[0001] This utility model relates to the field of electric counterbalance forklift technology, specifically a replaceable battery compartment for an electric counterbalance forklift. Background Technology

[0002] Electric counterbalance forklifts are material handling equipment with lifting forks at the front of the vehicle body. They rely on the weight of the vehicle body to maintain stability. They have strong load-bearing capacity, good stability, durability and flexibility. Electric counterbalance forklifts are widely used in various scenarios such as railway freight yards, warehousing and logistics, ports and docks, retail distribution centers, and construction sites.

[0003] Batteries and electric motors are the main power units in electric counterbalance forklifts. The batteries are installed in the forklift via a battery compartment. Existing electric counterbalance forklift battery compartments are box-like structures, with the batteries stacked inside, making disassembly and replacement inconvenient. Therefore, we propose a replaceable battery compartment for electric counterbalance forklifts. Utility Model Content

[0008] A side plate is welded to one end of the base plate. A protective frame is fixed to the top of the base plate at equal intervals by bolts. A protective cover is provided on the outer side of the base plate. A sliding groove is opened on the inner side of the protective cover. A heat dissipation component is provided on the top of the protective cover. The heat dissipation component includes a ventilation box fixed to the top of the protective cover by bolts. An exhaust fan is installed at both ends of the ventilation box through mounting brackets. Reinforcing components are provided at equal intervals on both sides of the protective cover. The reinforcing components include sleeves welded to both sides of the protective cover at equal intervals. An n-shaped connecting rod is fitted on one end of the sleeve. Compression springs are fitted on both ends of the n-shaped connecting rod located inside the sleeve. A limiting ring is fixedly fitted on the outer side of the compression spring end of the n-shaped connecting rod.

[0009] Furthermore, a structural block is welded to one end of the side plate, an arc-shaped groove is formed at one end of the structural block, and a rectangular groove corresponding to the structural block is formed at one end of the protective cover.

[0010] Furthermore, the protective frame is welded with collars at equal intervals on both sides, corresponding to the n-shaped connecting rods.

[0011] Furthermore, a dustproof net is fixed inside the ventilation box located at the top of the exhaust fan by bolts, and a waterproof and breathable membrane is glued to the bottom of the dustproof net.

[0012] Furthermore, rollers are fixed at equal intervals to the bottom of the base plate by bolts.

[0013] Furthermore, bolt holes are equidistantly provided on one side of the side plate, and threaded grooves corresponding to the bolt holes are equidistantly provided at one end of the protective cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Place the battery box on the base plate and use bolts to fix the protective frame on the base plate. This will fix the battery box placed on the base plate. Use rollers to push the base plate into the protective cover. When the base plate enters the protective cover, its two sides are inserted into the sliding groove. Insert the bolts into the bolt holes and screw them into the threaded grooves. This will fix the side plate to one end of the protective cover, thus fixing the protective cover to the outside of the base plate.

[0016] When the base plate is inserted into the protective cover, the personnel pull the n-shaped connecting rod to move its end into the sleeve. After the base plate is fully inserted into the protective cover, the n-shaped connecting rod is released. The compression spring pushes the n-shaped connecting rod to move through the limit ring, so that one end of the n-shaped connecting rod is inserted into the collar. This can improve the connection stability between the protective cover and the base plate. When the personnel lift and move the protective cover, the base plate can be moved up and down. The exhaust fan works to extract the gas in the protective cover through the protective net, which is used to dissipate heat from the battery box on the base plate.

[0017] The replaceable battery compartment of this electric counterbalance forklift adopts a plug-in design. Pulling the base plate out from the protective cover can fully expose the battery box on the base plate, which is convenient for disassembly and replacement. The connection stability between the base plate and the protective cover can be improved by reinforcing components and collars, and the heat dissipation components can dissipate heat from the battery box inside the protective cover.
