[0035] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0036] Please refer to the following Figure 1-8 A quick coupling device 100 according to an embodiment of the present invention is described.

[0037] Reference Figure 1 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7 The quick coupling device 100 according to an embodiment of the present invention is used to connect a first structural member and a second structural member, and includes: a first connecting member 10, a second connecting member 20, a fixing member 30, a locking member 40 and a pushing member 50.

[0038] Specifically, the first connecting member 10 is suitable for connecting the first structural member; the second connecting member 20 is suitable for connecting the second structural member, and is connected to the first connecting member 10 in the first direction (such as Figure 3The fixing member 30 is provided between the first connecting member 10 and the second connecting member 20 and is fixed to the first connecting member 10; the locking member 40 is provided on the fixing member 30 and is movable relative to the fixing member 30 between a locked position and an unlocked position. In the locked position, the locking member 40 is connected between the fixing member 30 and the second connecting member 20 so that the fixing member 30 and the second connecting member 20 are relatively fixed. In the unlocked position, the locking member 40 is disengaged from the second connecting member 20 so that the fixing member 30 and the second connecting member 20 are separable. The pushing member 50 is used to push the locking member 40 to move between the unlocked position and the locked position.

[0039] For example, Figure 1 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, the first connecting member 10 and the second connecting member 20 are arranged at intervals in the left-right direction, the first connecting member 10 is provided on the left side of the second connecting member 20, the first structural member may be a robotic arm, the second structural member may be a robotic hand, the first structural member may be connected to the first connecting member 10, the second structural member may be connected to the second connecting member 20, the fixing member 30 is provided between the first connecting member 10 and the second connecting member 20, and is fixed to the first connecting member 10, and the locking member 40 may be sleeved on the fixing member 30. Preferably, the fixing member 30 may be screwed to the first connecting member 10 by bolts, or the fixing member 30 may be snap-connected to the first connecting member 10, so that the fixing member 30 can be easily installed with the first connecting member 10, and repaired and replaced.

[0040] When using the quick connection device 100 to connect the first structural member and the second structural member, first rotate the pushing member 50, for example, rotate the pushing member 50 counterclockwise, so that the pushing member 50 no longer limits the locking member 40 to the locked position, then connect the second connecting member 20 to the fixing member 30, and the second connecting member 20 pushes the locking member 40 to the unlocked position, then rotate the pushing member 50, for example, rotate the pushing member 50 clockwise, and the pushing member 50 pushes the locking member 40 from the unlocked position to the locked position. At this time, the second connecting member 20 is fixedly connected to the fixing member 30 through the locking member 40, and finally the first structural member is connected to the first connecting member 10, and the second structural member is connected to the second connecting member 20, so as to realize the rigid connection between the first structural member and the second structural member through the quick connection device 100.

[0041] If it is necessary to separate the first structural member from the second structural member, rotate the pushing member 50 counterclockwise so that the pushing member 50 no longer limits the locking member 40 to the locked position, and then separate the second connecting member 20 from the fixing member 30. During the separation process of the second connecting member 20 from the fixing member 30, the locking member 40 is pushed to the unlocked position, and then the first structural member is separated from the first connecting member 10, and the second structural member is separated from the second connecting member 20. At this time, the disassembly and separation of the first structural member and the second structural member are completed.

[0042] The quick-connect device 100 of the present invention is provided with a locking member 40 and a pushing member 50. Through the cooperation of the pushing member 50 and the locking member 40, the locking member 40 can secure the second connecting member 20 to the fixing member 30 in the locked position, thereby enabling rapid connection of the first and second structural members through the quick-connect device. The locking member 40 can separate the second connecting member 20 from the fixing member 30 in the unlocked position, thereby enabling rapid disassembly of the first and second structural members through the quick-connect device. This facilitates connection and disassembly of the first and second structural members through the quick-connect device 100, saving connection and disassembly time and improving efficiency. Furthermore, the quick-connect device 100 can be applied to applications requiring frequent connection and disassembly, such as train carriages and flexible arms. Compared to prior art solutions in which the first and second structural members are connected by bolts, which require frequent installation and removal of bolts, the quick-connect device 100 of the present invention can connect and disconnect the first and second structural members simply by the pushing member 50 pushing the locking member 40, thereby reducing operational difficulty and improving connection and disassembly efficiency.

[0043] Furthermore, the first structural member and the second structural member are connected by the quick connection device 100, the locking member 40 is in the locking position, the second connecting member 20 is fixedly connected to the fixing member 30, and the fixing member 30 is fixedly connected to the first connecting member 10, so that the second connecting member 20 and the first connecting member 10 can be fixedly connected, thereby ensuring that the first structural member and the second structural member are rigidly connected, and the first structural member can transmit the force to the second structural member through the quick connection device 100, thereby ensuring that the first structural member and the second structural member can work normally, thereby improving the versatility of the quick connection device 100.

