The utility model content
A task of the utility model is, a kind of guard bar structure of aforementioned type is provided, and it has better distortion performance and has bigger prevention ability when Vehicular impact.
This task will solve through a guard bar structure with claim 1 characteristic.Guard bar structure according to the utility model has following characteristic specifically:
A plurality of being fixed on perhaps can be fixed on the moulding column in the ground,
The guardrail cross bar that at least one extends along the longitudinal axis,
At least one is used to support the support component between moulding column and guardrail cross bar of guardrail cross bar, and it has a canned paragraph that is used to install the guardrail cross bar,
Intermediary element between support component and guardrail cross bar,
Intermediary element has the surface of a diagonally extending; Can regulate the guardrail cross bar with respect to the angle of inclination between the moulding shaft longitudinal axis through this surface; Support component has a leg at least simultaneously, and it extends to the guardrail cross bar from canned paragraph, and support component also has two brace summers that extend in parallel; Its towards one with its under the longitudinal axis of moulding column extend less than the angle of 90 degree, be used for when collision, being provided with one and should be out of shape direction.
Through of the combination (this intermediary element make guardrail cross bar and the longitudinal axis that become t shore an angle arranged) of asymmetric support component with intermediary element; Can prevent that especially the guardrail cross bar from descending when the guard bar structure continuous deformation so that the deformability of guard bar structure is improved greatly.Can make the bigger vehicle that is collided of quality be supported on the guardrail cross bar like this and change its track.Support component promotes the guardrail cross bar to tilt towards ground, and this support component can increase the gradient of guardrail cross bar through its asymmetrical structure and its deformability and can make the guardrail cross bar rest on the position of a raising and do not crossed by a collision vehicle.Through support component also have two brace summers that extend in parallel this characteristic (these two brace summers towards one with its under the longitudinal axis of moulding column extend less than the angle of 90 degree; Be used to be provided with one and should be out of shape direction); Can reach a controllable deforming towards predetermined direction, this has further improved the reliability according to the system of the utility model.
The angle of inclination of guardrail cross bar can not only prevent that it from descending, and the guardrail cross bar when continuous deformation owing to there is this angle of slope can be displaced to the position of a raising.This support component has asymmetrical structure for this reason; The leg that extend towards the guardrail cross bar that root of support component top is arranged relatively tiltedly and its distortion has delay, and the guardrail cross bar is enlarged towards the angle of slope of ground and can prevent that the guardrail cross bar from descending when big impact force occurring in this way.Can realize that through brace summer when collision, at first the guardrail cross bar moves, and promptly just in time is and the prior art reverse effect up.In other words; Even the guardrail cross bar comes off from the moulding column---compare the position that still can reach a raising with prior art (Fig. 1) and perhaps can rise to one with respect to ground with by the higher position of collision vehicle, change track so relatively large vehicle can rest on guardrail cross bar next door and pass through it through angle of slope and acclivitous brace summer.
These two brace summers also have the another one effect.According to the difference of design, utilize them to absorb a large amount of collision energies through guard bar structure.They play a part so-called deformation element.At vehicle with before vertical columns really contacts, through brace summer act on its distortion the time can eliminate a large amount of collision energies.In other words, prolonged the bump of vehicle, so can reduce deceleration greatly and for occupant's load through the deformation time of brace summer.
Other a kind of form of implementation of the utility model is set to, and at least one longitudinal axis towards the leg of guardrail cross bar and the moulding column under it has certain angle on the support component.Angle between the longitudinal axis of the leg of support component and moulding column can influence the deformability of support component, that is to say that the deformation time process of support component can be determined.This during for vehicle collision controlled deformation process have very significant meaning.
