Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle sealing structures, and more specifically, relates to a roof sealing structure and a vehicle. Background Art

[0002] In the design of a car body, in addition to two to four side-opening doors, there is usually a back door at the rear, such as to open the luggage compartment and facilitate the taking and placing of luggage. Currently, the traditional back door opening methods mainly include: hatchback, upper and lower opening, side opening, left and right opening. The main function of the back door is to realize the storage and covering of items in the trunk. However, the opening of the existing back door has a great demand for the space at the rear of the vehicle. When the parking space is cramped, especially when the space at the rear of the vehicle is limited and narrow, there is no movement space for the conventional back door to open. The back door cannot be opened to the normal position or angle, making it inconvenient to take and place luggage. In order to reduce the space occupied by the back door when it is open and adapt to various parking spaces, some vehicles directly connect the back door to the body in a sliding manner and locate it behind the roof. When the back door is opened, it slides above the roof, reducing the space occupied by the upper part of the vehicle.

[0003] However, since the tailgate is movable and directly connected to the rear side of the roof, a reliable sealing structure is required between the tailgate and the roof to adapt to the situation where the tailgate is frequently opened and closed, while still ensuring the sealing and waterproof effect after the tailgate is closed, thereby preventing external rainwater from entering the interior of the vehicle after the tailgate is closed.

[0004] Existing tailgate and roof sealing structures typically utilize sealing strips installed on the rear side of the roof and the front side of the tailgate. These strips define an extrusion channel along their axis. The roof and tailgate sealing strips squeeze each other, deforming the extrusion channel and achieving a seal between the strip and the vehicle body. However, the frequent opening and closing of the tailgate causes constant compression and release of the sealing strip, causing the extrusion channel to deform frequently, significantly impacting the durability of the sealing strip. As the sealing strip wears and its deformation properties diminish, its sealing performance gradually deteriorates. Once the seal fails, it can severely impact the customer's experience with the vehicle. Utility Model Content

[0005] The purpose of the utility model is to provide a roof sealing structure and a vehicle, aiming to solve the problem in the prior art that the sealing structure between the tailgate and the roof is deformed for a long time due to extrusion, resulting in the deformation of the extrusion channel that cannot be restored, thereby affecting the sealing effect.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] In a first aspect, a roof sealing structure is provided, comprising:

[0008] A ceiling sealing strip is connected to the rear side of the ceiling, and the ceiling sealing strip has a deformation channel along its extension path;

[0009] The back door sealing strip is connected to the front side of the back door. The back door sealing strip is a non-hollow component. When the back door is closed, the back door sealing strip abuts against the ceiling sealing strip in the front-to-back direction.

[0010] In conjunction with the first aspect, in one possible implementation, the roof sealing strip includes:

[0011] a first sealing body connected to the rear side of the ceiling, wherein the deformation channel is provided in the first sealing body;

[0012] a first extension portion connected to the front side of the first sealing body and attached to the bottom of the ceiling; and

[0013] The guide portion is connected to the bottom of the first sealing body and is arranged to be inclined toward the rear side.

[0014] In conjunction with the first aspect, in one possible implementation, the back door sealing strip includes:

[0015] A second sealing body connected to the front side of the back door, used for abutting and sealing against the roof sealing strip; and

[0016] The second extension portion is connected to the rear side of the second sealing body and is attached to the bottom of the back door. Both the second sealing body and the second extension portion are non-hollow components.

[0017] In combination with the first aspect, in a possible implementation, the roof sealing structure also includes a reinforcing sealing strip located between the bottom frame of the vehicle body and the tailgate, the reinforcing sealing strip having an extrusion channel extending along its own axis, and the reinforcing sealing strip abuts against the tailgate in the up and down directions.

[0018] In combination with the first aspect, in a possible implementation, the reinforced sealing strip includes a third sealing body and a sealing sheet arranged on the top of the third sealing body, the third sealing body is connected to the bottom frame of the vehicle body, the extrusion channel is opened in the third sealing body, and the sealing sheet abuts against the tail door sealing strip or the tail door.

[0019] In combination with the first aspect, in a possible implementation, the cross-section of the reinforced sealing strip is a triangular structure, and the bottom side of the triangular structure is connected to the bottom frame of the vehicle body.

[0020] In combination with the first aspect, in a possible implementation, the roof sealing structure further includes a frame sealing strip connected to the bottom frame of the vehicle body, and the top of the frame sealing strip abuts against the bottom of the tailgate.

[0021] In conjunction with the first aspect, in a possible implementation, the frame sealing strip includes:

[0022] a fourth sealing body having a sealing passage formed along its extension path, the fourth sealing body being located between the vehicle body bottom frame and the tailgate in the vertical direction and abutting against the tailgate; and

[0023] The mounting portion is connected to the bottom of the fourth sealing body. The mounting portion is provided with a mounting groove, and the vehicle body bottom frame is inserted into the mounting groove.

