Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical appliances, specifically to a wall switch. Background Technology

[0002] Switches, as common electrical accessories in daily life, have seen their technology stabilize after decades of development. As indispensable electrical products, switches are ubiquitous and universal. A high-performance switch should have a longer lifespan, a wider range of applications, and be generally not easily adjusted or replaced after installation. The feel of the switch is also an aspect of evaluating its quality, but this is subjective; different users have different preferences for the force required to turn it on. Some people find a heavier switch to be safer and more reliable, while others prefer a light and quiet operation.

[0003] However, existing switches are designed with a fixed feel at the factory, regardless of the brand, series, or structure. The feel of the switch cannot be adjusted, which cannot meet the different needs of customers for the feel of the switch. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wall switch with adjustable feel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a wall switch, including a moving contact, a stationary contact, a button, and a housing that accommodates the moving contact, the stationary contact, and the button. The button is rotatably configured and has a through-hole facing the moving contact. An elastic element, a rocker arm, and an adjustable element are provided in the mounting hole. One end of the elastic element is connected to one end of the rocker arm, and the other end is connected to one end of the adjustable element. The adjustable element can change its position in the mounting hole and is used to adjust the elastic force of the elastic element.

[0007] In one possible implementation, the adjustable element is a knob, one end of which has an operating part and the other end has a first thread, and the mounting hole of the knob has a second thread that mates with the first thread.

[0008] In one possible implementation, the first thread is an external thread that protrudes outward or an internal thread that is recessed inward on the side of the knob, and the second thread is an internal thread that is recessed inward or an external thread that protrudes outward on the inside of the mounting hole.

[0009] In one possible implementation, the adjustable element is a push rod, one end of which is an operating part, and the other end includes a first engaging part with elasticity, and the mounting hole of the button has a second engaging part that engages with the first engaging part.

[0010] In one possible implementation, the first engaging portion is a plurality of teeth or grooves provided on the side of the push rod, and the second engaging portion is a plurality of grooves or teeth provided inside the mounting hole.

[0011] In one possible implementation, at least one end of the adjustable member has a first limiting portion, and the mounting hole of the button is provided with a second limiting portion that cooperates with the first limiting portion. The cooperation of the first limiting portion and the second limiting portion allows the adjustable member to have a fixed displacement range within the mounting hole.

[0012] In one possible implementation, the lever is made of metal, and the other end of the lever is a drive portion that slides with a moving contact. A graphene layer is provided on the drive portion of the lever.

[0013] In one possible implementation, the graphene layer has a curved structure.

[0014] In one possible implementation, the rocker arm further includes a connecting column and a fixed column. One end of the connecting column is connected to the driving part, and the other end is connected to the fixed column. The diameter of the cross-section of the connecting column is larger than the diameter of the cross-section of the fixed column. A blocking part is formed at the connection between the connecting column and the fixed column. One end of the elastic member is mounted on the fixed column and abuts against the blocking part.

[0015] In one possible implementation, the top side of the middle portion of the moving contact has a sliding groove, the bottom side of the middle portion is supported on a fulcrum, the driving part of the swing arm is placed in the sliding groove and slides in cooperation with the bottom wall of the sliding groove, and after the driving part slides to both sides of the fulcrum, it can drive the moving contact to swing around the fulcrum to both sides respectively.

[0016] In one possible implementation, the housing includes a cover plate, a middle cover, and a base. The moving contact and the stationary contact are disposed within the base. The middle cover is fitted onto the base and has a first through hole. A button is rotatably mounted on the middle cover and has an end with an elastic element and a swing arm passing through the first through hole. The cover plate is rotatably mounted on the middle cover and is capable of driving the button to swing.

[0017] In one possible implementation, the button includes a support portion and a pressing portion that are fixedly connected, the support portion and the pressing portion being arranged perpendicularly to form a "T"-shaped button, the mounting hole being disposed within the support portion, and the support portion passing through the first through hole.

