[0029] In order to solve the problem in the related art that the waterproof performance of the charging device matched with the button is reduced due to the reduced waterproof performance of the button, on the first hand, referring to Figures 1 to 3, an embodiment of the present application provides a button 200 waterproof structure, which is applied to the matching button 200, the button 200 includes a key cover 210 and a push switch 220, the button 200 waterproof structure includes an elastic seal 100, one side of the elastic seal 100 is used to connect with the key cover 210, and the other side of the elastic seal 100 is used to connect with the push switch 220, and sealing reinforcements 110 are provided at both ends of the elastic seal 100, and the sealing reinforcements 110 are used to tightly connect the elastic seal 100 and a carrier matched with the button 200.

[0030] Among them, the carrier matched with the button 200 mainly refers to the carrier that is electrically connected to the button 200. When the button 200 is pressed, the carrier can be started or the current operation mode of the carrier can be switched. In this embodiment, the carrier matched with the button 200 takes the charging device 300 as an example. The elastic seal 100 is made of silicone or rubber, which has good elasticity, sealing and corrosion resistance. The sealing reinforcement 110 is integrally manufactured with the elastic seal 100 to ensure the tightness and sealing of the connection between the sealing reinforcement 110 and the elastic seal 100. The material of the sealing reinforcement 110 is consistent with the material of the elastic seal 100.

[0031] Specifically, the button 200 waterproof structure is installed between the key cover 210 and the push switch 220 to form a button 200 with good waterproof performance, and then the button 200 is installed on the charging device 300 to improve the waterproof performance of the charging device 300.

[0032] In this embodiment, the elastic seal 100 is used to ensure the tightness and sealing of the key cover 210 and the push switch 220 when they are connected, and the sealing reinforcement 110 is used to improve the tightness and sealing of the elastic seal 100 and the carrier matched with the button 200 when they are connected, which helps to improve the tightness and sealing of the connection between the button 200 and the carrier, and further improve the waterproof performance of the carrier matched with the button 200, such as the charging device 300.

[0033] 4 , in some embodiments, a plurality of outer grooves 120 are provided on one side of the elastic seal 100 for connecting with the key cover 210 , and the outer grooves 120 are used to be engaged with the stopper 214 preset on the key cover 210 .

[0034] Among them, the outer groove 120 has two groove surfaces, and the two groove surfaces form a step, that is, the circumferential ring of the elastic seal 100 is provided with multiple steps, and the preset stop part 214 on the key cover 210 is integrally formed with the key cover 210, and the stop part 214 is engaged with the outer groove 120.

[0035] Specifically, after one side of the elastic seal 100 is installed with the push switch 220, the other side of the elastic seal 100 is installed with the key cover 210 through the engagement of the outer groove 120 with the stopper 214, thereby assembling to form a button 200 with good waterproof performance.

[0036] 3 and 4 , in some embodiments, the elastic sealing member 100 is used to surround a side connected to the push switch 220 to form a receiving groove 140, and the diameter of the groove wall of the receiving groove 140 opposite to the displacement direction of the button 200 is larger than the cross-sectional diameter of the push switch 220, so that when a force is applied to the push switch 220 along its displacement direction, the pressure on the top of the push switch 220 can be reduced, thereby providing a certain buffering protection for the push switch 220 and helping to ensure the service life of the push switch 220.

[0037] In addition, a step portion 142 is provided on the groove wall on the peripheral side of the accommodating groove 140, and the height of the step portion 142 is smaller than the height of the step formed by the above-mentioned outer groove 120, and the step portion 142 is recessed toward the outside, so that the space inside the accommodating groove 140 is larger, so that when the button 200 is pressed downward along the displacement direction of the button 200, the elastic seal 100 is compressed more evenly, thereby ensuring the sealing of the button 200; and the larger accommodating groove 140 also helps to provide a larger resilience for the button 200, thereby helping to improve the feedback when the button 200 is pressed.

[0038] 3 and 4 , in some embodiments, a surface of the elastic sealing member 100 at one end close to the key cover 210 is parallel to an outer surface of the key cover 210 at a side away from the push switch 220 .

[0039] Specifically, the end of the elastic seal 100 close to the key cover 210 is the end of the elastic seal 100 that is opposite to the displacement direction of the button 200 and away from the press switch 220. The surface of the end of the elastic seal 100 close to the key cover 210 is set to be a surface parallel to the outer surface of the key cover 210 away from the press switch 220, which can ensure that the pressing feeling of the button 200 is consistent, thereby ensuring that the user can get better feedback and feel when pressing the button 200.

