Description

Technical Field

[0001] This invention relates to a battery pack shaping device for electric vehicles, belonging to the field of battery processing technology. Background Technology

[0002] Currently, as my country's new energy vehicle industry enters a stage of rapid, large-scale development, the safety, reliability, and range of new energy vehicle power batteries have become core concerns. The battery pack, as the load-bearing structure of the power battery, is generally installed under the vehicle body, primarily serving to protect the lithium battery from damage during external collisions or compression. However, during the production of aluminum alloy battery packs for new energy electric vehicles, slight deformations, such as edge warping and localized dents, can easily occur in the battery pack shell due to casting, welding, assembly, and demolding processes. These deformations affect the battery pack's sealing performance, assembly accuracy, and overall mechanical strength, thus impacting the vehicle's safety and lifespan. Therefore, shaping processes are typically employed during battery pack production to ensure that their dimensional accuracy meets assembly requirements.

[0047] like Figure 1-4 As shown, an electric vehicle battery pack shaping device includes:

[0048] The machine frame 1 has a receiving station and a pressing station arranged sequentially along its length.

[0049] A horizontal conveyor 2 is fixedly installed on the frame 1. The horizontal conveyor 2 is equipped with a bearing platform 20 that is suitable for reciprocating between the receiving station and the pressing station.

[0050] The column frame 3 is fixedly installed on the machine frame 1 and located at the pressing station. Multiple pressing device mounting positions are provided on the column frame 3 at intervals along the length and width directions.

[0051] The shaping mold 4 is installed on the support platform 20 and has a pre-formed groove suitable for placing the battery pack product.

[0052] The pressing device 5 is equipped with multiple pressing components. Each pressing component is installed in a corresponding position on the pressing device mounting position of the column frame 3. The pressing component is equipped with a downwardly extending telescopic end. The pressing component is adapted to drive the telescopic end to move downward to apply pressure to the battery pack product placed on the forming mold 4.

[0053] In this embodiment, as Figure 2-3 As shown, in use, the horizontal conveyor 2 first moves the carrying platform 20 to the receiving station, and the battery pack product is placed on the carrying platform 20 with the forming mold 4 fixed on it, ensuring that the battery pack product fits the pre-formed groove of the forming mold 4. Then, the horizontal conveyor 2 moves the carrying platform 20 to the pressing station. At the pressing station, the telescopic ends of multiple pressing components on the column frame 3 apply a preset pressure downwards. After a period of time, under the constraint of the forming mold 4, the deformed parts of the battery pack product gradually return to the predetermined shape, ensuring its dimensional accuracy and consistency.

[0054] In this embodiment, the battery pack product is specifically an aluminum alloy battery pack.

[0055] Specifically, such as Figure 1-4 As shown, the horizontal conveying device 2 includes:

[0056] Two linear guide rails 21 are fixedly installed on the frame 1 along the length of the frame 1.

[0057] The support slide 22 is slidably mounted on the linear guide rail 21 by a slider, and the support platform 20 is mounted on the support slide 22.

[0058] The drive roller shaft 24 is rotatably mounted on one side of the receiving station of the frame 1;

[0059] Driven wheel, the driven wheel is fixedly mounted on the transmission roller shaft 24;

[0060] Rotary drive source 27 is fixedly mounted on frame 1 and has an output shaft.

[0061] The drive wheel is mounted on the output shaft of the rotary drive source 27;

[0062] The transmission chain 29 is arranged around the driving wheel and the driven wheel, and is fixedly connected to the bearing slide 22 through a connector.

[0063] Specifically, such as Figure 2 As shown, the rotary drive source 27 is a motor.

[0064] Specifically, such as Figure 2-4 As shown, there are two linear guide rails 21, which are symmetrically arranged about the center line of the frame 1.

[0065] In this embodiment, as Figure 1-4 As shown, the horizontal conveyor 2 provides guidance and support for the carrying slide 22 via two linear guide rails 21. The power transmission structure of the horizontal conveyor 2 adopts a chain drive: the rotary drive source 27 drives the drive wheel to rotate via the output shaft, and the drive wheel is connected to the driven wheel via a transmission chain 29. The driven wheel is fixed on the transmission roller shaft 24, which is rotatably mounted on one side of the receiving station of the frame 1. The transmission chain 29 is fixedly connected to the carrying slide 22 via a connector. When the rotary drive source 27 operates, it drives the carrying slide 22 to reciprocate on the linear guide rails 21 via chain drive.

[0070] Specifically, such as Figure 1 As shown, the downward driving source 51 is a cylinder.

[0071] In this embodiment, as Figure 1-2 As shown, during operation, the cylinder's extension rod drives the pressure block 53 downwards, applying pressure to the battery pack product placed on the forming mold 4 through the pressing surface of the pressure block 53. The pressing surface and the surface shape of the forming mold 4 cooperate to constrain the battery pack product, causing its deformed parts to gradually return to the predetermined shape.

[0072] In other embodiments, the downward pressure drive source 51 may also be a linear drive device such as a hydraulic cylinder or an electric push rod. The pressing surface of the pressure block 53 can be adjusted according to the specific structural shape of the battery pack product to adapt to different models of battery pack products. In addition, the pressure block 53 may be designed to be detachable, making it easy to replace different pressure blocks 53.

[0082] Specifically, such as Figure 1 As shown, the fixing frame 34 includes an upper fixing plate and a lower fixing plate, which are respectively disposed on the upper and lower sides of the mounting beam assembly 33;

[0083] The upper and lower fixing plates are provided with corresponding through cylinder mounting holes, which constitute the mounting position of the pressing device.

[0084] The upper and lower fixing plates are also provided with corresponding connection fixing holes, and the upper and lower fixing plates are adapted to be fixedly connected by fasteners passing through the corresponding connection fixing holes of the upper and lower fixing plates.

The two frame longitudinal beams 321 and the two frame transverse beams 322 at the edge of the frame 32 form the outer perimeter, and there are three more frame longitudinal beams for reinforcement. Each set of mounting beam assembly 33 is composed of a left mounting beam and a right mounting beam arranged side by side, with a gap between the two mounting beams.

[0086] Mounting beam assembly 33 is connected and fixed to frame longitudinal beam 321 via auxiliary connecting blocks 334. Each mounting beam assembly 33 is equipped with two pairs of auxiliary connecting blocks 334, located at corresponding positions on both ends of the left and right mounting beams, respectively. The auxiliary connecting blocks 334 are positioned below the frame longitudinal beam 321 and are fixedly connected sequentially using fasteners through the first and second mounting holes. When position adjustment is required, the left and right mounting beams can be moved by loosening the fasteners and then fixed again.

[0087] The mounting bracket 34 adopts a structure combining an upper mounting plate and a lower mounting plate, which are respectively set on the upper and lower sides of the mounting beam assembly 33.
