Technical Field

[0001] This invention belongs to the field of wireless charging technology, and particularly relates to a wireless charging device. Background Technology

[0002] With the development of wireless charging technology, single wireless charging devices have become relatively mature. Moreover, these single wireless charging devices have multiple different charging interfaces (such as Lightning and Type-C terminals), which can charge multiple smart devices simultaneously through different charging interfaces, thus meeting different needs.

[0003] However, since wireless charging devices have multiple different charging ports, this inevitably leads to an increase in the thickness of the device and a less streamlined product appearance. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wireless charging device that addresses the technical problem that existing wireless charging devices, due to having multiple different charging interfaces, inevitably increase their thickness and result in an unsimplistic product appearance.

[0005] This invention provides a wireless charging device, including a panel, a bottom shell, and a flip cover. The panel is fastened to the bottom shell. One end of the flip cover is damped and disposed on the outer side wall of the bottom shell. The flip cover can rotate clockwise relative to the bottom shell to the lower surface of the bottom shell or counterclockwise relative to the bottom shell to form an angle with the surface of the panel. The wireless charging device further includes a lifting adjustment mechanism disposed inside the bottom shell near the flip cover for adjusting the raising and lowering of a Type-C plug. The lifting adjustment mechanism includes a gear set, a screw, a slider, and a lifting platform. The gear set is rotatably connected to the flip cover, the screw is rotatably connected to the gear set, and the screw is threadedly connected to the slider. The slider is connected to the lifting platform via two connecting rods. The lifting platform is provided with a Type-C plug, and the lifting platform is loosely fitted onto two positioning posts.

[0006] The flip cover can rotate counterclockwise or clockwise to drive the gear set to rotate, the gear set can drive the screw to rotate, the screw can drive the slider to move back and forth in a straight line, the slider can drive the connecting rod to move back and forth, and the connecting rod can drive the lifting platform to move up and down along the two positioning columns, thereby driving the Type-C plug to move up and down.

[0007] Furthermore, the gear set includes a first transmission gear, a first double gear, a second double gear, and a second transmission gear sequentially arranged on the mounting base; one end of the transmission gear shaft of the first transmission gear is rotatably connected to the flip cover, and the other end of the transmission gear shaft of the first transmission gear is disposed on the mounting base; the first transmission gear meshes with the pinion on the first double gear, the large gear on the first double gear meshes with the pinion on the second double gear, and the large gear on the second double gear meshes with the second transmission gear.

[0008] Furthermore, the slider is disposed on the mounting base and is correspondingly disposed to the second transmission gear. The slider has a through hole along its length direction. One end of the screw is inserted into the shaft hole of the second transmission gear, and the other end of the screw is threadedly connected to the through hole.

[0009] Furthermore, the screw is provided with an external thread, and the through hole is provided with an internal thread that mates with the external thread. The screw is connected to the through hole through the mate of the external thread and the internal thread.

[0010] Alternatively, the screw may have an internal thread, and the through hole may have an external thread that mates with the internal thread, thereby connecting the screw to the through hole through the mate of the internal and external threads.

[0011] Furthermore, the lifting platform includes a base plate, a connecting part, and a flange. The bottom end of the connecting part is connected to one side of the base plate, and the top end of the connecting part is connected to one side of the flange. The Type-C plug is disposed on the base plate, and the flange is provided with two positioning holes corresponding to the two positioning posts.

[0012] Furthermore, a first fixing pin is provided on each side of the flange, and a second fixing pin is provided on each side of the slider opposite to the flange. The two ends of the two connecting rods are respectively sleeved on the first fixing pin and the second fixing pin.

[0013] Furthermore, the flap damping is connected to the middle of the outer side wall of the bottom shell.

[0014] Furthermore, a rotating shaft is provided on each of the two sides of the end where the flip cover is connected to the damping connection of the bottom shell. Two grooves adapted to the rotating shafts are provided on the outer side wall of the bottom shell. The two rotating shafts are respectively assembled in the two grooves. A first mounting hole is provided on the outer side of each of the two rotating shafts. A second mounting hole is provided on the side wall of each of the two grooves and the two first mounting holes. One end of the transmission gear shaft of the first transmission gear passes through a second mounting hole and is inserted into the corresponding first mounting hole. A fixed rotating shaft pin passes through another second mounting hole and is inserted into the corresponding first mounting hole.

