[0041] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0042] Combination Figure 1 and Figure 2 As shown, the utility model provides an all-round forklift monitoring device including a left camera 1 arranged on the left side of the top of the forklift, a right camera 2 arranged on the right side of the top of the forklift, a driver camera 3 and a front camera 4 arranged in the cab, a rear camera 5 arranged at the rear of the forklift, a monitoring display screen and a reversing image display screen arranged in the cab, and a monitoring host 6, a control box 7, a reversing radar, and a DC converter 8 arranged on the counterweight of the forklift; the left camera 1, the right camera 2, the driver camera 3 and the front camera 4 are respectively connected to the monitoring host 6 through an electrical wiring harness, and the monitoring host 6 is connected to the monitoring display screen through an electrical wiring harness; the reversing radar and the rear camera 5 are respectively connected to the control box 7 through an electrical wiring harness, and the control box 7 is connected to the reversing image display screen through an electrical wiring harness.

[0043] The omnidirectional forklift monitoring device of the utility model is provided with a plurality of cameras in different directions. The cameras in the front left, right and cab directions are connected to the monitoring host 6 through signal lines. The monitoring host 6 outputs video signals to the monitoring display screen, covering all important viewing angles around the forklift and the driver's position. This allows the driver to monitor the environment around the forklift in real time, prevent accidents caused by blind spots, and improve the safety and accuracy of driving operations.

[0044] The rear camera 5 and the reversing radar probe arranged at the rear of the forklift are connected to the control box 7 through the electrical harness, and the signal is transmitted to the reversing image display screen. The combined use of the reversing radar and the rear camera 5 can effectively warn of rear obstacles and reduce collision accidents caused by reversing operations. This multiple detection and warning system can provide additional safety protection when the driver's field of vision is limited or the operation is complicated.

[0045] The monitoring host, control box and display screen are powered by a DC converter. Since the body voltage of the forklift may be different from the input voltage of the electrical equipment on it, the DC converter can convert the body voltage into a power output suitable for each device. This design simplifies the management and maintenance of the electrical system and ensures that each device can operate stably and reliably.

[0046] In summary, this all-round forklift monitoring device greatly enhances the safety, accuracy and efficiency of forklift operations through optimized monitoring layout, safety warning system and power supply method.

[0047] In the present invention, the left camera 1, the right camera 2, the driver camera 3 and the rear camera 5 are all adjustable cameras. The adjustable camera allows the driver to adjust the viewing angle and position of the camera according to the needs of the specific working environment. This flexibility can effectively reduce blind spots and improve the overall field of view during operation. Moreover, different drivers may have different heights, vision and operating habits. The adjustable camera can meet the personalized needs of different drivers.

[0048] Combination Figure 1 and Figure 7 As shown, in the utility model, the all-round forklift monitoring device also includes a monitoring installation assembly 9, which is installed on the left and right sides of the upper surface of the forklift top assembly. The monitoring installation assembly 9 includes a first connecting member 91 fixedly connected to the forklift top assembly, and a second connecting member 92 and a third connecting member 93 vertically connected to the first connecting member 91 and arranged at intervals. This design ensures the stability and reliability of the camera and the strip light when installed on the top of the forklift, and is not easily affected by vibration or movement, thereby ensuring the stable operation of the equipment.

[0049] The second connecting member 92 is provided with a first fixing hole 94 for installing the forklift light strip, and the third connecting member 93 is provided with a second fixing hole 95 for installing the camera. This partition arrangement makes full use of the space on the top of the forklift, so that the light strip and the camera can be installed independently without interfering with each other, ensuring the effective performance of their respective functions.

[0050] Two welding studs 96 are provided on the first connecting member 91, which are parallel to the second connecting member 92 and the third connecting member 93. Since there are wire harnesses behind the camera and the strip light, the welding studs 96 are used to fix the wire harnesses with the wire harness clips and guide the wire harnesses through the wire holes on the side of the overhead guard, which effectively manages the wire harnesses, avoids clutter, prevents the wire harnesses from shaking when the forklift is driving, and reduces the risk of the wire harnesses being damaged by the external environment.

[0051] In the present invention, the all-round forklift monitoring device also includes a signal light installation assembly 10 arranged around the outside of the rear air conditioner of the forklift, and the rear of the signal light installation assembly 10 is fixedly connected to the rear camera 5. The rear air conditioner of the forklift is installed on the top of the cab and protrudes backwards. The signal light installation assembly 10 surrounds the outer periphery of the rear air conditioner and is used to install warning lights, strip lights and the rear camera 5.

[0052] In the present invention, the all-round forklift monitoring device also includes a driver monitoring mounting plate 11, a monitoring display bracket 12, a reversing image display bracket 13 and a front camera mounting plate 14 arranged in the cab; the driver monitoring mounting plate 11 is fixed to the left front leg of the forklift overhead guard frame, and is used to install the driver camera 3; the monitoring display bracket 12 and the reversing image display bracket 13 are fixed to the right front leg of the forklift overhead guard frame in sequence, and are used to install the monitoring display and the reversing image display respectively; the front camera mounting plate 14 is fixed to the front grille of the forklift overhead guard frame, and is used to install the front camera 4. Specifically, Figure 8 As shown, the driver monitoring mounting plate 11 is provided with a mounting hole 111 fixedly connected to the left front leg of the forklift overhead guard and an adjustable mounting hole 112 for mounting the driver camera 3 .

