Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a stand for supporting a vehicle body by swinging and protruding substantially vertically downward from the vehicle body when the motorcycle is stopped,
In particular, the present invention relates to a stand device which is driven by a motor to automatically swing.

2. Description of the Related Art Conventionally, a motorcycle is usually provided with a stand (main stand) for holding the vehicle body upright when the vehicle is stopped. The stands form a pair of left and right, and are stored in a substantially horizontal storage position at the rear when the vehicle is running, but when the vehicle is stopped, the stands are rocked forward and grounded. At this time, the stand swings further forward after landing and lifts the vehicle body,
Support the car body with the rear wheels off the ground.

A motorcycle has been conventionally known in which the motor is used to raise and lower such a stand. For example, in Japanese Utility Model Laid-Open No. 534564, a stand raising and lowering shaft is linked with a motor to raise and lower the stand. A motorcycle is shown which is adapted to do so.

Problems to be Solved The above stand is used to hold the motorcycle with the engine stopped in an upright state when the driver is absent.For example, for traveling, waiting for a signal at an intersection, etc. In the case of a temporary stop, the driver has to put his / her foot on the ground to hold the vehicle body in an upright state, which imposes a burden on the driver.

Accordingly, the present invention is intended to enable the vehicle body to be held upright by the stand even when the vehicle is temporarily stopped during traveling.

Therefore, according to the present invention, in the present invention, a stand that can be swung between a substantially horizontal storage position and a protruding position that vertically projects downwards and lifts and supports the vehicle body is provided by a motor. In a motorcycle stand device for driving and swinging, the first control means for driving the stand from the storage position to the projecting position by the motor to set the stand at the projecting position, and grounding the stand. It has a grounding detecting means for detecting, and a second control means for responding to the grounding detecting means to stop the driving of the motor and set the stand at the grounding position when the stand is grounded.

The first control means is used to support the vehicle body when not driving. That is, the stand is set to the projecting position as usual by the control means, and the vehicle body is securely supported by the stand by floating the rear wheel from the ground. On the other hand, when the vehicle is temporarily stopped during traveling, the motor is driven by the second control means to lower the stand from the storage position. The stand is grounded before reaching the projecting position, and at the same time when the grounding detecting means detects the grounding, the motor is stopped and the stand is held at that position. Therefore, the vehicle body is supported by this stand and does not fall to the left or right, so that it is not necessary for the driver to put his foot on the ground and hold the vehicle body in the upright state.
Moreover, since the stand is held in that position at the same time as the ground touches, the rear wheel remains in contact with the ground, the vehicle body does not move up and down before and after the vehicle is stopped, and the vehicle can be started smoothly thereafter.

Embodiment Hereinafter, the present invention will be described with reference to an illustrated embodiment.

FIG. 1 is a side view of a scooter type motorcycle having a stand device according to the present invention. Reference numeral 1 is a steering head having a steering wheel 2, 3 is a seat, and a low floor 4 is provided between the steering head 1 and the seat 3. A skeleton of the vehicle body is formed by a vehicle body frame 5 that descends from the lower portion of the steering head 1 and extends rearward below the floor 4 and upwardly toward the lower portion of the seat 3. Reference numeral 6 denotes a front wheel, which is suspended from the vehicle body via a front fork 7 and steered by the handle 2. The rear wheel 8 is rotatably attached to the rear end of a swing unit 9 integrated with the engine, and the front end of the swing unit 9 is swingable up and down on a bracket 11 integrated with the body frame 5 via a link device 10. It is connected. Front cover on the front of the vehicle
It is covered with 12, and the lower part of the rear seat 3 is covered with a body cover 13.

