At present, most of intelligent switches with key types are provided with characters or patterns printed on the keys in advance to prompt key functions, and if a user changes the corresponding functions of the keys, the keys need to be synchronously replaced, which brings inconvenience to the user and causes waste. To solve this problem, referring to fig. 1-24, the present utility model provides an intelligent switch 100 that is specifically illustrated. As shown in fig. 1 to 5, the smart switch 100 includes a panel base 1, a pressing part 2, and a display device 10; the pressing part 2 is connected to the panel base 1, and the pressing part 2 comprises a plurality of keys 21; the display device 10 includes a plurality of display screens 101 corresponding to the keys 21 one by one, and each display screen 101 is disposed on the panel substrate 1 and is used for displaying key information corresponding to the key 21; the intelligent switch 100 provided by the utility model can display the corresponding information of each key 21 through the display screen 101, and a user can change the display content of the display screen 101 to adapt to the change of key functions, so that the problem that patterns or characters need to be changed by changing the keys 21 in the prior art is solved. It should be understood that the number of the display screens 101 is equal to the number of the keys 21, and the positions of the display screens 101 correspond to the positions of the keys 21, for example, each display screen 101 may be disposed near an end of each key 21. The advantage of using multiple independent display screens 101 over using a single display screen 101 is that the effective utilization of the display area of a single display screen 101 is improved, the white space is reduced, and when one of the display screens 101 is damaged, the display screen 101 can be replaced independently, thereby saving maintenance costs.

In addition, as shown in fig. 1 to 5, one end of each key 21 of the intelligent switch 100 provided by the utility model is connected to form a connection end 22 of the pressing portion 2, and the other end of each key 21 far away from the one end is separated from each other to form a pressing end 23 of the pressing portion 2, so that when one key 21 performs a pressing motion, other keys 21 do not follow the motion, and each key 21 provides a reset force to each other through the connection end 22, and each display screen 101 is disposed close to the connection end 22. The keys 21 may be integrally connected to each other at one end, or the keys 21 may be fixedly connected to each other by a fixing piece, or may be connected in other forms. The keys 21 provide a restoring force to each other, which is understood to mean that the ends of the keys 21 are connected by the connecting end 22, when one of the keys 21 is pressed, the key 21 drives the connecting end 22 to generate a movement trend, and the connecting end 22 is kept stationary under the connection action of the other keys 21, so that the connecting end 22 and the pressed key 21 are deformed, and a restoring force is generated. The display screens 101 are disposed near the connection end 22, which means that the display screens 101 are disposed near the end of each key 21 in a one-to-one correspondence.

According to the intelligent switch 100 provided by the utility model, the end parts of the keys 21 are connected with each other, so that the intervals among the keys 21 are kept consistent, and the position corresponding relation between the keys 21 and the display screen 101 is more accurate; meanwhile, since the end parts of the keys 21 are connected, reset force can be provided between the keys 21, and an additional reset structure is not needed, so that the structure is simplified; in addition, the keys 21 are connected, so that the keys 21 cannot shake, and cannot be loosened and collapsed, and the pressing hand feeling is improved.

According to an embodiment of the present utility model, as shown in fig. 9 and 13, the intelligent switch 100 further includes a bottom case 3 provided with a mounting hole 31, the mounting hole 31 is used for mounting externally, and the pressing portion 2 covers the mounting hole 31; when the user installs the intelligent switch 100, the user only needs to detach the pressing part 2 to expose the installation hole 31, and then the installation screw 32 can be connected into the cassette of the wall through the installation hole 31, so as to fix the intelligent switch 100 to the wall; the installation need not to pull down panel base member 1, has protected inside circuit board 5, avoids circuit board 5 to follow panel base member 1 and has the risk of dropping and breaking after being pulled down.

