detailed description

As shown in Figures 1 to 4, an electric vehicle charging pile according to the present invention includes: a base 1, a positioning plate 2, a support frame 3, a charging connector 4 and a distance measuring radar 10; the positioning plate 2 is a center opening The circular plate of the hole, the base 1 is provided with a positioning circular groove matched with the positioning plate 2, the positioning plate 2 is movably installed in the positioning circular groove, and the thickness of the positioning plate 2 is the same as the height of the positioning circular groove.

The ranging radar 10 includes: a processor module 11, a microwave source module 12, a transmitter module 13, a mixer module 14, a receiver module 15, a detector module 16, an alarm module 17 and a power supply module 18, the processing The device module 11 is respectively connected with the above-mentioned microwave source module 12, the mixer module 14 and the alarm module 17 for communication, and the above-mentioned transmitter module 13 is electrically connected with the above-mentioned microwave source module 12 and the mixer module 14 respectively, and the detector module 16 is electrically connected to the receiver module 15, and the power module 18 supplies power for the entire ranging radar 10.

Electromagnetic waves with a wavelength of 1 mm to 1 m are called microwaves. Compared with radio waves, microwaves are characterized by good directional radiation and good transmission characteristics, and are minimally affected by flames, dust, smoke and strong light during transmission. The above-mentioned ranging radar 10 uses pulse radar ranging Principle, the pulse radar signal that is produced by microwave source module 12 is sent to processor module 11, and processor module 11 sends pulse radar signal to automobile through mixer module 14, transmitter module 13, and through detector module 16, receives The device module 15 and the mixer module 14 receive the pulsed radar signal reflected back by the car, which should generate a time difference. According to the time difference, the distance between the vehicle and the charging pile can be judged, thereby reminding the driver to avoid damage to the charging pile due to the driver's misoperation.

The support frame 3 is a hollow rod structure, the charging connector 4 is installed on the top of the support frame 3, one end of the support frame 3 is connected to the central opening of the positioning plate 2, and the return spring 5 and the charging line 6 are installed on the Inside the support frame 3, one end of the return spring 5 is fixed on the top of the support frame 3, and the other end of the return spring 5 passes through the center hole of the positioning plate 2 and is fixed in the center of the above-mentioned positioning circular groove. The charging line 6 One end is connected to the power supply, the other end of the charging cable 6 is connected to the charging connector 4, and the ranging radar (10) is installed in the middle of the support frame (3).

The return spring 5 is a hard tension spring. Back-moving spring 5 can be set to normal state or stretched state, and when bumping above-mentioned support frame 3, support frame 3 can drive locating plate 2 to be fulcrum rotation along a point on the circumference of positioning circular groove, and return-moving spring 5 can appear certain at this moment. Stretched and deformed, after the external force is removed, the return spring 5 will quickly return to its original shape. At this time, it will drive the positioning plate 2 and the support frame 3 to quickly return to the original shape, which greatly avoids damage to the internal equipment in the event of being hit. And because above-mentioned locating disc 2 and locating circular groove all adopt circular structure, no matter from which angle hits boom, whole support frame 3 and locating disc 2 can be pivoted along the point on the circumference of locating circular groove as fulcrum rotation, can not damage base 1 And the internal electrical equipment, and can realize quick return.

On the positioning disc 2 and in the positioning circular groove of the base 1, there are correspondingly arranged magnets 9 of opposite sexes attracting each other. The magnets 9 have three groups, and the three groups of magnets 9 are evenly distributed along the circumferential direction of the positioning disc 2, wherein one group of magnets 9 The polarity settings of the two groups are different from those of the other two groups. For example, the side of the magnet 9 on the positioning disc 2 facing the positioning circular groove in one group is N pole, and the side of the magnet 9 on the positioning circular groove facing the positioning disc 2 is S. pole, while the other two groups of magnets 9 on the positioning disc 2 are S poles on the side facing the positioning circular groove, and the side of the magnet 9 on the positioning circular groove facing the positioning disc 2 is N poles. The stability of the magnet and the principle of repelling each other with the same pole and attracting opposites can make the support frame 3 return to its original position accurately at any angle and after impact with a large displacement.

A reinforcing rib 7 is provided at the joint between the positioning plate 2 and the support frame 3, and the diameter of the positioning plate 2 is slightly smaller than the diameter of the positioning circular groove. Such a design can prevent the positioning plate 2 and the support frame 3 from having sufficient displacement and strength when a huge impact occurs; Pull the support frame back to its position, and rely on the positioning plate and the magnet on the positioning circular groove to achieve accurate positioning without any offset and shaking. The whole device does not need any electronic control equipment to realize automatic reset, which greatly avoids Damage to internal equipment in case of impact.

The base 1 is a circular seat, and the bottom of the base 1 is provided with a fixing pin 8 to facilitate the installation and fixing of the whole device. The cost is low, the maintenance is simple, and the practicability is strong, which can be widely used in any electric vehicle charging pile.
