Description

Technical Field

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

[0002] In automobile design, in addition to two to four side-opening doors, there's usually a tailgate at the rear, for example, to access the trunk and facilitate access to luggage. Traditional tailgate opening styles include hatchback, split-open, side-open, and split-open. The main function of a tailgate is to provide a cover for storing items in the trunk.

[0003] However, conventional tailgate opening requires a lot of space at the rear of the vehicle. When parking is tight, especially in a narrow or restricted area at the rear of the vehicle, the tailgate cannot be opened to the correct position or angle, making it difficult to put or take luggage. To reduce the space occupied by the tailgate when open and accommodate various parking spaces, some vehicles have tailgates that are directly connected to the vehicle body and located behind the roof. This allows the tailgate to slide above the roof when opened, thus reducing the space occupied by the upper part of the vehicle.

[0004] For a sliding tailgate structure, the tailgate is directly connected to the rear side of the ceiling. When opening, the tailgate is first raised above the ceiling, and then slid along the slide rails provided on the inside of the ceiling above the ceiling to open the tailgate. Since the slide rails need to be provided on the inside of the ceiling, the movement of the tailgate above the ceiling requires the connecting hinges to slide along the slide rails. If the ceiling is set as an integral structure, the connecting hinges cannot extend out of the ceiling to connect to the tailgate, resulting in interference between the connecting hinges and the ceiling. However, if an escape groove is provided on the ceiling, impurities such as rainwater from the outside will enter the vehicle through the escape groove, which will not only affect the environment inside the vehicle, but also cause excessive noise inside the vehicle. Utility Model Content

[0005] The purpose of the utility model is to provide a vehicle top structure and a vehicle, aiming to solve the problem in the prior art that after the hinge and the tailgate are connected by opening an avoidance groove on the roof, the sealing performance of the vehicle top is reduced, which affects the cleanliness of the vehicle interior environment and the NVH performance of the entire vehicle.

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

[0007] In a first aspect, a vehicle roof structure is provided, comprising a roof, a side trim panel disposed outside the roof, and a vehicle body frame disposed below the roof and the side trim panel, wherein the roof and the side trim panel are respectively connected to the vehicle body frame, the vehicle body frame having a mounting groove for accommodating a slide rail, the mounting groove extending in a front-to-rear direction, and the vehicle roof structure further comprising:

[0008] a first sealing strip connected to the outer side of the roof; and

[0009] The second sealing strip is connected to the inner side of the side trim and abuts against the first sealing strip along the inner and outer directions. The first sealing strip and the second sealing strip are correspondingly arranged above the mounting groove.

[0010] In combination with the first aspect, in a possible implementation, a mounting bracket is provided at the bottom of the side trim panel, and the mounting bracket and the side trim panel form a fixing groove in the up and down directions. The second sealing strip includes a second fixing portion and a second sealing portion provided on the inner side of the second fixing portion. The second fixing portion is inserted into the fixing groove, and the second sealing portion abuts against the first sealing strip along the inner and outer directions.

[0011] In combination with the first aspect, in a possible implementation, the second fixing portion includes a fixing body and fixing lips provided on the upper and lower sides of the fixing body, the fixing lips are inclined toward the inner side of the vehicle body and abut against the side trim panel or the mounting bracket.

[0012] In combination with the first aspect, in a possible implementation, the vehicle top structure further includes a third sealing strip provided on the outer side of the side trim panel, and the third sealing strip is used to seal a gap between the side trim panel and the side panel.

[0013] In combination with the first aspect, in a possible implementation, the third sealing strip includes a third fixing portion and a third sealing portion connected to the outside of the third fixing portion, the third sealing portion extends toward the outside of the side trim panel and is used to seal the gap between the side trim panel and the side surround, the third fixing portion is located between the side trim panel and the vehicle body frame, and is connected to the side trim panel and / or the vehicle body frame.

[0014] In combination with the first aspect, in a possible implementation, the third sealing strip further includes a limiting portion located between the third fixing portion and the third sealing portion and extending downward, wherein the limiting portion abuts against an outer end of the vehicle body frame.

[0015] In combination with the first aspect, in a possible implementation, the outer side of the side trim panel has a downwardly bent sealing flange, the third sealing strip is provided with a sealing groove for accommodating the sealing flange, and the bottom end of the sealing flange is inserted into the sealing groove.

[0016] In combination with the first aspect, in a possible implementation, the third fixing portion has an upwardly protruding sealing protrusion, the sealing protrusion has an extrusion channel along its own extension path, and the sealing protrusion abuts against the bottom of the side trim.

[0017] In combination with the first aspect, in a possible implementation, the outer side of the third sealing portion is inclined upward, so that the top surface of the third sealing portion forms a guide slope.

