Description

The present invention relates to an adapter that holds a radar device, a radar unit that includes the adapter, and a vehicle that includes the radar unit.

Conventionally, some vehicles such as automobiles are equipped with a radar device using a laser radar, a millimeter wave radar, or the like in order to detect an obstacle. The radar device is used, for example, in an ACC system (adaptive cruise control system), a Stop & Go system (traffic jam tracking system), an inter-vehicle warning system, and the like.

As shown in Patent Document 1 and the like, such a radar device is held by an adapter and attached to a vehicle mounting portion. In Patent Document 1, the adapter is referred to as a support member. Further, although the adapter of Patent Document 1 is made of metal, in recent years, a resin adapter has also been proposed in consideration of the mountability of the radar device to the adapter.

A conventional resin adapter will be described. When the surface of the radar device facing the transmission / reception surface is the back surface, the conventional resin adapter includes a base portion facing the back surface of the radar device. Further, the conventional resin adapter includes a support portion that supports the lower surface of the radar device, and a tongue piece that presses the upper surface of the radar device toward the support portion. The tongue piece of the conventional resin adapter has a base directly connected to the base portion and extends toward the transmission / reception surface of the radar device so as to face the upper surface of the radar device. Further, when the adapter does not hold the radar device, the distance between the tongue piece and the support portion is smaller than the vertical width of the radar device.

When the conventional resin adapter holds the radar device, the back surface of the radar device is brought closer to the base portion of the adapter, and the radar device is inserted between the tongue piece and the support portion. As a result, the tongue piece is pushed upward at the portion in contact with the upper surface of the radar device. In other words, the portion of the tongue that is in contact with the upper surface of the radar device is pushed away from the support. Then, the tongue piece is elastically deformed with the base portion connected to the base portion as a fixed end. In other words, the tongue piece is elastically deformed between the portion in contact with the upper surface of the radar device and the base. The reaction force generated on the tongue piece when elastically deformed in this way becomes a force that pushes the upper surface of the radar device downward. That is, the reaction force of the tongue piece pushes the radar device toward the support portion. As a result, the conventional resin adapter holds the radar device by sandwiching the radar device in the vertical direction between the support portion and the tongue piece.

Japanese Unexamined Patent Publication No. 2017-215186

As described above, in the conventional resin adapter, the radar device is held by the reaction force generated by the elastic deformation between the portion of the tongue piece in contact with the upper surface of the radar device and the base portion. That is, in the conventional resin adapter, when the radar device is held by the adapter, the load pushed by the radar device is between the portion of the tongue piece in contact with the upper surface of the radar device and the base. Will be received at. At this time, the distance between the portion of the tongue piece in contact with the upper surface of the radar device and the base is short. Therefore, in the conventional resin adapter, when the radar device is held by the adapter, stress concentration tends to occur at the base portion where the tongue piece is fixed. Therefore, the conventional resin adapter has a problem that when a time elapses while holding the radar device, a creep phenomenon occurs at the base of the tongue piece and the holding force of the radar device is lowered.

The present invention has been made against the background of the above-mentioned problems, and is a resin adapter used when mounting a radar device on a vehicle, and suppresses a decrease in holding power of the radar device as compared with the conventional case. The primary purpose is to provide an adapter capable of this. A second object of the present invention is to provide a radar unit provided with such an adapter. A third object of the present invention is to provide a vehicle provided with such a radar unit.

The adapter according to the present invention is a resin adapter that is attached to a mounting portion of a vehicle and holds a radar device. The surface facing the transmission / reception surface of the radar device is the back surface, and the transmission / reception surface and the back surface are the back surface. When one of the side surfaces of the radar device to be connected is the first side surface and the side surface of the radar device facing the first side surface is the second side surface, the adapter transmits and receives the transmission and reception. A base portion facing the surface or the back surface is directly or indirectly connected to the base portion, and a first support portion in contact with the first side surface is directly or indirectly connected to the base portion. A second support portion that comes into contact with the second side surface is provided, and the radar device is sandwiched between the first support portion and the second support portion, and the first support portion is the first side surface. The radar device has a connecting portion whose end is directly or indirectly connected to the base portion, and a base portion which is connected to the connecting portion and extends in a direction approaching the base portion from the base portion. The tip is a free end when the radar device is removed, and a tongue piece that presses the first side surface toward the second support portion when the radar device is attached is provided.

