Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an integrated bracket for the rear instrument of a wide-body mining truck. Background Technology

[0002] With the continuous maturation and development of intelligent unmanned driving technology, its application in special vehicles such as mining wide-body dump trucks is becoming increasingly widespread. Against this backdrop, various unmanned driving perception systems have emerged; among them, the reasonable layout and reliable fixation of sensors such as radar and cameras on the vehicle body are the foundation for ensuring the stable operation of high-level autonomous driving functions such as environmental perception and path planning.

[0003] Currently, when installing unmanned driving perception systems at the rear of wide-body dump trucks, the industry often faces the problem of unreasonable layout. The simple brackets that are directly added generally have problems such as insufficient structural strength, scattered installation points, and lack of overall integrity. As a result, when the vehicle is driving under harsh working conditions, the accuracy of data collection by instruments such as cameras and radar is easily affected by the shaking of the brackets, and even equipment damage may occur.

[0004] In addition, existing solutions typically only consider the sensor itself and fail to integrate it with the vehicle's original rear components (such as rear combination lights) for coordinated protection, resulting in defects such as limited functionality and insufficient protection. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated support for instruments at the tail of a wide-body mining truck, which solves the technical problems existing in the prior art, such as unreasonable sensor installation layout, lack of effective protection for tail lights, and easy shaking of the support due to insufficient strength under harsh working conditions, thus affecting the stability of the equipment.

[0006] This utility model discloses an integrated support bracket for instruments at the tail of a wide-body mining truck, including: a support and fixing assembly, an L-shaped support plate, and two protective lamp covers; The support and fixing assembly includes: Support bars, horizontally set; Two bent plates are fixedly connected to both ends of the support strip, respectively; The connecting plate is vertically installed, and its top end is fixedly connected to the rear side of the support bar; A fixing plate is vertically installed, with its bottom end fixedly connected to the top surface of the support bar, and multiple first mounting holes are provided on both sides of the fixing plate; The L-shaped support plate includes a vertical section and a horizontal section, and a second mounting hole is provided on the horizontal section; The protective lamp cover includes: The back panel is arranged vertically and has a positioning groove. A U-shaped frame is fixedly connected to the front side of the back plate and surrounds the positioning groove; Multiple railings are vertically installed and horizontally spaced and fixed inside the U-shaped frame; The vertical section of the L-shaped support plate is attached to and detachably fixed to the lower front side of the connecting plate; the two back plates are attached to and detachably fixed to the rear ends of the connecting plate; and the two bending plates are detachably fixed to the top surfaces of the two U-shaped frames.

[0007] This application integrates the installation of various sensing devices with the protective function of the rear combination lights at the rear of the vehicle through a modular integrated design of the supporting and fixing assembly, L-shaped support plate, and protective lamp cover. Through rigid connections and detachable fixing between the components, a high-strength overall frame is formed, which effectively avoids the shaking of the equipment under harsh working conditions and ensures the stability of the sensing system. At the same time, it not only provides a compact and stable mounting base for various instruments, but also provides impact protection for the rear combination lights through the protective lamp cover. Ultimately, while ensuring complete functionality, it optimizes the structural layout of the mining truck's rear end, improves overall rigidity, and enhances maintenance convenience.

[0008] Based on the above technical solution, the solution of this application can be further improved as follows: Preferably, the support and fixing assembly includes: Multiple diagonal bracing plates are fixedly connected laterally to the bottom surface of the support bar and to the upper front side of the connecting plate. This design forms a stable triangular support structure, which significantly enhances the overall structural strength of the support and fixing assembly and effectively prevents deformation or shaking caused by bearing radar equipment and vehicle bumps.

[0009] Preferably, the connecting plate has a strip groove located between the two back plates. This solution provides a cable routing channel, effectively preventing cables from becoming tangled or damaged by friction with metal parts due to shaking, improving the standardization of installation and the reliability of equipment operation, and achieving a lightweight design.

[0010] Preferably, the top surface of the support strip is provided with a wire-passing groove, which corresponds vertically to the position of the strip groove. This solution improves the neatness of the wiring, avoids wear, interference and signal interference caused by messy cables, and greatly enhances the standardization and reliability of the entire electrical system.

[0011] Preferably, the top surface of the support bar has multiple third mounting holes on both sides of the wire groove, and the top surface of the support bar has multiple fourth mounting holes at both ends. This solution provides dedicated and standardized installation positions for different devices, ensuring the accuracy of the radar and camera installation positions, guaranteeing the consistency of their sensing references, and enabling independent installation and maintenance of both devices. They can be replaced or adjusted separately, thereby significantly improving the modularity and disassembly efficiency of maintenance operations.

