As a core component of forklift technology, the door frame system integrates a series of precise components such as inner door frame, outer door frame, forks, lifting cylinder and chain. These components work together to complete the lifting and handling of goods. In particular, the lifting cylinder is stably installed at the bottom of the outer door frame, and the piston rod is connected to the top of the inner door frame. Through the precise cooperation of the two, the inner door frame is stably lifted in the outer door frame, thereby ensuring the accuracy and efficiency of goods handling.

[0003] However, this ingenious design also brings a problem that cannot be ignored - limited field of view. During forklift operation, the traditional door frame structure often blocks the forward view, making it difficult for the operator to perceive the obstacles or objects in front of the door frame in real time with the naked eye, which not only seriously affects the loading and unloading efficiency of goods, but also poses a great threat to operation safety. Especially in special conditions of forklift working conditions, such as high-speed transfer, the profile of the door frame structure will further hinder the field of view, increasing the risk of collision and accidents; while in low-speed stacking, the driver needs to clearly see the door frame profile to accurately judge the relative position state of the goods and the rack. This contradiction makes the problem of limited field of view more prominent. SUMMARY

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 In this embodiment of the present invention, a forklift mast vision aid device includes a vision aid 2 disposed on the mast 1, wherein the vision aid 2 is provided with at least one, as shown in the attached figure. Figure 2 As shown, in this embodiment, two vision assist units 2 are arranged. The two vision assist units 2 are respectively arranged on the channel steel on both sides of the forklift mast. The forklift mast is the main cause of the blind spot in front of the forklift. Therefore, the vision assist unit 2 is set at this location to eliminate the problem of the blind spot in front of the forklift caused by the mast.

[0025] The vision assistance unit 2 includes a display component 21 located on the gantry 1. A support structure 22 is provided on the gantry channel steel 11. The display component 21 is a display screen, and the display component 21 is fixedly connected to the gantry channel steel 11 through the support structure 22. In this embodiment, as shown... Figure 2 As shown, the support structure 22 includes a support leg fixedly connected to the side of the mast channel steel 11 and a support frame arranged perpendicularly to the support leg. The display component 21 is fixedly connected to the support frame. The display component 21 is a display screen. The display component 21 is set on the mast 1 and faces the forklift cab. An image acquisition component 23 is set on one side of the display component 21. In this embodiment, the image acquisition component 23 is a real-time high-definition camera used to acquire images in the blind spot in front of the mast. The image acquisition component 23 is used to acquire images and / or videos of the area in front of the mast 1 that is blocked by the mast 1 and display the image or video of the blocked area on the display component 21.

[0026] A fork carriage 3 is slidably connected to the mast 1. A forklift body is set on the side of the mast 1 away from the fork carriage 3. A control unit is set on the forklift body for receiving and processing signals from the image acquisition component 23 and sending data to the display component 21. The control unit has a built-in image processing module and control buttons are connected to the control unit.

[0027] A method of using a forklift mast visibility aid device includes the following steps:

[0028] Step 1: Start the forklift, select the intelligent control mode, and proceed to Step 2;

[0029] Step 2: Detect the forklift's driving status. In this embodiment, the forklift's driving status is detected by obtaining the current forklift speed V1 through the vehicle speed sensor and setting a judgment threshold V0. If the current vehicle speed V1 is less than the judgment threshold V0, the forklift is currently in a low-speed state; otherwise, the forklift is in a high-speed state. The specific judgment threshold can be set according to the vehicle and customer requirements. In this embodiment, the judgment threshold is one-third of the full-load speed.

[0030] If the forklift is at high speed, proceed to step 3; if the forklift is at low speed, proceed to step 4.

[0031] Step 3: Activate the image acquisition component to acquire images of the forklift's blind spots. Process the acquired images and display them in real time on the display component 21. In this embodiment, the image acquisition component captures images in front of the mast in real time. These images undergo image sampling and cropping processing, retaining only the portion of the driver's field of vision obstructed by the mast. In this embodiment, the driver drives in a normal sitting posture, looking straight ahead, and considering small head movements, the blind spot image under this posture is cropped out, and the remaining image portion is not used. This allows the driver to maintain a comfortable driving posture with their eyes looking straight ahead. Figure 4 As shown. Ultimately, these obstructed views will be displayed clearly and without delay on the screen, presenting the operator with a comprehensive and unobstructed visual environment, such as... Figure 4 As shown.

[0032] Step 4: The vision assistance device is not activated. That is, when the forklift travels at a speed lower than the speed threshold, the system determines that the forklift is in a low-speed stacking state. At this time, the camera and display screen will be automatically turned off, and the driver can clearly see the positional relationship between the goods and the mast so as to carry out precise stacking operations.

[0033] In addition, this application also includes a manual control mode, which includes a control switch to manually turn the vision assistance device on or off. If the driver selects to use the always-on display function, the camera and display will remain operational, providing the driver with continuous vision support. Figure 5 As shown.
