[0032] Embodiments

[0033] Referring to Figure 1 The present embodiment provides a water area movable device 300, comprising a water area carrier 301 and a water area propeller 200, the water area propeller 200 is connected to the water area carrier 301 and used to push the water area carrier 301 to move.

[0034] The water area movable device 300 in the present embodiment can be a passenger ship, a yacht or various ships, and the corresponding water area carrier 301 is a ship body, and the water area propeller 200 is an outboard motor. Of course, the water area movable device 300 can also be a fishing boat, a sailboat or other ships, which are not limited here.

[0035] Continuing to refer to Figure 1 The water area propeller 200 comprises a main engine 201 and a lifting device 100.

[0036] The host 201 comprises a casing 201a, a connecting shaft 202, a propelling driving device 203, a propeller 204, a control device 205 and a steering driving device 206. The steering driving device 206 and the control device 205 are arranged in the casing 201a, the steering driving device 206 is connected to the upper end of the connecting shaft 202 in the vertical direction and is used to drive the connecting shaft 202 to rotate about its rotation axis. One side of the lifting device 100 is connected to the water area carrier 301 and the other side is connected to the connecting shaft 202, the other end of the connecting shaft 202 is connected to the propelling driving device 203 and can drive the propelling driving device 203 to steer under the drive of the steering driving device 206. The propeller 204 is drivingly connected to the propelling driving device 203, and the propelling driving device 203 is used to drive the propeller 204 to rotate to generate propelling force. In use, the user can control the lifting device 100 to act so that the connecting shaft 202 of the water area propeller 200 is lifted relative to the water area carrier 301. When the lifting device 100 drives the connecting shaft 202 to be lifted relative to the water area carrier 301, the propeller 204 can be driven to be out of the water surface or into the water area.

[0037] For reference, Figures 1 to 3 The lifting device 100 in the embodiment comprises a fixed support 11, a rotating support 13, a driving assembly 16 and a sensor assembly 21.

[0038] The fixed support 11 is used to be fixed to the water area carrier 301, for example, connected to the tail of the water area carrier 301. The fixed support 11 can be fixedly connected to the water area carrier 301 by welding, clamping or threaded connection, or integrally arranged with the water area carrier 301. In the embodiment, the fixed support 11 comprises two spaced clamping portions 12.

[0039] The rotating support 13 is rotatably connected between the two clamping portions 12. The rotating support 13 can be rotatably connected to the fixed support 11 by a rotating shaft, a rotating pin or a hinge. For example, see Figure 2 and Figure 3 In the embodiment, the rotating support 13 is rotatably connected to the fixed support 11 by a lifting rotating shaft 37.

[0040] The fixed end of the driving assembly 16 is rotatably connected to the fixed support 11, and the output end of the driving assembly 16 is provided with an abutting rod 17 abutting against the rotating support 13 and rotatingly matched with the rotating support 13. The rotation axis of the abutting rod 17 is perpendicular to the rotation axis of the rotating support 13 rotatably connected to the fixed support 11. In other embodiments, the driving assembly 16 can also be connected to the water area carrier 301.

[0041] When the driving assembly 16 drives the abutting rod 17 to move, the rotating support 13 is driven to rotate relative to the fixed support 11 in the lifting direction, so that the rotating support 13 and the fixed support 11 are relatively rotated, and the main machine 201 is driven to rotate relative to the water area carrier 301 in the lifting direction. The driving assembly 16 can be an electric push rod, a hydraulic cylinder, an air cylinder, an electro-hydraulic cylinder or other devices capable of outputting power. In the embodiment, referring to Figure 4 , the fixed support 11 is provided with a driving rotating shaft 40, the fixed end of the driving assembly 16 is provided with a pivot hole 51, the driving rotating shaft 40 is matched with the pivot hole 51, and a driving bushing 42 is further arranged between the driving rotating shaft 40 and the fixed end of the driving assembly 16. In other embodiments, the driving rotating shaft 40 can also be fixedly arranged on the fixed end of the driving assembly 16 and matched with the fixed support 11.

[0042] In the embodiment, referring to Figure 3 and Figure 5 , the end of the abutting rod 17 is provided with a rotating shaft 19, and the rotating support 13 is rotatably matched with the rotating shaft 19. The rotating axis of the rotating shaft 19 is perpendicular to the rotating axis of the abutting rod 17.

