Description

Technical Field

[0001] The present invention relates to a radar device. Background Art

[0002] In the past, there are known radar devices that use radar to identify objects such as other vehicles that exist around the vehicle, such as other vehicles that are diagonally in front of the vehicle's traveling direction. In these radar devices, for example, a technology for improving the durability of the radar device by protecting the radar from various external factors has been proposed.

[0003] For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2007-106199) discloses a radar device structure in which a radar is arranged inside a resin bumper provided on a vehicle. A radar main body is attached to the bumper via a radar bracket inside the bumper.

[0004] According to the technology described in Patent Document 1, microwaves excited from the radar body are emitted through the bumper as a resin member, and reflected waves are received by the bumper. By arranging the radar inside the bumper, dirt is less likely to adhere to the radar body. This can improve the durability of the radar device. Summary of the invention

[0005] [Summary of the Invention]

[0006] [Problems to be solved by the invention]

[0007] However, in the technology described in Patent Document 1, the bumper is connected to the radar body via the bumper bracket. Therefore, when an impact is input to the bumper from the outside, the impact is easily transmitted to the radar body via the bumper bracket. As a result, the radar body cannot be fully protected, and the installation position of the radar may be displaced due to the impact. Therefore, in the prior art, there is room for improvement in improving the durability of the radar device against various external factors.

[0008] Therefore, an object of the present invention is to provide a radar device capable of improving durability against external factors compared with the conventional technology.

[0009]

Solutions to Solve the Problem

[0010] In order to solve the above-mentioned problems, a radar device according to the present invention has the following configuration.

[0011] (1) A radar device according to one aspect of the present invention comprises: a lamp body provided on a vehicle body; a bumper provided on an outer surface of the vehicle body; a bumper beam provided at a position closer to the vehicle body than the bumper and receiving a load input to the bumper from the outside; a vehicle frame to which the bumper beam is mounted; a corner upper beam provided at a position closer to the vehicle body than the bumper and provided between the lamp body and the bumper beam in a vertical direction; and a radar main body mounted on the corner upper beam.

[0012] (2) In the radar device according to the above-mentioned aspect (1), the corner upper member may have a recessed portion recessed toward the inner side of the vehicle body, and the radar main body may be mounted inside the recessed portion.

[0013] (3) In the radar device of the above-mentioned scheme (2), the recess may have an inner wall along the up-down direction, an upper wall extending from the upper end of the inner wall toward the outer side of the vehicle body, and a lower wall extending from the lower end of the inner wall toward the outer side of the vehicle body, and the radar body may be installed on the inner wall.

[0014] (4) In the radar device of the above-mentioned scheme (1), the bumper beam may also have an elastic member, which is formed into a plate shape by metal and resin materials and is bent by receiving the load input from the bumper, and the radar body may also be arranged at a position that does not overlap with the elastic member in the up-down direction.

[0015] (5) In the radar device according to the above-mentioned aspect (1), the corner upper beam may be mounted on the vehicle frame via a connecting member and connected to the lamp body to hold the lamp body on the vehicle body.

[0016] [Effects of the invention]

[0017] According to the scheme of (1), the radar device includes a lamp body, a bumper, a bumper beam, a corner upper beam and a radar body. The corner upper beam is arranged at a position on the inner side of the vehicle body than the bumper, and is arranged between the lamp body and the bumper beam in the up and down direction. The radar body is installed on the corner upper beam. Since the radar body is arranged on the inner side of the bumper, the radar body can be protected from water droplets, dirt splashed from the road surface, pebbles, etc. As a result, the degradation of radar performance caused by raindrops, dirt, etc. adhering to the radar body can be suppressed, and the durability of the radar device can be improved.

