Application: Vehicle-body front structure including reinforcement members (Patent ID: US20230264558A1)
The patent filed by Mazda Motor Corp. describes a vehicle-body front structure for an electric vehicle. The structure includes a front-side battery frame that extends in the vehicle width direction, a pair of left and right side frames that extend forward from the front-side battery frame, a cross member between the left and right side frames, and reinforcement members that extend toward the vehicle rear from the cross member towards the front-side battery frame.
The vehicle-body front structure is specifically designed for electric vehicles that have a battery casing housing a battery supplying electric power to the traveling motor, which is disposed below a floor panel. The structure includes a front-side battery frame located in front of the battery casing and extending in the vehicle width direction. It also includes a pair of left and right side frames that extend from the front-side battery frame towards the vehicle front. A cross member is positioned between the left and right side frames, spaced apart from the front-side battery frame towards the vehicle front. Additionally, there are reinforcement members that extend towards the vehicle rear from the cross member towards the front-side battery frame.
The left and right side frames are positioned on the outer sides of the vehicle in the vehicle-width-direction towards the front. The structure also includes a frame bracket that couples the rear of the left and right side frames with the front-side battery frame, with the reinforcement member abutting the frame bracket. The reinforcement member consists of a left-side reinforcement member and a right-side reinforcement member, positioned on the outer sides of the vehicle-width-direction towards the rear.
The structure further includes a suspension arm that configures a front suspension apparatus, which is supported to be swingable on the outer side of the frame bracket in the vehicle-width-direction. The front of the traveling motor is positioned in the vehicle rear of the front of the cross member. The intermediate portion of the cross member in the vehicle width direction is below the lower surface of the side frames, and the reinforcement member extends from the intermediate portion of the cross member towards the front-side battery frame below the left and right side frames.
In summary, the patent describes a vehicle-body front structure for electric vehicles that includes a front-side battery frame, side frames, a cross member, and reinforcement members. The structure is designed to accommodate the battery casing and provide support and reinforcement to the front of the vehicle.
