Embodiment One

Referring to FIG. 2 and FIG. 3, an encapsulation component according to an embodiment of the present disclosure is schematically illustrated.

In some embodiments, the encapsulation component includes:

An encapsulation 20 surrounding edges of a body 10. The body 10 is a quarter window glass of a vehicle. The encapsulation 20 is an injection molded encapsulation, which is a one-piece component and is formed on the quarter window glass of a vehicle by an injection molding method. Specifically, the material of the encapsulation 20 is polyvinyl chloride (PVC) . A through slot 21 is disposed on the encapsulation 20. In FIG. 2, a metal plate 23 is embedded in the encapsulation 20. The metal plate 23 is applied to enhance the structural strength of the encapsulation 20, which is put into a mold cavity together with the glass 10 during the injection molding process, so that the injection molded encapsulation 20 wraps the metal sheet 23. The encapsulation 20 further includes a notch 24, as shown clearly in FIG. 3, the width of the notch 23 along a direction of x axis is nearly equal to the width of a fastener 31. As a result, when an end of the fastener 31 is bended to be embedded in the notch 24, the side surfaces of the fastener 31 contact with the side surfaces of the notch 24, which limits a bright strip 30 in the x direction.

The through slot 21 on the encapsulation 20. The through slot 21 works together with the fastener 31 on the bright strip 30 to fix the bright strip 30 on the encapsulation 20. Alternatively, a cross section of the through slot 21 parallel to the plane of the body 10 is rectangle-shaped, square-shaped, or oval-shaped. In some embodiments, a cross section of the through slot 21 is rectangle-shaped.

The bright strip 30 disposed on an outward side of the encapsulation 20 (namely, the side towards the exterior of the vehicle when the vehicle window is installed) . The bright strip 30 is connected to the encapsulation 20 through a joining between the fastener 31 and the through slot 21. The bright strip 30 may improve the appearance of the encapsulation 20. In some embodiments, the bright strip 30 is made of metallic materials.

The fastener 31 connected to the bright strip 30. The fastener 31 passes the through slot 21 to fix the bright strip 30 on the encapsulation 20. In some embodiments, the fastener 31 is connected to the bright strip 30 in a welding or a riveting way. The fastener 31 is a flat and straight metal sheet before installed, and then the metal sheet is installed to the bright strip 30. After the bright strip 30 is installed, the other end of the fastener 31 far away from the bright strip 30 bends towards the other side of the through slot 21 to be locked by the encapsulation 20 and thus the bright strip 30 is fixed. As shown in FIG. 2, a gap exists between the fastener 31 and the through slot 21 in the side towards y direction (namely, the side opposite to the bending direction of the fastener 31) .

A cover plate 22 connected to the encapsulation 20. The cover plate 22 is used to cover the gap between the through slot 21 and the fastener 31. In some embodiments, the cover plate 22 is a separate flexible component, and one end of the cover plate 22 is connected to the encapsulation 20 on one side of the through slot 21. Specifically, an adhesive layer is disposed on a surface of the cover plate 22, and the cover plate 22 is connected to the encapsulation 20 on one side of the through slot 21 by virtue of the adhesive layer. The other end of the cover plate 22 is an extension end. In some embodiments, the extension end is a free end and extends towards the other side of the through slot 21, covering the light penetrating area between the fastener 31 and the through slot 21. When the bright strip 30 is installed, the cover plate 22 is in contact with the fastener 31, covering the gap between the through slot 21 and the fastener 31.

In some embodiments, a notch 24 is not included in the encapsulation 20. The other end of the fastener 31 is bended on the surface of the encapsulation 20 to fasten the bright strip 30.

In some embodiments, a metal sheet is not included in the encapsulation 20. Only the glass 10 is put into the mold cavity in the injection molding process, as a result, the injection molded encapsulation 20 wraps edges of the body 10.

In some embodiments, the extension end is attached to the fastener 31 through an adhesive layer.

Further, in other embodiments, the width of the cover plate 22 along the x direction is slightly smaller than the width of the through slot 21. In some embodiments, the length of the cover plate 22 along the y direction is greater than the length of the through slot 21, the width of the cover plate 22 along the x direction is greater than the width of the through slot 21, the adhesive layer covers one end of the cover plate 22 opposite to the encapsulation 20, and the cover plate 22 is attached to the encapsulation 20 surrounding the through slot 21 and the fastener 31 through the adhesive layer, fully covering the opening of the through slot 21.

Embodiment Two

The similarity between the second embodiment and the first embodiment is not described in detail herein. The difference between them lies in that the through slot on each encapsulation corresponds to two fasteners, including a first fastener and a second fastener. The two fasteners are compactly arranged in series to form a straight line. Both the two fasteners go through the through slot to fasten the bright strip on the encapsulation. The bending way and bending direction of the first fastener is the same as the fastener 31 in the first embodiment, the bending way of the second fastener is the same as the fastener 31 in the first embodiment, while the bending direction of the second fastener is opposite to the fastener 31 in the first embodiment. In some embodiments, the light penetrating area locates in a gap between the first fastener and the through slot, and the cover plate covers the gap between the first fastener and the through slot.

