DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] Before further describing the implementation methods of the present application in detail, the directional nouns involved in the embodiments of the present application are based on the directions shown in the figures and are only used to clearly describe the sealing structure of the four doors of a vehicle in the embodiments of the present application, and do not have the meaning of limiting the scope of protection of the present application.

[0033] The X, Y, and Z axes in the present invention represent the assembly direction of the inner water cut on the vehicle, that is, they represent the up and down (vertical), left and right, front and back positions. The X axis represents the left and right direction of the inner water cut, and the arrow direction of the X axis is the positive direction of the view. Taking the vehicle body as an example, it refers to the rear side of the tail, and vice versa, it is the opposite direction, which refers to the front side of the vehicle body; the Y axis represents the front and rear direction of the inner water cut, and the arrow direction of the Y axis is the positive direction of the view. Taking the vehicle body as an example, it refers to the outer side of the vehicle, and vice versa, it is the opposite direction, which refers to the inner side of the vehicle body; the Z axis represents the up and down (vertical) direction of the inner water cut, and the arrow direction of the Z axis is the positive direction of the view. Taking the vehicle body as an example, it refers to the upper side of the vehicle, and vice versa, it is the opposite direction, which refers to the lower side of the vehicle body; at the same time, it should be noted that the aforementioned X axis, Y axis, and Z 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 to the present invention.

[0034] In the description of the present invention, the terms "first", "second", "third", etc. in the specification and claims and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein.

[0035] With the rapid development of the new energy vehicle industry, the requirements for the appearance of automobiles are becoming younger and younger. The novel frameless door structure has become the direction in which many car companies have focused their efforts. As important sealing accessories on the door, the installation accuracy of the inner water cut and the triangular window sealing strip greatly affects the appearance quality and sealing performance of the whole vehicle. How to reduce the assembly burden and working hours of workers and quickly identify problems such as wrong installation and inadequate assembly are still areas that major OEMs urgently need to improve.

[0036] The traditional way of assembling sealing strips on door stoppers often adopts an n-type plug-in installation structure. It can be understood that one end of the inner water cut (B-pillar / C-pillar end) is used as a positioning reference, and inserted along the B-pillar / C-pillar end of the sheet metal stop, and then the sheet metal stop is gradually pressed into the inner water cut groove at the other end. This installation structure is simple in design and easy to operate, but the positioning of the end depends entirely on the operator's vision and feel. There are often problems such as excessive gaps at the matching points of the end heads and incomplete installation, resulting in obvious gaps and uneven straight sections in the matching of the window frame with the car frame. In severe cases, it causes rain leakage and excessive wind noise.

[0037] Although some existing improved installation structures have added the positioning function, they are all aimed at limiting the movement of the inner water cut on the stop to solve the problem of lack of positioning in the assembly. However, the complex design of this structure significantly increases the assembly time, and still does not help the operator to solve the problem of how to quickly locate and identify whether the assembly is in place.

[0038] In order to solve the problem that the prior art assembly lacks obvious positioning structure and the function of quickly identifying problems, an embodiment of the present application provides a sealing structure for four doors of a vehicle and a vehicle; the structure is applied to the installation of an inner water cut, but is not limited to the installation of an inner water cut.

[0039] The embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0040] Combination Figure 1-Figure 6 As shown, a sealing structure of four doors of a vehicle provided by an embodiment of the present application comprises a front door inner water cut 2, a rear door inner water cut 3, a front door inner panel 4 and a rear door inner panel 5; both the front door inner panel 4 and the rear door inner panel 5 are provided with a limiting groove; the upper ends of the front door inner panel 4 and the rear door inner panel 5 are both stop edges; the front door inner water cut 2 is connected to the front door inner panel 4; the rear door inner water cut 3 is connected to the rear door inner panel 5;

[0042] The overlap portion 11 is provided at the place where the stop edge 31 of the front door inner panel cooperates with the triangular window sealing strip 1; a space for accommodating the inner water-cut straight section of the front door is provided between the overlap portion 11 and the stop edge 31 of the front door inner panel;

[0043] A groove is arranged on the stop edge of each door inner panel; a positioning boss is arranged on the front door inner water cut 2 and the rear door inner water cut 3; and the positioning boss is matched and connected with the corresponding groove.

[0044] In addition, in this embodiment, marking lines are provided on the front door inner panel 4 and the rear door inner panel 5, and the marking lines are used to indicate whether the front door inner water cut 2 and the rear door inner water cut 3 are installed in place in the horizontal and vertical directions.

