Detailed Description

The present invention will be described in detail with reference to the accompanying drawings. The detailed description and drawings herein are merely illustrative, and are not intended to be limiting.

Fig. 1-3 illustrate a pendulum type lever power generation device according to one embodiment of the present invention. The pendulum type lever power generation device mainly comprises a swing device 1, a power input device and a power output device 6.

The swing device 1 comprises a base 2, an outer swing component 3, an inner swing component 4 and a friction device 5. Wherein the outer and inner pendulum assemblies 3, 4 are preferably frame structures to provide sufficient strength while reducing weight and material costs.

In a preferred embodiment, the skirt assembly 3 comprises at least two triangular brackets 31. Two adjacent triangular brackets 31 are connected to each other by a plurality of links 32 extending in the lateral direction. In addition, the number of the triangular brackets 31 can be conveniently increased as required to expand the capacity of the power generation device. In another embodiment, a plurality of triangular brackets 31 and their connecting links 32 may be integrally formed to provide greater strength.

Preferably each triangular bracket 31 is pivotally connected to the base 2 at a pivot point at its base. The pivot points at the bottom of each triangular bracket 31 are located on the same line (first pivot a 1). The swing-out assembly 3 is thus able to swing between a rest position and two deflected positions with respect to this first pivot a1 at the bottom edge. Each pivot point is preferably located at a position intermediate the respective base edges, in which case the two deflection positions are mirror-symmetrical with respect to the equilibrium position. However, depending on the actual situation, it is also possible to arrange the pivot point offset, in which case the two offset positions are not symmetrical with respect to the equilibrium position.

A second pivot a2 is provided between the apexes of two adjacent triangular brackets 31. For example, bearings may be provided at the apexes of each triangular bracket 31 with the pin 33 extending between adjacent bearings. In the case of more than two triangular brackets 31, a respective pin 33 may be provided between each two adjacent triangular brackets 31, or a single pin 33 may extend across multiple bearings. The pin 33 can thus be rotated relative to the triangular brackets. Of course, any other suitable structural arrangement is possible.

Third and fourth pivots A3, a4 are provided at both sides of the triangular bracket 31, respectively. The third and fourth pivots A3, a4 may be provided in a similar manner as the second pivot a 2. For this purpose, friction means 5 are provided between adjacent triangular brackets 31. The friction means 5 comprise lateral shafts 51 mounted between the corresponding sides of two adjacent triangular brackets 31. These side shafts 51 can be turned relative to the triangular bracket 31 in which they are mounted. The friction device 5 further comprises a friction wheel 52 provided on the side shaft 51, which friction wheel 52 is non-rotatably connected with the side shaft 51. In another embodiment, the friction wheel and the side shaft 51 may be integrally formed.

In another embodiment, the friction means 5 (and therefore the third and fourth pivot axes A3, a 4) are not provided on the triangular support 31, but are arranged positionally fixed but rotatably with respect to the base 2. This position is preferably located inside each triangular bracket 31 so as not to interfere with the swinging movement of each triangular bracket 31.

Of course, the above-mentioned support 31 of the swing-out assembly 3 does not have to be triangular, but any other suitable configuration is possible. Accordingly, the positions of the pivot shafts a1, a2, A3, a4 can be set appropriately.

The inner swing assembly 4 preferably has the form of a triangular bracket 41. Between two adjacent supports 31 of the outer pendulum assembly 3, a support 41 of the inner pendulum assembly 4 is arranged, but other suitable numbers are also possible. The triangular support 41 of the inner swing assembly 4 is fixedly attached at its apex to the pin 33 (i.e., second pivot axis a 2) of the outer swing assembly 3. This allows the triangular support 41 of the inner swing unit 4 to swing with respect to the support 31 of the outer swing unit 3. In another embodiment, the pin 33 is fixedly connected between the adjacent brackets 31 of the adjacent outer swing assemblies 3, and the bracket 41 of the inner swing assembly 4 can rotate relative to the pin 33.

The triangular support 41 of the inner swing assembly 4 is preferably a frame structure provided with at least one counterweight 43 on the inside. These weights 43 are detachably mounted to the triangular brackets 41 of the inner swing assembly 4. These weights 43 are preferably provided in a modular fashion so that a desired number and weight of weights 43 can be provided as needed. In other embodiments, the weights 43 may also be formed as a non-removable portion of the hypocycloid assembly 4.

The bottom side of the triangular support 41 of the inner swing assembly 4 includes a slider structure 42. When the friction device 5 is mounted on the swing-out assembly 3, the slider structure 42 has a circular arc configuration with a center located on the second pivot a2 connecting the triangular support 41 of the swing-in assembly 4 and the support 31 of the swing-out assembly 3. Thus, when the inner swing assembly 4 swings relative to the outer swing assembly 3, the slider structure 42 can slide relative to the friction wheel 51 mounted on the outer swing assembly 3, thereby driving the friction wheel 51 to rotate. When the friction device 5 is mounted on the base 2, the slider structure 42 does not have to have a circular arc configuration, or its center may not coincide with the second pivot a2 connecting the triangular support 41 of the internal swing assembly 4 and the support 31 of the external swing assembly 3. The slider structure 42 may be a particular cam configuration that is readily obtained by a method of trajectory envelope.

Of course, the above-described support 41 of the hypocycloid assembly 4 need not be triangular, and any other suitable configuration is possible.

