Description

Technical Field

[0001] The utility model relates to the field of low-voltage electrical appliances, in particular to a wall switch. Background Art

[0002] Wall switches are commonly used electrical accessories that are frequently used in daily life and are electrical products with certain decorative properties.

[0003] Existing wall switches operate by snapping or fitting a panel and a button. Pressing the panel pries the button, which rotates together, to activate the switch. Existing buttons are generally small in size. When used with large panels, these buttons often protrude significantly from the panel. This can lead to panel deformation or mismatching during activation, making it difficult to align the on / off actuation angles between the panel and the button. This can cause noticeable jerking of the movable contact when the button is in contact with the movable contact, and can also cause electrical corrosion on the movable contact's support plate, impacting the lifespan of the wall switch.

[0057] The following embodiments are given in conjunction with the accompanying drawings to further illustrate the specific implementation of the present utility model. The protection scope of the present utility model is not limited to the description of the following embodiments.

[0058] like Figure 1As shown, the present application provides a wall switch, including a button assembly 1, a pressure plate 2, a contact assembly 3, a mounting bracket 4 and a panel 5. The mounting bracket 4 includes a mounting slot 41 and mounting holes 42 on both sides of the mounting slot 41. Screws can connect the wall switch to the dark box on the cavity through the mounting holes 42. The contact assembly 3, pressure plate 2, button assembly 1 and panel 5 are installed in sequence. The contact assembly 3 includes at least one moving contact 32 and at least one static contact 34. The contact assembly 3 and pressure plate 2 are located in the mounting slot 41. The pressure plate 2 limits the contact assembly 3 in the mounting slot 41. The panel 5 and the mounting bracket 4 are rotatably installed to cover the mounting slot 41. Figure 5 and Figure 6 As shown, the mounting frame 4 is provided with a first shielding portion 45, a mounting groove 41 and a second shielding portion 46 in sequence along the first direction, and the rotation axis of the panel 5 is arranged along the second direction, and the first direction is perpendicular to the second direction.

[0059] like Figure 1-Figure 4 As shown, the button assembly 1 includes a button 12, a push rod 13 and a spring 14 connected in sequence. The button 12 includes a linkage plate 121 and a linkage rod 122. One end of the linkage rod 122 is perpendicular to the linkage plate 121, and the other end is a driving end. The button assembly 1 is rotatably mounted on the pressure plate 2 and the driving end of the linkage rod 122 passes through the pressure plate 2. The spring 14 is connected between the driving end and the push rod 13. The push rod 13 is connected to the contact assembly 3 for driving the moving contact 32. The panel 5 swings to drive the linkage plate 121 to swing and drive the moving contact 32 to switch the state of the contact assembly 3.

[0060] The flat structure of the linkage plate 121 of the button 12 increases the contact area between the button 12 and the panel 5. When the panel 5 is driven to swing, it avoids the problem of excessive difference in area between the panel 5 and the button 12, which may cause deformation of the panel or mismatching, which may cause inconsistent driving angles between the panel 5 and the button 12. It also improves the sensitivity of the drive. Figure 3 and Figure 4 1 is a schematic structural diagram of the front and back sides of the button 12 of this embodiment.

[0061] Preferably, Figure 1 and Figure 2 As shown, the area of ​​the linkage plate 121 is larger than the area of ​​the pressure plate 2, so that the linkage plate 121 basically covers the pressure plate 2, playing a role of squeezing and limiting the pressure plate 2. Specifically, the length of the linkage plate 121 in the first direction is greater than or equal to the length of the pressure plate 2 in the first direction, and the length of the linkage plate 121 in the second direction is greater than the length of the pressure plate 2 in the second direction, so that the linkage plate 121 completely covers the pressure plate 2.

[0062] Preferably, Figure 5-Figure 6As shown, the area of ​​the linkage plate 121 of the button 12 is enlarged, and basically completely covers the installation groove 41. The enlarged area provides dustproof and safety protection for the interior of the installation groove 41.

