Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and more particularly, to a locking mechanism for an electronic module. Background Art

[0002] After the electronic module is installed on the base, the electronic module and the base communicate through a connector. After the module is combined with the connector, in order to prevent signal instability caused by vibration, a mechanism for fixing the position of the module is usually required to ensure stable communication between the module and the base.

[0003] The existing fixing method for electronic modules is generally: fixing the entire electronic module on the base through several groups of screws. Therefore, when disassembling the entire electronic module, all the screws need to be removed one by one, and then the electronic module can be pulled out. The operation is time-consuming and laborious, and the installation process is also equally complicated and cumbersome. In addition, the screws are small in volume and are prone to be lost during the disassembly process. At the same time, the screws are prone to loosen under the influence of external vibration during long-term use, and the protection performance is poor.

[0004] Therefore, the current prior art realizes the locking and limiting functions through multiple screw parts, the disassembly and assembly are cumbersome and the protection performance is poor, and there is still room for improvement and development. Summary of the Utility Model

[0005] The purpose of this application is to provide a locking mechanism for an electronic module to solve the technical problems of cumbersome disassembly and assembly and poor protection performance in the installation of wall panels in the prior art.

[0009] A locking wrench, including a power-assisted wrench, a connecting shaft connected to the power-assisted wrench, and a locking structure. The power-assisted wrench is rotatably connected to the limiting portion through the connecting shaft, and the locking structure cooperates with the clamping portion to switch between a combined mode, a separation mode, and a debugging mode.

[0010] Further, the locking structure includes a first groove and a second groove provided on the power-assisted wrench, the clamping portion includes a limiting protrusion, and the electronic module is inserted into the receiving groove;

[0011] When the limiting protrusion is clamped and engaged in the first groove, the combined mode is formed;

[0012] When the limiting protrusion is engaged and snapped into the second groove, the debugging mode is formed;

[0013] When the limiting protrusion is separated from the first groove and the second groove, the separation mode is formed.

[0014] Furthermore, the first groove and the second groove are both provided with trapezoidal inclined surfaces on the side surfaces close to the connecting shaft.

[0015] In some embodiments, a pin is provided at the bottom of the electronic module, and a slot is provided at the bottom of the receiving tank;

[0016] In the combination mode, the pin is matingly inserted into the slot;

[0017] In the debugging mode and the separation mode, the pin is detached from the slot.

[0018] Furthermore, the base includes an upper shell, a connecting plate, and a lower shell, the upper shell is arranged to surround the accommodating groove and the limiting portion, the connecting plate is connected to the bottom of the upper shell, the slot is arranged on the connecting plate and extends to the bottom of the accommodating groove, and the lower shell is connected to the upper shell and covers the connecting plate between the upper shell and the lower shell.

[0019] In some embodiments, the inner side of the upper shell is provided with a convex edge arranged along the opening direction of the accommodating groove, and the convex edge is surrounded to form the limiting portion. When the electronic module is inserted into the accommodating groove, the convex edge surrounds and stops the side wall of the electronic module.

[0020] Further, the two ends of the power-assisted wrench along the length direction are respectively a first end and a second end, the connecting shaft is arranged at the first end and located on a side close to the slot, the second end is located on a side away from the slot and is provided with a buckle groove, and the limiting portion is provided with a clamping block;

[0021] In the combination mode and the debugging mode, the buckle slot is clamped on the clamping block;

[0022] In the separation mode, the buckle slot is separated from the clamping block.

[0023] In some embodiments, a wrench plate is further provided at the second end, the wrench plate is located at a side of the end surface of the second end facing away from the electronic module, and the snap-on groove is located at a side of the end surface of the second end close to the electronic module.

[0024] Furthermore, an auxiliary insertion hole extending into the interior of the power-assisting wrench is provided on the end surface of the second end, and the auxiliary insertion hole is located between the wrench plate and the buckle groove.

[0026] The locking mechanism for an electronic module provided by the present application has at least the following beneficial effects:

[0027] Compared with the traditional technology of using screws to connect and fix, there is no need to set up multiple screw holes, and the structure is simpler. The locking and unlocking process can be achieved by only turning the locking wrench. The operation is more convenient and labor-saving, and the electronic module can be plugged in and out in a smaller space. The locking wrench is set on the base, which can provide blocking protection for the electronic module inserted in the base, and the protection is stronger.

[0028] When the electronic module needs to be separated from the base, force is applied to the second end of the power-assisting wrench, and the first end of the power-assisting wrench begins to rotate around the connecting shaft. The side walls of the first groove and the second groove close to the connecting shaft can support the limiting protrusion of the electronic module and push it toward the separation position to complete the assisted extraction function.

