A smart switch with anti-accidental touch function

Abstract

This utility model relates to the field of intelligent switch technology with anti-accidental touch function, specifically an intelligent switch with anti-accidental touch function, including a switch body, a display screen, a button, and an anti-touch component. The baffle of the anti-touch component is connected to the connecting frame through a rotating shaft. Under normal conditions, the baffle adheres to and covers the button under the action of a first spring, forming a physical protective barrier. When a pet bumps into it or a child plays, the baffle first bears the external force, preventing the button from being pressed directly. For example, when a pet's tail sweeps across the switch, the baffle rotates to buffer the impact, effectively preventing safety hazards caused by accidental activation of kitchen appliances, water heaters, and other equipment. The baffle covers the display screen. When the switch body is subjected to an accidental impact, such as furniture collision or falling objects, the baffle first contacts the external force and dissipates the force through the rotating shaft, reducing the impact force from directly acting on the display screen.

Description

Technical Field

[0001] This utility model relates to the field of intelligent switch technology with anti-accidental touch function, specifically to an intelligent switch with anti-accidental touch function. Background Technology

[0002] As is well known, a smart switch refers to a unit that uses a combination of control boards and electronic components and programming to achieve intelligent switching control of circuits. Switch control is also known as BANG BANG control. Because this control method is simple and easy to implement, it is used in the control of many household appliances and lighting fixtures.

[0003] Traditional push-button switches rely solely on the pressing travel to trigger the circuit, lacking effective recognition and judgment of triggering behavior. In daily life, accidental collisions by pets or unintentional touches by children while playing can trigger the switch, causing appliances to start or stop accidentally. This not only affects the convenience of home life but may also pose safety hazards, such as accidental activation of kitchen appliance switches leading to accidents. Furthermore, frequent accidental touches cause the display screen to be subjected to external impacts over a long period of time, making it prone to scratches, cracks, and other damage, thus shortening the product's lifespan.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] See Figures 1-8 A smart switch with anti-accidental touch function achieves dual protection for button 3 and display screen 2 through the physical protection of baffle 7 of anti-touch component 4 and linkage limiting structure. The core solution is as follows: baffle 7 of anti-touch component 4 is rotatably connected to the connecting frame 5 at the top of the switch body 1 through rotating shaft 6. Under normal conditions, it fits and covers button 3 under the action of the first spring 8 to form a protective barrier. When operation is required, push baffle 7 to rotate and expose button 3. At the same time, the position of baffle 7 is locked through structures such as sliding column 14 and limiting column 17. This device solves the problem of traditional smart switches causing electrical appliances to be accidentally started due to pet collisions or children accidentally touching them. At the same time, it reduces the risk of external impact on display screen 2, improves safety and product life.

[0032] First, refer to Figure 1 In this embodiment, the switch body 1 is a rectangular ABS engineering plastic shell, which integrates control circuit and wiring terminals. A groove is provided on the top for mounting the display screen 2 and button 3. Mounting holes are provided on the bottom of the body, which can be fixed to the wall or equipment panel by screws. The sides are provided with a first limiting hole 11, a first sliding groove 12 and a circular groove 13 to form a guiding and rotating structure for the sliding column 14. The sides are provided with a second sliding groove 20 and a square groove 23 for limiting the sliding installation of the plate 22. The structural design of the switch body 1 takes into account both circuit protection and the installation compatibility of external components. The shell thickness is uniform and the impact resistance is high, which can effectively protect the internal electronic components.

[0033] Display screen 2 is a 2.4-inch TFT color touch screen, fixed in the groove at the top of switch body 1. It is electrically connected to the internal control board via FPC cable and is used to display device status, operation menu and other information. Button 3 is a silicone button, embedded in the main panel below display screen 2. It has a built-in micro switch and controls the circuit on and off in conjunction with display screen 2. The surface of button 3 is covered with a wear-resistant coating, with a moderate pressing travel and clear tactile feedback. Together with display screen 2, it realizes human-computer interaction. The layout of display screen 2 and button 3 conforms to ergonomics, which facilitates visual observation and finger pressing during normal operation.

[0034] Then, refer to Figure 3In this embodiment, the anti-touch component 4 includes connecting frames 5 on both sides, a rotating shaft 6, a baffle 7 and a first spring 8. The connecting frames 5 are vertically fixed to the top two sides of the switch body 1, and are in the shape of a "U". The rotating shaft 6 passes through the middle. The baffle 7 is sleeved on the rotating shaft 6 through a bushing and can rotate around the shaft. The two baffles 7 are arranged opposite each other. Under normal conditions, they stick together under the torque of the first spring 8 (sleeved on both ends of the rotating shaft 6) and cover the area below the button 3 and the display screen 2. The baffle 7 is made of transparent PC material with a thickness of 2mm and a frosted surface treatment. It does not obstruct the display content of the display screen 2 and can withstand a certain amount of external impact (such as pet claws or children's slaps).

