Description

Technical Field

[0001] The invention relates to the field of switches, and in particular to a wireless switch. Background Art

[0002] A wireless switch is a device that uses wireless signals to turn devices on or off. It is usually used in smart home systems to control lights, electrical appliances, and other devices. Wireless switches are generally powered by batteries, do not need to be connected to power lines, and do not require complex wiring, which reduces installation costs and complexity; and the installation location can be moved at will, which is highly flexible.

[0003] In the prior art, a wireless switch with a display screen generally rigidly limits the display screen between a movable part and a panel, and a 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. Summary of the invention

[0004] One object of the present invention is to provide a wireless switch, wherein a display screen is limited by a circuit board and a button housing, thereby reducing the number of parts; and the button housing is pivotally connected to a bottom housing, thereby eliminating the need to design multiple elastic support members to suspend and support the button housing, thereby further reducing the number of parts.

[0005] Another object of the present invention is to provide a wireless switch. Compared with a rigid limiter, an embodiment of the present invention adopts an elastic signal transmission member and an elastic filling member to provide an elastic limiting force, which not only allows the display screen to be stably limited between the circuit board and the button housing, but also ensures stable conduction between the display screen and the circuit board; in addition, cooperation with the isolation structure not only provides stable support for the circuit board, but also effectively prevents the display screen from being crushed.

[0006] Another object of the present invention is to provide a wireless switch, wherein the display screen is limited inside the isolation structure without the need to set up other limiting structures.

[0007] Another object of the present invention is to provide a wireless switch, wherein the positioning ribs abut against the side of the display screen to limit the horizontal freedom of the display screen, the signal transmission member and the filling member abut against the lower surface of the display screen, and the button housing abuts against the upper surface of the display screen to limit the vertical freedom of the display screen, thereby limiting all the freedom of the display screen without the need to set up other additional limiting structures to limit the display screen.

[0008] Another object of the present invention is to provide a wireless switch, wherein the filling member and the signal transmission member are arranged side by side to stably support the display screen so that the display screen and the key housing are well abutted.

[0009] Another object of the present invention is to provide a wireless switch, wherein the circuit board squeezes the signal transmission member under the locking action of the locking member, so that the connection between the circuit board, the signal transmission member and the display screen is stable to ensure stable signal transmission.

[0010] Another object of the present invention is to provide a wireless switch, wherein one end of the circuit board is clamped to the button housing and the other end is locked with a locking member to improve assembly efficiency.

[0011] Another object of the present invention is to provide a wireless switch, wherein the connecting column not only positions the circuit board, but also plays the role of locking the circuit board, making the structure more compact.

[0012] Another object of the present invention is to provide a wireless switch, wherein the button housing uses a connecting column and a first buckle to position the two ends of the circuit board, without setting up a special positioning structure to position the circuit board, thereby ensuring the relative position accuracy between the circuit board and the button housing.

[0013] Another object of the present invention is to provide a wireless switch, wherein the pivot axis is close to the signal transmission component, so that the signal transmission component has a smaller movement range during the key pressing process, thereby ensuring stable signal transmission.

[0014] Another object of the present invention is to provide a wireless switch, wherein the electronic switch is arranged in an area close to the second end of the circuit board, so that the pressing stroke of the button shell to trigger the electronic switch is shorter. Shortening the active stroke of the button shell can make the reserved space at the bottom of the button shell smaller, and then the side of the button shell covers more of the bottom shell, thereby improving the overall sense of the wireless switch.

[0015] Another object of the present invention is to provide a wireless switch, wherein the side wall of the button surrounds the bottom shell, thereby improving the integrity of the shell and enhancing the dustproof and splashproof performance.

[0016] Another object of the present invention is to provide a wireless switch, wherein the entire upper shell of the wireless switch is constructed as a key shell, so that the pressing area of ​​the key shell is larger, the pressing feel is improved, and it is beneficial to ensure a good pressing feel when the volume of the wireless switch is small.

