Description

Technical Field

[0001] This utility model relates to the field of headphones, and in particular to a decorative charging module for wireless headphones. Background Technology

[0002] Existing wireless earphones typically consist of an ear stem and a housing. The housing houses the speaker, while the ear stem usually has a cavity for mounting the PCB board and charging pins. However, in practice, the charging pins are quite small, making installation cumbersome. Current methods generally involve injection molding the pins and bottom cover as a single piece, then electrically connecting them to the PCB board. Therefore, this structure places high demands on the injection molding process, resulting in a homogenization of existing bottom cover designs and impacting product distinctiveness.

[0003] The earpiece can be referenced in Chinese patent CN202330291139.6. Summary of the Invention

[0004] The main purpose of this invention is to propose a decorative charging module for wireless earphones. The charging structure is designed as a long, block-shaped structure that is electrically connected to a PCB board. The charging structure can serve as both a charging terminal and a decorative cover, thereby improving the product's recognizability.

[0005] To achieve the above objectives, this utility model proposes a decorative charging module for wireless earphones, comprising:

[0006] A terminal, wherein the terminal is made of a conductive material or the terminal is partially coated with a conductive layer, the terminal comprising a positive terminal and a negative terminal;

[0007] An isolation element is provided between the positive and negative ends;

[0008] The terminal is used to install on and cover the lower end of the ear rod.

[0009] In actual design, the terminal is directly used as the bottom cover of the ear rod and installed and fixed. Therefore, in actual design, the bottom cover of the ear rod can be a partial metal layer structure or a complete metal layer structure, and then the PCB board or lithium battery is charged through the terminal. At the same time, when the terminal is partially conductive, it can have a more obvious metallic luster, thereby improving the recognition of the earphone and reducing the problem of terminal injection molding.

[0010] At the same time, compared with existing charging pins, it can provide a larger charging area, thereby improving charging efficiency;

[0011] In one embodiment, the positive and negative terminals consist of two terminals, which are separated by adhesive or a insulating layer.

[0012] In another embodiment, the terminal can also be an integral structure, with a conductive layer partially covered or provided, thereby allowing current from outside the ear rod to enter the cavity of the ear rod, thereby enabling the earphone's battery to be charged.

[0013] In another embodiment, electrical isolation is achieved between terminals via a plastic component, and installation is simpler.

[0014] In this design, the terminal serves as both a bottom cover and a charging structure, combining the functions of a charging device with a decorative effect. Attached Figure Description

[0032] like Figures 1 to 5 As shown, a decorative charging module for wireless earphones includes:

[0033] Terminal 1, wherein the terminal 1 is made of a conductive material or wherein a conductive layer is partially coated on the terminal 1, the terminal 1 comprising a positive terminal 11 and a negative terminal 12;

[0034] An isolation element 2 is provided between the positive end 11 and the negative end 12;

[0035] The terminal 1 is used to install on and cover the lower end of the ear rod.

[0036] In the actual design, terminal 1 is directly used as the bottom cover of the ear rod and installed and fixed. Therefore, in the actual design, the bottom cover of the ear rod can be a partial metal layer structure or a complete metal layer structure, and then the PCB board 5 or lithium battery can be charged through terminal 1. At the same time, when the part of terminal 1 is a conductive layer, it can have a more obvious metallic luster, thereby improving the recognition of the earphone and reducing the injection molding problem of terminal 1.

[0037] At the same time, compared with existing charging pins, it can provide a larger charging area, thereby improving charging efficiency;

[0038] In one embodiment, the positive terminal 11 and the negative terminal 12 are composed of two terminals 1, and the terminals 1 are separated by adhesive or a insulating layer, thereby achieving separation of the positive and negative terminals;

[0039] In another embodiment, terminal 1 can also be an integral structure, with partial coverage or a conductive layer provided, thereby enabling the current outside the ear rod to extend into the cavity of the ear rod, thereby enabling the charging of the earphone's battery.

[0040] In another embodiment, electrical isolation is achieved between terminals 1 via a plastic component, and installation is simpler.

[0041] In this design, terminal 1 serves as both a bottom cover and a charging structure, combining the functions of a charging structure with a decorative effect.

[0042] Specifically, the isolating element 2 is an insulating layer or insulating adhesive. In actual installation, when both ends 1 are integral metal parts, the two can be separated by insulating adhesive or insulating layer, and the two ends 1 can be positioned and fixed by the lugs.

[0043] In this embodiment of the utility model, the isolating member 2 is a plastic shell 20, and the terminal 1 is provided in two parts. The two terminals 1 are detachably installed on the plastic shell 20, that is, the plastic shell 20 is used as a bridging member for installation. The engagement between the bottom cover and the ear rod of this application can be fixed by fixing the plastic shell 20 and / or by setting an engagement structure on the terminal 1.

[0044] Specifically, the lower wall of terminal 1 is a decorative surface, wherein the decorative surface may be a metal layer (e.g., an electroplated layer).

[0045] In this embodiment of the utility model, the plastic shell 20 is provided with symmetrically arranged through holes 31, and the terminal 1 is provided with a locking post 32 that cooperates with the through hole. The locking post 32 passes through the through hole 31 and extends into the upper wall of the plastic shell 20. The two locking posts 32 form a clamping groove 33. The two ends of the PCB board 5 are provided with gold fingers that cooperate with the locking post 32 to achieve electrical contact.

[0046] Specifically, a clamping groove 33 is formed between the two locking posts 32. The clamping groove 33 is provided with a PCB board 5. The position where the locking posts 32 contact the PCB board 5 is a conductive part. The position where the PCB board 5 contacts the conductive part is provided with gold fingers. Therefore, in actual installation, the terminal 1 and the PCB board 5 can achieve conductivity even without soldering.

[0047] In this embodiment of the utility model, the upper end of the locking post 32 is provided with a locking hook 4. After the locking post 32 passes through the through hole 31, the locking hook 4 abuts against the upper wall of the plastic shell 20, thereby realizing the installation and fixation of the terminal 1.

[0048] Specifically, the outer wall of the plastic shell 20 is provided with a guide groove 41, and the terminal 1 is provided with a guide post 42 that cooperates with the guide groove 41. The installation and fixation between the plastic shell 20 and the two terminals 1 can be realized through the cooperation of the locking post 32 and the guide post 42 and the snap-fit ​​structure.

[0049] In this embodiment of the invention, the cross-section of the lower end of the terminal 1 is semi-circular, arc-shaped, or ring-shaped;

[0050] The terminal 1 is made of iron and aluminum alloy and has an electroplated layer. The specific electroplated layer can realize the structure of the terminal 1 as a decorative bottom cover, which can ensure both charging and aesthetics and recognizability.

[0051] Specifically, the terminal 1 includes a bottom wall 101 and an end wall 102 that extends upward in an arc from the outside of the bottom wall, thus allowing for a larger metal area. Of course, the middle part of the terminal 1 can also be provided with a relief groove, a solid structure, etc., to meet different design requirements.
