[0036] The present utility model discloses a mobile charging vehicle. As Figures 1 - 3 shown, the mobile charging vehicle includes a container body 1, a charging system, and a mounting panel 4. The container body 1 is provided with a movable sealing door 101b. An energy storage system 2 is provided inside the container body 1. The charging system is arranged inside the container body 1 and is electrically connected to the energy storage system 2. The charging system includes a charging terminal 301 and a charging gun 302 connected to the charging terminal 301. Among them: when the container body 1 is being transported, the sealing door 101b is in a closed state and can block the charging gun 302; when the container body 1 is stationary, the sealing door 101b is in an open state, and the charging gun 302 is exposed to enable the charging gun 302 to charge the electrical equipment. It can be understood that during the transportation process, the sealing door 101b is in a closed state. On the one hand, it can well hide the charging gun 302 behind the sealing door 101b, which can better protect the charging gun 302 and avoid the phenomenon of the charging gun 302 being damaged, thereby prolonging the service life of the charging gun 302. When the sealing door 101b is in an open state, the charging gun 302 can be exposed to directly charge the electrical equipment, meeting the charging needs in both the transportation and stationary states. At the same time, since both the charging system and the energy storage system 2 are integrated inside the container body 1, during the actual working process, different vehicle bodies 20 can be replaced according to actual needs, so that the mobile charging vehicle can meet the charging needs in different environments, thereby expanding the applicable range of the mobile charging vehicle.

[0037] Referring to Figures 1 - 3 shown, the sealing door 101b is provided on the left side wall and / or the right side wall of the container body 1. It should be added that in some embodiments, the sealing door 101b is provided on the left side wall of the container body 1. Correspondingly, the mounting panel 4 is arranged at a position on the left side inside the container body 1; in some embodiments, the sealing door 101b is provided on the right side wall of the container body 1. Correspondingly, the mounting panel 4 is arranged at a position on the right side inside the container body 1; in some embodiments, the sealing door 101b is provided on both the left side wall and the right side wall of the container body 1. Correspondingly, the mounting panel 4 is arranged at positions on both the left and right sides inside the container body 1. In addition, the number and specific form of the energy storage system 2 can be selected according to actual needs, and the specific structure, number, and arrangement of the energy storage system 2 are not limited herein.

[0038] Referring to Figures 1 - 3As shown in the figure, the side wall of the container body 1 includes an upper part 101a and a lower part. The lower part forms a rotatable closing door 101b, and the rotating shaft 1013 of the closing door 101b is arranged at the bottom of the container body 1. When the closing door 101b is in the closed state, the side away from the rotating shaft 1013 of the closing door 101b abuts against the upper part 101a to form the side wall of the container body 1. When the closing door 101b rotates downward around the rotating shaft 1013, the closing door 101b can move from the closed state to the open state. It can be understood that by arranging the closing door in the lower part, the planar space of the side wall of the container body 1 can be fully utilized, improving the space utilization rate. In addition, by arranging the closing door 101b in the lower part of the container body 1 and arranging the rotating shaft 1013 of the closing door 101b at the bottom of the container body 1, when the closing door 101b rotates downward around its rotating shaft 1013, the closing door 101b can move from the closed state to the open state. The structure of downward flipping and closing is more convenient for users to open and close the closing door 101b. And when in the open state, the closing door 101b is in a hanging state without the need for an additional support mechanism for support.

[0039] Optionally, a display screen 11 is provided on the upper part 101a of the side wall of the container body 1. The display screen 11 can play advertisements or other videos, which can achieve additional income. And the display screen 11 is arranged on the upper part 101a of the side wall of the container.

[0040] Reference Figure 4 As shown in the figure, a plug-in part 102 is provided on the frame of the container body 1. A plug-in slot is provided on the plug-in part 102, and a plug block 1011 that can be inserted into the plug-in slot is provided on the closing door 101b. Plug holes are provided on both the plug-in part 102 and the plug block 1011, and a plug pin 103 is inserted into the plug holes. The plug pin 103 is used to fix the plug-in part 102 and the plug block 1011. It can be understood that during the actual working process, when it is necessary to open the closing door 101b, only the plug pin 103 needs to be pulled out and the closing door 101b can be rotated. When it is necessary to close the closing door 101b after charging is completed, only the closing door 101b needs to be rotated to make the plug block 1011 inserted into the plug-in slot, and then the plug pin 103 is inserted. Thus, it is convenient to open and close the closing door 101b.

