Referring to fig. 1 to 27, the embodiment of the invention provides a pull-type rotary power platform for charging. Fig. 1 is an appearance schematic diagram of an embodiment of a pull-type rotary power platform provided by the invention. It should be noted that the pull-type rotary platform may be the one shown in fig. 1, or may be a pull-type rotary platform for charging in other forms or applications. The person skilled in the art can easily change the form without creative improvement to make a pull type rotary power platform with different forms. It should be noted that a pull-type rotary power platform, made or formed based on the concepts described herein, even if different in structure or configuration, should be considered within the scope of the present invention. Turning to fig. 1-4, fig. 2 is a perspective view of a pull-type rotary power platform according to an embodiment of the present invention after the housing is opened. Fig. 3 is a schematic view of an embodiment of a connection structure between a generator module and a tie rod module provided by the present invention. Fig. 4 is a schematic structural diagram of an embodiment of a power generation module provided by the present invention. The embodiment of the invention provides a pull-type rotary power platform for charging, which comprises a generator module 200, charging pins (710a,710b), a pull rod module 1000 and a platform 300a for supporting a device to be charged, and can be referred to as a supporting platform hereinafter. The device to be charged may include, but is not limited to, an electric toy car. The generator module 200 is connected to the charging pins (710a,710b) by wires. The drawbar module 1000 includes a pull/push rod 1020 and a shaft 1010 perpendicularly connected to one end of the pull/push rod 1020, the shaft 1010 being inserted from one side of the support platform and penetrating through opposite sides of the platform 300 a. And, the pull/push bar 1020 is on one side of the support platform 300a, and the shaft 1010 is rotatable within the support platform 300 a. Wherein the pull/push rod 1020 may be in the shape of a handle or a shape that is easy for a user to push and pull, and the user may be a child. One end of the charging pin (710a,710b) is fixed to the shaft 1010, and the other end is a hook portion. The charging pins (710a,710b) are used for buckling the device to be charged and charging the device to be charged. For example, the charging pins (710a,710b) snap onto the bottom of the electric toy vehicle and connect to the power supply components of the electric toy vehicle to charge the power supply components. When the pull/push rod 1020 is pushed forward or backward, the charging pins (710a,710b) rotate with the rotation of the shaft 1010, so that the hooks of the charging pins (710a,710b) catch or release the device to be charged to charge or stop charging the device to be charged. For example, the device to be charged is placed on the platform 300a, the charging pins (710a,710b) are located below the device to be charged, and the platform 300a may have a frame shape as long as it is reached to support the device to be charged. Alternatively, the platform 300a has an opening that may facilitate entry and exit of the hook portion of the charging pin (710a,710 b). When the pull/push rod 1020 is pushed forward or backward, the shaft 1010 rotates and drives the charging pins (710a,710b) to rotate upward or downward, and the hooks of the charging pins (710a,710b) can enter and exit from the openings of the platform 300a to catch or release the device to be charged.

In some embodiments, when the support platform 300a is placed on a ground or plane, there is an oblique angle between the surface of the support platform 300a and the ground or plane. The device to be charged can be moved forward when a charging pin (710a,710b) of a pull-type rotary power platform releases the device to be charged. For example, when the charging pin (710a,710b) of a pull-type rotary power platform releases the electric toy vehicle, the electric toy vehicle rolls forward along the inclined support platform 300a as the electric toy vehicle is charged to begin driving the wheels to rotate.

In some embodiments, the generator module 200 may include, but is not limited to, a manual power generation mode such as a hand power generation mode, and the like, and may also control the generator to generate power by using an external control mode.

In some embodiments, as shown in FIG. 2, a pull-type rotary power platform may further include a housing 300 integrally formed with the platform 300a, with the generator module 200 disposed inside the housing 300. The housing 300 is configured to mate with the generator module 200, to accommodate the generator module 200 and to facilitate generation of electricity by the generator module 200. For example, providing an interface to a hand cranking or hand pulling assembly and connection in the housing 300 may generate renewable power without the need for an external power source to provide power. For another example, an interface for connecting to an external motor is provided in the housing 300, and power can be supplied from the external motor. The housing 300 provided in this embodiment is intended to provide a stable environment for the generator module 200 to operate to generate more power.

