[0048] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be more comprehensive and complete and fully convey the concept of the example embodiments to those skilled in the art.

[0050] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0051] It should also be noted that the first direction S1 mentioned in this embodiment can be understood as the axial direction of the vehicle length; the second direction S2 mentioned in this embodiment can be understood as the axial direction of the vehicle height; the third direction S3 mentioned in this embodiment can be understood as the axial direction of the vehicle width.

[0052] like Figures 1 to 3 As shown, this embodiment provides a side enclosure outer panel structure, including a side enclosure front portion 11, a side enclosure middle portion 12, and at least two side enclosure rear portions 13 / 13' with different design lengths in the first direction S1, which are divided and connected in sequence. The side enclosure middle portion 12 is configured to be able to selectively connect to the side enclosure rear portion 13 / 13'. In this way, the side enclosure rear portion 13 / 13' of the required design length can be selected according to the wheelbase requirements to be connected to the common side enclosure middle portion 12 and the side enclosure front portion 11, forming the side enclosure outer panel structure 1 of the required vehicle model, realizing the flexible conversion between the long-axis vehicle model and the short-axis vehicle model, improving the material utilization rate and the universality rate, and reducing the mold investment cost.

[0053] For example, Figures 1 to 3 As shown, the side panel structure 1 of this embodiment is configured with a side panel front portion 11, a side panel middle portion 12 and two side panel rear portions 13 / 13' with different design lengths in the first direction S1, wherein the side panel front portion 11 and the side panel middle portion 12 are fixedly connected by welding. When the required vehicle model is a short-axle vehicle model, as shown in FIG. Figure 1 and Figure 2 As shown, the side rear portion 13 with a shorter design length is fixedly connected to the side of the side middle portion 12 away from the side front portion 11 by welding, that is, the side outer panel structure 1 of the short-axle vehicle model is formed; when the required vehicle model is a long-axle vehicle model, as shown in FIG. Figure 3As shown, the side panel rear portion 13' with a longer design length can be fixedly connected to the side of the side panel middle portion 12 away from the side panel front portion 11 by welding, that is, the side panel outer panel structure of the long-axis vehicle model is formed; in this way, the side panel front portion 11 and the side panel middle portion 12 of the short-axis vehicle model and the long-axis vehicle model can be used interchangeably, which effectively improves the material utilization rate and the commonality rate.

[0054] Furthermore, if Figure 1 , Figure 2 and Figure 4 As shown, the side enclosure front portion 11 includes a side enclosure front lower module 112 divided and connected along the second direction S2 and at least two side enclosure front upper modules 111 with different design heights in the second direction S2, and the side enclosure front lower module 112 is configured to be able to selectively connect to the side enclosure front upper module 111; the side enclosure middle portion 12 includes a side enclosure middle lower module 122 divided and connected along the second direction S2 and at least two side enclosure middle upper modules 121 with different design heights in the second direction S2, and the side enclosure middle lower module 122 is configured to be able to selectively connect to the side enclosure middle upper module 121; the side enclosure rear portion 13 includes a side enclosure rear lower module 132 divided and connected along the second direction S2 and at least two side enclosure rear upper modules 131 with different design heights in the second direction S2 The side enclosure rear lower module 132 is configured to be able to selectively connect to the side enclosure rear upper module 131; wherein, the side enclosure front upper module 111, the side enclosure middle upper module 121 and the side enclosure rear upper module 131 are sequentially connected to form the side enclosure upper part, and the side enclosure front lower module 112, the side enclosure middle lower module 122 and the side enclosure rear lower module 132 are sequentially connected to form the side enclosure lower part, and the design heights of the side enclosure front upper module 111, the side enclosure middle upper module 121 and the side enclosure rear upper module 131 used to form the side enclosure upper part are adapted to each other. In this way, after selecting the wheelbase, the side enclosure upper part of the required design height can also be selected according to the top height requirement to be connected to the side enclosure lower part to form the side enclosure outer panel structure 1 of the required vehicle model, thereby further realizing the flexible conversion between high-top vehicles and low-top vehicles.

