[0002] For TWS Bluetooth headsets, the headset and the portable charging box have become the industry's standard combination. The charging box controls two different working states of the headset when the lid is open or closed. When the charging box is opened, the charging box controls the headset to maintain the communication state; when the charging box is closed, the charging box controls the headset to maintain the sleep or charging state. The two different working states of the headset are controlled by the control circuit of the charging box, namely the Hall switch circuit.

[0003] The Hall switch circuit of the charging box includes the Hall switch module circuit and the basic hardware functional requirements of the trigger magnetic field. In addition, considering the appearance of the product, it is necessary to add a trigger magnet to cover the ugliness and avoid the problem of the magnet being directly exposed in the visible area of ​​the appearance surface, which makes the internal assembly structure of the charging box more complicated. At the same time, a test station for the Hall module needs to be added during the finished product testing, even if the testing process of the charging box is more complicated.

Compared with the structure of the control switch of the Hall switch circuit of the traditional earphone charging device, the internal assembly structure of the earphone charging device is simpler, and there is no need to increase the test station of the Hall module, which greatly simplifies the test process of the earphone charging device.

[0039] In order to better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below in conjunction with specific embodiments:

[0040] like Figures 1 to 4 As shown, an earphone charging device 10 of an embodiment includes a charging housing 100, a placement seat 200, a switch control assembly 300 and a housing cover 400. The charging housing 100 is formed with a receiving groove 102; the placement seat 200 is located in the receiving groove 102 and connected to the charging housing 100; the switch control assembly 300 includes a switch control board 310 and a spring seat 320, and the switch control board 310 is disposed in the receiving groove 102. See also Figure 5 and Figure 6The switch control board 310 is provided with a card slot 312, and a circuit trigger sheet 314 is provided on the surface of the switch control board 310; the spring plate seat 320 includes a fixed card seat 322 and a supporting deformation sheet 324 connected to each other, the fixed card seat 322 is clamped in the card slot 312 and electrically connected to the switch control board 310, and the supporting deformation sheet 324 is provided with a pressure contact abutment portion 3242 and a conductive cantilever portion 3244; the shell cover 400 is rotatably connected to the placement seat 200, and a supporting protrusion 402 is convexly provided in the shell cover 400; when the shell cover 400 is rotated to a first predetermined angle relative to the placement seat 200, the shell cover 400 The cover is arranged on the charging shell 100, so that the placement seat 200 is accommodated in the accommodation groove 102, the supporting protrusion 402 is abutted against the pressure-contact abutting portion 3242, the supporting deformation piece 324 is deformed, and the conductive cantilever portion 3244 is abutted against the circuit triggering piece 314, so that the control circuit of the charging control board is turned on; when the shell cover 400 is rotated to a second predetermined angle relative to the placement seat 200, the shell cover 400 is opened on the charging shell 100, the supporting protrusion 402 is separated from the pressure-contact abutting portion 3242, and the conductive cantilever portion 3244 leaves the circuit triggering piece 314, so that the control circuit of the charging control board is disconnected.

[0041] In the earphone charging device 10, the shell cover 400 is rotatably connected to the placement seat 200. When the shell cover 400 is rotated to a first predetermined angle relative to the placement seat 200, the shell cover 400 is covered on the charging shell 100, so that the placement seat 200 is accommodated in the accommodation groove 102, and the abutting protrusion 402 abuts against the pressure-contact abutting portion 3242, the abutting deformation sheet 324 is deformed, so that the conductive cantilever portion 3244 abuts against the circuit trigger sheet 314, so that the control circuit of the charging control board is turned on; when the shell cover 400 is relative to the placement seat When the housing 200 is rotated to the second predetermined angle, the housing cover 400 is opened on the charging housing 100, the abutting protrusion 402 is separated from the pressure-contacting abutting portion 3242, and the conductive cantilever portion 3244 leaves the circuit triggering piece 314. Even if the conductive cantilever portion 3244 does not abut against the circuit triggering piece 314, the control circuit of the charging control board is disconnected. In this way, by relatively rotating the housing cover 400 and the placement seat 200, the conductive cantilever portion 3244 and the circuit triggering piece 314 are not in abutment or in abutment state, thereby disconnecting the control circuit of the charging control board. When the conductive cantilever portion 3244 abuts against the loop trigger sheet 314, the control loop of the charging control board is turned on to form a complete closed loop, and the earphone controls the earphone to enter a dormant state so that the external mobile Bluetooth device can find the earphone and pair with the earphone; when the conductive cantilever portion 3244 does not abut against the loop trigger sheet 314, the control loop of the charging control board is disconnected, and the earphone controls the earphone to enter a communication state, so that the external mobile Bluetooth device cannot find the earphone; the earphone charging device 10 is rotatably connected to the placement seat 200 through the shell cover 400, so that the abutting protrusion 402 abuts or separates from the pressure-contact abutting portion 3242, and the conductive cantilever portion 3244 abuts or leaves the loop trigger sheet 314, thereby realizing the conduction or disconnection of the control loop of the charging control board. Compared with the structure of the control switch of the Hall switch circuit of the traditional earphone charging device 10, the internal assembly structure of the earphone charging device 10 is simpler, and there is no need to increase the test station of the Hall module, which greatly simplifies the test process of the earphone charging device 10.

