Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] The core of the present invention is to provide a paddling device and a propeller thereof, which can improve the endurance of the propeller.

[0059] For a specific embodiment of the propeller of the paddling equipment provided by the present invention, please refer to Figures 1 to 3 , including a power propulsion module 31 and a power battery 324.

[0062] The power battery 324 of the thruster in this embodiment is detachable, so that the power battery 324 can be quickly replaced to increase the battery life and improve the user experience without stopping to wait for charging.

[0063] Furthermore, if Figure 1 and Figure 2As shown, the thruster further includes a battery housing 325, a battery compartment 322 having an opening is formed in the battery housing 325, a power battery 324 is built in and detachably connected to the battery compartment 322; the power propulsion module 31 is detachably fixedly connected to the battery housing 325 and covers the opening of the battery compartment 322; the power battery 324 can be installed and removed from the battery compartment 322 through the opening of the battery compartment 322. At this time, the battery housing 325 and the power battery 324 constitute the power battery module 32, and the thruster as a whole is divided into two major parts: the power propulsion module 31 and the power battery module 32.

[0064] Among them, Figure 2 As shown, the battery compartment 322 is a compartment body that can completely wrap the power battery 324, and the power propulsion module 31 provides a flat sealing cover to seal the opening of the battery compartment 322. In other embodiments, the battery compartment 322 can also half wrap the power battery 324, and the remaining part of the power battery 324 is wrapped by the power propulsion module 31.

[0065] The battery housing 325 of the thruster in this embodiment is detachable, so that the battery housing 325 and the power battery 324 therein can be removed as a whole to separate them from other parts of the thruster, allowing the power battery 324 to be replaced more quickly.

At this time, the controller 314 is exposed to the propeller, as a part of the propeller housing, which is conducive to miniaturization of the propeller.

[0067] Furthermore, if Figure 2 As shown, the propulsion structure includes a propulsion blade 312, specifically a propeller, and a fairing 311, the driver is connected to the propulsion blade 312, the fairing 311 is set outside the propulsion blade 312, and the fairing 311 is fixed to one end of the main housing 33, which has a simple structure and is easy to assemble. Among them, the driver 313 can be a brushless motor 3131.

[0068] Furthermore, a connection lock 323 is provided on the battery housing 325, and the connection lock 323 can detachably fix the battery housing 325 to the power propulsion module 31. The connection lock 323 includes an elastic buckle, which can be self-locked to a hook or a slot on the power propulsion module 31 by elasticity, and in other embodiments, it can also be opened by elasticity. This connection lock 323 is quick and convenient to use and has high stability. In addition, a plurality of connection locks 323 can be provided to maintain the stability and reliability of the connection; alternatively, the battery housing 325 and the power propulsion module 31 or the battery housing 325 and the main housing 33 can also be detachably fixed by other means such as snap connection and threaded connection.

[0069] Furthermore, a paddle board mounting plate 321 is fixedly disposed outside the battery compartment 322 for connecting to the paddle board 2 .

[0070] In another specific embodiment, the propeller can be configured as other structures, such as Figures 4 to 8 The second embodiment shown also includes a power propulsion module 31 and a power battery 324. In this case, the power battery 324 is detachably fixed to the main housing 33. Specifically, the main housing 33 is integrally formed with a battery compartment 322, the opening of which is provided on the main housing 33, and the opening of the battery compartment 322 is detachably fixedly connected to the first sealing cover plate 334, and the power battery 324 can be installed and removed from the battery compartment 322 through the opening of the battery compartment 322.

At this time, two propulsion bodies formed by the propulsion structure connected to the driver 313 are set, respectively located in the two first installation cavities 337 of the main shell 33, and the two propulsion bodies are respectively electrically connected to the controller 314 in the second installation cavity 338 of the main shell 33. Among them, the two battery compartments 322 are respectively located between the second installation cavity 338 and the two first installation cavities 337, and accordingly, the two power batteries 324 are respectively located between the controller 314 and the two propulsion bodies to ensure the symmetry and stability of the structure. Among them, a connector 3241 is set on the power battery 324, and an O-ring 3242 is set on the outer ring of the connector 3241, and the controller 314 is electrically connected through the connector 3241.

