That is, fig. 2 is a perspective view showing a state where the radar apparatus is held by the adapter according to the embodiment of the present invention. Fig. 3 is an exploded perspective view of an adapter according to an embodiment of the present invention. Fig. 4 is a perspective view showing a radar device according to an embodiment of the present invention.
The adapter 100 of the present embodiment constitutes a radar unit 3 mounted on the straddle-type vehicle 1 together with a radar device 200. In other words, the adapter 100 holds the radar device 200 mounted on the straddle-type vehicle 1.
In the following description of the adapter 100, the portions of the radar apparatus 200 having a substantially rectangular parallelepiped shape are defined as follows. The transmitting/receiving surface 201 is a front surface, and a surface facing the transmitting/receiving surface 201 is a back surface 202. Of the side surfaces of the continuous hair receiving surface 201 and the back surface 202, the side surface serving as the lower surface in the present embodiment is referred to as a lower surface 203. Of the side surfaces that continuously receive the hair side 201 and the back side 202, the side surface facing the lower surface 203 is defined as an upper surface 204. Of the side surfaces of the continuous transmission surface 201 and the back surface 202, the side surface that is the left side surface in the present embodiment is the left side surface 205. The left side surface 205 can also be said to be one of side surfaces connecting the transmission/reception surface 201 and the rear surface 202 and connecting the lower surface 203 and the upper surface 204. Of the side surfaces that continuously receive the hair side 201 and the back side 202, the side surface facing the left side surface 205 is defined as a right side surface 206.
Here, in the present embodiment, the lower surface portion 203 corresponds to the 1 st side surface portion of the present invention, and the upper surface portion 204 corresponds to the 2 nd side surface portion of the present invention.
The adapter 100 includes a 1 st component 10 and a 2 nd component 20.
The 1 st component 10 includes a base portion 11 and a wall portion 12 protruding forward from the base portion 11. The base 11 is disposed to face the rear surface 202 of the radar device 200. The wall portion 12 is a wall portion corresponding to the 1 st wall portion of the present invention in the present embodiment. The wall portion 12 faces the lower surface portion 203 of the radar device 200. The wall portion 12 contacts the lower surface portion 203 of the radar device 200, and supports the lower surface portion 203. In the present embodiment, the radar device 200 held by the adapter 100 is provided with a connector 207 on the lower surface 203, the connector being used when wired to a control device, not shown. Therefore, the escape portion 16 is formed in the wall portion 12 so that the wall portion 12 and the connector 207 do not interfere with each other. The escape portion 16 is a through hole or a notch. That is, when the radar device 200 is held by the adapter 100, the connector 207 is inserted into the escape portion 16.
The component 1 of the present embodiment includes a wall portion 13 and a wall portion 14 protruding forward from the base portion 11. The wall portion 13 is disposed to face the left side surface 205 of the radar device 200. The wall portion 14 is disposed to face the right side surface portion 206 of the radar device 200. That is, in the present embodiment, the wall portion 13 and the wall portion 14 face each other in the lateral direction. As described later, the adapter 100 holds the radar device 200 by vertically sandwiching the radar device 200 between the 1 st part 10 and the 2 nd part 20. At this time, the adapter 100 can hold the radar apparatus 200 with a holding force sufficient to restrict the radar apparatus 200 from moving in the lateral direction. However, by providing the wall portion 13 and the wall portion 14, the radar device 200 can be further restricted from moving in the lateral direction, and the radar device 200 can be further prevented from being detached from the adapter 100.
The 2 nd component 20 includes a base 21 and a wall 22 projecting forward from the base 21. The base 21 is disposed opposite to the 1 st component 10. In the present embodiment, the base 21 does not face the rear surface of the radar device 200, but the base 21 may extend downward and a part of the base 21 may be disposed so as to face the rear surface of the radar device 200. The wall portion 22 is a wall portion corresponding to the 2 nd wall portion of the present invention in the present embodiment. The wall portion 22 faces the upper surface portion 204 of the radar device 200. The wall portion 22 directly or indirectly contacts the upper surface portion 204 of the radar device 200, and supports the upper surface portion 204.
The adapter 100 includes a fastening portion 30. The 1 st component 10 and the 2 nd component 20 are fastened and connected by the fastening and connecting portion 30. In the present embodiment, the fastening portion 30 is formed by a screw fastening structure. Specifically, the fastening portion 30 is constituted by a female screw portion 31 provided in the 1 st component 10, a portion of the 2 nd component 20 where the through hole 32 is formed, and a male screw 33. The female screw portion 31 is disposed at a position facing the 2 nd component 20, for example, at the base portion 11 of the 1 st component 10. The through hole 32 is disposed at a position facing the female screw portion 31, for example, at the base portion 21 of the 2 nd component 20. Then, the male screw 33 is inserted into the through hole 32 of the 2 nd component 20, and the male screw 33 is screwed into the female screw portion 31 of the 1 st component 10, whereby the 2 nd component 20 is fastened and coupled to the 1 st component 10. When the 2 nd component 20 is fastened and coupled to the 1 st component 10, the radar device 200 is sandwiched between the wall portion 12 of the 1 st component 10 and the wall portion 22 of the 2 nd component 20. Accordingly, the fastening force of the fastening portion 30 acting in the vertical direction becomes a holding force, and the radar device 200 is held by the adapter 100.
In the adapter 100 of the present embodiment, two fastening portions 30 are provided, but the number of fastening portions 30 is not particularly limited. The fastening portion 30 is not limited to a member having a screw fastening structure. Conventionally, a snap fastener structure is known as a structure for fastening and connecting two components. For example, the fastening connection 30 may also be constructed using snap fasteners.
However, the adapter 100 according to the present embodiment can hold a plurality of radar devices 200 having different positions of the connector 207 by the same adapter 100. Specifically, the adapter 100 has a relief portion 16 formed on the wall portion 13 and the wall portion 14 in addition to the wall portion 12. Therefore, by inserting the connector 207 into the escape portion 16 of the wall portion 13, the adapter 100 can be held by the radar apparatus 200 in which the connector 207 is provided on the left side surface portion 205. Further, by inserting the connector 207 into the escape portion 16 of the wall portion 14, the adapter 100 can be held in the radar apparatus 200 in which the connector 207 is provided on the right side surface portion 206.