[0018] On the other hand, the bumper is a component provided on the outer surface of the vehicle body, and is the first component to be input with a load when, for example, an object contacts the vehicle from the outside. Similarly, the bumper beam bears the load input to the bumper from the outside. Therefore, the bumper and the bumper beam are prone to vibration, deformation, misalignment, etc. due to the load from the outside. According to the structure of the present invention, the radar body is mounted on a corner upper beam that is separate from the bumper and the bumper beam. Therefore, even when loads and vibrations are input to the bumper and the bumper beam from the outside, the transmission of these loads to the radar body can be suppressed. As a result, compared with the prior art in which, for example, the radar body is connected to the bumper via a bracket, the influence of the external load on the radar body can be reduced.

[0019] Therefore, it is possible to provide a radar device capable of improving durability against external factors compared with the conventional technology.

[0020] Furthermore, the radar body is mounted on a corner upper beam that is separate from the bumper, so that the radar body can be easily replaced compared to the prior art in which the radar body is directly or indirectly mounted on the bumper. Since the radar body is provided on the corner upper beam for positioning the lamp body, the structure can be simplified compared to a case where a bracket or the like for mounting the radar body is separately provided. Thus, the weight and number of components of the radar device can be reduced. Furthermore, the radar body is mounted on a member (i.e., the corner upper beam) that is different from the lamp body and the bumper beam, so that, for example, the radar body can be mounted on the vehicle body without affecting the design of the lamp body. Thus, it can be a structure that is particularly suitable when it is not preferred to install the radar body in the lamp body due to space problems or design problems.

[0021] According to the solution of (2), the corner upper beam has a recessed portion, and the radar body is installed inside the recessed portion. As a result, even if water drops, dirt, etc. enter from the gap between the bumper and the frame, the water drops and dirt are unlikely to adhere to the radar body. As a result, the radar body can be protected from the influence of external dirt, etc., and the performance degradation of the radar body such as the decrease in detection accuracy and the decrease in durability caused by the adhesion of dirt, etc. can be suppressed.

[0022] According to the scheme of (3), the recessed portion of the corner upper beam has at least an inner wall on which the radar body is mounted, and an upper wall and a lower wall. By providing the upper wall, it is possible to use the upper wall to block water drops that, for example, enter from above the radar body due to rain. By providing the lower wall, it is possible to use the lower wall to block dirt, water drops, pebbles, etc. that are splashed from the road surface. Thus, the recessed portion is formed by at least the inner wall, the upper wall, and the lower wall, so that the radar body can be effectively protected from dirt, etc. from the outside. Therefore, the durability of the radar device can be improved with a simple structure.

[0023] According to the scheme of (4), the bumper beam has an elastic member formed into a plate shape by a material made of metal and resin. The elastic member is configured to bend in response to a load input from the bumper, so that the load input from the bumper can be absorbed by the elastic member. The radar body is arranged at a position that does not overlap with the elastic member in the up and down directions. Thus, it is possible to suppress the interference between the radio waves excited from the radar body and the metal elastic member. Thus, not only the influence on the load can be reduced, but also the electromagnetic influence on the radar body can be reduced, and the detection accuracy of the radar device can be maintained high.

[0024] According to the scheme of (5), the corner upper beam is mounted on the vehicle frame via a connecting member. As a result, the corner upper beam can be configured separately from the bumper and the bumper beam. As a result, the load transmitted to the bumper and the bumper beam is difficult to be transmitted to the corner upper beam. In other words, the influence from the outside on the radar body mounted on the corner upper beam can be reduced.

[0025] The corner upper beam is connected to the lamp body to hold the lamp body on the vehicle body. As a result, the component for holding the lamp body and the component for installing the radar body can be made into a common component. As a result, the number of components can be reduced compared to the case where different components are used to hold the lamp body and install the radar body. In particular, the corner upper beam is a component pre-set to hold the lamp body. Therefore, by using the corner upper beam as the installation of the radar body, the radar body can be mounted on the vehicle body without significantly changing the existing layout.

