[0028] The exemplary embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the following description is only exemplary in nature and is not intended to limit the present application, application or use.

[0029] The present application will now be further described. In the following paragraphs, different aspects of the present application are defined in more detail. Unless clearly indicated to the contrary, each aspect so defined may be combined with any other aspect(s). In particular, any feature indicated as being preferred or advantageous may be combined with any other feature(s) indicated as being preferred or advantageous.

[0030] See attached Figure 1 , shows a sling 100 according to the principles of the present application. The sling 100 includes a base plate 110 and a first wall 120 and a second wall 130, wherein the first wall 120 and the second wall 130 extend along the edge thereof toward one side of the base plate 110 and surround the base plate 110 so that the base plate and the first wall and the second wall form a box-like structure with an opening, and wherein the first wall 120 and the second wall 130 are detachably connected. The interior of the second wall 130 may be a cavity, so that a battery pack 140 may be placed in the cavity. Since the battery pack 140 is arranged inside the second wall 130, the second wall 130 can protect the battery pack 140 to prevent the battery pack 140 from colliding with other objects during use and being damaged or falling off, and at the same time, it also makes reasonable use of space and avoids installing the battery pack 140 on the base plate 110 or other devices to occupy too much space. The base plate 110 may be rectangular, circular, elliptical, polygonal, or irregular in shape, etc. When the base plate 110 is rectangular (such as Figure 1 As schematically shown), the first wall 120 may extend along two opposite sides of the bottom plate 110, preferably perpendicular to the bottom plate, and the second wall 130 may extend along the other two opposite sides of the bottom plate 110, preferably perpendicular to the bottom plate.

[0031] See attached Figure 2 The battery pack 140 includes a battery mounting frame 141 and a plurality of battery cells 142 mounted in the battery mounting frame 141. The battery mounting frame 141 includes a positive electrode connecting frame 141a and a negative electrode connecting frame 141b, wherein the positive electrode connecting frame 141a is connected to the positive electrode of the battery cell 142, and the negative electrode connecting frame 141b is connected to the negative electrode of the battery cell 142. The battery pack 140 may be in an elongated shape to adapt to the shape of the second wall 130. For example, the battery cells 142 in the battery pack may be arranged in one row or two rows so that the entire battery pack 140 has a width that can be adapted to the second wall 130.

[0032] See attached Figure 3 and attached Figure 4The second wall 130 is provided with a connection hole 131 so as to be connected to the first wall 120 by bolts or rods. The rods used for connection may be metal tubes or carbon fiber tubes. The second wall 130 may be provided with a hollow 132, which is not only conducive to heat dissipation of the battery pack 140 during operation, but also conducive to reducing the overall mass of the sling 100. The gap between the second wall 130 and the battery pack 140 may be filled with a flexible material, such as rubber, silicone, foam, etc., so as to increase the stability and shock resistance of the battery pack 140.

[0033] See attached Figure 1 The bottom plate 110 is provided with a winch unit 150, wherein the winch unit 150 includes a winch body 151, a rope (not shown) wound around the winch body 151, a motor 152 connected to the winch body 151, and preferably a rope guide mechanism 153. The battery pack 140 is electrically connected to the motor 152 to provide power to the motor 152 to drive the winch body 151 to rotate. The number of winch units 150 can be more than 2, for example, 4. It is easy for those skilled in the art to understand that the sling 100 according to the principle of the present application can be used as a lifting device, that is, as a fixed end, to lift the load-bearing device with the object to be lifted located below it by retracting and releasing the rope; it can also be used as a load-bearing device, that is, as a movable end, to lower or rise below the lifting device by retracting and releasing the rope to carry the object to be lifted. When the sling 100 is used as a load-bearing device, it can also be provided with a hook, a gripper or a receiving box to hook, grab or accommodate the object to be lifted.

[0034] See attached Figure 1 and attached Figure 6The sling 100 may further include a propeller mounting frame 160 for mounting a propeller 161. The propeller 161 may be a propeller, or a gas or liquid nozzle. The propeller 161 may be electrically connected to the battery pack 140 so that the battery pack 140 provides it with power. When the sling 100 is used as a load-bearing device, if it encounters wind force during the lifting process and causes the sling 100 to swing horizontally, the propeller 161 may provide a force that is opposite to the wind force and equal in magnitude, thereby preventing the sling from swinging. Furthermore, when the sling 100 is used as a load-bearing device and is descending, if it is not directly above the cargo or the predetermined delivery point, the propeller 161 may provide a corresponding driving force so that the sling 100 is close to the cargo or directly above the predetermined delivery point so as to grab or deliver the cargo. The propeller mounting frame 160 may include a first body 160a and a second body 160b. As shown, the first body 160a and the second body 160b are both substantially plate-shaped, and the second body 160b is disposed at opposite ends of the first body 160a and is respectively perpendicular to the first body 160a. As also shown in the figure, the first body 160a is parallel or substantially parallel to the first wall 120, and the second body 160b and the second wall 130 are in the same direction. The propeller mounting frame 160 is disposed on the outside of the first wall 120 and is detachably connected to the second wall 130 through the second body 160b, so that there is a space between the propeller mounting frame 160 and the first wall 120, so that when the propeller as the propeller 161 is running, the airflow can have enough flow space. The first body 160a and the second body 160b can both be provided with propellers, so as to provide forces in different directions to the sling 100 by controlling the switches of each propeller.

[0035] See attached Figure 1 The sling 100 may also be provided with a control module 170 and a detection module (not shown), wherein the detection module is capable of detecting the swing direction and swing strength of the sling 100 and transmitting the relevant information to the control module 170, and the control module 170 may control the switch and thrust size of the corresponding propeller 161 according to the information provided by the detection module, thereby providing appropriate thrust to prevent the sling 100 from swinging.

[0036] See attached Figure 1, the first wall 120 may be provided with a hollow 121, and the thruster mounting frame 160 may be provided with a hollow 162, so as to reduce the weight of the sling 100. Advantageously, the rope guide mechanism 153 may be provided in the thruster mounting frame 160, for example, it may be provided at the connection between the first body 160a and the second body 160b of the thruster mounting frame 160. The rope guide mechanism 153 may be integrally formed with the thruster mounting frame 160, or may be connected to the thruster mounting frame 160 by bolts. After the rope extends from the winch body 151, it may pass through the hollow 121 to reach the rope guide mechanism 153, and continue to extend after passing through the rope guide mechanism 153.

[0037] See attached Figure 5 and attached Figure 6 The sling 100 may also be provided with a top cover 180, wherein the top cover 180 can be detachably connected to the first wall 120 and the second wall 130, so that it can cover the top of the bottom plate 110, that is, cover the opening of the box-like structure, thereby providing better protection for the equipment arranged in the bottom plate 110.

[0038] The sling 100 according to the principles of the present application can be used in various cranes and also in various aircrafts.

[0039] The present application also provides an aircraft, which includes a sling 100 according to the principles of the present application. The aircraft according to the principles of the present application can be a manned aircraft or an unmanned aircraft.

[0040] The sling according to the principle of the present application improves the integrity of the battery pack and the wall and the safety of the battery pack by arranging the battery pack in the wall, rationally utilizes the space of the sling, and makes the spatial layout of the sling more reasonable.
