Description

Technical Field

[0001] This invention relates to the field of UPS power supply external protection technology, specifically to an assembled UPS power supply external protection device. Background Technology

[0002] A UPS (Uninterruptible Power Supply) is an uninterruptible power supply with an energy storage structure that can continue to provide power to equipment during unexpected power outages. To prevent damage to the UPS from external environmental influences, protective structures can be installed on the outside of the UPS. For example, a UPS protective enclosure disclosed in application number CN202222370267.2 on December 30, 2022, seals the heat dissipation slots with a sealing plate when an accident occurs inside the enclosure, thus sealing the inside of the enclosure and isolating it from the outside air, providing fire extinguishing functionality. Another UPS protective enclosure disclosed in application number CN201721757627.7 on June 22, 2018, provides waterproof and dustproof protection for the UPS, effectively insulates the heat, facilitates heat dissipation, and improves the service life of the UPS.

[0003] The aforementioned and existing protective devices protect the power supply by placing it inside. Using these devices requires stopping the power supply, moving it, and then reinstalling the relevant wiring. This process is cumbersome, and subsequent replacement is inconvenient. The devices lack flexibility and can sometimes interfere with wiring connections. Furthermore, existing elastic protective devices have a single anti-collision buffering direction, typically only providing horizontal or vertical buffering, resulting in poor protection against oblique expansion. Summary of the Invention

[0004] The purpose of this invention is to provide an assembled UPS power supply external protection device to solve the problems mentioned in the background art. Existing protection devices protect the power supply by placing it inside the protection device. When using the protection device, the power supply must be stopped and moved before protection is applied, and the relevant connecting wires on the power supply can be installed. The overall operation is cumbersome, and subsequent replacement of the protection device is relatively inconvenient. The protection device has poor flexibility and may sometimes affect the connection of the wiring harness on the power supply.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figure 1-8This invention provides a technical solution: an assembled UPS power supply external protection device, including a power supply body 1 and a protective mechanism. The protective mechanism is disposed on the outside of the power supply body 1 to provide protection for the power supply. The protective mechanism includes a first protective cover 2 and a second protective cover 3. The first protective cover 2 and the second protective cover 3 are arranged symmetrically about the center line of the power supply body 1. The first protective cover 2 has an inverted "L" shape design. The first protective cover 2 and the second protective cover 3 are connected to each other through a movable docking mechanism, so that the first protective cover 2 and the second protective cover 3 can be assembled on the outside of the power supply body 1 to provide protection. A transverse bonding block 4 is provided on the inner side of the first protective cover 2 and the inner side of the second protective cover 3. The transverse bonding block 4 is attached to the side surface of the power supply body 1, and a first movable block 5 is provided at the outer end of the transverse bonding block 4. The first movable block 5 and the first protective cover 2 and the second protective cover 3 respectively form a left and right sliding structure. A first return spring 6 is sleeved on the inner side of the first movable block 5, and the inner end of the first return spring 6 is connected to a first stop. Plate 7, the first baffle 7 is located outside the transverse bonding block 4, and the first connecting block 9 is fixed inside the first baffle 7. The first enlarged disk 8 is fixed inside the first connecting block 9. The first enlarged disk 8 is located inside the transverse bonding block 4 and forms a sliding connection with the transverse bonding block 4. The first moving groove 10 is opened on the outside of the first connecting block 9. When the first enlarged disk 8 moves inside the transverse bonding block 4, the first connecting block 9 can move in the first moving groove 10. A longitudinal bonding block 17 is provided above the power supply body 1, and a second movable block 18 is provided above the longitudinal bonding block 17. The second movable block 18 forms an up-and-down sliding structure with the first protective cover 2 and the second protective cover 3 respectively. A third return spring 19 is provided on the outside of the second movable block 18. The connection structure between the second movable block 18 and the longitudinal bonding block 17 is the same as the connection structure between the first movable block 5 and the transverse bonding block 4. A buffer pull-back mechanism is installed above the longitudinal bonding block 17 to provide a return force for the first protective cover 2 and the second protective cover 3 after displacement.

[0043] The lengths of the first protective cover 2 and the second protective cover 3 are greater than the length of the power supply body 1, and the bottom positions of the first protective cover 2 and the second protective cover 3 are higher than the bottom position of the power supply body 1, so that they can achieve better protection. The inner surfaces of the horizontal bonding block 4 and the vertical bonding block 17 are made of silicone material to increase the friction between them and the power supply body 1. The left and right sides of the first enlarged disk 8 and the inner side of the first baffle 7 are provided with ball bearings 11 to reduce the friction when the first baffle 7 and the first enlarged disk 8 move. The second baffle 20 is fixed below the second movable block 18, and the second connecting block 21 is fixed below the second baffle 20. The second moving groove 22 is provided on the outer side of the second connecting block 21. The second moving groove 22 is opened on the upper surface of the vertical bonding block 17. The second enlarged disk 23 is fixed below the second connecting block 21. The second enlarged disk 23 is located inside the vertical bonding block 17 and forms a sliding connection with the vertical bonding block 17.

