Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile auxiliary, mainly relates to the technical improvement of car window and rear -view mirror, specifically a main and vice driver car window glass and rear -view mirror's quick defogging and defrosting snow device. BACKGROUND

[0002] In the current automobile use scene, rainy day, foggy day, ice and snow day and so on weather condition brings many safety hidden troubles to vehicle driving. When encountering these weather, the left and right rear -view mirror of vehicle, main and vice driver car window glass and front and back windshield often appear the condition of being attached by raindrop, fogging, frosting, icing or being covered by snow, this makes the driver difficult to clearly observe the left and right and front and back of vehicle. Especially when the vehicle needs to operate such as lane changing, turning, because the rear -view mirror cannot be seen, the surrounding traffic situation cannot be accurately judged, greatly increases the risk of traffic accident.

[0003] As for the existing automobile configuration, although the rear -view mirror of part vehicle has heating function, but this heating mode has obvious defects, its heating speed is too slow, the actual use effect is not good, cannot effectively realize the function of quick water removal, defogging, defrosting, deicing and snow removal, it is difficult to meet the driving safety demand under the rainy and snowy weather. In recent years, some new energy vehicle enterprises try to popularize electronic rear -view mirror as the optional configuration of vehicle. However, electronic rear -view mirror also has a series of problems. First of all, its cost is high, at least 0.5-1.5 ten thousand yuan, which undoubtedly increases the purchase cost of consumers. Secondly, from the appearance design, electronic rear -view mirror is relatively long, which does not meet the aesthetic preference of most consumers. Thirdly, the maintenance cost of electronic rear -view mirror is also very high in the later period, which makes many consumers step back. More importantly, electronic rear -view mirror only solves part of the problem of traditional rear -view mirror, and still cannot solve the defogging, defrosting, deicing and snow removal problem of front and back windshield in rainy and snowy weather. Even in some cases, the rainwater on the rear -view mirror of vehicle can be dried by heating, but at this time, there are still water droplets, snow or ice on the main and vice driver car window, which still blocks the line of sight of the driver observing the rear -view mirror, so that the driver cannot fully understand the traffic condition around the vehicle, and cannot solve the driving safety hidden trouble in rainy and snowy weather.

[0021] The utility model has the beneficial technical effects:

[0022] 1. Rapid water mist, frost, ice and snow removal: high-speed hot air blowing can quickly remove water droplets, fog, frost, ice and snow on the surface of the rearview mirror 2 and the main and deputy driver window glass. Compared with the traditional heating method, this method significantly improves the speed of removing water mist, defrosting, deicing and snow removal of the rearview mirror 2 or the main and deputy driver window, and ensures that the driver can still clearly observe the traffic conditions around the vehicle in rainy and snowy weather conditions.

[0023] 2. Comprehensive coverage of key areas: The air outlets are designed in two groups, one group is designed on the rearview mirror base 31 for blowing air flow to the local area of the driver and passenger windows, and the other group is designed inside the housing 21 of the left and right rearview mirrors 2, which can target the key areas of the left and right rearview mirrors 2 and the driver and passenger windows.

This not only improves the effect of water mist, frost, ice and snow removal, but also reduces the response time of the system and improves the overall performance. The air supply device 1, the exhaust pipe system and the air outlet device are highly integrated and installed in the front compartment of the vehicle, and connected to the positions of the rearview mirrors 2 and the driver and passenger windows through branch exhaust pipes 12. This design not only saves space, but also facilitates maintenance and repair.

[0026] 5. Easy to control: Through the central control equipment in the vehicle body, the driver can easily control the start, stop and heating function of the air supply device 1, or use voice control to control without contact. This user-friendly control method improves the operability of the system, allowing the driver to quickly adjust the working state of the system according to actual needs.

