Detailed Implementation

[0020] To address the issue that the integrated design of existing wireless chargers affects the grip comfort during charging, this utility model proposes a novel wireless charger that improves the grip comfort by changing it to a split design.

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] Please see Figure 1 This utility model provides a wireless charger, such as a wireless charging plug or a wireless power bank. The wireless charger includes a wireless charging platform 10, a charging base 20, and a data cable 30. The wireless charging platform 10 is detachably mounted on the outside of the charging base 20, and the two are separate units. The wireless charging platform 10 and the charging base 20 are electrically connected via the data cable 30. In use, the wireless charging platform 10 can be removed from the charging base 20 and magnetically attached to the back of the electronic device. Due to its separate design, most structural components can be housed within the charging base 20, allowing the wireless charging platform 10 to be designed to be smaller and improving the grip during charging.

[0023] The charging dock 20 includes a first housing 21, within which a first accommodating cavity is formed. The electronic control module and the pull-out module 22 are disposed within the first accommodating cavity. Specifically, the first housing 21 includes a top cover 211, side plates 212, a bottom plate 213, and a partition plate 214. The top cover 211, side plates 212, and bottom plate 213 enclose the first accommodating cavity. The partition plate 214 divides the first accommodating cavity into at least two sub-cavities, such as a first mounting cavity and a second mounting cavity. This allows the pull-out module 22 and the electronic control module to be located in different cavities. By separating the electronic control module (high voltage) from the pull-out module (low voltage) 22, the electronic control module and the pull-out module 22 can be positioned close together, reducing the size of the wireless charger and ensuring a safe electrical distance. Specifically, the top cover 211, side plate 212, and bottom plate 123 form a hexahedron. Two partition plates 214 are provided, for example, two partition plates 214 are erected between the top cover 211 and the bottom plate 213, dividing the first housing 21 into three linearly arranged sub-cavities. The sub-cavity between the two partition plates 214 (i.e., the middle sub-cavity) is the first mounting cavity, and the ones located on the left and right sides of the first mounting cavity are the second and third mounting cavities. The pull-out module 22 is disposed in the first mounting cavity, and its cable outlet 221 faces the top cover 211. The electronic control module is disposed in the second mounting cavity. The pull-out module 22 can wind and store the data cable 30 in the first mounting cavity. The wireless charging station 10 is electrically connected to the electronic control module through the data cable 30 disposed in the pull-out module 22. By pulling out the wireless charging station 10, the data cable in the pull-out module 22 can be pulled out.

[0024] The wireless charging station 10 includes a second housing (not shown), within which a second accommodating cavity is formed, and a coil assembly 12 is disposed within the second accommodating cavity. The second housing includes an upper sidewall and a lower sidewall disposed opposite to each other; for example, the upper sidewall is connected to the electronic device, and the lower sidewall is connected to the charging base 20. The coil assembly 12 is disposed inside the second accommodating cavity and close to the upper sidewall of the wireless charging station 10. Data cables 30 are electrically connected to both the electronic control module and the coil assembly 12. During charging, the wireless charging station 10 is placed against the back of the electronic device. The electronic control module controls the current entering the coil assembly 12, thereby generating a changing electromagnetic field to charge the electronic device. The coil assembly 12 is close enough to the upper sidewall of the wireless charging station 10 that the electronic device can fully receive the magnetic field generated by the coil module 12, improving charging efficiency.

[0025] The first housing 21 has a receiving position on the side facing outward, and the wireless charging platform 10 is detachably disposed in the receiving position. For example, the wireless charging platform 10 can be magnetically connected to the charging base 20. Specifically, the wireless charging platform 10 is provided with a first magnetic member 14, and the receiving position of the charging base 20 is also provided with a second magnetic member 217. The first magnetic member 14 and the second magnetic member 217 are magnetically connected, so that the wireless charging platform 10 and the charging base 20 are detachably connected. Specifically, the upper cover 211 of the charging base 20 is recessed downward to form a receiving groove 215 and a mounting groove 216. The first magnetic member 14 is disposed in the second receiving cavity of the wireless charging platform 10 and is disposed near the lower side wall of the second housing. The mounting groove 216 is below the receiving groove 215 to accommodate the second magnetic member 217; the wireless charging platform 10 is accommodated in the receiving groove 215. The depth of the receiving slot 215 is less than or equal to the thickness of the wireless charging pad 10, and / or the shape and dimensions of the receiving slot 215 match the shape and dimensions of the wireless charging pad 10. The depth of the receiving slot 215 being equal to the thickness of the wireless charging pad 10, and the matching of the shape and dimensions of the receiving slot 215 with the shape and dimensions of the wireless charging pad 10, are all designed to ensure that the wireless charging pad 10 can be perfectly embedded within it, making the wireless charger more aesthetically pleasing. The depth of the receiving slot 215 may also be less than the thickness of the wireless charging pad 10, so that a portion of the wireless charging pad 10 protrudes from the outer surface of the charging base 20. This allows the wireless charging pad 10 to charge electronic devices even when connected to an external socket (mains power) while housed within the receiving slot 215. Furthermore, the protrusion of the wireless charging pad 10 from the outer surface of the charging base 20 also makes the wireless charging pad 10 easier to disassemble. The second magnetic component 217 is fixed in the mounting slot 216. When the wireless charging station 10 is stored, it can be embedded in the receiving slot 215 and fixed to the charging base 20 by the magnetic attraction of the first magnetic component 14 and the second magnetic component 217, thereby reducing the storage volume of the entire wireless charger.

