DETAILED DESCRIPTION

[0060] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, but are not to be construed as limiting the present disclosure.

[0061] Delivering items using drones requires efficiency and safety, so the drone's mounting system must also be able to mount quickly and ensure there is no risk of falling off during flight.

[0062] In conventional technologies, the target scenarios for drone delivery include scenic spots, villas, and sparsely populated areas such as overseas. At the same time, it needs to meet the needs of group delivery, that is, the mounting mechanism needs to be compatible with the ability to mount single or multiple cargo boxes.

[0063] As shown in Figures 1 to 14, an embodiment of the present disclosure provides a mounting mechanism that is assembled on the fuselage of a drone when in use. The mounting mechanism includes a drive unit 100 and a plurality of mounting units 200, wherein:

[0064] The mounting portion 200 is used to mount a preset target object 300. In the embodiment provided in the present application, the preset target object 300 is a cargo box, and the cargo box is provided with a mounting structure corresponding to the mounting portion 200, which is used to realize the locking function with the mounting portion 200. Those skilled in the art can know that the preset target object 300 can also be an object in other fields to meet the mounting requirements of multiple fields. The above-mentioned drone can be any model of drone used to transport goods, and drones with different load capacities can be selected according to the size and weight of the transported cargo box. Accordingly, the drone mounting mechanism provided in the present application can be adaptively designed according to the model of the drone and the size of the cargo box for application in different logistics scenarios. The present application does not impose specific restrictions on this.

[0065] The mounting portion 200 has a first posture and a second posture. When the mounting portion 200 is in the first posture, the preset target body 300 is locked on the mounting portion 200 and can reach the preset destination with the drone. After arriving, the preset target body 300 needs to be unloaded. At this time, the mounting portion 200 is in the second posture, the preset target body 300 and the mounting portion 200 are unlocked, and the preset target body 300 is separated from the mounting portion 200, completing the delivery operation.

[0066] The drive unit 100 is used to drive multiple mounting units 200 to move synchronously or each mounting unit 200 to move independently. The output end of the drive unit 100 is in transmission connection with the mounting unit 200, and the driving force provided causes the mounting unit 200 to rise and fall vertically along the direction of gravity. The multiple mounting units 200 can rise and fall synchronously together, or the drive unit 100 can independently control a single mounting unit 200 to rise and fall independently. Specifically:

[0067] When multiple mounting parts 200 are structures that can be raised and lowered synchronously, when the mounting part 200 needs to mount a preset target object 300, the driving part 100 drives the multiple mounting parts 200 to descend synchronously. After some or all of the mounting parts 200 have mounted the preset target object 300, the driving part 100 drives the multiple mounting parts 200 to rise synchronously. After the drone arrives at a destination, the driving part 100 drives the multiple mounting parts 200 to descend synchronously. After unloading a single or multiple preset target objects 300, the drone arrives at the next destination.

[0068] When a single mounting part 200 is in a structure that is independently raised and lowered, when the mounting part 200 needs to mount a preset target object 300, the driving part 100 drives one or more mounting parts 200 of the same number as the preset target objects 300 to descend synchronously, while the other mounting parts 200 can remain stationary. After the lowered mounting part 200 has mounted the corresponding preset target object 300, the driving part 100 drives these mounting parts 200 to rise. After the drone arrives at a destination, the driving part 100 drives the mounting part 200 that needs to unload the preset target object 300 to descend. After the mounting part 200 unloads one or more preset target objects 300 at this destination, the drone arrives at the next destination and unloads other corresponding preset target objects 300.

[0069] Several embodiments are listed below to further illustrate the structure and distribution of the mounting portion 200 and the driving portion 100 of the present application. Those skilled in the art will appreciate that more variations can be designed based on the following embodiments, all of which fall within the scope of protection of the present disclosure.

