An automotive charging pile

Abstract

The present invention discloses an automobile charging pile, including a charging pile. Two rectangular slots are opened at the bottom near the front side of the charging pile, and the two rectangular slots are symmetrically arranged left and right. A slotted opening is opened near the center of the front side of the charging pile, and the slotted opening is located at the top of the rectangular slot. Through the mutual cooperation among components such as an electric pole, a clamping block, a moving plate, an annular plate, a sleeve, an annular gear, a strip tooth, an opposing plate, a moving block, and a bidirectional lead screw, the present invention can achieve driving the cable joint to move. If the cable joint is stably fixed to the transformer port, the cable joint cannot move upward, and the trigger will not be activated. When the cable joint contacts the trigger located below, several clamping blocks can be activated to re-press and fix the copper wire inside the cable to the cable joint, preventing the cable joint from detaching from the transformer port. When the trigger located above is activated, a buzzer can be activated to remind the user that the current cable joint has seriously detached from the transformer port.

Description

Technical Field

[0002] A charging pile, also known as an electric vehicle charging station or an electric vehicle power supply device, is a device that provides electrical energy for electric vehicles, enabling electric vehicles to store sufficient electrical energy to support their operation. With the popularization of electric vehicles, many families have started to own electric vehicles, so the demand for home charging piles has increased significantly. Such charging piles are generally installed in private garages or parking spaces to provide convenient and safe charging services for electric vehicles.

[0003] When installing the existing home-use automobile charging pile, the cable needs to be first connected to the transformer on the charging pile. For convenient electrical connection, most of the existing cable connectors are round terminal lugs. It is necessary to first wind the copper wire inside the cable around the round terminal lug, and then fit the round terminal lug to the transformer port and fix it with bolts. Although this connection method is relatively convenient, during the use of the charging pile, if it is used for a long time or frequently plugged and unplugged, the terminal may become loose due to wear or fatigue. If not detected and repaired in time, the terminal will fall off. Summary of the Invention

When the cable joint 8 is fixed to the transformer, two cranks 7 can be manually rotated. When the cranks 7 rotate, they can drive the bidirectional lead screw 26 to rotate through the central shaft 28. When the bidirectional lead screw 26 rotates, it can drive two moving blocks 25 to move towards each other, thereby driving the two opposing plates 24 to fix the outer side of the cable 9. When it is necessary to detect the tightness of the cable joint 8, the motor 14 can be started. The motor 14 can drive the upper sheave 5 to rotate through the power output shaft. When the upper sheave 5 rotates, it can drive the lower sheave 5 to rotate through the belt 4. When the lower sheave 5 rotates, it can drive the active winding wheel 16 to rotate through the second rotating shaft. When the active winding wheel 16 rotates, it can drive two rollers 11 to rotate through two first pulling ropes 10. When the two rollers 11 rotate, they can drive the limiting plate 17 to move upward through two second pulling ropes 12. When the two limiting plates 17 move upward, they can drive the sleeve plate 6 to move upward. If the cable joint 8 is completely connected to the transformer, the position of the cable joint 8 is fixed and the trigger 13 is not activated. If the cable joint 8 is loosely connected to the transformer, the sleeve plate 6 drives the cable joint 8 to move upward through the two opposing plates 24 and contacts the lower trigger 13. When the lower trigger 13 is activated, several electric poles 15 can be started. When the electric poles 15 are started, they can push the strip teeth 23 to drive the ring gear 22 to rotate. When the ring gear 22 rotates, it can drive the sleeve 21 to rotate. When the sleeve 21 rotates, it can drive the rotating plate 27 to rotate. When the rotating plate 27 rotates, it can drive several moving plates 19 to move towards each other. The moving plates 19 can re-press the cable 9 and the cable joint 8 through the clamping blocks 18. When the upper trigger 13 is activated, the buzzer can be started to remind the staff.
