Description

Technical Field

[0001] The present invention relates to the technical field of mechanical motion control systems, and in particular to a control device and a working method for controlling dual-output linear motions with a single motor. Background Art

[0002] At present, water operation equipment is usually powered by outboard motors. The gear and throttle of the outboard motor are controlled by manually operated control devices, such as a manual throttle knob and a shift lever; some systems use two electric linear actuators to control the throttle and gear respectively by pulling the pull wire through the electric actuator to ensure independent adjustment of the two. Since the throttle of the outboard motor cannot be adjusted when shifting gears, and the gear cannot be adjusted when adjusting the throttle, improper operation may easily cause danger and damage to the outboard motor, reducing the reliability of the rescue equipment when in use.

[0003] Currently, a single control box is used to pull two cables. Although this method can effectively solve the control problem, it cannot strictly guarantee 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 and throttle. Summary of the invention

[0014] The present invention also provides a working method of a control device for controlling dual-output linear motion with a single motor, based on the above-mentioned control device for controlling dual-output linear motion with a single motor, comprising the following steps: Turn on the motor to output power, the motor drives the bevel gear to rotate, and the bevel gear rotates to drive the active cylindrical cam to rotate; When the active cylindrical cam rotates, the first driven pin is pushed through the slot of the active cylindrical cam, so that the first driven pin slides on the first guide rail, and a linear displacement change occurs; one end of the active cylindrical cam is connected to the bevel gear, and the other end is connected to the driving wheel through a key; The pin on the driving wheel is inserted into the radial groove of the groove wheel at the initial position, and the groove wheel is driven to rotate by the rotation of the driving wheel; When the active cylindrical cam rotates, the groove wheel is driven to rotate through the driving wheel, and when the groove wheel rotates, the driven cylindrical cam is driven to rotate; When the driven cylindrical cam rotates, the second driven pin is pushed toward the second driven pin through the clamping groove of the driven cylindrical cam, so that the second driven pin slides on the second guide rail, and a linear displacement change occurs; When the outer convex locking arc and the inner concave locking arc coincide with each other during the rotation process, the groove wheel and the driven cylindrical cam assembly are locked at the same time.

[0041] The clamping grooves on the active cylindrical cam 401 are configured as an active cam horizontal groove 404 and an active cam oblique groove 405 ; the clamping grooves on the driven cylindrical cam 501 are configured as a driven cam horizontal groove 504 and a driven cam oblique groove 505 .

[0042] The groove tracks of the active cylindrical cam 401 and the driven cylindrical cam 501 are set differently; the time and position of movement of the first driven pin 402 and the second driven pin 502 are different.

[0043] The slot tracks of the active cylindrical cam 401 and the driven cylindrical cam 501 are set differently, and the slot tracks designed with special dimensions ensure the linear output of the two driven pins. This design ensures that the two driven pins move at different times and positions, so that their linear output can maintain a linear relationship.

[0044] A pin 604 is provided at the front end of the driving wheel 601 ; the outer ring profile of the driving wheel 601 is set as an outer convex locking arc 603 ; the circular motion arc trajectory of the pin 604 is designed to be concentric with the outer convex locking arc 603 .

The concave locking arcs 605 provided at the top and bottom are symmetrically arranged. The radial groove 606 is a U-shaped groove.

[0046] A working method of a control device for controlling dual-output linear motion with a single motor, comprising the following steps: Turn on the motor 201 to output power, the motor 201 drives the bevel gear 202 to rotate, and the bevel gear 202 drives the active cylindrical cam 401 to rotate when rotating; When the active cylindrical cam 401 rotates, the first driven pin 402 is pushed by the slot of the active cylindrical cam 401, so that the first driven pin 402 slides on the first guide rail 403, and a linear displacement changes; one end of the active cylindrical cam 401 is connected to the bevel gear 202, and the other end is connected to the driving wheel 601 through a key; The pin 604 on the driving wheel 601 is inserted into the radial groove 606 of the groove wheel 602 at the initial position, and the groove wheel 602 is driven to rotate by the rotation of the driving wheel 601; When the active cylindrical cam 401 rotates, the groove wheel 602 is driven to rotate through the driving wheel 601, and when the groove wheel 602 rotates, the driven cylindrical cam 501 is driven to rotate; When the driven cylindrical cam 501 rotates, the slot of the driven cylindrical cam 501 pushes the second driven pin 502, so that the second driven pin 502 slides on the second guide rail 503, and a linear displacement changes. When the convex locking arc 603 and the concave locking arc 605 overlap during the rotation, the groove wheel 602 and the driven cam assembly 5 are locked at the same time.