[0044] According to the quick connection device 100 of the embodiment of the present invention, a locking member 40 and a pushing member 50 are provided. Through the cooperation between the pushing member 50 and the locking member 40, the first structural member and the second structural member can be quickly disassembled through the quick connection device, thereby saving the time of connection and disassembly and improving efficiency. At the same time, the first structural member and the second structural member can be rigidly connected, thereby ensuring the rigidity between the first structural member and the second structural member, thereby improving the versatility of the quick connection device 100.

[0045] According to some embodiments of the present invention, referring to Figure 2 、 Figure 3 and Figure 7 The first structural member is provided with a first connector, and the second structural member is provided with a second connector. The first connector 10 is provided with a pin assembly 11 adapted to be plugged into the first connector. The second connector 20 is provided with a through hole 21 corresponding to the pin assembly 11. The pin assembly 11 passes through the through hole 21 and is adapted to be plugged into the second connector of the second structural member. Thus, the first structural member can be electrically connected to the second structural member via the pin assembly 11. While ensuring a rigid connection between the first and second structural members, signal transmission between the first and second structural members can also be guaranteed. This allows the quick-connect device 100 to be applied in a variety of fields, such as flexible support arms.

[0046] For example, Figure 2 、 Figure 3 and Figure 7 As shown, the first structural member is provided with a first plug connector, and the first connector 10 is provided with a pin assembly 11. One end of the pin assembly 11 is exposed from the first connector 10 and faces the surface of the first connector 10, facilitating insertion of the first plug connector. The second connector 20 is provided with a through hole 21 corresponding to the pin assembly 11. The pin assembly 11 passes through the through hole 21 and is plugged into the second connector. Preferably, the pin assembly 11 has multiple pins, some of which can achieve electrical connection between the first structural member and the second structural member, and some of which can achieve connection and positioning between the first structural member and the second structural member.

[0047] According to some optional embodiments of the present invention, referring to Figure 3 、 Figure 4 and Figure 7 The fixing member 30 includes a fixing ring 31, which is sleeved on the second connecting member 20. The fixing ring 31 is provided with a fixing hole 311 that penetrates the fixing ring 31 along the radial direction of the fixing ring 31. The locking member 40 is provided in the fixing hole 311 and moves between a locking position and an unlocking position along the radial direction of the fixing ring 31. The second connecting member 20 is provided with a groove 22 corresponding to the fixing hole 311 along the radial direction of the fixing ring 31. When the locking member 40 is in the locking position, the locking member 40 is located in the fixing hole 311 and the groove 22. When the locking member 40 is in the unlocking position, the locking member 40 exits the groove 22.

[0048] In this way, the structure of the fixing ring 31 is reasonable, thereby facilitating the connection between the fixing ring 31 and the second connecting member 20. At the same time, it ensures that the pushing member 50 can rotate relative to the fixing ring 31, thereby enabling the pushing member 50 to push the locking member 40 between the unlocked position and the locked position. Furthermore, this structural form of the fixing member 30 is simple and easy to process, and it also facilitates the arrangement of the fixing hole 311. In addition, the locking member 40 cooperates with the fixing hole 311 and the groove 22 to achieve locking between the fixing member 30 and the second connecting member 20 in the first direction. This fixing form is simple and easy to operate, thereby improving the connection efficiency of the first structural member and the second structural member via the quick connection device 100.

[0049] For example, Figure 3 、 Figure 4 and Figure 7 As shown, the fixing ring 31 is formed into a circular ring shape, and the fixing ring 31 is sleeved on the second connecting member 20. The fixing hole 311 passes through the fixing ring 31 along the radial direction of the fixing ring 31. The locking member 40 is arranged in the fixing hole 311. The second connecting member 20 is provided with a groove 22 that is recessed inward along the radial direction of the fixing ring 31. The groove 22 corresponds to the fixing hole 311 in the radial direction of the fixing ring 31.

[0050] When using the quick coupling device 100, when the locking member 40 is in the locked position, part of the locking member 40 is located in the fixing hole 311, and part of the locking member 40 is located in the groove 22. At this time, the second connecting member 20 can be fixed to the fixing member 30. When the locking member 40 moves from the locked position to the unlocked position, the locking member 40 exits the groove 22 radially outward along the fixing ring 31, so that the entire locking member 40 is located in the fixing hole 311. At this time, the second connecting member 20 can be separated from the fixing member 30.

