Description

Technical Field

[0001] The present invention relates to an adapter for holding a radar device. Background Art

[0002] Conventionally, in order to detect obstacles, some vehicles are equipped with radar devices using laser radar or millimeter wave radar, etc. Radar devices are used in, for example, ACC systems (adaptive cruise control systems), Stop & Go systems (congestion tracking systems), and traffic warning systems.

[0003] Such a radar device is held on an adapter and mounted on a mounting portion of a vehicle. In addition, a technical solution has been proposed in which an adapter has an adjustment mechanism for adjusting the angle of the adapter relative to the mounting portion in order to adjust the angle of the detection axis of the radar device relative to the mounting portion of the vehicle (see Patent Document 1).

[0007] Problems to be solved by the invention

[0008] In order to install the adapter and the radar device on the mounting part of the vehicle, it is necessary to ensure the installation space of the adapter and the radar device around the mounting part. The installation space includes the space required for adjusting the angle of the adapter relative to the mounting part in addition to the space occupied by the adapter and the radar device. In addition, depending on the structure of the mounting part of the vehicle and the surrounding of the mounting part, there is a case where the installation space of the adapter and the radar device can be reduced by arranging the adapter in front of the mounting part, and there is a case where the installation space of the adapter and the radar device can be reduced by arranging the adapter in the rear of the mounting part.

[0009] However, conventional adapters are structures that can adjust the angle of the adapter relative to the mounting portion only from the front of the adapter. Therefore, conventional adapters can only be arranged in front of the mounting portion of the vehicle. Therefore, conventional adapters have the problem of increasing the installation space of the adapter and the radar device depending on the mounting portion of the vehicle and the structure around the mounting portion.

[0010] The present invention has been made against the background of the above-mentioned problems, and an object of the present invention is to provide an adapter used when a radar device is mounted on a vehicle, which can reduce the installation space of the adapter and the radar device.

[0011] Means for solving problems

[0012] The adapter involved in the present invention is an adapter that is installed on the mounting part of a vehicle and holds a radar device. It is formed with at least three penetrating female threaded parts and has at least three adjustment bolts. One end of the adjustment bolt is installed on the aforementioned mounting part of the aforementioned vehicle so that it can rotate freely and change its angle freely, and is formed with a male threaded part that meshes with the aforementioned female threaded part.

[0013] Effects of the Invention

[0014] The adapter of the present invention can adjust the angle of the adapter relative to the mounting portion of the vehicle from both the front and rear sides of the adapter by changing the insertion direction of the adjustment bolt into the female thread portion. That is, the adapter of the present invention can be arranged on both the front and rear sides of the mounting portion of the vehicle. Therefore, the adapter of the present invention can reduce the installation space of the adapter and the radar device. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Hereinafter, the adapter according to the present invention will be described with reference to the drawings.

[0023] It should be noted that the structure and operation described below are examples, and the adapter involved in the present invention is not limited to such a structure and operation. In addition, in each figure, the same or similar components or parts may be marked with the same mark or omitted. In addition, the microstructure is appropriately simplified or omitted.

[0024] Implementation

[0025] Hereinafter, the adapter according to the present embodiment will be described.

[0026] <Adapter structure>

[0027] Figure 1 It is an exploded perspective view of the adapter according to the embodiment of the present invention. Figure 2 : is an assembly perspective view of an adapter according to an embodiment of the present invention. Figure 3 This is a perspective view showing a state where a radar device is held by an adapter according to an embodiment of the present invention.

[0028] The adapter 100 involved in this embodiment is an adapter that is installed in the mounting portion of the vehicle and holds the radar device 60. The vehicle is a bicycle, an automatic two-wheeled vehicle, an automatic three-wheeled vehicle, an automatic four-wheeled vehicle, etc., which uses at least one of an engine and an electric motor as a driving source. It should be noted that a bicycle refers to all vehicles that can travel on the road by applying a pedal force to the pedals. That is, bicycles include ordinary bicycles, electric-assisted bicycles, electric bicycles, etc. In addition, an automatic two-wheeled vehicle or an automatic three-wheeled vehicle refers to a so-called motorcycle, and motorcycles include automatic bicycles, scooters, electric scooters, etc. In addition, the mounting portion of the vehicle refers to a bracket, etc., which is provided on the vehicle and is used to mount the adapter 100.

