The present invention relates to an electric control device for electrically operating a saddle angle of a bicycle and an electric saddle angle control device having a structure optimized for adjusting a saddle angle by an electric motor.

1 and 3, the electric saddle angle adjusting device 1 according to the present invention comprises saddle angle adjusting means 2, saddle angle adjusting means 2 (3) for electrically operating the electric motor (3).

The electromotive operation device 3 of the present invention is provided with moving force applying means for applying a force (a moving force or a releasing force) for shifting or changing the saddle angle adjusting means 2 between an angle fixed state and an angle adjustable state A power supply control unit 6 for controlling power supply from the power supply means 5 to the moving force application means 4, ).

The saddle angle adjusting means 2 includes an angle fixing means 21 for fixing the angle of the saddle, an angle adjusting plate 22 (angle adjusting means) for adjusting the angle of the saddle by being combined with the angle fixing means 21, Shaped saddle support 23 for supporting the saddle.

The angle fixing means 21 is a metal plate having a thickness enough to withstand the pressure applied to the saddle, and is provided so as to be movable up and down on the saddle support 23, as shown in Fig. 1 (b). The upper end portion (211) of the angle fixing means (21) is engaged with the angle regulating plate (22) to fix the angle of the saddle.

The angle regulating plates 22 are formed symmetrically with respect to each other with the saddle support 23 therebetween, and are integrally formed with the saddle support 23, but the present invention is not limited thereto. The angle regulating plate 22 is formed with a plurality of engaging grooves 221 which engage with the engaging portions 211 of the angle fixing means 21. [ In this embodiment, the angle regulating plate 22 has six engagement grooves 221 (see FIG. 2 (b)), but the number of the engagement grooves 221 can be appropriately selected in accordance with the angle adjustment range of the saddle.

A guide groove 231 for guiding the movement of the angle fixing means 21 is formed in the saddle support 23 in a direction parallel to the saddle support 23. The angle fixing means 21 has both lateral ends of the angle fixing means 21 protruded from the guide grooves 231 of the saddle support 23 so as to be able to engage with the angle adjusting plates 22 provided on both sides of the saddle support 23 do.

The saddle angle adjusting means 2 further includes a saddle anchor 24 for fixing the lower rail A-1 of the bicycle saddle. The saddle holding part 24 includes a saddle holding plate 241 that can be screwed with a lower rail of a bicycle saddle therebetween. The saddle holding plate 241 is provided with a first saddle holding groove 242 Is formed. As shown in Fig. 1, by using the angle regulating plate 22 as one fixing plate, the saddle angle regulating means 2 can be made more compact.

That is, in this embodiment, the second saddle-fixing groove 222 is formed in the angle regulating plate 22 and the lower rail A-1 of the bicycle saddle is interposed between the first saddle-fixing grooves 242 of the saddle- The lower rail of the saddle can be fixed to the saddle angle adjusting means 2 or the saddle support 23 by engaging the saddle holding plate 241 and the angle adjusting plate 22 with screws in a state in which the saddle holding plate 241 is accommodated. The second saddle holding groove 222 formed in the angle adjusting plate 22 is formed at a height between the upper end of the saddle support 23 and the mating groove 221 of the angle adjusting plate 22, It is more preferable to form it adjacent to the engaging groove 221 so as to be able to obscure as much as possible.

Hereinafter, the principle of adjusting the angle of the bicycle saddle with the saddle angle adjusting means 2 will be described with reference to Figs. 1 and 2. Fig.

The saddle of the bicycle is inserted into the engagement groove 221 of the angle regulating plate 22 (that is, the angle fixing means is moved to the angle fixing position) by inserting the engagement portion 211 of the angle fixing means 21 into the engagement groove 221 (An angle fixed state). When the engaging portion 211 of the angle fixing means 21 is pulled downward from the engaging groove 221 (that is, when the angle fixing means is moved to the retracted position or the retracted position), the angle regulating plate 22 is freely rotatable (Angle adjustable state). When the saddle angle adjusting means 2 is in the angle adjustable state (that is, when the angle fixing means is in the fixed release position), the saddle fixed by the saddle fixing portion 24 and the angle adjusting plate 22, (22).

That is, in the state in which the saddle angle adjusting means 2 is in the angle adjustable state (i.e., the state in which the angle fixing means is in the fixed release position), the angle adjusting plate 22 is rotated to the desired angular position, The angle of the saddle can be fixed at an angle determined by the position of the engaging groove 221 by inserting the engaging portion 211 of the means 21 into the engaging groove 221 corresponding to the angular position. This allows the user to adjust the angle of the bicycle saddle to the desired angle.

