[0050] Display devices are an important component of information technology and consumer electronics. Also known as monitors, displays, or screens, they are devices that output images or tactile information. Display devices include light-emitting diode (LED) displays, liquid crystal displays (LCDs), and organic light-emitting diode (OLED) displays.

[0051] As a type of display device, the voice-activated smart screen integrates multiple interactive modes such as audio-visual, fitness, and education, and features voice control functionality. Users can control smart home devices, such as lights, air conditioners, and curtains, via voice commands; they can also operate the smart screen through the touchscreen, such as browsing information, selecting functions, and adjusting settings. As a home consumer electronics product, the IP (Ingress Protection) rating of the voice-activated smart screen is particularly important. Under alternating hot and cold temperatures, the display screen is prone to water droplets or condensation. In humid environments, prolonged use can lead to dust accumulation, which, in a damp environment, can easily cause oxidation of the metal terminals of electronic components.

[0052] Among related technologies, voice-activated smart screens have poor waterproof and dustproof performance, which can easily cause circuit failures and lead to electrical safety accidents.

[0053] refer to Figure 1 , Figure 2 and Figure 3 This application provides a smart screen, including a front cover 100, a screen 200, and a mounting cover 300.

[0054] The front shell 100 serves as the outer casing of the smart screen, supporting the screen 200 and protecting the internal components. Various interfaces and buttons can also be designed on the front shell 100, such as a power interface, volume control buttons, and a menu button, for convenient user operation and control.

[0055] The screen 200 is connected to the front cover 100, and the screen 200 can be mounted on a wall or placed on a desktop through the front cover 100.

[0056] Optionally, screen 200 is equipped with a touchscreen, making the use of the smart screen more intuitive and efficient. Users can perform various operations, such as changing channels, adjusting volume, and browsing the internet, by swiping, clicking, and pinching their fingers on screen 200.

[0057] The mounting cover 300 and the screen 200 are spaced apart. The front shell 100 is connected between the screen 200 and the mounting cover 300. The inner wall of the front shell 100, the side of the screen 200 facing the mounting cover 300, and the side of the mounting cover 300 facing the screen 200 form a receiving cavity 110. The receiving cavity 110 can be used to accommodate electrical components 400, etc. A first sealing member 500 is provided at the connection position between the front shell 100 and the screen 200, and a second sealing member 600 is provided at the connection position between the front shell 100 and the mounting cover 300.

[0058] The first sealing element 500 can be silicone, foam, rubber, EVA (ethylene-vinyl acetate copolymer) sealing strip, etc., and there are no specific restrictions.

[0059] The second sealing element 600 can be silicone, foam, rubber, EVA (ethylene-vinyl acetate copolymer) sealing strip, etc., and there are no specific restrictions.

[0060] The smart screen provided in this application embodiment connects the front shell 100 between the screen 200 and the mounting cover 300, so that the inner wall of the front shell 100, the side of the screen 200 facing the mounting cover 300, and the side of the mounting cover 300 facing the screen 200 form a receiving cavity 110. The receiving cavity 110 can accommodate electrical components 400 and other parts. A first sealing element 500 is provided at the connection position between the front shell 100 and the screen 200, and a second sealing element 600 is provided at the connection position between the front shell 100 and the mounting cover 300, thereby forming a closed receiving cavity 110. This can effectively prevent dust, moisture, and other external substances from entering the interior of the smart screen, thereby extending the service life and reliability of electrical components 400 and other parts, suppressing circuit failures, and ensuring electrical safety.

[0061] refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The front cover 100 includes a first through hole 120 and a mounting surface 130. The mounting surface 130 is located at one end of the first through hole 120 and is the surface of the front cover 100 facing the user. A first sealing member 500 is disposed on the mounting surface 130, and a second sealing member 600 is disposed on the hole wall of the first through hole 120. By providing the first sealing member 500 on the mounting surface 130 of the first through hole 120 and the second sealing member 600 on the hole wall of the first through hole 120, a double sealing effect is achieved, thereby sealing both ends of the first through hole 120 to form a closed receiving cavity 110. This can more effectively prevent external impurities such as moisture and dust from entering the receiving cavity 110, thereby protecting the screen 200 and its internal electrical components 400.

