Description

[Technical field]

[0001] The present invention relates to a horn mounting structure for a vehicle. [Background technology]

[0002] Conventionally, a horn mounting structure has been known in which a horn that emits a warning sound is mounted to the front of a vehicle body of an automobile having a front bumper and a front grille that is disposed above the front bumper and has a grill opening formed therein (see Patent Document 1).

[0003] The horn described in Patent Document 1 is disposed behind a front grille, and the horn mounting structure has a sound pressure reflection cover disposed rearward from the rear surface of the front grille towards the outer periphery of the horn. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2006-27523 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, if a cylindrical horn tube extending in the fore-and-aft direction of the vehicle is formed on a panel member located at the front of the engine compartment, the front outer periphery of the horn is covered with the horn tube, and engine accessories are located behind the horn, the flow speed of the traveling wind that penetrates between the horn tube and the horn is increased.

[0006] If foreign matter such as snow or water is carried to the auxiliary equipment by the fast-flowing wind, for example, the auxiliary equipment may freeze. For this reason, when the auxiliary equipment is provided behind the horn cylinder, it is necessary to prevent foreign matter from being carried to the auxiliary equipment.

[0007] The present invention has been made in response to the above-mentioned problems, and aims to provide a horn mounting structure that can prevent foreign objects from being carried to the accessory by the wind passing through the horn tubular portion when the horn tubular portion is positioned in front of the accessory. [Means for solving the problem]

[0008] The present invention provides a horn mounting structure for a vehicle comprising a panel member having a vertical wall and arranged in an engine room located at the front of the vehicle, a horn arranged on the panel member and outputting a warning sound, a horn tubular portion protruding forward from the vertical wall and having an opening at its front end in the protruding direction and covering at least the outer periphery of the front end of the horn, and an accessory arranged in the engine room so as to be located rearward of the horn tubular portion, wherein the horn tubular portion is formed in a truncated cone shape whose radius expands rearward from the opening. Effect of the Invention

[0009] According to the present invention described above, when the horn tubular portion is disposed in front of the auxiliary equipment, foreign matter can be prevented from being carried to the auxiliary equipment by the traveling wind passing through the horn tubular portion.

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a vehicle horn mounting structure according to the present invention will be described with reference to the drawings. 1 to 10 are diagrams showing a vehicle horn mounting structure according to one embodiment of the present invention.

[0014] 1 to 10, the up, down, front, rear, left and right directions are based on the engine when installed in a vehicle, the front to back direction of the vehicle is the front-to-rear direction, the side where the radiator is installed is the front, and the side where the engine is installed is the rear.

[0015] The left-right direction of the vehicle (vehicle width direction) is defined as the left-right direction, with the catalytic converter side defined as the left and the intake duct side defined as the right. The height direction of the engine is defined as the up-down direction, with the air cleaner side defined as the top and the side opposite the air cleaner defined as the bottom.

[0016] First, the configuration will be described. 1, a vehicle 1 is equipped with a front bumper 2, which is disposed at the front of the vehicle 1. Behind the front bumper 2, an engine room 3 is disposed.

[0017] A front grille (not shown) is opened in the front bumper 2. The front grille communicates the front of the front bumper 2 with the engine room 3, and takes in air from the front of the vehicle 1 into the engine room 3.

[0018] As shown in FIGS. 1 and 2, an upper member 4 and a bumper member 5 are disposed at the rear end of the front bumper 2, and the upper member 4 is disposed above and rearward of the bumper member 5.

[0019] 1, an engine 6 and an intake system 7 are disposed in an engine room 3. The intake system 7 includes an intake duct 8, an intake pipe 9, an air cleaner 10, and an intake pipe 11.

[0020] As shown in Fig. 2, the intake duct 8 is fixed to the upper member 4. The intake duct 8 has an intake port 8a opened at the front end (see Fig. 2), and takes in air taken into the engine compartment 3 from the front grille through the intake port 8a.

