Description

Technical Field

[0001] This utility model relates to the field of electrical equipment products technology, and in particular to an electronic product. Background Technology

[0002] In the design and manufacturing of electronic products, screws are widely used as a basic fastener to secure housings, circuit boards, batteries, and other internal components (such as heat dissipation modules and connectors). Their advantages lie in their simple structure, low cost, and ease of standardized production.

[0003] However, electronic products (such as mobile phones and small speakers) require frequent disassembly of screws during repair or upgrade. Due to the small internal space and tiny screw size (commonly less than 3mm in diameter), screws are easily slipped from the casing or the hands of repair personnel during disassembly and fall into the gaps of the equipment or onto the ground, making them difficult to retrieve.

[0023] Currently, electronic products (such as mobile phones and small speakers) require frequent disassembly of screws during repair or upgrade. Due to the small internal space and tiny screw size (commonly less than 3mm in diameter), screws are easily slipped from the casing or the hands of repair personnel during disassembly and fall into the gaps of the equipment or onto the ground, making them difficult to retrieve.

[0024] This utility model proposes an electronic product.

[0025] Please see Figure 1 , Figure 3 and Figure 6 In one embodiment of this utility model, the electronic product 100 includes:

[0026] The upper cover 1 includes a cover body 11 and an extension plate 12 protruding from the cover body 11.

[0027] The bottom shell 2 has an open cavity. The cover body 11 is detachably installed at the opening, and the extension plate 12 extends into the cavity. A through hole 21 is provided on the side wall of the bottom shell 2. The through hole 21 includes a threaded hole 211 and a non-threaded hole 212 connected to each other. The threaded hole 211 is located close to the cavity, and its diameter is larger than that of the non-threaded hole 212.

[0028] The connector 3 includes a threaded section 31 and a non-threaded section 32 connected to each other. The threaded section 31 is threadedly connected to the threaded hole 211, and the non-threaded section 32 is movably inserted into the non-threaded hole 212 and the threaded hole 211.

[0029] The technical solution of this utility model involves detachably mounting the cover body 11 at the opening on the bottom shell 2, allowing the extension plate 12 to be inserted into the cavity. The through hole 21 on the bottom shell 2 includes two connected parts: a threaded hole 211 and a non-threaded hole 212. The connector 3 includes two connected parts: a threaded section 31 and a non-threaded section 32. During installation, the connector 3 is first inserted into the through hole 21 from inside the bottom shell 2. Then, from outside the bottom shell 2, the connector 3 is rotated clockwise using a driving component, causing the threaded section 31 to screw into the threaded hole 211 and abut against the extension plate 12 on the top cover 1, while the non-threaded section 32 remains in the non-threaded hole 212. During disassembly, the connector 3 is rotated counterclockwise from outside the bottom shell 2 using a driving component, causing the connector 3 to move outward from the bottom shell 2, thereby disengaging from the extension plate 12. Please refer to... Figure 2 Since the diameter of the threaded hole 211 is larger than that of the non-threaded hole 212, that is, the outer diameter of the threaded section 31 is larger than that of the non-threaded section 32, when the connector 3 is disassembled, the threaded section 31 cannot pass through the non-threaded hole 212 and fall out of the bottom shell 2. Instead, it is kept in the cavity of the bottom shell 2, preventing the connector 3 from being lost and significantly reducing the time the user spends searching for the connector 3 during disassembly.

[0030] Specifically, the electronic product 100 includes, but is not limited to, speakers, display devices, etc., which are not limited here. To enhance the connection strength of the upper cover 1, an extension plate 12 protruding from the cover body 11 extends into the bottom shell 2, and the upper cover 1 and the bottom shell 2 are fixed by the abutment of the connector 3 and the extension plate 12. In one embodiment, a flange or protrusion may be formed on the periphery of the side of the upper cover 1 facing the bottom shell 2. Correspondingly, a support structure adapted to the flange or protrusion is provided on the bottom shell 2 to realize the cooperation between the upper cover 1 and the bottom shell 2. In this embodiment, the shape of the bottom shell 2 and the upper cover 1 is not specifically limited. For example, the upper cover 1 can be a square plate, and the bottom shell 2 can be a square box adapted to it, as long as it is a hollow structure with a cavity. In addition, the driving component for driving the connector 3 to rotate can be a screwdriver, a wrench, or a hex wrench, etc.

