Abstract
Description
[Technical Field]
[0001] The present invention relates to a mounting member for a detection device that detects the surrounding conditions of a vehicle. [Background technology]
[0002] For example, as disclosed in Patent Document 1, a technology has been developed that monitors the sides of a vehicle using radar, cameras, etc. to avoid collision accidents with vehicles traveling alongside or obstacles on the side of the vehicle when changing lanes or turning at an intersection. Patent Document 1 discloses a detection device with a detection range on the side of the vehicle, which includes a radar that measures the distance to obstacles, etc. on the side of the vehicle, and a camera that monitors obstacles, etc. on the side of the vehicle. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-315601 Summary of the Invention [Problem to be solved by the invention]
[0004] However, mounting members for attaching detection devices such as radars and cameras to vehicles require strength and rigidity to suppress vibration of the detection devices while the vehicle is in motion, etc. While forming the mounting member from a plate member is effective in ensuring strength and rigidity, constructing the mounting member solely from a plate member may result in a complex structure and increase costs and weight.
[0005] The present invention has been devised in view of the above-mentioned problems, and one of its objects is to ensure strength and rigidity with a simple structure in a mounting member for a detection device. [Means for solving the problem]
[0006] The present invention has been made to solve at least part of the above problems, and can be realized as the following aspects or application examples.
[0007] (1) The mounting member for the detection device in this application example is a mounting member for a detection device that detects the surrounding conditions of a vehicle, and includes a base having four faces forming a rectangular closed cross section and attached to the frame of the vehicle, and a linear portion extending from the base and supported by two opposing faces of the four faces, to which the detection device is attached.
[0008] According to this application example, the base fixed to the frame has a closed cross section formed by four faces, ensuring rigidity and strength. Furthermore, the linear portion to which the detection device is attached has a support structure supported by two opposing faces of the four faces, ensuring support rigidity, and the structure can be simplified by extending from the base. Therefore, strength and rigidity can be ensured with a simple structure.
[0009] (2) In the mounting member for the detection device according to this application example, a vehicle part other than the detection device may also be mounted to the linear portion. With this configuration, the mounting member can function not only as a bracket for the detection device but also as a bracket for other vehicle components, thereby reducing the number of brackets used to mount vehicle components and improving the layout performance of vehicle components.
[0010] (3) In the mounting member for the detection device according to this application example, the linear portion may be formed of a pipe at least a portion of which has a double structure. This configuration allows the linear portion to have higher rigidity and strength than when the linear portion is formed from a pipe with a single-wall structure, thereby further increasing the support rigidity of the linear portion and further suppressing vibration of the detection device.
[0011] (4) In the mounting member for the detection device according to this application example, the linear portion may be formed of a pipe having a double structure extending from the area supported by the base to the area where the vehicle part is mounted. This configuration allows pinpoint reinforcement of the linear portion at the locations that are susceptible to stress and those that receive loads from vehicle components, thereby effectively suppressing vibrations in the detection device. Furthermore, by making the linear portion a single-layer structure outside the double-layered area, it is possible to reduce material and weight compared to when the entire linear portion is a double-layered structure.
[0012] (5) In the mounting member for the detection device according to this application example, the linear portion may extend linearly. This configuration reduces stress concentration in the linear portion and cuts material costs compared to when the linear portion extends in a curved shape. In addition, the straight linear portion makes it easier to attach vehicle components and facilitates the creation of a double structure.
[0013] (6) In the mounting member for the detection device according to this application example, the base may have a fixing surface that is fixed to the frame, and the four surfaces may be arranged with gaps between them and the frame. With this configuration, other components can be placed in the gaps between the four faces and the frame. As a result, the base can be fixed to the frame even in a limited space, and the gaps between the four faces and the frame can be used as placement space for other components. This improves the layout performance around the frame.
[0014] (7) In the mounting member for the detection device according to this application example, the base may have a reinforcing surface that connects the fixing surface and at least one of the four surfaces. With this configuration, the base is reinforced by the reinforcing surface, which further increases the rigidity and strength of the base. As a result, the base can more stably support the linear portion, thereby further suppressing vibration of the detection device.
