Description
Technical Field
[0001] This utility model relates to the field of mobile terminal dustproof technology, and in particular to an industrial-grade dustproof mobile terminal. Background Technology
[0002] In the industrial sector, mobile terminals refer to portable electronic devices that can be used in factories and other work sites. These devices typically possess powerful data processing capabilities, durability, and various wireless communication functions, effectively supporting a wide range of industrial applications. They allow workers to access and process information in real time, facilitating real-time decision-making. The application of mobile terminals is becoming increasingly widespread, driving the digital transformation of production processes and helping enterprises achieve higher operational efficiency and cost savings.
[0003] In the existing technology, the design between the lower shell and the screen of the mobile terminal has obvious dustproof defects. This gap allows dust, fine particles and other impurities to easily penetrate into the device, which in turn negatively affects the touch performance of the screen and the function of internal components. After long-term use, the accumulated dust will not only cause the touch screen to be unresponsive and unresponsive, but may also lead to a decline in display effect. In severe cases, it may even cause device failure. In addition, this situation may also cause inconvenience to users when operating, reduce the overall user experience, and increase the maintenance cost of the device. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an industrial-grade dustproof mobile terminal.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: an industrial-grade dustproof mobile terminal, comprising a mobile terminal bottom shell, a mobile terminal screen fixed to the surface of the mobile terminal bottom shell, a mobile terminal volume button on one side of the mobile terminal bottom shell, a mobile terminal power button on one side of the mobile terminal bottom shell, a bottom microphone hole extending through the bottom of the mobile terminal bottom shell, a charging port extending through the bottom of the mobile terminal bottom shell, a top microphone hole extending through the top of the mobile terminal bottom shell, an inner shell support frame fixed to the inner wall of the mobile terminal bottom shell, a rubber sealing ring fixed to the surface of the inner shell support frame, and a support washer fixed to the surface of the inner shell support frame, the support washer being located inside the rubber sealing ring.
[0006] Preferably, the bottom of the mobile terminal's bottom shell has a through-hole for a bottom speaker, and the top of the mobile terminal's bottom shell has a through-hole for a top speaker. A dustproof mesh for the top speaker is fixed to the top of the inner wall of the mobile terminal's bottom shell, completely covering the top speaker hole. Similarly, a dustproof mesh for the bottom speaker is fixed to the bottom of the inside of the mobile terminal's bottom shell, completely covering the bottom speaker hole. In the prior art, the lack of dustproof measures for mobile terminal speakers allows dust and dirt to easily penetrate the speaker, leading to a decrease in sound quality, manifested as sound distortion and weakened bass, affecting the user's listening experience. Long-term accumulation of dust can also damage the speaker unit, causing the sound to become weak or produce noise, affecting the normal use of the device. Furthermore, fine particles in the external environment, such as sand and pollen, can accelerate speaker deterioration, increasing user maintenance costs. The lack of effective dustproof measures requires users to clean the speaker frequently, increasing the burden of use. To address these problems, this utility model adopts a dustproof structure covering the top of the mobile terminal. The dustproof mesh on the top and bottom of the mobile terminal speaker, located on one side of the speaker hole at the bottom, effectively prevents dust from entering, ensuring normal speaker operation. This significantly improves the sound quality and durability of the mobile terminal speaker, reduces the impact of dust and dirt on speaker performance, ensures clear sound and good bass, thereby enhancing the user's listening experience. Furthermore, these measures reduce the risk of speaker unit damage, lower equipment failure rates, alleviate the user's maintenance burden, save cleaning time and costs, and ultimately improve user satisfaction and brand loyalty, enhancing the product's competitiveness in the market.
[0007] Preferably, a mobile terminal battery heat dissipation back clip is fixed to the inner wall of the bottom shell of the mobile terminal. In the prior art, the battery of the mobile terminal generates heat during charging and discharging, and existing heat dissipation designs often cannot effectively dissipate this heat in a timely manner, resulting in excessively high battery temperature. This may not only affect the performance and battery life of the device, but also shorten the battery's lifespan, and even pose safety hazards in extreme cases. To address this problem, this utility model adopts a heat dissipation structure. The mobile terminal battery heat dissipation back clip located at the bottom of the battery can conduct the heat of the battery to the outer shell to a certain extent, thereby improving the heat dissipation effect and effectively reducing the battery temperature during charging and discharging. This ensures that the device operates stably in a high-performance state, which will significantly improve the device's battery life and overall performance, while extending the battery's lifespan and reducing safety hazards caused by overheating, thus providing users with a safer and more reliable user experience.
[0008] Preferably, a dustproof mesh for the earpiece is fixed to the surface of the mobile terminal's bottom shell. This dustproof mesh effectively prevents the intrusion of dust and impurities, protecting internal components such as the earpiece and extending the device's lifespan. It also ensures clear and stable call quality. This design enhances the device's functionality and durability, improves the user experience, and makes the mobile terminal more reliable in everyday use environments.
