Abstract
Description
Technical Field
[0001] This utility model relates to the field of defogging glass, and in particular to an electrically heated defogging glass. Background Technology
[0002] In the fields of building curtain walls, automotive windshields and home appliances, electrically heated defogging glass is widely used because it can quickly eliminate condensation or frost on the surface. Traditional electrically heated defogging glass generally adopts the process of directly bonding heating wires (tungsten wires, carbon fiber wires) or conductive films to the opposing inner surfaces of two laminated glass sheets.
[0003] However, since the heating wire and glass are directly bonded together using polyvinyl butyral adhesive to form an integrated structure, if a single heating wire fails due to localized overload or external damage, the entire piece of glass must be replaced. Because the heating wire is extremely thin and embedded within the adhesive layer, the damaged portion cannot be peeled off individually.
[0004] Therefore, how to make the heating wire of the electrically heated defogging glass interlayer replaceable has become a technical problem that urgently needs to be solved. Utility Model Content
[0005] The purpose of this invention is to provide an electrically heated defogging glass to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrically heated defogging glass, comprising: First laminated glass; The second laminated glass is disposed on the side of the first laminated glass, and an adhesive portion is provided on the opposite side of the first laminated glass and the second laminated glass. A heating assembly is used for heating and defogging a first laminated glass and a second laminated glass. The heating assembly includes a connecting portion that is inserted and connected to an adhesive portion. A heating portion is inserted and connected to the middle of the connecting portion. Fixing portions are provided at both ends of the heating portion and on the opposite sides of the first laminated glass and the second laminated glass. A connecting portion for power conduction is provided on the side of the fixing portion.
[0007] Preferably, the adhesive portion includes interlayer adhesive, which is disposed on opposite sides of the first laminated glass and the second laminated glass, and is used for bonding and fixing the first laminated glass and the second laminated glass.

[0009] Preferably, the heating part includes heating filaments, and multiple heating filaments are respectively sleeved in the inner cavity of multiple glass connecting tubes, and the fixing part is disposed at both ends of the heating filaments.
[0010] Preferably, the fixing part includes: A plurality of conductive plates are symmetrically arranged on opposite sides of the first laminated glass and the second laminated glass. The end of the heating wire is inserted and connected to the side of the conductive plate. The connecting part is located on the side of the conductive plate away from the heating wire. A fixed solder joint is provided at the intersection of the heating wire and the conductive plate, and the fixed solder joint is used to fix the heating wire and the conductive plate.
[0011] Preferably, the connecting portion includes: A fixed pressure plate is provided on the side of the conductive electrode plate away from the heating filament; Conductive adhesive is disposed on the opposite side of the fixing plate and the conductive electrode plate, and the conductive adhesive is used to fix the pressure plate and the conductive electrode plate.

[0013] The technical effects and advantages of this utility model are as follows: This invention provides a heating component at the bonding portion between the first and second laminated glass.

[0021] Specifically, the bonding part includes interlayer adhesive 4, which is disposed on the opposite side of the first laminated glass 1 and the second laminated glass 2, and is used for bonding and fixing the first laminated glass 1 and the second laminated glass 2. It should be noted that the first laminated glass 1 and the second laminated glass 2 are made of tempered glass, and the interlayer adhesive 4 is polyvinyl butyral adhesive, which is used to bond and fix the first laminated glass 1 and the second laminated glass 2 together.
[0022] Furthermore, the connecting part includes a glass connecting tube 3, the ends of multiple glass connecting tubes 3 are inserted and connected to the side of the interlayer adhesive 4, and the heating part is disposed in the inner cavity of the glass connecting tube 3.

The heating part includes heating wires 6, and multiple heating wires 6 are respectively sleeved in the inner cavity of multiple glass connecting tubes 3. The fixing part is set at both ends of the heating wires 6. Specifically, the heating wire 6 is a thin tungsten wire with a diameter of less than 1 mm, and the fixing part includes: a conductive electrode plate 5 and a fixing solder joint 501; Furthermore, multiple conductive plates 5 are symmetrically arranged on opposite sides of the first laminated glass 1 and the second laminated glass 2.

[0023] It should be noted that the fixing solder joint 501 is used to fix the heating wire 6 and the conductive plate 5. The conductive plate 5 is made of copper alloy. The fixing solder joint 501 is a tin solder, thereby welding and fixing the heating wire 6 and the conductive plate 5.
