[0027] The sealing ring has an annular protrusion at its end facing the upper cover, and the annular protrusion matches the shape of the sealing groove.

[0028] According to a third aspect of this utility model, a power supply detection device is also provided, the power supply detection device comprising:

[0029] The protective device as described in any of the above utility model contents;

[0030] A power detection module is located within the accommodating cavity and is positioned in a limiting fit with the housing assembly.

[0031] In one optional utility model, a limiting groove is provided along the axial direction at the first end of the switch button.

Detailed Implementation

[0051] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0052] Currently, switch assemblies typically include a reset spring and a button. The reset spring is mounted along the axial direction of the button, so that when the reset spring is pressed, the button presses down against the switch contacts to make the circuit conduction. When the pressure on the button is released, the reset spring drives the button to reset.

[0053] However, when the button is pressed down, a large switching gap is formed between the button and the outer housing, resulting in poor protection of the switch assembly.

[0054] Based on the aforementioned technical problems, this utility model is proposed. This utility model may include a switch button, a resilient arm, and a sealing ring. When the switch button is pressed, it triggers a control switch. The resilient arm is arranged radially along the switch button. The resilient arm is in a limiting fit with the housing assembly. The resilient arm undergoes elastic deformation when the switch button is pressed and resets the switch button through elastic restoring force. The sealing ring is fitted onto the outer periphery of the switch button to seal the assembly gap between the switch button and the housing assembly. Therefore, when the user presses the switch button to trigger the control switch, the resilient arm deforms axially with the switch button, and the sealing ring ensures the sealing of the assembly gap between the switch button and the housing assembly, improving the dustproof and waterproof effect of the switch assembly. Furthermore, using a resilient arm distributed radially along the switch button, compared to a helically distributed return spring, can significantly reduce the structural material required for the switch button's reset function, thus reducing the structural cost of the switch assembly.

[0055] Reference Figure 1-3As shown, this embodiment of the present invention provides a switch assembly 100, which may include a switch button 110, an elastic arm 120, and a sealing ring 130. When the switch button 110 is pressed, it contacts a control switch 310. The elastic arm 120 is arranged radially along the switch button 110. The elastic arm 120 is in a limiting fit with the housing assembly 200. The elastic arm 120 undergoes elastic deformation when the switch button 110 is pressed and resets the switch button 110 through elastic restoring force. The sealing ring 130 is fitted onto the outer periphery of the switch button 110 to seal the assembly gap between the switch button 110 and the housing assembly 200.

[0056] In this embodiment of the invention, the switch assembly 100 may include a switch button 110, a resilient arm 120, and a sealing ring 130. The switch button 110 is used by a user to press and operate the control switch 310. For example, when the switch button 110 is pressed, it abuts against the control switch 310, thereby turning the control circuit of the control switch 310 on or off. The position of the switch button 110 is limited by the limiting cooperation between the resilient arm 120 and the housing assembly 200. The switch button 110 may be a cylindrical structure.

[0057] The elastic arm 120 is positioned near the first end of the switch button 110 and radially along the switch button 110. The elastic arm 120 engages with the housing assembly 200 to limit its position. When the switch button 110 is pressed, the elastic arm 120 adapts to the axial displacement of the switch button 110, generating elastic deformation along the axial direction. When the switch button 110 is released, the elastic arm 120, due to its elastic restoring force, drives the switch button 110 to reset axially. Therefore, compared to a helically distributed return spring, the structural material required for the reset of the switch button 110 can be significantly reduced. For example, a spring made of metal can be replaced with another material. This helps to reduce the structural cost of the switch assembly 100.

[0058] The sealing ring 130 is fitted onto the outer periphery of the switch button 110 to seal the assembly gap between the switch button 110 and the housing assembly 200. For example, the sealing ring 130 is interference-fitted with the switch button 110, and during assembly of the switch button 110 and the housing assembly 200, a sealing connection at the assembly gap is achieved through a compression fit between the housing assembly 200 and the sealing ring 130. When the switch button 110 is pressed, the sealing ring 130 maintains the seal between the switch button 110 and the housing assembly 200, thereby maintaining the sealing performance of the assembly of the switch assembly 100 and the housing assembly 200, greatly improving the protective effect of the switch assembly 100, such as improving its dustproof and waterproof performance.

