Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a driving mechanism and a side bottom charging mechanism. Background Art

[0002] At present, there are two main types of chassis automatic charging according to the connector type: one is contactless automatic charging, mainly represented by wireless charging, which has the following disadvantages:

[0003] The energy transmission efficiency is low because the energy loss caused by the inherent coil heating is very serious and is unavoidable due to the principle.

[0004] The effective charging area is small, and the efficiency is greatly reduced when the charging area is increased. The charging area also depends on the size of the coils at the charging end and the receiving end. The input-output ratio of increasing the charging area brought by increasing the coil is greater than 1.

[0005] There are also defects in safety. The high power of the magnetic field generated during the charging process can liquefy iron objects, which will break through the panel of the charging board and cause accidents such as combustion and discharge. The current detection technology cannot achieve the effect of complete detection, and live detection can only be targeted at large animals, which is very harmful to the product.

[0006] Concerns about electromagnetic radiation: The electromagnetic radiation generated during the charging process is very harmful to the human body. Mild damage can cause hair loss, and severe damage can cause casualties.

[0007] Therefore, although the advantages of wireless charging are obvious, its disadvantages are also unavoidable, and it cannot be used on a large scale at present.

[0008] The other is contact chassis automatic charging, which can be divided into three cases:

[0009] 1. The power receiving end or the vehicle-mounted end is connected downward to the charging end, which is mainly represented by the charging shoe, a method of placing a motion mechanism on the charging car. The main disadvantage is that it increases the weight of the car, reduces the car's endurance, and requires a special ground. The overall cost of the solution is too high.

[0010] 2. The power receiving end or the vehicle-mounted end is docked with the charging end and moves simultaneously for docking. The main advantage of this method is that it simplifies the complexity of the mechanism and increases the range of docking height, but it brings a large increase in cost and cannot produce an increase in power or efficiency, so this method is not suitable for promotion.

[0011] 3. The charging end is connected to the receiving end or the vehicle end upward, and the main representative is the Volterio movement mechanism. However, the docking connector structure is too complicated.

[0012] Therefore, it is necessary to seek a charging device that can adapt to the movement from the ground to the battery charging docking for electric-powered vehicles, so as to complete accurate charging through spatial movement and has a relatively simple structure, can reduce costs, and can be used in a wide range.