[0063] Further, such as Figure 6 As shown, the linkage plate 121 is at least partially located in the mounting groove 41. The area of ​​the linkage plate is substantially equal to the area of ​​the mounting groove, but slightly smaller. The linkage plate swings in the mounting groove and completely covers the mounting groove 41, providing dustproof, safety protection, lightness, and beautiful appearance. Figure 2 As shown, when the linkage plate 121 swings to one side and contacts the pressure plate 2, the side of the linkage plate 121 completely enters the installation groove 41, further reducing the thickness of the wall switch and enhancing the aesthetics of the wall switch.

[0064] Further, such as Figure 3-Figure 6 As shown, the length of the linkage plate 121 in the second direction is greater than the distance between the two mounting holes 42. Avoidance notches 123 are provided on two opposing sides of the linkage plate 121 in the second direction to avoid the two mounting holes 42. Specifically, the linkage plate 121 has protrusions facing each other at the middle of the two side walls in the second direction. The two mounting holes 42 are respectively provided on the two protrusions. The two avoidance notches 123 respectively engage with the two protrusions to limit the linkage plate 121.

[0065] Preferably, Figure 2 and Figure 3 As shown, the driving end opening of the linkage rod 122 forms a spring mounting groove, the spring 14 is mounted in the spring mounting groove, the push rod 13 is at least partially located in the spring mounting groove to compress the spring 14, and the push rod 13 is able to slide in the spring mounting groove. Preferably, the push rod 13 is able to slide in the spring mounting groove and to swing relative to the linkage rod 122 within a certain range. In this way, the panel 5 and the button assembly 1 only need to rotate a small angle to drive the linkage rod 122 to swing past the equilibrium position. The push rod 13 can then swing a certain angle relative to the linkage rod 122, driving the movable contact 32 to swing a larger angle, thereby increasing the opening distance and improving the insulation distance.

[0066] Furthermore, the diameter of the push rod 13 is slightly smaller than the inner diameter of the spring mounting groove, and the push rod 13 can swing slightly relative to the button 12. When the panel 5 is pressed, the panel 5 drives the button assembly 1 to swing, and the button 12 drives the push rod 13 to swing through the spring mounting groove and the spring 14. The push rod 13 slides in the recessed area 35. When the push rod 13 slides to the curved surface 341 of the support plate 33, it reaches the equilibrium position. At this time, the spring 14 is compressed to the extreme. After the push rod 13 slides over the curved surface 341 of the support plate 33, the panel 5 and the button 12 continue to drive the push rod 13 to swing. At the same time, the spring 14 also drives the push rod 13 to swing slightly relative to the button 12, so that the panel 5 and the button assembly 1 only need to rotate a small angle to drive the moving contact 32 to swing a larger angle.

[0067] Preferably, Figure 2 As shown, the upper surface of the linkage plate 121 and the lower surface of the panel 5 are tightly fitted and detachably connected by snap-fit, thereby enhancing the linkage and synchronization effect between the panel 5 and the linkage plate 121 and reducing the thickness of the wall switch.

[0068] Furthermore, the linkage plate 121 includes a first snap-fit ​​structure, and the side of the panel 5 facing the linkage plate 121 includes a second snap-fit ​​structure, and the linkage plate 121 and the panel 5 are snap-fitted together by the first snap-fit ​​structure and the second snap-fit ​​structure.

[0069] Further, such as Figure 2 and Figure 4 As shown, the first snap-fit ​​structure includes at least one snap-fit ​​slot 11, and the second snap-fit ​​structure includes at least one snap-fit ​​hook 51; or the first snap-fit ​​structure includes at least one snap-fit ​​hook 51, and the second snap-fit ​​structure includes at least one snap-fit ​​slot 11, and the snap-fit ​​hook 51 and the snap-fit ​​slot 11 cooperate to achieve a snap-fit ​​connection.

[0070] Further, such as Figure 4 As shown, the slot 11 and the hook 51 are strip-shaped structures. In this embodiment, preferably, the first snap-fit ​​structure includes two parallel strip-shaped slots 11, which are distributed on both sides of the middle of the linkage plate 121. Correspondingly, the panel 5 includes two parallel hooks 51, and the two hooks 51 correspond to the two slots 11 in a one-to-one manner to achieve snap-fit ​​installation.

