Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to a charging case and an earphone assembly. Background Art

[0002] The earphone charging case is an important accessory for wireless earphones. It can not only store the earphones, but also charge the earphones. The earphone charging case usually includes a conductive member and a main board. The main board is a PCB (Printed Circuit Board), and the conductive member is connected to the main board. The conductive member can be a spring pin, a copper column, etc. One end of the conductive member extends into the groove of the earphone charging case. However, there may be dimensional errors in the parts themselves and assembly errors may occur after the parts are assembled. Therefore, during the assembly process of the earphone charging case, even if the main board is correctly installed, the conductive member may not be installed at the correct angle and may not be accurately installed at the preset position, which may lead to problems such as poor contact between the earphone charging case and the earphone and easy damage of the conductive member.

[0035] Figure 1 Fig. 7 shows a headphone assembly 100 according to an embodiment of the present utility model. The headphone assembly 100 includes a charging case 200 and headphones 300. As Figure 1 shown, the charging case 200 includes a case body 202 and a cover body 201. The cover body 201 is connected to the case body 202, and the cover body 201 can rotate relative to the case body 202. The case body 202 is provided with a plurality of charging slots 204 and placement slots 203, and the charging slots 204 and the placement slots 203 are respectively used to accommodate different parts of the headphones 300.

[0036] As Figure 3 shown, the headphones 300 in this embodiment are ear-clip headphones. The headphones 300 include a charging part 301, a connecting part 302, and an earplug part 303. The connecting part 302 is arc-shaped. The two ends of the connecting part 302 are respectively connected to the charging part 301 and the earplug part 303. The connecting part 302 has elasticity so that the charging part 301 and the earplug part 303 can be opened when the user wears or removes the headphones 300. The earplug part 303 is used to be inserted into the user's ear canal. A speaker (not shown) is provided inside the earplug part 303, and the earplug part 303 can play sound. After the user wears the headphones 300 well, the connecting part 302 will bypass the outer contour of the user's ear, the charging part 301 will be located at the back of the ear, and the charging part 301 and the earplug part 303 jointly clamp the user's ear, thereby preventing the headphones 300 from falling off. The charging part 301 can be accommodated in the charging slot 204, and the earplug part 303 can be accommodated in the placement slot 203.

[0037] In Figure 1 , the charging case 200 is in an open state. When the charging case 200 is in a closed state, the cover body 201 will cover the charging slot 204 and the placement slot 203, so that the headphones 300 are completely received inside the charging case 200. It should be noted that in some other embodiments not shown in the drawings, if the headphones 300 are not configured as ear-clip headphones 300, then the case body 202 may not be provided with the placement slot 203 either.

[0038] Figure 2 is an exploded view of the charging case 200, as Figure 2 shown. The charging case 200 further includes a main board 211 and a charging board assembly 207. The case body 202 includes an installation cavity 213, and both the main board 211 and the charging board assembly 207 are disposed in the installation cavity 213. Specifically, as Figure 2 shown, the case body 202 includes a bottom shell 212 and a middle shell 206. The bottom shell 212 is provided with the above-mentioned installation cavity 213, and a part of the middle shell 206 is also located in the installation cavity 213. The bottom shell 212 and the middle shell 206 are snap-connected to each other. The main board 211 is arranged as a PCB, and the main board 211 and the middle shell 206 can be fixed by screws. The charging board assembly 207 includes a flexible circuit board 215 and a plurality of first conductive members 214 (as Figure 5 shown). The flexible circuit board 215 can be connected to the middle shell 206 and / or the bottom shell 212 by bonding. The flexible circuit board 215 is electrically connected to the main board 211. The two ends of the first conductive member 214 are a connection end and a charging end respectively. The connection end is connected to the flexible circuit board 215, and the charging end is exposed in the charging slot 204. If taking Figure 5 as an example, the connection end is the bottom end of the first conductive member 214, and the charging end is the top end of the first conductive member 214. The state where the top end (charging end) of the first conductive member 214 is exposed in the charging slot 204 can be referred to Figure 8 . As Figure 3 shown, the earphone 300 further includes a second conductive member 305, and the second conductive member 305 is connected to the charging part 301. As Figure 9 shown, when the charging part 301 is placed in the charging slot 204, the first conductive member 214 and the second conductive member 305 are in contact with each other and conduct electricity with each other, and the earphone 300 can be charged.