[0062] The use of the first seal 500 and the second seal 600 can reduce the risk of damage to the screen 200 or performance degradation caused by the intrusion of external impurities. At the same time, the first seal 500 and the second seal 600 can also provide a certain degree of cushioning and protection, reducing damage to the screen 200 caused by external impacts or vibrations.

[0063] In one embodiment, a groove 131 is provided on the mounting surface 130, surrounding the first through hole 120. The first sealing member 500 is filled in the groove 131 and is tightly connected to the screen 200. The design of the groove 131 allows the first sealing member 500 to fit more tightly on the mounting surface 130, reducing the risk of the first sealing member 500 loosening or falling off. The tight connection between the first sealing member 500 and the screen 200 further enhances the sealing effect between the screen 200 and the front shell 100, effectively preventing external impurities such as moisture and dust from entering the interior of the screen 200. The design of the groove 131 provides a clear positioning for the installation of the first sealing member 500, simplifying the installation process. Furthermore, the combination design of the groove 131 and the first sealing member 500 can form a smooth transition, making the smart screen look cleaner and more aesthetically pleasing.

[0064] Optionally, the first seal 500 is an adhesive. The adhesive has excellent adhesion and sealing properties, allowing it to adhere tightly to the mounting surface 130, forming an effective sealing barrier. The groove 131 has a certain width and depth to accommodate a certain amount of adhesive. During assembly, waterproof sealing adhesive is injected into the groove 131, and the screen 200 is assembled with the front housing 100 using a tooling fixture. Pressure is maintained for a certain period to allow the adhesive to fully cure, achieving the best sealing effect. This seal is non-removable. This ensures a relatively sealed space between the front housing 100 and the screen 200, effectively preventing water droplets, condensation, vapor, etc., from damaging the screen 200 and ensuring the electrical safety of the electrical components 400 within the housing cavity 110.

[0065] In one embodiment, the second seal 600 is interference-fitted with the first through hole 120. This interference fit increases the friction between the second seal 600 and the first through hole 120, making the seal more securely fixed in the through hole. This helps reduce the risk of the second seal 600 loosening or falling off due to vibration or external impact, improving the overall stability of the smart screen.

[0066] The second seal 600 is provided with a guide slope 610. In the extending direction of the first through hole 120, the cross-sectional area of ​​the second seal 600 gradually decreases from the end furthest from the mounting surface 130 to the end closest to the mounting surface 130. The design of the guide slope 610 makes it easier for the second seal 600 to enter the first through hole 120 during installation. As the second seal 600 moves along the extending direction of the first through hole 120, the end of the second seal 600 furthest from the mounting surface 130 will experience greater compressive force, which helps to increase the contact area and contact pressure between the second seal 600 and the first through hole 120, thereby improving sealing performance. Simultaneously, the second seal 600 with the guide slope 610 can better adapt to first through holes 120 of different sizes and shapes, improving the adaptability and flexibility of the second seal 600.

[0067] In one embodiment, a raised rib 310 is provided on the surface of the mounting cover 300 facing the screen 200, and the raised rib 310 is embedded in the second sealing member 600. The raised rib 310 embedded in the second sealing member 600 forms a tighter contact surface, which helps to reduce the gap between the second sealing member 600 and the mounting cover 300, thereby improving sealing performance. The interference fit between the raised rib 310 and the second sealing member 600 forms an effective waterproof wall. This effectively prevents moisture, dust, etc., from entering the electrical components 400 inside the receiving cavity 110 from the wall, ensuring the electrical safety of the electrical components 400.

[0068] Optionally, the height of the rib 310 protruding from the surface of the mounting cover 300 ranges from 0.1mm to 0.5mm. Under this size limitation, the rib 310 can not only form a better sealing effect with the second seal 600, but also suppress the excessive deformation of the second seal 600, resulting in a smaller contact area between the second seal 600 and the surface of the mounting cover 300.