Since the intelligent switch 100 provided by the utility model can be externally installed only after the key 21 is disassembled, the key 21 needs to have the characteristic of easy disassembly, and each key 21 cannot be disassembled one by one during the disassembly so as to avoid the connection end 22 connected with each key 21 from being broken off. Based on this, the embodiment of the utility model provides a row of keys 21 which are convenient to disassemble and assemble, and the row of keys 21 comprise a plugging structure 241, an abutting structure 242 and a movable clamping structure 243, and the three structures are mutually matched so as to realize the easy disassembly and assembly effect of the keys 21. As shown in fig. 6, 3 and 9, the connection end 22 of the pressing portion 2 is provided with the plugging structure 241, the panel base 1 is provided with the plugging position 11, the plugging structure 241 is plugged into the plugging position 11 so as to be limited by the plugging position 11 to move towards a fifth direction opposite to the direction in which the key 21 is pressed, wherein fig. 5 is a top view of the intelligent switch 100, fig. 6 is a step-a cross-sectional view in fig. 5, and it should be noted that the plugging structure 241, the abutting structure 242 and the movable clamping structure 243 are not on the same vertical plane (as can be seen in fig. 3), and fig. 6 concentrates the three on the same cross-section by means of step-sectioning, so that the structure can be more intuitively displayed. The fifth direction is the vertically upward direction in fig. 6, which has been marked in fig. 6. The plugging structure 241 may be a plug tongue, a latch, a plugboard or other plugging structure. The plugging direction of the plugging structure 241 may be a horizontal direction in fig. 6, an upward inclined direction, or a downward inclined direction, and the plugging position 11 may abut against the upper surface of the plugging structure 241 during the movement of the key 21, so as to limit the movement of the plugging structure 241 toward the fifth direction.

The connection end 22 of the pressing portion 2 is provided with the abutting structure 242 toward a second direction, the abutting structure 242 is disposed between the plugging structure 241 and the pressing end 23, the second direction is the same as the direction in which the key 21 is pressed, the second direction is a vertically downward direction in fig. 6, and the second direction is already marked in fig. 6; the panel base 1 has a supporting and limiting structure 12 at a position corresponding to the abutting structure 242, the abutting structure 242 abuts against the supporting and limiting structure 12, the supporting and limiting structure 12 can limit the plugging structure 241 to separate from the plugging position 11, wherein when the abutting structure 242 abuts against the supporting and limiting structure 12, the two cooperate to limit the key 21 to move horizontally, so as to limit the plugging structure 241 to separate from the plugging position 11 rightward. As shown in fig. 7, which is a schematic diagram of the pressing end 23 of the pressing portion 2 when the pressing end 23 is pressed, the pressing end 23 moves with the supporting and limiting structure 12 as a pivot, and the key 21 may pivot with the supporting and limiting structure 12 as a pivot, so as to drive the pressing end 23 to move; or the key 21 deforms by taking the supporting and limiting structure 12 as a fulcrum, and the pressing end 23 is driven to move downwards by the deformation of the key 21, so that the detecting piece 52 is triggered. The movable clamping structure 243 is disposed at the position of each key 21 near the pressing end 23 toward the second direction, the movable clamping structure 243 is clamped to the panel base 1, the pressing end 23 of the key 21 can be restricted from being separated from the panel base 1 toward the fifth direction, and the movable clamping structure 243 can move toward the second direction.

As shown in fig. 8, fig. 8 is a schematic diagram illustrating a disassembly process of the pressing portion 2 in fig. 6, when the pressing portion 2 is disassembled from the panel base 1, a user may first break the pressing end 23 upward, so that each movable clamping structure 243 is separated from the panel base 1, the pressing portion 2 may rotate counterclockwise based on the whole plugging structure 241, and when the rotation angle reaches a certain value, the abutting structure 242 is separated from the supporting and limiting structure 12, so that the pressing portion 2 loses the limitation of the supporting and limiting structure 12, and the plugging structure 241 can be separated from the plugging position 11 rightward. The whole disassembly process is simple and quick, and is suitable for the characteristics that the intelligent switch 100 needs to be installed outwards after the pressing part 2 is disassembled. In addition, compared with the prior art that each key 21 is provided with a hole site and is rotationally connected with the panel substrate 1, the scheme of matching the plugging structure 241 with the abutting structure 242 is adopted in the embodiment, so that the pressing part 2 can be integrally detached from the panel substrate 1 without detaching the keys 21 one by one, and the connection ends 22 for connecting the keys 21 are prevented from being broken off, therefore, the detaching scheme of the pressing part 2 provided by the embodiment is more suitable for the continuous row key 21 structure of the utility model.

Correspondingly, the installation process of the pressing portion 2 is opposite to the detachment process, as shown in fig. 8, when the pressing portion 2 is installed on the panel substrate 1, the plugging structure 241 may be first obliquely inserted into the plugging position 11 toward the lower left, and then the whole pressing portion 2 is turned clockwise based on the plugging structure 241, so that the abutting structure 242 abuts against the supporting and limiting structure 12, and finally the pressing end 23 is pressed downward, so that the movable clamping structure 243 is clamped on the panel substrate 1, thereby completing the installation. The whole installation process is fast and convenient, and is suitable for the characteristic that the pressing part 2 needs to be installed on the panel base body 1 after the intelligent switch 100 is installed on a wall.