[0015] (8) In the mounting member for the detection device according to this application example, the base may have a connection surface that extends in a direction intersecting the four surfaces and connects the four surfaces. With this configuration, the rigidity and strength of the base can be further increased by the connection surface, which allows the base to more stably support the linear portion, thereby further suppressing vibration of the detection device.
[0016] (9) In the mounting member for the detection device according to this application example, the connection surface may be formed by bending from one of the four surfaces and may be joined to the remaining three of the four surfaces by welding. This configuration reduces the number of parts required for the base and simplifies the molding process for the base compared to when the connecting surface is formed separately from all four surfaces. Furthermore, the connecting surface can be reliably connected to the remaining three of the four surfaces, thereby more reliably increasing the rigidity and strength of the base. [Effects of the Invention]
[0017] According to the present invention, the strength and rigidity of the mounting member for the detection device can be ensured with a simple structure. [Brief explanation of the drawings]

[0019] The following describes embodiments (aspects, application examples) of the present invention with reference to the drawings. The following embodiments are merely examples, and are not intended to exclude various modifications or applications of techniques not explicitly stated in the embodiments. The configurations of the following embodiments can be modified in various ways without departing from the spirit of the invention. Furthermore, they can be selected or combined as needed.
[0020] [1. Configuration] [1-1. Vehicles] As shown in Fig. 1, a mounting member 1 for a detection device according to this embodiment (application example) (hereinafter also simply referred to as "mounting member 1") is applied to a detection device 2 that detects the surrounding conditions of a vehicle 3. The vehicle 3 is, for example, a flatbed truck having a cab 31 with a driver's seat (not shown) and a loading platform 32 arranged behind the cab 31.
[0021] In this embodiment, the vehicle 3 is shown as a short-cab type truck with a single front axle, in which the cab 31 is shorter in the vehicle length direction D1 (front-rear direction) than a typical full-cab type. However, the vehicle 3 to which this mounting member 1 is applied is not limited to such trucks, and may be, for example, a full-cab type truck or a two-front axle vehicle. In the drawings, the front of the vehicle 3 is indicated by "FR," the top of the vehicle 3 is indicated by "UP," and the left side of the vehicle 3 is indicated by "LH."
[0022] The detection device 2 is a sensor, radar, lidar, camera, etc. that detects objects such as people and other vehicles within its detection range. Information on objects detected by the detection device 2 is used, for example, in a system that monitors areas around the vehicle 3 that are prone to becoming blind spots. Such a system may issue a warning to the driver or automatically brake the vehicle 3 as necessary.
[0023] The detection device 2 mounted on the vehicle 3 is subject to regulations regarding its detection range (e.g., illumination range) in order to ensure its detection performance. In other words, the mounting position of the detection device 2 on the vehicle 3 (e.g., height from the road surface, protrusion amount from the vehicle body, etc.) is limited in advance in order to ensure a certain level of detection performance. The detection devices 2 of this embodiment are provided on each of the left and right sides of the vehicle 3, and their mounting positions are regulated so that a predetermined area extending from the side (left or right) to the rear of the vehicle 3 is included in the detection range.
[0024] A pair of front tires 9 (wheels, only one of which is shown in FIG. 1) are disposed below the cab 31. Additionally, mudguards 6, which are curved mudguard members that fit the surfaces of the front tires 9, are disposed diagonally above and behind each front tire 9. Furthermore, flaps 7 made of thin rubber plates hang down from the mudguards 6 like an apron.
[0025] The vehicle 3 is provided with various frames 4 as skeletal members. The frame 4 of the vehicle 3 includes a pair of side rails 41 (only one is shown in FIG. 1) extending in the vehicle length direction D1, and a cab bridge 42 that supports the rear end of the cab 31 from below. Each side rail 41 has, for example, a channel shape. The pair of side rails 41 are arranged spaced apart from each other in the vehicle width direction D2 (left-right direction). The cab bridge 42 is provided in an inverted U-shape or an arch shape, and is arranged to straddle the pair of side rails 41.
