Background technique

Wiper, also known as wiper, water dial, wiper or windshield wiper, is a device used to wipe off raindrops and dust attached to the windshield of the vehicle to improve the driver's visibility and increase driving safety. Cars everywhere have wipers. When the outside temperature is low, the wiper is easy to

The inventor found in the research that the existing automobile has at least the following shortcomings: when the outside temperature of the existing automobile is low, the wiper is easy to freeze, and the wiper is easily broken by forcibly driving the wiper to swing.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a wiper device and a vehicle to improve the problem that the wiper is easy to freeze when the outside temperature is low, and the wiper is easily broken by forcibly driving the wiper to swing.

The present invention is realized in this way:

Based on the above-mentioned first object, the present invention provides a wiper device, including a wiper blade and a water spray device, the wiper blade includes a wiper frame, a wiper strip and a heating device, the wiper strip is mounted on the wiper The heating device is installed on the wiper strip, and the heating device is used to heat the wiper strip; the water spray device includes a heating box and a spray head, and the input end of the spray head is connected to the heating device. The output end of the tank is connected, and the heating tank can provide hot water for the spray head.

The wiper device provided by the present invention is provided with a heating device for heating the wiper strip in the wiper strip, and the wiper strip can be kept at a certain temperature by using the heating device to avoid the wiper strip when the outside temperature is lower than zero degrees Celsius. The strip is frozen on the windshield of the car. The heating box of the water spray device can heat the water inside. When the windshield needs to be cleaned, the water sprayed from here is hot water, which can remove the ice on the windshield. The shavings are melted, so that the wiper strip can better clean the windshield and prevent the wiper from being broken during the start-up swing or swing.

In an implementation of this embodiment: the water spray device further includes a temperature sensor and an electrothermal heating component, the temperature sensor is used to measure the temperature of the outside world, when the temperature of the outside world is lower than the predetermined value of the temperature sensor , the electric heating component starts to work.

The melting point of water is generally zero degrees Celsius, but when the air pressure is different, its melting point will change accordingly, but generally the melting point of water is zero degrees Celsius where people travel, so you can set the predetermined value on the temperature sensor to zero. Celsius, when the car is driven to a temperature equal to or lower than zero degrees Celsius, the temperature sensor senses the outside temperature and makes the electric heating component start to work through an electrical signal. At this time, the water in the heating box can be heated up, which is convenient for melting the windshield. When the outside temperature of the car is higher than zero degrees Celsius, the temperature sensor controls the electric heating component to stop working, which can save electricity.

In an implementation of this embodiment, the heating device is a resistance wire, and the resistance wire is installed in the wiper strip.

The resistance wire can be used to heat the wiper strip very well. The resistance wire has the effect of fast heating and can quickly transfer the heat to the wiper strip, thereby melting the ice chips between the wiper strip and the windshield.

However, in this embodiment, since the wiper strip is provided with a resistance wire, if only the wiper strip is replaced, the connection of the resistance wire will be troublesome and easy. The connection structure on the wiper frame is damaged. If the entire wiper is replaced, the cost is too high. In this embodiment, the wiper strips are set to the first and second strips. When replacing, only the ones with more serious wear and tear need to be replaced. The second wiper strip only needs to be replaced, and neither the first wiper strip nor the heating device needs to be replaced, which makes the replacement more convenient and lower in cost.

In an implementation of this embodiment: the second strip is provided with a plurality of blind holes, the blind holes are located in the direction of the second strip toward the first strip, and the heating device is provided with multiple a plurality of protrusions, and a plurality of the protrusions are respectively clamped in the plurality of the blind holes.

In this arrangement, the second strip can be positioned by the heating device, which is convenient for the installation of the second strip. At the same time, the contact area between the heating device and the second strip can be increased, so that the heat between the heating device and the wiper strip can be increased. The exchange is faster, and the ice chips on the second bar can be melted as quickly as possible.

In an implementation of this embodiment: the wiper frame is provided with a first through hole, the first strip is provided with a second through hole, the first through hole and the second through hole Coaxially arranged, the second strip is provided with a slider and a fastening member, the slider can slide relative to the second strip along the direction of the second strip toward the first strip, and the slider The cross-section of one end of the block away from the first strip is larger than the cross-section of the other end of the slider, and the slider is clamped in the first through hole and the second through hole at the same time. The fastening member is rotatably connected to the second strip, the fastening member rotates relative to the second strip along the width direction of the second strip, and the fastening member is 100 degrees from the midpoint of the second strip. The distance is less than the distance of the slider from the midpoint of the second bar.

When installing the second strip, first align the blind holes on the second strip with the protrusions on the heating device. At this time, the slider is also aligned with the first through holes and the second through holes. After connecting to the first bar, press the slider, let the slider slide in the direction of the first bar toward the second bar, when the end of the slider away from the second bar is flush with the first through hole or lower than the first through hole , turn the fastener, the fastener rotates to wrap the first strip and the wiper frame together, then press the slider from below, and the slider is pushed out from the first through hole, which can restrict the fastener , the surface fastener rotates in the opposite direction, and then presses the wiper onto the windshield, and the end with the larger cross-section of the slider is pressed against the windshield. At this time, the slider cannot continue to slide toward the first through hole, nor can it When withdrawing, the fastener can be restricted, so as to ensure the firmness and stability of the second connection; when disassembling the second, lift the wiper, and the slider can be withdrawn at this time. The second can be removed.
