A battery locking device and an electric forklift

Abstract

The invention discloses an accumulator locking device and an electric forklift truck. The accumulator locking device comprises a fixing base connected with a frame, wherein one end of the fixing base is movably connected with a thrust mechanism, the other end of the fixing base is movably connected with a swing frame with one end movably connected with the thrust mechanism, and a pressing plate or a pressing rod for pressing a press opening formed in an accumulator box is arranged at the other end of the swing frame. The fixing base of the accumulator locking device is directly installed on the frame, the pressing plate or the pressing rod directly presses or releases the inner side of the accumulator through opening or pressing operation, accumulator locking can be achieved without basic hand tools, and the accumulator locking device is firm in locking and convenient to use.

Description

technical field [0001] The invention relates to the fields of working devices or vehicles powered by batteries, and in particular to a battery locking device and an electric forklift. Background technique [0002] For working devices and vehicles powered by batteries, take the side-access electric storage vehicle in industrial vehicles as an example. Most of the current storage truck forklifts are powered by battery batteries. In order to improve the working time of the equipment, the method of increasing the battery capacity is usually used; because the weight of the battery is proportional to the capacity, the weight of the battery box group with a 24V voltage of 300A·h is more than 200kg , The batteries of storage and handling equipment need to be maintained and charged frequently, or even replaced, and it is difficult to achieve uninterrupted operation with a single set of batteries. Easy to replace and lock the battery has become the content that must be considered in ...

AI Technical Summary

Problems solved by technology

The locking mechanism adopts a hard limit position, which is easy to produce gaps due to manufacturing errors or long-term use, causing shaking; some parts are not fixed on the frame and are easy to lose

[0010] The above-mentioned fixing device is used on the battery of the side-loading storage vehicle. Since the battery box uses rollers and bearings as the battery track and adopts an integral locking and clamping mechanism, the structure is complex and the cost is high; the integrated battery locking structure is adopted. Due to the space Limitations, the design structure usually has a small force-bearing area and thin structure, and it is easy to damage the paint on the surface of the battery during operation; or use hard limits to limit the position of the battery, and use baffles and bolts to lock the battery. This technology locks firmly, but usually accompanied by There are disadvantages such as relatively simple structure, easy damage and loss of functional components, need for on-board tools to assist in operation, and relatively long operating time to realize functions, etc.