[0039] In the prior art, the first conductive member is usually directly fixed on the main board. However, there may be errors in the assembly between the first conductive member and the main board, resulting in deviations of the angle and / or position of the first conductive member from the preset standard. After the assembler correctly assembles the main board and the case body, the angle and position of the first conductive member are incorrect; or, the first conductive member is correctly assembled with the case body, but the angle and position of the main board are incorrect. If the main board or the first conductive member cannot be correctly installed, on the one hand, it will affect the structural stability of the charging case, and on the other hand, it is easy to have poor contact or damage to the first conductive member, thus affecting the charging stability.

[0040] For the charging case 200 of the present utility model, its first conductive member 214 is disposed on the flexible circuit board 215, and the first conductive member 214 is not directly disposed on the main board 211. Since the flexible circuit board 215 itself has flexibility, the flexible circuit board 215 can be deformed adaptively according to the positions of the first conductive member 214 and the main board 211 to adapt to errors, thereby facilitating the assembler to correctly install the main board 211 and the first conductive member 214 at the same time, reducing the risk that the conductive member and the main board 211 cannot be correctly installed in the case 202 at the same time, and further improving the charging stability and the structural stability of the charging case 200. Moreover, when there are multiple first conductive members 214 provided on the flexible circuit board 215, the flexible circuit board 215 can also be deformed adaptively according to the positions of different first conductive members 214, so as to adapt to errors and facilitate the user to correctly assemble all the first conductive members 214 at the same time.

[0041] In addition, the first conductive member 214 of the present utility model is not disposed on another PCB board either. If the first conductive member 214 is disposed on a certain PCB board, then this PCB board also needs to be electrically connected to the main board 211 through other structures (such as a flexible cable), which will increase the number of components of the charging case 200 and the complexity of assembly. Therefore, the first conductive member 214 of the present utility model is not disposed on another PCB board but directly disposed on the flexible circuit board 215, which can eliminate the flexible cable or other electrical connection structures disposed between the main board 211 and another PCB board, thereby being beneficial to improving the assembly convenience of the charging case 200.

[0042] The following will further describe other structural details of the earphone 300 and the charging case 200.

[0043] In some embodiments, in order to ensure good contact between the first conductive member 214 and the second conductive member 305, the first conductive member 214 is set as a spring pin, and the second conductive member 305 is set as a conductive post (such as a copper post). The shape of the conductive post is simple, which is convenient for machining by a lathe.

[0044] As Figure 9 shown, the second conductive member 305 includes a contact surface 306, and the contact surface 306 is exposed on the outer surface of the charging portion 301. When the charging portion 301 is disposed in the charging slot 204, the contact surface 306 abuts against the first conductive member 214 and conducts with each other, and the contact surface 306 is perpendicular to the first conductive member 214. The spring pin (the first conductive member 214) can expand and contract along its own axis. The contact surface 306 being perpendicular to the first conductive member 214 can ensure that the pressure exerted by the second conductive member 305 on the spring pin is located on the axis 226 of the spring pin, thereby reducing the risk of the spring pin being bent.

[0045] In order to reduce the processing difficulty of the conductive posts, in some embodiments, the contact surface 306 can be set as a plane. When the contact surface 306 is a plane, the fact that the contact surface 306 is perpendicular to the first conductive member 214 means that the axis 226 of the first conductive member 214 is perpendicular to the contact surface 306.

[0046] And in order to improve the aesthetics of the earphone 300, in some embodiments, the contact surface 306 can be set as a curved surface (as Figure 9 shown), and the outer surface of the charging part 301 is also set as a curved surface, and the outer surface of the charging part 301 and the contact surface 306 are smoothly transitioned. "The outer surface of the charging part 301 and the contact surface 306 are smoothly transitioned" specifically means that: the curvature at the edge of the contact surface 306 is the same as the curvature at the edge of the exposed hole 304. When the contact surface 306 is a curved surface, the fact that the contact surface 306 is perpendicular to the first conductive member 214 means that: there is a contact point on the contact surface 306, this contact point abuts against the first conductive member 214, and if a normal line of the contact surface 306 is made at the contact point, then this normal line coincides with the axis 226 of the first conductive member 214.

