Description

Technical Field

[0001] This utility model relates to the field of outboard motor structure technology, and in particular to an outboard motor starter. Background Technology

[0002] An outboard motor is an integrated propulsion system consisting of an engine and a propeller, mounted at the stern of the boat. It is the power heart of the small vessel, its core function being to provide propulsion and control direction. On simple hulls, the small-horsepower outboard motor typically uses a pull-rope manual starter. When the starter rope is pulled quickly and forcefully, the force is transmitted through a mechanism to the crankshaft of the engine, driving the piston to move and thus completing the intake, compression, and ignition process.

[0003] The publication CN220267849U, entitled "A Novel Anti-Abrasion Hand-Pulled Starter," points out that most existing hand-pulled starters lack anti-abrasion devices for the pull rope, causing friction between the pull rope and the starter housing during use. Prolonged use leads to damage to both the pull rope and the housing, reducing the rope's lifespan. The publication proposes an improvement by incorporating a pulley system. This system allows the wire rope to slide back and forth, preventing friction between the wire rope and the housing. While the pulley system rotates on its own, when the wire rope's pulling direction changes, it doesn't compress against the grooves within the pulley system, but rather against the sides of the grooves. This friction still causes damage to the pull rope or the pulley system. Therefore, the publication proposes this improvement. Utility Model Content

[0004] In view of the problems mentioned above, the technical problem to be solved by this utility model is to provide an outboard motor starter.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an outboard motor starter, including a starter housing, a drive rope module integrally formed on the outer side of the housing, an opening at the outer end of the drive rope module communicating with the interior of the housing, and a protective part installed inside the opening, the protective part including:

[0006] The sleeve, installed inside the pipe opening, serves as the channel for the drive rope;

[0007] The pulley section has two sets, and the pulley section itself can be rotated circumferentially, and is respectively set at both ends of the sleeve;

[0008] The sealing part is located inside the sleeve and can move along the sleeve axis to control the opening and closing of the sleeve.

[0009] A further preferred embodiment of this utility model is: the outer end of the sleeve has an integral extension edge, the extension edge is supported on the outside of the tube opening, and the outer end of the tube opening is fitted with an outer end cap for squeezing the extension edge, the outer end cap being detachably fixed to the outside of the drive rope module.

[0010] A further preferred embodiment of this utility model is: the pulley part includes a limiting ring fixed inside the sleeve, two sets of brackets slidably disposed with the limiting ring, and pulley one and pulley two disposed between the two sets of brackets;

[0011] Pulley 1 and Pulley 2 are used to clamp the drive rope.

[0012] A further preferred embodiment of this utility model is: two sets of brackets are symmetrically arranged and both abut against the outside of the limiting ring. The two sets of brackets abut against one side of the limiting ring and a clamping block is fixed by bolts. The limiting ring is clamped between the brackets and the clamping block. The brackets and the clamping block can rotate along the limiting ring.

[0013] Both pulley one and pulley two are rotatably installed between the two sets of brackets.

[0014] A further preferred embodiment of this utility model is as follows: the diameter of pulley one is larger than the diameter of pulley two, pulley two is fastened inside pulley one, and the end of pulley two abuts against the inner wall of the groove side of pulley one, there is a gap between pulley one and pulley two through which the driving rope passes, and the gap between pulley one and pulley two is offset from the axis of the sleeve.

[0015] A further preferred embodiment of this utility model is: the sleeve has an integral inner protrusion layer, which is arranged in a circle along the axis of the sleeve. The sealing part is blocked in the inner protrusion layer. When the sealing part moves outward along the inner protrusion layer, a hole is generated inside the inner protrusion layer for the drive rope to pass through. When the sealing part moves inward along the inner protrusion layer, the inner protrusion layer clamps the drive rope.

