Description

Technical Field

[0001] This utility model belongs to the field of power generation floor technology, and in particular relates to a step-based power generation module. Background Technology

[0002] Existing power generation modules inside power generation floors typically use a unidirectional transmission structure with linkages and gears to drive the motor shaft for power generation. However, traditional linkage transmission mechanisms require multiple links to transmit power sequentially, making the structure complex. Furthermore, the motion characteristics of the linkage mechanism, such as speed and acceleration, change throughout the entire motion cycle. This nonlinearity and speed fluctuation result in significant fluctuations in the voltage and frequency output of the motor. It is necessary to add a variable speed gearbox, frequency converter, or complex control algorithm to obtain the required stable output voltage. In addition, frequent acceleration and deceleration put a significant impact on the transmission components, which can easily cause equipment damage. Summary of the Invention

[0049] Example 1

[0050] Please see Figures 1-9According to Embodiment 1 of this utility model, a pedal-powered generation module includes a pedal 1, a base 2, a lifting bracket 3, a lifting block 4, an elastic lifting structure 5, a gear 6, a one-way rotating shaft transmission structure 7, and a motor 8. The pedal 1 is vertically connected to the base 2 via the lifting bracket 3. The one-way rotating shaft transmission structure 7 and the motor 8 are disposed within the base 2. The lifting block 4 is partially disposed within the base 2, vertically movable via the elastic lifting structure 5, with its top end pressing against the bottom surface of the pedal 1. The one-way rotating shaft transmission structure 7 is connected to the motor shaft of the motor 8. The gear 6 is connected to the one-way rotating shaft transmission structure 7. The side of the lifting block 4 forms a rack structure, which meshes with the gear 6.

[0051] The pedal 1, lifting block 4, gear 6, one-way rotating shaft transmission structure 7, and motor 8 work together to achieve the following: stepping on the pedal 1 drives the gear 6 to rotate, and the gear 6 simultaneously drives the motor shaft in one direction through the one-way rotating shaft transmission structure 7, thus generating electricity by pedaling. The structure is simple. The lifting bracket 3 ensures stable lifting between the pedal 1 and the base 2. The elastic lifting structure 5 is used to reset the lifting block 4.

[0052] The one-way rotating shaft transmission structure 7 includes a first one-way bearing, a transmission shaft 71, several second one-way bearings 72, a buffer spring 73, and a drive sleeve 74.

The drive sleeve 74 is fixedly connected to the outside of the motor shaft. The buffer spring 73 is sleeved outside the transmission shaft 71 and located between the drive sleeve 74 and the gear 6. The transmission shaft 71 circumferentially limits the buffer spring 73 near the first end of the gear 6. The drive sleeve 74 circumferentially limits the second end of the buffer spring 73. The rotating shaft is connected to the drive sleeve 74 via the buffer spring 73.

[0053] The first one-way bearing ensures that when pedaled, gear 6 can only drive the drive shaft 71 to rotate in a preset direction.

[0056] The drive shaft receiving cavity 7421 is used to receive the second end of the drive shaft 71. The inner diameter of the drive shaft receiving cavity 7421 is larger than the outer diameter of the second end of the drive shaft 71 to prevent the rotation of the drive shaft 71 from interfering with the transmission of the drive sleeve 74. The spring limiting groove 7422 is used to circumferentially limit the second end of the buffer spring 73.

[0057] In this embodiment, the motor shaft connecting part 741 has several connecting holes 7412 formed on its side. The motor shaft connecting part 741 is screwed to the motor shaft by set screws passing through the connecting holes 7412.
