[0035] At present, vehicles have been widely popularized in ordinary families and integrated into people's daily lives, and people use vehicles for travel more and more frequently. The back door is a structure on the vehicle used to cover the vehicle trunk, also known as the trunk cover.

[0036] In the related art, a sealing structure is provided at the rear portion of the body side, and the sealing structure is used to seal a gap between the back door and the back door opening of the body side after the back door of the vehicle is closed.

[0037] Specifically, the sealing structure usually includes a side inner panel, a side outer panel, a water flow channel and a sealing strip. One side of the water flow channel is connected to the side inner panel and the other side is connected to the side outer panel. The sealing strip is installed on the side inner panel and the water flow channel. However, when the water flow in the water flow channel is too large, the water will flood the connection between the water flow channel and the side inner panel, so that the connection between the two is prone to rust due to being in a humid environment. In this way, the reliability and stability of the connection between the water flow channel and the side panel of the vehicle body will drop sharply.

[0038] Based on the above problems, the embodiments of the present application propose a tailgate sealing structure, a vehicle body and a vehicle, aiming to solve the problem of easy rust at the connection position between the water flow channel and the side inner panel, thereby helping to improve the reliability of the connection between the side inner panel and the water flow channel.

[0039] In a first aspect, the present application provides a back door sealing structure 100. Figures 1 to 5 As shown, the back door sealing structure 100 includes a side inner panel 110, a side water channel 120 and a sealing strip 130. The side water channel 120 is located on the outer side of the side inner panel 110, and includes a water channel body 121, a first flange 123 and a connecting plate 122. The first flange 123 is arranged on a side of the water channel body 121 close to the side inner panel 110, and the connecting plate 122 is connected to the first flange 123, and the connecting plate 122 is also connected to the side inner panel 110. The sealing strip 130 includes a mounting base 131 and a first lip 132 arranged on one side of the mounting base 131. The mounting base 131 is covered on the outside of the connecting plate 122 and the side inner panel 110, and the first lip 132 abuts against the first flange 123.

[0040] The back door sealing structure 100 of the present application includes a side inner panel 110, a side water flow channel 120 and a sealing strip 130. It can be understood that the back door sealing structure 100 is applicable to a vehicle 1 with a back door 12. Figure 1 and Figure 4 As shown, a back door opening 11 is provided at the rear of the vehicle body 10, and a back door 12 is provided at the back door opening 11 in a switchable manner. The rear part of the vehicle body roof and the rear part of the side wall of the vehicle body 10 respectively constitute the upper side and the side side of the back door opening 11.

[0041] The side inner panel 110 is an inner structural member of the side of the vehicle body 10, and is used to improve the strength of the vehicle body. The inner side refers to the side close to the interior space of the vehicle. The side water trough 120 includes a water trough body 121, a first flange 123, and a connecting plate 122. The water trough body 121 is used to drain water. The first flange 123 is arranged between the connecting plate 122 and the water trough body 121. By setting the first flange 123, it is beneficial to improve the convenience of manufacturing the connecting plate 122. The connecting plate 122 is connected to the side inner panel 110. For example, the two can be fixedly connected by welding, screw connection, riveting, etc. In this way, the side water trough 120 can timely guide the water that falls on the vehicle body 10 to prevent moisture from entering the interior of the vehicle, thereby helping to improve the drainage performance of the vehicle body 10.

[0042] like Figure 3 , Figure 6 As shown, the sealing strip 130 includes a mounting base 131 and a first lip 132. The mounting base 131 refers to a structure of the sealing strip 130 for mounting with an external component, and the first lip 132 refers to a structure of the sealing strip 130 for sealing with an external component.

[0043] In the back door sealing structure 100 of the present application, the first lip 132 of the sealing strip 130 is in contact with the first flange 123. The first lip 132 can form a sealing barrier between the water trough body 121 and the side inner panel 110. When there is a lot of water in the water trough body 121, the first lip 132 can prevent the water from passing through the water trough body 121 and entering the mounting base 131. In this way, the connection position between the connecting plate 122 inside the mounting base 131 and the side inner panel 110 is always in a dry environment, which is conducive to reducing the probability of rust at the connection position between the connecting plate 122 and the side inner panel 110, and further helps to improve the reliability of the connection between the side inner panel 110 and the side water trough 120.

[0044] In addition, the side water channel 120 is a secondary visible area. When the back door 12 is opened, the first lip 132 of the sealing strip 130 abuts against the first flange 123, and the mounting base 131 is also covered on the outside of the connecting plate 122 and the side inner plate 110, so that the connection part of the connecting plate 122 and the side inner plate 110 is not exposed to the outside, which is also conducive to improving the aesthetics of the back door sealing structure 100, and further helps to improve the appearance quality of the whole vehicle.