Further, the radar unit according to the present invention includes an adapter according to the present invention and a radar device held by the adapter.

Further, the vehicle according to the present invention includes a radar unit according to the present invention.

In the adapter according to the present invention, when the radar device is attached to the adapter, the tongue piece of the first support portion presses the radar device toward the second support portion. That is, when the radar device is inserted between the tongue piece of the first support portion and the second support portion, the tongue piece is pushed in the direction away from the second support portion, and the first support portion is elastically deformed. Then, the tongue piece of the first support portion presses the radar device toward the second support portion by the reaction force generated in the first support portion when the first support portion is elastically deformed. As a result, the adapter according to the present invention holds the radar device by sandwiching the radar device between the tongue piece of the first support portion and the second support portion.

As described above, in the adapter according to the present invention, the radar device is held by the reaction force generated by the elastic deformation of the first support portion. That is, in the adapter according to the present invention, not only the tongue piece but also the connecting portion of the first support portion is elastically deformed. Therefore, the load that the tongue piece is pushed by the radar device is received not only by the tongue piece but also by the connecting portion of the first support portion. That is, the adapter according to the present invention can receive the load of the tongue piece being pushed by the radar device in a longer range than the conventional resin adapter. Therefore, the adapter according to the present invention can suppress the occurrence of stress concentration when the radar device is held by the adapter. Therefore, the adapter according to the present invention can suppress the occurrence of the creep phenomenon at the first support portion and suppress the decrease in the holding force of the radar device as compared with the conventional resin adapter.

The radar unit 3 includes a radar device 60 having a substantially rectangular parallelepiped shape. Further, the radar unit 3 includes a resin adapter 100 that holds the radar device 60. Hereinafter, the detailed configuration of the adapter 100 will be described. In explaining the adapter 100, each part of the radar device 60 is defined as follows. The surface facing the transmission / reception surface 65 is the back surface 66. One of the side surfaces connecting the transmission / reception surface 65 and the back surface 66 is referred to as a first side surface 61. The first side surface 61 is a side surface of the adapter 100 that comes into contact with the first support portion 20 described later. When the radar device 60 is held by the adapter 100 attached to the mounting portion of the motorcycle 1, the first side surface 61 becomes the upper surface of the radar device 60. Further, among the side surfaces connecting the transmission / reception surface 65 and the back surface 66, the side surface facing the first side surface 61 is referred to as the second side surface 62. The second side surface 62 is a side surface of the adapter 100 that comes into contact with the second support portion 40 described later. When the radar device 60 is held by the adapter 100 attached to the mounting portion of the motorcycle 1, the second side surface 62 becomes the lower surface of the radar device 60. Further, among the side surfaces connecting the transmission / reception surface 65 and the back surface 66, one of the side surfaces connecting the first side surface 61 and the second side surface 62 is referred to as the third side surface 63. Further, among the side surfaces connecting the transmission / reception surface 65 and the back surface 66, the side surface facing the third side surface 63 is referred to as the fourth side surface 64. In the case of the present embodiment, the left side surface is the third side surface 63, and the right side surface is the fourth side surface 64.

The adapter 100 includes a base portion 10, a first support portion 20, and a second support portion 40. The adapter 100 has a configuration in which the radar device 60 is sandwiched between the first support portion 20 and the second support portion 40 to hold the radar device 60.

The base portion 10 has, for example, a substantially rectangular parallelepiped plate shape. When the radar device 60 is held by the adapter 100, the base portion 10 faces the back surface 66 of the radar device 60. The radar device 60 may be held by the adapter 100 so that the transmission / reception surface 65 of the radar device 60 and the base portion 10 face each other.

The first support portion 20 is a member that comes into contact with the first side surface 61 of the radar device 60 when the radar device 60 is held by the adapter 100. The end of the first support portion 20 is connected to the base portion 10. That is, the first support portion 20 is directly connected to the base portion 10. In the present embodiment, the end portion of the first support portion 20 is connected to the vicinity of the upper end portion of the base portion 10. Further, the first support portion 20 projects from the connection portion with the base portion 10 toward the radar device 60.