The adapter 100 of the present embodiment is provided with an adjustment mechanism for adjusting the angle of the detection axis of the radar device 200 with respect to the attachment portion of the straddle-type vehicle 1. Specifically, the adapter 100 includes three female screw portions 15 and 3 adjusting bolts 70 as the adjusting mechanism. Each of the female screw portions 15 is formed in the 1 st component 10 so as to penetrate in the front-rear direction, for example. Each of the adjustment bolts 70 has an external thread portion 71 that engages with the internal thread portion 15. Further, a tool coupling portion 72 having a polygonal cross-sectional shape, for example, is provided at an end of the external thread portion 71. That is, the adjusting bolt 70 can be moved relative to the 1 st component 10 in the penetrating direction of the female screw portion 15 by screwing the male screw portion 71 of the adjusting bolt 70 into the female screw portion 15 of the 1 st component 10, connecting the tool to the tool connecting portion 72, and turning the adjusting bolt 70.
Further, one end of the adjusting bolt 70, which is an end portion on the opposite side from the tool connecting portion 72, is rotatably and angularly movably attached to the mounting portion of the straddle-type vehicle 1. The mounting structure of the one end of the adjusting bolt 70 and the mounting portion of the straddle-type vehicle 1 is not particularly limited as long as the adjusting bolt 70 is rotatable and angularly variable with respect to the mounting portion of the straddle-type vehicle 1. Universal joints of various structures in which two connecting parts are connected to each other so as to be rotatable and changeable in angle are known. For example, one end of the adjusting bolt 70 may be rotatably and angularly movably attached to the attachment portion of the straddle-type vehicle 1 by a known coupling structure of such a universal joint.
In the present embodiment, one end of the adjusting bolt 70 is rotatably and angularly movably attached to an attachment portion of the straddle-type vehicle 1 by an attachment component 80 that constitutes a universal joint together with the adjusting bolt 70. The mounting component 80 may be an accessory of the adapter 100, or may be an accessory of the straddle-type vehicle 1. Specifically, a ball head 73 having a partially spherical outer peripheral portion is formed at an end portion of the adjusting bolt 70 on the opposite side to the tool connecting portion 72. The mounting component 80 further includes a holding portion 81 for rotatably and angularly movably holding the ball portion 73 of the adjusting bolt 70. The structure of the holding portion 81 for holding the ball portion 73 is not particularly limited. As the structure for holding the ball head portion 73 by the holding portion 81, various known structures for rotatably holding the ball head portion and for variably changing the angle in a universal joint can be used.
The adapter 100 is attached to the mounting portion of the straddle-type vehicle 1 by screwing the external thread portion 71 of the adjuster bolt 70 into each of the internal thread portions 15 of the 1 st component 10, mounting the same number of mounting components 80 as the adjuster bolt 70 on the mounting portion of the straddle-type vehicle 1, and causing the retaining portions 81 of the mounting components 80 to retain the ball portions 73 of the adjuster bolts 70. In a state where the adapter 100 is mounted on the mounting portion of the straddle-type vehicle 1, the distance between the adapter 100 and the mounting portion of the straddle-type vehicle 1 can be changed at the position of each adjustment bolt 70 by connecting a tool to the tool connection portion 72 and rotating each adjustment bolt 70. This allows adjustment of the angle of the adapter 100 with respect to the mounting portion of the straddle-type vehicle 1. That is, the angle of the detection axis of the radar device 200 held by the adapter 100 can be adjusted with respect to the mounting portion of the straddle-type vehicle 1.
In addition, a method of adjusting the angle from the front of the adapter 100 is an example. When the male screw portion 71 of the adjuster bolt 70 is screwed into the female screw portion 15 from the front of the 1 st component 10, the adapter 100 is disposed behind the mounting portion of the straddle-type vehicle 1, and the tool connecting portion 72 of the adjuster bolt 70 protrudes rearward of the 1 st component 10. Therefore, the angle of the adapter 100 with respect to the mounting portion of the straddle-type vehicle 1 can be adjusted from the rear of the adapter 100.
The adapter 100 of the present embodiment includes three female screw portions 15 and 3 adjusting bolts 70. However, the number of the female screw portions 15 is not limited to 3, nor is the number of the adjusting bolts 70 limited to 3. The angle of the adapter 100 with respect to the mounting portion of the straddle-type vehicle 1 can be adjusted as long as the distance between the adapter 100 and the mounting portion of the straddle-type vehicle 1 can be adjusted at least 3 locations. Therefore, the number of the female screw portions 15 may be at least 3, and may be 4 or more. Similarly, the number of the adjustment bolts 70 may be at least 3, and may be at least 4. In the adapter 100 of the present embodiment, all the female screw portions 15 are provided in the 1 st component 10. Without being limited to this, at least a part of the female screw portion 15 may be provided in the No. 2 element 20.
Here, as shown in fig. 2, when the radar device 200 is held by the adapter 100, the end 23 of the 2 nd component 20 on the side of the transmission/reception surface 201 is located at a position separated from the transmission/reception surface 201 from the rear surface 202 with respect to the rear surface 202 in the direction of the transmission/reception surface 201 and the rear surface 202. In other words, in the case of the present embodiment, when the radar device 200 is held by the adapter 100, the end 23 of the 2 nd component 20 on the side of the transmission/reception surface 201 protrudes forward of the radar device 200 in the direction in which the transmission/reception surface 201 and the back surface 202 face each other. When the radar device 200 is held by the adapter 100, the end 23 of the 2 nd component 20 on the side of the transmission/reception surface 201 may be located at the same position as the transmission/reception surface 201 in the direction in which the transmission/reception surface 201 and the back surface 202 face each other. In the present embodiment, when the radar device 200 is held by the adapter 100, the end 24 of the 2 nd component 20 on the back surface 202 side is located at the same position as the back surface 202 or is located away from the transmission/reception surface 201 with respect to the transmission/reception surface 201 as compared to the back surface 202 in the direction in which the transmission/reception surface 201 and the back surface 202 face each other.
