[0002] Taking a two-stage push-button switch as an example, existing electrical equipment generally uses two-stage push-button switches, but at present, two-stage push-button switches often face the problem of overheating during use.

[0003] On the one hand, the electrical contacts inside the two-stage push-button switch generate a lot of heat; on the other hand, the two-stage push-button switch has a high pressing frequency and a limited heat dissipation area, and frequent switching operations will further amplify the risk of heat accumulation.

[0004] Existing two-stage push-button switch assemblies are mainly made of traditional metal materials and have a closed structure, which prevents heat from dissipating quickly, thus shortening the switch life and increasing safety hazards. Utility Model Content

[0022] Wherein, the trigger stroke between the first elastic conductive sheet and the first contact is less than the trigger stroke between the second elastic conductive sheet and the second contact.

[0023] In one embodiment, the heat-conducting components are provided in two sets: one set of heat-conducting components connects the outer frame to the first elastic conductive sheet, and the other set of heat-conducting components connects the outer frame to the second elastic conductive sheet.

[0024] In one embodiment, the push-button switch assembly further includes:

[0025] A first mounting plate, fixed to the receiving cavity, and having a through hole, is provided on the first mounting plate; and,

[0031] This invention provides a push-button switch assembly comprising a base, an outer frame, a button body, a conductive element, a trigger part, and a heat-conducting component. The outer frame surrounds the base and together with the base forms a receiving cavity. The button body is movably mounted within the receiving cavity, with at least a portion protruding from it.

[0049] Taking a two-stage push-button switch as an example, existing electrical equipment generally uses two-stage push-button switches, but at present, two-stage push-button switches often face the problem of overheating during use.

[0050] On the one hand, the electrical contacts inside the two-stage push-button switch generate a lot of heat; on the other hand, the two-stage push-button switch has a high pressing frequency and a limited heat dissipation area, and frequent switching operations will further amplify the risk of heat accumulation.

[0051] Existing two-stage push-button switch assemblies are mainly made of traditional metal materials and have a closed structure, which prevents heat from dissipating quickly, thus shortening the switch life and increasing safety hazards.

[0052] This utility model proposes a push-button switch assembly and electrical equipment to improve the heat dissipation effect of the push-button switch assembly.

[0053] Please see Figure 1 and Figure 2 In one embodiment, the push-button switch assembly includes a base 100, an outer frame 200, a button body 300, a conductive element, a trigger portion, and a heat-conducting assembly.

[0054] The base 100 provides a mounting position for the push-button switch assembly. An outer frame 200 is provided around the periphery of the base 100, and the outer frame 200 surrounds the base 100 and together with the base 100 forms a receiving cavity. In one embodiment, the outer frame 200 is fixed to the base 100, and the outer frame 200 has an opening communicating with the receiving cavity on the side away from the base 100. In one embodiment, the outer frame 200 and the base 100 can be fixedly connected by screws, snap-fits, or other methods. In another embodiment, the base 100 has the outer frame 200 integrally formed. Here, the method of fixing the outer frame 200 to the base 100 is not limited. The material of the base 100 can be polypropylene, polycarbonate, or alloy materials, etc.; the specific material of the base 100 is not limited here.

[0055] The button body 300 is movably mounted in the receiving cavity and at least partially protrudes from the receiving cavity. In one embodiment, under the action of an external force, the button body 300 can reciprocate at the opening, and the button body 300 is confined within the receiving cavity to prevent the button body 300 from detaching from the base 100. Specifically, in one embodiment, the button body 300 includes a pressing portion 310, which protrudes from the opening to facilitate pressing the button body 300. In one embodiment, the outer frame 200 is provided with a first limiting portion 240, and the button body 300 is provided with a second limiting portion 330, which is disposed around the pressing portion 310. The second limiting portion 330 is used to abut against the first limiting portion 240 to confine the button body 300 within the receiving cavity. In one embodiment, the button body 300 can be made of polypropylene, polycarbonate, or alloy materials, etc., and the specific material of the button body 300 is not limited here.