Explaining the first support portion 20 in more detail, the first support portion 20 includes a connecting portion 21 and a tongue piece 31. The end of the connecting portion 21 is connected to the base portion 10. That is, the end of the connecting portion 21 is directly connected to the base portion 10. When the radar device 60 is held by the adapter 100, the connecting portion 21 faces the first side surface 61 of the radar device 60, but does not contact the first side surface 61 of the radar device 60. Further, in the present embodiment, the connecting portion 21 is formed in a substantially U-shape in a plan view. That is, the connecting portion 21 includes two ends (end 22 and end 23) connected to the base 10 on both sides of the tongue piece 31.

The tongue piece 31 has a base portion 32 connected to the connecting portion 21, and extends from the base portion 32 in a direction approaching the base portion 10. Further, in a state where the radar device 60 is not held by the adapter 100, the tip 33 of the tongue piece 31 is a free end. In other words, when the radar device 60 is removed from the adapter 100, the tip 33 of the tongue piece 31 is a free end. Further, in a state where the radar device 60 is held by the adapter 100, the tongue piece 31 presses the first side surface 61 of the radar device 60 toward the second support portion 40. In other words, when the radar device 60 is attached to the adapter 100, the tongue piece 31 presses the first side surface 61 of the radar device 60 toward the second support portion 40. As shown in FIGS. 5 and 6, in the present embodiment, the tongue piece 31 is provided with a contact portion 34 near the tip end 33, which is a contact point with the first side surface 61 of the radar device 60. As shown in FIG. 6, when the radar device 60 is held by the adapter 100, the tongue piece 31 presses the first side surface 61 of the radar device 60 with the contact portion 34.

The first support portion 20 according to the present embodiment is formed by folding the tongue piece 31 at a substantially central portion of the connecting portion 21. However, the position of the tongue piece 31 is an example. The tongue piece 31 may be formed by folding back at a position other than the central portion of the connecting portion 21. Further, the first support portion 20 may include a plurality of tongue pieces 31. Further, in the present embodiment, both the end portion 22 and the end portion 23 are connected to the base portion 10, but even if only one of the end portion 22 and the end portion 23 is connected to the base portion 10. Good.

Here, in the present embodiment, the moment of inertia of area of each portion of the first support portion 20 is set as follows.

In the connecting portion 21, the intermediate portion between the connecting portion of the tongue piece 31 with the base portion 32 and the end portion connected to the base portion 10 is referred to as the connecting portion side intermediate portion 24. When the connecting portion side intermediate portion 24 is defined in this way, in the connecting portion 21 according to the present embodiment, the moment of inertia of area of the connecting portion side intermediate portion 24 is the end portion connected to the base portion 10. It is smaller than the moment of inertia of area. In the connecting portion 21 according to the present embodiment, the end portion 22 and the end portion 23 are connected to the base portion 10. Therefore, in the present embodiment, the sum of the moment of inertia of area of the end portion 22 and the moment of inertia of area of the end portion 23 is the moment of inertia of area of the end portion connected to the base portion 10. Further, in the connecting portion 21 according to the present embodiment, since the end portion 22 and the end portion 23 are connected to the base portion 10, the two ranges are the connecting portion side intermediate portion 24. Specifically, as illustrated by the alternate long and short dash line in FIG. 5, the first portion between the connecting portion of the tongue piece 31 with the base portion 32 and the end portion 22 is one of the intermediate portions 24 on the connecting portion side. It becomes the intermediate portion 24a on the connecting portion side. Further, as illustrated by the alternate long and short dash line in FIG. 5, between the connecting portion of the tongue piece 31 with the base portion 32 and the end portion 23 is the second connecting portion side which is one of the connecting portion side intermediate portions 24. It becomes the middle part 24b. In the case of the present embodiment, the sum of the moment of inertia of area of the first connecting portion side intermediate portion 24a and the moment of inertia of area of the second connecting portion side intermediate portion 24b is the geometrical moment of inertia of the connecting portion side intermediate portion 24. It becomes.

