Abstract
The utility model discloses a kind of motor vehicle seat cross-member structure, and comprise the cross-beam body of cross section in " several " shape, described cross-beam body is provided with to " several " shape inner recess and runs through the strengthening groove of whole cross-beam body.The utility model increases its cross section power of bearing when not increasing part and cost, thus reach reduce its distortion, optimize crew module collide effect.
Description
Technical field
The utility model relates to vehicle seat component, particularly relates to a kind of seat beam structure that can improve impact resistant capability.
Background technology
Along with the fast development of auto-domain, domestic and international regulation, new car evaluation criterion and the requirement of customer to automotive safety are also more and more higher.Collision performance is an important indicator of automotive safety factor, and therefore relevant to collision structure also becomes during body structure designs is worth one of pith studied.For crash feature, our emphasis has hard and soft two parts in the design, and firm part is in structure design, have enough intensity, ensures that crew module is out of shape minimum; Soft part is in structure design, has certain distortion energy-absorbing space, reduces the collision energy being directly delivered to crew module.
Seat beam is as the parts connecting threshold and middle passage, one of important power transmission and load parts in collision (especially side impact and post touch), the structure design of seat beam, determines the member cabin distortion in collision and energy-absorbing effect to a great extent.Seat beam design common at present, principal mode is " several " font, side impact is under especially post touches condition, because seat beam stage casing opposite end is without strengthening measure, namely this region relative rigidity is poor, easily there is moderate finite deformation even bending in this region, cause intrusion volume to increase, make to rise to the injury values of occupant.
Utility model content
Technical problem to be solved in the utility model realizes the good seat beam structure of a kind of side impact performance.
To achieve these goals, the technical solution adopted in the utility model is: a kind of motor vehicle seat cross-member structure, comprise the cross-beam body of cross section in " several " shape, described cross-beam body is provided with to " several " shape inner recess and runs through the strengthening groove of whole cross-beam body.
Described strengthening groove is provided with multiple knock hole for welding location.
The height of described strengthening groove is the 1/5-1/3 of " several " shape cross-beam body height.
Described cross-beam body one end is fixed with the outer mounting bracket of seat, and the other end is fixed with mounting bracket in seat.
The utility model increases its cross section power of bearing when not increasing part and cost, thus reach reduce its distortion, optimize crew module collide effect.
Accompanying drawing explanation
Mark in the content expressed every width accompanying drawing in the utility model specification sheets below and figure is briefly described:
Fig. 1 is seat beam structural representation;
Fig. 2 is A-A schematic cross-section in Fig. 1;
Fig. 3 is seat beam using state schematic diagram;
Mark in above-mentioned figure is: 1, cross-beam body; 2, strengthening groove; 3, the outer mounting bracket of seat; 4, mounting bracket in seat; 5, knock hole.
Detailed description of the invention
As shown in Figure 1, 2, cross-beam body 1 is list structure, and cross section is in " several " shape, and cross section, left and right is consistent substantially, and side is connected with threshold, side and middle expanding channels.Cross-beam body 1 can adopt the steel plate of more high strength, as HC420/780DP etc., so can further improve the performance of seat beam.Have through groove at the medium design of crossbeam, i.e. strengthening groove 2, strengthening groove 2 is to " several " shape inner recess.Sunk structure improves the object of seat beam rigidity and cross section power; collision intrusion volume is reduced better to protect occupant, because cross-beam body 1 has strengthening groove 2, employing high strength steel plate can be coordinated; the material reducing seat beam is thick, with the object reaching loss of weight He reduce costs.This depth of groove and width can according to technique and the settings of cae analysis result, and preferred parameter is the height of strengthening groove 2 is " several " shape cross-beam body 1 1/5-1/3 highly.
Strengthening groove 2 is provided with multiple knock hole 5 for welding location, like this when welding, the position of cross-beam body 1 can be determined, convenient for assembly, as shown in Figure 3, actual center member body 1 two ends that use are respectively equipped with mounting bracket 4 in the outer mounting bracket 3 of seat and seat, and cross-beam body 1 is welded as seat beam assembly with mounting bracket 4 in the outer mounting bracket 3 of seat, seat.
