Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a sharp angle structure of a rear part of a vehicle side enclosure and a vehicle. Background Art

[0002] As the requirements for vehicle styling refinement continue to increase, existing vehicles usually set the sharp corners of the rear side panels to a smaller angle to make the rear side panel styling lines have a more refined visual effect.

[0003] Currently, the side panel outer panels are usually overlapped with vehicle-related structures, and sealant is applied at the overlapped joints to achieve a sealed connection between the side panel outer panels and these structures. However, due to the presence of small-angle sharp corners, a larger space is formed at the sharp corners of the side panel outer panels, which can easily cause the sealant applied into the sharp corner space to crack, thereby affecting the sealing of the sharp corner at the rear of the side panel. Utility Model Content

[0004] The problem solved by the utility model is how to improve the sealing performance at the sharp corner of the rear part of the side wall of the vehicle.

[0005] In order to solve the above problems, the utility model provides a vehicle side rear sharp corner structure and a vehicle.

[0007] Optionally, the pointed corner portion includes a first flange and a second flange that are intersectingly arranged, the first flange overlaps the lower side of the upper flange, and the second flange overlaps the upper side of the lower flange.

[0008] Optionally, a rounded corner is set at the intersection of the upper flange and the lower flange; a rounded corner is set at the intersection of the first flange and the second flange.

[0009] Optionally, it also includes a water trough assembly and a taillight installation assembly, wherein the water trough assembly is connected to the side outer panel, and the taillight installation assembly is arranged at the rear end of the water trough assembly and connected to the side extension panel.

[0010] Optionally, the upper side of the water flow channel assembly is provided with a first overlapping flange extending along the length direction of the upper flange, and the upper side of the taillight mounting assembly is provided with a second overlapping flange extending along the length direction of the upper flange, and the first overlapping flange and the second overlapping flange are respectively overlapped on the lower side of the upper flange.

[0011] Optionally, along the length direction of the upper flange, one end of the second overlapping flange extends to below the first flange and overlaps with the first flange, and the other end extends to below the first overlapping flange and overlaps with the first overlapping flange.

[0012] Optionally, the taillight mounting assembly includes a taillight mounting plate, a connecting plate and a lower mounting plate, the taillight mounting plate and the connecting plate are overlapped with the lower mounting plate respectively, the taillight mounting plate is connected to the side panel outer panel, the connecting plate is connected to the water flow channel assembly and the upper flange; the circumferential edges of the side panel extension plate are overlapped with the taillight mounting plate, the connecting plate and the lower mounting plate respectively.

[0016] The beneficial effects of the pointed angle structure of the rear part of the vehicle side panel of the utility model are as follows: by respectively arranging an upper flange and a lower flange on both sides of the side panel outer panel, and one end of the upper flange and one end of the lower flange intersecting to form a pointed angle notch, when the side panel outer panel and the side panel extension panel are assembled, the pointed angle notch can be used for the pointed angle portion of the side panel extension panel to be inserted; at the same time, by adding a side panel extension panel, and forming a pointed angle portion adapted to the shape of the pointed angle notch on the side panel extension panel, since the pointed angle portion is adapted to the shape of the pointed angle notch, the pointed angle portion can play a better filling effect on the pointed angle notch after being inserted into the pointed angle notch, and when the pointed angle portion is coated with glue for sealing, the sealant only needs to fill the gap between the pointed angle notch and the pointed angle portion, the required amount of glue coating is less and the bonding area is larger, which can avoid the situation that the sharp angle notch needs to be completely filled with sealant during glue coating and the sealant is easy to crack after coating, thereby improving the sealing performance at the sharp corner of the rear side panel. In addition, by forming a sharp corner portion on the side panel extension plate and inserting it into the sharp corner notch, the strength of the sharp corner structure at the rear of the vehicle side panel can also be improved.

[0026] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. Although some embodiments of the utility model are shown in the accompanying drawings, it should be understood that the utility model can be implemented in various forms and should not be interpreted as being limited to the embodiments described here.

