Technical Field

[0001] This utility model belongs to the field of hoisting tooling technology, specifically relating to a combined hoisting structure for lithium battery sheet metal modules. Background Technology

[0002] With the widespread application of lithium batteries in portable electronic devices, electric forklifts, electric vehicles, and energy storage systems, the design trend of lithium battery enclosures is towards smaller size and higher integration. To meet this demand, modular use of battery cells is becoming increasingly common. However, traditional lithium battery module designs typically require mounting holes on both sides for installation, resulting in larger enclosure space requirements and limiting further reduction in the size of lithium battery enclosures.

[0003] While existing hoisting methods can ensure the safe hoisting of lithium battery modules, they require a large external space during operation, resulting in a larger chassis size, low space utilization, and difficulty in installing lithium battery sheet metal modules in confined spaces. This also makes it difficult to effectively reduce the external size of the lithium battery chassis and affects the product's integration.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0032] like Figures 1-5 As shown, a combined hoisting structure for a lithium battery sheet metal module in one embodiment of this utility model includes a first rod 1. Since the sheet metal design on both sides of the lithium battery sheet metal module features hollowed-out reinforcing ribs, the first rod 1 is a cylindrical body with a diameter of 5-15mm as its main body to facilitate passage through the gaps in the sheet metal reinforcing ribs. A storage groove 102 is provided at the lower end of the first rod 1. A claw 3 matching the storage groove 102 is installed on the first rod 1. A first through hole 103 matching the storage groove 102 is provided at the lower end of the first rod 1. A pin structure 4 matching the first through hole 103 is installed on the first rod 1. A second through hole 301 matching the pin structure 4 is provided on the claw 3, and the second through hole 301 is eccentrically positioned.

[0033] The first rod 1 has a connecting platform 101, and the two ends of the pin structure 4 are located on the connecting platform 101, with the pin structure 4 situated within the outer diameter of the first rod 1. From a top-down view of the hoisting structure, the two ends of the pin structure 4 do not exceed the outer diameter of the first rod 1. This avoids the situation where the first rod 1 meets the specified dimensions, but hoisting is impossible due to one or both ends of the pin structure 4 exceeding the outer diameter of the first rod 1.

[0034] Specifically, such as Figures 1-5As shown, the chuck 3 adopts an irregular design with a protrusion at one end. The protrusion ensures that it is locked in the lifting hole of the sheet metal bracket and will not fall off during the lifting process. Because the axis of the chuck 3 is eccentrically designed and the weight of the chuck 3 is concentrated on one side, the chuck 3, which is originally stored in the first rod body 1, can automatically rotate out when passing through the lifting hole of the sheet metal module because there is no supporting surface, thus locking the sheet metal module when it is lifted.

[0035] like Figures 1-3 As shown, the pin structure 4 includes a shaft 5, which passes through the first through hole 103 and the second through hole 301 in sequence. The shaft 5 serves as the rotation shaft of the chuck 3. A groove 501 is provided on the shaft 5, and a retaining spring 6 that matches the groove 501 is installed on the shaft 5. The retaining spring 6 is engaged in the groove 501, ensuring that the shaft 5 can remain within the first through hole 103 and will not fall out of the first through hole 103. The pin structure 4 can also use bolts, nuts, or other methods to allow the chuck 3 to rotate in the storage groove 102.

[0036] The first rod 1 has a connecting assembly installed at its upper end, which allows it to connect with the lifting arm and the operator. The connecting assembly includes a handle 2 detachably mounted on the first rod 1. The operator moves the lithium battery sheet metal module by holding the handle 2 and lifting it. Specifically, a threaded post 7 is fixedly connected to the upper end of the first rod 1, and the handle 2 has a second threaded hole 201 that matches the threaded post 7. The threaded post 7 and the handle 2 are threaded together.

[0037] In order to allow the first rod 1 to adapt to more sizes of lithium battery sheet metal modules, such as Figures 6-10 As shown, a groove 104 is provided on the first rod 1, and a second rod 9 that matches the groove 104 is slidably connected to the first rod 1. The second rod 9 is slidably connected to the inside of the first rod 1 through the groove 104. A third threaded hole 901 is provided on the second rod 9, and multiple evenly distributed first threaded holes 106 are provided on the first rod 1. Nuts 8 that match the first threaded holes 106 are threadedly connected to the first rod 1. The nuts 8 pass through the first threaded holes 106 and are threadedly connected to the third threaded holes 901. That is, the third threaded hole 901 corresponds to the first threaded holes 106 at different positions and is fixed by the nuts 8, which can change the length of the first rod 1, so that the lifting structure can adapt to lithium battery sheet metal modules of different specifications.

