Predetermined deformation position can be realized by telescopic connecting device.At this, the lower wall panels area part of air guide member is contained in the wainscot region of air guide member.Wainscot region and lower wall panels region are interconnected by attaching parts.When the collision energy that may be caused by accident is elevated to certain level, then attaching parts lost efficacy and up and down panel region can be moved in opposite directions.Level of force and the energy absorption of connecting device can be set as required by the respective design (wall strength of attaching parts also can be locally weakened) of attaching parts.
But it is difficult that this set is proved to be in manufacturing technology.The suitable setting of ceiling capacity absorptive character or power threshold values (being wherein provided with attaching parts) is both also relevant with the geometric tolerances of attaching parts to the mechanical specialities of used material.The mechanical specialities of predetermined breaking part also may cause change undesirable and more rambunctious due to the ageing process of used plastic material and contraction process and temperature impact.
Arrange predetermined breaking part by the telescopic connection of upper and lower panel region to also determine, attaching parts extends in the whole length of panel region.If such as only local and occur the mechanical load of the loadlimit close to attaching parts on a position of attaching parts, then this may cause in the whole length of attaching parts, producing the diverse deformation characteristic in local, until cause the distortion of the alternate sides of upper and lower panel region.
Utility model content
Technical problem to be solved in the utility model is, provide by a kind of instrument carrier panel for being placed in the main cabin of self-propelled vehicle or the air flue of below, it has reproducible deformation characteristic and collision characteristic to a great extent.In addition, the deformation characteristic of air flue and collision characteristic should only be affected by inevitable production tolerance and/or build-up tolerance as small as possible.In addition, air flue should manufacture especially economically and manufacture at low cost.
Described technical matters is solved according to self-propelled vehicle of the present utility model by one, described self-propelled vehicle has main cabin and settles instrument carrier panel within it and air flue, described air flue is placed in described instrument carrier panel side or below, and have can ventilate and by around the flow cross section of conduit wall limited boundary, wherein, described conduit wall has towards the upper wall section of described instrument carrier panel and the lower wall section opposite with described upper wall section, wherein, the side wall sections that described upper wall section and lower wall section are vertically extended along vehicle-height direction by least one is interconnected, described side wall sections has at least one crooked position, imaginary line between the upper end of described crooked position and described side wall sections and bottom separately, and wherein, when pointed to straight down and size exceedes the effect of the power of pre-set threshold value time, described side wall sections is collapsed in the mode set by described crooked position.
At this point, self-propelled vehicle has main cabin and the instrument carrier panel be placed in main cabin and air flue, and described air flue is placed in by the instrument carrier panel in described main cabin or below.Described air flue have can ventilating air and by around the flow cross section of conduit wall limited boundary.Described conduit wall has multiple wall section.So-called upper wall section at this usually, namely under the installing condition of air flue towards the instrument carrier panel extended above air flue.On the opposite of the upper wall section towards instrument carrier panel, the conduit wall of air flue has lower wall section.Upper wall section and the lower wall section of the conduit wall of air flue are interconnected by least one side wall sections.Side wall sections extends along vehicle-height direction vertically at this, and that is, the extension of side wall sections has at least one vertical portion section along vehicle-height direction.Thus, the side wall sections angle that at least local is less than 90 ° with relative vehicle height axis extends.
Described side wall sections has crooked position, and the imaginary line between the upper end of described crooked position and side wall sections and bottom separately.Line extends point-blank between the upper end and bottom of side wall sections.The upper end of side wall sections is connected with upper wall section, and the bottom of side wall sections is connected with the lower wall section of conduit wall simultaneously.
Side wall sections also has default deformation characteristic and characteristic of collapsing.Thus, when pointed to straight down and size exceedes the effect of the power of pre-set threshold value time, side wall sections is collapsed in the mode set by crooked position.The vertical power that can import by instrument carrier panel higher than threshold value causes the distortion of side wall sections and whole passage or collapses, this threshold values is relevant to the material behavior of the geometric configuration of crooked position, the geometric configuration of side wall sections and orientation and air flue, and can correspondingly change.