[0026] Various devices are attached to each side rail 41 via appropriate brackets. As shown in Fig. 2, in this embodiment, a leaf spring 5, which is one element of the suspension, is attached to the side rail 41 via a spring bracket 33. The leaf spring 5 is disposed inward in the vehicle width direction D2 from the front tire 9 (wheel) of the vehicle 3, and supports the front tire 9 via an axle (not shown). The leaf spring 5 is supported by the side rail 41 by having both front and rear ends attached to the side rail 41 via the spring bracket 33, respectively.
[0027] The spring bracket 33 is fixed to an outer surface 43 (hereinafter also referred to as the "rail outer surface 43") of the side rail 41. The rail outer surface 43 is the surface of the side rail 41 that faces outward in the vehicle width direction D2. In the channel-shaped side rail 41, the web surface corresponds to the rail outer surface 43.
[0028] [1-2. Mounting parts] The mounting member 1 is a device for mounting the detection device 2 to the frame 4 of the vehicle 3. In this embodiment, a mounting member 1 applied to a detection device 2 provided on the left side of the vehicle 3 will be described in detail. However, the mounting member 1 can also be applied to a detection device 2 provided on the right side of the vehicle 3. Furthermore, the mounting member 1 is not limited to being applied to the left or right side of the vehicle 3, and may also be applied to a detection device provided in another location on the vehicle 3 (for example, the front or rear of the vehicle 3).
[0029] The mounting member 1 comprises a base 10 that is attached to the frame 4 of the vehicle 3, and a linear portion 20 that extends from the base 10 and to which the detection device 2 is attached. The base 10 is formed with a plate member to have a closed cross-sectional structure in order to ensure strength and rigidity. In contrast, the linear portion 20 is formed with a simple, elongated linear shape using a small amount of material in order to reduce costs. By combining this base 10 and linear portion 20, the mounting member 1 ensures strength and rigidity while reducing costs and weight.
[0030] The mounting member 1 is positioned in accordance with the mounting position of the detection device 2 while avoiding interference with other devices. The mounting member 1 of this embodiment is positioned taking into consideration not only the mounting position of the detection device 2 but also the positions of the mudguard 6 and the spring bracket 33, and is located rearward of the front tire 9.
[0031] 3 and 4, the base 10 of this embodiment has four faces 11 to 14 forming a rectangular closed cross section, a fixing face 15 fixed to the frame 4, reinforcing faces 51 to 54 connecting the fixing face 15 to the four faces 11 to 14, respectively, and a connecting face 16 connecting the four faces 11 to 14. Each of the faces 11 to 16 and 51 to 54 is formed, for example, in the shape of a flat plate having a uniform thickness.
[0032] Specifically, the four surfaces 11-14 are a base inner surface 11 and a base outer surface 12 that extend along the vehicle length direction D1 and the vehicle height direction D3 (vertical direction), and a base front surface 13 and a base rear surface 14 that extend along the vehicle width direction D2 and the vehicle height direction D3. A horizontal cross section (a cross section perpendicular to the vehicle height direction D3) of these four surfaces 11-14 forms a closed rectangle. The four surfaces 11-14 are joined by, for example, welding. Here, the four surfaces 11-14 are illustrated as being substantially rectangular. Note that in Figures 3 and 4, the boundary between the base rear surface 14 and a rear reinforcing surface 54 (described later) and the boundary between the base front surface 13 and a front reinforcing surface 53 (described later) are shown by two-dot chain lines for convenience.
[0033] The base inner surface 11 and the base outer surface 12 are disposed spaced apart from each other in the vehicle width direction D2 and face each other in the vehicle width direction D2. The base inner surface 11 is located outward from the side rail 41 in the vehicle width direction D2 and inward from the base outer surface 12 in the vehicle width direction D2. In this embodiment, through holes 17, 18 through which the linear portion 20 is inserted are formed at corresponding positions on the base inner surface 11 and the base outer surface 12, respectively. Meanwhile, the base front surface 13 and the base rear surface 14 are disposed spaced apart from each other in the vehicle length direction D1 and face each other in the vehicle length direction D1. The base front surface 13 is located forward of the base outer surface 12.
