Description

Adapter, radar unit and vehicle

Technical Field

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

Background

Conventionally, some vehicles such as a motorcycle are mounted with a radar device using a laser radar, a millimeter wave radar, or the like for detecting an obstacle. The radar device is used for, for example, an ACC system (adaptive cruise control system), a Stop & Go system (congestion tracking system), a vehicle-to-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 an attachment portion of a vehicle. In patent document 1, the adapter is referred to as a support member. Further, the adapter of patent document 1 is made of metal, but in recent years, in consideration of the attachment property of the radar device to the adapter, etc., an adapter made of resin has also been proposed.

A conventional resin adapter will be described. When the surface of the radar device facing the transmission/reception surface is defined as the rear surface, the conventional resin adapter includes a base portion facing the rear surface of the radar device. Further, the conventional resin adapter includes a support portion for supporting a lower surface of the radar device, and a tongue piece for pressing an upper surface of the radar device against the support portion. In a tongue piece of a conventional resin adapter, a base portion and a base portion are directly connected to each other, and extend toward a transmission/reception surface of a radar device so as to face an upper surface of the radar device. Further, in a state where 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 a radar device is held in a conventional resin adapter, the rear surface of the radar device is brought close to a base portion of the adapter, and the radar device is inserted between a tongue piece and a support portion. Thereby, a portion of the tongue piece that contacts the upper surface of the radar device is pushed upward. In other words, a portion of the tongue piece that contacts the upper surface of the radar device is pushed in a direction away from the support portion. 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 base and a portion that contacts the upper surface of the radar device. When elastically deformed in this way, the reaction force generated in the tongue piece acts as a force that presses the upper surface of the radar device downward. That is, the radar device is pressed in the direction of the support portion by the reaction force of the tongue piece. In this way, the conventional resin adapter sandwiches the radar device in the vertical direction by the support portion and the tongue piece, and holds the radar device.

Patent document 1: japanese patent laid-open 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 that contacts 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, a load of the tongue piece pushed by the radar device is received between a portion of the tongue piece that contacts the upper surface of the radar device and the base portion. At this time, the distance between the portion of the tongue piece that contacts the upper surface of the radar device and the base is short. Therefore, when the conventional resin adapter is used to hold the radar device on the adapter, stress concentration tends to occur at the base portion, which is the fixing portion of the tongue piece. Therefore, the conventional resin adapter has the following problems: when a certain period of time passes while the radar device is held, a creep phenomenon occurs at the base of the tongue piece, and the holding force of the radar device is reduced.

Disclosure of Invention

The present invention has been made in view of the above-described problems, and a first object of the present invention is to provide an adapter made of resin, which is used when a radar device is mounted on a vehicle, and which can suppress a reduction in holding force of the radar device compared to the conventional adapter. A second object of the present invention is to provide a radar unit including such an adapter. A third object of the present invention is to provide a vehicle including such a radar unit.

An adapter according to the present invention is a resin adapter which is mounted on a mounting portion of a vehicle, holds a radar device, and includes, in a case where a surface of the radar device which faces a transmitting/receiving surface is a rear surface, one of side surfaces of the radar device which connects the transmitting/receiving surface and the rear surface is a first side surface, and the other of the side surfaces of the radar device which faces the first side surface is a second side surface: a base portion facing the transmitting/receiving surface or the rear surface; a first support part directly or indirectly connected to the base part and contacting the first side surface; a second support part directly or indirectly connected to the base part and in contact with the second side surface; the radar apparatus is sandwiched between the first support part and the second support part, and the first support part includes: a coupling portion facing the first side surface and having an end portion directly or indirectly connected to the base portion; and a tongue piece having a base portion connected to the connection portion and extending from the base portion in a direction approaching the base portion, a distal end serving as a free end in a state where the radar device is removed, and the tongue piece pressing the first side surface toward the second support portion in a state where the radar device is attached.

The radar unit of the present invention includes the adapter of the present invention and a radar device held by the adapter.

The vehicle of the present invention is provided with the radar unit of the present invention.

