It should be noted that the components depicted in the accompanying drawings are not necessarily shown to scale; and the same or similar components will be given the same or similar reference numerals or similar technical terms.

[0062] Reference Figure 1 This application proposes a power supply control circuit 100 for use in a vehicle 10. The vehicle 10 includes a control module 200 and an electrical device 300. The control module 200 is configured to output an operating signal, which is used to drive the electrical device 300 to operate. The power supply control circuit 100 includes a lamp 110 and a switch circuit 120. A first terminal of the switch circuit 120 is configured to receive a vehicle power supply voltage, a second terminal of the switch circuit 120 is electrically connected to the lamp 110, and a third terminal of the switch circuit 120 is electrically connected to the control module 200. The operating signal is also configured to control the switching on / off of the first and second terminals of the switch circuit 120.

[0063] The vehicle 10 may be an electric vehicle or a hybrid vehicle. The control module 200 may be a body controller. The lamp 110 may be a lamp 110 installed according to user needs. For example, a camping lamp 111, an auxiliary high beam lamp 112, an ambient light, a width lamp, a ground lamp, a tire light, a daytime running light, a turn signal lamp, etc. Since the installed lamp 110 does not belong to the functional lamp 110 of the entire vehicle, the original equipment of the vehicle 10 may limit the start time of the installed lamp 110. For example, the installed lamp 110 is not allowed to start when some equipment is running, or the installed lamp 110 is allowed to start only when some equipment is running.

[0064] In this embodiment, the control module 200 can output an operating signal to control the operation of the electric device 300. The first and second terminals of the switch circuit 120 can be connected / disconnected under the control of the operating signal. In this way, when the electric device 300 is in operation, it can connect / disconnect the path between the vehicle power supply voltage and the lamp 110, thereby controlling the power on / off of the lamp 110.

[0065] For example, when the electrical device 300 is operating, the lamp 110 is not allowed to start. The first and second terminals of the switch circuit 120 can be configured to disconnect upon receiving an operating signal, thereby disconnecting the path between the vehicle power supply voltage and the lamp 110, thereby controlling the lamp 110 to be powered off and ensuring that the lamp 110 does not start when the electrical device 300 is operating. When the electrical device 300 is not operating, that is, when the switch circuit 120 does not receive an operating signal, the switch circuit 120 can control the first and second terminals to connect, thereby controlling the lamp 110 to be powered on, allowing the lamp 110 to start even when the first device is not operating.

[0066] Alternatively, the lamp 110 is allowed to start only when the electrical device 300 is operating. The switch circuit 120 can be configured to connect the first and second terminals upon receiving an operating signal, thereby disconnecting the path between the vehicle power supply voltage and the lamp 110, thereby controlling the lamp 110 to power on and enable the lamp 110 to start when the electrical device 300 is operating. When the electrical device 300 is not operating, that is, when the switch circuit 120 does not receive an operating signal, the switch circuit 120 can disconnect the first and second terminals, thereby controlling the lamp 110 to power off, ensuring that the lamp 110 does not start when the electrical device 300 is not operating.

[0067] In one embodiment, the lamp 110 may be provided with a switch for turning on / off the lamp 110. After the lamp 110 is powered on, the user may control the lamp 110 to turn on / off by turning on the switch on the lamp 110.

[0068] The present application controls the first and second ends of the switch circuit 120 to be turned on / off through the working signal output by the control module 200, thereby controlling the power on / off of the lamp 110, so that the lamp 110 is in a state where it can be started / cannot be started when the electrical equipment 300 is running, thereby meeting the use requirements of the additional lamp 110 and does not require modification of the controller software and hardware.

[0069] Reference Figure 2 In one embodiment, the switch circuit 120 includes a first switch circuit 121 and a second switch circuit 122. The first end of the first switch circuit 121 is used to connect to the vehicle power supply voltage, the second end of the first switch circuit 121 is electrically connected to the first end of the second switch circuit 122, and the third end of the first switch circuit 121 is electrically connected to the control module 200; the second end of the second switch circuit 122 is electrically connected to the lamp 110. The working signal is used to control the connection / disconnection between the first and second ends of the first switch circuit 121. The second switch circuit 122 is configured to be connected / disconnected when triggered.

[0070] In this embodiment, the first and second terminals of the first switch circuit 121 can be turned on and off by a working signal, and the second switch circuit 122 can be turned on and off by a user trigger. Through the combined control of the first and second switch circuits 121, 122, the lamp 110 can be turned on and off by the user in compliance with relevant regulations.

