[0033] In order to make the objectives, technical solutions and advantages of the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0034] Aiming at the technical problems of time-consuming, laborious and low hoisting efficiency existing in the existing hoisting tooling for the liquid-cooled bottom plate of the battery pack, the present utility model provides a hoisting tooling for the liquid-cooled bottom plate of the battery pack. The clamping size of the tooling can be changed by its own weight, and it is not necessary for the operator to fix the tooling and the hoisting object on both sides respectively, thus achieving the purpose of improving the hoisting efficiency.

[0035] It should be noted that the hoisting tooling described in the present utility model is applicable to but not limited to the liquid-cooled bottom plate of the battery pack. For the convenience of description, only the application of the hoisting tooling to the liquid-cooled bottom plate of the battery pack is taken as an example for description, and the principle of the hoisting tooling applied to other types of hoisting objects is essentially the same as that applied to the liquid-cooled bottom plate of the battery pack, which will not be elaborated one by one here.

[0036] As Figure 1 shown, this embodiment relates to a hoisting tooling for the liquid-cooled bottom plate of the battery pack, including a first lifting arm 100, a second lifting arm 200, a first clamping mechanism 300 and a second clamping mechanism 400. The first lifting arm 100 and the second lifting arm 200 are arranged horizontally and stacked up and down, with the first lifting arm 100 on the upper side and the second lifting arm 200 on the lower side. One end of the first lifting arm 100 and the second lifting arm 200 is hinged so that the other ends of the first lifting arm 100 and the second lifting arm 200 can be opened and closed under the action of an external force; the first clamping mechanism 300 and the second clamping mechanism 400 are respectively arranged at two opposite ends of the first lifting arm 100 and the second lifting arm 200. In this way, the distance between the two will increase or decrease as the first lifting arm 100 and the second lifting arm 200 are opened and closed.

[0037] When using the tooling provided in this embodiment to hoist the liquid-cooled bottom plate of the battery pack, the first clamping mechanism 300 and the second clamping mechanism 400 can be directly placed on both sides of the liquid-cooled bottom plate. Then, when the first lifting arm 100 is lifted upward, the first lifting arm 100 and the second lifting arm 200 will open around their hinge points, and the distance between the first clamping mechanism 300 and the second clamping mechanism 400 will become shorter, so that the liquid-cooled bottom plate can be clamped. Compared with the existing tooling, the clamping process of this embodiment does not require the operator to fix the tooling and the liquid-cooled bottom plate on both sides respectively. The clamping process is very convenient, which can save the hoisting time and greatly improve the hoisting efficiency.

[0038] In one of the embodiments, as Figure 2As shown, the first lifting arm 100 includes a first horizontal arm 110, a first vertical arm 120, and a first hinge seat 130. The first vertical arm 120 is vertically fixed to one end of the first horizontal arm 110. One end of the first hinge seat 130 is fixedly connected to the first vertical arm 120 and is located below the first horizontal arm 110. The other end of the first hinge seat 130 is hinged to the second lifting arm 200. Among them, the first clamping mechanism 300 is disposed on the first vertical arm 120.

[0039] In one embodiment, as Figure 3 shown, the second lifting arm 200 includes a second horizontal arm 210 and a second vertical arm 220. One end of the second horizontal arm 210 has a hinge hole 211. The hinge hole 211 is hinged to the first hinge seat 130 through a pin shaft. The second vertical arm 220 is fixed to the other end of the second horizontal arm 210. Among them, the second clamping mechanism 400 is disposed on the second vertical arm 220.

[0040] In one embodiment, as Figure 3 shown, a limiting hole 212 is further formed on one side of the second horizontal arm 210 having the hinge hole 211. A limiting pin 213 is disposed in the limiting hole 212 to control the opening and closing angle between the first lifting arm 100 and the second lifting arm 200.

[0041] In one embodiment, the first clamping mechanism 300 and the second clamping mechanism 400 are respectively hinged to the first vertical arm 120 and the second vertical arm 220. The purpose of such a setting is to facilitate the first clamping mechanism 300 and the second clamping mechanism 400 to be more easily clamped on both sides of the liquid-cooled bottom plate. When the first clamping mechanism 300 and the second clamping mechanism 400 respectively contact both sides of the liquid-cooled bottom plate, since they are hinged to the first vertical arm 120 and the second vertical arm 220, the first clamping mechanism 300 and the second clamping mechanism 400 can be turned outwards, and the distance between them is greater than the distance between both sides of the liquid-cooled bottom plate, which is convenient for clamping.

[0042] In one embodiment, as Figure 4 shown, a first connection hole 121 is formed at one end of the first vertical arm 120 away from the first horizontal arm 110. The first clamping mechanism 300 includes a second hinge seat 310. The first connection hole 121 is hinged to the second hinge seat 310 through a pin shaft.

[0043] In one embodiment, as Figure 4As shown, the first clamping mechanism 300 further includes a first support plate 320 and a first silica gel pad 330. On one side of the first support plate 320 close to the first vertical arm 120, a second hinge seat 310 is fixed. The first support plate 320 is hinged to the first vertical arm 120 through the second hinge seat 310. The first silica gel pad 330 is installed on the other side of the first support plate 320 and can protect the liquid-cooled bottom plate from damage.

[0044] In one embodiment, as Figure 5 shown, at one end of the second vertical arm 220 away from the second horizontal arm 210, a second connection hole 221 is formed. The second clamping mechanism 400 includes a third hinge seat 410. The second connection hole 221 is hinged to the third hinge seat 410 through a pin shaft.

[0045] In one embodiment, as Figure 5 shown, the second clamping mechanism 400 further includes a second support plate 420 and a second silica gel pad 430. On one side of the second support plate 420 close to the second vertical arm 220, the third hinge seat 410 is fixed. The second support plate 420 is hinged to the second vertical arm 220 through the third hinge seat 410. The second silica gel pad 430 is installed on the other side of the second support plate 420.

[0046] In one embodiment, a plurality of threaded holes 111 are formed on the upper surface of the first horizontal arm 110. The tooling further includes a lifting ring 500. The lifting ring 500 is threadedly connected to different threaded holes 111 to find a suitable lifting point.

[0047] As Figure 6 shown, when the lifting tooling for the liquid-cooled bottom plate of the battery pack provided by the present utility model is in use, it is suspended above the liquid-cooled bottom plate through the lifting ring 500. The first clamping mechanism 300 and the second clamping mechanism 400 turn outwardly in the natural state, and the distance between them is greater than the distance between both sides of the liquid-cooled bottom plate. It is easy to clamp the first clamping mechanism 300 and the second clamping mechanism 400 on both sides of the liquid-cooled bottom plate. Then, the first lifting arm 100 is lifted upward, and the second lifting arm 200 opens and closes with the first lifting arm 100, so that the distance between the first clamping mechanism 300 and the second clamping mechanism 400 becomes smaller, and the liquid-cooled bottom plate can be clamped. Finally, it can be lifted through the lifting ring 500.

[0048] The above specific embodiments of the present utility model do not constitute a limitation to the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model should be included in the protection scope of the claims of the present utility model.
