Description

Technical Field

[0001] This invention relates to the field of battery pack technology, and more specifically to a self-testing uninterruptible power supply. Background Technology

[0002] Some devices have backup power supplies in their power supply circuits. When the mains power is supplied normally, the backup power supply is in a charging state, and when the mains power is cut off, the backup power supply will be activated to ensure that the device is powered on.

[0003] Some existing backup power supplies use multiple individual batteries connected in series. After prolonged use, if one of the individual batteries overheats or short-circuits, it will affect the overall operation of the backup power supply, causing the equipment to lose power and affecting its normal use. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a self-testing uninterruptible power supply, which effectively solves the problem that existing backup power supplies lack protection measures when a single battery experiences high temperature or short circuit.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a self-testing uninterruptible power supply (UPS), comprising a packaging box, a battery pack, and a top cover mounted on the top of the packaging box. The battery pack includes multiple batteries arranged in series, and also includes a heat insulation frame mounted on the same side wall of each battery. Adjacent batteries are connected by connecting plates. A fixing plate is provided on the inner top wall of the top cover, and the fixing plate corresponds one-to-one with the battery. An external connecting plate is provided on the inner side wall of the top cover, and the external connecting plate is electrically connected to an external terminal. An adjustment assembly includes an adjustment frame slidably mounted in the heat insulation frame. Both ends of the adjustment frame are provided with adjustment plates. When the battery is overheated or short-circuited, the adjustment plate rises to connect the connecting plate with the battery electrode. Separate and connect the connecting plate to the fixed plate; end change assembly, including an adjusting tube mounted on the top of the battery, the adjusting tube having multiple adjusting blocks, the adjusting blocks having sliding holes, a movable plate being movably inserted into the sliding holes, and the side wall of the movable plate being slidably mounted on the outer wall of the heat insulation frame, the movable plate having adjusting holes, two heat insulation frames near the edge of the battery pack each having adjusting airbags, the adjusting airbags being connected to the end of the adjusting tube by a connecting tube, multiple piston tubes being provided on one side of the adjusting tube, piston rods being movably inserted into the piston tubes, a conductive frame being rotatably mounted on the end of the piston rod, and a conductive plate being provided on the conductive frame.

[0006] Furthermore, the adjustment assembly also includes a first sliding plate slidably mounted on the inner wall of the heat insulation frame, a second sliding plate slidably mounted on the inner wall of the heat insulation frame and located below the first sliding plate, a strip-shaped airbag connected between the first and second sliding plates, and a return spring connected between the first and second sliding plates. When the battery is at a high temperature, the strip-shaped airbag extends, the first sliding plate moves up and lifts the adjustment frame, and the adjustment frame is U-shaped.

[0007] Furthermore, the adjustment assembly also includes an electromagnet fixedly installed on the inner bottom wall of the heat insulation frame. The electromagnet and the two electrodes of the battery are respectively equipped with conductive rings. Each of the two conductive rings is connected to a conductive rod, and the conductive rod moves through the first slide plate and the second slide plate. Each of the two conductive rods is connected to a capacitor, and both of the capacitors are electrically connected to the electromagnet. A permanent magnet is provided on the bottom wall of the second slide plate, and the electromagnet repels the permanent magnet when energized.

[0008] Furthermore, the connecting plate includes a first overlapping plate and a second overlapping plate that are rotatably connected together, and both the first overlapping plate and the second overlapping plate are made of conductive materials. The sidewalls of the first overlapping plate and the second overlapping plate that are far apart from each other are provided with protrusions.

[0009] Furthermore, a buckle is installed on the side wall of the heat insulation frame, and a buckle hole matching the buckle is provided on the second slide plate, and the buckle hole and buckle are fastened together when the second slide plate moves upward.

[0010] Furthermore, the end-change assembly also includes a sliding conductive sheet slidably mounted on the side wall of the upper cover, with two sliding conductive sheets mounted at two opposite corners of the upper cover. The sliding conductive sheet is in sliding contact with an adjacent external plate, and the sliding conductive sheet is connected to the electrodes of two batteries at the edge of the battery pack. When the sliding conductive sheet moves upward, it disconnects from the batteries.

[0011] Furthermore, a piston disc is slidably provided at the end of the regulating tube, and the piston disc is slidably and sealingly connected to the inner wall of the regulating tube. An adjusting spring for resetting the piston disc is provided in the regulating tube.

[0012] The technical solution provided by this invention has the following advantages compared with the known prior art: This solution includes a heat shield on one side of each battery, and an adjustment component is installed in the heat shield. When a battery in the middle experiences high temperature or short circuit, the connecting plate on that battery is lifted by two adjustment plates, allowing the entire battery pack to skip that battery during operation. When a battery at the edge has a problem, the battery connected to the external plate is replaced using an end replacement component. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] The present invention will be further described below with reference to embodiments.

