Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a mobile charging pile. Background Technology

[0002] With the increase in the number of electric vehicles, the demand for charging piles has also increased significantly. Fixed charging piles require car owners to find charging stations on their own because the locations are fixed. However, the number of charging piles is limited and the charging time is relatively long. At the same time, there are times when the electric vehicle's battery is insufficient and it is unable to find a charging pile on its own. Mobile charging piles have emerged to solve the problem of temporary charging difficulties.

[0003] Most mobile charging stations on the market currently adopt a traditional box-type structure, which centrally houses the control components, battery packs, and charging / discharging modules within a single enclosed space. This layout has several drawbacks: firstly, the compact arrangement of components leads to inefficient use of internal space, making it difficult to accommodate large-capacity battery packs and limiting the charging station's range; secondly, the batteries and charging / discharging modules are fixedly mounted on corresponding brackets, preventing flexible adjustments to battery capacity and layout according to actual needs. Furthermore, when some components malfunction, overall disassembly and repair are difficult and costly. Therefore, there is an urgent need for a mobile charging station that can optimize space layout, allow for flexible battery configuration, and facilitate maintenance. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model proposes a mobile charging pile to solve the above problems.

[0005] This application proposes a mobile charging pile, including a base, a battery assembly, and a control assembly. The base forms a control compartment and a heat dissipation compartment, which are staggered and divide the top surface of the base into several installation areas. The control assembly is located on top of the control compartment. The battery assembly includes several batteries and several charging / discharging modules, which are stacked sequentially from bottom to top within the installation areas. It also includes air-cooling and water-cooling components for dissipating heat from the battery assembly, arranged vertically within the heat dissipation compartments. This mobile charging pile utilizes the staggered layout of the control and heat dissipation compartments to rationally arrange the installation areas and maximize space utilization. The charging / discharging modules and batteries are stacked in layers within the installation areas. The air-cooling and water-cooling components within the heat dissipation compartments provide heat dissipation for the compactly arranged battery assembly, ensuring the stability of the battery assembly during operation.

[0006] Preferably, the control compartment and heat dissipation compartment are arranged in a cross-shaped pattern, dividing the top surface of the base into four installation areas. From bottom to top, each installation area has several horizontally arranged battery brackets and module brackets for mounting batteries and charging / discharging modules. The module brackets and battery brackets are fixedly or detachably connected to the sides of the control compartment and heat dissipation compartment, respectively. This design ensures structural strength through the fixedly installed module brackets, while the detachable connection of the battery brackets allows for adjustment of the battery bracket distribution according to the battery capacity and size, increasing the battery capacity of the charging pile. The modular layout also facilitates maintenance.

[0007] Preferably, both the control compartment and the heat dissipation compartment are hollow rectangular frames. The control compartment is located above the central axis of the top surface of the base, while the heat dissipation compartments are vertically arranged on both sides of the control compartment. The battery bracket is detachably connected to the control compartment and the heat dissipation compartment via hooks. This design divides the top surface of the base into four evenly spaced installation areas. The charging and discharging modules in each installation area independently control the batteries within that area. The hook installation method facilitates quick assembly and disassembly of the battery bracket and ensures the stability of the batteries during placement. It also facilitates heat dissipation for the charging and discharging modules and batteries through the heat dissipation compartments.

[0008] Preferably, the air-cooled component includes a longitudinally arranged air duct within the heat dissipation chamber, and the upper surface of the heat dissipation chamber, away from the control chamber, has several air inlet windows. This arrangement allows external air to be introduced into the air duct through the air inlet windows, utilizing airflow to dissipate heat from the battery component.

[0009] In a further preferred embodiment, cooling fans are provided on both the front and rear sides of the charging / discharging module, and the heat dissipation chamber has several fan windows corresponding to the fans facing the charging / discharging module. With this configuration, the charging / discharging module can actively dissipate heat, and the cooling fans can also increase the airflow velocity within the air duct, further improving the heat dissipation effect.

