Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of vehicle manufacturing, in particular to a vehicle roof assembly and a vehicle frame comprising the same. Background Art
[0002] A vehicle's roof is a covering on top of the vehicle body, typically made of metal or composite materials. It provides protection for passengers from wind, rain, and sun, and creates a relatively enclosed and safe riding space. Existing vehicle roof assemblies typically also include a gutter structure. The gutter structure is a grooved structure located at the edge of the vehicle's roof, typically located along the vehicle's side. A vehicle's side is the primary structural element on the side of the vehicle, typically including the front and rear door frames, door sills, A-pillars, B-pillars, C-pillars, rear quarter panels, and wheel arches.
[0003] The gutter structure directs rainwater and car wash water from the roof to a specific drain outlet, preventing water from accumulating on the roof and potentially damaging the vehicle structure. Traditional gutter structures, however, typically lack an upwardly curved flange, allowing rainwater to flow along the outside of the side panels and between the doors. Once the doors are opened, rainwater can easily flow into the vehicle.
[0004] Currently, there is a type of trough structure with a flange on the market. This structure consists of reinforcing ribs forming the main body of the trough structure, with decorative strips or plastic clips attached to the reinforcing ribs to form an upwardly raised flange. This trough structure with a flange is complex to assemble, heavy, and expensive, which in turn results in the top cover assembly also being complex to assemble, heavy, and expensive. Summary of the Invention
[0005] The object of the present invention is to provide a roof cover assembly for a vehicle, which can guide the flow of rainwater and is not easy to overflow, is easy to assemble, is light in weight and has low cost.
[0006] Another object of the present invention is to provide a vehicle frame comprising the above-mentioned roof cover assembly, which can guide the flow of rainwater and is not easy to overflow, is easy to assemble, is light in weight and has low cost.
[0007] The roof assembly of a vehicle provided by the present invention includes a roof and a top water diversion structure. The roof is convex and is arranged to cover the side of the vehicle. The edge of the roof has a roof flange extending outward in the horizontal direction. The top water diversion structure is fixedly connected to the side and has a mounting groove opening upward. The mounting groove is arranged around the side along the circumference of the side perpendicular to the height direction, and the bottom surface of the mounting groove is arranged parallel to the top cover flange. The top cover flange is inserted into the mounting groove and fixed to the bottom surface of the mounting groove in parallel by spot welding. The outer surface of the roof and the groove surface of the mounting groove form a water diversion groove that can block water on both the inside and outside sides in the horizontal direction.
[0008] By providing a top water diversion structure in the top cover assembly, rainwater can be directed and prevented from overflowing, making the top cover assembly easy to assemble. Since the top water diversion structure is simple, compact, light and low-cost, the top cover assembly is also light and low-cost.
[0009] In another exemplary embodiment of a vehicle roof assembly, a water channel is arranged to be higher at the rear and lower at the front, with both ends of the channel terminating at the left and right edges of the front windshield. The bottom of the channel is tilted inward and downward horizontally. This facilitates the roof assembly to direct rainwater toward the front windshield and prevent overflow.
[0010] In another schematic embodiment of the roof assembly of a vehicle, the top water diversion structure includes: a rear splicing body, two side splicing bodies, two rear corners and two front corners. The rear splicing body is arranged on the rear side of the side panel and extends in the width direction of the vehicle body. The two side splicing bodies are respectively arranged on the left and right sides of the side panel and extend in the length direction of the vehicle body. The rear ends of the two side splicing bodies are connected to the two ends of the rear splicing body through the two rear corners. The two front corners are respectively connected to the front ends of the two side splicing bodies. Among them, the rear splicing body, the side splicing bodies, the rear corners and the front corners respectively surround different sections of the installation groove. The use of a segmented splicing structure is conducive to the processing, storage and transportation of the top water diversion structure, and is convenient for replacing damaged splicing structures during use, with low cost.