[0024] The roof sealing structure provided by the present invention has the following advantages: compared with the prior art, the back door sealing strip of the present invention is a non-hollow component, while the roof sealing strip has a deformation channel along its extension path. When the back door is closed, the back door sealing strip abuts the rear side of the roof sealing strip, causing both the roof and back door sealing strips to deform under the compressive force. Due to the deformation channel, the roof sealing strip has a greater deformation capacity, reducing the gap between the roof and back door sealing strips, improving sealing efficiency, and simultaneously reducing the problem of damage caused by rigid compressive force between the back door and the roof. The back door sealing strip of the present invention is a non-hollow component, with a smaller deformation capacity, and can quickly recover after the force is removed; while the roof sealing strip has a larger deformation capacity due to the deformation channel. The back door sealing strip and the roof sealing strip work together to effectively avoid the problem of both the roof and back door sealing strips having a large deformation capacity, which can cause the roof and back door sealing strips to be unable to recover after long-term compressive deformation, resulting in poor sealing effect.

[0025] In a second aspect, an embodiment of the present invention further provides a vehicle, comprising the roof sealing structure described above.

[0026] In combination with the second aspect, in a possible implementation, the vehicle's body bottom frame is provided with a water flow trough that runs through in the left and right directions. The water flow trough is correspondingly arranged below the roof sealing strip and the tail door sealing strip, and is used to discharge water in the left and right directions.

[0027] The vehicle provided by the present invention has the following beneficial effects: Compared with the prior art, the vehicle of the present invention adopts the above-mentioned roof sealing structure, wherein the back door sealing strip is a non-hollow component, while the roof sealing strip has a deformation channel along its extension path. When the back door is closed, the back door sealing strip abuts the rear side of the roof sealing strip, causing both the roof sealing strip and the back door sealing strip to deform under the extrusion force. Because the roof sealing strip has a deformation channel, it has a greater deformation, reducing the gap between the roof sealing strip and the back door sealing strip, improving sealing efficiency, and at the same time, reducing the problem of damage caused by rigid extrusion force between the back door and the roof. The back door sealing strip of the present invention is a non-hollow component, has a smaller deformation, and can quickly recover after the force is removed; while the roof sealing strip has a deformation channel, has a larger deformation. The back door sealing strip and the roof sealing strip cooperate to effectively avoid the problem of both the roof sealing strip and the back door sealing strip having a large deformation, which can cause the roof sealing strip and the back door sealing strip to be unable to recover after long-term extrusion deformation, resulting in poor sealing effect.

[0033] See also Figure 1 The roof sealing structure and vehicle provided by the present invention are now described. The roof sealing structure includes a roof sealing strip 3 and a tailgate sealing strip 4. The roof sealing strip 3 is connected to the rear side of the roof 2 and has a deformation channel 304 along its extension path. The tailgate sealing strip 4 is connected to the front side of the tailgate 1. The tailgate sealing strip 4 is a non-hollow member. When the tailgate 1 is closed, the tailgate sealing strip 4 abuts the roof sealing strip 3 in the front-to-back direction.

[0034] Compared to the prior art, the roof sealing structure provided by the present invention features a non-hollow back door sealing strip 4, while the roof sealing strip 3 has a deformation channel 304 along its extension path. When the back door 1 is closed, the back door sealing strip 4 abuts the rear side of the roof sealing strip 3, causing both the roof sealing strip 3 and the back door sealing strip 4 to deform under the compressive force. The deformation channel 304 allows the roof sealing strip 3 to deform more, reducing the gap between the roof sealing strip 3 and the back door sealing strip 4 and improving sealing efficiency. This also reduces the risk of damage between the back door 1 and the roof 2 caused by rigid compressive force. The back door sealing strip 4 of the present invention is a non-hollow component with a small deformation, and can quickly recover its deformation after the force is stopped; while the ceiling sealing strip 3 is provided with a deformation channel 304, and has a large deformation. The cooperation between the back door sealing strip 4 and the ceiling sealing strip 3 can effectively avoid the problem that both the ceiling sealing strip 3 and the back door sealing strip 4 have a large deformation, resulting in the ceiling sealing strip 3 and the back door sealing strip 4 being unable to recover after long-term extrusion deformation, resulting in poor sealing effect.

[0035] Specifically, the roof weather strip 3 and the back door weather strip 4 are both flexible components, such as rubber components.