[0043] Specifically, the end of the abutting rod 17 is provided with a connecting protrusion 18, the rotating support 13 is provided with a matching hole 49, the connecting protrusion 18 is provided with a connecting hole 50, the rotating shaft 19 is arranged in the matching hole 49 and the connecting hole 50, the rotating shaft 19 and the connecting protrusion 18 are fixed by a fastener 20, a part of the rotating shaft 19 is connected with the abutting rod 17, and the other part is rotatably matched with the matching hole 49 of the rotating support 13. In other embodiments, the abutting rod 17, the connecting protrusion 18 and the rotating shaft 19 can also be integrally arranged, or the rotating shaft 19 can also be arranged on the outer peripheral wall of the connecting protrusion 18. The structure of the abutting rod 17 rotatably matched with the rotating support 13 can be determined according to actual requirements.

[0044] Referring to Figure 1 and Figure 3 , the sensor assembly 21 is coupled to the rotating support 13 and the abutting rod 17 and is used for sensing the relative rotation amount of the abutting rod 17 and the rotating support 13. Figure 3 The left part of the rotating support 13 in the lifting process is rotatably connected to the upper part of the clamping part 12 through the lifting rotating shaft 37, and the right part of the rotating support 13 is rotatably connected to the abutting rod 17 through the rotating shaft 19. In the lifting process, the two parts do not have relative displacement, and the straight-line distance remains fixed. For details, refer to Figure 6 , Figure 6 , and Figure 3A schematic diagram of the mechanism transmission of the cambering device 100 is shown in FIG. 6. In a first cambering position, the rotating support 13 has a first relative rotation amount a1 with the abutting rod 17, which corresponds to a first cambering angle of the cambering device 100. In a second position, the rotating support 13 has a second relative rotation amount a2 with the abutting rod 17, which corresponds to a second cambering angle of the cambering device 100. The cambering angle (i.e. the trim angle) can be understood as the rotation angle of the rotating support 13 relative to the water area carrier 301 (or the fixed support 11). The corresponding relationship between the relative rotation amount between the rotating support 13 and the abutting rod 17 and the cambering angle detected by the sensor assembly 21 can be obtained by calibration. For example, the relative rotation amount between the rotating support 13 and the abutting rod 17 and the cambering angle of the cambering device 100 at each cambering position can be obtained, and the corresponding relationship between the relative rotation amount and the cambering angle can be established based on the obtained data, so that in subsequent use, the corresponding cambering angle can be obtained directly according to the relative rotation amount between the rotating support 13 and the abutting rod 17 and the pre-stored corresponding relationship. Alternatively, the cambering angle of the cambering device 100 at each cambering position can also be obtained by calculation. For example, taking the first cambering position of the cambering device 100 as an example, the first linear distance dimension L of the rotating connection between the fixed support 11 and the rotating support 13 and the rotating connection between the fixed support 11 and the driving assembly 16, the second linear distance dimension R of the rotating connection between the rotating support 13 and the abutting rod 17 and the rotating connection between the rotating support 13 and the fixed support 11, and the third linear distance dimension (e.g. the length of the driving assembly 16) of the rotating connection between the rotating support 13 and the abutting rod 17 and the fixed end of the driving assembly 16 can be obtained. Figure 6 Figure 6 In the embodiment, S1 is the third linear distance dimension of the cambering device 100 at the first cambering position, S2 is the third linear distance dimension of the cambering device 100 at the second cambering position, and S3 is the driving stroke of the driving assembly 16 when the cambering device 100 switches between the first cambering position and the second cambering position, the relative rotation amount a1 of the rotating support 13 and the abutting rod 17, and other data. The cambering angle of the cambering device 100 at this time is calculated based on one or more of these data. It can be understood that the detection structure is directly arranged at the connection between the rotating support 13 and the fixed support 11, which has a complex structure and is easily affected by external interference, resulting in low detection accuracy. In the embodiment, the connection between the rotating support 13 and the abutting rod 17 is located at an internal position of the cambering device 100, which is less affected by external interference, thereby improving the detection accuracy of the cambering angle.