In the radar device 200, parts corroded by water, such as metal parts, may be exposed to the outside. When the radar device 200 is held by the adapter 100, the end 23 of the 2 nd component 20 on the transmitting/receiving surface 201 side is arranged at the above-described position, and thereby the upper side of the radar device 200 can be covered with the 2 nd component 20. Therefore, it is possible to suppress adhesion of water such as rainwater to the parts of the radar device 200, which may be corroded by the water, and to suppress corrosion of the parts. In addition, the 2 nd component 20 does not need to cover the entire upper side of the radar device 200 in the facing direction of the wall portion 13 and the wall portion 14. For example, a portion of the radar device 200 that is not corroded by water may be covered with no component 2 20 in the facing direction of the wall portion 13 and the wall portion 14.
Fig. 5 is a vertical cross-sectional view of an upper portion of another example of the radar unit according to the embodiment of the present invention, as viewed from the side.
When the radar device 200 is held by the adapter 100, the end 23 of the 2 nd component 20 on the side of the transmission/reception surface 201 is located at a position separated from the transmission/reception surface 201 from the rear surface 202 with respect to the rear surface 202 in the direction in which the transmission/reception surface 201 and the rear surface 202 face each other. In this case, the end 23 of the 2 nd component 20 on the transmitting/receiving surface 201 side may be curved toward the wall 12, in other words, toward the radar device 200. This can prevent water from entering between the part 2 20 and the upper surface portion 204 of the radar device 200 from the end 23 side of the part 2 20. In other words, in the case of the present embodiment, water can be prevented from entering between the 2 nd component 20 and the upper surface portion 204 of the radar device 200 from the front of the radar unit 3. Therefore, it is possible to further suppress adhesion of water such as rainwater to the parts of the radar device 200, which may be corroded by the water, and to further suppress corrosion of the parts. Reference numeral 40 shown in fig. 5 denotes a radar positioning unit 40 described later.
The adapter 100 further includes a positioning structure for positioning the radar device 200 with respect to the adapter 100. Specifically, the adapter 100 includes a positioning structure for positioning the side portion of the wall portion 12 of the radar device 200 and a positioning structure for positioning the side portion of the wall portion 22 of the radar device 200. In other words, in the case of the present embodiment, the adapter 100 includes a positioning structure for positioning a lower portion of the radar device 200 and a positioning structure for positioning an upper portion of the radar device 200. The following describes details of these positioning structures.
The adapter 100 includes a groove 60 as a positioning structure for positioning a portion of the wall 12 of the radar device 200 with respect to the adapter 100, in each of the wall 13 and the wall 14 of the 1 st component 10. The protruding portion 209 of the radar device 200 is inserted into the groove portion 60. Thereby, the wall portion 12 side portion of the radar device 200 is positioned to the adapter 100. Specifically, the protrusion 209 provided on the left side surface 205 of the adapter 100 is inserted into the groove 60 of the wall 13. The protrusion 209 provided on the right side surface 206 of the adapter 100 is inserted into the groove 60 of the wall 14. The projection 209 is, for example, a pin attached to an outer contour portion of the radar device 200. The protrusion 209 may be formed integrally with the outer shell of the radar device 200. In the present embodiment, the protrusion 209 has a cylindrical shape, but the protrusion 209 may have a shape other than a cylindrical shape. The groove portion 60 opens to the 2 nd part 20. In the present embodiment, the groove 60 extends in the direction in which the 1 st component 10 and the 2 nd component 20 face each other. However, if the groove portion 60 opens to the 2 nd component 20, the direction in which the groove portion 60 extends may be inclined with respect to the facing direction of the 1 st component 10 and the 2 nd component 20.
The conventional adapter holding the radar device is an integral component. That is, the conventional adapter for holding a radar device is configured such that the 1 st part 10 and the 2 nd part 20 of the adapter 100 are integrally formed. Therefore, when the conventional adapter is provided with the same groove as the groove 60 of the present embodiment and attempts to position the radar device with respect to the adapter, the adapter is caused to hold the radar device as described below. First, a portion where the protruding portion of the radar device is provided is inserted into the adapter from the opening of the adapter. Then, the protruding portion of the radar device is inserted into the groove portion of the adapter. Then, the radar device is rotated around the protruding portion of the radar device as a rotation center, and the radar device is pushed into the adapter from the opening of the adapter. Thereby, the radar apparatus is held by the adapter. As described above, in the case where the conventional adapter is provided with the same groove portion as the groove portion 60 of the present embodiment, when the adapter holds the radar device, the step of pushing in while rotating the radar as described above is required, and therefore, the work of holding the radar device becomes complicated.
On the other hand, in the adapter 100 of the present embodiment, the projection 209 provided in the radar device 200 can be inserted into the groove 60 provided in the 1 st component 10 by inserting the radar device 200 into the 1 st component 10 in the direction in which the 1 st component 10 and the 2 nd component 20 face each other. Then, in the adapter 100 of the present embodiment, the 1 st component 10 and the 2 nd component 20 are fastened and connected by the fastening and connecting portion 30, whereby the adapter 100 can hold the radar device 200. Therefore, the adapter 100 according to the present embodiment does not require the above-described step of rotating the radar device and pushing it into the adapter when the adapter 200 holds the radar device 100. Therefore, the adapter 100 according to the present embodiment can position the radar device 200 in the adapter 100, and the operation of holding the radar device 200 by the adapter 100 is facilitated.
The projection 209 may be provided in the 1 st component 10, and the groove 60 may be provided in the radar device 200. In this case, specifically, the wall 13 and the wall 14 of the 1 st component 10 are provided with the protruding portions 209. The groove portions 60 are provided in the left side surface 205 and the right side surface 206 of the radar device 200. The groove portions 60 provided in the left side surface portion 205 and the right side surface portion 206 of the radar device 200 are open to the lower surface portion 203 of the radar device 200.
