Description

Quick defogging defrosting ice and snow device for main and auxiliary driving window glass and rearview mirror

Technical Field

The utility model relates to the technical field of automobile assistance, mainly relates to technical improvement of vehicle windows and rearview mirrors, and in particular relates to a device for rapidly removing water mist, defrosting and ice and snow for a main driving window glass and a secondary driving window glass and a rearview mirror.

Background

In the current automobile use scene, weather conditions such as rainy days, foggy days, ice and snow days bring a plurality of potential safety hazards to the driving of the vehicle. When these days are encountered, the left and right rear view mirrors, the main and sub driving window glass, and the front and rear windshields of the vehicle often occur to be attached by raindrops, fogged, frosted, frozen, or covered by snow, which makes it difficult for the driver to clearly observe the left and right and front and rear conditions of the vehicle. Particularly, when the vehicle needs to be operated in a road combination, a turning and the like, the surrounding traffic conditions cannot be accurately judged because the rearview mirror cannot be seen clearly, so that the risk of traffic accidents is greatly increased.

For the existing automobile configuration, although the rearview mirrors of part of vehicles have heating functions, the heating mode has obvious defects that the heating speed is too slow, the actual use effect is poor, the functions of rapid water removal, defogging, defrosting, deicing and snow removal cannot be effectively realized at all, and the driving safety requirements in rainy and snowy days are difficult to meet. In recent years, some new energy vehicle enterprises try to popularize electronic rearview mirrors as optional mounting configurations of vehicles. However, electronic rearview mirrors also have a series of problems. Firstly, the cost is high, and the minimum cost is 0.5-1.5 ten thousand yuan, which clearly increases the purchase cost of the consumers. Second, from a design perspective, electronic rearview mirrors are relatively slim and do not meet the aesthetic preferences of most consumers. Furthermore, the cost of post-repair of electronic rear-view mirrors is also quite high, which makes it prohibitive for many consumers. More importantly, the electronic rearview mirror only solves part of the problems of the traditional rearview mirror, and still cannot solve the problems of defogging, defrosting, deicing and snow removing of front and rear windshields in rainy and snowy days. Even under certain circumstances, rainwater on the vehicle rearview mirror can be dried through modes such as heating, but at this time, water drops, snow or ice often still exist on the main and auxiliary driving windows, and these still can shelter from the sight that the driver observed the rearview mirror, and the traffic situation that leads to the driver to be unable to know the vehicle periphery comprehensively also can't solve the driving potential safety hazard under the rain and snow weather.

Detailed Description

The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

Embodiment 1 description of the use process of a device for rapidly removing water mist, defrosting and ice and snow on a main and auxiliary driving window glass:

scene one early morning in cold winter

In the early morning of a cold winter, the outdoor temperature is extremely low, the vehicle is parked overnight, a layer of thick frost is formed on the windows of the main driving window and the auxiliary driving window, the sight of the rearview mirror 2 is almost completely blocked by a driver, the vehicle is seen from the inside to the two sides, and the road and the surrounding environment outside the vehicle and the scene in the rearview mirror 2 can not be seen;

In the using process, as shown in fig. 3 and 7, after a vehicle owner enters the vehicle to start the vehicle, the vehicle window ice and snow removing device of the embodiment is started. The air flow supply device 1 is started rapidly, the heat exchanger starts to absorb the heat energy generated by the engine according to a program preset by the vehicle control system or a heating mode which is manually selected by a vehicle owner, the heat exchanger starts to absorb the heat energy generated by the engine, and the heated air is sucked by the independent fan and conveyed to the branch exhaust pipe 12 through the main exhaust pipe 11. The branch gauntlet 12 directs the flow of hot air to the window outlet 3 in the mirror base 31. The window openings 3 are arranged vertically with an inclination angle, from which the hot air flows are blown obliquely towards the lower front partial region of the window pane, i.e. the portion between the rear view mirror 2 and the straight line direction of the main driving seat head region. As the hot gas flow is concentrated toward the critical area, the frost begins to melt rapidly and is blown away by the hot gas flow. In a short period of several minutes, the window glass that was originally completely covered with frost becomes clear, and the driver can clearly see the conditions outside the vehicle, including the visible range of the rear view mirror 2, so that the vehicle can be started safely and driven out of the parking space. The situation that the vehicle runs in snowy weather and the snow falls on the vehicle window is similar to the use process in the scene.