[0047] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, the front-rear, left-right, and up-down directions are consistent with the front-rear, left-right, and up-down directions of the vehicle body 10 unless otherwise specified. The left-right direction is sometimes referred to as the vehicle width direction. The arrow FR in the figure points to the front of the vehicle, the arrow UP points to the top of the vehicle, and the arrow LH points to the left of the vehicle.

[0048] (Radar device)

[0049] Figure 1 It is a front view of a vehicle body 10 on which the radar device 1 according to the embodiment is mounted. Figure 2 It is omitted Figure 1 FIG. 1 is a front view of a vehicle body 10 showing the bumper 3 in FIG.

[0050] like Figure 1 and Figure 2 As shown in the figure, the radar device 1 of the present embodiment is respectively installed on the left and right sides of the front of the vehicle body 10. The radar device 1 is, for example, a device for detecting other vehicles not shown in the figure that exist obliquely in front of the vehicle body 10 while the vehicle body 10 is traveling. It should be noted that in the following description, the radar device 1 installed on the left front part of the vehicle body 10 is described, and the description of the radar device 1 installed on the right front part of the vehicle body 10 is omitted.

[0051] Figure 3 FIG. 1 is a side view of a vehicle body 10 on which the radar device 1 according to the embodiment is mounted. Figure 3 In the figure, the bumper 3 is omitted for the sake of explanation. Figure 4It is a schematic explanatory diagram of the radar device 1 according to the embodiment. Figure 4 This is a schematic explanatory diagram of the radar device 1 when the vehicle body 10 is viewed from the left side.

[0052] like Figure 2 to Figure 4 As shown, the radar device 1 includes a lamp body 2 , a bumper 3 , a bumper beam 4 , a vehicle frame 5 , a corner upper beam 6 , and a radar main body 7 .

[0053] (Lamp body)

[0054] The lamp body 2 is, for example, a headlight. The lamp body 2 is disposed at positions corresponding to the left and right corners of the front of the vehicle body 10. The upper end of the lamp body 2 is connected to the front engine hood. The lamp body 2 is connected to the vehicle frame 5 on the inner side of the vehicle body 10 (see FIG. Figure 4 ).like Figure 1 As shown, the lamp body 2 has a plurality of LEDs 11 inside (see Figure 1 ) A plurality of LEDs 11 are arranged in a row along the vehicle width direction.

[0055] It should be noted that the arrangement position of the LED 11 in the lamp body 2 is not limited to Figure 1 The part shown in the figure.

[0056] (bumper)

[0057] like Figure 1 and Figure 4 As shown in FIG. 1 , the bumper 3 is provided on the outer surface of the vehicle body 10. The bumper 3 forms the outermost surface of the vehicle body 10 in a manner covering the portion below the lamp body 2. The bumper 3 is formed of a material such as resin. The lower end of the bumper 3 is connected to the vehicle body 10 via a bumper bracket not shown. The bumper 3 bulges forward when viewed from the side (see FIG. 1 ). Figure 4 ).

[0058] (Bumper beam)

[0059] like Figure 2 to Figure 4 As shown in FIG. 1 , the bumper beam 4 is disposed at a position inside the vehicle body 10 relative to the bumper 3. The bumper beam 4 is disposed at the same position as the bumper 3 in the vertical direction. In other words, the bumper beam 4 is covered by the bumper 3 from the outside of the vehicle body 10. Figure 4 As shown, the bumper beam 4 receives the load F inputted from the outside to the bumper 3. Specifically, before the load F is inputted to the vehicle body 10, the bumper 3 and the bumper beam 4 are arranged to be separated from each other in the front-rear direction. When the load F is inputted from the front of the vehicle body 10 to the bumper 3, the bumper 3 is deformed and displaced rearward, whereby the bumper 3 abuts against the bumper beam 4. The bumper 3 abuts against the bumper beam 4, so that the bumper beam 4 can receive the load F inputted from the bumper 3 and absorb the load F.

[0060] like Figure 2 and Figure 3 As shown, the bumper beam 4 has a bumper beam body 16 and an elastic member 18 .

