TECHNICAL FIELD

[0001] The present application relates to the technical field of protective devices, and more particularly, to a front protective device and a vehicle. BACKGROUND

[0002] The body width of a wide body vehicle and the internal space of a carriage are large, and thus the carrying capacity and transportation efficiency are high, and the wide body vehicle is widely applied in various engineering fields. The working environment of the wide body vehicle is relatively harsh, and in order to avoid damage to key parts of the vehicle by stones and the like in the working environment, the vehicle is usually also provided with a front protective mudguard.

[0003] However, the front protective mudguard in the related art is inconvenient to disassemble, and the protection range is limited, and the protection effect is poor. CONTENT OF THE UTILITY MODEL

[0004] To solve the above problems, the present application provides a front protective device and a vehicle, aiming at improving the problems that the front protective mudguard in the related art is inconvenient to disassemble, and the protection range is limited, and the protection effect is poor.

[0005] In a first aspect, the present application provides a front protective device, comprising a protective assembly, a protective plate and a connecting piece; the protective assembly comprises a bottom plate and a frame, the frame is arranged around the bottom plate and is detachably connected with a vehicle frame; the protective plate is detachably connected with the frame and is arranged at an angle with the bottom plate; one end of the connecting piece is detachably connected with the protective plate, and the other end of the connecting piece is detachably connected with the vehicle frame.

[0006] Based on the front protective device provided by the embodiment of the present application, when it is needed to disassemble the front protective device from the vehicle frame, the one end of the connecting piece is separated from the protective plate, and the frame is separated from the vehicle frame, so that the front protective device and the vehicle frame can be quickly disassembled; when it is needed to install the front protective device to the vehicle frame, the one end of the connecting piece is connected with the protective plate, and the frame is connected with the vehicle frame, so that the front protective device and the vehicle frame can be quickly installed, which is convenient to disassemble and assemble, and the front protective device is connected with the vehicle frame through the frame and the connecting piece, so that the connection firmness and stability between the front protective device and the vehicle frame are high, thereby ensuring the protection reliability and protection effect of the front protective device. Secondly, the protective plate is arranged at an angle with the bottom plate, and the angle between the protective plate and the bottom plate can be adjusted according to the specific arrangement of the vehicle (for example, the downward angle and the downward height of the bottom plate are adjusted), so as to adjust the protection position of the front protective device, thereby expanding the protection range of the front protective device and improving the protection effect of the front protective device.

[0007] In one possible design, the frame includes a first frame and a second frame. The first frame includes a first connecting rod, a second connecting rod, and a third connecting rod, which are connected end-to-end to form a triangular structure. The first connecting rod is fixed to the base plate, and the second connecting rod is detachably connected to the frame. The second frame is positioned opposite the first frame on the base plate. The second frame includes a fourth connecting rod, a fifth connecting rod, and a sixth connecting rod, which are connected end-to-end to form a triangular structure. The fourth connecting rod is fixed to the base plate, and the fifth connecting rod is detachably connected to the frame.

[0008] In the above technical solution, the first and second frames are symmetrically arranged on the base plate in a triangular structure. This triangular structure effectively decomposes and transmits external forces to various parts of the protective assembly, thus avoiding localized stress concentration. Furthermore, the triangular structures on both sides of the base plate allow the protective assembly to better disperse the impact force from the front, resulting in better protection. The two triangular structures also improve the structural reliability of the protective assembly. Secondly, the first and second frames are hollow triangular structures, which are lightweight and easy to assemble and disassemble.

[0009] In one possible design, the frame further includes a seventh connecting rod and an eighth connecting rod; the seventh connecting rod is fixed to the base plate, one end of the seventh connecting rod is connected to the second connecting rod, and the other end of the seventh connecting rod is connected to the fifth connecting rod; the eighth connecting rod is fixed to the base plate and detachably connected to the protective plate, one end of the eighth connecting rod is connected to the third connecting rod, and the other end of the eighth connecting rod is connected to the sixth connecting rod; wherein the seventh connecting rod and the eighth connecting rod are parallel to each other.