[0018] The vehicle roof structure provided by the present invention has the following advantages: Compared to the prior art, the present invention comprises a roof and side panels disposed above a mounting slot, a slide rail mounted within the mounting slot, and connecting hinges connected to the slide rail and tailgate, respectively. When the tailgate moves above the vehicle roof, the connecting hinges pass through the gap between the roof and side panels to support and connect the tailgate, without interfering with the roof structure. To reduce the ingress of external noise and prevent water from flowing into the vehicle through the gap between the side panels and the roof, a first sealing strip is disposed on the exterior of the roof and a second sealing strip is disposed on the interior of the side panels. The abutment between the first and second sealing strips seals the side panels against the roof. Because the first and second sealing strips are deformable, as the connecting hinge moves, the first and second sealing strips separate where they contact the connecting hinge, leaving the first and second sealing strips abutting each other where they are not in contact with the connecting hinge. This ensures a clean environment within the mounting slot and prevents dust and water from entering the mounting slot and affecting the normal operation of the slide rail. Furthermore, when the tailgate is closed, it is located behind the roof, with the hinged connection fully retracted into the mounting slot. The first and second sealing strips abut inward and outward directions, sealing the gap between the side trim and the roof. This new design not only solves the problem of inconvenient rail removal and assembly in monolithic roof structures, but also improves the vehicle's sealing performance, preventing external noise and water from entering the vehicle interior, and enhancing the overall NVH performance of the vehicle.

[0019] In a second aspect, an embodiment of the present invention further provides a vehicle, comprising the vehicle top structure described above.

[0020] The vehicle provided by the present invention has the following advantages: Compared with the prior art, the present vehicle utilizes the aforementioned vehicle roof structure, with a roof and side panels positioned above the mounting slot, a slide rail mounted within the mounting slot, and connecting hinges connected to the slide rail and tailgate, respectively. When the tailgate moves above the vehicle roof, the connecting hinges pass through the gap between the roof and side panels to support and connect the tailgate, without interfering with the roof structure. To reduce the ingress of external noise and prevent water from flowing into the vehicle through the gap between the side panels and the roof, a first sealing strip is provided on the outside of the roof and a second sealing strip is provided on the inside of the side panels. The first and second sealing strips abut against each other to seal the side panels against the roof. Because the first and second sealing strips are deformable, as the connecting hinge moves, the first and second sealing strips separate where they contact the connecting hinge, leaving the first and second sealing strips abutting against each other where they are not in contact with the connecting hinge. This ensures a clean environment within the mounting slot and prevents dust and water from entering the mounting slot and affecting the normal operation of the slide rail. Furthermore, when the tailgate is closed, it is located behind the roof, with the hinged connection fully retracted into the mounting slot. The first and second sealing strips abut inward and outward directions, sealing the gap between the side trim and the roof. This new design not only solves the problem of inconvenient rail removal and assembly in monolithic roof structures, but also improves the vehicle's sealing performance, preventing external noise and water from entering the vehicle interior, and enhancing the overall NVH performance of the vehicle.

[0029] Please also refer to Figures 1 to 4The vehicle roof structure and vehicle provided by the present invention are now described. The vehicle roof structure includes a roof 1, a side trim panel 2 disposed on the outside of the roof 1, and a vehicle body frame 7 disposed below the roof 1 and the side trim panel 2. The roof 1 and the side trim panel 2 are respectively connected to the vehicle body frame 7. The vehicle body frame 7 has a mounting groove 701 for accommodating a slide rail. The mounting groove 701 extends in the front-to-back direction. The vehicle roof structure also includes a first sealing strip 4 and a second sealing strip 5. The first sealing strip 4 is connected to the outside of the roof 1; the second sealing strip 5 is connected to the inside of the side trim panel 2 and abuts against the first sealing strip 4 in the inward-outward direction. The first sealing strip 4 and the second sealing strip 5 are correspondingly disposed above the mounting groove 701.

[0030] Compared with the prior art, the vehicle roof structure provided by the present invention has a roof 1 and side trim 2 disposed above a mounting groove 701. A slide rail is installed in the mounting groove 701, and a connecting hinge is connected to the slide rail and the tailgate, respectively. When the tailgate moves above the vehicle roof, the connecting hinge passes through the gap between the roof 1 and the side trim 2 to support and connect the tailgate, without interfering with the roof structure. To reduce external noise from entering the vehicle interior and to prevent external water from flowing into the vehicle along the gap between the side trim 2 and the roof 1, a first sealing strip 4 is disposed on the outside of the roof 1 and a second sealing strip 5 is disposed on the inside of the side trim 2. The abutment between the first sealing strip 4 and the second sealing strip 5 achieves sealing between the side trim 2 and the roof 1. Because the first sealing strip 4 and the second sealing strip 5 are deformable, as the connecting hinge moves, the first sealing strip 4 and the second sealing strip 5 in contact with the connecting hinge are separated, and the first sealing strip 4 and the second sealing strip 5 not in contact with the connecting hinge abut against each other, ensuring the cleanliness of the environment in the installation groove 701 and preventing dust and water from entering the installation groove 701 and affecting the normal use of the slide rail. In addition, when the tailgate is closed, the tailgate is located at the rear side of the roof 1, and the connecting hinge is completely received in the installation groove 701. The first sealing strip 4 and the second sealing strip 5 abut against each other in the inside-outside direction, thereby sealing the gap between the opposite side trim panel 2 and the roof 1. The utility model not only solves the problem that the roof 1 is an integral structure that is inconvenient to disassemble and assemble the slide rail, but also improves the sealing performance of the vehicle, prevents external noise and water from entering the vehicle, and improves the NVH performance of the entire vehicle.

