Hereinafter, the drive device of the present invention will be described with reference to the drawings.

Example 1
The drive device according to the first embodiment drives an opening / closing operation of a lid of a console box mounted on a vehicle. The functional body is a lid of the console box. The drive apparatus of Example 1 is an example provided with structure (1), (2), (3). FIG. 1 and FIGS. 3 to 9 are explanatory diagrams schematically showing the operation of the driving apparatus of the first embodiment. FIG. 2 shows an enlarged exploded perspective view schematically showing a main part of the driving apparatus of the first embodiment. FIG. 1 and FIG. 3 are main part enlarged explanatory views showing a state in which the urging force is accumulated in the driving means. 4 to 7 are enlarged views for explaining a main part showing that the functional body is driven by the urging force accumulated in the driving means. FIG. 8 and FIG. 9 are main part enlarged explanatory views showing a state in which the functional body is driven manually. Hereinafter, clockwise and counterclockwise refer to clockwise and counterclockwise in FIG.

  The driving apparatus according to the first embodiment includes an input unit 1 and a driving unit 2. As shown in FIGS. 1 and 2, the input unit 1 includes a weight body 10, a connecting rod 11, and a pivot shaft 12. A pivot portion is constituted by the connecting rod 11 and the pivot shaft portion 12. The connecting rod 11 is formed in a rod shape. One end of the connecting rod 11 is enormous and forms the weight body 10. A pivot shaft 12 is formed at the other end of the connecting rod 11. Protruding coupling shafts 13 are formed on the front and back surfaces of the pivot shaft 12, respectively. One connecting shaft 13 is attached to the side wall of the console box 8. The input unit 1 swings around the pivot shaft 12 in accordance with the acceleration derived from the traveling operation of the vehicle. One end of an elastic body 14 made of a coil spring is attached to the connecting rod 11. The other end of the elastic body 14 is attached to the end side wall of the console box 8. The elastic body 14 balances the input means 1. The input means 1 swings around the pivot shaft 12 in two directions, clockwise and counterclockwise. A driving means 2 is connected to the input means 1.

  The drive means 2 has an input connecting member 3, a spring motor 4, a drive gear 5, a connection gear member 6, and a driven gear 7.

  As shown in FIG. 2, the spring motor 4 has a spring shape in which a long metal plate is wound counterclockwise. The spring motor 4 is housed in a hollow interior formed between the drive gear 5 and the winding gear 30. The drive gear 5 is formed in a box shape. The hoisting gear 30 is formed in a box shape, and is arranged coaxially with the driving gear 5 with the inner surface of the box facing the inner surface of the driving gear 5. The outer end 40 of the spring motor 4 is connected to the inner peripheral surface of the drive gear 5. An inner end 41 of the spring motor 4 is fixed to the winding gear 30. The spring motor 4, the drive gear 5, and the winding gear 30 have a so-called barrel shape. A portion of the spring motor 4 on the outer end 40 side is reversely wound in an S shape. The outer end 40 is bent outward. The outer end 40 is in pressure contact with a recess 50 formed on the inner peripheral surface of the drive gear 5. When the spring motor 4 is wound up, the outer shape of the spring motor 4 is reduced, and the pressing force with which the outer end 40 presses the surface of the recess 50 is reduced. When the spring motor 4 is excessively wound, the pressing force of the outer end 40 becomes too small, and the outer end 40 slides on the surface of the recess 50. Therefore, an excessive load due to winding is not applied to the spring motor 4.

  The drive gear 5 and the winding gear 30 are pivotally supported on the side wall of the console box 8. An oil damper 80 is connected to the drive gear 5. An anti-reverse gear 81 made up of a one-way clutch is connected to the winding gear 30.

  The input connecting member 3 includes a lower movement transmission unit 31, an upper movement transmission unit 32, and a winding gear 30. As shown in FIG. 2, the lower movement transmission unit 31 includes two gears, and the upper movement transmission unit 32 includes three gears. The lower movement transmission gear 35, which is one of the gears of the lower movement transmission unit 31, is composed of a one-way clutch. The lower motion transmission gear 35 is connected to one connecting shaft 13 of the pivot shaft 12. Then, the counterclockwise swing of the input means 1 is transmitted and the clockwise swing is blocked. Therefore, as shown in FIG. 1, when the input means 1 swings counterclockwise, the downward movement transmission gear 35 rotates counterclockwise. When the input means 1 swings clockwise, the lower movement transmission gear 35 does not rotate. The lower movement communication gear 36, which is the other gear of the lower movement transmission unit 31, meshes with the lower movement transmission gear 35. When the lower movement transmission gear 35 rotates counterclockwise, the lower movement communication gear 36 rotates clockwise. The lower movement communication gear 36 meshes with the winding gear 30. When the downward movement communication gear 36 rotates clockwise, the winding gear 30 rotates counterclockwise. That is, when the input means 1 swings counterclockwise, the lower movement transmission gear 35 rotates counterclockwise, the lower movement communication gear 36 rotates clockwise, and the winding gear 30 rotates counterclockwise. The spring motor 4 is wound up.