[0016] A further preferred embodiment of this utility model is: the sealing part includes a cylindrical rubber plug with a through hole inside. A section of the rubber plug used for pressing against the inner protruding layer has a slit that divides the rubber plug. When the rubber plug is pressed against the inner protruding layer, the slit closes and the through hole clamps the drive rope.

[0017] A further preferred embodiment of this utility model is: a support ring is fixed to the outward end of the rubber stopper, the outer arc surface of the support ring is in contact with the inner wall of the sleeve, and a control rod extending out of the sleeve is fixed to the outer end face of the support ring.

[0018] A further preferred embodiment of this utility model is that the cross-section of the inner protruding layer is set as an arc.

[0019] A further preferred embodiment of this utility model is: the slit gradually narrows from the outside to the inside, and when the end of the rubber stopper with the slit is pressed against the inner protruding layer, the slit is sealed.

[0020] Compared with the prior art, the advantages of this utility model are:

[0021] 1. Pulley 1 and Pulley 2 in the pulley section can be used as a whole and rotate freely around the limit ring with the bracket. When the operator pulls the drive rope at different angles, the pulley group can automatically rotate and adjust to the position that best matches the direction of the pulling force, ensuring that the drive rope is always well supported by Pulley 2 and rolls smoothly.

[0022] 2. The gap between pulley one and pulley two is intentionally offset from the sleeve axis. When under force, it can actively apply a torque to the pulleys, causing the pulley block to rotate to the corresponding position faster and more accurately, which greatly reduces the sliding friction between the drive rope and pulley one and pulley two caused by improper angle.

[0023] 3. When the starter is not working, the rubber plug is in a compressed state. The inner side of the rubber plug holds the drive rope tightly, and the outer side is squeezed against the inner protruding layer to achieve a sealing effect, effectively preventing external water from entering the starter. When working, the rubber plug is released from compression, and the slit and through hole open to provide sufficient space for the drive rope to move. Attached Figure Description

Detailed Implementation

[0034] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0035] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0036] This embodiment mainly describes the outboard motor starter; please refer to [link / reference needed]. Figures 1-8 Specifically, the existing outboard motor starter's drive rope rubs against the housing 1 when pulled, causing damage to the drive rope or pulley system. Furthermore, the drive rope module 2 can allow water to seep into the starter, affecting its lifespan. Therefore, this outboard motor starter is proposed, comprising a housing 1, with a drive rope module 2 integrally formed on the outer side of the housing 1. The outer end of the drive rope module 2 has a port 21 communicating with the interior of the housing 1. A protective part 3 is installed inside the port 21, and the protective part 3 includes:

[0037] The sleeve 32 is installed inside the pipe opening 21 and serves as a channel for the drive rope;

[0038] The pulley section 4 is provided in two sets. The pulley section 4 itself can be rotated, and is respectively provided at both ends of the sleeve 32.

[0039] The sealing part 5 is disposed inside the sleeve 32. The sealing part 5 can move along the axis of the sleeve 32 and is used to control the opening and closing of the sleeve 32.

[0040] Specifically, the outboard motor starter is existing technology, comprising a housing 1, a drive rope module 2 integral with the housing 1, and a protective section 3 within the drive rope module 2. The protective section 3 allows the drive rope to pass through, and the pulling of the drive rope drives the outboard motor. It should be noted that the protective section 3 includes a sleeve 32 through which the drive rope passes, two sets of pulleys 4 located at both ends of the sleeve 32, and a sealing section 5 located inside the sleeve 32. When the starter is not working, the sealing section 5 is in a sealed state. The pulleys 4 support the drive rope, and when the drive rope is pulled, the pulleys 4 rotate, preventing wear on the drive rope or the pulleys 4. It should also be noted that the pulleys 4 are rotatable and their positions adjustable. When the drive rope is pulled in different directions, the pulleys 4 automatically adjust their positions to prevent wear on the drive rope or the pulleys 4.

