Description

本発明は、車両の駆動方式を４輪駆動又は２輪駆動に切換操作可能であるとともに、デフロックをオン又はオフに操作可能な操作スイッチを具備した駆動方式切換装置に関するものである。   The present invention relates to a drive system switching device including an operation switch capable of switching a vehicle drive system to a four-wheel drive or a two-wheel drive and operating a differential lock on or off.

４輪駆動車には、駆動方式を４輪駆動又は２輪駆動に選択的に切り換えるための切換スイッチと、前輪を一体として駆動させるデフロックのオンオフ操作を行うためのデフロック操作スイッチとを有した駆動方式切換装置を具備したものがあり、例えば４輪バギー等においては、かかる駆動方式切換装置がハンドルバーに固定されるようになっている。然るに、駆動方式を何れに選択したのかを運転者が容易に判別し得るべく、従来、切換スイッチ及びデフロック操作スイッチを押圧操作により突出状態又は没入状態とし得る２つの押しボタンスイッチと、何れかの操作を不可能とする遮蔽板とを有した駆動方式切換装置が例えば特許文献１にて開示されている。   The four-wheel drive vehicle has a changeover switch for selectively switching the driving method to four-wheel drive or two-wheel drive, and a drive having a diff lock operation switch for performing on / off operation of a diff lock for driving the front wheels integrally. For example, in a four-wheel buggy, the drive system switching device is fixed to the handlebar. However, in order to enable the driver to easily determine which driving method has been selected, conventionally, there are two push button switches that can be changed into a protruding state or an immersive state by pressing the changeover switch and the differential lock operation switch, For example, Patent Document 1 discloses a drive system switching device having a shielding plate that cannot be operated.

かかる文献にて開示された駆動方式切換装置は、２つの押しボタンを併設させるとともに、それらに亘って揺動可能とされて何れか一方の押しボタンの上部を覆う遮蔽板を有している。そして、切換スイッチとしての押しボタン（第１の押しボタン）が突出状態である場合、デフロック操作スイッチとしての押しボタン（第２の押しボタン）が没入状態とされて、その上部に遮蔽板が位置して押圧操作が不可能とされるとともに、第１の押しボタンを押圧操作して没入状態とすると、遮蔽板を当該第１の押しボタン上まで揺動可能とし、第２の押しボタンを押圧操作可能としていた。
特開２００２−８７０８７号公報 The drive system switching device disclosed in this document has two push buttons, and has a shielding plate that can swing over the push buttons and covers the upper part of one of the push buttons. When the push button (first push button) as the changeover switch is in the protruding state, the push button (second push button) as the differential lock operation switch is set in the immersive state, and the shielding plate is positioned above the push button. When the first push button is pressed and made into an immersive state, the shielding plate can be swung over the first push button and the second push button is pressed. It was possible to operate.
JP 2002-87087 A

しかしながら、上記従来の駆動方式切換装置においては、何れかの操作を規制するための遮蔽板が揺動するものであったため、その揺動範囲のスペースが必要となり、装置全体が大型化してしまうという問題があった。特に、第１の押しボタンと第２の押しボタンとの離間寸法がレイアウト上大きくなると、揺動範囲が増大して装置の大型化が顕著になるとともに、当該大きな揺動範囲内には他のスイッチ類や表示を形成することができず、レイアウトの自由度も低下してしまう。   However, in the above conventional drive system switching device, since the shielding plate for restricting any operation is oscillated, a space in the oscillating range is required, and the entire device is increased in size. There was a problem. In particular, when the distance between the first push button and the second push button is increased in the layout, the swing range is increased and the size of the device is significantly increased. Switches and displays cannot be formed, and the degree of freedom in layout also decreases.

本発明は、このような事情に鑑みてなされたもので、装置全体の小型化を図ることができるとともに、装置のレイアウトの自由度を向上させることができる駆動方式切換装置を提供することにある。   The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a drive system switching device capable of reducing the size of the entire apparatus and improving the degree of freedom of layout of the apparatus. .