[0010] In the above technical solution, the first frame and the second frame are connected by the seventh and eighth connecting rods, forming a closed frame. This enhances the overall integrity and spatial stability of the frame structure, making the entire system more robust. Secondly, the addition of support points disperses the impact force across multiple support points, reducing the likelihood of localized stress concentration and lowering the risk of damage due to excessive stress, thus improving the overall structural reliability of the protective components.

[0011] In one possible design, a first drainage hole is provided on the base plate near the eighth connecting rod.

[0012] In the above technical solution, the base plate is inclined, so that the water flowing down the base plate can be discharged from the front protection device through the first drainage hole, avoiding the problem of water accumulation in the front protection device and affecting its protective effect. In this way, the protective reliability of the front protection device can be further improved by setting the front protection device.

[0013] In one possible design, the frame includes a first frame and a third frame. The first frame includes a first connecting rod, a second connecting rod, and a third connecting rod, which are connected end-to-end to form a triangular structure. The first connecting rod is fixed to the base plate, and the second connecting rod is detachably connected to the frame. The third frame is positioned opposite the first frame on the base plate and includes a ninth connecting rod, a tenth connecting rod, an eleventh connecting rod, and a twelfth connecting rod, which are connected sequentially. The tenth connecting rod is fixed to the base plate, and the ninth and twelfth connecting rods are detachably connected to the frame, with a gap between the ninth and twelfth connecting rods.

[0014] In the above technical solution, the first and third frames are symmetrically arranged on the base plate in a triangular structure. The triangular structures on both sides of the base plate enable the protective assembly to better disperse the impact force from the front, thus achieving better protection. Furthermore, the two triangular structures further improve the structural reliability of the protective assembly. Secondly, a gap is formed between the ninth and twelfth connecting rods, allowing pipes and wiring harnesses in the wide-body vehicle to pass through, improving the convenience of later maintenance.

[0015] In one possible design, the protective plate is provided with at least one second drainage hole.

[0016] In the above technical solution, any water not drained from the base plate will flow to the protective plate and be discharged from the front protective device through the second drainage hole on the protective plate, thereby further improving the drainage effect and thus further improving the protective reliability of the front protective device.

[0017] In one possible design, a surrounding panel is provided around the protective plate.

[0018] In the above technical solution, the enclosure can prevent debris (such as flying sand and gravel) from falling into the protective plate during the driving of the wide-body vehicle, thereby improving the service life of the protective plate and ensuring the protective reliability of the protective plate.

[0019] In one possible design, the connector includes a first bend, a connecting portion, a second bend, and a third bend; the first bend is detachably connected to the protective plate, and the third bend is detachably connected to the frame.

[0020] In the above technical solution, the connector enables a fixed connection between the protective plate and the frame. Compared to a flat connector, the connector with a first bend, a connecting part, a second bend, and a third bend is more effective in preventing the impact of sand, gravel, and mud. Secondly, the detachable connection between the first bend and the protective plate prevents the connector from blocking the second drainage hole on the protective plate, thus preventing water accumulation. Furthermore, the detachable connection between the third bend and the frame prevents interference with the internal structure of the frame.

[0021] In one possible design approach, the protective components, protective plates, and connectors are made of steel.

[0022] Secondly, this application provides a wide-body vehicle, including a frame and a front protective device as described in any alternative embodiment of the first aspect, wherein the front protective device is connected to the frame. Attached Figure Description

[0032] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, and circuits have been omitted so as not to obscure the description of this application with unnecessary detail.

[0033] Wide-body trucks, with their greater width and spacious interior, offer higher cargo capacity and transportation efficiency, making them widely used in various engineering fields. Currently, the working environments in engineering are often harsh, meaning wide-body trucks operate in challenging conditions. For example, when driving in mines, the complex road conditions generate significant amounts of dust and mud. Similarly, wide-body trucks operate in dusty and complex environments at construction sites. To prevent damage to the chassis and critical components (such as the engine, transmission, fuel tank, and suspension) from rocks and other debris in the working environment, wide-body trucks are typically equipped with front mudguards. These mudguards are located below the front bumper, in front of the chassis. During driving, especially on uneven roads or off-road, the front mudguards prevent the chassis from contacting the ground (i.e., bottoming out), protecting the chassis from scratches and damage. The front mudguards can also prevent stones, mud and other debris from splashing into the engine compartment and transmission system of the wide-body vehicle, reducing the risk of damage to the engine compartment and transmission system. In addition, the front mudguards can protect the fuel tank and fuel lines from external impacts, avoiding safety hazards such as oil leaks.

