[0033] The tailgate 10 includes an inner tailgate panel 100, an outer tailgate panel 200, a through light mounting plate 300, and a reinforcing plate 400. The inner tailgate panel 100 is connected to the vehicle body. The outer tailgate panel 200 includes an upper outer tailgate panel 210 and a lower outer tailgate panel 220, which are respectively connected to the side of the inner tailgate panel 100 away from the vehicle body. The through light mounting plate 300 is connected to the upper outer tailgate panel 210 and the lower outer tailgate panel 220, forming a mounting cavity 600. The through light mounting plate 300 spans across the mounting cavity 400. The cavity 600 has a first end 611 and a second end 612; the reinforcing plate 400 is located at the first end 611 or the second end 612 and is located between the through light mounting plate 300 and the tailgate inner panel 100. The reinforcing plate 400 includes a reinforcing main plate 410 and a first welding part 413. The reinforcing main plate 410 is partially connected to the tailgate inner panel 100. One end of the first welding part 413 is connected to one side of the reinforcing main plate 410. The end of the first welding part 413 away from the reinforcing main plate 410 is provided with a first welding surface 4131 that is correspondingly connected to the through light mounting plate 300.

[0034] The tailgate inner panel 100 is connected to the vehicle body. A groove can be provided around the circumference of the tailgate inner panel 100 to accommodate various components. The groove is located along the circumference of the tailgate inner panel 100, which can be considered as a square ring. The empty space in the center of the ring is used to install the rear window glass. The inner and outer edges of the square ring are higher than the middle part, thus forming the groove. The size of the groove at the lower part of the tailgate inner panel 100 is larger than the size at the upper part to meet the height requirements of the vehicle tailgate 10.

[0035] The tailgate outer panel 200 is divided into an upper tailgate outer panel 210 and a lower tailgate outer panel 220. The upper tailgate outer panel 210 and the lower tailgate outer panel 220 are spaced apart and are both fixed to the side of the tailgate inner panel 100 away from the vehicle body.

[0036] A through-beam light mounting plate 300 is fixed between the upper part 210 and the lower part 220 of the outer tailgate panel. The through-beam light mounting plate 300 and the inner tailgate panel 100 are spaced apart, such that the through-beam light mounting plate 300, the outer tailgate panel 200, and the inner tailgate panel 100 cooperate to form a mounting cavity 600. The through-beam light mounting plate 300 also spans across the first end 611 and the second end 612 of the mounting cavity 600. Furthermore, both ends of the through-beam light mounting plate 300 are fixedly connected to both ends of the inner tailgate panel 100. Finally, the through-beam light mounting plate 300 is fixed to the tailgate 10 of the vehicle to facilitate the mounting of the through-beam light onto the mounting plate 300.

[0037] The reinforcing plate 400 is located at the first end 611 or the second end 612 of the mounting cavity 600. Specifically, there may be two reinforcing plates 400, which may be located at the first end 611 and the second end 612 of the mounting cavity 600, respectively. The reinforcing plate 400 is fixed to the tailgate panel. Further, the reinforcing plate 400 may include a reinforcing main plate 410 and a first welding part 413. Part of the reinforcing main plate 410 is fixedly connected to the bottom of the mounting cavity 600, which can be understood as the bottom of the groove of the tailgate inner panel 100. The first welding part 413 may be located on the side of one reinforcing main plate 410 close to the other reinforcing main plate 410 and corresponds to the position of the through-light mounting plate 300. One end of the first welding part 413 is connected to the reinforcing main plate 410, and the other end of the first welding part 413 extends towards the through-light mounting plate 300 and then towards the other welding plate to form a first welding surface 4131, so that the first welding part 413 and the reinforcing main plate 410 form a "Z" shaped structure. The first welding surface 4131 is fixedly connected to the side of the through light mounting plate 300 near the tailgate inner panel 100, and finally the through light mounting plate 300 is connected to the tailgate inner panel 100 through the reinforcing plate 400.

[0038] Through the above-described embodiments, the reinforcing plate 400 is disposed in the mounting cavity 600, and the main body of the reinforcing plate is connected to the tailgate inner panel 100. The reinforcing plate 400 is also provided with a first welding part 413, which is connected to the through light mounting plate 300, thereby strengthening the connection between the tailgate inner panel 100, the reinforcing plate 400 and the through light mounting plate 300, and thus improving the rigidity and overall stability of the car tailgate 10.