When the adapter 100 and the radar device 200 are configured in this way, that is, when the radar unit 3 is configured in this way, the projection 209 can be inserted into the groove 60 by inserting the radar device 200 into the 1 st component 10 in the direction in which the 1 st component 10 and the 2 nd component 20 face each other. Then, the 1 st component 10 and the 2 nd component 20 are fastened and coupled by the fastening and coupling portion 30, whereby the adapter 100 can hold the radar device 200. Further, when the adapter 100 holds the radar device 200, the above-described step of rotating the radar device and pushing in the adapter is not necessary. Therefore, even when the radar unit 3 is configured in this manner, the radar device 200 can be positioned in the adapter 100, and the operation of holding the radar device 200 by the adapter 100 is facilitated.
In the present embodiment, the groove portion 60 is configured as follows.
Fig. 6 and 7 are enlarged views of essential parts of the periphery of the groove of the adapter according to the embodiment of the present invention. Fig. 6 and 7 are views of the groove 60 provided in the wall 13 of the 1 st part 10 of the adapter 100, as viewed in the direction of the arrow a shown in fig. 3. Fig. 6 shows the groove 60 before the protrusion 209 of the radar device 200 is inserted. Fig. 7 shows the groove 60 in a state where the protrusion 209 of the radar device 200 is inserted. In addition, the groove 60 provided at the wall portion 14 of the 1 st part 10 of the adapter 100 is identical in structure to the groove 60 provided at the wall portion 13 of the 1 st part 10 of the adapter 100.
The 1 st end 61 of the groove 60 is open. The projection 209 of the radar device 200 inserted from the 1 st end 61 abuts against the 2 nd end 62, whereby the radar device 200 is positioned. The groove 60 includes a narrowed portion 63 at a position between the 1 st end 61 and the 2 nd end 62. The reduced portion 63 is a portion having a reduced width in a direction perpendicular to a direction connecting the 1 st end portion 61 and the 2 nd end portion 62. Specifically, the groove 60 includes a side wall 64 and a side wall 65 as side walls connecting the 1 st end 61 and the 2 nd end 62. The groove portion 60 includes a convex portion 66 protruding inward of the groove portion 60 at each of the side wall portions 64 and 65. In the present embodiment, these projections 66 are the reduced portions 63. In the present embodiment, the side wall portions 64 and 65 have a substantially L-shaped shape (or a substantially v-shaped shape of 1236767. However, this shape of the side wall portion 64 and the side wall portion 65 is an example. For example, the side wall portion 64 and the side wall portion 65 may have a substantially linear shape.
The groove 60 is narrowed at a narrowed portion 63 in a width in a direction perpendicular to a direction connecting the 1 st end portion 61 and the 2 nd end portion 62. In fig. 6 and 7, the width of the groove 60 in the lateral direction is reduced at the reduced portion 63. In a state before the protrusion 209 of the radar device 200 is inserted into the groove 60, the width of the reduced portion 63 is smaller than the width of the protrusion 209 of the radar device 200 in a direction perpendicular to a direction connecting the 1 st end portion 61 and the 2 nd end portion 62. Therefore, when the protrusion 209 of the radar device 200 is inserted into the groove 60, the reduced portion 63 is pressed by the protrusion 209 of the radar device 200 and is plastically deformed. That is, in a state where the projection 209 of the radar device 200 abuts on the 2 nd end portion 62 and the radar device 200 is positioned, the groove portion 60 and the projection 209 of the radar device 200 inserted into the groove portion 60 come into surface contact with each other at a portion of the reduced portion 63 that is plastically deformed by the projection 209 of the radar device 200.
When the contact area between the groove 60 and the projection 209 of the radar device 200 inserted into the groove 60 is small, the contact portion between the groove 60 and the projection 209 of the radar device 200 is easily worn by the vibration transmitted to the radar device 200 and the adapter 100. Therefore, when the contact area between the groove 60 and the projection 209 of the radar device 200 inserted into the groove 60 is small, the radar device 200 held by the adapter 100 is likely to shake. However, in the adapter 100 of the present embodiment, when the radar device 200 is held, the contact area between the groove portion 60 and the protrusion 209 of the radar device 200 inserted into the groove portion 60 can be increased. Therefore, the adapter 100 of the present embodiment can position the radar device 200, and can suppress the fluctuation of the radar device 200.
Here, it is preferable that the convex portion 66 provided on each of the side wall portion 64 and the side wall portion 65 is equidistant from the 2 nd end portion 62 in the direction connecting the 1 st end portion 61 and the 2 nd end portion 62. In other words, in fig. 6 and 7, the direction connecting the 1 st end 61 and the 2 nd end 62 is the vertical direction. In this case, it is preferable that the convex portion 66 provided on the side wall portion 64 and the convex portion 66 provided on the side wall portion 65 have the same height. By disposing the protruding portions 66 provided on the side wall portions 64 and 65 in this manner, when the protruding portions 209 of the radar device 200 are inserted into the groove portions 60, the two protruding portions 66 are simultaneously pressed, and the two protruding portions 66 are simultaneously plastically deformed. Therefore, by disposing the convex portion 66 provided on each of the side wall portion 64 and the side wall portion 65 in this manner, the positioning accuracy of the radar device 200 is improved. When the distance from the 2 nd end 62 is measured in the direction connecting the 1 st end 61 and the 2 nd end 62, for example, the portion of the 2 nd end 62 most distant from the 1 st end 61 is measured as the measurement position of the 2 nd end 62. For example, in the case of fig. 6 and 7, the lowermost portion of the 2 nd end portion 62 is the measurement position of the 2 nd end portion 62.
In the present embodiment, the protruding portion 209 of the radar device 200 has a cylindrical shape. In this case, the 2 nd end 62 of the groove 60 is preferably formed in an arc shape recessed in a direction away from the 1 st end 61. By configuring the 2 nd end portion 62 of the groove portion 60 in this manner, the contact area between the 2 nd end portion 62 of the groove portion 60 and the protruding portion 209 of the radar device 200 is increased as compared with the case where the 2 nd end portion 62 has a V-shaped shape. Therefore, by configuring the 2 nd end portion 62 of the groove portion 60 in this manner, the rattling of the radar device 200 in the adapter 100 can be further suppressed.
