[0032] According to one aspect of the present application, a lifting tool is provided, such as Figure 1 and Figure 2As shown, the lifting tool is used for lifting the battery pack, and the battery pack includes a hanging ear 5 and a part to be lifted 4, and the hanging ear 5 is arranged on the part to be lifted 4. The lifting tool includes a first fixing member 1, a second fixing member 2 and a connecting member 3, the first fixing member 1 and the second fixing member 2 are arranged at intervals, and the first fixing member 1 and the second fixing member 2 enclose a receiving space 6, and the receiving space 6 is used to accommodate the part to be lifted 4, and the first fixing member 1 and the second fixing member 2 are both connected to the connecting member 3, and the connecting member 3 is used to drive the first fixing member 1 and the second fixing member 2 to move closer to or away from each other. During the use of the lifting tool of the present application, the part to be lifted 4 is arranged in the receiving space 6 enclosed by the first fixing member 1 and the second fixing member 2, and the connecting member 3 drives the first fixing member 1 and the second fixing member 2 to move closer to each other, so that the two surfaces of the part to be lifted 4 facing each other are respectively fitted with the first fixing member 1 and the second fixing member 2, and then the lifting can be completed by applying force to the connecting member 3. During the hoisting process, the connecting member 3 will apply force to the two surfaces of the hoisting member 4 through the first fixing member 1 and the second fixing member 2 respectively, and the hanging ear 5 is no longer subjected to force, thus reducing the risk of damage to the hanging ear 5.

[0033] In the embodiments of the present application, Figure 5 As shown, the connecting member 3 includes a connecting portion 31, a hoisting portion 32 and a connecting portion 33. The connecting portion 31 is rod-shaped, the hoisting portion 32 is annular, and the connecting portion 33 is truncated. The connecting portion 31 and the hoisting portion 32 are connected by the connecting portion 33. The connecting portion 31 passes through the first fixing member 1 and the second fixing member 2, and the hoisting portion 32 is located on the side of the first fixing member 1 that is opposite to the second fixing member 2. When the battery pack is hoisted by using the hoisting tool, the first fixing member 1 and the second fixing member 2 can be respectively arranged on the opposite sides of the hoisting member 4 to be hoisted, so that the hoisting member 4 is located in the accommodating space 6, and then the connecting portion 31 passes through the first fixing member 1 and the second fixing member 2, and the first fixing member 1 and the second fixing member 2 are forcefully applied through the connecting portion 31, so that the first fixing member 1 and the second fixing member 2 are close to each other, until the two opposite surfaces of the hoisting member 4 to be hoisted are respectively fitted with the first fixing member 1 and the second fixing member 2. At this time, a structure such as a steel wire rope can be passed through the hole of the hoisting portion 32 to achieve the hoisting of the battery pack.

[0034] Optionally, the connecting portion 31 , the hanging portion 32 and the connecting portion 33 may be integrally formed.

[0035] Furthermore, a thread is provided on the connection part 31 of the connector 3, and the connection part 31 can be threadedly connected to the first fixing part 1 and the second fixing part 2 respectively, and the direction of rotation of the thread on the first fixing part 1 is opposite to the direction of rotation of the thread on the second fixing part 2. In this way, the first fixing part 1 and the second fixing part 2 can be brought close to each other by screwing the connector 3 to hoist the battery pack. After the hoisting is completed, the connector 3 can be screwed in the reverse direction to make the first fixing part 1 and the second fixing part 2 move away from each other until the connector 3 is completely detached from the first fixing part 1 and the second fixing part 2, thereby removing the hoisting tool from the to-be-hoisted part 4 of the battery pack.

[0036] In the embodiments of the present application, Figure 3 As shown, the first fixing member 1 is in the shape of a cuboid, and includes a first plane 11 and a notch 12. The first plane 11 is the plane of the first fixing member 1 facing the second fixing member 2, and the notch 12 is recessed from the first plane 11 to the inside of the first fixing member 1. When the battery pack is hoisted using a hoisting tool, the first plane 11 fits with the upper surface of the part to be hoisted 4, and the ear 5 on the part to be hoisted 4 is located in the notch 12, so that the first fixing member 1 can avoid the ear 5. A first hole 13 is provided on the first fixing member 1, and the first hole 13 penetrates the first fixing member 1 from the bottom of the notch 12 in a direction perpendicular to the first plane 11. A thread is provided on the hole wall of the first hole 13, and the thread on the hole wall of the first hole 13 can cooperate with the thread on the connecting portion 31, so that the first fixing hole is connected to the connecting portion 31.