[0045] By arranging an overlap portion at the joint position between the stop edge of the front door inner panel and the triangular window sealing strip, a space for accommodating the hand-cut straight section of the front door inner is arranged between the overlap portion and the stop edge of the front door inner panel; thereby, sufficient space can be provided for the installation of the inner water cut of the front door, solving the problem that the inner water cut of the front door cannot be installed in place due to insufficient installation space; by arranging an angle portion on the inner water cut, and arranging a limiting groove on the door inner panel, the cooperation of the angle portion and the limiting groove limits the lateral position of the inner water cut; by arranging a positioning boss on the inner water cut, and arranging a groove on the stop edge of the door inner panel; the cooperation of the positioning boss and the groove enables the operator to quickly identify the installation position of the inner water cut, and by cooperating with the angle portion and the limiting groove, the inner water cut is further positioned laterally; thereby, the installation accuracy of the inner water cut is ensured.

[0046] In the embodiment of the present application, marking lines are also provided on the front door inner panel 4 and the rear door inner panel 5, and the marking lines are used to indicate whether the front door inner water cut 2 and the rear door inner water cut 3 are installed in place in the horizontal and vertical directions. By providing various marking lines to indicate whether the inner water cut is installed in place in the vertical and horizontal directions, the installation quality and the size of each inner water cut are matched with the door inner panel can be judged, so as to improve the installation quality of the inner water cut and avoid problems such as wrong installation, missing installation and inadequate assembly.

[0047] The marking line includes a first scale line 101, and the first scale line 101 includes a first transverse line and a first longitudinal line; the first transverse line is used to indicate whether the longitudinal straight section of the front door inner water cut 2 is installed in place;

[0048] The first longitudinal line is used to indicate whether the straight section of the front door inner water cut 2 is installed in place horizontally.

[0049] The marking lines also include scale lines at the corners and corner edges; the corner edges are set at the intersection of the corner portion and the straight portion; the scale lines at the corners are set on the inner panels of each door, and the scale lines at the corners include transverse lines at the corners and longitudinal lines at the corners; the transverse lines at the corners are used to indicate whether the corner portion of the inner water cut is installed in place longitudinally; the longitudinal lines at the corners are used to align with the corner edges to indicate that the corner portion is installed in place transversely.

[0050] The transverse width of the longitudinal line at the corner is a set width; the longitudinal line at the corner is also used to indicate whether the positioning boss is inserted into the corresponding groove.

[0051] Indicator arrows are also provided on the front door inner water cut 2 and the rear door inner water cut 3 respectively; the indicator arrows indicate the installation direction of the front door inner water cut 2 and the rear door inner water cut 3.

[0052] Combine the following Figure 1-Figure 6 The various components and functions of the structure provided in this embodiment are described in more detail.

[0053] like Figure 1As shown, before the front door inner water cut 2 and the rear door inner water cut 3 are assembled, the triangular sealing strip 1 is already in a state of being assembled with the front door inner water cut 2. The front door inner water cut 2 and the rear door inner water cut 3 are installed with the B-pillar end as the positioning reference. Taking the assembly operation of the front door inner water cut 2 as an example, the first corner portion 12 of the front door inner water cut 2 is pressed down, and then pressed down along the front door straight section 16 toward the front side of the vehicle body to complete the assembly.

[0054] like Figure 2 As shown, the triangular window sealing strip 1 is assembled on the guide rail along the Z direction to cooperate with the front door inner panel 4, and the guide rail is wrapped to present Figure 2 The state shown; an overlap portion 11 is provided at the matching position of the triangular window sealing strip 1 and the stop edge 31 of the front door inner panel, and the overlap portion 11 is a bent component, and the bent overlap portion is inverted on the stop edge 31 of the front door inner panel, and the Z-direction flange of the overlap portion 11 is higher than the upper end of the stop edge 31 of the front door inner panel, and a space for accommodating the inner water-cut straight section of the front door is provided between the overlap portion 11 and the upper end of the stop edge 31 of the front door inner panel, and the space height here can be 2.5mm, and the overlap portion 11 A positioning edge 21 is arranged on the top, and the positioning edge 21 is arranged horizontally and is flush with the stop edge 31 of the front door inner panel; when the positioning edge 21 is flush with the stop edge 31 of the front door inner panel, it indicates that the overlap portion 11 is installed in place; thereby preventing the space between the overlap portion 11 and the stop edge 31 of the front door inner panel from being too small, resulting in over-pressure assembly of the overlap portion 11, resulting in loss of matching space with the front door inner water cut 2, making the front door inner water cut 2 difficult to assemble during the subsequent installation process.

