Description
Technical Field
The invention relates to the technical field of automobile accessories, in particular to an anti-splashing device for an automobile rear window and a working method thereof.
Background
According to the difference of internal space separation, modern cars are mainly divided into two-compartment cars and three-compartment cars, wherein a luggage compartment and a passenger compartment are combined into a whole at the rear of a handlebar of the two-compartment car, so that the structure is more compact, the length of the whole car is shorter, a driver can conveniently back up and enter a garage, and the controllability is better.
However, the two-compartment vehicle has a disadvantage that, as shown in fig. 1, the front wind is divided into an upper airflow 1 and a lower airflow 2 when viewed from the side during the driving process, wherein the upper airflow 1 flows toward the rear of the vehicle after flowing through the wind wing on the top of the trunk lid 3. The lower airflow 2 flows from the bottom of the vehicle, flows through the lower side of the trunk, and then flows to the rear of the vehicle. Since the trunk lid 3 of the traveling two-compartment car is in a closed state and is more vertical than the tail of the three-compartment car, the upper airflow 1 and the lower airflow 2 cannot be merged at one position at the tail of the car, and an area with a slow air flow rate is formed at the position adjacent to the front rear side of the trunk lid 3, the air pressure of the area is lower than the atmospheric pressure, and a negative pressure area 4 is formed. As shown in fig. 2, when the automobile is driven in rainy days, water 5 thrown by the rear wheel forms water mist 6 after colliding with parts at the bottom of the automobile, and water drops in the water mist 6 partially drift towards the rear of the automobile, and the other part of the water drops enters the negative pressure zone 4 and flows along the negative pressure zone 4 to the rear window glass 7. However, since these water droplets usually contain particulate matter such as dust, muddy water is easily attached to the rear window 7 and interferes with the driver's view of the rear window 7. Although the rear window of the existing two-compartment car is provided with the rear windscreen wiper, the rear windscreen wiper can be used for timely scraping muddy water. But the wearing and tearing and the ageing of back wiper adhesive tape can accelerate to the particulate matter that mix with in the muddy water, shortens the life-span of back wiper adhesive tape, and then increases the cost of wiper change nursing, and the in-process that the water droplet of doping muddy water is scraped off through the wiper is difficult to thoroughly clean up, easily causes the fuzzy effect of back window glass, and the back vision effect is not good.
Therefore, it is necessary to design a splash-proof device for the rear window of the automobile, and to prevent muddy water thrown from the rear wheel from splashing onto the rear window glass by a reasonable and effective control method, so as to ensure that the driver has a clear view when looking backwards through the rear window glass 7, and improve the driving safety.

Detailed Description
The following examples further illustrate the present invention but are not to be construed as limiting the invention. Modifications and substitutions to methods, procedures, or conditions of the invention may be made without departing from the spirit of the invention.
Example one
When the two-compartment vehicle runs under the rainy road condition, in order to avoid that a large amount of water mist with silt particles splashed by rear wheels splashes on the rear window glass 7 in the running process to influence the view field of backward observation of a driver, the embodiment provides the automobile rear window anti-splashing device, the specific structure of which is shown in fig. 3-4, the automobile rear window anti-splashing device disclosed in the embodiment mainly comprises wind wings 8 movably connected with the top of a trunk cover 3 and a wind guide plate 9 movably arranged on the trunk cover 3 and positioned at the lower part of the rear window glass 7, and the wind wings 8 and the wind guide plate 9 share a bilateral symmetry plane with the vehicle body and the trunk cover 3.
Compared with the design that the wind wings on the existing automobile are fixedly installed at the top of the trunk lid 3, in the embodiment, the wind wings 8 are designed to be of a structure capable of horizontally moving relative to the automobile body along the front-back direction of the automobile, the driving cylinders I10 are arranged in the top of the trunk lid 3, in order to guarantee the moving stability of the wind wings 8, if only one driving cylinder I10 is arranged, the driving cylinder I10 can be selectively arranged at the position of the bilateral symmetry plane at the top of the trunk lid 3, a plurality of driving cylinders I10 can also be symmetrically arranged along the width direction of the automobile body by taking the bilateral symmetry plane of the trunk lid 3 as a reference, and the wind wings 8 are fixedly connected with the end parts of the piston rods of the driving cylinders I10 so as to horizontally move along the front-back direction of the automobile. In the initial position, the wind wings 8 are pressed against the top of the boot lid 3.