[0029] When in the engagement mode or the adjustment mode, the first groove and the second groove are both facing the electronic module. External objects or water vapor will first contact the outer surface of the power-assisted wrench (the surface on the side facing away from the electronic module) and cannot directly contact the first groove and the second groove. The first groove and the second groove will not be affected by bumps and erosion by water vapor, thereby improving the stability of the card connection between the power-assisted wrench and the limit protrusion.

[0030] The electronic module can be completely placed in the receiving groove, and the receiving groove completely covers the electronic module to provide more comprehensive protection for the electronic module. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer and more understandable, the following further details this application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0054] It should be noted that when a component is referred to as "fixed to" or "disposed on" another component, it can be directly or indirectly located on that other component. When a component is referred to as "connected to" another component, it can be directly or indirectly connected to that other component. The orientations or positions indicated by the terms "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientations or positions shown in the accompanying drawings, and are only for the convenience of description and should not be construed as limiting the technical solution of this application. The terms "first" and "second" are only used for the purpose of convenient description and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of technical features. The meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0055] The following describes, in combination with the accompanying drawings, the locking mechanism for an electronic module according to an embodiment of this application.

[0056] Please refer to Figure 1 , Figure 1 which shows a schematic structural diagram of the locking mechanism for an electronic module 2 according to this application, including a base 1, an electronic module 2, and a locking wrench. The electronic module 2 is inserted into the base 1, and the locking wrench is used to adjust the locking degree between the electronic module 2 and the base 1 to switch different locking modes.

[0057] Specifically, referring to Figures 2 - 5 , the base 1 is provided with a receiving groove 12, and a limiting portion 13 is provided on the receiving groove 12. The electronic module 2 is detachably installed in the receiving groove 12 and abuts against the limiting portion 13. A clamping portion 21 is provided on the side wall of the electronic module 2. The locking wrench includes a boosting wrench 3, a connecting shaft 4 connected to the boosting wrench 3, and a locking structure 5. The boosting wrench 3 is rotatably connected to the limiting portion 13 through the connecting shaft 4, and the locking structure 5 cooperates with the clamping portion 21 to switch between a combined mode, a separated mode, and a debugging mode.

[0058] After the electronic module 2 is inserted into the receiving groove 12, in order to prevent signal instability caused by vibration, a clamping portion 21 and a locking wrench are respectively provided on the electronic module 2 and the base 1. Through the cooperation of the locking structure 5 and the clamping portion 21, the electronic module 2 is limited and fixed, thereby ensuring the stable installation between the electronic module 2 and the base 1, and also guaranteeing the stable communication.

[0059] When the electronic module 2 needs to be pulled out, the power wrench 3 is rotated to disengage the locking structure 5 of the locking wrench from the clamping portion 21, so that the limiting relationship between the electronic module 2 and the locking wrench can be released, and the electronic module 2 can be easily pulled out of the accommodating groove 12.

[0060] Compared with the traditional technology of using screws to connect and fix, there is no need to set up multiple screw holes, and the structure is simpler. The locking and unlocking process can be achieved by only turning the locking wrench, which is more convenient and labor-saving to operate, and the electronic module 2 can be plugged in and out in a smaller space; and the locking wrench is set on the base 1, which can provide blocking protection for the electronic module 2 inserted in the base 1, and the protection is stronger.

[0061] Furthermore, when in use, the relative position of the locking wrench and the clamping portion 21 can be adjusted to switch between the combination mode, separation mode and debugging mode. It can be understood that the combination mode is that the electronic module 2 is locked and fixed in the receiving groove 12 and the circuit connection can be completed, and the electronic module 2 can communicate with the base 1; the separation mode is that the electronic module 2 is detached from the lock of the receiving groove 12, and the electronic module 2 can be pulled out at any time; the debugging mode is applicable to the debugging stage. During the debugging process, the electronic module 2 needs to be fixed in one position. When switching to the debugging mode, the electronic module 2 will not be able to achieve communication connection with the base 1, nor will the electronic module 2 slide out of the receiving groove 12 of the base 1.

[0062] By turning the locking wrench and adjusting the cooperation between the locking structure 5 and the clamping portion 21, the locking mechanism can be switched between the engagement mode, the separation mode and the adjustment mode. It uses fewer structural components, has a simple structure and low cost, and is easy and quick to operate. It abandons the traditional method of fixing the electronic module 2 with screws to limit the position, thereby improving the efficiency of the user.

