[0091] Refer to Figures 1 - 4 and in combination with Figure 5 and Figure 13 , Figure 1 FIG. 1 shows a first schematic diagram of an amphibious assist motor provided by some embodiments of the present application. Figure 2 FIG. 2 shows Figure 1 a second schematic diagram of the amphibious assist motor shown in FIG. 1.

[0092] The amphibious assist motor provided by an embodiment of the present application includes a motor body 100, a first wiring component 200, and a second wiring component 300. An installation cavity 113 is formed on the motor body 100. The side wall of the installation cavity 113 is provided with a first installation portion 1131 and a second installation portion 1132 that are spaced apart from each other along the depth direction of the installation cavity 113. The first wiring component 200 is installed in the installation cavity 113 and electrically connected to the motor body 100. The first wiring component 200 is fixedly connected to the first installation portion 1131 and a seal is included therebetween. The second wiring component 300 is used to be electrically connected to an external power supply device. The second wiring component 300 is electrically connected to the first wiring component 200, and a seal is provided at at least one connection between the second wiring component 300 and the first wiring component 200. The second wiring component 300 is fixedly connected to the second installation portion 1132 and a seal is included therebetween.

[0093] When the above-mentioned amphibious assist motor is installed on a watercraft for use, since the first wiring component 200 is electrically connected to the motor body 100, and is fixedly connected to the first installation portion 1131 in the installation cavity 113 of the motor body 100 and a seal is included therebetween, the sealing performance at the connection between the first wiring component 200 and the motor body 100 is relatively good, and the waterproof performance at the connection between the first wiring component 200 and the motor body 100 is relatively good. At the same time, since the second wiring component 300 electrically connected to the external power supply device is electrically connected to the first wiring component 200, and a seal is provided at at least one connection between the second wiring component 300 and the first wiring component 200. The second wiring component 300 is fixedly connected to the second installation portion 1132 and a seal is included therebetween, so that the sealing and waterproof performance at the connection between the second wiring component 300 and the first wiring component 200 is relatively good, and the sealing and waterproof performance at the connection between the second wiring component 300 and the motor body 100 is also relatively good. In this way, the waterproof performance at the wiring end of the entire amphibious assist motor is relatively good, meeting the waterproof use requirements of watercraft.

[0094] It should be noted that the amphibious assist motor provided by the embodiment of the present application can be applied not only to watercraft, such as water-assisted bicycles, etc.; but also to land, without special limitation, as long as it can meet the corresponding waterproof use requirements.

[0095] The waterproof level of the amphibious assist motor provided by the embodiment of the present application can reach the IPX-7 waterproof level, with a relatively high waterproof level.

[0096] The following specifically describes the structure of the amphibious assist motor. Please refer to Figures 6 - 12 and Figures 14 - 22 .

Figure 18 shows Figure 17 The partial enlarged view at C shown. Figure 19 shows Figure 1 The second schematic diagram of the internal structure in the amphibious power-assisted motor. Figure 20 shows Figure 19 The partial enlarged view at D shown. Figure 21 shows Figure 19 The partial enlarged view at E shown. Figure 22 shows Figure 1 The schematic diagram of the first mounting shell 111 in the amphibious power-assisted motor.

[0097] Please refer to Figures 5 - 9 In some embodiments, the first wiring assembly 200 includes a first wiring body 210; the first wiring body 210 is provided with a first connecting portion 211 and a second connecting portion 212 that are connected to each other along a first direction; specifically, the first direction is Figure 17in the zz' direction; and the first connecting portion 211 and the second connecting portion 212 are received in the installation cavity 113; the outer contour of the orthographic projection of the second connecting portion 212 in the first direction is located outside the outer contour of the orthographic projection of the first connecting portion 211 in the first direction; the second connecting portion 212 is fixedly connected to the first installation portion 1131 and a seal is included therebetween. By setting the first wiring body 210 to have a stepped first connecting portion 211 and a second connecting portion 212, and making the second connecting portion 212 fixedly connected to the first installation portion 1131 and a seal is included therebetween, waterproofing is achieved through the stepped structure, so that the sealing and waterproof performance at the connection between the first wiring body 210 and the motor body 100 is relatively good.