[0018] Example: Reference Figures 1-11 A self-testing uninterruptible power supply includes a packaging box 1, a battery pack, and a top cover 2 installed on the top of the packaging box 1. The battery pack includes multiple batteries 3 arranged in series and also includes a heat insulation frame 4 installed on the same side wall of each battery 3. Adjacent batteries 3 are connected by a connecting plate 5. The connecting plate 5 includes a first connecting plate 501 and a second connecting plate 502 rotatably connected together. Both the first connecting plate 501 and the second connecting plate 502 are made of conductive materials. The side walls of the first connecting plate 501 and the second connecting plate 502 at opposite ends are provided with protrusions. The inner top wall of the top cover 2 is provided with a fixing plate 28, and the fixing plate 28 corresponds one-to-one with the battery 3. The inner side wall of the top cover 2 is provided with an external connecting plate 29, and the external connecting plate 29 is electrically connected to an external terminal 30.

[0019] like Figure 2 and Figure 5 As shown, this design provides multiple fixing plates 28 on the inner top wall of the upper cover 2. The fixing plates 28 are made of conductive material. The number of fixing plates 28 is the total number of batteries 3 minus two; that is, excluding the two batteries 3 at the edges, each remaining battery 3 has a fixing plate 28 on top. Adjacent batteries 3 are connected in series using connecting plates 5. The connecting plates 5 consist of a first overlapping plate 501 and a second overlapping plate 502 that are rotatably connected. Specifically, the first overlapping plate 501 is connected to the positive terminal of one battery 3, and the second overlapping plate 502 overlaps the negative terminal of another battery 3 (e.g., ...). Figure 2 As shown in the figure, the two batteries 3 located at the edge each have one positive and one negative terminal left, and the positive and negative terminals are connected by external wires.

[0020] Because the fixing plate 28 corresponds one-to-one with the battery 3, that is, the first lap plate 501 on one connecting plate 5 and the second lap plate 502 on another connecting plate 5 are respectively directly below the fixing plate 28, in order to lift the first lap plate 501 and the second lap plate 502 on the battery 3 and make full contact with the fixing plate 28 when the battery 3 has high temperature or short circuit, the battery 3 can be removed from the entire power circuit without affecting the use of other batteries 3 inside the power supply.

[0021] refer to Figures 1-11 The adjustment assembly includes an adjustment frame 8 slidably mounted in the heat insulation frame 4. Both ends of the adjustment frame 8 are equipped with adjustment plates 9. When the battery 3 is at high temperature or short-circuited, the adjustment plates 9 rise to separate the connecting plate 5 from the electrodes of the battery 3 and connect the connecting plate 5 to the fixed plate 28. The adjustment assembly also includes a first sliding plate 6 slidably mounted on the inner wall of the heat insulation frame 4. A second sliding plate 7 is slidably mounted on the inner wall of the heat insulation frame 4, and the second sliding plate 7 is located below the first sliding plate 6. A strip-shaped airbag 10 is connected between the first sliding plate 6 and the second sliding plate 7. A return spring 11 is connected between the first sliding plate 6 and the second sliding plate 7. When the battery 3 is at high temperature, the strip-shaped airbag 10 extends, the first sliding plate 6 moves upward to lift the adjustment frame 8, and the adjustment... The frame 8 is U-shaped. The adjustment assembly also includes an electromagnet 14 fixedly installed on the inner bottom wall of the heat insulation frame 4. Conductive rings 12 are respectively installed on the two electrodes of the electromagnet 14 and the battery 3. Each of the two conductive rings 12 is connected to a conductive rod 13, and the conductive rod 13 moves through the first slide plate 6 and the second slide plate 7. Each of the two conductive rods 13 is connected to a capacitor 16, and each of the two capacitors 16 is electrically connected to the electromagnet 14. A permanent magnet 15 is provided on the bottom wall of the second slide plate 7. When the electromagnet 14 is energized, it repels the permanent magnet 15. A buckle 17 is installed on the side wall of the heat insulation frame 4. The second slide plate 7 is provided with a locking hole that matches the buckle 17, and the locking hole and the buckle 17 are fastened when the second slide plate 7 moves upward.

[0022] In this solution, different measures are taken to address the overheating and short circuit of battery 3: When battery 3 reaches a high temperature due to prolonged use, the strip-shaped airbag 10 contains an evaporating liquid. This liquid evaporates under high temperature, causing the airbag 10 to expand and gradually straighten from a curved shape, thus lifting the first sliding plate 6. As the first sliding plate 6 moves upward, it pushes the upper adjusting frame 8. The upward movement of the adjusting frame 8 causes the two adjusting plates 9 to move upward, lifting the first contact plate 501 and the second contact plate 502 on battery 3 under high temperature conditions (e.g., Figure 11 As shown, the first and second connecting plates 501 and 502 move upwards to fully contact the upper fixing plate 28, thereby disconnecting the battery 3 in its high-temperature state from the entire power circuit. That is, the two batteries 3 on either side of the high-temperature battery 3 are directly connected in series through the upper fixing plate 28, bypassing the high-temperature battery 3. It is worth noting that the high temperature of the battery 3 does not necessarily mean that the battery 3 cannot be used again. Therefore, after the temperature recovers, under the elastic force of the return spring 11, the first sliding plate 6 quickly resets, and the first and second connecting plates 501 and 502 reconnect to the positive and negative terminals of the battery 3. Furthermore, the protrusions on the first and second connecting plates 501 and 502 are elastically installed, which prolongs the connection time between the protrusions and the fixing plate 28 during the reset process of the return spring 11, preventing the entire circuit from being disconnected.

