Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a lifting roof inner panel and a vehicle. Background Technology

[0002] A pop-up roof is a device that allows a vehicle to change its roof height or position, thereby increasing roof space. It is commonly found in convertibles, some commercial vehicles, and specially modified vehicles. To facilitate its raising and lowering, pop-up roofs are typically designed to be lightweight, but this reduces their overall rigidity, making them unreliable for supporting snow loads or assembling components. Utility Model Content

[0012] In some embodiments, the first forked rib includes any one of a Y-shaped rib, an X-shaped rib, and a rice-shaped rib.

[0013] In some embodiments, the reinforcing rib group includes two strip ribs and two sets of second forked ribs. The two strip ribs are arranged at intervals along the width direction of the inner plate. One set of second forked ribs is located on the side of one strip rib away from the other strip rib, and the other set of second forked ribs is located on the side of the other strip rib away from the first strip rib. Each set of second forked ribs includes two second forked ribs, which are respectively adjacent to both ends of the strip rib.

[0015] In some embodiments, the annular rib defines a second groove, the width of which is S, wherein S ≥ 35 mm.

[0016] In some embodiments, the inner plate is provided with a through hole, which includes at least one of a weight reduction hole, a locking hole, and a screw hole.

[0017] In some embodiments, the connecting flange is bent relative to the inner plate, the connecting flange extends circumferentially along the inner plate and is connected end to end, and the outer peripheral surface of the connecting flange is used to connect with the outer plate of the lifting top cover.

[0018] In some embodiments, the distance between the upper and lower edges of the outer peripheral surface of the connecting flange is a, and the outward tilt angle of the outer peripheral surface of the connecting flange is b, wherein a≥9mm and b≤3°.

[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following is combined with Figures 1-3 Description of the inner plate of the lifting top cover according to an embodiment of the present utility model.

[0028] The inner panel of the lifting roof in this embodiment of the utility model includes an inner panel body 1, a reinforcing rib assembly, and a connecting flange 2. The reinforcing rib assembly is disposed in the inner panel body 1, and the reinforcing rib assembly includes at least one of strip ribs 3, annular ribs 6, and forked ribs. The connecting flange 2 is disposed at the edge of the inner panel body 1 and is used to connect with the outer panel of the lifting roof.

[0029] According to the embodiment of this utility model, the inner plate of the lifting roof is provided with at least one of strip ribs 3, annular ribs 6, and forked ribs to effectively improve the rigidity of the inner plate 1. Moreover, the inner plate 1 is connected to the outer plate of the lifting roof by the connecting flange 2 located at its edge, which effectively avoids stress concentration in some areas of the inner plate 1 caused by direct connection between the inner plate 1 and the outer plate. This effectively prevents some areas of the inner plate 1 from prematurely collapsing and deforming under pressure, resulting in higher rigidity of the inner plate 1 and more reliably meeting the support requirements for snow pressure, parts assembly, etc.

[0030] It should be noted that the connecting flange 2, the inner plate 1 and the reinforcing rib assembly are integrally stamped and formed. The reinforcing rib assembly protrudes from the lower surface of the inner plate 1 and defines an upward-facing groove.

[0031] In some embodiments, the reinforcing rib group includes at least two strip ribs 3, which extend along the length direction of the inner plate 1 and are spaced apart along the width direction of the inner plate 1.

[0032] The setting of at least two strip ribs 3 effectively improves the bending strength of the inner plate 1 in the length direction. When the inner plate 1 is subjected to pressure from the upper and lower directions, the two ends of the inner plate 1 are less likely to warp relative to the middle in the length direction, and the support reliability of the inner plate 1 is high.

[0033] For example, such as Figure 1 As shown, there are two strip ribs 3 arranged symmetrically in mirror image to the center of the inner plate 1. The two ends of the strip ribs 3 are adjacent to the two opposite edges of the inner plate 1 in the length direction. The two strip ribs 3 divide the inner plate 1 into three parts arranged sequentially along its width direction and with approximately equal width.

[0034] In some embodiments, the stiffener group further includes at least two first forked ribs 4, which are located between any two adjacent strip ribs 3, and the at least two first forked ribs 4 are arranged along the length direction of the plate.

[0035] The first forked rib 4 makes the inner plate 1 less prone to warping relative to the middle at the opposite ends in the length direction and the opposite ends in the width direction when it is subjected to pressure from the top and bottom directions. The inner plate 1 has stronger rigidity and can withstand greater pressure from the top and bottom directions without deformation.

[0036] For example, the first forked rib 4 includes at least two intersecting strip-shaped protrusions, such as... Figure 1 As shown, the first forked rib 4 includes two intersecting strip-shaped protrusions, which are also known as X-shaped ribs.

[0037] In some embodiments, the first forked rib 4 defines a first groove, and at least two adjacent first grooves are connected to each other.

[0038] That is, at least one strip protrusion of the first forked rib 4 is connected to at least one strip protrusion of the adjacent first forked rib 4, thereby further improving the bending strength of the inner plate 1 and making the support reliability of the inner plate 1 higher.

[0039] For example, such as Figure 1 As shown, there are two first forked ribs 4, both of which are X-shaped ribs. The first groove defined by the first forked ribs 4 is an X-shaped groove including two intersecting strip grooves. The ends of the two strip grooves of the first groove are respectively connected to the ends of the two strip grooves of the other first groove.

[0040] In some embodiments, the first forked rib 4 defines a first groove, the depth of which is L, wherein L≥15mm.