It should also be noted that the aforementioned Z axis, Y axis, and X axis are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] The term "including" and its variations used in this article are open inclusions, that is, "including but not limited to"; the term "based on" means "based at least in part on"; the term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment"; the term "some embodiments" means "at least some embodiments"; the term "optionally" means "optional embodiments". The relevant definitions of other terms will be given in the following description. It should be noted that the concepts of "first", "second", etc. mentioned in the present utility model are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0029] It should be noted that the modifications of "one" and "plurality" mentioned in the present invention are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0030] In the related art, the rear part of the side panel outer panel usually has two upper and lower flanges, and the two flanges intersect at the sharp corner of the rear part of the side panel to form a sharp angle structure. For the sake of refinement in shape, the angle of the sharp angle structure is generally designed to be smaller, that is, the angle formed by the intersection of the two flanges is relatively small. Facing the smaller angle at the intersection of the two flanges, after the two flanges are overlapped with the vehicle-related structure, the angle space at the intersection can accommodate more sealant, so that when the sealant is applied, the glue will directly fill the space at the intersection, which is prone to cracking after curing, thereby affecting the sealing of the sharp corner of the rear part of the side panel.

[0031] In view of the problems existing in the above-mentioned related technologies, the utility model provides a vehicle side rear corner structure and a vehicle to improve the sealing performance of the side rear corner.

[0032] like Figure 1As shown, an embodiment of the utility model provides a pointed angle structure of the rear part of a vehicle side panel, comprising a side panel outer panel 1 and a side panel extension panel 2; an upper flange 11 and a lower flange 12 are respectively provided on both sides of the side panel outer panel 1, one end of the upper flange 11 and one end of the lower flange 12 intersect to form a pointed angle notch 15; a pointed angle portion 21 adapted to the shape of the pointed angle notch 15 is formed on the side panel extension panel 2, and the pointed angle portion 21 is inserted into the pointed angle notch 15.

[0033] It should be noted that the side outer panel 1 of the vehicle extends along the front-rear direction of the vehicle, that is, the upper flange 11 and the lower flange 12 of the side outer panel 1 also extend along the front-rear direction of the vehicle. Figure 1 As shown, one end of the upper flange 11 and one end of the lower flange 12 intersect to form a sharp-angled notch 15, which means that the rear end of the upper flange 11 intersects with the rear end of the lower flange 12, and the upper flange 11 and the lower flange 12 jointly define a notch structure at the intersection. It can be understood that the upper flange 11 and the lower flange 12 intersect to form the sharp-angled notch 15, and also form the sharp-angled shape of the vehicle appearance. It should be noted that the sharp-angled portion 21 adapted to the shape of the sharp-angled notch 15 does not require the sharp-angled portion 21 to be completely consistent with the size of the sharp-angled notch 15. The outline size of the sharp-angled portion 21 can be slightly smaller than the outline size of the sharp-angled notch 15 to avoid interference between the two when they are assembled. It should be noted that after the side outer panel 1 and the side extension panel 2 are assembled, glue can be applied between the sharp-angled notch 15 and the sharp-angled portion 21 to achieve sealing at the sharp corner.

[0034] Specifically, Figure 2 As shown, the side outer panel 1 may include an intersecting upper edge 13 and a lower edge 14, the upper flange 11 may be provided at the upper edge 13 of the side outer panel 1, and the lower flange 12 may be provided at the lower edge 14 of the side outer panel 1, the upper flange 11 and the lower flange 12 intersect, and a sharp-angle notch 15 is defined at the intersection of the upper edge 13 and the lower edge 14; Figure 3 As shown, a sharp corner portion 21 matching the shape of the sharp corner notch 15 is formed on the left side of the side extension plate 2 , and the sharp corner portion 21 is inserted into the sharp corner notch 15 .

