Abstract

PROBLEM TO BE SOLVED: To downsize electric horns while restraining invasion of foreign matter through openings of sound wave outlets.SOLUTION: By disposing on an inner wall face near a sound wave outlet opening 202 in a resonance tube 20 a wind shield wall 203 that slows down the flow speed of running winds W invading from the sound wave outlet opening 202 into a sound passage 201, the running winds W are prevented from readily invading deep into the sound passage 201 to make it possible to restrain invasion of foreign matter. Also, as the wind shield wall 203 is arranged within the resonance tube 20, the electric horn can be reduced in size.

Description

本発明は、乗用車、バス、トラック等の車両に取り付けられる車両用電気式ホーンに関するものである。   The present invention relates to a vehicular electric horn attached to a vehicle such as a passenger car, a bus, or a truck.

従来の車両用電気式ホーンは、電磁力により振動する振動部材により空気を振動させて疎密波(音波)を作り、共鳴管により増幅させて音波出口開口部から出射する。そして、音波出口開口部からの水、雪、砂等の異物の侵入を抑制するため、音波出口開口部を覆うようにして異物進入防止部材を共鳴管に装着している(例えば、特許文献1参照)。   In a conventional electric horn for a vehicle, air is vibrated by a vibrating member that vibrates due to electromagnetic force to generate a dense wave (sound wave), which is amplified by a resonance tube and emitted from a sound wave outlet opening. In order to suppress entry of foreign matter such as water, snow, and sand from the sound wave outlet opening, a foreign matter intrusion prevention member is attached to the resonance tube so as to cover the sound wave outlet opening (for example, Patent Document 1). reference).

特開2011−76018号公報JP 2011-76018 A

しかしながら、異物進入防止部材が共鳴管の外部に配置されるため、電気式ホーンが大型化してしまうという問題があった。   However, since the foreign matter intrusion preventing member is arranged outside the resonance tube, there is a problem that the electric horn is increased in size.

本発明は上記点に鑑みて、音波出口開口部からの異物の侵入を抑制しつつ、電気式ホーンの小型化を図ることを目的とする。   In view of the above points, an object of the present invention is to reduce the size of an electric horn while suppressing entry of foreign matter from a sound wave outlet opening.

上記目的を達成するため、請求項1に記載の発明では、ホーンハウジング(10)と、ホーンハウジングに固定され、音波を発生する振動部材(11)と、ホーンハウジングに接続され、音道(201、208)が内部に形成されて振動部材から発生される音波を共鳴させる共鳴管(20)とを備える車両用電気式ホーンであって、共鳴管における音波出口開口部(202、209)近傍の内壁面に、音波出口開口部から音道に侵入する走行風の流速を低下させる防風壁(203)を備えることを特徴とする。   In order to achieve the above object, according to the first aspect of the present invention, the horn housing (10), the vibration member (11) that is fixed to the horn housing and generates sound waves, is connected to the horn housing, and the sound path (201 208) is formed in the interior and includes a resonance tube (20) for resonating a sound wave generated from the vibration member, in the vicinity of the sound wave outlet opening (202, 209) in the resonance tube. The inner wall surface is provided with a windbreak wall (203) for reducing the flow velocity of the traveling wind entering the sound path from the sound wave outlet opening.

これによると、音道に侵入する走行風の流速を低下させるため、走行風が音道の奥まで侵入し難くなり、異物の侵入を抑制することができる。また、防風壁は共鳴管の内部に配置されるため、電気式ホーンの小型化を図ることができる。   According to this, since the flow velocity of the traveling wind that enters the sound path is reduced, the traveling wind does not easily enter the depths of the sound path, and foreign objects can be prevented from entering. Moreover, since the windbreak wall is disposed inside the resonance tube, the electric horn can be reduced in size.

(First embodiment)
A first embodiment of the present invention will be described. In addition, the top and bottom arrows in the figure indicate the top and bottom direction when mounted on the vehicle, and the front and rear arrows indicate the front and rear direction of the vehicle when mounted on the vehicle.

図1に示すように、段付き円筒状のホーンハウジング10には、ホーンハウジング10の一端側開口部を覆うようにして、音波を発生する薄板状の振動部材11が固定されるとともに、さらに振動部材11を覆うようにして、板状のカバー部材12が固定されている。このカバー部材12の中心部には、開口部120が設けられている。そして、このカバー部材12の外周端部が、振動部材11の外周端部の上から重なるようにして、ホーンハウジング10の外周端部に巻締め固定されている。   As shown in FIG. 1, a stepped cylindrical horn housing 10 is fixed with a thin plate-like vibrating member 11 that generates a sound wave so as to cover an opening at one end of the horn housing 10, and further vibrates. A plate-like cover member 12 is fixed so as to cover the member 11. An opening 120 is provided at the center of the cover member 12. Then, the outer peripheral end portion of the cover member 12 is wound and fixed to the outer peripheral end portion of the horn housing 10 so as to overlap the outer peripheral end portion of the vibration member 11.

