[0001] The present invention relates to a backplane assembly kit, an associated removable assembly kit, and an associated electronic device, and more particularly to an improved modular design backplane assembly kit, an associated removable assembly kit, and an associated electronic device. [Background technology]

[0002] Modularity is gradually becoming mainstream in electronic devices. For example, a remote terminal unit is an electronic device installed on-site as a part of a monitoring / control system for monitoring / controlling devices on-site. A remote terminal unit usually includes multiple modules, which may include a power module, a switch module, a computing module, and an input / output module, and a common backplane for mounting multiple modules. However, the conventional remote terminal unit lacks expandability. In addition, the modules and the backplane may easily come off from each other due to environmental vibration. That is, the conventional remote terminal unit is not robust enough to sustain against environmental vibration. Therefore, an improvement is urgently needed. Summary of the Invention [Problem to be solved by the invention]

[0012] According to one embodiment of the invention, the operational component is pivotally arranged on the detachable assembly.

[0013] The pivot axis of the motion component is parallel to the lateral direction and perpendicular to the pivot axis of the latch component.

[0014] According to one embodiment of the invention, the operating component includes an operating portion and a drive portion, the operating portion being operable to move the operating component such that the drive portion drives the latch component to pivot from the locked position to the locked position.

[0015] According to one embodiment of the present invention, a drive structure is formed on the drive portion, and the operating component drives the latch component to pivot from the locked position to the unlocked position by cooperation of the drive structure with a cooperating drive structure formed on at least one end of the latch component.

[0016] According to one embodiment of the invention, the operating component is biased to return by a return component.

[0017] In order to achieve the above object, the present invention further discloses an electronic device. The electronic device includes a backplane assembly, a removable assembly, and a lock assembly. The removable assembly is removably assembled to the backplane assembly. At least one slot is formed in the removable assembly. The lock assembly is disposed between the backplane assembly and the removable assembly, and locks the removable assembly onto the backplane assembly. The lock assembly includes a latch component pivotally disposed on the backplane assembly. At least one end of the latch component is configured to extend into the removable assembly through the at least one slot. The at least one end of the latch component engages with the at least one slot to inhibit the removable assembly from being disengaged from the backplane assembly when the latch component is in a locked position.

[0018] According to one embodiment of the present invention, the locking assembly further includes an operating component movably disposed on the removable assembly and configured to actuate the latch component to pivot from the locked position to an unlocked position and disengage the at least one end of the latch component from the at least one slot to enable removal of the removable assembly from the backplane assembly.

[0024] According to one embodiment of the invention, the locking assembly further includes a resilient component configured to urge the latch component to pivot to the locked position.

[0025] In summary, in the present invention, the latch component is configured to pivotally engage with the slot to inhibit the removable assembly from being removed from the backplane assembly when the latch component is located in the locked position. The above pivotal engagement configuration can effectively inhibit the removable assembly from moving along the lateral, vertical and longitudinal directions relative to the backplane assembly, for example, along the assembly and disassembly direction of the removable assembly relative to the backplane assembly, and can prevent the removable assembly and the backplane assembly from being unintentionally separated due to environmental vibration. That is, the above configuration can provide good sustainability against environmental vibration. In addition, the second module can be assembled to the first module along the lateral direction, thereby realizing the expandability of the electronic device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part of this application and which show, by way of example, specific embodiments in which the invention may be practiced. In this regard, directional terms such as "upper", "lower", "left", "right", "front" and "rear" are used with reference to the orientation of the figures being described. The components of the invention can be oriented in many different directions. As such, the directional terms are used for purposes of explanation and not of limitation. Accordingly, the drawings and description are to be regarded as illustrative in nature and not limiting. Additionally, unless expressly stated, the term "coupled" is intended to mean either an indirect or direct electrical / mechanical connection. Thus, when a first device is coupled to a second device, the connection may be via a direct electrical / mechanical connection or via an indirect electrical / mechanical connection via other devices and connections.

[0029] In addition, when an ordinal number (such as "first," "second," "third," etc.) is used as an adjective before a term, the ordinal number is used (unless expressly specified) merely to distinguish the particular feature from other features described by the same or similar term, and the ordinal number has no other meaning or limiting effect, but is merely a convenient name. For example, a "first device" has such a name merely to distinguish it from, for example, a "second device." Thus, the mere use of the ordinal numbers "first" and "second" before the term "device" does not indicate any other relationship between the two devices, nor does it indicate any other characteristic of either or both of the devices. For example, the mere use of the ordinal numbers "first" and "second" before the term "device" does not (1) indicate that either device comes before or after the other device in order or location, (2) indicate that either device occurs or operates before or after the other device in time, or (3) indicate that either device is superior or inferior in importance or quality to the other device. The mere use of an ordinal number does not define a numerical limitation of the feature identified by the ordinal number. For example, the mere use of the ordinal numbers "first" and "second" preceding the term "apparatus" does not indicate that there are exactly two apparatuses.

