Description

Technical Field

[0001] The utility model relates to the technical field of electrical circuit switch control equipment, in particular to a reset switch assembly. Background Art

[0002] A switch device is a very common circuit control device, which is widely used in people's daily lives. Usually, the switch device is placed on the wall and is mostly used to control the circuit connection and opening of electrical equipment such as lamps and air conditioners, so as to control the start and stop of the corresponding electrical equipment.

[0003] In recent years, with the improvement of living standards, users have correspondingly improved their requirements for the operation and aesthetics of switch devices. When a traditional switch device is installed on the wall together with a socket, the button panel of the switch device cannot be on the same plane as the operation panel of the socket, resulting in an uncoordinated layout of the switch device and the socket, affecting the overall aesthetic effect of the structural layout of the components on the wall.

[0004] Accordingly, the existing reset switch can meet the requirement that the outer wall of the reset switch is on the same plane when installed with the socket based on the cooperation of its reset mechanism. However, some existing reset switches need to be designed with a smaller case size because their own buttons need to trigger the bottom guide mechanism, which results in a smaller effective operating area of ​​the buttons of such reset switches, causing inconvenience to the user; although other reset switches are equipped with large-sized buttons as trigger mechanisms, in actual operation, if the user touches the edge of the button, it is difficult to trigger the button, which increases the difficulty of the user's triggering operation of the reset switch and affects the convenience and efficiency of the reset switch.

[0005] In view of this, how to optimize the component structure of the reset switch to make its button trigger more sensitive and its operation more convenient and efficient is an important technical problem that technical personnel in this field currently need to solve. Utility Model Content

Therefore, when the user presses the key panel, if the pressing contact part is in the middle of the key panel, the inner end of the transmission flap and the trigger hinge shaft will be driven to press down synchronously with the key panel until they contact and press down the trigger end of the reset function part module to trigger the reset function part module, thereby driving the circuit switch mechanism through the reset function part module to turn on or off the circuit; if the user's pressing contact part is at the end, edge or other non-central area of the key panel, the transmission flap receives the downward pressure transmitted from the key panel, so that the inner end of the transmission flap presses down synchronously with the key panel, and the inner end of the transmission flap is used to drive the trigger hinge shaft to press down synchronously until it contacts and presses down the trigger end of the reset function part module to trigger the reset function part module, thereby driving the circuit switch mechanism through the reset function part module to turn on or off the corresponding circuit.

[0045] Please refer to Figures 1 to 8 .

[0046] In the specific embodiment, the reset switch assembly provided by the present utility model includes a fixing bracket 40, a positioning panel 20 and a key panel 30 which are arranged in sequence from bottom to top and are parallel to each other. The key panel 30 can reciprocate in a direction perpendicular to its own main extension plane. A reset function part module 50 capable of controlling the on-off of a switch circuit is arranged on one side of the middle part of the positioning panel 20 facing the key panel 30, and the triggering end of the reset function part module 50 is linked with the key panel 30.

[0047] Correspondingly, a transmission mechanism linked between the key panel 30 and the reset function part module 50 is arranged between the positioning panel 20 and the key panel 30. The transmission mechanism includes a triggering hinge shaft 10 and two transmission flap plates 11 symmetrically arranged along the main extension plane of the key panel 30. The triggering hinge shaft 10 is in alignment and cooperation with the middle part of the key panel 30 and is linked with the triggering end of the reset function part module 50.

[0048] On this basis, the inner ends of the two transmission flap plates 11 are coaxially hinged to the triggering hinge shaft 10, and the outer ends of the two transmission flap plates 11 are respectively fixedly hinged to a set of opposite sides of the positioning panel 20. The rotation axis of the outer end part of the transmission flap plate 11 is parallel to the axis of the triggering hinge shaft 10.

[0049] During its operation and use, the two driving flap plates 11 cooperate with each other to form an inner turning action mechanism that is hinged in the middle and synchronously linked with the key panel 30, and the outer ends thereof rotate around fixed axes. Thus, when the user presses the key panel 30, if the pressed contact part is in the middle of the key panel 30, the inner ends of the driving flap plates 11 and the trigger hinge shaft 10 will be driven and pressed down together with the key panel 30 until they contact the trigger end of the reset function part module 50 and press down the trigger end to trigger the reset function part module 50. Thereby, the circuit switch mechanism is driven by the reset function part module 50 to turn on or off the circuit.

