When the female connector 110 and the male connector 240 are connected to each other, the first housing 100 and the second housing 200 form an integrated structure, i.e. a collar of the earphone, which can be worn and used by the user. When the female connector 110 and the male connector 240 are separated from each other, the male connector 240 is further used for plugging a power supply device such as a mobile phone or a tablet computer to charge the storage battery 290 of the earphone, and the storage battery 290 may be disposed inside the second housing 200 and electrically connected to the male connector 240.

That is, the male connector 240 has a plurality of functions, one of which is to interface with the female connector 110, so that the first casing 100 and the second casing 200 form an integral structure, and power is supplied to an electrical component (e.g., the earpiece 300) on (in) the first casing 100; the other is to be inserted into a jack of other electronic equipment (i.e., the aforementioned power supply equipment) such as a mobile phone and a tablet to charge the battery 290 of the headset.

The front end surface of the first hard shell 210 is fixedly provided with a male connector 240, the second hard shell 220 is internally provided with a storage battery 290, the male connector 240 is electrically connected with the storage battery 290, and the end of the second hard shell 220 far away from the first hard shell 210 is connected with the earphone 300 through a connecting wire 400.

The first hard shell 210 and the second hard shell 220 are made of hard materials such as hard plastic (ebonite) and metal to provide sufficient mechanical strength to the housing, the first hard shell 210 is used for fixedly mounting the male connector 240, the second hard shell 220 is a main body part of the second housing 200, and has a longer size compared to the first hard shell 210, and electronic devices such as the storage battery 290 can be disposed in the second hard shell 220. The soft shell 230 is made of soft material with certain deformation capability such as soft plastic (soft rubber), for example, the soft shell 230 may be made of elastic plastic material such as thermoplastic elastomer (TPE), thermoplastic polyurethane elastomer (TPU), or silica gel.

The electronic device provided by the embodiment of the application comprises a first shell 100 provided with a female connector 110 and a second shell 200 provided with a male connector 240, wherein when the female connector 110 and the male connector 240 are mutually butted, the first shell 100 and the second shell 200 form an integrated structure, and the electronic device can be normally used; when the female connector 110 and the male connector 240 are separated from each other, the male connector 240 can be plugged into a power supply device such as a mobile phone to charge the electronic device.

The second housing 200 in the embodiment of the present application includes a first hard housing 210, a soft housing 230, and a second hard housing 220, the male connector 240 is provided on the first hard housing 210, the second hard housing 220 serves as a main body of the second housing 200, and functional elements such as a storage battery 290 are provided inside, and the soft housing 230 connects the first hard housing 210 and the second hard housing 220, and can be bent and deformed. When the male connector 240 is plugged into a power supply device such as a mobile phone to charge the storage battery 290 and the second hard shell 220 is pressed by a user carelessly, the second hard shell 220 can swing relative to the first hard shell 210, that is, the second housing 200 can deform in a self-adaptive manner, the soft shell 230 can block transmission of internal stress, and the pressing force applied to the second hard shell 220 cannot be transmitted to the first hard shell 210, so that the electrical connection between the male connector 240 and components such as a circuit board inside the device is not easily damaged, and the plug interface of the charging device is not damaged, thereby improving the use reliability of the electronic device.

As shown in fig. 1 and fig. 2, in the embodiment of the present application, the electronic device is a neck ring type earphone, the first casing 100 and the second casing 200 are butted to form a neck ring of the earphone, and two ends of the neck ring are respectively connected to an earphone 300. In other implementation manners, the electronic device may also be other devices such as a headset or a stylus, which is not limited in this application.

As shown in fig. 6, in the embodiment of the present application, the electronic device further includes a circuit board 270 and a flexible circuit board 280 located inside the second housing 200. The circuit board 270 is fixedly disposed within the second hard housing 220 and is connected to the battery 290, and the male connector 240 is connected to the circuit board 270 via the flexible circuit board 280 disposed within the soft housing 230. The battery 290 can be charged sequentially through the male connector 240, the flexible circuit board 280 and the circuit board 270, and other electronic components such as a bluetooth chip can be further arranged on the circuit board 270.

