Description

Technical Field

[0001] This utility model belongs to the field of battery pack protection technology, specifically relating to a battery pack protection device for electric loaders. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Currently, with the rapid development of the new energy industry, battery packs, as core components of new energy vehicles, have received widespread attention for their safety, protection performance, and reliability. In the protective design of battery packs, commonly used protective devices typically employ frameless enclosures made of composite materials such as aluminum alloys and plastics. While these materials provide some protection, they cannot offer sufficient strength and rigidity when facing extreme conditions such as collisions, drops, or compression during use. This can easily lead to deformation or damage to the battery pack casing, resulting in safety hazards such as internal battery short circuits and leakage. Utility Model Content

[0004] The purpose of this invention is to provide a battery pack protection device for electric loaders, which can at least solve one of the above-mentioned technical problems.

[0005] To achieve the above objectives, one or more embodiments of this utility model provide a battery pack protection device for an electric loader, comprising a battery frame and a protective steel plate. The battery frame includes supporting uprights, load-bearing horizontal plates, and a load-bearing base plate. The load-bearing horizontal plates are provided in multiple layers, and adjacent load-bearing horizontal plates are separated by supporting uprights. Supporting columns are provided on the load-bearing base plate and connected to both sides of the load-bearing horizontal plates along their length. The protective steel plate includes side protective plates and an upper protective plate. The side protective plates are connected to the side plates of the battery frame, and the upper protective plate is connected to the top of the battery frame.

[0006] Furthermore, the supporting upright plate is arranged on the symmetrical center line along the length direction of the load-bearing horizontal plate.

[0007] Furthermore, the horizontal projection dimension of the load-bearing base plate is larger than the horizontal projection dimension of the load-bearing cross plate.

[0008] Furthermore, the edge of the upper protective plate is bent to form a guide groove, and the opening of the guide groove faces outward of the protective device.

[0009] Furthermore, the bending direction of the guide channel forms an angle with the horizontal plane and extends along the length of the upper protective plate.

[0010] Furthermore, the upper half of the side protective plate in the width direction is an outwardly bent slope, and the lower half is perpendicular to the load-bearing base plate.

[0011] Furthermore, the top edge of the side protective plate is bolted to the battery frame, and the bottom edge is bolted to the battery frame.

[0012] Furthermore, the upper protective plate is bolted to the battery frame.

[0013] Furthermore, a handle is provided on the side protective plate.

[0014] Furthermore, the load-bearing base plate is connected to the loader frame by bolts.

[0015] The beneficial effects of one or more of the above technical solutions are as follows: This invention utilizes a combination of a battery frame and a protective steel plate to protect the battery pack and provide overall stability at the rear of the vehicle frame after installation. Under extreme conditions such as collisions, drops, or compression, the rigid connection of the frame effectively disperses external impact forces, preventing deformation or damage to the battery pack casing, thereby reducing safety hazards such as short circuits and leaks.

[0016] The upper protective plate has its edges bent to form a guide channel with the opening facing outwards. This allows it to quickly guide rainwater, oil, gravel, and other external debris away from the battery pack. The guide channel structure enhances the edge strength of the upper protective plate, reducing the risk of deformation. At the same time, it allows liquids and debris to drain in time, preventing the battery from overheating due to the accumulation of debris.

[0017] The side protection plate can be unfolded relative to the battery frame to increase ventilation gaps, avoid completely sealing the battery pack, facilitate heat dissipation, and improve heat dissipation performance. Attached Figure Description

[0018] The accompanying drawings, which form part of this application, are used to provide a further understanding of this application. The illustrative embodiments of this application and their descriptions are used to explain this application and do not constitute a limitation thereof.

[0019] Figure 1 This is a schematic diagram of the battery frame structure in one or more embodiments of the present invention; Figure 2 This is a schematic diagram of the installation of the battery frame and protective plate in one or more embodiments of this utility model.