[0036] In some embodiments, see Figure 1 The ceiling sealing strip 3 includes a first sealing body 301, a first extension portion 302 and a guide portion 303. The first sealing body 301 is connected to the rear side of the ceiling 2, and the deformation channel 304 is opened in the first sealing body 301; the first extension portion 302 is connected to the front side of the first sealing body 301 and is attached to the bottom of the ceiling 2; the guide portion 303 is connected to the bottom of the first sealing body 301 and is inclined toward the rear side.

[0037] The first sealing body 301 is attached to the rear side of the roof 2. When the tailgate 1 is closed, the tailgate sealing strip 4 abuts against the first sealing body 301, causing the first sealing body 301 to deform under stress. Since the deformation channel 304 is provided in the first sealing body 301, the first sealing body 301 has a greater deformation. This not only reduces the gap between the first sealing body 301 and the tailgate sealing strip 4, improving the sealing effect, but also acts as a buffer, preventing damage caused by rigid contact between the tailgate 1 and the roof 2. The first extension portion 302 is attached to the bottom of the roof 2, increasing the contact area between the roof sealing strip 3 and the roof 2 and improving the firmness of the connection. In this embodiment, a guide portion 303 is also provided. Since the guide portion 303 is tilted toward the rear, it can guide any remaining water between the first sealing body 301 and the tailgate sealing strip 4 toward the rear when the tailgate 1 is opened, preventing it from entering the vehicle.

[0038] Optionally, the first sealing body 301 and the first extending portion 302 are both bonded to the ceiling 2 .

[0039] In some embodiments, see Figure 1 The back door sealing strip 4 includes a second sealing body 401 and a second extension portion 402. The second sealing body 401 is connected to the front side of the back door 1 and is used to abut and seal with the ceiling sealing strip 3; the second extension portion 402 is connected to the rear side of the second sealing body 401 and is attached to the bottom of the back door 1. The second sealing body 401 and the second extension portion 402 are both non-hollow components.

[0040] In this embodiment, both the second sealing member 401 and the second extension 402 are non-hollow components, resulting in minimal deformation. This allows for elastic contact with the roof sealing strip 3, preventing damage to the back door 1 and roof 2. This also prevents significant deformation from causing a decrease in elastic recovery after long-term use, leading to poor sealing. Furthermore, both the second sealing member 401 and the second extension 402 are connected to the back door 1, increasing the contact area with the back door 1 and enhancing the secure connection.

[0041] Optionally, the second sealing body 401 and the second extending portion 402 are both adhered to the back door 1 .

[0042] In some embodiments, see Figure 1 The roof sealing structure also includes a reinforcing sealing strip 5 located between the vehicle body bottom frame 7 and the back door 1. The reinforcing sealing strip 5 has a through extrusion channel 503 opened along its own axial direction, and the reinforcing sealing strip 5 abuts against the back door 1 in the up and down directions.

[0043] This embodiment incorporates a reinforced sealing strip 5 between the underbody frame and tailgate 1 to further enhance the sealing effect of the vehicle's roof when the tailgate 1 is closed. This reinforced sealing strip 5 abuts the tailgate 1, preventing dust or water from entering the vehicle interior through the gap between the tailgate 1 and the underbody frame 7 in the event of a seal failure between the roof sealing strip 3 and the tailgate sealing strip 4. Furthermore, the reinforced sealing strip 5 reduces interior noise and improves NVH performance.

[0044] Optionally, the reinforcing sealing strip 5 is a flexible component, such as a rubber component.

[0045] In some embodiments, see Figure 1 The reinforced sealing strip 5 includes a third sealing body 501 and a sealing piece 502 arranged on the top of the third sealing body 501. The third sealing body 501 is connected to the bottom frame 7 of the vehicle body. The extrusion channel 503 is opened in the third sealing body 501. The sealing piece 502 abuts against the tail door sealing strip 4 or the tail door 1.

[0046] The third sealing member 501 is connected to the underframe 7 of the vehicle body. A sealing sheet 502, located at the top of the third sealing member 501, abuts against the tailgate sealing strip 4 or tailgate 1. When the tailgate 1 is closed, friction between the tailgate 1 or tailgate sealing strip 4 and the sealing sheet 502 is generated. This prevents wear on the third sealing member 501, which could lead to the extrusion channel 503 being exposed to the outside and causing sealing failure of the reinforced sealing strip 5. Furthermore, the design of the sealing sheet 502 not only improves the sealing effect, but also reduces friction compared to the entire third sealing member 501 contacting the tailgate 1 or tailgate sealing strip 4.

[0047] In some embodiments, see Figure 1 The cross section of the reinforcing sealing strip 5 is a triangular structure, and the bottom side of the triangular structure is connected to the bottom frame 7 of the vehicle body.