[0012] Preferably, the mating area between the back plate and the connecting plate is provided with a plurality of first through holes, and the connecting plate is provided with a plurality of second through holes corresponding to the positions of the first through holes, for using bolt and nut assemblies passing through the first through holes and the corresponding second through holes to detachably fix the back plate to the connecting plate. With this solution, an integrated connection node is formed, which allows the connection between the back plate and the vehicle body steel frame, as well as the fixation between the back plate and the connecting plate, to be completed simultaneously with only one set of through bolt and nut assemblies. This greatly simplifies the assembly process, reduces the number of parts, reduces weight and cost, and significantly improves the convenience and efficiency of installation.

[0013] Preferably, at least one third through hole is provided on each side of the vertical section, and the third through hole corresponds to the position of the second through hole, so that the L-shaped support plate, the connecting plate and the back plate can be detachably fixedly connected by the same set of bolt and nut assemblies. By adopting this solution, the installation and fixing of the L-shaped support plate is also integrated, which minimizes the number of fasteners, simplifies the assembly relationship, significantly improves the compactness and installation efficiency of the overall structure, and also ensures the accuracy of the relative position between the three components and the integrity of the connection, which greatly enhances the modularity and structural rigidity of the bracket.

[0014] Preferably, the back plate has multiple fifth mounting holes located within the U-shaped frame and distributed around the positioning groove. This design allows the protective lampshade to be securely fixed to the frame, effectively transmitting the impact and vibration directly to the frame body, thereby enhancing the rigidity and reliability of the connection. Furthermore, since the mounting point is within the protection range of the U-shaped frame, damage to the bolt connection caused by external impacts is avoided.

[0015] Through the above technical solution, this utility model achieves the following beneficial effects: 1. This application integrates the installation of various sensing devices with the protective function of the rear combination lights of the vehicle through a modular integrated design of the supporting and fixing assembly, L-shaped support plate and protective lamp cover. Through rigid connection and detachable fixing between the components, a high-strength overall frame is formed, which effectively avoids the shaking of the equipment under harsh working conditions and ensures the stability of the sensing system. At the same time, it not only provides a compact and stable mounting base for various instruments, but also provides impact protection for the rear combination lights through the protective lamp cover. Ultimately, while ensuring complete functionality, it achieves the optimization of the tail structure layout of the mining truck, the improvement of overall rigidity and the enhancement of maintenance convenience. 2. By setting up a diagonal brace, this application forms a stable triangular support structure between the support bar and the connecting plate, transforming the original approximately "L"-shaped cantilever connection into a stable frame with high bending and torsional stiffness. This significantly enhances the overall structural strength of the support and fixing assembly, effectively preventing deformation or shaking caused by bearing radar equipment and vehicle bumps.

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] The terms “first”, “second”, etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as “first” or “second” may explicitly or implicitly include one or more of the stated features.

[0020] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0022] Example: like Figure 1 and Figure 5 As shown in the figure, this application discloses an integrated bracket for the rear instrument of a wide-body mining truck, which provides an integrated structure that integrates installation and protection functions for the sensing equipment of the unmanned driving system (such as radar assembly, unmanned driving camera, reversing image camera) and the original rear combination lights of the vehicle; its specific structure includes: a support and fixing assembly 1, an L-shaped support plate 2 and two protective lamp covers 3.

[0023] Understandably, dividing the entire support into the three main components facilitates manufacturing, transportation, and separate maintenance. Furthermore, the components are connected in a way that allows for a stable frame structure, ensuring sufficient strength and reliability under the harsh working conditions of mining trucks and preventing instrument swaying.

[0024] like Figure 2As shown, the support and fixing assembly 1 includes: support bar 11, two bent plates 12, connecting plate 13 and fixing plate 14, which is the core load-bearing structure of the entire bracket.

[0025] The support bar 11 is set horizontally to provide basic support so that the radar assembly can be installed at the center of its top surface, and the autonomous driving camera can be installed on the left and right sides of its top surface respectively.

[0026] Two bent plates 12 are fixedly connected to both ends of the support strip 11 for connection with the protective lamp covers 3 on both sides. They can be integrally formed with the support strip 11 through bending process, thereby reducing the processing difficulty and improving the structural stability. Moreover, their bending shape is used to fit with the top surface of the U-shaped frame 32 to enhance the stability and adaptability of the connection.

