It is of an electric toothbrush drive system consisting of a coil spring for providing a resilient force is always engaged with the post ridorok simkaem.
- the above technique basically relates to a driving device of an electric toothbrush using a link member motion conversion linked to an eccentric cam, and a technology using the same by converting an eccentric motion into a primary motion is described.
- the rotation radius of the eccentric cam must be increased in order to increase the movement width of the final movement member.
- the device which converts the eccentric cam motion into a linear motion with less load on the eccentric cam, especially in the device that converts the eccentric rotational motion into a linear motion and finally converts it into an arc motion. It is necessary to develop a technique for a method and a device that can immediately use the amount of exercise.
- the present invention has been made to solve the above problems of the prior art,
- the eccentric cam it is intended to use the eccentric cam to change the direction of motion of the eccentric cam more efficiently and to change the rotational motion of the eccentric cam into the circular motion as efficiently as possible.
- the main point is to make the circular motion of the amplified distance finally achieved with a small amount of eccentricity. It was completed as a technical problem with the focus on providing a device and method that can be applied to the device for generating arc motion using an eccentric cam using a large RPM or a large amount of power using this.
- connecting the connecting rod (C) to the motion conversion member (D) is formed by the driving groove (h) in the motion conversion member (D), one side of which is fixed to the hinge axis (h) by engaging with the drive groove (h)
- the motion conversion member (D) can perform circular arc motion according to the change of the position of the driving groove (h) to be interlocked, and the motion conversion member is divided into upper and lower parts.
- each of the driving grooves (h, h ') are all connected to one connecting rod (C) by a pin or the like, the driving grooves (h, h') are connected to the connecting rod (C)
- the upper and lower motion converting members (D) are configured to be circular motions in opposite directions according to the linear motion of the connecting rods.
- the shape of the drive groove (h) and the position of the axis in the above it was also possible to vary the movement direction and the movement distance.
- the eccentric cam in the circular motion after the rotation of the eccentric cam rotation, the eccentric cam is derived by deriving the circular motion effect whose distance is finally amplified by the member moving in opposite directions.
- Eccentric cams or devices that take a lot of load can be used, but they can be efficiently applied to arcing devices that require large moving distances.In the case of large-capacity drives, inefficiencies such as loads and failures concentrated on eccentric cams are solved. It can be applied to a variety of devices by providing a stable driving relationship, such as the effect that can be widely applied and used in the circular motion drive device of the entire industry.
- FIG. 3 is a plan view showing a preferred embodiment of the present invention
- FIG. 6 is a plan view showing a preferred embodiment of the present invention.
- the methods are applied to the motion conversion of a variety of mechanical devices, as described briefly in the prior art, and accordingly the primary conversion in the device using the eccentric cam to convert the rotational motion to other direction of motion That is, it is a general fact that the eccentric rotational movement is used by converting the movement in various directions.
- an eccentric cam In the case of a power unit that makes circular motions by changing the direction of movement, the range of motion of the circular motion medium is determined by the size of the eccentric cam. Therefore, if the diameter of the eccentric cam is increased to increase the circular arc motion, centrifugal force is generated. High speed rotation was not possible, and therefore, the driving of a large eccentric cam was impossible in a device requiring high rpm.
- the present invention relates to a device and method that can be used to amplify the range of circular motion by using the rotational force of the same eccentric cam eccentric motion (primary), linear motion (secondary), circular motion (3)
- the present invention relates to an apparatus and a method for achieving a method of amplifying a range of motion of a circular arc motion (3rd order) and applying it to a device in the process of performing a circular motion by changing the order of difference).
- the drive unit (A) can be configured in various ways depending on the device and the situation applied. In some cases, it may be configured by connecting the eccentric cam (B) directly to the rotational power source.
- the connecting rod (C) is configured to be connected to one side of the eccentric cam (B), but the connecting rod (C) is configured to be linked with the rotation of the eccentric cam (B).
- the connecting rod (C) is a linear reciprocating motion in accordance with the rotation of the connected eccentric cam (B) may be configured as a guide guide (not shown) for guiding the movement of the connecting rod (C) as necessary. Straight reciprocating motion)
- connection rod (C) As shown in Figures 1 and 2 is connected to the connection rod (C) to one side is configured to connect the motion conversion member (D) to perform an arc motion, the motion conversion member (D) is based on one side rotatable It is fixed to the hinge shaft (t) on one side of the main body (not shown) is provided with a driving groove (h) is configured to connect and connect so that the connection rod (C) and the driving groove (h) are interlocked and driven. .
- connection rod (C) extends to the upper or lower one side of the driving groove (h) by using the locking means may be configured by connecting the connecting rod (C) in the driving groove (h) to interlock with each other. It is possible to apply using a number of known connection means.
- hinge shaft (t) fixed motion conversion member (D) is driven in accordance with the linear reciprocating operation of the connecting rod (C) is moved in conjunction with the drive groove (h) is to move the motion conversion member (D) will be.
- the configuration direction of the driving groove h is important, but the driving groove h is formed in an oblique direction crossing the movement direction of the connecting rod C, which is a linear reciprocating means.
- the motion conversion member (D) is to perform an arc motion.
- each of the driving grooves h and h ' is formed in an oblique direction crossing the movement direction of the connection rod C, as mentioned above, and is connected to the connection rod C to include all of them. It is configured to intersect or meet at an angle with respect to the binding point (p) between the connecting rod (C) and the driving grooves (h, h ').
- each of the motion conversion devices (D, D ') are circular motions in opposite directions as they move in the respective driving grooves (h, h').
- connection can be driven by connecting two motion conversion devices (D, D ') with one connection rod (C), but if necessary, the driving grooves of the motion conversion devices (D, D') ( h, h ') can be configured so as not to overlap, even if the connection rods (C, C') corresponding to each of the configuration separately can be completed the same movement. That is, according to the necessity of the exercise device, a motion conversion device having a plurality of connection rods and respective driving grooves corresponding thereto may be separately configured to amplify the range of motion.
- the width of the amplified motion may be adjusted in various ways.
- the motion conversion member D may have one side fixed to the hinge axis t and the hinge axis t.
- the width of the circular arc motion may vary depending on the distance of the binding point p of the connecting rod C on the driving grooves h and h '. That is, if the distance between the hinge axis (t) and the binding point (p) is far from the same condition as shown in Figure 5, the width of the circular arc motion is narrow and the load required to rotate the eccentric cam (B) is also short, if the width of the circular arc motion It can be seen that the width becomes wider and thus the load applied to the rotation of the eccentric cam B becomes large. As shown in FIG. 6, the moving range may be changed according to the crossing angles of the driving grooves h and h '.
