For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] As described in the background technology, the battery pack of new energy vehicles often needs to be transported multiple times during the assembly process, and currently it is usually operated by lifting tools. Specifically, the existing battery pack lifting tools usually use ordinary horn hooks or eye hooks, etc., which are directly hooked on the lifting point installation holes of the battery pack, and then transported by equipment such as cranes.

[0032] However, the inventors have discovered that the use of these hooks often generates extrusion pressure around the battery pack's hanging point mounting holes, which may cause damage to the paint surface at the very least, and severe extrusion pressure may cause structural damage; especially for high-capacity and high-energy-density battery packs, which usually use aluminum profile shells with low material hardness and large mass of the battery pack itself; the lateral extrusion pressure generated by these hooks around the battery pack's hanging point mounting holes may cause cracking and damage to the thin wall of the outer profile.

[0033] Based on this, please refer to Figure 1-Figure 3 The embodiment of the utility model provides a battery pack hook 100, which can effectively improve the above-mentioned technical problems, that is, it can avoid the extrusion damage of the non-stress-bearing surface outside the hanging point of the battery pack 200, and improve the overall structural performance of the battery pack 200. The battery pack hook 100 will be described in detail below.

[0034] Please refer to Figure 1 , Figure 1 A schematic diagram of the hoisting of the battery pack 200 provided in this embodiment, combined with Figure 1 The battery pack 200 is provided with a lifting point steel sleeve 210. During lifting, the lifting point steel sleeve 210 cooperates with the battery pack hook 100 and is connected to the battery pack hook 100 through a lifting rope 300, so that the battery pack 200 is lifted as a whole, and then other lifting equipment such as a crane cooperates with the lifting rope 300 to realize operations such as the transportation of the battery pack 200.

[0035] Specifically, please refer to Figure 2 and Figure 3 , Figure 2 for Figure 1 A partial enlarged view of the middle A. Figure 3 The schematic diagram of the structure of the battery pack hook 100 provided in this embodiment is combined with Figure 2 and Figure 3 The battery pack hook 100 includes a hanging body 10 and a hook body 20. The hook body 20 includes a support column 21 and a support platform 22. The support column 21, the support platform 22 and the hanging body 10 are connected in sequence. The support column 21 is used to pass through the hanging point steel sleeve 210 of the battery pack 200 and abut against the inner wall of the hanging point steel sleeve 210. The support platform 22 is used to abut against the bottom of the hanging point steel sleeve 210. By the support column 21 abutting and receiving force against the inner wall of the hanging point steel sleeve 210, and the support platform 22 abutting and receiving force against the bottom of the hanging point steel sleeve 210, the lateral peripheral force generated by the conventional hook can be changed into axial steel sleeve force, thereby changing the force direction of the hook and the battery pack 200 during hoisting, avoiding the extrusion damage of the non-stress surface of the hanging point periphery of the battery pack 200, and thereby improving the overall structural performance of the battery pack 200.

[0036] It should be noted that in this embodiment, the support column 21 and the support platform 22 are both shaped like a cylinder. At this time, the diameter of the support column 21 will be smaller than the diameter of the support platform 22, so that after the support column 21 passes through the hanging point steel sleeve 210, the support platform 22 will abut against the bottom of the hanging point steel sleeve 210, thereby realizing axial force.

[0037] Furthermore, in this embodiment, the support column 21 and the support platform 22 are coaxially arranged, which can ensure that the support column 21 and the support platform 22 are more evenly stressed when cooperating with the lifting point steel sleeve 210, further improving the stability during the lifting process and further reducing damage to the battery pack 200 shell.

[0038] In the process of using the battery pack hook 100 to hoist the battery pack 200, in order to prevent the hook body 20 from being separated from the lifting point steel sleeve 210, in this embodiment, an anti-drop hole 211 is opened on the support column 21, and the anti-drop hole 211 is used to cooperate with the bayonet pin to prevent the support column 21 from being dropped when the support column 21 is inserted into the lifting point steel sleeve 210. That is, when the battery pack hook 100 and the battery pack 200 are installed, the support column 21 is first passed through the lifting point steel sleeve 210, and then the bayonet pin is passed through the anti-drop hole 211; in this way, even if the support column 21 is separated from the lifting point steel sleeve 210, the bayonet pin will be stuck by contacting with the top of the lifting point steel sleeve 210, thereby preventing the support column 21 from being dropped, thereby improving the safety of the battery pack 200 during the hoisting process.

[0039] It should be noted that in the present embodiment, the number of the anti-drop hole 211 is one; of course, in some other embodiments, in order to improve the adaptability of the battery pack hook 100, the number of the anti-drop hole 211 can also be multiple, and the multiple anti-drop holes 211 are arranged at intervals along the axial direction of the support column 21, and the bayonet is used to cooperate with any anti-drop hole 211 for anti-drop fixation. In this way, when the sizes of the hanging point steel sleeves 210 of different battery packs 200 are different, the same battery pack hook 100 can also be used for lifting; that is, after the support column 21 passes through the hanging point steel sleeve 210, the bayonet can be used to cooperate with the anti-drop hole 211 of the part of the support column 21 that extends out of the hanging point steel sleeve 210, thereby preventing the situation where the height of the hanging point steel sleeve 210 is too large and the anti-drop hole 211 is located on the inner wall of the hanging point steel sleeve 210 and cannot be exposed, thereby improving the adaptability of the battery pack hook 100. In addition, the portion of the support column 21 extending out of the hanging point steel sleeve 210 may also have a plurality of anti-drop holes 211 , which can further improve the assembly flexibility of the battery pack hook 100 .

