Abstract

The utility model discloses an electrical heating wiper, which belongs to the technology field of vehicle used wiper. The utility model is characterized in that a parallel brace rod is inserted symmetrically between two slim strip metal clips of slightly bending arc shape to support a slim triangle rubber wiper blade, which is covered the wiper arm with a clamping jaw cover in the middle; an electric connector that is installed on the clamping jaw cover is connected with the external circuit with an end cover on each end. The arrangement is that a flexible thin heating film is installed between the brace rod and the metal clip and is led to the electric connector via the conducting line. The positive effect is that the heating element is thin in thickness and occupies hardly any space, which does not affect the original structure and the esthetics. Owing that the surface heating is used, which is quite high in heating conversion rate and heating speed, an over high local temperature will not be caused, so that the service life can be prolonged and the frozen ice on the window can be dissolved quickly,which is a practical design.

Description

The electro heat wiper

Technical field

Belong to the wiper technical field that automobile is used.

Background technology

Existing wiper does not have the function of heating, and in the cold place of weather, the back rain strip device that snows is frozen on the windshield inactive, has only that manually will avenge could normal use after removing.When snowing, wiper can not be cleaned out snow, will influence driver's sight line like this, causes the generation of traffic accident easily.Though the electro heat wiper is also arranged at present, make vehicle wiper that the function of heating be arranged, mainly adopt heating wire to heat, and mainly be that heating wire is installed in the blade insert of wiper, when heating, at first, heat is spread out of dissolve ice and snow again the rubber heating.The major defect that adopts this type of heating is that heat produces slowly, and heating concentrates on inside, and it is bad to scrape brushing effects, and rubber is the bad conductor of heat, and this just makes the rubber temperature inside too high, and rubber is aging easily, also makes the wiper lost of life.

Summary of the invention

The utility model will provide a kind of heating rapid, and wiper is effective, the electro heat wiper of long service life.

The technical scheme that the utility model is taked:

The electro heat wiper, be included between the elongated strip metal clip sheet of two slightly crooked circular arcs, embedding one symmetrically is with parallel brace rod to support an elongated triangular shape blade insert, cover on it by the Wiper arm lid, jaw lid is equipped with at the middle part, and has and be installed in the electric coupler that jaw covers and be connected with external circuit, and there is end cap at two ends, its scheme is: a flexible thin heating film is arranged between brace rod and metal intermediate plate, and heating film has conductor wire to guide to electric coupler.Described flexible thin heating film can be that exothermic body is non-metal electric heating film or the silica gel heating plate that material that the metal electric heating membrane made of metallic paper or metal filament or exothermic body are carbon containing or argentiferous is made.Described flexible thin heating film is long and narrow side's bar, and respectively there is a long pin T v notch v on rectangular center of symmetry both sides.

Good effect behind enforcement the utility model is: because the heater element characteristics are thin thickness, heating is rapid and even, is easily installed between wiper blade rubbers scraping blade and the metal intermediate plate, can be along with any distortion of wiper and bending; Account for volume hardly, the flexible thin heater element is installed, do not influence original design and its aesthetic property; The flexible thin heater element is planar heating, and the heat conversion ratio is very high, and this has just saved the energy, and the heat that planar heat producing body sends will soon spread out of, and firing rate is just very fast like this; For linear heating element such as heating wire, it is more even to generate heat, and can not produce the too high phenomenon of local temperature, thereby extend service life.The flexible thin heater element is installed between blade insert and the metal intermediate plate, be close on the metal intermediate plate, can heat very fast pass to the ice and snow that freezes, accelerated the speed of ice and snow dissolving.

The specific embodiment

Now the utility model is described in further detail in conjunction with the accompanying drawings

The electro heat wiper, be included between the elongated strip metal clip sheet 2 of two slightly crooked circular arcs, embedding one symmetrically is with parallel brace rod 1 to support an elongated triangular shape blade insert, cover on it by Wiper arm lid 5, jaw lid 6 is equipped with at the middle part, and has the electric coupler 4 that is installed on the jaw lid 6 to be connected with external circuit, and there is end cap 7 at two ends, its structure is: a flexible thin heating film 3 is arranged between brace rod 1 and metal intermediate plate 2, and heating film 3 has conductor wire to guide to electric coupler 4.Described flexible thin heating film 3, its structure is the upper and lower slim heatproof insulating material that is, the centre is the sandwich construction of exothermic body, and exothermic body can be that exothermic body is the non-metal electric heating film that material that the metal electric heating membrane made of metallic paper or metal filament or exothermic body are carbon containing or argentiferous is made.Described flexible thin heating film 3 is long and narrow side's bars, and respectively there is a long pin T v notch v 8 on rectangular center of symmetry both sides.