[0009] Preferably, the bottom shell of the mobile terminal features a frosted finish on both sides. This frosted finish not only improves grip comfort and slip resistance but also effectively reduces the appearance of fingerprints and smudges, making the device more aesthetically pleasing and easier to clean during daily use. This enhances the user experience and gives the device a more upscale appearance, reflecting meticulous craftsmanship and a sense of style.
[0010] Preferably, the aperture of the dustproof mesh for the top and bottom speakers of the mobile terminal is 0.5 mm to 0.8 mm. The dustproof mesh for the top and bottom speakers of the mobile terminal, with an aperture of 0.5 mm, effectively prevents dust and debris from entering the speaker interior without affecting sound quality and volume. This provides good acoustic performance while ensuring the durability and sound quality of the device, thus enhancing the user experience.
[0011] Preferably, a dust plug for the charging port is fixed to the bottom of the mobile terminal's casing, and the dust plug is embedded in the charging socket. This dust plug, embedded in the charging socket, effectively prevents dust and moisture from entering the charging port, thereby protecting the internal circuitry, extending the device's lifespan, and keeping the interface clean and intact when not in use for charging.
[0012] Beneficial effects:
[0013] 1. In existing technologies, the design between the lower casing and the screen of mobile terminals has obvious dustproof defects. This gap allows dust, fine particles, and other impurities to easily penetrate the device, negatively impacting the screen's touch performance and the functionality of internal components.

Furthermore, this situation can cause user inconvenience, reduce the overall user experience, and increase maintenance costs. To address these issues, this invention employs a sealed, dustproof support structure, significantly improving the device's touch performance and the normal operation of internal components, reducing the impact of dust and impurities, and extending the device's lifespan. Through improved design and materials, users can enjoy sensitive touch response and clear display effects even after prolonged use, reducing maintenance costs and enhancing the overall user experience, thus increasing user satisfaction.
[0014] 2. In existing technologies, the lack of dustproof measures in mobile terminal speakers allows dust and dirt to easily penetrate the speaker, leading to a decline in sound quality, manifested as sound distortion and weakened bass, affecting the user's listening experience. Long-term accumulation of dust can also damage the speaker unit, causing the sound to become weak or produce noise, affecting the normal use of the device. Furthermore, fine particles in the external environment, such as sand and pollen, can accelerate speaker deterioration, increasing user maintenance costs. The lack of effective dustproof measures necessitates frequent speaker cleaning, increasing the user's burden. To address these issues, this invention adopts a dustproof structure, significantly improving the sound quality and durability of the mobile terminal speaker, reducing the impact of dust and dirt on speaker performance, ensuring clear sound and good bass, thereby enhancing the user's listening experience. In addition, these measures can reduce the risk of speaker unit damage, lower the device failure rate, reduce the user's maintenance burden, save cleaning time and costs, ultimately improving user satisfaction and brand loyalty, and enhancing the product's competitiveness in the market.
[0015] 3. In existing technologies, mobile terminal batteries generate heat during charging and discharging, and current heat dissipation designs often fail to effectively dissipate this heat in a timely manner, leading to excessively high battery temperatures. This can not only affect device performance and battery life but also shorten battery lifespan and, in extreme cases, pose safety hazards. To address this issue, this utility model employs a heat dissipation structure to effectively reduce battery temperature during charging and discharging, ensuring stable operation of the device under high performance conditions. This will significantly improve the device's battery life and overall performance, while extending battery lifespan and reducing safety hazards caused by overheating, thereby providing users with a safer and more reliable user experience.

[0023] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:
[0026] Reference Figure 1-5An industrial-grade dustproof mobile terminal includes a mobile terminal bottom shell 1, a mobile terminal screen 101 fixed on the surface of the mobile terminal bottom shell 1, a mobile terminal volume button 102 and a mobile terminal power button 103 on one side of the mobile terminal bottom shell 1, a bottom microphone hole 111 and a charging port on the bottom of the mobile terminal bottom shell 1, a top microphone hole 112 through the top of the mobile terminal bottom shell 1, an inner shell support frame 2 fixed on the inner wall of the mobile terminal bottom shell 1, a rubber sealing ring 201 fixed on the surface of the inner shell support frame 2, and a support washer 202 fixed on the surface of the inner shell support frame 2, with the support washer 202 located inside the rubber sealing ring 201. In existing technologies, the design between the lower shell and the screen of mobile terminals has obvious dustproof defects. This gap allows dust, fine particles, and other impurities to easily penetrate into the device, negatively impacting the touch performance of the screen and the function of internal components. After prolonged use, accumulated dust can cause the touchscreen to become sluggish and unresponsive, and may also lead to a decline in display quality. In severe cases, it may even cause device malfunction. Furthermore, this situation can cause user inconvenience during operation, reduce the overall user experience, and increase device maintenance costs. To address these issues, this utility model adopts a sealed support dustproof structure, with a rubber sealing ring 201 and a support gasket 202 located above the inner shell support frame 2. The rubber sealing ring 201 provides a sealing and dustproof function, while the support gasket 202 provides support, preventing the rubber sealing ring 201 from deforming due to prolonged pressure, thus reducing the sealing effect.
