Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0031] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0032] In one embodiment of the present invention, see the attached Figure 1 , provides an emergency drive device compatible with DC power supply, including an emergency AC input port, a drive input port, an emergency DC input port, an emergency drive AC-DC module, a drive input control module, a voltage conversion module, a charging management module, a battery pack, and a DC-DC module; the output end of the emergency AC input port is connected to the input end of the emergency drive AC-DC module; the output end of the emergency drive AC-DC module is connected to the input end of the drive input control module; the output port of the emergency drive AC-DC module is connected to the input end of the charging management module; the output end of the emergency DC input port is connected to the input end of the voltage conversion module; the output end of the charging management module is connected to the input end of the battery pack; the output end of the battery pack is connected to the input end of the DC-DC module; the output end of the DC-DC module is connected to a load.

[0033] Under normal working conditions, the emergency AC input port is connected to 220V AC (mains power), the emergency AC input port is connected to 220V AC, the output end of the emergency drive AC-DC module supplies power to the drive input control module, the drive input control module controls the drive output module to output voltage to the DC-DC module, and then supplies power to the load; the emergency drive AC-DC module also supplies power to the charging management module, and then charges the battery pack.

[0034] In an emergency situation, the emergency AC input port is in a state of no input power (no AC power input), the emergency drive AC-DC module is powered off, the battery pack supplies power to the DC-DC module, and the DC-DC module converts the power to the load.

[0035] In an emergency situation, when the emergency AC input port has no input power (no AC power input), the emergency DC input port can also be used to connect to an external DC power supply. The output end of the emergency DC input port is connected to the input end of the voltage conversion module, and the DC power of the external DC power supply is converted through the voltage conversion module to the DC-DC module, thereby supplying power to the load.

[0036] The voltage conversion module is used to increase or decrease the DC voltage provided by the external DC power supply to a working voltage suitable for the DC-DC module.

[0037] The charging management module is used to obtain the charging voltage of the battery pack, control the charging voltage when the AC-DC module is in the power supply state, and charge the battery pack; the battery pack is an external battery or a battery pack built into the emergency drive device, and the battery of the battery pack is a rechargeable battery, which can be a lithium battery.

[0038] When using the emergency drive device compatible with DC power supply of the utility model, under normal lighting conditions, the AC-DC module supplies power to the relay, and the relay controls the drive output module to output voltage to the DC-DC module, thereby supplying power to the load; the AC-DC module is energized with the charging management module, and the charging management module charges the battery pack.

[0039] In an emergency situation, the AC-DC module loses power and cannot provide power to the relay. At this time, the battery pack outputs voltage to the DC-DC module, which in turn supplies power to the load.

[0040] In an emergency, an external DC power supply can also supply power through the DC input port, and the voltage conversion module outputs voltage to the DC-DC module, thereby supplying power to the load.

[0041] Therefore, the driving device of the utility model can supply power to the load through the battery pack or through an external DC power supply in the absence of normal power input, and can supply power to the load in a variety of optional ways.

[0042] The emergency AC input port and the emergency DC input port are selectively connected, that is, the emergency drive device either chooses to be connected to the emergency AC input port or the emergency DC input port, and the two cannot be connected at the same time.

[0043] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0044] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
