In addition, the terms "first" and "second" in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0023] See also Figure 1 to Figure 2The vehicle of the embodiment of the present application includes a vehicle body 1, a rear door 2 and a sealing assembly 3. The rear door 2 includes an upper door 21 and a lower door 22. The upper door 21 and the lower door 22 are rotatably connected to the vehicle body 1. The upper door 21 can be opened upward, and the lower door 22 can be opened downward, that is, the upper door 21 and the lower door 22 are opened opposite to each other to enrich the usage scenarios.

[0024] The sealing assembly 3 includes a first sealing member 31 fixed to the vehicle body 1 and a second sealing member 32 fixed to the sky door 21. After the sky door 21 and the ground door 22 are closed, the sky door 21 and the first sealing member 31 are sealed together, the second sealing member 32 and the first sealing member 31 are sealed together, the ground door 22 and the first sealing member 31 are sealed together, and the ground door 22 and the second sealing member 32 are sealed together, so as to prevent water leakage between the sky door 21 and the vehicle body 1, between the ground door 22 and the vehicle body 1, and between the sky door 21 and the ground door 22.

[0025] Ginseng Figure 3 , Figure 4 and Figure 5 The first sealing member 31 forms a closed ring shape, including a first fixing portion 310 , a first base portion 311 connected to the first fixing portion 310 , and a first lower sealing lip 312 and a second lower sealing lip 313 extending from the first base portion 311 .

[0026] The first fixing portion 310 is fixed to the vehicle body 1. In some embodiments, the first fixing portion 310 is detachably connected to the vehicle body 1 to facilitate replacement of the first sealing member 31. In other embodiments, the first fixing portion 310 is integrally provided with the vehicle body 1 and cannot be detached. For example, the first fixing portion 310 is injection molded on the vehicle body 1.

[0027] In some embodiments, the first base 311 is hollow to provide a deformation space for the first base 311 to improve the sealing effect.

[0028] Ginseng Figure 6 , Figure 7 and Figure 8 The second seal 32 includes a main seal 321 and a pair of corner seals 322 fixed to the main seal 321 .

[0029] When the sky door 21 and the ground door 22 are closed, a portion of the corner seal 322 is sealed against the first seal 31 , and another portion is sealed against the ground door 22 , and the main body seal 321 is sealed against the ground door 22 .

[0030] In some embodiments, the main body seal 321 is U-shaped, and a pair of corner seals 322 are located at opposite ends of the main body seal 321 .

[0031] In some embodiments, a pair of the corner seals 322 are symmetrically disposed at opposite ends of the main body seal 321 .

[0032] In some embodiments, the hardness of the corner seal 322 is greater than the hardness of the main body seal 321 to prevent excessive deformation when squeezed, thereby improving the sealing effect. In other embodiments, the hardness of the corner seal 322 may also be the same as or lower than the hardness of the main body seal 321.

[0033] In some embodiments, the corner seal 322 is injection molded with the main body seal 321. In other embodiments, the corner seal 322 is assembled and fixed with the main body seal 321, for example, by snapping, welding, or bonding.

[0034] The corner seal 322 includes a second base 3220 and a first upper sealing lip 3221, a second upper sealing lip 3222 and a third upper sealing lip 3223 extending from the second base 3220. After the skylight 21 is closed, the first upper sealing lip 3221 is sealed against the first lower sealing lip 312, the second upper sealing lip 3222 is sealed against the first base 311, and the third upper sealing lip 3223 is sealed against the second lower sealing lip 313, so as to form a first water guide channel 3224 and a second water guide channel 3225 on opposite sides of the second upper sealing lip 3222.

[0035] Even if a small amount of water passes through the sealing position of the first sealing member 31 and the second sealing member 32 and enters the first water guiding channel 3224 or the second water guiding channel 3225, it can be discharged smoothly to avoid water accumulation and entering the vehicle, so as to improve the sealing performance of the sealing assembly 3 and provide a better waterproof effect.

[0036] In some embodiments, the free end of the second base 3220 is in an outwardly convex arc shape.

[0037] Ginseng Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12The second base 3220 is provided with an outer side surface 3226 facing the outer side of the vehicle and an inner side surface 3227 opposite to the outer side surface 3226. The first upper sealing lip 3221 is close to the outer side surface 3226. At least part of the first water guide channel 3224 is located between the first upper sealing lip 3221 and the second upper sealing lip 3222, and the second water guide channel 3225 is located between the second upper sealing lip 3222 and the third upper sealing lip 3223. After the sky door 21 is closed, along the direction from top to bottom of the sky door 21, the first water guide channel 3224 gradually narrows, and the second water guide channel 3225 gradually widens.