[0017] Another object of the present invention is to provide a wireless switch, wherein the temperature and humidity sensor is arranged at the edge of the circuit board, so that when the button housing is pressed, the temperature and humidity sensor moves up and down with a larger amplitude, which is beneficial to improving the sensing accuracy of the temperature and humidity sensor.

[0018] Another object of the present invention is to provide a wireless switch, wherein a temperature and humidity sensor is arranged on the lower surface of the circuit board. When the button housing is pressed, the distance between the circuit board and the bottom shell changes, thereby disturbing the air flow between the circuit board and the bottom shell, further improving the sensing accuracy of the temperature and humidity sensor.

[0019] Another object of the present invention is to provide a wireless switch, wherein an air flow groove is connected to the outside through a first air hole and a second air hole. When the button housing is pressed, the button housing and the circuit board move relative to the bottom shell, driving the external air into the air flow groove through the first air hole and / or the second air hole, thereby improving the accuracy of the temperature and humidity sensor in detecting the ambient temperature and humidity.

[0021] Another object of the present invention is to provide a wireless switch, in which the weight of a button battery is added to a key housing. Since the button battery is heavy, the inertia of the key housing is increased, so that the key housing has a counterweight greater than its own weight during the pressing movement, making the pressing feel of the key housing heavier, and allowing a key housing made of plastic material to have a pressing texture similar to that of metal material.

[0064] In the description of the present invention, the terms "inside", "outside", "horizontal", "vertical", "up", "down", "top", "bottom", "left", "right" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and are not required that the present invention must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0065] In the description of the present specification, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0066] In the description of the present invention, unless otherwise clearly specified and limited, the term "connection" and other terms should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0067] The following will be combined with the 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 described embodiments 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 must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0068] In the prior art, wireless switches with display screens generally rigidly limit the display screen between the movable part and the panel, and 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, the panel and the movable part will not fit together, affecting the stability of the adhesion, and 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 product quality.

[0069] Based on this, the present invention provides a wireless switch 100, which is dedicated to weakening the influence of the size error of the accommodating groove on the positioning of the display screen.

[0070] See also Figure 1-Figure 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 .

[0071] The key housing 1 is movably connected to the bottom housing 5; the circuit board 2 is installed on the back of the key housing 1. The display screen 3 is limited by the circuit board 2 and the key housing 1, and 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 a side of the circuit board 2 facing the bottom housing 5, and when the key housing 1 moves based on the bottom housing 5 in response to the pressing force, the circuit board 2, the display screen 3 and the electronic switch 21 move integrally with the key housing 1, and the electronic switch 21 presses against the bottom housing 5 during the movement so that the electronic switch 21 is triggered.

[0072] 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.

[0073] The movable connection can be understood as a connection mode that can generate relative motion, such as pivot connection, sliding connection, 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 the pressing force.

[0074] The display window 11 may be a through hole or a transparent area, and the display content of the display screen 3 is displayed to the outside through the display window 11. The display screen 3 is limited by the circuit board 2 and the key housing 1, which can be understood as 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 limit the display screen 3, or can indirectly abut against the upper and lower surfaces of the display screen 3 through other parts to limit the display screen 3. In a specific example, the circuit board 2 abuts against the lower surface of the display screen 3 through the signal transmission member 22 and the filling member 23.

[0075] In the embodiment of the present invention, the display screen 3 is limited by the circuit board 2 and the key housing 1, which reduces the number of parts; and the key housing 1 is pivotally connected to the bottom shell 5, so that there is no need to design multiple elastic support members to suspend and support the key housing 1, and the number of parts is further reduced. It is worth mentioning that the display screen 3 and the circuit board 2 move together with the key housing 1, so that 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 heavier, bringing a more textured pressing experience.