Scene two, driving in rain

Conditions before use: the vehicle runs in the rainy weather, and the rainwater is constantly beaten on main and auxiliary driving window glass, and although window glass has certain inclination, the rainwater still has formed one deck water film on the door window, has seriously influenced the sight that the driver observed rearview mirror 2 through the door window, especially when the vehicle turns or changes the way, and the driver can't accurately judge the position of surrounding vehicle, has the potential safety hazard.

In the using process, as shown in fig. 3 and 7, after a driver of the new energy automobile notices that the sight is blocked in the driving process, the driver presses a button in the automobile for controlling the device, and the driver selects to access a heat pump air conditioner to provide a hot air mode or controls the automobile to execute the function through vehicle-mounted voice. At this time, the cold and hot air blower rotates at a high speed, and the positive pressure hot air generated by the cold and hot air blower through the electric heating device reaches the window air outlet 3 through the main exhaust pipe 11 and the branch exhaust pipe 12. The hot air flow blows to the window glass at a specific inclined angle, so that the rainwater on the window is quickly evaporated and blown away. Along with the continuous blowing of hot air flow, the water film on the window glass quickly disappears, the sight of a driver becomes clear, the scene in the rearview mirror 2 can be clearly seen, the safe driving in the driving process in a rainy day is ensured, the operations such as turning, lane changing and the like are smoothly completed, and the traffic accidents possibly caused by poor sight are avoided.

Embodiment 2 description of the use process of the device for quickly removing water mist and ice and snow from the rearview mirror:

Scene one, driving after snowfall in winter

In the situation before use, after snowfall overnight, a thick layer of snow is accumulated on the left rearview mirror 2 and the right rearview mirror 2 of the vehicle, and a layer of thin ice is condensed on the mirror surface due to the temperature difference between the temperature in the vehicle and the low temperature outside, so that the sight of the rearview mirror 2 is completely blocked, a driver cannot observe the situation behind the vehicle through the rearview mirror 2, and under such a situation, the driving of the vehicle has great safety risks both in changing lanes and reversing.

The use process is that as shown in figures 1, 2 and 7, the vehicle owner starts the vehicle after getting on the vehicle, and simultaneously opens the ice and snow defrosting device of the rearview mirror 2. The air flow supply device 1 starts to operate, and the air flow supply device is supposed to be connected with an engine heat source to heat the air flow (the engine gradually rises after being started, so that a stable heat source can be provided for the device). After being heated, the air is transferred to the branch duct 12 through the main duct 11, and then to the mirror air outlet device in the housing 21 of the mirror 2. The 3 air outlets (obliquely inwards arranged) on the eaves 23 on the rearview mirror 2 and the 2 air outlets (obliquely inwards inclined as well) on the left and right eaves 25 respectively start to blow out the high-speed hot air flow. The hot air flows blow to the mirror surface of the rearview mirror 2 along the respective inclined planes, the transverse narrow-mouth air flows of the upper eave 23 are downwards expanded, snow and ice layers can be quickly melted, melted water is blown dry, and the vertical narrow-mouth air flows of the left eave 25 and the right eave 25 are downwards expanded in an inclined manner, so that snow and ice residues at the edges and corners of the mirror surface are effectively removed from the side surfaces. After only a few minutes, the mirror surface of the rearview mirror 2 becomes clear and clean, so that a driver can clearly see the conditions of the rear vehicle and the road, can drive the vehicle to get on the road with confidence, smoothly turns, changes the road and the like, and ensures the driving safety.

