It is a side view of the oil level gauge tube fixing structure. It is a figure which shows a guide member in a standalone state.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an oil level gauge tube fixing structure of this embodiment provided in a vehicle. FIG. 2 is a perspective view of the oil level gauge tube fixing structure viewed from the rear side of the vehicle. In the drawings of this application, front, rear, left, and right correspond to the front, rear, left, and right of the vehicle, respectively. Upper corresponds to vertically upward, and lower corresponds to vertically downward.

As shown in FIGS. 1 and 2, the oil level gauge tube fixing structure S100 includes an oil level gauge tube 10, a bracket assembly 20, a fixture C1, a fixture C2, and a guide member 30. .

The oil level gauge tube 10 is a cylindrical member in which an oil level gauge 11 is housed. The oil level gauge tube 10 has flexibility. The oil level gauge tube 10 is attached to at least one component of the vehicle. In the range shown in FIG. 1, the oil level gauge tube 10 is fixed, for example, to a plate 42 provided near a reserve tank 41 via a bracket assembly 20.

The side of the oil level gauge tube 10 into which the oil level gauge 11 is inserted is the end side of the oil level gauge tube 10. Although the base end side of the oil level gauge tube 10 is not shown in FIG. 1, it is connected to the engine. The oil level gauge tube 10 is arranged so that the position of the tube becomes gradually higher as it goes from the proximal end to the distal end.

The bracket assembly 20 is a member for fixing a part of the oil level gauge tube 10 to a plate 42 that is a component of the vehicle. In this embodiment, the bracket assembly 20 includes a support bracket 21 and a fixing member 25, as shown in FIG. Both the support bracket 21 and the fixing member 25 are, for example, sheet metal members.

The support bracket 21 has an elongated plate shape that extends in a direction generally along the direction in which the oil level gauge tube 10 extends. The support bracket 21 is a member that supports the guide member 30, the fixture C1, and the fixture C2. The support bracket 21 includes a first region 21a and a second region 21b as a portion near the guide member 30.

The first region 21a extends in a direction (first direction) that is generally parallel to the left-right direction of the vehicle. Specifically, the first region 21a is provided in such a direction that the side surface of the flat plate extends in the vertical direction of the vehicle.

The second region 21b is a portion bent from the first region 21a, and extends in a second direction intersecting the first direction. Specifically, the second region 21b extends diagonally from the front toward the rear of the vehicle. Similarly to the first region 21a, the second region 21b is also provided in such a direction that the side surface of the flat plate extends in the vertical direction.

The fixing member 25 is fixed to the support bracket 21, and the fixing member 25 and the support bracket 21 constitute one bracket assembly 20. The fixing member 25 has an attachment surface 25a that is attached to the plate 42. A through hole 25h through which a fixing screw is passed is formed in the mounting surface 25a. The bracket assembly 20 is attached to the plate 42 by screwing the fixing screw passed through the through hole 25h into the plate 42.

The fixture C1 and the fixture C2 are members for fixing the oil level gauge tube 10. The fixture C1 is located closer to the base end of the oil level gauge tube 10 than the guide member 30 is. The fixture C2 is located closer to the distal end of the oil level gauge tube 10 than the guide member 30 is. Although not limited to this, the fixture C2 may have a base portion C2a and a holding portion C2b, as shown in FIG. The base portion C2a has a hole through which a fixing bolt is passed, for example. The holding portion C2b surrounds and supports a portion of the oil level gauge tube 10. The support bracket 21 may have a support portion 21c that supports the fixture C2 with the base portion C2a facing upward and the holding portion C2b facing downward. Such a support portion 21c may be formed at the end of the support bracket 21, and the support portion 21c may be provided so as to be located above the oil level gauge tube 10.

The oil level gauge tube 10 is arranged so that its height gradually increases from the proximal end to the distal end. Therefore, the position of fixture C2 is higher than fixture C1.