[0031] In the embodiments of this utility model, please refer to Figure 4 The connector 3 has a first drive groove 321, which is located at the end of the non-threaded section 32 away from the threaded section 31. The shape of the first drive groove 321 includes, but is not limited to, slotted, hexagonal, Phillips, or Torx shapes. The drive component is a screwdriver or wrench that matches the shape of the first drive groove 321. In this way, the drive component can rotate the first drive groove 321 counterclockwise or clockwise from the outside of the bottom shell 2.

[0032] In the embodiments of this utility model, please refer to Figure 5The connector 3 has a second driving groove 311, located at the end of the threaded section 31 furthest from the non-threaded section 32. The shape of the second driving groove 311 can be the same as that of the first driving groove 321, such as a straight line, hexagon, cross, or star shape. The first driving groove 321 and the second driving groove 311 can be machined by turning, injection molding, milling, etc., and the machining method is not limited here. It is understood that the (structural) dimensions of the second driving groove 311 and the first driving groove 321 are not limited; that is, the dimensions of the first driving groove 321 and the second driving groove 311 can be kept consistent, so that only one tool is needed to unlock the first driving groove 321 and the second driving groove 311. The dimensions of the first driving groove 321 and the second driving groove 311 can also be kept inconsistent to adapt to different mechanical requirements and optimize the overall structural strength.

[0033] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The bottom shell 2 is provided with a gas channel 22. The inlet of the gas channel 22 is connected to a non-threaded hole 212. An air passage gap is formed between the outer wall of the non-threaded section 32 and the hole wall of the non-threaded hole 212. The outlet of the gas channel 22 is connected to the cavity, and a waterproof and breathable membrane 23 is provided at the outlet of the gas channel 22. The gas channel 22 is designed to balance the air pressure inside the cavity: when the air inside the cavity is heated and expands, the internal air pressure increases, and the pressure inside the cavity is higher than the external ambient pressure. The internal air will attempt to flow outward, passing through the gas channel 22 and the air passage gap to flow outward to the outside of the bottom shell 2 until the internal and external air pressures are basically balanced. Similarly, when the air inside the cavity cools and contracts, the internal air pressure decreases, and the external ambient pressure is higher than the internal cavity pressure. Under the action of the external pressure difference, the air in the external environment will attempt to flow inward. The air first enters through the air passage gap, and then flows along the gas channel 22 through the waterproof and breathable membrane 23 into the internal cavity until the internal and external air pressures are balanced again. This ensures that the air pressure inside the cavity is always consistent with the external air pressure.

[0034] It should be noted that the waterproof and breathable membrane 23 can be made of thin film materials such as polytetrafluoroethylene (PTFE) expanded membrane, microporous polyolefin membrane, or waterproof fabric with excellent breathability. It can not only prevent moisture from entering the cavity, but also effectively balance the air pressure, thereby achieving the effect of "breathable but not water-permeable".

[0035] In the embodiments of this utility model, please refer to Figure 3 and Figure 4The electronic product 100 also includes a first sealing element 4, which is sleeved on the outer periphery of the non-threaded section 32 and has an interference fit with the wall of the non-threaded hole 212. The first sealing element 4 is located between the inlet of the gas passage 22 and the threaded section 31. The first sealing element 4 can be a ring-shaped part made of materials such as silicone, fluororubber, or nitrile rubber, such as a standard O-ring or lip ring, as long as it can be embedded in the non-threaded hole 212 to seal the gas passage gap.

[0036] In the embodiments of this utility model, the first sealing element 4 is made of a flexible material, such as silicone or rubber, which has excellent elasticity and resilience. When it is pressed into the limiting groove 322 and cooperates with it, it can better fill the small irregularities or tolerance fluctuations that may exist between the outer wall of the non-threaded section 32 and the hole wall, thereby improving the sealing effect of the first sealing element 4 on the gap of the non-threaded hole 212.

