Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and more particularly to a door outer panel assembly, a door assembly, and a vehicle. Background Technology

[0002] In the existing technology, during the assembly of the car door assembly, the outer door panel and the outer panel waistline reinforcement plate are first pre-edge bound by a robot at the first workstation to form the outer door panel assembly. Then, the outer door panel assembly and the inner door panel assembly are edge-bound by a robot at the second workstation to complete the edge binding, forming the car door assembly.

[0003] It is evident that existing technologies require two robotic hemming workstations to work together, resulting in high equipment costs. Utility Model Content

[0004] This application provides a door outer panel assembly, a door assembly, and a vehicle, aiming to solve the problem in the prior art that two robotic hemming workstations are required to work together, resulting in high equipment costs.

[0005] To address the aforementioned issues, this application provides a door outer panel assembly, comprising a door outer panel, an outer panel waistline reinforcement plate, and rivets. The door outer panel is integrally formed, comprising an outer panel body and a bent portion extending along the front-rear direction of the vehicle. The bent portion includes an edging and a flange. The edging bends from the upper edge of the outer panel body to the lower edge of the outer panel body, covering the upper inner side of the outer panel body. The flange bends away from the edging, and a first through hole is provided on the flange. A second through hole is provided at the upper end of the outer panel waistline reinforcement plate, and the upper end of the outer panel waistline reinforcement plate is located inside the flange. The first through hole and the second through hole communicate to form a riveting hole. The rivets pass through the riveting hole to rivet the door outer panel to the outer panel waistline reinforcement plate.

[0006] The door outer panel assembly of this application embodiment is integrally formed. The door outer panel includes an outer panel body and a bent portion extending along the front-rear direction of the vehicle. The bent portion includes an edge and a flange. The edge bends from the upper edge to the lower edge of the outer panel body, covering the upper inner side of the outer panel body. The flange bends away from the edge and has a first through hole. The upper end of the outer panel waistline reinforcement plate has a second through hole, and the upper end of the outer panel waistline reinforcement plate is located inside the flange. The first through hole and the second through hole communicate to form a riveting hole. A rivet passes through the riveting hole to rivet the door outer panel and the outer panel waistline reinforcement plate together. Therefore, in the door outer panel assembly of this application embodiment, the door outer panel is directly formed with a bent portion, and the first through hole on the flange of the bent portion and the second through hole on the outer panel waistline reinforcement plate form a riveting hole. In this way, the rivets directly rivet the flange to the upper end of the outer panel waistline reinforcement plate through the rivet holes, achieving a fixed connection between the outer door panel and the outer panel waistline reinforcement plate. In the subsequent welding stage, only a single workstation robot is needed for edge rolling to combine the outer door panel assembly with the inner door panel assembly, eliminating the need for additional workstations or complex equipment. Compared to existing technologies, it eliminates the need for pre-edge wrapping of the outer door panel and outer panel waistline reinforcement plate in the first workstation, saving a robot edge rolling workstation and reducing equipment costs. Furthermore, the omission of one edge rolling process significantly improves production efficiency. Calculations show that the cycle time of a single workstation robot edge rolling is reduced by more than 20%, without requiring additional equipment or site modifications, resulting in an overall cost reduction of 40%-50%.

[0007] In addition, the outer door panel and the outer waistline reinforcement plate are riveted together, which ensures the connection strength and relative position of the outer door panel and the outer waistline reinforcement plate. The outer door panel can be formed into the bent part in one step by stamping die, replacing the step-by-step rolling process in the existing technology and eliminating the dependence on double workstations or press rolling.

[0008] Furthermore, in existing technologies, the outer door panel and the outer panel waistline reinforcement plate are individually hemmed, resulting in a longer dimensional chain and increased difficulty in precision control. The door outer panel assembly of this application omits one hemming process, shortening the dimensional chain and making precision control easier.

[0009] Optionally, a sealant is provided between the flange and the upper end of the outer panel waistline reinforcement plate.

