Description

Technical Field

[0001] This invention relates to the field of wheel steering detection technology, specifically a wheel steering detection device. Background Technology

[0002] A wheel is a rigid wheel that fixes the inner part of the tire, supports the tire, and shares the load with the tire. In other words, a wheel is a rotating component that bears the load between the tire and the axle. It usually consists of two main parts: the spokes and the rim. When using a wheel, it is necessary to determine the wheel's direction of travel so that the user can clearly understand the wheel's direction of travel.

[0003] Chinese patent discloses a graded control method for wheel steering (authorization announcement number CN 111674463 B). This patented technology uses graded control of wheel rotation. When the steering angle is large, it uses a control method where all four wheels rotate together, reducing the turning radius and making it easier for the vehicle to pass through narrow areas, thus increasing its flexibility. The wheel steering system of this invention can achieve the same technical effect. However, although this patent uses graded control of wheel rotation, its discrimination effect is poor. Using only one method for discrimination will affect the discrimination effect, and the discrimination device is also inconvenient to install and disassemble. Therefore, those skilled in the art have provided a wheel steering discrimination device to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to provide a wheel steering detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A wheel steering detection device includes a steering rod and a detection wheel disposed on one side of the steering rod. A base frame is disposed below the steering rod, and a mounting plate is mounted on the upper surface of the base frame. A pull plate is disposed on the upper surface of the mounting plate, and a limit rod is mounted on the lower surface of the pull plate. A control box and a signal receiving box are disposed on the upper surface of the mounting plate from left to right on one side of the pull plate. A monitoring box is disposed on the upper surface of the signal receiving box. A laser emitting box is disposed on one side of the detection wheel, and a laser emitter is disposed inside the laser emitting box. A first photoelectric receiver, a second photoelectric receiver, a third photoelectric receiver, and a fourth photoelectric receiver are disposed on one side of the signal receiving box from front to back. A distance sensor is disposed below the first photoelectric receiver on one side of the signal receiving box. A controller and a signal receiving module are disposed inside the signal receiving box from front to back, and a wireless transmission module is disposed inside the control box.

[0007] The outputs of the first, second, third, and fourth photoelectric receivers are all connected to the input of the controller. The output of the controller is connected to the input of the wireless transmission module. The output of the wireless transmission module is connected to a wireless audible and visual alarm module and an external monitoring and display device. The external monitoring and display device includes a display screen, a first indicator light, a second indicator light, a third indicator light, and a fourth indicator light. The first indicator light corresponds to the first photoelectric receiver, the second indicator light corresponds to the second photoelectric receiver, the third indicator light corresponds to the third photoelectric receiver, and the fourth indicator light corresponds to the fourth photoelectric receiver. The first indicator light is red, the second indicator light is yellow, the third indicator light is green, and the fourth indicator light is blue. The wireless audible and visual alarm module includes a first audible and visual alarm light and a second audible and visual alarm light. The first audible and visual alarm light is a siren, and the second audible and visual alarm light is a horn.

[0008] As a further embodiment of the present invention: a positioning rod is provided on the inner side of the mounting plate, and a positioning hole adapted to the positioning rod is provided on one side of the base frame.

[0009] As a further embodiment of the present invention: a fixing groove is provided on the upper surface of the mounting plate, a connecting plate is provided inside the fixing groove on the outside of the limiting rod, and a spring is sleeved on the outside of the limiting rod above the connecting plate.

[0010] As a further embodiment of the present invention: a limiting hole is formed on the upper surface of the positioning rod, and the end of the limiting rod is embedded in the interior of the limiting hole.

[0011] As a further embodiment of the present invention: the output terminal of the distance sensor is connected to the input terminal of the signal receiving module, and the output terminal of the signal receiving module is connected to the input terminal of the controller.

[0012] As a further aspect of the present invention: the monitoring box is equipped with a camera monitoring module, and the output end of the camera monitoring module is connected to the input end of the controller.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This invention firstly sets up a first photoelectric receiver, a second photoelectric receiver, a third photoelectric receiver, and a fourth photoelectric receiver from front to back on one side of the signal receiving box, and sets up a laser emitting box on one side of the detection wheel. The laser emitted by the laser emitter inside the laser emitting box and the signal received by the different photoelectric receivers can determine the direction of the detection wheel. At the same time, the distance between the detection wheel and the distance sensor can be measured by setting up a distance sensor. Then, the controller can control the first and second sound and light alarms in the wireless sound and light alarm module to emit different sounds, thereby determining the direction of the detection wheel. Finally, the monitoring box can transmit the monitoring image to the controller and transmit it to the display screen in the external monitoring device through the wireless transmission module. In this way, the direction of the detection wheel can be determined by the above multiple methods.