[0072] Furthermore, a wireless module 34 is also provided on the main housing 33, so that the controller 314 can communicate wirelessly with other external devices, and can be specifically provided in the second installation cavity 338. In addition, a quick-off button 333 is also provided on the main housing 33, so as to timely open and close the propeller 3. When in use, after the paddle board 2 is inflated, the paddle board tail fin 22 is manually pushed into the paddle board mounting clamp 331 of the propeller 3 to clamp and fix it, and the installation is completed; the quick-off button 333 is turned on to start the propeller 3.

[0073] Furthermore, in order to further increase the freedom of charging, a charging port 332 is also provided on the main shell 33 so as to directly charge the power battery 324 when it is installed in the battery compartment 322 .

[0074] Furthermore, a paddle board mounting clip 331 is also provided on the main housing 33, which can be a groove formed between the two first mounting cavities 337 to sleeve and clamp the paddle board tail fin 22 on the paddle board 2 to achieve the assembly of the propeller 3 and the paddle board 2. This paddle board mounting clip 331 is compatible with the paddle board tail fin 22 used.

[0075] Alternatively, in the specific embodiment 3, if Fig. 9 As shown, compared with the second embodiment, it is also a structure with a power propulsion module 31 and two power batteries 324. At this time, the power battery 324 is detachably fixed to the main shell 33. Specifically, the main shell 33 is integrally formed with two battery compartments 322, and the openings of the two battery compartments 322 are respectively opened on the main shell 33. However, in the second embodiment, the opening is located at the top or bottom of the main shell 33, while in this embodiment, the opening is located at the rear side of the main shell 33. The opening of each battery compartment 322 is detachably fixedly connected to the first sealing cover plate 334, and the power battery 324 can be installed and removed from the battery compartment 322 through the opening of the battery compartment 322. At this time, the power battery 324 is installed from the top or bottom of the main shell 33 in the second embodiment, and the power battery 324 is installed from the rear side of the main shell 33 in this embodiment.

[0076] Further, in the power propulsion module 31, it includes a driver 313, a propulsion structure and a controller 314, the propulsion structure is connected to the main shell 33, the propulsion structure is connected to the driver 313, and the controller 314 is electrically connected to the driver 313. The driver 313 is specifically a waterproof motor. At this time, a propulsion body formed by the propulsion structure connected to the driver 313 is set, which is respectively located in a first installation cavity 337 of the main shell 33, and the propulsion body is electrically connected to the controller 314 in the second installation cavity 338 of the main shell 33. Among them, the two battery compartments 322 are respectively located between the second installation cavity 338 and the first installation cavity 337. Specifically, the first installation cavity 337, the battery compartment 322, and the second installation cavity 338 are arranged in sequence from front to back. Correspondingly, the two power batteries 324 are respectively located between the controller 314 and the propulsion body to ensure the symmetry and stability of the structure.

[0077] Furthermore, a wireless module 34 is also provided on the main housing 33, which can be specifically an antenna, so that the controller 314 can communicate wirelessly with other external devices, and the wireless module 34 and the controller 314 can be respectively located in front of the two power batteries 324 to ensure structural symmetry. In addition, a quick-off button 333 is also provided on the main housing 33, which can also be called a power switch, to turn on and off the thruster 3 in time.

[0078] Furthermore, a clamping handle 339 is also provided on the main shell 33, which can be installed between the two power batteries to be connected to the paddle board 2, so as to realize the assembly of the propeller 3 and the paddle board 2, which is convenient to assemble and has good compatibility.

[0079] On the basis of the above-mentioned embodiments, in order to facilitate the inflation and deflation of the paddle board 2, the main housing 33 is also connected to an air pump 36 and / or an air extraction pump 35 to inflate and / or exhaust the paddle board 2. When using the paddle board 2, the air pump 36 on the main housing 33 is first connected to the paddle board inflation hole 21 on the paddle board 2 to inflate the paddle board 2, and then the propeller 3 and the lowering board 2 are connected; after using the paddle board 2, the propeller 3 can be removed from the paddle board 2, and then the air extraction pump 35 is used to exhaust air through the paddle board inflation hole 21 on the paddle board 2 (specifically located on the top of the paddle board 2). At this time, since the propeller 3 is directly equipped with the air pump 36 and / or the air extraction pump 35, the use of the paddle board 2 can be facilitated.