[0070] Example 1

[0071] 1 to 9 , in this embodiment, when the preset target body 300 is partially hidden, a handle 301 is provided on the preset target body 300. The handle 301 is a handle structure having a hanging groove 302. The handle 301 is used to form a locking fit with the mounting portion 200. The mounting portion 200 includes a first guide slide 201, a first locking paddle 203, a first driving member 204, a locking slider 205, and a locking latch 206.

[0072] 4 to 6 , the first guide slide 201 is used to guide the movement of the preset target 300. The first guide slide 201 is arranged obliquely to the direction of gravity. When the preset target 300 is assembled, the first guide slide 201 is inserted into the hanging groove 302, and the handle 301 climbs upward along the first guide slide 201. In the embodiment provided by the present application, a support platform 202 is provided at the end of the first guide slide 201. When the handle 301 climbs to the end of the first guide slide 201, the handle 301 can be supported on the support platform 202, thereby improving the stability and reliability of the mounting of the preset target 300. When the preset target 300 is unloaded, since the first guide slide 201 is arranged obliquely, the handle 301 slides down along the first guide slide 201 by relying on the deadweight of the preset target 300, and the preset target 300 is separated from the mounting portion 200.

[0073] The first driving member 204 and the locking slider 205 are both arranged above the first guide slide 201. In a feasible embodiment, the first driving member 204 is a screw motor, and a trapezoidal screw is connected to the output shaft of the screw motor. The locking slider 205 is provided with an internal threaded hole, and the trapezoidal screw thread is engaged with the internal threaded hole of the locking slider 205. The screw motor works to drive the trapezoidal screw to rotate, and through the engagement with the thread of the locking slider 205, the rotation of the trapezoidal screw is converted into linear movement of the locking slider 205. Technicians in this field can know that the first driving member 204 can also use other types of driving methods, such as linear cylinder drive, etc., which are not limited here.

[0074] The first locking paddle 203 is rotatably arranged on the moving path of the preset target body 300. Specifically, a first mounting groove 2011 is provided on the first guide slide 201, and the first locking paddle 203 is pivotally connected to the first mounting groove 2011. The first locking paddle 203 includes a first front paddle 2031 and a first rear paddle 2032. A first locking space 2033 is formed between the first front paddle 2031 and the first rear paddle 2032. The first locking space 2033 forms a "V"-shaped structure. The first front paddle 2031 and the first rear paddle 2032 constitute two sides of the "V"-shaped structure. Under normal circumstances, the first front paddle 2031 is located above the first mounting groove 2011, and the first rear paddle 2032 is accommodated in the first mounting groove 2011.

[0075] The locking pin 206 is elastically and telescopically arranged on the locking slider 205. In a feasible embodiment, a first accommodating cavity 2051 is provided on the locking slider 205, and a first spring 207 is provided in the first accommodating cavity 2051. One end of the locking pin 206 extends into the first accommodating cavity 2051 and abuts against the first spring 207. The other end of the first spring 207 abuts against the inner wall of the first accommodating cavity 2051. The other end of the locking pin 206 extends out of the first accommodating cavity 2051, and a guide sliding slope is provided at the end of the locking pin 206.

[0076] When the handle 301 of the preset target body 300 moves along the first guide slide 201, it first contacts the first front paddle 2031. As the preset target body 300 moves, it pushes the first locking paddle 203 to rotate, and the first rear paddle 2032 rotates to the top of the first guide slide 201. The handle 301 falls into the first locking space 2033. The first rear paddle 2032 contacts the guide slope of the locking pin 206. Due to the inclined setting of the guide slope, a vertical component of force is applied to the guide slope, thereby driving the locking pin 206 to move into the first accommodating cavity 2051. , squeezing the first spring 207, the first spring 207 accumulates elastic restoring force, and after the first rear paddle 2032 passes over the locking pin 206, the locking pin 206 loses its support, and the elastic restoring force of the first spring 207 is released, causing the locking pin 206 to return to its initial position. At this time, the mounting portion 200 is in the first posture, the back of the locking pin 206 abuts against the first rear paddle 2032, and the first front paddle 2031 abuts against the supporting platform 202 to limit the rotation of the first locking paddle 203, and the preset target body 300 is locked in the first locking space 2033 to achieve stable mounting.