請求項１記載の発明は、車両の駆動方式を４輪駆動又は２輪駆動に切換操作可能であるとともに、デフロックをオン又はオフに操作可能な操作スイッチを具備した駆動方式切換装置において、前記操作スイッチは、中立位置で４輪駆動方式とするとともに、押圧操作により軸を中心に揺動して２輪駆動への切換操作及びデフロックのオン操作が行われるシーソー式操作ノブを有するとともに、当該シーソー式操作ノブによる２輪駆動への切換操作又はデフロックのオンへの切換操作を選択的に規制すべく摺動可能なスライド部材を設け、且つ、前記スライド部材には、切換操作の選択的な規制時、摺動によって前記シーソー式操作ノブの下面下に位置してその操作を規制する規制部が形成されたことを特徴とする。 According to the first aspect of the present invention, there is provided a drive system switching device including an operation switch capable of switching a vehicle drive system to a four-wheel drive or a two-wheel drive and capable of operating a differential lock on or off. switch, with a four-wheel drive system in neutral position, and has a see-saw type operation knob switching operation and differential lock oN operation to swings around in two-wheel drive shaft is performed by the pressing operation, the seesaw the switching operation to the on-switching operation or differential lock to two-wheel drive according to formula operation knob selectively slidable slide member so as to provided regulations, and, said the sliding member, selective regulation of switching operation In some cases, a restricting portion is formed to be positioned under the lower surface of the seesaw type operation knob by sliding to restrict its operation.

請求項１の発明によれば、スライド部材の摺動によりシーソー式操作ノブによる２輪駆動への切換操作又はデフロックのオンへの切換操作を選択的に規制することができるので、装置全体の小型化を図ることができるとともに、装置のレイアウトの自由度を向上させることができる。 According to the first aspect of the present invention, the switching operation to the two-wheel drive by the seesaw type operation knob or the switching operation to turn on the diff lock can be selectively restricted by sliding of the slide member. And the degree of freedom of device layout can be improved.

更に、スライド部材の摺動によりシーソー式操作ノブの揺動操作を規制するので、それぞれの操作が独立した操作ノブを有し、各操作ノブの操作を規制するものに比べ、装置全体の更なる小型化を図ることができる。 Furthermore , since the swing operation of the seesaw type operation knob is regulated by the sliding of the slide member, each operation has an independent operation knob, and the whole apparatus is further compared with the one that regulates the operation of each operation knob. Miniaturization can be achieved.

以下、本発明の実施形態について図面を参照しながら具体的に説明する。
第１の実施形態に係る駆動方式切換装置は、４輪バギーのハンドルバーにおける把持グリップ近傍に固定されて、運転者が２輪駆動又は４輪駆動の何れかに駆動方式を切換可能であって、且つ、デフロックのオン、オフ操作が可能とされたものである。具体的には、本駆動方式切換装置は、図１及び図２に示すように、スイッチケース３と、操作ノブ１と、スライド部材２とから主に構成されている。 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The drive system switching device according to the first embodiment is fixed in the vicinity of the grip grip on the handlebar of the four-wheel buggy, and the driver can switch the drive system to either two-wheel drive or four-wheel drive. In addition, the differential lock can be turned on and off. Specifically, as shown in FIGS. 1 and 2, the present drive system switching device mainly includes a switch case 3, an operation knob 1, and a slide member 2.

スイッチケース３は、駆動方式切換装置の筐体を構成するとともに、その上面に操作ノブ１及びスライド部材２が形成されたものである。かかるスイッチケース３の表面における、操作ノブ１近傍には、同図に示すように、駆動方式が２輪駆動方式である旨を示す「２ＷＤ」、４輪駆動方式である旨を示す「４ＷＤ」、及びデフロックがオンであることを示す「ＬＯＣＫ」なる表示が印刷してある。   The switch case 3 constitutes a housing of the drive system switching device, and has an operation knob 1 and a slide member 2 formed on the upper surface thereof. In the vicinity of the operation knob 1 on the surface of the switch case 3, as shown in the figure, “2WD” indicating that the driving method is the two-wheel driving method and “4WD” indicating that the driving method is the four-wheel driving method. And “LOCK” indicating that the diff lock is on.

操作ノブ１は、４輪バギーの駆動方式を４輪駆動又は２輪駆動に切換操作可能であるとともに、デフロックをオン又はオフに操作可能な操作スイッチの一部を構成するもので、中立位置から左右方向に揺動可能とされた所謂シーソー式操作ノブから成る。具体的には、図５及び図６に示すように、操作ノブ１は、スイッチケース３に配設された軸Ｌにより支持されており、当該操作ノブ１の右側を押圧操作すると、軸Ｌを中心に右方向ａに揺動するとともに、左側を押圧操作すると、軸Ｌを中心に左方向ｂに揺動可能とされている。   The operation knob 1 can be operated to switch the four-wheel buggy drive system to four-wheel drive or two-wheel drive, and constitutes a part of an operation switch that can be operated to turn the differential lock on or off. It consists of a so-called seesaw type operation knob that can swing in the left-right direction. Specifically, as shown in FIGS. 5 and 6, the operation knob 1 is supported by a shaft L disposed in the switch case 3, and when the right side of the operation knob 1 is pressed, the shaft L is moved. It swings in the right direction a around the center and can be swung in the left direction b around the axis L when the left side is pressed.

