Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and in particular to a novel power battery bracket. Background Technology

[0002] Current new energy vehicles mainly use electricity as their primary driving force, with power batteries driving motors to achieve vehicle propulsion. Most of the current power batteries are lithium batteries, which have many advantages such as high energy density and safety and reliability. When power batteries are installed on vehicles, they require battery brackets or battery packs for installation. A published Chinese patent (publication number: CN220652191U) describes a battery module mounting bracket with a buffering function, which includes a bracket and multiple elastic buffer devices. The elastic buffer devices include a housing, a lifting component, and elastic components. The housing is connected to the bracket, and the lifting component and elastic components are both disposed inside the housing. The two ends of the elastic components abut against the inner wall of the housing and the lifting component, respectively. This solution provides shock absorption for the mounting bracket.

[0003] The aforementioned battery module solves the problem of battery damage during transportation through an elastic buffer device, but it does not address the numerous drawbacks of current battery brackets, such as complex structure, heavy weight, and large size, which seriously affect vehicle driving efficiency and increase manufacturing costs. Utility Model Content

Detailed Implementation

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 1 As shown, a novel power battery bracket of this utility model includes a longitudinal beam 1, a transverse extension beam 2, a crossbeam 3, and a connector 4. The multiple crossbeams 3 are detachably connected vertically to the multiple longitudinal beams 1. Two sets of transverse extension beams 2 are respectively arranged at the bottom of both ends of the multiple longitudinal beams 1. The longitudinal beams 1 and the transverse extension beams 2 are detachably connected by multiple connectors 4.

[0024] Multiple crossbeams 3 are arranged perpendicularly to multiple longitudinal beams 1. The interior of each longitudinal beam 1 has a U-shaped cavity, and the diameter, length, and width of the longitudinal beam 1 are: The thickness is 1.5mm; the interior of the crossbeam 3 is also a U-shaped cavity, with one crossbeam 3 located at the bottom center of the longitudinal beam 1, and the diameter, length, and width of the crossbeam 3 are... The thickness is 1.2mm; three crossbeams 3 are evenly spaced on top of the longitudinal beam 1, and the diameter, length, and width of the three crossbeams 3 are... The thickness is 1.2mm.

[0025] The longitudinal beam 1 and the transverse extension beam 2 are detachably connected by multiple connectors 4, which solves the problem of the current connection method of welding between the battery bracket crossbeam 3 and the longitudinal beam 1, avoids excessive welding which increases the weight of the battery bracket, and improves the driving efficiency of the vehicle.

[0026] The transverse extension beam 2 includes multiple short crossbeams 21, which are connected by connectors 4.

[0027] The multiple short crossbeams 21 are also internally shaped cavities, with the diameter, length, and width of the short crossbeams 21 being... The thickness is 1.2mm.

[0028] By setting the transverse extension beam 2 to include multiple short crossbeams 21, the number of short crossbeams 21 can be selected according to the number of battery modules installed, thereby flexibly adjusting the size of the battery bracket, making the structure of the battery bracket simple to adjust and the volume of the battery bracket adjustable as needed.

[0029] It also includes support beams 3, and multiple support beams 3 are arranged vertically at intervals at the bottom of the longitudinal beam 1, and the multiple support beams 3 are detachably connected to the longitudinal beam 1.

[0030] Multiple support beams 3 are set at the bottom of the longitudinal beam 1, directly contacting the bottom of the battery module. On the one hand, this further increases the support force of the beams 3 to support the weight of the battery module. On the other hand, the battery module is fixed to the support beams 3 by bolts or fixing columns, which further improves the stability of the battery module and makes it less likely to shake during use.

[0031] like Figure 2 As shown, a reinforcing plate 11 is provided inside the longitudinal beam 1, and the reinforcing plate 11 is located at the bottom of the cavity of the longitudinal beam 1.

[0032] The longitudinal beam 1 and the connector 4 are connected by bolts, which can be quickly assembled and disassembled. When the number of battery modules increases, the volume of the mounting bracket needs to be expanded. At this time, it is only necessary to add the longitudinal beam 1 and the short crossbeam 21 of the transverse extension beam 2 to quickly build the frame of the mounting bracket. Then, the longitudinal beam 1 and the connector 4 are detachably connected by bolts to achieve quick installation and disassembly.

[0033] When the longitudinal beam 1 is connected to the connector 4, since the longitudinal beam 1 is a U-shaped beam, the longitudinal beam 1 and the connector 4 are connected by bolts, which will deform under stress. Therefore, a reinforcing plate 11 is set at the bottom of the cavity of the longitudinal beam 1 to increase the stress area and make the longitudinal beam 1 less prone to deformation under stress.

[0034] The longitudinal beam 1 is provided with a plurality of grooves 12, and the plurality of crossbeams 3 are engaged with the grooves 12 on the longitudinal beam 1 and are detachably connected.

[0035] To prevent displacement and sliding between the crossbeam 3 and the longitudinal beam 1, multiple grooves 12 are provided on the longitudinal beam 1. When the crossbeam 3 and the grooves 12 on the longitudinal beam 1 are engaged and fixed with bolts, the entire battery bracket becomes more robust and less prone to shaking.

[0036] The longitudinal beam 1 and the transverse beam 3 are connected by bolts. This allows for quick disassembly and reassembly of the modules when the required number of battery modules changes.

[0037] like Figure 3 As shown, a cross washer 6 is installed between the crossbeam 3 located at the bottom of the longitudinal beam 1 and the bolt.

[0038] The four "claws" of the cross washer 6 increase the bearing area, reducing bolt indentation or damage to the crossbeam. This prevents deformation or cracking of the crossbeam due to concentrated pressure during tightening. Furthermore, it increases friction, preventing bolts from loosening due to vibration or impact. The claws of the cross washer 6 can be adjusted to fit uneven contact surfaces, ensuring stable tightening.

[0039] It also includes lifting lug bolts 7, with multiple lifting lug bolts 7 disposed at both ends of the top of the longitudinal beam 1, and multiple lifting lug bolts 7 disposed at the connection between the top crossbeam 3 and the longitudinal beam 1.

[0040] The lifting lugs on the head of the lifting lug bolt 7 can be directly connected to hooks, wire ropes, or chains, simplifying the lifting, dragging, or suspension process without the need for additional welding or drilling. It can be used as a regular bolt fixing component and also as a lifting point, achieving "two uses in one." Multiple lifting lug bolts 7 can evenly distribute the tension during lifting, avoiding stress concentration and improving safety.

[0041] The connector 4 is a Z-shaped bracket. In addition to connecting the transverse extension beam 2 and the longitudinal beam 1, it also supports the entire mounting bracket to prevent it from sagging or shifting. The connector 4 with multiple Z-shaped brackets serves to distribute the weight of the pipeline, reduce vibration and stress concentration, facilitate adjustment of the installation height, and effectively provide seismic resistance and buffering.

[0042] The battery modules are placed on a horizontal support. There are a total of 6 modules in the figure. The number of modules can be increased or decreased according to the vehicle size and range requirements, such as a 4-module solution or an 8-module solution.

[0043] The battery bracket structure in this solution has a simple molding process for its sub-components and a simple connection process between them, which only requires standard connections. This avoids complex welding processes, improves the standardization requirements for mass production, greatly reduces manufacturing costs, and ensures that the overall structural strength meets the requirements.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