Further, as shown in fig. 8, in the process of installing and detaching the pressing part 2, when the pressing part 2 is tilted, the left end of the pressing part 2 abuts against the transparent cover plate 4, so as to ensure that the pressing part 2 can be smoothly detached and installed, as shown in fig. 6, a certain gap is provided between the left end of the pressing part 2 and the transparent cover plate 4, and the gap reserves a space for the pressing part 2, so that in the process of installing and detaching the pressing part 2, when the pressing part 2 is tilted, the transparent cover plate 4 does not interfere with the pressing part 2.

Further, as shown in fig. 11, the circuit board 5 is fixedly connected to the panel base 1 by a plurality of fixing screws 554, so as to facilitate the disassembly and assembly of the circuit board 5 and thus the disassembly and assembly of the display screen 101. The display 101 is connected to the circuit board 5 through a flat cable 1013 so as to disconnect the display 101 from the circuit board 5 when the circuit board 5 is detached. Thereby improving the efficiency of replacing the display screen 101.

According to an embodiment of the present utility model, as shown in fig. 14, the circuit board 5 is provided with a flat cable connection terminal 57, the display screen 101 is provided with a flat cable 1013 toward the third direction, the third direction is a direction in which the pressing end 23 of the pressing portion 2 faces the connection end 22, and the third direction is marked in fig. 14 after the flat cable 1013 is bent and inserted into the flat cable connection terminal 57. In the embodiment of the utility model, the flat cable 1013 of the display screen 101 is arranged in the direction away from the key 21, so that the distance between the display screen 101 and the key 21 is closer, and the indication effect is better; and the flat cable 1013 and the pressing part 2 are prevented from being stacked in the thickness direction, and the flat cable 1013 is prevented from being damaged due to the fact that the pressing part 2 moves to drive the flat cable 1013 to move while the thickness of the intelligent switch 100 is thinned.

Further, as shown in fig. 14 and 11, a supporting foam 59 is disposed between the display screen 101 and the circuit board 5, and the supporting foam 59 provides a supporting force for the display screen 101. The upper end of the supporting foam 59 is abutted against and stuck to the display screen 101, the lower end is abutted against the circuit board 5, and the supporting foam 59 is in a compressed state, so that a supporting force is provided for the display screen 101, and the display screen 101 is connected with the panel base body 1 more stably. Wherein the flat cable connection terminal 57 is disposed below the supporting foam 59 and covered by the supporting foam 59, so that the flat cable 1013 is more stably connected with the flat cable connection terminal 57.

According to an embodiment of the present utility model, as shown in fig. 20 and 5, a side of the transparent cover plate 4 facing the panel base 1 is provided with a light shielding layer 42; the light shielding layer 42 is provided with a display window 421 at a position opposite to the display area 1012, and the content displayed in the display area 1012 is displayed outwards through the display window 421; the light shielding layer 42 is specifically a black coating, and is printed on the back surface of the transparent cover plate 4 by a silk-screen printing method. The light shielding layer 42 serves to cover the internal structure and enhance the aesthetic appearance. Since the circuit board 5 is equipped with a strong current circuit and a weak current circuit, the display screen 101 is regarded as a charged body, and the creepage distance between the display screen 101 and the outer surface of the switch needs to be greater than 2mm to avoid electric shock to the user, for this purpose, as shown in fig. 14, a preset gap is provided between the transparent cover plate 4 and the display screen 101, so that the creepage distance between the display screen 101 and the upper surface of the transparent cover plate 4 is increased. In an embodiment, the preset gap is 1.2mm, and the thickness of the transparent cover plate 4 is 2mm.

However, due to the existence of the preset gap, when the smart switch 100 is mounted on the wall, a part of the upper end of the display area 1012 is blocked by the light shielding layer 42 (as shown in fig. 21, since the smart switch 100 is mounted on the wall at a position generally lower than the human eye, the viewing angle of the human eye looking at the display screen 101 is a downward inclined viewing angle, which results in that the upper edge of the display window 421 blocks a part of the display area 1012). For this reason, one end of the display area 1012 facing the fourth direction is provided with a blank area (not shown in fig. 21) in which no content is displayed so as to avoid the display content from being blocked by the light blocking layer 42; wherein the fourth direction is the same direction as the vertical upward direction when the smart switch 100 is mounted on a wall, in this embodiment, the fourth direction is the same direction as the third direction, and the fourth direction is shown in fig. 21. The blank area is set as the upper lateral area of the display area 1012. Further, as shown in fig. 21, the display window 421 is disposed opposite to the display area 1012, and the size of the display window 421 is slightly larger than the size of the display area 1012, so as to reduce the shielding amount of the display window 421 to the display area 1012.