[0042] It is understandable that the traditional charging box, by designing the Hall device as an inductive switch that is relatively sensitive to the magnetic field, will constrain the layout of the internal magnetic devices, such as the magnets attracted by the upper and lower covers of the charging box, the magnets attracted by the earphones and the charging box, the influence of the magnetic field generated during the operation of the wireless charging coil, the inductor and other functional circuits, making the design flexibility of the earphone charging device 10 poor. However, the earphone charging device 10 of the present application does not need to add a Hall module, and does not need to consider the influence of the magnetic field during the design, so the design flexibility of the earphone charging device 10 is better.

[0043] like Figure 4 and Figure 5As shown, in one embodiment, the charging shell 100 is also formed with a notch groove 104 connected to the receiving groove 102. Part of the shell cover 400 is located in the notch groove 104 and is rotatably connected to the placement seat 200, so as to avoid interference with the charging shell 100 during the relative rotation of the placement seat 200 and the shell cover 400, so that the rotation process of the placement seat 200 and the shell cover 400 is smoother.

[0044] like Figure 4 and Figure 5 As shown, in one embodiment, the inner wall of the notch groove 104 is provided with an avoidance inclined surface 1042, and the shell cover 400 rotates relative to the placement seat 200 at the position corresponding to the avoidance inclined surface 1042, so as to better avoid interference between the shell cover 400 and the charging shell 100 during the rotation process relative to the placement seat 200. Furthermore, the inclination angle of the avoidance inclined surface 1042 is 45°~80°, so that the space for accommodating the rotation of the shell cover 400 relative to the placement seat 200 is larger. In this embodiment, the inclination angle of the avoidance inclined surface 1042 is 60°.

[0045] like Figure 4 and Figure 5 As shown, further, part of the deformable sheet 324 abuts against the avoidance slope 1042, so that the pressed contact portion 3242 is better deformed during the abutment process by the abutting protrusion, and then the conductive cantilever portion 3244 is better abutted against the circuit trigger sheet 314 after the pressed contact portion 3242 is deformed.

[0046] like Figure 5 and Figure 6 As shown, in one embodiment, the abutting deformation piece 324 includes a fixed connection part 3246, a pressure contact abutting part 3242 and a conductive cantilever part 3244 connected in sequence, and one end of the fixed connection part 3246 away from the pressure contact abutting part 3242 is connected to the fixed card seat 322, so that the abutting deformation piece 324 is connected to the fixed card seat 322. In this embodiment, part of the fixed connection part 3246 abuts against the avoidance inclined surface 1042, so that the pressure contact abutting part 3242 is better deformed during the abutment process of the abutting protrusion. Further, the fixed connection part 3246 is bent at a first bending angle, and when the abutting protrusion abuts against the pressure contact abutting part 3242, the pressure contact abutting part 3242 is deformed. Since part of the fixed connection part 3246 abuts against the avoidance inclined surface 1042, the pressure contact abutting part 3242 is better deformed during the abutment process of the abutting protrusion. Furthermore, the first bending angle is 120° to 160°. In this embodiment, the first bending angle is 135°. Figure 7As shown, further, the avoidance inclined surface 1042 is provided with a positioning groove 1043, and the fixed connection part 3246 abuts against the positioning groove, so that the fixed connection part 3246 abuts against the avoidance inclined surface 1042 better, so that the fixed connection part 3246 has better stability and anti-swaying performance when the pressure contact abutment part 3242 is deformed. Further, the conductive cantilever part 3244 is bent, so that the conductive cantilever part 3244 has better elasticity when it abuts against the circuit trigger sheet. In this embodiment, the conductive cantilever part 3244 is U-shaped, so that the conductive cantilever part 3244 has better elasticity.

