Description

Technical Field

[0001] This invention relates to the field of commercial vehicles, specifically to a battery pack suspension bracket for a truss-type commercial vehicle. Background Technology

[0002] Existing commercial vehicle frames, such as truss or beam frames, vary in structure and load-bearing capacity, resulting in different installation spaces and layouts for battery packs. Due to the high price, large size, and heavy weight of battery packs, the battery pack suspension brackets require high structural strength, good installation precision, and easy assembly and disassembly to safely, accurately, and effectively suspend them on the commercial vehicle frame.

[0003] Especially for commercial vehicles with truss-type frames, whose frames are welded from profiles, the battery packs are heavy and expensive, weighing 600-1000 kg. Suspending the battery pack directly on the truss frame requires drilling mounting holes in the truss profiles. However, suspending the battery pack with additional holes in the profiles results in insufficient shear resistance and strength at the suspension points, making them prone to deformation or breakage. Furthermore, since the truss frame is welded from multiple profiles, drilling additional holes after welding makes it difficult to guarantee the accuracy of the hole positions matching the battery pack, easily leading to misalignment. Summary of the Invention

[0004] The technical problem this application aims to solve is to provide a battery pack suspension bracket for a truss-type commercial vehicle. The battery pack is suspended on the truss by a high-strength connecting plate and a suspension block, which improves the strength of the battery pack suspension part. Furthermore, the arrangement and hole positions of the connecting plate and the suspension block are designed according to the battery pack, ensuring the matching accuracy between the suspension bracket and the battery pack.

[0005] The specific technical solution of this application is as follows: a battery pack suspension bracket for a truss-type commercial vehicle, including a connecting plate and a suspension block. The connecting plate is attached to the truss of the vehicle chassis. One end of the suspension block is fixed to the connecting plate, and the other end of the suspension block is suspended. The side of the suspension block is folded inward to form a side wall, and a number of holes are provided on the suspension block.

[0006] Preferably, the connecting plate and the suspension block are made of 4mm steel.

[0007] Preferably, the hole on the suspension block is a screw hole.

[0008] Preferably, the suspended portion of the suspension block bends towards the battery pack and is flush with the connecting plate.

[0009] Furthermore, the connecting plate is also provided with mounting holes, which are suspended outside the truss.

[0010] More preferably, the connecting plate and the suspension block are fixed by screws and nuts, with the nuts welded to the connecting plate and the screws passing through the mounting holes and the holes in the suspension block.

[0011] Furthermore, the connecting plate is provided with several plug welding holes, and the connecting plate and the truss are fixed by welding.

[0012] Furthermore, it also includes a welding frame, which is vertically welded to the suspension block fixing surface of the connecting plate, and the wide side of the welding frame is welded to the lower surface of the truss.

[0013] More preferably, the welding frame is a right-angle frame, and the inner side of the right-angle frame abuts against one corner of the fixed end of the suspension block.

[0014] More preferably, the connecting plate is a one-piece elongated steel plate, and the length of the connecting plate is the same as the length or width of the battery pack.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention include: This application uses a high-strength connecting plate and a suspension block to suspend the battery pack on the truss. The inwardly folded sidewalls of the suspension block further improve the strength of the battery pack suspension part. Furthermore, the arrangement and hole positions of the connecting plate and the suspension block are designed according to the battery pack, ensuring the matching accuracy between the suspension bracket and the battery pack. One end of the suspension block is suspended to fix the battery pack in a suspended manner, which saves fixing space and cost, and also facilitates the installation and removal of the battery pack from the truss.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Therefore, the following detailed description of embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely illustrates some embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] Example Please see Figures 1 to 5 This embodiment provides a battery pack suspension bracket for a truss-type commercial vehicle, including a connecting plate 1 and a suspension block 2. The connecting plate 1 is attached to the truss 100 of the vehicle chassis. One end of the suspension block 2 is fixed to the connecting plate 1, and the other end of the suspension block 2 is suspended. The side of the suspension block 2 is folded inward to form a side wall, and several holes are provided on the suspension block 2. The high-strength connecting plate 1 and suspension block 2 suspend the battery pack on the truss 100. The inward folded side wall of the suspension block 2 further improves the strength of the battery pack suspension part. Furthermore, the arrangement and hole positions of the connecting plate 1 and suspension block 2 are designed according to the battery pack, ensuring the matching accuracy between the suspension bracket and the battery pack. The suspension block 2, with one end suspended, fixes the battery pack in a suspended manner, which saves fixing space and cost, and also facilitates the installation and removal of the battery pack from the truss 100.