[0076] Furthermore, if Figure 8 and Figure 12-Figure 15 As shown, Figure 12-Figure 15This is the viewing angle of the wireless switch 100 after being turned 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 against the circuit board 2 to isolate the circuit board 2 from 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 transmitted to the electronic switch 21 through the circuit board 2, so that the electronic switch 21 presses against the bottom shell 5; wherein, the circuit board 2 is isolated from the display screen 3 by a predetermined distance, so that the transmission path of the pressing force does not pass through the display screen 3, thereby preventing the display screen 3 from being crushed; at the same time, the isolation structure 12 rigidly supports the circuit board 2, so that the circuit board 2 has higher stability.

[0077] In addition, in this embodiment, Figure 7 and Fig.16 As shown, an elastic signal transmission member 22 and an elastic filling member 23 are arranged between the circuit board 2 and the display screen 3. The signal transmission member 22 is arranged 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 maintain abutment state. The signal transmission member 22 can be conductive rubber, metal springs 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, for example, it can be foam, rubber, silicone or made of other elastic materials.

[0078] To sum up, compared with the rigid limitation of the display screen in the prior art, this embodiment adopts 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.

[0079] In addition, the elastic signal transmission member 22 and the elastic filling member 23 cooperate with the isolation structure 12 to not only provide a stable support for the circuit board 2 but also effectively prevent the display screen 3 from being crushed.

[0080] Furthermore, if Fig.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 inside the isolation structure 12 without providing other limiting structures.

[0081] 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.

[0082] In some embodiments, Fig.16 As shown, the signal transmission member 22 is a conductive rubber strip, the filler 23 is a strip structure, the filler 23 is located at one end of the display screen 3 away from the signal transmission member 22, and the filler 23 and the signal transmission member 22 are arranged in parallel to stably support the display screen 3, so that the display screen 3 and the key housing 1 are well abutted. The parallel arrangement can be understood as a parallel arrangement or an angle between the two being less than 30°.

[0083] In this embodiment, the signal transmission member 22 and the filling member 23 are arranged in parallel at two ends of the display screen 3. Furthermore, the filling member 23 is adhered to the circuit board 2.

[0084] Furthermore, if Fig.16 As shown, the conductive rubber 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, and 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 rubber strip, and the first conductive portion 31 is composed of a plurality of conductive contacts arranged, such as Fig.17 As shown, the circuit board 2 is provided with a second conducting portion 24 at a position corresponding to the conductive rubber strip. The second conducting portion 24 is composed of a plurality of metal contacts arranged. The metal contacts are connected to the conducting contacts through the conductive rubber strip to realize signal transmission between the display screen 3 and the circuit board 2.

[0085] In some embodiments, Fig.10 and Fig.12As shown, one end of the circuit board 2 away from the signal transmission member 22 is clamped to the button housing 1, and one 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. The circuit board 2 squeezes the signal transmission member 22 under the locking action of the locking member 25, 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.

[0086] Furthermore, if Fig.13 As shown, the locking member 25 is set as two connecting screws, the button housing 1 is provided with a connecting column 13 at the position corresponding to the connecting screw, and the circuit board 2 is provided with a positioning hole 251 at the position corresponding to the connecting column 13, and the positioning hole 251 is positioned and matched with the connecting column 13, and the connecting screw is locked to the connecting column 13, so that the circuit board 2 is locked to the button housing 1. The connecting column 13 not only positions the circuit board 2, but also plays the role of locking the circuit board 2, making the structure more compact. Among them, the connecting column 13 extends from the button housing 1 toward the circuit board 2, and the end of the connecting column 13 is provided with a threaded connection hole adapted to the connecting screw, and the arrangement direction of the two connecting columns 13 is parallel to the extension direction of the conductive rubber strip; the connecting column 13 is located at the edge of the circuit board 2, and the positioning hole 251 of the circuit board 2 is semicircular, and its diameter is adapted to the diameter of the connecting column 13. When the circuit board 2 is installed in the button housing 1, the connecting column 13 is embedded in the positioning hole 251 to achieve positioning between the two. The height of the connecting column 13 is adapted to the thickness of the circuit board 2 , so that when the connecting screw is locked on the connecting column 13 , the circuit board 2 can be locked on the key housing 1 .