[0045] In the embodiment, referring to FIG. 6, the rotating support 13 is connected to the fixed support 11 through a rotating connection, and the rotating support 13 is connected to the abutting rod 17 through a rotating connection. The driving assembly 16 is arranged on the fixed support 11 and connected to the rotating support 13 through a rotating connection. The sensor assembly 21 is arranged on the fixed support 11 and connected to the rotating support 13 through a rotating connection. Figure 5 ​, the rotating support 13 comprises a rotating body 14 and two matching protrusions 15, the two matching protrusions 15 are arranged at the rotating body 14 in a spaced manner, and the two ends of the rotating shaft 19 are matched with the two matching protrusions 15 respectively. The two matching protrusions 15 can be respectively provided with two matching holes 49, and a rotating bushing 38 is arranged between the rotating shaft 19 and the matching protrusion 15. The rotating bushing 38 can reduce the rotating friction, so that the rotating of the rotating support 13 relative to the rotating shaft 19 is more smooth. When the abutting rod 17 moves along the length direction, the abutting rod 17 can push the rotating support 13 to rotate relative to the fixed support 11, and at the same time, the two matching protrusions 15 are displaced in space, and then the relative rotation between the rotating shaft 19 and the rotating support 13 occurs, and the relative rotation amount between the rotating shaft 19 and the rotating support 13 detected by the sensor assembly 21 is equal to the relative rotation amount between the rotating support 13 and the abutting rod 17. In other embodiments, the matching protrusion 15 can also be provided with only one, and the rotating shaft 19 is arranged in the matching protrusion 15, and the two ends of the rotating shaft 19 extending out of the matching protrusion 15 are connected with the connecting protrusions 18 respectively.

[0046] In the embodiment, referring to Figure 5 , the two matching protrusions 15 are divided into a matching protrusion 15a and a matching protrusion 15b, the matching protrusion 15a is arranged at the side wall of the rotating body 14, and the matching protrusion 15b is arranged at the middle part of the rotating body 14, so that the matching protrusion 15b is located in the interior of the lifting device 100, and the sensor assembly 21 is coupled between the part of the rotating shaft 19 at the matching protrusion 15b and the rotating support 13, so as to protect the sensor assembly 21. In other embodiments, the sensor assembly 21 can also be coupled between the part of the rotating shaft 19 at the matching protrusion 15a and the rotating support 13.

[0047] In the embodiment, the sensor assembly 21 can be an angle sensor, which can obtain the relative rotation angle between the rotating support 13 and the abutting rod 17, and then output the relative rotation amount a between the abutting rod 17 and the rotating support 13. Specifically, the angle sensor can be a magnetic angle sensor, which can detect the change of the corresponding magnetic flux when the abutting rod 17 and the rotating support 13 produce relative motion, and react the change value of the angle according to the change of the magnetic flux, and the decrease or increase of the magnetic flux can indicate that the change direction of the angle is counterclockwise or clockwise. Of course, it can be understood that the angle sensor can also be a capacitive angle sensor, and when the abutting rod 17 and the rotating support 13 produce relative motion, the resistance value of the capacitive angle sensor will change, and the change value of the resistance value reflects the change value of the angle, and the increase and decrease of the resistance value indicates that the change direction of the angle is counterclockwise or clockwise. The specific type of the angle sensor can be determined according to actual needs, and does not need to be specifically limited.

[0048] In the embodiment, referring to Figure 1The warping device 100 is further provided with a controller 39, and the controller 39 is internally provided with a calculation module capable of receiving the relative rotation amount a and calculating the rotation angle (i.e. the leveling angle) between the rotating support 13 and the fixed support 11 according to the relative rotation amount a.

[0049] In the embodiment, the controller 39 is further electrically connected with the sensor assembly 21 and the driving assembly 16, which can receive the rotation signal input by the user and control the driving assembly 16 to drive the rotating support 13 to rotate relative to the fixed support 11 at the leveling angle.

[0050] In the embodiment, referring to Figure 5 The sensor assembly 21 comprises an inductive chip 22 and a magnetic piece 23; the inductive chip 22 moves with one of the rotating support 13 and the abutting rod 17, and the magnetic piece 23 moves with the other one of the rotating support 13 and the abutting rod 17, and the inductive chip 22 is used to induct the magnetic variable of the magnetic piece 23.

