Abstract
Description
Technical Field
[0001] This invention relates to the field of electrical connection devices, and in particular to a quick docking device. Background Technology
[0002] Quick-connect devices typically include a plug and a socket. The socket has at least one electrical connection wire that can be connected to various wires, facilitating connection to other circuits. The plug can be inserted into the socket to connect to it.
[0003] The plugs and sockets of existing quick-connect devices require manual visual calibration before insertion, which is inefficient. Furthermore, since the installation positions of the plugs and sockets are usually concealed, it is not easy for users to observe whether the two are fully aligned when they hold the plug and insert it into the socket. If the plug and socket are not fully aligned, the plug is prone to mis-insertion and incorrect insertion. Moreover, the plug is also prone to falling out of the socket. Summary of the Invention
[0004] Based on this, the present invention provides a rapid docking device to address the above-mentioned technical problems.
[0005] A quick-connection device includes a plug and a socket, wherein the plug and the socket are plugged into each other; one of the plug and the socket has a protrusion, and the other has a groove, wherein the protrusion can engage with the groove as the plug moves; wherein one of the plug and the socket also has a positioning element, and the other has a positioning groove, wherein the positioning element can elastically abut against the plug or the socket; the positioning element is elastically abutted during the plug-in engagement process, and after the plug rotates around its own axis by a preset angle, the positioning element can elastically return to its original position and lock into the positioning groove, while the protrusion engages with the groove as the plug rotates.
[0006] With this design, the positioning element can elastically abut against the plug or socket. When the positioning element abuts against the plug or socket, it indicates that there is interference between them, meaning that the plug has not been rotated to the specified angle. In this case, the plug cannot be inserted into the socket, avoiding the situation where the user accidentally inserts the plug into the wrong socket due to objective factors such as lack of focus. When the positioning element enters the positioning groove, it means that the plug has been rotated to the preset angle. At this time, the limiting cooperation between the groove and the protrusion can restrict the movement of the protrusion along the axis of the plug or socket, thereby ensuring that the plug will not come out of the socket.
[0007] In one embodiment, the groove includes a plug-in section and a limiting section, the limiting section being in communication with the plug-in section and extending along the circumference of the plug, the protrusion being able to form a plug-in engagement with the plug-in section as the plug moves, and the protrusion being able to move from the plug-in section into the limiting section as the plug rotates to form a limiting engagement with the limiting section.
[0008] With this configuration, the plug section is used to allow the protrusion to enter the groove. Since the plug section and the limiting section are connected, as the plug rotates, the protrusion can enter the limiting section from the plug section and be stopped by the limiting section, thus preventing it from moving along the axial direction of the plug and preventing the plug from falling out of the socket.
[0009] In one embodiment, the plug has a through hole in the groove wall facing the socket, and the positioning member passes through the through hole. The positioning member is movable along the axis of the through hole to exit the positioning groove.
[0010] This design allows for free adjustment of the protrusion length of the positioning element by its movement, facilitating the engagement between the positioning element and the positioning groove, and enabling their positioning or disengagement. The perforation restricts the movement path of the positioning element, causing it to extend or retract in a single direction.
[0011] In one embodiment, the positioning element includes an expanding section and a reducing section, the expanding section and the reducing section are connected, the diameter of the expanding section is larger than that of the reducing section to form a step, and an elastic element is sleeved on the outer periphery of the reducing section, one end of the elastic element abuts against the step, and the other end abuts against and is fixed to the through hole.
[0012] With this configuration, the elastic element is fitted onto the outer periphery of the reduced-diameter section. Therefore, the reduced-diameter section can guide the elongation and shortening of the elastic element, ensuring that the direction of the elastic force generated is always along the axial direction of the reduced-diameter section. A step is formed between the expanded-diameter section and the reduced-diameter section, which provides a contact surface for the elastic element to abut, increasing the contact area and making the abutment effect of the elastic element on the positioning element more stable. One end of the elastic element abuts against the step, and the other end abuts against and is fixed to the through hole. Because the elastic element always provides the step, which is also providing the positioning element, with an elastic force towards the socket, when the user holds the plug and inserts it towards the socket, if the positioning element is not initially aligned with the positioning groove, the positioning element will first abut against the side of the socket facing the plug, and due to the elastic force of the elastic element, it will always have a tendency to move towards the socket. As the user rotates the plug, when the positioning element is aligned with the positioning groove, the elastic element can make the positioning element quickly enter the positioning groove, thereby realizing the mutual limiting of the positioning element and the positioning groove.