[0031] Optionally, the first sealing strip 4 and the second sealing strip 5 are both flexible components, such as rubber components.

[0032] As a specific embodiment of the first sealing strip 4, the first sealing strip 4 includes a first fixing portion 402 and a first sealing portion 401 connected to the outside of the first fixing portion 402. The first sealing portion 401 abuts the second sealing strip 5. The first fixing portion 402 is located below the ceiling 1 and bonded to the ceiling 1. The first fixing portion 402 abuts the outside of the ceiling 1. In this embodiment, the first sealing portion 401 and the first fixing portion 402 are both connected to the ceiling 1, increasing the contact area with the ceiling 1 and improving the firmness and reliability of the connection.

[0033] Optionally, the first sealing portion 401 is provided with a sealing channel along its extension path, so as to increase the deformation of the first sealing portion 401 and thereby improve the sealing performance.

[0034] It should be noted that two side trim panels 2 are symmetrically provided on the outer side of the roof 1 to make the top structure of the vehicle symmetrical and avoid air flow disturbances that cause greater resistance to vehicle driving.

[0035] In some embodiments, see Figure 3 A mounting bracket 8 is provided at the bottom of the side trim panel 2, and the mounting bracket 8 and the side trim panel 2 form a fixing groove in the up and down directions. The second sealing strip 5 includes a second fixing portion 502 and a second sealing portion 501 provided on the inner side of the second fixing portion 502. The second fixing portion 502 is inserted into the fixing groove, and the second sealing portion 501 abuts against the first sealing strip 4 along the inside-outside direction.

[0036] The mounting bracket 8 and the side trim 2 form a vertical fixing groove, into which the second fixing portion 502 is inserted to achieve installation. This embodiment increases the contact area with the second fixing portion 502, improving the securement and stability of the second fixing portion 502 after installation. Furthermore, the plug-in design also limits the second fixing portion 502 in the vertical direction, preventing it from separating from the side trim 2 due to its own weight.

[0037] Optionally, the second fixing portion 502 is bonded to the side trim panel 2 , or is bonded to the side trim panel 2 and the mounting bracket 8 at the same time.

[0038] Optionally, the mounting bracket 8 and the side trim panel 2 are an integral component.

[0039] Optionally, the second sealing portion 501 is provided with a deformation channel 5011 , and the deformation channel 5011 can increase the deformation amount of the second sealing portion 501 .

[0040] In some embodiments, see Figure 3 The second fixing portion 502 includes a fixing body 5021 and fixing lips 5022 provided on the upper and lower sides of the fixing body 5021. The fixing lips 5022 are inclined toward the inner side of the vehicle body and abut against the side trim 2 or the mounting bracket 8.

[0041] The fixed lip 5022 can increase the friction between the mounting bracket 8 and the side trim 2, stably fix the fixed body 5021 in the fixing groove, and prevent the second fixing portion 502 from separating from the fixing groove under the action of external force.

[0042] In some embodiments, see Figures 1 to 4 The vehicle top structure also includes a third sealing strip 6 provided on the outside of the side trim panel 2 , and the third sealing strip 6 is used to seal the gap between the side trim panel 2 and the side panel 3 .

[0043] The third sealing strip 6 seals the gap between the side trim panel 2 and the side panel 3 to prevent external moisture or noise from entering the vehicle, thereby improving the NVH performance of the entire vehicle.

[0044] Specifically, the side panel 3 includes a side panel 3 main body arranged on the outside of the side trim 2 and a sealing area located below the side trim 2. The sealing area can receive moisture that enters below the side trim 2 through the third sealing strip 6, thereby further improving the sealing performance.

[0045] In some embodiments, see Figure 4 The third sealing strip 6 includes a third fixing portion 602 and a third sealing portion 601 connected to the outside of the third fixing portion 602. The third sealing portion 601 extends toward the outside of the side trim 2 and is used to seal the gap between the side trim 2 and the side panel 3. The third fixing portion 602 is located between the side trim 2 and the body frame 7 and is connected to the side trim 2 and / or the body frame 7.

