Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a switch mounting base and switch assembly. Background Technology

[0002] In electronic devices, home appliances, and various mechanical control devices, push-button switches are a crucial operating element, and the performance of their mounting base has a vital impact on the stability and lifespan of the entire switch.

[0003] Currently, most push-button switches use metal bases. Metal bases, with their superior strength and stability, can effectively withstand the various pressures and impacts generated during frequent use, ensuring the switch's proper function. However, these metal bases also have some significant drawbacks. Firstly, the high density of metal results in a relatively high weight, which is a significant disadvantage for applications with stringent requirements for lightweight equipment. Secondly, the relatively high material cost of metal increases the overall cost of the product.

[0004] In addition, some push-button switch mounting bases are made of plastic. Plastic bases offer significant advantages such as light weight and low processing costs, effectively reducing the overall weight and production cost of the product, thus providing an advantage in cost- and weight-sensitive applications. However, plastic has relatively low strength and poor durability. Over long-term use, plastic bases are prone to deformation and damage, leading to insecure button switch mounting and affecting its normal operation. Especially in high-intensity applications, such as industrial control equipment and frequently operated appliances, the lifespan of plastic mounting bases often fails to meet requirements, necessitating frequent replacements. This not only increases maintenance costs but also causes considerable inconvenience for users.

[0005] In summary, existing push-button switch mounting bases have limitations in material selection, failing to simultaneously meet requirements for high strength, lightweight, low cost, and long service life. Therefore, developing a novel mounting base structure to overcome these shortcomings is particularly urgent and necessary.

[0037] Figure 1 A schematic diagram of a fixing base 100 according to an embodiment of the present invention is shown. Figure 2 An exploded view of a fixed base 100 according to an embodiment of the present invention is shown below, in conjunction with... Figure 1 and Figure 2 Provide a detailed description.

[0038] like Figure 1 and Figure 2 As shown, the fixed base 100 mainly includes a metal insert 110 and a non-metal frame 120. The non-metal frame 120 covers the outside of the metal insert 110. By adopting a design that combines the non-metal frame 120 with the metal insert 110, the structural strength of the fixed base 100 is ensured, while the overall weight and cost are reduced. Figure 3a and Figure 3b Schematic diagrams of a metal insert 110 according to one embodiment of the present invention are shown. Figure 3a and Figure 3bAs shown, the metal insert 110 includes a first connecting portion 111, a second connecting portion 112, and a third connecting portion 113. The first connecting portion 111 is generally annular, and a first connecting hole 114 is provided at its center for connecting the fixed base 100 to the switch. The second connecting portion 112 and the third connecting portion 113 are respectively located outside the first connecting portion 111. The second connecting portion 112 has a second connecting hole 115 for connecting the fixed base 100 to the panel (mounting plate); the third connecting portion 113 has a third connecting hole 116 for connecting the fixed base 100 to the contact block 230. Figure 2 , Figure 3a and Figure 3b As shown, a first through hole 121, a second through hole 122, and a third through hole 123 are provided on the non-metallic frame 120. The first through hole 121 is aligned with the first connecting hole 114, the second through hole 122 is aligned with the second connecting hole 115, and the third through hole 123 is aligned with the third connecting hole 116. In some embodiments, the first through hole 121 and the third through hole 123 can communicate with each other (e.g., ...). Figure 2 (As shown).

[0039] Figure 4 A schematic diagram of a fixed base 100 and a switch 210 according to one embodiment of the present invention is shown. Figure 4 As shown, multiple snap fasteners 117 are provided on the wall of the first connecting hole 114, and these snap fasteners 117 are spaced apart along the circumference of the first connecting hole 114. In specific embodiments, these snap fasteners 117 can be designed as circular protrusions, rectangular protrusions, etc. In other embodiments, only one snap fastener 117 may be provided on the wall of the first connecting hole 114. This utility model does not limit the specific number and shape of the snap fasteners 117, and can be flexibly adjusted according to the actual application scenario to achieve the best fixing effect and structural stability. Figure 4 As shown, switch 210 can be a push-button switch, rotary switch, etc. The following description uses a push-button switch as an example. Several slots 211 are provided on the side of switch 210. Each slot 211 includes a horizontal slot 211a and a vertical slot 211b that are interconnected. The vertical slot 211b extends downwards to the lower end face of switch 210. After inserting the lower end of switch 210 into the first connecting hole 114, the latch 117 can be engaged with the horizontal slot 211a by rotating switch 210, thereby achieving a secure connection between switch 210 and the fixed base 100.

This design can also achieve a latching connection between base 100 and switch 210.