[0013] In one embodiment, the plug has a receiving groove on its circumferential outer side, the receiving groove communicating with the through hole, at least one end of the positioning member is located in the receiving groove, the plug also includes a movable plate, the movable plate including a movable section and a connecting section, the movable section covering the opening of the receiving groove, the connecting section extending into the receiving groove, and the positioning member connected to the connecting section.
[0014] This configuration provides space for the connecting section to move within the receiving slot, allowing the connecting section to move the positioning component. The moving section is located outside the opening of the receiving slot, facilitating user operation. Since the moving section is connected to the connecting section, and the connecting section is connected to the positioning component, the moving section can move the positioning component. The user can operate the moving plate to remove the positioning component from the positioning slot, thereby releasing the positioning slot from its restriction on the positioning component. This allows the plug to be pulled out of the socket. Furthermore, due to the elastic potential energy accumulated in the elastic element, when the positioning component is no longer resisted by the socket, i.e., when the positioning component can enter the positioning slot, the elastic potential energy of the elastic element is released and converted into the kinetic energy of the positioning component. The positioning component can then quickly enter the positioning slot and cause the connecting section to impact the wall of the receiving slot, producing a collision sound to indicate to the user that the positioning component has reached the designated position.
[0015] In one embodiment, the socket is provided with a limiting ring, one end of the plug can be inserted into the limiting ring, the inner wall of the limiting ring is provided with a plurality of protrusions at intervals, and the outer periphery of the end of the plug that extends into the limiting ring is provided with a plurality of grooves, each groove corresponding to a plurality of protrusions.
[0016] This design facilitates the placement of the protrusions, allowing them to mate with the grooves in the circumferential direction, increasing the number of limiting force points, and improving connection strength.
[0017] In one embodiment, the plug is provided with a plurality of pins, and the socket is provided with a plurality of holes, each of the pins being able to be inserted into the corresponding hole, and the length of the pins being compressible along the insertion direction.
[0018] This design ensures a tight connection and prevents poor contact when the contact pin is inserted into the socket. As the pin presses against the bottom of the socket, it is compressed, with the top always against the bottom, guaranteeing a secure connection. If the pin is not aligned, it rests against the side of the socket with the socket opening and remains compressed. As the plug rotates, the pin's position changes accordingly. When the plug is rotated to the designated position and the pin aligns with the socket, it automatically springs back and inserts into the socket. This allows users to blindly insert the plug without needing to check the alignment, improving efficiency.
[0019] In one embodiment, the plug includes a plug body and a plug core, the plug core and the plug body being detachably connected, and the contact pin being connected to the plug core.
[0020] This design allows for the replacement of the connector core, which can be replaced with a core with more or fewer pins depending on the work requirements, without having to replace the entire plug. This improves work efficiency and reduces material costs.
[0021] In one embodiment, the plug body has a core-replacing cavity, the core can be accommodated in the core-replacing cavity, the inner wall of the core-replacing cavity is provided with a plurality of locking blocks at intervals, and the outer periphery of the core is provided with a plurality of locking grooves, each of the locking blocks can be locked into the corresponding locking groove.
[0022] This design reduces the space occupied by the ferrule and improves the connection strength between the ferrule and the plug body.
[0023] In one embodiment, the socket further includes a socket body, a pin socket, a circuit board, and terminals. One end of the pin socket is connected to the socket body, and the other end is connected to the circuit board. The terminals are connected to the side of the circuit board facing away from the socket body and are electrically connected to the pin socket through the circuit board.
[0024] This configuration allows multiple pin sockets to connect to the socket body and the terminals simultaneously, eliminating the need for separate connections to the corresponding terminals. This reduces the usual wiring process, saves cable space, and facilitates adjustments to the number of pin sockets, making it easy to replace different types and models of terminals.
[0025] In one embodiment, the socket body has a mounting groove on the side away from the plug, and the circuit board is embedded in the mounting groove.
[0026] This design reduces the space occupied by the circuit board and increases the tightness of the connection between the circuit board and the socket body.
