Description

Technical Field

[0001] This utility model relates to the field of power module equipment technology, specifically to a rail-type plug-in locking device for power modules. Background Technology

[0002] Currently, how to achieve efficient, stable, and easy-to-operate installation and replacement of power modules in conventional network cabinets or power control cabinets is a technical problem that urgently needs to be solved during the installation and use of power modules.

[0003] In the existing technology, the power module is mostly installed using the traditional fixed installation method, that is, the cover and the module body are connected by multiple bolts. The traditional mode is to fix the cover to the module body with four screws, which are located at the four corners of the cover. This will cause the stress on the cover to be relatively concentrated.

[0004] However, this installation method has significant drawbacks. Because the screws are concentrated at the four corners of the cover, the stress on the cover is relatively concentrated. During long-term use of the power module, this stress concentration can easily cause the cover to deform, which not only affects the normal use of the power module but also greatly shortens the lifespan of the cover, increasing equipment maintenance costs and replacement frequency. Utility Model Content

[0005] In view of this, the present invention provides a rail-type plug-in locking device for power modules. The present invention can disperse the stress distribution on the cover plate by screws while quickly disassembling and assembling the cover, thereby indirectly preventing the cover from deforming and increasing the service life of the cover.

[0006] To solve the above-mentioned technical problems, this utility model provides a rail-type plug-in locking device for power modules, including a module body and a cover. The cover is fixed to the module body by two fasteners. A movable plate is hinged to the side of the cover. The movable plate is a cuboid plate structure. After the movable plate is rotated, one side of it can be on the same horizontal plane as the end face of the cover away from the module body. A connecting plate is provided on the horizontal plane of the movable plate. The connecting plate can fit against the end face of the cover away from the module. The connecting plate and the movable plate are arranged in an L-shape. A screw is rotatably provided on the connecting plate. The movable plate can be fixed to the end of the module body by the screw. The stress applied by the screw can be distributed to the hinge of the movable plate through the movable plate.

[0007] The movable plate has two through holes, which are symmetrically arranged on both sides of the cover. The movable plate is rotatably mounted in the movable holes.

[0008] A threaded hole is provided on the side end face of the cover, and a bolt is fixed in the threaded hole. A corresponding connecting hole is provided on the movable plate. The bolt is inserted into the connecting hole to provide support for the movable plate. The movable plate can rotate around the bolt axis as the center.

[0009] The cover is also provided with a relief groove on the side end face. The relief groove is connected to the threaded hole, and the end of the bolt can be placed in the relief groove to make the structure more compact.

[0010] Both sides of the module body are provided with sliding grooves that are connected to the inside of the power module. The sliding grooves facilitate heat dissipation of the module body. Corresponding to the sliding grooves, there are also sliding rails that slide along the sliding grooves and are placed on both sides of the module body. After the sliding rails slide, they can cover the sliding grooves or expose part of the sliding grooves. When covered, the internal heat can be discharged outward through the gap between the sliding rails and the external dust is not easy to enter the module body. At the same time, when the sliding grooves are exposed, it is easy to clean the exposed part.

[0011] The end of the movable plate away from the connecting plate also has an extension. Corresponding to the extension, there is also a movable space at the end of the module body. The extension on the movable plate can rotate within the movable space. The end of the extension away from the connecting plate on the movable plate also has a slot. Corresponding to the slot, there is also a block at the end of the inner wall of the slide rail. The block can be embedded in the slot to indirectly limit the slide rail, so that the slide rail will not slide on the side of the module body when the cover is in a fixed state.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. Quick assembly / disassembly and stress dispersion:

[0014] The stress applied by the screw is dispersed to the hinge through the movable plate, which effectively avoids the deformation of the cover caused by stress concentration, significantly improving the service life and structural reliability of the cover. At the same time, the movable plate and L-shaped connecting plate structure with hinges on the side of the cover, together with the rotating screw for fixing, enable quick assembly and disassembly of the cover.

[0015] 2. Modular and compact design:

[0016] The movable panel is hinged to the cover via movable holes, and combined with the support structure of bolts and connecting holes, the overall size of the device is compact, adapting to the compact space requirements of conventional network cabinets or power control cabinets. The design of the clearance slot further optimizes the structural layout and improves space utilization.

[0017] 3. Enhanced earthquake resistance and stability:

[0018] The coordination between the movable plate extension and the main body of the module, as well as the interlocking design of the slot and the slide rail block, ensures the stability of the slide rail when the cover is fixed, effectively preventing the module from loosening or being damaged due to cabinet vibration or impact, and improving the overall vibration resistance of the system.

[0019] 4. Optimized heat dissipation and dust prevention:

[0020] The sliding grooves and rails on both sides of the module body allow for heat dissipation through gaps while preventing external dust from entering when the rails are covered, thus balancing heat dissipation efficiency and equipment protection requirements. Furthermore, the exposed grooves facilitate cleaning, extending the equipment maintenance cycle.

