Abstract
The utility model relates to a hollow windshield for vehicles, which belongs to the field of motor vehicle fittings. The windscreen is composed of at least two multilayer windscreens which are fixedly arranged according to certain spaces and are in parallel mutually. The outer edges of the multilayer windscreens are sealed by heat insulating materials. A closed cavity is formed between the multilayer windscreens, or the hollow windshield is shaped directly. A gas inlet pipe and a gas exhaust pipe can also be arranged inside the cavity and are communicated with a hot-wind gas pump of a vehicle so as to form a circulation return passage of dry hot gases. The hollow windshield for vehicles has the advantages of simple structure and convenient use, and is particularly suitable for driving cabs of motor vehicles with poor sealing performance. A frost-free effect is very obvious.
Description
Affiliated technical field
The utility model relates to automobile-used hollow Windshield.
Background technology
At present the Windshield that assembles on the vehicle under day cold weather, produces frost mist through regular meeting in the winter time, has a strong impact on driver vision, is easy to cause traffic accident.In the case, for guaranteeing to exercise safety, chaufeur is usually wiped frost mist by hand, but is difficult to remove clean.
The utility model content
The technical problems to be solved in the utility model is, the problem at the above existing windscreen for vehicle exists provides a kind of frostless Windshield simple in structure, easy to use, and the dew that can not condense under cold climate has defrosting effect.
For solving the technical scheme that the technical matters proposed takes be, the frostless Windshield of this kind by at least two at regular intervals and the compound glass that is parallel to each other fixed installation form, the outer rim of this compound glass seals with thermal insulation material, makes and forms closed cavity between the compound glass.Such structure can make Windshield have heat-blocking action, thereby is difficult for producing frost mist.
The above heat-insulating and sealing material can be used the plastic cement seal ring, fixes with fastener between the compound glass then.
Another kind of version of the present utility model is that described multilayer Windshield is the hollow sandwich glass material that layer glass forms, and can reach frostless effect equally.
As the further improvement of technical solution, the closed cavity between the above compound glass is equipped with air inlet pipe and freeing pipe, and the hot blast air pump of connection vehicle forms xeothermic gas circulation loop.Even produce frosting so under special circumstances,, can reach the effect of rapid defrosting through xeothermic gas circulation heating.This structure is particularly useful for the self-propelled vehicle of operator's compartment leak tightness difference.
Also have a kind of technical solution to be, filling does not contain the gas of aqueous vapor in the hollow sandwich glass material that aforesaid layer glass forms, but time processing moulding, hollow sandwich.Frostless effect is also very obvious, is particularly useful for the Windshield of motorcycle helmet.

The specific embodiment
Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.
Embodiment 1: this frostless windshield applications is in Agricultural automotive vehicle, mainly by two at regular intervals and double glass 1 fixed installation that is parallel to each other form, the outer rim of this double glass 1 seals with sucked type plastic cement seal ring 2, layer glass is fixing with screw 3, makes and forms closed cavity between the double glass.The closed cavity that this double glass is 1 is equipped with air inlet pipe 4 and freeing pipe 5, and the hot blast air pump of connection vehicle forms xeothermic gas circulation loop.Even produce frosting so under special circumstances,, can reach the effect of rapid defrosting through xeothermic gas circulation heating.The Windshield of this structure can disposablely manufacture a finished product, and also can reequip existing automobile-used individual layer Windshield, and the repacking cost is lower, and dismounting and replacing are also very convenient.
Embodiment 2: this frostless windshield applications is in motorcycle helmet, the hollow sandwich glass material that layer glass 1 forms, but time processing moulding and be installed on motorcycle helmet, and filling does not contain the gas of aqueous vapor in the hollow sandwich.Under the winter cold climate, the glass outer inboard, because of no steam can frosting, hollow pair glass has insulation effect makes the inner layer glass also can frosting, and therefore frostless effect is very obvious.
Claims (5)
