Rear vehicle body lower assembly

Abstract

The invention discloses a rear vehicle body lower assembly, which comprises a rear floor assembly, a rear frame assembly and a rear end plate assembly, wherein the rear floor assembly comprises a rearfloor body, a rear floor cross beam I connecting plate is fixedly connected to the front floor; the rear frame assembly comprises a rear floor cross beam I and a rear girder; the rear floor cross beam I is fixedly connected to the rear girder; the rear floor cross beam I and the rear girder are fixedly connected to the lower part of the rear floor body; a rear floor cross beam I cavity is definedby the rear floor cross beam I connecting plate, the rear floor cross beam I and the rear floor body; the length of the rear floor cross beam I cavity in the X direction is greater than or equal to 80mm; and ground sliding rail mounting points are arranged on the upper part of the rear floor cross beam I connecting plate. According to the rear vehicle body lower assembly, the X-direction rear floor cross beam I cavity is provided with the ground sliding rail mounting points in the length direction for Z-direction mounting of two rows of seat ground sliding rails, and the mounting points can be compatible with common seat guide rails.

Description

technical field [0001] The invention relates to a vehicle body technology, in particular to a rear vehicle body lower component. Background technique [0002] The existing lower parts of the rear body include the rear floor assembly, the rear end plate assembly and the rear frame assembly, and there are some deficiencies in the lower parts of the rear body: (1) the rear floor beam-01 and the rear floor beam-connection plate 02 The X-direction dimension M of the formed cavity is small (<60mm), such as figure 1 and 2 As shown, the cavity is small and can only provide ordinary guide rail installation in the X direction, and cannot provide ground guide rail installation points in the Z direction. The installation compatibility of various seats is poor, which reduces the quality and comfort of passenger cars; (2) Spare tire layout In the car, it takes up space in the trunk, and it is not convenient to load and unload the spare tire; (3) There is no battery installation point...

Problems solved by technology

[0002] The existing lower parts of the rear body include the rear floor assembly, the rear end plate assembly and the rear frame assembly, and there are some deficiencies in the lower parts of the rear body: (1) the rear floor beam-01 and the rear floor beam-connection plate 02 The X-direction dimension M of the formed cavity is small (figure 1 and 2 As shown, the cavity is small and can only provide ordinary guide rail installation in the X direction, and cannot provide ground guide rail installation points in the Z direction. The installation compatibility of various seats is poor, which reduces the quality and comfort of passenger cars; (2) Spare tire layout In the car, it takes up space in the trunk, and it is not convenient to load and unload the spare tire; (3) There is no battery installation point, and later models cannot be upgraded or equipped with a hybrid configuration. Weak competitiveness; (4) if image 3 and Figure 4 As shown, the end of the rear end plate 03 and the end of the rear frame 04 are only connected on one side, the cavity of the rear end plate and the cavity of the frame are staggered in the Z direction, the cavity is not connected, the mode of the tailgate frame is low, and the NVH noise is large
