Description

Charging device having heat dissipation {CHARGE APPARATUS HAVING HEAT EMISSION PROPERTY}

The present invention relates to a charging device having heat dissipation properties, and more particularly, is installed on a bike or the like to enable wired/wireless charging to a charging object including a mobile phone, while effectively dissipating heat generated during charging to a charging object. It relates to a charging device having heat dissipation properties so that charging can be performed more smoothly.

Recently, devices such as navigation devices, PMP (portable media player) players, PDA (personal digital assistants), DMB (digital multimedia broadcasting) players, MP3 (MPEG audio layer-3) players, electronic dictionaries, and mobile phones have been miniaturized. At the same time, there is a trend toward integration of functions.

In particular, as the functions of devices such as mobile phones and tablet PCs are expanding, cases of using devices such as those used at home or offices for navigation and the like are increasing even when moving in a car or the like.

Recently, as a rapidly developing business centered on large domestic cities, 'delivery brokerage service' is prevalent, which replaces the delivery service of restaurants and pays monthly membership fees and delivery fees from franchisees (stores) to pay to agents.

For restaurants that did not provide delivery services due to the development of the food service industry, such as small business owners and small franchises, it is necessary to use an agency rather than hiring a delivery driver belonging to a restaurant according to sales along with the expansion of sales area and reduce expenses and delivery staff. It is gaining popularity because it is free from responsibility for accidents.

Bikes (motorcycles, electric bicycles) are mainly used to perform such delivery services, and at least two mobile phones are mounted on cradle and used for navigation and delivery order purposes.

However, there is a cumbersome problem in that the mobile phone mounted on the bike must be charged using a rechargeable battery or by connecting a connection terminal to the constant power of the bike.

As a prior art that partially improves these problems, Korean Utility Model Registration No. 20-0493992 (July 12, 2021) discloses a 'wireless charging device for mobile phones for motorcycles'.

However, such a conventional mobile phone wireless charging device has a problem in that it is difficult to charge a mobile phone that is not wirelessly charged because only wireless charging is possible.
