[0001] The present application relates to the field of optical communication technology, in particular to an unlocking mechanism, an optical module, an optical communication device and a vehicle. BACKGROUND

[0002] In the related art, the optical module with the unlocking mechanism is usually pluggable arranged in a cage. By pulling the pull ring of the unlocking mechanism, the unlocking part of the unlocking arm of the pull ring drives the elastic tab of the cage to act, so as to realize the unlocking between the optical module and the cage, so as to facilitate the pulling of the optical module from the cage. Wherein, the pull ring and the base are usually reset by the elastic member. The base is provided with a spring groove to accommodate the spring, and the pull ring is provided with a mounting hole. The spring is inserted from the mounting hole and installed in the spring groove. In order to prevent the spring from jumping out of the mounting hole during the pulling of the pull ring, the hole diameter of the mounting hole is small, which causes the spring to be extremely inconvenient to install and disassemble.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0046] According to the first aspect of this application, referring to Figures 1 to 10 This application provides an unlocking mechanism. The unlocking mechanism includes a base 1, a pull ring 2, and an elastic member 3. The base 1 has a first mounting groove 11. A mounting opening 12 is formed on the groove wall of the first mounting groove 11. The pull ring 2 is slidably connected to the base 1. The mounting opening 12 protrudes from the pull ring 2. The pull ring 2 has an abutment portion 21 extending toward the first mounting groove 11. The elastic member 3 is configured to be installed into the first mounting groove 11 from the mounting opening 12. One end of the elastic member 3 abuts against the groove wall of the first mounting groove 11, and the other end abuts against the abutment portion 21.

[0047] In this embodiment, the elastic member 3 is accommodated by constructing a first mounting groove 11 on the base 1. The groove wall of the first mounting groove 11 has a mounting opening 12. Since the mounting opening 12 protrudes from the pull ring 2, after the pull ring 2 is installed on the base 1, the elastic member 3 can be installed into the first mounting groove 11 through the mounting opening 12. Therefore, it is unnecessary to construct mounting holes on the pull ring 2 to install the elastic member 3. Furthermore, in the above installation method, both ends of the elastic member 3 abut against the abutment portion 21 and the groove wall of the first mounting groove 11, respectively. The two ends of the elastic member 3 are stably limited, and the installation of the elastic member 3 is very stable, preventing it from falling out of the first mounting groove 11. It is evident that by using a mounting opening 12 formed on the groove wall of the first mounting groove 11 of the base 1 instead of a mounting hole on the pull ring 2, the elastic member 3 can be installed into the first mounting groove 11 from the space on the side of the first mounting groove 11, making the installation and removal of the elastic member 3 simpler and more convenient.

[0048] Understandably, the pull ring 2 covers a portion of the first mounting groove 11, so that the pull ring 2 at least partially closes the opening of the first mounting groove 11 and exposes the mounting opening 12. The abutment portion 21 constructed on the pull ring 2 is L-shaped and includes a connecting section and an abutment section. The connecting section and the abutment section are integrally formed. The connecting section extends along the extension direction of the first mounting groove 11 toward the mounting opening 12, so that the pull ring 2 itself partially covers the mounting opening 12. When the pull ring 2 is installed on the base 1, the mounting opening 12 is not closed by the pull ring 2. Thus, the elastic member 3 can be installed into the first mounting groove 11 from the mounting opening 12.

[0049] In some embodiments, the extending direction of the first mounting groove 11 is the same as the direction in which the pull ring 2 and the base 1 slide relative to each other. That is, when the pull ring 2 and the base 1 slide relative to each other along the first direction, the first mounting groove 11 extends along the first direction.

[0050] In some embodiments, the first mounting groove 11 is disposed on the base 1 near the side in the width direction. Alternatively, the first mounting groove 11 may also be disposed on the base 1 near the center in the width direction.

[0051] In some embodiments, the first mounting groove 11 is configured as a square groove. One end of the elastic member 3 abuts against the groove wall surface of the first mounting groove 11 adjacent to or relative to the mounting opening 12, and the other end abuts against the abutment portion 21.

[0052] like Figure 9 and Figure 10 As shown, in some embodiments, the mounting opening 12 can be disposed on the groove wall surface of the first mounting groove 11 in the first direction. In this case, the first mounting groove 11 is located near the center of the base 1. The pull ring 2 completely closes the opening of the first mounting groove 11. The abutment portion 21 can be disposed outside the first mounting groove 11, and the abutment portion 21 is directly opposite the mounting opening 12. After the elastic member 3 is installed in the first mounting groove 11 through the mounting opening 12, one end of the elastic member 3 abuts against the groove wall surface of the first mounting groove 11 relative to the mounting opening 12, and the other end of the elastic member 3 protrudes from the first mounting groove 11 through the mounting opening 12 and abuts against the abutment portion 21.