[0059] An optional utility model embodiment, referring to... Figure 1 and Figure 2 As shown, the elastic arm 120 may include an arcuate portion 121 and a bent rib portion 122. The arcuate portion 121 is distributed along the radial circumference of the switch button 110. The bent rib portion 122 extends outward along the radial end face of the arcuate portion 121 away from the switch button 110. The bent rib portion 122 is provided with a first limiting feature 1221 that cooperates with the housing assembly 200 for limiting. The bent rib portion 122 undergoes elastic deformation when the switch button 110 is pressed.

[0060] In this embodiment of the invention, the elastic arm 120 may include an arcuate portion 121 and a bent rib portion 122, wherein the arcuate portion 121 is distributed along the radial circumference of the switch button 110. The connection between the arcuate portion 121 and the switch button 110 improves the structural connection strength between the elastic arm 120 and the switch button 110, thereby increasing the service life of the elastic arm 120.

[0061] The bent rib 122 extends outward along the radial end face of the arc portion 121 away from the switch button 110. The bent rib 122 is provided with a first limiting feature 1221 that engages with the housing assembly 200. For example, one end of the bent rib 122 is connected to the arc portion 121, and the other end of the bent rib 122 is provided with the first limiting feature 1221. By forming a limiting engagement with the housing assembly 200 through the first limiting feature 1221, the position of the elastic arm 120 and the switch button 110 can be limited. The bent rib 122 adapts to deformation due to its relatively thin thickness, and it has a bending region. Therefore, when the arc portion 121 moves the bent rib 122, the axial displacement is converted into elastic deformation through the torsion of the bending region.

[0062] When the switch button 110 is pressed, the arcuate portion 121 moves axially along with the switch button 110, and the middle area of ​​the bent rib portion 122 undergoes elastic deformation along with the arcuate portion 121. When the pressure of the switch button 110 is released, the bent rib portion 122 elastically recovers and drives the arcuate portion 121 connected to it to move axially, and the arcuate portion 121 drives the switch button 110 connected to it to move synchronously and reset.

[0063] Based on the above structural design, while simplifying the structure of the elastic arm 120, the connection between the elastic arm 120 and the switch button 110 can be strengthened, and the service life of the elastic arm 120 can be increased.

[0064] In one example, the first limiting feature 1221 can be a groove or a protrusion, cooperating with the second limiting feature 230 provided on the housing assembly 200. For example, the second limiting feature 230 can be a protrusion or a groove. The first limiting feature 1221 and the second limiting feature 230 form a limiting fit through snap-fit ​​or interference fit. If a snap-fit ​​method is used, the protrusion can be shaped, for example, a portion of the protrusion can be a conical structure, thereby achieving a firm snap-fit ​​between the first limiting feature 1221 and the second limiting feature 230. The conical structure design prevents the first limiting feature 1221 and the second limiting feature 230 from falling off.

[0065] An optional utility model embodiment, referring to... Figure 1 and Figure 6 As shown, the side of the switch button 110 is provided with a first positioning step 111, and the inner side of the sealing ring 130 is provided with a second positioning step 131. The first positioning step 111 and the second positioning step 131 are shaped to fit together to define the axial fitting position of the sealing ring 130 on the switch button 110.

[0066] In this embodiment of the invention, the first positioning step 111 may be provided on the radial side of the switch button 110. For example, the first positioning step 111 may be a two-step shape. Furthermore, the diameter of the switch button 110 gradually increases from the direction near the elastic arm 120 to the direction away from the elastic arm 120.

