Abstract

The utility model relates to an aluminium alloy vehicle window, which can be used for a railway locomotive, a passenger car, a subway and a light rail vehicle. The aluminium alloy vehicle window aims to solve the technical problems existing in the prior art that the heat loss is serious, the effect of thermal insulation is poor, etc. The aluminium alloy vehicle window comprises a window outer frame, a movable window outer frame, a movable cross beam, a fixed cross beam, a spring cross beam and a glass hollow layer. The utility model is characterized in that the vehicle window outer frame, the movable window outer frame, the movable cross beam and the fixed cross beam are all a two-section split type; separate positions are connected by non-metal heat insulation strips. The heat insulation capability of the utility model is enhanced more than 45 percents to the heat insulation capability of a common vehicle window by the certification of theory calculation and experiment test. Simultaneously, the sound insulation capability of the aluminium alloy vehicle window is enhanced definitely. In addition, the phenomenon of condensing water on the aluminium alloy vehicle window in cold winter can be eradicated and the corrosion resistant performance of the aluminium alloy vehicle window is increased. The aluminium alloy vehicle window can be used for a new manufactured vehicle, and can also be used for vehicle remodification.

Description

Heat insulation vehicle window

Technical field

The utility model relates to a kind of railway locomotive, passenger vehicle, subway and light rail vehicle aluminium alloys vehicle window, the heat insulation vehicle window of specifically a kind of aluminium alloys.

Background technology

China railways locomotive, passenger vehicle, subway and light rail vehicle adopt the aluminium alloys housing to add common tempering hollow glass (or single-glass) formation with window structure mostly at present, the vehicle window frame directly contacts with steel structure of car body during installation, existing vehicle window is that the weight that alleviates car body adopts the aluminium alloys housing, but does not but consider the high thermoconductivity of aluminium alloys.This vehicle window comprises window enclosure, activity parts such as frame, moved cross beam, fixed cross beam outside window, these housings and crossbeam are respectively integrate shaped type, because aluminium alloys has good thermal conduction effect, thereby become the convenient passage of the inside and outside interchange of heat of car body, especially summer and winter this phenomenon more obvious.According to our test determination: the heat of aluminium alloys housing loss has accounted for 30%～40% of whole window thermal losses greatly.At present the general hollow glass of China railways be configured to 5mm tempered glass, 9mm hollow layer and 5mm tempered glass because hollow layer is undersized, also caused heat to lose in heat conducting mode easily.

Summary of the invention

The purpose of this utility model is technical problems such as the heat waste that prior art exists is serious, heat insulation effect difference in order to solve, and the heat insulation vehicle window of a kind of heat waste that provides aluminium alloys little, high insulating effect.

In order to solve the problems of the technologies described above, the utility model comprises window enclosure, activity frame, moved cross beam, fixed cross beam, spring crossbeam and glass hollow layer outside window, it is characterized in that: described window enclosure, activity outside window frame, moved cross beam and fixed cross beam be two sections split type, its gap is connected by nonmetal heat insulating strip.

In the further detailed structure of the utility model, also have following technical characterictic: described window enclosure, the movable gap of frame, moved cross beam, fixed cross beam outside window all have dovetail groove, the two ends of nonmetal heat insulating strip form swallow-tail form, are inserted in the dovetail groove.

In the further detailed structure of the utility model, also have following technical characterictic: described nonmetal heat insulating strip is a H shape.

In the further detailed structure of the utility model, also has following technical characterictic: be provided with the crossbeam heat insulating strip between described fixed cross beam and the spring crossbeam.

In the further detailed structure of the utility model, also have following technical characterictic: the thickness of described glass hollow layer is 10～13mm.

The utlity model has following advantage and good effect: because the utility model has adopted said structure, the passage of the heat conduction on the aluminium alloys window frame is disconnected, and nonmetal heat insulating strip has extremely low pyroconductivity, thereby effectively heat inside and outside the car body is separated, stopped the thermal loss that takes place from the aluminium alloys housing.Prove that through theory measuring and calculating and experiment test the heat-insulating capability of this heat insulation vehicle window has improved more than 45% than common vehicle window, the sound insulation value of vehicle window also improves simultaneously; In addition, also eradicate the phenomenon that occurs condensed water in the winter of cold on the vehicle window, improved the corrosion resistance of vehicle window.The utility model both can be used for newly making vehicle, also can be used for vehicle remoulding.