[0061] The bumper beam body 16 extends in the vehicle width direction. The bumper beam body 16 has a front surface facing forward, a rear surface facing rearward, an upper surface connecting the upper ends of the front surface and the rear surface, and a lower surface connecting the lower ends of the front surface and the rear surface. The bumper beam body 16 is formed into a tubular shape having a closed cross section when viewed from the side by the front surface, the rear surface, the upper surface, and the lower surface. The bumper beam body 16 is bent in a manner convex to the front when viewed from the top and bottom directions. The rear end of the bumper beam body 16 is fixed to the vehicle frame 5 by a fastening member (not shown) such as bolts.

[0062] The elastic member 18 is arranged at a position forward of the bumper beam body 16. The elastic member 18 is arranged at a position overlapping with the central portion of the bumper beam body 16 in the up-down direction. The elastic member 18 extends in the vehicle width direction. The elastic member 18 is formed of a metal and resin material. The elastic member 18 is formed in a plate shape with the inner and outer directions of the vehicle body 10 as the thickness direction. The elastic member 18 is a leaf spring that is bent by the load F input from the bumper 3. The elastic members 18 are respectively arranged at positions corresponding to the left front and right front corners of the vehicle body 10. The elastic members 18 are mutually symmetrical in shape, so the elastic member 18 on the left is described below.

[0063] The elastic member 18 is curved so as to protrude outward in the vehicle width direction when viewed from the top and bottom, similarly to the bumper beam body 16. The outer end of the elastic member 18 in the vehicle width direction is fixed to the vehicle frame 5 by a fastening member 32 such as a bolt.

[0064] (Frame)

[0065] The vehicle frame 5 constitutes a skeleton portion of the vehicle body 10. The above-mentioned bumper beam 4 is mounted on the vehicle frame 5. Furthermore, the fender 26 for fixing a corner upper beam 6 described in detail later is mounted on the vehicle frame 5.

[0066] (Corner upper beam)

[0067] The corner upper beam 6 is provided at a position closer to the inside of the vehicle body 10 than the bumper 3. The corner upper beam 6 is formed of a material such as resin. The corner upper beam 6 is provided between the lamp body 2 and the bumper beam 4 in the vertical direction. The corner upper beam 6 is provided at positions corresponding to the left front and right front corners of the vehicle body 10, respectively. A pair of corner upper beams 6 are mutually symmetrical in shape, so the left corner upper beam 6 will be described below.

[0068] The corner upper beam 6 extends in the vehicle width direction along the lower end of the lamp body 2. Like the lamp body 2, the corner upper beam 6 is gently curved so as to protrude toward the outside of the vehicle body 10 when viewed from the top and bottom. The corner upper beam 6 is formed so that the width dimension in the top and bottom direction increases from the inside to the outside in the vehicle width direction when viewed from the front. More specifically, the height of the lower end of the corner upper beam 6 is almost the same height in the top and bottom direction without changing from the inside to the outside in the vehicle width direction. On the other hand, the position of the upper end of the corner upper beam 6 gradually changes so as to be located at an upper position from the inside to the outside in the vehicle width direction.

[0069] The outer end of the corner upper beam 6 in the vehicle width direction is attached to the vehicle frame 5 (see also) via the fender 26 (connecting member of the technical solution). Figure 4 ). Moreover, the upper end of the corner upper beam 6 is connected to the lamp body 2. Thus, the corner upper beam 6 holds the lamp body 2 on the vehicle body 10. It is preferred that the mounting point (fastening connection point based on bolts, etc.) of the corner upper beam 6 to which the lamp body 2, fender 26, etc. are mounted is set at a position that does not interfere with the mounting point of the radar body 7 to be described later to the corner upper beam 6. In the case of such a configuration, for example, the corner upper beam 6 can be mounted to the vehicle body 10 in a state where the radar body 7 is first mounted on the corner upper beam 6. That is, it can be made into an assembly, and the workability during manufacturing can be improved.