[0067] The second positioning step 131 is shaped to match the first positioning step 111. In other words, the diameter of the inner opening of the sealing ring 130 gradually increases from the direction near the elastic arm 120 to the direction away from the elastic arm 120. During assembly, the sealing ring 130 can be fitted from the first end of the switch button 110 onto the first positioning step 111 of the switch button 110. Thus, the axial fitting position of the sealing ring 130 can be limited by the cooperation between the first positioning step 111 and the second positioning step 131.

[0068] Based on the above structural design, the sealing ring 130 can be accurately positioned in the axial fitting position of the switch button 110, and the assembly sealing between the switch assembly 100 and the housing assembly 200 can be improved.

[0069] In one optional embodiment of the utility model, the arcuate portion 121 and the bent rib portion 122 are integrally formed. And / or, the switch button 110 and the elastic arm 120 are integrally formed.

[0070] In this embodiment of the present invention, the integrated design of the arc portion 121 and the bending rib portion 122 can improve the structural connection strength between the arc portion 121 and the bending rib portion 122, thereby avoiding the connection breakage between the arc portion 121 and the bending rib portion 122 during repeated deformation of the elastic arm 120, and further improving the structural strength and service life of the elastic arm 120.

[0071] The integrated design of the switch button 110 and the elastic arm 120 improves the structural connection strength between them, further enhancing the structural strength and service life of the switch assembly 100. Both the elastic arm 120 and the switch button 110 can be injection molded.

[0072] Based on the above structural design, the structural connection strength between the elastic arm 120 and / or the switch button 110 and the elastic arm 120 can be improved, thereby improving the overall structural strength and service life of the switch assembly 100.

[0073] In summary, this utility model discloses a switch assembly 100, which may include a switch button 110, an elastic arm 120, and a sealing ring 130. When the switch button 110 is pressed, it triggers a control switch 310. The elastic arm 120 is arranged radially along the switch button 110. The elastic arm 120 is in a limiting fit with the housing assembly 200. The elastic arm 120 undergoes elastic deformation when the switch button 110 is pressed and resets the switch button 110 through elastic restoring force. The sealing ring 130 is fitted onto the outer periphery of the switch button 110 to seal the assembly gap between the switch button 110 and the housing assembly 200. Thus, when the user presses the switch button 110 to trigger the control switch 310, the elastic arm 120 deforms axially with the switch button 110, and the sealing ring 130 ensures the sealing of the assembly gap between the switch button 110 and the housing assembly 200, improving the dustproof and waterproof effect of the switch assembly 100. Furthermore, by employing elastic arms 120 radially distributed along the switch button 110, compared to a helically distributed return spring, the structural material required for the reset of the switch button 110 can be significantly reduced, which is beneficial for reducing the structural cost of the switch assembly 100.

[0074] Reference Figure 4 As shown in the figure, this utility model embodiment also discloses a protective device, which may include a housing assembly 200 and a switch assembly 100 as described in any of the above utility model embodiments. The housing assembly 200 includes a receiving cavity 201 and a button channel 202, the button channel 202 communicating with the receiving cavity 201. The switch assembly 100 is located within the receiving cavity 201, and the switch button 110 is embedded in the button channel 202. The elastic arm 120 forms a limiting engagement with the housing assembly 200.

[0075] In this embodiment of the present invention, the housing assembly 200 has a receiving cavity 201 and a button channel 202. The receiving cavity 201 provides a sealed mounting space for the switch assembly 100, and the button channel 202 provides a pressing channel for the user to press the switch button 110. The button channel 202 communicates with the receiving cavity 201. Therefore, when the switch assembly 100 is assembled inside the receiving cavity 201, the switch button 110 can be embedded (or recessed) in the button channel 202. Thus, the user can press the exposed switch button 110 based on the button channel 202, thereby contacting the control switch 310 located in the switch assembly 100.

[0076] The elastic arm 120 is positioned near the first end of the switch button 110 and radially along the switch button 110. The elastic arm 120 engages with the housing assembly 200 to limit its position. When the switch button 110 is pressed, the elastic arm 120 adapts to the axial displacement of the switch button 110, generating elastic deformation along the axial direction. When the switch button 110 is released, the elastic arm 120, due to its elastic restoring force, drives the switch button 110 to reset axially. Therefore, compared to a helically distributed return spring, the structural material required for the reset of the switch button 110 can be significantly reduced. For example, a spring made of metal can be replaced with another material. This helps to reduce the structural cost of the switch assembly 100.

