These battery packs are usually composed of multiple battery cells to provide enough power to drive the forklift's electric drive system. Forklift battery packs are usually installed at the bottom of the forklift and can be a single large battery pack or a combination of multiple smaller battery cells. These battery packs are usually composed of battery cells such as high-capacity lead-acid batteries, nickel-metal hydride batteries or lithium-ion batteries.

[0003] For example, a Chinese patent publication numbered CN220439783U discloses a battery mounting structure for an electric forklift. The battery mounting structure for an electric forklift provided in the cited document has the advantages of being simple in structure, easy to install, and having a concise layout.

[0004] While the cited patent allows for rapid installation of the battery pack, it still has certain limitations.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example

[0025] Depend on Figure 1-4 Provided is a protective device comprising a forklift battery pack body 1;

[0026] The bottom of the forklift battery pack body 1 is provided with four sets of shock-absorbing protection components 2 in a rectangular shape;

[0027] Each set of shock absorption protection components 2 includes four rubber bases 21 arranged in a rectangular shape at the bottom of the forklift battery pack body 1. A plurality of positioning shafts 23 are provided on each of the four rubber bases 21. A bearing seat 24 is provided outside the plurality of positioning shafts 23. A plurality of arched plates 26 are vertically provided on the upper end surface of the bearing seat 24.

[0028] The shock-absorbing protection component 2 also includes an energy-absorbing seat 210 arranged on the positioning plate 22. An inner tube 211 is arranged in the energy-absorbing seat 210. A core column 212 is vertically arranged in the inner tube 211. The inner tube 211 is filled with a plurality of energy-absorbing cottons 213, and the energy-absorbing cottons 213 surround the core column 212.

[0029] In this embodiment, in actual use, through the connection assembly between the arch plate 26 and the connecting plate 27 and the energy-absorbing column 28 in the shock-absorbing protection component 2, when the supporting seat 24 is affected by vibration, the forklift battery pack body 1 is installed and pressed down on the connecting seat 29, so that the arch plate 26 will be deformed, thereby absorbing the generated vibration. At the same time, with the setting of the energy-absorbing column 28, it can finally absorb the vibration and impact during the driving of the forklift, thereby protecting the forklift battery pack body 1 from damage.

[0030] Furthermore, when the forklift battery pack body 1 is subjected to bumps in the use scenario, the rubber base 21 and the positioning plate 22 provided at this time can initially absorb the bump vibrations suffered by the forklift battery pack body 1, and at the same time, the core column 212 and the energy-absorbing cotton 213 in the energy-absorbing seat 210 can absorb the vibration force again, thereby reducing the vibration and impact force transmitted to the forklift battery pack body 1, thereby protecting the forklift battery pack body 1 from damage.

[0031] Specifically, refer to Figure 2-3 The outer portion of the inner cylinder 211 is provided with a pressing cylinder 214 , and the pressing cylinder 214 is arranged at the bottom of the supporting seat 24 and a distance is formed between the pressing cylinder 214 and the supporting seat 24 .

[0032] In this embodiment, during use, the set pressing cylinder 214 can be used to surround the core column 212 and the energy-absorbing cotton 213, thereby preventing the energy-absorbing cotton 213 and the energy-absorbing cotton 213 from being damaged by the outside. In a preferred embodiment, the set pressing cylinder 214 can be screwed onto the outside of the inner cylinder 211 by means of a threaded connection, thereby achieving stable installation of the pressing cylinder 214. At the same time, the distance between the set pressing cylinder 214 and the supporting seat 24 can allow the supporting seat 24 to slide on the outside of the positioning shaft 23.

[0033] Specifically, refer to Figure 2-3 A connecting plate 27 is commonly supported on the top of the plurality of arched plates 26 , an energy absorbing column 28 is provided on the upper portion of the connecting plate 27 , and a connecting seat 29 is provided on the energy absorbing column 28 .

