Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a dustproof and waterproof high-power vehicle-mounted wireless charger with an inclined heat dissipation air duct. Background Art

[0002] In the field of in-vehicle charging devices, traditional high-power wireless chargers often use bottom air outlets for heat dissipation. The original intention of this design was to reduce the temperature rise of mobile phones during charging by directly dissipating heat from the charger. However, in practice, it has exposed some significant problems. For example, Chinese patent CN115604984A discloses a method, device, heat dissipation device, vehicle, and storage medium for in-vehicle wireless chargers. The main structure and principle include components such as a wireless charging module, a control circuit board, a cooling fan, and a bottom air outlet. The wireless charging module is responsible for providing wireless charging for mobile devices such as mobile phones. The control circuit board controls the entire charging process, and the cooling fan dissipates heat from the charger through the bottom air outlet. The operating principle is that during charging, heat generated by the wireless charging module is transferred to the control circuit board and surrounding structures via heat conduction. When the cooling fan is activated, the heat is discharged through the bottom air outlet, thereby achieving heat dissipation. However, existing in-vehicle wireless chargers all have the following problems: 1. Dust accumulation: The bottom air outlet design allows dust to easily enter the charger from the vehicle's interior. Long-term accumulation can affect the heat dissipation and may even cause the fan to clog. 2. Water ingress: When drinking bottled water from the cup holder or washing your car, the bottom air vents can potentially allow water to enter the charger, increasing the risk of short circuits or damage. 3. Limited heat dissipation efficiency: Although a cooling fan is designed, the location of the air vents and the design of the air duct make it difficult to further improve heat dissipation efficiency. The phone may still overheat, especially in high-temperature environments. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide a vehicle-mounted wireless charger with an inclined heat dissipation air duct, which is used to improve user experience and product safety through an innovative inclined heat dissipation air duct design, so as to overcome the shortcomings of the above-mentioned prior art.

[0004] The utility model provides a vehicle-mounted wireless charger with an inclined heat dissipation duct, comprising: an upper supporting plate for the vehicle-mounted wireless charger installed in the storage compartment of the central armrest of the seat, and a wireless charger main body installed below the upper supporting plate. The utility model is characterized in that a heat dissipation duct is provided on the upper supporting plate, and the heat dissipation duct is provided at the upper end of the upper supporting plate. A protrusion is provided on the upper supporting plate and around the heat dissipation duct, and a downwardly inclined supporting surface is provided on the top of the protrusion. The wireless charger main body charges a mobile phone placed on the upper supporting plate, and the mobile phone is placed on the inclined supporting surface of the protrusion, so that the inclined supporting surface of the protrusion, the heat dissipation duct and the mobile phone form an air duct for heat dissipation.

[0005] As a preferred embodiment of the present invention, the upper bearing plate and the upper panel of the central armrest storage partition are integrally formed.

[0016] The reference numerals include: upper bearing plate 1 , heat dissipation vent 2 , and protrusion 3 . DETAILED DESCRIPTION

[0017] See Figure 1-4 As shown, this embodiment provides an in-vehicle wireless charger with an inclined heat dissipation duct, comprising: an upper carrier plate 1 for the in-vehicle wireless charger, mounted in the center armrest storage compartment; and a wireless charger body mounted below the upper carrier plate 1. The upper carrier plate 1 can be embedded with a wireless charging coil for the wireless charger body, or a wireless charging coil can be mounted below the upper carrier plate 1. The upper carrier plate 1 defines a heat dissipation duct 2, located at the upper end of the upper carrier plate 1. Protrusions 3 are provided on the upper carrier plate 1 and around the heat dissipation duct 2. A downwardly inclined support surface is provided on the top of the protrusion 3, with an angle of 15° to 30°. The wireless charger body charges a mobile phone placed on the upper carrier plate 1. The mobile phone is placed on the inclined support surface of the protrusion 3, so that the inclined support surface of the protrusion 3, the heat dissipation duct 2, and the mobile phone form a heat dissipation duct. The upper carrier plate 1 is attached to the center armrest storage compartment panel via snaps on both sides.

[0018] Working Principle: The inclined support surface of protrusion 3 on upper support plate 1 is slightly higher than the upper end surface of upper support plate 1, so that the air outlet of heat dissipation vent 2 is slightly higher than the inclined support surface. When a mobile phone is placed on the inclined support surface, an air duct is naturally formed between the air outlet and the mobile phone. Combined with the cold air outlet of the vehicle air conditioner (if necessary, it can be connected to the cold air duct of the vehicle air conditioning system), it forms an efficient heat exchange system, quickly removing heat generated during charging and ensuring that the temperature of the mobile phone is always controlled within a safe range. In addition, the design of heat dissipation vent 2 above upper support plate 1 not only prevents dust accumulation, but also significantly reduces the risk of water flowing into the car cup holder when drinking water or cleaning the car interior.

[0019] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