[0077] The sealing ring 130 is fitted onto the outer periphery of the switch button 110 and located inside the housing assembly 200, serving to seal the assembly gap between the switch button 110 and the housing assembly 200. When the switch button 110 is pressed, the sealing ring 130 maintains the seal between the switch button 110 and the housing assembly 200, thereby ensuring the airtight assembly of the switch assembly 100 and the housing assembly 200, significantly improving the protective effect of the switch assembly 100, such as enhancing its dustproof and waterproof performance.

[0078] An optional utility model embodiment, referring to... Figure 4 As shown, the housing assembly 200 may include a top cover 210 and a base 220. The top cover 210 has a button channel 202. The base 220 is detachably connected to the top cover 210, and their shapes fit together to form the receiving cavity 201. The detachable connection may include, but is not limited to, threaded connections or snap-fit ​​connections. For example, the top cover 210 has a buckle or a slot, and the base 220 has a corresponding slot or buckle. By assembling the top cover 210 onto the base 220, the buckle and slot fit together, completing the assembly of the top cover 210 and the base 220. Based on the above structural design, the ease of assembling and disassembling the switch assembly 100 in the housing assembly 200 can be improved.

[0079] An optional utility model embodiment, referring to... Figure 7 As shown, the housing assembly 200 may further include a second limiting feature 230, which is located on the upper cover 210 and engages with the first limiting feature 1221 provided on the elastic arm 120.

[0080] In this embodiment of the present invention, the first limiting feature 1221 can be a groove or a protrusion, which cooperates with the second limiting feature 230 provided on the upper cover 210. For example, the second limiting feature 230 can be a protrusion or a groove. The first limiting feature 1221 and the second limiting feature 230 are engaged by snap-fit ​​or interference fit. If a snap-fit ​​method is used, the protrusion can be shaped, for example, a portion of the protrusion can be a conical structure, thereby achieving a firm snap-fit ​​between the first limiting feature 1221 and the second limiting feature 230. The conical structure design prevents the first limiting feature 1221 and the second limiting feature 230 from falling off.

[0081] When assembling the housing assembly 200 and the switch assembly 100, the sealing ring 130 can be first fitted onto the switch button 110, and then the second limiting feature 230 on the upper cover 210 can be assembled with the first limiting feature 1221 on the elastic arm 120, thus completing the assembly of the switch assembly 100 and the upper cover 210. Based on the above structural design, the assembly efficiency of the switch assembly 100 and the housing assembly 200 can be improved.

[0082] An optional utility model embodiment, referring to... Figure 4 As shown, the sidewalls of the button channel 202 are arranged in a stepped manner, wherein the diameter of the button channel 202 gradually increases from the direction closer to the switch button 110 to the direction farther away from the switch button 110.

[0083] In this embodiment of the invention, the diameter of the button channel 202 gradually increases from the direction closer to the switch button 110 to the direction farther away from the switch button 110. This can be understood as the diameter of the button channel 202 gradually increasing axially towards the outer side of the housing assembly 200. Therefore, the gap between the button channel 202 and the switch button 110 is larger in the area closer to the outer side. This provides more space for the user to press, avoiding a poor pressing experience due to the small area of ​​the switch button 110.

[0084] On the other hand, the stepped distribution of the channel sidewalls allows the spatial depth between the switch button 110 and the button channel 202 to gradually decrease radially outwards, preventing external impurities from accumulating in the deepest area and making cleaning difficult. Furthermore, it improves the aesthetic appeal of the channel sidewalls of the button channel 202, thereby enhancing the user experience.

