Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to an edge-coated automotive triangular window assembly. Background Technology
[0002] As an important component of a vehicle's side panel or door, the triangular window not only enhances the overall aesthetics of the vehicle but also plays a crucial role in improving the driver's side visibility, strengthening the vehicle's structure, and assisting with interior lighting and ventilation. With advancements in the automotive industry and increasing consumer demands for a superior driving experience, the design and manufacturing process of triangular windows have received growing attention. Currently, the mainstream process utilizes injection molding with edge wrapping, where a layer of polymer material (such as PVC or TPE) is wrapped around the edge of the glass. This edge wrapping structure serves two purposes: sealing and shock absorption, and securing the triangular window assembly to the vehicle's sheet metal via mounting points. While this process is widely used, problems encountered in actual production and long-term use have become a bottleneck restricting product quality and reliability.
[0003] The existing edge-wrapped triangular window assemblies have insufficient bonding strength between the edge and the glass, relying mainly on the physical and chemical bonding of the adhesive. Under long-term vehicle vibration, drastic temperature changes, and especially in cold regions, the bonding interface is prone to aging and failure, resulting in gaps or even complete separation between the edge and the glass, which seriously affects the sealing performance and produces abnormal noise. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an edge-wrapped automotive triangular window assembly to solve the problem mentioned in the background art of insufficient bonding strength between the edge and the glass, which mainly relies on adhesive bonding and is prone to interface aging and failure under long-term vibration and temperature alternation conditions.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an edge-coated automotive triangular window assembly, comprising a glass body, an edge-coating body fixedly installed on the edge of the glass body, multiple edge micro-grooves and weight-reducing grooves formed on the side of the edge of the glass body, an anti-ultraviolet coating on the outer surface of the glass body, a shatterproof film on the side of the glass body away from the anti-ultraviolet coating, multiple mechanically interlocking protrusions fixedly connected to the inner surface of the edge-coating body, a sealing layer fixedly connected to the inner surface of the edge-coating body, and a heating wire embedded inside the sealing layer.
[0006] Preferably, the outer side of the edging body is fixedly connected with an extended mounting edge.
[0007] Preferably, the outer surface of the mechanical interlocking protrusion is adapted to the inner surface of the edge micro-slot, and the positions of the mechanical interlocking protrusion and the edge micro-slot correspond.
[0008] Preferably, the sealing layer is fitted to the edge of the glass body.
[0009] Preferably, the heating wire is arranged in a serpentine pattern inside the sealing layer.
[0010] Preferably, the shatterproof film is attached to the inner surface of the glass body, and the UV-resistant coating is applied to the outer surface of the glass body. Beneficial effects
[0011] This utility model provides an edge-wrapped rubber-coated automotive triangular window assembly. It has the following beneficial effects: 1. This edge-coated automotive triangular window assembly, by setting a mechanically interlocking protrusion that is interference-fitted with the micro-groove on the edge of the glass body, and supplemented by a tightly fitting flexible sealing layer, fundamentally enhances the mechanical locking force and interface sealing between the edge-coating body and the glass body. It effectively overcomes the risk of delamination caused by vibration and thermal stress, and significantly improves the structural durability, waterproof and dustproof performance and sound insulation effect of the assembly.
[0012] 2. This edge-coated automotive triangular window assembly integrates multiple functions such as defogging, anti-frost, UV blocking, and safety protection by embedding serpentine heating wires in the sealing layer, coating the outer surface of the glass with an anti-UV coating, and attaching an anti-shatter film to the inner surface of the glass. It not only ensures the clarity and safety of the driver's side view, but also slows down the aging of the interior and improves the passive safety level of the passenger compartment. At the same time, through the weight-reducing groove design in the edge area, effective weight reduction is achieved while ensuring structural strength. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] like Figures 1-3 As shown, this utility model provides an edge-coated automotive triangular window assembly, including a glass body 1, an edge-coating body 2 fixedly installed on the edge of the glass body 1, multiple edge micro-grooves 6 and weight-reducing grooves 7 opened on the side of the edge of the glass body 1, an anti-ultraviolet coating 4 provided on the outer surface of the glass body 1, an anti-shatter film 5 provided on the side of the glass body 1 away from the anti-ultraviolet coating 4, multiple mechanically interlocking protrusions 8 fixedly connected to the inner surface of the edge-coating body 2, a sealing layer 9 fixedly connected to the inner surface of the edge-coating body 2, and a heating wire 10 embedded inside the sealing layer 9.