[0051] According to some embodiments of the present invention, referring to Figure 3 Figure 4 and Figure 7 The number of fixing holes 311 is multiple, that is, the number of fixing holes 311 can be two, three, or four or more, and the multiple fixing holes 311 are spaced apart along the circumference of the fixing ring 31. The number of grooves 22 is multiple, that is, the number of grooves 22 can be two, three, or four or more. The number of locking members 40 is multiple, that is, the number of locking members 40 can be two, three, or four or more, and the grooves 22, locking members 40, and fixing holes 311 correspond one-to-one. Thus, the multiple grooves 22, the multiple locking members 40, and the multiple fixing holes 311 correspond one-to-one and cooperate with each other. When the locking member 40 locks the fixing member 30 and the second connecting member 20, the fixing strength of the fixing member 30 and the second connecting member 20 can be guaranteed, thereby ensuring the connection strength between the first structural member and the second structural member, and effectively preventing the first structural member from separating from the second structural member.

[0052] For example, Figure 3 Figure 4 and Figure 7 As shown, there are four fixing holes 311 , which are arranged at intervals along the circumference of the fixing ring 31 . There are four grooves 22 and four locking members 40 , and the four grooves 22 , the four locking members 40 and the four fixing holes 311 correspond one to one.

[0053] According to some optional embodiments of the present invention, referring to Figure 3 The locking member 40 is spherical. Therefore, the spherical locking member 40 can smoothly cooperate with the fixing hole 311, thereby ensuring that the locking member 40 can normally move between the unlocked position and the locked position in the fixing hole 311. At the same time, the friction force of the locking member 40 moving in the fixing hole 311 can be reduced, thereby ensuring the smooth movement of the locking member 40.

[0054] According to some optional embodiments of the present invention, referring to Figure 3 and Figure 4 In the radial direction of the fixing ring 31, the diameter of the fixing hole 311 at one end facing the groove 22 is smaller than the diameter of the locking member 40. Since the locking member 40 is spherical, when the second connecting member 20 is not connected to the fixing ring 31, the locking member 40 is prevented from directly sliding out of the fixing hole 311 and falling off, thereby preventing the locking member 40 from being lost.

[0055] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 The fixing member 30 includes a fixing plate 32, the fixing plate 32 is perpendicular to the first direction (such as Figure 3 The fixing plate 32 extends along the circumference of the fixing ring 31, and the fixing member 30 is detachably connected to the first connecting member 10 via the fixing plate 32. Thus, the fixing plate 32 provides a connection position for the fixing member 30 to the first connecting member 10, thereby facilitating the connection of the fixing member 30 to the first connecting member 10. Furthermore, the detachable connection between the fixing member 30 and the first connecting member 10 facilitates maintenance and replacement of the fixing member 30 and the first connecting member 10.

[0056] For example, Figure 3 and Figure 4 As shown, the fixing plate 32 is arranged perpendicular to the left-right direction, and the fixing plate 32 extends along the circumference of the fixing ring 31 . The fixing member 30 is screwed to the first connecting member 10 through the fixing plate 32 .

[0057] According to some embodiments of the present invention, referring to Figure 3 、 Figure 4 and Figure 6The pushing member 50 is annular and is sleeved on the fixing ring 31. It can rotate relative to the fixing ring 31 between a first position and a second position. A pushing surface 51 is formed on the inner wall of the pushing member 50. The pushing surface 51 has a first end 511 and a second end 512 that are arranged opposite to each other in the circumferential direction of the pushing member 50. In the direction from the first end 511 to the second end 512, the pushing surface 51 extends along an arc that gradually approaches the center of the pushing member 50. When the pushing member 50 is in the first position, the first end 511 abuts against the locking member 40 in the radial direction of the pushing member 50. When the pushing member 50 is in the second position, the second end 512 abuts against the locking member 40 in the radial direction of the pushing member 50. When the pushing member 50 rotates from the first position to the second position, it pushes the locking member 40 to move from the unlocked position to the locked position.

[0058] Thus, the pusher 50 has a reasonable structure, ensuring that it can normally push the locking member 40 from the unlocked position to the locked position. Furthermore, the pusher 50 is sleeved on the fixing ring 31, which can reduce the length of the quick-connect device 100 in the first direction, thereby reducing the volume of the quick-connect device 100. Furthermore, the pusher surface 51 is reasonably positioned so that when the pusher 50 rotates, it can directly contact the locking member 40 through the pusher surface 51, thereby ensuring that the pusher 50 can push the locking member 40 to move. Furthermore, the pusher surface 51 extends in a reasonable manner, so that as the pusher 50 rotates, it can push the locking member 40 to move.