[0029] Here, in describing the adapter 100, the parts of the radar device 60 having a substantially rectangular parallelepiped shape are defined as follows. The transmitting and receiving surface 65 is defined as the front side, and the surface opposite to the transmitting and receiving surface 65 is defined as the back side. Among the side parts connecting the transmitting and receiving surface 65 and the back side, the side part that contacts the first support part 12 of the first component 10 described later is defined as the first side part 61. In the case of the present embodiment, the bottom part of the radar device 60 is defined as the first side part 61. Furthermore, among the side parts connecting the transmitting and receiving surface 65 and the back side, the side part that contacts the second support part 22 of the second component 20 described later is defined as the second side part 62. In the case of the present embodiment, the top part of the radar device 60 is defined as the second side part 62. Furthermore, among the side parts connecting the transmitting and receiving surface 65 and the back side, the remaining side parts other than the first side part 61 and the second side part 62 are defined as the third side part 63 and the fourth side part 64. In the case of the present embodiment, the left side part is defined as the third side part 63, and the right side part is defined as the fourth side part 64.

[0030] The adapter 100 has a first component 10 and a second component 20 .

[0031] The first member 10 includes a base 11 and a first support portion 12 protruding forward from the base 11. The base 11 is disposed opposite to the back surface of the radar device 60. The first support portion 12 contacts the first side surface portion 61 of the radar device 60 and supports the first side surface portion 61. Here, in the present embodiment, the radar device 60 held by the adapter 100 is provided with a connector 66 used when connecting the first side surface portion 61 to a control device (not shown) by wiring. Therefore, a through hole 16 is formed in the first support portion 12 so that the first support portion 12 and the connector 66 do not interfere with each other. That is, when the radar device 60 is held by the adapter 100, the connector 66 is inserted into the through hole 16. It should be noted that a cutout portion may be formed in the first support portion 12 instead of the through hole 16 so that the first support portion 12 and the connector 66 do not interfere with each other.

[0032] In addition, a female thread portion 13 is formed on the first component 10, for example, the base 11, at a position opposite to the second component 20. The female thread portion 13 is a female thread portion into which the male thread member 1 is screwed when the male thread member 1 is used to tighten and fix the second component 20 to the first component 10. The number of the female thread portions 13 is not particularly limited, and at least one female thread portion 13 may be formed at each of the two ends of the base 11.

[0033] In addition, the first component 10 involved in this embodiment has a side wall 14 and a side wall 15 protruding forward from the base 11. The side wall 14 is arranged to face the third side portion 63 of the radar device 60. The side wall 15 is arranged to face the fourth side portion 64 of the radar device 60. That is, in this embodiment, the side wall 14 and the side wall 15 face each other in the lateral direction. As described later, the adapter 100 clamps the radar device 60 in the vertical direction by the first component 10 and the second component 20 to hold the radar device 60. At this time, the adapter 100 can hold the radar device 60 with a holding force sufficient to limit the movement of the radar device 60 in the lateral direction. Therefore, the side wall 14 and the side wall 15 are not essential structures. However, by having the side wall 14 and the side wall 15, the movement of the radar device 60 in the lateral direction can be further limited, and the radar device 60 can be further suppressed from detaching from the adapter 100.

[0034] It should be noted that the distance between the side wall 14 and the side wall 15 may be longer than the distance between the third side surface portion 63 and the fourth side surface portion 64 of the radar device 60. Figure 3 The radar device 60 shown in the figure has a longer length between the third side surface portion 63 and the fourth side surface portion 64 than the radar device 60. That is, the versatility of the adapter 100 is improved. In addition, by not providing the side wall 14 and the side wall 15, the same adapter 100 can also be used to hold the same Figure 3 The radar device 60 shown in the figure is a radar device 60 having a longer length between the third side surface portion 63 and the fourth side surface portion 64. That is, the versatility of the adapter 100 is improved.