[0051] The inductive chip 22 and the magnetic piece 23 are respectively arranged on the rotating support 13 and the abutting rod 17, which can realize non-contact angle detection, meet the installation requirements in complex environment, reduce the interference from the outside world, and improve the detection accuracy. Moreover, the inductive chip 22 and the magnetic piece 23 have relative displacement in the circumferential direction of the rotating shaft 19 on the abutting rod 17, and have no relative displacement in the axial direction and the radial direction of the rotating shaft 19, which is conducive to further improving the detection accuracy. The inductive chip 22 can be fixedly arranged on one of the rotating support 13 and the abutting rod 17, and the inductive chip 22 can be directly arranged on the rotating support 13 or the abutting rod 17, or indirectly arranged on the rotating support 13 or the abutting rod 17 through other connecting structures. The magnetic piece 23 can be fixedly arranged on the other one of the rotating support 13 and the abutting rod 17, and the magnetic piece 23 can be directly arranged on the rotating support 13 or the abutting rod 17, or indirectly arranged on the rotating support 13 or the abutting rod 17 through other connecting structures.

[0052] When the abutting rod 17 and the rotating support 13 appear relative rotation, the inductive chip 22 and the magnetic piece 23 synchronously appear relative rotation, the inductive chip 22 inducts the magnetic field change of the magnetic piece 23, and outputs the magnetic variable of the magnetic piece 23 to the controller 39, the controller 39 judges the relative rotation angle between the inductive chip 22 and the magnetic piece 23 according to the magnetic variable of the magnetic piece 23, and calculates the relative rotation amount a of the abutting rod 17 and the rotating support 13, and finally calculates the relative rotation amount (i.e. the warping angle / leveling angle) between the rotating support 13 and the fixed support 11.

[0053] In the embodiment, referring to Figure 5The rotating support 13 is provided with a sealed cavity 59, and the inductive chip 22 and the magnetic member 23 are arranged in the sealed cavity 59. The sealed cavity 59 can seal and protect the inductive chip 22 and the magnetic member 23, so as to avoid water in the water area from entering the sealed cavity 59 and affecting the detection accuracy and service life of the inductive chip 22 and the magnetic member 23 during the operation of the device 100. One of the inductive chip 22 and the magnetic member 23 connected to the abutting rod 17 is connected to the abutting rod 17 outside the sealed cavity 59 through a sealing connection structure in the sealed cavity 59, so as to realize the follow-up movement of the abutting rod 17.

[0054] In the embodiment, as shown in Figure 5 , the inductive chip 22 is fixed in the sealed cavity 59, and the magnetic member 23 is rotatably arranged in the sealed cavity 59. In the embodiment, the magnetic member 23 can be connected to the rotating shaft 19 in multiple ways. In addition to the connection through the connection structure as described above, other ways can also be used. For example, as shown in Figure 7 , the end of the abutting rod 17 is provided with a connecting magnetic block 43, and the polarity of the connecting magnetic block 43 is different from that of the magnetic member 23, so that the magnetic member 23 is indirectly connected to the rotating shaft 19 and can rotate relative to the inductive chip 22 under the driving of the abutting rod 17. A rotating bearing 44 can be arranged in the sealed cavity 59, and the magnetic member 23 is arranged in the rotating bearing 44, so as to reduce the rotating friction of the magnetic member 23, ensure that the magnetic member 23 can rotate under the driving of the connecting magnetic block 43, and reduce errors.

[0055] In the embodiment, as shown in Figure 5 , the driving assembly 16 further includes a first connecting part 25, one end of the first connecting part 25 is connected to the rotating shaft 19, and the other end of the first connecting part 25 extends into the sealed cavity 59 and is connected to the magnetic member 23, so that the magnetic member 23 is arranged corresponding to the inductive chip 22. In the embodiment, the first connecting part 25 and the rotating shaft 19 can be fixedly connected through screws or pins, or can be integrally arranged with the rotating shaft 19.

[0056] In the embodiment, as shown in Figure 5 , the rotating axis of the first connecting part 25 coincides with the rotating axis of the rotating shaft 19, so that the angle of the rotating shaft 19 relative to the rotating support 13 is the angle of the first connecting part 25 relative to the rotating support 13, so as to reduce the number of angle conversion times and reduce errors caused by conversion, and the requirement for the magnetic field of the magnetic member 23 is lower, which is conducive to reducing the cost. In other embodiments, the rotating axis of the first connecting part 25 and the rotating axis of the rotating shaft 19 can be arranged staggered, which is more conducive to completing the installation of the first connecting part 25 under the rotating support 13 with a complex structure, and has a wider application range.