[0015] Furthermore, the panel is also provided with a decorative panel, the panel is provided with a first clearance hole to avoid the Type-C plug, and the decorative panel is provided with a second clearance hole corresponding to the first clearance hole.

[0016] Furthermore, the bottom of the base shell is provided with a receiving groove for accommodating the flip cover, and the top of the flip cover facing the panel is provided with an anti-slip pad along its width direction.

[0017] The wireless charging device provided in this embodiment of the invention further includes a lifting adjustment mechanism for adjusting the raising and lowering of the Type-C plug. The lifting adjustment mechanism includes a gear set, a screw, a slider, and a lifting platform. The gear set is rotatably connected to the flip cover, the screw is rotatably connected to the gear set, and the screw is threadedly connected to the slider. The slider is connected to the lifting platform via two connecting rods. Rotating the flip cover counterclockwise or clockwise can drive the gear set to rotate, which in turn drives the screw to rotate. The screw drives the slider to move back and forth linearly, which in turn drives the connecting rods to move back and forth. The connecting rods can then drive the lifting platform to move up and down along two positioning posts, thereby raising and lowering the Type-C plug. In this way, through the lifting adjustment mechanism, when the Type-C plug is needed, it can be raised out of the wireless charging device; when it is not needed, it can be hidden inside the wireless charging device. This ensures the simplicity of the appearance of the wireless charging device while minimizing its thickness. This effectively solves the technical problem that existing wireless charging devices, due to having multiple different charging interfaces, inevitably increase their thickness and result in a less simple product appearance.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] like Figures 1-7As shown in the figure, an embodiment of the present invention provides a wireless charging device, including a panel 1, a bottom shell 2, and a flip cover 3. The panel 1 is fastened to the bottom shell 2. One end of the flip cover 3 is damped and disposed on the outer side wall of the bottom shell 2. The flip cover 3 can rotate clockwise relative to the bottom shell 2 to the lower surface of the bottom shell 2 or counterclockwise relative to the bottom shell 2 to the upper surface of the bottom shell 2, forming an angle with the surface of the panel 1. The angle is greater than or equal to 90°. The wireless charging device also includes a lifting adjustment mechanism disposed inside the bottom shell 2 near the flip cover 3 for adjusting the lifting of a Type-C plug. The lifting adjustment mechanism includes a gear set 41, a screw 42, a slider 43, and a lifting platform 44. The gear set 41 is rotatably connected to the flip cover 3. The screw 42 is rotatably connected to the gear set 41. The screw 42 is threadedly connected to the slider 43. The slider 43 is connected to the lifting platform 44 through two connecting rods 45. A Type-C plug 5 is provided on the lifting platform 44, and the lifting... The lifting platform 44 is fitted onto the two positioning posts 6. The flip cover 3 can rotate counterclockwise or clockwise to drive the gear set 41 to rotate, which in turn drives the screw 42 to rotate. The screw 42 then drives the slider 43 to move back and forth linearly, which in turn drives the connecting rod 45 to move back and forth. The connecting rod 45 then drives the lifting platform 44 to move up and down along the two positioning posts 6, thereby causing the Type-C plug 5 to move up and down. Thus, through the lifting adjustment mechanism 4, when the Type-C plug 5 is needed, it can be raised from the wireless charging device to charge the smart device; when it is not needed, it can be hidden inside the wireless charging device. This ensures the simplicity of the wireless charging device's appearance and minimizes its thickness, effectively solving the technical problem that existing wireless charging devices with multiple different charging interfaces inevitably increase their thickness and result in a less streamlined appearance.