[0030] Please refer to Figs. 1 to 4. Figs. 1 and 2 are schematic diagrams of an electronic device 1 according to an embodiment of the present invention, viewed from different viewpoints. Figs. 3 and 4 are exploded views of an electronic device 1 according to an embodiment of the present invention, viewed from different viewpoints. As shown in Figs. 1 to 4, the electronic device 1 is a remote terminal unit detachably mounted on a rail component 2, such as a retractable DIN rail, and the electronic device 1 includes a first module 11, a second module 12, a third module 13, and a fourth module 14. The second module 12 is located between the first module 11 and the third module 13 along the lateral direction LD, and is electrically and structurally connected to the first module 11 and the third module 13. The third module 13 is located between the second module 12 and the fourth module 14 along the lateral direction LD, and is electrically and structurally connected to the second module 12 and the fourth module 14. The electronic device 1 is of an expandable configuration. Of course, in other embodiments, there may be more or fewer modules.

[0031] Specifically, the first module 11, the second module 12, the third module 13, and the fourth module 14 may be a power module, a computing module, a first input / output module, and a second input / output module, respectively. However, the present invention is not limited to this embodiment. For example, in another embodiment, the first module, the second module, the third module, and the fourth module may be one of the first input / output module and the second input / output module, a power module, a switch module, and a computing module.

[0032] As shown in Figures 3 and 4, the first module 11 includes a first backplane assembly 111 and a first removable assembly 112. The first backplane assembly 111 is configured to be removably attached to the rail component 2, for example, by a first lock component L1 movably attached to the first backplane assembly 111. The first removable assembly 112 is removably assembled to the first backplane assembly 111. The first module 11 further includes a first lock assembly 113 disposed between the first backplane assembly 111 and the first removable assembly 112 for locking the first removable assembly 112 to the first backplane assembly 111 to prevent the first removable assembly 112 from being unintentionally separated from the first backplane assembly 111.

[0033] Please refer to FIG. 3 to FIG. 6. FIG. 5 is an exploded view of the first module 11 of the electronic device 1 according to the embodiment of the present invention. FIG. 6 is a partial exploded view of the first module 11 of the electronic device 1 according to the embodiment of the present invention. Specifically, as shown in FIG. 3 to FIG. 6, the first lock assembly 113 includes a first latch component 1131 pivotally disposed on the first backplane assembly 111 and a first operating component 1132 pivotally disposed on the first removable assembly 112. Two ends 1131A, 1131B of the first latch component 1131 are configured to extend into the first removable assembly 112 through two first slots 1121 formed in the first removable assembly 112, respectively. As shown in FIG. 5, the first latch component 1131 is pivotable to be switched between a first lock position and a first unlock position along the direction of the arrow. The pivot axis of the first latch component 1131 is different from the pivot axis of the first operating component 1132. The pivot axis of the first latch component 1131 is substantially perpendicular to the lateral direction LD and the height direction HD, and the pivot axis of the first operating component 1132 is preferably substantially parallel to the lateral direction LD, i.e., the pivot axis of the first latch component 1131 is substantially perpendicular to the pivot axis of the first operating component 1132. When the first latch component 1131 is located in the first lock position, both ends 1131A, 1131B of the first latch component 1131 engage with the two first slots 1121, respectively, to prevent the first removable assembly 112 from coming off the first backplane assembly 111. When the first operating component 1132 is operated to drive the first latch component 1131 and move it from the first locked position to the first unlocked position, both ends 1131A, 1131B of the first latch component 1131 disengage from the two first slots 1121, respectively, so that the first removable assembly 112 can be removed from the first backplane assembly 111.The first latch component 1131 is preferably biased to move to the first locked position by a first resilient component 1133, e.g., a torsion spring, to engage both ends 1131A, 1131B of the first latch component 1131 with the two first slots 1121 when the ends 1131A, 1131B of the first latch component 1131 extend into the first removable assembly 112 via the two first slots 1121. The first operating component 1132 is preferably biased to return by a first return component 1234, e.g., a torsion spring, when the first operating component 1132 is released.

