Summary of The Invention
Problems to be solved by the invention
However, since the rear checking device of patent document 1 includes the wiper device, there is room for improvement in terms of cost. In addition, since the wiper device generally requires a motor for driving, the installation space increases, and the degree of freedom in design may decrease.
The present invention has been made in view of the above circumstances, and an object thereof is to provide a rear checking device that can suppress cost and improve the degree of freedom in design as compared with the conventional art.
Means for solving the problems
In order to solve the above problems, the rear checking device according to the aspect of the present invention employs the following configuration.
(1) A rear confirmation device (a rear confirmation device 11 of an embodiment) according to one aspect of the present invention is provided on a vehicle body (a vehicle body 3 of an embodiment) of a vehicle (a vehicle 1 of an embodiment) and includes an information acquisition unit (an information acquisition unit 17 of an embodiment) for acquiring information on the rear of the vehicle and recognizing an occupant and a housing (a housing 13 of an embodiment) that houses the information acquisition unit therein, and is characterized in that the housing includes an upper surface (an upper surface 31 of an embodiment) facing the upper side in the vertical direction and a lower surface (a lower surface 33 of an embodiment) facing the lower side in the vertical direction, and inclined portions (inclined portions 45 of an embodiment) inclined at a predetermined angle (a predetermined angle α of an embodiment) are provided at each of a rear end portion of the upper surface and a rear end portion of the lower surface so as to narrow a space between the upper surface and the lower surface from the front of the vehicle toward the rear.
(2) In the rear confirmation device according to the aspect (1), the information acquisition unit may be disposed at a position forward of a rear end of the housing and housed in the housing.
(3) In the rear confirmation device according to the aspect (1) or (2), the predetermined angle of the inclined portion of the upper surface and the predetermined angle of the inclined portion of the lower surface may be set to be substantially the same.
(4) In the posterior confirmation apparatus according to any one of the above (1) to (3), the predetermined angle may be set to 6 ° or more and 7 ° or less with respect to the horizontal direction.
(5) In the rear confirmation device according to any one of the above (1) to (4), the housing may have a pair of side surfaces (a pair of side surfaces 35, 35 in an embodiment described later) that connect the upper surface and the lower surface in the left-right direction of the vehicle, and the pair of side surfaces may be formed flat.
(6) In the rear confirmation device according to any one of the above (1) to (5), the inclined portion may be provided at a position separated rearward from a center of the casing by a predetermined distance in a horizontal direction.
(7) In the rear confirmation device according to any one of the above (1) to (5), the housing may be attached to a side surface of the vehicle body, and the information acquisition unit may be a camera that acquires a captured image of the rear of the vehicle as the information of the rear of the vehicle.
Effects of the invention
According to the aspect (1) described above, the inclined portions are provided at the rear end portion of the upper surface and the rear end portion of the lower surface of the housing, respectively. Thus, when the vehicle is traveling, a vortex flow by the traveling wind is generated in the inclined portion, and therefore raindrops and dust adhering to the inclined portion can be blown off and removed. Therefore, the rear confirmation device according to the first aspect can suppress raindrops and dust from adhering to the information acquisition unit and allow the passenger to recognize the information behind the vehicle by providing the inclined portion in the housing. Thus, for example, compared to the conventional art in which a wiper device is provided, the rear confirmation device according to the first aspect can suppress the cost and make it easy for the passenger to confirm the information behind the vehicle. Further, since the rear confirmation device according to the first aspect does not use a wiper device as in the related art, it is possible to suppress an increase in installation space and to improve the degree of freedom in design.
According to the aspect (2) described above, the information acquisition unit is disposed at a position forward of the rear end of the housing and is housed in the housing. Accordingly, for example, when the vehicle is stopped or traveling at a low speed, raindrops and dust adhering to the inclined portion can be prevented from being screwed into the housing, and therefore, adhesion of raindrops and dust to the information acquisition portion can be prevented. As a result, the rear confirmation device according to the second aspect can improve the degree of freedom in design while suppressing the cost, and can allow the passenger to recognize the information behind the vehicle, as compared with the conventional technology.
