[0044] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] like Figure 1 As shown, the present invention also proposes a foldable foot control device, including a control box body 1, a lifting mechanism 2, a foot pedal mechanism 3 and a side cover plug assembly 4; the lower end of the lifting mechanism 2 is connected to the control box body 1, and the foot pedal mechanism 3 is connected to the upper end of the lifting mechanism 2; the side cover plug assembly 4 is detachably installed on the side of the control box body 1, and is connected to the foot pedal mechanism 3 through a signal line.

[0046] like Figures 1 to 6 As shown, the lifting mechanism 2 includes a fixed support 216, a lower rocker arm 21, an upper rocker arm 22, an upper rotating shaft 29 and a lower step shaft 212; the fixed support 216 is fixedly connected to the control box body 1 by screws, and the lower end of the lower rocker arm 21 is rotatably connected to the fixed support 216 through the lower step shaft 212; the upper rocker arm 22 and the lower rocker arm 21 are rotatably connected through the upper rotating shaft 29, and the upper end of the upper rocker arm 22 is rotatably connected to the pedal mechanism 3 through the pin shaft 34.

[0047] Among them, a lower fixed wheel 213 is provided on the axial side of the lower end of the lower rocker arm 21, and the lower fixed wheel 213 is rotatably connected with the hole axis of the lower step shaft 212; a synchronous cam 222 is provided on the axial side of the lower end of the upper rocker arm 22, and a synchronous belt 211 is installed between the synchronous cam 222 and the lower fixed wheel 213, and the synchronous belt 211 on the outside of the synchronous cam 222 is fixed by a locking screw 28, and the synchronous belt 211 on the outside of the lower fixed wheel 213 is fixed by a pressing plate 214 and a screw; in addition, the lower fixed wheel 213 is fixed to the fixed support 216 by screws.

[0048] When the upper rocker arm 22 rotates counterclockwise by a certain angle, due to the presence of the synchronous belt 211, the lower rocker arm 21 rotates clockwise by the same angle relative to the lower step shaft 212; thereby transmitting the rotation angle of the upper rocker arm to the lower rocker arm, so that the lower rocker arm 21 and the upper rocker arm 22 rotate synchronously in opposite directions by the same angle.

[0049] A magnet fixture 27 is fixed to the other axial end of the lower rocker arm 21, and a circular magnet 26 is fixedly mounted on the magnet fixture 27. The side cover plug assembly 4 is located axially outward from the lower rocker arm 21 and comprises a cover 42, a socket circuit board 43, and a fixed socket 41. An angle sensing chip 431 is mounted on the socket circuit board 43, and is positioned opposite the circular magnet 26. The circular magnet 26 has an N pole and a S pole, and the angle sensing chip 431 is essentially a magnetic encoder.

[0050] When the lower rocker arm 21 drives the circular magnet 26 to rotate, the angle sensing chip 431 can accurately detect the rotation angle of the circular magnet 26, and then determine the rotation angle of the lower rocker arm 21 and the upper rocker arm 22, and then determine the magnitude of the force applied by the user to the pedal mechanism 3, and finally input the electromagnetic signal of the angle sensing chip 431 to the acceleration and deceleration actuator to control the acceleration and deceleration of the entire yacht.

[0051] Among them, the fixed socket 41 is fixedly installed on the box cover 42 and is sealed. The inner end of the fixed socket 41 is electrically connected to the socket circuit board 43, and the outer end of the fixed socket 41 can be detachably connected to a plug that matches it; thereby transmitting the signal input on the socket circuit board 43.

[0052] Specifically, if Figures 7 to 11 As shown, the pedal mechanism 3 includes a pedal base 35, a sliding plate 36 and a steering circuit board assembly 38; the sliding plate 36 is arranged at the upper end of the pedal base 35 and slides left and right through a sliding guide mechanism, and the steering circuit board assembly 38 is arranged at the lower end of the pedal base 35, and has a steering control circuit board 381 and a plurality of Hall switches 382. At the same time, an induction magnet 363 is provided on the sliding plate 36. The sliding plate 36 drives the induction magnet 363 to move left and right, and is sensed by different Hall switches 382 during the process, so that the steering control circuit board outputs a signal to the actuator to execute steering commands of different gears.

