[0039] For a thorough understanding of the present application, reference will be made to the following detailed description taken in conjunction with the accompanying drawings, in which:

[0040] Referring to Figures 1-4 As shown in the drawings, the present application discloses a movable energy storage charging device, which is not limited by itself, small in size and convenient for users to carry, and realizes timely charging of a vehicle body.

[0041] The movable energy storage charging device comprises a chassis assembly 1, a battery assembly 2, a control assembly 3, an electrical box 4, a fire-fighting assembly 5 and a distribution box 22. The chassis assembly 1 comprises a support 11 and a shell 12 connected to the support 11, and a containing space is formed between the support 11 and the shell 12. The shell 12 can be opened or closed relative to the support 11 to adapt to the working state and non-working state of the charging device. The battery assembly 2, the control assembly 3, the distribution box 22, the electrical box 4 and the fire-fighting assembly 5 are all arranged in the containing space to protect the charging device in the non-working state from being collided or having dust entering the containing space; the battery assembly 2 comprises a battery pack arranged in the containing space and a distribution box 22 connected to the battery pack, the battery pack is located at the front of the device, the battery pack is used for storing electric energy, and an inverter 6 is used for converting direct current stored by the battery pack into alternating current for output; the distribution box 22 is arranged in the containing space, and the distribution box 22 is connected to the battery assembly 2 to control the flow direction of high-voltage electricity according to the working state and needs of the device. When the battery assembly 2 of the device needs to be charged, the distribution box 22 guides the electric energy of an external power supply to the battery assembly 2 for charging; when other electric vehicles are charged, the electric energy of the battery assembly 2 is distributed to the corresponding load; and the electrical box 4 is arranged in the containing space and connected to the control assembly.

[0042] It should be noted that in the embodiment, a charging port 221 and an electricity outlet 222 are further arranged at the rear of the distribution box 22, the charging port 221 is used for connecting with an external power supply to store electric energy, and the electricity outlet 222 is used for connecting with a load to be charged to supply power to the load to be charged.

[0043] In the embodiment, the height of the distribution box 22 is lower than that of the battery pack, and the inverter 6, the control assembly 3, the electrical box 4 and the fire-fighting assembly 5 are all located above the distribution box 22. In this way, on the one hand, the containing space can be reasonably arranged, and the battery pack is arranged in front of the distribution box 22, so that the center of gravity of the entire charging device is closer to the front due to the weight of the battery pack being greater than that of the distribution box 22, thereby improving the stability and safety of the charging device during movement and charging; on the other hand, this layout helps to optimize the connection structure of each component, so that the connection between each component is more compact, reduces the energy transmission loss, and at the same time reduces the volume of the entire charging device, which is convenient for users to carry, thereby solving the problem of anchoring caused by insufficient electric energy or power system failure of the vehicle body.

[0044] In the embodiment, the chassis assembly 1 further comprises a rack body 13 connected with the support 11, and a limiting part 131 is arranged on the rack body 13, which is used to abut against the shell 12 to prevent the shell 12 and the components in the accommodating space from moving, improve the stability, and prevent the shell 12 and the components in the accommodating space from being collided by other heavy objects. In the embodiment, the support 11 is triangular, and the triangular support 11 has high stability and strength, which ensures the safety and reliability of the device.

[0045] In one of the embodiments, the battery pack comprises three battery components 21 arranged on the chassis assembly 1 from top to bottom. The arrangement of the three battery components 21 from top to bottom can reduce the occupied space, and on the other hand, can improve the performance of the entire charging device, for example, can provide larger energy storage capacity, meet longer charging demand or provide charging service for more devices, by connecting multiple battery components 21 in parallel, the total output current can be increased, the output power of the device can be improved, so that the target vehicle body can be charged faster, when one of the battery components 21 fails, the other battery components 21 can still work, and the entire charging device will not be completely disabled, which improves the reliability of the system, and multiple batteries can also share the load, reduce the pressure of a single battery, and prolong the service life of the battery.

[0046] As described above, the fire-fighting assembly 5 is also arranged in the accommodating space, specifically above the distribution box 22, which further improves the compactness of the entire device. The fire-fighting assembly 5 comprises a fire extinguishing device detachably connected with the chassis assembly 1, a detection device connected with the control assembly, and an alarm. The charging device further comprises a mounting support 11 having a positioning groove, and the fire extinguishing device is detachably mounted in the positioning groove to prevent the fire extinguishing device from shaking, being damaged or causing personal injury when the charging device is moved. The fire extinguishing device can be a dry powder extinguisher, a carbon dioxide extinguisher, a foam extinguisher, a clean gas extinguisher, etc., and the type of the fire extinguishing device can be selected and installed according to the demand.

[0047] In the embodiment, the detection device is a smoke detector and / or a temperature detector to detect the environment around the charging device. If the detection device detects that the value of the environment is different from the preset safety value, the detection signal is transmitted to the control assembly, and the control assembly controls the alarm to alarm, so that the operator can quickly take out the fire extinguishing device for processing, to avoid unnecessary property loss and personal injury.

Specifically, the liquid cooling heat dissipation assembly 9 comprises a liquid storage tank, a pump body connected to the liquid storage tank, and a pipeline in communication with the liquid storage tank, the pipeline being distributed between each two adjacent battery components 21, the liquid storage tank being used to store cooling liquid, and the pump body being used to circulate the cooling liquid in the pipeline. In this embodiment, a plurality of pipelines are provided, each extending into the space between the three battery components 21, so that heat exchange can be achieved more efficiently. It is worth noting that, in this embodiment, compared with the fan heat dissipation, the liquid cooling heat dissipation assembly 9 is used to dissipate heat from the battery pack, and the specific heat capacity of liquid is larger, which can absorb more heat, so that the temperature of the device can be reduced more effectively. Liquid cooling heat dissipation can more evenly conduct heat away from the heat generating components, avoiding the generation of local hot spots, making the temperature of the device more uniform, which helps to improve the stability and reliability of the device.

[0049] The device further comprises a monitoring assembly 7 connected to the control assembly, the monitoring assembly 7 also being located above the distribution box 22, further improving the compactness of the device, the monitoring assembly 7 being adapted to detect the performance of the battery assembly 2 and transmit the performance of the battery assembly 2 to the control assembly for reference by the operator. In this embodiment, the performance that can be monitored by the monitoring assembly 7 includes the voltage, current, temperature, remaining capacity and health status of the battery pack, etc., so as to prevent overcharging, overdischarging, overcurrent and overheating of the battery pack, thereby ensuring the safe, reliable and efficient operation of the battery pack. It should be noted that, in this embodiment, the connection between the monitoring assembly 7 and the control assembly and the information transmission are both relatively mature technologies in the art, and therefore will not be described here.

[0050] In one of the embodiments, the device further comprises a wheel assembly 8 installed below the chassis assembly 1, the wheel assembly 8 comprising front wheels 81 and rear wheels 82, so that the entire charging device is easy to move. In this embodiment, in the front-rear direction of the device, the battery assembly 2 is located in front of the front wheels 81.