[0023] When battery 3 short-circuits, since conductive ring 12 and conductive rod 13 are connected to the two electrodes of battery 3, and the conductive rod 13 is connected to electromagnet 14 by wires, and capacitor 16 is provided in the circuit, the resistance of capacitor 16 is infinitely large when battery 3 is in normal use, and some electrical energy is stored in capacitor 16, that is, electromagnet 14 is in a de-energized state. When battery 3 short-circuits, the electrical energy in capacitor 16 powers electromagnet 14, electromagnet 14 starts and generates repulsion with permanent magnet 15, second slide plate 7 rises rapidly, second slide plate 7 drives first slide plate 6 to move upward through reset spring 11, the same measures are taken when battery 3 is hot. However, unlike the above high temperature state, when second slide plate 7 moves upward, the buckle 17 and the buckle hole will lock together, so that second slide plate 7 will not reset after moving upward, that is, battery 3 will no longer be connected to the power supply circuit.

[0024] refer to Figures 1-11 The end-change assembly includes an adjustment tube 23 mounted on top of the battery 3. A piston disc 32 is slidably mounted at the end of the adjustment tube 23, and the piston disc 32 is slidably and sealed to the inner wall of the adjustment tube 23. An adjustment spring 33 for resetting the piston disc 32 is provided in the adjustment tube 23. Multiple adjustment blocks 20 are provided on the adjustment tube 23, and sliding holes 27 are provided on each adjustment block 20. A movable plate 19 is movably inserted into the sliding holes 27, and the side wall of the movable plate 19 is slidably mounted on the outer wall of the heat insulation frame 4. Adjustment holes 22 are provided on the movable plate 19. Adjustment airbags 18 are provided in both heat insulation frames 4 near the edge of the battery pack. 18 is connected to the end of the regulating tube 23 by a connecting tube 21. Multiple piston tubes 24 are provided on one side of the regulating tube 23. A piston rod is movably inserted into the piston tube 24. A conductive frame 25 is rotatably installed at the end of the piston rod. A conductive plate 26 is provided on the conductive frame 25. The end change component also includes a sliding conductive piece 31 that is slidably installed on the side wall of the upper cover 2. Two sliding conductive pieces 31 are installed at two opposite corners of the upper cover 2. The sliding conductive piece 31 is in sliding contact with the adjacent external plate 29. The sliding conductive piece 31 is connected to the electrodes of two batteries 3 at the edge of the battery pack. When the sliding conductive piece 31 moves upward, it disconnects from the battery 3.

[0025] The above situation only applies to the batteries 3 other than the two edge batteries 3, because the edge batteries 3 need to be connected to the external board 29, and the external board 29 is connected to the external circuit.

[0026] When a problem occurs with the edge battery 3, whether it's due to high temperature or a short circuit, the two adjusting brackets 8 in the heat insulation bracket 4 on the side of the edge battery 3 move upwards. As the adjusting brackets 8 move the adjusting plate 9 upwards, they also move the sliding conductive sheet 31 on the upper cover 2 upwards, causing the sliding conductive sheet 31 to separate from the electrodes of the edge battery 3. This disconnects the edge battery 3 from the external plate 29. Simultaneously, the upward movement of the adjusting brackets 8 at the edge also presses down on the adjusting airbag 18 and the movable plate 19. Air from the adjusting airbag 18 enters the adjusting tube 23, pressing down the piston disc 32 at the end of the adjusting tube 23. Figure 8 As shown, when the movable plate 19 moves upward, the through hole in the adjusting block 20 aligns with the adjusting hole 22 (the adjusting block 20 has a through hole on its side wall), allowing air from the adjusting airbag 18 to enter the piston tube 24 near the piston tube above the other battery 3 adjacent to the edge battery 3. The piston rod extends, causing the conductive frame 25 and the conductive plate 26 to move, so that the conductive frame 25 contacts the electrode of the battery 3 and the conductive plate 26 makes full contact with the outer plate 29, causing the edge battery 3 to lose connection, and the second battery 3 in sequence becomes the new edge battery 3. This process continues in this manner. If the new edge battery 3 still malfunctions, the corresponding adjustment plate 9 moves upward. The battery 3, originally in the second position, which was connected to the external plate 29 via the conductive frame 25 and conductive plate 26, will be pushed to rotate by the upward movement of the adjustment plate 9. Figure 9 The connection with the external plate 29 is disconnected. The battery 3 at the third position repeats the above steps. When the corresponding movable plate 19 at the battery 3 at the third position moves upward, the through hole in the adjusting block 20 is aligned with the adjusting hole 22. The corresponding piston rod extends, causing the conductive frame 25 and the conductive plate 26 to move. The conductive frame 25 is placed on the electrode of the battery 3 and the conductive plate 26 is in full contact with the external plate 29. Then the battery 3 at the third position becomes the new edge battery 3.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