[0018] In one possible implementation, the pressing part has protrusions on opposite sides of its middle portion, and two support platforms are correspondingly provided on the middle cover. The pressing part is rotatably mounted on the two support platforms through the two protrusions to form a rotating shaft. The middle portion of the middle cover is provided with the first through hole between the two support platforms.

[0019] In one possible implementation, the pressing part is a long strip structure with third limiting parts at both ends, and a corresponding fourth limiting part is also provided inside the middle cover. When one end of the pressing part is pressed, the third limiting part and the fourth limiting part at that end abut against each other, so that the button has a fixed swing angle.

[0020] In one possible implementation, the wall switch includes a moving contact and two stationary contacts. The moving contact has a long plate-like structure, with a moving contact point at each end. The moving contact point has a sliding groove bent in the middle. Each stationary contact has a corresponding stationary contact point.

[0021] In one possible implementation, the wall switch includes three terminals: one terminal is integrally formed with a pivot and electrically connected to a moving contact via the pivot; the other two terminals are integrally formed with two stationary contacts, respectively.

[0022] Compared with existing technologies, this utility model wall switch includes a moving contact, a stationary contact, a button, and a housing that accommodates the moving contact, stationary contact, and button. The button is rotatably configured and has a through-hole in the direction of the moving contact for mounting an elastic element, a rocker arm, and an adjustable element. One end of the elastic element is connected to the adjustable element, and the other end is connected to the rocker arm. The other end of the rocker arm includes a driving part for driving the moving contact to swing around a fulcrum and contact or disconnect from the stationary contact. The adjustable element can compress or release the elastic element, changing the initial elastic force of the elastic element, thereby changing the minimum force required to drive the button to swing so that the moving contact and stationary contact can contact or close, thus changing the feel of operating the wall switch. By setting an adjustable element connected to the elastic element on the button of the wall switch, the initial elastic force of the elastic element can be adjusted. The elastic element is also connected to the rocker arm. With the swing amplitude of the rocker arm remaining constant, the feel of operating the switch can be adjusted according to the needs of different users, resulting in a better user experience.

[0023] Furthermore, the advantage of using knobs as adjustable components is that the degree of fine adjustment is higher, which can meet the comfort experience of more people.

[0024] Furthermore, using a push rod for adjustment eliminates the need for external tools, making it even more convenient and simple.

[0025] Furthermore, the use of a metal lever with a graphene layer on the drive section reduces friction between the moving contact and the lever, resulting in a better feel for the wall switch. It also has good conductivity and requires no lubricant.

[0026] Furthermore, the curved graphene layer helps reduce friction between the moving contact and the metal lever, improves the smoothness of the switch feel, enhances conductivity, and increases switching capability. Attached Figure Description

Detailed Implementation

[0037] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0038] The wall switch includes a button 1, a lever 2, an elastic element 3, a contact assembly 4, and a housing for accommodating the above components. The housing includes a cover plate 01. The elastic element 3 connects the button 1 and the lever 2. The contact assembly 4 includes at least one set of moving contacts 41 and stationary contacts 42. When the cover plate 01 is pressed, it drives the button 1 to swing, which in turn drives the lever 2 to swing. The end of the lever 2 away from the button 1 contacts the moving contact 41, slides against it, and presses against it, causing the moving contact 41 to swing and contact or break contact with the stationary contact 42, thus connecting or disconnecting the circuit. The elastic element 3 provides a buffer when the lever 2 contacts the moving contact 41, and also provides pressure when the lever 2 presses against the moving contact 41, enhancing the stability of the structure. When the moving contact 41 and the stationary contact 42 are in contact, it reduces the wobbling between the button 1, the moving contact 41, and the stationary contact 42, thereby enhancing the switching capability.