[0039] In some embodiments, the tailgate 10 includes a reinforcing edge 414. A portion of the reinforcing main panel 410 has the reinforcing edge 414 on the side near the first welded portion 413. One end of the first welded portion 413, away from the first welded surface 4131, is connected to the side of the reinforcing edge 414 away from the reinforcing main panel 410. The reinforcing edge 414 is located on the side of the tailgate inner panel 100 near the first welded portion 413. The reinforcing edge 414 can be considered as a portion of the reinforcing main panel 410 near the first welded portion 413 that bends and extends away from the tailgate inner panel 100. The side of the reinforcing edge 414 away from the reinforcing main panel 410 is connected to the first welded portion 413. The first welding part 413 is connected to the through light mounting plate 300, so the first welding part 413 will bear part of the weight of the through light mounting plate 300. A reinforcing edge 414 is provided between the first welding part 413 and the reinforcing main plate 410 to transfer the force on the first welding part 413 to the reinforcing edge 414, thereby improving the stability between the through light mounting plate 300 and the reinforcing main plate 410.

[0040] In some embodiments, the mounting cavity 600 includes a first mounting cavity 610 circumferentially disposed along the tailgate inner panel 100 and a second mounting cavity 620 connecting the two ends of the first mounting cavity 610. The reinforcing main plate 410 includes a strip reinforcing plate 411 and a triangular reinforcing plate 412. The two strip reinforcing plates 411 are symmetrically disposed on both sides of the first mounting cavity 610, and the two triangular reinforcing plates 412 are symmetrically disposed in the second mounting cavity 620 at positions corresponding to the strip reinforcing plates 411. One end of the triangular reinforcing plate 412 is connected to a strip reinforcing plate 411, wherein the triangular reinforcing plate 412 is configured as a near-triangular shape. The first mounting cavity 610 can be understood as a groove circumferentially disposed on the tailgate inner panel 100, and the second mounting cavity 620 can be understood as a groove in the lower part of the tailgate inner panel 100 connecting the two ends of the first mounting cavity 610. The reinforcing plate 400 is located in both the first mounting cavity 610 and part of the second mounting cavity 620. The reinforced mainboard 410 includes a strip-shaped reinforcing plate 411 and a triangular reinforcing plate 412. The strip-shaped reinforcing plate 411 is located within the first mounting cavity 610, and the triangular reinforcing plate 412 is located within the second mounting cavity 620. The triangular reinforcing plate 412 is connected to the side of the strip-shaped reinforcing plate 411 closest to another reinforcing plate 400. The triangular reinforcing plate 412 increases the contact area between the reinforcing plate 400 and the tailgate inner panel 100, thereby improving the strength of the tailgate inner panel 100. Furthermore, the triangular reinforcing plate 412 is a near-triangular shape, which has a smaller area, is more stable, and has higher strength. The triangular reinforcing plate 412, located within the second mounting cavity 620, also reduces the risk of breakage between the upper and lower parts of the tailgate inner panel 100 due to excessive weight in the lower part. The upper part of the tailgate inner panel 100 refers to the portion of the tailgate inner panel 100 above the second mounting cavity 620.

[0041] Because a thicker reinforcing plate 400 would result in poor welding quality between it and the tailgate inner panel 100, the thickness of the reinforcing plate 400 was reduced to 12mm-15mm. While reducing the thickness improves welding quality, it also lowers the plate's own strength. Therefore, several structures were designed to enhance the strength of the reinforcing plate 400, as detailed below:

[0042] In some embodiments, the triangular reinforcing plate 412 includes a second welding portion 415 disposed inside the triangular reinforcing plate 412. The second welding portion 415 has a second welding surface 4151 spaced between the tailgate inner panel 100 and the triangular reinforcing plate 412. The second welding portion 415 also includes a surrounding reinforcing rib 4152 connecting the second welding surface 4151 and the triangular reinforcing plate 412. The tailgate inner panel 100 has a third welding portion 110 protruding towards the triangular reinforcing plate 412 and welded to the second welding portion 415. Figure 5 As shown, Figure 5 It can be understood as Figure 3A structural schematic diagram taken from the perspective of the tailgate inner panel 100 to the tailgate outer panel 200 shows the location of the third welded portion 110. The reinforcing plate 400 and the tailgate inner panel 100 are slightly spaced apart to form a cavity between them for energy absorption. To ensure the connection between the reinforcing plate 400 and the tailgate inner panel 100, a second welded portion 415 is provided on the triangular reinforcing plate 412. The second welded portion 415 includes a second welded surface 4151 and a surrounding reinforcing rib 4152. The second welded surface 4151 is spaced apart from the triangular reinforcing plate 412 and is located between the triangular reinforcing plate 412 and the tailgate inner panel 100. One side of the surrounding reinforcing rib 4152 is connected to the periphery of the second welded surface 4151, and the other side of the surrounding reinforcing rib 4152 is connected to the triangular reinforcing plate 412, thereby enhancing the strength of the second welded portion 415. Furthermore, a third welding part 110 is provided at the position corresponding to the second welding part 415 on the tailgate inner panel 100. The structure of the third welding part 110 is similar to that of the second welding part 415. The third welding part 110 protrudes towards the reinforcing plate 400 relative to the tailgate inner panel 100, and the third welding part 110 and the second welding part 415 are fixedly connected. The arrangement of the second welding part 415 and the third welding part 110 can not only strengthen the connection between the tailgate inner panel 100 and the reinforcing plate 400, but also improve the stability of the connection between the second welding part 415 and the third welding part 110. Multiple third welding parts 110 can be provided, and the multiple third welding parts 110 are arranged at intervals.

[0043] In some embodiments, the reinforcing plate 400 includes a first welding edge 416 and a second welding edge 417. The first welding edge 416 and the second welding edge 417 are respectively located on both sides of the reinforcing plate 400 and extend in a direction away from the tailgate inner panel 100. The first welding edge 416 is connected to the side of the strip reinforcing plate 411 away from the triangular reinforcing plate 412 and is fixedly connected to the tailgate inner panel 100. The second welding edge 417 connects both the side of the strip reinforcing plate 411 away from the first welding edge 416 and the side of the triangular reinforcing plate 412 and is fixedly connected to the tailgate inner panel 100. The first welding edge 416 and the second welding edge 417 are located on both sides of the reinforcing plate 400 and extend in a direction away from the tailgate inner panel 100. The first welding edge 416 is connected to the side of the strip reinforcing plate 411 away from the triangular reinforcing plate 412. The first welding edge 416 can be understood as the strip reinforcing plate 411 extending away from the triangular reinforcing plate 412 in a direction away from the tailgate inner panel 100, and having a third welding surface for welding to the tailgate inner panel 100. Multiple third welding surfaces are located at one end of the first welding edge 416 away from the strip reinforcing plate 411. A portion of one side of the second welding edge 417 is connected to the side of the strip reinforcing plate 411 away from the first welding edge 416, and another portion of the side of the second welding edge 417 is connected to the triangular reinforcing plate 412, thus connecting the triangular reinforcing plate 412 and the strip reinforcing plate 411 through the second welding edge 417. A fourth welding surface is located on the side of the second welding edge 417 away from the reinforcing main plate 410, with multiple fourth welding surfaces spaced apart on the side of the second welding edge 417 away from the reinforcing main plate 410, and the fourth welding surfaces are welded and fixed to the tailgate inner panel 100. The fourth welding surface protrudes relative to the second welding edge 417, forming a serrated shape, thereby improving the connection between the reinforcing plate 400 and the tailgate inner panel 100 while reducing the weight of the reinforcing plate 400. Both the first welding edge 416 and the second welding edge 417 extend towards the tailgate outer panel 200, forming a cavity with the first welding edge 416, the second welding edge 417, and the reinforcing main plate 410 to absorb energy, thus increasing the strength of the reinforcing plate 400. Furthermore, in addition to the first welding edge 416, the second welding edge 417, and the second welding portion 415, the remaining periphery of the reinforcing plate 400 is provided with spaced welding points to ensure a more secure connection between the reinforcing plate 400 and the tailgate inner panel 100.