[0047] As Figure 8 and Figure 9 shown, in some embodiments, the first conductive member 214 is inclined. Specifically, the box body 202 and the cover body 201 are distributed in sequence along the first direction, and the direction from the connection end to the charging end is the axial direction of the first conductive member 214, and the included angle between the axial direction and the first direction is an acute angle. In this embodiment, the cover body 201 is located below the box body 202, and the first direction is the direction from bottom to top. Taking Figure 8 as an example, the connection end is the lower end of the first conductive member 214, and the charging end is the upper end of the first conductive member 214. For the first conductive member 214 at the rear side, its axial direction is generally from the lower rear to the upper front. For the first conductive member 214 at the front side, its axial direction is generally from the lower front to the upper rear. The inclined setting of the first conductive member 214 is beneficial to reducing the space occupied by the first conductive member 214 in the first direction, and is beneficial to reducing the height of the charging box 200. Moreover, when the second conductive member 305 is inclined, the first conductive member 214 is also inclined, so as to ensure that the first conductive member 214 is perpendicular to the contact surface 306, and further ensure that the first conductive member 214 is well stressed.

[0048] The charging box 200 can accommodate two earphones 300. Correspondingly, the box body 202 is provided with two charging slots 204 and two placement slots 203 (as Figure 1 shown). Each charging slot 204 is correspondingly arranged with two first conductive members 214 (as Figure 4As shown, that is, two charging terminals are provided in each charging slot 204. The two charging slots 204 are distributed in the second direction. The charging slot 204 is divided by a reference plane 227 into two sub-regions 225 distributed in the third direction. The lengths of the two sub-regions 225 in the third direction are equal. Any two of the first direction, the second direction, and the third direction are perpendicular to each other. For example, the first direction is the direction from bottom to top, the second direction is the left-right direction, and the third direction is the front-back direction. Any one charging slot 204 and the two first conductive members 214 corresponding to the charging slot 204 satisfy that the two first conductive members 214 are spaced apart in the third direction and are respectively located on different sides of the reference plane 227, and the distance between the two first conductive members 214 gradually decreases in the first direction. Wherein, the distance between the two first conductive members 214 refers to the distance between them in the third direction. In Figure 8 "The distance between the two first conductive members 214 gradually decreases in the first direction" can also be simply understood as the two first conductive members 214 gradually approach each other from bottom to top. Since the two first conductive members 214 are located on different sides of the reference plane 227, the two first conductive members 214 can contact the earphone 300 from different sides and support the earphone 300, which is beneficial to make the earphone 300 be centered and stably located in the charging slot 204 and stably contact the first conductive members 214.

[0049] In addition, the two first conductive members 214 corresponding to the same charging slot 204 can also satisfy that the included angle between the two first conductive members 214 is not greater than 150°. The included angle between the two first conductive members 214 refers to the included angle between the axes of the two first conductive members 214. Since the space between the bottom of the middle case 206 and the inner wall surface of the bottom case 212 is limited, if the included angle between the two first conductive members 214 is greater than 150°, then at least one first conductive member 214 occupies a relatively large space in the third direction (front-back direction), which will increase the difficulty of arranging the first conductive members 214 in the installation cavity 213, or it is necessary to increase the space between the middle case 206 and the bottom case 212 to accommodate the first conductive members 214, resulting in an overly large volume of the earphone 300 case. Therefore, the included angle between the first conductive members 214 not being greater than 150° facilitates accommodating the first conductive members 214 in the installation cavity 213 or helps to avoid an overly large volume of the charging case 200.

[0050] Since the first conductive member 214 is disposed on the flexible circuit board 215 in the present utility model, it is more convenient to tilt and install the first conductive member 214 in the box body 202. The reasons are briefly described below. When the first conductive member 214 is tilted, if the first conductive member 214 is integrated on the main board 211, the following problems may exist: (1) The main board 211 is usually flat and the first conductive member 214 needs to be perpendicular to the main board 211. If there are multiple first conductive members 214 with different angles, it is difficult to integrate these first conductive members 214 on the same main board 211 at the same time. (2) The space between the bottom of the middle case 206 and the front and rear side walls of the installation cavity 213 is limited, and the volume of the main board 211 is usually relatively large (because the main board 211 usually integrates more circuits and devices); even if all the first conductive members 214 have the same angle and are integrated on the same main board 211, it is difficult to place the main board 211 near the bottom of the middle case 206. The flexible circuit board 215 has flexibility, and the volume of the part for installing the first conductive member 214 (i.e., the first connection portion 216) can be set to be relatively small. The flexible circuit board 215 is suitable for installing multiple first conductive members 214 with different angles and is also suitable for being arranged near the bottom of the middle case 206, so as to facilitate tilting and installing the first conductive member 214 in the box body 202.

