Overhead, cable-free and high-load-bearing charging pile and intelligent parking system

Abstract

The invention belongs to the field of intelligent parking, and discloses an overhead, cable-free and high-load-bearing charging pile which comprises a motor and a first lead screw. The system further comprises a first fixing plate, a second fixing plate, a first sleeve, a second sleeve, a third sleeve, a fourth sleeve, a second lead screw and a third lead screw, a motor box is fixed to the first fixing plate, the motor is fixed in the motor box, and the first sleeve, the second sleeve, the third sleeve and the fourth sleeve are electrically connected through conductive parts. One end of each conductive part is connected with the charging interface, the other end of the conductive part is connected with a power supply interface, the charging pile is characterized in that the charging pile is realized based on an electric push rod, the electric push rod has the characteristics of multiple sections capable of synchronously lifting to realize stable pushing of an overweight object (generally greater than 500kg), and meanwhile, the conductive electric push rod is free of a wire and the charging operation of the electric vehicle is realized. The invention further discloses an intelligent parking system.

Description

technical field [0001] The invention relates to the field of intelligent parking, in particular to an overhead, cable-free, high-load charging pile and an intelligent parking system. Background technique [0002] CN201720658761.5 discloses a four-section stroke synchronous lifting electric push rod, which includes a push rod outer cylinder and a motor arranged in the bottom of the outer cylinder. The lower end of the sleeve is movably connected with a first screw seat, a first inner cylinder is provided between the first screw seat and the outer cylinder, the upper end of the sleeve is fixedly connected with a first hollow screw, and the first hollow screw The upper thread is connected with a second hollow screw, and the second hollow screw is connected to the top cover of the push rod through the threaded connection of the outer tube of the top cover. It has a four-section extension stroke, simple and compact design, and can realize simultaneous lifting of four-section str...

Problems solved by technology

[0003] In this case, it realizes the four-section synchronous lifting through the first hollow screw and the second hollow screw, but the problem with this solution is that in the case of high load, the pressure is directly transmitted from the screw to the screw , as the first hollow screw goes deeper into the second hollow screw, its thread contact surface becomes larger and larger, and as the first hollow screw withdraws from the second hollow screw, its thread contact surface becomes smaller and smaller, However, the bearing capacity is certain, which leads to inconsistent pressure on the thread at different positions. The greater the load, the higher the ceiling, the greater the pressure on the thread, which will easily lead to shortened service life.

[0010] This solution uses electric push rods for charging and docking of electric vehicles, but in practical applications, because the charging cables of electric vehicles are very thick, it is unrealistic to use electric push rods to build cables, and the cables cannot be folded inside the electric push rods
