[0050] In the description of the present invention, the terms "inside", "outside", "horizontal", "vertical", "up", "down", "top", "bottom", "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0051] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features.

[0052] In the description of this utility model, unless otherwise specified or limited, the term "connection" and other terms should be understood in a broad sense. For example, it can mean fixed connection, detachable connection, or integration; it can mean mechanical connection, electrical connection, or mutual communication; it can mean direct connection or indirect connection through an intermediate medium; it can mean internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0053] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0054] In the prior art, wireless switches with displays generally rigidly limit the display screen between the movable part and the panel. The receiving groove between the movable part and the pressing panel is used to accommodate the display screen. However, due to manufacturing errors, the depth of the receiving groove cannot usually be accurately controlled, resulting in some installation problems. For example, if the depth of the receiving groove is too shallow, the panel will be lifted up by the display screen, and the panel and the movable part will not fit together, affecting the stability of the adhesion. In addition, the pressing force of the panel will be transmitted to the movable part through the display screen, causing the display screen to be easily crushed. For another example, if the depth of the limiting groove is too deep, the display screen will not fit together with the panel, the display screen will be unstable and the display effect will be poor. In short, the depth error of the receiving groove will lead to many adverse effects, thereby affecting the quality of the product.

[0055] Based on this, according to a first aspect of the present invention, a wireless switch 100 is provided, which is dedicated to reducing the impact of the dimensional error of the receiving groove on the positioning of the display screen.

[0056] See also Figures 1-21 , the wireless switch 100 provided by the present invention will be specifically explained. Figure 3 and Figure 7 As shown, the wireless switch 100 includes a bottom shell 5 , a button housing 1 , a circuit board 2 , a display screen 3 and an electronic switch 21 .

[0057] The key housing 1 is movably connected to the bottom housing 5; the circuit board 2 is mounted on the back of the key housing 1. The display screen 3 is limited in position by the circuit board 2 and the key housing 1. The key housing 1 is provided with a display window 11 at a position corresponding to the display screen 3. The electronic switch 21 is provided on the side of the circuit board 2 facing the bottom housing 5. When the key housing 1 moves relative to the bottom housing 5 in response to a pressing force, the circuit board 2, display screen 3, and electronic switch 21 move integrally with the key housing 1. During this movement, the electronic switch 21 presses against the bottom housing 5, causing it to be triggered.

[0058] The integrated movement can be understood as that during the movement of the button housing 1 , the display screen 3 , the circuit board 2 and the electronic switch 21 all move synchronously therewith.

[0059] The movable connection can be understood as a connection method that can generate relative motion, such as a pivot connection, a sliding connection, a ball joint connection, etc. In one embodiment, the key housing 1 is pivotally connected to the bottom housing 5, and the key housing 1 pivots based on the bottom housing 5 in response to a pressing force.

[0060] The display window 11 can be a through-hole or a transparent area, and the display content of the display screen 3 is displayed externally through the display window 11. The display screen 3 is restrained by the circuit board 2 and the key housing 1. This means that the circuit board 2 and the key housing 1 can directly abut against the upper and lower surfaces of the display screen 3 to clamp and restrain the display screen 3, or they can indirectly abut against the upper and lower surfaces of the display screen 3 through other components to restrain the display screen 3. In one specific example, the circuit board 2 abuts against the lower surface of the display screen 3 via the signal transmission member 22 and the filler member 23.

[0061] In this embodiment of the utility model, the display screen 3 is limited by the circuit board 2 and the key housing 1, reducing the number of parts. In addition, the key housing 1 is pivotally connected to the bottom shell 5, eliminating the need for multiple elastic support members to suspend the key housing 1, further reducing the number of parts. It is worth mentioning that the display screen 3 and the circuit board 2 move integrally with the key housing 1. When the key housing 1 is pressed, the weight of the display screen 3 and the circuit board 2 acts on the key housing 1, increasing the inertia of the key housing 1, making the pressing feel of the key housing 1 more substantial and providing a more textured pressing experience.

[0062] Furthermore, if Figure 8 and Figure 12-15 As shown, Figure 12-15This is the viewing angle of the wireless switch 100 after being flipped upside down. An isolation structure 12 is provided on the back of the button housing 1. The isolation structure 12 protrudes from the lower surface of the display screen 3 and abuts the circuit board 2, isolating the circuit board 2 and the display screen 3 by a predetermined distance. When the button housing 1 is pressed, the pressing force is transmitted to the circuit board 2 through the isolation structure 12, and then to the electronic switch 21 through the circuit board 2, causing the electronic switch 21 to press against the bottom housing 5. The predetermined distance between the circuit board 2 and the display screen 3 prevents the pressing force from being transmitted through the display screen 3, thus preventing damage to the display screen 3. At the same time, the isolation structure 12 rigidly supports the circuit board 2, making the circuit board 2 more stable.

[0063] In addition, in this embodiment, Figure 7 and Figure 16 As shown, an elastic signal transmission member 22 and an elastic filling member 23 are provided between the circuit board 2 and the display screen 3. The signal transmission member 22 is provided at the end of the display screen 3. The display screen 3 is connected to the circuit board 2 through the signal transmission member 22. The elastic force of the filling member 23 acts on the display screen 3 so that the display screen 3 and the key housing 1 remain in contact. The signal transmission member 22 can be conductive rubber, metal shrapnel or other elastic materials with conductive properties. When the circuit board 2 is locked to the key housing 1, the signal transmission member 22 is squeezed by the circuit board 2 and the display screen 3, so that the conduction between the display screen 3, the signal transmission member 22 and the circuit board 2 is stable. The filling member 23 is elastic and can be, for example, foam, rubber, silicone or made of other elastic materials.

[0064] To sum up, compared with the rigid limitation of the display screen in the prior art, this embodiment uses an elastic signal transmission component 22 and an elastic filling component 23 to provide an elastic limiting force, which not only makes the display screen 3 stably limited between the circuit board 2 and the button housing 1, but also ensures stable conduction between the display screen 3 and the circuit board 2.

[0065] In addition, the elastic signal transmission member 22 and the elastic filling member 23 cooperate with the isolation structure 12 to not only provide stable support for the circuit board 2 but also effectively prevent the display screen 3 from being crushed.

