Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, specifically an electrical quick-change connector for a disc-shaped battery system in electric engineering machinery. Background Technology

[0002] Currently, the electrical wiring harness from the battery system to the vehicle generally consists of high-voltage power harnesses, high-voltage thermal management harnesses, and low-voltage communication harnesses. For overall vehicle stability and reliability, the wiring harnesses from the battery system to the vehicle, especially the high-voltage harnesses, employ multiple locking structures for very secure fixing. Currently, electric vehicles typically use a scheme where the high-voltage power harness, high-voltage thermal management harness, and low-voltage communication harness from the power battery are connected to the vehicle's high-voltage distribution unit (PDU), and then transferred to the vehicle control unit (VCU) and electrical appliances. In this scheme, the electrical quick-connect connector is designed between the battery pack and the vehicle's high-voltage distribution unit and vehicle control unit. Furthermore, the electrical quick-connect connectors for new energy vehicles are only compatible with passenger vehicles where a single battery pack is connected to the vehicle. However, the battery systems of electric construction machinery generally have two or three branches. Therefore, existing electrical quick-connect connectors are not suitable for the electric construction machinery field. Therefore, there is an urgent need for an electrical quick-connect connector that can be used in electric construction machinery. Utility Model Content

[0030] Example 1

[0031] See attached document Figure 1 -Appendix Figure 5 This embodiment of an electrical quick-change connector for a disc-type battery system in electric engineering machinery includes a first adapter plate 200 and a second adapter plate 300 that are configured to cooperate with each other. The first adapter plate 200 and the second adapter plate 300 are connected by a fixed shaft 100. The first adapter plate 200 has a plurality of front-end adapter interfaces, and the second adapter plate 300 has a plurality of rear-end adapter terminals. When the first adapter plate 200 and the second adapter plate 300 are in contact, the plurality of front-end adapter interfaces and the plurality of rear-end adapter terminals are correspondingly in contact and connected to conduction. This electrical quick-change connector integrates a plurality of front-end adapter interfaces into the first adapter plate 200 and integrates a plurality of rear-end adapter terminals into the second adapter plate 300. The connection and disconnection of the entire circuit can be achieved by quickly rotating and adjusting whether the first adapter plate 200 and the second adapter plate 300 are in contact. This is faster and more convenient, and multiple sets of wire harnesses can be disassembled at the same time, which can well meet the requirements of electric engineering machinery.

[0032] Several front-end adapters include front-end adapter one 210, front-end adapter two 220 and front-end adapter three 230. Front-end adapter one 210 is a high-voltage power harness front-end adapter, front-end adapter two 220 is a high-voltage heating harness front-end adapter, and front-end adapter three 230 is a low-voltage communication harness front-end adapter.

[0033] Several back-end adapter terminals include back-end adapter terminal one 310, back-end adapter terminal two 320 and back-end adapter terminal three 330. Back-end adapter terminal one 310 is a back-end adapter terminal for high-voltage power harness, back-end adapter terminal two 320 is a back-end adapter terminal for high-voltage heating harness, and back-end adapter terminal three 330 is a back-end adapter terminal for low-voltage communication harness.

[0034] The fixed shaft 100 includes a base 110, an external threaded portion 120, and a limiting post 130. The base 110 is polygonal and is adapted to the shape of the through hole of the first adapter plate 200 so that the base 110 is fixed to the first adapter plate 200. The second adapter plate 300 is provided with a threaded through hole 340. The threaded through hole 340 is configured to cooperate with the external threaded portion 120 so that the second adapter plate can rotate along the external threaded portion 120 and fit against the first adapter plate 200. The threaded through hole 340 is provided with a through hole limiting groove 350. The through hole limiting groove 350 is configured to cooperate with the limiting post 130 so that the second adapter plate 300 can pass through the limiting post 130 and contact the external threaded portion 120.

[0035] The second adapter plate 300 is provided with a handwheel assembly 360 for easy rotation, and the handwheel assembly 360 is located on the side of the second adapter plate 300 away from the first adapter plate 200.

[0036] When connection is required, the base 110 passes through the through hole of the adapter plate 200 and is fixed to the adapter plate 200. At this time, the threaded through hole 340 of the adapter plate 200 passes through the limiting post 130 and contacts the external thread 120. By rotating the handwheel assembly 360, the adapter plate 200 moves closer to the adapter plate 200 along the fixed shaft 100. The positions of the plurality of front-end adapter interfaces and the plurality of rear-end adapter terminals are set so that when the adapter plate 200 is rotated to fit with the adapter plate 200, the plurality of front-end adapter interfaces and the plurality of rear-end adapter terminals just make contact and conduct.

[0037] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