[0077] When the preset target object 300 needs to be unloaded, the first driving member 204 drives the locking slider 205 to move, so that the locking pin 206 moves away from the first rear paddle 2032, and the first rear paddle 2032 loses its abutment. At this time, when the mounting part 200 is in the second posture, the locking pin 206 and the first rear paddle 2032 are released from the abutment, and the preset target object 300 can be separated from the first locking space 2033 by human power or other mechanical force.

[0078] Furthermore, abutment block 2052 is provided on the locking slider 205. When the preset target body 300 is locked in the first locking space 2033, the first rear paddle 2032 is located on the moving path of the abutment block 2052. When the preset target body 300 needs to be unloaded, the first driving member 204 drives the locking slider 205 to move. After the locking pin 206 moves away from the first rear paddle 2032, the abutment block 2052 abuts against the first rear paddle 2032, driving the first rear paddle 2032 to rotate in the opposite direction. The handle 301 of the preset target body 300 moves from the support platform 202 to the first guide slide 201. The preset target body 300 continues to move under the action of its own gravity and leaves the first locking space 2033.

[0079] In this embodiment, a first in-position switch 208 and a second in-position switch 209 are provided in the mounting portion 200. The first in-position switch 208 is located on the rotation path of the first front paddle 2031. When the preset target body 300 is locked in the first locking space 2033, the first in-position switch 208 and the second in-position switch 209 are both triggered, and the position of the locking slider 205 is locked.

[0080] Specifically, the first in-position switch 208 is located on the support platform 202. When the first front paddle 2031 rotates to the end of the rotation path, the first front paddle 2031 triggers the first in-position switch 208. The second in-position switch 209 is located on the moving path of the locking pin 206. After the first rear paddle 2032 passes over the locking pin 206, the locking pin 206 returns to the initial position under the elastic restoring force of the first spring 207. At this time, the second in-position switch 209 is triggered by the locking pin 206. The double signal is communicated to the system to confirm that the handle 301 is mounted in place. The trapezoidal lead screw has a mechanical self-locking function to prevent the locking slider 205 from moving.

[0081] In this embodiment, the driving unit 100 includes a first frame 101, which serves as a mounting frame and provides a mounting base for the installation of various components. The driving unit 100 also includes a first driving assembly, a first winch 105, a first lifting rope 106, and a lifting beam 107. The first driving assembly includes a first driving motor 102, a first transmission gear set 103, and a first transmission shaft 104, wherein:

[0082] The output end of the first drive motor 102 is connected to the first transmission shaft 104 through the first transmission gear set 103. The first drive motor 102 has current detection and feedback of load changes. The landing feedback of the preset target body 300 is realized through load current detection. The first transmission gear set 103 includes a plurality of meshing gears to transmit the driving force of the first drive motor 102 to the first transmission shaft 104, driving the first transmission shaft 104 to rotate with its own axis as the center line. The number and distribution of gears in the first transmission gear set 103 can be determined according to actual needs.

[0083] The first winch 105 is arranged on the first transmission shaft 104, and the first winch 105 rotates synchronously with the first transmission shaft 104. One end of the first lifting rope 106 is wound around the first winch 105, and the other end of the first lifting rope 106 is connected to the lifting beam 107. The first frame 101 is provided with multiple guide wheels and tension wheels to form an arrangement path for the first lifting rope 106. The retraction and extension process of the first lifting rope 106 is structurally guided so that it will not be caught by spatial obstacles such as tree branches during the rising or descending process when there is no load.

[0084] In a feasible embodiment, two first winches 105 are provided on the first transmission shaft 104, and two first lifting ropes 106 are wound around the two first winches 105 respectively. After being guided by the guide wheel and the tension wheel, the first lifting ropes 106 are respectively connected to the opposite ends of the lifting beam 107 to improve the stability and reliability of the lifting beam 107. During the loading process, due to the existence of the guide wheel and the lifting beam 107, the possibility of the first lifting rope 106 being wound is greatly reduced.

