Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of display modules, and more specifically, to a module structure with a waterproof function. Background Art
[0002] With the rapid development of automotive electronic technology, in-vehicle modules, as the core components of automotive intelligence and informatization, have an increasingly wide range of applications, covering multiple fields such as in-vehicle infotainment systems, navigation systems, safety assistance systems, and autonomous driving. These modules not only require high performance and high reliability but also must be able to adapt to various complex and changeable usage environments, including extreme temperatures, vibrations, dust, and most critically, the water vapor environment.
[0003] The existing design structures of in-vehicle modules often seem inadequate when dealing with the water vapor environment. Traditional in-vehicle module designs are usually assembled from components such as a cover plate, a TFT display screen, and a backlight module. Among them, the electronic components on the FPC (flexible printed circuit board) and PCB (printed circuit board) are directly exposed without effective waterproof protection measures. This design may be able to work properly in dry or controlled environments, but once it enters an environment rich in water vapor, such as rainy days, car washing, or wading driving, water vapor may invade the interior of the module through gaps or interfaces, causing damage to the electronic components, TFT circuits, and backlight module. The moisture absorption of electronic components may lead to short circuits, corrosion, or performance degradation, thereby affecting the overall function of the module. The damage to the TFT circuit may cause problems such as screen flickering, black screen, or abnormal display on the display screen, seriously affecting the driver's usage experience. In addition, the accumulation of water inside the backlight module may also cause uneven light effects, brightness reduction, or complete failure, further reducing the display effect. Therefore, we make improvements in this regard and propose a module structure with a waterproof function. Summary of the Utility Model

[0025] As described in the background art, the design structure of existing in-vehicle modules often proves inadequate when dealing with a water vapor environment. Traditional in-vehicle module designs are typically assembled from components such as a cover plate, a TFT display screen, and a backlight module. Among them, the electronic components on the FPC (flexible printed circuit board) and PCB (printed circuit board) are directly exposed without effective waterproof protection measures. This design may be able to work properly in a dry or controlled environment, but once it enters an environment rich in water vapor, such as rainy days, car washes, or wading driving, water vapor may invade the interior of the module through gaps or interfaces, causing damage to the electronic components, TFT circuits, and backlight module; the moisture absorption of electronic components may lead to short circuits, corrosion, or performance degradation, thereby affecting the overall function of the module. The damage to the TFT circuit may cause problems such as a flower screen, a black screen, or abnormal display on the display screen, seriously affecting the driving experience of the driver. In addition, the accumulation of water inside the backlight module may also cause uneven light effects, brightness reduction, or complete failure, further reducing the display effect.
[0026] To solve this technical problem, this utility model provides a module structure with a waterproof function.
[0027] Specifically, please refer to Figures 1 - 4 , the module structure with a waterproof function specifically includes:
[0028] A display module main body 1, the display module main body 1 has an FPC main body 101, the display module main body 1 is connected with a waterproof shell 2, a protruding end 206 is arranged on one side of the waterproof shell 2 away from the display module main body 1, a wire passing port 201 is arranged at the protruding end 206, the FPC main body 101 passes through the wire passing port 201, and a sealing part is arranged at the FPC main body 101 and the protruding end 206.
[0029] The module structure with waterproof function provided by the present utility model. In this application, by setting a waterproof shell 2 on the display module main body 1, a sealed environment can be formed. The waterproof structure design improves the stability and reliability of the module in harsh environments, extends the service life of the module. By effectively isolating water vapor, this design reduces problems such as short circuits and corrosion caused by humid environments, and extends the service life of the module. At the same time, the sealing structure can also resist the intrusion of other pollutants such as dust and particulate matter to a certain extent, further protecting the cleanliness inside the module.
[0030] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.
[0031] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.
[0032] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0033] Embodiment 1 of the module structure with waterproof function of the present utility model
[0034] Please refer to Figures 1 - 4 , the module structure with waterproof function of the present utility model includes: a display module main body 1, the display module main body 1 has an FPC main body 101, the display module main body 1 is connected with a waterproof shell 2, a protruding end 206 is arranged on the side of the waterproof shell 2 away from the display module main body 1, a wire passing hole 201 is arranged at the protruding end 206, the FPC main body 101 passes through the wire passing hole 201, and a sealing part is arranged at the FPC main body 101 and the protruding end 206. In this application, by setting a waterproof shell 2 on the display module main body 1, a sealed environment can be formed. The waterproof structure design improves the stability and reliability of the module in harsh environments, extends the service life of the module. By effectively isolating water vapor, this design reduces problems such as short circuits and corrosion caused by humid environments, and extends the service life of the module. At the same time, the sealing structure can also resist the intrusion of other pollutants such as dust and particulate matter to a certain extent, further protecting the cleanliness inside the module.
[0035] Further, as Figure 1 and Figure 3As shown, the display module main body 1 includes a cover plate main body 104. A double-sided adhesive main body 205 is connected between the FPC main body 101 and the waterproof shell 2. Through the double-sided adhesive main body 205, the cover plate main body 104 and the waterproof shell 2 can be connected together. Using the double-sided adhesive main body 205 to connect the cover plate main body 104 and the waterproof shell 2 enhances the connection stability and sealing performance between the two. This tight connection can prevent water vapor and dust from penetrating into the module interior from the connection part, ensuring the protection effect of the module. At the same time, the stable connection also reduces the loosening of components caused by vibration or external force, improving the overall structural strength and durability of the module. For example, during transportation or use, even if it is jolted or impacted, it can maintain a good sealing state to protect the internal components from damage.