ホーンハウジング10内には、電磁力により振動部材11を振動させるための、円筒状のコイル13、円柱状の固定鉄心14、および円柱状の可動鉄心15が配置されている。コイル13および固定鉄心14は、ホーンハウジング10に固定されている。可動鉄心15は、振動部材11の中央部にカシメ固定されている。   In the horn housing 10, a cylindrical coil 13, a columnar fixed iron core 14, and a columnar movable iron core 15 are arranged for vibrating the vibrating member 11 by electromagnetic force. The coil 13 and the fixed iron core 14 are fixed to the horn housing 10. The movable iron core 15 is caulked and fixed to the central portion of the vibration member 11.

ホーンハウジング10内には、コイル13への通電回路を開閉するための、可動接点16および固定接点17が配置されている。可動接点16は、バネ板18に固定されていて、バネ板18のバネ力により固定接点17側に向かって付勢されている。   In the horn housing 10, a movable contact 16 and a fixed contact 17 for opening and closing an energization circuit to the coil 13 are arranged. The movable contact 16 is fixed to the spring plate 18 and is biased toward the fixed contact 17 side by the spring force of the spring plate 18.

バネ板18の先端側は可動鉄心15に対向しており、可動鉄心15が固定鉄心14側に吸引されると、可動鉄心15によりバネ板18の先端側が固定鉄心14側に移動され、可動接点16が固定接点17から離れてコイル13への通電回路が開かれる。   The distal end side of the spring plate 18 faces the movable iron core 15, and when the movable iron core 15 is attracted to the fixed iron core 14 side, the movable iron core 15 moves the distal end side of the spring plate 18 to the fixed iron core 14 side, and the movable contact point. 16 leaves the fixed contact 17 and the energization circuit to the coil 13 is opened.

また、通電回路が開かれて電磁力が消滅すると、可動鉄心15が固定鉄心14から遠ざかる向きに移動し、可動接点16が固定接点17に当接してコイル13への通電回路が閉じられるようになっている。   When the energization circuit is opened and the electromagnetic force disappears, the movable iron core 15 moves away from the fixed iron core 14 so that the movable contact 16 contacts the fixed contact 17 and the energization circuit to the coil 13 is closed. It has become.

ホーンハウジング10には、カバー部材12を覆うようにして、樹脂製の共鳴管20が固定されている。   A resin resonance tube 20 is fixed to the horn housing 10 so as to cover the cover member 12.

図1、図2に示すように、共鳴管20の中心部には、振動部材11から発生された音波の入口となる音波入口開口部200が形成されている。共鳴管20の内部には、この音波入口開口部200から伝えられる音波を増幅させながら伝搬する渦巻き状の音道201が形成されている。共鳴管20の外縁部には、この音道201を通過した音波を外部に出射する音波出口開口部202が形成されている。   As shown in FIGS. 1 and 2, a sound wave inlet opening 200 serving as an inlet for sound waves generated from the vibrating member 11 is formed at the center of the resonance tube 20. A spiral sound path 201 that propagates while amplifying the sound wave transmitted from the sound wave inlet opening 200 is formed inside the resonance tube 20. A sound wave outlet opening 202 for emitting the sound wave that has passed through the sound path 201 to the outside is formed at the outer edge of the resonance tube 20.

ここで、本実施形態の電気式ホーンは、図2に示すように、車両前後方向(図2の紙面垂直方向)に見たときに音道201が渦巻き状に見えるようにして、車両に装着される。また、本実施形態の電気式ホーンは、音波出口開口部202が下方に位置するようにして、車両に装着される。   Here, as shown in FIG. 2, the electric horn of the present embodiment is mounted on the vehicle so that the sound path 201 looks spiral when viewed in the vehicle front-rear direction (vertical direction in FIG. 2). Is done. In addition, the electric horn of the present embodiment is mounted on the vehicle such that the sound wave outlet opening 202 is positioned below.

