Technical Field

[0001] The invention relates to the technical field of backup power supplies, and in particular to an automatically connected backup power supply. Background Art

[0002] The backup power supply is mainly used to prevent electrical or digital products from powering off or out of power during long-term use. It is used to power electrical equipment or digital products.

[0003] For example, CN201721407733.2 discloses a power supply for electrostatic precipitator, comprising: a step-up transformer with at least two primary coils connected to the AC signal line respectively and secondary coils connected in series, at least two rectifier and filter units, and multiple voltage output terminals; the step-up transformer is used to step up the AC oscillation signal on the AC signal line; the rectifier and filter unit is used to rectify and filter the power supply voltage output by the secondary coil of the connected step-up transformer; the voltage output terminal is used to output two power supply voltages output by at least two step-up transformers to the high-voltage ionization component and the low-voltage adsorption component of the electrostatic precipitator respectively. In order to alleviate the technical problem of low reliability of the power supply for electrostatic precipitator existing in the prior art, the technical effect of improving the reliability of the power supply for electrostatic precipitator is achieved.

[0004] However, after a power outage occurs, the existing backup power supply often needs to be manually connected to enable the backup power supply to continue supplying power, and it is difficult to connect automatically. In addition, in order to ensure the service life of the backup power supply during power supply, it is necessary to carry out dust and moisture-proof treatment, but the existing backup power supply is difficult to achieve automatic dust and moisture-proof treatment to avoid problems such as moisture or heat dissipation during placement or use. Summary of the invention

[0005] Therefore, it is necessary to provide an automatically connected backup power supply to solve the problem that the backup power supply is difficult to automatically connect and preserve.

[0006] To achieve the above-mentioned purpose, the inventor provides an automatically connected backup power supply, comprising: a protective outer shell, a snap-on cover is clamped on the outer right side of the protective outer shell, dustproof components are respectively installed on the left and right sides of the inner side of the protective outer shell, and a receiving component is installed on the inner bottom surface of the protective outer shell; the receiving component includes a fixed seat, and a movable plate is arranged above the fixed seat; the rear end face of the movable plate is fixedly connected to a sliding rod, the front side of the movable plate is clamped with a pressing block, the pressing block is fixedly connected to the front panel of the protective outer shell, a magnet strip is clamped on the inside of the pressing block, and the sliding rod, the movable plate, the pressing block and the magnet strip form an automatic connection structure; an automatic expansion ring is installed on the outside of the dustproof component.

[0007] Furthermore, a backup power supply unit is installed inside the protective outer shell, and a connecting module is connected to the right side of the backup power supply unit. The end face of the connecting module is fixedly connected to a connecting square tube, and the right end of the connecting square tube passes through and is plugged into the right side of the interior of the protective outer shell. The interior of the connecting module is connected to the backup power supply unit through a circuit design, and the interior of the connecting square tube is connected to external electrical equipment that needs to be connected to the backup power supply unit through a circuit.

[0008] Furthermore, a rectangular external slot is provided on the outer right end face of the protective outer shell, a buckle cover is snapped inside the external slot, the buckle cover is buckled on the right end of the connecting square tube, and oblique ventilation slots are provided inside the left and right panels of the protective outer shell.

[0009] Furthermore, a longitudinal slide groove is provided on the front end face of the connecting module, a spring is arranged at the bottom end of the longitudinal slide groove, the top end of the spring is connected to the bottom of the sliding rod, the movable plate is wedge-shaped as a whole and a sliding groove is provided on the front inclined surface, an electric iron core is provided on the rear side of the movable plate, a coil is wound around the outside of the electric iron core, and the rear end of the electric iron core is fixedly connected to the front end face of the connecting module and is connected to the internal circuit of the connecting module.

[0010] Furthermore, a rectangular groove is opened inside the pressing block, and the front end face of the pressing block is fixedly connected to the front panel of the protective outer shell, the magnet bar is movably clamped inside the rectangular groove, the rear end face of the magnet bar is attached to the bottom surface of the sliding groove, and the height of the magnet bar is consistent with the height of the electric iron core.

[0011] Furthermore, one end of the pressing block facing the sliding groove is adapted thereto.

[0012] Furthermore, the receiving component also includes a clamping rod, and T-shaped grooves are opened on the front and rear sides of the interior of the fixed seat. The clamping rod is clamped in the T-shaped groove, and the top of the clamping rod is fixedly connected to the bottom surface of the movable plate. An electric contact rod is arranged inside the fixed seat, and the electric contact rod is connected to the backup power supply and the external electrical equipment to be powered through the circuit.

