Technical Field
[0001] This application relates to the field of electronic product technology, and in particular to an electronic device. Background Technology
[0002] In related technologies, electronic devices, equipped with their own batteries, require charging to function properly; therefore, they are equipped with charging ports. To adapt to their intended use, electronic devices need to achieve a certain level of waterproofing. To prevent liquids from entering the electronic device through the charging port and damaging internal components, the waterproof sealing at the charging port needs to be strengthened. Utility Model Content
[0003] This application provides an electronic device that improves the waterproof performance of the charging port.
[0004] In a first aspect, embodiments of this application provide an electronic device, including:
[0005] The housing has a mounting cavity and a charging port communicating with the mounting cavity. The inner wall of the housing is provided with a protruding rib surrounding the charging port, and the protruding rib is spaced apart from the inner wall surface of the charging port.
[0006] A charging port is disposed within the mounting cavity, the charging port including a housing, the outer peripheral wall of the housing having a stepped surface; and
[0007] A waterproof sealing ring is fitted around the outer periphery of the housing. In the axial direction of the waterproof sealing ring, the waterproof sealing ring protrudes from the end face of the housing facing the charging port and is sandwiched between the stepped surface and the inner wall of the housing. In the radial direction of the waterproof sealing ring, the waterproof sealing ring is also sandwiched between the housing and the protruding rib.
[0008] In one embodiment, the inner edge of the waterproof sealing ring facing the charging port is provided with a sealing skirt, and the sealing skirt is sandwiched between the inner wall of the housing and the end face of the base facing the charging port.
[0009] In one embodiment, the waterproof sealing ring protrudes from the stepped surface in the radial direction, and the housing and the rib are spaced apart.
[0010] In one embodiment, the outer peripheral wall of the waterproof sealing ring and the two side walls of the waterproof sealing ring in the axial direction are connected by an arc-shaped transition.
[0011] In one embodiment, the ratio of the thickness of the portion of the waterproof sealing ring protruding from the end face of the housing facing the charging port in the axial direction to the overall thickness of the waterproof sealing ring is in the range of 0.1-0.2.
[0012] In one embodiment, the outer peripheral wall of the waterproof sealing ring is provided with waterproof ribs, and / or the inner peripheral wall of the waterproof sealing ring is provided with waterproof ribs.
[0013] In one embodiment, the electronic device further includes a waterproof cover, the waterproof cover comprising:
[0014] The fixing part connects to the housing;
[0015] A cover portion, adapted to the shape of the charging port, the cover portion being used to cover the charging port; and
[0016] A connecting part that connects the fixing part and the cover part.
[0017] In one embodiment, a sealing rib is provided on the outer peripheral wall of the cover portion. When the cover portion covers the charging port, the sealing rib elastically presses against the inner wall surface of the charging port.
[0018] In one embodiment, the outer edge of the end of the cover facing away from the charging port is provided with a cover skirt, and when the cover covers the charging port, the cover skirt abuts against the outer wall of the housing.
[0019] In one embodiment, the electronic device is a bone conduction headset or a headset charging case.
[0020] The electronic device based on the embodiments of this application achieves sealing stability through the elastic deformation of the waterproof sealing ring in its axial and radial directions. Specifically, in the axial direction, the waterproof sealing ring protrudes from the end face of the housing facing the charging port, causing the stepped surface of the outer peripheral wall of the housing and the inner wall of the housing to jointly apply compressive force to the waterproof sealing ring, resulting in axial elastic deformation. In the radial direction, the waterproof sealing ring fills the assembly gap between the rib and the outer peripheral wall of the housing, and simultaneously, under the compression of the inner peripheral wall of the rib and the outer peripheral wall of the housing, radial elastic deformation occurs. The inner wall of the housing, the inner peripheral wall of the rib, the stepped surface, and the outer peripheral wall of the housing form a limiting space, effectively limiting the risk of displacement of the waterproof sealing ring during installation or use. Through the elastic deformation of the waterproof sealing ring in the axial and radial directions, the waterproof sealing ring, together with the housing and the rib, forms a continuous sealing surface in the circumferential direction of the charging port, ultimately ensuring stable and effective waterproof performance of the electronic device at the charging port.

[0033] With the rapid iteration of technological advancements, electronic devices are exhibiting a diversified development trend. Devices such as wireless earphones, earphone cases, and mobile phones all require integrated rechargeable battery modules in their structural design, and charging ports are correspondingly incorporated to meet charging needs. To adapt to their usage scenarios, electronic devices need to achieve a certain level of waterproofing. To prevent liquids from entering the electronic device through the charging port and damaging internal components, a waterproof sealing ring is typically installed at the charging port. However, during the installation process, interference issues between the waterproof sealing ring and the casing can easily cause the sealing ring to shift, resulting in an incomplete continuous seal and affecting its proper waterproofing effect.