[0066] Furthermore, if Figure 15 As shown, the isolation structure 12 abuts against the side of the display screen 3 to position the display screen 3 circumferentially, so that the display screen 3 is limited to the inner side of the isolation structure 12 without the need to set other limiting structures.

[0067] Furthermore, the isolation structure 12 includes a plurality of isolation walls 121 arranged around the display screen 3, and positioning ribs 122 arranged on the isolation walls 121, the positioning ribs 122 abut against the side of the display screen 3 to limit the horizontal freedom of the display screen 3, the signal transmission component 22 and the filling component 23 abut against the lower surface of the display screen 3, and the button housing 1 abuts against the upper surface of the display screen 3 to limit the vertical freedom of the display screen 3, thereby limiting all the degrees of freedom of the display screen 3, without the need to set up other additional limiting structures to limit the display screen 3.

[0068] In some embodiments, as Figure 16 As shown, the signal transmission member 22 is a conductive rubber strip, and the filler 23 is a strip-shaped structure. The filler 23 is located at the end of the display screen 3 away from the signal transmission member 22. The filler 23 and the signal transmission member 22 are arranged side by side to stably support the display screen 3, so that the display screen 3 and the key housing 1 are in good contact. The side by side arrangement can be understood as a parallel arrangement or an angle between the two being less than 30 degrees.

[0069] In this embodiment, the signal transmission member 22 and the filling member 23 are arranged in parallel at both ends of the display screen 3. Furthermore, the filling member 23 is adhered to the circuit board 2.

[0070] Furthermore, if Figure 16 As shown, the conductive adhesive strip is a three-layer structure, including a conductive layer 221 located in the center and insulating layers 222 located on both sides of the conductive layer 221. The insulating layers 222 are attached to the conductive layer 221. The display screen 3 is provided with a first conductive portion 31 at a position corresponding to the conductive adhesive strip. The first conductive portion 31 is composed of a plurality of conductive contacts arranged as shown in FIG. Figure 17 As shown, the circuit board 2 is provided with a second conductive portion 24 at a position corresponding to the conductive rubber strip. The second conductive portion 24 is composed of a plurality of metal contacts arranged. The metal contacts are connected to the conductive contacts through the conductive rubber strip to realize signal transmission between the display screen 3 and the circuit board 2.

[0071] In some embodiments, as Figure 10 and Figure 12As shown, the end of the circuit board 2 away from the signal transmission member 22 is clamped to the button housing 1, and the end of the circuit board 2 close to the signal transmission member 22 is locked to the button housing 1 by a locking member 25. Under the locking action of the locking member 25, the circuit board 2 squeezes the signal transmission member 22, so that the connection between the circuit board 2, the signal transmission member 22 and the display screen 3 is stable to ensure stable signal transmission. In addition, one end of the circuit board 2 is clamped to the button housing 1, and the other end is locked with the locking member 25 to improve assembly efficiency. Among them, the locking member 25 can be understood as a part that can lock the circuit board 2 to the button housing 1, such as a screw, a rotating lock or a press lock.

[0072] Furthermore, if Figure 13 As shown, the locking members 25 are configured as two connecting screws. The button housing 1 is provided with connecting posts 13 at positions corresponding to the connecting screws. The circuit board 2 has positioning openings 251 at positions corresponding to the connecting posts 13. The positioning openings 251 mate with the connecting posts 13, and the connecting screws lock onto the connecting posts 13, thereby locking the circuit board 2 to the button housing 1. The connecting posts 13 not only position the circuit board 2 but also secure it, making the structure more compact. The connecting posts 13 extend from the button housing 1 toward the circuit board 2. The ends of the connecting posts 13 have threaded holes adapted for the connecting screws. The two connecting posts 13 are arranged parallel to the extension direction of the conductive rubber strip. The connecting posts 13 are located at the edge of the circuit board 2. The positioning openings 251 of the circuit board 2 are semicircular, with a diameter adapted to that of the connecting posts 13. When the circuit board 2 is installed in the button housing 1, the connecting posts 13 fit into the positioning openings 251, ensuring proper positioning between the two. The height of the connecting pillar 13 is adapted to the thickness of the circuit board 2 , so that when the connecting screw is tightened on the connecting pillar 13 , the circuit board 2 can be locked to the key housing 1 .

[0073] Furthermore, if Figure 12 As shown, the button housing 1 is provided with two first latches 14 at one end away from the signal transmission member 22. The first latches 14 are used to latch onto the circuit board 2. The circuit board 2 is provided with a positioning portion 26 between the two first latches 14. The width of the positioning portion 26 is adapted to the spacing between the two first latches 14, so that the positioning portion 26 is positioned between the two first latches 14. The first latches 14 extend downward from the top wall of the button housing 1, and the arrangement direction of the two first latches 14 is parallel to the extension direction of the conductive rubber strip. Furthermore, the positioning portion 26 is integrally formed with the circuit board 2.

[0074] The button housing 1 of this embodiment uses the connecting column 13 and the first clip 14 to position the two ends of the circuit board 2, without setting up a special positioning structure to position the circuit board 2, thereby ensuring the relative position accuracy between the circuit board 2 and the button housing 1.

[0075] Furthermore, if Figure 7 and Figure 3 As shown, the bottom shell 5 has a third end close to the signal transmission member 22 and a fourth end away from the signal transmission member 22. The pivot shaft 511 of the pivotal connection is arranged in the area of ​​the bottom shell 5 close to the third end, so that the pivot shaft 511 is close to the signal transmission member 22, thereby allowing the signal transmission member 22 to have a smaller movement amplitude during the key pressing process, thereby ensuring stable signal transmission. The area close to the third end can be understood as the area near the third end. The pivot connection can be a shaft-hole connection, a rotatable clamping connection or other connection methods that can pivot. The pivot shaft 511 can be understood as the rotation center axis of the pivot connection, or can also be understood as a physical axis. In a specific embodiment, as Figure 4 As shown, the pivot shaft 511 is a convex shaft.

