Description

Technical Field

[0001] The present application relates to the field of household appliance technology, for example, to a button cap fixing device and a television. Background Art

[0002] The electrical switches currently on the market, especially those used on televisions, have complex switch structures and are inconvenient to install. Generally, a structure in which a button and a TV housing are integrated is adopted. For example, a TV button structure includes a housing and a circuit board fixed to the inner side of the housing. The housing is provided with a button integrally formed therewith. The button includes a button body and a connecting rib provided on the side of the button body for connecting to the housing. The button body is separated from the housing. However, since the button, the connecting rib and the housing are integrally formed, if the button or the connecting rib is damaged during use, it is difficult to perform subsequent repairs.

[0003] In the related art, the buttons and the TV housing are designed to be separated, and the buttons are installed on the TV housing by screws, adhesive bonding and riveting. However, since screws need to occupy a space of a certain depth, adhesive bonding requires a sufficient contact area on the buttons and is prone to the risk of debonding, riveting is prone to damage to the riveted points during later disassembly.

[0004] Therefore, it can be seen that how to facilitate the later repair of the buttons while reducing their occupation of installation space, improving their installation firmness, and reducing the risk of damage has become a technical problem that needs to be urgently solved by technical personnel in this field.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0045] Combination Figure 1 , 2 As shown, an embodiment of the present disclosure provides a key cap fixing device for mounting the key cap on a housing 100, comprising: a key cap body 200, an elastic arm 300, and a snap-fit ​​structure 400, wherein the elastic arm 300 is connected to the key cap body 200; the snap-fit ​​structure 400 is disposed between the elastic arm 300 and the housing 100, and is used for fixing the elastic arm 300 on the housing 100.

[0046] A key cap fixing device according to an embodiment of the present disclosure is used, and the elastic arm 300 is fixed to the housing 100 through the buckle structure 400. The buckle stability is high, which can improve the reliability of the connection between the key cap body 200 and the housing 100. The buckle structure 400 has a high structural strength of the buckle part, which can effectively reduce the risk of damage. The buckle structure 400 is detachable and snap-connected. This design not only improves the flexibility of the connection, but also makes the installation and maintenance process more convenient. The user can easily disassemble the damaged parts for replacement or repair, which reduces the cost and time of repair. The structure between the elastic arm 300 and the snap structure 400 is relatively compact and can be closely attached to the inner wall of the casing 100, occupying little space, making the layout of the entire device on the casing 100 more reasonable. Combined with the above, this solution can facilitate the later repair of the key while reducing its occupation of installation space, improving its installation firmness, and reducing the risk of damage. In addition, the key cap body 200 is connected to the elastic arm 300, and the elasticity of the elastic arm 300 can provide the key cap body 200 with a reset elastic force, so that the key cap body 200 has a good touch and feedback during use.

[0047] Optionally, both sides of the key cap body 200 are respectively connected to the elastic arms 300. In this way, the elastic arms 300 can be used to provide elastic force on both sides of the key cap body to maintain the overall force balance of the key cap body, thereby improving the stability during operation.

[0048] Optionally, the elastic arms 300 are symmetrically distributed on both sides of the center line of the key cap body 200. This ensures that when the key cap body 200 is subjected to pressure, the elastic arms 300 can give equal elastic force to both sides of the key cap body 200; this equal elastic force distribution effectively avoids the key cap body 200 from deflecting or shaking during the pressing process, thereby further improving the accuracy and stability of the key operation.