[0056] A conductive element is disposed in the receiving cavity, and a trigger portion is disposed on the side of the button body 300 facing the base 100. The trigger portion is used to press against the conductive element. In one embodiment, the conductive element is used to electrically connect to a power line or control circuit, and the trigger portion is used to electrically connect to an electrical device. The trigger portion presses against the conductive element to control the electrical device. In one embodiment, a support rod 350 is provided on the side of the button body 300 facing the base 100, and the trigger portion is disposed on the support rod 350. The conductive element is fixed in the receiving cavity and disposed close to the base 100. When the button body 300 is pressed, the support rod 350 moves the trigger portion closer to and presses against the conductive element. When the pressing force on the button body 300 is released, the support rod 350 moves the trigger portion away from the conductive element. In one embodiment, the support rod 350 is made of insulating materials such as polypropylene, polyvinylidene fluoride, polycarbonate, or glass fiber reinforced plastic. The specific material of the support rod 350 is not limited here. The size of the support rod 350 can be flexibly set according to the trigger stroke of the trigger part and the conductive element. Here, the size of the support rod 350 is not limited.

[0057] A heat-conducting component is disposed within the receiving cavity and connects the outer frame 200 to the conductive element. Specifically, in one embodiment, one end of the heat-conducting component is connected to the conductive element via thermal conduction, and the other end of the heat-conducting component is in contact with the outer frame 200. When the button body 300 is pressed, the support rod 350 moves the trigger part closer to and presses against the conductive element, generating heat between the trigger part and the conductive element. At this time, the heat-conducting component can quickly transfer the heat to the outer frame 200. The outer frame 200 has a large surface area, which can quickly release the heat to the external environment, thereby maintaining a good tactile feel and operating temperature for the push-button switch assembly and avoiding overheating.

[0058] The technical solution of this utility model involves assembling a press switch assembly with a base 100, an outer frame 200, a button body 300, a conductive element, a trigger part, and a heat-conducting component. The outer frame 200 surrounds the base 100 and together with the base 100 forms a receiving cavity. The button body 300 is movably mounted in the receiving cavity and at least partially protrudes from it. The conductive element is located in the receiving cavity. The trigger part is located on the side of the button body 300 facing the base 100 and is used to press against the conductive element. The heat-conducting component is located in the receiving cavity and connects the outer frame 200 and the conductive element. Compared to existing press switch assemblies that cannot quickly dissipate heat, the technical solution of this utility model provides a heat-conducting component that connects the outer frame 200 and the conductive element to quickly transfer heat to the outer frame 200, preventing heat accumulation. The heat transferred to the outer frame 200 can be quickly released to the external environment, improving the heat dissipation effect of the press switch assembly.

[0059] Please see Figure 2 and Figure 3The heat-conducting component includes a first heat-conducting element 610, a second heat-conducting element 620, and a heat-conducting pad 630.

[0060] The first heat-conducting element 610 is disposed on the outer frame 200. Specifically, in one embodiment, the first heat-conducting element 610 is sheet-shaped and fits against the outer frame 200 to improve the heat dissipation efficiency of the outer frame 200. In one embodiment, the first heat-conducting element 610 is configured as a graphite sheet, which has excellent thermal conductivity and high temperature resistance, enabling rapid heat dissipation of the push-button switch assembly and ensuring safe use. Of course, in other embodiments, the material of the first heat-conducting element 610 can also be polyimide, polybutylene terephthalate, or aluminum alloy heat-conducting sheet, etc., and no specific limitation is made here. The size and shape of the first heat-conducting element 610 can be flexibly set according to actual needs, and no limitation is made here.

