Each technical feature in the creation of the present utility model can be combined interactively without conflicting with each other.

[0033] Refer to Figures 1 to 5 , a wireless charging device that is convenient for storage provided by an example of the present utility model includes a housing 1, a support base 2 arranged in the housing 1, a wireless charging board 3 movably arranged on the support base 2, and a driving mechanism 4 for driving the wireless charging board 3 to extend or retract from the housing 1. An opening 11 for accommodating the extension or retraction of the wireless charging board 3 is provided on one side of the housing 1. The driving mechanism 4 includes a motor 41, a gear 42 arranged on the output shaft of the motor 41, and a rack 43 engaged with the gear 42. The motor 41 is installed in the housing 1, and the rack 43 is installed on the wireless charging board 3.

[0034] Specifically, the motor 41 drives the gear 42 to rotate, the gear 42 drives the rack 43 to move, and then drives the wireless charging board 3 to extend or retract from the housing 1. Thus, it is possible to facilitate the storage of the wireless charging board 3. When the wireless charging is not in use, the wireless charging board 3 can be prevented from being exposed, avoiding damage to the wireless charging board 3.

[0035] In some preferred embodiments, a guiding groove 21 is provided on the support base 2, and a guiding strip 311 is provided at the bottom of the wireless charging board 3. The length direction of the guiding strip 311 extends along the length direction of the rack 43. The guiding groove 21 accommodates the movement of the guiding strip 311 therethrough. Thus, it is possible to guide the wireless charging board 3 and improve the stability of the wireless charging board 3 during movement.

[0036] Specifically, the number of the guiding grooves 21 and the guiding strips 311 is two each. The two guiding strips 311 are arranged in parallel and are respectively located on both sides of the bottom of the wireless charging board 3, which can prevent the wireless charging board 3 from tilting during movement and further improve the stability of the wireless charging board 3 during movement.

[0037] Further, a side plate 312 is provided on one side of the wireless charging board 3. The guiding strip 311 is perpendicular to the side plate 312. When the wireless charging board 3 retracts, the side plate 312 blocks the opening 11. Thus, it can prevent contaminants such as dust in the external environment from entering the housing 1. Furthermore, it can avoid the components in the housing 1 from being contaminated and improve the service life of the device.

[0038] Further, a stop block 22 is provided on the side of the support base 2 close to the opening 11, and a baffle 313 is provided on the side of the wireless charging board 3 away from the side plate 312. When the wireless charging board 3 extends, one side of the stop block 22 abuts against the baffle 313, which can position the wireless charging board 3 and prevent the wireless charging board 3 from detaching from the housing 1. When the wireless charging board 3 retracts, the other side of the stop block 22 abuts against the side plate 312, which can prevent the side plate 312 from falling into the interior of the housing 1.

[0039] Refer to Figure 4 and Figure 6 In some preferred embodiments, an induction component 5 is provided between the wireless charging board 3 and the support base 2. The induction component 5 is used to sense the displacement of the wireless charging board 3. Specifically, the induction component 5 includes a magnetic part 51, a PCB board 52, and two Hall switches 53. The magnetic part 51 is provided on the wireless charging board 3, the PCB board 52 is provided on the support base 2, the PCB board 52 is strip-shaped, the two Hall switches 53 are respectively connected to both ends of the PCB board 52, and the PCB board 52 is electrically connected to the motor 41.

[0040] When the wireless charging board 3 extends, the motor 41 drives the gear 42 to rotate. The gear 42 drives the rack 43 and the wireless charging board 3 to move out of the housing 1. When the magnetic part 51 on the wireless charging board 3 corresponds to the Hall switch 53 close to the opening 11, the corresponding Hall switch 53 changes the internal circuit state due to the Hall effect and controls the motor 41 to stop working through the PCB board 52. At this time, the wireless charging board 3 stops moving, so that the wireless charging board 3 extends a set length.

[0041] When the wireless charging board 3 retracts, the motor 41 drives the gear 42 to rotate in the reverse direction. The gear 42 drives the rack 43 and the wireless charging board 3 to move into the housing 1. When the magnetic part 51 on the wireless charging board 3 corresponds to the Hall switch 53 far from the opening 11, the corresponding Hall switch 53 changes the internal circuit state due to the Hall effect and controls the motor 41 to stop working through the PCB board 52. At this time, the wireless charging board 3 stops moving, so that the cover plate 32 on the wireless charging board 3 is flush with the housing 1. Thus, it can accurately control the extending and retracting lengths of the wireless charging board 3.

[0042] Further, an installation groove 23 is provided on the support base 2. The length direction of the installation groove 23 extends along the length direction of the rack 43. The PCB board 52 is installed in the installation groove 23. Thus, the PCB board 52 can be positioned, ensuring the accurate positions of the two Hall switches 53 provided on the PCB board 52. Furthermore, the accuracy of the telescopic length of the wireless charging board 3 is ensured.

The cover plate 32 and the board body 31 enclose a cavity for accommodating the coil 33. The coil 33 is installed in the cavity. Thus, it is convenient for the installation of the coil 33. Moreover, the coil 33 is placed between the cover plate 32 and the board body 31, preventing the coil 33 from being damaged.

[0044] Referring Figure 1 and Figure 2 , in some preferred embodiments, a control component 6 is further included. The control component 6 is used to control the extension or retraction of the wireless charging board 3. Specifically, the control component 6 includes a control main board 61 and a control button module 62 electrically connected to the control main board 61. The control main board 61 is electrically connected to the motor 41. The control main board 61 is installed on the support base 2. The control button module 62 is arranged on one side of the housing 1. More specifically, the control button module 62 includes an extension button and a retraction button. The user can control the extension or retraction of the wireless charging board 3 by simply pressing the extension button or the retraction button, which is simple and convenient to operate.

[0045] When the user presses the extension button, the extension button transmits a signal to the control main board 61. The control main board 61 controls the motor 41 to rotate. The motor 41 drives the gear 42 to rotate. The gear 42 drives the rack 43 and the wireless charging board 3 to move outside the housing 1, so that the wireless charging board 3 extends a certain length.

[0046] When the user presses the retraction button, the retraction button transmits a signal to the control main board 61. The control main board 61 controls the motor 41 to rotate in the reverse direction. The motor 41 drives the gear 42 to rotate in the reverse direction. The gear 42 drives the rack 43 and the wireless charging board 3 to move inside the housing 1, so that the wireless charging board 3 retracts into the housing 1.