[0011] In another exemplary embodiment of a vehicle roof assembly, the roof assembly further comprises a plurality of reinforcing ribs. Each rib is fixedly connected to the roof and has a connecting portion that mates parallel to the lower surface of the roof flange. The connecting portion is superimposed parallel to the roof flange and the bottom surface of the groove and is fixedly connected by spot welding. This helps improve the mechanical performance of the roof assembly.
[0012] In another exemplary embodiment of a vehicle roof assembly, the inner edges of the side panels are bent upward to allow them to overlap parallel to the upwardly angled outer surfaces of the side panels and be securely connected to the side panels via spot welding. The side panels are spot welded to the roof and side panels at different planes, improving weld quality and reducing welding difficulty.
[0013] In another exemplary embodiment of a vehicle roof assembly, the side panels include an upper side panel portion and a lower side panel portion. The inner edge of the rear panel portion can be parallel and overlapped between the edges of the upper and lower side panels, and the upper and lower side panels are fixedly connected by spot welding. In another exemplary embodiment of the vehicle roof assembly, at least one of the rear panel portion, the side panel portion, the rear corner, and the front corner portion has a horizontal outer edge formed with a hem that folds back into the mounting groove. This simplifies the assembly process, improves assembly efficiency, and reduces process costs.
[0014] In another exemplary embodiment of a vehicle roof assembly, one end of the rear corner overlaps the end of the rear assembly, while the other end of the rear corner overlaps the rear end of the side assembly. The top water diversion structure also includes a retaining clip. The retaining clip is used to clamp the overlapping structures and includes two clamping legs. The two clamping legs utilize the elastic restoring force generated by the elastic deformation of the retaining clip to relatively clamp the overlapping structures, thereby facilitating the clamping of the overlapping structures.
[0015] In another exemplary embodiment of a vehicle roof assembly, the front end of the side assembly overlaps one end of the front corner. The top water diversion structure also includes an edge seal. The edge seal wraps around the retaining wall of the front corner located outside the water diversion channel and clamps the overlapping portion of the front corner and the side assembly. The edge seal includes: an edge seal body, a positioning portion, a plurality of limiting portions, and a pressing portion. The edge seal body wraps around the retaining wall of the front corner from four angles: the front, the outside, the bottom, and the top. The positioning portion protrudes downward from the inner surface of the edge seal body along the height of the vehicle body. The retaining wall of the front corner has a positioning opening. The positioning portion can extend into the positioning opening to position the edge seal when the edge seal is installed on the front corner. The plurality of limiting portions protrude downward from the inner surface of the edge seal body along the height of the vehicle body. The plurality of limiting portions can limit the relative horizontal position of the retaining wall and the edge seal when the edge seal is installed on the front corner. The clamping portion protrudes downward from the inner surface of the edge banding body along the vehicle body's height and applies horizontal force to the retaining wall of the side assembly located outside the water channel, thereby horizontally clamping the overlapping portion of the side assembly and the front corner together with the edge banding body. This effectively protects the front corner and clamps the overlapping structure.
[0016] The present invention further provides a vehicle frame comprising the aforementioned top cover assembly and a side panel. The top cover is mounted on the side panel. A top water diversion structure is fixedly connected to the side panel. A mounting groove is disposed around the side panel along a circumference perpendicular to the height direction of the side panel.
[0017] The vehicle frame is configured with the top cover assembly, which can guide the flow of rainwater and prevent it from overflowing, making the vehicle frame easy to assemble, light in weight and low in cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0029] In order to have a clearer understanding of the technical features, purposes and effects of the invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.
[0030] In this document, “illustrative” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “illustrative” should not be interpreted as a more preferred or more advantageous technical solution.
[0031] Figure 1 It is a perspective view showing a schematic embodiment of a top cover assembly. Figure 2 for Figure 1 The cross-sectional view of the structure shown, with the cross-sectional plane parallel to the height direction, the height direction is Figure 1 and Figure 2 From top to bottom. Figure 1 and Figure 2 The roof assembly of the vehicle includes a roof 10 and a top water diversion structure 20. The roof 10 is convex and is covered on the side 200 of the vehicle. Figure 1 The structure shown is from the front windshield 300 to the rear side of the vehicle body. In order to clearly show the top cover assembly, Figure 1 Only a portion of the side periphery 200 on the right side of the drawing is shown.
