Description

Technical Field

[0001] This utility model relates to the field of shell protection technology, and in particular to a waterproof button pad and shell. Background Technology

[0002] With the widespread adoption of electronic devices (such as wearable devices and alarms), their application scenarios have expanded from traditional indoor environments to complex scenarios such as outdoor sports, underwater operations, and high-humidity industrial environments. However, existing electronic devices still have significant shortcomings in terms of waterproof performance:

[0003] Firstly, liquid can easily seep into parts of the device's casing, such as button holes, indicator light holes, and speaker / microphone openings, due to poor sealing.

[0004] Secondly, traditional waterproofing technologies (such as waterproof adhesive layers and sealing rings) are prone to failure after long-term use due to material aging, mechanical wear, or temperature changes. When installed on electronic devices, they require additional materials for installation, making installation, disassembly, and use inconvenient.

[0005] In addition, existing solutions require damaging the sealing structure during repairs, leading to increased maintenance costs. Utility Model Content

[0006] This utility model provides a waterproof button sleeve and housing, which solves the problems of water leakage due to poor sealing, cumbersome installation and disassembly, unnecessary material consumption, and high maintenance costs in the waterproof technology used in the housing of electronic devices in the prior art.

[0007] To solve the above-mentioned technical problems, the present invention provides a waterproof button sleeve, including a base pad, at least one set of sealing rings and button caps are provided on the outer surface of the base pad, the upper surface of the button caps is higher than the upper surface of the sealing rings, the sealing rings are arranged around the button caps, a gap is left between the outer periphery of the button caps and the inner periphery of the sealing rings, and a button cavity corresponding to the button caps is provided on the inner surface of the base pad.

[0008] In some embodiments, the waterproof button sleeve is integrally molded and is made of a flexible, waterproof material.

[0009] This utility model also provides a housing on which a waterproof button sleeve as described above is installed.

[0010] In some embodiments, at least one opening is provided on the housing to accommodate the button cap. A set of annular inner walls and annular outer walls are provided inside the housing corresponding to the opening. The annular outer walls surround the annular inner walls. An annular groove is provided between the annular inner walls and the annular outer walls, so that the sealing ring is embedded in the annular groove.

[0011] In some embodiments, the inner diameter of the opening is larger than the outer diameter of the button cap, so that the button cap can be pressed outside the housing.

[0012] In some embodiments, the width of the annular groove is equal to or less than the width of the sealing ring, and the depth of the annular groove is greater than the height of the sealing ring.

[0013] In some embodiments, at least two openings are provided on the housing, and each opening corresponds to a set of annular inner walls and annular outer walls inside the housing.

[0014] In some embodiments, the housing further includes a circuit board with at least one protruding button. The button's position on the circuit board corresponds to the button cavity of the waterproof button sleeve. When the circuit board is fixedly installed in the housing, the button is housed within the button cavity.

[0015] In some embodiments, the bottom of the waterproof button sleeve contacts the circuit board, and when the circuit board is fixed to the housing, the circuit board will keep the sealing ring embedded in the annular groove.

[0016] The beneficial effects of this utility model are as follows: The waterproof button sleeve of this application is made of waterproof material and is integrally molded. When used in conjunction with the housing, the lateral elastic deformation (in the thickness direction of the sealing ring) of the waterproof button sleeve achieves a seal on the side of the annular groove of the sealing ring and the housing, which not only effectively prevents water from entering the housing, but also ensures a seal even if the housing ages or deforms under stress during use; it also does not require bonding to the housing during installation, making installation and disassembly simple, convenient and quick.

[0025] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0026] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0027] like Figures 1 to 3 As shown, the waterproof button sleeve 1 of this utility model includes a base pad 11. At least one set of sealing rings 12 and button caps 13 are provided on the outer surface of the base pad 11. The upper surface of the button cap 13 is higher than the upper surface of the sealing rings 12. The sealing rings 12 are arranged around the button caps 13. A gap 14 is left between the outer periphery of the button caps 13 and the inner periphery of the sealing rings 12. A button cavity 15 corresponding to the button caps 13 is provided on the inner surface of the base pad 11.

[0028] The waterproof button sleeve 1 of this utility model, when used in conjunction with the housing, accommodates the buttons inside the housing through the button cavity 15, and is tightly accommodated in the space between the annular inner wall and the annular outer wall of the housing through the sealing ring 12. It can effectively prevent water from entering the housing and protect the internal components. When in use, it can be sealed and fixed to the housing without the need for adhesive or screw fastening. Instead, it is installed by compression, which makes installation and disassembly simple, convenient and quick.