[0050] If the pressed contact part of the user is at the end, edge or other non-central area of the key panel 30, the driving flap plates 11 will receive the downward pressure transmitted from the key panel 30, so that the inner ends of the driving flap plates 11 will be pressed down synchronously with the key panel 30, and thereby the inner ends of the driving flap plates 11 are used to drive the trigger hinge shaft 10 to be pressed down synchronously until they contact the trigger end of the reset function part module 50 and press it down, thereby triggering the reset function part module 50, and thus the circuit switch mechanism is driven by the reset function part module 50 to turn on or off the corresponding circuit.

[0051] It should be particularly noted that when the pressed contact part of the user is at the end, edge or other non-central area of the key panel 30, due to the double-end rotation structure in which the outer ends of the driving flap plates 11 are hinged around fixed axes and the inner ends are linked and hinged with the trigger hinge shaft 10, the small pressing stroke formed at the position where the user applies the force is transmitted to the inner ends of the driving flap plates 11 based on the fixed-axis rotation of the outer ends of the driving flap plates 11 to form a large swing of the inner ends of the driving flap plates 11, thereby driving the trigger hinge shaft 10 to be pressed down synchronously by a large amount. Thus, the small pressing operation stroke of the user at the key panel 30 forms a larger pressing stroke amplitude when transmitted to the trigger hinge shaft 10, and thereby a large pressing down and triggering action on the reset function part module 50 is achieved, ensuring the overall triggering operation effect of the reset switch assembly. Considering the adapted positions and component sizes of the key panel 30 and the driving flap plates 11 and other cooperating components under normal working conditions, if the part where the user applies the pressing force on the key panel 30 is at the midpoint position of a single driving flap plate 11, the pressing force applied will form a downward stroke about twice the pressing stroke at the position where the user applies the force when transmitted to the inner end of the driving flap plate 11, thereby effectively ensuring the accurate and reliable triggering of the reset function part module 50 and ensuring the operation accuracy and use convenience of the reset switch assembly.

[0052] The reset switch assembly is arranged as a transmission trigger assembly linked between the key panel 30 and the reset function module 50 through the transmission mechanism. No matter where the user presses on the key panel 30, the action of the reset function module 50 can be effectively triggered, and the on / off control of the corresponding circuit can be realized, thereby controlling the turning on or off of the corresponding lamp or electrical appliance. As a result, the operation efficiency of the reset switch assembly is significantly improved, its key triggering is more sensitive and accurate, and the operation effect of the reset switch assembly is correspondingly optimized, making its operation more convenient and reliable.

[0053] Generally, in the middle of the top surface of the positioning panel 20, an installation groove 21 for embedding the reset function module 50 is correspondingly arranged to reliably fix the reset function module 50 in place and provide reliable structural support for the reset function module 50.

[0054] In fact, the reset function module 50 is a very common functional module in the existing reset switch assembly structure. It generally realizes the on / off control of the corresponding switch circuit through a trigger end mechanism with a pressed trigger and a rebound reset. Specifically in this solution, the specific structure and functional effect of the reset function module 50 can be directly referred to and understood according to the prior art, and will not be elaborated here.

[0055] In addition, it is not difficult to understand that the fixing bracket 40, as the main basic component of the reset switch assembly, is generally installed at the switch box on the wall as the installation base and support positioning structure for other components such as the positioning panel 20. Correspondingly, if the reset switch assembly is installed on the wall, the main body structure of the reset switch assembly is basically embedded inside the wall, and only a part of the key panel 30 and the positioning panel 20 protrude from the outer wall of the wall to form a regular arrangement structure with the adjacent socket or other switch devices. It should be noted that if it is installed on the wall, the reciprocating movement direction of the key panel 30 in this solution is the direction perpendicular to the outer wall of the wall, and the arrangement directions of the fixing bracket 40, the positioning panel 20, and the key panel 30 are also adjusted from bottom to top as described above to from inside to outside based on the main structure of the wall. In practical applications, the specific arrangement position and corresponding orientation reference of the reset switch assembly can be flexibly selected and adjusted according to the actual working conditions and understood accordingly. In principle, as long as it can meet the actual application needs of the reset switch assembly, it is acceptable.