[0057] In the embodiment, as shown in Figure 5The rotating support 13 comprises a receiving housing 26, which defines a sealed cavity 59, and the first connecting part 25 penetrates into the sealed cavity 59 from the outside of the receiving housing 26. In other embodiments, the sealed cavity 59 can also be arranged in the rotating shaft 19, i.e., the sealed cavity 59 does not need to be arranged on the rotating support 13 (see the description of the following embodiments).

[0058] In the embodiment, as shown in Figure 5 The receiving housing 26 is fixedly arranged on the rotating body 14 and located on the side of the cooperating protrusion 15b away from the cooperating protrusion 15a, so as to better protect the receiving housing 26. In other embodiments, the receiving housing 26 can also be arranged between the cooperating protrusion 15a and the cooperating protrusion 15b. The receiving housing 26 can be fixedly connected with the rotating body 14 by screws or pins, or can be integrally arranged with the rotating body 14.

[0059] In the embodiment, as shown in Figure 5 The end wall of the receiving housing 26 facing the first connecting part 25 is provided with a cooperating opening 52, and the side of the sealed cavity 59 close to the cooperating opening 52 is provided with a connecting bearing 31, and the first connecting part 25 penetrates through the cooperating opening 52 and cooperates with the connecting bearing 31. The connecting bearing 31 can lubricate and reduce the rotation friction of the first connecting part 25 relative to the receiving housing 26. In other embodiments, the rotating shaft 19 can also cooperate with the connecting bearing 31, and the first connecting part 25 is completely arranged in the sealed cavity 59.

[0060] In the embodiment, as shown in Figure 5 The lifting device 100 further comprises a first sealing member 27, which is sleeved on the first connecting part 25 and abuts against the inner wall of the sealed cavity 59, so as to seal the connection between the first connecting part 25 and the receiving housing 26. In the embodiment, the end wall of the receiving housing 26 facing the first connecting part 25 is provided with a cooperating opening 52, and the first sealing member 27 can be a first sealing ring 32, which is sealingly cooperated between the first connecting part 25 and the cooperating opening 52, so as to facilitate the disassembly and assembly of the first sealing member 27, the first connecting part 25 and the receiving housing 26. In other embodiments, the sealing structure between the first sealing member 27 and the first connecting part 25 can also be omitted, for example, as shown in Figure 8 The first sealing member 27 can be a sealing body 33 filled in the part of the sealed cavity 59 close to the first connecting part 25, which can be polyurethane potting adhesive, silicone potting adhesive or epoxy resin potting adhesive and filled in the sealed cavity 59 by potting. The end of the first connecting part 25 extends into the sealing body 33 and is connected with the magnetic member 23, which can further improve the sealing effect and increase the protection effect of the inductive chip 22 and the magnetic member 23 in the sealed cavity 59.

[0061] In the embodiment, as shown in Figure 5The side of the receiving housing 26 away from the first connecting part 25 is provided with an opening 53, and the opening 53 is provided with an end cover 28. The end cover 28 is provided with a waterproof joint 29, and the waterproof joint 29 is used to receive the cable 24 connected with the induction chip 22. In other embodiments, the cable 24 can also directly pass through the end cover 28 without passing through the waterproof joint 29. Alternatively, the induction chip 22 and the controller 39 can also be connected through a wireless transmission mode such as Bluetooth, so that the side of the receiving housing 26 away from the first connecting part 25 can also not have the opening 53, but directly form a closed side wall. In the embodiment, the end cover 28 is fixed to the receiving housing 26 through a locking part 41.

[0062] In the embodiment, referring to Figure 5 , a second sealing part 35 is arranged between the end cover 28 and the receiving housing 26, and the second sealing part 35 is used to seal the connection between the end cover 28 and the receiving housing 26. The second sealing part 35 can be a second sealing ring 36 which is sealingly fitted between the end cover 28 and the receiving housing 26, or can be a sealing filling structure filled in a sealing cavity 59. The cable 24 connected with the induction chip 22 can pass through the sealing filling structure to extend out of the sealing cavity 59.

