[0040] At present, the commonly used side outer panel assembly structure has higher problems.

[0041] The existing traditional side outer panel assembly and even the largest sheet metal part in the steel body are side outer panels. And due to the increasingly stringent requirements for the safety performance of the vehicle body, in order to meet various safety index requirements, the parts of the side outer panel assembly tend to increase and thicken.

[0042] However, increasing the parts of the side outer plate assembly will cause the weight of the automobile body to increase significantly, especially for new energy vehicles, the endurance mileage is extremely sensitive to the weight of the automobile body, and it is urgent to reduce the weight of the automobile body.

[0043] To solve the above problems, the present application provides a side outer plate assembly structure 100, Figures 1 to 3 The present application provides a specific embodiment of the side outer plate assembly structure.

[0044] Please refer to Figures 1 to 3 , the side outer plate assembly structure 100 includes a side outer plate reinforcing plate assembly 1, an upper side beam outer plate 2, and a rear outer plate 3, the side outer plate reinforcing plate assembly 1 includes a door ring 11, the door ring 11 is welded as a whole by a plurality of parts, used for mounting on one side of the vehicle frame in the transverse direction, the upper side beam outer plate 2 is fixedly installed at the upper end of the side outer plate reinforcing plate assembly 1, the lower end of the upper side beam outer plate 2 is protrudingly arranged downward on one side in the transverse direction, the upper side beam outer plate 2 covers at least part of the upper end surface of the side outer plate reinforcing plate assembly 1, the rear outer plate 3 is installed on one side of the side outer plate reinforcing plate assembly 1 in the transverse direction, the upper end of the rear outer plate 3 abuts with the lower end of the upper side beam outer plate 2 on one side in the longitudinal direction, and covers at least part of the end surface of the side outer plate reinforcing plate assembly 1 in the transverse direction; wherein, the abutting position of the upper side beam outer plate 2 and the rear outer plate 3 is used to be covered by the automobile window glass.

[0045] In the technical scheme provided by the present application, the side outer plate reinforcing plate assembly 1, the upper side beam outer plate 2, and the rear outer plate 3 are provided, the traditional integral side outer plate is divided into parts, the side outer plate reinforcing plate assembly 1 includes the door ring 11, which can be used as a reinforcing structure 12 of the side outer plate assembly structure 100, the upper side beam outer plate 2 and the rear outer plate 3 are used as the appearance parts of the automobile body, and only cover at least part of the side outer plate reinforcing plate assembly 1, which reduces the A-pillar lower section, the rocker, and the B-pillar region compared with the traditional integral side outer plate; at the same time, the region of the side outer plate reinforcing plate assembly 1 which is not covered by the upper side beam outer plate 2 and the rear outer plate 3 is covered by the door assembly and the quarter window in the actual appearance of the automobile body, the abutting position of the upper side beam outer plate 2 and the rear outer plate 3 is covered by the window glass, and since the door ring 11 itself is a structural part, its yield strength meets the structural strength of the automobile body, and the weight of the door ring 11 is also less than that of the traditional side outer plate reinforcing plate assembly, so that the design can realize the substantial lightening of the side outer plate assembly structure 100 with little or even no influence on the side appearance and safety performance, and achieve a substantial weight reduction of 9 kg per vehicle.

[0046] Specifically, the side outer plate is arranged as a split structure of the upper side rail outer plate 2 and the rear outer plate 3, which greatly reduces the development cost of the side outer plate mold tooling and improves the material utilization. Since the traditional side outer plate assembly or even the largest sheet metal part in the steel body is the side outer plate, the size of the side outer plate part is too large, and therefore the development cost of the side outer plate mold tooling is usually high. Arranging the side outer plate as the split structure of the upper side rail outer plate 2 and the rear outer plate 3 can split the oversized side outer plate into small-sized parts, and the required mold tooling is also reduced, thereby achieving the purpose of reducing the development cost of the side outer plate mold tooling. Meanwhile, since the traditional side outer plate is a whole structure, two door holes need to be hollowed out in the middle of the material when processing, which results in low material utilization and serious waste. Arranging the side outer plate as the split structure of the upper side rail outer plate 2 and the rear outer plate can avoid the door hole area during manufacturing, and there is no need to hollow out the door hole, which greatly improves the material utilization and reduces the production cost. Such arrangement not only makes the manufacturing process of the side outer plate simpler, but also reduces the production cost of each vehicle by about 100 yuan, greatly reducing the development burden.