[0080] Specifically, the air pump 36 and the air extraction pump 35 are respectively built into the two first installation cavities 337, and can be specifically located between the two propulsion bodies and the two power batteries 324. The main shell 33 is provided with an interface 336 connected to the first installation cavity 337, and the interface 336 is detachably fixedly connected to the second sealing cover 335. At this time, when charging and deflating, the second sealing cover 335 can be opened, and the air pump 36 and the air extraction pump 35 are not removed from the main shell 33. The pipeline is directly connected to the air pump 36 or the air extraction pump 35 through the interface to connect the paddle board 2.

[0081] Alternatively, the air pump 36 and the air pump 35 can be detachably connected to the main shell 33. When inflating or deflation, the air pump 36 and the air pump 35 can be removed from the main shell 33 to perform the inflation or deflation operation, and then put back into the main shell 33 after the operation.

[0082] In particular, when the propeller in the first embodiment is provided with an air pump 36 and an air extraction pump 35, a connection structure may be provided on the main housing 33, the driver 313, or the battery housing 325 to connect the air pump 36 and the air extraction pump 35, or only one of the two may be provided. For example, a first installation cavity may be added to the side of the main housing 33 to install the air pump 36.

[0083] In addition to the above-mentioned propeller, the present invention also provides a paddling equipment, which includes a propeller. The propeller can specifically be the propeller provided in any of the above embodiments, and the beneficial effects can be correspondingly referred to the above embodiments.

[0084] like Figures 11 to 13 As shown, the paddling equipment includes a paddle 1 and a paddle board 2, a propeller 3 is provided on the paddle board 2, and a paddling sensor is provided on the paddle 1 to detect whether the paddle is performing a paddling action. Fig.11 As shown, the rowing 1 is composed of a blade, a paddle shaft and a handshake in sequence along a set axial direction. The paddle shaft includes a blade paddle shaft 113, an intermediate paddle shaft 123 and a handshake paddle shaft 131 connected in sequence along the axial direction.

[0085] like Fig.11 As shown, a central processor is arranged on the paddle 1, and the propeller 3 and the paddle sensor are respectively connected to the central processor in communication. Specifically, the propeller 3 is connected to the central processor via wireless signal communication, and the paddle sensor is connected to the central processor via wire communication.

[0086] The rowing equipment has a resistance mode. If the rowing equipment is in assist mode:

[0087] When the paddling sensor detects that the paddling 1 is performing a paddling action, the central processor controls the propeller 3 to provide thrust according to a preset rule;

[0088] When the paddling sensor detects that the paddling action of the paddle 1 stops, the central processing unit controls the propeller 3 to stop providing thrust.

[0089] like Fig.11 and Fig.12 As shown, in the axial direction, the rowing 1 may specifically include: a blade module 11, a paddle shaft intermediate module 12 and a central control module 13, and the blade module 11 and the central control module 13 are respectively located at two ends of the paddle shaft intermediate module 12.

[0090] The blade module 11 includes a blade 111, a paddling sensor, and a blade propeller 113. A sensor amplifier is integrated in the control board 136. The blade propeller 113 is connected to the blade 111, and the blade propeller 113 is a blade rod.

[0091] The paddling sensor is a strain sensor 112, which is specifically arranged on the central axis of the blade 111 and close to the edge of the blade 111. When the water flows through the strain sensor 112, the strain sensor 112 will be deformed. By detecting the deformation, it is determined whether the paddling action is performed. Alternatively, the paddling sensor can also be a torque sensor arranged at the joint of the blade 111, or a pressure sensor arranged on the water-facing surface of the blade 111, which detects the corresponding force value to determine whether the paddling action is performed.