[0053] like Figure 2 and Figure 3 As shown, in some embodiments, the mounting opening 12 can be disposed on the groove wall surface of the first mounting groove 11 located in the second direction. The first direction and the second direction are angled. For example, the first direction is perpendicular to the second direction. In this case, the first mounting groove 11 is located near the edge of the base 1. The pull ring 2 partially closes the opening of the first mounting groove 11. The abutment portion 21 can be disposed within the first mounting groove 11 and corresponds to the groove segment where the mounting opening 12 is disposed. After the elastic member 3 is installed in the first mounting groove 11 from the mounting opening 12, one end of the elastic member 3 abuts against the groove wall surface of the first mounting groove 11 adjacent to the mounting opening 12, and the other end of the elastic member 3 abuts against the abutment portion 21.

[0054] In some embodiments, the elastic element 3 is a spring.

[0055] In some embodiments, the mounting opening 12 is located on the side surface of the base 1. This prevents the pull ring 2 from closing the mounting opening 12 after it is installed on the base 1, leaving the mounting opening 12 exposed so that the elastic member 3 can be installed from the mounting opening 12 into the first mounting groove 11.

[0056] Please continue reading. Figure 2 andFigure 3 In some embodiments, the first mounting groove 11 includes a first groove segment 111 and a second groove segment 112. A mounting opening 12 is formed on the groove wall of the first groove segment 111. A pull ring 2 closes the opening of the second groove segment 112. An abutment portion 21 is provided within the first groove segment 111. One end of the elastic member 3 abuts against the groove wall of the second groove segment 112, and the other end abuts against the abutment portion 21.

[0057] Understandably, when the pull ring 2 partially closes the first mounting groove 11, the pull ring 2 only closes the opening of the second groove segment 112, while the opening of the first groove segment 111 remains open. The abutment portion 21 extends along the direction from the second groove segment 112 to the first groove segment 111 and is disposed within the first groove segment 111. The mounting opening 12 is located on the groove wall of the first groove segment 111. Based on the above arrangement, it can be ensured that the mounting opening 12 is not closed by the pull ring 2 and the abutment portion 21, thereby allowing the elastic member 3 to be installed into the first mounting groove 11 from the mounting opening 12.

[0058] In some embodiments, the first mounting groove 11 extends along a first direction, and the first groove segment 111 and the second groove segment 112 are distributed along the first direction. The mounting opening 12 is disposed on the groove wall surface of the first groove segment 111 located in the first direction; or, the mounting opening 12 is disposed on the groove wall surface of the first groove segment 111 located in the second direction.

[0059] In some embodiments, the mounting opening 12 is disposed on the groove wall surface of the first groove segment 111 in the second direction, and the mounting opening 12 completely covers the second groove segment 112. This results in a larger opening size for the mounting opening 12, facilitating the installation of the elastic member 3.

[0060] In some embodiments, the length of the first slot segment 111 is greater than the length of the second slot segment 112. Alternatively, the length of the first slot segment 111 is equal to the length of the second slot segment 112.

[0061] Please see Figure 7 and Figure 8 In some embodiments, the base 1 is further provided with a second mounting groove 13. The second mounting groove 13 is connected to the first mounting groove 11 through a mounting port 12. The pull ring 2 is offset from the second mounting groove 13.

[0062] It is understandable that, based on the second mounting groove 13 provided on the base 1, the second mounting groove 13 is connected to the first mounting groove 11 through the mounting port 12. When the opening of the first mounting groove 11 is closed by the pull ring 2 or the abutment part 21, the elastic member 3 can pass through the opening of the second mounting groove 13 into the second mounting groove 13, and pass through the mounting port 12 into the first mounting groove 11, so as to realize the installation of the elastic member 3 in the first mounting groove 11.

[0063] It should be noted that the misalignment between the pull ring 2 and the second mounting groove 13 means that neither the pull ring 2 nor the abutment part 21 closes the opening of the second mounting groove 13. Alternatively, along the height direction of the unlocking mechanism, the projections of the pull ring 2 and the abutment part 21 are misaligned with the projections of the second mounting groove 13.