[0043] In order to make the utility model's purpose, technical scheme and advantage more clear and obvious, below combining specific implementation and referring to the attached drawing, the utility model is explained in further detail.Should understand, these descriptions are only exemplary, and not to limit the scope of the utility model.In addition, in the following explanation, the description of known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0044] Embodiment 1: A description of the use process of the rapid defogging and defrosting device for the main and auxiliary driver's window glass

[0045] Scenario One: A cold winter morning

[0046] On a cold winter morning, the outdoor temperature is extremely low, and the vehicle has been parked overnight. A thick layer of ice and frost has formed on the main and auxiliary driver's window glass, almost completely blocking the driver's view of the rearview mirror 2. From inside the vehicle, it is almost impossible to see the road and the surrounding environment outside the vehicle and the scene in the rearview mirror 2.

[0047] Use process: as shown in Figure 3 , 7 , the vehicle owner enters the vehicle and starts the vehicle, and turns on the vehicle window defrosting and snow removal device of the embodiment. The air supply device 1 is quickly started, and according to the preset program of the vehicle control system or the heating mode selected manually by the vehicle owner, it is assumed that the engine waste heat is used for heating. The heat exchanger starts to absorb the heat energy generated by the engine, and the independent air blower sucks in the heated air and delivers it to the branch exhaust pipe 12 through the main exhaust pipe 11. The branch exhaust pipe 12 guides the hot air flow to the vehicle window air outlet 3 in the rearview mirror base 31. The vehicle window air outlet 3 is arranged vertically and has an inclination angle. The hot air flow is obliquely blown to the lower and front part of the vehicle window glass, that is, the part between the straight line direction formed by the rearview mirror 2 and the driver's head area. Because the hot air flow is concentrated on the key area, the ice and frost begin to melt rapidly and are blown away by the hot air flow. Within a few minutes, the vehicle window glass, which was completely covered by ice and frost, gradually becomes clear, and the driver can clearly see the situation outside the vehicle, including the visible range of the rearview mirror 2, so that the vehicle can be safely started and driven away from the parking space. In snowy weather, snowflakes fall on the vehicle window, similar to the use process in this scenario.

[0048] Scenario Two: During driving in rainy weather

[0049] Pre-use condition: The vehicle encounters rainy weather during driving, and rain continuously hits the main and auxiliary driver's window glass. Although the vehicle window glass has a certain inclination angle, a layer of water film still forms on the vehicle window, seriously affecting the driver's view of the rearview mirror 2 through the vehicle window. Especially when the vehicle turns or changes lanes, the driver cannot accurately determine the position of the surrounding vehicles, posing a safety hazard.

[0050] Use process: as shown in Figure 3 , 7As shown, the new energy vehicle driver perceives that the line of sight is blocked during driving, presses the button of the device in the vehicle to select the hot air mode provided by the heat pump air conditioner, or executes the function through the vehicle voice control. At this time, the cold and hot air fan rotates at high speed, and the positive pressure hot air generated by the electric heating device is transmitted to the vehicle window air outlet 3 through the main exhaust pipe 11 and the branch exhaust pipe 12. The hot air flow blows to the vehicle window glass at a specific inclination angle, and the rainwater on the vehicle window is quickly evaporated and blown away. With the continuous blowing of the hot air flow, the water film on the vehicle window glass quickly disappears, the driver's line of sight becomes clear, and the scene in the rearview mirror 2 can be clearly seen, ensuring safe driving during rainy driving, smoothly completing the turning and lane changing operations, and avoiding traffic accidents that may be caused by poor visibility.

[0051] Embodiment 2: A description of the use process of the quick water mist and frost and snow removing device of the rearview mirror.

[0052] Scene one: driving after winter snowfall

[0053] Before use: After a night of snowfall, a thick layer of snow accumulates on the left and right rearview mirrors 2 of the vehicle, and a thin layer of ice condenses on the mirror surface due to the temperature difference between the vehicle interior and the outside, completely blocking the line of sight of the rearview mirror 2, and the driver cannot observe the situation behind the vehicle through the rearview mirror 2. In such a situation, driving the vehicle poses a great safety risk whether it is lane changing or reversing.

