[0113] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the detailed description of the present invention below, some specific details are described in detail. For those skilled in the art, the present invention can be fully understood without the description of these details. In order to avoid confusing the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0114] In addition, persons of ordinary skill in the art will appreciate that the drawings provided herein are for illustration purposes and are not necessarily drawn to scale.

[0115] Unless the context clearly requires otherwise, the words "include", "comprising" and similar words throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, the meaning is "including but not limited to".

[0116] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0117] Unless otherwise clearly defined and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0118] For ease of explanation, spatially relative terms such as "inside", "outside", "below", "below", "lower", "above", "upper", etc. are used herein to describe the relationship of one element or feature illustrated in the figures to another element or feature. It will be understood that spatially relative terms may be intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figure is turned over, an element described as being "below" or "below" other elements or features will then be positioned as being "above" the other elements or features. Thus, the example term "below" can include both the orientations of above and below. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0119] Figure 1 and Figure 2 It is a schematic diagram of the structure of the charging stand in the related art. The charging stand in the figure includes a seat body D1, a conductive spring D2, a positioning body D3, a fixing part D4 and a blocking part D5. The seat body D1 is provided with a receiving groove D11 for accommodating the earphone C and an installation cavity D12 for setting the conductive spring D2. The installation cavity D12 has a first port and a second port, and the first port and the second port are respectively facing the top and bottom of the seat body D1. During the installation process of the charging stand, it is necessary to first fix the conductive spring D2 and the positioning body D3 together, and then insert the conductive spring D2 and the positioning body D3 from the second port into the installation cavity D12 (such as Figure 2The seat body D1 is turned over so that the first port faces upward, and the conductive spring D2 is fixedly connected to the positioning body D3 and the first port by the fixing member D4. Finally, the seat body D1 is turned over again, and the second port is blocked by the blocking member D5, and fixed by the fixing member D4. When the conductive spring D2 is installed, the end of the conductive spring D2 away from the positioning body D3 will abut against the seat body D1 to prevent the conductive spring D2 from bending excessively toward the receiving groove D11. The fixing member D4 is an adhesive.

[0120] The conductive spring D2 in this embodiment extends from the first port to the second port, so that the volume occupied by the installation cavity D12 is too large, which increases the volume of the base body D1. At the same time, in order to facilitate the installation of the conductive spring D2 in the installation cavity D12, the first port and the second port are set on the installation cavity D12, and for this purpose, the first port and the second port need to be blocked respectively.

[0121] Figure 3 and Figure 4 It is a schematic diagram of the structure of the charging device of this embodiment. Figure 5 It is a cross-sectional schematic diagram of the charging device of this embodiment.

[0122] In some embodiments, Figure 3-Figure 5 As shown, the charging device in this embodiment includes two conductive arms 1 , and the conductive arms 1 are bent, and the ends of the conductive arms 1 extend into the earphone slot 22 .

[0123] Specifically, the earphone slot 22 in this embodiment is used to accommodate the earphone C. When the earphone C is placed in the earphone slot 22, the contact C1 of the earphone C can contact the conductive arm 1, and then the earphone C can be charged by the charging device. The earphone C can be a Bluetooth earphone C.

[0124] Figure 6 It is a partial schematic diagram of the charging device of this embodiment. Figure 7 It is a partial schematic diagram of the carrying portion 2 of this embodiment. Figure 8 It is a schematic structural diagram of the conductive arm 1, the positioning portion 24 and the adhesive 5 of this embodiment. Fig. 9 Schematic diagram of the structure of the conductive arm 1 and the positioning portion 24 of this embodiment.

[0125] In some embodiments, Figure 6-Figure 9 As shown, the body 4 and the positioning portion 24 in this embodiment can be made by injection molding. The material of the body 4 and the positioning portion 24 can be a polymer compound. For example, polyethylene, polyvinyl chloride, resin or rubber. The rubber can be a material such as natural rubber (NR) or nitrile butadiene rubber (NBR). When the conductive arm 1 is arranged on the bearing portion 2 through the positioning portion 24, the bearing portion 2 and the positioning portion 24 can play a better insulation role.

[0126] Fig.10 Schematic diagram of the structure of the conductive arm 1 of this embodiment.

[0127] In some embodiments, Fig.10 As shown, the conductive arm 1 in this embodiment may be made of metal, such as copper, iron, copper alloy, aluminum alloy, etc. The conductive arm 1 includes a free section 14, an electrical contact section 13, a first deformation interval 11, a second deformation interval 12, a fixed interval 15, and a feeding end 16 in the extension direction. Current can be transmitted from the feeding end 16 to the contact C1 of the earphone C through the electrical contact surface 131.

[0128] Fig.11 2 is a schematic diagram of the structure of earphone C of this embodiment.

[0129] In some embodiments, Fig.11 As shown, specifically, the earphone C in this embodiment includes an ear handle portion C3 and an earphone head C2, and the earphone head C2 is provided with a sound outlet. The ear handle portion C3 is connected to the earphone head C2. The contact C1 is provided on the ear handle portion C3, so that when the ear handle portion C3 is inserted into the earphone slot 22, the contact C1 located on the side of the ear handle portion C3 abuts against the conductive arm 1. The side surface of the ear handle portion C3 is roughly a cylinder, and the bottom surface is roughly a spherical crown.

[0130] Fig.12 , Fig.13 , Fig.14 and Fig.15 1 is a schematic diagram of the structure of the conductive arm 1 of this embodiment in different deformation states. The figure shows a partial outline of the earphone C, that is, the ear handle portion C3 of the earphone C is arranged in the earphone groove 22, and the contact C1 is arranged on the ear handle portion C3. Figure 13-Figure 15 The dotted lines in the figure show the positions of the first deformation zone 11 and the electrical contact section 13 in a free state.

[0131] Specifically, Fig.12 The earphone C in the headset is inserted into the earphone slot 22, but the earphone C does not contact the conductive arm 1. In this form, the conductive arm 1 is in a free state, the electrical contact segment 13 is located in the limiting slot 21 and the earphone slot 22 at the same time, and the electrical contact segment 13 is inclined toward the earphone slot 22. When the ear handle portion C3 continues to move downward, the bottom of the ear handle portion C3 will contact the electrical contact segment 13. That is, the first position C41 is in contact with the electrical contact segment 13. When the conductive arm 1 is in a free state, the first curved segment A1, the second curved segment A2, the third curved segment A3, the fourth curved segment A4 and the fifth curved segment A5 are all in a curved state.

[0132] Figure 12-Figure 15 The earphone C in the earphone groove 22 goes through a first stroke and a second stroke in the process from the opening end 221 to abutting against the bottom of the earphone groove 22 .

[0133] In the first trip (such as Figure 11-Figure 15 As shown in the figure, the bottom of the ear handle portion C3 (that is, the first position C41, the second position C42 and the area between the first position C41 and the second position C42) contacts the electrical contact segment 13, and the inclination amplitude of the electrical contact segment 13 increases (the angle a5 increases). At the same time, the electrical contact segment 13 moves along the radial direction of the earphone slot 22, from the earphone slot 22 to the limiting slot 21, and moves a distance in the direction away from the opening end 221.