[0045] In some embodiments, Figure 3 and Figure 6 As shown, the sealing strip 130 further includes a sealing bubble tube 133, which is disposed on a side of the mounting base 131 away from the side inner panel 110. When the back door 12 is closed, the sealing bubble tube 133 is compressed by the back door 12, so that the back door 12 and the back door opening 11 of the vehicle body 10 can be sealed.

[0046] In some embodiments, Figure 3 and Figure 6 As shown, the sealing strip 130 also includes a second lip 134 disposed on one side of the mounting base 131, the second lip 134 is spaced apart from the first lip 132, the second lip 134 is located on the side of the first lip 132 close to the connecting plate 122, and the second lip 134 abuts against the first flange 123. In this way, the first lip 132 can form a first seal, and the second lip 134 can form a second seal. The two seals are used to prevent water from passing over the water channel body 121 and entering the mounting base 131. In this way, the probability of rusting at the connection position between the connecting plate 122 and the side inner plate 110 is further reduced, and the reliability of the connection between the side inner plate 110 and the side water channel 120 is further improved.

[0047] In some embodiments, Figure 3 and Figure 6 As shown, a slot 1311 is provided at the bottom of the mounting base 131, and at least part of the connecting plate 122 and the side inner plate 110 are located in the slot 1311. The slot 1311 includes a first side wall 1311a and a second side wall 1311b that are arranged opposite to each other, and a plurality of third lips 1312 are arranged at intervals on the first side wall 1311a and the second side wall 1311b, and the third lips 1312 located on the first side wall 1311a abut against the connecting plate 122, and the third lips 1312 located on the second side wall 1311b abut against the side inner plate 110. In this way, the mounting base 131, the connecting plate 122, and the side inner plate 110 can be installed and fixed. At the same time, the third lip edge 1312 can also increase the contact area between the sealing strip 130 and the connecting plate 122 and between the sealing strip 130 and the side inner panel 110, thereby helping to improve the installation strength of the sealing strip 130 and prevent it from falling off the connecting plate 122 and the side inner panel 110.

[0048] In some embodiments, Figures 2 to 5 As shown, the back door sealing structure 100 further includes a side outer panel 140, and the side water channel 120 further includes a second flange 124, and the second flange 124 and the first flange 123 are arranged on opposite sides of the water channel body 121. The side outer panel 140 is connected to the second flange 124, for example, by welding, screw connection, riveting, etc. In this way, the side water channel 120 can be fixedly installed with the side inner panel 110 and the side outer panel 140, so as to improve the convenience of connecting the side water channel 120.

[0049] In some embodiments, Figure 4 and Figure 5As shown, a lock mounting hole 1241 is provided at the rear end of the second flange 124. A lock head or a lock block can be installed in the lock mounting hole 1241, and a lock block and a lock head can be installed on the back door 12 accordingly. When the back door 12 is closed, the back door 12 and the back door sealing structure 100 can be locked. In addition, the lock mounting hole 1241 is located at the rear end of the second flange 124, that is, at the tail end of the second flange 124. In this way, the position of the lock head or the lock block is close to the tail end of the vehicle body 10, which is conducive to improving the locking stability of the back door and the back door sealing structure 100.

[0050] In some embodiments, Figure 3 As shown, the water trough body 121 includes a bottom plate 1211, a first side plate 1212 and a second side plate 1213. The first side plate 1212 and the second side plate 1213 are arranged opposite to each other and are both connected to the bottom plate 1211. The first side plate 1212 is located on the side of the second side plate 1213 close to the connecting plate 122. In this way, the water trough body 121 is in a groove shape, so that on the one hand, a space for accommodating water flow is formed, and on the other hand, the water flow can be guided, which is conducive to improving the drainage performance of the side water trough 120.

[0051] In some embodiments, Figures 1 to 3 As shown, in any cross section perpendicular to the second direction, the top of the second side plate 1213 is lower than the top of the first side plate 1212, and the second direction is the front-rear direction of the vehicle. Since the first side plate 1212 is closer to the side inner plate 110 than the second side plate 1213, and the top of the second side plate 1213 is set to be lower than the top of the first side plate 1212, it is helpful to further reduce the probability of the water flow in the water trough body 121 entering the inside of the mounting base 131, so that the connection position of the connecting plate 122 inside the mounting base 131 and the side inner plate 110 is always in a dry environment, which is helpful to reduce the probability of rust at the connection position of the connecting plate 122 and the side inner plate 110, and further help to improve the reliability of the connection between the side inner plate 110 and the side water trough 120.

[0052] In some embodiments, Figure 3 As shown, a first angle α is formed between the first side plate 1212 and the bottom plate 1211, and a second angle β is formed between the second side plate 1213 and the bottom plate 1211, and both the first angle α and the second angle β are greater than 90°. This arrangement allows the groove shape of the water trough body 121 to present an outward-expanding structure from the bottom to the upper opening. On the one hand, the cross-sectional area of ​​the groove shape can be expanded within a limited space, thereby enhancing the ability of the water trough body 121 to guide water flow. On the other hand, it is also possible to prevent the formation of dead corners that are difficult to clean in the water trough body 121, thereby helping to reduce the difficulty of cleaning the water trough body 121.