[0034] As shown in FIG. 2, the four surfaces 11 to 14 are arranged with gaps between them and the side rail 41. A spring bracket 33 is arranged in the gap between the four surfaces 11 to 14 and the side rail 41 (specifically, between the base inner surface 11 and the rail outer surface 43). The height positions (positions in the vehicle height direction D3) of the four surfaces 11 to 14 are set to correspond to the lower part 62 of the mudguard 6. The lower part 62 of the mudguard 6 here refers to a portion of the lower half of the mudguard 6 that includes the lower end part 61 of the mudguard 6. The lower part 62 of the mudguard 6 is provided in a planar shape that follows the vehicle height direction D3.
[0035] 3 and 4, the fixing surface 15 extends along the vehicle length direction D1 and vehicle height direction D3, similar to the base inner surface 11 and the base outer surface 12. As shown in Fig. 2, the fixing surface 15 is placed on the rail outer surface 43 from the outside in the vehicle width direction D2, and is fixed to the rail outer surface 43 by, for example, bolts 30 and nuts (not shown).
[0036] In this embodiment, the fixing surface 15 is disposed higher than the four surfaces 11 to 14 and inward in the vehicle width direction D2, and is located directly above the spring bracket 33. That is, the fixing surface 15 and the spring bracket 33 are aligned in the vehicle height direction D3. In this way, the fixing surface 15 is fixed to a limited space on the rail outer surface 43 so as not to interfere with the spring bracket 33.
[0037] 3 and 4, the reinforcing surfaces 51 to 54 extend between the four surfaces 11 to 14 and the fixing surface 15 to reinforce the base 10. Specifically, the reinforcing surfaces 51 to 54 include an inner reinforcing surface 51 connecting the upper edge of the base inner surface 11 to the lower edge of the fixing surface 15, an outer reinforcing surface 52 connecting the upper edge of the base outer surface 12 to the upper edge of the fixing surface 15, a front reinforcing surface 53 connecting the upper edge of the base front surface 13 to the front edge of the fixing surface 15, and a rear reinforcing surface 54 connecting the upper edge of the base rear surface 14 to the rear edge of the fixing surface 15.
[0038] The inner reinforcing surface 51 and the outer reinforcing surface 52 extend at an angle (slant) relative to the base inner surface 11 and the base outer surface 12, respectively. In contrast, the front reinforcing surface 53 and the rear reinforcing surface 54 extend in the same plane as the base front surface 13 and the base rear surface 14, respectively. In other words, the front reinforcing surface 53 corresponds to a surface obtained by extending the base front surface 13 in the same plane up to the front edge of the fixing surface 15, and the rear reinforcing surface 54 corresponds to a surface obtained by extending the base rear surface 14 in the same plane up to the rear edge of the fixing surface 15.
[0039] The inner reinforcing surface 51 extends obliquely upward and inward in the vehicle width direction D2 from the base inner surface 11, and then bends inward in the vehicle width direction D2 to connect to the lower edge of the fixing surface 15. In this embodiment, both front and rear end portions of the portion of the inner reinforcing surface 51 that is connected to the lower edge of the fixing surface 15 are cut out in a substantially rectangular shape.
[0040] On the other hand, the outer reinforcing surface 52 extends obliquely upward and inward in the vehicle width direction D2 from the base outer surface 12, and then bends inward in the vehicle width direction D2 to connect to the upper edge of the fixing surface 15. In this embodiment, an access hole 55 for fastening the bolt 30 (see FIG. 2) is formed in the area of the outer reinforcing surface 52 that overlaps with the fixing surface 15 when viewed from the outside in the vehicle width direction D2.
