[0002] At present, the upper door frame of the side panel structure corresponding to the rear door opening of some car models is an open structure, such as the gull-wing door car model. In this case, the door frame structure with an open top at the rear door opening will lead to insufficient rigidity of the side panel outer panel, and the car side panel structure only relies on the thin side panel outer panel below, resulting in extremely poor overall stability; moreover, during the production process of the vehicle, the door frame structure with an open top means that there is insufficient support, which will cause the front and rear sections of the car side panel structure to be more easily subjected to twisting force at the door frame structure with an open top when the whole is transported or loaded, and it is very easy to twist and deform; at the same time, the door frame structure with an open top makes the weight distribution of the front and rear sections of the car side panel structure uneven, and then, there is no suitable fixed point to arrange the gripper during transportation or loading, resulting in sliding or rotation of the components during transportation and loading, thereby affecting its structural stability and causing a decrease in manufacturing accuracy.

In the description of the present invention, unless otherwise specified, "plurality" means two or more.
[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0032] In the present invention, in order to better illustrate the structure of the side structure of the automobile and its connection relationship, the "upper end" referred to in the present invention is Figure 1 The upper side of the vehicle side structure shown in FIG. 1 (i.e., the upper side of the vehicle); the "lower end" referred to in the present utility model is Figure 1 The "front end" as used in this invention refers to the lower part of the side structure of the automobile shown in FIG. Figure 1 The left side of the side structure of the vehicle shown in the figure (i.e., the front side of the vehicle when it is moving forward normally), the "rear end" referred to in the present utility model is Figure 1 The right side of the vehicle side structure shown in (i.e. the rear side when the vehicle is moving forward normally).
[0033] like Figure 1 to Figure 2 As shown, an embodiment of the utility model provides a side structure of an automobile, comprising a front section 10 of a side outer panel and a rear section 20 of a side outer panel, wherein the front section 10 of the side outer panel comprises a first lower side beam 11 arranged below the rear door opening of the automobile, and the rear section 20 of the side outer panel comprises a second lower side beam 21 arranged below the rear door opening; the first lower side beam 11 and the second lower side beam 21 are overlapped; the first lower side beam 11 and the second lower side beam 21 are connected to a threshold cross beam 30 at a preset connection point 40. The first lower side beam 11 of the front section 10 of the side outer panel and the second lower side beam 21 of the rear section 20 of the side outer panel are overlapped below the rear door opening of the automobile, and the overlapped position is connected to the threshold cross beam 30 through a preset connection point, thereby completing the assembly of the side structure of the automobile and the threshold cross beam 30.
[0034] In the above-mentioned embodiment of the utility model, since the first lower side beam 11 of the front section 10 of the side outer panel arranged below the rear door opening of the automobile is overlapped with the second lower side beam 21 of the front section 10 of the side outer panel, the overlapping position of the first lower side beam 11 and the second lower side beam 21 will be connected to the door sill cross beam 30 below the rear door opening through a preset connection point 40. In this way, through the connection with the door sill cross beam 30, the connection stiffness between the front section 10 of the side outer panel and the rear section 20 of the side outer panel is enhanced, thereby enhancing the connection stiffness at the open position at the top end of the rear door opening of the automobile, thereby improving the overall stability of the side structure of the automobile. Furthermore, since the automobile side panel structure is composed of two structures, namely the front section 10 of the side panel outer panel and the rear section 20 of the side panel outer panel, during the production and transportation of the vehicle, the front section 10 of the side panel outer panel and the rear section 20 of the side panel outer panel of the automobile can be separately transported and loaded before being assembled, thereby avoiding the phenomenon of distortion and deformation of the open door frame structure at the top of the rear door opening of the automobile when subjected to torsional force, thereby improving the manufacturing accuracy; at the same time, it can also avoid the phenomenon of difficulty in arranging suitable grippers during transportation or loading due to uneven weight distribution of the front and rear sections of the automobile side panel structure, thereby facilitating transportation and loading.
[0035] In one embodiment, if Figure 2 As shown, the preset connection point 40 includes at least one of a welding connection point 41, an adhesive point 42, and a hot-melt fastening (FDS, Flow Drill Screw) connection point 43. It can be understood that the preset connection point is set at the connection position between the first lower side beam 11 of the side outer panel front section 10, the second lower side beam 21 of the side outer panel rear section 20, and the threshold cross beam 30. The preset connection point 40 can be set to at least one of the welding connection point 41, the adhesive point 42, and the hot-melt fastening connection point 43 according to the requirements of the specific position, as long as the strength, rigidity and durability of the whole vehicle and the side structure of the vehicle are guaranteed.
