[0032] The present invention provides a charging interface structure 100 for a handheld device, aiming to solve the technical problem of how to improve the waterproof performance of the charging interface of a handheld device. The handheld device may be an electric shaver, an electric toothbrush, a handheld fan, or a hair removal device.

[0033] In the embodiment of this utility model, please refer to Figure 1 and Figure 2 , Figure 1 A schematic structural diagram of an embodiment of a charging interface structure 100 of a handheld device according to the present invention is shown; Figure 2 FIG. 1 is a cross-sectional diagram of an embodiment of a charging interface structure 100 of a handheld device according to the present invention.

[0034] The charging interface structure 100 of the handheld device includes a bracket 10 and a charging component. The bracket 10 is provided with a mounting cavity and a socket 12 connected to the mounting cavity; the charging component includes a circuit board 21 and a charging seat 22 arranged in the mounting cavity. One end of the charging seat 22 is installed on the circuit board 21, and the other end is provided with a charging interface, and the charging interface corresponds to the socket 12; a glue space 11 is formed between the outer surface of the charging seat 22 and the cavity wall of the mounting cavity, and the glue space 11 is filled with sealant.

[0035] In this embodiment, the specific structure of the bracket 10 can vary and can be selected and designed based on actual needs, and is not specifically limited here. The mounting cavity of the bracket 10 is used to accommodate the charging assembly. The socket 12 is defined on one end wall of the bracket 10 along its length. The end of the bracket 10 facing away from the socket 12 can be closed or open, without limitation. The circuit board 21 receives external current and transmits it to the handheld device's battery to charge it. The circuit board 21 is electrically connected to the charging base 22. The charging base 22 is designed to connect to the charging cable to connect to the power source and transmit current. The charging port of the charging base 22 can be a Type-C port, a USB port, or other type of charging port. The circuit board 21 is fixed within the mounting cavity, and the charging base 22 is fixed to the circuit board 21, thereby ensuring that the charging base 22 is fixedly mounted within the mounting cavity. The charging port of the charging base 22 corresponds to the socket 12, allowing the charging cable to plug into the charging base 22 through the socket 12.

[0036] Glue space 11 is located between the outer wall of charging base 22 and the wall of the mounting cavity. Due to the shapes of bracket 10, charging base 22, and other components within bracket 10, the shape of glue space 11 is irregular. The sealant has a certain degree of fluidity before solidifying, making it easier to fill glue space 11 when the sealant is filled. After solidification, the sealant fully seals glue space 11, preventing external moisture from flowing through jack 12 to circuit board 21, thereby improving the sealing effect of the handheld device's charging interface structure 100 and thus enhancing the waterproof performance of the handheld device's charging interface structure 100. Furthermore, by allowing the sealant to be directly filled between the outer surface of the charging base 22 of the charging assembly and the wall of the mounting cavity, the sealing effect of the charging base 22 is improved while ensuring a compact structure. Compared to the method of sealing the charging base by injection-molding an insert outside the charging base 22, the overall structure can be simplified, the processing accuracy can be reduced, and thus the processing cost can be effectively reduced.

[0037] Specifically, such as Figures 2 to 4 As shown, Figure 3 This is a cross-sectional exploded view of an embodiment of a charging interface structure 100 of a handheld device according to the present invention; Figure 4 This is a cross-sectional exploded view of another embodiment of the charging interface structure 100 of the handheld device of the present invention.

[0038] Specifically, the socket 12 is set downward, and an upward glue-limiting step surface 13 is provided in the installation cavity. The top surface of the circuit board 21 is located below the glue-limiting step surface 13. A glue-containing space 11 is formed between the top surface of the circuit board 21, the cavity wall of the installation cavity below the glue-limiting step surface 13, and the charging seat 22.

[0039] In this embodiment, the glue-limiting step surface 13 extends along the circumference of the circuit board 21. A glue injection port is formed between the circuit board 21 and the cavity wall of the mounting cavity. The glue injection port is connected to the glue-receiving space 11. When filling the sealant, the sealant can be injected into the glue-receiving space 11 through the glue injection port, thereby simplifying the glue injection process. The glue-limiting step surface 13 provides a reference for the glue injection process. The sealant should be filled below the glue-limiting step surface 13 to avoid overfilling and overflowing onto other structures. This improves the convenience of the glue injection process.

[0040] Specifically, such as Figure 3 and Figure 4 As shown, the charging interface structure 100 of the handheld device further includes a decorative ring 30 disposed in the mounting cavity. One end of the decorative ring 30 is sleeved on the outside of the charging seat 22 , and the other end is exposed at the socket 12 .