[0040] Please continue to combine Figure 3 In order to improve the convenience of installing the support column 21, in this embodiment, the support column 21 has a guide portion 212 at one end away from the support platform 22. The setting of the guide portion 212 can play a guiding role, which facilitates the installation of the battery pack hook 100.

[0041] It should be noted that, in this embodiment, the guide portion 212 is conical in shape, and such a smooth outer surface can facilitate the installation of the support column 21. Of course, in other embodiments, the guide portion 212 can also be a truncated cone, a prism, or other shapes, as long as it can play a guiding role.

[0042] Combination Figure 3 Specifically, the lifting body 10 includes a first connecting part 11, a second connecting part 12 and a third connecting part 13 which are connected in sequence. The first connecting part 11 is connected to the support platform 22, and the third connecting part 13 is spaced apart from the support column 21 and the support platform 22, and the third connecting part 13 is used to connect to the lifting rope 300.

[0043] The spacing between the third connection part 13 and the support column 21 and the support platform 22 can facilitate the installation of the support column 21 and the support platform 22 on the suspension point steel sleeve 210 and avoid interference between the third connection part 13 and the suspension point steel sleeve 210 .

[0044] Furthermore, in this embodiment, the support column 21, the support platform 22 and the first connection portion 11 are coaxially arranged, the first connection portion 11 and the second connection portion 12 are vertically arranged, and the third connection portion 13 and the second connection portion 12 are vertically arranged. Figure 3As shown, by setting the second connecting portion 12 perpendicular to both the first connecting portion 11 and the third connecting portion 13 simultaneously, it can be seen that both the support column 21 and the support platform 22 are parallel to the third connecting portion 13. In this way, a structure similar to a "凵" shape can be formed as a whole. For the battery pack hook 100 with such a structure, it can better cooperate with the lifting point steel sleeve 210 in terms of force, making the force between the battery pack hook 100, the battery pack 200, and the lifting rope 300 more uniform during the lifting process, and further improving the lifting stability.

[0045] Please refer to Figure 1 and Figure 3 In order to facilitate the connection and cooperation between the battery pack hook 100 and the lifting rope 300, in this embodiment, the hanging body 10 further includes a fourth connecting portion 14. The fourth connecting portion 14 is connected to the end of the third connecting portion 13 away from the second connecting portion 12, and the included angle B between the fourth connecting portion 14 and the third connecting portion 13 is an obtuse angle. The fourth connecting portion 14 is used to connect with the lifting rope 300.

[0046] As Figure 1 shown, in this embodiment, four battery pack hooks 100 are provided and are in one-to-one correspondence with four lifting ropes 300. Then, the four lifting ropes 300 converge to a point for connection, and through the cooperation of other lifting equipment such as a crane, the transfer of the battery pack 200 is realized. It is easy to understand that by setting the included angle B between the fourth connecting portion 14 and the third connecting portion 13 to be an obtuse angle, when the fourth connecting portion 14 is assembled with the lifting rope 300, the extending direction of the fourth connecting portion 14 and the extending direction of the lifting rope 300 are on the same straight line, thereby further improving the force balance and force uniformity during the installation and lifting process, and further reducing the damage to the battery pack 200 during the lifting process.

[0047] In addition, in order to facilitate the connection between the fourth connecting portion 14 and the lifting rope 300, in this embodiment, a hanging hole 141 is provided at the end of the fourth connecting portion 14 away from the third connecting portion 13. The hanging hole 141 is used to cooperate with the lifting rope 300.

[0048] In summary, the embodiment of the present invention provides a battery pack hook 100. The battery pack hook 100 includes a hanging body 10 and a hook body 20. The hook body 20 includes a support column 21 and a support platform 22. The support column 21, the support platform 22, and the hanging body 10 are connected in sequence; the support column 21 is used to pass through the lifting point steel sleeve 210 of the battery pack 200 and abut against the inner wall of the lifting point steel sleeve 210; the support platform 22 is used to abut against the bottom of the lifting point steel sleeve 210.

[0049] That is to say, by the support column 21 abutting and receiving force against the inner wall of the lifting point steel sleeve 210, and the support platform 22 abutting and receiving force against the bottom of the lifting point steel sleeve 210, the lateral peripheral force generated by the conventional lifting hook can be converted into axial steel sleeve force, thereby changing the force direction of the lifting hook and the battery pack 200 during lifting, avoiding extrusion damage to the non-stressed surface outside the lifting point of the battery pack 200, and thereby improving the overall structural performance of the battery pack 200.

[0050] The above description is only a specific embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
