[0043] The starting device 100 also includes a first torsion spring 4 and a one-way bearing 5. A first fixed shaft 12 is connected to the outer housing 1, and the pusher plate 2 is mounted on the first fixed shaft 12. The first gear 3 is mounted on the first fixed shaft 12 via the one-way bearing 5. The first gear 3 has a gear seat 31 with a retaining groove 32 for receiving the first torsion spring 4. One end of the first torsion spring 4 is connected to the first gear 3, and the other end is connected to the pusher plate 2. The first gear 3 drives the pusher plate 2 to rotate via the first torsion spring 4.

[0044] The electric starting assembly 6 includes a second gear 61, which is in transmission connection with the first gear 3 and is used to drive the first gear 3 to rotate; a driving mechanism 63 (see Figure 1b ) is connected to the second gear 61 for driving the second gear 61 to rotate. The second gear 61 can be directly engaged with the first gear 3 or connected through other gears.

[0045] The motor 631 has an output shaft end 6311 , and the second gear 61 is sleeved and fixedly connected to the output shaft end 6311 for outputting torque and being able to move along with the output shaft end 6311 ; in one embodiment, the output shaft end 6311 is set downward, and the second gear 61 is located below the motor 631 .

[0046] The motor 631 has positive and negative electrodes 6312 and a power source 632 (see Figure 1b ) through the positive and negative poles of the start switch 636 (see Figure 1a ) are connected.

[0047] The motor 631 is connected to the second fixed shaft 14. The electric starting assembly 6 also includes a third gear 62, which is rotatably mounted on the second fixed shaft 14. The third gear 62 can be made by an oil-containing powder metallurgy process, so that the third gear 62 can be rotatably mounted on the second fixed shaft 14.

[0048] The third gear 62 includes a first gear 621 and a second gear 622 coaxially arranged, the first gear 621 meshing with the first gear 3; the second gear 622 meshing with the second gear 61. In one embodiment, the third gear 62 is a double gear, that is, the first gear 621 and the second gear 622 are made into one piece. Among them, the first gear 621 and the second gear 622 can be a split structure or can be integrally formed. The pitch circle diameter of the first gear 621 is smaller than the pitch circle diameter of the second gear 622. In one embodiment, the first gear 621 and the second gear 622 are both made of oil-containing powder metallurgy material.

[0049] The electric starter assembly 6 further includes a retaining ring 65 and a washer 64, which can limit the movement of the third gear 62 along the axis of the second fixed shaft 14. A groove 142 is provided on the second fixed shaft 14, which matches the retaining ring 65 and is used to accommodate the retaining ring 65.

[0050] The second fixed shaft 14 is fixed to the motor 631 via the cover plate 18, wherein the gasket 64 is sandwiched between the third gear 62 and the cover plate 18. The cover plate 18 and the second fixed shaft 14 may be integrally formed or fixed by welding.

[0051] The cover plate 18 has a fourth mounting hole 182, through which the output shaft end 6311 of the motor 631 passes. The motor 631 is fixed to the top surface of the cover plate 18. The fourth mounting hole 182 is a through hole, and the diameter of the fourth mounting hole 182 is greater than or equal to the outer diameter of the output shaft end 6311.

[0052] The hand start assembly 7 further includes a rope pulley 72 , which is in transmission connection with the first gear 3 ; a rope 73 has one end connected to the operating handle 71 and the other end connected to the rope pulley 72 .

[0053] The manual start assembly 7 further includes a ratchet mechanism, and the rope pulley 72 is transmission-connected to the first gear 3 via the ratchet mechanism.

[0054] The ratchet mechanism includes a ratchet wheel 74, a pawl seat 75, a first pawl 76, and a second pawl 77. The ratchet wheel 74 is fixed to the first gear 3 and sleeved on the first fixed shaft 12. The pawl seat 75 is rotatably sleeved on the first fixed shaft 12 or rotatably connected to the outer shell 1. The rope pulley 72 is sleeved outside the pawl seat 75 to drive the pawl seat 75 to rotate. The first pawl 76 is hinged to the pawl seat 75. The second pawl 77 is hinged to the pawl seat 75. The first pawl 76 and the second pawl 77 can be of the same structure and are used to prevent the ratchet wheel 74 from rotating in one direction and not in the opposite direction.

