Description

Technical Field

[0001] This invention belongs to the field of automotive technology, specifically relating to a sealing device for a locking mechanism and a vehicle. Background Technology

[0002] With the continuous rise of the automotive industry, people's demands for car comfort are increasing. The elimination of the B-pillar, creating a larger doorway, provides customers with a significantly improved riding experience and easier entry and exit. It also greatly enhances the expansion of interior space, visually bridging the gap between the front and rear rows and providing users with a better driving experience. Therefore, whether it's enriching users' travel scenarios or increasing the enjoyment of travel, in-depth research into B-pillarless vehicle bodies is necessary.

[0003] Traditional B-pillarless doors and sliding doors share the same structure as traditional B-pillar sliding doors, but there are substantial differences in the front doors. For example, because the side door openings of traditional vehicles are separated into front and rear door openings by the B-pillar, the central locking position of the front and rear doors with a B-pillar is fixed to the B-pillar, resulting in a mature and stable structure. However, in B-pillarless vehicles, the central locking is located on the rear sliding door, and the single-lock connection between the two moving parts leads to poor stability, making it difficult to control the matching gap between the door and surrounding components. Adding upper and lower locks to the side panel connection and fixation is crucial for door stability. Previously, the seal between the door and the body at the upper part of the B-pillar was a complete and continuous sealing surface. However, due to the addition of a lock near the B-pillar on the front door, difficulties arise in matching the seal between the front door and the side door openings.

[0004] Therefore, a sealing device and vehicle are needed for the locking mechanism to achieve sealing at the B-pillar-less locking mechanism. Summary of the Invention

[0005] To address some or all of the aforementioned technical problems existing in the prior art, this invention proposes a sealing device for the locking mechanism and a vehicle. This sealing device is used to seal the locking tongue engagement point of the vehicle, ensuring a sealing effect and preventing water leakage.

[0006] According to one aspect of the present invention, a sealing device for the locking portion is provided, comprising:

[0007] A side panel, having a side panel receiving portion formed thereon, and a locking latch body fixed to the side panel.

[0008] A side sealing strip, which is fixed to the side panel and located at the side panel receiving portion.

[0009] The door panel has a cavity for accommodating a locking block, and the upper end of the door panel is configured to press against the side sealing strip when the door is closed.

[0010] A locking sleeve is provided, a portion of which is disposed in the receiving cavity, and the locking sleeve forms a seal between the door sheet metal and the side sealing strip, as well as between the door sheet metal and the latch body.

[0011] In one embodiment, the side enclosure receiving portion is formed by the side enclosure in a direction toward the first side and recessed downwards, and the side enclosure sealing strip includes:

[0012] Bubble-shaped side sealing strip body,

[0013] A side sealing mounting portion is constructed on the outer wall surface of the first side of the main body of the side sealing strip, the side sealing mounting portion being used for adhesive fixing to the side.

[0014] A side-sealing folded edge portion extending from the side-sealing mounting portion along the side-sealing receiving portion toward the second side.

[0015] A side sealing bubble lip extends from the wall of the second side of the side sealing strip body towards the first side. When the door is closed, the side sealing bubble lip is squeezed and deformed to fit onto the side of the side at the side sealing fold, forming a closed cavity with the side sealing fold and the side sealing strip body.

[0016] In one embodiment, the wall structure of the side sealing strip body facing the side sealing fold is a side sealing bend that is recessed into the side sealing strip body.

[0017] In one embodiment, the side sealing strip body extends toward a first side to form a side sealing drape for covering the sheet metal stop of the side.

[0018] In one embodiment, a first sealing lip is provided on the wall of the second side of the locking sleeve. The first sealing lip abuts against the side sealing strip when the door is closed. The wall of the second side of the locking sleeve is connected to the door sheet metal through at least one sealing lip. When the door is closed, the locking sleeve, the door sheet metal and the side sealing strip form a closed cavity. The lowest end of the closed cavity is located on the side close to the door sheet metal.

[0019] In one embodiment, a lock body sealing lip is provided on the wall of the first side of the locking sleeve, and the lock body sealing lip is used to abut against the lock body.

