如前文描述,档位卡架10的一端连接在船用推进器机身110上,在外力(如操作者施加的力)带动船用推进器机身110相对固定座30转动时,船用推进器机身110将带动档位卡架10活动,基于第一档位槽C1和第二档位槽C2的形状设计,可使档位卡架10的轴件13的活动轨迹为前述的滑移轨迹S1。所述滑移轨迹S1经过所述第一卡位W1和所述第二卡位W2,即轴件13可以移动至配合于第一卡位W1或第二卡位W2,以使档位卡架10将船用推进器机身110支撑于水上状态或水下状态。如图中所示,可选地,在第一卡位W1或第二卡位W2处,第一档位槽C1的槽侧面P3处设置下凹形成的凹口。参见图7、图8和图12,轴件13 在卡入凹口时,船用推进器机身110的重力将档位卡架10及其上的轴件13压抵于凹口的底部,使得轴件13能够较稳定地限位于第一卡位W1或第二卡位W2,需要变动轴件13位置时,需要先使用足够大的外力(如操作者向上提拉船用推进器机身110)克服重力来使轴件13向上退出凹口。加之,所述轴件13沿轴向弹性地抵顶于第一档位槽C1的槽底面P5,即轴件13的端面和第一档位槽C1的槽底面P5之间的摩擦阻力也能够一定程度阻止限位于第一卡位W1或第二卡位W2的轴件13发生意外的位置变化。此外,本实施例中的滑移轨迹S1不在同一平面上,第一档位槽C1的槽底面P5在滑移轨迹S1上具有不同的凹入深度,例如设置第一档位槽C1的槽底面P5在从第二卡位W2过渡到第一卡位W1的过程中存在高差变化,如此,轴件13在不同卡位之间的变动除了需要克服重力和前述摩擦阻力提供的阻尼外,还需要克服轴件13受到的来自弹性件12的弹性力,以迫使轴件13在以滑移轨迹S1移动的过程中克服弹性力,进一步提高船用推进器100在外界干扰而发生意外的状态变动的难度,提高本实施例的船用推进器100在不同卡位的稳定性,提高使用安全性。As described above, one end of the gear bracket 10 is connected to the marine propeller body 110. When an external force (such as the force exerted by the operator) drives the marine propeller body 110 to rotate relative to the fixed base 30, the marine propeller body 110 will drive the gear bracket 10 to move. Based on the shape design of the first gear slot C1 and the second gear slot C2, the movement trajectory of the shaft 13 of the gear clamp 10 can be the aforementioned sliding trajectory S1. The sliding track S1 passes through the first clamping position W1 and the second clamping position W2, that is, the shaft member 13 can move to fit the first clamping position W1 or the second clamping position W2, so that the gear rack 10. Support the marine propeller body 110 in an above-water state or an underwater state. As shown in the figure, optionally, at the first locking position W1 or the second locking position W2, a concave notch is provided at the groove side P3 of the first gear groove C1. Referring to Figures 7, 8 and 12, when the shaft 13 is stuck into the notch, the gravity of the marine propeller body 110 presses the gear bracket 10 and the shaft 13 thereon against the bottom of the notch, so that The shaft 13 can be relatively stably limited to the first locking position W1 or the second locking position W2. When the position of the shaft 13 needs to be changed, a sufficient external force needs to be used first (such as the operator pulling up the marine propeller body 110). The shaft 13 exits the notch upwards against gravity. In addition, the shaft member 13 elastically resists the groove bottom surface P5 of the first gear groove C1 along the axial direction, that is, the friction resistance between the end surface of the shaft member 13 and the groove bottom surface P5 of the first gear groove C1 can also be reduced. This prevents the shaft member 13 limited at the first locking position W1 or the second locking position W2 from unexpected position changes to a certain extent. In addition, the sliding track S1 in this embodiment is not on the same plane. The groove bottom surface P5 of the first gear groove C1 has different concave depths on the sliding track S1. For example, the groove bottom surface of the first gear groove C1 is provided. There is a height difference change in P5 during the transition from the second clamping position W2 to the first clamping position W1. In this way, the movement of the shaft 13 between different clamping positions not only needs to overcome the damping provided by gravity and the aforementioned frictional resistance, but also needs to overcome the damping provided by gravity and the aforementioned frictional resistance. It is necessary to overcome the elastic force from the elastic member 12 received by the shaft member 13, so as to force the shaft member 13 to overcome the elastic force during the movement in the sliding trajectory S1, and further improve the probability of unexpected state changes of the marine propeller 100 due to external interference. difficulty, improve the stability of the marine propeller 100 of this embodiment in different clamping positions, and improve the safety of use.