[0028] It should be noted that the Type-C terminal 5 in this embodiment is one type of charging terminal. The wireless charging device also includes another type of charging terminal, the Lightning terminal. A charging terminal conversion mechanism switches between the Lightning terminal and the Type-C terminal 5, allowing either the Lightning terminal or the Type-C terminal 5 to be mounted on the lifting platform 44. The lifting mechanism then elevates the Type-C terminal from the wireless charging device to charge different types of smart devices, meeting various needs. In this embodiment, the Type-C terminal 5 is used as an example. The Type-C terminal 5 is mounted on the lifting platform 44 and can be elevated from the wireless charging device via the lifting mechanism. However, the Lightning terminal could also be used in this embodiment, mounted on the lifting platform 44 and elevated from the wireless charging device via the lifting mechanism. This embodiment is not limited to this specific case.

[0029] It should be noted that in this embodiment, the flip cover 3 can rotate clockwise relative to the bottom shell 2 to the lower surface of the bottom shell 2 or counterclockwise relative to the top of the bottom shell 2 to form an angle with the surface of the panel 1. The angle can be greater than or equal to 90°. In this way, when the Type-C plug 5 is charging the smart device, the flip cover 3 serves to support the smart device, making it convenient to charge the smart device.

[0030] Further, if Figure 5 and Figure 6 As shown, the gear set 41 includes a first transmission gear 411, a first double gear 412, a second double gear 413, and a second transmission gear 414 sequentially arranged on the mounting base 40. One end of the transmission gear shaft 4111 of the first transmission gear 411 is rotatably connected to the flip cover 3, and the other end of the transmission gear shaft 4111 of the first transmission gear 411 is disposed on the mounting base 40. The first transmission gear 411 meshes with the pinion on the first double gear 412, the large gear on the first double gear 412 meshes with the pinion on the second double gear 413, and the large gear on the second double gear 413 meshes with the second transmission gear 414. Thus, the flip cover 3 can rotate counterclockwise or clockwise to drive the first transmission gear 411 to rotate, the first transmission gear 411 can drive the second double gear 413 to rotate, the second double gear 413 can drive the second transmission gear 414 to rotate, and the second transmission gear 414 can drive the screw 42 to rotate.

[0031] It should be noted that, in this embodiment, the two ends of the transmission gear shaft of the first double gear 412 and the two ends of the transmission gear shaft of the second double gear 413 are respectively disposed on the mounting base 40.

[0032] Furthermore, the slider 43 is disposed on the mounting base 40 and is correspondingly disposed to the second transmission gear 414. The slider 43 has a through hole 431 along its length direction. One end of the screw 42 is inserted into the shaft hole of the second transmission gear 414, and the other end of the screw 42 is threadedly connected to the through hole 431.

[0033] Specifically, the screw 42 is provided with an external thread, and the through hole 431 is provided with an internal thread that mates with the external thread. The screw 42 is connected to the through hole 431 through the engagement of the external and internal threads; or, the screw 42 is provided with an internal thread, and the through hole 431 is provided with an external thread that mates with the internal thread. The screw 42 is connected to the through hole 431 through the engagement of the internal and external threads.

[0034] Further, if Figure 7 As shown, the lifting platform 44 includes a base plate 441, a connecting part 442, and a flange 443. The bottom end of the connecting part 442 is connected to one side of the base plate 441, and the top end of the connecting part 442 is connected to one side of the flange 443. The Type-C plug 5 is disposed on the base plate 441, and the flange 443 is provided with two positioning holes 4431 corresponding to the two positioning posts 6.

[0035] Furthermore, a first fixing pin 4432 is provided on each side of the flange 443, and a second fixing pin 432 is provided on each side of the slider 43 opposite to the flange 443. The two ends of the two connecting rods 45 are respectively sleeved on the first fixing pin 4432 and the second fixing pin 432.

[0036] It should be noted that in this embodiment, the two connecting rods 45 are respectively obliquely arranged between the flange 443 and the slider 43. That is, the connecting rods 45 are gradually raised from the bottom of the slider 43 to the top of the slider 43 along the length direction of the slider 43, so that the two connecting rods 45 drive the lifting platform 44 to move up and down along the two positioning posts 6, thereby driving the Type-C plug 5 to move up and down.

[0037] Furthermore, the flap 3 is damped and connected to the middle of the outer side wall of the bottom shell 2.