Power input means are also provided to the oscillating device 1. The power input means may be provided in a number of ways and is therefore not shown in the figures. The power input device is used for driving the swinging assembly 3 to swing relative to the first pivot A1. In one embodiment, an input interface 7 may be provided at the apex of the triangular support 31 of the swing-out assembly 3 to which the power input device is connected. In one embodiment, the power input device provides a rotational input through which the swinging of the swing-out assembly 3 about the first pivot axis a1 is achieved. In another embodiment, the power input device provides a translational input by which the push-pull sway assembly 3 swings relative to the first pivot axis a 1.

The power source of the power input device may be varied. For example, the power input may be from a motor input, redundant power from an engine of a motor vehicle, watercraft, aircraft, such as a bicycle, exercise equipment, or the like, common in everyday life, wind, water, tide, or any other device capable of generating power. The point of how to convert the power into power capable of driving the swinging of the pendulum assembly of the present invention is not the focus of the present invention.

A power output device 6 is also provided to the friction device 5, and the power output device 6 functions to output the rotational energy of the friction wheel 52 to the power generation device 8 for conversion. In one embodiment the side shaft 51 on which the friction wheel 52 is mounted extends outside the adjacent bracket 31 of the epicycloidal assembly 3. Here, a flywheel 61 of the power take-off 6 is provided. The flywheel 61 is further connected to the power generation device 8, thereby converting the rotational energy of the friction wheel 51 into electric energy. Of course, other suitable power take-offs 6 are possible.

The method of operation of the apparatus of the present invention is described below with reference to fig. 4.

First, the swing-out assembly 3 of the apparatus of the present invention starts to swing under the power input means S1, and the pin 33 (second pivot a 2) connected to the top of the bracket 31 also follows the swing. Accordingly, the inner swing assembly 4 follows the movement. At the same time, the inner swing member 4 swings about the second pivot a2 with respect to the outer swing member 4. The above-described swing of the inner swing assembly 4 following the second pivot a2 and the swing of the inner swing assembly 4 with respect to the second pivot a2 are superimposed on each other, so that the swing of the slider 42 at the bottom side of the inner swing assembly 4 is amplified by the principle of leverage. During the swinging process of the internal swing component 4, the sliding block 42 at the bottom edge of each bracket 41 of the internal swing component 4 and the friction wheel 52 mounted at the side edge of each bracket 31 or the base 2 of the external swing component 3 move relatively, so that the friction wheel 52 is driven to rotate. Due to the aforementioned lever amplification, a small external input is required to achieve high speed pivoting of the friction wheel 52. The high-speed pivoting of the friction wheel 52 is output by the side shaft 51 to the flywheel 61, and the flywheel 61 in turn outputs rotational energy to the power generation device 8 to be converted into electric energy.

According to the aforesaid configuration of the apparatus of the present invention, it can be found that swinging the swing-out assembly 3 about the first pivot a1 is easily accomplished, and a small force is required to swing the swing-out assembly 3 between the deflected positions on both sides of the equilibrium position. Therefore, the power level requirements of the power input are very low. This enables the apparatus of the present invention to easily and adequately pick up redundant power from the environment and convert it to electrical energy.

Under the aforementioned lever amplification, the inner swing assembly 4 can achieve a large swing amplitude, so that the friction wheel 52 can rotate at high speed. The device of the invention thus enables the conversion of power input even at lower power levels with high efficiency.

Of course, the present invention can also be very conveniently adapted to power inputs of higher power levels, for example, by increasing the size of the outer and inner pendulum assemblies 3, 4, increasing the weight of the counterweight 43 of the inner pendulum assembly 4, and increasing the number of outer and inner pendulum assemblies 3, 4. For example, when the support frame 31 of the outer swing assembly 3 has a high height, the second pivot a2 can achieve a large swing amplitude, thereby enabling the inner swing assembly 4 to achieve a large swing amplitude. In another embodiment, when the hypocycloid assembly 4 has a larger mass of the counterweight 43, the slider block 52 of the hypocycloid assembly 4 can apply a larger frictional force to the friction wheel 52, thereby accelerating the rotation of the friction wheel 52. In yet another embodiment, a plurality of power generation devices may be connected in parallel, that is, more than two brackets 31 of the outer pendulum assembly 3 are provided, and at least one inner pendulum assembly 3 is provided between each two adjacent brackets 31, where the energy that the device can output is multiplied.

To maximize the swing of the inner swing assembly 4, it is preferable to start swinging the outer swing assembly 3 in the opposite direction when the inner swing assembly 4 moves to the maximum biased position.

To conserve energy, the power input device may provide intermittent power input. In connection with the previous embodiments, the power input means may only briefly apply power to the swing-out assembly 3 when the swing-in assembly 4 is moved to the maximum biased position.

As a non-limiting example, the triangular supports 31 of the epicycloidal assembly 3 may have dimensions 2500mm x 1200mm, providing 1 bearing of 25mm at the apex of each support 31, the distance between two adjacent supports being 100mm, connected with a plurality of links having a diameter greater than 25 mm. The power input means may provide power input intermittently for 0.5-1.5 seconds.

The above description is only a partial embodiment of the present invention, and any equivalent changes or modifications of the structure, features and principles described in the scope of the present application, or any combination of the embodiments of the present invention, are included in the scope of the present invention.
