Description

Technical Field

[0001] This utility model relates to the field of mining vehicle technology, and in particular to a vehicle anti-collision device and a mining dump truck. Background Technology

[0002] The front anti-collision device of a mining dump truck is a key component to ensure the safe operation of the vehicle. Its main function is to absorb collision energy under complex working conditions in the mining area and prevent damage to critical components such as the cab and engine. Due to the harsh road conditions in the mining area, vehicles frequently collide with sand and gravel materials, making the installation of a reliable anti-collision device crucial for ensuring personnel safety and reducing maintenance costs.

[0003] However, existing anti-collision devices still have some shortcomings. First, most existing anti-collision beams adopt a one-piece structure, which is prone to overall deformation during a collision, resulting in the need for complete replacement during maintenance and high maintenance costs. Second, conventional energy-absorbing structures lack effective graded energy absorption design and cannot achieve progressive crumple according to the collision intensity, resulting in low energy absorption efficiency. Finally, most anti-collision devices use welding or pin-shaft connections, which are not only structurally complex but also difficult to quickly disassemble and replace damaged parts after a collision.

[0004] Therefore, it is necessary to provide a vehicle collision avoidance device that is easy to maintain and has a graded energy absorption function to solve the above-mentioned problems in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a vehicle anti-collision device and mining dump truck that is easy to maintain and has a graded energy absorption function. Through the unique structure of the energy-absorbing plate with a specific bending angle and the built-in first corrugated plate, the collision energy is efficiently absorbed in a graded manner, so as to solve the problem of the single energy absorption effect and inability to graded collapse in the prior art.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows: This utility model provides a vehicle anti-collision device for a vehicle. The vehicle anti-collision device is installed on the front side of the vehicle and includes an anti-collision beam body, an energy-absorbing component mounted on the anti-collision beam body, and a mounting plate assembly for connecting the vehicle and the energy-absorbing component. The energy-absorbing component includes an energy-absorbing plate mounted on the anti-collision beam body and having a bending angle with the horizontal direction of the anti-collision beam body, and a first corrugated plate mounted on the inner side of the energy-absorbing plate.

[0007] Specifically, in this embodiment, the corrugation direction of the first corrugated plate is consistent with the bending direction of the energy-absorbing plate.

[0008] Specifically, in this embodiment, the energy-absorbing component further includes a first fixing bolt, and the energy-absorbing plate is detachably connected to the main body of the anti-collision beam through the first fixing bolt.

[0009] Specifically, in this embodiment, the anti-collision beam body includes at least one bundle tube and at least one crossbeam, and the crossbeam is equipped with a second corrugated plate.

[0010] Specifically, in this embodiment, the second corrugated plate extends along the direction of the crossbeam, and its corrugation direction is perpendicular to the direction of the impact force, so as to disperse the impact force to both sides of the crossbeam.

[0011] Specifically, in this embodiment, the main body of the anti-collision beam also includes an upper anti-collision beam and a lower anti-collision beam, and the upper anti-collision beam and the lower anti-collision beam are connected by the bundle tube to form a double-layer protective structure.

[0012] Specifically, in this embodiment, the mounting plate assembly includes a bent mounting plate and a threaded plate installed on the inner side of the bent mounting plate. The energy-absorbing plate is detachably mounted on the mounting plate by bolts corresponding to the threaded plate.

[0014] A mining dump truck includes a frame longitudinal beam and a vehicle anti-collision device as described in any one of the embodiments of the present invention, wherein the vehicle anti-collision device is detachably mounted on the frame longitudinal beam via the mounting plate.

[0015] Specifically, in this embodiment, the bending direction of the mounting plate is consistent with the extension direction of the frame longitudinal beam, which is used to transmit the collision force along the length direction of the frame longitudinal beam.

[0016] Compared with the prior art, the vehicle collision avoidance device provided by the embodiments of this application has many advantages, such as: (1) The vehicle collision avoidance device adopts a graded energy absorption design, which absorbs the initial collision energy by preferentially deforming the bending angle of the energy absorption plate, and at the same time enhances the structural rigidity through the first corrugated plate, forming a dual protection mechanism, which significantly improves the energy absorption efficiency under collisions at different speeds. (2) The vehicle collision avoidance device adopts a modular bolt connection structure, which allows key components such as the energy absorption plate and corrugated plate to be disassembled and replaced individually, greatly reducing maintenance costs and time.