[0059] For example, Figure 3 、 Figure 4 and Figure 6 As shown, the pusher 50 is annular and is sleeved on the fixing ring 31. The inner wall of the pusher 50 is formed with a push surface 51. The push surface 51 has a first end 511 and a second end 512 arranged opposite each other in the circumferential direction of the pusher 50. In the direction from the first end 511 to the second end 512, the push surface 51 extends along an arc that gradually approaches the center of the pusher 50, that is, the push surface 51 forms a progressive compression curve. In the first position of the pusher 50, the first end 511 abuts the locking member 40 in the radial direction of the pusher 50, and the locking member 40 is in the unlocked position. In the second position of the pusher 50, the second end 512 abuts the locking member 40 in the radial direction of the pusher 50, and the locking member 40 is in the locked position. Preferably, a push surface 51 can be divided into multiple sections to facilitate the processing of the push surface 51.

[0060] When the pushing member 50 is in the first position, the first end 511 abuts against the locking member 40 in the radial direction of the pushing member 50, and the locking member 40 is in the unlocked position. When the pushing member 50 is pushed to rotate relative to the fixing ring 31, the position where the pushing surface 51 abuts against the locking member 40 gradually moves from the first end 511 to the second end 512. Since the second end 512 is closer to the circular distance from the pushing member 50, the pushing surface 51 pushes the locking member 40 to move radially inward along the fixing ring 31 until part of the locking member 40 is located in the fixing hole 311 and part of it is located in the groove 22, thereby realizing the locking of the fixing member 30 and the second connecting member 20.

[0061] According to some embodiments of the present invention, referring to Figure 3 、 Figure 4 and Figure 6 The number of the pushing surfaces 51 is multiple, that is, the number of the pushing surfaces 51 can be two, three, or four or more, and the multiple pushing surfaces 51 are arranged at intervals along the circumference of the pushing member 50. The number of the locking members 40 is multiple, that is, the number of the locking members 40 can be two, three, or four or more, and the pushing surfaces 51 correspond one-to-one with the locking members 40. As a result, the multiple pushing surfaces 51 correspond one-to-one with the multiple locking members 40, thereby ensuring that each locking member 40 can be moved to the locked position by the corresponding pushing surface 51. Therefore, when the fixing member 30 is fixedly connected to the second connecting member 20, it can be ensured that each locking member 40 can effectively lock the fixing member 30 and the second connecting member 20, thereby ensuring the fixing strength of the fixing member 30 and the second connecting member 20.

[0062] For example, Figure 3 、 Figure 4 and Figure 6 As shown, there are four pushing surfaces 51 , which are arranged at intervals along the circumference of the pushing member 50 , and the pushing surfaces 51 correspond to the locking members 40 one by one.

[0063] According to some embodiments of the present invention, referring to Figure 3 and Figure 6 The radial outer surface of the pusher 50 is provided with a toggle portion 52, which is used to toggle the pusher 50 to rotate. Thus, the toggle portion 52 can provide a point of action, thereby making it easy to toggle the pusher 50.

[0064] For example, Figure 3 and Figure 6 A toggle portion 52 is provided on the radial outer surface of the push member 50 . The toggle portion 52 extends away from the push member 50 in the radial direction of the push member 50 and extends in the left and right directions of the push member 50 into a long strip shape.

[0065] According to some optional embodiments of the present invention, referring to Figure 2 and Figure 3, the first connecting member 10 faces the side of the second connecting member 20 (such as Figure 3 The right side surface of the first connecting member 10 shown is provided with a first limiting column 12 and a second limiting column 13, and the toggle portion 52 is provided between the first limiting column 12 and the second limiting column 13. When the pushing member 50 is in the first position, the toggle portion 52 abuts against the first limiting column 12, and when the pushing member 50 is in the second position, the toggle portion 52 abuts against the second limiting column 13.

[0066] In this way, the first limit column 12 and the second limit column 13 are set, and the rotation stroke of the pushing member 50 can be effectively limited while ensuring that the pushing member 50 can normally push the locking member 40 to move between the locking position and the unlocking position, thereby preventing the pushing member 50 from rotating without restriction, causing the fitting pressure between the locking member 40 and the fixing member 30 and the second connecting member 20 to be too large, resulting in damage to the quick connection device 100, and thus effectively protecting the quick connection device 100.

[0067] For example, Figure 2 and Figure 3 A first limiting column 12 and a second limiting column 13 are provided on the right side of the first connecting member 10. When the pushing member 50 is in the first position, the toggle portion 52 abuts against the first limiting column 12. When the pushing member 50 is in the second position, the toggle portion 52 abuts against the second limiting column 13.