According to preferred form of implementation of the utility model; Support component has two pieces and stretches out from canned paragraph; Towards the leg of guardrail cross bar, every leg is being to extend on certain angle with the moulding shaft longitudinal axis respectively, and the leg that stretches out simultaneously is different with angle between the canned paragraph.During for the decline of avoiding the guardrail cross bar when the vehicle collision or at its continuous modification the guardrail cross bar is moved towards leaving ground direction up; According to the utility model; Two angles between the leg of support component and the canned paragraph are by following form design; Being support component at first is out of shape near that root leg of ground, thereby can keep the angle of slope between guardrail cross bar and the moulding shaft longitudinal axis at least.
The utility model can be set in addition, and two brace summers become the angle between 85 ° to 75 ° with the longitudinal axis of its affiliated moulding column.Preferably the angle of the longitudinal axis of two brace summers and its affiliated moulding column is arranged to about 84 °.Formed a big lever arm through relatively large angle between the longitudinal axis of two brace summers and the moulding column under it, can very big deformation force have been imported in this guard bar structure through this lever arm.Angle through two brace summers of corresponding selection can be so that the distortion performance of brace summer when colliding be controlled especially.
According to the setting of structure design, these two brace summers are vertical legs of the first U-shaped structure, and these two vertical leg legs horizontal with it are fixed on above the moulding column.According to the utility model, the free end of two vertical legs of the first U-shaped structure links to each other with the horizontal leg of the second U-shaped structure in addition, and the horizontal leg of the second U-shaped structure has constituted canned paragraph.Therefore according to this form of implementation, there are two U-shaped structures to link to each other a U-shaped structure and a U-shaped structure with canned paragraph and two free legs near the guardrail cross bar near the formation brace summer of moulding column in intermediary element.
Interchangeablely in addition be; First side of the parallelogram sturcutre that these two brace summers are a sealing abreast; This parallelogram sturcutre links to each other with the moulding column through one of which second side simultaneously, is fixed on through its another second relative side perhaps to constitute canned paragraph on the canned paragraph.Therefore two brace summers of this replacement form of implementation are the parts of an enclosed construction, the second U-shaped structure be attached thereto or two towards the leg of guardrail cross bar directly from it face stretch out, such as welding in the above.
Preferred form of implementation of the utility model is set to, the second U-shaped structure near having than bigger angle between an other leg and the moulding shaft longitudinal axis between that root leg of ground and the moulding shaft longitudinal axis on the support component.Can guarantee like this that when vehicle collision at first following that root leg distortion and guardrail cross bar enlarge with respect to the gradient of the moulding shaft longitudinal axis under it.Can guarantee like this that when vehicle collision perhaps prevent to collide vehicle crosses the guardrail cross bar to the prevention ability of move up supported and the raising guard bar structure of guardrail cross bar.On support component according to the guard bar structure of the utility model; That root and moulding shaft longitudinal axis have the leg of wide-angle more owing to have longer lever arm and when vehicle collision, at first be out of shape, so the gradient between guardrail cross bar and the moulding shaft longitudinal axis increases and the guardrail cross bar moves to a higher position because of the vehicle that collides.
Therefore confirmablely from this respect be that according to another form of implementation of the utility model, support component is not equal to 90 ° near the angle between the longitudinal axis of that root leg of ground and moulding column.
In addition guard bar structure particularly the distortion performance of support component can be affected in the following manner, promptly according to another form of implementation of the utility model, the length of two legs that stretch out from canned paragraph is unequal on second U-shaped structure of support component.

The specific embodiment
Understand for technical characterictic, purpose and effect to the utility model have more clearly, contrast the specific embodiment that accompanying drawing specifies the utility model at present.
Fig. 2 a has showed a decomposition part phantom drawing according to the guard bar structure of the utility model, and guard bar structure is generally represented with 100.
Can see moulding column 112 among Fig. 2 a, it is inserted on the ground U that does not have here to describe in detail, is used for fixing guard bar structure 100.Except showing moulding column 112, also showed a guardrail cross bar 114 that extends along the travel (not shown) among Fig. 2.Between the protected apron of moulding column 112 and guardrail cross bar 114, support component 116 has been installed, guardrail cross bar 114 is fixed on the moulding column 112 through support component 116.To further describing of support component 116,4a and 4b with reference to Fig. 3.