[0040] 3 and 4 , in some embodiments, the sealing reinforcement member 110 includes a sealing ridge, and the sealing ridge is used for interference fit with a sealing groove 310 preset on the carrier.

[0041] The housing of the carrier is provided with a mounting portion 342 for accommodating the button 200 including the waterproof structure. The button 200 and the waterproof structure adapted thereto can be stably connected to the carrier by cooperating with the mounting portion 342. The sealing groove 310 is arranged around the outer side of the mounting portion 342. The extending direction of the sealing groove 310 is parallel to the displacement direction of the button 200 when pressed. The bottom end of the sealing groove 310 is connected to the mounting portion 342. The top surface of the sealing groove 310 is parallel to the outer top wall of the key cover 210. The length of the sealing groove 310 is longer than the length of the sealing convex ridge.

[0042] Specifically, when the key cover 210 is not squeezed by external force and is in a static state, the top of the sealing ridge is inserted into the sealing groove 310 and has an interference fit with the sealing groove 310, which helps to improve the sealing between the elastic seal 100, the push switch 220 and the matching charging device 300; when the key cover 210 is subjected to downward pressing force, the elastic seal 100 also presses the push switch 220 downward. Since the elastic seal 100 has a certain flexibility, the sealing ridge extends toward the top side of the sealing groove 310, that is, the elastic seal 100 is deformed; when the applied pressing force disappears, under the action of elastic deformation, the elastic seal 100 recovers under the action of its own resilience and applies a reverse force to the key cover 210, thereby helping to reset the key cover 210.

[0043] In this embodiment, the interference fit between the sealing ridge and the sealing groove 310 helps to further improve the sealing performance between the elastic sealing member 100 , the button 200 and the charging device 300 .

[0044] 3 and 4 , in some embodiments, a deformation buffer groove 130 is formed between the sealing reinforcement member 110 and the elastic sealing member 100 , and the deformation buffer groove 130 is used for interference fit with a protrusion 320 preset on the carrier.

[0045] Specifically, the connection between the sealing reinforcement 110 and the elastic sealing member 100 is a smooth inclined surface, that is, the bottom of the deformation buffer groove 130 is an inclined surface, and the height of the inclined surface gradually increases from the sealing reinforcement 110 to the elastic sealing member 100. The protrusion 320 preset on the carrier is a protrusion 320 preset on the housing 340 of the charging device 300 near the mounting portion 342. The protrusion 320 and the housing 340 are integrally formed, and the end surface of the protrusion 320 and the deformation buffer groove 130 is provided with a rounded corner, and the rounded corner is pressed against the inclined surface. When the elastic sealing member 100 moves downward under the pressing force, the sealing ridge moves toward the top of the sealing groove 310 under the cooperation of the deformation buffer groove 130 and the protrusion 320, thereby ensuring the sealing and waterproof performance during the pressing process; when the pressing force is withdrawn, under the action of the deformation buffer groove 130, the sealing ridge drives the elastic sealing member 100 to reset together.

[0046] 3 , in some embodiments, a rounded corner or chamfer 312 is provided at one end of the sealing ridge that is interference-fitted with the sealing groove 310 .

[0047] Specifically, the end of the sealing ridge that is interference-fitted with the sealing groove 310 is chamfered or rounded 312 to reduce the resistance and friction of the sealing ridge when it moves in the sealing groove 310, thereby better ensuring the feel when pressing the button 200.

[0048] The button waterproof structure in the present application ensures the tightness and sealing of the key cover 210 and the push switch 220 when they are connected through the elastic seal 100, and improves the tightness and sealing of the elastic seal 100 and the carrier matched with the button 200 when they are connected through the sealing reinforcement 110, which helps to improve the tightness and sealing of the connection between the button 200 and the carrier, and further improves the waterproof performance of the carrier matched with the button 200, such as the charging device 300.

[0049] In the second aspect, referring to FIG. 3 , an embodiment of the present application provides a button 200, comprising any one of the waterproof structures of the button 200 provided in the first aspect, wherein the button 200 further comprises a key cover 210 and a push switch 220, wherein an elastic seal 100 is disposed between the key cover 210 and the push switch 220, and the push switch 220 is connected to a carrier matching the button 200 via a connector 400.

[0050] 3 , in some embodiments, the connector 400 includes a fixing plate, and one end of the push switch 220 away from the elastic seal 100 is fixedly connected to the fixing plate, and the fixing plate is fixedly disposed in the charging device.