[0040] According to one embodiment of the present invention, such as Figure 3a and Figure 3b As shown, the second connecting hole 115 can be a threaded hole, penetrating both the first and second sides of the metal insert 110. Preferably, the second connecting hole 115 adopts a countersunk hole (stepped hole) design, which allows the screw head to be embedded in the countersunk hole after the screw is screwed into the second connecting hole 115, thereby achieving a flat installation of the screw and preventing the screw head from protruding from the fixing base 100. Preferably, the wall thickness of the second connecting hole 115 is not less than 2mm to ensure that the second connecting part 112 has sufficient structural strength to meet the preload requirements of the screw. In some embodiments, the second connecting hole 115 is inclined relative to the first connecting hole 114, that is, the axis of the second connecting hole 115 and the axis of the first connecting hole 114 form a preset included angle α (α>0), to facilitate the user to connect the fixing base 100 and the panel with screws.

[0041] According to one embodiment of the present invention, such as Figure 3a and Figure 3b As shown, the third connecting hole 116 can be a threaded hole.

By designing the third connecting hole 116 as a blind hole, it can serve as a foolproof method, preventing users from using the third connecting hole 116 to connect the fixed base 100 to the panel.

[0042] According to one embodiment of the present invention, such as Figure 3a and Figure 3b As shown, two second connecting portions 112 and two third connecting portions 113 are provided. The two second connecting portions 112 are symmetrically arranged on the left and right sides of the first connecting portion 111, and the two third connecting portions 113 are symmetrically arranged on the front and rear sides of the first connecting portion 111. By symmetrically arranging two second connecting portions 112 on the left and right sides of the first connecting portion 111, the connection stability between the fixed base 100 and the panel is significantly enhanced, ensuring a tight and reliable connection under various stress conditions. By symmetrically arranging two third connecting portions 113 on the front and rear sides of the first connecting portion 111, the fixed base 100 can simultaneously achieve a stable connection with two contact blocks, providing a reliable structural foundation for realizing more complex electrical connection functions.

[0043] Those skilled in the art will readily understand that the second connecting portion 112 and the third connecting portion 113 can also be provided in three, four, or more forms, with multiple second connecting portions 112 and multiple third connecting portions 113 alternately arranged along the circumferential direction of the first connecting portion 111. Preferably, a reinforcing rib 118 is provided between adjacent second connecting portions 112 and third connecting portions 113 to improve the structural strength of the metal insert 110 and the fixed base 100, enabling the fixed base 100 to easily withstand greater and more frequent pressure and impact. More preferably, the wall thickness of the reinforcing rib 118 is not less than 1 mm.

[0044] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, one or more weight-reducing holes 124 are provided on the non-metallic frame 120 to reduce the weight and material cost of the non-metallic frame 120 (fixed base 100).

[0045] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the non-metallic frame 120 can be made of plastic material. Preferably, the non-metallic frame 120 can be formed on the outside of the metal insert 110 using processes such as injection molding or 3D printing. In other embodiments, the non-metallic frame 120 can also be made of materials such as rubber; this invention is not limited to the above material choices.

[0046] Figure 5 A schematic diagram of a switch assembly 200 according to an embodiment of the present invention is shown below, in conjunction with... Figure 5 Provide a detailed description.

[0047] like Figure 5 As shown, the switch assembly 200 may include a first screw 220, a mounting base 100 as described above, and a switch 210. The switch 210 is inserted into the first connection hole 114 of the mounting base 100 and snaps into the mounting base 100. The first screw 220 is disposed in the second connection hole 115 of the mounting base 100, and the mounting base 100 can be stably fixed to the panel by means of the first screw 220.

[0048] According to one embodiment of the present invention, the switch assembly 200 may further include a contact block 230, which is coupled to the switch 210. When the switch 210 is pressed, the conductive contacts in the contact block 230 come into contact with each other, thereby closing the circuit. When the switch 210 is released, the conductive contacts in the contact block 230 separate from each other, and the circuit is broken. Preferably, the switch assembly 200 further includes a second screw 240, which is disposed in the third connecting hole 116 of the fixing base 100 and connects the fixing base 100 and the contact block 230 to ensure a stable connection between the switch 210 and the contact block 230.

[0049] Compared with existing technologies, the embodiments of this utility model provide a fixed base 100 and a switch assembly 200 for a switch 210. By adopting a design combining a non-metallic frame 120 and a metal insert 110, this utility model significantly reduces the overall weight and cost of the fixed base 100 while ensuring structural strength, meeting the lightweight requirements of modern electronic devices and enabling reliable installation under various complex working conditions. The metal insert 110, as the core component of the fixed base 100, ensures the structural strength and stability of the fixed base 100, allowing it to easily withstand greater and more frequent pressure and impact. This effectively solves the problem of easy deformation and damage caused by insufficient strength in existing plastic bases, significantly improving the durability and reliability of the switch 210 under high-intensity usage scenarios. Simultaneously, the use of the non-metallic frame 120 reduces the amount of metal material used, effectively reducing production costs without sacrificing performance, improving the product's cost-effectiveness, and providing a more competitive solution for the widespread application of the switch 210.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
