Document Type and Number:
WIPO Patent Application WO/2021/012301
Kind Code:
A1
Abstract:
A passive remote control key packaging having a signal shielding function, comprising a shielding housing (1) used for accommodating a passive remote control key and an inner wall thereof being a metallic electroplated layer, and a reception antenna (2) being provided on one inner wall of the shielding housing (1). A transmission antenna (4) is provided on an opposite outer wall, a hollow part that is continuous and not on one straight line is provided on the transmission antenna (4), and a portion formed by the hollow portion surrounding the transmission antenna (4) is an elastic piece part (41). A pushing part (5) that slides along the elastic piece part (41) is provided above the transmission antenna (4), and a protruding block (51) that presses on the elastic piece part (41) is provided on the pushing part (5). The pushing part (5) is pushed to move toward or away from a suspended end of the elastic piece part (41), and the protruding block (51) is controlled to press on different positions on the elastic piece part (41), thus changing a degree of deformation of the elastic piece part (41), and thereby a spring contact (3) just exactly makes contact with or is separated from a contact point (21) of the reception antenna (2), implementing connection or cutting off of a signal. Whether to transmit a signal or receive an external signal can be selected, use of the invention is convenient, and information in the key is excellently prevented from being stolen and a car is prevented from being mistakenly unlocked.
