Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a vehicle sealing structure and a vehicle. Background Art

[0002] With the development of automobile technology, in order to better adjust the in-vehicle environment to meet the needs of users, more and more functional modules are applied to the glass assembly of the vehicle. Functional modules can change transparency, discoloration, heating or other functions, thereby changing the environmental state of the interior space of the vehicle, which is conducive to improving the user experience. The existing glass assembly is generally a sandwich structure, and the functional layer of the functional module is generally set between two pieces of glass. In addition, the functional layer needs to be connected to the in-vehicle controller to control the functional effect. Therefore, a membrane layer connector is set on the functional layer, and the membrane layer connector is connected to the in-vehicle controller through a wiring harness.

[0003] During the installation process, the existing wiring harness needs to extend from the inside of the car to the glass assembly, and then connect to the membrane joint in the glass assembly. In addition, in order to play a waterproof role, body glue will be injected between the glass assembly and the body. In addition, in order to better ensure the uniformity of the left and right clearances of the glass assembly on the vehicle sheet metal, it is necessary to adjust the fitting gap by moving the glass assembly when the body glue has not solidified. At this time, the wiring harness pasted on the glass assembly will move synchronously with the glass assembly, and the wiring harness will cut the body glue, thereby destroying the structural integrity of the body glue, causing defects such as bubbles and gaps in the body glue. Water can easily leak from the defects in the body glue to the functional layer, causing water to be hidden in the glass assembly for a long time, which in turn leads to the risk of water leakage and cracks in the glass assembly. Summary of the invention

[0013] In a preferred embodiment of the present invention, the functional module includes a dimming module, the functional layer includes a dimming layer disposed in the glass assembly, and the dimming layer can be used to switch between a first transmittance and a second transmittance.

[0014] In a preferred embodiment of the present invention, one end of the circuit membrane is electrically connected to the functional layer, and the other end of the circuit membrane is provided with a wiring harness connector, and the wiring harness connector is used to electrically connect to the in-vehicle controller.

[0015] In a preferred embodiment of the present invention, the circuit film includes a conductor and an insulator for wrapping the conductor.

[0016] In a preferred embodiment of the present invention, the insulator comprises a PI film.

[0017] In a preferred embodiment of the present invention, the glass assembly includes laminated glass and an edging strip wrapping the edge of the laminated glass, the functional layer is arranged in the laminated glass, at least a portion of the circuit film is connected to the inner surface of the laminated glass through the adhesive layer, and one end of the circuit film passes through the gap between the edging strip and the laminated glass and is electrically connected to the functional layer.

[0018] In a preferred embodiment of the present invention, a raised sealing tongue is provided on the edge strip, and the sealing tongue is used to abut against the vehicle body structure.

[0019] In a preferred embodiment of the present invention, the vehicle sealing structure further comprises a waterproof structure for being arranged between the vehicle body structure and the glass assembly, and the waterproof structure is located between the sealant layer and the sealing tongue.

[0020] In a preferred embodiment of the present invention, the waterproof structure includes a first sealing member disposed between the edge strip and the vehicle body structure, and the first sealing member is located between the sealant layer and the sealing tongue.

In addition, in order to play the role of controlling the functional module, it is necessary to use a wiring harness assembly to electrically connect the functional layer and the in-vehicle controller. When installing, the wiring harness assembly needs to extend from the inside of the vehicle to the glass assembly, so that part of the wiring harness assembly is plugged into the gap between the glass assembly and the vehicle body structure. Therefore, in order to better play a waterproof role, a sealant layer is also filled in the gap between the glass assembly and the vehicle body structure to play a sealing role.

[0028] In addition, in order to make the fitting gap between the glass assembly and the vehicle body structure more uniform, the fitting gap will be adjusted by moving the glass assembly before the sealant layer solidifies.

