The motor serves as a power source to provide initial power for the swing of the whole rain wiper. The motor drives the transmission connecting rod connected thereto to operate, and the transmission connecting rod further transmits power to the wiper arm, so that the wiper arm can drive the wiper blade to reciprocate, which is a conventional mechanical transmission process for realizing the basic wiping function of the rain wiper. Just like the traditional rain wiper, it can physically wipe and clean the surface of the windshield. The wiper blade comprises a skeleton and a rubber wiper strip, and the skeleton mainly serves to support the rubber wiper strip and transmit power with the transmission connecting rod, so as to ensure that the rubber wiper strip can stably reciprocate with the wiper arm. The rubber wiper strip is a key part for realizing special functions, which adopts an integrated design and comprises a flat strip-shaped wiper strip and a strip-shaped air channel. The wiper strip is responsible for directly contacting the windshield and removing water, frost and snow on the surface of the windshield through physical wiping. The air channel is an airflow transmission channel, which is communicated with the branch exhaust pipe through the air pipe joint and receives airflow from the airflow supply device.The rubber wiper blade is equipped with several air holes connected to the air duct. These air holes have an arc-shaped outer surface, no higher than the wiper blade itself.

The airflow is delivered to the air passages of the wiper blades through the main exhaust pipe and branch exhaust pipes, and then blown out obliquely from the air holes onto the windshield surface. At the same time, the motor drives the wiper arm to make the wiper blades reciprocate. As the rubber wiper blades wipe the windshield, they remove raindrops, frost, and snow from the glass using their own physical scraping. Meanwhile, the airflow blowing out from the air holes continues to work; hot air can quickly melt frost and evaporate water vapor, while cold or normal temperature air can dry or disperse debris. Working together, the two not only effectively clean the area directly covered by the wipers, but also, due to the blowing effect of the airflow, cover a wider area than simply relying on wiping. This quickly and effectively removes various attachments on the windshield that affect visibility, greatly improving the safety of driving in rainy and snowy weather conditions.

[0032] To make the purpose, technical scheme and advantages of the utility model more clear and intelligible, the utility model is further explained in detail below in combination with specific implementation manners and with reference to the drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of the known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0033] Embodiment 1: Application example of a rain wiper for quickly removing water mist, defrosting and removing snow for an automobile windshield

[0034] Application scenario

[0035] On a cold winter morning, a small snowfall has just occurred outdoors, and the vehicle has been parked outdoors for a period of time, a thin layer of accumulated snow covers the front and rear windshields, and part of the snow on the outside of the windshield has also frozen, which seriously affects the driver's vision. At this time, the rain wiper in this embodiment is needed to remove the attachments that affect the vision and ensure driving safety.

[0036] The driver enters the vehicle and starts the vehicle engine. If it is a new energy vehicle, the power supply system is started. The vehicle's electronic systems begin self-checking and normal operation. At this time, the air supply device 31 located in the automobile front compartment is also in standby state. This device can be suitable for the energy type of the vehicle, which is assumed to be a fuel vehicle. The independent fan and heat exchanger contained therein can cooperate with the engine waste heat to generate hot air.

[0037] The driver finds the control option corresponding to the air supply device 31 of the rain wiper through the operation interface or button of the vehicle body central control device. In view of the current situation of snow and ice on the windshield, the heating function is selected to be turned on, so that the air supply device 31 generates positive pressure hot air using the heat energy generated by the engine. Specifically, the central control device sends an opening signal to the electric valve between the heat exchanger and the independent fan air inlet pipeline, so that the inlet air flow passes through the heat exchanger to obtain heat, and the independent fan then sucks the heated air and delivers it out in the form of positive pressure through the main exhaust pipe 32.

[0038] The main exhaust pipe 32 collects hot air, and the air supply device 31 at one end continuously delivers hot air, and the other end distributes the air flow to two branch exhaust pipes 33. The branch exhaust pipes 33 are hung and extended along the layout of the transmission connecting rod 12, and finally connected to the air pipe joint 24 of the left and right rain wiper rubber wiper strips 15, to accurately conduct the hot air flow to the corresponding rain wiper components.