これにより、操作ノブ１は、中立位置（揺動しない状態）、右方向への揺動位置（図５の二点鎖線で示した状態）、及び左方向への揺動位置（図６の二点鎖線で示した状態）の３つの状態が維持されるよう構成されている。そして、各状態においてそれぞれ図示しない所定の回路が形成され、操作ノブ１が中立位置においては４輪駆動、右方向への揺動位置においては２輪駆動、左方向への揺動位置においてはデフロックがオンされるように切換操作可能とされている。   As a result, the operation knob 1 has a neutral position (in a state where it does not swing), a swing position in the right direction (a state indicated by a two-dot chain line in FIG. 5), and a swing position in the left direction (two in FIG. 6). The three states (states indicated by dotted lines) are maintained. In each state, a predetermined circuit (not shown) is formed. When the operation knob 1 is in the neutral position, the four-wheel drive is performed, the two-wheel drive is performed in the swinging position in the right direction, and the differential lock is in the swinging position in the left direction. The switching operation can be performed so that is turned on.

スライド部材２は、スイッチケース３の上面上を直線状（図１中左右方向）に摺動可能とされたもので、図３及び図４に示すように、上面視略Ｕ字状に形成された部材から成るものである。かかるスライド部材２の略中央には上方に突出した摘み部２ａ、第１規制部２ｂ及び第２規制部２ｃが形成されており、摘み部２ａを指で摘んでスライド部材２を左右方向に摺動させると、当該第１規制部２ｂ及び第２規制部２ｃが左右の各所定位置まで移動するようになっている。   The slide member 2 is slidable on the upper surface of the switch case 3 in a straight line shape (left and right direction in FIG. 1), and is formed in a substantially U shape when viewed from above as shown in FIGS. It consists of a member. A knob portion 2a, a first restriction portion 2b, and a second restriction portion 2c projecting upward are formed at substantially the center of the slide member 2, and the slide member 2 is slid in the left-right direction by picking the knob portion 2a with a finger. When moved, the first restricting portion 2b and the second restricting portion 2c are moved to respective left and right predetermined positions.

即ち、操作ノブ１が中立位置にある状態で、スライド部材２を右方向へ摺動させ、図３及び図５に示す状態とすると、当該スライド部材２の第１規制部２ｂが操作ノブ１の左側下面１ａ下に位置することとなり、図５中ａ方向への揺動操作が許容されつつ同図中ｂ方向への揺動操作が規制される一方、スライド部材２を左方向へ摺動させ、図４及び図６に示す状態とすると、当該スライド部材２の第２規制部２ｃが操作ノブ１の右側下面１ｂ下に位置することとなり、図６中ｂ方向への揺動操作が許容されつつ同図中ａ方向への揺動操作が規制される。   That is, when the slide member 2 is slid rightward in a state where the operation knob 1 is in the neutral position, and the state shown in FIGS. 3 and 5 is established, the first restricting portion 2b of the slide member 2 is It is located below the left lower surface 1a, and while swinging operation in the direction a in FIG. 5 is allowed, swinging operation in the direction b in FIG. 5 is restricted, while the slide member 2 is slid leftward. 4 and 6, the second restricting portion 2c of the slide member 2 is positioned below the right lower surface 1b of the operation knob 1, and the swinging operation in the direction b in FIG. 6 is allowed. However, the swinging operation in the direction a in FIG.

従って、スライド部材２が右側にある状態では、駆動方式を４輪駆動から２輪駆動に切り換え可能とするとともに、デフロックをオンして４輪バギーの前輪を一体として駆動させることが不可能とされている。また、スライド部材２が左側にある状態では、デフロックのオンが可能であるとともに、駆動方式を２輪駆動に切り換え操作するのが不可能とされている。   Therefore, in a state where the slide member 2 is on the right side, the drive system can be switched from four-wheel drive to two-wheel drive, and it is impossible to drive the front wheels of the four-wheel buggy as a whole by turning on the diff lock. ing. In addition, when the slide member 2 is on the left side, the differential lock can be turned on and the drive method cannot be switched to the two-wheel drive.