[0056] Specifically, the transmission mechanism also includes a linkage torsion bar 12 which is linked to the two transmission flaps 11. The linkage torsion bar 12 includes a rotating shaft section 121 which is rotatably arranged on the positioning panel 20, a linkage section 122 which is linked to the two transmission flaps 11 one by one, and a torsion section 123 which is connected between the linkage section 122 and the rotating shaft section 121. The rotation axis of the rotating shaft section 121 is perpendicular to the axis of the trigger hinge shaft 10. The linkage section 122 is arranged one by one at the two ends of the rotating shaft section 121 through the torsion section 123.

[0057] During actual operation, if the contact position of the button panel 30 pressed by the user is at the edge of the button panel 30 corresponding to the position of one of the transmission flaps 11, then when the transmission flap 11 on this side is pressed down by force, it will drive the linked segment 122 connected to it to move downward synchronously. At this time, the torsion segment 123 connected to the linked segment 122 will be folded to generate torque, which is transmitted to the shaft segment 121 to drive the shaft segment 121 to rotate synchronously with the linked segment 122 on this side, and at the same time, the torque is further transmitted to the torsion segment 123 and the linked segment 122 at the other end through the shaft segment 121, thereby driving the other transmission flap 11 connected to it to flip downward synchronously through the linked segment 122 at the other end, thereby realizing the synchronous downward linkage control of the two transmission flaps 11, and then realizing the effective triggering of the reset function module 50, achieving accurate and sensitive control of the corresponding circuit on and off, and thereby realizing the switch control of the corresponding lamps or electrical appliances.

[0058] On this basis, the two linkage sections 122 on the same linkage torsion bar 12 are gap-matched to form a torsion gap 124 that is aligned with the end of the trigger hinge shaft 10. The torsion gap 124 can leave sufficient assembly space for the trigger hinge shaft 10 and other related action mechanisms to avoid structural interference with the trigger hinge shaft 10 and other action parts, thereby ensuring the operating efficiency of the reset switch assembly and making its operation more sensitive and accurate.

[0059] It is not difficult to see that through the mutual cooperation of the shaft section 121, the torsion section 123 and the linkage section 122, the linkage torsion bar 12 forms a C-shaped structure, so as to better adapt to structural parts such as the positioning panel 20, so that the component structure of the reset switch assembly is more regular and the assembly is more stable and reliable.

[0060] Specifically, there are two linkage torsion bars 12, and the two linkage torsion bars 12 are respectively arranged on both sides of the transmission flap 11 along the axial direction of the trigger hinge shaft 10. The two symmetrically arranged linkage torsion bars 12 cooperate with each other to further improve the consistency of the flipping action between the two transmission flaps 11, optimize the linkage effect, and make the button triggering of the reset switch assembly more sensitive and reliable.

[0061] In practical applications, the main panel structure of the reset switch assembly is usually square. That is, frame structural members or plate-shaped structural members such as the fixing frame 40, the positioning panel 20, and the button panel 30 are all square. In this way, the outer ends of the two drive flaps 11 can be respectively hinged to one set of opposite sides of the positioning panel 20, and the two linkage torsion bars 12 are respectively arranged on the other set of opposite sides of the positioning panel 20. In this way, the symmetric arrangement directions of the two linkage torsion bars 12 and the two drive flaps 11 are perpendicular to each other, optimizing the structural layout and action effect of the corresponding components.

[0062] More specifically, a linkage slot 111 is provided on the side of the drive flap 11, and the linkage segments 122 are rotationally inserted into the linkage slots 111 one by one. The linkage slot 111 can be appropriately engaged and adapted with the linkage segment 122 to prevent the linkage segment 122 from loosening or misaligning along its radial direction. On this basis, it is ensured that the linkage segment 122 can rotate smoothly within the linkage slot 111, thereby ensuring the linkage effect of the corresponding action mechanism.