继续参见图12,在一种示例性实施方式中,第一档位槽C1的槽底面P5包括相连的第一面段P11和第二面段P12,所述滑移轨迹S1经过所述第一面段P11和所述第二面段P12。所述第一卡位W1位于所述第一面段P11处,所述第二卡位W2位于所述第二面段P12远离所述第一面段P11一端,所述第一面段P11的凹入深度大于所述第二面段P12的凹入深度。配合参见图13和图14,所述第一面段P11和所述第二面段P12之间通过第一过渡面段P21过渡连接,所述第一过渡面段P21和所述第二面段P12倾斜相交,如,第一过渡面段P21和第二面段P12相交的夹角呈60-90°。如此,在轴件13从第二卡位W2沿第二面段P12过渡到第一面段P11的第一卡位W1时,轴件13可在弹性件12的作用下沿轴向移动至撞击第一面段P11处,发出容易被感知的振动或撞击声。尤其当第一过渡面段P21和第二面段P12的夹角达到或接近90°(第一过渡面段P21和第二面段P12垂直)时,轴件13从第二面段P12到第一面段P11的过程中,轴件13的轴向位置将发生突变,得轴件13在弹性件12的带动下,撞击第一面段P11产生撞击声,操作者在感知到该声音信号后即可停止施力,由船用推进器机身110自重带动轴件13下行卡入第一卡位W1。Continuing to refer to Figure 12, in an exemplary embodiment, the groove bottom surface P5 of the first gear groove C1 includes a connected first surface segment P11 and a second surface segment P12, and the sliding trajectory S1 passes through the first surface segment P11 and the second surface segment P12. Noodle segment P11 and said second noodle segment P12. The first clamping position W1 is located at the first surface segment P11, and the second clamping position W2 is located at an end of the second surface segment P12 away from the first surface segment P11. The recessed depth is greater than the recessed depth of the second surface segment P12. Referring to Figures 13 and 14, the first transition surface segment P11 and the second surface segment P12 are transitionally connected through a first transition surface segment P21, and the first transition surface segment P21 and the second surface segment P12 intersects obliquely, for example, the first transition surface segment P21 and the second surface segment P12 intersect at an angle of 60-90°. In this way, when the shaft member 13 transitions from the second clamping position W2 along the second surface segment P12 to the first clamping position W1 of the first surface segment P11, the shaft member 13 can move axially to the impact point under the action of the elastic member 12. At the first surface segment P11, an easily perceptible vibration or impact sound is emitted. Especially when the angle between the first transition surface segment P21 and the second surface segment P12 reaches or approaches 90° (the first transition surface segment P21 and the second surface segment P12 are perpendicular), the shaft member 13 moves from the second surface segment P12 to the second surface segment P12. During the process of moving one surface segment P11, the axial position of the shaft member 13 will undergo a sudden change, so that the shaft member 13, driven by the elastic member 12, will hit the first surface segment P11 to generate an impact sound. After the operator senses the sound signal Then the force application is stopped, and the weight of the marine propeller body 110 drives the shaft 13 downward to snap into the first locking position W1.
一种实施方式中,所述第一档位槽C1的槽底面P5凸设有分隔壁31a。所述分隔壁31a的上下两端分别和所述第一档位槽C1的槽侧面P3的上下两端相间隔,所述滑移轨迹S1围绕所述分隔壁31a设置。所述第一档位槽C1的槽底面P5还包括第三面段P13,所述第三面段P13的上端通过第二过渡面段P22过渡连接于所述第一面段P11的位置较高一端,所述第三面段P13的下端通过第三过渡面段P23过渡连接于所述第二面段P12的位置较低一端。In one embodiment, a partition wall 31a is protruding from the groove bottom surface P5 of the first gear groove C1. The upper and lower ends of the partition wall 31a are respectively spaced apart from the upper and lower ends of the groove side P3 of the first gear groove C1, and the sliding track S1 is arranged around the partition wall 31a. The groove bottom surface P5 of the first gear groove C1 also includes a third surface segment P13. The upper end of the third surface segment P13 is transitionally connected to the first surface segment P11 through a second transition surface segment P22 at a higher position. On one end, the lower end of the third surface segment P13 is transitionally connected to the lower end of the second surface segment P12 through the third transition surface segment P23.