[0021] As shown in FIG. 1, the intake pipe 9 extends rearward from the intake duct 8 and connects the intake duct 8 to an air cleaner 10 .

[0022] The air cleaner 10 is disposed on top of the engine 6 and purifies the air taken in from the intake duct 8 to the intake pipe 9 .

[0023] The intake pipe 11 sends the air purified by the air cleaner 10 to an intake port (not shown) of the engine 6 via an intake manifold (not shown) provided in the engine 6 .

[0024] A catalytic converter 12 is provided in front of the engine 6, and exhaust gas burned in a combustion chamber (not shown) of the engine 6 is discharged from an exhaust port (not shown) of the engine 6 to the catalytic converter 12 and purified by the catalytic converter 12.

[0025] A radiator 21 is provided in the engine room 3, and the radiator 21 is disposed below the upper member 4 and in front of the engine 6.

[0026] A lower member (not shown) is provided below the bumper member 5, and the radiator 21 is fixed to the upper member 4 and the lower member so as to be sandwiched between the upper member 4 and the lower member in the vertical direction.

[0027] The radiator 21 includes a radiator body 22 (see FIG. 2) and a fan shroud 23.

[0028] The radiator body 22 is configured by alternately stacking flat water tubes (not shown), and cools the cooling water by exchanging heat between the cooling water flowing through the water tubes and outside air.

[0029] The fan shroud 23 is attached to the rear of the radiator body 22. The fan shroud 23 has a cooling fan (not shown) and a fan motor (not shown) that rotates and drives the cooling fan.

[0030] The fan shroud 23 draws air taken into the engine compartment 3 from the front of the vehicle 1 through the front grille by the rotating cooling fan into the radiator body 22. The air that has exchanged heat with the cooling water flowing through the radiator body 22 is exhausted rearward by the cooling fan.

[0031] In addition, a guide portion 23A is provided on the fan shroud 23. The guide portion 23A opens toward the catalytic converter 12 and the auxiliary machinery 13, and a portion of the air exhausted rearward by the cooling fan is directed by the guide portion 23A toward the catalytic converter 12 and the auxiliary machinery 13. The auxiliary machinery 13 is formed of, for example, a generator.

[0032] As shown in FIG. 2, a panel member 25 is provided between the upper member 4 and the bumper member 5 in the vertical direction, and the panel member 25 is fixed to the upper member 4 by brackets 28A (see FIG. 1) provided at both ends in the vehicle width direction and bracket 28B (see FIG. 2) provided in the center in the vehicle width direction.

[0033] An air vent 25a is formed in the center of the panel member 25 in the vehicle width direction, and the air vent 25a passes the air taken into the engine compartment 3 to the radiator main body.

[0034] 2, a lower vertical wall 25A is formed on the front surface of the panel member 25, and the lower vertical wall 25A extends in the vertical direction. A horn 26 that outputs a warning sound is disposed on the panel member 25, and the horn 26 is fixed to the bumper member 5 by a bracket 24 that extends in the vertical direction (see FIG. 5).

[0035] As shown in Figures 3 and 5, the lower vertical wall 25A is formed with a horn tubular portion 25B, which protrudes forward from the lower vertical wall 25A. An opening 25h is formed at the front end of the horn tubular portion 25B in the protruding direction, and the horn 26 is located rearward of the opening 25h. This allows the horn 26 to emit a warning sound forward from the opening 25h. The lower vertical wall 25A of this embodiment constitutes a vertical wall.

[0036] Horn cylinder portion 25B covers the outer periphery of the front end of horn 26, and the inner periphery diameter of opening 25h is formed to be approximately the same as or smaller than the maximum outer diameter of horn 26. This makes it possible to prevent horn 26 from being taken out of panel member 25 through opening 25h, and therefore makes it possible to prevent theft of horn 26.

[0037] 5, horn cylinder 25B is formed in a truncated cone shape whose radius increases rearward from opening 25h. In other words, horn cylinder 25B is inclined so that its radius increases rearward from opening 25h.

