Description
Technical Field
[0001] The utility model relates to the technical field of glass structures, in particular to a complex curved surface structure of a windshield glass for an automobile. Background Art
[0002] Vehicle windshields generally use laminated glass. The outer glass and the inner glass are bonded together with an adhesive layer and processed under high pressure to form laminated glass. In order to improve the various performance of laminated glass, relevant functional layers such as sound insulation layer or heat insulation layer are sandwiched between the outer glass and the inner glass.
[0003] Some of the current windshields are designed to fit the upper and lower curved structures of the windshield mounting frame. They only have the ability to block airflow and guide it to the top of the vehicle. They have a single function, and there is still room for optimization in the structure of the glass itself. Utility Model Content
[0004] The purpose of the utility model is to provide a complex curved surface structure of a front windshield for an automobile, so as to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A complex curved surface structure of a front windshield for an automobile, comprising:
[0007] The windshield includes a glass body having an arched three-dimensional structure with curved surfaces in both the horizontal and vertical directions. The vertical cross-section of the glass body is thick at the bottom and thin at the top, and the edges of the glass body are all curved surfaces.
[0008] The edge sealing structure includes a sleeve, and the sleeve is covered at the edge of the glass body.
[0009] Furthermore, the windshield further comprises:
[0010] An argon filling layer, wherein the argon filling layer is opened in the middle of the glass body;
[0011] PVB film, the PVB film is attached to the inner surface of the glass body;
[0012] A filter film, the filter film being attached to the outer surface of the glass body;
[0013] Hydrophobic coating: the inner surface of the PVB film and the outer surface of the filter film are sprayed with a hydrophobic coating.
[0014] Furthermore, the edge sealing structure further comprises:
[0015] An embedded hook is provided on one side edge of the envelope opening;
[0016] An embedded inserting edge, the embedded inserting edge being provided at the other side edge of the envelope opening;
[0017] The seam covering edges are two in number and are fixedly mounted on the outer surfaces of the embedded hook and the embedded inserting edge.
[0018] Furthermore, the edge sealing structure further comprises:
[0019] An inserting edge slot is provided on the outer surface of the edge of the glass body;
[0020] The buckle embedding groove is opened on the inner surface of the edge of the glass body.
[0021] Furthermore, the edge sealing structure further comprises:
[0022] A frame snap-in seat, the frame snap-in seat being fixedly mounted on the bottom side of the outer surface of the envelope;
[0023] The frame snap-in slot is located on the bottom side of the frame snap-in seat.
[0024] Compared with the prior art, the beneficial effects of the present invention are:
[0025] 1. The glass body is fixedly mounted within the mounting frame at the front of the vehicle cab through an edge-sealed structure. The bidirectionally curved glass structure directs airflow to the upper and sides while the vehicle is moving, effectively reducing wind resistance. The arched structure, combined with the glass body's overall thicker bottom and thinner top design, enhances external impact resistance while providing improved mechanical stability. The thicker bottom portion can withstand more weight and pressure, while the thinner upper portion reduces the overall weight while maintaining structural strength and rigidity. The edges of the glass body are polished to a curved surface to reduce stress concentration points and prevent damage to the entire glass body when impacted, further enhancing its strength.
[0026] 2. The embedded hook and the buckle embedded groove are connected to each other, and the embedded insertion edge and the insertion edge slot are connected to each other to strengthen the tightness and strength of the connection between the glass body and the envelope. At the same time, the joint covering edge can provide multiple shielding for the connection seam between the glass body and the envelope, and the sealing effect is improved by relying on its own connection structure.

[0032] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0033] See also Figure 1-4 In an embodiment of the utility model, a complex curved surface structure of a front windshield for an automobile includes a front windshield 1 and an edge sealing structure 2. The front windshield 1 includes a glass body 101. The glass body 101 is an arched three-dimensional structure with curved surfaces in both the horizontal and vertical directions. The vertical cross-section of the glass body 101 is a structure that is thick at the bottom and thin at the top, and the edges of the glass body 101 are all curved surface structures; the edge sealing structure 2 includes a sleeve 201, which is covered at the edge of the glass body 101.
