The positive and negative chucks are respectively sandwiched between the positive and negative electrodes of the battery. Have the same effect. Further, referring to FIG. 1, the other end of the positive electrode connector 32 forms another positive chuck 321 , and the other end of the negative electrode connector 33 also forms another negative chuck 331. Please refer to FIG. 1 and FIG. The correct connection of the invention is to clamp the positive chuck 321 The positive electrode of the vehicle battery 2 is provided, and the negative electrode chuck 331 is interposed between the negative electrode of the vehicle battery 2. When the present invention is intended to provide emergency power to a 12V vehicle battery, the voltage of the battery 31 is also 12V.

The switch 4 and the rescue module are electrically connected in series, and the switch 4 is used to open and close the rescue module. More specifically, the switch 4 is disposed on the positive connector 32, and the switch 4 is electrically connected in series with the battery 31. In this embodiment, the switch 4 is disposed in a casing 6, the casing 6 is disposed on the positive pole connecting member 32, the casing 6 includes a knob 61 and a hole 62, and the knob 61 is used to open and close the switch 4, and thereby The control switch 4 opens and closes the rescue module. In other embodiments, the knob 61 can also be replaced by a button to open and close the switch 4.

In the present embodiment, the warning device 5 is disposed on the positive electrode connector 32. More specifically, the warning device 5 is disposed in the housing 6, and the warning device 5 and the switch 4 are electrically connected in parallel. Referring to FIG. 2 and FIG. 3, the positive terminal of the warning device 5 is electrically connected to the positive electrode of the battery 31, whereby the polarity connection between the warning device 5 and the battery 31 is correct. In another embodiment, the switch 4 and the warning device 5 can also be disposed on the negative connection member 33, and are also connected in parallel. However, the negative end of the warning device 5 at this time is electrically connected to the battery 31. The negative electrode, whereby the polarity of the warning device 5 and the battery 31 is connected correctly. The voltage of the warning device 5 is between 3V and 30V. The warning device 5 may be a buzzer, a light emitting diode or a combination of the two. Of course, the warning device 5 may also be other components that can emit sound or light.

Referring to FIG. 1 and FIG. 2, when the user correctly connects the present invention to the vehicle battery 2, the positive electrode holder 321 of the other end of the positive electrode connector 32 is provided with the vehicle battery 2 The positive electrode, the negative electrode chuck 331 at the other end of the negative electrode connector 33 is interposed on the negative electrode of the vehicle battery 2, and before the switch 4 is turned on, the battery 31, the switch 4, and the vehicle battery 2 are in an open state, and cannot be formed. In the conduction circuit, the battery 31 does not provide emergency power to the vehicle battery 2, but at this time, the positive terminal of the warning device 5 is electrically connected to the positive pole of the battery 31, and the negative terminal of the warning device 5 is electrically connected to the battery for the vehicle 2. The positive electrode, therefore, the vehicle battery 2 and the battery 31 simultaneously input a positive voltage to the warning device 5, whereby the warning device 5 cannot be activated. In another embodiment (not shown), since the switch 4 and the warning device 5 are disposed on the negative connection member 33, the negative end of the warning device 5 is electrically connected to the negative pole of the battery 31, and the positive of the warning device 5 The terminal is electrically connected to the negative pole of the vehicle battery 2, so that the vehicle battery 2 and the battery 31 simultaneously input a negative voltage to the warning device 5, whereby the warning device 5 cannot be activated. Then, after the switch 4 is turned on, the battery 31, the switch 4, and the vehicle battery 2 form a conduction circuit. At this time, the battery 31 can supply emergency power to the vehicle battery 2.

Referring to FIG. 3, if the user inadvertently clamps the positive electrode tab 321 of the other end of the positive electrode connector 32 to the negative electrode of the vehicle battery 2, and the negative electrode chuck 331 of the other end of the negative electrode connector 33 is clamped to the vehicle. The positive electrode of the battery 2 is, in short, electrically connected to the negative electrode of the battery battery 2, and the negative electrode of the battery 31 is electrically connected to the positive electrode of the vehicle battery 2, such that the connection is called "pole". If the switch 4 is turned on when the polarity is reversed, a large current will be generated instantaneously, causing damage to the battery 31 or the vehicle battery 2. In this embodiment, before the "polarity reversal" occurs and the switch 4 has not been turned on, the battery 31 and the vehicle battery 2 are connected in series to form a loop having a total voltage of 24V, which is equal to the misconnection (pole). Sexual reversal) The next two batteries (one for battery 31 and the other for vehicle battery 2) are connected in series to form a circuit with a total voltage of 24V, and the negative terminal of the warning device 5 is electrically connected to the negative pole of the vehicle battery 2, and the vehicle is used at this time. The battery 2 inputs a negative voltage of 24V to the warning device 5, and the battery 31 inputs a positive voltage of 24V to the warning device 5, and the warning device 5 is turned on. In another embodiment (not shown), since the switch 4 and the warning device 5 are disposed on the negative electrode connector, the positive terminal of the warning device 5 at this time is electrically connected to the positive electrode of the vehicle battery 2, so that the vehicle is used. The battery 2 inputs a positive voltage of 24V to the warning device 5, and the battery 31 inputs a negative voltage of 24V to the warning device 5, that is, the positive and negative voltages are input in the opposite manner to the foregoing embodiment, but The warning device 5 will still be activated as well. Further, because of this misconnection method, a circuit with a total voltage of 24V is formed, and the warning device 5 can be activated and an alarm signal is issued, which is the sound of the buzzer or the light-emitting diode. The light, the warning signal can be spread out through the hole 62 of the casing (as shown in FIG. 1), and thereby alerting the user to "polarity reverse", the switch 4 cannot be turned on, and immediately The problem of "polarity reversal" can be eliminated by connecting the battery 31 and the vehicle battery 2 in the correct manner.

Therefore, the vehicle emergency rescue device disclosed in the present invention mainly uses a warning device and the switch to be electrically connected in parallel, and the positive terminal of the warning device is electrically connected to one of the positive pole of the battery and the positive pole of the vehicle battery. The negative end of the warning device is electrically connected to one of the negative pole of the battery and the negative pole of the vehicle battery, and the problem that the polarity is reversed can be known immediately after the switch is turned on, whether the warning device is activated or not. The user quickly eliminates the problem of "polarity reversal" and can protect the electricity Pool or car batteries are not destroyed by excessive transient currents. More importantly, the present invention achieves the effect of preventing polarity reversal without excessive components, and furthermore has the advantages of simple structure, small size, and low cost.
