Description

Technical Field

[0001] The utility model relates to the technical field of buttons, and specifically relates to a durable button assembly. Background Art

[0002] In the design of household induction cookers, traditional circular coil springs are commonly used for the rebound function of buttons, that is, the buttons are pushed up by the elastic force of the springs to contact the surface crystal plate. In the working environment of induction cookers, frequent heating and cooling lead to large temperature changes. This will cause the elastic force of the springs to gradually weaken or become uneven, thereby affecting the normal rebound and pressing effect of the buttons. Over time, the material and structure of the springs may undergo slight deformations, resulting in uneven resilience of the springs, thus causing local button protrusions or depressions. If the surface crystal plate of the button is subjected to uneven pressure, it may deform, affecting the touch and button usage effects. Content of the Utility Model

[0004] To achieve the above purpose, the utility model provides the following technical solution: A durable button assembly, comprising:

[0005] A bracket with mounting holes provided at the top;

[0006] A button assembly, the button assembly is placed on the top of the bracket, the button assembly includes a display board fixing box, a fixing hook plate slidably connected to the mounting holes is installed at the bottom of the display board fixing box, a spring piece is detachably installed at the bottom of the fixing hook plate, and one end of the spring piece is slidably connected to the bracket to ensure uniform force on the display board fixing box.

[0007] Preferably, the mounting holes are in a rounded rectangular structure, and positioning columns slidably connected to the mounting holes are fixedly connected to both sides of the bottom of the display board fixing box and located on both sides of the fixing hook plate, and the positioning columns are in a semi-circular structure.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , 2, as shown in Figures 3, 4, 5, and 6, the present utility model provides a technical solution: a durable button assembly, including: a bracket 1 with a mounting hole 14 opened at the top; the button assembly is placed on the top of the bracket 1, the button assembly includes a display board fixing box 8, a fixing hook plate 10 fixedly installed at the bottom of the display board fixing box 8 and slidably connected to the mounting hole 14, a spring piece 2 can be connected to the bottom of the fixing hook plate 10, and one end of the spring piece 2 is slidably connected to the bracket 1, which is used to ensure that the display board fixing box 8 is evenly stressed.

[0022] It should be noted that in this embodiment, the fixing hook plate 10 is inserted into the interior of the mounting hole 14, and the end of the fixing hook plate 10 is hooked on the bottom of the mounting hole 14. Six spring pieces 2 are equidistantly arranged at the bottom of the display board fixing box 8, which are used to lift the display board fixing box 8 to the top of the bracket 1. The height of the fixing hook plate 10 is less than the height of the spring piece 2. After installation, the spring piece 2 is always in a compressed state, so as to prevent the display board fixing box 8 from loosening. The spring piece 2 is an integral structure, and under the action of metal elasticity, it prevents the occurrence of thermal expansion and contraction, avoids uneven stress on the display board fixing box 8, and prevents the occurrence of local button protrusion and depression, resulting in button failure.

[0023] In one embodiment, the mounting hole 14 is a rounded rectangular structure, and positioning columns 9 slidably connected to the mounting hole 14 are fixedly connected to both sides of the bottom of the display board fixing box 8 and located on both sides of the fixing hook plate 10, and the positioning columns 9 are semi-circular structures.

[0024] It should be noted that in this embodiment, the positioning column 9 is slidably connected to the mounting hole 14, and the semi-circular structure enables the positioning column to fit more precisely with the mounting hole. The semi-circular structure ensures that the positioning column can smoothly enter the mounting hole, and at the same time avoids the jamming phenomenon caused by shape mismatch. The two positions of the positioning column 9 (located on both sides of the fixing hook plate) are evenly distributed, and in the case where the mounting hole 14 is slidably connected to the fixing hook plate 10, the stability of the button assembly is further enhanced, ensuring that the assembly does not tilt during use.

[0025] In one embodiment, the spring piece 2 includes a bottom frame 12 with a U-shaped structure, a spring piece 13 is obliquely fixedly connected to the middle of the bottom frame 12, the spring piece 13 is slidably connected to the bracket 1, and a limiting groove 11 for limiting the bottom frame 12 is fixedly connected to the bottom of the display board fixing box 8. The limiting groove 11 is an L-shaped structure, and three limiting grooves 11 are distributed in a "pin" shape structure.

[0026] It should be noted that in this embodiment, the bottom frame 12 is slid into the limiting groove 11 from one end of the three limiting grooves 11. The limiting groove 11 and the bottom frame 12 are in interference fit, so as to ensure that the bottom frame 12 is fixedly installed in the limiting groove 11. The U-shaped bottom frame structure enables the spring piece 2 to have better structural strength, can effectively support the elastic piece 13, and ensures that the elastic piece 13 will not deform or fall off when受力, ensuring that the display board fixing box 8 can be evenly stressed.

[0027] It should be noted that in this embodiment, the three limiting grooves 11 are distributed in a "pin" - shaped structure, so that the bottom frame 12 can be supported from multiple directions after installation, effectively preventing it from shifting or shaking, and enhancing the overall structural stability. The interference fit between the limiting groove 11 and the bottom frame 12 further ensures that the bottom frame 12 can be firmly fixed in the limiting groove, avoiding loosening or dislocation of the bottom frame due to vibration or external force.

[0028] In one embodiment, a display board 3, a lamp board 4, a lamp board fixing box 5, and a touch board 6 are sequentially arranged from bottom to top inside the display board fixing box 8. A positioning connection column 7 is fixedly connected inside the display board fixing box 8. The display board 3, the lamp board 4, the lamp board fixing box 5, and the touch board 6 are all provided with holes that cooperate with the positioning connection column 7.

[0029] It should be noted that in this embodiment, the positioning connection column 7 plays the role of positioning and connecting each component, ensuring that the display board 3, the lamp board 4, the lamp board fixing box 5, and the touch board 6 can be fixed and coordinated at precise positions. The positioning column provides support for each component and enables each component to be precisely aligned, avoiding malfunction or mechanical failure caused by inaccurate component positions.