[0027] The bottom of the mobile terminal's bottom shell 1 has a through-hole 107 for the bottom speaker, and the top of the mobile terminal's bottom shell 1 has a through-hole 106 for the top speaker. A dustproof net 108 for the top speaker is fixed to the top of the inner wall of the mobile terminal's bottom shell 1, which completely covers the top speaker hole 106. A dustproof net 109 for the bottom speaker is fixed to the bottom of the inside of the mobile terminal's bottom shell 1, which completely covers the bottom speaker hole 107. In the prior art, the lack of dustproof measures in mobile terminal speakers allows dust and dirt to easily penetrate the speaker, leading to a decrease in sound quality, manifested as sound distortion and weakened bass, affecting the user's listening experience. Long-term accumulation of dust may also damage the speaker unit, making the sound weak or producing noise, affecting the normal use of the device. In addition, fine particles in the external environment, such as sand and pollen, will also accelerate the deterioration of the speaker, increasing the user's maintenance costs. The lack of effective dustproof measures requires users to clean the speaker frequently, increasing the burden of use. To address these issues, this utility model adopts a dustproof structure, with a top speaker dustproof net 108 and a bottom speaker dustproof net 109 covering one side of the top speaker hole 106 and the bottom speaker hole 107 of the mobile terminal, which can block dust from entering to a certain extent, thereby ensuring the normal operation of the speaker.
[0028] A mobile terminal battery heat dissipation back clip 104 is fixed to the inner wall of the mobile terminal bottom shell 1. In the prior art, the mobile terminal battery generates heat during charging and discharging, and existing heat dissipation designs often cannot effectively dissipate this heat in a timely manner, resulting in excessively high battery temperature. This may not only affect the performance and battery life of the device, but also shorten the battery's lifespan, and even pose safety hazards in extreme cases. To address this problem, this utility model adopts a heat dissipation structure. The mobile terminal battery heat dissipation back clip 104 located at the bottom of the battery can conduct the heat of the battery to the outer shell to a certain extent, thereby improving the heat dissipation effect.
[0029] A dustproof mesh 105 for the earpiece is fixed to the surface of the mobile terminal's bottom shell 1. This mesh effectively prevents dust and impurities from entering, protecting internal components such as the earpiece and extending the device's lifespan. It also ensures clear and stable call quality. This design enhances the device's functionality and durability, improves the user experience, and makes the mobile terminal more reliable in everyday use. The sides of the mobile terminal's bottom shell 1 feature a frosted finish. This not only improves grip comfort and anti-slip properties but also effectively reduces fingerprints and smudges, making the device more aesthetically pleasing and easier to clean in daily use. This enhances the user experience and gives the device a more upscale appearance, reflecting meticulous craftsmanship and a sense of style. The dustproof mesh 108 for the top speaker and 109 for the bottom speaker have apertures ranging from 0.5 mm to 0.8 mm. The speaker dust filters 108 and 109 at the top and bottom of the mobile terminal feature a 0.5 mm aperture design, effectively preventing dust and debris from entering the speaker without affecting sound quality and volume. This provides excellent acoustic performance while ensuring device durability and sound quality, enhancing the user experience. A charging port dust plug 110 is fixed to the bottom of the mobile terminal's bottom casing 1, embedded within the charging port. This dust plug effectively prevents dust and moisture from entering the charging port, protecting the internal circuitry, extending the device's lifespan, and keeping the interface clean and intact when not charging.
[0030] The working principle of this utility model is as follows: The rubber sealing ring 201 and the support washer 202 are located above the inner shell support frame 2. The rubber sealing ring 201 plays a role in sealing and preventing dust, while the support washer 202 plays a supporting role, so that the rubber sealing ring 201 will not deform due to long-term pressure, thereby reducing the sealing effect. The dustproof nets 108 and 109 of the mobile terminal top speaker 106 and bottom speaker 107, which cover one side of the mobile terminal top speaker hole 106 and the mobile terminal bottom speaker 107, can block dust from entering to a certain extent, thereby ensuring the normal operation of the speaker. The mobile terminal battery heat dissipation back clip 104 located at the bottom of the battery can conduct the heat of the battery to the outer shell to a certain extent, thereby improving the heat dissipation effect.