[0063] In some embodiments, see Figures 3 - 9 The locking structure 5 includes a first groove 51 and a second groove 52 provided on the power wrench 3, the clamping portion 21 includes a limiting protrusion 22, and the electronic module 2 is inserted into the accommodating groove 12. When the limiting protrusion 22 is engaged and engaged in the first groove 51, a combination mode is formed. When the limiting protrusion 22 is engaged and engaged in the second groove 52, a debugging mode is formed. When the limiting protrusion 22 is separated from the first groove 51 and the second groove 52, a separation mode is formed.

[0064] When in use, the power-assisting wrench 3 is pulled to make the power-assisting wrench 3 rotate around the side wall of the base 1 with the connecting shaft 4 as the axis, so that the power-assisting wrench 3 is away from the electronic module 2. At this time, the first groove 51 and the second groove 52 on the power-assisting wrench 3 are also away from the electronic module 2. There is no lock between the electronic module 2 and the base 1, and the electronic module 2 can be inserted and pulled out of the accommodating groove 12 at any time, that is, it is in the separation mode.

[0065] When it is necessary to adjust from the separation mode to the combination mode, turn the power-assisted wrench 3 in the reverse direction, so that the power-assisted wrench 3 approaches the electronic module 2 and the first groove 51 is engaged with the limit projection 22 on the electronic module 2. At this time, the electronic module 2 is locked between the bases 1, and the electronic module 2 can complete the circuit connection, and communication can be achieved between the electronic module 2 and the base 1, that is, it is in the combination mode.

[0066] When it is necessary to adjust from the separation mode to the debugging mode, also turn the power-assisted wrench 3 in the reverse direction, so that the power-assisted wrench 3 approaches the electronic module 2. Different from the combination mode, the second groove 52 is engaged with the limit projection 22 on the electronic module 2. At this time, the electronic module 2 is locked between the bases 1, and the electronic module 2 has not completed the circuit connection, and communication cannot be achieved between the electronic module 2 and the base 1, that is, it is in the debugging mode.

[0067] When it is necessary to adjust from the combination mode to the debugging mode, first pull the power-assisted wrench 3 to adjust to the separation mode, and then adjust the position of the electronic module 2 in the accommodation groove 12 so that the position of the limit projection 22 corresponds to the second groove 52, and then pull the power-assisted wrench 3 in the reverse direction so that the second groove 52 is engaged with the limit projection 22.

[0068] It can be seen that when switching between different state modes, only the power-assisted wrench 3 needs to be pulled and the position of the electronic module 2 is finely adjusted accordingly. The structure is simple and the operation is convenient.

[0069] Furthermore, referring to Figures 3 - 5 , the first groove 51 and the second groove 52 are arranged along the length direction of the power-assisted wrench 3. Or rather, the first groove 51 and the second groove 52 are arranged along the direction of the first end and the second end. The two ends of the power-assisted wrench 3 along the length direction are the first end and the second end respectively. The first end is the end close to the connecting shaft 4, and the second end is the end far from the connecting shaft 4. And the first groove 51 is located on the side close to the first end, and the second groove 52 is located on the side close to the second end.

[0070] It can be understood that when adjusted to the combination mode, the electronic module 2 is electrically connected to the bottom of the accommodation groove 12. When adjusted to the debugging mode, the electronic module 2 is disconnected from the bottom of the accommodation groove 12. The first groove 51 is arranged on one side of the first end. When the limit projection 22 on the electronic module 2 is engaged with the first groove 51, the electronic module 2 is closer to the bottom of the accommodation groove 12. When the limit projection 22 on the electronic module 2 is engaged with the second groove 52, the electronic module 2 is relatively far from the bottom of the accommodation groove 12.

[0071] Furthermore, in the related art, due to the need to use screws for fixing or due to other structural limitations, the electronic module 2 must be at least partially exposed when mating with the base 1 to complete the fixation, but this also increases the risk of the electronic module 2 being corroded by the external environment.

[0072] In this embodiment, no matter in the combination mode or the debugging mode, the electronic module 2 is arranged in the receiving groove 12 of the base 1, and the power-assisting wrench 3 is arranged on the limiting portion 13, that is, the power-assisting wrench 3 is always located outside the electronic module 2, which is equivalent to the power-assisting wrench 3 can prevent objects outside the receiving groove 12 from corroding the electronic module 2. At the same time, the electronic module 2 can also be completely placed in the receiving groove 12, and the receiving groove 12 completely covers the electronic module 2 to provide more comprehensive protection for the electronic module 2. In other words, when making the base 1, the shape of the base 1 can be selected according to the actual situation to achieve the effect of completely covering the electronic module 2, or partially covering the electronic module 2.