[0047] In order to further ensure the stability between the upper side rail outer plate 2 and the rear outer plate 3, prevent the upper side rail outer plate 2 and the rear outer plate 3 from not abutting each other or even being misaligned during vehicle driving, the upper side rail outer plate 2 and the rear outer plate 3 are connected as a whole, and the connection between the upper side rail outer plate 2 and the rear outer plate 3 is covered by the vehicle window glass. The upper side rail outer plate 2 and the rear outer plate 3 are arranged in a fixed connection, which further improves the stability. Since the upper side rail outer plate 2 and the rear outer plate 3 are covered by the vehicle window glass, the connection between the upper side rail outer plate 2 and the rear outer plate 3 has little or even no effect on the appearance of the vehicle body.

[0048] It should be noted that the connection mode of the upper side rail outer plate 2 and the rear outer plate 3 can be welding connection, bolt connection, or other fixed connection forms, and the present application does not limit this.

[0049] For example, in other embodiments of the present application, the upper side rail outer plate 2 and the rear outer plate 3 are connected by welding, the lower end surface of the upper side rail outer plate 2 along the longitudinal side is a welding surface, the upper end surface of the rear outer plate 3 is a matching surface corresponding to the welding surface, and the welding surface and the matching surface are mutually attached and connected by welding. Such arrangement can ensure the connection strength between the upper side rail outer plate 2 and the rear outer plate 3, and prevent the upper side rail outer plate 2 and the rear outer plate 3 from easily falling off.

[0050] Further, the side outer plate stiffening plate assembly 1 is composed of a door ring and other parts, the side outer plate stiffening plate assembly 1 further comprises a reinforcing structure 12, the reinforcing structure 12 is located on one side of the door ring 11 in the transverse direction and is fixedly connected with the door ring 11, the door ring 11, the upper side beam outer plate 2 and the rear wall outer plate 3 cover at least part of the reinforcing structure 12, and the upper side beam outer plate 2 further covers at least part of the upper end surface of the door ring 11. The door ring 11 is fixedly installed on one side of the reinforcing structure 12 in the transverse direction, and the door ring 11 is specifically installed between the A-pillar and the B-pillar of the automobile body. The door ring 11 and the reinforcing structure 12 are used to replace the traditional side outer plate stiffening plate assembly, which can further achieve the lightweight of the vehicle, and part of the door ring 11 and the reinforcing structure 12 are covered by the upper side beam outer plate 2 and the rear wall outer plate 3, so as not to affect the appearance of the automobile.

[0051] Since the upper side beam outer plate 2 only covers part of the upper end surface of the door ring 11, that is, the door ring exposed on the part of the upper side beam outer plate 2 also needs to be covered by other parts, the area of the side outer plate which is not covered by the upper side beam outer plate 2 and the rear wall outer plate 3 is a front door ring area, the door ring 11 is located in the front door ring area, and the front door ring area is used to be covered by the door assembly parts. The area of the door ring 11 which is not covered by the upper side beam outer plate 2 is covered by the door assembly parts, so that the door ring 11 can be completely covered and prevented from being exposed to the outside to affect the appearance of the automobile.

[0052] Specifically, referring to Figures 2 to 3 In the embodiment of the present application, a plurality of connecting holes 111 are arranged on one end of the door ring 11 in the transverse direction, a plurality of matching holes 121 are arranged on the reinforcing structure 12 corresponding to the plurality of connecting holes 111, the side outer plate assembly further comprises a plurality of connecting bolts 4 and fixing nuts 5 which cooperate with each other, one end of the connecting bolt 4 passes through the connecting hole 111 and the matching hole 121, and the fixing nut 5 is fixed to the part of the connecting bolt 4 which passes out of the connecting hole 111, so as to fix the door ring 11 on the reinforcing structure 12. The door ring 11 and the reinforcing structure 12 are connected by bolts, which has high locking force, and the plurality of connecting bolts 4 and the plurality of fixing nuts 5 cooperate with each other to fix the relative position of the door ring 11 and the reinforcing structure 12, so that the door ring 11 and the reinforcing structure 12 cannot relatively deviate or loosen, so that the door ring 11 can be stably installed on the reinforcing structure 12, the strength of the automobile body structure is guaranteed, and the safety performance meets the index requirements.

