Description

Technical Field

[0001] This utility model relates to the field of marine equipment, and in particular to an adjustable clamping gear device and an outboard motor. Background Technology

[0002] Outboard motor clamps are located at the junction of the motor and the hull, serving to connect and secure the two. Since boats inevitably face requirements such as docking and beaching during operation, and the angle of the outboard motor varies depending on the water conditions, the design of outboard motor clamps often needs to accommodate adjustments to different tilting angles. Traditional outboard motor clamps often suffer from cumbersome unlocking and time-consuming operation, making them unfriendly to users, prone to failure, and unreliable. Utility Model Content

[0003] This utility model provides a clamping gear adjustable device and an outboard motor, which is easy to operate and highly reliable.

[0004] On the one hand, this utility model provides a clamping gear adjustable device for outboard motors, comprising:

[0005] A clamp for connecting to the hull, the clamp having multiple stop holes;

[0006] A mounting base is used to mount the machine body, and the mounting base is rotatably connected to the clamp via a main shaft; a plurality of the stop holes are arranged along the rotation direction of the mounting base;

[0007] A limiting pin, detachably inserted into the stop hole, abuts against the fixed seat to restrict downward rotation of the fixed seat; and,

[0008] The gear adjustment mechanism includes a slider, a connecting rod, and an adjustment handle. The slider is slidably disposed on the fixed base. The connecting rod connects the adjustment handle and the slider. The adjustment handle is rotatably engaged with the clamp and the fixed base via the main shaft, and drives the slider to move closer to or away from the main shaft via the connecting rod.

[0009] Specifically, when the slider slides to a position relatively close to the main shaft, the slider and the limiting pin are misaligned in the rotation direction of the fixed seat, and the adjusting handle can drive the fixed seat to rotate relative to the clamp; when the slider is located relatively far from the main shaft and the fixed seat abuts against the limiting pin, the limiting pin is clamped between the fixed seat and the slider in the rotation direction of the fixed seat, so as to fix the relative position of the fixed seat and the clamp.

[0010] The fixed base is provided with a sliding groove, and the slider is slidably disposed in the sliding groove. A limiting groove wall is provided at one end of the sliding groove near the main shaft. When the slider slides to a position close to the main shaft, the slider abuts against the limiting groove wall.

[0011] One end of the connecting rod is rotatably connected to the adjusting handle, and the axis of rotation of the connecting rod connecting the adjusting handle is parallel to the axis of the main shaft.

[0012] The clamp includes two opposing side panels, and the gear position hole is disposed on the side panel; the fixed base and the gear position adjustment mechanism are located between the two side panels.

[0013] An elastic element is provided between the adjusting handle and the fixed base. The elastic element provides elastic force to rotate the adjusting handle relative to the fixed base, so that the slider moves away from the main shaft.

[0014] The fixture includes a side panel, and the side panel facing the fixed base has a recessed stop groove. The stop groove has a positioning groove wall, which is oriented towards the main shaft. The positioning groove wall has multiple stop slots. The multiple stop slots are arranged along the rotation direction of the fixed base and are all located above the multiple stop holes.

[0015] A positioning pin is provided on the side of the slider facing the side panel. The positioning pin extends into the gear slot and can move in and out of the gear slot under the action of the slider.

[0016] The gear slot has an upward guide slot and a downward guide slot. Both the upward guide slot and the downward guide slot are arc-shaped and are arranged along the rotation direction of the fixed seat. They are both facing the fixed seat. The downward guide slot is closer to the main shaft than the upward guide slot, and a separation strip is provided between them.

[0017] The positioning pin is slidably disposed on the slider along the axial direction of the main shaft. A compression spring is provided between the positioning pin and the slider. The compression spring is used to provide elastic force so that the positioning pin slides toward the side panel and so that the positioning pin can abut against the bottom of the upper guide groove or the bottom of the lower guide groove.