[0134] In the second trip (such as Fig.11 and Figure 14-15 As shown), as the earphone C continues to move toward the bottom of the earphone slot 22, the end of the electrical contact segment 13 will slide toward the peripheral side surface C31 through the second position C42, and the inclination angle of the electrical contact segment 13 will decrease during this process (angle a5 decreases).

[0135] When the angle a5 is reduced to a predetermined range, the ear handle portion C3 pushes the electrical contact segment 13 so that the electrical contact surface 131 rises toward the open end 221 until the electrical contact surface 131 makes electrical contact with the contact point C1.

[0136] Alternatively, if Fig.12 As shown, a person skilled in the art can set the angle range between 50 degrees and 75 degrees. Under the downward pressure of the ear handle portion C3, the end of the electrical contact segment 13 will move a certain distance toward the bottom of the earphone slot 22, so that the inclination amplitude of the electrical contact surface 131 can be increased to avoid the earphone C.

[0137] Specifically, Fig.12 A specific configuration of the electrical contact segment 13 is shown in the figure. When the electrical contact segment 13 contacts the earphone C, it will first contact the first position C41. When the earphone C contacts the first position C41 (the conductive arm 1 is not deformed), the angle a5 between the electrical contact segment 13 and the horizontal direction is 66 degrees. Take the conductive arm 1 in a free state and the angle a5 is 66 degrees as an example. When the electrical contact segment 13 slides to the second position C42, the angle a5 between the electrical contact segment 13 and the horizontal direction becomes 72 degrees (angle a1, angle a2 and angle a3 are reduced). When the electrical contact segment 13 continues to slide from the second position C42 to the peripheral side surface C31, the angle a5 begins to decrease, that is, the inclination amplitude decreases. When the angle a5 is reduced to 53 degrees to 45 degrees, the electrical contact surface 131 of the electrical contact segment 13 will move toward the open end 221 under the push of the earphone C.

Fig.16The charging device in the figure also includes a flexible printed circuit board 263 (Flexible Printed Circuit Board), a receiving box 26 and a circuit board 82. The receiving box 26 in the figure is in a disassembled state. The receiving box 26 includes an inner lining 261 and a basin bottom 262. The circuit board 82 is arranged on the basin bottom 262, and the body 4 is arranged on the inner lining 261. The circuit board 82 is used to supply power to the feeding end 16. The flexible circuit board 263 needs to meet certain length requirements so that the operator can connect one end of the flexible circuit board 263 to the feeding end 16 and the other end to the circuit board 82. Then, the inner lining 261 is installed on the basin bottom 262. In this form, the flexible circuit board 263 is curled in the receiving box 26 to accommodate the flexible circuit board 263 through the receiving box 26.

[0142] Fig.25 Schematic diagram of the positional relationship between the body 4 and the circuit board 82 of this embodiment. The two bodies 4 of this embodiment are arranged corresponding to the same circuit board 82.

[0143] In some embodiments, Figure 17-Figure 18 As shown, the charging device includes a body 4 and a feeding unit 9. The feeding unit 9 is used to charge the earphone C through the contact C1 when the earphone C is placed on the body 4. The body 4 includes a bearing portion 2 and two side plates 6 fixedly connected to the bearing portion 2. Figure 5 As shown, the carrying part 2 has an earphone slot 22, and two side plates 6 are arranged opposite to each other. There is a gap between the two side plates 6, so that a contact plate 71 can be arranged between the two side plates 6.

[0144] Further reference Fig. 9and Fig.18 As shown, the feeding unit 9 includes a connecting portion 7 and two electrical contact surfaces 131. The electrical contact surface 131 is exposed to the inner side of the earphone slot 22, the connecting portion 7 includes two contact plates 71, the two contact plates 71 are electrically connected to the two electrical contact surfaces 131, the two contact plates 71 are respectively arranged on the two side plates 6, an insertion space 74 is formed between the two contact plates 71, and the two feeding springs 81 are configured to be inserted into the insertion space 74.

[0145] Specifically, the two contact plates 71 are respectively a positive plate and a negative plate. The charging device also includes two conductive arms 1 electrically connected to the connecting portion 7. The earphone slot 22 has two windows 222. The positions at which the two conductive arms 1 are provided with the electrical contact surfaces 131 can extend into the earphone slot 22 through the windows 222, so that when the earphone C is set in the earphone slot 22, it abuts against the two contacts C1 of the positive and negative poles of the earphone C, so that the feeding unit 9 and the earphone C can form a loop through the connecting portion 7, the two electrical contact surfaces 131 and the two contacts C1.

[0146] In summary, the charging device in this embodiment sets the electrical contact surface 131 of the conductive arm 1 in the earphone slot 22, so that when the earphone C is set in the earphone slot 22, the electrical contact surface 131 can abut against the contact C1, thereby charging the earphone C. Therefore, the two contact plates 71 are respectively set on the two side panels 6, and the electrical connection position of the electrical contact surface 131 is led out to the outside of the earphone slot 22 by the connecting part 7. So that the operator can feed current into the two electrical contact surfaces 131 when installing the charging device. Furthermore, the assembly of the charging device is simplified, and the cooperation of the main body 4 and the feeding unit 9 can adapt to different forms of installation structures. Furthermore, when the two feeding springs 81 feed the two conductive arms 1, the two side panels 6 can also play a role in supporting the contact plate 71.

[0147] In some embodiments, Fig.17 and Figure 22-Figure 23 As shown, the two contact plates 71 are respectively arranged at opposite sides of the two side plates 6 and are spaced apart. The two feeding springs 81 are respectively electrically overlapped with the two contact plates 71, and the two feeding springs 81 are bent toward opposite sides and are spaced apart.

[0148] In this embodiment, the elastic deformation of the two feeding springs 81 is utilized to electrically connect the two contact plates 71 together, thereby saving the welding process and making the connection process of the feeding part 8 and the connecting part 7 simpler.

[0149] In some embodiments, Fig.17 As shown, the feeding unit 8 further includes a circuit board 82. The circuit board 82 includes a plurality of feeding areas 821, and the feeding springs 81 are vertically arranged in the feeding areas 821. Figure 22-Figure 23As shown, the feeding spring 81 includes a sixth bending section 811 , the sixth bending section 811 has a contact surface 8111 , and the two sixth bending sections 811 are bent in directions away from each other.

[0150] When the feeding spring piece 81 is in a free state, the distance between the two abutting surfaces 8111 is greater than the distance between the two contact plates 71 , the two abutting surfaces 8111 are in abutment with the two contact plates 71 respectively, and the two feeding spring pieces 81 generate elastic bending.

[0151] When the feeding spring piece 81 is in a free state, the distance between the two abutting surfaces 8111 (distance L8) is greater than the distance between the two contact plates 71 (distance L7). When the two abutting surfaces 8111 are in abutment with the two contact plates 71, the two feeding spring pieces 81 are bent and deformed toward the opposite sides (that is, they are close to each other). In this form, the distance between the two feeding spring pieces 81 is L9. In this embodiment, the distance L9 needs to be kept greater than 0 to avoid short circuiting of the two feeding spring pieces 81 after bending.

