Description

Technical Field

[0001] This utility model belongs to the technical field of forklift power battery housing, specifically a split-type housing structure for forklift power battery counterweight. Background Technology

[0002] Lithium batteries have a wide range of applications, including automobiles, electric vehicles, UPS power supplies, energy storage, data center communications, and forklifts. Under the backdrop of new national environmental policies and the "oil-to-electric" conversion, the trend of lithium battery adoption in forklifts is accelerating. Lithium batteries have become the mainstream power source for electric forklifts due to their advantages such as fast charging speed, long lifespan, environmental friendliness, energy efficiency, and light weight. As a key component of electric forklifts, the power battery casing carries and protects the battery, ensuring battery safety and stable forklift operation.

[0003] The forklift battery housing is a component in electric forklifts used to mount and secure the power battery. It provides protection for the battery and ensures its stability and safety during forklift operation. The counterweights in the forklift battery housing increase the forklift's center of gravity, effectively improving stability, reducing safety accidents caused by forklift swaying, and ensuring smooth operation during forklift work.

[0004] Traditional forklift battery boxes typically employ a one-piece design, requiring more materials and processes in their manufacture, and demanding higher skill levels, making them relatively complex to produce. Furthermore, the installation process for traditional forklift battery boxes is usually quite cumbersome, requiring more time and labor costs, and demanding higher skill levels from installers, resulting in a lack of ease of manufacturing and installation.

[0005] Therefore, a split-type box structure for counterweight of forklift power battery is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a split-type box structure for the counterweight of a forklift power battery so that the battery box mechanism, counterweight mechanism and top cover mechanism are prefabricated in batches and then directly welded together.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A split-type box structure for counterweight of forklift power battery includes a battery box mechanism, a counterweight block mechanism and a top cover mechanism. The battery box mechanism includes a battery box body. The upper surface of the battery box body is fixedly connected to two ends of ear plates. The outer surface of the ear plates is provided with lifting holes. The lower outer surface of the battery box body is provided with threaded holes.

[0009] The top cover mechanism includes a connecting groove, a counterweight body is fixedly connected to the lower surface of the connecting groove, lower lifting holes are opened on both outer surfaces of the connecting groove, threaded through holes are opened on the front and rear sides of the connecting groove, the inner sidewall of the connecting groove is slidably connected to the lower outer surface of the battery box body, and a welding joint is opened on the inner bottom surface of the connecting groove.

[0010] Furthermore, a charging port cover is provided at the charging port on the left side of the battery box body, and a charging plug-in mounting component is fixedly connected to the inner side wall of the battery box body near the charging port cover. A beetle bouncer is installed inside the charging plug-in mounting component, and the beetle bouncer is connected to the charging port cover via a self-locking hinge.

[0011] Furthermore, the counterweight mechanism includes a cover plate, which is fixedly connected to the upper surface of the battery box body, and a cable connector mounting component is installed on the upper surface of the cover plate.

[0012] Furthermore, there are several threaded holes and several threaded through holes, and each of the several threaded holes corresponds to one of the several lower lifting holes.

[0013] Furthermore, a wire tie bracket is fixedly connected to the upper end of the inner side wall of the battery box body.

[0014] Furthermore, the number of the wire tying brackets is several, and the several wire tying brackets are symmetrically arranged on the upper inner side wall of the battery box body.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] In this invention, when assembling the counterweight housing of a forklift power battery, the connecting groove and the counterweight body can be welded together from the bottom welding joint. Then, the battery housing mechanism can be lifted by the lifting equipment through the upper lifting hole, and the top cover mechanism can be lifted by the lifting equipment through the lower lifting hole. The lower end of the battery housing body is then inserted into the connecting groove. After aligning several threaded holes and several threaded through holes, bolts are used to lock them in place, completing the assembly of the battery housing mechanism and the top cover mechanism. Then, the charging plug-in mounting parts and other battery components can be installed inside the battery housing body, and the cover plate can be welded to the upper surface of the battery housing body. Through the combination of the above structures, the forklift power battery housing can be prefabricated in a modular manner. The prefabricated battery housing mechanism, counterweight mechanism, and top cover mechanism can be directly welded and assembled, which has the advantages of simple and convenient manufacturing and easy installation.
