Abstract

The utility model discloses a solebar strengthens structure, include the reinforcement body that is used for with solebar middle section fixed connection, the cross -section of reinforcement body is the U type, at the bottom of this reinforcement body outer surface of the wall along vertically being equipped with the depressed part to the indent, the depressed part internal fixation has the reinforced pipe. The utility model discloses can effectively increase the whole anti deformability in longeron middle section, avoid producing the local stress, promote crashworthiness, satisfy the performance requirement under various complicated collision operating modes, and overall structure be simple, the manufacturing of being convenient for.

Description

Longitudinal beam adds competent structure

Technical field

The utility model relates to the body frame structure for automotive of vehicle, and particularly a kind of longitudinal beam adds competent structure.

Background technology

Longeron is one of crucial building block of vehicle frame, for vehicle being played to carrying effect. At present in order to meetCollision demand, passenger vehicle (as the vehicle such as car, SUV) need be set up reinforcement in its longeron stage casing. ExistingIn technology, longitudinal beam stage casing reinforcement is high strength steel plate by cold stamping or heat stamping and shaping, although possessCertain stiffening effect, but affected by reinforcement cross sectional shape, easily produces local stress, can not meet respectivelyPlant the performance requirement under complicated collision operating mode.

Therefore, being badly in need of exploitation one can effectively increase longeron stage casing entirety non-deformability, avoids generation officePortion's stress, promotes collision performance, meets the performance requirement under various complicated collision operating modes, and overall structureSimply, the longitudinal beam of being convenient to processing and manufacturing adds competent structure.

Summary of the invention

In view of this, the purpose of this utility model is to provide a kind of longitudinal beam to add competent structure, can be effectiveIncrease longeron stage casing entirety non-deformability, avoid producing local stress, promote collision performance, meet respectivelyPlant the performance requirement under complicated collision operating mode, and overall structure is simple, is convenient to processing and manufacturing.

Longitudinal beam of the present utility model adds competent structure, comprises for adding of being fixedly connected with longitudinal beam stage casingStrong part body, the cross section of described reinforcement body is U-shaped, this reinforcement body diapire outer surface is longitudinally establishedThere is the depressed part concaving, in described depressed part, be fixed with reinforced pipe.

Further, one end of described reinforcement body has outward extending extension, and described depressed part is along addingExtend to end, extension at strong part body middle part.

Further, described depressed part is arc groove, and described reinforced pipe is weldingly fixed in depressed part.

Further, described reinforced pipe arranges along depressed part bearing of trend, with depressed part conformal.

Further, on the sidewall of described reinforcement body both sides, be respectively equipped with for being fixedly connected with longitudinal beamFlange.

Further, described reinforcement body adopts high strength steel plate by cold stamping shaped.

The beneficial effects of the utility model: longitudinal beam of the present utility model adds competent structure, by reinforcementIn the depressed part of body, reinforced pipe is set, can effectively avoids reinforcement body to produce local stress, Jin ErzengAdd longitudinal beam stage casing entirety non-deformability, promote collision performance, meet under various complicated collision operating modesPerformance requirement, and overall structure is simple, is convenient to processing and manufacturing.

Detailed description of the invention

Fig. 1 is structural representation of the present utility model, and the A-A that Fig. 2 is Fig. 1 is to schematic diagram, and Fig. 3 is Fig. 1B to schematic diagram, the C that Fig. 4 is Fig. 1 is to schematic diagram, as shown in the figure: the longitudinal beam of the present embodiment addsCompetent structure, comprises the reinforcement body 1 for being fixedly connected with longitudinal beam stage casing, described reinforcement body 1Cross section be U-shaped, convenient be connected and fixed with longitudinal beam, to improve longitudinal beam bearing capacity, this reinforcementPart body 1 diapire outer surface is longitudinally provided with the depressed part 2 concaving, and in described depressed part 2, is fixed with reinforcementPipe 3, in this enforcement, reinforced pipe 3 adopts the steel pipe of diameter 24mm, by reinforced pipe 3 is set, can be effectiveAvoid reinforcement body 1 to produce local stress, and then increase longitudinal beam stage casing entirety non-deformability, carryRise collision performance, meet the performance requirement under various complicated collision operating modes.

In the present embodiment, one end of described reinforcement body 1 has outward extending extension 4, described depressionPortion 2 extends along reinforcement body 1 middle part to 4 ends, extension, to improve the intensity of reinforcement body 1,Further improve bearing capacity, and be convenient to assemble with reinforced pipe 3.

In the present embodiment, described depressed part 2 is arc groove, and described reinforced pipe 3 is weldingly fixed on depressed part 2In, simple in structure, convenient installation fixed, and further improves the intensity of reinforcement body 1.

In the present embodiment, described reinforced pipe 3 is along depressed part 2 bearing of trend settings, with depressed part 2 conformals,Collision performance be can effectively promote, tare and cost reduced.

In the present embodiment, on described reinforcement body 1 both sides sidewall, be respectively equipped with for fixing with longitudinal beamThe flange 5 connecting, for being welded and fixed with longitudinal beam, to improve the company of reinforcement body 1 and longitudinal beamConnect intensity, firm and reliable connection.

In the present embodiment, it is cold stamping shaped that described reinforcement body 1 adopts high strength steel plate to pass through, and intensity is high,Facilitate processing and manufacturing.

Finally explanation, above embodiment is only unrestricted in order to the technical solution of the utility model to be described,Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art shouldWork as understanding, can modify or be equal to replacement the technical solution of the utility model, and not depart from this realityBy aim and the scope of new technique scheme, it all should be encompassed in the middle of claim scope of the present utility model.
