Description

  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.

  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.

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.

  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.

  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. .

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.

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.

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.

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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

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.

  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.

  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.

  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.

  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.

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.

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.

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.
