Detailed Description
Hereinafter, one embodiment of the lamp body device of the present invention will be described with reference to the drawings.
[ embodiment ]
Hereinafter, a vehicle as one embodiment to which the lamp body device of the present invention is applied will be described with reference to the drawings. The drawings are viewed from the direction of the symbols. In the present specification and the like, for the sake of simplicity and clarity of description, the front-rear direction, the left-right direction, the rear-left direction, the left-right direction, the upper-upper direction, and the lower-lower direction are described as viewed from the driver of the vehicle, and in the drawings, the front of the vehicle is represented by Fr, the rear is represented by Rr, the left is represented by L, the right is represented by R, and the lower is represented by D.
First, a structure of a vehicle 10 according to an embodiment will be described with reference to fig. 1. The vehicle 10 is a mobile body capable of autonomous movement.
The vehicle 10 is an automobile having a drive source (not shown) and wheels including drive wheels driven by power of the drive source and steerable wheels. In the present embodiment, the vehicle 10 is a four-wheeled automobile having a pair of left and right front wheels and rear wheels. The drive source of the vehicle 10 is, for example, an electric motor. The drive source of the vehicle 10 may be an internal combustion engine such as a gasoline engine or a diesel engine, or may be a combination of an electric motor and an internal combustion engine. The drive source of the vehicle 10 may drive a pair of left and right front wheels, a pair of left and right rear wheels, or four wheels of the pair of left and right front wheels and rear wheels. The front wheels and the rear wheels may be steerable wheels, both of which are steerable, or may be steerable wheels, either of which is steerable.
The vehicle 10 includes: a frame member (not shown) having a monocoque structure assembled by welding of steel plate panels, for example; and a housing member 1 that covers the skeleton member to constitute a housing of the vehicle 10. A vehicle interior for accommodating occupants and a front compartment formed in front of the vehicle interior are provided in a space surrounded by the shell member. A drive source of the vehicle 10 and the like are housed in the front compartment.
A lamp body device 11 is provided on the left side of the front surface of the vehicle 10, and a lamp body device (not shown) is also provided on the right side of the front surface of the vehicle 10. The lamp body devices of the present invention can be applied to, for example, the left and right lamp body devices.
Next, the structure of the lamp body device 11 will be described with reference to fig. 2 and 3. The lamp body device 11 has a lamp chamber 12 surrounded by a housing 12a and a transparent cover 12 b. The lamp chamber 12 is provided with a first lamp body 21, a second lamp body 22, and a radar transceiver 23. The transparent cover 12b is a transparent cover that transmits visible light from the first lamp body 21 and the second lamp body 22 or radio waves from the radar transceiver 23, and forms a part of the outer surface of the vehicle 10.
The first lamp body 21 is a headlamp that emits illumination light toward a region including the front of the vehicle 10 in order to illuminate the front of the vehicle 10. The second lamp body 22 is a turn signal lamp that emits a signal light toward a region including the front of the vehicle 10 to display a direction around the vehicle 10 when the vehicle 10 turns left or right or a road changes. The first lamp body 21 and the second lamp body 22 can each be realized by, for example, an LED (Light Emitting Diode).
The radar transceiver 23 is provided toward the outside (in this example, the front) of the vehicle 10. That is, the radar transceiver 23 radiates radio waves to the outside (front) of the vehicle 10 and receives radio waves reflected by an object outside the vehicle 10, thereby detecting the position (distance from the vehicle 10, direction) of the object outside the vehicle 10. The radio wave radiated from the radar transceiver 23 is, for example, a millimeter wave having a frequency of about 70 to 90[ GHz ].
The radar transceiver 23 is provided adjacent to at least one of the first lamp body 21 and the second lamp body 22. In this example, the radar transceiver 23 is disposed between the first and second lamp bodies 21 and 22 adjacent to the first and second lamp bodies 21 and 22. The detection result of the radar transceiver 23 is output to a Control device such as an ECU (Electronic Control Unit) provided in the vehicle 10, and is used for automatic driving and driving assistance of the vehicle 10.
