Detailed implementation manners

[0040] Here, the technical solutions in the embodiments (or "implementation manners") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description involves the accompanying drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements.

[0041] If there are terms related to directional indication or positional relationship in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture (as shown in the drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0042] See Figures 1 to 2 , the vehicle according to the embodiment of the present application includes a vehicle body 1, a back door 2 and a sealing assembly 3. The back door 2 includes a top door 21 and a bottom door 22. The top door 21 and the bottom door 22 are rotatably connected to the vehicle body 1. The top door 21 can be opened upward, and the bottom door 22 can be opened downward, that is, the top door 21 and the bottom door 22 are opened oppositely to enrich the usage scenarios.

[0043] The sealing assembly 3 includes a first seal 31 fixed to the vehicle body 1 and a second seal 32 fixed to the top door 21. After the top door 21 and the bottom door 22 are closed, the top door 21 is sealed in contact with the first seal 31, the second seal 32 is sealed in contact with the first seal 31, the bottom door 22 is sealed in contact with the first seal 31, and the bottom door 22 is sealed in contact with the second seal 32 to prevent water leakage between the top door 21 and the vehicle body 1, between the bottom door 22 and the vehicle body 1, and between the top door 21 and the bottom door 22.

[0044] See Figure 3 , Figure 4 and Figure 5 , the first seal 31 forms a closed ring, 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.

[0045] 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 the replacement of the first seal 31. In other embodiments, the first fixing portion 310 is integrally provided with the vehicle body 1 and is not detachable. For example, the first fixing portion 310 is injection molded on the vehicle body 1.

[0046] In some embodiments, the first base portion 311 is hollow to provide a deformation space for the first base portion 311 to improve the sealing effect.

[0047] Reference 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.

[0048] After the upper door 21 and the lower door 22 are closed, a part of the corner seal 322 is sealed in contact with the first seal 31, another part is sealed in contact with the lower door 22, and the main seal 321 is sealed in contact with the lower door 22.

[0049] In some embodiments, the main seal 321 is U-shaped, and a pair of the corner seals 322 are located at opposite ends of the main seal 321.

[0050] In some embodiments, a pair of the corner seals 322 are symmetrically arranged at opposite ends of the main seal 321.

[0051] In some embodiments, the hardness of the corner seal 322 is greater than that of the main seal 321 to prevent excessive deformation when being squeezed and improve the sealing effect. In other embodiments, the hardness of the corner seal 322 may also be the same as or lower than that of the main seal 321.

[0052] In some embodiments, the corner seal 322 and the main seal 321 are injection molded. In other embodiments, the corner seal 322 and the main seal 321 are assembled and fixed. For example, they can be fixed by means of snap-fastening, welding, bonding, etc.

[0053] 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 upper door 21 is closed, the first upper sealing lip 3221 is sealed in contact with the first lower sealing lip 312, the second upper sealing lip 3222 is sealed in contact with the first base 311, and the third upper sealing lip 3223 is sealed in contact with the second lower sealing lip 313 to form a first water guiding channel 3224 and a second water guiding channel 3225 on opposite sides of the second upper sealing lip 3222.

[0054] 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.

[0055] In some embodiments, the free end of the second base 3220 is in an outwardly convex arc shape.

[0056] Ginseng Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 The 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] In some embodiments, along the length direction X of the corner sealing member 322, the end portions of the first sealing portion 32231 and the first upper sealing lip 3221 both extend beyond the end portion 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.

[0061] In some embodiments, the end portion of the third sealing portion 32221 is connected to the first sealing portion 32231. The first height at which the end portion of the third sealing portion 32221 extends from the second base portion 3220 is lower than the second height at which the first sealing portion 32231 extends from the second base portion 3220 and the third height at which the first upper sealing lip 3221 extends from the second base portion 3220, facilitating the convergence of water within the first water guiding channel 3224.

[0062] In some embodiments, on the outer side surface 3226, the end portion of the second sealing portion 32232 extends beyond the end portion of the fourth sealing portion 32222, maximizing the drainage of water to the outer side surface 3226 to improve the sealing effect.

[0063] In some embodiments, the first upper sealing lip 3221 is obliquely arranged outward relative to the second base portion 3220 in the direction towards 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. The outer surface 32212 forms a water guiding surface. Water flows down along the water guiding surface, minimizing the entry of water into the first water guiding channel 3224 to improve the sealing effect.

[0064] In some embodiments, the third upper sealing lip 3223 is obliquely arranged outward relative to the second base portion 3220 in the direction towards the inner side surface 3227. The third upper sealing lip 3223 has a water blocking function to improve the sealing effect.

