[0001] This application belongs to the field of locking structures, and particularly relates to a locking structure. Background Art

[0002] In various devices and systems, in order to prevent misoperation or ensure safety in specific situations, it is often necessary to lock certain buttons. The following are some common application scenarios where button locking is required: For example, in microwave ovens, ovens, etc., during use, the settings may be changed due to accidental touch. Therefore, these devices usually have a locking function to prevent children or inadvertent operations from causing the device to turn on or the settings to be changed. In-vehicle entertainment systems, navigation systems, and start buttons, etc., may need to be locked in certain situations. For example, when the vehicle is moving, to prevent the driver from being distracted and causing a safety accident. Such as the power button, volume button, etc. on mobile phones and tablets, and the buttons on game consoles, may be temporarily locked by the system in some special situations (such as during software upgrade) to avoid user operations from interrupting the process.

[0003] In the prior art, to limit and lock a button, a suitable snap ring is usually installed on the axis of the button, and the position of the snap ring is used to limit the travel of the button so that it cannot be fully pressed or popped out. This method is applicable to designs where there is enough space below the button to install the snap ring. Moreover, limited by the shape of the button, it is usually only a circular button.

[0004] All in all, when currently locking and limiting a button, it requires a large amount of space, and limited by the shape of the button, the current locking structure has low applicability. Utility Model Content

The terms "comprising", "including", "having" and their variants all mean "including but not limited to", unless otherwise specifically emphasized. "Plurality" means two or more.

[0040] In the prior art, for a circular button, a circlip is usually installed on the axis of the button to achieve limit locking of the button. However, not all buttons are circular, and the circlip occupies a large space, which is not conducive to use in some scenarios. Therefore, the applicability of the circlip is not high enough. Thus, the embodiment of this application provides a locking structure, which has a low space occupancy rate, a flexible and variable structure, can adapt to buttons of different shapes, and the applicability is greatly improved.

[0041] The embodiment of this application provides a locking structure, as Figures 1 to 7 shown, the locking structure includes a base plate 20 and a locking tongue 30;

[0042] The base plate 20 is provided with a mounting hole 200 for the button 10 to be installed therein;

[0043] The locking tongue 30 is arranged on the base plate 20. The locking tongue 30 has a connecting portion 31 and a locking portion 32. The connecting portion 31 is connected to the base plate 20, and the locking portion 32 is connected to the connecting portion 31. The locking portion 32 is used for clamping and cooperating with the limiting groove 100 on the button 10 to lock and limit the button 10;

[0044] Wherein, an operating portion 33 is further arranged on the locking tongue 30, and the locking portion 32 is moved through the operating portion 33 to lock or unlock the button 10.

[0045] The locking structure provided by the embodiment of the present application, after installing the button 10 in the mounting hole 200 on the substrate 20, is engaged with the limiting groove 100 on the button 10 through the locking tongue 30, so as to realize the locking and limiting of the button 10. Further, through the operating part 33 on the locking tongue 30, it is convenient to move the locking part 32 of the locking tongue 30, so that it is inserted into the limiting groove 100 of the button 10 to realize locking and limiting, or the locking part 32 is withdrawn from the limiting groove 100 to unlock the button 10. Compared with the snap ring limit in the prior art, the locking structure provided by the embodiment of the present application has a flexible structure (the locking tongue 30 of various different shapes can be designed), and different locking tongues 30 can be designed according to the shapes of different buttons 10, not just limited to circular buttons 10. In addition, the thickness of the locking structure is relatively thin, effectively saving internal space, having low cost, strong stability, not easy to break, and high applicability.

[0046] In application, the locking structure provided by the embodiment of the present application is mainly applied to scenarios of buttons 10, such as buttons 10 of game consoles and buttons 10 of other electronic products. The embodiment of the present application does not limit the specific application scenarios, and only takes the locking of the button 10 of the game console as an example for illustration.

