Description

Technical Field

[0001] This utility model relates to the field of product sealing technology, and in particular to a sealing structure and electronic equipment. Background Technology

[0002] Existing electronic products, especially those with external connectors (such as USB ports, headphone jacks, and charging ports), are often at risk of water or other contaminants entering the product. These connectors provide the product with the ability to connect to external devices, but they also provide a pathway for water and contaminants to enter the product's interior. Due to gaps at the connection between the connector and the casing, water and contaminants can enter the product through these gaps, causing damage to internal electronic components and affecting product performance and lifespan.

[0003] In related technologies, to prevent water and contaminants from entering the product through the gap at the connection between the connector and the outer shell, the connector is usually fixed to a mounting base, and a sealing ring gasket is fitted onto the connector, located between the outer wall of the mounting base and the inner wall of the outer shell. The sealing ring gasket is then bonded to the mounting base and the outer shell with adhesive, thereby preventing water and contaminants from entering the product through the gap at the connection between the connector and the outer shell, and improving the product's sealing and waterproof performance. However, using the above-mentioned adhesive bonding method to fix the sealing gasket makes the operation complicated when maintenance or replacement of the sealing gasket is required, and it is inconvenient to disassemble and replace it.

[0025] This utility model proposes a sealing structure 100.

[0026] Please see Figures 1 to 7 In one embodiment of this utility model, the sealing structure 100 includes a housing 1, a mounting base 2, a screw connector 4, and a first sealing ring gasket 5. The housing 1 has a mounting groove 11, and the bottom wall of the mounting groove 11 has an opening 13. The mounting base 2 is accommodated in the mounting groove 11, and the mounting base 2 has a connector 3, which is provided corresponding to the opening 13. The screw connector 4 passes through the bottom wall of the mounting groove 11 and the mounting base 2, and the mounting base 2 and the housing 1 are detachably connected. The first sealing ring gasket 5 is sleeved on the connector 3 and is located between the mounting base 2 and the housing 1.

[0027] In this utility model, by tightening the screw connector 4, the first sealing ring gasket 5 can be compressed, reducing the gap between it and the outer shell 1 and the mounting base 2, thereby enhancing the waterproof performance of the product. By reducing the gap between the first sealing ring gasket 5 and the outer shell 1 and the mounting base 2, the sealing performance and reliability of the product are also improved. Loosening the screw connector 4 to disassemble the mounting base 2, the outer shell 1, and the first sealing ring gasket 5 makes the maintenance and replacement process easier, simplifies the maintenance process, reduces labor costs and time, and also reduces the potential risk of damage due to improper maintenance. The screw connector 4 can be a screw or a bolt, and this utility model does not limit it.

[0028] To improve the sealing effect, please refer to Figures 3 to 7 In one embodiment of the present invention, the first sealing ring gasket 5 has a main body segment 51 and an elastic segment 52. The main body segment 51 is sleeved on the connector 3, and the elastic segment 52 is located on the side of the main body segment 51 facing away from the mounting base 2 and abuts against the bottom wall of the mounting groove 11. The main body section 51 is fitted onto the connector 3 and directly contacts the connector 3 on the mounting base 2, providing a preliminary seal. The elastic section 52 is located on the side of the main body section 51 facing away from the mounting base 2 and abuts against the bottom wall of the mounting groove 11. This design allows the elastic section 52 to provide additional compressive force when the screw 4 is tightened, enhancing the sealing effect. The presence of the elastic section 52 allows the first sealing ring gasket 5 to adapt to different installation gaps, ensuring good sealing performance under various conditions. When the screw 4 is tightened, the compression of the elastic section 52 can further reduce the gap between the first sealing ring gasket 5 and the housing 1 and the mounting base 2, thereby improving the sealing performance. The design of the elastic section 52 helps to improve the reliability of the sealing structure 100 and can compensate to some extent for gap changes caused by factors such as temperature changes, changes in air pressure inside and outside the housing 1, and mechanical vibration. Through the coordinated work of the main body section 51 and the elastic section 52, the risk of liquid or gas leakage through the sealing gap can be significantly reduced.

