Description

Technical Field

[0002] As electrical equipment increasingly demands higher requirements for power supply quality, safety, reliability, convenience, immediacy, special occasions, and special geographical environments, contact-based power transmission methods are becoming less and less able to meet actual needs.

[0003] A wireless charger is a device that uses the principle of electromagnetic induction for charging, similar to a transformer. It involves placing a coil at both the transmitting and receiving ends. The transmitting coil emits electromagnetic signals under the influence of electricity, while the receiving coil receives these signals and converts them into electrical current, thus achieving wireless charging. Wireless charging technology is a special power supply method that eliminates the need for power cords. It relies on electromagnetic waves to propagate and convert electromagnetic energy into electrical energy, ultimately achieving wireless charging.

[0004] There are more and more types of wireless chargers, and the power is gradually increasing in order to increase charging efficiency. However, high-power charging devices often generate a lot of heat when working. If the charging device is in a high-temperature environment for a long time, it will easily affect the lifespan of electronic components. Utility Model Content

The terminology used in this specification of the present invention is for the purpose of describing specific embodiments only and is not intended to limit the present invention.

[0030] It should also be noted that in the description of this utility model, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] like Figure 1 and Figure 2 As shown, this utility model discloses an in-vehicle wireless charging device 100 that can improve heat dissipation, including a charging mechanism 10, a heat dissipation mechanism 20, and a mounting mechanism 30. The mounting mechanism 30 is used to install on a car, the charging mechanism 10 is used to charge the terminal device, and the heat dissipation mechanism 20 is used to dissipate heat from the charging mechanism 10.

[0032] The mounting mechanism 30 is used to cooperate with the corresponding mounting bracket so that the charging device can be firmly fixed on the vehicle. The specific mounting bracket is not limited here.

[0033] The heat dissipation mechanism 20 is located between the charging mechanism 10 and the mounting mechanism 30.

[0034] Specifically, the heat dissipation mechanism 20 includes a heat dissipation shell 21, a turbofan fan 22, and a heat-conducting component 23. The two ends of the heat dissipation shell 21 are respectively connected to the charging mechanism 10 and the mounting mechanism 30. The heat-conducting component 23 is fixed inside the heat dissipation shell 21 and is in communication with the charging mechanism 10. Multiple heat dissipation holes 211 are provided on the side wall of the heat dissipation shell 21. The turbofan fan 22 is fixed inside the heat-conducting component 23 and can blow air outwards. Specifically, the heat-generating component of the charging mechanism 10 is close to the heat-conducting component 23. The heat generated when the charging mechanism 10 is working can be transferred to the heat-conducting component 23. Then, the turbofan fan 22 operates, blowing air outwards, thereby accelerating the airflow speed in the environment where the heat-conducting component 23 is located. Furthermore, the air is blown outwards through the heat dissipation holes 211, thus achieving heat exchange and accelerating heat dissipation.

[0035] Furthermore, the mounting mechanism 30 includes a mounting plate 31 and a mounting component 32. The mounting plate 31 is connected to the heat dissipation housing 21, and the mounting plate 31 is provided with a through hole 311 communicating with the heat dissipation housing 21. The mounting component 32 is fixed on the mounting plate 31. The through hole 311 is provided to cooperate with the turbofan 22, serving as an air intake channel for the turbofan 22 during operation, thus assisting the turbofan 22 in blowing air and dissipating heat.

[0036] Furthermore, in this application, the mounting component 32 can be a mounting structure with a spherical groove, used to cooperate with a spherical mounting bracket on a vehicle to realize the installation of the charging device. The mounting component 32 can adopt existing mounting structures, and there are no detailed limitations on them here.

[0037] like Figure 2 and Figure 3 As shown, the heat-conducting component 23 further includes a mounting portion 231 and a heat dissipation portion. The mounting portion 231 is fixedly connected to the charging mechanism 10. The heat dissipation portion is provided with a plurality of heat dissipation fins 232, with adjacent heat dissipation fins 232 spaced apart. The gap between adjacent heat dissipation fins 232 is connected to the heat dissipation hole 211. During operation, the heat from the charging mechanism 10 can be transferred to the mounting portion 231, and then the mounting portion 231 transfers the heat to each of the heat dissipation fins 232. Subsequently, the turbofan 22 operates to dissipate heat from the heat dissipation fins 232.