[0098] Please refer to Figure 6 and Figure 9 , in some embodiments, the outer contour of the orthographic projection of the first connecting portion 211 in the first direction is an anti-fooling shape. For example, it is a D-shaped structure, so that when the first wiring assembly 200 is installed in the installation cavity 113, the installation position and orientation are unique, not easily prone to errors, and more secure.

[0099] Please refer to Figure 5 , Figure 6 and Figure 10 , in some embodiments, the first wiring assembly 200 further includes a first seal 220; the first seal 220 is sleeved on the first connecting portion 211, and the first seal 220 is disposed between the second connecting portion 212 and the first installation portion 1131. By providing the first seal 220, through the sealing effect of the first seal 220, the sealing and waterproof performance at the connection between the first wiring body 210 and the motor body 100 is further enhanced. At the same time, the first seal 220 can prevent the second connecting portion 212 from shaking relative to the first installation portion 1131.

[0100] Please refer to Figure 6 and Figure 10 , in some embodiments, a first installation hole 221 is formed on the first seal 220; the amphibious power-assisted motor further includes a first connecting member 410 ( Figure 3 as shown), the first connecting member 410 sequentially passes through the second connecting portion 212 and the first installation hole 221, and is fixedly connected to the first installation portion 1131. By setting it like this, the first wiring assembly 200 is fixedly connected to the first installation portion 1131. Not only is it not easy for the first wiring assembly 200 and the first installation portion 1131 to separate after assembly, reducing the possibility of water ingress at their connection, but also the installation process is relatively simple and convenient. In one specific embodiment, the first connecting member 410 is a threaded connecting member, and a threaded connection hole adapted to the first connecting member 410 is formed on the first installation portion 1131.

[0101] See also Figure 6 and Figure 10 In some embodiments, the hole wall of the first mounting hole 221 includes a first hole wall 2211 and a second hole wall 2212 connected to each other; the first hole wall 2211 cooperates with the first connecting member 410, and there is a gap between the second hole wall 2212 and the first connecting member 410. By setting the first mounting hole 221 as two hole walls designed in sections, and one of the hole walls cooperates with the first connecting member 410, and the other hole wall has a certain gap with the first connecting member 410, a gap-avoiding form is formed, which reduces the contact area between the first connecting member 410 and the first mounting hole 221, and prevents the first connecting member 410 from damaging the first sealing member 220. In one specific embodiment, the first hole wall 2211 and the second hole wall 2212 are both "C"-shaped structures, so that the first mounting hole 221 is a semi-sealed and semi-gap-avoiding form.

[0102] See also Figure 5 , Figure 7 and Figure 8 In some embodiments, the second connection portion 212 is recessed along the thickness direction at the circumference of the second connection portion 212 to form an escape space 2121, and the first connection member 410 is at least partially accommodated in the escape space 2121. By providing the escape space 2121 at the circumference of the second connection portion 212, the longitudinal space required for the first connection member 410 during installation can be saved, thereby making the overall height of the first wiring assembly 200 and the first connection member 410 lower after installation, and the structure of the entire amphibious power-assisted motor is more compact and occupies less space.

[0103] See also Figure 5 , Figure 7 and Figure 8 In some embodiments, the first wiring body 210 further includes a third connection portion 213; the third connection portion 213 is connected to a side of the second connection portion 212 away from the first connection portion 211; and the third connection portion 213 is at least partially accommodated in the installation cavity 113; the outer contour of the orthographic projection of the third connection portion 213 along the first direction is located inside the outer contour of the orthographic projection of the second connection portion 212 along the first direction; the third connection portion 213 is fixedly connected to the second wiring assembly 300. By providing the third connection portion 213, the first wiring assembly 200 and the second wiring assembly 300 are fixedly connected through the third connection portion 213, which is relatively simple and convenient.

[0104] In some embodiments, a seal is included between the third connection portion 213 and the second wiring assembly 300, so that the connection between the third connection portion 213 and the second wiring assembly 200 has better sealing performance and is not easy to be water-infiltrated into the connection between the two.