[0044] In some embodiments, the tailgate inner panel 100 is provided with a gas spring mounting surface 120, and the tailgate inner panel 100 has a mounting notch at a position corresponding to the gas spring mounting surface 120. A first welding edge 416 has a gas spring welding portion 4161 at a position corresponding to the gas spring mounting surface 120. The tailgate 10 also includes a connecting plate 418, which connects the gas spring mounting surface 120 and the gas spring welding portion 4161. The connecting plate 418 also covers the mounting notch and is fixedly connected to the tailgate inner panel 100 around the mounting notch. The tailgate inner panel 100 is provided with a gas spring mounting surface 120, and the gas spring mounting surface 120 has mounting holes for mounting a gas spring. The gas spring is supported between the vehicle body and the tailgate 10, thereby facilitating the opening and closing of the tailgate 10. The gas spring mounting surface 120 corresponds to the first welding edge 416, and the first welding edge 416 is provided with a gas spring welding portion 4161 corresponding to the gas spring mounting surface 120. The gas spring welding portion 4161 can protrude relative to the first welding edge 416 towards the tailgate inner panel 100 to improve the strength of the gas spring welding portion 4161. The gas spring welding portion 4161 and the gas spring mounting surface 120 are fixedly connected, so that the force received by the gas spring mounting surface 120 can be connected to the reinforcing plate through the gas spring welding portion 4161, thereby improving the strength of the gas spring mounting surface 120. In addition, a connecting plate 418 is fixedly connected between the gas spring mounting surface 120 and the gas spring welding portion 4161, which can further improve the strength of the gas spring mounting surface 120 and reduce the risk of breakage of the gas spring mounting surface 120. The tailgate inner panel 100 also includes a mounting notch adjacent to the gas spring mounting surface 120. A connecting plate 418 is partially fixedly connected between the gas spring mounting surface 120 and the gas spring welded portion 4161. One end of the connecting plate 418 away from the gas spring mounting surface 120 extends toward the mounting notch, and the periphery of the extended portion of the connecting plate 418 is fixedly connected to the tailgate inner panel 100, thereby transmitting the force received by the connecting plate 418 to other parts of the tailgate inner panel 100. Furthermore, the extended portion of the connecting plate 418 extends away from the tailgate outer panel 200 relative to the portion connected to the gas spring mounting surface 120, forming an energy-absorbing cavity, thereby increasing the strength of the connecting plate 418.

[0045] In some embodiments, the strip reinforcing plate 411 has an adhesive surface 4111 in a direction perpendicular to the connecting line between the two ends of the first mounting cavity 610. The adhesive surface 4111 protrudes towards the tailgate inner panel 100, and is fixedly connected to the tailgate inner panel 100 by structural adhesive. The provision of the adhesive surface 4111 in a direction perpendicular to the connecting line between the two ends of the first mounting cavity 610 can be understood as the presence of the adhesive surface 4111 at a position corresponding to one end of the strip reinforcing plate 411 and the first mounting cavity 610. The adhesive surface 4111 may be elongated, and is connected to the tailgate inner panel 100 by structural adhesive. The adhesive surface 4111 may also protrude towards the tailgate inner panel 100 relative to the strip reinforcing plate 411, and may be provided with reinforcing ribs surrounding the periphery of the adhesive surface 4111. Because there is a gap between the adhesive surface 4111 and the tailgate inner panel 100, when the reinforcing plate 400 is under stress, the reinforcing plate 400 bends to resist the force, thereby bringing the adhesive surface 4111 closer to the tailgate inner panel 100. By connecting the reinforcing plate 400 and the tailgate inner panel 100 with structural adhesive, the force on the reinforcing plate 400 can be transmitted to the tailgate inner panel 100 through the adhesive surface 4111, and the abnormal noise caused by the impact between the reinforcing plate 400 and the tailgate inner panel 100 when under stress can also be avoided.

