BACKGROUND

Technical Field

This disclosure relates to system cabinets, and in particular, to a power cabinet.

Related Art

Power cabinets, as backup power supply systems or electricity recycle systems, are widely applied in many electrical fields.

An existing power cabinet generally includes a cabinet body having a housing and a battery module installed or fixed in the cabinet body. When the power cabinet is produced, the cabinet body is first produced, and then the battery module is inserted into the cabinet body in a manner of pulling a drawer, for installation and fixing. In the foregoing solution, in one aspect, the battery module needs to be pushed into the cabinet body, and is then fixed in another manner such as by using a screw. This increases installation procedures and manual costs in an installation process. In another aspect, cable wiring in the cabinet body is messed up. Besides, cables and the cabinet body are customized according to a quantity of battery modules, which is unhelpful for extension and is inflexible in usage. In addition, production of the cabinet body also requires costs and time.

SUMMARY

This disclosure aims to resolve at least one of the foregoing technical problems to some extent, and provides a power cabinet having a simple installation procedure, low costs, and tidy wiring.

In view of this, this disclosure provides a power cabinet, including: M modules, where the M modules are sequentially stacked from top to bottom; N plug-in components, configured to lead out a power line and/or a signal line; and N locking apparatuses, where a pthmodule and a (p+1)thmodule are electrically connected by using a pthplug-in component, the pthmodule and the (p+1)thmodule are connected by using a pthlocking apparatus, M, N, and p are all integers, M≥3, N=M−1, 1≤p≤M−1, at least one of the M modules is a battery management module, and remaining modules of the M modules are battery modules.

In the power cabinet provided in this disclosure, a cabinet body of a traditional power cabinet does not need to be customized, the M modules are directly stacked from top to bottom to form the cabinet body, the N locking apparatuses are used to assemble and fix the modules, a battery module does not need to be installed and fixed in the cabinet body, an installation procedure is simpler, and costs required to produce the cabinet body are reduced. Besides, the power cabinet provided in this disclosure may be extended according to a requirement, and battery modules may be increased. This is implemented very easily, and more layers may be stacked. However, if the power cabinet having the cabinet body in the prior art needs to be extended, the cabinet body needs to be changed. This results in high costs and a complex procedure. Besides, the N plug-in components lead out the power line or the signal line of the battery module from the battery module, and electrically connect neighboring modules. This reduces cable use complexity and facilitates installation, and cable wiring is tidy and is safer.

REFERENCE NUMERALS

DETAILED DESCRIPTION

The following describes embodiments of this disclosure in detail. Examples of the embodiments are shown in the accompanying drawings, and same or similar reference numerals throughout the accompanying drawings indicate same or similar components or components having same or similar functions. The following embodiments described with reference to the accompanying drawings are exemplary, aim to explain this disclosure, and shall not be understood as limiting this disclosure.

In descriptions of this disclosure, it should be understood that direction or position relationships indicated by terms such as “length”, “width”, “thickness”, “above”, “below”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, and “outside” are direction or position relationships based on the accompanying drawings, and are used only for conveniently describing this disclosure and simplifying descriptions, instead of indicating or suggesting that a represented apparatus or component needs to have a particular direction or is constructed and operated in a particular direction, and therefore shall not be understood as limiting this disclosure. In addition, terms “first” and “second” are used only for description purposes, and shall not be understood as indicating or suggesting relative importance or implicitly indicating a quantity of indicated technical features. Therefore, features modified by “first” and “second” may explicitly or implicitly include one or more features. In descriptions of this disclosure, “multiple” means two or more, unless otherwise defined clearly and specifically.

In this disclosure, unless otherwise clearly specified and defined, terms such as “installation”, “interconnection”, “connection”, and “fixing” shall be understood in a broad sense, for example, may be a fixing connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection by using an intermediate medium, and communication between interiors of two components. A person of ordinary skill in the art may understand specific meanings of the foregoing terms in this disclosure according to a specific situation.

The power cabinet provided in this disclosure includes M modules. The M modules may include a first module, a second module, . . . , an (M−1)thmodule, and an Mthmodule. The first module, the second module, . . . , the (M−1)thmodule, and the Mthmodule are sequentially stacked from top to bottom. The first module is located at the top, and the second module is disposed below the first module. Similarly, a penultimate module is the (M−1)thmodule, and the Mthmodule is located at the bottom. In this disclosure, M may be any integer greater than or equal to 3. For example, inFIG.1, M is 10.

In this disclosure, to facilitate assembly and tidy appearance of the entire power cabinet, the first module, the second module, . . . , the (M−1)thmodule, and the Mthmodule are generally all produced as modules having same appearances and sizes. This can avoid distinguishing the modules in an installation process, and any module may be directly used and stacked without distinguishing whether the selected module satisfies an installation requirement. In this way, the assembly and tidy appearance of the entire power cabinet can be desirably controlled.

In the foregoing, the first module, the second module, . . . , the (M−1)thmodule, and the Mthmodule are sequentially stacked from top to bottom. In this disclosure, it indicates that the first module, the second module, . . . , the (M−1)thmodule, and the Mthmodule are directly stacked and interconnected. The modules are not only interconnected but also in communication connection with each other, including a power connection and/or a signal connection, and the like. As can be predicted, this disclosure provides a power cabinet formed by stacking and interconnecting modules, and a person skilled in the art may add a housing outside the power cabinet, or place the power cabinet in another installation space based on this disclosure without departing from the protection scope of this disclosure.

