Description

[Technical field]

[0001] This invention relates to a mounting structure for a detector whose detection range is the side of a vehicle having a sidegate. [Background technology]

[0002] In recent years, technologies for improving safety have been used that use detectors (sensors, radar, lidar, etc.) provided on the sides of a vehicle to detect other vehicles, bicycles, pedestrians, etc. that are present on the sides of the vehicle, and output an alarm to the driver of the vehicle or automatically brake the vehicle. For example, Patent Document 1 discloses a structure in which a surrounding information detection sensor is fixed to a mounting bracket fixed to the fender panel of the vehicle.

[0003] [Patent Document 1] JP 2020-082922 A Summary of the Invention [Problem to be solved by the invention]

[0004] In order to ensure detection, the above-mentioned detector may be regulated by regulations to protrude outward in the vehicle width direction beyond the vehicle body within a predetermined dimension. On the other hand, in vehicles such as trucks and trailers with a loading platform, a plate-shaped gate may be provided on the sides (left and right) of the loading platform in a rotatable (raised and lowered) manner to prevent the load from falling. In vehicles with such gates, if the detector is installed in a state where it protrudes outward in the vehicle width direction beyond the loading platform, there is a risk of interference with the tilted (opened) gate.

[0005] To avoid this interference, for example, the detector can be mounted in a position that does not overlap with the rotational trajectory of the gate; however, detectors are usually subject to regulations regarding their irradiation range (detection range), and it can be difficult in terms of layout to mount the detector in a position that satisfies these regulations while not interfering with surrounding components such as the tires, mudguards, and gate.

[0006] In order to avoid interference between the detector and the gate, it is possible to limit the rotation angle of the gate. However, if the gate cannot be fully tilted due to a large restriction on the rotation angle of the gate, this may lead to a decrease in workability such as loading and unloading. As described above, the conventional technology does not take into account the interference between the detector and the gate, so there is room for improvement in terms of ensuring both the detectability of the detector and the rotation angle of the gate when avoiding interference between the detector and the gate.

[0007] The present invention has been devised in consideration of the above-mentioned problems, and one of its objects is to provide a detector mounting structure that can ensure both the detectability of the detector and the rotation angle of the tilt. [Means for solving the problem]

[0008] The present invention has been made to solve at least part of the above problems, and can be realized in the following aspects or application examples. The detector mounting structure of this application example is a detector mounting structure whose detection range covers the side of a vehicle having a tailgate rotatably attached to the side of the cargo bed, and is characterized in comprising a stay having a base end fixed to the frame of the vehicle and a support portion extending from the base end and fixed to a mudguard of the vehicle, supporting the mudguard, and a bracket attached to the stay and having a mounting portion for mounting the detector at a position lower than the stay and outboard in the vehicle width direction that overlaps with the rotation trajectory of the tailgate in a side view of the vehicle.

[0009] According to this application example, the detector can be mounted on the outer side of the stay in the vehicle width direction, so that the detectability of the detector can be ensured. Also, the detector can be mounted at a position offset downward from the stay, so that the rotation angle of the gate can be ensured while avoiding interference between the detector and the gate.

[0010] In the detector mounting structure according to this application example, the support portion may have an extension portion that extends outward in a vehicle width direction beyond a fixed position relative to the mudguard, and the bracket may be attached to the extension portion.

[0011] In this case, since the bracket is attached to the extension that extends outward in the vehicle width direction from the fixed position to the mudguard, the detector can be mounted at a position that protrudes outward in the vehicle width direction from the stay, and the bracket can be made shorter. This makes it easier to ensure the strength of the bracket while ensuring the detectability of the detector.

[0012] In the detector mounting structure according to this application example, the mounting portion may be provided at approximately the same height as a lower end portion of the mudguard.

[0013] In this case, the detector can be mounted as low as possible and in a position that does not interfere with the flap (apron) hanging down from the mudguard, which allows a greater rotation angle of the gate and protects the detector from the swinging flap.