[0036] In one embodiment, if Figure 2As shown, the preset connection point 40 includes a welding connection point 41; wherein, the welding connection point includes a first welding point arranged at the upper end of the first lower side beam 11, a second welding point arranged at the upper end of the second lower side beam 21, and a third welding point arranged at the upper end of the threshold cross beam 30; the first welding point, the second welding point and the third welding point are spot-welded. Understandably, the first welding point, the second welding point and the third welding point are arranged relatively to each other, wherein the first welding point and the second welding point are arranged at the overlapping position of the first lower side beam 11 and the second lower side beam 12, and the first welding point, the second welding point and the third welding point are connected by welding. Specifically, local melting is generated between the metal sheets at the welding connection points (the first lower side beam 11, the second lower side beam 21 and the sill cross beam 30 are all made of metal materials), and the molten metal solidifies after cooling, thereby forming a firm connection between the above-mentioned welding connection points (that is, the first welding point, the second welding point and the third welding point), thereby enhancing the connection stiffness and strength between the upper end of the first lower side beam 11, the upper end of the second lower side beam 21 and the upper end of the sill cross beam 30, so as to ensure that the vehicle body is not easily deformed or damaged when subjected to external force.
[0037] In one embodiment, if Figure 2 As shown, the preset connection point 40 includes a bonding point 42; wherein the bonding point 42 refers to a bonding cavity formed between the overlap position of the first lower side beam 11 and the second lower side beam 21 and the threshold cross beam 30, and the first lower side beam 11, the second lower side beam 21 and the threshold cross beam 30 are bonded by the structural adhesive filled in the bonding cavity. It can be understood that at the overlap position of the first lower side beam 11 and the second lower side beam 21, the middle of the overlap position corresponds to the appearance surface of the vehicle. Therefore, in order to ensure the beautiful appearance of the vehicle, it is possible to set a hollow bonding cavity between the middle of the overlap position and the threshold cross beam 30, and fill the bonding cavity with structural adhesive, so that the middle section of the first lower side beam 11, the middle section of the second lower side beam 21 and the middle section of the threshold cross beam 30 are firmly bonded, and the appearance of the vehicle can be kept beautiful without opening a hole, thereby further enhancing the strength at the overlap position, and strengthening the sealing and reducing noise.
[0038] In one embodiment, if Figure 2As shown, the preset connection point 40 includes a hot melt fastening connection point 43; wherein, the hot melt fastening connection point 43 includes a first mounting hole set on the first lower side beam 11, a second mounting hole set on the second lower side beam 21, and a fixed connection point set on the threshold cross beam 30, and the threshold cross beam 30 is threadedly connected to the hot melt fastening screw passing through the first mounting hole and the second mounting hole at the fixed connection point. It can be understood that after the hot-melt fastening screw passes through the first mounting hole on the first lower side beam 11 and the second mounting hole on the second lower side beam 21, it is opposite to the fixed connection point on the sill cross beam 30. At this time, by rotating the hot-melt fastening screw, self-tapping can be performed on the fixed connection point on the sill cross beam 30, and the fixed connection point and the hot-melt fastening screw can be fixedly connected. Then, the lower section of the first lower side beam 11, the lower section of the second lower side beam 21 and the lower section of the sill cross beam 30 are firmly connected by the hot-melt fastening screw. The connection method of the hot-melt fastening point 43 can be suitable for the connection between different materials, which is convenient for rapid installation and disassembly on the production line, and can further improve the overall strength and rigidity of the vehicle body structure.
[0039] In some embodiments, three types of preset connection points 40, namely, welding connection points 41, bonding points 42, and hot melt fastening connection points 43, can be arranged vertically in sequence at the connection positions between the first lower side beam 11 of the front section 10 of the side outer panel, the second lower side beam 21 of the rear section 20 of the side outer panel, and the sill cross beam 30, so as to further enhance the rigidity and strength of the vehicle body. It is understandable that in some embodiments, only one or two of the three types of preset connection points 40, namely, welding connection points 41, bonding points 42, and hot melt fastening connection points 43, can be arranged. In the present utility model, one or more of each type of preset connection points 40 can be arranged, which is not limited here.
[0040] In one embodiment, if Figure 3 to Figure 4As shown, the side panel front section 10 also includes a first outer panel 12, a door ring 13 installed on the first outer panel 12, and a reinforcing plate 14 connected between the first outer panel 12 and the door ring 13; the first lower side beam 11 is connected to the first outer panel 12. It is understandable that the first outer panel 12 can be an integrally formed structural member with the first lower side beam 11. In this embodiment, from the outside of the vehicle to the inside of the vehicle, the side panel front section 10 is sequentially connected by the first outer panel 12, the reinforcing plate 14 and the door ring 13, thereby enhancing the rigidity of the side panel front section 10. Further, the first outer panel 12, the reinforcing plate 14 and the door ring 13 are spot-welded. It is understandable that the first outer panel 12 and the reinforcing plate 14, as well as the reinforcing plate 14 and the door ring 13 are all connected by resistance spot welding, with high connection strength and low cost. In some embodiments, the first outer plate 12 and the reinforcing plate 14 , as well as the reinforcing plate 14 and the door ring 13 , may be connected by threaded connection, riveted connection, clamping connection, etc., which are not limited here.