According to the aspect (3), the predetermined angle of the inclined portion of the upper surface and the predetermined angle of the inclined portion of the lower surface are set to be substantially the same. Thus, the strength of the vortex formed by the traveling wind generated by the inclined portion of the upper surface and the inclined portion of the lower surface is substantially the same. Therefore, the eddy current formed by the traveling wind generated in the inclined portion can blow off and remove raindrops and dust adhering to the inclined portion on the upper surface and the inclined portion on the lower surface substantially uniformly and efficiently. Therefore, the rear confirmation device according to the third aspect can effectively suppress raindrops and dust from adhering to the information acquisition unit.
According to the aspect (4), it was confirmed through experiments that raindrops and dust can be effectively removed by setting the predetermined angle of the inclined portion to be in the range of 6 ° to 7 ° with respect to the horizontal direction. Therefore, the backward confirmation device according to the fourth aspect can effectively suppress raindrops and dust from adhering to the information acquisition unit.
According to the aspect (5) above, the pair of side surfaces of the case is formed flat. This can suppress the generation of the vortex flow in the portion other than the inclined portion of the housing, and thus can suppress the disturbance of the flow of the vortex flow generated in the inclined portion. Therefore, the eddy current generated in the inclined portion can efficiently blow off and remove raindrops and dust adhering to the inclined portion. Therefore, the rear confirmation device according to the fifth aspect can effectively suppress raindrops and dust from adhering to the information acquisition unit.
According to the aspect (6), since the inclined portion is provided at the position separated rearward by the predetermined distance from the center of the housing in the horizontal direction, the area of the inclined portion can be reduced as compared with the case where the inclined portion is provided at the position forward from the center of the housing in the horizontal direction. As a result, the rear confirmation device according to the sixth aspect can reduce the air resistance in the inclined portion as compared with the case where the inclined portion is provided at a position forward of the center of the housing in the horizontal direction, and therefore can increase the flow velocity of the vortex generated in the inclined portion. Therefore, the rearward confirmation device according to the sixth aspect can effectively suppress raindrops and dust from adhering to the information acquisition unit.
According to the aspect (7), since the housing is attached to the side surface of the vehicle body, the rear confirmation apparatus of the present invention can be applied without giving a sense of incongruity to design as compared with a conventional vehicle including a door mirror. Further, since the information acquiring unit is a camera that acquires a captured image of the rear of the vehicle as information of the rear of the vehicle, the passenger can recognize the information of the rear of the vehicle by a monitor disposed in the vehicle compartment, for example. Therefore, the high-performance rear-view monitor with excellent usability can be provided.

Hereinafter, embodiments of the present invention will be described based on the drawings.
Fig. 1 is a perspective view of a vehicle equipped with a rear confirmation device according to an embodiment of the present invention.
Fig. 2 is a side view of the posterior confirmation apparatus.
In the following description, the front-rear direction is the front-rear direction of the vehicle 1 and coincides with the horizontal direction. The left-right direction coincides with the left-right direction of the vehicle 1. The vertical direction is the vertical direction of the vehicle 1, and coincides with the vertical direction. In the drawings used below, the vehicle front direction is indicated by an arrow FR, the vehicle upper direction is indicated by an arrow UP, and the vehicle left direction is indicated by an arrow LH.
As shown in fig. 1, a rear check device 11 is provided above the left side door 5 of the vehicle 1. The rear confirmation device 11 is used to allow the passenger to recognize information on the rear side of the vehicle 1. The rear confirmation device 11 includes a housing 13, a vehicle body attachment portion 15, and an information acquisition portion 17.
As shown in fig. 2, the housing 13 is formed to extend in the front-rear direction of the vehicle 1. The case 13 is formed in a bottomed cylindrical shape opened rearward. An opening 19 is formed at the rear end of the housing 13.
The vehicle body mounting portion 15 is provided below the housing 13 and is formed integrally with the housing 13. The vehicle body mounting portion 15 fixes the housing 13 to a side surface of the vehicle body 3. Specifically, the vehicle body attachment portion 15 fixes the housing 13 at a position rearward of the pillar, for example, at the upper portion of the left side door 5.
Fig. 3 is a sectional view of the rear end portion of the housing in the front-rear direction.
As shown in fig. 3, the information acquisition portion 17 is provided inside the housing 13. The information acquiring unit 17 is configured to acquire information on the rear side of the vehicle 1 and confirm the information to the passenger.
The information acquiring unit 17 includes a protecting unit 21 and an imaging device 23.