[0061] The second heat-conducting element 620 is disposed in the receiving cavity and connects the first heat-conducting element 610 and the conductive element. In one embodiment, one end of the second heat-conducting element 620 extends out of the receiving cavity to facilitate contact with the first heat-conducting element 610, and the other end of the second heat-conducting element 620 is connected to the conductive element by thermal conduction. Specifically, in one embodiment, the second heat-conducting element 620 has a snap-fit ​​portion 621 facing the first heat-conducting element 610, and the first heat-conducting element 610 has a notch 611. The snap-fit ​​portion 621 corresponds to the notch 611 to ensure stable contact between the first heat-conducting element 610 and the second heat-conducting element 620. In another embodiment, the first heat-conducting element 610 has a snap-fit ​​portion 621, and the second heat-conducting element 620 has a notch 611. Of course, in other embodiments, the first heat-conducting element 610 and the second heat-conducting element 620 can also directly abut against each other. Here, the contact method of the first heat-conducting element 610 and the second heat-conducting element 620 is not limited.

[0062] A thermally conductive pad 630 is disposed between the conductive element and the second thermally conductive element 620 to transfer heat from the conductive element to the second thermally conductive element 620. In one embodiment, the second thermally conductive element 620 has an extension 622 corresponding to the thermally conductive pad 630. One end of the thermally conductive pad 630 is in contact with the conductive element, and the other end of the thermally conductive pad 630 is in contact with the extension 622 to avoid direct contact between the conductive element and the second thermally conductive element 620. Specifically, in one embodiment, two thermally conductive pads 630 are provided at intervals, and the second thermally conductive element 620 is provided with two corresponding extensions 622 to improve the heat transfer speed. Of course, in other embodiments, one or more thermally conductive pads 630 may be provided, and the second thermally conductive element 620 may be provided with one or more corresponding extensions 622. The specific number of thermally conductive pads 630 is not limited here. The thermal pad 630 can be made of a material with good thermal conductivity and insulation, such as silicone, polyimide, or polytetrafluoroethylene, to prevent electrical conduction to the outer frame 200. No specific material is limited for the thermal pad 630.

[0063] Furthermore, in one embodiment, the second heat-conducting element 620 is configured as graphene foam.

[0064] In one embodiment, when the button body 300 is pressed, the conductive element presses against the trigger portion, causing the conductive element to undergo bending pressure and elastic deformation. The second heat-conducting element 620 is disposed close to the conductive element and is subjected to at least part of the bending pressure. Graphene foam not only has excellent conductivity and rigidity but also good elasticity and flexibility. Graphene foam can recover its original shape after being subjected to bending pressure, ensuring normal heat transfer. Of course, in other embodiments, the second heat-conducting element 620 can also be made of materials with high conductivity and elasticity, such as carbon fiber foam, carbon nanotube foam, or graphene-based composite materials. The specific material of the second heat-conducting element 620 is not limited here.

[0065] The technical solution of this utility model embodiment avoids heat accumulation inside the push-button switch assembly by setting a first heat-conducting element 610, a second heat-conducting element 620, and a heat-conducting pad 630 in the heat-conducting component. The heat-conducting pad 630 prevents electricity from being transferred to the outer frame 200, improving the safety of the push-button switch assembly. The second heat-conducting element 620 is configured as graphene foam, ensuring the normal operation of the push-button switch assembly and thus improving its service life. The first heat-conducting element 610 is located on the outer frame 200, concentrating heat on the outer frame 200 to allow better contact between heat and air, further improving the heat dissipation effect of the push-button switch assembly.

[0066] Please see Figure 1 and Figure 3 In one embodiment, the outer frame 200 includes a frame body 210 and an outer cover 220. The frame body 210 is provided with a connection hole 212, and one end of the second heat-conducting member 620 extends out of the connection hole 212. The outer cover 220 covers the frame body 210 and is provided with ventilation holes. The outer cover 220 and the frame body 210 together form a limiting groove 230, and the first heat-conducting member 610 is disposed in the limiting groove 230.

[0067] The frame 210 provides support for the push-button switch assembly. Specifically, in one embodiment, the frame 210 is fixed to the base 100 and together with the base 100 forms a receiving cavity. The frame 210 is provided with a connection hole 212 adapted to the size of the second heat-conducting element 620, through which the second heat-conducting element 620 can extend into the receiving cavity to contact the first heat-conducting sheet. The frame 210 can be made of high-temperature resistant and heat-dissipating materials such as polyimide, polycarbonate, reinforced fiber plastic, or alloy materials; no specific material is limited for the frame 210.