図1、図3、図4に示すように、音道201を形成する内壁面には、音波出口開口部202近傍で且つ車両後方側の部位に、音波出口開口部202から音道201に侵入する走行風Wの流速を低下させる防風壁203が一体に形成されている。   As shown in FIGS. 1, 3, and 4, the inner wall surface forming the sound path 201 enters the sound path 201 from the sound wave outlet opening 202 in the vicinity of the sound wave outlet opening 202 and on the rear side of the vehicle. A windbreak wall 203 that reduces the flow velocity of the traveling wind W is formed integrally.

この防風壁203は、板状であり、車両左右方向(図3の紙面上下方向)に延びるとともに、音道201を形成する内壁面から音道201側に向かって突出している。また、この防風壁203は、音道201のうち天地方向最上部(以下、音道頂点という)と音波出口開口部202との間に配置されている。   The windbreak wall 203 has a plate shape, extends in the left-right direction of the vehicle (the vertical direction in FIG. 3), and protrudes from the inner wall surface forming the sound path 201 toward the sound path 201 side. Further, the windbreak wall 203 is disposed between the top in the top-and-bottom direction (hereinafter referred to as the sound path apex) of the sound path 201 and the sound wave outlet opening 202.

次に、上記構成になる電気式ホーンの作動を説明する。電気式ホーンは、コイル13への通電を断続させることで、可動鉄心15が固定鉄心14に断続的に吸引されて振動する。可動鉄心15が振動すると、振動部材11も一緒に振動し、振動部材11が音波を発生する。その音波は、音波入口開口部200から音道201に入射し、音道201を通って音波出口開口部202に至り、音波出口開口部202から外部に警報音として出射される。   Next, the operation of the electric horn configured as described above will be described. The electric horn vibrates by intermittently attracting the movable iron core 15 to the fixed iron core 14 by intermittently energizing the coil 13. When the movable iron core 15 vibrates, the vibration member 11 also vibrates together, and the vibration member 11 generates sound waves. The sound wave enters the sound path 201 from the sound wave entrance opening 200, reaches the sound wave exit opening 202 through the sound path 201, and is emitted from the sound wave exit opening 202 to the outside as an alarm sound.

ところで、車両走行中には、走行風Wが音波出口開口部202から音道201に侵入する。その走行風Wは、音波出口開口部202近傍の内壁面のうち車両後方側の内壁面に沿って流れるが、防風壁203が抵抗になって流速が低下させられる。したがって、走行風Wが音道201の奥まで侵入し難くなり、走行風Wとともに異物が侵入するのを抑制することができる。   By the way, during traveling of the vehicle, the traveling wind W enters the sound path 201 from the sound wave outlet opening 202. The traveling wind W flows along the inner wall surface on the vehicle rear side of the inner wall surface in the vicinity of the sound wave outlet opening 202, but the windbreak wall 203 becomes a resistance and the flow velocity is reduced. Therefore, it becomes difficult for the traveling wind W to enter the depth of the sound path 201, and foreign objects can be prevented from entering with the traveling wind W.

なお、走行風Wが音道頂点まで到達しなければ、水、雪、砂等の異物も音道頂点を越えない。したがって、走行風Wが音道頂点まで到達しない速度まで走行風Wの流速が低下するように、防風壁203の仕様を設定する。   If the traveling wind W does not reach the top of the sound path, foreign matter such as water, snow, and sand does not exceed the top of the sound path. Therefore, the specification of the windbreak wall 203 is set so that the flow velocity of the traveling wind W decreases to a speed at which the traveling wind W does not reach the top of the sound path.

また、防風壁203は共鳴管20の内部に配置されるため、電気式ホーンの小型化を図ることができる。   Further, since the windbreak wall 203 is disposed inside the resonance tube 20, the electric horn can be reduced in size.

さらに、防風壁203は共鳴管20に一体に形成されるため、従来の異物進入防止部材のような別部品を設ける必要がない。   Further, since the windbreak wall 203 is formed integrally with the resonance tube 20, it is not necessary to provide another component such as a conventional foreign matter entry preventing member.

(第2実施形態)
本発明の第2実施形態について説明する。なお、図中の天地の矢印は車両に装着したときの天地方向を示し、前後の矢印は車両に装着したときの車両の前後方向を示している。
(Second Embodiment)
A second embodiment of the present invention will be described. In addition, the top and bottom arrows in the figure indicate the top and bottom direction when mounted on the vehicle, and the front and rear arrows indicate the front and rear direction of the vehicle when mounted on the vehicle.

本実施形態は、共鳴管20の構成が第1実施形態と異なり、その他に関しては第1実施形態と同様であるため、異なる部分についてのみ説明する。   In the present embodiment, the configuration of the resonance tube 20 is different from that of the first embodiment, and the other parts are the same as those of the first embodiment. Therefore, only different portions will be described.