[0085] The first drive motor 102 is working, and the driving force is transmitted to the first transmission shaft 104 via the first transmission gear set 103. The rotation of the first transmission shaft 104 drives the first winch 105 to rotate synchronously, thereby driving the lifting beam 107 to rise and fall. Multiple mounting parts 200 are all connected to the lifting beam 107 to achieve synchronous lifting of multiple mounting parts 200 with high efficiency.

[0086] A control unit 108 may also be provided on the suspension beam 107, which integrates a power supply, a remote control panel and a wireless charging module. The material of the first suspension rope 106 may be metal or non-metal, which is not limited here. When the first suspension rope 106 is made of metal, a conductive metal soft rope coated with an insulating layer may be used, and the power supply is uniformly supplied by the electric drive part and transmitted to the end, and the power supply and wireless charging module integrated in the suspension beam 107 may be omitted.

[0087] Further, referring to FIG7 to FIG9 , a positioning protrusion 1071 is provided on the hanging beam 107 , a positioning hole 1072 is provided on the outer circumference of the positioning protrusion 1071 , and the mounting mechanism further includes a positioning matching block 109 , a positioning pin 110 and a second driving member 1182111 , wherein:

[0088] The positioning matching block 109 is arranged on the first frame 101, and the bottom recess of the positioning matching block 109 is provided with a positioning groove 1091. The positioning protrusion 1071 is arranged in a one-to-one correspondence with the positioning matching block 109. The positioning matching block 109 is located above the positioning protrusion 1071, and the positioning groove 1091 is located on the moving path of the positioning protrusion 1071. When the hanging beam 107 moves to the preset position, the positioning protrusion 1071 extends into the positioning groove 1091. In a feasible embodiment, the positioning protrusion 1071 is provided at both ends of the hanging beam 107, and the first lifting rope 106 passes through the positioning groove 1091 of the positioning matching block 109, and then is connected to the positioning protrusion 1071, thereby realizing automatic alignment of the positioning protrusion 1071 and the positioning groove 1091, and calibrating the position of the hanging beam 107.

[0089] The output end of the second driving member 111 is connected to the positioning pin 110 to drive the positioning pin 110 to reciprocate in the positioning matching block 109. In this embodiment, the second driving member 111 is a driving cylinder, and the end of the piston rod of the driving cylinder is connected to one end of the positioning pin 110 to realize the linear reciprocating movement of the positioning pin 110. The other end of the positioning pin 110 extends into the positioning groove 1091. When the positioning protrusion 1071 extends into the positioning groove 1091, it reaches the preset position. The positioning hole 1072 is located on the moving path of the positioning pin 110. The second driving member 111 drives the positioning pin 110 to extend forward and embed into the positioning hole 1072, thereby limiting the lifting and lowering of the positioning protrusion 1071, so that the hanging beam 107 is fixed to the first frame 101 to prevent the hanging beam 107 from falling. At the same time, the first driving motor 102 is not required to always output torque.

[0090] In one feasible embodiment, as shown in FIG3 , a reverse hook 119 is designed on the side of the shaft of the first winch 105, and the first lifting rope 106 is knotted to form a loop and hooked to the hook. The first lifting rope 106 is not easily detached when retracted. In the event of an abnormality, the first lifting rope 106 is released to its maximum limit and automatically detached, and the portion below the lifting beam 107 is completely discarded.

[0091] Furthermore, a proximity switch (not shown) is provided on the first frame 101 near the first winch 105. The proximity switch detects the hollow signal of the first winch 105, determines the rotation angle of the first winch 105, and realizes a double closed loop with the motor encoder of the first drive motor 102 to set the extreme position of the first suspension rope 106.

