Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, and not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present utility model.

[0025] Refer to Figures 1 - 5, a UPS power supply for uninterruptible power supply, including a power supply body 1 and a plurality of auxiliary batteries 2. The capacitance of the auxiliary batteries 2 is the same as that of the power supply body 1. At least two rubber pads 3 are bonded to the bottoms of the power supply body 1 and the plurality of auxiliary batteries 2, increasing the friction between the power supply body 1 and the auxiliary batteries 2 and the ground, and at the same time protecting the power supply body 1 and the auxiliary batteries 2 to avoid direct contact and wear between the power supply body 1 and the auxiliary batteries 2 and the ground. Two positioning blocks 4 are integrally formed on one side of each of the plurality of auxiliary batteries 2. Positioning grooves 7 are opened on one side of the power supply body 1 and the plurality of auxiliary batteries 2, and the positioning blocks 4 can be inserted into the positioning grooves 7 to position when the power supply body 1 is connected to the auxiliary batteries 2 and between the auxiliary batteries 2, preventing the auxiliary batteries 2 from rotating. Two card slots 6 are opened on one side of the power supply body 1 and the plurality of auxiliary batteries 2. A first contact 8 is provided on one side of the card slot 6, and the first contact 8 is connected to the card slot 6 through a movable component. A connecting block 5 is provided on one side of each of the plurality of auxiliary batteries 2. A second contact 15 is provided on one side of the connecting block 5, and the first contact 8 is in contact with the second contact 15. A limiting mechanism for assisting in fixing the connecting block 5 is provided on one side of the plurality of card slots 6. When it is necessary to increase the power of the UPS power supply, the auxiliary battery 2 is taken out, and the connecting block 5 on one side of the auxiliary battery 2 is inserted into the card slot 6 to make the first contact 8 contact the second contact 15, thereby completing the electrical connection between the auxiliary battery 2 and the power supply body 1. The auxiliary batteries 2 are also connected in the above manner. After connection, the auxiliary batteries 2 are connected in parallel with the power supply body 1 and between the auxiliary batteries 2, so that the voltage of the storage batteries always remains the same, and thus it can meet the long-term power supply.

[0026] Among them, the movable component includes a sliding hole 12 opened on one side of the card slot 6. The first contact 8 slides in the sliding hole 12. An elastic component that is conductive and pushes the first contact 8 to slide out of the sliding hole 12 is provided between the first contact 8 and the sliding hole 12. The elastic component will squeeze the first contact 8 to slide out of the sliding hole 12, so that the contact between the first contact 8 and the second contact 15 is closer, and thus the stability of the electrical connection between the auxiliary battery 2 and the power supply body 1 and between the auxiliary batteries 2 is ensured. The elastic component is a spring 10. One end of the spring 10 is welded in the sliding hole 12. An avoidance hole 11 is opened on one side of the first contact 8, and the other end of the spring 10 is located in the avoidance hole 11.

[0027] Among them, the limiting mechanism includes an installation groove 16 which is opened on one side of the connecting block 5. A rubber ball 17 is bonded in the installation groove 16. The rubber ball 17 is made of elastic rubber material. A first arc-shaped groove 9 is opened on one side of the card slot 6, and the rubber ball 17 is located in the first arc-shaped groove 9. During the process of the connecting block 5 being inserted into the card slot 6, the card slot 6 will squeeze the rubber ball 17 to deform. When the rubber ball 17 is located at the first arc-shaped groove 9, the squeezed and deformed rubber ball 17 will recover and thus be inserted into the first arc-shaped groove 9 to complete the fixation of the auxiliary battery 2, making the connection between the auxiliary battery 2 and the power supply body 1 and between the auxiliary battery 2 and the auxiliary battery 2 more stable.

[0028] Among them, two protective grooves 14 are opened on one side of each of the multiple auxiliary batteries 2, and the connecting block 5 is rotatably connected in the protective grooves 14. When the auxiliary battery 2 is not in use, the connecting block 5 can be inserted into the protective grooves 14. A second arc-shaped groove 13 is opened on one side of each of the multiple protective grooves 14, and the rubber ball 17 can be located in the second arc-shaped groove 13. During the process of the connecting block 5 being inserted into the protective grooves 14, the protective grooves 14 will squeeze the rubber ball 17 to deform. When the rubber ball 17 is located at the second arc-shaped groove 13, the squeezed and deformed rubber ball 17 will recover and thus be inserted into the second arc-shaped groove 13 to complete the fixation of the connecting block 5, reducing the floor area occupied by the auxiliary battery 2 and being more conducive to the storage of the auxiliary battery 2.

[0029] Working principle: When it is necessary to increase the power of the UPS power supply, take out the auxiliary battery 2, insert the connecting block 5 on one side of the auxiliary battery 2 into the card slot 6 so that the first contact 8 contacts the second contact 15, thereby completing the electrical connection between the auxiliary battery 2 and the power supply body 1. The auxiliary battery 2 and the auxiliary battery 2 are also connected in the above manner. After connection, the auxiliary battery 2 and the power supply body 1 and between the auxiliary battery 2 and the auxiliary battery 2 are all in parallel, so that the voltage of the storage battery always remains the same, and thus it can meet the long-term power supply.

[0030] Finally, it should be noted that: For those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