[0017] Specifically, the outer side of the edging body 2 is fixedly connected with an extended mounting edge 3. This extended mounting edge 3 serves as the main connection interface between the assembly and the body sheet metal. Through the mounting holes on it and the fasteners, the triangular window assembly can be quickly and accurately positioned and securely installed on the door frame.
[0018] Specifically, the outer surface of the mechanical interlocking protrusion 8 is adapted to the inner surface of the edge micro-groove 6, and the positions of the mechanical interlocking protrusion 8 and the edge micro-groove 6 correspond. This fit forms an interference fit during the injection molding process, generating a strong mechanical locking force. Its core function is to resist the separation tendency between the edge-wrapping body 2 and the glass body 1 caused by vibration or thermal expansion and contraction, and to ensure the long-term reliability of the combination of the two.
[0019] Specifically, the sealing layer 9 is attached to the edge of the glass body 1. The flexible sealing layer 9 tightly fills the contact interface between the edge of the edging body 2 and the edge of the glass body 1 through its elastic deformation. Its core function is to block the intrusion path of external moisture and dust, while effectively attenuating and absorbing the vibration and noise transmitted to the glass through the vehicle body.
[0020] Specifically, the heating wire 10 is arranged in a serpentine pattern inside the sealing layer 9. This meandering serpentine structure can increase the heating area and ensure uniform heat release. Its function is to continuously and stably heat the edge area of the glass body 1 after power is applied, thereby effectively eliminating the frost and fog accumulated in the area.
[0021] Specifically, the shatterproof film 5 is attached to the inner surface of the glass body 1, and the UV protection coating 4 is coated on the outer surface of the glass body 1. The main function of the shatterproof film 5 is to firmly adhere the glass fragments with its high adhesion and toughness when the glass body 1 is impacted and broken, preventing them from flying and injuring people. The UV protection coating 4 can selectively filter ultraviolet rays in sunlight, and its function is to protect the interior parts of the vehicle from ultraviolet radiation aging and reduce the ultraviolet radiation exposure to the occupants.
[0022] The working principle of the above embodiments: During assembly, the edge-wrapping body 2 is first fixed to the corresponding position on the vehicle door frame via its extended mounting edge 3 on the outside, achieving initial positioning and installation of the assembly. Simultaneously, the serpentine heating wire 10, pre-embedded inside the sealing layer 9, has its electrodes connected to the vehicle's power supply via wires within the edge-wrapping body 2. When needed, it can generate heat to eliminate frost and fog on the inner surface of the glass. During the bonding of the edge-wrapping body 2 and the glass body 1, multiple mechanically interlocking protrusions 8 formed on the inner surface of the edge-wrapping are embedded in pre-drilled edge micro-grooves 6 on the side of the glass body 1 during injection molding, forming an interference fit. This mechanical interlocking structure greatly enhances the bonding force between the edge-wrapping and the glass, effectively preventing them from bonding under vibration or temperature changes. The sealing layer 9, made of flexible material, adheres tightly to the edge of the glass body 1 as a component that directly contacts the glass edge. It not only fills the micro gaps but also forms a reliable sealing system together with the body sheet metal, ensuring the waterproof and sound insulation performance of the window assembly. In addition, the UV-resistant coating 4 applied to the outer surface of the glass body 1 can effectively block ultraviolet rays in sunlight and slow down the aging of the interior. The shatterproof film 5 attached to the inner surface of the glass body 1 can adhere the fragments in the event of accidental glass breakage, preventing them from flying and improving safety. The weight-reducing grooves 7 distributed in the non-critical stress areas of the glass edge achieve a lightweight design of the assembly by removing a small amount of material, which helps to reduce the energy consumption of the whole vehicle.
