Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of mechanical motion control systems, and more particularly, to a control device and working method for single-motor control of double-output linear motion. Background Art
[0002] Currently, water operation equipment is usually powered by an outboard motor. For the control of the gear position and throttle of the outboard motor, a manual control device is used, such as a manual throttle knob and a shift lever; some systems use two electric linear actuators to control the throttle and gear position respectively by pulling a cable through the electric actuator to ensure independent adjustment of the two. Since the throttle cannot be adjusted when the outboard motor is shifting gears, and the gear position cannot be adjusted when adjusting the throttle, if the operation is improper, it is easy to cause danger, damage the outboard motor, and reduce the reliability of the rescue equipment during use.
[0003] Currently, a single control box is used to pull two cables. Although this method can effectively solve the control problem, since it is impossible to strictly ensure the linear movement of the cables, most control boxes will cause the cables to deform during the pulling process, thus affecting the normal adjustment of the gear position and throttle.

[0064] When the outer convex locking arc 603 and the inner concave locking arc 605 coincide during the rotation process, the grooved wheel 602 and the driven cam assembly 5 are locked simultaneously.
[0065] Embodiment 1
[0066] This embodiment is to solve the problem that the current outboard gear shift and throttle control need to be controlled by two electric linear actuators respectively, the control operation is relatively complex, problems are likely to occur during the control process, which may damage the outboard engine and reduce the reliability of the rescue equipment. Therefore, the following solution is disclosed. For details, please refer to Figures 1-10 as shown in the figure: It includes a support base 1, a power input component 2 and a linear output component 3; the power input component 2 and the linear output component 3 are arranged on the support base 1; the linear output component 3 is composed of a driving cam component 4, a driven cam component 5 and a grooved wheel component 6.
[0067] The driving cylindrical cam 401 in the linear output component 3 is provided with a card slot; the card slot is set as the driving cam horizontal slot 404 and the driving cam inclined slot 405, and the card slot track is designed through the preset angle of the motor; the developed line of the card slot is in a symmetric shape, and the axial projection length of the developed line is equal to the circumference of the cylindrical cross-section, so it can ensure that the card slot is closed and smoother on the driving cylindrical cam 401.
[0068] When the first driven pin 402 is within the range of the driving cam horizontal slot 404 of the driving cylindrical cam 401, there is no physical contact between the driving cylindrical cam 401 and the first driven pin 402, and the first driven pin 402 will not have a linear displacement;
[0069] When the first driven pin 402 is within the range of the active cam groove 405 of the active cylindrical cam 401, physical contact occurs between the active cylindrical cam 401 and the first driven pin 402 at this time. The active cam groove 405 outputs an oblique thrust to the first driven pin 402. Due to the constraint of a moving pair exerted by the first guide rail 403 on the first driven pin 402, the first driven pin 402 will move linearly along the first guide rail 403 under the drive of the active cylindrical cam 401.
[0070] A card slot is provided on the driven cylindrical cam 501 in the driven cam assembly 5; the card slot is arranged similarly to the active cylindrical cam 401, including a driven cam horizontal groove 504 and a driven cam oblique groove 505; the developed line of the card slot is in a symmetric shape, and the axial projection length of the developed line is equal to the circumference of the cylindrical cross-section, so it can ensure that the card slot is closed and smoother on the driven cylindrical cam 501.
[0071] The driven cylindrical cam 501 is connected to the sprocket 602 by a key. When the sprocket 602 rotates, it drives the driven cylindrical cam 501 to rotate.
[0072] When the second driven pin 502 is within the range of the driven cam horizontal groove 504 of the driven cylindrical cam 501, physical contact does not occur between the driven cylindrical cam 501 and the second driven pin 502 at this time, and the driven pin does not undergo linear displacement.
[0073] When the second driven pin 502 is within the range of the driven cam oblique groove 505 of the driven cylindrical cam 501, physical contact occurs between the driven cylindrical cam 501 and the second driven pin 502 at this time. The driven cam oblique groove 505 outputs an oblique thrust to the second driven pin 502. Due to the constraint of a moving pair exerted by the second guide rail 503 on the second driven pin 502, the second driven pin 502 will move linearly along the second guide rail 503 under the drive of the driven cylindrical cam 501;
[0074] When the active cylindrical cam 401 rotates, it drives the driving wheel 601 to rotate. When the pin 604 enters the radial groove 606, it pushes the sprocket 602 to rotate.