Next, the structure of the radar transceiver 23 will be described with reference to fig. 4. The radar transceiver 23 has an antenna cover 23a that protects an antenna for transmitting and receiving radio waves. An indium layer 23b is formed on a surface of the antenna cover 23a that can be viewed from the outside (in this example, the front) of the vehicle 10. The indium layer formed so as to cover the surface of the antenna cover 23a in the radar transceiver 23 is, for example, a film body formed by vapor-depositing indium on the surface of the antenna cover 23a of the radar transceiver 23.
Since indium has metallic luster, it does not give a sense of incongruity even if it is disposed adjacent to the first lamp body 21 and the second lamp body 22 in the lamp chamber 12, and does not impair the aesthetic appearance of the lamp body device 11. Further, since the light emitted from the first lamp body 21 and the second lamp body 22 is also reflected by the indium layer 23b, the lamp body device 11 can be provided with an impressive appearance.
Further, since indium has radio wave permeability for transmitting radio waves (millimeter waves) of the radar transceiver 23, even if the indium layer 23b is provided on the antenna cover 23a, it is possible to suppress a decrease in measurement accuracy of the radar transceiver 23.
Therefore, the lamp body device 11 including the radar transceiver 23 can be improved in appearance, and the decrease in the measurement accuracy of the radar transceiver 23 can be suppressed.
Next, a modification of the radar transceiver 23 will be described with reference to fig. 5. A frame 23c of a different color (blue as an example) from the indium layer 23b may be provided on the outer peripheral portion of the indium layer 23b on the surface of the antenna cover 23a that can be viewed from the outside (front in this example) of the vehicle 10.
The frame 23c may be formed by applying paint of a color different from that of the indium layer 23b to the outer peripheral portion of the indium layer 23b in the surface of the antenna cover 23a, or may be formed by providing a frame body of a color different from that of the indium layer 23b in the antenna cover 23 a.
By providing the frame 23c having a color different from that of the indium layer 23b on the outer peripheral portion of the indium layer 23b having a metallic luster, the appearance of the lamp body device 11 can be further improved. The frame 23c is provided so as to open a region through which the radio wave of the radar transceiver 23 passes, so as not to obstruct the transmission and reception of the radio wave (millimeter wave) by the radar transceiver 23.
Therefore, the appearance of the lamp body device 11 including the radar transceiver 23 can be further improved, and the decrease in the measurement accuracy of the radar transceiver 23 can be suppressed.
The lamp body device 11 provided on the left side of the front surface of the vehicle 10 has been described, but the lamp body device provided on the right side of the front surface of the vehicle 10 may be configured similarly to the lamp body device 11. Although not shown, the lamp body devices, not shown, disposed on the left and right behind the vehicle 10 may have the same configuration as the lamp body device 11.
Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and modifications, improvements, and the like can be appropriately made.
For example, as the lamp body provided in the lamp chamber 12, a structure may be adopted in which either the first lamp body 21 or the second lamp body 22 is omitted. In addition, the positions of the first lamp body 21, the second lamp body 22, and the radar transceiver 23 may be changed.
Further, although the structure in which the lamp bodies such as the first lamp body 21 and the second lamp body 22 and the radar transceiver 23 are disposed adjacent to each other in the horizontal direction has been described, the lamp bodies and the radar transceiver 23 may be disposed adjacent to each other in the vertical direction or the oblique direction.
The vehicle 10, which is a four-wheeled vehicle having a pair of left and right front wheels and rear wheels, has been described, but the lamp body device of the present invention may be provided in a motorcycle having one front wheel and one rear wheel. For example, in a motorcycle having a single lamp body and a lamp chamber in the center of the front surface, the radar transceiver 23 having the indium layer 23b may be provided in the lamp chamber. In this case, the lamp body and the radar transceiver 23 are preferably arranged adjacent to each other in the vertical direction.