[0039] like Figure 1 and Figure 2 As shown, this utility model provides a wall switch, including a button 1, a lever 2, an elastic element 3, a contact assembly 4, and a housing accommodating the contact assembly 4 and the button 1. The contact assembly 4 includes a terminal block, a moving contact 41, and a stationary contact 42. The terminal block is electrically connected to either the stationary contact 42 or the moving contact 41 for connecting external wires. The button 1 is rotatably configured and has a through mounting hole 11 facing the moving contact 41. The elastic element 3, the lever 2, and the contact assembly 41 are disposed within the mounting hole 11. Adjustable component 5, preferably made of insulating material to improve insulation capability, has one end of elastic component 3 connected to one end of rocker arm 2 and the other end connected to one end of adjustable component 5. The other end of rocker arm 2 is a drive part 21 that slides with moving contact 41. The drive part 21 is used to drive moving contact 41 to swing around fulcrum 43 to contact or disconnect from stationary contact 42. Adjustable component 5 can extend or retract relative to mounting hole 11, which can compress or release elastic component 3 and change the elastic force of elastic component 3. Elastic component 3 can be, but is not limited to, compression spring, spring, etc.

[0040] This utility model wall switch includes a moving contact 41, a stationary contact 42, a button 1, and a housing that accommodates the moving contact 41, stationary contact 42, and button 1. The button 1 is rotatably configured and has a through mounting hole 11 in the direction of the moving contact 41 for mounting an elastic element 3, a rocker arm 2, and an adjustable element 5. One end of the elastic element 3 is connected to the adjustable element 5, and the other end is connected to the rocker arm 2. The other end of the rocker arm 2 includes a driving part 21 for driving the moving contact 41 to swing around a fulcrum 43 to contact or disconnect from the stationary contact 42. By operating the adjustable element 5, the position of the adjustable element 5 can be changed within the mounting hole 1. Changing the position of the adjustable element 5 can compress or release the elastic element 3, changing the initial elastic force of the elastic element 3, thereby changing the minimum force required to drive the button 1 to swing so that the moving contact 41 and the stationary contact 42 can contact or close, thus changing the feel of operating the wall switch. By setting an adjustable part 5 connected to the elastic element 3 on the button 1 of the wall switch, the initial elastic force of the elastic element 3 can be adjusted. The elastic element 3 is also connected to the swing arm 2. With the swing arm 2 swinging amplitude unchanged, the lightness or heaviness of the switch can be adjusted according to the needs of different people, resulting in a better user experience.

[0041] Preferably, at least one end of the adjustable member 5 has a first limiting part, and the mounting hole 11 of the button 1 is provided with a second limiting part that cooperates with the first limiting part. The cooperation of the first limiting part and the second limiting part ensures that the adjustable member 5 has a fixed displacement range within the mounting hole 11, preventing the adjustable member 5 from compressing the elastic member 3 and exceeding the elastic deformation range of the elastic member 3, thus preventing the elastic member 3 from failing to return to its original state and damaging the elastic member 3. It also prevents the adjustable member 5 from falling out of the mounting hole 11 during the release of the elastic member 3, which would affect the service life and user experience of the wall switch. Elastic deformation refers to the change in the relative position between points of a solid when subjected to external force. When the external force is removed, the solid returns to its original state, which is called "elastic deformation." When the range of elastic deformation of the solid is exceeded, the solid will not be able to return to its original state.

[0042] When the adjustable part 5 is compressed inward to its maximum compression, the elastic force of the elastic part 3 is at its maximum, and the wall switch feels the heaviest at this time. When the adjustable part 5 is released outward to its farthest distance, and the first limit part and the second limit part abut against each other, the elastic force of the elastic part is at its minimum, and the wall switch feels the lightest at this time. Since the elastic part 3 always resists the adjustable part 5 during the adjustment process, the mechanism achieves self-locking. Without external force intervention, the feel is locked and will not change.

[0043] Preferred, such as Figure 3As shown, the adjustable component 5 is a knob. One end of the knob has an operating part 51, and the other end has a first thread 52. The mounting hole 11 of the knob 1 has a second thread 53 that mates with the first thread 52. Rotating the knob inward compresses the elastic element 3, increasing the elastic force; rotating it outward releases the elastic element 3, decreasing the elastic force. The advantage of using a knob is that it allows for more precise adjustment, satisfying the comfort needs of a wider range of users. Figure 3 This is a disassembly diagram of button 1, lever 2, elastic element 3, and adjustable element 5.