[0035] In this embodiment, an upper flange 11 and a lower flange 12 are respectively provided on both sides of the side outer panel 1, and one end of the upper flange 11 and one end of the lower flange 12 intersect to form a sharp-angled notch 15. When the side outer panel 1 and the side extension panel 2 are assembled, the sharp-angled notch 15 can be inserted into the sharp-angled portion 21 of the side extension panel 2; at the same time, the side extension panel 2 is additionally provided, and a sharp-angled portion 21 matching the shape of the sharp-angled notch 15 is formed on the side extension panel 2. The shape of the opening 15 is adapted so that the sharp corner portion 21 can fill the sharp corner notch 15 after being inserted into the sharp corner notch 15. When the sharp corner portion 21 is sealed with glue, the sealant only needs to fill the gap between the sharp corner notch 15 and the sharp corner portion 21. The required amount of glue is small and the bonding area is large. It can avoid the situation that the sharp corner notch 15 needs to be completely filled with sealant during glue application and the sealant is easy to crack after glue application, thereby improving the sealing performance of the sharp corner of the rear side wall. In addition, by forming the sharp corner portion 21 on the side wall extension plate 2 and inserting it into the sharp corner notch 15, the strength of the sharp corner structure of the rear side wall of the vehicle can also be improved.

[0036] Alternatively, if Figure 3 As shown, the pointed corner portion 21 includes a first flange 211 and a second flange 212 that are intersectingly arranged, the first flange 211 overlaps the lower side of the upper flange 11 , and the second flange 212 overlaps the upper side of the lower flange 12 .

[0037] Specifically, Figure 4 and Figure 5 As shown, the first flange 211 can be along the length direction of the upper flange 11 (i.e. Figure 2 The second flange 212 can extend along the length direction of the lower flange 12 (i.e., the extension direction of the upper edge 13) and overlap with the lower side of the upper flange 11. Figure 2 The lower edge 14 extends in the extension direction of the lower edge 14 and overlaps with the upper side of the lower flange 12.

[0038] In this optional embodiment, the first flange 211 overlaps the upper flange 11, and the second flange 212 overlaps the lower flange 12, which can support the upper flange 11 and the lower flange 12 and prevent the upper flange 11 and the lower flange 12 from deforming, thereby improving the strength of the side outer panel 1; and, during the process of assembling the side extension plate 2 to the side outer panel 1, the first flange 211 can be moved along the upper flange 11 or the second flange 212 can be moved along the lower flange 12 until the sharp corner 21 enters the sharp corner notch 15, so as to provide a guiding effect on the assembly process, thereby improving the assembly efficiency of the sharp corner structure at the rear of the vehicle side panel.

[0039] Alternatively, if Figure 1 As shown, a rounded corner is set at the intersection of the upper flange 11 and the lower flange 12; a rounded corner is set at the intersection of the first flange 211 and the second flange 212.

[0040] Specifically, the radius of the upper flange 11 and the lower flange 12 can be different from the radius of the first flange 211 and the second flange 212. For example, the radius of the upper flange 11 and the lower flange 12 is 1-2mm, such as 1mm, 1.2mm or 2mm, and the radius of the first flange 211 and the second flange 212 is 2-3mm, such as 2mm, 2.5mm or 3mm.

[0041] In this optional embodiment, by setting the intersection of the first flange 211 and the second flange 212 as a rounded corner, it is possible to avoid the intersection of the first flange 211 and the second flange 212 being too sharp, which would cause interference between the intersection and the upper flange 11 or the lower flange 12 during the assembly of the side enclosure extension plate 2 to the side enclosure outer panel 1; and by setting the intersection of the upper flange 11 and the lower flange 12 and the intersection of the first flange 211 and the second flange 212 as rounded corners at the same time, the two rounded corners have a certain mutual positioning effect, so as to ensure the assembly accuracy of the side enclosure outer panel 1 and the side enclosure extension plate 2, and to improve the sealing of the sharp corners at the rear of the side enclosure.

[0042] Alternatively, if Figure 1 and Figure 4 As shown, the pointed structure at the rear of the vehicle side panel also includes a water trough assembly 3 and a taillight mounting assembly 4. The water trough assembly 3 is connected to the side panel outer panel 1, and the taillight mounting assembly 4 is arranged at the rear end of the water trough assembly 3 and is connected to the side panel extension plate 2.