[0027] Compared to existing technologies, this invention provides protrusions and grooves on the plug and socket. The grooves include a insertion section that allows the protrusion to enter, guiding the user to rotate the plug to a preset angle so that the protrusion enters the groove. The positioning member can elastically abut against the plug or socket. When the positioning member abuts against the plug or socket, it indicates that there is interference between them, meaning the plug has not been rotated to the specified angle. In this case, the plug cannot be inserted into the socket, avoiding the situation where the plug is mistakenly inserted into the socket due to objective factors such as lack of concentration. When the positioning member enters the positioning groove, it indicates that the plug has been rotated to the preset angle. At this time, the limiting section can restrict the movement of the protrusion along the axial direction of the plug or socket, thereby ensuring that the plug will not come out of the socket.

[0044] Please refer to the instruction manual appendix. Figures 1-3 The present invention provides a quick docking device 100, which is applied in the field of electrical connection devices and is used for electrical connection of electrical equipment.
[0045] The quick docking device 100 includes a plug 10 and a socket 20, which are plugged into each other. One of the plug 10 and the socket 20 is provided with a protrusion 23, and the other is provided with a groove 16. The protrusion 23 can form a plug-in engagement with the groove as the plug 10 moves.
[0046] Specifically, the groove 16 includes a plug-in section 161 and a limiting section 162. The limiting section 162 communicates with the plug-in section 161 and extends circumferentially along the plug 10. The protrusion 23 can form a plug-in engagement with the plug-in section 161 as the plug 10 moves, and the protrusion 23 can move from the plug-in section 161 into the limiting section 162 as the plug 10 rotates, thereby forming a limiting engagement with the limiting section 162. In this way, the plug-in section 161 allows the protrusion 23 to enter, thereby guiding the user to rotate the plug 10 to a preset angle so that the protrusion 23 enters the groove 16. The limiting section 162 can stop the axial movement of the protrusion 23 and prevent the plug 10 from falling out of the socket 20.
[0047] Of course, it is understandable that in other embodiments, the protrusion 23 and the groove 16 can also achieve a limiting fit by other means, such as setting the insertion volume of the protrusion 23 to be slightly larger than that of the groove 16, so that the protrusion 23 can achieve an interference fit with the groove wall of the groove 16 after entering the groove 16, thereby achieving mutual limiting. The connection between the two is not limited to the cooperation between the protrusion 23 and the insertion section 161 and the limiting section 162.
[0048] One of the plug 10 and the socket 20 is provided with a positioning member 13, and the other has a positioning groove 221 extending along the insertion direction of the plug 10. The positioning member 13 can elastically abut against the plug 10 or the socket 20 to restrict the plug 10 from moving further toward the socket 20. Thus, when the positioning member 13 abuts against the plug 10 or the socket 20, it indicates that there is interference between them, that is, the plug 10 has not been rotated to the specified angle. In this case, the plug 10 cannot be inserted into the socket 20, thus avoiding the situation where the user accidentally inserts the plug 10 into the socket 20 due to objective factors such as lack of concentration.
[0049] During the process of the plug 10 and socket 20 forming a plug-in engagement, the positioning member 13 is elastically abutted. After the plug 10 rotates around its own axis by a preset angle, the positioning member 13 can elastically reset and be inserted into the positioning groove 221. At the same time, the protrusion 23 forms a limiting engagement with the groove 16 as the plug 10 rotates.
[0050] With this configuration, when the positioning member 13 enters the positioning groove 221, it means that the plug 10 has been rotated to the preset angle. At this time, the limiting segment 162 can restrict the movement of the protrusion 23 along the axis of the plug 10 or the socket 20, thereby ensuring that the plug 10 will not come out of the socket 20.
[0051] Preferably, in this embodiment, the positioning member 13 is connected to the plug 10, and the socket 20 is provided with a positioning groove 221, so that the plug 10 can be aligned with the socket 20 and inserted into the socket 20.
[0052] Please see Figure 1 and Figures 5-6 A through hole 112 is provided on the groove wall of the plug 10 facing the socket 20. The positioning member 13 is inserted into the through hole 112 and can move along the axis of the through hole 112 to exit from the positioning groove 221. In this way, the extension length of the positioning member 13 can be freely adjusted by moving the positioning member 13, thereby facilitating the engagement between the positioning member 13 and the positioning groove 221 and realizing the limiting or disengagement of the two. The through hole 112 restricts the movement path of the positioning member 13, causing it to extend or retract in a single direction.
