[0031] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
[0032] This application discloses an electronic device, including but not limited to walkie-talkies, mobile phones, tablets, or laptops.
[0033] like Figures 1 to 3 As shown, in some embodiments, the electronic device includes a sealing structure that includes a housing 10 and a seal 20.
[0034] The following section will first introduce some of the structures of the casing 10, such as... Figure 4 and Figure 5 As shown, the housing 10 is provided with a receiving part 11 and an interface groove 12. The receiving part 11 and the interface groove 12 may be provided on the side or bottom of the housing 10.
[0035] The receiving portion 11 has a first end and a second end in the axial direction. The cross-sectional dimension of the inner cavity of the receiving portion 11 gradually decreases from the first end to the second end. Preferably, the inner cavity of the receiving portion 11 can be approximately frustum-shaped, and its inner wall surface can form a guide surface. The inner cavity of the receiving portion 11 is provided with a protrusion 111, which is located near the second end. The protrusion 111 can be one or more, for example, one or two. When two are provided, the two protrusions 111 can be arranged opposite each other, so that there is a certain gap between them.
[0036] Furthermore, the receiving portion 11 is provided with at least two through slots 112, which penetrate the inner and outer walls of the receiving portion 11, such that the portion of the receiving portion 11 located between the at least two through slots 112 forms a latching portion 11a, and the portion of the receiving portion 11 excluding the latching portion 11a can form a limiting structure 11b (e.g., Figure 4 As shown, the elasticity of the limiting structure 11b is less than that of the snap-fit portion 11b. Understandably, the receiving portion 11 itself has a certain elasticity. When the receiving portion 11 and the connecting portion 22 cooperate, there is a certain fit margin. The structure of the receiving portion 11 can reduce the end deformation of the seal 20 during assembly. The assembly of the seal 20 is achieved by the deformation of the snap-fit portion 11a itself, and the seal 20 can still maintain a large engagement amount, providing sufficient pull-out force.
[0037] Of course, in other embodiments, the receiving portion 11 may be formed by a plurality of snap-fit portions 11a.
[0038] In some embodiments, the interface slot 12 may be, but is not limited to, a type-A interface slot, a type-C interface slot, or a headphone jack slot.
[0039] The structure of seal 20 is described below, such as Figures 6 to 9 As shown, the seal 20 includes a body 21, which is generally elongated. The body 21 has a first surface and a second surface. The first surface of the body 21 is provided with a connecting portion 22 and a sealing portion 23. The connecting portion 22 and the sealing portion 23 are spaced apart along a first direction of the body 21, which may be the length direction of the body 21. The connecting portion 22 is used for assembly within the receiving portion 11, and the sealing portion 23 is used for sealing the interface groove 12.
[0040] The connecting part 22 is generally columnar, and the cross-sectional size of the connecting part 22 gradually decreases from the side closer to the main body 21 to the side farther away from the main body 21. For example, the connecting part 22 can be generally frustum-shaped, so that the connecting part 22 can be guided and matched with the inner cavity of the receiving part 11.
[0041] The end of the connecting portion 22 away from the main body 21 is provided with a limiting protrusion 221, and the outer surface of the limiting protrusion 221 is provided with at least one notch 2212. Specifically, the outer surface of the end of the connecting portion 22 away from the main body 21 can extend outward with a limiting protrusion 221, and the cross-sectional size of the limiting protrusion 221 gradually decreases from the side closer to the main body 21 to the side farther away from the main body 21, so that the limiting protrusion 221 can guide and cooperate with the inner cavity of the receiving portion 11.
[0042] The limiting protrusion 221 forms a limiting surface 2211 on the side facing the main body 21, or in other words, the limiting surface 2211 can be formed on the upper surface of the limiting protrusion 221. The outer surface of the limiting protrusion 221 also has at least one notch 2212, which penetrates both axial sides of the limiting protrusion 221 (e.g., ...). Figure 6 and Figure 7 As shown, the notch 2212 is provided to facilitate the installation of the limiting protrusion 221 into the receiving part 11. During this process, the limiting protrusion 221 can deform towards the notch 2212, reducing the resistance to the installation of the limiting protrusion 221.
[0043] Furthermore, one or more notches 2212 can be provided, for example, one, two, or three. When two notches 2212 are provided, they can be positioned opposite each other, with a certain distance between them. This allows the connecting part 22 to be installed into the receiving part 11. During the installation of the limiting protrusion 221 into the receiving part 11, the limiting protrusion 221 can deform towards the notch 2212, reducing the resistance to the installation of the limiting protrusion 221. When the connecting part 22 moves along the inner cavity of the receiving part 11, the protrusion 111 is positioned opposite the notch 2212, allowing the connecting part 22 to move smoothly along the inner cavity of the receiving part 11, thereby enabling the connecting part 22 to be assembled into or disengaged from the receiving part 11. When the connecting part 22 is fixed relative to the receiving part 11, the end of the second end of the receiving part 11 abuts against the surface of the limiting surface 2211 facing the main body 21 (or the limiting surface 2211), and the protrusion 111 and the notch 2212 are offset, so that the connecting part 22 is not easy to come out of the receiving part 11.