[0043] It should be noted that the assembly process of the side panel outer panel 1, the side panel extension panel 2, the water channel assembly 3 and the taillight installation assembly 4 can be as follows: Figure 1 As shown, along the installation direction i, the side panel extension plate 2 is first welded to the taillight mounting assembly 4, and then the taillight mounting assembly 4 is welded to the water gutter assembly 3, and then the side panel extension plate 2, the water gutter assembly 3 and the taillight mounting assembly 4 are pressed against the side panel outer plate 1 from right to left (toward the positive direction of the Y axis), and then the side panel extension plate 2, the water gutter assembly 3 and the taillight mounting assembly 4 are moved backward (negative direction of the X axis) until the sharp corner 21 enters the sharp corner notch 15. During the backward movement process, the first flange 211 can be moved along the upper flange 11, which can guide the backward movement process of the side panel extension plate 2, the water gutter assembly 3 and the taillight mounting assembly 4, thereby improving the assembly efficiency.

[0044] In this optional embodiment, the water trough assembly 3 and the taillight installation assembly 4 are separated to avoid an integrated structure for the two, which is more conducive to the separate stamping and forming of the water trough assembly 3 and the taillight installation assembly 4 and reduces the processing difficulty.

[0045] Alternatively, if Figure 1 and Figure 3As shown, the upper side of the water flow channel assembly 3 is provided with a first overlapping flange 31 extending along the length direction of the upper flange 11, and the upper side of the taillight mounting assembly 4 is provided with a second overlapping flange 421 extending along the length direction of the upper flange 11, and the first overlapping flange 31 and the second overlapping flange 421 are overlapped on the lower side of the upper flange 11 respectively.

[0046] It should be noted that the upper flange 11 and the first overlapping flange 31 and the second overlapping flange 421 can be overlapped by, for example, spot welding. Figure 3 As shown, a second overlapping flange 421 can be provided on the upper side of the connecting plate 42 of the taillight mounting assembly 4. Specifically, the first overlapping flange 31 and the second overlapping flange 421 can be provided in sequence front to back, the first overlapping flange 31 can overlap the lower side of the front section of the upper flange 11, and the second overlapping flange 421 can overlap the lower side of the rear section of the upper flange 11.

[0047] In this optional embodiment, the first overlapping flange 31 is overlapped with the lower side of the upper flange 11, and the second overlapping flange 421 is overlapped with the lower side of the upper flange 11, so that the side outer panel 1, the water gutter assembly 3, and the taillight installation assembly 4 are connected to each other in pairs, which can ensure the connection strength of the three, thereby improving the structural strength of the sharp-angle structure at the rear of the vehicle side.

[0048] Alternatively, if Figure 1 and Figure 3 As shown, along the length direction of the upper flange 11 , one end of the second lap flange 421 extends to below the first flange 211 and overlaps with the first flange 211 , and the other end extends to below the first lap flange 31 and overlaps with the first lap flange 31 .

[0049] Specifically, the portion of the second lap flange 421 located between the first lap flange 211 and the first lap flange 31 can be arched so that the upper side surface of the portion of the second lap flange 421 located between the first lap flange 211 and the first lap flange 31 is coplanar with the upper side surface of the first flange 211 and the upper side surface of the first lap flange 31. Thus, when the upper flange 11 overlaps with the first lap flange 31, the second lap flange 421, and the first flange 211, the lower side surface of the upper flange 11 can simultaneously fit with the upper side surface of the first lap flange 31, the upper side surface of the second lap flange 421, and the upper side surface of the first flange 211 to achieve better sealing effect and connection strength.

[0050] Specifically, the first overlapping flange 31 , the second overlapping flange 421 and the first flange 211 are respectively sealed and connected to the upper flange 11 by means of sealant.

[0051] In this optional embodiment, by extending one end of the second lap flange 421 to below the first flange 211 and overlapping with the first flange 211, it is possible to avoid the second lap flange 421 extending above the first flange 211 and affecting the overlap between the first flange 211 and the upper flange 11, which is more conducive to the sealing at the sharp corner of the rear portion of the side panel; in addition, if the other end of the second lap flange 421 is extended to above the first lap flange 31, it is necessary to bend the end of the first lap flange 31 close to the second lap flange 421 downward to below the second lap flange 421. In this embodiment, by extending the other end of the second lap flange 421 to below the first lap flange 31 and overlapping with the first lap flange 31, the bending process of the end of the first lap flange 31 can be omitted, which relatively reduces the processing steps and reduces the processing complexity.