Further, when the projection 209 of the radar device 200 has a cylindrical shape and the 2 nd end 62 of the groove 60 has an arc shape recessed in a direction away from the 1 st end 61, a portion of the reduced portion 63 which comes into contact with the projection 209 of the radar device 200 is preferably located at the same position as the center axis of the projection 209 in the direction connecting the 1 st end 61 and the 2 nd end 62, or is preferably located closer to the 2 nd end 62 than the center axis of the projection 209. In other words, in fig. 6 and 7 in which the direction connecting the 1 st end portion 61 and the 2 nd end portion 62 is the vertical direction, the portion of the reduced portion 63 that contacts the projection 209 of the radar device 200 is preferably lower than the central axis of the projection 209. When the protruding portion 209 of the radar device 200 has a cylindrical shape, the width of the protruding portion 209 at the position of the central axis is the widest in the direction perpendicular to the direction connecting the 1 st end portion 61 and the 2 nd end portion 62. Therefore, by configuring the reduced portion 63 in this manner, the portion of the protruding portion 209 having the widest width in the direction perpendicular to the direction connecting the 1 st end portion 61 and the 2 nd end portion 62 passes before the reduced portion 63, and the protruding portion 209 comes into contact with the 2 nd end portion 62. Therefore, by configuring the reduced portion 63 in this way, it is possible to further suppress the occurrence of rattling between the protruding portion 209 and the reduced portion 63, and to further suppress rattling of the radar device 200 in the adapter 100.
The configuration of the reduced portion 63 can be realized as follows, for example. As shown in fig. 6, in one of the side wall portion 64 and the side wall portion 65 connecting the 1 st end portion 61 and the 2 nd end portion 62, an end portion of the narrowed portion 63 on the 2 nd end portion 62 side, which is a portion contacting the protruding portion 209 of the radar device 200, is defined as a 1 st point P1. The other of the side wall portion 64 and the side wall portion 65 connecting the 1 st end portion 61 and the 2 nd end portion 62 has a 2 nd point P2 at the end portion on the 2 nd end portion 62 side of the portion of the reduced portion 63 in contact with the projection 209 of the radar device 200. The center point of the 2 nd end 62 having the circular arc shape is set as a center point C. A virtual straight line connecting the center point C and the 1 st point P1 is defined as a 1 st virtual straight line L1. A virtual straight line connecting the center point C and the 2 nd point P2 is defined as a 2 nd virtual straight line L2.
When defined in this way, the angle α formed by the 1 st virtual straight line L1 and the 2 nd virtual straight line L2 on the 2 nd end 62 side may be 180 ° or less. When the contact area between the 2 nd end portion 62 and the projection 209 is to be increased, the radius of the circular arc shape of the 2 nd end portion 62 is substantially the same as the radius of the outer peripheral portion of the projection 209. Therefore, the center point C is substantially the same position as the center axis of the protrusion 209. Therefore, by setting the angle α to 180 ° or less, the portion of the reduced portion 63 that contacts the projection 209 of the radar device 200 is located at the same position as the center axis of the projection 209 in the direction connecting the 1 st end portion 61 and the 2 nd end portion 62, or is located closer to the 2 nd end portion 62 than the center axis of the projection 209.
Further, it is preferable that the 1 st end 61 of the groove portion 60 becomes wider as it goes away from the 2 nd end 62. In the present embodiment, the 1 st end portion 61 of the groove portion 60 is widened as it goes away from the 2 nd end portion 62 by the inclined surface 67 formed at the 1 st end portion 61. The 1 st end 61 of the groove 60 is widened as it is separated from the 2 nd end 62, so that the insertion of the projection 209 into the groove 60 is facilitated, and the adapter 100 can easily hold the radar device 200.
The reduced portion 63 is not limited to the projection 66. An example of the groove portion 60 including the reduced portion 63 other than the convex portion 66 will be described below.
Fig. 8 is an enlarged partial view showing a periphery of a groove portion of another example of the adapter according to the embodiment of the present invention.
In the groove portion 60 shown in fig. 8, the side wall portion 64 and the side wall portion 65 approach from the 2 nd end portion 62 toward the 1 st end portion 61. Even if the groove 60 is formed in this way, the narrowed portion 63 is formed at a position between the 1 st end portion 61 and the 2 nd end portion 62. When the protrusion 209 of the radar device 200 is inserted into the groove 60, the reduced portion 63 is pressed by the protrusion 209 of the radar device 200 and is plastically deformed.
Fig. 9 is a longitudinal sectional view of the radar unit according to the embodiment of the present invention as viewed from the front.
The adapter 100 includes the radar positioning portion 40 and the adapter positioning portion 50 as a positioning structure for positioning the wall portion 22 side portion of the radar device 200 with respect to the adapter 100. The radar positioning portion 40 is provided in the 2 nd part 20 of the adapter 100, and positions the radar device 200 with respect to the 2 nd part 20. The adapter positioning portion 50 has a 1 st positioning portion provided to the 1 st part 10 of the adapter 100 and a 2 nd positioning portion provided to the 2 nd part 20 of the adapter 100, and positions the 1 st part 10 and the 2 nd part 20. That is, by positioning the radar device 200 with respect to the 2 nd part 20 by the radar positioning portion 40, and positioning the 1 st part 10 and the 2 nd part 20 by the adapter positioning portion 50, the wall portion 22-side portion of the radar device 200 is positioned with respect to the adapter 100.
The conventional adapter is an integral member and is configured to hold a radar device pushed into the adapter from an opening. When the conventional adapter having such a configuration holds the radar device by the adapter, the position of the radar device relative to the adapter is greatly displaced.
On the other hand, in the adapter 100 of the present embodiment, the radar device 200 can be positioned with respect to the adapter 100 by positioning the radar device 200 with respect to the 2 nd part 20 by the radar positioning portion 40, and by positioning the 1 st part 10 and the 2 nd part 20 by the adapter positioning portion 50. Therefore, the adapter 100 of the present embodiment can suppress the displacement of the radar device 200 from the adapter 100 when the radar device 200 is held by the adapter 100, compared to the conventional case.
