[0041] In related technologies, heavy-duty trucks can adopt a rear-mounted battery swapping mode. The heavy-duty truck has a battery system cabinet located behind the cab, and power is replenished by replacing the battery system cabinet. The battery swapping process is as follows: the heavy-duty truck is driven into the designated swapping area of ​​the heavy-duty truck battery swapping station. Then, the swapping station's system obtains vehicle information (such as vehicle model and battery type) through scanning or identification technology. Next, the station's robotic arm picks up the battery system cabinet from above and replaces it. Finally, after checking the heavy-duty truck's battery status, connection status, and other conditions, the heavy-duty truck leaves the swapping station to continue its transportation mission.

[0042] The battery system cabinet includes components such as battery cells, battery piping systems, and cooling systems. These components work together to provide power to the heavy-duty truck. The battery system cabinet also includes a main cabinet body. The battery cells, battery piping systems, and cooling systems are installed inside the main cabinet body. The main cabinet body includes a support frame and an outer shell fixed to the outside of the support frame. The outer shell can be made of steel plate using sheet metal processing. The support frame can be made of steel pipes through welding to ensure the strength and stability of the main cabinet body.

[0043] However, in cold weather, the chemical reaction rate of the battery cells in the battery system cabinet slows down, resulting in low power output efficiency and a decrease in battery capacity and range.

[0044] To address the aforementioned issues, this application provides an insulation structure, a battery system cabinet, and a heavy-duty truck. The heavy-duty truck includes a battery system cabinet that provides electrical power to the truck. The battery system cabinet includes an insulation structure and a cabinet body. The insulation structure is used to surround the outside of the battery system cabinet body. The insulation structure is detachably connected to the battery system cabinet body. An opening is provided at the bottom of the insulation structure, allowing a mounting base of the battery system cabinet to pass through, thus avoiding interference with the installation and securing of the battery system cabinet body. One or more clearance openings are provided at the top of the insulation structure, through which a robotic arm can grasp the battery system cabinet body for replacement. The insulation structure reduces heat exchange between the inside and outside of the battery system cabinet body, thereby reducing temperature drops within the battery system cabinet body, ensuring the chemical reaction rate of the battery cells, improving power output efficiency, and enhancing the battery capacity and range of the battery system cabinet body.

[0045] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0046] This application provides a heavy-duty truck, including the insulation structure or battery system cabinet described below. The heavy-duty truck can be used in scenarios such as ports, steel mills, power plants, and mines.

[0047] Reference Figure 1 As shown in the figure, this application embodiment provides a battery system cabinet 10. The battery system cabinet 10 can be applied to heavy-duty trucks to provide power to them. The battery system cabinet 10 includes a thermal insulation structure 100 as described below. The outer cover of the battery system cabinet body 200 is provided with a thermal insulation structure to ensure the performance of the battery system cabinet.

[0048] Reference Figure 1 and Figure 2 As shown in the illustration, this application provides a thermal insulation structure 100, which is detachably connected to the battery system cabinet 200. The thermal insulation structure 100 can be installed on or removed from the battery system cabinet 200 as needed. This facilitates thermal insulation of the battery system cabinet 200 under different environments, and also facilitates the maintenance and replacement of the thermal insulation structure 100.

[0049] For example, the insulation structure 100 can be made of insulation material. The insulation material has low thermal conductivity, which can reduce heat exchange between the inside and outside of the battery system cabinet 200, thereby reducing the temperature drop inside the battery system cabinet 200.

[0050] When heavy-duty trucks adopt a rear-mounted battery swapping mode, a robotic arm can be used to grasp and replace the battery system cabinet 200. The top of the insulation structure 100 is provided with one or more clearance openings 111, which can be used for the robotic arm to pass through, allowing the robotic arm to grasp the battery system cabinet 200 and thus replace it. This helps improve battery swapping efficiency and reduce time costs during the swapping process.

[0051] For example, depending on the position where the robotic arm and the battery system cabinet 200 are engaged, the insulation structure 100 can be provided with an avoidance opening 111 at the corresponding position to reduce the size of the avoidance opening 111 and ensure the insulation effect of the insulation structure 100.

[0052] For example, the clearance 111 can be designed according to the shape of the support frame of the battery system cabinet 200 to reduce the design and processing difficulty of the insulation structure 100.

[0053] Reference Figure 2 As shown, the bottom end of the insulation structure 100 is provided with an opening 101, which allows the mounting base of the battery system cabinet 200 to pass through. This design avoids affecting the installation and fixation of the battery system cabinet 200.

