DETAILED DESCRIPTION
[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0026] Reference below Figure 1-Figure 3 Describing the tailgate 100 of the embodiment of the utility model, the reinforcing plate 2 is close to the connecting portion 4 and the connecting hinge area, which improves the strength of the tailgate 100 while also strengthening the connecting portion 4 and the connecting hinge, thereby improving the reliability of the spare tire being connected to the connecting hinge through the spare tire rack.
[0027] like Figure 1-Figure 3 The tailgate 100 according to the embodiment of the present utility model is described, including: a door body and a reinforcement plate 2.
[0028] Among them, a connecting part 4 is provided on one side of the door body, and the connecting part 4 is used to be connected to the vehicle body and / or the spare tire rack through a connecting hinge, and the door body includes an inner panel 1 and an outer panel 3, and the inner panel 1 and the outer panel 3 are connected along the front and rear directions; the reinforcing plate 2 is installed between the inner panel 1 and the outer panel 3 and is respectively connected to the inner panel 1 and the outer panel 3, and the reinforcing plate 2 is located between the inner panel 1 and the outer panel 3 near the connecting part 4.
[0029] In practice, when the connecting part 4 of the door body is connected to the vehicle body or the spare tire rack through a connecting hinge, the connecting hinge can enable the door body to rotate and open relative to the vehicle body, and at the same time, one end of the spare tire rack is also connected to the connecting hinge, and the spare tire rack is used to fix the spare tire; the spare tire is fixed relative to the door body, and when the door body is opened relative to the vehicle body, the spare tire and the door body open relative to the vehicle body together.
[0030] Specifically, the door body includes an inner panel 1 and an outer panel 3, and a reinforcing plate 2 is disposed between the inner panel 1 and the outer panel 3 to reinforce the door body and improve the strength of the door body. The reinforcing plate 2 is close to the area of the connecting portion 4, that is, the reinforcing plate 2 can also reinforce the connecting hinge while reinforcing the door body, thereby improving the strength of the connecting hinge. The connecting hinge is a structure for the door body to rotate relative to the vehicle body, and the connecting hinge is connected to the spare tire rack. By improving the strength of the connecting hinge, the strength of the door body when rotating relative to the vehicle body is improved, and the strength of the spare tire rack connected to the connecting hinge is also improved, thereby improving the support effect of the spare tire rack.
[0031] Furthermore, the reinforcing plate 2 extends from the position near the connecting hinge along the width direction of the vehicle, and the end of the reinforcing plate 2 away from the connecting hinge can be located in the middle of the width direction of the vehicle, so that the reinforcing plate 2 is arranged in a part of the door body, which can play a reinforcing role while reducing the weight of the entire back door 100, and strengthen the connecting hinge where the spare tire bracket is installed on the door body. Of course, the reinforcing plate 2 can also be arranged in the entire width direction of the vehicle, and can be selectively arranged according to actual conditions.
[0032] Therefore, in the tailgate 100 of the embodiment of the utility model, the reinforcing plate 2 is close to the connecting portion 4 and the connecting hinge area, which improves the strength of the tailgate 100 while also strengthening the connecting portion 4 and the connecting hinge, thereby improving the reliability of the spare tire being connected to the connecting hinge through the spare tire rack.
[0033] In some embodiments, the reinforcing plate 2 is provided with a first reinforcing rib 21 , and the inner plate 1 is provided with a second reinforcing rib 11 , and the first reinforcing rib 21 and the second reinforcing rib 11 are spaced apart and distributed along the width direction of the vehicle.
[0034] In practice, the first reinforcing rib 21 of the reinforcing plate 2 extends along the up-down direction of the vehicle, and the second reinforcing rib 11 of the inner panel 1 extends along the up-down direction of the vehicle. When the first reinforcing rib 21 of the reinforcing plate 2 and the second reinforcing rib 11 of the inner panel 1 are spaced apart in the width direction of the vehicle, the number of reinforcing ribs can be reduced while the overall strength of the tailgate 100 can be improved.
[0035] Specifically, refer to Figure 1 As shown, the first reinforcing rib 21 and the second reinforcing rib 11 can be constructed as convex ribs, and the first reinforcing rib 21 and the reinforcing plate 2 are integrally formed, and the second reinforcing rib 11 and the inner plate 1 are integrally formed. The first reinforcing rib 21 and the second reinforcing rib 11 can both be arranged in multiple areas, or the first reinforcing rib 21 is arranged in one area and the second reinforcing rib 11 is arranged in multiple areas along the width direction of the vehicle. It can be designed according to actual conditions and meet the strength requirements.