[0055] For example, Figure 1 , Figure 2 and Figure 4As shown, taking the side panel outer plate structure 1 of a short-axle vehicle as an example, the side panel front portion 11 of this embodiment is configured with a side panel front lower module 112 and two side panel front upper modules 111 / 111' with different design heights in the second direction S2, the side panel middle portion 12 is configured with a side panel middle lower module 122 and two side panel middle upper modules 121 / 121' with different design heights in the second direction S2, and the side panel rear portion 13 is configured with a side panel rear lower module 132 and two side panel rear upper modules 131 / 131' with different design heights in the second direction S2, wherein the side panel front lower module 112 is fixedly connected to the side panel middle lower module 122 by welding, and the side panel middle lower module 122 is fixedly connected to the side panel rear lower module 132 by welding to form the side panel lower portion; when the required vehicle model is a short-axle low-top vehicle model, as shown in FIG. Figure 1 and Figure 2 As shown, the side panel front upper module 111 with a lower design height, the side panel middle upper module 121 with a lower design height, and the side panel rear upper module 131 with a lower design height are respectively fixedly connected to the upper sides of the side panel front lower module 112, the side panel middle lower module 122, and the side panel rear lower module 132 by welding, so as to form the side panel outer panel structure 1 of the low-top vehicle model; when the required vehicle model is a short-axle high-top vehicle model, as shown in FIG. Figure 4 As shown, the side panel front upper module 111' with a higher design height, the side panel middle upper module 121' with a higher design height, and the side panel rear upper module 131' with a higher design height are fixedly connected to the upper sides of the side panel front lower module 112, the side panel middle lower module 122, and the side panel rear lower module 132 by welding, respectively, to form the side panel outer panel structure of the high-top vehicle model; in this way, the side panel lower modules of the short-axle high-top vehicle model and the short-axle low-top vehicle model can be interchangeable, which effectively improves the material utilization rate and the commonality rate.

[0056] Similarly, when the wheelbase requirement of the above-mentioned side panel structure is long, the modules of the side panel lower parts of the long-axis high-top vehicle and the long-axis low-top vehicle can also be used interchangeably. Therefore, it can be understood that the side panel structure with the same wheelbase but different top height can use the side panel lower part including the side panel front lower module 112, the side panel middle lower module 122 and the side panel rear lower module 132; the side panel structure with the same top height but different wheelbase can use the side panel front part 11 and the side panel middle part 12 including the side panel front upper module 111, the side panel front lower module 112, the side panel middle upper module 121 and the side panel middle lower module 122; and the side panel structure with different top heights and wheelbases, such as the long-axis high-top vehicle and the short-axis low-top vehicle, can also use the side panel front lower module 112 and the side panel middle lower module 122, which greatly ensures the material utilization rate and the commonality rate.

[0057] In some embodiments, Figure 1 , Figure 5 and Figure 6 As shown, the side enclosure middle portion 12 and / or the side enclosure rear portion 13 has a groove 14 that is concave inwardly arranged along the third direction S3, and the groove bottom of the groove 14 is configured to be able to be set in one of the integral structure 141 and the open hole structure 142; wherein, as Figure 5 As shown, when the groove bottom of the groove 14 is an integral structure 141, the side panel middle portion 12 and / or the side panel rear portion 13 of the side panel outer plate structure 1 are designed as a blind window structure; Figure 6 As shown, when the groove bottom of the groove 14 is an open hole structure 142, the side wall middle part 12 and / or the side wall rear part 13 of the side wall outer panel structure 1 is a clear window structure design, and the passenger window requirements can be met by setting fixed or movable glass 15 at the open hole structure 142. In this way, after selecting a vehicle model with a wheelbase and a top height, the side wall middle part 12 and / or the side wall rear part 13 with a required groove bottom structure can also be selected according to the use requirements to form the side wall outer panel structure 1 of the required vehicle model, further realizing the flexible conversion between passenger vehicles and cargo vehicles.

