Plug inlet for storing electrical vehicle plug

Abstract

A method includes plugging a plug into a socket, wherein the plugging includes pushing the plug into the socket at least up to a point that a latch clicks into the plug and locks the plug in place. Pressing down on a lever that rotates around an axis causes the lever to be pushed down. This results in the latch moving away from the plug and unlocking the plug from the socket, to thereby allow the plug to be separated from the socket.

The torsion spring may be designed to position lever 105, for example, when no torque is applied to the torsion spring, in a locked position (as shown), meaning that latch 108 is positioned fully or partially in mortise 107. Torque may be applied to the torsion spring by turning lever 105 around axis 109 towards divider 106, and latch 108 may be partially or fully taken out of mortise 107, unlocking click-in lock 103.

(16) According to some aspects, click-in lock 103a may have a first magnet 110, mounted on lever 105, and a second magnet 111, mounted on divider 106. Magnets 110 and 111 may be magnetized in polarizations configured to reject each other. Click-in lock 103a may be designed to be normally locked because of the rejection force between magnets 110 and 111, and lever 105 may be positioned away from divider and latch 108 may be positioned fully or partially in mortise 107 (as shown). Force may be applied to lever 105 rotating lever 105 around axis 109 towards divider 106 and latch 108 partially or fully out of mortise 107.

(17) According to some aspects, one of magnets 110 and 111 may be replaced with a rejecting material such as a metal, configured to reject an opposing magnet. For example, magnet 110 may be replaced with a metal plate configured to reject and be rejected from and by magnet 111. Magnet 111 may be designed to be of a polarity to reject magnet 110 or a metal plate.

(18) According to some aspects, magnets 110 and/or 111 may be electromagnets. An electromagnet may be designed to be magnetized when receiving an electric current higher than a certain threshold, and demagnetized when receiving a current under a certain threshold. According to an aspect of the disclosure, where click-in lock 103a is designed using electromagnets for magnets 110 and/or 111, a plug may be designed to be locked when an electric current over a certain threshold is applied to electromagnets 110 and 111, and unlocked when the electric current is under a certain threshold. Plug inlet 100 may include a switch designed to apply or cease a current configured to magnetize or demagnetize electromagnets 110 and 111. The switch may be a mechanical switch (such as a button, a flip-switch etc.), and may be an electrical switch, such as an RFID (radio frequency identification) key, fingerprint key, a keypad key, etc. According to some aspects, plug inlet 100 may include magnets 110 and 111 designed to hold click-in lock 103 in a locked position configured to be unlocked and locked depending on a force applied to click-in lock 103a, and may include one or more electromagnets designed to hold click-in lock 103a in a locked position preventing the change of position of click-in lock 103a when the electromagnets are magnetically coupled.

Click-in lock 103b may include magnets 110a and 111a, designed to attract each other. Magnet 111a may be mounted on latch 108, and magnet 110a may be mounted on divider 106, designed to be in proximity to magnet 111a when latch 108 is positioned in mortise 107. A magnetic force may be applied between magnets 111a and 110a, so that click-in lock may be normally closed. In order to separate magnets 110a and 111a, a mechanical force may be applied to lever 105. For example, a finger may actuate that lever 105 by pressing down on the lever 105 thereby applying enough force to separate between magnets 110a and 111a. According to some aspects, magnet 110a or magnet 111a may be replaced with a metalized area that may be magnetically drawn to magnet 111a or magnet 110a.

(20) According to some aspects, plug inlet 100 may include a magnetic sensor (not shown) configured to sense a plug designed to plug into plug inlet 100. The magnetic sensor may sense a magnet mounted in and/or on a designated plug. The magnetic sensing may include sensing an angle of the plug in relation to plug inlet 100, the distance of the plug from plug inlet 100, sensing a level of connection between a corresponding plug and plug inlet 100. Sensing a level of connection may include, for example, determining whether or not the plug and plug inlet 100 clicked-in to each other, whether the plug and the plug inlet are touching but not clicked-in, or if the plug and plug inlet are not touching.

(21) Reference is now made to FIG. 2, which illustrates a plug inlet 200 including a socket 202 and a plurality of click-in locks 203a-203b. Plug inlet 200 may be designed to house a plug in socket 202, such as plug inlet 100 of FIG. 1A, and may be configured to lock a corresponding plug to plug inlet 200 by click-in locks 203a and 203b. Click-in locks 203a-203b may be positioned above, below and/or to a side of socket 202.