[0018] Among them, the multiple gear slots include a low gear slot, a high gear slot and an ultra-high gear slot arranged from bottom to top;

[0019] The top of the upward guide groove extends to the high-grade slot opening, and an upward step is provided at a position corresponding to the high-grade slot opening. The upward step can abut against the bottom of the positioning pin so that the positioning pin enters the high-grade slot opening and restricts the downward movement of the positioning pin.

[0020] The surfaces of the high-grade slot and the ultra-high-grade slot facing the fixed base are both in contact with the downward guide groove, so that the positioning pin can move between the high-grade slot, the ultra-high-grade slot and the downward guide groove.

[0021] The isolation strip extends from the upper step to the lower gear slot, and the upper guide groove and the lower guide groove smoothly transition at positions corresponding to the multiple gear holes.

[0022] The high-end slot includes a first high-end slot and a second high-end slot. The second high-end slot is higher than the first high-end slot. The positioning pin is positioned in the second high-end slot. The fixed seat drives the fuselage to rotate to a roughly horizontal position, so that the fuselage can rotate around the vertical axis into the hull.

[0023] On the other hand, the present invention also provides an outboard motor, including a body and the aforementioned adjustable clamp position device; the body is disposed on the fixed seat of the adjustable clamp position device.

[0024] The adjustable clamping device and outboard motor provided by this utility model have multiple positioning holes arranged along the rotation direction of the fixed seat. When the limiting pin is inserted into different positioning holes, the fixed seat and the limiting pin abut against each other, which can limit the downward rotation of the fixed seat, so that the fixed seat and the machine body can be located at different lifting angles when they rotate to the lowest position. When the slider slides to a position away from the main shaft, the slider and the fixed seat clamp the limiting pin, so that the fixed seat and the machine body are fixed in position with the clamp, thereby locking the machine body at the lifting angle. By rotating the adjustment handle, the connecting rod drives the slider to slide. The slider and the limiting pin are misaligned, which can release the position lock of the fixed seat, and the fixed seat and the machine body can rotate upward to change the lifting angle. Using the adjustment handle to drive the slider to slide, the fixed seat and the machine body can be quickly fixed and unlocked, which is convenient to operate. The limiting pin can effectively prevent the fixed seat and the machine body from rotating downward out of position, ensuring the reliability of the limit. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] In the diagram, units with similar structures are represented by the same labels.

[0033] Please refer to Figure 1 This utility model discloses an outboard motor, including a motor body 900 and a clamp position adjustable device 100; the motor body 900 is connected to the hull through the clamp position adjustable device 100, and the lifting angle of the motor body 900 can be adjusted by using the clamp position adjustable device 100.

[0034] like Figure 2 As shown, the adjustable clamp position device 100 includes a clamp 1, a fixed base 2, a limiting pin 3, and a position adjustment mechanism 4. The clamp 1 is used to connect to the hull, and the fixed base 2 is used to mount the fuselage 900, which is mounted on the fixed base 2. The fixed base 2 is rotatably connected to the clamp 1 via a main shaft 5. The limiting pin 3 cooperates with the position adjustment mechanism 4 to adjust the rotation angle of the fixed base 2 relative to the clamp 1, thereby adjusting the tilting angle of the fuselage 900.

[0035] In this embodiment, the outboard motor is an electric outboard motor, that is, the hull 900 is equipped with a motor and a propeller, the motor drives the propeller to rotate to output propulsion power.

[0036] The clamp 1 is provided with multiple stop holes 10, which are arranged along the rotation direction of the fixed base 2. The limiting pin 3 is detachably inserted into the stop hole 10 to abut against the fixed base 2 and restrict the downward rotation of the fixed base 2. When the limiting pin 3 is inserted into different stop holes 10, the fixed base 2 will abut against the limiting pin 3 when it rotates downward, which can restrict the fixed base 2 from continuing to rotate downward, so that the fixed base 2 and the machine body 900 can be located at different tilting angles when they rotate to the lowest position.