[0076] The circuit board 2 has a first end near the pivot axis 511 and a second end away from the pivot axis 511. The electronic switch 21 is disposed in an area of ​​the circuit board 2 near the second end. According to the principle of leverage, the closer the electronic switch 21 is to the second end, the shorter the pressing stroke of the key housing 1 required to trigger the electronic switch 21. Shortening the movable stroke of the key housing 1 reduces the space reserved at the bottom of the key housing 1, allowing the side of the key housing 1 to cover more of the bottom shell 5, thereby improving the overall appearance of the wireless switch 100. The area near the second end can be understood as the area near the second end.

[0077] Furthermore, if Figure 4 As shown, the bottom shell 5 is provided with two pivot arms 51 extending from the area near the third end. The two pivot arms 51 are respectively located on both sides of the bottom shell 5. The ends of the two pivot arms 51 are respectively provided with the pivot shafts 511 protruding therefrom. The two pivot shafts 511 are arranged opposite to each other. Figure 11 and Figure 12 The key housing 1 is pivotally connected to the bottom housing 5 by an axial-hole connection. The key housing 1 is provided with connecting plates 15 on the inner sides of the two pivot arms 51. The connecting plates 15 are provided with pivot holes 151. The pivot shaft 511 is inserted into the pivot hole 151. The pivot shaft 511 can rotate in the pivot hole 151.

[0078] Furthermore, if Figure 12 and Figure 10As shown, the first buckle 14 defines a buckle hole 141, and the bottom shell 5 is provided with a second buckle 52 at a position corresponding to the buckle hole 141. The second buckle 52 buckles with the buckle hole 141, that is, the second buckle 52 buckles with the first buckle 14, making the structure more compact and facilitating a reduction in the thickness of the wireless switch 100. Furthermore, the first buckle 14 includes a first arm extending from the button housing 1 and a first hook disposed at the end of the first arm. The first hook engages the circuit board 2, and the buckle hole 141 is defined in the first arm.

[0079] In some embodiments, as Figure 7 As shown, the triggering portion of the electronic switch 21 is elastic. When the pressing force is removed, the button housing 1, the display screen 3 and the circuit board 2 are reset under the elastic force of the electronic switch 21, so that the wireless switch 100 does not need to be equipped with a reset mechanism separately, thereby reducing the number of parts. At the same time, since the pressing resistance only comes from the elastic force of the electronic switch 21, the triggering feedback of the electronic switch 21 can be more clearly transmitted to the button housing 1, and the pressing feel is better. The triggering portion can be understood as the part where the electronic switch 21 is pressed. In a preferred embodiment, the electronic switch 21 is a touch switch, and the triggering portion of the touch switch is made of silicone. Furthermore, as Figure 3 and Figure 7 As shown, the bottom shell 5 is provided with a trigger protrusion 53 at a position corresponding to the trigger portion of the electronic switch 21. The trigger protrusion 53 is used to accurately trigger the trigger portion. Furthermore, when the button housing 1 is not pressed, the trigger protrusion 53 still presses against the trigger portion, keeping the trigger portion in a slightly compressed state. This allows the trigger portion to provide pre-tightening force when the button housing 1 is not pressed, preventing the button housing 1 from becoming loose.

[0080] In existing wireless switches with display screens, the panel is fixed to the movable part. Pressing the panel downward drives the movable part downward. The position of the middle shell is fixed, and the panel moves relative to the middle shell. A pressing gap must be reserved between the panel and the middle shell. This gap makes the wireless switch less dustproof and splashproof and destroys the integrity of the shell. To solve this problem, in this embodiment, Figure 1-Figure 5 As shown, in this embodiment, because the circuit board 2, display screen 3, and electronic switch 21 are all fixedly connected to the key housing 1, and no reset mechanism is required, the key housing 1 can cover a larger area of ​​the bottom shell 5, thereby improving the integrity of the housing and enhancing dust and water splash resistance. The key housing 1 includes a key top wall and a key side wall 16 extending downward from the periphery of the key top wall. The key housing 1 is covered by the bottom shell 5, and the key side wall 16 surrounds the bottom shell 5.

[0081] Furthermore, if Figure 7As shown, the button housing 1 is provided with the display window 11 at a position directly opposite to the display area of ​​the display screen 3. The display window 11 is constructed as a through hole that penetrates the button housing 1. Thanks to the elastic support force provided by the filling member 23 and the signal transmission member 22, the upper surface of the display screen 3 can be tightly attached to the inner wall of the button housing 1 to eliminate the gap between the display screen 3 and the display window 11, thereby improving the dustproof and water splashproof performance.

[0082] Furthermore, if Figure 2 As shown, a pressing mark 17 is provided on the upper surface of the button housing 1 at one end away from the display window 11. The pressing mark 17 is used to indicate the correct pressing area so that the user can more effortlessly trigger the electronic switch 21. The pressing mark 17 is constructed as an arc-shaped depression.

[0083] Furthermore, if Figure 7-Figure 8 As shown, Figure 7 for Figure 6 AA cross-sectional view, Figure 8 for Figure 7 In the enlarged view of the D part, a temperature and humidity sensor 27 is provided on the side of the circuit board 2 facing the bottom shell 5, and the detection result of the temperature and humidity sensor 27 is displayed on the display screen 3; the temperature and humidity sensor 27 is provided at the edge of the circuit board 2, and the temperature and humidity sensor 27 moves in response to the pivoting movement of the key shell 1. The temperature and humidity sensor 27 is provided at the edge of the circuit board 2, so that when the key shell 1 is pressed, the temperature and humidity sensor 27 moves up and down with a larger amplitude, which is conducive to improving the sensing accuracy of the temperature and humidity sensor 27. In addition, the temperature and humidity sensor 27 is provided on the lower surface of the circuit board 2. When the key shell 1 is pressed, the distance between the circuit board 2 and the bottom shell 5 changes, thereby disturbing the air flow between the circuit board 2 and the bottom shell 5, further improving the sensing accuracy of the temperature and humidity sensor.