[0054] Use process: as shown in Figure 1 、 2 , 7, the vehicle owner starts the vehicle after getting on the vehicle, and at the same time, the rearview mirror 2 defrosting and snow removing device is turned on. The airflow supply device 1 starts to work, assuming that it is connected to the engine heat source to heat the airflow (the engine gradually heats up after starting, and can provide a stable heat source for the device). After the air is heated, it is transmitted to the branch exhaust pipe 12 through the main exhaust pipe 11, and then to the rearview mirror air outlet device in the rearview mirror 2 housing 21. The 3 air outlets (inclined inwardly) on the upper eaves 23 of the rearview mirror 2 and the 2 air outlets (also inclined inwardly) on the left and right eaves 25 start to blow high-speed hot air flow. The hot air flow blows along the respective inclined surfaces to the mirror surface of the rearview mirror 2. The horizontal narrow air flow of the upper eaves 23 expands downward, quickly melting the snow and ice layer, and blowing away the melted water; the vertical narrow air flow of the left and right eaves 25 expands obliquely downward, effectively removing the snow and ice debris on the edge and corner of the mirror surface from the side. After only a few minutes, the mirror surface of the rearview mirror 2 becomes clear and clean, and the driver can clearly see the situation of the vehicle and the road behind, and can drive the vehicle safely, smoothly performing turning, lane changing and other operations, and ensuring safe driving.

[0055] Scene two: driving in rainy weather

[0056] Before use: the vehicle is driving in the rain, a large number of raindrops constantly hit the rearview mirror 2 mirror surface, even if the rearview mirror 2 has a certain rainproof design, but because of the rain hitting the rearview mirror 2, the mirror surface is still quickly covered with rain, forming a water curtain, causing the rear view to be blurred, the driver is difficult to accurately judge the position and driving state of the rear vehicle, which poses a serious threat to driving safety.

[0057] During use: as shown in Figure 1 , 2 7, the driver realizes that the rearview mirror 2 line of sight is blocked, and immediately starts the device and selects the mode of connecting the cold air provided by the heat pump air conditioner (cold air can quickly reduce the temperature of the rain on the mirror surface, making it easier to be blown away and evaporated). The high-speed positive pressure cold air generated by the air supply device 1 reaches the rearview mirror air outlet 22 through the pipe system. The cold air blown out of the air outlet on the upper mirror eave 23 and the left and right mirror eaves 25 blows along the inclined surface to the mirror surface, quickly blowing away the rain on the mirror surface into small droplets and accelerating its evaporation. Under the continuous blowing of cold air, the clarity of the rearview mirror 2 mirror surface gradually recovers, and the driver can clearly see the key signals such as the turn signal and brake light of the vehicle behind, so as to accurately grasp the timing of lane changing and the safety distance from the vehicle behind, ensuring safe driving in heavy rain.

[0058] Example 3: a use process of a rapid deicing device for the main and auxiliary driver's window glass and rearview mirror.

[0059] Before starting the vehicle: the vehicle is parked outdoors, and the window glass and rearview mirror 2 are covered with raindrops, causing serious obstruction of the line of sight.

[0060] Start the vehicle: the driver gets into the vehicle and starts the engine. At this time, the electronic system of the vehicle completes self-checking and enters an operable state.

[0061] Start the de-rain mode: the driver finds the control options of the deicing device through the control interface of the vehicle center console, and selects the de-rain mode suitable for rainy weather (assuming the cold air mode provided by the heat pump air conditioner).

[0062] The center console sends a signal to the cold air blower to control its cold air output function, and sends a start signal to the pressure air pump 13 (if any) to increase the flow rate and air volume of the air flow and enhance the de-rain effect.

[0063] The cold air blower rotates at high speed, generating positive pressure cold air that is transmitted to the branch pipe 12 through the main pipe 11, and the branch pipe 12 delivers the cold air to the rearview mirror air outlet device in the left and right rearview mirror 2 housings 21, as well as the connecting part between the main and auxiliary driver's window glass and the rearview mirror 2, and the continuous and integrated car window air pipe along the top edge of the window frame and the two sides of the car frame.