[0029] Please see Figures 3 to 7 The elastic segment 52 can be disposed in the middle or on both sides of the main body segment 51. The extension direction of the elastic segment 52 can be perpendicular to the main body segment 51 or at an angle (the angle is not limited). In some preferred embodiments of this utility model, the elastic segment 52 can be connected to the side of the main body segment 51 near the connector 3 and inclined at 60 degrees close to or away from the connector 3. The elastic segment 52 can also be connected to the side of the main body segment 51 away from the connector 3 and inclined at 60 degrees close to or away from the connector 3. The height of the elastic segment 52 can be set between 0.2 mm and 1 mm. This utility model does not limit this.

[0030] Further, please refer to Figure 3In one embodiment of this utility model, the cross-sectional area of ​​the elastic segment 52 gradually decreases from the end near the main body segment 51 to the end away from the main body segment 51. This gradual decrease in cross-sectional area helps the elastic segment 52 to compress more evenly when the screw 4 is tightened, resulting in a more consistent sealing pressure across the entire contact surface. The gradually decreasing cross-sectional area also helps achieve a more uniform stress distribution on the elastic segment 52, reducing local stress concentration. This can extend the service life of the first sealing ring gasket 5 and reduce the risk of damage due to stress concentration. Because the cross-sectional area of ​​the elastic segment 52 gradually decreases, the compression of the elastic segment 52 when the screw 4 is tightened can more effectively fill the gap between the mounting base 2 and the outer shell 1, improving the sealing effect. The gradually decreasing cross-sectional area design allows the elastic segment 52 to better adapt to different gap sizes between the mounting base 2 and the outer shell 1, ensuring good sealing performance under various installation conditions.

[0031] Specifically, please refer to Figure 3 In one embodiment of this utility model, the mounting base 2 has an annular groove 21, and the first sealing ring gasket 5 is confined within the annular groove 21 and partially exposed at the opening of the annular groove 21. The first sealing ring gasket 5 is arranged around the connector 3. The mounting base 2 has an annular groove 21 to accommodate the first sealing ring gasket 5 and ensure its correct positioning. The first sealing ring gasket 5 being confined within the annular groove 21 means that the first sealing ring gasket 5 is fixed in the annular groove 21 and will not move within the mounting base 2. The partial exposure of the first sealing ring gasket 5 at the opening of the annular groove 21 allows the first sealing ring gasket 5 to directly contact the bottom wall of the mounting groove 11 and fill the gap between the mounting base 2 and the outer shell 1, improving the sealing effect. The first sealing ring gasket 5 is arranged around the connector 3, meaning that the first sealing ring gasket 5 forms a closed ring around the connector 3, ensuring that the entire area around the connector 3 is sealed, which helps to provide a more comprehensive seal and reduce the risk of leakage.

[0032] Please see Figure 1 In one embodiment of this utility model, the mounting base 2 has a connecting post 22, and the first sealing ring gasket 5 is arranged around the connecting post 22. The screw connector 4 passes through the bottom wall of the mounting groove 11 and is screwed to the connecting post 22. The mounting base 2 has a connecting post 22 to cooperate with the screw connector 4 to fix the mounting base 2 and the outer shell 1. The first sealing ring gasket 5 is arranged around the connecting post 22. When the screw connector 4 is tightened, the screw connector 4 will apply pressure to the connecting post 22. This pressure will be transmitted to the first sealing ring gasket 5, making it fit more tightly against the mounting base 2 and the outer shell 1, thereby achieving a better seal, improving the sealing performance between the first sealing ring gasket 5 and the mounting base 2 and the outer shell 1, and reducing the risk of leakage.

[0033] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the sealing structure 100 includes a cover 6 and a second sealing ring gasket 7. The cover 6 is disposed on the outer shell 1, and a protrusion 61 is formed on one side of the cover 6. The second sealing ring gasket 7 is sleeved on the protrusion 61 and is located between the inner peripheral wall of the mounting groove 11 and the outer peripheral wall of the protrusion 61. The cover 6 is disposed on the outer shell 1 to seal and protect the internal components. The protrusion 61 is formed on one side of the cover 6 to cooperate with the outer shell 1 to achieve a seal between the cover 6 and the outer shell 1. The second sealing ring gasket 7 is sleeved on the protrusion 61 and is located between the inner peripheral wall of the mounting groove 11 and the outer peripheral wall of the protrusion 61. It can provide an additional sealing effect at the connection between the cover 6 and the outer shell 1, fill and compensate for the small gaps between the cover 6 and the outer shell 1, and prevent the leakage of fluid, gas or dust. In one embodiment, the protruding post 61 is also provided with a limiting groove, and the second sealing ring gasket 7 is limited within the limiting groove. The design of the limiting groove helps to fix the position of the second sealing ring gasket 7, improves the positioning accuracy of the second sealing ring gasket 7, and reduces the risk of sealing failure due to improper installation.