[0152] Specifically, the feeding spring 81 has a fixed end, which is located at the end of the feeding spring 81 away from the sixth bending section 811, and the fixed end is bent and welded to the feeding area 821. This allows the feeding spring 81 to be stably arranged on the circuit board 82, and avoids the feeding spring 81 from being separated from the circuit board 82 when the feeding spring 81 is bent.

[0153] In some embodiments, such as 19- Fig. 20 As shown, the side plate 6 has a first mounting surface 62 and an edge 64 . The two first mounting surfaces 62 are arranged opposite to each other, and the edge 64 is arranged on a side of the first mounting surface 62 close to the circuit board 82 .

[0154] Further reference Fig. 22 and Fig.23 As shown, the two contact plates 71 are respectively disposed on the two first mounting surfaces 62, and the edges of the contact plates 71 cover at least a portion of the corresponding edge 64. The sixth curved section 811 further includes a guide slope 8112, which is located on a side of the abutting surface 8111 away from the circuit board 82, and the two guide slopes 8112 are inclined toward opposite sides, and when the feeding spring 81 is in a free state, the spacing between the two guide slopes 8112 is the same as the spacing between the contact plates 71 located on the two edges 64.

[0155] The operator can insert the feeding spring piece 81 from the bottom of the bearing part 2 between the two contact plates 71. During this process, the guide slope 8112 will abut against the contact plate 71 at the edge 64, so that the two feeding spring pieces 81 are bent in a direction close to each other to ensure that the sixth bending section 811 can slide between the two contact plates 71.

[0156] In some embodiments, Fig. 20 As shown, the connection portion 7 further includes two strip conductors 72, and the strip conductor 72 includes a first connection end 721, a second connection end 722, and an extension section 723 located between the first connection end 721 and the second connection end 722. The two extension sections 723 are attached to different areas of the outer side surface of the carrier portion 2, the two first connection ends 721 are respectively connected to the two contact plates 71, and the two second connection ends 722 are respectively electrically connected to the two electrical contact surfaces 131.

[0157] It is easy to understand that after the lining 261 and the basin bottom 262 are installed together, a receiving cavity is formed inside the receiving box 26. The two extension sections 723 in this embodiment are attached to the outer side of the bearing portion 2, which can reduce the occupation of the inner area of ​​the receiving cavity by the connecting portion 7. At the same time, the two extension sections 723 are attached to different areas of the outer side of the bearing portion 2 to avoid short circuit between the two extension sections 723.

[0158] In some embodiments, Figure 19-21 As shown, the body 4 further includes a plurality of positioning members 61, and the plurality of positioning members 61 are respectively protruded from the two side plates 6. The first connecting end 721 has a positioning hole 7211, and the positioning member 61 is clamped in the positioning hole 7211.

[0159] The positioning member 61 in this embodiment is used to fix the positioning hole 7211, so that the first connection end 721 can be fixed together with the side plate 6, thereby preventing the connection part 7 from falling off from the body 4 during the installation and use of the charging device.

[0160] In some embodiments, Figure 19-21 As shown, the positioning member 61 includes a column 611 and a plurality of flanges 612, and the plurality of flanges 612 are protruded from the side of the column 611. The column 611 extends into the positioning hole 7211 and the plurality of flanges 612 abut against the edge of the positioning hole 7211.

[0161] Specifically, multiple flanges 612 are evenly distributed around the cylinder 611, and a guide cone is provided at the end of the cylinder 611, and multiple flanges 612 are located at the bottom of the cylinder 611. A guide slope is provided on the side of the flange 612 close to the guide cone. When the positioning hole 7211 is sleeved on the positioning member 61, the guide cone can play a guiding role, and then the positioning hole 7211 will be sleeved on the multiple flanges 612 through the guide slope. At the same time, the multiple flanges 612 are interference fit with the positioning hole 7211, so that the first connection end 721 is stably connected to the side plate 6, preventing the first connection end 721 from falling off the side plate 6. The guide cone and the guide slope provided in this embodiment help the operator to press the first connection end 721 so that the multiple flanges 612 can be clamped on the inner side of the positioning hole 7211.

[0162] In some embodiments, Fig.21 As shown, the side plate 6 has a second mounting surface 63, which is a plane and has a plurality of grooves 65, and the positioning member 61 is protruded at the bottom of the groove 65. When the first connecting end 721 is attached to the second mounting surface 63, the plurality of positioning holes 7211 are arranged at intervals and are arranged opposite to the bottom of the plurality of grooves 65.

[0163] In this embodiment, the first connection end 721 extends along the plane. When the first connection end 721 is in contact with the second mounting surface 63 , the connection hole 7221 can maintain a distance from the bottom of the positioning member 61 to avoid interference between the connection hole 7221 and the connection position of the positioning member 61 and the groove 65 .

[0164] In some embodiments, Figure 5 As shown, the earphone slot 22 has an open end 221. Figure 19-20 As shown, the side plate 6 also has a first mounting surface 62 and a second mounting surface 63, and the direction of the second mounting surface 63 is opposite to the direction of the opening end 221. The first connecting end 721 is arranged on the second mounting surface 63, and a part of the contact plate 71 is arranged on the first mounting surface 62, and the edge of the contact plate 71 extends to the first connecting end 721.

[0165] In this embodiment, the first connection end 721 is located at the bottom of the side plate 6. Figure 22-Figure 23 As shown, in the process of the feeding spring piece 81 being inserted between the two contact plates 71 from the direction of the contact plate 71 away from the opening end 221, a friction force is generated between the feeding spring piece 81 and the contact plate 71, and the friction force is directed toward the direction of the opening end 221. Therefore, in this embodiment, the first connecting end 721 is arranged at the bottom of the side plate 6, and the friction force of the feeding spring piece 81 acting on the contact plate 71 can be offset by the cooperation between the first connecting end 721 and the second mounting surface 63, thereby ensuring that after the lining 261 and the basin bottom 262 are installed, the connecting part 7 and the feeding part 8 can still be stably connected.

[0166] In some embodiments, Figure 8-Figure 9 As shown, the feeding unit 9 further includes two conductive arms 1. The conductive arms 1 include an electrical contact surface 131, a fixing section 15 and a feeding end 16 in the extending direction. The fixing section 15 is located between the electrical contact surface 131 and the feeding end 16, and the fixing section 15 is fixedly connected to the body 4.

[0167] When the conductive arm 1 is in a free state, one end of the conductive arm 1 with the electrical contact surface 131 extends into the earphone slot 22 , the feeding end 16 and the second connecting end 722 are located on the side of the body 4 away from the opening end 221 , and the second connecting end 722 is electrically connected to the feeding end 16 .