[0038] Specifically, the horn cylinder portion 25B has an upper base formed with an opening 25h in the front-rear direction, a lower base on the lower vertical wall 25A side, and a truncated cone surface 25b connecting the upper base and the lower base.

[0039] The accessory 13 is disposed in the engine room 3 so as to be located behind the horn cylindrical portion 25B, and at least a portion of the accessory 13 is disposed at the same height as the horn cylindrical portion 25B.

[0040] Horn 26 includes horn body 26A and diaphragm 26B provided on the front side of horn body 26A, and generates a warning sound by vibration of diaphragm 26B. Horn cylinder portion 25B covers the outer periphery of diaphragm 26B.

[0041] 5, horn body side inclined surface 26a is formed on the outer periphery of the front end of diaphragm 26B, and the radius of horn body side inclined surface 26a increases from the front side to the rear side in the front-to-rear direction. Horn body side inclined surface 26a constitutes the front end outer periphery of horn 26.

[0042] Behind horn body-side inclined surface 26a, peripheral wall 26b of horn body 26A extends parallel to the front-rear direction, with the front end of peripheral wall 26b positioned on an extension line of horn body-side inclined surface 26a.

[0043] The rear end of the horn cylindrical portion 25B is connected to an inclined portion 25C. The inclined portion 25C is located above the horn 26 and inclined obliquely upward and rearward from the upper side of the rear end of the horn cylindrical portion 25B.

[0044] The inclined portion 25C is composed of a first inclined portion 25D located at the front side in the front-to-rear direction and a second inclined portion 25E connected to the rear side of the first inclined portion 25D, and the length of the second inclined portion 25E in the front-to-rear direction is longer than the length of the first inclined portion 25D in the front-to-rear direction.

[0045] The first inclined portion 25D extends at the same inclination angle as the inclination angle θ1 of the truncated cone surface 25b with respect to the central axis O of the horn cylindrical portion 25B.

[0046] An inclination angle θ2 of the second inclined portion 25E relative to the central axis O of the horn cylindrical portion 25B is smaller than an inclination angle θ1 of the first inclined portion 25D relative to the central axis O of the horn cylindrical portion 25B.

[0047] As shown in FIGS. 2 and 3, the panel member 25 is formed with a first introduction passage portion 25F and a second introduction passage portion 25G.

[0048] The first introduction passage portion 25F is disposed above the first inclined portion 25D and the second inclined portion 25E. The second introduction passage portion 25G is located on the opposite side of the first introduction passage portion 25F with respect to the vent hole 25a, and is disposed side by side with the first introduction passage portion 25F in the vehicle width direction.

[0049] The first introduction passage portion 25F has a bottom wall 25c formed by the rear portion of the second inclined portion 25E, a left side wall 25d, a right side wall 25e, and an upper wall 25f (see FIGS. 4 and 5).

[0050] The left side wall 25d extends rearward from the lower vertical wall 25A and extends upward from the left end of the bottom wall 25c. The right side wall 25e extends rearward from the lower vertical wall 25A and extends upward from the right end of the bottom wall 25c.

[0051] The upper vertical wall 25H is connected to the rear end of the left side wall 25d and the rear end of the right side wall 25e, and is located rearward of and above the lower vertical wall 25A. The upper vertical wall 25H extends upward from the upper part of the rear end of the left side wall 25d and the upper part of the rear end of the right side wall 25e toward the intake duct 8 (see FIG. 2).

[0052] The right side wall 25e is provided with an inclined wall 25g. The inclined wall 25g is inclined from the rear end of the right side wall 25e toward the left side wall 25d.

[0053] Foreign matter contained in the air (see air A1 in FIG. 3) flowing from the front grill to the engine room 3 is introduced from the first introduction passage 25F into the engine room 3 behind the radiator 21. This air A1 is directed to the left side of the lower vertical wall 25A by the inclined wall 25g. Here, the foreign matter is, for example, water, snow, dust, etc.