[0058] In combination with the aforementioned embodiments, the side outer panel structure 1 provided in the embodiments of the present application can be modularly universal for high-top vehicles, low-top vehicles, long-axle vehicles, short-axle vehicles, passenger vehicles and cargo vehicles, so that the material utilization rate and the universality rate are significantly improved, the mold development cost is effectively reduced, and the flexible production of the production line is realized.

[0059] In addition, if Figures 7 to 10 As shown, in an embodiment of the present application, a side enclosure assembly 10 is further provided, including a side enclosure inner panel structure 2 and the side enclosure outer panel structure 1 in the above embodiment, the side enclosure inner panel structure 2 and the side enclosure outer panel structure 1 are arranged relative to each other along a third direction S3 and are fixedly connected to each other; the side enclosure inner panel structure 2 includes an A-pillar inner panel module 21, an inner panel middle section module 22 and at least two inner panel rear section modules 23 / 23' which are divided and connected along a first direction S1, and the inner panel middle section module 22 is configured to be able to selectively connect to one of the inner panel rear section modules 23 / 23'; wherein, the A-pillar inner panel module 21 is arranged corresponding to the side enclosure front portion 11, the inner panel middle section module 22 is arranged corresponding to the side enclosure middle portion 12, and the inner panel rear section module 23 / 23' is arranged corresponding to the side enclosure rear portion 13 / 13'. In this way, the inner panel rear section module 23 / 23' of the corresponding design length can be selected according to the size of the selected side panel outer panel structure 1 to be connected with the inner panel middle section module 22 and the A-pillar inner panel module 21, and the corresponding blocks can be combined and connected with the side panel outer panel structure 1 to form the body side of the required vehicle model; at the same time, the side panel inner panel structure 2 and the side panel outer panel structure 1 are adapted to each other, and can provide effective support for the side panel outer panel structure 1 and effectively transmit the load, thereby improving the collision performance and supporting capacity of the side panel assembly 10.

[0060] For example, Figure 8 and Fig. 9As shown, the side panel assembly 10 of the present embodiment is provided with a side panel outer panel structure 1 of a short-axle low-top cargo vehicle, and the side panel inner panel structure 2 is provided with an A-pillar inner panel module 21, an inner panel middle section module 22 and two inner panel rear section modules 23 / 23' with different design lengths in the first direction S1, wherein the inner panel rear section module 23 with a shorter design length corresponds to the length of the side panel rear portion 13 of the short-axle vehicle, and the inner panel rear section module 23' with a longer design length corresponds to the length of the side panel rear portion 13' of the long-axle vehicle; after the A-pillar inner panel module 21 and the inner panel middle section module 22 are fixedly connected by welding, the inner panel rear section module 23 with a shorter design length is fixedly connected to the side of the inner panel middle section module 22 away from the A-pillar inner panel module by welding, i.e., the side panel inner panel structure 2 of the short-axle vehicle is formed, and then the side panel inner panel structure 2 is fixedly connected to the side panel outer panel structure 1, i.e., the side panel assembly 10 of the short-axle vehicle is formed. In other embodiments, when the wheelbase requirement is a long axis, the inner panel rear section module 23' with a longer design length can be fixedly connected to the side of the inner panel middle section module 22 away from the A-pillar inner panel module by welding, that is, the side panel inner panel structure of the long axis vehicle model is formed, and it is fixedly connected to the side panel outer panel structure 1 of the corresponding vehicle model to form the side panel assembly of the long axis vehicle model. In this way, the A-pillar inner panel module 21 and the inner panel middle section module 22 of the short axis vehicle model and the long axis vehicle model can be used interchangeably, effectively improving the material utilization rate and the commonality rate.