[0084] like Figure 8 and Figure 3-Figure 5As shown, the button side wall 16 is provided with a first air vent 161 at a position corresponding to the temperature and humidity sensor 27, and the bottom shell 5 includes a bottom shell side wall, a bottom shell bottom wall, a first partition wall 541, a second partition wall 542 and a third partition wall 543. The bottom shell side wall, the bottom shell bottom wall, the first partition wall 541, the second partition wall 542 and the third partition wall 543 are mutually surrounded to form an air flow groove 544, and the circuit board 2 is covered in the air flow groove 544. The temperature and humidity sensor 27 is at least partially accommodated in the air flow groove 544; the bottom shell bottom wall is provided with a second air vent 545 at the position where the air flow groove 544 is located. In this embodiment, the air flow groove 544 is connected to the outside through the first air vent 161 and the second air vent 545. When the button housing 1 is pressed, the button housing 1 and the circuit board 2 move relative to the bottom shell 5, driving the external air into the air flow groove 544 through the first air vent 161 and / or the second air vent 545, thereby improving the accuracy of the temperature and humidity sensor 27 in detecting the ambient temperature and humidity. It is worth mentioning that the first air vent 161 and the second air vent 545 are respectively opened on the side and the bottom, which increases air circulation. In addition, the first partition wall 541, the second partition wall 542 and the third partition wall 543 can also reduce the impact of the heat generated by other electronic components on the accuracy of the temperature and humidity sensor 27.

[0085] In this embodiment, the air flow groove 544 is set on the bottom shell 5, and the air flow groove 544 always remains in a stationary state. When the button shell 1 moves, the circuit board 2 and the temperature and humidity sensor 27 produce relative movement relative to the air flow groove 544, thereby enhancing the air circulation in the air flow groove 544.

[0086] Furthermore, if Figure 7 and Figure 9 As shown, Figure 9 This is a simplified schematic diagram of the wireless switch 100 structure. The temperature and humidity sensor 27 generates a vertical motion component in response to the movement of the circuit board 2, allowing air near the temperature and humidity sensor 27 to circulate, thereby improving the accuracy of the temperature and humidity sensor 27 in detecting the ambient temperature and humidity.

[0087] like Figure 9As shown, the key housing 1 is pivotally connected to the bottom housing 5. The circuit board 2 includes a first end near the pivot axis 511 and a second end away from the pivot axis 511. The temperature and humidity sensor 27 is disposed at the first end of the circuit board 2, and the electronic switch 21 is disposed in an area near the second end of the circuit board 2. This avoids conflict between the installation positions of the electronic switch 21 and the temperature and humidity sensor 27, facilitating the placement of the electronic switch 21 and the temperature and humidity sensor 27 at the middle of the two ends of the circuit board 2. This improves the pressing feel of the key housing 1 and facilitates the arrangement of the airflow groove 544, the first air vent 161, and the second air vent 545. In addition, the electronic switch 21 and the temperature and humidity sensor 27 are respectively disposed on the left and right sides of the pivot axis 511. When the electronic switch 21 moves downward in response to a pressing force, the temperature and humidity sensor 27 tilts upward. When the electronic switch 21 is reset, the temperature and humidity sensor 27 returns to its initial position downward. The up and down movement of the electronic switch 21 can drive the up and down movement of the temperature and humidity sensor 27, thereby improving the detection accuracy of the temperature and humidity sensor 27.

[0088] Furthermore, the temperature and humidity sensor 27 and the electronic switch 21 are disposed on the same side of the circuit board 2, so that there is sufficient space on the side of the circuit board 2 opposite the electronic switch 21 to accommodate the display screen 3. Furthermore, the signal transmission element 22 and the temperature and humidity sensor 27 are disposed on the same end of the circuit board 2, but are disposed on the upper and lower surfaces of the circuit board 2.

[0089] Furthermore, if Figure 4 As shown, the first partition wall 541, the second partition wall 542 and the third partition wall 543 are integrally formed on the bottom shell 5, and the air flow groove 544 is constructed as a square groove body. Figure 5 As shown, the bottom wall of the bottom shell is provided with three small holes at the bottom of the air flow groove 544, and the three small holes form the second air holes 545. The first air holes 161 are constructed as long strip holes placed horizontally, such as Figure 8 As shown, the height of the first air hole 161 is slightly lower than the height of the temperature and humidity sensor 27 , which is conducive to the external air entering the air flow groove 544 from the first air hole 161 and quickly reaching the temperature and humidity sensor 27 .

[0090] Furthermore, if Figure 8 and Figure 4 As shown, the bottom shell sidewall has a communication opening 546 directly opposite the first vent hole 161. The communication opening 546 connects the first vent hole 161 with the air flow groove 544, facilitating unimpeded entry of external air into the air flow groove 544 from the first vent hole 161, thereby improving the accuracy of detection by the temperature and humidity sensor 27. Furthermore, the communication opening 546 is formed by a downward depression in the top of the bottom shell sidewall.

[0091] Furthermore, if Figure 9 As shown, the horizontal distance between the temperature and humidity sensor 27 and the pivot axis 511 is set to L1, and the horizontal distance between the electronic switch 21 and the pivot axis 511 is set to L2. If L1 / L2 is too small, the movement amplitude of the temperature and humidity sensor 27 during the pressing process of the key housing 1 is small, and the air circulation in the airflow groove 544 is slow, affecting the detection accuracy of the temperature and humidity sensor 27. If L1 / L2 is too large, when the right end of the key housing 1 is pressed, the left end of the key housing 1 tilts up significantly, resulting in a wide gap between the key housing 1 and the bottom shell 5, affecting the integrity of the housing. To this end, in this embodiment, L1 and L2 satisfy the relationship: 0.25≤L1 / L2≤0.7, so that the movement amplitude of the left end of the key housing 1 is within an appropriate range, while ensuring the detection accuracy of the temperature and humidity sensor 27, while avoiding an excessively large gap between the key housing 1 and the bottom shell 5.

[0092] Furthermore, if Figure 5 As shown, a double-sided tape 55 is provided on the side of the bottom shell 5 away from the button housing 1. The bottom shell 5 is mounted externally via the double-sided tape 55, and the second air vent 545 is not covered by the double-sided tape 55. Furthermore, the double-sided tape 55 is circular and affixed to the center of the bottom surface of the bottom shell 5. The lower surface of the double-sided tape 55 protrudes from the lower surface of the bottom shell 5, so that when the bottom shell 5 is affixed to the mounting surface, the second air vent 545 does not contact the mounting surface, thereby preventing the second air vent 545 from being blocked.