When the glass assembly is moved and adjusted, the uncured sealant layer will flow back and quickly cover the wiring harness assembly at that location along the slope under the action of gravity. The backflow speed is fast, which reduces or eliminates defects such as bubbles and gaps in the sealant layer, thereby improving the sealing quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Implementation Method 1

[0046] Please refer to Figures 1 to 6 As shown, a vehicle sealing structure is provided in an embodiment of the present invention, which includes a glass assembly 200, a functional module 300 and a wiring harness assembly 400 for being arranged on a vehicle body structure 100, and a sealant layer 110 is filled in the gap between the glass assembly 200 and the vehicle body structure 100; the functional module 300 includes a functional layer arranged in the glass assembly 200; the wiring harness assembly 400 is used to electrically connect the functional layer and the in-vehicle controller, at least part of the wiring harness assembly 400 is connected to the inner surface of the glass assembly 200 and is placed in the sealant layer 110, and along the direction away from the glass assembly 200, the end faces of both sides of the wiring harness assembly 400 located in the sealant layer 110 are gradually contracted inward.

[0047] On the whole, when the vehicle sealing structure is in use, the glass assembly 200 is set on the vehicle body structure 100 to form a vehicle sunroof, and by setting a functional module 300 in the glass assembly 200, the functional layer of the functional module 300 can be used to achieve changes in transparency, color change, heating or other functions, thereby changing the environment of the vehicle interior space, which is conducive to improving the user experience.

[0048] Furthermore, in order to play the role of controlling the functional module 300, a wire harness assembly 400 is required to electrically connect the functional layer and the in-vehicle controller. The wire harness assembly 400 needs to be extended from the inside of the vehicle to the glass assembly 200 during installation, so that part of the wire harness assembly 400 is inserted into the gap between the glass assembly 200 and the vehicle body structure 100. Therefore, in order to better play a waterproof role, a sealant layer 110 is also filled in the gap between the glass assembly 200 and the vehicle body structure 100 to play a sealing role.

[0049] Furthermore, in order to make the fitting clearance between the glass assembly 200 and the vehicle body structure 100 more uniform, the fitting clearance will be adjusted by moving the glass assembly 200 before the sealant layer 110 solidifies. At this time, the wiring harness assembly 400 will move with the glass assembly 200, and the wiring harness assembly 400 will cut the unsolidified sealant layer 110, thereby destroying the structural integrity of the sealant layer 110, causing defects such as bubbles and gaps in the sealant layer 110, which in turn cause problems such as water leakage.

[0050] In order to solve the above problems, the present invention gradually shrinks the two side end faces of the wiring harness assembly 400 in the sealant layer 110 inward, so that the wiring harness assembly 400 in the sealant layer 110 is trapezoidal or approximately trapezoidal, so that the two side end faces of the wiring harness assembly 400 form slopes. When the glass assembly 200 is moved and adjusted, the uncured sealant layer 110 will flow back and quickly cover the wiring harness assembly 400 at that location along the slope under the action of gravity. Since the gravity direction of the uncured sealant layer 110 intersects with the slope, the reflux speed of the sealant layer 110 is fast, which helps to reduce or eliminate defects such as bubbles and gaps in the sealant layer 110, thereby improving the sealing quality.

[0051] As a comparative reference, the two side end faces of the existing wiring harness are generally arranged vertically. After the vertical end face cuts the unsolidified sealant layer 110, the gravity direction of the unsolidified sealant layer 110 located on one side of the vertical end face is parallel to the vertical end face, resulting in a slower reflux speed of the sealant layer 110, which is not conducive to reducing or eliminating defects such as bubbles and gaps in the sealant layer 110.

[0052] In an embodiment of the present invention, Figure 6In the illustrated embodiment, the two side end faces of the wiring harness assembly 400 located in the sealant layer 110 are respectively a first end face 401 and a second end face 402, and the inclination angle α of the first end face 401 is 30° to 60° and / or the inclination angle β of the second end face 402 is 30° to 60°.

[0053] Preferably, the inclination angle α of the first end surface 401 is 30° to 60°, and the inclination angle β of the second end surface 402 is 30° to 60°. More preferably, the first end surface 401 and the second end surface 402 are symmetrically arranged.

