Description

Technical Field

[0001] This invention belongs to the field of automotive maintenance technology, specifically relating to a cab rollover warning system and method. Background Technology

[0002] Truck cab tilting systems are primarily used in vehicle maintenance. Driven and connected by tilting cylinders, these systems are prone to occasional defects and pose a certain degree of danger during operation. Therefore, no one is allowed to stand in front of or behind the cab during the tilting process. Furthermore, to enhance aesthetics, optimize wind resistance, and maintain external characteristics, the front grille and bumper may interfere with each other during tilting. Since the tilting control mechanism is located at the rear of the cab, it is impossible to observe the front, potentially causing damage to exterior components.

[0003] Meanwhile, the operator of the overturned cab was at the rear of the cab and could not observe the situation of the people in front of the cab. As a result, the cab fell and caused injuries or deaths to the other people.

[0004] In order to effectively solve the above problems, existing technologies usually affix cab tilting signs to the pump body and near the right-side tilting operator of the cab to remind operators to operate according to requirements. Although this has a certain reminder effect, it cannot guarantee that every operator will follow the operating steps completely, so it is still not an effective reminder for personnel.

[0005] Therefore, in order to effectively solve the above problems, it is necessary to develop an effective technical solution. Based on this, this application is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a cab rollover warning system and method to solve the problems in the prior art.

[0007] Therefore, the present invention provides a cab rollover warning system, comprising: A face mask status detection module is disposed at the front face mask position and is used to detect the opening and closing state of the front face mask. A flip reminder module is electrically connected to the mask status detection module and receives a first level signal and a second level signal emitted by the mask status detection module when the mask is in the open state and the closed state. The flip reminder module outputs corresponding first reminder content and second reminder content. The flip circuit includes both the mask status detection module and the flip reminder module, and the flip circuit also includes a flip module for driving the cab to flip.

[0008] In some embodiments, a control circuit is further included, wherein the control circuit is connected to the toggle circuit via a relay; The control circuit includes a positive power supply terminal, a flip control switch, a flip operation button switch, and a negative power supply terminal.

[0009] In some embodiments, the flip circuit includes a second positive power supply terminal, a negative power supply terminal, a mask status detection module, a flip reminder module, and a flip module.

[0010] In some embodiments, the mask status detection module and the flip reminder module are connected via a signal processing module.

[0011] In some embodiments, the mask status detection module includes a Hall sensor and a permanent magnet. The Hall sensor includes three pins, two of which are connected to the positive terminal and the negative terminal of the power supply, and the other pin is connected to the signal processing module to output a level signal.

[0012] In some embodiments, the Hall sensor is mounted on the surface of the body-in-white, the permanent magnet is disposed inside the front cover, and the permanent magnet corresponds to the position of the Hall sensor. A mask lock is provided between the body-in-white and the front cover, wherein the body-in-white is the structural body of the cab.

[0013] In some embodiments, the flip control switch is disposed on the dashboard of the cab, and the flip operation button, the relay, the flip module, and the flip trapezoidal module are disposed on the front wheel rear fender bracket.

[0014] In some embodiments, the flipping module is a flipping pump, the flipping reminder module is a flipping reminder device, and the flipping reminder device is a sound-emitting device and / or a light-emitting device.

[0015] On the other hand, a cab rollover warning method is also provided, including: Detect the open status of the front hood; When the system is powered on, a voice reminder and / or a flashing reminder are triggered based on the detection result of the opening status of the front cover; If the mask is closed, the first reminder message will be played. If the mask is opened, the second reminder will play.

[0016] In some embodiments, the first reminder is "Front cover not open, stop rolling", and the second reminder is "Rolling cab, do not stand around".

[0017] Beneficial effects: This invention, by setting a status detection device at the front cover lock and linking it with a voice reminder system, successfully upgrades the safety reminder for cab rollover from a passive and easily malfunctioning text sign to an active and mandatory sound warning. This not only effectively corrects the operator's mistake of not opening the mask and prevents damage to parts from being squeezed, but also widely covers the blind spots around the cab with sound, promptly alerting nearby personnel to take evasive action.

[0026] The invention will be more readily understood by referring to the following detailed description of preferred embodiments and included examples. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of conflict, the definitions in this specification shall prevail.

[0027] This invention provides a cab rollover warning system and method, which solves the problem that the existing technology only uses text labels to warn during cab rollover, but the effectiveness of this warning method is poor and it is prone to risks. At the same time, during the rollover process, the operator's field of vision is limited, and it is impossible to see that people are walking around in front of the cab or that people are entering the cab from the back side to operate below the cab, which still poses a great risk.

[0028] Therefore, to effectively solve the above problems, the inventive concept of this application is to arrange a Hall sensor 14 near the front cover 2 to detect whether the face mask is open or not, and to output two states through its high and low level signals. A flip reminder device is added to the system as a generating device to convert text reminders into sound reminders. Based on different signals transmitted by the Hall sensor 14, it emits sounds such as "Front cover 2 is not open, stop the cab flip" or "Cabin flip, do not stand nearby," to correct erroneous operations and remind others.