在一些实施方式中,第二面段P12和第三面段P13分别位于分隔壁31a的水平方向X两侧,分隔壁31a限定所述第二面段P12的远离所述第一面段P11一侧的边界,并具有朝向所述第二面段P12一侧的引导面P7,所述引导面P7为较高一端向所述第一面段P11一侧倾斜的斜面或弧形面。所述第一面段P11位于所述第二面段P12在水平方向X远离分隔壁31a的一侧,且所述第一面段P11以其位置较高一端连接于所述第二面段P12的较高一端,所述第一卡位W1位于所述第一面段P11的位置较低一端之处。参见图12,前述的所述滑移轨迹S1包括第一轨迹S11和第二轨迹S12。其中,所述第一轨迹S11为从所述第二卡位W2经所述第二面段P12较高一端、所述第一面段P11较高一端、所述第一面段P11较低一端到达第一卡位W1的路径;第一轨迹S11上,轴件13移动平顺,且在沿第一面段P11下落至第一卡位 W1的轴件13不易受外界干扰力而意外脱出第一面段P11,增大了轴件13从第一卡位W1进入第三面段P13的水平路径,降低轴件13意外脱出第一卡位W1的可能,提高使用安全性。In some embodiments, the second surface segment P12 and the third surface segment P13 are respectively located on both sides of the partition wall 31a in the horizontal direction X, and the partition wall 31a defines a distance of the second surface segment P12 away from the first surface segment P11. side boundary, and has a guide surface P7 toward the side of the second surface segment P12. The guide surface P7 is an inclined surface or an arc-shaped surface with a higher end inclined toward the side of the first surface segment P11. The first surface segment P11 is located on the side of the second surface segment P12 away from the partition wall 31a in the horizontal direction X, and the higher end of the first surface segment P11 is connected to the second surface segment P12 The first locking position W1 is located at the lower end of the first surface segment P11. Referring to Fig. 12, the aforementioned slip trajectory S1 includes a first trajectory S11 and a second trajectory S12. The first trajectory S11 is from the second clamping position W2 through the higher end of the second surface segment P12, the higher end of the first surface segment P11, and the lower end of the first surface segment P11. The path to reach the first locking position W1; on the first trajectory S11, the shaft 13 moves smoothly, and the shaft 13 that drops to the first locking position W1 along the first surface section P11 is not susceptible to external interference and accidentally escapes from the first locking position W1. The surface segment P11 increases the horizontal path for the shaft member 13 to enter the third surface segment P13 from the first clamping position W1, thereby reducing the possibility of the shaft member 13 accidentally escaping from the first clamping position W1 and improving the safety of use.
前述引导面P7的存在,使得轴件13在沿第二面段P12移动时,能够被引导面P7引导而以较确定的路径移动,并产生一定的远离第三面段P13一侧的水平位移。The existence of the aforementioned guide surface P7 enables the shaft member 13 to be guided by the guide surface P7 to move in a more certain path when moving along the second surface segment P12, and generate a certain horizontal displacement away from the third surface segment P13. .
所述第一档位槽C1的槽侧面P3具有第一支撑面P8(即前述对应第一卡位W1处的凹口的底面),所述第一支撑面P8连接于所述第一面段P11的较低一端,用于支撑位于所述第一卡位W1时的所述轴件13的周面。第一支撑面P8的形状可以为半圆弧形,以适配圆柱状的轴件13。The groove side P3 of the first gear groove C1 has a first supporting surface P8 (that is, the bottom surface corresponding to the notch at the first clamping position W1), and the first supporting surface P8 is connected to the first surface segment The lower end of P11 is used to support the peripheral surface of the shaft member 13 when it is in the first locking position W1. The shape of the first supporting surface P8 may be a semi-circular arc shape to adapt to the cylindrical shaft member 13 .
所述第二轨迹S12为从第一卡位W1经所述第一面段P11的较高一端、第二过渡面段P22、第三面段P13、第三过渡面段P23到达所述第二面段P12的较低一端处的第二卡位W2的路径;所述第一轨迹S11和所述第二轨迹S12首尾连接,形成环形的所述滑移轨迹S1。The second trajectory S12 is from the first clamping position W1 through the higher end of the first surface segment P11, the second transition surface segment P22, the third surface segment P13, and the third transition surface segment P23 to the second transition surface segment. The path of the second clamping position W2 at the lower end of the surface segment P12; the first trajectory S11 and the second trajectory S12 are connected end to end to form the annular sliding trajectory S1.