[0053] In other embodiments, the positioning member 13 may also be formed by directly protruding a structure on the plug 10, or by movably connecting a positioning member 13 that can move along the insertion direction of the plug 10 to the circumferential outer periphery of the plug 10, and is not limited to the above-described embodiments.
[0054] Specifically, the positioning element 13 is cylindrical, and the through hole 112 is also correspondingly set as a round hole, so the positioning element 13 can rotate in the through hole 112. During the use of the quick docking device 100, friction and collision are inevitable. Because the positioning element 13 is also easily affected by external forces, it will rotate in the through hole 112. With this setting, the rotation of the positioning element 13 will not affect the realization of the function.
[0055] Further, please see Figure 9 The positioning element 13 includes an expanding section 132 and a reducing section 133, which are connected. The diameter of the expanding section 132 is larger than that of the reducing section 133 to form a step 134. An elastic element 14 is sleeved on the outer periphery of the reducing section 133. One end of the elastic element 14 abuts against the step 134, and the other end abuts against and is fixed to the through hole 112. Thus, the elastic element 14 is fitted onto the outer periphery of the reduced diameter section 133, allowing the reduced diameter section 133 to guide the elongation and shortening of the elastic element 14, ensuring that the direction of the elastic force generated is always along the axial direction of the reduced diameter section 133. A step 134 is formed between the expanded diameter section 132 and the reduced diameter section 133, providing a contact surface for the elastic element 14 to abut, increasing the contact area and making the abutment effect of the elastic element 14 on the positioning element 13 more stable. One end of the elastic element 14 abuts against the step 134, and the other end abuts against and is fixed to the through hole 112. Because the elastic element 14 always provides the step 134, In other words, the positioning member 13 is given a spring force towards the socket 20. When the user holds the plug 10 and inserts it towards the socket 20, if the positioning member 13 is not initially aligned with the positioning groove 221, the positioning member 13 will first abut against the side of the socket 20 facing the plug 10, and due to the spring force of the elastic member 14, it will always have a tendency to move towards the socket 20. As the user rotates the plug 10, when the positioning member 13 is aligned with the positioning groove 221, the elastic member 14 can make the positioning member 13 quickly enter the positioning groove 221, thereby realizing the mutual limiting of the positioning member 13 and the positioning groove 221.
[0056] Understandably, in other embodiments, the positioning member 13 can also achieve its own movement toward the socket 20 through other structures. For example, the reduced diameter section 133 of the positioning member 13 can be replaced with an elastic material. When the reduced diameter section 133 is compressed, it can accumulate elastic potential energy, thereby generating a reverse force on the expanded diameter section 132. This causes the positioning member 13 to quickly enter the positioning groove 221 after the plug 10 rotates to a preset angle. There is no need to add an additional elastic member 14, which reduces the number of parts.
[0057] Furthermore, please see Figure 6 as well as Figure 8The plug 10 has a receiving groove 111 on its outer periphery, which communicates with the through hole 112. At least one end of the positioning member 13 is located in the receiving groove 111. The plug 10 also includes a moving plate 15, which includes a moving section 151 and a connecting section 152. The moving section 151 covers the opening of the receiving groove 111. The connecting section 152 is connected to the side of the moving section 151 facing the positioning member 13 and extends into the receiving groove 111. The positioning member 13 passes through the connecting section 152 and is connected to the connecting section 152. Thus, the receiving groove 111 provides space for the connecting section 152 to move within it, enabling the moving section 151 to drive the positioning member 13 to move. The moving section 151 is located outside the opening of the receiving groove 111, facilitating user operation. Since the moving section 151 is connected to the connecting section 152, and the connecting section 152 is connected to the positioning member 13, the moving section 151 can drive the positioning member 13 to move. The user can operate the moving plate 15 to disengage the positioning member 13 from the positioning groove 221, thereby releasing the positioning groove 221 from the positioning member 13. The limit is set so that the plug 10 can be pulled out of the socket 20. Due to the elastic potential energy accumulated by the elastic member 14, when the positioning member 13 is no longer resisted by the socket 20, that is, when the positioning member 13 can enter the positioning groove 221, the elastic potential energy of the elastic member 14 will be released and converted into the kinetic energy of the positioning member 13. The positioning member 13 can then quickly enter the positioning groove 221 and drive the connecting section 152 to hit the groove wall of the receiving groove 111, thereby generating a collision sound to indicate to the user that the positioning member 13 has reached the designated position.