[0092] The propeller intermediate module 12 includes a lock 121, a spiral connection line 122 and an intermediate propeller 123. The lock 121 connects the intermediate propeller 123 to the blade propeller 113, and can be detachably connected. The intermediate propeller 123 and the blade propeller 113 can be sealed by a watertight connector; the spiral connection line 122 is built into the intermediate propeller 123 to electrically connect the sensor amplifier 114 and the central processor. At the same time, since the spiral connection can be stretched, it is convenient to adapt to the length of the propeller.

[0093] The central control module 13 includes a handshake paddle 131, a paddling battery 132, a handshake 133, a mode switching structure 134, a gear adjustment structure 135, a control panel 136, a POGO PIN charging interface 137, a paddle power indicator 138, and a signal transmitting antenna 139. Fig.11 and Fig.12 As shown, the handshake paddle rod 131 and the paddle blade paddle rod 113 are respectively connected to the two ends of the middle paddle rod 123, and the handshake 133 is fixed to the other end of the handshake paddle rod 131. The handshake paddle rod 131 is a handle paddle rod, and the handshake 133 is specifically an anti-slip handshake; the paddling battery 132 is built into the handshake paddle rod 131; the mode switching structure 134, the gear adjustment structure 135, the control panel 136, the POGO PIN charging interface 137, the paddle power display light 138, and the signal transmitting antenna 139 are all arranged on the handshake 133 or in the handshake 133 for easy control.

[0094] The mode switching structure 134 is connected to the central processor in communication, and is specifically a button, and may also be a knob in other embodiments. By triggering the mode switching structure 134, the operation mode of the paddling equipment can be switched to the power mode or the automatic mode, and the central processor then operates and controls the propeller 3 according to the mode selected by the mode switching structure 134. The mode switching structure 134 has an RGB light to display the power level of the propeller 3.

[0095] Among them, the gear adjustment structure 135 is connected to the central processor in communication, specifically a knob, and can also be a button in other embodiments. The gear adjustment structure 135 can adjust the preset limit thrust provided by the propeller 3 in each operating mode. In addition, the gear adjustment structure 135 can also be used to control the start and stop of the paddling equipment, specifically to control the start and stop of the propeller. In the stopped state, by adjusting the gear adjustment structure 135 to any gear, the paddling equipment is started, and when it is adjusted to the 0 gear, the paddling equipment is stopped. Accordingly, the propeller 3 reduces the thrust to stop, and there is no need to set a separate switch.

[0096] The control board 136 integrates hardware such as a central processing unit and a buzzer. The control board 136 is built into the handshake 133 .

[0097] Among them, the POGO PIN charging interface 137 includes buttons, knobs, a control panel 136, interfaces and other hardware. These hardware are waterproofly packaged as a component in the hole of the handshake 133. Specifically, on the handshake 133, a mode switching structure 134 and a gear adjustment structure 135 are set at one end perpendicular to the axial direction, and a POGO PIN charging interface 137 and a paddle power display light 138 are set at the other end.

[0098] Based on the setting of the strain sensor 112, when the player controls the paddle 1 to perform a paddling action, the paddle 111 pushes the water to generate a water flow. The generated water flow passes through the strain sensor 112, causing the strain sensor 112 to deform and change its resistance. The resistance signal is amplified by the sensor amplifier 114, and the signal is transmitted to the central processor in the handshake 133 through the spiral connecting line 122. After the central processor processes the signal, the signal transmitting antenna 139 sends the signal (specifically, it can be a 433MHz frequency band) to the propeller 3, specifically to the control unit of the propeller 3. The propeller 3 performs corresponding actions according to the received signal.

[0099] In this embodiment, the paddle 1 is used as the wireless control part, and the propeller 3 is used as the execution part. The two are used together to achieve the effect of assisting the paddle board 2 to move forward, and the propeller 3 pushes the paddle board 2 and the paddle 1 action to have high synchronization and consistency. When the paddle 1 is paddling, the propeller 3 provides assistance to save the user's effort, and after the paddle 1 stops paddling, the propeller 3 also stops providing assistance accordingly, which can retain the fun of the original paddling equipment. In addition, the control unit of the paddle 1 is integrated in the part of the handshake 133 for easy operation. In addition, the components on the paddling equipment can be waterproofed as needed.