[0036] In some embodiments, the reinforcing plate 2 is provided with a plurality of first weight-reducing holes 22 , and the first reinforcing rib 21 is provided between two adjacent first weight-reducing holes 22 .
[0037] In practice, when the reinforcing plate 2 is provided with a plurality of first weight-reducing holes 22, and the plurality of first weight-reducing holes 22 are spaced apart in the vehicle width direction, a first reinforcing rib 21 may be provided in the region formed between adjacent first weight-reducing holes 22 to improve the strength between two adjacent first weight-reducing holes 22. The design of the first weight-reducing holes 22 can reduce the weight of the reinforcing plate 2, while enabling the reinforcing plate 2 to reinforce the connecting portion 4 of the vehicle tailgate 100 and other main body positions of the vehicle tailgate 100.
[0038] like Figure 2 In the embodiment of the utility model, two first weight-reducing holes 22 are provided, and the first reinforcing rib 21 is provided in the area between the two first weight-reducing holes 22, so as to appropriately reduce the weight while ensuring the reinforcing effect of the reinforcing plate 2.
[0039] In some embodiments, the inner panel 1 is provided with a plurality of second weight-reducing holes 12 , the second reinforcing ribs 11 are provided between adjacent second weight-reducing holes 12 , and the first reinforcing ribs 21 are opposite to the second weight-reducing holes 12 along the inner and outer directions of the rear door 100 .
[0040] Among them, the multiple second weight-reducing holes 12 of the inner panel 1 can reduce the weight of the inner panel 1. At the same time, the second reinforcing ribs 11 arranged between adjacent second weight-reducing holes 12 can increase the strength of the inner panel 1. When the reinforcing plate 2 is connected between the inner panel 1 and the outer panel 3, the first reinforcing ribs 21 of the reinforcing plate 2 are opposite to the second weight-reducing holes 12 of the inner panel 1 along the inside and outside directions of the rear door 100, so that the second reinforcing ribs 11 of the inner panel 1 and the first reinforcing ribs 21 of the reinforcing plate 2 can be staggered, thereby improving the overall rigidity and achieving the effect of weight reduction.
[0041] Specifically, refer to Figure 1 As shown, the inner panel 1 has three second weight reducing holes 12 and the reinforcing panel 2 has two first weight reducing holes 22. The second weight reducing holes 12 are evenly spaced on the inner panel 1 along the width direction of the vehicle. The second reinforcing ribs 11 can be opposite to a part of the first weight reducing holes 22 of the reinforcing panel 2, and of course can also be opposite to the area outside the first weight reducing holes 22. The first reinforcing ribs 21 of the reinforcing panel 2 are opposite to the second weight reducing holes 12 located in the middle. When the reinforcing panel 2 is connected to the inner panel 1 and the outer panel 3, the reinforcing panel 2 improves the strength of the middle area of the tailgate 100.
[0042] In some embodiments, there are at least two second reinforcing ribs 11 , and the two second reinforcing ribs 11 are symmetrical along the center of the second lightening hole 12 located between the two second reinforcing ribs 11 .
[0043] That is to say, the two second reinforcing ribs 11 are spaced apart along the width direction of the vehicle, and the two second reinforcing ribs 11 have the same shape, and the two second reinforcing ribs 11 are symmetrically distributed on both sides of the second weight reducing hole 12 in the middle, thereby making the strength of the two second reinforcing ribs 11 along the width direction of the vehicle and close to both sides of the vehicle more uniform, that is, the two second reinforcing ribs 11 are evenly stressed on both sides of the second weight reducing hole 12 in the middle, thereby preventing stress from being concentrated on one side of the second weight reducing hole 12 and causing deformation of the inner panel 1.
[0044] In some embodiments, each second reinforcing rib 11 is disposed obliquely relative to the vertical direction of the vehicle.
[0045] In practice, when each second reinforcing rib 11 is tilted relative to the vertical direction of the vehicle, the force on the tailgate 100 is more stable, and when the tailgate 100 is subjected to external force, the force is not limited to the vertical direction and the transmission along the width direction of the vehicle; for example, each second reinforcing rib 11 gradually approaches the side of the vehicle from the bottom to the top of the vehicle, and when encountering a rear bottom collision, the force can be transmitted to both sides in the width direction of the vehicle; in addition, the tilted second reinforcing rib 11 allows the second reinforcing rib 11 to be set longer when it is set between the two second weight-reducing holes 12, which can appropriately improve the strength of the inner panel 1.
[0046] In some embodiments, the edge of the reinforcing plate 2 is connected to the adapter plate 5 , the inner plate 1 is connected to the adapter plate 5 , and the middle of the reinforcing plate 2 is connected to the outer plate 3 .