[0075] The sprocket assembly 6 plays a connecting role between the active cam assembly 4 and the driven cam assembly 5 in the linear output assembly 3 during the overall movement process. The sprocket assembly 6 can not only enable the active cam assembly 4 to drive the driven cam assembly 5 to move, but also, through the setting of the outer convex locking arc 603 and the inner concave locking arc 605, mechanically lock the sprocket 602 when the driving wheel 601 rotates 60°, achieving the effect that the two driven pins do not move simultaneously.
[0076] Embodiment 2
[0077] On the basis of the first embodiment, as Figure 11 shown: The groove track design on the driving cylindrical cam 401 and the driven cylindrical cam 501 realizes the linear straight-line output of the two driven pins step by step when the motor 201 rotates; and the developed views of the groove tracks of the driving cylindrical cam 401 and the driven cylindrical cam 501 are symmetrical, and it is a columnar groove that is connected end to end on the cam. Such a design can not only achieve the symmetry of the movement, but also better protect the entire structure in the case of abnormal external input.
[0078] This device is applied to the shift throttle cable of the outboard motor. The second driven pin 502 on the driven cylindrical cam 501 is connected to the shift cable, and the first driven pin 402 on the driving cylindrical cam 401 is connected to the throttle cable;
[0079] In the first stage (the driving cam rotates 0° - 60°), the first driven pin 402 on the driving cylindrical cam 401 does not have a linear displacement, and the second driven pin 502 on the driven cylindrical cam 501 has a linear displacement;
[0080] In the second stage (the driving wheel rotates 60° - 180°), the driven pin on the driving cam has a linear displacement, but since the outer convex locking arc 603 on the driving wheel 601 locks the inner concave locking arc 605 on the grooved wheel 602, the grooved wheel 602 will not rotate, and thus will not drive the second driven pin 502 on the driven cylindrical cam 501 to have a linear motion.
[0081] Embodiment Three
[0082] On the basis of the second embodiment, as Figures 1-11 shown: When the motor 201 drives the driving cylindrical cam 401 to rotate 60° clockwise from the starting position, since the track design of the driving cam horizontal groove 404 of the driving cylindrical cam 401 is horizontal in this part, at this time, the driving cylindrical cam 401 will not generate an axial component force on the first driven pin 402. Therefore, the linear displacement of the first driven pin 402 of the driving cylindrical cam 401 will not change;
[0083] Meanwhile, the driven cylindrical cam 501 is driven by the grooved wheel 602 to rotate counterclockwise. Due to the special structure of the grooved wheel 602, when the driving wheel 601 rotates out of the position of the grooved wheel 602, the angle between the normal of the speed and the U-shaped groove is exactly 90°. According to this geometric relationship, the rotation angle of the grooved wheel 602 can be obtained as 30°. At this stage, the track of the driven cam chute 505 of the driven cylindrical cam 501 will give a component force to the second driven pin 502 in the axial direction, causing the second driven pin 502 to move within the card slot of the driven cylindrical cam 501 and slide to output linear motion under the restriction of the second guide rail 503; when the grooved wheel 602 is driven by the driving wheel 601 to rotate counterclockwise by 30°, the second driven pin 502 on the driven cylindrical cam 501 will move from the middle position (the starting position of the driven pin) to one end of the driven cylindrical cam 501.
[0084] After the driving cylindrical cam 401 rotates by an angle exceeding 60°, the card slot on the driving cylindrical cam 401 will contact the first driven pin 402, thus giving an axial component force to the first driven pin 402, and due to the action of the first guide rail 403, the first driven pin 402 slides on the first guide rail 403 to output linear motion.
[0085] When the rotation range of the driving cylindrical cam 401 is between 60° and 180°, the first driven pin 402 on the driving cylindrical cam 401 will move from one end to the other end on the driving cylindrical cam 401, and this distance is also the feasible distance of the first guide rail 403;
[0086] Meanwhile, when the rotation angle of the driving cylindrical cam 401 exceeds 60°, the pin 604 on the driving wheel 601 will move out of the radial groove 606 of the grooved wheel 602, and the outer convex locking arc 603 on the driving wheel 601 locks the inner concave locking arc 605 on the grooved wheel 602, which not only ensures that the driving wheel 601 will not drive the grooved wheel 602 to rotate, but also realizes the locking of the grooved wheel 602 in terms of structure.
[0087] Similarly, when the driving cylindrical cam 401 rotates counterclockwise by 60° from the starting position, the first driven pin 402 on the driving cylindrical cam 401 will also remain stationary, while the second driven pin 502 on the driven cylindrical cam 501 slides along the second guide rail 503 to output linear motion. When the rotation angle exceeds 60°, the first driven pin 402 on the driving cylindrical cam 401 slides along the first guide rail 403 to output linear motion, and at the same time plays a role in locking the driven cam assembly 5.
[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