[0041] It should be supplemented and explained that in the alternative embodiment of the present invention, the closing door 101b can be designed as a movable door that moves along the height direction of the container body 1, or can also be set as a movable door that moves along the length direction of the container body 1. That is to say, in the present invention, the form of the closing door 101b can be various, not limited to the technical solution of the above-mentioned rotating door.

[0042] Reference Figure 5As shown in the figure, a partition 6 is provided inside the mobile charging vehicle to divide the container body 1 into multiple installation spaces, and each installation space can be used to install an auxiliary system. The auxiliary systems include a fire protection system, a power distribution system, an off-grid and grid-connected system 9, and a cooling system 10. It can be understood that installing multiple auxiliary systems in multiple installation spaces separately to isolate them from each other will not affect each other, enabling each auxiliary system to have good heat dissipation conditions, so as not to affect its use, and making the center of gravity of the entire mobile charging vehicle centered, improving its stability. It should be added here that the layout of the partition 6 can be arranged according to the quantity and volume of the auxiliary systems. The quantity of the partition 6 and the specific division of the multiple installation spaces are not limited here, and the size and layout of the installation spaces can be selected according to actual needs.

[0043] Reference Figure 1 and Figure 5 As shown in the figure, the fire protection system includes a fire cabinet 701 and a fire exhaust fan 702 provided in the installation space. A fire switching control box 104, a fire water injection port 105, and a fire control host 106 are also provided on the container body 1. It can be understood that the fire protection system is used for safety protection when a fire breaks out in the container, and uses two modes of extinguishing with fire-fighting media and water injection for double protection, improving the working safety of the energy storage container. Users can operate the fire control host 106 and the fire switching control box 104 to switch the fire protection mode according to actual needs. The fire control host 106, the fire cabinet 701, the fire exhaust fan 702, and the fire switching control box 104 can all be obtained according to the existing technology, and there is no need to describe their specific structures in detail here. Further, a fire pressure relief window 1012 can also be provided on the top of the container body 1. Thus, when a thermal runaway occurs in the mobile charging vehicle, the pressure can be relieved in time to avoid explosion.

[0044] In some optional embodiments, the power distribution system is electrically connected to the charging system and the energy storage system 2. The power distribution system includes an independently provided AC power distribution cabinet 801 and a DC power distribution cabinet 802. It can be understood that the power of each system inside the mobile charging vehicle is distributed by connecting cables, and the AC and DC are arranged separately to reduce the interference between them, improve the system stability, and reduce the volume of a single cabinet, so that it can be installed in a narrow space and improve the space utilization rate. It should be added here that the specific structures and control logics of the AC power distribution cabinet 801 and the DC power distribution cabinet 802 can be obtained according to the existing technology, and there is no need to describe the internal structures of the AC power distribution cabinet 801 and the DC power distribution cabinet 802 in detail here.

[0045] Reference Figure 5As shown in the figure, the charging system includes multiple charging terminals 301. The charging system further includes a charging host 304 connected to the multiple charging terminals 301. The charging host 304 is electrically connected to the energy storage system 2. It can be understood that the charging host 304 is connected to the charging terminals 301 through cables, converts the electric energy from the power grid or the energy storage system 2 into electric energy available for charging electric vehicles, etc., and transmits it to the charging terminals 301, and can provide a charging power of up to 630 KW for the charging terminals 301. The charging terminals 301 are connected to the charging guns 302 through charging lines 303, and internally integrate switches and control programs to control whether to transmit the electric energy from the charging host 304 to the charging guns 302, so as to provide charging services for vehicles externally. Further, a charging host exhaust port 1010 corresponding to the charging host 304 is also provided on the container body 1, thereby enabling better heat dissipation of the charging host 304 and avoiding the occurrence of overheating of the charging host 304.

