Through the above description, we can understand the structure of this technology, and according to the corresponding cooperation of this structure, it can achieve the advantages of small structure and automatic speed change according to the output power and load. The detailed explanation will be as follows Description.

Please also refer to the first to nineteenth figures, which are the three-dimensional view of the preferred embodiment of the present invention to the schematic diagram of the generator driving. When the above-mentioned components are assembled, it can be clearly seen from the figure that the present invention is All the continuously variable transmission structures are arranged in an outer shell 8, and are centered on the output shaft 11, and are arranged on both sides of the transmission turntable 6, so the overall volume is small, and the output shaft 11 can be directly connected to a drive The motor 1 operates, and finally drives the outer casing 8 to rotate through the continuously variable transmission structure to achieve the effect of variable speed output.

In actual use, please refer to Figure 6 and Figure 7 (only the force shaft 11, sliding seat 2, sliding groove 21, roller plate 3, and variable speed dial 6 are shown for ease of explanation), which is driven by the drive motor 1. The output shaft 11 is driven to rotate. The output shaft 11 is provided with a sliding seat 2 so that the output shaft 11 can utilize the sliding groove 21 in the sliding seat 2 to move relative to the sliding seat 2, wherein the sliding groove 21 is long. When the output shaft 11 of the drive motor 1 is restricted from rotating, the sliding seat 2 will have a linear relative displacement with the output shaft 11 due to inertia or centrifugal force (as shown in Figures 6 and 7). As shown, the output shaft 11 is pressed against the two end faces of the sliding groove 21), and the sliding seat 2 is fixed with the positioning holes 41a, 41b of the compression members 4a, 4b by using positioning posts 22a, 22b, so that the compression members 4a, 4b 4b and the sliding seat 2 are displaced at the same time (as shown in the eighth and ninth figures, compared with the sixth and seventh figures, the compression members 4a and 4b are added), and when the compression members 4a and 4b collide with the output shaft 11, Swing with the positioning posts 22a and 22b as the axis, and at the same time cause the compression of the elastic element 43, and present the state of indirect opening and closing as shown in the eighth and ninth figures.

In addition, please refer to the tenth and eleventh figures (compared to the eighth and ninth figures, the counterweight balance pieces 5a and 5b are added), because the counterweight balance pieces 5a and 5b are sleeved on the output shaft 11. And through the joint parts 51a, 51b and the compression parts 4a, 4b pivot parts 42a, 42b correspondingly, and the bearing part 441 of the connecting seat 44 pushes the counterweight balance members 5a, 5b away from the joint parts 51a, 51b side This action causes the compression members 4a and 4b to swing while also causing the counterweight and balance members 5a and 5b to swing. The connecting portions 51a, 51b can be in the shape of a clip or loop, and the pivot portions 42a, 42b are in a cylindrical shape, and the connecting portion 51b on the left is fixed to the pivot on the right. The shaft portion 42b and the right coupling portion 51a are fixed to the left pivot portion 42a. When the pivot portions 42a and 42b are displaced by the compression members 4a and 4b, they will drive the counterweight balance members 5a and 5b through the coupling portions 51a and 51b. , And the weight balance members 5a, 5b are rotated and oscillated with the output shaft 11 as the axis.

Whenever the output power of the drive motor 1 is stronger (the faster the speed), the greater the swing amplitude of the counterweight balance members 5a, 5b due to inertia or centrifugal force, and the greater the swing of the counterweight balance members 5a, 5b when they swing. The center of gravity is shifted, so the larger the swing, the shift of the center of gravity will be caused, which is equivalent to changing the high gear. In the same way, when the output force of the driving motor 1 is weakened or the external load increases (such as climbing), the effects of inertia and centrifugal force will also be weakened, and the pushing force of the elastic element 43 will be used to push the resisting portion 441 The side surfaces of the counterweight balance pieces 5a, 5b reduce the swing range of the counterweight balance pieces 5a, 5b, which causes the center of gravity to shrink, thereby achieving an effect equivalent to a low gear.