[0087] Furthermore, if Fig.12 As shown, the button housing 1 is provided with two first buckles 14 at one end away from the signal transmission member 22, and the first buckles 14 are used to clamp the circuit board 2. The circuit board 2 is provided with a positioning portion 26 between the two first buckles 14, and the width of the positioning portion 26 is adapted to the spacing between the two first buckles 14, so that the positioning portion 26 is positioned between the two first buckles 14; wherein the first buckles 14 extend downward from the top wall of the button housing 1, and the arrangement direction of the two first buckles 14 is parallel to the extension direction of the conductive rubber strip. Further, the positioning portion 26 is integrally formed with the circuit board 2.

[0088] The key housing 1 of this embodiment uses the connecting column 13 and the first buckle 14 to position the two ends of the circuit board 2, without providing a special positioning structure to position the circuit board 2, thereby ensuring the relative position accuracy between the circuit board 2 and the key housing 1.

[0089] 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. Among them, 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.

[0090] The circuit board 2 has a first end close to the pivot axis 511 and a second end away from the pivot axis 511, and the electronic switch 21 is arranged in a region close to the second end of the circuit board 2. According to the lever principle, the closer the electronic switch 21 is to the second end, the shorter the pressing stroke of the key housing 1 to trigger the electronic switch 21. Shortening the movable stroke of the key housing 1 can make the bottom space of the key housing 1 smaller, so that the side of the key housing 1 covers more of the bottom shell 5, and improves the overall sense of the wireless switch 100. Among them, the region close to the second end can be understood as the region near the second end.

[0091] 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, and the ends of the two pivot arms 51 are respectively provided with the pivot shafts 511 protruding therefrom, and the two pivot shafts 511 are arranged opposite to each other. Fig.11 and Fig.12 The button housing 1 is pivotally connected to the bottom housing 5 by an axial-hole connection. The button housing 1 is provided with connecting plates 15 on the inner sides of the two pivot arms 51 , respectively. The connecting plates 15 are provided with pivot holes 151 . The pivot shaft 511 is inserted into the pivot hole 151 , and the pivot shaft 511 can rotate in the pivot hole 151 .

[0092] Furthermore, if Fig.12 and Fig.10As shown, the first buckle 14 is provided with 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, and the second buckle 52 is buckled in the buckle hole 141, that is, the second buckle 52 is buckled in the first buckle 14, so that the structure is more compact, which is conducive to reducing the thickness of the wireless switch 100. Further, the first buckle 14 includes a first arm extending from the button housing 1 and a first hook provided at the end of the first arm, the first hook is engaged with the circuit board 2, and the buckle hole 141 is provided in the first arm.

[0093] In some embodiments, Figure 7 As shown, the trigger part 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 separate reset mechanism, 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 trigger feedback of the electronic switch 21 can be more clearly transmitted to the button housing 1, and the pressing feel is better. The trigger part 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 trigger part 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 part of the electronic switch 21, and the trigger protrusion 53 is used to accurately trigger the trigger part. Furthermore, when the button housing 1 does not receive a pressing force, the trigger protrusion 53 still presses the trigger part, so that the trigger part is in a slightly compressed state, so that the trigger part can provide a pre-tightening force when the button housing 1 is not pressed, thereby preventing the button housing 1 from being loose.

[0094] In the existing wireless switch with display screen, the panel is fixed to the movable part. The panel is pressed downward to drive the movable part to move downward. The position of the middle shell is fixed. The panel moves relative to the middle shell. A pressing gap needs to be reserved between the panel and the middle shell. This gap makes the dust and splash resistance of the wireless switch poor and destroys the integrity of the shell. To solve this problem, in this embodiment, if Figure 1-Figure 5 As shown, in this embodiment, thanks to the fact that the circuit board 2, the display screen 3 and the electronic switch 21 are all fixedly connected to the key housing 1, and no reset mechanism is required, the key housing 1 can cover more area of ​​the bottom shell 5, thereby improving the integrity of the shell and improving the dustproof and splashproof performance. The key housing 1 includes a key top wall and a key side wall 16 extending downward from the four sides of the key top wall. The key housing 1 is covered on the bottom shell 5, and the key side wall 16 surrounds the bottom shell 5.