[0068] In one embodiment, the sidewall of the frame 210 has a groove, and the outer cover 220 covers the frame 210. The groove of the frame 210 and the outer cover 220 together form a limiting groove 230. The first heat-conducting element 610 is fixed in the limiting groove 230 and fits snugly against the frame 210 and the outer cover 220. In one embodiment, the outer cover 220 covers the frame 210 and is detachably connected to the frame 210. Here, the connection method between the outer cover 220 and the frame 210 is not limited. Further, in one embodiment, the outer cover 220 has a breathable mesh structure, which allows the first heat-conducting element 610 to better contact with the air and improves heat dissipation efficiency. Of course, in other embodiments, the outer cover 220 may only have multiple vent holes. Here, the number of vent holes and the specific structure of the outer cover 220 are not limited. The outer cover 220 can be made of materials that are resistant to high temperatures and have good heat dissipation, such as polyimide, polycarbonate, reinforced fiber plastic or alloy materials. There are no restrictions on the specific materials of the outer cover 220.

[0069] The technical solution of this utility model embodiment sets the outer frame 200 as a frame body 210 and an outer cover 220. The frame body 210 can protect the internal structure of the push-button switch assembly, preventing internal contamination and damage. The frame body 210 and the outer cover 220 fix the first heat-conducting element 610, which can transfer heat to the outer cover 220. The outer cover 220 is provided with vent holes, which increases the contact area between heat and air, further improving the heat dissipation effect of the push-button switch assembly.

[0070] Please see Figure 1 and Figure 2 In one embodiment, the conductive element includes a first elastic conductive sheet 410 and a second elastic conductive sheet 420, and the triggering part includes a first contact 510 and a second contact 520. The triggering stroke between the first elastic conductive sheet 410 and the first contact 510 is less than the triggering stroke between the second elastic conductive sheet 420 and the second contact 520.

[0071] In one embodiment, the conductive element is an elastic conductive sheet with good elastic deformation capability, and the trigger part is a contact corresponding to the elastic conductive sheet. The contact and the elastic conductive sheet are pressed together, causing the elastic conductive sheet to undergo elastic deformation. The elastic conductive sheet can then return to its original shape to ensure normal use. Further, in one embodiment, the push-button switch assembly is a two-stage push-button switch, with two contacts and two elastic conductive sheets. The trigger stroke between the first elastic conductive sheet 410 and the first contact 510 is defined as the first trigger stroke, and the trigger stroke between the second elastic conductive sheet 420 and the second contact 520 is defined as the second trigger stroke. The specific values ​​of the first and second trigger strokes can be flexibly set according to actual needs and are not limited here.

[0072] Specifically, in one embodiment, two support rods 350 are spaced apart on the button body 300. The two support rods 350 are of the same size, and the first contact 510 and the second contact 520 are respectively located on one support rod 350. The first elastic conductive sheet 410 and the second elastic conductive sheet 420 are spaced apart along the moving direction of the button body 300. The first elastic conductive sheet 410 is closer to the button body 300 than the second elastic conductive sheet 420 to ensure that the first trigger stroke is less than the second trigger stroke. Further, in one embodiment, after the first contact 510 presses against the first elastic conductive sheet 410, the second contact 520 and the second elastic conductive sheet 420 need to press against each other within a specified time range in order to achieve control of the electrical equipment. The specified time range can be flexibly set according to actual needs and is not limited here. In another embodiment, the two support rods 350 are of different sizes, and the distance between the first elastic conductive sheet 410 and the second elastic conductive sheet 420 and the button body 300 is the same, which can also achieve the first trigger stroke being less than the second trigger stroke. Here, the specific positions of the first elastic conductive sheet 410 and the second elastic conductive sheet 420, as well as the dimensions of the two support rods 350, are not limited. Of course, in other embodiments, only one or more elastic conductive sheets and contacts may be provided; here, the specific number of elastic conductive sheets and contacts is not limited.