[0092] Example 2

[0093] 10 to 12 , in this embodiment, the driving unit 100 includes a second frame 112 , which serves as a mounting frame and provides a mounting base for the various components. The driving unit 100 also includes a second driving assembly, a second winch 116 , a second lifting rope 117 , and a power switching device 118 . The second driving assembly includes a second driving motor 113 , a second transmission gear set 114 , and a second transmission shaft 115 , wherein:

[0094] The output end of the second drive motor 113 is connected to the second transmission shaft 115 through the second transmission gear set 114. The second drive motor 113 has current detection and feedback of load changes. The landing feedback of the preset target body 300 is realized through load current detection. The second transmission gear set 114 includes a plurality of meshing gears to transmit the driving force of the second drive motor 113 to the second transmission shaft 115, driving the second transmission shaft 115 to rotate with its own axis as the center line. The number and distribution of gears in the second transmission gear set 114 can be determined according to actual needs.

[0095] Multiple second winches 116 are all idle on the second transmission shaft 115, and multiple second lifting ropes 117 and multiple mounting parts 200 correspond one-to-one to the multiple second winches 116. One end of the second lifting rope 117 is wrapped around the second winch 116, and the other end of the second lifting rope 117 is connected to the mounting part 200. When the second winch 116 is idle, although the second drive motor 113 can drive the second transmission shaft 115 to rotate, it cannot transmit torque to the second winch 116.

[0096] The second frame 112 is provided with a plurality of guide wheels and tension wheels to form an arrangement path for the second suspension rope 117. The retraction and extension process of the second suspension rope 117 is structurally guided so that the second suspension rope 117 will not be caught by spatial obstacles such as tree branches during the rising or descending process when there is no load.

[0097] The power switching device 118 is used to keep the preset second winch 116 and the second transmission shaft 115 rotating synchronously, so that the corresponding second winch 116 and the second transmission shaft 115 keep rotating synchronously. The second lifting rope 117 on the single or multiple second winches 116 is retracted and released, causing the corresponding load-bearing part to rise and fall, while the other second winches 116 do not rotate with the second transmission shaft 115, so that the other load-bearing parts will not rise or fall.

[0098] When the mounting portion 200 needs to mount a preset target 300, the power switching device 118 locks one of the second winches 116 on the second transmission shaft 115, and the second drive motor 113 works. The driving force is transmitted to the second transmission shaft 115 via the second transmission gear set 114. The rotation of the second transmission shaft 115 drives the second winch 116 to rotate synchronously, thereby driving the corresponding mounting portion 200 to rise and fall, while the other mounting portions 200 can remain stationary. The lowered mounting portion 200 mounts the corresponding preset target. After the target body 300 is unloaded, the second driving motor 113 drives the second lifting rope 117 to retract and raise the mounting part 200, and so on, so that one or more mounting parts 200 are mounted with the preset target body 300. After the drone arrives at a destination, the second driving motor 113 will lower the mounting parts 200 that need to unload the preset target body 300 in batches. After the mounting part 200 unloads the preset target body 300 that has arrived at this destination, the drone arrives at the next destination and unloads other corresponding preset target bodies 300.

[0099] In this embodiment, referring to FIG. 13 and FIG. 14 , the mounting portion 200 includes a second guide slide 210 , a second locking paddle 212 , a locking seat 213 , a locking rod 215 , and a locking clamp 216 , wherein:

[0100] The second guide slide 210 is used to guide the movement of the preset target 300. The second guide slide 210 is arranged at an angle relative to the direction of gravity. When the preset target 300 is assembled, the second guide slide 210 is inserted into the hanging groove 302 of the handle 301, and the handle 301 climbs upward along the second guide slide 210. When the preset target 300 is unloaded, the second guide slide 210 is arranged at an angle. Therefore, due to the deadweight of the preset target 300, the handle 301 slides down the second guide slide 210, and the preset target 300 is separated from the mounting portion 200.

