Abstract

To suppress wind noise caused by a mall.SOLUTION: An electric vehicle comprises: a vehicle body; a mall which is attached to a front part of the vehicle; and a lip member which is swingably supported between an open position and a closing position at a gap between a front edge of the mall and the vehicle body. At the time of the open position of the lip member, the front edge of the lip member is alienated from the vehicle body to form a gap between the lip member and the vehicle body. At the time of the closing position of the lip member, the front edge of the lip member contacts with the vehicle body to block the gap between the lip member and the vehicle body. While the lip member is energized into the open position, the lip member moves to the closing position when receiving wind pressure in accompany with traveling of the electric vehicle.SELECTED DRAWING: Figure 2

モールと車体との間には、組み付け時の干渉を避けるために、一定の隙間を設ける必要がある。しかしながら、モールと車体との間に隙間が存在すると、車両の走行時に風切り音が発生する。このような風切り音は、エンジンが存在しない電動車において、新たな問題となっている。特に、モールが車体の前部に位置する場合は、風切り音が発生しやすいとともに、車内のユーザによって認知されやすい。本明細書は、このような問題を解決し得る技術を提供する。 A certain gap must be provided between the molding and the vehicle body to avoid interference during assembly. However, if a gap exists between the molding and the vehicle body, wind noise will occur when the vehicle is running. Such wind noise has become a new problem in electric vehicles that do not have engines. In particular, when the molding is located at the front of the vehicle body, wind noise is likely to be generated and easily perceived by users inside the vehicle. This specification provides a technique that can solve such problems.

本明細書が開示する技術は、電動車に具現化される。この電動車は、車体と、車体の前部に取り付けられたモールと、モールの前縁と車体との間の隙間において、開放位置と閉塞位置との間を揺動可能に支持されたリップ部材とを備える。リップ部材が開放位置にあるときは、リップ部材の前端が車体から離間して、リップ部材と車体との間に隙間が形成される。リップ部材が閉塞位置にあるときは、リップ部材の前端が車体に接触して、リップ部材と車体との間の隙間が閉塞される。リップ部材は、開放位置に向けて付勢されているとともに、電動車の走行に伴う風圧を受けて閉塞位置へ移動するように構成されている。 The technology disclosed in this specification is embodied in an electric vehicle. This electric vehicle includes a vehicle body, a molding attached to the front of the vehicle body, and a lip member supported in a gap between the front edge of the molding and the vehicle body to be able to swing between an open position and a closed position. Equipped with. When the lip member is in the open position, the front end of the lip member is separated from the vehicle body, and a gap is formed between the lip member and the vehicle body. When the lip member is in the closed position, the front end of the lip member contacts the vehicle body, and the gap between the lip member and the vehicle body is closed. The lip member is biased toward the open position and is configured to move to the closed position in response to wind pressure as the electric vehicle travels.

上記した構成によると、電動車が走行しているときは、モールの前縁と車体との間の隙間が、リップ部材によって少なくとも部分的に閉塞される。これにより、当該隙間に起因する風切り音の発生が抑制される。一方、電動車が停止しているときは、リップ部材が車体から離間することで、組み付け時に必要とされる隙間や、雨水等を排水するための隙間を確保することができる。 According to the above configuration, when the electric vehicle is running, the gap between the front edge of the molding and the vehicle body is at least partially closed by the lip member. This suppresses the generation of wind noise caused by the gap. On the other hand, when the electric vehicle is stopped, the lip member is separated from the vehicle body, thereby ensuring a gap required during assembly and a gap for draining rainwater and the like.

実施例の電動車10の要部を示す平面図。なお、フード16の一部は破断されており、フード16の下方に位置するモール20が図示されている。FIG. 1 is a plan view showing main parts of an electric vehicle 10 according to an embodiment. Note that a part of the hood 16 is cut away, and the molding 20 located below the hood 16 is illustrated. 図1中のII-II線における断面図。FIG. 2 is a cross-sectional view taken along line II-II in FIG. 1. 図2中のIII-III線における断面図。3 is a sectional view taken along line III-III in FIG. 2. FIG.

図面を参照して、実施例の電動車10について説明する。図1に示すように、電動車10は、車体12と、車体12の前部12fに取り付けられたモール20を備える。モール20は、例えばクリップ(プッシュリベットとも称される)を用いて、車体に取り付けられている。車体12は、電動車10の外板部材であって、金属材料で構成されている。モール20は、準外板部品であって、樹脂材料で構成されている。特に限定されないが、モール20は、フェンダー14上に位置しており、フード16によって覆われている。 An electric vehicle 10 according to an embodiment will be described with reference to the drawings. As shown in FIG. 1, the electric vehicle 10 includes a vehicle body 12 and a molding 20 attached to a front portion 12f of the vehicle body 12. The molding 20 is attached to the vehicle body using, for example, a clip (also called a push rivet). The vehicle body 12 is an outer plate member of the electric vehicle 10, and is made of a metal material. The molding 20 is a semi-outer panel component and is made of a resin material. Although not particularly limited, the molding 20 is located on the fender 14 and covered by the hood 16.

