Description

Technical Field

[0001] This application relates to the field of lithium battery pack technology, and in particular to a forklift lithium battery pack. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, the processing, storage and use of lithium metal require very high environmental standards.

[0003] Lithium batteries have a wide range of applications, including in the production and processing of industrial vehicles. They are widely used in the power units of industrial vehicles, such as electric forklifts. However, due to the influence of the workplace and surrounding environment, lithium batteries are prone to shaking and collisions, which can damage them, affect their use, and make them inconvenient for users. Utility Model Content

[0004] To address the problem that existing forklift lithium battery packs are prone to shaking and collisions in forklift workplaces, making them susceptible to damage and affecting their usability, thus causing inconvenience for users, this application provides a forklift lithium battery pack.

[0005] The forklift lithium battery pack provided in this application adopts the following technical solution:

[0006] A forklift lithium battery pack includes a battery housing, a battery pack placed inside the battery housing, and a sealing cover disposed on the top of the battery housing. A support assembly is disposed at the bottom of the battery housing, and the battery pack is placed on top of the support assembly. Protective components that contact the battery pack are disposed on the four side walls of the battery housing. Multiple sets of limiting rods are symmetrically disposed on both sides of the protective components. One end of each limiting rod is fixedly connected to the inner wall of the battery housing, and a sleeve is slidably fitted onto the outer side of the other end. A first spring fixedly connected to the limiting rod is installed inside the sleeve, and a buffer block that contacts the battery pack is installed on the outer side of the sleeve.

[0007] Preferably, the support assembly includes a support base disposed at the bottom of the battery box, and the upper surface of the support base is sequentially provided with a first foam board, a first sponge pad, a second foam board, a fixing plate and a third foam board, and the battery pack is placed on top of the third foam board.

[0008] Preferably, multiple sets of buffer mechanisms are symmetrically arranged between the fixed plate and the support base. Each buffer mechanism includes a damping rod installed between the fixed plate and the support base, and a second spring is sleeved on the outside of the damping rod.

[0009] Preferably, the protective component includes an anti-collision pad installed on the inner wall of the battery box and an anti-collision block installed on the outer side of the anti-collision pad. An anti-collision airbag is embedded inside the anti-collision block, and a wear-resistant layer is provided on the outer surface of the anti-collision airbag that contacts the battery pack.

[0010] Preferably, the buffer block, anti-collision pad, and wear-resistant layer are all made of rubber.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This forklift lithium battery pack uses protective components to buffer and prevent collisions inside the battery box during forklift operation. When the battery pack shakes and hits the buffer block, it causes the sleeve to slide outside the limit rod and compress the first spring, further offsetting the impact force. By setting a support component at the bottom, the movement amplitude of the battery pack during placement or impact vibration is reduced, providing effective buffering and preventing damage to the battery pack.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution:

[0020] A forklift lithium battery pack includes a battery housing 1, a battery pack 2 placed inside the battery housing 1, and a sealing cover 3 set at the top of the battery housing 1. A support assembly is provided at the bottom of the battery housing 1, and the battery pack 2 is placed on top of the support assembly. Protective components that contact the battery pack 2 are respectively provided on the four side walls inside the battery housing 1. Multiple sets of limiting rods 4 are symmetrically arranged on both sides of the protective components. One end of the limiting rod 4 is fixedly connected to the inner wall of the battery housing 1, and a sleeve 6 is slidably sleeved on the outer side of the other end. A first spring 5 fixedly connected to the limiting rod 4 is installed inside the sleeve 6, and a buffer block 7 that contacts the battery pack 2 is installed on the outer side.

[0021] In use, the battery pack 2 is placed inside the battery housing 1, and then the sealing cover 3 is put on to seal the battery pack 2. By setting support components and protective components on the bottom and sides of the battery housing 1 respectively, the protective components can buffer and prevent collisions of the battery pack 2 inside the battery housing 1 during the operation of the forklift. At the same time, when the battery pack 2 shakes and hits the buffer block 7, it will drive the sleeve 6 to slide outside the limit rod 4 and squeeze the first spring 5 to further offset the collision force. By setting support components at the bottom, the movement amplitude of the battery pack 2 during placement or impact vibration is reduced, providing cushioning and preventing damage to the battery pack 2.

[0022] The support assembly includes a support base 8 located at the bottom of the battery box 1. The upper surface of the support base 8 is provided with a first foam board 9, a first sponge pad 10, a second foam board 11, a fixing plate 12 and a third foam board 13 in sequence. The battery pack 2 is placed on top of the third foam board 13.

[0023] Multiple sets of buffer mechanisms are symmetrically arranged between the fixed plate 12 and the support base 8. The buffer mechanism includes a damping rod 14 installed between the fixed plate 12 and the support base 8, and a second spring 19 is sleeved on the outside of the damping rod.

[0024] By setting the first foam board 9, the first sponge pad 10, the second foam board 11, and the third foam board 13, a multi-level buffering effect is achieved when the battery pack 2 is placed. At the same time, the damping rod 14, the second spring 19, and the first sponge pad 10 are compressed, which improves the buffering effect and avoids damage.

[0025] The protective components include a shock-absorbing pad 15 installed on the inner wall of the battery housing 1 and a shock-absorbing block 16 installed on the outer side of the shock-absorbing pad 15. A shock-absorbing airbag 17 is embedded inside the shock-absorbing block 16, and a wear-resistant layer 18 that contacts the battery pack 2 is provided on the outer surface of the shock-absorbing airbag 17.

[0026] The buffer block 7, the anti-collision pad 15, and the wear-resistant layer 18 are all made of rubber.

[0027] Made of rubber, it can achieve impact resistance. By using the anti-collision block 16 and the anti-collision airbag 17, the soft contact method can be used to deflect the impact force when it is hit.

[0028] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
