Problems solved by technology

However, in order to meet the requirements of the collision test on the side of the deformable mobile barrier, the traditional non-load-bearing SUV needs to increase the requirements of the body parts such as the body B-pillar, body floor and side wall for the amount of collision energ

Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the embodiments and with reference to the accompanying drawings.

[0013] A side impact limiting device for an SUV frame, comprising a frame longitudinal beam 5 located below a vehicle body floor 8 and a vehicle body B-pillar 6 located between the front door 1 and the rear door 3 of the vehicle body, fixed and perpendicular to the frame longitudinal beam 5, On the outer wall of the vehicle frame longitudinal beam 5 in front of the B-pillar 6 of the vehicle body, directly below the driver's seat 2, and near the R point 4, there are fixed top plate 10, left side plate 9, bottom plate 12, right side plate 13 and outer plate 11. A steel side impact limit box 7 is formed to improve the rigidity of the side impact limit box.

[0014] The distance L between the outer panel 11 of the side impact limiting box 7 and the inner wall of the front door 1 of the vehicle body is 50--58mm.

Abstract

The invention discloses a frame side-impact limiting device for SUVs (sport utility vehicles), which comprises a frame longitudinal beam and a body B pillar. The limiting device disclosed by the invention is characterized in that a steel side-impact limiting box consisting of a top plate, a left side plate, a bottom plate, a right side plate and an outer plate is fixed on the external sidewall ofthe frame longitudinal beam in front of the body B pillar, under a driver seat, and at a position close to a point R so as to improve the rigidity of the side-impact limiting box. The side-impact limiting box can participate in the absorption of impact energies during the early and middle periods of impact, thereby reducing the requirements on the quantity of absorbed impact energies of body parts such as the body B pillar, a body floor and a side body, and the like, namely, correspondingly reducing the rigidity demands for the body parts, reducing the complexity of the body structure, and lowering the process requirements of the body. By using the side-impact limiting device disclosed by the invention, when a side impact occurs to vehicles, impact energies can be transferred to the framelongitudinal beam as many as possible and then absorbed efficiently so as to reduce the damages to a body passenger cabin; and the side-impact limiting device has the advantages of less investment and low cost, therefore, the side-impact limiting device is suitable for non-stressed SUVs.

Description

technical field [0001] The invention relates to automobile equipment, in particular to a side impact limiting device for an SUV vehicle frame. Background technique [0002] With the development of international and domestic automobile technology, people pay more and more attention to the passive safety of automobiles, and the new car crash test (NCAP) test has become an important indicator to measure the advancement of vehicle technology, and side collision is one of them. There are three main test methods (a total of three collision methods: 1. Frontal 40% overlapping deformable barrier impact test; 2. Deformable mobile barrier side impact test; 3. Frontal 100% overlapping rigid barrier impact test). For a non-load-bearing SUV (sports utility vehicle), the protection measures for the occupant compartment during side collisions are mainly the pillars between the front door and the rear door of the body (that is, the B-pillar of the body), the strength of the side wall of the...