A second driving cylinder 11 and a third driving cylinder 12 are arranged inside the trunk lid 3 positioned at the inner side of the air deflector 9, the upper end of the inner side of the air deflector 9 is fixedly connected with the end part of a piston rod of the second driving cylinder 11, the lower end of the inner side of the air deflector 9 is fixedly connected with the end part of a piston rod of the third driving cylinder 12, in order to ensure the stability of the movement of the air deflector 9 and the arrangement mode of the first driving cylinder 10, when only one second driving cylinder 11 and one third driving cylinder 12 are arranged, the air guide plate can be selectively arranged at the position of the bilateral symmetry plane of the trunk lid 3, a plurality of second driving cylinders 11 are symmetrically arranged along the width direction of the vehicle body by taking the bilateral symmetry plane of the trunk lid 3 as a reference and are connected with the upper end of the inner side of the air guide plate 9, a plurality of third driving cylinders 12 are arranged and are connected with the lower end of the inner side of the air guide plate 9, and the air guide plate 9 can also horizontally move along the front and back directions of the vehicle under the synchronous pushing action of the second driving cylinders 11 and the third driving cylinders 12.
The position of the trunk lid 3 corresponding to the air deflector 9 is provided with an air deflector accommodating groove 13 matched with the shape of the air deflector, and in the initial position, the air deflector 9 is completely arranged in the air deflector accommodating groove 13, and the outer side surface of the air deflector is positioned on the same smooth surface with the outer surface of the trunk lid 3, so that the appearance is kept consistent, the integral aesthetic degree is improved, and the convenience of a driver for opening and closing the trunk lid 3 is improved.
The first driving cylinder 10, the second driving cylinder 11 and the third driving cylinder 12 used in this embodiment may be pneumatic cylinders or hydraulic cylinders, and are not limited when specifically selected, as long as the wind wing 8 and the wind deflector 9 can move in the horizontal direction, and the three driving cylinders are connected with the microcontroller in the vehicle through a wire harness to open and close.
As shown in fig. 5-6, when the piston rods of the first driving cylinder 10, the second driving cylinder 11 and the third driving cylinder 12 extend outward, the wind wing 8 and the wind deflector 9 move horizontally from the initial position in a direction away from the trunk lid 3, and the distance between the wind wing 8 and the wind deflector 9 after extending horizontally and the adjacent side of the trunk lid 3 is 5-10cm, so that a part of the top airflow 1 of the roof flows to the lower side of the wind deflector 9 after passing through the gap between the wind wing 8 and the trunk lid 3, the outer surface of the rear window glass 7 and the gap between the wind deflector 9 and the trunk lid 3 in sequence, and then flows toward the rear of the vehicle. As shown in fig. 5, at this time, the whole negative pressure region 4 at the tail of the vehicle is divided into two parts, namely a first negative pressure region 14 located behind the air deflector 9 and a second negative pressure region 15 located below the air deflector 9 and outside the rear anti-collision beam 16. As shown in fig. 6, the mist 6 thrown out by the rear wheel cannot pass through the second negative pressure region 15 and reach the first negative pressure region 14, because the air flow passes between the two negative pressure regions, the water mist 6 is blocked from passing between the two negative pressure regions. The reduction of the negative pressure zone and the change of the position thereof make it impossible for the water mist thrown out by the rear wheel to reach the rear window 7.
It is noted that the trunk lid 3 of the two-compartment automobile is inclined because the upper end thereof is provided with the rear window 7, whereas the lower end of the trunk lid 3 is generally close to being perpendicular to the ground in the closed state. There is an outwardly convex region at the transition between the upper and lower ends of the trunk lid 3. After the air deflector 9 is received in the air deflector receiving groove 13, the outer side surface thereof and the outer side surface of the remaining portion of the trunk lid 3 should be kept smooth and snug for the sake of appearance. However, if the length of the air deflector 9 is short, the lower end part does not cover the outward convex area on the trunk lid 3, as shown in fig. 9, the airflow flows out from the lower side of the air deflector 9 along the tangential direction of the bottom of the air deflector 9 after passing through the gap between the air deflector 9 and the trunk lid 3, the top of the formed negative pressure area two 15 is closer to the trunk lid 3, the water mist 6 thrown out by the rear wheel more easily passes through the negative pressure area two 15 to splash onto the trunk lid 3, the polluted area of the trunk lid 3 is large, and the subsequent cleaning cost is increased.