[0070] Figure 5 It is a perspective view of the lamp body 2, the corner upper beam 6 and the radar body 7 according to the embodiment.

[0071] like Figure 5 As shown, the corner upper member 6 has a recessed portion 20 recessed from the outside (vehicle exterior side) toward the inside (interior side) of the vehicle body 10. The recessed portion 20 is formed integrally with the corner upper member 6 by, for example, injection molding a resin material.

[0072] In the present embodiment, the recessed portion 20 of the corner upper beam 6 includes an inner wall 21 , an upper wall 22 , a lower wall 23 , a first side wall 24 , and a second side wall 25 .

[0073] The inner wall 21 constitutes the bottom of the recessed portion 20 and is provided along the vertical direction and the vehicle width direction. The inner wall 21 is formed in a plate shape with the inner and outer directions of the vehicle body 10 as the thickness direction.

[0074] The upper wall 22 extends from the upper end of the inner wall 21 toward the outside of the vehicle body 10. The upper wall 22 is provided on the entire upper end of the corner upper member 6.

[0075] The lower wall 23 extends from the lower end of the inner wall 21 toward the outer side of the vehicle body 10. The lower wall 23 is provided on the entire lower end of the corner upper member 6.

[0076] The first side wall 24 connects the outer end of the upper wall 22 in the vehicle width direction to the outer end of the lower wall 23 in the vehicle width direction. The first side wall 24 extends in the up-down direction. The inner end of the vehicle body 10 of the first side wall 24 is connected to the inner wall 21. The first side wall 24 is provided along the outer end of the corner upper beam 6 in the vehicle width direction.

[0077] The second side wall 25 connects the center of the upper wall 22 in the vehicle width direction to the center of the lower wall 23 in the vehicle width direction. The second side wall 25 extends in the up-down direction. The end of the second side wall 25 on the inner side of the vehicle body 10 is connected to the inner wall 21.

[0078] The inner wall 21 , the upper wall 22 , the lower wall 23 , the first side wall 24 , and the second side wall 25 form a recessed portion 20 that opens to the outside of the vehicle body 10 .

[0079] In this embodiment, a plurality of ribs 30 extending in the vertical direction are provided in the region of the corner upper member 6 that is on the inner side of the second side wall 25 in the vehicle width direction. Each rib 30 is connected to the upper wall 22, the lower wall 23, and the inner wall 21. Each rib 30 reinforces the corner upper member 6.

[0080] (Radar body)

[0081] like Figure 2 to Figure 5 As shown in FIG. 1 , the radar body 7 is respectively installed on the left and right corner upper beams 6. The left and right radar bodies 7 have the same structure, so the left radar body 7 is described below. The radar body 7 is formed as a rectangular plate. The radar body 7 is a millimeter wave radar with a detection range set outside the left oblique front of the vehicle. Figure 2 and Figure 3 As shown, one main surface of the radar body 7 faces the oblique left front of the vehicle and can transmit millimeter wave radio waves. The radar body 7 transmits radar radio waves as electromagnetic waves to the detection range, and receives reflected waves generated by the reflection of each transmitted wave by an object outside the vehicle (such as another vehicle, an obstacle, etc.). Based on the transmitted wave and the reflected wave, the radar body 7 outputs a detection signal related to, for example, the distance from the radar body 7 to the external object, the relative speed of the external object based on the Doppler effect, the relative position and orientation of the external object relative to the radar body 7, etc.

[0082] like Figure 5As shown in FIG. 1 , the radar body 7 is mounted inside the recess 20 in the corner upper beam 6. Specifically, the back side of the radar body 7 opposite to one main surface is mounted on the inner wall 21 of the corner upper beam 6 where the recess 20 is formed. The radar body 7 is fixed to the inner wall 21 by a fastening member (not shown) such as a bolt. A hole 35 is formed in the portion of the inner wall 21 of the corner upper beam 6 where the radar body 7 is mounted, which penetrates the inner wall 21 in the thickness direction. The wiring of the radar body 7 is arranged on the back side of the corner upper beam 6 through the hole 35.