According to an embodiment of the present utility model, as shown in fig. 6, the transparent cover 4 is disposed in parallel with the connection end 22 of the pressing portion 2, and a surface of the transparent cover 4 facing the fifth direction is flush with a surface of the pressing portion 2 facing the fifth direction. In an embodiment, when the pressing portion 2 is not pressed, the transparent cover plate 4 and the pressing portion 2 are both in a horizontal state in fig. 6.

According to an embodiment of the present utility model, as shown in fig. 11 and 20, the circuit board 5 is provided with an infrared detection device 20, and the infrared detection device 20 includes: an infrared emission unit 201 for emitting a detection wave; an infrared receiving unit 202 is configured to trigger the display screen 101 when the detection wave is received. Wherein, the infrared detection device 20 is used for detecting the distance between the external object and the intelligent switch 100, and when the distance is close enough, the display screen 101 is triggered. Specifically, the detected wave emitted by the infrared emitting unit 201 is reflected by an external object and then transmitted to the infrared receiving unit 202, the closer the distance between the external object and the infrared receiving unit 202 is, the stronger the intensity of the reflected detected wave detected by the infrared receiving unit 202 is, when the intensity of the detected wave detected by the infrared receiving unit 202 is greater than a threshold value, the intelligent switch 100 determines that the distance between the external object and the intelligent switch 100 is smaller than a predetermined distance, and then the display screen 101 is controlled to be turned on. Wherein the detection wave may be an infrared light wave or other electromagnetic waves. Further, the transparent cover 4 covers the infrared emitting unit 201 and the infrared receiving unit 202, and the detection wave passes through the transparent cover 4 to be detected.

The inventor finds that the detection wave sent by the infrared emission unit 201 is easily transmitted to the infrared unit from the inside of the intelligent switch 100 through two error ways, so that the infrared detection device 20 misjudges, and one is that the detection wave is transmitted to the infrared receiving unit 202 through total internal reflection of the transparent cover plate 4; the other is that the detection wave is transmitted to the infrared receiving unit 202 through the gap between the panel base 1 and the circuit board 5, or when the panel base 1 is thin and light in color, the detection wave is transmitted directly to the infrared receiving unit 202 through the panel base 1. To attenuate these two erroneous routes of delivery, the present utility model employs the following scheme: as shown in fig. 20, 11 and 6, the infrared emitting unit 201 includes an infrared light emitting tube 2012, and the infrared receiving unit 202 includes an infrared receiving head 2021; at least one display screen 101 is disposed between the infrared light emitting tube 2012 and the infrared receiving head 2021, so that the distance between the infrared receiving head 2021 and the infrared light emitting tube 2012 is increased, thereby weakening the total reflection of the detection wave inside the transparent cover plate 4; the shielding member 58 is disposed around the periphery of the infrared light emitting tube 2012, and the shielding member 58 blocks the detection wave on the side surface of the infrared light emitting tube 2012, so that the transmission of the detection wave to the infrared receiving unit 202 through the gap between the panel substrate 1 and the circuit board 5 or through the panel substrate 1 is reduced. By the two schemes, the transmission of detection waves inside the intelligent switch 100 is weakened, and misjudgment of the infrared detection device 20 is avoided.

It should be noted that, increasing the distance between the infrared receiving head 2021 and the infrared light emitting tube 2012 can prevent small objects such as flies and mosquitoes from triggering the infrared detecting device 20 by mistake to a certain extent, specifically, when the flies and mosquitoes rest on the switch surface, the body can only cover one of the infrared light emitting tube 2012 or the infrared receiving head 2021 due to the small volume of the flies and mosquitoes, which is insufficient for triggering the infrared detecting device 20.

In an embodiment, as shown in fig. 20, the number of the display screens 101 is three, the three display screens 101 are arranged at intervals along the first direction, the infrared light emitting tubes 2012 are disposed between the left display screen 101 and the middle display screen 101, and the infrared receiving head 2021 is disposed between the middle display screen 101 and the right display screen 101.

