Description

Technical Field

[0001] This utility model relates to the field of mechanics, and in particular to a bidirectional telescopic mechanism integrating charging and battery swapping. Background Technology

[0002] Pure electric vehicles are environmentally friendly and energy-saving, and electric heavy trucks, electric cars, and electric light trucks are increasingly used. However, the shortage of charging piles and battery swapping stations has affected the use of electric vehicles. During holidays, there are long queues at charging piles. There are two types of charging and battery swapping robots: AGVs and RGVs. The main feature of AGVs is that they do not have tracks, while the main feature of RGVs is that they have tracks. The two types of charging and battery swapping mechanisms are used in different scenarios. Apart from the difference between having tracks and not having tracks, the battery swapping mechanism on the upper part of AGVs and RGVs is basically the same. If the upper charging and battery swapping mechanism can be standardized, it will effectively improve versatility and reduce costs. Utility Model Content

The outer wall of the battery compartment is provided with a cable reel structure, and the wire harness on the battery holder is connected to the cable reel structure.

The guide cone aligns with the flared sleeve, and the telescopic fork retracts back into the frame, placing the battery on the battery holder. The wiring harness on the battery holder connects to a reel box, which lowers the charging gun cable upon command, charging the depleted electric vehicle. The bi-directional telescopic fork can extend and retract independently from the right-side outlet of the battery compartment for battery swapping, or the battery can be retrieved from the left-side outlet and then extended through the right-side outlet for swapping.

[0007] Further preferably, the outer contour of the sleeve is trumpet-shaped.

[0014] More preferably, the pulley is mounted on the upper surface of the lifting device, and the pulley is located between two limiting blocks.

[0015] The layout can be optimized for easier operation.

[0016] Further preferably, the outer wall of the battery compartment is provided with an exhaust hole, which is an elongated through hole and is located close to the battery holder.

[0017] It facilitates heat dissipation. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figures 1-5 As shown, a bidirectional telescopic charging and swapping mechanism includes a battery compartment with a left opening 7 and a right opening 8 on its left and right sides, respectively. A frame 1 is provided on the top of the battery compartment, and a bidirectional telescopic fork 2 is installed inside the frame. The bidirectional telescopic fork extends from inside the frame to the right outlet of the battery compartment. A winch mechanism 3 is provided below the bidirectional telescopic fork. The winch mechanism is connected to a lifting device 4 via a wire rope 301. A pulley 401 is provided at the connection between the wire rope and the lifting device. A sleeve 302 is provided on the lower surface of the winch mechanism, and a guide cone 403 coinciding with the sleeve is provided on the upper surface of the lifting device. The battery is lifted by a hook 402 on the lower surface of the lifting device. A battery holder 10 is provided at the bottom of the battery compartment, and the battery fits into the battery holder. A cable reel structure 5 is provided on the outer wall of the battery compartment. The wiring harness 11 on the battery holder is connected to the cable reel structure. A charging gun cable 6 is provided below the cable reel structure.

[0026] This invention utilizes a bi-directional telescopic fork that extends from the top frame through the right-side outlet of the battery compartment. A steel wire rope is released, and four lifting devices are lowered from a height, landing on the battery. Rotating the hook retracts the steel wire rope, lifting the battery. The guide cone aligns with the flared sleeve, and the telescopic fork retracts back into the frame, placing the battery on the battery holder. The wiring harness on the battery holder connects to a reel box, which lowers the charging gun cable upon command, charging the depleted electric vehicle. The bi-directional telescopic fork can extend and retract independently from the right-side outlet of the battery compartment for battery swapping, or it can retrieve the battery from the left-side outlet and then extend it through the right-side outlet for swapping. This invention can be installed on AGVs, RGVs, or flatbed trucks for mobile battery swapping, achieving versatility.

[0027] Further optimization involves flaring out the outer contour of the sleeve, allowing for a better fit to the shape of the guide cone.

[0028] Further optimized, the lower surface of the hoisting mechanism has four hoisting openings, each with a sleeve underneath. The battery can be lifted more evenly through these four hoisting openings.

[0029] Further preferably, the upper surface of the lifting device is provided with limiting blocks, which are located on both sides of the upper surface, and the guide cone is located between the two limiting blocks. This utility model can facilitate the positioning of the wire rope through the limiting blocks.

[0030] Further preferred, there are two guide cones, and the installation positions of the guide cones are close to the limiting blocks on both sides.

[0031] Further optimization involves mounting the pulley on the upper surface of the lifting device, with the pulley positioned between two limiting blocks. This optimizes the layout and facilitates operation.

[0032] Further optimization involves providing an exhaust vent on the outer wall of the battery compartment. This vent is a long, narrow through-hole located close to the battery holder, facilitating heat dissipation.

[0033] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
