Technical Field

The present invention provides a stepless speed change power generation device, and particularly to a stepless speed change power generation device which has a small structural size and can automatically change speed according to output power and load.

Background

The stepless speed change power source is widely used in various occasions, and belongs to a moving carrier, and the speed of the moving carrier is changed through the stepless speed change mode, so that the purpose of speed change is achieved.

The current stepless speed change power source generally has a problem that a power source is combined with a stepless speed change mechanism to form a stepless speed change power source through the combination of the power source and the stepless speed change mechanism, in addition, the power source and the stepless speed change mechanism are usually made by different manufacturers, and because the size and structure of the stepless speed change mechanism and the power source made by each manufacturer are different, the volume after combination is too large, therefore, the mobile carrier carrying the stepless speed-changing power source cannot be miniaturized and is too heavy, and the cost is high due to the separated type manner, in addition, the power source will be lost when the stepless speed change mechanism and the power source are operated, so it can be easily seen that the design of separating the stepless speed change mechanism and the power source will cause many problems and inconveniences.

Furthermore, a Continuously Variable Transmission (CVT) is an automatic Transmission capable of Continuously adjusting a rotational speed and a torque conversion ratio, but as in taiwan patent No. M477730, "a structural improvement of a Continuously Variable Transmission motor", which integrates a Continuously Variable Transmission mechanism and a power source in a small housing, the operation of Continuously Variable Transmission is performed by relying on an adjustment member.

How to solve the above-mentioned problems and deficiencies is a direction in which the inventors of the present invention and related manufacturers engaged in the industry need to research and improve.

Disclosure of Invention

In view of the above-mentioned shortcomings, the inventor of the present invention has searched relevant data, evaluated and considered in many ways, and made a trial and modification with years of experience accumulated in the industry, and has designed an invention and patented a stepless speed change power generation device with a small structure and capable of automatically changing speed according to the output power and the load.

When the invention is used, the driving motor is used as a power source, the output shaft does not rotate together with the variable speed turntable through the arrangement of the ball disc, and the compression piece drives the counterweight balance piece to swing because the output shaft can move in the sliding groove of the sliding seat, further controls the counterweight balancing member to swing outwards according to the inertia or centrifugal force given to the counterweight balancing member by the rotating speed of the driving motor, and controls the counterweight balancing member to swing inwards by cooperating with the elastic component to drive the compression member, so as to change the offset of the speed-changing turntable, and simultaneously drive the speed-changing turntable to rotate through the sliding action of the output shaft, so that the slide block bearing rotating on the first bearing seat body deviates in the speed change chute to automatically change the moment of the speed change rotary disc, the slide block bearing can drive the second bearing seat body on the other side to drive the outer shell to rotate, and the power of the driving motor is output by the outer shell. When the output power of the driving motor is larger, the swing amplitude of the counterweight balance piece and the moment of the variable speed turntable are increased, otherwise, when the output load is larger, the swing amplitude and the moment are automatically reduced, so that the purpose of automatic stepless speed change is achieved.

By adopting the technical scheme, the problems of overlarge volume, high cost and incomplete automatic speed change existing in the combination of a power source and a stepless speed change mechanism of the conventional stepless speed changer can be solved, and the practical progress of the advantages is achieved.

A speed-changing turntable 6 rotatably disposed on the outer edge of the ball disc 3 and linked by the sliding action of the output shaft 11, and a plurality of speed-changing chutes 61 are formed on the speed-changing turntable 6;

a first bearing seat 71 disposed on one side of the variable speed turntable 6;

a plurality of slide bearings 62 movably disposed on the first bearing seat 71 and slidably disposed in the speed-changing sliding chute 61, wherein the moment of the speed-changing rotary disk 6 is automatically adjusted according to the distance between the slide bearings 62 and the output shaft 11, and the slide bearings 62 include a slide portion 621 disposed in the circular track 73, at least one rolling portion 622 disposed on the slide portion 621, and a bearing portion 623 pivotally disposed on the slide portion 621;

a rolling sliding groove 6211 formed on the slider portion 621 for the rolling portion 622 to roll;

a stop portion 6212 formed on the slider portion 621 and located at one side of the sliding slot 6211 for abutting against and fixing the rolling portion 622;

a second bearing seat 72 disposed on a side of the variable speed rotary table 6 away from the first bearing seat 71 and driven by the slider bearing 62 to rotate, wherein the first bearing seat 71 and the second bearing seat 72 respectively have an annular rail 73 for the slider bearing 62 to slide; and

An outer housing 8 disposed outside the second bearing housing 72 for outputting the power of the driving motor 1, and a linkage assembly 81 is disposed on the outer housing 8 for linking a generator 9.

