Description

電気自動車の前部構造Electric vehicle front structure
　本発明は、バンパ開口部から取り入れた走行風をエアガイドにより熱交換器へ案内する電気自動車の前部構造に関するものである。 The present invention relates to a front structure of an electric vehicle that guides a traveling wind taken from a bumper opening to a heat exchanger by an air guide.
　従来、バンパ開口部から取り入れた走行風を熱交換器に効率よく送るため、例えば特許文献１に記載されていえるように、バンパ開口部から熱交換器までの走行風路に、エアガイドを設けた車両の前部構造が知られている。 Conventionally, an air guide has been provided in the traveling air path from the bumper opening to the heat exchanger, as described in Patent Document 1, for example, in order to efficiently send the traveling air taken from the bumper opening to the heat exchanger. The vehicle front structure is known.
　しかしながら、従来の車両の前部構造にあっては、エアガイドが車両側面に沿った側壁のみを有するものとなっている。すなわち、この前部構造では、エアガイドの上部が開放しており、バンパ開口部から走行風路に取り入れられた走行風の一部は、バンパ開口部から上方向に向かって流れてしまう。
　そのため、この車両の前部構造を、バンパ開口部の上方に充電ポートを有する電気自動車に適用した場合、上方向に向かって流れた走行風により充電ポートの周囲に着氷し、充電ポートを覆うポートリッドが凍り付いて開かない等の問題が生じることがあった。 However, in the conventional front structure of a vehicle, the air guide has only a side wall along the side surface of the vehicle. That is, in this front structure, the upper part of the air guide is open, and a part of the traveling wind taken into the traveling air passage from the bumper opening flows upward from the bumper opening.
Therefore, when this front structure of the vehicle is applied to an electric vehicle having a charging port above the bumper opening, the traveling wind that flows upward causes icing around the charging port and covers the charging port. Problems such as the port lid icing up and not opening.

　本発明は、上記問題に着目してなされたもので、バンパ開口部の上方に配置した充電ポート周囲に、バンパ開口部から流れ込んだ走行風によって着氷することを防止できる電気自動車の前部構造を提供することを目的とする。 The present invention has been made paying attention to the above-mentioned problem, and is a front structure of an electric vehicle that can prevent icing due to traveling wind flowing from the bumper opening around the charging port arranged above the bumper opening. The purpose is to provide.
　上記目的を達成するため、本発明は、走行風を取り入れるバンパ開口部と、前記走行風を受ける熱交換器と、前記バンパ開口部の上方に配置した充電ポートと、を備えた電気自動車の前部構造を前提とする。
　この電気自動車の前部構造では、前記バンパ開口部から前記熱交換器までの走行風路に、車両上下方向及び車幅方向の全周方向を囲み、前記走行風を前記熱交換器へ案内するエアガイドを設けた構成とした。 In order to achieve the above object, the present invention provides a front of an electric vehicle including a bumper opening for taking in traveling wind, a heat exchanger for receiving the traveling wind, and a charging port disposed above the bumper opening. Assuming partial structure.
In the front structure of the electric vehicle, the traveling wind path from the bumper opening to the heat exchanger surrounds the entire circumferential direction in the vehicle vertical direction and the vehicle width direction, and guides the traveling wind to the heat exchanger. It was set as the structure which provided the air guide.
　よって、本発明では、走行風路に設けられて走行風を熱交換器へ案内するエアガイドが、車両上下方向及び車幅方向の全周方向を囲んだ構成とした。
　そのため、バンパ開口部から取り入れた走行風は、エアガイドによって車両上下方向の流れ及び車幅方向の流れがそれぞれ規制されつつ熱交換器へと案内される。すなわち、バンパ開口部の上方に配置した充電ポートに走行風が向かうことが規制される。
　これにより、バンパ開口部の上方に充電ポートを配置した電気自動車において、バンパ開口部から流れ込んだ走行風に粉雪等が含まれていても、この粉雪等が充電ポートの周囲に入り込むことが防止される。この結果、バンパ開口部から流れ込んだ走行風により、バンパ開口部の上方に配置した充電ポート周囲の着氷を防止できる。 Therefore, in the present invention, the air guide that is provided in the traveling wind path and guides the traveling wind to the heat exchanger is configured to surround the vehicle circumferential direction in the vehicle vertical direction and the vehicle width direction.
Therefore, the traveling wind taken from the bumper opening is guided to the heat exchanger while the flow in the vehicle vertical direction and the flow in the vehicle width direction are regulated by the air guide. In other words, the traveling wind is restricted from being directed to the charging port disposed above the bumper opening.