[0041] In one embodiment, if Figures 5 and 6 As shown, the side outer panel rear section 20 also includes a second outer panel 22 and a wheel cover assembly 23 connected to the second outer panel 22; the second lower side beam 21 is connected to the second outer panel 22. It is understandable that the second outer panel 22 can be an integrally formed structural member with the second lower side beam 21. In this embodiment, the side outer panel rear section 20 is composed of the second outer panel 22 and the wheel cover assembly 23, the second outer panel 22 is connected to the second lower side beam 21, and the side outer panel rear section 20 forms a door frame structure with an open top at the rear door opening. In this embodiment, the second outer panel 22 can be connected to the outside of the wheel cover assembly 23, thereby enhancing the rigidity and strength of the side outer panel rear section 20. Further, the second outer panel 22 and the wheel cover assembly 23 are spot-welded. It is understandable that the second outer panel 22 and the wheel cover assembly 23 are connected by resistance spot welding, and the connection strength is high and the cost is low. In some embodiments, the second outer panel 22 and the wheel cover assembly 23 may also be connected by threaded connection, riveted connection, snap connection, etc., which is not limited here.
[0042] In one embodiment of the utility model, when the side structure of the automobile needs to be assembled, firstly, the first outer panel 12 (the first outer panel 12 and the first lower side beam 11 are an integrally formed structural member), the reinforcing plate 14 and the door ring 13 are respectively mounted on the installation station, and the first outer panel 12, the reinforcing plate 14 and the door ring 13 are matched with each other by fixing and clamping with a clamp, and then the three are connected by resistance welding to form the side outer panel front section 10; thereafter, the second outer panel 22 (the second outer panel 22 and the second lower side beam 21 are an integrally formed structural member) and the wheel cover assembly 23 are respectively mounted on the installation station, and the second outer panel 22 and the wheel cover assembly 23 are matched with each other by fixing and clamping with a clamp. Then, the two are connected by resistance welding to form the rear section 20 of the side outer panel; then, the front section 10 of the side outer panel and the rear section 20 of the side outer panel are transported to the vehicle body assembly station, and the front section 10 of the side outer panel and the rear section 20 of the side outer panel are respectively assembled, and the first lower side beam 11 and the second lower side beam 21 are overlapped by fixing and clamping by a clamp, and the overlapping position of the first lower side beam 11 and the second lower side beam 21 is matched with the door sill crossbeam 30, and then the door sill crossbeam 30 and the overlapping position of the first lower side beam 11 and the second lower side beam 21 are connected at the welding connection point 41, the bonding point 42 and the hot-melt fastening connection point 43, and finally the assembly of the vehicle side structure is completed.

In the vehicle in the above-mentioned embodiment of the utility model, the automobile side panel structure comprises a side panel front section 10 and a side panel rear section 20, the side panel front section 10 comprises a first lower side beam 11 arranged below the rear door opening of the automobile, and the side panel rear section 20 comprises a second lower side beam 21 arranged below the rear door opening; the first lower side beam 11 and the second lower side beam 21 are overlapped; the first lower side beam 11 and the second lower side beam 21 are connected to the threshold cross beam 30 at a preset connection point 40.
[0044] In the vehicle of the above-mentioned embodiment of the utility model, since the first lower side beam 11 of the front section 10 of the side outer panel arranged below the rear door opening of the automobile is overlapped with the second lower side beam 21 of the front section 10 of the side outer panel, the overlapping position of the first lower side beam 11 and the second lower side beam 21 will be connected to the door sill cross beam 30 below the rear door opening through a preset connection point 40. In this way, through the connection with the door sill cross beam 30, the connection stiffness between the front section 10 of the side outer panel and the rear section 20 of the side outer panel is enhanced, thereby enhancing the connection stiffness at the open position at the top end of the rear door opening of the automobile, thereby improving the overall stability of the side structure of the automobile. Furthermore, since the automobile side panel structure is composed of two structures, namely the front section 10 of the side panel outer panel and the rear section 20 of the side panel outer panel, during the production and transportation of the vehicle, the front section 10 of the side panel outer panel and the rear section 20 of the side panel outer panel of the automobile can be separately transported and loaded before being assembled, thereby avoiding the phenomenon of distortion and deformation of the open door frame structure at the top of the rear door opening of the automobile when subjected to torsional force, thereby improving the manufacturing accuracy; at the same time, it can also avoid the phenomenon of difficulty in arranging suitable grippers during transportation or loading due to uneven weight distribution of the front and rear sections of the automobile side panel structure, thereby facilitating transportation and loading.