[0020] Preferably, the connecting plate 1 and the suspension block 2 are made of 4mm steel. The connecting plate 1 and the suspension block 2, made of thicker steel, have higher strength and stronger shear resistance when suspending the battery pack, further avoiding the risk of deformation or cracking of the battery pack suspension part.

[0021] Preferably, the holes on the suspension block 2 are screw holes 21. The four screw holes 21 on the suspension part of the suspension block 2 match the battery pack, which facilitates the tightening of the screws 4 during installation to fix the battery pack, and facilitates the disassembly and installation of the battery pack.

[0022] Preferably, the suspended portion of the suspension block 2 is bent towards the battery pack and flush with the connecting plate 1. The contact surface of the suspension block 2 is fixed to the connecting plate 1, and the contact surface of the suspended portion of the suspension block 2 is flush with the battery pack side surface of the connecting plate 1 after bending, which facilitates the assembly and disassembly of the battery pack; the forces on the suspension block 2 and the connecting plate 1 are in a straight line, further avoiding the risk of deformation or cracking of the battery pack suspension portion.

[0023] Furthermore, the connecting plate 1 is also provided with mounting holes 11, which are suspended outside the truss 100. The connecting plate 1 and the suspension block 2 are fixed by screws 4 and nuts 3. The nuts 3 are welded to the connecting plate 1, and the screws pass through the mounting holes 11 and the screw holes 21 of the suspension block 2. All fastening parts are suspended outside the truss 100, allowing the battery pack to be installed and removed from between the trusses 100, avoiding interference from the trusses 100 during the installation and removal process, and further facilitating the installation and removal of the battery pack.

[0024] Furthermore, the connecting plate 1 is provided with a plurality of plug weld holes 12, and the connecting plate 1 and the truss 100 are fixed by welding. Welding the connecting plate 1 to the truss 100 avoids the need for additional drilling on the truss 100, which would affect the strength of the truss 100. Providing multiple plug weld holes 12 improves the welding strength between the connecting plate 1 and the truss 100, and prevents the welded position from cracking and failing due to the weight of the battery pack.

[0025] Furthermore, it also includes a welding frame 13, which is vertically welded to the fixing surface of the suspension block 2 of the connecting plate 1, and the wide side of the welding frame 13 is welded to the lower surface of the truss 100. The truss 100 of commercial vehicles generally uses square tube profiles. The connecting plate 1 and the welding frame 13 are welded at right angles to the side and bottom surfaces of the square tube. In this embodiment, the welding frame 13 is set in the part with greater stress to improve the welding strength and further prevent welding failure.

[0026] More preferably, the welding frame 13 is a right-angle frame, with its inner side abutting against one corner of the fixed end of the suspension block 2. In this embodiment, the parts subjected to greater force are generally the fixed positions of the suspension block 2 and the connecting plate 1. The right-angle frame can improve welding strength while providing installation positioning for the suspension block 2, facilitating its installation. Since the mounting holes 11 of the connecting plate 1 are set according to the matching position of the battery pack, the right-angle frame can also restrict the installation position of the suspension block 2, thereby further improving the matching accuracy between this embodiment and the battery pack.

[0027] More preferably, the connecting plate 1 is a one-piece elongated steel plate, and the length of the connecting plate 1 is the same as the length or width of the battery pack. The one-piece design and manufacturing of the steel plate can significantly improve the strength of the connecting plate 1 and further improve the ability of the connecting plate 1 to suspend the battery pack.
