Description

Technical Field

[0001] The present application relates to an external vehicle power supply device, and more particularly to a power supply device capable of continuing to charge while the vehicle is parked. Background Art

[0002] Thanks to the advancement of electronic technology, many 3C (Computer, Communication, Consumer Electronics) electronic devices have been integrated into vehicles, adding to driving convenience. These devices include dashcams, Bluetooth, 3G (3rd Generation Mobile Communication Technology) positioning, Wi-Fi (Wireless Fidelity) sharing, emergency video storage, and night photography. While these devices don't require significant power, they are powered by the car's cigarette lighter (battery).

[0003] When the car is turned off, the power supply stops and the device stops being used. Alternatively, the device can be set to continue using the car battery after the car is turned off. Short-term use may not have much effect on restarting the vehicle. However, if the vehicle is parked or turned off for too long, the continuous power consumption of the related devices will cause insufficient power in the vehicle battery, or even make the vehicle unable to start. The above and other inconveniences limit the convenience of using these external devices.

[0004] Therefore, how to improve the situation in which the vehicle is parked for too long or turned off for too long so that the external device can be started and used without the vehicle battery is the problem to be solved by this application. Utility Model Content

[0039] The technical content and detailed description of this application are now described as follows with reference to the accompanying drawings:

[0040] See also Figure 1 , a circuit block diagram of the power supply device of the present application. As shown in the figure: the solar parking power supply device of the present application includes: a host circuit board 10. The host circuit board 10 includes: a controller 101 and a power storage unit 102, and the controller 101 and the power storage unit 102 are electrically connected to the host circuit board 10. After receiving solar power, when the vehicle is parked, it can provide 3C products such as driving recorders, Bluetooth devices, navigation systems or Wi-Fi devices with the power required for driving recording, Bluetooth functions, 3G positioning, wireless Wi-Fi sharing, SOS emergency video storage function and night shooting function.

[0041] The controller 101 includes a processor 1011 , a vehicle power receiving unit 1012 , a power storage control unit 1013 , and a power output unit 1014 .

[0042] The processor 1011 receives signals outputted by each unit to control the storage and output of power. In this figure, the processor 1011 is a central processing unit, a digital signal processor, a microprocessor, a graphics processor or a microcontroller.

[0043] The vehicle power receiving unit 1012 is electrically connected to the processor 1011 and the vehicle power input terminal (cigarette lighter female connector) 40. It receives power from the vehicle and transmits it to the processor to provide the power required for the solar parking power supply device to operate and control the device. In this figure, the vehicle power receiving unit 1012 is a cigarette lighter male connector.

[0044] The power storage control unit 1013 is electrically connected to the processor 1011 to receive the power output by the solar panel 30 through the processor 1011 . Under the control of the processor 1011 , the power storage control unit 1013 can charge the power storage unit 102 .

[0045] The power output unit 1014 is electrically connected to the processor 1011. After the power storage unit 102 transmits power to the processor 1011, the processor 1011 transmits the power to the power output unit 1014, allowing the power output unit 1014 to output power. In this figure, the power output unit 1014 is a female cigarette lighter connector (female power socket).

[0046] The power storage unit 102 is electrically connected to the power storage control unit 1013. The power storage unit 102 receives and stores power output by the power storage control unit 1013. In this figure, the power storage unit 102 is a rechargeable battery or a super capacitor.

[0047] See also Figure 2 , the solar parking power supply device of the second embodiment of the present application is installed inside the housing and connected to the solar panel; refer to Figure 1 As shown in the figure, the solar parking power supply device of the present application further includes: a housing 20 and a solar panel 30. The main circuit board 10 is installed inside the housing 20, so that the solar parking power supply device can be installed in the vehicle for use.

[0048] The host circuit board 10 is mounted on the housing and electrically connected to a transmission line 301. This transmission line 301 passes through the housing 20 and is secured thereto. The other end of the transmission line 301 extends outside the housing 20 and electrically connects to the solar panel 30. The solar panel 30 receives sunlight, converts it into electricity, and transmits it to the power storage control unit 1013, which then charges the power storage unit 102.

