Description

Technical Field

[0001] This utility model belongs to the field of automotive busbar technology, and in particular relates to a corrosion-resistant busbar for new energy vehicles. Background Technology

[0002] The busbar in a new energy vehicle is a key component connecting the various battery cells inside the battery pack. It is mainly responsible for current collection and distribution, ensuring the stability and safety of high current transmission. The busbar uses highly conductive materials to achieve high current transmission between the cells, ensuring the power supply required for normal charging and discharging of the battery pack. It can also be fixed to the cells through injection molding or brackets to ensure the mechanical stability of the battery pack during driving and prevent vibration from causing loose connections. However, the existing busbars in new energy vehicles are not of good enough material and have insufficient protection. Therefore, a corrosion-resistant busbar for new energy vehicles is proposed.

[0003] For example, Chinese patent CN206179539U discloses a busbar with an insulating coating for new energy vehicles, comprising a busbar body, wherein a high-temperature resistant insulating material layer is partially or entirely provided on the busbar body. This utility model's busbar can reduce costs, lighten vehicle weight, and improve energy efficiency.

[0004] The aforementioned patent has the following problems:

[0005] Compared to existing technologies, the busbar materials used in current technologies are insufficiently suitable, lacking strong protective performance and corrosion resistance. Prolonged use leads to corrosion, affecting normal operation. Furthermore, the connections in existing technologies are fixed and cannot be disassembled. When the fixing components wear out or become stripped, replacement is not possible without disassembling the entire device, increasing disassembly efficiency and delaying busbar operation. Therefore, we propose a corrosion-resistant busbar for new energy vehicles. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned technical problems by providing a corrosion-resistant busbar for new energy vehicles, achieving the effect of high-quality busbar material and the ability to remove and replace the fixing components.

[0007] In view of this, the present invention provides a corrosion-resistant busbar for new energy vehicles, including a protective box, and further comprising: a busbar body movably installed inside the protective box; an aluminum busbar layer fixedly disposed inside the busbar body; an insulating layer fixedly disposed at the bottom of the aluminum busbar layer; a copper busbar layer fixedly disposed at the bottom of the insulating layer; fixing members movably installed on both sides of the busbar body; fixing holes penetrating through the fixing members; a slot fixedly installed between the fixing members; a fixing bolt penetrating through the surface of the slot; and a sealing plate movably installed on the surface of the fixing bolt.

The aluminum busbar layer's significant oxidation resistance and corrosion resistance enhance the busbar body's service life. The copper busbar layer, with its superior conductivity and strong corrosion resistance, further enhances the busbar body's internal corrosion resistance, thus increasing its performance. The insulation layer effectively isolates the busbar from the external environment, preventing the risk of electric shock. Combined with other components, the high-quality materials and strong protective properties of the busbar body ensure corrosion resistance and long-term operation, enhancing its performance without affecting normal operation. Fasteners allow for easy installation on vehicles. The fasteners are secured to both sides of the busbar body using slots and blocks, and the blocks are then fixed to the slots using bolts. Finally, external bolts are used to secure the device to the vehicle, allowing the busbar body to operate at the work site. The connection points of the busbar body are detachable, and the fastener components are easy to replace when worn, without interrupting the busbar's operation.

[0009] Preferably, each of the inner walls of the protective box is fixedly provided with a placement block, and the surface of the placement block is provided with a filling layer, so that the placement block can easily place the busbar body.

[0010] Preferably, both ends of the busbar body are provided with through holes, a dustproof mesh is fixedly installed inside the through holes, and pure cotton layers are fixedly installed at both ends of the through holes, so that the through holes can facilitate heat dissipation.

The insulation layer can effectively isolate the busbar from the external environment and prevent the risk of electric shock. When used together, the high-quality busbar body material provides strong protection and corrosion resistance, which increases the performance of the busbar body for long-term operation without affecting normal operation.

[0017] 2. This corrosion-resistant new energy vehicle busbar can be connected to the busbar body using fasteners, making it easy to install on a vehicle.