[0034] To enhance the sealing performance of the connection between the cover 6 and the outer shell 1, please refer to [link / reference]. Figure 1 and Figure 2 In one embodiment of this utility model, the cross-sectional area of ​​the second sealing ring gasket 7 gradually decreases from the end near the protrusion 61 to the end away from the protrusion 61. This gradual decrease in cross-sectional area helps the second sealing ring gasket 7 to fit more tightly against the protrusion 61 and the inner circumferential wall of the mounting groove 11 when the cover 6 is connected to the outer shell 1, thereby improving the sealing effect. Due to the gradual decrease in cross-sectional area, the second sealing ring gasket 7 can better adapt to different pressure distributions when subjected to pressure, ensuring uniform sealing pressure across the entire contact surface. The gradually decreasing cross-sectional area design also reduces the risk of leakage of fluid, gas, or dust through the tiny gap between the cover 6 and the outer shell 1, and to some extent compensates for gap changes caused by temperature variations, mechanical vibrations, etc., thus contributing to improved reliability of the sealing structure 100.

[0035] To balance the internal and external air pressure of the outer casing 1, please refer to 2. In one embodiment of this utility model, the outer casing 1 is provided with vent holes 12, and the sealing structure 100 includes a waterproof and breathable membrane 8. The waterproof and breathable membrane 8 is connected to the outer casing 1 and covers the vent holes 12. The vent holes 12 on the outer casing 1 allow gas to pass through, thereby balancing the air pressure inside and outside the outer casing 1 and preventing deformation or damage to the outer casing 1 due to pressure differences. The waterproof and breathable membrane 8 is connected to the outer casing 1 and covers the vent holes 12. This membrane allows air molecules to pass through but prevents water molecules and solid particles, thereby achieving the effect of being breathable but not waterproof. The waterproof and breathable membrane 8 can effectively balance the air pressure between the inside of the outer casing 1 and the external environment, which is very important for preventing equipment failure due to air pressure changes. The microporous structure of the waterproof and breathable membrane 8 prevents water molecules from passing through, thereby protecting the internal components from moisture damage. In addition to being waterproof, the breathable membrane can also prevent dust and other solid particles from entering the interior of the outer casing 1, keeping the internal components clean. The waterproof and breathable membrane 8 allows gas to pass freely, which helps with heat dissipation and prevents condensation, which is especially important for electronic devices. In one embodiment, a limiting step is formed around the vent 12, and the waterproof and breathable membrane 8 is connected to a step surface of the limiting step. The setting of the limiting step can provide precise positioning for the waterproof and breathable membrane 8 and prevent the waterproof and breathable membrane 8 from being touched and falling off to a certain extent, thereby enhancing the installation reliability of the waterproof and breathable membrane 8.

[0036] Please refer to 1. In one embodiment of this utility model, the sealing structure 100 further includes a circuit board 9. The mounting base 2 has a positioning groove 23. The connector 3 passes through one side wall of the positioning groove 23. The circuit board 9 is confined within the positioning groove 23 and electrically connected to the connector 3. The positioning groove 23 of the mounting base 2 provides stable support and precise positioning for the circuit board 9, ensuring proper fit between the circuit board 9 and other components. The connector 3 passing through one side wall of the positioning groove 23 allows for electrical connection between the connector 3 and the circuit board 9 while maintaining structural stability and sealing. The electrical connection between the circuit board 9 and the connector 3 ensures that the circuit board 9 can receive and transmit electrical signals, meeting the functional requirements of the electronic device.

[0037] This utility model also proposes an electronic device, which includes the aforementioned sealing structure 100. The specific structure of the sealing structure 100 is as described in the above embodiments. Since this electronic device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
