Abstract
The utility model discloses a realize safe butt joint system with charging device, including consumer and battery charging outfit, consumer and battery charging outfit are provided with two or more contacts, and battery charging outfit output direct current is equipped with current-limiting circuit for consumer, the utility model discloses can reduce the dangerous condition of people or animal emergence when charging, can reduce the cost simultaneously, the scheme is simple.
Description
Technical Field
The utility model relates to a controller technical field, in particular to realize safe butt joint system with charging device.
Background
The remote controller in the prior art has no protection measure between the electric equipment and the charging equipment, or only has a protection device for preventing the damage from continuing or expanding after the damage occurs, and the charging equipment form a path to realize charging after charging contacts of the charging equipment and the electric equipment are connected with each other. This solution leads to the risk of heating, sparking, power failure of the device, etc. when the charging contacts of the charging device or consumer form a path by touching other conductors, a large current will flow through this path. And when the charging voltage is high, the electric shock danger can occur when people or animals contact the positive electrode of the charging contact.
In another embodiment, the charging device and the consumer have contacts for communication in addition to the charging contacts. After the communication contacts of the two parties are connected, the butt joint of the two parties is confirmed in a certain mode, and then the conduction of the charging path is controlled. This kind of scheme needs to increase one or more contacts for communication on the basis of charging the contact, still needs to increase corresponding circuit to realize this procedure, makes the realization of scheme very complicated, and the cost increases.
Still other solutions have physical protection devices on the charging or consumer device, such as a recessed charging contact or a switch that requires a force to turn on the charging path. This solution can reduce or increase the difficulty of connecting the power consuming device or the charging device in an abnormal manner, but there is still a possibility of abnormal connection and danger, and for the above situation, further improvement is needed.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a can reduce the risk that takes place the short circuit when direct current equipment charges, can reduce the cost simultaneously, simple and the charging device realization safety butt joint system of scheme.
In order to solve the technical problem, the utility model discloses a technical scheme does:
the utility model provides a realize safe butt joint system with charging device, includes consumer and charging equipment, the consumer with charging equipment is provided with two or more contacts, charging equipment output direct current gives the consumer, be equipped with current-limiting circuit on the charging path.
Preferably, a voltage detection or a current detection is provided in the charging device.
Preferably, the contact is made of a conductive material.
By adopting the technical scheme, when the contacts are not connected, corresponding danger cannot be generated by using the contacts of conductor short-circuit electric equipment or charging equipment, meanwhile, electric arcs cannot be generated when the contacts are contacted, the electric equipment and the charging equipment can work in places such as dust, and meanwhile, the service life of the contacts is longer.

Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
In this embodiment, a system for implementing safe docking with a charging device, as shown in fig. 1 and fig. 2, two objects required for implementing charging docking are respectively: a consumer 1 of rechargeable batteries and a charging device 2 of a direct current power supply. The electric device 1 may be an AGV, a mobile robot, an electric car, or the like. The electric equipment 1 and the charging equipment 2 are provided with contacts 3 made of conductive materials, and at least two contacts 3 are needed for the electric equipment 1 and the charging equipment 2 which use a direct-current power supply, namely a positive electrode and a negative electrode.
A current limiting circuit 4 is designed on a charging path in the charging device 2, and the function of the current limiting circuit 4 is as follows: the current limiting circuit 4 allows a large current to pass when the direction of the current is to charge the battery. The current limiting circuit 4 allows only a very small current to pass when the current direction is opposite to the charging direction.
As shown in fig. 3, a voltage detection circuit or a current detection circuit is provided in the charging device 2. When the circuit detects that the access contact 3 of the electric equipment is contacted, the discharge switch is closed, so that the normal charging state is achieved. When the circuit detects that the consumer is separated from the contact 3, the discharge switch is closed.
A current limiting circuit: a current limiting circuit is designed on the charging circuit in the electric device 1, so that the charging current can normally pass through. The reverse current is limited to a small value to ensure safety and to enable the charging device 2 to detect the connection of the consumer.
The voltage detection circuit or the current detection circuit and the circuit on the charging equipment 2 are matched with the current limiting circuit on the electric equipment 1, so that the butt joint state of the voltage detection circuit and the current detection circuit is detected.
When the contacts are not connected, no corresponding danger is generated by using the conductor to short circuit the contact 3 of the electric equipment 1 or the charging equipment 2;
due to the current limiting circuit 4 and the discharge switch, when a human or an animal directly contacts the contact 3, a loop cannot be formed or the current is limited in a safe range, and both the human and the animal cannot sense and are safe;
because the safety device is safe to foreign matters, people, animals and the like, the contact 3 does not need additional design to improve the safety, so that the design of the electric equipment 1 and the charging equipment 2 is more concise;
when the contact 3 is contacted, electric arcs cannot be generated, so that the equipment can work in places such as dust and the like, and the service life of the contact is longer;
only two contacts 3 are needed to achieve the docking detection and charging functions.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
