Description

Charging device

The invention relates to a charging device, in particular to a charging device having a plurality of charging slots.

At present, electronic devices (for example, police secret recorder, personal digital assistant PDA, or mobile phone) need to be charged through a charging socket inserted into a single slot or multiple slots. During the charging process, the electronic components inside the electronic device and parts such as the battery will increase the temperature. In order to prevent excessive temperature from damaging electronic components and batteries and reducing the service life of the electronic device, a fan is often provided in the charging base to reduce the temperature of the electronic device.

Taking a charging base with multiple charging slots as an example, a fan is often arranged in the base of the charging base, and the airflow generated by the fan flows along the flow channel formed by the base and flows beside the charging slot to reduce the electronics. Device temperature. However, charging cradles with multiple charging slots are not always fully filled with electronic devices. If only one electronic device is inserted into a charging cradle with multiple charging slots, the airflow from the fan will still be next to all charging slots. The flow path shuttles, making it difficult for the airflow to focus on the heat dissipation of the electronic device, thereby reducing the cooling effect of the fan.

The present invention is to provide a charging device, so as to solve the problem that when a charging base with multiple charging slots in the prior art is inserted into only one electronic device, it still shuttles through the flow channels beside all the charging slots.

A charging device disclosed in an embodiment of the present invention is applicable to at least one electronic device, and includes a charging base, a first airflow gate and a second airflow gate. The charging base includes a body, a first charging slot and a second charging slot. The first charging slot and the second charging slot are disposed on the base body, so that a main channel, a first tributary channel, and a second tributary channel are formed in the base body. The first branch runner and the second branch runner are located beside the first charging slot and the second charging slot, respectively. The first airflow gate and the second airflow gate are respectively movably located in the first tributary channel and the second tributary channel and move between a closed position and an open position, and the first airflow gate and the second airflow gate are normally in the closed position, To prevent air from flowing into the first tributary and the second tributary. Wherein, when at least one electronic device is inserted into the first charging slot, the first airflow gate is moved from the closed position to the open position, so that the airflow autonomously flows into the first branch flowpath.

According to the charging device disclosed in the above embodiment, each airflow gate is normally maintained in a closed position, and when the electronic device is inserted into the first charging slot, the electronic device will remove the first airflow gate separating the first tributary channel from the main flow channel from The closed position is moved to the open position, so that the airflow located in the main flow channel can be concentrated to the first branch flow channel adjacent to the first charging slot being charged, thereby improving the heat radiation effect of the cooling airflow on the electronic device being charged.

The above description of the content of the present invention and the description of the following embodiments are used to demonstrate and explain the principle of the present invention, and provide further explanation of the scope of the patent application of the present invention.