[0100] A specific working process of the paddling equipment of the present invention includes:

[0101] 1. Switch control:

[0102] Turn on the machine—the gear adjustment structure 135 is rotated to any gear position to turn on the machine;

[0103] Shutdown—The gear adjustment structure 135 rotates to gear 0 to shut down the machine.

[0104] 2. Power-Assist Mode (the mode switching structure 134 remains in the power-assist position):

[0105] First gear power assist—the gear adjustment structure 135 is rotated to the first gear;

[0106] Second gear power assist - gear adjustment structure 135 is rotated to 2nd gear;

[0107] Third gear power assistance—the gear adjustment structure 135 is rotated to the third gear.

[0108] 3. Automatic mode (the mode switching structure 134 remains in the automatic position):

[0109] First gear automatic—the gear adjustment structure 135 is rotated to first gear;

[0110] Second gear automatic—the gear adjustment structure 135 is rotated to the second gear;

[0111] Three-speed automatic—the gear adjustment structure 135 is rotated to the 3rd gear.

[0112] 4. Switch between power-assisted mode and automatic mode (press mode switch structure 134 to switch):

[0113] Static state of the paddle board - the paddling action of paddle 1 triggers propeller 3, and the power of propeller 3 increases smoothly;

[0114] Paddle board dynamic state - propeller 3 continues to propel paddle board 2 at the current gear position.

[0115] 5. Switch between automatic mode and power-assisted mode (press mode switch structure 134 to switch):

[0116] Static state of the paddle board - the paddling action of paddle 1 triggers propeller 3, and the power of propeller 3 increases smoothly;

[0117] Paddle board dynamic state - propeller 3 assists paddle board 2 to move forward in the current gear position.

[0118] The paddling equipment in the present invention has a selectable operating mode, which retains the fun of the existing paddle board and adds the concept of electric power assistance. The player only needs to control the control part on the handshake or directly control the propeller 3 with the help of the paddling action. There is no need to add an additional remote control to control the propeller 3. In the power-assisted mode, the propeller 3 is automatically controlled according to the paddling action of the paddle 1, achieving the state of unity between man and paddle.

[0119] In addition, the rowing assembly can be controlled according to the following control method, including the following steps:

[0120] If the paddling equipment is in power-assisted mode:

[0121] S11: When the paddle 1 performs a paddling action, the propeller 3 is controlled to provide thrust according to a preset rule.

[0122] Among them, from the time when the paddling equipment enters the power-assist mode to before the first paddling action is performed, the propeller 3 does not provide thrust.

[0123] Among them, when the set parameters of paddling 1 (such as deformation, speed) reach (≥) the set paddling standard, it is regarded as paddling action, otherwise, it is regarded as no paddling action. It should be noted that according to the duration of no paddling action, it can be divided into pausing paddling action (for example, ≤ the first preset duration) and stopping paddling action (for example, > the first preset duration).

[0124] S12: When the paddling action of the paddle 1 stops, the propeller 3 is controlled to stop providing thrust.

[0125] The process of the propeller 3 stopping providing thrust usually includes a thrust reduction process until the thrust is reduced to 0.

[0126] Among them, during the thrust reduction process when the propeller 3 stops providing thrust, if the paddling 1 performs the paddling action again, the thrust reduction can be stopped and S11 can be entered again, or the thrust reduction process of the propeller 3 can be continued, and after it is reduced to 0, the propeller 3 can be controlled according to the action after the paddling 1.

[0127] In this embodiment, due to the power-assist mode, the propulsion of the paddle board 2 by the propeller 3 and the paddling action 1 are more synchronized and consistent. When paddling 1 is paddling, the propeller 3 provides power assistance to save the user's effort. After paddling 1 stops paddling, the propeller 3 will not continue to provide thrust all the time, but will stop providing power assistance in time, thereby retaining the fun of the original paddling equipment.

[0128] Further, regarding the duration for which the propeller 3 provides thrust, in S11: controlling the propeller 3 to provide thrust according to preset rules, specifically including: from the time when the paddling 1 starts to perform the paddling action to the time when the paddling 1 does not perform the paddling action for a first preset time period, controlling the propeller 3 to continue to provide thrust.