[0049] Furthermore, the vehicle power receiving unit 1012 is mounted on the housing 20 and electrically connected to the host circuit board 10 via a wire 10121. Alternatively, the vehicle power receiving unit 1012 is not mounted on the housing 20 and is electrically connected to the host circuit board 10 via the wire 10121 passing through the housing 20. Since the vehicle power receiving unit 1012 is a male cigarette lighter connector, it is plugged into the vehicle power input terminal (female cigarette lighter connector) 40 inside the vehicle to input vehicle power to the host circuit board 10. The host circuit board 10 then outputs the vehicle power to the power output unit 1014, or the vehicle power can be stored in the power storage unit 102.

[0050] In addition, a power output unit 1014 and a USB connector 1015 are mounted on the housing 20, exposing the interfaces of the power output unit (power socket) 1014 and the USB connector 1015. These interfaces allow for connection to devices such as a dashcam, Bluetooth device, navigation system, or Wi-Fi device, or for charging or powering a mobile device (not shown). In this figure, the USB connector 1015 is a USB Type A, USB Type B, USB Type C, Micro USB, or Mini USB.

[0051] When using the solar parking power supply device of the present application, the housing 20 is installed inside the vehicle, and the solar panel 30 is mounted on the front windshield, rear windshield, or dashboard. The solar panel absorbs sunlight, generating power output that is stored in the power storage unit 102 by the power storage control unit 1013. The power output is then output to the power output unit 1014 for use by external devices. Furthermore, the vehicle power receiving unit 1012 is plugged into the vehicle's cigarette lighter (not shown) to input vehicle power to the controller 101. The controller 101 then transmits the vehicle power to the power output unit 1014 for use by external devices.

[0052] However, the processor 1011 of the controller 101 can also detect whether the vehicle power receiving unit 1012 is receiving power. If power is received (the vehicle is in the starting state), the power input from the vehicle battery (not shown) is transmitted via the processor 1011 of the controller 101 to the power output unit 1014 for use by the external device. If power is not received (the vehicle is in the parked state), the power is transferred from the power storage unit 102 to the power output unit 1014 via the processor 1011 of the controller 101 for use by the external device.

[0053] See also Figure 3 , the third embodiment of the present application of the solar parking power supply device is installed inside the housing and connected to the solar panel schematic diagram, also refer to Figure 1 、 2 As shown in the figure: This embodiment is substantially the same as the first and second embodiments, except that at least one power indicator light 1016, a switch 1017, and a power switch 1018 can be mounted on the housing 20, and the power indicator light 1016, the switch 1017, and the power switch 1018 are electrically connected to the host circuit board 10 respectively.

[0054] After the power switch 1018 is pressed, the solar parking power supply device is started, and the power working indicator light 1016 is driven to light up to indicate that the solar parking power supply device is in working state or the power supply state of each power output unit 1014.

[0055] When the switch 1017 is pressed, the power supply mode of the solar parking power supply device is switched.

[0056] The design of the solar parking power supply device of this application has the following advantages:

[0057] 1. The original configuration of the electrical socket (power output unit 1014) is retained, and an electrical socket with more holes is provided, and the solar parking power supply device of the present application does not occupy space.

[0058] 2. The solar panel can be installed on the front or rear windshield or in front of the driving platform without blocking the driver's view. It is connected via the transmission line 301 to temporarily store the electricity converted from the solar energy in the power storage unit 102 inside the housing 20, and then provide continuous power to external devices after the vehicle is parked and the engine is turned off.

[0059] 3. In the past, external devices, such as dashcams, often failed to activate the sentry mode or collision recording function after the vehicle was parked and the engine was turned off. Alternatively, although the vehicle's power supply could continue to be used, prolonged use of the vehicle's battery (storage battery) would cause the vehicle to lose power, creating the risk of being unable to start the vehicle. If the solar parking power supply device of the present application is connected, the power supply will automatically jump to the power storage unit 102 within the solar parking power supply device after the vehicle is parked and the engine is turned off, providing continuous power for short-term use without worry.

[0060] 4. The external device of this application can be used for driving video, Bluetooth function, 3G positioning, wireless Wifi sharing, SOS emergency video storage function and night shooting function.

[0061] However, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of patent protection of the present application. Therefore, all equivalent changes made using the contents of the description or drawings of the present application are also included in the scope of protection of the present application and are hereby stated.