[0073] Thus, when the button body 300 is pressed for the first time, since the first trigger stroke is less than the second trigger stroke, the first contact 510 first presses against the first elastic conductive sheet 410, making the push-button switch assembly active; when the button body 300 is pressed a second time with greater pressing force within a specified time range, the first elastic conductive sheet 410 deforms, and at the same time the second contact 520 presses against the second elastic conductive sheet 420, activating the circuit of the electrical equipment, realizing the control of the electrical equipment, and ensuring the safety and reliability of the push-button switch assembly.

[0074] Please see Figure 2 and Figure 3 In one embodiment, the heat-conducting components are provided in two sets: one set of heat-conducting components connects the outer frame 200 to the first elastic conductive sheet 410, and the other set of heat-conducting components connects the outer frame 200 to the second elastic conductive sheet 420.

[0075] In one embodiment, two sets of heat-conducting components are arranged opposite to each other. One set of heat-conducting components is located at the end of the first elastic conductive sheet 410 away from the second elastic conductive sheet 420, and the other set of heat-conducting components is located at the end of the second elastic conductive sheet 420 away from the first elastic conductive sheet 410. Gaps are formed between the first elastic conductive sheet 410 and the second elastic conductive sheet 420, and between the two sets of heat-conducting components, to provide deformation space for the first elastic conductive sheet 410 and to ensure that the second contact 520 can smoothly press against the second elastic conductive sheet 420, thereby ensuring the normal operation of the push-button switch assembly. Furthermore, in one embodiment, the number and position of the heat-conducting components can be flexibly set according to the number and position of the elastic conductive sheets; no specific limitations are imposed here.

[0076] In this way, the heat generated by the first elastic conductive sheet 410 and the first contact 510 pressing against each other, as well as the heat generated by the second elastic conductive sheet 420 and the second contact 520 pressing against each other, can be transferred to the outer frame 200 through the heat-conducting component, further improving the heat dissipation effect of the push-button switch assembly.

[0077] Please see Figure 2 and Figure 3 In one embodiment, the push-button switch assembly further includes a first mounting plate 710 and a second mounting plate 720. The first mounting plate 710 is fixed to the receiving cavity and has a through hole 711, and a first elastic conductive sheet 410 is disposed on the first mounting plate 710; the second mounting plate 720 is fixed to the receiving cavity, and a second elastic conductive sheet 420 is disposed on the second mounting plate 720 and corresponds to the through hole 711.

[0078] The first mounting plate 710 provides a mounting base 100 and support for the first elastic conductive sheet 410, and the second mounting plate 720 provides a mounting base 100 and support for the second elastic conductive sheet 420. Specifically, in one embodiment, the first mounting plate 710 and the second mounting plate 720 are fixed to the frame 210 at a distance, and the first mounting plate 710 has a through hole 711 at the position corresponding to the second elastic conductive sheet 420 for the second contact 520 to pass through. Further, in one embodiment, two sets of heat-conducting components are located between the first mounting plate 710 and the second mounting plate 720, and the two second heat-conducting elements 620 of the two sets of heat-conducting components are respectively partially attached to the first mounting plate 710 and the second mounting plate 720. In one embodiment, a first support member 730 is provided between the first mounting plate 710 and a set of heat-conducting components, and the first support member 730 is located between a set of heat-conducting pads 630 and the frame 210. A second support member 740 is provided between the second mounting plate 720 and another set of heat-conducting components. The second support member 740 is located between the other set of heat-conducting pads 630 and the frame 210, that is, the first support member 730 and the second support member 740 are located at opposite ends of the first mounting plate 710. Further, in one embodiment, the base 100 is mounted on electrical equipment, and a heat insulation member 640 is provided between the second mounting plate 720 and the base 100 to prevent heat from the second elastic conductive sheet 420 from being transferred to the base 100 and then to the electrical equipment. The heat insulation member 640 can be configured as an insulating material with heat insulation properties such as polyvinyl chloride, polyurethane foam, or rubber, and no specific limitation is made here. The first mounting plate 710 can be made of an elastic insulating material such as rubber, silicone, polyurethane, or polyethylene, and the second mounting plate 720 can be made of an insulating material such as polyvinyl chloride, polypropylene, or polyester resin. No specific limitation is made here on the specific materials of the first mounting plate 710 and the second mounting plate 720. The first support member 730 and the second support member 740 can be made of materials with good strength such as polypropylene, polyethylene terephthalate or polyurethane resin. Here, no restrictions are placed on the specific materials of the first support member 730 and the second support member 740.

