Wireless charging device
[0001] Cross-references to related applications
[0002] This disclosure claims priority to U.S. Patent Application No. 63 / 716,729, filed November 6, 2024, entitled “Wireless Charging Device,” the entire contents of which are incorporated herein by reference. Technical Field
[0003] This disclosure relates to a charging device, and more particularly to a wireless charging device such as one for vehicles. Background Technology
[0004] Current wireless charging products for cars mostly use MPP 2.0 and similar technologies to charge mobile phones or devices like iPhones (12 rows and above) via magnetic attraction. During charging, the phone or device is magnetically positioned on the charging dock. However, when using non-magnetic phones or devices like Android phones and iPhones (8 to 11 rows) using EPP 2.0 or similar technologies, there is no way to position the phone. Therefore, during driving, the inertia caused by braking or turning can cause the phone or device to shift off the charging dock, easily leading to reduced charging efficiency or even preventing charging altogether.
[0005] Furthermore, when a wireless charging pad is splashed with liquid, existing charging pads are susceptible to liquid intrusion through their ventilation or heat dissipation vents, potentially causing malfunctions. Additionally, the charging pad itself heats up when charging mobile devices such as smartphones; therefore, without cooling mechanisms like ventilation or heat dissipation vents, charging efficiency will be reduced.
[0006] In view of this, in order to improve and solve the above-mentioned shortcomings, the present disclosure has devoted itself to research and application of scientific theories, and finally proposed a reasonable design that effectively improves the above-mentioned shortcomings. Summary of the Invention
[0007] The main objective of this disclosure is to provide a wireless charging device that can be used to charge mobile devices such as mobile phones in vehicles, and has heat dissipation structures such as vents to cool the wireless charging module in order to maintain its charging efficiency, while also achieving waterproof and dustproof effects.
[0008] Another object of this disclosure is to provide a wireless charging device that optionally provides an anti-slip function, enabling positioning during charging to avoid displacement due to inertia during vehicle movement, thereby maintaining good charging efficiency.
[0009] Another object of this disclosure is to provide a wireless charging device that can bypass the camera lenses or photographic modules of various mobile devices, thereby increasing its applicability to different types of mobile devices and thus having wide applicability.
[0010] To achieve the above objectives, this disclosure provides a wireless charging device, including a housing, a wireless charging module, and a sealing mechanism. The housing has a placement surface and a plurality of vent holes, and the housing has an installation space adjacent to and opposite the placement surface. The wireless charging module is disposed in the installation space relative to the placement surface, and the vent holes are arranged around the placement surface. The sealing mechanism is disposed in the housing and has a connecting member and a plurality of sealing plugs disposed on the connecting member. Each sealing plug corresponds to a vent hole, and the connecting member can move relative to the placement surface so that each sealing plug closes or opens a vent hole. Attached Figure Description

Detailed Implementation
[0024] To enable your review committee to further understand the features and technical content of this disclosure, please refer to the following detailed description and accompanying drawings. However, the accompanying drawings are provided for reference and illustration only and are not intended to limit this disclosure.
[0025] Please refer to Figures 1 and 2, which are respectively an exploded perspective view of this disclosure and an exploded perspective view of this disclosure and a mobile device. This disclosure provides a wireless charging device 1, which can be configured to charge a mobile device 3 wirelessly, and the mobile device 3 can be a portable mobile device such as a smartphone or tablet. Referring to Figure 3, the wireless charging device 1 includes a housing 10, a wireless charging module 11, and a sealing mechanism 12; wherein:
[0026] As shown in Figure 3, the housing 10 of the wireless charging device 1 is used to house the wireless charging module 11 and the sealing mechanism 12. The housing 10 has an upward-facing surface 100, and a placement platform 101 protrudes from the center of the surface 100. The placement platform 101 may be hollow and annular, and a placement surface 101a is provided on it. An installation space 101b is formed below the placement surface 101a and is located in the placement platform 101, so that the wireless charging module 11 can be placed in the installation space 101b and close to or adjacent to the area below the placement surface 101a. The housing 10 also has multiple vent holes 102 on its surface 100, extending into the housing 10. Each vent hole 102 connects to the mounting space 101b through the housing 10. One or more exhaust holes 103 can be provided on other surfaces of the housing 10 (such as the bottom surface) and connected to the interior of the housing 10. This allows for the addition of a fan 13 located at the exhaust hole 103 to facilitate airflow and provide cooling for the wireless charging module 11 located in the mounting space 101b. Furthermore, the fan 13 can be located outside the housing 10 corresponding to the exhaust hole 103, or it can be located inside the housing 10 corresponding to the exhaust hole 103; therefore, it is not limited to the figures provided in this disclosure.