[0035] Secondly, see Figure 4 and Figure 8 In this embodiment, support plates 10 are fixed on both sides of the top of the switch body 1. The upper surface of the support plate 10 is attached to the lower surface of the baffle 7 to provide rotational support. Sliding columns 14 are slidably arranged in the first limiting holes 11 on both sides of the body. The first slider 15 is fixed in the middle of the column. The slider is slidably engaged with the first sliding groove 12 and can rotate in the circular groove 13. The side of the sliding column 14 is fixed with a limiting column 17 through a connecting plate 16. The limiting column 17 passes through the circular hole 18 on the baffle 7 and is slidably engaged with the placement hole 19. When the baffle 7 is pushed to rotate, the limiting column 17 moves along the circular hole 18, causing the sliding column 14 and the first slider 15 to rotate in the circular groove 13, thereby locking the angle of the baffle 7 (e.g., when rotated 90°, the limiting column 17 falls into the placement hole 19, fixing the position of the baffle 7).

[0036] Again, see Figure 5 In this embodiment, a second groove 20 is opened on the side of the switch body 1, and a sliding plate 21 is embedded in the groove. A limiting plate 22 is fixed on the side, and the limiting plate 22 slides in conjunction with the square groove 23. A second spring 24 is installed in the square groove 23 to push the limiting plate 22 to block the wiring gap between the side of the body and the outside world, preventing dust and moisture from entering. The mounting plate 25 is fixed to the side of the body, and the limiting shaft 26 passes through the small hole 27 on the limiting plate 22. A horizontal plate 28 is fixed at the top of the small hole 27, and a third spring 29 is set between the horizontal plate 28 and the mounting plate 25 to form double elastic protection. The design of the limiting plate 22 can effectively prevent external forces from directly hitting the side wiring port. At the same time, the spring structure allows the limiting plate 22 to retract slightly when it is impacted, thus buffering the external force.

[0037] In addition, see Figure 1In this embodiment, the baffle 7 covers the button 3 under the action of the first spring 8. When the pet's tail sweeps across the switch surface, the baffle 7 first contacts the external force and rotates slightly around the rotating shaft 6 to buffer the impact force and prevent the button 3 from being directly pressed. For example, when a feline jumps and its paw hits the switch, the rotational force-dissipating effect of the baffle 7 can prevent the button 3 from being triggered, preventing the living room lights or air conditioner from being turned on by mistake. The baffle 7 extends to the lower edge of the display screen 2. When the switch is accidentally bumped during furniture moving, the baffle 7 first contacts the obstacle and rotates, reducing the probability of the display screen 2 being directly impacted. Experimental data shows that after adding the baffle 7, the impact damage rate of the display screen 2 is reduced by more than 70%.

[0038] When the user needs to operate button 3, push the baffle 7 upward. The baffle 7 drives the limiting post 17 to move along the circular hole 18. When it rotates to 90°, the limiting post 17 falls into the placement hole 19. The first slider 15 rotates into position in the circular groove 13, and the baffle 7 is fixed in a vertical position, exposing button 3. At this time, the content of the display screen 2 can be clearly seen and button 3 can be pressed to complete the device control (such as adjusting the brightness of the light). After the operation is completed, rotate the baffle 7 downward. The limiting post 17 disengages from the placement hole 19. Under the torque of the first spring 8, the baffle 7 resets and covers button 3. At the same time, the limiting post 17 returns to its initial position, ensuring that the anti-accidental touch function remains effective. The whole operation process is smooth and can be completed with one hand, taking about 1.5 seconds.

[0039] When internal wiring needs to be inspected, pull the sliding plate 21 outward to move the limiting plate 22 out of the square groove 23 to overcome the resistance of the second spring 24 and expose the wiring port. The limiting shaft 26 keeps the limiting plate 22 in a stable position under the action of the third spring 29 to prevent it from completely detaching from the main body. After maintenance is completed, release the sliding plate 21 and the limiting plate 22 will reset under the action of the second spring 24 to cover the wiring gap and ensure that the protection level is restored to IP54.