[0014] In the detector mounting structure according to this application example, the bracket may be composed of two parts, a plate member and a closed cross-section member.

[0015] In this case, assembly of the bracket is facilitated. Effect of the Invention

[0016] According to the present invention, it is possible to provide a detector mounting structure that can ensure both the detectability of the detector and the rotation angle of the tilt. [Brief description of the drawings]

[0018] The embodiments of the present invention will be described with reference to the drawings. The following embodiments are merely examples, and are not intended to exclude the application of various modifications and techniques not specified in the embodiments. The configurations of the following embodiments can be modified in various ways without departing from the spirit of the embodiments. In addition, they can be selected or combined as necessary.

[0019] In the drawings, "FR" indicates the front of the vehicle, "UP" indicates the top of the vehicle, and "LH" indicates the left when facing the front of the vehicle. Hereinafter, the front-to-rear direction of the vehicle will be referred to as the "vehicle length direction," the left-to-right direction of the vehicle will be referred to as the "vehicle width direction," and the up-down direction of the vehicle will be referred to as the "vehicle height direction."

[0020] [1. Configuration] [1-1. Vehicle] As shown in FIG. 1, a detector mounting structure 1 (hereinafter simply referred to as "mounting structure 1") according to this embodiment (application example) is applied to a vehicle 3 having a tailgate 2. The vehicle 3 is, for example, a flatbed truck having a cab 31 in which a driver's seat (not shown) is provided, and a loading platform 32 arranged behind the cab 31. In this embodiment, the vehicle 3 is shown as a short cab type front single axle truck in which the length of the cab 31 in the vehicle length direction D1 is shorter than that of a typical full cab type. However, the vehicle 3 to which this mounting structure 1 is applied is not limited to such a truck, and may be, for example, a trailer with a tailgate.

[0021] The mounting structure 1 is a structure for mounting a detector 8, whose detection range is the side of the vehicle 3, on a vehicle 3 having a sidegate 2. The detector 8 is a sensor, radar, lidar, or the like that detects objects such as people and other vehicles present within the detection range. Information on objects detected by the detector 8 is used, for example, in a system (BSA; Blind Spot Assist) that monitors the sides of the vehicle 3, which are prone to blind spots, and issues a warning to the driver as necessary, or a system (Active Side Guard Assist) that monitors the entire surroundings of the vehicle 3.

[0022] In order to ensure detectability, regulations are set forth regarding the detection range (e.g., irradiation range) of the detector 8 mounted on the vehicle 3. In other words, in order to ensure a certain level of detectability, the mounting position of the detector 8 on the vehicle 3 (e.g., height from the road surface, protrusion amount from the vehicle body that forms the maximum dimension in the vehicle width direction D2, etc.) is limited in advance.

[0023] The vehicle 3 is provided with various frames 4 as framework members and side guards 5 for preventing collision objects from being caught in the vehicle during a side collision. The frame 4 of the vehicle 3 includes a pair of side rails 41 extending in the vehicle length direction D1 and a cab bridge 42 supporting the rear end of the cab 31 from below. Each side rail 41 is, for example, channel-shaped. The pair of side rails 41 are disposed spaced apart from each other in the vehicle width direction D2. Only the left side rail 41 is shown in FIG. 1. Various devices (not shown) are fixed to each side rail 41 via appropriate brackets. On the other hand, the cab bridge 42 is provided in an inverted U-shape or an arch shape and is disposed across the pair of side rails 41.

[0024] The side guard 5 is disposed rearward of the front tire 9 and outboard of the side rail 41 in the vehicle width direction D2. In this embodiment, a side guard 5 disposed to the left of the left side rail 41 is illustrated. The side guard 5 is disposed outboard of various devices attached to the side rail 41 in the vehicle width direction D2, and has the function of protecting these devices. In the vehicle 3 of this embodiment, the side guard 5 is disposed on the left side as described above, while an ATS (After Treatment System) cover (not shown) that covers the exhaust purification device is disposed at a corresponding location on the right side (to the right of the right side rail 41).

