Disclosure of Invention
Problems to be solved by the invention
In recent years, there is a trend toward the adoption of advanced driving assistance systems for straddle-type vehicles, which use in-vehicle information acquisition devices such as in-vehicle cameras and millimeter wave radars. In the case where the in-vehicle information acquisition device is mounted on a straddle-type vehicle, since the housing is required to be light in weight and to have a shape of a vehicle design, the use of a resin member is generally considered. However, in a straddle-type vehicle, there are cases where the vehicle height is relatively low, and there are many chances of collision with flying objects such as stones and sand, and a resin member having a lower strength than a windshield is a severe environment. Although some resin members are relatively resistant to impact and deterioration by sunlight, covering the entire in-vehicle information acquisition device with such a resin material for waterproofing results in a significant cost increase.
The invention aims to provide a vehicle-mounted information acquisition device housing which realizes the protection of a vehicle-mounted information acquisition device at low cost.
Technical means for solving the problems
In order to solve the above-described problems, the present invention provides an in-vehicle information acquisition device housing for housing an in-vehicle information acquisition device therein, the in-vehicle information acquisition device housing including: a window portion to which a first resin member that transmits electromagnetic waves from the outside is fixed so that information can be obtained by the in-vehicle information obtaining device; and a second resin member provided in front of the window portion, separate from the first resin member, and transmitting electromagnetic waves from the outside so as to be able to obtain information by the in-vehicle information acquisition device.

Detailed Description
Next, embodiments of the present invention will be described with reference to the drawings.
Example 1
The in-vehicle information acquiring apparatus housing according to embodiment 1 will be specifically described with reference to fig. 1 and 2. Fig. 1 is a front perspective view showing a schematic configuration of a housing of an in-vehicle information acquiring apparatus according to embodiment 1, and fig. 2 is a sectional view A-A of fig. 1. In the following description, unless otherwise specified, the direction in which the vehicle travels is defined as the forward direction. The in-vehicle information acquiring device may be, for example, a camera that shoots the front of the vehicle, or another device such as a millimeter wave radar.
The cover main body 1 has a box-like container shape covering the periphery of the in-vehicle information acquiring device 2, and is continuously integrally formed of the first resin member as the same material, so that it is possible to prevent moisture from entering from the outside of the cover main body 1. Further, the cover main body 1 does not have to be constituted by only the first resin member, and does not prevent the use of other members in the portion not related to the waterproof property. In addition, since the transparent material that transmits electromagnetic waves from outside the cover main body 1 is used for the first resin member, information acquisition from the vehicle front side of the in-vehicle information acquisition device 2 becomes possible. However, the outer surface side of the first resin member is coated so that the interior of the cover main body 1 cannot be seen through in a region of the first resin member outside the window portion 1a including the field of view of the in-vehicle information acquiring apparatus 2. In addition, as an example of a specific material of the first resin member, polycarbonate may be used, but is not limited thereto.
In particular, since the vehicle-mounted information acquisition device housing mounted in the straddle-type vehicle as in the present embodiment has a low vehicle height, there is a high possibility of contact with the flying object, and it is difficult to use an expensive material such as a windshield, as described above, the housing main body 1 is made of resin. Here, in the present embodiment, the second resin member 3 is provided in front of the cover main body 1 so as to cover at least the front of the field of view of the in-vehicle information acquisition device 2, so as to prevent damage and deterioration of the cover main body 1, in particular, the first resin member in the window portion 1 a. The second resin member 3 is fixed to the front surface side of the cover main body 1 using the adhesive 5, but the position where the adhesive 5 is provided is preferably set outside the field of view of the in-vehicle information acquisition device 2 (the information acquisition area 4 shown in fig. 2) so as not to affect the information acquisition.
Here, since the waterproof performance with respect to the in-vehicle information acquiring apparatus 2 is ensured by the cover main body 1, the waterproof performance at the time of fixing the second resin member 3 to the cover main body 1 can be disregarded. Thus, in the present embodiment, the fixing position of the second resin member 3 with the cover main body 1 is defined at the upper and lower sides 2, not the entire periphery. Therefore, in the case where damage or the like occurs to the second resin member 3, the second resin member 3 can be detached while maintaining the water resistance to the in-vehicle information acquisition device 2. The material of the second resin member 3 may be a material (for example, ceramic, glass, or the like) having a higher strength than the first resin member, but if the material is a member different from the first resin member, the effect of protecting the first resin member can be expected even if the material is the same as the first resin member. In addition, although the resin member may be degraded by solar irradiation, the second resin member 3 is positioned outside, so that degradation of the first resin member can be suppressed.
Example 2
The in-vehicle information acquiring apparatus housing according to embodiment 2 will be specifically described with reference to fig. 3. Fig. 3 is a cross-sectional view showing a schematic configuration of a housing of the in-vehicle information acquiring apparatus according to embodiment 2, and corresponds to fig. 2 of embodiment 1. In the present embodiment, a gap is formed between the cover main body 1 and the second resin member 3 at least in the field of view of the in-vehicle information acquiring device 2. This can suppress the first resin member from being scratched even when a mechanical impact is applied to the second resin member 3. In addition, as in the present embodiment, the existence of voids can also suppress visible light moire.