[0029] In this application, the housing can be the housing of wearable devices, alarms, or other electronic devices, and there is no limitation on this.

[0030] The following is combined with Figures 1 to 8 The present application will be further described in detail with reference to specific embodiments.

[0031] like Figures 1 to 3 As shown, the waterproof button sleeve 1 of this application includes a base pad 11, which is used to contact the circuit board of the housing, for example, the circuit board presses against the base pad 11. At least one set of sealing rings 12 and button caps 13 are provided on the outer surface of the base pad 11. In some embodiments, the waterproof button sleeve 1 of this application provides a set of sealing rings 12 and button caps 13 on the outer surface of the base pad 11. In other embodiments, the waterproof button sleeve 1 of this application provides two sets (e.g., sealing rings 12 and button caps 13) on the outer surface of the base pad 11. Figures 1-3 (As shown) There may even be multiple sets of sealing rings 12 and button caps 13, with specific settings adapted to the number of buttons.

[0032] Combination Figure 1 , Figure 2 As shown, the upper surface of the button cap 13 is higher than the upper surface of the sealing ring 12. The sealing ring 12 is set around the button cap 13, and a gap 14 is left between the outer periphery of the button cap 13 and the inner periphery of the sealing ring 12. Setting the upper surface of the button cap 13 to be higher than the upper surface of the sealing ring 12 allows the waterproof button sleeve 1 to only expose the part of the button cap 13 after installation, so that the user can press the button cap 13 when using it (thereby further controlling the button below the button cap 13) without affecting the sealing ring 12 (for example, if the upper surface of the button cap 13 is the same height as the upper surface of the sealing ring 12, after the sealing ring 12 is fixed by compression after installation, the upper surface of the button cap 13 is still inside the housing and cannot be exposed for the user to use).

[0033] Furthermore, such as Figure 2 , Figure 3 As shown, a button cavity 15 corresponding to the button cap 13 is provided on the inner surface of the base pad 11, and a protrusion 16 is also provided on the inner surface of the base pad 11. The button cavity 15 is used to accommodate the button. When the button cap 13 is pressed, the protrusion 16 on its inner surface (i.e., the top surface of the button cavity 15) will contact the button, and the button will be pressed down, realizing the button pressing operation. When the finger is lifted, the button cap 13 elastically returns to its original position, and the protrusion 16 on the inner surface of the button cap 13 will either disengage from or just contact the button, without pressing the button, realizing the button disengagement operation.

[0034] The waterproof button sleeve 1 of this application is integrally molded and made of a flexible waterproof material. For example, flexible waterproof materials such as silicone, rubber, and polyethylene-polypropylene composite waterproof membrane are used. The flexible material allows the waterproof button sleeve 1 to undergo elastic deformation when the button cap 13 is pressed, thereby pressing the button located in the button cavity 15.

[0035] Furthermore, the sealing ring 12 is accommodated in an annular groove on the housing, and the elastic deformation of the sealing ring 12 can achieve a seal along the sidewall of the annular groove. This will be further explained below in conjunction with the housing structure.

[0036] In this embodiment, as Figures 1 to 3 As shown, this application provides two sets of sealing rings 12 and button caps 13 on the outer surface of the base pad 11, with the two sets of sealing rings 12 and button caps 13 arranged side by side; correspondingly, two buttons are provided at corresponding positions inside the housing.

[0037] refer to Figures 4 to 8 Based on the same inventive concept, this application also provides a housing 2, which is used to be adapted to the waterproof button pad 1 described above.

[0038] Specifically, such as Figure 4 As shown, the housing 2 includes various types of housings. Here, only the partial housing at the joint with the waterproof button pad 1 is presented in this embodiment. The housing 2 is made of hard plastic, and the use of plastic housing 2 can effectively waterproof the surface. This application does not limit the composition and overall structure of housing 2, but focuses on the structure of housing 2 that is combined with the waterproof button pad 1.

[0039] Further reference Figure 4 , Figure 7 and Figure 8 As shown, at least one opening 213 is provided on the housing 2 to accommodate the button cap 13, and the shape of the opening 213 corresponds to the shape of the button cap 13. In this embodiment, the inner diameter of the opening 213 is larger than the outer diameter of the button cap 13, so that the button cap 13 can be pressed from outside the housing 2, thereby controlling the internal button 41 to be pressed.