In the present embodiment, the adapter positioning portion 50 includes a recess 51 as a 1 st positioning portion provided in the 1 st part 10, and a protrusion 52 as a 2 nd positioning portion provided in the 2 nd part 20. The protruding portion 52 has, for example, a cylindrical shape and is inserted into the recessed portion 51. That is, the adapter positioning portion 50 of the present embodiment positions the 1 st part 10 and the 2 nd part 20 by inserting the protruding portion 52 into the recessed portion 51. The protruding portion 52 may be formed integrally with the base portion 11 of the 1 st component 10 or the like, or may be attached to the base portion 11 or the like via a pin or the like formed separately from the base portion 11 or the like. In the present embodiment, the protruding portion 52 has a cylindrical shape, but the protruding portion 209 may have a shape other than a cylindrical shape. In the present embodiment, the inclined surface 53 is formed in the opening of the concave portion 51 so as to increase toward the protruding portion 52. This facilitates insertion of the protrusion 52 into the recess 51, and positioning of the 1 st and 2 nd parts 10 and 20. In the present embodiment, two adapter positioning portions 50 configured as described above are provided in the adapter 100. In other words, in the present embodiment, the pair of adapter positioning portions 50 configured as described above is provided at the adapter 100.
The above-described configuration of the adapter positioning portion 50 is an example. For example, the adapter positioning portion 50 may include a projection 52 as a 1 st positioning portion provided in the 1 st part 10 and a recess 51 as a 2 nd positioning portion provided in the 2 nd part 20. For example, the adapter positioning portion 50 may be configured to position the stepped portions in contact with each other, or may be configured to use a configuration other than the recessed portion 51 and the protruding portion 52. In addition, the number of the adapter positioning portions 50 is also arbitrary as long as the rotation of the 2 nd part 20 with respect to the 1 st part 10 can be regulated by the adapter positioning portions 50.
In the present embodiment, the radar positioning portion 40 includes the concave portion 41. The protruding portion 208 provided at the upper surface portion 204 of the radar device 200 is inserted into the recessed portion 41. Thereby, the radar apparatus 200 is positioned relative to the 2 nd part 20. The protrusion 208 is, for example, a pin attached to the outer contour of the radar device 200. The protrusion 208 may be a member integrally formed with the outer contour of the radar device 200. In the present embodiment, the inclined surface 43 is formed in the opening of the recess 41 so that the opening is larger toward the protrusion 208. This facilitates insertion of the protrusion 208 into the recess 41, and positioning of the radar device 200 and the 2 nd component 20. In the present embodiment, the adapter 100 is provided with the radar positioning section 40 configured as described above.
The above-described adapter positioning portion 50 is an example. For example, in the case where the radar device 200 is provided with a concave portion, the radar positioning portion 40 may be a convex portion inserted into the concave portion. For example, the radar positioning portion 40 may be configured to position the stepped portions by abutting against each other, or may be configured to use a configuration other than the recessed portion and the protruding portion. Further, two or more radar positioning portions 40 may be provided in the adapter 100.
Here, in the present embodiment, the radar positioning portion 40 is configured to press the radar device 200 against the wall portion 12 of the 1 st component 10 in a state where the 1 st component 10 and the 2 nd component 20 are fastened and connected by the fastening and connecting portion 30. Specifically, the radar positioning portion 40 includes a convex portion 42 that protrudes from the wall portion 22 of the 2 nd component 20 toward the wall portion 12 of the 1 st component 10. Further, a concave portion 41 of the radar positioning portion 40 is provided at a distal end portion of the convex portion 42. In a state where the 1 st component 10 and the 2 nd component 20 are fastened and coupled by the fastening and coupling portion 30, the distal end portion of the convex portion 42 of the radar positioning portion 40 presses the radar device 200 against the wall portion 12 of the 1 st component 10.
When the radar device 200 is sandwiched between the wall 12 of the 1 st component 10 and the wall 22 of the 2 nd component 20, the wall 22 of the 2 nd component 20 needs to be provided with a structure for pressing the radar device 200 against the wall 12 of the 1 st component 10. In the present embodiment, this configuration can also be used as the radar positioning section 40. Therefore, the configuration in which the radar positioning section 40 presses the radar device 200 against the wall portion 12 of the 1 st component 10 can simplify the shape of the 1 st component 10.
In the present embodiment, the radar positioning section 40 is disposed between the pair of fastening sections 30. In such a case, as shown in fig. 3, it is preferable that at least one pair of the fastening portions 30 is warped so as to protrude toward the wall portion 12 of the 1 st component 10 in a state where the 2 nd component 20 is not fastened to the 1 st component 10 via the fastening portions 30.
When the radar device 200 is sandwiched between the wall portion 12 of the 1 st part 10 and the wall portion 22 of the 2 nd part 20, the radar device 200 is sandwiched by the reaction force acting on the wall portion 22 of the 2 nd part 20. Specifically, when the 1 st component 10 and the 2 nd component 20 are fastened and coupled by the fastening portion 30, the wall portion 22 of the 2 nd component 20 is pressed and deformed in a direction away from the wall portion 12 of the 1 st component 10 by the radar device 200. Therefore, the wall 22 of the 2 nd component 20 is intended to return to its original shape. At this time, a reaction force in a direction toward the wall portion 12 of the 1 st part 10 is generated at the wall portion 22 of the 2 nd part 20. The radar device 200 is held between the wall 12 of the 1 st part 10 and the wall 22 of the 2 nd part 20 by the reaction force.