[0055] like Figure 3 As shown, the front door inner water cut 2 includes a first corner portion 12 and a front door straight section 16 connected to each other; the front door straight section 16 is installed on the stop edge 31 of the front door inner panel; a first limiting groove is provided at one end of the front door inner panel 4 close to the B-pillar, and the first corner portion 12 is installed in the first limiting groove.

[0056] The first scale line 101 is set on the stop edge 31 of the front door inner plate, the first limit groove can be a first U-shaped groove 33, the front door inner water cut 2 uses the first U-shaped groove 33 at the B-pillar end as the matching surface, and the first corner portion 12 is vertically inserted into the first U-shaped groove 33 downward, combined with Figure 2As shown, the front door inner water cut 2 includes a front door straight section 16 and a first corner section 12, the first corner section 12 is arranged at the end of the front door B-pillar, the first corner section 12 is connected to the front door straight section 16, the front door straight section 16 extends along the stop edge 31 of the front door inner panel to the front side of the vehicle body, to 3mm away from the overlapping portion, which is the standard assembly position; the first scale line 101 is set at a position of 6mm in the X-direction gap from the overlapping portion 11; the gap setting is the first indicator for detecting the length quality of components and the appearance quality of the product, and the 6mm gap is determined by accumulating the comprehensive tolerance (including the length tolerance and assembly tolerance of the front door water cut) at the A-pillar position after the B-pillar is positioned. When the front door inner water cut 2 is assembled, the lower edge of the front door straight section 16 should cover the first scale line 101. A horizontal line, that is, it covers the first scale line 101 in the Z direction, indicating that the longitudinal installation of the front door straight section 16 is in place; otherwise, it is considered that it is not pressed in place and needs to be pressed again until the front door straight section 16 covers the first scale line 101 in the Z direction; the second detection function of the first scale line 101 is to determine whether the length of the front door inner water cut 2 is out of tolerance. The identification method is that after the installation is completed, visually check whether the front end of the front door straight section 16 covers the first vertical line of the first scale line 101, that is, when it covers the first scale line 101 in the X direction, it indicates that the front door straight section 16 is installed in place horizontally; otherwise, it is considered that it is not assembled in place or the length of the front door incision is unqualified, and it needs to be pressed again. If the first scale line 101 can still be visually seen after absorbing the tolerance in the Z direction, the front door needs to be re-incision.

[0057] A first groove 39 is provided on the stop edge of the inner edge of the front door, a positioning boss 105 is provided on the inner water cut 2 of the front door, the intersection of the first corner portion 12 and the straight section 16 of the front door is the first corner edge 22, the first corner portion 12 is an injection molded part, and the straight section is an extruded part, and the first corner edge 22 at the intersection of the two can be used as the external positioning line of the inner water cut of the front door; the scale line at the corner aligned with the first corner edge 22 is the second scale line 102; a first indicator arrow 25 is provided on the inner water cut 2 of the front door, and the first indicator arrow 25 is vertically downwardly arranged along the Z direction on the protrusion of the first corner portion 12, facing the interior of the vehicle, and it points to the first groove 39, and the local cross-sectional view at the first indicator arrow 25 is as shown in FIG. Figure 6As shown, a positioning boss 105 is provided on the inner side of the first corner portion 12. It can be foreseen that during assembly, the first corner portion 12 is installed downward along the direction of the first indication arrow 25, and the positioning boss 105 is inserted into the first U-shaped groove 33. The Z-direction alignment of the first corner edge 22 and the second scale line 102 can also be combined to assist the installation. Because the first corner edge 22 and the second scale line 102 are aligned in the Z direction, when the operation is completed, it is possible to identify whether the positioning boss 105 is inserted into the first U-shaped groove 33 by a self-checking method. Since the matching tolerance between the first U-shaped groove 33 and the positioning boss 105 is 2 mm, the second scale line 102 is set. 2 is 2mm wide. When the inner water cut of the front door is assembled, the Z direction of the first corner edge 22 coincides with the longitudinal line of the second scale line 102 at the corner, that is, the first corner edge 22 does not exceed the width range of the longitudinal line of the second scale line 102 at the corner in the X direction. It can be regarded that the first corner part of the inner water cut of the front door is horizontally assembled in place, and the lower edge of the first corner edge 23 covers the transverse line of the corner of the second scale line 102, indicating that the longitudinal installation of the first corner part is in place. Otherwise, it is regarded as improper assembly and needs to be reassembled. Since this is the positioning reference, the quality of the corner installation at the B-pillar end greatly affects the installation of the entire inner water cut.

