Description

Technical Field

[0001] This utility model belongs to the field of automotive body accessory technology, and more specifically, it relates to a rear blind window for automobiles. Background Technology

[0002] SUVs, MPVs, station wagons, and some crossover models are often used for medium- to long-distance travel or temporary rest stops due to their spacious interiors. Therefore, the privacy and comfort needs of rear passengers are increasingly prominent. Currently, most car rear side windows use transparent glass with dark sunshades for privacy protection, but this approach has the following shortcomings: 1. Incomplete privacy protection: Sunshades are movable parts, easily damaged, and have physical gaps, failing to achieve complete privacy isolation; 2. When the sunshade is retracted, the window is transparent, failing to provide a personalized appearance; 3. Traditional window installations mainly rely on a single or double rubber sealing strip for compression and sealing. With long-term use, vehicle body movement, or harsh road conditions, the sealing performance gradually decreases, leading to increased wind noise, water leakage, and dust ingress; furthermore, limited by glass molding processes and the arrangement of sealing strips, window shapes are mostly regular flat surfaces or simple curves, making it difficult to achieve more complex and sculptural three-dimensional designs.

[0003] Based on this, blind window structures have emerged on the market. For example, patent publication number CN104842753A discloses a vehicle body blind window structure and a cargo vehicle. The blind window panel is no longer a flat plate, but instead has a stop positioning structure between it and the window. The blind window panel is installed on the inside, with the central body protruding outwards from the window. The stop positioning structure is secured to the edge of the window, while the outer perimeter is welded to the inner wall of the side panel. The stop positioning structure eliminates the need for manual support and facilitates welding operations.

[0004] However, the above-mentioned blind window structure still has the following shortcomings: 1. The blind window panel is installed on the inside. Once it is damaged or leaks, the interior trim parts of the vehicle must be removed for replacement, which is cumbersome and costly; 2. The weld sealant is only applied to the surface of the stop step or the outer perimeter. The stop step is an inclined surface, which makes it easy for the sealant layer to flow during application, resulting in insufficient local sealing thickness and poor sealing effect; 3. The inner welding area lacks a waterproof structure, which makes it easy for water to enter the gap between the side panel and the blind window panel, corroding the blind window reinforcement plate and the side panel. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a rear blind window for automobiles. When installed, the removable sealing strip at the edge of the blind window forms the first seal, blocking external airflow and rainwater; the sealing adhesive layer between the blind window and the vehicle body forms the second waterproof and soundproof barrier; at the same time, the polyurethane sealing adhesive layer between the inner and outer panels seals the gap between the panels, preventing water vapor and dust from entering. The triple seal works together to achieve excellent waterproof, dustproof and soundproof effects, while avoiding corrosion of components caused by the intrusion of corrosive media from outside the vehicle.

[0006] The aforementioned rear blind window for automobiles includes an outer side window panel, an inner side window panel inside the outer side window panel, a removable sealing strip sealed to the edge of the outer side window panel, at least one mounting groove recessed into one side of the outer side window panel on the inner side window panel, a buffer sponge block between the outer side of the mounting groove and the outer side window panel, and a sealing layer one on the periphery of the mounting groove and the periphery of the inner side window panel, respectively, and the inner side window panel is glued and fixed to the outer side window panel by the sealing layer one.

[0007] Preferably, a plurality of mounting seats and an outer panel limiting block are fixedly connected to the inner side wall of the outer side window panel. The mounting seats are provided with threaded holes, the inner side window panel is provided with mounting holes corresponding to the threaded holes, and a limiting seat corresponding to the position of the outer panel limiting block is fixed on the inner side window panel. The limiting seat is provided with a limiting hole for engaging the outer panel limiting block.

[0008] Preferably, there are two outer panel limiting blocks, which are respectively located at the two ends of the diagonal line of the outer panel near the side window.

[0009] Preferably, the mounting groove has a protrusion around its periphery, the protrusion protruding away from the side window outer panel, the mounting hole is provided on the protrusion, and the protrusion is provided with a detachable decorative aluminum plate, the side window outer panel, the side window inner panel and the decorative aluminum plate are fixedly connected by fasteners.

[0010] Preferably, the protrusion is provided with a forming groove around its periphery, the forming groove being in the same direction as the recess of the mounting groove, and the forming groove having an assembly hole for fixed connection with the vehicle body.

[0011] Preferably, an inner panel limiting block one is fixed at the upper end of the bottom surface of the molding groove on the side away from the outer panel of the side window, and an inner panel limiting block two for supporting and limiting the molding groove is fixed at the lower part of the molding groove; a sealing adhesive layer one for bonding and fixing the molding groove to the outer panel of the side window is provided on the side of the molding groove near the outer panel of the side window.