[0010] Preferably, the water-cooling assembly includes several water-cooling plates and several water-cooling pipes. The water-cooling plates are attached to the upper surface of the corresponding battery, and one end of each water-cooling pipe is connected to a water-cooling plate, while the other end extends into the heat dissipation chamber. This arrangement improves the battery's heat dissipation effect, as the water-cooling plates attached to the battery surface increase the heat dissipation area, and the water-cooling pipes are concealed within the heat dissipation chamber, optimizing space utilization. More preferably, the surface of the heat dissipation chamber furthest from the control compartment has several recessed pipe connection grooves arranged longitudinally, with the positions of these grooves corresponding to the positions of the batteries. This arrangement gathers the water-cooling pipes from each layer into their corresponding connection grooves, optimizing the spatial layout of the water-cooling pipes.

[0011] In a further preferred embodiment, the water-cooling pipes on both sides penetrate the side wall of the heat dissipation chamber and are connected via pipe joints within the pipe connection groove. This arrangement connects the water-cooling pipes on both sides of the heat dissipation chamber, concealing the weaker connection points of the water-cooling components within the pipe connection groove.

[0012] In a further preferred embodiment, vertically guiding connecting holes are provided between adjacent pipe connection slots. Water-cooled pipes pass through these connecting holes and are connected layer by layer via pipe joints. This arrangement connects the water-cooled pipes of each layer, ensuring that all water-cooled pipes are connected to the same inlet and outlet, forming a complete water-cooled circulation heat dissipation system.

[0013] Preferably, the front of the control compartment is equipped with a charging port, a charging gun insertion port, and a charging gun holder, with a charging gun storage base located below the charging gun holder. This design facilitates charging of the charging station via the charging port, and the charging gun draws power through the insertion port. When not in use, the charging gun's wiring can be wound and stored on the charging gun holder, and the charging gun's nozzle can be inserted into the charging gun storage base for safekeeping.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] The mobile charging pile of this application divides the top surface of the base into four installation areas through a cross-shaped distribution of control compartments and heat dissipation compartments. The layered battery brackets and module brackets ensure structural strength while allowing for flexible expansion of battery capacity through a detachable design. The hollow rectangular frame of the compartment, combined with a hook connection method, enables quick assembly and disassembly and stable heat dissipation while maintaining a lightweight design. The water-cooling and air-cooling composite heat dissipation system and the rationally arranged pipe connection slots significantly improve heat dissipation efficiency and reliability. The integration of functional modules such as charging ports and gun holders, as well as the detachable side cover design, enhances ease of use and maintenance flexibility.

[0025] In the following detailed description, reference is made to the accompanying drawings, which form part of the detailed description and illustrate illustrative specific embodiments in which the present invention may be practiced. In this regard, directional terms such as “top,” “bottom,” “left,” “right,” “up,” “down,” etc., are used with reference to the orientation of the described figures. Because components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present invention. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

[0026] This application proposes a mobile charging station. Figure 1 A three-dimensional structural schematic diagram of a mobile charging station according to an embodiment of this application is shown, as follows. Figure 1 As shown, the charging pile includes a base 01, a battery assembly, and a control assembly. The battery assembly includes several batteries 02 and a charging / discharging module 03. It also includes a control compartment 04 and a heat dissipation compartment 05 that form upwards from the base 01. The control compartment 04 and the heat dissipation compartment 05 are staggered on the base 01, dividing the top surface of the base 01 into several installation areas. The control assembly is placed on top of the control compartment 04. The batteries 02 and the charging / discharging module 03 are stacked sequentially from bottom to top in the installation areas.

[0027] Specifically, the control compartment 04 and the heat dissipation compartment 05 are arranged in a cross pattern, and the top surface of the base 01 is divided into four installation areas. Several battery brackets 06 and module brackets 07 are arranged horizontally from bottom to top in the installation areas. The module brackets 07 and battery brackets 06 are fixedly and detachably connected to the sides of the control compartment 04 and the heat dissipation compartment 05, respectively. The battery 02 and the charging and discharging module 03 are respectively installed on the battery brackets 06 and the module brackets 07.