[0037] In the embodiments of this utility model, please refer to Figure 5 A limiting groove 322 is provided on the outer periphery of the non-threaded section 32, and the first sealing element 4 is partially disposed within the limiting groove 322. The limiting groove 322 can be an annular groove provided on the outer peripheral surface of the non-threaded section 32. The width of the annular groove is approximately equal to the thickness of the first sealing element 4, and the depth is slightly less than the cross-sectional height of the first sealing element 4, so that the first sealing element 4 is interference-fitted between the annular groove and the non-threaded hole 212. The setting of the limiting groove 322 provides a clear installation position and physical constraint for the first sealing element 4, making it less likely for the first sealing element 4 to shift, twist, or fall off during assembly.

[0038] In the embodiments of this utility model, please refer to Figure 6 and Figure 7 The electronic product 100 also includes a snap-fit ​​structure 5, which connects the cover body 11 and the bottom shell 2. The type of snap-fit ​​structure 5 is not specifically limited; it can be a spring-loaded snap-fit ​​51, for example, with one or more outwardly or inwardly bent elastic metal or plastic pieces (hooks) on the edge or at a specific location on the cover body 11, and a recessed slot 52 or a raised pin on the corresponding location on the bottom shell 2 (such as the middle frame); it can also be a rotary snap-fit ​​51, with one or more relatively rotatable snap-fit ​​components at the connection between the cover body 11 and the bottom shell 2. For example, the cover body 11 has a grooved cylinder, and the bottom shell 2 has a rotary seat with an elastic arm and teeth; it can also be a butt-fit snap-fit ​​51, for example, with protrusions and recesses on the edges of the cover body 11 and the bottom shell 2, or both having protrusions and recesses but complementary shapes. Furthermore, the mating surfaces of both can have a certain taper or slope to accommodate installation at different angles.

[0039] In the embodiments of this utility model, please refer to Figure 6 and Figure 7 The snap-fit ​​structure 5 includes a snap-fit ​​51 and a slot 52 that engages with the snap-fit ​​51. The snap-fit ​​51 is located on the cover body 11, and the slot 52 is located on the inner wall of the bottom shell 2. The cover body 11 corresponds to the opening and seals the cavity. The snap-fit ​​51 and the extension plate 12 are both located on the same side of the cover body and extend towards the interior of the cavity. The cover body 11 is connected to the bottom shell 2 by snapping the snap-fit ​​51 with the slot 52. For the connection between the snap-fit ​​51 and the slot 52, the cover body 11 can be moved manually in a preset direction to push the snap-fit ​​51 into the slot 52; alternatively, the extension plate 12 can be pressed by the movement of the connector 3 into the cavity, thereby pushing the snap-fit ​​51 on the cover body 11 closer to the slot 52, thus preventing the snap-fit ​​51 from falling out of the slot 52. The buckle 51 and the slot 52 are configured as a one-to-one snap-fit ​​structure 5. Multiple snap-fit ​​structures 5 are set at intervals. In this way, by setting multiple snap-fit ​​structures 5, the cover body 11 and the bottom shell 2 are snapped together at different positions, which helps to strengthen the connection between the cover body 11 and the bottom shell 2.

[0040] In the embodiments of this utility model, please refer to Figure 1 The electronic product 100 also includes a second sealing element 6, which extends along the periphery of the cover body 11. The second sealing element 6 can be a sealing gasket or sealing ring, and can be made of rubber materials such as silicone rubber, nitrile rubber, or fluororubber, or polyurethane elastomer. Its shape can be circular, cuboid, or other shapes that match the periphery of the opening. The second sealing element 6 can be fixed to the cover body 11 by bonding, snap-fitting 51, or embedding. Bonding involves applying adhesive to the contact surfaces of the second sealing element 6 and the cover body 11 to bond them together. Snap-fitting utilizes the slots 52 or snap-fit ​​structures on the cover body 11 to fix the second sealing element 6. Embedding involves pre-embedding the second sealing element 6 into the groove of the cover body 11. By providing the second sealing element 6, the gap between the upper cover 1 and the bottom shell 2 is sealed, thereby improving the sealing performance of the cavity space.

[0041] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
