[0025] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] For construction machinery like excavators and loaders, the field of view (FOV) and angles of view (LAV) cannot be fully simulated using 3D models alone, resulting in field of view deviations. Therefore, field simulation of the field of view of construction machinery is crucial.

[0029] See Figure 1 and Figure 2 The present invention provides a visual field simulation test device, comprising a base 1, a support rod 2, a sliding member 3, a fixture 4, and a laser pointer 5. The support rod 2 is mounted on the base 1 and extends in the Z direction. The sliding member 3 is mounted on the support rod 2 so as to be slidable in the Z direction. The fixture 4 is rotatably mounted on the sliding member 3. The laser pointer 5 is mounted on the fixture 4, and the fixture 4 clamps the laser pointer 5.

[0030] The base 1 can adopt a SIP calibration device, which serves as a support base to facilitate the stable placement of the visual field simulation test device. The support rod 2 is fixedly mounted on the base 1 and can be connected by screws, clamping, plugging, etc. to provide support for the height adjustment in the Z direction. The slide 3 slides in the Z direction on the support rod 2 to achieve the height adjustment of the laser pen 5, and the rotation installation of the clamp 4 makes the angle of the laser pen 5 adjustable. In this way, the visual field simulation test device can be actually applied to engineering machinery vehicles, so that the field of view pitch angle and left and right angle line of sight can be simulated and tested quickly and directly. The operation is light and fast, and the height position and angle can be flexibly adjusted according to the actual working conditions to more accurately simulate the eye point position.

[0031] Generally, the Z-direction length of the support rod 2 is sufficient to allow the sliding member 3 to slide within the required range for the visual field test of the construction machinery, indicating that the support rod 2 is sufficiently long. However, when performing a visual field test on construction machinery, there may be limited space available, and a longer support rod 2 may not be sufficient. Alternatively, some construction machinery may require an extremely large space for the visual field test, and the support rod 2 may not be long enough to meet the test requirements.

[0032] To this end, the support rod 2 is a telescopic rod, which includes a base rod and an extension rod. The base rod is fixed on the base 1 in the Z direction, the extension rod is sleeved and connected to the base rod, and the extension rod can slide relative to the base rod in the Z direction to make the support rod 2 telescopic. The base rod and the extension rod are connected by a positioning piece, and the sliding piece 3 can be slidably installed on the extension rod in the Z direction.

[0033] The base rod is fixedly mounted on the base 1 by screws, clamping, plugging, etc., making installation and replacement convenient. The extension rod can be inserted into the base rod, or the extension rod can be sleeved outside the base rod. Regardless of the structure, the extension rod can be extended upward or retracted downward to achieve the extension or shortening of the support rod 2. After being extended and retracted into place, it is fixed by screws, pins, etc. positioning parts. In this way, the visual field simulation test device can be used in smaller spaces, and can also provide a sufficiently large sliding range for the slider 3 to meet the visual field simulation requirements of large spaces.

[0034] The slider 3 is mounted on the support rod 2 so as to slide in the Z direction, and the slider 3 and the support rod 2 are positioned by a connector. The slider 3 is mounted on the support rod 2 to slide along the support rod 2. After sliding into place, the slider 3 is fixed by a connector such as a screw or a pin, thereby fixing the height position of the laser pointer 5.

[0035] The clamp 4 clamps the laser pointer 5 with an elastic clamp and locks it with a locking member. The clamp 4 can rotate in both pitch and left and right directions, allowing the laser pointer 5 to simulate and test its pitch angle and left and right angles of view. The elastic clamp, which can be made of nylon, holds the laser pointer 5 in place and is secured with screws or other means to ensure that the clamp 4 can stably hold the laser pointer 5.

[0036] The X direction is used as the reference direction of the laser pen 5, that is, the laser pen 5 is set horizontally and perpendicular to the sliding member 3. An inclinometer is provided in the Y and Z directions to record the pitch rotation and left and right rotation angles of the laser pen 5, so that the visual field simulation test can be accurately performed.

[0037] It should be noted that the visual field simulation test device is primarily used to simulate the visual field of a worker's eyes. Unless otherwise specified, workers see through both eyes. Accordingly, the visual field simulation test device needs to be able to simulate the visual field of both eyes. Therefore, the slider 3 is fixedly connected to a horizontally arranged eye distance scale 6. Two rotatable clamps 4 are mounted on the eye distance scale 6, spaced apart and spaced apart. The distance between the two clamps 4 is the distance between the two eyes, and each clamp 4 holds a laser pointer 5.

[0038] The eye distance scale 6 is engraved with scales along its horizontal extension direction to facilitate the simulation of the interocular distance. When the two clamps 4 are installed on the eye distance scale 6 at intervals, it is necessary to ensure that the distance between the two laser pointers 5 is equal to the interocular distance, thereby ensuring the accuracy of the visual field simulation test.

[0039] On this basis, the slider 3 is rotatably mounted on the support rod 2, and the slider 3 can drive the eye distance scale 6 to rotate 360° around the Z axis. The slider 3 and the support rod 2 are positioned by a connector. The slider 3 is mounted on the support rod 2 and can not only slide in the Z direction but also rotate 360° around the support rod 2, thereby simulating the visual field of an operator turning around, allowing for more accurate visual field simulation testing.

[0040] Furthermore, with the fixture 4 positioned horizontally and perpendicular to the eye-distance scale 6 as a reference of 0°, the fixture 4 can pitch and rotate by -45° to 90° relative to the eye-distance scale 6, and can rotate left and right by -90° to 90° relative to the eye-distance scale 6. This angle range, combined with the rotation of the slider 3, accurately simulates the operator's field of view, which can be turned, pitched, and twisted left and right, allowing the visual field simulation test device to perfectly match the operator's field of view.

[0041] Furthermore, the clamp 4 is detachably connected to the eye-distance scale 6, and / or the clamp 4 can slide horizontally relative to the eye-distance scale 6, allowing for adjustable spacing between the two clamps 4. Different workers not only have different heights but also different eye distances. By making the clamp 4 detachably connected to the eye-distance scale 6 and / or allowing the clamp 4 to slide horizontally relative to the eye-distance scale 6, the spacing between the two laser pointers 5 can be flexibly adjusted, thereby precisely matching the eye distance.

[0042] The fixture 4 slides horizontally relative to the eye distance scale 6. The eye distance scale 6 has a horizontally extending slot within which are mounted two sliding blocks 7 that can slide along the slot. The two fixtures 4 are rotatably mounted on the two sliders 7. The two sliders 7 can be pushed and slid to adjust the distance between the two laser pointers 5.

[0043] It is worth noting that when there is no external force, the two sliders 7 will not slide relative to the eye distance scale 6, so as to ensure that after the adjustment is in place, the visual field simulation test can be performed stably and accurately.

[0044] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