[0047] Embodiment 1 In order to solve the problem that the current outboard motor gear position and throttle control need to be controlled by two electric linear actuators respectively, the control operation is relatively complicated, problems are prone to occur during the control process, damage to the outboard motor, and reduced reliability of the rescue equipment, the following solution is disclosed. For details, please refer to Figure 1-10 As shown: it includes a supporting base 1, a power input assembly 2 and a linear output assembly 3; the power input assembly 2 and the linear output assembly 3 are arranged on the supporting base 1; the linear output assembly 3 is composed of an active cam assembly 4, a driven cam assembly 5 and a groove wheel assembly 6.

[0048] A card slot is provided on the active cylindrical cam 401 in the linear output component 3; the card slot is set as an active cam horizontal slot 404 and an active cam inclined slot 405, and the card slot trajectory is designed by a preset angle of the motor; the expansion line of the card slot is in a pair shape, and the axial projection length of the expansion line is equal to the circumference of the cylindrical cross section, so it can be ensured that the card slot on the active cylindrical cam 401 is closed and smoother.

[0049] When the first follower pin 402 is within the range of the active cam horizontal groove 404 of the active cylindrical cam 401, no physical contact occurs between the active cylindrical cam 401 and the first follower pin 402, and the first follower pin 402 does not undergo linear displacement; When the first follower pin 402 is within the range of the active cam bevel groove 405 of the active cylindrical cam 401, physical contact occurs between the active cylindrical cam 401 and the first follower pin 402, and the active cam bevel groove 405 outputs an oblique thrust to the first follower pin 402. Since the first guide rail 403 has a moving pair constraint on the first follower pin 402, the first follower pin 402 will move in a straight line along the first guide rail 403 driven by the active cylindrical cam 401.

[0050] A slot is provided on the driven cylindrical cam 501 in the driven cam assembly 5; the slot is similar to that of the active cylindrical cam 401, including a driven cam horizontal slot 504 and a driven cam oblique slot 505; the unfolding line of the slot is in a pairing shape, and the axial projection length of the unfolding line is equal to the circumference of the cylindrical cross section, so it can be ensured that the slot on the driven cylindrical cam 501 is closed and smoother.

[0051] The driven cylindrical cam 501 is connected to the groove wheel 602 through a key. When the groove wheel 602 rotates, the driven cylindrical cam 501 is driven to rotate.

[0052] When the second follower pin 502 is within the range of the follower cam horizontal groove 504 of the follower cylindrical cam 501 , there is no physical contact between the follower cylindrical cam 501 and the second follower pin 502 , and the follower pin will not undergo linear displacement.

[0053] When the second follower pin 502 is within the range of the follower cam bevel groove 505 of the follower cylindrical cam 501, the follower cylindrical cam 501 and the second follower pin 502 are in physical contact, and the follower cam bevel groove 505 outputs an oblique thrust to the second follower pin 502. Since the second guide rail 503 has a moving pair constraint on the second follower pin 502, the second follower pin 502 will perform a linear motion along the second guide rail 503 under the drive of the follower cylindrical cam 501. When the active cylindrical cam 401 rotates, it drives the driving wheel 601 to rotate, and when the pin 604 enters the radial groove 606, it drives the groove wheel 602 to rotate.

[0054] The groove wheel 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 groove wheel assembly 6 can not only realize the movement of the driven cam assembly 5 by the active cam assembly 4, but also mechanically lock the groove wheel 602 when the driving wheel 601 rotates 60° through the setting of the convex locking arc 603 and the concave locking arc 605, thereby achieving the effect that the two driven pins will not move at the same time.