[0083] Figure 6 FIG. 1 is a top view of the vehicle body 10 according to the embodiment. Figure 6 As shown in FIG. 1 , when viewed from above, the radar main body 7 is arranged in a radar configurable area 50, which is a place where the radar main body 7 can be arranged. The radar configurable area 50 is located between the lamp body 2 and the bumper 3 in the front-rear direction. The radar configurable area 50 is located at a position closer to the inner side of the vehicle body 10 than the outermost surface of the bumper 3. As a result, the radar main body 7 is less susceptible to external influences. The irradiation area (not shown) of the radar wave from the radar main body 7 is set so as not to be the outermost end of the bumper 3.

[0084] like Figure 2 and Figure 3 As shown, the radar body 7 is arranged at a position lower than the lamp body 2 and higher than the bumper beam 4 in the vertical direction. In particular, the radar body 7 is arranged at a position that does not overlap with the elastic member 18 of the bumper beam 4 in the vertical direction. In this way, by arranging the metal elastic member 18 separately from the radar body 7, the electromagnetic influence on the radar wave when the radar wave is excited forward from the radar body 7 can be suppressed.

[0085] (Function, Effect)

[0086] Next, the operation and effects of the above-mentioned radar device 1 will be described.

[0087] According to the radar device 1 of the present embodiment, the radar device 1 includes a lamp body 2, a bumper 3, a bumper beam 4, a corner upper beam 6, and a radar body 7. The corner upper beam 6 is provided at a position closer to the inside of the vehicle body 10 than the bumper 3, and is provided between the lamp body 2 and the bumper beam 4 in the up-down direction. The radar body 7 is mounted on the corner upper beam 6. Since the radar body 7 is provided on the inside of the bumper 3, the radar body 7 can be protected from water droplets, dirt splashed from the road surface, pebbles, and the like. Thus, it is possible to suppress the degradation of radar performance caused by the attachment of raindrops, dirt, and the like to the radar body 7, and improve the durability of the radar device 1.

[0088] On the other hand, the bumper 3 is a component provided on the outer surface of the vehicle body 10, and is a component to which the load F is first input when, for example, an object abuts against the vehicle from the outside. Similarly, the bumper beam 4 bears the load F input to the bumper 3 from the outside. Therefore, the bumper 3 and the bumper beam 4 are susceptible to vibration, deformation, misalignment, etc. due to the load F from the outside. According to the structure of the present invention, the radar body 7 is mounted on the corner upper beam 6 that is separate from the bumper 3 and the bumper beam 4. Therefore, even when the load F and vibration are input to the bumper 3 and the bumper beam 4 from the outside, the transmission of these loads F to the radar body 7 can be suppressed. As a result, compared with the prior art in which, for example, the radar body 7 is connected to the bumper 3 via a bracket, the influence of the load F from the outside on the radar body 7 can be reduced.

[0089] Therefore, it is possible to provide a radar device 1 that can improve durability against external factors compared to the conventional technology.

[0090] Furthermore, since the radar body 7 is mounted on the corner upper beam 6 which is separate from the bumper 3, it is easier to replace the radar body 7 than in the prior art in which the radar body 7 is directly or indirectly mounted on the bumper 3. Since the radar body 7 is provided on the corner upper beam 6 for positioning the lamp body 2, the structure can be simplified compared to the case where a bracket or the like for mounting the radar body 7 is separately provided. Thus, the weight and number of components of the radar device 1 can be reduced. Furthermore, since the radar body 7 is mounted on a member (i.e., the corner upper beam 6) which is different from the lamp body 2 and the bumper beam 4, for example, the radar body 7 can be mounted on the vehicle body 10 without affecting the design of the lamp body 2. Thus, it can be a particularly suitable structure in the case where it is not preferred to install the radar body 7 in the lamp body 2 due to space problems or design problems.