In the adapter according to the present invention, the tongue piece of the first support portion presses the radar device toward the second support portion in a state where the radar device is attached to the adapter. 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 a direction away from the second support portion, and the first support portion is elastically deformed. When the first support portion is elastically deformed, the tongue piece of the first support portion presses the radar device in the direction of the second support portion by a reaction force generated in the first support portion. Thus, the adapter of 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 of the present invention, the radar device is held by the reaction force generated by the elastic deformation of the first support portion. That is, the adapter of the present invention elastically deforms not only the tongue piece but also the coupling portion of the first support portion. Therefore, not only the tongue piece but also the coupling portion of the first support portion receives the load of the tongue piece pushed by the radar device. That is, the adapter of the present invention can receive the load of the tongue piece pushed by the radar device over a longer range than the conventional adapter made of resin. Therefore, the adapter of the present invention can suppress the occurrence of stress concentration when the radar device is held by the adapter. Therefore, the adapter of the present invention can suppress the occurrence of the creep phenomenon in the first support portion and suppress the reduction in the holding force of the radar device, as compared with the conventional resin adapter.

Fig. 4 is an assembled perspective view showing an adapter of the embodiment of the present invention. Fig. 5 is a view showing the first support portion of the adapter according to the embodiment of the present invention, and is a view of the first support portion as viewed from the direction of arrow a in fig. 3. Further, fig. 6 is a sectional view B-B of fig. 2.

The radar unit 3 includes a substantially rectangular parallelepiped radar device 60. The radar unit 3 further includes a resin adapter 100 that holds the radar device 60. The detailed structure of the adapter 100 will be described below. In describing the adapter 100, each part of the radar device 60 is defined as follows. The surface opposite to the transmission/reception surface 65 is taken as a rear surface 66. One of the side surfaces connecting the transmission/reception surface 65 and the rear surface 66 is taken as the first side surface 61. The first side surface 61 is a side surface that contacts a later-described first support portion 20 of the adapter 100. When the radar device 60 is held by the adapter 100 attached to the attachment portion of the motorcycle 1, the first side surface 61 becomes the upper surface of the radar device 60. Further, of the side surfaces connecting the transmission/reception surface 65 and the rear surface 66, the side surface opposite to the first side surface 61 is taken as the second side surface 62. The second side surface 62 is a side surface that contacts a later-described second support portion 40 of the adapter 100. When the radar device 60 is held by the adapter 100 attached to the attachment portion of the motorcycle 1, the second side surface 62 becomes the lower surface of the radar device 60. Further, of the side surfaces connecting the transmission/reception surface 65 and the rear surface 66, one of the side surfaces connecting the first side surface 61 and the second side surface 62 is taken as the third side surface 63. Further, of the side surfaces connecting the transmission/reception surface 65 and the rear surface 66, the side surface opposite to the third side surface 63 is taken as the fourth side surface 64. In the case of the present embodiment, the left side surface becomes the third side surface 63, and the right side surface becomes the fourth side surface 64.

The adapter 100 includes: base portion 10, first support portion 20, second support portion 40. The adapter 100 is configured as follows: the radar device 60 is held by sandwiching the radar device 60 between the first support part 20 and the second support part 40.

The base portion 10 is, for example, a plate shape having a substantially rectangular parallelepiped shape. When the radar device 60 is held by the adapter 100, the base portion 10 is opposed to the rear surface 66 of the radar device 60. Further, the radar device 60 may be held by the adapter 100 so that the transmission/reception surface 65 of the radar device 60 faces the base portion 10.

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 of the first support portion 20 is connected to the vicinity of the upper end of the base portion 10. The first support portion 20 projects from a connection portion with the base portion 10 toward the radar device 6.

To describe the first support portion 20 in more detail, the first support portion 20 includes the coupling portion 21 and the tongue piece 31. The end of the coupling portion 21 is connected to the base portion 10. That is, the end of the coupling portion 21 is directly connected to the base portion 10. When the radar device 60 is held by the adapter 100, the connection 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. In the present embodiment, the coupling portion 21 is formed in a substantially U shape in a plan view. That is, the coupling portion 21 includes two end portions (end portion 22 and end portion 23) connected to the base portion 10 on both sides of the tongue piece 31.

