Description

Technical Field

[0001] This utility model relates to the field of AGV charging brush plate technology, specifically an AGV automatic charging brush plate with temperature protection. Background Technology

[0002] Existing AGV charging typically uses DC or AC charging. A temperature sensor is usually installed on the charging pile side to monitor the temperature of the charging pile contacts for temperature protection. However, the electrode temperature of the brush plate often differs significantly from that of the charging pile contacts, leading to poor contact and other issues. Overheating of the brush plate's electrodes can cause deformation of the plastic mounting parts, or even smoke and fire, damaging the charging port and affecting charging efficiency and safety. Utility Model Content

[0003] The purpose of this invention is to provide an automatic charging brush plate for AGVs with temperature protection, which solves the problems mentioned in the background art.

[0004] Technical solution

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an AGV automatic charging brush plate with temperature protection, comprising a plastic mounting plate, charging electrodes, communication electrodes, and temperature control switches and mounting components. The plastic mounting plate is equipped with at least two charging electrodes and two communication electrodes. Temperature control switches and mounting components of the same number as the charging electrodes are mounted on the charging electrodes. The charging electrodes and communication electrodes are respectively provided with holes or buckles for mounting and connecting with the plastic mounting plate. Each charging electrode is fixed with a temperature control switch that can cut off the circuit, and each switch can control the opening and closing of the charging system.

[0006] Furthermore, the plastic mounting plate is made of insulating thermosetting plastic and has through holes or grooves. Part of it is used to fix the brush plate to the AGV body, and part of it is used to allow the electrode plate to pass through the mounting plate to connect with the internal cables.

[0007] Furthermore, the charging electrode is made of a highly conductive material. It has a flat or curved surface for contact charging with the charging station. The electrode plate has mounting holes for installing a temperature control switch, or provides space for other fixing methods of the temperature control switch. The electrode plate also has holes or similar structures for internal wiring.

[0008] Furthermore, the number of the communication electrodes is at least two, and the material is a good conductive material. They have a flat or curved surface for contact communication with the charging pile, and can transmit information about the vehicle and charging status issued by the AGV vehicle's control system to the charging pile.

[0009] Furthermore, the temperature control switch and mounting components are connected to the electrode plate by mounting components, adhesive, or other connection methods to sense the temperature of the electrode plate as accurately as possible; and temperature control switches with different threshold values ​​can be selected as needed. When the electrode plate heats up to near its threshold value, the temperature control switch can sense the temperature of the electrode plate and disconnect or connect the circuit, so as to realize the charging system and the temperature control switch of any electrode plate can independently control the opening and closing of the charging system.

[0010] This invention provides an automatic charging brush plate for AGVs with temperature protection. It has the following beneficial effects:

[0011] This temperature-protected AGV automatic charging brush plate, made of thermosetting insulating plastic, will not deform due to increased electrode temperature, thus preventing damage to the charging structure. Simultaneously, temperature control switches on the charging electrodes effectively detect when the electrode temperature exceeds the allowable range due to poor contact or other issues, promptly cutting off the recharging circuit to protect equipment and personnel safety. Furthermore, the presence of communication electrodes on the charging brush plate allows the AGV's control system to report charging anomalies to the upper-level system, or simultaneously issue alarms for monitoring personnel to locate and investigate.