[0091] The corner upper beam 6 has a recessed portion 20, and the radar body 7 is mounted inside the recessed portion 20. Thus, even if water drops, dirt, etc. enter from the gap between the bumper 3 and the frame 5, the water drops and dirt are unlikely to adhere to the radar body 7. Thus, the radar body 7 can be protected from the influence of external dirt, etc., and the performance degradation of the radar body 7 such as the degradation of detection accuracy and the degradation of durability caused by the adhesion of dirt, etc. can be suppressed.

[0092] The recessed portion 20 of the corner upper beam 6 has at least an inner wall 21 on which the radar body 7 is mounted, and an upper wall 22 and a lower wall 23. By providing the upper wall 22, water drops that enter from above the radar body 7 due to, for example, rain, etc. can be blocked by the upper wall 22. By providing the lower wall 23, dirt, water drops, pebbles, etc. that are splashed from the road surface, for example, can be blocked by the lower wall 23. Thus, the recessed portion 20 is formed by at least the inner wall 21, the upper wall 22, and the lower wall 23, so that the radar body 7 can be effectively protected from dirt, etc. from the outside. Therefore, the durability of the radar device 1 can be improved with a simple structure.

[0093] The bumper beam 4 has an elastic member 18 formed into a plate shape by a material made of metal and resin. The elastic member 18 is configured to bend in response to the load F input from the bumper 3, so the load F input from the bumper 3 can be absorbed by the elastic member 18. The radar body 7 is arranged at a position that does not overlap with the elastic member 18 in the up and down direction. As a result, it is possible to suppress the interference of the radio waves excited from the radar body 7 with the metal elastic member 18. As a result, not only the influence on the load F can be reduced, but also the electromagnetic influence on the radar body 7 can be reduced, and the detection accuracy of the radar device 1 can be maintained high.

[0094] The corner upper beam 6 is mounted on the vehicle frame 5 via the fender 26 (connecting member of the technical solution). As a result, the corner upper beam 6 can be arranged separately from the bumper 3 and the bumper beam 4. As a result, the load F transmitted to the bumper 3 and the bumper beam 4 is difficult to be transmitted to the corner upper beam 6. That is, the influence from the outside on the radar body 7 mounted on the corner upper beam 6 can be reduced.

[0095] The corner upper beam 6 is connected to the lamp body 2 to hold the lamp body 2 on the vehicle body 10. Thus, the component for holding the lamp body 2 and the component for mounting the radar body 7 can be made into a common component. Thus, the number of components can be reduced compared to the case where the lamp body 2 is held and the radar body 7 is mounted by different components. In particular, the corner upper beam 6 is a component that is pre-set to hold the lamp body 2. Therefore, by using the corner upper beam 6 as a mounting component for the radar body 7, the radar body 7 can be mounted on the vehicle body 10 without significantly changing the existing layout.

[0096] It should be noted that the technical scope of the present invention is not limited to the above-mentioned embodiment, and various modifications can be made without departing from the gist of the present invention.

[0097] For example, in the above-mentioned embodiment, the radar device 1 is provided in front of the vehicle body 10, but the present invention is not limited thereto. A pair of left and right radar devices 1 may be provided behind the vehicle body 10. In this case, the radar device 1 may be configured to detect an object behind the vehicle.

[0098] It is sufficient to provide at least the inner wall 21, the upper wall 22 and the lower wall 23 on the corner upper beam 6, and it is not necessary to provide the first side wall 24 and the second side wall 25. However, the structure of this embodiment having the first side wall 24 and the second side wall 25 is superior in that it can further suppress the intrusion of water drops, dirt, etc.

[0099] The shape, number, etc. of the ribs 30 of the corner upper beam 6 are not limited to the above-mentioned configuration. The ribs 30 may not be provided.

[0100] Furthermore, components in the above-described embodiments may be appropriately replaced with well-known components without departing from the gist of the present invention, and the above-described embodiments may be appropriately combined.
