Description

Technical Field

[0001] This application belongs to the field of smart wearable technology, specifically relating to a watch. Background Technology

[0002] The charging pin is a crucial component for charging and data transfer in a watch. It must be insulated from the watch case and be waterproof. To ensure waterproofing, the charging pin requires a seal; however, there is a risk of improper installation or detachment of the seal, which could compromise its waterproofing. Utility Model Content

[0003] To address the aforementioned technical issues, this application provides a watch and a smart wearable component, which aims to at least partially insulate the charging pin from the watch casing and provide waterproofing while simplifying the assembly process.

[0004] The technical solution of this application is as follows: a watch, the watch comprising: a housing, the side wall of the housing having an assembly channel, the side wall of the assembly channel being recessed to form a limiting groove, the limiting groove being disposed at one end of the assembly channel near the outer side of the housing; a charging pin, at least partially disposed within the assembly channel, and the charging pin being exposed through the assembly channel; a sealing member, sleeved on the charging pin and disposed within the assembly channel to separate the charging pin from the housing, the sealing member being elastic, and a portion of the sealing member being compressed and placed within the limiting groove.

[0005] The watch provided in this application features a sealing element fitted over the charging pin and positioned within the assembly channel. Specifically, the sealing element is positioned between the side wall of the assembly channel and the charging pin to separate the charging pin from the housing. Furthermore, the sealing element is elastic, with a portion compressed into a limiting groove. This limiting groove restricts the position of the sealing element, keeping it between the side wall of the assembly channel and the charging pin, preventing the risk of incomplete assembly or detachment and ensuring the waterproof function of the charging pin. Additionally, since the limiting groove is located at the end of the assembly channel near the outer side of the housing, the sealing element can be quickly assembled from the outside of the housing to the side wall of the assembly channel and the charging pin, and compressed into the limiting groove, ensuring efficient product assembly.

[0006] In some embodiments, the seal is interference-fitted between the sidewall of the assembly channel and the charging pin.

[0007] In some embodiments, multiple limiting grooves are provided along the axial direction of the assembly channel, and the seal is squeezed to fill multiple limiting grooves.

[0008] In some implementations, the limiting groove is annular or spiral.

[0009] In some implementations, the seal is made of an insulating seal material.

[0010] In some implementations, the seal is made of thermoplastic polyurethane.

[0011] In some embodiments, the sidewall of the assembly channel is provided with a step, which divides the assembly channel into a first channel and a second channel. The first channel and the second channel are arranged sequentially from the outside of the housing to the inside of the housing, and the step surface faces the outside of the housing. The charging pin has a contact portion, which is disposed in the first channel and exposed through the first channel. The contact portion rests on the step surface. The watch also includes an insulating member, which is disposed between the contact portion and the step surface and is sleeved on the charging pin.

[0012] In some implementations, the sidewall of the first channel is recessed to form the limiting groove, and the sealing element is sleeved on the contact portion and disposed within the first channel.

[0013] In some embodiments, the seal is pressed against the insulator.

[0014] In some implementations, the assembly channel is provided with a bevel at the end facing the outside of the housing. Attached Figure Description

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0039] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture.

[0040] The following disclosure provides numerous different embodiments or examples for implementing various mechanisms of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0041] With the development of science and technology, various wearable devices have emerged, gaining popularity due to their portability and multifunctionality, especially smartwatches. In related technologies, a charging port is typically located on the back of the watch, through which a charging pin, connected to a power source, extends to connect to the charger for charging. However, during use, the back of the watch is frequently in contact with the body and is easily corroded by sweat or water, potentially leading to charging failure or leakage. Therefore, related technologies require the watch to be waterproof, meaning a seal must be maintained between the charging pin and the watch case. Additionally, since the watch case may be made of metal, the charging pin needs to be insulated from the case to enable charging functionality.

[0042] Figure 1 A partial cross-sectional schematic diagram of a watch in related technologies is shown. Combined with... Figure 1The mobile phone includes a housing 100', which has an assembly channel 102'. A support protrusion 104' extending into the assembly channel 102' is provided on the sidewall of the assembly channel 102'. At least a portion of a charging pin 200' is disposed within the assembly channel 102' and passes through the support protrusion 104'. The support protrusion 104' has a first end facing the head of the charging pin 200' and a second end facing the tail of the charging pin 200'. A second end is provided between the head of the charging pin 200' and the first end of the support protrusion 104'. An insulating gasket 300' is provided between the inner circumferential surface of the charging pin 200' and the support protrusion 104'. A second insulating gasket 500' is provided between the tail of the charging pin 200' and the second end of the support protrusion 104'. In addition, a welding gasket 600' is provided between the tail of the charging pin 200' and the assembly channel 102'. The welding gasket 600' is located on the side of the second insulating gasket 500' facing away from the second end of the support protrusion 104'. The tail of the charging pin 200' is welded to the welding gasket 600'.