[0032] See also Figure 2 , the top water diversion structure 20 is respectively fixedly connected to the top cover 10 and the side panel 200 and has a mounting groove 21. The mounting groove 21 opens upward. The edge of the top cover 10 has a top cover flange 11 extending outward in the horizontal direction. The horizontal direction is perpendicular to the height direction, and both are relative to the vehicle itself. The mounting groove 21 is arranged around the side panel 200 along the circumference of the side panel 200 perpendicular to the height direction. The groove bottom surface 211 of the mounting groove 21 is arranged parallel to the top cover flange 11. The top cover flange 11 is inserted into the mounting groove 21 and fixed in parallel to the groove bottom surface 211 of the mounting groove 21 by spot welding. In a specific embodiment, the minimum welding edge width of the groove bottom surface 211 and the top cover flange 11 is 9 mm to achieve high-quality welding.
[0033] The outer surface of the top cover 10 and the groove surface of the mounting groove 21 form a water diversion groove 30 that can block water on both sides in the horizontal direction. Figure 2 As shown, the top water diversion structure 20 has a retaining wall 212, which together with the top cover 10 forms a water diversion trough 30 with both inner and outer water retaining, with the retaining wall 212 on the outside and the top cover 10 on the inside. Figure 2 As shown, the bottom surface 211 of the mounting groove 21 is tilted inward and downward in the horizontal direction, as shown in FIG. Figure 2As shown in FIG, it is slightly tilted downward from left to right, so when guiding rainwater, it is beneficial to guide the rainwater to the right side (top cover 10 side) to avoid overflowing from the left side (blocking wall 212 side) when there is too much rainwater.
[0034] Therefore, by setting up a top water diversion structure in the top cover assembly, the rainwater flow can be guided and not easily overflowed, making the top cover assembly easy to assemble; since the top water diversion structure is simple, compact, light in weight and low in cost, the top cover assembly is also light in weight and low in cost.
[0035] The gutter 30 is configured to be higher at the rear and lower at the front, with its ends terminating at the left and right edges of the front windshield 300. This facilitates the gravity-driven flow of rainwater toward the windshield, which, in turn, has its own independent rainwater diversion and drainage system. Rainwater flows along the surface of the windshield into the gutter below it, and is then discharged through a dedicated outlet.
[0036] Figure 3 FIG. 1 is a schematic diagram of a top water diversion structure. In the schematic embodiment, see Figure 2 and Figure 3 The top water diversion structure 20 includes a rear splicing body 22, two side splicing bodies 23, two rear corners 24 and two front corners 25. The rear splicing body 22 is arranged on the rear side of the side panel 200 and extends in the width direction of the vehicle body. The two side splicing bodies 23 are respectively arranged on the left and right sides of the side panel and extend in the length direction of the vehicle body. The rear ends of the two side splicing bodies 23 are connected to the two ends of the rear splicing body 22 through the two rear corners 24. The two front corners 25 are respectively connected to the front ends of the two side splicing bodies 23, and the ends of the two front corners 25 terminate at the left and right edges of the front windshield 300. The rear splicing body 22, the side splicing bodies 23, the rear corners 24 and the front corners 25 respectively form different sections of the installation groove 21. This exemplary embodiment adopts a segmented splicing structure, which is convenient for processing, storing and transporting the top water diversion structure, and is also convenient for replacing damaged splicing structures during use, and the cost is also lower. In other exemplary embodiments, the top water diversion structure 20 may be spliced in other forms, or may be an integrally formed structure.
[0037] Figure 2 The top water diversion structure 20 shown is Figure 3 The side joint body 23 section on the left side of the middle. Except for the rear joint body 22, the connection method of the remaining joint structures of the top water diversion structure 20 and the top cover 10 and the side wall 200 is the same as that of the top cover 10 and the side wall 200. Figure 2 Same as displayed.