[0069] refer to Figure 7 and Figure 8 The smart screen also includes an electrical component 400 and a third seal 700. The electrical component 400 is housed in a receiving cavity 110 and is connected to the screen 200. The electrical component 400 has a data port 410, and the third seal 700 is detachably fitted onto the data port 410. The design of the third seal 700 provides an additional protective barrier for the data port 410 of the electrical component 400, preventing moisture, dust, and other contaminants from entering the data port 410 and the interior of the electrical component 400, thereby extending the service life and reliability of the electrical component 400. Furthermore, since the third seal 700 is detachable, users can choose whether to install it based on different usage scenarios and needs.

[0070] The data port 410 can be USB Type-A, USB Type-B, USB Type-C, etc., and there are no specific restrictions.

[0071] The mounting cover 300 has a second through hole 320 communicating with the receiving cavity 110. The second through hole 320 is positioned opposite to the data port 410, and a third sealing member 700 is inserted into the second through hole 320. The second through hole 320 is provided for the data port 410 to connect to external devices. The insertion of the third sealing member 700 into the second through hole 320 effectively prevents dust and moisture from entering the receiving cavity 110 and the data port 410 through the second through hole 320, thereby protecting the electronic components and data connections inside the smart screen from damage.

[0072] refer to Figure 8 , Figure 9 and Figure 10 The smart screen also includes a rear shell 800 and a fourth sealing element 900. The rear shell 800 is connected to a mounting cover 300, and the mounting cover 300 has a third through hole 330 connecting the receiving cavity 110 and the rear shell 800. The electrical component 400 has a pin header 420, which is inserted into the third through hole 330. The rear shell 800 has a nut header 810, in which the pin header 420 is inserted. The fourth sealing element 900 is fitted onto the nut header 810 and covers the end of the third through hole 330 near the rear shell 800. By setting the pin header 420 on the electrical component 400 and inserting it into the third through hole 330, the pin header 420 and the nut header 810 on the rear shell 800 form an electrical connection, which is easy to install and disassemble, while ensuring the stability and accuracy of the electrical connection. The fourth sealing element 900 is fitted onto the nut 810 and covers the end of the third through hole 330 near the rear shell 800, forming an additional sealing layer. This effectively prevents external foreign objects such as dust and moisture from entering the smart screen through the third through hole 330, protecting the electrical components 400 and data connections from damage.

[0073] A partition 820 can be installed between the mounting cover 300 and the rear shell 800. The mounting cover 300 and the partition 820 have an interlocking structure with concave and convex shapes, which increases the flow resistance of air and moisture. The fourth sealing element 900 is stepped, with one step pressed by the partition 820 and the other step pressed by the mounting cover 300, effectively preventing water droplets and moisture from entering the receiving cavity 110 through the gap between the nut 810 and the pin 420, thus ensuring the electrical safety of the smart screen.

[0074] In one embodiment, one of the front shell 100 and the rear shell 800 is provided with a buckle 140, and the other of the front shell 100 and the rear shell 800 is provided with a slot, in which the buckle 140 is engaged. Specifically, the smart screen can be mounted on a wall using the rear shell 800; after the rear shell 800 is installed, the design of the buckle 140 and the slot allows the front shell 100 and the rear shell 800 to be quickly and easily connected together without the need for additional fasteners (such as screws) or complex assembly processes, reducing assembly difficulty and time costs.

[0075] The smart screen provided in this application features a multi-directional structural sealing design, including between the front shell 100 and the screen 200, between the front shell 100 and the mounting cover 300, at the data port 410, and at the connection points of the pin header 420 and the nut header 810. This effectively prevents water droplets and moisture from entering the housing 110, ensuring the electrical safety of the electrical components 400, improving the smart screen's waterproof, dustproof, and moisture-proof performance, and increasing the product's lifespan.