[0027] The connecting plate 13 is vertically set, and its top end is fixedly connected to the rear side of the support bar 11. This allows the middle part of the support bar 11 to be limited and fixed after installation, which greatly improves the stability of the support bar 11 and prevents the support bar 11 from shaking. It can also be integrally formed with the support bar 11 through a bending process, which reduces the processing difficulty and improves the structural stability.

[0028] The fixing plate 14 is vertically set, and its bottom end is fixedly connected to the top surface of the support bar 11. The fixing plate 14 has multiple first mounting holes 1401 on both sides for bolting to the rear side of the radar assembly through the first mounting holes 1401, so as to improve the reliability and stability of the radar assembly installation, thereby effectively preventing the radar from shaking while the vehicle is in motion and ensuring its detection accuracy.

[0029] like Figure 3 As shown, the L-shaped support plate 2 includes a vertical section 21 and a horizontal section 22. A second mounting hole 2201 is provided on the horizontal section 22 for bolting the reversing camera to the top surface of the horizontal section 22 through the second mounting hole 2201. The vertical section 21 is attached to and detachably fixed to the lower front side of the connecting plate 13, so that the L-shaped support plate 2 is stably supported.

[0030] Understandably, the L-shaped support plate 2 extends the mounting surface from the vertical plane to the horizontal plane, allowing the reversing camera to be securely mounted on the lower front side of the connecting plate 13. This increases the overall compactness of the layout, and the radar assembly above it and the protective light covers on both sides 3 can be used for blocking and protection, thereby reducing the probability of damage during use.

[0031] like Figure 4 As shown, the protective lamp cover 3 includes a back plate 31, a U-shaped frame 32, and multiple railings 33, which are used to realize the protective function of the rear combination lamp.

[0032] The back panel 31 is arranged vertically and has a positioning groove 3101. The positioning groove 3101 matches the shape of the original rear combination light of the vehicle, ensuring that the back panel 31 can be quickly and accurately installed and fixed in the appropriate position on the vehicle body.

[0033] The back plates 31 of the two protective lamp covers 3 are respectively attached to and detachably fixed to the rear ends of the connecting plate 13, thereby rigidly connecting the support and fixing assembly 1 with the originally independent protective lamp covers 3. This ensures the overall structural strength, realizes the partitioned layout and integration of functional components, provides stable protection for the rear combination lamps, and takes into account the convenience of maintenance.

[0034] The U-shaped frame 32 is fixedly connected to the front side of the back plate 31 and surrounds the positioning groove 3101, thereby forming a frame that surrounds the rear combination light and can resist rear collisions or scratches.

[0035] Two bending plates 12 are detachably fixed to the top surfaces of the two U-shaped frames 32, preferably by bolt connection, to facilitate disassembly and assembly and ensure connection stability. This rigidly connects the two independent protective lamp covers 3 on the left and right to the central support and fixing assembly 1, which greatly enhances the overall integrity and torsional rigidity of the bracket. It can effectively prevent the support bar 11 from swaying left and right when the vehicle bumps, and at the same time, it disperses the impact force that the support bar 11 may bear to the protective lamp cover 3 through the bending plates 12, thereby improving the reliability and service life of the overall structure.

[0036] Multiple railings 33 are vertically installed and horizontally spaced inside the U-shaped frame 32 to prevent impact from gravel and direct collision, and to reduce obstruction of lighting while providing physical protection.

[0037] This utility model integrates the installation of various sensing devices with the protective function of the rear combination lights of the vehicle through a modular integrated design of the supporting and fixing assembly 1, L-shaped support plate 2 and protective lamp cover 3. Through the rigid connection and detachable fixing between the components, a high-strength overall frame is formed, which effectively avoids the shaking of the equipment under harsh working conditions and ensures the stability of the sensing system. At the same time, it not only provides a compact and stable mounting base for various instruments, but also forms an impact-resistant protection for the rear combination lights through the protective lamp cover 3. Ultimately, while ensuring complete functionality, it achieves the optimization of the tail structure layout of the mining truck, the improvement of overall rigidity and the enhancement of maintenance convenience.

[0038] In some embodiments, such as Figure 1 and Figure 2 As shown, the support and fixing assembly 1 includes: Multiple diagonal bracing plates 15 are fixedly connected to the bottom surface of the support bar 11 at horizontal intervals and are fixedly connected to the upper front part of the connecting plate 13.