[0041] In this embodiment, the decorative ring 30 can serve to decorate and reinforce the gap between the charging base 22 and the socket 12. The decorative ring 30 can be a metal decorative ring, which can be polished, bright, and have a metallic texture, so that the appearance of the socket 12 can be more beautiful. The decorative ring 30 can also strengthen the structural strength of the bracket 10 at the socket 12, preventing the end wall of the bracket 10 at the socket 12 from being easily deformed or damaged after experiencing the force of multiple charging cable plugging and unplugging processes, thereby improving the overall structural stability of the charging interface structure 100 of the handheld device. Specifically, the decorative ring 30 and the sealing ring 14 are integrally injection molded. In this way, the connection strength between the decorative ring 30 and the sealing ring 14 can be improved, and the decorative ring 30 can be prevented from loosening due to multiple plugging and unplugging of the socket.

[0042] In actual application, the decorative ring 30 includes a decorative body 31 and a decorative flange 32 connected to the decorative body 31. The inner wall of the decorative body 31 is sealed with the charging seat 22, and the decorative flange 32 is arranged on the socket 12 and is flush with the periphery of the socket 12.

[0043] For example, Figure 3 and Figure 4As shown, a sealing ring 14 is protruding from the inner wall of the mounting cavity. The sealing ring 14 is mounted around the socket 12, and the charging base 22 is inserted into the sealing ring 14. The decorative body 31 is disposed between the sealing ring 14 and the charging base 22, and the decorative body 31 is sealed with the sealing ring 14 and the charging base 22 respectively. The sealing ring 14 is protruding from the end wall of the mounting cavity where the socket 12 is located. The sealing ring 14 surrounds the end of the charging base 22 near the socket 12. The sealing ring 14 can provide a position-limiting support for the charging base 22. Therefore, when the charging cable is plugged into the charging base 22, the sealing ring 14 can support the charging base 22, preventing the charging base 22 from easily deforming or shifting under the action of force, thereby improving the structural stability of the charging interface structure 100 of the handheld device.

[0044] Specifically, such as Figure 3 and Figure 4 As shown, the handheld device charging interface structure 100 further includes a sealing ring 40. The peripheral wall of the charging base 22 is provided with a sealing groove, and the sealing ring 40 is embedded in the sealing groove. The charging base 22 and the decorative ring are sealed together through the sealing ring 40. The sealing groove extends along the circumference of the charging base 22. The sealing ring 40 can be configured as a rubber ring. The sealing ring 40 partially protrudes from the notch of the sealing groove to abut against the inner peripheral wall of the decorative body 31, thereby improving the sealing between the charging base 22 and the decorative body 31, preventing moisture from entering the interior of the charging base 22 through the gap between the charging base 22 and the decorative body 31, and further enhancing the waterproof effect of the entire socket 12.

[0045] In actual application, the height of the decorative body 31 is lower than the height of the sealing ring 14 , and the space between the inner circumferential wall of the sealing ring 14 and the outer circumferential wall of the charging base 22 is filled with sealant.

[0046] A glue-containing gap is formed between the upper end surface of the decorative ring 30, the inner circumferential surface of the sealing ring 14 and the outer surface of the charging base 22. The glue-containing gap can be filled with sealant. Therefore, the solidified sealant can not only seal the glue-containing gap to form a multi-level waterproof design for the jack 12, but also fix the decorative ring 30, so that the decorative ring 30, the sealing ring 14 and the charging base 22 are more closely matched, thereby making the charging interface structure 100 of the handheld device more compact.

[0047] For example, Figure 2 As shown, the inner wall surface of the sealing ring 14 away from the end of the jack 12 is formed with an inclined first glue guiding surface 141, the first glue guiding surface 141 faces the glue containing gap, and the distance between the first glue guiding surface 141 and the charging seat 22 increases gradually from bottom to top. The first glue guiding surface 141 can guide the sealant, so that the sealant can enter the glue containing gap faster and more fully along the first glue guiding surface 141, so as to improve the glue injection effect on the glue containing gap.

[0048] Specifically, an inclined second adhesive guiding surface 311 is formed on the inner wall surface of the decorative body 31 at the end away from the insertion hole 12. The second adhesive guiding surface 311 faces the adhesive gap, and the distance between the second adhesive guiding surface 311 and the charging base 22 gradually increases from bottom to top. The second adhesive guiding surface 311 serves to guide the sealant, allowing the sealant to enter the gap between the decorative body 31 and the charging base 22 more quickly and fully along the second adhesive guiding surface 311, thereby improving the adhesive injection effect in the gap.