[0027] Referring again to Figure 1, the ventilation holes 102 on the housing 10 of the wireless charging device 1 can be arranged around the placement platform 101 in accordance with its position. In the embodiments described in this disclosure, the ventilation holes 102 can be arranged on both sides of the placement platform 101, that is, the ventilation holes 102 are arranged in a row on both sides of the placement platform 101, and the two rows of ventilation holes 102 are opposite to each other. Optionally, the wireless charging device 1 may further include an anti-slip structure 2, which may be made of a material such as rubber, and has a pad 20 and a plurality of anti-slip protrusions 21 provided on the pad 20. The pad 20 is provided with a through portion 200 corresponding to the placement platform 101. The through portion 200 is a through hole that matches the shape of the placement platform 101, so that the pad 20 can be stacked on the surface 100 of the housing 10 through the through portion 200 of the placement platform 101, and the anti-slip protrusions 21 contact the back of the mobile device 3 together to prevent the mobile device 3 from shifting during charging due to the inertia of the vehicle, which would reduce the charging efficiency of the wireless charging module 11.
[0028] As described above, the anti-slip structure 2 also has a plurality of air inlets 22 on the pad body 20 and penetrates the pad body 20. In an embodiment not shown in the figures, each air inlet 22 can directly correspond to each vent hole 102, so that external air can enter the housing 10 through the pad body 20. In the embodiment of this disclosure, as shown in FIG3, on the surface 100 of the housing 10, a recess 104 is provided on the side of each row of vent holes 102 away from the placement platform 101, and a stop 104a is formed between each recess 104 and the corresponding row of vent holes 102, so that the bottom surface of the recess 104 is lower than the upper end of each row of vent holes 102. Meanwhile, each row of air inlets 22 of the pad 20 corresponds to and is covered by the area formed by each recess 104, and each row of air inlets 22 extends toward each vent 102. For example, one or more channels 220 connecting each air inlet 22 and each vent 102 are provided below the pad 20. This design not only provides the wireless charging device 1 with the necessary airflow between each vent 102 and the outside air when the anti-slip structure 2 is added, but also allows the recess 104 to be configured to collect a small amount of water splashed onto the air inlets 22 from the outside, and to block the water from flowing into the vent 102 with the baffle 104a, thereby preventing water from seeping into the housing 10 and affecting the electronic components inside the wireless charging device 1, thus ensuring its normal operation.
[0029] As shown in Figures 3 and 4, the wireless charging module 11 of the wireless charging device 1 is located inside the housing 10, specifically within the installation space 101b and close to or adjacent to the placement surface 101a below, and is used to charge the mobile device 3. The wireless charging module 11 can be electromagnetic induction type, mainly composed of coils and circuit chips, and is used to identify the mobile device 3 to send or transmit electrical energy to it.
[0030] Referring again to Figures 3 and 4, the sealing mechanism 12 of the wireless charging device 1 is also mainly located inside the housing 10, and has a connecting member 120 and a plurality of sealing plugs 120a provided on the connecting member 120. Each sealing plug 120a corresponds to the lower part of each vent hole 102, and the connecting member 120 can move relative to the placement surface 101a so that each sealing plug 120a is closed towards each vent hole 102 (as shown in Figure 3) or opened away from each vent hole 102 (as shown in Figure 4). Optionally, the closing mechanism 12 can also drive the connecting member 120 to make the aforementioned relative movement through a trigger component 121, and the trigger component 121 has at least a trigger component 121a and an actuating component 121b; in the embodiments of this disclosure, the trigger component 121 can be a protrusion disposed on the connecting member 120, and can have a housing perforation 105 on the housing 10 for it to move through, and a pad perforation 23 on the pad 20 corresponding to the housing perforation 105 for it to move through, and the protrusion protrudes from the pad perforation 23 and extends above the placement surface 101a, the part of it that is above the placement surface 101a is the trigger component 121a, and the part used to connect the connecting member 120 to the trigger component 121a is the actuating component 121b. Therefore, when the mobile device 3 is placed on the placement surface 101a for charging, the mobile device 3 can use its own weight to press the triggering component 121a downwards, thereby pushing the actuating component 121b to push the connecting component 120 downwards. This causes the sealing plugs 120a on the connecting component 120 to leave the vent holes 102, allowing all the vent holes 102 to open during the charging process, providing external air into the housing 10 for heat dissipation or cooling. Conversely, when the mobile device 3 is picked up, a return mechanism can be used to push the connecting component 120 upwards, causing the sealing plugs 120a to close the vent holes 102. The return mechanism can be one or more elastic components that, when the mobile device 3 is not placed, elastically push the connecting component 120 upwards, so that the vent holes 102 can have waterproof or dustproof functions when not charging.
