[0040] See also Figure 1 to Figure 2 As shown, according to an embodiment of the present application, an outboard motor angle adjustment device is provided, and the outboard motor angle adjustment device includes: a clamping seat 10, a fixing seat 20 and a first clamping assembly 30. An installation space 11 is provided on the clamping seat 10, and a limiting shaft 15 is passed through the installation space 11. The fixing seat 20 is rotatably provided on the clamping seat 10, and the fixing seat 20 has a first position that rotates to the installation space 11. The first clamping assembly 30 includes a limiting member 31 and a locking portion 32, the limiting member 31 is movably provided on the fixing seat 20, and the locking portion 32 is connected between the limiting member 31 and the fixing seat 20, and the limiting member 31 is movable along a first direction (such as the attached Figure 1 At least two positioning parts 315 are arranged at intervals (in the middle Z direction), and a first limiting groove 313 is arranged on the limiting member 31. The limiting member 31 has a first locking position in which the first limiting groove 313 is clamped on the limiting shaft 15 by an external force to lock the fixing seat 20 in the first position. The limiting member 31 also has a first unlocking position in which the first limiting groove 313 is separated from the limiting shaft 15 by an external force. The locking part 32 cooperates with one of the at least two positioning parts 315 to lock the limiting member 31 in the first locking position or the first unlocking position.

[0041] Specifically, the clamping seat 10 is installed at the tail of the hull, and the outboard motor is installed on the fixing seat 20. When the limiting member 31 is in the first locking position, the outboard motor is locked in the installation space 11 of the clamping seat 10. When the limiting member 31 is in the first locking position, the outboard motor can rotate under the drive of the fixing seat 20.

[0042] Compared with the prior art, when the outboard motor angle adjustment device of this embodiment is unlocked in the beaching mode, it only needs to manipulate the limiter 31 to move the limiter 31 to the first unlocking position. In addition, in the first positioning assembly 30 of the outboard motor angle adjustment device of this embodiment, there is no excessive transmission structure, and the outboard motor angle adjustment device can be unlocked by only separating the first limiter groove 313 from the limiter shaft 15. Compared with the prior art, the outboard motor angle adjustment device of this embodiment has a simpler structure and does not have too many transmission parts, so the outboard motor angle adjustment device will not fail to work due to damage to the transmission parts.

[0043] As attached Figure 6 As shown, the limiting member 31 includes a first section 312 extending along the first direction and a user-operated grip section 311 arranged at one end of the first section 312 away from the limiting axis 15, at least two positioning portions 315 are arranged at intervals on the first section 312, and a first limiting groove 313 is arranged at one end of the first section 312 close to the limiting axis 15.

[0044] Specifically, the user-operated gripping section 311 can be used for the operator to hold. When it is necessary to switch the limiter 31 from the first locked position to the first unlocked position or to switch the limiter 31 from the first unlocked position to the first locked position, an external force along the first direction or an external force along the direction opposite to the first direction can be applied to the user-operated gripping section 311, respectively. In addition, at least two positioning portions 315 are used to cooperate with the locking portion 32 to lock the limiter 31 at different positions. In a specific embodiment, the positioning portions 315 are provided in two, namely, a first positioning groove and a second positioning groove. When the locking portion 32 moves to the first positioning groove, the limiter 31 is in the first unlocked position; when the locking portion 32 moves to the second positioning groove, the limiter 31 is in the second unlocked position.

[0045] Furthermore, the locking portion 32 includes a top screw with a ball. Specifically, the position-limiting member 31 is provided with a plurality of through holes for locking the ball. When the position-limiting member 31 is in the first locking position, the ball is locked in the bottommost through hole along the first direction. The top screw with the ball can provide support for the position-limiting member 31 to prevent the position-limiting member 31 from sliding under the action of gravity.

[0046] In addition, if attached Figure 4 To Attachment Figure 5 As shown, the fixing seat 20 includes a first supporting plate 21, a second supporting plate 22 and a first connecting shaft 23. The first supporting plate 21 and the second supporting plate 22 are spaced apart, and the connecting shaft is connected between the first supporting plate 21 and the second supporting plate 22. The limiting member 31 is connected to the first supporting plate 21 or the second supporting plate 22 through the fixing member 24.

[0047] Specifically, the outboard motor is fixedly connected between the first support plate 21 and the second support plate 22, the limiting member 31 is arranged on the first support plate 21 or the second support plate 22, and the first support plate 21 or the second support plate 22 connected to the limiting member 31 has a connecting hole 25, and the fixing member 24 can be moved along the first direction through the connecting hole 25 to connect with the fixing hole 316 on the limiting member 31 to enhance the structural stability of the first locking assembly 30.

[0048] In order to prevent the first section 312 of the limiting member 31 from rotating freely after the outboard motor angle adjustment device unlocks the beaching mode, in this embodiment, a limiting through hole is provided on the limiting member 31, and the limiting through hole is a long hole 314, and the long hole 314 extends along the first direction. The limiting member 31 is sleeved on the connecting shaft through the limiting through hole to lock the first section 312 of the limiting member 31, that is, the limiting member 31 can only rotate with the rotation of the fixing seat 20.

[0049] Furthermore, the fixing seat 20 also has a second position that is rotated to the outside of the installation space 11, and a second clamping assembly 40 is provided on the fixing seat 20. A limiting portion 50 is provided on the clamping seat 10, and the second clamping assembly 40 has a second locking position in which the clamping assembly is clamped in the limiting portion 50 by an external force, and the second clamping assembly 40 also has a second unlocking position in which the second clamping assembly 40 is separated from the limiting portion 50 by an external force. The second clamping assembly 40 cooperates with the limiting portion 50 to lock the fixing seat 20 in the second position.

