[0057] Please see Figures 1-11 This application provides a foldable three-in-one wireless charger 1, which includes a first housing 10, a second housing 20, and a third housing 30. Each of the first housing 10, the second housing 20, and the third housing 30 is provided with a charging component. The second housing 20 and the third housing 30 are rotatably connected. The three-in-one wireless charger 1 also includes a telescopic bracket assembly 15, which is rotatably connected to the second housing 20. The first housing 10 can slide along the telescopic bracket assembly 15 from a position close to the second housing 20 to a position away from the second housing 20.

[0058] The second housing 20 and the third housing 30 are rotatably connected. When it is necessary to move the three-in-one wireless charger 1, the second housing 20 and the third housing 30 can be rotated to form the following configuration: Figure 1 The folded state shown; when the second shell 20 or the third shell 30 of the 3-in-1 wireless charger 1 is needed to charge the earphones or watch, the second shell 20 and the third shell 30 can be rotated to form the folded state shown. Figure 3 The display status shown.

[0059] The connection between the second housing 20 and the third housing 30 can be a flexible connection, for example, a connection via a flexible strip; or a rigid connection, for example, a hinge connection, or something similar. Figure 9The connection shown is achieved through a connecting rod assembly 33. Specifically, a second connecting rod through hole 332 protrudes from one side of the connecting rod assembly 33, and a second rotating shaft 334 protrudes from the other side. The second connecting rod through hole 332 is rotatably connected to the second connecting part 28, and the second rotating shaft 334 is rotatably connected to the third connecting part 38.

[0060] Furthermore, the watch module holder 36 has a watch module 37 fixed on it. The watch module holder 36 is rotatably connected to the upper shell 35 of the watch module and is used to accommodate the recess and rotate the watch module 37 out of the recess. Thus, when the watch is charged using the third shell 30, the watch module holder 36 can form a stand for the watch to adapt to the user's usage scenario. When it is necessary to carry the three-in-one wireless charger 1 for movement, the watch module holder 36 and the watch module 37 can be stored in the recess for easy carrying.

[0061] The first housing 10 can slide along the telescopic bracket assembly 15 to form a sliding connection between the telescopic bracket assembly 15 and the first housing 10, and a rotatable connection is formed between the telescopic bracket assembly 15 and the second housing 20. Therefore, when it is necessary to carry the three-in-one wireless charger 1 for movement, the first housing 10 can be slid along the telescopic bracket assembly 15 to store the telescopic bracket assembly 15 inside the first housing 10, achieving the desired effect. Figure 5 The first housing 10 is shown in its retracted state relative to the telescopic bracket assembly 15. The second housing 20 is rotated relative to the telescopic bracket assembly 15, causing the first housing 10 to approach and adhere to the second housing 20, forming a configuration as shown. Figure 1 The folded state is shown; when it is necessary to use the second shell 20 or the first shell 10 of the 3-in-1 wireless charger 1 to charge the headphones or mobile phone, the first shell 10 can be slid along the telescopic bracket assembly 15 to slide the telescopic bracket assembly 15 out of the first shell 10, achieving the following... Figure 4 The telescopic support assembly 15 is shown supporting the first housing 10, and the second housing 20 is rotated relative to the telescopic support assembly 15 to form a configuration as shown. Figure 3 The stand configuration of the 3-in-1 wireless charger 1 is shown.

[0062] Among them, the sliding connection method can be a slide rail connection.

[0063] like Figures 3-8 As shown, the first housing 10 can slide along the telescopic bracket assembly 15 in a specific sliding connection manner. In a preferred embodiment, the telescopic bracket assembly 15 is provided with a first through hole 151 extending along the displacement direction of the first housing 10. The first through hole 151 has a wavy edge in the displacement direction of the first housing 10. The elastic sliding member 17 is engaged with the first through hole 151 and slides on the wavy edge of the first through hole 151.

[0064] The wavy edge on the first through hole 151 can engage the elastic slider 17, preventing the elastic slider 17 from sliding down under gravity, thus forming a shape like... Figure 4 The support structure is as follows: Furthermore, the elastic slider 17 can be slid along the wavy edge of the first through hole 151 to adjust the support height of the first housing 10 to suit the user's charging height requirements for the mobile phone.