In some embodiments, the sum of the width of the first fastener and the width of the second fastener is less than the width of the through slot, and the light penetrating area locates at the two ends of the two fasteners. The cover plate is connected to the encapsulation surrounding the through slot and the two fasteners through the adhesive layers, fully covering the opening of the through slot.

Embodiment Three

Referring to FIG. 4, a cross-sectional view of an encapsulation component according to another embodiment of the present disclosure is illustrated. The similarity between the third embodiment and the first embodiment is not described in detail herein.

The difference between the third embodiment and the first embodiment lies in: that the fastener 310 and the encapsulation 20 are a one-piece component. For instance, the cover plate 220 and the encapsulation 20 are formed in the same injection molding process, or through a secondary injection molding.

In some embodiments, a cross section of the cover plate 220 perpendicular to the plane of the glass 10 is trapezoid-shaped. The extension end of the cover plate 220 extending towards the other side of the through slot 21 is a free end, and a thickness of the free end is 0.3 mm to 2 mm； in some embodiment, the thickness of the free end is 0.5 mm to 1 mm. When the thickness is greater than 0.5 mm, it’s beneficial to reduce the cost of the injection molding, because there is no need to apply the high precision mold and high fluidity materials with high cost. When the thickness is less than 1 mm, the fastener 310 is not likely to get damaged in the mounting process, since the cover plate 220 may possibly get deformation. The distance between the extension end of the cover plate 220 extending towards the other side of the through slot 21 and the other side of the through slot 21 is 0.1 mm to 0.5 mm. Specifically, along the y direction in FIG. 5, the distance between the extension end of the cover plate 220 and the side wall of the other side of the through slot 21 is 0.1 mm to 0.5 mm, which makes convenience for the fastener 310 to overcome the resistance from the cover plate 220 to go through the through slot 21, without affecting the shading effect of the cover plate 220.

Embodiment Four

The similarity between the forth embodiment and the third embodiment won’t be discussed in detail herein. The difference between the forth embodiment and the third embodiment lies in: that a cross section of the cover plate perpendicular to the plane of the body 10 is rectangle-shaped, a thickness of the cover plate is 0.3 mm to 2 mm； in some embodiment, the thickness of the cover plate is 0.5 mm to 1 mm. When the thickness is greater than 0.5 mm, it’s beneficial to reduce the cost of the injection molding. When the thickness is less than 1 mm, the fastener is not likely to get damaged in the mounting process, since the cover plate is liable to get deformation.

Embodiment Five

The similarity between the fifth embodiment and the third embodiment won’t be discussed in detail herein. The difference between the fifth embodiment and the third embodiment lies in that the cover plate and the encapsulation are a one-piece component by injection molding. A cross section of the cover plate perpendicular to the plane of the glass 10 is triangle-shaped. One end of the cover plate connected to the encapsulation locates at the bottom side of the triangle, with the thickness of 0.5 mm to 1 mm. The other end of the cover plate is the extension end, locating at the vertex of the triangle. The thickness of the cover plate decreases gradually in a direction along which the cover plate extends toward the other side of the through slot.

Further, in some embodiments, the thickness of the extension end is obviously less than 0.5 mm, such as 0.1 mm, and is connected to the encapsulation on the other side of the through slot. Since the thickness of the extension end of the cover plate is quite small and the extension end locates at the vertex of the triangle-shaped cross section, the connection between the extension end of the cover plate and the encapsulation is actually a weak line connection, which can be separated easily. In the mounting process of the bright strip, the fastener is inserted into the through slot and pushed forward, after the top of the fastener contacts with the cover plate and if the fastener keeps moving forward, the fastener separates the cover plate, then the fastener is bended to fasten the bright strip and the encapsulation. The cover plate keeps in touch with the fastener due to its elasticity, and covers the light penetrating area between the fastener and the through slot.

It should be noted that, the glass body in the present disclosure is only an exemplary embodiment, instead of limiting the material of the body. The body can also be other appropriate materials, for example, transparent plastic.

It should be also noted that, the above embodiments disclosed in the present disclosure are only for the purpose of describing but not to be limitation of the utility model. It should be understood by those skilled in the art that various changes may be made without departing from the spirit or scope of the disclosure. These changes are considered to fall within the protection scope of the utility model and the attached claims herein. The scope of the utility model is determined by the attached claims. Furthermore, any marks in the drawing should not be interpreted as limitations to the claims. The use of verb “include” and any form of its deformation doesn’t exclude the existence of other elements or procedures except the elements and procedures listed in the claims. The indefinite article “a” or “one” before the elements and procedures doesn’t exclude the existence of multiple similar elements or procedures.
