[0028] The terms "first", "first", "second", "second" and similar terms used in this utility model do not indicate any order, quantity or importance, but are used to distinguish one component from other components.

[0029] This utility model aims to provide a UPS that can forcibly disconnect the mains power input when replacing batteries. A specially designed door structure prevents the door from being opened, and the batteries from being removed, without first unplugging the mains power cord. This solution reduces the risk of electric shock from the mains when users replace batteries themselves, thereby improving the safety of the device.

[0030] Figures 1 to 3 The UPS according to the present invention is shown as an example. As shown in the figure, the UPS 1 is a box-shaped structure, including a housing 2 and a battery 5 (shown in FIG. Figure 7 The housing 2 is made of a hard metal material and may have a certain reinforcement structure to provide reliable and stable protection for the internal devices.

[0031] The housing 2 includes a shell 3 and a door 4 mounted to the shell 3. The door 4 can move relative to the shell 3 to open the inner cavity of the shell 3 to allow the battery 5 to be introduced into the inner cavity or the battery 5 placed in the inner cavity to be removed. The shell 3 can be a one-piece structure, but in a more preferred embodiment, the shell 3 is designed to be assembled from at least two parts via a detachable connector. Figure 3 An embodiment in which the housing 3 is composed of two parts is shown. In the illustrated embodiment, the housing 3 can be composed of an upper portion 31 and a lower portion 32, wherein the lower portion 32 has a certain depth to form a box-like configuration, and the upper portion 31 is configured as a cover that covers the top of the lower portion 32. In other embodiments, the upper portion 31 and the lower portion 32 can also have the same or substantially the same depth, thereby each being configured as a half-shell structure. The upper portion 31 and the lower portion 32 can be made of the same or different materials. In addition, the upper portion 31 and the lower portion 32 can be removably connected together by any suitable means, such as bolts, latches, or snaps.

[0032] The door 4 is movably mounted to the housing 3. The movement of the door 4 may include linear sliding, rotation, or a combination of sliding and rotation.

[0033] Figures 1 to 3 The door 4 is rotatably mounted to the housing 3, as shown in the exemplary embodiment. To this end, the upper portion 31 of the housing 3 is formed with an upper pivot axis 311 extending toward the lower portion 32, while the lower portion 32 of the housing 3 is formed with a lower pivot axis 321 extending toward the upper portion 31. The upper pivot axis 311 can be, for example, located on the inner surface of the top wall of the upper portion 31, near an edge of the top wall, particularly near the intersection of two adjacent edges of the top wall (e.g., the front edge and a side edge). The lower pivot axis 321 can be, for example, located on the inner surface of the bottom wall of the lower portion 32, similarly to the upper pivot axis 311, near an edge of the bottom wall, particularly near the intersection of two adjacent edges of the bottom wall (e.g., the front edge and a side edge). In the illustrated embodiment, where the lower portion 31 is configured as a box structure having a certain depth, the bottom wall of the lower portion 31 is connected to the side walls at two opposing side edges and to the rear wall at the rear edge. The lower pivot axis 321 can be spaced apart from the adjacent side walls. Thus, the door 4 is mounted on the box structure at the front side of the upper portion 31 and the lower portion 32. When the upper portion 31 and the lower portion 32 are assembled together, the upper pivot shaft 311 and the lower pivot shaft 321 are coaxial. The door 4 is formed with an upper shaft hole 411 at a position corresponding to the upper pivot shaft 311, and a lower shaft hole 412 at a position corresponding to the lower pivot shaft 321, as shown in FIG. Figure 4 and Figure 5As shown. The upper axis hole 411 and lower axis hole 412 of the door 4 are spaced apart, and the upper axis hole 411 is provided with a bottom wall at the end near the lower axis hole 412, while the lower axis hole 412 is provided with a top wall at the end near the upper axis hole 411. When assembling the outer shell 2, the lower axis hole 412 of the door 4 is sleeved onto the lower pivot axis 321 of the lower portion 32 of the shell 3, and the upper pivot axis 311 of the upper portion 31 of the shell 3 is inserted into the upper axis hole 411 of the door 4. The upper portion 31 and the lower portion 32 are then assembled together via a connector, so that the door 4 can be pivotally clamped between the upper portion 31 and the lower portion 32.

[0034] The upper shaft hole 411 and the lower shaft hole 412 can be holes with a circular cross section. Alternatively, as shown in the embodiment, the cross sections of the upper shaft hole 411 and the lower shaft hole 412 are both constructed as waist-shaped holes. The waist-shaped hole is composed of two arc surfaces arranged opposite to each other and two opposite straight surface segments connected between the two arc surfaces. The distance between the two straight surface segments is equal to or slightly larger than the diameter of the upper pivot shaft or the lower pivot shaft accommodated. Thus, the upper pivot shaft 311 and the lower pivot shaft 321 can pivot in the corresponding shaft holes while also performing linear motion along the waist-shaped hole. The two straight surface segments limit the linear motion of the upper pivot shaft and the lower pivot shaft to be performed along one dimension, preventing the upper pivot shaft and the lower pivot shaft from moving during linear motion.

