Description

Technical Field

[0001] The utility model relates to the technical field of battery swap stations, and in particular to a mini battery swap station and a battery swap assembly. Background Art

[0002] Currently, more efficient electric mining trucks are widely used in mining and transportation processes. Electric mining trucks require battery swap stations to meet the needs of battery replacement during use. Electric mining trucks require 7-8 batteries to be replaced in one hour of use, and it takes about 10 minutes to replace a battery. Therefore, in order to ensure that electric mining trucks can operate continuously, existing battery swap stations are usually equipped with 6-7 battery swap cabins to meet the high-frequency battery swap needs. However, in order to accommodate 6-7 battery swap cabins, these battery swap stations are large in size and cannot be transported as a whole from the production site to the mine site. They must be disassembled and assembled on site, which increases transportation and installation costs. In addition, battery swap stations essentially achieve battery replacement through mechanical movement, which has a certain failure rate. Existing battery swap stations usually only have one battery swap port. Once a failure occurs, it will directly affect the production operation of the mine and cause the risk of production interruption. Utility Model Content

[0029] Reference Figures 1 to 4 As shown, a mini battery swap station provided according to an embodiment of the present application includes a box body 100 and a battery swap system 200. The box body 100 includes a frame 110, side panels 120, a top panel 130, and an integrally formed bottom panel 140. The frame 110 is welded and fixed to the bottom panel 140. The side panels 120 and the top panel 130 are respectively mounted on the frame 110 and enclosed with the bottom panel 140 to form a battery swap cavity 150. The top panel 130 is provided with an openable and closable operating port 131. The side panel 120 located at one end of the box body 100 in the longitudinal direction is provided with an openable and closable battery swap port 121. Optionally, the frame 110 is formed by welding a plurality of aluminum profiles, and four corner connectors 111 are welded at the corners of the frame 110 to improve the overall strength of the frame 110.

[0030] The battery exchange system 200 is located in the battery exchange cavity 150. The battery exchange system 200 includes a transport device and multiple battery exchange cabins 210. The transport device is composed of a movable hoist and a clamp installed on the hoist. Since the market for transport devices in battery exchange stations is mature, there are many mature designs to choose from, which will not be described here. Multiple battery exchange cabins 210 are fixedly connected to the bottom plate 140 through the charging seat, and the transport device can drive the battery to be replaced to move between the battery exchange cabin 210 and the battery exchange port 121; the battery exchange system 200 also includes an openable and closable transformer cabinet 220. The transformer cabinet 220 is located at the end of the box 100 away from the battery exchange port 121. The charging seat is electrically connected to the transformer cabinet 220. The charging seat and the transformer cabinet 220 cooperate to convert external high-voltage AC power into low-voltage AC power or low-voltage DC power suitable for the charging seat. Optionally, an openable and closable monitoring room 151 is further provided in the battery exchange chamber 150 . The monitoring room 151 is arranged opposite to the transformer cabinet 220 to improve space utilization. The monitoring room 151 is used to monitor the status of each device in the battery exchange chamber 150 .

[0031] The number of the battery swap compartments 210 is less than or equal to four. For example, two, three or four battery swap compartments 210 can be provided in the battery swap cavity 150.

[0032] It can be understood that the box body 100 is designed and produced based on the one-piece molded bottom plate 140, and the battery exchange system 200 is integrated in the box body 100, so that the box body 100 and the internal battery exchange system 200 can be assembled into a whole when leaving the factory, effectively improving the overall and modular level of the mini battery exchange station.

[0033] By reducing the number of battery swap compartments 210 within the housing 100, the overall volume of the housing 100 can be reduced, keeping it within road transport standards. This allows for transport of the entire housing without disassembly, reducing material usage and manufacturing complexity for the mini-battery swap station. A single mini-battery swap station can meet basic battery swap needs, and multiple mini-battery swap stations can be deployed and used directly after being transported to the mine site. This effectively reduces the transportation and deployment costs of the mini-battery swap stations while still meeting high-frequency battery swap requirements.