[0054] The designer can adjust the specific inclination angles of the first end face 401 and the second end face 402 according to the use requirements, and no specific limitation is made here. For example, the inclination angle α of the first end face 401 is 30°, 40°, 50°, 60° or other values. The inclination angle β of the second end face 402 is 30°, 40°, 50°, 60° or other values.

[0055] In an embodiment of the present invention, Figure 4 In the illustrated embodiment, the wiring harness assembly 400 includes a stacked circuit film 410 and an adhesive layer 420. At least a portion of the circuit film 410 is connected to the inner surface of the glass assembly 200 through the adhesive layer 420. The circuit film 410 is used to electrically connect the functional layer and the in-vehicle controller.

[0056] By means of the adhesive layer 420, at least a portion of the circuit membrane 410 can be fixed on the inner surface of the glass assembly 200, thereby improving the structural stability of the circuit membrane 410, avoiding problems such as movement of the circuit membrane 410 during use, and enabling the circuit membrane 410 to be more stably connected to the functional layer and the in-vehicle controller.

[0057] The designer can adjust the specific structure of the adhesive layer according to the use requirements, and no specific limitation is made here. Preferably, the adhesive layer 420 is a double-sided adhesive.

[0058] In an embodiment of the present invention, Figure 4 In the illustrated embodiment, the projection of the circuit film 410 in the sealant layer 110 in the extension direction is arranged in a trapezoidal shape; and / or the projection of the adhesive layer 420 in the sealant layer 110 in the extension direction is arranged in a trapezoidal shape.

[0059] Preferably, the circuit film 410 in the sealant layer 110 is arranged in a trapezoidal shape, and the adhesive layer 420 in the sealant layer 110 is also arranged in a trapezoidal shape.

[0060] By arranging the circuit film 410 and the adhesive layer 420 in the sealant layer 110 in a trapezoidal shape, a roughly trapezoidal wiring harness assembly 400 can be formed. This portion of the wiring harness assembly 400 is in line contact with the sealant layer 110 in the thickness direction, thereby reducing the surface contact between the wiring harness assembly 400 and the sealant layer 110, which is beneficial to the rapid reflow of the sealant layer 110 and the elimination of bubbles.

[0061] Furthermore, by arranging the circuit film 410 and the adhesive layer 420 in a trapezoidal shape, the projection of the circuit film 410 in the thickness direction is located within the adhesive layer 420, so that the adhesive layer 420 has a certain redundancy. Even if the adhesive layer 420 partially shrinks due to heat, the adhesive layer 420 can still be completely fitted with the circuit film 410, avoiding the formation of a leakage gap at the junction of the adhesive layer 420 and the circuit film 410, thereby ensuring the subsequent sealing performance and having a better waterproof effect.

[0062] Designers can adjust the specific processing methods of the circuit film 410 and the adhesive layer 420 according to the use requirements, and no specific restrictions are imposed here. Preferably, the circuit film 410 and the adhesive layer 420 are cut and processed by mechanical means, thereby ensuring the accuracy of the tilt angle.

[0063] The circuit film 410 and the adhesive layer 420 may be cut together after being bonded together. Alternatively, the circuit film 410 and the adhesive layer 420 may be cut separately and then bonded together. Preferably, the circuit film 410 and the adhesive layer 420 may be cut together after being bonded together, which is conducive to simplifying the process and improving the processing efficiency.

[0064] As the thickness of the circuit film 410 increases, a stronger adhesive force is required to ensure the stability of the combination of the circuit film 410 and the glass assembly 200, so it is necessary to increase the thickness of the adhesive layer 420. However, when the adhesive force of the adhesive layer 420 is too strong, the thickness of the adhesive layer 420 is also large, thereby increasing the overall size.