[0025] The gate 2 is a plate-like member for preventing the fall of cargo placed on the loading platform 32, and is rotatably attached to each side (left and right) of the loading platform 32. The gate 2 can be moved between a closed position P1 where it stands up from the side of the loading platform 32 and an open position P2 where it folds down from the side of the loading platform 32 by rotating about a rotation axis C that extends in the vehicle length direction D1 along the side of the loading platform 32.

[0026] More specifically, as shown in Fig. 2, when viewed from the vehicle length direction D1, the tailgate 2 extends above the loading platform 32 and is oriented along the vehicle height direction D3 (vertical direction) in the closed position P1 shown by the dashed line, and when viewed from the vehicle length direction D1, the tailgate 2 extends below the loading platform 32 and is oriented slightly outward in the vehicle width direction D2 with respect to the vehicle height direction D3 in the open position P2 shown by the solid line. When viewed from the vehicle length direction D1, the rotation angle θ that the tailgate 2 in the open position P2 makes with respect to the tailgate 2 in the closed position P1 is ensured to be as large as possible (maximum 180°) from the viewpoint of workability such as loading and unloading. Note that Fig. 2 shows only the main components.

[0027] The swingarm 2 moves from the closed position P1 to the open position P2 by rotating downward and outward in the vehicle width direction D2, and moves from the open position P2 to the closed position P1 by rotating upward and outward in the vehicle width direction D2. The trace (three-dimensional area) that the swingarm 2 follows when moving between the closed position P1 and the open position P2 in this manner is called the "rotation trajectory T of the swingarm 2." The swingarm 2 can be fixed to each of the closed position P1 and the open position P2 by a fixing mechanism (not shown).

[0028] As shown in FIG. 3, a mudguard 6, which is a curved mudguard member that fits the surface of the front tire 9, is disposed diagonally above and rearward of each front tire 9. A flap 7 made of a thin rubber plate hangs down from the mudguard 6 like an apron. The flap 7 extends downward from a lower end 61 of the mudguard 6. The upper end of the flap 7 is a fixed end that is fixed to the mudguard 6, whereas the lower end is a free end that is not fixed to any member, and therefore, for example, it swings when it receives wind while traveling. Note that the side rails 41 are omitted in FIG. 3.

[0029] [1-2. Mounting structure] The mounting structures 1 are provided on the left and right sides of the vehicle 3, and have substantially the same (symmetrical) configuration on the left and right sides. For this reason, in this embodiment, the left mounting structure 1 will be mainly described, and a detailed description of the right mounting structure 1 will be omitted. 3, the mounting structure 1 includes a stay 10 that supports the mudguard 6, and a bracket 20 attached to the stay 10. In this embodiment, a pipe-shaped stay 10 and a bracket 20 formed by assembling two parts are illustrated as examples. However, the specific configurations of the stay 10 and the bracket 20 are not limited to this.

[0030] The stay 10 is a member for attaching the mudguard 6 to the frame 4 of the vehicle 3, and is also called a mudguard stay. The stay 10 has a base end 11 fixed to the frame 4, and a support part 12 extending from the base end 11 and fixed to the mudguard 6. Here, the support part 12 fixed to the lower part 62 of the mudguard 6 is illustrated. The base end 11 and the support part 12 are parts that fulfill the original role of the stay 10, that is, supporting the mudguard 6.

[0031] In this embodiment, the support portion 12 of the stay 10 of the mounting structure 1 has an extension portion 13 that extends outward in the vehicle width direction D2 beyond the fixed position relative to the mudguard 6. The extension portion 13 is a portion provided for fixing the bracket 20. That is, the stay 10 has the function of supporting the bracket 20, in addition to the function of supporting the mudguard 6. Hereinafter, the "extension portion 13 of the support portion 12" will also be referred to as the "extension portion 13 of the stay 10".