[0071] For example, when the electrical device 300 is running, the lamp 110 is not allowed to start. The first end and the second end of the first switch circuit 121 can be set to be disconnected when receiving a working signal, thereby disconnecting the path between the vehicle power supply voltage and the lamp 110, and then controlling the lamp 110 to be powered off, ensuring that the lamp 110 will not start when the electrical device 300 is running. When the electrical device 300 is not running, that is, when the first switch circuit 121 does not receive a working signal, the first switch circuit 121 can control the first end and the second end to be connected, so that the vehicle power supply voltage is connected to the second switch circuit 122. When the user needs to light up the lamp 110, the second switch circuit 122 is triggered to be turned on, and the lamp 110 can be controlled to be powered on and started. When the user needs to turn off the lamp 110, the second switch circuit 122 is triggered to be turned off again, and the lamp 110 can be controlled to be powered off and turned off.

[0072] Or the lamp 110 is allowed to start only when the electrical device 300 is running. The first end and the second end of the first switch circuit 121 can be set to be connected when a working signal is received, and the vehicle power supply voltage is connected to the second switch circuit 122. When the user needs to light the lamp 110, the second switch circuit 122 is triggered to be turned on, and the lamp 110 can be controlled to power on and start. When the user needs to turn off the lamp 110, the second switch circuit 122 is triggered to be turned off again, and the lamp 110 can be controlled to be powered off and turned off. When the electrical device 300 is not running, that is, when the first switch circuit 121 does not receive a working signal, the first switch circuit 121 can control the first end and the second end to be disconnected, thereby disconnecting the path between the vehicle power supply voltage and the lamp 110, and then controlling the lamp 110 to be powered off, ensuring that the lamp 110 will not start when the electrical device 300 is not running.

[0073] The first switch circuit 121 can be implemented by a relay, a thyristor, a MOS tube, etc. The second switch circuit 122 can be implemented by a key switch, a knob switch, etc., or set as a soft switch on a touch screen.

[0074] Reference Figure 3In one embodiment, the first switch circuit 121 includes a first switch component Q1. A first end of the first switch component Q1 is used to connect to the vehicle power supply voltage, a second end of the first switch component Q1 is electrically connected to a first end of the second switch circuit 122, and a third end of the first switch component Q1 is electrically connected to the control module 200. The operating signal is used to control the first switch component Q1 to be turned on / off.

[0075] In this embodiment, the first switch component Q1 can be implemented using a relay. For example, a normally closed relay can be used, which is disconnected when receiving an operating signal and connected when not receiving an operating signal. Alternatively, a normally open relay can be used, which is connected when receiving an operating signal and disconnected when not receiving an operating signal.

[0076] Reference Figure 4 In one embodiment, the first switch circuit 121 further includes a second switch component Q2. A first end of the second switch component Q2 is used to connect to a supply voltage, a second end of the second switch component Q2 is electrically connected to the first switch component Q1 and the power-consuming device 300, respectively, and a third end of the second switch component Q2 is electrically connected to the control module 200. The first and second ends of the second switch component Q2 are configured to be turned on based on the control of the operating signal and to output a drive signal for driving the power-consuming device 300. The first drive signal is also configured to control the on / off switching of the first switch component Q1.

[0077] In this embodiment, the second switch circuit 122 can be implemented using a relay. For example, upon receiving an operating signal from the control module 200, the relay closes, transmitting the voltage at the power supply end to the power-consuming device 300 and the first switch component Q1, respectively. This achieves electrical isolation and improves the safety of the power supply control circuit 100.

[0078] Reference Figure 5 In one embodiment, the lamp 110 includes a camping lamp 111, and the electrical device 300 includes a driving component 310. The working signal is used to control the first end and the second end of the switch circuit 120 to be disconnected.

[0079] In this embodiment, the control module 200 may be a body controller, and the drive assembly 310 may be a drive motor for driving the vehicle 10. When the vehicle 10 is running, the body controller outputs a working signal to control the drive assembly 310 to drive the vehicle 10.

[0080] Some users may wish to install a camping light 111. While camping, the camping light 111 can draw power from the vehicle 10 to illuminate the campsite. However, the camping light 111 is generally not permitted to be activated while the vehicle 10 is in operation. Therefore, when the switch circuit 120 receives an operating signal, indicating that the vehicle 10 is in operation, the first and second ends of the switch circuit 120 are disconnected, ensuring that the lamp 110 cannot be activated. When the switch circuit 120 does not receive an operating signal, indicating that the vehicle 10 is not in operation, the first and second ends of the switch circuit 120 are connected, allowing the camping light 111 to be turned on. This allows users to turn the camping light 111 on and off as needed.

