The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.
[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0026] like Figure 1-3As shown, a charging device includes a base plate 1, a wireless charging module 6, a circuit board 7, and a fan 8. The base plate 1 has at least two mounting holes 21 penetrating its inner and outer side walls. A ventilation groove 22 is formed on the edge of the inner side wall of the base plate 1. At least one end of the base plate 1 has a notch 23 communicating with the ventilation groove 22. The wireless charging module 6 is laid on the inner side wall of the base plate 1. The fan 8 and the circuit board 7 are both arranged adjacent to the wireless charging module 6 and are electrically connected to the circuit board 7. In use, the base plate 1 can be placed over an opening in a wall or table, and then the wires pre-installed at the opening can be electrically connected to the circuit board 7 so that the circuit board 7 converts the mains power into low-voltage power for the wireless charging module 6. Finally, the base plate 1 is fixed to the wall or table using screws inserted through the mounting holes 21. The base plate 1 and the inner wall of the opening in the wall or table form a mounting cavity, allowing air to pass through. Through ventilation slots 22 and notches 23, air can be exchanged with the outside. Mobile devices can be magnetically attached to the outer wall of the base plate 1 and wirelessly charged using the wireless charging module 6. This allows the charging device to be directly fixed on the furniture surface or the opening reserved for switch or socket panels on the wall during the decoration stage, avoiding the safety hazards caused by exposed charging device wiring. At the same time, it takes into account both charging function and spatial aesthetics, to meet the needs of modern residences for concealed and integrated charging facilities, and to achieve seamless integration of infrastructure and smart devices. When the inner wall of the base plate 1 is in contact with the wall or tabletop, outside air can still be exchanged with the air in the installation cavity through ventilation slots 22 and notches 23. During the charging process, the circuit board 7 will activate the fan 8 to disturb the airflow in the installation cavity, accelerate the exchange of hot air in the installation cavity with outside cold air, help the circuit board 7 and the wireless charging module 6 dissipate heat, improve the heat dissipation efficiency of both, and extend their service life.
[0027] Specifically, the opening in the wall or tabletop can be the opening of a dark box; the base plate 1 can be any rectangle or circle, and in this embodiment, it is preferably square to fit the common outline of a dark box.
[0028] Furthermore, the ventilation slot 22 is annular and is set along the periphery of the base plate 1. There are two notches 23, which are symmetrically distributed at the upper and lower ends of the base plate 1. Taking the installation position as a wall as an example, when the base plate 1 is fixed to the wall, the wall will cover the notches 23 and the outer periphery of the opening of the ventilation slot 22. However, the outside air can still flow into the ventilation slot 22 through the two notches 23 and diffuse through the ventilation slot 22. It flows into the installation cavity from the inner periphery of the uncovered opening of the ventilation slot 22, so as to improve the ventilation efficiency between the installation cavity and the outside, and facilitate the cooling of the wireless charging module 6 and the circuit board 7.
[0029] Furthermore, the base plate 1 includes an annular outer plate 2 and an inner plate 3 fixed to the front side wall of the outer plate 2 by screws. Mounting holes 21 are distributed around the periphery of the outer plate 2. The inner plate 3 covers the inner opening of the outer plate 2. The wireless charging module 6, the circuit board 7 and the fan 8 are all fixedly installed on the inner side wall of the inner plate 3. The base plate 1 is divided into two parts, which makes it easier to reduce the processing difficulty of the base plate 1 and improve economic efficiency.
[0030] Furthermore, the middle part of the inner plate 3 protrudes outward to form a hollow protrusion 31. The wireless charging module 6 is laid on the axial inner end wall of the protrusion 31 so that users can identify the wireless charging area through the protrusion 31, reducing the difficulty of operation and the learning cost.