(About the guide member 30)
Next, the guide member 30 will be explained with reference to FIGS. 3 to 5. FIG. 3 is a top view of the oil level gauge tube fixing structure. FIG. 4 is a side view of the oil level gauge tube fixing structure. FIG. 5 is a diagram showing the guide member as a single unit. FIGS. 5(a), 5(b), and 5(c) are a front view, a top view, and a right side view, respectively.

In the following description, "outside" means the outside of the arc shape at a location where the oil level gauge tube 10 is bent into an arc shape, as shown in FIG. 3, and "inside" means the inside of the arc shape. In this specification, the outside of the bent portion of the oil level gauge tube 10 is referred to as the outside of the bent portion, and the inside thereof is referred to as the inside of the bent portion. Although the expression "circular arc shape" is used for convenience of explanation, the oil level gauge tube 10 does not necessarily need to extend along a precise circular arc shape.

The guide member 30 is a member that guides the bent portion of the oil level gauge tube 10. In this embodiment, the guide member 30 is formed by bending a wire rod. The cross-sectional shape of the wire may be circular, elliptical, or polygonal, but in this embodiment it is circular.

The guide member 30 has a first portion 31 and a second portion 32, as shown in FIGS. 4 and 5.

The first portion 31 is a portion that supports the oil level gauge tube 10 from the inside at the bent portion of the oil level gauge tube 10, as shown in FIG. As shown in FIG. 5, the first portion 31 has a first rod-shaped portion 31-1 and a second rod-shaped portion 31-2 that extend parallel to each other.

The second portion 32 is a portion formed to be bent from the upper portion of the first portion 31 . Specifically, the second portion 32 extends in a direction perpendicular to the direction in which the first portion 31 extends. In this example, the connecting portion between the first portion 31 and the second portion 32 is formed into a gently curved arc shape. Note that the angle between the first portion 31 and the second portion 32 is arbitrary and is not limited to 90°.

The guide member 30 is fixed to the support bracket 21 in the state shown in FIGS. 2 to 4. The guide member 30 is fixed to an inner surface (a surface opposite to the surface on which the oil level gauge tube 10 is arranged) at an inner position between the inner and outer sides of the support bracket 21. Specifically, the side surface of the first rod-shaped portion 31-1 is fixed to the surface of the first region 21a, and the side surface of the second rod-shaped portion 31-2 is fixed to the surface of the second region 21b, so that the guide member 30 is fixed to the support bracket 21.

The first rod-shaped portion 31-1 and the second rod-shaped portion 31-2 are each fixed to the support bracket 21 by, for example, welding. The first rod-shaped portion 31-1 and the second rod-shaped portion 31-2 have a circular cross-sectional shape, and this configuration in which the circular rod-shaped portion is fixed to the surface of the support bracket 21 has the following advantages. be. That is, if a rod-shaped member having a polygonal cross-sectional shape is to be fixed to the surface of the support bracket 21, the support bracket 21 and the guide member 30 should have a high shape so that one surface of the polygon faces the surface of the support bracket 21. It must be formed with precision. On the other hand, in the case of a configuration in which a circular rod-shaped portion is fixed to a predetermined surface, the guide member 30 can be fixed in various orientations, which is advantageous in that the shape accuracy required for the component can be suppressed.

As shown in FIG. 3, the second portion 32 extends outward above the oil level gauge tube 10. As shown in FIG. Specifically, the second portion 32 extends from the inside to the outside so as to cover the oil level gauge tube 10. The amount of protrusion of the second portion 32 from the first portion 31 is set to be long enough so that the tip of the second portion 32 is located outside the oil level gauge tube 10. For example, the horizontal length d1 (see FIG. 5) between the tip of the second portion 32 and the first portion 31 may be at least twice the diameter of the oil level gauge tube 10, or may be three times the diameter of the oil level gauge tube 10. It may be more than that.