[0049] Combination Figure 2As shown, optionally, the snap structure 400 includes: a locking portion 410 and an anti-slip portion 420; the locking portion 410 is arranged between the elastic arm 300 and the housing 100, and is used to limit the movement of the elastic arm 300 relative to the housing 100 in a first direction; the anti-slip portion 420 is arranged between the elastic arm 300 and the housing 100, and is used to limit the movement of the elastic arm 300 relative to the housing 100 in a second direction, wherein one of the first direction and the second direction is perpendicular to the pressing and resetting direction of the key cap body 200, and the other is parallel to the pressing and resetting direction of the key cap body 200. In this way, one of the locking portion 410 and the anti-slip portion 420 limits the elastic arm 300 in the direction parallel to the pressing and resetting direction of the key cap body 200, which can prevent the key cap body 200 from driving the end of the elastic arm 300 connected to the housing 100 to move along the pressing direction of the key cap body 200 when subjected to pressing force, thereby keeping one end of the elastic arm 300 more stably fixedly connected to the housing 100; and the other of the locking portion 410 and the anti-slip portion 420 can limit the elastic arm 300 in the direction perpendicular to the pressing and resetting direction of the key cap body 200, which can prevent the elastic arm 300 from moving in the direction perpendicular to the pressing and resetting direction of the key cap body 200, thereby preventing the structure for limiting the elastic arm 300 in the direction parallel to the pressing and resetting direction of the key cap body 200 from falling off by itself. The two complement each other and limit each other, which can further improve the firmness of the connection between the elastic arm 300 and the housing 100.

[0050] Optionally, the elastic arm 300 extends as a whole to one side of the key cap body 200, and the locking portion 410 is closer to the key cap body 200 relative to the anti-detachment portion 420, wherein the locking portion 410 is used to limit the movement of the elastic arm 300 relative to the housing 100 in a direction perpendicular to the pressing and resetting of the key cap body 200, and the anti-detachment portion 420 is used to limit the movement of the elastic arm 300 relative to the housing 100 in a direction parallel to the pressing and resetting of the key cap body 200. In this way, the point where the elastic arm 300 is completely locked in the direction of pressing and resetting parallel to the key cap body 200 is farther away from the key cap body 200, and the locking portion 410 only limits the movement of the elastic arm 300 relative to the housing 100 in the direction of pressing and resetting perpendicular to the key cap body 200. The elastic arm 300 corresponding to its setting position has a certain amount of activity in the direction of pressing and resetting parallel to the key cap body 200. Therefore, the entire section of the elastic arm 300 from the anti-detachment portion 420 to the key cap body 200 can play an elastic role. Compared with the solution in which the locking portion 410 limits the elastic arm 300 in the direction of pressing and resetting parallel to the key cap body 200, the length of the entire elastic arm 300 can be set shorter while meeting the elastic force requirements, which is more conducive to reducing the overall space occupancy.

[0051] Combination Figure 2As shown, optionally, the locking portion 410 includes: an insertion piece 411 and an insertion slot 412, wherein the insertion piece 411 is arranged on the elastic arm 300; the insertion slot 412 is arranged on the inner wall of the housing 100, and the insertion piece 411 is detachably fixed in the insertion slot 412. In this way, the insertion piece 411 can be inserted into the insertion slot 412 for detachable assembly, and the insertion piece 411 can be firmly fixed therein by using the insertion slot 412, and is not easy to fall off; not only the position limit of assembly is achieved, but also the assembly process becomes simple and fast, which greatly saves the installation time; the connection between the insertion piece 411 and the insertion slot 412 is detachable, which means that when maintenance or replacement of parts is required, the corresponding operation can be completed by simply removing the insertion piece 411, without the need for complicated disassembly and reassembly processes, which improves the convenience of maintenance while also reducing the maintenance cost.

[0052] It can be understood that the plug-in piece 411 is a side convex structure set on the elastic arm 300, and a protruding boss is provided on the casing 100, and a plug-in groove 412 adapted to the plug-in piece 411 is provided on the boss, or the plug-in groove 412 is defined between the boss and the inner wall of the casing 100, and the plug-in groove 412 is a through opening, which facilitates the plug-in piece 411 to slide into the plug-in groove 412.

[0053] Combination Figure 2 As shown, the anti-detachment part 420 optionally includes: a base 421 and a locking member 422, wherein the base 421 is arranged on the housing 100; the locking member 422 is arranged on the elastic arm 300, and the locking member 422 is detachably connected to the base 421. In this way, the base 421 can be stably and reliably connected to the locking member 422; the locking member 422, as a key connecting member, can be easily disassembled and connected to the base 421; this design makes the assembly process simple and fast, without the need to use complex tools or perform cumbersome operations, thereby greatly saving installation time; in addition, since the locking member 422 is detachable, when maintenance or replacement of parts is required, it can be easily disassembled and then reconnected to the base 421, which not only improves the convenience of maintenance, but also reduces maintenance costs.

