Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a highly stable left front floor crossbeam for automobiles. Background Technology

[0002] The left front floor crossbeam is an important structural component of the front of a car body. Located in the left front floor area, it mainly serves to support, connect, and transfer loads, providing structural strength to this area and ensuring the stability of the left front floor section during vehicle operation. It can also adapt to and connect surrounding body components such as the floor and longitudinal beams, making it one of the key components for maintaining the structural integrity and performance of the front of the vehicle body.

[0003] Despite the many advantages of the left front floor crossbeam of a car, there are still some areas for improvement. For example, when subjected to complex and high-frequency vibration and impact loads over a long period of time, if the environment is harsh, the connection between the crossbeam and adjacent components may have some room for improvement in durability due to continuous stress. However, overall it can still meet the needs of normal use quite well. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 As shown, a highly stable left front floor crossbeam for automobiles includes a main body 1 and auxiliary structural components 2, and further includes: The bent portion 3 is set on the main body 1 of the floor beam. The main body 1 of the floor beam and the auxiliary structural component 2 are engaged and fixed together. The auxiliary structural component 2 is a stamped support plate 4. Through the bent portion 3 on the main body 1 of the floor beam and the support plate 4, the product shape can be precisely adapted to other components in the left front floor area of ​​the vehicle to form a stable floor frame structure. Through the main body 1 of the floor beam and the support plate 4, the connection is strengthened and adapted to other body components such as the floor and longitudinal beams, or it plays a role in positioning and auxiliary fixing during assembly. Through cooperation with the main structure, the structural stability and assembly rationality of the left front floor beam and even the entire front of the vehicle are improved.

[0015] The floor beam body 1 and the support plate 4 are made of DC03 material, and both are 2mm thick. The floor beam body 1 is formed by stamping, trimming and cutting and welding. The bending part 3 is formed by stamping and welding. The floor beam body 1 and the support plate 4 are made of DC03 material with a plate thickness of 2mm. The plate is cut, stamped, trimmed and cut and welded. The material has good plasticity and ductility, and is suitable for processing into complex shapes by stamping process. It can meet the certain requirements of automotive parts for formability and strength.

[0016] The bottom of the floor beam body 1 is convex. Two reinforcing ribs 5 are welded to one side of the bend of the floor beam body 1. A locking pin 6 is fixedly connected to one side of the support plate 4, and a reinforcing rib 7 is welded to one side of the support plate 4. The convex bottom of the floor beam body 1 facilitates the installation and fixation of vehicle body parts. The reinforcing ribs 5 can improve the structural strength of the floor beam body 1 itself. The locking pin 6 facilitates the auxiliary fixation of the floor beam body 1 and the support plate 4. The reinforcing ribs 7 on the support plate 4 can improve the overall strength of the support plate 4 and ensure the stability of long-term use.

[0017] Working Principle: The reinforcing ribs 5 on the main body 1 of the floor beam and the reinforcing ribs 7 on the support plate 4 simultaneously enhance their strength. The product is made of DC03 material with a thickness of 2mm. The material has good plasticity and ductility, making it suitable for processing into complex shapes through stamping. It can meet the certain requirements of automotive parts for formability and strength. Furthermore, the main body 1 of the floor beam has concave and convex treatments, and the product shape can be precisely adapted to other components in the left front floor area of ​​the vehicle to form a stable floor frame structure. This effectively disperses the forces from above the vehicle, such as the weight of passengers and cargo, and from below, such as road impacts. It can better connect with adjacent longitudinal beams, pillars, and other components, enhancing the integrity and stability of the vehicle's bottom structure. As an important component of the vehicle floor structure, the main body 1 of the left front floor beam bears part of the load from above the vehicle, including the weight of passengers and the weight of cargo placed inside the vehicle. It evenly transfers these loads to other supporting components of the vehicle body, such as longitudinal beams and pillars, preventing excessive local stress on the floor and causing deformation or damage, thus ensuring the stability and safety of the vehicle during driving.