Scene two, rain weather driving

In the condition before use, the vehicle runs in the rainwater, a large amount of raindrops are continuously hit on the mirror surface of the rearview mirror 2, and even if the rearview mirror 2 has a certain rainproof design, the mirror surface is rapidly covered by the rainwater due to the fact that the rearview mirror 2 is hit by the rainwater, a layer of water curtain is formed, the rear view is blurred, a driver is difficult to accurately judge the position and the running state of the rear vehicle, and serious threat is brought to running safety.

In the using process, as shown in figures 1, 2 and 7, after the driver perceives that the sight of the rearview mirror 2 is blocked, the device is started immediately, and a mode of supplying cold air by accessing a heat pump air conditioner is selected (the cold air can quickly reduce the temperature of rainwater on a mirror surface, so that the cold air is easier to blow off and evaporate). The high-speed positive pressure cold air generated by the air flow supply device 1 reaches the rearview mirror air outlet 22 through the calandria system. The cold air flow blown out from the air outlets on the upper and left and right eaves 23 and 25 is blown to the mirror surface along the inclined surface, so that the rainwater on the mirror surface is quickly blown out into small water drops, and the evaporation of the small water drops is accelerated. Under continuous cold air blowing, the definition of the mirror surface of the rearview mirror 2 gradually recovers, and a driver can clearly see key signals such as a turn light, a brake light and the like of a rear vehicle, so that the lane changing time and the safety distance between the rear vehicle can be accurately mastered, and the safe driving in heavy rain weather is ensured.

Embodiment 3. A use process of the device for rapidly removing water mist, defrosting and ice and snow on the glass of a main driving window and a secondary driving window is described in the following steps:

Before the vehicle starts, the vehicle is parked outdoors, the window glass and the rearview mirror 2 are sprayed by rainwater, raindrops are fully distributed, and the sight is seriously blocked.

The vehicle is started when the driver enters the vehicle and starts the engine of the vehicle. At this time, the electronic system of the vehicle enters an operable state after completing the self-test.

And (3) starting a rain removing mode, namely enabling a driver to find out a control option of the water mist and ice and snow removing device through a control interface of a console in the vehicle, and selecting the rain removing mode suitable for rainy days (assuming that a cold air mode is provided for accessing a heat pump air conditioner).

The center console sends a signal to the cold and hot air blower to control the cold air blower to start the cold air output function, and simultaneously sends a starting signal (if any) to the pressurized air pump 13 to improve the flow speed and the air quantity of the air flow and enhance the rain removal effect.

The cold and hot air blower rotates at high speed, the positive pressure cold air generated is transmitted to the branch calandria 12 through the main calandria 11, and the branch calandria 12 respectively transmits the cold air to the rearview mirror air outlet device in the shell 21 of the left rearview mirror 2 and the rearview mirror 2, and the connection part between the main driving window glass and the auxiliary driving window glass and the rearview mirror 2 and the window air pipes arranged along the top edge of the window frame and the two side edges of the window frame of the main driving window and the auxiliary driving window in a continuous and integrated mode.

Actual effect in the rain removal process:

The rear view mirror 2 removes rain, and as shown in fig. 1, 2 and 7, the rear view mirror air outlets 22 on the left and right eaves 24 and 25 and on the rear view mirror 2 start to work, and high-speed cold air is blown out at a specific inclination angle. The air outlets which are obliquely arranged in 4 oblique directions on the upper eave 23 form an air outlet range which is expanded downwards by the air flow with a transverse narrow opening, and the air outlets which are obliquely inclined inwards in 3 directions on the left eave 25 and the right eave 25 form an air outlet range which is expanded downwards by the air flow with a vertical narrow opening, and the cold air flows are blown to the mirror surface of the rearview mirror 2 rapidly to blow down the raindrops on the mirror surface into small water drops and accelerate the evaporation of the small water drops, so that a driver can clearly see the image in the rearview mirror 2, accurately judge the situation behind the vehicle, and provide clear visual field guarantee for lane changing, turning and other operations.