[0065] During sliding, the elastic slider 17 can retract when it collides with the wavy protrusion, so that the first housing 10 can slide with the telescopic bracket assembly 15 under the cooperation of the first through hole 151 and the elastic slider 17; when stable, the elastic slider 17 can extend and abut against the wavy recess, so that the telescopic bracket assembly 15 can provide support for the first housing 10.

[0066] For details, please refer to Figures 5-6 The elastic slider 17 includes a first slider 171, a second slider 172, and a spring 173; the opposite sides of the first through hole 151 have wavy edges in the displacement direction of the first housing 10; the first slider 171 and the second slider 172 are respectively engaged with the opposite sides of the first through hole 151; one end of the spring 173 is connected to the first slider 171, and the other end is connected to the second slider 172. The spring 173 is in a compressed state and is used to abut the first slider 171 and the second slider 172 against the opposite sides of the first through hole 151.

[0067] During sliding, when the first slider 171 and the second slider 172 collide with the wavy protrusion, they can create pressure on the spring 173, compressing the spring 173 so that the first housing 10 can slide with the telescopic bracket assembly 15 under the cooperation of the first through hole 151 and the elastic slider 17. When stable, the spring 173 releases pressure and extends, causing the first slider 171 and the second slider 17 to abut against the wavy recess, so that the telescopic bracket assembly 15 can provide support for the first housing 10.

[0068] Preferably, the telescopic bracket pressure plate 14 is further provided with a first limiting block 141 and a second limiting block 142; the first limiting block 141 is located between the top end of the first through hole 151 and the elastic sliding member 17, and the shape of the first limiting block 141 is adapted to the shape of the top end of the first through hole 151; the second limiting block 142 is located between the bottom end of the first through hole 151 and the elastic sliding member 17, and the shape of the second limiting block 142 is adapted to the shape of the bottom end of the first through hole 151, so as to improve the stability of the telescopic bracket assembly 15 in supporting the first housing 10.

[0069] Preferably, the telescopic bracket assembly 15 abuts against the telescopic bracket pressure plate 14 and the mobile phone module bottom shell 16; the telescopic bracket pressure plate 14 is also provided with a limiting strip 143 of a certain length, the limiting strip 143 is set close to the telescopic bracket assembly 15, and the length direction of the limiting strip 143 is consistent with the displacement direction of the first shell 10, so as to limit the offset of the telescopic bracket assembly 15 and improve the stability of the first shell 10 sliding on the telescopic bracket assembly 15.

[0070] The rotatable connection between the telescopic bracket assembly 15 and the second housing 20 can be made by referring to the rotatable connection between the second housing 20 and the third housing 30. Preferably, see [reference needed]. Figures 7-8 One end of the telescopic bracket assembly 15 is provided with a first connecting part 152, and the first connecting part 152 is provided with a second through hole 152a. The rotating shaft of the rotating shaft assembly 27 is fixed to the second through hole 152a and is rotatably connected to the telescopic bracket assembly 15.

[0071] When wirelessly charging a mobile phone through the first housing 10, the charging coil 13 on the first housing 10 can be controlled by the first PCB (Printed Circuit Board) 23 disposed inside the second housing 20. The first trace 41 between the first PCB 23 and the charging coil 13 needs to be disposed at one end inside the first housing 10 and electrically connected to the charging coil 13, and disposed at the other end inside the second housing 20 and electrically connected to the first PCB 23.

[0072] When arranging the first wiring 41 in the three-in-one wireless charger 1, preferably, the earphone charging shell 22 is provided with a third through hole 221, the third through hole 221 is aligned with the shaft of the rotating shaft assembly 27, the inner side of the telescopic bracket assembly 15 is rotatably connected to the rotating shaft assembly 27, the outer side of the telescopic bracket assembly 15 is provided with a wiring groove 153, the wiring groove 153 extends into the interior of the first shell 10, and the third through hole 221 connects to the wiring groove 153; one end of the first wiring 41 is connected to the first PCB board 23, the first wiring 41 passes through the third through hole 221 out of the first PCB board 23, extends along the wiring groove 153 into the interior of the first shell 10, and connects to the charging coil 13.