[0064] Actual results during rain removal:

[0065] Rearview mirror 2 rain deflector: such as Figure 1 , 2 As shown in Figure 7, the rearview mirror vents 22 located on the upper rim 23, left rim 24, and right rim 25 of the rearview mirror 2 begin to operate, blowing out high-speed cold air at a specific tilt angle. The four inwardly tilted vents on the upper rim 23 form a horizontally narrow airflow that extends downwards, while the three inwardly tilted vents on the left and right rims 25 form a vertically narrow airflow that extends downwards. This cold airflow quickly blows onto the mirror surface of the rearview mirror 2, breaking up raindrops on the mirror surface into small water droplets and accelerating their evaporation. This allows the driver to clearly see the image in the rearview mirror 2, accurately judge the situation behind the vehicle, and provide a clear field of vision for lane changes, turns, and other operations.

[0066] Rain filters for driver and passenger side windows: Figure 3 , 7 As shown, vertically arranged and angled air vents 3 on the driver and passenger side windows direct high-speed cold airflow obliquely towards a lower and forward section of the window glass (located between the rearview mirror 2 and the driver's head area). Simultaneously, window ducts arranged along the window frame also propel high-speed cold airflow across the entire window area. This cold air quickly disperses and evaporates raindrops on the window glass, restoring the driver's clear vision of the surrounding area and the rearview mirror 2. This ensures the driver can clearly observe traffic conditions around the vehicle, preventing traffic accidents caused by obstructed vision.

[0067] End of use: When the rain subsides or the visibility through the windows and rearview mirror 2 has returned to clear and the driver no longer needs the device to work, the hot and cold air blowers and pressurized air pump 13 (if any) can be turned off via the center console. The device will then stop working and await the next use.

[0068] Example 4: The air vents for the driver and passenger side windows are continuous, integrated window ducts arranged along the top edge of the window frame and both sides of the vehicle frame, such as... Figure 4 , 5 As shown, the window duct is connected to a branch pipe of the exhaust pipe, which can blow cold / hot airflow at high speed to the entire window area; the window duct is an integrated design of the window rubber strip 4 on the outer side of the window, the window rubber strip 4 on the outer side has a built-in duct and several air outlets 41, which are arranged and installed along the window frame.

[0069] Use Case: The following is the usage and operation process of this device in snowy weather:

[0070] During the vehicle driving process: a layer of snow or even thin ice is accumulated on the main and assistant driver's window glass, which seriously affects the driver's observation of the outside situation, and the vision is seriously blocked.

[0071] Start the snow and ice removal mode (for example, using the engine heat source):

[0072] The driver finds the control options of the device through the control interface of the center console in the vehicle and selects the mode of using the engine heat source for heating.

[0073] The center console sends an opening signal to the electric valve on the heat exchanger beside the engine cylinder or exhaust pipe, so that the air sucked by the independent air blower passes through the heat exchanger and is heated. At the same time, if the pressurized air pump 13 is equipped, it will also be started to increase the flow rate and air volume of the airflow, and enhance the snow and ice removal effect.

[0074] The heated and pressurized air is transmitted to the branch exhaust pipe 12 through the main exhaust pipe 11, and the branch exhaust pipe 12 delivers hot air to the window air pipe arranged continuously and integrally along the top edge of the window frame and the two side edges of the vehicle frame of the main and assistant driver's window. The window air pipe is designed integrally with the window rubber strip 4 on the outer side of the window, and the rubber strip is provided with a plurality of air outlets 41, and the hot air can be blown from the air outlets 41 to the window surface in a way of surrounding the window from three directions.

[0075] Actual effect during snow and ice removal process:

[0076] The hot air is blown out at high speed from the air outlets 41 on the window rubber strip 4 and blows to the entire window area. For the snow on the window, the hot airflow first causes the surface to begin to melt, and with the continuous blowing of hot air, the snow gradually becomes a water flow and falls down, and for the thin ice on the window, the hot air quickly causes it to melt and then dry. Within a few minutes, the window glass covered with snow and ice gradually becomes clear and transparent, and the driver can clearly see the road, traffic signs, and surrounding vehicles and pedestrians outside the vehicle, greatly improving the safety of driving in snowy weather. Whether the vehicle is starting, driving, turning, parking, or other operations, the surrounding environment can be accurately judged to avoid traffic accidents caused by blocked vision.