[0071] Preferably, Figure 1 and Figure 2As shown, the mounting frame 4 includes an integrally formed mounting frame box and a mounting plate, the mounting frame box protrudes out from the four sides of the mounting plate, and the middle opening of the mounting plate extends toward the inside of the mounting frame box to form the mounting groove 41. The panel 5 and the mounting plate are basically covered with the mounting plate after being rotated and installed, thereby increasing the drivable area of ​​the panel 5 and having better dustproof and safety protection effects. Preferably, the area of ​​the panel 5 is equal to the area of ​​the mounting plate. In this embodiment, the panel 5 and the mounting plate are both rectangular structures, the length of the panel 5 is equal to the length of the mounting plate, and the width of the panel 5 is equal to the width of the mounting plate.

[0072] Preferably, Figure 2-Figure 5 As shown, the button assembly 1 is rotatably mounted on the pressure plate 2. The pressure plate 2 includes a first through-hole 21, through which the linkage rod 122 passes to connect to the contact assembly 3. The linkage plate 121 is stacked above the pressure plate 2. Two opposing limit plates 22 are provided on the side of the pressure plate 2 facing the linkage plate 121 and on either side of the first through-hole 21. The limit plates 22 are provided with a slide groove 23. The linkage rod 122 of the button 12 includes two sliding protrusions 124 on either side. The sliding protrusions 124 slide within the slide groove 23. The linkage plate 121 includes two avoidance through-holes 126. The two limit plates 22 extend into the two avoidance through-holes 126, respectively, reducing the distance between the linkage plate 121 and the pressure plate 2, thereby reducing the thickness of the wall switch. Furthermore, the top of the slide groove 23 includes a notch to facilitate the installation of the sliding protrusion 124 within the slide groove 23.

[0073] Further, such as Figure 4 As shown, an elastic groove 128 is provided between the two escape holes 126. The two escape holes 126 and the elastic groove 128 form elastic sidewalls, and the two sliding protrusions 124 are respectively mounted on opposite sides of the elastic sidewalls. When the pressure plate 2 and the button assembly 1 are installed, the two elastic sidewalls can undergo plastic deformation, facilitating the installation of the pressure plate 2 and the button assembly 1.

[0074] Further, such as Figure 2 and Figure 3 As shown, the button 12 is in sliding contact with the pressure plate 2. The linkage rod 122 includes an arcuate contact portion 127. Two overlapping portions 24 are provided on both sides of the first through hole 21 along the first direction. The button 12 is mounted on the pressure plate 2. The arcuate contact portion 127 is in sliding contact with the two overlapping portions 24 on both sides of the first through hole 21. This reduces friction during the swinging of the button 12, providing a better operating experience for the wall switch.

[0075] Preferably, Figure 1As shown, the contact assembly 3 is installed in the mounting slot 41, and the pressure plate 2 is snap-fitted to the mounting bracket 4, limiting the contact assembly 3. The mounting slot 41 of the mounting bracket 4 includes a contact assembly mounting slot, and the contact assembly 3 is located in the contact assembly mounting slot. The pressure plate 2 includes at least one snap-fit ​​plate 25 extending toward the mounting bracket 4. The snap-fit ​​plate 25 includes a third snap, and the mounting bracket 4 includes at least one fourth snap that engages with the third snap. The third and fourth snaps are used to achieve snap-fit ​​installation of the pressure plate 2 and the mounting bracket 4.

[0076] Preferably, Figure 1 and Figure 6 As shown, the panel 5 is rotatably engaged with the mounting bracket 4. The side of the panel 5 facing the mounting bracket 4 includes at least one fifth latch 52, and the mounting bracket 4 includes at least one sixth latch 43. The at least one fifth latch 52 and the at least one sixth latch 43 are engaged in a one-to-one correspondence. The fifth latch 52 includes two arms, with a bayonet formed between the two arms. The sixth latch 43 includes a shaft located below the upper surface of the mounting plate and avoidance holes or avoidance grooves located on both sides of the shaft. The bayonet is rotatably engaged with the shaft, and the two arms extend into the two avoidance holes or avoidance grooves respectively. The shaft is located below the upper surface of the mounting plate, and the position of the shaft is lowered through the avoidance groove or avoidance hole to reduce the distance between the panel 5 and the mounting plate, thereby reducing the thickness of the wall switch.

