Detailed Description

The following further describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1 to 4, the charging socket for a vehicle according to the present invention includes a housing 2 having a charging port at a front end thereof, and a charging contact is disposed in the housing 2. There is the protective cover plate structure at the externally mounted of casing 2, and the protective cover plate structure will charge the mouth and let out in order to supply the rifle and the socket butt joint that charges when charging, and the protective cover plate structure will charge the mouth and seal when not charging, prevents that granule such as splash, dust or mud piece from getting into, causes the damage to the socket that charges.

The protective cover plate structure is including enclosing ring frame 3 of establishing around casing 2, and ring frame 3 has the part that extends to the mouth the place ahead that charges, and on this part, two slides 31 that extend along upper and lower direction are seted up to the ring frame, and slidable mounting has protective cover plate 5 along upper and lower direction on two slides 31. When the charging gun 1 and the charging socket are plugged for charging, the protective cover plate 5 is controlled to move upwards to open the charging port; when charging is completed and not being charged, the protective cover 5 moves downward, closing the charging port together with the ring frame 3.

The protective cover plate 5 includes a cover plate body 51 corresponding to the charging port, sliders 52 slidably engaged with the slide rail 31 are fixed to both sides of the cover plate body 51, and ends of the two sliders 52 facing away from each other horizontally extend to the outside of the slide rail 31. The upper and lower direction interval arrangement has reset spring 10 and electromagnetism push rod 9 in ring frame 3, and reset spring 10 is by elasticity pressure equipment between ring frame 3 and slider 52 outer end, and the output of electromagnetism push rod 9 is fixed continuous with the outer end of slider 52, and wherein, electromagnetism push rod 9 includes that the lower extreme wears out ring frame 3's push rod 91, and the lower extreme of push rod 91 wears out in the ring frame 3, can increase electromagnetism push rod 9's promotion stroke.

The principle of the electromagnetic push rod is the prior art, and compared with an electric push rod, an electric cylinder and a hydraulic push rod, the electromagnetic push rod adopts the working characteristic of a long-stroke electromagnet, namely the spiral pipe magnetic leakage flux principle, and realizes the linear reciprocating motion of the push rod by utilizing the suction and release (namely the stroke is more than 40 mm-60 mm) of a movable iron core and a static iron core of the electromagnet with the push rod. The electromagnetic push rod has the advantages of crisp and rapid action, less than 0.05 second rise and less than 0.05 second reset. The cycle time is short, and the action frequency can reach more than 3600 times in one hour. The electromagnet adopts the design of power supply and controller conversion, adopts high-power starting and low-power maintaining, and can not only frequently act, but also be electrified for long-term work. Compared with an electric push rod, the electric push rod has no motor or lead screw, and is simple in structure; compared with a hydraulic push rod, the hydraulic push rod has no problem of hydraulic oil leakage and is relatively environment-friendly. The electromagnetic push rod is an ideal action executing mechanism which can realize automatic control and remote control, and compared with an electric push rod, the electromagnetic push rod has the advantages of lower cost and simple and easy control.

The electromagnetic push rod comprises an electromagnetic coil, and after the electromagnetic coil is electrified, the push rod 91 of the electromagnetic push rod moves upwards to compress the return spring 10, so that the protective cover plate 5 moves upwards to open the charging port; after the electromagnetic coil of the electromagnetic push rod is powered off, the protective cover plate 5 is separated from the upward jacking acting force of the electromagnetic push rod, the protective cover plate 5 moves downwards under the action of the reset spring 10, and the charging port of the charging socket is sealed.

In order to achieve the above-mentioned functions and to achieve an automated operation, i.e. without the need for a manual operation of the protective cover to open and close the charging opening. A magnetic proximity switch (not shown) is arranged in the protective cover plate 5, and a magnetic induction sheet (which is arranged in the charging gun 1 and cannot be shown) forming a magnetic mechanism is arranged on the charging gun 1, wherein the magnetic induction sheet can be integrally formed in the charging gun 1 by pouring in a charging gun end cover. Magnetic proximity switches are existing devices that are briefly described below: magnetic proximity switches are one type of proximity switches, one of many in the sensor family, which are made using electromagnetic principles of operation, using advanced processes, and are position sensors, such as: magnetic direct current two-wire type proximity switch. It can convert non-electric quantity or electromagnetic quantity into desired electric signal by means of the change of position relation between sensor and magnetic body so as to attain the goal of control or measurement. The magnetic proximity switch can achieve the maximum detection distance with a small switch volume. It can detect a magnetic object (generally a permanent magnet) and then generate a trigger switch signal output. Furthermore, when a magnetic object moves toward the magnetic proximity switch and approaches a certain distance, the magnetic proximity switch has "sense", and the switch is actuated, usually called "detection distance". Different types of magnetic proximity switches also have different detection distances.

Then, when the charging gun 1 approaches the charging socket, the magnetic proximity switch is sensed by the magnetic sensing sheet in the charging gun 1, and the switch state changes, generally from off to on. In addition, since the magnetic field can pass through many non-magnetic objects, the magnetic objects do not necessarily need to be directly close to the sensing surface of the magnetic proximity switch, that is, the arrangement mode of the magnetic proximity switch is not unique, as long as the magnetic signal can be transmitted to the magnetic proximity switch. In addition, the magnetic signal can be transmitted to the magnetic proximity switch through a high temperature to generate a trigger action.

In this embodiment, the relay has been arranged in series on electromagnetic push rod's solenoid supply circuit, the relay is normally open type relay, and simultaneously, control links to each other between magnetic proximity switch and the relay, when rifle 1 that charges is close to the socket that charges to certain distance, magnetic proximity switch on the protective cover plate senses the magnetic mechanism in the rifle that charges after, signal messenger relay combined floodgate to the relay, electromagnetic push rod's solenoid is electrified, electromagnetic push rod's output upwards promotes the protective cover board and removes, compression reset spring, open the back completely, electromagnetic push rod continues the application of force and keeps the protective cover board in the position of opening.

A delay power-off switch is arranged in series on a power supply circuit of an electromagnetic coil in the electromagnetic push rod, wherein the delay power-off switch is a normally-closed switch. When the delayed power-off switch is triggered, the delayed power-off switch can be switched off after a set time (such as 5 s) of delay. When the spring reset normally open position switch 8 rebounds from the closed state to the open state, the delay power-off switch can be controlled to be switched off. When the charging gun 1 and the shell 2 move relatively to charge, the delay power-off switch is in a closed state, the relay is in an open state, the spring reset normally-open position switch 8 is in an open state, and when the charging gun 1 is close to the shell 2, the relay is closed (the principle and the process are shown in the specification), so that a power supply circuit of the electromagnetic coil is conducted, then the mechanical lock catch end 11 of the electronic lock presses the spring reset normally-open position switch 8 to enable the spring reset normally-open position switch 8 not to be in the closed state, and the delay power-off switch is kept in the closed state; after the completion of charging, outwards extract charging gun 1, charging gun 1's electronic lock machinery hasp end 11 breaks away from the pressing of normally opening position switch 8 to spring return, spring return normally opens position switch 8 and becomes the off-state by the closure state, control time delay power off switch disconnection after certain time (as 5 s) of delay for the supply circuit disconnection, solenoid loses the electricity, and protective cover plate 5 removes downwards under reset spring 10's elasticity restoring force effect, seals the mouth that charges. During the time delay, the charging gun 1 can be pulled out.