[0168] Specifically, the material of the connecting portion 7 in this embodiment can be metal, such as copper, iron, copper alloy, aluminum alloy and the like. The connecting portion 7 can be made by a stamping process. Thus, the contact plate 71 and the strip conductor 72 are integrally formed. During the connection between the connecting portion 7 and the body 4, the operator turns the body 4 over so that the open end 221 faces downward. Then the connecting portion 7 is moved from the upper side of the body 4 to the body 4 so that the positioning hole 7211 is sleeved on the positioning member 61, the strip conductor 72 is attached to the outer wall of the bearing portion 2, and the connecting hole 7221 is sleeved on the feeding end 16. In this form, the feeding end 16 extends into the connecting hole 7221 and the feeding end 16 does not contact the connecting hole 7221 to avoid stress between the connecting portion 7 and the body 4 and the conductive arm 1. Finally, the second connecting end 722 is fixed to the feeding end 16 by soldering.

[0169] In some embodiments, Figure 6-Figure 9 As shown, the carrying portion 2 further has a positioning recess 23, and the positioning recess 23 is opposite to the earphone slot 22. The charging device further includes a positioning portion 24, and the fixing section 15 is disposed in the positioning recess 23 through the positioning portion 24.

[0170] Specifically, the conductive arm 1 in this embodiment further includes a first deformation zone 11 and a second deformation zone 12. The first deformation zone 11 and the second deformation zone 12 can be deformed when the earphone C is set in the earphone slot 22. In this form, the fixing zone 15 can cooperate with the positioning portion 24 to ensure that it can be stably set on the body 4 during the deformation of the first deformation zone 11 and the second deformation zone 12.

[0171] Furthermore, the positioning portion 24 is an injection molded part. The fixing section 15 is disposed in the positioning portion 24 , and the feeding end 16 extends out from the positioning portion 24 .

[0172] Specifically, the fixing section 15 includes a fourth connection section B4, and a fixing through hole 151 is formed on the fourth connection section B4, and the positioning portion 24 fills the fixing through hole 151. In this embodiment, the conductive arm 1 and the positioning portion 24 are formed by an insert molding process, and the positioning portion 24 is injection molded together with the fixing section 15 as an insert. The fixing through hole 151 can stably connect the fixing section 15 and the positioning portion 24.

[0173] In some embodiments, Figure 5-Figure 9 As shown, the side of the positioning portion 24 close to the opening end 221 is in contact with the bottom surface of the positioning recess 23, and the side away from the opening end 221 forms a glue groove 231 with the positioning recess 23, and the feeding end 16 extends from the inside of the glue groove 231 to the outside of the glue groove 231. The charging device also includes adhesive glue 5, which fills the glue groove 231.

[0174] The positioning portion 24 and the positioning recess 23 in this embodiment are positioned with each other, and the adhesive 5 is used to fix the positioning recess 23, the positioning portion 24 and the tail of the feeding terminal 16 (that is, the area of ​​the feeding terminal 16 close to the positioning portion 24). Therefore, the position accuracy is maintained during the deformation process of the conductive arm 1, especially during repeated use. Furthermore, it is ensured that the conductive arm 1 can be accurately matched with the first limiting surface 31, the second limiting surface 32 and the third limiting surface 33.

[0175] Furthermore, a connection window 232 is provided at the bottom of the positioning recess 23. The limiting groove 21 extends in a direction away from the open end 221 and is connected to the positioning recess 23 through the connection window 232. The positioning portion 24 in this embodiment can cooperate with the positioning recess 23 to ensure the installation accuracy between the conductive arm 1 and the bearing portion 2. At the same time, when the positioning portion 24 is installed in the positioning recess 23, the conductive arm 1 can extend into the limiting groove 21 through the connection window 232. Thereby, the installation method of the conductive arm 1 is simplified.

[0176] In some embodiments, Figure 19-20 As shown, the connection portion 7 also includes a plurality of solder blocks 73. The top of the cured adhesive 5 is flush with the top of the adhesive groove 231. The second connection end 722 has a connection hole 7221, and the second connection end 722 extends from the top edge of the adhesive groove 231 to the top of the adhesive 5, and the connection hole 7221 is sleeved on the feeding end 16. The second connection end 722 is fixedly connected to the adhesive 5 and the feeding end 16 through the solder block 73, and the second connection end 722 is electrically connected to the feeding end 16.

[0177] The solder block 73 in this embodiment can fix the second connection end 722 with the adhesive 5 and the feeding end 16 , and can also play a role in electrically connecting the second connection end 722 and the feeding end 16 .

[0178] The charging device in the above embodiment can be installed according to the following steps: First, the conductive arm 1 is set on the positioning portion 24 by using the insert molding process. Secondly, the bearing portion 2 is turned over so that the positioning recess 23 faces upward, the positioning portion 24 is installed in the positioning recess 23, and the conductive arm 1 is set in the limiting groove 21 and the earphone groove 22. Thirdly, the adhesive 5 is filled in the adhesive groove 231, and the feeding portion 8 is kept extending from the adhesive 5. Finally, when the adhesive 5 is cured, the assembly is completed.

[0179] Easy to understand, compared to Figure 1-Figure 2According to the structure of the charging base shown in the figure, the number of parts of the charging device in this embodiment is smaller, which reduces the manufacturing cost. At the same time, it is only necessary to fill the positioning recess 23 with adhesive 5 once, thereby improving the yield rate. On the other hand, the conductive arm 1 in this embodiment is bent so that the conductive arm 1 occupies less space and reduces the volume of the limiting groove 21. On the other hand, when the conductive arm 1 is in a free state, the free section 14 is in a suspended state. That is, the electrical contact surface 131 does not need to be positioned by the bearing portion 2, thereby further reducing the requirements for the installation accuracy of the conductive arm 1.

[0180] In some embodiments, Figure 5 , Figure 6 and Fig.15 As shown, the earphone slot 22 has two windows 222, and the number of the limiting slots 21 is two and they are connected to the earphone slot 22 through the two windows 222. The number of the conductive arms 1 is two and they extend into the earphone slot 22 through the two windows 222, and the width directions of the two conductive arms 1 are perpendicular ( Fig.25 The angle between the two dotted lines is 90 degrees).

[0181] Specifically, the charging device in this embodiment feeds direct current to the earphone C, and the two conductive arms 1 are respectively used to connect the two contacts C1 of the earphone C, and the two contacts C1 are respectively positive and negative. At the same time, the width directions of the two conductive arms 1 are perpendicular, and when the two conductive arms 1 abut against the earphone C, it can be ensured that the two conductive arms 1 stably abut the earphone C against the inner wall of the earphone slot 22.

[0182] In some embodiments, Figure 5 and Figure 17-Figure 19 As shown, the number of the positioning parts 24 , the positioning recesses 23 , the limiting grooves 21 and the conductive arms 1 are all two, and the two conductive arms 1 are simultaneously arranged corresponding to the two limiting grooves 21 , the two positioning recesses 23 and the two positioning parts 24 .

[0183] Furthermore, if Fig.18 As shown, the positioning member 61 is disposed at the bottom of the side plate 6, and the column 611, the glue groove 231 and the feeding terminal 16 are all facing the bottom of the carrying part 2. The connecting part 7 in this embodiment can be installed on the carrying part 2 from the bottom of the carrying part 2, so that the positioning hole 7211 and the connecting hole 7221 are simultaneously sleeved on the feeding terminal 16 and the positioning member 61. Thereby, the assembly of the charging device is simplified.