[0037] like Figure 3 As shown, the gear adjustment mechanism 4 includes a slider 41, a connecting rod 42, and an adjustment handle 43. The slider 41 is slidably mounted on the fixed base 2, and the connecting rod 42 connects the adjustment handle 43 and the slider 41. The adjustment handle 43 is rotatably engaged with both the clamp 1 and the fixed base 2 via the main shaft 5, and drives the slider 41 to move closer to or away from the main shaft 5 via the connecting rod 42.

[0038] When the slider 41 slides to a position relatively close to the main shaft 5, the slider 41 and the limit pin 3 are misaligned in the rotation direction of the fixed seat 2, so that the limit pin 3 will not hinder the slider 41 from rotating with the fixed seat 2. The adjusting handle 43 can drive the fixed seat 2 to rotate relative to the clamp 1. The user can operate the adjusting handle 43 to rotate relative to the clamp 1, thereby driving the fixed seat 2 to rotate and adjusting the lifting angle of the machine body 900.

[0039] When the slider 41 is located relatively far from the main shaft 5 and the fixed seat 2 abuts against the limiting pin 3, the limiting pin 3 clamps between the fixed seat 2 and the slider 41 in the rotation direction of the fixed seat 2, thereby fixing the relative position of the fixed seat 2 and the clamp 1, and locking the machine body 900 at the tilting angle. The limiting pin 3 can effectively prevent the fixed seat 2 and the machine body 900 from rotating downwards out of bounds, ensuring the reliability of the limiting.

[0040] When it is necessary to change the tilting angle of the body 900, the user can turn the adjusting handle 43 upwards. By turning the adjusting handle 43, the slider 41 moves, causing it to slide and become misaligned with the limiting pin 3, thus releasing the position lock of the fixed base 2 and the body 900. Further turning the adjusting handle 43 upwards allows the fixed base 2 and the body 900 to rotate upwards, thereby changing the tilting angle. Using the adjusting handle 43 to move the slider 41 allows for quick fixing and unlocking of the fixed base 2 and the body 900, making operation convenient.

[0041] like Figure 3As shown, the fixed base 2 is provided with a slide groove 21, and the slider 41 is slidably disposed in the slide groove 21. The slide groove 21 can ensure the stability and reliability of the slider 41 sliding, and make the structure compact, reducing the space occupied by the slider 41. A limit groove wall 211 is provided at one end of the slide groove 21 near the main shaft 5. When the slider 41 slides to the position near the main shaft 5, the slider 41 abuts against the limit groove wall 211. At this time, if the adjusting handle 43 is turned upward, the slider 41 acts on the limit groove wall 211, which can drive the fixed base 2 to rotate, so that the adjusting handle 43 can drive the fixed base 2 and the machine body 900 to rotate upward together, making it convenient to adjust the tilting angle of the machine body 900 by adjusting the adjusting handle 43. In another embodiment, a slide rail can be provided on the fixed base, and the sliding stability of the slider can be ensured by the sliding cooperation between the slider and the slide rail. At the same time, a limiting block is provided at one end of the slide rail near the main shaft, or a limiting block is provided on the fixed base. When the slider slides to a position near the main shaft, the slider or the adjusting handle abuts against the limiting block, thereby causing the adjusting handle to drive the fixed base to rotate upward.

[0042] One end of the connecting rod 42 is rotatably connected to the adjusting handle 43, and the axis of rotation of the connecting rod 42 connecting the adjusting handle 43 is parallel to the axis of the main shaft 5. When the adjusting handle 43 rotates upward about the axis of the main shaft 5, the connecting rod 42 rotates relative to the adjusting handle 43, so that the other end of the connecting rod 42 can drive the slider 41 to slide.