When the angle fixing means 21 is inserted into one of the engaging grooves 221 in the vicinity of the center of the plurality of engaging grooves 221, the saddle is horizontally fixed, When the angle fixing means 21 is inserted into the engaging groove 221 located at the rear side of the saddle, the saddle is bent forward. As a result, the user can support the drag force of the bike pedal during the uphill slope. On the other hand, when the angle fixing means 21 is coupled to the engaging groove 221 on the rear side of the engaging groove 221 which horizontally makes the saddle, the front side of the saddle is lifted and stable running is possible on the downhill road . The angular range in which the saddle is forward and the angle in which the front of the saddle is lifted can be adjusted depending on which of the engaging grooves is horizontally disposed. Further, by changing the distances between the engagement grooves, the angle changing units may be different from each other. For example, the distance between the coupling grooves near the center can be shortened, and the distance between the coupling grooves at both ends can be made long.

It is desirable that a force applied to the saddle in the direction of the bicycle handle is applied by a torsion spring (not shown). 2 (a), elastic means 25 (fixing force application means) is provided at the upper center portion of the angle fixing means 21 and the other end of the elastic means 25 is fixed to the saddle support 23 Connect. When the angle fixing means 21 moves downward from the angle fixing position to the fixing release position, the elastic means 25 is stretched, and the elastic restoring force acts in the direction of pulling up the angle fixing means 21 to the angle fixing position . In this case, the force applying means 4 provides a force (releasing force) for moving the angle fixing means 21 from the angle fixing position to the fixing releasing position, and the angle fixing means 21 is fixed from the fixing releasing position to the angle fixing The force (fixation force) to move to the position is provided by the elastic means 25. That is, when the force (release force) for holding the angle fixing means 21 in the fixed release position is not applied, the angle fixing means 21 moves to the angle fixing position by the elastic restoring force of the elastic means 25 do. In this embodiment, the elastic means 25 uses a spring, but is not limited thereto.

In the present invention, as the saddle-angle adjusting means (2), an embodiment using plate-like angle fixing means (21) having a constant thickness and two angle adjusting plates (22) having a plurality of engaging grooves having a size corresponding to the thickness However, other structures may be used as long as they are capable of combining and releasing each other.

As shown in Fig. 2 (b), on the outer side of the engaging groove 221 at both ends of the angle regulating plate 22, there are formed protrusions 223 (first protrusions) A protrusion 224 (second protrusion) is formed. The second projection 224 is formed to be longer than the distance that the angle fixing means 21 reciprocates between the angle fixing position and the retracting position (evacuation position), so that the angle fixing means 21 is prevented from escaping the angle adjusting plate 22 prevent. This makes it possible to prevent the angle of the saddle from being inclined out of a given range even when the user erroneously operates the electric operation device for moving the angle fixing means, as will be described later.

The engagement between the engaging portion 211 of the angle fixing means 21 and the engaging groove 221 of the angle regulating plate 22 should not be released even if the weight of the user is applied to the front side of the saddle at the angle fixed state, It is desirable to have a shape capable of releasing the lock by a force exerted by the solenoid of the operating device or the electric motor.

Specifically, the engaging portion of the angle fixing means 21 has a shape in which its side surface narrows toward the top of the upper side. That is, the handle-side main surface of the engaging portion 211 of the angle fixing means 21 is a plane parallel to the moving direction of the angle fixing means 21, and the main rear surface of the bicycle is in the moving direction of the angle fixing means 21 As shown in Fig. The engaging groove 221 has a shape corresponding to the shape of the engaging portion 211 of the angle fixing means 21. With this shape, the handle-side main surface (vertical surface) of the engaging portion 211 and the handle side wall (vertical wall) of the engaging groove 221 come into contact with each other even if the user's body weight or more force is applied to the front of the saddle It is possible to prevent the coupling from being undesirably released. On the other hand, since the engaging portion 211 is narrowed toward the front end, the engaging portion 211 can be pulled out from the engaging groove 221 by a small vertical force (moving force).

