particles may involve more physical and chemical parameter control, the change of these parameters may have unexpected effects. As part of the overall system, the circuit board can work better with other components to provide a more reliable data storage and access experience. In addition, adding a circuit board also means better compatibility and standardization. Circuit boards usually use standardized interfaces and protocols, which makes it easier to integrate and connect the added circuit boards when expanding capacity, reducing the trouble caused by compatibility issues.

[0025] However, the circuit board in the storage device is almost the same size as the bottom plate of the storage device housing, and there is no extra space for expansion. Therefore, the present application chooses to utilize the longitudinal space to add an expansion circuit board in a direction perpendicular to the circuit board to achieve the expansion of the storage device, and fix the circuit board to the fastening structure through a fastening structure, which can effectively ensure the structural stability of the circuit board, and is convenient for disassembly and easy to assemble.

[0026] See also Figure 1 , Figure 1 It is a structural diagram of the first embodiment of the storage stacking structure in this application.

[0027] like Figure 1 As shown, the storage stacking structure 100 includes a fastening structure 110 , at least two circuit boards 120 , and a fastener 130 .

[0028] A key hole column 111 is provided on the fastening structure 110, at least two circuit boards 120 are stacked together, and a key hole (not marked in the figure) is provided on each circuit board 120; wherein, the key hole column 111 on the fastening structure 110 passes through the key hole on each circuit board 120, and at least two circuit boards 120 are fixed on the fastening structure 110 by the fastener 130; that is, after the key hole column 111 on the fastening structure 110 passes through the key hole on each circuit board 120, the fastener 130 cooperates with the key hole column 111 on the fastening structure 110, so as to ensure the structural stability between the multiple circuit boards.

[0029] The circuit boards described in the present application may be storage-type circuit boards or other types of circuit boards, wherein one circuit board is a main circuit board and the other circuit boards are sub-circuits, for example, the main circuit board is a storage-type circuit board and the sub-circuit boards are storage-type circuit boards or other types of circuit boards; this embodiment is described by taking the circuit boards as storage-type circuit boards as an example, so as to use the sub-circuit boards as expansion spaces for the main circuit boards. It can be understood by those skilled in the art that when the main circuit board and the sub-circuit boards are storage-type circuit boards, the storage modules in the sub-circuit boards are expanded into storage spaces in the storage circuit boards.

[0030] In some embodiments, the keyhole column may include a plurality of keyhole columns, and the number of corresponding keyholes matches the number of keyhole columns.

[0031] It can be understood that the keyhole column 111 is a hollow structure with a fastening groove in the middle, and the inner diameter of the fastening groove matches the outer diameter of the fastener, so that the fastening groove can just fit the fastener in for fastening connection with the fastener; and the outer diameter of the keyhole column matches the key hole of the circuit board, so that the keyhole column can pass through the key hole.

[0032] In some embodiments, the fastener 130 and the keyhole column 111 can be threadedly matched. For example, the keyhole column is provided with a fastening groove, and an internal thread is provided in the fastening groove, while the fastener 130 is provided with an external thread. When the multi-layer circuit board is fixed on the fastening structure 110, the external thread of the fastener 130 is matched and locked with the internal thread of the keyhole column 111 to achieve the fixation of the multi-layer circuit board.

[0033] In this embodiment, a key hole column is provided on the fastening structure, and the key hole column on the fastening structure passes through the key holes on at least two circuit boards. Through the cooperation of the fastener and the key hole column, at least two circuit boards can be effectively fixed on the fastening structure. While improving the structural stability of the circuit board, the longitudinal space can also be utilized to increase the circuit board in the direction perpendicular to the circuit board to achieve the expansion of the storage device, and the storage space of the storage circuit board can be expanded. There is no need to make process improvements to the storage particles on the storage circuit board. In addition, when the circuit board is damaged, it is easy to disassemble and then replace the circuit board, which is simple and convenient.

[0034] See also Figure 2 , Figure 2 It is a structural diagram of the second embodiment of the storage stacking structure in this application.

[0035] like Figure 2 As shown, at least two circuit boards 120 include a first circuit board 121 and a second circuit board 122. The first circuit board 121 is provided with a first locking hole 1211, and the first circuit board 121 is also provided with at least one first expansion interface; the second circuit board 122 is provided with a second locking hole 1221 and a second expansion interface.

[0036] See also Figure 3 and Figure 4 , Figure 3 is a structural diagram of an embodiment of a first circuit board in this application, Figure 4 It is a structural schematic diagram of an embodiment of the second circuit board in the present application.