[0020] In one embodiment, the device further includes a door opening sealing strip fixed to the side panel, on which a bubble tube is provided. In the closed state, the wall of the first side of the locking sleeve presses against the bubble tube. A water channel with an opening facing the bubble tube is provided on the wall of the first side of the locking sleeve, and the inner cavity of the water channel communicates with the inner cavity of the locking sleeve.

[0021] In one embodiment, the door sheet metal is constructed in a V-shape on the YZ section, and a clamping groove is provided on the wall of the first side of the locking sleeve, the wall of the first side of the door sheet metal extending into the clamping groove.

[0022] In one embodiment, a water-blocking portion conforming to the door sheet metal is provided on the wall of the first side of the locking sleeve, and the water-blocking portion is provided with multiple water-blocking lips for abutting against the door sheet metal.

[0023] According to another aspect of the invention, a vehicle is provided that includes the sealing device described above for the locking portion.

[0024] Compared with the prior art, the advantages of the present invention are as follows: The sealing device at the locking point of this application is applied to the locking point between the door and the side panel to achieve sealing. By setting a side panel sealing strip on the side panel as a first sealing treatment to isolate the inside and outside of the vehicle body, if water enters the inside of the vehicle body by passing through the side panel sealing strip as the first seal, it is blocked by the locking sleeve to prevent it from entering the receiving cavity of the door sheet metal. At the latch body, the locking sleeve continues to prevent water from entering the inner cavity of the vehicle. Through multiple seals, the waterproof sealing of the vehicle is effectively guaranteed. Attached Figure Description

It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.

[0036] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] It is easy to understand that, in order to ensure the stability of a car door without a B-pillar, a lock is installed between the door and the side panel. This application further improves the locked side panel and the door sheet metal to achieve a seal between the door and the side panel at the lock point. Embodiments of this invention propose a sealing device at the lock point. For example... Figures 1 to 4 As shown, the sealing device at the locking point includes a side panel 2, a side panel sealing strip 10, a door sheet metal 1, and a locking sleeve 6. A side panel receiving portion 9 is formed on the side panel 2 for housing the side panel sealing strip 10. Additionally, a latch body 5 is fixed to the side panel 2. This latch body 5 is part of the locking mechanism and is used to achieve the locking connection. The side panel sealing strip 10 is fixed to the side panel 2 and located at the side panel receiving portion 9. The door sheet metal 1 has a receiving cavity 4. This receiving cavity 4 is mainly used to accommodate and fix the locking block 7, so that in the closed state, the locking block 7 extends out of the door and matches with the latch body 5 to form a locking connection. The upper end of the door sheet metal 1 is positioned to match the side panel receiving portion 9, so that in the closed state, the side panel sealing strip 10 is compressed, thereby forming a seal between the door sheet metal 1 and the side panel 2. The locking sleeve 6 is disposed in the receiving cavity 4. The locking sleeve 6 forms a seal between the door sheet metal 1 and the side sealing strip 10 to prevent water from flowing through the gap between the side sealing strip 10 and the door sheet metal 1 when the door is closed. At the same time, the locking sleeve 6 also forms a seal between the door sheet metal 1 and the latch body 5 to prevent water that has entered the receiving cavity 4 of the locking sleeve 6 from entering the interior cavity of the vehicle through the latch body 5.

[0038] Therefore, this application provides a sealing device for the locking point, which can form an effective seal at the locking point to prevent water from entering the vehicle's interior cavity through this point. Specifically, firstly, a seal is formed between the door and the side panel 2 by the side panel sealing strip 10, preventing water from entering the vehicle's interior cavity when the door is closed. Secondly, a seal is achieved between the door and the side panel sealing strip 10 by the locking sleeve 6, preventing water from entering the receiving cavity 4 of the door sheet metal 1. Furthermore, the locking sleeve 6 also achieves a seal between the door sheet metal 1 and the latch body 5, preventing water from entering the vehicle's interior cavity through the latch body 5. It is evident that the sealing device for the locking point of this application can form effective seals at multiple locations, thereby ensuring the vehicle's sealing at the locking point.

