Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to a mounting bracket for a DC / DC power module. Background Technology

[0002] In the field of electronic equipment, DC-DC power modules are key components for achieving DC voltage conversion. Their stable installation is crucial for the reliable operation of the equipment. As an important component for fixing DC-DC power modules, the rationality of the structural design of the mounting bracket directly affects the installation, maintenance, and overall performance of the power modules.

[0003] In order to accommodate DC-DC power modules of different sizes, many mounting brackets adopt an adjustable clamping structure with movable clamps on both sides of the bracket body. This type of structure can fix power modules of different widths by adjusting the position of the movable clamps, which improves the versatility of the bracket to a certain extent.

[0004] Existing mounting brackets with movable clamps often use bolt fastening to connect the movable clamp to the bracket body. With this connection method, when the movable clamp needs to be removed for power module replacement or maintenance, operators need to use screwdrivers and other tools to unscrew multiple bolts one by one. This disassembly process is not only tedious and time-consuming, but also prone to bolt loss due to the large number of bolts, increasing maintenance costs and management difficulty. Furthermore, repeated tightening of bolts can cause thread wear, reducing connection reliability and affecting the bracket's ability to secure the power module, thus reducing the practicality of the mounting bracket. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a mounting bracket for a DC / DC power module. This bracket solves the problem that when disassembling the movable clamp for power module replacement and maintenance, operators need to use screwdrivers and other tools to unscrew multiple bolts one by one. The entire disassembly process is not only tedious and time-consuming, but also prone to bolt loss due to the large number of bolts, increasing maintenance costs and management difficulty. In addition, repeated tightening of bolts may cause thread wear, reduce the reliability of the connection, affect the fixing effect of the bracket on the power module, and thus reduce the practicality of the mounting bracket.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mounting bracket for a DC / DC power module, comprising a fixed bracket and four sliding seats, each of the four sliding seats being provided with a limit component; The limiting assembly includes a rotating threaded rod sleeve and a clamping plate. Two T-shaped block slots are opened on the outer wall of the sliding seat. Two T-shaped blocks are fixedly connected to one side of the outer wall of the clamping plate. The rotating threaded rod sleeve is rotatably connected to the outer wall of the protrusion on the sliding seat. The sliding seat has a second limiting block groove on the outer wall near the clamping plate. A limiting block is slidably connected inside the second limiting block groove. The clamping plate has a first limiting block groove on one side of the outer wall. A rotating threaded rod is provided inside the second limiting block groove. All four limiting components are mounted on the fixed bracket and used in conjunction.

[0007] Preferably, the clamping plate is L-shaped, and the outer walls of the two T-blocks are slidably connected to the interior of the corresponding T-block grooves; The end of the limiting block near the clamping plate slides to the outside of the second limiting block groove and slides to the inside of the first limiting block groove.

[0008] Preferably, the end of the rotating threaded rod sleeve near the limiting block extends rotatably into the interior of the second limiting block groove; The end of the rotating threaded rod closest to the limiting block is rotatably connected to the outer wall of the limiting block, while the end of the rotating threaded rod furthest from the limiting block is connected to the internal thread of the rotating threaded rod sleeve.

[0009] Preferably, the upper surface of the fixed bracket is provided with four first sliding grooves, the four first sliding grooves are in pairs, and two second sliding grooves are provided on the inner walls of both sides of the fixed bracket. Among them, the four second slide grooves are in groups of two, and the two first slide grooves are respectively connected to the interior of the corresponding second slide groove. Multiple fixing bolt grooves are opened on both sides of the outer wall of the fixed bracket.

[0010] Preferably, the lower outer walls of the L-shaped connecting rods that are slidably connected inside the two sets of first and second slide grooves are respectively fixedly connected to the lower outer wall of the corresponding sliding seat on the side away from the clamping plate. Among them, the upper ends of the L-shaped connecting rods that are slidably connected inside the two sets of first and second slide grooves are all fixedly connected with sliding limit blocks.