(Assembly state of oil level gauge tube fixing structure S100)
The bracket assembly 20 and the guide member 30, which are in the subassembly state as shown in FIG. 2, are fixed to the plate 42 as shown in FIG. Then, the oil level gauge tube 10 is fixed to the bracket assembly 20 by the fixture C1 and the fixture C2, thereby assembling the oil level gauge tube fixing structure S100.

In this state, the bent portion of the oil level gauge tube 10 is guided by the guide member 30. According to the configuration in which the bent portion of the oil level gauge tube 10 is guided by the guide member 30 in this way, the oil level gauge tube 10 is placed at an appropriate position in the vehicle, and the oil level gauge tube 10 is prevented from interfering with other parts. It is prevented from doing so.

Further, in the present embodiment, the tip of the second portion 32 of the guide member 30 protrudes outward from the oil level gauge tube 10. According to such a configuration, even if some member or the like moves toward the oil level gauge tube fixing structure S100 from the outside (corresponding to the front of the vehicle), that member will come into contact with the second portion 32. Therefore, the guide member 30 functions as a protection member, and damage to the oil level gauge tube 10 is prevented.

As understood from FIGS. 3 and 4, the second portion 32 is positioned above the oil level gauge tube 10, thereby serving to regulate the upper limit position at which the oil level gauge tube 10 is placed. That is, because the second portion 32 is provided, the oil level gauge tube 10 does not move above the second portion 32. According to such a configuration, the upper limit position of the oil level gauge tube 10 is well defined.

Moreover, in this embodiment, as shown in FIG. It is located in space A. The upper part 21u is the upper end of the support bracket 21 here. According to the configuration in which the oil level gauge tube 10 is arranged in the space A surrounded on three sides in the side view of FIG. 4, even if some member or the like moves toward the oil level gauge tube 10, the oil level gauge tube 10 The level gauge tube 10 is less likely to be damaged. Further, since the position of the oil level gauge tube 10 in the height direction is defined by the upper portion 21u of the support bracket 21 and the second portion 32, the accuracy of positioning the oil level gauge tube 10 is also improved.

As described above, the oil level gauge tube 10 is arranged so that its height gradually increases from the proximal end to the distal end. In order to better define the position of the oil level gauge tube 10, as illustrated in FIG. In one form, it is preferable that the height of the fixing member C2 be located at a height between the height of the fixture C2.

The guide member 30 may be arranged such that the second portion 32 is diagonal along the extending direction of the oil level gauge tube 10 when the oil level gauge tube fixing structure S100 is assembled to the vehicle. In order to realize such a configuration, for example, it is also assumed that the guide member 30 is attached to the support bracket 21 of the bracket assembly 20 in an inclined direction. However, in this embodiment, the guide member 30 is attached in a direction that is not inclined with respect to the support bracket 21 (for example, in a direction in which the extending direction of the supporting bracket 21 and the extending direction of the second portion 32 are horizontal). , a structure is adopted in which the bracket assembly 20 in the state of a subassembly is attached in an inclined direction with respect to the plate 42.

(effect)
As explained above, according to the oil level gauge tube fixing structure S100 of the present embodiment, the first portion 31 and the second portion 32 of the guide member 30 hold the oil level gauge tube 10 at the bent portion of the oil level gauge tube 10. Since the position of the oil level gauge tube 10 is regulated, the oil level gauge tube 10 can be positioned at a predetermined position, and the oil level gauge tube 10 can be prevented from interfering with the components of the vehicle. Further, unlike a fixing device such as a clip, the guide member 30 does not surround and hold the oil level gauge tube 10, so even if the shape of the bent portion of the oil level gauge tube 10 differs depending on the vehicle model, the oil level The gauge tube 10 can be guided well, and thus it can be applied to various types of vehicles.

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 can be made within the scope of the gist. be. For example, all or part of the device can be functionally or physically distributed and integrated into arbitrary units. In addition, new embodiments created by arbitrary combinations of multiple embodiments are also included in the embodiments of the present invention. The effects of the new embodiment resulting from the combination have the effects of the original embodiment.
