Description

Technical Field

[0001] This utility model relates to the field of charging technology for forklift AGVs, and specifically to a charging structure for forklift AGVs. Background Technology

[0002] Existing forklift charging methods mostly use side-mounted brush plates and blocks. The corresponding charging pile structure is complex, and the brush plates and blocks are prone to oxidation during long-term use, which can lead to poor contact and affect the charging effect. At the same time, the manufacturing cost of this type of charging mechanism is high, which is not conducive to large-scale promotion and application, and cannot meet the needs of efficient use of site space. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a charging structure for forklift AGVs, so as to solve the technical problems of existing forklift charging mechanisms being complex in structure, prone to poor contact, high in cost, and large in space.

[0004] To solve the above problems, the technical solution provided by this utility model is as follows:

[0005] A charging mechanism for a forklift AGV includes a charging base and a charging pile; the charging base is mounted on the forklift AGV, and the charging pile is mounted on the ground; the charging pile is provided with a charging head; the charging base has a seat slope, and the charging head has a head slope, the seat slope and the head slope being adapted to each other; the charging base has a conductive port, and the charging head has a conductive contact, the conductive port and the conductive contact being adapted to each other; the outer shell of the charging base and the outer shell of the charging head are both made of insulating material; the charging pile has a fixing hole.

[0006] The charging base receives electrical energy and conducts it to the AGV battery, while the charging pile provides power and is fixed to the ground.

[0011] Optionally, the charging pile is located inside the fork of the forklift AGV when it is charging, and the volume of the charging pile is less than or equal to the space covered by the length of the fork of the forklift AGV.

[0012] To save space to the maximum extent, avoid charging piles occupying extra area, and improve site utilization efficiency.

[0013] Alternatively, the insulating material may be plastic or epoxy resin.

[0014] It provides good electrical insulation to prevent leakage, while also possessing a certain degree of mechanical strength and environmental resistance.

[0015] Alternatively, the conductive port may be a metal conductive port.

[0016] It provides a low-resistance, highly conductive electrical connection path to ensure efficient power transmission.

[0035] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0036] Example 1

[0037] Combined with appendix Figure 1-7 A charging mechanism for a forklift AGV includes a charging base 11 and a charging pile 2; the charging base 11 is mounted on the forklift AGV, and the charging pile 2 is mounted on the ground; the charging pile 2 is equipped with a charging head 21; combined with the attached... Figure 3 The charging base 11 has a sloping surface 111, which is combined with the attached Figure 4 The charging head 21 has a beveled surface 211, which is combined with the attached Figure 5 , 6 The inclined surface 111 of the charging base is adapted to the inclined surface 211 of the charging head; the charging base 11 is provided with a conductive port 103, and the charging head 21 is provided with a conductive contact 203, the conductive port 103 and the conductive contact 203 are adapted to each other; the outer shell of the charging base 11 and the outer shell of the charging head 21 are both made of insulating material; the charging pile 2 is provided with fixing holes for attaching accessories. Figure 1-7 When the AGV approaches the charging pile 2, the seat ramp 111 and the head ramp 211 slide into contact with each other, guiding the charging head 21 to gradually insert into the charging base 11. The ramp design allows for precise positioning even with some positional deviation through mechanical guidance. After full insertion, the conductive contact 203 and the conductive port 103 form an electrical connection, initiating charging. The insulating outer shell prevents external short circuits or the risk of electric shock.

[0038] The fixing hole 202 is used to fix the charging pile 2 to the ground with fasteners, which are expansion bolts. The expansion bolts are inserted into the pre-drilled holes in the ground. When tightened, the tail of the bolt expands and forms a mechanical lock with the ground to prevent the charging pile 2 from shifting or tilting.

[0039] The charging base 11 is fixedly connected to the forklift AGV; the charging head 21 is fixedly connected to the charging pile 2. The charging base 11 is firmly installed on the AGV body by means of bolts, welding or clips, and the charging head 21 is also fixed to the charging pile 2 to ensure structural rigidity during the docking process.

[0040] When charging, charging pile 2 is located inside the forks of the forklift AGV. The volume of charging pile 2 is less than or equal to the space covered by the length of the fork of the forklift AGV 1. When the AGV enters the charging position, the fork naturally surrounds charging pile 2. The height and width of charging pile 2 are controlled within the internal space of the fork, achieving "invisible" charging.