The power cabinet provided in this disclosure further includes N plug-in components used to lead out the power line and/or the signal line. The N plug-in components include a first plug-in component, . . . , and an Nthplug-in component. N may be any integer greater than or equal to 2. Each plug-in component includes a plug-in female end and a plug-in male end. A person skilled in the art easily understands that the power line and/or the signal line in each module is led out to a plug-in component corresponding to the module, and then the power lines and/or the signal lines in two neighboring modules are connected by using the plug-in component.

In an embodiment of this disclosure, a module of the power cabinet may be a battery module, including a housing and a battery pack disposed in the housing. The battery pack leads out a leading wire, the leading wire is the power line and/or the signal line, and the leading wire is connected to the plug-in component after passing through a line plate. Furthermore, the first plug-in component includes a first plug-in female end and a first plug-in male end. Similarly, the Nthplug-in component includes an Nthplug-in female end and an Nthplug-in male end. In this disclosure, in any case, battery modules used as the second module to the (M−1)thmodule except the first module and the Mthmodule include two plug-in terminals. In this case, a positive pigtail and a negative pigtail of the leading wire of the battery module separately lead out to the two different plug-in terminals. Certainly, the foregoing configuration is only an embodiment of this disclosure. In an actual solution, the first module and the Mthmodule may also include two plug-in terminals, and a specific structure is very easily understood by a person skilled in the art. In an embodiment, all battery modules of the power cabinet have same structures, a plug-in female end is disposed above each battery module, and a plug-in male end is disposed below each battery module. In this way, the power cabinet may be assembled more easily, and extension of the power cabinet is better facilitated.

The leading wire (the power line and/or the signal line) led out from the battery pack is connected to the line plate, and the line plate leads out an output line to electrically connect to a plug-in female end or a plug-in male end above or below the battery module, and to be led out by the plug-in female end or the plug-in male end.

In the power cabinet, a pthmodule and a (p+1)thmodule are electrically connected by using a pthplug-in component, where p is an integer and 1≤p≤M−1. That is, the first module and the second module are electrically connected by using the first plug-in component. That is, the first plug-in component is disposed between the first module and the second module. In the power cabinet shown inFIG.1, the first plug-in component is located between the first module and the second module. The first plug-in component implements a communication and/or electrical connection between the first module and the second module. Similarly, the power cabinet further includes the second plug-in component, . . . , and an (N−1)th plug-in component sequentially disposed from top to bottom. The second plug-in component is located between the second module and the third module. Similarly, a person skilled in the art may very easily understand locations, effects, and functions of the plug-in components. The (M−1)thmodule and the Mthmodule of the power cabinet are electrically connected by using the N plug-in component. That is, the Nthplug-in component is disposed between the (M−1)thmodule and the Mthmodule. The Nthplug-in component implements a communication and/or electrical connection between the (M−1) module and the MO module.

In the power cabinet, the first plug-in component, . . . , and the Nthplug-in component are used, so that the first module, the second module, . . . , the (M−1)thmodule, and the Mthmodule can implement a signal connection and/or an electrical connection more orderly and easily. This can avoid messed wiring in the cabinet body of the power cabinet in the prior art, and improve wiring safety of the power cabinet.

In an embodiment, the power cabinet further includes N locking apparatuses. Each locking apparatus may include a locking female end and a locking male end, and N may be any integer greater than or equal to 2. A pthmodule and a (p+1)thmodule are connected by using a pthlocking apparatus, where p is an integer and 1≤p≤M−1. That is, a first locking apparatus is disposed between the first module and the second module. Similarly, an Nthlocking apparatus is disposed between the (M−1)thmodule and the Mthmodule. The first module and the second module are connected by using the first locking apparatus. Similarly, the (M−1)thmodule and the Mthmodule are connected by using the Nthlocking apparatus. Multiple plug-in components and multiple locking apparatuses are simultaneously disposed to implement a mechanical connection and an electrical connection. The modules are desirably fixed and connected in installation by using the multiple locking apparatuses. In one aspect, this improves installation efficiency, reduces installation costs, and facilitates installation. In another aspect, extensibility of the modules is improved by using the multiple locking apparatuses. Besides, each locking apparatus may have a structure that is detachable or can remove fixed installation. Therefore, extension and maintenance of the power cabinet is better facilitated. In another embodiment, one locking apparatus or multiple locking apparatuses may be disposed between every two modules. For example, four locking apparatuses may be disposed at four corners of the module. This can improve stability of connection between the modules, and usage safety of the entire power cabinet.

In an embodiment, the locking apparatuses may be disposed above and below each of the second module to the (M−1)thmodule. Specifically, a locking female end or a locking male end is disposed above each module, and a locking male end or a locking female end is disposed below each module. Further, the second module to the (M−1)thmodule have completely same structures, and locking apparatuses of the second module to the (M−1)thmodule are also the same. The second module to the (M−1)thmodule may be randomly used or installed without considering a correspondence.

In this disclosure, at least one of the first module, the second module, . . . , the (M−1)thmodule, and the Mthmodule is a battery management module, and remaining modules of the first module, the second module, . . . , the (M−1)thmodule, and the Mthmodule are battery modules.