In the tongue piece 31, the intermediate portion between the contact portion 34 and the base portion 32 is referred to as the intermediate portion 35 on the tongue piece side. When the halfway portion 35 on one side of the tongue is defined in this way, the moment of inertia of area of the halfway portion 35 on one side of the tongue is smaller than the moment of inertia of area of the base 32. Further, in the present embodiment, the moment of inertia of area of the base portion 32 is smaller than the moment of inertia of area of the intermediate portion 24 on the connecting portion side.

The second support portion 40 is a member that comes into contact with the second side surface 62 of the radar device 60 when the radar device 60 is held by the adapter 100. The end of the second support portion 40 is connected to the base portion 10. That is, the second support portion 40 is directly connected to the base portion 10. In the present embodiment, the end portion of the second support portion 40 is connected to the vicinity of the lower end portion of the base portion 10. Further, the second support portion 40 projects from the connection portion with the base portion 10 toward the radar device 60.

In the present embodiment, the radar device 60 is provided with a connector 67 on the second side surface 62, which is used for wiring connection with a control device (not shown). Therefore, the second support portion 40 is formed with an opening 41 so that the second support portion 40 and the connector 67 do not interfere with each other. That is, when the adapter 100 holds the radar device 60, the connector 67 is inserted into the opening 41. A notch may be formed in the second support portion 40 instead of the opening 41 so that the second support portion 40 and the connector 67 do not interfere with each other.

Further, the adapter 100 according to the present embodiment includes a first side wall 45 and a second side wall 47 connected to the base portion 10. The first side wall 45 and the second side wall 47 project from the base portion 10 toward the radar device 60. The first side wall 45 faces the third side surface 63 of the radar device 60 when the radar device 60 is held by the adapter 100. The second side wall 47 faces the fourth side surface 64 of the radar device 60 when the radar device 60 is held by the adapter 100. The distance between the first side wall 45 and the second side wall 47 is shorter than the distance between the third side surface 63 and the fourth side surface 64 of the radar device 60. Therefore, in the adapter 100 according to the present embodiment, when the radar device 60 is held by the adapter 100, the radar device 60 is sandwiched between the first support portion 20 and the second support portion 40, and the radar device 60 is sandwiched between the first side wall 45 and the first side wall 45. The radar device 60 is further sandwiched between the second side wall 47 and the second side wall 47. By sandwiching the radar device 60 between the first support portion 20 and the second support portion 40, the radar device 60 can be sufficiently held by the adapter 100. However, by further sandwiching the radar device 60 between the first side wall 45 and the second side wall 47, the radar device 60 can be held more stably by the adapter 100.

The third side surface 63 of the radar device 60 is provided with a convex portion (not shown) that protrudes toward the first side wall 45, and the fourth side surface 64 of the radar device 60 projects toward the second side wall 47. A convex portion that cannot be shown may be provided. This convex portion is composed of, for example, a pin or the like. The distance between the first side wall 45 and the second side wall 47 is shorter than the distance between the tip of the convex portion of the third side surface 63 and the tip of the convex portion of the fourth side surface 64.

Here, the adapter 100 can also hold a plurality of radar devices 60 having different positions of the connectors 67 by the same adapter 100.

FIG. 7 is a perspective view showing another example of the radar unit according to the embodiment of the present invention.
The radar device 60 shown in FIG. 7 is provided with a connector 67 on the third side surface 63. Even when holding such a radar device 60, the adapter 100 shown in FIGS. 2 to 6 can be used as long as the adapter 100 and the connector 67 do not interfere with each other. The adapter 100 shown in FIG. 7 has a first side wall 45 facing the third side surface 63 as shown in FIGS. 3 and 4 in order to avoid interference with the connector 67 provided on the third side surface 63. A notch 46 is formed in the.