[0011] Preferably, the outer walls of the L-shaped protrusions on the four sliding limit blocks are all threaded with fixing bolts; Among them, the ends of the four fixing bolts near the fixing bolt grooves are all threaded to the outside of the L-shaped protrusion and are respectively slidably connected to the inside of the corresponding fixing bolt groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The mounting bracket of this DC / DC power module uses a rotating threaded sleeve in the limiting assembly. Since the rotating threaded sleeve is threadedly connected to the rotating threaded rod, the rotation of the rotating threaded sleeve will drive the rotating threaded rod to make linear motion in the second limiting block groove. The rotation of the threaded rod will then drive the limiting block to slide in the second limiting block groove, causing the limiting block to exit the first limiting block groove of the clamping plate and release the clamping plate from fixation. This makes the disassembly of the clamping plate simple and quick, avoiding the need for workers to remove the bolts one by one, and effectively reducing the workload of workers.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a mounting bracket for a DC / DC power module, including a fixed bracket 1 and four sliding seats 4; Limiting components are provided on all four sliding seats 4; The limiting assembly includes a rotating threaded rod sleeve 8 and a clamping plate 12. The clamping plate 12 is L-shaped. Two T-shaped block grooves 10 are formed on the outer wall of the sliding seat 4. Two T-shaped blocks 9 are fixedly connected to one side of the outer wall of the clamping plate 12. The outer walls of the two T-shaped blocks 9 are slidably connected to the interior of the corresponding T-shaped block grooves 10. The rotating threaded rod sleeve 8 is rotatably connected to the outer wall of the protrusion on the sliding seat 4. A second limiting block groove 15 is formed on the outer wall of the sliding seat 4 near the clamping plate 12. A limiting block 14 is slidably connected inside the second limiting block groove 15. A first limiting block groove 1 is formed on one side of the outer wall of the clamping plate 12. 1. The end of the limiting block 14 near the clamping plate 12 slides to the outside of the second limiting block groove 15 and slides to the inside of the first limiting block groove 11. The end of the rotating threaded rod sleeve 8 near the limiting block 14 rotates to the inside of the second limiting block groove 15. The inside of the second limiting block groove 15 is provided with a rotating threaded rod 13. The end of the rotating threaded rod 13 near the limiting block 14 is rotatably connected to the outer wall of the limiting block 14. The end of the rotating threaded rod 13 away from the limiting block 14 is threadedly connected to the inside of the rotating threaded rod sleeve 8. All four limiting components are set on the fixed bracket 1 and used in conjunction.

[0020] The fixed bracket 1 has four first sliding grooves 2 on its upper surface, which are arranged in pairs. The inner walls of both sides of the fixed bracket 1 have two second sliding grooves 3, which are arranged in pairs. The two first sliding grooves 2 communicate with the interior of the corresponding second sliding grooves 3. The outer walls of both sides of the fixed bracket 1 have multiple fixing bolt grooves 6. The lower outer walls of the L-shaped connecting rods that are slidably connected inside the two sets of first sliding grooves 2 and second sliding grooves 3 are fixedly connected to the lower outer walls of the corresponding sliding seats 4 on the side away from the clamping plate 12. The upper ends of the L-shaped connecting rods that are slidably connected inside the two sets of first sliding grooves 2 and second sliding grooves 3 are fixedly connected to sliding limit blocks 7. The outer walls of the L-shaped protrusions on the four sliding limit blocks 7 are threaded with fixing bolts 5. The ends of the four fixing bolts 5 that are close to the fixing bolt grooves 6 are threaded to the outside of the L-shaped protrusions and are slidably connected to the interior of the corresponding fixing bolt grooves 6.

[0021] Furthermore, when using this device, firstly, when installing the DC-DC power module, adjust the position of the four sliding seats 4 according to the module size by sliding the L-shaped connecting rod within the first and second sliding grooves 2 and 3 of the fixed bracket 1, so that they can surround the four corners of the power module. After the position is determined, tighten the fixing bolts 5 on the sliding limit block 7, screw the fixing bolts 5 into the fixing bolt grooves 6 of the fixed bracket 1, and lock the position of the sliding seats 4. At this time, the clamping plate 12 is fixed to the sliding seat 4 by the limit block 14. Directly push the "L"-shaped clamping plate 12 so that it slides within the T-shaped block groove 10 through the T-shaped block 9 until the clamping plate 12 is in close contact with the edge of the DC-DC power module, thus completing the clamping and fixing of the power module. When it is necessary to remove the clamping plate 12, operate the limit block... The positioning component rotates the threaded sleeve 8. Since the threaded sleeve 8 is threadedly connected to the threaded rod 13, the rotation of the threaded sleeve 8 will cause the threaded rod 13 to move linearly within the second limiting block groove 15. The rotation of the threaded rod 13 will then cause the limiting block 14 to slide within the second limiting block groove 15, causing the limiting block 14 to exit the first limiting block groove 11 of the clamping plate 12, thus releasing the clamping plate 12 from its fixation. At this time, the clamping plate 12 can slide freely within the T-shaped block groove 10 via the T-shaped block 9, removing it from the DC-DC power module and completing the disassembly of the clamping plate 12. The DC-DC power module can then be removed. When reinstalling, the limiting component is operated in reverse so that the limiting block 14 is reinserted into the first limiting block groove 11 to fix the clamping plate 12 for subsequent use.