[0077] End of use: when the snow and ice on the window glass are completely removed and the vision is clear, the driver can operate the center console again to close the independent air blower and the electric valve if the engine heat source mode is used, and the pressurized air pump 13 (if any), and the device stops working, waiting for the next use requirement.

[0078] Example 5: on the basis of the above examples, as Figure 9The main and vice driver window glass air outlet device and the rearview mirror air outlet device are installed on the main and vice driver window triangular area of the existing vehicle and the rearview mirror of the existing vehicle in a split structure form through connecting components. The split structure design allows the air outlet device to be independently adapted and installed on the original vehicle window and rearview mirror system, and is adapted and installed on the vehicle through a suitable connecting component. The connecting component is usually customized according to the specific model and structural characteristics of the vehicle, for example, buckles, screws, card slots, additional shell installation and the like, to ensure that the air outlet device can be tightly and stably fixed on the main and vice driver window triangular area or the rearview mirror, while ensuring that the installation process is simple and easy to operate, without the need for large-scale modification or disassembly of the overall structure of the vehicle. The split structure form installation makes the device convenient to apply to various existing vehicle models, without the need for the vehicle manufacturer to perform complex integrated design at the production stage, providing a simple and effective post-upgrade solution for the vehicles already on the road. Vehicle owners can choose to install according to their own needs, improve the driving safety and comfort of the vehicle in bad weather, and do not have to face the problem of blocked driving vision due to insufficient original vehicle configuration.

[0079] The installation of the air outlet device on the window triangular area and the rearview mirror can accurately remove water mist, frost and snow from the two key parts of the window and the rearview mirror, directly solving the problem of the area with the greatest impact on the driver's vision in bad weather. Compared with the traditional whole vehicle heating or ventilation method, it is more energy-efficient and can quickly and effectively improve the driver's vision, reduce the risk of traffic accidents caused by poor vision, and improve the level of road traffic safety.

[0080] When installed, the air supply device, the main exhaust pipe, the branch exhaust pipe and the pressure air pump can be installed as additional accessories in the internal space of the front compartment of the vehicle, and are installed in cooperation with a suitable wiring arrangement and connected to the corresponding air outlet device.

[0081] When the vehicle needs to use the water mist defrosting and snow removing device in rainy and snowy weather, the positive pressure wind generated by the air supply device is transmitted to the main and vice driver window glass air outlet devices installed in the triangular area of the vehicle window and the rearview mirror air outlet device on the rearview mirror through the main exhaust pipe and the branch exhaust pipe. For the main and vice driver window glass air outlet devices, the vertical arrangement and the inclined angle of the vehicle window air outlet can blow the high-speed cold / hot air flow obliquely to the lower and front local area of the vehicle window glass (between the straight line direction formed by the rearview mirror and the head area of the driver's seat), which can quickly remove the water droplets, mist, frost or snow on the surface of the vehicle window through the scouring and heat transfer effect of the air flow, and restore the clear view of the vehicle window. For the rearview mirror air outlet device, the rearview mirror air outlet on the eaves, left eaves and right eaves of the rearview mirror shell blows the high-speed cold / hot air flow to the rearview mirror surface at a specific inclined angle, which also effectively removes various obstructions on the mirror surface by using the impact force and temperature effect of the air flow, so as to ensure that the driver can clearly observe the situation behind the vehicle. In this embodiment, the main and vice driver window glass air outlet devices and the rearview mirror air outlet device are not necessarily installed at the same time, and only one of them can be installed.

[0082] It should be understood that the above specific embodiments of the utility model are only used for illustrative or explanatory purposes of the principles of the utility model, and do not constitute a limitation on the utility model. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the utility model shall be included in the protection scope of the utility model. In addition, the appended claims of the utility model are intended to cover all changes and modifications falling within the scope and boundary of the appended claims, or the equivalent forms of such scope and boundary.