[0047] like Figure 5 and Figure 6 As shown, further, the fixed connection part 3246 includes a first bending piece 3245, a straight connection piece 3247 and a second bending piece 3248 connected in sequence, one end of the first bending piece 3245 away from the straight connection piece 3247 is connected to the fixed card seat 322, one end of the second bending piece 3248 away from the straight connection piece 3247 is connected to the pressure contact abutment part 3242, and the second bending piece 3248 abuts against the positioning groove, so that the fixed connection part 3246 has better stability and anti-swaying performance when the pressure contact abutment part 3242 is deformed, and at the same time, the fixed connection part 3246 has better elastic deformation performance. The angle between the first bending piece 3245 and the straight connection piece 3247 is a first bending angle. Furthermore, the second bending piece 3248 is an arc-shaped bending piece, so that the fixed connection part 3246 is better connected to the pressure contact abutment part 3242.

[0048] Further, the pressure-contacting abutting portion 3242 is bent at a second bending angle, and the abutting protrusion abuts against the bending portion of the pressure-contacting abutting portion 3242 when the shell cover 400 rotates to the first predetermined angle relative to the placement seat 200, so that the abutting protrusion better abuts against the pressure-contacting abutting portion 3242. Further, the second bending angle is 150° to 170°, so that the abutting protrusion better abuts against the bending portion of the pressure-contacting abutting portion 3242. When the abutting protrusion abuts against the pressure-contacting abutting portion 3242, the pressure-contacting abutting portion 3242 is deformed at the connection with the fixed connection portion 3246, so that the conductive cantilever portion 3244 better abuts against the abutting deformation sheet 324. Furthermore, the pressure-contact contact portion 3242 is provided with a contact platform (not shown), and the contact protrusion contacts one side of the contact platform to prevent the contact protrusion from slipping during the contact process between the contact protrusion and the pressure-contact contact portion 3242, so that the contact protrusion can better contact the bending part of the pressure-contact contact portion 3242. In this embodiment, the contact platform includes a first arc-shaped flange and a second arc-shaped flange connected in sequence, and the diameter of the first arc-shaped flange is smaller than the diameter of the second arc-shaped flange, so that the contact protrusion slides from the first arc-shaped flange to the position of the second arc-shaped flange during the contact process between the contact protrusion and the contact platform, so that the contact protrusion can better contact the contact platform.

[0049] like Figure 5 and Figure 6 As shown, in one embodiment, the placement seat 200 is provided with a limiting surface 220, the limiting surface 220 is provided with an exposed hole 222, the exposed hole 222 is connected to the receiving groove 102, the placement seat 200 is provided with a through hole 230 connected to the exposed hole 222, a portion of the fixed socket 322 is exposed in the exposed hole 222, a portion of the fixed connection portion 3246 abuts against the limiting surface 220, and the supporting deformation piece 324 is passed through the through hole 230, so that the supporting deformation piece 324 and the supporting protrusion 402 are better abutted, and the supporting deformation piece 324 is passed through the through hole 230, so that the supporting deformation piece 324 is accommodated in the placement seat 200, and at the same time, the structure of the earphone charging device 10 is more compact.

[0050] like Figures 4 to 6 As shown, in one embodiment, the abutting protrusion 402 is an arc-shaped protrusion, so that the abutting protrusion 402 can better abut against the pressure-contact abutting portion 3242. In this embodiment, a pivot protrusion 410 is convexly provided in the shell cover 400, and the pivot protrusion 410 is rotatably connected to the placement seat 200, so that the shell cover 400 is rotatably connected to the placement seat 200, and the abutting protrusion 402 is convexly provided on the surface of the pivot protrusion 410, so that the fixing area of ​​the abutting protrusion is larger, thereby making the abutting protrusion have better structural strength. Further, a rotating shaft 412 is provided in the pivot protrusion 410, and the two ends of the rotating shaft 412 are respectively convexly provided at the two ends of the pivot protrusion 410, and the placement seat 200 is provided with a first pivot hole and a second pivot hole, and the two ends of the rotating shaft 412 are respectively located in the first pivot hole and the second pivot hole and are rotatably connected to the placement seat 200.