[0063] Correspondingly, a rotation slot 22 is provided on the positioning panel 20, and the rotation shaft segment 121 is rotationally inserted into the rotation slot 22. The rotation slot 22 can be appropriately engaged and adapted with the rotation shaft segment 121 to prevent the rotation shaft segment 121 from loosening or misaligning along its radial direction. On this basis, the rotation shaft segment 121 can rotate smoothly within the rotation slot 22, thereby ensuring the linkage effect of the corresponding mechanism.

[0064] In practical applications, the number of rotation slots 22 adapted to the same rotation shaft segment 121 can be 1, or 2 or more. The coordinated arrangement of multiple rotation slots 22 can ensure the reliable positioning and assembly and rotational stability of the rotation shaft segment 121. Of course, the specific number of rotation slots 22 adapted to the same rotation shaft segment 121 can be flexibly adjusted according to the actual assembly space and working conditions requirements. In principle, as long as it can meet the actual application needs of the reset switch assembly, it is acceptable.

[0065] Furthermore, a limiting support rod 23 is convexly provided on the top surface of the positioning panel 20, and a limiting tongue 231 is bent at the top end of the limiting support rod 23. A limiting hole 112 is penetrated along the moving direction of the button panel 30 on the drive flap 11, and the limiting support rods 23 are inserted into the limiting holes 112 one by one, and the bottom surface of the limiting tongue 231 can be in abutting fit with the top surface of the drive flap 11.

[0066] After the assembly is in place, by using the alignment and insertion adaptation of the limiting support rod 23 and the limiting hole 112, reliable structural positioning of the positioning panel 20 and the drive flap 11 along the main extension plane direction can be formed, avoiding structural loosening or misalignment between the two.

[0067] On this basis, through the alignment and adaptation of the limiting tongue 231 and the transmission flap 11, a reliable structural limit can be formed for the transmission flap 11 in the reciprocating movement direction of the key panel 30. In particular, it can effectively prevent the transmission flap 11 from being misaligned and disengaged due to excessive upward movement when the transmission flap 11 rebounds and resets upward together with the key panel 30, thereby further improving the assembly structure stability and component movement reliability of the reset switch assembly.

[0068] In practical applications, the limiting support rod 23 can also be arranged on the fixed frame 40 and penetrate through the positioning panel 20 and the transmission flap 11 in sequence, so as to form a coordinated limit for the transmission flap 11 and the positioning panel 20 by using the clamping structure between the limiting tongue 231 and the transmission flap 11.

[0069] Furthermore, an elastic arm 113 capable of driving the transmission flap 11 to flip upward and reset is arranged between the transmission flap 11 and the positioning panel 20, and the elastic arm 113 protrudes from the bottom of the transmission flap 11.

[0070] Specifically, the elastic arm 113 is an arched member with a middle part bulging towards the direction where the positioning panel 20 is located, and the bottom end of the middle part of the elastic arm 113 can be in abutting fit with the positioning panel 20. When the transmission flap 11 flips downward synchronously with the pressing down of the key panel 30, the bulging part in the middle of the elastic arm 113 is compressed and undergoes appropriate elastic deformation, so as to form an appropriate structural buffer and limit for the downward flipping action of the transmission flap 11, and avoid structural impact or misalignment caused by excessive movement during the downward flipping of the transmission flap 11; when the key panel 30 rebounds and resets upward, the transmission flap 11 releases the downward pressure on the elastic arm 113, so that the elastic arm 113 rebounds under the action of the elastic reset force of its middle bulging structure, and thereby jacks up the transmission flap 11 upward, so as to drive the transmission flap 11 to flip upward and reset, and further assist the upward rebound and reset of the key panel 30, thereby ensuring the efficient and smooth rebound and reset of the transmission flap 11 and the key panel 30, so as to further improve the action efficiency of the reset switch assembly and optimize its operation and use convenience.