如此,操作者通过手动带动船用推进器机身110相对固定座30旋转而从水下状态变动至水上状态时,轴件13沿第一轨迹S11从第二卡位W2变动至第一卡位W1,且在变动过程中,轴件13经过第一过渡面段P21时,将沿轴件13的轴向撞击第一面段P11而发出撞击信号(如撞击声或撞击产生的振动感);操作者接收到该撞击信号后,即可松开船用推进器机身110,使船用推进器机身110在自重作用下下压档位卡架10及其上的轴件13,将轴件13卡入第一卡位W1。卡于第一卡位W1的轴件13,首先受到船用推进器机身110的重力作用而不容易意外向上脱离第一卡位W1,其次,轴件13沿轴向弹性压合第一面段P11加上第一面段P11和第二面段P12之间的高差,使得轴件13无法或很难反向回到第二面段P12,进而阻止船用推进器机身110在外力干扰(如船体在水面上的颠簸)意外从水上状态变动至水下状态,确保使用安全。In this way, when the operator manually drives the marine propeller body 110 to rotate relative to the fixed base 30 and changes from the underwater state to the above-water state, the shaft 13 moves from the second locking position W2 to the first locking position W1 along the first trajectory S11 , and during the change process, when the shaft member 13 passes through the first transition surface segment P21, it will hit the first surface segment P11 along the axial direction of the shaft member 13 and send out an impact signal (such as an impact sound or a vibration sensation generated by the impact); operation After receiving the impact signal, the operator can release the marine propeller body 110, so that the marine propeller body 110 presses down the gear bracket 10 and the shaft 13 thereon under its own weight, and locks the shaft 13 Enter the first card slot W1. The shaft member 13 stuck in the first clamping position W1 is firstly affected by the gravity of the marine propeller body 110 and is not easy to accidentally escape upward from the first clamping position W1. Secondly, the shaft member 13 elastically presses the first surface segment along the axial direction. P11 plus the height difference between the first surface section P11 and the second surface section P12 makes it impossible or difficult for the shaft 13 to return to the second surface section P12, thereby preventing the marine propeller body 110 from being interfered by external forces ( Such as the bumping of the hull on the water) accidental change from the above water state to the underwater state to ensure safe use.
在一种实施方式中,第一面段P11的延伸方向和竖直方向Y呈一设定角度A1,A1大小在5-45°之间,如设置为15°、20°、30°等,且第一面段P11靠上的一端向远离分隔壁31a一侧倾斜,即第一过渡面段P21相对竖直方向Y倾斜设置。该设定角度A1设置在5°之下,将降低第一过渡面段P21阻碍轴件13脱出第一面段P11的能力,即,使用安全性高;而设置在45°以上则使得操作者通过旋转船用推进器机身110带动轴件13脱出第一卡位W1过渡至第三面段P13的难度增大,影响用户体验。如此,在轴件13卡于第一卡位W1(第一面段P11的下端)时,船体颠簸等外力使船用推进器机身110相对固定座30向上运动的趋势将受到倾斜的第一过渡面段P21的阻碍,且第一过渡面段P21将引导轴件13向远离第三面段P13一侧移动,增大了轴件13脱出第一面段P11进入第三面段P13的难度,使得在颠簸时,轴件13能够较可靠地保持在第一面段P11上,并倾向于在船用推进器机身110的重力作用下回位至第一面段P11底部的第一卡位W1处。In one embodiment, the extension direction of the first surface segment P11 and the vertical direction Y form a set angle A1, and the size of A1 is between 5-45°, such as 15°, 20°, 30°, etc., And the upper end of the first surface segment P11 is inclined toward the side away from the partition wall 31a, that is, the first transition surface segment P21 is inclined relative to the vertical direction Y. Setting the setting angle A1 below 5° will reduce the ability of the first transition surface segment P21 to prevent the shaft member 13 from escaping from the first surface segment P11, that is, the use safety is high; and setting it above 45° will make the operator By rotating the marine propeller body 110, it becomes more difficult to drive the shaft 13 out of the first locking position W1 and transition to the third surface section P13, which affects the user experience. In this way, when the shaft 13 is stuck in the first clamping position W1 (the lower end of the first surface section P11), the tendency of the marine propeller body 110 to move upward relative to the fixed base 30 due to external forces such as hull bumps will be affected by the first transition of tilt. The obstruction of the surface segment P21, and the first transition surface segment P21 will guide the shaft member 13 to move away from the third surface segment P13, increasing the difficulty of the shaft member 13 to escape from the first surface segment P11 and enter the third surface segment P13, This enables the shaft member 13 to be more reliably held on the first surface segment P11 during bumps, and tends to return to the first blocking position W1 at the bottom of the first surface segment P11 under the gravity of the marine propeller body 110 at.