  The upper movement transmission gear 37, which is one gear of the upper movement transmission section 32, is composed of a one-way clutch. The upper motion transmission gear 37 is connected to the other connecting shaft 13 of the pivot shaft 12. Then, the clockwise swing of the input means 1 is transmitted and the counterclockwise swing is blocked. Therefore, as shown in FIG. 3, when the input means 1 swings clockwise, the upward movement transmission gear 37 rotates clockwise. When the input means 1 swings counterclockwise, the upward movement transmission gear 37 does not rotate. The upper movement first connection gear 38 that is the second gear of the upper movement transmission unit 32 rotates counterclockwise when the upper movement transmission gear 37 rotates clockwise. The first moving first connecting gear 38 is meshed with the second moving second connecting gear 39 that is the third gear of the upper moving transmitting portion 32. When the upward movement first connection gear 38 rotates counterclockwise, the upward movement second connection gear 39 rotates clockwise. The upward moving second communication gear 39 is engaged with the winding gear 30. When the upward moving second connection gear 39 rotates clockwise, the winding gear 30 rotates counterclockwise. That is, when the input means 1 swings clockwise, the upward movement transmission gear 37 rotates clockwise, the upward movement first connection gear 38 rotates counterclockwise, and the upward movement second connection gear 39 rotates clockwise. , The winding gear 30 rotates counterclockwise, and the spring motor 4 is wound up.

  The functional body 9 opens and closes an opening formed in the upper surface of the console box 8 main body. The functional body 9 is pivotally supported on the side wall of the console box 8 and rotates with respect to the console box 8. The driven gear 7 has a fan shape and is coaxially connected to the functional body 9. The functional body 9 rotates clockwise and counterclockwise.

  The connection gear member 6 includes a flat support plate 60, a first connection gear 61, a second connection gear 62, a third connection gear 63, and a fourth connection gear 64. The first connection gear 61, the second connection gear 62, the third connection gear 63 and the fourth connection gear 64 are pivotally supported on the support plate 60. The support plate 60 is pivotally supported on the side wall of the console box 8. The first connection gear 61 meshes with the drive gear 5. The rotation shaft of the first connection gear 61 is coaxial with the swing shaft of the support plate 60. The second connection gear 62 meshes with the first connection gear 61. The third connection gear 63 meshes with the first connection gear 61. The fourth connection gear 64 meshes with the third connection gear 63. The support plate 60 has a reverse connection position (shown in FIGS. 1, 3, 4, 7, and 9) where the fourth connection gear 64 meshes with the driven gear 7, and a normal connection where the second connection gear 62 meshes with the driven gear 7. Swings between positions (shown in FIGS. 5, 6 and 8). One end of a turnover spring 65 is fixed to the support plate 60. The other end of the turnover spring 65 is fixed to the side wall of the console box 8. Therefore, the connection gear member 6 is biased to the normal connection position and the reverse connection position by the turnover spring 65. A gear group composed of the first connection gear 61 and the second connection gear 62 is referred to as a first connection gear group. A gear group composed of the first connection gear 61, the third connection gear 63, and the fourth connection gear 64 is referred to as a second connection gear group.

  The connection gear member 6 is connected to switch means (not shown). When the switch means is turned on, the connection gear member 6 swings and is arranged at the normal connection position. When the switch means is turned off, the connection gear member 6 swings and is placed at the reverse connection position.

  A first stopper 85 protruding in the direction of the driven gear 7 is formed on the side of the console box 8 on the pivot shaft side of the functional body 9. A second stopper 86 protruding in the direction of the driven gear 7 is formed on the side wall of the console box 8 below the first stopper 85. The first stopper 85 engages with the driven gear 7 when the functional body 9 is disposed at an open position (shown in FIGS. 6 and 7) that opens the opening of the console box 8. The second stopper 86 engages with the driven gear 7 when the functional body 9 is disposed at a closed position (shown in FIGS. 1, 3, 4, and 5) that closes the opening of the console box 8.

