[0002] With the growing global demand for clean energy and sustainable transportation, the shipping industry is facing unprecedented challenges and opportunities. Traditional ships rely heavily on fossil fuels, which not only leads to serious environmental pollution but also raises questions about their economic viability as resources become increasingly depleted. Therefore, developing new clean energy ships, especially battery-swapping ships, has become an inevitable trend in the industry. Battery swapping on ships requires transferring batteries from shore to the electric vessel, necessitating the use of battery-swapping vehicles. These vehicles require battery lifting equipment to hoist and transport the batteries to their target location.

[0003] The inventors discovered that the battery lifting devices on some existing battery swapping vehicles are prone to swaying during transport, resulting in low battery lifting efficiency. Utility Model Content

[0030] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0031] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0032] The following describes in detail, with reference to the accompanying drawings, the specific structure of a battery swapping hoisting device provided by this utility model and its corresponding technical effects.

[0033] Please refer to Figures 1-3 This utility model provides a battery swapping hoisting device 400, which includes a first platform 410, a second platform 420, and a hoisting device 480. The first platform 410 is equipped with a horizontal holding system 430, which is used to connect to the boom 200. The second platform 420 is connected to the first platform 410 via a floating chain 440. The hoisting device 480 is connected to the second platform 420 and is used to hoist the battery. The horizontal holding system 430 is used to keep the hoisting device 480 in a horizontal state.

[0034] Understandably, in some existing battery swapping vehicles 1, the lifting device 480 is prone to pitching and swaying during the transfer of the battery swapping lifting device by the boom 200, making it difficult to lift the battery and resulting in low battery lifting efficiency. However, in this embodiment, the horizontal holding system 430 can keep the lifting device 480 in a horizontal state, thereby improving the lifting efficiency of the lifting device 480.

[0035] It should be noted that the horizontal state in this embodiment should not be limited to a strictly horizontal state; it is sufficient as long as the lifting device 480 is kept roughly horizontal.

[0036] It should be noted that in this embodiment, when the battery swapping hoisting device is in a stationary state under the action of gravity after being connected to the boom 200, the first platform 410, the second platform 420 and the hoisting device 480 are in a horizontal state.

[0037] Since the first platform 410 is connected to the second platform 420 through the floating chain 440, the first platform 410 and the second platform 420 can float in the height direction under the action of the floating chain 440. The first platform 410 and the second platform 420 can also float in the left and right direction or the front and back direction. When hoisting batteries, it is also convenient for the lifting device 480 connected to the second platform 420 to adaptively hoist batteries at different positions, thereby improving the hoisting efficiency of batteries.

[0038] In detail, in this embodiment, there are four floating chains 440, which are respectively set at the four corners of the first platform 410 to ensure that the first platform 410 and the second platform 420 are relatively horizontal.

[0039] Of course, in other embodiments, the number of floating chains 440 can be other numbers, as long as it can ensure that the first platform 410 and the second platform 420 are in a horizontal state when they are stationary under the action of gravity.

[0040] In detail, a first mounting base 411 is provided on the side of the first platform 410 away from the second platform 420, so as to facilitate connection with the horizontal holding system 430 and avoid the horizontal holding system 430 occupying the space between the first platform 410 and the second platform 420, and also facilitate the connection between the horizontal holding system 430 and the boom 200.

[0041] In this embodiment, the leveling system 430 includes a leveling detection element 436, a second mounting base, a first drive assembly, and a connecting shaft 433. The connecting shaft 433 passes through the first mounting base 411 and the second mounting base. The connecting shaft 433 is fixedly connected to the first mounting base 411 and rotatably connected to the second mounting base. The drive assembly is drively connected to the connecting shaft 433. The second mounting base is used to connect to the boom 200. The leveling detection element 436 is mounted on the first platform 410 and is communicatively connected to the first drive assembly.

[0042] Understandably, the first drive assembly can drive the first mounting base 411 to rotate along with the connecting shaft 433. That is, the first mounting base 411 can rotate around the axis of the connecting shaft 433 in a first direction or around the connecting shaft 433 in a second direction, the first direction being opposite to the second direction. For example, when the horizontal detection element 436 detects that the lifting device 480 is subjected to an external force, causing the first platform 410 to tend to rotate around the axis of the connecting shaft 433 in the first direction, the first drive assembly can provide a force to the connecting shaft 433 to rotate around the second direction, thereby counteracting the external force that causes the first platform 410 to rotate in the first direction, so that the first platform 410 is in a horizontal state.

[0043] Conversely, when the horizontal detection component 436 detects that the lifting device 480 is subjected to an external force, causing the first platform 410 to tend to rotate around the axis of the connecting shaft 433 in the second direction, the first drive component can provide the connecting shaft 433 with a force that rotates around the first direction, thereby counteracting the external force that causes the first platform 410 to rotate in the second direction, so that the first platform 410 is in a horizontal state.

[0044] In this embodiment, in order to ensure the stability of the first mounting base 411 and the second mounting base on the connecting shaft 433, the first mounting base 411 includes two first connecting plates 4111 spaced apart along the axial direction of the connecting shaft 433, and the second mounting base includes a mounting body 437 and two second connecting plates 431 spaced apart along the axial direction of the connecting shaft 433. Both second connecting plates 431 are connected to the mounting body 437, and the mounting body 437 is used to connect to the boom 200.

