[0003] In related technologies, reversing warnings are usually achieved by adding reversing radar and reversing camera systems. However, due to the harsh working environment of mining trucks, with dust and gravel flying everywhere, cameras and reversing radars are easily damaged and accumulate dust. Once damaged, repair costs are high, and the durability of replaced cameras and reversing radars cannot be guaranteed. Moreover, cameras and radars are prone to malfunction when covered in dust, failing to provide timely warnings and unable to provide stable and effective reversing warnings.

[0004] Therefore, it is necessary to research and improve the relevant technologies to provide a mining truck with a mechanical reversing warning device, in order to achieve a more practical purpose. Summary of the Invention

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] To address the shortcomings or deficiencies mentioned in the background technology above, this application provides a mining truck with a mechanical reversing warning device. The device uses a mechanical structure for warning, is simple in structure, can cope with harsh weather, has a low failure rate, and can effectively make up for the lack of adaptability of traditional cameras and reversing images in dusty and gravel conditions.

[0035] See Figures 1 to 8 As shown, this application embodiment provides a mining truck with a mechanical reversing warning device, including:

[0036] The vehicle body 1 has a mounting base 2 at the rear of the vehicle body 1, and a sensor 3 connected to the vehicle controller is mounted on the mounting base 2.

[0037] Trigger arm 4 is rotatably connected to mounting base 2 and is used to rotate around mounting base 2 to move out of the detection range of sensor 3 when an obstacle is triggered.

[0038] The elastic element 5 is connected to the mounting base 2 and the trigger arm 4 at both ends, so that the trigger arm 4 is kept within the detection range of the sensor 3.

[0039] The mining truck with a mechanical reversing warning device in this embodiment of the application is equipped with a trigger arm 4 in conjunction with a sensor 3. After triggering an obstacle, the trigger arm 4 can move out of the detection range of the sensor 3, thereby sending a signal to the vehicle controller to control the vehicle to stop reversing, so as to realize the reversing warning. At the same time, in conjunction with the elastic element 5, the trigger arm 4 can be reset, so that the device returns to the ready-to-use state. It has the advantages of simple structure, low failure rate and no need for frequent maintenance.

[0040] This device solves the problem of providing effective and stable reversing warning for mining trucks under harsh working conditions such as dust and sand in mines. It also overcomes the problem of cameras and reversing radars being easily damaged under harsh working conditions in mines. The device has a simple structure, low failure rate, and can be used stably and effectively under harsh working conditions. It can save on the maintenance costs of mining trucks and ensure driver safety.

[0041] Specifically, the mounting base 2 is installed on the rear of the vehicle frame 1 by fasteners. The end of the mounting base 2 away from the vehicle frame 1 is fixedly equipped with a sensor 3. The sensor 3 is an inductive sensor. The inductive sensor is electrically connected to the vehicle controller to ensure stable signal transmission. When reversing, when the trigger arm 4 is not in contact with an obstacle, the inductive sensor detects the trigger arm 4. At this time, the inductive sensor detects the trigger arm 4 and outputs a high-level signal to the vehicle controller. The vehicle does not issue a warning and the vehicle reverses normally.

[0042] When an obstacle touches trigger arm 4, trigger arm 4 rotates a certain angle. The inductive sensor's detection end is unobstructed, so the inductive sensor does not detect trigger arm 4 and outputs a low-level signal. When the vehicle is in reverse gear, the vehicle controller controls the transmission to return to neutral (N) and brakes the vehicle. The vehicle can only select forward gears. Control returns to normal when the inductive sensor signal returns to a high level. It should be noted that the above process only applies to reverse driving. When shifting into forward gear, whether signal baffle 42 obstructs sensor 3 or not will not trigger an alarm.

[0043] In some alternative embodiments: see Figures 1 to 8 As shown, this application embodiment provides a mining truck with a mechanical reversing warning device. The trigger arm 4 of the mining truck with the mechanical reversing warning device includes a swing plate 41 for triggering obstacles and a baffle 42 for detection by a sensor 3. A bushing 43 is fixedly connected between the swing plate 41 and the baffle 42. The bushing 43 is rotatably connected to the mounting base 2 through a pin 6.

