Description

Technical Field

[0001] This utility model belongs to the field of mining truck technology, specifically relating to a reversing anti-collision mechanism for a non-road mining dump truck. Background Technology

[0002] Non-road mining dump trucks are mainly used in complex environments such as mines, where road conditions are poor. In addition, non-road mining dump trucks are large in size and have many blind spots, making it difficult to detect obstacles in time when reversing.

[0003] To overcome this deficiency and avoid vehicle damage, existing collision avoidance technologies generally include lidar or camera image recognition. However, these technologies not only have problems such as high product prices, limited recognition range, slow response speed and judgment errors, but also the failure of these products due to sludge generated by rainwater or dust removal mist combined with dust. Therefore, these products are not cost-effective in the use of off-road mining dump trucks and are not easy to promote on a large scale. Utility Model Content

[0004] This utility model provides a reversing anti-collision mechanism for non-road mining dump trucks, which solves the technical problem that existing laser radar or camera image recognition technologies are not cost-effective in the harsh operating environment of non-road mining dump trucks. This utility model includes at least one anti-collision component, the anti-collision component comprising: The fixing plate is installed on the outer side of the rear bumper beam of the non-road mining dump truck; Top guard plate, provided on the fixed plate; At least one fixed side plate is disposed on the fixed plate and located on the side of the top guard plate; A switch bracket is mounted on the fixed side plate; The switch is mounted on the switch bracket; An alarm device is installed in the cab of the off-road mining dump truck, and the switch is electrically connected to the alarm device. A movable shaft is rotatably mounted on the fixed side plate, and the movable shaft is located in front of the switch.

[0005] In application, the movable shaft of this invention will first contact the obstacle, causing the movable shaft to rotate and trigger the switch to achieve the purpose of alarm.

[0006] Furthermore, there are two fixed side plates, which are respectively located on both sides of the top guard plate. The beneficial effect of this step is that the fixed side plates can protect the internal switches and movable shafts from impacts by debris from both sides.

[0007] Furthermore, the movable shaft has a thickened head at one end near the switch and a ball head at the other end. The advantages of this step are: the thickened head ensures the reliability of the trigger switch, the ball head increases the contact area between the movable shaft and the obstacle, improves the trigger rate, and the ball head increases the weight, ensuring that the movable shaft remains in a drooping state when it does not touch the obstacle, thus avoiding accidental activation of the switch.

[0008] Furthermore: When there are two or more anti-collision components, a connecting rod is provided between the ball heads. The beneficial effect of this step is that the point contact of the ball heads is changed to the line contact of the connecting rod, which increases the contact area with the obstacle and avoids the movable shaft from being misaligned with the obstacle, thus achieving the purpose of obstacle avoidance and alarm.

[0009] Furthermore: the movable shaft includes a rotating shaft and a movable rod, the rotating shaft is fixed on the fixed side plate, and the rotating shaft passes through the rod body of the movable rod; A tension spring is provided between the movable rod and the top guard plate, and the connection point between the tension spring and the movable rod is located above the rotating shaft. The beneficial effect of this step is that the movable rod is held in place by the tension spring to prevent the movable rod from failing to reset and accidentally triggering the switch.

[0010] Furthermore, a limiting rod is also provided on the fixed side plate. The beneficial effect of this step is that the limiting rod prevents the movable shaft from rotating too much, which could damage the switch.

[0011] Furthermore, the fixed plate is also provided with a bottom limiting protective plate, which is located below the fixed side plate. The bottom limiting protective plate has a limiting waist hole, through which the movable shaft passes. The beneficial effects of this step are: the limiting waist hole can prevent the movable shaft from rotating too much, causing damage to the switch, and the bottom limiting protective plate can also form a relatively closed structure with the fixed side plate and the top protective plate, preventing debris, dust, etc. from adversely affecting the switch and the movable shaft, thereby improving the service life and reliability of the switch and the movable shaft.

[0012] The beneficial effects of this utility model are: 1. This utility model converts mechanical transmission into electrical signals through a mechanical structure and transmits them to the vehicle controller, thereby enabling the vehicle to stop promptly after encountering an obstacle while reversing. 2. This utility model is mainly based on mechanical structure, which is simple, reliable, low in cost, and has a timely response, thus having a high cost performance. Attached Figure Description

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0019] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0021] Implementation of this application, for example Figure 1 As shown, this application provides a reversing anti-collision mechanism for a non-road mining dump truck.