The support component 116 of this form of implementation has the first U-shaped structure 117 and the second U-shaped structure 119.The first U-shaped structure 117 is made up of two parallel vertical legs 121,123, between itself and the vertical direction, promptly corresponding to the general y direction that embeds the situation compacted under column 112 of ground, an angle γ who is approximately 84 ° is arranged.These two vertical legs 121,123 couple together through horizontal leg 125.The effect of this horizontal leg is, the first U-shaped structure 117 and whole support component 116 are fixed on the moulding column 112 under it through set bolt 127.
The first U-shaped structure 117 links to each other with the second U-shaped structure 119.The horizontal leg 118 of the free end of two vertical legs 121,123 and the second U-shaped structure 119 welds.The horizontal leg 118 of the second U-shaped structure 119 has constituted so-called canned paragraph.Extend two legs 122,124 from this canned paragraph, it extends to guardrail cross bar 114.The leg 122 and 124 of two extensions is used to support guardrail cross bar 114.
The intermediary element 120 of a wedge shape has been installed towards a side of guardrail cross bar 114 at horizontal leg 118.This intermediary element has a centre bore and is used to install and fix bolt.The effect of this wedge shape is to make guardrail cross bar 114 with respect to vertical direction (vertical L of moulding column 112) certain gradient arranged when mounted.Intermediary element 120 can be directly on support component 116 molded or independent parts.
Fig. 2 a and b show in addition, and protected apron 114 is installed on the moulding column 112 through being threaded with support component 116.
Fig. 3 has described the lateral view of a guard bar structure 100.Therefrom can find out moulding column 112 and guardrail cross bar 114 and be installed in moulding column 112 and guardrail cross bar 114 between support component 116.Support component 116 links to each other with moulding column 112 through the first U-shaped structure 117.Because two supporting traverse 121,123 parallel and same length, laterally leg 118 extends in vertical direction, promptly is parallel to the vertical of moulding column 112.Wedge shape intermediary element 120 leans against as on the horizontal leg 118 of canned paragraph and have an inclined plane 120b who deviates from surperficial 120a through surperficial 120a, and guardrail cross bar 114 leans against on this surface through its interlude when assembling.Through guardrail cross bar 114 being leaned against on the inclined plane 120b of intermediary element 120, guardrail cross bar 114 is approximately at the longitudinal axis (not illustrating here) with moulding column 112 on 5 ° the wedge angle and extends.This that is to say that the inclined plane 120b of intermediary element 120 makes the angle of slope between guardrail cross bar 114 and moulding column 112 longitudinal axis L to regulate.Angle of slope between the longitudinal axis L of guardrail cross bar 114 and moulding column 112 in addition can through or interchangeable be to regulate by the leg 122 of second U-shaped structure 119 and 124 length and angle of inclination through support component 116.
Fig. 3,4a and 4b have described the non-symmetrical configuration of the second U-shaped structure 119 of support component 116, and this is very important for cooperating of the angle between the longitudinal axis L of support component 116 and the guardrail cross bar of confirming through intermediary element 120 114 and moulding column 112.Leg 122 and vertical direction, promptly the angle beta of the direction of the longitudinal axis L of moulding column 112 (being 90 ° here) is less than the longitudinal axis L of moulding column 112 and angle (being 118 ° here) near 124 ° of the legs of ground.
Can find out from figure that in addition two supporting traverses 121 and 123 extend around an angle γ (being 6 °) from being fixed on the horizontal leg 125s of moulding column 112 obliquely here.So the horizontal leg 118 of the first U-shaped structure 117 and the second U-shaped structure 119 has constituted a parallelogram sturcutre.
Can produce favorable influence to the distortion performance of guard bar structure 100 when the vehicle collision through support component 116 this structure designs, will be described in detail this below.
Fig. 5 a has described the action principle of guard bar structure 100 when the vehicle collision to 5d.