[0095] The entire upper shell of the wireless switch 100 is constructed as a key shell 1, so that the pressing area of ​​the key shell 1 is larger, the pressing feel is improved, and it is beneficial to ensure a good pressing feel when the volume of the wireless switch 100 is small.

[0096] Furthermore, if Figure 7 As 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 penetrating the button housing 1. Thanks to the elastic supporting force provided by the filling member 23 and the signal transmission member 22, the upper surface of the display screen 3 can fit tightly 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.

[0097] 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, and the pressing mark 17 is used to indicate the correct pressing area so that the user can trigger the electronic switch 21 more effortlessly. The pressing mark 17 is constructed as an arc-shaped depression.

[0098] Furthermore, if Figure 7-Figure 8 As shown, Figure 7 for Figure 6 AA section 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 through 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 housing 1. Among them, the temperature and humidity sensor 27 is provided at the edge of the circuit board 2, so that when the key housing 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 housing 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, and further improving the sensing accuracy of the temperature and humidity sensor.

[0099] 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, 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, the circuit board 2 is covered on 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 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 to enter 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 the air circulation. In addition, the first partition wall 541, the second partition wall 542 and the third partition wall 543 can also reduce the influence of the heating of other electronic components on the accuracy of the temperature and humidity sensor 27.

[0100] In this embodiment, the air flow groove 544 is arranged on the bottom shell 5 , and the air flow groove 544 always remains in a stationary state. When the button housing 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 .

[0101] Furthermore, if Figure 7 and Fig. 9 As shown, Fig. 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, so that the air near the temperature and humidity sensor 27 can circulate, thereby improving the accuracy of the temperature and humidity sensor 27 in detecting the ambient temperature and humidity.

[0102] like Fig. 9As shown, the key housing 1 is pivotally connected to the bottom housing 5, the circuit board 2 includes a first end close to the pivot axis 511 and a second end away from the pivot axis 511, the temperature and humidity sensor 27 is arranged at the first end of the circuit board 2, and the electronic switch 21 is arranged in the area close to the second end of the circuit board 2, so as to avoid the conflict between the installation positions of the electronic switch 21 and the temperature and humidity sensor 27, and facilitate the electronic switch 21 and the temperature and humidity sensor 27 to be arranged at the middle position of the two ends of the circuit board 2, thereby improving the pressing feel of the key housing 1 and facilitating the arrangement of the air flow 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 arranged on the left and right sides of the pivot axis 511 respectively. When the electronic switch 21 moves downward in response to the 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 the initial position downward. The up and down movement of the electronic switch 21 can drive the temperature and humidity sensor 27 to move up and down, thereby improving the detection accuracy of the temperature and humidity sensor 27.

[0103] Furthermore, the temperature and humidity sensor 27 and the electronic switch 21 are arranged on the same surface of the circuit board 2, so that there is enough space on the side of the circuit board 2 opposite to the electronic switch 21 to arrange the display screen 3. Furthermore, the signal transmission element 22 and the temperature and humidity sensor 27 are arranged on the same end of the circuit board 2, but are arranged on the upper and lower surfaces of the circuit board 2.

[0104] 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 configured 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 .

[0105] Furthermore, if Figure 8 and Figure 4 As shown, the bottom shell side wall is provided with a communication port 546 at a position directly opposite to the first air vent 161, and the communication port 546 connects the first air vent 161 with the air flow groove 544, which is conducive to the unimpeded entry of external air into the air flow groove 544 from the first air vent 161, so as to improve the detection accuracy of the temperature and humidity sensor 27. Further, the communication port 546 is formed by the top of the bottom shell side wall being recessed downward.