[0105] See also Figure 5 , Figure 7 and Figure 8 In some embodiments, a first power interface 2132 and a first signal line interface 2133 are arranged spaced apart from each other on one side of the third connection portion 213 close to the second wiring assembly 300. By arranging the first power interface 2132 and the first signal line interface 2133 on the third connection portion 213, the power interface and the signal line interface are integrated into one port, thereby reducing the number of wiring interfaces and the cost of waterproofing.

[0106] See also Figure 5 , Figure 7 and Figure 8 In some embodiments, the first power interface 2132 and the first signal line interface are separated by a blocking wall 2134, thereby reducing the impact of the large current generated between the current pins in the power interface on the signal line. In one specific embodiment, the number of the first power interface 2132 is two, the number of the first signal line interface is two, one of the two first power interfaces 2132 is the positive power electrode, and the other is the negative power electrode.

[0107] See also Figure 14 In some embodiments, a second power interface 3111 and a second signal line interface 3112 are configured on a side of the second wiring assembly 300 close to the first wiring assembly 200 . The second power interface 3111 is used to match the first power interface 2132 . The second signal line interface 3112 is used to match the first signal line interface 2133 .

[0108] See also Figure 5 , Figure 8 Combined with Figure 11 In some embodiments, the first wiring assembly 200 further includes a second sealing member 230; the second sealing member 230 is sleeved on the outer periphery of the third connection portion 213 and abuts against the second wiring assembly 300. By providing the second sealing member 230, the sealing and waterproof properties of the connection between the third connection portion 213 and the second wiring assembly 300 are improved, meeting the waterproof use requirements of the water equipment.

[0109] See also Figure 7 , Figure 8 and Figure 18, in some embodiments, a clamping groove 2131 is formed on the outer periphery of the third connecting portion 213; at least a part of the second seal 230 is disposed in the clamping groove 2131. By forming the clamping groove 2131 on the outer periphery of the third connecting portion 213, the connection between the second seal 230 and the third connecting portion 213 is made more stable, and when the second seal 230 is installed on the third connecting portion 213, it is not easy to relatively slide relative to the third connecting portion 213.

[0110] Please refer to Figure 12 and Figure 18 , in some embodiments, a first annular groove 231 and first annular protrusions 232 disposed on both sides of the first annular groove 231 are formed on a side of the second seal 230 facing away from the bottom wall of the clamping groove 2131; when the first wiring assembly 200 and the second wiring assembly 300 are electrically connected, the first annular protrusions 232 can undergo elastic deformation under the extrusion of the second wiring assembly 300 and fill the clamping groove 2131. By providing the first annular groove 231 and the first annular protrusions 232 on the second seal 230, when the first wiring assembly 200 and the second wiring assembly 300 are electrically connected, the entire clamping groove 2131 can be filled under the elastic deformation of the first annular protrusions 232, and thus has better sealing performance. In one specific embodiment, the first wiring assembly 200 and the second wiring assembly 300 are plugged and connected. When it is necessary to detach the first wiring assembly 200 and the second wiring assembly 300 later, due to the elastic deformation ability of the first annular protrusions 232 themselves, the insertion and extraction force is small, which facilitates the disassembly and assembly of the two.

[0111] Please refer to Figure 12 , in some embodiments, the edge of the notch of the first annular groove 231 is provided with a rounded corner, which is beneficial to promoting the deformation of the first annular groove 231 when it is extruded and reducing the stress concentration phenomenon, and thus is beneficial to the expansion of the first annular groove 231.

[0112] Please refer to Figure 12 , in some embodiments, the groove width of the first annular groove 231 gradually increases outward from the bottom wall of the first annular groove 231 along the radial direction of the first annular groove 231. By setting it in this way, when the first wiring assembly 200 and the second wiring assembly 300 are plugged and matched, the second seal 230 is subjected to a radial extrusion force, and the second seal 230 conducts the extrusion force along its own axial and radial directions in a deformed manner, thereby promoting the transmission of the extrusion force along the axial direction of the second seal 230, and finally realizing buffering, reducing the insertion and extraction force, reducing the insertion and extraction wear, effectively improving its own service life, and enabling effective consideration of the design requirements of the waterproof level, insertion and extraction force, and service life at the connection of the two wiring assemblies.

[0113] Please refer toFigure 12 In some embodiments, the cross-sectional shape of the first annular groove 231 is a V-shaped structure with rounded edges, which is easy to process and design. Of course, in other embodiments, the cross-sectional shape of the first annular groove 231 can also be a trapezoidal structure with rounded edges.