[0053] Among them, a slider placement groove 357 is provided at the upper end of the pedal base 35, a guide slider 364 is fixedly installed on the back of the sliding plate 36, and the induction magnet 363 is fixedly installed on the guide slider 364. In addition, a guide rod 356 extending in the left and right directions is also provided in the slider placement groove 357, and a groove matching the guide rod 356 is provided on the back of the guide slider 364; the sliding guidance of the induction magnet 363 is realized by matching the slider placement groove 357 and the guide rod 356 with the guide slider 364 respectively.

[0054] A pair of positioning cams 366 are provided at the upper end of the guide slider 364, and a positioning hole corresponding to the positioning cams 366 is provided on the sliding plate 36, so that the guide slider 364 and the sliding plate 36 are accurately positioned, and it is beneficial to the installation and fixation of the guide slider 364 and the induction magnet 363.

[0055] The user presses one foot on the anti-slip pad 31 and applies force to the left or right; the sliding plate 36 moves with the anti-slip pad 31 and drives the guide slider 364 to move along the guide rod 356, while driving the induction magnet 363 to move to one of the several Hall switches facing the induction magnet and obtaining a magnetic signal; the circuit board receives the electromagnetic signal input by the Hall switch and determines the steering gear; the circuit board inputs an electrical signal to the actuator through the data line, and the actuator controls the steering of the device.

[0056] In one embodiment, if Figure 5 As shown, a lower rocker arm support plate 210 is further provided on one axial side of the lower rocker arm 21, and the lower end of the lower rocker arm support plate 210 is fixedly connected to the lower part of the lower rocker arm 21. At the same time, the lower rocker arm support plate 210 is connected to the upper rotating shaft 29, and the two are circumferentially positioned by the cooperation of the limiting boss and the limiting groove to prevent the upper rotating shaft 29 from rotating at will and causing the fixing bolts to loosen.

[0057] like Figure 5 As shown, a return torsion spring 215 is sleeved on the lower step shaft 212, and one end of the return torsion spring 215 is in conflict with the lower rocker arm 21; the other end of the return torsion spring 215 is in conflict with the fixed support 216. By setting the return torsion spring 215, the lifting mechanism 2 can automatically bounce open and reset, avoiding the lower rocker arm 21 from staying in the acceleration position.

[0058] like Figure 3 、 Figure 4 As shown, the foot pedal mechanism 3 also includes a button trigger plate 32 and a reset torsion spring 37; the pedal connecting ear plate 358 at the lower end of the pedal base 35 is connected to the upper end of the upper rocker arm 22 through a pin shaft 34, and the reset torsion spring 37 is sleeved on the pin shaft 34, and the two ends of the reset torsion spring 37 are respectively in contact with the pedal base 35 and the upper rocker arm 22.

[0059] In order to prevent the pedal base 35 from rotating too much around the reset torsion spring 237, a limit boss 221 is provided at the upper end of the upper rocker arm 22, and the limit boss 221 cooperates with the pedal connecting ear plate 358; when the user does not apply force to the foot pedal mechanism 3, the pedal base returns to the initial angle, and the initial angle is ergonomic.

[0060] The key trigger plate 32 is also mounted on the pin shaft 34. At the same time, a reset torsion spring 39 is installed in the key trigger plate 32. The two ends of the reset torsion spring 39 respectively contact the key trigger plate 32 and the pedal base 35. In addition, the steering circuit board assembly 38 is detachably mounted on the bottom of the pedal base 35. A key ring 383 is provided on the steering circuit board assembly 38. The position of the key ring 383 is opposite to the movable end of the key trigger plate 32. When the key trigger plate contacts the key ring and clicks different times, the steering circuit board assembly 38 generates forward and reverse signals.