  The operation of the driving apparatus of Embodiment 1 will be described below.

  When the urging force is accumulated in the spring motor 4, the drive gear 5 rotates counterclockwise. As shown in FIG. 4, when the functional body 9 is disposed at the closed position and the connection gear member 6 is disposed at the reverse connection position, the drive gear 5 and the driven gear 7 are connected by the second connection gear group. . When the drive gear 5 rotates counterclockwise due to the biasing force of the spring motor 4, the first connection gear 61 rotates clockwise, the third connection gear 63 rotates counterclockwise, and the fourth connection gear 64 rotates clockwise. Rotate around. Therefore, the driven gear 7 that meshes with the fourth connection gear 64 rotates counterclockwise. When the driven gear 7 rotates counterclockwise, the functional body 9 integrated with the driven gear 7 rotates counterclockwise to close the opening of the console box 8. When the functional unit 9 is rotated to the closed position, the driven gear 7 and the second stopper 86 are engaged, and the rotation of the driven gear 7 and the rotation of the functional unit 9 are stopped.

  Note that a reverse rotation preventing gear 81 is connected to the winding gear 30. For this reason, the winding gear 30 does not rotate clockwise. Therefore, the drive gear 5 rotates counterclockwise by the biasing force of the spring motor 4. Further, an oil damper 80 is connected to the drive gear 5. For this reason, the drive gear 5 rotates gently, and the functional body 9 opens and closes gently.

  When the switch means is turned on in the state shown in FIG. 4 (the function body 9 is disposed at the closed position and the connection gear member 6 is disposed at the reverse connection position), the connection gear member 6 swings counterclockwise. And placed in the positive connection position. At this time, the drive gear 5 and the driven gear 7 are connected by the first connection gear group as shown in FIG. When the drive gear 5 member rotates counterclockwise by the biasing force of the spring motor 4, the first connection gear 61 rotates clockwise and the second connection gear 62 rotates counterclockwise as shown in FIG. . Therefore, the driven gear 7 meshing with the second connection gear 62 rotates clockwise. When the driven gear 7 rotates clockwise, the functional body 9 rotates clockwise and opens the console box 8. When the functional unit 9 is rotated to the open position, the driven gear 7 and the first stopper 85 are engaged, and the rotation of the driven gear 7 and the rotation of the functional unit 9 are stopped.

  When the switch means is turned off in the state shown in FIG. 6 (the functional body 9 is disposed at the open position and the connection gear member 6 is disposed at the normal connection position), the connection gear member 6 swings clockwise. And placed in the reverse connection position. At this time, the drive gear 5 and the driven gear 7 are connected by the second connection gear group as shown in FIG. When the drive gear 5 rotates counterclockwise by the biasing force of the spring motor 4, as shown in FIG. 7, the first connection gear 61 rotates clockwise, and the third connection gear 63 rotates counterclockwise. The fourth connection gear 64 rotates clockwise. Therefore, the driven gear 7 meshing with the fourth connection gear 64 rotates counterclockwise. Then, the function body 9 rotates counterclockwise to close the console box 8 (FIG. 4).

  In the driving apparatus according to the first embodiment, the input unit 1 swings around the pivot shaft 12 in accordance with the acceleration derived from the traveling operation of the vehicle. For example, when the vehicle accelerates, decelerates, vibrates, changes direction, etc., the input means 1 swings according to the acceleration generated from the traveling operation. Then, the driving force is accumulated in the spring motor 4 of the driving means 2 following the swing of the input means 1, and the functional body 9 is driven by the driving force accumulated in the driving means 2. Since the functional unit 9 is driven by the driving force accumulated in advance, the functional unit 9 can be driven even when the input unit 1 is not moving. In addition, the input unit 1 does not use a battery as a power source because the input unit 1 swings according to the acceleration derived from the traveling operation of the vehicle.

  In the driving apparatus according to the first embodiment, the spring motor 4 is used as a driving source, so that the cost required for the material is reduced. Therefore, the drive device of Example 1 can be manufactured at low cost.

  Further, the connection gear member 6 takes two positions, a normal connection position and a reverse connection position. For this reason, the driven gear 7 can be rotated in both directions by rotation of the drive gear 5 in one direction. Therefore, both the opening operation and the closing operation of the functional body 9 can be driven by the urging force of the spring motor 4.

