DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] [Structure of temporary holding structure S] Fig. 1 is a diagram showing a state before a component 2 is suspended from a frame 1 in a temporary holding structure S according to this embodiment. Fig. 1 also shows a state in which the component 2 is fixed to the frame 1 (bolts and nuts are omitted). Fig. 2 is a diagram showing a state in which the component 2 is suspended from a frame 1 in the temporary holding structure S according to this embodiment. Fig. 2 is a diagram showing a state in which the component 2 has rotated from the state of the component 2 in Fig. 1 with a first region 311 that has passed through a hole 11 as a support point.

[0013] Fig. 3 is a diagram showing the structure of the hook 3. Fig. 3(a) is a diagram showing the hook 3 in Fig. 1 as viewed from the inside in the vehicle width direction, and Fig. 3(b) is a diagram showing the hook 3 in Fig. 1 as viewed from the rear in the vehicle front-rear direction.

[0014] The temporary holding structure S is a structure for temporarily holding a vehicle component 2 to the frame 1 when fixing the component 2 to the vehicle frame 1. By temporarily holding the component 2 to the frame 1, a worker can release his / her hands from the component 2, improving the workability when fixing the component 2 to the frame 1.

[0015] The temporary holding structure S has a frame 1, a part 2, and a hook 3. The frame 1 is a frame of a vehicle. The frame 1 is, for example, a side frame extending in the front-rear direction of the vehicle. The vehicle is provided with a plurality of side frames in the vehicle width direction.

[0016] The frame 1 has a U-shaped cross section. The frame 1 has a region extending in the height direction of the vehicle and regions extending inward in the vehicle width direction from the upper and lower ends of the region.

[0017] The frame 1 has a hole 11 and a plurality of holes 12. The hole 11 is a hole through which a tip portion 31 of a hook 3 described later is passed. The hole 11 is an elongated hole formed to extend in the horizontal direction. The hole 11 is an elongated hole formed to extend in the front-rear direction of the vehicle.

[0018] The holes 12 are holes into which bolts are inserted for fixing the component 2 to the frame 1. The multiple holes 12 are provided below the holes 11. The multiple holes 12 are spaced apart from each other in the front-rear direction of the vehicle.

[0019] The part 2 is fixed to the frame 1. The part 2 is fixed to the outer side of the frame 1 in the vehicle width direction. The part 2 is, for example, a noise cover. The noise cover is a part for reducing noise from a sound source by covering the sound source that generates noise in the vehicle. The sound source is, for example, provided between a plurality of side frames. The sound source includes, for example, an engine, a motor, a transmission, an exhaust pipe, etc.

[0020] The component 2 has a component body 21 and a plurality of fixing portions 22. The component body 21 includes a plate-shaped region extending in the front-rear direction of the vehicle. The component body 21 is located outside, in the vehicle width direction, a sound source that generates vehicle noise.

[0021] The multiple fixing portions 22 are components for fixing the component body 21 to the frame 1. The fixing portions 22 include, for example, an area extending in the height direction of the vehicle, and the area is fixed to an outer surface of the component body 21 in the vehicle width direction of the vehicle. The upper ends of the fixing portions 22 are located higher than the upper end of the component body 21.

[0022] The component 2 is provided with a first fixing portion 22A and a second fixing portion 22B as a plurality of fixing portions 22. The first fixing portion 22A is provided on one end side in the horizontal direction of the component 2. The first fixing portion 22A has a recess 221A. The recess 221A is provided at a position above the upper end of the component body 21 in the first fixing portion 22A.

[0023] The second fixing portion 22B is provided on the other end side in the horizontal direction of the component 2. The second fixing portion 22B has a hole 221B. The hole 221B is provided at a position above the upper end of the component body 21 in the second fixing portion 22B.

[0024] In the state shown in FIG. 1, the part 2 is fixed to the frame 1 by inserting a bolt into the recess 221A of the first fixing part 22A and the hole 12 of the frame 1 and tightening a nut onto the inserted bolt, and by inserting a bolt into the hole 221B of the second fixing part 22B and the hole 12 of the frame 1 and tightening a nut onto the inserted bolt.

[0025] The hook 3 is a part for temporarily holding the part 2 on the frame 1. The hook 3 is formed of, for example, a pipe material or a bar material. The hook 3 is provided at a position horizontally offset from the position of the center of gravity C of the part 2 when the part 2 is in the mounting orientation as shown in FIG. 1. The hook 3 is provided on the other end side of the part 2 in the horizontal direction. The hook 3 extends upward from the part 2. The hook 3 is provided at the upper end of the second fixing portion 22B, and extends upward from the upper end of the second fixing portion 22B.

[0026] The hook 3 has a tip 31. The tip 31 is passed through a hole 11 provided in the frame 1.

[0027] The tip portion 31 has a first region 311 and a second region 312. The first region 311 is a region that extends through the hole 11. The first region 311 extends, for example, in a direction that intersects with the frame 1 in a state in which the part 2 is fixed to the frame 1 (FIG. 1).

[0028] As shown in Fig. 1, the second region 312 is a region that extends from the first region 311 so as to bend toward the position of the center of gravity C of the part 2 in the horizontal direction. One end of the second region 312 is connected to an end of the first region 311. In the state of Fig. 1, the second region 312 is located inside the frame 1. In this example, the second region 312 includes a linear region. By including such a linear region in the second region 312, a straight line portion used as a gripping allowance when forming the hook 3 from, for example, a pipe material or a bar material with a bender can be used as it is as the straight line region of the second region 312.