In some embodiments, as shown in fig. 4, the generator module 200 includes the flywheel module 100, the connection belt 230, and the dc motor 210. The connecting belt 230 may be a closed loop belt, the connecting belt 230 is disposed on the first pulley 120 on the flywheel module 100 and the second pulley 220 on the shaft of the dc motor 210, and the first pulley 120 and the second pulley 220 are simultaneously looped in a loop surrounded by the connecting belt 230; when the flywheel module 100 is rotated by an external force, the first pulley 120 is rotated, the connection belt 230 on the first pulley 120 is moved, and since the connection belt 230 is also positioned on the second pulley 220, the second pulley 220 is also rotated along with the movement of the connection belt 230. Since the second pulley 220 is fixed to the shaft of the dc motor, the shaft of the dc motor 210 also rotates with the rotation of the second pulley 220, so that the dc motor 210 generates power. In the present embodiment, the dc motor 210 has a function of generating power, and when the shaft of the dc motor 210 rotates, the dc motor 210 starts generating power. When the shaft of the dc motor 210 stops rotating, the dc motor 210 stops generating power.

In the embodiment, the diameter of the first pulley 120 may be much larger than that of the second pulley 220, and when the first pulley 120 rotates one turn, the second pulley 220 may rotate multiple turns, so as to improve the power generation efficiency, especially in the case of pull-type manual power generation.

In some embodiments, as shown in fig. 5, fig. 5 is a schematic diagram of a disassembled structure of an embodiment of the flywheel module 100 provided by the present invention. The flywheel module 100 comprises at least one ring gear 130, said first pulley 120, at least one flywheel 110 and a shaft 160. The ring gear 130, the flywheel 110 and the first belt pulley 120 are sequentially fixed on the shaft 160 of the flywheel module 100, the ring gear 130 is sleeved into the shaft hole of the flywheel 110 from one side surface of the flywheel 110, and the other side surface of the flywheel 110 is attached to the first belt pulley 120. Of course, in some embodiments, two sides of the first pulley 120 respectively engage with one flywheel 110 and the shaft hole of the flywheel 110 is sleeved with the ring gear 130. Specifically, the following are:

the flywheel module 100 includes two ring gears 130, a first pulley 120, two flywheels 110, and a shaft 160. The first pulley 120 is sandwiched between the two flywheels 110 and fixed to the shaft 160 of the flywheel module 100 and the two flywheels 110 have a radius larger than that of the first pulley 120. In this manner, the connection provided on the first pulley 120 can be prevented from being detached from the first pulley 120 while moving. Two ring gears 130 are respectively inserted from both sides of the shaft 160 and are fitted into shaft holes of the two flywheels 110. The flywheel 110 may be rotated when the ring gear 130 rotates. Since the first pulley 120 is caught between the flywheels 110, the first pulley 120 rotates along with the flywheels 110.

In some embodiments, the flywheel module 100 further includes ball bearings 140 disposed on both edges of the shaft 160 of the flywheel module 100, or other additional components similar to the ball bearings 140. The ball bearings 140 can minimize friction when the flywheel 110 module 100 rotates, reduce resistance to rotation of the flywheel 110 module 100 to a higher rotational speed and a longer rotational time, thereby generating more power.

As shown in fig. 6, fig. 6 is a schematic view illustrating an installation of the dc motor 210 and the second pulley 220 provided in the present invention. The shaft 212 of the dc motor 210 is inserted into the shaft hole of the second pulley 220. The dc motor 210 has current outputs including a "+" current output 210a and a "-" current output 210 b. As shown in FIG. 20, "+" current output 210a is connected to charging pin 710a via conductor 212a, and "-" current output 210b is connected to charging pin 710b via conductor 212 b. The charge pin 710a carries a positive "+" current and the charge pin 710b carries a negative "-" current.

In some embodiments, as shown in fig. 7, the housing 300 is in the shape of a whistle, and the housing 300 includes a platform 300a located at the whistle of the housing 300 and a cylindrical cavity 300b laterally engaged with the platform 300 a. The platform 300a and the cylindrical cavity 300b may be integrally formed, and the connection therebetween may also be detachable. As shown in fig. 7 and 8, fig. 7 and 8 are schematic structural views of an opened case 300 according to an embodiment of the present invention. The housing 300 can be disassembled into two parts from the central axis of the housing 300, so that the components in the housing 300 can be conveniently disassembled. Wherein both bottom planes of the cylindrical cavity 300b are perpendicular to the plane of the platform 330 a. The center points of the inner walls of the two opposing bottom planes (i.e., the inner planes of the cavities 300 b) are respectively provided with connection holes 301 adapted to both ends of the shaft 160 of the flywheel module 100. Both ends of the shaft 160 of the flywheel module 100 are respectively fixed in two opposite coupling holes 301 in the housing 300.

