A seat frame front cross member 10 of a vehicle according to an embodiment of the present invention is described below with reference to the drawings.

As shown in fig. 1 to 6, a seat frame front cross member 10 of a vehicle according to an embodiment of the present invention includes a beam main body 11, a plurality of upper projections 12, and a plurality of lower projections 13 (up-down and front-rear directions are shown by arrows in the drawings and are for convenience of description only and are not limiting with respect to the actual arrangement direction).

The upper protrusions 12 are provided on the girder main body 11 and protrude upward, and a plurality of the upper protrusions 12 are arranged along the length direction of the girder main body 11. The lower protrusions 13 are provided on the girder main body 11 and protrude downward, and a plurality of the lower protrusions 13 are arranged in a length direction of the girder main body 11.

According to the utility model discloses seat frame front beam 10 of vehicle, through set up a plurality of upper humps 12 and a plurality of lower arch 13 in the roof beam main part of seat frame front beam, compare simple straight line crossbeam structure among the correlation technique, the rigidity of front beam 10 can be promoted in a plurality of bellied settings, reduce the sensitivity of front beam 10 transmission vibration to restrain the transmission of vibration, reduce the vibration that the personnel of taking on this seat felt, improve personnel's of taking travelling comfort.

In addition, because the upper bulge 12 and the lower bulge 13 have opposite bulge directions, the upper bulge 12 and the lower bulge 13 have buffering effects in different directions, vibration is effectively dispersed, the vibration is prevented from being excessively concentrated on the front cross beam 10, the transmission of the vibration is further relieved, and the comfort of passengers is further improved.

In addition, because the upper bulge 12 and the lower bulge 13 are both a plurality of, the stress of the beam main body 11 can be more uniform, and the situation that vibration is too obvious due to the fact that vibration is concentrated at one position is avoided, so that the comfort of passengers is further improved.

Therefore, the seat frame front cross member 10 of the vehicle according to the embodiment of the present invention has the advantages of good damping effect, etc.

In some embodiments of the present invention, as shown in fig. 1 to 6, a seat frame front cross member 10 of a vehicle according to an embodiment of the present invention includes a beam main body 11, a plurality of upper protrusions 12, and a plurality of lower protrusions 13.

Specifically, the plurality of upper projections 12 may be arranged at intervals in the longitudinal direction of the beam body 11, and the plurality of lower projections 13 may be arranged at intervals in the longitudinal direction of the beam body 11. The plurality of upper protrusions 12 may be different in size in the length direction of the beam main body 11. The plurality of lower protrusions 13 may be different in size in the length direction of the beam body 11. This can further facilitate improvement in the vibration damping effect of the seat frame front cross member 10 of the vehicle, and further improve the comfort of the occupant.

Alternatively, as shown in fig. 2 to 4, one of the upper protrusion 12 and the lower protrusion 13 is a triangular protrusion and the other is a circular arc protrusion. Specifically, the upper protrusion 12 may be a triangular protrusion and the lower protrusion 13 may be a circular arc protrusion. Thus, the rigidity of the front cross member 10 can be further improved by using a structure having a relatively stable triangle and arc shape, and the sensitivity of vibration transmission can be further reduced.

Specifically, as shown in fig. 2 to 6, the upper projections 12 and the lower projections 13 are staggered in the front-rear direction. This can further disperse the vibration and further improve the vibration damping effect.

More specifically, as shown in fig. 2 to 4, the lower surface of at least one upper protrusion 12 is provided with an upper recess, and the upper surface of at least one lower protrusion 13 is provided with a lower recess. Preferably, the lower surface of each upper protrusion 12 is provided with an upper recess, the upper surface of each lower protrusion 13 is provided with a lower recess, and vulcanized rubber is filled in each upper recess and each lower recess. Therefore, vibration energy transmitted to the position can be attenuated by utilizing the high damping characteristic of the rubber, and the vibration damping effect is further improved.

Advantageously, the upper recess is filled with a first vulcanized rubber 14, the lower recess is filled with a second vulcanized rubber 15, and the first vulcanized rubber 14 and the second vulcanized rubber 15 have different hardness. Therefore, the vibration energy of different frequencies can be specifically attenuated by utilizing the vulcanized rubber with different hardness, so that the vibration damping effect is further improved.

More advantageously, the shore hardness of the first vulcanized rubber 14 is between 40 and 60 degrees and the shore hardness of the second vulcanized rubber 15 is between 60 and 80 degrees. It is preferred that the shore hardness of the first vulcanized rubber 14 is 40 degrees and the shore hardness of the second vulcanized rubber 15 is 55 degrees. Thereby, the hardness of the rubber can be further conveniently controlled, and the vibration damping effect is further improved.

Fig. 3 shows a seat frame front cross member 10 of a vehicle according to one specific example of the present invention. As shown in fig. 3, a mass 16 is embedded in each of the first vulcanized rubber 14 and the second vulcanized rubber 15, and the masses 16 are different in mass. Thus, different masses 16 can be used to form vibration absorbers with different frequencies to damp energy at specific frequencies.

Alternatively, as shown in fig. 3, the plurality of masses 16 may be shaped differently. This further facilitates distinguishing the mass 16, further facilitates the different vibration absorbers to absorb vibrations of different frequencies, and improves the ability of the seat frame front cross member 10 of the vehicle to mitigate vibrations of different frequencies.

Specifically, the seat frame front cross member 10 of the vehicle may be one piece. For example, the seat frame front cross member 10 of the vehicle may be a stamped part. Further, the seat frame front cross member 10 of the vehicle may be punched twice. This can facilitate the manufacture of the seat frame front cross member 10 of the vehicle, and facilitate the improvement of the structural strength and rigidity of the seat frame front cross member 10 of the vehicle.