In addition, a transparent medium 6 different from the first resin member and the second resin member 3 is present in the space. When the medium 6 is air, the size of the gap, that is, the distance between the first resin member and the second resin member 3 is preferably a predetermined size that does not come into contact with the first resin member even when the second resin member 3 is elastically deformed to the limit. Here, if the medium 6 is air, dew condensation may occur on the inner surface of the second resin member 3. However, the second resin member 3 is fixed to only the upper and lower regions of the window portion 1a by the adhesive 5, and thus the dew condensation water generated can be discharged from the left and right of the window portion 1 a. In addition, since the distance between the first resin material and the second resin member 3 is ensured to have a predetermined size as described above, dew condensation water can be prevented from forming a film due to surface tension, and an influence on the information acquisition accuracy of the in-vehicle information acquisition device 2 can be suppressed.
On the other hand, in the case of using a gel or a liquid as the medium 6, dew condensation in the void can be prevented. In this case, it is necessary to seal the gap by fixing the second resin member 3 to the first resin member over the entire circumference. In the case of using a solid as the medium 6, for example, an elastomer having a smaller young's modulus than the first resin member and the second resin member 3 is preferable.
In the present embodiment, protruding portions protruding forward are formed on at least the upper and lower regions of the window portion 1a of the cover main body 1, and the rear surface of the second resin member 3 and the first resin member are fixed by the adhesive 5 applied on the front surface of the protruding portions. In this way, the presence of the protruding portion can ensure that the gap has a predetermined size. The same space may be formed by providing a concave portion instead of a convex portion in the field of view of the in-vehicle information acquisition device 2 (the information acquisition region 4 shown in fig. 3) on the front surface side of the cover main body 1. Further, by the structure in which the convex portion or the concave portion is provided not in the second resin member 3 but in the cover main body 1, the operability after the installation of the vehicle including the replacement operation of the second resin member 3 is improved.
Fig. 4 is a cross-sectional view showing a schematic configuration of a housing of the in-vehicle information acquisition device according to a modification of embodiment 2. In the present modification, convex portions protruding rearward are formed in the upper and lower regions of the second resin member 3, and the back surface of the convex portions and the first resin member of the cover main body 1 are fixed by the adhesive 5. Instead of providing the convex portions, the gaps may be formed by providing concave portions in the field of view of the in-vehicle information acquisition device 2 (the information acquisition region 4 shown in fig. 4) on the back surface side of the second resin member 3. According to this modification, since the second resin member 3, which is a smaller component than the cover main body 1, is processed, there is an advantage in that the entire in-vehicle information acquisition device cover can be easily manufactured. The above-described void may be formed by providing a convex portion or a concave portion in both the second resin member 3 and the cover body 1.
Example 3
The housing of the in-vehicle information acquiring apparatus according to embodiment 3 will be specifically described with reference to fig. 5 and 6. Fig. 5 is a front perspective view showing a schematic structure of a housing of the in-vehicle information acquiring apparatus according to embodiment 3, and fig. 6 is a sectional view B-B of fig. 5. In this embodiment, unlike in embodiment 1 and embodiment 2, the second resin member 3 is fixed to the cover body 1 by rivets 7. In the present embodiment, since the second resin member 3 is fixed to the first resin member only at one place above the visual field of the in-vehicle information acquisition device 2 (the information acquisition area 4 shown in fig. 6), not only is the fixation of the second resin member 3 easy, but also the replacement in the case where the second resin member 3 is damaged or the like is easy. In addition, by setting the position where the rivet 7 penetrates the first resin member so as not to face the in-vehicle information acquiring device 2, the waterproof performance of the in-vehicle information acquiring device 2 by the cover main body 1 can be maintained.
Fig. 7 is a cross-sectional view showing a schematic configuration of a housing of the in-vehicle information acquisition device according to a modification of embodiment 3. In the present modification, the second resin member 3 is fixed to the cover main body 1 using a screw 8 instead of the rivet 7. According to this modification, the second resin member 3 is more easily replaced when damaged or the like than in example 3.
Example 4
The housing of the in-vehicle information acquiring apparatus according to embodiment 4 will be specifically described with reference to fig. 8. Fig. 8 is a cross-sectional view showing a schematic configuration of a housing of the in-vehicle information acquiring apparatus according to embodiment 4, and corresponds to fig. 2 of embodiment 1. In the present embodiment, the second resin member 3 is directly fixed to the vehicle support 9, which is a structural body of the straddle-type vehicle, by the rivet 7. According to the present embodiment, since the hole through which the rivet 7 penetrates is not formed on the first resin member, the waterproof property of the cover main body 1 can be maintained, and the manufacturability of the in-vehicle information acquiring device housing is also improved.
The present invention is not limited to the above embodiments, and various modifications can be made. The above-described embodiments are exemplified for easier understanding and explanation of the present invention, and are not necessarily limited to the entire structure having been explained. In addition, a part of the structure of one embodiment may be replaced with the structure of another embodiment, and the structure of another embodiment may be added to the structure of one embodiment. In addition, other structures may be added, deleted, or replaced for a part of the structures of the embodiments.