[0028] In a specific embodiment, an installation area is provided with three charging and discharging modules 03 and six batteries 02. One charging and discharging module 03 connects to and controls two batteries 02. Furthermore, depending on the actual capacity and volume of the batteries 02 used, an installation area may also be provided with only three large-volume, high-capacity batteries 02, which can then form a one-to-one connection with the charging and discharging module 03. In practical applications, the total capacity of the batteries 02 in the four installation areas can reach 180 kWh.

[0029] Specifically, the number of charging / discharging modules 03 / batteries 02 corresponds one-to-one with the number of module brackets 07 / battery brackets 06, and the module brackets 07 are located above the battery brackets 06.

[0030] Furthermore, as a mobile charging pile, casters and a push handle can be added to the base 01 to facilitate the movement of the charging pile. Moreover, since the large-capacity charging pile is heavy, a forklift can be used to transport the mobile charging pile. This application mainly solves the problems of space occupation and battery capacity of existing mobile charging piles, and the moving structure will not be described in detail here.

[0031] Preferably, both the control compartment 04 and the heat dissipation compartment 05 are hollow rectangular frames, with the control compartment 04 located above the central axis of the top surface of the base 01, and the heat dissipation compartment 05 vertically arranged on both sides of the control compartment 04. The control compartment 04 and the heat dissipation compartment 05 divide the top surface of the base 01 into four evenly spaced installation areas. The charging and discharging module 03 in each installation area independently controls the battery 02 in the same installation area, and this also facilitates heat dissipation for the charging and discharging module 03 and the battery 02 through the heat dissipation compartment 05.

[0032] In another specific embodiment, the part of the control compartment 04 corresponding to the battery 02 is hollowed out to facilitate the connection and storage of the battery 02 lines on both sides below the control compartment 04.

[0033] Specifically, the control components include a control circuit board 08 and a module circuit board 09, with the module circuit board 09 equipped with functional modules such as a metering module.

[0034] Figure 2 A partially enlarged view of a battery holder according to a specific embodiment of this application is shown, such as... Figure 1-2As shown, the battery bracket 06 is detachably connected to the control compartment 04 and the heat dissipation compartment 05 via the hook 10. The installation method of the hook 10 facilitates the quick installation and removal of the battery bracket 06 and ensures the stability of the battery 02 when it is placed. In specific applications, the battery bracket 06 can also be fixed to the control compartment 04 and the heat dissipation compartment 05 to further improve stability.

[0035] Figure 3 An enlarged view of the top of the heat sink according to a specific embodiment of this application is shown, as follows: Figure 1-3 As shown, preferably, the air-cooled assembly includes a longitudinally arranged air guide channel 11 within the heat dissipation chamber 05, and the upper surface of the heat dissipation chamber 05 away from the control chamber 04 has several air inlet windows 12. External air is introduced into the air guide channel 11 through the air inlet windows 12, and the airflow is used to dissipate heat from the battery assembly.

[0036] Preferably, the charging / discharging module 03 is equipped with cooling fans 13 on both its front and rear sides, and the heat dissipation chamber 05 has several fan windows 14 corresponding to the fans facing the charging / discharging module 03. With the help of the cooling fans 13 and fan windows 14, the charging / discharging module 03 can actively dissipate heat. The cooling fans 13 can also increase the airflow velocity within the air guide channel 11, further improving the heat dissipation effect.

[0037] Figure 4 A partially enlarged view of the side of the heat sink according to a specific embodiment of this application is shown, such as... Figure 1-4 As shown, the water-cooling assembly includes several water-cooling plates 15 and several water-cooling pipes 16. The water-cooling plates 15 are attached to the upper surface of the corresponding battery 02. One end of the water-cooling pipe 16 is connected to the water-cooling plate 15, and the other end extends into the heat dissipation chamber 05. By further setting water-cooling plates 15 on the battery 02, the heat dissipation effect of the battery 02 is improved. The water-cooling plates 15 are attached to the surface of the battery 02 to increase the heat dissipation area, while the water-cooling pipes 16 are hidden in the heat dissipation chamber 05, optimizing space occupation.

