Description

Technical Field

[0001] This invention relates to the field of UPS uninterruptible power supply equipment technology, and more particularly to a UPS with replaceable batteries. Background Technology

[0002] UPS, or Uninterruptible Power Supply, is a type of uninterrupted power supply containing energy storage. It is primarily used to provide uninterrupted power to equipment with high power stability requirements. When the mains input is normal, the UPS stabilizes the mains voltage and supplies it to the load; in this state, the UPS acts as an AC voltage regulator while simultaneously charging its internal battery. When the mains power is interrupted (power outage), the UPS immediately switches from the battery's DC power to AC power to the load via an inverter, ensuring the load continues to operate normally and protecting its hardware and software from damage. UPS devices typically provide protection against both overvoltage and undervoltage.

[0003] Most existing UPS power supplies adopt an integrated, non-removable design where the main body and battery are integrated, making it difficult for users to replace or repair the batteries. Furthermore, the batteries in UPS power supplies have a short battery life, making it impossible to replace the batteries without interrupting power during prolonged power outages, thus affecting the continuous and stable power supply performance of the UPS power supply. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a UPS with replaceable batteries.

[0005] The present invention adopts the following technical solution: a UPS with replaceable batteries, including a UPS chassis body, the lower end of the UPS chassis body having a mounting cavity, a battery compartment movably connected to the UPS chassis body being provided in the mounting cavity, a removable auxiliary battery being provided in the battery compartment, a spare battery being detachably connected to the auxiliary battery being provided on the inner wall of the mounting cavity, the spare battery being detachably electrically connected to the auxiliary battery via a first pair of male and female terminals through the battery compartment, the spare battery being detachably electrically connected to the inverter inside the UPS chassis body via a second pair of male and female terminals, and one side wall of the battery compartment being adapted to the opening of the mounting cavity.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the auxiliary battery can be disconnected from the inverter inside the UPS chassis by pulling the battery compartment out of the mounting cavity, and the auxiliary battery can be connected to the inverter inside the UPS chassis by pushing the battery compartment into the mounting cavity. The design of the battery compartment facilitates the user's removal, installation, and replacement of the auxiliary battery. The backup battery is located between the auxiliary battery and the inverter inside the UPS chassis. When a power outage occurs and the auxiliary battery continues to discharge until its power is exhausted, the battery compartment can be pulled out of the mounting cavity to disconnect the auxiliary battery from the inverter inside the UPS chassis. At this time, the backup battery can temporarily supply power to the UPS load until the user pushes the battery compartment with the new auxiliary battery into the mounting cavity, ensuring the continuous and stable power supply of the UPS. The design of the first pair of male and female terminals facilitates the connection between the auxiliary battery and the backup battery without wiring operations. The connection between the auxiliary battery and the backup battery is completed when the battery compartment is pushed into the mounting cavity, making the replacement of the auxiliary battery simpler and more convenient. The design of the second pair of male and female terminals facilitates the connection between the backup battery and the inverter inside the UPS chassis, making it more convenient for the user to replace and maintain the backup battery.

[0007] Furthermore, the opening of the mounting cavity faces forward, and the first pair of male and female terminals includes a first male terminal and a first female terminal. The first female terminal is located on the front inner wall of the battery compartment and is electrically connected to the auxiliary battery. The first male terminal is located on the front side wall of the spare battery and is electrically connected to the spare battery. The spare battery is located on the top inner wall of the mounting cavity.

[0008] Furthermore, the second pair of male and female terminals includes a second male terminal and a second female terminal. The second male terminal is located on the rear side wall of the backup battery and is electrically connected to the backup battery.

[0012] Furthermore, positioning screw holes are provided on both sides of the upper end and the middle of the lower end of the front side wall of the battery compartment. Bolts are installed through the positioning screw holes and embedded in the front side wall of the UPS chassis body to fix the battery compartment to the UPS chassis body.

[0013] Furthermore, a mounting bracket is fixedly provided on the inner wall of the top surface of the mounting cavity. The mounting bracket has a U-shaped cross-section and forms a mounting groove with the top surface of the mounting cavity that is compatible with the backup battery. Connecting ears are provided at both ends of the front sidewall of the backup battery. Connecting holes are provided on the connecting ears.

The spare battery 14 is detachably electrically connected to the auxiliary battery 13 through the battery compartment 12 via a first pair of male and female terminals 15. The spare battery 14 is detachably electrically connected to the inverter in the UPS chassis body 10 via a second pair of male and female terminals 16. One side wall of the battery compartment 12 is adapted to the opening of the mounting cavity 11.

[0032] In this invention, the auxiliary battery 13 can be disconnected from the inverter inside the UPS chassis 10 by pulling the battery compartment 12 out of the mounting cavity 11, and the auxiliary battery 13 can be connected to the inverter inside the UPS chassis 10 by pushing the battery compartment 12 into the mounting cavity 11. The design of the battery compartment 12 facilitates the user's disassembly and replacement of the auxiliary battery 13. The spare battery 14 is located between the auxiliary battery 13 and the inverter inside the UPS chassis 10. When a power outage occurs and the auxiliary battery 13 continues to discharge until its power is exhausted, the battery compartment 12 can be pulled out of the mounting cavity 11 to disconnect the auxiliary battery 13 from the inverter inside the UPS chassis 10. The backup battery 14 provides temporary power to the UPS load until the user pushes the battery compartment 12 with the new auxiliary battery 13 into the mounting cavity 11, ensuring a continuous and stable power supply from the UPS. The design of the first pair of male and female terminals 15 facilitates the connection between the auxiliary battery 13 and the backup battery 14 without the need for wiring operations. The connection between the auxiliary battery 13 and the backup battery 14 is completed when the battery compartment 12 is pushed into the mounting cavity 11, making the replacement of the auxiliary battery 13 simpler and more convenient. The design of the second pair of male and female terminals 16 facilitates the connection between the backup battery 14 and the inverter inside the UPS chassis 10, making it easier for users to replace and maintain the backup battery 14.

[0033] The mounting cavity 11 has its opening facing forward. The first pair of male and female terminals 15 includes a first male terminal 151 and a first female terminal 152.

By setting bolts to pass through the positioning screw holes 125 and embed them into the front side wall of the UPS chassis body 10, the battery compartment 12 is fixedly connected to the UPS chassis body 10. The battery compartment 12 can be effectively fixed by bolts. In this embodiment, the upper edge and lower edge of the opening of the mounting cavity 11 are provided with through holes that are adapted to the positioning screw holes 125.