[0101] The second locking paddle 212 is rotatably arranged on the moving path of the preset target body 300. Specifically, a second mounting slot 211 is penetrated on the second guide slide 210, and the second locking paddle 212 is pivotally connected to the second mounting slot 211. The second locking paddle 212 includes a second front paddle 2121 and a second rear paddle 2122. A second locking space 2123 is formed between the second front paddle 2121 and the second rear paddle 2122. The second locking space 2123 forms a "V"-shaped structure. The second front paddle 2121 and the second rear paddle 2122 constitute two sides of the "V"-shaped structure. Under normal circumstances, the second front paddle 2121 is located above the first mounting slot 2011, and the second rear paddle 2122 is accommodated in the second mounting slot 211.

[0102] The locking seat 213 is connected to the second guide slide 210 as a whole, and the locking rod 215 can be elastically arranged in the locking seat 213. In a feasible embodiment, a second accommodating chamber (not shown) is provided in the locking seat 213, and a second spring 214 is provided in the second accommodating chamber. The locking rod 215 is accommodated in the second accommodating chamber and abuts against the second spring 214. The other end of the second spring 214 abuts against the inner wall of the second accommodating chamber. The first end of the locking rod 215 is connected to the second suspension rope 117, and the second end of the locking rod 215 is connected to the first end of the locking card 216. The plate body of the locking card 216 is rotatably arranged in the locking seat 213, and the second rear paddle 2122 is located in the rotation path of the second end of the locking card 216, and the second end of the locking card 216 forms a bending structure.

[0103] When the handle 301 of the preset target body 300 moves along the second guide slide 210, it first abuts against the second front paddle 2121. As the preset target body 300 moves, it pushes the second locking paddle 212 to rotate, and the second rear paddle 2122 will rotate to the top of the second guide slide 210, and the handle 301 falls into the second locking space 2123.

[0104] At this time, the support for the weight of the preset target object 300 is released, allowing the second hanging rope 117 to bear the load at the bottom alone. Under the tension of the second hanging rope 117, the locking rod 215 moves upward and compresses the second spring 214. The second spring 214 accumulates elastic restoring force, and the paddle card rotates under the lifting of the locking rod 215. The end of the locking card 216 clamps the second rear paddle 2122 to prevent the movable paddle from rotating and opening instantly. At this time, the mounting part 200 is in the first posture, and the preset target object 300 is locked in the second locking space 2123 to achieve stable mounting.

[0105] When the preset target body 300 needs to be unloaded, the second lifting rope 117 is lowered. During the descent, the preset target body 300 slowly contacts the supporting place. At this time, due to the elastic restoring force of the second spring 214, the locking rod 215 moves downward, driving the paddle card to rotate in the opposite direction. The paddle card moves away from the second rear paddle and disengages from the second rear paddle. At this time, when the mounting part 200 is in the second posture, the preset target body 300 continues to move under the action of its own gravity and disengages from the second locking space 2123.

[0106] Furthermore, a plurality of third driving members 217 are provided on the second frame 112, and the plurality of third driving members 217 are arranged corresponding to the plurality of locking seats 213. The end of the third driving member 217 is connected to the second positioning pin 110, and the third driving member 217 can drive the second positioning pin 110 to move back and forth to achieve locking of the locking rod 215.

[0107] In this embodiment, referring to FIG. 11 and FIG. 12 , the power switching device 118 includes a connecting rod 1181 , a fourth driving member 1182 , a shift fork 1183 , a first spline 1184 , and a second spline 1185 , wherein:

[0108] The fourth driving member 1182 is connected to the connecting rod 1181 to drive the connecting rod 1181 to move back and forth along the axial direction of the second transmission shaft 115. In a feasible implementation, the fourth driving member 1182 is a servo, and the connecting rod 1181 is connected to the output end of the servo. The extension direction of the connecting rod 1181 is parallel to the extension direction of the second transmission shaft 115. The output end of the servo swings to drive the connecting rod 1181 to move linearly. Those skilled in the art can know that the fourth driving member 1182 can also be a screw motor or a driving cylinder, etc., which is not limited here.