Fig. 5 a has described the guard bar structure 100 before the collision.Guardrail cross beams 114 is positioned at and is higher than the height that ground U is h1.Support component 116 is in original shape.One vehicle collision is on guardrail cross beams 114, and by force arrows F representes here.
Fig. 5 b shows, after the collision at first two supporting traverses 121 with 123 according to moving up through the predetermined deformation direction of angle γ (Fig. 4 b), the while parallelogram sturcutre remains unchanged basically.So guardrail cross beams 114 moves according to arrow P obliquely, that is to say that the height between guardrail cross beams 114 and the ground U rises to h2, guardrail cross beams 114 moves backward simultaneously.The state that Fig. 5 b describes is an intermediateness.Distortion impact force F major part through described two supporting traverses 121,123 obtains discharging.Guardrail cross beams 114 only upwards or backward moves, and does not lose its prevention ability to vehicle, and on the contrary, it is positioned at a position of (because higher) preferably, is perhaps crossed thereby can avoid guardrail cross beams 114 to be thrust.
Under impact force F further acted on, moulding column 112 and two supporting traverses 121,123 were finally according to crooked shown in Fig. 5 c.Under this state, guardrail cross beams 114 reaches its extreme higher position (h3), and it still links to each other with support component 116.Through this distortion performance of guard bar structure 100, guardrail cross beams 114 is all the time optimally towards the collision vehicle.
The further effect compacted under column 112 that Fig. 5 d has described at impact force F finally bends to subaerial state.At this moment guardrail cross bar 114 comes off from support component 116 or moulding column 112.Described hereinly be, be used for guardrail cross bar 114 is fixed on set bolt 129 fractures of support component 116, that is to say that set bolt 129 has constituted one and answered fracture position.Guardrail cross bar 114 also can come off by following mode in addition, and the solder joint that promptly is positioned between supporting traverse 121,123 and the transversary 118 is broken.Come off and also can realize, come off from moulding column 112 fully such as support component 116 through other modes.Although guardrail cross bar 114 comes off from moulding column 112, guardrail cross bar 114 is positioned at height h3 all the time or rises to height h4 and it is stopped or draw the ability of colliding vehicle and obtains bigger performance.With other words in other words, guardrail cross bar 114 comes off from support component 116 through the fracture of connecting bolt 129, and can rise to height h4.Under the state shown in Fig. 5 d, two supporting traverses 121,123 produce maximum distortion.
Fig. 5 e has described the state of guard bar structure 100, and under this state, moulding column 112 further almost completely bends to ground under the effect at impact force F, that is to say maximum distortion.From the coming off of support component 116 or moulding column 112, guardrail cross beams 114 rises to height h5 or remains unchanged through guardrail cross beams 114, even under this state, moulding column 112 still plays a part traction belt.
Fig. 6 has described the sketch map according to Fig. 4 b, and it is second form of implementation of the utility model.
A parallelogram sturcutre 150 has replaced being used to constitute brace summer 121; 123 the first U-shaped structure 117; It has corresponding to 121; 123 parallelogram limit 152,154 and corresponding to laterally the another one parallelogram limit 156 and a parallel with it parallelogram limit 158 of leg 125, this limit leans against on the horizontal leg of the second U-shaped structure 119.First form of implementation of its operating principle and front is similar, especially with reference to Fig. 5 a to 5d.Parallelogram sturcutre 150 is used under collision status, being provided with one should be out of shape and play a part simultaneously the deformation element that absorbs most of impact force.
Guard bar structure is out of shape on a definite direction when utilizing the utility model to can be implemented in collision; This realizes in the following manner; At first guardrail cross beams upwards and towards collision course moves behind the absorbing impact energy, and this is used for the absorbing impact energy and prevents to collide vehicle above guardrail cross beams.When having only deformation element to be badly deformed, and the moulding column is finally crooked, and guardrail cross beams just comes off from the moulding column, but in the position of a rising, can keep it to stop the ability of vehicle like this.
Combine accompanying drawing that the embodiment of the utility model is described above; But the utility model is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the utility model.