[0044] Understandably, the seal 20 can seal and protect the relevant interfaces / ports on the housing 10. Furthermore, the seal 20 is easier to assemble into the housing 10, effectively improving assembly efficiency and reducing unnecessary materials and assembly processes. In addition, the connecting part 22 of the seal 20 is not easily dislodged from the receiving part 11 of the housing 10, which can improve connection stability.
[0045] In some embodiments, the latching portion 11a and the protrusion 111 of the receiving portion 11 are not limited to the positions described above. Under different requirements, the structure can be adjusted accordingly based on the different opening angles and rotation directions of the connecting portion 22 of the seal 20, ultimately achieving the purpose of reliable and easy assembly. The latching portion 11a of the receiving portion 11 should not be too wide, and the larger the relative rotation angle between the protrusion 111 and the notch 2212, the better, so as to reduce the possibility of the connecting portion 22 disengaging from the receiving portion 11 of the housing 10.
[0046] like Figure 9 As shown, in some embodiments, the outer periphery of the portion of the connecting part 22 located between the main body 21 and the limiting protrusion 221 is provided with at least one first sealing protrusion 222. The first sealing protrusion 222 is annular and can improve the sealing performance. There may be one or more first sealing protrusions 222. When there are multiple first sealing protrusions 222, they may be spaced apart along the axial direction of the connecting part 22.
[0047] When the connecting part 22 is fixed inside the receiving part 11, the circumferential outer side of the first sealing protrusion 222 abuts against the inner wall surface of the receiving part 11 to achieve a seal.
[0048] Of course, at least one sealing ring may be provided on the outer periphery of the connecting part 22.
[0049] In some embodiments, the connecting part 22 is a hollow structure or a solid structure. Preferably, the connecting part 22 is a hollow structure with its opening at the end of the connecting part 22 away from the main body 21. The hollow structure allows the connecting part 22 to have a certain degree of elasticity, which can increase its deformation and allow it to be better assembled into the receiving part 11.
[0050] like Figures 6 to 9 As shown, in some embodiments, the sealing part 23 is columnar, such as cylindrical. Further, the outer circumferential side of the sealing part 23 is provided with a mounting groove 231, and a sealing ring 24 is provided in the mounting groove 231. The sealing ring 24 can be a silicone sealing ring. When the sealing part 23 is installed in the interface groove 12, the outer circumferential surface of the sealing ring 24 abuts against the inner wall surface of the interface groove 12, thereby improving the sealing performance.
[0051] In other embodiments, the outer circumferential side of the sealing part 23 is provided with at least one second sealing protrusion. The second sealing protrusion is annular. When the sealing part 23 is installed in the interface groove 12, the outer circumferential surface of the second sealing protrusion abuts against the inner wall surface of the interface groove 12, thereby improving the sealing performance.
[0052] Of course, the sealing part 23 can also be interference-fitted with the interface groove 12 to achieve a seal.
[0053] In some embodiments, the sealing portion 23 may be a hollow structure or a solid structure.
[0054] like Figures 6 to 9 As shown, in some embodiments, the first surface of the main body 21 is provided with a first recess 211, which extends along the second direction of the main body 21, and / or the second surface of the main body 21 is provided with a second recess 212, which extends along the second direction of the main body 21. The second recess 212 may be disposed opposite to the first recess 211. Here, the second direction may be the width direction of the main body 21. Understandably, the first recess 211 and / or the second recess 212 are provided such that the thickness of a portion of the first recess 211 and / or the second recess 212 is smaller than the thickness of other portions of the main body 21, so that the main body 21 can deform in the vertical direction, making it convenient for the user to pull up or press the connecting portion 22 and / or the sealing portion 23.
[0055] In some embodiments, the main body 21 has an operating part 25 at one end near the sealing part 23, and the operating part 25 is disposed on the side near the sealing part 23. Preferably, the operating part 25 can be a concave-convex structure. Understandably, providing the operating part 25 facilitates the user to remove the sealing part 23.
[0056] In some embodiments, the seal 20 may be a silicone component, and the seal 20 may be made of silicone or rubber material. Of course, the seal 20 may also be made of other soft and elastic materials, and no specific limitation is made here.
[0057] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