[0065] In order to solve the above technical problems, Figure 4 In the embodiment shown, in the implementation mode of the present invention, the ratio of the thickness dimension L1 of the circuit film 410 to the thickness dimension L2 of the adhesive layer 420 is 1:2 to 1:3.

[0066] By controlling the ratio of the thickness dimension L1 of the circuit membrane 410 to the thickness dimension L2 of the adhesive layer 420, the ratio of the thickness dimension L1 of the circuit membrane 410 to the thickness dimension L2 of the adhesive layer 420 is maintained between 1:2 and 1:3, thereby ensuring that the adhesive force of the adhesive layer 420 can meet the fixing requirements of the circuit membrane 410, while reducing the thickness of the adhesive layer 420 to avoid increasing the overall thickness of the wiring harness assembly 400, thereby ensuring the performance and quality of the product.

[0067] Designers can adjust the specific size of the ratio of the thickness dimension L1 of the circuit film 410 to the thickness dimension L2 of the adhesive layer 420 according to usage requirements, and no specific numerical value is limited here.

[0068] In the embodiment of the present invention, the functional module 300 can be used to realize the change of transparency, color change, heating or other functions, which are not specifically limited here.

[0069] Preferably, the functional module 300 includes a dimming module, and the functional layer includes a dimming layer disposed in the glass assembly 200 , and the dimming layer can be used to switch between a first light transmittance and a second light transmittance.

[0070] The designer can adjust the specific structure of the dimming layer according to the use requirements, and no specific limitation is made here. Preferably, the dimming layer is an electrochromic film layer.

[0071] In an embodiment of the present invention, Figure 1 and Figure 2 In the illustrated embodiment, one end of the circuit membrane 410 is electrically connected to the functional layer, and the other end of the circuit membrane 410 is provided with a wiring harness connector 430, which is used to electrically connect to the in-vehicle controller.

[0072] Specifically, at least a portion of the circuit film 410 is connected to the inner surface of the glass assembly 200 through the adhesive layer 420 , and both ends of the circuit film 410 can be freely designed, thereby improving the wiring flexibility of the two ends of the circuit film 410 .

[0073] Furthermore, by providing a wiring harness connector 430 at the other end of the circuit film 410, the wiring harness connector 430 can be quickly connected to the extension circuit of the in-vehicle controller, thereby improving wiring efficiency. The designer can adjust the specific structure of the wiring harness connector 430 according to the use requirements, and no specific restrictions are made here.

[0074] In an embodiment of the present invention, Figure 5 In the illustrated embodiment, the circuit film 410 includes a conductor 411 and an insulator 412 for wrapping the conductor 411 .

[0075] The designer can adjust the specific material and structure of the insulator 412 according to the use requirements, and no specific limitation is made here. Preferably, the insulator 412 includes a PI film. The PI film is a polyimide film, which has good mechanical properties, thermal stability and electrical insulation.

[0076] Furthermore, the designer may adjust the specific structure and material of the conductor 411 according to the use requirements, and no specific limitation is imposed here. Preferably, the conductor 411 is a conductive copper foil.

[0077] In an embodiment of the present invention, Figure 3 In the illustrated embodiment, the glass assembly 200 includes a laminated glass 210 and an edge strip 220 wrapping the edge of the laminated glass 210, the functional layer is disposed in the laminated glass 210, at least a portion of the circuit film 410 is connected to the inner surface of the laminated glass 210 through the adhesive layer 420, and one end of the circuit film 410 passes through the gap between the edge strip 220 and the laminated glass 210 and is electrically connected to the functional layer.

[0078] By providing an edge strip 220 at the edge of the laminated glass 210 , the edge strip 220 can not only protect the laminated glass 210 , but also help improve the aesthetics of the glass assembly 200 and enhance the sealing performance of the edge of the glass assembly 200 .

[0079] In an embodiment of the present invention, Figure 3 In the illustrated embodiment, a raised sealing tongue 221 is provided on the edge strip 220, and the sealing tongue 221 is used to abut against the vehicle body structure 100. Designers can adjust the specific shape and structure of the sealing tongue 221 according to usage requirements, and no specific limitation is made here.

