CN-117192878-B - Loading and unloading vehicle

Abstract

The invention provides a loading and unloading vehicle capable of easily confirming vehicle information when an operator gets off the vehicle. A forklift (1) for a loading/unloading vehicle comprises a vehicle body (1A) on which an operator (M) rides, and an image projection device (31) for projecting an image relating to vehicle information onto a road surface (G) in the direction in which the operator (M) gets off the vehicle (left). The forklift (1) further includes a get-off sensor that detects a get-off operation of the operator (M) when getting off, and the image projection device (31) projects an image when the get-off sensor detects the get-off operation.

Claims (5)

1. 1. A loading and unloading vehicle, comprising: A vehicle body for an operator to ride; an image projection device that projects an image related to vehicle information in a direction in which the operator gets off the vehicle so that the image is displayed on a road surface; a fork frame provided to the vehicle body, and A lifting device for lifting the fork frame, wherein the lifting device comprises a height sensor for detecting the lifting height of the fork frame, When the height sensor does not detect that the fork is connected with the road surface, the image projection device projects and displays the image on the road surface.
2. 2. The loading vehicle of claim 1, further comprising: a get-off sensor for detecting a get-off motion of the operator when getting off, The image projection device projects the image when the get-off sensor detects a get-off action.
3. 3. The loading vehicle of claim 2, wherein: The off-board sensor comprises an off-board sensor which detects the off-board of the operator on a seat arranged on the vehicle body.
4. 4. The loading vehicle of claim 2, wherein: The get-off sensor includes a human sensor that detects a portion of the operator.
5. 5. The loading vehicle of claim 1, further comprising: a push button switch configured to be switchable between a power on state and a power off state, and And a power supply circuit configured to supply power to the image projection apparatus until a specific time elapses when the key switch is switched from a power-on state to a power-off state.

Description

Loading and unloading vehicle Technical Field The present invention relates to a loading and unloading vehicle that displays vehicle information. Background In general, a forklift as a loading and unloading vehicle includes a display device that displays vehicle information. The display device includes a dashboard, a display, and the like, and is provided in front of the seat so that an operator sitting on the seat can easily confirm vehicle information (for example, see patent literature 1). However, even when the display device displays the vehicle information to be checked, the operator may get off the vehicle without watching the display device, that is, forget to check the vehicle information when getting off the vehicle. [ Prior Art literature ] [ Patent literature ] [ Patent document 1] Japanese patent laid-open publication 2016-132535 Disclosure of Invention [ Problem to be solved by the invention ] The present invention has been made in view of the above circumstances, and an object thereof is to provide a loading/unloading vehicle in which an operator can easily check vehicle information when getting off. [ Means of solving the problems ] In order to solve the above problems, a loading/unloading vehicle according to the present invention includes a vehicle body for an operator to ride on, and an image projection device for projecting an image related to vehicle information in a direction in which the operator gets off the vehicle so that the image is displayed on a road surface. In addition, the vehicle-off sensor is preferably further provided to detect a vehicle-off operation when the operator gets off, and the image projection device is preferably further provided to project the image when the vehicle-off sensor detects the vehicle-off operation. In addition, it is preferable that the get-off sensor includes an out-of-position sensor that detects an out-of-position of the operator on a seat provided in the vehicle body. In addition, it is preferable that the get-off sensor includes a human sensor that detects a part of the operator. The image projection apparatus preferably further includes a key switch configured to be switchable between a power-on state and a power-off state, and a power supply circuit configured to supply power to the image projection apparatus until a predetermined time elapses when the key switch is switched from the power-on state to the power-off state. [ Effect of the invention ] According to the present invention, it is possible to provide a loading/unloading vehicle in which an operator can easily confirm vehicle information when getting off. Drawings Fig. 1 (a) and 1 (B) are schematic configuration diagrams of a loading and unloading vehicle according to an embodiment of the present invention, where fig. 1 (a) is a side view and fig. 1 (B) is a plan view. Fig. 2 is a block diagram showing a schematic configuration of the loading and unloading vehicle according to the same embodiment. Fig. 3 (a) to 3 (C) are plan views showing a state in which an image is projected by the image projection apparatus. Fig. 4 (a) to 4 (C) are plan views showing a state in which an image is projected by the image projection apparatus.