[0034] However, the front mudguards in this technology have several drawbacks. For example, they affect the vehicle's appearance: installing front mudguards on wide-body vehicles reduces the overall harmony and aesthetics of the vehicle's design, a significant drawback for users who prioritize a cohesive and aesthetically pleasing appearance. Installation is complex: if not properly secured or installed in an inaccurate position, the front mudguard will be subjected to abnormal stress during vehicle operation, potentially leading to cracks and loosening over time, affecting its effectiveness and safety. The protective effect is limited: there is usually a gap between the front mudguard and the vehicle body, allowing mud, water, and sand to easily splash onto the vehicle. Furthermore, in winter, ice and snow may accumulate between the tires and the mudguard, affecting its normal use and even damaging the vehicle. Therefore, the front mudguards in this technology are inconvenient to remove, have limited protective coverage, poor protective effect, and are insufficient in terms of durability and compatibility with different vehicles.

[0035] Therefore, this application provides a front protective device and a wide-body vehicle. The front protective device can be quickly installed and removed from the vehicle frame, and the angle between the protective plate and the floor plate can be adjusted according to the specific layout of the vehicle to adjust the protective position of the front protective device, thereby expanding the protective range of the front protective device and improving the protective effect of the front protective device.

[0036] The front protective device and wide-body vehicle provided in this application are described below with reference to the accompanying drawings.

[0037] This application provides a wide-body vehicle, including a frame and a front protective device. The front protective device is connected to the frame and can prevent the frame of the wide-body vehicle from contacting the ground, thereby protecting the chassis from scratches and damage.

[0038] In one example, such as Figure 1 As shown, the front protective device provided in this application includes a protective component 1, a protective plate 2, and a connector 3. The protective component 1 includes a base plate 11 and a frame 12. The frame 12 is arranged around the base plate 11 and is detachably connected to the vehicle frame. The protective plate 2 is detachably connected to the frame 12 and is arranged at an angle to the base plate 11. One end of the connector 3 is detachably connected to the protective plate 2, and the other end of the connector 3 is detachably connected to the vehicle frame.

[0039] In this example, when the front protective device needs to be removed from the frame, it can be quickly disassembled by separating one end of the connector 3 from the protective plate 2 and separating the frame 12 from the frame. When the front protective device needs to be installed on the frame, it can be quickly installed by connecting one end of the connector 3 to the protective plate 2 and connecting the frame 12 to the frame. The installation and removal are convenient, and the front protective device is doubly connected to the frame through the frame 12 and the connector 3, resulting in a high degree of strength and stability in the connection between the front protective device and the frame, thus ensuring the reliability and effectiveness of the front protective device. Furthermore, the protective plate 2 and the base plate 11 are angled, allowing the angle between them to be adjusted according to the specific layout of the vehicle (e.g., adjusting the downward angle and height of the base plate 11) to adjust the protective position of the front protective device, thereby expanding its protective range and improving its protective effect. Thus, the front protective device provided in this application can effectively solve the shortcomings of related technologies, such as inconvenient installation and disassembly of front protective mudguards, unreliable structure, and inability to effectively resist the impact of mud, water, sand and gravel.

[0040] Optionally, the front protective device can be detachably connected to the frame using fasteners such as bolts and screws. Specifically, one end of the frame 12 and the connector 3 can be provided with at least one first threaded hole, and the corresponding position of the frame and one end of the connector 3 can be provided with at least one second threaded hole. Fasteners pass through the first and second threaded holes to connect the frame 12 and the connector 3 to the frame. Bolts and screws can quickly fix the front protective device to the frame, which is simple to operate and usually only requires simple tools (such as wrenches or screwdrivers). When the front protective device needs to be repaired, inspected, or replaced, the bolts and screws can be easily removed without damaging the structure itself, thus simplifying maintenance. Furthermore, during installation, the relative positional accuracy between the front protective device and the frame can be ensured by precisely controlling the tightening torque of the bolts and screws, avoiding problems caused by overtightening or loosening, and ensuring installation accuracy.