On both sides of the angle fixing means 21, protruding grip portions 212 and / or concave grip portions 213 are formed. The protruding grip portion 212 or the concave grip portion 213 can be gripped and moved by the user even when the power of the power supply means such as a battery to be described later is consumed and the angle fixing means 21 can not be moved by the motor It is. This allows the user to adjust the saddle of the bicycle to a desired angle even when the power of the power supply means (battery) of the electric control apparatus described later is consumed.

Hereinafter, the electric control device 3 of the present invention will be described in detail.

&Lt; Example 1 >

3 shows a moving force applying means 4 for applying a moving force (releasing force) for moving the angle fixing means 21 from the angle fixing position to the fixing releasing position. The moving force applying means 4 applies an electromagnetic moving force (releasing force) which is connected to the lower end portion of the angle fixing means 21 and pulls down the angle fixing means 21 downward, Respectively.

In this embodiment, the moving force applying means 4 includes a solenoid 41 that enables linear motion using electromagnetic induction. That is, in this embodiment, the force application means 4 is a hollow cylindrical structure formed by winding wires in the form of a coil at a fine pitch. The plunger (iron core) is held by a magnetic induction phenomenon generated when current is supplied to the coil (Releasing force) for releasing or releasing the angle fixing means 21 from the angle regulating plate 22 by applying the pulling force. In this embodiment, a wire is connected to one end of the plunger of the solenoid 41 as the moving force applying means 4, and the other end of the wire is connected to the hole at the lower end of the angle fixing means 21. [ Accordingly, when a current is supplied to the solenoid 41 and the plunger is pulled by the magnetic induction phenomenon, the angle fixing means 21 connected to the solenoid 41 through the wire is pulled downward and separated from the angle regulating plate 22 . In this embodiment, the solenoid 41 and the angle fixing means 21 are connected through a wire, but the present invention is not limited thereto, and one end of the plunger of the solenoid 41 may be directly connected to the angle fixing means 21 .

The moving force applying means 4 is provided for moving the angle fixing means 21 from the angular fixing position to the fixing position so as to overcome the elastic restoring force of the elastic means 25 (fixing force applying means) (Release force). The moving force (releasing force) provided by the moving force applying means 4 is adjustable by the number of turns of the coil of the solenoid 41 or the amount of current flowing through the coil. Considering that the moving force application means 4 is installed in the saddle support 23 and that the weight of the battery (power supply means) may be increased when the amount of current is to be increased, It is more preferable to make the elastic modulus of the elastic means 25 relatively small rather than increase the moving force (release force) by the elastic means 25 (4). However, the elastic means 25 should have a modulus of elasticity not to be released from the state of engagement or fixation with the angle regulating plate 22 due to the self weight of the angle fixing means 21. [

Power supply means 5 such as a battery is electrically connected to the moving force applying means 4. The power supply means 5 may be a primary battery, a secondary battery, or the like, but it is preferable to use a secondary battery because it is possible to recharge it. For example, it is preferable that a plurality of secondary batteries are connected in series to constitute a secondary battery module having a voltage capable of providing a necessary moving force (releasing force) such as 12V to 24V. The power supply means 5 is preferably installed on the saddle support 23, but may be installed on the frame of the bicycle main body to which the saddle support is connected.

The power supply control unit 6 controls on / off the power supply between the moving force application means 4 and the power supply means 5. The power supply control unit 6 includes a switch connected by wire between the moving force application means 4 and the power supply means 5, and the switch is installed on the handle of the bicycle. The user of the bicycle can operate the saddle-stitch angle adjusting device 2 only by a simple operation of pressing the switch provided on the bicycle handle. This makes it possible to safely operate the saddle angle regulating device 2 while minimizing the influence on the operation of the brake operation lever or the gear shift operation device provided on the handle of the bicycle.

The power control unit 6 may also be capable of wirelessly controlling power supply on / off. In this case, the power control unit 6 may include a transmitter for wirelessly transmitting the power supply signal and a receiver for receiving the power supply signal. In the case of wirelessly controlling the power supply, the transmitter is installed on the handle of the bicycle, and the receiver and the switch for receiving the power supply signal and turning on / off the switch are connected to the saddle support 23 with the moving force application means 4 and the power supply means (5).

&Lt; Example 2 >

In another embodiment of the present invention, the electric motor 42 is used as the force applying means 4, unlike the first embodiment using the solenoid.

4, the moving force application means 4 of the second embodiment includes a first power switching portion 43 for switching the rotational power of the electric motor 42 and the electric motor 42 to a linear power . The first power switching unit 43 is provided at one end of the rotary shaft of the electric motor 42 and functions as a main driving unit for the second power switching unit 213 to be described later.

