Abstract

The utility model relates to the field of automatic storage systems, in particular to an automatic charging end of a telescopic shuttle vehicle; the method is characterized in that: including inside hollow box casing, the tail end in the box casing sets up the battery, sets up trigger mechanism in the head segment in the box casing, trigger mechanism is including two contacts that are used for the intercommunication circuit, and one of them contact stretches out from the top of box casing, and another contact is in the box casing and contact with the battery under the contact that stretches out at the top receives pressure to constitute the charging circuit. The height of the whole mechanism of the charging module in a contact retraction state is greatly reduced, and meanwhile, contact of the contacts is elastic, so that the contacts can be reliably contacted even if friction loss occurs; because the contacts retract when not charging, the vehicle does not touch the contacts during normal operation, various risks can be reduced, and storage automation is improved.

Description

Telescopic shuttle automatic charging end

Technical Field

The utility model relates to an automatic change storage system field, specifically be an automatic end that charges of telescopic shuttle.

Background

In the systems, the secondary vehicle and the shuttle vehicle are both powered by batteries, the use of the batteries means that frequent charging is required, and the charging usually has two modes of online charging and offline charging. While it is clear that the online charging mode theoretically has a higher operating efficiency. The working mode of the on-line charging module on the current market is that a charging module is arranged at a certain fixed position in a roadway, when the system judges that the shuttle vehicle needs to be charged, the shuttle vehicle automatically runs to the position, then is electrified for charging, and the vehicle enters a working system after the charging is finished. The fixed contact that common contact design becomes spring coupling stands in the tunnel always, and the advantage of doing so is very obvious, and is frivolous, and occupation height space is little, low in manufacturing cost is fit for in the intensive storage system of automation in very narrow and small space. But the disadvantages are also evident: a. charging is usually carried out at a fixed position of a certain roadway opening, the roadway is usually used for putting goods, and a contact under a vehicle and a fixed contact of the roadway opening are rubbed when the vehicle carries the goods in and out each time, so that loss is generated after a long time, and the charging effect is unstable. b. Each friction has the hidden danger of spark discharge and fire hazard. c. Because the bottom of the contact block is connected by the spring, the vehicle can touch the contact block every time the vehicle passes back and forth, and the contact block can be damaged. d. If the positive electrode and the negative electrode are in contact with the vehicle body, a short circuit can be generated, and the consequence is very serious. In order to avoid these problems, many attempts have been made, such as cylinder pushing, stepping motor driving, etc., electromagnets, etc., the former requiring a complicated structure and a gas supply, the latter requiring a motor and a driver, the latter requiring too little pushing force and too high installation, and being unable to solve the problems of volume and size, high cost, uncontrollable space height, and inability to be used in dense storage systems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned defect, provide a compact structure, safe and reliable's telescopic shuttle automatic charging end.

In order to achieve the above object, the present invention is realized as follows:

the utility model provides a telescopic shuttle car automatic charging end, includes inside hollow box casing, sets up the battery at the tail end in the box casing, sets up trigger mechanism in the head segment in the box casing, trigger mechanism is including two contacts that are used for the intercommunication circuit, and one of them contact stretches out from the top of box casing, and another contact is in the box casing and contact with the battery under the condition that the contact that stretches out at the top received pressure to constitute the charging circuit.

The trigger mechanism of the telescopic shuttle automatic charging end comprises a telescopic contact block, a movable wedge-shaped block, a fixed shaft, an extension spring, a pulley and an electric push rod; the middle part of the telescopic contact block is rotatably arranged in the box-type shell through a fixed shaft, the top of the telescopic contact block extends out of the top of the box-type shell and is provided with a contact, the bottom of the telescopic contact block is provided with a pulley, the movable wedge block is arranged at the bottom of the box-type shell and can slide in a reciprocating manner, the front end and the top surface of the movable wedge block are integrated into an inclined plane and are contacted with the pulley, and the rear end of the movable wedge block is provided with an electric push rod and another contact, so that a charging loop is formed after the contact and the contact at the top of the telescopic contact block reach designated positions; one end of the extension spring is connected with the inner wall of the box-type shell, the other end of the extension spring is connected with the front section of the telescopic contact block, and when the electric push rod drives the movable wedge block to move forwards and the top of the telescopic contact block extends out of the box-type shell, the extension spring provides tension force, so that a contact at the top of the telescopic contact block is always kept at a preset position.

The principle of this charging module is: the contact communication between the bottom of the vehicle body and the battery is realized through the seesaw-shaped telescopic contact block, so that the height of the whole mechanism in a contact retraction state is greatly reduced, and meanwhile, the contact is elastic, so that the contact tightness of the contact is guaranteed, and the contact can also be reliably contacted even if friction loss occurs; because the contact retracts when the vehicle is not charged, the vehicle does not touch the contact in normal operation, various risks can be reduced, and the storage automation is improved; the whole lower contact is modularized, the appearance of the lower contact is like a flat plate, and the installation is convenient and simple.