[0071] Generally, elastic arms 113 can be correspondingly arranged at positions such as the edges and corners at the bottom of the transmission flap 11, so as to optimize the stress distribution during the matching action between the transmission flap 11 and the elastic arms 113, avoid local stress concentration of the transmission flap 11, and further improve the working condition tolerance and service life of the transmission flap 11.

[0072] On the other hand, a positioning groove 114 is recessed in the outer end portion of the transmission flap 11 in a direction perpendicular to the axis of the trigger hinge shaft 10. Positioning bosses 24 that protrude and extend into the positioning groove 114 one by one are provided on the inner side wall of the positioning panel 20. A positioning hinge hole 241 penetrates through the middle of the positioning boss 24 along the axial direction of the trigger hinge shaft 10. Positioning hinge shafts 115 that protrude and are inserted into the positioning hinge hole 241 one by one are provided on the inner wall of the positioning groove 114, and the positioning hinge shafts 115 are rotationally matched with the positioning hinge holes 241.

[0073] Through the alignment and cooperation of the positioning boss 24 and the positioning groove 114, further limitation can be formed on the fitting structure between the transmission flap 11 and the positioning panel 20 in the direction of the main extension plane. Moreover, the positioning groove 114 can provide sufficient layout space for protruding components such as the positioning boss 24 and the positioning hinge shaft 115, so as to prevent the protruding structures of these components from interfering with the main structural components such as the positioning panel 20.

[0074] In addition, the transmission flap 11 includes a support portion 116 and a transmission portion 117 arranged in sequence from its outer end to its inner end. The trigger hinge shaft 10 is hinged to the free end of the transmission portion 117, and the positioning groove 114 and the positioning hinge shaft 115 are both located at the free end of the support portion 116; the thickness of the support portion 116 increases from its free end to its connection end with the transmission portion 117. This kind of thickness increasing structure can further improve the structural strength of the support portion 116, making the overall structure of the transmission flap 11 more reliable.

[0075] In addition, a plurality of transmission bosses 118 that can be in contact and cooperation with the key panel 30 protrude and are arranged on the top surface of the transmission flap 11. These transmission bosses 118 can be arranged in an array or locally arranged according to the actual working conditions. Using the transmission bosses 118 as the direct contact and cooperation structure with the key panel 30 can further avoid the structural impact between the key panel 30 and the transmission flap 11 during the operation of the key panel 30, optimize the linkage cooperation effect and transmission efficiency between the two, avoid local stress concentration of the transmission flap 11 and the key panel 30, and improve the reliability of the component structure.

[0076] In summary, in the reset switch assembly provided in the present utility model, during its operation and use, the two drive flaps cooperate with each other to form an inner turning action mechanism that is hinged in the middle and synchronously linked with the key panel, and the outer end rotates around a fixed axis. Thus, when the user presses the key panel, if the pressing contact part is in the middle of the key panel, the inner end of the drive flap and the trigger hinge shaft will be linked and pressed down together with the key panel until they contact the trigger end of the reset function part module and press down the trigger end to trigger the reset function part module. Then, the circuit switch mechanism is driven by the reset function part module to turn on or off the circuit; if the user's pressing contact part is at the end, edge or other non-central area of the key panel, the drive flap receives the downward pressure transmitted from the key panel, so that the inner end of the drive flap is pressed down synchronously with the key panel, and the inner end of the drive flap is used to drive the trigger hinge shaft to be pressed down synchronously until they contact the trigger end of the reset function part module and press it down, thereby triggering the reset function part module, and then the circuit switch mechanism is driven by the reset function part module to turn on or off the corresponding circuit. The reset switch assembly uses the transmission mechanism as a transmission trigger component arranged between the key panel and the reset function part module in a linkage manner, so that no matter which part of the key panel the user presses, the action of the reset function part module can be effectively triggered, and the on-off control of the corresponding circuit can be realized, thereby controlling the turning on or off of the corresponding lamp or electrical appliance. Therefore, the operation efficiency of the reset switch assembly is significantly improved, its key triggering is more sensitive and accurate, and the operation effect of the reset switch assembly is correspondingly optimized, making its operation more convenient and reliable.

Specific examples are used in this article to elaborate on the principle and implementation mode of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