Tongue 31 has base portion 32 connected to coupling portion 21, and extends from base portion 32 in a direction approaching base portion 10. In a state where the radar device 60 is not held by the adapter 100, the tip 33 of the tongue piece 31 becomes a free end. In other words, in a state where 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, in a state where the adapter 100 is mounted with the radar device 60, the tongue piece 31 presses the first side surface 61 of the radar device 60 toward the second support portion 40. As shown in fig. 5 and 6, in the present embodiment, the tongue piece 31 is provided with a contact portion 34 in the vicinity of the tip 33, which is a contact portion with the first side surface 61 of the radar device 60. As shown in fig. 6, 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 with the contact portion 34.

The tongue piece 31 of the first support portion 20 of the present embodiment is formed by being folded back at a substantially central portion of the coupling portion 21. However, this position of the tongue 31 is an example. The tongue piece 31 may be folded back at a position other than the central portion of the coupling portion 21. The first support portion 20 may include a plurality of tongue pieces 31. In the present embodiment, both the

end portions

22 and 23 are connected to the base portion 10, but only one of the

end portions

22 and 23 may be connected to the base portion 10.

In the present embodiment, the second moment of area of each part of the first support section 20 is set as follows.

In the coupling portion 21, a middle portion between a coupling portion with the base portion 32 of the tongue piece 31 and an end portion coupled with the base portion 10 is defined as a coupling portion side middle portion 24. When the connecting portion side intermediate portion 24 is defined in this way, in the connecting portion 21 of the present embodiment, the moment of area inertia of the connecting portion side intermediate portion 24 is smaller than the moment of area inertia of the end portion connected to the base portion 10. The end 22 and the end 23 of the coupling portion 21 of the present embodiment are connected to the base portion 10. Therefore, in the present embodiment, the sum of the moment of inertia of the cross section of the end portion 22 and the moment of inertia of the cross section of the end portion 23 is the moment of inertia of the cross section of the end portion connected to the base portion 10. In the coupling portion 21 of the present embodiment, the end portion 22 and the end portion 23 are connected to the base portion 10, and therefore, the two ranges become the coupling portion side intermediate portion 24. Specifically, as shown by the two-dot chain line in fig. 5, a first connecting portion side intermediate portion 24a, which is one of the connecting portion side intermediate portions 24, is provided between the end portion 22 and the connecting portion with the base portion 32 of the tongue piece 31. As shown by the two-dot chain line in fig. 5, a second connecting portion side intermediate portion 24b, which is one of the connecting portion side intermediate portions 24, is provided between the end portion 23 and the connecting portion with the base portion 32 of the tongue piece 31. In the case of the present embodiment, the sum of the second moment of inertia of the first connecting portion side intermediate portion 24b and the second connecting portion side intermediate portion 24a becomes the second moment of inertia of the connecting portion side intermediate portion 24.

In the tongue 31, a middle portion between the contact portion 34 and the base portion 32 is a tongue-side middle portion 35. When the tongue-side intermediate portion 35 is defined in this way, the moment of area inertia of the tongue-side intermediate portion 35 is smaller than the moment of area inertia of the base portion 32. In the present embodiment, the sectional moment of inertia of the base portion 32 is smaller than the sectional moment of inertia of the connecting portion side intermediate portion 24.

The second support portion 40 is a member that is in 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, an 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 protrudes from a 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, the connector being used when wiring-connecting to a control device, not shown. Therefore, the opening 41 is formed in the second support portion 40 so that the second support portion 40 does not interfere with the connector 67. That is, when the radar device 60 is held by the adapter 100, the connector 67 is inserted into the opening 41. In addition, a cutout may be formed in second support portion 40 in place of opening 41 so that second support portion 40 does not interfere with connector 67.

The adapter 100 of the present embodiment includes a first sidewall 45 and a second sidewall 47 connected to the base portion 10. The first side wall 45 and the second side wall 47 protrude from the base portion 10 toward the radar device 60. When the radar device 60 is held by the adapter 100, the first side wall 45 is opposed to the third side surface 63 of the radar device 60. When the radar apparatus 60 is held by the adapter 100, the second side wall 47 is opposed to the fourth side surface 64 of the radar apparatus 60. 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, the adapter 100 of the present embodiment is configured to sandwich the radar device 60 between the first support portion 20 and the second support portion 40, and sandwich the radar device 60 between the first side wall 45 and the second side wall 47 when the radar device 60 is held by the adapter 100. 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.

