Embodiment Construction

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings. In the subsequent descriptions, the terms "upper", "rearward", and "right" are used figure 1 described as a benchmark.

[0044] Such as figure 1 The passenger compartment shape-retaining device shown comprises a dash panel 3 , a dashboard cross member 2 and an additional support beam 1 extending between the dashboard cross member 2 and the dash panel 3 . Such as figure 2 As shown, the instrument panel beam 2 has opposite first end portions 201 and second end portions 202, and a center point located at the midpoint between the first end portion 201 and the second end portion 202. 203. There is a steering column mounting bracket 4 on the instrument panel crossbeam 2, for simplicity of illustration, in figure 1 The steering column mounting bracket is...

Abstract

The invention discloses a passenger compartment shape retention device and an automobile provided with the same, relates to a passenger compartment shape retention device for protecting safety of passengers during collision of an automobile, and belongs to the field of safety devices of automobiles. The passenger compartment shape retention device comprises a front wall plate, an instrument board crossbeam and an additional support beam extending between the front wall plate and the instrument board crossbeam, and a joint of the additional support beam on the instrument board crossbeam is positioned between a steering column mounting support and a second end. The passenger compartment shape retention device is simple in structure, the additional support beam is connected with the instrument board crossbeam and the front wall plate, deformation of the additional support beam, the instrument board crossbeam and the front wall plate which are used as a combination during collision is controllable, and the additional support beam cannot be broken to cause excessively high maintenance expenditure. Besides, the additional support beam is arranged between the instrument board crossbeam and the front wall plate, and the integral collision resistance of the passenger compartment shape retention device is improved, so that rearward movement of the instrument board crossbeam and rearward movement of the front wall plate are effectively controlled, and injury to chests of passengers is relieved.

Description

technical field [0001] The invention relates to a passenger compartment shape maintaining device for protecting occupants in automobile collision, and belongs to the field of automobile safety devices. Background technique [0002] In the event of a car collision, usually, the stiffness of the passenger compartment is directly related to the injury of the occupants (driver and passenger). The greater the stiffness of the passenger compartment, the smaller the deformation of the cabin during the collision, so that the living space of the occupants is guaranteed. , the occupant's injury will be reduced accordingly, and the safety performance of the car is just relatively high. Therefore, in consideration of safety, the passenger compartment must have sufficient rigidity to resist deformation. [0003] The passenger compartment is composed of the front door, A-pillar, dash panel, door sill, roof and B-pillar. These key components must have sufficient rigidity to support the de...