[0044] In use, the first protective cover 2 and the second protective cover 3 can be assembled onto the outside of the power supply body 1 through the movable docking mechanism to provide protection. After assembly, the horizontal bonding block 4 and the vertical bonding block 17 are kept in contact with the power supply body 1 under the action of the first return spring 6 and the third return spring 19, respectively, so that the horizontal bonding block 4 and the vertical bonding block 17 can remain relatively stationary with the power supply body 1. When the first protective cover 2 or the second protective cover 3 is subjected to impact force, the first movable block 5 can move horizontally within the first protective cover 2 and the second protective cover 3 in coordination with the first return spring 6. The second movable block 18 can move horizontally within the first protective cover 2 and the second protective cover 3 in coordination with the third return spring 19 and the third return spring 19. The second movable block 18 moves vertically in coordination with the first movable block 5. When the first movable block 5 moves horizontally, the second connecting block 21 below the second movable block 18 moves within the second moving groove 22. When the second movable block 18 moves vertically, the first connecting block 9 inside the first movable block 5 slides within the first moving groove 10, allowing the first protective cover 2 and the second protective cover 3 to move relative to the power supply body 1 along the direction of the impact force, thus buffering the impact force received by the power supply body 1. Due to the diversity of their movement directions, they can buffer impacts from different directions, providing better protection for the power supply body 1.

[0045] A heat-conducting mechanism is provided on the outer side of the transverse bonding block 4 to absorb and dissipate heat from the power supply body 1. The heat-conducting mechanism includes a heat-absorbing plate 12, a flexible heat-conducting sheet 13, and a heat dissipation plate 14. The heat-absorbing plate 12 is located on the outer side of the transverse bonding block 4 and is in contact with the power supply body 1 to absorb its heat. The flexible heat-conducting sheet 13 is fixed on the outer side of the heat-absorbing plate 12 to conduct heat from the heat-absorbing plate 12. The heat dissipation plate 14 is fixed on the outer side of the first protective cover 2 and the second protective cover 3, and the heat dissipation plate 14 is connected to the heat-absorbing plate 12 through the flexible heat-conducting sheet 13 to dissipate heat from the heat-absorbing plate 12. A fixing plate 15 is provided on the outer side of the heat-absorbing plate 12, and a second return spring 16 is provided on the inner side of the fixing plate 15. The inner end of the second return spring 16 is connected to the heat-absorbing plate 12 to provide an internal thrust for the heat-absorbing plate 12, so that it is tightly attached to the power supply body 1.

[0046] After the first protective cover 2 and the second protective cover 3 are installed, the heat absorption plate 12 can maintain contact with the power supply body 1 under the action of the second return spring 16, so that it can absorb the heat on the power supply body 1. In conjunction with the flexible heat-conducting sheet 13, the heat is transferred to the heat dissipation plate 14 for dissipation, thereby achieving heat dissipation treatment of the power supply body 1 and avoiding the first protective cover 2 and the second protective cover 3 being located on the outside of the power supply body 1 and affecting its original heat dissipation.

[0047] The buffer pull-back mechanism includes a buffer rope 24, a take-up shaft 25, and a torsion spring 26. The buffer rope 24 is fixed below the first protective cover 2 and the second protective cover 3. The take-up shaft 25 is rotatably installed inside the longitudinal bonding block 17, and the lower ends of the take-up shaft 25 and the buffer rope 24 are fixedly connected. The lower end of the buffer rope 24 is wound around the surface of the take-up shaft 25. The torsion spring 26 is installed at the end of the take-up shaft 25 to provide rotational restoring force for the take-up shaft 25.

[0048] When the first protective cover 2 and the second protective cover 3 are impacted and move horizontally, the buffer rope 24 will be pulled to move, causing the buffer rope 24 to unwind on the winding shaft 25, which will drive the winding shaft 25 to rotate. When the winding shaft 25 rotates, the torsion spring 26 stores force to provide buffering. After the subsequent impact disappears, the winding shaft 25 can rotate under the action of the torsion spring 26 to wind up the buffer rope 24 and pull the first protective cover 2 and the second protective cover 3 to reset.

[0049] The active docking mechanism includes a docking block 27, a limiting groove 28, a docking groove 29, a limiting block 30, a fourth return spring 31, a traction rope 32, and a control shaft 33. The docking block 27 is fixed on the right side of the first protective cover 2. The limiting groove 28 is opened on the side of the docking block 27. The docking groove 29 is opened on the left side of the second protective cover 3, and the docking groove 29 and the docking block 27 form a concave-convex fit structure. The limiting block 30 is set inside the docking groove 29, and the left side of the limiting block 30 is designed with an inclined structure. The fourth return spring 31 is set inside the limiting block 30 to provide thrust. The traction rope 32 is fixed inside the limiting block 30 to control the movement of the limiting block 30. The control shaft 33 is rotatably installed inside the second protective cover 3, and the upper end of the control shaft 33 penetrates through the upper surface of the second protective cover 3. The control shaft 33 and the traction rope 32 are fixedly connected. The movement of the limiting block 30 is controlled by the rotation of the control shaft 33.

[0050] After the first protective cover 2 and the second protective cover 3 are spliced ​​together, the limiting block 30 and the limiting groove 28 are connected to fix them together. When it is necessary to disconnect the first protective cover 2 and the second protective cover 3 later, the control shaft 33 can be rotated to wind up the traction rope 32. The traction rope 32 will pull the limiting block 30 to move, and the connection between the limiting block 30 and the limiting groove 28 will be released. Then the docking block 27 can be pulled out from the docking groove 29, realizing the separation of the first protective cover 2 and the second protective cover 3. It is convenient and quick. When it is necessary to assemble it to the outside of the power supply body 1 later, the docking block 27 is inserted into the docking groove 29, so that the limiting block 30 is locked into the limiting groove 28. This fixes the docking block 27 in the docking groove 29, completing the splicing of the first protective cover 2 and the second protective cover 3.
