Embodiment 1

[0039] Such as Figure 4 As shown, the operating handle 1 includes a handle rod 11 and a handle base 12 . The handle base 12 is vertically provided with mounting plates 121 parallel to each other, and a rotating shaft 122 is fixedly installed between the mounting plates 121 through elastic pins 1211 . One end of the handle rod 11 is provided with a connecting plate 111 parallel to the mounting plate 121 and docked with the mounting plate 121 . A through hole 112 is provided on the connecting plate 111 corresponding to the position of the rotating shaft 122 , so that the rotating shaft 122 is rotatably connected to the handle bar 11 through the through hole 112 . The other end of the handle bar is fixedly connected to the handle head 13. The handle bar 11 swings in a vertical plane with the rotating shaft 122 as the axis. A magnetic sensitive component 1221 is disposed at one end of the rotating shaft 122 , and a Hall element 1121 is disposed outside the through hole 112 of ...

Embodiment 2

[0042] The industrial vehicle travel control device described in the second embodiment has many similarities with the first embodiment. For the sake of brevity, this embodiment focuses on the differences. For the similarities, please refer to the description of the first embodiment.

[0043] When the minimum speed at which the vehicle is driven by the fast state area 31 is far greater than the fastest speed at which the vehicle is driven by the slow state area 33 . In order to prevent the speed difference between the fast speed and the slow speed of the vehicle from being too large, resulting in a sudden change in the speed of the vehicle when switching between the fast state area and the slow state area, causing discomfort to the operator; at the same time, reducing safety accidents caused by misoperation risks of. Embodiment 2 A transition state area 34 is set between the fast state area 32 and the slow state area 33 . The speed at which the vehicle is driven by the transit...

Embodiment 3

[0046] The industrial vehicle driving control device described in the third embodiment has many similarities with the first embodiment. For the sake of brevity, this embodiment focuses on the differences. For the similarities, please refer to the description of the second embodiment.

[0047] The positions of the Hall element and the magnetic-sensing component in Embodiment 1 are reversed, the Hall element is arranged at one end of the rotating shaft, and the magnetic-sensing component is arranged outside the through hole of the connecting plate, so that the Hall element is located inside the magnetic-sensing component and faces it.

Abstract

The invention belongs to the field of mechanical equipment, and in particular relates to an industrial vehicle driving control device and method. It is mainly used in handling industrial vehicles. The angle area of ​​the handle rod can be set through personalized parameters to solve the technical problem that the operation handle is limited in a small space. It is characterized in that it includes: a detection device, which is used to detect the swing angle of the operating handle and convert it into a unique corresponding analog electric signal. And a vehicle controller, which is electrically connected to the motor brake and the traction motor of the vehicle, the vehicle controller is electrically connected to the detection device, and controls the working states of the motor brake and the traction motor according to the analog electrical signal output by the detection device.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to an industrial vehicle driving control device and method. Background technique [0002] During the process of transporting and driving, industrial vehicles for handling can automatically adjust the driving or braking of the vehicle according to the different angle positions of the operating handle. Such as figure 1 As shown, it is triggered by setting a micro switch or a proximity switch at the connection between the handle rod of the operating handle and the handle seat. The swing range of the operating handle is divided into different angle areas by using the switch and the mechanical concave-convex structure, corresponding to each state area of ​​the operating handle. When the operating handle is rotated to a specified angle position, the mechanical concave-convex structure triggers the switch to control the vehicle to enter the vehicle driving state or the veh...