当然,在其他实施例中,也可基于对用户体验和使用安全性两者的合理取舍,或采用补救措施的方式,将该设定角度A1设置在其他角度范围,如45-60°或0-5°。Of course, in other embodiments, the setting angle A1 can also be set in other angle ranges, such as 45-60° or 0, based on reasonable trade-offs between user experience and use safety, or by adopting remedial measures. -5°.
在一种实施方式中,所述第二过渡面段P22靠近所述第一面段P11一端位置较低、靠近所述第三面段P13一端位置较高,如图中所示的,第二过渡面段P22大致呈延伸方向与水平方向X呈设定夹角A2的状态,并在和第一面段P11上端连接处设过渡圆角P24,以利于平滑过渡。该设定夹角A2的大小可以设置在2-15°之间。通过使第二过渡面段P22靠近第三面段P13一端较高,使得在船体210颠簸等外界干扰力作用带来的轴件13相对固定座30的运 动趋势难以使轴件13经第二过渡面段P22进入第三面段P13,提高了使用安全性;并且,第二过渡面段P22倾斜设置,使得即使轴件13在外界干扰力的作用下意外移动至第二过渡面段P22上的某处,在干扰力作用停止后,轴件13也可在船用推进器机身110的重力作用下沿第二过渡面段P22下滑至第一面段P11,进而回位至第一卡位W1。In one embodiment, the second transition surface segment P22 has a lower end near the first surface segment P11 and a higher end near the third surface segment P13. As shown in the figure, the second The transition surface segment P22 is generally in a state where the extending direction and the horizontal direction X form a set angle A2, and a transition fillet P24 is provided at the connection with the upper end of the first surface segment P11 to facilitate smooth transition. The set angle A2 can be set between 2-15°. By making the end of the second transition surface segment P22 close to the third surface segment P13 higher, the movement tendency of the shaft member 13 relative to the fixed base 30 caused by external interference forces such as bumps of the hull 210 makes it difficult for the shaft member 13 to pass through the second transition surface. The surface segment P22 enters the third surface segment P13, which improves the safety of use; and the second transition surface segment P22 is set at an angle, so that even if the shaft member 13 accidentally moves to the second transition surface segment P22 under the action of external interference force, At some point, after the interference force stops, the shaft 13 can also slide down to the first surface section P11 along the second transition surface section P22 under the gravity of the marine propeller body 110, and then return to the first blocking position W1. .
配合参见图15和图16,在一种实施方式中,所述第二过渡面段P22还可设置为下边凹入深度较大、上边凹入深度较小的坡面。该坡面的坡角A3可设置在2-10°。该处所说的下边和上边为相对重力方向(即竖直方向Y)而言。通过该设置,结合沿轴向弹性支撑于轴件13的弹性件12的限制或阻碍,一定程度上限制了轴件13竖向向上移动以进入第二过渡面段P22的可能,利于在船用推进器100受到竖向颠簸等外界干扰力时,使轴件13保持在第一面段P11上而不易进入第二过渡面段P22或经过第二过渡面段P22进入第三面段P13。Referring to FIGS. 15 and 16 , in one embodiment, the second transition surface segment P22 may also be configured as a slope surface with a larger concave depth on the lower side and a smaller concave depth on the upper side. The slope angle A3 of the slope can be set at 2-10°. The lower and upper sides mentioned here are relative to the direction of gravity (that is, the vertical direction Y). Through this arrangement, combined with the restriction or obstruction of the elastic member 12 elastically supported on the shaft member 13 in the axial direction, the possibility of the shaft member 13 moving upward vertically to enter the second transition surface section P22 is limited to a certain extent, which is beneficial to ship propulsion. When the device 100 is subjected to external interference forces such as vertical bumps, the shaft member 13 is kept on the first surface segment P11 and is not easy to enter the second transition surface segment P22 or enter the third surface segment P13 through the second transition surface segment P22.