[0041] The front reinforcing surface 53 extends from an upper edge of the base front surface 13 in the vehicle width direction D2 to a front edge of the fixing surface 15 in the vehicle height direction D3, and is generally trapezoidal in shape. Similarly, the rear reinforcing surface 54 extends from an upper edge of the base rear surface 14 in the vehicle width direction D2 to a rear edge of the fixing surface 15 in the vehicle height direction D3, and is generally trapezoidal in shape.
[0042] The connecting surface 16 extends in a direction intersecting with the four surfaces 11 to 14. Here, the connecting surface 16 shown is one that extends along the vehicle length direction D1 and the vehicle width direction D2 and connects the four surfaces 11 to 14 at or near the lower edges of the four surfaces 11 to 14. Such connecting surface 16 can also be said to be a bottom surface that closes off the space surrounded by the four surfaces 11 to 14 from below.
[0043] The base 10 of this embodiment can be formed by combining three bendable plate members. For example, a first plate member can form the base outer surface 12 and the outer reinforcing surface 52, a second plate member can form the base front surface 13, the base rear surface 14, the fixing surface 15, the front reinforcing surface 53, and the rear reinforcing surface 54, and a third plate member can form the base inner surface 11, the inner reinforcing surface 51, and the connecting surface 16. In this case, in the third plate member, the connecting surface 16 is formed by bending from the base inner surface 11 (one of the four surfaces 11 to 14).
[0044] The plate members may be joined to one another by, for example, intermittent welding. When welding is used to join the plate members together, the connecting surface 16 formed by the third plate member is joined to each of the base outer surface 12, the base front surface 13, and the base rear surface 14 (the remaining three of the four surfaces 11 to 14) by welding.
[0045] 2, the linear portion 20 is a stay for installing the detection device 2 at a predetermined mounting position. In addition to its original function of supporting the detection device 2, the linear portion 20 of this embodiment also has the function of supporting the mudguard 6 and the function of supporting the pump assembly 8. Note that the mudguard 6 and the pump assembly 8 are each an example of a vehicle part different from the detection device 2.
[0046] The linear portion 20 is supported by two opposing surfaces of the four surfaces 11 to 14. In this embodiment, the linear portion 20 is exemplified as being supported by the base inner surface 11 and the base outer surface 12, which are opposed to each other. Specifically, the linear portion 20 is inserted into the through holes 17, 18 in the base inner surface 11 and the base outer surface 12, and is arranged in a state where it penetrates through the base inner surface 11 and the base outer surface 12. The linear portion 20 is fixed to each of the base inner surface 11 and the base outer surface 12, for example, by welding.
[0047] The linear portion 20 of this embodiment is formed of a pipe (hollow member) having at least a portion with a double structure, and extends linearly as a whole. Here, the linear portion 20 extending straight along the vehicle width direction D2 is illustrated. As shown in Fig. 5, the linear portion 20 is formed of, for example, an outer pipe 21 and an inner pipe 22 having different outer diameters.
[0048] The outer pipe 21 is a round pipe that is larger in diameter and longer than the inner pipe 22. On the other hand, the inner pipe 22 is a round pipe that is disposed inside the outer pipe 21 and reinforces a portion of the outer pipe 21 by giving it a double structure. The outer pipe 21 and the inner pipe 22 are fixed to each other, for example, by plug welding to welding holes 23 formed in the outer pipe 21. Note that the welding holes 23 are disposed inside the base 10 (the space surrounded by the four surfaces 11 to 14), and therefore cannot be seen from the outside.
[0049] Here, the region of the linear portion 20 that is supported by the base portion 10 is also referred to as the support region 24, the region where the mudguard 6 and the pump assembly 8 are attached is also referred to as the auxiliary region 25, and the region where the detection device 2 is attached is also referred to as the attachment region 26. In this embodiment, the support region 24, auxiliary region 25, and attachment region 26 are arranged in this order from the inside to the outside in the vehicle width direction D2. The outer pipe 21 is arranged over the entire range of the support region 24, auxiliary region 25, and attachment region 26. On the other hand, the inner pipe 22 is arranged in the range from the support region 24 to partway through the auxiliary region 25.