[0093] Furthermore, the display screen 3 is a continuous screen, and the circuit board 2 is provided with a button battery 4, which is used to power the circuit board 2. The button battery 4 is very small, which facilitates the miniaturization of the wireless switch 100. However, the button battery 4 generally has a low charge and poor battery life. Therefore, the display screen 3 uses a continuous screen, which has no backlight and is very energy-efficient, greatly improving the battery life of the button battery 4. In a specific embodiment, the button battery 4 is a CR2032 battery, and the continuous screen uses a 1.4-inch LCD continuous screen. The continuous screen displays information continuously and does not turn off the screen. When the continuous screen is working, the battery life can reach over one year.

[0094] Furthermore, the button battery 4 moves synchronously with the circuit board 2, which is equivalent to adding the weight of the button battery 4 to the key housing 1. Since the button battery 4 is heavy, the inertia of the key housing 1 is increased, so that the key housing 1 has a counterweight greater than its own weight during the pressing movement, making the pressing feel of the key housing 1 heavier, and allowing the key housing 1 made of plastic material to have a pressing texture similar to that of metal material.

[0095] Furthermore, the circuit board 2, display screen 3, button battery 4 and electronic switch 21 move integrally with the key housing 1, that is, the weight of the display screen 3, circuit board 2 and button battery 4 are all added to the key housing 1, further increasing the inertia of the key housing 1, making the pressing feel of the key housing 1 heavier.

[0096] Furthermore, if Figure 3 As shown, the button battery 4 is arranged on the side of the circuit board 2 facing the bottom shell 5 to facilitate battery replacement. Specifically, one end of the bottom shell 5 is connected to the button shell 1 through the pivot shaft 511, and the other end is clamped to the button shell 1 through the second clip 52. The end of the bottom shell 5 close to the second clip 52 is provided with a handle 57. The handle 57 is recessed in the side of the bottom shell 5, and a force step is provided at the bottom of the handle 57. When the button shell 1 is buckled into the bottom shell 5, the force step at the bottom of the handle 57 is exposed under the button shell 1. The user can use a fingernail to push the force step downward to disengage the second clip 52 from the button shell 1, and then pry the bottom shell 5 downward to disengage the pivot shaft 511 from the pivot hole 151, thereby removing the bottom shell 5 from the button shell 1.

[0097] like Figure 4 and Figure 11 As shown, the pivot shaft 511 is provided at the end of the pivot arm 51. The pivot shaft 511 is constructed as a short convex shaft, and the end of the pivot shaft 511 is provided with a rounded corner to facilitate the pivot shaft 511 to be inserted into / disengaged from the pivot hole 151. At the same time, the pivot arm 51 of the bottom shell 5 is long and easy to deform, which further facilitates the pivot shaft 511 to be inserted into / disengaged from the pivot hole 151, thereby facilitating the detachment of the bottom shell 5 from the key housing 1. It is worth noting that there is no need to worry about the pivot shaft 511 being separated from the pivot hole 151 during normal use, because the key housing 1 is generally under pressure during normal use, such as Figure 11 As shown, the top of the pivot arm 51 abuts against the inner wall of the key housing 1 to support the key housing 1 when it is pressed, preventing the pivot shaft 511 from falling downward from the pivot hole 151. In addition, the bottom housing 5 does not have a finger-like structure at the end near the pivot shaft 511, making it difficult for the user to pry this end open during normal use, thereby preventing the pivot shaft 511 from falling out of the pivot hole 151 during normal use.

[0098] Furthermore, if Figure 14 As shown, the circuit board 2 is provided with a conductive clamping member 28, and the button battery 4 is clamped and limited by the conductive clamping member 28. The button battery 4 is electrically connected to the circuit board 2 through the conductive clamping member 28. The button battery 4 is limited by the conductive clamping member 28, which avoids the need to provide other limiting structures on the key housing 1 to limit the button battery 4.

[0099] Furthermore, if Figure 14 and Figure 13 As shown, it should be noted that Figure 13 and Figure 14 The perspective is the perspective after the wireless switch 100 is turned upside down. The conductive clamping member 28 includes a horizontally arranged conductive clamping wall 281 and conductive side walls 282 extending on both sides of the conductive clamping wall 281. The conductive side walls 282 are welded to the circuit board 2; the button battery 4 is clamped between the conductive clamping wall 281 and the circuit board 2. Figure 14 In the figure, the lower surface of the button battery 4 is the negative electrode, and the side and upper surfaces are the positive electrode. The circuit board 2 is provided with a conductive area (not shown) at the position corresponding to the button battery 4. The lower surface of the button battery 4 abuts the conductive area, and the upper surface of the button battery 4 abuts the conductive clamping wall 281. The circuit board 2 is provided with a large circular pad in the conductive area. The negative electrode of the button battery 4 abuts the circular pad to conduct electricity to the circuit board 2. Furthermore, the conductive clamping member 28 is formed by cutting and bending a metal sheet.

[0100] Furthermore, the conductive clamping wall 281 is cut to form two inclined clamping arms 283, and the clamping arms 283 are inclined toward the button battery 4. When the button battery 4 is loaded into the conductive clamping member 28, the button battery 4 squeezes the clamping arms 283 to cause elastic deformation, which not only enhances the conductive stability, but also increases the clamping force of the clamping arms 283 to clamp the button battery 4, thereby preventing the button battery 4 from falling out.

[0101] Furthermore, if Figure 14 and Figure 13 As shown, the conductive clamp 28 has an insertion end and a limiting end. The insertion end is open, allowing the button battery 4 to be loaded horizontally into the conductive clamp 28 from the insertion end. The conductive clamp 28 is provided with two vertical limiting blocks 284 at the limiting end. The limiting blocks 284 are bent around the conductive clamping wall 281 and are located on either side of the button battery 4, inclined in the direction of insertion. The limiting blocks 284 not only prevent the button battery 4 from escaping, but also indicate the correct installation position. That is, when the button battery 4 abuts the limiting blocks 284, it indicates that the button battery 4 is properly installed.