[0061] It can be understood that the side panel inner structure 2 is the main supporting structure of the side panel assembly 10, and it needs to be connected to the side panel outer structure 1 outward, to the roof crossbeam 8 upward, and to the vehicle body 9 downward. Fig.11 and Fig.12As shown, for the conversion between high-roof and low-roof vehicle models, the structures with size changes are the side panel upper part and the roof cover of the side panel outer panel structure 1. Since the installation position of the roof cross beam 8 of the low-roof or high-roof cover remains unchanged in the second direction S2, the side panel inner panel structure 2 itself can remain unchanged in height size and can also support the low-roof or high-roof roof cross beam 8 in the second direction S2; and for the conversion between long-axis and short-axis vehicle models, in order to provide effective support for the side panel outer panel structure 1, in addition to the side panel outer panel structure 1, the side panel inner panel structure 2 should also be lengthened or shortened in the first direction S1 accordingly. Therefore, the A-pillar inner panel module 21 is arranged corresponding to the side panel front portion 11, which can be understood as the A-pillar inner panel module 21 corresponds to the length of the side panel front portion 11 in the first direction S1, and the upper and lower ends in the second direction S2 respectively correspond to the bottom height of the side panel front upper module 111 and the top height of the vehicle body in the area; similarly, the inner panel middle section module 22 is arranged corresponding to the side panel middle portion 12, which can be understood as the inner panel middle section module 22 corresponds to the length of the side panel middle portion 12 in the first direction S1, and the upper and lower ends in the second direction S2 respectively correspond to the bottom height of the side panel middle portion upper module 121 and the top height of the vehicle body floor in the area; the inner panel The rear section module 23 is arranged corresponding to the side panel rear portion 13, which can be understood as the inner panel rear section module 23 corresponding to the length of the side panel rear portion 13 in the first direction S1, and the upper and lower ends in the second direction S2 respectively correspond to the bottom height of the side panel rear upper module 131 and the top height of the vehicle body floor in the area; at the same time, the inner panel rear section module 23 corresponds to the length of the side panel rear portion 13 in the first direction S1, which can be understood as selecting the wheelbase size at the side panel rear portion 13, and then selecting the inner panel rear section module 23 of the corresponding design length to be connected to the side panel rear portion 13 and the inner panel middle section module 22, so that the side panel inner panel structure 2 and the side panel outer panel structure 1 can be adapted to each other.

[0062] In some embodiments, Figures 11 to 17 As shown, the modules of the side enclosure outer panel structure 1, the modules of the side enclosure inner panel structure 2, and the side enclosure outer panel structure 1 and the side enclosure inner panel structure 2 can be welded and connected by overlapping or butting, and a weld sealant 31 is provided between the overlapping surfaces or the butting surfaces. After the overlapping surfaces or the butting surfaces are sealed and connected by the weld sealant 31, the two are connected by spot welding; in this way, the stable connection of the connection between the modules can be guaranteed, and the waterproof and dustproof performance of the connection can be improved.

[0063] It can be understood that the above-mentioned overlapping connection method can be understood as one end of the two used for connection is staggered and connected in a direction perpendicular to the end plate surface, and the staggered contact surface is the overlapping surface; the above-mentioned butt connection method can be understood as one end of the two used for connection is in relative alignment contact, and the end surface of one end of the two used for connection is extended with a flange 16 in a direction perpendicular to the end plate surface, and the contact surface of the flange 16 is the butt surface. It can also be understood that the overlapping connection method can improve the bearing capacity of the connection in the direction perpendicular to the plate surface; the butt connection method can make the connection at the side without the flange 16 extending flat and more beautiful; the flange 16 can also be set on the end surface of either end and overlapped with the other end through the flange 16, while maintaining the stability of the connection, the side without the flange 16 extending can also be made flat. It can be selected according to the functional use of the connection.

