Description

Technical Field

[0001] This utility model relates to the field of display device technology, specifically to an intelligent waterproof display device designed for use in subway environments. Background Technology

[0002] In subway systems, display devices play a crucial role in showing passengers various information such as train operation information, route maps, and advertisements. However, existing subway display devices suffer from the following problems in practical applications:

[0003] The subway environment is complex, and water may accumulate on the platform, especially during heavy rain or when the drainage system fails. If the waterproof design of ordinary display devices is not good, water can easily seep into the interior, damaging electronic components, causing display abnormalities or even equipment failure, affecting the normal display of information, causing inconvenience to passengers, and increasing equipment maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent waterproof display device specifically designed for subway environments, in order to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] An intelligent waterproof display device specifically designed for subway environments, comprising:

[0007] The waterproof component includes a waterproof outer frame with a pair of support brackets mounted on its bottom surface. Several heat dissipation grooves are formed on the back of the waterproof outer frame. A heat dissipation component is installed inside the waterproof outer frame, and a drying component is slidably installed inside the waterproof outer frame, positioned between the heat dissipation grooves and the heat dissipation component. The display component includes a display screen embedded within the waterproof outer frame. A sealing gasket is provided between the side of the display screen and the waterproof outer frame. The waterproof outer frame serves as the outer shell of the entire device, preventing external moisture from directly contacting the display component and protecting the internal electronic components. The support brackets support the device. The function of the heat sink is to ensure that the device can be stably placed in the designated position; the heat dissipation channel provides a channel for heat dissipation, preventing the device from being damaged by overheating; the heat sink absorbs moisture that enters the waterproof outer frame, keeping the inside dry and further reducing the risk of moisture damage to electronic components; the heat sink can effectively reduce the internal temperature of the device, ensuring the normal operation of each component and extending the service life of the device; when installing the device, the support frame is placed on a suitable support surface to ensure the stability of the device; during the operation of the device, natural or forced heat dissipation is achieved through the heat sink and heat sink; when the heat sink needs to be replaced, it can be removed for handling or replacement by sliding the heat sink.

[0008] Furthermore, the drying component includes a storage box with several pores on its surface and an opening on its top surface. The storage box is filled with desiccant. The top surface of the waterproof outer frame has a slot, allowing the storage box to slide within the slot. The drying component also includes a fixing strip. Fixing blocks are installed on both sides of the storage box near its top surface, and the fixing strip and the fixing blocks are fixed with screws. The top surface of the waterproof outer frame has grooves on both sides of the slot, and the fixing blocks are located within these grooves. The fixing strip and the top surface of the slot are fixed with screws. The storage box is secured with screws, and the pores on its surface allow the desiccant to fully contact the air inside the waterproof frame, absorbing moisture. The openings facilitate the addition or replacement of the desiccant. The storage box slides within the slot for easy removal and installation. The combined use of fixing strips, fixing blocks, grooves, and screws ensures the storage box is firmly fixed within the waterproof frame, preventing shaking or displacement from affecting the drying effect. When the desiccant becomes saturated with moisture and needs replacement, first unscrew the fixing strips and the screws on the top surface of the slot, then slide the storage box out along the slot. Separate the fixing strips and fixing blocks, replace the desiccant, and then reinstall it in the reverse order.

[0009] Furthermore, the heat dissipation component includes a mounting bracket installed inside the waterproof outer frame. The mounting bracket has a pair of cooling fans on the side near the heat dissipation slot, and a pair of motors installed on the side near the display screen. The output end of the motors is connected to the cooling fans. The mounting bracket is used to install and fix the cooling fans and motors to ensure their stable operation. The motor drives the cooling fans to rotate, accelerating airflow and dissipating the heat generated inside the device through the heat dissipation slot, effectively reducing the internal temperature of the device, improving the heat dissipation efficiency of the device, ensuring that the display screen and other electronic components work in a suitable temperature environment, and extending the service life of the device. After the device is powered on, the motor starts and drives the cooling fans to rotate.