[0034] More specifically, the first latch component 1131 further includes a pivot portion 1131C located between both ends 1131A, 1131B of the first latch component 1131 and pivotally connected to the first backplane assembly 111. The first backplane assembly 111 includes a front cover 1111 and a rear cover 1112. The pivot portion 1131C of the first latch component 1131 is located between the front cover 1111 and the rear cover 1112 of the first backplane assembly 111. Two through holes 1111A are formed in the front cover 1111, and both ends 1131A, 1131B of the first latch component 1131 protrude from the front cover 1111 through the two through holes 1111A and extend into the first removable assembly 112 through the two first slots 1121, respectively.

[0035] 3 to 6, in this embodiment, the first operating component 1132 includes a first operating portion 1132A, a first connecting portion 1132B, and a first driving portion 1132C. The first connecting portion 1132B is located between the first operating portion 1132A and the first driving portion 1132C and is pivotally connected to the first detachable assembly 112, and the first operating portion 1132A operates to pivot the first operating component 1132 to drive the first latch component 1131 to pivot from the first locked position to the first unlocked position by the first driving portion 1132C.

[0036] Please refer to FIG. 5-FIG. 7. FIG. 7 is a diagram of the first latch component 1131 of the electronic device 1 according to an embodiment of the present invention. As shown in FIG. 5-FIG. 7, the first drive structure S11 is preferably formed on the first drive part 1132C. The end 1131B of the first latch component 1131 is formed with a first cooperating drive structure S12 configured to be abutted by the first drive structure S11, and the first operating component 1132 drives the first latch component 1131 to pivot from the first lock position to the first unlock position through cooperation between the first drive structure S11 formed on the first drive part 1132C and the first cooperating drive structure S12 formed on the end 1131B of the first latch component 1131. In this embodiment, the first drive structure S11 and the first cooperating drive structure S12 can be two inclined surfaces. However, the present invention is not limited to this embodiment. A first guide inclined surface S13 is further formed on each of both ends 1131A, 1131B of the first latch component 1131, and the first guide inclined surface S13 abuts against the wall of the corresponding first slot 1121 to drive the first latch component 1131 away from the first unlocked position so that both ends 1131A, 1131B of the first latch component 1131 can be extended into the two first slots 1121, respectively.

[0037] However, the invention is not limited to this embodiment. For example, in another embodiment, only one first slot is formed in the first removable assembly, and only one end of the first latch component extends into the first removable assembly to engage the first slot.

[0038] As shown in FIGS. 1 to 4, the second module 12 includes a second backplane assembly 121 and a second removable assembly 122.

As shown in Figure 8, the second latch component 1231 can be pivoted to switch between a second locked position and a second unlocked position along the arrow direction. The pivot axis of the second latch component 1231 is different from the pivot axis of the second operating component 1232. The pivot axis of the second latch component 1231 is substantially perpendicular to the lateral direction LD and the height direction HD, and the pivot axis of the second operating component 1232 is preferably substantially parallel to the lateral direction LD, i.e., the pivot axis of the second latch component 1231 is substantially perpendicular to the pivot axis of the second operating component 1232. When the second latch component 1231 is located in the second lock position, both ends 1231A, 1231B of the second latch component 1231 engage with the two second slots 1221, respectively, to prevent the second removable assembly 122 from coming off the second backplane assembly 121. When the second operating component 1232 is operated to drive the second latch component 1231 and move it from the second locked position to the second unlocked position, both ends 1231A, 1231B of the second latch component 1231 disengage from the two second slots 1221, respectively, so that the second removable assembly 122 can be removed from the second backplane assembly 121.The second latch component 1231 is preferably biased to move to the second locked position by a second resilient component 1233, e.g., a torsion spring, to engage both ends 1231A, 1231B of the second latch component 1231 with the two second slots 1221 when the ends 1231A, 1231B of the second latch component 1231 extend into the second removable assembly 122 through the two second slots 1221.