[0038] The first water guiding channel 3224 is located on the outside of the second water guiding channel 3225. If water passes over the first upper sealing lip 3221 and enters the first water guiding channel 3224, the larger water inlet of the first water guiding channel 3224 can accommodate more water, so that the water can be smoothly discharged along the first water guiding channel 3224. Even if a small amount of water passes over the second upper sealing lip 3222, it can also be smoothly discharged along the gradually widening second water guiding channel 3225, resulting in better water guiding effect and better sealing effect.

[0039] In some embodiments, the third upper sealing lip 3223 includes a first sealing portion 32231 and a second sealing portion 32232 connected to the first sealing portion 32231. The first sealing portion 32231 extends along the length direction of the second base portion 3220 and is close to the inner side surface 3227, and the second sealing portion 32232 extends along the width direction of the second base portion 3220 to the outer side surface 3226 of the second base portion 3220.

[0040] In some embodiments, the second upper sealing lip 3222 includes a third sealing portion 32221 and a fourth sealing portion 32222 connected to the third sealing portion 32221. The third sealing portion 32221 extends along the length direction of the second base portion 3220, and the fourth sealing portion 32222 extends along the width direction of the second base portion 3220 to the outer side surface 3226 of the second base portion 3220.

[0041] In some embodiments, along the length direction X of the corner seal 322, the end of the first sealing portion 32231 and the end of the first upper sealing lip 3221 both exceed the end of the third sealing portion 32221, part of the first water guiding channel 3224 is located between the first sealing portion 32231 and the first upper sealing lip 3221, and another part of the first water guiding channel 3224 is located between the second upper sealing lip 3222 and the first upper sealing lip 3221.

[0042] In some embodiments, the end of the third sealing portion 32221 is connected to the first sealing portion 32231, and the first height of the end of the third sealing portion 32221 extending from the second base 3220 is lower than the second height of the first sealing portion 32231 extending from the second base 3220 and the third height of the first upper sealing lip 3221 extending from the second base 3220, so as to facilitate the gathering of water in the first water guiding channel 3224.

[0043] In some embodiments, on the outer side surface 3226, the end of the second sealing portion 32232 exceeds the end of the fourth sealing portion 32222, so as to maximize the water discharge to the outer side surface 3226 to improve the sealing effect.

[0044] In some embodiments, the first upper sealing lip 3221 is arranged outwardly obliquely relative to the second base 3220 in the direction toward the outer side surface 3226. The first upper sealing lip 3221 has a better water-blocking effect to improve the sealing effect. The first upper sealing lip 3221 is provided with an inner surface 32211 close to the first water-guiding channel 3224 and an outer surface 32212 arranged opposite to the inner surface 32211, and the outer surface 32212 forms a water-guiding surface. Water flows down along the water-guiding surface, and water is prevented from entering the first water-guiding channel 3224 as much as possible to improve the sealing effect.

[0045] In some embodiments, the third upper sealing lip 3223 is disposed obliquely outwardly relative to the second base 3220 in a direction toward the inner side surface 3227. The third upper sealing lip 3223 has a water-blocking function to improve the sealing effect.

[0046] When the sky door 21 and the ground door 22 are closed, the first upper sealing lip 3221 first suppresses the water impact outside the vehicle, which can play a great role in water blocking and water guiding; when the sealing of the first upper sealing lip 3221 fails, the water will be discharged out of the vehicle along the first water guiding channel 3224; when the water in the first water guiding channel 3224 passes over the second upper sealing lip 3222 and enters the second water guiding channel 3225, it will be discharged out of the vehicle along the second water guiding channel 3225.

[0047] The sealing component 3 has higher waterproofness, high water shock resistance, and faster water repellence and water conduction; at the same time, the first upper sealing lip 3221, the second upper sealing lip 3222 and the third upper sealing lip 3223 also play a role in clamping the first sealing component 31, forming a closed airtight space, which improves airtightness while being waterproof and minimizes airtight leakage; furthermore, the better sealing effect of the sealing component 3 enables it to accommodate more manufacturing deviations of the sky door 21 and the ground door 22, from the conventional plus or minus 2mm to plus or minus 4mm, which is beneficial to the processing and manufacturing of the sky door 21 and the ground door 22.

[0048] Ginseng Fig.12 , Fig.13 , Fig.14 , Fig.15 and Fig.16 In some embodiments, after the sky door 21 and the ground door 22 are closed, along the height direction of the sky door 21, the vehicle includes a first sealing position, a second sealing position, a third sealing position, a fourth sealing position and a fifth sealing position which are sequentially arranged.
