Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and more specifically, to a vehicle front structure and a vehicle. Background Technology

[0002] In the field of vehicle design and manufacturing, the strength and rigidity of the vehicle body structure are crucial to vehicle performance and safety, and consumers have increasingly higher demands for vehicle performance, safety, and comfort. Against this backdrop, the design of the vehicle's front structure has become a focal point in the automotive industry.

[0003] Currently, in the design and manufacturing process of many vehicles, the front bulkhead structure is an important component of the front of the vehicle body, especially the front bulkhead panel. The front bulkhead panel needs to withstand forces from multiple directions, including supporting the upper drainage channel, which is an important channel to guide water away from the interior of the vehicle body during rain or washing. At the same time, the front bulkhead panel is also responsible for fixing and supporting the brake pedal assembly, which is the direct interface for the driver to control the vehicle's braking system.

[0004] However, some current designs fail to adequately consider the strength and rigidity requirements of the front bulkhead structure. The front bulkhead is often relatively thin, making it difficult to meet the rigidity requirements of both the front bulkhead and the brake pedal, directly impacting the overall performance of the vehicle. Specifically, the following issues arise: First, the brake pedal is mounted on the front bulkhead via a brake pedal mounting plate, affecting the structural stability of the brake pedal and reducing braking efficiency. This leads to inaccurate driver braking commands, further impacting braking effectiveness. Second, the front bulkhead is prone to deformation under impact or braking force, affecting not only the overall rigidity of the vehicle body but also potentially its safety performance. Third, insufficient rigidity in the front bulkhead structure leads to decreased NVH performance, causing additional vibration and noise during driving, severely affecting ride comfort and driving experience.

[0005] Therefore, in order to address the shortcomings of existing vehicle front bulkheads, there is an urgent need to develop a new structure to improve the overall rigidity of the vehicle front bulkhead structure, ensure the stability and sensitivity of the brake pedal, and improve the NVH performance of the vehicle to meet the requirements of high performance, safety and comfort.