Due to run-off the straight when air flue is especially collapsed at the application force pointed to straight down, make under collision situation, to desirably reduce air flue to the space requirement in vehicle-height direction.Instrument carrier panel can there is vibration damping at this point with absorb collision, the skew pointed to straight down moves.
When at least one be integrated in the crooked position in side wall sections keep interval relative to the imaginary line between the upper end of side wall sections and bottom time, side wall sections has that at least one imaginary rectilinear outline from side wall sections inwardly or outwards offsets, retraction or outstanding crooked position thus, and this crooked position imparts side wall sections and the curved characteristic thus required for whole conduit wall and deformation characteristic.
Curved characteristic, deformation characteristic or the characteristic of collapsing of side wall sections or whole air flue especially can be controlled by means of only the moulding of crooked position or by the geometry trend of crooked position and are on purpose changed.At this point, air flue also can independently have required curved characteristic, deformation characteristic or characteristic of collapsing with the setting of predetermined breaking part.Be integrated in the specific bending or distortion by means of only its geometric configuration define channel wall of crooked position in side wall sections, and may loading by colliding the power that cause or possible the collapsing or rupture of situation lower channel wall of energy absorbing without the need to considering.
According to design plan, the maximum spacing of crooked position and imaginary line is greater than the wall thickness of side wall sections.Wall thickness in crooked position region can equal the wall thickness with the side wall sections of bight portion adjacent position substantially.Also it is contemplated that, the wall thickness in crooked position region is different from the wall thickness of the side wall sections abutted against on crooked position and correspondingly change.
Maximum spacing due to crooked position and imaginary line is greater than the wall thickness of side wall sections, thus crooked position had both been configured on the outside of conduit wall, was also configured on the inner side corresponded of conduit wall.Crooked position can be designed as the material distortion inwardly or outwardly in side wall sections at this point.Not only can realize the structural weak place if desired of side wall sections thus, also especially can realize curved characteristic and the deformation characteristic of the determination of side wall sections.
According to other design plan, crooked position extends inward in the flow cross section of air flue relative to imaginary line.By this way and method, the curved characteristic especially inwardly pointed to and the deformation characteristic of conduit wall can be provided.When power from act in upper wall section time, the crooked position inwardly offsetted not only can play a role as the joint relative to side wall sections that is adjacent, side form, can also continue equably inwardly to stretch in the flow cross section of air flue.Thus, the design inwardly stretched in flow cross section of crooked position can realize special joint space-efficient curved characteristic and the deformation characteristic of air flue when there is the mechanical load exceeding extreme value.So particularly advantageously, air flue is directly placed on other parts adjacently, and these parts eliminate the distortion outwardly of at least one side wall sections of air flue.
According to other design plan, crooked position stretches out relative to imaginary line.When the side wall sections of air flue is adjacent with clearance envelope, crooked position and corresponding side wall sections can move into this clearance envelope during when being subject to load, above-mentioned design plan is especially feasible and favourable.
According to other design plan, crooked position is designed to predetermined bending part.Crooked position generally refers to the bending section of the almost arbitrary form of side wall sections in this article.In the design of predetermined bending part, the bending spring of this crooked position is relatively little, makes the bending that in fact can be called as in side wall sections.Crooked position can have as the design of predetermined bending part the flanging determined at this point, stretches in flow cross section or stretch out according to this flanging, and flanging can be called as interior angle or exterior angle or interior arris or outer edge.Crooked position imparts the curved characteristic being convenient to define and the deformation characteristic of side wall sections with the design of the predetermined bending part with arris, and especially without the need to considering possible production tolerance and material tolerances.
According to other design plan, crooked position has upper side edge and lower side, and described upper side edge and lower side are relative to imaginary line inclined orientation.Each side can be interconnected on bending or bending part by its mutually opposing end portion section, and the end portion section mutually deviated from of side can coincide according to the specific design of side wall sections and the upper end of side wall sections and/or bottom respectively simultaneously.