[0041] like Figure 4 As shown, the outer end of the sleeve 32 has an integral extension edge 33, which is supported on the outside of the tube opening 21. The outer end of the tube opening 21 is fitted with an outer end cap 31 for squeezing the extension edge 33. The outer end cap 31 is detachably fixed to the outside of the drive rope module 2.

[0042] Specifically, the sleeve 32 is limited by the outer end cover 31, which is detachable, making it easy to install and remove the sleeve 32 and to replace the pulley part 4 and the sealing part 5.

[0043] like Figure 5 and Figure 6 As shown, the pulley section 4 includes a limiting ring 41 fixed inside the sleeve 32, two sets of brackets 42 slidably disposed with the limiting ring 41, and a pulley 44 and a pulley 45 disposed between the two sets of brackets 42.

[0044] Pulley 44 and pulley 45 are used to clamp the drive rope.

[0045] Specifically, pulley 44 and pulley 45 clamp the drive rope, and the two sets of brackets 42 can rotate. When the drive rope is pulled in different directions, pulley 44 and pulley 45 can rotate to different directions, corresponding to the direction of the drive rope, to ensure that the drive rope is supported on pulley 45 and that the drive rope runs smoothly.

[0046] like Figure 5 and Figure 6 As shown, the two sets of brackets 42 are symmetrically arranged and both abut against the outside of the limiting ring 41. The two sets of brackets 42 abut against one side of the limiting ring 41 and a clamping block 43 is fixed by bolts. The limiting ring 41 is clamped between the brackets 42 and the clamping block 43. The brackets 42 and the clamping block 43 can rotate along the limiting ring 41.

[0047] Both pulley 44 and pulley 45 are rotatably installed between the two sets of brackets 42.

[0048] Specifically, the bracket 42 cooperates with the clamping block 43 to clamp the limiting ring 41 outward. The clamping block 43 has a threaded rod that passes through the bracket 42 and is fixed by a nut, which facilitates the limiting of the two sets of brackets 42 and the limiting ring 41.

[0049] like Figure 6 As shown, the diameter of pulley 44 is larger than that of pulley 45. Pulley 45 is fastened inside pulley 44, and the end of pulley 45 abuts against the inner wall of the groove side of pulley 44. There is a gap between pulley 44 and pulley 45 through which the drive rope passes. The gap between pulley 44 and pulley 45 is offset from the axis of sleeve 32.

[0050] Specifically, pulley 44 and pulley 45 are engaged, with a gap between them for the drive rope to pass through. When the drive rope passes through this gap, its position is not aligned with the axis of sleeve 32, but parallel to it. It's important to understand that when the drive rope is pulled, its position does not directly align with the axis of sleeve 32. Manual pulling will inevitably cause a positional deviation. As the drive rope passes through the gap between pulleys 44 and 45, this deviation causes pulleys 44 and 45 to rotate, oriented in different positions. This ensures the drive rope is supported on pulley 45. It should also be noted that... Figure 8 The figure shows the end face view of pulley 44 and pulley 45. The gap between pulley 44 and pulley 45 is offset from the axis of sleeve 32.

[0051] like Figure 5 As shown, the sleeve 32 has an integral inner protrusion layer 34. The inner protrusion layer 34 is arranged in a circle along the axis of the sleeve 32. The sealing part 5 is blocked in the inner protrusion layer 34. When the sealing part 5 moves outward along the inner protrusion layer 34, a hole is generated inside the inner protrusion layer 34 for the drive rope to pass through. When the sealing part 5 moves inward along the inner protrusion layer 34, the inner protrusion layer 34 clamps the drive rope.

[0052] Specifically, the sealing part 5 is used to open the sleeve 32 and to clamp the drive rope, so as to prevent water from moving inward from the sleeve 32.

[0053] like Figure 7 As shown, the sealing part 5 includes a cylindrical rubber plug 51 with a through hole 53 inside. The section of the rubber plug 51 used for pressing against the inner protruding layer 34 has a slit 52 that divides the rubber plug 51. When the rubber plug 51 is pressed against the inner protruding layer 34, the slit 52 closes and the through hole 53 clamps the drive rope.