[0050] More specifically, the support region 24 is a region that includes two locations of the linear portion 20 that are fixed to the base inner surface 11 and the base outer surface 12, respectively. The support region 24 in this embodiment includes the inner end portion 27 of the linear portion 20 in the vehicle width direction D2. The entire support region 24 has a double structure formed by the outer pipe 21 and the inner pipe 22.
[0051] The auxiliary region 25 is a region of the linear portion 20 that includes two locations where a pair of mudguard brackets 35, 36 for attaching the mudguard 6 are fixed, and two locations where a pair of pump brackets 37 for attaching the pump assembly 8 are fixed. The auxiliary region 25 has a double structure formed by the outer pipe 21 and the inner pipe 22 in a portion that is inward in the vehicle width direction D2 from the midpoint between the pair of pump brackets 37. That is, the inner pipe 22 of this embodiment extends from the inner end 27 of the linear portion 20 in the vehicle width direction D2 to between the pair of pump brackets 37. The linear portion 20 of this embodiment has a double structure formed by the inner pipe 22 in the range from the support region 24 to the auxiliary region 25.
[0052] 2, the pair of mudguard brackets 35, 36 are, for example, V-shaped and are spaced apart from each other in the vehicle width direction D2. More specifically, the pair of mudguard brackets 35, 36 include an inner bracket 35 fixed to an inner end 63 of a lower portion 62 of the mudguard 6 in the vehicle width direction D2, and an outer bracket 36 fixed slightly inward of an outer end 64 of the lower portion 62 of the mudguard 6 in the vehicle width direction D2. The lower portion 62 of the mudguard 6 is attached to the linear portion 20 via the mudguard brackets 35, 36, and an upper portion of the mudguard 6 is attached to the cab bridge 42 via a bracket (not shown).
[0053] On the other hand, the pair of pump brackets 37 are each formed, for example, in a hat shape and are arranged spaced apart from each other in the vehicle width direction D2 between the pair of mudguard brackets 35, 36. The pump assembly 8 is, for example, a device for tilting the cab 31 and includes a base 81 fixed to the pump brackets 37 and various parts such as a pump body 82 and a pump cover 83 installed on the base 81. The pump assembly 8 is attached to the linear portion 20 via the pump brackets 37.
[0054] 5, the mounting region 26 is a region of the linear portion 20 that includes a portion where a sensor bracket 38 for mounting the detection device 2 is fixed. In this embodiment, the mounting region 26 includes the outer end portion 28 of the linear portion 20 in the vehicle width direction D2. Since the inner pipe 22 is not disposed in the mounting region 26, the entire mounting region 26 has a single-layer (single-layer) structure due to the outer pipe 21. The detection device 2 is mounted in the mounting region 26 via the sensor bracket 38.
[0055] The shape and arrangement of the sensor bracket 38 may be set as appropriate depending on the mounting position of the detection device 2. The mounting position of the detection device 2 is set, for example, so as to satisfy the above regulations while ensuring a gap between the detection device 2 and peripheral components such as the front tire 9 and mudguard 6. Here, an example is shown in which the detection device 2 is mounted at a mounting position below the linear portion 20 and outward in the vehicle width direction D2.
[0056] [2. Actions and Effects] (1) In the mounting member 1, a base 10 having four faces 11 to 14 forming a closed cross section is attached to the frame 4, and the detection device 2 is attached to a linear portion 20 extending from the base 10 and supported by two opposing faces of the four faces 11 to 14. Therefore, the base 10 fixed to the frame 4 can ensure rigidity and strength due to the closed cross section formed by the four faces 11 to 14. Furthermore, the linear portion 20 to which the detection device 2 is attached can ensure support rigidity by being supported by two opposing faces of the four faces 11 to 14, and the structure can be simplified by extending from the base 10. Therefore, the mounting member 1 can ensure strength and rigidity with a simple structure.