[0038] Further preferably, the surface of the heat dissipation chamber 05 away from the control chamber 04 has several recessed pipe connection grooves 17 arranged longitudinally, and the positions of the pipe connection grooves 17 correspond to the positions of the battery 02. The water-cooling pipes 16 of each layer converge to the corresponding pipe connection grooves 17, thus optimizing the spatial layout of the water-cooling pipes 16.

[0039] More preferably, the water-cooling pipes 16 on both sides penetrate the side wall of the heat dissipation chamber 05 and are connected in the pipe connection groove 17 via pipe joints (not shown in the figure). With this arrangement, the water-cooling pipes 16 on both sides of the heat dissipation chamber 05 are connected, and the weaker connection points of the water-cooling components are hidden in the pipe connection groove 17.

[0040] Furthermore, a vertical guide connecting hole 18 is provided between adjacent pipe connection slots 17. The water-cooled pipes 16 pass through the connecting hole 18 and are connected layer by layer through pipe joints. By connecting the water-cooled pipes 16 of each layer through the connecting hole 18, all water-cooled pipes 16 are connected to the same inlet and outlet, forming a complete water-cooled circulation heat dissipation system. This, together with the air guide channel 11, minimizes the overheating of the charging pile during operation.

[0041] Figure 5 A front view of a mobile charging station according to a specific embodiment of this application is shown, such as... Figure 1-5 As shown, the front of the control compartment 04 is equipped with a charging port 19, a charging gun insertion port 20, and a charging gun holder 21. Below the charging gun holder 21 is a charging gun storage base 22. The charging pile is charged through the charging port 19, and the charging gun draws power through the charging gun insertion port 20. When not in use, the charging gun's wiring can be wound and stored on the charging gun holder 21, and the charging gun head can be inserted into the charging gun storage base 22 for storage.

[0042] Figure 6 Another perspective structural schematic diagram of a mobile charging station according to a specific embodiment of this application is shown, such as... Figure 1-6 As shown, it also includes a top cover 23, a first side cover 24 and a second side cover 25. The first side cover 24 and the second side cover 25 cooperate with the control compartment 04 to form a cavity for accommodating the battery 02 assembly and the heat dissipation compartment 05. The top cover 23 covers the control compartment 04, the heat dissipation compartment 05 and the mounting area.

[0043] Specifically, a first side cover 24 and a second side cover 25 are provided on both sides of the control compartment 04. The first side cover 24 on the same side is located above the second side cover 25. The first side cover 24 and the second side cover 25 are detachably connected to the side of the control compartment 04. The top cover 23, the first side cover 24, the second side cover 25 and the base 01 cooperate with each other to protect the internal structure of the charging pile. At the same time, the top cover 23, the first side cover 24 and the second side cover 25 can be disassembled individually, and different modules of the charging pile can be maintained individually according to maintenance needs.

[0044] Further preferably, the surfaces of the first side cover 24 and the second side cover 25 are also provided with a number of longitudinally arranged heat dissipation windows 26. Specifically, the heat dissipation windows 26 are distributed on the front, side and back of the charging pile, and the distribution density of the heat dissipation windows 26 is different according to the distribution density of the module. For example, the charging and discharging module 03 needs better heat dissipation during operation, so the first side cover 24 is provided with more heat dissipation windows 26 at the position corresponding to the charging and discharging module 03.

[0045] The mobile charging pile of this application utilizes a cross-shaped layout of the control compartment 04 and heat dissipation compartment 05 to rationally arrange the installation area and maximize space utilization. The charging and discharging module 03 and battery 02 are installed in a layered manner on the module bracket 07 and battery bracket 06. The fixedly installed module bracket 07 ensures structural strength, and the detachable connection of the battery bracket 06 allows for adjustment of the distribution of the battery bracket 06 according to the capacity and size of the battery 02 used, thereby increasing the capacity of the battery 02 carried by the charging pile. The modular layout also makes maintenance easier.

In this way, this utility model is also intended to cover such modifications and changes if they fall within the scope of the claims of this utility model and their equivalents. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are described in mutually different dependent claims does not indicate that a combination of these measures cannot be used for profit. Any reference numerals in the claims should not be considered as limiting the scope.
