Description

Technical Field

[0001] The utility model belongs to the technical field of new energy vehicles, and particularly relates to a wire rope anti-loosening structure for a roof-mounted battery swapping system. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels but adopt new in-vehicle power devices), integrating advanced technologies in vehicle power control and drive, and forming vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include: hybrid vehicles, pure electric vehicles, fuel cell vehicles, hydrogen engine vehicles, gas vehicles, alcohol ether vehicles, and so on.

[0003] During the process of realizing the battery pack picking and placing, the commercial vehicle roof-mounted battery swapping system needs lifting function and in-place delay stop function. Its lifting and stopping frequencies are extremely high. When in-place delay stop occurs, the wire rope is in a loose state, and wire rope winding misalignment is likely to occur when lifting is restarted again, which may cause safety accidents in severe cases. Content of the Utility Model

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

[0005] A wire rope anti-loosening structure for a roof-mounted battery swapping system, comprising a battery swapping structure and a lifting device structure connected to the battery swapping structure through an anti-loosening structure;

[0006] The anti-loosening structure includes at least four groups of pulley blocks, a wire rope wound around the pulley blocks, and a tensioning component, and the tensioning component is used for tensioning the wire rope on the pulley blocks;

[0007] The battery swapping structure is provided with a power source for driving the lifting device structure to move upward / downward;

[0008] The lifting device structure includes a lifting seat plate and clamping jaws installed on the lifting seat plate, and the clamping jaws are used for clamping the battery pack.

[0009] Further, the pulley block includes a pulley seat fixed on the battery swapping structure, a fixed pulley hinged on the pulley seat, and at least two groups of movable pulleys connected by the wire rope. The two groups of movable pulleys are installed on a pulley connecting piece, and the wire rope passes through one group of movable pulleys, bypasses the fixed pulley, and then passes out from the other group of movable pulleys.

[0010] Further, the tensioning assembly includes a guide post fixed on the lifting seat plate and an elastic element sleeved on the guide post. The pulley connecting member is sleeved on the guide post. A limiting member is provided at one end of the guide post away from the lifting seat plate. The elastic element is arranged between the limiting member and the pulley connecting member. When the steel wire rope pulls the movable pulley, the elastic element can be compressed to tension the movable pulley.

[0011] Further, the anti-loosening structure further includes a sensor fixed on the lifting seat plate, and the sensor is used to detect the relative position between the lifting seat plate and the battery pack unlocking mechanism.

[0012] Further, the guide post is double-layered and includes a suspension rod and a sleeve. The elastic element is sleeved on the sleeve. When compressed, the suspension rod slides in the sleeve.

[0013] Advantages of the present utility model:

[0014] When the battery pack is taken in the battery swapping system of the present utility model, the steel wire rope loosens and the hoisting structure descends. When the hoisting structure descends to the battery pack unlocking position, since the hanging lock positions at the four corners of the battery pack are at different heights, it is necessary to delay the descent. When all the sensors respond, the hoisting structure stops descending. At this time, due to the uneven height, the steel wire rope may become loose, and the spring of the tensioning assembly stretches to make the pulley vertically descend along the guide of the suspension rod to tighten the steel wire rope, thereby avoiding the phenomenon of winding and dislocation of the steel wire rope.

[0015] The above description is only an overview of the technical solution of the present utility model. In order to be able to understand the technical means of the present utility model more clearly and implement it in accordance with the content of the specification, the following describes the preferred embodiments of the present utility model in detail in conjunction with the accompanying drawings.