Further, a convex portion, not shown, protruding toward the first side wall 45 may be provided on the third side surface 63 of the radar device 60, and a convex portion, not shown, protruding toward the second side wall 47 may be provided on the fourth side surface 64 of the radar device 60. The projection is formed of a pin or the like, for example. And, 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 hold a plurality of radar devices 60 having different positions of the connector 67 by the same adapter 100.

The radar device 60 shown in fig. 7 is provided with a connector 67 on the third side surface 63. Even in the case of holding such a radar device 60, the adapter 100 shown in fig. 2 to 6 can be used as long as the adapter 100 and the connector 67 do not interfere with each other. In the adapter 100 shown in fig. 7, in order to avoid interference with the connector 67 provided on the third side surface 63, as shown in fig. 3, 4, and the like, a notch 46 is formed in the first side wall 45 facing the third side surface 63.

The adapter 100 of the present embodiment is provided with an adjustment mechanism for adjusting the angle of the detection shaft of the radar device 60 with respect to the mounting 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 female screw portion 12 is formed in the base portion 10 so as to penetrate therethrough 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, a tool connection portion 72 having a polygonal cross-sectional shape, for example, is provided at an end portion of the male screw portion 71. That is, the male screw portion 71 of the adjuster bolt 70 is screwed into the female screw portion 12 of the base portion 10, and a tool is connected to the tool connecting portion 72 to rotate the adjuster bolt 70, whereby the adjuster bolt 70 can be moved relative to the base portion 10 in the direction in which the female screw portion 12 penetrates. The female screw portion 12 may be a self-tapping screw formed when the male screw portion 71 is inserted, or may be formed before the male screw portion 71 is inserted.

The end of the adjusting bolt 70 opposite to the tool connecting portion 72 is rotatably and angularly variably attached to the attachment portion of the motorcycle 1. The mounting structure of the end portion of the adjusting bolt 70 and the mounting portion of the motorcycle 1 is not particularly limited as long as the adjusting bolt 70 is rotatable and changeable in angle with respect to the mounting portion of the motorcycle 1. Universal joints of various structures in which two coupling members are coupled to each other so as to be rotatable and changeable in angle are known. For example, the end of the adjusting bolt 70 may be rotatably and angularly variably attached to the attachment portion of the motorcycle 1 using a known coupling structure of such a universal joint.

In the present embodiment, the mounting member 80 constituting the universal joint is used together with the adjusting bolt 70, and the end portion of the adjusting bolt 70 is rotatably and angularly variably mounted on the mounting portion of the motorcycle 1. The mounting part 80 may be an accessory part of the adapter 100 or an accessory part of the motorcycle 1. Specifically, a ball head 73 having a spherical outer peripheral portion is formed at an end of the adjusting bolt 70 opposite to the tool connecting portion 72. The mounting member 80 further includes a holding portion 81 for rotatably and angularly variably holding the ball portion 73 of the adjusting bolt 70. In addition, the structure of the holding portion 81 holding the ball portion 73 is not particularly limited. As the structure for holding the ball part 73 by the holding part 81, various known structures for rotatably holding the ball part and for variably holding the angle in the universal joint can be used.

The male screw portion 71 of the adjuster bolt 70 is screwed into each female screw portion 12 of the base portion 10, the same number of mounting members 80 as the number of the adjuster bolts 70 are mounted on the mounting portion of the motorcycle 1, and the head portion 73 of each adjuster bolt 70 is held by the holding portion 81 of each mounting member 80, whereby the adapter 100 is mounted on the mounting portion of the motorcycle 1. The mounting structure of the mounting member 80 to the mounting portion of the motorcycle 1 is not particularly limited, and in the present embodiment, the following mounting structure is adopted. The mounting member 80 includes a first collar portion 82 and a second collar portion 83 having different heights. The mounting member 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 a state where the adapter 100 is mounted on the mounting portion of the motorcycle 1, by connecting a tool to the tool connecting portion 72 and rotating each of the adjusting bolts 70, the distance between the adapter 100 and the mounting portion of the motorcycle 1 can be changed at the position of each of the adjusting bolts 70. This allows adjustment of the angle of the adapter 100 with respect to the mounting portion of the motorcycle 1. 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 fig. 2 to 4, when the male screw portion 71 of the adjuster bolt 70 is screwed into the female screw portion 12 from the rear of the base portion 10, the adapter 100 is disposed in front of the mounting portion of the motorcycle 1, and the tool connecting portion 72 of the adjuster 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 angle adjustment from the front of the adapter 100 is an example.