[0043] In the watch of the related technology, the first insulating gasket 300' and the second insulating gasket 500' can insulate the charging pin 200' and the housing 100', the seal 400' can provide waterproofing, and the welding gasket 600' can fix the charging pin 200' and prevent the charging pin 200' from falling off.

[0044] In related technologies, the assembly of the charging pin 200' requires four auxiliary components (first insulating gasket 300', second insulating gasket 500', welding gasket 600', and sealing element 400'), and the tail of the charging pin 200' also needs to be welded to the welding gasket 600' (e.g., laser welding), which is costly and involves complex assembly processes. In addition, the surface of the charging pin 200' oxidizes and produces welding slag during welding, which may affect the pin's conductivity. Furthermore, if waterproofing or conductivity issues are found after the charging pin 200' is assembled and welded, repairs require scrapping both the charging pin 200' and the welding gasket 600', resulting in high repair costs. Moreover, if the problem is found in the entire device, the product must be disassembled before repairs can be performed. Finally, there is a risk that the sealing element 400' may not be properly assembled or may fall off, affecting the waterproofing function of the charging pin.

[0045] To address the aforementioned technical issues, this application provides a watch that avoids the risk of improper assembly or detachment of the sealing components, thus ensuring the waterproof function of the charging pin. The specific details of the watch are now further described in conjunction with the accompanying drawings.

[0046] Figure 2 A schematic diagram of the structure of a watch according to one or more embodiments of this application is shown. Figure 3 It shows Figure 2 A top-down view. Figure 4 It shows Figure 3 A schematic diagram of the AA cross section. Figure 5 It shows Figure 4 An enlarged view of point A. For clarity, Figure 2 The watch shown only retains the case 100, omitting the rest of the watch components. (Combined) Figures 2-5 The watch provided in this application includes a housing 100, a charging pin 200, an insulating component 400, and a sealing component 300. The side wall of the housing 100 is provided with an assembly channel 104, and the side wall of the assembly channel 104 is recessed to form a limiting groove 108. The limiting groove 108 is disposed at one end of the assembly channel 104 near the outer side of the housing 100. At least a portion of the charging pin 200 is disposed within the assembly channel 104, and the charging pin 200 is exposed through the assembly channel 104. The sealing component 300 is sleeved on the charging pin 200 and disposed within the assembly channel 104 to separate the charging pin 200 from the housing 100. The sealing component 300 is elastic, and a portion of the sealing component 300 is squeezed into the limiting groove 108.

[0047] The watch provided in this application has an assembly channel 104 on the side wall of the housing 100. At least a portion of the charging pin 200 is disposed within the assembly channel 104, and the charging pin 200 is exposed through the assembly channel 104. Therefore, the exposed charging pin 200 can connect with the power supply section of the charger to charge the power source inside the housing 100. Furthermore, since the sealing member 300 is sleeved on the charging pin 200 and disposed within the assembly channel 104, that is, between the side wall of the assembly channel 104 and the charging pin 200, the charging pin 200 is separated from the housing 100, maintaining a seal between the side wall of the assembly channel 104 and the charging pin 200. Because the sealing member 300 is elastic, a portion of the sealing member 300 is compressed and placed within the limiting groove 108. Therefore, the position of the sealing member 300 can be limited by the limiting groove 108, allowing... The seal 300 is held between the side wall of the assembly channel 104 and the charging pin 200 to avoid the risk of the seal 300 not being properly assembled or falling off, and to ensure the waterproof function of the charging pin 200. In addition, since the limiting groove 108 is set at the end of the assembly channel 104 near the outside of the housing 100, the seal 300 can be quickly assembled from the outside of the housing 100 to the side wall of the assembly channel 104 and the charging pin 200, and is squeezed into the limiting groove 108, ensuring the assembly efficiency of the product.