[0041] This makes the sidewall of the first groove formed in the first forked rib 4 sufficiently high, so as to have higher bending strength in the vertical direction, thereby making the inner plate 1 have higher rigidity and better meet the needs of snow pressure and parts assembly.

[0042] For example, such as Figure 2 As shown, the opening of the first groove faces upward, and the depth L of the first groove can be 15mm, 17mm, or 20mm.

[0043] It should be noted that the first forked rib 4 includes any one of Y-shaped ribs, X-shaped ribs and rice-shaped ribs, and the above forked ribs can effectively increase the stiffness of the inner plate 1.

[0044] In some embodiments, the reinforcing rib group includes two strip ribs 3 and two sets of second forked ribs 5. The two strip ribs 3 are arranged at intervals along the width direction of the inner plate 1. One set of second forked ribs 5 is located on the side of one strip rib 3 away from the other strip rib 3, and the other set of second forked ribs 5 is located on the side of another strip rib 3 away from the first strip rib 3. Each set of second forked ribs 5 includes two second forked ribs 5, and the two second forked ribs 5 are respectively adjacent to both ends of the strip rib 3.

[0045] The setting of the second forked rib 5 effectively improves the rigidity of the inner plate 1 in the area near the end of the strip rib 3, and the support reliability in this area is higher. Combined with the arrangement of the strip rib 3, the overall rigidity of the inner plate 1 is further improved.

[0046] For example, such as Figure 1 and Figure 3 As shown, there are four second forked ribs 5 arranged at four corners on the inner plate 1. The four second forked ribs 5 are divided into two groups arranged at intervals along the width direction. The two groups of second forked ribs 5 are located on the opposite side of the two strip ribs 3. Two first forked ribs 4 are also arranged between the two strip ribs 3 along the length direction of the inner plate 1.

[0047] In some embodiments, the reinforcing rib group further includes annular ribs 6, which are arranged around strip ribs 3.

[0048] The arrangement of the ring ribs 6 effectively improves the rigidity near the edge of the inner plate 1. When the connecting flange 2 of the inner plate of the lifting cover is compressed by the outer plate, the edge of the inner plate 1 is less likely to deform, and the overall rigidity of the inner plate of the lifting cover is higher.

[0049] For example, such as Figure 1 and Figure 3 As shown, the annular reinforcement 6 is located near the edge of the inner plate 1, and the annular reinforcement 6 is arranged around the four second forked reinforcements 5.

[0050] In some embodiments, the annular rib 6 defines a second groove, the width of which is S, wherein S≥35mm.

[0051] This allows the annular rib 6 to have a larger distribution area, resulting in higher bending strength in the vertical direction, which in turn gives the inner plate 1 higher rigidity, better meeting the needs of snow pressure and parts assembly.

[0052] For example, the second groove is an annular groove with the opening facing upwards, and the width of the second groove is 35mm, 37mm and 40mm.

[0053] In some embodiments, the inner plate 1 is provided with a through hole, which includes at least one of a weight reduction hole 12, a snap hole, and a screw hole 11.

[0054] By providing screw holes 11 and / or snap holes on the inner plate 1 for assembling parts, the disassembly and replacement of parts are facilitated. By providing weight reduction holes 12 on the inner plate 1, the weight of the inner plate of the lifting top cover is further reduced, resulting in higher lifting efficiency of the lifting top cover assembly.

[0055] For example, such as Figure 1 As shown, the inner plate 1 has multiple weight-reducing holes 12, and the annular rib 6 surrounds the weight-reducing holes 12. The inner plate 1 has multiple locking holes or screw holes 11, which are located on the outer periphery of the annular rib 6.

[0056] In some embodiments, the connecting flange 2 is bent relative to the inner plate 1, the connecting flange 2 extends circumferentially along the inner plate 1 and is connected end to end, and the outer peripheral surface of the connecting flange 2 is used to connect with the outer plate of the lifting top cover.

[0057] That is, the flange face closed loop formed by the connecting flange 2 and connected to the outer surface of the lifting cover is not broken, so that the connecting flange 2 forms a ring rib, which effectively improves the side rigidity of the inner plate of the lifting cover. The overall rigidity of the inner plate of the lifting cover is higher, which can more reliably meet the support requirements of snow pressure, parts assembly, etc.

[0058] For example, the connecting flange 2 is bent downward relative to the inner plate 1, and the inner side of the lifting top cover is attached to and welded to the outer peripheral surface of the connecting flange 2.

[0059] In some embodiments, the distance between the upper edge and the lower edge of the outer peripheral surface of the connecting flange 2 is a, and the outward tilt angle of the outer peripheral surface of the connecting flange 2 is b, wherein a≥9mm and b≤3°.

[0060] By setting the width of the connecting flange 2 to be greater than or equal to 9mm, a larger welding area is provided between it and the outer panel of the lifting cover, resulting in a stronger connection. By setting the inclination angle of the outer circumference of the connecting flange 2 to be less than or equal to 3°, the bending strength of the connecting flange 2 in the vertical direction is further improved. After the connecting flange 2 is connected to the outer panel of the lifting cover, the inner panel of the lifting cover is less prone to deformation at the connecting flange 2.

[0061] For example, the width of the connecting flange 2 can be 9mm, 11mm and 13mm, and the inclination angle of the outer peripheral surface of the connecting flange 2 can be 1°, 2° and 3°.

[0062] The vehicle according to the present invention includes a liftable roof inner panel as described in any of the above embodiments.