[0080] By making the sealing tongue 221 abut against the vehicle body structure 100 , the sealing tongue 221 enhances the connection strength between the glass assembly 200 and the vehicle body structure 100 , thereby improving the stability and durability of the overall structure.

[0081] Furthermore, the sealing tongue 221 can play a sealing role to prevent water from entering the gap between the glass assembly 200 and the vehicle body structure 100. Furthermore, the sealing tongue 221 also eliminates the gap between the glass assembly 200 and the vehicle body structure 100, which helps to improve the aesthetics of the vehicle.

[0082] In an embodiment of the present invention, the vehicle sealing structure further includes a waterproof structure 500 disposed between the vehicle body structure 100 and the glass assembly 200 . The waterproof structure 500 is located between the sealant layer 110 and the sealing tongue 221 .

[0083] By providing the waterproof structure 500 between the vehicle body structure 100 and the glass assembly 200 , it helps to further enhance the waterproof performance of the vehicle and prevent water from leaking into the vehicle.

[0084] In an embodiment of the present invention, Figure 3 In the illustrated embodiment, the waterproof structure 500 includes a first sealing member 510 disposed between the edge strip 220 and the vehicle body structure 100 . The first sealing member 510 is located between the sealant layer 110 and the sealing tongue 221 .

[0085] Specifically, the first seal 510 is bonded and fixed to the edging strip 220, thereby ensuring that the first seal 510 does not fall off during the installation process, and the first seal 510 can also fit tightly with the vehicle body structure 100 after installation, thereby playing a sealing role between the edging strip 220 and the vehicle body structure 100 to prevent water from entering the interior of the vehicle.

[0086] The designer may adjust the shape, structure and material of the first seal 510 according to the use requirements, and no specific limitation is imposed here. Preferably, the first seal 510 includes a sealing block disposed along the circumference of the glass assembly 200 between the edge strip 220 and the vehicle body structure 100. More preferably, the first seal 510 is a sealing foam.

[0087] By arranging sealing foam between the edging strip 220 and the vehicle body structure 100, the sealing foam can be tightly combined between the edging strip 220 and the vehicle body structure 100, thereby having a certain blocking effect on water, dust and noise. At the same time, the sealing foam can also provide a certain buffering protection and heat preservation effect.

[0088] Further, such as Figure 3 In the illustrated embodiment, the waterproof structure 500 further includes a second sealing member 520 disposed between the edge strip 220 and the vehicle body structure 100 . The second sealing member 520 is located between the first sealing member 510 and the sealing tongue 221 .

[0089] The designer may adjust the shape, structure and material of the second seal 520 according to the use requirements, and no specific limitation is imposed here. Preferably, the second seal 520 comprises a sealing block disposed along the circumference of the glass assembly 200 between the edge strip 220 and the vehicle body structure 100 .

[0090] In the embodiment of the present invention, the second sealing member 520 is a water-absorbing foam. The designer can determine the specific material of the water-absorbing foam according to the use requirements, and no specific limitation is made here. For example, the water-absorbing foam is EPDM foam rubber, polyurethane foam, acrylic foam or other materials.

[0091] Preferably, the water-absorbing foam is EPDM foam rubber, which is a foam material made of ethylene propylene diene monomer (EPDM). By providing the water-absorbing foam composed of EPDM foam rubber, the water-absorbing foam can absorb moisture in a short time, and increase its own density after being saturated with water, thereby increasing its water barrier performance. In addition, the water-absorbing foam can be saturated after absorbing a small amount of water, so that the gap can be quickly sealed to discharge excess water. At the same time, the water-absorbing foam can evaporate water in a short time. This characteristic enables the EPDM foam rubber to not only effectively absorb the infiltrated moisture in a short time, but also quickly restore its original waterproof performance, ensuring a long-term waterproof effect.

By covering the glass assembly 200 on the window structure, a vehicle sunroof can be formed.