[0048] Combination Figures 2-4The housing 100 has a charging side 102, which has a through assembly channel 104. The assembly channel 104 has a first port 1042 and a second port 1044. The charging pin 200 can be assembled to the housing 100 from the first port 1042 of the assembly channel 104. The side wall of the assembly channel 104 is provided with a step 106, and the step surface 1062 of the step 106 faces the outside of the housing 100. The charging pin 200 includes a charging end 202 and a connecting end 204. The charging end 202 is arranged at the first port 1042 and overlaps the step surface 1062 of the step 106. The connecting end 204 is arranged in the second port 1044. An insulating rib 400 is provided between the charging end 202 and the step 106. Therefore, the insulating rib 400 can prevent the end of the charging end 202 from contacting the step 106. The seal 300 is made of an insulating elastic material, which gives it an insulating function. The seal 300 is installed between the peripheral surface of the charging end 202 and the side wall of the assembly channel 104. On the one hand, it can seal the peripheral surface of the charging end 202 and the side wall of the assembly channel 104 to achieve waterproofing. On the other hand, since the seal 300 also has an insulating function, it can insulate the peripheral surface of the charging end 202 and the side wall of the assembly channel 104, thus satisfying the insulation between the charging pin 200 and the watch case 100.

[0049] The watch provided in this application only requires one insulating component 400 and one sealing component 300 to cooperate with the charging pin 200, which can achieve the functions of insulation between the charging pin 200 and the housing 100 and waterproofing. This simplifies the assembly of the charging pin 200 on the watch housing 100 and improves assembly efficiency.

[0050] Figure 6 A schematic diagram of the charging pin 200 is shown. (Combined with...) Figure 6 The charging pin 200 includes a pin tip 206 and a contact portion 208. One end of the pin tip 206 located at the second port 1044 is defined as a connection end 204 for connecting to a power source within the housing 100. The contact portion 208 is coaxially connected to the other end of the pin tip 206 and is defined as a charging end 202. The contact portion 208 is used to connect to a mating part on a charger, thereby charging the power source within the housing 100. Furthermore, the size of the contact portion 208 is larger than the size of the pin tip 206, so that the charging pin 200 is T-shaped overall.

[0051] Figure 7 A cross-sectional structural schematic diagram of the housing 100 is shown. Figure 8 It shows Figure 7 A magnified diagram of point B. (Combined with...) Figure 5 as well as Figure 8The first port 1042 of the assembly channel 104 faces the outside of the housing 100. The first port 1042 of the assembly channel 104 serves as the entry end for component assembly. The charging pin 200 is assembled to the assembly channel 104 through the first end of the assembly channel 104 and overlaps on the step 106. The charging end 202 of the charging pin 200 is located at the first port 1042 of the assembly channel 104. The connecting end 204 of the charging pin 200 passes through the assembly channel 104 and is located inside the second end.

[0052] Combination Figure 8 The first port 1042 of the assembly channel 104 has a bevel 1049 at its edge, through which the seal 300 is assembled into the assembly channel 104. The bevel 1049 facilitates the assembly of the seal 300 within the assembly channel 104. The bevel 1049 can be chamfered or rounded, and this application does not limit this.

[0053] Combination Figure 8 The assembly channel 104 includes a first channel 1046 and a second channel 1048. The first channel 1046 and the second channel 1048 are sequentially connected from the outside of the housing 100 to the inside of the housing 100. The first channel 1046 and the second channel 1048 are arranged coaxially. The inner diameter of the first channel 1046 is larger than the inner diameter of the second channel 1048, so that a step 106 is formed at the junction of the first channel 1046 and the second channel 1048. That is, the step 106 divides the assembly channel 104 into the first channel 1046 and the second channel 1048. The charging end 202 of the charging pin 200 is gapped in the first channel 1046. That is, the contact portion 208 of the charging pin 200 is exposed through the first channel 1046, and the charging pin 200 gap passes through the second channel 1048. The connecting end 204 of the charging pin 200 is located in the second channel 1048. Since the charging pin 200 is spaced within the assembly channel 104, the charging pin 200 and the housing 100 that provides the assembly channel 104 are in an insulated state.

[0054] In some embodiments, the seal 300 is interference-fitted between the charging pin 200 and the sidewall of the mounting channel 104. Specifically, the seal 300 is interference-fitted between the circumferential surface of the connecting end 204 and the sidewall of the first channel 1046. This arrangement allows the seal 300 to fill the space between the sidewall of the first channel 1046 and the charging pin 200, providing not only waterproofing and dustproofing but also, to a certain extent, securing the charging pin 200. Furthermore, since the seal 300 also has an insulating function, it also insulates the charging pin 200 from the housing 100.

[0055] In some embodiments, since the seal 300 is elastic, during assembly, the seal 300 is first pressed into the first channel 1046, and then the charging pin 200 is assembled into the seal 300. When the charging pin 200 is assembled into the seal 300, the seal 300 undergoes elastic deformation to ensure sufficient contact between the seal 300 and the sidewall of the first channel 1046, as well as the connecting end 204 of the charging pin 200. This ensures a good sealing effect between the seal 300 and the sidewall of the first channel 1046, and between the seal 300 and the charging end 202 of the charging pin 200, improving waterproofing and securing the charging pin 200. Therefore, this application avoids the use of welding to fix the tail of the charging pin 200 to the welding pad, as is done in related technologies. This avoids the surface oxidation of the charging pin 200 and the generation of welding slag, which could potentially affect the pin conductivity of the charging pin 200.

