The radius of the arc-shaped groove 1131 is the standard center distance of the rocker gear 117 meshing with the middle pinion 112, and the axis center of the middle transmission shaft 113 is the center of the circle, so when the rocker gear 117 drives the middle pinion 112 to rotate, the middle When the pinion gear 112 moves along the track, it still keeps a meshed state with the rocker gear 117 .

A spring 122 is connected between the sector-shaped incomplete large gear 1241 and the housing; one end of the pedal 125 is hinged to the housing, and the other end of the pedal 125 is a movable end; the rocker 124 and the pedal 125 are connected through a connecting rod 126; Between the incomplete large gear 1241 and the rocking bar 124 there is an articulated shaft 1242 hinged to the housing. The articulated shaft 1242 forms a lever mechanism between the sector-shaped incomplete large gear 1241 and the rocking bar 124 . A positioning rod 128 is provided on the middle plate 104, which can mechanically position the lowest position of the rocker 124. As shown in FIG. When the pedal 125 is pressed once, the sector-shaped incomplete large gear 1241 drives the rocker pinion 115 to rotate forward for one revolution, and the corresponding coaxial rocker gear 117 of the rocker pinion 115 also rotates forward for one revolution; the spring drives the rocker 124 to press down Returning once, the sector-shaped incomplete bull gear 1241 reversely drives the rocker pinion 115 to rotate one revolution, and the corresponding coaxial rocker bull gear 117 of the rocker pinion 115 also reversely rotates one circle. The housing is provided with an intermediate plate 104 fixed to the housing. The gear set is located on one side of the intermediate plate, and the front generator 101, rear generator 130, front bevel gear 103, and rear bevel gear 129 are located on the other side of the intermediate plate. side; the front generator 101 and the rear generator 130 are fixed on the middle plate; the shafts of each gear are fixed on the housing or the middle plate.

When the pedal 125 is pressed down, the rocker 124 is pressed down by the connecting rod 126 to drive the sector-shaped incomplete large gear 1241 to swing upwards, thereby driving the rocker pinion 115 meshed with the sector-shaped incomplete large gear 1241, and then through the rocker large gear 117 Drive the middle pinion 112 to rotate, at this time the middle pinion 112 is subjected to the action force of the rocker big gear 117, and the interlocking transmission shaft 113 moves backward in the arc-shaped groove 1131 until the middle big gear 111 meshes with the next-stage transmission pinion 114 Live and continue to drive the rear stage transmission pinion 114 to rotate, thereby the rear stage transmission bull gear 119 coaxial with the rear stage transmission pinion 114 drives the rear stage two transmission pinion 121 to rotate, and then the rear stage two transmission pinion 121 rear There is a rear bevel gear 129 meshed with the rear secondary transmission pinion 121, and the rear bevel gear 129 meshes with the rear generator bevel gear 131 to drive the rear generator 130 to rotate;

When the pedal 125 loses the downward force, the spring 122 drives the down-pressing rocker 124 to return and drives the sector-shaped incomplete large gear 1241 to swing downward, so that the rocking rod large gear 117 drives the middle pinion 112 to rotate. Due to the force of the large rocker gear 117, the linkage transmission shaft 113 moves forward in the arc-shaped groove 1131 until the middle large gear 111 meshes with the previous transmission pinion 108 and continues to drive the previous transmission pinion 108 to rotate; thus The front-stage transmission bull gear 105 coaxial with the previous-stage transmission pinion 108 drives the front-stage transmission pinion 107 to rotate, and the front stage of the front-stage transmission pinion 107 is provided with a front wheel meshing with the front-stage transmission pinion 107. Bevel gear 103, front bevel gear 103 meshes with front generator bevel gear 102, drives front generator 101 to rotate and work. When the middle bull gear 111 meshes with the rear stage transmission pinion 114, the middle bull gear 111 does not contact with the previous stage transmission pinion 108. The rear stage transmission pinion 114 does not contact, so that the transmission of the previous stage transmission pinion 108 and the rear stage transmission pinion 114 does not interfere with each other.

A pedal power generating device 100 is respectively installed under the adjustable feet 301 on both sides of the bracket 303, and each of the two power generating devices has two generators at the front and rear, so four currents are finally output, and the current in the same direction is drawn through parallel connection. Converge into one road and input the storage battery 210 . As can be seen from the data inquiry, most of the existing pedal power generating devices only utilize the energy of stepping on the pedal, and ignore the energy of lifting, and only allow it to reset with a spring, and prevent reverse deceleration with the corresponding transmission mechanism. However, the present invention can simultaneously utilize the energy of stepping on and lifting the pedal to improve the utilization rate of energy.