The structure of the present invention can be understood from the above description, and according to the corresponding cooperation of the structure, the advantages of small structure volume, automatic speed change according to the output power and the load can be achieved, and the detailed description will be described below.

Referring to fig. 1 to 19, when the above-mentioned components are used, it can be clearly seen from the drawings that all the stepless speed change structures are disposed in an outer casing 8 and disposed on both sides of the speed change rotary disk 6 with the output shaft 11 as the center, so that the overall volume is small, and the output shaft 11 can be directly linked to a driving motor 1 for operation, and finally the outer casing 8 is driven to rotate by the stepless speed change structure, so as to achieve the effect of speed change output.

In practical use, referring to fig. 6 and 7 (only showing the output shaft 11, the sliding seat 2, the sliding groove 21, the roller disc 3, and the speed-changing turntable 6 for convenience of explanation), the output shaft 11 is driven by the driving motor 1 to rotate, the output shaft 11 is provided with a sliding seat 2, so that the output shaft 11 can make relative displacement with the sliding seat 2 by using the sliding groove 21 in the sliding seat 2, wherein the sliding groove 21 is a long slot hole, when the output shaft 11 of the driving motor 1 is limited to rotate only, the sliding seat 2 will make linear relative displacement with the output shaft 11 due to inertia or centrifugal force (as shown in fig. 6 and 7, the output shaft 11 abuts against two end surfaces of the sliding groove 21), the sliding seat 2 is fixed by using the positioning posts 22a and 22b to be respectively combined with the positioning holes 41a and 41b of the compression members 4a and 4b, so that the compression members 4a and 4b and the sliding seat 2 can be displaced simultaneously (as shown in fig. 8 and 9, the compression parts 4a and 4b are additionally shown compared with fig. 6 and 7), when the compression parts 4a and 4b abut against the output shaft 11, the positioning posts 22a and 22b swing around the axes, and the elastic component 43 is compressed, and the indirectly opened and closed state is shown in fig. 8 and 9.

In addition, referring to fig. 10 and 11 (in addition to fig. 8 and 9, the counterweight balance pieces 5a and 5b are shown), since the counterweight balance pieces 5a and 5b are sleeved on the output shaft 11 and are correspondingly connected with the pivot portions 42a and 42b of the compression pieces 4a and 4b through the connection portions 51a and 51b, and the pressing portions 441 of the connection seat 44 push the counterweight balance pieces 5a and 5b to move away from the sides of the connection portions 51a and 51b, the compression pieces 4a and 4b can swing and the counterweight balance pieces 5a and 5b can also swing. The connecting portions 51a, 51b may be in a clip shape or a collar shape, the pivot portions 42a, 42b are cylindrical, the left connecting portion 51b is fixed to the right pivot portion 42b, and the right connecting portion 51a is fixed to the left pivot portion 42a, so that when the pivot portions 42a, 42b are driven by the compression members 4a, 4b to displace, the connecting portions 51a, 51b drive the counterweight balance members 5a, 5b, and the counterweight balance members 5a, 5b rotate and swing around the output shaft 11.

Each time the driving motor 1 outputs a stronger force (faster speed), the swinging amplitude of the counterweight balance members 5a and 5b is larger due to inertia or centrifugal force, and the gravity center of the counterweight balance members 5a and 5b is shifted while swinging, so that the larger the swinging amplitude is, the gravity center is shifted outward, and the effect equivalent to shifting a high-speed gear is achieved. Similarly, when the output force of the driving motor 1 is weakened or the external load is increased (such as climbing), the effects of inertia and centrifugal force are weakened accordingly, the pushing elastic force of the elastic component 43 pushes the side surfaces of the counterweight balance members 5a and 5b by the abutting portion 441, so as to reduce the swing amplitude of the counterweight balance members 5a and 5b, thereby causing the center of gravity to retract, and further achieving the effect equivalent to the low gear of speed change.