[0056] In some embodiments, the seal 300 is an insulating seal, and the material of the seal 300 is thermoplastic polyurethane, so that the seal 300 is both elastic and insulating. In other embodiments, the material of the seal 300 may also be nitrile rubber, fluororubber, EPDM rubber, and silicone rubber, etc., and this application does not limit this.

[0057] Combination Figure 5 as well as Figure 8 The limiting groove 108 is formed on the side wall of the first channel 1046, and a portion of the seal 300 can be squeezed into the limiting groove 108. When the charging pin 200 is assembled into the seal 300, a portion of the seal 300 will deform towards the limiting groove 108 so that a portion of the seal 300 can fill the limiting groove 108, improving the reliability of the assembly of the seal 300 in the assembly channel 104, and preventing the seal 300 from popping out of the assembly channel 104, which would cause the charging pin 200 to shake and fall off.

[0058] Figure 9 A structural schematic diagram of the seal 300 is shown. (Combined with...) Figure 9 The sealing element 300 is assembled between the circumferential surface of the charging end 202 and the side wall of the assembly channel 104. The sealing element 300 is annular, and its inner diameter is slightly smaller than the outer diameter of the charging end 202 of the charging pin 200, so that the charging end 202 (contact portion 208) of the charging pin 200 can be interference-fitted into the sealing element 300, and the sealing element 200 is sleeved on the contact portion 208 and disposed in the first channel 1046. When the charging pin 200 is assembled into the sealing element 300, under the pressure of the charging pin 200, the sealing element 300 will deform towards the limiting groove 108, so that the portion of the sealing element 300d can fill the limiting groove 108 to form a limiting portion that matches the limiting groove 108, thereby improving the reliability of the sealing element 300 in the assembly channel 104.

[0059] In some embodiments, one or more limiting grooves 108 may be provided at intervals along the axial direction of the assembly channel 104, and the limiting grooves 108 may be annular or spiral. When multiple limiting grooves 108 are provided, multiple limiting parts are also formed accordingly. Through the cooperation of multiple limiting parts and limiting grooves 108, the reliability of the limiting parts being assembled in the assembly channel 104 can be improved.

[0060] Figure 10 A structural schematic diagram of the insulating component 400 is shown. (Combined with...) Figure 10 The size of the insulating member 400 is adapted to the size of the first channel 1046. The insulating member 400 overlaps the side of the step 106 facing the first port 1042 through the first channel 1046. That is, the insulating member 400 is assembled between the step surface 1062 of the step 106 and the contact part 208. The middle part of the insulating member 400 is provided with a mounting hole 402. The connecting end 204 of the charging pin 200 can pass through the mounting hole 402 with clearance or interference fit and is located in the second channel 1048. That is, the insulating member 400 is sleeved on the charging pin 200.

[0061] In the watch provided by this application, when assembling the charging pin 200, the insulating component 400 is first assembled onto the step 106 through the first channel 1046, and then the charging pin 200 is assembled into the assembly channel 104, where it is temporarily supported on the insulating component 400. Finally, the sealing component 300 is assembled into the first channel 1046. The sealing component 300 is interference-fitted between the side wall of the first channel 1046 and the charging end 202 of the charging pin 200. The sealing component 300 fixes the charging pin 200 and presses against the insulating component 400, thereby fixing the insulating component 400, preventing it from loosening, and ensuring the insulation effect between the charging pin 200 and the housing 100. In addition, it can also keep the sealing component 300 and the insulating component 400 sealed, improving the sealing effect between the charging pin 200 and the housing 100. Alternatively, the insulating component 400 can be assembled onto the step 106 through the first channel 1046 first, or the insulating component 400 can be assembled first, and then the charging pin 200 can be assembled, which can also achieve the assembly of the charging pin 200 on the housing 100.

[0062] In summary, the watch provided in this application requires only two parts (a seal 300 and an insulator 400) to achieve both insulation between the charging pin 200 and the watch case 100 and waterproofing. Therefore, it not only reduces costs but also simplifies the assembly process, making the assembly of the charging pin 200 simpler and more reliable, reducing costs and facilitating maintenance. In addition, it avoids the risk of improper assembly or detachment of the seal 300, ensuring the waterproof function of the charging pin, and has excellent practicality.