Further, the adapter 100 according to the present embodiment includes an adjustment mechanism for adjusting the angle of the detection axis of the radar device 60 with respect to the attachment portion of the motorcycle 1. Specifically, the adapter 100 includes three female screw portions 12 and three adjusting bolts 70 as an adjusting mechanism. Each of the female screw portions 12 is formed in the base portion 10 so as to penetrate in the front-rear direction, for example. Each of the adjusting bolts 70 is formed with a male screw portion 71 that meshes with the female screw portion 12. Further, at the end of the male screw portion 71, a tool connecting portion 72 having a cross-sectional shape of, for example, a polygonal shape is provided. That is, the male screw portion 71 of the adjustment bolt 70 is screwed into the female screw portion 12 of the base portion 10, the tool is connected to the tool connection portion 72, and the adjustment bolt 70 is turned. It can move relative to the base portion 10 in the penetrating direction. The female screw portion 12 may be a tapping screw formed when the male screw portion 71 is inserted, or may be formed before the male screw portion 71 is inserted. Good.

Further, the end portion of the adjusting bolt 70 opposite to the tool connecting portion 72 is rotatably and angle-changeably attached to the attachment portion of the motorcycle 1. As long as the adjusting bolt 70 is rotatable and angle-changeable with respect to the mounting portion of the motorcycle 1, the mounting configuration of the end portion of the adjusting bolt 70 and the mounting portion of the motorcycle 1 is not particularly limited. Universal joints of various configurations are known in which two connecting parts are rotatably and angle-changeably connected. For example, the end portion of the adjusting bolt 70 may be rotatably and angle-changeably attached to the attachment portion of the motorcycle 1 by using such a known connection configuration of the universal joint.

In the present embodiment, the end portion of the adjustment bolt 70 is rotatably and angle-changeably attached to the attachment portion of the motorcycle 1 by using the attachment component 80 constituting the universal joint together with the adjustment bolt 70. The mounting component 80 may be an accessory component of the adapter 100 or an accessory component of the motorcycle 1. Specifically, at the end of the adjusting bolt 70 on the side opposite to the tool connecting portion 72, a spherical head 73 having a partially spherical outer peripheral portion is formed. Further, the mounting component 80 includes a holding portion 81 that holds the ball head 73 of the adjusting bolt 70 so as to be rotatable and angle-changeable. The configuration in which the holding portion 81 holds the ball head 73 is not particularly limited. As a configuration in which the holding portion 81 holds the sphere head 73, various known configurations that hold the sphere head rotatably and angle-changeably in the universal joint can be used.

The male threaded portion 71 of the adjusting bolt 70 is screwed into each of the female threaded portions 12 of the base portion 10, and the same number of mounting parts 80 as the adjusting bolt 70 are attached to the mounting portion of the motorcycle 1 to the holding portion 81 of each mounting component 80. By holding the ball head 73 of each adjusting bolt 70, the adapter 100 is attached to the attachment portion of the motorcycle 1. The mounting configuration of the mounting component 80 to the mounting portion of the motorcycle 1 is not particularly limited, but in the present embodiment, the mounting configuration is as follows. The mounting component 80 includes a first flange portion 82 and a second flange portion 83 having different heights. The mounting component 80 is mounted on the mounting portion of the motorcycle 1 by sandwiching the plate member of the mounting portion of the motorcycle 1 between the first flange portion 82 and the second flange portion 83.

In the state where the adapter 100 is attached to the mounting portion of the motorcycle 1, by connecting the tool to the tool connecting portion 72 and turning each adjusting bolt 70, the adapter 100 and the motorcycle 1 are placed at the positions of the adjusting bolts 70. The distance to the mounting part can be changed. Thereby, the angle of the adapter 100 with respect to the mounting portion of the motorcycle 1 can be adjusted. That is, the angle of the detection axis of the radar device 60 held by the adapter 100 can be adjusted with respect to the mounting portion of the motorcycle 1.

As shown in FIGS. 2 to 4, when the male screw portion 71 of the adjustment bolt 70 is screwed into the female screw portion 12 from the rear of the base portion 10, the adapter 100 is arranged in front of the mounting portion of the motorcycle 1. The tool connecting portion 72 of the adjusting bolt 70 protrudes forward of the base portion 10. Therefore, the angle of the adapter 100 with respect to the mounting portion of the motorcycle 1 is adjusted from the front of the adapter 100. However, the method of adjusting the angle of the adapter 100 from the front is an example.