[0029] The Hall sensor 14 and the tilting reminder are connected in parallel with the tilting pump body. When the cab is not tilted, no detection or sound is emitted. When the tilting pump is powered on, the status of the cab mask is detected and feedback is given through sound to correct violations in a timely manner.

[0030] Specifically, please refer to the following embodiments to fully disclose the relevant technology of the present invention.

[0031] like Figure 1-5 As shown, a cab rollover warning system includes: A mask status detection module 1 is disposed at the location of the front cover 2. The mask status detection module 1 is used to detect the open / closed state of the front cover 2. Preferably, the mask status detection module 1 employs a Hall sensor 14. By detecting the open / closed state of the front cover 2, it can prevent the cab from being tilted when the front cover 2 is not open, thus avoiding damage to the front cover 2 and related components. It should be noted that the front cover 2 refers to a large covering panel installed at the very front of the truck cab, located above the front bumper and typically spanning the entire front of the cab. This front cover 2 is mainly used to cover and protect vehicle components such as the radiator and intercooler behind it, and also constitutes part of the vehicle's exterior design. The front cover 2 is usually connected to the cab body-in-white 16 via hinges and locks, and can be manually unlocked and flipped upwards or forwards for access to the engine compartment. The mask status detection module 1 of this invention is used to detect the open or closed state of this front cover 2 relative to the cab body-in-white 16.

[0032] The flip reminder module 3 is electrically connected to the mask status detection module 1 and receives a first level signal and a second level signal from the mask status detection module 1 when the mask 2 is in the open and closed states, respectively. The flip reminder module 3 outputs corresponding first and second reminder content. The flip reminder module 3 is preferably a flip reminder device. The first level signal corresponds to the mask 2 being in the open state. In this state, the flip reminder module 3 outputs the first reminder content. Under the second level signal, the mask 2 is in the closed state. At this time, the operator is reminded that the mask is not open and the flipping operation needs to be stopped immediately. The operation can be resumed after the mask is opened to avoid damage to the parts.

[0033] The tilting circuit 4, the mask status detection module 1, and the tilting reminder module 3 are all installed on the tilting circuit 4, and the tilting circuit 4 also includes a tilting module 5, which drives the cab to tilt. The tilting module 5 is connected in parallel with the tilting reminder module 3 and the mask status detection module 1. When the cab is not tilted, it does not perform detection or emit sound. When the tilting pump is powered on, it detects the mask status in the cab and provides audible feedback to promptly correct any improper operations. The tilting module 5 enables the cab to tilt and lower.

[0034] like Figures 1-3 As shown, in some embodiments, a control circuit 6 is also included, which is connected to the flip circuit 4 via a relay 12. The relay 12 is responsible for the connection between the control circuit 6 and the flip circuit 4. When the control circuit 6 is energized, the relay 12 is energized, the flip circuit 4 is turned on, and the flip operation begins.

[0035] The control circuit 6 includes a positive power supply 7, a flip control switch 8, a flip operation button switch 9, and a negative power supply 10.

[0036] The positive terminal 7 of the power supply connects to the vehicle's power supply, providing power to the control circuit 6. The tilt control switch 8 is a self-locking switch located on the dashboard. The driver can easily close this button while inside the vehicle to prevent accidental tilting of the cab by personnel below. To tilt the cab, simply open this button to power the control system. The tilt operation button switch 9 is located at the rear right side of the cab along with the tilt pump assembly. It is a self-resetting switch; continuous pressing powers the control system, and releasing the button immediately de-energizes the system, stopping all functions. This operation switch meets IP68 waterproof requirements and is encapsulated with relay 12 in a plastic housing using ultrasonic welding to isolate it from external moisture and air, achieving insulation. The negative terminal 10 connects to the negative terminal of the power supply, forming a complete circuit.

[0037] In one embodiment, the flip circuit 4 includes a power positive terminal 11, a power negative terminal 10, a mask status detection module 1, a flip reminder module 3, and a flip module 5. The power positive terminal 11 and the negative terminal are connected to the vehicle's power supply to provide power to the flip circuit 4.

[0038] The mask status detection module 1 is preferably a Hall sensor 14 and a permanent magnet 15, and the flip reminder module 3 is preferably a sound-emitting component, such as a speaker module. In some embodiments, it may also include a light-emitting device that can emit different colors of light to represent different signals and achieve the reminder effect.

[0039] The tilting module 5 includes a tilting pump, which is an electric pump, located on the rear fender of the right front wheel. This application adds a tilting reminder to the original layout, close to the pump's mounting position. The tilting pump's circuitry is equipped with thermal and overload protection components connected in series. After repeated tilting, the electric pump generates significant heat; continued tilting under these conditions could damage its components. The thermal and overload protection components effectively protect the tilting pump. Connecting the thermal protection to the electric pump allows for more sensitive detection of heat sources and timely circuit breaking to protect the pump.