[0049] For example, Figures 2 to 4 As shown, the bracket 10 has a bottom wall 15, and the socket 12 is opened on the bottom wall 15; the bottom wall 15 also has a connecting port 151, and the inner wall surface of the bottom wall 15 is provided with a surrounding plate 16 protruding around the connecting port 151; the charging interface structure 100 of the handheld device also includes a sealing cap 50, the sealing cap 50 includes a cover 51 and a connecting column 52 connected to the inner wall surface of the cover 51, and the connecting column 52 is movably arranged in the surrounding plate 16 through the connecting port 151, so that the cover 51 can open or close the socket 12 and the charging seat 22; the charging interface structure 100 of the handheld device also includes a sealing plug 60, which blocks the end of the surrounding plate 16 away from the connecting port 151.

[0050] In this embodiment, the sealing cap 50 is located on the side of the bottom wall 15 away from the installation cavity. When the charging interface structure 100 of the handheld device is in an idle state, that is, when the charging seat 22 does not need to be plugged into the charging cable, the sealing cap 50 can close the socket 12 to prevent moisture from entering the socket 12 and wetting the charging seat 22, thereby hiding and protecting the charging seat 22. The connecting column 52 cooperates with the enclosure 16 to achieve a movable connection between the sealing cap 50 and the bracket 10, making it convenient for the cover 51 to open or close the socket 12 and the charging seat 22. A limiting boss can be provided at the end of the connecting column 52, the width of which is greater than the width of the connecting port 151, so that the connecting column 52 cannot easily leave the connecting port 151, thereby ensuring the installation stability of the sealing cap 50.

[0051] The sealing plug 60 blocks the end of the enclosure 16 away from the connection port 151 to prevent the sealant from seeping into the enclosure 16 and affecting the opening and closing of the cover 51 when the glue is injected into the glue space 11. In addition, the sealing plug 60 can also prevent external moisture from entering the charging assembly through the connection port 151. When the sealing cap 50 is assembled on the bracket 10, a removable portion 53 can be reserved at the end of the connecting column 52. The removable portion 53 is connected to the connecting column 52 through a breakable structure (such as a breakable notch). When the connecting column 52 is matched with the enclosure 16, the removable portion 53 first extends into the enclosure 16 from the connection port 151, and then passes through the end of the enclosure 16 away from the connection port 151. At this time, the assembler can grab the removable portion 53 that passes through the enclosure 16 and apply tension to pull the connecting column 52 into the enclosure 16. After the connecting post 52 is properly engaged with the enclosure 16, the removable portion 53 can be broken off and removed from the connecting post 52, and the assembler then seals the sealing plug 60 on the end of the enclosure 16 away from the connection port 151. This simplifies the installation process of the sealing cap 50 and improves the installation efficiency of the sealing cap 50.

[0052] Specifically, such as Figure 3 and Figure 4 As shown, the end surface of the enclosure 16 away from the bottom end wall 15 is located between the circuit board 21 and the end surface of the sealing ring 14 away from the bottom end wall 15, and the projections of the enclosure 16 and the circuit board 21 on the bottom end wall 15 are staggered with each other.

[0053] The upper end surface of the enclosure 16 is lower than the circuit board 21 and higher than the sealing ring 14. The lower upper end surface of the enclosure 16 allows for reasonable control of the height of the enclosure 16, limiting the size of the enclosure 16 to within the adhesive space 11, thereby reducing the excessive space occupied by the enclosure 16 in the installation cavity. Simultaneously, the sealant seals and secures the end of the enclosure 16, further enhancing the stability of the connection between the sealing plug 60 and the enclosure 16. The higher upper end surface of the enclosure 16 is above the sealing ring 14, ensuring that the enclosure 16 is of sufficient size to mate with the connecting post 52, thereby improving the stability of the mating between the enclosure 16 and the connecting post 52.

[0054] A glue injection port, opposite to the enclosure 16, is formed between the circuit board 21 and the cavity wall of the mounting cavity. Sealant can be injected into the adhesive-receiving space through this port. Combined with the aforementioned embodiment of the removable portion 53, the injection port also allows the circuit board 21 to avoid the removable portion 53 during assembly of the sealing cap 50, allowing the removable portion 53 to be easily removed by the assembly personnel after it passes through the enclosure 16. After the removable portion 53 is removed, the injection port also allows the sealing plug 60 to avoid the circuit board 21 and seal against the enclosure.

[0055] The utility model also provides an electric shaver, such as Figure 5As shown, the electric shaver includes a shaver body and a handheld device charging interface structure 100. The specific structure of the handheld device charging interface structure 100 is referred to the above embodiments. Since the electric shaver adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The shaver body includes a housing 200 with an open end, and the handheld device charging interface structure 100 is installed at the opening of the housing 200.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
