Description

Technical Field

[0001] The utility model belongs to the technical field of dump trucks, and specifically relates to a rear bumper protection assembly for a dump truck. Background Art

[0002] A dump truck refers to a vehicle that can unload goods by hydraulic or mechanical lifting. It is also called a tipping truck and is composed of components such as an automobile chassis, a hydraulic lifting mechanism, a cargo box, and a power take-off device. The chassis of a dump truck is relatively high, and the rear compartment protrudes backward more. Therefore, a rear bumper protection assembly is provided at the rear of the dump truck. When a small vehicle in the rear has a rear-end collision accident, it forms protection for the rear part of the vehicle and the rear vehicle. When the structural strength and protection performance of the rear bumper protection assembly cannot resist the impact of the rear vehicle, it will cause the small vehicle in the rear to drill under the dump truck, resulting in greater damage to the A-pillar of the small vehicle by the dump truck compartment and causing a relatively large safety accident. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a rear bumper protection assembly for a dump truck aiming at the above defects, which has high structural strength and good protection performance, forms effective protection for the rear part of the vehicle and the rear vehicle, and prevents the rear vehicle from drilling under the vehicle.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows: A rear bumper protection assembly for a dump truck includes an upper mounting plate. Two vertically downward vertical anti-collision beams are symmetrically arranged at the bottom end of the upper mounting plate. A support beam arranged horizontally is provided on the rear end face of the two vertical anti-collision beams. The support beam is perpendicular to the vertical anti-collision beams. A rear mounting plate is provided at one end of the support beam far away from the vertical anti-collision beam. A horizontal anti-collision beam perpendicular to the vertical anti-collision beam is provided at the bottom end of the vertical anti-collision beam. The horizontal anti-collision beam and the vertical anti-collision beam form an L-shaped structure. A protection energy absorption component for connecting between the two horizontal anti-collision beams is provided on the front end face of the two horizontal anti-collision beams. A first structural strengthening component is provided between the top end of the support beam and the rear end face of the vertical anti-collision beam. A second structural strengthening component is provided between the bottom end of the support beam and the horizontal anti-collision beam.

[0005] Further, the protection energy absorption component includes a protection housing, a support plate, and a compression body. The protection housing is in a rectangular structure. The rear end face of the protection housing is connected to the two horizontal anti-collision beams. The support plates are arranged at intervals along the length direction of the protection housing inside the protection housing. The compression body is arranged between adjacent support plates. The compression body is composed of two symmetrically arranged and connected semi-cylinders. The open ends of the two semi-cylinders are respectively connected to the inner walls at both ends of the protection housing.

[0006] Further, the first structural strengthening component includes a first connecting portion, a second connecting portion, and a first inclined portion. The first connecting portion and the second connecting portion are symmetrically arranged at both ends of the first inclined portion. The first connecting portion is connected to the top end of the support beam, and the second connecting portion is connected to the rear end face of the vertical anti-collision beam. A triangular stable structure is formed among the first inclined portion, the support beam, and the vertical anti-collision beam.

[0007] Further, the second structural strengthening component includes a third connecting portion, a fourth connecting portion, and a second inclined portion. The third connecting portion and the fourth connecting portion are symmetrically arranged at both ends of the second inclined portion. The third connecting portion is connected to the bottom end of the support beam, and the fourth connecting portion is connected to the rear end face of the horizontal anti-collision beam. A triangular stable structure is formed among the second inclined portion, the support beam, and the horizontal anti-collision beam.

[0008] Further, reinforcing ribs are arranged in a crosswise manner on the outer surfaces of the vertical anti-collision beam, the support beam, and the horizontal anti-collision beam.

[0009] Further, there are an upper reinforcing rod and a lower reinforcing rod between the two vertical anti-collision beams. The upper reinforcing rod and the lower reinforcing rod are horizontally arranged up and down, and a vertical intermediate reinforcing rod is arranged between the upper reinforcing rod and the lower reinforcing rod.

[0010] The beneficial effects of the present utility model are as follows:

[0011] Through the cooperative setting of the upper mounting plate, the two vertical anti-collision beams, the support beam, the horizontal anti-collision beam, the protective energy-absorbing component, the first structural strengthening component, the second structural strengthening component, and the rear mounting plate, when a collision occurs from the rear, the protective energy-absorbing component first resists and releases the impact, and then transfers it to the horizontal anti-collision beam.

[0017] The following further describes the utility model with reference to the accompanying drawings.