[0058] like Figure 3-Figure 5 As shown, the rear door inner water cut includes a second corner portion 13, a third corner portion 14 and a rear door straight section 17; the second corner portion 13 and the third corner portion 14 are arranged at both ends of the rear door straight section 17; the rear door straight section 17 is installed on the stop edge 32 of the rear door inner panel; a second limiting groove is arranged at one end of the rear door inner panel 5 close to the B-pillar; a third limiting groove is arranged at one end of the rear door inner panel close to the C-pillar; the second corner portion 13 and the third corner portion 14 are correspondingly installed in the second limiting groove and the third limiting groove.

[0059] The second limiting groove adopts the second U-shaped groove 34; the third limiting groove adopts the third U-shaped groove 35. The connection between the second corner portion 13 and the rear door straight section 17 is the second corner edge 23; the connection between the third corner portion 14 and the rear door straight section 17 is the third corner edge 24. The corner scale line used to align with the second corner edge 23 is the third scale line 103, and the corner scale line used to align with the third corner edge 24 is the fourth scale line 104; the third scale line 103 and the fourth scale line 104 are both set on the edge of the stopper of the rear door inner panel.

[0060] A second groove 40 is arranged on the stop edge 32 of the rear door inner panel, and a positioning boss 105 is arranged on the straight section 17 of the rear door; the second corner portion 13 is engraved with a second indicator arrow 26 facing the inner side of the vehicle, which points to the second groove 40 arranged on the stop edge 32 of the rear door inner panel in the same Z direction, and a third scale line 103 is arranged on the right side of the second groove 40 and is vertically aligned with the second corner edge 23, so that the second corner edge 23, the second indicator arrow 26, the second groove 40 and the third scale line 103 constitute a positioning mechanism for the rear door B-pillar.

[0061] The stop edge 32 of the rear door inner panel at the C-pillar end is provided with a fourth scale line 104, the fourth scale line 104 and the third corner edge 24 are in the same YZ plane, and the fourth scale line 104 and the third scale line 103 together form a detection mechanism at the rear door end.

[0062] When installing the rear door inner water cut 3, press the second corner portion 13 downward in the direction of the second indicator arrow 26 to install it, and insert the positioning boss 105 on the rear door inner water cut 3 into the second U-shaped groove 34. The installation can also be assisted by combining the Z-direction alignment of the longitudinal lines at the corner of the second corner edge 23 and the third scale line 102. When the lower edge of the second corner edge 23 covers the transverse line at the corner of the third scale line 103, it indicates that the longitudinal installation of the second corner portion 13 is in place; when the longitudinal lines at the corner of the second corner edge 23 and the third scale line 103 are aligned in the Z direction, it indicates that the transverse installation of the second corner portion 13 is in place. Therefore, when the operation is completed, the self-check method can be used to identify whether the positioning boss 105 is in the groove, such as Figure 6 As shown in , the specific method of judging the assembly quality needs to be explained in combination with the C-pillar end. When the lower edge of the third corner edge 24 covers the transverse line at the corner of the fourth scale line 104, it indicates that the third corner portion 13 is installed in place in the longitudinal direction; when the third corner edge 24 and the longitudinal line at the corner of the fourth scale line 104 are aligned in the Z direction, it indicates that the third corner portion 14 is installed in place in the transverse direction.

[0063] The transverse width of the corner longitudinal lines of the third scale line 103 and the fourth scale line 104 is 2 mm, which is determined according to the processing error and assembly error of the water cut inside the rear door.

[0064] After the second corner portion 13 is installed, visually check whether the second corner edge 23 and the lower edge of the second corner edge 23 are within the width range of the third scale line 103 (vertical line and horizontal line). If the second corner edge 23 and its lower edge are not within the width range of the third scale line 103, the assembly needs to be readjusted. After the second corner portion 13 and the third corner portion 14 are installed, visually check whether the third corner edge 24 is between the widths of the fourth scale line 104. Specifically, with respect to the assembly of the second corner portion 13, if the complete vertical scale line can be visually seen on any side, it is considered as an unqualified assembly and needs to be re-assembled. If the second corner portion 13 is in a qualified assembly state and the third corner edge 24 is seriously out of tolerance, it is considered as the rear door waterproofing is unqualified.