[0055] The manual activation assembly 7 further includes a second torsion spring 761 and a third torsion spring 771. The second torsion spring 761 has one end connected to the pawl seat 75 and one end connected to the first pawl 76. The third torsion spring 771 has one end connected to the pawl seat 75 and one end connected to the second pawl 77. The second torsion spring 761 and the third torsion spring 771 may have the same structure and are used to reset the first pawl 76 and the second pawl 77, respectively.

[0056] Manual activation assembly 7 also includes a return spring 78, which is disposed within outer housing 1 and connected to outer housing 1 at one end and to pawl seat 75 at the other. Return spring 78 is used to maintain rope 73 wrapped around pulley 72. When rope 73 remains wrapped around pulley 72, operating handle 71 adheres to the outer surface of outer housing 1.

[0057] In one embodiment, the components of the starting device 100 may be made of nylon plastic or metal, which has higher durability.

[0058] During an operation, the operating handle 71 is quickly pulled, and the operating handle 71 drives the rope 73 from the first hole 16 (see Figure 1a ) is pulled out, the rope 73 overcomes the elastic force of the reset leaf spring 78 to drive the pulley 72 to rotate and cause the reset leaf spring 78 to deform, and the rotation of the pulley 72 causes the pawl seat 75 to swing, and the ratchet mechanism rotates the ratchet 74 under the action of the first pawl 76. The rotation of the ratchet 74 drives the first gear 3 to rotate, overcoming the torsion of the first torsion spring 4. When the torsion of the first torsion spring 4 is greater than the resistance of the pusher plate 2, the pusher plate 2 rotates, thereby starting the engine.

[0059] During an operation, when the operating handle 71 is released, the return leaf spring 78 returns to its original state when the external force is lost, thereby driving the rope pulley 72 to rotate. The rotation of the rope pulley 72 causes the rope 73 to be wound around the rope pulley 72. At this time, the ratchet mechanism inside the rope pulley 72 and the first gear 3 slip against each other. The first gear 3 is fixed and does not rotate under the action of the one-way bearing 5, thereby preventing the pusher plate 2 from rotating, thereby preventing the engine from being started by mistake.

[0060] During an operation, press the start switch 636 (see Figure 1a ), the output shaft end 6311 of the motor 631 drives the second gear 61 to rotate and output torque, the second gear 61 drives the second linked gear 622 of the third gear 62 to rotate, the first linked gear 621 of the third gear 62 rotates along with the second linked gear 622 and drives the first gear 3 to rotate, the first gear 3 overcomes the torsion force of the torsion spring, and when the torsion force of the first torsion spring 4 is greater than the resistance of the pusher plate 2, the pusher plate 2 rotates, thereby starting the engine.

[0061] The present application adds a ratchet mechanism and a one-way bearing 5, so that the pusher plate 2 can only rotate normally in one direction and cannot rotate in the reverse direction, thereby avoiding the situation of accidentally starting the engine.

[0062] Please refer to Figure 3 , which is a partial structural diagram of a starting device 100 according to an embodiment of the present application. The ratchet 74 and the first gear 3 are coaxially arranged and made into one piece, so that the rotation of the ratchet 74 can drive the rotation of the first gear 3.

[0063] A circular winding groove 721 is provided in the middle of the outer wall of the rope pulley 72 for receiving the wound rope 73. A connecting hole 722 is provided on the inner bottom surface of the winding groove 721. When one end of the rope 73 passes through the connecting hole 722, it can be fixed to the rope pulley 72. In one embodiment, the rope pulley 72 and the pawl seat 75 can be made into one piece.

[0064] The first gear 3 is provided with a fourth mounting hole 33 matched with the one-way bearing 5. In one embodiment, the one-way bearing 5 is a hexagonal one-way bearing, and the fourth mounting hole 33 is a hexagonal hole.

[0065] The ratchet 74 is provided with a fifth mounting hole 741 which passes through the ratchet 74 ; the pawl seat 75 is provided with a mounting platform 751 which matches the fifth mounting hole 741 ; and the mounting platform 751 is provided with a sixth mounting hole 752 which passes through the pawl seat 75 .

[0066] Please refer to Figure 4a, which illustrates the motion of a ratchet mechanism according to one embodiment of the present application when pulley 72 rotates counterclockwise. When operating handle 71 is pulled, pulley 72 rotates counterclockwise, causing pawl seat 75 to swing counterclockwise. This causes first pawl 76 and second pawl 77 to engage the teeth of ratchet wheel 74, causing ratchet wheel 74 to rotate a certain angle. This, in turn, causes first gear 3 to rotate, which in turn causes pusher plate 2 to rotate, thereby starting the engine.