[0061] In the natural state, the reset torsion spring 39 forces the movable end of the key trigger plate 32 to not contact the key ring 383. When the user taps the pedal base 35 forward, the pedal base 35 rotates a certain angle around the pin shaft 34, and the movable end of the key trigger plate 32 clicks on the key ring 383, thereby inputting a control signal to the steering control circuit board 381 arranged on the inner side of the key ring 383. The steering control circuit board 381 determines the type of control signal and inputs a forward or backward signal to the acceleration and deceleration actuator through the data line.

[0062] like Figure 6 、 Figure 4 As shown, in order to facilitate debugging and achieve better waterproof effect; a plurality of spring pin contact points 432 are provided on the socket circuit board 43, a spring pin connector seat 23 is provided on the fixed support 216, a plurality of spring pins 25 are provided in the spring pin connector seat 23, and the rear end of the spring pin 25 is electrically connected to the steering control circuit board 381 through a data line; the plurality of spring pins 25 are respectively in contact with the plurality of spring pin contact points 432 to achieve electrical connection; in addition, a sealing gasket 24 is provided at one end of the spring pin connector seat 23 that contacts the control box body 1 to achieve a waterproof effect.

[0063] In addition, if Figure 1 and Figure 3 As shown, a limit buckle 33 is provided at the bottom front side of the pedal base 35, and a corresponding buckle movable locking mechanism 11 is provided at the upper end of the control box body 1. When the user presses the entire foot pedal mechanism 3 downward, the lifting mechanism 2 is folded, and the limit buckle 33 and the movable locking mechanism 11 are snap-fitted; the foot pedal mechanism 3 is buckled onto the top of the control box body 1, thereby achieving folding, volume reduction, waterproofing and other effects.

[0064] like Figure 5 As shown, a nylon pad is provided between the lower fixed wheel 213 and the lower rocker arm 21. The nylon pad serves as an axial limit and reduces the friction between the two. Similarly, a nylon pad is also provided at the position where the upper rocker arm 22 is opposite to the lower rocker arm 21. In addition, a nylon pad is also provided at the position where the upper rocker arm 22 is opposite to the lower rocker arm support plate 210.

[0065] In another embodiment, Figures 8 to 10 As shown, several Hall switches 382 are mounted on the steering circuit board assembly 38, corresponding to several blind positioning holes 362 on the back of the sliding plate 36. The pedal base 35 also includes a recess for mounting a positioning ball 351 and a compression spring. The number and spacing of the blind positioning holes 362 correspond to the number and spacing of the Hall switches 382. As the sliding plate 36 slides left and right, the positioning ball 351 slides into different blind positioning holes 362, aligning the corresponding sensing magnet with a Hall switch 382. This generates a stable electromagnetic signal for the Hall switch 382. Simultaneous occurrence of adjacent Hall signals is evaluated by software as an effective value.

[0066] like Figure 8 、 Figure 9As shown, a sliding guide mechanism is provided between the sliding plate 36 and the pedal base 35, and the sliding guide mechanism includes: a pressure plate 361, a guide slot 352 and a plurality of fixing bolts; wherein, the guide slot 352 is provided on the pedal base 35 and extends in the left and right directions; a plurality of fixing bolts pass through the guide slot 352 and fix the pressure plate 361 located on the back side of the pedal base 35; the pressure plate 361 has a vertical limiting function, and the fixing bolts cooperate with the guide slot 352 to limit the left and right movement.

[0067] In addition, in order to facilitate sliding between the sliding plate 36 and the pedal base 35, a plurality of longitudinally extending semi-cylindrical grooves are provided on the upper end of the pedal base 35, and rollers 353 are installed in the semi-cylindrical grooves. The plurality of rollers 353 are distributed along a transverse array.