[0063] In the embodiment, referring to Figure 5 , the protruding part 30 of the end cover 28 extends into the receiving housing 26, and the side surface of the protruding part 30 is provided with a side sealing groove 58, and the second sealing part 35 is arranged in the side sealing groove 58. The protruding part 30 can be connected with the receiving housing 26 through a thread or an interference fit. The second sealing part 35 can be a sealing ring fitted in the side sealing groove 58, or can be a sealing band wound around the side surface of the protruding part 30. When the second sealing part 35 is a sealing band, the side surface of the protruding part 30 can not be provided with the side sealing groove 58.

[0064] In other embodiments, the end surface of the end cover 28 is provided with an end sealing groove 57, and the second sealing part 35 is arranged in the end sealing groove 57. It also has a good sealing effect. In still other embodiments, the end surface of the receiving housing 26 facing the end cover 28 can also be provided with a sealing groove for receiving the second sealing part 35. Alternatively, the end surface of the receiving housing 26, the end surface of the end cover 28, and the outer peripheral surface of the protruding part 30 can each be provided with a sealing groove and be provided with the second sealing part 35, so as to greatly enhance the sealing effect and greatly reduce the possibility of water entering the sealing cavity 59.

[0065] In another embodiment of the embodiment, referring to Figure 9The magnetic member 23 is arranged inside the portion of the first connecting part 25 extending into the sealing cavity 59, so as to better protect the magnetic member 23. In this embodiment, the inductive chip 22 can be wrapped by the sealing body 33 in the sealing cavity 59, so as to seal the inductive chip 22. Therefore, the first connecting part 25 and the accommodating shell 26 do not need to be additionally provided with a sealing ring or other sealing structure, and the processing difficulty of the cooperation between the first connecting part 25 and the accommodating shell 26 can be reduced.

[0066] Another embodiment of the warping device 100 will be described below with reference to Figure 10 The difference between the warping device 100 and the foregoing warping device 100 is that, in this embodiment, the inductive chip 22 is rotatably arranged, and the magnetic member 23 is fixedly arranged in the sealing cavity 59.

[0067] Referring to Figure 10 In this embodiment, the magnetic member 23 is fixedly arranged in the sealing cavity 59, and the inductive chip 22 is rotatably arranged in the sealing cavity 59. Therefore, when the inductive chip 22 rotates relative to the magnetic member 23, the position of the magnetic field detected by the inductive chip 22 also changes, so that the relative rotation amount of the inductive chip 22 and the magnetic member 23 can be detected, and the relative rotation amount of the rotating support 13 and the fixed support 11 can be calculated. In this embodiment, the magnetic member 23 is a permanent magnet, which can be connected to the outside without a cable 24. The accommodating shell 26 can be provided with only the cooperating opening 52, and does not need to be provided with a hole in other areas. Of course, in other embodiments, the magnetic member 23 can be an electromagnet, and the specific structure of the accommodating shell 26 can refer to the structure in the foregoing embodiment, so that the electric wire connected to the electromagnet can pass into the accommodating shell 26, and details are not described herein.

[0068] In this embodiment, one end of the rotating shaft 19 extends into the sealing cavity 59, the inductive chip 22 is arranged at the end of the rotating shaft 19 extending into the sealing cavity 59, and the rotating shaft 19 is hollow and used for accommodating the cable 24 connected to the inductive chip 22. The rotating shaft 19 can directly extend into the sealing cavity 59, so that the first connecting part 25 does not need to be additionally provided. The rotating shaft 19 is provided with the hollow hole 54, which can facilitate the passage of the cable 24 and better protect the cable 24, so as to ensure the normal operation of the inductive chip 22.

[0069] In this embodiment, referring to Figure 10 The hollow hole 54 can be a through hole, one end of the rotating shaft 19 away from the magnetic member 23 can be provided with the end cover 28 and the waterproof joint 29 allowing the cable 24 to pass through, and the connection structure of the cable 24, the waterproof joint 29 and the rotating shaft 19 can refer to the sealing structure of the end cover 28, the waterproof joint 29 and the accommodating shell 26, and details are not described herein. Figure 5

[0070] ​In the embodiment, the rotating shaft 19 and the accommodating shell 26 are connected by the first sealing member 27. The specific matching structure can refer to the foregoing embodiment, and will not be described here again.

