[0030] Based on the background technology, the problem of poor hiding effect of the external water cut of existing car doors is pointed out. The present application provides a fixing structure of the external water cut of a car door, which aims to install the external water cut as a whole on the inner side of the car door to reduce the exposed area of the external water cut on the car door, thereby enhancing the hiding effect of the external water cut.
[0031] Specifically, Figures 1 to 3 As shown, the outer water cut fixing structure of the vehicle door of the present application includes a door outer panel 1, a reinforcement plate 2 and an outer water cut. Among them, one side of the door outer panel 1 has an inwardly folded edge structure 11, one side of the reinforcement plate 2 is fixed to the inner side of the edge structure 11, and a mounting groove for accommodating the outer water cut is formed on the reinforcement plate 2. The outer water cut includes a strip body 30 and a first lip 31 and a second lip 32 formed on the same side of the strip body 30. The strip body 30 is fixed in the mounting groove, and one side of the first lip 31 abuts against the outer side of the edge structure 11. In the state of installation, only the surface of the first lip 31 of the outer water cut is exposed on one side of the door outer panel 1, thereby reducing the overall exposed area of the outer water cut, greatly enhancing the hiding effect of the outer water cut.
[0032] The outer water cut fixing structure of the vehicle door of the present application is described in detail below in conjunction with two specific embodiments.
[0033] Embodiment 1
[0034] like Figure 1 and Figure 2 As shown, after the edge structure 11 of the door outer panel 1 in the embodiment of the present application is folded inwardly in the horizontal direction, the cross section of the edge structure 11 forms an N-shaped structure, and the width of the edge structure 11 ( Figure 2 In the horizontal direction, the side edge of the reinforcing plate 2 is embedded in the inner side of the edging structure 11, and the side edge of the reinforcing plate 2 is fastened to the door outer panel 1 by pressing the edging structure 11 of the door outer panel 1. The reinforcing plate 2 extends from the edging structure 11 to the inner side of the door to form a mounting groove with a stepped structure that can accommodate the outer water cut.
[0035] like Figure 2As shown, in the embodiment of the present application, the outer water cut includes a horizontally placed strip body 30 and a first lip 31 and a second lip 32 formed on the upper side of the strip body 30 in sequence, and the outer water cut also includes a third lip 33 formed on the lower side of the strip body 30. Among them, the state of the outer water cut includes an unextruded state 32a and an extruded state 32b, and the second lip 32 remains separated from the first lip 31 in the unextruded state 32a. When the strip body 30 of the outer water cut is fixed in the mounting groove of the reinforcing plate 2, the lower side edge of the first lip 31 abuts against the horizontal outer side edge of the edging structure 11 of the door outer panel 1.
[0036] like Figure 2 As shown, the cross section of the first lip 31 of the outer water cut in the embodiment of the present application has a T-shaped structure, and the head width of the T-shaped structure ( Figure 2 w2) is 4 mm, one side of the T-shaped structure is against the outside of the edging structure 11, and the end of the second lip 32 and the end of the third lip 33 of the outer water cut both have a barb structure.
[0037] It is understandable that the vehicle door includes a vehicle door glass. When the vehicle door is completely assembled, the outer water cut is fixed in the mounting groove on the reinforcing plate 2, and the second lip 32 and the third lip 33 of the outer water cut are tightly pressed against the outer surface of the vehicle door glass in horizontal upper and lower positions. Among them, after the second lip 32 of the outer water cut is squeezed by the vehicle door glass, the second lip 32 of the outer water cut undergoes elastic deformation in the squeeze state 32b so that the barb structure of the second lip 32 is pressed against the upper side of the T-shaped structure. That is, the first lip 31 of the outer water cut is clamped and squeezed and fixed between the edging structure 11 of the vehicle door panel and the second lip 32 of the outer water cut, and the head surface of the T-shaped structure is exposed to the outside and remains flush with the surface of the door outer panel 1.
[0038] It should be noted that when the user pays attention to the car door from the outside, most of the structure of the outer water cut is installed and hidden on the inner side of the reinforcing plate 2, and only the surface of the first lip edge 31 of the outer water cut is exposed on the side of the door outer panel 1. That is, the head surface of the T-shaped structure is exposed on the outside of the car door and is flush with the surface of the door outer panel 1, thereby greatly reducing the exposed area of the outer water cut on the door outer panel 1 and the user's attention, enhancing the hiding effect of the outer water cut and improving the user experience.