[0035] Those skilled in the art will understand that the upper shaft hole 411 and the lower shaft hole 412 can be appropriately modified as long as they allow the pivotal movement of the upper pivot shaft 311 and the lower pivot shaft 321. For example, the upper shaft hole 411 and the lower shaft hole 412 may each not have a top wall and a bottom wall. Alternatively, the lengths of the upper shaft hole 411 and the lower shaft hole 412 are designed so that when the upper portion 31 and the lower portion 32 of the housing 3 are assembled together, the bottom end of the upper shaft hole 411 can contact the top end of the lower shaft hole 412, thereby forming a docking connection. In other embodiments, a single shaft hole can also be formed on the door, and an upper pivot shaft can be provided only on the upper portion 31, while the lower pivot shaft of the lower portion 32 is omitted, or a lower pivot shaft can be provided only on the lower portion 32, while the upper pivot shaft of the upper portion 31 is omitted.

[0036] The UPS houses batteries within its housing 2 and features a power port on its casing 3 for connecting to the batteries. Power is input by plugging a power cord (such as a mains power cord) into the power port. To ensure that users must unplug the power cord 6 before opening the door 4 and accessing the batteries 5, the door 4 is designed to form a stop along the opening and closing direction when closed, ensuring that the inserted power cord 6 is engaged.

[0037] Specifically, door 4 is formed with a socket 43. When door 4 is closed, the portion of door 4 where socket 43 is formed completely covers the power port of housing 3, leaving only socket 43 aligned with the power port. Therefore, power cord 6 can only be connected to the power port through socket 43. Once power cord 6 passes through socket 43 and connects to the power port, door 4 and power cord 6 form a stop, preventing it from opening. Therefore, to replace battery 5, power cord 6 must first be unplugged to release door 4 and further open the inner cavity of the housing containing battery 5.

[0038] As shown in the embodiment, the lower portion 32 of the housing 3 forms a box structure with a certain depth to facilitate installation of the power interface. Figures 1 to 3 As shown, the lower portion 32 has two opposing side walls and a rear end wall connected between the two side walls. The power interface is mounted on the first of the two side walls of the lower portion 32, away from the rear end wall. The door 4 is connected between the upper portion 31 and the lower portion 32, and is opposite the rear end wall. The door 4 has a first section 41 and a second section 42, wherein the first section 41 and the second section 42 are connected at an angle, for example, at a 90-degree angle. In addition, to adapt to the shape of the housing 2, a circular arc transition section can be connected between the first section 41 and the second section 42 of the door 4. The first section 41 of the door 4 is pivotally mounted to the upper portion 31 and the lower portion 32 near the second of the two side walls, while the second section 42 of the door 4 forms a socket 43. When the door 4 is closed, the second section 42 covers the power interface, leaving the power interface exposed only through the socket 43 for connecting the power cord 6.

[0039] In one embodiment, a portion of the first sidewall of the lower portion 32 where the power interface is mounted can be recessed relative to the remainder of the first sidewall, with the power interface mounted within this recess. When the door 4 is closed, the second section 42 of the door 4 not only covers the recess, aligning the socket 43 with the power interface, but also becomes substantially flush with the remainder of the first sidewall. This gives the housing 2 a smoother, more uniform appearance.

[0040] Door 4 can be connected to the sidewall of housing 3 with a snap-fit ​​connection to ensure stable closure. Alternatively, power cord 6 can be formed with a radially protruding stop surface or stop step. When plugged into the power port, the stop surface or stop step of power cord 6 precisely abuts the periphery of socket 43 of second section 42 of door 4, ensuring a stable stop and keeping door 4 closed.

[0041] Although the figure shows that the door 4 is composed of a first section 41, a second section 42 and a circular arc transition section connected therebetween, it is conceivable that the door 4 may also have other variations to adapt to the position of the power interface. For example, in other embodiments, the power interface is mounted on the housing 3 at the front end, for example, a side wall of the housing 3 forms a front bending section, and the power interface is mounted on the bending section. In this case, the door 4 may have only one plate-like section, and an axial hole is constructed at one end of the plate-like section, while a socket 43 is formed at the other end. When the door 4 is closed, the other end of the plate-like section completely covers the power interface, and the socket 43 is aligned with the power interface. In this case, the door 4 can also be stably maintained in the closed state by means of a radially protruding stop surface or stop step on the power cord 6 against the periphery of the socket 43 of the door 4.

[0042] In addition to a pivotable door 4, other door motion configurations can be designed as needed. For example, in another embodiment, the door can slide linearly relative to the housing. To this end, sliding grooves can be formed in the upper portion 31 and lower portion 32 of the housing 3, respectively. The door can be inserted into the sliding grooves and moved along the grooves to open or close the interior of the housing 31. In this case, the aforementioned radial stop surface or stop step formed on the door 3, aligned with the power interface socket 43 and the power cord 6, is still applicable.

[0043] The following combination Figures 6 to 8 The battery replacement process of the UPS of the present invention is described in detail.

[0044] Figure 6 The UPS in normal state is shown, in which the door 4 is closed and the power cord 6 is connected to the power interface via the socket 43 on the door 4. The door 4 cannot be opened due to the stop of the power cord 6.

[0045] If the battery 5 needs to be replaced, the power cord 6 is first unplugged to allow the door 4 to move relative to the housing 3. When the door 4 moves, the battery 5 in the inner cavity of the housing 3 can be exposed. Figure 7 shown.

[0046] Further references Figure 8 , you can remove the battery 5 for subsequent operations.

[0047] After replacing the battery 5, close the door 4 and connect the power cord 6 through the socket 43 to the power interface to complete the replacement process.

[0048] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0049] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes, modifications and combinations made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