[0053] The adjustable mounting hole 112 is provided so that the driver's camera 3 can be rotated up and down, which is convenient for finding the driver's position. The monitoring display screen bracket 12 on the right front leg of the forklift overhead guard is also the same, and the display screen can be rotated up and down, and can also be installed left and right.

[0054] Preferably, combined Figure 4 and Figure 6 As shown, the front camera mounting plate 14 includes an upper fixing plate 141 fixedly connected to the front grille of the forklift overhead guard and a lower fixing plate 142 connected to the upper fixing plate 141 and forming an angle of 125°; the upper fixing plate 141 is provided with an upper fixing hole 143 for mounting the forklift wide-angle rearview mirror in a stacked manner; the lower fixing plate 142 is provided with a lower mounting hole 144 for fixing the front camera 4, and the lower fixing plate 142 is also provided with a semicircular threading hole 145 for the wiring harness of the front camera 4 to pass through.

[0055] Specifically, a fan mounting plate is provided on the forklift overhead guard, and the right end of the front grid plate is used to install the fan. If there is not enough space, the wide-angle rearview mirror is installed on the two upper fixing holes 143 in the middle of the front grid plate. The fixing hole 143 first fixes the front camera mounting plate 14, and then fixes the wide-angle rearview mirror. The front camera 4 is installed on the lower mounting hole 144 and the semicircular threading hole 145 of the front camera mounting plate 14 facing forward. Although the front camera 4 cannot be adjusted, it is small in size and can be hidden on the edge of the wide-angle rearview mirror to prevent the driver from hitting his head. The angle between the front grid plate and the horizontal plane is 45°, and the angle between the upper fixing plate 141 and the lower fixing plate 142 of the front camera mounting plate 14 is 125°. This design ensures that the front camera 4 can have a good front observation range and can cover important operating areas.

[0056] like Figure 2 As shown, a plurality of reversing radar holes 15 are provided on the counterweight, and the plurality of reversing radar holes 15 are spaced apart along the width direction of the forklift body and can respectively install the reversing radars. The plurality of reversing radar holes 15 are spaced apart along the width direction of the body and can effectively cover various areas behind the forklift. Such a layout ensures that the forklift can fully sense the obstacles behind when reversing, and avoids collision accidents that may be caused by blind spots in the field of vision.

[0057] In some embodiments, four reversing radar holes 15 are arranged at intervals along the width direction of the vehicle body for installing reversing radar probes. The four reversing radar probes are connected to the control box 7 also arranged on the counterweight through a signal line. Each reversing radar probe can measure the distance to the obstacle at its location. Through the signal transmitted by the control box 7, the driver can see the distance and position information of the rear obstacle in real time on the reversing image display screen. This precise distance measurement helps the driver to perform accurate reversing operations and avoid contact with obstacles. In addition, the design of installing the reversing radar probe on the counterweight ensures that the probe is not easily disturbed or damaged by the outside world when reversing, thereby improving the reliability and stability of the entire reversing assistance system.

[0058] A second aspect of the utility model provides a forklift, which has the above-mentioned omnidirectional forklift monitoring device. By introducing the above-mentioned omnidirectional forklift monitoring device into the forklift, omnidirectional monitoring of the front, back, left, right and inside of the cab of the forklift can be achieved.

[0059] It is understandable that the forklift of the utility model is equipped with a rear air conditioner, the cab of the forklift is mounted on the overhead guard, the overhead guard is mounted on the frame, a counterweight is mounted at the rear of the frame, the cab includes a front window assembly, left and right side doors, a rear window assembly and a top assembly, in order to improve the driver's comfort, the rear air conditioner can be set as a cold and warm air conditioner, and the size of the air inlet and outlet of the cold and warm air conditioner docking with the cab space is increased. Since the rear air conditioner itself protrudes backward, in order not to increase the external dimensions of the forklift, the increased size will extend 100mm into the cab space. Therefore, the rear fixing screws of the forklift top assembly and the rear crossbeam of the overhead guard are 175mm away from the tail edge. In addition, the rear air conditioner is installed on the overhead guard, and there are many wire harnesses and water pipes in the special-shaped tubes on the left and right sides of the top of the overhead guard. There must be no screws to fix the top assembly, which are too sharp and easy to scratch the wire harnesses and water pipes. In addition, the rear crossbeam of the overhead guard is hollow, so the two rear fixing screws and two fixing screws that fix the top assembly are connected to the rear crossbeam. The two side fixing screws are used to fix the top assembly on the left and right side special-shaped pipes in the middle of the top of the top guard. Therefore, the side fixing screws and the fixing screws are not in a straight line, and the distance deviation is 35mm. Fig. 9 shown.

[0060] Preferably, combined Figure 3 and Figure 5 As shown, the left and right sides of the forklift are provided with outlet holes 16, and the left and right sides of the forklift are provided with semicircular holes 17. The outlet holes 16 and the semicircular holes 17 on the left and right sides of the forklift are respectively arranged concentrically. The outlet holes 16 are used for the wire harnesses of the strip lights and cameras on the left and right sides of the forklift to pass through, and the semicircular holes 17 are used to guide the wire harnesses to the outlet holes 16 on the side of the forklift. This routing method prevents the wire harnesses from being cut or damaged by the edge of the forklift top assembly during movement.

[0061] The preferred implementation modes of the present invention are described in detail above in combination with the accompanying drawings and embodiments, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
