Detailed Description

Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

A defrost duct assembly according to an embodiment of the present utility model is described below with reference to fig. 1-4.

The defrosting air duct assembly comprises a body 1, a connecting part 2 and a clamping part 3. The body 1 has a left defrost duct, a central defrost duct, and a right defrost duct arranged in sequence along a first direction. The connecting parts 2 are arranged at intervals along the first direction, the connecting parts 2 are of cylindrical structures with upper ends open, the connecting parts 2 comprise a peripheral wall 21 and a bottom wall 22 connected with the lower end of the peripheral wall 21, a plurality of weakening holes 211 are formed in the peripheral wall 21, and the upper end of the peripheral wall 21 is connected with the body 1. The clamping parts 3 are used for being clamped with the front coaming 4 and corresponding to the connecting parts 2 one by one, and the clamping parts 3 are connected with the bottom walls 22 on the corresponding connecting parts 2.

According to the defrosting air duct assembly provided by the embodiment of the utility model, when an automobile and a pedestrian collide in the front direction and partial acting force is transmitted to the defrosting air duct assembly, the defrosting air duct assembly is more easy to collapse and deform at the peripheral wall 21 of the connecting part 2, so that impact energy is better absorbed, the damage to the head of the pedestrian is reduced, and the safety of the automobile is higher.

The first direction is the left-right direction of the vehicle, and the axial direction of the connecting portion 2 is substantially vertical, and when the connecting portion receives an external force, the connecting portion is deformed by being crushed rearward, so as to absorb impact energy. At this time, the left defrosting air channel, the central defrosting air channel and the right defrosting air channel in the body 1 are sequentially communicated, one end of the left defrosting air channel deviating from the central defrosting air channel and one end of the right defrosting air channel deviating from the central defrosting air channel are both provided with air inlets, and the upper end of the central defrosting air channel is provided with air outlets.

In some embodiments, as shown in fig. 1-4, the body 1, the connecting portion 2, and the clamping portion 3 are integrally injection molded.

The defrosting air duct assembly is integrally injection molded, so that the number of dies is reduced, the development cost is reduced, and the assembly difficulty of the defrosting air duct assembly on a vehicle body is also reduced.

In some embodiments, the weakening holes 211 extend in an axial direction of the peripheral wall 21, and the plurality of weakening holes 211 are arranged at intervals in a circumferential direction of the peripheral wall 21.

Therefore, the peripheral wall 21 of the connecting part 2 is easier to bend and deform when receiving the acting force along the radial direction of the peripheral wall 21, so that the whole connecting part 2 is horizontally bent and deformed, the collapse of the connecting part 2 is realized, and the effective absorption of impact energy is ensured.

Specifically, as shown in fig. 3, the outer contour of the cross section of the peripheral wall 21 is substantially square, that is, the peripheral wall 21 substantially includes four side walls that are connected in sequence and are orthogonal to each other, wherein the weakened holes 211 are four and are respectively provided on the four side walls.

In some embodiments, as shown in fig. 3 and 4, the length of the weakened hole 211 is equal to the dimension of the peripheral wall 21 in the axial direction.

At this time, the plurality of weakening holes 211 substantially completely divide the peripheral wall 21 to form a plurality of independent side walls, and the divided side walls are more likely to be bent and deformed independently, thereby better absorbing impact energy and effectively ensuring the safety of the automobile.

In some embodiments, the thickness of the peripheral wall 21 is 1.8mm-2.2mm and the thickness of the bottom wall 22 is 0.7mm-1.3mm.

Namely, the thickness of the peripheral wall 21 of the connecting part 2 is consistent with the thickness of the wall of the conventional defrosting air duct assembly, the thickness of the bottom wall 22 is approximately half of the conventional thickness, namely, the bottom wall 22 is thinned, when the connecting part 2 is impacted by the outside, the bottom wall 22 is easy to deform and crack, and the clamping part 3 is further collapsed into the peripheral wall 21, so that the connecting part 2 can absorb more impact energy from the axial direction of the peripheral wall 21, and the damage to the head of a pedestrian is further reduced.

Specifically, the thickness of the peripheral wall 21 may be 1.8mm, 2mm, and 2.2mm, and the thickness of the bottom wall 22 may be 0.7mm, 1mm, and 1.3mm.

In some embodiments, the projection of the engagement portion 3 coincides with the projection of the bottom wall 22 on a projection plane perpendicular to the axial direction of the peripheral wall 21.

Therefore, when the bottom wall 22 of the connecting part 2 is deformed and broken due to external impact, the peripheral wall 21 of the connecting part 2 can be downwards moved and sleeved on the clamping part 3, so that the phenomenon that the clamping part 3 interferes with the peripheral wall 21 to cause incomplete collapse is effectively avoided, and the injury to pedestrian collision is further reduced.

In some embodiments, as shown in fig. 4, the body 1 includes a front cover plate 11 located in the middle and opposite to the dash panel 4, and a plurality of thinning grooves 111 are provided on the front cover plate 11.

Namely, when the defrosting air duct assembly is subjected to external impact, the front cover plate 11 in the defrosting air duct assembly can be broken and contracted at the thinning groove 111 so as to further absorb impact energy, thereby reducing the damage to the head of a pedestrian and further improving the safety of an automobile. In addition, the design that the thinning groove 111 is arranged on the front cover plate 11 instead of the weakening hole 211 effectively avoids the influence on the mode and the durability of the instrument panel caused by the too low strength of the front cover plate 11.

In some embodiments, as shown in fig. 4, a plurality of thinning grooves 111 are spaced apart in the first direction, the plurality of thinning grooves 111 extend in the height direction of the front cover plate 11, and at least one thinning groove 111 includes at least two sections of dividing grooves 1111 spaced apart in the height direction.

Namely, the thinning groove 111 extends along the height direction, at this time, the structural strength of the front cover plate 11 in the height direction is relatively higher, so that the mode of the defrosting air duct assembly is ensured, and meanwhile, the front cover plate 11 can be cracked at the thinning groove 111 to absorb more impact energy when being impacted from the horizontal direction, so that the safety of an automobile is ensured.

Specifically, as shown in fig. 4, a plurality of thinning grooves 111 are provided on the outer side surface of the front cover plate 11, except that a part of the thinning grooves 111 includes two divided grooves 1111 arranged at intervals, and the length of the rest of the thinning grooves 111 is substantially equal to the dimension of the front cover plate 11 in the height direction.

In some embodiments, the width of the thinning groove 111 is 0.8mm to 1.2mm, the thickness of the front cover plate 11 at the thinning groove 111 is 0.7mm to 1.3mm, and the thickness of the front cover plate 11 at the portion other than the thinning groove 111 is 1.8mm to 2.2mm.

Therefore, the arrangement of the thinning groove 111 ensures that the front cover plate 11 is easy to collapse and deform to absorb energy impact, and simultaneously further ensures the structural strength of the front cover plate 11, thereby ensuring the mode and durability of the instrument panel.

Specifically, the width of the thinning groove 111 may be 0.8mm, 1mm, and 1.2mm, the thickness of the front cover plate 11 at the thinning groove 111 may be 0.7mm, 1mm, and 1.3mm, and the thicknesses at the remaining positions of the front cover plate 11 are 1.8mm, 2mm, and 2.2mm.
