Problems solved by technology

[0004] In the process of realizing the present invention, the inventor has found that the prior art has at least the following problems: the existing A-pillar pair is not enough to improve the torsional bending rigidity of the vehicle body, especially the A-pillar pair of a movable roof car does not have a traditional car upper closed structure band for offsetting. The effect of the reduced stiffness is not obvious, which makes the safety performance of the car not high

Embodiment 1

[0022] This embodiment provides an A-pillar of a movable roof automobile, see figure 1 , the A-pillar of the movable roof car includes: A-pillar outer panel assembly 1 and A-pillar inner panel assembly 2, A-pillar outer panel assembly 1 and A-pillar inner panel assembly 2 have a structure that is close to each other and strengthens each other. The A-pillar outer panel assembly 1 and the A-pillar inner panel assembly 2 are fixedly connected by welding to form an A-pillar assembly structure with greatly improved rigidity and strength. As other embodiments, the A-pillar outer panel assembly 1 and the A-pillar inner panel assembly 2 may also be fixedly connected by means of bolt connection, snap-in connection, continuous laser welding or structural adhesive connection.

[0023] A-pillar outer panel assembly 1 includes side wall outer panel 11, A-pillar lower reinforcement panel 12, A-pillar upper reinforcement panel 13 and A-pillar outer panel 14, side wall outer panel 11, A-pilla...

Embodiment 2

[0026] This embodiment provides an A-pillar of a movable roof automobile, see figure 1, the A-pillar of the convertible roof automobile includes an A-pillar outer panel assembly 1 and an A-pillar inner panel assembly 2, and the respective structures, assembling and connection relations of the A-pillar outer panel assembly 1 and the A-pillar inner panel assembly 2 are the same as in Embodiment 1 Similarly, the A-pillar of this embodiment also includes a reinforcing round tube 3, and the reinforcing round tube 3 is fixed between the A-pillar outer panel assembly 1 and the A-pillar inner panel assembly 2, and is connected with the A-pillar outer panel assembly 1 and the A-pillar The inner panel assemblies 2 are all welded or riveted or bolted. The reinforcing round tube 3 is processed into a folded shape, that is, the reinforcing round tube 3 includes a first section fixedly connected with the A-pillar lower reinforcement plate 12 and a second section fixedly connected with the A...

Embodiment 3

[0029] This embodiment provides an A-pillar of a movable roof automobile, see figure 1 , the A-pillar of the convertible roof car includes the A-pillar outer panel assembly 1, the A-pillar inner panel assembly 2 and the reinforced round tube 3, the A-pillar outer panel assembly 1, the A-pillar inner panel assembly 2 and the reinforced round tube 3 respectively The structure and assembly connection relationship are the same as in the second embodiment. The A-pillar outer panel assembly 1 of the A-pillar in this embodiment also includes a threshold front reinforcement plate 15 and a threshold rear reinforcement plate 16, and the threshold front reinforcement plate 15 and the threshold rear reinforcement plate 16 are welded to the side wall outer panel 11 and under the A-pillar for reinforcement. plate 12. In this way, the strength of the root of the A-pillar and the bearing capacity of the entire lower part of the A-pillar are greatly improved. As other embodiments, the front ...

Abstract

The invention discloses a column A of an automobile with a movable roof. The column A comprises a column A outer-plate assembly (1) and a column A inner-plate assembly (2), wherein the column A outer-plate assembly (1) comprises a side outer plate (11), a column A lower reinforced plate (12), a column A upper reinforced plate (13) and a column A outer plate (14), which are fixedly connected together; the column A inner-plate assembly (2) comprises a front vertical plate body (21) and a column A inner plate (22), which are fixedly connected together, and the column A belongs to the field of an automobile body structure. The invention also provides the automobile with the movable roof. The automobile comprises the column A. The automobile can play good reinforcing and protecting roles by additionally arranging a reinforced round tube between the column A outer-plate assembly and the column A inner-plate assembly, so the automobile body structure is stable and reliable. Through a high-strength material adopted by parts on the column A inner-plate assembly structure, deformation in collision can be effectively resisted, so that the automobile can provide a enough passenger survival space during reversing.

Description

technical field [0001] The invention relates to the field of automobile body structures, in particular to an A-pillar of a movable roof automobile. The invention also relates to a convertible roof vehicle comprising said A-pillar. Background technique [0002] The A-pillar on a car is the support structure between the front engine compartment and the front doors. When designing the A-pillar, the angle at which it blocks the driver's line of sight must be considered. Generally, the binocular overlap angle of the driver's line of sight through the A-pillar is 5 to 6 degrees in total. The ideal situation is that the binocular overlap The smaller the angle, the better, but the design of the A-pillar must have a certain geometric size to maintain the rigidity of the body and the ability to transmit and bear loads during a collision. [0003] For the coupe with a movable roof, since there is no protection of the closed frame structure of the upper part of the traditional car bod...