[0102] Furthermore, if Figure 17 and Figure 18 As shown, the circuit board 2 is provided with a wireless communication module 291, and the wireless communication module 291 is electrically connected to an on-board antenna 292. The on-board antenna 292 and the button battery 4 are respectively located on two sides of the circuit board 2, and the on-board antenna 292 is arranged at the end of the circuit board 2 away from the button battery 4; the on-board antenna 292 is laid on the circuit board 2 in a winding manner using a metal strip. Figure 18 The display screen 3 is projected on the circuit board 2 to form a first projection pattern (the first projection pattern is in Figure 18 (marked with a thick line in the figure), the onboard antenna 292 is at least partially located outside the first projection pattern to prevent the signal of the onboard antenna 292 from being shielded by the display screen 3. Furthermore, at least 80% of the area of ​​the onboard antenna 292 is located outside the first projection pattern.

[0103] Furthermore, if Figure 19 As shown in FIG. 2 , it is a schematic diagram of the structure of the onboard antenna 292. Figure 19 Marked with a thick solid line. The onboard antenna 292 includes a grounding strip and a feeding strip extending in the vertical direction. The upper end of the grounding strip is grounded, the upper end of the feeding strip is electrically connected to the wireless communication module 291, and the lower end of the grounding strip is connected to the lower end of the feeding strip. The grounding strip is spaced apart on the left side of the feeding strip, and the distance D1 between the grounding strip and the feeding strip is 1.4 mm. A bending strip extends to the right from the lower end of the feeding strip. The bending strip first extends to the right and then bends upward to form two "J"-shaped ridges, and the tail end of the bending strip is tilted upward. The feeding strip, the grounding strip and the bending strip are formed as one piece. The width W2 of the grounding strip is 0.9mm, the width W1 of the collapse strip is 0.5mm, the width of the bending strip is 0.5mm, the spacing D2 between the collapse strip and the "J"-shaped protrusion is 1.7mm, the spacing D3 between the two "J"-shaped protrusions is 1.7mm, the width L6 of the "J"-shaped protrusion is 3mm, the vertical width L4 of the bending strip is 3.14mm, and the spacing D4 between the raised part of the tail end of the bending strip and the "J"-shaped protrusion is 1.7mm. Among them, the researchers controlled the sum of the lengths of the collapse strip and the bending strip by controlling the raised height L5 of the tail end of the bending strip, so that the impedance of the onboard antenna 292 is consistent with the chip output internal resistance of the wireless communication module 291, so that the onboard antenna 292 can obtain greater power to improve signal strength and communication distance. In a specific example, the tilting height L5 is 0.44 mm, and the sum of the lengths of the broken strip and the bending strip is 28 mm, so that the impedance of the onboard antenna 292 is matched to 50 Ω. Figure 19 The length of the neutral wire.

[0104] Furthermore, if Figure 17 As shown, the wireless communication module 291 integrates a processing module that detects whether the electronic switch 21 is triggered, generates a corresponding control signal, and then transmits the control signal to trigger the corresponding controlled device. The processing module may include, for example, a single-chip microcomputer, which processes the electrical signal transmitted by the electronic switch 21 and communicates externally via the Bluetooth module.

[0105] The wireless communication module 291 is arranged between the display screen 3 and the circuit board 2. A driving chip 293 is arranged at one end of the circuit board 2 away from the display screen 3. The driving chip 293 is used to drive the display screen 3. The driving chip 293 is arranged outside the first projection pattern. Figure 7 As shown, the driver chip 293 and the electronic switch 21 are arranged on both sides of the circuit board 2 and located at the same end to improve the space utilization inside the key housing 1. Furthermore, some pins of the driver chip 293 are soldered to the positioning portion 26 of the circuit board 2 to save space on the circuit board 2.

[0106] In another embodiment of the present invention, Figure 20 and Figure 21 As shown, a wireless switch is also provided. Compared with the structural solution provided in the previously described embodiment, the focus of this embodiment is on the disassembly method of the bottom shell 5, especially focusing on the safety hazard caused by the button battery 4 being easily pulled out due to the overly simple disassembly method.

[0107] This embodiment can be considered not only an extension and enrichment of the previous embodiments, but can also be used to improve upon or integrate them to create a more comprehensive and flexible wireless switch implementation. Of course, the wireless switch of this embodiment can also be implemented independently, without relying on other embodiments. Structural features and operational mechanisms shared with previous embodiments will not be detailed in this embodiment to avoid repetition. Instead, this embodiment focuses on revealing its unique features.

[0108] Specifically, this embodiment and Figures 1-19 The difference between the embodiments is that the bottom shell 5 is provided with a locking portion 58 at one end away from the pivot connection. The locking portion 58 includes a locking protrusion 581 and an unlocking protrusion 582. When the bottom shell 5 is engaged with the button housing 1, the locking protrusion 581 is engaged with the button housing 1, and the unlocking protrusion 582 is not blocked by the button side wall 16. The unlocking protrusion 582 can be pressed to drive the locking protrusion 581 out of engagement, and the unlocking protrusion 582 can drive the locking protrusion 581 back into engagement when the pressure is released. In this embodiment, the locking protrusion 581 restricts the bottom shell 5 from being separated from the button housing 1. The user needs to press the unlocking protrusion 582 while pulling the bottom shell 5 downward to detach the bottom shell 5 from the button housing 1. This makes it easier to remove the bottom shell 5, prevents the button battery 4 from being pulled out by children, and eliminates safety hazards.

[0109] Furthermore, if Figure 20 and Figure 21As shown, the locking portion 58 further includes a support arm 583 and an elastic arm 584. The bottom of the support arm 583 is connected to the bottom shell 5, and the top of the support arm 583 is connected to the top of the elastic arm 584. The locking protrusion 581 and the unlocking protrusion 582 are arranged from top to bottom on the elastic arm 584. When the unlocking protrusion 582 is pressed, the elastic arm 584 is deformed, and the elastic arm 584 drives the locking protrusion 581 to produce a horizontal displacement, so that the locking protrusion 581 is disengaged from the key housing 1, thereby allowing the bottom shell 5 to be detached from the key housing 1. There are two support arms 583, one on each side of the elastic arm 584, and the top of each support arm 583 is connected to the top of each elastic arm 584. The two support arms 583 and the elastic arm 584 are configured to appear similar to the capital letter "M" from a certain angle to enhance the deformation ability of the elastic arm 584. The support arm 583 , the elastic arm 584 , the locking protrusion 581 , the unlocking protrusion 582 and the bottom shell 5 are integrally formed.

