In addition, the power source assembly 11 also includes a power source, which is connected to the power shaft 112 and drives the power shaft 112 to rotate. For example, the power source may be a motor 113. The motor 113 is fixed on the frame 111 through screw connections and connected to the power shaft 112. The power shaft 112 is driven to rotate by the rotational power output by the motor 113. In other embodiments, the power source can also be an electromagnetic driver, an engine, or other devices that can provide rotational power for the power shaft 112, which will not be described again here.

The transmission assembly 121 is disposed on the power shaft 112 and can rotate with the power shaft 112 . Specifically, the transmission component 121 and the power shaft 112 are connected through a key-slot matching structure. The middle part of the transmission component 121 is provided with an axially penetrating through hole. The hole wall of the through hole is provided with a keyway.

The first power output wheel 122 can provide the torque generated by the power source assembly 11 to The strength training machine meets the needs of the power source assembly 11 as a resistance source of the strength training machine. In addition, if the trainer wants to use the treadmill for aerobic training, he can operate the shift actuator 13 again to switch the shift actuator 13 to the first gear state. The shift actuator 13 only communicates with the first power output wheel. 122 stops to fit. At this time, the first power output wheel 122 cannot rotate, and the rotational power output by the power shaft 112 can only be transmitted to the second power output wheel 123 through the transmission assembly 121. At this time, the power source assembly 11 is started, and the power shaft 112 The transmission assembly 121 and the second power output wheel 123 can be driven to rotate. The second power output wheel 123 cooperates with the treadmill transmission to provide the power generated by the power source assembly 11 to the treadmill, so that the power source assembly 11 can be used as a running machine. The power source of the machine is needed.

That is to say, compared with the prior art, the shift driving device 10 of this solution can achieve the requirements of the first training machine 20 and the second training machine 20 by only providing one power source assembly 11 by reversing and stopping the power output mechanism 12.

The groove wall limit fit of 13122a can effectively control the up and down swing trajectory and path of the second shift lever 1312a, so that after the first shift connection component 132 is pressed down and stops with the first power output wheel 122, the second shift lever 1312a is stopped and matched. The gear connection component 133 can be synchronously lifted to separate from the second power output wheel 123 (or after the second gear shift connection component 133 is pressed down to engage with the second power output wheel 123, the first shift connection component 123 can being synchronously lifted and separated from the first power output wheel 122), while limiting the up and down swing stroke of the second shift lever 1312a from being too large, when the first shift connection assembly 132 is lifted and separated from the first positioning groove 1222 , but is still plugged into the first through hole 111a. Similarly, when the second shift connection component 133 is separated from the second positioning groove 1232, it is still plugged into the second through hole 111b, which not only ensures that the gear position is stable and reliable, At the same time, the moving stroke of the second shift lever 1312a when shifting gears again can be reduced, thereby improving operation effectiveness.

In some embodiments, the rotating base assembly 1312 includes a rotating base 13121, a mounting shaft 13122, and a torsion spring 13123. The frame 111 is provided with a protruding column 111c.

In the hole, the second shift lever 1312a is positioned at the current gear, ensuring reliable connection between the second shift connection component 133 and the second power output wheel 123.

Furthermore, by providing the torsion spring 13123, the second shift lever 1312a always has a tendency to twist in one direction, which is the direction in which the limiting column 1312c moves toward the limiting support plate 1312b. This arrangement makes it so that when the shift connection component on either side is plugged into the positioning slot, the second shift lever 1312a drives the limiting post 1312c under the action of the torsion spring 13123 to insert into the corresponding first limiting hole 13121b or the second limiting hole. hole 13122b to limit the up and down swing of the second shift lever 1312a to achieve reliable insertion between the shift connection component and the positioning groove.

The second positioning pin 134e is limitedly engaged with the second connection base 134d. Therefore, under the elastic thrust of the second elastic member 134f, the second positioning pin 134e always has the momentum to extend out of the second connection seat 134d, so that once the first shift connection component 132 is aligned with the first through hole 111a or the second After the second shift connection component 133 is aligned with the second through hole 111b, the second positioning pin 134e can automatically pass through the first through hole 111a and be inserted into the first positioning groove 1222 or pass through the second through hole 111b and be inserted into the second positioning slot. In the groove 1232, the automation level and switching efficiency of the gear shifting operation are improved. Further, if the first shift connection component 132 or the second shift connection component 133 is pressed, the second positioning pin 134e is not accurately inserted into the first positioning groove 1222 or the second positioning groove 1232, but is in contact with the two adjacent ones. The protrusions between the first positioning groove 1222 or two adjacent second positioning grooves 1232 are in contact. At this time, the second positioning pin 134e will retract into the second connecting seat 134d. When the first power output wheel 122 or the second When the power output wheel 123 rotates, the second positioning plug 134e can be inserted into the first positioning groove 1222 or the second positioning groove 1232 under the elastic force of the second elastic member 134f to achieve insertion positioning.