[0038] See also Figure 2In the exemplary embodiment, the edge of the retaining wall 212 of the top water diversion structure 20 in this section also has a folded edge that folds back into the mounting groove 21. The retaining wall 212 is an external protrusion. According to the automotive industry's regulations on external protrusions, the upper edge of the retaining wall 212 must be smoothly rounded; otherwise, it must be covered with a safety trim. Therefore, the edging of the retaining wall 212 helps simplify the assembly process, improve assembly efficiency, and reduce process costs. The edges of the retaining wall 212 of the rear assembly 22, the other side assembly 23, the rear corner 24, and the front corner 25 can also have a folded edge that folds back into the mounting groove 21. The height of the edging is 5 mm to 12 mm.
[0039] See also Figure 2 In the exemplary embodiment, the inner edge (i.e. Figure 2 The right edge (shown) is bent upward, allowing it to overlap parallel to the upwardly angled outer surface of the side panel 200 and be securely connected to the side panel 200 via spot welding. The side panels are spot welded to the top cover and side panels at different planes, improving welding quality and reducing welding difficulty. Similarly, the other side panels 23, rear corner 24, and front corner 25 can be spot welded to the top cover 10 and side panel 200 at different planes.
[0040] It should be noted that the distance between the end edge of the top cover flange 11 and the edge of the retaining wall 212 is 1 mm to 3 mm, and can be sealed by applying a layer of glue.
[0041] Figure 4 for Figure 1 The cross-sectional view of the structure shown, with the cross-sectional plane parallel to the height direction, the height direction is Figure 1 and Figure 2 In the direction from top to bottom. Figure 4 The top water diversion structure 20 shown is Figure 3 The left side assembly 23. The top cover assembly also includes several reinforcing ribs 26. The number of reinforcing ribs 26 is configured according to the actual situation of each vehicle model. Figure 4 , the reinforcing ribs 26 are fixedly connected to the top cover 10. Each reinforcing rib 26 has a connecting portion 261 that is parallel to and fits in with the lower surface of the top cover flange 11. The connecting portion 261 is parallel and overlapped between the top cover flange 11 and the groove bottom surface 211 and is fixedly connected by spot welding. The side assembly 23 on the right side is connected to the top cover 10 and the side panel 200 at the reinforcing rib. Figure 4 Since the reinforcing ribs 26 are usually across the left and right sides of the side panel, the rear joint 22 , the rear corner 24 and the front corner 25 are usually not connected to the reinforcing ribs 26 .
[0042] Figure 5 for Figure 1The cross-sectional view of the structure shown, with the cross-sectional plane parallel to the height direction, the height direction is Figure 1 and Figure 2 From top to bottom. Figure 5 The side panel 200 includes an upper side panel portion 210 and a lower side panel portion 220. The inner edge of the rear splicing body 22 can be overlapped parallel to the edge of the upper side panel portion 210 and the edge of the lower side panel portion 220, and the upper side panel portion 210 and the lower side panel portion 220 are fixedly connected by spot welding.
[0043] In the exemplary embodiment, one end of the rear corner 24 overlaps the end of the rear splicing body 22 , and the other end of the rear corner 24 overlaps the rear end of the side splicing body 23 . The top water diversion structure 20 further includes four fixing clips 27 . Figure 6 A perspective view of the fixing clip. Figure 7 The number of the fixing clips 27 can be other numbers, and the number is determined according to the actual application scenario.
[0044] The retaining clip 27 holds the overlapping structures of the rear corner 24 and the side assembly 23, and the rear corner 24 and the rear assembly 24. The portion of the overlapping structure that belongs to the rear corner 24 does not have a retaining wall 212. The retaining wall 212 at the end of the rear assembly 22 and the retaining wall 212 at the end of the side assembly 23 each have an opening 214. The retaining clip 27 includes two upper and lower clamping legs 271 and an anti-slip rib 272. Each retaining clip 27 is inserted into the opening 214 in the retaining wall 212 via the anti-slip rib 272 to prevent the retaining clip 27 from sliding. The two clamping legs 271 utilize the elastic restoring force generated by the elastic deformation of the retaining clip 27 to relatively clamp the overlapping structures.