As a result, in an electric vehicle in which a charging port is arranged above the bumper opening, even if powdered snow or the like is included in the traveling wind flowing from the bumper opening, the powdered snow or the like is prevented from entering the periphery of the charging port. The As a result, it is possible to prevent icing around the charging port disposed above the bumper opening due to the traveling wind flowing from the bumper opening.

The upper guide portion 22 is formed with an opening 22a that communicates with the motor room 2 in which the heat exchanger 40 is disposed. A port bracket 34 to be described later is disposed inside the opening 22a (see FIG. 3). Note that the opening 22a is provided substantially at the center of the upper guide 22 and is open to the rear of the vehicle.
　前記アンダーパネル２３は、走行風路の下側を覆う平板である。このアンダーパネル２３は、車両後方に延在し、熱交換器４０やその後方に配置される図示しない走行駆動用モータユニット等の下側も一体的に覆う。 The under panel 23 is a flat plate that covers the lower side of the traveling air passage. The under panel 23 extends rearward of the vehicle and integrally covers the lower side of the heat exchanger 40 and a travel drive motor unit (not shown) disposed behind the heat exchanger 40.
　前記メンバ部材３０は、熱交換器４０及び充電ポート５０を保持する保持手段であり、ロアクロスメンバ３１と、垂直リテーナ３２と、アッパークロスメンバ３３と、ポートブラケット３４と、を有している。 The member member 30 is a holding means for holding the heat exchanger 40 and the charging port 50, and includes a lower cross member 31, a vertical retainer 32, an upper cross member 33, and a port bracket 34.
　前記ロアクロスメンバ３１は、車幅方向に延び、両端が図示しないサイドメンバに固定されて、熱交換器４０の下部を支持する。 The lower cross member 31 extends in the vehicle width direction, and both ends are fixed to side members (not shown) to support the lower part of the heat exchanger 40.
　前記垂直リテーナ３２は、下端部３２ａがロアクロスメンバ３１のほぼ中央に固定され、ほぼ鉛直方向に起立している。 The lower end 32a of the vertical retainer 32 is fixed substantially at the center of the lower cross member 31, and stands up in a substantially vertical direction.
　前記アッパークロスメンバ３３は、ロアクロスメンバ３１に対してほぼ平行に配置されると共に車幅方向に延び、両端が図示しないフェンダパネルに固定されて、熱交換器４０の上部を支持する。 The upper cross member 33 is arranged substantially parallel to the lower cross member 31 and extends in the vehicle width direction, and both ends are fixed to a fender panel (not shown) to support the upper portion of the heat exchanger 40.
　前記ポートブラケット３４は、垂直リテーナ３２とアッパークロスメンバ３３に固定され、車両前方に膨出して充電ポート５０を支持する。このポートブラケット３４は、水平上壁３４ａと、下端部３４ｂと、ポート取付壁３４ｃと、を有している。

　次に、作用を説明する。
　図４は、実施例に係る電気自動車の前部構造における走行風の流れを示す説明図である。 Next, the operation will be described.
FIG. 4 is an explanatory diagram illustrating a flow of traveling wind in the front structure of the electric vehicle according to the embodiment.
　実施例に係る電気自動車の前部構造における作用を「熱交換器への送風作用」と、「充電ポート周囲への着氷防止作用」と、「アッパーガイド部への着氷防止作用」と、に分けて説明する。 The action in the front structure of the electric vehicle according to the embodiment is “the air blowing action to the heat exchanger”, “the anti-icing action around the charging port”, “the anti-icing action to the upper guide part”, This will be explained separately.
　[熱交換器への送風作用]
　車両の走行に伴って、車両前方に開放したバンパ開口部１１から走行風が取り入れられる。バンパ開口部１１から流れ込んだ走行風（図４において矢印Ａで示す）は、エアガイド２０によって車両上下方向及び車幅方向の全周方向を囲まれた走行風路を流れ、図４において矢印Ｂで示すように熱交換器４０に向かう。 [Blowing action on heat exchanger]
As the vehicle travels, traveling wind is taken from the bumper opening 11 that opens to the front of the vehicle. The traveling wind (indicated by an arrow A in FIG. 4) that flows from the bumper opening 11 flows along a traveling wind path surrounded by the air guide 20 in the vehicle up-down direction and the entire circumferential direction of the vehicle width direction, and in FIG. As shown in FIG.