As shown in fig. 8, when the male screw portion 71 of the adjuster bolt 70 is screwed from the front direction female screw portion 12 of the base portion 10, the adapter 100 is disposed rearward of the mounting portion of the motorcycle 1, and the tool connecting portion 72 of the adjuster bolt 70 protrudes rearward 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 of 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, in other words, from both the front and rear sides of the radar device 60. According to the mounting portion of motorcycle 1 and the structure around the mounting portion, there are cases where the installation space of adapter 100 and radar device 60 can be further reduced when adapter 100 is disposed in front of the mounting portion, and cases where the installation space of adapter 100 and radar device 60 can be further reduced when adapter 100 is disposed behind the mounting portion. The adapter 100 of 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, and therefore, the installation space of the adapter 100 and the radar device 60 can be reduced. That is, the installation space of the radar unit 3 can be reduced.

The adapter 100 of the present embodiment includes three female screw portions 12 and three adjusting bolts 70. However, the number of the female screw portions 12 is not limited to three, nor is the number of the adjustment bolts 70 limited to three. If the distance between the adaptor 100 and the mounting portion of the motorcycle 1 can be adjusted at least at three locations, the angle of the adaptor 100 with respect to the mounting portion of the motorcycle 1 can be adjusted. Therefore, the number of the female screw portions 12 may be four or more as long as there are at least three. Likewise, the adjusting bolts 70 may be four or more as long as they are at least three.

In the adapter 100 of the present embodiment, when the adjustment bolts 70 are attached to the female screw portion 12, the adjustment bolts 70 are arranged on the outer peripheral side of the radar device 60. With such a configuration, the angle of the adapter 100 with respect to the mounting portion of the motorcycle 1 can be adjusted in both the state before the radar device 60 is held by the adapter 100 and the state after the radar device 60 is held by the adapter 100. Therefore, the adjustment work of the angle of the adapter 100 with respect to the mounting portion of the motorcycle 1 becomes easy.

In the adapter 100 of the present embodiment, a fixing female screw portion 13 into which a fixing bolt inserted into a through hole of an attachment portion of the motorcycle 1 is screwed is formed. 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 adjustment bolt 70. Therefore, the adapter 100 of the present embodiment can be reduced in size compared to an adapter without the fixing female screw portion 13, without adjusting the angle of the adapter 100 with respect to the mounting portion of the motorcycle 1. In addition, the number of the fixing female screw portions 13 is not particularly limited, and in the present embodiment, three fixing female screw portions 13 are formed.

< holding method of radar apparatus by adapter >

Next, a method of holding the radar device 60 by the adapter 100 will be described.

First, the rear surface 66 of the radar device 60 is brought close 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 a state before the radar device 60 is inserted between the tongue piece 31 of the first support part 20 and the second support part 40, the distance between the tongue piece 31 of the first support part 20 and the second support part 40 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, in a state where 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 shorter than the distance between the first side surface 61 and the second side surface 62 of the radar device 60. 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 pushed in a direction away from the second support portion 40 by the first side surface 61 of the radar device 60.

This elastically deforms the tongue piece 31 between its base portion 32 and the contact portion 34. Further, the base portion 32 of the tongue piece 31 is connected to the coupling 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 connection portion 21 is pushed in a direction away from the second support portion 40 via the tongue piece 31 by the first side surface 61 of the radar device 60. 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 connection 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 is elastically deformed as described above and the reaction force generated when the coupling portion 21 is elastically deformed as described above act on the first side surface 61 of the radar device 60. Thereby, 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 of the present embodiment is a resin adapter that is mounted on a mounting portion of a vehicle and holds the radar device 60. The adapter 100 includes: a base portion 10 that opposes a transmitting/receiving surface 65 or a rear surface 66 of the radar device 60; a first support part 20 connected to the base part 10 and contacting a first side surface 61 of the radar device 60; the second support portion 40 is connected to the base portion 10 and contacts the second side surface 62 of the radar device 60. The adapter 100 is configured to sandwich the radar device 60 between the first support portion 20 and the second support portion 40. The first support portion 20 includes a coupling portion 21 and a tongue piece 31. The connection portion 21 faces the first side surface 61 of the radar device 60, and the

