[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0024] Combine the following Figure 1 and Figure 2 A luggage compartment floor according to an embodiment of the present invention is described.
[0025] The luggage compartment floor of the embodiment of the utility model includes a support plate 1 and a flange, which are stamped and formed as a whole. A stamped transverse rib 13 extending along a first direction is stamped on the support plate 1, and both ends of the stamped transverse rib 13 extend to two opposite edges of the support plate 1 along the first direction respectively. The flange is located at the edge of the support plate 1 and is used to be connected to the frame of the vehicle.
[0026] According to the luggage compartment floor of the embodiment of the utility model, the support plate 1 is connected to the vehicle frame through the flange, and the support plate 1 is stamped with a stamped transverse rib 13, and the two ends of the stamped transverse rib 13 extend to the two opposite edges of the support plate 1 along the first direction, thereby making the support plate 1 have a higher lateral bearing strength at any position in the first direction. At the same time, the direct stamping design of the stamped transverse rib 13 on the support plate 1, and the integral stamping design of the support plate 1 and the flange, make the manufacturing process of the luggage compartment floor simple, and the number of process equipment required is small, thereby reducing the manufacturing cost of the luggage compartment floor and improving the assembly efficiency of the vehicle body.
[0027] It should be noted that the support plate 1 is the main part of the trunk floor, and the flange is connected to the crossbeam and longitudinal beam on the frame by welding or riveting. The first direction is the width direction of the trunk floor, which is also the left-right direction of the vehicle, and the length of the stamped transverse rib 13 is substantially equal to the width of the support plate 1.
[0028] For ease of understanding, Figure 2 The direction indicated by the middle arrow A is the first direction of the luggage compartment floor according to the embodiment of the utility model. Figure 2The direction indicated by the middle arrow B is the second direction of the luggage compartment floor according to the embodiment of the present utility model.
[0029] In some embodiments, Figure 1 and Figure 2 As shown, the support plate 1 is stamped with stamped longitudinal ribs extending along the second direction, the second direction is perpendicular to the first direction, and the stamped longitudinal ribs are connected to the stamped transverse ribs 13 .
[0030] The design of the stamped longitudinal ribs effectively improves the longitudinal bearing strength of the support plate 1, thereby effectively improving the stiffness and mode of the support plate 1, effectively reducing the noise transmitted from the chassis to the vehicle body, and improving the comfort of the vehicle. At the same time, the stamped longitudinal ribs are formed by stamping rather than welding on the support plate 1, which effectively simplifies the production steps of the trunk floor and improves the welding and assembly efficiency of the vehicle body.
[0031] Specifically, the second direction is the length direction of the support plate 1, which is also the front-rear direction of the vehicle. The stamped longitudinal ribs and the stamped transverse ribs 13 are both formed by stamping the support plate 1 from bottom to top, and the bottom surface of the support plate 1 forms a first groove opposite to the stamped longitudinal ribs and a second groove opposite to the stamped transverse ribs 13, and the first groove and the second groove are connected.
[0032] In some embodiments, Figure 1 and Figure 2 As shown, the stamped longitudinal ribs include a plurality of first longitudinal ribs 14 located on a side of the stamped transverse rib 13 facing the middle cross beam of the vehicle frame, and the plurality of first longitudinal ribs 14 are arranged at intervals along a first direction.
[0033] The multiple first longitudinal ribs 14 are arranged in an interval arrangement along the first direction, so that the support plate 1 has good longitudinal bearing strength at each position in the first direction, and the support plate 1 has better stiffness and mode at the side of the stamped transverse rib 13 facing the middle cross beam.
[0034] Specifically, the number of the stamped transverse rib 13 is one, and the stamped transverse rib 13 is adjacent to the rear end of the support plate 1, thereby greatly improving the lateral stiffness of the rear subframe mounting point, which is beneficial to NVH (abbreviation of noise, vibration and harshness) and vehicle handling performance.
[0035] In some embodiments, Figure 1 and Figure 2 As shown, the stamped longitudinal ribs further include a plurality of second longitudinal ribs 15 located on the side of the stamped transverse rib 13 facing the rear cross beam of the vehicle frame, and the plurality of second longitudinal ribs 15 are arranged at intervals along the first direction.
[0036] The arrangement of multiple second longitudinal ribs 15 spaced apart along the first direction makes the longitudinal bearing strength of the support plate 1 at each position in the first direction more uniform, and the stiffness and mode of the support plate 1 on the side of the stamped transverse rib 13 facing the rear cross beam are better.
[0037] Specifically, a plurality of second longitudinal ribs 15 are arranged at equal intervals along the first direction, and one end of the second longitudinal rib 15 away from the stamped transverse rib 13 is adjacent to the edge of the support plate 1 .
[0038] For example, the number of the first longitudinal ribs 14 is four, the number of the second longitudinal ribs 15 is three, and the four first longitudinal ribs 14 and the three second longitudinal ribs 15 are arranged alternately along the first direction.