Wherein, the cross-section of both ends of the shaft 160 and the cross-sectional shape of the connection hole 301 may be the same. For example, the cross-section of both ends of the shaft 160 is circular, and the cross-section of the connection hole 301 is also circular. In some embodiments, the two ends of the shaft 160 are sleeved with the ring gear 130, the connecting holes 301 are matched with the ring gear 130, and the ring gear 130 can be sleeved in the connecting holes 301 and fixed in the connecting holes 301. In some embodiments, the two ends of the shaft 160 may further include ball bearings 140, which are disposed on the edges of the shaft 160, in addition to the ring gear 130, so that the connection holes 301 are matched with the ball bearings 140, and the ball bearings 140 may be inserted into the connection holes 301 and fixed in the connection holes 301.

In addition, the dc motor 210 may be fixed in the junction of the cylindrical cavity 300b and the platform 300 a. The connection has a certain radian, which is convenient for accommodating the direct current motor 210. In this way, the flywheel module 100 located in the cylindrical cavity 300b can transmit the kinetic energy to the dc motor 210 located at the joint along the direction that the cylindrical cavity 300b points to the platform 300a, and the dc motor 210 converts the received mechanical kinetic energy into electric energy and transmits the electric energy to the device to be charged located on the platform 300a along the aforementioned direction. Therefore, in the process of energy transmission, the energy loss is reduced, and the utilization efficiency of the energy is improved.

In some embodiments, as shown in fig. 1 and 9, fig. 9 is a schematic structural view of a flat gear slide 170 provided by an embodiment of the present invention. Housing 300 also includes rails 320 and flat gear slide 170. Wherein two opposite openings are provided on the side inside the cylindrical cavity 300b, and the rail 320 passes through one opening on the side of the cylindrical cavity 300b, passes through the ring gear 130 and passes out through the other opening on the side. The flat gear slide belt 170 can pass through one opening on the side of the cylindrical cavity 300b, slide on the rail 320 and pass out through the other opening, and the surface of the flat gear slide belt 170 is provided with the ejection gears 171 which are evenly distributed over most of the surface of the slide belt. During the sliding of the flat gear slide belt 170 on the rail 320, the eject gear 171 on the flat gear slide belt 170 engages with the ring gear 130.

As shown in fig. 10, fig. 10 is a schematic diagram of the flywheel module 100 pulled by the flat gear sliding belt 170 according to the embodiment of the present invention. The flat gear slide belt 170 moves in the direction of the straight arrow, and since the eject gear 171 on the flat gear slide belt 170 is engaged with the ring gear 130, the ring gear 130 can be driven by the eject gear 171 and rotate in the direction of the clockwise rotation arrow in fig. 10, and the flywheel module 100 rotates in the direction of the clockwise rotation arrow.

As shown in FIG. 8, the track 320 in the housing 300 may be formed by an upper interior wall 320-u and a lower interior wall 320-d. The lower interior wall 320-d may define a notch 320-c (shown in FIG. 8) at a location past the ring gear 130. The eject gear 171 can be ejected from this notch 320-c and engaged with the ring gear 130 when the flat gear slide 170 slides in the track 320. When the eject gear 171 moves forward or backward, the ring gear 130 also moves.

In some embodiments, as shown in FIG. 9, the flat gear slide 170 includes, in addition to the slide having the ejection gear 171, a pull ring 172 that facilitates manual pulling of the slide. The pull ring 172 may be provided at one end of the slider. For example, in the flat gear slide 170 in FIG. 9, the slide and pull ring 172 may be integrally formed.

In some embodiments, referring to fig. 11 and 12, fig. 11 is an assembly schematic of a tie rod module provided by embodiments of the present invention. Fig. 12 is an external structural schematic view of a drawbar module according to an embodiment of the present invention. The drawbar module 1000 further includes a first sleeve 1010-t1 and a second sleeve 1010-t 2. The first sleeve 1010-t1 is fixed vertically at one end of the pull/push rod 1020. The shaft 1010 of the drawbar module passes through the holes of the charging pins (710a,710b), and the charging pins (710a,710b) are fixed to the shaft 1010. Then, one end of the shaft 1010 with the charging pins (710a,710b) is inserted into the first sleeve 1010-t 1. Next, a second sleeve 1010-t2 is inserted over the other end of shaft 1010 with a charging pin (710a,710b), the end of the sleeve also having an end cap assembly 1040 to prevent shaft 1010 from passing through the sleeve. Through the connection of the above structure, when the pull/push rod 1020 is pushed forward or backward, all the components on the shaft 1010 can rotate synchronously around the central axis of the shaft 1010, i.e., the charging pin is driven to rotate.

Second, as shown in FIG. 12, the end cap kit 1040 may also prevent the shaft 1010 from sliding out of the platform 300 a.