[0038] Furthermore, a pivot 31 is provided on each of the two sides of the end where the flip cover 3 is connected to the bottom shell 2 in a damping manner. Two grooves 21 that are adapted to the pivot 31 are provided on the outer side wall of the bottom shell 2. The two pivots 31 are respectively assembled in the two grooves 21. The two grooves 21 can completely accommodate the pivots 31, thereby facilitating the flip cover 3 to be flipped relative to the bottom shell 2 to the lower surface of the bottom shell 2 or to the upper surface of the bottom shell 2, which serves to store the flip cover 3. Each of the two rotating shafts 31 has a first mounting hole 311 on its outer side. Each of the two grooves 21 has a second mounting hole 211 on its side wall corresponding to the two first mounting holes 311. One end of the transmission gear shaft of the first transmission gear 411 passes through a second mounting hole 211 and is inserted into the corresponding first mounting hole 311. A fixed rotating shaft pin 7 passes through another second mounting hole 211 and is inserted into the corresponding first mounting hole 311. The flip cover 3 is dampedly connected to the bottom shell 2 through the transmission gear shaft of the first transmission gear 411 and the fixed rotating shaft pin 7, and the first transmission gear 411 is rotatably connected to the flip cover 3.

[0039] Furthermore, the panel 1 is also provided with a decorative plate 8, the panel 1 is provided with a first clearance hole 11 to avoid the Type-C plug 5, and the decorative plate 8 is provided with a second clearance hole 81 corresponding to the first clearance hole 11.

[0040] Furthermore, the bottom of the bottom shell 2 is provided with a receiving groove 22 for accommodating the flip cover 3, which facilitates the storage of the flip cover 3. The top of the flip cover 3 facing the panel 1 is provided with an anti-slip pad 32 along its width direction. The anti-slip pad 32 can play an anti-slip role in preventing the smartwatch from slipping.

[0041] The specific working process of the wireless charging device provided in this embodiment of the invention is as follows:

[0042] When the Type-C plug 5 is needed, the counterclockwise rotation of the flip cover 3 drives the first transmission gear 411 to rotate. The rotation of the first transmission gear 411 sequentially drives the rotation of the first double gear 412, the second double gear 413, and the second transmission gear 414. The rotation of the second transmission gear 414 drives the rotation of the screw 42. The rotation of the screw 42 pushes the slider 43 to move linearly to the left. The linear movement of the slider 43 to the left causes the connecting rod 45 to lift the lifting platform 44 along the positioning post 6, thereby lifting the Type-C plug 5 to charge the smart device. When not in use, the Type-C plug 5 is lifted. When the Type-C plug 5 is needed, the clockwise rotation of the flip cover 3 drives the first transmission gear 411 to rotate. The rotation of the first transmission gear 411 drives the rotation of the first double gear 412, the second double gear 413, and the second transmission gear 414 in sequence. The rotation of the second transmission gear 414 drives the rotation of the screw 42. The rotation of the screw 42 pushes the slider 43 to move to the right in a straight line. The rightward linear movement of the slider 43 causes the connecting rod 45 to lower the lifting platform 44 along the positioning post 6, thereby driving the Type-C plug 5 to lower so that it can be hidden inside the wireless charging device.

[0043] The wireless charging device provided in this embodiment of the invention further includes a lifting adjustment mechanism for adjusting the raising and lowering of the Type-C plug. The lifting adjustment mechanism includes a gear set, a screw, a slider, and a lifting platform. The gear set is rotatably connected to the flip cover, the screw is rotatably connected to the gear set, and the screw is threadedly connected to the slider. The slider is connected to the lifting platform via two connecting rods. Rotating the flip cover counterclockwise or clockwise can drive the gear set to rotate, which in turn drives the screw to rotate. The screw drives the slider to move back and forth in a straight line, which in turn drives the connecting rods to move back and forth. The connecting rods can then drive the lifting platform to move up and down along two positioning posts, thereby raising and lowering the Type-C plug. In this way, through the lifting adjustment mechanism, when the Type-C plug is needed, it can be raised out of the wireless charging device; when it is not needed, it can be hidden inside the wireless charging device. This ensures the simplicity of the appearance of the wireless charging device while minimizing its thickness, effectively solving the technical problems of increased thickness and less streamlined appearance caused by multiple different charging interfaces in existing wireless charging devices.

[0044] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