[0045] The two ends of the connecting shaft 433 are fixedly connected to two first connecting plates 4111 respectively. The second connecting plate 431 is sleeved on the connecting shaft 433 and located between the two first connecting plates 4111. The first driving assembly includes a first driving member 432, a first gear 434 and a second gear 435. The first driving member 432 is installed on the second connecting plate 431. The first gear 434 is sleeved on the drive shaft of the first driving member 432. The second gear 435 is sleeved on the connecting shaft 433 and meshes with the first gear 434.

[0046] In this embodiment, the first gear 434 is a pinion, the second gear 435 is a gear, and the first driving component 432 includes a drive motor and a reducer. The drive motor is connected to the reducer, and the output shaft of the reducer is fitted with the first gear 434.

[0047] Optionally, in order to improve the efficiency of keeping the spreader 480 horizontally, there are two first drive assemblies. The first drive members 432 of the two first drive assemblies are respectively mounted on two second connecting plates 431, and the second gears 435 of the two first drive assemblies are spaced apart along the axial direction of the connecting shaft 433.

[0048] Optionally, in some embodiments, the horizontal detection element 436 is a gyroscope, which is communicatively connected to the first drive element 432. A gyroscope is a device used to measure or maintain the angular velocity and orientation of an object. It operates based on the principle of conservation of angular momentum and is widely used in aerospace, marine, and robotics fields. It can accurately measure the rotational speed around one or more axes. It can help determine the attitude of the lifting device 480 in three-dimensional space, thereby maintaining the object's orientation stability through the first drive element 432.

[0049] Of course, in some other embodiments, the horizontal detection element 436 can also be other types of detection elements.

[0050] Optionally, in some embodiments, the battery swapping hoisting device 400 further includes a rotation drive assembly 450. The second platform 420 is connected to the lifting device 480 through the rotation drive assembly 450. The rotation drive assembly 450 is used to rotate the lifting device 480 around a preset axis, which is parallel to the height direction. The rotation drive assembly 450 can drive the lifting device 480 to rotate in the horizontal direction, so that the lifting device 480 can hoist batteries in different postures, thereby improving the battery hoisting efficiency.

[0051] The rotation drive assembly 450 may include a rotation drive component and a transmission assembly connected to each other. The transmission assembly is connected to the lifting device 480 and drives the lifting device 480 to rotate under the action of the rotation drive component. It is easy to understand that the rotation of the lifting device 480 relative to the second rotation platform is a conventional setting of the mechanical structure, and it will not be described in detail here.

[0052] The lifting device 480 is also equipped with a positioning sensor 460. Optionally, in some embodiments, the positioning sensor 460 is an RTK (Real-Time Kinematic) positioning sensor 460. The positioning sensor 460 is used to communicate with the industrial control computer 300 and to provide the position coordinates of the lifting device 480. It can be understood that the industrial control computer 300 can be a control module on the battery swapping vehicle 1. By transmitting the position coordinates of the lifting device 480 through the positioning sensor 460, the industrial control computer 300 can control the accuracy of the lifting arm 200 to move the lifting device 480, and facilitate the lifting device 480 to move above the battery to grab the battery, thereby improving the accuracy and efficiency of battery lifting.

[0053] Optionally, in some embodiments, the lifting device 480 is also equipped with a descent position switch. The descent position switch includes a proximity switch 471, a fixed sleeve 472, a spring, and a telescopic rod 473. The proximity switch 471 is installed on the side of the lifting device 480 near the second platform 420. The telescopic rod 473 passes through the fixed sleeve 472. The spring is connected to both the telescopic rod 473 and the fixed sleeve 472. The spring has a preset pressure to make the telescopic rod 473 move downward relative to the fixed sleeve 472 by a first preset height. When the lifting device 480 is lowered to the position, the lower part of the telescopic rod 473 will be subjected to an upward force. After the telescopic rod 473 can overcome the preset pressure of the spring and move upward by a second preset height, the proximity switch 471 sends a position signal. The proximity switch 471 can communicate with the industrial control computer 300 of the electric swapping vehicle 1 to ensure that the lifting device 480 stops after being lowered to the position.

[0054] This utility model embodiment also provides a battery swapping vehicle 1, which includes the aforementioned battery swapping hoisting device 400. It should be noted that the battery swapping vehicle 1 includes a vehicle body 100, a boom 200, an industrial control computer 300, and the aforementioned battery swapping hoisting device 400. The boom 200 and the industrial control computer 300 are mounted on the vehicle body 100. The end of the boom 200 away from the vehicle body 100 is connected to the mounting body 437. The industrial control computer 300 can communicate with the boom 200, the RTK positioning sensor 460, and the proximity switch 471.

[0055] In summary, this utility model embodiment provides a battery swapping vehicle 1 and a battery swapping hoisting device 400. The battery swapping vehicle 1 includes the battery swapping hoisting device 400, which includes a first platform 410, a second platform 420, and a lifting device 480. The first platform 410 is equipped with a horizontal holding system 430, which is used to connect to the boom 200. The second platform 420 is connected to the first platform 410 via a floating chain 440. The lifting device 480 is connected to the second platform 420 and is used to hoist the battery. The horizontal holding system 430 is used to keep the lifting device 480 in a horizontal state. The horizontal holding system 430 can keep the lifting device 480 in a horizontal state, thereby improving the hoisting efficiency of the lifting device 480. Furthermore, under the action of the floating chain 440, the first platform 410 and the second platform 420 can float in the height direction, and the first platform 410 and the second platform 420 can also float in the left and right or front and back directions. When hoisting batteries, it is also convenient for the lifting device 480 connected to the second platform 420 to adaptively hoist batteries at different positions, thereby improving the hoisting efficiency of batteries.

[0056] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