[0110] An operation notch 162 is provided at the bottom of the button side wall 16 at a position corresponding to the unlocking protrusion 582 . The operation notch 162 exposes the unlocking protrusion 582 , making it easier for a user to press the unlocking protrusion 582 .

[0111] The button side wall 16 is provided with a third clip 163 protruding inward and adapted to the locking protrusion 581 . The locking protrusion 581 is engaged with the third clip 163 to prevent the bottom shell 5 from being separated from the button housing 1 .

[0112] Furthermore, the support arm 583 also has elastic deformation capability to ensure that the locking protrusion 581 can be smoothly separated from the third buckle 163.

[0113] Furthermore, if Figure 21 As shown, compared to Figures 1-19 In the embodiment shown, there is a gap between the right end of the circuit board 2 and the side wall of the bottom shell 5 to provide space for the elastic arm 584 and the support arm 583 to deform to the left, so that the locking protrusion 581 can be displaced to the left and thus smoothly disengage from the third clip 163.

[0114] Furthermore, if Figure 20 As shown, the pivot arm 51 and the second clip 52 are both provided with reinforcing ribs to enhance the strength and rigidity of the pivot arm 51 and the second clip 52. Furthermore, the upper corners of the airflow slot 544 are provided with avoidance notches to avoid interference with the electronic components on the circuit board 2.

[0115] In addition, to solve the problem that the button battery 4 is easily pulled out by children, another embodiment of the present invention further provides a wireless switch. Similar to the above embodiment, this embodiment focuses on revealing the uniqueness of this embodiment. For those structural features and operating mechanisms shared with the previous embodiments, this embodiment will not be repeated to avoid repetition.

[0116] Specific as Figure 22 As shown, this embodiment is Figures 1-19 The difference between the embodiment shown is that the conductive clamping member 28 used in this embodiment can prevent the button battery 4 from falling out. Figure 22 As shown, the conductive clamping member 28 provided in this embodiment is Figures 1-19 The conductive clamping member 28 of the embodiment differs in that it is provided with a limit spring 285 at the insertion end. When the button battery 4 is inserted into the conductive clamping member 28, the limit spring 285 engages the side of the button battery 4 to prevent the button battery 4 from being separated from the conductive clamping member 28 at the insertion end. This prevents the button battery 4 from accidentally falling out and makes battery removal easier, preventing the button battery 4 from being easily removed and posing a safety hazard to children.

[0117] Furthermore, if Figure 22 As shown, the limiting spring piece 285 includes an elastic section extending from the conductive clamping wall 281 and a limiting hook provided at the end of the elastic section. The elastic section extends horizontally toward the loading end, and the limiting hook is bent vertically downward relative to the elastic section. When the button battery is loaded into the conductive clamping member 28, the limiting hook is connected to the side of the button battery 4 to prevent the button battery 4 from being detached. Furthermore, the elastic section is elastic. When the button battery 4 needs to be removed, two operations must be performed simultaneously to remove the button battery 4: the first operation is to bend the limiting spring piece 285 upward so that the height of the limiting hook is higher than the upper surface of the button battery 4, and the limiting effect of the limiting hook disappears. While performing the first operation, the second operation is performed. The second operation is to push the button battery 4 from the limiting end of the conductive clamping member 28 toward the loading end, thereby pushing the button battery 4 out of the conductive clamping member 28. In this embodiment, the first operation and the second operation need to be performed simultaneously, which further increases the difficulty of removing the button battery 4 and prevents the button battery 4 from being removed by children.

[0118] Furthermore, if Figure 22 As shown, an operating recess 2811 is provided at one end of the conductive clamping wall 281 facing the limit end. The operating recess 2811 is a horizontal arc-shaped recess. The function of the operating recess 2811 is to prevent the conductive clamping wall 281 from hindering the user from pushing out the button battery 4, so as to ensure that the user can push the button battery 4 out of the conductive clamping member 28.

[0119] In existing wireless switches with temperature and humidity sensors, the temperature and humidity sensors are always in a stationary state and do not move with the movement of the buttons. As a result, the air around the temperature and humidity sensors is stagnant, affecting the accuracy of the temperature and humidity sensors in detecting the ambient temperature and humidity.

[0120] In order to improve the detection accuracy of the temperature and humidity sensor, according to the second aspect of the present invention, a wireless switch 100 is provided. The technical details of the wireless switch 100 have been described in detail in the first aspect above. Figures 1-21 As shown, the wireless switch 100 includes a bottom housing 5, a key housing 1, a circuit board 2, and an electronic switch 21. The key housing 1 is movably connected to the bottom housing 5; the circuit board 2 is mounted on the back of the key housing 1; and the electronic switch 21 is located on the side of the circuit board 2 facing the bottom housing 5. When the key housing 1 moves relative to the bottom housing 5 in response to a pressing force, the circuit board 2 and the electronic switch 21 move integrally with the key housing 1. During this movement, the electronic switch 21 presses against the bottom housing 5, causing the electronic switch 21 to be triggered. The circuit board 2 is also provided with a temperature and humidity sensor 27. The temperature and humidity sensor 27 generates a vertical motion component in response to the movement of the circuit board 2, allowing air to circulate near the temperature and humidity sensor 27, thereby improving the accuracy of the temperature and humidity sensor 27 in detecting the ambient temperature and humidity. The temperature and humidity sensor 27 and the electronic switch 21 are located on the same side of the circuit board 2, leaving sufficient space on the other side of the circuit board 2 for the display screen 3 or other electronic components, which helps to reduce the size of the wireless switch 100. Among them, the technical details of the bottom shell 5, the button housing 1, the circuit board 2, the electronic switch 21 and the temperature and humidity sensor 27 have been recorded in detail above and will not be repeated here.

