Abstract
The utility model relates to back reinforcement structure for a back stringer of an automobile. The utility model comprises a back stringer and a back reinforcing element of the back stringer, wherein the back reinforcing element of the back stringer is a U-shaped steel plate, and the bottom of the U-shaped reinforcing element is provided with a long elliptic lug boss which is used for enhancing the intensity of the reinforcing element. The middle of the lug boss is provided with a coating technology drainage hole, and the U-shaped reinforcing element is internally inlaid in a U-shaped inner fovea on behind the back section of the stringer. Because the bottom of the reinforcing element of the utility model is provided with the lug boss, certain space is formed on two chamfering points after the stringer is welded and combined to form a water flowing passage, and in this way, the utility model not only ensures requirements for the intensity of the back stringer, but also improves welding and painting manufacturability.
Description
Technical field
The utility model belongs to auto body accessory technical field, is specifically related to a kind of floor side member rear portion additional strengthening of vehicle.
Background technology
For to floor side member rear booster action, adopted floor side member rear portion reinforcement on the existing automobile, but existing floor side member rear portion reinforcement is because undercapacity often causes floor side member back segment rear portion torsional deflection; General in addition reinforcement mostly is simple " U " type structure, exists not enough on welding and coating process.
Summary of the invention:
The purpose of this utility model is at the prior art above shortcomings, a kind of new automobile rear longitudinal girder rear portion additional strengthening is proposed, by longeron rear portion reinforcement is improved design, increase the intensity at longeron back segment rear portion, improve the manufacturability of welding, application.
The technical solution of the utility model is as follows:
Automobile rear longitudinal girder rear portion additional strengthening includes floor side member and floor side member rear portion reinforcement, floor side member rear portion reinforcement is one " U " shaped steel plate, in the bottom of " U " type reinforcement one long disciform boss is arranged,, in the middle of boss, have a coating process water hole in order to increase the intensity of reinforcement.Be somebody's turn to do in " U " shape indent at the back segment rear portion that is set in longeron in " U " type reinforcement.
Since the utility model in the reinforcement bottom design boss, after making up with the floor side member welding, just reserved certain space at two chamfering places, become the flowing water passage, so both guarantee to increase the requirement of floor side member intensity, also improved the manufacturability of welding and application.
Description of drawings:
Fig. 1 is the scheme drawing of automobile rear longitudinal girder rear portion additional strengthening;
Fig. 2 is the sectional schematic diagram of automobile rear longitudinal girder rear portion additional strengthening;
Fig. 3 is the structural representation of floor side member rear portion reinforcement wherein;
Fig. 4 is the sectional schematic diagram of floor side member rear portion reinforcement wherein.
The specific embodiment:
Referring to Fig. 1 and Fig. 2,, automobile rear longitudinal girder rear portion additional strengthening is made up of floor side member 2 and floor side member rear portion reinforcement 1, and 12 is bond pad locations among Fig. 1; Among Fig. 2, be set in the floor side member rear portion reinforcement 1 in " U " shape indent at back segment rear portion of floor side member 2.In conjunction with Fig. 3 and Fig. 4 as seen, wherein floor side member rear portion reinforcement 1 is one " U " shaped steel plate, long 400mm, thickness is 1.4mm, make a long disciform boss 32 in the bottom of the floor side member rear portion of " U " type reinforcement 1, increased the intensity of reinforcement, the coating process water hole 31 that to have a diameter in the centre of boss be 10mm.After edge advances floor side member 2 in the floor side member rear portion reinforcement 1, floor side member rear portion reinforcement 1 is respectively each place's face of weld 23 with the sticking part of floor side member 2 in the side, the boss 12 of floor side member rear portion reinforcement is another place's face of weld 22 with the bottom of floor side member, just reserve space 21 at two chamfering places, become the flowing water passage.
Above-mentioned automobile rear longitudinal girder rear portion additional strengthening when on automobile, using be about each one, complete symmetry, principle is identical.
Claims (1)
1, automobile rear longitudinal girder rear portion additional strengthening, include floor side member and floor side member rear portion reinforcement, it is characterized in that: floor side member rear portion reinforcement is one " U " shaped steel plate, one long disciform boss is arranged in the bottom of " U " type floor side member rear portion reinforcement, in the middle of boss, have a coating process water hole, be somebody's turn to do in " U " shape indent at the back segment rear portion that is set in longeron in the reinforcement of " U " type floor side member rear portion.