[0040] Furthermore, in combination Figure 5 , Figure 6 As shown, inside the housing 2 corresponding to the opening 213 (specifically, on the inner surface of the front cover 21), there is a set of annular inner walls 214 and annular outer walls 215. The annular outer walls 215 surround the annular inner walls 214. An annular groove 216 is provided between the annular inner walls 214 and the annular outer walls 215. The width of the annular groove 216 is equal to or less than the width of the sealing ring 12, mainly because the width of the annular groove 216 is slightly smaller than the width of the sealing ring 12. Since the sealing ring 12 is an elastic material, although the width of the annular groove 216 is slightly smaller than the width of the sealing ring 12, the sealing ring 12 can be squeezed into the annular groove 216 to ensure a water seal is formed in the annular groove 216. The depth of the annular groove 216 is greater than the height of the sealing ring 12. Thus, after the sealing ring 12 is fully inserted into the annular groove 216, a certain gap can be formed between the top of the sealing ring 12 and the bottom of the annular groove 216 to accommodate a small amount of air that was not discharged in the annular groove 216 when the sealing ring 12 was pressed in. Figure 7 The sealing ring 12 shown is embedded in the annular groove 216 and maintains good water sealing performance.

[0041] The sealing ring 12 can be pressed and fixed onto the housing 2 through the annular groove 216, thus forming a connection with the housing 2, making installation simple. After the waterproof button sleeve 1 is installed on the housing 2, it... Figure 7 and Figure 8 As shown.

[0042] Further reference Figure 7 and Figure 8 The housing 2 also includes a circuit board 4, on which at least one protruding button 41 is provided. The position of the button 41 on the circuit board 4 corresponds to the button cavity 15 of the waterproof button sleeve 1. When the circuit board 4 is fixedly installed inside the housing 2, the button 41 is housed within the button cavity 15 of the waterproof button sleeve 1.

[0043] Specifically, in combination Figure 6 , Figure 7 , Figure 8 As shown, two slots 218 are provided on the inner surface of the front cover 21. The circuit board 4 is fixed in the housing 2 by means of the slots 218 and the snap fasteners, so that one side of the circuit board 4 abuts against the bottom of the waterproof button pad 1. There is no limitation on the fixing method of the circuit board 4, and other methods can also be used, such as screw fixing.

[0044] The bottom of the waterproof keypad 1 contacts the circuit board 4. The side of the circuit board 4 with the key 41 presses against the bottom of the waterproof keypad 1, squeezing the bottom pad 11 of the waterproof keypad 1. After the circuit board 4 is fixed to the housing 2, the circuit board 4 presses the sealing ring 12 into the annular groove 216, making the waterproof keypad 1 more firmly installed on the housing 2, producing a further waterproof sealing effect. The key 41 is housed in the key cavity 15 of the waterproof keypad 1, preventing water from entering the housing 2 and causing corrosion or damage to the internal circuitry.

[0045] In this embodiment, combined with Figures 1 to 8 As shown, to correspond with the waterproof button sleeve 1 (where the outer surface of the bottom pad 11 of the waterproof button sleeve 1 is provided with two sets of sealing rings 12 and button caps 13, arranged side by side), two openings 213 are made on the housing 2. Each opening 213 corresponds to a set of annular inner walls 214 and annular outer walls 215 inside the housing 2. The annular outer walls 215 of the same set surround the annular inner walls 214, and an annular groove 216 is provided between the annular inner walls 214 and the annular outer walls 215 of the same set to accommodate the sealing rings 12. Correspondingly, two buttons 41 are provided on the circuit board 4.

[0046] Therefore, this application discloses a waterproof keypad and housing. The waterproof keypad includes a base pad, at least one set of sealing rings and a keycap on the outer surface of the base pad, the upper surface of the keycap being higher than the upper surface of the sealing rings, the sealing rings surrounding the keycaps, and a gap between the outer periphery of the keycaps and the inner periphery of the sealing rings. A key cavity corresponding to the keycaps is provided on the inner surface of the base pad. The waterproof keypad of this application is made of waterproof material and is integrally molded. When used with the housing, the keycaps inside the housing are accommodated by the key cavity, and the sealing rings tightly accommodate the keycaps within the space between the annular inner wall and the annular outer wall of the housing, effectively preventing water ingress into the housing and protecting the internal components. During use, it can be fixed to the housing for waterproof sealing without the need for adhesives or screws. The installation and removal of the waterproof keypad on the housing are simple, convenient, and quick, while also providing excellent sealing performance.