[0010] An additional sealant is added between the flange and the upper end of the outer panel waistline reinforcement plate, which can not only seal the rivet holes, but also increase the connection strength between the outer door panel and the outer panel waistline reinforcement plate.

[0011] Optionally, a plurality of the first through holes are provided at intervals along the extending direction of the bent portion; The second through hole is provided in multiple ways to form multiple riveting holes; The rivets are provided in multiples, and each rivet passes through a corresponding riveting hole.

[0012] In this way, the outer door panel and the outer waistline reinforcement plate are riveted at multiple points to increase the connection strength.

[0013] Optionally, the flange is provided with a third through hole, and the upper end of the outer plate waistline reinforcing plate is provided with a fourth through hole. The third through hole and the fourth through hole are connected to form a water cutter mounting hole, which is used to install a water cutter.

[0014] The third through hole on the flange connects with the fourth through hole at the upper end of the outer panel waistline reinforcement plate to form a water cutter mounting hole, which is used to install the water cutter. That is, the structure for installing the water cutter is directly formed at the connection between the outer door panel and the outer panel waistline reinforcement plate, making the structure simpler.

[0015] Optionally, the water cutter mounting hole is a snap-fit ​​mounting hole, which is adapted to engage with the snap-fit ​​of the water cutter.

[0016] In this way, the water cutter is snapped together with the outer door panel assembly, and the connection process is simple.

[0017] Optionally, the inner surface of the edging and the inner surface of the flange form a receiving groove, which can accommodate the water cutter.

[0018] In this way, the water cutter is contained in the receiving groove formed by the inner surface of the edging and the inner surface of the flange, thus achieving concealment (the water cutter is not easily visible from the outside of the vehicle).

[0019] Optionally, the edging gradually slopes outward from top to bottom, and the flange gradually slopes inward from top to bottom.

[0020] In this way, the flange gradually slopes inward from top to bottom, which makes it easier to rivet the rivet into the rivet hole and to rivet the upper end of the flange and the outer panel waistline reinforcement plate.

[0021] Optionally, the angle between the flange and the vertical direction is less than or equal to 70 degrees.

[0022] The angle between the flange and the vertical direction is less than or equal to 70 degrees, making the molding of the outer door panel simpler.

[0023] On the other hand, this application provides a door assembly, including an inner door panel assembly, a water cutter, and an outer door panel assembly as described in the above embodiments. The inner door panel assembly is fixed to the inner side of the outer door panel assembly, and the water cutter is installed on the inner side of the flange and located between the upper end of the outer door panel and the upper end of the inner door panel assembly.

[0024] Optionally, the door inner panel assembly includes a door inner panel and an inner panel waistline reinforcement plate, wherein the upper end of the inner panel waistline reinforcement plate is fixed to the upper end of the door inner panel; The inner panel waistline reinforcement plate and the outer panel waistline reinforcement plate extend along the front-rear direction of the vehicle. The front side of the outer panel waistline reinforcement plate is fixedly connected to the front side of the inner door panel and the inner panel waistline reinforcement plate, and the rear side of the outer panel waistline reinforcement plate is fixedly connected to the rear side of the inner door panel and the inner panel waistline reinforcement plate. The inner door panel is edge-connected to the outer door panel.

[0025] The front side of the outer panel waistline reinforcement plate is fixedly connected to the front side of the inner door panel and the inner panel waistline reinforcement plate, and the rear side of the outer panel waistline reinforcement plate is fixedly connected to the rear side of the inner door panel and the inner panel waistline reinforcement plate. That is, the outer panel waistline reinforcement plate is not only fixedly connected to the inner panel waistline reinforcement plate, but also connected to the inner door panel, thereby improving the strength and rigidity of the entire door assembly.

[0026] In the door assembly of this embodiment, during the subsequent welding stage, only a single workstation robot is needed to roll the edges to combine the outer door panel assembly and the inner door panel assembly, eliminating the need for additional workstations or complex equipment. Compared to existing technologies, it eliminates the need for pre-edge binding of the outer door panel and the outer panel waistline reinforcement plate in the first workstation, saving a robot rolling workstation and reducing equipment costs. Furthermore, by omitting one rolling process, production efficiency is significantly improved.