[0034] To resolve the above issues, please refer to [link / reference]. Figures 1 to 3 This application proposes an electronic device 10, which includes a housing 100, a charging port 200, and a waterproof sealing ring 300. The housing 100 has a mounting cavity 110 and a charging port 120 communicating with the mounting cavity 110. The inner wall of the housing 100 is provided with a protruding rib 130 surrounding the charging port 120, and the protruding rib 130 is spaced apart from the inner wall surface of the charging port 120. The charging port 200 is disposed in the mounting cavity 110 and includes a base shell 210. The outer peripheral wall of the base shell 210 is provided with a stepped surface 211. The waterproof sealing ring 300 is sleeved on the outer periphery of the base shell 210. In the axial direction, the waterproof sealing ring 300 protrudes from the end face of the base shell 210 facing the charging port 120 and is sandwiched between the stepped surface 211 and the inner wall of the housing 100. In the radial direction, the waterproof sealing ring 300 is also sandwiched between the base shell 210 and the protruding rib 130.
[0035] The sealing stability is achieved by the elastic deformation of the waterproof sealing ring 300 in its axial and radial directions. The specific principle is as follows: In the axial direction, the waterproof sealing ring 300 protrudes from the end face of the housing 210 facing the charging port 120, so that the stepped surface 211 of the outer peripheral wall of the housing 210 and the inner wall of the housing 100 jointly apply a compressive force to the waterproof sealing ring 300, causing it to produce elastic deformation in the axial direction; In the radial direction, the waterproof sealing ring 300 fills the assembly gap between the rib 130 and the outer peripheral wall of the housing 210, and at the same time, under the compression of the inner peripheral wall of the rib 130 and the outer peripheral wall of the housing 210, it produces elastic deformation in the radial direction. The inner wall of the housing 100, the inner peripheral wall of the rib 130, the stepped surface 211, and the outer peripheral wall of the base housing 210 form a limiting space, which effectively limits the risk of displacement of the waterproof sealing ring 300 during installation or use. Through the elastic deformation of the waterproof sealing ring 300 in the axial and radial directions, the waterproof sealing ring 300, together with the housing 100 and the rib 130, forms a continuous sealing surface in the circumferential direction of the charging port 120, ultimately ensuring the stable and effective waterproof performance of the electronic device 10 at the charging port 120.
[0036] Specifically, in one embodiment, the type of the charging port 200 includes, but is not limited to, Type-C, Micro USB, or Lightning.
[0037] Optionally, in one embodiment, the ratio of the thickness of the portion of the waterproof sealing ring 300 protruding from the end face of the housing 210 toward the charging port 120 in the axial direction of the waterproof sealing ring 300 to the overall thickness of the waterproof sealing ring 300 is in the range of 0.1-0.2.
[0038] It should be noted that the thickness of the portion of the waterproof sealing ring 300 protruding from the end face of the housing 210 facing the charging port 120 refers to the thickness of the portion of the waterproof sealing ring 300 protruding from the end face of the housing 210 facing the charging port 120 after installation. By controlling the thickness of the portion of the waterproof sealing ring 300 protruding from the end face of the housing 210 facing the charging port 120, excessive compression of the waterproof sealing ring 300 is avoided, thus preventing material fatigue caused by excessive compression. At the same time, insufficient compression of the waterproof sealing ring 300 is avoided, resulting in insufficient clamping force between the waterproof sealing ring 300 and the inner wall of the housing 100 and the stepped surface 211, thus preventing a decrease in the sealing effect between the waterproof sealing ring 300 and the inner wall of the housing 100 due to insufficient clamping force.
[0039] Understandably, the waterproof sealing ring 300 protrudes axially from the end face of the housing 210 facing the charging port 120. Under the compression of the stepped surface 211 and the inner wall of the housing 100, the waterproof sealing ring 300 undergoes axial elastic deformation, reducing its axial length. Considering that the waterproof sealing ring 300 still protrudes from the end face of the housing 210 facing the charging port 120 after installation, there is an assembly gap between the inner wall of the housing 100 and the end face of the housing 210 facing the charging port 120. This assembly gap is prone to accumulating dirt and may form a leakage path between the waterproof sealing ring 300 and the housing 210, affecting the waterproof performance at the charging port 120.