[0046] Reference Figure 5 As shown in the figure, the off-grid and grid-connected system 9 is used for AC-DC conversion of the electric energy in the commercial power and the energy storage system 2. It can be understood that the off-grid and grid-connected system 9 internally integrates a high-power AC-DC bidirectional inverter to perform AC-DC conversion on the electric energy in the commercial power and the energy storage system 2. When grid-connected, it can provide electric energy to the commercial power grid or charge the energy storage system 2 through the commercial power grid. When off-grid, it converts the electric energy in the energy storage system 2 into the electric energy required by each system in the mobile charging vehicle. Further, a first air inlet 108 and a first air outlet 109 corresponding to the off-grid and grid-connected system 9 are also provided on the container body 1. Thus, it can better achieve heat dissipation of the off-grid and grid-connected system 9 and avoid the occurrence of overheating of the off-grid and grid-connected system 9.

[0047] Reference Figure 5 As shown in the figure, the cooling system 10 is used to cool the charging system and the energy storage system 2. It can be understood that the cooling system 10 is composed of a liquid chiller, liquid cooling pipelines, and a liquid cooling medium. The liquid cooling pipelines connect the liquid chiller to the energy storage system 2 and the charging system, and adjust the temperature of the liquid cooling medium through the liquid chiller to heat or cool the energy storage system 2 and the charging system, so that the temperatures of the energy storage system 2 and the charging system are maintained in the optimal working state, ensuring the working safety of the mobile charging vehicle. Further, a liquid cooling host air inlet 107 corresponding to the liquid chiller is also provided on the container body 1, which is beneficial to the timely dissipation of the heat of the liquid cooling host, thereby ensuring the cooling effect of the cooling system 10 on the charging system and the energy storage system 2. Of course, in other embodiments of the present invention, the cooling system 10 can also have multiple cooling fans, and the multiple cooling fans are correspondingly arranged with the energy storage system 2 and the charging system. That is to say, in the embodiments of the present invention, the cooling form of the cooling system 10 can be selected according to actual needs and is not limited to the aforementioned liquid cooling method.

[0048] Further, referenceFigure 5 As shown, the energy storage system 2 is located in the middle of the mobile charging vehicle. Multiple charging piles of the charging system are located on the left and right sides of the energy storage system 2. The liquid cooling cabinet of the cooling system 10, the fire protection cabinet 701 of the fire protection system, and the off-grid and grid-connected system 9 are located on the front side of the energy storage system 2. And the fire protection cabinet 701 is in the middle, and the liquid cooling cabinet and the off-grid and grid-connected system 9 are on both sides. The charging host 304 of the charging system is located on the rear side of the energy storage system 2. The AC power distribution cabinet 801 and the charging terminal 301 are arranged in parallel and are located on the left side of the energy storage system 2. The DC power distribution cabinet 802 is located on the left side of the charging host 304. It can be understood that the energy storage system 2 is located in the middle of the mobile charging vehicle, making the center of gravity of the entire mobile charging vehicle located at the central position, improving the stability and safety during the moving process.

[0049] Optionally, the mobile charging vehicle further includes a photovoltaic module installed on the top of the container body 1. The photovoltaic module is used to supply electric energy to the charging system and the energy storage system 2. It can be understood that by arranging the photovoltaic module on the top of the container body 1, installing a photovoltaic cabinet inside the container body 1, and integrating a photovoltaic inverter in the photovoltaic cabinet; connecting the photovoltaic panel and the photovoltaic cabinet with a cable to form a microgrid; connecting the photovoltaic cabinet with the off-grid and grid-connected system 9 and the charging host 304 with cables respectively to charge the energy storage system 2 or supply power to the charging gun 302 through the charging host 304 to provide charging services for vehicles and the like.

[0050] Reference Figure 3 and Figure 6 As shown, the mobile charging vehicle further includes a mounting panel 4. The mounting panel 4 is installed inside the container body 1 and is used to support the charging gun 302. In the closed state, the sealing door 101b can block the mounting panel 4, and in the open state, the sealing door 101b can expose the mounting panel 4. It can be understood that by supporting the charging gun 302 through the mounting panel 4, the stability of the charging gun 302 can be improved, and the phenomenon of the charging gun 302 falling during the movement of the mobile charging vehicle can be avoided.