[0039] In one embodiment, the side panel receiving portion 9 is formed by a downward recess from the side panel 2 toward a first side (aligned with the inward direction of the vehicle itself). Structurally, the side panel sealing strip 10 includes a side panel sealing strip body 16, a side panel sealing mounting portion 12, a side panel sealing folded portion 11, and a side panel sealing bubble lip 13. The side panel sealing strip body 16 can be configured as a bubble. The side panel sealing mounting portion 12 is constructed on the outer wall surface of the first side of the side panel sealing strip body 16. The side panel sealing mounting portion 12 is used to fix to the side panel 2. For example, the side panel sealing mounting portion 12 can be fixed to the side wall of the side panel 2 by adhesive and snap fastening. The side panel sealing folded portion 11 extends from the side panel sealing mounting portion 12 along the side panel receiving portion 9 toward a second side (aligned with the outer side of the vehicle itself) and upward. The side panel sealing bubble lip 13 extends from the wall of the second side of the side panel sealing strip body 16 toward the first side and upward. With the door closed, the side sealing bubble 13 is compressed and deformed, fitting against the side wall 2 at the side sealing fold 11. It is evident that the side sealing fold 11 serves two purposes: firstly, it can abut against the outer wall of the side wall through its supporting portion, achieving a sealing and waterproofing function; secondly, it can cooperate with the side sealing bubble 13, compressing and deforming it after the door is closed, thus fitting against the fold 11 to achieve a waterproof seal, and forming a closed surface, which is beneficial for the overall appearance. Figure 2 The dotted line in the diagram indicates the modified shape of the side sealing bubble lip 13.

[0040] In one embodiment, the wall of the side sealing strip body 16 facing the side sealing flange 11 is constructed with a side sealing bend 14. The side sealing bend 14 bends into the inner cavity of the side sealing strip body 16. This side sealing bend 14 forms an inner groove, which facilitates the flow of water from the outer wall of the side 2 into the side sealing strip 10 and outwards to the front and rear sides of the vehicle body, preventing water accumulation. After the door is opened, the side sealing bubble lip 13 of the side sealing strip 10 springs open outwards, and water slides into the groove at the sealing bend 14, avoiding the risk of water pouring into the passenger compartment.

[0041] In one embodiment, the side sealing strip body 16 extends protrudingly to the first side to form a side sealing vent 15. This side sealing vent 15 can cover the sheet metal stop of the side panel 2. Therefore, by covering the sheet metal stop of the side panel 2 with the side sealing vent 15, the aesthetic appearance can be effectively guaranteed.

[0042] In one embodiment, the locking sleeve 6 has a sleeve body 25, which is placed in the receiving cavity 4. The locking sleeve also has a first sealing lip 21. The first sealing lip 21 is formed by the sleeve body 25 extending to the second side and upward. In the closed state, the first sealing lip 21 of the locking sleeve 6 abuts against the side sealing bubble lip 13 and forms a closed cavity 8 with the door sheet metal 1. Water may enter through the gap between the door sheet metal 1 and the side sealing strip 10. By providing the first sealing lip 21, water can be effectively prevented from entering the vehicle through the side sealing strip 10 via the side sealing strip 10.

[0043] Additionally, the second side wall of the locking sleeve 6 is connected to the door sheet metal 7 via at least one sealing lip. Preferably, three sealing lips are provided between the second side wall of the locking sleeve 6 and the door sheet metal 1, namely the second sealing lip 22, the third sealing lip 23, and the fourth sealing lip 24. These three sealing lips can form a multi-seal, ensuring a good fit with the door sheet metal 1, thereby improving the sealing effect. More preferably, the lowest point inside the closed cavity 8 is located on the side with the three sealing lips, that is, the side with the second sealing lip 22 is lower than the side with the first sealing lip 21. In operation, when rainwater seeps into the closed cavity 8 through the side sealing bubble lip 13, the water flows through the inner panel 33 of the door sheet metal 1 and slides down to the second sealing lip 22. The multiple sealing lips provided on the locking sleeve 6 can effectively prevent water from pouring in. Under the isolation and guiding effect of the second sealing lip 22 and the third sealing lip 23, only a small amount of water may enter the receiving cavity 4 through the fourth sealing lip 24. During production, the sealing lips 21, 22, 23, and 24 are integrated with the locking sleeve body 25 through secondary injection molding.

