Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は主として障害者や高齢者が車椅子として利用す
る、或いは、ゴルフカートとして使用する小型電動車に
関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a small electric vehicle mainly used by a disabled person or an elderly person as a wheelchair or as a golf cart.
この主の小型電動車において、従来は、操向車輪の最大
操向角を規制する規制機構が設けてあっただけである。In this main small-sized electric vehicle, conventionally, only a restricting mechanism for restricting the maximum steering angle of the steering wheel was provided.
この場合に、操向車輪は常に最大操向角まで操作される
ので、高速で走行している状態で最大角まで操向操作す
ると急ハンドル状態となって転倒等の危険があり、それ
だからといって、最大操向角を小さな角度に抑えてしま
ったら、路地を走行する際に小廻りができず、使いづら
い面もあった。In this case, since the steered wheels are always operated to the maximum steering angle, steering to the maximum angle while traveling at high speed may result in a sudden steering wheel and there is a danger of falling, etc. If the maximum steering angle was suppressed to a small angle, it was not possible to make a small turn when traveling on an alley, and it was difficult to use.
本発明の目的は、走行状態に応じて小廻り旋回できる状
態と小廻りが規制される状態とに使い分けできる小型電
動車を提供する点にある。An object of the present invention is to provide a small electric vehicle that can be used separately in a state where a small turn can be made and a state where the small turn is restricted according to the running state.

後に位置変更可能な機構を設けてあることにある。The characteristic configuration according to claim 1 is provided with a steering angle setting means for determining a steering range of a steering wheel and a maximum steering angle variable mechanism for changing the maximum steering angle by the steering angle setting means. The angle setting means is configured to define the left and right ends of the steering range of the steering wheel by abutting the restricting member and the protruding member that move relative to each other by steering the steering wheel, and the maximum steering angle variable. The mechanism switches between a state in which the regulation member can be guided and moved, and a state in which the regulation member can be fixedly held at the movement position, so that the maximum steering angle can be changed in equal amounts to the left and right by moving the regulation member in one direction. According to the characteristic structure according to claim 2, the front and rear wheels can be repositioned in order to adjust the front and rear wheel spacing without changing the mounting height of one of the front and rear wheels with respect to the body frame. Be equipped with a mechanism A.

規制部材（13）を、図示する矢印方向にスライド移動さ

行する路地裏等では、第２図で示す実線位置まで規制部
材（13）を後退させて最大操向角を大きくして、状況に
応じた走りができる。[Operation according to Claim 1] Referring to Fig. 2, the swinging restricting member (13) of the rod-shaped projection (12) swinging integrally with the operation of the steering handle (3) is illustrated. The maximum swing angle of the rod-like protrusion (12) can be set to any size by sliding and fixing in the direction of the arrow. Therefore, by providing such a mechanism (15) for varying the maximum steering angle, when a small turn is not required for straight traveling, the regulating member (13) is moved to the position of the imaginary line shown in FIG. In addition, the maximum steering angle is set to a small value, and on the back alley where a small turn is required and the vehicle travels at low speed, the maximum steering angle is increased by retracting the regulating member (13) to the solid line position shown in FIG. , You can run according to the situation.
又、左右の操向角を規制できる規制部材を一方向に移動
させるだけで、操向角の変更を左右同時に、かつ、等量
に行うことができるから、左右別々に調節操作する必要
がないとともに、最大操向角の変更量が左右で異なるこ
とがない。In addition, since the steering angle can be changed at the same time to the left and right and at the same amount only by moving the regulating member capable of regulating the left and right steering angles in one direction, it is not necessary to separately adjust the right and left sides. In addition, the maximum steering angle change amount does not differ between the left and right.
〔請求項１による効果〕 最大操向角可変構造により、その最大操向角の可変設定
操作が簡単で確実に行えるようにしながら、直進高速時
の走行安定性や路地裏等での低速走行時の小廻り性を向
上でき走行安全性に厳密な設計が必要な３輪形態を採る
ことの多い小型電動車に好適なものにし得た。[Effects of Claim 1] The maximum steering angle variable structure allows the maximum steering angle variable setting operation to be performed easily and surely, while ensuring stable running at high speeds in straight running and low speed running on the back alley. It can be made suitable for a small electric vehicle that often adopts a three-wheel configuration that requires a strict design for driving safety and can be improved.
〔請求項２による作用〕 例えば、後車輪の位置を変更する場合を第５図を参照し
て説明すると、ピローブロック（17）の付け替えで後車
輪（８）を前後に水平移動させることによって、前後車
輪間隔と操向車輪の操向角で決まる旋回半径を変更でき
る。したがって、前後車輪間隔を狭くすれば旋回半径を
小さくできて小廻り旋回が可能になるとともに、前後車
輪間隔を大きくすれば旋回半径を大きくできる。[Operation according to Claim 2] For example, a case of changing the position of the rear wheel will be described with reference to Fig. 5. By changing the pillow block (17), the rear wheel (8) is horizontally moved forward and backward. The turning radius determined by the front and rear wheel spacing and the steering angle of the steered wheels can be changed. Therefore, if the distance between the front and rear wheels is narrowed, the turning radius can be reduced to enable a small turn, and if the distance between the front and rear wheels is increased, the turning radius can be increased.
〔請求項２による効果〕 その結果、小廻り旋回が特に必要な場合には、前後車輪
間隔を小さくし、操向車輪の操向角だけでは得られない
小廻り性能を確保できるとともに、直線高速走行時に
は、前後車輪間隔を大きくして、走行安全性を確保でき
る。[Effects of Claim 2] As a result, when a small turn is particularly required, the front-rear wheel spacing can be reduced to ensure a small turning performance that cannot be obtained only by the steering angle of the steered wheels, and at the same time, for a straight high speed When traveling, the front and rear wheel spacing can be increased to ensure traveling safety.
又、前後車輪の間隔調整時には車輪の車体に対する高さ
が変化しないので、車高が変化しない利点がある。Further, since the height of the wheels with respect to the vehicle body does not change when the distance between the front and rear wheels is adjusted, there is an advantage that the vehicle height does not change.
ここに、操向車輪の最大操向角可変機構と前後車輪間隔
調節機構とを併用することによって、その機能をより高
めたものにすることができる。The maximum steering angle varying mechanism of the steered wheels and the front-rear wheel spacing adjusting mechanism are used together to enhance the function thereof.