[0032] A base end 11 of the stay 10 extends, for example, along the vehicle height direction D3 and is fixed to the frame 4 via a hat-shaped base end bracket 14. In the left mounting structure 1, the base end 11 of the stay 10 is fixed to a side rail 41 (not shown in FIG. 3).

[0033] The support portion 12 of the stay 10 smoothly curves from the base end portion 11 and extends along the vehicle width direction D2, and is fixed to the lower portion 62 of the mudguard 6 via a pair of V-shaped mudguard brackets 15, 16. The positions at which the mudguard brackets 15, 16 are provided correspond to the fixed positions of the support portion 12 relative to the mudguard 6. The pair of mudguard brackets 15, 16 are, in detail, an inner bracket 15 fixed to an inner end 63 of the lower portion 62 of the mudguard 6 in the vehicle width direction D2, and an outer bracket 16 fixed slightly inward of an outer end 64 of the lower portion 62 of the mudguard 6 in the vehicle width direction D2. The inner bracket 15 and the outer bracket 16 are disposed apart from each other in the vehicle width direction D2. The lower portion 62 of the mudguard 6 here refers to a portion including the lower end portion 61 of the mudguard 6 in the lower half of the mudguard 6. The lower portion 62 of the mudguard 6 is provided in a planar shape that is substantially along the vehicle height direction D3.

[0034] The extending portion 13 of the stay 10 extends along the vehicle width direction D2 at the support portion 12 and protrudes outward in the vehicle width direction D2 beyond the outer bracket 16. A bracket 20 is attached to the extending portion 13 of the present embodiment by, for example, welding.

[0035] The bracket 20 is a member for mounting the detector 8, and therefore can be called a sensor bracket, and can also be called a BSA bracket when the detector 8 is used for BSA. The bracket 20 has a mounting portion 21 for mounting the detector 8 at a predetermined position. The predetermined position for mounting the detector 8 is a position that is lower than the stay 10 and outside in the vehicle width direction D2, and overlaps with the rotation trajectory T of the tailgate 2 in a side view of the vehicle 3 (as viewed from the vehicle width direction D2). This predetermined position is set so as to satisfy regulations regarding the detection range of the detector 8 and to ensure a gap between the detector 8 and peripheral members such as the front tire 9 and the mudguard 6. Here, a position set lower than the extension portion 13 of the stay 10 and outside in the vehicle width direction D2 is exemplified as the predetermined position.

[0036] In this embodiment, the height position of the mounting portion 21 is set so that the detector 8 is mounted at the same (approximately the same) height as the lower end 61 of the mudguard 6. In other words, the mounting portion 21 is arranged so that the detector 8 is mounted above the flap 7 hanging down from the mudguard 6 or at a height near the upper end of the flap 7. More specifically, the lower end of the detector 8 and the lower end 61 of the mudguard 6 are set at approximately the same height (see FIG. 1). By arranging the mounting portion 21 in this way, interference between the detector 8 and the flap 7, which may swing, is avoided.

[0037] 4, in this embodiment, the position of the mounting portion 21 in the vehicle width direction D2 is set so that the detector 8 is mounted protruding outward in the vehicle width direction D2 beyond the side guards 5 and the mudguards 6. Such an arrangement of the mounting portion 21 prevents the side guards 5 and the mudguards 6 from significantly encroaching into the detection range of the detector 8. The mounting portion 21 is disposed with a gap between each of the side guards 5 and the mudguards 6.

[0038] As shown in Fig. 5, the bracket 20 of this embodiment is composed of two parts, a closed cross-section member 22 and a plate member 23. The closed cross-section member 22 has a rectangular closed cross-section structure, and has a pair of annular portions 24 in which through holes are formed, through which the extension portions 13 of the stays 10 are inserted. The closed cross-section member 22 further has a plurality of bolt holes 25 through which bolts 30 for joining to the plate member 23 are inserted, and a plurality of lightening holes 26 for weight reduction. Weld nuts (not shown) are fixed to the inside (within the closed cross section) of each bolt hole 25 of the closed cross-section member 22.