[0015] 2. Pull the pull plate on the upper surface of the mounting plate upwards. This will cause the spring on the outside of the limit rod to deform under pressure. At this time, the positioning rod is inserted into the positioning hole, thus positioning and installing the control box and signal receiver box on the upper surface of the mounting plate. After installation, the pull plate can be released, which will cause the spring to return to its original deformation and the limit rod to be inserted into the limit hole, thus fixing the positioning rod. This setting allows for quick installation of the mounting plate, ensuring the control box and signal receiver box are installed and fixed for easy use. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-7 In this embodiment of the invention, a wheel steering detection device includes a steering rod 1 and a detection wheel 4 disposed on one side of the steering rod 1. A base frame 8 is disposed below the steering rod 1. A mounting plate 6 is mounted on the upper surface of the base frame 8. A pull plate 11 is disposed on the upper surface of the mounting plate 6. A limit rod 13 is mounted on the lower surface of the pull plate 11. A positioning rod 12 is disposed on the inner side of the mounting plate 6. A positioning hole 17 adapted to the positioning rod 12 is opened on one side of the base frame 8. A limit hole 18 is opened on the upper surface of the positioning rod 12. The end of the limit rod 13 is embedded into the interior of the limit hole 18. A fixing groove 15 is opened on the upper surface of the mounting plate 6. A connecting plate 16 is disposed outside the limit rod 13 inside the fixing groove 15. A spring 14 is sleeved on the outside of the limiting rod 13 above the connecting plate 16. Pulling the pull plate 11 on the upper surface of the mounting plate 6 upward will cause the spring 14 on the outside of the limiting rod 13 to be compressed and deformed. At this time, the positioning rod 12 is embedded into the positioning hole 17, so that the control box 2 and the signal receiving box 7 on the upper surface of the mounting plate 6 can be positioned and installed. After installation, the pull plate 11 can be released, which will cause the spring 14 to return to its deformation and the limiting rod 13 to be embedded into the limiting hole 18, thus fixing the positioning rod 12. This setting can quickly install the mounting plate 6 and fix the control box 2 and the signal receiving box 7, making it convenient to use.

[0026] exist Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7In the middle section: On the upper surface of the mounting plate 6, from left to right on one side of the pull plate 11, a control box 2 and a signal receiving box 7 are respectively arranged. A monitoring box 3 is arranged on the upper surface of the signal receiving box 7. A laser emitting box 5 is arranged on one side of the detection wheel 4, and a laser emitter is installed inside the laser emitting box 5. From front to back on one side of the signal receiving box 7, a first photoelectric receiver 9, a second photoelectric receiver 19, a third photoelectric receiver 20, and a fourth photoelectric receiver 21 are respectively arranged. A distance sensor 10 is arranged below the first photoelectric receiver 9 on one side of the signal receiving box 7. From front to back inside the signal receiving box 7, a controller 23 and a signal receiving module 22 are respectively arranged. A wireless transmission module 24 is installed inside the control box 2. The distance sensor... The output of module 10 is connected to the input of signal receiving module 22. The wireless audible and visual alarm module includes a first audible and visual alarm light and a second audible and visual alarm light. The first audible and visual alarm light is a siren sound, and the second audible and visual alarm light is a horn sound. The output of signal receiving module 22 is connected to the input of controller 23. A camera monitoring module is installed inside monitoring box 3. The output of the camera monitoring module is connected to the input of controller 23. The outputs of the first photoelectric receiver 9, the second photoelectric receiver 19, the third photoelectric receiver 20, and the fourth photoelectric receiver 21 are all connected to the input of controller 23. The output of controller 23 is connected to the input of wireless transmission module 24. The output of wireless transmission module 24 is connected to the wireless audible and visual alarm module. The external monitoring display device includes a display screen, a first indicator light, a second indicator light, a third indicator light, and a fourth indicator light. The first indicator light corresponds to the first photoelectric receiver 9, the second indicator light corresponds to the second photoelectric receiver 19, the third indicator light corresponds to the third photoelectric receiver 20, and the fourth indicator light corresponds to the fourth photoelectric receiver 21. The first indicator light is red, the second indicator light is yellow, the third indicator light is green, and the fourth indicator light is blue. The invention firstly places the first photoelectric receiver 9, the second photoelectric receiver 19, the third photoelectric receiver 20, and the fourth photoelectric receiver 21 from front to back on one side of the signal receiving box 7, and then places them on one side of the detection wheel 4. A laser emitting box 5 is provided. The laser emitted by the laser emitter inside the laser emitting box 5 is received by different photoelectric receivers, thereby determining the steering of the detection wheel 4. At the same time, the distance sensor 10 can be set to measure the distance between the detection wheel 4 and the distance sensor 10. Thus, the controller 23 can control the first and second sound and light alarms in the wireless sound and light alarm module to emit different sounds, thereby determining the steering of the detection wheel 4. Finally, the monitoring box 3 can transmit the monitoring image to the controller 23 and transmit it to the display screen in the external monitoring device through the wireless transmission module 24. In this way, the steering of the detection wheel 4 can be determined through the above multiple methods.