The protection unit 21 protects the imaging device 23 from being damaged by interference between the imaging device 23 and an external article or the like. The protection portion 21 is formed in a plate shape by a material having light transmittance such as an acrylic resin material. The protection portion 21 is disposed inside the housing 13 at a position forward of the rear end of the housing 13. The protection portion 21 is attached to the housing 13 by closing the opening 19 of the housing 13.
The imaging device 23 is disposed in the housing 13 at a position forward of the protection portion 21. The imaging device 23 is a so-called camera having an imaging element such as a CMOS (complementary metal oxide semiconductor) sensor therein, for example, and acquires an image of the rear of the vehicle 1 as information of the rear of the vehicle 1. The imaging device 23 includes a lens 61 and an imaging device body 63. The lens 61 is attached to the rear end of the photographing device body 63. The lens 61 is disposed forward of the protection unit 21. The imaging device main body 63 is connected to a monitor disposed in the vehicle interior.
Fig. 4 is a rear view of the opening of the housing.
As shown in fig. 4, the imaging device 23 is disposed on the left side (vehicle exterior side) of the center portion in the left-right direction inside the housing 13. This makes it possible to acquire information on the left rear side of the vehicle over a wider range than in the case where the imaging device 23 is disposed in the center portion in the left-right direction inside the housing 13.
The imaging device 23 captures information of the rear side through the protection unit 21 and the lens 61, and obtains image data in the imaging device main body 63. The imaging device main body 63 transmits the obtained image data to a monitor inside the vehicle. The monitor converts image data sent thereto from the imaging device main body 63 into an image for display and displays the image on the screen. The passenger can recognize information behind the vehicle 1 by viewing the image displayed on the screen of the monitor.
As shown in fig. 2, the housing 13 of the rear check device 11 includes: an upper surface 31; a lower surface 33; a pair of side faces 35, 35; and a front surface 37.
The upper surface 31 faces the upper side in the vertical direction (vertical direction) of the vehicle 1. The lower surface 33 faces the lower side in the vertical direction (vertical direction) of the vehicle 1. The upper surface 31 and the lower surface 33 are formed along the front-rear direction (horizontal direction) of the vehicle 1. The vehicle body mounting portion 15 described above is connected to the lower surface 33.
Specifically, in the present embodiment, the pair of inclined portions 45, 45 provided at the rear end portion of the upper surface 31 and the rear end portion of the lower surface 33 are provided at positions separated rearward from the center C of the housing 13 by a predetermined distance d in the front-rear direction (horizontal direction). In the present embodiment, the predetermined distance d is set to a length of, for example, about 1/4 to 1/5 of the entire length of the housing 13.
The pair of inclined portions 45, 45 are inclined at a predetermined angle α so as to narrow the space between the upper surface 31 and the lower surface 33 from the front to the rear, in other words, the pair of inclined portions 45, 45 are inclined at a predetermined angle α with respect to the front-rear direction of the vehicle 1 so as to gradually decrease the dimension of the housing 13 in the vertical direction (vertical direction in fig. 2) from the front to the rear, and the predetermined angle α of the inclined portion 45 of the upper surface 31 and the predetermined angle α of the inclined portion 45 of the lower surface 33 are set to be substantially the same.
Here, as a result of experiments in which the angle of the predetermined angle α was changed, the rear confirmation apparatus 11 could confirm that raindrops and dust could be effectively removed by setting the predetermined angle α to 6.5 ° from the experiments, and therefore, considering that there is a manufacturing error of 6.5 °, the predetermined angle α is preferably set to a range of 6 ° to 7 ° with respect to the front-rear direction of the vehicle 1, for example, and experiments for studying the set value of the predetermined angle α and the experimental results thereof with respect to the inclined portion 45 of the rear confirmation apparatus 11 of the present embodiment will be described later.
The portion 51 of the upper surface 31 other than the inclined portion 45 is formed to be flat from the rear toward the front and then inclined downward. The portion 53 of the lower surface 33 other than the inclined portion 45 is formed flat along the front-rear direction of the vehicle 1.
A pair of side surfaces 35, 35 connect the left and right ends of upper surface 31 to the left and right ends of lower surface 33. The pair of side surfaces 35, 35 are formed flat. In other words, the inclined portions are not provided on the pair of side surfaces 35, 35.