end portions

22 and 23 are connected to the base portion 10. Tongue 31 has base portion 32 connected to coupling portion 21, and extends from base portion 32 in a direction approaching base portion 10. Further, in a state where the radar device 60 is removed from the adapter 100, the tip 33 of the tongue piece 31 becomes a free end. Further, in a state where the radar device 60 is mounted on 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 a conventional resin adapter, a base portion of a tongue piece of a pressing radar device is directly connected to a base portion. In addition, in the conventional resin adapter, the radar device is held by a reaction force generated by elastic deformation between a portion of the tongue piece, which is 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, a load of the tongue piece pushed by the radar device is received between a portion of the tongue piece that contacts the upper surface of the radar device and the base portion. At this time, the distance between the portion of the tongue piece that contacts the radar device and the base is short. Therefore, when the conventional adapter made of resin is used to hold the radar device on the adapter, stress concentration tends to occur in the base portion which is the fixing portion of the tongue piece. Therefore, if the conventional resin adapter is held in the radar device for a while, a creep phenomenon is likely to occur in the base portion of the tongue piece, and the holding force of the radar device is likely to be lowered. If the holding force of the radar device by the adapter is reduced, the radar device is likely to fall off the adapter, for example, when a vehicle on which the adapter and the radar device are mounted vibrates. Further, for example, if the holding force of the radar device by the adapter is reduced, the detection axis of the radar device may be displaced 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 of the present embodiment, not only the tongue piece 31 but also the coupling portion 21 of the first support portion 20 is elastically deformed when the radar device 60 is held. Therefore, the load of tongue piece 31 pushed by radar device 60 is received not only by tongue piece 31 but also by coupling portion 21. That is, the adapter 100 of the present embodiment can receive the load of the tongue piece 31 pushed by the radar device 60 over a longer range than a conventional adapter made of resin. Therefore, in the adapter 100 of the present embodiment, when the radar device 60 is held by the adapter 100, stress concentration can be suppressed from occurring in the base portion 32 that is the fixing portion of the tongue piece 31. Further, the adapter 100 of the present embodiment can suppress stress concentration from occurring at the end portion 22 and the end portion 23 of the coupling portion 21, which are the fixing portions of the first support portion 20, when the radar device 60 is held by the adapter 100. Therefore, the adapter 100 of the present embodiment can suppress the occurrence of the creep phenomenon in the first support portion 20 and suppress the reduction in the holding force of the radar device 60, as compared with the conventional resin adapter. Therefore, the adapter 100 of the present embodiment can suppress the radar device 60 from falling off from the adapter 100, compared to a conventional resin adapter, for example, when a vehicle on which the radar unit 3 of the present embodiment is mounted vibrates. For example, the adapter 100 of the present embodiment can suppress the detection axis misalignment of the radar device 60 when the vehicle on which the radar unit 3 of the present embodiment is mounted vibrates, as compared with a conventional adapter made of resin.

Preferably, in the coupling portion 21, the cross-sectional moment of inertia of the coupling portion side intermediate portion 24 is smaller than the cross-sectional moment of inertia of the end portion connected to the base portion 10. With such a configuration, the coupling portion 21 is more easily elastically deformed uniformly, and stress concentration at the end portion 22 and the end portion 23 of the coupling portion 21 can be more suppressed. That is, with such a configuration, the adapter 100 can further suppress a decrease in the holding force of the radar device 60.

Preferably, in the tongue 31, the moment of area inertia of the tongue-side intermediate portion 35 is smaller than the moment of area inertia of the base portion 32. With such a configuration, tongue piece 31 is more easily and uniformly elastically deformed, and stress concentration in base portion 32 of tongue piece 31 can be more suppressed. In other words, with such a configuration, it is possible to further suppress a decrease in the holding force of the radar device 60 in the adapter 100. Further preferably, the moment of area inertia of the base portion 32 of the tongue piece 31 is smaller than the moment of area inertia of the connecting portion side intermediate portion 24 of the connecting portion 21. With such a configuration, the entire first support section 20 is easily elastically deformed uniformly, and the occurrence of stress concentration in the first support section 20 can be further suppressed. In other words, with such a configuration, the adapter 100 can further suppress a decrease in the holding force of the radar device 60.