[0041] During vehicle operation, the base plate 11 of the protective assembly 1 effectively resists direct scratches and collisions from the ore. However, the protective assembly 1 will come into contact with external objects during the protection process. To prevent damage to the protective assembly 1 caused by external forces, in one example... Figure 2As shown, the protective component 1 provided in this application has a triangular structure in its overall side view. The triangular structure can effectively decompose and transmit external forces to various parts of the protective component 1. Specifically, when an impact force acts on the top of the triangular structure or any point, the force is decomposed into components along the two sides of the triangle. These components can be transmitted downwards along the sides of the structure, rather than being concentrated at a single point. This avoids local stress concentration in the protective component 1, reduces the risk of damage to the protective component 1 due to excessive stress, and improves the overall structural reliability of the front protective device. When the protective component 1 has a triangular structure in its overall side view, the front protective device appears as a trapezoidal structure in its side view.

[0042] To make the protective component 1 appear as a triangular structure in side view, in one example, such as Figure 3 As shown, the frame 12 may include a first frame 121 and a second frame 122. The first frame 121 includes a first connecting rod 1211, a second connecting rod 1212, and a third connecting rod 1213. The first connecting rod 1211, the second connecting rod 1212, and the third connecting rod 1213 are connected end to end to form a triangular structure. The first connecting rod 1211 is fixed to the base plate 11, and the second connecting rod 1212 is detachably connected to the frame. The second frame 122 is disposed opposite to the first frame 121 on the base plate 11. The second frame 122 includes a fourth connecting rod 1221, a fifth connecting rod 1222, and a sixth connecting rod 1223. The fourth connecting rod 1221, the fifth connecting rod 1222, and the sixth connecting rod 1223 are connected end to end to form a triangular structure. The fourth connecting rod 1221 is fixed to the base plate 11, and the fifth connecting rod 1222 is detachably connected to the frame.

[0043] In this example, the first frame 121 and the second frame 122 are symmetrically arranged on the base plate 11 and form a triangular structure. The triangular structures on both sides of the base plate 11 enable the protective assembly 1 to better disperse the impact force from the front, thus improving the protective effect. Furthermore, the two triangular structures further enhance the structural reliability of the protective assembly 1. Secondly, the first frame 121 and the second frame 122 are hollow triangular structures, which are lightweight and easy to assemble and disassemble.

[0044] In one example, please refer to Figure 3 and Figure 4As shown, the frame 12 also includes a seventh connecting rod 123 and an eighth connecting rod 124. The seventh connecting rod 123 is fixed to the base plate 11. One end of the seventh connecting rod 123 is connected to the second connecting rod 1212, and the other end of the seventh connecting rod 123 is connected to the fifth connecting rod 1222. The eighth connecting rod 124 is fixed to the base plate 11 and is detachably connected to the protective plate 2. One end of the eighth connecting rod 124 is connected to the third connecting rod 1213, and the other end of the eighth connecting rod 124 is connected to the sixth connecting rod 1223. The seventh connecting rod 123 and the eighth connecting rod 124 are parallel to each other.

[0045] In this example, the first frame 121 and the second frame 122 are connected by the seventh connecting rod 123 and the eighth connecting rod 124, forming a closed frame. This enhances the overall integrity and spatial stability of the frame 12 structure, making the entire system more robust. Secondly, the addition of support points disperses the impact force across multiple support points when applied to the protective component 1, reducing the likelihood of localized stress concentration and lowering the risk of damage due to excessive stress. This improves the overall structural reliability of the protective component 1.

