[0002] As a crucial load-bearing component of a car, the structural stability and assembly efficiency of the car frame directly affect the car's performance and production efficiency.

[0003] For example, Chinese patent application number 202022781020.0 discloses an automotive frame assembly, characterized by comprising a front longitudinal beam assembly, a floor longitudinal beam assembly, and a rear longitudinal beam assembly connected sequentially from front to rear. The front and rear longitudinal beam assemblies are at the same height, and the floor longitudinal beam assembly is lower than the front and rear longitudinal beam assemblies, creating a battery storage space above the floor longitudinal beam assembly. All three assemblies are made of aluminum alloy. This automotive frame has advantages such as a reasonable structural design, low weight, and the ability to increase battery capacity without increasing the overall vehicle weight, thus improving vehicle range.

[0004] However, during the assembly of this car frame, the positioning accuracy of the longitudinal and transverse beams is relatively low, often requiring the use of complex tooling fixtures for auxiliary positioning. This not only increases the cost of production equipment but also prolongs the assembly time. Furthermore, during welding, inaccurate positioning can easily lead to welding deviations, affecting the structural strength of the frame, increasing welding difficulty and subsequent correction work, and hindering the improvement of production efficiency and the assurance of product quality.

[0018] In this embodiment, multiple reinforcing ribs 102 are fixedly sleeved on the two longitudinal beam rods 101 from one end to the other. A baffle 104 is fixedly installed on both sides of the two first docking positioning grooves 103 on the top surface of the longitudinal beam rod 101 and located on the same side. A locking block 105 is fixedly installed between the two first docking positioning grooves 103 on the same side. The reinforcing ribs 102 can effectively enhance the bending and deformation resistance of the longitudinal beam rod 101 and ensure the structural stability of the longitudinal beam assembly 1.

[0019] Meanwhile, a second locking block 109 and a second baffle 110 are fixedly installed on the top surface of the longitudinal beam 101 and on both sides of the second docking positioning groove 108.