図5〜図8に示すように、共鳴管20における車両前方側の壁面は、ホーンハウジング10(図1参照)側の端面204と平行な平行壁面205と、ホーンハウジング10側の端面204に対して傾斜した傾斜壁面206とからなり、共鳴管20における車両前方側の面は段付き状になっている。また、平行壁面205と傾斜壁面206との間には、ホーンハウジング10側の端面204に対して垂直で且つ天地方向に延びる直交壁面207が形成されている。   As shown in FIGS. 5 to 8, the wall surface of the resonance tube 20 on the vehicle front side is parallel to the parallel wall surface 205 parallel to the end surface 204 on the horn housing 10 (see FIG. 1) side and the end surface 204 on the horn housing 10 side. The surface of the resonance tube 20 on the vehicle front side is stepped. Further, between the parallel wall surface 205 and the inclined wall surface 206, an orthogonal wall surface 207 extending perpendicularly to the end surface 204 on the horn housing 10 side and extending in the vertical direction is formed.

共鳴管20は、音波出口開口部202に近い位置で音道201から分岐された分岐音道208を備えている。そして、直交壁面207に、分岐音道208を通過した音波を外部に出射する第2音波出口開口部209が形成されている。なお、音波出口開口部202と第2音波出口開口部209は、異なる方向に向かって音波を出射する。   The resonance tube 20 includes a branched sound path 208 branched from the sound path 201 at a position close to the sound wave outlet opening 202. A second sound wave outlet opening 209 that emits sound waves that have passed through the branch sound path 208 to the outside is formed in the orthogonal wall surface 207. The sound wave outlet opening 202 and the second sound wave outlet opening 209 emit sound waves in different directions.

分岐音道208を形成する内壁面には、第2音波出口開口部209から分岐音道208に侵入する走行風Wの流速を低下させる防風壁203が一体に形成されている。この防風壁203は、板状であり、天地方向に延びるとともに、分岐音道208を形成する内壁面から分岐音道208側に向かって突出している。また、この防風壁203は、音道201のうち天地方向最上部と第2音波出口開口部209との間に配置されている。   On the inner wall surface forming the branched sound path 208, a windbreak wall 203 that reduces the flow velocity of the traveling wind W that enters the branched sound path 208 from the second sound wave outlet opening 209 is integrally formed. The windbreak wall 203 has a plate shape, extends in the vertical direction, and protrudes from the inner wall surface forming the branched sound path 208 toward the branched sound path 208 side. Further, the windbreak wall 203 is disposed between the top in the vertical direction of the sound path 201 and the second sound wave outlet opening 209.

上記構成において、振動部材11が発生した音波は、音道201を通って音波出口開口部202に至り、音波出口開口部202から外部に警報音として出射されるとともに、音道201および分岐音道208を通って第2音波出口開口部209に至り、第2音波出口開口部209から外部に警報音として出射される。   In the above configuration, the sound wave generated by the vibrating member 11 passes through the sound path 201 to the sound wave outlet opening 202 and is emitted from the sound wave outlet opening 202 to the outside as an alarm sound. The second sound wave outlet opening 209 is passed through 208 and emitted from the second sound wave outlet opening 209 to the outside as an alarm sound.

ところで、平行壁面205に衝突した走行風Wは、向きを変えて第2音波出口開口部209から分岐音道208に侵入した後、一部が音道201側に流れる。ここで、第2音波出口開口部209から分岐音道208に侵入した走行風Wは、防風壁203が抵抗になって流速が低下させられる。したがって、分岐音道208から音道201側に流れる走行風Wは音道201の奥まで侵入し難くなり、走行風Wとともに異物が侵入するのを抑制することができる。   By the way, after the traveling wind W colliding with the parallel wall surface 205 changes its direction and enters the branch sound path 208 from the second sound wave outlet opening 209, a part of the traveling wind W flows to the sound path 201 side. Here, the traveling wind W that has entered the branch sound path 208 from the second sound wave outlet opening 209 is reduced in flow velocity by the windbreak wall 203 acting as a resistance. Therefore, the traveling wind W flowing from the branching sound path 208 toward the sound path 201 becomes difficult to penetrate to the back of the sound path 201, and foreign matter can be prevented from entering with the traveling wind W.

なお、上記各実施形態は、実施可能な範囲で任意に組み合わせが可能である。   In addition, each said embodiment can be arbitrarily combined in the range which can be implemented.
