Description
Technical field
The utility model relates to a kind of automobile four people's seat cushion frame structures that improve automotive seat impact strength.
Background technology
Existing automobile four people's seat seat skeletons adopt traditional frame tubular structure, and each seat is equipped with 1 two-point belt.Well-known: safety strap is arranged on seat back conventionally, so, when stressed, the suffered power of rear row's attachment point is greater than the suffered power of front-seat attachment point.Later row's attachment point is example, and the leftmost side and rightmost side attachment point institute is stressed is the component of a safety strap, establishes it for F, so 3 the stressed 2F that just should be of attachment point in centre.And in fact, because being limited to body structure, under the seat of the leftmost side, do not allow supporting leg to exist, the namely attachment point of leftmost side disappearance.Second the suffered power of attachment point in left side is exactly that 3F adds a moment M=F*L so, much larger than former numerical value.And attachment point does not drop on supporting leg, but there is certain distance.Make seat, left side skeleton holding capacity for maximum.And safety strap can form rotation under external force, is unfavorable for safety.
The seat of traditional automotive seat and backrest connection mode generally adopt the connection mode of playing bolt on connecting panel, this cannot ensure personal safety under seat GB13057 impact test requires, because seat and backrest junction are the main stress point of seat, and can first there is modification in connecting panel under external force, fracture.
Existing seat design generally adopts solid circular pipe to play the effect that seat is strengthened, and this has a larger requirement to seat mould and material cost.Car load seat-weight increases to some extent, is not suitable for the seat weight-saving designing requirement that client proposes.Safety strap and mortise lock often rotate the safety that is unfavorable for human body.
Summary of the invention
In order to overcome the above problems, the utility model provides a kind of automobile four people's seat cushion frame structures that improve automobile chair frame impact resistance.
The unit design of seat not merely will be considered belt anchorage point test, also will consider backrest strength test.In other words in the time that back of seat is subject to rear impact, power finally can pass on seat skeleton.Skeleton is often out of shape seriously, and seat is also comparatively serious by connecting panel distortion, shows He Zuokao junction, rear end insufficient rigidity, and cushion frame intensity cannot meet the requirement of experiment.This has brought great difficulty with regard to the design of giving cushion frame.
The utility model is through contriver's performing creative labour, adopt topological optimization, by preliminary cae analysis, find out the weak link of skeleton, determine rational frame mode according to known boundary condition with carrying with condition, proposed brand-new automobile four people's seat cushion frame structures.
The technical solution adopted in the utility model is: automobile four people's seat cushion frame structures, comprise four people's cushion frames, four people's backrest frames and safety strap, and framework and straight tube form the basis of cushion frame, and connecting panel links together cushion frame and backrest frames; The bolt hole I being connected with cushion frame on connecting panel is made ellipse, the two ends of four U-shaped frame pipes are individually fixed on the framework and straight tube at 3 cushion frame places, two diagonal ligament beam symmetries are installed on the 4th cushion frame lower end of end, one end and the welding of frame pipe, the other end and the U-shaped frame pipe welding closing on.
Above-mentioned automobile four people's seat cushion frame structures, are provided with three blanked parts, and a blanked part is installed on diagonal ligament beam and U-shaped frame pipe weld, and another 2 blanked parts are installed on the U-shaped frame pipe place between first and second seats.
Above-mentioned automobile four people's seat cushion frame structures, safety strap installation place is provided with limiting stopper.
Above-mentioned automobile four people's seat cushion frame structures, are provided with left and right seat by connecting backplate in junction, two seats.The bolt hole II that left and right seat is connected with cushion frame by connection backplate is made ellipse.
The beneficial effects of the utility model are: 1. designed two diagonal ligament beams and be welded on upper box pipe and U-shaped frame pipe, utilized leg-of-mutton stability, made skeleton when stressed, the distortion of upper box pipe is less, and straight tube and U-shaped pipe deflection are less.There is enough rigidity, make the strain energy minimum (rigidity maximum) of seat.U-shaped framework is subject to the tensile force of directions X, the U-shaped framework directions X energy distribution percentum proportion of four limit types can be larger, easily distortion, having designed one end is diagonal ligament girder construction, make bearing surface be converted into by four limit types the triangular form that crossbeam and support beam form, the seat collision and the safety strap tensile energy that have absorbed directions X, the stability of seat is enhanced.2. on supporting leg, be welded with a blanked part, attachment point is positioned on blanked part, in the time bearing forward direction load, resist the ability of torsional deflection to improve seat.Blanked part has sufficient intensity, in the time that collision stretches, and the absorption energy that first deforms of the blanked part on arm, then be transmitted on arm, play the effect of buffering.3. between blanked part, reserve space between blanked part and U-shaped framework, when stressed, can, by the distortion of blanked part, absorb energy like this, avoid because rigidity is excessive, solder joint being torn.4. the bolt hole being connected with cushion frame on connecting panel is designed to slotted eye, makes backrest in the time being subject to clashing into, play buffer action, reduces to greatest extent impulsive force.5. middle part increases left and right seat and increases resistance type intensity by connecting backplate.6. safety strap junction is installed and breaks original design idea and on connecting panel, increase limiting stopper, prevent safety strap rotation.