[0012] Preferably, a forming protrusion is provided between the forming groove and the edge of the inner panel of the side window, the forming protrusion is in the same direction as the protrusion of the protrusion, and the edge of the inner panel of the side window extends to the outer panel of the side window to form a folded edge structure.

[0013] Preferably, the molded protrusion is provided with a second sealing adhesive layer for bonding and fixing to the car body.

[0014] Preferably, the protrusion, the shaped protrusion, and the recessed surface of the inner edge of the side window are each fixedly connected with a plurality of reinforcing ribs.

[0015] Preferably, the outer surface of the side window outer panel is provided with an integrally formed relief design.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. The inner and outer panels of the blind window are pre-positioned by interlocking the outer panel limiting blocks and limiting seats arranged diagonally. The blind window as a whole is precisely connected to the vehicle body through upper and lower double limiting blocks. The alignment accuracy of the mounting holes and sealing positions can be guaranteed without complicated tooling, which greatly reduces the error of manual positioning, lowers the operation threshold of assembly personnel, and facilitates loading and unloading.

[0017] 2. During installation, the blind window and the car body employ a double seal using both a sealing strip and a polyurethane sealant layer. The removable sealing strip along the edge of the blind window forms the first layer of seal, blocking external airflow and rainwater. The sealant layer between the blind window and the car body forms the second layer of waterproof and soundproof barrier. Simultaneously, the polyurethane sealant layer between the inner and outer panels seals the gaps between the panels, preventing moisture and dust intrusion. This triple seal works synergistically to achieve excellent waterproof, dustproof, and soundproof performance, while also preventing corrosion of components caused by external corrosive media.

[0018] 3. A removable decorative aluminum panel is added to the inner panel of the side window. The decorative aluminum panel can cover the mounting groove to ensure a clean visual appearance inside the vehicle. After removing the decorative aluminum panel, the mounting groove of the inner panel of the side window can be equipped with embedded display screens, driving sensors and other functional components as needed. This does not take up interior space and can expand the entertainment and monitoring functions of the blind window, adapting to the functional customization needs of different models and taking into account both practicality and aesthetics.

[0019] 4. A buffer sponge block is added to the outside of the mounting groove to fill the gap between the inner and outer panels. This can absorb the vibration caused by vehicle bumps, eliminate the abnormal noise of panel collisions, and also help block the transmission of heat and noise from outside the vehicle. Combined with the multi-layer sealing structure, it greatly improves the quietness and temperature control comfort inside the vehicle. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figures 1 to 8 As shown, a rear blind window for automobiles includes a side window outer panel 1. In this embodiment, the side window outer panel 1 is made of PC+ABS (polycarbonate + acrylonitrile-butadiene-styrene) material, which can meet the structural strength requirements of the rear blind window outer panel of automobiles, resisting external impacts such as gravel and scratches during driving, and can also adapt to complex mold forming processes to realize irregular structures such as relief shapes; at the same time, the material has good high and low temperature resistance, can adapt to the complex outdoor conditions of the whole vehicle, and is not easy to deform and crack. During manufacturing, the surface of the side window outer panel 1 is painted, which can form a protective film on the material surface, delaying material aging and yellowing, and extending service life.

[0024] The side window outer panel 1 features an integrally formed embossed design 103. This embossed design 103 optimizes the visual effect of the blind window's outer surface, enhancing the overall aesthetics of the vehicle body. Simultaneously, it strengthens the surface rigidity of the side window outer panel 1, reducing dents and deformations caused by external impacts, thus serving both decorative and structural reinforcement functions. In this embodiment, the outer side of the side window outer panel 1 adopts a curved design to match the streamlined shape of the vehicle body side, effectively reducing wind resistance.

[0025] The side window outer panel 1 is equipped with a side window inner panel 3. The side window inner panel 3 is made of ASA (acrylonitrile-styrene-acrylate) material and has a leather texture on the surface. While ensuring the structural stability of the side window inner panel 3, the leather texture can be consistent with the texture of other interior parts in the vehicle, thus improving the overall coordination of the interior.