[0129] In this embodiment, the first preset time length is specifically 3 seconds. Of course, in other embodiments, the first preset time length may also be 2 seconds, 5 seconds, etc.

[0130] When the paddling 1 does not perform the paddling action within a first preset time period, it is determined that the paddling 1 starts to stop the paddling action.

[0131] by Fig.13Taking the solid line I in the figure as an example, from point O to point A, the paddling action is continuously performed, or the duration of not performing the paddling action is no more than the first preset duration (for example, not performing the paddling action for 2s). Therefore, during this period, the thruster 3 continues to provide thrust, and the duration from point A to point B is the first preset duration, i.e., 3s. No paddling action is performed during this period, and there is still no paddling action at point B. Then, starting from point B, it can be determined that the paddling action 1 starts to stop, and the process can enter S12.

[0132] This embodiment limits the time to stop providing thrust, which can avoid the propeller 3 from shutting down when the paddling 1 does not perform paddling action for a very short period of time, thereby reducing the start and stop frequency of the propeller 3.

[0133] Of course, in other embodiments, it can also be set that the propeller 3 continues to provide thrust within a second preset time period starting from the time 0 when it is determined that the paddling 1 is performing a paddling action, and then enters S11 after the second preset time period.

[0134] Further, regarding the magnitude of the thrust provided by the propeller 3, in S11, in the process of controlling the propeller 3 to continuously provide thrust, specifically including: if the thrust provided by the propeller 3 is less than the preset limit thrust, then controlling the thrust provided by the propeller 3 to continuously increase; otherwise, controlling the thrust provided by the propeller 3 to remain unchanged.

[0135] In this embodiment, the maximum thrust of the thrust provided by the thruster 3 is limited, which can further improve the controllability of the use effect. Fig.13 Between point O and point C on the solid line I in FIG, the thrust provided by the thruster 3 increases continuously. When the preset limit thrust is reached, that is, Fig.13 After the moment of point C on the solid line I in FIG. 1 , the thruster 3 is maintained at the preset limit thrust.

[0136] Further, regarding the setting of the preset limit thrust of the thruster 3, the preset limit thrust may specifically include a plurality of thrusts of different gears that can be selected. Specifically, the preset limit thrust may have three gears, for example, 1 m / s (corresponding to Fig.13 The first gear thrust of the solid line I), 1.5m / s (corresponding to Fig.13 The second gear thrust of the solid line II), 2m / s (corresponding to Fig.13 In other embodiments, the number of gears and the thrust value of each gear may also be set to other values, such as five gears. Since each gear is equivalent to limiting the maximum thrust, when a gear is selected, the thruster 3 has a maximum thrust of the preset limit thrust corresponding to the gear as the maximum thrust.

[0137] Based on the setting of the gear position, S11: when the paddle 1 performs a paddling action, before controlling the propeller 3 to provide thrust according to a preset rule, the control method further includes:

[0138] S01: Obtain the preset limit thrust.

[0139] By setting multiple gears of preset extreme thrust for acquisition, the flexibility of using the paddling equipment can be further improved.

[0140] Further, regarding the setting of the rate of increase of the thrust provided by the propeller 3 , it can be a variable, which is specifically associated with the set parameters of the rowing 1 .

[0141] Among them, Fig.11 As shown, a strain sensor 112 is provided on the paddle 1. When the deformation amount of the strain sensor 112 reaches (≥) a preset standard, it is determined that the paddle 1 performs a paddling action. The strain sensor 112 is used as a paddling sensor to judge the paddling action, and the judgment sensitivity is good. Correspondingly, the paddling 1 does not perform a paddling action according to the detection of the strain sensor 112. When its deformation amount does not meet the preset standard, the paddling action is not performed.

[0142] Among them, in S11: controlling the thrust provided by the thruster 3 to continuously increase includes:

[0143] The increasing rate of the thrust provided by the propeller 3 is controlled according to the deformation amount of the strain sensor 112 .

[0144] The deformation magnitude of the strain sensor 112 is positively correlated with the increasing rate of the thrust provided by the thruster 3 .