FIG. 8 is an assembly perspective view showing an adapter according to an embodiment of the present invention.
As shown in FIG. 8, when the male screw portion 71 of the adjustment bolt 70 is screwed into the female screw portion 12 from the front of the base portion 10, the adapter 100 is arranged behind the mounting portion of the motorcycle 1 and the adjustment bolt 70 The tool connecting portion 72 protrudes to the rear of the base portion 10. Therefore, the angle of the adapter 100 with respect to the mounting portion of the motorcycle 1 can be adjusted from the rear of the adapter 100.

That is, the adapter 100 according to the present embodiment adjusts the angle of the adapter 100 with respect to the mounting portion of the motorcycle 1 from both the front and rear sides of the adapter 100, in other words, from both the front and rear sides of the radar device 60. Can be done. Depending on the mounting part of the motorcycle 1 and the structure around the mounting part, the installation space of the adapter 100 and the radar device 60 can be reduced by arranging the adapter 100 in front of the mounting part, and the adapter 100 is placed behind the mounting part. In some cases, the installation space of the adapter 100 and the radar device 60 can be reduced by arranging them. Since the adapter 100 according to the present embodiment can adjust the angle of the adapter 100 with respect to the mounting portion of the motorcycle 1 from both the front and rear sides of the adapter 100, the installation space of the adapter 100 and the radar device 60 is reduced. be able to. That is, the installation space of the radar unit 3 can be reduced.

The adapter 100 according to the present embodiment includes three female screw portions 12 and three adjusting bolts 70. However, the number of female screw portions 12 is not limited to three, and the number of adjusting bolts 70 is not limited to three. If the distance between the adapter 100 and the mounting portion of the motorcycle 1 can be adjusted at at least three places, the angle of the adapter 100 with respect to the mounting portion of the motorcycle 1 can be adjusted. Therefore, the number of female screw portions 12 may be four or more as long as there are at least three. Similarly, the number of adjusting bolts 70 may be four or more as long as there are at least three.

Further, in the adapter 100 according to the present embodiment, when the adjusting bolt 70 is attached to the female screw portion 12, each of the adjusting bolt 70 is arranged on the outer peripheral side of the radar device 60. With such a configuration, the adapter 100 with respect to the attachment portion of the motorcycle 1 can be used both in the state before the adapter 100 holds the radar device 60 and in the state after the adapter 100 holds the radar device 60. The angle can be adjusted. Therefore, the work of adjusting the angle of the adapter 100 with respect to the mounting portion of the motorcycle 1 becomes easy.

Further, the adapter 100 according to the present embodiment is formed with a fixing female screw portion 13 into which a fixing bolt inserted into a through hole of a mounting portion of the motorcycle 1 is screwed. Therefore, when it is not necessary to adjust the angle of the adapter 100 with respect to the mounting portion of the motorcycle 1, the adapter 100 can be mounted on the mounting portion of the motorcycle 1 without using the adjusting bolt 70. Therefore, when it is not necessary to adjust the angle of the adapter 100 with respect to the mounting portion of the motorcycle 1, the adapter 100 according to the present embodiment is made smaller than the adapter in which the female screw portion 13 for fixing is not formed. be able to. The number of fixing female screw portions 13 is not particularly limited, but in the present embodiment, three fixing female screw portions 13 are formed.

<How to hold the radar device with the adapter>
Subsequently, a method of holding the radar device 60 with the adapter 100 will be described.
First, the back surface 66 of the radar device 60 is brought closer to the base portion 10 of the adapter 100, and the radar device 60 is inserted between the tongue piece 31 of the first support portion 20 and the second support portion 40. Here, in the state before the radar device 60 is inserted between the tongue piece 31 of the first support portion 20 and the second support portion 40, the tongue piece 31 of the first support portion 20 and the second support portion 40 The distance between them is shorter than the distance between the first side surface 61 and the second side surface 62 of the radar device 60. In other words, when the radar device 60 is removed from the adapter 100, the distance between the tongue piece 31 of the first support portion 20 and the second support portion 40 is the distance between the first side surface 61 and the second side surface of the radar device 60. It is shorter than the distance to 62. Therefore, when the radar device 60 is inserted between the tongue piece 31 of the first support portion 20 and the second support portion 40, the tongue piece 31 is moved from the second support portion 40 by the first side surface 61 of the radar device 60. Pushed away.