[0022] This application includes at least one anti-collision component, said anti-collision component comprising: Fixed plate 3 is installed on the outer side of the rear anti-collision beam of the non-road mining dump truck, and can generally be connected by welding or U-bolts. Top protective plate 5 is provided on the fixed plate 3; At least one fixed side plate 4 is provided on the fixed plate 3 and located on the side of the top guard plate 5; The switch bracket 2 is mounted on the fixed side plate 4; Switch 1 is mounted on the switch bracket 2; An alarm device is installed in the cab of the non-road mining dump truck. The switch 1 is electrically connected to the alarm device. Taking a non-road mining dump truck model using a new energy vehicle (electric drive) as an example, the new energy vehicle model has a VCU (vehicle control unit), which can control the drive motor to brake and stop the vehicle. Therefore, the alarm device includes a VCU and an indicator light or buzzer added to the instrument panel. The indicator light or buzzer receives the signal sent by the VCU and executes the alarm. The movable shaft 6 is rotatably mounted on the fixed side plate 4, and the movable shaft 6 is located in front of the switch 1.

[0023] In application, the movable shaft 6 of this invention will first contact the obstacle, causing the movable shaft 6 to rotate under force, thereby triggering the switch 1 to achieve the purpose of alarm.

[0024] Switch 1 can be a contact switch or a non-contact switch. The contact switch can be a micro switch or a push button switch, etc., and the non-contact switch can be a proximity switch, etc. If the movable shaft 6 is within 0~15mm of the proximity switch, it can trigger the response of switch 1.

[0025] Based on the above technical solution, there are two fixed side plates 4, which are respectively provided on both sides of the top guard plate 5. The fixed side plates 4 can protect the internal switch 1 and movable shaft 6 from the sides to prevent them from being impacted by debris.

[0026] Based on the above technical solution, the movable shaft 6 is provided with a thickened head at one end near the switch 1 and a ball head at the other end. The thickened head can ensure the reliability of triggering the switch 1, while the ball head increases the contact area between the movable shaft 6 and the obstacle, improves the triggering rate, and the ball head can increase the weight, ensuring that the movable shaft 6 remains in a drooping state when it does not touch the obstacle, thus avoiding accidental activation of the switch 1.

[0027] Based on the above technical solution, when there are two or more anti-collision components, a connecting rod is provided between the ball heads, changing the point contact of the ball heads to the line contact of the connecting rod, increasing the contact area with the obstacle, and preventing the movable shaft 6 from being misaligned with the obstacle, thus failing to achieve the purpose of obstacle avoidance and alarm.

[0028] Based on the above technical solution, the movable shaft 6 includes a rotating shaft and a movable rod. The rotating shaft is fixed on the fixed side plate 4, and the rotating shaft passes through the rod body of the movable rod. A tension spring is provided between the movable rod and the top guard plate 5, and the connection point between the tension spring and the movable rod is located above the rotating shaft. The tension spring pulls the movable rod, keeping the movable shaft rod 6 away from the switch 1 when it is not in contact with an obstacle, so as to avoid accidental activation of the switch. When the movable shaft rod 6 is separated from the obstacle, it can reset as soon as possible after the force is released, thus canceling the alarm.

[0029] Based on the above technical solution, the fixed side plate 4 is also provided with a limiting rod. The limiting rod cooperates with the rotation shaft of the movable shaft 6 to control the rotation amplitude of the movable shaft 6, so that it can only contact or approach the switch 1, and avoid the movable shaft 6 from rotating too much, causing damage to the switch 1.

[0030] Based on the above technical solution, the fixed plate 3 is also provided with a bottom limiting protective plate 7. The bottom limiting protective plate 7 is located below the fixed side plate 4. The bottom limiting protective plate 7 has a limiting waist hole. The movable shaft 6 passes through the limiting waist hole. The limiting waist hole can prevent the movable shaft 6 from rotating too much, which could damage the switch 1. In addition, the bottom limiting protective plate 7 can also form a relatively closed structure with the fixed side plate 4 and the top protective plate 5, which can prevent debris, dust and other things from having an adverse effect on the switch 1 and the movable shaft 6, and can improve the service life and reliability of the switch 1 and the movable shaft 6.

[0031] As mentioned above, the main body of the anti-collision components is a mechanical structure, which can provide a highly reliable anti-collision effect at low cost and does not have strict requirements on the usage environment.
