[0002] Currently, there are mainly two kinds of starting modes for the hand-pulling starting of mainstream internal combustion engines. One is the starting mode in which a rope wheel directly drives a connecting wheel of the internal combustion engine, which is the most common, has a simple structure, is reliable in work, but is laborious and has a large starting rebound impact. The other is an electric starting mode in which a motor drives the internal combustion engine to run through a speed reduction mechanism, which has a complex structure, is relatively large in size, and has the rebound force of the internal combustion engine acting on the motor driving system through a transmission system, and is prone to causing impact and damage to the transmission system and the motor. In addition, the electric starting device has the disadvantages of poor reliability and poor maintainability. Therefore, in the actual use of the internal combustion engine with the electric starting device, a hand-pulling starting device must be provided to ensure the reliability.

[0026] As an illustration, the manual drive module and the electric drive module can drive the transmission main shaft 10 to rotate, the transmission main shaft 10 drives the disc spring seat 17 to rotate, the energy storage disc spring 18 arranged in the disc spring seat 17 converts the torque into elastic potential energy, when the energy storage disc spring 18 stores the elastic potential energy exceeding the starting resistance of the internal combustion engine, the energy storage disc spring 18 releases the elastic potential energy and converts the elastic potential energy into mechanical energy, and the starting ratchet 19 arranged on the energy storage disc spring 18 is connected with the internal combustion engine transmission wheel 20 to connect the internal combustion engine and realize the starting action of the internal combustion engine.

[0027] Specifically, the electric drive module comprises a motor 14, a detachable battery pack 4, a switch 22 and a second one-way transmission mechanism 23, the switch 22 and the second one-way transmission mechanism 23 are used to control the on-off of the motor 14, and the motor 14 is powered by the detachable battery pack, preferably, the motor 14 can be a direct current motor 14.

[0028] Referring to Figure 7 As shown, the gear transmission unit comprises a primary transmission gear 12, a secondary transmission gear 15 and a secondary planetary gear reducer 13, the motor 14 is connected with the secondary planetary gear reducer 13 and can drive the primary transmission gear 12 to rotate, the primary transmission gear 12 is engaged with the secondary transmission gear 15, and the secondary transmission gear 15 is connected with the transmission main shaft 10.

[0029] Referring to Figure 7 As shown, the motor 14 is turned on through the switch 22 and the second one-way transmission mechanism 23, the power of the motor 14 drives the primary transmission gear 12 to rotate in the S2 direction after being decelerated by the secondary planetary gear reducer 13, and then drives the secondary transmission gear 15 engaged with the primary transmission gear 12 to rotate in the S1 direction and drives the transmission main shaft 10 to rotate.

[0030] Specifically, the gear transmission unit further comprises a one-way roller bearing 15a arranged on the outer periphery of the transmission main shaft 10, and the secondary transmission gear 15 drives the transmission main shaft 10 to rotate through the one-way roller bearing 15a. At this time, a first one-way transmission mechanism 21 is formed among the secondary transmission gear 15, the one-way roller bearing 15a, and the transmission main shaft 10. When the secondary transmission gear 15 rotates in the S1 direction, the one-way roller bearing 15a is locked, so that the secondary transmission gear 15 can drive the transmission main shaft 10 to rotate.

[0031] Referring to Figure 5 As shown in the figure, the manual driving module comprises a starting handle 1, a pull rope 2, a starting disc spring 5, a rope wheel 6, a transmission ratchet wheel 9 group, the pull rope 2 is connected and wound on the rope wheel 6, one end of the pull rope 2 passes through the manual mounting seat 3 and is provided with the starting handle 1, the starting disc spring 5 can drive the rope wheel 6 to reset after rotation, and drive the transmission main shaft 10 to rotate through the transmission ratchet wheel 9 group. After the user pulls the moving handle, the rope wheel 6 rotates in the S1 direction, the starting disc spring 5 tightens, the rope wheel 6 drives the transmission main shaft 10 to rotate in the S1 direction through the transmission ratchet wheel 9 group, and after the user releases the pull rope 2, the elastic potential energy of the starting disc spring 5 is released and the pull rope 2 is recovered. In this way, the transmission main shaft 10 is driven to rotate repeatedly.

When the rope wheel 6 rotates in the S1 direction, the pawl 8 is driven to rotate, and when the starting disc spring 5 drives the rope wheel 6 to rotate in the opposite direction of the S1 direction, the transmission ratchet wheel 9 cannot normally rotate under the action of the pawl 8. In this way, the manual driving module can continuously drive the transmission main shaft 10 to rotate in the S1 direction.

[0033] Through the first one-way transmission mechanism 21, when the electric driving module works, the transmission main shaft 10 cannot drive the manual driving module in the reverse direction through the transmission ratchet wheel 9 group. When the secondary transmission gear 15 drives the transmission main shaft 10 to rotate, the transmission ratchet wheel 9 connected with the transmission main shaft 10 rotates in the S1 direction, and the transmission ratchet wheel 9 and the pawl 8 in the second one-way transmission mechanism are disengaged, so that the transmission ratchet wheel 9 cannot affect the rotation of the rope wheel 6, so as to realize the disengagement of the transmission power and the manual driving device.