继续参见图12、图15和图16,本实施例中,所述第二过渡面段P22和所述第三面段P13之间呈第三面段P13一侧凹入深度较大的台阶形,如此,在操作者通过船用推进器机身110带动轴件13从第二过渡面段P22过渡到第三面段P13的过程中,轴件13可在弹性件12的作用下撞击第三面段P13,产生撞击信号(如撞击声或撞击产生的振动感)。操作者在接收到该撞击信号后即可停止用力,而使轴件13在船用推进器机身110的自重作用下沿第三面段P13下行,并经第三过渡面段P23进入第二卡位W2。即,该结构中,若需要船用推进器100从水上状态变动至水下状态(对应轴件13从第一卡位W1变动至第二卡位W2),操作者对船用推进器机身110的操作,只需使轴件13从第一卡位W1经过第一面段P11和第二过渡面段P22到第三面段P13上端即可,轴件13剩下的行程可利用船用推进器机身110自重带动,减少操作者需要用力的时间,提高用户体验。Continuing to refer to Figures 12, 15 and 16, in this embodiment, the second transition surface section P22 and the third surface section P13 are in the shape of a step with a larger concave depth on one side of the third surface section P13. , in this way, when the operator drives the shaft 13 to transition from the second transition surface section P22 to the third surface section P13 through the marine propeller fuselage 110, the shaft 13 can hit the third surface under the action of the elastic member 12 Section P13 generates impact signals (such as impact sounds or vibrations caused by impact). After receiving the impact signal, the operator can stop exerting force, and allow the shaft 13 to descend along the third surface section P13 under the weight of the marine propeller body 110, and enter the second clamp through the third transition surface section P23. Bit W2. That is, in this structure, if the marine propeller 100 needs to be moved from the above-water state to the underwater state (the corresponding shaft 13 moves from the first clamping position W1 to the second clamping position W2), the operator must adjust the position of the marine propeller fuselage 110. To operate, you only need to move the shaft 13 from the first clamping position W1 through the first surface section P11 and the second transition surface section P22 to the upper end of the third surface section P13. The remaining stroke of the shaft 13 can be made by using the marine propeller machine. The body 110 is driven by its own weight, reducing the time the operator needs to exert force and improving user experience.
在一种实施方式中,所述第三过渡面段P23为连接所述第三面段P13一端凹入深度较小、连接所述第二面段P12一端凹入深度较大的斜面。可选地,第三过渡面段P23与第三面段P13之间、第三过渡面段P23与第二面段P12之间平滑过渡。In one embodiment, the third transition surface segment P23 is an inclined surface with a smaller recessed depth at one end connected to the third surface segment P13 and a larger recessed depth at the end connected to the second surface segment P12. Optionally, there is a smooth transition between the third transition surface segment P23 and the third surface segment P13, and between the third transition surface segment P23 and the second surface segment P12.
通过第三过渡面段P23的斜面设置,当轴件13定位在第二卡位W2时,受弹性件12轴向弹性力的限制,轴件13不容易通过第三过渡面段P23反向回到第三面段P13,即能够一定程度上保持轴件13定位于第二卡位W2,避免因船体210颠簸等外界干扰力使轴件13从第二卡位W2脱出,提高使用安全性。Through the inclined surface of the third transition surface segment P23, when the shaft member 13 is positioned at the second locking position W2, limited by the axial elastic force of the elastic member 12, the shaft member 13 cannot easily return through the third transition surface segment P23. By the third surface section P13, the shaft 13 can be kept positioned at the second locking position W2 to a certain extent, preventing the shaft 13 from coming out of the second locking position W2 due to external interference forces such as bumps of the hull 210, thereby improving the safety of use.
通过上述设置,能够可靠地保证了船用推进器100在各卡位的稳定性,提高使用环境适应能力和使用安全性,并具有良好的用户体验。Through the above settings, the stability of the marine propeller 100 in each position can be reliably guaranteed, the adaptability to the use environment and the safety of use can be improved, and a good user experience can be achieved.