[0054] Furthermore, air not containing foreign matter flowing above the first introduction passage portion 25F (see air A2 in FIG. 3) is introduced from the upper vertical wall 25H into the intake duct 8. The first introduction passage portion 25F of the present embodiment constitutes an introduction passage portion.

[0055] As shown in Figures 3 and 4, the second introduction passage portion 25G has a left side wall 25i adjacent to the right side wall 25e of the first introduction passage portion 25F in the vehicle width direction, and a right side wall 25j facing the left side wall 25i in the vehicle width direction.

[0056] The second introduction passage portion 25G has a bottom wall 25k connecting the lower end of the left side wall 25i to the lower end of the right side wall 25j, and an upper wall 25m connecting the upper end of the left side wall 25i to the upper end of the right side wall 25j.

[0057] The second introduction passage portion 25G has a rear wall 25n which is connected to the rear end of the left side wall 25i, the rear end of the right side wall 25j, the rear end of the bottom wall 25k, and the rear end of the top wall 25m.

[0058] An opening 25p is formed in the rear wall 25n, and a cylindrical portion 25q is provided in the rear wall 25n so as to surround the opening 25p and extend rearward from the rear wall 25n.

[0059] The second introduction passage portion 25G introduces foreign matter contained in the air flowing from the front grill to the engine compartment 3 (see air A3 in FIG. 3) into the engine compartment 3 behind the radiator 21.

[0060] In this way, the first introduction passage 25F introduces air A1 into the engine room 3 on the left side of the lower vertical wall 25A by the inclined wall 25g, and the second introduction passage 25G introduces air A3 into the engine room 3 behind the second introduction passage 25G. This allows foreign matter to be dispersed within the engine room 3.

[0061] Next, the effects of the horn mounting structure for the vehicle 1 according to this embodiment will be described. For comparison with the horn mounting structure of this embodiment, if a cylindrical horn tubular portion 31 (see dashed double-dashed lines in Figures 5 and 6) extending in the fore-and-aft direction is formed on the panel member 25, the flow speed of the traveling wind that penetrates between the horn tubular portion 31 and the horn 26 is increased (see air A5 in Figures 9 and 10), and the directionality toward the auxiliary equipment 13 is strengthened.

[0062] As a result, foreign matter such as snow and water can easily be carried to the auxiliary machinery 13 by the fast-flowing wind caused by running, and there is a risk that the auxiliary machinery 13 may freeze, for example.

[0063] The horn mounting structure of the vehicle 1 in this embodiment has a lower vertical wall 25A and a panel member 25 that is arranged in the engine room 3 located at the front of the vehicle 1, and a horn 26 that is arranged on the panel member 25 and outputs a warning sound.

[0064] In addition, the horn mounting structure of vehicle 1 includes a horn tubular portion 25B that protrudes forward from lower vertical wall 25A and has an opening 25h at the front end in the protruding direction, covering the horn body side inclined surface 26a (the front end outer periphery of horn 26) of vibration plate 26B, and an accessory 13 that is arranged in engine room 3 so as to be located rearward of horn tubular portion 25B, and horn tubular portion 25B is formed in a truncated cone shape whose radius expands rearward from opening 25h.

[0065] As a result, when the vehicle 1 is traveling, air that has entered the inside of the horn tubular portion 25B can be diffused outward along the truncated cone surface 25b of the horn tubular portion 25B, thereby reducing the air flow speed.

[0066] Therefore, the air introduced into the engine room 3 from the opening 25h is less likely to flow toward the auxiliary machinery 13, and foreign matter can be prevented from being carried to the auxiliary machinery 13 by the air.

[0067] In this manner, the horn mounting structure for the vehicle 1 of this embodiment can prevent foreign objects from being carried to the auxiliary device 13 by air passing through the horn cylindrical portion 25B when the horn cylindrical portion 25B is disposed in front of the auxiliary device 13. As a result, the auxiliary device 13 can be protected from foreign objects.