[0037] like Figure 4 As shown, the second fixing member 2 includes a main body 21 and a protrusion 22. The main body 21 is in a rectangular parallelepiped shape, and the protrusion 22 is in a cylindrical shape. The protrusion 22 and the main body 21 can be integrally formed. The main body 21 includes a second plane 211 facing the first fixing member 1, and the protrusion 22 protrudes from the second plane 211 in a direction toward the first fixing member 1. When the battery pack is hoisted using a hoisting tool, the second plane 211 fits with the lower surface of the part to be hoisted 4, and a placement groove is provided on the part to be hoisted 4. The protrusion 22 is located in the placement groove, thereby fixing the relative position of the part to be hoisted 4 and the second fixing member 2. The second fixing member 2 is provided with a second hole 23, which penetrates the protruding portion 22 and the main body 21 in a direction perpendicular to the second plane 211. The hole wall of the second hole 23 is provided with a thread, and the thread on the hole wall of the second hole 23 can cooperate with the thread on the connecting portion 31, so that the second hole 23 is connected to the connecting portion 31, and the thread on the hole wall of the first hole 13 is opposite to the thread on the hole wall of the second hole 23. In this way, the first fixing member 1 and the second fixing member 2 can be brought closer to or farther from each other by screwing the connecting member 3, thereby achieving the installation or fixation of the hoisting member 4.

[0038] Furthermore, if Figure 1and Figure 2 As shown, the orthographic projection of the protrusion 22 on the first plane 11 is located in the recess 12. When the battery pack is hoisted using a hoisting tool, the positions of the protrusion 22, the hanging ear 5 and the recess 12 correspond, and the connecting member 3 passes through the main body 21, the protrusion 22, the part to be hoisted 4, the hanging ear 5 and the first fixing member 1, ensuring that the relative positions of the first fixing member 1 and the second fixing member 2 and the part to be hoisted 4 are fixed to prevent the hanging ear 5 from being damaged.

[0039] When the battery pack is hoisted using the hoisting tool of the present application, the connector 3 applies force to the two surfaces of the hoisting component 4 through the first fixing component 1 and the second fixing component 2 respectively, and the hanging ear 5 is no longer subjected to force, thereby reducing the risk of damage to the hanging ear 5.

[0040] According to another aspect of the present application, a battery pack is provided, which includes a part to be hoisted 4 and the above-mentioned hoisting tooling. The battery pack has the same technical effect as the above-mentioned hoisting tooling, which will not be repeated here.

[0041] Furthermore, the battery pack also includes a box body and a hanging ear 5. The hoisting part 4 extends from the upper surface of the box body. The hoisting part 4 can be in a plate shape. A mounting hole is opened on the hoisting part 4. The hanging ear 5 is embedded in the mounting hole. The hanging ear 5 has a center hole, so that the connecting part 3 can pass through the hanging ear 5, the hoisting part 4, the first fixing part 1 and the second fixing part 2, thereby realizing the installation of the hoisting tooling.

[0042] In addition, a placement groove is provided on the part to be hoisted 4, and the placement groove is used to accommodate the protrusion 22 of the second fixing member 2. When the part to be hoisted 4 is arranged in the accommodation space 6, the protrusion 22 of the second fixing member 2 is fully extended into the placement groove of the part to be hoisted 4, so as to achieve relative fixation between the second fixing member 2 and the part to be hoisted 4.

[0043] When the battery pack is hoisted using the hoisting part 4, the hoisting part 4 is located in the accommodating space 6, and the two surfaces of the hoisting part 4 facing each other are respectively in contact with the first plane 11 of the first fixing part 1 and the second plane 211 of the second fixing part 2. The connecting part 3 applies force to the two surfaces of the hoisting part 4 through the first fixing part 1 and the second fixing part 2, respectively, and the hanging ear 5 is no longer subjected to force, thereby reducing the risk of damage to the hanging ear 5.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
