Description

Technical Field

[0001] This invention relates to the field of vehicle safety technology, specifically to an overload alarm device for automobiles. Background Technology

[0002] Overloading of vehicles is a major drawback of current road transportation. It not only damages road surface facilities, causing road damage, bridge collapse, and a significant reduction in service life, but also easily leads to traffic accidents. The increased weight leads to longer braking distances, ultimately increasing the danger. At the same time, tire deformation caused by overloading can easily cause tire blowouts, rollovers, and sudden swerving, seriously affecting driving safety and causing loss of life and property.

[0003] Currently, the existing technology for detecting vehicle overload is to measure the total load of the vehicle using a large electronic scale. However, large electronic scales are not convenient for detecting the total load of a vehicle. When a vehicle is overloaded, it is not convenient to issue an alarm in time or to determine whether the vehicle is overloaded.

[0004] Therefore, it is necessary to design an overload alarm device for automobiles to solve the above-mentioned problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an overload alarm device for automobiles, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vehicle overload alarm device includes two weighbridges arranged symmetrically. Each weighbridge has two U-shaped grooves, and each U-shaped groove contains a rectangular frame. A lifting mechanism is provided between each rectangular frame and the corresponding U-shaped groove. The lifting mechanism is used to suspend and lift the vehicle.

[0008] Each of the rectangular frames is provided with a mounting plate, and several fixing rods are evenly fixed between each mounting plate and the corresponding rectangular frame. Each mounting plate is equipped with a pressure sensor, and each rectangular frame is fixed with a mounting plate on its top surface. Each mounting plate is in contact with the corresponding pressure sensor. A detection alarm mechanism is provided between the four pressure sensors and the two weighbridge plates. The detection alarm mechanism is used to detect and alarm when a vehicle is overweight.

[0009] Furthermore, each mounting plate has a pair of symmetrical mating rack plates fixed on its bottom surface, and each mating rack plate has a fixed rack plate engaged at its bottom end. Each fixed rack plate is fixed to the inner wall of the U-shaped groove, and each fixed rack plate has a triangular reinforcing plate fixed at its bottom end. Each fixed rack plate is also fixed to the inner wall of the U-shaped groove.

[0010] Furthermore, the lifting mechanism includes four fixed blocks and two movable plates. The two lower fixed blocks are fixedly connected to the U-shaped groove, and the two upper fixed blocks are fixedly connected to the rectangular frame. Each fixed block is movably hinged with a hinge plate, and adjacent hinge plates are movably hinged in a cross manner.

[0011] Both movable plates are located within the U-shaped groove, and the end of each hinged plate away from the corresponding fixed block is movably hinged to the corresponding movable plate. Limiting rods are provided through both sides of each movable plate, and mounting blocks are fixed at both ends of each limiting rod. Each mounting block located below is fixed to the U-shaped groove, and each mounting block located above is fixed to the rectangular frame. A matching adjustment component is provided between the movable plate located below and the U-shaped groove.

[0012] Furthermore, the adjusting assembly includes a telescopic cylinder, which is fixedly installed in the U-shaped groove, and the telescopic end of the telescopic cylinder is fixedly connected to the movable plate located below.

[0013] Furthermore, the detection alarm mechanism includes a mounting frame and an alarm component. The mounting frame is fixedly installed between two weighbridge plates, and a controller is installed inside the mounting frame. Each pressure sensor is electrically connected to the controller via a wire.

[0014] The alarm component is mounted on the top surface of the mounting frame and is electrically connected to the controller via a wire.

[0015] Furthermore, the alarm component includes an audible alarm and an alarm flashing light.

[0016] This invention provides an overload alarm device for automobiles. Compared with the prior art, it has the following advantages:

[0017] This invention, through the coordinated setup of a lifting mechanism and a detection alarm mechanism, suspends and lifts the vehicle, transmitting the vehicle's suspension pressure to a pressure sensor. The pressure sensor then transmits the detected pressure to a controller. A pressure threshold is pre-set in the controller; when the pressure value exceeds the pre-set threshold, the controller activates the alarm component, causing the audible alarm to sound and the alarm flashing light to flash. This effectively solves the problem in existing technologies where it is difficult to issue timely alarms and determine whether a vehicle is overloaded when it is overloaded.