[0106] Furthermore, if Fig. 9 As shown, the distance between the temperature and humidity sensor 27 and the pivot axis 511 in the horizontal direction is set to L1, and the distance between the electronic switch 21 and the pivot axis 511 in the horizontal direction 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 air flow groove 544 is slow, which affects the accuracy of the detection 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 to a large extent, which will cause a wide gap between the key housing 1 and the bottom shell 5, affecting the integrity of the shell. For this reason, 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 reaches an appropriate range, while ensuring the accuracy of the detection of the temperature and humidity sensor 27, avoiding too large a gap between the key housing 1 and the bottom shell 5.

[0107] Furthermore, if Figure 5 As shown, a double-sided adhesive tape 55 is provided on one side of the bottom shell 5 away from the button housing 1, and the bottom shell 5 is mounted externally through the double-sided adhesive tape 55, and the second air vent 545 is not covered by the double-sided adhesive tape 55. Further, the double-sided adhesive tape 55 is circular and is pasted on the center of the bottom surface of the bottom shell 5, and the lower surface of the double-sided adhesive tape 55 protrudes from the lower surface of the bottom shell 5, so that when the bottom shell 5 is pasted on the mounting surface, the second air vent 545 does not fit the mounting surface, thereby preventing the second air vent 545 from being blocked.

[0108] Furthermore, the display screen 3 is a broken screen, and the circuit board 2 is provided with a button battery 4, and the circuit board 2 is powered by the button battery 4; wherein, the button battery 4 is very small in size, which is conducive to the miniaturization of the wireless switch 100, but the button battery 4 generally has less power and poor battery life, so the display screen 3 uses a broken screen, which has no backlight, is very power-saving, and greatly improves the battery life of the button battery 4. In a specific embodiment, the button battery 4 uses a CR2032 battery, and the broken screen uses a 1.4-inch LCD broken screen, which displays information all the time and does not turn off the screen. When the broken screen is always working, the battery life can reach more than one year.

[0109] 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 heavier, 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 to have a pressing texture similar to that of metal.

[0110] 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.

[0111] 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, so as to facilitate battery replacement. Specifically, one end of the bottom shell 5 is connected to the key housing 1 through the pivot shaft 511, and the other end is clamped to the key housing 1 through the second buckle 52. The end of the bottom shell 5 close to the second buckle 52 is provided with a gripping part 57, which is recessed in the side of the bottom shell 5, and a force step is provided at the bottom of the gripping part 57. When the key housing 1 is buckled with the bottom shell 5, the force step at the bottom of the gripping part 57 is exposed under the key housing 1. The user can use the fingernail to pull the force step downward to disengage the second buckle 52 from the key housing 1, and then pry the bottom shell 5 downward to disengage the pivot shaft 511 from the pivot hole 151, so as to remove the bottom shell 5 from the key housing 1.

[0112] like Figure 4 and Fig.11 As shown, the pivot shaft 511 is arranged 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, so that the pivot shaft 511 can be inserted into / disengaged from the pivot hole 151. Meanwhile, the pivot arm 51 of the bottom shell 5 is relatively 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 bottom shell 5 to be detached from the key housing 1. It is worth noting that there is no need to worry about the pivot shaft 511 being disengaged from the pivot hole 151 during normal use, because the key housing 1 is generally subjected to pressure during normal use, such as Fig.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 the key housing 1 is pressed, thereby preventing the pivot shaft 511 from disengaging downward from the pivot hole 151. In addition, the bottom housing 5 is not provided with a finger-like structure at one end close to the pivot shaft 511, so it is difficult for the user to disengage the end during normal use, thereby preventing the pivot shaft 511 from disengaging from the pivot hole 151 during normal use.