[0057] Furthermore, the mounting member 1 has a simple structure, which reduces the amount of material used, thereby enabling cost and weight reductions. Furthermore, the mounting member 1, which ensures strength and rigidity, suppresses vibration of the detection device 2, thereby ensuring the detection performance of the detection device 2. In particular, the linear portion 20, which is supported while penetrating two opposing surfaces of the four surfaces 11 to 14, ensures good support rigidity, thereby effectively suppressing vibration of the detection device 2.
[0058] (2) If a vehicle component other than the detection device 2 is attached to the linear portion 20, the mounting member 1 can function as a bracket for not only the detection device 2 but also the other vehicle component. This reduces the number of brackets for attaching vehicle components, thereby improving the layout performance of vehicle components. In particular, the mounting member 1 disposed near a wheel such as the front tire 9 is suitable as a support bracket (mudguard stay) for the mudguard 6. Furthermore, the mounting member 1 disposed near the cab 31 is suitable as a support bracket for the pump assembly 8 that tilts the cab 31.
[0059] (3) If the linear portion 20 is formed from a pipe having at least a double structure, the rigidity and strength of the linear portion 20 can be increased compared to when the linear portion 20 is formed from a pipe having a single structure as a whole. Therefore, the support rigidity of the linear portion 20 can be further increased, and vibration of the detection device 2 can be further suppressed. In particular, if at least the portion of the linear portion 20 that is supported by the base 10 (support region 24) has a double structure, the portion that is susceptible to stress is reinforced, and vibration of the detection device 2 can be effectively suppressed.
[0060] (4) If the linear portion 20 is formed of a pipe having a double structure in the range from the support region 24 supported by the base 10 to the auxiliary region 25 where the vehicle parts are attached, it is possible to pinpoint and reinforce the parts of the linear portion 20 that are prone to stress and the parts that receive loads from the vehicle parts. This effectively suppresses vibrations of the detection device 2. Furthermore, by making the linear portion 20 a single structure outside the double structure range, it is possible to reduce material and weight compared to when the entire linear portion 20 is a double structure.
[0061] (5) If the linear portion 20 extends linearly, stress concentration in the linear portion 20 can be reduced and material costs can be reduced compared to when the linear portion 20 extends curvedly. If the linear portion 20 were curved, for example, there would be a risk of stress concentration at the bent portion of the linear portion 20 if vibrations were severe during driving, and there would be a risk of increased production costs due to the more complex shape compared to a simple linear linear portion 20. In contrast, a linear linear portion 20 has a simpler structure than a curved linear portion 20, making it possible to suppress the above-mentioned stress concentration and reduce production costs. Furthermore, a linear linear portion 20 makes it easier to attach vehicle components and facilitates the creation of a double structure.
[0062] (6) If the fixing surface 15 that is fixed to the frame 4 is provided on the base 10 and the four surfaces 11 to 14 are arranged with gaps between them and the frame 4, other components (e.g., spring bracket 33) can be arranged in the gaps between the four surfaces 11 to 14 and the frame 4. In other words, if the base 10 is fixed to the frame 4 at a fixing surface 15 that is different from the four surfaces 11 to 14, the four surfaces 11 to 14 do not need to be in contact with the frame 4, and the four surfaces 11 to 14 can be arranged away from the frame 4. As a result, the base 10 can be fixed to the frame 4 even in a limited space, and the gaps between the four surfaces 11 to 14 and the frame 4 can be used as space for arranging other components. This improves the layout performance around the frame 4.
[0063] (7) If the base 10 is provided with reinforcing surfaces 51 to 54 that connect the fixing surface 15 to at least one of the four surfaces 11 to 14, the base 10 is reinforced by the reinforcing surfaces 51 to 54, thereby further increasing the rigidity and strength of the base 10. As a result, the base 10 can more stably support the linear portion 20. Therefore, vibration of the detection device 2 can be further suppressed.