  On the other hand, when the function body 9 is manually rotated counterclockwise in the state shown in FIG. 6 (the function body 9 is disposed in the open position and the connection gear member 6 is disposed in the normal connection position) As shown in FIG. 8, the driven gear 7 rotates counterclockwise. Then, the second connection gear 62 meshing with the driven gear 7 rotates clockwise, and the first connection gear 61 rotates counterclockwise. The drive gear 5 meshed with the first connection gear 61 rotates clockwise. For this reason, the spring motor 4 is wound up, and the urging force is accumulated in the spring motor 4.

  Further, when the function body 9 is manually rotated clockwise in the state shown in FIG. 4 (the function body 9 is disposed in the closed position and the connection gear member 6 is disposed in the reverse connection position), FIG. As shown in FIG. 9, the driven gear 7 rotates clockwise. Then, the fourth connection gear 64 meshed with the driven gear 7 rotates counterclockwise, the third connection gear 63 rotates clockwise, and the first connection gear 61 rotates counterclockwise. The drive gear 5 meshed with the first connection gear 61 rotates clockwise. Therefore, also in this case, the spring motor 4 is wound up, and the urging force is accumulated in the spring motor 4.

  Thus, in the drive device of the present embodiment, the functional body 9 constitutes the second input means. For this reason, when the function body 9 is manually opened or closed, the spring motor 4 is wound up, and the urging force can be accumulated in the spring motor 4. Further, the functional body 9 can be automatically opened or closed by the biasing force accumulated by manually opening and closing the functional body 9.

  In the driving apparatus of the first embodiment, the movement of the input unit 1 is transmitted to the driving unit 2 through a gear. However, another unit such as a wire may be used instead of the gear. For example, one end of the wire may be fixed to the weight body 10 of the input unit 1, the other end may be fixed to a slidable rack, and the lower movement transmission gear 35 and the upper movement transmission gear 37 may be engaged with the rack. In this case, when the input unit 1 swings, the wire is pulled, the rack fixed to the wire slides, and the upper motion transmission gear 37 and the lower motion transmission gear 35 engaged with the rack rotate. The spring motor 4 can be wound up by rotating the winding gear 30 by the rotation of the upper movement transmission gear 37 and the lower movement transmission gear 35.

  In the driving device of the embodiment, the rotation of the functional body 9 is driven, but the linear motion of the functional body 9 can also be driven. For example, by providing a rack that meshes with the driven gear 7 of the functional body 9, the rotation of the driven gear 7 can be converted into a linear motion, and the linear motion of the functional body 9 can be driven.

  In the driving device of the embodiment, the spring motor 4 is wound up by the movement of the input means 1 in both directions, but the spring motor 4 may be wound up by only one movement. In this case, the input gear may be a one-way clutch and the input gear and the hoisting gear 30 may be directly meshed.

  In the driving device of the embodiment, a spring is used as the spring motor 4, but another spring motor such as a coil spring may be used. An electric motor may be used instead of the spring motor. In this case, if the input gear and the electric motor are connected, the electric motor can be rotated by the movement of the input means 1 as in the first embodiment. And it can generate electric power by rotation of this electric motor. If electricity storage means such as a capacitor is connected to the electric motor, electricity generated by the electric motor can be stored. If the electric motor and the drive gear 5 are connected, the functional body 9 can be driven by rotating the electric motor with the stored electric power.

  In the drive device of the present invention, the mechanism for causing the drive means 2 to follow the movement of the input means 1 is not limited to the above-described mechanism. Further, the mechanism for driving the functional body 9 with the driving force accumulated in the driving means 2 is not limited to the mechanism of the embodiment.

(Example 2)
The drive apparatus of Example 2 is an example provided with structure (1), (2), (4). Specifically, the driving apparatus of the second embodiment is the same as that of the first embodiment except for the input unit and the input connecting member. FIG. 10 and FIG. 12 schematically illustrate how the urging force is accumulated in the spring motor in the driving device of the second embodiment. FIG. 11 is an enlarged exploded perspective view schematically showing a main part of the driving apparatus according to the second embodiment. Hereinafter, clockwise and counterclockwise refer to clockwise and counterclockwise in FIG.