[0064] In this embodiment, the second mounting groove 13 extends the distance between the first mounting groove 11 and the side surface of the base 1. This allows for better installation and removal of the elastic element 3, and reduces the likelihood of the elastic element 3 detaching from the first mounting groove 11, thus improving the reliability of the elastic element 3 installation. Simultaneously, the second mounting groove 13 provides a locking space for the locking portion 41 of the top cover 4, facilitating the assembly of the top cover 4.

[0065] Please continue reading. Figure 7 and Figure 8 In some embodiments, the second mounting groove 13 has a first opening 14. The first opening 14 extends through the base 1 on the side away from the first mounting groove 11.

[0066] Understandably, the second mounting groove 13 forms a first opening 14 on the side surface of the base 1. Since the pull ring 2 is mounted on the base 1 from the upper side, the pull ring 2 will not close the first opening 14. After the pull ring 2 is connected to the base 1, the elastic element 3 can be inserted into the second mounting groove 13 through the first opening 14 and into the first mounting groove 11 through the mounting port 12, thereby assembling the elastic element 3.

[0067] Even if the pull ring 2 or the abutment part 21 partially or completely covers the opening of the second mounting groove 13 due to manufacturing errors of the pull ring 2 and the abutment part 21, the elastic member 3 can still be inserted into the second mounting groove 13 through the first opening 14 and into the first mounting groove 11 through the mounting port 12 to achieve the assembly of the elastic member 3.

[0068] Please continue reading. Figure 8 In some embodiments, both the first mounting groove 11 and the second mounting groove 13 extend along a first direction, and the first mounting groove 11 and the second mounting groove 13 are distributed along a second direction. A portion of the first mounting groove 11 and a portion of the second mounting groove 13 are connected through a mounting port 12.

[0069] The first direction and the second direction are set at an angle.

[0070] It is understood that the first mounting groove 11 and the second mounting groove 13 are arranged side by side along the second direction, and a portion of their groove sections are connected by the mounting port 12, so that the first mounting groove 11 and the second mounting groove 13 form a roughly Z-shaped groove structure after being connected. This facilitates the installation of the elastic member 3 into the first mounting groove 11 from the first opening 14 and the mounting port 12, and ensures that the groove wall surface of the first mounting groove 11 on the side with the mounting port 12 has sufficient length to restrain the elastic member 3 and prevent the elastic member 3 from popping out from the mounting port 12.

[0071] In some embodiments, the first direction and the second direction are set at an acute angle. Alternatively, the first direction and the second direction are set at an obtuse angle. Alternatively, the first direction and the second direction are perpendicular to each other.

[0072] For example, the first direction is the length direction of the base 1, and the second direction is the width direction of the base 1.

[0073] In some embodiments, the bottom surface of the first mounting groove 11 is flush with the bottom surface of the second mounting groove 13 to facilitate the installation of the elastic member 3. The horizontal plane where the opening of the first mounting groove 11 is located may be higher than the plane where the opening of the second mounting groove 13 is located. Thus, an optical fiber connector can be installed near the opening of the second mounting groove 13.

[0074] In some embodiments, the side surface of the base 1 is provided with a groove 15. The pull ring 2 includes a main body 24 and an unlocking arm 22 connected to the main body 24. The unlocking arm 22 is disposed in the groove 15. The end of the unlocking arm 22 away from the pull ring 2 is provided with an unlocking part 221. The unlocking part 221 is configured to move with the pull ring 2 and drive the elastic lever of the cage to move.

[0075] Understandably, the optical module has a locked state and an unlocked state. In the locked state, the optical module is reliably fixed inside the cage. In the unlocked state, the optical module can also be pulled out from the cage. When the optical module is in the locked state, the unlocking part 221 of the unlocking arm 22 and the elastic tab of the cage are either far apart or only close together without interaction force. The elastic tab abuts against the side surface of the pull ring 2, base 1, or top cover 4 of the optical module to achieve position locking of the optical module. When the optical module is in the unlocked state, the unlocking part 221 of the unlocking arm 22 abuts against the elastic tab inside the cage, and with the movement of the pull ring 2, the unlocking part 221 pushes up the elastic tab, thereby moving the elastic tab away from the side surface of the pull ring 2, base 1, or top cover 4, to achieve unlocking of the optical module.

[0076] It should be noted that the unlocking arm 22 is a flexible arm. At the end near the unlocking part 221, the unlocking arm 22 has a bent section that bends towards the side surface of the base 1, and the unlocking part 221 is located at the end of the bent section. The shape of the bottom surface of the groove 15 matches the shape of the unlocking arm 22. When the pull ring 2 moves away from the base 1, the unlocking arm 22, the bent section, and the unlocking part 221 all move accordingly. After the bent section moves, it deforms based on the fit between its own shape and the bottom surface of the groove 15, causing the bent section and the unlocking part 221 to move away from the side surface of the base 1. Thus, the unlocking part 221 moves towards the inner surface of the cage, driving the flexible lever gradually away from the base 1, thereby unlocking the optical module.