[0046] The third fixing portion 602 is connected to the side trim 2 or the vehicle body frame 7, and the third sealing portion 601 extends outward from the side trim 2, thereby sealing the gap between the side trim 2 and the side panel 3. Compared to solutions in which the third fixing portion 602 is connected only to the outer end of the side trim 2, this embodiment increases the connection area with the third fixing portion 602, thereby improving the firmness and reliability of the third fixing portion 602.

[0047] In some embodiments, see Figure 4 The third sealing strip 6 further includes a limiting portion 603 located between the third fixing portion 602 and the third sealing portion 601 and extending downward. The limiting portion 603 abuts against the outer end of the vehicle body frame 7 .

[0048] The limiting portion 603 abuts against the vehicle body frame 7, which can limit the third sealing strip 6 in the inner and outer directions. When installing the third sealing strip 6, the limiting portion 603 abuts against the outer side of the vehicle body frame 7, and the third fixing portion 602 fits against the vehicle body frame 7 or the side trim panel 2, so there is no need to locate its installation position, which improves the installation efficiency and ensures the reliability of the position of the third sealing strip 6.

[0049] In some embodiments, see Figure 4The outer side of the side trim 2 has a downwardly bent sealing flange 201, and the third sealing strip 6 is provided with a sealing groove for accommodating the sealing flange 201, and the bottom end of the sealing flange 201 is inserted into the sealing groove.

[0050] The sealing flange 201 is inserted into the sealing groove. On the one hand, it can improve the sealing performance between the side trim panel 2 and the third sealing strip 6, and prevent external moisture and dust from entering the gap between the side trim panel 2 and the vehicle body frame 7. On the other hand, it can also limit the third sealing strip 6 in the inward and outward directions, and improve the stability of the third sealing strip 6 after it is fixed.

[0051] In some embodiments, see Figure 4 The third fixing portion 602 has an upwardly protruding sealing protrusion 6021 . The sealing protrusion 6021 has an extrusion channel along its own extension path, and the sealing protrusion 6021 abuts against the bottom of the side trim 2 .

[0052] The sealing protrusion 6021 abuts against the bottom of the side trim 2. Since the sealing protrusion 6021 is provided with an extrusion channel, the sealing protrusion 6021 is more easily deformed relative to the solid component, thereby achieving extrusion sealing with the side trim 2 and improving the sealing performance.

[0053] In some embodiments, see Figure 1 and Figure 4 The outer side of the third sealing portion 601 is tilted upward, so that the top surface of the third sealing portion 601 forms a guide slope.

[0054] Since the outer side of the third sealing part 601 is inclined upward, when the water falls into the guide slope, it flows downward along the guide slope under the action of its own gravity until it flows into the space between the guide west door and the side trim panel 2, avoiding the chance of water entering the vehicle through the side panel 3 and the outer edge of the third sealing part 601, thereby improving the reliability of the seal.

[0055] Based on the same inventive concept, the present invention also provides a vehicle. Figure 1 , the vehicle includes the above-mentioned vehicle top structure.

[0056] The vehicle provided by the present invention adopts the above-mentioned vehicle roof structure. A roof 1 and side trim 2 are arranged above the mounting groove 701. A slide rail is installed in the mounting groove 701. A connecting hinge is connected to the slide rail and the tailgate, respectively. When the tailgate moves above the vehicle roof, the connecting hinge passes through the gap between the roof 1 and the side trim 2 to support and connect the tailgate without interfering with the roof structure. To reduce external noise from entering the vehicle interior and to prevent external water from flowing into the vehicle along the gap between the side trim 2 and the roof 1, a first sealing strip 4 is provided on the outside of the roof 1 and a second sealing strip 5 is provided on the inside of the side trim 2. The abutment between the first sealing strip 4 and the second sealing strip 5 achieves a seal between the side trim 2 and the roof 1. Because the first sealing strip 4 and the second sealing strip 5 are deformable, as the connecting hinge moves, the first sealing strip 4 and the second sealing strip 5 in contact with the connecting hinge are separated, and the first sealing strip 4 and the second sealing strip 5 not in contact with the connecting hinge abut against each other, ensuring the cleanliness of the environment in the installation groove 701 and preventing dust and water from entering the installation groove 701 and affecting the normal use of the slide rail. In addition, when the tailgate is closed, the tailgate is located at the rear side of the roof 1, and the connecting hinge is completely received in the installation groove 701. The first sealing strip 4 and the second sealing strip 5 abut against each other in the inside-outside direction, thereby sealing the gap between the opposite side trim panel 2 and the roof 1. The utility model not only solves the problem that the roof 1 is an integral structure that is inconvenient to disassemble and assemble the slide rail, but also improves the sealing performance of the vehicle, prevents external noise and water from entering the vehicle, and improves the NVH performance of the entire vehicle.

[0057] 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.