[0052] Alternatively, if Figure 4 and Figure 6 As shown, the taillight mounting assembly 4 includes a taillight mounting plate 41, a connecting plate 42 and a lower mounting plate 43, the taillight mounting plate 41 and the connecting plate 42 are overlapped with the lower mounting plate 43 respectively, the taillight mounting plate 41 is connected to the side outer panel 1, and the connecting plate 42 is connected to the water flow channel assembly 3 and the upper flange 11; the circumferential edges of the side extension plate 2 are overlapped with the taillight mounting plate 41, the connecting plate 42 and the lower mounting plate 43 respectively.

[0053] Specifically, Figure 3 As shown, the taillight mounting assembly 4 needs to install the taillight, and is connected to the water trough assembly 3, and is also connected to the side panel outer panel 1 and the side panel extension panel 2. It has a complex shape and is difficult to stamp. In this embodiment, the taillight mounting assembly 4 is composed of three parts: a taillight mounting plate 41, a connecting plate 42 and a lower mounting plate 43. Each part is stamped separately, which can avoid the problem of difficulty in stamping an integrated arrangement, and is beneficial to reducing the difficulty of processing. In addition, the taillight mounting plate 41, the connecting plate 42 and the lower mounting plate 43 are overlapped with the side panel extension panel 2 along the circumference of the side panel extension panel 2, which is beneficial to ensure the stability of the side panel extension panel 2 and improve the connection stability between the three parts.

[0054] like Figure 4As shown, in the taillight mounting assembly 4 of this embodiment, the taillight mounting plate 41 is connected to the side outer panel 1 and the side extension panel 2 respectively, and is used to mount the taillight; the connecting plate 42 is used to connect to the water trough assembly 3 and the upper flange 11 of the side outer panel 1, and the first flange 211 of the side extension panel 2. Specifically, the connecting plate 42 can be provided with a second overlapping flange 421, and the second overlapping flange 421 overlaps with the first overlapping flange 31 of the water trough assembly 3, the upper flange 11 of the side outer panel 1, and the first flange 211 of the side extension panel 2; the lower mounting plate 43 is connected to the taillight mounting plate 41, the connecting plate 42, and the side extension panel 2 respectively. Specifically, the upper part of the lower mounting plate 43 overlaps with the lower part of the taillight mounting plate 41, the lower flange of the connecting plate 42, and the lower part of the side extension panel 2. It should be noted that the plates can be connected by, for example, spot welding.

[0055] In this optional embodiment, the taillight mounting assembly 4 is divided into a taillight mounting plate 41, a connecting plate 42 and a lower mounting plate 43. When the taillight mounting plate 41, the connecting plate 42 and the lower mounting plate 43 are integrally arranged, the taillight mounting assembly 4 constitutes a deep cavity component, which is difficult to be formed by stamping. The divided arrangement allows each part of the taillight mounting assembly 4 to be processed separately, which is easier to stamp. By overlapping the circumferential edges of the side panel extension plate 2 with the taillight mounting plate 41, the connecting plate 42 and the lower mounting plate 43 respectively, different parts of the circumferential side of the side panel extension plate 2 can be connected to the three panels of the taillight mounting assembly 4 respectively. After the panels of the taillight mounting assembly 4 are connected to the gutter assembly 3 and the side panel outer panel 1, the above-mentioned connection relationship can ensure the stable position relationship of the side panel extension plate 2 relative to the side panel outer panel 1, thereby ensuring that the sharp corner portion 21 is stably plugged into the sharp corner notch 15, further improving the sealing at the sharp corner of the rear part of the side panel.

[0056] In the related art, the angle between the upper flange 11 and the side outer panel 1 is usually set to about 90°. At a 90° angle, if a small angle is to be formed at the sharp corner, it will make the sharp corner difficult to stamp and the welding gun difficult to enter, thereby affecting the stamping forming and weldability.

[0057] Therefore, optionally, Figure 7 As shown, in the cross section of the side outer panel 1 perpendicular to the front-rear direction of the vehicle, the extension direction of the upper flange 11 is parallel to the left-right direction of the vehicle or the extension direction of the upper flange 11 is inclined upward relative to the left-right direction of the vehicle.