[0041] The insulating material is plastic or epoxy resin. Plastic or epoxy resin materials are non-conductive, effectively isolating the high voltage during charging and ensuring operational safety.

[0042] The conductive port 103 is a metal conductive port 103. The conductive contact 203 is a metal conductive contact 203. Metal materials (such as copper or gold-plated alloys) have good conductivity and wear resistance, and can maintain good contact after multiple insertions and removals. In this embodiment, both the conductive port 103 and the conductive contact 203 are made of copper. Copper has excellent conductivity and corrosion resistance, which can ensure the conductivity stability during long-term use. The tilt angles of the seat slope 111 and the head slope 211 can be adjusted according to the actual docking requirements, and are not limited to 30°. As long as the two are compatible, the guiding docking function can be realized.

[0043] Both the seat ramp 111 and the head ramp 211 are inclined planes. During the docking process, the inclined planes generate a lateral force, which pushes the charging head 21 to automatically correct its position until it is fully inserted.

[0044] The charging base 11 is fixedly installed on the side of the forklift AGV1 by bolts. The outer shell of the charging base 11 is made of epoxy resin, and the inside of the outer shell is provided with a conductive port 103 made of metal. One side of the charging base 11 is provided with a seat slope 111, which is an inclined plane with an angle of 30° to the horizontal plane.

[0045] The charging pile 2 is set at a preset position on the ground. The charging pile 2 has an integrally formed charging head 21. The outer shell of the charging head 21 is also made of epoxy resin. One end of the charging head 21 is provided with a head slope 211 that matches the seat slope 111. The inside of the charging head 21 is provided with a metal conductive contact 203 that matches the conductive port 103.

[0046] Combined with appendix Figure 2 The bottom of charging pile 2 has four fixing holes for connection with the attachment. Figure 1-7 The four fixing holes 202 are located at the four corners of the bottom of the charging pile 2. Expansion bolts are passed through the fixing holes to attach the charging pile. Figure 1-7 Fix charging pile 2 to the ground.

[0047] Combined with appendix Figure 7 When the forklift AGV1 needs to be charged, the forklift AGV1 is moved so that the fork teeth are aligned with the charging pile 2. Under the guidance of the head inclined surface 211 and the seat inclined surface 111, the charging head 21 is smoothly inserted into the charging base 11. At this time, the conductive contact 203 contacts the conductive port 103 to form a current path and realize the charging of the forklift AGV1. During the charging process, the charging pile 2 is completely located inside the fork teeth of the forklift AGV1 and does not occupy the space outside the fork teeth.

[0048] Charging pile installation: First, through the fixing holes 202 at the bottom of the charging pile 2, use expansion bolts (not limited to) to pass through the fixing holes 202 to stably fix the charging pile 2 in the preset position on the ground, providing a fixed foundation for subsequent charging docking; the charging pile 2 has an integrally formed charging head 21, the outer shell of the charging head 21 is made of epoxy resin, one end of which has a head bevel 211, and the inside has a metal conductive contact 203. The charging base 11 is fixed to the side of the forklift AGV1 with bolts. The outer shell of the charging base 11 is also made of epoxy resin, and one side of it has a seat bevel 111 that matches the head bevel 211 of the charging head 21 (the seat bevel 111 is an inclined plane with a 30° angle to the horizontal plane, and the angle can be adjusted as needed). The charging base 11 has a metal conductive port 103 that matches the conductive contact 203 (both the conductive port 103 and the conductive contact 203 are made of copper to ensure conductive stability).

[0049] Charging docking guidance: When the forklift AGV1 needs to be charged, control the forklift AGV1 to move so that the fork teeth of the forklift AGV1 are aligned with the charging pile 2 fixed on the ground; during the movement, the seat slope 111 of the charging base 11 and the head slope 211 of the charging head 21 are matched due to the structural adaptation and have a guiding effect, ensuring that the charging head 21 can be accurately and smoothly inserted into the charging base 11.

[0050] Current path formation and charging start-up: When the charging head 21 is inserted into the charging base 11, the conductive contact 203 inside the charging head 21 is in close contact with the conductive port 103 inside the charging base 11, forming a complete current path. At this time, the current is transmitted to the forklift AGV1 through the path to realize the charging operation of the forklift AGV1.

[0051] Space Occupancy Status: Throughout the entire charging process, the charging pile 2 is located entirely inside the fork teeth of the forklift AGV1, without occupying the space outside the fork teeth of the forklift AGV1, thus ensuring the utilization rate of the site.

[0052] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