[0184] In some embodiments, Figure 12-Figure 15As shown, the bearing portion 2 also has two limiting grooves 21 connected to the earphone slot 22. The electrical contact surface 131 compresses the conductive arm 1 to bend and deform, and the conductive arm 1 is in contact with the inner wall of the limiting groove 21, and the conductive arm 1 drives the electrical contact surface 131 to move away from the opening end 221. The conductive arm 1 in this embodiment can cooperate with the limiting groove 21 to avoid the earphone C.

[0185] In some embodiments, Fig. 20 and Fig.24 As shown, the bearing portion 2 further includes a first shell 251 and two second shells 252. The first shell 251 has an earphone slot 22, and the earphone slot 22 has two windows 222. The two second shells 252 are integrally formed with the first shell 251 and are located on a side of the first shell 251 away from the opening end 221. The second shell 252 and the first shell 251 form a limiting groove 21 and a positioning recess 23, and the two limiting grooves 21 are connected to the earphone slot 22 through the two windows 222 respectively.

[0186] Further reference Fig.25 As shown, the two side panels 6 are protruded from the first shell 251 , and in the cross-sectional direction of the depth of the earphone slot 22 , the two side panels 6 are staggered with the two second shells 252 .

[0187] Furthermore, the two contact plates 71 are parallel to each other, and the two contact plates 71 are perpendicular to the circuit board 82. In this embodiment, the two side plates 6 are arranged on one side of the first housing 251, so that the feeding part 8 can be arranged on one side of the bearing part 2 and supply power to the conductive arm 1. Fig.25 As shown, when there are multiple bearing parts 2 , multiple side plates 6 are all arranged at positions corresponding to the circuit board 82 , which helps the feeding part 8 to use one circuit board 82 to supply power to multiple groups of contact plates 71 .

[0188] In some embodiments, Fig.24 As shown, the first shell 251 includes a first side wall 2511 and a first end wall 2512 arranged opposite to the opening end 221 . The first side wall 2511 forms an earphone slot 22 around the first end wall 2512 . A window 222 is opened at one end of the first side wall 2511 close to the first end wall 2512 .

[0189] The second housing 252 includes a second side wall 2521 and a second end wall 2522, and the thickness direction of the second end wall 2522 is consistent with the depth direction of the earphone slot 22. The second side wall 2521 extends from the second end wall 2522 along the depth direction of the earphone slot 22 to the side of the first end wall 2512 away from the opening end 221. The second side wall 2521 includes a first portion 2531 and a second portion 2532 in the extension direction, and the first portion 2531, the second end wall 2522 and the first end wall 2512 form a limiting groove 21. The inner wall of the second portion 2532 is a long waist hole, and the second portion 2532 is located on the side of the first end wall 2512 away from the opening end 221, and the second portion 2532 and a part of the first end wall 2512 form a positioning recess 23.

[0190] In this embodiment, the adhesive 5 is flush with the edge of the second portion 2532 away from the opening end 221, so that the second connection end 722 is arranged at the bottom of the body 4. At the same time, the configuration of the first shell 251 and the second shell 252 can further reduce the weight of the charging device and save the internal space of the accommodating box 26.

[0191] In some embodiments, Fig.24 As shown, the two second shells 252 are respectively arranged corresponding to the two side plates 6. Fig. 20 As shown, in the cross-sectional direction of the depth of the earphone slot 22 , the two extension sections 723 extend along the outer side surface of the first shell 251 and extend in opposite directions.

[0192] The connecting portion 7 in this embodiment can prevent the two strip conductors 72 from being short-circuited, while making maximum use of the space on the outer side of the carrying portion 2 .

[0193] In some embodiments, Fig.19 As shown, the extension section 723 includes a first section 7231 and a second section 7232. The two first sections 7231 of the two extension sections 723 are attached to the outer side surface of the first shell 251 and extend in opposite directions. The second section 7232 is attached to the outer side surface of the second side wall 2521 and extends along the depth direction of the earphone slot 22. One end of the second section 7232 extends to the edge of the second side wall 2521 away from the second end wall 2522 and is connected to the second connection end 722, and the other end is connected to one end of the first section 7231. The other end of the first section 7231 extends to the bottom of the side panel 6 and is connected to the first connection end 721.

[0194] In this embodiment, the first section 7231 and the second section 7232 are vertically connected, so that the extension section 723 can better adapt to the shape of the outer surface of the body 4. Furthermore, the structure of the extension section 723 is simplified to facilitate processing. At the same time, the length of the extension section 723 can be shortened as much as possible to reduce current loss.

[0195] In some embodiments, Fig.25 As shown, there are two bodies 4. The circuit board 82 includes four feeding areas 821, and the number of feeding springs 81 is multiple, and the multiple feeding springs 81 form two pairs of feeding springs 81, and the two pairs of feeding springs 81 are respectively arranged corresponding to the two bodies 4, and the two pairs of feeding springs 81 are arranged in four feeding areas 821.

[0196] Specifically, the charging device in this embodiment includes a accommodating box 26, two component units and a feeding part 8. The two component units are respectively used to set two earphones C, and the two component units are arranged on the lining 261. The component units include the conductive arm 1, the bearing part 2, the positioning part 24, the adhesive 5, the side panel 6 and the connecting part 7 in the above embodiment. The feeding part 8 includes a circuit board 82 and four feeding springs 81 arranged on the circuit board 82. When the operator installs the lining 261 on the basin bottom 262, the feeding springs 81 can be directly overlapped with the contact plate 71. As a result, the installation process of the charging device is greatly simplified. Avoid the flexible circuit board 263 from occupying the internal space of the accommodating box 26.

[0197] In some embodiments, Figure 3-Figure 5 As shown, the charging device in this embodiment includes a conductive arm 1 and a carrying portion 2. The carrying portion 2 has an earphone slot 22, and the earphone slot 22 has an open end 221. The ear handle portion C3 can be put into the earphone slot 22 from the open end 221.

[0198] Further reference Figure 9-10 As shown, the conductive arm 1 includes a first deformation zone 11, a second deformation zone 12 and an electrical contact section 13 in the extension direction, and the first deformation zone 11 is connected between the second deformation zone 12 and the electrical contact section 13, that is, the two ends of the first deformation zone 11 are respectively connected to the second deformation zone 12 and the electrical contact section 13. At the same time, an electrical contact surface 131 is provided at the end of the electrical contact section 13. When the earphone C is set in the earphone slot 22, the electrical contact surface 131 is used to contact with the contact C1, thereby realizing the electrical connection between the two.

[0199] At the same time, when the conductive arm 1 is in a free state, that is, the conductive arm 1 is not in contact with the earphone C, the electrical contact surface 131 is located in the earphone slot 22 and one end of the electrical contact segment 13 where the electrical contact surface 131 is arranged is inclined toward the bottom of the earphone slot 22 .

[0200] Further reference Figure 13-14 As shown, the conductive arm 1 is configured so that when the electrical contact segment 13 drives the conductive arm 1 to elastically deform, the second deformation zone 12 bends and deforms to drive the electrical contact segment 13 to move in a direction away from the earphone slot 22 .