[0113] Furthermore, if Fig.14 As shown, the circuit board 2 is provided with a conductive clamp 28, the button battery 4 is clamped and limited by the conductive clamp 28, and the button battery 4 is connected to the circuit board 2 through the conductive clamp 28. The button battery 4 is limited by the conductive clamp 28, which avoids the key housing 1 being provided with other limiting structures to limit the button battery 4.

[0114] Furthermore, if Fig.14 and Fig.13 As shown, it should be noted that Fig.13 and Fig.14 The perspective of 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. Fig.14 In the figure, the lower surface of the button battery 4 is the negative electrode, and the side and upper surface are the positive electrode. The circuit board 2 is provided with a conductive area (not shown) at the corresponding position of the button battery 4, the lower surface of the button battery 4 abuts against the conductive area, and the upper surface of the button battery 4 abuts against the conductive clamping wall 281. Among them, the circuit board 2 is provided with a large circular pad in the conductive area, and the negative electrode of the button battery 4 abuts against the circular pad to conduct the circuit board 2. Further, the conductive clamping member 28 is formed by cutting and bending a metal sheet.

[0115] 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.

[0116] Furthermore, if Fig.14 and Fig.13 As shown, the conductive clamp 28 has a loading end and a limiting end, the loading end is open, and the button battery 4 can be loaded horizontally into the conductive clamp 28 from the loading end; the conductive clamp 28 is provided with two vertical limiting blocks 284 at the limiting end, the limiting blocks 284 are bent at the conductive clamp wall 281, and the two limiting blocks 284 are located on both sides of the button battery 4 and are inclined to the loading direction of the button battery 4. The limiting blocks 284 not only have the function of preventing the button battery 4 from escaping, but also have the function of indicating the correct installation position, that is, when the button battery 4 abuts against the limiting blocks 284, it indicates that the button battery 4 has been installed in place.

[0117] Furthermore, if Fig.17 and Fig.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 onboard antenna 292. The onboard antenna 292 and the button battery 4 are respectively located on two sides of the circuit board 2, and the onboard antenna 292 is arranged at one end of the circuit board 2 away from the button battery 4; the onboard antenna 292 is laid on the circuit board 2 in a winding manner using a metal strip. Fig.18 is a top view of the circuit board 2, the display screen 3 is projected on the circuit board 2 to form a first projection pattern (the first projection pattern is Fig.18 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. Further, at least 80% of the area of ​​the onboard antenna 292 is located outside the first projection pattern.

[0118] Furthermore, if Fig.19 As shown in FIG. 2 , it is a schematic diagram of the structure of the onboard antenna 292. Fig.19 It is 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 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 integrally formed. The width W2 of the grounding strip is 0.9mm, the width W1 of the broken strip is 0.5mm, the width of the bending strip is 0.5mm, the distance D2 between the broken strip and the "J"-shaped protrusion is 1.7mm, the distance D3 between the two "J"-shaped protrusions is 1.7mm, the width L6 of the "J"-shaped protrusion is 3mm, the width L4 of the bending strip in the vertical direction is 3.14mm, and the distance D4 between the raised part of the tail end of the bending strip and the "J"-shaped protrusion is 1.7mm. Among them, the R&D personnel control the sum of the lengths of the broken 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 the 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 50Ω. Fig.19 The length of the neutral wire.

[0119] Furthermore, if Fig.17 As shown, the wireless communication module 291 is integrated with a processing module, which is used to detect whether the electronic switch 21 is triggered, so as to generate a corresponding control signal, and then send 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 through a Bluetooth module.

[0120] The wireless communication module 291 is disposed between the display screen 3 and the circuit board 2. A driving chip 293 is disposed 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 disposed outside the first projection pattern. Figure 7 As shown, the driving chip 293 and the electronic switch 21 are arranged on both sides of the circuit board 2 and at the same end to improve the space utilization inside the key housing 1. Furthermore, a part of the pins of the driving chip 293 are welded to the positioning part 26 of the circuit board 2 to save the space of the circuit board 2.

[0121] In another embodiment of the present invention, Fig. 20 and Fig.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.

