Description

Technical Field

[0001] This utility model relates to the field of charging brush plate technology, and in particular to a high-current charging brush plate for forklift AGVs. Background Technology

[0002] Charging brushes are one of the commonly used charging contact structures on forklift AGVs. Due to their simple structure and wide applicability, they are widely used in forklift AGVs. Currently, most forklift AGVs on the market use charging brushes for charging. This mechanism enables automatic charging of forklift AGVs, achieving high-current, high-speed charging. With the deepening development of the forklift AGV industry, forklift AGVs are increasingly used in scenarios with high precision requirements, such as production line docking, warehouse docking, and equipment docking, placing extremely high demands on the automatic and rapid charging of automated equipment.

[0003] Existing charging brush plates have the following drawbacks: First, traditional charging brush plates have certain limitations in their manufacturing process, resulting in relatively high internal resistance. When current passes through the charging brush plate, the resistance generates a large amount of heat, causing the charging brush plate to heat up significantly during charging. This heating not only reduces charging efficiency but may also damage the charging equipment and the vehicle being charged. Furthermore, excessively high temperatures may trigger safety hazards, making traditional charging brush plates significantly inadequate in terms of safety and unable to provide safe and reliable charging services for vehicles. Second, due to their design limitations, traditional charging brush plates are susceptible to external impacts and wear during long-term use, easily leading to structural damage. Once the charging brush plate is damaged, it will not only affect its charging performance but may also cause further damage to the charging equipment and the vehicle being charged. Utility Model Content

[0004] The purpose of this invention is to provide a high-current charging brush plate for forklift AGVs to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-current charging brush plate for forklift AGVs, including a brush plate base, a brush plate electrode plate fixedly connected to the brush plate base, an electrode plate pressure plate fixedly connected to one side outer wall of the brush plate electrode plate, a limiting groove is formed on the electrode plate pressure plate, a first through hole is formed on one side inner wall of the limiting groove, a brush plate electrode post is sleeved in the first through hole, an anti-rotation block and a fixing post are provided on the brush plate electrode post, and the anti-rotation block is set in the limiting groove. A first mounting groove is formed on one side outer wall of the brush plate corresponding to the position of the fixing post, and the fixing post is sleeved in the first mounting groove.

[0006] As a further technical solution of this utility model, a positioning groove is provided on one side of the outer wall of the brush plate base at the position corresponding to the position of the brush plate electrode, and the brush plate electrode is fixedly connected in the positioning groove.

[0007] As a further technical solution of this utility model, a second mounting groove is provided in the positioning groove, and an electrode plate pressure plate is provided in the second mounting groove.

[0008] As a further technical solution of this utility model, a second through hole is provided on one side of the outer wall of the electrode plate pressure plate, a fixing screw is sleeved in the second through hole, and the other end of the fixing screw is threaded to the brush plate electrode plate.

[0009] As a further technical solution of this utility model, a nut is threaded onto the brush plate pole.

[0010] As a further technical solution of this utility model, a gasket is sleeved on the brush plate pole.

[0011] As a further technical solution of this utility model, the number of gaskets (10) is at least one.

[0012] As a further technical solution of this utility model, the number of gaskets (10) is 2, and the materials of the 2 gaskets are different.

[0013] As a further technical solution of this utility model, the number of gaskets (10) is 3, two of the three gaskets are made of the same material, and the two gaskets of the same material are not arranged adjacent to each other.

[0014] As a further technical solution of this utility model, one end of the brush plate pole is threaded with a nut.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model connects the brush plate and the brush plate post into a whole through an interference fit, ensuring good contact between the brush plate and the brush plate post. This effectively solves the problem of excessive resistance caused by poor contact in traditional charging brush plates, thereby avoiding the phenomenon of brush plate overheating during charging. This not only improves charging efficiency but also ensures the safety and stability of the charging process. Furthermore, the brush plate post with a stepped shaft structure is designed to make the brush plate post more structurally stable. Through the cooperation between the anti-rotation block and the limiting groove on the plate pressure plate, the rotation of the brush plate post is effectively blocked, which not only enhances the durability of the brush plate post, making it less susceptible to damage during use, but also further improves the overall stability and reliability of the charging brush plate.