[0201] Specifically, in this embodiment, the bottom of the earphone C applies a thrust to the electrical contact surface 131, driving the electrical contact segment 13 to move. The second deformation zone 12 is elastically bent and deformed, so that the second deformation zone 12 is shortened in the height direction of the charging device, so that the second deformation zone 12 can drive the first deformation zone 11 to move toward the bottom of the charging device, and then the electrical contact segment 13 can avoid the earphone C.

[0202] Preferably, under the push of the earphone C, part of the first deformation zone 11 also generates elastic bending deformation, so that the first deformation zone 11 can be deformed together with the second deformation zone 12, thereby increasing the deformation amplitude of the conductive arm 1.

[0203] In the above process, the end of the electrical contact segment 13 will gradually slide from the bottom surface of the ear handle portion C3 to the side surface (such as Figure 13-14 As shown, in this form, when the inclination angle of the electrical contact segment 13 is reduced to a predetermined range (for example, 53 degrees to 45 degrees), part of the first deformation interval 11 stretches and deforms, that is, the bending amplitude of part of the first deformation interval 11 is reduced, thereby driving the electrical contact surface 131 to move toward the open end 221 and finally abut against the contact C1.

[0204] Specifically, the electrical contact segment 13 in this embodiment moves from the bottom of the ear handle portion C3 to the side of the ear handle portion C3 (eg Fig.15 In this form, the second deformation zone 12 can be stretched to raise the position of the electrical contact surface 131 (as shown in the distance L1 in FIG. 1 ). Fig.16 The distance L2 in FIG. 1 is shown as the distance L2 in FIG. 1 ), so that the electrical contact surface 131 abuts against the contact point C1.

[0205] In summary, in the charging device of this embodiment, the electrical contact segment 13, the first deformation zone 11 and the second deformation zone 12 are sequentially arranged on the conductive arm 1, and the electrical contact surface 131 is arranged at the end of the electrical contact segment 13. Therefore, on the one hand, the second deformation zone 12 can drive the electrical contact segment 13 away from the earphone slot 22, so that the earphone C avoids the space in the earphone slot 22.

[0206] On the other hand, when the conductive arm 1 is not compressed, the electrical contact surface 131 is located inside the earphone slot 22, and the conductive arm 1 is tilted toward the bottom of the earphone slot 22. This helps to convert the downward pressure generated by the earphone C into a driving force acting on the electrical contact segment 13. At the same time, when the first deformation zone 11 is reduced to a predetermined range in the tilting amplitude of the electrical contact segment 13, under the continuous push of the earphone C, part of the first deformation zone 11 stretches and deforms to drive the electrical contact surface 131 to move toward the opening end 221, thereby raising the position of the electrical contact surface 131 so that the electrical contact surface 131 can abut against the contact point C1.

[0207] On the other hand, the first deformation zone 11 and the second deformation zone 12 respectively generate stretching deformation and bending deformation, which limits the elastic force applied by the conductive arm 1 to the earphone C while increasing the deformation amplitude of the conductive arm 1, thereby improving the service life of the conductive arm 1.

[0208] Optionally, the charging device in this embodiment includes a first magnetic body, and the earphone C includes a second magnetic body. When the earphone C is placed in the earphone slot 22, the first magnetic body and the second magnetic body attract each other, so that the earphone C can be stably placed on the charging device.

[0209] Further reference Fig.15 As shown, when the electrical contact segment 13 in this embodiment abuts against the contact C1, the position of the electrical contact surface 131 is raised and the inclination amplitude of the electrical contact segment 13 is reduced, thereby preventing the inclined electrical contact segment 13 from lifting the earphone C from the bottom of the ear handle C3.

[0210] In some embodiments, Figure 5-Figure 7 As shown, the bearing portion 2 further has a limiting groove 21 , which is connected to the earphone groove 22 , and the inner wall of the limiting groove 21 includes a limiting surface 3 .

[0211] Further reference Figure 9-12 As shown, the second deformation zone 12 is arranged in the limiting groove 21, and the electrical contact section 13 extends from the limiting groove 21 into the earphone groove 22. When the conductive arm 1 bends and deforms and abuts against the limiting surface 3, the electrical contact surface 131 moves from the earphone groove 22 to the limiting groove 21.

[0212] In this embodiment, when the conductive arm 1 is bent and deformed, a part of the conductive arm 1 will abut against the limiting groove 21, thereby limiting the deformation state of the conductive arm 1 and ensuring the elastic force generated by the conductive arm 1. At the same time, when the electrical contact segment 13 is away from the earphone slot 22, the limiting groove 21 can be used to accommodate the electrical contact segment 13.

[0213] In some embodiments, Figure 12-13 As shown, the limiting surface 3 includes a first limiting surface 31. The first limiting surface 31 is located on a side of the limiting groove 21 close to the earphone groove 22 and extends along the depth direction of the earphone groove 22. The second deformation interval 12 includes a first bending section A1, the first bending section A1 is bent toward the first limiting surface 31, and the second deformation interval 12 is located on a side of the first deformation interval 11 away from the opening end 221.

[0214] Specifically, the first curved section A1 is in a curved state in a free state, and its bending amplitude is an angle a1. The angle a1 may be 180 degrees.

[0215] Further reference Fig.13As shown, when the earphone C presses against the electrical contact section 13, the electrical contact section 13 transfers the downward pressure to the first bending section A1 through the first deformation zone 11, so that the first bending section A1 is bent and deformed (angle a1 is reduced). In this form, the first bending section A1 is in contact with the first limiting surface 31, and the first bending section A1 drives the first deformation zone 11 to tilt away from the earphone slot 22. In this process, the electrical contact surface 131 moves in the horizontal direction of the earphone slot 22, and the inclination of the electrical contact section 13 is reduced (angle a5 is reduced).

[0216] The first bending section A1 in this embodiment can make the first deformation interval 11 tilt as a whole to facilitate adjustment of the angle of the electrical contact section 13, and allow the first deformation interval 11 to enter the limiting groove 21 more, which helps the first deformation interval 11 to stretch and deform under the push of the earphone C.

[0217] In some embodiments, Fig.12 and Figure 13-Figure 15 As shown, the first deformation zone 11 includes a second bending section A2. In the length direction of the conductive arm 1, the second bending section A2 is located between the first bending section A1 and the electrical contact section 13, and the second bending section A2 bends in a direction away from the earphone slot 22.

[0218] When the first curved segment A1 bends and deforms and drives the second curved segment A2 to tilt away from the earphone slot 22 , the second curved segment A2 stretches and deforms (the angle a2 increases) to drive the electrical contact segment 13 closer to the opening end 221 .

[0219] In the process of the second curved section A2 of this embodiment being stretched and deformed, the earphone C continuously applies a thrust to the electrical contact section 13, and the thrust applied by the earphone C to the electrical contact section 13 is gradually changed from being directed obliquely downward to being directed horizontally. Figure 13-Figure 15 As shown, the direction of the applied thrust changes as shown by arrow b1, arrow b2 and arrow b3.