Preferably, the vehicle provided with the radar unit 3 of the present embodiment is a motorcycle 1. If the holding force of the radar device 60 in the adapter 100 is reduced, the radar device 60 may loosen in the adapter 100 and generate noise when the vehicle on which the radar unit 3 is mounted moves up and down. Here, in the motorcycle, the driver sits in the cab, and the radar unit 3 is disposed in the engine room or the like. Therefore, in the motorcycle, the driver is less likely to be aware of noise caused by the loosening of the radar device 60 in the adapter 100. On the other hand, the motorcycle 1 does not have a room for the rider to sit in. Therefore, in the motorcycle 1, the driver easily hears noise caused by the loosening of the radar device 60 in the adapter 100. Further, the motorcycle 1 has a shorter wheel base and is easier to move up and down than a motorcycle. In the motorcycle 1, since both the engine and the radar unit 3 are mounted on the frame 2, vibration of the engine is easily transmitted to the radar unit 3. That is, compared to a motorcycle, the motorcycle 1 is more likely to generate noise due to the loosening of the radar device 60 in the adapter 100. Therefore, the radar unit 3 of the present embodiment, which can suppress a reduction in the holding force of the radar device 60, is preferably provided in the motorcycle 1 in which noise due to rattling of the radar device 60 is likely to occur.

< modification example >

Fig. 9 is an assembled perspective view showing a modification of the adapter according to the embodiment of the present invention.

In the above-described adapter 100, the first support portion 20 and the base portion 10 are directly connected. Specifically, the

end portions

22 and 23 of the coupling portion 21 of the first support portion 20 are directly connected to the base portion 10. Not limited to this, the first support portion 20 may be indirectly connected to the base portion 10. That is, the

end portions

22 and 23 of the coupling portion 21 of the first support portion 20 may be indirectly connected to the base portion 10. When the

end portions

22 and 23 of the coupling portion 21 are indirectly connected to the base portion 10, the adapter 100 is specifically configured as shown in fig. 9. In the adaptor 100 shown in fig. 9, the end 22 of the coupling portion 21 is connected to the first side wall 45, and the end 23 of the coupling portion 21 is connected to the second side wall 47. Only one of the

end portions

22 and 23 may be connected to the first side wall 45 or the second side wall 47.

In the adapter 100 in which the first support portion 20 and the base portion 10 are indirectly connected, the load of the tongue piece 31 pushed by the radar device 60 is received not only by the tongue piece 31 but also by the connection portion 21, as in the adapter 100 in which the first support portion 20 and the base portion 10 are directly connected. Therefore, in the adapter 100 in which the first support portion 20 and the base portion 10 are indirectly connected, similarly to the adapter 100 in which the first support portion 20 and the base portion 10 are directly connected, the holding force of the radar device 60 can be suppressed from being lowered as compared with the conventional resin adapter.

Further, the adapter 100 in which the first support portion 20 and the base portion 10 are indirectly connected can obtain the following effects as compared with the adapter 100 in which the first support portion 20 and the base portion 10 are directly connected. In the adapter 100 in which the first support portion 20 and the base portion 10 are indirectly connected, the angle between the edge portion of the coupling portion 21 and the edge portion of the tongue piece 31 can be increased in the connecting portion between the coupling portion 21 and the tongue piece 31, as compared with the adapter 100 in which the first support portion 20 and the base portion 10 are directly connected. Therefore, in the adapter 100 in which the first support portion 20 and the base portion 10 are indirectly connected, stress concentration in the base portion 32, which is a fixing portion of the tongue piece 31, can be more suppressed than in the adapter 100 in which the first support portion 20 and the base portion 10 are directly connected.

On the other hand, the adapter 100 in which the first support portion 20 and the base portion 10 are directly connected can obtain the following effects as compared with the adapter 100 in which the first support portion 20 and the base portion 10 are indirectly connected. When the angle of the adapter 100 with respect to the mounting portion of the motorcycle 1 is adjusted using the adjustment bolt 70, the first side wall 45 and the second side wall 47 may be deformed. In such a case, in the adapter 100 in which the first support portion 20 and the base portion 10 are indirectly connected, the connection portion 21 of the first support portion 20 is connected to the first side wall 45 and the second side wall 47, and therefore the holding force of the radar device 60 may vary due to the deformation of the first side wall 45 and the second side wall 47. In contrast, in the adapter 100 in which the first support portion 20 and the base portion 10 are directly connected to each other, the connection portion 21 of the first support portion 20 is not connected to the first side wall 45 and the second side wall 47. Therefore, the adapter 100 in which the first support portion 20 and the base portion 10 are directly connected can suppress variation in the holding force of the radar device 60 even when the first side wall 45 and the second side wall 47 are deformed.