[0065] After the sky door 21 and the ground door 22 are closed, the first upper sealing lip 3221 first inhibits the impact of water outside the vehicle, which can achieve a large amount of water blocking and water guiding effects; when the sealing of the first upper sealing lip 3221 fails, the water will be discharged outside the vehicle along the first water guiding channel 3224; when the water in the first water guiding channel 3224 crosses the second upper sealing lip 3222 and enters the second water guiding channel 3225, it will be discharged outside the vehicle along the second water guiding channel 3225.

[0066] The waterproofness of the sealing assembly 3 is higher, the water impact resistance is high, and the hydrophobic water guiding is faster; 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 seal 31, forming a closed airtight space, improving the airtightness while preventing water, and minimizing airtight leakage to the greatest extent; furthermore, the better sealing effect of the sealing assembly 3 enables it to accommodate more manufacturing deviations of the sky door 21 and the ground door 22, increasing from the conventional plus or minus 2 mm to plus or minus 4 mm, which is beneficial to the processing and manufacturing of the sky door 21 and the ground door 22.

[0067] See Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 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 arranged in sequence.

[0068] See Figure 13 , in the first sealing position, the sky door 21 is directly attached and sealed to the first seal 31. In this position, the sky door 21 is attached and sealed to the first lower sealing lip 312 and the second lower sealing lip 313.

[0069] See Figure 14 , in the second sealing position, the second seal 32 is located between the sky door 21 and the first seal 31. In this position, the first upper sealing lip 3221 is attached and sealed to the first lower sealing lip 312, and the third upper sealing lip 3223 is attached and sealed to the second lower sealing lip 313.

[0070] See Figure 15, at the third sealing position, the second seal 32 is located between the top door 21 and the first seal 31. In this position, the first upper sealing lip 3221 is in sealing contact with the first lower sealing lip 312, the second upper sealing lip 3222 is in sealing contact with the first base 311, and the third upper sealing lip 3223 is in sealing contact with the second lower sealing lip 313, so as to form a first water guiding channel 3224 and a second water guiding channel 3225 on opposite sides of the second upper sealing lip 3222.

[0071] Refer Figure 16 , at the fourth sealing position, the first seal 31 and the second seal 32 are respectively located on the upper and lower sides of the bottom door 22 and are both in sealing contact with the bottom door 22. The first upper sealing lip 3221, the second upper sealing lip 3222 and the third upper sealing lip 3223 are in sealing contact with the bottom door 22; the first lower sealing lip 312 and the second lower sealing lip 313 are in sealing contact with the bottom door 22.

[0072] At the fifth sealing position, the first seal 31 and the second seal 32 are respectively located on the upper and lower sides of the bottom door 22 and are both in sealing contact with the bottom door 22. The main body seal 321 is in sealing contact with the bottom door 22; the first lower sealing lip 312 and the second lower sealing lip 313 are in sealing contact with the bottom door 22.

[0073] Refer Figure 17 、 Figure 18 And Figure 19 , the sealing assembly 3 includes a first fixing member 33 fixed to the corner seal 322. The first fixing member 33 is fixed to the top door 21.

[0074] In some embodiments, the corner seal 322 is assembled and fixed to the first fixing member 33. In other embodiments, the corner seal 322 and the first fixing member 33 are integrally provided. For example, the corner seal 322 is injection molded on the first fixing member 33.

[0075] The second base 3220 is hollow to provide a deformation space for the second base 3220 to improve the sealing effect.

[0076] The second base 3220 includes a bottom wall 32281 and an arc-shaped side wall 32282 connected to the bottom wall 32281. The bottom wall 32281 and the side wall 32282 enclose a receiving cavity 32283. The first upper sealing lip 3221, the second upper sealing lip 3222 and the third upper sealing lip 3223 extend from the side wall 32282.

[0077] The second base portion 3220 includes a plurality of bosses 32284 extending from the side wall 32282 into the receiving cavity 32283.

[0078] The bottom wall 32281 is provided with a first through hole 32285, a pair of second through holes 32286, and a pair of third through holes 32287. In some embodiments, the first through hole 32285 is located on one side in the width direction of the bottom wall 32281, the pair of second through holes 32286 are respectively located on both sides in the length direction of the first through hole 32285, and the pair of third through holes 32287 are respectively located inside the pair of first through holes 32285.

[0079] In some embodiments, the first through hole 32285 is in a long strip shape, and the pair of second through holes 32286 communicate with the first through hole 32285 to form a U-shaped through hole. The pair of third through holes 32287 are located in the U-shaped space surrounded by the U-shaped through hole.

[0080] The first fixing member 33 includes a substrate portion 331 and a first bump 332, a pair of second bumps 333, and a pair of first clamping portions 334 extending from the substrate portion 331. The substrate portion 331 is located in the receiving cavity 32283. The plurality of bosses 32284 are used to support the substrate portion 331. The first bump 332 is in a long strip shape and is located in the first through hole 32285, and the pair of second bumps 333 are respectively located in the pair of second through holes 32286.