[0058] The connecting section 152 has a connecting hole 153 for the positioning member 13 to pass through. Specifically, the connecting hole 153 has an internal thread on its wall and the outer circumference of the expanded section 132 of the positioning member 13 has an external thread. Through the cooperation of the internal and external threads, the positioning member 13 and the connecting section 152 are fixedly connected, and it is also convenient to disassemble the two.
[0059] Understandably, in other embodiments, the connecting segment 152 may also be connected to the positioning member 13 by other means, such as welding or gluing, and is not limited to the threaded connection described above.
[0060] The connecting segment 152 is fan-shaped, and the arc length of the connecting segment 152 gradually shortens along the direction away from the moving segment 151 in order to save materials and ensure structural strength.
[0061] The connecting hole 153 is opened on the central axis of the fan shape to ensure that the connection between the moving plate 15 and the positioning member 13 is stable when the moving plate 15 moves, and the two are balanced by forces during the movement.
[0062] The plug 10 includes a plug body 11 and a socket 12. The socket 12 is provided with multiple contact pins 123, and the socket 20 has multiple sockets 211. Each contact pin 123 can be inserted into the corresponding socket 211 to achieve electrical connection. The number of contact pins 123 and sockets 211 can be flexibly adjusted according to the working environment, for example, set to two, three, four, five, eight, ten, etc.
[0063] Furthermore, the length of the contact pin 123 can be compressed along the insertion direction. Therefore, when the contact pin 123 is inserted into the socket 211, it is compressed as it abuts against the bottom of the socket 211, while the top of the contact pin 123 always abuts against the bottom of the socket 211, thus ensuring a tight connection and preventing poor contact. When the contact pin 123 is not aligned with the socket 211, it abuts against the side of the socket 20 where the socket 211 is located and remains compressed due to the force. As the plug 10 rotates, the position of the contact pin 123 gradually changes with the plug 10. When the plug 10 rotates to the predetermined position and the contact pin 123 aligns with the socket 211, the contact pin 123 can automatically spring back and insert into the socket 211. Therefore, the user can blindly insert the plug 10 without observing the alignment of the contact pin 123 and the socket 211, thus improving work efficiency.
[0064] The ferrule 12 and the plug body 11 are detachably connected, so the ferrule 12 can be replaced. Depending on the work requirements, the ferrule 12 can be replaced with more or fewer contact pins 123, without having to replace the entire plug 10. This improves work efficiency and reduces material costs.
[0065] Specifically, the plug body 11 has a core-changing cavity 114, in which the plug core 12 can be accommodated to reduce the space occupied and increase the contact area and connection strength between the two.
[0066] The inner wall of the core replacement cavity 114 is provided with multiple snap-fit blocks 113 at intervals, and the outer periphery of the core 12 is provided with multiple snap-fit grooves 121. Each snap-fit block 113 can snap into the corresponding snap-fit groove 121, thereby further improving the compatibility and connection strength of the two.
[0067] Preferably, the shape of the snap-fit groove 121 is similar to the groove 16 described above, including a plug-in section 161 and a limiting section 162 connected to the plug-in section 161. The process of installing the plug 12 is as follows: first, the plug 12 is inserted into the replacement cavity 114. At this time, the snap-fit block 113 will first abut against the side of the plug 12 facing the replacement cavity 114. As the user rotates the plug 12 to a preset angle, the plug-in section 161 of the snap-fit groove 121 can be aligned with the snap-fit block 113, so that the snap-fit block 113 can enter. After the snap-fit block 113 enters the plug-in section 161, as the user continues to rotate the plug 12, the snap-fit block 113 can enter the limiting section 162. The limiting section 162 can limit the snap-fit block 113 to both sides along the axial direction of the plug 10, thereby preventing the plug 12 from coming out of the plug body 11.