[0077] Further, such as Figure 6 As shown, the mounting bracket 4 includes two sixth clips 43, which are located on both sides of the mounting groove 41 along the second direction, are located in the same straight line as the two mounting holes 42, and are located outside the two mounting holes 42. Correspondingly, the panel 5 includes two fifth clips 52.

[0078] Preferably, a silicone pad is provided in the mounting hole 42 , and the silicone pad can perform dust-proof and insulating treatment on the mounting hole 42 .

[0079] Preferably, Figure 1 and Figure 2 As shown, the contact assembly 3 of this embodiment includes three wiring terminals (a first wiring terminal 311, a second wiring terminal 312 and a third wiring terminal 313), a moving contact 32, a support plate 33 and two static contacts 34. The two static contacts 34 are located above the moving contact 32 along the thickness direction of the wall switch. The two ends of the moving contact 32 include two moving contacts, and the static contact 34 includes a static contact. The two static contacts 34 are fixedly connected to the first wiring terminal 311 and the second wiring terminal 312 respectively. The support plate 33 is connected to the third wiring terminal 313 and is vertically supported inside the mounting frame 4, as shown. Figure 7As shown, the end of the support plate 33 that contacts the movable contact 32 is bent to form an arcuate surface 341. The middle portion of the movable contact 32 is supported on the arcuate surface 341 for seesaw motion. The movable contact 32 and the stationary contact 34 are preferably made of copper, but aluminum, iron, or other conductive alloy materials are also acceptable.

[0080] Further, such as Figure 1 and Figure 2 As shown, the middle portion of the movable contact 32 includes a recessed area 35, and the push rod 13 at least partially extends into the recessed area 35. The panel 5 swings, causing the push rod 13 to swing left and right within the recessed area 35, driving the movable contact 32 to perform a seesaw motion with the arc-shaped surface 341 as a fulcrum, causing one end of the movable contact 32 to move upward and the other end to move downward. One end of the movable contact 32 contacts the corresponding static contact 34, and the other end disconnects from the corresponding static contact 34, thereby achieving circuit connection and disconnection. Of course, as another embodiment, the contact assembly 3 can also be provided with only one static contact 34.

[0081] Preferably, the static contact 34 includes a plug leg and a contact arm connected at a right angle. The plug legs of the two static contacts 34 are respectively inserted into the first terminal 311 and the second terminal 312 and are relatively parallel. The contact arm is parallel to the bottom surface of the mounting frame 4 and the ends of the contact arms of the two static contacts 34 away from the plug legs are opposite to each other.

[0082] A first support column is provided within the contact assembly mounting slot. The side of the pressure plate 2 facing the mounting bracket 4 includes at least two downward pressure columns. The first support column is positioned between the two downward pressure columns and compresses the contact arm relative to the wall switch along its thickness. This design provides a more stable mounting structure for the stationary contact 34.

[0083] Preferably, Figure 8 As shown, the wall switch also includes a slide plate 6 arranged between the panel 5 and the button 12, the panel 5 and the slide plate 6 are driven to cooperate, the slide plate 6 is connected to the button 12, and the sliding direction of the slide plate 6 is set along the first direction or at an angle to the first direction; the slide plate 6 can rotate and slide under the drive of the panel 5 to switch between the first position and the second position and drive the button 12 to rotate, so that the button 12 can drive the moving contact 32 to move to switch the state of the contact assembly 3.