[0085] An optional utility model embodiment, referring to... Figure 6As shown, a sealing groove 2101 is formed on the end face of the upper cover 210 near the base 220, and the sealing groove 2101 surrounds the button channel 202. In other words, the sealing groove 2101 is an annular groove, and the sealing ring 130 has an annular protrusion 132 at its end facing the upper cover 210. The annular protrusion 132 can be integrally formed with the sealing ring 130, and its shape matches the sealing groove 2101. When the switch button 110 and the upper cover 210 are assembled, the sealing ring 130 and the upper cover 210 are pressed together, and the annular protrusion 132 is pressed together with the sealing groove 2101, thereby forming a sealed connection.

[0086] By having the annular protrusion 132 extending into the interior of the upper cover 210 engage with the sealing groove 2101 of the upper cover 210, the sealing performance between the upper cover 210 and the switch button 110 can be further improved. Furthermore, when the sealing ring 130 undergoes axial displacement away from the upper cover 210 due to the pressing of the switch button 110, the annular protrusion 132 located in the sealing groove 2101 can offset part of the displacement tension of the sealing ring 130 caused by the switch button 110. This allows the sealing ring 130 to deform to accommodate the axial displacement of the switch button 110, thus maintaining a seal at the assembly gap between the switch button 110 and the upper cover 210.

[0087] In summary, this utility model discloses a protective device, which may include a switch button 110, an elastic arm 120, and a sealing ring 130. When the switch button 110 is pressed, it contacts the control switch 310. The elastic arm 120 is arranged radially along the switch button 110. The elastic arm 120 is in a limiting fit with the housing assembly 200. The elastic arm 120 undergoes elastic deformation when the switch button 110 is pressed and resets the switch button 110 through elastic restoring force. The sealing ring 130 is fitted onto the outer periphery of the switch button 110 to seal the assembly gap between the switch button 110 and the housing assembly 200. Thus, when the user presses the switch button 110 to contact the control switch 310, the elastic arm 120 deforms axially with the switch button 110, and the sealing ring 130 ensures the sealing of the assembly gap between the switch button 110 and the housing assembly 200, improving the dustproof and waterproof effect of the switch assembly 100. Furthermore, by employing elastic arms 120 radially distributed along the switch button 110, compared to a helically distributed return spring, the structural material required for the reset of the switch button 110 can be significantly reduced, which is beneficial for reducing the structural cost of the switch assembly 100.

[0088] Reference Figure 5-9 As shown in the figure, this utility model embodiment also discloses a power supply detection device, which may include a power supply detection module 300 and a protective device as described in any of the above utility model embodiments. The power supply detection module 300 is located within the accommodating cavity 201 and is limitedly fitted with the housing assembly 200.

[0089] In this embodiment of the invention, the power detection device may be a device with a switch for detecting power supply. For example, the power detection device may be an air conditioner companion device used to detect whether the mains power connected to the air conditioner is interrupted. The power detection module 300 is assembled inside the accommodating cavity 201 and is positioned and engaged with the housing assembly 200, thereby enabling the positioning and assembly of the power detection module 300 through the structural design of the housing assembly 200.

[0090] An optional utility model embodiment, referring to... Figure 5 and Figure 9 As shown, a limiting groove 1101 is provided axially at the first end of the switch button 110. The limiting groove 1101 is used to mate with the shape of the control switch 310 integrated on the power detection module 300 to form a limiting engagement between the switch button 110 and the control switch 310. The axial depth of the limiting groove 1101 is greater than the axial travel of the switch button 110.

[0091] Based on the above structural design, the assembly accuracy between the switch button 110 and the control switch 310 can be improved, and it can be ensured that the switch button 110 can form a limiting engagement with the control switch 310 whether it is pressed or not, so as to avoid positional displacement between the switch button 110 and the control switch 310, which would affect the control accuracy of the power detection module 300.