[0046] To achieve a detachable connection between the frame 12, the base plate 11, and the protective plate 2, optionally, such as Figure 4 As shown, the base plate 11 has a first connecting member 111 and a second connecting member 112 bent on opposite sides. The second connecting member 112 fits into the seventh connecting rod 123, and the first connecting member 111 fits into the eighth connecting rod 124. Multiple opposing threaded holes are provided on the first connecting member 111, the eighth connecting rod 124, and the protective plate 2. Bolts, screws, and other fasteners are sequentially inserted into these threaded holes to achieve a fixed connection between the first connecting member 111, the eighth connecting rod 124, and the protective plate 2. Disassembly is simple; only the fasteners need to be removed. Furthermore, the first connecting member 111 and the eighth connecting rod 124 are in surface-to-surface contact, and the second connecting member 112 and the seventh connecting rod 123 are in surface-to-surface contact, resulting in a high degree of connection reliability.

[0047] In another example, such as Figure 5As shown, the frame 12 may include a first frame 121 and a third frame 125. The first frame 121 includes a first connecting rod 1211, a second connecting rod 1212 and a third connecting rod 1213. The first connecting rod 1211, the second connecting rod 1212 and the third connecting rod 1213 are connected end to end to form a triangular structure. The first connecting rod 1211 is fixed to the base plate 11 and the second connecting rod 1212 is detachably connected to the frame. The third frame 125 is disposed opposite to the first frame 121 on the base plate 11. The third frame 125 includes a ninth connecting rod 1251, a tenth connecting rod 1252, an eleventh connecting rod 1253 and a twelfth connecting rod 1254. The ninth connecting rod 1251, the tenth connecting rod 1252, the eleventh connecting rod 1253 and the twelfth connecting rod 1254 are connected in sequence. The tenth connecting rod 1252 is fixed to the base plate 11. The ninth connecting rod 1251 and the twelfth connecting rod 1254 are detachably connected to the frame, and a gap is formed between the ninth connecting rod 1251 and the twelfth connecting rod 1254.

[0048] In this example, the first frame 121 and the third frame 125 are symmetrically arranged on the base plate 11 in a triangular structure. The triangular structures on both sides of the base plate 11 enable the protective assembly 1 to better disperse the impact force from the front, thus improving the protective effect. Furthermore, the two triangular structures further enhance the structural reliability of the protective assembly 1. Secondly, a gap is formed between the ninth connecting rod 1251 and the twelfth connecting rod 1254, allowing pipes and wiring harnesses in the wide-body vehicle to pass through, improving the convenience of later maintenance.

[0049] Optionally, the ninth connecting rod 1251 and the twelfth connecting rod 1254 can be of the same length, or the length of the ninth connecting rod 1251 can be longer than the length of the twelfth connecting rod 1254, or the length of the twelfth connecting rod 1254 can be longer than the length of the ninth connecting rod 1251, as long as a gap can be formed between the ninth connecting rod 1251 and the twelfth connecting rod 1254. This application does not impose specific restrictions on this.

[0050] In one example, please refer to Figure 4 and Figure 6 As shown, a first drainage hole 11A is provided on the base plate 11 near the eighth connecting rod 124. The base plate 11 has an inclined structure, allowing water flowing down the base plate 11 to be discharged from the front protective device through the first drainage hole 11A, thus preventing water accumulation in the front protective device and affecting its protective effect. In this way, the protective reliability of the front protective device can be further improved by providing the front protective device. Optionally, the first drainage hole 11A can be an elliptical strip or other shapes; this application makes specific limitations on this.

[0051] To further improve drainage efficiency, please refer to an example. Figure 4 and Figure 6 As shown, the protective plate 2 is provided with at least one second drainage hole 2A. Water that is not completely drained from the bottom plate 11 will flow to the protective plate 2 and be discharged from the front protective device through the second drainage hole 2A on the protective plate 2, so as to further improve the drainage effect and thus further improve the protective reliability of the front protective device. Optionally, the second drainage hole 2A can be an elliptical strip or other shapes, and this application makes specific limitations on this.