[0047] That is to say, the edge of the reinforcing plate 2 can be connected to the inner panel 1 through the adapter plate 5, and the middle position of the reinforcing plate 2 is connected to the outer panel 3, so that the inner and outer sides of the reinforcing plate 2 are respectively connected to the inner panel 1 and the outer panel 3, and the position where the reinforcing plate 2 is connected to the inner panel 1 and the position where the reinforcing plate 2 is connected to the outer panel 3 are staggered along the inward and outward directions of the vehicle door body, which further improves the reliability of the connection between the reinforcing plate 2 and the outer panel 3.
[0048] Reference Figure 2 As shown, the reinforcing plate 2 is mainly concentrated at the lower part of the rear door 100 of the vehicle, one end of the reinforcing plate 2 along the width direction of the vehicle is connected to a position close to the connecting hinge, and the reinforcing plate 2 is connected to an adapter plate 5 along the upper part of the vehicle, and an adapter plate 5 is also provided at a position of the reinforcing plate 2 close to the connecting hinge, the adapter plate 5 is located on the inner side of the reinforcing plate 2, each adapter plate 5 is provided with an adapter flange 51, the reinforcing plate 2 is provided with a reinforcing flange 24, the adapter plate 5 and the reinforcing plate 2 are connected by the adapter flange 51 and the reinforcing flange 24, and the adapter plate 5 is a curved structure, so that a reinforced space is formed after the adapter plate 5 is connected to the reinforcing plate 2, and the reinforcing plate 2 and the inner panel 1 are connected by means of the adapter plate 5, which improves the connection strength between the reinforcing plate 2 and the inner panel 1, and can increase the connection area between the inner panel 1 and the reinforcing plate 2, thereby improving the reliability of the connection.
[0049] Furthermore, part of the area of the inner panel 1 is connected to the adapter plate 5, part of the area is connected to the support portion 23 of the reinforcing plate 2, and part of the area is connected to the reinforcing flange 24 of the reinforcing plate 2; in addition, part of the area of the inner panel 1 is partially connected to the outer panel 3, thereby improving the integrity of the connection between the outer panel 3, the reinforcing plate 2 and the inner panel 1.
[0050] In some embodiments, the reinforcing plate 2 is provided with a supporting portion 23 protruding toward the inner plate 1 , and the reinforcing plate 2 is also connected to the inner plate 1 via the supporting portion 23 .
[0051] In practice, the reinforcing plate 2 and the inner plate 1 are connected at the edge by the adapter plate 5, and are also connected to the inner plate 1 by the support portion 23, so that the edge position of the reinforcing plate 2 and the connection position of the inner plate 1 are increased, and the reliability of the connection between the reinforcing plate 2 and the inner plate 1 is improved. The middle position of the reinforcing plate 2 is connected to the outer plate 3, and the edge position is connected to the inner plate 1, that is, the reinforcing plate 2 is connected to the outer plate 3. More areas improve the integrity between the reinforcing plate 2 and the outer plate 3, and the support portion 23 of the reinforcing plate 2 can both connect to the inner plate 1 and support the inner plate 1.
[0052] In some embodiments, the reinforcing plate 2 and the inner plate 1 are provided with a first groove and a second groove on one side facing each other, respectively. After the reinforcing plate 2 is connected to the inner plate 1 , the first groove and the second groove form a reinforcing cavity.
[0053] The reinforcement cavity formed by the reinforcement plate 2 and the inner plate 1 can enhance the buffering performance of the tailgate 100 , thereby reducing the weight and improving the strength of the tailgate 100 .
[0054] In addition, an inner panel flange is provided around the inner panel 1 so that the inner panel 1 forms a second groove, and the reinforcing panel 2 is provided with a reinforcing flange 24. The setting of the reinforcing flange 24 forms a first groove on the reinforcing panel 2; that is, part of the area of the inner panel flange is connected to the adapter plate 5, and part of the area is connected to the reinforcing flange 24, and part of the inner panel flange remains connected to the outer panel 3, so that the inner panel 1, the outer panel 3 and the reinforcing panel 2 are connected as a whole and a reinforcing cavity is formed between the reinforcing panel 2 and the inner panel 1, thereby improving the strength of the tailgate 100.
[0055] The utility model embodiment also discloses a vehicle, including the above-mentioned tailgate 100, and the reinforcing plate 2 is close to the connecting portion 4 and the connecting hinge area, which improves the strength of the tailgate 100 while also strengthening the strength of the connecting portion 4 and the connecting hinge, thereby improving the reliability of the spare tire connected to the connecting hinge through the spare tire rack, thereby improving the safety of vehicle driving.