[0013] Furthermore, the dustproof assembly includes a dustproof cover shell, a fixed tube and an electrically controlled telescopic rod. The dustproof cover shell is buckled on the outside of the ventilation slot, the outer end surface of the dustproof cover shell is fixedly connected to the fixed tube, the electrically controlled telescopic rod is installed inside the fixed tube, a limiting hole is provided inside the fixed tube, and a touch ring is fixedly installed on the outside of the fixed tube, and the touch ring is electrically connected to the controller of the electrically controlled telescopic rod.

The automatic expansion ring is located outside the touch ring and is concentric with the touch ring.

[0016] Different from the prior art, the above technical solution has the following advantages: after the electrical equipment in the present invention is powered off, the external coil of the electric iron core is powered off synchronously, causing the electric iron core to lose its magnetism, and it is impossible to push the magnet bar forward by repelling like magnetic poles. The magnet bar will move backward due to magnetic adsorption, pushing the pressing block to move downward until the magnet bar is adsorbed on the electric iron core. When the pressing block moves downward, it triggers the power contact rod to automatically connect the backup power supply to the electrical equipment, thereby realizing automatic connection of power supply.

[0017] In addition, when the expansion plate is dry, its volume is smallest, making the automatic expansion ring in the smallest diameter position. The automatic expansion ring touches the touch ring and connects the circuit, causing the electric control telescopic rod to extend, and the dust cover shell moves toward the middle to ventilate and dissipate heat inside the protective outer shell. When damp, the expansion plate becomes larger and pushes the automatic expansion ring away from the touch ring, the circuit is disconnected, and the electric control telescopic rod is retracted, driving the dust cover shell to move outward and tightly fit onto the outside of the ventilation slot and the inner wall of the protective outer shell, thereby achieving automatic moisture-proofing.

When the electrical equipment is powered off, the external coil of the electric core 3202 is simultaneously powered off, causing the electric core 3202 to lose its magnetism and be unable to push the magnet bar 34 forward through the repulsion of like magnetic poles. The magnet bar 34 will move backward due to magnetic attraction, pushing the pressing block 33 to move downward along the sliding groove 3201 until the magnet bar 34 is attracted to the electric core 3202. At this time, the magnet bar 34 and the electric core 3202 are in the same straight line, and the pressing block 33 moves downward while triggering the power contact rod 4101 to automatically connect the backup power supply 101 to the electrical equipment.

[0047] One end of the pressing block 33 facing the sliding groove 3201 is adapted thereto, so that the pressing block 33 can move steadily and smoothly along the sliding groove 3201 .

[0048] In the embodiments of the present disclosure, as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 4As shown, a backup power supply unit 101 is installed inside the protective outer shell 1, a connection module 102 is connected below the backup power supply unit 101, a connecting square tube 1021 is fixedly connected to the right end face of the connecting module 102, the right end of the connecting square tube 1021 passes through and is plugged into the right side of the inner part of the protective outer shell 1, the interior of the connecting module 102 is connected to the backup power supply unit 101 through a circuit design, the interior of the connecting square tube 1021 is connected to the external electrical equipment that needs to be connected to the backup power supply unit 101 through a circuit, and when the connecting module 102 is connected, the backup power supply unit 101 can be connected to the external electrical equipment, so that the backup power supply unit 101 can be used to power the electrical equipment to cope with sudden power outages and the like.

The oblique ventilation slots can assist in ventilation and heat dissipation inside the protective outer shell 1. The connecting square tube 1021 is used to protect the external circuit. The snap-fit ​​cover 2 can prevent dust from occurring during transportation of the protective outer shell 1, while preventing damage to the circuit connector inside the connecting square tube 1021.

[0050] In the embodiments of the present disclosure, as shown in the attached Figure 8-Figure 10 As shown, the expansion plate 601 is fixedly connected to the inside of the automatic expansion ring 6, the inner end of the expansion plate 601 is connected to the outer wall of the fixed end of the electric telescopic rod 53, and the expansion plate 601 passes through the inside of the limit hole 5201, and the automatic expansion ring 6 is located on the outside of the touch ring 5202 and is arranged in an array around the center of the touch ring 5202. When the expansion plate 601 is dry, the volume is the smallest, so that the automatic expansion ring 6 is at the smallest diameter position, the automatic expansion ring 6 touches the touch ring 5202 and connects the circuit, so that the electric telescopic rod 53 is extended, and the dust cover 51 moves toward the middle to ventilate and dissipate heat inside the protective outer shell 1. When damp, the volume of the expansion plate 601 increases and pushes the automatic expansion ring 6 away from the touch ring 5202, the circuit is disconnected and the electric telescopic rod 53 is retracted, driving the dust cover 51 to move outward and tightly fit to the outside of the ventilation slot and the inner wall of the protective outer shell 1, realizing automatic moisture-proof.