[0058] It should be noted that if Figure 7As shown, the plate surface of the side outer panel 1 often has a certain angle with the up-down direction of the vehicle, that is, the plate surface of the side outer panel 1 gradually tilts toward the outside of the vehicle from top to bottom. Therefore, when the extension direction of the upper flange 11 in the cross section of the side outer panel 1 perpendicular to the front-to-back direction of the vehicle is parallel to the left-right direction of the vehicle or tilted upward relative to the left-to-right direction of the vehicle, the angle between the upper flange 11 and the side outer panel 1 (or the folding angle of the upper flange 11 relative to the side outer panel 1) is greater than 90°, which is not only more conducive to stamping at sharp corners, but also more conducive to the entry of welding guns. For example, the front-to-back direction of the vehicle is Figure 1 The X-axis direction is shown, and the left and right directions of the vehicle are Figure 1 The Y-axis direction shown, the up and down direction of the vehicle is Figure 1 The Z-axis direction is shown.

[0059] In this optional embodiment, when the extension direction of the upper flange 11 in the cross section of the side outer panel 1 perpendicular to the front-to-rear direction of the vehicle is parallel to the left-right direction of the vehicle or inclined upward relative to the left-right direction of the vehicle, the angle between the upper flange 11 and the side outer panel 1 will be much larger than 90°, which is more conducive to stamping at sharp corners and also more conducive to the entry of the welding gun, thereby ensuring the smooth stamping and welding of small-angle sharp corners of the side outer panel 1.

[0060] Alternatively, if Figure 7 As shown, the angle between the extension direction of the upper flange 11 and the left-right direction of the vehicle is less than or equal to 8°.

[0061] It is understandable that if Figure 7 As shown, the angle between the extension direction of the upper flange 11 and the left-right direction of the vehicle is less than or equal to 8°, that is, when the extension direction of the upper flange 11 in the cross section of the side outer panel 1 perpendicular to the front-rear direction of the vehicle is inclined upward relative to the left-right direction of the vehicle, the inclination angle θ of the extension direction of the upper flange 11 relative to the left-right direction of the vehicle is less than or equal to 8°, for example, the inclination angle θ is 4° or 8°.

[0062] In this optional embodiment, by limiting the angle between the extension direction of the upper flange 11 and the left-right direction of the vehicle to less than or equal to 8°, the formability and welding convenience of the small-angle sharp corners of the side outer panel 1 can be more effectively ensured.

[0063] A vehicle provided by an embodiment of the utility model comprises the vehicle side rear sharp corner structure as described above.

[0064] Specifically, the vehicle may be a new energy vehicle.

[0065] In this embodiment, the sharp angle structure of the rear part of the vehicle side panel of the vehicle is formed by respectively arranging an upper flange 11 and a lower flange 12 on both sides of the side panel outer panel 1, and one end of the upper flange 11 and one end of the lower flange 12 intersect to form a sharp angle notch 15. When the side panel outer panel 1 and the side panel extension panel 2 are assembled, the sharp angle notch 15 can be inserted into the sharp angle portion 21 of the side panel extension panel 2; at the same time, by adding the side panel extension panel 2, and forming a sharp angle portion 21 on the side panel extension panel 2 that matches the shape of the sharp angle notch 15, due to the sharp angle The shape of the portion 21 is adapted to the sharp-angled notch 15, so that after the sharp-angled notch 15 is inserted into the sharp-angled notch 15, the sharp-angled notch 15 can be filled well. When the sharp-angled notch 21 is sealed with glue, the sealant only needs to fill the gap between the sharp-angled notch 15 and the sharp-angled notch 21. The required amount of glue is small and the bonding area is large, which can avoid the situation that the sharp-angled notch 15 needs to be completely filled with sealant during glue application and the sealant is easy to crack after glue application, thereby improving the sealing performance of the sharp corner of the rear side wall. In addition, by forming the sharp-angled portion 21 on the side wall extension plate 2 and inserting it into the sharp-angled notch 15, the strength of the sharp-angled structure of the rear side wall of the vehicle can also be improved.