In this design plan, the whole side wall sections extending to lower wall section from the upper wall section of conduit wall is used as crooked position.Also it is contemplated that unlike this, be stacked with the end mutually deviated from of the side of the upper and lower end parts crooked position separately of side wall sections and imaginary line.It is contemplated that at this, side wall sections extends substantially point-blank between upper wall section and the outer end of lower wall section, and crooked position only local structure in the side wall sections of other basic linear design.
Crooked position usually by upper side edge and lower side seamlessly to side wall sections transition.At this, side can point-blank but also can design with deviously or swinging back and forth.When side is relative to imaginary line inclined orientation, then obtain needed for the transitional region being used as the center of crooked position or bending part between upper side edge and lower side, relative to the distance of the imaginary line between the upper end and bottom of side wall sections.By the change at the change of side edge length and the corresponding inclination angle of side, can arrange aptly and as required and change curved characteristic and the deformation characteristic of side wall sections and whole conduit wall.
According to other design plan, upper side edge and lower side are with the inclination angle in the same size relative to imaginary line orientation.If such as upper side edge stretches out with the inclination angle of presetting from upper wall section, lower side extends so that the angle relative to imaginary line formed objects is interior mutually with the linkage section of lower side from upper side edge.By this way and method, imaginary line such as can be formed with the form of the form of equicrural triangle or similar isosceles profile with upper side edge and lower side, and it can give the specific required curved characteristic of side wall sections and deformation characteristic.
According to other design plan, crooked position is designed to the protuberance of convex or concave, and described protuberance is usual or stretch in flow cross section, or stretches out when being designed to the protuberance of evagination.Aforesaid side can be configured to the protuberance of indent and/or evagination respectively at this.At this it is contemplated that the side of the protuberance of indent and/or evagination or arcuately intersect, or intersected by arris when forming predetermined bending part.At this it is also conceived that, extend to the whole side wall sections concave or convex lifting as a whole of lower wall section from upper wall section.By the protuberance of at least local inner concave and/or evagination that arrange side wall sections, can on purpose and with predetermined requirement be set up and change mechanical bend characteristic and the deformation characteristic of air flue equally matchingly.
According to other design plan, the conduit wall of air flue, especially air flue has two mutually opposing sidewalls, and each sidewall has at least one crooked position respectively.At this it is contemplated that conduit wall can have substantially (namely ignoring crooked position) rectangular or polygon, especially pentagon or hexagonal cross-sectional profiles.It is also conceived that conduit wall has trapezoidal outline, wherein go up lower wall section and be designed with different length.This causes, and is correspondingly positioned at the plane normal inclined orientation of wall section relative to upper wall section or lower wall section in outside.Air flue can be made to be endowed curved characteristic required under load condition and deformation characteristic relative to the side wall sections (this side wall sections is especially integrated in the crooked position in respective side walls section in conjunction with at least one) of the plane normal inclined orientation of upper wall section or lower wall section.
The upper lower wall section of conduit wall can be directed substantially in parallel to each other.At this it is also conceived that, the relative orientation angularly in relation to one another of upper lower wall section.It is also envisaged that air flue has the cross-sectional geometry of fundamental triangle, wherein go up lower wall section mutual towards end be directly interconnected, each free end simultaneously going up lower wall section is interconnected by least one side wall sections.
According to the other design plan with the air flue of at least two opposite sidewalls, the different geometric cross section profile of air flue can be realized.Thus it is contemplated that two of opposite sidewall crooked positions all inwardly offset relative to imaginary line, homogeneous phase offsets outward or one inwardly and another outwards offsets on the contrary.If two of such as opposite side wall sections crooked positions all inwardly offset, then produce certain closing waist effect to air flue, in contrast, all outside offsetting of two crooked positions of opposite side wall sections causes expanding of conduit wall or air flue.
Closing waist or expand be subject to from apply application force time cause air flue under load condition different curved characteristiies and deformation characteristic.At this point, the curved characteristic of air flue and deformation characteristic require to match with the structure space preset of self-propelled vehicle changeably.
When the crooked position one of opposite side wall sections outwards offsets and another inwardly offsets, also can exceed default extreme value due to the mechanical load occurred and cause collapsing of the parallelogram form of air flue.Respectively according to around the design of the structure space of air flue, this geometric profile shape and the curved characteristic obtained thus and deformation characteristic are favourable.