Similarly to the first support portion 20, the second support portion 40 is not limited to a structure directly connected to the base portion 10. The second support portion 40 may be indirectly connected to the base portion 10, similarly to the first support portion 20.

Fig. 10 is a diagram showing a modification of the radar unit according to the embodiment of the present invention. Fig. 10 is a view showing a modification of the radar unit 3 in the same cross section and observation range as fig. 6.

In the radar unit 3 shown in fig. 10, the first side surface 61 of the radar device 60 is provided with the convex portion 51. The projection 51 projects toward the tongue 31 of the adapter 100. The projection 51 is, for example, a cylindrical pin. On the other hand, tongue piece 31 of adapter 100 has a recess 52 into which protrusion 51 is inserted. Further, the tongue piece 31 of the adapter 100 may be provided with a convex portion 51, and the first side surface 61 of the radar device 60 may be provided with a concave portion 52. That is, in the radar unit 3 shown in fig. 10, the convex portion 51 may be provided on one of the first side surface 61 of the radar device 60 and the tongue piece 31 of the adapter 100, and the concave portion 52 may be formed on the other of the first side surface 61 of the radar device 60 and the tongue piece 31 of the adapter 100.

By configuring the radar unit 3 as shown in fig. 10, the following effects can be obtained in addition to the above-described effects. In the radar unit 3 shown in fig. 10, when the radar device 60 is to be detached from the adapter 100, the convex portion 51 and the concave portion 52 are caught. Therefore, the radar unit 3 shown in fig. 10 can further suppress the radar device 60 from falling off from the adapter 100, compared to the radar unit 3 not provided with the convex portion 51 and the concave portion 52.

Fig. 11 is an assembly perspective view showing another example of a modification of the adapter according to the embodiment of the present invention.

In the above-described adapter 100, the base portion 10, the first support portion 20, and the second support portion 40 are integrally formed. On the other hand, the adapter 100 shown in fig. 11 includes a first member 101 and a second member 102 as members constituting the base portion 10, the first support portion 20, and the second support portion 40. Specifically, the base part 10 includes a first base part 14 to which the first support part 20 is connected, and a second base part 15 to which the second support part 40 is connected. The first base part 14 and the second base part 15 are mutually separated. The first member 101 includes a first base portion 14 and a first support portion 20. The second member 102 includes a second base portion 15 and a second support portion 40. That is, the first member 101 and the second member 102 are mutually separated. In addition, the structure of connecting the first member 101 and the second member 102 is not particularly limited. In the present embodiment, the first member 101 and the second member 102 are connected by screwing and fixing the first member 101 and the second member 102 with the male screw 103.

The base portion 10, the first support portion 20, and the second support portion 40 are formed of the first member 101 and the second member 102 which are separated from each other, and thus the following effects can be obtained. When the base portion 10, the first support portion 20, and the second support portion 40 are formed of the first member 101 and the second member 102 that are separated from each other, the radar device 60 is held by sandwiching the radar device 60 between the first member 101 and the second member 102. Therefore, when the adapter 100 is prepared for a plurality of radar devices 60 having different lengths in the facing direction of the first member 101 and the second member 102, at least one of the first member 101 and the second member 102 can be made common. On the other hand, when the base portion 10, the first support portion 20, and the second support portion 40 are integrally formed, the radar device 60 can be held by the adapter 100 only by inserting the radar device 60 between the first support portion 20 and the second support portion 40. Therefore, when the base portion 10, the first support portion 20, and the second support portion 40 are integrally formed, the attachment process of the radar device 60 to the adapter 100 can be suppressed.

Although the adapter 100 of the present embodiment has been described above, the adapter of the present invention is not limited to the description of the present embodiment, and only a part of the present embodiment may be implemented.