[0092] An optional utility model embodiment, referring to... Figure 5 , Figure 8 as well as Figure 9As shown, the housing assembly 200 includes a top cover 210 and a base 220. The top cover 210 and the base 220 cooperate to form the receiving cavity 201. The housing assembly 200 may also include a first limiting member 240, a second limiting member 250, and a third limiting member 260. The first limiting member 240 is disposed on the base 220 to support the power detection module 300. The second limiting member 250 is disposed on the top cover 210 and cooperates with the first limiting member 240 to limit the power detection module 300 axially along the switch button 110. The third limiting member 260 is disposed on the base 220, and the power detection module 300 has an assembly groove 3001. The third limiting member 260 is shaped to fit the assembly groove 3001 to limit the power detection module 300 radially along the switch button 110.

[0093] In this embodiment of the present invention, the housing assembly 200 may include a top cover 210 and a base 220. The top cover 210 has a button channel 202, and the base 220 is detachably connected to the top cover 210, and their shapes are matched to form the receiving cavity 201. The detachable connection may include, but is not limited to, threaded connections or snap-fit ​​connections. For example, the top cover 210 is provided with a buckle or a slot, and the base 220 is correspondingly provided with a slot or a buckle. By assembling the top cover 210 onto the base 220, the buckle and slot shape match, completing the assembly of the top cover 210 and the base 220. Based on the above structural design, the ease of assembly and disassembly of the switch assembly 100 in the housing assembly 200 can be improved.

[0094] The first limiting member 240 is located on the end face of the base 220 near the upper cover 210 (also referred to as the inner side of the base 220) to support the power detection module 300. For example, at least three first limiting members 240 can be provided on the upper cover 210, so that at least three first limiting members 240 can jointly form the assembly plane of the power detection module 300, thereby limiting the bottom of the power detection module 300 along the axial direction of the switch button 110.

[0095] The second limiting member 250 is located on the end face of the upper cover 210 near the base 220 (also referred to as the inner side of the upper cover 210), and is used to abut against the top of the power detection module 300, thereby limiting the top of the power detection module 300 along the axial direction of the switch button 110. For example, the second limiting member 250 can be an integral structure with the upper cover 210.

[0096] The third limiting member 260 is disposed on the inner side of the base 220 to position the power detection module 300. The first limiting member 240 and the third limiting member 260 are integrally formed with the base 220. The power detection module 300 has an assembly groove 3001, and the third limiting member 260 is shaped to fit the assembly groove 3001, thus radially limiting the power detection module 300 along the switch button 110. In other words, the third limiting member 260 restricts the movement of the power detection module 300 on the horizontal plane. Therefore, during the assembly of the power detection module 300, the assembly slot 3001 of the power detection module 300 can be made to fit the shape of the third limiting member 260, and then the power detection module 300 can be moved downward to be assembled on the first limiting member 240. Finally, the upper cover 210 is assembled. When the upper cover 210 and the base 220 are assembled, the second limiting member 250 is determined to abut against the power detection module 300.

[0097] Based on the above structural design, the positioning accuracy of the power detection module 300 can be improved by combining the first limiting member 240, the second limiting member 250 and the third limiting member 260 while ensuring ease of assembly.

[0098] In summary, this utility model discloses a power detection device, which may include a switch button 110, an elastic arm 120, and a sealing ring 130. When the switch button 110 is pressed, it contacts the control switch 310. The elastic arm 120 is arranged radially along the switch button 110. The elastic arm 120 is in a limiting fit with the housing assembly 200. The elastic arm 120 undergoes elastic deformation when the switch button 110 is pressed and resets the switch button 110 through elastic restoring force. The sealing ring 130 is fitted onto the outer periphery of the switch button 110 to seal the assembly gap between the switch button 110 and the housing assembly 200. Thus, when the user presses the switch button 110 to contact the control switch 310, the elastic arm 120 deforms axially with the switch button 110, and the sealing ring 130 ensures the sealing of the assembly gap between the switch button 110 and the housing assembly 200, improving the dustproof and waterproof effect of the switch assembly 100. Furthermore, by employing elastic arms 120 radially distributed along the switch button 110, compared to a helically distributed return spring, the structural material required for the reset of the switch button 110 can be significantly reduced, which is beneficial for reducing the structural cost of the switch assembly 100.