In some embodiments, as shown in fig. 13 and 14, fig. 13 and 14 are schematic structural views of a pull-type rotary power platform for placing an electric toy car according to embodiments of the present invention. For two sides of the tie rod module 1000 penetrating through the platform, one side is provided with a connecting hole 1030, and the other side is provided with a protrusion 1041 matched with the connecting hole 1030. The center of the coupling hole 1030 is the same axis as the center of the boss 1041, for example, the same axis as the shaft 1010. Therefore, two or more than two pull-type rotary power platforms can be connected side by side through the structure.

Illustratively, a connecting hole 1030 is formed at a position corresponding to a position where the pull/push rod 1020 does not abut against the platform 300a and the first sleeve 1010-t1 is connected with the pull/push rod 1020. Protrusions 1041 are provided on the surface of end cap kit 1040 of second sleeve 1010-t 2. Thus, the center of the connection hole 1030 and the center of the boss 1041 are located on the same axis, which is the axis of the shaft 1010.

Referring to fig. 15, fig. 15 is a schematic view of the connection of two single-pull rotary power platforms according to the embodiment of the present invention. For two adjacent single-pull rotary power platforms, the boss 1041 of the tie bar module 1000 of one platform 300a is inserted into and fixed to the connecting hole 1030 of the tie bar module 1000 of the other platform 300 a. When the pull/push rod 1020 or the pull/push handle of one of the pull-type rotary power platforms is pushed forwards or backwards, the pull/push rod 1020 or the pull/push handle of all other platforms can be controlled to be pushed forwards or backwards, so that the platforms can charge the devices to be charged simultaneously or release all the devices to be charged simultaneously.

In some examples, a plurality of pull-type rotary power platforms may be connected side-by-side, with a plurality of electric toy vehicles placed on top of the platforms. When charging is finished, the pull/push handle of one platform is pushed forwards, so that the pull/push handles of all platforms can be pushed forwards simultaneously. The charging pins (710a,710b) on all platforms release all of the electric toy vehicles, which are powered and begin driving simultaneously to play the race of the electric toy vehicles.

In some embodiments, the platform for supporting the device to be charged has a slope, such as 15 degrees or 30 degrees, etc. Can conveniently wait that charging device slides away from the platform after being full of the electricity.

In some embodiments, referring to FIG. 28, embodiments of the present invention further include tracks 300-xt for splicing with the end of platform 300 a. The central axis of the platform 300a is coaxial with the central axis of the track 300-xt. This track 300-xt may extend the length of the slidable movement of the device to be charged on the platform. For example, the toy car may be driven along track 300-xt after sliding off platform 300 a. The track 300-xt is spliced with the platform 300a along the arrow direction in fig. 28, and the illustration of the track 300-xt after being spliced with the platform 300a can refer to fig. 29. Further, sliding grooves (300s, 300-st) may be provided at positions on the central axis of the platform 300a and on the central axis of the track 300-xt. As shown in fig. 7, a sliding groove 300s is formed at the end of the platform 300a and on a section of the axial line of the platform 300 a. As shown in FIG. 28, a sliding groove 300-st is provided on the central axis of the track 300-xt. Accordingly, if the bottom of the device to be charged is provided with a guide pin that matches the chute (300s, 300-st), reference may be made to the structure of the guide pin of fig. 30 and the description of the guide pin that follows. When the device to be charged slides on the platform 300a or the track 300-xt, the guide pin of the device to be charged is inserted into the sliding slot, and as the device to be charged slides forward, the guide pin also slides forward along the sliding slot. Thus, for a toy vehicle, the toy vehicle may move forward according to the slot in the track without traveling off the track.

The power supply components may include a capacitor 440 or a rechargeable battery, etc. The surface of the car base 410 is provided with first metal plates (470a,470b) located below the flip-up plate 420 and an opening 490. The first metal plates (470a,470b) are coupled to a drive motor 460, and the drive motor 460 is coupled to the wheels of the toy vehicle through gears. One side edge of the flip-up plate 420 is fixed to the car base 410 by a rotatable shaft, a second metal plate (422,424) is provided at the bottom of the flip-up plate 420, and the power supply part is connected to the second metal plate (422, 424). Wherein the second metal plates (422,424) can be brought into contact with the first metal plates (470a,470b) when the board 420 is turned upward to lie flat, the power supply part can supply power to the driving motor 460. When the vehicle body 410 is placed on a pull-type rotary power platform according to any one of the above embodiments, the hook portion of the charging pin (710a,710b) is moved toward the vehicle body 410 by pushing the pull/push rod forward or backward, so that the hook portion of the charging pin (710a,710b) enters from the opening 490 of the platform and comes into contact with the second metal plate (422, 424). Further, the upward flipping plate 420 is pushed to flip upward, the second metal plate (422,424) is separated from the first metal plate (470a,470b), and the charging pin (710a,710b) of a pull-type rotary power platform is connected with the second metal plate (422, 424). That is, the generator module 200 of the pull-type rotary power platform is connected to the power supply unit of the electric toy vehicle, and the generator module 200 can start generating power and charge the power supply unit of the electric toy vehicle, and enter a charging mode.