[0053] In a second aspect, the present application provides a vehicle body 10. Figure 1 and Figure 2 Shown and referenced Figure 4 The vehicle body 10 includes the tailgate sealing structure 100 described in the first aspect, a tailgate opening 11 is provided at the rear of the vehicle body 10, a sealing strip 130 is provided around the tailgate opening 11, and there are two side water flow grooves 120 located on both sides of the tailgate opening 11 in a first direction, where the first direction is the left and right direction of the vehicle.

[0054] The vehicle body 10 of the present application uses the back door sealing structure 100 described in the first aspect. Among them, the sealing strip 130 is arranged around the back door opening 11, and there are two side water troughs 120 and they are located on both sides of the back door opening 11 in the first direction. In addition, the side water trough 120 is connected to the side inner panel 110 through the connecting plate 122, and the mounting base 131 of the sealing strip 130 is coated on the outside of the connecting plate 122 and the side inner panel 110, and the first lip 132 is in contact with the first flange 123 of the side water trough 120. In this way, the first lip 132 can form a sealing barrier between the water trough body 121 and the side inner panel 110. When there is more water in the water trough body 121, the first lip 132 can prevent the water from passing through the water trough body 121 and entering the mounting base 131. In this way, the connection position of the connecting plate 122 and the side inner panel 110 inside the mounting base 131 is always in a dry environment, which is conducive to reducing the probability of rust at the connection position of the connecting plate 122 and the side inner panel 110, and further helps to improve the reliability of the connection between the side inner panel 110 and the side water flow groove 120. In addition, the side water flow groove 120 is a secondary visible area. When the back door is opened, the first lip edge 132 of the sealing strip 130 abuts against the first flange 123. At the same time, the mounting base 131 is also covered on the outside of the connecting plate 122 and the side inner panel 110, so that the connection position of the connecting plate 122 and the side inner panel 110 will not be exposed to the outside, which is also conducive to improving the aesthetics of the back door sealing structure 100, and further helps to improve the appearance quality of the vehicle body 10.

[0055] In a third aspect, the present application provides a vehicle 1. Figure 4 Shown and referenced Figure 2 The vehicle 1 includes a back door 12 and the vehicle body 10 described in the second aspect, and the back door 12 is movably connected to the vehicle body 10. The back door 12 includes a door top cover 12a, a door side panel 12b, and a door tail plate 12c. The door side panel 12b is connected to an end of the door top cover 12a along a first direction, and the door tail plate 12c is connected to an end of the door top cover 12a along a second direction. When the back door 12 is closed with the back door opening 11, the bottom and front of the door side panel 12b are butted against the back door sealing structure 100.

[0056] The vehicle 1 of the present application has a body 10 including a back door sealing structure 100. The first lip 132 of the sealing strip 130 of the back door sealing structure 100 can prevent water from passing over the water channel body 121 and entering the mounting base 131. In this way, the connection position of the connecting plate 122 and the side inner plate 110 inside the mounting base 131 is always in a dry environment, which is conducive to reducing the probability of rust at the connection position of the connecting plate 122 and the side inner plate 110, and further conducive to improving the reliability of the connection between the side inner plate 110 and the side water channel 120.

[0057] In addition, the side water flow channel 120 is a secondary visible area. When the tailgate 12 is opened, the first lip 132 of the sealing strip 130 abuts against the first flange 123. At the same time, the mounting base 131 is also covered on the outside of the connecting plate 122 and the side inner panel 110, so that the connecting part between the connecting plate 122 and the side inner panel 110 will not be exposed to the outside, which is beneficial to improve the aesthetics of the tailgate sealing structure 100, and further helps to improve the appearance quality of the vehicle 1.

[0058] In the third aspect, the structure of the back door 12 in the present application is different from that of the back door in the related art. Specifically, the back door 12 in the present application has a door top cover 12a connected to the door tail plate 12c and door side panels 12b located on both sides of the door top cover 12a in addition to the door tail plate 12c at the rear. In other words, the present application also incorporates a part of the structure of the body side panel, such as the D-pillar, the part between the D-pillar and the C-pillar, etc., into the back door 12. In this way, the back door opening 11 of the body 10 is larger. When the back door 12 is opened, the volume of the trunk space at the rear of the vehicle and the size in the second direction are larger, which is conducive to improving the application scenarios of the trunk at the rear of the vehicle and the back door 12, and reducing the difficulty of loading and unloading items. For example, the trunk and the back door 12 can be used as a commodity display rack. When the back door 12 is in the open state, the commodities for display can be placed in the trunk and hung on the inner side of the door top cover 12a and / or the door side panel 12b.