[0220] It is easy to understand that, as shown by arrows b2 and b3, the thrust applied by the earphone C can be transmitted to the fifth connecting segment B5 through the electrical contact segment 13. In this form, the earphone C can drive the fifth connecting segment B5 to open with the first connecting segment B1, so that the second curved segment A2 is stretched and deformed.

[0221] In some embodiments, Figure 7 , Fig.11 and Fig.14 As shown, the limiting surface 3 further includes a second limiting surface 32. The second limiting surface 32 is spaced apart from the first limiting surface 31 and faces the earphone slot 22. That is, the second limiting surface 32 is located on the side of the limiting slot 21 away from the earphone slot 22.

[0222] The first deformation zone 11 further includes a third curved section A3, which is located between the electrical contact section 13 and the second curved section A2 in the length direction of the conductive arm 1, and the electrical contact section 13 extends from the third curved section A3 to the earphone slot 22. The second curved section A2 stretches and deforms until the third curved section A3 abuts against the second limiting surface 32, and the first curved section A1 abuts against the first limiting surface 31.

[0223] Specifically, when the earphone C is set in the earphone slot 22, the ear handle C3 will push the third curved section A3 onto the second limiting surface 32, and the second limiting surface 32 prevents the first deformation zone 11 from moving further. In contrast, the first curved section A1 abuts against the first limiting surface 31. In this form, the horizontal shapes of the first deformation zone 11 and the second deformation zone 12 are limited by the limiting groove 21, so that the conductive arm 1 can apply sufficient elastic force to the contact C1 through the limiting groove 21, thereby maintaining a stable connection between the electrical contact surface 131 and the contact C1.

[0224] In some embodiments, Fig.12 As shown, the limiting surface 3 further includes a third limiting surface 33 . The third limiting surface 33 is opposite to the direction of the opening end 221 and is located on a side of the limiting groove 21 close to the opening end 221 . The third curved section A3 bends toward the third limiting surface 33 .

[0225] Further reference Figure 14-15 As shown, when the inclination amplitude of the electrical contact segment 13 is within a predetermined range, the first curved segment A1 and the second curved segment A2 stretch and deform to drive the third curved segment A3 to abut against the third limiting surface 33 and slide toward the second limiting surface 32 .

[0226] Specifically, the third limiting surface 33 in this embodiment is vertically connected to the second limiting surface 32. When the earphone C is in the first stroke, the first curved section A1 is in a bending deformation, and when the earphone C is in the second stroke, the first curved section A1 is stretched and deformed. Fig.13 The state shown extends to Fig.14 In this form, Fig.14 The first curved section A1 is still in a curved state, but compared with Fig.13 The bending amplitude is reduced. Thus, the first bending section A1 drives the first deformation zone 11 to approach the third limiting surface 33, so that the third bending section A3 abuts against the third limiting surface 33. Driven by the stretching deformation of the second bending section A2, the third bending section A3 slides toward the second limiting surface 32 until it abuts against the second limiting surface 32.

[0227] Therefore, the third limiting surface 33 in this embodiment can limit the lifting height of the electrical contact segment 13, and prevent the electrical contact surface 131 from lifting too much. At the same time, in the first stroke and the second stroke, the bending amplitude of the first curved segment A1 in this embodiment first increases and then decreases, so that the first curved segment A1 can buffer the fall of the earphone C and reduce the speed when the earphone C contacts the earphone slot 22.

[0228] In some embodiments, Fig.12 and Fig.15 As shown, the second limiting surface 32 extends along the depth direction of the earphone slot 22, and part of the second limiting surface 32 is arranged opposite to the first limiting surface 31. The second deformation zone 12 also includes a first connecting section B1, which is connected between the first curved section A1 and the second curved section A2.

[0229] When the first curved section A1 and the second curved section A2 are in contact with the limiting surface 3, the first connecting section B1 is located between the first limiting surface 31 and the second limiting surface 32. As a result, the elastic force generated by the conductive arm 1 is transmitted to the first limiting surface 31 and the second limiting surface 32 through the first connecting section B1, thereby limiting the deformation amplitude of the conductive arm 1 and ensuring that the electrical contact surface 131 and the contact point C1 are in stable contact. At the same time, when the first curved section A1 is bent and deformed, it can also drive the first deformation interval 11 to tilt through the first connecting section B1.

[0230] In some embodiments, Figure 8-Figure 9 As shown, the charging device also includes a positioning portion 24. Fig.12 As shown, the second deformation zone 12 further includes a second connecting segment B2, a third connecting segment B3 and a fourth curved segment A4 connected between the second connecting segment B2 and the third connecting segment B3, and the first curved segment A1 is connected between the first connecting segment B1 and the second connecting segment B2.

[0231] The third connecting section B3 extends from the fourth bending section A4 to the positioning portion 24 , and the conductive arm 1 is disposed on the supporting portion 2 through the positioning portion 24 .

[0232] Specifically, when the conductive arm 1 is in the state, the first connecting segment B1 and the second connecting segment B2 extend along the radial direction of the earphone slot 22, and the third connecting segment B3 extends along the depth direction of the earphone slot 22 (angle a4 is 90 degrees). In this embodiment, the second connecting segment B2 and the first connecting segment B1 can increase the moment when the first curved segment A1 is deformed, making the first curved segment A1 easier to deform. At the same time, the second connecting segment B2 and the third connecting segment B3 can also deform the fourth curved segment A4 to drive the first deformation interval 11 to move closer to or away from the opening end 221.

[0233] In some embodiments, Figure 12-Figure 15As shown, the first deformation zone 11 further includes a fifth connecting segment B5, the third bending segment A3 is connected between the electrical contact segment 13 and the fifth connecting segment B5, and the fifth connecting segment B5 is connected between the third bending segment A3 and the second bending segment A2.

[0234] The second curved section A2 drives the electrical contact section 13 to move through the fifth connecting section B5, and the third curved section A3 bends and deforms, driving the electrical contact section 13 to approach the fifth connecting section B5. The third curved section A3 in this embodiment can also bend and deform, thereby increasing the overall bending amplitude of the conductive arm 1.

[0235] In some embodiments, Figure 10-12 As shown, the conductive arm 1 is a strip-shaped structure. The bending direction of the conductive arm 1 is perpendicular to the width direction of the strip-shaped structure, and the widths of the first curved segment A1, the second curved segment A2, and the third curved segment A3 decrease in sequence. That is, the distance L3, the distance L4, and the distance L5 increase in sequence. The width of the fourth curved segment A4 can also be configured to be the largest, that is, the distance L6 is greater than L5.

[0236] In this embodiment, under the premise that the bending amplitudes of the various bending sections are the same, the greater the width of the bending section, the greater the stress driving the bending section to bend. In other words, the greater the width of the bending section, the greater the elastic force generated.

[0237] The widths of the first curved section A1, the second curved section A2, and the third curved section A3 are configured to decrease in sequence, and when the electrical contact section 13 drives the conductive arm 1 to deform, the first deformation zone 11 can deform quickly, so that the electrical contact section 13 is accommodated in the limiting groove 21. At the same time, after the direction of the driving force of the earphone C changes, the first curved section A1 can restore its shape in time to cooperate with the driving force of the earphone C to expand the second curved section A2.