[0039] The closed cross-section member 22 is disposed in a position in which the annular portions 24 are located above the bolt holes 25, and is fixed to the extending portions 13 of the stay 10 with the extending portions 13 of the stay 10 passing through each of the annular portions 24. Therefore, when the closed cross-section member 22 is fixed to the stay 10, the bolt holes 25 are located below the extending portions 13 of the stay 10. In other words, the closed cross-section member 22 extends downward from the extending portions 13 of the stay 10.

[0040] The plate member 23 is a rectangular plate in which a plurality of bolt holes 27 through which bolts 30 are inserted, mounting holes 28 for mounting the detector 8, and positioning holes 29 for positioning the detector 8 are formed. In the plate member 23, the mounting holes 28 and the positioning holes 29 are formed on the opposite side to the bolt holes 27 (the left side in FIG. 5). The mounting holes 28 and the positioning holes 29 are the portions where the detector 8 is mounted, and therefore they particularly function as the mounting portion 21. Note that the detector 8 is provided with mounting holes and positioning protrusions (not shown) at locations corresponding to the mounting holes 28 and the positioning holes 29 of the plate member 23, respectively.

[0041] The plate member 23 is joined to the closed cross-section member 22 fixed to the extension portion 13 of the stay 10, after the detector 8 has been attached in advance to the mounting hole 28 and the positioning hole 29. At this time, the plate member 23 is disposed in a position in which the mounting hole 28 and the positioning hole 29 (i.e., the detector 8 attached to the plate member 23) are located outside the bolt hole 27 in the vehicle width direction D2. The closed cross-section member 22 and the plate member 23 are positioned so that the bolt holes 25, 27 overlap each other, and then the bolt 30 is inserted from the plate member 23 side and screwed into the weld nut of the closed cross-section member 22, thereby joining them to each other.

[0042] Although not shown in the drawings, the mounting structure 1 provided on the right side of the vehicle 3 is different from the left mounting structure 1 in that the base end 11 of the stay 10 is fixed to another location on the frame 4, but the other points are the same. In this way, when it is difficult to fix the base end 11 of the stay 10 to the side rail 41 in relation to the surrounding members, it may be fixed to the frame 4 other than the side rail 41. Since an ATS cover is provided on the right side of the vehicle 3 instead of the above-mentioned side guard 5, in the right mounting structure 1, the position of the mounting portion 21 of the bracket 20 is set so that the detector 8 is mounted protruding outward in the vehicle width direction D2 beyond the ATS cover and the mudguard 6. The mounting portion 21 of the right mounting structure 1 is disposed with a gap from each of the ATS cover and the mudguard 6.

[0043] [2. Actions and Effects] In order to avoid interference with peripheral components such as the front tire 9, side guard 5, and mudguard 6 while satisfying regulations regarding the detection range, the detector 8 may have to be installed at a position overlapping with the rotation trajectory T of the swingarm 2 in a side view of the vehicle 3. On the other hand, although it is desirable to secure the rotation angle θ of the swingarm 2 as large as possible from the viewpoint of workability, for example, in loading and unloading using a forklift, the rotation angle θ may be limited in order to avoid interference with the detector 8.

[0044] For example, as shown by the two-dot chain line in Fig. 2, it is assumed that the detector 8' according to the comparative example is installed above the above-mentioned detector 8 in the area below the rotation axis C of the swing-up lever 2. In this case, the rotation angle θ of the swing-up lever 2 is significantly restricted in order to avoid interference with the detector 8', and the rotation angle θ is only about 155° at the open position P2' in this comparative example. It is also possible to set the detector 8' back inside in the vehicle width direction D2 in order to avoid interference with the swing-up lever 2, but in that case, peripheral members are likely to enter the detection range of the detector 8', which may result in the detector 8' not satisfying the regulations regarding the detection range.