In addition, the male connector 240 may also be a lightning (lightning) interface or other types of interfaces. At this time, the female interface 110 may be a corresponding type of female, and the male interface 240 may be inserted into an electronic device (e.g., a mobile phone or a tablet) having a corresponding type of female for charging.

As shown in fig. 6, in the embodiment of the present application, the first housing 100 and the second housing 200 are both arc-shaped rod-shaped structures, the male connector 240 is disposed on an end surface of the first hard shell 210 facing away from the second hard shell 220, and correspondingly, the female connector 110 is disposed on a connecting end surface of the first housing 100.

As shown in fig. 6, the soft shell 230 covers the outer peripheries of the first hard shell 210 and the second hard shell 220. That is, the soft shell 230 is sleeved on the first hard shell 210 and the second hard shell 220, and the soft shell 230 and the second hard shell 220 are connected into a whole structure, and only the soft shell 230 exists in the middle part of the two hard shells, but no hard shell part exists, so that the connection between the first hard shell 210 and the second hard shell 220 is reliable, and the hard shells can swing relatively, and in addition, the aesthetic degree of the appearance of the product is improved.

Further, in the embodiment of the present application, the gap length between the first hard case 210 and the second hard case 220 is 3 to 20 mm. When the gap between the two hard shells is large, the soft shell 230 is made of a soft material, which is not favorable for maintaining the stiffness of the second shell 200, i.e. the second shell 200 is easy to deform and cannot be reliably maintained in the state of an ideal arc-shaped rod-shaped structure (i.e. the initial bending state); when the gap between the two hard shells is small, there is no guarantee that the first hard shell 210 and the second hard shell 220 can deflect at a sufficient angle, so that the stress blocking effect of the soft shell 230 may be limited, which is not favorable for protecting the male connector 240. For example, the gap between the first and second hard shells 210, 220 may be 4, 5, 8, or 10, 12, 15, or 18 millimeters in length, etc.

As shown in fig. 6, the electronic device provided in the embodiment of the present application further includes a hinge module 250, where the hinge module 250 is located inside the soft shell 230 and hinges the first hard shell 210 and the second hard shell 220. By providing the hinge module 250, a rigid connection between the first hard shell 210 and the second hard shell 220 can be provided, so that the second housing 200 has sufficient mechanical strength, and the flexible circuit board 280 is prevented from being damaged or the soft shell 230 is prevented from being irreversibly deformed (e.g., plastically deformed) due to an abnormal pulling operation by a user, and in addition, the hinge module 250 can better control the swinging between the first hard shell 210 and the second hard shell 220.

Fig. 7 is a schematic view of the hinge module 250 removed from the second housing 200. Fig. 8 is an exploded view of the structure shown in fig. 5. As shown in fig. 6 to 8, the hinge module 250 includes a first hinge 251, a second hinge 252, and a hinge 253. The first hinge 251 is fixedly disposed on the first hard shell 210 by screwing, riveting, bonding, or clipping, the second hinge 252 is fixedly disposed on the second hard shell 220 by screwing, riveting, bonding, or clipping, hinge holes are respectively disposed on the first hinge 251 and the second hinge 252, and the rotating shaft 253 (which may be a pin, for example) is disposed in the hinge holes, that is, the rotating shaft 253 hinges the first hinge 251 and the second hinge 252, so that the first hard shell 210 can deflect relative to the second hard shell 220.

In the embodiment of the present application, the first hard shell 210 and the second hard shell 220 are respectively provided with a screw hole 257, the first hinge member 251 is fixedly connected to the first hard shell 210 by a screw 256 cooperating with the screw hole 257, and the second hinge member 252 is fixedly connected to the second hard shell 220 by the screw hole 257 and the screw 256.