According to other design plan, side wall sections at least with one of upper wall section and lower wall section single type form.Thus, side wall sections can integrally with at least upper wall section or lower wall section construct.It is also conceived that at least one side wall sections is integrally to upper wall section and/or lower wall section transition.It is also envisaged that all side wall sections are integrally to upper wall section and/or lower wall section transition.In addition, whole air flue can integral type or single type ground structure.
According to other design plan, side wall sections integrally and extend continuously between the upper wall section of conduit wall or air flue.Especially specify, air flue is designed to extrusion or moulding.The conduit wall comprising flow cross section of air flue or air flue especially can be manufactured into plastic injection piece or plastic extruded piece.The design plan of extrusion or moulding form achieves the special of air flue and manufactures economic and cost-saving batch manufacturing.Plastic material is polypropylene (PP) or polyethylene (PE) or foamed plastic, such as expanded polypropylene (EPP) especially.
Air flue can be less than 15cm by the clean cross-sectional area that air flows through
2.At this point, the arris length of rectangle air flue is usually less than 5cm or is less than 4cm.The wall thickness of the wall thickness of air flue or the change of air flue is between 0.3mm to 3mm.
According to other design plan, the crooked position of at least one side wall sections has different geometry design along the longitudinal 2 observation of side wall sections.By this way and method, air flue can longitudinally, namely perpendicular to the direction of its flow cross section provide non-homogeneous, with corresponding structural requirement match and the curved characteristic of localized variation and deformation characteristic.Thus, air flue can need to match from different structures along passage longitudinal extension amount changeably.In addition, curved characteristic and the deformation characteristic of air flue can locally be changed along the change of passage longitudinal extension amount by crooked position, such as to make in the fixed sturcture of air flue between air flue and instrument carrier panel or between instrument carrier panel and vehicle body suitable.
Air flue usually along lateral direction of car (y) extend, and with highlight during object collision by the given curved characteristic of the crooked position in side wall sections and deformation characteristic.The upper wall section of the conduit wall of air flue is in the bottom side of this instrument carrier panel extended below the front windshield of self-propelled vehicle towards cardinal principle.The upper wall section of conduit wall directly can also be connected with instrument carrier panel at this.
When object collision to during instrument carrier panel or due to be applied to mechanical strees on instrument carrier panel beyond the threshold values preset or limit thus cause instrument carrier panel generation mechanically deform time, air flue can rely on its crooked position integrated at least one side wall sections to provide required curved characteristic and deformation characteristic, and this curved characteristic and deformation characteristic are particularly useful on purpose and absorb collision energy and impact force definitely.Air flue can give collision characteristic and the deformation characteristic of self-propelled vehicle and instrument carrier panel improvement.This crash tests especially for self-propelled vehicle is assessed, insurance rating grading and to colliding object as pedestrian or bicycle riding people) protection be favourable.
According to other design plan, the geometry design of the side wall sections of air flue and/or moulding and fixed sturcture suitable, described air flue is connected with instrument carrier panel by fixed sturcture, or instrument carrier panel is fixed on vehicle body by fixed sturcture.Being interconnected or fixingly can having main impact to the deformability of instrument carrier panel of the connection of instrument carrier panel on vehicle body and air flue and instrument carrier panel.Design suitable by the geometry of crooked position and corresponding fixed sturcture, air flue has curved characteristic and the deformation characteristic of optimization according to corresponding fixed sturcture.Thus, the collision characteristic of instrument carrier panel and whole self-propelled vehicle is further optimized.

Crooked position 20 makes corresponding side wall sections 17,18 and whole air flue 10 have good reproducible curved characteristic and deformation characteristic.Crooked position 20 also can collapse or fracture under enough power loads.But this is not force necessity for the deformation process determined.Because the bending and deformation characteristic of air flue is determined particularly by the geometric configuration of crooked position 20 and sets, so compared with the situation of aforesaid predetermined breaking part, tolerance in manufacturing technology of the sidewall thickness that may occur of conduit wall 12 or material character have much smaller impact for the curved characteristic of air flue 10 and deformation characteristic.In addition, the crooked position 20,120,220 owing to arranging at this makes material aging process only have minimum impact to the curved characteristic of air flue 10 and deformation characteristic.As a result, air flue 10 and especially there is almost immovable curved characteristic and deformation characteristic in long-play.
