Description

Technical Field

[0001] This utility model relates to the field of vehicle auxiliary equipment technology, and in particular to a vehicle battery cabinet. Background Technology

[0002] With the widespread application of mining dump trucks in mining and other fields, the transformation of their power sources is also continuously advancing. As a key component of the new power system of mining dump trucks, battery packs have special requirements for their storage and protection. Traditional battery storage devices are often structurally simple and difficult to adapt to the complex and demanding working environment of mining dump trucks.

[0003] In mining operations, mining dump trucks face a variety of harsh conditions, including bumps, vibrations, dust, and humidity fluctuations. This requires that the vehicle battery cabinets used to house the battery packs not only have good stability to protect the batteries from damage caused by shaking during vehicle operation, but also have a reasonable layout structure to optimize the placement of the battery packs, improve space utilization, and ensure the heat dissipation performance of the battery packs.

[0004] Furthermore, battery packs typically involve complex pipeline connections, which are susceptible to loosening and wear due to external interference during vehicle operation. This can affect the normal operation of the battery pack and the overall safety and reliability of the vehicle. Previous battery cabinet designs lacked effective limiting and protection measures for the battery pack pipelines, failing to meet the needs of mining dump trucks operating under long-term, high-intensity conditions. Utility Model Content

[0005] The purpose of this utility model is to provide a vehicle battery cabinet that, through a unique double-layer frame structure, achieves efficient utilization of limited space, greatly expanding the placement space of the battery pack without increasing the floor area. The rationally set multiple partition mechanisms and limiting components realize the stable positioning of the battery pack and the orderly management of pipelines, which greatly reduces the risk of battery displacement and collision during vehicle driving vibration and the risk of pipeline wear and short circuit, thereby improving the stability and safety of the battery pack.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] This utility model provides a vehicle battery cabinet for accommodating a battery pack of a mining dump truck. The vehicle battery cabinet includes a first frame and a second frame mounted on top of the first frame. The first frame includes multiple first partitioning mechanisms for dividing multiple first battery placement areas to place multiple batteries of the battery pack. The second frame includes multiple second partitioning mechanisms for dividing multiple second battery placement areas to place multiple batteries of the battery pack. The number of second partitioning mechanisms is less than the number of first partitioning mechanisms. The vehicle battery cabinet also includes multiple limiting members connected between the first partitioning mechanisms and the multiple second partitioning mechanisms. The multiple limiting members together form a limiting structure for limiting the pipelines of the battery pack.

[0008] Specifically, in this embodiment, the first separating mechanism includes a plurality of first battery brackets for supporting the battery pack, and the limiting member is installed between adjacent first battery brackets.

[0009] Specifically, in this embodiment, the first battery bracket includes a first support plate for supporting the battery pack and a first divider connected to the first support plate for dividing the plurality of first battery placement areas.

[0010] Specifically, in this embodiment, there are multiple first separators, and the length direction of a portion of the multiple first separators is perpendicular to the length direction of another portion of the first separators.

[0011] Specifically, in this embodiment, the end of the first bearing plate is provided with a plurality of first bearing blocks, and the plurality of first bearing blocks are respectively connected to the plurality of first separators.

[0012] Specifically, in this embodiment, a portion of the limiting member is housed within the first frame, forming a first limiting space within the first frame.

[0013] Specifically, in this embodiment, the second separating mechanism includes a plurality of second battery brackets installed in the second frame for carrying the battery pack, and another part of the limiting member is accommodated in the second frame, forming a second limiting space within the second frame.

[0014] Specifically, in this embodiment, the second limiting space is formed on top of the first limiting space, and the limiting member is vertically connected to the first battery bracket and the second battery bracket to connect the first limiting space in the first frame and the second limiting space in the second frame to form the limiting structure.

[0015] Specifically, in this embodiment, the second frame further includes a support mechanism for carrying the thermal management system, which is installed on the side of the second partition structure.

[0016] A mining dump truck includes a vehicle battery cabinet, a battery pack, a thermal management system, and a frame as described in this embodiment, characterized in that the battery pack and the thermal management system are mounted on the vehicle battery cabinet, and the vehicle battery cabinet is mounted on the frame.