[0040] Finally, see Figure 1 In this embodiment, the manual rotation of the baffle 7 is replaced by an electric push rod drive (such as a micro servo motor + gear transmission). The baffle 7 is automatically opened and closed by touch commands on the display screen 2. This is suitable for smart home systems and can be linked with voice assistants (such as when "turn on the anti-accidental touch mode", the baffle 7 automatically falls down to cover the button 3). The mechanical locking between the limiting post 17 and the placement hole 19 is replaced by a magnetic structure. A permanent magnet is installed at the end of the limiting post 17, and a ferrite magnetic sheet is set in the placement hole 19 to improve locking stability and reduce operating resistance, making it suitable for the elderly or children.

[0041] For switches used in high-risk areas (such as kitchens and bathrooms), the baffle 7 can be replaced with a metal material (such as 304 stainless steel) with an antibacterial coating to enhance impact and corrosion resistance. For ordinary scenarios, PC material is still used to balance cost and protection performance. The first spring 8 is replaced with a torsion spring with adjustable torque (range 0.5-1.2 N·m). The spring preload can be changed by adjusting the nut to adapt to the anti-accidental touch requirements of different usage environments (such as increasing the torque in high-flow public areas and decreasing the torque in home environments).

[0042] A pressure sensor is installed inside the baffle 7. When continuous external force is detected (such as a child pressing for a long time), an alarm is issued through the display screen 2 and the function of button 3 is temporarily locked to prevent accidental touch from causing danger (such as accidentally opening the gas valve). Three anti-accidental touch modes are set: "normally open" (baffle 7 is fixed and upright), "normal" (default protection), and "locked" (baffle 7 cannot be rotated). The menu on the display screen 2 can be switched to meet the needs of different scenarios (such as adjusting to the "locked" mode when there are pets at home).

[0043] Working principle:

[0044] When in use, the smart switch with anti-accidental touch function is normally in operation. The baffle 7 is attached to and covers the button 3 under the action of the first spring 8, forming a physical protective barrier. At this time, the adapter groove 9 on the baffle 7 corresponds to the position of the button 3. However, the weight of the baffle 7 and the spring force keep the baffle 7 in a closed state to prevent pets from colliding with it, children from accidentally touching it, or objects from falling and directly pressing the button 3.

[0045] The baffle 7 also covers the display screen 2. When the switch body 1 is subjected to an accidental impact (such as a furniture collision), the baffle 7 first contacts the external force and then dissipates the force through the rotating shaft 6, reducing the direct impact of the impact on the display screen 2.

[0046] When the user needs to operate button 3, the baffle 7 is manually pushed upwards. The baffle 7 rotates around the rotating shaft 6, compressing the first spring 8 and exposing button 3. At this time, the adapter slot 9 is fully aligned with button 3, making it convenient for the user to press button 3. When button 3 is pressed, the display screen 2 displays the corresponding operation interface (such as switching appliances on and off, adjusting brightness, etc.). After the operation is completed, the baffle 7 is released, and the baffle 7 automatically resets under the action of the first spring 8, covering button 3 again and restoring the anti-accidental touch state.

[0047] If the user needs to keep button 3 in an operable state for a long time (such as for frequent temporary use), the user can push the sliding column 14 to make the first slider 15 on the sliding column 14 slide in the first slide groove 12. At the same time, the connecting plate 16 and the limiting column 17 move downward. The limiting column 17 inserts into the round hole 18 on the baffle 7, and the connecting plate 16 falls into the placement hole 19. The baffle 7 is locked in the open state. At this time, button 3 is continuously exposed. There is no need to repeatedly move the baffle 7. Pull the sliding column 14 upward, the limiting column 17 disengages from the round hole 18, and the baffle 7 resets under the action of the first spring 8, covering button 3 again.

[0048] The limiting plate 22 on the side of the switch body 1, under the action of the second spring 24, by default blocks the interface (such as power cord interface, communication interface) connected to the outside world, preventing dust, foreign objects from entering or accidentally touching the interface and causing a short circuit. When it is necessary to connect the cable, manually pull the sliding plate 21 to drive the limiting plate 22 to compress the second spring 24 and expose the interface. After the connection is completed, release the sliding plate 21, and the limiting plate 22 will reset under the action of the second spring 24 and block the interface again. If it is necessary to connect the cable for a long time, the limiting shaft 26 can be inserted into the small hole 27 of the limiting plate 22, and the horizontal plate 28 presses down the third spring 29 to lock the limiting plate 22 in the open state to prevent the cable from loosening. After use, pull out the limiting shaft 26, and the limiting plate 22 will automatically reset.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