[0054] Optionally, the base 421 is a protrusion protruding from the housing 100, and a first interference surface is provided on the protrusion. The locking member 422 is a groove-shaped structure on the elastic arm 300, and a second interference surface is provided on the groove-shaped structure. The first interference surface and the second interference surface can be adapted to contact and interfere with each other, thereby locking the locking member 422 and the base 421. In this way, the mutual interference between the first interference surface and the second interference surface can be used to effectively fix the base 421 and the locking member 422, and the use of the interference surface for fixing, in the absence of other external forces, is firmly fixed and not easy to disengage, and when the user actively operates, the first interference surface and the second interference surface can be more conveniently disengaged, thereby improving the convenience of disassembly.

[0055] Among them, the plug-in slot 412 and the base 421 can be designed separately and then fixed to the housing 100 by means of screw connection, snap-fit ​​connection, adhesive connection or rivet connection. This design allows the plug-in slot 412 and the base 421 to be produced and processed as an independent component, and the size, shape and performance of the plug-in slot 412 and the base 421 can be adjusted according to actual needs to meet the requirements of different models and button layouts. At the same time, the separately designed plug-in slot 412 and base 421 are also more convenient during maintenance and replacement. Only a single component needs to be disassembled and installed, and the entire housing 100 does not need to be disassembled.

[0056] Alternatively, the plug slot 412 and the base 421 are integrally formed with the housing 100. This design makes the plug slot 412 and the base 421 a part of the housing 100, and is directly formed together with the housing 100 through processes such as injection molding and die casting. This integrated design not only simplifies the production process and reduces costs, but also improves the structural strength and stability of the entire machine. No additional connecting accessories are required between the integrally formed plug slot 412 and base 421 and the housing 100, which reduces the risk of assembly errors and looseness and improves the reliability of fixing the elastic arm 300.

[0057] Optionally, the plug-in piece 411 and the locking piece 422 are an integral structure with the elastic arm 300, and are formed by bending the elastic arm 300. In this way, the one-piece design makes the entire structure more concise and compact, reduces the number of components, and simplifies the assembly process; since the plug-in piece 411, the locking piece 422 and the elastic arm 300 are all continuously bent from the same material, no additional connection or fixation is required, so the manufacturing process is more convenient and quick; in addition, the one-piece design also brings about a significant reduction in manufacturing costs; due to the reduction in the number of components and the simplification of the manufacturing process, the production efficiency is improved, and at the same time, the material waste is effectively controlled, thereby improving the market competitiveness of the product.

[0058] Combination Figure 3 As shown, optionally, a warping edge 423 is provided on the locking member 422. Thus, when the user needs to engage or disassemble the elastic arm 300 and the anti-detachment portion 420, the user only needs to gently hold or warp the warping edge 423 to effectively control the elastic arm 300; this design not only simplifies the operation steps, but also reduces the difficulty of operation, so that the user can complete the relevant operations more quickly and accurately.

[0059] At the same time, in order to ensure that the warped edge 423 has a good touch and anti-skid performance, an anti-skid pattern or an anti-skid layer is provided on the surface of the warped edge 423. This allows the user to stably grasp the warped edge 423 even in a sweaty or slippery environment to avoid operating errors.

[0060] Optionally, when the locking member 422 is in close contact with the side wall of the housing 100, the warped edge 423 extends or protrudes relative to the locking member 422 in a direction away from the side wall of the housing 100. In this way, when the locking member 422 is adapted to be connected with the base 421 and in close contact with the side wall of the housing 100, a gap is formed between the warped edge 423 and the housing 100, and the gap is provided for the user to insert a finger, so that the user can operate the warped edge 423 to separate the locking member 422 from the base 421.