[0040] like Figure 1 and Figure 5 In some embodiments, the mask status detection module 1 and the flip reminder module 3 are connected through the signal processing module 13. The Hall sensor 14 includes three pins, two of which are connected to the positive and negative terminals of the power supply, and the other pin is connected to the signal processing module 13 to output a level signal.

[0041] Specifically, the three pins are VCC, GND, and OUT, where VCC is the power supply port, GND is the ground port, and OUT is the output port, all of which are connected to the flip reminder signal processing module 13.

[0042] In the mask opening detection device, a high level indicates the mask is open, and a low level indicates the mask is closed.

[0043] After the flip circuit 4 is activated, the Hall sensor 14 on the front cover 2 begins detection. If it outputs a high level, it indicates that the cover is open, and the flip reminder speaker module plays "Driver's cab flipped, do not stand nearby." This is to remind other personnel around the vehicle to avoid the driver's cab in time and prevent accidents.

[0044] If the output is low, it indicates that the face mask is closed, and the flip-over reminder speaker module will play "Front face mask 2 not open, stop flipping the cab." This serves as a reminder to the operator that the face mask is not open and that the flipping operation must be stopped immediately. The operator should wait until the face mask is open before resuming the operation to avoid damage to components.

[0045] like Figure 4 As shown, in one embodiment, a Hall sensor 14 is mounted on the surface of the body-in-white 16, a permanent magnet 15 is disposed inside the front cover 2, and the permanent magnet 15 corresponds to the position of the Hall sensor 14. A mask lock 17 is provided between the body-in-white 16 and the front cover 2. The body-in-white 16 is the structural body of the cab. The body-in-white 16 is the cab structural body that has been welded but has not yet been painted or fitted with accessories, providing a stable mounting reference for the frame and skin of the cab.

[0046] By fixing the Hall sensor 14 to the body-in-white 16, which is the structural body, a solid and immovable measurement reference is provided, avoiding misjudgment of detection signals caused by component shaking, thereby ensuring high reliability of condition detection.

[0047] Specifically, when the face mask 2 is fastened by the face mask lock 17, the permanent magnet 15 fixed inside it comes into close proximity to the Hall sensor 14 fixed on the body-in-white 16. The Hall sensor 14 senses the strong magnetic field, and its signal output terminal (OUT) outputs a low-level signal to the flip reminder.

[0048] When the operator unlocks the mask lock 17 and flips up the front mask 2, the permanent magnet 15 moves away from the Hall sensor 14 along with the front mask 2. The magnetic field strength sensed by the Hall sensor 14 decreases sharply, and the output level of its signal output terminal (OUT) changes from low level to high level signal, which is then transmitted to the flip reminder.

[0049] The logic processing module inside the flip reminder accurately determines the real-time status of the front cover 2 based on the received level signal, and drives the voice module to play the corresponding safety prompt voice accordingly.

[0050] In one embodiment, the flip module 5 is a flip pump, and the flip reminder module 3 is a flip reminder device, which is a sound-emitting device and / or a light-emitting device. The light-emitting device can be a high-brightness LED. This LED can be designed as a dual-color LED (red and yellow) and linked to the voice playback logic via a control circuit.

[0051] When the system detects that the mask is not open, it will play the corresponding voice message and drive the LED to flash red light to strongly visually warn the operator to stop immediately.

[0052] When the face mask is detected to be open, the LED light will flash yellow to warn nearby personnel to take cover. The LED light can be mounted on the main body of the warning device or routed separately to a more easily observable location such as the side or rear of the driver's cab via wiring harness.

[0053] like Figure 6 As shown, on the other hand, a cab rollover warning method is also provided, specifically including: Detect the open status of the front cover 2; When the system is powered on, voice reminders and / or flashing reminders are triggered based on the detection result of the open status of the front cover 2, that is, the two reminder methods can work independently or simultaneously; If the mask is closed, the first reminder message will be played. If the face mask is opened, a second warning message will be played. The first warning message is "Front face mask 2 is not open, stop rotating," and the second warning message is "The cab is rotating, do not stand around." In some embodiments, the first warning message may also be a flashing red light, and the second warning message may be a flashing yellow light.

[0054] This method upgrades safety alerts from passive text labels to proactive audio-visual signals, forcing operators and those in the vicinity to receive warning information, effectively overcoming the problem of alerts failing due to dirty, faded, or ignored labels.

[0055] Simultaneously, the robustness and applicability of the solution are greatly enhanced by employing voice and / or flashing alert modes. In noisy environments, the light signal ensures effective alerts, while the voice signal is more prominent in situations requiring quiet or in low-light conditions. The combination of both achieves the strongest warning effect, ensuring no blind spots in alerts.

[0056] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