[0047] The locking of the button 10 means that generally, a limiting groove 100 is provided on the side of the button 10, and the locking part 32 on the locking tongue 30 is engaged with the limiting groove 100, that is, the locking of the button 10 is realized. The unlocking of the button 10 means that the locking part 32 on the locking tongue 30 is disengaged from the engagement with the limiting groove 100, and the button 10 can move freely, that is, the unlocking of the button 10 is realized.

[0048] In some embodiments, as Figures 1 to 4 shown, the operating part 33 is provided on the locking part 32, and the operating part 33 is a through hole for inserting an operating member to move the locking part 32 to realize the locking or unlocking of the button 10. In application, the operating member can be tools such as a screwdriver and pliers. In other embodiments, as Figures 5 to 7 shown, the operating part 33 is provided on the connecting part 31, and the operating part 33 is a through hole. In a specific embodiment, if the through hole is a strip-shaped hole, a flat screwdriver can be inserted into the through hole to rotate the locking part 32 to move it into the limiting groove 100 of the button 10 to realize the locking and limiting of the button 10; or the locking part 32 is moved out of the limiting groove 100, so as to realize the unlocking of the button 10. Moreover, since the locking part 32 is located at the end far from the connection between the connecting part 31 and the substrate 20, which is equivalent to a lever, by setting the operating part 33 on the locking part 32, the force for moving the locking part 32 can be reduced according to the lever principle, and then it is convenient to quickly lock or unlock the button 10. On the other hand, the setting of the through hole can save materials, and is also beneficial to reducing the weight of the entire locking structure and increasing convenience.

[0049] In some embodiments, the operating portion 33 is a bump (not shown in the figure), and the bump is used to provide a force application point for moving the locking portion 32 to lock or unlock the button 10. Compared with the through hole, the bump can lock or unlock the button 10 only by the operator's hand without the aid of external tools.

[0050] In some embodiments, such as Figure 1 and Figure 2 shown, the substrate 20 is further provided with a first relief hole 201, the first relief hole 201 communicates with the mounting hole 200, and the locking tongue 30 is arranged on the side wall of the first relief hole 201. Thereby, the thickness of the entire locking structure can be effectively reduced, so that the locking tongue 30 and the substrate 20 are in the same plane, and the entire locking structure can be made thinner, thereby reducing the space occupied by the locking structure. Moreover, the existence of the first relief hole 201 can provide sufficient space for the moving locking tongue 30 to move, so that it can move back and forth smoothly in the relief hole and the limiting groove 100 without being hindered. In other embodiments, such as Figure 5 and Figure 6 shown, the substrate 20 is further provided with a second relief hole 202, and the second relief hole 202 communicates with the mounting hole 200. The existence of the second relief hole 202 is for the convenience of installation and disassembly of the button 10. The second relief hole 202 reserves space between the button 10 and the substrate 20, and the button 10 can be operated through the second relief hole 202, improving the convenience.

[0051] In some embodiments, such as Figure 1 and Figure 2 , one end of the connecting portion 31 is connected to the side wall of the first relief hole 201 close to the mounting hole 200, and the locking portion 32 is connected to the other end of the connecting portion 31. In this way, the position where the locking tongue 30 moves can be directly opposite to the limiting groove 100 in the button 10, and the locking portion 32 can be engaged with the limiting groove 100 with the smallest displacement.

[0052] In some embodiments, such as Figure 1 and Figure 2 shown, the thickness of the locking tongue 30 is not greater than the thickness of the substrate 20. In other words, the thickness of the locking tongue 30 in the Z direction is less than or equal to the thickness of the substrate 20 in the Z direction. This is to minimize the thickness of the entire locking structure as much as possible, and making the structure thinner can adapt to more application scenarios.

[0053] In some embodiments, such as Figure 2 and Figure 5As shown, the width of the connecting portion 31 is smaller than the width of the locking portion 32. Since the connecting portion 31 is directly connected to the substrate 20, one end of the locking portion 32 is connected to the connecting portion 31, and the other end of the locking portion 32 is a free end, that is, the movement of the locking portion 32 can be achieved by operating the operating portion 33. Setting the width of the connecting portion 31 to be smaller than that of the locking portion 32 is for two reasons. On the one hand, it is to make the connecting portion 31 easily deformable to achieve the movement of the locking portion 32; on the other hand, because the locking portion 32 needs to be engaged with the limiting groove 100 in the button 10, the width of the locking portion 32 is set larger to facilitate the engagement, which is conducive to quickly locking the button 10.