[0035] The second component 20 has a base 21 and a second support portion 22 protruding forward from the base 21. The base 21 is arranged opposite to the first component 10. It should be noted that in the present embodiment, the base 21 is not opposite to the back of the radar device 60, but the base 21 may be extended downward and a part of the base 21 may be arranged opposite to the back of the radar device 60. The second support portion 22 contacts the second side surface portion 62 of the radar device 60 and supports the second side surface portion 62. In addition, a through hole 23 for inserting the male screw member 1 is formed on, for example, the base 21 of the second component 20 at a position opposite to the female screw portion 13 of the first component 10. The number of through holes 23 and the number of female screw portions 13 are the same.

[0036] The male screw 1 is inserted into the through hole 23 of the second component 20 and screwed into the female screw portion 13 of the first component 10, thereby tightening and fixing the second component 20 to the first component 10. When the second component 20 is tightened and fixed to the first component 10, the radar device 60 is clamped by the first support portion 12 of the first component 10 and the second support portion 22 of the second component 20. As a result, the tightening force of the screw acting in the up-down direction becomes a holding force, and the radar device 60 is held in the adapter 100.

[0037] It should be noted that the adapter 100 can also hold a plurality of radar devices 60 having connectors 66 at different positions using the same adapter 100 .

[0038] Figure 4 This is a perspective view showing a state where a radar device is held by an adapter according to an embodiment of the present invention.

[0039] Figure 4 The radar device 60 shown in the figure has a connector 66 provided on the third side surface 63. When the radar device 60 is held in this manner, the adapter 100 can be used as long as it does not interfere with the connector 66. Figures 1 to 3 The adapter 100 shown. It should be noted that Figure 4 The adapter 100 shown in the figure is designed to avoid interference with the connector 66 disposed on the third side portion 63. Figure 1 and Figure 2 As shown in FIGS. 1 and 1B , a notch portion 17 is formed in the side wall 14 facing the third side surface portion 63 .

[0040] In addition, the adapter 100 involved in the present embodiment has an adjustment mechanism for adjusting the angle of the detection axis of the radar device 60 relative to the mounting portion of the vehicle. Specifically, the adapter 100 has three female threaded portions 30 and three adjustment bolts 40 as the adjustment mechanism. Each of the female threaded portions 30 is formed on the first component 10 in a manner of penetrating in the front-to-back direction, for example. On each of the adjustment bolts 40, a male threaded portion 41 that meshes with the female threaded portion 30 is formed. In addition, at the end of the male threaded portion 41, a tool connecting portion 42 having a cross-sectional shape of, for example, a polygonal shape is provided. That is, by screwing the male threaded portion 41 of the adjustment bolt 40 into the female threaded portion 30 of the first component 10, connecting a tool to the tool connecting portion 42, and rotating the adjustment bolt 40, the adjustment bolt 40 can be relatively moved relative to the first component 10 in the penetration direction of the female threaded portion 30.

[0041] In addition, one end of the adjusting bolt 40, which is the end on the side opposite to the tool connecting portion 42, is rotatably mounted on the mounting portion of the vehicle and the angle thereof can be freely changed. As long as the adjusting bolt 40 is rotatably mounted on the mounting portion of the vehicle and the angle thereof can be freely changed, the mounting structure of the one end of the adjusting bolt 40 and the mounting portion of the vehicle is not particularly limited. Universal joints of various structures in which two connecting members are rotatably and angularly connected are known. For example, one end of the adjusting bolt 40 can be rotatably mounted on the mounting portion of the vehicle and the angle thereof can be freely changed using a known connection structure of such a universal joint.

[0042] In the present embodiment, a mounting component 50 that forms a universal joint together with the adjustment bolt 40 is used, and one end of the adjustment bolt 40 is mounted on the mounting portion of the vehicle so that it can rotate freely and the angle can be changed freely. The mounting component 50 can be an accessory component of the adapter 100, or it can be an accessory component of the vehicle. In detail, a ball head 43 having a spherical shape as a part of the outer periphery is formed at the end of the adjustment bolt 40 on the opposite side of the tool connection portion 42. In addition, the mounting component 50 has a retaining portion 51 that retains the ball head 43 of the adjustment bolt 40 so that it can rotate freely and the angle can be changed freely. It should be noted that the structure of the retaining portion 51 retaining the ball head 43 is not particularly limited. As the structure of the retaining portion 51 retaining the ball head 43, various known structures that retain the ball head in a universal joint so that it can rotate freely and the angle can be changed freely can be used. The ball head 43 and the retaining portion 51 can be freely detachable, and can also be non-detachable.