[0039] For example, the diagonal bracing plate 15 is a right-angled triangle and consists of two pieces. It achieves strong reinforcement of the connection node with the lightest structure, effectively resisting bending moments in the vertical direction and torsional deformation in the front-back direction, significantly improving the overall stiffness and structural stability.

[0040] Through the above design, a stable triangular support structure is formed between the support bar 11 and the connecting plate 13, transforming the original approximately "L"-shaped cantilever connection into a stable frame with high bending and torsional stiffness, thereby significantly enhancing the overall structural strength of the support and fixing assembly 1 and effectively preventing deformation or shaking caused by bearing radar and other equipment and vehicle bumps.

[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, a strip groove 1301 is provided on the connecting plate 13, and the strip groove 1301 is located between the two back plates 31.

[0042] The above design provides a wiring channel for the reversing camera installed on the L-shaped support plate 2, effectively preventing the cable from being messily tangled on the outside or damaged by friction with metal parts due to shaking, improving the standardization of installation and the reliability of equipment operation, and achieving a lightweight design.

[0043] Based on the above embodiments, such as Figure 2 As shown, a wire-passing groove 1101 is provided on the top surface of the support bar 11, and the wire-passing groove 1101 corresponds to the position of the strip groove 1301 in the vertical direction.

[0044] The above design allows the equipment cables of the radar assembly to pass through the strip 1301 in a concealed and orderly manner, thereby improving the neatness of the wiring and avoiding wear, interference and signal interference caused by messy cables, which greatly improves the standardization and reliability of the entire electrical system.

[0045] In this embodiment, as Figure 2 As shown, the top surface of the support bar 11 has multiple third mounting holes 1102 on both sides of the wire groove 1101, and multiple fourth mounting holes 1103 are provided at both ends of the top surface of the support bar 11.

[0046] Specifically, the third mounting hole 1102 is used to mount the radar assembly via a bolt and nut assembly, and the fourth mounting hole 1103 is used to mount the autonomous driving camera via a bolt and nut assembly.

[0047] The above design provides dedicated and standardized installation stations for different devices, ensuring the accuracy of radar and camera installation positions, guaranteeing the consistency of their sensing benchmarks, and enabling independent installation and maintenance of both devices. They can be replaced or debugged separately, thereby significantly improving the modularity of maintenance operations and disassembly efficiency.

[0048] In some embodiments, such as Figure 2 and Figure 4 As shown, the mating area between the back plate 31 and the connecting plate 13 is provided with a plurality of first through holes 3102, and the connecting plate 13 is provided with a plurality of second through holes 1302 corresponding to the positions of the first through holes 3102, for using bolt and nut assemblies that pass through the first through holes 3102 and the corresponding second through holes 1302 to detachably fix the back plate 31 to the connecting plate 13.

[0049] The above design creates an integrated connection node, which allows the connection between the back plate 31 and the vehicle body steel frame, as well as the fixation between the back plate 31 and the connecting plate 13, to be completed simultaneously using only one set of through bolt and nut assemblies. This greatly simplifies the assembly process, reduces the number of parts, lowers weight and cost, and significantly improves the convenience and efficiency of installation.

[0050] Based on the above embodiments, such as Figure 1 and Figure 3 As shown, at least one third through hole 2101 is provided on both sides of the vertical section 21. The third through hole 2101 corresponds to the second through hole 1302, so that the L-shaped support plate 2, the connecting plate 13 and the back plate 31 can be detachably fixedly connected by the same set of bolt and nut assemblies.

[0051] Through the above design, the installation and fixing of the L-shaped support plate 2 are also integrated, which minimizes the number of fasteners, simplifies the assembly relationship, significantly improves the compactness and installation efficiency of the overall structure, and ensures the accuracy of the relative positions between the three components and the integrity of the connection, greatly enhancing the modularity and structural rigidity of the bracket.

[0052] In some embodiments, such as Figure 4 As shown, the back plate 31 has a plurality of fifth mounting holes 3103, which are located inside the U-shaped frame 32 and distributed around the positioning groove 3101.

[0053] Through the above design, the protective lamp cover 3 can be firmly fixed to the frame, thereby effectively transmitting the impact and vibration directly to the frame body, thus enhancing the rigidity and reliability of the connection. Furthermore, since the installation point is located within the protection range of the U-shaped frame 32, damage to the bolt connection caused by external bumps is avoided.

In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