[0053] It should be noted that the connection form of the door ring 11 and the reinforcing structure 12 can also be a welded connection, a buckling connection, or other fixed connection form, and the present application does not make any limitation.

[0054] For example, in other embodiments of the present application, the connection form of the door ring 11 and the reinforcing structure 12 can also be fixedly connected to one side of the reinforcing structure 12 in the transverse direction by welding, and the door ring 11 and the reinforcing structure 12 are connected by welding at the mutual abutting position, and the welded connection can ensure the connection strength between the door ring 11 and the reinforcing structure 12, and the door ring 11 can be stably installed on one side of the reinforcing structure 12 in the transverse direction, without causing any impact on the structural strength of the automobile body.

[0055] Further, in the embodiments of the present application, the reinforcing structure 12 includes a C-pillar reinforcing plate 122, an upper D-pillar reinforcing plate 123, a lower D-pillar reinforcing plate 124, and a rear wheel cover reinforcing plate 125, the C-pillar reinforcing plate 122 is located on one side of the door ring 11 in the longitudinal direction and is used for being installed on the C-pillar, the upper D-pillar reinforcing plate 123 is located on the side of the C-pillar reinforcing plate 122 away from the door ring 11 and is fixedly connected with the C-pillar reinforcing plate 122, the lower D-pillar reinforcing plate is fixedly installed on the lower end of the upper D-pillar reinforcing plate 123, one end of the lower D-pillar reinforcing plate 124 in the longitudinal direction is fixedly connected with the C-pillar reinforcing plate 122, and the rear wheel cover reinforcing plate 125 is located on the lower end of the lower D-pillar reinforcing plate 124 and is fixedly connected with the lower D-pillar reinforcing plate 124. The C-pillar reinforcing plate 122, the upper D-pillar reinforcing plate 123, the lower D-pillar reinforcing plate 124, and the rear wheel cover reinforcing plate 125 are all fixedly connected, by setting the reinforcing structure 12 as a split structure, the size of a single part of the reinforcing structure can be reduced, the cost of mold tool development is reduced, and the material utilization rate during processing is improved, which is different from the integral structure, the reinforcing structure 12 does not need to hollow out a door hole in the middle of the sheet metal part during processing, but each part is combined and installed, thereby reducing the production cost.

[0056] In the embodiments of the present application, in order to further improve the structural strength of the reinforcing structure 12 and increase the overall structural strength of the automobile body, the reinforcing structure 12 further includes a plurality of reinforcing ribs 126, one end of each reinforcing rib 126 is fixedly connected with the lower D-pillar reinforcing plate 124, and the other end is fixedly connected with the rear wheel cover reinforcing plate 125. The plurality of reinforcing ribs 126 are arranged on the rear wheel cover reinforcing plate 125, which can further increase the structural strength of the rear wheel cover reinforcing plate, thereby further increasing the torsional stiffness of the rear part of the automobile body, so as to further improve the structural strength of the automobile body and improve the safety of the vehicle.

[0057] In order to further ensure the yield strength of the door ring, the material of the door ring 11 is set to be hot-stamping steel. The door ring 11 is manufactured by laser welding and hot stamping, that is, a hot-stamping integrated door ring, which is replaced by one part instead of multiple parts, optimizes the thickness distribution, only needs one set of stamping die, and is formed by one stamping operation without subsequent assembly, thereby reducing the process difficulty of manufacturing the side outer plate reinforcement plate assembly 1. Meanwhile, the hot-stamping integrated door ring can more effectively meet the requirements of the vehicle body structure strength, and the weight of the hot-stamping integrated door ring is lighter than that of the traditional side outer plate reinforcement plate assembly, so that the light weight of the automobile body is realized while the safety of the vehicle is improved.

[0058] In addition, the application provides an automobile, which comprises an automobile appearance cover and the side outer plate assembly structure 100, the automobile appearance cover is fixedly connected to one end of the side outer plate assembly structure 100 in the transverse direction and covers at least part of the side outer plate assembly structure 100.

[0059] Specifically, in the embodiments of the application, the upper side beam outer plate 2 and the rear wall outer plate 3 are at least partially exposed to the automobile appearance cover and form the appearance of the automobile body together with the automobile cover. Since the upper side beam outer plate 2 and the rear wall outer plate 3 can be used as the appearance parts of the automobile body, that is, the upper side beam outer plate 2 and the rear wall outer plate 3 are at least partially exposed to the automobile appearance cover, the appearance of the automobile is not affected.