[0026] A removable sealing strip 2 is sealed at the edge of the outer side window panel 1. The sealing strip 2 fills the gap between the outer side window panel 1 and the mounting position on the vehicle body 5, achieving the first seal at the edge of the blind window and isolating it from rainwater, airflow, and noise. Simultaneously, the removable design facilitates replacement and maintenance after the sealing strip 2 ages, and also adapts to compensation adjustments for different vehicle body mounting tolerances. The inner side window panel 3 is injection-molded with at least one mounting groove 301 recessed towards one side of the outer side window panel 1. On one hand, the recessed shape of the mounting groove 301 enhances the local structural strength of the inner side window panel 3 and disperses external impact forces; on the other hand, the mounting groove 301 provides installation space for specific functional components, and the recessed structure reduces the space occupied inside the vehicle. In use, an embedded display screen or sensor can be installed within the mounting groove 301.

[0027] A buffer sponge block 309 is attached between the outer side of the mounting groove 301 and the outer side window panel 1. The buffer sponge block 309 can fill the gap between the mounting groove 301 and the outer side window panel 1, play a role in buffering and damping, and offset the collision noise between the two when the vehicle is bumpy. At the same time, it can also help block the transmission of heat and noise from outside the vehicle, and improve the driving comfort.

[0028] A sealant layer 308 is provided around the mounting groove 301 and around the inner side window panel 3. The sealant layer 308 is polyurethane sealant. The inner side window panel 3 is bonded and fixed to the outer side window panel 1 via the sealant layer 308. During operation, a polyurethane primer is first applied to the corresponding positions on the inner side window panel 3 and the outer side window panel 1, followed by the application of polyurethane sealant to bond them together. The sealant layer 308 serves two purposes: firstly, it ensures a strong bond between the inner side window panel 3 and the outer side window panel 1, guaranteeing the reliability of the double-layer structure; secondly, it forms a sealing barrier at the bonding point, preventing moisture and dust from entering through the gap between the double layers, while also enhancing the waterproof and sound insulation performance of the connection area.

[0029] Multiple mounting seats 101 and outer panel limiting blocks 102 are fixedly connected to the inner wall of the outer side window panel 1. The mounting seats 101 have threaded holes, providing threaded connection points and a basis for the mechanical fastening of the inner side window panel 3 and the outer side window panel 1. The outer panel limiting blocks 102 are used to pre-position the inner side window panel 3, ensuring the assembly position accuracy of the inner side window panel 3 and the outer side window panel 1 and preventing assembly misalignment. The inner side window panel 3 has mounting holes 304 corresponding to the threaded holes. The threaded holes and mounting holes 304 cooperate to achieve mechanical locking of the inner side window panel 3 and the outer side window panel 1 through fasteners, forming a composite connection structure of "adhesive bonding + mechanical fastening" with the sealing adhesive layer 308, significantly improving the firmness and durability of the double-layer panel connection. A limiting seat 307 corresponding to the position of the outer panel limiting block 102 is fixed on the inner panel of the side window. The limiting seat 307 has a limiting hole for engaging with the outer panel limiting block 102. The engaging of the limiting hole with the outer panel limiting block 102 can precisely limit the assembly position of the inner panel of the side window 3 relative to the outer panel of the side window 1, prevent horizontal or circumferential offset during assembly, ensure the alignment accuracy of the corresponding holes and sealing positions of the double-layer panels, and reduce the assembly difficulty.

[0030] In this embodiment, there are two outer panel limiting blocks 102, which are respectively located at the two ends of the diagonal of the outer panel 1 of the side window. The two outer panel limiting blocks 102 utilize the stability of diagonal positioning to maximize the overall flatness of the inner panel 3 of the side window assembly and avoid warping or displacement of the panel surface caused by local positioning.

[0031] The mounting groove 301 is provided with a protrusion 310 around its periphery. The protrusion 310 protrudes away from the side window outer panel 1, that is, the protrusion 310 protrudes towards the inside of the vehicle. This can raise the mounting plane of the mounting hole 304 and the decorative aluminum plate 4, and avoid interference with the components in the mounting groove 301 when installing fasteners. At the same time, the protruding shape can enhance the local bending and torsional strength of the side window inner panel 3.

[0032] The mounting hole 304 is located on the protrusion 310, and a detachable decorative aluminum plate 4 is provided on the protrusion 310. The outer side window panel 1, the inner side window panel 3, and the decorative aluminum plate 4 are fixedly connected by fasteners 401. By placing the mounting hole 304 on the protrusion 310, the structural strength of the protrusion can bear the locking stress of the fastener, preventing the inner side window panel 3 from being dented or deformed due to the locking force. The detachable decorative aluminum plate 4 can cover the mounting groove 301, optimizing the interior visual effect when no specific functional components are installed.