[0050] Specifically, when the boat reaches the shore or reaches shallow waters, the outboard motor should be lifted out of the water to avoid collision. In this embodiment, the second position specifically refers to the position of the fixing seat 20 away from the installation space 11 along the first direction, and the second locking assembly 40 cooperates with the limiting portion 50 so that the fixing seat 20 can be locked in the second position.

[0051] Further, the second positioning assembly 40 includes a rotating shaft 41, a rotating arm 42 and a rotating part. The rotating shaft 41 is rotatably arranged on the fixed seat 20. The rotating arm 42 is fixedly connected to the rotating shaft 41, and a limiting section 421 cooperating with the limiting part 50 is arranged on the rotating arm 42. The rotating part includes a stopper 44 and a torsion spring 43, wherein the stopper 44 is arranged on the fixed seat 20, and the torsion spring 43 is sleeved on the rotating shaft 41, and one end of the torsion spring 43 abuts against the rotating shaft 41, and the other end of the torsion spring 43 abuts against the stopper 44.

[0052] Specifically, after unlocking the beach mode, the fixed seat 20 is adjusted to the second position, and the rotating arm 42 is operated to drive the rotating shaft 41 to rotate, and the limit section 421 of the rotating arm 42 is clamped in the limit part 50. The torsion spring 43 is wound by an elastic metal spiral, and both ends of the torsion spring 43 are metal wires. In this embodiment, after the torsion spring 43 is subjected to the external force provided by the rotating shaft 41, a reverse force is applied to the rotating shaft 41, so that after the limit section 421 is clamped in the limit part 50, there is a reverse torque, which improves the clamping effect of the limit section 421 and the limit part 50, and finally fixes the fixed seat 20 in the second position. In a specific embodiment, a control handle 45 is also connected to the rotating arm 42 to facilitate the rotation of the rotating arm 42, and the stopper 44 is the first connecting shaft 23.

[0053] In addition, if attached Figure 7 As shown, the clamping seat 10 is provided with a mounting groove 17 , and the limiting portion 50 includes a limiting block 51 , which is fixedly disposed in the mounting groove 17 , and a second limiting groove 511 adapted to the second locking assembly 40 is provided on the limiting block 51 .

[0054] Specifically, the limiting section 421 of the rotating arm 42 can be inserted into the second limiting groove 511. Since the external force applied by the rotating arm 42 to the limiting block 51 is relatively large, the limiting block 51 is easily worn and damaged after long-term use. Therefore, in this embodiment, the limiting block 51 is separately provided with the clamping seat 10, and the limiting block 51 can be replaced after it is damaged.

[0055] Furthermore, the stopper 51 includes at least one of the three types of stoppers, namely, a stainless steel stopper, a titanium alloy stopper, and a tungsten alloy stopper. In the present embodiment, the stopper 51 is a stainless steel stopper. On the one hand, the stainless steel stopper has high strength, and on the other hand, the cost of the stainless steel stopper is lower than that of the titanium alloy stopper and the tungsten alloy stopper. Of course, in some embodiments, the stopper 51 may also be a titanium alloy stopper or a tungsten alloy stopper with higher strength.

[0056] Optionally, the clamping seat 10 includes an aluminum alloy clamping seat. In order to reduce the overall weight of the clamping seat 10 in this embodiment, the clamping seat 10 is selected from an aluminum alloy clamping seat.

[0057] Furthermore, a plurality of mounting holes 14 are provided on two opposite side walls of the mounting space 11, and the plurality of mounting holes 14 are arranged along the second direction (such as the attached Figure 1 The mounting holes 14 on the two opposite side walls are arranged one by one, and the limiting shafts 15 can be selectively installed in the two corresponding mounting holes 14.

[0058] In a specific embodiment, as shown in the attached Figure 2As shown, the clamping seat includes a first clamping plate 12, a second clamping plate 13 and a second connecting shaft 16. The first clamping plate 12 and the second clamping plate 13 are arranged at intervals. The second connecting shaft 16 is connected between the first clamping plate 12 and the second clamping plate 13. The first clamping plate 12, the second clamping plate 13 and the second connecting shaft 16 are arranged to form an installation space 11. The first clamping plate 12 and the second clamping plate 13 are two opposite side walls of the installation space 11. A plurality of mounting holes 14 are arranged at positions corresponding to the first clamping plate 12 and the second clamping plate 13. The limiting shaft 15 can be selectively installed in two corresponding mounting holes 14 of the first clamping plate 12 and the second clamping plate 13 to adjust the angle at which the fixing seat 20 is fixed on the limiting shaft 15.

[0059] In addition, the limit blocks 51 include two, which are respectively arranged on the first clamping plate 12 and the second clamping plate 13. The second connecting shafts 16 include at least two, at least one second connecting shaft 16 is connected to the first clamping plate 12 and the second clamping plate 13 near the plurality of mounting holes 14, and at least one second connecting shaft 16 is connected to the first clamping plate 12 and the second clamping plate 13 near the limit blocks 51.

[0060] In summary, the outboard motor angle adjustment device of the present application has a simple structure and is easy to operate when unlocking the beaching mode. Secondly, the limiter 50 of the present application is separately arranged from the clamping seat 10, and the material of the limiter 50 can be flexibly selected to provide the structural strength of the limiter 50.

[0061] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0062] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0063] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
