Example 1

The present embodiment relates to a base skeleton of a front seat, which can improve the overall structural stability of the base skeleton 4 of the front seat; an exemplary configuration of which is shown in fig. 1 and 2.

In general, the base frame of the front seat includes base side beams 40 symmetrically disposed on the left and right sides of the base frame 4, and a base reinforcing beam 41 connected between the front ends of the two base side beams 40. Wherein the base reinforcing beam 41 includes a base plate 410, and a flange 411 formed at a front side edge portion 4101 and an end edge 4103 of the base plate 410; wherein, two ends of the base plate 410 are respectively overlapped on the corresponding side of the base side beams 40, that is, the base plate 410 is connected between the front ends of the base side beams 40 on the left and right sides, and an upward convex or downward concave reinforcing structure is formed on the base plate 410.

Specifically, as shown in fig. 3, the flange 411 of the present embodiment is formed by bending downward the base frame 4, and preferably, the height H of the flange 411 is 30mm to 40mm; for example, 30mm, 35mm, 40mm, etc. can be used. The flange 411 can improve the overall structural strength of the base reinforcing beam 41, and further improve the local structural strength of the base skeleton 4, so as to provide support for the increase of the overall structural strength of the front seat and the reduction of the sensitivity to vibration response. The turned edge 411 is downwards bent and formed, so that the seat cushion is conveniently paved on the base framework 4; the height of the flange 411 is set between 30mm and 40mm, so that the base portion of the front seat can have a reasonable thickness dimension while the structural reinforcing effect of the flange 411 is ensured.

As shown in fig. 2 and 4, in the present embodiment, the rear side portion 4102 and the front side portion 4101 of the base plate 410 each have an arch shape that arches toward the front of the front seat. The rear side 4102 and the front side 4101 of the base 410 are designed to be arched forward, so that the overall structural strength of the base reinforcing beam 41 can be improved, and the influence of external vibration excitation on the front seat can be attenuated by virtue of the energy absorption and vibration reduction characteristics of the arch structure, thereby improving the structural stability of the base skeleton 4 and the riding comfort of the front seat. The arch structure has curved transitions at the corner portions of the front side edge 4101 and the end edge 4103 of the base reinforcement beam 41, and is also advantageous for reinforcing the structural strength at the transition junctions on both sides of the base reinforcement beam 41.

There are, of course, a variety of different arrangements for the placement of the reinforcing structures on the substrate 410. In the present embodiment, as shown in fig. 2 and 4, the reinforcing structure includes a first protrusion 4121 provided along the front side edge portion 4101 in an elongated shape, the first protrusion 4121 having a width T of 10mm to 15mm; for example, 10mm, 12mm, 14mm, etc. can be used. The protrusion height of the first protrusion 4121 is preferably set to 6mm. The elongated first protrusions 4121 are provided along the front side edge portion 4101, which effectively improves the structural strength of the front side edge portion 4101 of the base reinforcement beam 41, thereby providing reliable support for the thigh portion of the human body.

Based on the above arrangement, the reinforcing structure further includes a plurality of first grooves 4131 spaced on the first protrusions 4121, each of the first grooves 4131 is elliptical and perpendicular to the first protrusions 4121, and extends from the top of the first protrusions 4121 to the flange 411. In the present embodiment, three first grooves 4131 are uniformly distributed on the first protrusion 4121 at intervals, one first groove 4131 is disposed in the middle of the first protrusion 4121, and two first grooves 4131 are symmetrically disposed on the left and right sides of the first groove 4131. The first grooves 4131 are formed on the first protrusion 4121 at intervals, so that the structural strength of the front side portion 4101 of the substrate 410 can be further improved.

In addition, the substrate 410 of the present embodiment includes a supporting portion 410a located between the two base side beams 40, and overlapping portions 410b respectively disposed at two ends of the supporting portion 410 a; the bridging portion 410b is connected to the base side rail 40 on the corresponding side, and the receiver portion 410a is disposed to be recessed with respect to the bridging portion 410 b. The substrate 410 is designed into a concave arch structure, so that the overall structural strength of the base reinforcing beam 41 can be effectively enhanced; the overlap portion 410b is higher than the support portion 410a, so as to facilitate the improvement of the wrapping property of the seat base portion on the buttocks of the human body.

The reinforcement structure further includes second protrusions 4122 and third protrusions 4123 disposed on the bearing portion 410a along the length direction of the base reinforcement beam 41, based on the disposition of the bearing portion 410a and the overlap portion 410b; meanwhile, a plurality of elongated fourth protrusions 4124 are included, which are obliquely disposed at the connection portion of the supporting portion 410a and the overlap portion 410 b.

Specifically, the second protrusion 4122 is disposed in the middle of the supporting portion 410a and has a long strip shape; the design width is 30mm, the height of the bulge is 8mm, and the length is 314mm; the structural strength of the middle portion of the base reinforcing beam 41 can be enhanced by providing the second protrusions 4122.

The third protrusion 4123 is provided near the rear side edge portion 4102 of the substrate 410, and takes a long strip shape; the height of the designed bulge is 20mm, and the length of the designed bulge is 335mm, so that the structural strength of the rear part of the base reinforcing beam 41 is improved, and the sensitivity of the base reinforcing beam 41 to vibration response is reduced.

The four protrusions 4124 are six, three protrusions are respectively arranged at two ends of the bearing portion 410a at intervals, and the heights of the protrusions are 5mm, so that the structural strength of the weak part of the transition part of the bearing portion 410a and the lap joint portion 410b is improved, and the connection stability between the base reinforcing beam 41 and the base side beam 40 is improved. The second protrusion 4122 and the third protrusion 4123 provided on the support portion 410a can provide a significant reinforcing effect on the structural strength of the support portion 410a in both the length and width directions.

In addition, the reinforcing structure further includes a plurality of second grooves 4132 formed on the supporting portion 410a at intervals, and a third groove 4133 formed on the overlapping portion 410 b. Wherein each second groove 4132 is disposed intersecting the second protrusion 4122. A through hole is formed in the bottom of the third groove 4133, and the overlap portion 410b is connected to the base side rail 40 by a bolt 414 passing through the through hole formed in the bottom of the third groove 4133.

Specifically, in the present embodiment, the second grooves 4132 are two rectangular grooves symmetrically disposed about the center line of the base frame 4, and the second protrusions 4122 penetrate the two second grooves 4132. The third groove 4133 was designed to have a width of 51mm, a length of 78mm and a depth of 11mm. The second groove 4132 may further improve the structural strength of the middle portion of the base reinforcing beam 41, and reduce the sensitivity of the base reinforcing beam 41 to vibration response.

The second groove 4132 is disposed on the supporting portion 410a, and the structural strength of the middle portion of the substrate 410 can be greatly improved by the cross-matching between the second groove 4132 and the second protrusion 4122. By providing the third groove 4133 on the lap portion 410b, not only the structural strength of the lap portion 410b itself can be enhanced, but also a good condition can be provided for the mounting arrangement of the bolts 414, preventing the heads of the bolts 414 from protruding to easily puncture the seat cushion of the front seat.

In summary, in the base skeleton of the front seat of the present embodiment, the base reinforcing beam 41 is disposed between the front ends of the base side beams 40 on both sides, and the structural strength of the base reinforcing beam 41 itself can be effectively improved by using the flange 411 at the edge of the base plate 410 of the base reinforcing beam 41 and the reinforcing structure formed on the base plate 410; by connecting the base reinforcing cross members 41 between the base side members 40 on both sides, the structural performance of the front portion of the base frame 4 can be effectively enhanced, thereby improving the overall structural stability of the base frame 4 of the front seat.
