Description

Technical Field

[0001] This utility model relates to the field of wiper blade technology, specifically to a water-spraying wiper blade and wiper. Background Technology

[0002] Currently, most windshield washer spray systems on the market are non-wiper arm / blade spray systems, meaning the washer spray unit is separately installed under the hood. This spray method has obvious drawbacks: it affects the driver's visibility during spraying, and the spray area cannot completely cover the wiper blade area, resulting in incomplete glass cleaning.

[0003] Most existing windshield washer wipers on the market use a wiper arm spray system, which typically involves mounting a spray device on the wiper arm to spray water onto the upper, middle, and lower parts of the wiper blade. While this method is an improvement over traditional separate hood spray systems, it is still not optimal. On one hand, due to limitations in location and cost, the spray path cannot completely cover the wiper's coverage area, resulting in suboptimal cleaning. On the other hand, adjusting the spray angle is difficult due to factors such as wiper arm manufacturing tolerances.

[0004] Furthermore, with the increasing popularity of new energy vehicles, which lack engines and operate quietly during startup, the noise generated by the wipers is relatively more noticeable, leading to a poor driving experience for passengers. Additionally, the existing washer fluid spray mechanism of the wiper arm is not sufficiently concealed, affecting the overall appearance of the vehicle, and some washer fluid wiper products are relatively expensive, hindering large-scale adoption. Utility Model Content

[0005] This invention aims to solve the above-mentioned technical problems by providing a water-spraying wiper blade and a wiper.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: A water-spraying wiper blade includes a blade body. The upper part of the blade body is provided with a clamping part with a cross-section of approximately T-shape. The lower end of the clamping part is connected to a fixing shoulder with a cross-section of approximately rectangular shape. The lower end of the fixing shoulder is provided with two wing structures mirrored with the vertical line of the cross-section of the blade body. The lower end of the blade body is connected to a wiping part. The adhesive strip body is provided with one or two sets of water channels; At least three water outlets are provided along the length of the rubber strip body, and the water outlets are connected to the water channel. After the water spray is started, the water spray direction is towards the side of the wiper direction, and multiple water outlets are respectively arranged in the middle and lower areas along the length of the rubber strip to ensure that the water spray can fully cover the glass wiping area.

[0007] Preferably, when there are two sets of water channels, they are set at both ends of the fixed shoulder or on the two wing structures, and the two ends of the fixed shoulder or the two ends of the two wing structures are arc-shaped structures. Preferably, when the water channel is located at the wing structure position, this position serves as a buffer structure when the wiper blade flips over at its limit position, thereby reducing the wiper's flipping noise, achieving a noise reduction effect, reducing the perception of the wiper's flipping noise by the occupants of the vehicle, and improving driving comfort.

[0008] Preferably, the two wing structures are inclined downwards.

[0009] Preferably, when the water channels are in a set, they are arranged on the scraping part, and the water channels are located in the center position to ensure the stability and coverage of the water spray.

[0010] Preferably, a first material reduction groove is provided between the fixed shoulder and the wing structure.

[0011] Preferably, the upper width of the scraping part is greater than the lower width, and a second material reduction groove is provided on the side of the scraping part. The setting of the first and second material reduction grooves can reduce the amount of material used and reduce production costs while ensuring the structural strength of the rubber strip body, and also helps to reduce the overall weight of the rubber strip.

[0012] A windshield wiper having the aforementioned water-spraying wiper blade, the wiper being mounted on a wiper arm, the wiper arm driving the wiper to brush along the glass in the vertical direction to remove water and stains from the glass, the wiper being able to rotate around the wiper arm to ensure effective cleaning and water spraying functions at different angles.

[0013] With the above structure, this utility model has the following advantages: Excellent water spray effect: By reasonably setting water channels and multiple sets of water outlets on the rubber strip body, and setting multiple water outlets in the middle and lower areas along the length of the rubber strip, the water spray direction is towards the side of the wiper brush direction, which can fully cover the glass brushing area, achieve the best water spray cleaning effect, and effectively remove water and stains from the glass.

[0014] Excellent noise reduction: The water channel is located at the wing structure position, which can act as a buffer structure when the wiper blade flips over at the limit position. This can effectively reduce the sound of the wiper blade flipping over, thus reducing the noise perceived by the passengers and significantly improving driving comfort. It is especially suitable for quiet new energy vehicles.

[0015] Excellent concealment: The water spray structure is integrated into the rubber strip itself. Compared with the traditional method of installing the water spray device on the scraper arm, the water spray structure is more concealed and will not affect the overall appearance and aesthetics of the car.

[0016] Low cost and good manufacturability: By setting a first material reduction groove between the fixed shoulder and the wing structure and a second material reduction groove on the side of the scraping part, the amount of material used is reduced, thus lowering production costs. At the same time, the overall structural design is simple and reasonable, easy to manufacture, and has good manufacturability, making it easy for large-scale production and widespread application.