[0045] In contrast, according to the above mounting structure 1, the bracket 20 attached to the stay 10 supporting the mudguard 6 is provided with a mounting portion 21 for mounting the detector 8 below the stay 10 and outside the vehicle width direction D2. Such a mounting portion 21 allows the detector 8 to be mounted outside the stay 10 in the vehicle width direction D2, ensuring the detectability of the detector 8. Also, since the detector 8 can be mounted at a position offset below the stay 10, the rotation angle θ of the swingarm 2 can be ensured while avoiding interference between the detector 8 and the swingarm 2 tilted (opened) to the open position P2. Therefore, both the detectability of the detector 8 and the rotation angle θ of the swingarm 2 can be ensured. In the example of this embodiment, the open angle θ is ensured to be up to about 170°.

[0046] Furthermore, if the bracket 20 is attached to the extending portion 13 that extends outward in the vehicle width direction D2 from the fixed position (the inner bracket 15 and the outer bracket 16) of the support portion 12 relative to the mudguard 6, the detector 8 can be mounted at a position that protrudes outward in the vehicle width direction D2 from the stay 10, and the bracket 20 can be made shorter. This makes it easier to ensure the strength of the bracket 20 while ensuring the detectability of the detector 8.

[0047] If the height of the mounting portion 21 is set so that the detector 8 is mounted at the same (approximately the same) height as the lower end portion 61 of the mudguard 6, it is possible to prevent interference between the detector 8 and the flap 7 hanging down from the mudguard 6, while offsetting the detector 8 downward from the extension portion 13 of the stay 10. Therefore, it is possible to ensure the rotation angle θ of the gate 2 and to protect the detector 8 from the flap 7 which may swing.

[0048] If the bracket 20 is composed of two parts, the closed cross-section member 22 and the plate member 23, assembly of the bracket 20 becomes easier, improving the ease of mounting the detector 8 to the vehicle 3. For example, the detector 8 can be mounted on the vehicle 3 by previously mounting the detector 8 to the plate member 23 and fixing the closed cross-section member 22 to the extension portion 13 of the stay 10, and finally joining the closed cross-section member 22 and the plate member 23. Therefore, even if the mounting space for the detector 8 is small, the mounting work is easy.

[0049] [3.Other] The stay 10 and bracket 20 shown in the above embodiment are just an example. The stay 10 does not have to be pipe-shaped, and the bracket 20 does not have to be composed of two parts, the closed cross-section member 22 and the plate member 23. In addition, the base end portion 11 of the stay 10 may be fixed to the frame 4 other than the side rail 41 or the cab bridge 42. Note that the method of fixing the stay 10 to the side rail 41 or the mudguard 6 is not limited to the method using the various brackets 14 to 16 described above, and when another method is used, the various brackets 14 to 16 described above can be omitted. In addition, in the above embodiment, an example is shown in which the bracket 20 is attached to the extension portion 13 of the stay 10, but this is not limited to this, and the bracket 20 may be attached, for example, between the respective fixed positions of the inner bracket 15 and the outer bracket 16 in the support portion 12.

[0050] There is no particular limitation on the method of fixing the detector 8 to the mounting portion 21 of the bracket 20. The mounting portion 21 may be any portion on which the detector 8 is mounted, and the specific structure thereof is not limited to the attachment holes 28 and positioning holes 29 described above. The mounting structure 1 can be applied to various vehicles 3 having tailgates 2, and may be applied to, for example, a truck having a wing-type van body (luggage compartment).

[0051] In this specification, the device referred to as BSA (Blind Spot Assist) is called by various names. In addition to BSA, such a device is also called, for example, BSM (Blind Spot Monitoring). Therefore, the term "BSA" in this specification may be replaced with other well-known names such as "BSM." In addition, in this specification, "BSA" may be a device that issues an alarm to the driver when a person, another vehicle, etc. is detected to the side of the vehicle, or, instead of or in addition to the above-mentioned alarm, may be a device that performs control such as braking control or steering control on the vehicle when a person, another vehicle, etc. is detected to the side of the vehicle.