[0039] like Figure 2 As shown, one side of the first lip 31 of the outer water cut in the embodiment of the present application is sealed and connected to the edge structure 11. That is, the side below the head of the T-shaped structure and the outer end of the edge structure 11 horizontal to the door outer panel 1 are sealed with sealant.
[0040] It is understandable that when the glass encounters rain or the car is washed, the water flow on the door glass directly passes through the head surface of the first lip 31 and flows to the surface of the door outer panel 1, avoiding the water flow from the gap between the edging structure 11 of the door outer panel 1 and the first lip 31 of the outer water cut into the side of the reinforcing plate 2, thereby avoiding erosion damage to the door assembly and improving the waterproof sealing performance of the door.
[0041] like Figure 2 As shown, in the embodiment of the present application, the outer water cut also includes a frame 4, which is embedded and fixed in the strip body 30, and the frame 4 is an inverted and inclined L-shaped structure, and the frame 4 is a steel bar or an aluminum alloy bar. It can be understood that the outer water cut and the frame 4 are wrapped in the strip body 30 using a rubber injection molding process. The frame 4 can support the first lip 31 and the second lip 32 of the outer water cut to maintain a certain elasticity and facilitate the outer water cut to be fastened in the installation groove of the reinforcing plate 2.
[0042] like Figure 2 As shown, in the embodiment of the present application, a first mounting hole is provided on the strip body 30 of the outer water cut, and a second mounting hole corresponding to the first mounting hole is provided in the mounting groove, and the outer water cut fixing structure of the door includes a fastener, and the fastener passes through the first mounting hole and the second mounting hole to fix the outer water cut in the mounting groove of the reinforcing plate 2. The fastener is a bolt, and the bolt includes a screw rod 51 and a nut 52, and the first mounting hole and the second mounting hole are both through-hole structures.
[0043] More specifically, three first mounting holes are provided on the strip-shaped body 30 of the outer water cut along the length direction, and three second mounting holes are provided in the mounting groove of the reinforcing plate 2 along the length direction. When the outer water cut is placed horizontally in the mounting groove, the three first mounting holes correspond one to one with the three second mounting holes, and three groups of bolts are used. Each group of bolts includes a screw 51 and a nut 52. Each screw 51 passes through each first mounting hole and each second mounting hole respectively, and is then screwed and fastened with each nut 52 to fix the outer water cut in the mounting groove of the reinforcing plate 2.
[0044] It should be noted that those skilled in the art may also use screws, and both the first mounting hole and the second mounting hole are configured as threaded holes so that the external watertight part can be fixed in the mounting groove of the reinforcing plate 2 .
[0045] Embodiment 2
[0046] like Figure 1 and Figure 3 As shown, the horizontal edging structure 11 of the door outer panel 1 in the embodiment of the present application is constructed as a downwardly folded N-shaped structure, and the width of the edging structure 11 is 8 mm. The horizontal side edge of the reinforcing plate 2 is embedded in the inner side of the edging structure 11 in the horizontal direction, and the side edge of the reinforcing plate 2 is fastened to the door outer panel 1 by pressing the edging structure 11 of the door outer panel 1. The reinforcing plate 2 extends from the edging structure 11 to the inner side of the vehicle door to form a stepped installation groove capable of accommodating the outer water cut.
[0047] like Figure 3 As shown, in the embodiment of the present application, the outer water cut includes a horizontally placed strip body 30 and a first lip 31 and a second lip 32 formed on the upper side of the strip body 30 in sequence, and the outer water cut also includes a third lip 33 formed on the lower side of the strip body 30. Among them, the state of the outer water cut includes an unextruded state 32a and an extruded state 32b, and the second lip 32 remains separated from the first lip 31 in the unextruded state 32a. When the strip body 30 of the outer water cut is fixed in the mounting groove of the reinforcing plate 2, the lower side edge of the first lip 31 abuts against the horizontal outer side edge of the edging structure 11 of the door outer panel 1.