[0037] like Figure 3 As shown, the first circuit board 121 includes at least one first expansion interface 1212, a first circuit board plate 1213, a first storage module 1214 and a main control 1215; the main control 1215, the first storage module 1214 and the first expansion interface 1212 are all arranged on the first circuit board plate 1213, and the first lock hole (not marked in the figure) is arranged on the first circuit board plate 1213; the first storage module 1214 is connected to the main control 1215, and the first expansion interface 1212 is located between the main control 1215 and the first storage module 1214.

[0038] like Figure 4 As shown, the second circuit board 122 includes a second expansion interface 1222, a second circuit board plate 1223 and a second storage module 1224; the second expansion interface 1222 and the second storage module 1224 are both arranged on the second circuit board plate 1223, and the second lock hole (not marked in the figure) is also arranged on the second circuit board plate 1223; the second expansion interface 1222 is connected to the second storage module 1224.

[0039] When the first circuit board 121 is expanded, the second expansion interface 1222 is used to expand the first circuit board 121 when the second circuit board 122 is configured on the first circuit board 121. The second expansion interface 1222 is configured to connect a corresponding expansion interface of at least one first expansion interface 1212 in the first circuit board 121 to supplement the second storage module 1224 set in the second circuit board 122 as the storage space of the first circuit board 121.

[0040] In some embodiments, the first storage module 1214 and the second storage module 1224 both include a plurality of storage units, and each storage unit includes a plurality of storage particles.

[0041] The specifications of the storage particles in the storage unit of the second circuit board are the same as those of the storage particles in the storage unit of the first circuit board, and the number of storage particles is also the same. For example, the storage unit on the first circuit board may include 8*5 storage particles, that is, a total of 40 storage particles, arranged in 5 rows, with 8 storage particles distributed in each row; similarly, the storage unit on the second circuit board may also include 8*5 storage particles, so 80 storage particles can be set on the first circuit board; correspondingly, the storage unit of the second circuit board 122 may also include 8*5 storage particles, a total of 80 storage particles; therefore, after the first circuit board 121 is expanded using the second circuit board 122, its storage space is doubled.

[0042] Those skilled in the art will appreciate that by setting the specifications and quantity of the storage units on the second circuit board 122 to be consistent with the specifications and quantity of the storage units on the first circuit board 121, the main control of the first circuit board does not need to change the communication protocol with the storage units, and does not need to make major improvements to the sending of control signals. The storage units on the second circuit board can be controlled directly in accordance with the control method of the storage units on the first circuit board or with reference to the control method of the storage units on the first circuit board.

[0043] The locking column 111 of the fastening structure 110 passes through the first locking hole 1211 of the first circuit board 121 and the second locking hole 1221 of the second circuit board 122 , and the fastener 130 cooperates with the locking column 111 to fix the first circuit board 121 and the second circuit board 122 on the fastening structure 110 .

[0044] The first expansion interface 1212 matches the second expansion interface 1222, and when the first circuit board 121 is expanded, at least one first expansion interface 1212 is configured to connect to the matching second expansion interface 1222 of the second circuit board 122 to supplement the storage module set in the second circuit board 122 as the storage space of the first circuit board 121.

[0045] In some embodiments, at least two first expansion interfaces 1212 of the first circuit board 121 can be set at appropriate positions on the first circuit board 121, one of the first expansion interfaces 1212 is configured to connect to a matching second expansion interface 1222 of the second circuit board 122 to supplement the storage space of the first circuit board 121 with a second storage module set in the second circuit board 122; the other first expansion interface 1212 is configured to connect to the first storage module and the main control on the first circuit board 121.

[0046] The expansion interfaces described in this application are all standardized connection interfaces with expansion capabilities. The user can connect the second circuit board through the expansion interface to use the second storage module in the second circuit board as the storage space of the first circuit board. It can be understood by those skilled in the art that the expansion interface described in this application is a standardized connection interface, which is dedicated to realizing the connection between the storage circuit board (first circuit board) and the matching expansion capacitor board (second circuit board), so as to expand the storage module in the expansion circuit board (second circuit board) into the storage space in the storage circuit board (first circuit board). The storage circuit board (first circuit board) will not be connected to other types of circuit boards through the first expansion interface, for example, other types of circuit boards without storage modules or other types of circuit boards with other functional electronic devices attached.