[0051] like Figure 7 As shown, further, the limiting surface 220 is convexly provided with a first convex column 223 and a second convex column 224, and a limiting groove 226 is formed between the first convex column and the second convex column. The fixed connection portion 3246 is located in the limiting groove and abuts against the limiting surface 220, so that the fixed connection portion 3246 has better stability and anti-deflection when the pressing and contacting portion 3242 is deformed, so that the conductive cantilever portion 3244 can more reliably contact the circuit triggering piece 314. Further, the limiting surface 220 is convexly provided with a supporting inclined surface block, which is located between the first convex column and the second convex column, and the supporting inclined surface block abuts against the fixed connection portion 3246, so that the fixed connection portion 3246 has better stability and anti-deflection when the pressing and contacting portion 3242 is deformed.

[0052] like Figure 7As shown, in one embodiment, the switch control board 310 is fixedly connected to the placement seat 200. In one embodiment, the earphone charging device 10 further includes a locking member 500, the switch control board 310 is provided with a through hole, the placement seat 200 is provided with a threaded hole, and the locking member is respectively penetrated in the through hole and the threaded hole, so that the switch control board 310 is reliably connected to the placement seat 200, and the switch control board 310 and the placement seat 200 are detachably connected.

[0053] like Figure 5 As shown, in one embodiment, the placement seat 200 is provided with an installation fixing groove 205, and the switch control board 310 is formed with a fixing flange 313, which is located in the installation fixing groove and is snap-fitted with the placement seat 200, so that the switch control board 310 is more reliably connected to the placement seat 200.

[0054] like Figure 5 and Figure 6 As shown, further, the fixed card seat 322 is provided with a locking protrusion 3222, which is locked in the locking groove 312, so that the fixed card seat 322 and the switch control board 310 are reliably locked.

[0055] like Figures 1 to 6As shown, the present application also provides an earphone device (not shown), including an earphone charging device 10 of any of the above-mentioned embodiments. Furthermore, the earphone charging device 10 includes a charging shell 100, a placement seat 200, a switch control assembly 300 and a shell cover 400, the charging shell 100 is formed with a receiving groove 102; the placement seat 200 is located in the receiving groove 102 and is connected to the charging shell 100; the switch control assembly 300 includes a switch control board 310 and a spring seat 320, the switch control board 310 is arranged in the receiving groove 102, the switch control board 310 is provided with a card slot 312, and the surface of the switch control board 310 is provided with a circuit trigger sheet 314; the spring seat 320 includes a fixed card seat 322 and a supporting deformation sheet 324 connected to each other, the fixed card seat 322 is clamped in the card slot 312 and is electrically connected to the switch control board 310, and the supporting deformation sheet 324 is provided with a pressure contact abutment portion 3242 and a conductive cantilever portion 324. 44; the shell cover 400 is rotatably connected to the placement seat 200, and a supporting protrusion 402 is convexly provided in the shell cover 400; when the shell cover 400 is rotated to a first predetermined angle relative to the placement seat 200, the shell cover 400 is covered on the charging shell 100, so that the placement seat 200 is accommodated in the accommodation groove 102, the supporting protrusion 402 abuts against the pressure-contact abutting portion 3242, the abutting deformation piece 324 is deformed, and the conductive cantilever portion 3244 abuts against the circuit triggering piece 314, so that the control circuit of the charging control board is turned on; when the shell cover 400 is rotated to a second predetermined angle relative to the placement seat 200, the shell cover 400 is opened on the charging shell 100, the supporting protrusion 402 is separated from the pressure-contact abutting portion 3242, and the conductive cantilever portion 3244 leaves the circuit triggering piece 314, so that the control circuit of the charging control board is disconnected.