[0044] Furthermore, the first thread 52 is an external thread protruding outward on the side of the knob, i.e., a screw thread, and the second thread 53 is an internal thread recessed inward on the inside of the mounting hole 11. Alternatively, the first thread 52 is an internal thread recessed inward on the side of the knob, and the second thread 53 is an external thread protruding outward on the inside of the mounting hole 11. The operating part 51 is a flat or Phillips head groove, used to rotate the knob by engaging a flat or Phillips head screwdriver. Of course, the operating part 51 is not limited to the structure described above. For example, it can also be a raised structure that facilitates external driving, or other similar structures are also within the scope of protection of this application, and will not be described in detail here.

[0045] Furthermore, the first limiting part can be a protruding boss of the knob operating part 51, and a ring-shaped baffle can be set around one end of the knob. The second limiting part is also the boss, which can also be set as a ring-shaped baffle. When the knob is rotated inward to compress the elastic element 3, the ring-shaped baffle at the end of the knob operating part 51 abuts against the ring-shaped baffle in the mounting hole 11, so that the adjustable part 5 is limited and cannot continue to compress the elastic element 3. When the knob is rotated outward to release the elastic element 3, the rotation end point of the external thread of the knob abuts against the internal thread, so that the knob cannot continue to be rotated, thereby achieving the limiting effect.

[0046] Preferably, the adjustable component 5 is a push rod, with one end being an operating part 51 and the other end being a first engaging part with elasticity. The mounting hole 11 of the button 1 has a second engaging part that mates with the first engaging part. Pressing the push rod inward compresses the elastic component 3, increasing the elastic force; pulling the push rod outward releases the elastic component 3, reducing the elastic force. Using a push rod for adjustment eliminates the need for external tools, making it more convenient and simple.

[0047] Furthermore, the first engaging portion consists of multiple teeth or grooves on the side of the push rod, and the second engaging portion consists of multiple grooves or teeth on the inner side of the mounting hole 11; the operating portion 51 is a boss or pull ring that can be used with external tools to push and pull the push rod. In this embodiment, the engagement between the push rod and the mounting hole 11 is similar to the engagement between a shaft and a slide, with multiple teeth and grooves serving as multiple limiting structures to adjust the pressure level of the wall switch.

[0048] Furthermore, the first limiting part can be a boss protruding at both ends of the push rod, and can be configured as annular baffles around both ends of the push rod. The second limiting part can also be the boss or annular baffles. When the push rod compresses the elastic member 3 inward, the annular baffle at the end of the push rod operating part 51 abuts against the annular baffle in the mounting hole 11, so that the push rod is limited and cannot continue to compress the elastic member 3. When the push rod is pulled outward to release the elastic member 3, the annular baffle at the other end of the push rod abuts against the annular baffle in the mounting hole 11, so that the push rod cannot continue to be pulled outward, thereby achieving the limiting effect.

[0049] Preferably, the swing arm 2 is made of a plastic material with excellent mechanical properties, such as PA66, which can save on product production costs and reduce product weight.

[0050] Preferred, Figure 4 A schematic diagram of the structure of a pendulum 2 is shown, as follows: Figure 4 As shown, the swing arm 2 is made of metal, and a graphene layer 22 is provided on the driving part 21 of the swing arm 2. The graphene layer 22 can be deposited on the driving part 21 of the swing arm 2 by an electroplating process.

[0051] The rocker arm 2 is made of metal, and a graphene layer 22 is provided on the drive part 21 of the rocker arm 2. This can reduce the friction between the moving contact 41 and the rocker arm 2, making the wall switch feel better to use. It has good conductivity and does not require the addition of lubricant.

[0052] Furthermore, the graphene layer 22 has a curved structure, which helps to reduce the friction between the moving contact 41 and the metal lever 2, improve the smoothness of the switch feel, enhance conductivity, and improve the switching capability.

[0053] In another embodiment, the graphene layer 22 may not be provided on the drive part 21 of the rocker arm 2. The drive part 21 may be a bent copper part, and then lubricating oil may be applied. By applying lubricating oil, the friction between the drive part 21 of the rocker arm 2 and the moving contact 41 (or hardware) can be reduced.