Further, as shown in fig. 6, 11 and 20, the shielding member 58 is a black ring-shaped foam, the ring-shaped foam surrounds the infrared light emitting tube 2012, the upper end of the ring-shaped foam abuts against the back glue 41 of the transparent cover plate 4, and the lower end abuts against the circuit board 5, so as to block the detection wave from passing through the ring-shaped foam from the side. It is noted that, since the annular foam is made of a flexible material, the annular foam can be tightly attached to the circuit board 5, so that the detection waves are prevented from being transmitted from the gap between the annular foam and the circuit board 5. Further, the panel substrate 1 is provided with a transmitting through hole 193 and a receiving through hole 194 at corresponding positions of the annular foam and the infrared receiving head 2021, the transmitting through hole 193 accommodates the annular foam and limits the annular foam, and the receiving through hole 194 accommodates the infrared receiving head 2021.

Further, as shown in fig. 20 and fig. 5, the light shielding layer 42 is provided with an emission window 422 at a position opposite to the infrared light emitting tube 2012, the light shielding layer 42 is provided with a receiving window 423 at a position opposite to the infrared receiving head 2021, and the infrared receiving head 2021 receives an external detection wave through the receiving window 423; the infrared light emitting tube 2012 emits the detection wave to the outside through the emission window 422, and the emission angle of the detection wave is limited to be less than 90 ° by the emission window 422. When the distance between the infrared light emitting tube 2012 and the light shielding layer 42 is fixed, the smaller the size of the emission window 422, the smaller the detection wave emission angle, the smaller the detection angle of the infrared detection device 20; when the size of the emission window 422 is constant, the larger the distance between the infrared light emitting tube 2012 and the transparent cover plate 4 is, the smaller the detection wave emission angle is, and the smaller the detection angle of the infrared detection device 20 is. The detection angle of the infrared detection device 20 can be accurately controlled by controlling the size of the emission window 422 and the distance between the infrared light emitting tube 2012 and the transparent cover plate 4. The embodiment of the present utility model controls the detection angle of the infrared detection device 20 to be less than 90 ° because the infrared detection device 20 is easily triggered by mistake when the detection angle is too large. When the detection angle is too small, the user is close to the intelligent switch 100 from the side, so that the inventor is verified by experiments to control the detection angle to be 30-60 degrees to reach a proper trigger range.

Further, as shown in fig. 20, the back glue 41 of the transparent cover plate 4 is provided with a first back glue hole 411, a second back glue hole 412 and a third back glue hole 413 at opposite positions of the display window 421, the emission window 422 and the receiving window 423, and the sizes of the first back glue hole 411, the second back glue hole 412 and the third back glue hole 413 are respectively larger than the sizes of the display window 421, the emission window 422 and the receiving window 423.

In another embodiment, as shown in fig. 22, the difference between the embodiment and the embodiment of fig. 1-21 is that the mating structure 241 is loosely mated with the mating position 11, when the key 21 is pressed, the pressing portion 2 pivots based on the first pivot 121, the mating structure 241 no longer provides a restoring force, and a restoring foam 29 is provided between each key 21 and the panel base 1, and the restoring foam 29 provides a restoring force. Compared with a spring, the foam has the characteristic of slow rebound, and the adoption of the foam to provide the reset force can enable the pressing hand feeling of the key 21 to have damping sense, so that the pressing hand feeling is more advanced. Further, a foam mounting position 291 is provided on the lower surface of the key 21, and the reset foam 29 is adhered to the foam mounting position 291. Further, in the first direction, reinforcing rib positions are provided on both sides of each key 21 for reinforcing rigidity of the key 21.

Further, as shown in fig. 22, a thinned inclined surface 261 is disposed on one side of each key 21 adjacent to other keys 21, and the thinned inclined surface 261 is used for thinning the edge of the key 21, so that the thickness of the key 21 near the connection structure 25 is thinned, and thus the linkage effect between the keys 21 is reduced, that is, the movement of one key 21 does not drive the movement of the adjacent other keys 21. In addition, the width of the injection mold at the position of the thinned inclined surface 261 can be increased by setting the thinned inclined surface 261 on the key 21, so that the corresponding injection mold at the position is not easy to damage, and particularly, if the thinned inclined surface 261 is not set on the key 21, the injection mold at the position corresponding to the dividing slit 26 is in a slender strip shape and is easy to damage, the thinned inclined surface 261 enables the thickness of the key 21 at the position corresponding to the dividing slit 26 to be thinned, and the corresponding injection mold at the position is widened, so that the strength of the injection mold is increased.

The display screen 101, the infrared light emitting tube 2012, and the infrared receiving head 2021 are juxtaposed in the first direction. The panel substrate 1 is provided with the display through hole 191, the transmitting through hole 193 and the receiving through hole 194 at the corresponding positions of the display area 1012, the infrared light emitting tube 2012 and the infrared receiving head 2021 of the display screen 101.