Usually, the wall thickness of the side wall sections 17,18 that crooked position 20 is approximately corresponding to the maximum spacing 24 of imaginary line 22.Spacing 24 this be the inner side of the inside sensing of crooked position 20 distortion relative to the outer side superimposed of side wall sections 18 line 22 between distance.Other spacing definition, the i.e. spacing of the corresponding center line of wall thickness of crooked position 20 and the center line of the wall thickness of side wall sections 17,18 are also admissible and can be included into aforesaid condition.
The crooked position 20 that Fig. 1 schematically illustrates has the profile bending to similar triangular pattern.Crooked position 20 has upper side edge 20a and lower side 20b at this, and they are connected or intersect on the summit of the inside sensing of crooked position 20.On another end, side 20a, 20b are respectively to side wall sections 17,18 transition adjacent separately.Also such as shown in Fig. 3, side 20a, 20b can be designed as substantially rectilinear, profile that is that make two of crooked position 20 interconnective summits of side 20a, 20b comprise bending or arris shape.
According in the design plan of Fig. 2, crooked position 20 is designed to angular.Rectilinear side 20a, 20b of crooked position 20 are basically perpendicular to imaginary line 22 or extend perpendicular to the adjacent outline of each side wall sections 17,18.In contrast, occupy 1/4th of the length being less than respective side walls section 17,18 according to the crooked position 20 of the air flue 10 of Fig. 1, and extending in the length of 1/3 of whole side wall sections 17,18 according to the crooked position 20 in the design plan of Fig. 2.
In the flexible program to this, certainly it is also conceivable that at least one or each side wall sections 17,18 have multiple spaced crooked position 20.
The moulding of single crooked position 20 and profile can be changes arbitrarily.Can imagine arbitrarily each crooked position 20 has angular, polygonal, also or rounding or bending profile or geometric configuration.
In contrast, there is according to the design plan of the air flue 10 of Fig. 1 and 2 the shape of cross section of basic rectangle, and according to the air flue 10 of Fig. 3, there is trapezoidal cross-sectional plane.At this, upper wall section 15 designs shorter than lower wall section 16.But, upper wall section 15 and lower wall section 16 horizontal center in the diagrams of figure 3, to such an extent as to by identical for the interconnective side wall sections in outer end 17,18 substantial distance that upper wall section 15 is respective with lower wall section 16.In upper wall section 15 and the about middle position of lower wall section 16, each side wall sections 17,18 has a crooked position 20 inwardly pointed to.
At this, each crooked position 20 has side 20a, 20b of two basic straight design, they on the summit bending ground of crooked position 20, this is that is in the situation downcrossings forming clear and definite arris.The whole elongation of crooked position 20 is significantly smaller than the half of the elongation of respective side walls section 17,18 at this, thus the end opposing with summit of upper side edge and lower side 20a, 20b overlap with imaginary line 22 to side wall sections 17,18 transition of all the other basic straight design.
Only for simplicity's sake, in Fig. 3 to 7, be not shown specifically the wall thickness of the conduit wall 12 of air flue 10.
By the trapezoidal design of the air flue 10 according to Fig. 3, curved characteristic and the deformation characteristic of air flues 10 different compared with the rectangular design of Fig. 1 and 2 can be produced.Side wall sections 17,18 or upper end and the interconnective line 22 of bottom 17a, 18a, 17b, 18b difference are extended with the angle preset relative to the plane of upper wall section 15 and/or lower wall section 16.
Crooked position 220 shown in design in addition shown in Fig. 4, this crooked position extends and instead of completely at this point in whole side wall sections 17,18 should the linearly extended side wall sections 17,18 of cardinal principle.Crooked position 220 has indent or approximate indent and the protuberance inwardly pointed at this, and the upper end of side segment that is that wherein swell or that form thus and the outer end of bottom 18a, 18b and upper wall section 15 and lower section 16 coincide.