[0054] The thermal insulation structure 100 can be used to surround the outside of the battery system cabinet 200. The thermal insulation structure 100 can reduce heat exchange between the inside and outside of the battery system cabinet 200, thereby reducing the temperature drop inside the battery system cabinet 200, thus ensuring the chemical reaction rate of the battery cells, improving power output efficiency, and improving the battery capacity and range of the battery system cabinet 200.

[0055] The thermal insulation structure 100 can be used for thermal insulation of cabinets such as new energy storage cabinets, control cabinets, power distribution cabinets, integrated charging and storage battery swapping cabinets, combined charging and storage battery swapping cabinets, and large-scale combined storage battery swapping cabinets.

[0056] The insulation structure 100 is made of fiber cloth. Fiber cloth is lightweight and high-strength, which can reduce the weight of the insulation structure 100 while maintaining its strength.

[0057] The fiber fabric comprises a coated fiber layer, a fiber blanket layer, and another coated fiber layer stacked sequentially. The coated fiber layer improves the flatness and moisture resistance of the insulation structure 100. The fiber blanket layer is lightweight and flexible, reducing the weight of the fiber fabric. By stacking the coated fiber layer, fiber blanket layer, and coated fiber layer, the advantages of different materials can be combined, enabling the fiber fabric to achieve better thermal insulation performance.

[0058] If the thickness of the insulation structure 100 is less than 10mm, its insulation performance will not meet the usage requirements. If the thickness of the insulation structure 100 is greater than 20mm, it will increase its weight and cost. Therefore, the thickness of the insulation structure 100 can be 10-20mm to ensure its insulation performance.

[0059] For example, taking into account factors such as the weight, cost, and insulation performance of the insulation structure 100, the thickness of the insulation structure 100 can be 15mm.

[0060] Reference Figure 3 As shown, in some embodiments, the insulation structure 100 includes an insulation body 120 and an upper insulation component 110. The insulation body 120 surrounds the battery system cabinet 200, which can reduce heat loss and ensure the insulation performance of the insulation structure 100. The insulation body 120 can wrap around the battery system cabinet 200, which can prevent physical damage such as impact to the battery system.

[0061] The insulation structure 100 includes a connecting component 300. The connecting component 300 can be used to connect the insulation body 120 and the upper insulation component 110. The connecting component 300 can also be used to connect the insulation body 120 to the battery system cabinet 200 or the upper insulation component 110 to the battery system cabinet 200.

[0062] The connecting component 300 includes one or more of the following: Velcro, metal buckles, cable ties, straps, and fasteners. The connecting component 300 is common and easy to operate, improving the convenience of disassembling and installing the insulation structure 100, and facilitating the installation, maintenance, and replacement of the insulation structure 100.

[0063] The top of the insulation body 120 is detachably connected to the battery system cabinet 200 via the connecting component 300 to improve the ease of disassembly and installation of the insulation body 120.

[0064] For example, multiple straps are threaded through the top edge of the insulation body 120. The insulation body 120 can be tied to the steel pipe of the support frame using the straps, reducing the difficulty of installing and disassembling the insulation body 120.

[0065] The top of the insulation body 120 is detachably connected to the upper insulation component 110 via a connecting assembly 300. This improves the ease of disassembly and installation of the upper insulation component 110.

[0066] For example, the top edge of the insulation body 120 is provided with a hook-and-loop fastener, and the upper insulation component 110 is provided with a hook-and-loop fastener at a corresponding position. The insulation body 120 is detachably connected to the upper insulation component 110 via the hook-and-loop fastener and the hook-and-loop fastener.

[0067] The insulation body 120 includes multiple insulation components. These components include a front insulation component 130, a rear insulation component 140, a left insulation component 150, and a right insulation component 160. The insulation body 120 can be disassembled into smaller insulation components, which can be produced using automated equipment, facilitating the production of the insulation structure 100 and improving its production efficiency.

[0068] Reference Figure 4 As shown, two adjacent insulation components among the front insulation component 130, rear insulation component 140, left insulation component 150, and right insulation component 160 are detachably connected via a connecting assembly 300, facilitating their assembly into the insulation body 120. The insulation body 120 can be assembled from multiple insulation components, reducing the installation difficulty and improving the installation efficiency.