[0034] Furthermore, the battery exchange system 200 also includes a transition cabin, which is located in the battery exchange cavity 150 at one end close to the battery exchange port 121, and the transition cabin and multiple battery exchange cabins 210 are arranged in a matrix shape. The transport device can drive the battery to be replaced to move between the transition cabin and the battery exchange port 121, or drive the battery to be replaced to move between the transition cabin and the battery exchange cabin 210.

[0035] When the mine car replaces the battery pack, it can first drive to the battery exchange port 121, the battery exchange port 121 is opened, and the handling device first transfers the empty old battery pack from the mine car to the transition cabin, and then installs the fully charged new battery pack from the battery exchange cabin 210 to the mine car, and finally transfers the old battery pack in the transition cabin to the battery exchange cabin 210 to take out the empty charging position pack of the battery, thereby completing the whole process of battery pack replacement. By setting up a transition cabin, the battery swap station can temporarily store the old battery pack when replacing the battery pack, protect the old battery pack, improve the continuity of the handling device operation, and improve the battery replacement efficiency. Optionally, two clamps of the handling device can be set, and the two clamps operate synchronously to synchronize the storage of the old battery pack and the replacement of the new battery pack. Further improve the battery replacement efficiency of the battery swap station.

[0036] Reference Figure 1 and Figure 3 As shown, it can be understood that the top plate 130 includes two long plates 132 and multiple intermediate plates 133. The long plates 132 are integrally formed parts. Along the length of the box 100, the length of the long plates 132 is equal to the length of the frame 110. The two long plates 132 are respectively welded to the frame 110, and an operation port 131 is formed between the two long plates 132. The multiple intermediate plates 133 are arranged along the length of the box 100, and the two sides of the intermediate plates 133 are detachably connected to the two long plates 132.

[0037] By providing long panels 132 that cover both sides of the container along their length, they provide continuous structural support, effectively improving the overall rigidity and stability of the roof panel 130, better distributing and withstanding external loads such as wind and snow pressure, and preventing deformation of the roof panel 130. Optionally, the intermediate panels 133 and the long panels 132 can be detachably connected by screwing, snapping, overlapping, or locking. The connection structure between the intermediate panels 133 and the long panels 132 is not specifically limited, as long as it ensures the overall vibration and impact resistance of the roof panel 130.

[0038] By providing a detachable intermediate plate 133, it is convenient for users to open and close the operating port 131, and thus facilitate the hoisting and assembly of the handling device from the outside of the container when the battery swap station is assembled. Specifically, the equipment on the top of the battery swap chamber 150, such as the beam of the handling equipment, can be pre-assembled outside the container and then placed as a whole in the battery swap chamber 150 of the box body 100. After the box body 100 is transported to the installation location at the mine, the intermediate plate 133 is removed and the handling equipment is hoisted, thereby reducing the on-site installation workload and improving assembly efficiency. In addition, when it is necessary to inspect the beam or internal equipment, it is only necessary to remove part of the intermediate plate 133 without moving the entire top plate 130, which effectively reduces the maintenance cost of the battery swap station in the later stage.

[0039] Furthermore, the top surface of the intermediate plate 133 is provided with a plurality of reinforcing portions 1331 , which are protruding structures protruding from the top plate 130 of the intermediate plate 133 formed by the upward depression of the bottom surface of the intermediate plate 133 . The plurality of reinforcing portions 1331 are arranged at intervals along the length direction of the box body 100 .

[0040] By providing the reinforcement portion 1331 , the curvature of the cross section of the middle plate 133 can be increased, compensating for the problem of thin wall and insufficient structural strength of the middle plate 133 , effectively improving the overall structural strength of the middle plate 133 , and further improving the structural stability of the top plate 130 .

[0041] Reference Figure 1 and Figure 4 As shown, it can be understood that the box body 100 is provided with multiple heat exchange devices 160, and the heat exchange devices 160 are arranged in a one-to-one correspondence with the power exchange compartments 210. Specifically, the heat exchange device 160 includes an exhaust fan arranged on the bottom surface of the box body 100, and the side panel 120 of the box body 100 is also provided with a louver 122, which is located on one side of the power exchange compartment 210.