An elastic member 15 made of a coil spring is fixed to one end of the weight body 10 in the longitudinal direction. The other end of the elastic member 15 is fixed to the end side wall of the console box 8. On the end side wall of the console box 8, a groove portion 80 extending in the vertical direction is formed. The weight body 10 is disposed in the groove 80 with its longitudinal direction facing up and down, and is suspended by the elastic member 15. The input means 1 moves up and down according to the acceleration derived from the traveling operation of the vehicle. The groove 80 interferes with movements other than the vertical movement of the weight body 10.

  A connecting gear 34 is connected to the rack of the weight body 10. The connection gear 34 meshes with the rack of the weight body 10 and is pivotally supported on the side wall of the console box 8. The shaft center of the connecting gear 34 forms a connecting shaft 13 that extends in a protruding shape. In the drive device according to the second embodiment, the input connecting member 3 includes a connecting gear 34, a lower movement transmission unit 31, an upper movement transmission unit 32, and a winding gear 30.

The lower movement transmission gear 35, which is one of the gears of the lower movement transmission unit 31, is composed of a one-way clutch. The lower motion transmission gear 35 is connected to one connecting shaft 13 of the connecting gear 34. Then, the counterclockwise rotation of the connection gear 34 is transmitted, and the clockwise rotation is blocked. Therefore, as shown in FIG. 10, when the connecting gear 34 rotates counterclockwise, the downward movement transmission gear 35 rotates counterclockwise. When the connection gear 34 rotates clockwise, the lower movement transmission gear 35 does not rotate. The lower movement communication gear 36, which is the other gear of the lower movement transmission unit 31, meshes with the lower movement transmission gear 35. When the lower movement transmission gear 35 rotates counterclockwise, the lower movement communication gear 36 rotates clockwise. The lower movement communication gear 36 meshes with the winding gear 30. When the downward movement communication gear 36 rotates clockwise, the winding gear 30 rotates counterclockwise. That is, when the input means 1 moves downward and the coupling gear 34 swings counterclockwise, the lower motion transmission gear 35 rotates counterclockwise, the lower motion communication gear 36 rotates clockwise, and the winding gear 30 Rotates counterclockwise and the spring motor 4 is wound up.

  The upper movement transmission gear 37, which is one gear of the upper movement transmission section 32, is composed of a one-way clutch. The upper motion transmission gear 37 is connected to the other connecting shaft 13 of the connecting gear 34. Then, the clockwise rotation of the connection gear 34 is transmitted, and the counterclockwise rotation is blocked. Therefore, as shown in FIG. 12, when the connecting gear 34 rotates clockwise, the upward movement transmission gear 37 rotates clockwise. When the connection gear 34 rotates counterclockwise, the upper motion transmission gear 37 does not rotate. The upper movement first connection gear 38 that is the second gear of the upper movement transmission unit 32 rotates counterclockwise when the upper movement transmission gear 37 rotates clockwise. The first moving first connecting gear 38 is meshed with the second moving second connecting gear 39 that is the third gear of the upper moving transmitting portion 32. When the upward movement first connection gear 38 rotates counterclockwise, the upward movement second connection gear 39 rotates clockwise. The upward moving second communication gear 39 is engaged with the winding gear 30. When the upward moving second connection gear 39 rotates clockwise, the winding gear 30 rotates counterclockwise. That is, when the input means 1 moves upward, the coupling gear 34 rotates clockwise, the upper motion transmission gear 37 rotates clockwise, the upper motion first connection gear 38 rotates counterclockwise, and the upper motion first 2 The connection gear 39 rotates clockwise, the winding gear 30 rotates counterclockwise, and the spring motor 4 is wound up.

  In the driving apparatus according to the second embodiment, the input unit 1 moves up and down according to the acceleration derived from the traveling operation of the vehicle. Then, the driving force is accumulated in the spring motor 4 of the driving means 2 following the vertical movement of the input means 1, and the functional body 9 is driven by the driving force accumulated in the driving means 2. Similarly to the driving device of the first embodiment, the driving device of the second embodiment drives the functional body 9 with the driving force accumulated in advance, and therefore can drive the functional body 9 even when the input unit 1 is not moving. . In addition, the input unit 1 does not use a battery as a power source because the input unit 1 swings according to the acceleration derived from the traveling operation of the vehicle.

  In the driving apparatus according to the second embodiment, the spring motor 4 is used as a driving source, so that the cost required for the material is reduced. Therefore, the drive device according to the second embodiment can be manufactured at a low cost like the drive device according to the first embodiment.
