Abstract

PURPOSE: A self-heating wiper for vehicles is provided to enable to be effectively used at a low cost in a low-temperature area since the temperature of a whole of a wiper can be simply raised with a separate electrical wire or device. CONSTITUTION: A self-heating wiper for vehicles comprises a hollow section(70) and a plurality of first exothermic-reaction materials. The hollow section is formed in a wiper blade. The first exothermic-reaction materials are filled in the hollow section and are sealed. The first exothermic-reaction material has a liquid or solid powder type for an exothermic reaction. When the wiper blade rotates and simultaneously cleans the glass surface, the first exothermic-reaction materials collide each other and thus the exothermic reaction appears. The heat, which is generated by the exothermic reaction, is delivered to a surface contact part(30) and the temperature of the wipe rises.

Description

Self-heating wiper for car {Self-Heating wiper for car}

The present invention relates to a self-heating wiper for a vehicle, and more particularly, when the wiper blade rotates the glass surface during the wiper operation, heat generated by causing the exothermic reaction materials in the form of liquid or solid powder collide with each other to generate an exothermic reaction. It is delivered to the wiper wipe to raise the temperature of the entire wiper so that the glass surface freezing problem can be solved.

      Generally, the wiper 10 of the vehicle is constructed by assembling a rubber blade 12 to the frame 11 as shown in FIGS. 1 and 2.

   2, the head portion 13 is formed to be fixed to the wiper frame 11, as shown in Figure 2, the head portion 13 is a coupling portion of the shape that can be assembled to the frame 11 (14), the bottom of the blade (12) in contact with the glass surface is formed integrally with the pointed wipe portion 15, which is freely bent to contact the glass surface and has a slight elasticity and can be restored. ) Is constructed to be in constant contact with the glass surface and to clean the glass surface with the contact frictional force.

      FIG. 2 is a cross-sectional view of the wiper blade 12 applied to the flat wiper, in which the head portion 13 is mounted on the plate-shaped strip 11.

      On the other hand, wipers are usually used regardless of the season. For use in low temperature areas, it is important that the blades do not freeze and that cleaning on the glass surface remains stable. Some heat-generating wipers are also known, but because they have a built-in electric heating element and are associated with glass surface eliminators, they must be equipped with complicated electrical wiring, which makes them economical and inconvenient to use.

Thus, the conventional wiper is difficult to remove the frost that forms on the glass surface in a short time when used in a low temperature, the rubber blade is frozen, the cleaning performance and operability is significantly reduced, the life due to the irregular wear caused by freezing There was a problem that there is not enough use failure and durability, such as rapid fall, and the wiper having a heat generating function is a problem that is inconvenient to operate and requires a complicated electric wiring circuit and operating mechanism, because it includes a direct heat generating mechanism, low economical There was this.

     Therefore, the present invention was created in view of the above circumstances, and in the present invention, when the wiper blade is attached to the wiper arm and rotates to clean the glass surface, exothermic reactions occur when the heating materials in the form of liquid or solid powder collide with each other. The purpose of this is to transfer the generated heat to the wiper wipe to raise the entire wiper temperature by itself.

      In the self-heating wiper for a vehicle according to the present invention for achieving the above object, in the vehicle wiper having a wiper blade of a rubber material consisting of a wiping portion on one side and a head portion on the other side in contact with the glass surface of the vehicle,

      A hollow part formed on the wiper blade;

     Including a first exothermic reactant in the form of a liquid or solid powder for the exothermic reaction is filled and sealed in the hollow,

      When the wiper blade rotates the glass surface, the first exothermic reactants collide with each other to generate an exothermic reaction, and heat generated by the exothermic reaction is transferred to the scrubber to increase the wiper temperature. It features.

      In addition, the hollow portion is characterized in that formed in the head portion or wiping portion.

      In addition, the hollow portion is characterized in that formed between the head portion and the wiping portion.

      In addition, the first exothermic reaction material filled in the hollow portion is characterized in that 5% to 50% of the volume of the hollow portion.

      In addition, the second exothermic reaction material is further formed to a predetermined thickness on the inner wall of the wiper blade hollow portion.

      In addition, the third exothermic reaction material is characterized in that it is combined with the rubber at the time of forming the wiper blade.

      In addition, the catalyst material in the form of a liquid or solid powder is characterized in that the hollow portion is filled with the first exothermic reaction material.

      According to the present invention, when the wiper blade rotates the glass surface, the temperature of the blade is increased by the exothermic reaction of the exothermic reactants filled in the hollow portion thereof, and thus, the entire wiper is simply without an electric wiring or an operation mechanism. Since the temperature can be increased, it can be effectively used at low cost in a low temperature region.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

      3 is a perspective view of a wiper blade according to an embodiment of the present invention. 4 is a cross-sectional view of the wiper blade according to an embodiment of the present invention. 5 is a detailed view of a vehicle self-heating wiper blade according to another embodiment of the present invention.

