[0002] At present, in the case of rain and snow in winter, the wiper blade is easy to freeze on the glass, at this time, if the wiper is forced to start, the wiper rubber strip may be damaged, and at the same time, the user has an abnormal sound when using because the rubber strip is hard.

[0003] A patent No. 201710895592.1, published on March 29, 2024, discloses a public specification, which aims to solve the problem that the existing wiper is difficult to ensure not to damage the glass and remove ice and snow, and provides an electric heating type wiper, an electric heating wiper system and a car. The electric heating type wiper includes a wiper swing arm and a wiper blade assembly. The wiper blade assembly includes a mounting sleeve and a wiper strip. The mounting sleeve has a receiving cavity. The wiper strip is connected to the mounting sleeve and seals the opening of the receiving cavity. The inner wall of the mounting sleeve is connected with a first electric heating wire. The wiper blade assembly is provided with a water spraying channel. The electric heating type wiper also includes an electric heating water pipe. The electric heating water pipe has a communication pipe for communicating with the receiving cavity and a water spraying pipe directly facing the surface of the front windshield. The inner wall of the electric heating water pipe is provided with a second electric heating wire capable of electric heating. The utility model has the beneficial effect that different water outlet modes and different temperatures can layer by layer clean different influencing objects on the front windshield, which can effectively remove impurities and ice and snow on the basis of protecting the front windshield.

[0004] There are two solutions to solve this problem in the market at present: one is to increase heating wires on the windshield (wiper stop position), but this solution can only solve the problem of ice, and cannot quickly heat the rubber strip; the other is to increase heating wires on the rubber strip, but this solution will cause the cost of a single room to rise. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a wiper blade with heating function with good heating effect.

[0006] In order to realize the above purpose, the technical scheme adopted by the utility model is as follows: a wiper blade with heating function, comprising a heating spring piece, a rubber strip is arranged in the middle of the heating spring piece, the heating spring piece is in the shape of a back character and is arranged around the rubber strip, and the heating spring piece is clamped in the groove in the rubber strip.

[0007] The heating spring piece is divided into short pieces and long pieces, there are two short pieces in total, the short pieces are symmetrically arranged at the same side of the two ends of the long piece, and the two short pieces are respectively provided with positive and negative wire bundles at one end close to each other.

[0008] A fixing plate is arranged on the heating spring piece and wrapped around the rubber strip, and the fixing plate wraps the end of the short piece.

[0009] The fixing plate is provided with a fixing seat.

[0010] Two ends of the fixing seat are provided with a sheath sleeved on the rubber strip and the heating spring sheet.

[0011] Two ends of the heating spring sheet are clamped with end covers.

[0012] The fixing seat is hingedly connected with a connecting block connected with a vehicle wiper arm.

[0013] An end of the positive wire harness is provided with a connector connected with the negative wire harness.

[0014] The technical effect of the utility model is that the heating spring sheet has the characteristics of ensuring the rubber strip and the glass paste and the function of the thermistor, without adding new parts, reducing the price of single piece, when the wire harness is powered, the spring sheet itself will start heating, and the heat is transmitted to the rubber strip, ensuring that the rubber strip can be quickly heated when the rubber strip is frozen with the windshield, allowing the user to normally use the wiper, and preventing the wiper from being damaged.
