[0031] The inventors discovered through research that in current technology, the front compartment of a car is typically used to install the engine, radiator, powertrain mounting structure, and battery. Most family cars use storage batteries, specifically 12-volt low-voltage batteries. This battery, installed inside the front compartment, supplies power to all the vehicle's low-voltage electrical appliances and can store electrical energy while the engine is running. Because the power module is located in the front compartment, while the vehicle's electrical equipment is located in various parts of the interior, the power module needs to be connected to these electrical devices in different locations within the chassis via wires. In the event of a collision, occupants, if conscious, typically choose to escape through the door locks, power windows, sunroof, or trunk lock. However, current technology usually uses electrically controlled door locks. If an accident damages the 12-volt low-voltage battery or the wires break, the door locks, power windows, sunroof, and trunk lock will stop working due to power loss and cannot be opened, hindering occupants' escape from the vehicle.

[0032] To solve the aforementioned technical problems in the prior art, please refer to the following: Figure 1 and Figure 2 This utility model provides an emergency power supply circuit for vehicles and a car.

[0033] like Figure 1 As shown, this utility model provides a vehicle emergency power supply circuit, which includes a power module 1 and several emergency equipment maintenance modules 2. The power module 1 is used to provide electrical energy. The emergency equipment maintenance modules 2 are connected to the power module 1 through wires. The emergency equipment maintenance modules 2 are powered by the electrical energy of the power module 1 and are used to store the electrical energy provided by the power module 1. When the power module 1 and the emergency equipment maintenance modules 2 are disconnected, the emergency equipment maintenance modules 2 maintain the normal operation of the emergency channel through the stored electrical energy.

[0034] Furthermore, please refer to the following: Figure 1 and Figure 2 The emergency equipment maintenance module 2 includes: an energy storage unit, an emergency equipment control unit, and an emergency equipment drive unit; wherein, the energy storage unit is connected to the power module, and the energy storage unit is used to store electrical energy in the power module and provide electrical energy to the emergency equipment control unit when the power module and the energy storage unit are disconnected; the emergency equipment control unit is connected to the energy storage unit, and is used to operate by the electrical energy provided by the power module or the energy storage unit, and output a drive signal to the emergency equipment drive unit; the emergency equipment drive unit is connected to the emergency equipment control unit, and is used to drive the opening of the vehicle emergency passage when receiving the drive signal.

[0035] Specifically, this application uses the left front door of a car, i.e., the first emergency equipment maintenance module 21 of the door, as an example to illustrate the internal structure and working process of the vehicle emergency power supply circuit in this application.

[0036] The emergency equipment drive unit includes a first window regulator and a first door lock drive device. The emergency equipment control unit is a drive circuit for driving the internal motor of the first window regulator and the clutch device in the first door lock drive device. The energy storage unit stores the electrical energy in the power module 1 and provides electrical energy when there is a circuit break between the power module 1 and the energy storage unit. The emergency equipment control unit can operate on electrical energy. When passengers control the corresponding low-voltage electrical appliances, the first emergency equipment control unit can output a drive signal to control the emergency equipment drive unit. The emergency equipment drive unit then drives the low-voltage electrical appliances related to the emergency access channel to operate normally according to the drive signal. The power module 1 can use a 12V low-voltage battery. When the car engine runs to a certain speed, the power module 1 stores the kinetic energy of the car engine converted into electrical energy. The power module 1 serves as an auxiliary power source, supplying power to the starter motor when the engine starts and providing electrical energy to all onboard electrical devices when the car is turned off. The emergency equipment maintenance module 2 is installed at any vehicle-mounted electrical device that can be used for self-rescue in emergency situations. Under normal circumstances, the emergency equipment maintenance module 2 operates and is powered by the electrical energy provided by the power module 1. In an emergency where no external power source is available, the emergency equipment maintenance module 2 maintains its operation using the electrical energy pre-stored internally. Furthermore, since the multiple emergency equipment maintenance modules 2 are each connected to and store electrical energy in the power module 1, the operation of the other emergency equipment maintenance modules 2 will not be affected if any one of them stops working. Passengers can open emergency exits and perform self-rescue through the vehicle-mounted electrical devices controlled by other emergency equipment maintenance modules 2.

