Description

Technical Field

[0001] This utility model relates to the field of silicone protective cases for mobile phones, specifically a rubber pad mechanism for mobile phones. Background Technology

[0002] Silicone pads for mobile phones are protective materials designed specifically for electronic devices. They are mainly made of high-molecular elastomers and have flexibility, impact resistance, and abrasion resistance. They can effectively absorb external impacts and reduce damage to mobile phones.

[0003] Regarding the aforementioned technologies, there are certain shortcomings in their use: Currently, mobile phones are highly protected, typically with a silicone protective case covering the outer shell to prevent accidental drops and mitigate wear and tear during daily use. Multiple small holes are located at the bottom of the phone, corresponding to the noise-canceling microphone and speaker modules inside. To ensure their functionality, openings are provided in the corresponding locations on the silicone protective case. However, with continuous use, external dust can enter the small holes containing the noise-canceling microphone and speaker through these openings, causing blockages and affecting functionality. Currently, mobile phone protective cases have not addressed this defect.

[0004] Therefore, this utility model provides a rubber pad mechanism for mobile phones to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a rubber pad mechanism for mobile phones, which solves the above problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a rubber pad mechanism for mobile phones, including a mobile phone shell made of thermoplastic polyurethane, and dustproof components are provided on the bottom wall of the mobile phone shell at positions corresponding to the mobile phone microphone, speaker and charging port. The dustproof component includes openings on both sides of the bottom wall of the phone casing. Limiting grooves are provided on the bottom wall of the phone casing at the positions corresponding to the upper and lower sides of the openings. Limiting rings are provided on the inner walls of the limiting grooves. The same mounting ring is fixedly installed between the two limiting rings on the same side. The outer wall of the mounting ring fits against the inner wall of the opening. A dustproof mesh is fixedly installed on the inner wall of the mounting ring to prevent external dust from entering the microphone and speaker modules of the phone through the openings. The bottom wall of the phone casing is squeezed to cause overall deformation. The limiting rings, mounting rings, and dustproof mesh are removed from the openings for regular cleaning. The limiting rings and mounting rings are made of silicone.

[0007] The above technical solution mainly involves dustproofing the bottom of the microphone and speaker on the phone casing to prevent dust from entering the microphone and speaker and causing module malfunction.

[0008] Furthermore, a passage is provided on the bottom wall of the phone casing at the position corresponding to the phone charging port. An installation groove is provided on the inner wall of the passage, and a dust cover with an internal cavity is hinged to the inner wall of the installation groove.

[0009] The dust cover hinged to the inner wall of the mounting groove, as described above, can seal the location of the mobile phone charging port and prevent external dust from entering.

[0010] Furthermore, the dust cover is smaller than the phone charging port, and the outer wall of the dust cover fits snugly against the inner wall of the phone charging port, preventing external dust from entering and causing poor contact of the charging interface terminals. An insertion opening is provided at the front of the bottom wall of the port, making it easy to pry the dust cover out from the opening with your fingers.

[0011] The above technical solution provides an insertion port at the front of the bottom wall of the passage, making it easy to pry the dust cover out of the passage with your fingers, which is convenient for daily use.

[0012] Furthermore, the four corners of the inner wall of the phone case are rounded to match the outer edge of the corresponding phone model. A positioning ring is fixedly installed at the front of the inner wall of the phone case. The positioning ring limits the position of the outer edge of the phone screen placed inside the phone case to prevent it from falling off.

[0013] Through the above technical solution, the positioning ring limits the position of the mobile phone screen placed inside the mobile phone casing to prevent assembly from falling off, thereby improving the stability of the mobile phone assembly.

[0014] Furthermore, the back wall of the phone case has ventilation holes for heat dissipation, and the top of the back wall of the phone case has an outward protrusion for accommodating the phone's camera.

[0015] The above technical solutions enable the design of heat dissipation holes to assist in heat dissipation and improve heat exchange efficiency in mobile phones.

[0016] Furthermore, one side of the phone case has a receiving groove for accommodating the phone's power button, and the other side of the phone case has a receiving groove for accommodating the phone's volume buttons. The back wall of the phone case is evenly covered with anti-slip protrusions to increase friction with the hand and enhance grip stability.

[0017] The above technical solution provides a storage slot 1 and a storage slot 2 for storing the power button and volume buttons of a mobile phone. Beneficial effects

[0018] This invention provides a rubber pad mechanism for mobile phones. Compared with the prior art, it has the following advantages: (1) The rubber pad mechanism for mobile phones can seal or prevent dust from entering the corresponding positions of the mobile phone microphone, speaker and charging port through the setting of the dustproof component. This can prevent external dust from entering during normal use and causing abnormalities in the microphone and speaker modules, increase the protection of the mobile phone and further optimize the defects and deficiencies of the mobile phone protective case.

[0019] (2) The rubber pad mechanism for mobile phones, by opening heat dissipation holes in the mobile phone shell, allows the heat generated when the mobile phone is working to dissipate outward from the heat dissipation holes, thereby improving the heat exchange efficiency and creating a cooling effect on the mobile phone. Anti-slip protrusions are set on the back wall of the mobile phone shell to increase friction with the hand and grip stability, preventing the mobile phone from slipping during daily use.

Detailed Implementation

[0022] 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.