[0073] For a clearer illustration of the layout of the first wiring 41, please refer to [reference needed]. Figure 7 , Figure 7 The dotted lines in the diagram represent the distribution of the first trace 41 within the three-in-one wireless charger 1.

[0074] Furthermore, a cable baffle adapted to the wiring groove 153 can be provided on the telescopic bracket assembly 15 to prevent the first wiring 41 from being exposed.

[0075] When using the first PCB board 23 and the second PCB board 32, the power source for the first PCB board 23 and the second PCB board 32 can be a high-capacity battery, a rechargeable storage battery, or external AC power. The power for the storage battery can be supplied via external AC power.

[0076] When considering connecting external AC power to supply power to the first PCB board 23 and the second PCB board 32, an AC power interface can be provided on the third housing 30 to connect external AC power to the second PCB board 32. Then, based on the electrical connection between the first PCB board 23 and the second PCB board 32, the power from the external AC power can also be transmitted from the second PCB board 32 to the first PCB board 23 to supply power to the first PCB board 23 and the second PCB board 32 through an AC power interface.

[0077] When considering the second trace 42 for the electrical connection between the first PCB board 23 and the second PCB board 32, please refer to... Figure 9 ,in, Figure 9 The dotted lines clearly indicate the arrangement of the second wiring 42 within the three-in-one wireless charger 1. Specifically, the linkage assembly 33 has a first linkage through hole 331 and a second linkage through hole 332. The first linkage through hole 331 is located on the side of the linkage assembly 33 where the second linkage through hole 332 is located, and the second linkage through hole 332 is located on the side of the linkage assembly 33 where the second rotating shaft 334 is located. The first linkage through hole 331 and the second linkage through hole 332 are connected inside the linkage assembly 33. The side of the linkage assembly 33 where the second linkage through hole 332 is located accommodates the second linkage through hole 334. The first connecting rod through hole 331 of the connecting part 28 connects to the interior of the second housing 20; the side of the connecting rod assembly 33 with the second rotating shaft 334 is accommodated in the third connecting part 38, and the second connecting rod through hole 332 connects to the interior of the third housing 30; one end of the second wiring 42 is connected to the second PCB board 32, extends from the interior of the third housing 30 to the second connecting rod through hole 332, passes through the interior of the connecting rod assembly 33 and extends to the second connecting rod through hole 332, and extends from the interior of the second connecting rod through hole 332 to the interior of the second housing 20, and is electrically connected to the first PCB board 23.

[0078] In this embodiment, based on the rotatable connection between the second housing 20 and the third housing 30, a telescopic bracket assembly 15 is provided that is rotatably connected to the second housing 20, and the first housing 10 can slide along the telescopic bracket assembly 15, from a position close to the second housing 20 to a position away from the second housing 20, so that the three-in-one wireless charger 1 can be used in actual situations as follows:

[0079] If it is necessary to carry the 3-in-1 wireless charger 1 for mobile use, the first housing 10 can be slid along the telescopic bracket assembly 15 to be close to the second housing 20, so that the telescopic bracket assembly 15 can be accommodated through the first housing 10. Then, the first housing 10 and the third housing 30 can be rotated onto the second housing 20 respectively, forming as shown in the figure. Figure 1 The folded state shown allows the three-in-one wireless charger to be folded for easy carrying by the user;

[0080] If you need to use the first housing 10 of the 3-in-1 wireless charger 1 to charge your phone, you can first rotate the telescopic bracket assembly 15 to flip the first housing 10 off the second housing 20, and then slide the first housing 10 along the telescopic bracket assembly 15 away from the second housing 20. This allows the second housing 20 to serve as a support base, the first housing 10 to serve as a connecting part for the phone, and the telescopic bracket assembly 15 to serve as a support rod connecting the support base and the connecting part, thus forming a support structure for the phone.