Fig. 5 is a diagram illustrating the removal of raindrops and dust by the housing.
Next, the removal of raindrops and dust E by the case 13 of the rear confirmation device 11 according to the present embodiment will be described with reference to fig. 5.
As shown in fig. 5, during traveling of the vehicle 1 (see fig. 1), the traveling wind F flows rearward from the front of the vehicle 1. Raindrops and dust E adhering to the casing 13 are blown off by the traveling wind F and removed from the casing 13. When the vehicle 1 travels, a vortex G is generated by the traveling wind F in the pair of inclined portions 45, 45 of the casing 13. Raindrops and dust E adhering to the pair of inclined portions 45 and raindrops and dust E flying out from positions forward of the pair of inclined portions 45 and adhering to the pair of inclined portions 45 and 45 are blown off by the vortex G and removed from the pair of inclined portions 45 and 45.
Next, an experiment performed to examine the set value of the predetermined angle α and the experimental results thereof will be described with respect to the inclined portion 45 of the rear confirmation apparatus 11 of the present embodiment.
In the experiment, 5 models having different inclination angles of the inclined portion 45 were used for the rear confirmation apparatus 11 of the embodiment. The appearance shape of each model is the same as that of the case 13 of the embodiment. Each mold has an inclined portion similar to the inclined portion 45 of the embodiment. The angles of the inclined portions of the respective models were set to 0 °, 2 °, 4 °, 6.5 °, and 8 °, respectively.
As described above, an experiment relating to the amount of raindrops adhering to the rear surface of each model during running was performed in the following order using 5 models having different angles of the inclined portion.
(1) The colored water droplets were attached to the upper surface of the mold. The water droplets correspond to raindrops and dust.
(2) The model is arranged in the wind tunnel device.
(3) The wind tunnel device is operated to artificially generate the running wind. The wind speed of the running wind is 80 km/h.
(4) And placing the model in the wind tunnel device for a specified time. When a predetermined time has elapsed, the wind tunnel device is stopped, and the model is taken out from the wind tunnel device.
(5) The amount of water droplets adhering to the rear surface of the model was measured. The rear surface of the model corresponds to the protection unit 21 of the information acquisition unit 17 in the embodiment.
Fig. 6 is a graph showing a relationship between an angle of an inclined portion of a model of the rear confirmation device and an adhesion amount of water droplets adhering to a rear surface. The angle shown on the horizontal axis of the graph is the angle of the inclined portion of the model. The amount of water droplets adhering on the vertical axis of the graph is the amount of water droplets adhering to the rear surface of the model. The graph is created based on the amount of water droplets adhering obtained by the above experiment. As shown in the graph of fig. 6, in the case where the angle of the inclined portion in the model is set to 6.5 °, the amount of adhesion of water droplets adhering to the rear surface of the model is the smallest.
From the above experimental results, it can be confirmed that when the predetermined angle α of the pair of inclined portions 45, 45 is 6.5 °, it is most possible to suppress raindrops and dust from adhering to the protective portion 21 of the information acquiring portion 17, and thus, the predetermined angle α of the rear confirmation device 11 of the embodiment is preferably set to a value obtained by adding a manufacturing error to 6.5 °, that is, to a range of 6 ° to 7 ° with respect to the front-rear direction of the vehicle 1, and is most preferably set to 6.5 ° with respect to the front-rear direction of the vehicle 1.
Next, the operational effects of the rearward checking device 11 of the present embodiment will be described.
(1) According to the embodiment, the inclined portions 45 are provided at the rear end portion of the upper surface 31 and the rear end portion of the lower surface 33 of the housing 13, respectively. Thus, when the vehicle 1 travels, the eddy G caused by the traveling wind is generated in the inclined portion 45, and therefore raindrops and dust E adhering to the inclined portion 45 can be blown off and removed. Therefore, the rear confirmation device 11 of the embodiment can prevent raindrops and dust E from adhering to the information acquisition unit 17 and allow the passenger to recognize information behind the vehicle 1 by providing the inclined portion 45 in the housing 13. Thus, the rear confirmation device 11 of the embodiment can make it easier for the passenger to confirm the information behind the vehicle 1 while suppressing the cost, compared to the conventional technique in which a wiper device is provided, for example. Further, since the rear check device 11 of the embodiment does not use a wiper device as in the related art, it is possible to suppress an increase in installation space and to improve the degree of freedom in design.