[0027] In another aspect, this application provides a vehicle including the door outer panel assembly or the door assembly of the above embodiments.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0032] In this article, "front," "rear," "up," and "down" refer to the vehicle's orientation when it is normally placed on a horizontal plane. "Up" indicates the direction of the roof, "down" indicates the direction of the undercarriage, "front" points to the front of the vehicle, "rear" points to the rear of the vehicle, "inside" points to the inside of the vehicle, and "outside" points to the outside of the vehicle.

[0033] See Figures 1 to 3 This utility model provides a car door assembly 10, including an inner door panel assembly 2, a water-cooled section (not shown in the figure), and an outer door panel assembly 1. The inner door panel assembly 2 is fixed to the inner side of the outer door panel assembly 1. The outer door panel assembly 1 includes an outer door panel 11, an outer panel waistline reinforcing plate 12, and rivets 13. The outer door panel 11 is integrally formed and includes an outer panel body 111 and a bent portion 112 extending along the front-rear direction of the vehicle. The bent portion 112 includes an edging 1121 and a flange 1122. The edging 1121 bends from the upper edge of the outer panel body 111 to the lower edge of the outer panel body 111. The edging 1121 covers the inner side of the upper end of the outer panel body 111. The edge 1122 is bent away from the edge 1121. The flange 1122 is provided with a first through hole 11221. The upper end of the outer panel waistline reinforcing plate 12 is provided with a second through hole 121. The upper end of the outer panel waistline reinforcing plate 12 is located on the inner side of the flange 1122. The first through hole 11221 and the second through hole 121 are connected to form a riveting hole 14. The rivet 13 passes through the riveting hole 14 to rivet the outer door panel 11 to the outer panel waistline reinforcing plate 12.

[0034] The water cutter is installed on the inner side of the flange 1122 and is located between the upper end of the outer door panel 11 and the upper end of the inner door panel assembly 2.

[0035] The vehicle door outer panel assembly 1 and the vehicle door assembly 10 of this application embodiment are integrally formed. The vehicle door outer panel 11 includes an outer panel body 111 and a bent portion 112 extending in the front-rear direction of the vehicle. The bent portion 112 includes an edge 1121 and a flange 1122. The edge 1121 bends from the upper edge of the outer panel body 111 to the lower edge of the outer panel body 111. The edge 1121 covers the upper inner side of the outer panel body 111. The flange 1122... The flange 1122 bends away from the edge 1121, and a first through hole 11221 is provided on the flange 1122. A second through hole 121 is provided at the upper end of the outer panel waistline reinforcing plate 12. The upper end of the outer panel waistline reinforcing plate 12 is located on the inner side of the flange 1122. The first through hole 11221 and the second through hole 121 communicate to form a riveting hole 14. A rivet 13 passes through the riveting hole 14 to rivet the outer door panel 11 to the outer panel waistline reinforcing plate 12. It can be seen that in the door outer panel assembly 1 of this application embodiment, the door outer panel 11 is directly formed with a bent portion 112. The first through hole 11221 on the flange 1122 of the bent portion 112 and the second through hole 121 on the outer panel waistline reinforcing plate 12 form a riveting hole 14. In this way, rivet 13 directly rivets the flange 1122 to the upper end of the outer panel waistline reinforcement plate 12 through the rivet hole 14, realizing the fixed connection between the outer door panel 11 and the outer panel waistline reinforcement plate 12. In the subsequent welding stage, only a single workstation robot is needed to roll the edges to combine the outer door panel assembly 1 and the inner door panel assembly 2, without the need for additional workstations or complex equipment. Compared with the existing technology, it is not necessary to pre-wrap the outer door panel 11 and the outer panel waistline reinforcement plate 12 in the first workstation, saving a robot rolling workstation and reducing equipment costs. In addition, the omission of one rolling process greatly improves production efficiency.