[0077] The height of the groove 15 can be matched with the height of the unlocking arm 22 to ensure that the unlocking arm 22 can be installed in the groove 15. The groove 15 is used to limit the upper and lower sides of the unlocking arm 22 to prevent relative movement in the height direction between the unlocking arm 22 and the groove 15, so that the pull ring 2 and the base 1 can only slide relative to each other in the first direction.

[0078] like Figure 1 and Figure 7 As shown, in some embodiments, the unlocking mechanism further includes a top cover 4. The top cover 4 is connected to the base 1. A second opening 16 is formed on the side of the groove 15 facing the top cover 4. The top cover 4 closes the first mounting groove 11 and the second opening 16.

[0079] Understandably, the top cover 4 fits over the upper side of the base 1, and the connecting part 23 of the pull ring 2 is clamped between the top cover 4 and the base 1. The groove 15 forms a second opening 16 on the side facing the top cover 4. Therefore, when assembling the unlocking arm 22, the assembly of the upper side of the unlocking arm 22 can be disregarded initially; the lower side of the unlocking arm 22 can simply abut against the bottom surface of the groove 15, facilitating quick assembly of the unlocking arm 22. After the top cover 4 is connected to the base 1, it can close the second opening 16, thereby limiting the upper side of the unlocking arm 22 and ensuring reliable installation of the unlocking arm 22.

[0080] The top cover 4 can also close the first mounting groove 11. Thus, the top cover 4 and the pull ring 2 completely close the opening of the first mounting groove 11, so that the upper and lower sides of the elastic element 3 are limited by the solid components, ensuring the reliability of the elastic element 3 during the pulling process.

[0081] like Figure 1 and Figure 5 As shown, in some embodiments, the base 1 is further provided with a second mounting groove 13. The second mounting groove 13 communicates with the first mounting groove 11 through a mounting opening 12. The top cover 4 is provided with a snap-fit ​​portion 41 protruding toward the base 1. The snap-fit ​​portion 41 is disposed in the second mounting groove 13 and closes the mounting opening 12.

[0082] Understandably, after the snap-fit ​​part 41 is engaged with the second mounting groove 13, it can close the mounting opening 12. Thus, the opening of the first mounting groove 11 is completely closed by the top cover 4 and the pull ring 2, and the mounting opening 12 of the first mounting groove 11 is closed by the snap-fit ​​part 41, thereby placing the first mounting groove 11 in a completely closed state. At this time, the elastic element 3 is physically limited in all directions, ensuring the reliability of the elastic element 3 during the pulling process of the pull ring 2.

[0083] In some embodiments, the snap-fit ​​portion 41 is integrally formed on the top cover 4. The length of the snap-fit ​​portion 41 is the same as the length of the second mounting groove 13, so that the snap-fit ​​portion 41 can completely cover the length direction of the second mounting groove 13, ensuring that the snap-fit ​​portion 41 can close the mounting opening 12.

[0084] Please see Figure 5 and Figure 6 In some embodiments, the bottom surface of the groove 15 is provided with a first limiting portion 17 protruding toward the top cover 4. The first limiting portion 17 abuts against the unlocking arm 22. And / or, the top cover 4 is provided with a second limiting portion 42 protruding toward the base 1. The second limiting portion 42 abuts against the unlocking arm 22.

[0085] Understandably, the first limiting part 17 can limit the lower side of the unlocking arm 22 and create a certain distance between the unlocking arm 22 and the bottom surface of the groove 15. This greatly increases the machining tolerance of the unlocking arm 22 of the pull ring 2, preventing defects such as local burrs or dimensional errors during machining that could cause the pull ring 2 to jam. The second limiting part 42 can limit the upper side of the unlocking arm 22 and create a certain distance between the unlocking arm 22 and the lower surface of the top cover 4. This also greatly increases the machining tolerance of the unlocking arm 22 of the pull ring 2, preventing defects such as local burrs or dimensional errors during machining that could cause the pull ring 2 to jam.

[0086] For example, a first limiting portion 17 protruding towards the top cover 4 is constructed only on the bottom surface of the groove 15. Alternatively, a second limiting portion 42 protruding towards the base 1 is constructed only on the top cover 4. Alternatively, a first limiting portion 17 protruding towards the top cover 4 is constructed on the bottom surface of the groove 15, and a second limiting portion 42 protruding towards the base 1 is constructed on the top cover 4.