[0051] Reference Figure 3 and Figure 6As shown in the figure, the mobile charging vehicle further includes a sealing plate 12. The sealing plate 12 is arranged inside the container body 1, and the sealing plate 12 is used to separate the charging terminal 301 and the sealing door 101b. An installation opening 1201 is provided on the sealing plate 12, and the installation panel 4 is rotatably installed in the installation opening 1201 to close or open the installation opening 1201. A wire trough 401 and a charging seat 5 are provided on the installation panel 4. The charging seat 5 is used to support the charging gun 302. One end of the charging wire 303 of the charging gun 302 is connected to the charging terminal 301, and the other end can be clamped into the wire trough 401. It can be understood that the charging pile is arranged inside the sealing plate 12, an installation opening 1201 is provided on the sealing plate 12, and the installation panel 4 is arranged on the sealing plate 12 in an openable and closable manner. When not in use, the charging gun 302 is blocked inside the sealing plate 12. When the charging gun 302 needs to be taken out, only the installation panel 4 needs to be opened, so that the charging wire 303 is stuck in the wire trough 401, and then the charging gun 302 is taken out from the installation opening 1201 and placed on the charging seat 5, and the installation panel 4 is closed. Thus, during transportation, the charging gun 302 can be placed inside the sealing plate 12 for storage and protection, and during use, only the installation panel 4 needs to be opened to conveniently take out the charging gun 302 for use.

[0052] Reference Figure 6 As shown in the figure, a door lock 13 is provided on the installation panel 4. It can be understood that by setting the door lock 13 on the installation panel 4, a key is required to open the door lock 13 during the working process to take out the charging gun 302, which avoids the phenomenon that unauthorized personnel take out the charging gun 302, improves safety, and avoids the phenomenon that the charging gun 302 is lost or internal devices such as the charging pile are damaged. It should be noted here that the structure of the door lock 13 is a prior art, and the structure of the door lock 13 does not need to be specifically limited here.

[0053] Reference Figures 6 - 7 As shown in the figure, a wire clamping block 14 is further provided on the installation panel 4. The wire clamping block 14 is detachably installed in the wire trough 401, and the wire clamping block 14 has a clamping hole 1401 for clamping the charging wire 303. It can be understood that according to the previous text, during the process of taking out the charging gun 302, the charging wire 303 needs to pass through the wire trough 401. If the charging wire 303 is prone to shaking relative to the wire trough 401, then when the user holds the charging gun 302, the end of the charging wire 303 connected to the charging pile is likely to be affected, resulting in poor contact. In this embodiment, clamping the charging wire 303 in the wire trough 401 through the wire clamping block 14 can fix the charging wire 303, avoid the charging wire 303 from shaking in the wire trough 401, ensure that the charging wire 303 is firmly connected to the charging pile when the user holds the charging gun 302, and thus ensure the charging reliability and safety.

[0054] Further, the card hole 1401 includes a tapered section and a straight hole section. The small end of the tapered section is connected to the straight hole section, and the diameter of the straight hole section is equal to the diameter of the charging wire 303. Of course, in other embodiments of the present invention, the card hole 1401 may also be directly formed as a straight hole with a diameter equal to that of the charging wire 303.

[0055] Refer to Figures 6 - 7 As shown, the wire clamping block 14 is provided with a slot 1403. The wire clamping block 14 can be inserted into the wire passing groove 401 from the notch of the wire passing groove 401 so that the slot 1403 is inserted into the wall surface of the mounting panel 4 where the wire passing groove 401 is provided. It can be understood that during the actual installation process, the wire clamping block 14 is first installed on the charging wire 303, and then the wire clamping block 14 is inserted from the notch of the wire passing groove 401 so that the slot 1403 is inserted into the wall surface of the mounting panel 4 where the wire passing groove 401 is provided. Thus, when fixing the wire clamping block 14, no connecting parts such as screws are required, which simplifies the operation of installing the wire clamping block 14 and thus facilitates the user to fix the wire clamping block 14.

[0056] The wire clamping block 14 includes at least two sub-blocks 1402. Each sub-block 1402 is provided with a wire clamping groove. The at least two sub-blocks 1402 are sequentially spliced to form the wire clamping block 14 so that a plurality of wire clamping grooves are spliced into the card hole 1401. It can be understood that if the wire clamping block 14 is an integral structure, a notch needs to be provided on the card hole 1401 for clamping the charging wire 303. In this way, during the installation process, the charging wire 303 needs to be pressed into the card hole 1401 from the notch, which is likely to cause wear of the charging wire 303 over a long time and may even lead to a leakage phenomenon. In this embodiment, the wire clamping block 14 includes a plurality of sub-blocks 1402, and the plurality of sub-blocks 1402 are sequentially spliced to form the wire clamping block 14 so that a plurality of wire clamping grooves are spliced into the card hole 1401. In this way, the entire card hole 1401 can be a complete round hole. On the one hand, it can improve the clamping effect on the charging wire 303. On the other hand, during the installation process, the charging wire 303 will not have hard contact with the wire clamping block 14, avoiding wear of the charging wire 303 and ensuring charging reliability.