Therefore, if the pair of fastening portions 30 are flat in the 2 nd component 20 in a state where the 1 st component 10 is not fastened to the fastening portions 30, the pair of fastening portions 30 of the 2 nd component 20 is warped so as to protrude in a direction away from the wall portion 12 of the 1 st component 10 when the 1 st component 10 and the 2 nd component 20 are fastened to each other by the fastening portions 30. On the other hand, when the pair of fastening portions 30 of the 2 nd component 20 in a state where the 1 st component 10 is not fastened to the 1 st component 20 via the fastening portions 30 is warped so as to protrude toward the wall portion 12 of the 1 st component 10 between the pair of fastening portions 30 in the 2 nd component 20 in a state where the 1 st component 10 is not fastened to the 1 st component 30, the pair of fastening portions 30 of the 2 nd component 20 is nearly flat when the 1 st component 10 is fastened to the 2 nd component 20 via the fastening portions 30, as compared with a case where the pair of fastening portions 30 is flat. Therefore, when the 2 nd component 20 in a state of not being fastened to the 1 st component 10 by the fastening and connecting portion 30 is warped so as to protrude toward the wall portion 12 of the 1 st component 10 between the pair of fastening and connecting portions 30, the appearance of the radar unit 3 is improved. In other words, in the case where the pair of fastening portions 30 are warped so as to protrude toward the wall portion 12 of the 1 st component 10 at the 2 nd component 20 in a state where the fastening portions 30 are not fastened to the 1 st component 10 via the fastening portions 30, the appearance of the adapter 100 holding the radar device 200 is improved.
In the present embodiment, the 2 nd component 20 is made of resin. In this case, it is more preferable that the entire 2 nd component 20 is warped so as to protrude toward the wall portion 12 of the 1 st component 10 in a state where the 1 st component 10 is not fastened to the 2 nd component by the fastening portion 30. This is for the following reason. In the 2 nd component 20 in a state of not being fastened to the 1 st component 10 by the fastening portions 30, only between the pair of fastening portions 30 is warped so as to protrude toward the wall portion 12 of the 1 st component 10. In this case, when the 1 st component 10 and the 2 nd component 20 are fastened by the fastening portion 30 and the 2 nd component 20 is deformed, stress concentration occurs in the 2 nd component 20 at a boundary portion between a portion of the fastening portion 30 where the component is warped and a flat portion adjacent to the portion. When the 2 nd component 20 is made of resin, if a creep phenomenon occurs at the boundary portion due to this stress concentration, the reaction force acting on the wall portion 22 of the 2 nd component 20 decreases. That is, the force with which the radar device 200 is sandwiched is reduced.
On the other hand, if the entire 2 nd component 20 in a state of not being fastened to the 1 st component 10 by the fastening portion 30 is warped so as to protrude toward the wall portion 12 of the 1 st component 10, the reaction force acting on the wall portion 22 of the 2 nd component 20 becomes larger than in a case where a part of the 2 nd component 20 is warped so as to protrude toward the wall portion 12 of the 1 st component 10. Therefore, if the entire part 2 of the component 20, which is not fastened to the 1 st component 10 by the fastening portion 30, is warped so as to protrude toward the wall portion 12 of the 1 st component 10, the reaction force acting on the wall portion 22 of the 2 nd component 20 due to the creep phenomenon is reduced and the reaction force acting on the wall portion 22 of the 2 nd component 20 is also increased, as compared with the case where a part of the part is warped so as to protrude toward the wall portion 12 of the 1 st component 10. Therefore, when the 2 nd component 20 is made of resin, and is not fastened to the 1 st component 10 by the fastening portion 30, if the entire 2 nd component 20 is warped so as to protrude toward the wall portion 12 of the 1 st component 10, the adapter 100 can stably hold the radar device 200 for a long period of time.
In addition, even in the case where at least one pair of the fastening portions 30 is warped so as to protrude toward the wall portion 12 of the 1 st component 10 in the 2 nd component 20 in a state of not being fastened to the 1 st component 10 by the fastening portions 30, the following effects can be achieved. The 1 st part 10 and the 2 nd part 20 are firmly coupled, and when the 2 nd part 20 is pressed by the radar device 200, the part of the 2 nd part 20 that is farther from the contact part with the radar device 200 is less likely to be deformed. Therefore, in the case where at least one pair of the fastening portions 30 is warped so as to protrude toward the wall portion 12 of the 1 st component 10 at the 2 nd component 20 in a state of not being fastened to the 1 st component 10 via the fastening portions 30, when the 1 st component 10 and the 2 nd component 20 are fastened to each other, the end portion 23 of the 2 nd component 20 on the transmitting/receiving surface 201 side is easily bent toward the radar device 200. Therefore, in the case where at least one pair of the fastening portions 30 is warped so as to protrude toward the wall portion 12 of the 1 st part 10 at the 2 nd part 20 in a state of not being fastened to the 1 st part 10 via the fastening portions 30, it is possible to easily suppress the intrusion of water between the 2 nd part 20 and the upper surface portion 204 of the radar device 200, and to easily suppress the corrosion of the parts of the radar device 200, which are corroded by the water.
Further, it is preferable that, when the 1 st part 10 and the 2 nd part 20 are fastened and coupled by the fastening and coupling portion 30, the radar positioning portion 40 comes into contact with the radar device 200 after the concave portion 51 and the convex portion 52 of the adapter positioning portion 50 come into contact. For example, when the radar device 200 and the 2 nd part 20 are positioned by the radar positioning portion 40, the recess 51 and the projection 52 of the adapter positioning portion 50 are not yet in contact. In this case, for example, the 2 nd component 20 is rotatably attached to the radar device 200 due to the structure of the radar positioning portion 40. The work of positioning the 2 nd part 20 and the 1 st part 10 in this state by the adapter positioning portion 50 is complicated.
On the other hand, the 1 st part 10 and the 2 nd part 20 are positioned by the adapter positioning portion 50, and thereafter, the radar device 200 and the 2 nd part 20 are positioned by the radar positioning portion 40. In this case, the 2 nd part 20 and the radar device 200 that do not rotate and move can be positioned by the radar positioning portion 40. Therefore, the radar positioning portion 40 and the radar device 200 come into contact after the recess 51 and the protrusion 52 of the adapter positioning portion 50 come into contact, and thus the positioning work of the radar device 200 and the adapter 100 by the radar positioning portion 40 and the adapter positioning portion 50 becomes easy.
Fig. 10 is a vertical cross-sectional view of an upper portion of the radar unit according to the embodiment of the present invention, as viewed from the side.