[0018] Refer to Figures 1-3 As shown, the rear bumper protection assembly of the dump truck includes an upper mounting plate 1. The upper mounting plate 1 is fixedly connected to the vehicle by bolts. Two vertical anti-collision beams 2 in a vertically downward state are symmetrically arranged at the bottom end of the upper mounting plate 1. A support beam 3 arranged horizontally is provided on the rear end face of the two vertical anti-collision beams 2. The support beam 3 is perpendicular to the vertical anti-collision beam 2. A rear mounting plate 4 is provided at one end of the support beam 3 away from the vertical anti-collision beam 2. The rear mounting plate 4 is fixedly connected to the vehicle by bolts. The support beam 3 supports the vertical anti-collision beam 2, increasing the structural stability of the vertical anti-collision beam 3 and preventing it from deforming and collapsing backward. A horizontal anti-collision beam 5 perpendicular to the vertical anti-collision beam 2 is provided at the bottom end of the vertical anti-collision beam 2. The front end face of the horizontal anti-collision beam 5 extends towards the front end of the vertical anti-collision beam 2. The horizontal anti-collision beam 5 and the vertical anti-collision beam 2 form an L-shaped structure. Before the vertical anti-collision beam 3 is impacted, the horizontal anti-collision beam 5 first resists the external impact to relieve the impact received by the vertical anti-collision beam 2. A protective energy-absorbing component 6 that forms a connection between the two horizontal anti-collision beams 5 is provided on the front end faces of the two horizontal anti-collision beams 5. The protective energy-absorbing component 6 first absorbs and releases the external impact force, and then transmits it to the horizontal anti-collision beam 5. When a collision occurs at the rear, the protective energy-absorbing component 6 first resists and releases the impact and then transmits it to the horizontal anti-collision beam 5. The horizontal anti-collision beam 5 further relieves the impact force by resisting collapse and then transmits it to the vertical anti-collision beam 2. The vertical anti-collision beam 2 is supported by the support beam 3 and together resists and releases the impact force at the rear, reducing the deformation of the vertical anti-collision beam 2. The rear impact can be released and resisted multiple times, with better protective performance. It can effectively intercept the vehicle behind, form protection for the rear of the vehicle, and prevent the vehicle behind from drilling under the vehicle.

[0019] The protective energy-absorbing component 6 includes a protective housing 601, a support plate 602, and a compression body 603. The protective housing 601 has a rectangular structure. The rear end face of the protective housing 601 is connected to the two horizontal anti-collision beams 5. The support plates 602 are arranged at intervals along the length direction of the protective housing 601 inside the protective housing 601. The compression body 603 is arranged between adjacent support plates 602. The compression body 603 is composed of two semi-cylinders that are symmetrically arranged and connected to each other. The open ends of the two semi-cylinders are respectively connected to the inner walls at both ends of the protective housing 601. The hollow structure of the protective housing 601 makes the vehicle lighter. The support plates 602 and the compression body 603 form support and resistance to the front and rear end faces of the protective housing 601 to increase the structural strength and structural stability of the protective housing 601 and reduce the deformation degree of the protective housing under re-impact. When the compression body 603 collapses at the front end face of the protective housing 601 and approaches the rear end face of the protective housing 601, the two semi-cylindrical compression bodies 603 are squeezed and deformed to slowly release and absorb the impact force, and then transfer it to the rear end face of the protective housing 601 to reduce the external force received by the horizontal anti-collision beam 5 and reduce its deformation degree.

[0020] A first structural strengthening component is provided between the top end of the support beam 3 and the rear end face of the vertical anti-collision beam 2, and a second structural strengthening component is provided between the bottom end of the support beam and the horizontal anti-collision beam. The first structural strengthening component and the second structural strengthening component make the structure between the vertical anti-collision beam 2, the horizontal anti-collision beam 5, and the support beam 3 stronger and more stable, and not easily deformed and collapsed.

[0021] The first structural strengthening component includes a first connecting portion 701, a second connecting portion 702, and a first inclined portion 703. The first connecting portion 701 and the second connecting portion 702 are symmetrically arranged at both ends of the first inclined portion 703. The first connecting portion 701 is connected to the top end of the support beam 3, and the second connecting portion 702 is connected to the rear end face of the vertical anti-collision beam 2. A triangular stable structure is formed among the first inclined portion 703, the support beam 3, and the vertical anti-collision beam 2. With its triangular stable structure, when the vertical anti-collision beam 2 is impacted, it forms effective resistance and support to prevent the vertical anti-collision beam 2 from deforming backward.

[0022] The second structural strengthening component includes a third connecting portion 801, a fourth connecting portion 802, and a second inclined portion 803. The third connecting portion 801 and the fourth connecting portion 802 are symmetrically arranged at both ends of the second inclined portion 803. The third connecting portion 801 is connected to the bottom end of the support beam 3, and the fourth connecting portion 802 is connected to the rear end face of the horizontal anti-collision beam 5. A triangular stable structure is formed among the second inclined portion 803, the support beam 3, and the horizontal anti-collision beam 5. With its triangular stable structure, when the horizontal anti-collision beam 5 is impacted, it forms effective resistance and support to prevent the horizontal anti-collision beam 8 from deforming greatly backward to effectively resist the rear impact force.

[0023] The outer surfaces of the vertical anti-collision beam 2, the support beam 3 and the horizontal anti-collision beam 5 are provided with cross-arranged reinforcing ribs 9, which effectively increase the wall thickness of the vertical anti-collision beam 2, the support beam 3 and the horizontal anti-collision beam 5, improve their structural strength and rigidity, and are not easily deformed or damaged under external impact, thereby effectively improving their protective performance.

[0024] There is an upper reinforcing rod 10 and a lower reinforcing rod 11 between the two vertical anti-collision beams 2. The upper reinforcing rod 10 and the lower reinforcing rod 11 are arranged horizontally up and down, and a vertically arranged middle reinforcing rod 12 is provided between the upper reinforcing rod 10 and the lower reinforcing rod 11. The upper reinforcing rod 10, the lower reinforcing rod 11, and the middle reinforcing rod 12 make the integrity between the two vertical anti-collision beams 2 better and increase the structural strength between the two vertical anti-collision beams 2. When they are subjected to force, the upper reinforcing rod 10, the lower reinforcing rod 11, and the middle reinforcing rod 12 can disperse the force to various places for resistance and support, so that the structure of the two vertical anti-collision beams 2 is more stable and not easy to deform.

[0025] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