[0109] The number of first splines 1184 and second splines 1185 matches the number of second capstans 116. Each second capstan 116 corresponds to a first spline 1184 and a second spline 1185. The first spline 1184 is fixed on the second transmission shaft 115. The second spline 1185 is arranged at the end of the second capstan 116 and is loosely sleeved on the second transmission shaft 115. The second splines 1185 are adjacent to the corresponding first splines 1184. The axial length of each second spline 1185 is different. In a feasible implementation manner, the length of each second spline 1185 increases successively along the axial direction of the second transmission shaft 115.

[0110] The number of shift forks 1183 also matches the number of second capstans 116, with each second capstan 116 correspondingly matched with a shift fork 1183. The first end of the shift fork 1183 is fixed to the connecting rod 1181, and the second end of the shift fork 1183 is provided with a spline sleeve 1186, which is keyed to the first spline 1184 and / or the second spline 1185. When the spline sleeve 1186 is keyed to only the first spline 1184 or the second spline 1185, the corresponding second capstan 116 is loosely mounted on the second transmission shaft 115. When the spline sleeve 1186 is keyed to both the first spline 1184 and the second spline 1185, the corresponding second capstan 116 rotates synchronously with the second transmission shaft 115.

[0111] Furthermore, a blocking block 1187 is provided on the fork 1183, a notch 1188 is provided on the blocking block 1187, and a tooth-shaped protrusion 1161 is provided on the outer peripheral surface of the second capstan 116. When the spline sleeve 1186 is only bonded to the first spline 1184 or the second spline 1185, the corresponding tooth-shaped protrusion 1161 on the second capstan 116 corresponds to the blocking block 1187, thereby blocking the second capstan 116 from rotating; when the spline sleeve 1186 is simultaneously bonded to the first spline 1184 and the second spline 1185, the corresponding tooth-shaped protrusion 1161 on the second capstan 116 corresponds to the notch 1188, and the second capstan 116 rotates normally.

[0112] In a feasible embodiment, three second capstans 116 are provided on the second transmission shaft 115, and a second spline 1185 is provided at the end of each second capstan 116. The second transmission shaft 115 is provided with a first spline 1184 corresponding to the axial direction of the second spline 1185. In the initial state, each spline sleeve 1186 is only bonded to each first spline 1184 or second spline 1185, and the blocking block 1187 on each fork 1183 corresponds to the toothed protrusion 1161 on the corresponding second capstan 116, blocking the rotation of the second capstan 116. At this time, after the second transmission shaft 115 rotates, the three second capstans 116 do not rotate accordingly.

[0113] The fourth driving member 1182 drives the connecting rod 1181 to move, thereby driving the entire shift fork to move to the first position. At this time, the leftmost shift fork drives the spline sleeve 1186 to simultaneously key the corresponding second spline 1185 and the first spline 1184. At the same time, the notch 1188 on the blocking block 1187 on the leftmost shift fork 1183 corresponds to the tooth-shaped protrusion 1161, avoiding interference with the rotation of the second capstan 116. The remaining two spline sleeves 1186 are still only keyed to the first spline 1184 or the second spline 1185. The blocking blocks 1187 on the corresponding shift fork 1183 correspond to the tooth-shaped protrusions 1161 on the two second capstans 116, blocking the rotation of the second capstan 116. At this time, the second transmission shaft 115 rotates to drive the first spline 1184, and the spline sleeve 1186 transmits the rotation to the leftmost second capstan 116, realizing the rotation function of the leftmost second capstan 116.

[0114] The fourth driving member 1182 continues to drive the shift fork to move rightward to the second position via the connecting rod 1181. By the same principle, the power connection of the middle second capstan 116 is realized, and the positions of the left and right second capstans 116 are locked.

[0115] The fourth driving member 1182 continues to drive the shift fork to move rightward to the third position through the connecting rod 1181. The same principle is used to achieve power connection on the rightmost side and lock the position of the second capstan 116 on the left and middle sides.

[0116] The above describes in detail the structure, features and effects of the present disclosure based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present disclosure, but the present disclosure is not limited to the scope of implementation by the drawings.