[0071] Another embodiment of the warping device 100 will be described below with reference to Figure 11 and Figure 12 . The difference between the warping device 100 and the foregoing warping device 100 is that, in the embodiment, the inductive chip 22 is arranged in the sealed cavity 59, and the magnetic member 23 is arranged outside the sealed cavity 59.

[0072] In the embodiment, one of the rotating support 13 and the rotating shaft 19 is provided with the sealed cavity 59, the inductive chip 22 is accommodated in the sealed cavity 59, and the magnetic member 23 is arranged outside the sealed cavity 59. The sealed cavity 59 can better protect the inductive chip 22 from water. The magnetic member 23 is not easily affected by water in actual use, and is arranged outside the sealed cavity 59, so that the magnetic member 23 does not need to pass through the first connecting part 25 into the accommodating shell 26, which improves the sealing effect of the sealed cavity 59, facilitates the overall assembly of the warping device 100, improves the assembly efficiency, and reduces the assembly difficulty. In addition, since the accommodating shell 26 only needs to be provided with the opening 53 for the cable 24 to enter and exit, the sealing difficulty of the accommodating shell 26 is also reduced.

[0073] For example, in the embodiment, as shown in Figure 11 , the opening 53 is arranged on the side of the accommodating shell 26 away from the abutting rod 17, the sealed cavity 59 is filled with the sealing body 33, the opening 53 is used to allow the cable 24 to pass into the sealed cavity 59 and be connected with the inductive chip 22, and the sealed cavity 59 can be directly filled with the sealing body 33 such as glue, which can also fix and seal the connection between the end cover 28 and the accommodating shell 26.

[0074] In the embodiment, as shown in Figure 11 , the magnetic member 23 is arranged at the end of the rotating shaft 19 facing the accommodating shell 26. In this way, the rotating axis of the magnetic member 23 coincides with the rotating axis of the inductive chip 22, and is parallel to or coincides with the rotating axis of the rotating shaft 19, so that the detected data can be directly calculated without multiple conversions, the conversion error is reduced, and the detection accuracy of the warping angle is further improved. In the embodiment, the rotating axis of the magnetic member 23 refers to the center line of the magnetic member 23, and the rotating axis of the inductive chip 22 refers to the center line of the inductive chip 22.

[0075] In other embodiments, as shown in Figure 12The rotation axis of the magnetic member 23 can also be arranged to be offset from the rotation axis of the inductive chip 22, and both can achieve the effect that the inductive chip 22 detects the magnetic field change of the magnetic member 23. For example, the magnetic member 23 is arranged on the radial side of the rotation shaft 19, and the magnetic member 23 can be specifically a magnetic ring 23a which is sleeved on the rotation shaft 19. When the driving assembly 16 is in operation, the magnetic ring 23a rotates relative to the inductive chip 22, and the relative rotation amount of the rotation shaft 19 and the rotating support 13 can also be detected by sensing the magnetic field change of the magnetic ring 23a. In this embodiment, the arrangement of the magnetic member 23, the rotation shaft 19 and the inductive chip 22 is more compact.

[0076] In the following, the warping device 100 of another embodiment is described with reference to the drawings. Figures 13 to 15 The difference between the warping device 100 and the foregoing warping device 100 is that, in this embodiment, the sealed cavity 59 is arranged in the rotation shaft 19.

[0077] Referring to Figure 13 In this embodiment, the end of the abutting rod 17 is provided with the rotation shaft 19, the rotating support 13 is rotatably connected to the rotation shaft 19, the rotation shaft 19 is provided with the sealed cavity 59, and the inductive chip 22 and the magnetic member 23 are both accommodated in the sealed cavity 59. Since the inductive chip 22 and the magnetic member 23 are both integrated in the sealed cavity 59 of the rotation shaft 19, the assembly difficulty of the sensor assembly 21 and the rotation shaft 19 is reduced, and the rotation shaft 19 and the sensor assembly 21 can be pre-assembled as an integral assembly to improve the production efficiency of the warping device 100.

[0078] In this embodiment, referring to Figure 13 The inductive chip 22 is fixed in the sealed cavity 59, and the magnetic member 23 is rotatably connected to the sealed cavity 59.