[0029] Since the second region 312 is bent horizontally from the first region 311 as described above, the following advantages are obtained. It is also possible that the second region is not bent as in this embodiment, and a "J"-shaped hook is used, for example. In the case of such a hook, the portion corresponding to the second region 312 extends in the height direction of the vehicle. In this configuration, it is necessary to increase the height dimension of the hole 11 of the frame 1 in order to hook the hook into the hole. In contrast, according to the configuration of this embodiment, since the second region 312 is bent, as can be seen from FIG. 3(a), the height dimension of the second region 312 in the state of FIG. 3(a) is reduced. Therefore, it is not necessary to increase the height dimension of the hole 11 of the frame 1.

[0030] When component 2 is suspended from frame 1 with first region 311 passing through hole 11 as a support point, component 2 tilts due to its own weight as shown in Fig. 2. Tip portion 31 is formed such that in this state, the end of second region 312 is positioned below hole 11. The bending angle and length of second region 312 may be designed so as to satisfy the above conditions, assuming a state in which component 2 is suspended.

[0031] In the temporary holding structure S, as described above, the tip 31 of the hook 3 includes a second region 312 that extends so as to bend from a first region 311 extending through the hole 11 toward the position of the center of gravity C of the part 2 in the horizontal direction, and is formed so that the end of the second region 312 is positioned below the hole 11 when the part 2 is suspended from the frame 1 with the first region 311 that has passed through the hole 11 as a support point.

[0032] As a result, in the temporary holding structure S, even if the worker releases the part 2, the tip 31 of the hook 3 will not come out of the hole 11 while the part 2 is suspended from the frame 1, and the part 2 can be favorably held on the frame 1. Therefore, the part 2 can be temporarily held on the frame 1 by the hook 3 at one location, and the part 2 can be prevented from falling off the frame 1. Therefore, the part 2 can be favorably temporarily held on the fixed member with a simple structure.

[0033] Specifically, tip portion 31 is formed such that an end of second region 312 is closer to the position of center of gravity C of component 2 before it is hung than line L connecting the point where first region 311 contacts hole 11 and center of gravity C of the hung component 2. In temporary holding structure S, tip portion 31 is formed in this manner, so that second region 312 can be smoothly passed through hole 11 while component 2 is hung from frame 1, making it difficult for component 2 to fall from frame 1.

[0034] The hook 3 has a connection region 32. The connection region 32 is a region having one end fixed to the component 2 and the other end connected to the tip portion 31. The connection region 32 extends on the side of the frame 1 where the component 2 is fixed. The connection region 32 extends on the outer side in the vehicle width direction of the region of the frame 1 extending in the vehicle height direction.

[0035] The connection region 32 has a first portion 321 and a second portion 322. The first portion 321 is a portion that extends upward from the component 2. When the component 2 is fixed to the frame 1 (FIG. 1), the first portion 321 extends in the height direction of the vehicle.

[0036] The second portion 322 is a portion bent from the first portion 321 toward the position of the center of gravity C of the part 2 (toward the left side in FIG. 1). One end of the second portion 322 is connected to the upper end of the first portion 321. The other end of the second portion 322 is connected to the outer end of the first region 311 in the vehicle width direction. In a state in which the part 2 is fixed to the frame 1 (FIG. 1), the second portion 322 is inclined with respect to the height direction of the vehicle such that the other end of the second portion 322 is closer to the position of the center of gravity C of the part 2 in the horizontal direction than the one end of the second portion 322.

[0037] By bending second portion 322 relative to first portion 321 in this manner, the horizontal distance between the point where first region 311 contacts hole 11 and the center of gravity C of part 2 becomes closer, so that the angle by which part 2 rotates from the state before part 2 is hung from frame 1 to the state in which part 2 is hung from frame 1 can be suppressed.

[0038] Tip portion 31 is formed so that the height dimension of second region 312 is shorter than the height dimension of hole 11 when component 2 is in a state before being suspended. In temporary holding structure S, tip portion 31 of hook 3 is formed in this manner, which makes it easier to insert tip portion 31 of hook 3 into hole 11. Also, it is possible to prevent the height dimension of hole 11 from becoming large.

[0039] [Effects of the temporary holding structure S according to this embodiment] In the temporary holding structure S of this embodiment, as described above, the tip 31 of the hook 3 includes a second region 312 that extends so as to bend from a first region 311 extending through the hole 11 toward the position of the center of gravity C of the part 2 in the horizontal direction, and is formed so that the end of the second region 312 is positioned below the hole 11 when the part 2 is suspended from the frame 1 with the first region 311 that has passed through the hole 11 as a support point.

[0040] As a result, in the temporary holding structure S, even if the worker releases the part 2, the tip 31 of the hook 3 will not come out of the hole 11 while the part 2 is suspended from the frame 1, and the part 2 can be favorably held on the frame 1. Therefore, the part 2 can be temporarily held on the frame 1 by the hook 3 at one location, and the part 2 can be prevented from falling off the frame 1. Therefore, the part 2 can be favorably temporarily held on the fixed member with a simple structure.

[0041] In this embodiment, an example has been described in which a hole is formed in the frame 1 itself, but a hole may also be provided in the frame 1 by forming a hole in a specified member attached to the frame 1.

[0042] Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of the gist of the present invention. For example, all or part of the device can be configured by distributing or integrating functionally or physically in any unit. In addition, new embodiments resulting from any combination of multiple embodiments are also included in the embodiments of the present invention. The effect of the new embodiment resulting from the combination combines the effect of the original embodiment. [Explanation of symbols]