As shown in fig. 8, in order to facilitate the installation of the components inside the housing and simplify the assembly process, in the embodiment of the present application, the first hard shell 210 is formed by covering the first half-shell 211 and the second half-shell 212, and the male connector 240 is fixedly clamped between the first half-shell 211 and the second half-shell 212. Similarly, the second hard shell 220 is formed by half shell three 221 and half shell four 222 being closed, and the soft shell 230 is formed by half shell five 231 and half shell six 232 being closed. In the production process, the first half-shell 211 and the third half-shell 221 may be respectively formed by two-section molding or 3D printing, and then the fifth half-shell 231 is formed by two-shot molding or in-mold molding, the first half-shell 211, the third half-shell 221, and the fifth half-shell 231 together form an upper cover portion of the second housing 200, the second half-shell 212, the fourth half-shell 222, and the sixth half-shell 232 together form a lower cover portion of the second housing 200, and the production process of the lower cover portion is the same as the upper cover portion, which is not described herein again.

The electronic device provided by the embodiment of the present application further includes a rotation limiter disposed in the soft shell 230, and configured to limit a deflection range of the first hard shell 210 relative to the second hard shell 220, so as to prevent the flexible circuit board 280 from being damaged or the soft shell 230 from being irreversibly deformed (e.g., plastically deformed) due to excessive deflection of the second hard shell 220 relative to the first hard shell 210. For example, the angle of deflection of the first hard case 210 with respect to the second hard case 220 may be limited to 0 to 10 degrees by a rotation limiter. The rotation limiting member may be disposed on one of the first hard shell 210 and the second hard shell 220, and is configured to abut against the other one of the first hard shell 210 and the second hard shell 220, so as to limit the abutting.

As shown in fig. 7 and 9, in the embodiment of the present application, the rotation limiting member may include a limiting protrusion 255, and the limiting protrusion 255 may be a part of the rotating shaft module 250, fixedly disposed on one of the first hinge 251 and the second hinge 252, and configured to abut against the other one of the first hinge 251 and the second hinge 252 to achieve abutting limiting, so as to achieve limiting of a deflection range of the first hinge 251 relative to the second hinge 252.

As shown in fig. 7 and 9, in the embodiment of the present application, the limiting protrusions 255 may include two limiting protrusions 255 spaced apart from each other, and the two limiting protrusions 255 are used for limiting the deflection ranges in two different directions, namely clockwise and counterclockwise. The range of deflection between the first hard shell 210 and the second hard shell 220 can now be adjusted by modifying the position of at least one of the retention bumps 255.

The electronic device provided by the embodiment of the present application further includes an elastic resetting member, and the first hard shell 210 and the second hard shell 220 are connected to each other through the elastic resetting member. When the second hard shell 220 is deflected by the pressing force, the elastic restoring member can enter a force accumulation state (for example, performing a compressive force accumulation), and when the pressing force disappears, the elastic restoring member restores the second hard shell 220 to the initial position, the amount of force accumulated by the elastic restoring member is released, and the second housing 200 is restored to the initial shape (i.e., restored to the initial full state).

As a possible implementation manner, the elastic restoring member may be the soft shell 230 itself, in which case no additional elastic component is required, and the soft shell 230 has elasticity, can be deformed adaptively under a stress, and can be restored after the stress is released.

Further, at this time, the rotating shaft assembly 250 may not be provided, and the first hard shell 210 and the second hard shell 220 are connected only by the flexible soft shell 230, which is beneficial to simplifying the structure and saving the cost.

As another possible implementation manner, the elastic restoring element may be any elastic component such as a torsion spring, a coil spring, a spring sheet, or an elastic wire.

In the embodiment of the present application, the elastic restoring member is a torsion spring 254, the torsion spring 254 can be regarded as a part of the rotating shaft module 250, and the torsion spring 254 is connected between the first hinge 251 and the second hinge 252.