Also attached to the bracket 11 is a stand device 14, which will be described in more detail below. This stand device 14
Casing 15 incorporating a gear transmission mechanism, and the casing
A stand shaft 16 penetrating 15 left and right, and a pair of left and right stands 17 attached to both ends of the stand shaft 16,
And a motor 18 for rotating and driving the stand shaft 16 via the gear transmission mechanism. Therefore, the stand 17 is driven by the motor 18 and swings.
Is a storage position that extends substantially horizontally rearward from the stand shaft 16 as shown in FIG. 2 (a), and swings forward and downward from the storage position of (a) as shown in FIG. 2 (b). The position when the tip first touches the ground g (ground contact position), and as shown in FIG. 2 (c), it further swings after touching the ground and goes beyond the position perpendicular to the ground g to reach slightly ahead of it. It can be held and set in three positions, that is, the opened position (protruding position). The stand 17 is held at the storage position (a) during traveling. When the vehicle is not running, the stand 17 is driven by the motor 18 to the protruding position (c), and the rear wheels 8
With the vehicle lifted from the ground g, the weight of the vehicle body is reliably supported by the left and right stands 17 and the front wheels. The state of (b) is used when the vehicle is temporarily stopped while the driver is still on board.
In this state, the rear wheels 8 are in contact with the ground and support the weight of the vehicle body together with the front wheels 6, and the stand 17 merely swings to the storage position or the ground contact position. Therefore, the state (a) changes to the state (b). The transition is extremely easy with the driver still on board. Then, the left and right stands 17 that are in contact with the ground prevent the vehicle body from falling to the left or right, so that the vehicle body does not need to stand on its own and the driver does not have to keep his or her body upright by putting his or her feet on the ground. In addition, re-starting is also extremely smooth. Below, the second
The state of FIG. 2B is called the self-standing state, and the state of FIG. 2C is called the standing state. FIG. 1 also shows a standing state.

Next, the structure of the stand device 14 will be described in detail with reference to FIG. The casing 15 of the stand device 14 has a shaft 19 at its lower portion.
And a bracket 21 fixed to a cross pipe 20 connecting the left and right body frames 5 via a shaft 22 and a mount rubber 23. . Therefore, the casing 15 can rotate around the shaft 19 within the elastic range of the mount rubber 23. The motor 18 is fixed to the casing 15, and the rotation of the motor 18 is transmitted to the stand shaft 16 via the gear transmission mechanism 24 in the casing 15. Gear transmission mechanism
24 is configured as follows. A gear 26 provided on the motor shaft 25 meshes with a gear 28 provided on the worm shaft 27, and a worm 29 of the worm shaft 27 meshes with a worm wheel 31 of the intermediate shaft 30. The small gear 32 provided on the intermediate shaft 30 meshes with the sector gear 33 attached to the stand shaft 16, and the rotation of the motor 18 is decelerated by the gear transmission mechanism 24 configured as described above to increase the stand shaft 16. The stand 17 is oscillated in accordance with the rotation direction of the motor 18 from the storage position shown by the chain line in the figure to the projecting position shown by the solid line, or from the projecting position to the storage position.

At the protruding position of the stand 17, a normally closed micro switch S1 that engages with the stand 17 and opens is provided.
Similarly, a normally closed micro switch S2 that engages with the stand 17 and is opened is provided at the storage position of the stand 17, and it is detected by these switches S1 and S2 that the stand 17 reaches the projecting position and the storage position. To be done. The stand 17 can be set to the above-described grounding position in addition to the protruding position and the storage position, and this grounding position is detected as follows. If the stand 17 comes into contact with the ground while the stand 17 rotates from the stored position toward the protruding position, a torque around the shaft 19 acts on the casing 15 due to the reaction force from the ground, and the casing 15
Compresses the mount rubber 23 fitted on the upper shaft 22 and rotates a little around the shaft 19. As a result, the casing 15
The contact piece 34 provided on the bracket 21 engages with the normally closed micro switch S3 provided on the bracket 21 to open the switch S3, whereby the grounded position is detected. These switches S1, S2, S3 are incorporated in the drive circuit of the motor 18, and when the stand 17 reaches the projecting position, the storage position, or the grounding position, the circuit is opened to stop the motor 18.