[0048] Since the triangle is stable, the solution in this embodiment can avoid the problem of large-scale deformation of the reinforced sealing strip 5 during the opening and closing process of the tailgate 1, which makes it difficult to restore. At the same time, the bottom edge of the triangular structure is connected to the bottom frame 7 of the vehicle body, increasing the contact area with the bottom frame 7 of the vehicle body, thereby ensuring the firmness of the connection.

[0049] Optionally, the reinforced sealing strip 5 is bonded to the vehicle body bottom frame 7 .

[0050] In some embodiments, see Figure 1 The roof sealing structure further includes a frame sealing strip 6 connected to the vehicle body bottom frame 7 , and the top of the frame sealing strip 6 abuts against the bottom of the back door 1 .

[0051] The frame seal 6 abuts the tailgate 1 and the underbody frame 7, further isolating the vehicle interior from the outside. If the roof seal 3 and tailgate seal 4 fail, water or dust is trapped in front of the frame seal 6, preventing it from entering the vehicle. Furthermore, the frame seal 6, roof seal 3, and tailgate seal 4 work together to reduce interior noise and improve vehicle NVH performance.

[0052] In some embodiments, see Figure 1 The frame sealing strip 6 includes a fourth sealing body 601 and an installation portion 602. The fourth sealing body 601 has a sealing channel 603 along its own extension path. The fourth sealing body 601 is located between the vehicle body bottom frame 7 and the tailgate 1 in the up and down directions and abuts against the tailgate 1. The installation portion 602 is connected to the bottom of the fourth sealing body 601. The installation portion 602 has an installation groove, and the vehicle body bottom frame 7 is inserted into the installation groove.

[0053] In this embodiment, a mounting groove is defined in the mounting portion 602, into which the underframe 7 is inserted. This increases the contact area compared to a single-sided adhesive solution, making the connection between the mounting portion 602 and the underframe 7 more stable and secure. The fourth sealing member 601 defines a sealing channel 603, which increases deformation, preventing excessive friction between the tailgate 1 and the fourth sealing member 601 when opening or closing, which could cause severe wear on the tailgate 1 and thus extend its service life.

[0054] It should be noted that the vehicle body bottom frame 7 includes support frames spaced apart in the left-right direction and a connecting frame connecting the two support frames, the connecting frame being correspondingly arranged below the connection between the back door 1 and the roof 2. The rear side of the connecting frame is inserted into the mounting groove.

[0055] Optionally, the fourth sealing body 601 and the mounting portion 602 are an integral component. Both sides of the vehicle body bottom frame 7 are bonded to the mounting portion 602 .

[0056] Based on the same inventive concept, the present invention also provides a vehicle. Figure 1 , the vehicle includes any one of the above roof sealing structures.

[0057] The vehicle provided by the present invention utilizes the aforementioned roof sealing structure. The tailgate sealing strip 4 is a non-hollow member, while the roof sealing strip 3 defines a deformation channel 304 along its extension path. When the tailgate 1 is closed, the tailgate sealing strip 4 abuts the rear side of the roof sealing strip 3, causing both the roof sealing strip 3 and the tailgate sealing strip 4 to deform under the compressive force. The presence of the deformation channel 304 in the roof sealing strip 3 allows for greater deformation, reducing the gap between the roof sealing strip 3 and the tailgate sealing strip 4 and improving sealing efficiency. This also reduces the risk of damage between the tailgate 1 and the roof 2 caused by rigid compressive force. The back door sealing strip 4 of the present invention is a non-hollow component with a small deformation, and can quickly recover its deformation after the force is stopped; while the ceiling sealing strip 3 is provided with a deformation channel 304, and has a large deformation. The cooperation between the back door sealing strip 4 and the ceiling sealing strip 3 can effectively avoid the problem that both the ceiling sealing strip 3 and the back door sealing strip 4 have a large deformation, resulting in the ceiling sealing strip 3 and the back door sealing strip 4 being unable to recover after long-term extrusion deformation, resulting in poor sealing effect.

[0058] In some embodiments, see Figure 1 The vehicle's body bottom frame 7 is provided with a water flow trough 701 that runs through in the left and right directions. The water flow trough 701 is correspondingly arranged below the roof sealing strip 3 and the back door sealing strip 4, and is used to discharge water in the left and right directions.

[0059] The water channel 701 receives water flowing in from the roof and tailgate sealing strips 3 and 4, preventing any water remaining between them from entering the vehicle interior when the tailgate 1 is opened, or preventing water from entering the vehicle interior directly if the seal between the roof and tailgate sealing strips 3 and 4 fails. Furthermore, this embodiment not only receives water but also drains the water from the channel outwards from both ends, preventing water accumulation and overflow.

[0060] Optionally, the guide portion 303 is used to guide water flow into the water flow channel 701.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
