Detailed implementation manners

[0022] The following will, with reference to the accompanying drawings and through the description of embodiments, further elaborate on the specific implementation manners of the present utility model. The purpose is to help those skilled in the art have a more complete, accurate, and in-depth understanding of the concept and technical solution of the present utility model, and to facilitate its implementation.

[0023] As shown in Figures 1 to 5 the present utility model provides a forklift safety area monitoring device, which includes a device host 4, and an audible and visual alarm, a first camera 1, a second camera 2, and a third camera 3 that are electrically connected to the device host 4 through a connection line 5. The device host 4, the first camera 1, the second camera 2, and the third camera 3 are arranged on the overhead guard 10, and the device host 4 is located at the central position inside the overhead guard 10. The first camera 1, the second camera 2, and the third camera 3 are distributed at three different positions, and the connection line 5 is located inside the overhead guard 10.

[0024] Specifically, as shown in Figures 1 to 3 the first camera 1 is located at the rear side of the overhead guard 10, the forklift mast assembly is located at the front side of the overhead guard 10, the second camera 2 and the third camera 3 are located on the left and right sides of the overhead guard 10. The first camera 1, the second camera 2, and the third camera 3 are distributed in a triangular shape, and the second camera 2 and the third camera 3 are on the same straight line parallel to the width direction of the overhead guard 10. The second camera 2 and the third camera 3 are at the same height. The device host 4 is located at the middle position between the second camera 2 and the third camera 3, and the device host 4 is also located at the middle position between the first camera 1 and the mast assembly.

[0025] The overhead guard 10 is composed of multiple rectangular tubes. The device host 4 is arranged at the central position inside the top of the overhead guard 10, and the connection line 5 is arranged inside the rectangular tubes that make up the overhead guard 10. An opening position is left on the front cover of the device host 4 for convenient debugging and maintenance. The cameras and the audible and visual alarm do not require extension cables, which not only reduces the assembly time and cost but also avoids the difficulty that too many patch cords cannot be threaded through the rectangular tubes at the same time. It solves the problems of the traditional exposed wire arrangement being not beautiful, having too many patch cords, and having blind spots in the monitoring area, thereby improving the aesthetics.

[0026] Preferably, the first camera 1, the second camera 2, and the third camera 3 are all AI infrared cameras. The first camera 1, the second camera 2, and the third camera 3 are used to take pictures of the surrounding environment of the forklift. With a large number of cameras, the monitored area is large, which helps to improve the safety during the forklift operation.

[0027] As shown in Figure 1 and Figure 4As shown in the figure, a first monitoring bracket 11 is provided on the overhead guard 10, and the first camera 1 is installed on the first monitoring bracket 11. The first monitoring bracket 11 includes a first upper mounting plate 1101 and a first lower mounting plate 1102. The first upper mounting plate 1101 is connected to the overhead guard 10, and the first camera 1 is fixedly installed on the first lower mounting plate 1102 by bolts. The included angle between the first upper mounting plate 1101 and the first lower mounting plate 1102 is an obtuse angle. The first upper mounting plate 1101 is vertically arranged, and the first lower mounting plate 1102 extends obliquely downward towards the lower part of the first upper mounting plate 1101. Since the first camera 1 has a field of view of only 70° in the vertical direction and the angle adjustment in the up and down directions is small, bending the first monitoring bracket 11 into an obtuse angle can avoid the blind area close to the vehicle body, improve the imaging effect, and ensure the monitoring range.

[0028] As Figure 1 and Figure 4 shown in the figure, the first upper mounting plate 1101 is installed on the overhead guard 10 by a fastener formed by a plurality of first bolts and nuts. The first upper mounting plate 1101 is provided with a first upper mounting hole 1104 for the first bolt to pass through. The first upper mounting hole 1104 is an oblong hole and is vertically arranged. The overhead guard 10 is provided with a threaded hole for the first bolt to be inserted. Each first bolt passes through a first upper mounting hole 1104 respectively. The length of the first upper mounting hole 1104 provided on the first upper mounting plate 1101 is greater than the diameter of the first bolt. The first upper mounting hole 1104 is set as an oblong hole, which is convenient for the installation of the bracket and facilitates the adjustment of the installation position of the camera.

[0029] As Figure 1 and Figure 4 shown in the figure, two first upper mounting holes 1104 and a first avoidance hole 1103 are provided on the first upper mounting plate 1101. The first avoidance hole 1103 is used for the connection line 5 connecting the first camera 1 to pass through. The first avoidance hole 1103 is located between the two first upper mounting holes 1104.

[0030] As Figure 1 and Figure 5As shown in the figure, two second monitoring brackets 12 are provided on the overhead guard 10, and the second camera 2 and the third camera 3 are respectively installed on the two second monitoring brackets 12. The second monitoring bracket 12 includes a second upper mounting plate 1201 and a second lower mounting plate 1202. The second upper mounting plate 1201 is connected to the overhead guard 10. The second camera 2 is fixedly installed on the second lower mounting plate 1202 of one second monitoring bracket 12 by bolts, and the third camera 3 is fixedly installed on the second lower mounting plate 1202 of the other second monitoring bracket 12 by bolts. The included angle between the second upper mounting plate 1201 and the second lower mounting plate 1202 is an obtuse angle. The second upper mounting plate 1201 is vertically arranged, and the second lower mounting plate 1202 extends obliquely downward toward the lower part of the second upper mounting plate 1201. The second lower mounting plates 1202 of the two second monitoring brackets 12 are distributed in a V shape. Since the vertical field of view of the second camera 2 and the third camera 3 is only 70°, and the angle adjustment up and down is small, bending the second monitoring bracket 12 into an obtuse angle can avoid the blind area close to the vehicle body, improve the camera effect, and ensure the monitoring range.

The second upper mounting plate 1201 is provided with a second upper mounting hole 1204 for the second bolt to pass through. The second upper mounting hole 1204 is an oblong hole and is vertically arranged. The overhead guard 10 is provided with a threaded hole for the second bolt to be inserted. Each second bolt passes through a second upper mounting hole 1204 respectively. The length of the second upper mounting hole 1204 provided on the second upper mounting plate 1201 is greater than the diameter of the second bolt. The second upper mounting hole 1204 is set as an oblong hole, which is convenient for the installation of the bracket and facilitates the adjustment of the installation position of the camera.

[0032] As Figure 1 and Figure 5 shown, two second upper mounting holes 1204 and a second avoidance hole 1203 are provided on the second upper mounting plate 1201. The second avoidance hole 1203 is used for the connecting wire 5 connecting the second camera 2 and the third camera 3 to pass through. The second avoidance hole 1203 is located between the two second upper mounting holes 1204.

[0033] As Figure 1 and Figure 2 shown, the overhead guard 10 is adapted with an opening. All cables are routed inside the rectangular pipe. A sealing plate 9 is provided on the overhead guard 10. The sealing plate 9 covers the equipment host 4 and all the rear-end connectors, which is simple and beautiful. Moreover, the sealing plate 9 is densely provided with through holes arranged throughout to ensure that the signal is not shielded.
