Description

Technical Field

[0001] The present application relates to the technical field of windshield wipers, and in particular to a multifunctional windshield wiper. Background Art

[0002] Windshield wipers, also known as wipers, water paddles, wipers, or windshield wipers, are devices designed to clear raindrops and dust from a vehicle's windshield, improving the driver's field of vision and thereby enhancing driving safety. These devices are required by law in almost all regions of the world, including the rear windows of hatchbacks, SUVs, and other vehicles. In addition to cars, other modes of transportation, such as trains and trams, are also equipped with wipers.

[0003] When rain falls, wipers play a crucial role. Their reciprocating motion scrapes rainwater from the center of the windshield to the sides or bottom, ensuring an unobstructed view for the driver. This mechanical device primarily consists of a motor, a connecting rod mechanism, a wiper arm, and a wiper blade. The motor, acting as a power source, drives the connecting rod mechanism, which in turn drives the wiper arm back and forth. The wiper blade, attached to the wiper arm, moves with it, ultimately removing the rain.

[0004] Conventional wipers are mainly used to clear rain from the windshield to keep the driver's field of vision clear. However, in winter or on snowy days, snow or frost often accumulates on the windshield, and conventional wipers are not very effective in clearing this.

[0005] There are some manual snow shovels and heated wipers on the market, but they are either inconvenient to use or consume a lot of energy. When frost and snow appear on the windshield, users need to get out of the car and use manual snow shovels, which affects the user experience. While heated wipers can melt frost, they consume a lot of power and are not very effective on thick snow, so there is room for improvement. Utility Model Content

[0041] The embodiment of the present application discloses a multifunctional wiper. Figure 1The wiper includes a wiper body 1, a soft wiper blade 2, a hard wiper blade 3, and a switching assembly 4. The wiper body 1 is made of stainless steel or an alloy material. Stainless steel or an alloy material has high strength and corrosion resistance, and can serve as a good skeleton of the wiper. This makes the prepared wiper less susceptible to damage and corrosion from external rain and snow, thereby extending its service life. The outer surface of the wiper body 1 is also coated with a paint layer (not shown in the figure), which is formed by spraying or electroplating. The paint layer can improve the aesthetics of the outer surface of the wiper body 1 and enhance the visual effect.

[0042] The wiper body 1 has a receiving slot 5, with a soft scraper blade 2 movably mounted at the opening of the slot 5. Made of a flexible material (such as rubber), the soft scraper blade 2 is used to scrape rainwater from the windshield. A hard scraper blade 3 is also movably mounted within the slot 5, with its movement forming an acute angle with the movement of the soft scraper blade 2. A clearance slot is also provided on the wiper body 1, communicating with the receiving slot 5 and allowing the hard scraper blade 3 to pass through. The hard scraper blade 3 is used to scrape frost and snow from the windshield. The hard scraper blade 3 has an arc-shaped outer edge, which provides excellent softness and enhances user comfort when in contact with the hard scraper blade 3.

[0043] The switch assembly 4 is installed in the placement groove 5 and is connected to both the soft scraper blade 2 and the hard scraper blade 3. The switch assembly 4 is used to control the movement of the soft scraper blade 2 and the hard scraper blade 3. When the soft scraper blade 2 moves away from the notch of the placement groove 5, the hard scraper blade 3 passes through the clearance groove and out of the wiper body 1.

[0044] When the user needs to shovel frost or snow, the switching component 4 can be operated to control the original soft scraper blade 2 to retract into the placement slot 5, while the hard scraper blade 3 is extended from the placement slot 5. The hard scraper blade 3 is used to push and scrape the snow on the windshield to clear the frost and snow. By changing the use state of the hard scraper blade 3 and the soft scraper blade 2 by the switching component 4, the wiper can switch between wiping water and shoveling snow, realizing the multifunctionality of the wiper. It can be used as a traditional wiper and can quickly clear snow on snowy days, thereby improving driving safety and convenience, and enhancing the user experience.

[0045] Specifically, the switching assembly 4 includes a gear 41, a driver 42, a first rack 43, and a second rack 44. The gear 41 is rotatably connected to the placement slot 5. The driver 42 is connected to the gear 41 and is used to control the rotation of the gear 41. The driver 42 is a micromotor or an electric motor. The first rack 43 is meshed with the gear 41 and connected to the soft scraper 2. The second rack 44 is also meshed with the gear 41 and connected to the hard scraper 3.

[0046] The driving member 42 can control the rotation of the gear 41. The rotation of the gear 41 can drive the first rack 43 and the second rack 44 to move linearly. The first rack 43 can drive the soft scraper 2 to move, and the second rack 44 can drive the hard scraper 3 to move, thereby realizing the adjustment and switching of the soft scraper 2 and the hard scraper 3.

[0047] In some embodiments, the hard scraper blade 3 is detachably connected to the second rack 44. The second rack 44 defines a slot 6, into which the hard scraper blade 3 is snapped, initially positioned by static friction. The hard scraper blade 3 is then secured to the second rack 44 using a fastener, such as a removable bolt or screw. If the hard scraper blade 3 becomes damaged, it can be removed and replaced, reducing maintenance costs and improving the wiper's practicality.

[0048] Furthermore, the hard scraper blade 3 is fixedly connected to a plurality of reinforcing ribs (not shown), which are spaced apart along the length of the hard scraper blade 3. The reinforcing ribs can increase the resistance of the hard scraper blade 3 to breakage, extending the service life of the hard scraper blade 3 to meet the needs of snow shoveling and maintain durability.

[0049] The multifunctional wiper of the present application embodiment operates as follows: when the user needs to shovel frost and snow, the user can operate the switching component 4 to control the original soft scraper blade 2 to retract into the placement slot 5, while the hard scraper blade 3 extends from the placement slot 5. The hard scraper blade 3 is then used to push and scrape the snow on the windshield to clear frost and snow. By changing the use state of the hard scraper blade 3 and the soft scraper blade 2 through the switching component 4, the wiper can switch between wiping water and shoveling snow, thus realizing the multifunctionality of the wiper. The wiper can be used as a traditional wiper and can also quickly clear snow on snowy days, thereby improving driving safety and convenience.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
