Description

一种大功率无线充电器及车载充电结构A high-power wireless charger and vehicle-mounted charging structure 技术领域Technical Field
本实用新型涉及车载无线充电器领域，具体涉及一种大功率无线充电器及车载充电结构。The utility model relates to the field of vehicle-mounted wireless chargers, and in particular to a high-power wireless charger and a vehicle-mounted charging structure.
背景技术Background technique
近年来，随着车载无线充电技术的发展，汽车出厂时搭载无线充电已成为大众趋势。而随着手机的更新迭代及国产手机的崛起，越来越多的手机电子设备具备大功率无线充电功能。然而现在车厂配置的车载无线充电器大多只能为电子设备提供小功率的无线充电功能，充电时间过长，用户体验不佳。In recent years, with the development of in-vehicle wireless charging technology, it has become a popular trend for cars to be equipped with wireless charging when they leave the factory. With the update and iteration of mobile phones and the rise of domestic mobile phones, more and more mobile electronic devices have high-power wireless charging functions. However, most of the in-vehicle wireless chargers configured by car manufacturers can only provide low-power wireless charging functions for electronic devices, and the charging time is too long, and the user experience is not good.
传统的车载无线充电由于在充电过程中发热严重且手机有各自不同的过温保护的逻辑，导致充电过程中出现①车载无线充电本体发热严重，无线充电总成自动限制功率，导致电子设备充电时间长且无法缩短；②电子设备表面温度过热、充电时间较长且无法缩短，现在车厂配置的车载无线充电器大多只能为电子设备提供小功率无线充电功能，要实现大功率无线充电的功能得先解决车载无线充电器本体和电子设备发热问题。Traditional in-car wireless charging generates severe heat during the charging process and mobile phones have their own different over-temperature protection logic, which leads to the following problems during the charging process: 1. The in-car wireless charger body generates severe heat and the wireless charging assembly automatically limits the power, resulting in a long charging time for the electronic device that cannot be shortened; 2. The surface temperature of the electronic device overheats, resulting in a long charging time that cannot be shortened. Currently, most of the in-car wireless chargers configured by car manufacturers can only provide low-power wireless charging functions for electronic devices. To achieve high-power wireless charging functions, the heating problem of the in-car wireless charger body and the electronic equipment must be solved first.

The upper cover 1 and the base 40 are connected to form an accommodating space. The charging component 300 is arranged in the accommodating space and connected to the base 40. A radiator 50 is installed on the base 40. The radiator 50 has a first end face 51 and a second end face 52.

When current passes through the semiconductor cooling sheet 60, heat transfer will occur at both ends, thereby generating a temperature difference to form the cold end 62 and the hot end 61. When the cold end 62 and the hot end 61 reach a certain temperature difference, a balance point will appear, the cold end 62 absorbs heat, and the hot end 61 dissipates heat. When the temperature of the hot end 61 is high, the semiconductor cooling sheet 60 plays a role, so that the temperature of the cold end 62 and the hot end 61 gradually balances.

本实用新型一种大功率无线充电器以及车载充电结构工作原理及过程，无线充电器100工作时，线圈组件310和PCBA主控板320产生热量传导至底座40，热量通过散热器50和散热鳍片10散发，与散热器50贴合的半导体制冷片60的热端61温度升高，半半导体制冷片60发挥作用，当第一风扇72吹出的风经过半导体制冷片60的冷端62，冷端62的温度降低，热端61的温度也相应的降低，降低温度后的风吹向容置空间，散热鳍片10的位置安装有第二风扇9加速对底座40的散热，由于在上盖1上需要加装防滑垫11，所以在上盖1靠近第一风道17的位置开通风口16，使得第一风道17的风经过通风口16到达防滑垫11的底部，实现了对电子设备200的散热，同时对无线充电器100的本体和电子设备200进行散热能够减少功率的限制，提高充电的效率。The utility model discloses a high-power wireless charger and a working principle and process of a vehicle-mounted charging structure. When the wireless charger 100 is working, the coil assembly 310 and the PCBA main control board 320 generate heat and conduct it to the base 40. The heat is dissipated through the radiator 50 and the heat dissipation fins 10. The temperature of the hot end 61 of the semiconductor refrigeration plate 60 attached to the radiator 50 increases, and the semi-semiconductor refrigeration plate 60 plays a role. When the wind blown out by the first fan 72 passes through the cold end 62 of the semiconductor refrigeration plate 60, the temperature of the cold end 62 decreases, and the temperature of the hot end 61 also decreases accordingly. The wind with reduced temperature blows toward the accommodating space. The second fan 9 is installed at the position of the heat dissipation fin 10 to accelerate the heat dissipation of the base 40. Since the anti-skid pad 11 needs to be installed on the upper cover 1, the vent 16 is opened at the position of the upper cover 1 close to the first air duct 17, so that the wind of the first air duct 17 passes through the vent 16 to reach the bottom of the anti-skid pad 11, thereby realizing the heat dissipation of the electronic device 200. At the same time, the heat dissipation of the body of the wireless charger 100 and the electronic device 200 can reduce the power limitation and improve the charging efficiency.
