Problems solved by technology
When the remote control key is subjected to the action of conductive liquid (such as liquid water), the conductive liquid will inevitably invade the installation cavity along the gap of the upper shell, thereby affecting the power supply process of the button battery to a certain extent , due to the increase in resistance, the service life of the button battery will drop sharply, and in severe cases, even a battery short circuit will occur, which will lead to the complete failure of the car remote control key function
In addition, the conductive liquid will also cause irreparable erosion damage to the circuit board, which will cause a decrease in control sensitivity

The invention relates to an automobile remote control key, which comprises an upper shell, a circuit board, a button cell, a lower shell, an automobile door locking pressing induction button, an automobile door unlocking pressing induction button, a trunk opening and closing pressing induction button and a flexible sealing piece, wherein the upper shell and the lower shell are buckled with each other to form a mounting cavity; the flexible sealing piece is horizontally arranged in the mounting cavity and divides the mounting cavity into an upper non-sealed mounting sub-cavity and a lower fully-sealed mounting sub-cavity; the circuit board is arranged in the lower fully-sealed mounting sub-cavity; the automobile door locking pressing induction button, the automobile door unlocking pressing induction button and the trunk opening and closing pressing induction button are all arranged over the circuit board and penetrate through the flexible sealing piece till extending into the upper non-sealed installation sub-cavity; and the button cell is electrically connected with the circuit board and is further arranged in the lower fully-sealed mounting sub-cavity. In this way, the influence on normal use of the button cell caused by invasion of external conductive liquid can be effectively prevented, and the phenomenon that the circuit board is eroded is completely eradicated.
Description
technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an automobile remote control key. Background technique [0002] At present, the remote control key has been widely used in automobiles. The remote control key realizes functions such as door locking, door unlocking, and trunk opening and closing by sending wireless signals to the receiving module (such as the body control module). [0003] In the prior art, the car remote key is mainly composed of an upper casing, a lower casing, a circuit board, and a button battery, wherein the upper casing and the lower casing are interlocked to form an installation cavity. Both the circuit board and the button battery for power supply are built in the above-mentioned installation cavity. When the remote control key is subjected to the action of conductive liquid (such as liquid water), the conductive liquid will inevitably invade the installation cavity along the gap of the...