参见图17-图19,第二档位槽C2的槽侧面P4的外轮廓(指第二档位槽C2的槽侧面P4在第二表面P2的投影的外轮廓)可设置为与第一档位槽C1的槽侧面P3的外轮廓一致或基本一致,两者沿轴件13的轴向正对,以保持轴件13的两端能够同步地支撑于第一档位槽C1和第二档位槽C2的不同位置。例如,第二档位槽C2的槽侧面P4在对应第一卡位W1或第二卡位W2处,也设置有对应第一档位槽C1的槽侧面P3处设置的各凹口,用于支撑轴件13的对应端。Referring to Figures 17-19, the outer contour of the groove side P4 of the second gear groove C2 (referring to the outer contour of the projection of the groove side P4 of the second gear groove C2 on the second surface P2) can be set to be the same as that of the first gear groove C2. The outer contours of the groove side P3 of the position groove C1 are consistent or substantially consistent, and they are directly opposite along the axial direction of the shaft member 13 to ensure that both ends of the shaft member 13 can be synchronously supported on the first gear slot C1 and the second gear slot C1. Different positions of bit slot C2. For example, the slot side P4 of the second gear slot C2 is also provided with notches corresponding to the slot side P3 of the first gear slot C1 at the position corresponding to the first clamping position W1 or the second clamping position W2. The corresponding end of the shaft 13 is supported.
如前文描述,轴件13的一端端面被弹性压抵于第一档位槽C1的槽底面P5,另一端端面对应第二档位槽C2的槽底面P6,且可设置得与第二档位槽C2的槽底面P6相间隔。即,第二档位槽C2的槽底面P6基本不用于引导轴件13的轴向移动,只需不影响阻碍轴件13的轴向移动即可。因此,本实施例中,第二档位槽C2的槽底面P6大致为一与轴件13的轴线平 行的平面,以减少设计和加工难度。As described above, one end surface of the shaft 13 is elastically pressed against the groove bottom surface P5 of the first gear groove C1, and the other end surface corresponds to the groove bottom surface P6 of the second gear groove C2, and can be arranged to be in line with the second gear groove C2. The groove bottom P6 of groove C2 is spaced apart. That is, the groove bottom surface P6 of the second gear groove C2 is basically not used to guide the axial movement of the shaft member 13 , and only needs to not affect or hinder the axial movement of the shaft member 13 . Therefore, in this embodiment, the groove bottom surface P6 of the second gear groove C2 is generally a plane parallel to the axis of the shaft member 13, so as to reduce the difficulty of design and processing.
当然,在一些实施方式中,在第二档位槽C2的槽底面P6处也可根据需要设置一些辅助结构,来辅助限制轴件13在一些位置的轴向跳动或用于提高轴件13移动的平顺性。Of course, in some embodiments, some auxiliary structures may also be provided at the groove bottom surface P6 of the second gear groove C2 as needed to assist in limiting the axial runout of the shaft member 13 at some positions or to improve the movement of the shaft member 13 of smoothness.
例如,所述第二档位槽C2的槽底面P6设置对应所述第一面段P11的第一对应面P31和对应所述第二过渡面段P22的第二对应面P32,所述第二对应面P32连接于所述第一对应面P31位置较高一端,所述第二对应面P32为下边凹入深度较大、上边凹入深度较小的坡面。所述第一对应面P31连接所述第二对应面P32一端设有对应过渡面段P33,用于所述第一对应面P31和所述第二对应面P32的过渡连接。第一对应面P31和第二对应面P32能够减小轴件13在抵顶于第一面段P11和第二过渡面段P22部分区域的轴向跳动范围,从而辅助限制轴件13在外界干扰力作用下的移动,提高使用安全。对应过渡面段P33提高第二档位槽C2的槽底面P6的平顺性,亦可避免在意外情况下,轴件13被卡止于第二档位槽C2的槽底面P6的平面部分和第一对应面P31之间的台阶处。For example, the groove bottom surface P6 of the second gear groove C2 is provided with a first corresponding surface P31 corresponding to the first surface segment P11 and a second corresponding surface P32 corresponding to the second transition surface segment P22. The corresponding surface P32 is connected to the higher end of the first corresponding surface P31, and the second corresponding surface P32 is a slope surface with a larger concave depth on the lower side and a smaller concave depth on the upper side. A corresponding transition surface segment P33 is provided at one end of the first corresponding surface P31 connected to the second corresponding surface P32 for transitional connection between the first corresponding surface P31 and the second corresponding surface P32.