[0010] Furthermore, an ambient light sensor is installed on the front of the display screen, and a microprocessor and a wireless communication module are also installed inside the display screen. The ambient light sensor can detect the intensity of the surrounding ambient light, and the microprocessor automatically adjusts the brightness of the display screen based on the detection data of the ambient light sensor after conversion by the analog-to-digital converter. This ensures that passengers can clearly see the displayed content, saves energy, and extends the life of the display screen. The wireless communication module enables the display screen to receive information from external devices, enabling real-time updates and ensuring that passengers have access to the latest information. The ambient light sensor and the wireless communication module operate automatically after the device is powered on, without manual intervention. The microprocessor continuously receives data from the ambient light sensor and adjusts the brightness of the display screen according to a preset program. The wireless communication module receives external information periodically or in real-time according to a pre-set communication protocol and transmits it to the microprocessor for processing and display.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This intelligent waterproof display device, specifically designed for subway environments, effectively prevents moisture damage to the display device through the synergistic effect of a waterproof frame, sealing gasket, and drying component. The waterproof frame, as the primary line of defense, blocks external moisture from directly contacting the display components, significantly reducing the risk of damage to electronic components due to water ingress. The sealing gasket between the display screen and the waterproof frame further enhances waterproof performance, preventing moisture from seeping in through gaps. The storage box in the drying component is filled with desiccant, and its surface pores allow the desiccant to fully contact the internal air, absorbing moisture entering the waterproof frame and maintaining a dry internal environment. This provides comprehensive protection for electronic components, reducing malfunctions caused by moisture and extending the device's lifespan. The heat dissipation groove and heat sink work together to provide efficient heat dissipation. The heat dissipation groove provides a convenient channel for heat dissipation, and the motor-driven cooling fan accelerates airflow, quickly expelling heat generated inside the device through the heat dissipation groove, effectively reducing the internal temperature. This ensures that the display screen and other electronic components always operate in a suitable temperature environment, avoiding performance degradation or damage due to overheating, further guaranteeing the stability and reliability of the device.

Detailed Implementation

[0017] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an intelligent waterproof display device specifically designed for subway environments, comprising the following steps:

[0018] A typical subway platform was selected as the test point. Based on the platform's layout and design requirements, the device was stably placed in a suitable location on the platform using support frame 1002, ensuring the device was securely installed and did not obstruct passenger passage. During installation, the waterproof outer frame 1001 was kept horizontal. The display screen 2001, motor 1005, ambient light sensor 2002, wireless communication module, and other equipment were connected to their respective power supplies and control lines. The connection process strictly adhered to electrical safety regulations, ensuring correct and secure wiring connections to prevent malfunctions caused by loose wiring or short circuits. The storage box 1007 was slidably installed within the slot 1010 of the waterproof outer frame 1001. The storage box 1007 already contained... After filling with desiccant, align the fixing block 1009 with the groove 1011 and use screws to fix the fixing strip 1008 to the waterproof outer frame 1001, ensuring the storage box 1007 is securely installed. Analyze and process the data from the ambient light sensor 2002 using a microprocessor, setting an appropriate brightness adjustment threshold. For example, when the ambient light intensity is below a certain value, the display screen 2001 automatically reduces its brightness; when the ambient light intensity is above a certain value, the display screen 2001 automatically increases its brightness to ensure passengers can clearly see the displayed content under different lighting conditions. Configure the communication parameters of the wireless communication module to establish a stable connection with the subway operation management system server. Set the information update frequency to ensure the display screen 2001 can receive and display the latest train operation information, route maps, etc., in real time. Start the motor 1005 and check the rotation of the cooling fan 1006 to ensure it is operating normally and effectively dissipating internal heat through the heat dissipation slot 1003. Adjust the speed of the cooling fan 1006 to achieve optimal heat dissipation.

[0019] Specifically, the working principle of this intelligent waterproof display device specifically designed for subway environments is as follows: The waterproof outer frame 1001 serves as the outer shell of the device, providing the first layer of protection for the internal electronic components and preventing external moisture from directly contacting the display element 200. The sealing gasket between the display screen 2001 and the waterproof outer frame 1001 further enhances the waterproof effect, preventing moisture from seeping in through gaps. The storage box 1007 in the drying component is filled with desiccant. The pores on the surface of the storage box 1007 allow the desiccant to fully contact the air inside the waterproof outer frame 1001, absorbing the incoming moisture and keeping the interior dry. When the desiccant in the storage box 1007 becomes saturated with moisture, it can be removed by sliding the storage box 1007 to replace the desiccant, ensuring the continuity of the drying effect and comprehensively reducing the risk of moisture damage to the electronic components. During device operation, the electronic components generate heat. After the motor 1005 in the heat sink starts, it drives the cooling fan 1006 to rotate. The fixing bracket 1004 supports and fixes the motor 1005 and the cooling fan 1006, ensuring their stable operation. The rotation of the cooling fan 1006 causes rapid airflow, transferring the heat inside the device to the heat sink 1003, and then exhausting it to the external environment through the heat sink 1003. This effectively reduces the internal temperature of the device, ensuring that the display screen 2001 and other electronic components work normally in a suitable temperature environment, avoiding performance degradation or damage due to overheating, and extending the service life of the device.