[0034] In this embodiment, through the connection between the energy-absorbing column 28 and the connecting seat 29, during use, the energy-absorbing column 28 can cooperate with the connecting plate 27 to absorb the vibration force, thereby reducing the hard vibration transmitted to the forklift battery pack body 1. In a preferred embodiment, the energy-absorbing column 28 can also adopt a hollow structure.

[0035] Specifically, refer to Figure 1-3 A plurality of threaded holes are provided on the connecting seat 29 . The connecting seat 29 is arranged at the bottom of the forklift battery pack body 1 and is detachably mounted to the forklift battery pack body 1 through bolts.

[0036] In this embodiment, the connection seat 29 is provided to be connected to the bottom of the forklift battery pack body 1. In a preferred embodiment, Figure 1 As shown in FIG, the connection seat 29 is stably connected to the forklift battery pack body 1 by using bolts.

[0037] Specifically, refer to Figure 2-3 A compression spring 25 is sleeved on the outside of each positioning shaft 23 . The bottom of the compression spring 25 is connected to the positioning plate 22 , and the top of the compression spring 25 is against the bottom surface of the bearing seat 24 .

[0038] In this embodiment, when the forklift battery pack body 1 is subjected to external bumps, the sliding assembly between the supporting seat 24 and the positioning shaft 23 allows the supporting seat 24 to slide linearly on the positioning shaft 23, and at the same time, the compression spring 25 is compressed by the supporting seat 24, so that the compression spring 25 can be deformed, thereby reducing the hard vibration transmitted to the bow plate 26, thereby reducing the vibration damage transmitted to the forklift battery pack body 1; the protection of the forklift battery pack body 1 by the provided shock-absorbing protection component 2 can reduce the vibration and impact on the forklift battery pack body 1 during the actual assembly and use of the forklift battery pack body 1, thereby helping to improve its safety and reduce the safety risks caused by vibration;

[0039] Furthermore, by reducing vibration and impact, the maintenance cost of the forklift battery pack body 1 can be reduced, so that the forklift battery pack body 1 is relatively less likely to be damaged.

[0040] Specifically, refer to Figure 2-3 A nut is provided on the top of the positioning shaft 23, and the nut is used to limit the sliding stroke of the bearing seat 24.

[0041] In this embodiment, the nut member provided on the top of the positioning shaft 23 can be used to prevent the bearing seat 24 from slipping outside the positioning shaft 23 , thereby limiting the bearing seat 24 from sliding on the positioning shaft 23 all the time.

[0042] The protective device of this utility model:

[0043] Step 1: In actual use, the user assembles multiple groups of shock-absorbing protection components 2 on the bottom of the forklift battery pack body 1 using bolts. After the shock-absorbing protection components 2 are assembled, when the forklift battery pack body 1 is bumped during use, the rubber base 21 and positioning plate 22 can initially absorb the bump vibration of the forklift battery pack body 1 and transmit it to the energy-absorbing seat 210. At this time, the core column 212 and energy-absorbing cotton 213 in the energy-absorbing seat 210 can further absorb the vibration force, thereby reducing the vibration transmitted to the forklift battery pack body 1;

[0044] Step 2: When the forklift battery pack body 1 is subjected to external bumps, the sliding assembly between the supporting base 24 and the positioning shaft 23 allows the supporting base 24 to slide linearly on the positioning shaft 23. At the same time, the supporting base 24 compresses the compression spring 25, causing the compression spring 25 to deform, thereby reducing the hard vibration transmitted to the bow plate 26 and reducing the vibration damage transmitted to the forklift battery pack body 1.

[0045] Step 3: Through the connection and assembly between the provided bow plate 26 and the connecting plate 27 and the energy-absorbing column 28, in actual use, when the supporting seat 24 is affected by vibration, the forklift battery pack body 1 is installed and pressed down on the connecting seat 29, so that the provided bow plate 26 will be deformed, thereby absorbing the generated vibration. At the same time, in conjunction with the setting of the energy-absorbing column 28, it can eventually absorb the vibration and impact during the driving of the forklift, thereby protecting the forklift battery pack body 1 from damage.

[0046] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