[0064] For example, Fig.11 As shown, the exterior of the side enclosure rear upper module 131 and the side enclosure rear lower module 132 need to be displayed to the outside, so the two are connected in a butt-jointed manner and the flange 16 is arranged inward, and the butt-jointed surfaces are sealed by a weld sealant 31, and then the two are connected by spot welding, so that the connection between the two can be stable and the external connection can be smooth and flat; and since the side enclosure rear lower module 132 and the inner panel rear section module 23 do not have an external display surface, and the side enclosure inner panel structure 2 needs to provide structural support to the side enclosure outer panel structure 1, the side enclosure rear lower module 132 and the inner panel rear section module 23 are connected in an overlapping manner, and the overlapping surfaces are sealed by a weld sealant 31, and then the two are connected by spot welding, so that the connection stability between the two can be improved.

Specifically, in order to improve the side impact performance and structural strength of the side panel structure, a B-pillar cavity 51 is formed between the connection between the side panel front portion 11 and the side panel middle portion 12 and the side panel inner panel structure 2, a C-pillar cavity 52 is formed between the side panel middle portion 12 and the side panel rear portion 13 and the side panel inner panel structure 2, and a D-pillar cavity 53 is formed between the side of the side panel rear portion 13 away from the side panel middle portion 12 and the side panel inner panel structure 2; at the same time, since the various parts of the side panel outer panel structure 1 and the various modules of the side panel inner panel structure 2 are correspondingly arranged, the connection between the various parts of the side panel outer panel structure 1 and the connection between the various modules of the side panel inner panel structure 2 in the first direction S1 basically coincides, therefore, There are multi-section and multi-module connections at the positions of the B-pillar cavity 51, the C-pillar cavity 52 and the D-pillar cavity 53. By arranging the reinforcement 4 between the side outer panel structure 1 and the side inner panel structure 2, that is, in the corresponding B-pillar cavity 51, the C-pillar cavity 52 and the D-pillar cavity 53, and the plate surface shape of the reinforcement 4 is adapted to the concave and convex shape of the side inner panel structure 2 in the area, and the side outer panel structure 1 and the side inner panel structure 2 are connected by three-layer welding around the reinforcement 4, on the one hand, the heat input can be reduced, the deformation can be reduced, and the probability of defects can be reduced. On the other hand, the connection stability and bearing capacity of the side outer panel structure 1 and the side inner panel structure 2 can be significantly improved, and effective support can be provided for the top cover crossbeam 8.

[0066] Preferably, Fig.10 As shown, the overall shape of the reinforcement 4 can be T-shaped, with one end of the upper side extending along the first direction S1 or the two ends of the upper side extending horizontally along the first direction S1 respectively, and the lower side extending downward along the second direction S2 to further improve the structural strength of the connection.

[0067] In some embodiments, Figure 7 and Fig.16As shown, the lower side of the upper end of the side panel front upper module 111 overlaps the upper end of the side panel middle lower module 122, and the upper side of the upper end of the side panel front upper module 111 is butt-jointed with the front end of the side panel middle upper module 121; a first reinforcement plate 6 is provided at the joint between the side panel front upper module 111 and the side panel middle upper module 121, one end of the first reinforcement plate 6 is welded to the side panel front upper module 111 and / or the side panel middle upper module 121, and the other end abuts against the side panel inner panel structure 2 and a shock-absorbing expansion glue 32 is provided on the abutting surface. Specifically, the first reinforcing plate 6 may be L-shaped, and the side thereof close to the side enclosure outer panel structure 1 is perpendicular to the plate surface of the side enclosure outer panel structure 1 and can be connected to the flange 16 of the side enclosure front upper module 111 and / or the side enclosure middle upper module 121 by spot welding, and the side thereof close to the side enclosure inner panel structure 2 is parallel to the plate surface of the side enclosure inner panel structure 2 and is bonded thereto, and the two are connected at the bonding surface by a shock-absorbing expansion adhesive 32. In this way, by providing the first reinforcing plate 6, the structural strength and connection stability of the seam connection between the side enclosure front upper module 111 and the side enclosure middle 12 can be improved.