[0051] Figure 5 and Figure 6 show the charging board assembly 207 from different perspectives. As Figure 5 shown, the flexible circuit board 215 includes a first connection portion 216 and a second connection portion 217. The first conductive member 214 is connected to the first connection portion 216. One or more first connection portions 216 are provided. One end of the second connection portion 217 is integrally connected to one of the first connection portions 216, and the other end of the second connection portion 217 is connected to the main board 211. Wherein, a gold finger may be provided at the end of the second connection portion 217 away from the first connection portion 216, and the second connection portion 217 is connected to the main board 211 through the gold finger (not shown) to realize the conduction of the circuit of the flexible circuit board 215 and the circuit of the main board 211. Please refer to Figure 5 and Figure 6, the charging board assembly 207 further includes a reinforcing plate 223. The reinforcing plate 223 and the first connecting portion 216 are stacked and fixed to each other. For example, the reinforcing plate 223 is disposed on the lower side of the first connecting portion 216. The reinforcing plate 223 can be made of materials such as polyimide, glass epoxy resin, stainless steel, etc. The reinforcing plate 223 and the first connecting portion 216 can be fixed by bonding. The first conductive member 214 passes through the first connecting portion 216 and the reinforcing plate 223, and the first conductive member 214 is perpendicular to the first connecting portion 216 and the reinforcing plate 223. The reinforcing plate 223 can improve the strength at the first connecting portion 216, facilitate the connection between the first conductive member 214 and the first connecting portion 216, and improve the connection stability between the first conductive member 214 and the first connecting portion 216.

[0052] As Figure 8 shown, the charging case 200 further includes a battery 209, and the battery 209 is also disposed in the installation cavity 213. The battery 209 is electrically connected to the main board 211, and the battery 209 can supply power to the first conductive member 214 through the main board 211 and the flexible circuit board 215. As Figure 7 shown, the main board 211, the battery 209, and the first connecting portion 216 are stacked in sequence along the first direction (that is, the three are stacked from bottom to top in sequence), and the second connecting portion 217 bypasses the side of the battery 209 and is thus connected to the bottom surface of the main board 211. In this setting manner, the battery 209 is located between the main board 211 and the flexible circuit board 215, and the arrangement of the various components in the case body 202 is more compact, which is beneficial to reducing the volume of the charging case 200. The charging interface 229 is fixed to the bottom surface of the main board 211, and the charging interface 229 is exposed outside the bottom case 212. An external power supply is connected to the charging interface 229 through a charging cable, and the external power supply can charge the battery 209. As Figure 2 shown, in some embodiments, the charging case 200 further includes a first partition member 208 and a second partition member 210. Both the first partition member 208 and the second partition member 210 are made of insulating materials, and the insulating materials can specifically be plastics, rubbers, and the like. The first partition member 208 is disposed between the first connecting portion 216 and the battery 209 to prevent the first connecting portion 216 or the first conductive member 214 from being short-circuited with the battery 209; the second partition member 210 is disposed between the battery 209 and the main board 211 to prevent a short circuit between the battery 209 and the main board 211.

[0053] As Figure 5 shown, in order to mount the four first conductive members 214 on the flexible circuit board 215, the flexible circuit board 215 can include two first connecting portions 216, and each of the two first connecting portions 216 is connected to two first conductive members 214. As Figure 10As shown, the first connection portion 216 includes connection holes 222, and the box body 202 includes connection posts 230. Each connection post 230 passes through a connection hole 222, thereby realizing the positioning between the box body 202 and the flexible circuit board 215. After the connection post 230 passes through the connection hole 222, the upper side surface of the first connection portion 216 can be bonded to the middle case 206, so that the first connection portion 216 and the first conductive member 214 are fixed relative to the box body 202. The flexible circuit board 215 further includes a third connection portion 221. The third connection portion 221 is in a frame shape, and the two first connection portions 216 and the third connection portion 221 are integrally connected.

[0054] As Figure 5 shown, each first connection portion 216 is provided with two first conductive members 214, and only one of the first connection portions 216 is connected to the second connection portion 217; if the assembler reverses the positions of the two first connection portions 216 during the assembly process, the second connection portion 217 cannot be connected to the main board 211. Therefore, it is necessary to adopt an anti-misassembly design on the flexible circuit board 215 to prompt the assembler how to correctly judge the correct positions where the two first connection portions 216 should be installed. In some embodiments, the two first connection portions 216 are different in the number of connection holes 222. For example, one of the first connection portions 216 is provided with three connection holes 222, and the other connection portion is provided with four connection holes 222. In this way, during the assembly process, the user can judge how the two first connection portions 216 should be installed according to the number of connection holes 222.