[0068] Figures 7 and 8 show the flow of the traveling wind that has entered between the horn tubular portion 25B and the horn 26 in this embodiment, and it can be seen that the traveling wind that has entered between the horn tubular portion 25B and the horn 26 is diffused by the horn tubular portion 25B and the inclined portion 25C, weakening its directionality toward the auxiliary equipment 13 (see air A4).

[0069] In addition, in Figures 7 to 10, air A4 and A5 are schematic diagrams showing that, of the air flowing through the engine room 3, the air flowing between the horn tube portion 31 and the horn 26 has weaker directionality toward the auxiliary equipment 13.

[0070] Furthermore, according to the horn mounting structure of vehicle 1 of this embodiment, a horn body side inclined surface 26a is formed on the outer periphery of diaphragm 26B, the radius of which increases from the front to the rear in the fore-and-aft direction, and horn tubular portion 25B has a truncated cone surface 25b inclined parallel to horn body side inclined surface 26a.

[0071] This ensures that the air flowing outward along the horn body side inclined surface 26a is guided radially outward of the horn body 26A and diffused, thereby more effectively reducing the air flow speed (see air A4 in Figure 7).

[0072] This makes it difficult for the air introduced into the engine room 3 from the opening 25h to flow toward the auxiliary machinery 13, and more effectively prevents foreign matter from being carried to the auxiliary machinery 13 by the air.

[0073] Furthermore, according to the horn mounting structure of the vehicle 1 of this embodiment, the rear end of the horn tubular portion 25B is connected to an inclined portion 25C which is located above the horn 26 and inclines upward and rearward from the upper rear side of the horn tubular portion 25B, and the inclined portion 25C is configured to include a first inclined portion 25D located on the front side and a second inclined portion 25E which is connected to the rear side of the first inclined portion 25D.

[0074] The first inclined portion 25D extends at the same inclination angle θ1 as the inclination angle θ1 of the truncated cone surface 25b relative to the central axis O of the horn cylindrical portion 25B, and the inclination angle θ2 of the second inclined portion 25E relative to the central axis O of the horn cylindrical portion 25B is formed to be smaller than the inclination angle θ1 of the first inclined portion 25D relative to the central axis O of the horn cylindrical portion 25B.

[0075] This enables the air flowing between the first inclined portion 25D and the second inclined portion 25E and the horn 26 to be reliably guided radially outward of the horn main body 26A and diffused, thereby more effectively reducing the air flow speed.

[0076] This makes it difficult for the air introduced into the engine room 3 from the opening 25h to flow toward the auxiliary machinery 13, and more effectively prevents foreign matter from being carried to the auxiliary machinery 13 by the air.

[0077] Furthermore, by forming the inclination angle θ2 of the second inclined portion 25E relative to the central axis O of the horn cylindrical portion 25B to be smaller than the inclination angle θ1 of the first inclined portion 25D relative to the central axis O of the horn cylindrical portion 25B, it is possible to prevent the radius of the second inclined portion 25E from becoming too large.

[0078] As a result, the vertical dimension of the panel member 25 having the horn tubular portion 25B, the first inclined portion 25D and the second inclined portion 25E can be reduced, and the panel member 25 can be efficiently arranged in the small space at the front of the engine compartment 3.

[0079] Furthermore, according to the horn mounting structure of the vehicle 1 of this embodiment, the panel member 25 has a first inlet passage portion 25F that introduces air into the engine room 3, and the first inlet passage portion 25F is arranged above the first inclined portion 25D and the second inclined portion 25E.

[0080] This allows the first introduction passage portion 25F to be disposed using the space above the second inclined portion 25E, and allows the second inclined portion 25E to be used as the bottom wall 25c of the first introduction passage portion 25F.

[0081] Although an embodiment of the invention has been disclosed, it will be apparent to one skilled in the art that modifications may be made without departing from the spirit and scope of the invention, and all such modifications and equivalents are intended to be encompassed by the following claims.