[0051] Specifically, the fixing plate can be a PCB (Printed Circuit Board) board, which is a substrate for supporting and connecting electronic components. The end of the push switch 220 away from the elastic seal 100 is fixedly connected to the PCB board, and the PCB board is fixedly connected in the charging device 300. The PCB board is used to achieve a stable connection between the push switch 220 and the charging device 300. In addition, with the cooperation of the shell 340 of the charging device 300 located on one side of the mounting portion 342, after the button 200 with the elastic seal 100 is installed on the charging device 300, the elastic seal 100 has a certain deformation in the initial state, and the elastic deformation preload is 0.25 mm, which can always give the button 200 an upward holding force and a downward preload, thereby helping to improve the pressing feel of the button 200; and helping to ensure the sealing and waterproofness of the connection between the button 200 and the charging device 300.

[0052] 3 and 4 , in some embodiments, the outer surface of the key cover 210 away from the push switch 220 is a first smooth inclined surface 216 , and the surface of the elastic seal 100 close to the end cover is a second smooth inclined surface 150 parallel to the first smooth inclined surface 216 .

[0053] Specifically, the household charging device 300 in the charging device 300 is relatively small, and the outer surface of the housing 340 located on the side of the button 200 is mostly a smooth arc surface, so that the user can hold or pick it up. The outer surface of the key cover 210 away from the pressing switch 220 is set as the first smooth inclined surface 216, which helps to reduce the possibility of the key cover 210 being hit by external forces or scratched by foreign objects due to protruding from the surface of the housing 340 of the charging device 300, thereby playing a certain role in anti-collision protection for the key cover 210. The surface of the elastic seal 100 close to the end cover is set as the second smooth inclined surface 150 parallel to the first smooth inclined surface 216, which helps to ensure the tight connection between the elastic seal 100 and the key cover 210, and can effectively prevent external dust, water vapor or other impurities from entering the interior of the button 200; and can ensure the consistency of the pressing feeling of the button 200, and improve the user's feel when pressing the button 200.

[0054] 1 and 3 , in some embodiments, the outer peripheral side wall of the key cover 210 is engaged with the limiting groove 330 reserved on the carrier.

[0055] Specifically, the limiting groove 330 is located at the top of the mounting portion 342. The limiting groove 330 helps to guide the displacement process of the key cover 210, thereby ensuring the stability of the key cover 210 when applying the pressing force to the press switch 220. Moreover, as can be seen from FIG. 3 , the cross-sectional diameter of the top of the key cover 210 is smaller than the cross-sectional diameter of the bottom of the key cover 210. Accordingly, the cross-sectional diameter of the top of the limiting groove 330 is smaller than the cross-sectional diameter of the bottom of the limiting groove 330. Such a setting ensures that after the key cover 210 is embedded in the housing 340, even under the action of the elastic restoring force generated by the elastic seal 100, the key cover 210 will not protrude from the outer surface of the housing 340, thereby helping to ensure the tightness and stability of the connection between the key cover 210 and the housing 340.

[0056] The button 200 in the present application has good sealing and waterproof properties because it has the above-mentioned button waterproof structure; and under the limiting action of the fixing plate and the shell 340 of the matching charging device 300, the internal elastic seal 100 has a certain elastic deformation in the initial state, that is, when not subjected to pressing force, so that it can always provide the key cover 210 with an upward holding force and a downward pre-pressure, thereby improving the user's feel when pressing the button 200.

[0057] In the third aspect, referring to Figures 1 to 4, an embodiment of the present application provides a charging device 300, including any button 200 waterproof structure provided in the first aspect and any button 200 provided in the second aspect, the charging device 300 also includes a shell 340, the shell 340 is provided with a mounting portion 342 for mounting the button 200, the mounting portion 342 is provided with a positioning groove, the key cover 210 is provided with a positioning ridge 212, and the positioning ridge 212 is slidably connected to the positioning groove.

[0058] According to the above content, a mounting portion 342 for mounting the button 200 is provided on the housing 340 , the sealing groove 310 is arranged around the circumference of the mounting portion 342 and communicated with the mounting portion 342 , and the positioning groove is arranged on the side of the mounting portion 342 .

[0059] Specifically, after the elastic seal 100 and the push switch 220 are connected, when the key cover 210 is installed, the cooperation between the positioning ridge 212 and the positioning groove facilitates the worker to quickly assemble the key cover 210 and the elastic seal 100 .

[0060] Since the charging device 300 in the present application is provided with the button 200 with good sealing and waterproof properties, the mounting portion 342 thereof also has good sealing and waterproof properties, and the other parts of the shell 340 are almost integrally formed or provided with sealing rings and waterproof plug structures at the connection locations, the charging device 300 in the present application also has good sealing and waterproof properties.

[0061] In the description of this specification, the description with reference to the terms "some embodiments", "other embodiments", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic description of the above terms does not necessarily refer to the same embodiment or example.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