The motor 18 is started by the standing switch 35 when driving the stand 17 from the storage position to the projecting position, the self-standing switch 36 when driving the stand 17 from the storage position to the grounding position, and when driving the stand 17 from the projecting position or the grounding position to the storage position. Storage switch 37-3
This is done by operating one of the switches (see FIGS. 6 to 12). As shown in Fig. 4, the standing switch
Reference numeral 35 is an ignition switch operated by a key provided on the inner box 38 inside the front cover 12.
The self-supporting switch 36 and the storage switch 37 are integrally combined with each other and are provided near the handle 2. FIG. 5 is an explanatory diagram showing the operation of the ignition switch 39. When the ignition switch 39 is rotated in the direction of the arrow from the ON position shown by the dotted line in the figure, the engine stops at the OFF position and the ignition switch 39 is pushed in at the PUSH position. Then, when the stand 17 is further rotated to the ON position, the standing switch 35 is closed and the motor 18 is started to drive the stand 17 to the protruding position. Therefore, the engine is inevitably stopped when the operation of raising the vehicle body is performed. When the ignition switch 39 is further rotated from the stand ON position, the handle is locked. The switches 36 and 37 are opened and closed by a common operation piece 40. When the operation piece 40 is moved from an intermediate neutral position to one side, the self-standing switch 36 is closed, and when it is moved to the other side, the storage switch 37 is closed.
Since the switches 36 and 37 are provided adjacent to the steering wheel 2, they can be easily operated while driving the vehicle.

FIG. 6 is a circuit diagram showing an example of the control circuit of the motor 18 and showing the state when the stand is housed. The switches S1, S2, S3, 35, 36, 37 are incorporated as shown. 41 is a power supply. 42 ₁ and 42 ₂ are relays R ₁ and R ₂ respectively
The switch 43 operated by means of is a vehicle speed switch which is closed when the vehicle speed is 0 km / H or at an extremely low vehicle speed. stand
17 opens the closing sensing switch S2 because the storage position, hence the relay R ₂ regardless of the state whether the storage switch 37 is not energized, the changeover switch 42 ₂ is grounded via the contact b _2. Although the protrusion detection switch S1 and the ground detection switch S3 are closed, the standing switch 35 and the self-supporting switch 36 are open, so the relay R ₁ is not energized, and the changeover switch 42 ₁ is also grounded via the contact b ₁ . No current flows through the motor 18.

When the standing up switch 35 is turned on from this state to turn the vehicle upright, the standing up switch 35 is operated after the engine is stopped as described above, and therefore the vehicle speed switch 43 is also closed at this time and the relay R ₁ Is energized and the changeover switch
Switch 42 ₁ to contact a ₁ (Fig. 7). Therefore, a current i in the direction of the arrow flows through the motor 18, causing the motor 18 to rotate in the forward
Swing 17 toward the protruding position. When the stand 17 is grounded on the way, the ground detection switch S3 opens, but this does not change the energized state of the relay R ₁ . Then, when the stand 17 reaches the projecting position, the projecting detection switch S1 is opened, and the changeover switch 42 ₁ is switched to the contact b ₁ , so that the motor 18 is stopped and the stand 17 is held at the projecting position to maintain the vehicle body in the standing state. (Fig. 8).

When the stand-alone switch 36 is turned on from the state shown in FIG. 6 in order to change the stand storage state to the self-standing state, if the vehicle speed switch 43 is closed at this time, the circuit of the relay R ₁ is closed and the changeover switch 42 ₁ is turned on. because switched to contact a _1, the seventh forward current i in the same manner as in the standing operation of the diagram flows in the motor 18, the stand 17 is swung toward the ground position (Figure 9). And since the ground sensing switch S3 and stand 17 are ground to release the energization of the relay R ₁ is opened, the changeover switch 42 ₁ contact b
_It is switched to ₁ and the motor 18 stops (Fig. 10). This self-sustaining operation can be performed only when the vehicle speed is 0 or sufficiently low and the vehicle speed switch 43 is closed.

FIG. 11 shows the state of the circuit when the stand 17 is driven from the protruding position or the grounded position to the storage position. Storage switch 37
And since the closing sensing switch S2 is closed relay R ₂ is energized, the changeover switch 42 ₂ is connected to the contact a _2.
On the other hand, since the standing switch 35 and the self-supporting switch 36 are open, the changeover switch 42 ₁ is connected to the contact b ₁ side, and the current i ₁ flows from the switch 42 ₂ side to the switch 42 ₁ side in the motor 18, and the motor 18 Reverse to pull up the stand 17 to the storage position. This stand storage operation can be performed regardless of whether the vehicle speed switch 43 is opened or closed. Further, as can be seen from FIGS. 8 and 10, in the standing state and the self-standing state, the circuit is placed in a state where it can be immediately moved to the storage operation.