In addition, according to the embodiment, the information acquiring unit 17 is disposed at a position forward of the rear end of the housing 13 and is housed in the housing 13. This can prevent raindrops and dust adhering to the inclined portion 45 from being caught in the interior of the housing 13, for example, when the vehicle 1 is stopped or traveling at a low speed, and therefore can prevent raindrops and dust from adhering to the information acquiring portion 17. As a result, the rear confirmation device 11 of the embodiment can improve the degree of freedom in design while suppressing the cost, and can make the passenger recognize the information behind the vehicle 1, as compared with the conventional technology.
According to the embodiment, the predetermined angle α of the inclined portion 45 of the upper surface 31 and the predetermined angle α of the inclined portion 45 of the lower surface 33 are set to be substantially the same, whereby the strength of the vortex G formed by the traveling wind generated by the inclined portion 45 of the upper surface 31 and the inclined portion 45 of the lower surface 33 is substantially the same, and therefore, the vortex G formed by the traveling wind F generated by the inclined portion 45 can blow and remove the raindrops and the dust E adhering to the inclined portion 45 of the upper surface 31 and the inclined portion 45 of the lower surface 33 substantially equally and efficiently, and therefore, the rear confirmation device 11 of the embodiment can efficiently suppress the raindrops and the dust E from adhering to the information acquisition portion 17.
According to the embodiment, it can be confirmed through experiments that raindrops and dust E can be effectively removed by setting the predetermined angle α of the inclined portion 45 in the range of 6 ° to 7 ° with respect to the front-rear direction (horizontal direction) of the vehicle 1, and therefore, the rear confirmation device 11 of the embodiment can effectively suppress the raindrops and dust E from adhering to the information acquisition portion 17.
According to the embodiment, the pair of side surfaces 35, 35 of the housing 13 is formed flat. This can suppress the generation of the vortex flow in the portion other than the inclined portion 45 of the housing 13, and thus can suppress the disturbance of the flow of the vortex flow G generated in the inclined portion 45. Therefore, the vortex G generated in the inclined portion 45 can efficiently blow off and remove raindrops and dust E adhering to the inclined portion 45. Therefore, the rear confirmation device 11 of the embodiment can effectively prevent raindrops and dust E from adhering to the information acquiring unit 17.
According to the embodiment, since the inclined portion 45 is provided rearward of the center C of the housing 13 by the predetermined distance d in the front-rear direction (horizontal direction) of the vehicle 1, the area of the inclined portion 45 can be reduced as compared with a case where the inclined portion is provided forward of the center C of the housing 13 in the front-rear direction (horizontal direction) of the vehicle 1. Thus, compared to the case where the inclined portion is provided at a position forward of the center C of the housing 13 in the front-rear direction (horizontal direction) of the vehicle 1, the rear confirmation device 11 of the embodiment can reduce the air resistance at the inclined portion 45, and therefore can increase the flow velocity of the vortex flow G generated at the inclined portion 45. Therefore, the rear confirmation device 11 of the embodiment can effectively prevent raindrops and dust E from adhering to the information acquiring unit 17.
According to the embodiment, since the housing 13 is attached to the side surface of the vehicle body 3, the rear confirmation device 11 of the embodiment can be applied without giving a sense of incongruity to design as compared with a conventional vehicle including a door mirror. Since the information acquiring unit 17 is a camera that acquires a captured image of the rear of the vehicle 1 as information of the rear of the vehicle 1, the information of the rear of the vehicle 1 can be recognized by the passenger using a monitor disposed in the vehicle cabin, for example. Therefore, the high-performance rear check device 11 with good usability can be obtained.
The technical scope of the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the scope of the present invention.
In the embodiment, the imaging device 23 is adopted as the information acquisition unit 17. In contrast, for example, a rear view mirror may be used as the information acquiring unit 17 instead of the imaging device 23, or both the imaging device 23 and the rear view mirror may be used.
In addition, the components in the above-described embodiments may be replaced with known components as appropriate within a range not departing from the gist of the present invention.
Industrial applicability
According to the above-described rear check device, the degree of freedom in design can be improved while suppressing the cost as compared with the conventional art.