[0022] By rotating the threaded sleeve 8 in the limiting assembly, since the threaded sleeve 8 is threadedly connected to the threaded rod 13, the rotation of the threaded sleeve 8 will drive the threaded rod 13 to make linear motion in the second limiting block groove 15. The rotation of the threaded rod 13 will then drive the limiting block 14 to slide in the second limiting block groove 15, so that the limiting block 14 exits the first limiting block groove 11 of the clamping plate 12, releasing the fixation of the clamping plate 12. In this way, the disassembly of the clamping plate 12 is simple and quick, avoiding the need for workers to disassemble the bolts one by one, effectively reducing the workload of the workers.

[0023] Structural Description: Fixed Bracket 1: As the basic load-bearing component of the entire mounting bracket, four first sliding grooves 2 are opened on its upper surface to guide the L-shaped connecting rod to slide. The second sliding grooves 3 on both inner walls are connected to the first sliding grooves 2 to further enhance the sliding stability. Multiple fixing bolt grooves 6 on both outer walls, together with fixing bolts 5, fix the sliding limit block 7, thereby locking the position of the sliding seat 4 and providing a stable platform for the installation of the DC-DC power module. Sliding seat 4: There are four in total. They serve as the mounting carrier for the limiting components. They are connected to the first and second sliding grooves of the fixed bracket 1 via L-shaped connecting rods to achieve position adjustment. The T-shaped block groove 10 and the second limiting block groove 15 on the outer wall provide installation and movement space for the clamping plate 12 and the limiting components. Fixed bolt 5: It is threaded to the L-shaped protrusion of the sliding limit block 7. One end can be screwed into the fixed bolt groove 6 of the fixed bracket 1. After tightening, the sliding limit block 7 and the connected sliding seat 4 are fixed on the fixed bracket 1 to prevent the sliding seat 4 from shifting during use. Sliding limit block 7: Installed on the upper end of the L-shaped connecting rod, its L-shaped protrusion is used to install the fixing bolt 5. By fixing it with the fixing bracket 1, it restricts the sliding of the L-shaped connecting rod, thereby fixing the sliding seat 4 and ensuring the stability of the limit component and the DC-DC power module. Rotating threaded rod sleeve 8: Rotarily connected to the outer wall of the protrusion of the sliding seat 4, one end of which extends into the second limiting block groove 15 and is threadedly engaged with the rotating threaded rod 13. By rotating the rotating threaded rod sleeve 8, the rotating threaded rod 13 is moved by the threaded transmission, thereby controlling the limiting block 14 to disassemble the clamping plate 12. T-block 9: Two T-blocks 9 are fixed on one side of the clamping plate 12 and slide in cooperation with the T-block groove 10 of the sliding seat 4, so that the clamping plate 12 can slide smoothly on the sliding seat 4 to realize the clamping action of the DC-DC power module, and at the same time, it is easy to detach during disassembly. Clamping plate 12: It is L-shaped and connected to sliding seat 4 through T-block 9. It is used to directly clamp DC-DC power module. Its position is fixed by the cooperation of limiting block 14 and first limiting block slot 11. It needs to be operated with the help of limiting components when disassembling. Rotating threaded rod 13: placed in the second limiting block groove 15, one end is rotatably connected to the limiting block 14, and the other end is threadedly connected to the rotating threaded rod sleeve 8. Under the drive of the rotating threaded rod sleeve 8, the limiting block 14 is driven to slide in the second limiting block groove 15, thereby fixing or disassembling the clamping plate 12. Limiting block 14: It is slidably connected in the second limiting block groove 15, and one end can extend out of the groove and be inserted into the first limiting block groove 11 of the clamping plate 12 to fix the clamping plate 12. When disassembling, it is driven by the rotating threaded rod 13 to exit the first limiting block groove 11, so that the clamping plate 12 can be freely slidably disassembled.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
