Embodiment 1

[0043] The specific implementation of this embodiment is as follows:

[0044] Such as figure 1 As shown in -8, the passenger car rear row anti-submersion device and related components are provided for this embodiment. The passenger car rear row anti-submergence device includes a buffer block 300 and clamping mechanisms arranged on both sides of the buffer block 300 , the clamping mechanism and the buffer block 300 can be detachably installed on a flat plate; the clamping mechanism includes a front clamping structure and a rear clamping structure, the front clamping structure is used to prevent the buffer block 300 from moving forward, and the rear The clamping structure is used to squeeze the buffer block 300, and the buffer block 300 collapses and deforms under the action of the front clamping structure and the rear clamping structure, forming a constant collapse force.

[0045] It should be noted that the rear clamping structure of this embodiment will be detached from the ...

Embodiment 2

[0067] The passenger car provided in this embodiment is provided with the rear submersible device of the first embodiment above, and the mounting plate 100 is fixedly connected to the floor under the rear seats of the passenger car.

[0068] It should be pointed out that the mounting plate 100 is connected to the floor under the rear seats of the passenger car by welding.

[0069] The passenger car of this embodiment solves the problem that the current anti-submersion device or the restraint process is uncontrollable or the occupant's waist is likely to be injured due to excessive rigidity.

Abstract

The invention provides a passenger vehicle back row descending prevention device, and relates to the technical field of vehicle body structures. The passenger vehicle back row descending prevention device comprises a buffer block and clamping mechanisms arranged on two sides of the buffer block, and the clamping mechanisms can be detachably mounted on a flat plate when being stressed to a certaindegree. The clamping mechanisms comprise front clamping structures and rear clamping structures, wherein the front clamping structures are used for stopping the buffer block from moving forward, and the rear clamping structures are used for squeezing the buffer block. The buffer block is collapsed to deform under the action of the front clamping structures and the rear clamping structures to formconstant collapsing force. A passenger vehicle comprises the passenger vehicle back row descending prevention device. By the aid of the technical scheme, the problem of easiness in injury to the waistof a passenger due to uncontrollability or excessive stiffness of a current descending prevention device or constraint process is solved.

Description

technical field [0001] The invention relates to the technical field of vehicle body structures, in particular to a passenger car rear row anti-submersion device and a passenger car. Background technique [0002] At present, during a frontal collision of a passenger car, the rear occupants usually dive. Therefore, the passenger car should be designed to prevent submersion during the design process. [0003] The existing anti-submersion design is basically divided into two situations. One is to design the body structure under the rear seats to be high at the front and low at the rear; dive gear. Among the two designs, the main design is to increase the anti-submersion device, and the current anti-submersion device is usually a frame structure that is folded into a "J" shape with a thin steel plate. [0004] At present, the anti-submersion device for the rear row of a passenger car as a frame structure, when the structural rigidity is insufficient, often bends and collapses s...