[0047] The first circuit board 121 of the present application is based on the design of the original storage circuit board, and further, a dedicated and standardized first expansion interface 1212 is further set between the main control and the first storage module. The first expansion interface 1212 is not a traditional external interface (used to realize the connection between the first circuit board 121 and other external devices), one of the first expansion interfaces 1212 is used to realize the expansion application of the original internal signal between the main control and the first storage module of the first circuit board 121 itself, and is connected to the second storage module of the second circuit board 122 through another first expansion interface 1212, and the first lock hole 1211 of the first circuit board 121 and the second lock hole 1221 of the second circuit board 122 are sequentially penetrated through the lock hole column 111 on the fastening structure 110, and the first circuit board 121 and the second circuit board 122 are fixed on the fastening structure 110 through the cooperation of the fastener 130 and the lock hole column 111, so as to improve the structural stability of the circuit board; and enable the second storage module of the matching second circuit board to directly serve as an extension of the storage space of the first circuit board 121 itself, thereby increasing the storage space of the first circuit board 121.

[0048] See also Figure 5 , Figure 5 It is a structural diagram of the third embodiment of the storage stacking structure in this application.

[0049] like Figure 5As shown, the storage stacking structure 100 also includes a connector 140, which is arranged between the first circuit board 121 and the second circuit board 122. The first expansion interface 1212 of the first circuit board 121 and the second expansion interface 1222 of the second circuit board 122 are respectively connected by the connector 140 to realize the connection between the first circuit board 121 and the second circuit board 122, so as to supplement the storage space of the first circuit board 121 with the second storage module arranged in the second circuit board 122.

[0050] A third locking hole 141 is also provided on the connector 140. Therefore, the locking hole column 111 of the fastening structure 110 passes through the first locking hole 1211 of the first circuit board 121, the third locking hole 141 of the connector 140 and the second locking hole 1221 of the second circuit board 122 in sequence, and the first circuit board 121, the connector 140 and the second circuit board 122 are fixed on the fastening structure 110 through the cooperation between the fastener 130 and the locking hole column 111.

[0051] The height of the connector 140 needs to be slightly larger than the sum of the maximum heights of the components provided on the first circuit board 121 and the second circuit board 122 connected to the connector 140. This is to avoid compression or contact between the components on the first circuit board 121 and the second circuit board 122 when the circuit boards are connected through the connector.

[0052] In some embodiments, the connector includes a connector body, a first connection point array, and a second connection point array.

[0053] See also Figure 6 , Figure 6 It is a structural schematic diagram of an embodiment of a connector in the present application.

[0054] like Figure 6 As shown, the connector 140 includes a connector body 142 , a first connection point array 143 , and a second connection point array 144 . There may be a plurality of third locking holes 141 , each of which passes through the connector body 142 .

[0055] The first connection point array 143 is disposed on the first surface of the connector body 142 and includes a plurality of first connection points 1431 . Each first connection point 1431 is configured to be connected to a corresponding first contact in the first expansion interface of the first circuit board 121 .

[0056] The second connection point array 144 is arranged on the second side of the connector body 142, including a plurality of second connection points 1441, each second connection point 1441 being configured to be used for connecting to a corresponding second contact in the second expansion interface of the second circuit board 122, wherein the first side and the second side of the connector body 142 are opposite to each other.

[0057] A plurality of third connection lines 145 are also provided in the connector body 142 , and each first connection point 1431 in the first connection point array 143 is connected to a corresponding second connection point 1441 in the second connection point array 144 via a corresponding third connection line 145 .

[0058] In some embodiments, the first connection point 1431 and the second connection point 1441 protrude from the first surface and the second surface of the connector body 142 , and the first connection point 1431 and the second connection point 1441 are elastically compressible connection points, respectively.

[0059] Elastic compressibility is a special design that has excellent elasticity and compression performance of the connection point. This elastic compressible connection point is usually used in scenarios that require stable and reliable electrical connections, especially in application scenarios that need to withstand compression, vibration or impact. Its design and material selection ensure that the connection point can maintain stable contact with the contact when subjected to external forces, thereby ensuring the stability of data transmission between the first expansion interface and the second expansion interface.

[0060] In one embodiment, the first connection point may be a connection point that does not protrude from the first surface of the connector body, and the second connection point may be a connection point that does not protrude from the second surface of the connector body. The contact connection between the first connection point and the first contact, and the connection contact between the second connection point and the second contact, are achieved by a structure such as locking or pressing between the circuit boards to achieve stable connection contact.

[0061] See also Figure 7 , Figure 7 It is a structural diagram of the fourth embodiment of the storage stacking structure in this application.