[0068] Understandably, in other embodiments, the ferrule 12 and the plug body 11 can also be detachably connected in other ways. For example, the structural volume of the snap-fit block 113 can be slightly larger than that of the snap-fit groove 121, so that when the ferrule 12 is inserted into the ferrule replacement cavity 114, the snap-fit block 113 and the snap-fit groove 121 are interference-fitted and mutually restrained. Alternatively, a locking structure can be added to lock the ferrule 12 after it enters the ferrule replacement cavity 114 to prevent it from coming out.
[0069] Furthermore, the snap-fit block 113 is rectangular, and the insertion section 161 and the limiting section 162 in the snap-fit groove 121 are also rectangular, thus fitting the snap-fit block 113 and facilitating its entry. The edges of the snap-fit block 113 and the edges of the snap-fit groove 121 are rounded to guide the insertion and engagement of the two, reducing interference and collision.
[0070] Please see Figure 4 and Figure 7 The socket 20 has a protruding limiting ring 22, and one end of the plug 10 can extend into the limiting ring 22. Multiple protrusions 23 are spaced apart on the inner wall of the limiting ring 22. Multiple grooves 16 are formed on the outer periphery of the end of the plug 10 that inserts into the limiting ring 22, and each groove 16 corresponds to one of the protrusions 23. This facilitates the placement of the protrusions 23, allowing them to engage with the grooves 16 in the circumferential direction, increasing the limiting force points and improving connection strength.
[0071] Multiple protrusions 23 on the limiting ring 22 are evenly spaced, and the grooves 16 on the outer side of the plug 10 are also evenly opened corresponding to the positions of the protrusions 23, so as to improve the connection stability of the two.
[0072] The socket 20 includes a socket body 21, a pin socket 24, a circuit board 25, and terminals 26. One end of the pin socket 24 is connected to the socket body 21, and the other end is connected to the circuit board 25. The pin socket 24 is connected to the side of the circuit board 25 facing away from the socket body 21, and is electrically connected to the pin socket 24 through the circuit board 25. In this way, multiple pin sockets 24 can be connected to the socket body 21 and electrically connected to the terminals 26 simultaneously, without the need for separate electrical connections to the corresponding terminals 26. This reduces the usual wiring process, reduces cable space, and facilitates the adjustment of the number of pin sockets 24, as well as the replacement of different models and types of terminals 26.
[0073] The number of contact pin sockets 24 corresponds one-to-one with the number of contact pins 123. Each contact pin socket 24 is installed on the side of the socket 211 away from the plug 10. The contact pin 123 extends into the socket 211 and passes through the socket 211 to contact the contact pin socket 24. Each contact pin 123 is electrically connected to one contact pin socket 24.
[0074] The circuit board 25 has multiple female socket holes 251 for mounting the contact pin female socket 24. The number of female socket holes 251 corresponds to the number of contact pin female sockets 24. Each female socket hole 251 has a corresponding contact pin female socket 24 inserted through it, and the contact pin female socket 24 is fixed and limited to make it electrically connected to the circuit board 25.
[0075] Preferably, in this embodiment, both the pin socket 24 and the terminal 26 are connected to the circuit board 25 by soldering, which ensures both connection strength and electrical connection stability.
[0076] A mounting groove 212 is provided on the side of the socket body 21 away from the plug 10, and the circuit board 25 is embedded in the mounting groove 212. In this way, the space occupied by the circuit board 25 is reduced, and the connection between the circuit board 25 and the socket body 21 is increased.
[0077] Compared to existing technologies, this invention provides a protrusion 23 and a groove 16 on the plug 10 and socket 20. The groove 16 includes a insertion section 161, which allows the protrusion 23 to enter, thereby guiding the user to rotate the plug 10 to a preset angle so that the protrusion 23 enters the groove 16. The positioning member 13 can elastically abut against the plug 10 or socket 20. When the positioning member 13 abuts against the plug 10 or socket 20, it indicates that there is interference between it and the plug 10 or socket 20, that is, the plug 10 has not been rotated to the specified angle. In this case, the plug 10 cannot be inserted into the socket 20, avoiding the situation where the user misinserts or incorrectly inserts the plug 10 into the socket 20 due to objective factors such as lack of focus. When the positioning member 13 enters the positioning groove 221, it indicates that the plug 10 has been rotated to the preset angle. At this time, the limiting section 162 can restrict the movement of the protrusion 23 along the axial direction of the plug 10 or socket 20, thereby ensuring that the plug 10 will not come out of the socket 20.
[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0079] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