[0039] At the same time, the motor 16 starts to work to provide power for the transmission connecting rod 12, which drives the wiper arm 11 and the wiper blade 13 installed on the wiper arm 11 to reciprocate, just like the wiping action of the traditional wiper when it is working normally. The rubber blade 15 of the wiper blade 13 starts to contact the surface of the windshield. The flat strip-shaped blade 21 of the rubber blade 15 is responsible for directly wiping the windshield to physically remove snow, frost, etc. The internal strip-shaped air duct 22 receives the hot air flow conducted from the air pipe joint 24, and the hot air flow is blown out through the strip-shaped air holes 23 evenly arranged on the outer surface of the rubber blade 15. These air holes 23 blow air in a diagonal direction relative to the windshield, which can make the hot air flow blow to the surface of the windshield in a large area to accelerate the melting of snow, frost and the evaporation of fog.

[0040] In this process, the wiping action of the rubber blade 15 cooperates with the blowing action of the hot air flow to not only clean the area directly wiped by the wiper, but also to cover a wider range due to the blowing of the air flow, so that the snow, frost and fog on the windshield are quickly and effectively removed. The originally blurred windshield gradually becomes clear and transparent, and the driver's vision is greatly improved, so that the driver can clearly see the road conditions, traffic signs and other vehicles in front of the vehicle and around the vehicle, which provides reliable visual guarantee for subsequent safe starting of the vehicle, normal driving and turning, lane changing and other operations, and fundamentally solves the traffic safety hidden danger caused by blocked vision.

[0041] When the attachments on the windshield are completely removed and the vision is restored, the driver can again operate the vehicle body central control device to close the heating function electric valve of the air flow supply device 31, so that the intake air flow no longer obtains heat through the heat exchanger, and at the same time the wiper continues to maintain the conventional intermittent swing or stops swinging according to the demand. The entire device waits for the next time it needs to be used in bad weather to start again.

[0042] Preferably, in the rainy day scene, the vehicle is on the way, and if the windshield is affected by the water film formed by the rainwater on the windshield, the driver can control the air supply device 31 to access the heat pump air conditioner through the central control device, select the output of cold air or hot air, and use the cold air or hot air to quickly blow off the thin water film left after the wiper is wiped, which can accelerate the cleaning efficiency of the mirror surface after the wiper is wiped. The same effect of ensuring clear vision and driving safety is achieved. In this process, the arrangement and installation form of the air duct 22 does not affect the normal operation of the wiper. The integrated design of the wiper strip 21 and the air duct 22 makes the wiper strip 21 and the air duct 22 become an integral whole, avoiding the problem of loose structure caused by splicing or assembly. During the long-term reciprocating swing operation of the wiper, this stable structure can better withstand external forces, reduce displacement, deformation and other situations caused by loose connection between parts, and ensure that the entire rubber wiper strip 15 can always maintain stable performance during use, providing protection for continuous and effective cleaning of the windshield. In the manufacturing link, the wiper strip 21 and the air duct 22 do not need to be produced separately and then assembled complicatedly, but can be produced through one molding process, simplifying the production process, reducing the error probability in the production process, and also helping to improve the production efficiency, so that the product can be mass-produced more efficiently, reducing the production cost. Because the air duct 22 and the wiper strip 21 are integrally formed, there is no air leakage between them caused by poor sealing and other problems. The airflow delivered from the airflow supply device 31 can smoothly and stably pass through the air duct 22 and be blown out from the air hole 23, ensuring that there is a continuous and stable airflow supply when removing the water mist, frost and snow on the windshield, better cooperating with the wiping action of the wiper strip 21 to play a cleaning role and improve the cleaning effect.

[0043] The design of the clamping groove 17 and the clamping strip 18 makes the connection between the rubber wiper strip 15 and the wiper blade 13 very convenient. During installation, only the clamping strip 18 on the rubber wiper strip 15 needs to be aligned with the clamping groove 17 on the wiper blade 13, and then gently inserted to complete the fixation, which is simple and convenient to operate, and ordinary users can easily complete the replacement work of the rubber wiper strip 15 without the help of complex tools or professional skills; Similarly, when disassembled for inspection, repair or replacement, the rubber wiper strip 15 can also be quickly removed from the wiper blade 13, greatly improving the convenience of maintenance; During the later repair and replacement process, only the wiper strip 21 needs to be replaced, without the need to replace other parts, reducing the maintenance cost of consumers.

[0044] It should be understood that the above specific embodiments of the present application are only used for illustrative or explanatory purposes of the principles of the present application, and do not constitute a limitation on the present application. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present application shall be included in the protection scope of the present application. In addition, the appended claims of the present application are intended to cover all changes and modifications falling within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