[0031] Furthermore, the charging device also includes an annular magnet 9. The annular first protrusion 32 is coaxially provided in the middle of the axial inner end wall of the protrusion 31. The magnet 9 is sleeved on the outside of the first protrusion 32, and the wireless charging module 6 is sleeved on the inside of the first protrusion 32, so that the wireless charging module 6 is located inside the axial projection of the magnet 9, avoiding excessive interference of the magnetic field of the magnet 9 itself with the signal transmission of the wireless charging module 6, and ensuring charging efficiency. The annular magnet can be adapted to the adsorption of most mobile devices on the market. The mobile device can be adsorbed on the outer wall of the protrusion 31 for wireless charging, so that the charging device can be installed on the wall for use.
[0032] Furthermore, several support bars 33 are vertically arranged on the axial inner end wall of the protrusion 31. The support bars 33 are distributed circumferentially along the protrusion 31. Several socket holes 81 are distributed circumferentially on the fan 8, penetrating its front and rear side walls. The fan 8 is located inside the wireless charging module 6. The support bars 33 are correspondingly fitted into the socket holes 81. The circuit board 7 is fixedly installed inside the fan 8 so as to provide positioning and support for the fan 8 through the support bars 33, reducing the installation difficulty of the fan 8. The fan 8 can be locked onto the support bars 33 by screws coaxially screwed to the end of the support bars 33 (not shown in the figure), or the support bars 33 can be connected to the inner wall of the socket holes 81 by adhesive to help fix the fan 8.
[0033] Furthermore, the charging device also includes a rear cover 4, which is fixedly fitted inside the outer plate 2 and encloses the wireless charging module 6, fan 8, and circuit board 7. The wireless charging module 6, fan 8, and circuit board 7 are arranged sequentially along the inner plate 3 to the rear cover 4. The inner sidewall of the circuit board 7 is integrated with a wiring terminal 71. The rear cover 4 has a heat dissipation vent 41 and a wiring port 42 for the wiring terminal 71 to run to the outside. The rear cover 4 can protect the wireless charging module 6, fan 8, and circuit board 7 from being bumped by external objects. External wires can be connected to the wiring terminal 71 through the wiring port 42 to supply power to the circuit board 7.
[0034] Furthermore, a second protruding edge 34 is provided on the inner sidewall of the inner plate 3 along its periphery. The outline of the second protruding edge 34 matches the opening end of the rear cover 4. Several locking positions 35 are distributed circumferentially on the inner side of the second protruding edge 34. Several hooks 43 are correspondingly distributed on the opening end of the rear cover 4. The opening end of the rear cover 4 is inserted into the inner side of the second protruding edge 34 through the inner opening of the outer plate 2, so that the hooks 43 and locking positions 35 are engaged one by one, so that the rear cover 4 and the inner plate 3 can be quickly connected. The operator can press the root of the hook 43 to drive the hook 43 to swing away from the corresponding locking position 35, so as to remove the rear cover 4 for inspection of the wireless charging module 6, fan 8 and circuit board 7.
[0035] Furthermore, a number of connecting posts 44 are vertically provided on the axial inner end wall of the rear cover 4. The connecting posts 44 are evenly distributed along the circumference of the rear cover 4. A number of connecting holes 72 are distributed along the circumference of the circuit board 7, penetrating the front and rear side walls. The inner side wall of the circuit board 7 abuts against the ends of the connecting posts 44. The circuit board 7 is fixed to the connecting posts 44 one by one by screws inserted in the connecting holes 72, so as to fix the circuit board 7 inside the rear cover 4.
[0036] Furthermore, the charging device also includes a face cover 5, which is fixedly covered to the outer side wall of the outer plate 2. The face cover 5 has a relief opening 51 in the middle, and the protrusion 31 passes through the relief opening 51 to the outer side of the face cover 5. The inner periphery of the face cover 5 is engaged with the periphery of the outer plate 2 so as to cover the outer plate 2 and the connection between the outer plate 2 and the inner plate 3 through the face cover 5, thereby enhancing the visual unity of the front of the charging device.
[0037] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