[0028] Please refer to the following first. Figure 1 and Figure 2 The embodiments of this application provide a vehicle anti-collision device including an anti-collision beam body 1, an energy-absorbing component 2, and a mounting plate component 3.

[0029] Please refer to the following: Figure 3 and Figure 4 The anti-collision beam body 1 is installed on the front side of the vehicle and connected to the energy-absorbing component 2. The energy-absorbing component 2 includes an energy-absorbing plate 21 and a first corrugated plate 22. The energy-absorbing plate 21 is installed on the anti-collision beam body 1 and connected to the vehicle through a mounting plate assembly 3. When a vehicle collision occurs, the anti-collision beam body 1, as the main load-bearing component, bears the impact force from the front and absorbs the impact energy through the energy-absorbing component 2, reducing its own damage and thus protecting the vehicle and the safety of the occupants.

[0030] The energy-absorbing component 2 includes an energy-absorbing plate 21 mounted on the main body 1 of the crash beam, which is bent at an angle to the horizontal direction of the main body 1. A first corrugated plate 22 is installed on its inner side. During a collision, due to the bending angle between the first corrugated plate 21 and the main body 1 of the crash beam, the plate deforms, thereby absorbing impact energy and providing a buffering effect. The first corrugated plate 22 is used to enhance the deformation resistance of the hollow part of the energy-absorbing plate 21, assist the energy-absorbing plate 21 in absorbing impact energy, and further reduce damage to the main body 1 of the crash beam.

[0031] Mounting plate assembly 3 is used to connect the vehicle and energy absorption assembly 2, and to fix the anti-collision device on the vehicle so that the anti-collision device can work properly when the vehicle collides, and transmit and disperse the impact force.

[0032] Specifically, this application provides a vehicle anti-collision device for frontal protection of a vehicle, the innovation of which lies in the adoption of a modular, graded energy-absorbing structure design. The device mainly consists of an anti-collision beam body 1, an energy-absorbing component 2, and a mounting plate assembly 3. The energy-absorbing component 2 employs a unique structure with an energy-absorbing plate 21 having a specific bending angle, combined with a built-in first corrugated plate 22, to achieve efficient graded absorption of collision energy. Upon collision, the energy-absorbing plate 21 preferentially undergoes controllable deformation due to its bending angle design, while the first corrugated plate 22 effectively enhances the deformation resistance of the hollow portion of the energy-absorbing plate 21. This ensures sufficient absorption of initial collision energy while preventing premature failure of the energy-absorbing structure, thereby significantly improving the overall energy absorption efficiency and maintainability of the device while protecting the anti-collision beam body 1.

[0033] In this embodiment, the corrugation direction of the first corrugated plate 22 is consistent with the bending direction of the energy-absorbing plate 21. When a collision occurs, the energy-absorbing plate 21 absorbs energy due to deformation at the bending angle. At this time, since the corrugation direction of the first corrugated plate 22 is consistent with the bending direction of the energy-absorbing plate 21, it can better follow the deformation trend of the energy-absorbing plate 21 and provide more effective support in the hollow position of the energy-absorbing plate 21, further improving the ability of the energy-absorbing plate 21 to resist deformation. This allows the energy-absorbing component 2 to absorb impact energy more efficiently, reducing the impact force on the main body 1 of the anti-collision beam, thereby reducing the degree of damage to the main body 1 of the anti-collision beam.

[0034] In this embodiment, the energy-absorbing assembly 2 further includes a first fixing bolt 23, through which the energy-absorbing plate 21 is detachably connected to the anti-collision beam body 1. The first fixing bolt 23 passes through the corresponding mounting hole on the energy-absorbing plate 21 and the corresponding mounting part on the anti-collision beam body 1, and is detachably connected to the anti-collision beam mounting assembly by means of a first fixing nut 24, which facilitates disassembly and replacement when the energy-absorbing plate 21 is damaged or requires maintenance.

[0035] Specifically, the energy-absorbing plate 21 is preferably a steel plate bent at a large angle, the first corrugated plate 22 has a short corrugated structure, the energy-absorbing plate 21 is connected to the anti-collision beam body 1 by the first fixing bolt 23 and the first fixing nut 24, and the first corrugated plate 22 is welded to the inner side of the energy-absorbing plate 21.