[0122] This embodiment can not only be regarded as an extension and enrichment of the previous embodiment, but also can be improved or integrated with it to jointly construct a more comprehensive and flexible wireless switch implementation scheme. Of course, the wireless switch of this embodiment also has the possibility of independent implementation without relying on other embodiments. For those structural features and operating mechanisms shared with the previous embodiments, this embodiment will not be repeated to avoid repetition. Instead, this embodiment will focus on revealing the uniqueness of this embodiment.

[0123] Specifically, this embodiment and Figure 1-Figure 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, and the locking portion 58 includes a locking protrusion 581 and an unlocking protrusion 582. When the bottom shell 5 is buckled on 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 to disengage from the engagement, and the unlocking protrusion 582 can drive the locking protrusion 581 to resume engagement when the pressing is removed. 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 and pull the bottom shell 5 downward to remove the bottom shell 5 from the button housing 1, which increases the difficulty of disassembling the bottom shell 5, prevents the button battery 4 from being pulled out by children, and eliminates safety hazards.

[0124] Furthermore, if Fig. 20 and Fig.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, 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 on the elastic arm 584 from top to bottom, the unlocking protrusion 582 is pressed to deform the elastic arm 584, 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, so that the bottom shell 5 can be detached from the key housing 1. There are two support arms 583, which are respectively arranged on both sides of the elastic arm 584, and the tops of the two support arms 583 are respectively connected to the tops of the elastic arms 584, and the two support arms 583 and the elastic arm 584 are configured to present a shape similar to the capital letter "M" from a certain viewing 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.

[0125] 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 convenient for a user to press the unlocking protrusion 582 .

[0126] The button side wall 16 is provided with a third buckle 163 protruding inwardly and adapted to the locking protrusion 581 . The locking protrusion 581 is engaged with the third buckle 163 to limit the bottom shell 5 from being separated from the button housing 1 .

[0127] 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 .

[0128] Furthermore, if Fig.21 As shown, compared to Figure 1-Figure 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 then smoothly disengaged from the third buckle 163.

[0129] Furthermore, if Fig. 20 As shown, the pivot arm 51 and the second buckle 52 are both provided with reinforcing ribs for improving the strength and rigidity of the pivot arm 51 and the second buckle 52. Furthermore, an avoidance notch is provided at the upper corner of the airflow slot 544, and the avoidance notch is used to avoid interference with the electronic components on the circuit board 2.

[0130] In addition, in order to solve the problem that the button battery 4 is easily pulled out by children, in another embodiment of the present invention, a wireless switch is also provided. 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.

[0131] Specific as Fig. 22 As shown, this embodiment and Figure 1-Figure 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. Fig. 22 As shown, the conductive clamping member 28 provided in this embodiment is Figure 1-Figure 19 The difference between the conductive clamp 28 of the embodiment is that the conductive clamp 28 is provided with a limit spring piece 285 at the loading end. When the button battery 4 is loaded into the conductive clamp 28, the limit spring piece 285 engages the side of the button battery 4 to limit the button battery 4 from being separated from the conductive clamp 28 from the loading end. This prevents the button battery 4 from accidentally coming out, and increases the difficulty of removing the battery, preventing the button battery 4 from being easily removed, causing a safety hazard of accidental ingestion by children.

[0132] Furthermore, if Fig. 22 As shown, the limiting spring piece 285 includes an elastic section extending from the conductive clamping wall 281 and a limiting hook arranged 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 limit the button battery 4 from being disengaged. Further, the elastic section is elastic. When the button battery 4 needs to be taken out, two operations need to be performed simultaneously to take out 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 applying the first operation, the second operation is applied. The second operation is to push the button battery 4 from the limiting end of the conductive clamping member 28 toward the loading end to push 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 taking out the button battery 4 and prevents the button battery 4 from being taken out by children.

[0133] Furthermore, if Fig. 22 As shown, an operating recess 2811 is provided at one end of the conductive clamping wall 281 facing the limiting 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.
