Description

Technical Field

[0001] The utility model belongs to the technical field of charging pile design, in particular to an anti-electric shock charging pile. Background Art

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle charging facilities, are devices that provide electric energy to electric vehicles for charging their batteries. With the popularity of electric vehicles, charging piles have become one of the important infrastructures to promote the development of the electric vehicle market. The construction and operation of charging piles usually require government policy support, grid upgrades, investment and maintenance. With the advancement of technology and the expansion of the market, the popularity of charging piles is increasing, providing necessary support for the widespread adoption of electric vehicles.

[0003] When charging on rainy days, water is easily attached to the charging head, causing leakage, and users are at risk of electric shock. Therefore, there is a need for a charging pile that can operate stably for a long time, has a good drying effect on the charging head and has a low manufacturing cost. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-electric shock charging pile to solve the problems existing in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A charging pile to prevent electric shock comprises a main body device, a drying device is arranged on the top of the main body device, and an air supply device is arranged on the bottom of the drying device; the air supply device comprises a motor, a power gear is arranged on the top of the motor, a receiving gear is arranged in front of the power gear, two driving pulleys are arranged on the top of the receiving gear, a driven pulley is arranged on one side of the driving pulley, a synchronous belt is arranged between the driving pulley and the driven pulley, a fan is arranged on the top of the driven pulley, a driven gear is arranged in front of the receiving gear, and a cam is arranged at the bottom of the driven gear.

[0007] Furthermore: the main device includes a charging base, and a charging head is installed on the top of the charging base.

[0008] Furthermore: the drying device includes an air supply box, a storage box is fixedly arranged on the top of the air supply box, a connecting plate is fixedly arranged on the bottom of the storage box, a plurality of storage racks are arranged in the middle of the storage box, two guide rails are symmetrically fixedly arranged on the bottom of the air supply box, a drying plate is slidably arranged on the guide rails, a pulley is rotatably arranged in the middle of the drying plate, two springs are symmetrically fixedly arranged in front of the drying plate, and a ventilation net is arranged at the bottom of the drying plate.

[0009] Furthermore: the spring is connected to the air supply box by bolts.

[0010] Furthermore: the motor is connected to the air supply box by bolts, the power gear is connected to the air supply box bearing, the fan is connected to the air supply box bearing, and the driven gear is connected to the air supply box bearing.

[0011] Furthermore: the driving pulley is key-connected to the receiving gear.

[0012] Furthermore: the cam is coplanar with the pulley.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The motor drives the power gear to rotate, meshing the receiving gear to rotate, and the receiving gear drives the two active pulleys to rotate, which in turn drives the two driven pulleys to rotate through the synchronous belt, so that the two fans rotate evenly, driving the airflow to enter from the bottom of the air supply box and pass through the connecting plate, blowing away the water on the charging head, drying the charging head and improving the safety of the device. At the same time, the desiccant on the ventilation net filters the water vapor in the airflow to prevent the air from being too humid and the excessive water vapor in the airflow from affecting the drying effect of the charging head;

[0015] 2. When the receiving gear rotates, the synchronous meshing driven gear rotates, and the driven gear drives the cam to rotate. The cam intermittently moves the adjacent pulley, so that the drying plate moves backward along the guide rail, and at the same time, the spring is stretched. When the cam does not drive the pulley to move, the air supply box support spring drives the drying plate to reset through elastic force, so that the drying plate can move back and forth. The design of the cam repeatedly moving the pulley, combined with the spring to drive the drying plate to move quickly back and forth, drives the desiccant on the ventilation net to shake, so as to disperse the damp and condensed desiccant, prevent it from agglomerating and hardening, and affect the drying effect, so as to facilitate the long-term stable operation of the device;

[0016] 3. Through the design that the receiving gear drives the driven gear and the driving pulley to rotate at the same time, a single motor can drive the fan to rotate and drive the drying plate to vibrate at the same time, thereby improving the linkage of the device and saving manufacturing costs.
