DETAILED DESCRIPTION

[0030] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0031] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details that hinder the description of the present invention.

[0032] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0033] It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more centered elements can exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more centered elements can exist between them. When the terms "vertical", "horizontal", "left", "right", "up", "down", "inside", "outside", "bottom", etc. are used to indicate an orientation or positional relationship, it is based on the orientation or positional relationship shown in the accompanying drawings, only for the convenience of description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0035] like Figure 1 and Figure 2As shown, the charging port and the discharging port of the mobile storage and charging machine in the related art are separated. When the mobile storage and charging machine is storing energy, it is necessary to use the charging gun on the charging pile 2 to charge the storage and charging machine to complete the energy storage. When the mobile storage and charging machine is in the charging state of self-energy storage, the charging gun on the charging pile 2 is inserted into the charging socket 101 of the mobile storage and charging machine. Under the control of the controller 107, the electric energy signal is output from the charging pile 2 and flows through the second DC contactor group 102 to reach the rechargeable power supply 103, thereby completing the energy storage of the rechargeable power supply 103. When the mobile storage and charging machine charges the device to be charged, such as the electric car 3 (self-discharge), the charging gun 106 of the mobile storage and charging machine is inserted into the charging inlet of the device to be charged, and the electric energy signal flows from the rechargeable power supply 103 through the DC bidirectional module 104 and the first DC contactor group 105, and is transmitted to the device to be charged through the charging gun 106, thereby completing the charging of the device to be charged.

[0036] However, since the charging circuit and the discharging circuit are two separate circuits, the charging and discharging ports are also independent, which leads to low material utilization. The mobile storage and charging integrated machine produced will have the disadvantages of heavy weight, bulky volume, and inflexible movement. Therefore, a mobile DC bidirectional storage and charging integrated machine is proposed.

[0037] In a preferred embodiment, reference Figure 3 A mobile DC bidirectional charging and storage device of this embodiment includes a housing 10, a DC bidirectional charging and discharging circuit 100 disposed in the housing 10, and a charging gun 106 electrically connected to the DC bidirectional charging and discharging circuit 100. The charging gun 106 is connected to the DC bidirectional charging and discharging circuit 100 through a wired cable.

[0038] When the DC bidirectional charging and discharging circuit 100 receives a discharge signal, a discharge path is formed between the DC bidirectional charging and discharging circuit 100 and the charging gun 106, so that the storage-charging integrated device supplies power to the device to be charged through the discharge path.

[0039] When the DC bidirectional charging and discharging circuit 100 receives a charging signal, a charging path is formed between the DC bidirectional charging and discharging circuit 100 and the charging gun 106 , so that the storage-charging integrated device stores energy through the charging path.

[0040] It should be noted that the discharge signal and the charge signal in this embodiment can be corresponding high and low level signals, or other forms of signals. The signal flow directions in the discharge path and the charge path are two opposite electric energy signal flow directions.

[0041] In this embodiment, by combining the charging circuit and the discharging circuit into one, a charging gun 106 is shared during charging and discharging, thereby improving the material utilization rate in the equipment, effectively reducing the material cost, further optimizing the product structure and weight, and improving the product's mobility.

[0042] Optionally, the mobile storage-charging machine of this embodiment may be provided with at least three rollers 14 below the housing 10 for easy movement. Of course, in order to improve stability, the number of rollers 14 may be increased, such as 4, 6, etc. The specific number is not limited, and the number of rollers 14 may be changed according to the actual volume size of the mobile storage-charging machine required by the user.

[0043] In a specific alternative embodiment, Figure 4 As shown, the DC bidirectional charging and discharging circuit 100 includes a rechargeable power source 103 and a DC bidirectional module 104 for forming a discharge path or a charging path through bidirectional energy conversion. The rechargeable power source 103 is electrically connected to the DC bidirectional module 104, and the DC bidirectional module 104 is electrically connected to a charging gun 106. The specific circuit structure of the DC bidirectional module 104 can refer to the prior art and will not be repeated here.

[0044] Based on the above embodiments, reference Figure 5 The DC bidirectional charging and discharging circuit 100 further includes a second DC contactor group 102 connected between the DC bidirectional module 104 and the charging gun 106 .

[0045] When the second DC contactor group 102 receives a discharge signal or a charge signal, a discharge path or a charge path is correspondingly formed between the DC bidirectional module 104 and the charging gun 106 .

[0046] Specifically, Figure 6 As shown, the second DC contactor group 102 includes a first contactor 1K1 and a second contactor 1K2. The two ends of the contact of the first contactor 1K1 are respectively connected to the negative pole of the DC bidirectional module 104 and the negative pole of the charging gun 106, and the two ends of the contact of the second contactor 1K2 are respectively connected to the positive pole of the DC bidirectional module 104 and the positive pole of the charging gun 106.