[0048] like Figure 3 As shown, in the embodiment of the present application, the cross-section of the first lip 31 of the outer water cut has a T-shaped structure, the head width of the T-shaped structure is 12 mm, one side of the T-shaped structure is against the outer side of the edging structure 11, and the end of the second lip 32 of the outer water cut and the end of the third lip 33 both have a barb structure.
[0049] It is understandable that the vehicle door includes a vehicle door glass. When the vehicle door is completely assembled, the outer water cut is fixed in the mounting groove on the reinforcing plate 2, and the second lip 32 and the third lip 33 of the outer water cut are tightly pressed against the outer surface of the vehicle door glass in horizontal upper and lower positions. Among them, after the second lip 32 of the outer water cut is squeezed by the vehicle door glass, the second lip 32 of the outer water cut undergoes elastic deformation in the squeeze state 32b so that the barb structure of the second lip 32 is pressed against the upper side of the T-shaped structure. That is, the first lip 31 of the outer water cut is clamped and squeezed and fixed between the edging structure 11 of the vehicle door panel and the second lip 32 of the outer water cut, and the head surface of the T-shaped structure is exposed to the outside and remains flush with the surface of the door outer panel 1.
[0050] It should be noted that when the user pays attention to the car door from the outside, most of the structure of the outer water cut is installed and hidden on the inner side of the reinforcing plate 2, and only the surface of the first lip edge 31 of the outer water cut is exposed on the side of the door outer panel 1. That is, the head surface of the T-shaped structure is exposed on the outside of the car door and is flush with the surface of the door outer panel 1, thereby greatly reducing the exposed area of the outer water cut on the door outer panel 1 and the user's attention, enhancing the hiding effect of the outer water cut and improving the user experience.
[0051] like Figure 3 As shown, one side of the first lip 31 of the outer water cut in the embodiment of the present application is sealed and connected to the edge structure 11. That is, the side below the head of the T-shaped structure and the outer end of the horizontal edge structure 11 of the door outer panel 1 are sealed with sealant.
[0052] It is understandable that when the glass encounters rain or the car is washed, the water flow on the door glass directly passes through the head surface of the first lip 31 and flows to the surface of the door outer panel 1, avoiding the water flow from the gap between the edging structure 11 of the door outer panel 1 and the first lip 31 of the outer water cut into the side of the reinforcing plate 2, thereby avoiding erosion damage to the door assembly and improving the waterproof sealing performance of the door.
[0053] like Figure 3 As shown, the external water cutter in the embodiment of the present application also includes a frame 4, which is embedded and fixed in the strip-shaped body 30, and the frame 4 is an inverted and inclined L-shaped structure.
[0054] like Figure 3 As shown, in the embodiment of the present application, a hook 41 is provided on the inner and outer water cutter, and a hole matching with the hook 41 is provided in the installation groove. The hook 41 is fixed on the frame 4.
[0055] More specifically, the frame 4 is provided with three hooks 41 along the length direction, and the mounting groove of the reinforcing plate 2 is provided with three holes along the length direction. When the strip body 30 of the outer water cut is horizontally placed in the mounting groove, the three hooks 41 are respectively engaged with the three holes to fix the outer water cut in the mounting groove of the reinforcing plate 2.
[0056] It should be noted that the width of the edging structure 11 and the head width of the T-shaped structure in the above-mentioned embodiment 1 and embodiment 2 are not restrictive. According to actual applications, technical personnel in this field can also select a suitable width of the edging structure 11 within the range of 6mm-8mm to ensure the firm connection between the door outer panel 1 and the reinforcing plate 2, and select a suitable head width of the T-shaped structure within the range of 4mm-12mm to minimize the exposed area of the external water cut.
[0057] In addition, the skeleton 4 in the above-mentioned embodiment 1 and embodiment 2 is made of steel bars or aluminum alloy bars. It can be understood that the outer water cut uses a rubber injection molding process to wrap the skeleton 4 in the outer water cut body. The skeleton 4 can support the first lip 31 and the second lip 32 of the outer water cut and facilitate fastening the outer water cut in the installation groove of the reinforcing plate 2.
[0058] Finally, the present application also provides a vehicle and a vehicle door, both of which include the above-mentioned external water-cut fixing structure of the vehicle door.
[0059] So far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present application.