As a result, the tongue piece 31 is elastically deformed between the base portion 32 and the contact portion 34. Further, the base portion 32 of the tongue piece 31 is connected to the connecting portion 21 of the first support portion 20. Therefore, when the radar device 60 is inserted between the tongue piece 31 of the first support portion 20 and the second support portion 40, the connecting portion 21 is connected to the connecting portion 21 via the tongue piece 31 by the first side surface 61 of the radar device 60. It is pushed away from the second support portion 40. Therefore, when the radar device 60 is inserted between the tongue piece 31 of the first support portion 20 and the second support portion 40, the connecting portion 21 is also elastically deformed. That is, by inserting the radar device 60 between the tongue piece 31 of the first support portion 20 and the second support portion 40, the reaction force generated when the tongue piece 31 undergoes the above-mentioned elastic deformation and the connecting portion. The reaction force generated when the 21 undergoes the above-mentioned elastic deformation acts on the first side surface 61 of the radar device 60. As a result, the radar device 60 is sandwiched between the tongue piece 31 of the first support portion 20 and the second support portion 40, and the radar device 60 is held by the adapter 100.

<Effect of adapter>
The adapter 100 according to the present embodiment is a resin adapter that is attached to the mounting portion of the vehicle and holds the radar device 60. The adapter 100 includes a base portion 10 facing the transmission / reception surface 65 or the back surface 66 of the radar device 60, a first support portion 20 connected to the base portion 10 and in contact with the first side surface 61 of the radar device 60, and a base portion. It is provided with a second support portion 40, which is connected to the 10 and is in contact with the second side surface 62 of the radar device 60. The adapter 100 has a configuration in which the radar device 60 is sandwiched between the first support portion 20 and the second support portion 40. Further, the first support portion 20 includes a connecting portion 21 and a tongue piece 31. The connecting portion 21 faces the first side surface 61 of the radar device 60, and the end portion 22 and the end portion 23 are connected to the base portion 10. The tongue piece 31 has a base portion 32 connected to the connecting portion 21 and extends from the base portion 32 in a direction approaching the base portion 10. Further, the tip 33 of the tongue piece 31 is a free end when the radar device 60 is removed from the adapter 100. Further, the tongue piece 31 presses the first side surface 61 of the radar device 60 toward the second support portion 40 in a state where the radar device 60 is attached to the adapter 100.

In conventional resin adapters, the base of the tongue piece that presses the radar device is directly connected to the base. Then, in the conventional resin adapter, the radar device is held by the reaction force generated by the elastic deformation between the portion of the tongue piece in contact with the radar device and the base portion. That is, in the conventional resin adapter, when the radar device is held by the adapter, the load pushed by the radar device is between the portion of the tongue piece in contact with the upper surface of the radar device and the base. I received it at. At this time, the distance between the portion of the tongue piece in contact with the radar device and the base is short. Therefore, in the conventional resin adapter, when the radar device is held by the adapter, stress concentration tends to occur at the base portion where the tongue piece is fixed. Therefore, in the conventional resin adapter, when time elapses while holding the radar device, a creep phenomenon occurs at the base of the tongue piece, and the holding force of the radar device tends to decrease. When the holding force of the radar device by the adapter is reduced, the radar device is likely to come off from the adapter, for example, when the vehicle on which the adapter and the radar device are mounted vibrates. Further, for example, when the holding force of the radar device by the adapter decreases, the detection axis of the radar device may shift when the vehicle on which the adapter and the radar device are mounted vibrates.

