Description

Technical Field

[0001] The present application relates to the technical field of rear enclosure structures, and in particular to a rear enclosure assembly structure and a vehicle. Background Art

[0002] Since the rear outer panel is set at a higher height and the rear bumper mounting bracket is set at a lower height, the Z-direction (vehicle height direction) dimension of the rear outer panel is usually extended to enable the rear outer panel to provide a welding surface for the rear bumper mounting bracket. In this way, the area of ​​the rear outer panel is greatly increased. When the thickness of the rear outer panel along the X-direction (vehicle length direction, that is, the thickness direction of the rear outer panel) remains unchanged, the overall stiffness of the rear outer panel will become smaller, which will cause the rear outer panel to be easily deformed during transportation, and then cause the mounting holes of the rear outer panel to be easily offset, affecting the assembly of the entire rear outer panel assembly.

DETAILED DESCRIPTION

[0024] Since the rear outer panel is set at a higher height and the rear bumper mounting bracket is set at a lower height, the Z-direction (vehicle height direction) dimension of the rear outer panel is usually extended to enable the rear outer panel to provide a welding surface for the rear bumper mounting bracket. In this way, the area of ​​the rear outer panel is greatly increased. When the thickness of the rear outer panel along the X-direction (vehicle length direction, that is, the thickness direction of the rear outer panel) remains unchanged, the overall stiffness of the rear outer panel will become smaller, which will cause the rear outer panel to be easily deformed during transportation, and then cause the mounting holes of the rear outer panel to be easily offset, affecting the assembly of the entire rear outer panel assembly.

[0025] See also Figure 1-Figure 3 In order to solve the problem that the existing rear enclosure outer panel has a large Z-direction dimension resulting in a decrease in stiffness, the present application provides a rear enclosure assembly structure and a vehicle, which rear enclosure assembly structure includes a rear enclosure outer panel 100, a rear enclosure inner panel 200, a rear anti-collision beam mounting back panel 300 and a rear bumper mounting bracket 400. The rear enclosure outer panel 100 and the rear enclosure inner panel 200 are arranged opposite to each other and connected. One end of the rear anti-collision beam mounting back panel 300 is clamped between the rear enclosure outer panel 100 and the rear enclosure inner panel 200 and is respectively connected to the rear enclosure outer panel 100 and the rear enclosure inner panel 200. The other end of the rear anti-collision beam mounting back panel 300 is connected to the rear bumper mounting bracket 400.

[0026] In the rear enclosure assembly structure of the present application, there is no need to extend the rear enclosure outer panel 100 along the vehicle height direction and connect it to the rear bumper mounting bracket 400. Instead, the rear anti-collision beam mounting back panel 300 is set on the rear enclosure assembly structure so that the rear enclosure outer panel 100 is connected to the rear bumper mounting bracket 400 through the rear anti-collision beam mounting back panel 300. Obviously, with such a setting, the size of the rear enclosure outer panel 100 along the vehicle height direction is reduced, thereby increasing the overall stiffness of the rear enclosure outer panel 100 and preventing the rear enclosure outer panel 100 from being easily deformed during transportation, thereby avoiding the displacement of the mounting holes of the rear enclosure assembly structure, thereby improving production efficiency.

[0027] Furthermore, the rear enclosure outer panel 100 and the rear enclosure inner panel 200 are arranged relative to each other and connected, which also increases the assembly rigidity of the rear enclosure outer panel 100 in the rear enclosure assembly structure to a certain extent.

[0028] Specifically, in one embodiment, the maximum length of the rear outer panel 100 along the vehicle height direction is less than or equal to 300 mm. Preferably, the maximum length of the rear outer panel 100 along the vehicle height direction is equal to 228 mm.

[0029] Such an arrangement greatly reduces the length of the rear outer panel 100 along the vehicle height direction, which is beneficial to increasing the rigidity of the rear outer panel 100 without affecting the assembly of the rear outer panel 100 in the rear assembly structure.