Fig. 9 is a comparison of the structure of fig. 5 in an initial flexed state and a stressed state. Fig. 11 is a schematic diagram of the structure shown in fig. 5 for charging the docking charging device 20. As shown in fig. 6-9 and 11, the torsion spring 254 is compressed during assembly, and the compressed elastic force pushes the second hinge 252 to one side (clockwise rotation) until the limiting protrusion 255 at the lower side of the second hinge 252 abuts against the first hinge 251, at which time the limiting protrusion 255 at the lower side performs a limiting function, and the second hard case 220 is maintained in a deflected state, so that the second housing 200 has an initial bending state as shown in fig. 9 (a). As shown in part (a) of fig. 11, since the second housing 200 has a curvature, there is a doming phenomenon when the male connector 240 of the second housing 200 is inserted into the charging device 20 for charging.

As shown in fig. 9 (b) and fig. 11 (b), when the second housing 200 is subjected to an external force (e.g., a pressure), the middle soft shell 230 deforms, the torsion spring 254 is further compressed, and the second hard shell 220 (the second hinge member 252) rotates counterclockwise until the limiting protrusion 255 on the upper side of the second hinge member 252 and the first hinge member 251 abut against each other, at which time the limiting protrusion 255 on the upper side performs a deformation limiting function, and the whole second housing 200 is in a straightened state, so as to prevent the internal functional devices from being damaged by the force.

As shown in fig. 9 and 11, when the external force applied to the second housing 200 is removed, the second hard shell 220 rotates clockwise again by the torsion spring 254 until the limit protrusion 255 and the first hinge 251 abut against each other, and then the second housing 200 returns to the original bending state, i.e., returns to the natural state.

FIG. 10 is a comparison of an initial flexed state and a stressed state of another example of the structure shown in FIG. 5. As an alternative, as shown in fig. 10, in the embodiment shown in fig. 10, the rotary shaft assembly 250 of the previous embodiment is replaced by a shaped holder 260, and the shaped holder 260 is located in the soft shell 230 and connects the first hard shell 210 and the second hard shell 220.

The fixing holder 260 can provide fixing ability, so that the second housing 200 can be maintained in an initial bending state, and a user can conveniently wear or use the second housing. In addition, the fixing holder 260 has a deformation capability, and can deform under the action of an external force, so as to ensure that the second hard shell 220 can deflect relative to the first hard shell 210. For example, the fixing holder 260 may be a structure of a wire or a metal sheet, but is not limited thereto.

As shown in part (b) of fig. 10, in a possible implementation, the fixing holder 260 has only fixing ability and no resilience, and the fixing holder 260 is deformed under the action of an external force to deflect the second hard shell 220 relative to the first hard shell 210, and when the external force disappears, the resilience of the soft shell 230 and/or a manual operation can be used to restore the second shell 200 to the original bent state (i.e., the natural state) as shown in part (a) of fig. 10. For example, the fixing holder 260 may be a wire made of a non-elastic body such as aluminum or copper.

In another possible implementation, the fixing holder 260 has both fixing ability and resilience, and the fixing holder 260 is deformed to deflect the second hard shell 220 relative to the first hard shell 210 by an external force, and when the external force disappears, the second housing 200 can be restored to the original bent state (i.e., the natural state) by the resilience of the fixing holder 260 itself and the resilience of the soft shell 230. For example, the shape-retaining member 260 may be a wire made of an elastomer such as nitinol.

As shown in fig. 10, in the embodiment of the present application, the fixing holder 260 is a wire, the soft shell 230 includes a protrusion 233 embedded between the first hard shell 210 and the second hard shell 220, the wire is wrapped in the protrusion 233, the protrusion 233 may be integrally formed with the body of the soft shell 230 by injection molding or the like, and the wire extends along the length direction of the second housing 200.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