[0033] The protrusion 310 has a forming groove 311 around its periphery. The forming groove 311 is aligned with the recessed direction of the mounting groove 301. The forming groove 311 has mounting holes 305 for fixed connection with the vehicle body. The forming groove 311 can further optimize the stress distribution on the side window inner panel 3 and enhance the overall rigidity of the inner panel. At the same time, it provides independent mounting areas for components such as the mounting holes 305 and the inner panel limiting blocks, avoiding interference between the mounting points of various components.

[0034] An inner panel limiting block 306 is fixed to the upper end of the bottom surface of the molding groove 311 on the side away from the outer side window panel 1, and an inner panel limiting block 303 is fixed to the lower part of the molding groove 311 for limiting its position against the vehicle body. The inner panel limiting blocks 306 and 303 form limiting supports with the vehicle body mounting position at the upper and lower parts, respectively, to achieve precise pre-positioning of the blind window with the vehicle body, ensuring the alignment accuracy of the mounting hole 305 and the connecting hole of the vehicle body 5. At the same time, the upper and lower limiting can distribute the gravitational load of the blind window and avoid stress concentration at a single connection point. A sealing layer 308 is provided on the side of the molding groove 311 near the outer side window panel 1 for bonding and fixing with the outer side window panel 1. The sealing layer 308 in this area can fill the gap between the molding groove 311 and the outer side window panel 1, further strengthening the sealing and connection between the two layers and preventing moisture from entering the interior of the two layers from the molding groove area.

[0035] A forming protrusion 312 is provided between the forming groove 311 and the edge of the inner side window panel 3. The forming protrusion 312 is aligned with the protrusion direction of the protrusion 310, and the edge of the integrally formed inner side window panel 3 extends towards the outer side window panel 1 to form a folded edge structure. The forming protrusion 312 can enhance the structural strength of the edge area of ​​the inner side window panel 3 and improve the deformation resistance of the inner panel. The outer edge of the inner side window panel 3 extends outward to form edge protection, preventing sharp edges from scratching the sealant layer or body parts, while increasing the contact area with the outer side window panel 1 and improving the connection sealing performance.

[0036] The molded protrusion 312 is provided with a second sealant layer 302 for bonding and fixing with the car body. The second sealant layer 302 is the same as the first sealant layer 308, and will not be described again. The second sealant layer 302 helps to enhance the connection between the blind window and the car body 5, and forms a second waterproof and soundproof barrier in the contact gap between the blind window and the car body 5, blocking rainwater and noise from outside the vehicle.

[0037] Multiple reinforcing ribs are fixedly connected to the protrusion 310, the shaped protrusion 312 and the recessed surface of the edge of the inner panel 3 of the side window. The reinforcing ribs can further enhance the structural strength and rigidity of various local irregular structures, such as the protrusion, the shaped protrusion and the edge recess, disperse the vibration stress generated during vehicle driving, prevent structural deformation and cracking, and extend the service life of the blind window.

[0038] like Figures 9 to 11As shown, during assembly, the present invention first applies a primer to the overlapping area of ​​the molded protrusion 312 on the inner side of the side window and the side opening of the car body 5 using a robot. This enhances the surface activity of the substrate. The primer is 18-22mm wide. Then, polyurethane sealant 302 is applied, with the same width as the primer. Next, the limiting holes of the limiting seat 307 on the inner side window panel 3 are aligned with the limiting blocks 102 at the diagonal ends of the inner side of the outer side window panel 1 and engaged. Utilizing the stability of diagonal positioning, the relative position of the inner side window panel 3 and the outer side window panel 1 is quickly defined, preventing horizontal offset or warping of the inner side window panel 3. This ensures precise alignment of the mounting hole 304 with the threaded hole of the mounting seat 101, laying the foundation for subsequent mechanical fastening.

[0039] After the inner and outer panels are pre-positioned, the inner panel limiting block 306 and the inner panel limiting block 303 on the forming groove 311 of the inner side window 3 are respectively abutted against the corresponding installation positions on the car body 5. The blind window is initially fixed by the upper and lower limiting points, ensuring the alignment accuracy of the mounting hole 305 with the car body connection hole, while dispersing the gravity load of the blind window and preventing stress concentration at a single connection point. Then, the side window is precisely positioned and pressed onto the side opening of the car body. The pressure is maintained by the clamp to make the polyurethane sealing layer tightly adhere to the car body 5, and the sealing layer gradually cures to form a strong main seal bond. Then, the fastener 104 is passed through the positioning hole and mounting hole 305 of the car body 5 to mechanically fix the blind window to the car body 5. Finally, the sealing strip 2 is snapped into the outer edge of the outer side window 1 to complete the final assembly.

[0040] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