このように、本実施形態によれば、車両が２輪駆動であるとき、スライド部材２を操作しなければ、デフロックのオン操作が不可能とされている一方、デフロックがオンであるときも、スライド部材２を操作しなければ、２輪駆動への切換操作が不可能とされているので、操作の確実性を図ることができる。また、スライド部材２が直線状に摺動するものから成るため、従来の遮蔽板の如く揺動させる規制部材を具備させるものに比べ、装置の小型化を図ることができる。   Thus, according to the present embodiment, when the vehicle is two-wheel drive, if the slide member 2 is not operated, it is impossible to turn on the diff lock. On the other hand, when the diff lock is on, Since the switching operation to the two-wheel drive is impossible unless the slide member 2 is operated, the certainty of the operation can be achieved. Further, since the slide member 2 is configured to slide linearly, the apparatus can be reduced in size as compared with a conventional member that includes a regulating member that swings like a shielding plate.

更に、スライド部材２の摺動によりシーソー式操作ノブの揺動操作を規制するので、それぞれの操作が独立した操作ノブを有し、各操作ノブの操作を規制するものに比べ、装置全体の更なる小型化を図ることができる。即ち、１つのシーソー式操作ノブによって、駆動方式の切換操作及びデフロックのオン又はオフ操作が可能であるため、２つの操作ノブを有するものに比べて小型化可能とされ、更には、部品点数の削減を図ることができる。   Further, since the swing operation of the seesaw type operation knob is regulated by the sliding of the slide member 2, each operation has an independent operation knob, and the entire apparatus is further improved compared to the one that regulates the operation of each operation knob. The size can be reduced. That is, the switching operation of the drive system and the diff lock on / off operation can be performed by one seesaw type operation knob, so that the size can be reduced as compared with the one having two operation knobs. Reduction can be achieved.

次に、参考例について説明する。
参考例に係る駆動方式切換装置は、第１の実施形態と同様、４輪バギーのハンドルバーにおける把持グリップ近傍に固定されて、運転者が２輪駆動又は４輪駆動の何れかに駆動方式を切換可能であって、且つ、デフロックのオン、オフ操作が可能とされたものである。具体的には、本駆動方式切換装置は、図７及び図８に示すように、スイッチケース３と、第１操作ノブ４及び第２操作ノブ５と、スライド部材２とから主に構成されている。尚、第１実施形態と同様の構成要素には、同一の符号を付してある。 Next, a reference example will be described.
As in the first embodiment, the drive system switching device according to the reference example is fixed in the vicinity of the grip grip on the handlebar of the four-wheel buggy so that the driver can use either the two-wheel drive or the four-wheel drive. The switch can be switched, and the differential lock can be turned on and off. Specifically, as shown in FIGS. 7 and 8, the drive system switching device mainly includes a switch case 3, a first operation knob 4 and a second operation knob 5, and a slide member 2. Yes. In addition, the same code | symbol is attached | subjected to the component similar to 1st Embodiment.

スイッチケース３は、駆動方式切換装置の筐体を構成するとともに、その上面に第１操作ノブ４及び第２操作ノブ５が併設されている。これら第１操作ノブ４及び第２操作ノブ５は、押圧操作により突出状態又は没入状態とされる所謂押しボタン式操作ノブから成るものである。このうち第１操作ノブ４は、４輪バギーの駆動方式を切換操作可能なものであり、突出状態にて４輪駆動となり、没入状態にて２輪駆動になるよう、図示しない所定の回路が形成されるとともに、第２操作ノブ５は、デフロックのオン又はオフ操作可能なものであり、突出状態にてオフとなり、没入状態にてロックがオンするよう、図示しない所定の回路が形成されるようになっている。   The switch case 3 constitutes a housing of the drive system switching device, and a first operation knob 4 and a second operation knob 5 are provided on the upper surface thereof. The first operation knob 4 and the second operation knob 5 are so-called push button type operation knobs which are brought into a protruding state or an immersion state by a pressing operation. Of these, the first operation knob 4 is capable of switching the driving method of the four-wheel buggy, and a predetermined circuit (not shown) is provided so that the four-wheel drive in the protruding state and the two-wheel drive in the immersed state. At the same time, the second operation knob 5 can be operated to turn on or off the diff lock, and a predetermined circuit (not shown) is formed so that the second operation knob 5 is turned off in the protruding state and turned on in the immersed state. It is like that.

