Control handle assembly for electric forklift

Abstract

The invention discloses a control handle assembly for an electric forklift. The control handle assembly comprises a handle lower cover, accelerators, a membrane switch panel and a power module, wherein an elastic cylindrical pin is movably connected to one side of the top of the handle lower cover in a clamped mode, the accelerators are fixedly connected to the two ends of the elastic cylindricalpin in a clamped mode, and the membrane switch panel is fixedly connected to the center of the outer wall of one side of the handle lower cover in a clamped mode. A CAN communication mode is adopted,the working current of a handle is small, the anti-jamming capability is high, the appearance structure is stable due to the separated and combined structural design of the accelerators, and after-sales maintenance and accessory replacement are facilitated; a starting mode of unlocking by a key coded lock with ID swiping card is adopted, so that better operation experience is provided for customers, the selection diversity is increased, and after-sales maintenance and replacement are facilitated; and a gyroscope module is additionally arranged on the handle to replace the function of a proximity switch, so that the angle detection precision is more accurate, the anti-interference capability is high, the service life is prolonged, and the product is convenient to upgrade and maintain.

Description

technical field [0001] The invention relates to the technical field of forklift accessories, in particular to a control handle assembly for an electric forklift. Background technique [0002] An electric forklift is a forklift, which USES electricity to do its work, mostly for batteries. The electric forklift control handle is used for the driver to control various operations of the forklift. [0003] 1. In the prior art, the starting mode of the electric forklift handle is the key switch start and the button combination lock start. One: the friction of the key switch unlocking when the key is inserted, pulled out and rotated, resulting in a large mechanical loss, which leads to a short service life; Two: In the case that the customer loses or damages the key, it is impossible to quickly replace the accessories. At the same time, the matched lock cylinder must be disassembled and replaced together. It is difficult to maintain and causes additional losses (replacing a good l...

Problems solved by technology

[0003] 1. In the prior art, the starting mode of the electric forklift handle is the key switch start and the button combination lock start. One: the friction of the key switch unlocking when the key is inserted, pulled out and rotated, resulting in a large mechanical loss, which leads to a short service life; Two: In the case that the customer loses or damages the key, it is impossible to quickly replace the accessories. At the same time, the matched lock cylinder must be disassembled and replaced together. It is difficult to maintain and causes additional losses (replacing a good lock cylinder); the third: the key The password unlocking scheme is easy to cause the user to forget the unlocking password, or if the mask button fails or is damaged, the handle will not be able to unlock normally

[0004] 2. In the prior art, the electric forklift handle uses a proximity switch to control the handle rod for angle detection (safety performance), but the wiring harness and fixing method used by the proximity switch increase the cost of the product and the difficulty of installation (assembly). Compared with the detection of the angle, the Hall induction method is relatively rough, and the ability to resist external interference is relatively weak

[0005] 3. In the prior art, the electric forklift handle adopts analog communication mode, the handle has weak ability to resist external interference, and the working current is relatively large, which is prone to failure and difficult for after-sales maintenance.

[0006] 4. In the prior art, the structure of the handle accelerator of electric forklifts adopts an integrated single torsion spring design, which makes it difficult to replace accessories for after-sales maintenance. At the same time, the design of the single torsion spring limits the choice of product upgrades and changes