[0054] It should be noted that the thickness refers to the distance along the pressing direction of the button 10, that is, the Z direction in the figure, and the width refers to the distance in the length or width direction of the substrate 20, that is, the X or Y direction in the figure. The above is for facilitating the understanding of the technical content of this solution and should not be construed as a limitation on the scope of the embodiments of the present application.

[0055] In some embodiments, such as Figures 2 to 4 、 Figure 6 and Figure 7 As shown, the locking portion 32 has a protrusion 321 extending towards the direction close to the mounting hole 200. The existence of the protrusion 321 can effectively increase the width of the locking portion 32, thus facilitating the engagement and limiting with the limiting groove 100, which is conducive to quickly locking the button 10.

[0056] In some embodiments, the substrate 20 and the locking tongue 30 are an integral structural member, and the connecting portion 31 and the locking portion 32 are an integral structural member. The meaning of the integral structural member is that the substrate 20 and the locking tongue 30, and the locking portion 32 and the connecting portion 31 in the locking tongue 30 are all integrally formed, which is conducive to improving the overall stability of the locking structure.

[0057] In application, the material of the entire locking structure is sheet metal, and the specific material can be materials such as metals and alloys. The materials are cheap and easy to obtain, with good economic benefits and are conducive to large-scale production and application.

[0058] In some embodiments, such as Figure 2 and Figure 3 As shown, a fixing member 21 is provided on the side of the substrate 20, and the fixing member 21 is provided with a fixing hole 210 for connecting with a fastener to fix the locking structure. The fasteners include but are not limited to screws, bolts, etc.

[0059] In some embodiments, such as Figures 1 to 4 As shown, there are multiple locking tongues 30, and the multiple locking tongues 30 are evenly distributed along the circumferential side of the mounting hole 200. In this way, the locking and limiting of the button 10 can be strengthened. Specifically, as Figures 1 to 4As shown, for the triangular button 10, three locking tongues 30 are provided, and the three locking tongues 30 are provided corresponding to the three corners of the triangular button 10. In other embodiments, they can also be provided corresponding to the three sides of the triangular button 10.

[0060] As Figures 5 to 7 shown, for the circular button 10, four locking tongues 30 can be provided, and the four locking tongues 30 are evenly distributed along the periphery of the button 10, which can effectively improve the locking effect on the button 10. In other embodiments, the button 10 can also be of other shapes, and the same locking tongues 30 can be provided corresponding to the shape of the button 10, so that the applicability of the locking structure can be effectively improved.

[0061] In some embodiments, there are multiple mounting holes 200, and multiple locking tongues 30 are provided. One locking tongue 30 is provided corresponding to one mounting hole 200, or multiple locking tongues 30 are provided corresponding to one mounting hole 200. As Figures 5 to 7 shown, two mounting holes 200 are provided. At this time, two buttons 10 can be locked and limited simultaneously, and each mounting hole 200 corresponds to 4 locking tongues 30. In other embodiments, one mounting hole 200 can correspond to other numbers of locking tongues 30, such as 1, 2, 3, etc.

[0062] The locking structure provided by this application has the following advantages:

[0063] 1. The structure is flexible and variable, and various different shapes of locking tongues 30 can be designed, not only applicable to the circular button 10, but also applicable to triangular and other irregularly shaped buttons 10;

[0064] 2. The thickness of the entire locking structure is thin, saving internal space. Especially, the large-size locking structure is much thinner than the commonly used circlips, increasing the application scenarios of the locking structure;

[0065] 3. The materials are cheap and easily available, with low cost, and can be mass-produced and applied;

[0066] 4. The overall stability is strong and it is not easy to break.

[0067] In the above embodiments, the descriptions of each embodiment have their own emphases. For parts not detailed or recorded in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0068] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