　すなわち、バンパ開口部１１から取り入れられて車両側部に沿って流れる走行風は、エアガイド２０の一対のサイドガイド部２１,２１によって流れが規制される。また、車両上方向に向かう走行風は、エアガイド２０のアッパーガイド部２２によって流れが規制される。また、車両下方向に向かう走行風は、エアガイド２０のアンダーパネル２３によって流れが規制される。 That is, the flow of the traveling wind that is taken in from the bumper opening 11 and flows along the side of the vehicle is regulated by the pair of side guide portions 21, 21 of the air guide 20. Further, the flow of the traveling wind traveling upward in the vehicle is restricted by the upper guide portion 22 of the air guide 20. Further, the flow of the traveling wind toward the lower side of the vehicle is restricted by the under panel 23 of the air guide 20.
　このため、バンパ開口部１１から取り入れられた走行風は、拡散することなく効率的に熱交換器４０へと案内され、熱交換器４０における冷熱性能の向上を図ることができる。 For this reason, the traveling wind taken from the bumper opening 11 is efficiently guided to the heat exchanger 40 without diffusing, and the cooling performance in the heat exchanger 40 can be improved.
　［充電ポート周囲への着氷防止作用］
　実施例に係る電気自動車の前部構造では、バンパ開口部１１の上方に、ポートハウジング５３に内蔵された充電ポート５０が配置されている。一方、車両上方向に向かう走行風は、エアガイド２０のアッパーガイド部２２によって流れが規制されて熱交換器４０へと案内される。 [Anti-icing action around the charging port]
In the front structure of the electric vehicle according to the embodiment, the charging port 50 built in the port housing 53 is disposed above the bumper opening 11. On the other hand, the flow of the traveling wind heading upward in the vehicle is guided to the heat exchanger 40 with the flow restricted by the upper guide portion 22 of the air guide 20.
　すなわち、アッパーガイド部２２によって、充電ポート５０に向かって流れる走行風が遮断される（図４において矢印Ｃで示す）。これにより、ポートハウジング５３の内部に粉雪等が入り込むことが防止され、充電ポート５０周囲への着氷を防止できる。 That is, the traveling wind flowing toward the charging port 50 is blocked by the upper guide portion 22 (indicated by an arrow C in FIG. 4). Thereby, powder snow or the like is prevented from entering the inside of the port housing 53, and icing around the charging port 50 can be prevented.
　特に、ポートハウジング５３の下部には、ポートリッド５４を固定するロック機構５５が設けられているが、このロック機構５５への着氷も防止される。このため、ロック機構５５が凍りついてポートリッド５４が開かないといった現象を防止できる。 In particular, a lock mechanism 55 for fixing the port lid 54 is provided at the lower portion of the port housing 53, but icing to the lock mechanism 55 is also prevented. For this reason, the phenomenon that the lock mechanism 55 freezes and the port lid 54 does not open can be prevented.
　［アッパーガイド部への着氷防止作用］
　実施例に係る電気自動車の前部構造では、車両上方向に向かう走行風の流れを規制するアッパーガイド部２２に、熱交換器４０を配置したモータルーム２に連通する開口部２２ａが形成されている。 [Anti-icing action on the upper guide]
In the front structure of the electric vehicle according to the embodiment, an opening 22a that communicates with the motor room 2 in which the heat exchanger 40 is disposed is formed in the upper guide portion 22 that restricts the flow of traveling wind toward the vehicle upward direction. Yes.
　すなわち、アッパーガイド部２２によって上方向に向かうことが規制された走行風のうち、一部の走行風は、図４において矢印Ｄで示すように、開口部２２ａを介してモータルーム２に流れる。つまり、アッパーガイド部２２は、上方向に向かう全ての走行風を遮断するわけではない。 That is, some of the traveling winds that are restricted from moving upward by the upper guide portion 22 flow into the motor room 2 through the opening 22a as indicated by an arrow D in FIG. That is, the upper guide portion 22 does not block all traveling winds directed upward.
　そのため、走行風に粉雪等が含まれていた場合に、この粉雪等を熱交換器４０の上方からモータルーム２内へ吹き抜けさせることができ、アッパーガイド部２２の裏面側に着氷することを防止できる。この結果、熱交換器４０の前側に雪や氷が蓄積することを防止できる。 For this reason, when powdered snow or the like is included in the traveling wind, the powdered snow or the like can be blown into the motor room 2 from the upper side of the heat exchanger 40 and can be icing on the back side of the upper guide portion 22. Can be prevented. As a result, it is possible to prevent snow and ice from accumulating on the front side of the heat exchanger 40.