[0045] In an exemplary embodiment, see Figure 7 The rear corner 24 also has a positioning column 241, which can be inserted into a positioning hole opened in the top cover during the assembly process to locate the position of the top cover.
[0046] In the exemplary embodiment, the retaining wall 212 of the front corner 25 does not have an edge folded back into the mounting groove 21. Therefore, according to the regulations of the automotive industry regarding external protrusions, an edge sealing sleeve needs to be provided to ensure safety in use. Figure 8 This is a three-dimensional diagram of the edge banding sleeve. Figure 9 It is a schematic diagram for explaining the installation method of the edge sealing sleeve and the top water diversion structure.
[0047] See also Figure 8 and Figure 9The front end of the side joint 23 overlaps one end of the front corner 25. The top water diversion structure 20 also includes an edge sealing sleeve 28. The edge sealing sleeve 28 wraps around the retaining wall 212 of the front corner 25 and clamps the overlapping portion of the front corner 25 and the side joint 23.
[0048] The edge banding sleeve 28 includes an edge banding sleeve body 281, a positioning portion 282, two limiting portions 283 and a pressing portion 284. In other exemplary embodiments, the number of limiting portions can be determined according to the actual application scenario. The edge banding sleeve body 281 wraps around the retaining wall 212 of the front corner 25 from four angles: the front side, the outside, the bottom side and the top side. The positioning portion 282 is provided on the edge banding sleeve body 281 and protrudes downward from the inner surface of the edge banding sleeve body 281 along the height direction of the vehicle body. The height direction is Figure 8 and Figure 9 The retaining wall 212 of the front corner 25 defines a positioning opening 213. The positioning portion 282 extends into the positioning opening 213 to position the edge banding 28 when it is mounted on the front corner 25. The limiting portion 283 is provided on the edge banding body 281 and protrudes downward from the inner surface of the edge banding body 281 along the vehicle body height direction. Figure 9 Due to the angle, only one limiting portion 283 is shown. Limiting portion 283 limits the horizontal relative position of retaining wall 212 and edge sleeve 28 when edge sleeve 28 is positioned over front corner 25. A pressing portion 284 is provided on edge sleeve body 281, protruding downward from the inner surface of edge sleeve body 281 along the vehicle body's height. It applies a horizontal force to retaining wall 212 of side assembly 23, thereby horizontally clamping the overlapping structure between side assembly 23 and front corner 25 together with edge sleeve body 281. This effectively protects the front corner and clamps the overlapping structure.
[0049] In an exemplary embodiment, the assembly process of the top cover assembly includes: overlapping the two front corners and the two rear corners at the two ends of the two side splicing bodies in a stacking manner with the side splicing bodies at the bottom and the front corners and the rear corners at the top, using two edge sealing sleeves to clamp the structure in which the side splicing bodies and the front corners overlap each other, using two fixing clamps to clamp the structure in which the rear corners and the side splicing bodies overlap each other, overlapping the rear splicing body at the two ends of the two rear corners in a stacking manner with the rear corners at the bottom and the rear splicing body at the top, using two fixing clamps to clamp the structure in which the rear corners and the rear splicing body overlap each other to obtain a top water diversion structure, installing the top water diversion structure to the side surround by spot welding, inserting the positioning column of the rear corner into the positioning hole of the top cover to position the top cover, and installing the top cover flange into the installation groove by spot welding to complete the assembly of the top cover assembly.
[0050] The present invention further provides a vehicle frame comprising the aforementioned top cover assembly and a side panel 200. The top cover 10 is mounted on the side panel 200. A top water diversion structure 20 is fixedly connected to the side panel 200. Mounting grooves 21 are provided around the side panel 200 in a circumferential direction perpendicular to the height direction of the side panel 200.
[0051] The vehicle frame is configured with the top cover assembly, which can guide the flow of rainwater and prevent it from overflowing, making the vehicle frame easy to assemble, light in weight and low in cost.