[0036] Further, as Figure 1 and Figure 3 shown, the cover plate main body 104 is connected with a backlight assembly 103. A TFT module 102 is arranged between the cover plate main body 104 and the backlight assembly 103. One end of the FPC main body 101 is connected with the TFT module 102, and the other end of the FPC main body 101 passes through the backlight assembly 103. Such a structural layout is reasonable, and each component cooperates with each other to achieve an efficient display function.
[0037] Embodiment 2 of the module structure with waterproof function of the present utility model
[0038] Further of the module structure with waterproof function of the present utility model, as Figure 1 and Figure 2 shown, the sealing part includes a sealing cover 202 located on the side of the protruding end 206 away from the waterproof shell 2. A fastening bolt 203 is connected between the sealing cover 202 and the protruding end 206, and the FPC main body 101 passes through between the protruding end 206 and the sealing cover 202. The sealing cover 202 can seal the protruding end 206 and can clamp and fix the FPC main body 101. The design of the sealing cover 202 and the fastening bolt 203 can, on the one hand, ensure the sealing performance of the protruding end 206 to prevent external water vapor and impurities from entering here, and on the other hand, the clamping and fixing of the FPC main body 101 avoids its shaking or displacement during use, reducing signal transmission problems caused by unstable connection. For example, in some environments with frequent vibrations, such as in-vehicle devices, it can ensure the stable connection between the FPC main body 101 and other components, ensuring the normal operation of the display module.
[0039] Further, as Figure 1As shown, a first seal is provided between the protruding end 206 and the sealing cover 202. The first seal can improve the sealing performance at the connection between the sealing cover 202 and the protruding end 206, thereby enhancing the sealing between the FPC main body 101, the sealing cover 202, and the protruding end 206. This effectively prevents the penetration of tiny water vapor and dust, providing more reliable protection for the FPC main body 101. Even during long-term use or in extreme environments, a good sealing effect can be maintained. For example, in a high-humidity environment, the first seal can ensure that the interior of the module always remains dry and prevent the FPC main body from being damaged by moisture.
[0040] Furthermore, as Figure 1 shown, the first seal includes two first sealing rings 204 disposed between the protruding end 206 and the sealing cover 202. The two first sealing rings 204 are respectively located on both sides of the FPC main body 101. The first sealing ring 204 can improve the sealing between the FPC main body 101, the sealing cover 202, and the protruding end 206. The two first sealing rings 204 are located on both sides of the FPC main body 101 respectively, forming a double protection, greatly enhancing the reliability of the seal. Even if one of the sealing rings shows slight aging or damage, the other sealing ring can still play an effective sealing role. This double guarantee is particularly important in some occasions with extremely high sealing requirements, such as equipment working underwater or electronic equipment exposed to strong wind and rain environments, which can effectively extend the service life of the module and reduce the number of repairs.
[0041] Embodiment Three of the Module Structure with Waterproof Function of the Present Utility Model
[0042] Furthermore, as Figure 3 shown, the sealing part includes a vehicle-mounted housing 3 sleeved on the outer surface of the protruding end 206. The FPC main body 101 passes through the protruding end 206 and extends into the vehicle-mounted housing 3 and Figure 4 inside. Such a setting makes a sealed environment formed between the waterproof housing 2 and the vehicle-mounted housing 3 to reduce the entry of water vapor, further strengthening the protection of the entire module. This not only reduces the entry of water vapor but also can resist external physical impacts.
[0043] Furthermore, as Figure 3 shown, a second seal is provided on the outer surfaces of the waterproof housing 2 and the protruding end 206. The second seal can improve the sealing performance at the connection between the waterproof housing 2 and the vehicle-mounted housing 3, effectively preventing the penetration of water vapor and dust from this connection. This is crucial for equipment that is in a complex environment for a long time, ensuring that the module still maintains good performance under harsh conditions. For example, in a dusty construction site environment or a humid coastal area, the second seal can protect the interior of the module from being eroded by the external environment and extend the service life of the equipment.
[0044] Further, as Figure 3 shown, a second sealing ring 4 is provided at the inner wall of the vehicle-mounted housing 3. The inner wall of the second sealing ring 4 contacts the outer surface of the protruding end 206. The setting of the second sealing ring 4 can improve the sealing performance at the connection between the waterproof housing 2 and the vehicle-mounted housing 3.
[0045] Further, as Figure 3 shown, a limiting groove 5 is formed on the outer surface of the protruding end 206. The second sealing ring 4 is inserted into the inner wall of the limiting groove 5. The limiting groove 5 can limit the second sealing ring 4 and reduce the movement of the second sealing ring 4, so that the second sealing ring 4 can always remain in the best sealing position, providing continuous and reliable protection for the module. For example, when the device vibrates frequently or is impacted by external forces, the limiting groove 5 can ensure that the second sealing ring 4 does not get out of position, thus maintaining good sealing performance.
[0046] Obviously, the embodiments described above are only a part of the embodiments of the present invention, rather than all of them. The accompanying drawings show the preferred embodiments of the present invention, but do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present invention more thorough and comprehensive. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or perform equivalent replacements on some of the technical features. Any equivalent structure directly or indirectly using the content of the specification and drawings of the present invention in other related technical fields is equally within the scope of the patent protection of the present invention.