[0038] like Figures 6-8 As shown, the first rod body 1 has a first receiving hole 107 that matches the first threaded hole 106. The outer diameter of the first receiving hole 107 is larger than the outer diameter of the first threaded hole 106, and one end of the nut 8 is received in the first receiving hole 107. This is to avoid the nut 8 being exposed as much as possible, which would cause the outer diameter of the first rod body 1 to expand and affect the normal hoisting of the first rod body 1.

[0039] Because of the presence of the second rod 9, the threaded post 7 is fixedly connected to the end of the second rod 9 away from the first rod 1.

[0040] like Figures 6-8 As shown, the inner wall of the groove 104 is provided with several inwardly protruding ribs 105. The ribs 105 can strengthen the first rod 1 and avoid affecting the load-bearing capacity of the first rod 1 as much as possible due to the opening of the groove 104.

[0041] like Figures 6-10 As shown, a protective sleeve 12 matching the slide groove 104 is fixedly connected to the first rod 1. The protective sleeve 12 is in contact with the outer wall of the second rod 9, and the protective sleeve 12 causes the first rod 1 and the second rod 9 to have an interference fit, that is, the second rod 9 cannot easily slide freely in the first rod 1. The first rod 1 has multiple sets of blind holes 108 matching the first receiving hole 107 on the inner wall of the slide groove 104. A protrusion 10 matching the blind hole 108 is fixedly connected to the second rod 9. When one of the first threaded holes 106 is aligned with the third threaded hole 901, the protrusion 10 is located in one of the blind holes 108. At the moment the protrusion 10 enters the blind hole 108, the operator can feel it by touching the second rod 9, thereby judging the positional matching of the first threaded hole 106 and the third threaded hole 901.

[0042] like Figures 7-9 As shown, a rubber ring 11 is fixedly connected to the lower end of the first rod 1. The rubber ring 11 prevents the first rod 1 from directly contacting the lithium battery sheet metal module, thereby reducing the possibility of the first rod 1 contacting the lithium battery sheet metal module and causing it to bump or knock.

[0043] like Figure 9 As shown, a third through hole 701 is provided on the threaded post 7. Since the handle 2 is replaceable, by disassembling the handle 2, a lifting ring can be threaded onto the threaded post 7, or a lifting device can be installed through the third through hole 701 to enable the use of a crane arm to lift the lithium battery sheet metal module. The handle 2 can be replaced according to the actual situation.

[0044] When using, such as Figures 4-5 As shown, the first rod 1 with the claw 3 is inserted into the hollow structure of the lithium battery sheet metal module, so that the outer wall of the claw 3 contacts the hollow structure. The claw 3 is blocked, so the claw 3 rotates into the storage slot 102. Until the claw 3 at the lower end of the first rod 1 passes through the hollow structure of the lithium battery sheet metal module, the claw 3 will automatically rotate out because its weight is concentrated on one side. When lifted, the claw 3 engages with the lithium battery sheet metal module. Then, the lithium battery sheet metal module can be hoisted by the operator holding the handle 2.

[0045] When it is necessary to adjust the length of the first rod 1, firstly, as follows: Figures 6-10 As shown, nut 8 needs to be loosened, and then the second rod 9 should slide in the groove 104 to confirm the combined length of the first rod 1 and the second rod 9. Feedback from the protrusion 10 entering the blind hole 108 indicates alignment between the protrusion 10 and the blind hole 108. Then, nut 8 is screwed into the corresponding first threaded hole 106, and then threaded into the third threaded hole 901, thus locking the first rod 1 and the second rod 9. It is worth noting that one end of nut 8 is completely located in the first receiving hole 107.

[0046] The hoisting structure of this utility model adopts a modular design, connected by bolts and pins to ensure convenient, safe and stable assembly. Since lithium battery sheet metal modules are mostly assembled manually, a threaded post 7 is provided at the end of the first rod 1 away from the claw 3. The handle 2 is mainly installed through the threaded post 7 for easy manual use, and can also be connected to lifting ring accessories by thread for machine hoisting.

[0047] This utility model controls the outer diameter of the first rod 1 to pass through the gap of the reinforcing ribs of the sheet metal module. Through the irregular design of the claw 3, the claw 3 can automatically unscrew when passing through the lifting hole of the sheet metal module. Through the convenient threaded connection, the entire structure can be switched between the handle 2 which is convenient for manual use or the lifting ring which is convenient for machine lifting, so as to achieve the purpose of lifting and installing lithium battery sheet metal modules in the narrow gap of the chassis.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
