Problems solved by technology

If the connection between the battery and the charger or the connection between the power supply structure and the battery is not in place, the battery cannot be charged normally, and the power supply structure cannot be powered on and working; and due to the improper connection, the connection between the battery and the charger The contact area between the connector and the structure to be powered and the connector of the battery is too small, which will cause a large amount of heat and burn the connector, causing losses to users

Embodiment 1

[0071] combine Figure 1 to Figure 4 Embodiment 1 of the present invention provides an adapter 40 , which may include a housing 1 , a positive pin 2 , a negative pin 3 , a signal pin 4 and a control circuit 5 . Among them, the positive pole pin 2, the negative pole pin 3 and the signal pin 4 are arranged side by side on the same side of the housing 1, and the positive pole pin 2, the negative pole pin 3 and the signal pin 4 of this embodiment are used to communicate with external devices Simultaneous plug connection. The control circuit 5 is arranged in the housing 1 , and the control circuit 5 is electrically connected to the positive pin 2 , the negative pin 3 and the signal pin 4 respectively.

[0072] In this embodiment, the signal pin 4 includes multiple, see Figure 4 , the plurality of signal pins 4 may include a first signal pin 41 and a second signal pin 42 . Wherein, the first signal pin 41 and the second signal pin 42 are spaced apart, and the length of the first...

Embodiment 2

[0116] With the continuous update of the charger, the charger connector 50 is also constantly updated. The charger connector 50 before the update cannot be adapted to the battery compatible with the updated charger connector, and the interoperability between the products before and after the update is relatively low. Difference. The charger before the update is called the first-generation charger, and the updated charger is called the second-generation charger. The connector 50 of the first-generation charger is different from the connector 50 of the second-generation charger. The first-generation charger can be used for The battery of the first type can be charged but the battery of the second type cannot be charged, the 2 chargers to be charged can charge the battery of the second type but the battery of the first type cannot be charged, the charger of the 1st generation and the charging of the 2nd generation Interoperability between devices is poor.

[0117] In view of thi...

Abstract

The invention discloses an adapter, a charger and an agricultural plant protection machine. The adapter comprises a shell (1), a positive electrode pin (2), a negative electrode pin (3), a plurality of signal pins (4) and a control circuit (5), and the positive electrode pin, the negative electrode pin and the signal pins are arranged at the same side of the shell side by side; the control circuitis arranged in the shell and is electrically connected with the positive contact pin, the negative contact pin and the signal contact pin respectively; the positive electrode pin, the negative electrode pin and the signal pin are used for being simultaneously connected with external equipment in an inserted mode. The plurality of signal pins comprise a first signal pin (41) and a second signal pin (42), the first signal pin and the second signal pin are arranged at an interval, and the length of the first signal pin is smaller than the lengths of the positive electrode pin, the negative electrode pin and other signal pins except the first signal pin; and when the first signal pin detects that the external equipment is in plug connection with the first signal pin, the trigger control circuit controls the adapter to output a power supply so as to supply power to the external equipment or charge the external equipment.

Description

technical field [0001] The invention relates to the field of chargers, in particular to an adapter, a charger and an agricultural plant protection machine. Background technique [0002] When using the charger to charge the battery of the agricultural plant protection machine or use the battery to supply power to the structure (such as motor, flight controller, etc.) The connections between the charger and the battery and between the battery and the structure to be powered are very demanding. When the charger is used to charge the battery, the battery needs to be plugged and connected to the connector of the charger; and when the battery is used to supply power to the structure to be powered, the structure to be powered needs to be plugged and connected to the connector of the battery. If the connection between the battery and the charger or the connection between the power supply structure and the battery is not in place, the battery cannot be charged normally, and the powe...
