Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction safety protection, and in particular to a safety collision warning device for construction vehicles. Background Technology
[0002] Construction vehicles such as excavators and loaders often reverse or move in narrow and complex working environments, creating huge blind spots. Traditional methods relying on rearview mirrors and manual observation are insufficient to ensure comprehensive safety, making collisions highly likely and causing personal injury and equipment damage. Existing warning devices are mostly simple reversing radars or cameras, which often require drilling or welding for installation, potentially damaging the vehicle's original structure and making them inconvenient to move and reuse. At the same time, these devices usually only provide audible and visual alarms and lack a physical buffer protection mechanism in the event of an unavoidable collision, making it difficult to effectively mitigate the damage caused by the impact.
[0003] Therefore, in order to address the above problems, a safety collision warning device for construction vehicles is now being developed. Utility Model Content
[0004] To overcome the shortcomings of existing warning devices, which are mostly simple reversing radars or cameras, whose installation often requires drilling or welding, potentially damaging the original vehicle structure and making them inconvenient to transfer and reuse, and which typically only provide audible and visual alarms and lack a physical buffer protection mechanism in the event of an unavoidable collision, making it difficult to effectively mitigate the damage caused by the impact, this utility model provides a construction vehicle safety collision warning device.
[0005] The technical solution of this utility model is:
[0006] A construction vehicle safety collision warning device includes four mounting components. Each mounting component has a fixing component on its upper front side. Each fixing component has a rotatable buckle. The buckle has a protrusion on its rear side to facilitate the operator to move the buckle. A torsion spring connects the buckle and the fixing component. A mounting frame is placed between the fixing components. The buckle is used to further fix the mounting frame.
[0007] Furthermore, it also includes an alarm, the top of which is provided with a hook that can be engaged with the mounting bracket, and a ranging radar is provided in the middle of the alarm.
[0008] Furthermore, it also includes dampers, which are installed on the front sides of the left and right sides of the mounting frame, with a total of four dampers. A collision protection frame is provided between the dampers, and four springs are provided between the collision protection frame and the mounting frame. The springs are sleeved on the corresponding dampers.
[0009] Furthermore, all of the fasteners are J-shaped structures.
[0010] Furthermore, the fastener has a nut on its rear side for securing the fastener.
[0011] Furthermore, the front side of the anti-collision frame has a sloping structure.
[0012] By adopting the above technical solution, the beneficial effects of this utility model are as follows:
[0013] This utility model achieves rapid and secure installation and non-destructive disassembly of the mounting bracket through J-type fasteners and reverse buckles, facilitating transfer and use between different vehicles; the integrated high-precision millimeter-wave radar can effectively detect obstacles in blind spots and link with audible and visual alarms for multi-level early warning, greatly improving situational awareness; the spring damper and inclined anti-collision frame structure can actively absorb energy and buffer in the event of a collision, significantly reducing the impact force, thereby comprehensively improving the safety of construction vehicle operations and protecting personnel and equipment assets.

[0019] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.
[0020] A construction vehicle safety collision warning device, such as Figures 1-4As shown, the device includes four mounting components 1. Each mounting component 1 has a fixing component 2 on its upper front side. The fixing components 2 are all J-shaped structures. The fixing components 2 have nuts on their rear sides for fixing. Each fixing component 2 has a rotating buckle 3. The buckle 3 has a protrusion 31 on its rear side for easy operation. A torsion spring 32 connects the buckle 3 to the fixing component 2. A mounting bracket 4 is placed between the fixing components 2. The buckle 3 is used to further fix the mounting bracket 4. The alarm 5 has a hook 6 on its top. The hook 6 can engage with the mounting bracket 4. A ranging radar is located in the middle of the alarm 5. There are four dampers 9 installed on the left and right front sides of the mounting bracket 4. A crash barrier 7 is installed between the dampers 9. The front side of the crash barrier 7 is a sloping structure. Four springs 8 are installed between the crash barrier 7 and the mounting bracket 4. The springs 8 are sleeved on the corresponding dampers 9.
[0021] It should be noted that, firstly, the operator uses four mounting brackets 1 to fix the entire device to a suitable position at the rear or front of the vehicle. Then, using the J-shaped fastener 2 and its rear nut, the mounting bracket 4 is initially secured to the vehicle's frame or bumper. Subsequently, by controlling the rotation of the control lug 31 and the reverse buckle 3, it is firmly locked onto the mounting bracket 4, forming a double mechanical lock. This ensures that the mounting bracket 4 will not loosen or fall off during vehicle movement or vibration, providing a stable and reliable mounting base for subsequent functional components. The alarm 5 is conveniently attached to the mounting bracket 4 via the top hook 6, enabling quick installation and removal for maintenance or replacement. The alarm 5 integrates a ranging radar. (Using a millimeter-wave radar with strong anti-interference capabilities and high detection accuracy, specifically model SRR306-21A) It is responsible for continuously transmitting high-frequency electromagnetic waves into space and receiving echoes. By calculating the round-trip time of the beam, it accurately calculates the real-time distance and relative speed of obstacles behind the vehicle. The data detected by the radar is transmitted in real time to the central processing unit of the alarm 5 through the internal circuit. The processor makes logical judgments based on the preset safety thresholds (set to three meters for warning and two meters for emergency alarm), thereby driving the sound and light alarm system. When an obstacle enters the warning range, the alarm 5 emits an intermittent buzzing sound and flashing lights to remind the driver and personnel to pay attention.
[0022] When the distance is further reduced to the danger zone, the alarm immediately escalates to a continuous high-frequency sound and flashing lights, creating a strong visual and auditory warning to maximize reaction time. If the warning fails to prevent a collision, the four dampers 9 installed on the left and right front sides of the mounting bracket 4, together with the springs 8 mounted on them, form an energy absorption system. When the front inclined structure anti-collision frame 7 is impacted, the impact force first pushes the anti-collision frame 7 backward, then compresses the springs 8 and forces the piston rods of the dampers 9 to move. The dampers 9 effectively dissipate the collision kinetic energy through the throttling effect of internal hydraulic oil or gas, while the springs 8 provide buffering and restoring force. The two work together to transform the instantaneous violent impact into a controllable and gradual buffering movement, significantly reducing the impact acceleration, thereby protecting the vehicle body, the internal electronic components of the anti-collision device, and the collision object, achieving full-process safety assurance from warning to passive protection.
[0023] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
