[0028] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will provide a detailed description of the technical solutions of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.

[0029] Referring to Figures 1-3 , a specific embodiment of the present utility model provides an automatically powered lamp, including:

[0030] A housing 1;

[0031] A battery control circuit board 7, which is installed in the housing 1 and electrically connected to the main circuit;

[0032] An LED lens module 4, which is installed in the housing 1 and electrically connected to the storage battery;

[0033] A lithium battery 5, which is installed in the housing 1 and electrically connected to the LED lens module 4 through the battery control circuit board 7.

[0034] Existing electric vehicle lamps are directly powered by a storage battery. However, when there is a problem with the main circuit that powers the lamp in the electric vehicle and it cannot supply power to the lamp, the indicator light on the instrument panel will not light up, and the lamp cannot emit light either. When this situation occurs at night, the rider cannot see the road conditions ahead, and the people behind cannot see the vehicle in front clearly, making it very easy to have a traffic accident. In this application, by installing a lithium battery 5 in the housing 1 of the lamp as a backup power source, when the main circuit connecting the lamp in the electric vehicle fails and at the same time the battery control circuit board 7 detects an abnormal main circuit voltage, the lithium battery 5 supplies power to the LED lens module 4 to ensure the normal use of the lamp. Overall, this application can continue to supply power to the lamp when the main circuit fails, facilitating safe driving at night.

[0035] In a further optimized solution, the battery control circuit board 7 includes a circuit board, a control chip installed on the circuit board, a switching tube installed on the circuit board, and a relay.

[0036] The switching tube includes an input end, an output end, and a control end. The input end is connected to the output end of the main circuit, the output end is connected to the electromagnetic coil of the relay, and the control end is connected to the control chip. The switching tube can be a triode or a MOS tube, etc.

[0037] The relay includes a first static contact, a second static contact, and a moving contact. The first static contact is connected to the output end of the main circuit, the second static contact is connected to the output end of the lithium battery 5, and the moving contact is connected to the headlight.

[0038] The control chip can obtain the voltage output by the main circuit. When the voltage is normal (greater than 5V), the control chip outputs a first-level signal to the control terminal of the switching transistor, causing the switching transistor to conduct, so that the electromagnet coil of the relay is energized, generating a magnetic field, and then overcoming the acting force of the spring to attract the moving contact of the relay to the first static contact, that is, the first static contact and the moving contact are conducted, and the main circuit (the battery of the electric vehicle) supplies power to the headlight.

[0039] When the voltage output by the main circuit is abnormal (less than 5V), the control chip outputs a second-level signal to the control terminal of the switching transistor, causing the switching transistor to disconnect, so that the electromagnet coil of the relay loses power, the magnetic field disappears, and then the moving contact of the relay returns to connect with the second static contact due to the elasticity of the spring, that is, the second static contact and the moving contact are conducted, and the lithium battery 5 supplies power to the headlight.

[0040] That is, the battery control circuit board 7 realizes the function of automatically detecting the voltage of the lithium battery 5 and the voltage output by the main circuit.

[0041] Further optimization solutions also include:

[0042] A lamp cover 2, the lamp cover 2 is installed on the housing 1 and is correspondingly arranged with the LED lens module 4.

[0043] Further optimization solutions also include:

[0044] A decorative ring 3, the decorative ring 3 is installed on the housing 1 and is located between the LED lens module 4 and the lamp cover 2.

[0045] Further optimization solutions also include:

[0046] A battery pressure plate 6, the battery pressure plate 6 is installed inside the housing 1, and the lithium battery 5 is installed between the battery pressure plate 6 and the inner wall of the housing 1.

[0047] Further optimization solutions, the LED lens module 4 includes:

[0048] An LED lamp 8, the LED lamp 8 is installed inside the housing 1;

[0049] A lens (not marked in the figure), the lens is installed on the LED lamp 8 and is arranged along the irradiation direction of the LED lamp 8.

[0050] The LED lamp 8 is electrically connected to the lithium battery 5 through the battery control circuit board 7, and the LED lamp 8 is also electrically connected to the storage battery through the battery control circuit board 7.

[0051] Further optimization solutions also include:

[0052] A heat sink 9, the heat sink 9 is installed on the LED lamp 8. It helps the LED lamp 8 dissipate heat and ensures a stable working state.

[0053] Specifically, when the main circuit of the lamp is normal, the lamp is powered by the main circuit. The battery control circuit board 7 is installed inside the lamp and has the function of automatically detecting the voltage of the lithium battery 5 and the output voltage of the main circuit. It is set that when the voltage of the lithium battery 5 is detected to be less than 10V (power shortage), through the battery control circuit board 7, the main circuit automatically charges the lithium battery 5; when the voltage of the lithium battery 5 is detected to be greater than 16V (fully charged), through the battery control circuit board 7, the main circuit automatically stops charging the lithium battery 5.

[0054] When the output voltage of the main circuit is detected to be less than 5V, the lithium battery 5 automatically powers the lamp to make the lamp light up automatically. That is, when a fault occurs in the main circuit of the lamp and it cannot provide enough voltage to light up the lamp, the instrument indicator light will not light up, and the battery control circuit 7 inside the lamp will automatically detect that the main circuit voltage is less than 5V and automatically start the lithium battery 5 inside the lamp to temporarily power the lamp to ensure that the lamp can be normally lit and avoid unnecessary traffic accidents.

[0055] The further optimized solution also includes:

[0056] A manual switch (not shown in the figure), the manual switch is installed on the housing 1, and the manual switch is connected between the input ends of the LED lens module 4 and the battery control circuit board 7. The LED lens module 4 and the battery control circuit board 7 are electrically connected to the lithium battery 5 through the manual switch; after pressing the manual switch once, the LED lens module 4 is electrically connected to the lithium battery 5 through the manual switch.

[0057] The first connection relationship: the LED lens module 4, the battery control circuit board 7, the manual switch and the lithium battery 5 are connected in sequence; that is, the battery control circuit board 7 automatically detects the voltage of the lithium battery 5 and the output voltage of the main circuit;

[0058] The second connection relationship: the LED lens module 4, the manual switch and the lithium battery 5 are connected in sequence. In this state, the LED lens module 4 is connected to the lithium battery 5 through the manual switch and does not pass through the battery control circuit board 7. That is, when the main circuit fails, the LED lens module 4 does not work, and the lithium battery 5 is used to power the LED lens module 4 by operating the manual switch.