[0057] Optionally, the two sub-blocks 1402 are attracted and combined by a magnetic attraction structure. Thus, when the two sub-blocks 1402 are installed on the charging cable 303, the magnetic attraction structure between the two sub-blocks 1402 can ensure stability and avoid the jamming phenomenon caused by the separation of the sub-blocks 1402 when the entire cable clamping block 14 is inserted into the wire slot 401. In an alternative embodiment, each sub-block 1402 is provided with a splicing slot and / or a splicing protrusion. Among two adjacent sub-blocks 1402, the splicing protrusion on one sub-block 1402 can cooperate with the splicing slot of the other sub-block 1402. Thus, when the two sub-blocks 1402 are installed on the charging cable 303, the clamping connection between the splicing slot and the splicing protrusion of the two sub-blocks 1402 can ensure stability and avoid the jamming phenomenon caused by the separation of the sub-blocks 1402 when the entire cable clamping block 14 is inserted into the wire slot 401. Of course, in other embodiments of the present invention, the connection structure between the two sub-blocks 1402 can also be selected according to actual needs, and is not limited to the above description.

[0058] Reference Figure 7 As shown, the mounting panel 4 is provided with a mating port 402, and the charging base 5 is installed in the mating port 402 so that the surface of the charging base 5 is flush with the surface of the mounting panel 4. It can be understood that installing the charging base 5 in the mating port 402 of the mounting panel 4 so that the surface of the charging base 5 is flush with the surface of the mounting panel 4 can prevent the charging base 5 from protruding from the sealing plate 12 and improve the aesthetics of the mounting panel 4.

[0059] Furthermore, the mounting panel 4 has a fixed convex edge 403 that surrounds the mating port 402 and faces the sealing plate 12, and the charging base 5 is fixed to the fixed convex edge 403 by a connecting member. It can be understood that during actual installation, the charging base 5 is inserted from the front of the mounting panel 4 and cooperates with the mating port 402. After the mounting surface of the charging base 5 abuts against the fixed convex edge 403, a connecting member is used to fix the charging base 5 to the fixed convex edge 403 from the rear side of the mounting panel 4, thus facilitating the installation of the charging base 5. In the embodiment of the present invention, the connecting member can be a screw or a pin. Of course, in other embodiments of the present invention, the charging base 5 can be directly adhered to the fixed convex edge 403, or the charging base 5 is fixed to the fixed convex edge 403 through a snap structure.

[0060] It should be noted that the process of removing and temporarily storing the charging gun 302 is introduced below:

[0061] When in use, take out the multiple bolts 103 inserted into the closing door 101b, rotate the closing door 101b to move it from the closed state to the open state, then use the key to open the door lock 13, open the installation panel 4, take out the charging gun 302, after taking out the charging gun 302, insert the charging gun 302 into the charging socket 5 on the installation panel 4, then slide the wire clamping block 14 out of the notch of the wire trough 401, separate the wire clamping block 14, and clamp the charging cable 303 with two sub-blocks 1402, and then slide the combined wire clamping block 14 into the installation panel 4 from the notch of the wire trough 401, so that the slot 1403 on the wire clamping block 14 is inserted into the wall surface of the wire trough 401 provided on the installation panel 4, then close the installation panel 4 and lock the door lock 13. At this time, the user can conveniently use the charging gun 302 to charge.

[0062] When it is necessary to retract the charging gun 302, open the door lock 13, open the installation panel 4, slide out the wire clamping block 14, remove the wire clamping block 14 from the charging cable 303, then install the wire clamping block 14 back on the installation panel 4, unplug the charging gun 302, and then put the charging gun 302 and the charging cable 303 into the installation panel 4; close the installation panel 4, lock the door lock 13, and finally rotate the closing door 101b to move it from the open state to the closed state, and insert the bolt 103 back to complete the storage.