[0043] In this embodiment, the other end of the connecting rod 42 is fixedly connected to the slider 41. A strip-shaped hole can be provided on the adjusting handle 43, extending along the length direction of the adjusting handle 43. The rotation shaft of the adjusting handle 43 connected to the connecting rod 42 is movably disposed in the adjusting hole. The connecting rod 42 can rotate relative to the adjusting handle 43, and can also slide relative to the adjusting handle 43 along the length direction of the adjusting handle 43, so as to ensure the smooth linkage of the adjusting handle 43, the connecting rod 42, and the slider 41. In other embodiments, the other end of the connecting rod 42 can also be slidably connected to the slider 41, and the connecting rod 42 and the adjusting handle 43 are only rotatably connected, so that the adjusting handle 43, the connecting rod 42, and the slider 41 are connected to form a crank-slider 41 mechanism, thereby ensuring the reliability of the gear adjustment mechanism 4.

[0044] like Figure 2 As shown, during use, the clamp 1 is fixed to the hull by two parallel push rods 11 set on the hull clamp 1. The external thread of the push rod 11 is engaged with the internal thread of the clamp 1. The thread design achieves the effect of locking between the clamp 1 and the hull.

[0045] Combination Figure 2 and Figure 4As shown, a locking pin 31 is provided on the limiting pin 3. One end of the limiting pin 3 is bent towards the locking pin 31 to form a handle 32. The handle 32 and the locking pin 31 are located on opposite sides of the side panel 12, and the locking pin 31 and the fixing seat 2 are located on the same side of the side panel 12. The wall of the gear position hole 10 is provided with a clearance notch 101 for the locking pin 31 to pass through. The side panel 12 can shield the adjustment mechanism, preventing the operation of the adjustment mechanism from being interfered with by external factors. The handle 32 can be easily pulled out of the limiting pin 3; the handle 32 and the locking pin 31 are located on opposite sides of the side panel 12 to prevent the limiting pin 3 from slipping out of the gear position hole 10. The handle 32 and the locking pin 31 are located at the same position in the circumferential direction of the limiting pin 3. The limiting pin 3 can be pulled out only after the handle 32 is aligned with the clearance notch 101, which is convenient for operation.

[0046] Combination Figure 2 and Figure 5 As shown, the clamp 1 includes two opposing side panels 12, with gear shift holes 10 disposed on the side panels 12. The fixed base 2 and the gear shift adjustment mechanism 4 are located between the two side panels 12. The two ends of the limiting pin 3 can respectively pass through the gear shift holes 10 of the two side panels 12, ensuring the reliability of the connection between the limiting pin 3 and the clamp 1. Furthermore, the middle part of the limiting pin 3 can be used to abut against the fixed base 2, improving structural strength and ensuring reliable limiting. The two side panels 12 can protect the gear shift adjustment mechanism 4, preventing its movement from being disturbed by external factors and ensuring operational reliability.

[0047] like Figure 3 As shown, an elastic element 44 is provided between the adjusting handle 43 and the fixed base 2. The elastic element 44 provides elastic force to make the adjusting handle 43 rotate relatively fixedly, so that the slider 41 moves away from the main shaft 5. When the user rotates the adjusting handle 43 upward and releases it, without any other external force, the elastic element 44 can provide a downward rotational restoring force to the adjusting handle 43, so that the adjusting handle 43 drives the slider 41 to return to a position relatively away from the main shaft 5. Here, in other embodiments, the weight of the adjusting handle 43 and the slider 41 itself can also be used to make the slider 41 move away from the main shaft 5.

[0048] In this embodiment, the elastic element 44 is a tension spring, located below the adjusting handle 43, with its two ends connected between the adjusting handle 43 and the fixed base 2, respectively. When the adjusting handle 43 is rotated upward, the elastic element 44 is stretched and deformed, thereby providing a downward elastic force to the adjusting handle 43. Here, in this embodiment, the elastic element 44 can also be a compression spring, located above the adjusting handle 43, or the elastic element 44 can be an elastic component of other structural forms.