As shown in FIG. 8-FIG. 10, the second drive structure S21 is preferably formed on the second drive part 1232C. The end 1131B of the second latch component 1231 is formed with a second cooperating drive structure S22 configured to be abutted by the second drive structure S21, and the second operating component 1232 drives the second latch component 1231 to pivot from the second lock position to the second unlock position through cooperation between the second drive structure S21 formed on the second drive part 1232C and the second cooperating drive structure S22 formed on the end 1231B of the second latch component 1231. In this embodiment, the second drive structure S21 and the second cooperating drive structure S22 can be two inclined surfaces. However, the present invention is not limited to this embodiment. A second guide inclined surface S23 is further formed on each of both ends 1231A, 1231B of the second latch component 1231, and the second guide inclined surface S23 abuts against the wall of the corresponding second slot 1221 to drive the second latch component 1231 away from the second unlocked position so that both ends 1231A, 1231B of the second latch component 1231 can be extended into the two second slots 1221, respectively.

[0043] However, the invention is not limited to this embodiment. For example, in another embodiment, only one second slot is formed in the second removable assembly, and only one end of the second latch component extends into the second removable assembly to engage the second slot.

[0044] As shown in FIGS. 1 to 4, the third module 13 includes a third backplane assembly 131 and two third removable assemblies 132.

[0055] However, the invention is not limited to this embodiment. For example, in another embodiment, only one fourth slot is formed in the fourth removable assembly, and only one end of the fourth latch component extends into the fourth removable assembly to engage the fourth slot.

[0056] The first lock assembly 113, the second lock assembly 123, the third lock assembly 133 and the fourth lock assembly 143 have the same working principle. Taking the second lock assembly 123 as an example, a detailed description of the second lock assembly 123 is given below. Detailed descriptions of the first lock assembly 113, the third lock assembly 133 and the fourth lock assembly 143 are omitted for brevity. Please refer to FIG. 17 to FIG. 20. FIG. 17 and FIG. 18 are partial views of the second module 12 of the electronic device 1 from different perspectives when the second latch component 1231 is located in the second lock position according to an embodiment of the present invention. FIG. 19 and FIG. 20 are partial views of the second module 12 of the electronic device 1 from different perspectives when the second latch component 1231 is located in the second unlock position according to an embodiment of the present invention. When it is desired to remove the second removable assembly 122 from the second backplane assembly 121, the second operating portion 1232A can be operated to drive the second operating component 1232 to drive the second latch component 1231 to pivot from the second locked position shown in Figures 17 and 18 to the second unlocked position shown in Figures 19 and 20 by cooperation of the second drive structure S21 and the second cooperating drive structure S22.

[0057] Please refer to Figures 17, 18, 21 and 22. Figures 21 and 22 are partial views of the second module 12 of the electronic device 1 in different states during assembly of the second removable assembly 122 to the second backplane assembly 121 according to an embodiment of the present invention. As shown in Figures 21 and 22, during assembly of the second removable assembly 122 to the second backplane assembly 121, the abutment of the second guide inclined surfaces S23 of the ends 1231A and 1231B of the second latch component 1231 with the walls of the second slot 1221 can drive the second latch component 1231 to pivot away from the second locking position, allowing both ends 1231A and 1231B of the second latch component 1231 to extend into the second slot 1221, respectively. After both ends 1231A, 1231B of the second latch component 1231 are extended into the two second slots 1221, respectively, the second latch component 1231 can be driven, for example, by a torsion spring, to move from the position shown in FIG. 22 to the second locking position shown in FIG. 17 and FIG. 18 to realize pivotal engagement between both ends 1231A, 1231B of the second latch component 1231 and the two second slots 1221, effectively restraining the second detachable assembly 122 from moving in the lateral, vertical and front-to-rear directions relative to the second backplane assembly 121, for example along the assembly / disassembly direction AD of the second detachable assembly 122 relative to the second backplane assembly 121, and preventing the second detachable assembly 122 from being unintentionally separated from the second backplane assembly 121 due to environmental vibrations.

[0058] Please refer to Fig. 23 and Fig. 24 further. Fig. 23 and Fig. 24 are partial views of a first module 11' of an electronic device 1' according to another embodiment of the present invention, seen from different angles.

[0060] Different from the prior art, in the present invention, when the latch component is in a locked position, the latch component is configured to pivotally engage with the slot to inhibit the removable assembly from being disengaged from the backplane assembly. The above pivotal engagement configuration can effectively inhibit the removable assembly from moving along the lateral, vertical and longitudinal directions relative to the backplane assembly, for example, along the assembly and disassembly direction of the removable assembly relative to the backplane assembly, and can prevent the removable assembly and the backplane assembly from being unintentionally separated due to environmental vibration. That is, the above configuration can provide good sustainability against environmental vibration. In addition, the second module can be assembled to the first module along the lateral direction, thereby realizing the expandability of the electronic device.