[0084] Preferably, Figure 8As shown, in this embodiment, a linkage structure is provided between the slide plate 6 and the button 12. The slide plate 6 includes a first driving arm 210 and a second driving arm 220 spaced apart along a first direction. A first driving groove and a second driving groove are provided on both sides of the middle portion of the button 12. The first driving groove and the second driving groove enable the linkage plate 121 to form a first passive plate 402 and a second passive plate 403 on both sides along the first direction. The first driving arm 210 is driven and cooperated with the first passive plate 402, and the second driving arm 220 is driven and cooperated with the second passive plate 403.

[0085] The slide 6 can rotate and slide under the drive of the panel 5 to switch between the first position and the second position. At the same time, the slide 6 drives the first passive plate 402 through the first driving arm 210 or drives the second passive plate 403 through the second driving arm 220 to drive the button 12 to rotate, so that the button assembly 1 drives the moving contact 32 to contact or separate from the static contact 34. Specifically, when the slide 6 slides and rotates from the second position to the first position, the first driving arm 210 drives the first passive plate 402 to swing the button 12 toward the side close to the first driving arm 210, and the button 12 drives the moving contact 32 to contact with one static contact 34 and separate from the other static contact 34; when the slide 6 slides and rotates from the first position to the second position, the second driving arm 220 drives the second passive plate 403 to swing the button 12 toward the side close to the second driving arm 220, and the button 12 drives the moving contact 32 to separate from one static contact 34 and contact with the other static contact 34.

[0086] A slide plate 6 is added between the panel 5 and the button 12. The panel 5 drives the slide plate 6 to rotate and slide, and the slide plate 6 drives the button assembly 1 to swing at a large angle, and then the button assembly 1 drives the moving contact 32 to contact or separate with the static contact 34. Only one component is added, and the thickness of the switch is reduced. At the same time, the side of the slide plate 6 facing the mounting frame 4 also includes two driving arms, and the button 12 includes two driven plates. The two driven plates of the button 12 are driven by the two driving arms of the slide plate 6 to indirectly drive the button 12 to swing, so that the slide plate 6 slides with less displacement, and the panel 5 swings at a smaller angle, further realizing a larger swing of the button 12, and then realizing the connection and disconnection of the switch, reducing the swing angle of the wall switch, making the wall switch appear thinner, and improving the overall aesthetics. It is simple to assemble, low cost, easy to implement and has stable performance.

[0087] Furthermore, the first driving arm 210 protrudes toward the first passive plate 402 and extends into the first driving slot, while the second driving arm 220 protrudes toward the second passive plate 403 and extends into the second driving slot. This not only increases the swing angle of the button 12, but also does not increase the thickness of the switch, thereby enhancing the aesthetics of the switch. For example, the swing angle of the button 12 may be greater than 4 degrees, while the swing angle of the panel 5 may only be 2 degrees or less.

[0088] like Figure 8 As shown, the slide 6 of this embodiment is configured to slide with the mounting frame 4. The slide 6 is provided with a first sliding protrusion 205 and a second sliding protrusion 206 on both sides of the slide 6 facing the mounting frame 4. The first and second sliding protrusions 205, 206 are spaced relative to each other along a first direction. The mounting frame 4 is provided with a first guide bevel 207 that slidably engages with the first sliding protrusion 205 and a second guide bevel 208 that slidably engages with the second sliding protrusion 206. The first and second guide bevels 207, 208 are each arranged at an angle relative to the first direction. As the slide 6 rotates with the panel 5, the first sliding protrusion 205 acts on the first guide bevel 207, or the second sliding protrusion 206 acts on the second guide bevel 208, controlling the slide 6 to rotate and slide along the guide bevels on the mounting frame 4. Since the sliding distance of the slide 6 is controlled by the angle of the guide bevels on the mounting frame 4, the sliding distance of the slide 6 is more precisely controlled, thereby better controlling the swing angle of the button assembly 1 and the movement of the movable contact 32.

[0089] In this embodiment, the panel 5 rotates synchronously with the skateboard 6, and the skateboard 6 can slide relative to the panel 5 and the mounting frame 4 under the drive of the first guide slope 207 or the second guide slope 208 of the mounting frame 4. The panel 5 applies a rotational force to the skateboard 6, and the first guide slope 207 or the second guide slope 208 applies a sliding force to the skateboard 6.