[0061] Combination Figure 3 As shown, optionally, the elastic arm 300 includes: a rebound portion 310 and a bent portion 320, one end of the rebound portion 310 is connected to the key cap body 200 and extends toward one side of the key cap body 200, the bent portion 320 is connected to one end of the rebound portion 310, and is bent relative to the rebound portion 310 toward the pressing and reset direction parallel to the key cap body 200, wherein the buckle structure 400 is disposed on the bent portion 320. In this way, the entire elastic arm 300 can be bent, so that the elastic arm 300 as a whole can be fixed on two planes at an angle to each other, thereby improving the firmness of its fixation.

[0062] Combination Figure 4 , 5 As shown, in order to adapt to the installation of the elastic arm 300, the housing 100 is configured to include: a key installation surface 101 and an elastic arm fixing surface 102; the key installation surface 101 is provided with a mounting hole 103, and a portion of the key cap body 200 can be adapted to pass through the mounting hole 103; the elastic arm fixing surface 102 is adjacent to the key installation surface 101 and has a set angle therebetween, and the set angle is the same as the angle at which the bending portion 320 is bent relative to the rebound portion 310. In this way, the rebound portion 310 and the bending portion 320 of the elastic arm 300 are arranged in different planes, so that one end of the elastic arm 300 can be better fixed and its stability can be improved.

[0063] Alternatively, the angle is set to be slightly larger than the angle at which the bending portion 320 is bent relative to the rebound portion 310. It can be understood that setting the angle to be slightly larger than the angle at which the bending portion 320 is bent relative to the rebound portion 310 means that the difference between the angle set to be larger than the angle at which the bending portion 320 is bent relative to the rebound portion 310 is less than or equal to 5 degrees. In this way, setting the angle slightly larger can make the elastic arm 300 close to the key installation surface 101 and the elastic arm fixing surface 102, so that the elastic arm fixing surface 102 can be in close contact with the rebound portion 310, and the rebound portion 310 has elastic potential energy in the direction of the elastic arm fixing surface 102, so that the key cap body 200 can be more timely subjected to the force in the reset direction, thereby improving the user's sensory experience of pressing.

[0064] like Figure 3As shown, optionally, the elastic arm 300 is formed by bending a strip-shaped structure as a whole, and the bending portion 320 includes: a first bending portion 321, a second bending portion 322, a first straight section 323, a third bending portion 234, a second straight section 325 and a fourth bending portion 326. The first bent portion 320 is connected to one end of the rebound portion 310 and is bent toward a side parallel to the pressing and resetting direction of the key cap body 200, the second bent portion 322 is connected to the first bent portion 321 and is bent toward a side perpendicular to the rebound portion 310 and the pressing and resetting direction of the key cap body 200, the first straight section 323 is connected to the second bent portion 322, the third bent portion 234 is connected to the first straight section 323 and is bent toward a direction parallel to the pressing and resetting direction of the key cap body 200, the second straight section 325 is connected to the third bent portion 234, the fourth bent portion 326 is connected to the second straight section 325, wherein the first straight section 323 acts as the plug-in piece 411, and the fourth bent portion 320 acts as the locking piece 422. In this way, the bent shape of the bent portion 320, the plug-in piece 411 and the tightening piece can all be formed by a part of the bent portion 320, which can further improve the integrity of the product and make the whole more solid.

[0065] Optionally, the elastic arm 300 includes two groups of rebound portions 310 and two groups of bending portions 320, and the two groups of rebound portions 310 and the two groups of bending portions 320 are symmetrically distributed about the center line of the key cap body 200, and the fourth bending portion 326 of one group and the fourth bending portion 326 of the other group are connected to each other to form a whole. In this way, the two groups of rebound portions 310 and the two groups of bending portions 320 distributed in pairs can more firmly fix the key cap body 200 and improve the overall stability.

[0066] Optionally, the elastic arm 300 is an integrally formed structure. In this way, the overall structure can be more stable and easy to produce, and can be produced in an integrated manner by injection molding or stamping, thereby reducing production costs.

[0067] Optionally, one end of the rebound portion 310 is bent toward the location where the mounting hole 103 is set. This provides elastic force in a certain reset direction when the key cap body 200 is not pressed, preventing the key cap from moving and increasing the pressing feel. The inner wall of the housing 100 is a plane, and the rebound portion 310 is pressed straight by the inner wall of the housing 100 when the key cap body 200 is installed, so that the rebound portion 310 applies pressure to the key cap body 200.