On the other hand, as described above, in the adapter 100 according to the present embodiment, when the radar device 60 is held, not only the tongue piece 31 but also the connecting portion 21 of the first support portion 20 is elastically deformed. Therefore, the load that the tongue piece 31 is pushed by the radar device 60 is received not only by the tongue piece 31 but also by the connecting portion 21. That is, the adapter 100 according to the present embodiment can receive the load that the tongue piece 31 is pushed by the radar device 60 in a longer range than the conventional resin adapter. Therefore, the adapter 100 according to the present embodiment can suppress the occurrence of stress concentration at the base portion 32, which is a fixed portion of the tongue piece 31, when the radar device 60 is held by the adapter 100. Further, in the adapter 100 according to the present embodiment, when the radar device 60 is held by the adapter 100, stress concentration occurs at the end 22 and the end 23 of the connecting portion 21, which is a fixed portion of the first support portion 20. It can also be suppressed. Therefore, the adapter 100 according to the present embodiment can suppress the occurrence of the creep phenomenon in the first support portion 20 and suppress the decrease in the holding power of the radar device 60 as compared with the conventional resin adapter. Therefore, the adapter 100 according to the present embodiment is compared with the conventional resin adapter, for example, when the vehicle on which the radar unit 3 according to the present embodiment vibrates, the adapter 100 to the radar device 60 Can be suppressed from coming off. Further, for example, the adapter 100 according to the present embodiment has a detection axis of the radar device 60 when the vehicle on which the radar unit 3 according to the present embodiment vibrates, as compared with the conventional resin adapter. It is possible to suppress the deviation.

Preferably, in the connecting portion 21, the moment of inertia of area of the intermediate portion 24 on the connecting portion side is smaller than the moment of inertia of area of the end portion connected to the base portion 10. With such a configuration, the connecting portion 21 is more likely to be elastically deformed more uniformly, and it is possible to further suppress the occurrence of stress concentration at the end portion 22 and the end portion 23 of the connecting portion 21. That is, with such a configuration, it is possible to further suppress a decrease in the holding power of the radar device 60 in the adapter 100.

Preferably, in the tongue piece 31, the moment of inertia of area of the middle portion 35 on the side of the tongue piece is smaller than the moment of inertia of area of the base portion 32. With such a configuration, the tongue piece 31 is more likely to be elastically deformed more uniformly, and it is possible to further suppress the occurrence of stress concentration on the base portion 32 of the tongue piece 31. That is, with such a configuration, it is possible to further suppress a decrease in the holding power of the radar device 60 in the adapter 100. More preferably, the moment of inertia of area of the base 32 of the tongue piece 31 is smaller than the moment of inertia of area 24 of the connecting portion 21 on the connecting portion side. With such a configuration, the entire first support portion 20 is likely to be elastically deformed uniformly, and it is possible to further suppress the occurrence of stress concentration in the first support portion 20. That is, with such a configuration, it is possible to further suppress a decrease in the holding power of the radar device 60 in the adapter 100.

Preferably, the vehicle provided with the radar unit 3 according to the present embodiment is a motorcycle 1. If the holding power of the radar device 60 is reduced in the adapter 100, the radar device 60 may rattle in the adapter 100 and noise may be generated when the vehicle on which the radar unit 3 is mounted moves up and down. Here, in a four-wheeled vehicle, the driver rides in the room and the radar unit 3 is arranged in the engine room or the like. Therefore, in a four-wheeled vehicle, the driver is not so concerned about the noise caused by the rattling of the radar device 60 in the adapter 100. On the other hand, the motorcycle 1 does not have a room for the driver to ride. Therefore, in the motorcycle 1, the noise caused by the rattling of the radar device 60 in the adapter 100 is easily heard by the driver. Further, the motorcycle 1 has a shorter wheelbase and is easier to move up and down than the motorcycle. Further, in the motorcycle 1, since both the engine and the radar unit 3 are attached to the frame 2, the vibration of the engine is easily transmitted to the radar unit 3. That is, the motorcycle 1 is more likely to generate noise due to the rattling of the radar device 60 in the adapter 100 than the motorcycle. Therefore, it is preferable that the radar unit 3 according to the present embodiment, which can suppress a decrease in the holding power of the radar device 60, is provided in the motorcycle 1 in which noise due to rattling of the radar device 60 is likely to occur.

At the connection point with, the angle between the edge portion of the connecting portion 21 and the edge portion of the tongue piece 31 can be increased. Therefore, the adapter 100 in which the first support portion 20 is indirectly connected to the base portion 10 has a tongue piece 31 as compared with the adapter 100 in which the first support portion 20 is directly connected to the base portion 10. It is possible to further suppress the occurrence of stress concentration at the base portion 32, which is a fixed portion.

On the other hand, the adapter 100 in which the first support portion 20 is directly connected to the base portion 10 has the following effects as compared with the adapter 100 in which the first support portion 20 is indirectly connected to the base portion 10.