[0017] This utility model provides a vehicle battery cabinet for accommodating battery packs of mining dump trucks. It includes a first frame and a second frame mounted on top of the first frame. The first frame includes multiple first partitioning mechanisms for dividing multiple first battery placement areas to accommodate multiple batteries of the battery pack. The second frame includes multiple second partitioning mechanisms for dividing multiple second battery placement areas to accommodate multiple batteries of the battery pack. The number of second partitioning mechanisms is less than the number of first partitioning mechanisms. The vehicle battery cabinet also includes multiple limiting members connecting the first partitioning mechanisms and the multiple second partitioning mechanisms. These limiting members together form a limiting structure for limiting the wiring of the battery pack. Through a unique double-layer frame structure, efficient use of limited space is achieved, greatly expanding the battery pack placement space without increasing the floor area.

[0028] like Figures 1 to 3As shown, the preferred embodiment of this utility model provides a vehicle battery cabinet for accommodating battery packs of mining dump trucks. It includes a first frame 1 and a second frame 2 mounted on top of the first frame 1. The first frame 1 includes multiple first partitioning mechanisms 11 for dividing multiple first battery placement areas to accommodate multiple batteries of the battery pack. The second frame 2 includes multiple second partitioning mechanisms 21 for dividing multiple second battery placement areas to accommodate multiple batteries of the battery pack. The number of second partitioning mechanisms 21 is less than the number of first partitioning mechanisms 11. The vehicle battery cabinet also includes multiple limiting members 33 connecting the first partitioning mechanisms 11 and the multiple second partitioning mechanisms 21. The multiple limiting members 33 together form a limiting structure 3 for limiting the pipelines of the battery pack. Through the unique double-layer frame structure, efficient use of limited space is achieved, greatly expanding the battery pack placement space without increasing the floor area. The rationally arranged multiple partitioning mechanisms and limiting members 33 realize stable limiting of the battery pack and orderly management of the pipelines, greatly reducing the risk of battery displacement and collision during vehicle vibration and the risk of pipeline wear and short circuit, thus improving the stability and safety of the battery pack.

[0029] Specifically, multiple first separation mechanisms 11 and second separation mechanisms 21 precisely separate and fix the battery, enhancing the stability of the battery pack, effectively suppressing battery displacement and collisions during vehicle operation, reducing the risk of battery damage, ensuring reliable operation of the power system, significantly reducing vehicle downtime, ensuring the continuity of mining dump truck operations, and improving production efficiency. Simultaneously, the limiting structure 3, formed by multiple limiting components 33 connected between the first separation mechanism 11 and the second separation mechanism 21, effectively limits the battery pack pipelines, preventing problems such as pipeline shaking, tangling, wear, and short circuits, extending pipeline lifespan, ensuring pipeline neatness and order, facilitating later maintenance and repair work, reducing maintenance costs and difficulty, and further improving the overall reliability and maintainability of the vehicle.

[0030] In this embodiment, the first separation mechanism 11 includes a plurality of first battery brackets 111 for supporting the battery pack. The limiting member 33 is installed between adjacent first battery brackets 111 and is tightly connected to the first battery brackets 111. It provides lateral limiting for the battery pack placed on the first battery brackets 111 to prevent the battery from sliding in the horizontal direction due to the movement of the vehicle, thereby protecting the battery from damage. The limiting member 33 is also connected upward to the second separation mechanism 21 to form a three-dimensional limiting net from bottom to top and from horizontal to vertical. This not only restricts the overall displacement of the battery pack, but also constrains the pipelines of the battery pack, ensuring that the pipelines are arranged along a preset path.

[0031] In this embodiment, the first battery holder 111 includes a first support plate 112 for supporting the battery pack and a first partition 113 connected to the first support plate 112 for dividing multiple first battery placement areas. The first partition 113 is specifically a rectangular tube perpendicularly connected to the first support plate 112. The first partition 113 and the first support plate 112 together constitute the first battery holder 111 unit. Multiple units are combined to form a first partition structure, which is then connected to the second partition mechanism 21 of the second frame 2 through the limiting member 33 to construct a complete battery accommodating and limiting system.

[0032] Specifically, there are multiple first partitions 113, and the length direction of a portion of the multiple first partitions 113 is perpendicular to the length direction of another portion of the first partitions 113.