[0040] Therefore, in one embodiment, the inner edge of the waterproof sealing ring 300 facing the charging port 120 is provided with a sealing skirt, which is sandwiched between the inner wall of the housing 100 and the end face of the seat 210 facing the charging port 120.
[0041] By providing a sealing skirt on the inner edge of the waterproof sealing ring 300 facing the charging port 120, the sealing skirt can fill the assembly gap between the inner wall of the housing 100 and the end face of the seat 210 facing the charging port 120, eliminating possible leakage paths between the waterproof sealing ring 300 and the seat 210, and preventing dirt from accumulating between the inner wall of the housing 100 and the end face of the seat 210 facing the charging port 120.
[0042] Optionally, the side of the sealing skirt that is away from the waterproof sealing ring 300 is flush with the inner peripheral wall of the housing 210 to avoid the phenomenon that the sealing skirt is too long in the radial direction, which would affect the normal use of the charging port 200.
[0043] Specifically, the waterproof sealing ring 300 and the sealing skirt are integrated into a single structure, avoiding the seam interface caused by a separate structure and reducing potential leakage paths. At the same time, the integrated structural design makes the overall internal stress distribution more uniform and improves the elastic deformation capacity, allowing the waterproof sealing ring 300 to maintain a long-term sealing effect.
[0044] Please see Figure 3 In one embodiment, the waterproof sealing ring 300 protrudes from the stepped surface 211 in the radial direction, and the housing 210 and the ribs 130 are spaced apart.
[0045] When the waterproof sealing ring 300 is compressed, the housing 210 and the rib 130 are kept apart. On the one hand, this indicates that the assembly tolerance between the rib 130 and the housing 210 is large, which makes it easier to assemble the housing 210 with the waterproof sealing ring 300 on it with the inside of the rib 130. On the other hand, it can ensure that the waterproof sealing ring 300 generates sufficient elastic force under the compression of the rib 130 and the housing 210, so as to achieve a tight fit between the waterproof sealing ring 300 and the rib 130.
[0046] It should be noted that after the waterproof sealing ring 300 is installed, the housing 210 and the rib 130 can also abut against each other, meaning there is no assembly tolerance or the assembly tolerance between the rib 130 and the housing 210 is close to zero. While this increases the assembly difficulty of the waterproof sealing ring 300, it also improves the assembly stability between the housing 210 and the rib 130.
[0047] Please continue reading. Figure 3 In one embodiment, the outer peripheral wall of the waterproof sealing ring 300 and the two side walls of the waterproof sealing ring 300 in the axial direction are connected by an arc-shaped transition.
[0048] Understandably, the outer peripheral wall of the waterproof sealing ring 300 abuts against the inner peripheral wall of the rib 130, and the two axial side walls of the waterproof sealing ring 300 abut against the inner wall of the housing 100 and the stepped surface 211, respectively. After installation, the waterproof sealing ring 300 undergoes elastic deformation in both the axial and radial directions. While the outer peripheral wall of the waterproof sealing ring 300 is compressed and shortened, its two axial side walls are squeezed and lengthened. By setting an arc-shaped transition connection between the outer peripheral wall of the waterproof sealing ring 300 and its two axial side walls, a buffer gap is formed between the outer edges of the waterproof sealing ring 300 on both sides in the axial direction, the rib 130, and the housing 100. This buffer gap compensates for the axial and radial displacements generated when the waterproof sealing ring 300 is deformed under pressure. While accommodating the elastic deformation of the waterproof sealing ring 300, it also enhances the sealing effect between the waterproof sealing ring 300, the rib 130, and the housing 100.
[0049] In one embodiment, a waterproof rib is provided on the outer peripheral wall of the waterproof sealing ring 300. The waterproof rib is arranged in a ring shape. After the waterproof sealing ring 300 is installed, the waterproof rib abuts against the inner peripheral wall of the rib 130, which increases the friction between the waterproof sealing ring 300 and the rib 130 and enhances the sealing effect between the waterproof sealing ring 300 and the rib 130 under vibration conditions.
[0050] Specifically, the number of waterproof ribs can be set to multiple, and the multiple waterproof ribs are spaced apart in the axial direction of the waterproof sealing ring 300.
[0051] Similarly, waterproof ribs can also be provided on the inner peripheral wall of the waterproof sealing ring 300 to enhance the sealing connection between the waterproof sealing ring 300 and the housing 210. Accordingly, multiple waterproof ribs can be provided on the outer peripheral wall and inner peripheral wall of the waterproof sealing ring 300, respectively.