The main and auxiliary driving window glass removes rain, as shown in fig. 3 and 7, at the main and auxiliary driving window glass, a window air outlet 3 which is vertically arranged and provided with an inclined angle blows high-speed cold air flow obliquely to a partial area (positioned between the straight line direction formed by the rearview mirror 2 and the head area of the main driving position) of the window glass, and meanwhile, a window air pipe arranged along a window frame blows cold air flow at a high speed to the whole window area. The cold air enables raindrops on the window glass to be blown away and evaporated rapidly, clear vision of a driver on the periphery of the window and the rearview mirror 2 is recovered, the driver can be ensured to clearly observe traffic conditions around the vehicle, and traffic accidents caused by the blocking of the vision are avoided.

After the use, when the rain potential is reduced or the sight lines of the vehicle window and the rearview mirror 2 are restored to be clear, the driver can operate the device again through the central console, the cold and hot air blower and the pressurizing air pump 13 (if any) are closed, the device stops working, and the next use requirement is waited.

In the embodiment 4, the air outlet device of the main driving window glass and the auxiliary driving window glass is a window air pipe which is continuously and integrally arranged along the top edge of a window frame and two side edges of the window frame of the main driving window and the auxiliary driving window, as shown in fig. 4 and 5, the window air pipe is connected with a branch pipeline of the calandria, and can blow cold/hot air flow at high speed in the whole window area, the window air pipe is integrally designed for a window rubber strip 4 at the outer side of the window, the window rubber strip 4 at the outer side is internally provided with an air pipe, and a plurality of air outlets 41 are formed and are arranged and installed along the window frame.

The use case is that the device is used and operated in snowy weather:

During the running process of the vehicle, a layer of snow or even ice is accumulated on the windows of the main driving window and the auxiliary driving window, so that the observation of the outside condition of the vehicle by a driver is seriously affected, and the sight is seriously blocked.

The snow and ice removal mode is turned on (using the engine heat source as an example):

The driver finds the control options of the device through the control interface of the console in the vehicle, and selects a mode of heating by using the heat source of the engine.

The center console sends an opening signal to an electric valve positioned on a heat exchanger beside an engine cylinder or an exhaust pipe, so that air sucked by the independent fan is heated through the heat exchanger. Meanwhile, if the pressurized air pump 13 is provided, the device can be started to improve the flow speed and the air quantity of the air flow and enhance the snow and ice removing effect.

The heated and pressurized air is transmitted to the branch calandria 12 through the main calandria 11, the branch calandria 12 transmits the hot air to the window air pipes which are arranged along the top edge of the window frame of the main and auxiliary driving window and the two side edges of the frame in a continuous and integrated mode, the window air pipes are integrally designed by window rubber strips 4 on the outer side of the window, a plurality of air outlets 41 are arranged in the rubber strips, and hot air can be blown from the air outlets 41 to the window surface in a concentrated mode in three directions in a mode of surrounding the window.

The actual effect in the process of removing snow and ice:

The hot air is blown out at high speed from the air outlet 41 on the window strip 4 toward the entire window area. For snow on the car window, hot air flow firstly enables the surface of the snow to start to melt, and along with continuous hot air blowing, the snow gradually flows down in water, and for thin ice on the car window, hot air can rapidly enable the ice to heat up and melt, and then the ice is dried. In a few minutes, the window glass originally covered by snow and ice becomes clear and transparent gradually, a driver can clearly see the road outside the vehicle, traffic signs and the conditions of surrounding vehicles and pedestrians, the safety of driving on snow is greatly improved, the surrounding environment can be accurately judged no matter whether the vehicle starts, runs or turns, stops and other operations, and traffic accidents caused by sight obstruction are avoided.

After the vehicle window glass is completely cleared of snow and ice, the driver can operate the vehicle window glass again through the central console after the vision is clear, and the device stops working and waits for the next use requirement when the independent fan and the electric valve are closed and the engine heat source mode and the pressurizing air pump 13 (if any) are adopted.
