Description

[0001]
[Industrial application fields]
The present invention relates to a mobile power device for a vehicle. Here, the moving body is a sliding door or a lift-up type tail gate that is frequently used in a one-box type vehicle.
[0002]
[Prior art]
Conventional sliding doors are usually opened and closed by moving the operator's arm to the left and right, and open / close operations are more cumbersome than swing doors that can be opened and closed by moving the operator's arm back and forth. Has become a winner. Further, the lift-up type tailgate is heavy and troublesome to operate.
For this reason, there is a tendency for recent slide doors to be provided with a power slide device that can slide the doors in the opening and closing directions with motor power, and the tailgate is opened and closed with motor power. A power lift device may be provided.
In these power devices, there are a type in which a clutch mechanism for controlling the connection between a moving body such as a slide door and a tailgate and a motor is provided, and a type in which this is omitted.
[0003]
[Problems to be solved by the invention]
In the power device with a clutch mechanism, when the power device is activated, the clutch mechanism is connected and the motor power is transmitted to the moving body. When the power device is finished operating, the clutch mechanism is disconnected and the connection between the motor and the moving body is released. The As described above, the clutch mechanism is switched between the connected state and the disconnected state according to the operating state / non-operating state of the power device because it is desired to move the moving body easily without receiving excessive resistance even by manual operation. This is because there are user needs. However, a clutch mechanism for a power device that meets such needs is expensive, and if a clutch mechanism is added to the power device, control of the entire device becomes complicated.
On the other hand, in a power device without a clutch mechanism, since the motor and the moving body are always connected regardless of the operating state / non-operating state of the power device, it is difficult to manually move the moving body. However, significant cost savings and control simplification are provided.
[0004]
[Means for solving the problems]
Therefore, the present invention can adopt a very inexpensive clutch mechanism by switching the clutch mechanism between the connected state and the disconnected state based on the user's intention, and without complicating the control. The moving body can be moved according to the condition.
Therefore, the present invention is related to the movable body 11 composed of the sliding door 11A or the lift-up tailgate 11B of the vehicle, the motor 21, the speed reduction unit 22 that decelerates the output of the motor 21, and the movable body 11. And an output unit 24 that moves the moving body 11 with a deceleration output from the deceleration unit 22, and the power of the motor 7 provided between the deceleration unit 22 and the output unit 24 via the deceleration unit 22. A clutch mechanism 23 that switches between a connected state that can be transmitted to the output unit 24 and a disconnected state in which the power of the motor 7 is not transmitted by the output unit 24. The manual operation unit 25 is associated with the clutch mechanism 23. Therefore, the clutch mechanism 23 is switched from the connected state to the disconnected state or vice versa by the operation of the manual operating unit 25, and the clutch The connection state or the disconnection state after the switching of the switch mechanism 23 is obtained by said manual operating section 25 is mobile power device for a vehicle which is maintained until the re-operation.

【Example】
An embodiment of the present invention will be described with reference to the drawings. Reference numeral 10 denotes a vehicle body, 11A denotes a sliding door as the moving body 11, 12 denotes a door opening opened and closed by the sliding door 11A, and the vehicle body 10 near the upper portion of the door opening 12 has The upper rail 13 is fixed, the lower rail 14 is fixed to the vehicle body 10 near the lower portion of the door opening 12, and the center rail 16 is fixed to the quarter panel 15 that is the rear side surface of the vehicle body 10. The slide door 11A has an upper bracket 17 slidably engaged with the upper rail 13, a lower bracket 18 slidably engaged with the lower rail 14, and a center bracket 19 slidably engaged with the center rail 16. Provided. Each bracket 17, 18, 19 is preferably pivotally fixed to the slide door 11 </ b> A, and the slide door 11 </ b> A is slidable in the opening direction and the closing direction by the engagement of these brackets and the rail.
[0006]
A power device 20 including a motor 21 is provided in the internal space of the sliding door 11 </ b> A or the indoor space of the quarter panel 15 of the vehicle body 10. The output of the motor 21 is decelerated by the reduction unit 22 and transmitted to the output unit 24 via the clutch mechanism 23.
[0007]
The clutch mechanism 23 of the present invention is different from the conventional clutch mechanism, and is switched between a connected state and a disconnected state by operation of a manual operation unit 25 provided in the vehicle, and is independent of the output state of the motor 21. The connected state or disconnected state is maintained. The manual operation unit 25 is preferably composed of a switching lever or a switch contact. The clutch mechanism 23 may be simple and inexpensive, and there is no limitation on its configuration. For example, in the case of the mesh clutch type, the connection state is switched to the disconnection state or vice versa by the manual operation force of the switching lever or the separate motor power operated by the switch contact. Further, a clutch that inserts and removes the connecting pin with power such as a solenoid may be used.
[0008]
The output unit 24 is preferably composed of a wire drum, and the wire drum 24 has two wire cables connected to the slide door 11A, that is, the proximal end side of the opening cable 26 and the closing cable 27. When the wire drum 24 rotates in the door opening direction, the door opening cable 26 is wound up and the door closing cable 27 is fed out. When the wire drum 24 rotates in the door closing direction, the door opening cable 26 is pulled out. The closing door cable 27 is wound up, and the sliding door 11A slides in the opening direction and the closing direction by moving the cable.
In the above, a specific example of the moving body 11 has been described as the slide door 11A. However, in the present invention, the lift-up type tailgate 11B of the vehicle is also included in the object of the moving body 11.
[0010]
[Action]
When the moving body 11 is moved by the power of the power device 20, the manual operation unit 25 is operated to switch the clutch mechanism 23 to the connected state. In this state, when the power device 20 is activated, the power of the motor 21 is decelerated by the speed reduction unit 22 and then transmitted to the output unit 24 via the clutch mechanism 23. The operation of the output unit 24 causes the moving body 11 to move in a predetermined direction. When the movement is completed, the power device 20 returns to the standby state. The connection state of the clutch mechanism 23 is maintained until the manual operation unit 25 is (re) operated regardless of whether the power device 20 is activated or deactivated.
[0011]
When it is desired to move the moving body 11 manually, the manual operation unit 25 is (re) operated to switch the clutch mechanism 23 to the disconnected state. In this state, since the moving body 11 is completely separated from the speed reduction unit 22 of the power device 20, the moving body 11 can be moved manually and easily without receiving excessive resistance. Also, the disconnected state of the clutch mechanism 23, the manual operation section 25 is maintained until the re-operation.
[0012]
【The invention's effect】
As described above, according to the present invention, the power movement using the power device 20 and the manual movement can be switched based on the user's will, and the connected state and the disconnected state of the clutch mechanism 23 are determined by the power device. Regardless of whether the manual operation unit 25 is operated (re-) regardless of whether the power mechanism 20 is operated or not, the switching of the clutch mechanism 23 is independent of whether the power device 20 is operated or not. It is only necessary to simply connect / disconnect the unit 22 and the output unit 24, and therefore, an inexpensive unit can be used, and the switching is performed in a state completely independent of the control of the power device 20. The presence of 23 does not complicate the control of the power device 20.