[0051] As attached Figure 5As shown, a longitudinal groove is provided on the front end face of the connection module 102, a spring is arranged at the bottom end inside the longitudinal groove, the top end of the spring is connected to the bottom of the sliding rod 31, the movable plate 32 is wedge-shaped as a whole and a sliding groove 3201 is provided on the front inclined surface, an electric iron core 3202 is provided on the rear side of the movable plate 32, a coil is wound around the outside of the electric iron core 3202, the rear end of the electric iron core 3202 is fixedly connected to the front end face of the connection module 102 and connected to the internal circuit of the connection module 102, when there is a sudden power outage, etc., the circuit of the electric iron core 3202 is disconnected and loses its magnetism, so that the magnetic adsorption magnet strip 34 can be used to move and realize automatic connection to the backup power supply 101 for power supply, when the electrical equipment is in normal use, the external coil of the electric iron core 3202 is energized and has magnetism, so that the position of the magnet strip 34 can be kept at the front side at all times, and the spring pushes the sliding rod 31 to maintain the topmost high position, ensuring that the electrical equipment operates normally while the backup power supply 101 is not used for power supply.

[0052] In the embodiments of the present disclosure, as shown in the attached Figure 5 and attached Figure 6 As shown, the receiving component 4 also includes a clamping rod 42, and T-slots are provided on the front and rear sides of the interior of the fixed seat 41. The clamping rod 42 is clamped in the T-slot, and the top of the clamping rod 42 is fixedly connected to the bottom surface of the movable plate 32. The interior of the fixed seat 41 is provided with a power connection contact rod 4101, and the power connection contact rod 4101 is connected to the backup power supply component 101 and the external electrical equipment to be powered through the circuit. When the power connection contact rod 4101 is pressed downward, the backup power supply component 101 is connected to the external electrical equipment circuit, thereby realizing automatic connection of power supply. The clamping rod 42 is slid in the T-slot to ensure that the movable plate 32 moves straight up and down, which can trigger the power connection contact rod 4101 to connect the power.

[0053] The contact rod 4101 is located between the two T-slots, so that the contact rod 4101 is subjected to a balanced extrusion force.

[0054] In the embodiments of the present disclosure, as shown in the attached Figure 7 , Attachment Figure 8 and attached Fig. 9 As shown, the dustproof assembly 5 includes a dustproof cover shell 51, a fixed tube 52 and an electrically controlled telescopic rod 53. The dustproof cover shell 51 is buckled on the outside of the ventilation slot, the outer end face of the dustproof cover shell 51 is fixedly connected to the fixed tube 52, the electrically controlled telescopic rod 53 is installed inside the fixed tube 52, a limiting hole 5201 is provided inside the fixed tube 52, and a touch ring 5202 is fixedly installed outside the fixed tube 52, the touch ring 5202 is electrically connected to the controller of the electrically controlled telescopic rod 53, when the touch ring 5202 is connected to the automatic expansion ring 6, the circuit is connected and the electrically controlled telescopic rod 53 is started to extend through the controller, the moving end of the electrically controlled telescopic rod 53 pushes the dustproof cover shell 51 to move inward, thereby increasing the distance from the ventilation slot, so that the inside of the protective outer shell 1 can be ventilated and heat dissipated.

[0055] Embodiment 2, on the basis of embodiment 1, the automatic expansion ring 6 can be replaced by an electrically controlled temperature and humidity sensor and electrically connected to the controller of the electrically controlled telescopic rod 53. When the temperature and humidity sensor detects the temperature and humidity inside the protective outer shell 1, the electrically controlled telescopic rod 53 is automatically extended and retracted by the controller, thereby driving the dust cover shell 51 to move, thereby automatically controlling the opening and closing of the ventilation slots, and achieving the purpose of automatic dust and moisture prevention.

[0056] The working principle of this embodiment is as follows: after the electrical device is connected to the circuit inside the connecting square tube 1021, the circuit connection is completed. When the electrical device is running, the outer coil of the electric iron core 3202 is energized and has magnetism, so that the position of the magnet bar 34 can always be kept at the front side, and the spring pushes the sliding rod 31 to maintain the topmost high position, ensuring that the electrical device operates normally while the backup power supply unit 101 is not used for power supply;

[0057] After the electrical equipment is powered off, the external coil of the electric core 3202 is simultaneously powered off, causing the electric core 3202 to lose its magnetism and be unable to push the magnet bar 34 forward through the repulsion of like magnetic poles. The magnet bar 34 will move backward due to magnetic adsorption, pushing the pressing block 33 to move downward along the sliding groove 3201 until the magnet bar 34 is adsorbed onto the electric core 3202. When the pressing block 33 moves downward, it triggers the power contact rod 4101 to automatically connect the backup power supply 101 to the electrical equipment, thereby realizing automatic connection of power supply.

[0058] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
