Abstract

The application discloses a car remote key. The car remote key is characterized in that an upper cover component of a remote control car is disposed on upper surface of an upper cover; a circuit board arranged between the upper cover and a lower cover is powered by a button battery comprising a battery positive electrode and a battery negative electrode ; a protection plate fixed on the lower cover is arranged between the circuit board and the battery; the battery positive electrode contacts a first terminal of a positive shell splinter, a second terminal of which contacts a circuit board positive electrode; the battery negative electrode contacts a first terminal of a negative shell splinter, a second terminal of which contacts a circuit board negative electrode; the first and the second terminals of the positive shell splinter are respectively arranged on both sides of the protection plate; the first and the second terminals of the negative shell splinter are also respectively disposed on both sides of the protection plate. Thus, external material is certainly prevented from damaging the inner part of the key when the battery of the car remote key is being replaced.

Description

technical field [0001] The invention relates to a car remote control key. Background technique [0002] The car remote control key has always been the mainstream of the current car key because of its convenience. Whether it is an active remote control key or a passive remote control key, it will contain a corresponding circuit board and need a matching button battery as a power supply. , so that the key can communicate with the vehicle antenna and controller and transmit and receive signals. Generally, the button battery of the remote control key is not enough to support the transmission of this communication signal within two to three years, so the battery needs to be replaced. Therefore, most of the current remote control key designs adopt a replaceable battery structure. However, when replacing the battery, it is very likely to cause damage to the exposed circuit board, such as water ingress, dust or granular objects entering the key through the battery, affecting the us...