[0068] Furthermore, if Figure 2 and Figure 3 As shown, threaded holes are provided in the first limiting column 12 and the second limiting column 13, and through holes corresponding to the first limiting column 12 and the second limiting column 13 are provided on the fixing plate 32. After the first limiting column 12 and the second limiting column 13 pass through the corresponding through holes, the first connecting member 10 and the fixing member 30 can be fixed by the bolts matching the threads in the threaded holes.

[0069] According to some optional embodiments of the present invention, referring to Figure 2 and Figure 3 The quick-connect device 100 includes an elastic member 60 connected between the first connector 10 and the pusher 50. The elastic member 60 constantly pushes the pusher 50 to rotate from the first position toward the second position. Thus, the locking member 40 is normally in the locked position. After the second connector 20 is separated from the fixing member 30, the elastic member 60 pushes the pusher 50 to rotate from the first position toward the second position, causing the locking member 40 to move from the unlocked position to the locked position, thereby automatically resetting the locking member 40.

[0070] Preferably, the elastic member 60 may be a torsion spring, a tension spring or the like, which has a simple structure, low cost, and is convenient for mass use. Alternatively, the elastic member 60 may be directly replaced by a motor.

[0071] According to some optional embodiments of the present invention, referring to Figure 2 and Figure 3 , the first connecting member 10 faces the side of the second connecting member 20 (such as Figure 3 A fixing post 14 is provided on the right side of the first connecting member 10 (shown). The elastic member 60 is a coiled elastic member that is sleeved onto the fixing post 14. One end of the coiled elastic member is fixedly connected to the pusher 50. Thus, the coiled elastic member ensures that the elastic member 60 always pushes the pusher 50 from the first position toward the second position. Furthermore, the coiled elastic member has a simple structure and is easy to process, thereby facilitating the production of the elastic member 60 and facilitating mass production.

[0072] For example, Figure 2 and Figure 3 As shown, the winding elastic member is sleeved on the fixing column 14 , and a screw hole is provided at one end of the winding elastic member. A bolt passes through the screw hole and is fixedly connected to the pushing member 50 .

[0073] Furthermore, if Figure 2 and Figure 3 As shown, a threaded hole is provided in the fixing column 14, and a through hole corresponding to the fixing column 14 is provided on the fixing plate 32. After the fixing column 14 passes through the corresponding through hole, the fixing strength of the first connecting member 10 and the fixing member 30 can be further strengthened by the bolt engaging with the thread in the threaded hole.

[0074] Below, refer to the attached Figure 1-8 The steps for using the quick coupling device 100 are described in detail.

[0075] Under normal conditions, the winding elastic member always pushes the pusher 50 to the second position. The toggle portion 52 of the pusher 50 abuts the second limiting post 13. The pusher 50 abuts the locking member 40 through the second end 512 of the pushing surface 51, and the locking member 40 is pushed to the locked position. After the first connector of the first structural member is plugged into the pin assembly 11, the toggle portion 52 is pushed counterclockwise to rotate from the second limiting post 13 until the toggle portion 52 abuts the first limiting post 12. At this time, the second connecting member 20 is inserted into the fixing ring 31, and the pin assembly 11 is inserted into the second connector of the second structural member through the insertion hole, completing the electrical connection between the first and second structural members. The toggle portion 52 is then released, and the winding elastic member pulls the pusher 50 from the first position to the second position until the toggle portion 52 abuts the second limiting post 13 again, and the pusher 50 rotates to the second position.

[0076] During the process of the pushing member 50 rotating from the first position to the second position, the locking member 40 is first in the unlocked position, the pushing member 50 is in the first position, and the first end 511 of the pushing surface 51 abuts against the locking member 40. As the pushing member 50 rotates, the pushing surface 51 gradually pushes the locking member 40 to move radially inward along the fixing ring 31 until part of the locking member 40 is located in the fixing hole 311 and part of it is located in the groove 22. The second end 512 of the pushing surface 51 abuts against the locking member 40, and the pushing member 50 is in the second position. At this time, the first structural member and the second structural member are rigidly connected through the quick connection device 100.

[0077] If it is necessary to separate the first structural member from the second structural member, repeat the above steps in reverse. After the second connecting member 20 pushes the locking member 40 back from the groove 22 into the fixing hole 311, the second connecting member 20 can be separated from the fixing member 30. Then, the first structural member is separated from the first connecting member 10, and the second structural member is separated from the second connecting member 20 in turn. At this time, the separation of the first structural member and the second structural member is completed.
