Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, and in particular to a frame-type battery bracket structure. Background Art

[0002] Currently, the new energy pure electric commercial vehicles on the market primarily consist of low-capacity trucks, box-type transport trucks, and urban sanitation vehicles. The power battery layout primarily consists of side-mounted and internally mounted batteries, and a combination thereof. With the exception of micro trucks, side-mounted batteries have become the mainstream in the new energy low-capacity vehicle market. Statistics show that the mass of a side-mounted power battery pack for commercial vehicles is approximately 250-400kg per side, and the weight is relatively concentrated. Existing new energy cargo, transport, and sanitation vehicles primarily operate on highways, urban roads, and national highways, which significantly impacts the impact load on the power battery frame during actual use. However, the operating conditions and scenarios of pure electric dump trucks differ significantly from those of these vehicles. Therefore, the traditional truck power battery frame structure cannot meet the needs of new energy dump trucks. Furthermore, with the increasing market demand for new energy low-capacity dump trucks, research on new energy power battery frame structures is particularly urgent. Utility Model Content

[0030] Example 1

[0031] A frame-type battery support structure includes two longitudinal beam assemblies 1, two battery frame assemblies 2, two cross beam assemblies 3, and two lateral stabilizer bars 4. The two longitudinal beam assemblies 1 extend in the front-to-back direction and are arranged parallel to the left and right sides. The two battery frame assemblies 2 are respectively installed on the outside of the two longitudinal beam assemblies 1.

[0032] The battery frame assembly 2 includes two baffles 21, several intermediate brackets 22 and a frame. The two baffles 21 are installed on the outside of the longitudinal beam assembly 1 in sequence, and the front and rear ends of the frame are connected to the two baffles 21 respectively. The intermediate bracket 22 is L-shaped and is used to connect the outside of the longitudinal beam assembly 1 and the bottom of the frame. The frame includes four longitudinal rods 23, several cross braces 24 and several columns 25. The two ends of the four longitudinal rods 23 are symmetrically connected to the upper left, upper right, lower left and lower right parts of the two baffles 21 respectively. The cross braces 24 extend in the left-right direction to connect the two longitudinal rods 23 below, and the columns 25 extend in the vertical direction to connect the upper and lower longitudinal rods 23 on both sides.

[0033] The lateral stabilizer bars 4 extend in the left-right direction, and one end of the two lateral stabilizer bars 4 is respectively connected to the bottom of the two baffles 21 of the battery frame assembly 2 on one side, and the other end of the two lateral stabilizer bars 4 is respectively connected to the bottom of the two baffles 21 of the battery frame assembly 2 on the other side.

[0034] The crossbeam assembly 3 is disposed between the two longitudinal beam assemblies 1, and is disposed perpendicularly to the longitudinal beam assemblies 1, with both ends of the crossbeam assembly 3 connected to the inner sides of the two longitudinal beam assemblies 1. Preferably, the two baffles 21 of the battery frame assembly 2 are disposed at positions opposite to the other side of the longitudinal beam assembly 1 relative to the crossbeam assembly 3.

[0035] In this embodiment, the batteries are symmetrically arranged on both sides of the two longitudinal beam assemblies 1 to avoid excessive concentration of battery weight.

[0036] This embodiment also incorporates a transverse stabilizer bar 4, transforming the power battery frame's cantilever beam structure into a frame structure. This enhances the battery frame's impact resistance and improves battery safety. The transverse stabilizer bar 4 also serves as a support for the high-voltage wiring harness crossbeam between the power batteries. This embodiment further reinforces the structure by incorporating a crossbeam assembly 3. The transverse stabilizer bar 4, longitudinal beam assembly 1, baffle 21, and crossbeam assembly 3 form a rigid, integrated structure, effectively increasing the rigidity and torsional strength of the vehicle frame at the power battery frame location.

After adjusting the length of the longitudinal rods 23, tighten the bolts 235 to stabilize the battery frame assembly 2.