[0054] Specifically, the rubber plug 51 has a through hole 53 at its axis and a divided slot 52. The rubber plug 51 can be manually controlled to squeeze the inner protruding layer 34 and to control whether the sleeve 32 passes through. When the rubber plug 51 is squeezed by the inner protruding layer 34, the through hole 53 can squeeze the drive rope to achieve the function of clamping and sealing.

[0055] like Figure 7 The following is a further detail of the sealing part 5. A support ring 54 is fixed to the outward end of the rubber plug 51. The outer arc surface of the support ring 54 fits against the inner wall of the sleeve 32. A control rod 55 extending out of the sleeve 32 is fixed to the outer end face of the support ring 54.

[0056] Specifically, the support ring 54 is used to support the rubber stopper 51, and the movement of the support ring 54 and the rubber stopper 51 can be manually controlled by the control rod 55.

[0057] The inner protruding layer 34 has a circular arc cross-section. When the rubber stopper 51 is pressed against the inner protruding layer 34, the rubber stopper 51 moves from wide to narrow due to the circular arc cross-section of the inner protruding layer 34, and the movement is relatively smooth.

[0058] The slit 52 gradually narrows from the outside to the inside. When the end of the rubber stopper 51 with the slit 52 is pressed against the inner protruding layer 34, the slit 52 is sealed. Specifically, as shown in the figure... Figure 7 As shown, the rubber plug 51 is in a state of being squeezed by the inner protruding layer 34. When the rubber plug 51 is in a relaxed state, the slit 52 gradually narrows from the outside to the inside. When the rubber plug 51 is squeezed, the slit 52 is squeezed, causing the through hole 53 to squeeze the internal drive rope. At the same time, the rubber plug 51 and the inner protruding layer 34 squeeze each other, sealing the sleeve 32.

[0059] Working Principle: Currently, the existing housing 1 contains existing technologies such as a drive rope, a spring, and a ratchet mechanism. When the manual outboard motor starter is activated, pulling the drive rope causes the pawl and clutch assembly to drive the engine crankshaft to rotate at high speed, igniting the engine and starting the outboard motor. However, pulling the drive rope causes wear between the drive rope and the housing 1. Therefore, an improvement is proposed. Through the pulley section 4, the drive rope passes between pulley 44 and pulley 45. Furthermore, because the gap between pulley 44 and pulley 45 deviates from the axis of the sleeve 32, when the drive rope is pulled, it does not move along the axis of the sleeve. The movement is not directly along the axis of the sleeve 32, but will deviate to a certain extent, thus exerting a squeezing effect on pulley 44 or pulley 45. Since pulley 4 can rotate, after pulley 44 or pulley 45 exerts a squeezing effect, pulley 4 will rotate to a stable force state. It should be noted that when the drive rope is pulled to the left front, pulley 45 will rotate to the left front position, and when the drive rope is pulled to the right front, pulley 45 will rotate to the right front position, so that the drive rope is always in a state of squeezing with pulley 45. The rotation of pulley 44 and pulley 45 prevents damage to the drive rope.

[0060] Furthermore, the drive rope passes through the through-hole 53. When one end of the slit 52 of the rubber plug 51 is pressed against the inner protruding layer 34, the slit 52 is closed. The through-hole 53 at one end of the slit 52 of the rubber plug 51 is pressed against the drive rope, keeping the sleeve 32 sealed and minimizing the movement of water from the external environment into the starter. When the control lever 55 is pulled outward, the rubber plug 51 moves outward, opening one end of the slit 52 of the rubber plug 51 and enlarging the through-hole 53, minimizing friction with the drive rope and smoothly starting the outboard motor. It should be noted that both ends of the sleeve 32 have pulleys 4 for supporting the drive rope. Therefore, the drive rope inside the sleeve 32 is suspended, minimizing contact with other components and friction.