Fig. 10 shows a state in which a certain force is applied to the 2 nd component 20 in a state in which the 1 st component 10 and the 2 nd component 20 are fastened and coupled by the fastening and coupling portion 30, and the protrusion 208 of the radar device 200 is disengaged from the recess 41 of the radar positioning portion 40 of the 2 nd component 20. In such a state, the radar device 200 is movable in a direction from the rear surface 202 toward the transmission/reception surface 201 as indicated by white arrows in fig. 10, and may fall off the adapter 100.
Here, the 2 nd component 20 of the adapter 100 of the present embodiment includes the engaging portion 25. The engaging portion 25 engages with the radar device 200 when the radar device 200 moves from the rear surface 202 toward the transmitting/receiving surface 201 in a state where the 1 st component 10 and the 2 nd component 20 are fastened and coupled by the fastening and coupling portion 30. In the present embodiment, when the radar device 200 moves in the direction from the rear surface 202 toward the transmitting/receiving surface 201, the engaging portion 25 is configured to engage with the protruding portion 210 provided on the upper surface portion 204 of the radar device 200. However, the position of the radar device 200 to which the hooking portion 25 is hooked is arbitrary. For example, when the radar device 200 moves in the direction from the back surface 202 toward the transmission/reception surface 201, the engaging portion 25 may engage with the transmission/reception surface 201 of the radar device 200. In this case, the protruding portion 210 does not need to be provided in the radar device 200. Since the adapter 100 of the present embodiment includes the engaging portion 25, even when a certain force acts on the 2 nd component 20 and the protrusion 208 of the radar device 200 is disengaged from the recess 41 of the radar positioning portion 40 of the 2 nd component 20 in a state where the 1 st component 10 and the 2 nd component 20 are fastened and connected by the fastening and connecting portion 30, the radar device 200 can be prevented from falling off the adapter 100.
< method for holding radar device at adapter >
Next, a method of holding the radar device 200 by the adapter 100 will be described.
First, the 1 st component 10 and the 2 nd component 20 are not fastened and connected, and the radar device 200 is inserted into the 1 st component 10. Specifically, when the 1 st component 10 and the 2 nd component 20 are fastened and coupled, the radar device 200 is inserted into the 1 st component 10 in a direction that is a direction in which the 1 st component 10 and the 2 nd component 20 face each other. Then, the protrusion 209 provided in the radar device 200 is inserted into the groove 60 provided in the wall 13 and the wall 14 of the 1 st part 10 of the adapter 100. Then, the projection 209 provided in the radar device 200 is brought into contact with the 2 nd end 62 of the groove 60. This enables the wall portion 12-side portion of the radar device 200 to be positioned with respect to the 1 st part 10 of the adapter 100. At this time, the groove 60 opens in the direction of the 2 nd component 20 when the 1 st component 10 and the 2 nd component 20 are fastened. Therefore, the radar device 200 can be inserted into the 1 st part 10 in a state where the facing directions of the lower surface portion 203 and the upper surface portion 204 of the radar device 200 are substantially parallel to the direction of the facing directions of the 1 st part 10 and the 2 nd part 20 when the 1 st part 10 and the 2 nd part 20 are fastened and coupled.
Thereafter, the 1 st and 2 nd parts 10 and 20 of the adapter 100 are positioned by the adapter positioning portion 50, and the radar device 200 is positioned with respect to the 2 nd part 20 by the radar positioning portion 40. Specifically, when the 1 st part 10 and the 2 nd part 20 are fastened, the 2 nd part 20 is brought close to the 1 st part 10 in a direction which is a facing direction of the 1 st part 10 and the 2 nd part 20. Then, in the adapter positioning portion 50, the protrusion 52 is inserted into the recess 51, and the 1 st part 10 and the 2 nd part 20 of the adapter 100 are positioned. The projection 208 of the radar device 200 is inserted into the recess 41 of the radar positioning portion 40, and the radar device 200 is positioned with respect to the 2 nd component 20. Thereby, the wall portion 22-side portion of the radar device 200 can be positioned with respect to the adapter 100.
Here, as described above, the radar device 200 can be inserted into the 1 st part 10 in a state where the facing directions of the lower surface portion 203 and the upper surface portion 204 of the radar device 200 are substantially parallel to the facing directions of the 1 st part 10 and the 2 nd part 20 when the 1 st part 10 and the 2 nd part 20 are fastened and coupled. Therefore, the radar device 200 inserted into the 1 st part 10 is a position where the protruding portion 208 of the radar device 200 easily enters the recessed portion 41 of the radar positioning portion 40 when the adapter positioning portion 50 positions the 1 st part 10 and the 2 nd part 20 of the adapter 100. Specifically, the recess 41 of the radar positioning portion 40 and the protrusion 208 of the radar device 200 are substantially opposed to each other. Therefore, the adapter 100 of the present embodiment easily positions the wall portion 22-side portion of the radar device 200 with respect to the adapter 100.
Finally, the 1 st and 2 nd parts 10, 20 of the adapter 100 are fastened by means of the fastening connection 30. Thereby, the radar device 200 is held between the 1 st part 10 and the 2 nd part 20, and the radar device 200 is held by the adapter 100.
< Effect of adapter >
The adapter 100 of the present embodiment is an adapter that holds a radar device 200 mounted on a straddle-type vehicle 1. The adapter 100 of the present embodiment includes the 1 st component 10, the 2 nd component 20, the radar positioning portion 40, and the adapter positioning portion 50. The 1 st component 10 has a wall portion 12 facing the lower surface portion 203 of the radar device 200. The 2 nd component 20 has a wall portion 22 facing the upper surface portion 204 of the radar device 200, and is fastened and connected to the 1 st component 10 via the fastening and connecting portion 30. The radar positioning unit 40 is provided in the 2 nd component 20, and positions the radar device 200. The adapter positioning portion 50 has a 1 st positioning portion provided in the 1 st part 10 and a 2 nd positioning portion provided in the 2 nd part 20, and positions the 1 st part and the 2 nd part.