[0036] Calculations show that the single-workstation robot hemming cycle time is reduced by more than 20%, without requiring additional equipment or site modifications, resulting in a 40%-50% reduction in overall cost. Furthermore, the door outer panel 11 and the outer panel waistline reinforcing plate 12 are riveted, ensuring the connection strength and relative position of the two components. The door outer panel 11 can be formed in one step using a stamping die, replacing the step-by-step hemming process in existing technologies and eliminating reliance on dual-workstation or press hemming.

[0037] Furthermore, in the prior art, the outer door panel 11 and the outer panel waistline reinforcement plate 12 are individually hemmed, resulting in a longer dimensional chain and increased difficulty in precision control. The outer door panel assembly 1 of this application embodiment omits one hemming process, shortens the dimensional chain, and makes precision control easier.

[0038] In one embodiment, the door inner panel assembly 2 includes a door inner panel 21 and an inner panel waistline reinforcement plate 22, the upper end of which is fixed to the upper end of the door inner panel 21. The upper end of the inner panel waistline reinforcement plate 22 can be welded to the upper end of the door inner panel 21.

[0039] The inner panel waistline reinforcement plate 22 and the outer panel waistline reinforcement plate 12 extend along the front-rear direction of the vehicle. The front side of the outer panel waistline reinforcement plate 12 is fixedly connected to the front side of the inner door panel 21 and the inner panel waistline reinforcement plate 22, and the rear side of the outer panel waistline reinforcement plate 12 is fixedly connected to the rear side of the inner door panel 21 and the inner panel waistline reinforcement plate 22. For example, the front side of the outer panel waistline reinforcement plate 12 is welded to the front side of the inner door panel 21 and the inner panel waistline reinforcement plate 22, and the rear side of the outer panel waistline reinforcement plate 12 is welded to the rear side of the inner door panel 21 and the inner panel waistline reinforcement plate 22.

[0040] The inner door panel 21 is connected to the outer door panel 11 by an edge binding. The outer door panel 11 and the inner door panel 21 cannot be welded; they are only connected by an edge binding for positioning.

[0041] The front side of the outer panel waistline reinforcement plate 12 is fixedly connected to the front side of the inner panel 21 and the inner panel waistline reinforcement plate 22 of the door, and the rear side of the outer panel waistline reinforcement plate 12 is fixedly connected to the rear side of the inner panel 21 and the inner panel waistline reinforcement plate 22 of the door. That is, the outer panel waistline reinforcement plate 12 is not only fixedly connected to the inner panel waistline reinforcement plate 22, but also connected to the inner panel 21 of the door, thereby improving the strength and rigidity of the entire door assembly 10.

[0042] In one embodiment, a sealant is provided between the flange 1122 and the upper end of the outer panel waistline reinforcing plate 12.

[0043] An additional sealant is added between the flange 1122 and the upper end of the outer panel waistline reinforcement plate 12, which can achieve sealing at the riveting hole 14 while increasing the connection strength between the door outer panel 11 and the outer panel waistline reinforcement plate 12. The sealant provides full adhesion between the flange 1122 and the upper end of the outer panel waistline reinforcement plate 12, and the shear strength can be increased by 50%.

[0044] In one embodiment, along the extending direction of the bent portion 112, a plurality of first through holes 11221 are provided at intervals; a plurality of second through holes 121 are correspondingly provided to form a plurality of riveting holes 14. A plurality of rivets 13 are provided, and each rivet 13 passes through a corresponding riveting hole 14.

[0045] In this way, the outer door panel 11 and the outer waistline reinforcement plate 12 are riveted at multiple points to increase the connection strength.

[0046] In one embodiment, the flange 1122 is provided with a third through hole 11222, and the upper end of the outer plate waistline reinforcing plate 12 is provided with a fourth through hole 122. The third through hole 11222 and the fourth through hole 122 communicate to form a water cutter mounting hole 15, which is used to install a water cutter.