[0062] like Figure 7 As shown, the fastening structure 110 in the storage stacking structure includes a bottom plate 112 , a cover plate 113 , a keyhole column 111 and a fastener 130 .

[0063] A key hole column 111 is provided on the base plate 112, and a fourth key hole 1131 is provided on the cover plate 113. The key hole column 111 on the base plate 112 passes through the first key hole 1211, the third key hole 141, the second key hole 1221, and / or part of the fourth key hole 1131. The fastener 130 passes through the fourth key hole 1131, and the first circuit board 121, the connector 140 and the second circuit board 122 are fixed between the base plate 112 and the cover plate 113 through the cooperation between the fastener 130 and the key hole column 111.

[0064] In some embodiments, the diameters of the fourth lock hole 1131 on the cover plate 113 are different on both sides of the cover plate 113, that is, the diameter of the fourth lock hole 1131 on the first side of the cover plate 113 is larger than the diameter of the fourth lock hole 1131 on the second side of the cover plate 113, so that the lock hole column 111 on the base plate 112 can extend into part of the fourth lock hole 1131 of the cover plate 113, but does not penetrate the cover plate; while the fastener 130 can penetrate the fourth lock hole 1131 on the cover plate and extend into the lock hole column 111, and the fastener 130 and the lock hole column 111 can be threadedly matched to fix the first circuit board 121, the connector 140 and the second circuit board 122 between the base plate 112 and the cover plate 113, so that the structure between the circuit boards is stable, and through the first connection point array and the second connection point array of the connector 140, a stable connection contact between the circuit board and the connector is achieved.

[0065] In some embodiments, the diameter of the fourth lock hole 1131 on the cover plate 113 is smaller than the diameters of the first lock hole 1211, the second lock hole 1221 and the third lock hole 141, so that the lock hole column 111 on the base plate 112 cannot pass through the fourth lock hole 1131, that is, the lock hole column 111 on the base plate 112 passes through the first lock hole 1211 of the first circuit board 121, the third lock hole 141 of the connector 140 and the second lock hole 1221 of the second circuit board 122, while the fastener 130 can pass through the fourth lock hole 1131 on the cover plate and extend into the lock hole column 111. The fastener 130 and the lock hole column 111 can be threadedly matched to fix the first circuit board 121, the connector 140 and the second circuit board 122 between the base plate 112 and the cover plate 113, so that the structure between the circuit boards is stable.

[0066] In some embodiments, the base plate can be a rigid substrate and the cover plate can also be a rigid substrate. Then, when the base plate 112 and the cover plate 113 lock the first circuit board 121, the connector 140 and the second circuit board 122, the stress can be dispersed accordingly to reduce the inconsistent stress of the locked middle circuit board, prevent partial warping of the middle circuit board, and maintain the structural stability of the circuit board fastening.

[0067] In this embodiment, the first circuit board, the connector and the second circuit board are fixed by a fastening structure, so that the multi-layer circuit boards can be effectively assembled, and the structural stability of the circuit boards after fastening is ensured, and they are convenient for disassembly and easy for assembly; at the same time, by arranging a connector between the first circuit board and the second circuit board, the first circuit board and the second circuit board also maintain stable contact, and the storage space of the circuit boards can be expanded.

[0070] In some embodiments, the bottom plate of the storage stacking structure 100 is fixedly disposed in the accommodating cavity of the shell 200, so that the storage stacking structure has a stable structure inside the shell, which can effectively avoid the instability of the storage stacking structure caused by the shell tilting or impact, and ensure the stability of the contact between the circuit boards in the storage stacking structure.

[0071] In some embodiments, the housing 200 includes a lower housing 210 and an upper housing 220 , the bottom plate of the storage stacking structure 100 is fixedly disposed on the lower housing 210 , and the upper housing 220 is disposed correspondingly to the lower housing 210 .

[0072] A boss (not marked in the figure) is provided on the inner wall of the upper shell 220, which is arranged corresponding to the key hole column of the fastening structure of the storage stacking structure. There can be multiple bosses (not marked in the figure), which match the number of key hole columns 111, that is, the number of bosses (not marked in the figure) matches the number of fasteners 130; when the upper shell 220 and the lower shell 210 are combined to form a accommodating cavity, the upper shell 220 presses the fastener 130 of the storage stacking structure 100 through the boss, so that the fastener 130 fastens the storage stacking structure 100 in the accommodating cavity of the shell 200.

[0073] In one embodiment, the specification of the housing complies with one of the E3.S specification, the E3.S2T specification, the E3.L specification and the E3.L 2T specification of the network storage.