FIG. 12 shows another circuit example, in which the switches having the same effects as the switches in the circuit are designated by the same reference numerals. When the upright switch 35 is closed, the thyristor 44 ₁ becomes conductive and the relays 45 ₁ and 45 ₂ are energized (at this time, S1 is closed), the changeover switch 42 ₁ becomes the contact a ₁ , and the changeover switch 42 ₂ becomes the contact b. _The electric current i flows through the motor 18 connected to the motor ₂ , and the motor 18 rotates in the normal direction until the protrusion detection switch S1 is opened. When closing the switch by tilting the operation piece 40 from the neutral position shown to the storage switch 37 side, the relay 46 in conduction thyristor 44 _{2 1,} 46
₂ is energized (S2 is closed at this time), and the changeover switch 4
2 ₁ is connected to the contact b ₁ and the changeover switch 42 ₂ is connected to the contact a _{2 so} that a current i ₁ flows through the motor 18, and the motor 18 reverses until the storage switch S2 is opened. When the self-supporting switch 36 is closed by the operation piece 40, the relays 45 ₁ , 45 _{2 are} caused by the current flowing through the thyristor 44 ₃ , the ground detection switch S3 and the protrusion switch S1.
Is energized, the motor 18 rotates in the normal direction in the same manner as described above, and stops when the ground contact detection switch S3 opens.

FIG. 13 shows a modification of the stand 17. In this modified example, a rear end of an arm member 48 is pivotally attached to a bracket 47 projectingly provided at an intermediate rear portion of the stand 17, and extends forward.
An auxiliary wheel 50 is rotatably supported by a front end of the arm member 48 via a shaft 49. The front end of the arm member 48 is pulled upward by the spring 51, and when the stand 17 is in the projecting position shown by the solid line in FIG. 13, the auxiliary wheel 50 is located above the tread bar 52. Do not ground.
In the figure, the state when the stand 17 is in the storage position is shown by a chain line, and the state when the stand 17 is in the grounding position is shown by a dotted line (however, the spring 51 is not shown). At the grounding position, the auxiliary wheel 50 is grounded as shown. Since the auxiliary wheels 50 are elastically supported by the springs 51 on the stand 17 as described above, and such auxiliary wheels 50 are individually provided on the left and right stands 17, respectively, the ground g has unevenness. However, each auxiliary wheel 50 is surely grounded to support the vehicle body in an independent state. In addition, the cushioning action of the spring 51 reduces the impact at the time of contact with the ground, and it is also possible to travel at a low speed while keeping the vehicle body self-supporting by the stand 17 via the auxiliary wheels 50, and a temporary stop operation during traveling. Can be performed extremely smoothly.

Since the gears of the gear transmission mechanism 24 are always meshed with each other, the stand 17 is fixed to the position where the motor 18 is stopped at the ground contact position or the projecting position to support the vehicle body. Therefore, the stand 17 cannot be pushed forward to swing the stand 17 to the storage position by the force of the return spring as in the conventional case, and the motor 18 must be operated to return the stand 17 to the storage position. So 14th
In the embodiment shown in the figure, the gear transmission 24 is constructed so that it can also be operated to store the stand as in the conventional case.
In this embodiment, the intermediate shaft 100 is further interposed between the intermediate shaft 30 and the worm shaft 27, the worm 29 is engaged with the worm wheel 101 attached to the intermediate shaft 100, and the small gear provided on the intermediate shaft 100. 102 is meshed with the gear 103 of the intermediate shaft 30, and the sector gear 33 further has a spline 53 on the stand shaft 16.
Are fitted through. That is, the sector gear 33 rotates integrally with the stand shaft 16, but is slidable in the axial direction,
A solid line position (locking position) that meshes with the small gear 32 and a chain line position (unlocking position) that is out of mesh with the small gear 32 can be occupied. The sector gear 33 is urged toward the locking position by a spring 54, and is pressed to the unlocking position by the lever member 55 from the opposite side. The lever member 55 is pivotally supported by the casing 15 through a shaft 56 in the middle, and the tip of one arm portion is in contact with the boss portion of the sector gear 33 so as to face the spring 54. The other arm piece of the lever member 55 protrudes from the casing 15 to the outside and
It is 104.