5, the first power switching portion 43 has a rectangular shape when viewed from the top, and two inclined portions 431 and 432 having heights in the direction of the rotation axis of the electric motor are formed on both short sides of the lower surface of the first power switching portion 43, 432 are symmetrically formed in the rotating direction. The difference in height in the inclined portions 431 and 432 is formed to correspond to the distance between the angle fixing position and the fixed release position of the angle fixing means 21. [

The angle fixing means 21 includes a second power switching portion 215 for contacting the rotational power of the electric motor 42 with linear power in contact with the lower portion of the first power switching portion 43, Driven section). 4 (c), a hollow portion 214 is formed at the center of the angle fixing means 21, and the lower tuck portion of the hollow portion 214 functions as the second power switching portion 215 .

In the present embodiment, the first power switching portion 43 provided at one end of the rotary shaft of the electric motor 42 has the inclined portion on the lower surface thereof, as shown in Fig. 4 (a) In the hollow portion 214 of the angle fixing means 21 so as to come into contact with the inner surface of the hollow portion 214. [ So that the first power switching portion 43 can be inserted into the hollow portion 214 from the lower portion of the angle fixing means 21 (i.e., for convenience of assembly), as shown in Fig. 4 (b) It is preferable that the distance between the lower jaw portions of the hollow portion 214 is slightly larger than the length of the short side of the first power switching portion 43. [

Hereinafter, the operation of the moving force applying means of the second embodiment will be described in detail.

The second power switching portion 43 is provided with two inclined portions 431 and 432 on the lower surface of the first power switching portion 43. Therefore, The switching unit 215 receives a force in the direction of the rotation axis (for example, downward) as the first power switching unit 43 rotates together with the rotation shaft of the electric motor 42, whereby the angle fixing unit 21 It is separated or released from the angle regulating plate 22 and is moved to the fixed release position.

That is, the second power switching unit 215 is connected to the sloped portions 431 and 432 of the lower surface of the first power switching unit 43 at the thickest portion in the direction of the rotational axis (the portion having the highest height in the sloped portion when viewed from the bottom) The second power switching unit 215 is displaced downward to the maximum, so that the angle fixing unit 21 is separated from the angle regulating plate 22.

When the first power switching unit 43 rotates in this direction from the phase shown in Fig. 5 and the contact with the second power switching unit 215 is released (i.e., the second power switching unit, The angle fixing means 21 is moved to the angle fixing position by the resilient restoring force of the elastic means 25 and is engaged with the angle regulating plate 22, The angle is fixed.

The first power switching section 43 is rotated further from this state so that the second power switching section 215 is switched from the inclined sections 431 and 432 of the first power switching section 43 to the thinnest part The second power switching unit 215 is again pressed downward in the direction of the rotation axis and moves downward against the elastic force of the elastic means 25 . When the second power switching unit 215 reaches the thickest portion of the inclined portion of the first power switching unit 43, the angle fixing unit 21 reaches the fixed release position, Separated.

As described above, according to the second embodiment, by the upward / downward movement of the second power switching unit 215 according to the rotation of the electric motor 42, the angle fixing unit 21 can be reciprocated between the fixed releasing position and the angle fixing position And the saddle angle adjusting means 2 can be electrically operated by using the electric motor 42 and the power switching mechanisms 43 and 215.

In the case of Embodiment 2 using an electric motor, it is possible to apply a stronger moving force (releasing force) to the angle fixing means 21 as compared with Embodiment 1 using a solenoid. Thus, even when the user's weight is applied to the saddle, the angular position of the angle fixing plate 21 can be prevented from exceeding the frictional force between the engaging portion 211 of the angle fixing means 21 and the engaging groove 221 of the angle regulating plate 22, Can be separated from the angle regulating plate 22. Further, as compared with the first embodiment using the solenoid, since the elastic modulus of the fixing force applying means 25 can be increased, it is possible to stably maintain the fixed coupling between the coupling portion 211 and the coupling groove 221 in the angle fixed state .

The second power switching unit 215 formed on the hollow portion 214 of the angle fixing means 21 and the first power switching unit 43 having the inclined portion on the lower surface of the electric motor 42, However, the present invention is not limited to this, and it is also possible to adopt a different structure that can convert the rotational force of the electric motor 42 into linear power within a limited space of a bicycle saddle support.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes and modifications may be made without departing from the scope of the present invention .