[0044] The mining truck with a mechanical reversing warning device in this embodiment of the application is fixedly connected to the swing plate 41 and the baffle 42 by setting the bushing 43 respectively. The swing plate 41 and the baffle 42 are rigidly connected by the bushing 43, which enhances the structural stability of the trigger arm 4. At the same time, the installation and maintenance are simplified by the rotational cooperation of the pin 6 and the bushing 43, which is suitable for the mining environment with frequent impacts.

[0045] Specifically, the swing plate 41 and the baffle 42 are fixedly connected to the bushing 43 by welding. The pin 6 passes through the bushing 43 and is fixedly connected to the mounting base 2. The bushing 43 and the pin 6 rotate to reduce the frictional resistance between the trigger arm 4 and the mounting base 2, ensuring that the swing plate 41 can rotate quickly when impacted by an obstacle. The baffle 42 simultaneously moves out of the detection range of the sensor 3, triggering a warning signal and stopping the vehicle from reversing. The rotational connection of the bushing 43 also ensures the consistency of movement between the swing plate 41 and the baffle 42, avoiding false triggering or failure due to structural loosening.

[0046] In some alternative embodiments: see Figures 1 to 8As shown, this application embodiment provides a mining truck with a mechanical reversing warning device. The baffle 42 and the swing plate 41 of the mining truck with the mechanical reversing warning device are arranged perpendicularly to each other. The two ends of the elastic member 5 are respectively connected to the swing plate 41 and the mounting base 2. A counterweight 44 is provided on the swing plate 41. The counterweight 44 is used to balance the trigger arm 4 so that the trigger arm 4 is kept in a preset position.

[0047] The mining truck with mechanical reversing warning device in this embodiment optimizes the relative positional relationship between the baffle 42 and the swing plate 41 through a vertical structure design. The counterweight 44 enables the swing plate 41 to balance the elastic force of the elastic element 5, so that the swing plate 41 is stable at a preset vertical angle when no external force is applied. At the same time, the baffle 42 is located within the detection range of the sensor 3, which can avoid false triggering due to vibration or tilting, thereby improving the reliability of the device.

[0048] Specifically, after the baffle 42 is set perpendicular to the swing plate 41, the contact surface of the obstacle formed by the swing plate 41 can maintain the closest vertical angle, improving the detection sensitivity. The counterweight 44 adjusts the weight distribution at the end of the swing plate 41 to balance the gravitational torque of the trigger arm 4, so that it automatically returns to the vertical angle when no external force is applied. This ensures that the baffle 42 is always within the detection range of the sensor 3, reducing the risk of false triggering. After the installation position of the counterweight 44 is confirmed, it is fixed to the swing plate 41 by welding.

[0049] In some alternative embodiments: see Figures 1 to 8 As shown, this application embodiment provides a mining truck with a mechanical reversing warning device. The mounting base 2 of the mining truck with the mechanical reversing warning device includes a mounting plate 21, two symmetrically arranged side plates 22 are fixed on the mounting plate 21, and a top plate 23 is fixed between the two side plates 22. The sensor 3 is installed on the side plate 22 and the detection end is located below the top plate 23.

[0050] The mining truck with mechanical reversing warning device in this embodiment provides a reliable installation space for sensor 3 by setting the mounting structure of side plate 22 and top plate 23. The detection end layout under the top plate 23 can effectively protect sensor 3, while ensuring that trigger arm 4 acts in time after contacting an obstacle.

[0051] Specifically, after the side plate 22 and the top plate 23 are welded and fixed together, they are welded and fixed to the mounting plate 21. The mounting plate 21 is fixed and installed by fasteners. The combined structure of the side plate 22 and the top plate 23 provides an impact-resistant mounting platform for the sensor 3. The layout of the detection end under the top plate 23 can prevent the sensor 3 from being directly exposed to the sand and gravel splash area. When the trigger arm 4 moves due to obstacles, the supporting effect of the top plate 23 and the side plate 22 ensures that the sensor 3 is fixed in position, avoiding signal deviation caused by the vibration of the vehicle body 1.

[0052] In some alternative embodiments: see Figures 1 to 8 As shown, this application embodiment provides a mining truck with a mechanical reversing warning device. The sensor 3 of the mining truck with the mechanical reversing warning device is installed through the side plate 22. The two side plates 22 are respectively equipped with a protective cover 7 to accommodate the sensor 3 on the opposite side. The protective cover 7 is provided with a water leakage hole 71.