Wherein when the first metal plate (470a,470b) is in contact with the second metal plate (422,424), the first metal plate 470a is connected to the second metal plate 422, transmitting a positive "+" current; the first metal plate 470b is connected to the second metal plate 424, and transmits a negative "-" current. When the charging pin (710a,710b) is connected to the second metal plate (422,424), the charging pin 710a is connected to the second metal plate 422, transmitting a positive "+" current; the charging pin 710b is connected to the second metal plate 424 to transmit a negative "-" current.

For the structure of the second metal plates (422,424) of the flip-up plate 420, see fig. 18, 20 to 21. The upturned plate 420 is provided with a hollow groove penetrating the plate surface, and the second metal plates (422,424) are embedded in the hollow groove. The main body of the second metal plates (422,424) is embedded in the bottom plane of the upturned plate 420, the main body being slightly above the bottom plane of the upturned plate 420 or at least flush with the bottom plane of the upturned plate 420. The second metal plates (422,424) are folded at both ends, which may be referred to as a first end and a second end, respectively. The first end is folded upwardly so that the first end of the second metal sheet (422,424) is flush with the upper plane of the upturned sheet 420. Power supply components, such as pins of a capacitor, that flip the surface of the plate 420 upward may be connected to the face of the first end. The second end is also folded upwardly so that a portion of the panel surface of the second end of the second metal sheet (422,424) may be flush with the upper plane of the upturned panel 420 as shown in figure 28. The flat plate surface can support the tail part of the power supply component.

Referring to fig. 20 to 21, when the electric toy car is placed on a pull-type rotary power platform, the charging pins (710a,710b) abut against the second metal plates (422,424) and push the upward turning plate 420 to turn upward. The direct current motor 210 in the pull-type rotary power platform transmits current to the capacitor 440 through the conducting wires (212a, 212b), the charging pins (710a,710b) and the second metal plates (422,424) in sequence, and the capacitor 440 is charged.

As shown in fig. 23, the power generation process of the generator module 200 of the platform is as follows: the flat gear slide 170 is inserted through one opening of the rail 320 of the housing 300, slides along the rail 320, and exits through the other opening of the rail 320. After the flat gear slide 170 is inserted into the housing 300, a child's finger may snap into the pull ring 172 of the flat gear slide 170 and pull the flat gear slide 170 quickly and forcefully, pulling the flywheel module 100 to rotate and turn the shaft of the dc motor 210. The dc motor 210 begins to generate electricity and transmit current to the power components of the electric toy vehicle.

Further, the hook portions of the charging pins (710a,710b) are moved away from the car base 410 by pushing the pull/push rod 1020 forward or backward, the hook portions of the charging pins (710a,710b) gradually come out of the opening of the platform 300a, and the flip-up plate 420 moves downward as the hook portions of the charging pins (710a,710b) move downward. When the hook portions of the charging pins (710a,710b) completely come out of the openings of the platform 300a, the flip-up plate 420 is laid flat, and the hook portions of the charging pins (710a,710b) are no longer in contact with the second metal plates (422,424), and the second metal plates (422,424) are again in contact with the first metal plates (470a,470 b). At this time, the power supply unit may supply power to the driving motor 460 of the electric toy car, and the car may run forward. Thereby, the change from the charging mode to the normal mode is achieved. In the normal mode, the power supply unit of the electric toy vehicle is connected to the driving motor 460 of the electric toy vehicle, current is transmitted from the power supply unit to the driving motor 460, the driving motor 460 starts to rotate the wheels of the vehicle, and the vehicle will be driven out from a pull type rotary power platform.

Referring to fig. 24 to 27, the process from the start of charging to the stop of charging of the electric toy car is illustrated. The user places the electric toy car on a pull-type rotary power platform, and since the charging pins (710a,710b) protrude from the openings in the surface of the platform, the charging pins (710a,710b) abut against the second metal plates (422,424) of the electric toy car and push the flip-up plate 420 to flip upward. If the DC motor 210 in a pull-type rotary power platform generates electricity, the current is transmitted to the capacitor 440 through the conducting wires (212a, 212b), the charging pins (710a,710b) and the second metal plates (422,424) in sequence, and the capacitor 440 is charged.