[0238] Furthermore, the width of the fifth connecting section B5 is configured to be greater than that of the fourth connecting section B4, so that the rigidity of the region where the conductive arm 1 is connected to the positioning portion 24 is better, and the position accuracy of the first deformation zone 11 when moving is ensured.

[0239] Preferably, the first connecting segment B1, the second connecting segment B2, the electrical contact segment 13 and the fifth connecting segment B5 extend in a straight line, and the lengths of the first connecting segment B1 and the second connecting segment B2 are greater than the lengths of the electrical contact segment 13 and the fifth connecting segment B5. Thus, when the electrical contact segment 13 and the fifth connecting segment B5 approach or move away from each other, the moment generated on the third curved segment A3 is greater than the moment generated on the first curved segment A1 by the first connecting segment B1 and the second connecting segment B2. Thus, the first deformation zone 11 and the electrical contact segment 13 are more likely to deform.

[0240] In some embodiments, Fig.11 , Fig.12 and Fig.15 As shown, the electrical contact surface 131 is located at the end of the electrical contact segment 13 away from the third curved segment A3, and the electrical contact surface 131 is an arc surface.

[0241] The first deformation zone 11 further includes a free section 14, which is disposed at one end of the electrical contact section 13 away from the third curved section A3 and is bent away from the electrical contact surface 131. The conductive arm 1 is in a free state, and the electrical contact surface 131 is bent away from the second limiting surface 32.

[0242] When one end of the electrical contact segment 13 provided with the electrical contact surface 131 is raised toward the open end 221, the curved electrical contact surface 131 can face the contact point C1 to facilitate electrical connection between the two. At the same time, the free segment 14 extends away from the earphone C and sets the electrical contact surface 131 as an arc surface, which can also prevent the contact point C1 and the ear handle C3 from being scratched during the contact between the electrical contact surface 131 and the contact point C1.

[0243] In some embodiments, Fig. 9 As shown, the conductive arm 1 further includes a fixed section 15 and a feeding end 16. In the extension direction of the conductive arm 1, the second deformation section 12 is located between the first deformation section 11 and the fixed section 15, and the feeding end 16 is located at one end of the fixed section 15 away from the second deformation section 12. The charging device further includes a positioning portion 24, which is an injection molded part. The fixed section 15 is disposed in the positioning portion 24, and the feeding end 16 extends from the positioning portion 24. The feeding end 16 is used to feed current to the conductive arm 1.

[0244] In some embodiments, Fig. 9 and Fig.12 As shown, the fixed section 15 includes two fifth curved sections A5 and a fourth connecting section B4 connected between the two fifth curved sections A5. The bending directions of the two fifth curved sections A5 are opposite, the feeding end 16 is arranged at the end of one fifth curved section A5, and the second deformation section 12 extends from the other fifth curved section A5 to the limiting groove 21.

[0245] In this embodiment, the length of the fixing section 15 is increased by two fifth curved sections A5, thereby increasing the contact area between the conductive arm 1 and the positioning portion 24, so that the two are stably connected. The horizontal position of the feeding terminal 16 can also be adjusted.

[0246] In an optional implementation, the charging device in the above embodiment can be applied to an earphone assembly. The earphone assembly also includes an earphone C. The earphone C includes a contact C1. When the earphone C is set in the earphone slot 22, the contact C1 abuts against the electrical contact surface 131.

[0247] In summary, the earphone assembly in this embodiment sets the electrical contact surface 131 in the earphone slot 22, so that when the earphone C is set in the earphone slot 22, the electrical contact surface 131 can abut against the contact C1, thereby charging the earphone C. Therefore, the two contact plates 71 are respectively set on the two side panels 6, and the electrical connection position of the electrical contact surface 131 is led out to the outside of the earphone slot 22 by the connecting part 7. So that the operator can feed current into the two electrical contact surfaces 131 when installing the charging device. Furthermore, the assembly of the charging device is simplified, and the cooperation between the main body 4 and the feeding unit 9 can adapt to different forms of installation structures. Furthermore, when the two feeding springs 81 feed the two conductive arms 1, the two side panels 6 can also play a role in supporting the contact plate 71.

[0248] In another optional implementation, the charging device in the above embodiment can be applied to an earphone assembly. The earphone assembly in this embodiment also includes an earphone C. The earphone C includes a contact C1, and the earphone C compresses the conductive arm 1 through the electrical contact surface 131 to bend and deform until the earphone C is set in the earphone slot 22, and the contact C1 is in abutment with the electrical contact surface 131.

[0249] In summary, in the earphone assembly of this embodiment, the electrical contact section 13, the first deformation zone 11 and the second deformation zone 12 are sequentially arranged on the conductive arm 1, and the electrical contact surface 131 is arranged at the end of the electrical contact section 13. Therefore, on the one hand, the second deformation zone 12 can drive the electrical contact section 13 away from the earphone slot 22, so that the earphone C avoids the space in the earphone slot 22. On the other hand, when the conductive arm 1 is not compressed, the electrical contact surface 131 is located on the inner side of the earphone slot 22, and the conductive arm 1 is inclined toward the bottom of the earphone slot 22. It is helpful to convert the downward pressure generated by the earphone C into a driving force acting on the electrical contact section 13. At the same time, when the first deformation zone 11 is reduced to a predetermined range in the inclination amplitude of the electrical contact section 13, under the continuous push of the earphone C, part of the first deformation zone 11 is stretched and deformed to drive the electrical contact surface 131 to move toward the open end 221, thereby raising the position of the electrical contact surface 131 so that the electrical contact surface 131 can abut against the contact point C1. On the other hand, the first deformation zone 11 and the second deformation zone 12 respectively generate stretching deformation and bending deformation, which limits the elastic force applied by the conductive arm 1 to the earphone C while increasing the deformation amplitude of the conductive arm 1, thereby improving the service life of the conductive arm 1.

[0250] In some embodiments, Figure 11-Figure 15As shown, the earphone C also includes an earphone head C2 and an ear handle portion C3. The ear handle portion C3 is arranged on the earphone head C2 and includes a peripheral side surface C31 and a bottom side surface C32. The contact C1 is arranged on the peripheral side surface C31, the peripheral side surface C31 extends from the bottom side surface C32 to the earphone head C2, and the bottom side surface C32 is bent in a direction away from the earphone head C2. The bottom side surface C32 has a first position C41 and a second position C42, and the first position C41 is away from the earphone head C2 relative to the second position C42.

[0251] When the ear handle C3 approaches the bottom of the earphone slot 22, the electrical contact segment 13 slides from the first position C41 to the second position C42, and then slides from the second position C42 to the peripheral side surface C31. When the electrical contact segment 13 slides from the second position C42 to the peripheral side surface C31, the inclination of the electrical contact segment 13 decreases.

[0252] The diameter of the bottom of the ear handle portion C3 in this embodiment gradually increases. When the ear handle portion C3 contacts the electrical contact segment 13, the direction of the force applied by the ear handle portion C3 to the electrical contact segment 13 gradually changes, thereby raising the height of the electrical contact surface 131 through cooperation with the second curved segment A2.

[0253] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