[0053] The mining truck with a mechanical reversing warning device in this embodiment of the application provides physical protection for the sensor 3 by setting a protective cover 7 to prevent sand and gravel impact and dust accumulation. The drainage hole 71 is designed to quickly drain rainwater or seepage liquid, avoiding short circuits or signal interference caused by water accumulation in the sensor 3, and significantly extending its service life.

[0054] Specifically, sensor 3 is fixed to side plate 22 by locking nuts, and protective cover 7 is fixedly connected to side plate 22 by fasteners. Protective cover 7 covers the exposed part of sensor 3 on side plate 22, thereby forming a physical isolation layer to block direct impact from sand and gravel. The setting of drainage hole 71 ensures that rainwater or liquid is quickly discharged under the action of gravity, preventing liquid from accumulating in protective cover 7, thereby maintaining the cleanliness of sensor 3 surface and the stability of signal path.

[0055] In some alternative embodiments: see Figures 1 to 8 As shown, this application embodiment provides a mining truck with a mechanical reversing warning device. The elastic element 5 of the mining truck with the mechanical reversing warning device is a tension spring, and the mounting base 2 and the trigger arm 4 are respectively provided with hooks 8 for connecting the tension spring.

[0056] The mining truck with a mechanical reversing warning device in this embodiment uses a tension spring as an elastic element 5 and a hook 8 to achieve rapid reset of the trigger arm 4. At the same time, the tension spring has a simple structure and low cost, which meets the dual requirements of reliability and economy for mining equipment.

[0057] Specifically, the elastic deformation characteristics of the tension spring enable it to provide a stable restoring force when the trigger arm 4 is rotated under force, and the flexible connection of the hook 8 reduces stress concentration; when the obstacle is removed, the tension spring contracts to drive the trigger arm 4 to rotate, the baffle 42 re-enters the detection range of the sensor 3, and the device is restored to the ready-to-use state.

[0058] In some alternative embodiments: see Figures 1 to 8 As shown, this application embodiment provides a mining truck with a mechanical reversing warning device. The sensor 3 of the mining truck with the mechanical reversing warning device is any one of an inductive sensor, a capacitive sensor, a photoelectric sensor, and an ultrasonic sensor.

[0059] The mining truck with a mechanical reversing warning device in this embodiment of the application detects the baffle 42 by setting a sensor 3. The sensor 3 can be compatible with a variety of sensor types and the detection method can be flexibly selected according to the actual working conditions. For example, in a high dust environment, an ultrasonic sensor 3 is preferred to ensure the adaptability and versatility of the warning function.

[0060] It should be noted that different sensor types all achieve signal path blocking or release through the mechanical action of trigger arm 4. For example, photoelectric sensor 3 blocks the light beam through baffle 42, and ultrasonic sensor 3 reflects the signal through baffle 42. The physical blocking method of trigger arm 4 can be flexibly adjusted according to the type of sensor used to ensure the compatibility and flexibility of the device.

[0061] In some alternative embodiments: see Figures 1 to 8 As shown, this application embodiment provides a mining truck with a mechanical reversing warning device. The mining truck with the mechanical reversing warning device also includes a bracket. The bracket includes a crossbeam 9 fixedly connected to the mounting base 2, and connecting seats 10 fixedly connected to both ends of the crossbeam 9 and fixedly connected to the vehicle body 1.

[0062] The mining truck with mechanical reversing warning device in this embodiment of the application uses a bracket structure to firmly connect the mounting base 2 to the frame of the vehicle body 1. The combined design of the crossbeam 9 and the connecting seat 10 enhances the overall impact resistance of the device and adapts to the complex working conditions of bumpy mine roads.

[0063] Specifically, the bracket disperses the vibrations caused by the bumps of the vehicle body 1 through the I-beam support structure of the crossbeam 9 and the connecting seat 10, reducing the risk of deformation of the mounting seat 2; the fixed connection between the connecting seat 10 and the frame of the vehicle body 1 ensures that the trigger arm 4 can maintain its movement trajectory under severe vibration, avoiding functional failure due to structural loosening.