To further solve this problem, the present embodiment proposes a preferable solution, as shown in fig. 10, the height of the air deflector 9 can be designed to be larger, so that the lower end of the air deflector covers the outward convex transition position of the trunk lid 3 from the outside, the lower end of the air deflector 9 also presents an outward convex area 18 matched with the shape of the trunk lid 3, air flows out from the lower side of the air deflector 9 along the tangential direction of the bottom of the air deflector 9 after passing through the gap between the air deflector 9 and the trunk lid 3, and the air deflector 9 has the outward convex area 18, the tangential direction of the bottom of which is closer to the rear impact beam 16, so that the air flow coming out from the lower side of the air deflector 9 is closer to the rear impact beam 16, the top of the second negative pressure region 15 is further away from the trunk lid 3, and the top of the second negative pressure region 15 is lower due to the larger height of the air deflector 9 in fig. 10, and the volume of the second negative pressure region 15 is smaller and is completely located at the rear side of the rear impact beam 16.
As can be seen from comparing fig. 9 and 10, the above two-point improvement in fig. 10 has the technical effect that the water mist 6 thrown out by the rear wheel is less likely to splash onto the trunk lid 3, and particularly in fig. 10, because the second negative pressure region 15 is completely located on the rear impact beam 16 side of the lower side of the trunk lid 3, the water mist 6 splashed during driving only reaches the impact beam 16 and does not reach the trunk lid 3, so that the outer surface of the trunk lid 3 is kept clean.
Example two
As shown in fig. 7-8, this embodiment differs from the first embodiment in that: the central lines of the second driving cylinder 11 and the third driving cylinder 12 which are correspondingly arranged in the longitudinal direction are located in the same vertical plane, and the end parts of the piston rods of the second driving cylinder 11 and the third driving cylinder 12 are not fixedly connected with the air deflector 9 any more, but are respectively hinged with the air deflector 9, so that the air deflector 9 can deflect relative to the piston rods at a corresponding angle.
When the air deflector 9 is in an extended state, the extension distance of the second driving cylinder 11 is shorter than the extension distance of the third driving cylinder 12, the outward extension distance of the piston rod of the second driving cylinder 11 is 2-5cm, and the outward extension distance of the piston rod of the third driving cylinder 12 is 8-12cm, so that the air deflector 9 is in an inclined state as shown in fig. 7, and the upper end of the air deflector 9 is close to the air deflector accommodating groove 13 or is positioned in the accommodating groove, and the lower end of the air deflector 9 is far away from the air deflector accommodating groove 13. At this time, a part of the airflow on the roof of the vehicle flows to the lower side of the air deflector 9 after sequentially passing through the gap between the wind wing 8 and the trunk lid 3, the outer surface of the rear window glass 7 and the outer surface of the air deflector 9, and then flows to the rear of the vehicle. Since the air flow passes through the whole outside of the trunk lid 3, the negative pressure region 4 which originally covers the outer surface of the trunk lid 3 in a large area is reduced to a negative pressure region three 17 in fig. 7, and the negative pressure region three 17 is located below the air deflector 9 and outside the rear impact beam 16. At this time, the negative pressure region is narrowed and the position thereof is changed so that the mist 6 thrown out by the rear wheel cannot reach the rear window 7.
In order to keep the outer surface of the trunk lid 3 clean, in accordance with the preferred embodiment disclosed in the first embodiment, the height of the air deflector 9 is preferably designed to be greater in this embodiment, so that the lower end of the air deflector 9 covers the outward transition position of the trunk lid 3 from the outside, and the lower end of the air deflector 9 also presents an outward convex region 18 matched with the shape of the trunk lid 3, as can be seen from comparing fig. 11 and 12, since the air deflector 9 in fig. 12 has the outward convex region 18, the lower end tangential direction of the air deflector 9 is closer to the rear impact beam 16, and the air flow flowing out from the lower end of the air deflector 9 is closer to the rear impact beam 16, so that the top of the negative pressure region three 17 is further away from the trunk lid 3. Meanwhile, due to the fact that the height of the air deflector 9 in the figure 12 is larger, the volume of the negative pressure area III 17 is reduced and is completely positioned on one side of the rear anti-collision beam 16, water mist 6 is prevented from splashing on the trunk lid 3, and the outer surface of the trunk lid 3 is kept clean.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. However, the above description is only an example of the present invention, the technical features of the present invention are not limited thereto, and any other embodiments that can be obtained by those skilled in the art without departing from the technical solution of the present invention should be covered by the claims of the present invention.
