[0025] Please refer to Figures 1 to 3 The present invention provides an anti-collision component, which is arranged between a frame assembly 200 and a rear axle assembly 300. The anti-collision component includes: an anti-collision member 11 and at least one anti-collision column 17. At least part of the end surface of the anti-collision member 11 is an arcuate surface. The arcuate surface of the anti-collision member 11 is used to abut against the frame assembly 200. The anti-collision member 11 is connected to the rear axle assembly 300. An axial end surface of the anti-collision column 17 abuts against the frame assembly 200. The anti-collision column 17 can be movably inserted into the anti-collision member 11 along the axial direction of the anti-collision column 17 so that the other axial end surface of the anti-collision column 17 abuts against the rear axle assembly 300.

[0026] The anti-collision assembly of the present invention includes an anti-collision member 11 and at least one anti-collision column 17. At least part of the end surface of the anti-collision member 11 is an arc-shaped surface. The anti-collision member 11 is connected to the rear axle assembly 300. The anti-collision column 17 is movably arranged on the anti-collision member 11 along the axial direction of the anti-collision column 17. When the frame assembly 200 moves toward the direction close to the rear axle assembly 300, the frame assembly 200 squeezes the anti-collision column 17, so that the anti-collision column 17 moves to the other axial end surface of the anti-collision column 17 and the rear axle assembly 300. When the anti-collision member 11 abuts against the frame assembly 200, the anti-collision member 11 and the anti-collision column 17 jointly prevent the frame assembly 200 from continuing to move toward the direction close to the rear axle assembly 300, thereby ensuring a sufficient safety distance between the frame assembly 200 and the rear axle assembly 300, and avoiding a safety distance that is too small, resulting in the rear suspension cylinder being subjected to a rigid collision between the frame assembly and the rear axle assembly, thereby solving the problem of malfunction of the off-road mining dump truck caused by damage to the rear suspension cylinder in the prior art.

[0027] In this embodiment, the anti-collision member 11 and the anti-collision column 17 are clearance-fitted.

[0028] Specifically, such a configuration ensures that the anti-collision column 17 can move freely relative to the anti-collision component 11 along the axial direction of the anti-collision column 17, and ensures that the frame assembly 200 will squeeze the anti-collision column 17 to move until the other axial end face of the anti-collision column 17 abuts against the rear axle assembly 300. This design allows the anti-collision component to absorb and disperse the collision impact force between the rear axle assembly 300 and the frame assembly 200 during vehicle driving.

[0029] In this embodiment, a through hole 131 is provided on the anti-collision member 11 . The through hole 131 extends along the axial direction of the anti-collision column 17 . The diameter of the through hole 131 is greater than the diameter of the anti-collision column 17 .

[0030] Specifically, such a configuration further ensures that the anti-collision column 17 can move freely relative to the anti-collision member 11 along the axial direction of the anti-collision column 17, thereby avoiding synchronous movement of the anti-collision column 17 and the anti-collision member 11, which causes the anti-collision member 11 to be unable to buffer the frame assembly 200.

[0031] In this embodiment, the anti-collision component 11 includes an anti-collision body 14 and a connecting portion 15 which are sequentially arranged along the depth direction of the anti-collision component 11, and the connecting portion 15 is used to connect with the rear axle assembly 300. The anti-collision body 14 includes a first anti-collision surface 12 and a second anti-collision surface 13 which are relatively arranged along the depth direction of the anti-collision component 11. The first anti-collision surface 12 is an arc-shaped surface, and the first anti-collision surface 12 is used to abut against the frame assembly 200, and the second anti-collision surface 13 is used to connect with the connecting portion 15; wherein, the depth direction of the anti-collision component 11 is parallel to the axial direction of the anti-collision column 17.

[0032] Specifically, by setting the first anti-collision surface 12 to abut against the frame assembly 200, the anti-collision component 11 can buffer the impact force applied by the frame assembly 200 to the rear axle assembly 300, effectively ensuring that there is a sufficient safety distance between the frame assembly 200 and the rear axle assembly 300; by setting the second anti-collision surface 13 to be connected to the connecting portion 15, the reliable connection between the connecting portion 15 and the anti-collision body 14 and the structural integrity of the anti-collision component 11 are ensured.

[0033] In this embodiment, from the radial direction of the through hole 131, from the circumferential edge of the first anti-collision surface 12 to the center axis of the anti-collision component 11, the distance between the first anti-collision surface 12 and the second anti-collision surface 13 in the depth direction of the anti-collision component 11 gradually increases.