[0030] In one embodiment, the thickness of the rear anti-collision beam mounting back plate 300 is greater than or equal to 1.5 mm. Preferably, the thickness of the rear anti-collision beam mounting back plate 300 is 2 mm, and the rear anti-collision beam mounting back plate 300 is formed by processing high-strength steel, which further improves the structural strength of the rear anti-collision beam mounting back plate 300 and can effectively improve the rigidity of the entire rear enclosure assembly structure.

[0031] In one embodiment, if Figure 1 As shown, the length A of the rear bumper mounting bracket 400 protruding from the end of the rear anti-collision beam mounting back plate 300 in the direction away from the rear outer panel 100 satisfies 200mm≤A≤400mm. Preferably, A is 290mm.

[0032] With this arrangement, on the one hand, A is greater than or equal to 200 mm, which can meet the assembly and styling requirements of the rear bumper and the rear bumper mounting bracket 400 ; on the other hand, A is less than or equal to 400 mm, which can increase the structural rigidity of the rear bumper mounting bracket 400 .

[0033] Furthermore, through a large number of tests, it can be seen that the present application improves the stiffness of the rear bumper mounting bracket 400 from less than 10 N / mm to 18 N / mm.

[0034] In one embodiment, the rear anti-collision beam mounting back plate 300 , the rear enclosure outer plate 100 and the rear enclosure inner plate 200 may be welded, or may be screwed together by fasteners.

[0035] This is beneficial to improving the connection strength between the rear anti-collision beam mounting back plate 300, the rear enclosure outer panel 100 and the rear enclosure inner panel 200.

[0036] In one embodiment, the rear anti-collision beam mounting back plate 300 and the rear bumper mounting bracket 400 may be welded, or may be screwed together by fasteners.

[0037] This is beneficial to improving the connection strength between the rear anti-collision beam mounting back plate 300 and the rear bumper mounting bracket 400 .

[0038] In one embodiment, the rear wall inner panel 200 and the rear wall outer panel 100 are arranged along the front-rear direction of the vehicle, and the rear wall inner panel 200 and the rear wall outer panel 100 are arranged to form a structural cavity (not shown).

[0039] Such an arrangement can significantly increase the assembly strength and anti-bending performance of the rear enclosure inner panel 200 and the rear enclosure outer panel 100, and prevent the rear enclosure assembly structure from bending in the vehicle width direction (Y direction).

[0040] Specifically, in one embodiment, the rear enclosure inner panel 200 is provided with a first structural groove that is recessed in a direction away from the rear enclosure outer panel 100, and the rear enclosure outer panel 100 and the first structural groove cooperate to form a structural cavity, or the rear enclosure outer panel 100 is provided with a second structural groove that is recessed in a direction away from the rear enclosure inner panel 200, and the rear enclosure inner panel 200 and the second structural groove cooperate to form a structural cavity that protrudes along the length direction of the vehicle.

[0041] With such an arrangement, the first structural groove and the second structural groove can be processed by stamping or integral casting, which reduces the processing difficulty of the structural cavity.

[0042] In another embodiment, the first structural groove and the second structural groove may be arranged opposite to each other and cooperate to form a structural cavity.

[0043] In yet another embodiment, Figure 1 and Figure 2 As shown, the rear inner panel 200 is bent at both ends along the vehicle height direction and around the vehicle width direction to form a first inner panel 210 and a second inner panel 220. The first inner panel 210 and the second inner panel 220 are arranged at an angle. In other words, the rear inner panel 200 is bent to form an L-shaped or approximately L-shaped cross-section, similar to angle steel. Specifically, the angle between the first inner panel 210 and the second inner panel 220 is between 70 and 120 degrees.

[0044] The rear outer panel 100 is bent at both ends along the vehicle height direction and around the vehicle width direction to form a first outer panel 110 and a second outer panel 120. The first outer panel 110 and the second outer panel 120 are arranged at an angle. In other words, the rear outer panel 100 is bent to form an L-shaped or approximately L-shaped cross-section, similar to angle steel. Specifically, the angle between the first outer panel 110 and the second outer panel 120 is between 70 and 120 degrees.

[0045] Furthermore, the first inner panel 210 is connected to the first outer panel 110 , and the second inner panel 220 is connected to the second outer panel 120 , so that the rear enclosure inner panel 200 and the rear enclosure outer panel 100 are arranged to form a structural cavity.