[0020] In the diagram, 1 is the load-bearing horizontal plate; 2 is the supporting vertical plate; 3 is the load-bearing base plate; 4 is the supporting column; 5 is the upper protective plate; and 6 is the side protective plate. Detailed Implementation

[0021] like Figures 1 to 2 As shown, this embodiment provides a battery pack protection device for an electric loader, including a battery frame and a protective steel plate.

[0022] like Figure 1As shown, the battery frame includes a supporting upright plate 2, a load-bearing horizontal plate 1, and a load-bearing bottom plate 3; the protective plate includes a side protective plate 6 and an upper protective plate 5.

[0023] Specifically, the load-bearing horizontal plates 1 are arranged in at least three layers, with at least two battery packs symmetrically arranged in each layer along its length. Adjacent load-bearing horizontal plates 1 are separated by vertically welded support plates 2, which are located on the symmetrical center line along the length of the load-bearing horizontal plates 1, effectively separating two adjacent battery packs on the same horizontal plate and forming a regular battery housing space. Through the rigid connection between the support plates 2 and the load-bearing horizontal plates 1, a stable battery frame support system is formed, ensuring that the battery packs obtain reliable positioning and mechanical support in both the longitudinal and lateral directions.

[0024] Furthermore, the load-bearing base plate 3 is positioned below the load-bearing horizontal plate 1 and is bolted to the loader frame. A support plate 2 is installed between the load-bearing base plate 3 and the load-bearing horizontal plate 1, and support columns 4 are mounted on the load-bearing base plate 3. The support columns 4 are connected to both sides of the load-bearing horizontal plate 1 along its length, effectively transferring loads and improving anti-overturning performance. Moreover, the horizontal projection dimension of the load-bearing base plate 3 is significantly larger than that of the load-bearing horizontal plate 1, which helps to disperse load pressure, optimize load distribution, ensure foundation stability, and prevent localized overload.

[0025] The battery frame and protective plate are both treated with a topcoat, which significantly enhances corrosion resistance and extends the overall service life.

[0026] like Figure 2 As shown, the side protective plate 6 is connected to the side plate of the battery frame by bolts. The side protective plate 6 is equipped with a handle for easy operation and maintenance. The upper protective plate 5 covers the entire battery management system and is connected by bolts, providing comprehensive protection.

[0027] The edge of the upper protective plate 5 is formed into a continuous flow channel structure through a bending process, with the opening of the flow channel facing outwards from the protective device. The bending direction of the flow channel maintains an angle with the horizontal plane, which can effectively guide the flow of liquids or gravel. The entire flow channel extends linearly along the length of the upper protective plate 5, ensuring that the drainage and chip removal functions of the edge area of ​​the protective device are fully covered.

[0028] The working principle of this utility model: The battery pack protection device achieves its protective function through the battery frame and protective plates. The battery frame consists of a rigid support system composed of supporting uprights 2, load-bearing horizontal plates 1, and a load-bearing base plate 3: at least three layers of load-bearing horizontal plates 1 are used to symmetrically arrange the battery packs along the length direction, and the supporting uprights 2, which are perpendicularly welded to the center line of the horizontal plates, effectively separate adjacent battery packs and ensure the determination of the longitudinal and lateral positions between the battery packs. The load-bearing base plate 3 expands and distributes the load through its horizontal projection size, and its supporting columns 4 connect the two sides of the horizontal plates to transfer the load and improve the anti-overturning performance.

[0029] The protective panel consists of a side protective panel 6 and an upper protective panel 5. The top of the side protective panel 6 is bolted to the frame and can be unfolded to create a ventilation gap to promote heat dissipation. The bottom is bolted to enhance stability, and its upper half is bent outwards at an angle to optimize airflow guidance, while the lower half provides vertical support. The side protective panel 6 is equipped with a handle for easy unfolding. The upper protective panel 5 completely covers the top of the frame, with its edges bent to form continuous guide channels. The channel openings face outwards and are angled to guide liquid and gravel outwards.

[0030] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