[0034] Specifically, the glass body 101 is fixedly mounted in the mounting frame on the front side of the vehicle cab through the edge sealing structure 2. The bidirectional curved glass structure can guide the airflow to the upper side and both sides when the vehicle is moving, effectively reducing wind resistance. At the same time, the arched structure is combined with the overall thick bottom and thin top design of the glass body 101 to improve the impact resistance of the outer side while providing better mechanical stability. The thicker bottom part can withstand more weight and pressure, while the thinner upper part reduces the weight of the overall structure while maintaining the strength and rigidity of the structure. The edges of the glass body 101 are polished into a curved state to reduce stress concentration points and avoid damage to the entire glass body 101 when the edges of the glass body 101 are hit, further improving the strength of the glass body 101.
[0035] Example 1
[0036] like Figure 4As shown, in this embodiment, the windshield 1 also includes an argon filling layer 102, a PVB film 103, a filter film 104 and a hydrophobic coating 105. The argon filling layer 102 is opened in the middle of the glass body 101; the PVB film 103 is attached to the inner surface of the glass body 101; the filter film 104 is attached to the outer surface of the glass body 101; and the inner surface of the PVB film 103 and the outer surface of the filter film 104 are sprayed with the hydrophobic coating 105.
[0037] In this embodiment, the glass body 101 is designed to be a hollow structure, and the argon filling layer 102 is filled with an inert gas such as argon, which improves the sound insulation effect while hindering heat transfer, and has a certain thermal insulation and heat preservation effect. The PVB film 103 attached to the inside of the glass body 101 can firmly adhere the inner layer of glass fragments together when the glass body 101 is broken by a collision with the vehicle, thereby maintaining the integrity of the broken glass and reducing the probability of glass fragments splashing into the cab. The filter film 104 can avoid glare. The hydrophobic coating 105 coated on the inner and outer sides of the entire windshield 1 structure can prevent raindrops and water mist from staying on the surface of the windshield 1 for too long and blocking the driver's field of vision, and provide the oil film with an adhesion layer separated from the filter film 104, thereby avoiding accidental damage to the filter film 104 when cleaning the oil film and reducing the frequency of replacing the filter film 104.
[0038] Example 2
[0039] On the basis of the first embodiment, in order to supplement the specific method of installing the windshield 1 on the front frame of the cab through the edge sealing structure 2 which is not mentioned in the first embodiment.

The embedded hook 202 is opened at one side edge of the opening of the sleeve 201; the embedded inserting edge 203 is opened at the other side edge of the opening of the sleeve 201; there are two seam covering edges 204, and the two seam covering edges 204 are fixedly installed on the outer surfaces of the embedded hook 202 and the embedded inserting edge 203; the inserting edge slot 207 is opened at the outer surface of the edge of the glass body 101; the snap-fit inserting groove 208 is opened at the inner surface of the edge of the glass body 101; the frame snap-fit seat 205 is fixedly installed on the bottom side of the outer surface of the sleeve 201; the frame snap-fit groove 206 is opened at the bottom side of the frame snap-fit seat 205.
[0041] During specific implementation, the cover 201 covers the edge of the glass body 101, and is clamped to the front windshield mounting frame on the front side of the vehicle cab through the frame clamping seat 205 and the frame clamping groove 206. The embedded hook 202 is clamped to the clamp embedding groove 208, and the embedded insertion edge 203 is plugged into the insertion edge slot 207 to strengthen the connection tightness and strength between the glass body 101 and the cover 201. At the same time, the seam covering edge 204 can be used to multiple-shield the connection seam between the glass body 101 and the cover 201, and the sealing effect is improved by relying on its own connection structure.