[0046] By bending the rear quarter inner panel 200 and the rear quarter outer panel 100, their strength is greatly increased, thereby effectively improving the structural strength of the entire rear quarter assembly. Furthermore, the first inner panel 210 and the second inner panel 220 can be manufactured through stamping or integral casting, reducing the difficulty of manufacturing the rear quarter inner panel 200. Similarly, the first outer panel 110 and the second outer panel 120 can be manufactured through stamping or integral casting, reducing the difficulty of manufacturing the rear quarter outer panel 100.

[0047] In one embodiment, if Figure 3As shown, along the direction from the rear outer panel 100 to the rear bumper mounting bracket 400 (that is, the vehicle height direction), the rear anti-collision beam mounting back plate 300 includes a first connecting section 310, a second connecting section 320, an extension section 330 and a third connecting section 340 connected in sequence, the rear anti-collision beam mounting back plate 300 is clamped and connected between the rear outer panel 100 and the rear inner panel 200 through the first connecting section 310, the rear anti-collision beam mounting back plate 300 is connected to the rear inner panel 200 through the second connecting section 320, and the rear inner panel 200 is clamped and connected between the second connecting section 320 and the rear floor of the vehicle (not shown), the rear anti-collision beam mounting back plate 300 is connected to the rear bumper mounting bracket 400 through the third connecting section 340, and the extension section 330 is used to extend the length of the rear anti-collision beam mounting back plate 300 along the vehicle height direction.

[0048] Specifically, the lengths of the first connecting section 310, the second connecting section 320 and the extension section 330 along the vehicle width direction are greater than the length of the third connecting section 340 along the vehicle width direction, that is, the first connecting section 310, the second connecting section 320 and the extension section 330 are relatively wide, and the third connecting section 340 is relatively narrow, so that the rear anti-collision beam mounting back plate 300 is overall axe-shaped.

[0049] From the above, it can be seen that the rear outer panel 100, the first connecting section 310 and the rear inner panel 200 are connected to form a three-layer panel structure, the second connecting section 320, the rear inner panel 200 and the rear floor are connected to form a three-layer panel structure, and the rear bumper mounting bracket 400 and the third connecting section 340 are connected to form a two-layer panel structure.

[0050] In this way, by forming a multi-layer plate structure in each area, the assembly integration of the rear panel assembly structure can be improved, and the structural strength and rigidity of the rear panel assembly structure can be increased.

[0051] Furthermore, in one embodiment, Figure 3 As shown, along the direction from the rear outer panel 100 to the rear bumper mounting bracket 400, the width M of the first connecting section 310, the width N of the second connecting section 320, and the width W of the third connecting section 340 respectively satisfy 10mm≤M≤20mm, preferably, M is 15mm, 10mm≤N≤20mm, preferably, N is 15mm, 20mm≤W≤100mm, preferably, W is 47mm.

[0052] Such an arrangement can reduce the total length of the rear anti-collision beam mounting back plate 300 along the vehicle height direction while ensuring the assembly strength, thereby reducing the total length of the rear enclosure assembly structure along the vehicle height direction.

[0053] In one embodiment, if Figure 1 and Figure 2As shown, the number of rear anti-collision beam mounting back plates 300 is two, and the two rear anti-collision beam mounting back plates 300 are respectively connected to the two ends of the rear inner panel 200 and the rear outer panel 100 along the width direction of the vehicle. The number of rear bumper mounting brackets 400 is two, and the two rear bumper mounting brackets 400 are respectively connected to the two ends of the rear inner panel 200 and the rear outer panel 100 along the width direction of the vehicle.

[0054] Such an arrangement is beneficial to improving the assembly stability of the rear panel assembly structure along the vehicle width direction.

[0055] But not limited to this, in other embodiments, the number of rear anti-collision beam mounting back plates 300 can also be three, four or other values, which are not listed here one by one. Similarly, in other embodiments, the number of rear bumper mounting brackets 400 can also be three, four or other values, which are not listed here one by one.