[0033] In this embodiment, the end of the first support plate 112 is provided with a plurality of first support blocks 114. The plurality of first support blocks 114 are respectively connected to a plurality of first separators 113. The first support blocks 114 are square in shape and are fixed on both sides of the first support plate 112, with two on each side. The first support blocks 114 are connected to the first separators 113 and are used to support the first support plate 112 and the battery on the first support plate 112.

[0034] In this embodiment, a portion of the limiting member 33 is housed within the first frame 1, enclosing a first limiting space 31 within the first frame 1. The limiting member 33, housed within the first frame 1, serves as the boundary of the first limiting space 31 and is tightly connected to the first battery bracket 111. On one hand, it relies on the structural support of the first battery bracket 111 to maintain its own positional stability, thereby ensuring the shape and size of the first limiting space 31 are fixed. On the other hand, through its own limiting function, it constrains the displacement of the battery pack, preventing interference between the battery and the pipelines within the first limiting space 31. Simultaneously, the first limiting space 31 extends upwards and coordinates with the relevant structures of the second frame 2 to jointly construct a continuous and complete pipeline limiting system from the first frame 1 to the second frame 2.

[0035] In this embodiment, the second partition mechanism 21 includes a plurality of second battery brackets 211 for supporting battery packs installed in the second frame 2, and another part of the limiting member 33 is accommodated in the second frame 2, forming a second limiting space 32 in the second frame 2; the second battery bracket 211 includes a second support plate 212 for supporting battery packs on the second frame 2 and a second partition member 213 connected to the second support plate 212. The end of the second support plate 212 is provided with a plurality of second support blocks 214, and the second support blocks 214 are connected to the second partition member 213 for supporting the second support plate 212 and the batteries on the second support plate 212.

[0036] Specifically, the second limiting space 32 is formed at the top of the first limiting space 31, and the limiting member 33 is vertically connected to the first battery bracket 111 and the second battery bracket 211 to connect the first limiting space 31 in the first frame 1 and the second limiting space 32 in the second frame 2 to form the limiting structure 3.

[0037] Specifically, the second limiting space 32 and the first limiting space 31 within the first frame 1 are interconnected by the limiting member 33, together forming a pipeline limiting system that runs through the entire battery cabinet. The connected limiting mechanism provides a complete and continuous constraint channel for the pipelines of the battery pack, so that the pipelines from the first frame 1 to the second frame 2 can be effectively constrained and protected.

[0038] In this embodiment, the second frame 2 also includes a support mechanism 22 installed on the side of the second partition structure for carrying the thermal management system. The thermal management system can accurately regulate the temperature and avoid overheating that causes battery capacity decay and power reduction, as well as overcooling that causes charging and discharging difficulties and increased internal resistance.

[0039] Another embodiment of this application provides a mining dump truck, including a vehicle battery cabinet, a battery pack, a thermal management system, and a frame as described in this embodiment. The battery pack and the thermal management system are mounted on the vehicle battery cabinet, which is mounted on the frame.

[0040] The vehicle battery cabinet provided by this utility model is used to accommodate the battery pack of a mining dump truck. It includes a first frame 1 and a second frame 2 installed on top of the first frame 1. The first frame 1 includes multiple first partitioning mechanisms 11 for dividing multiple first battery placement areas to place multiple batteries of the battery pack. The second frame 2 includes multiple second partitioning mechanisms 21 for dividing multiple second battery placement areas to place multiple batteries of the battery pack. The number of second partitioning mechanisms 21 is less than the number of first partitioning mechanisms 11. The vehicle battery cabinet also includes multiple limiting members 33 connecting the first partitioning mechanisms 11 and the multiple second partitioning mechanisms 21. The multiple limiting members 33 together form a limiting structure 3 for limiting the pipelines of the battery pack. Through the unique double-layer frame structure, the limited space is efficiently utilized, and the placement space of the battery pack is greatly expanded without increasing the floor area. The reasonable arrangement of multiple partitioning mechanisms and limiting members 33 realizes the stable limiting of the battery pack and the orderly management of the pipelines, which greatly reduces the displacement and collision risk of the battery during vehicle driving vibration and the wear and short circuit of the pipelines, and improves the stability and safety of the battery pack.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