[0073] It can be understood that the first groove 51 and the second groove 52 are key structures for clamping and limiting with the limiting protrusion 22. If the first groove 51 or the second groove 52 faces outward, external objects can easily bump into or erode the first groove 51 or the second groove 52, causing damage to the first groove 51 and the second groove 52, resulting in the first groove 51 and the second groove 52 being unable to clamp the limiting protrusion 22, that is, unable to stably remain in the coupling module or the debugging module.

[0074] In this embodiment, when the power wrench 3 is tightened, refer to Figure 3 and Figure 5 That is, when in the combination mode or the adjustment mode, the first groove 51 and the second groove 52 are both facing the electronic module 2, and external objects or water vapor will first contact the outer surface of the power-assisting wrench 3 (the side surface facing away from the electronic module 2), and cannot directly contact the first groove 51 and the second groove 52. The first groove 51 and the second groove 52 will not be affected by bumps and erosion by water vapor, thereby improving the stability of the clamping between the power-assisting wrench 3 and the limiting protrusion 22.

[0075] Furthermore, when the electronic module 2 needs to be separated from the base 1, force is applied to the second end of the power wrench 3, and the first end of the power wrench 3 begins to rotate around the connecting shaft 4. The side walls of the first groove 51 and the second groove 52 close to the connecting shaft 4 can both support the limiting protrusion 22 of the electronic module 2 and push it out to the separation position, completing the auxiliary extraction function. Since the distance between the force-applying end (the second end) and the connecting shaft 4 is greater than the distance between the force-receiving end (the first end) and the connecting shaft 4, the power wrench 3 has a lever effect when rotating, and can separate the electronic module 2 from the base 1 with a small force, playing the role of assisting extraction.

[0076] Further, during the extraction process, whether in the combined mode or the separation mode, the sides of the first groove 51 and the second groove 52 close to the connecting shaft 4 abut against the limiting protrusion 22 on the electronic module 2. Refer to Figure 8 and Figure 9 , by setting the sides of the first groove 51 and the second groove 52 close to the connecting shaft 4 as trapezoidal inclined surfaces 53, it can make the trapezoidal inclined surfaces 53 have a certain guiding effect when abutting against the first groove 51 and the second groove 52, and can push the limiting protrusion 22 out to the separation position more smoothly, reducing the situation where the limiting protrusion 22 is stuck in the first groove 51 or the second groove 52.

[0077] Exemplarily, if the sides of the first groove 51 and the second groove 52 close to the connecting shaft 4 are both set as vertical surfaces, then when the vertical surfaces push out the limiting protrusion 22, if the gap between the limiting protrusion 22 and the first groove 51 and the second groove 52 is very small, the limiting protrusion 22 is likely to be stuck in the first groove 51 or the second groove 52, resulting in the inability to smoothly push out the limiting protrusion 22. After setting the sides of the first groove 51 and the second groove 52 close to the connecting shaft 4 as trapezoidal inclined surfaces 53, even if the limiting protrusion 22 fits tightly with other sides of the first groove 51 and the second groove 52, it can still slide out smoothly through the trapezoidal inclined surfaces 53.

[0078] In some embodiments, refer to Figure 6 , the bottom of the electronic module 2 is provided with pins 23, and the bottom of the receiving groove 12 is provided with slots 15. In the combined mode, the pins 23 are inserted and connected in the slots 15, and the electronic module 2 realizes electrical connection and communication with the bottom of the receiving groove 12. In the debugging mode and the separation mode, the pins 23 are separated from the slots 15, and the electronic module 2 disconnects the electrical connection with the bottom of the receiving groove 12.

[0079] It can be understood that the pins 23 refer to electronic connectors connected to the bottom of the electronic module 2, and the slots 15 refer to the base 1 connectors provided at the bottom of the receiving groove 12. After the pins 23 are inserted into the slots 15, it is equivalent to the completion of the electrical connection between the electronic connector and the base 1 connector, that is, communication is realized between the electronic module 2 and the base 1.

[0080] In some embodiments, refer to Figures 2 - 5 , the base 1 includes an upper housing 11, a connecting plate 16, and a lower housing 17. The upper housing 11 encloses to form the receiving groove 12 and the limiting portion 13. The connecting plate 16 is connected to the bottom of the upper housing 11. The slots 15 are provided on the connecting plate 16 and extend to the bottom of the receiving groove 12. The lower housing 17 is connected to the upper housing 11 and wraps the connecting plate 16 between the upper housing 11 and the lower housing 17.