[0037] Furthermore, the energy storage unit is located between the emergency equipment control unit and the power module 1. When the power module 1 applies voltage to the energy storage unit, the energy storage unit charges. It discharges to the emergency equipment control unit when the output voltage of the power module 1 is less than a predetermined voltage. The emergency equipment control unit converts the electrical energy output from the energy storage unit into a drive signal for the corresponding emergency equipment drive unit. The emergency equipment drive unit is connected to the emergency equipment control unit and is used to drive and open the emergency passage at the corresponding location in an emergency.

[0038] The emergency equipment drive unit is at least one of a door lock drive device, a window regulator, a sunroof drive device, and a trunk lock drive device. It should be noted that the internal structure of the emergency equipment control unit can be adaptively configured according to the type of equipment and drive method required by the emergency equipment drive unit. For example, if the emergency equipment maintenance module 2 is located at the window and the emergency equipment drive unit includes a window regulator, the emergency equipment control unit converts the electrical energy output from the energy storage unit into a stable and reliable window regulator drive signal to maintain the normal operation of the window regulator, allowing passengers to escape by opening the window. Alternatively, if the emergency equipment maintenance module 2 is located at the door lock and the emergency equipment drive unit includes a door lock drive device, the emergency equipment control unit converts the electrical energy output from the energy storage unit into a stable and reliable door lock drive device drive signal to maintain the normal operation of the door lock drive device, allowing passengers to escape by opening the door. The window regulator drive signal and the door lock drive device drive signal can be controlled by different emergency equipment control units or by the same emergency equipment control unit. Because the emergency equipment control unit and the emergency equipment drive unit are located very close to each other in space, there will be no power transmission failure due to damage to long-distance wires, thus ensuring that passengers can safely escape from the accident vehicle.

[0039] Furthermore, the energy storage unit includes a diode and an energy storage element, wherein the anode of the diode is connected to the power module 1, the cathode of the diode is connected to the emergency equipment control unit, the positive terminal of the energy storage element is connected to the common terminal of the cathode of the diode and the emergency equipment control unit, and the negative terminal of the energy storage element is grounded.

[0040] Specifically, the energy storage element is a supercapacitor with an operating voltage of 16V and a capacitance of 200F. The diode is a Schottky diode, specifically model 30SQ080. In a further embodiment of some preferred embodiments, the maximum forward continuous current of the Schottky diode is 30A, and the reverse surge voltage is 80V. The Schottky diode is used to isolate the 12V low-voltage battery from the supercapacitor, preventing the supercapacitor from reverse discharging to external circuits.

[0041] Furthermore, the plurality of emergency equipment maintenance modules 2, including a first emergency equipment maintenance module 21, a second emergency equipment maintenance module 22, a third emergency equipment maintenance module 23, a fourth emergency equipment maintenance module 24, a fifth emergency equipment maintenance module 25, and a sixth emergency equipment maintenance module 26, are respectively connected to the power module 1. The six emergency equipment maintenance modules 2 can be used to control the four doors, sunroof, and trunk lock, respectively, achieving full coverage of emergency equipment inside the vehicle that can be used to open emergency exits.

[0044] Correspondingly, please refer to the following: Figure 2 This utility model provides a car, including the vehicle emergency power supply circuit as described above; the power module 1 of the vehicle emergency power supply circuit is located in the front compartment of the car, and the emergency equipment maintenance module 2 of the vehicle emergency power supply circuit is located at the car door, window, sunroof or trunk door of the car.

[0045] Specifically, the vehicle emergency power supply circuit may include six emergency equipment maintenance modules 2, which are respectively connected to the power module 1.
