In addition, the guide cover 1028 can also be used as a protective cover of the power receiving protective component 102, so that foreign matters such as water or sediment can be prevented from entering the power receiving protective component 102 or the power receiving seat 101.

Since the charging device 20 is also exposed to the outside air, in order to avoid the charging device 20 from being damaged due to the influence of normal charging caused by the pollution of external impurities or due to the external touch, a protection door is also required to be disposed on the charging device 20, and obviously, the protection door can shield the charging connection position of the charging device 20, and when the power receiving device 10 and the charging device 20 are required to be connected, the protection door can expose the charging connection position of the charging device 20 to realize the connection of the power receiving device 10 and the charging device 20.

Based on this, in order to facilitate the opening of the protection door after the charging device 20 enters the power receiving base 101, the power receiving base 101 is provided with a limiting part 1013, and the limiting part 1013 is used for opening the protection door on the charging device 20 after the charging device 20 pushes up the first power receiving protection door 1021 and the second power receiving protection door 1022 and enters the power receiving cavity 1011.

In some embodiments, referring to fig. 3, 4 and 5, when the protection door of the charging device 20 is a door body rotatably disposed, the limiting portion 1013 may be a limiting protrusion or a protruding edge disposed on an inner wall of the power receiving cavity 1011.

In this way, when the charging device 20 starts to enter the power receiving cavity 1011, the limiting portions 1013 located on the inner walls of two sides of the power receiving cavity 1011 respectively abut against the ends of the two rotating doors on the charging device 20, so that the two rotating doors on the charging device 20 rotate in the direction away from each other, and as the charging device 20 continues to enter the power receiving cavity 1011 along the second direction, the two rotating doors on the charging device 20 rotate to be attached to the limiting portions 1013 on two sides, thereby facilitating the connection of the electrode assembly 1012 in the power receiving device 10 after the charging connection position of the charging device 20 is exposed, and realizing charging.

In some embodiments, referring to fig. 6, 7 and 8, when the protection door of the charging device 20 is a door body in a translational arrangement, the limiting portion 1013 may also be a limiting structure (including but not limited to a limiting block, a limiting protrusion, etc.) disposed at the bottom of the power receiving protection component 102.

The working procedure of the charging device 20 in this embodiment is: when the power receiving device 10 and the charging device 20 need to be connected, the charging device 20 is controlled to move along the direction close to the power receiving device 10, when two translationally arranged door bodies on the charging device 20 are abutted against a limiting structure at the bottom of the power receiving protection assembly 102, the limiting structure triggers the two translationally arranged door bodies to move towards two sides of the charging device 20 respectively, and as the charging device 20 continues to move along the direction close to the power receiving device 10, the two translationally arranged door bodies on the charging device 20 move to an opening position, at the moment, the charging connection position in the charging device 20 is exposed, the charging device 20 is continuously controlled to move towards the power receiving cavity 1011, and the charging connection position in the charging device 20 can be contacted and connected with the electrode assembly 1012, namely, the charging device 20 moves to the charging position.

Of course, according to practical needs, the above-mentioned limiting part 1013 may be replaced by other parts capable of generating driving force to open the two doors on the charging device 20, which is not particularly limited in this embodiment. For example, a magnet or a magnetic block capable of generating magnetic attraction may be disposed at a corresponding position of the power receiving device 10, and correspondingly, a magnetic member matched with the magnet or the magnetic block is disposed in two door bodies on the charging device 20, so that the two door bodies on the charging device 20 can be opened by magnetic attraction matching of the magnetic member and the magnet or the magnetic block, and the charging connection position of the charging device 20 is exposed and then connected with the electrode assembly 1012 in the power receiving device 10, thereby realizing charging.

Of course, the telescopic component 202 may be another component capable of implementing the telescopic function, which is not limited in this embodiment.

In addition, the first rotating plate and the second rotating plate can be movably arranged on the charging seat 201 through elastic pieces, the elastic pieces can be arranged as torsion springs, the torsion springs can be sleeved on the rotating shafts of the pivoting parts, and under the action of the torsion springs, the first rotating plate and the second rotating plate always have a trend of moving towards the closing position. In this way, when the charging electrode 2012 and the electrode assembly 1012 do not need to be connected, the first rotating plate and the second rotating plate are kept at the closed position under the action of the elasticity of the torsion spring, and when the charging electrode 2012 and the electrode assembly 1012 need to be connected, the first rotating plate and the second rotating plate are triggered by the limiting part 1013 on the power receiving seat 101 to move to the open position, so as to realize opening the charging cavity 2011.