[0034] Specifically, such a configuration enables the anti-collision component 11 to further disperse the impact force through the deformation of the first anti-collision surface 12 when impacted by the frame assembly 200, thereby enhancing the anti-collision flexibility and anti-collision and impact absorption capabilities of the anti-collision component.

[0035] Specifically, two ends of the anti-collision column 17 pass through the first anti-collision surface 12 and the second anti-collision surface 13 respectively.

[0036] In this embodiment, a groove 16 is provided on the connecting portion 15, and the groove 16 is recessed along the depth direction of the anti-collision component 11 toward the direction close to the first anti-collision surface 12, and the bottom surface of the groove 16 is an arc-shaped surface. A protrusion block 301 is provided on the rear axle assembly 300, and the groove 16 and the protrusion block 301 are adapted to each other so that the protrusion block 301 can be inserted into the groove 16 to connect the anti-collision component 11 and the rear axle assembly 300; wherein, there is an avoidance gap between the protrusion block 301 and the bottom surface of the groove 16.

[0037] Specifically, by setting an avoidance gap between the protrusion block 301 and the bottom surface of the groove 16, the anti-collision column 17 is allowed to undergo a slight displacement relative to the anti-collision component 11 when squeezed by the frame assembly 200, thereby further improving the shock absorption effect of the anti-collision component; by inserting the protrusion block 301 into the groove 16, a firm connection between the anti-collision component 11 and the rear axle assembly 300 is achieved.

[0038] In this embodiment, along the radial direction of the through hole 131, from the edge of the bottom surface of the groove 16 to the direction of the center axis of the anti-collision member 11, the distance between the second anti-collision surface 13 and the bottom surface of the groove 16 along the depth direction of the anti-collision member 11 gradually increases.

[0039] Specifically, such a configuration enables the anti-collision member 11 to further disperse the impact force through the deformation of the bottom surface of the groove 16 when it is impacted by the frame assembly 200, thereby enhancing the anti-collision flexibility and anti-collision impact absorption capability of the anti-collision member 11.

[0040] In this embodiment, there are a plurality of anti-collision columns 17 , and the plurality of anti-collision columns 17 are disposed on the anti-collision member 11 at intervals.

[0041] Specifically, by providing a plurality of anti-collision columns 17, the impact force of the frame assembly 200 can be more evenly dispersed, thereby improving the anti-collision stability and reliability of the anti-collision assembly.

[0042] In this embodiment, the anti-collision member 11 and the anti-collision column 17 are both made of elastic material.

[0043] Specifically, the anti-collision member 11 and the anti-collision column 17 made of elastic material not only provide good impact absorption capacity, but also significantly reduce the noise and vibration generated by the vehicle during driving. Especially in long-term and high-intensity mining transportation operations, this design can significantly improve the driver's working environment and driving comfort.

[0044] The present invention provides an off-road mining dump truck, comprising a frame assembly 200, a rear axle assembly 300, a rear suspension cylinder assembly and the above-mentioned anti-collision component.

[0045] The off-road mining dump truck of the present invention comprises a frame assembly 200 , a rear axle assembly 300 , a rear suspension cylinder assembly 400 and the above-mentioned anti-collision component, wherein the rear suspension cylinder assembly 400 is arranged between the frame assembly 200 and the rear axle assembly 300 .

[0046] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0047] The anti-collision assembly of the present invention includes an anti-collision member 11 and at least one anti-collision column 17. At least part of the end surface of the anti-collision member 11 is an arc-shaped surface. The anti-collision member 11 is connected to the rear axle assembly 300. The anti-collision column 17 is movably arranged on the anti-collision member 11 along the axial direction of the anti-collision column 17. When the frame assembly 200 moves toward the direction close to the rear axle assembly 300, the frame assembly 200 squeezes the anti-collision column 17, so that the anti-collision column 17 moves to the other axial end surface of the anti-collision column 17 and the rear axle assembly 300. When the anti-collision member 11 abuts against the frame assembly 200, the anti-collision member 11 and the anti-collision column 17 jointly prevent the frame assembly 200 from continuing to move toward the direction close to the rear axle assembly 300, thereby ensuring a sufficient safety distance between the frame assembly 200 and the rear axle assembly 300, and avoiding a safety distance that is too small, resulting in the rear suspension cylinder being subjected to a rigid collision between the frame assembly and the rear axle assembly, thereby solving the problem of malfunction of the off-road mining dump truck caused by damage to the rear suspension cylinder in the prior art.