[0043] The adapter 100 is mounted on the mounting portion of the vehicle by screwing the male threaded portion 41 of the adjusting bolt 40 into each of the female threaded portions 30 of the first component 10, mounting the same number of mounting components 50 as the adjusting bolt 40 on the mounting portion of the vehicle, and holding the ball head 43 of each adjusting bolt 40 at the holding portion 51 of each mounting component 50. It should be noted that the mounting structure of the mounting component 50 on the mounting portion of the vehicle is not particularly limited, and in this embodiment, the mounting structure is as follows. The mounting component 50 has a first flange portion 52 and a second flange portion 53 of different heights. The mounting component 50 is mounted on the mounting portion of the vehicle by sandwiching a plate member of the mounting portion of the vehicle between the first flange portion 52 and the second flange portion 53.

[0044] When the adapter 100 is mounted on the mounting portion of the vehicle, a tool is connected to the tool connection portion 42 and each adjustment bolt 40 is rotated, so that the distance between the adapter 100 and the mounting portion of the vehicle can be changed at the position of each adjustment bolt 40. In this way, the angle of the adapter 100 relative to the mounting portion of the vehicle can be adjusted. In other words, the angle of the detection axis of the radar device 60 held on the adapter 100 relative to the mounting portion of the vehicle can be adjusted.

[0045] It should be noted that Figures 1 to 4When the male threaded portion 41 of the adjusting bolt 40 is screwed into the female threaded portion 30 from the rear of the first member 10 as shown, the adapter 100 is arranged in front of the mounting portion of the vehicle, and the tool connecting portion 42 of the adjusting bolt 40 protrudes to the front of the first member 10. Therefore, the angle of the adapter 100 relative to the mounting portion of the vehicle is adjusted from the front of the adapter 100. However, the method of adjusting the angle from the front of the adapter 100 is just an example.

[0046] Figure 5 It is an assembly perspective view of the adapter according to the embodiment of the present invention.

[0047] like Figure 5 As shown in the figure, when the male threaded portion 41 of the adjusting bolt 40 is screwed into the female threaded portion 30 from the front of the first component 10, the adapter 100 is arranged behind the mounting portion of the vehicle, and the tool connecting portion 42 of the adjusting bolt 40 protrudes to the rear of the first component 10. Therefore, the angle of the adapter 100 relative to the mounting portion of the vehicle can be adjusted from the rear of the adapter 100.

[0048] That is, the adapter 100 according to the present embodiment can adjust the angle of the adapter 100 relative to the mounting portion of the vehicle from both sides of the front and rear of the adapter 100, in other words, from both sides of the front and rear of the radar device 60. Depending on the mounting portion of the vehicle and the structure of the periphery of the mounting portion, there is a case where the installation space of the adapter 100 and the radar device 60 can be reduced when the adapter 100 is arranged in front of the mounting portion, and there is a case where the installation space of the adapter 100 and the radar device 60 can be reduced when the adapter 100 is arranged in the rear of the mounting portion. The adapter 100 according to the present embodiment can adjust the angle of the adapter 100 relative to the mounting portion of the vehicle from both sides of the front and rear of the adapter 100, so the installation space of the adapter 100 and the radar device 60 can be reduced.

[0049] It should be noted that the adapter 100 involved in this embodiment has three female threaded portions 30 and three adjusting bolts 40. However, the number of female threaded portions 30 is not limited to three, and the number of adjusting bolts 40 is not limited to three. As long as the distance between the adapter 100 and the mounting portion of the vehicle can be adjusted at at least three locations, the angle of the adapter 100 relative to the mounting portion of the vehicle can be adjusted. Therefore, as long as there are at least three female threaded portions 30, there may be four or more. Similarly, as long as there are at least three adjusting bolts 40, there may be four or more.

[0050] Here, in the adapter 100 involved in the present embodiment, all the female threaded portions 30 are provided on the first component 10. Not limited to this, a part of the female threaded portion 30 may be provided on the second component 20. However, by providing all the female threaded portions 30 on the first component 10, the following effects can be obtained. Specifically, when the radar device 60 having different lengths in the vertical direction as the opposing direction of the first component 10 and the second component 20 is maintained, the same first component 10 is used and the shape of the second component 20 is changed. In such a case, the mounting position of the adjustment bolt 40 at the mounting portion of the vehicle does not need to be changed for each radar device 60 having different lengths in the vertical direction, so the versatility of the adapter 100 is improved.