[0069] The connecting assembly 300 includes a detachably connected first connector 310 and a second connector 320. One of two adjacent insulation components is provided with the first connector 310, and the other of two adjacent insulation components is provided with the second connector 320. The two adjacent insulation components are detachably connected to each other via the first connector 310 and the second connector 320. This arrangement prevents the two adjacent insulation components from separating during use, improving the reliability of the insulation structure 100.

[0070] For example, the first connector 310 and the second connector 320 can be respectively set as the hook side and the rough side of the Velcro, and the two adjacent insulation parts can be connected by connecting the hook side and the rough side.

[0071] In some embodiments of this application, at least one of the front insulation member 130, rear insulation member 140, left insulation member 150, and right insulation member 160 includes an extension area at its edge, and a first connector 310 or a second connector 320 is disposed in the extension area. When two adjacent insulation members are connected, the extension area can be folded onto the connected insulation member to enhance the airtightness of the insulation structure 100 and improve the insulation effect of the insulation structure 100.

[0072] In some embodiments, the insulation structure 100 includes an air inlet insulation component 161 and an air outlet insulation component 141. The air inlet insulation component 161 is correspondingly disposed with respect to the air inlet of the battery system cabinet 200, and is detachably connected to the insulation structure 100. The air outlet insulation component 141 is correspondingly disposed with respect to the air outlet of the battery system cabinet 200, and is detachably connected to the insulation structure 100. The air inlet insulation component 161 and the air outlet insulation component 141 can be detached from the insulation structure 100, allowing the air inlet and air outlet to communicate with the surrounding environment. The air from the surrounding environment can circulate from the air inlet to the air outlet, achieving heat dissipation for the battery system cabinet 10, thereby reducing the temperature of the battery system cabinet 10 and ensuring its normal operation.

[0073] Furthermore, by removing the inlet insulation component 161 and the outlet insulation component 141 from the insulation structure 100, heat dissipation of the battery system cabinet 200 can be achieved. This design eliminates the need to disassemble the entire insulation structure 100, thereby improving the convenience of adjusting the heat dissipation of the battery system cabinet 200.

[0074] For example, after the heavy truck starts, the temperature of the battery system cabinet 10 rises. The air inlet insulation component 161 is removed from the insulation structure 100 to allow air convection in the battery system cabinet 10, thereby reducing the temperature of the battery system cabinet 10 and ensuring its normal operation.

[0075] In some embodiments, the inlet insulation component 161 and the outlet insulation component 141 are detachably connected to the insulation structure 100 via the connecting assembly 300 to improve the convenience of the inlet insulation component 161 and the outlet insulation component 141.

[0076] In some embodiments, the insulation structure 100 includes a charging port insulation component 151, which is configured to correspond to the charging port of the battery system cabinet 200. The charging port insulation component 151 is detachably connected to the insulation structure 100. The charging port insulation component 151 can be detached from the insulation structure 100, allowing the charging port of the battery system cabinet 10 to be connected to external devices (e.g., charging equipment) to enable charging or discharging of the battery system cabinet 10.

[0077] Furthermore, after removing the charging port insulation component 151 from the insulation structure 100, the battery system cabinet 200 can be charged or discharged. This design eliminates the need to disassemble the entire insulation structure 100, improving the convenience of charging and discharging the battery system cabinet 200.

[0078] In some embodiments, the charging port insulation component 151 is detachably connected to the insulation structure 100 via the connecting assembly 300 to improve the convenience of the charging port insulation component 151.

[0079] In some embodiments, the insulation structure 100 includes a maintenance port insulation component 152, which is configured to correspond to the maintenance port of the battery system cabinet 200. The maintenance port insulation component 152 is detachably connected to the insulation structure 100. The maintenance port insulation component 152 can be removed from the insulation structure 100, allowing the maintenance port of the battery system cabinet 10 to be connected to external equipment for troubleshooting and maintenance of the battery system cabinet 10.

[0080] Furthermore, the insulation component 152 of the maintenance access panel in the insulation structure 100 allows for troubleshooting and repair of the battery system cabinet 200. This design eliminates the need to disassemble the entire insulation structure 100, thus improving the ease of maintenance for the battery system cabinet 200.

[0081] In some embodiments, the maintenance port insulation component 152 is detachably connected to the insulation structure 100 via the connecting assembly 300 to improve the convenience of the maintenance port insulation component 152.

[0082] The battery system cabinet 200 is equipped with a mounting base, which is used to mount the battery system cabinet 200 onto the heavy truck to ensure that the battery system cabinet 200 does not move during the operation of the heavy truck, thus making the heavy truck transportation reliable.