      The self-heating wiper for a vehicle according to the present invention, as shown in Figures 3 to 5, is mounted on the wiper arm (not shown) of the car, the head portion coupled to the wiping portion 30 and the frame 40 to wipe the glass surface 80 The rubber wiper blade 60 which integrally formed 50 is provided.

      The head portion 50 is changed in shape depending on the wiper type. That is, the coupling to the frame 40 and formed to be movable along the groove of the frame according to the type or specification, or as shown in Figure 3, to combine as covering the outside of the frame 40, to the other frame 40 It may vary depending on the type of wiper that engages the blade 60.

     The blade 60 is formed with a hollow portion 70. The hollow part 70 may be selectively formed at the head part 50 and the wiping part 30 or may be simultaneously formed, and may be formed between the wiping part 80 and the head part 50. The size of the hollow portion 70 or the volume of the entire space may be determined in consideration of the overall performance of the wiper blade 60 and economical efficiency for reducing material usage.

     The hollow part 70 is filled with the first exothermic reaction material in the form of a liquid or solid powder capable of causing an exothermic reaction in a volume of about 5 to 50% of the total volume of the hollow part 70, and the hollow part 70. Heat generation by the neutralization reaction of the first exothermic reactant in the c).

     When the entire space of the hollow part 70 is filled with the first exothermic reactant, the amount of exothermic reactants can be maximized, so that a high amount of heat can be obtained. However, the mass motion in the hollow part 70 space is increased. There is a disadvantage that is not smooth. Accordingly, the amount of the first exothermic reactant filling the hollow part 70 has been found to be limited to an amount not exceeding 50% of the total volume of the hollow part.

      The first exothermic reactants filled in the hollow part 70 have the exothermic reaction due to collision of the first exothermic reactants in the form of liquid or solid powder when the wiper blade 60 rotates to clean the glass surface 80. The heat generated by the exothermic reaction is transferred to the wiping unit 30 to increase the temperature of the entire wiper.

      Representative exothermic reactants include hydrochloric acid, sodium hydroxide or sulfuric acid and water, which are acid base neutralizing reactions, and exothermic reactions occur when hydrochloric acid, sodium hydroxide or sulfuric acid and water neutralize.

      As an example of a typical exothermic reaction, there are many examples of acidic acid neutralization reactions, and the reaction of hydrochloric acid with sodium hydroxide, sulfuric acid and water can be seen as a typical example.

     Meanwhile, a second exothermic reaction material (B), which is different from the first invention reactant material (A), is formed on the inner wall of the hollow portion 70 of the wiper blade 60 by adhesion or coding at a predetermined thickness. You may.

     Meanwhile, another second exothermic reaction material (B) may be combined with the rubber which becomes the base material when the wiper blade 60 is formed.

     In addition, the hollow portion 70 may be filled with the catalyst material (C) in the form of a liquid or solid powder.

     The first exothermic reactant (A) and the catalyst filled in the hollow portion 70 may be the second exothermic reactant (B) formed on the inner wall of the hollow portion 70 or the second exothermic reactant (B) included in the blade itself. In the case of contacting), heat generated by the exothermic reaction may be transferred to the wiper wiping unit 30 to increase the temperature of the entire wiper.

     The catalyst is a liquid or metal material such as chromium or sodium, and is used as a material used to control the time at which exothermic reaction occurs or to control the amount of heat generated. When chromium and an acid solution meet alcohol, heat is generated and chromium is oxidized. By adjusting the amount of chromium, the amount of heat generated and the duration of heat generation can be controlled.

     In general, catalysis involves chemical reactions between the catalyst and the reactants to form intermediates that easily react with one another or with other reactants to produce the desired end product. When a reaction occurs between the intermediate and the reactant of the chemical reaction, the catalyst is regenerated. The type of reaction between the catalyst and the reactant varies.

The self-heating wiper for a vehicle according to the present invention configured as described above generates heat by exothermic reaction of exothermic reactants filled in the hollow part 70, and the generated heat is transferred to the wiping unit 30 by contacting the glass surface 80. At the same time, the entire wiper is heated. Therefore, in addition to the need for complicated electrical wiring for the wiper heat generation during the freezing or frosting of the glass surface 80, the wiper heat generation may occur in the wiper operation without a separate heating means, and thus, it may effectively contribute to safe driving.

While the invention has been described in connection with the preferred embodiment, it will be readily apparent to those skilled in the art that various modifications and variations are possible without departing from the spirit and scope of the invention, all such modifications and modifications being within the scope of the claims It belongs to the range described.