[0079] In this embodiment, the magnetic member 23 is connected to the rotating support 13 and is arranged correspondingly to the inductive chip 22. The warping device 100 further comprises a second connecting portion 47, one end of the second connecting portion 47 is arranged on the rotating support 13, and the other end of the second connecting portion 47 extends into the sealed cavity 59 and is connected to the magnetic member 23. When the rotation shaft 19 rotates relative to the rotating support 13, the second connecting portion 47 also rotates, so that the magnetic member 23 rotates relative to the inductive chip 22, so that the inductive chip 22 obtains the relative rotation amount of the rotation shaft 19 and the rotating support 13.

[0080] In this embodiment, the rotation shaft 19 is hollow and is used for accommodating the cable 24 connected to the inductive chip 22. Specifically, the rotation shaft 19 is provided with a hollow hole 54, and the cable 24 is connected to the inductive chip 22 and extends out of the hollow hole 54, and the cable 24 is well protected, ensuring the normal operation of the inductive chip 22.

[0081] In the embodiment, the warping device 100 further comprises a chamber seal 46, which is sleeved on the second connecting portion 47 and abuts against the inner wall of the sealing chamber 59 to seal the connection between the second connecting portion 47 and the rotating shaft 19. In this way, water or foreign matter from the outside can be prevented from entering the hollow hole 54 through the gap between the second connecting portion 47 and the hollow hole 54, thereby better protecting the inductive chip 22. In the embodiment, the inductive chip 22 can be fixedly connected to the rotating shaft 19 through the sealing structure, so that the sealing chamber 59 can be formed between the chamber seal 46 and the inductive chip 22. In other embodiments, the sealing chamber 59 can also be formed in other ways. The chamber seal 46 can be a sealing ring or a sealing gel or other sealing structures. For example, referring to Figure 14 , the middle part of the rotating shaft 19 can be provided with a sealing protrusion 48 that allows only the cable 24 to pass through, and the cable 24 is sealingly fitted in the sealing protrusion 48 through the third sealing ring 60, so that the sealing chamber 59 can be formed between the chamber seal 46 and the sealing protrusion 48. Therefore, there are various ways to form the sealing chamber 59 in the rotating shaft 19, which need not be specifically limited.

[0082] In the embodiment, referring to Figure 13 , the end of the rotating shaft 19 away from the second connecting portion 47 is provided with a first aperture 55, and the first aperture 55 is provided with an end cover 28, and a waterproof connector 29 is provided through the end cover 28, which is used to accommodate the cable 24 connected to the inductive chip 22. A second sealing member 35 is provided between the end cover 28 and the rotating shaft 19, which is used to seal the connection between the end cover 28 and the rotating shaft 19. The connection structure of the cable 24, the waterproof connector 29 and the rotating shaft 19 can refer to the sealing structure of the end cover 28, the waterproof connector 29 and the accommodation shell 26 in Figure 5 , which will not be described here again.

[0083] In the embodiment, the side of the rotating shaft 19 towards the second connecting portion 47 is provided with a second aperture 56, and the second aperture 56 is provided with a cooperating bearing 45, and the second connecting portion 47 cooperates with the cooperating bearing 45. The cooperating bearing 45 can reduce the rotational friction between the rotating shaft 19 and the second connecting portion 47, so as to avoid that the relative rotation angle between the inductive chip 22 and the magnetic member 23 and the actual relative rotation angle between the rotating shaft 19 and the second connecting portion 47 are too large, and improve the detection accuracy of the sensor assembly 21.

[0084] In another embodiment, referring to Figure 15 , the magnetic member 23 is fixed in the sealing chamber 59, and the inductive chip 22 is rotatably fitted in the sealing chamber 59. Moreover, the inductive chip 22 is connected to the rotating support 13 through the second connecting portion 47. In this embodiment, the relevant structures of the rotating shaft 19, the second connecting portion 47 and the sensor assembly 21 can refer to the description in the above embodiment. Figure 13The magnetic member 23 can be a magnetic ring 23a in this embodiment, so that the cable 24 connected to the inductive chip 22 can pass through.

Although the present application is described in detail with reference to the above preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalent replaced without departing from the spirit and scope of the present application.