[0081] When assembling the base 1, insert the slot 15 of the connecting plate 16 into the accommodating groove 12 from the bottom of the upper housing 11, then fixedly connect the connecting plate 16 to the bottom of the upper housing 11. Next, wrap the lower housing 17 around the connecting plate 16 and connect the lower housing 17 to the bottom of the upper housing 11. In this way, the connecting plate 16 can be protected by the upper housing 11 and the lower housing 17 to avoid interference and collision from external objects.

[0082] Furthermore, the connecting plate 16 includes a PCB board (Printed Circuit Board).

[0083] In some embodiments, refer to Figure 2 and Figure 10 , a convex edge is provided on the inner side of the upper housing 11 along the opening direction of the accommodating groove 12. The convex edges surround and form a limiting portion 13. When the electronic module 2 is inserted into the accommodating groove 12, the convex edges surround and abut against the side wall of the electronic module 2.

[0084] Specifically, the convex edges are distributed and connected to the accommodating groove 12, cooperating with the outer wall of the electronic module 2, serving as a guiding mechanism when the electronic module 2 is inserted into the base 1. When the assisting wrench 3 pries up the electronic module 2, it also has a limiting function to ensure that the electronic module 2 moves straight to disengage from the base 1.

[0085] Furthermore, refer to Figures 2 - 5 and Figure 8 and Figure 9 , the two ends of the assisting wrench 3 along the length direction are respectively a first end and a second end. The connecting shaft 4 is arranged at the first end and is located on the side close to the slot 15. The second end is located on the side far from the slot 15 and is provided with a buckling groove 31. A clamping block 14 is provided on the limiting portion 13. In the combination mode and the debugging mode, the buckling groove 31 is clamped to the clamping block 14. In the separation mode, the buckling groove 31 disengages from the clamping block 14.

[0086] When the electronic module 2 needs to be fixed to the base 1, apply a force in the direction of the electronic module 2 at the second end of the assisting wrench 3. The first end of the assisting wrench 3 starts to rotate around the connecting shaft 4, and the buckling groove 31 of the assisting wrench 3 is clamped to the clamping block 14 on the limiting portion 13, realizing the locking of the assisting wrench 3 and the base 1.

[0087] When the electronic module 2 needs to be separated from the base 1, apply a force in the direction away from the electronic module 2 at the second end of the assisting wrench 3. The first end of the assisting wrench 3 starts to rotate around the connecting shaft 4, and the buckling groove 31 of the assisting wrench 3 disengages from the clamping block 14, releasing the locking relationship between the assisting wrench 3 and the base 1.

[0088] Furthermore, refer to Figures 2 - 5 and Figure 8 and Figure 9The second end is also provided with a wrench plate 32, which is located on the side of the end surface of the second end away from the electronic module 2, and the buckle groove 31 is located on the side of the end surface of the second end close to the electronic module 2.

[0089] The wrench plate 32 is equivalent to adding a structure that is convenient for finger pulling, and increases the force arm, making it more convenient to apply force, making the process of pulling the power wrench 3 more labor-saving and convenient.

[0090] In some embodiments, see Figures 2 - 5 as well as Figure 8 and Figure 9 An auxiliary insertion hole 33 extending to the inside of the power-assisting wrench 3 is provided on the end surface of the second end, and the auxiliary insertion hole 33 is located between the wrench plate 32 and the buckle groove 31.

[0091] The auxiliary insertion hole 33 provided on the power-assisting wrench 3 can be used to insert a tool such as a screwdriver into the hole to assist in moving the power-assisting wrench 3 when the operating space is small.

[0092] Further, see Figure 2 and Figure 10 A torsion spring 41 is sleeved on the connecting shaft 4, and a first limiting groove 34 and a second limiting groove 35 are provided in the power-assisting wrench 3. The two ends of the torsion spring 41 are respectively clamped in the first limiting groove 34 and the second limiting groove 35. The second limiting groove 35 is connected to the side of the limiting portion 13 away from the electronic module 2.

[0093] The torsion spring 41 is sleeved on the connecting shaft 4 of the power-assisting wrench 3 . When the power-assisting wrench 3 is opened, the power-assisting wrench 3 is kept in an open state under the action of the torsion spring 41 , so that the power-assisting wrench 3 can be opened to a fixed angle under the action of the torsion spring 41 .

[0094] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