[0064] In some alternative embodiments: see Figures 1 to 8 As shown, this application embodiment provides a mining truck with a mechanical reversing warning device. The connecting seat 10 of the mining truck with the mechanical reversing warning device includes a connecting plate 101 fixedly connected to the vehicle body 1, and a U-shaped plate 102 fixedly connected to the connecting plate 101. A reinforcing plate 103 is fixedly connected to the inner side of the U-shaped plate 102.

[0065] The mining truck with a mechanical reversing warning device in this embodiment improves the rigidity and deformation resistance of the connection between the bracket and the vehicle body 1 by setting a combination structure of U-shaped plate 102 and reinforcing plate 103. At the same time, the modular design facilitates quick installation and disassembly, reducing maintenance costs.

[0066] Specifically, the connecting plate 101 is welded and fixed to the top of the U-shaped plate 102, and multiple spaced reinforcing plates are welded and fixed to the inner side of the U-shaped plate 102. The connecting plate 101 is fixedly connected to the rear of the frame by fasteners, and the crossbeam 9 is fixedly connected to the U-shaped plate 102 by fasteners. The reinforcing plate 103 fills the cavity area inside the U-shaped plate 102, which can effectively resist the lateral impact force on the rear of the vehicle body 1 during mining operations and ensure the long-term stability of the support.

[0067] In some alternative embodiments: see Figures 1 to 8 As shown, this application embodiment provides a mining truck with a mechanical reversing warning device. The crossbeam 9 of the mining truck with the mechanical reversing warning device is fixedly connected to the U-shaped plate 102 by fasteners. The U-shaped plate 102 is provided with a plurality of fastening holes 104 arranged along its length direction.

[0068] The mining truck with mechanical reversing warning device in this embodiment of the application achieves multi-point fixing of the crossbeam 9 and the U-shaped plate 102 through the arrangement design of multiple sets of fastening holes 104, which enhances the structural stability. At the same time, the fasteners adopt standardized selection to ensure the convenience and universality of installation.

[0069] Specifically, multiple sets of fastening holes 104 allow the crossbeam 9 and the U-shaped plate 102 to be rigidly connected in multiple positions, facilitating the adjustment of the relative installation positions of the crossbeam 9 and the U-shaped plate 102. The crossbeam 9 and the U-shaped plate 102 are fastened together by four bolts, which can distribute the stress at the connection and avoid structural deformation caused by uneven local stress. The use of standard fasteners simplifies the installation process and meets the needs of rapid deployment of mining equipment.

[0070] For example, the connecting seat 10 is fixed to the frame of the vehicle body 1 by bolts, and the crossbeam 9 is connected to the connecting seat 10 by bolts. The appropriate height arrangement is achieved by fastening holes 104 at appropriate positions on the matching U-shaped plate 102. The mounting seat 2 is then fixed to the crossbeam 9 by bolts. By changing the installation position of the crossbeam 9 in the height direction, it can adapt to different road conditions.

[0071] Sensor 3 is mounted on side plate 22 by two locking nuts and is covered by a protective cover 7. Sway plate 41 and baffle 42 are fixedly connected together by bushing 43. Bushing 43 is connected to mounting base 2 by a pin 6, allowing sway plate 41 to rotate around mounting base 2. Two elastic elements 5 connect sway plate 41 and mounting base 2 to prevent excessive swaying of sway plate 41 during reversing, which could lead to false alarms, and also to help sway plate 41 return to its original position.

[0072] Specifically, two inductive sensors are installed on both sides of the mounting base 2. When reversing, when the swing plate 41 does not contact the obstacle, there is a baffle 42 in front of the inductive sensor. At this time, the inductive sensor detects the baffle 42 and outputs a high-level signal to the vehicle controller. The vehicle does not issue a warning and the vehicle drives normally.

[0073] When an obstacle contacts the swing plate 41, since the swing plate 41 and the baffle 42 are integrally connected via the bushing 43, the swing plate 41 rotates at a certain angle, which in turn drives the baffle 42 to rotate at a certain angle. At this time, there is no obstruction in front of the inductive sensor, so the inductive sensor does not detect the baffle 42 and outputs a low-level signal to the vehicle controller. When the vehicle is in reverse gear, the vehicle controller controls the transmission to return to neutral (N) and brakes the vehicle to prevent it from rolling backward. At this time, the vehicle can only select forward gears. When the sensor 3 signal returns to a high level, the control returns to normal.