[0064] (8) If a connecting surface 16 is provided that extends in a direction intersecting the four surfaces 11 to 14 and connects the four surfaces 11 to 14, the connecting surface 16 can further increase the rigidity and strength of the base 10. As a result, the base 10 can more stably support the linear portion 20. Therefore, vibration of the detection device 2 can be further suppressed.
[0065] (9) If the connecting surface 16 is bent and formed from one of the four surfaces 11 to 14, the number of parts of the base 10 can be reduced and the molding process of the base 10 can be simplified compared to when the connecting surface 16 is formed separately from all of the four surfaces 11 to 14. Furthermore, if the connecting surface 16 is joined to the remaining three of the four surfaces 11 to 14 by welding, the connecting surface 16 can be reliably joined to the remaining three of the four surfaces 11 to 14. This more reliably increases the rigidity and strength of the base 10.
[0066] [3. Other] The above-described configurations of the base 10 and the linear portion 20 are merely examples. The base 10 only needs to have at least four surfaces 11 to 14, and some or all of the above-described fixing surface 15, connecting surface 16, and reinforcing surfaces 51 to 54 may be omitted. Note that a base 10 from which the fixing surface 15 is omitted may be fixed to the rail outer surface 43 at one of the four surfaces 11 to 14 (for example, the base inner surface 11). The base 10 may be attached to the frame 4 of the vehicle 3, for example, the cab bridge 42.
[0067] The four surfaces 11 to 14 are not limited to a structure in which the horizontal cross section forms a closed cross section as described above, but may also be a structure in which the vertical cross section (a cross section perpendicular to the vehicle length direction D1 or the vehicle width direction D2) forms a closed cross section. Furthermore, the four surfaces 11 to 14 may be disposed in contact with the frame 4, for example, if interference with the spring bracket 33 does not pose a problem.
[0068] The fixing surface 15 may be positioned according to its positional relationship with the frame 4, and may be positioned, for example, below the four surfaces 11 to 14. The reinforcing surfaces 51 to 54 may have an appropriate shape according to the positional relationship between the fixing surface 15 and the four surfaces 11 to 14. The access hole 55 may be omitted from the outer reinforcing surface 52.
[0069] The connecting surface 16 may connect portions other than the lower edges of the four surfaces 11 to 14. The connecting surface 16 may be provided separately from each of the four surfaces 11 to 14 and then joined to the four surfaces 11 to 14 by, for example, welding, or may be formed by bending two or more of the four surfaces 11 to 14. The method of connecting the four surfaces 11 to 14 to the connecting surface 16 is not limited to welding.
[0070] The linear portion 20 may have any shape as long as it extends from the base portion 10. For example, instead of the hollow shape (pipe) as described above, it may have a solid shape (rod shape), or the cross section may be a shape other than a circle (for example, a polygon). Furthermore, the linear portion 20 may have a single structure as a whole, or may have a double or more multiple structure at least partially or as a whole.
[0071] The two surfaces of the base 10 that support the linear portion 20 need only face each other, and for example, instead of the above-mentioned base inner surface 11 and base outer surface 12, the base front surface 13 and base rear surface 14 may be used. Furthermore, the linear portion 20 may be supported by another surface (for example, any of the reinforcing surfaces 51 to 54) in addition to the opposing two of the four surfaces 11 to 14.
[0072] It is sufficient that at least the detection device 2 is attached to the linear portion 20, and the mudguard 6 and the pump assembly 8 do not have to be attached. Furthermore, the attachment position of the detection device 2 and other vehicle components on the linear portion 20 is not particularly limited, and for example, the detection device 2 may be attached inward in the vehicle width direction D2 relative to the other vehicle components. Furthermore, the attachment method of the detection device 2 and other vehicle components to the linear portion 20 is not particularly limited, and for example, the above-mentioned various brackets 35 to 38 may be omitted.
[0073] The mounting member 1 can be applied to various vehicles 3 equipped with a detection device 2. Furthermore, the detection device 2 to which the mounting member 1 is applied may be one that detects the surrounding conditions of the vehicle 3, and may be one that detects the surrounding conditions in front, behind, above, or below the vehicle 3, for example.