[0046] In some embodiments, the strip reinforcing plate 411 and the triangular reinforcing plate 412 are respectively provided with weight-reducing holes 419 and arc-shaped reinforcing ribs 420. A plurality of weight-reducing holes 419 located on the strip reinforcing plate 411 are spaced apart in the direction in which the adhesive surface 4111 is positioned. A plurality of weight-reducing holes 419 located on the triangular reinforcing plate 412 are spaced apart, and arc-shaped reinforcing ribs 420 are provided between the plurality of weight-reducing holes 419. The strip reinforcing plate 411 is provided with a plurality of weight-reducing holes 419, which are spaced apart from the adhesive surface 4111 in the direction in which the adhesive surface 4111 is positioned, to reduce the weight of the reinforcing plate 400. The triangular reinforcing plate 412 is also provided with spaced-apart weight-reducing holes 419. In addition, the strip reinforcing plate 411 and the triangular reinforcing plate 412 are also provided with arc-shaped reinforcing ribs 420 located between the weight-reducing holes 419. The arc-shaped reinforcing ribs 420 can be arranged at intervals with the weight-reducing holes 419 or can be arranged on the side of the weight-reducing holes 419, thereby reducing the weight of the reinforcing plate 400 while improving the strength of the reinforcing plate 400.

[0047] See Figure 6 , Figure 6 yes Figure 2 The diagram shows the structure of the connecting beam.

[0048] In some embodiments, the second mounting cavity 620 is provided with a connecting beam 500, which includes a through-lamp mounting surface 510 and a weld contact angle 520. The through-lamp mounting surface 510 is spaced apart from the tailgate inner panel 100, and the weld contact angle 520 is supported between the through-lamp mounting surface 510 and the tailgate inner panel 100. The side of the through-lamp mounting surface 510 away from the weld contact angle 520 is fixedly connected to the through-lamp mounting plate 300. The second mounting cavity 620 is provided with a connecting beam 500 at a position corresponding to the through-lamp mounting plate 300. The connecting beam 500 includes a through-lamp mounting surface 510 and a weld contact angle 520. The through-lamp mounting surface 510 is spaced apart from the tailgate inner panel 100, and the through-lamp mounting surface 510 and the side of the through-lamp mounting plate 300 near the tailgate inner panel 100 are fixedly connected by a plurality of spaced weld points. Multiple weld contact angles 520 are spaced apart on both sides of the through-light mounting surface 510. These contact angles support the tailgate inner panel 100 and the through-light mounting surface 510, thereby connecting the through-light mounting plate 300 to the tailgate inner panel 100 via the connecting beam 500, thus improving the strength of the through-light mounting plate 300. One end of the weld contact angle 520 on one side of the through-light mounting surface 510 is connected to the through-light mounting surface 510, and the other end extends towards the tailgate inner panel 100 and then away from the other side of the weld contact angle 520. This ensures that the end of the weld contact angle 520 away from the through-light mounting surface 510 forms a plane for welding with the tailgate inner panel 100, thereby improving the stability of the connecting beam 500. Multiple connecting beams 500 can be used; these beams are smaller in size but can be spaced apart, thus reducing the weight of the tailgate 10.

[0049] In some embodiments, the tailgate inner panel 100 is further provided with a main weight-reducing opening, which is located at a position corresponding to the upper part 210 of the tailgate outer panel. The main weight-reducing opening is provided with two symmetrically arranged oblique main support beams, which support the upper and lower ends of the main weight-reducing opening, dividing the main weight-reducing opening into three spaced-apart sub-weight-reducing openings. The sub-weight-reducing openings may also be provided with obliquely arranged sub-support beams, thereby reducing the weight of the lower part of the tailgate inner panel 100, reducing the load on the gas spring mounting surface 120, and improving the strength of the main weight-reducing opening. In addition, the vehicle tailgate 10 may also be provided with a support plate supporting the tailgate inner panel 100 and the tailgate outer panel 200. The support plate has planes near the ends of the tailgate inner panel 100 and the tailgate outer panel 200 that are respectively connected to the tailgate inner panel 100 and the tailgate outer panel 200, thereby strengthening the connection between the tailgate inner panel 100 and the tailgate outer panel 200, and thus improving the overall stability and strength of the vehicle tailgate 10.

[0050] In summary, the reinforcing plate 400 is disposed within the mounting cavity 600, and the main body of the reinforcing plate is connected to the tailgate inner panel 100. The reinforcing plate 400 is also provided with a first welding part 413, which is connected to the through light mounting plate 300, thereby strengthening the connection between the tailgate inner panel 100, the reinforcing plate 400 and the through light mounting plate 300, and thus improving the rigidity and overall stability of the car tailgate 10.