[0036] In this embodiment, the main body 1 of the anti-collision beam includes at least one bundle tube 12 and at least one crossbeam 11, with a second corrugated plate (not shown in the figure) installed inside the crossbeam 11. The bundle tube 12 and the crossbeam 11 are preferably welded together to form a robust frame structure. When the vehicle encounters a frontal collision, the impact force first acts on the main body 1 of the anti-collision beam. At this time, the bundle tube 12 and the crossbeam 11, with their own rigidity and toughness, initially disperse and buffer the collision force. As the collision progresses, the crossbeam 11 deforms due to the force, and the internal second corrugated plate plays a crucial role. Its corrugated structure gradually compresses and wrinkles under pressure, absorbing a large amount of energy through its own deformation, slowing down the deformation speed and extent of the crossbeam 11, and preventing the impact force from being directly transmitted to the vehicle body. The three components work together to fully absorb and disperse the collision energy, effectively reducing the risk of damage to critical vehicle components.

[0037] Specifically, the second corrugated plate extends along the direction of the crossbeam 11, and its corrugation direction is perpendicular to the direction of the impact force, so as to disperse the impact force to both sides of the crossbeam 11.

[0038] The main body of the anti-collision beam 1 also includes an upper anti-collision beam and a lower anti-collision beam, which are connected by a bundle tube 12 to form a double-layer protective structure. The upper and lower anti-collision beams are installed at different heights on the front side of the vehicle. The upper anti-collision beam is used to deal with frontal collisions, while the lower anti-collision beam is used to prevent obstacles from intruding under the vehicle frame. The bundle tube 12 is evenly distributed between the upper and lower anti-collision beams to ensure the stability and uniform stress distribution of the structure.

[0039] In this embodiment, the mounting plate assembly 3 includes a bent mounting plate 31 and a threaded plate 33 installed on the inner side of the bent mounting plate 31. The energy-absorbing plate 21 is detachably mounted on the mounting plate 31 via a second fixing bolt 25 corresponding to the threaded plate 33. The mounting plate 31 is preferably a bent steel plate. The threaded plate 33 is welded to the inner side of the bent mounting plate 31. The energy-absorbing plate 21 is aligned with the threaded plate 33 on the mounting plate 31, and the second fixing bolt 25 is tightened to the threaded plate 33 through the corresponding hole on the energy-absorbing plate 21, thus completing the installation of the energy-absorbing plate 21. When a vehicle collides, the impact force is transmitted to the energy-absorbing plate 21, and the energy-absorbing plate 21 absorbs part of the energy through its own deformation. Meanwhile, the mounting plate 31 and the threaded plate 33 provide support for the energy-absorbing plate 21, ensuring that the energy-absorbing plate 21 maintains a stable connection during the energy absorption process, so that the energy absorption process can continue to be carried out effectively. If the energy-absorbing plate 21 is damaged and needs to be replaced, simply unscrew the second fixing bolt 25 connecting the energy-absorbing plate 21 and the threaded plate 33 to remove the damaged energy-absorbing plate 21, then install a new energy-absorbing plate 21, tighten the second fixing bolt 25 to the specified torque, and restore the function of the energy-absorbing assembly 2.

[0040] Specifically, the mounting plate assembly 3 also includes a support plate 32 installed at the bend of the mounting plate 31 to enhance its resistance to deformation. At the bend of the mounting plate 31, one side of the support plate 32 is tightly welded to the inner corner of the bend of the mounting plate 31, and the other side is welded to the outer corner of the bend of the mounting plate 31, forming a stable triangular support structure to enhance the deformation resistance of the mounting plate 31. When a vehicle collision occurs, the energy-absorbing plate 21 is subjected to impact force transmitted to the mounting plate 31, and the bend of the mounting plate 31 is prone to deformation. At this time, the support plate 32 can effectively enhance the deformation resistance of the mounting plate 31, ensuring the stability of the installation position of the energy-absorbing plate 21, thereby better exerting its energy-absorbing function.

[0041] In the event of a collision, the various structures of the anti-collision device work together to form a graded protection system: the energy-absorbing plate 21 undergoes controlled crumpling deformation through a large-angle bending design, absorbing the initial collision energy; the first corrugated plate 22 on its inner side guides the energy-absorbing plate 21 to fold along a predetermined direction through its corrugated structure, while simultaneously enhancing the deformation resistance of the hollow part; as the collision intensity increases, the main body 1 of the anti-collision beam begins to participate in bearing the load, in which the second corrugated plate inside the crossbeam 11 disperses stress through its wave structure, improving the bending stiffness of the crossbeam 11; the mounting plate assembly 3 guides the remaining impact force to the longitudinal beam of the frame through a bending structure, the welded threaded plate 33 ensures the strength of the bolt connection, and the support plate 32 strengthens the rigidity at the bend, preventing the mounting plate 31 from failing. Throughout the process, the anti-collision device adopts a detachable bolt connection design, allowing each component to be replaced individually after completing its energy absorption mission, ultimately achieving the triple protection goals of graded energy absorption, orderly deformation control, and convenient and efficient maintenance.

