The present disclosure relates to the technical field of charging piles, and more particularly, to a gun seat for a charging gun and a charging pile.
With the continuous popularization of new energy vehicles adopting electric energy, such as battery electric vehicles (BEVs) and hybrid electric vehicles (HEVs), charging piles matching with the new energy vehicles also show explosive growth, so as to facilitate charging for the vehicles by users, and ensure the effective endurance of the vehicles. Specifically, when the vehicle needs to be charged, a charging gun on the charging pile is inserted into a charging port of the electric vehicle to achieve charging for the vehicle. After the charging for the vehicle is completed, the charging gun of the charging pile is plugged into a gun inserting seat of the charging pile.
At present, the gun inserting seat of the charging pile generally matches with a gun head of the charging gun in shape and is designed with a corresponding buckling device, and the locking of the gun inserting seat and the charging gun is achieved by the buckling device. However, for the gun inserting seat, in the process of achieving the locking of the charging gun and the gun inserting seat, the user needs to enable the gun head to exactly face the buckling device in the gun inserting seat, and ensure that the gun head is buckled with the buckling device in place, so as to ensure the locking of the charging gun in the gun inserting seat. In this process, the conditions that the charging gun is obliquely inserted and is unable to reset, the buckling is not in place, and the like, are likely to occur, so that the effective locking of the charging gun and the gun inserting seat may not be achieved, which causes the charging gun to fall off the gun inserting seat.
An aspect of the present disclosure aims at providing a gun seat for a charging gun and a charging pile, so as to solve at least the technical problem that it is difficult to buckle a gun inserting seat of the charging pile with the charging gun in the related art.
An aspect of the present disclosure solves the technical problem by adopting the following technical solutions: a gun seat for a charging gun is provided, including: a front housing provided with a first opening through which a gun head of the charging gun enters and exits, and a rear cover fixedly connected to the front housing, wherein the rear cover and the front housing are enclosed to form an accommodating chamber, the accommodating chamber is communicated with the first opening, and the accommodating chamber is configured to limit the gun head after the gun head enters the accommodating chamber from the first opening.
An aspect of the present disclosure solves the technical problem by adopting the following technical solutions: a charging pile is provided, and the charging pile includes the gun seat as described in the above technical solutions; and a charging gun; and a mounting panel, the gun seat being disposed on the mounting panel.

In this embodiment, after completing the charging by using the charging pile 100, the user only needs to place the gun head 22 into the accommodating chamber 102, and then the first stress contact point A, the second stress contact point B, the third stress contact point C and the fourth stress contact point D are respectively generated by the first side plate 120, the second side plate 122, the supporting plate 124 and the top plate 126 with the gun head 22, so that the displacement of the gun head 22 in the accommodating chamber 102 may be automatically limited by matching the four stress contact points together, and self-resetting of the gun head 22 in the accommodating chamber 102 is achieved, while when the user needs to pull the gun head 22 out of the accommodating chamber 102, the gun head 22 may be pulled out of the accommodating chamber 102 by slightly lifting the handle 24 of the charging gun to release the stress contact between the first abutting portion 1200, the second abutting portion 1220, the third abutting portion 1240 and the fourth abutting portion 1260 and the gun head 22.

In some embodiments, a horizontal distance between the first limiting plate and the second limiting plate gradually decreases in a direction of gravity of the charging gun 20, namely, in a vertically downward direction, the horizontal distance between the first limiting plate and the second limiting plate gradually decreases. During a movement process of the gun head 22 in the accommodating chamber 102 in the vertically downward direction under the action of its own gravity, the surfaces of the two sides of the gun head 22 respectively abut the first limiting plate and the second limiting plate to stop the movement, thereby achieving the limiting for the gun head 22 in the left-right direction by the first limiting plate and the second limiting plate.
In some embodiments, the horizontal distance between the first limiting plate and the second limiting plate gradually increases in a horizontal entry direction of the gun head 22 from the first opening 104, namely, in the pull-out direction of the gun head 22, the horizontal distance between the first limiting plate and the second limiting plate gradually decreases, thereby limiting the movement of the gun head 22 towards the pull-out direction of the gun head 22, so that the gun head 22 is more reliably fixed in the accommodating chamber 102.

When the gun head 22 enters the accommodating chamber 102 from the first opening 104, the gun head 22 may be guided to enter the accommodating chamber 102 more conveniently and quickly under the guidance of the first guide surface 1264. The second guide surface 1266 is disposed on one side away from the first opening 104, and after the gun head 22 enters the accommodating chamber 102, one side of the handle 24 of the charging gun rotates downwards under the action of its own gravity, so that one side of the end 228 of gun head rotates upwards, the surface of the top 226 of gun head firstly abuts against the second guide surface 1266, and then as the gun head 22 continues to rotate, the second guide surface 1266 guides the surface of the top 226 of gun head to finally abut against the abutting surface 1262 of the limiting block to generate the fourth stress contact point D.
