The utility model discloses a front longitudinal beam reinforcement for an automobile, aiming to solve the problem that the existing front longitudinal beam of an automobile is prone to bending after collision and the energy absorption is insufficient. The utility model comprises a reinforcement body, and the two opposite sides of the reinforcement body are respectively provided with an upper flange and a lower flange that are turned up to the same side, and a plurality of positive energy absorption grooves are provided on the surface of the reinforcement body close to one end, and a plurality of upper energy absorption grooves and lower energy absorption grooves are respectively provided on the upper flange and the lower flange. The reinforcement is welded on the front longitudinal beam of the automobile. When the automobile collides, the front cross beam and the energy absorption box are crushed first. When the energy is transmitted to the front longitudinal beam, the front longitudinal beam and the reinforcement are crushed step by step because the front part of the reinforcement in front of the front longitudinal beam is provided with a positive energy absorption groove, an upper energy absorption groove, and a lower energy absorption groove. The reinforcement improves the energy absorption mode of the front longitudinal beam, makes the front longitudinal beam less likely to bend, and greatly improves the energy absorption effect of the front longitudinal beam.
Description
Technical field
The utility model relates to the attaching parts on a kind of automobile, and more particularly, it relates to a kind of reinforcement that is connected on the automobile front side member.
Background technology
Automobile is when bumping; Can produce lot of energy; The automobile front side member is as the device of main transmission energy, and the deformation pattern in collision process and the order of distortion directly have influence on what of energy of absorption, and reasonably deformation pattern absorbs more energy; Therefore the energy that passes to the crew module is just less relatively, and is also less to occupant's injury.Existing longeron deformation pattern is unreasonable, and the longeron front portion is by conquassation, but bending occurs at longeron total anterior, and energy absorbing is insufficient, can not satisfy development requirement.In order to improve the deformation pattern of longeron, the someone has designed a kind of longeron brace panel, like Chinese patent notification number CN201613939U; On October 27 2010 day for announcing, the name of utility model is called a kind of longeron brace panel, and its main body is a slab construction; The two ends of main body have flanging; The bottom of main body and top all have flanging, and top flap is provided with knock hole, and this longeron brace panel is welded on the deformation pattern of having improved longeron on the automobile front side member; Ability for the energy-absorbing of front side member improves, but the DeGrain that improves.
Summary of the invention
The utility model is prone to bending after having overcome existing automobile front side member collision, and the inadequate deficiency of energy absorbing provides a kind of automobile front side member reinforcement, and it has improved the energy-absorbing modes of front side member, has improved the energy absorption ability of front side member greatly.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: a kind of automobile front side member reinforcement; Comprise the reinforcement body; The relative dual-side of said reinforcement body is respectively equipped with the upper overturning of digging to the same side and following flange, and the reinforcement body is provided with some positive energy-absorbing grooves near the surface of an end, is respectively equipped with some energy-absorbing groove and following energy-absorbing grooves gone up on the upper and lower flange of upper overturning.Upper overturning and following flange have increased the intensity of reinforcement body.Reinforcement is welded on the automobile front side member; Automobile is when bumping; At first front cross rail and energy-absorbing box are by conquassation; When energy passes to front side member,, make the realization of front side member and reinforcement step by step by conquassation because the front portion of reinforcement before the front side member is provided with positive energy-absorbing groove, goes up the energy-absorbing groove, energy-absorbing groove down.Reinforcement has improved the energy-absorbing modes of front side member, makes front side member be difficult for bending takes place, and has improved the energy-absorbing effect of front side member greatly.
As preferably; Said positive energy-absorbing groove has four at least; Last energy-absorbing groove has three respectively at least with following energy-absorbing groove, and positive energy-absorbing groove is parallel to each other, and last energy-absorbing groove is parallel to each other with following energy-absorbing groove; Last energy-absorbing groove is spaced apart with positive energy-absorbing groove, and following energy-absorbing groove is spaced apart with positive energy-absorbing groove.Last energy-absorbing groove is spaced apart with positive energy-absorbing groove, and following energy-absorbing groove is spaced apart with positive energy-absorbing groove, helps front side member to realize step by step by conquassation.
As preferably, said flange down is provided with the V-notch of depression away from energy-absorbing groove ends down.Satisfying under the prerequisite of requirement of strength, breach has been saved material, has reduced productive costs.
As preferably, be provided with auxiliary hole near last energy-absorbing groove location on the said upper overturning.Auxiliary hole satisfies the technological requirement of front side member reinforcement.
As preferably, said upper overturning is provided with bolt connecting hole with following flange.The upper overturning that is welded on the reinforcement of automobile front side member is provided with bolt connecting hole with following flange and makes things convenient for other parts to be mounted on the reinforcement.
Compared with prior art, the beneficial effect of the utility model is: reinforcement not only realized the integrally-built booster action of front side member, and make front side member in the process of bumping by conquassation step by step, make front side member be difficult for bending takes place, fully absorb energy.