[0054] Preferred, Figure 5 A schematic diagram of another type of pendulum 2 is shown, such as... Figure 5As shown, the drive part 21 of the swing arm 2 has a conical structure. The conical structure of the drive part 21 can save internal space and enhance the flexibility and sensitivity of the swing arm 2.

[0055] Preferred, such as Figure 4 and Figure 5 As shown, the swing arm 2 also includes a connecting column 23 and a fixing column 24. One end of the connecting column 23 is connected to the driving part 21, and the other end is connected to the fixing column 24. The diameter of the cross-section of the connecting column 23 is larger than the diameter of the cross-section of the fixing column 24. A blocking part 25 is formed at the connection between the connecting column 23 and the fixing column 24. One end of the elastic member 3 is installed on the fixing column 24 and abuts against the blocking part 25.

[0056] The swing arm 2 includes a connecting post 23 and a fixing post 24 with different cross-sectional diameters, so that the connection between the connecting post 23 and the fixing post 24 forms a blocking part 25, which facilitates the limiting and fixing of the elastic element 3.

[0057] Preferred, such as Figure 6 and Figure 7 As shown, the contact assembly 4 is provided with a fulcrum 43, which is fixedly mounted on the housing. The top side of the middle portion of the moving contact 41 has a sliding groove 44, and the bottom side of the middle portion is supported on the fulcrum 43. The driving part 21 of the swing rod 2 is placed in the sliding groove 44 and slides in cooperation with the bottom wall of the sliding groove 44. After the driving part 21 slides to both sides of the fulcrum 43, it can drive the moving contact 41 to swing to both sides around the fulcrum 43. Figure 7 A schematic diagram of the structure showing the interaction between the button 1, the lever 2, the elastic element 3, and the adjustable element 5 with the contact assembly 4 is shown.

[0058] A sliding groove 44 is provided on the top side of the middle part of the moving contact 41, and the bottom side of the middle part of the moving contact 41 is supported on the fulcrum 43, so that the driving part 21 of the swing rod 2 is placed in the sliding groove 44, which facilitates the swing rod 2 to slide to both ends of the sliding groove 44, driving the moving contact 41 to rotate around the fulcrum 43, so that the moving contact is close to or separates from the corresponding stationary contact.

[0059] Preferred, such as Figure 1 As shown, the housing includes a cover plate 01, a middle cover 02, and a base 03 that are stacked and fixedly installed along the thickness direction of the wall switch. The moving contact 41 and the stationary contact 42 are disposed in the base 03. The middle cover 02 covers the base 03 and has a first through hole. The button 1 is rotatably mounted on the middle cover 02 and has an elastic element 3 and a swing rod 2, one end of which passes through the first through hole. The cover plate 01 is rotatably mounted on the middle cover 02 and can drive the button 1 to swing.

[0060] Further, such as Figure 8As shown, the button 1 includes a fixedly connected support portion 12 and a pressing portion 13. The support portion 12 and the pressing portion 13 are arranged perpendicularly to form a "T" shape for the button 1. The mounting hole 11 is provided inside the support portion 12, and the support portion 12 passes through the first through hole. After the button 1 is installed on the housing, the support portion 12 is aligned with the thickness direction of the wall switch.

[0061] Further, such as Figure 1 As shown, the pressing part 13 has protrusions 131 on two opposite sides of its middle part. The middle cover 02 has two corresponding support platforms 132. The pressing part 13 is rotatably mounted on the two support platforms 132 through the two protrusions 131 to form a rotating shaft. The middle part of the middle cover 02 is provided with the first through hole between the two support platforms 132. Press the two ends of the cover plate 01, and the button 1 can rotate around the rotating shaft.

[0062] In a preferred embodiment, in order to reduce the thickness of the wall switch, the distance between the cover plate 01 of the wall switch and the rotation axis of the button 1 can be reduced as much as possible, so that the pressing range of the cover plate 01 is reduced, and the structure of the wall switch is more exquisite and beautiful.