Next, please refer to Figures 12 to 14 (only the force shaft 11, sliding seat 2, ball disk 3, shift turntable 6, shift slide 61, slider bearing 62, first bearing seat are shown Body 71, ring-shaped track 73, for ease of description), because the shift turntable 6 is located on the outer edge of the ball disk 3, and the inner and outer sides of the ball disk 3 rotate independently, so the shift turntable 6 will not directly receive the output shaft 11 However, the ball disk 3 is also provided on the sliding seat 2, so the relative linear displacement of the sliding seat 2 and the output shaft 11 will also cause the displacement of the ball disk 3 at the same time. When the output shaft 11 continuously rotates, further The variable speed dial 6 can also be rotated by inertia or centrifugal force. In addition, the output shaft 11 rotates in place, the first bearing housing 71 is fixed, and the rotation of the shift turntable 6 is limited by the slider bearing 62, which can only move along the ring-shaped slide rail 73. In addition to rotating synchronously with the slider bearing 62, the shift turntable 6 will also generate a relative displacement through the shift chute 61 and the slider bearing 62, and rotate slightly with the output shaft 11 as the axis.

At this time, as shown in the fifteenth figure (compared to the twelfth and thirteenth figures, the compression piece 4, the counterweight balance piece 5, the slider bearing 62 on both sides of the shift turntable 6 and the second bearing housing body are added 72, and hide the first bearing housing). When the output shaft 11 rotates, it will drive the shift turntable 6 to rotate, but the slider bearings 62 on both sides of the shift turntable 6 are in the ring slide 73 due to the effect of the rolling part 622 Displacement or friction with the ring-shaped slide rail 73 is generated. Specifically, because the slider portion 621 has a rolling chute 6211 and a limiting portion 6212, when the slider portion 621 is driven by the shifting dial 6, the rolling portion 622 will have different performances on both sides of the shifting dial 6. Among them, When the slider bearing 62 in the first bearing housing body (hidden and not shown) is displaced, the rolling portion 622 is rolled in the rolling slide groove 6211, so that the slider portion 621 produces relative displacement with the ring-shaped sliding rail 73; on the contrary, the slider bearing 62 in the second bearing housing body 72 is also subjected to the thrust of the shift turntable 6, but because its rolling part 622 is locked on the side of the limiting part 6212 Without rotation, friction force is generated between the rolling portion 622 and the ring-shaped slide rail 73 of the second bearing housing 72. Therefore, the rotation of the output shaft 11 will drive the speed change dial 6 to rotate, and the rotation of the speed change dial 6 will drive the second bearing housing body 72 to rotate by friction.

Please refer to the fifteenth to seventeenth figures. When the shift turntable 6 rotates, no matter whether the slider part 621 is moved along the annular track 73 by the rolling part 622, the bearing part 623 can be combined with the first bearing seat The body 71 and the second bearing housing body 72 produce relative displacement, so that the bearing portion 623 of the slider bearing 62 produces a change in the distance from the output shaft 11 in the speed change chute 61. When the bearing portion 623 is farther from the output shaft 11, that is, As a result, the greater the rotational torque of the shift turntable 6 will naturally achieve the effect equivalent to shifting high gears. On the contrary, when the bearing portion 623 is closer to the output shaft 11, the smaller the rotational torque of the shift turntable 6 will be, and the result will naturally be equivalent to The effect of changing low gears. In this way, the purpose of stepless automatic transmission is achieved together with the counterweight balance member 5.

Finally, as shown in the eighteenth and nineteenth figures, the eighteenth figure is a perspective view of the outer shell from another angle, because the second bearing housing body 72 is directly fixed to the housing through a fixing member 82 (such as a screw) The outer casing 8 is not in contact with the output shaft 11, but only in contact with the slider bearing 62 in the continuously variable transmission structure. Therefore, the slider bearing 62 rotates on the ring-shaped sliding groove 73 of the first bearing housing 71 At the same time, it will have an effect on the second bearing housing body 72, causing the second bearing housing body 72 to drive the outer housing 8 to rotate. Therefore, as long as the linkage assembly 81 is provided on the outer housing 8, the geared drive motor 1 can be output by the linkage assembly 81. Therefore, when the present invention is connected to the vehicle generator 9, it can be transmitted through the linkage assembly 81 to output the power of the drive motor at a variable speed. Through the variable speed effect of the present invention, the energy conversion efficiency is improved, and low power consumption can be achieved. The effect of consumption and high torque output.

However, the above descriptions are only preferred embodiments of the present invention, and are not limited to the scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the description and drawings of the present invention should be the same. It is included in the scope of the patent of the present invention, and it is hereby stated.

In summary, the continuously variable variable speed power generation device of the present invention can indeed achieve its efficacy and purpose when used.