[0087] Please continue reading. Figure 1 and Figure 5 In some embodiments, the unlocking arms 22 are spaced two apart. The two unlocking arms 22 are located on opposite sides of the base 1. A connecting portion 23 connects the two unlocking arms 22. The abutting portion 21 is connected to the connecting portion 23. A clearance notch 43 is formed on the side of the top cover 4 facing the base 1. The connecting portion 23 is connected to the clearance notch 43.

[0088] It is understandable that the two unlocking arms 22 are respectively connected to the opposite sides of the base 1, and the side surfaces of the opposite sides of the base 1 are provided with grooves 15. The arrangement of the two unlocking arms 22 makes the sliding connection between the pull ring 2 and the base 1 more stable, and the unlocking part 221 of the two unlocking arms 22 can push open the two elastic levers to ensure that unlocking is possible.

[0089] It should be noted that the two unlocking arms 22 have the same shape, and the distance between the two unlocking arms 22 is the width of the base 1.

[0090] like Figure 1 As shown, the connecting part 23 is used to connect the two unlocking arms 22, and the abutment part 21 is disposed on the connecting part 23, so that the installation position of the abutment part 21 on the connecting part 23 can be selected based on the position of the first mounting groove 11, so as to ensure that the abutment part 21 can correspond to the first mounting groove 11.

[0091] It is understood that the connecting part 23 spans the width direction of the base 1, the top cover 4 covers the bottom plate, and the clearance notch 43 on the top cover 4 is used to accommodate the connecting part 23 so that the connecting part 23 can be disposed between the top cover 4 and the bottom plate.

[0092] Please continue reading. Figure 1 and Figure 5 In some embodiments, the length of the clearance notch 43 is greater than the length of the connecting portion 23 along the first direction. The length difference between the clearance notch 43 and the connecting portion 23 defines the maximum stroke of the pull ring 2.

[0093] Understandably, the pull ring 2 and the base 1 will move relative to each other in the first direction. Since the top cover 4 and the base 1 are relatively fixed, when the pull ring 2 is pulled, the connecting part 23 and the top cover 4 will move relative to each other in the first direction. At this time, the connecting part 23 will slide within the clearance notch 43. The length of the clearance notch 43 is greater than the length of the connecting part 23 to ensure that the connecting part 23 can be pulled a certain distance.

[0094] It should be noted that the length difference between the clearance notch 43 and the connecting part 23 limits the maximum stroke of the pull ring 2, so that the pull ring 2 can only operate within the second maximum stroke range.

[0095] Please continue reading. Figure 3 In some embodiments, the unlocking arm 22 is configured with a guide notch 222 extending along a first direction. The groove wall of the groove 15 is configured with a guide portion 18. The guide portion 18 is slidably disposed within the guide notch 222. The side of the guide portion 18 facing the bottom surface of the groove 15 is configured as arc-shaped.

[0096] Understandably, the sliding engagement between the guide portion 18 and the guide notch 222 restricts and guides the sliding direction of the unlocking arm 22, thereby limiting the sliding direction of the pull ring 2. The side of the guide portion 18 facing the bottom surface of the groove 15 contacts the lower surface of the guide notch 222. Since the side of the guide portion 18 facing the bottom surface of the groove 15 is set to be arc-shaped, the contact area between the guide portion 18 and the guide notch 222 can be reduced, which is more conducive to the relative sliding of the two.

[0097] For example, the side of the guide portion 18 facing the bottom surface of the groove 15 is set to be semi-circular or semi-elliptical.

[0098] It should be noted that the pull ring 2 is installed on the base 1 in a top-to-bottom direction. To facilitate the assembly between the guide portion 18 and the guide notch 222, a slope is provided on the side of the guide portion 18 away from the bottom surface of the groove 15. In a bottom-to-top direction, the slope is inclined away from the unlocking arm 22.

[0099] Please continue reading. Figure 1 and Figure 4 In some embodiments, a recessed area 151 is formed on the bottom surface of the groove 15 at the end away from the unlocking part 221. The end of the unlocking arm 22 away from the unlocking part 221 is at least partially engaged in the recessed area 151.

[0100] Understandably, since the end of the unlocking arm 22 away from the unlocking part 221 is at least partially engaged within the recessed area 151, the recessed area 151 can be used to engage and limit the unlocking arm 22. When assembling the pull ring 2, defects caused by deformation of the pull ring 2 can be prevented.