[0079] The technical solution of this embodiment of the utility model provides support and positioning for the conductive elements and heat-conducting components by setting a first mounting plate 710 and a second mounting plate 720. Two sets of heat-conducting components are located between the first mounting plate 710 and the second mounting plate 720, preventing heat accumulation on the base 100 and ensuring effective heat dissipation. The first mounting plate 710 is made of an elastic insulating material to facilitate elastic deformation of the first elastic conductive sheet 410, while also preventing electrical transfer to the frame 210, thus improving the safety of the push-button switch assembly. The first support member 730 and the second support member 740 provide support for the first mounting plate 710 and provide deformation space for the first mounting plate 710, ensuring the normal operation of the push-button switch assembly.

[0080] Please see Figure 2 and Figure 3 In one embodiment, the push-button switch assembly further includes an elastic element 800 disposed between the button body 300 and the first mounting plate 710, the elastic element 800 causing the button body 300 to tend to move away from the first mounting plate 710.

[0081] Specifically, in one embodiment, two elastic elements 800 are provided, spaced apart at opposite ends of the button body 300. Of course, in other embodiments, one or more elastic elements 800 may be provided; the specific number is not limited here. In one embodiment, the button body 300 is provided with a first mounting block 340, and a second mounting block 712 is provided on a first mounting plate 710. One end of the elastic element 800 is fitted onto the first mounting block 340, and the other end of the elastic element 800 is fitted onto the second mounting block 712. Of course, in other embodiments, the elastic element 800 can also be connected to the button body 300 and the first mounting plate 710 by means of adhesion, snap-fit, or abutment; the arrangement of the elastic element 800 is not limited here. The elastic element 800 can be a spring, a rubber elastomer, or silicone rubber, etc., and is not limited here.

[0082] Thus, when the button body 300 is pressed, the button body 300 moves toward the first mounting plate 710 to compress the elastic member 800, causing the trigger part to press against the conductive element. When the pressing force on the button body 300 is released, under the elastic force of the elastic member 800, the button body 300 tends to move away from the first mounting plate 710, and the trigger part and the conductive element separate.

[0083] Please see Figure 2 and Figure 3 In one embodiment, the button body 300 is provided with a protrusion 320, and the outer frame 200 is provided with a slide groove 211, with the protrusion 320 and the slide groove 211 corresponding to each other.

[0084] In one embodiment, the side wall of the frame 210 is provided with two opposing grooves 211, and the button body 300 is provided with two opposing protrusions 320, each corresponding to a groove 211. The protrusions 320 engage with the grooves 211, allowing the button body 300 to move along the grooves 211 towards the conductive element, so that the trigger portion presses against the conductive element. Of course, in other embodiments, one or more protrusions 320 may be provided, and one or more corresponding grooves 211 may be provided; the number of protrusions 320 and grooves 211 is not limited. The size of the grooves 211 can be flexibly set according to the trigger stroke; the size of the grooves 211 is not limited here.

[0085] The technical solution of this utility model embodiment provides a sliding groove 211 and a protrusion 320. The sliding groove 211 guides the movement of the button body 300 toward the conductive element. The protrusion 320 engages with the sliding groove 211, which limits the button body 300, prevents the button body 300 from rotating, ensures precise correspondence between the trigger part and the conductive element, and thus ensures the normal use of the button switch body.
