Description

Technical Field

[0001] The utility model relates to the technical field of battery packs, in particular to a lifting tool. Background Art

[0002] With the rapid development of new energy, demand for industrial and commercial storage and containers is increasing. Major companies are continuously implementing cost-reduction initiatives to enhance their competitiveness in the new energy market. Traditional battery packs consist of five components: an upper housing, a lower housing, modules, thermal management, and electrical components. The overall lifting and mounting point is typically located at the bottom of the lower housing. A lifting eye is screwed into the lower housing's mounting hole, and the battery pack is hoisted directly with a sling for transport.

[0003] At present, for cost reduction considerations, the lower shell is made into a split structure of cold plate and side beam, and the aluminum profile side beam is thinned, and the upper shell of the whole pack is eliminated to make a battery pack without a top shell. For this type of battery pack without a top shell, the lifting holes are located on the side of the battery pack, and the battery pack needs to be stacked in clusters of a certain height. The existing battery pack lifting tooling uses a lifting ring and a lifting rope for lifting, which requires a relatively large lifting space. After the battery pack is lifted, there is a risk of interference between the lifting rope and the module, damaging the module, uneven force, and the entire pack falling, which is not conducive to improving the lifting stability and lifting safety of the battery pack.

[0037] Example 1

[0038] This embodiment relates to a lifting fixture, which aims to improve the stability and safety of the battery pack lifting process by optimizing the structure of the lifting fixture.

[0039] In terms of overall structure, Figures 1 to 3 As shown, the lifting tool in this embodiment is used to lift the battery pack, including a frame 1, a mounting portion 2 provided on the frame 1 and a connecting portion 3 provided on the mounting portion 2.

[0040] Among them, the frame 1 includes a beam 101, a hanging ring 102 arranged on the beam 101, and a connecting plate 103 arranged on both sides of the beam 101. The mounting part 2 is arranged on the connecting plate 103. The connecting part 3 includes a base plate 301 arranged on the mounting part 2, and a connecting pin 302 arranged on the base plate 301.

[0041] When the connecting portion 3 is connected to the battery pack, the connecting pin 302 can be operated to pass through the hanging hole on the side beam of the battery pack to constrain the battery pack on the frame 1.

[0042] As configured above, the lifting fixture in this embodiment can constrain the battery pack on the frame 1 through the setting of the connecting pin 302, and the setting of the lifting ring 102 on the frame 1 facilitates the lifting of the battery pack in cooperation with an external lifting device. The setting of the crossbeam 101 and the connecting plate 103 improves the connection stability of the mounting part 2, and the setting of the mounting part 2 improves the lifting stability. The cooperation of various structures effectively constrains the battery pack on the frame 1, improves the stability of the entire lifting structure, and thus helps to improve the stability and safety of the battery pack lifting.

[0043] Specifically, in this embodiment, as an exemplary structure, combined with Figure 1 and Figure 2 As shown, in order to better improve the structural strength of the frame 1, a reinforcement plate is further provided on the frame 1 in this embodiment. The reinforcement plate is provided at the connection between the beam 101 and the connecting plate 103. Through the provision of the reinforcement plate, the connection strength between the beam 101 and the connecting plate 103 is further improved, thereby improving the structural strength of the frame 1 and facilitating the improvement of the stability of the lifting.

[0044] In more detail, the frame 1 in this embodiment can be made of aluminum profiles, for example. The beam 101 and the connecting plate 103 are both arranged in a rectangular plate shape. The beam 101 is clamped between the two connecting plates 103 and fixed to the connecting plates 103 by bolts. The hanging ring 102 is arranged in the middle of the beam 101.

[0045] In order to better improve the connection strength between the beam 101 and the connecting plate 103, a reinforcing plate is provided on the frame 1 in this embodiment. The reinforcing plate is arranged at the connection between the beam 101 and the connecting plate 103. Through the setting of the reinforcing plate, the connection strength between the beam 101 and the connecting plate 103 is further improved, thereby improving the structural strength of the frame 1, which is conducive to improving the stability of lifting.

[0046] In order to facilitate the removal of the frame 1, Figure 1 and Figure 2 As shown, in this embodiment, the crossbeam 101 is provided with a handle 104. The handle 104 includes through holes at both ends of the crossbeam 101. The provision of the handle 104 facilitates the removal and installation of the lifting tool, and the structure is simple, which facilitates the design and implementation. To further facilitate the removal, the inner wall of the through hole can be rounded or coated with an anti-slip layer to enhance the grip of the handle 104 and make it more convenient to remove.

