Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] see Figure 1 to Figure 2 , a variable-width passenger car frame connection structure, relating to a pure electric passenger car frame, capable of realizing the connection of the outer width of the front section of the frame and the middle section of the frame from narrow to wide; including the front section side beam type frame assembly 1 and the middle section truss Assembly 2. The front side beam frame assembly 1 includes a left longitudinal beam 11, a right side beam 12 and a crossbeam 13, and the outer width of the front side beam type frame assembly 1 is 710mm. The middle section truss assembly 2 includes a truss upper longitudinal beam 21, a truss lower longitudinal beam 22, a truss lower beam I23, a truss lower beam II24, a truss upper beam I25, a truss upper beam II26, and a truss upper diagonal brace whose sections a...

Abstract

Disclosed is a width-variable passenger car frame connecting structure. A front section boundary beam frame assembly (1) comprises a left longitudinal beam (11), a right longitudinal beam (12) and a transverse beam (13). A middle section truss assembly (2) comprises a truss upper longitudinal beam (21), a truss lower longitudinal beam (22), a truss lower transverse beam I (23), a truss lower transverse beam II (24), a truss upper transverse beam I (25), a truss upper transverse beam II (26), a truss upper inclined strut (27) and a truss lower inclined strut (28). The outer sides of the left longitudinal beam (11) and the right longitudinal beam (12) at the overlaid position of the front section boundary beam frame assembly (1) and the middle section truss assembly (2). Two planes of a transition connecting plate (4) are connected with the lower planes of the left and right sides of the truss upper longitudinal beam (21) and outer webs of the left longitudinal beam (11) and the right longitudinal beam (12). Transition of the frame with the narrow front part and the wide rear part is achieved, and the strength of the connecting portion is effectively ensured.

Description

technical field [0001] The invention relates to a vehicle frame connection structure, more specifically to a vehicle frame connection structure with variable width, and belongs to the technical field of passenger vehicles. Background technique [0002] The frame structure of a pure electric bus is usually a three-section overlapping frame structure: the front and rear sections are side beam frame structures, the middle section is a truss frame structure, and the middle section is used to arrange batteries. At the joints between the front frame assembly and the middle truss assembly, and between the middle truss assembly and the rear frame assembly, the length of the upper longitudinal beam of the middle truss is usually extended so that the lower plane of the upper longitudinal beam of the middle truss is fixed on the front and rear sides through vertical beams. On the upper wing surface of the frame longitudinal beam; at the same time, at the overlap between the upper longi...