[0021] 5. Ease of operation and reduced maintenance costs:

[0022] Compared to traditional fixed installations that require multiple tools, this invention achieves tool-free quick assembly and disassembly through a plug-in locking structure, significantly shortening installation and replacement time and reducing maintenance costs and manpower requirements.

[0023] 6. Functional integration and structural optimization:

[0024] The component design takes into account multiple functions (such as slide rail, heat dissipation, and locking). Through simulation calculations, the opening ratio and thin wall thickness are optimized. While meeting the heat dissipation requirements, the number of structural parts is reduced, which reflects the modular design principle and improves the overall performance of the product.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figs. 1-4The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0032] This embodiment provides a rail-type plug-in locking device for a power module, such as... Figs. 1-4 As shown: It includes a module body 1 and a cover 2. The cover is fixed to the end of the module body by two fasteners. The cover 2 has a mesh structure, which facilitates heat dissipation for the module body 1. Both sides of the cover 2 are hinged with movable plates 4. The movable plates 4 have a plate-like structure. After the movable plates 4 are rotated, one side can be on the same horizontal plane as the side of the cover 2 away from the module body 1. A connecting plate 5 is also provided on the horizontal plane of the movable plates 4. The movable plates 4 and the connecting plates 5 are arranged in an L-shape. The movable plates 4 can fit against the end face of the cover 2 away from the module body 1. The connecting plates 5 are rotatably equipped with screws 6. The screws 6 are captive screws. That is, by rotating the captive screws 6 through the cover 2 and inserting them into the module body 1, the position of the cover can be reinforced. At the same time, since the screws 6 apply pressure to the cover 2 through the connecting plates 5, the pressure will be partially applied to the side of the cover 2 through the connecting plates 5, thus dispersing the stress on the cover 2.

[0033] Specifically, two movable holes 3 are provided through the cover 2, such as... Figs. 1-4 As shown: Two movable holes 3 are located on both sides of the cover 2. The movable plate 4 is rotatably set in the movable holes 3. When the side of the connecting plate 5 is attached to the cover 2, the movable plate 4 is placed in the movable holes 3, which can save the space occupied by the movable plate 4 and make the structure more compact and exquisite.

[0034] Correspondingly, threaded holes are provided on both sides of the cover, such as... Figs. 1-4 As shown: The threaded hole is connected to the movable hole 3. The threaded hole is used to prevent the bolt 7 from rotating inside the threaded hole. The bolt 7 is also provided with a through hole on the movable plate 4. The bolt 7 is inserted into the through hole and rotated to connect with the movable plate 4. The movable plate 4 can be removed by unscrewing the bolt 7. In this way, the movable plate 4 or the non-removable screw 6 can be disassembled and replaced.

[0035] Preferably, a relief groove 8 is provided on the side end face of the cover body 2 corresponding to the threaded hole. The relief groove 8 is connected to the threaded hole and the relief groove 8 is located on the same axis as the threaded hole, that is, the end of the bolt 7 can be placed in the relief groove 8, thereby avoiding the bolt 7 end from occupying extra space.

[0036] It is worth mentioning that the main body 1 of the module has sliding grooves 10 on both opposite sides, such as Figs. 1-4As shown: The slide groove 10 is connected to the interior of the module, and a slide rail 11 is provided corresponding to the slide groove 10. The slide rail 11 can slide back and forth on the side wall of the module body 1 in conjunction with the slide groove 10. That is, after the slide rail 11 slides, it can cover the slide groove 10 or expose part of the slide groove 10. When the slide rail 11 covers the slide groove 10, the heat inside the module body 1 can be leaked out through the gap between the module body 1 and the slide rail 11. It can also prevent external dust from entering when the slide rail 11 is covered, thus taking into account both heat dissipation efficiency and equipment protection requirements. At the same time, the exposed state of the slide groove 10 is easy to clean, extending the equipment maintenance cycle.

[0037] Correspondingly, the perforation is located in the middle of the movable plate 4. The end of the movable plate 4 away from the connecting plate 5 is also provided with an extension. The side of the extension away from the connecting plate 5 is also provided with a slot 12. The extension is also provided with a movable space on the opposite sides of the module body 1 near the end cover. Thus, when the movable plate 4 is rotated, the extension can rotate within the movable space. The end of the slide rail 11 near the module body 1 is also provided with a locking block, that is, the slide rail 11 covers the slide groove 10. Then, the movable plate 4 is rotated so that the connecting plate 5 is attached to the cover 2. At this time, the extension can rotate accordingly. Thus, the locking block can be embedded in the slot 12. That is, after the cover 2 is fixed, the slide rail 11 is also fixed at the same time. Thus, when the module body 1 is in normal use, the slide rail 11 will not slide on the side of the module body 1.

[0038] Furthermore, both the main body 1 and the slide rail 11 are provided with clearance grooves at the end near the cover 2, which are used to accommodate the hinge structures on both sides of the cover 2.

[0039] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