[0042] When the battery swap cabin 210 is charging the battery pack, the exhaust fan starts, and the shutters 122 absorb external cold air into the battery swap chamber 150. After the cold air exchanges heat with the battery swap cabin 210, it flows out from the bottom of the box 100 through the exhaust fan, thereby dissipating heat and cooling the battery swap cabin 210. By providing the heat exchange device 160, the heat exchange device 160 can reduce the operating temperature of the battery swap cabin 210 and extend the service life of the battery swap cabin 210. In addition, the exhaust fan of the heat exchange device 160 is set at the bottom of the box 100, which can prevent external rainwater from entering the battery swap chamber 150 through the exhaust fan, effectively improving the waterproofness of the battery swap station.

[0043] Reference Figures 5 and 6 As shown, the embodiment of the present application also provides a battery swap assembly, including multiple mini battery swap stations and a lane 300. The lane 300 is used for the travel of mining vehicles, and the battery swap ports 121 of the multiple mini battery swap stations are all arranged toward the lane 300. Due to the small size and convenient layout of the mini battery swap station, the mini battery swap station can be directly arranged near the existing lane 300 of the mine, without the need for a separate battery swap channel, further simplifying the structure of the mini battery swap station.

[0044] Because a single mini-swap station utilizes an integrated, modular design, mass production of mini-swap stations can reduce unit costs, making the total cost of two mini-stations lower than that of a standard station. By setting up multiple mini-swap stations, the design and layout costs of the battery swap system 200 can be reduced. Furthermore, the battery swap ports 121 of multiple battery swap stations can independently perform battery swap operations, meeting higher battery swap demands while increasing design redundancy, improving the fault tolerance of the battery swap assembly, and ensuring the continuity of mine production.

[0045] Furthermore, the battery pack volumes in some mini-swap stations differ from those in other mini-swap stations. In other words, the multiple mini-swap stations that comprise the battery swap system 200 can accommodate battery packs of varying volumes. The corresponding handling devices, battery swap compartments 210, transition compartments, and charging stations for these different battery packs also differ, which will not be detailed here. This allows the battery swap requirements of mining trucks of varying load capacities to be met, allowing the same battery swap assembly to adapt to different mining trucks, effectively improving the assembly's practicality.

[0046] Reference Figure 5 As shown, it can be understood that there are two mini battery swap stations, which are arranged on both sides of the lane 300.

[0047] Setting the two battery swap stations opposite to each other can reduce the lateral size of the battery swap assembly in the direction of lane 300, and the battery swap ports 121 of the two opposite battery swap stations are symmetrically distributed on both sides of lane 300, which can facilitate the replacement of battery packs in mining cars and improve the battery swap efficiency of the battery swap assembly.

[0048] Reference Figure 6 As shown, it can be understood that there are two mini battery swap stations, which are arranged on the same side of the lane 300 and spaced apart along the direction of the lane 300.

[0049] The battery swap station is set up on the same side of lane 300 to avoid the battery swap assembly occupying the space on both sides of lane 300, making it convenient for on-site construction personnel to arrange other electrical equipment on the side of lane 300 where the battery swap assembly is not set up.

[0050] Reference Figure 7 As shown, it can be understood that the lane 300 includes two straight roads perpendicular to each other, and there are two mini battery swap stations. The two battery swap stations are located between the angles of the two straight roads and are arranged in an L shape. Specifically, the two battery swap stations are arranged perpendicular to each other, and the long side wall of one of the battery swap stations is flush with the short side wall end face of the battery swap port 121 of the other battery swap station.

[0051] The two battery swap stations are arranged in an L shape to adapt to the right-angle corner of lane 300, optimize the layout of the battery swap stations, reduce the overall volume of the battery swap assembly, and improve the space utilization of the battery swap assembly.

[0052] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