[0067] Please refer to Figure 4b , which is a schematic diagram of the ratchet mechanism according to one embodiment of the present application, showing the movement of the rope pulley 72 when it rotates clockwise. When the operating handle 71 is released, the rope pulley 72 rotates clockwise, causing the pawl seat 75 to swing clockwise. The first pawl 76 and the second pawl 77 are able to slide over the backs of the teeth of the ratchet wheel 74. Therefore, the ratchet wheel 74 is stationary, and the first gear 3 is also stationary.

[0068] Please refer to Figure 5 , which is a cross-sectional view of a starting device 100 according to one embodiment of the present application. A first mounting hole 11 is defined in the outer shell 1, and a first fixed shaft 12 is fixed within the first mounting hole 11 and cannot rotate. In one embodiment, the outer shell 1 is a plastic component, and the first fixed shaft 12 is nested within the first mounting hole 11, or the outer shell 1 and the first fixed shaft 12 are integrally formed. The outer shell 1 and the first fixed shaft 12 can be made of the same material or multiple different materials.

[0069] A cylindrical boss 17 is provided on the outer housing 1 at the first mounting hole 11 and is coaxial with the first fixed shaft 12. The pawl seat 75 is rotatably mounted on the boss 17 through the sixth mounting hole 752. The diameter of the sixth mounting hole 752 matches the outer diameter of the boss 17, forming a clearance fit. This allows the boss 17 to restrict the movement of the pawl seat 75 in the forward, backward, left, and right directions, but does not restrict the rotation of the pawl seat 75 about its own axis.

[0070] The shifter plate 2 has a third mounting hole 21 and a seventh mounting hole 23. The third mounting hole 21 is a stepped through-hole with a stepped surface 22. The shifter plate 2 is mounted on the top of the first fixed shaft 12 through the third mounting hole 21. The diameter of the third mounting hole 21 matches the outer diameter of the top of the first fixed shaft 12, forming a clearance fit. This allows the first fixed shaft 12 to restrict the movement of the shifter plate 2 in the forward, backward, left, and right directions, but cannot restrict the rotation of the shifter plate 2 about its own axis. The first torsion spring 4 is disposed in the seventh mounting hole 23 and is connected to the shifter plate 2.

[0071] The starting device 100 further includes a screw 8 , which passes through the third mounting hole 21 and is threadedly connected to the first fixed shaft 12 . The screw 8 can abut against the step surface 22 , thereby limiting the upward and downward movement of the finger plate 2 .

[0072] The outer shell 1 is provided with a second mounting hole 13, and the second fixed shaft 14 is disposed in the second mounting hole 13. The second mounting hole 13 is used to limit the movement of the second fixed shaft 14. The diameter of the second mounting hole 13 is greater than or equal to the outer diameter of the second fixed shaft 14.

[0073] In one embodiment, a cover 6313 is further provided outside the motor 631, and a fourth hole 63131 is provided on the cover 6313, and the fourth hole 63131 is a through hole; a third hole 181 is provided on the cover plate 18, and the third hole 181 is a through hole; a third mounting hole 19 is provided on the outer shell 1, and the third mounting hole 19 is a threaded hole. The starting device 100 also includes a second bolt 185, and the second bolt 185 passes through the fourth hole and the third hole 181 in sequence, and is threadedly connected to the third mounting hole 19.

[0074] During an operation, the output shaft end 6311 of the motor 631 is first passed through the fourth mounting hole 182 and then through the first bolt 183 (see Figure 2 ) Fix the motor 631 on the cover 18, then fix the second gear 61 on the output shaft end 6311, put the third gear 62 on the second fixed shaft 14, then turn over the motor 631, cover the cover 18 on the outer shell 1, insert the second fixed shaft 14 into the second mounting hole 13, and then pass the second bolt 185 through the fourth hole, the third hole 181 and the third mounting hole 19 in sequence, so that the cover 6313, the motor 631 and the cover 18 are fixed to the outer shell 1.

[0075] Please refer to Figure 6 and Figure 7 , which is a partial structural diagram of a starting device 100 according to an embodiment of the present application. The second gear 61 is mounted on the output shaft 6311 of the motor 631. The second gear 61 meshes with the second connecting gear 622 of the third gear 62. The first connecting gear 621 of the third gear 62 meshes with the first gear 3. The ratchet 74 and the pusher plate 2 are respectively disposed on the upper and lower sides of the first gear 3.

[0076] Please refer to Figure 8 , which is a partial structural diagram of an electric starting assembly 6 according to an embodiment of the present application.