[0068] like Figure 6 , 7As shown in FIG. 8 , optionally, the key cap fixing structure further includes: a guide member 500, which is disposed between the key cap body 200 and the housing 100 and is used to limit the key cap body 200 to move in the pressing and resetting directions. In this way, the restraining force of the guide member 500 on the movement of the key cap body 200 can be used to improve the stability of the movement of the key cap body 200.

[0069] The material of the guide member 500 may be plastic, which ensures sufficient strength and wear resistance while avoiding excessive friction resistance to key operations, thereby improving the user experience.

[0070] Optionally, the guide member 500 includes a slide rail 501 and a slide groove 502, wherein the slide groove 502 is adapted to the slide rail 501 and is limited to slide along the slide rail 501, wherein one of the slide rail 501 and the slide groove 502 is disposed on the housing 100 and the other is disposed on the key cap body 200. The slide groove 502 can maintain the cooperation with the slide rail 501 when the key cap body 200 is pressed, so as to ensure that the key cap body 200 moves along the track of the slide rail 501.

[0071] Optionally, the slide rail 501 is connected to the housing 100, and the slide groove 502 is provided on the key cap body 200. Since the thickness of the housing 100 is limited, the housing 100 needs to be partially thickened to provide the slide groove 502. Relatively speaking, the structure of providing the slide rail 501 on the housing 100 is easier to implement and has lower cost.

[0072] As an optional implementation, a protrusion structure is provided on the button cap body 200, and the slide groove 502 is provided on the protrusion structure. The slide rail 501 is provided at a position on the housing 100 corresponding to the slide groove 502, and is an integrally formed structure with the housing 100. The slide rail 501 is a rectangular protrusion, and the slide groove 502 is a rectangular groove body. Alternatively, the slide rail 501 is cylindrical or semi-cylindrical, and the slide groove 502 is arc-shaped. In this way, the structure is stable and easy to implement.

[0073] Combination Fig. 9As shown, optionally, the key cap body 200 includes a decorative piece 201, a connecting piece 202, and a rear convex piece 203, the connecting piece 202 is connected to the elastic arm 300, and the decorative piece 201 and the rear convex piece 203 are respectively arranged on both sides of the connecting piece 202. The connecting piece 202 and the decorative piece 201 can be bonded or clamped to meet the requirements of different models. This design enables the key cap to be flexibly applied to various models, reduces production costs, and improves the market competitiveness of the product. In addition, the design of the rear convex piece 203 effectively reduces the stroke of the key cap body 200 when pressed and moved. By adjusting the size and shape of the rear convex piece 203, the size of the switch 105 of different models can be adapted, thereby ensuring that accurate pressing operations can be achieved on different models. This design not only improves the user's operating accuracy, but also reduces the possibility of misoperation and improves the user experience.

[0074] The connecting member 202 is a circular sheet structure, and the rear protrusion 203 is a cross-shaped protrusion and is arranged on one side of the connecting member 202. The decorative member 201 is a circular button, which can be detachably installed on the other side of the connecting member 202. Of course, according to actual needs, the connecting member 202 and the decorative member 201 can also be square or other shapes, which mainly depends on the shape of the required button.

[0075] Combination Fig.10 As shown, an embodiment of the present disclosure provides a television set, comprising the key cap fixing device described in any of the above embodiments, and having the technical effects of the key cap fixing device.

[0076] Optionally, the television includes: a housing 100, a circuit board 104, the circuit board 104 is arranged in the housing 100, and a switch 105 is arranged on the circuit board 104. When the key cap body 200 is pressed, the switch signal generated by it can be quickly and accurately captured by the switch 105, and the switch 105 then efficiently converts these mechanical signals into electrical signals required by the circuit board 104. Through this design, the present application successfully realizes the rapid and accurate conversion of the switch signal pressed by the key cap body 200 to the electrical signal required by the circuit board 104, which not only improves the response speed of the device, but also enhances the stability and reliability of the device. In addition, due to the integrated design of the switch 105 and the circuit board 104, the structure of the entire system is more compact, which is conducive to realizing the lightweight design of the device.