[0031] Furthermore, in other feasible embodiments, the triggering component 121a of the aforementioned actuation component 121 can also be a sensor, and can be disposed on the surface 100 or placement surface 101a of the housing 10, so that when the mobile device 3 is placed on the placement surface 101a, it can sense the mobile device 3 and drive its actuating component 121b to drive the connecting component 120 to actuate. The actuating component 121b can be various transmission components or combinations thereof, such as a motor driving a component such as a screw to drive the connecting component 120 to move up and down. Alternatively, the actuating component 121b can also be a solenoid valve or an electromagnetic component. The sensor determines whether the mobile device 3 is placed on the placement surface 101a and sends a signal to the actuating component 121b to perform a corresponding action, such as using magnetic repulsion to push the connecting component 120 away, or using magnetic attraction to make the connecting component 120 move towards each vent 102, which can also achieve the same technical effect as described above.
[0032] Therefore, the wireless charging device disclosed herein can be obtained through the above-described structure.
[0033] As shown in Figures 5 and 6, this disclosure optionally designs mobile devices 3 that can be applied to more types or styles. In the first embodiment of the mobile device 3, it has a camera module 30 located on one side above its back. The anti-slip structure 2 disclosed herein arranges the anti-slip protrusions 21 on the pad 20 according to the two sides of the insertion part 200 or the placement platform 101. That is, the anti-slip protrusions 21 are arranged in a row on the two sides of the insertion part 200 or the placement platform 101, and the lengths of the anti-slip protrusions 21 are different and close to the insertion part 200 or the placement platform 101. The distance L formed by the anti-slip protrusions 21 in the row is greater than the distance l formed by the anti-slip protrusions 21 in the other row, and the anti-slip protrusions 21 in the other row are biased to one side on the pad 20 to form a clearance space 21a, thereby providing a place for the camera module 30 of the mobile device 3. The second and third embodiments of the mobile device 3 shown in FIG7 and FIG8 are thus applicable.
[0034] Referring again to Figures 5 and 6, further, the minimum distance D between each anti-slip protrusion 21 in the other row and its adjacent air inlet 22 is greater than the minimum distance d between each anti-slip protrusion 21 in the first row and its adjacent air inlet 22. Thus, it can be applied to more different types of mobile devices 3. That is, as shown in Figures 9 to 12, it can also be further applied to the fourth to seventh embodiments of the mobile device 3.
[0035] Therefore, the wireless charging device disclosed herein can be used to charge mobile devices 3 such as mobile phones in vehicles. It allows for heat dissipation through a vent 102 during charging and closes the vent 102 when not charging, thus providing waterproofing and dustproofing. It also provides anti-slip positioning during charging and prevents displacement due to inertia during vehicle movement. Furthermore, its design avoids the camera lenses or imaging modules 30 of various mobile devices 3, increasing its applicability to different types of mobile devices 3 and thus achieving wide applicability.
[0036] In conclusion, this disclosure does indeed achieve the intended use described in the above specification and overcomes the shortcomings of known inventions. Furthermore, due to its novelty and inventiveness, it fully meets the requirements for an invention patent application. Therefore, this application is filed in accordance with the Patent Law. We respectfully request a thorough review and the granting of this patent to protect the inventor's rights.

Therefore, all equivalent technical and technical changes made using the content of this disclosure and its drawings are also included within the scope of this disclosure and are hereby stated.