[0038] Multiple heat dissipation fins 232 are arranged in a circumferential array at the edge of the mounting portion 231; the circumferential array of the multiple heat dissipation fins 232 forms a mounting space 233, and the turbofan 22 is fixed within the mounting space 233. In this application, the turbofan 22 can blow air outwards to the circumference, and the airflow range can form a ring. Therefore, placing the turbofan 22 within the mounting space 233 formed by the heat dissipation fins 232 can improve the heat dissipation effect of the turbofan 22.

[0039] like Figure 2 and Figure 4 As shown, the charging mechanism 10 further includes a charging housing 11, a main control board 12, and a charging assembly 13. The charging housing 11 is snap-fitted into the heat dissipation housing 21. A baffle 111 is provided on the charging housing 11. The charging assembly 13 and the main control board 12 are respectively located on both sides of the baffle 111, with the main control board 12 located on the side of the baffle 111 closer to the heat dissipation mechanism 20. The heat-conducting element 23 is fixedly connected to the baffle 111. Specifically, the main control board 12 is positioned on the side of the baffle 111 closer to the heat-conducting element 23 to facilitate the transfer of heat generated by the charging mechanism 10 during operation to the heat-conducting element 23, thereby improving the heat transfer efficiency between the charging mechanism 10 and the heat dissipation mechanism 20.

[0040] Specifically, the baffle 111 is provided with a plurality of screw posts 112, and the main control board 12 has a plurality of notches corresponding to the screw posts 112 on its side periphery. The main control board 12 is positioned and engaged with the charging housing 11 through the screw posts 112; the heat-conducting component 23 is fixedly connected to the screw posts 112. The screw posts 112 not only position the main control board 12 and prevent it from shaking inside the housing, but also fix it to the heat-conducting component 23, allowing the heat-conducting component 23 to be positioned close to the main control board 12, thus improving heat conduction.

[0041] like Figure 4 and Figure 5 As shown, the heat dissipation housing 21 is provided with an annular positioning plate 212, and the inner side of the positioning plate 212 is provided with at least two slots 213. The charging housing 11 is provided with a positioning groove 113, and a buckle 114 is provided in the positioning groove 113. When the positioning plate 212 is inserted into the positioning groove 113, the buckle 114 can be engaged with the slot 213, so that the heat dissipation mechanism 20 and the charging mechanism 10 are connected as a whole.

[0042] like Figure 2As shown, in one embodiment, the main control board 12 is provided with a power terminal 121. The main control board 12 is electrically connected to an external power source through the power terminal 121. The turbofan 22 is electrically connected to the main control board 12. The external power source can supply power to the charging device through the power terminal 121, specifically, to supply power to the charging mechanism 10 and the turbofan 22.

[0043] like Figure 6 As shown, in another embodiment, the main control board 12 extends an electrical connection line 122 outward, and the turbofan 22 is electrically connected to the main control board 12. A terminal piece 123 is provided at one end of the electrical connection line 122 away from the main control board 12. The electrical connection line 122 is connected to an external power source through the terminal piece 123. The external power source can supply power to the charging device through the terminal piece 123 and the electrical connection line 122, specifically, to supply power to the charging mechanism 10 and the turbofan 22.

[0044] like Figure 2 As shown, the charging assembly 13 further includes a wireless charging module 131 and a magnet 132. The wireless charging module 131 is fixed to the charging housing 11 and electrically connected to the main control board 12. The magnet 132 is fixed to the charging housing 11 to attract a mobile terminal placed on the charging housing 11. The charging assembly 13 also includes an anti-slip pad 14, which is adhered to the charging housing 11 and covers the wireless charging module 131 and the magnet 132. During operation, after the mobile terminal is placed on the anti-slip pad 14, the magnet 132 can attract the terminal device, and then the wireless charging module 131 is used to charge the terminal device.

[0045] In this application, the terminal device may be a mobile phone, tablet computer, or other terminal device.

[0046] This utility model can be implemented and modified in various ways without departing from the general spirit and scope of this utility model. The above-described embodiments are used to illustrate the utility model, but do not limit the scope of this utility model.