図2に示すように、電動車10は、リップ部材30をさらに備える。リップ部材30は、モール20の前縁20aと車体12との間の隙間に配置されている。リップ部材30は、シャフト32によって支持されており、開放位置(図2中の破線で示す位置)と、閉塞位置(図2中の実線で示す位置)との間を、揺動可能に構成されている。特に限定されないが、リップ部材30は樹脂材料で構成されている。 As shown in FIG. 2, the electric vehicle 10 further includes a lip member 30. The lip member 30 is arranged in a gap between the front edge 20a of the molding 20 and the vehicle body 12. The lip member 30 is supported by a shaft 32 and is configured to be able to swing between an open position (the position shown by the broken line in FIG. 2) and a closed position (the position shown by the solid line in FIG. 2). ing. Although not particularly limited, the lip member 30 is made of a resin material.

リップ部材30が開放位置にあるときは、リップ部材30の前端30aが車体12から離間して、リップ部材30の前端30aと車体12との間に隙間が形成される。一方、リップ部材30が閉塞位置にあるときは、リップ部材30の前端30aが車体12に接触して、リップ部材30と車体12との間の隙間が閉塞される。 When the lip member 30 is in the open position, the front end 30a of the lip member 30 is separated from the vehicle body 12, and a gap is formed between the front end 30a of the lip member 30 and the vehicle body 12. On the other hand, when the lip member 30 is in the closed position, the front end 30a of the lip member 30 contacts the vehicle body 12, and the gap between the lip member 30 and the vehicle body 12 is closed.

図3に示すように、シャフト32には、ねじりばね40が設けられている。ねじりばね40は、リップ部材30を開放位置に向けて付勢している。但し、ねじりばね40による付勢力は、比較的に小さい。これにより、電動車10がある程度の速度で走行したときは、走行に伴う風圧を受けたねじりばね40が、閉塞位置へ移動するように構成されている。なお、リップ部材30を開放位置に向けて付勢する構成は、ねじりばね40に限定されない。例えば、リップ部材30の一部が弾性変形可能に構成され、その弾性変形によってリップ部材30が開放位置と閉塞位置との間を揺動するとともに、閉塞位置に向けて付勢されてもよい。 As shown in FIG. 3, the shaft 32 is provided with a torsion spring 40. Torsion spring 40 biases lip member 30 toward the open position. However, the biasing force exerted by the torsion spring 40 is relatively small. As a result, when the electric vehicle 10 travels at a certain speed, the torsion spring 40 receives wind pressure from traveling and moves to the closed position. Note that the configuration for biasing the lip member 30 toward the open position is not limited to the torsion spring 40. For example, a portion of the lip member 30 may be configured to be elastically deformable, and the lip member 30 may swing between an open position and a closed position and be biased toward the closed position due to the elastic deformation.

一般に、モール20と車体12との間には、組み付け時の干渉を避けるために、一定の隙間を設ける必要がある。しかしながら、モール20と車体12との間に隙間が存在すると、電動車10の走行時に風切り音が発生する。このような風切り音は、本実施例の電動車10に限られず、エンジンが存在しない各種の電動車において、新たな問題となっている。特に、モール20が車体12の前部12fに位置する場合は、風切り音が発生しやすいとともに、車内のユーザによって認知されやすい。 Generally, it is necessary to provide a certain gap between the molding 20 and the vehicle body 12 in order to avoid interference during assembly. However, if a gap exists between the molding 20 and the vehicle body 12, wind noise will occur when the electric vehicle 10 runs. Such wind noise is a new problem not only in the electric vehicle 10 of this embodiment but also in various electric vehicles that do not have an engine. Particularly, when the molding 20 is located at the front portion 12f of the vehicle body 12, wind noise is likely to be generated and easily perceived by the user inside the vehicle.

上記の点に関して、本実施例の電動車10では、上述したリップ部材30が設けられている。電動車10が走行しているときは、モール20の前縁20aと車体12との間の隙間が、リップ部材30によって少なくとも部分的に閉塞される。これにより、当該隙間に起因する風切り音の発生が抑制される。一方、電動車10が停止しているときは、リップ部材30が車体12から離間することで、組み付け時に必要とされる隙間や、雨水等を排水するための隙間を確保することができる。 Regarding the above point, the electric vehicle 10 of this embodiment is provided with the lip member 30 described above. When the electric vehicle 10 is running, the gap between the front edge 20a of the molding 20 and the vehicle body 12 is at least partially closed by the lip member 30. This suppresses the generation of wind noise caused by the gap. On the other hand, when the electric vehicle 10 is stopped, the lip member 30 is separated from the vehicle body 12, so that a gap required during assembly and a gap for draining rainwater etc. can be secured.

ここで、リップ部材30の前端30aには、ゴム材料で構成された接点部34が設けられてもよい(図2参照)。接点部34を構成するゴム材料は、リップ部材30を構成する樹脂材料よりも柔軟であるとともに、当該樹脂材料より大きな密度を有する。従って、接点部34が存在することにより、車体12の塗装に与えるダメージが抑制される。また、接点部34の自重によって、リップ部材30が閉塞位置へ揺動することをアシストすることができる。 Here, a contact portion 34 made of a rubber material may be provided at the front end 30a of the lip member 30 (see FIG. 2). The rubber material that makes up the contact portion 34 is more flexible than the resin material that makes up the lip member 30, and has a higher density than the resin material. Therefore, the presence of the contact portion 34 suppresses damage to the paint on the vehicle body 12. Further, the weight of the contact portion 34 can assist the lip member 30 to swing to the closed position.