[0068] like Figure 8 As shown, a pair of reset mechanisms are provided between the sliding plate 36 and the pedal base 35. These reset mechanisms include a sliding shaft 354, a reset spring 355, and a stopper 365. The reset spring 355 is sleeved on the sliding shaft 354 and mounted within a guide groove of the pedal base 35. The stopper 365 is provided on the back of the sliding plate 36 and engages with a protrusion on the upper end of the sliding shaft 354 to achieve a reset effect. The pair of reset mechanisms are provided on the upper and lower sides of the guide slider 364 and are symmetrically distributed about the center.

[0069] When the yacht completes the turn and resumes straight-line travel, one of the reset mechanisms starts working, and the sliding shaft 354 moves outward under the pressure of the reset spring 355. The sliding shaft 354 drives the sliding plate 36 to return to its initial position through the limiting protrusion 365. At this time, the positioning ball 351 cooperates with the positioning blind hole 362 in the middle position on the sliding plate 36.

[0070] like Figure 7 As shown, in order to enhance the friction force of the upper end of the sliding plate 36, an anti-slip pad 31 is installed on the upper end of the sliding plate 36. A large number of small protrusions are provided on the anti-slip pad 31, and stoppers are respectively provided on the left front and right front of the anti-slip pad 31.

[0071] It should be noted that different structures can also be used to achieve left and right sliding between the sliding plate 36 and the pedal base 35. The sliding guide mechanism can be composed of a slider and a linear guide rail; the roller that plays a sliding role can also be replaced by a ball bearing; the reset mechanism composed of the limiting protrusion 365, the sliding shaft 354, and the reset spring 355 can also be replaced by other mechanisms, such as elastic ropes, tension springs, etc.

[0072] like Figure 12 As shown, based on the above-mentioned foldable foot control device, the present invention also proposes a control method for the foldable foot control device, comprising the following steps:

[0073] S1: The upper rocker arm is driven to rotate a certain angle by controlling the pedal mechanism to move downward; under the action of the timing belt, the lower rocker arm rotates synchronously with the rotation of the upper rocker arm and rotates the same angle in the opposite direction;

[0074] S2: A circular magnet on one side of the lower end of the lower rocker arm rotates with it and determines the rotation angle through an angle sensing chip. The angle sensing chip outputs acceleration and deceleration signals corresponding to the rotation angle to the actuator through a data line.

[0075] S3: By controlling the sliding plate containing the induction magnet to move left or right; one of the Hall switches installed on the pedal base faces the induction magnet and obtains a magnetic signal;

[0076] S4: The steering control circuit board receives the electromagnetic signal input by the Hall switch and determines the steering gear position; the circuit board inputs an electrical signal to the actuator through the data line, and the actuator controls the steering of the device.

[0077] The control method of the present invention uses a synchronous belt to make the lower rocker arm and the upper rocker arm rotate synchronously in opposite directions at the same angle, and then through the cooperation of a circular magnet and an angle sensing chip, the angle sensing chip can determine the rotation angle of the lower rocker arm and output a control signal to the acceleration and deceleration actuator; by arranging an induction magnet on the sliding plate and a plurality of Hall switches on the pedal base, the two can cooperate to achieve multi-level steering in the direction of action; and the foot control pedal can realize steering operation based on the original acceleration and deceleration.

[0078] In one embodiment, the control method of the foldable foot control device provided by the present invention further includes the following steps:

[0079] S5: By controlling the pedal base to rotate around the pin, the key trigger plate double-clicks the key ring on the back of the steering control circuit board, and the steering control circuit board generates a reverse signal;

[0080] S6: By controlling the pedal base to rotate around the pin shaft, the key trigger plate clicks the key ring, and the steering control circuit board generates a forward signal;

[0081] S7: By controlling the pedal base to rotate around the pin shaft to a horizontal state, the key trigger plate and the key ring are kept in contact for more than 3 seconds, and the steering control circuit board generates a shutdown signal.