[0049] Combination Figure 5 and Figure 6As shown, the side panel 12 facing the fixed base 2 has a recessed gear groove 120. The gear groove 120 has a positioning groove wall 121, which faces the main shaft 5. The positioning groove wall 121 has multiple gear slots, which are arranged along the rotation direction of the fixed base 2 and are all located above the multiple gear holes 10. In this embodiment, the multiple gear slots, depending on their position, include a low gear slot 1211, a high gear slot 1212, and an ultra-high gear slot 1213 arranged sequentially from bottom to top.

[0050] A positioning pin 45 is provided on the side of the slider 41 facing the side panel 12. The positioning pin 45 extends into the gear slot 120 and can move in and out of each gear slot under the action of the slider 41.

[0051] In this embodiment, by using the cooperation of the limiting pin 3 and multiple gear holes 10, the fixed base 2 and the machine body 900 can be limited to multiple positions at a lower tilting angle; by using the cooperation of the positioning pin 45 and multiple gear slots, the fixed base 2 and the machine body 900 can be limited to multiple positions at a higher tilting angle, thereby facilitating the adjustment of the tilting angle of the machine body 900.

[0052] In this embodiment, both side panels 12 are provided with a gear slot 120. Correspondingly, there can also be two positioning pins 45, which cooperate with the gear slots 120 of the two side panels 12.

[0053] like Figure 6 As shown, the gear slot 120 has an upward guide slot 122 and a downward guide slot 123. Both the upward guide slot 122 and the downward guide slot 123 are arc-shaped and are arranged along the rotation direction of the fixed seat 2, and both are arranged towards the fixed seat 2. The downward guide slot 123 is closer to the main shaft 5 than the upward guide slot 122, and a separation strip 124 is provided between the two.

[0054] like Figure 5 As shown, the positioning pin 45 is slidably disposed on the slider 41 along the axial direction of the main shaft 5. A compression spring 46 is disposed between the positioning pin 45 and the slider 41. The compression spring 46 is used to provide elastic force so that the positioning pin 45 slides toward the side panel 12 and so that the positioning pin 45 can abut against the bottom of the upper guide groove 122 or the bottom of the lower guide groove 123.

[0055] The upward guide groove 122 forms a path for the positioning pin 45 to move upward with the fixed base 2 and the machine body 900, while the downward guide groove 123 forms a path for the positioning pin 45 to move downward with the fixed base 2 and the machine body 900. An isolation strip 124 separates the upward guide groove 122 and the downward guide groove 123. Utilizing the elastic abutment between the positioning pin 45 and the upward and downward guide grooves 122 and 123, the upward and downward movement of the positioning pin 45 follows a predetermined path, facilitating control of the tilting and lowering of the machine body 900. When the machine body 900 needs to be lowered, the user needs to operate the adjustment handle 43 to slide the slider 41 upward. After reaching its limit position, the fixed base 2 rotates relative to the clamp 1, and simultaneously, the fixed base 2 drives the positioning pin 45 into the downward guide groove 123, allowing the machine body 900 to fall smoothly and ensuring safety.

[0056] like Figure 6 As shown, the multiple gear slots include a low gear slot 1211, a high gear slot 1212, and a very high gear slot 1213 arranged sequentially from bottom to top. The top of the upward guide groove 122 extends to the high gear slot 1212, and an upward step 1222 is provided at a corresponding position in the high gear slot 1212. The upward step 1222 can abut against the bottom of the positioning pin 45, so that the positioning pin 45 enters the high gear slot 1212 and restricts the downward movement of the positioning pin 45.

[0057] When the user adjusts the tilting angle of the body 900, causing the mounting base 2 and the body 900 to rotate upwards, the positioning pin 45 can move upwards along the upward guide groove 122 under the action of the slider 41. When the positioning pin 45 moves to the high-position slot 1212, the positioning pin 45 moves towards the side panel 12 under the action of the compression spring 46, and then moves to the position above the upward step 1222. The upward step 1222 allows the positioning pin 45 to move into the high-position slot 1212. Even if the user releases the adjustment handle 43 and the body 900 tries to move downwards under the action of gravity, the upward step 1222 can prevent the positioning pin 45 from moving downwards, thus preventing the body 900 from moving downwards under the action of gravity.