[0114] Please refer to Figure 18 In some embodiments, when the first wiring component 200 and the second wiring component 300 are not electrically connected, there is a negative pressure gap 2321 between the side of the first annular protrusion 232 facing away from the first annular groove 231 and the groove wall of the clamping groove 2131. By setting the negative pressure gap 2321, when the second sealing ring seals the insertion gap between the first wiring component 200 and the second wiring component 300, the first annular protrusion 232 on the second sealing ring can undergo elastic deformation and discharge the air in the negative pressure gap 2321, thereby forming the adsorption effect of a negative pressure suction cup. The negative pressure gap 2321 is in a sealed state, further improving the sealing effect of the second seal 230 on the insertion gap between the first wiring component 200 and the second wiring component 300.

[0115] Please refer to Figure 12 In some embodiments, the cross-sectional shape of the first annular protrusion 232 is wavy, which is easy to process and convenient for forming the negative pressure gap 2321.

[0116] Please refer to Figure 13 and Figure 14 In some embodiments, the second wiring component 300 includes a second wiring body 310. The second wiring body 310 is provided with a fourth connecting portion 311 and a fifth connecting portion 312 connected to each other along a first direction; the outer contour of the orthographic projection of the fourth connecting portion 311 along the first direction is located inside the outer contour of the orthographic projection of the fifth connecting portion 312 along the first direction; the fourth connecting portion 311 is inserted and connected to the first wiring component 200. By setting the second wiring body 310 as the stepped fourth connecting portion 311 and fifth connecting portion 312 and making the fourth connecting portion 311 inserted and connected to the first wiring component 200, waterproofing is achieved through the stepped structure, so that the sealing and waterproof performance at the connection between the second wiring component 300 and the first wiring component 200 is better.

[0117] Please refer to Figure 13 and Figure 15 In some embodiments, the second wiring component 300 further includes a third seal 320; the third seal 320 is sleeved on the outer periphery of the fourth connecting portion 311, and the third seal 320 is disposed between the fifth connecting portion 312 and the second mounting portion 1132. By setting the third seal 320, the sealing and waterproof performance between the fifth connecting portion 312 and the second mounting portion 1132 is better.

[0118] Please refer to Figure 1 、 Figure 2 、 Figure 17 and Figure 18 In some embodiments, the amphibious power-assisted motor further includes a second connecting member 420; the second connecting member 420 sequentially passes through the fifth connecting portion 312 and the third seal 320 and is fixedly connected to the second mounting portion 1132. By providing the second connecting member 420, the second wiring assembly 300 is fixedly connected to the second mounting portion 1132. Not only is it difficult for the second wiring assembly 300 and the second mounting portion 1132 to separate after assembly, thereby reducing the possibility of water ingress at the connection between the two, but the installation process is also relatively simple and convenient. In one specific embodiment, the second connecting member 420 is a threaded connecting member, and a threaded connection hole adapted to the second connecting member 420 is formed on the second mounting portion 1132.

[0119] Please refer to Figure 1 and in combination with Figure 16 In some embodiments, the motor body 100 includes a mounting housing 110 and a driving assembly 120 disposed inside the mounting housing 110; a mounting cavity 113 is formed on the mounting housing 110; the driving assembly 120 is electrically connected to the first wiring assembly 200; please refer to Figure 2 、 Figure 4 、 Figure 19 and Figure 20 The amphibious power-assisted motor further includes a transmission assembly 500, and the transmission assembly 500 passes through the mounting housing 110 and is in transmission connection with the driving assembly 120. By setting it in this way, the second wiring assembly 300 transmits the electric energy of the external power supply device to the first wiring assembly 200, the first wiring assembly 200 then transmits the electric energy to the driving assembly 120, and the driving assembly 120 drives the transmission assembly 500 to move, thereby realizing the power-assisted function of the watercraft.