[0081] Reference Figure 6 In one embodiment, the lamp 110 includes an auxiliary high beam lamp 112, and the electrical device 300 includes a high beam lamp 320. The working signal is used to control the first terminal and the second terminal of the switch circuit 120 to be connected.

[0082] In this embodiment, the vehicle body controller can output an operating signal to control the activation of the high beam 320. In remote areas without streetlights, the brightness of the vehicle 10's original high beam 320 may not be sufficient. Some users frequently drive the vehicle 10 in such environments and wish to install auxiliary high beams 112 to improve driving safety. However, the auxiliary high beam 112 can generally only be activated when the high beam 320 is on. Therefore, when the switch circuit 120 receives an operating signal, indicating that the high beam 320 is on, the first and second terminals of the switch circuit 120 are connected, activating the auxiliary high beam 112. When the switch circuit 120 does not receive an operating signal, indicating that the high beam 320 is not on, the first and second terminals of the switch circuit 120 are disconnected, ensuring that the auxiliary high beam 112 is not activated. This allows the user to activate / deactivate the auxiliary high beam 112 as needed.

[0083] Reference Figure 7 In one embodiment, the switch circuit 120 includes a third switch circuit 123 and a fourth switch circuit 124. A first end of the third switch circuit 123 is used to connect to the vehicle power supply voltage, a second end of the third switch circuit 123 is electrically connected to the lamp 110, and a third end of the third switch circuit 123 is electrically connected to a first end of the fourth switch circuit 124. A second end of the fourth switch circuit 124 is electrically connected to the control module 200. The fourth switch circuit 124 is configured to be turned on / off when triggered, and the operating signal is used to control the turning on / off of the first and second ends of the third switch circuit 123.

[0084] In this embodiment, the third switch circuit 123 can be implemented by a relay, a MOS tube, a thyristor, etc. The fourth switch circuit 124 can be implemented by a key switch, a knob switch, etc., or can be set as a soft switch on a touch screen.

[0085] The control module 200 can output an operating signal to control the operation of the electrical device 300. At the same time, the operating signal is connected to the second end of the fourth switch circuit 124. When the lamp 110 needs to be illuminated, the user triggers the fourth switch to turn on, transmitting the operating signal to the third end of the third switch circuit 123, thereby controlling the first and second ends of the third switch circuit 123 to be connected, and the lamp 110 is powered on and illuminated. When the lamp 110 needs to be extinguished, the user triggers the fourth switch circuit 124 to turn off again. No operating signal is connected to the third end of the third switch circuit 123, the first and second ends of the third switch circuit 123 are disconnected, and the lamp 110 is powered off and extinguished. The lamp 110 may include an auxiliary high beam 112, and the electrical device 300 may include a high beam 320.

[0086] Reference Figure 8 In one embodiment, the lamp 110 is disposed outside the vehicle 10, and the power supply control circuit 100 further includes a conductive wire 130. The lamp 110 is disposed outside the vehicle 10, and the vehicle 10 is provided with a through hole 400 for the conductive wire 130 to pass through. The conductive wire 130 is used to connect the lamp 110 and the switch circuit 120.

[0087] In this embodiment, the lamp 110 mounted on the outside of the vehicle 10 can be connected to the switch circuit 120 inside the vehicle 10 via a conductive wire 130. A through hole is provided near the lamp 110 on the vehicle 10, through which the conductive wire 130 passes, thereby achieving the connection between the lamp 110 and the switch circuit 120.

[0088] In one embodiment, the vehicle 10 further includes a waterproof plug 500. The waterproof plug 500 is used to seal the through hole 400. When the lamp 110 is not required, the waterproof plug 500 can be used to block the through hole 400. This allows the user to install the lamp 110 without affecting the normal use of the vehicle 10.

[0089] Reference Figure 1 and Figure 8 The present application also provides a vehicle 10, comprising the aforementioned power supply control circuit 100. The vehicle 10 may be an electric vehicle or a hybrid vehicle. The power supply control circuit 100 may be configured as one or more circuits depending on the number of electrical devices 300.

[0090] The detailed structure of the power supply control circuit 100 can be referred to the above-mentioned embodiment and will not be repeated here. It can be understood that since the above-mentioned power supply control circuit 100 is used in the vehicle 10 of the present application, the embodiment of the vehicle 10 of the present application includes all technical solutions of all embodiments of the above-mentioned power supply control circuit 100, and the technical effects achieved are also exactly the same, which will not be repeated here.

[0091] The specific embodiments of the present application have been described above with reference to the accompanying drawings. However, those skilled in the art will appreciate that various modifications and substitutions may be made to the specific embodiments of the present application without departing from the spirit and scope of the present application.