[0082] The control method of the present invention improves the function of the foldable foot control device by setting a key trigger plate and a key ring on the back of the steering control circuit board, and allowing the number of clicks of the key trigger plate to be different, so that the steering control circuit board produces different signals such as forward, reverse, and shutdown.

[0083] The working principle and working process of the foldable foot control device of the present invention will be briefly described below with reference to the accompanying drawings.

[0084] First, the side cover plug assembly 4 is installed on the side of the control box body 1 by screws, so that the multiple spring pins 25 are in contact with the multiple spring pin contact points 432 respectively to achieve electrical connection; at the same time, the position of the angle sensing chip 431 is opposite to the circular magnet 26; in addition, the outer end of the fixed socket 41 can be detachably connected to the plug that matches it.

[0085] Secondly, the buckle movable locking mechanism 11 provided on the upper end of the control box body 1 is toggled to disengage the limit buckle 33 from the movable locking mechanism 11, and the lifting mechanism 2 automatically pops open under the drive of the reset torsion spring 215 and the synchronous belt.

[0086] Then, the user controls the pedal base in the foot pedal mechanism 3 to rotate, and the key ring 383 rotates with the pedal base and contacts the key trigger plate 32 once or multiple times, causing the steering circuit board assembly 38 to generate forward and reverse signals, and transmit the forward and reverse signals to the actuator through the spring pin 25, the spring pin contact point 432, the socket circuit board 43 and the fixed socket 41.

[0087] Then, the user controls the pedal mechanism 3 to move downward and drives the upper rocker arm 22 to rotate a certain angle. When the upper rocker arm 22 rotates a certain angle counterclockwise, due to the presence of the synchronous belt 211, the lower rocker arm 21 rotates the same angle clockwise relative to the lower step shaft 212.

[0088] When the lower rocker arm 21 drives the circular magnet 26 to rotate, the angle sensing chip 431 can accurately detect the rotation angle of the circular magnet 26, and then determine the rotation angle of the lower rocker arm 21 and the upper rocker arm 22, and then determine the magnitude of the force applied by the user to the pedal mechanism 3, and finally input the electromagnetic signal of the angle sensing chip 431 to the acceleration and deceleration actuator to control the acceleration and deceleration of the entire yacht.

[0089] When the yacht needs to turn left or right, the user presses one foot on the anti-slip pad 31 and applies force to the left or right. The sliding plate 36 moves with the anti-slip pad 31 and drives the guide slider 364 along the guide rod 356, simultaneously driving the induction magnet 363 to move to one of several Hall switches facing the induction magnet and obtaining a magnetic signal. The circuit board receives the electromagnetic signal input by the Hall switch and determines the steering position. The circuit board inputs an electrical signal to the actuator via a data line, and the actuator controls the device's steering. Specifically, when the sliding plate 36 moves a small distance, the induction magnet 363 moves to the first steering position adjacent to the straight line. When the sliding plate 36 moves a large distance, the induction magnet 363 moves to the second steering position or more steering positions.

[0090] Finally, when reaching the designated position or docking, the user controls the foot pedal mechanism 3 to be horizontal and makes the button ring 383 contact with the button trigger plate 32 for a long time to complete the shutdown action; the user continues to press the foot pedal mechanism 3 vertically downward until the limit buckle 33 is fully engaged with the movable locking mechanism 11 to realize the folding of the foot control device.

[0091] The foldable foot control device provided by the present invention uses a common encoder, a magnetic encoder or a Hall sensor as a signal generating device; the foldable structural design makes the device compact, safe and reliable, and can realize the functions of acceleration and deceleration; the device can be stored in the main body box when not in use; when in use, the dial key is pressed and the device can automatically pop out for use; the device is small in size and light in weight, and important electrical components are all waterproof and sealed, and the wiring is connected using a waterproof aviation plug, making it safe, convenient and reliable to use.

[0092] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