[0051] It should be noted that the same effect can be obtained even if all the female thread portions 30 are provided on the second member 20. Specifically, when the radar devices 60 having different lengths in the vertical direction are maintained, the same second member 20 is used and the shape of the first member 10 is changed. In such a case, the mounting position of the adjustment bolt 40 at the mounting portion of the vehicle does not need to be changed for each radar device 60 having different lengths in the vertical direction, so the versatility of the adapter 100 is increased.

[0052] Furthermore, by providing all the female screw portions 30 on the first component 10, the angle of the adapter 100 with respect to the mounting portion of the vehicle can be adjusted before the second component 20 is tightened and fixed to the first component 10, in other words, before the radar device 60 is held by the adapter 100. That is, the angle of the adapter 100 with respect to the mounting portion of the vehicle can be adjusted both in the state before the radar device 60 is held by the adapter 100 and in the state after the radar device 60 is held by the adapter 100. Therefore, the adjustment operation of the angle of the adapter 100 with respect to the mounting portion of the vehicle becomes easy. It should be noted that the same effect can be obtained by providing all the female screw portions 30 on the second component 20.

[0053] Furthermore, in the adapter 100 according to the present embodiment, when the adjustment bolts 40 are mounted on the female threaded portion 30, the adjustment bolts 40 are disposed on the outer peripheral side of the radar device 60. With such a configuration, the angle of the adapter 100 relative to the mounting portion of the vehicle can be adjusted both in the state before the radar device 60 is held by the adapter 100 and in the state after the radar device 60 is held by the adapter 100. Therefore, the angle adjustment operation of the adapter 100 relative to the mounting portion of the vehicle becomes easy.

[0054] In addition, in the adapter 100 involved in the present embodiment, a fixing female thread portion 31 is formed into which a fixing bolt inserted into a through hole of the mounting portion of the vehicle is screwed. Therefore, when there is no need to adjust the angle of the adapter 100 relative to the mounting portion of the vehicle, the adapter 100 can be mounted on the mounting portion of the vehicle without using the adjustment bolt 40. Therefore, when there is no need to adjust the angle of the adapter 100 relative to the mounting portion of the vehicle, the adapter 100 involved in the present embodiment can be miniaturized compared to an adapter in which the fixing female thread portion 31 is not formed. That is, the adapter 100 and the radar device 60 can be easily mounted. It should be noted that the number of the fixing female thread portions 31 is not particularly limited, and in the present embodiment, three fixing female thread portions 31 are formed.

[0055] In addition, in the adapter 100 according to the present embodiment, all the fixing female screw portions 31 are formed on the first member 10. Therefore, the adapter 100 can be mounted on the mounting portion of the vehicle 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, mounting the adapter 100 on the mounting portion of the vehicle becomes easier.

[0056] <How to hold the radar device using the adapter>

[0057] Next, a method of holding the radar device 60 using the adapter 100 will be described.

[0058] First, the radar device 60 is clamped between the first component 10 and the second component 20. Then, the male screw 1 is inserted into the through hole 23 of the second component 20 and screwed into the female screw portion 13 of the first component 10, and the second component 20 is tightened and fixed to the first component 10. As a result, the radar device 60 is clamped by the first support portion 12 of the first component 10 and the second support portion 22 of the second component 20, and is held by the adapter 100.

[0059] <How to install the adapter on the vehicle's mounting section>

[0060] Next, a method for mounting the adapter 100 on the mounting portion of the vehicle will be described. When the angle of the adapter 100 relative to the mounting portion of the vehicle needs to be adjusted, the adapter 100 is mounted on the mounting portion of the vehicle using the adjustment bolt 40. The adapter 100 is mounted on the mounting portion of the vehicle before the radar device 60 is held by the adapter 100 or after the radar device 60 is held by the adapter 100.