[0023] Example 1: Please refer to Figures 1-5 A rubber pad mechanism for mobile phones includes a mobile phone housing 1 made of thermoplastic polyurethane, and dustproof components 8 are provided on the bottom wall of the mobile phone housing 1 and at positions corresponding to the mobile phone microphone, speaker and charging port. The dustproof component 8 includes openings 82 on both sides of the bottom wall of the phone housing 1. Limiting grooves 81 are provided on the bottom wall of the phone housing 1 at the positions corresponding to the upper and lower sides of the openings 82. Limiting rings 84 are provided on the inner walls of the limiting grooves 81. The same mounting ring 83 is fixedly installed between the two limiting rings 84 on the same side. The outer wall of the mounting ring 83 fits against the inner wall of the opening 82. A dustproof mesh 85 (a mesh structure with small aperture) is fixedly installed on the inner wall of the mounting ring 83 to prevent external dust from entering the microphone and speaker modules of the phone through the openings 82. When the bottom wall of the phone housing 1 is squeezed, the overall deformation occurs, and the limiting rings 84, mounting rings 83 and dustproof mesh 85 are removed from the openings 82 for regular cleaning. The limiting rings 84 and mounting rings 83 are both made of silicone. The bottom wall of the phone casing 1 has a through-hole 86 corresponding to the position of the phone charging port. The inner wall of the through-hole 86 has a mounting groove 89. A dust cover 87 with an internal cavity is hinged to the inner wall of the mounting groove 89. The dust cover 87 is smaller than the phone charging port, and the outer wall of the dust cover 87 fits against the inner wall of the phone charging port to prevent external dust from entering and causing poor contact of the charging interface terminal. An insertion hole 88 is provided at the front of the bottom wall of the through-hole 86 to facilitate the removal of the dust cover 87 from the through-hole 86 with a finger. In this embodiment of the utility model, the purpose of this arrangement is that the limiting ring 84 and the mounting ring 83 are configured to be able to be limited up and down, and are installed inside the through port 82 and the limiting groove 81, thereby completing the positioning and installation of the dustproof net 85. This mainly seals or prevents dust from entering the corresponding positions of the mobile phone microphone, speaker and charging port, preventing dust from causing abnormalities in the functional modules.

[0024] Example 2: Please refer to Figures 1-5 This embodiment provides a technical solution based on embodiment one: the four corners of the inner wall of the mobile phone housing 1 are provided with rounded corners that are adapted to the outer edge of the corresponding mobile phone model; a positioning ring 2 is fixedly installed at the front of the inner wall of the mobile phone housing 1; the positioning ring 2 limits the position of the outer edge of the mobile phone screen placed inside the mobile phone housing 1 to prevent assembly from falling off; a heat dissipation hole 4 is provided on the back wall of the mobile phone housing 1 for heat dissipation of the mobile phone; an external protrusion 3 is provided at the top of the back wall of the mobile phone housing 1 for accommodating the mobile phone camera; a receiving groove 5 is provided on one side of the mobile phone housing 1 for accommodating the mobile phone power button; a receiving groove 7 is provided on the other side of the mobile phone housing 1 for accommodating the mobile phone volume button; and anti-slip protrusions 6 are evenly installed on the back wall of the mobile phone housing 1 to increase the friction with the hand and increase the grip stability. In this embodiment of the utility model, the purpose of this setting is that the positioning ring 2 mainly limits the position of the outer edge of the mobile phone screen, improves the stability of the connection between the mobile phone shell 1 and the mobile phone, and when the mobile phone is working for a long time, the setting of the heat dissipation hole 4 can improve the heat dissipation effect of the back of the mobile phone, and has the function of assisting heat dissipation.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] The phone case with the phone pad mechanism is made of thermoplastic polyurethane, which is both elastic and tough and can withstand a drop test of more than 1.5 meters. The transparent TPU shell is not easy to yellow, can show the original color of the phone, and is oil-resistant, water-resistant and mildew-resistant, making it a cost-effective choice. The external protrusion 3, receiving groove 1 5, and receiving groove 2 7 on the outside of the phone case 1 respectively accommodate the rear camera, power button and volume buttons. The heat dissipation holes 4 on the back wall of the phone case 1 can help dissipate the heat generated by the phone during operation, and prevent the phone from overheating due to heat accumulation inside the phone case 1. When assembling the dustproof component 8, the movable mounting ring 83 drives the dustproof net 85 and the limiting ring 84 to extend into the through-hole 82, and expands and deforms the through-hole 82, so that the bottom limiting ring 84 enters the inner wall of the lower limiting groove 81. The outer wall of the mounting ring 83 fits against the inner wall of the through-hole 82, while the upper limiting ring 84 fits against the inner wall of the upper limiting ring 84, thus completing the limiting placement of the dustproof net 85. The dustproof cover 87, which is hinged to the inner wall of the mounting groove 89, rotates and enters the inner wall of the through-hole 86 to seal the position of the mobile phone charging port. When using the phone case 1, the dustproof component 8 can seal or prevent dust from entering the corresponding positions of the phone microphone, speaker, and charging port. The dustproof mesh 85 does not seal the positions of the phone microphone and speaker and does not affect their use. It is just a mesh structure with a small aperture to prevent external dust from entering and causing abnormalities in the microphone and speaker functional modules. When you need to charge your phone charger, you can insert your finger into the inner wall of the insertion port 88, rotate the dust cover 87 in the mounting slot 89 to open it and detach it from the port 86, and then insert the charging head into the port 86 and into the phone charging port to complete the charging connection. After the dustproof mesh 85 filters out a certain amount of dust and impurities, the phone can be removed from the phone case 1 by pulling the corresponding opening 82 of the phone case 1. The movable mounting ring 83, limiting ring 84, and dustproof mesh 85 can then be removed from the opening 82, allowing for regular cleaning of the dustproof mesh 85. This protects the phone's microphone, speaker, and charging port from dust. At the same time, the positioning ring 2 limits the edge of the phone screen to prevent it from falling off the phone case 1. When using a phone with the phone case 1 attached, the anti-slip protrusions 6 increase friction with the hand, preventing the phone case 1 from slipping out of the hand and increasing grip stability.
