Problems solved by technology

The shape of the traditional bus bar is rectangular or nearly rectangular. This type of design has major defects, resulting in a local high temperature of the glass surface in the middle of the rectangle, sometimes even reaching more than 100 degrees Celsius. The severe uneven temperature of the glass surface will cause the glass to break.

Embodiment Construction

[0013] Please refer to the accompanying drawings for a further description of the present invention.

[0014] Such as figure 1 with figure 2 As shown, the present invention provides a shape of the busbar of the windshield heating wire after electric heating of the automobile, and the shape of the busbar 2 connected and converging with each heating wire 2 is spindle-shaped or radial.

[0015] Use graphic design software to change the shape of the busbar 1 into a spindle shape or a radial shape, and make this image as a photographic negative; follow the screen printing process, expose the photographic negative and the screen frame together, and then develop it, and the printing screen is what you need graphic shape.

[0016] Measure the temperature of the outer surface of the glass at the busbar, and compare the surface temperature with that of products whose busbar is rectangular, as shown in Table 1.

[0017]

[0018] Cooling effect: From Table 1, it can be calculated t...

Abstract

The invention discloses a rear windshield glass electric-heating hot line and bus bar shape of an automobile. Bus bars which are connected and jointed with the line of each hot line are of a spindle shape or a radial shape. The rear windshield glass electric-heating hot line and bus bar shape has the advantages that the glass surface temperature at the bus bar is lower, the glass is difficult to break, the quality of the product is improved, sliver slurry is saved, and the production cost is lowered.

Description

technical field [0001] The invention relates to a bus bar of an electrically heated rear windshield of an automobile, in particular to a shape of a hot wire bus of the electrically heated rear windshield of an automobile with a low heating temperature of the bus. Background technique [0002] When the temperature is low in autumn and winter, there will be more natural phenomena on the rear windshield of the car, such as frost, fog, condensation and even ice and snow. Fog and frost on the rear windshield of the car will seriously affect the driver's vision and endanger driving safety. Therefore, for a reasonably designed car, the rear windshield must have a safe and effective glass electric heater to meet the requirements of safe defogging and defrosting, and at the same time, the glass must not burst due to excessive heating. At present, the heating system of the rear windshield of the car mainly generates heat through the silver paste with a certain graphic layout printed ...