スライド部材２は、第１の実施形態と同様、スイッチケース３の上面上を直線状（図７中左右方向）に摺動可能とされたもので、上面視略Ｕ字状に形成された部材から成るものである。かかるスライド部材２の略中央には上方に突出した摘み部２ａ、第１規制部２ｂ及び第２規制部２ｃが形成されており、摘み部２ａを指で摘んでスライド部材２を左右方向に摺動させると、当該第１規制部２ｂ及び第２規制部２ｃが左右の各所定位置まで移動するようになっている。   As in the first embodiment, the slide member 2 is a member that is slidable on the upper surface of the switch case 3 in a straight line (left and right direction in FIG. 7), and is formed in a substantially U shape when viewed from above. It consists of A knob portion 2a, a first restriction portion 2b, and a second restriction portion 2c projecting upward are formed at substantially the center of the slide member 2, and the slide member 2 is slid in the left-right direction by picking the knob portion 2a with a finger. When moved, the first restricting portion 2b and the second restricting portion 2c are moved to respective left and right predetermined positions.

即ち、スライド部材２を右方向へ摺動させ、図９に示す状態とすると、当該スライド部材２の第１規制部２ｂが第２操作ノブ５の下面５ａ下に位置することとなり、第１操作ノブ４の押圧操作が許容されつつ第２操作ノブ４の押圧操作が規制される一方、スライド部材２を左方向へ摺動させ、図１０に示す状態とすると、当該スライド部材２の第２規制部２ｃが第１操作ノブ４の下面４ａ下に位置することとなり、第２操作ノブ５の押圧操作が許容されつつ第１操作ノブ４の押圧操作が規制される。   That is, when the slide member 2 is slid rightward to the state shown in FIG. 9, the first restricting portion 2b of the slide member 2 is located below the lower surface 5a of the second operation knob 5, and the first operation is performed. While the pressing operation of the knob 4 is allowed and the pressing operation of the second operation knob 4 is restricted, when the slide member 2 is slid leftward to obtain the state shown in FIG. The portion 2c is positioned below the lower surface 4a of the first operation knob 4, and the pressing operation of the first operation knob 4 is restricted while the pressing operation of the second operation knob 5 is allowed.

従って、第１実施形態と同様、スライド部材２が右側にある状態では、駆動方式を４輪駆動から２輪駆動に切り換え可能とするとともに、デフロックをオンして４輪バギーの前輪を一体として駆動させることが不可能とされて、スライド部材２が左側にある状態では、デフロックのオンが可能であるとともに、駆動方式を２輪駆動に切り換え操作するのが不可能とされているので、操作の確実性を図ることができる。   Therefore, as in the first embodiment, when the slide member 2 is on the right side, the drive system can be switched from four-wheel drive to two-wheel drive, and the front wheel of the four-wheel buggy is driven integrally by turning on the differential lock. In the state where the slide member 2 is on the left side, the diff lock can be turned on and the drive system cannot be switched to the two-wheel drive. Certainty can be achieved.

上記第１実施形態及び参考例に係る駆動方式切換装置によれば、スライド部材２が直線状に摺動するので、装置全体の小型化を図ることができるとともに、操作ノブの押圧操作を選択的に規制すべく遮蔽板等を揺動させるものに比べ、大きな揺動範囲を必要とせず、装置のレイアウトの自由度を向上させることができる。 According to the drive system switching device according to the first embodiment and the reference example , since the slide member 2 slides linearly, the entire device can be reduced in size and the pressing operation of the operation knob can be selectively performed. Compared with the case where the shielding plate or the like is swung so as to be restricted, a large swinging range is not required, and the degree of freedom in the layout of the apparatus can be improved.

以上、本実施形態について説明したが、本発明はこれらに限定されず、４輪バギーの他、他の種々車両（例えば４輪駆動又は２輪駆動を選択可能なＡＴＶや自動車等）に適用することができる。 Although the present embodiment has been described above, the present invention is not limited thereto, and is applicable to other various vehicles (for example, ATVs and automobiles capable of selecting four-wheel drive or two-wheel drive) in addition to four- wheel buggy. be able to.

スライド部材の摺動により、シーソー式操作ノブの２輪駆動への切換操作又はデフロックのオンへの切換操作を選択的に規制するとともに、スライド部材には、切換操作の選択的な規制時、摺動によって操作ノブの下面下に位置してその操作を規制する規制部が形成された駆動方式切換装置であれば、外観形状が異なるもの或いは他の機能が付加されたものにも適用することができる。 The sliding operation of the seesaw type operation knob to the two-wheel drive or the switching operation to turn on the differential lock is selectively restricted by sliding of the sliding member. As long as it is a drive system switching device that is located under the lower surface of the operation knob and is formed with a restricting portion that restricts its operation, it can be applied to devices with different external shapes or with other functions added. it can.