[0121] Furthermore, if Figure 8 and Figure 3-Figure 5 As shown, the bottom shell 5 is provided with an air flow groove 544 at a position corresponding to the temperature and humidity sensor 27, the circuit board 2 is covered in the air flow groove 544, and the temperature and humidity sensor 27 is at least partially accommodated in the air flow groove 544. The bottom of the bottom shell 5 is provided with a second air vent 545 at the position where the air flow groove 544 is located. In this embodiment, the air flow groove 544 is provided on the bottom shell 5, and the air flow groove 544 remains stationary. When the button housing 1 moves, the circuit board 2 and the temperature and humidity sensor 27 generate relative movement relative to the air flow groove 544, thereby enhancing the air circulation in the air flow groove 544 and further improving the accuracy of the temperature and humidity sensor 27 in detecting the ambient temperature and humidity. The second air vent 545 is connected to the outside to facilitate the introduction of external air into the air flow groove 544. The technical details of the air flow groove 544 and the second air vent 545 have been described in detail above and will not be repeated here.

[0122] Furthermore, the button housing 1 includes a button top wall and a button side wall 16 extending downward from the four sides of the button top wall. The button housing 1 is covered on the bottom shell 5, and the button side wall 16 surrounds the bottom shell 5, thereby improving the integrity of the shell and improving the dust and water splash resistance. The temperature and humidity sensor 27 is arranged at the edge of the circuit board 2, and the button side wall 16 is provided with a first air vent 161 at the position corresponding to the temperature and humidity sensor 27. When the button housing 1 is pressed, the button housing 1 and the circuit board 2 move relative to the bottom shell 5, driving external air into the air flow groove 544 through the first air vent 161 and / or the second air vent 545, thereby improving the accuracy of the temperature and humidity sensor 27 in detecting the ambient temperature and humidity. It is worth mentioning that the first air vent 161 and the second air vent 545 are respectively provided on the side and the bottom, which increases air circulation. The technical details of the button housing 1 have been described in detail above and will not be repeated here.

[0123] Furthermore, the bottom case 5 includes side walls, a bottom wall, a first partition wall 541, a second partition wall 542, and a third partition wall 543. These side walls, bottom wall, first partition wall 541, second partition wall 542, and third partition wall 543 collectively form the airflow groove 544. The bottom wall defines a second air vent 545 at the location of the airflow groove 544. The first partition wall 541, second partition wall 542, and third partition wall 543 can also reduce the impact of heat generated by other electronic components on the accuracy of the temperature and humidity sensor 27. The technical details of the bottom case 5 have been described in detail above and will not be repeated here.

[0124] Furthermore, a connecting opening 546 is provided on the side wall of the bottom shell at a position directly opposite to the first air vent 161. The connecting opening 546 connects the first air vent 161 with the air flow groove 544, which is beneficial for external air to enter the air flow groove 544 unimpeded from the first air vent 161, thereby improving the detection accuracy of the temperature and humidity sensor 27.

[0125] In some embodiments, as Figure 2 and Figure 7 As shown, a display screen 3 is disposed between the circuit board 2 and the key housing 1. The circuit board 2 and the display screen 3 move integrally with the key housing 1. The key housing 1 is provided with a display window 11 at a position corresponding to the display screen 3. The detection results of the temperature and humidity sensor 27 are displayed on the display screen 3. The technical details of the display screen 3 are described in detail above and will not be repeated here.

[0126] Furthermore, a conductive adhesive strip is sandwiched between the display screen 3 and the circuit board 2. The display screen 3 is electrically connected to the circuit board 2 via the conductive adhesive strip. The conductive adhesive strip is disposed at the end of the circuit board 2 away from the electronic switch 21, placing the display screen 3 close to the end of the circuit board 2. This facilitates reducing the size of the wireless switch 100. The technical details of the conductive adhesive strip are described in detail above and will not be repeated here.

[0127] In some embodiments, the button housing 1 is pivotally connected to the bottom housing 5. The circuit board 2 includes a first end proximate to the pivot axis 511 and a second end distal to the pivot axis 511. The temperature and humidity sensor 27 is disposed at the first end of the circuit board 2, and the electronic switch 21 is disposed in an area proximate to the second end of the circuit board 2. The pivotal connection between the button housing 1 and the bottom housing 5 makes the structure more concise and facilitates further reduction in size. The technical details of the button housing 1, bottom housing 5, circuit board 2, electronic switch 21, and temperature and humidity sensor 27 are described in detail above and will not be repeated here.

[0128] Furthermore, if Figure 9 As shown, the horizontal distance between the temperature and humidity sensor 27 and the pivot axis 511 is set to L1, and the horizontal distance between the electronic switch 21 and the pivot axis 511 is set to L2. If L1 / L2 is too small, the movement amplitude of the temperature and humidity sensor 27 during the pressing process of the key housing 1 is small, and the air circulation in the airflow groove 544 is slow, affecting the detection accuracy of the temperature and humidity sensor 27. If L1 / L2 is too large, when the right end of the key housing 1 is pressed, the left end of the key housing 1 tilts up significantly, resulting in a wide gap between the key housing 1 and the bottom shell 5, affecting the integrity of the housing. To this end, in this embodiment, L1 and L2 satisfy the relationship: 0.25≤L1 / L2≤0.7, so that the movement amplitude of the left end of the key housing 1 is within an appropriate range, while ensuring the detection accuracy of the temperature and humidity sensor 27, while avoiding an excessively large gap between the key housing 1 and the bottom shell 5.

[0129] In some embodiments, as Figure 5 As shown, a double-sided tape 55 is provided on the side of the bottom shell 5 away from the button housing 1. The bottom of the bottom shell 5 is mounted externally via the double-sided tape 55, and the second air vent 545 is not covered by the double-sided tape 55. Furthermore, the double-sided tape 55 is circular and affixed to the center of the bottom surface of the bottom shell 5. The lower surface of the double-sided tape 55 protrudes from the lower surface of the bottom shell 5, so that when the bottom shell 5 is affixed to the mounting surface, the second air vent 545 does not contact the mounting surface, thereby preventing the second air vent 545 from being blocked.