[0042] Another embodiment of this application provides a mining dump truck, including a frame longitudinal beam and a vehicle anti-collision device according to this embodiment. The mounting plate 31 of the vehicle anti-collision device is detachably connected to the frame longitudinal beam by bolts. Specifically, corresponding mounting holes are provided on the mounting plate 31 and the frame longitudinal beam. The connection between the two is achieved by passing bolts through these mounting holes and tightening them with nuts. This connection method facilitates the installation, disassembly, maintenance, and replacement of the anti-collision device when needed. The vehicle anti-collision device is installed at the front end of the mining dump truck, and its mounting plate 31 is connected to the front end portion of the frame longitudinal beam.

[0043] Specifically, the bending direction of the mounting plate 31 is consistent with the extension direction of the frame longitudinal beam, which is used to transmit the impact force along the length of the frame longitudinal beam.

[0044] The working principle of the vehicle collision avoidance device is explained in detail below.

[0045] Double-layer anti-collision beam structure: The upper and lower anti-collision beams are connected by a bundle tube 12 to form a double-layer protective structure. When a vehicle collision occurs, the double-layer anti-collision beams can first absorb and disperse a portion of the collision force. Through their own deformation and the buffering effect of the bundle tube 12, the collision energy is distributed between the upper and lower layers, reducing the impact force borne by a single component.

[0046] Energy-absorbing plate 21: The energy-absorbing plate 21 is made of a material with good energy absorption properties, preferably high-strength aluminum alloy or special composite material. During the collision, the energy-absorbing plate 21 undergoes plastic deformation, absorbing a large amount of collision energy through material deformation, thereby reducing the impact of the collision on the main structure of the vehicle.

[0047] Mounting plate assembly 3: Mounting plate 31 is bent and its bending direction is consistent with the extension direction of the frame longitudinal beam. Mounting plate 31 has a threaded plate 33 for connecting energy-absorbing plate 21, and a support plate 32 is also provided at the bend to enhance deformation resistance. When a collision occurs, the energy-absorbing plate 21 transfers the force it receives to the mounting plate 31. The mounting plate 31, through its structure, transmits the force along the length of the frame longitudinal beam, utilizing the overall structure of the frame longitudinal beam to disperse the collision force and prevent the force from concentrating in a localized area, thus avoiding severe damage to the vehicle structure.

[0048] Support plate 32: The support plate 32 installed at the bend of the mounting plate 31 can enhance the deformation resistance of the mounting plate 31. During a collision, the support plate 32 can prevent the mounting plate 31 from deforming excessively, ensuring that the mounting plate 31 can effectively transfer the collision force to the longitudinal beam of the frame. At the same time, it can also improve the structural stability of the entire anti-collision device, making it less prone to damage when subjected to large collision forces.

[0049] Integrated Connection Structure: The vehicle anti-collision device is detachably connected to the longitudinal beams of the frame via mounting plate 31. This connection method not only ensures the robustness of the connection but also allows the entire anti-collision device to function as a whole during a collision, working in concert with its various components to perform the anti-collision function. Furthermore, the detachable connection facilitates repair and replacement of the anti-collision device in case of damage.

[0050] Based on the specific structure and working principle described above, the vehicle collision avoidance device provided by the embodiments of this application can achieve many beneficial technical effects compared with the prior art, such as: (1) The vehicle collision avoidance device adopts a graded energy absorption design, which preferentially absorbs the initial collision energy through the bending angle of the energy absorption plate 21, and at the same time enhances the structural rigidity through the first corrugated plate 22, forming a dual protection mechanism, which significantly improves the energy absorption efficiency under collisions at different speeds. (2) The vehicle collision avoidance device adopts a modular bolt connection structure, which allows key components such as the energy absorption plate 21 and the corrugated plate to be disassembled and replaced individually, greatly reducing maintenance costs and time.

[0051] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