[0063] Further, such as Figure 8 As shown, the pressing part 13 is a long strip structure with a third limiting part 133 at both ends. A corresponding fourth limiting part is also provided inside the middle cover 02. When one end of the pressing part 13 is pressed, the third limiting part 133 and the fourth limiting part at that end abut against each other, so that the button 1 has a fixed swing angle.

[0064] Furthermore, the button 1 is integrally cast, which can reduce assembly time and increase production capacity.

[0065] In another possible implementation, the button 1 can also be mounted by a support portion 12 and a pressing portion 13, wherein the support portion 12 is provided with a first mounting portion and the pressing portion 13 is provided with a second mounting portion that cooperates with the first mounting portion.

[0066] Furthermore, the first mounting part can be a snap-fit ​​structure, and the second mounting part can be a slot structure. The snap-fit ​​structure and the slot structure cooperate to fix the button 1 to the support part 12 and the pressing part 13. The advantage of this is that it is easy to disassemble, convenient for later maintenance, and easy to replace damaged parts, thus saving costs.

[0067] Preferred, such as Figure 8As shown, the third limiting part 133 is a first protrusion protruding from both ends of the pressing part 13 toward the middle cover 02, and the fourth limiting part is a second protrusion protruding from both ends of the middle cover 02 toward the cover plate 01. Since the button 1 is swingable, in order for the contact surfaces of the first protrusion and the second protrusion to fit together completely, the contact surfaces of the first protrusion and / or the second protrusion can be set as inclined surfaces. The specific inclination angle is designed according to the swing angle of the button 1.

[0068] In another possible implementation, the third limiting part 133 may not have the first boss, or the third limiting part 133 may be configured as a groove structure that cooperates with the second boss, which also falls within the protection scope of this application.

[0070] Further, such as Figure 6 , Figure 7 and Figure 9 As shown, the contact assembly 4 of the wall switch of this application includes one moving contact 41 and two stationary contacts 42. The moving contact 41 has a long plate-like structure, with a moving contact point at each end. The moving contact point has a sliding groove 44 bent in the middle. Each stationary contact 42 has a corresponding stationary contact point, and the moving contact point corresponds one-to-one with the stationary contact point. The two ends of the moving contact 41 can swing back and forth with the fulcrum 43 as the support point, so that the moving contact point at both ends contacts or disconnects from the corresponding stationary contact point. Figure 6 and Figure 9 The diagram shows the structure of the contact assembly 4 from two different perspectives.

[0071] Further, such as Figure 6 , Figure 7 and Figure 9 As shown, the contact assembly 4 of the wall switch of this application includes three terminals. One terminal is integrally formed with the pivot 43 and is electrically connected to the moving contact 41 through the pivot 43. The other two terminals are integrally formed with the two stationary contacts 42 respectively. Preferably, the other two terminals are integrally formed with the stationary contacts 42. Obviously, only one stationary contact 42 can be provided to control the on / off state of only one circuit.

[0072] The three terminals of the contact assembly 4 are L terminal, N terminal and L1 terminal, which can be used in single-pole double-control switches. There are multiple wiring methods for single-pole double-control switches. For example, two sets of wall switches are connected in series in the circuit. When both sets of wall switches are turned on at the same time, the entire circuit will be turned on and the electrical equipment can be used. Alternatively, two sets of wall switches are connected in parallel in the circuit. The two sets of wall switches can control the start and stop of the electrical equipment respectively.

[0073] Furthermore, the contact assembly 4 of this application may also include two terminals, one moving contact 41 and two stationary contacts 42. The two terminals are electrically connected to the two stationary contacts 42 respectively. The moving contact 41 includes two moving points, and each of the two stationary contacts includes one stationary contact. One moving contact corresponds to one stationary contact. The two terminals can be connected in series in the circuit to serve to connect or disconnect the circuit.

[0074] Furthermore, the middle cover 02 is provided with a plurality of first limiting structures, which limit the button 1.

[0075] The base 03 is provided with a plurality of second limiting structures, which fix the contact assembly 4 to the base 03.