[0047] The mounting portion 2 in this embodiment can disperse the stress during lifting and ensure the structural strength of the frame 1. Specifically, the mounting portion 2 in this embodiment includes a mounting plate 201 arranged on the connecting plate 103, and the base plate 301 is arranged on the outside of the mounting plate 201, so that the mounting portion 2 includes the mounting plate 201, which is beneficial to the stress dispersion during lifting, and the structure is simple, which is conducive to design implementation.

[0048] In more detail, the mounting plate 201 in this embodiment is arranged in a trapezoidal plate shape, one end of the connecting plate 103 is stacked on the middle part of the mounting plate 201, and is fixedly connected to the mounting plate 201 by bolts. The shorter bottom edge of the mounting plate 201 is arranged toward the beam 101, which can better disperse the stress of the connection between the connecting part 3 and the battery pack, thereby improving the stability of the lifting tooling.

[0049] The connection portion 3 in this embodiment facilitates the lifting of battery packs without a top housing. By operating the connection pin 302 to engage the lifting holes on the battery pack side beams, the stability and safety of the battery pack during lifting can be ensured. The number of connection portions 3 in this embodiment can be four, eight, or twelve, as long as the battery pack can be stably lifted.

[0050] Specifically, combined with Figures 1 to 3 As shown, the connecting part 3 in this embodiment includes a base plate 301 and a connecting pin 302 arranged on the base plate 301, the end of the connecting pin 302 is hinged with an arc-shaped connecting rod 303, and the arc-shaped connecting rod 303 is hinged with a handle 304. One end of the arc-shaped connecting rod 303 is hinged on the connecting pin 302, and the other end is hinged on the handle 304, and the handle 304 is also hinged on the base plate 301. By operating the handle 304, the connecting pin 302 can be pushed into or out of the lifting hole of the battery pack through the arc-shaped connecting rod 303. The arrangement of the arc-shaped connecting rod 303 and the handle 304 facilitates the operation of the connecting pin 302, has a simple structure, and is conducive to design implementation.

[0051] It is worth mentioning that the handle 304 in this embodiment can be further equipped with a locking structure when in use. The setting of the locking structure can provide double protection so as to better prevent the connecting pin 302 from falling out of the lifting hole. The specific composition of the locking structure can be, for example, referred to the locking structure for locking the handle 304 in the prior art.

[0052] In order to better adapt to different sizes of lifting holes, combined Figure 3 As shown, an extension rod 305 can be further provided between the connecting pin 302 and the arc-shaped connecting rod 303 in this embodiment. When the extension rod 305 is provided, one end of the extension rod 305 is hinged to the end of the arc-shaped connecting rod 303, and the other end of the extension rod 305 is screwed to the end of the connecting pin 302. At this time, the connecting pin 302 is not hinged to the arc-shaped connecting rod 303. By adjusting the screw connection length of the extension rod 305 and the connecting pin 302, the insertion depth of the connecting pin 302 and the lifting hole can be adjusted. By setting the extension rod 305, it is convenient to adjust the connection length between the connecting pin 302 and the battery pack, which is conducive to adapting to lifting holes of different sizes.

[0053] In more detail, by setting the extension rod 305, the connection depth between the connecting pin 302 and the battery pack lifting hole can be adjusted, which can prevent the connecting pin 302 from damaging the structure inside the battery pack, such as mica paper, and avoid usage problems caused by damage to the battery pack structure, which is beneficial to ensuring the safety of the battery pack after lifting.

[0054] In order to better position the lifting holes of the battery pack side beams, the connecting part 3 in this embodiment also includes a positioning block 306 provided on the inner side of the mounting plate 201. The positioning block 306 is provided with a positioning groove. When the connecting part 3 is connected to the battery pack, the side beams of the battery pack are located in the positioning groove. The setting of the positioning block 306 facilitates the positioning of the lifting holes on the battery pack by the lifting tool. At the same time, the setting of the positioning block 306, in conjunction with the connecting pin 302, can better constrain the battery pack on the frame 1. The structure is simple and convenient for design implementation.

[0055] When using the lifting tool of this embodiment, first pick up the lifting tool above the battery pack through the handheld part 104, locate the lifting hole of the battery pack through the positioning block 306, operate the handle 304, insert the connecting pin 302 into the lifting hole of the battery pack, and use the hook of the external lifting device to cooperate with the lifting ring 102 on the beam 101 to lift the battery pack to the predetermined position.

[0056] The lifting fixture in this embodiment improves the structural stability of the overall structure through the structural design of the crossbeam 101, the connecting plate 103 and the reinforcing plate. The setting of the mounting plate 201 disperses the force exerted by the battery pack on the lifting fixture, thereby improving the structural strength of the lifting fixture. The setting of the connecting part 3 effectively constrains the battery pack on the frame 1, thereby enhancing the stability and safety of the entire structure, preventing the battery pack from shaking or falling off during the lifting process, and helping to improve the stability and safety of the battery pack lifting.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