It can be seen from the above structural records that the transmission of the gear set driven by the pedal 125 is realized through a four-bar mechanism, which includes the pedal 125, the connecting rod 126, the rocker 124, and the middle plate 104. The four-bar mechanism makes the structure more stable. Compact and reasonable. If the rocker 124 is directly driven as the pedal 125, the pedal 125 needs a plane as the support of the heel, so that the heel serves as the fulcrum, and the large gear in the corresponding gear train transmission is too large, which will interfere with the structural arrangement. , cannot be made into a plane, so a connecting rod 126 is added to make the position of the pedal 125 higher, which is beneficial to the layout of the transmission system structure. At the same time, the four-bar mechanism is a double rocker mechanism, which can realize the speed increase through the length relationship of the control rods, and by setting the position of the fulcrum reasonably, the force required to press down the pedal 125 can be reduced by using the lever theorem. The positioning rod on the middle plate 104 determines the lowest position of the rocker 124, making it between the dead points of the double rocker mechanism, so as to avoid the phenomenon of jamming when the pedal 125 moves.

Referring to FIGS. 8 to 11 , the blowing device includes a blowing box 203 , a storage battery 210 located in the blowing box 203 , an electric wire 400 , and a fan; the storage battery 210 is connected in parallel with the front generator 101 and the rear generator 130 .

The battery 210, the electric wire 400, the fan, the warm glove 206 above the fan are housed in the blowing box 203, and the electric heater is housed in the warm glove 206. Because the function of blowing in summer and heating in winter is to be realized, it is necessary to utilize a switch to control the work of both. It can be seen that in the circuit shown in Figure 9, the fan and the electric heater are connected in parallel to the circuit, and the two corresponding branches are respectively controlled by two switches. However, because the two switch controls are difficult for children to memorize, and the operation is complicated, the circuit lines are messy in the actual circuit connection, and a control switch 209 with a special structure, that is, a six-pin three-control slide switch, can be used for control. There are two parallel and equal length iron wires inside it, which are located in the button of the switch and can move left and right with the switch. Use this control switch 209, its wiring diagram as shown in Figure 9, realize that switch is moved to the left side, and electric heater works; The layout of the circuit in the blowing box 203 is shown in Figure 11. It can be seen that the blowing box 203 has corresponding threaded holes for fixing and is used to connect the electric wire 400 to the warm glove 206 and connect the electric wire 400 from the The outlet hole for generator access. As shown in FIG. 8 , there are three fans and three electric heaters, namely the right fan 201 , the middle fan 204 , the left fan 208 , the right electric heater 202 , the middle electric heater 205 , and the left electric heater 207 . The three fans are evenly distributed in the blowing box body 203, so that the generated wind force is evenly distributed and sent out along the slot of the box body. The three fans are isolated in the box to avoid direct contact with children. The side of the box body facing children can be provided with a metal grid structure to prevent children from putting their fingers into the box body and improve the safety of use. And three electric heaters are evenly distributed on the inner side of the warmer glove 206, so that the heat produced is distributed evenly along the inner side of the warmer glove 206. The fan and the electric heater are not directly exposed, and the air blowing box 203 and the warm gloves 206 are used to isolate them to ensure the safety of use. At the same time, the blowing box 203 can prevent the fan rotation from being disturbed by external wind force, and the warm gloves 206 can slow down the heat generation Sheet heat dissipation. The electric heater is made of far-infrared carbon fiber material, which is safe and convenient, can generate heat under low pressure, and can be directly installed in the cloth. The output current of the storage battery 210 is output after passing through the voltage stabilizing and step-down circuit, so as to ensure the effective operation of the device.

As shown in FIG. 13 , the storage battery 210 receives the electric energy converted by the kinetic energy of the pedal 125 through the electric wire 400, so the energy can be transmitted over a long distance. , so that it is not cluttered, so that it does not get caught in the bicycle wheel. Because the length of the adjustable stand 301 is adjustable, when the stand is short, the wire 400 can be wound on the support 303 and fixed by the wire clamp 302 . It is also possible to install the wire 400 inside the bracket 303, but it will increase the processing difficulty of the bracket 303, which is not desirable. The device of the invention adds a pedal and a series of transmission structures to the original foot bracket of the child seat on the rear seat of the bicycle, which can generate electricity by stepping on the pedal and play the role of exercising the child's body. Children in this invention have strong participation, and wind and heat are generated as a result, which can further stimulate children's interest. At the same time, the storage battery 210 receives the generated electric energy for the fan or electric heater to work, and the mode can be switched through the control switch 209 on the blower box 203, namely "fan blowing", "shutdown", and "electric heater for heating". Mode, to achieve the purpose of cooling in summer and warming in winter. The adjustable foot stand 301 can be freely extended or shortened, not only to ensure comfort, but also to ensure the convenience of stepping on and lifting the pedal 125 . And the material of seat cushion 304, back cushion 305 and the structure of support 303 all meet the requirement of human comfort.