[0055] As Figure 5 and Figure 6 shown, in some embodiments, the flexible circuit board 215 further includes a lamp mounting portion 220. The lamp mounting portion 220 and the second connection portion 217 are integrally connected to different first connection portions 216 respectively. As Figure 5 and Figure 6 shown, the lamp mounting portion 220 is in a "T" shape. The first connection portion 216 at the rear side is connected to the second connection portion 217, and the first connection portion 216 at the front side is connected to the lamp mounting portion 220. The charging board assembly 207 further includes an indicator lamp 224, and the indicator lamp 224 is connected to the end of the lamp mounting portion 220. The fixing manner between the lamp mounting portion 220 and the middle case 206 can refer to the fixing manner between the first connection portion 216 and the middle case 206, which will not be elaborated here. As Figure 11As shown, a light-transmitting hole 205 is provided on the outer surface of the bottom shell 212 of the box body 202, and the light emitted by the indicator light 224 can be emitted from the light-transmitting hole 205. The light emitted by the indicator light 224 is used to prompt the user which state the current earphone 300 box is in. In this embodiment, the indicator light 224 is an LED, and there are two indicator lights 224 provided on the lamp mounting part 220, and the colors emitted by the two indicator lights 224 are different. For example, one indicator light 224 emits red light, and the other indicator light 224 emits green light. When the power of the charging box 200 is insufficient, the light emitted from the light-transmitting hole 205 is red light; when the power of the charging box 200 is sufficient, the light emitted from the light-transmitting hole 205 is green light. In some other embodiments, the lamp mounting part may also be provided with only one indicator light 224. When charging, the indicator light 224 is on; when not charging, the indicator light 224 is off. The control logic of the indicator light 224 is not listed one by one here.

[0056] In order to enable the light emitted by the indicator light 224 to be emitted from the light-transmitting hole 205, in some embodiments, the indicator light 224 and the light-transmitting hole 205 may be directly opposite to each other. In some embodiments, as Figure 11 shown, the indicator light 224 and the light-transmitting hole 205 may also be offset from each other. Correspondingly, the charging box 200 further includes a light guide member 228. The light guide member 228 is made of a light-transmitting material. The light guide member 228 is fixed to the bottom shell 212, and a part of the light guide member 228 is disposed in the light-transmitting hole 205. The light emitted by the indicator light 224 enters the light guide member 228, and after being refracted and reflected by the light guide member 228, it is emitted from the light-transmitting hole 205. In order to reduce light leakage, a light-shielding member (not shown) may also be provided on the outer periphery of the light guide member 228.

[0057] As Figure 5 and Figure 6 shown, the flexible circuit board 215 further includes a sensor mounting part 218. The sensor mounting part 218 and the second connecting part 217 are integrally connected to different first connecting parts 216 respectively. The sensor mounting part 218 is also in a "T" shape. The charging board assembly 207 further includes a sensor 219. The sensor 219 is mounted on the sensor mounting part 218. The sensor 219 is used to detect whether the cover body 201 covers the charging slot 204. The main board 211 can control the operation mode of the charging box 200 according to whether the cover body 201 covers the charging slot 204 (for example, control whether the charging box 200 charges the earphone 300). As Figure 11As shown, the sensor 219 is arranged upward. The fixing method between the sensor mounting portion 218 and the middle case 206 can refer to the fixing method between the first connecting portion 216 and the middle case 206, which will not be elaborated here. In one embodiment, the sensor 219 is set as a Hall sensor. Correspondingly, a magnet is installed at the front end of the cover 201. When the Hall sensor detects the magnet, the main board 211 can determine that the cover 201 covers the charging slot 204. In another embodiment, the sensor 219 can also be set as a photoelectric sensor or a contact sensor. The cover 201 triggers the sensor 219 by blocking the light of the photoelectric sensor or contacting the contact sensor.

[0058] In the present utility model, the sensor 219, the indicator light 224 and the first conductive member 214 are installed on the same flexible circuit board 215, and they do not need to be installed on different flexible circuit boards 215 respectively, which is beneficial to reducing the total number of flexible circuit boards 215 and facilitating the assembly of the charging box 200.

[0059] In the description of the present utility model, the descriptions with reference to the terms "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example.
