Description

Technical Field

[0001] The utility model relates to the technical field of wiring harness systems for new energy electric vehicles, in particular to a foldable and extendable wire protection box. Background Art

[0002] A foldable and extendable cable protection box refers to a device that can be folded to save space when not in use, and unfolded when needed to provide cable protection and management. This type of cable protection box is usually made of flexible but strong materials, allowing it to be freely adjusted between different lengths and shapes. It is designed for easy storage and carrying. At the same time, in actual use, it can effectively protect wires and cables from external damage, avoid entanglement and mess. Foldable and extendable cable protection boxes are very practical in the wiring harness system of new energy electric vehicles, helping to keep the cables in the wiring harness system of new energy electric vehicles neat and orderly, and reducing potential safety hazards. In the development and production process of new energy vehicles, the wiring harness system of the battery pack faces many technical challenges. In particular, since vehicles with different types of configurations require battery packs of different sizes and structures, this puts higher requirements on the protection and management of the wiring harness.

[0003] Traditional wire harness protection measures are often difficult to adapt to diverse battery pack structures and have the following problems: First, traditional wire harness protection devices are usually designed according to specific battery packs, lack flexibility, and are difficult to adapt to battery packs of different sizes and shapes. This results in the need to develop wire harness protection components separately for each vehicle model, increasing development time and cost; second, after the battery pack and wiring harness are installed as one, especially the wiring harness at the front panel is prone to bumps and damage during transportation. Existing protection measures cannot effectively protect these wiring harnesses, leading to potential safety hazards and maintenance costs; third, due to the diversity of battery pack structures of different models, wire harness protection parts are difficult to use universally. This situation not only increases the R&D and procurement costs of parts, but also extends the development cycle of the entire vehicle, affecting the rapid launch of new models.

[0004] Based on this, we propose a foldable and extendable wire protection box to solve the above-mentioned problems. Utility Model Content