[0145] That is to say, when the deformation amount of the strain sensor 112 reaches the preset standard: the larger the deformation amount, the greater the rate of increase of the thrust; the smaller the deformation amount, the smaller the rate of increase of the thrust.

[0146] by Fig.13 For example, for the dotted line I and the solid line I, the preset limit thrust is the same. In the stage of thrust increase, when the deformation of the strain sensor 112 is 10, the thrust increase rate is 2, and the thrust change of the thruster 3 corresponds to the portion from point O to point C of the solid line I, and the thrust increase rate corresponds to the slope d of this portion of the solid line I; when the deformation of the strain sensor 112 is 20, the thrust increase rate is 5, and the thrust change of the thruster 3 corresponds to the portion from point O to point D of the dotted line I', and the thrust increase rate corresponds to the slope d' of this portion of the dotted line I', and d' is greater than d.

[0147] Additionally, in actual use, the rate at which thrust increases may be variable.

[0148] Furthermore, the control method further includes:

[0149] S02: Obtain the operation mode of the paddling equipment.

[0150] The operating modes include power-assisted mode and automatic mode, wherein the automatic mode can also be referred to as pure electric mode.

[0151] If the paddling equipment is in automatic mode:

[0152] S2: Control the thruster 3 to continuously provide thrust.

[0153] Among them, in S2, specifically including:

[0154] S21: When the paddling 1 starts to perform the paddling action for the first time, the propeller 3 is controlled to provide continuous thrust.

[0155] Among them, in S22, while controlling the propeller 3 to continuously provide thrust, the thrust will continue to increase and reach the corresponding preset limit thrust, and in this mode, after the propeller 3 starts to provide thrust, it is no longer controlled by the paddling action 1. At this time, even if the paddling 1 does not paddling or stops paddling, the paddle board 2 still moves automatically under the push of the propeller 3, and both hands can be freed.

[0156] Of course, in other embodiments, in S22, the propeller 3 may be controlled to provide continuous thrust at the moment of entering the automatic mode.

[0157] Among them, the power-assisted mode and the automatic mode can share the same gear, that is, when in the same gear, the preset limit thrust is the same.

[0158] When in automatic mode, after the propeller 3 is started, the propeller 3 first increases the thrust until the preset limit thrust corresponding to the selected gear, and then runs at the preset limit thrust. At this time, the start or stop of the propeller 3 has nothing to do with the action of paddling 1, and the degree of automation is relatively high.

[0159] When in the power-assist mode, the propeller 3 starts or stops according to the action of paddling 1, but the thrust of the propeller 3 reaches the preset limit thrust corresponding to the selected gear, such as Fig.13 As shown, 3s is used as the first preset duration, which may specifically include three stages:

[0160] Speed-up phase: Each time the paddle 1 strokes, the thrust of the propeller 3 will increase by a certain amount, which will last for 3 seconds. If the paddle 1 continues to stroke within 3 seconds, the thrust will continue to increase.

[0161] Extreme speed stage: It takes about 5 strokes in each gear to reach the extreme speed state (that is, the thrust reaches the preset limit thrust). If you want to maintain the current extreme speed state, you must continue to stroke within 3 seconds.

[0162] Deceleration phase: after the paddle 1 stops paddling for 3 seconds, the propeller 3 continues to reduce the thrust within 1.5 seconds until it stops working.

[0163] Among them, after the paddling equipment is switched from the power-assisted mode to the automatic mode, if the propeller 3 is not currently started, the propeller 3 can be started when the paddling 1 starts the paddling action for the first time, and then it is no longer controlled by the paddling 1; if the propeller 3 is currently started, it continues to provide thrust to the paddle board 2 with the current corresponding gear.

[0164] Among them, after the paddling equipment is switched from the automatic mode to the power-assisted mode, it continues to be controlled according to the control method of the propeller 3 in the power-assisted mode.

[0165] Of course, the structures on the central control module 13 can be assembled or arranged in other ways. Figures 16 to 19 In the third embodiment shown, the central control module 13 includes a rowing battery 132, a handshake 133, a mode switching structure 134, a gear adjustment structure 135, a control panel 136, a rowing power indicator 138 (including a rowing power indicator 1311 and a propeller power indicator 1312), a signal transmitting antenna 139 (such as a 2.4G antenna), and a switch indicator 1313. The control panel 136 can communicate with the corresponding propeller 3 via a wireless module such as Bluetooth.