[0026] Example

[0027] To address the technical problems in the background section, the following vehicle overload alarm device is provided:

[0028] Combination Figure 1-5As shown, the present invention provides a vehicle overload alarm device, including two weighbridges 1, which are symmetrically arranged. Each weighbridge 1 has two U-shaped grooves 3, and each U-shaped groove 3 has a rectangular frame 15. Each rectangular frame 15 and the corresponding U-shaped groove 3 are provided with a lifting mechanism, which is used to lift the vehicle in the air.

[0029] Each rectangular frame 15 is equipped with a mounting plate 17. Several fixing rods 16 are evenly fixed between each mounting plate 17 and the corresponding rectangular frame 15. Each mounting plate 17 is equipped with a pressure sensor 11. Each rectangular frame 15 is equipped with a mounting plate 2 on its top surface. Each mounting plate 2 is in contact with the corresponding pressure sensor 11. A detection alarm mechanism is set between the four pressure sensors 11 and the two weighbridge plates 1. The detection alarm mechanism is used to detect and alarm when a vehicle is overweight.

[0030] Each mounting plate 2 has a pair of symmetrical mating rack plates 18 fixed on its bottom surface. Each mating rack plate 18 has a fixed rack plate 7 engaged at its bottom end. Each fixed rack plate 7 is fixed to the inner wall of the U-shaped groove 3. Each fixed rack plate 7 has a triangular reinforcing plate 19 fixed at its bottom end. Each fixed rack plate 7 is fixed to the inner wall of the U-shaped groove 3.

[0031] The lifting mechanism includes four fixed blocks 8 and two movable plates 13. The two fixed blocks 8 located at the bottom are fixedly connected to the U-shaped groove 3, and the two fixed blocks 8 located at the top are fixedly connected to the rectangular frame 15. Each fixed block 8 is movably hinged with a hinge plate 14, and two adjacent hinge plates 14 are cross-hinged.

[0032] Both movable plates 13 are located within the U-shaped groove 3, and the end of each hinged plate 14 furthest from the corresponding fixed block 8 is movably hinged to the corresponding movable plate 13. Limiting rods 10 extend through both sides of each movable plate 13, and mounting blocks 12 are fixed at both ends of each limiting rod 10. Each lower mounting block 12 is fixedly connected to the U-shaped groove 3, and each upper mounting block 12 is fixedly connected to the rectangular frame 15. A matching adjustment assembly is provided between the lower movable plate 13 and the U-shaped groove 3. The matching adjustment assembly includes a telescopic cylinder 9, which is fixedly installed within the U-shaped groove 3, and the telescopic end of the telescopic cylinder 9 is fixedly connected to the lower movable plate 13.

[0033] The detection alarm mechanism includes a mounting frame 5 and an alarm component 4. The mounting frame 5 is fixedly installed between two weighbridge plates 1. A controller 6 is installed inside the mounting frame 5. Each pressure sensor 11 is electrically connected to the controller 6 through a wire 20.

[0034] Alarm component 4 is mounted on the top surface of mounting frame 5 and electrically connected to controller 6 via a wire. Alarm component 4 includes an audible alarm 41 and an alarm flashing light 42.

[0035] Working principle:

[0036] When an overload detection is required for a vehicle, the vehicle is driven onto two weighbridge plates 1, with each tire positioned on its corresponding mounting plate 2. The telescopic cylinder 9 is activated, and its extension end extends or retracts under its power output. This causes the lower movable plate 13 to slide along the two lower limit rods 10. Simultaneously, during the hinge operation, both ends of each hinge plate 14 are hinged along their corresponding fixed blocks 8 and movable plates 13. This causes adjacent, intersecting hinge plates 14 to hinge together via pins, thereby causing the upper movable plate 13 to slide along the two upper limit rods 10. This facilitates the lifting of the mounting plate 2. Since each mounting plate 2 is in contact with the corresponding pressure sensor 11, the vehicle's suspension pressure can be transmitted to the pressure sensor 11 by suspending and lifting the vehicle. The pressure sensor 11 then transmits the detected pressure to the controller 6. A pressure threshold is preset in the controller 6. When the pressure value exceeds the preset pressure threshold, the controller 6 activates the alarm component 4, causing the sound alarm 41 to sound and the alarm flashing light 42 to flash. This effectively solves the problem in the prior art that it is inconvenient to issue an alarm in a timely manner when the vehicle is overloaded, and it is inconvenient to determine whether the vehicle is overloaded.