[0047] In the mobile DC bidirectional charging and storage device of some embodiments, the DC bidirectional charging and discharging circuit 100 further includes a controller 107 electrically connected to the second DC contactor group 102 .

[0048] When the controller 107 receives a discharge instruction input by the user, it sends a corresponding discharge signal to the second DC contactor group 102 , so that a discharge path is formed between the DC bidirectional module 104 and the charging gun 106 .

[0049] When the controller 107 receives a charging instruction input by the user, it sends a corresponding charging signal to the second DC contactor group 102 , so that a charging path is formed between the DC bidirectional module 104 and the charging gun 106 .

[0050] It should be noted that the controller 107 is mainly used to generate a corresponding discharge signal or a charge signal to trigger the corresponding circuit between the DC bidirectional charge and discharge circuit 100 and the charging gun 106 to be turned on.

[0051] It can be understood that in this embodiment, the design of the charging circuit and the discharging circuit sharing a main circuit (DC bidirectional charging and discharging circuit 100) increases the utilization efficiency of electrical devices, effectively reduces production costs, optimizes the structure to a certain extent, reduces the volume, and makes movement more convenient.

[0052] Optionally, the mobile DC bidirectional storage and charging integrated machine of this embodiment also includes a user input module disposed on the housing 10, electrically connected to the controller 107, and used to generate a discharge instruction or a charge instruction. Exemplarily, the user input module includes but is not limited to a touch screen, a key unit, a handwriting board, and the like. Of course, a display screen 13 can also be provided on the integrated machine, and a keyboard or key can be combined to provide a user input entrance. Or a touch screen can be directly provided. A group of keys can also be provided, such as a charging key and a discharging key. After the DC bidirectional charging and discharging circuit 100 receives the signal triggered by the corresponding key, the corresponding charging and discharging path is opened.

[0053] Optionally, the mobile DC bidirectional charging and storage device of this embodiment further includes an indicator light 12 disposed on the housing 10, connected to the DC bidirectional charging and discharging circuit 100, and used to indicate a charging state or a discharging state.

[0054] As an option, a communication cable may be provided between the DC bidirectional charge and discharge circuit 100 and the charging gun 106. The communication cable is used for charging matching between the DC bidirectional charge and discharge circuit 100 and the device to be charged, or for charging matching between the DC bidirectional charge and discharge circuit 100 and the charging pile 2.

[0055] Combination Figure 6 The working principle of the present invention is described below through the charging process and the discharging process of the mobile DC bidirectional storage-charging device of this embodiment.

[0056] When the charging pile 2 is needed to charge the mobile storage and charging machine, first insert the charging gun 106 into the charging pile 2, click the "Mobile storage and charging machine charging" virtual button through the display screen 13, and trigger the charging instruction to the controller 107. At this time, the mobile storage and charging machine and the charging pile 2 are charged and matched through the first communication line 111 (communication cable). After completing the relevant charging data matching, the controller 107 generates a corresponding charging signal to turn on the second DC bidirectional contactor group, so that the DC bidirectional charging and discharging circuit 100 and the charging gun 106 form a charging path, and the electric energy signal is charged through the path of the charging path (charging pile 2→charging gun 106→first DC contactor group 105→DC bidirectional module 104→rechargeable power supply 103), thereby completing the charging and energy storage of the mobile storage and charging machine.

[0057] When the mobile storage and charging machine is needed to charge the electric car 3 (discharging state), first insert the charging gun 106 into the electric car 3, click the virtual button of "Charging Electric Car 3" through the display screen 13, and trigger the discharge instruction to the controller 107. At this time, the mobile storage and charging machine and the electric car 3 are charged and matched through the first communication line 111. After completing the matching of relevant charging data, the controller 107 generates a corresponding discharge signal to turn on the second DC bidirectional contactor group, so that the DC bidirectional charging and discharging circuit 100 and the charging gun 106 form a discharge path, and the electric energy signal is discharged through the path of the discharge path (rechargeable power supply 103→DC bidirectional module 104→first DC contactor group 105→charging gun 106→electric car 3), thereby completing the charging of the electric car 3 by the mobile storage and charging machine.

[0058] The utility model combines the charging circuit and the discharging circuit into one, and shares a charging gun 106 during charging and discharging, thereby improving the material utilization rate in the equipment, effectively reducing the material cost, further optimizing the product structure and weight, and improving the mobility of the product.

[0059] In another preferred embodiment, the mobile DC bidirectional storage and charging system of this embodiment includes the mobile storage and charging integrated machine and the charging pile 2 as described above. The storage and charging integrated machine is connected to the charging pile 2 through a charging gun 106, and the charging pile 2 stores energy for the storage and charging integrated machine through a charging path.

[0060] The utility model combines the charging circuit and the discharging circuit into one, and shares a charging gun 106 during charging and discharging, thereby improving the material utilization rate in the equipment, effectively reducing the material cost, further optimizing the product structure and weight, and improving the mobility of the product.

[0061] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model.
