Description

Technical Field

[0001] The utility model relates to the technical field of charging equipment for unmanned guided vehicles, in particular to a connecting device suitable for automatic charging of IGVs and an IGV on-board charger using the connecting device. Background Art

[0002] There will be some errors when various types of unmanned guided transport vehicles enter the charging pile, and there is an urgent need for a reliable charging connection device to connect to the charging gun of the charging pile. Currently, the automated terminal industry has an increasingly high demand for IGV transportation efficiency, and the success rate of IGV automatic charging plays a key role in the efficient operation of the port. The charging gun that comes with the charging pile is a charging arm with a mechanical lock. The IGV has a charging interface for docking with the charging gun. After the IGV to be charged arrives at the charging pile, the charging gun extends and inserts into the charging interface of the IGV to complete the charging. The existing IGV charging interface cannot meet the requirements of use in harsh environments such as the seaside and ports in terms of dust and water resistance, and is prone to water ingress and rust. In addition, due to the accuracy error of the IGV entering the charging pile, tire wear, ground wear or uneven ground, the charging gun and the IGV to be charged cannot maintain a normal charging posture, which may also cause damage to the charging box and charging gun of the IGV to be charged. Currently, there is a circular horn guide for guiding the charging gun, but under the condition of equal width, the circular horn guide has little guiding effect on the charging gun after the four corners are offset, and it is not easy to install detection sensors on the curved outer wall of the circular horn guide, and the structural stability of the circular horn guide is poor; in addition, the protection methods for the IGV charging interface are currently mainly the electric control door method and the dust and water brush method. The former is more cumbersome and costly, while the latter has poor waterproof and dustproof effect and a short lifespan. Utility Model Content

[0034] Example 1

[0035] like Figure 1 、 Figure 2 As shown:

[0036] This embodiment provides a connection device suitable for automatic charging of an IGV, which is applied to the IGV and is used to connect with a charging gun in a pluggable manner. The connection device includes:

[0037] The square speaker guide 1 is used to guide the inserted charging gun; the square speaker guide 1 is horn-shaped as a whole, the small opening 11 of the square speaker guide 1 is close to the charging port of the IGV, and the large opening 12 of the square speaker guide 1 is square;

[0038] The door panel sealing mechanism 2 is provided on the small opening 11 of the square speaker guide 1 and is used to repositionably seal the small opening 11 of the square speaker guide 1 after opening;

[0039] The detection sensor 3 is installed on the outer plane of the square speaker guide 1 and is used to detect whether the charging gun is inserted into the square speaker guide 1.

[0040] Optimally, the square speaker guide 1 is made of plastic; the detection sensor 3 is an electromagnetic induction switch.

[0041] Specifically, the square horn guide 1 increases the fault tolerance of the IGV body automatic charging posture deviation, improves the success rate of automatic charging and the stability during installation and operation, and it is more convenient to install the safety detection sensor on the outer plane of the square horn guide 1.

[0042] Example 2

[0043] Example 2 is a further optimized design of Example 1;

[0044] like Figure 1-Figure 3 As shown:

[0045] The door panel sealing mechanism 2 is installed on the edge of the small opening 11 of the square speaker guide 1.

[0046] Optimally, the door panel sealing mechanism 2 includes at least one closing plate 21 and several elastic reset door hinges 22; the closing plate 21 serves as a closing door plate that can be reset after the small opening 11 of the square speaker guide 1 is opened; a closing plate 21 is equipped with at least one elastic reset door hinge 22, and the elastic reset door hinge 22 serves as an intermediate movable connecting part between the small opening 11 of the square speaker guide 1 and the closing plate 21, and is used to make the closing plate 21 resettable and connected to the edge side of the small opening 11 of the square speaker guide 1 after being elastically opened.

[0047] Optimally, there are two closing plates 21 and two elastic return door hinges 22 ; the closing plates 21 and the elastic return door hinges 22 are connected in a one-to-one correspondence.

[0048] Optimally, the first closing plate serves as the left door panel of the small opening 11 of the square speaker guide 1, and is connected to the left edge of the small opening 11 of the square speaker guide 1 through a first elastic reset door hinge; the second closing plate serves as the right door panel of the small opening 11 of the square speaker guide 1, and is connected to the right edge of the small opening 11 of the square speaker guide 1 through a second elastic reset door hinge.