[0027] The working principle of this invention is as follows: When in use, the upper surface of the mounting plate 6 is pulled upward by the pull plate 11, which causes the end of the limiting rod 13 to enter the interior of the fixing groove 15. This causes the spring 14, which is sleeved on the outside of the limiting rod 13, to be compressed and deformed. At this time, the mounting plate 6 is installed on the outside of the base frame 8, that is, the positioning rod 12, which is set on the inner side of the mounting plate 6, is embedded in the interior of the positioning hole 17. After the positioning rod 12 is installed, the pull plate 11 is released, which causes the spring 14 to return to its original deformation and causes the end of the limiting rod 13 to be embedded in the interior of the limiting hole 18. This fixes the positioning rod 12. This setting can quickly install the mounting plate 6, so that the control box 2 and the signal receiving box 7 can be installed and fixed, which is convenient for use.

[0028] When determining the steering angle of the detection wheel 4, by turning the detection wheel 4 to the left, the laser emitted by the laser emitter inside the laser emitting box 5 located on one side of the detection wheel 4 will move. That is, the laser will move from the first photoelectric receiver 9 to the second photoelectric receiver 19, and as it continues to rotate, it will move sequentially to the third photoelectric receiver 20 and the fourth photoelectric receiver 21. When it moves to different photoelectric receivers, the indicator lights in the external monitoring display device will display different lights, thereby determining the steering angle of the detection wheel 4. That is, the first photoelectric receiver 9 will cause the first indicator light to light up red, the second photoelectric receiver 19 will cause the second indicator light to light up yellow, the third photoelectric receiver 20 will cause the third indicator light to light up green, and the fourth photoelectric receiver 21 will cause the fourth indicator light to light up blue. In this way, the staff can quickly understand the left turn angle of the wheel.

[0029] Meanwhile, a distance sensor 10 is also provided on one side of the signal receiving box 7. When the detection wheel 4 turns to the left, that is, when the detection wheel 4 and the distance sensor 10 decrease, the signal will be transmitted to the signal receiving module 22. The signal receiving module 22 transmits the signal to the controller 23. The controller 23 can control the first sound and light alarm light in the wireless sound and light alarm module to emit a siren sound through the wireless transmission module 24. The image monitored by the camera monitoring module in the monitoring box 3 is transmitted to the controller 23 and then transmitted to the display screen in the external monitoring device through the wireless transmission module 24.

[0030] When wheel 4 is detected turning to the right, the laser emitted by its laser emitter will move away from the photoelectric receiver, meaning the photoelectric receiver cannot sense the laser. As a result, the indicator light will not illuminate, thus determining that wheel 4 is turning to the right. At the same time, the distance between the distance sensor 10 and wheel 4 will increase, causing the second audible and visual alarm light in the wireless audible and visual alarm module to emit a horn sound. The direction of wheel 4 can be determined based on different sounds. By using these multiple methods to determine the direction of wheel 4, the determination result is more accurate.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