[0166] Among them, the mode switching structure 134, the gear adjustment structure 135, the control panel 136, the paddling power display light 1311, the propeller power display light 1312, the switch indicator light 1313, and the signal transmitting antenna 139 are all arranged on the handshake 133 for easy operation.

[0167] The mode switching structure 134 is connected to the central processing unit in communication, and is specifically a button. By triggering (pressing) the mode switching structure 134, the operation mode of the paddling equipment can be switched to the power-assisted mode or the automatic mode, and the central processing unit then operates and controls the propeller 3 according to the mode selected by the mode switching structure 134. A switch indicator light 1313 is set in the middle of the mode switching structure 134, which displays the mode of the propeller 3 by switching colors or flashing states. For example, a green light is long on for the power-assisted mode, and a blue light is long on for the automatic mode.

[0168] In addition, the mode switching structure 134 can also be used to control the on / off of the paddling and the activation of the Bluetooth module on the control panel 136. Specifically, by short-pressing (<2 seconds each time) the mode switching structure 134, the paddling can be turned on and off. After turning on, it can automatically enter the Bluetooth pairing connection state, which is indicated by the flashing of the switch indicator light 1313. After the set time, the switch indicator light 1313 stops flashing, and the Bluetooth pairing connection ends. By long-pressing the mode switching structure 134 (≥2 seconds each time), the power-assisted mode and the automatic mode are switched.

[0169] The gear adjustment structure 135 is connected to the central processor in communication, and is specifically a knob. The gear adjustment structure 135 can adjust the preset limit thrust provided by the propeller 3 in each operation mode.

[0170] Among them, on the handshake 133, a mode switching structure 134 and a gear adjustment structure 135 are set at one end perpendicular to the axis, and a paddling charging port 1310 and a paddle power display light 138 are set at the other end. The paddling charging port 1310 can be connected to a power source to charge the paddling battery 132, or the paddling battery 132 can also be charged by wireless charging.

[0171] In addition, the paddle power display light 138 includes a rowing power display light 1311 and a propeller power display light 1312, which respectively indicate the rowing power (specifically the power of the rowing battery 132) and the propeller power (specifically the power of the power battery in the propeller), so that the user can charge or replace the battery in time.

[0172] During use, depending on the remaining battery level, the paddling power indicator light 1311 and the propeller power indicator light 1312 may display different colors or flash and stay on to indicate the remaining power level.

[0173] In another specific embodiment, the paddling sensor may also be configured in other ways. Fig.14 and Fig.15 In the embodiment shown, the paddling sensor is arranged on the paddle rod, and the force applied to the paddle blade 111 during paddling can be transmitted to the paddle rod. Therefore, by detecting the force applied to the paddle rod, it can be determined whether the paddling of the paddle blade 111 is paddling. Specifically, the paddling sensor is a strain sensor 112, and is arranged on a handshake paddle rod 131 near the handshake 133. In addition, the paddle rod also includes the paddle blade paddle rod 113, the middle paddle rod 123, and the handshake paddle rod 131 in the above embodiment.

[0174] Alternatively, in Embodiment 3, if Figures 16 to 19 As shown, the paddling sensor may also include a water contact sensor 115 and a strain sensor 112 to ensure that the paddling 1 is judged as a paddling action when the paddling 1 is in the water contact state.

[0175] Specifically, a water contact sensor 115 and a strain sensor 112 are provided on the paddle 1. When the water contact sensor detects liquid and the deformation of the strain sensor 112 reaches a preset standard, it is determined that the paddle 1 performs a paddling action. At this time, other control methods based on the strain sensor 112 can refer to the above embodiments, which will not be repeated here.

[0176] The water contact sensor 115 is disposed on the paddle blade 111 , specifically at an end away from the paddle rod, and the strain sensor 112 is disposed on the paddle rod, specifically at an end close to the paddle blade 111 .

[0177] Alternatively, in other embodiments, the paddling sensor may also only include the water contact sensor 115.