[0052] In one example, such as Figure 7 As shown, the connector 3 includes a first bent portion 31, a connecting portion 32, a second bent portion 33, and a third bent portion 34 connected together. The first bent portion 31 is detachably connected to the protective plate 2, and the third bent portion 34 is detachably connected to the vehicle frame. In this example, the connector 3 can achieve a fixed connection between the protective plate 2 and the vehicle frame. Compared with a flat connector 3, the connector 3 with the first bent portion 31, connecting portion 32, second bent portion 33, and third bent portion 34 can more effectively prevent the impact of sand, gravel, and mud. Secondly, the detachable connection between the first bent portion 31 and the protective plate 2 avoids the connector 3 from blocking the second drainage hole 2A on the protective plate 2, thus preventing water accumulation. The detachable connection between the third bent portion 34 and the vehicle frame avoids interference with the internal structure of the vehicle frame. Optionally, the lengths of the first bent portion 31 and the third bent portion 34 can be extended or shortened according to actual needs to suit different vehicle models. This application does not impose specific limitations on this.

[0053] In one example, such as Figure 4 As shown, a surrounding panel 21 is provided around the protective plate 2. The surrounding panel 21 can prevent debris (such as flying sand and gravel) from falling into the protective plate 2 during the movement of the wide-body vehicle, thereby improving the service life of the protective plate 2 and ensuring the protective reliability of the protective plate 2. Optionally, the height of the surrounding panel 21 can be set according to requirements, and this application does not impose specific limitations on this.

[0054] Optionally, the protective component 1, protective plate 2, and connector 3 may be made of steel. Steel has extremely high tensile strength and can withstand significant mechanical stress, ensuring that the protective component 1, protective plate 2, and connector 3 remain robust and reliable even in harsh environments, thereby guaranteeing the reliability of the front protective device. Furthermore, steel possesses good toughness and impact resistance, effectively resisting external impacts and preventing the front protective device from cracking or being perforated, thus extending its service life. Other materials capable of achieving the above functions may also be used for the protective component 1, protective plate 2, and connector 3; this application does not impose specific limitations on these materials.

[0055] It is worth noting that the angles, heights, and specific installation positions of the protective components 1, protective plates 2, and connecting parts 3 in the front protective device provided in this application can be adjusted according to the different needs of different wide-body vehicles. Compared with the front protective mudguards in related technologies, the front protective device provided in this application has stronger applicability and greater inclusiveness, and can meet the needs of more vehicle models.

[0056] In summary, the front protective device provided in this application is easy to assemble and disassemble from the vehicle frame. When it is necessary to remove the front protective device from the vehicle frame, the front protective device can be quickly disassembled by separating one end of the connector 3 from the protective plate 2 and separating the frame 12 from the vehicle frame. When it is necessary to install the front protective device onto the vehicle frame, the front protective device can be quickly installed by connecting one end of the connector 3 to the protective plate 2 and connecting the frame 12 to the vehicle frame. The assembly and disassembly are convenient, and the front protective device is doubly connected to the vehicle frame through the frame 12 and the connector 3, which makes the connection between the front protective device and the vehicle frame more robust and stable, thereby ensuring the protective reliability and protective effect of the front protective device. Secondly, the protective plate 2 and the base plate 11 are set at an angle, and the angle between the protective plate 2 and the base plate 11 can be adjusted according to the specific layout of the vehicle (for example, adjusting the downward angle and downward height of the base plate 11) to adjust the protective position of the front protective device, thereby expanding the protective range of the front protective device and improving the protective effect of the front protective device. Thus, the front protective device provided in this application can effectively solve the shortcomings of related technologies, such as inconvenient installation and disassembly of front protective mudguards, unreliable structure, and inability to effectively resist the impact of mud, water, and sand. Secondly, the protective component 1 has a triangular structure in its side view. The triangular structure can effectively decompose and transmit external forces to various parts of the protective component 1. Specifically, when the impact force acts on the top of the triangular structure or any point, the force will be decomposed into components along the two sides of the triangle. These components can be transmitted downward along the sides of the structure, rather than being concentrated at a certain point, thereby avoiding local stress concentration in the protective component 1, reducing the risk of damage to the protective component 1 due to excessive force, and improving the overall structural reliability of the front protective device.
