Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control cable with a solenoid.
More specifically, the present invention relates to a solenoid-equipped control cable for unlocking various mechanical devices.

[Prior Art] As a conventional unlocking device using a control cable as an output member, there are automotive openers disclosed in, for example, Japanese Utility Model Publication No. 60-135457 and Japanese Utility Model Publication No. 61-129075. Example I). In this conventional example I, two inner cables are wound and driven by one electric motor. The forward rotation of the electric motor can unlock the fuel lid, and the reverse rotation can rotate the trunk lid or the trunk lid. The back door can be unlocked.

As another conventional unlocking device (hereinafter referred to as Conventional Example II), two solenoids (70) and (71) are used as shown in FIG.
Connect the inner cable for operation to the movable iron cores of (0) and (71), and use one solenoid (70) to connect the fuel lid (72).
There is one in which the lock of the trunk lid (73) or the back door is unlocked by the other solenoid (71).

[Problems to be Solved by the Invention] In the case of the above-mentioned conventional example I, since the speed reducer and the winding drum must be assembled to the electric motor, the device becomes large, and the degree of freedom in selection when assembling is increased. There is a problem of becoming low.

Further, in the case of the conventional example II, since two solenoids have to be used, there is a problem that the installation place is large and the weight is heavy. For example, 2 solenoids
When used individually, the solenoid alone weighs about 300 g, and therefore weighs about 600 g without the cable.

Therefore, an object of the present invention is to provide a compact and lightweight control cable with a solenoid.

[Means for Solving Problems] The control cable with a solenoid of the first invention is
(A) It has one movable iron core and a first coil and a second coil arranged along the moving direction of the movable iron core, and when one coil is excited, the movable iron core is attracted in one direction. A solenoid capable of attracting the movable iron core in the opposite direction when the other coil is excited, and (b) at least two inner cables connected to both ends of the movable iron core, respectively.
The movable iron core has a cavity therein having a length corresponding to a moving stroke of the movable iron core, and a nipple fixed to the ends of the two inner cables is loosely fitted in the cavity. Characterize.

The control cable with the solenoid of the second invention is
(A) It has one movable iron core and a first coil and a second coil arranged along the moving direction of the movable iron core, and when one coil is excited, the movable iron core is attracted in one direction. A solenoid capable of attracting the movable iron core in the opposite direction when the other coil is excited; and (b) at least one inner cable connected to one end of the movable iron core and the other end of the movable iron core. The movable iron core has a cavity having a length corresponding to the moving stroke of the movable iron core, and a nipple fixed to the end of the inner cable is loosely fitted in the cavity. It is characterized by being done.

[Operation] In the first invention, the direction in which the movable iron core is attracted can be changed by exciting the first coil or the second coil. Therefore, for example, when the first coil is excited, the movable iron core is pulled in one direction and the pulling operation force can be output via one inner cable. In this case, since the nipple fixed to the end of the other inner cable moves inside the cavity of the movable iron core, the movement of the movable iron core is not transmitted to this inner cable.
When the second coil is excited, the movable iron core is pulled in the other direction and the pulling operation force can be output via the other inner cable. In this case, since the nipple fixed to the end of the one inner cable moves inside the cavity of the movable iron core, the movement of the movable iron core is not transmitted to this inner cable.

Similarly, in the second invention, the pulling operation force can be output by one inner cable or the other rod.

As described above, the present invention has two inner cables or an inner cable and a rod as an output member, but requires only one movable iron core. Therefore, the size is compact and lightweight, and the degree of freedom in selecting a mounting location is increased. It can contribute to the weight reduction of the device.