[0068] In some embodiments, Figure 7 and Fig.17 As shown, the side enclosure middle lower module 122 is butted with the side enclosure rear lower module 132; a second reinforcing plate 7 is provided at the butt joint of the side enclosure middle lower module 122 and the side enclosure rear lower module 132, one end of the second reinforcing plate 7 is welded to the side enclosure middle lower module 122 and / or the side enclosure rear lower module 132, and the other end abuts against the side enclosure inner panel structure 2 and a shock-absorbing expansion adhesive 32 is provided on the abutting surface. Specifically, the second reinforcing plate 7 may be L-shaped, and the side thereof close to the side enclosure outer panel structure 1 is perpendicular to the plate surface of the side enclosure outer panel structure 1 and can be connected to the flange 16 of the side enclosure middle lower module 122 and / or the side enclosure rear lower module 132 by spot welding, and the side thereof close to the side enclosure inner panel structure 2 is parallel to the plate surface of the side enclosure inner panel structure 2 and abuts therewith, and the two are connected at the abutting surface by the shock-absorbing expansion adhesive 32. In this way, by providing the second reinforcing plate 7, the structural strength and connection stability of the seam connection between the side panel middle lower module 122 and the side panel rear lower module 132 can be improved.

The specific structural form of the connecting parts inside the module can be changed according to the design purpose of the side panel, such as whether there is a middle door design, etc., but it does not affect the aforementioned description of the position relationship of the module itself and the connection relationship between the modules.

[0070] In some embodiments, Figures 8 to 10 and Fig.18As shown, when the side panel assembly is a side panel assembly 10 without a middle door design, the inner panel middle section module 22 includes a first B-pillar inner panel 221, a first window frame skin 222, a first C-pillar inner panel 223 and at least one first support plate 224; the inner panel rear section module 23 includes a second window frame skin 231, a first D-pillar inner panel 232, a first rear wheel cover assembly 233 and at least one second support plate 234; wherein the lower end of the A-pillar inner panel module 21 can be connected to the vehicle body 9 by plug welding, the first B-pillar inner panel 221 is arranged along the second direction S2, and the upper ends of the first B-pillar inner panels 221 are respectively The upper end of the A-pillar inner panel module 21 and the front end of the first window frame skin 222 can be connected by spot welding, and the lower end thereof can be connected to the body floor 91 of the vehicle body 9 by plug welding; the first C-pillar inner panel 223 is arranged on the lower side of the rear end of the first window frame skin 222 along the second direction S2, and the upper end of the first C-pillar inner panel 223 is partially connected to the first window frame skin 222; the first support plate 224 is vertically fixed to the lower end of the first window frame skin 222 and connected downward to the body floor 91 of the vehicle body 9. In this embodiment, two first support plates 224 are provided, and the two first support plates 224 are connected to the vehicle body floor 91 of the vehicle body 9.

Similarly, when the second support plate 234 is provided in plurality, the lengths thereof in the second direction S2 may be different, and it is sufficient that they can be connected to the first rear wheel housing assembly 233 to provide support for the second window frame skin 231.

It only needs to move the rear wheel cover outer plate 2331 backward as needed, and adaptably replace the first connecting plate 2332 and the second connecting plate 2333, which effectively improves the material utilization rate and the universalization rate.

[0074] It is understandable that when the required vehicle type is a short-axle vehicle, Figure 8 and Fig.10 As shown, the first connecting plate of the first rear wheel cover assembly 233 can be integrally formed with the first C-pillar inner plate 223, and the rear wheel cover outer plate 2331 is directly connected to the first C-pillar inner plate 223, saving materials and reducing deadweight; when the required vehicle model is a long-axis vehicle model, such as Fig. 9 and Fig.18 As shown, the front end of the first connecting plate 2332 can be extended and connected to the first C-pillar inner plate 223 to improve the structural strength and connection stability of the first rear wheel cover assembly 233.

In this embodiment, two third support plates 238 of different lengths are provided, and the two third support plates 238 are spaced apart along the first direction S1 to provide effective support for the third window frame skin 235. In this way, the overall structural strength and connection stability of the side inner panel structure 2 can be ensured through the above connection method, and effective support can be provided for the side outer panel structure 1 and the top cover crossbeam 8.