Next, as shown in fig. 12 to 14 (only the force shaft 11, the sliding seat 2, the ball disc 3, the speed-changing rotary disc 6, the speed-changing sliding groove 61, the slider bearing 62, the first bearing seat 71, and the circular track 73 are shown for convenience of description), since the speed-changing rotary disc 6 is fastened to the outer edge of the ball disc 3, and the rotations of the inner side and the outer side of the ball disc 3 are independent, the speed-changing rotary disc 6 is not directly rotated by the rotation of the force output shaft 11, but the ball disc 3 is further mounted on the sliding seat 2, so that the relative linear displacement of the sliding seat 2 and the force output shaft 11 will also cause the displacement of the ball disc 3, and when the force output shaft 11 is continuously rotated, the speed-changing rotary disc 6 can also be rotated by inertia or centrifugal force. Because the output shaft 11 rotates on the spot, the first bearing seat 71 is fixed, and the rotation of the speed-changing rotary disk 6 is limited by the slide bearing 62, and the slide bearing 62 can only move along the ring-shaped slide rail 73, the speed-changing rotary disk 6 can rotate synchronously with the slide bearing 62, and also generates relative displacement through the speed-changing chute 61 and the slide bearing 62, and rotates with the output shaft 11 as the axis in a wave shape.

At this time, as shown in fig. 15 (comparing with fig. 12 and 13, the compression member 4, the balance weight 5, the sliding block bearings 62 on both sides of the speed-changing rotary table 6, and the second bearing seat 72 are added, and the first bearing seat is hidden), when the output shaft 11 rotates, the speed-changing rotary table 6 is driven to rotate, but the sliding block bearings 62 on both sides of the speed-changing rotary table 6 are displaced in the ring-shaped sliding rail 73 or generate friction with the ring-shaped sliding rail 73 due to the effect of the rolling part 622. Specifically, since the sliding block 621 has the rolling sliding slot 6211 and the stopping portion 6212, when the sliding block 621 is driven by the speed-changing turntable 6, the rolling portion 622 will have different expressions on two sides of the speed-changing turntable 6, wherein when the sliding block bearing 62 in the first bearing housing (hidden and not shown) is displaced, the rolling portion 622 can roll in the rolling sliding slot 6211, so that the sliding block 621 and the ring-shaped sliding rail 73 can be displaced relatively; on the other hand, the slider bearing 62 of the second bearing housing 72 is similarly subjected to the thrust of the shift dial 6, but the rolling portion 622 is locked to the stopper portion 6212 side and is not rotated, and the rolling portion 622 and the ring-shaped slide rail 73 of the second bearing housing 72 generate a frictional force. Therefore, the rotation of the output shaft 11 will drive the rotation of the speed-changing rotary disk 6, and the rotation of the speed-changing rotary disk 6 will drive the rotation of the second bearing seat 72 by the friction force.

As shown in fig. 15 to 17, when the shift dial 6 rotates, the bearing portion 623 is displaced relative to the first bearing housing 71 and the second bearing housing 72 regardless of whether the slider portion 621 moves along the circular track 73 by the rolling portion 622, so that the bearing portion 623 of the slider bearing 62 changes in distance from the output shaft 11 in the shift chute 61, and the effect equivalent to shifting to a high speed is naturally achieved when the bearing portion 623 is farther from the output shaft 11, i.e., the turning moment of the shift dial 6 is larger, whereas the effect equivalent to shifting to a low speed is naturally achieved when the bearing portion 623 is closer to the output shaft 11, i.e., the turning moment of the shift dial 6 is smaller. The purpose of stepless automatic speed change is achieved by the balance weight 5.

Finally, as shown in fig. 18 and 19, since the second bearing seat 72 is directly fixed on the outer housing 8 through a fixing member 82 (e.g. a screw), and is not in contact with the output shaft 11, but only in contact with the sliding block bearing 62 in the stepless speed change structure, the sliding block bearing 62 rotates on the annular sliding groove 73 of the first bearing seat 71, and simultaneously acts on the second bearing seat 72, so that the second bearing seat 72 drives the outer housing 8 to rotate, and the linkage assembly 81 is only arranged on the outer housing 8, so that the linkage assembly 81 can output the power of the driving motor 1 after speed change, when the present invention is connected to the vehicle generator 9, the power of the driving motor can be output at variable speed through the transmission of the linkage assembly 81, and through the speed change effect of the present invention, the energy conversion efficiency is improved, and the effects of low power consumption and high torque output can be achieved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, so that the present invention is not limited by the accompanying drawings.