[0047] The third through hole 11222 on the flange 1122 communicates with the fourth through hole 122 at the upper end of the outer panel waistline reinforcement plate 12 to form a water cutter mounting hole 15, which is used to install a water cutter. That is, the structure for installing a water cutter is formed directly at the connection between the outer door panel 11 and the outer panel waistline reinforcement plate 12, which makes the structure simpler.

[0048] In one embodiment, the water-cutting mounting hole 15 is a snap-fit ​​mounting hole, which is adapted to engage with the snap-fit ​​of the water-cutting device. In this way, the water-cutting device is snap-fitted to the outer door panel assembly 1, simplifying the connection process.

[0049] In one embodiment, multiple third through holes 11222 are spaced apart along the extending direction of the bend 112; multiple fourth through holes 122 are correspondingly provided to form multiple water-cutting mounting holes 15. See also Figure 1 Along the extending direction of the bent portion 112, the first through hole 11221 and the third through hole 11222 are alternately arranged.

[0050] In one embodiment, the inner surface of the edging 1121 and the inner surface of the flange 1122 form a receiving groove 16, which can accommodate the water cutter. In this way, the water cutter is accommodated in the receiving groove 16 formed by the inner surface of the edging 1121 and the inner surface of the flange 1122, thus achieving concealment (the water cutter is not easily observed from the outside of the vehicle).

[0051] In one embodiment, the edging 1121 gradually slopes outward from top to bottom, and the flange 1122 gradually slopes inward from top to bottom. In this way, the flange 1122 gradually slopes inward from top to bottom, which can better rivet the rivet 13 into the rivet hole 14, and the riveting of the flange 1122 to the upper end of the outer panel waistline reinforcing plate 12 is easier.

[0052] In one embodiment, the angle between the flange 1122 and the vertical direction is less than or equal to 70 degrees.

[0053] In one embodiment, the first through hole 11221 and the third through hole 11222 are punched out on the outer panel 11 of the door at the same time, eliminating the positioning error caused by the existing step-by-step punching process.

[0054] In one embodiment, the rivet 13 is a pull riveting rivet. The rivet 13 is inserted into the riveting hole 14, and the rivet gun applies a pulling force to cause the tail of the rivet 13 to expand and lock. The rivet 13 is made of stainless steel or aluminum alloy.

[0055] The angle between the flange 1122 and the vertical direction is less than or equal to 70 degrees, making the forming (stamping) of the outer door panel 11 simpler.

[0056] The door assembly 10 of this application embodiment is obtained by the following method: (1) Stamping preforming. The sheet metal is stamped and drawn into the outer curved surface of the car door outer panel 11 through multi-station stamping to form a bent part 112. A first through hole 11221 and a third through hole 11222 are formed on the flange 1122 of the bent part 112. The multi-station composite mold here has drawing, flanging and punching stations to realize the drawing, flanging and punching of the sheet metal.

[0057] (2) Applying adhesive. Apply adhesive to the joint between the outer panel waistline reinforcing plate 12 and the flange 1122 of the bending part 112 (the adhesive line is continuous without breaks). Here, an automatic adhesive applicator (quantitative adhesive dispensing) is used, which can evenly apply sealant to the joint between the outer panel waistline reinforcing plate 12 and the flange 1122 of the bending part 112.

[0058] (3) Welding Positioning and Hemming. The outer door panel assembly 1 and the inner door panel assembly 2 are positioned by a fixture, and the robot rollers press the hemmed areas of the outer door panel 11 and the inner door panel 21. In addition, a single-workstation robot hemming system is adopted, integrating a robot, roller tool head, pressure sensor and vision positioning module. The fixture can be a high-precision fixture to fix the relative positions of the outer door panel 11, the outer panel waistline reinforcement plate 12, the inner door panel 21 and the inner panel waistline reinforcement plate 22.

[0059] (4) Riveting. The outer door panel 11 and the outer panel waistline reinforcement plate 12 are further connected by rivets 13 after applying adhesive to ensure the adhesive gap. The rivets 13 are inserted into the rivet holes 14, and the rivet gun applies tension to complete the locking, so as to fix the outer door panel 11 and the outer panel waistline reinforcement plate 12.