[0056] In the earphone device described above, the shell cover 400 is rotatably connected to the placement seat 200. When the shell cover 400 is rotated to a first predetermined angle relative to the placement seat 200, the shell cover 400 is covered on the charging housing 100, so that the placement seat 200 is accommodated in the accommodation groove 102, and the abutting protrusion 402 abuts against the pressure-contact abutting portion 3242, the abutting deformation sheet 324 is deformed, so that the conductive cantilever portion 3244 abuts against the circuit trigger sheet 314, so that the control circuit of the charging control board is turned on; when the shell cover 400 is relative to the placement seat 200, the charging control board 100 is turned on. When the shell cover 400 is rotated to the second predetermined angle, the shell cover 400 is opened on the charging shell 100, the abutting protrusion 402 is separated from the pressure-contact abutting portion 3242, and the conductive cantilever portion 3244 leaves the circuit triggering piece 314. Even if the conductive cantilever portion 3244 does not abut against the circuit triggering piece 314, the control circuit of the charging control board is disconnected. In this way, by relatively rotating the shell cover 400 and the placement seat 200, the conductive cantilever portion 3244 and the circuit triggering piece 314 are not in abutment or in abutment state, thereby disconnecting or disconnecting the control circuit of the charging control board. When the conductive cantilever portion 3244 abuts against the loop trigger sheet 314, the control loop of the charging control board is turned on to form a complete closed loop, and the earphone controls the earphone to enter a dormant state so that the external mobile Bluetooth device can find the earphone and pair with the earphone; when the conductive cantilever portion 3244 does not abut against the loop trigger sheet 314, the control loop of the charging control board is disconnected, and the earphone controls the earphone to enter a communication state, so that the external mobile Bluetooth device cannot find the earphone; the above-mentioned earphone charging device 10 is rotatably connected to the placement seat 200 through the shell cover 400, so that the abutting protrusion 402 abuts or separates from the pressure-contact abutting portion 3242, and the conductive cantilever portion 3244 abuts or leaves the loop trigger sheet 314, thereby realizing the conduction or disconnection of the control loop of the charging control board. Compared with the structure of the control switch of the Hall switch circuit of the traditional earphone charging device 10, the internal assembly structure of the earphone charging device 10 is simpler, and there is no need to increase the test station of the Hall module, which greatly simplifies the test process of the earphone charging device 10.

[0057] Furthermore, the earphone device also includes an earphone (not shown), the placement seat 200 is formed with an earphone storage slot 202, the earphone is located in the earphone storage slot, and the charging control board is used to wirelessly charge the earphone. Furthermore, the charging shell 100 is provided with a bare hole 105, and the charging control board is provided with a charging interface 406 corresponding to the bare hole 105, so that the earphone charging device 10 can better connect to the outside world, and thus the earphone charging device 10 can reliably charge the earphone.

[0058] Compared with the prior art, the present invention has at least the following advantages:

[0059] 1. In the earphone charging device 10, the shell cover 400 is rotatably connected to the placement seat 200. When the shell cover 400 is rotated to a first predetermined angle relative to the placement seat 200, the shell cover 400 is covered on the charging housing 100, so that the placement seat 200 is accommodated in the accommodation groove 102, and the abutting protrusion 402 abuts against the pressure-contact abutting portion 3242, the abutting deformation sheet 324 is deformed, so that the conductive cantilever portion 3244 abuts against the circuit trigger sheet 314, so that the control circuit of the charging control board is turned on; when the shell cover 400 is relative to the placement seat 2 When the shell cover 400 is rotated to the second predetermined angle, the shell cover 400 is opened on the charging shell 100, the abutting protrusion 402 is separated from the pressure-contact abutting portion 3242, and the conductive cantilever portion 3244 leaves the circuit triggering piece 314. Even if the conductive cantilever portion 3244 does not abut against the circuit triggering piece 314, the control circuit of the charging control board is disconnected; in this way, by relatively rotating the shell cover 400 and the placement seat 200, the conductive cantilever portion 3244 and the circuit triggering piece 314 are not in a state of abutment or abutment, thereby disconnecting or conducting the control circuit of the charging control board;

[0060] 2. When the conductive cantilever portion 3244 contacts the loop trigger sheet 314, the control loop of the charging control board is turned on to form a complete closed loop. At this time, the earphone controls the earphone to enter a dormant state, so that the external mobile Bluetooth device can find the earphone and pair with the earphone; when the conductive cantilever portion 3244 does not contact the loop trigger sheet 314, the control loop of the charging control board is disconnected. At this time, the earphone controls the earphone to enter a communication state, so that the external mobile Bluetooth device cannot find the earphone;

[0061] 3. The earphone charging device 10 is rotatably connected to the placement seat 200 through the shell cover 400, so that the abutting protrusion 402 abuts against or separates from the pressure-contact abutting portion 3242, and the conductive cantilever portion 3244 abuts against or leaves the circuit trigger sheet 314, thereby realizing the connection or disconnection of the control circuit of the charging control board. Compared with the control switch structure of the Hall switch circuit of the traditional earphone charging device 10, the internal assembly structure of the earphone charging device 10 is simpler, and there is no need to increase the test station of the Hall module, which greatly simplifies the test process of the earphone charging device 10.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
