Manufacturing method of heating cloth with uniform heating function

Abstract

The invention discloses a manufacturing method of heating cloth with a uniform heating function, which comprises the following steps of S1, cutting a substrate with a corresponding length according tothe total length of a design drawing or a steering wheel rim, and cutting the edge of the substrate according to the shape of the design drawing or the steering wheel rim to form substrates with different widths in the length direction, and enabling the base to be completely attached to and wrap the surface of a rim of the steering wheel, and S2, printing conductive paste on the substrate, so that the surface of the substrate is covered with the conductive paste, printing the conductive paste with different thicknesses according to the different widths of the positions, in the length direction, of the substrate, and enabling the resistance values of the conductive paste in the positions, in the length direction, of the substrate to be uniform. Corresponding conductive heating cloth is made according to the actual shape of the rim of the steering wheel, resistance at all positions is basically the same, the same power heating value is achieved, and the surface of the steering wheel rimis heated evenly.

Description

technical field [0001] The invention belongs to the field of electric heating cloth, and more specifically relates to a method for manufacturing a heating cloth with uniform heating function. Background technique [0002] The latest national standard "Terms and Definitions of Vehicle and Trailer Types" (GB / T 3730.1-2001) has the following definition for a vehicle: a non-rail-mounted vehicle driven by power with 4 or more wheels, mainly used for : Carrying people and (or) goods; towing vehicles carrying people and (or) goods; special purpose. Energy shortages, oil crises and environmental pollution are intensifying, which have a huge impact on people's lives and are directly related to the sustainable development of the country's economy and society. All countries in the world are actively developing new energy technologies. [0003] The steering wheel of a car is a wheel-shaped device that controls the direction of travel. Its function is to convert the force exerted by th...

Problems solved by technology

[0004] At present, the way of adding heating function on the steering wheel is usually to wind the heating wire on the steering wheel, such as figure 1 As shown, but the steering wheel includes rim 1 and spoke 2, the rim itself is not a complete ring, and some steering wheels may have other special shapes such as "D" shape, and there will be parts in the inner ring of the steering wheel for fingers Embedded grooves (protrusions 11), and the connection between the spokes and the rim make it impossible for the heating wire to be wound evenly on the rim surface, that is, the heating of the entire rim surface is uneven