[0120] Please refer to Figure 1 and in combination with Figure 5 and Figure 13 In some embodiments, along the longitudinal extension direction of the mounting cavity 113, the third seal 320 is disposed outside the mounting cavity 113 away from the driving assembly 120, and the second seal 230 is disposed inside the mounting cavity 113 close to the driving assembly 120. By setting it in this way, the sealing at the connection between the motor body 100 of the present amphibious power-assisted motor and the first wiring assembly 200 and the second wiring assembly 300 is a step-by-step sealing from the inside out, so that the inside of the mounting housing 110 can be protected from water ingress to the greatest extent.

[0121] In some of these embodiments, the amphibious power-assisted motor further includes a power supply device (not shown in the figure), and the power supply device is electrically connected to the drive assembly 120; the second wiring assembly 300 includes a signal line, and the signal line is electrically connected to the drive assembly 120 and the power supply device; the signal line is used to control the power on and off of the drive assembly 120. By electrically connecting the signal line to the drive assembly 120 and the power supply device, the power on and off of the drive assembly 120 and the power supply device can be controlled through the signal line, and further the power on and off of the entire motor can be realized.

[0122] In some of these embodiments, when the amphibious power-assisted motor is installed on a water-assisted bicycle, the signal line is also connected to the dashboard at the handlebar of the water-assisted bicycle, so that the driving force of the drive assembly 120 and the power supply device can be observed and adjusted through the dashboard at the handlebar, and further the gear adjustment of the water-assisted bicycle can be realized.

[0123] In some of these embodiments, the first wiring assembly 200 is connected to the circuit board inside the amphibious power-assisted motor, and the circuit board is connected to the power supply device, so that the circuit board can receive both control signals and electricity from the power supply device.

[0124] In some of these embodiments, the transmission assembly 500 is hermetically connected to the penetration part of the installation housing 110. By hermetically connecting the transmission assembly 500 to the penetration part of the installation housing 110, during the use of the water equipment, the connection part between the two is not easily flooded, thus meeting the waterproof use requirements of the water equipment.

[0125] Please refer to Figure 19 and Figure 20 In some of these embodiments, the transmission assembly 500 includes a transmission part 510 and a central shaft 520 that are in transmission connection with each other; the transmission part 510 is in transmission connection with the drive assembly 120 and sleeved on one end of the central shaft 520, and the transmission part 510 is hermetically connected to the installation housing 110 and the central shaft 520; the end of the central shaft 520 away from the transmission part 510 penetrates through the installation housing 110 and is hermetically connected to the installation housing 110. It should be noted that when the amphibious power-assisted motor is installed on a water-assisted bicycle, both ends of the central shaft 520 are connected to the sprocket and the pedal of the bicycle. Therefore, when the drive assembly 120 drives the transmission part 510 to rotate, the central shaft 520 can be driven to rotate around its own rotation axis, and further the sprocket and the pedal connected to both ends of the central shaft 520 can be driven to rotate, so as to realize the function of power assistance. Specifically, the rotation axes of the central shaft 520 and the transmission part 510 are coaxial.

[0126] Please refer to Figure 19 and Figure 20, in some of these embodiments, the transmission assembly 500 further includes a sleeve 530 and a fourth seal 540.

Thus, the waterproof use requirements of the watercraft equipment are effectively met, and the service life of this amphibious assist motor is relatively long.

[0127] Please refer to Figure 20 , in some of these embodiments, on one side of the fourth seal 540 close to the sleeve 530, a second annular groove 541 and second annular protrusions 542 arranged on both sides of the second annular groove 541 are formed; when the fourth seal 540 is installed between the sleeve 530 and the mounting housing 110, the second annular protrusions 542 can undergo elastic deformation under the extrusion of the mounting housing 110 so that the fourth seal 540 is in interference fit with the mounting housing 110. When the fourth seal 540 is installed between the sleeve 530 and the mounting housing 110, through the cooperation of the second annular protrusions 542 and the second annular groove 541, a lip seal structure is formed, making the sealing and waterproofing performance of the fourth seal 540 relatively good, and reducing the insertion and extraction force during the assembly between the sleeve 530 and the mounting housing 110, making the assembly between the two more convenient.

[0128] Please refer to Figure 19 and Figure 20 , in some of these embodiments, the transmission assembly 500 further includes a fifth seal 550. The fifth seal 550 is sleeved on the outer periphery of the central shaft 520 and is in interference fit with the transmission member 510.