[0058] When the positioning pin is in the low position slot 1211, the fixed seat can lift the body freely and has a minimum point limit to prevent the propeller from entering the water too deeply. This makes it suitable for propelling boats in shallow water or areas with reefs, and prevents the propeller from hitting objects on the bottom of the water and causing damage.

[0059] When the positioning pin is limited to the high-position slot 1212, the fixed seat causes the fuselage to tilt to a relatively small angle relative to the horizontal plane, so that the propeller enters the water at a shallow depth. The distance between the propeller and the water surface can be less than the distance between the bottom of the hull and the water surface, so that the propeller can output propulsion power in shallow waters, propelling the boat to run on the beach and avoiding damage to the propeller from objects at the bottom of the beach.

[0060] When the positioning pin is limited to the highest position slot 1213, the fixed seat drives the body to tilt up to a position roughly level with the horizontal plane, the propeller leaves the water surface, and the propeller no longer outputs propulsion power. This is suitable for the propeller to stop outputting propulsion power and to avoid the propeller being immersed in water for a long time, thus preventing the propeller from being corroded by prolonged exposure to water.

[0061] The surfaces of the high-gear slot 1212 and the ultra-high-gear slot 1213 facing the fixed base 2 are in contact with the downward guide groove 123, so that the positioning pin 45 can move between the high-gear slot 1212, the ultra-high-gear slot 1213 and the downward guide groove 123. The isolation strip 124 extends from the upper step 1222 to the low-gear slot 1211, and the upper guide groove 122 and the downward guide groove 123 smoothly transition at positions corresponding to the multiple gear holes 10.

[0062] The upward step 1222 during the upward process can restrict the positioning pin 45 to a position above the high-level slot 1212, so that the body 900 will not fall. For example, when the positioning pin 45 is in the downward guide groove 123 and located between the high-end slot 1212 and the ultra-high-end slot 1213, if the user releases the adjustment handle 43, under the action of the elastic element 44, the positioning pin 45 moves away from the main shaft 5 along with the slider 41. At the same time, the machine body 900 will move downward under its own gravity. When the positioning pin 45 moves to the high-end slot 1212, the positioning pin 45 moves to the high-end slot 1212 along with the slider 41 under the action of the elastic element 44. Since the high-end slot 1212 is provided with an upward step 1222, the positioning pin 45 will be located on the upward step 1222. The upward step 1222 limits the positioning pin 45, preventing the positioning pin 45 from moving downward, thereby preventing the fixed base 2 and the machine body 900 from moving downward, so as to avoid the machine body 900 falling directly to the lowest position and ensuring safety during use.

[0063] When it is necessary to lower the body's 900-degree tilting angle, the user must hold the adjustment handle 43. The adjustment handle 43 drives the slider 41 so that the positioning pin 45 is located at the downward guide groove 123 and does not enter the high-level groove 1212. Only then can the body's 900-degree tilting angle be lowered normally, so as to ensure that the tilting angle is lowered under human control, thereby ensuring safety.

[0064] In this embodiment, there is one extremely high-gear slot 1213. Alternatively, there can be two or more extremely high-gear slots, including a first extremely high-gear slot and a second extremely high-gear slot. The second extremely high-gear slot is higher than the first extremely high-gear slot. The positioning pin is positioned in the second extremely high-gear slot. The fixed base drives the fuselage to rotate to a roughly horizontal position, allowing the fuselage to rotate around a vertical axis into the hull. The vertical axis can be located between the fuselage and the fixed base, and is approximately vertically positioned when the fuselage rotates with the fixed base to a near-horizontal position. The fuselage can rotate around the vertical axis into the hull, and can be folded back into the hull when not in use.

[0065] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