[0052] Specifically, in one embodiment, the waterproof sealing ring 300 is made of silicone or rubber. Both silicone and rubber possess high elastic deformation capacity, allowing them to quickly return to their original shape after being compressed, forming a stable sealing interface that effectively blocks liquid or gas penetration. Their flexibility allows the waterproof sealing ring 300 to compensate for assembly tolerances, and both silicone and rubber exhibit resistance to compression set, maintaining stable sealing force in long-term static sealing scenarios. Furthermore, silicone and rubber demonstrate basic tolerance to temperature fluctuations, ultraviolet radiation, and common environmental corrosive media, making them suitable for diverse applications such as outdoor equipment.
[0053] Please see Figures 2 to 4 In one embodiment, the electronic device 10 further includes a waterproof cover 400, which includes a fixing part 410, a covering part 420, and a connecting part 430; the fixing part 410 is connected to the housing 100; the covering part 420 is adapted to the shape of the charging port 120 and is used to cover the charging port 120; the connecting part 430 connects the fixing part 410 and the covering part 420.
[0054] By providing a waterproof cover 400 on the housing 100, the charging port 120 on the electronic device 10 can be covered by the cover portion 420 of the waterproof cover 400 when not in use. On the one hand, the cover portion 420 can provide a certain degree of waterproofing to the charging port 120, providing initial waterproofing before the waterproof sealing ring 300. On the other hand, it can prevent dirt from entering the charging port 200 through the charging port 120, thereby preventing dirt from affecting the normal use and service life of the charging port 200.
[0055] Furthermore, a sealing rib 421 is provided on the outer peripheral wall of the cover portion 420. When the cover portion 420 covers the charging port 120, the sealing rib 421 elastically presses against the inner wall surface of the charging port 120.
[0056] Understandably, when the cover 420 covers the charging port 120, the sealing rib 421 elastically presses against the inner wall surface of the charging port 120, which can strengthen the connection between the cover 420 and the inner wall surface of the charging port 120, preventing the cover 420 from releasing its closed state on the charging port 120 when the electronic device 10 is shaken. At the same time, it can also enhance the sealing effect of the cover 420 on the charging port 120, further enhancing the waterproof sealing effect at the charging port 120.
[0057] In one embodiment, a cover skirt 422 is provided on the outer edge of the end of the cover portion 420 facing away from the charging port 200. When the cover portion 420 covers the charging port 120, the cover skirt 422 abuts against the outer wall of the housing 100.
[0058] By providing a cover skirt 422 on the outer edge of the end of the cover portion 420 facing away from the charging port 200, when the cover portion 420 covers the charging port 120, the cover skirt 422 can shield the connection between the inner wall surface of the charging port 120 and the outer peripheral wall of the cover portion 420. Through the mating surface formed by the cover skirt 422 abutting against the outer wall of the housing 100, a sealing surface is formed on the outer periphery of the charging port 120, further enhancing the waterproof sealing effect at the charging port 120. Simultaneously, the cover skirt 422 protrudes from the outer wall of the housing 100, and the cover portion 420 can be released from its covering state on the charging port 120 by prying open the cover skirt 422.
[0059] Specifically, in one embodiment, the waterproof cover 400 is made of silicone or rubber. Both silicone and rubber possess high elastic deformation capacity, allowing them to quickly return to their original shape after being compressed, forming a stable sealing interface that effectively blocks liquid or gas penetration. Their flexibility allows the waterproof sealing ring 300 to compensate for assembly tolerances, and both silicone and rubber exhibit resistance to compression set, maintaining stable sealing force in long-term static sealing scenarios. Furthermore, silicone and rubber demonstrate basic tolerance to temperature fluctuations, ultraviolet radiation, and common environmental corrosive media, making them suitable for diverse applications such as outdoor equipment.
[0060] For example, electronic device 10 can be a bone conduction headphone. Bone conduction headphones transmit sound through bone conduction technology. Unlike traditional earbuds or in-ear headphones, their open design avoids pressure on the ear canal, but it also means that the device is more exposed to sweat, rain, or underwater environments, and therefore has higher requirements for waterproof performance. Since bone conduction headphones are one of the electronic devices 10 described above, they possess all the beneficial effects of the above embodiments, and will not be described in detail here.
[0061] It is understood that the electronic device 10 can also be a mobile phone, an earphone charging case, or an electronic watch. Any electronic device 10 with a charging port on its casing can adopt the solution proposed in this application to improve the waterproof sealing performance of the charging port.