[0039] In some embodiments, the flange includes a first flange 2 and a second flange 3 respectively arranged on both sides of the support plate 1 along the second direction, the first flange 2 is used to connect to the middle cross beam of the frame, and the second flange 3 is used to connect to the rear cross beam of the frame. The support plate 1 includes a first plate 11 and a second plate 12 connected along the second direction, the first plate 11 is connected to the first flange 2, the second plate 12 is connected to the second flange 3, and the first plate 11 is bent downward relative to the second plate 12.
[0040] The second plate 12 can be arranged substantially horizontally. In this case, the design of the first plate 11 bending downward relative to the second plate 12 ensures that the first flange 2 and the second flange 3 are connected to the middle cross beam and the rear cross beam respectively, and makes the second plate 12 higher. More space for installing equipment such as power supply machines can be reserved under the second plate 12, thereby improving the space utilization rate at the bottom of the second plate 12. At the same time, the cross-sectional characteristics of the connection between the second plate 12 and the first plate 11 can effectively meet the load transfer requirements.
[0041] Specifically, the distribution area of the first plate 11 is much smaller than that of the second plate 12. The first plate 11 is bent downward mainly to connect with the side wall of the middle cross beam, and the second plate 12 provides support for the bottom of the luggage compartment and connects and strengthens the rear end frame of the vehicle frame. The angle between the first plate 11 and the second plate 12 can be 40°, 45°, and 50°.
[0042] In some embodiments, the stamped transverse ribs 13 are arranged on the second plate 12 , along the first direction, the first longitudinal ribs 14 located at the edge are arranged on the second plate 12 , and the first longitudinal ribs 14 located in the middle part are arranged on the first plate 11 and the second plate 12 .
[0043] The rigidity of the two side portions of the support plate 1 in the first direction is greater than that of the middle portion. By arranging the first longitudinal ribs 14 that span the first plate 11 and the second plate 12 in the middle portion, the structural strength of the support plate 1 in the middle portion is effectively strengthened. The first longitudinal ribs 14 located at the edge are only arranged on the second plate 12, thereby also improving the structural strength of the two side portions of the support plate 1, and also reducing the total weight of the first longitudinal ribs 14, and the manufacturing cost of the luggage compartment floor is lower.
[0044] Specifically, Figure 1 and Figure 2 The ends of the two first longitudinal ribs 14 at the two edges that are away from the stamped transverse rib 13 extend to the junction of the first plate 11 and the second plate 12, and the ends of the first longitudinal rib 14 at the middle position that are away from the stamped transverse rib 13 extend to the center position of the first plate 11 in the second direction.
[0045] In some embodiments, a plurality of first longitudinal ribs 14 separate the support plate 1 into a plurality of support areas 19 spaced apart along the first direction, and at least one support area 19 is stamped with at least one of an H-shaped rib 16, a Y-shaped rib 17 and an L-shaped rib 18.
[0046] Based on the limited area of the support area 19, the design of at least one of the H-shaped ribs 16, the Y-shaped ribs 17 and the L-shaped ribs 18 further reduces the plane area of the support plate 1, effectively reduces the radiated sound power in the frequency range of 200Hz-500Hz, effectively reduces the noise outside the vehicle transmitted to the inside of the vehicle through radiation, and improves the NVH performance.
[0047] In some embodiments, Figure 1 and Figure 2 As shown, the number of first longitudinal ribs 14 is at least three, the number of support areas 19 is at least four, at least two support areas 19 are stamped with L-shaped ribs 18, and at least two support areas 19 are stamped with H-shaped ribs 16 and Y-shaped ribs 17 arranged at intervals along the second direction.
[0048] The design of at least three first longitudinal ribs 14 effectively ensures the longitudinal bearing strength of the support plate 1. At the same time, no stamping ribs are provided for the support area 19 with a smaller area, L-shaped ribs 18 are provided for the support area 19 with a medium area, and H-shaped ribs 16 and Y-shaped ribs 17 are provided for the support area 19 with a larger area, which effectively reduces the horizontal plate distribution area in the support plate 1 and effectively improves the stiffness and mode of the luggage compartment floor.
[0049] For example, the support plate 1 is symmetrically arranged on the left and right, the number of the first longitudinal ribs 14 is four, the number of the support areas 19 is five, the two support areas 19 located at the edges are both stamped with L-shaped ribs 18, the support areas 19 adjacent to the edge support areas 19 are stamped with H-shaped ribs 16 and Y-shaped ribs 17 arranged at intervals, and the support area 19 located in the middle is not provided with stamped ribs.
[0050] In addition, the L-shaped ribs 18 span the first plate 11 and the second plate 12 , the H-shaped ribs 16 are provided on the second plate 12 , and the Y-shaped ribs 17 span the first plate 11 and the second plate 12 .
[0051] In some embodiments, Figure 1 and Figure 2 As shown, the flanges also include a third flange 4 and a fourth flange 5 respectively arranged on both sides of the support plate 1 along the first direction, and the third flange 4 and the fourth flange 5 are both used to connect with the rear longitudinal beam of the frame. The third flange 4 and the fourth flange 5 are mainly used to connect with the rear longitudinal beam of the frame, and there is no need to stamp and form stamping ribs thereon to ensure the connection strength with the rear longitudinal beam.
[0052] like Figure 1 As shown, the first flange 2 , the third flange 4 , the second flange 3 and the fourth flange 5 are connected end to end and surround the support plate 1 .
