The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The present invention will be further explained with reference to the accompanying drawings.

As shown in FIGS. 1-3, a glass assembly 1, including glass 10, the portion of moulding plastics and exterior gadget 40, the portion of moulding plastics is fixed mutually with glass 10, exterior gadget 40 with the portion of moulding plastics is fixed, glass 10, the portion of moulding plastics and exterior gadget 40 are injection moulding as an organic whole, and the runner of moulding plastics is located the lower part of the portion of moulding plastics, glass 10 is equipped with at least one through-hole 101, and the material of moulding plastics forms the portion of moulding plastics through-hole 101, glass 10 the edge with there is the clearance between the portion of moulding plastics, the portion of moulding plastics is including consecutive first portion 20 and second portion 30, the cladding of first portion 20 is fixed the upper surface 102 of glass 10, exterior gadget 40 is fixed the upper surface of first portion 20, second portion 30 is located in the through-hole 101. The exterior trim 40 may be a decorative trim such as a bright trim. The glass 10 is provided with a plurality of through holes 101 (both drilled holes and reserved holes), when the integral injection molding is carried out, the glass 10 and the exterior trimming part 40 are firstly fixed in a mold, the injection molding material at the gate can directly flow from one surface of the glass 10 to the other surface through the through holes 101, the first part 20 of the injection molding part is fixed on the upper surface 102 of the glass 10 in a covering mode through cooling solidification, and the exterior trimming part 40 is fixed on the upper surface of the first part 20. As shown in FIG. 2, from the overall appearance of the glass assembly 1, the exterior trimming member 40 is far from the edge of the glass 10 and is near the center of the glass surface, so that the exterior trimming member 40 is suspended on the upper surface 102 of the glass.

When the through holes 101 in the glass 10 and the exterior trimming part 40 are arranged in a staggered manner, in the integral injection molding process, the flowing filling of the injection molding material can impact the exterior trimming part, so that the position of the exterior trimming part 40 is deviated, the appearance quality of the injection molded glass assembly 1 is poor, and the yield is affected. To alleviate this problem, it is preferable that the through hole 101 be disposed opposite to the lower surface of the exterior trim 40.

When the injection-molded part only comprises the first part 20 and the second part 30 which are connected, the exterior trimming part 40 has the appearance effect of suspending on the upper surface 102 of the glass when the exterior trimming part 40 is fixed on the upper surface of the first part 20, and therefore the lower surface of the second part 30 and the lower surface 103 of the glass 10 can be flush with each other, as shown in fig. 3.

As shown in fig. 4, the injection molding part further includes a third portion 50, the third portion 50 is connected to the second portion 30, the third portion 50 is fixedly wrapped on the lower surface 103 of the glass 10, and the through hole 101 is completely wrapped in the injection molding part. When the third portion 50 is wrapped and fixed on the lower surface 103 of the glass 10, both the upper portion and the lower portion of the injection molding part can be wrapped and fixed on the glass 10, so that the injection molding part is firmly fixed on the glass 10, and a relatively firm combination is formed.

In order to achieve the purpose that the glass assembly 1 is stably fixed on the vehicle body for a long time, a functional member may be disposed on the lower surface of the third portion 50, and the functional member may be a stud, a bolt, or other members having a connection fixing function. As shown in fig. 5, the lower surface of the third portion 50 is provided with a post 60. Since the movement of the functional member can drive the exterior trimming part 40 to deform through the injection molding part when the functional member faces the through hole 101, the appearance performance of the exterior trimming part 40 is affected, and preferably, the functional member is arranged to be staggered with respect to the through hole 101 on the glass 10.

The utility model provides a glass assembly with bordure 70, as shown in fig. 6, bordure 70 and set up the edge at glass 10, just the portion of moulding plastics with there is the clearance in borduring 70. During integral injection molding, except for the sprue arranged on the periphery of the glass 10, only one sprue needs to be additionally arranged at the through hole 101 of the glass 10 or near the through hole 101, a material flow channel does not need to be designed, and the subsequent processing procedure of cutting the material flow channel is avoided, so that the appearance effect of the glass assembly is better.

When the injection molding part is thick, the injection molding material shrinks in volume during cooling molding, and generates a shrinkage force on the glass 10 and the bright decoration strip, resulting in optical distortion of the glass surface and the bright decoration strip. In order to solve this problem, as shown in fig. 7, the injection molding part in can be provided with inserts 80, be in according to actual conditions promptly glass 10, the portion of moulding plastics and bright trim an organic whole injection moulding time also mould plastics inserts 80 in the portion of moulding plastics, inserts 80 can attenuate the thickness of the portion of moulding plastics for the power that produces when the portion of moulding plastics contracts reduces, thereby makes the contractile force in the bearing range of glass 10 and bright trim, guarantees that glass surface and bright trim do not produce the deformation.

The through hole 101 in the present invention may be a regular through hole or an irregular through hole, a so-called regular through hole, such as a regular round hole, a square hole, a rectangular hole, an elliptical hole, or a polygonal hole.

The through hole 101 in the present invention may be perpendicular to the glass surface or not, and preferably, the through hole 101 is perpendicular to the glass surface. When the through holes 101 are perpendicular to the surface of the glass, the time for the injection molding material to pass through the through holes is short, and the production efficiency of integral injection molding is improved.

Since the hole is formed in the glass 10, stress concentration is easily generated at the edge of the through hole 101, which affects the use of the glass. In order to solve the stress concentration problem generated at the glass edge, the through hole 101 may be chamfered.

To sum up, the glass assembly of the utility model has the following advantages:

the glass assembly of the utility model adopts an integrated injection molding process, holes are formed in the glass, the injection molding material at the gate flows from one surface of the glass to the other surface through the through holes, and the outer decoration piece is far away from the edge of the glass and appears at the position close to the center of the glass surface when viewed from the overall appearance of the glass assembly, thereby achieving the effect that the outer decoration piece is suspended on the outer surface of the glass; the outer decoration piece is fixed on the outer surface of the glass through the injection molding part, and the bonding firmness between the outer decoration piece and the injection molding part is higher; the sealing performance between the glass and the injection molding part is good.

The above content specifically describes a glass assembly, but the present invention is not limited by the content of the above described specific embodiments, so any improvement, equivalent modification and replacement etc. according to the technical essential of the present invention all belong to the protection scope of the present invention.
