The manual drive unit 30 includes a drive shaft 31 having both ends extended in a direction intersecting the guide bar 222 and connected to the third gear 23 at one end thereof, (Not shown).

The drive shaft 31 is rotatably fixed to the base portion 230 between both ends, and the other end is positioned outside the base portion 230. Therefore, it can be understood that the other end of the drive shaft 31 passes through the base part 230 and is rotatably fixed to the base part 230 thereof.

The manual handle 32 is detachably coupled to the other end of the driving shaft 31 and is positioned outside the base 230 after the coupling. Here, the manual driving device 1 may be provided with a separate fastening means (not shown) for preventing the manual handle 32 from being separated easily after being coupled to the driving shaft 31.

The driving shaft 31 is rotated in conjunction with the driving of the automatic driving unit 220 to idle while rotating the manual shaft 32 in a state of emergency or power supply, .

That is, the manual handle 32 is separated from the drive shaft 31 when the rotational force is transmitted to the guide bar 222 by driving the motor 221 as shown in FIG. When the vehicle is in an emergency or in a state where power is not applied, the driving force is transmitted to the guide bar 22 by manual operation.

Alternatively, the drive shaft 31 may have a first drive shaft 31a having both ends and connected to the third gear 23 at one end thereof, and a second drive shaft 31a having one end thereof opposed to the other end of the first drive shaft 31a, And a second drive shaft 31b to which the manual handle 32 is detachably coupled. The manual drive unit 30 includes a coupling unit for coupling the first and second drive shafts 31a and 31b, 33).

The manual driving device 1 may further include a speed reducer 40 connected to the driving shaft 31. The manual driving device 1 may be connected to the second driving shaft 31b of the first and second driving shafts 31a and 31b .

The second drive shaft 31b is movably coupled to the speed reducer 40. The speed reducer 40 is capable of transmitting a rotational force transmitted to the guide bar 222 by a small force.

The coupling unit 33 keeps the first and second driving shafts 31a and 31b unclamped when the rotational force is transmitted to the guide bar 222 by driving the motor 221, And the first and second drive shafts 31a and 31b are held in a state where they are mutually coupled when the power is not applied.

The second drive shaft 31b is rotatably fixed between both ends of the guide bar 222. The second drive shaft 31b is rotatably supported by the second drive shaft 31b, A transfer bar 36 which is moved toward the first drive shaft 31a or moved together with the second drive shaft 31b in accordance with the release of the pressure is connected to both ends of the transfer bar 36, And a pair of conveying support bars 37 extending in a direction opposite to the position where the second drive shaft 31b is positioned and fixed to the base part 230 so as to be movable in the longitudinal direction.

5, when the second drive shaft 31b is pressed and released in the direction of the first drive shaft 31a, the coupling unit 33 is rotated so that the arm and the male couplings 34a and 34b are separated from each other (Not shown).

The pivoting means 38 may be a spring 38a of a general shape and may be coupled to the pair of conveying support bars 37 to be contracted and relaxed while being in contact with the base portion 230, (35) can be returned to the home position.

That is, the spring 38a is contracted as the manual handle 32 presses the other end of the second drive shaft 31b and the manual handle 32 is retracted from the second drive shaft 31b Relaxed as it separates.

When the pivoting unit 38 is contracted, the conveying unit 35 is moved in a direction in which the guide bar 222 is positioned, and the arm / male couplings 34a and 34b are engaged. Then, when the rotation means 35 is released, the transfer means 35 returns to the original position, and the arm / male couplings 34a and 34b are separated.

At this time, the passive driving device 1 includes a sensing sensor 40 for sensing a state where the arm and the male couplings 34a and 34b are engaged, And a controller 50 for controlling the motor 221 so that the motor 221 is not driven in a state where the first and second motors 34a and 34b are coupled to each other.

6, the detection sensor 40 senses a state where the male and female couplings 34a and 34b are separated and transmits the detection signal to the control unit 50, And drives the motor 221 according to a detection signal.

Alternatively, the detection sensor 40 senses the position of the transport bar 36 in a state where the arm and the male couplings 34a and 34b are coupled to transmit the detection signal to the controller 50, The control unit 50 may maintain the state in which the driving of the motor 221 is stopped according to the detection signal.

This is because electric power is transmitted to the motor 221 again while the rotational force is transmitted to the guide bar 22 by manual driving in a state where the driving of the motor 221 is temporarily stopped in an emergency or in a state where no electricity is applied It can be understood that it is intended to prevent a safety accident that may be caused by authorization.

1 to 6, the manual driving apparatus 1 according to the present invention is configured such that the satellite vehicle 100 is moved from a vertical state to a horizontal state When the driving of the motor 221 is stopped during the standing motion from the horizontal state to the vertical state, the manual handle 32 is coupled to the second driving shaft 31b, To be transmitted.

At this time, the guide bar 22 maintains the state in which the connection with the motor 221 is blocked while the clutch 11 is disconnected from the motor 221.

The male and male couplings 34a and 34b are coupled to each other by pushing and pushing the second drive shaft 31b while the manual handle 32 is coupled to the second drive shaft 31b, And the 1,2 drive shafts 31a and 31b are connected.

When the first and second drive shafts 31a and 31b are coupled, the detection sensor 50 transmits the detection signal to the controller 60 to disable the motor 221. At this time, it can be understood that the controller (60) blocks power from being applied to the motor (221).

The satellite 100 can assume a stable posture while being vertically adjusted from a vertical state to a horizontal state or from a horizontal state to a vertical state according to the rotation of the manual handle 32.

On the other hand, when the manual handle 32 is separated from the second drive shaft 31b, the arm and male couplings 34a and 34b are separated and the first and second drive shafts 31a and 31b are separated from the engaged state .

The rotational force of the motor 221 may be transmitted to the guide bar 222 while the clutch 11 is connected to the motor 221.

When the first and second drive shafts 31a and 31b are coupled, the detection sensor 50 transmits the detection signal to the controller 60 so that the motor 221 can be driven. At this time, the controller 60 can be understood as being powered by the motor 221.

Therefore, the manual driving device 1 can be operated by the trolley 200 such that the satellite 100 is moved from the vertical state to the horizontal state or from the horizontal state to the vertical state, The attitude of the satellite 100 can be manually adjusted stably when an emergency such as an interruption occurs.

The present invention is not limited to the above-described embodiment, but may be applied to other types of vehicles such as the following claims It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