[0055] Embodiment 2 This embodiment is based on the first embodiment. Fig.11As shown: the slot track design on the active cylindrical cam 401 and the driven cylindrical cam 501 enables the two driven pins to achieve linear straight line output in steps when the motor 201 rotates; and the expansion diagram of the slot track of the active cylindrical cam 401 and the driven cylindrical cam 501 is symmetrical, and there is a cylindrical groove connected end to end on the cam. Such a design can not only achieve the symmetry of movement, but also prevent the abnormal external input and better protect the entire structure.

[0056] The device is applied to the outboard motor gear throttle cable, the second follower pin 502 on the follower cylindrical cam 501 is connected to the gear cable, and the first follower pin 401 on the active cylindrical cam 401 is connected to the throttle cable; In the first stage (the active cam rotates 0°-60°), the first follower pin 402 on the active cylindrical cam 401 does not undergo linear displacement, and the second follower pin 502 on the driven cylindrical cam 501 undergoes linear displacement; In the second stage (the driving wheel rotates 60°-180°), the follower pin on the driving cam undergoes linear displacement, but since the convex locking arc 603 on the driving wheel 601 locks the concave locking arc 605 on the groove wheel 602, the groove wheel 602 will not rotate, and will not drive the second follower pin 502 on the driven cylindrical cam 501 to move linearly.

[0057] Embodiment 3 This embodiment is based on the second embodiment. Figure 1-11 As shown in the figure, when the motor 201 drives the active cylindrical cam 401 to rotate 60° clockwise from the starting position, since the track design of the active cam horizontal groove 404 of the active cylindrical cam 401 in this part is horizontal, the active cylindrical cam 401 will not generate an axial component force on the first driven pin 402, so the first driven pin 402 of the active cylindrical cam 401 will not undergo a linear displacement change; At the same time, the driven cylindrical cam 501 is driven by the groove wheel 602 to rotate counterclockwise. According to the particularity of the structure of the groove wheel 602, when the driving wheel 601 rotates out of the position of the groove 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 groove wheel 602 is 30°. At this stage, the driven cam inclined groove 505 track of the driven cylindrical cam 501 will give a component force to the second driven pin 502 in the axial direction, so that the second driven pin 502 will move in the slot of the driven cylindrical cam 501, so that it slides and outputs linear motion under the restriction of the second guide rail 503; when the groove wheel 602 is driven by the driving wheel 601 to rotate 30° counterclockwise, 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.

[0058] When the active cylindrical cam 401 rotates more than 60°, the slot on the active cylindrical cam 401 will contact the first follower pin 402, thereby giving the first follower pin 402 an axial component force, and due to the action of the first guide rail 403, the first follower pin 402 slides on the first guide rail 403 to output linear motion.

[0059] When the active cylindrical cam 401 rotates within a range of 60°-180°, the first follower pin 402 on the active cylindrical cam 401 will move from one end to the other end on the active cylindrical cam 401, and this distance is also a feasible distance of the first guide rail 403; At the same time, when the active cylindrical cam 401 rotates at an angle exceeding 60°, the pin 604 on the driving wheel 601 will move out from the radial groove 606 of the groove wheel 602, and the convex locking arc 603 on the driving wheel 601 will lock the concave locking arc 605 on the groove wheel 602, thereby ensuring that the driving wheel 601 will not rotate with the groove wheel 602 and structurally locking the groove wheel 602.

[0060] Similarly, when the active cylindrical cam 401 rotates 60° counterclockwise from the starting position, the first follower pin 402 on the active cylindrical cam 401 will remain stationary, and at the same time, the second follower pin 502 on the driven cylindrical cam 501 slides along the second guide rail 503 to output a linear motion. When the rotation angle exceeds 60°, the first follower pin 402 on the active cylindrical cam 401 slides along the first guide rail 403 to output a linear motion, and at the same time locks the driven cam assembly 5.

[0061] 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 aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, 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.
