Charging socket

The present invention relates to a charging socket, and more particularly to a charging socket that is connected to a DC power source and disposed in a fixed position to provide USB charging of different electrical devices.

Under the trend of digitalization, electrical equipment such as digital assistants (PDAs), mobile phones, digital video cameras, walkmans, and lights have become quite common. Currently, the commonly used interface standard is universal serial bus (USB). ) to provide both data transmission and charging functions. Therefore, when the manufacturer of electrical equipment sells, the charger will be included in the standard equipment to provide charging for the battery of the electrical equipment.

In general, the charging method of the electrical device usually requires an external charger to be connected to the AC power source, and is rectified and stepped down by the circuit in the charger, and then connected to the electrical device through a wire and a plug. Charging the battery. However, when a user replaces a new electrical device with a purchase, or has multiple different types of electrical equipment at the same time, the following problems may occur due to the proliferation of various chargers: 1. When the user has multiple different types at the same time When the charger is installed, it increases the storage space and is confusing. 2. When the charger is damaged or lost, since the chargers cannot be used instead, the user needs to re-purchase, resulting in an increase in the purchase cost and waste of resources. 3. Although the user can directly charge by the charger, since there is no fixed charging position, not only the charger needs to be obtained when charging, but also the charging socket needs to be found, which is quite inconvenient in practical use. 4. When the user uses the charger, if only the electrical equipment is removed, When you continue to leave the charger on the socket, it will continue to consume power, resulting in waste of energy.

In response to the above problems, the "Buried Charging Socket" of Taiwan Patent Publication No. M376027 has provided a solution. However, for USB adapters used outdoors or on vehicles, their structure cannot be effectively transferred.

Referring to Figures 1-3, a preferred embodiment of the charging socket 1 of the present invention includes a housing 2, a crimping switch 3, a circuit board 4, and a movable base 5.

The housing 2 is substantially rectangular parallelepiped for correspondingly embedded in a rectangular positioning slot provided by a device. When implemented, the device is mainly a vehicle, and the device can also be other movable or non-movable objects located outdoors or indoors. . The housing 2 is provided with a receiving space 21 having an opening 211. In Fig. 2, the opening 211 is located at the top of the casing 2, and the opening 211 is located at the bottom of the casing 2 when actually mounted on the top plate of the interior of the wheeled vehicle. This embodiment will be described in such a manner that the opening 211 is located at the top of the casing 2.

The buckle switch 3 is received in the accommodating space 21 of the casing 2, and one side of the buckle switch 3 is provided with a DC input terminal 31 and a DC output terminal 32. The DC input terminal 31 is electrically connected to the battery of the vehicle. The top end of the buckle switch 3 is provided with a pressing portion 33 that can be lifted up and down. When the pressing portion 33 is pressed a single time, the DC input terminal 31 and the DC output terminal 32 are turned on, and when the pressing portion 33 is pressed again, the DC input terminal 31 and the DC output terminal 32 are disconnected. The above structures are generally combined into separate components, and the specific structure thereof has been disclosed, for example, in the Taiwan Invention Invention No. "I233133" "pressing switch" or the Taiwan new type "205388" "pressing switch" In the patent specification, although the two have different structures, the same can be achieved by the buckle switch 3 of the present invention controlling the direct current input end 31 and the direct current output end 32 to be in an open or open state, and the specificity of the buckle switch 3 is achieved. The structure may be in other forms and, therefore, is not limited in the present invention.

In the implementation, the buckle switch 3 can also include an up and down lift driver 34 and a switch 35 as shown in FIG. 4, wherein the pressing portion 33 is formed at the top end of the up and down lift driver 34, and the switch 35, the DC input terminal 31 and the DC output terminal 32 are simultaneously connected, and the pressing portion 33 can also be pressed to control the DC input terminal 31 and the DC output terminal 32 to be in an on or off state. However, in each of the embodiments of the push button switch 3, the combination of the upper and lower lifting drive 34 and the switch 35 as an integral push button switch 3 can not only save space, but also facilitate assembly, and therefore is a preferred choice.

The circuit board 4 is disposed in the accommodating space 21 of the housing 2, and the circuit board 4 has a step-down circuit 41 and a voltage stabilizing circuit 42 electrically connected thereto, and the voltage stabilizing circuit 42 and the DC output terminal 32 of the shackle switch 3 are The electrical connection is such that when the direct current input terminal 31 and the direct current output terminal 32 are in an on state, the DC voltage input from the direct current input terminal 31 is lowered to output a stable direct current of about 5 volts.

The movable base 5 is substantially fan-shaped and is received and positioned on the opening 211 of the casing 2 and coupled to the upper end of the pressing portion 33. The movable base 5 has a small end portion 51 and an arcuate portion 52. The small end portion 51 is pivotally connected to one side of the housing 2, so that the movable seat body 5 can pivot up and down as a mandrel; Two universal serial bus (USB) slots are embedded in the shape 52, and the two USB slots are electrically connected to the circuit board 4, and the USB socket is used as the socket 53. In practice, the docking station 53 can also be set to one or two or more. On the top surface of the movable base 5, a power indicator light 54 is provided, and the power indicator light 54 is electrically connected to the circuit board 4.

Thereby, as shown in FIGS. 5 and 6, when the user presses the movable base 5 to interlock the pressing portion 33 and exposes the socket 53, the electrical device having the USB connector can be plugged in, for example, a digital individual. Assistant (PDA), mobile phone, digital video camera, MP3, MP4 player, etc., and let the DC input terminal 31 and the DC output terminal 32 be turned on to provide a 5 volt DC power output. At this time, the power supply indication The light 54 simultaneously emits light; and when the movable base 5 is pressed again to hide the socket 53 in the accommodating space 21 of the casing 2, the pressing portion 33 can be interlocked to allow the DC input terminal 31 and the DC output terminal 32 to be Open circuit state, at this time, the socket 53 stops the power supply, and the electricity The source indicator 54 is off.

Therefore, the present invention has the following advantages:

1. The invention can be directly fixed inside the vehicle to provide USB charging of different electrical devices, and therefore, it is quite convenient to use.

2. The invention can expose the socket when charging is needed, and hide the socket when charging is not needed. Therefore, it is convenient to use and beautiful, and can effectively avoid the influence of dust and moisture when hidden. Reduce the chance of product failure.

3. The invention can make the plug socket in a chargeable state when the plug socket is exposed, and the plug socket is in an open state when the plug socket is hidden, thereby effectively saving energy and ensuring safe use.

In summary, according to the above disclosure, the present invention can achieve the intended purpose, and provides a charging socket which is not only convenient to use, beautiful, and can effectively save energy, and ensures safe use, and is highly utilized in the industry.