[0044] There is a possibility that water flow could enter the vehicle through the outer wall of side panel 2 and the side panel stop, such as... Figure 3 As shown, a lock body sealing lip 26 is added to the locking sleeve 6 to abut against the latch body 5, forming a water-blocking lip to prevent water from directly intruding into the compartment. Specifically, a lock body sealing lip 26 is provided on the wall of the first side of the locking sleeve 6. In the closed state, the lock body sealing lip 26 is used to abut against the latch body 5.

[0045] In one embodiment, a door opening sealing strip 3 is also provided on the side panel 2. A bubble tube portion 101 is provided on the door opening sealing strip 3. In the closed state, the wall of the first side of the locking sleeve 6 compresses the bubble tube portion 101. Additionally, a water channel 31 with an opening facing the bubble tube portion 101 is provided on the wall of the first side of the locking sleeve 6. The inner cavity of the water channel 31 communicates with the inner cavity of the locking sleeve 6. Therefore, in the closed state, after the bubble tube portion 101 is compressed and deformed... Figure 3The dashed line indicates the position after compression and deformation. It forms a closed space in contact with the water flow channel 31. There is a risk that the water flow may seep through the bubble tube section 101. The above arrangement allows the water flowing through the bubble tube section 101 to be collected into the water flow channel 31 and then introduced into the cavity of the locking sleeve 6 through the water flow channel 31.

[0046] The door sheet metal 1 is generally V-shaped in the YZ section. A clamping groove 32 is provided on the first side wall of the locking sleeve 6. The first side wall of the door sheet metal 1 extends into the clamping groove 32. It can be seen that the clamping groove 32 serves to assemble and connect the door sheet metal 1, and guide and limit the door sheet metal 1 in the Y direction. The clamping groove 32 itself is a plastic part.

[0047] A water-blocking part 41 is provided on the wall of the first side of the locking sleeve 6. The water-blocking part 41 conforms to the lower end of the door sheet metal receiving cavity 4. Multiple water-blocking lips are provided on the second side of the water-blocking part 41 to abut against the door sheet metal 7. For example, two water-blocking lips are provided on the water-blocking part 41, namely a first water-blocking lip 42 and a second water-blocking lip 43. The first water-blocking lip 42 blocks water from entering the bottom and leads it out to the front and rear sides of the door. A small amount of water passing through the first water-blocking lip 42 intrudes into the second water-blocking lip 43, which isolates the water flow. Since the structural design places the sheet metal mating surface inside the lock body, the risk of water leakage is minimized. In addition, the first water-blocking lip 42 and the second water-blocking lip 43, when engaged in the receiving cavity 4, can also buffer the shaking of the locking sleeve 6.

[0048] The sealing device at the locking point of this invention solves the problem of water leakage risk caused by poor water drainage and sealing at the locking overlap position. A side sealing strip is arranged on the side wall of the side panel as the first sealing treatment to isolate the inside and outside of the vehicle body. Simultaneously, a groove for collecting water can be formed on the side sealing strip. This groove guides water at the front and rear sides of the vehicle, immediately blocking water entering from the doors and side panels at the first seal (i.e., the side sealing strip) and directing it to the front and rear sides of the vehicle body through a sealed bubble tube. For water seepage that bypasses the first seal and enters the inside of the vehicle body, a waterproof overlap structure of the first to fourth sealing lips is provided on the locking sleeve to block it. For water flowing beyond the waterproof overlap of the first to fourth sealing lips, the locking sleeve has a waterproof overlap structure of the lock body sealing lips to block it. The locking sleeve not only abuts against the latch body but also has a water-collecting groove structure and a bubble tube section at the interface with the door opening sealing strip, serving as a final safety measure to isolate the wet area from the interior, improving the vehicle's waterproof sealing performance.

[0049] As can be seen, this application provides a sealing arrangement structure for the locking point without a B-pillar, which solves the problem of water leakage caused by overlapping sealing voids at the locking tongue engagement point when water flows through it. Even if water flows through the first sealing surface of the door and side panel and reaches the inner cavity of the locking point, the sealing device of this application can further avoid the risk of water leakage.

[0050] This application also relates to a vehicle. The vehicle includes the aforementioned sealing device for the locking mechanism. It is readily understood that the vehicle also possesses the technical advantages of the corresponding sealing device for the locking mechanism.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and / or modifications falling within the scope of the invention, and all changes and / or modifications made according to embodiments of the invention should be covered within the protection scope of the invention.