The design plan of another kind of crooked position 120 shown in Fig. 5.At this, crooked position 120 is also extend in whole side wall sections 17,18.But with according to the design plan of Fig. 4 unlike, crooked position 120 has rectilinear side 120a, 120b that two direct neighbors connect.Upper side edge 120a is connected with upper wall section 15 in the region of the upper end 18a of side wall sections 18.Lower side 120b to be coincided with the bottom 18b of side wall sections 18 by its bottom and to be at this point also directly connected with lower wall section 16.
The summit that two rectilinear upper side edges and lower side 120a, 120b of crooked position 120 intersect forms exterior angle.In final effect, air flue 10 has hexagon outline at this point.At this, the outside of the line 22 of summit and the illusion of crooked position 120 self between the upper end 18a and bottom 18b of side wall sections 18.Two side 120a, 120b forming crooked position 120 extend with identical or almost identical angle a, b relative to imaginary line 22 at this.Inclination angle a, b have approximately equal size at this.Two sides 120a, 120b and imaginary line 22 form the triangle of about isosceles jointly.
In the design plan of the air flue 10 shown in Fig. 6, opposite side wall sections 17,18 inwardly and outwards offsets on the contrary, and this side wall sections is provided with corresponding crooked position 20,120.In contrast the crooked position 20 shown in left side inwardly offsets relative to imaginary line 22, and the crooked position 120 described in right side outwards offsets relative to aforesaid line 22.When from apply power to upper wall section 15 time, crooked position 20,120 form respectively run-on point and swing point, make corresponding side 20a, 20b or 120a, the mutual clamping of 120b.Thus, the interconnective respective vertices of side 20a, 20b, 120a, 120b of crooked position 20,120 approximately moves right along longitudinal direction of car (x) relative to the installation site in self-propelled vehicle.
Fig. 7 illustrates the another kind of design plan of air flue 10.At this, two opposite side wall sections 17,18 are designed to consistent or symmetrical substantially.Two crooked positions 20 are inwardly charged in the flow cross section 14 of air flue 10.Described crooked position has upper side edge 20a and lower side 20b respectively, and wherein upper side edge and lower side 20a, 20b protrude in upper wall section 15 and lower wall section 16 respectively.
The identical point that the shown geometry design scheme of different air flue 10 is general is, is namely manufactured into plastic injection piece or plastic extruded piece.At this point, all portions section of the formation conduit wall 12 of air flue and part can be interconnected single type or be designed to integral type.
Finally shown in Figure 10ly to be out of shape, before in fig .9 with the hexagonal air flue 10 shown in initial condition due to application force.Because the application force exceeding pre-set threshold value acts on (this application force such as can be produced by the collision of object 26) on instrument carrier panel 6, cause this instrument carrier panel to point to ground displacement downwards along vehicle-height direction (z), this finally causes deformation and the distortion of the setting of originally shown in fig .9 air flue 10.Such as by Fig. 9 with 10 more known, the application force acted on instrument carrier panel 6 not only causes instrument carrier panel 6 to move down, and also causes the distortion of air flue 10.The summit of two crooked positions 120 outwards offsets due to application force, makes upper wall section and lower wall section 15,16 close to each other when absorbing mechanical energy.
In the view of Fig. 9, fixed sturcture 9 is also shown, air flue 10 can be fixed on the bottom side of instrument carrier panel 6 by fixed sturcture 9.Fixed sturcture 9 can have different designs.Thus, air flue 10 can by different and along passage longitudinally spaced attachment point be structurally connected with instrument carrier panel 6.Similarly, fixed sturcture 9 also may be used for instrument carrier panel 6 to be fixed on vehicle body 2.Especially can specify thus, the concrete geometry design of each crooked position 20,120,220 is with the position of fixed sturcture 9 and move towards suitable.
Each crooked position 20; 120; The geometry design of 220 can change in the longitudinal direction of air flue 10.But crooked position 20,120,220 also can have constant shape of cross section in the longitudinal extension section of air flue 10, this is particularly useful for manufacturing air flue with expressing technique.