Normally, the sector gear 33 is in the solid line position where it is pushed by the spring 54 and meshes with the pinion gear 32. In this state, the stand 17 cannot be returned from the projecting position to the storage position unless it is driven by the motor 18. In other words, the stand 17 is locked in the protruding position. When the pedal 104 is depressed with the foot, the fan gear 33
Compresses the spring 54 to occupy the position of the chain line, and the small gear 32 and the sector gear 33 are disengaged from each other. That is, the stand 17 is unlocked and can be returned to the storage position manually.

FIG. 15 shows a modification of FIG. In this modification, the intermediate shaft 30 is axially supported so as to be slidable in the axial direction,
The gear 103 is spline-fitted to the intermediate shaft 30, and the small gear 32
Is fixed. A spring 54 is provided between the gear 103 and the pinion 32, and the spring 54 urges the pinion 32 to the solid line position (locking position) in the figure where it meshes with the sector gear 33. When the pedal 104 is depressed, the small gear 32 moves leftward together with the intermediate shaft 30 to occupy the position indicated by the chain line in the figure, and the small gear 32 and the sector gear 33 are disengaged from each other. That is, the stand is unlocked and can be manually returned to the storage position.

By doing so, it is convenient because the stand 17 can be erected by either motor driving or human power depending on the situation, and for example, by using the pedal 104, the vehicle in which the stand 17 is locked and erected can be erected. If the stand 17 is unlocked and the vehicle body is pushed forward as it is, the stand 17 can be housed and started without operating the motor 18.

However, on the other hand, another person can unlock the stand 17 with the pedal 104 to easily carry away the vehicle, which is not preferable for theft prevention. For this reason, it is desirable that the operating member is provided at a locked place that cannot be accessed by others.

FIG. 16 shows still another embodiment suitable for such a demand. Although the gear transmission mechanism of this embodiment is the same as that of FIG. 14, a cable 57 is bonded to the lever member 55. The cable 57 is slidably inserted in the sheath tube 58, and is connected to the base of the operation lever 59 at the other end. Fan gear 33,
The lever member 55 and the operating lever 59 normally occupy the solid line position (locking position) by the urging force of the spring 54, but when the operating lever 59 is set to the chain line position, the lever member 55 and the fan gear 33 also move to the chain line position. The small gear 32 and the sector gear 33 are disengaged from each other and are in an unlocked state. The operating lever 59 is seat 3
It is provided in the portion surrounded by the body cover 13 below.

FIG. 18 is a perspective view showing the upper portion of the body cover 13 with the seat 3 removed. Inside the body cover 13 is an article storage unit 60 for storing a helmet or the like. The seat 3 is attached to the hinge 61 at the front end so as to be openable and closable up and down, and covers the opening of the article storage unit 60 so as to be locked on the body cover 13. The operation lever 59 is an article storage unit 60.
It is provided at the rear of the. Therefore, unless the key is removed and the seat 3 is lifted up, the operation lever 59 cannot be accessed. Therefore, another person cannot operate the operation lever 59 unintentionally to bring the stand 17 in the locked state into the unlocked state. . The installation position of the operation lever 59 is not limited to the lower portion of the seat, and other storage boxes with keys, the inner box 38 described above, and the like can be used.

A modification similar to that of FIG. 15 is possible in the embodiment of FIG. This is shown in FIG. In this modification, a lever 55 is provided instead of the pedal 104 in FIG. 15, and a cable 57 is connected to the lever 55.

As described above, according to the present invention, the stand, which is swingable between the substantially horizontal storage position and the substantially vertically downward projecting position for lifting and supporting the vehicle body, is driven by the motor to swing. In a motorcycle stand device, the stand is set to the protruding position by driving the stand from the storage position to the protruding position by the motor.
Second control means, grounding detection means for detecting grounding of the stand, and second grounding means for responding to the grounding detection means to stop driving of the motor and set the stand at the grounding position. Since the control means is provided, when the vehicle is temporarily stopped during traveling, the stand is set to the grounding position while the driver is still on the vehicle and the front and rear wheels are in contact with the ground to prevent the body from collapsing. It is possible to make the vehicle stand on its own without holding the feet on the ground and keeping the vehicle upright.
