The core of this structure lies in its innovative three-hinge design, which allows the door to open and close in a smoother and more stable manner while providing higher structural strength and durability. However, judging from the current use of the three-hinge door leaf, there are still defects such as small door opening angle and easy breakage, which affect driving safety. It is necessary to solve the above technical problems. Summary of the invention
[0003] The purpose of the embodiments of the present application is to provide a three-hinge seat reverse-folding door leaf forging structure to solve the technical problem of small door opening angle existing in the prior art.
[0004] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is: to provide a three-hinge seat reverse folding door leaf forging structure, including:
[0005] The bottom plate is provided with a first mounting hole perpendicular to the bottom plate surface;
[0006] A connector connected to the edge of the bottom plate and arranged at an angle to the bottom plate;
[0007] A supporting plate portion, connected to a side of the connecting body away from the bottom plate and extending in a direction away from the bottom plate to form an arc-shaped structure;
[0008] A side lug is connected to the support plate and has a second mounting hole parallel to the support plate, wherein the side lug extends toward the arching direction of the support plate
[0009] An inner lug is connected to the support plate portion and is provided with a third mounting hole parallel to the second mounting hole. The extending direction of the inner lug is opposite to the arching direction of the support plate portion.
[0010] Optionally, the cross-section of the connector is trapezoidal.
[0011] Optionally, the cross-sectional area of the connector gradually decreases from a side close to the base plate to a side close to the support plate portion.
[0012] Optionally, the inner lug is provided with an adapter hole coaxial with the second mounting hole.
[0013] Optionally, a convex strip is provided on a side of the bottom plate facing away from the connector.
[0014] Optionally, the convex strip protrudes from the surface of the bottom plate by 1 mm.
[0015] Optionally, the number of convex strips is three and they are distributed in a triangular pattern.
[0016] The beneficial effect of the three-hinge seat reverse folding door leaf forging structure provided by the present application is that: compared with the prior art, the first mounting hole for hinge connection in the present application is set on the bottom plate, the second mounting hole is set on the side lug, and the third mounting hole is set on the inner lug. Since the side lug and the inner lug extend in opposite directions, the distance between the second mounting hole and the third mounting hole is effectively increased, so the door opening angle can be effectively increased, which is far better than the prior art. In addition, the side lug and the inner lug in the present application are both installed on the support plate part. Since the support plate part extends in an arc structure in a direction away from the bottom plate, the shear force on the door leaf during operation can be effectively offset, thereby improving the structural strength of the three-hinge seat reverse folding door leaf forging structure in the present application.

[0028] Please also read Figures 1 to 5 Now, a three-hinge seat reverse folding door leaf forging structure provided in the embodiment of the present application is described. The three-hinge seat reverse folding door leaf forging structure includes a bottom plate 100, a connector 200, a support plate portion 300, a side lug 400 and an inner lug 500. Among them:
[0029] The base plate 100 is provided with a first mounting hole 101 perpendicular to its own plate surface; the connecting body 200 is connected to the edge of the base plate 100 and is arranged at an angle to the base plate 100; the supporting plate portion 300 is connected to the side of the connecting body 200 away from the base plate 100 and extends in an arc-shaped structure in a direction away from the base plate 100; the side lug 400 is connected to the supporting plate portion 300 and has a second mounting hole 401 parallel to the supporting plate portion 300, and the side lug 400 extends in the arching direction of the supporting plate portion 300; the inner lug 500 is connected to the supporting plate portion 300 and is provided with a third mounting hole 501 parallel to the second mounting hole 401, and the extension direction of the inner lug 500 is opposite to the arching direction of the supporting plate portion 300.
[0030] According to the above structure provided in this embodiment, the first mounting hole 101 for hinge connection in this embodiment is arranged on the bottom plate 100, the second mounting hole 401 is arranged on the side lug 400, and the third mounting hole 501 is arranged on the inner lug 500. Since the side lug 400 and the inner lug 500 extend in opposite directions respectively, the distance between the second mounting hole 401 and the third mounting hole 501 is effectively increased, so the door opening angle can be effectively increased, and it is more convenient for passengers to enter and exit the vehicle. At the same time, this design also helps to improve the overall aerodynamic performance of the vehicle, thereby reducing wind resistance and fuel consumption. It is far superior to the prior art. In addition, in this application, the side lug 400 and the inner lug 500 are both installed on the support plate portion 300. Since the support plate portion 300 extends in an arc structure in a direction away from the bottom plate 100, it can effectively offset the shear force on the door leaf during operation, thereby improving the structural strength of the three-hinge seat reverse folding door leaf forging structure in this embodiment.
[0031] In another embodiment of the present application, please refer to Figures 1 to 5 The cross-section of the connector 200 is trapezoidal. According to the above structure provided in this embodiment, the connector 200 with a trapezoidal cross-section can effectively improve the mechanical structural strength of the three-hinge seat reverse folding door leaf forging structure provided in this embodiment.
[0032] In another embodiment of the present application, please refer to Figures 1 to 5 The cross-sectional area of the connecting body 200 gradually decreases from the side close to the bottom plate 100 to the side close to the supporting plate 300. According to the above structure provided in this embodiment, on the basis of meeting the mechanical structural strength, the connecting body 200 adopts the above structure to effectively reduce the self-weight of the three-hinge seat reverse folding door leaf forging structure in this embodiment and reduce the production cost.
[0033] In another embodiment of the present application, please refer to Figures 1 to 5, the inner lug 500 is provided with an adapting hole 502 coaxial with the second mounting hole 401. According to the above structure provided in this embodiment, after the fastener is inserted into the second mounting hole 401, it can also pass through the adapting hole 502 provided on the inner lug 500, thereby effectively improving the connection stability of the three-hinge seat reverse folding door leaf forging structure in this embodiment. It can be understood that the fastener provided in this embodiment is a bolt, screw or pin structure commonly used in the art.
[0034] In another embodiment of the present application, please refer to Figures 1 to 5 , a convex strip 600 is provided on the side of the bottom plate 100 away from the connecting body 200. According to the above structure provided in this embodiment, when the fastener passes through the first mounting hole 101 and the connection port of the target structure, the convex strip 600 can be embedded in the target structure, so that the three-hinge seat reverse folding door leaf forging structure provided in this embodiment can be more tightly connected to the target structure. Further, in another embodiment of the present application, please refer to Figures 1 to 5 The convex strip 600 protrudes 1 mm from the surface of the bottom plate 100, which has a better connection effect.
[0035] In another embodiment of the present application, please refer to Figures 1 to 5 According to the above structure provided in this embodiment, three convex strips 600 are provided and distributed in a triangular pattern, which can be used to bear shear forces from different directions respectively, further reducing the force on the fastener itself, so that the three-hinge seat reverse folding door leaf forging structure provided in this embodiment can be more tightly connected to the target structure.
[0036] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