[0026] The charging base 20 has a cable outlet 2111 on its upper cover 211. The data cable 30 passes through the cable outlet 2111 and can extend and retract within it. For example, the data cable 30 pulled out by the pull-out module 22 is connected to the coil assembly 12 of the wireless charging station 10 through the cable outlet 2111. Preferably, the cable outlet 2111 is directly opposite the cable outlet end 221 of the pull-out module 22, so that the cable pulled out by the pull-out module 22 extends directly from the cable outlet 2111, making it less likely to be coiled or bent inside the charging base 20. The cable outlet 2111 is used to limit the direction of the data cable 30 pulled out by the pull-out module 22 from the charging base 20, preventing the data cable 30 from coiling or bending inside the charging base 20, which could lead to damage to the data cable 30 after prolonged use.

[0027] Preferably, a third magnetic attractor 16 is provided in the second accommodating cavity of the wireless charging station 10 near the upper side wall. The third magnetic attractor 16 is located on the outer periphery of the coil assembly 12 and is located near the upper side wall of the second housing together with the coil assembly 12. The third magnetic attractor 16 and the first magnetic attractor 14 are located on opposite sides of the second accommodating cavity, so that the magnetic attraction force is stronger when the wireless charging station 10 magnetically attracts electronic devices, and the magnetic attraction force is stronger when the wireless charging station 10 magnetically attracts the charging base 20.

[0028] Preferably, taking a wireless charger as an example, the electronic control module further includes an electronic control board and a transformer module mounted on the electronic control board. The electronic control board and the transformer module are located in the second mounting cavity of the charging base 20. A rotatable plug 23 is also provided on the side plate 212 of the first housing 21. The plug 23 passes through the first housing 21 and is electrically connected to the electronic control module. The data cable 30 is connected to the electronic control board. Understandably, the plug 23 connects to the transformer module, converting AC power into DC power, and then transmitting the DC power to the coil assembly 12 via the data cable 30. When stored, the plug 23 can be embedded in the side plate 212 of the first housing 21 to reduce storage volume; when in use, it can rotate 90° to extend outwards and directly connect to the socket. The transformer module can convert the AC power on the plug 23 into the DC power required by the electronic control module. The plug 23 and the receiving position are located on different sides of the first housing 21, so that when the wireless charger is connected to the mains power, it does not interfere with the receiving position and the wireless charging platform 10. The wireless charging platform 10 can be fixed on the charging base 20 and connected to electronic devices, increasing the usage scenarios of the wireless charger.

[0029] In actual use, firstly, rotate and flip out the plug 23 and insert it into the external socket. Then, remove the wireless charging pad 10 from the charging base 20 and magnetically attach it to the back of the electronic device that needs charging via the third magnetic attachment 16. At this time, the data cable 30 of the pull-out module 22 is pulled out from the charging base 20. The transformer module converts the AC voltage on the plug 23 into DC power and transmits it to the data cable 30. The data cable then transmits the current to the coil assembly 12 of the wireless charging pad 10, generating current that is transmitted to the charging device. When storing, the pull-out module 22 winds the data cable 30 inside the pull-out module 22. At this time, the data cable 30 is housed inside the charging base 20. The wireless charging pad 10 is fixed to the charging base 20 by the magnetic attraction of the first magnetic attachment 14 and the second magnetic attachment 16. At this time, the wireless charger can also be connected to the electronic device and can also be charged.