[0061] First, the male threaded portion 41 of the adjusting bolt 40 is screwed into each of the female threaded portions 30 of the first component 10, and the same number of mounting components 50 as the male threaded portions 41 are mounted on the mounting portion of the vehicle. Then, the adapter 100 is mounted on the mounting portion of the vehicle by making the holding portion 51 of each mounting component 50 hold the ball head 43 of each male threaded portion 41. It should be noted that the mounting component 50 may be mounted on the mounting portion of the vehicle after making the holding portion 51 of each mounting component 50 hold the ball head 43 of each male threaded portion 41.

[0062] After the adapter 100 is mounted on the mounting portion of the vehicle, a tool is connected to the tool connection portion 42 to rotate each adjustment bolt 40, thereby changing the distance between the adapter 100 and the mounting portion of the vehicle at the position of each adjustment bolt 40. Thus, the angle of the adapter 100 relative to the mounting portion of the vehicle can be adjusted.

[0063] When the angle of the adapter 100 relative to the vehicle mounting portion does not need to be adjusted, the adapter 100 is mounted on the vehicle mounting portion without using the adjustment bolt 40. The adapter 100 is mounted on the vehicle mounting portion before or after the radar device 60 is held by the adapter 100.

[0064] First, a fixing bolt is inserted into the through hole of the mounting portion of the vehicle. Then, with the adjustment bolts 40 removed from the female threaded portions 30, the fixing bolts inserted into the through holes of the mounting portion of the vehicle are screwed into the fixing female threaded portions 31 of the adapter 100, and the adapter 100 is mounted on the mounting portion of the vehicle.

[0065] <Effect of the adapter>

[0066] The adapter 100 according to the present embodiment is an adapter that is mounted on a mounting portion of a vehicle and holds a radar device 60. At least three female thread portions 30 are formed through the adapter 100. In addition, the adapter 100 has at least three adjustment bolts 40, one end of which is mounted on the mounting portion of the vehicle so that it can rotate freely and change its angle freely, and a male thread portion 41 that meshes with the female thread portion 30 is formed.

[0067] The adapter 100 according to the present embodiment can adjust the angle of the adapter 100 relative to the mounting portion of the vehicle from both the front and rear sides of the adapter 100 by changing the insertion direction of the adjustment bolt 40 into the female thread portion 30. That is, the adapter 100 according to the present embodiment can be arranged at both the front and rear sides of the mounting portion of the vehicle. Therefore, the adapter 100 according to the present embodiment can reduce the installation space of the adapter 100 and the radar device 60.

[0068] Preferably, the cross-sectional shape of the other end of the adjusting bolt 40 is a polygonal shape. By configuring in this way, the tool connecting portion 42 is formed at the other end of the adjusting bolt 40, and the installation work can be simplified.

[0069] Preferably, when the adjustment bolts 40 are mounted on at least three female threaded portions 30, that is, when the adjustment bolts 40 are mounted on all female threaded portions 30, the adjustment bolts 40 are arranged on the outer peripheral side of the radar device 60. By configuring the adapter 100 in this way, the angle of the adapter 100 relative to the mounting portion of the vehicle can be adjusted both in the state before the radar device 60 is held by the adapter 100 and in the state after the radar device 60 is held by the adapter 100. Therefore, the angle adjustment operation of the adapter 100 relative to the mounting portion of the vehicle becomes easy.

[0070] Preferably, the adapter 100 is formed with a fixing female thread portion 31 into which a fixing bolt inserted into a through hole of a mounting portion of a vehicle is screwed. By configuring the adapter 100 in this way, when there is no need to adjust the angle of the adapter 100 relative to the mounting portion of the vehicle, the adapter 100 can be made smaller than an adapter without the fixing female thread portion 31.

[0071] The adapter 100 involved in the present embodiment has been described above, but the adapter involved in the present invention is not limited to the description of the present embodiment, and only a part of the present embodiment may be implemented. For example, the adapter 100 involved in the present embodiment holds the radar device 60 by two components, namely, the first component 10 and the second component 20. However, this structure is only an example. In the past, adapters of various structures have been proposed as adapters for holding radar devices, such as adapters of a single-component structure that holds the radar device by means of a locking claw that protrudes forward from a base. In the adapter involved in the present invention, various structures can be adopted as the structure for holding the radar device. That is, the adapter involved in the present invention can obtain the above-mentioned effect regardless of the structure of holding the radar device.
